USCB Financial Holdings, Inc.

2023 10-K

PART I

Item 1. Business

Overview

USCB Financial Holdings, Inc.,

a Florida corporation (the “Company”), was formed on December 17, 2021, to serve as

the

holding

company

for

U.S.

Century

Bank,

a

Florida

state-chartered

bank,

and

is

a

bank

holding

company

(a

“BHC”)

registered with

the Board

of Governors

of the

Federal

Reserve System

(the “Federal

Reserve”)

under the

Bank Holding

Company Act

of 1956,

as amended

(the “BHC

Act”). The

Company is

headquartered

in Miami,

Florida, and,

through the

Bank,

its

sole

direct

subsidiary,

operates

10

banking

centers

in

South

Florida

providing

a

wide

range

of

personal

and

business

banking products

and services

.

As of

December 31,

2023, the

Company

had total

consolidated

assets

of $2.3

billion.

The Bank commenced operations

on October 28, 2002 and

is a Florida state-chartered, non-Federal

Reserve System

member bank. Over the course

of 2021, the Bank simplified

its capitalization structure by

exchanging and/or repurchasing

all of

its issued

and outstanding

preferred shares,

including Class

C, Class

D, and

Class E

preferred stock.

In December

2021, the

Bank reached agreements

with holders of

its Class

B common

stock, to exchange

all outstanding

Class B common

stock for Class A common stock in a 1-for-5 stock exchange

.

On July 27,

2021, the Bank

completed an initial

public offering of 4,600,000

shares of its

Class A common

stock. Shares

of the Bank’s Class

A common stock were

sold at a price

to the public

of $10.00 per share

and began trading on

the Nasdaq

Stock Market under ticker symbol “USCB”.

On December

30, 2021

(the

“Effective

Date”),

the Company

acquired

all of

the

issued

and

outstanding

stock

of the

Bank in a

share exchange

(the “Reorganization”)

effected under

the Florida

Business Corporation

Act and

in accordance

with the

terms of

an Agreement and

Plan of

Share Exchange dated

December 27, 2021

between the Bank

and the

Company

(the “Share Exchange Agreement”). The Reorganization and

the Share Exchange Agreement were approved

by the Bank’s

stockholders at a special meeting of the Bank’s stockholders held on December 20,

  1. Pursuant to the Share Exchange

Agreement, on the Effective

Date each issued and outstanding

share of the Bank’s

Class A common stock was

converted

into and exchanged

for one share

of the Company’s Class

A common stock.

As a result,

the Bank became

the wholly owned

subsidiary

of

the

Company,

the

Company

became

the

holding

company

for

the

Bank

and

the

stockholders

of the

Bank

became stockholders of the Company.

Prior

to

the

Effective

Date,

the

Bank’s

Class

A

common

stock

was

registered

under

Section

12(b)

of

the

Securities

Exchange Act of 1934 (the “Exchange

Act”), and the Bank was subject to

the information requirements of the Exchange

Act

and, in accordance with Section 12(i) thereof, filed quarterly reports, proxy statements and other information with the FDIC.

As a result of the Reorganization, pursuant to Rule 12g-3(a) under the Exchange Act, the Company became the successor

registrant

to the

Bank, the

Company’s

Class

A common

stock

was

deemed

to

be

registered

under

Section

12(b) of

the

Exchange Act, and the Company became subject to the information requirements of the Exchange Act and is now required

to file

reports, proxy

statements and

other information with

the SEC.

The trading

symbol for

the Company’s Class

A Common

Stock is “USCB”, which is the same as the Bank’s former

trading symbol.

Prior to

the Reorganization,

the Company

had no

material assets

and had

not conducted

any business

or operations

except for activities related to its incorporation and the

Reorganization.

Our strategy

in becoming

a publicly

traded company

and forming

a BHC

was to

continue pursuing

organic growth

as

well as strategic acquisitions if the opportunity arises,

which efforts will be further facilitated by access

to public capital and

the added flexibility provided by a holding company structure.

In this Annual Report on Form 10-K, unless the context indicated otherwise, references to “we,” “us,”, and “our” refer to

the Company and the Bank,

as the contest dictates. However, if the discussion

relates to a period before

the Effective Date,

the terms refer only to the Bank.

Products and Services

Lending Services

Our mission

is to

provide high

value, relationship

-based banking

products, services

and solutions

to a

diverse

set of

clients in the

markets we serve. We focus

on serving small-to-medium sized businesses (“SMBs”) and

catering to the needs

of

local

business

entrepreneurs

and

professionals

Florida.

We

have

USCB Financial Holdings, Inc.

2023 10-K

providing comprehensive banking solutions

to SMBs to also secure the personal

retail deposit relationships of the owners,

operators, and employees of our commercial lending clients, which has

been a cornerstone of our deposit growth strategy.

In addition

to our

traditional commercial

banking services,

we are

among a

select number

of banks

of our

size within

our market

area that

can offer

certain specialty

banking products,

services and

solutions designed

for small

businesses,

homeowner associations,

law firms, medical

practices and other

professional services

firms, and global

banking services.

Our major specialty banking offerings include

the following:

Small

Business

Administration

(“SBA”)

lending:

Our

SBA

platform

originates

loans

under

Sections

7(a)

and 504

of the

SBA program.

The 7(a)

loan program,

SBA's most

common loan

program, includes

financial

help for small businesses

with special requirements

while the 504 loan program

provides long-term, fixed rate

financing of

up to $5.0

million for

major fixed assets

that promote

business growth

and job creation.

Since its

formation in

2018, the

platform serves

as an

opportunity to

generate commercial

and industrial

loans, or

C&I

loans, and to diversify our revenue stream through originating and

selling SBA 7(a) loans. As of December 31,

2023, the Bank is a Preferred Lending Partner with the SBA which

allows us to offer the full range of SBA loan

products and

to exercise

lending authority

at the

local bank

level, allowing

us to

make timely

credit decisions

for prospective clients.

Yacht lending:

Our yacht lending vertical

provides yacht financing for

larger vessels; transactions range

from

$750 thousand to $7.5 million.

We target high net-worth

clients, in one of the

most active yacht markets

in the

country.

Homeowner Association (“HOA”)

services:

We provide banking services

to HOAs and property

managers,

including deposit collection,

lockbox services, payment

services, and lending

products. Launched in

2016, we

a local bank, and a highly personalized

“white glove” approach to customer service.

Jurist Advantage and Private Client

Group services:

Our Jurist Advantage and Private

Client Group vertical

provides customized

banking solutions

for law

firms as

well as

their partners,

our relationships with

our law

firm clients to

accounts.

Global

Banking

services:

Our

Global

Banking

vertical

provides

correspondent

banking

services

for

banks

headquartered

in

certain

Latin

America

and

the

Caribbean

countries.

We

also

cross-sell

our

correspondent

banking relationships to

generate international personal

banking clients for

our Bank. Our compliance

team is

experienced in issues

related to foreign

banking, and we

have frequent and regular

open communication with

our foreign bank clients to ensure proper compliance

controls are maintained at such institutions.

Credit Practices

Our underwriting process is informed by a conservative credit culture

that encourages prudent lending. We believe our

strong asset quality

is due

to our

understanding of and

experience with businesses

within Florida,

in particular South

Florida,

our

long-standing

relationships

with

clients

and

our

disciplined

underwriting

processes.

Our

thorough

underwriting

processes

collaboratively

engage

our

seasoned

business

bankers,

credit

underwriters

and

portfolio

managers

in

the

analysis of each loan request.

We manage our credit risk by analyzing metrics related

to our different lines of business, which allows us to

maintain a

conservative

and

well-diversified

loan portfolio

reflective

of our

assessment

of various

industry

sectors.

Based

upon our

aggregate exposure to any given borrower relationship, we undertake a scaled review

of loan originations that may involve

senior credit officers, our Chief Credit Officer,

our Credit Committee or,

ultimately,

our Board of Directors (“Board”).

Deposit Products

We offer

traditional deposit

products, including

commercial and

consumer checking

accounts, money

market deposit

accounts, savings accounts, and

certificates of deposit

with a

variety of terms

and rates, as

well as a

robust suite of

treasury,

commercial payments,

and cash

management services.

Additionally,

we offer

ICS and

CDARS deposit

products that

are

FDIC-insured for our clients. Furthermore, we offer deposit products for municipalities and other public entities. Our deposit

products are mainly offered across our primary

geographic footprint.

diversification for

Seasonality

We do not believe our business to be seasonal

in nature.

Markets

Our primary banking market is South

Florida. Due to the recent

acceptance and expected ongoing emphasis on remote

work, coupled

with a

low tax

environment, warm

weather and

a strong

real estate

market has

encouraged companies

to

relocate some or all of their

operations to South Florida. We

believe this trend is further

demonstrated by recent relocation

initiatives undertaken by large financial institutions such as Blackstone Group Inc., Goldman Sachs Group Inc., and Citadel

Advisors

LLC,

all

of

which

have

established

operations

in

South

Florida.

We

believe

Florida

offers

long-term

attractive

banking opportunities.

Our largest concentration is in the Miami metropolitan statistical area; however, we are also focused

on growth in other urban Florida markets in which we

have a presence, such as Broward and Palm Beach counties

.

According to the

United States

Census Bureau’s

estimate,

Florida was

the third most

populous state in

the country in

2023 and the three largest population

centers were in Miami-Dade, Broward, and Palm

Beach counties (all located in South

Florida) in

  1. According

to estimates

from the

United States

Census Bureau,

from 2020

to 2023,

Florida’s

population

increased to 22.6 million residents, an increase of 1.0 million new residents. The percentage change in

Florida’s population

between April 2020 and July 2023 alone was 5.0% according

to the United States Census Bureau.

Competition

Our markets are highly competitive,

and we compete with a wide range of lenders and other financial institutions within

our markets,

including local,

regional,

national,

and international

commercial

banks

and credit

unions.

We

also compete

with mortgage companies, brokerage

firms, trust service providers, consumer

finance companies, mutual funds,

securities

firms,

insurance

companies,

third-party

payment

processors,

financial

technology

companies,

or

Fintechs,

and

other

financial intermediaries on various

of our products and

services. Some of our competitors

are not subject to the

regulatory

restrictions

and

the

level

of

regulatory

supervision

applicable

to

us.

Many

of

our

competitors

are

much

larger

financial

institutions that have greater financial

resources than we do

and compete aggressively for market

share. These competitors

attempt to gain market share through their financial product

mix, pricing strategies and larger banking center networks.

Interest rates

on both

loans and

deposits and

prices of

fee-based services

are significant

competitive factors

among

financial

institutions

generally.

Other

important

competitive

factors

include

convenience,

quality

of

customer

service,

availability and quality of digital offerings, community

reputation, and continuity of personnel and services.

Emerging Growth Company

We are an “emerging growth

company,”

or “EGC”, as defined in the Jumpstart

Our Business Startups Act of 2012 (the

“JOBS Act”). As such, we are eligible to take advantage of certain exemptions from various reporting requirements that are

applicable

to

other

public

companies

that

are

not

“emerging

growth

companies,”

including,

but

not

limited

to,

not

being

required to comply with the auditor

attestation requirements of Section

404 of the Sarbanes-Oxley Act,

reduced disclosure

obligations

regarding

executive

compensation

in

our

periodic

reports

and

proxy

statements,

and

exemptions

from

the

requirements of

holding a

non-binding advisory

vote on

executive compensation

and shareholder

approval of

any golden

parachute payments not previously approved.

In addition,

Section

107

of

the

JOBS

Act

also

provides

that

an

EGC can

take

advantage

of

the

extended

transition

period provided

in Section

7(a)(2)(B) of

the Securities

Act of

1933, as

amended (the

“Securities Act”),

for complying

with

new or revised accounting standards. In other

words, an EGC can delay the adoption

of certain accounting standards until

those standards would otherwise apply to private

companies. We intend to take advantage

of the benefits of this extended

transition period, for as long as it is available.

We will

remain an

EGC until

the earliest

to occur

of (i)

the end

of the

fiscal year

following the

fifth anniversary

of the

completion of the Bank’s initial public offering in 2021,

(ii) the last day of the first fiscal year in

which the Company's annual

gross revenues exceed $1.24 billion, (iii)

the date that the Company becomes

a “large accelerated filer” as defined

in Rule

12b-2 under the Exchange Act which would

occur if the market value of the

Company's common stock that is held

by non-

affiliates exceeds $700 million as of the last business day

of the Company’s most recently completed second

fiscal quarter

(June 30th for the

Human Capital Resources

We respect the values

and diversity throughout our organization

and the community. Diversity and inclusion are integral

parts of

our organization’s

culture. We

seek the

active engagement

and participation

of people

with diverse

backgrounds

and

ethnicities.

We

are

taking

steps

to

create

programs

to

ensure

that

we

are

organized

in

a

way

where

the

unique

contributions of each individual in our Company is

recognized and supported. Each team member is to

be treated fairly with

equal access to opportunities and resources for success. Additionally,

we run homebuyer educational and financial literacy

workshops in an effort

to reach the

financing needs of

the sectors of our

communities in which

these workshops are

most

needed.

Our human capital

objectives include attracting,

developing and retaining

the best available

talent from a

diverse pool

of

candidates

for

the

Company.

To

do

so,

we

strive

to

maintain

competitive

pay

and

benefits,

regularly

updating

our

compensation

structure

and

periodically

reviewing

our

compensation

and

benefits

programs.

Additionally,

the

Company

identifies

opportunities

and

paths

for

the

development

of

our

staff,

and

we

seek

to,

whenever

possible,

fill

positions

by

promotion within. The Company recognizes that the skills and knowledge of its employees

are critical to the success of the

organization, and promotes training and continuing education

as an ongoing function for employees.

We recognize

the importance

of our

employee's

financial

health and

well-being,

and offer

benefits such

as a

401(k)

retirement savings plan and make both matching and profit-sharing contributions to that plan. Benefit programs available to

eligible

employees

include,

in

addition

to

the

401(k)

retirement

savings

plan,

health

and

life

insurance,

employee

paid

holidays and other benefits.

We value and

promote diversity and

inclusion in every

aspect of our

business and at

every level within

the Company.

We recruit, hire, and promote

employees based on their individual

ability and experience and in

accordance with Affirmative

Action and Equal

Employment Opportunity

laws and regulations.

Our policy is

that we

do not discriminate

on the basis

of

race, color,

religion, sex,

gender,

sexual orientation,

ancestry,

pregnancy,

medical condition,

age, marital

status, national

origin, citizenship status, disability veteran status, gender identity, genetic information, or any other status protected by law.

At December 31, 2023,

we had 196

full-time equivalent employees.

None of our

employees are parties

to a collective

bargaining agreement. We believe that our employees are our greatest asset and vital to our success. As such, we seek to

hire and retain the best

candidate for each position, without regard to

age, gender, ethnicity,

or other protected class status,

but

with

an

appreciation

for

a

diversity

of

perspectives

and

experiences.

We

have

designed

a

compensation

structure

including an array of benefit plans and programs that

we believe is attractive to our current and prospective

employees.

Regulation and Supervision

Bank holding

companies, banks, and

their affiliates are

extensively regulated under

federal and

state law

and regulation.

These laws

and regulations

have a

material effect

on the

operations of

USCB Financial

Holdings, Inc.

and its

direct and

indirect subsidiaries, including U.S. Century Bank.

Statutes, regulations and

regulatory policies limit

the activities in

which we may

engage and the

conduct of our

permitted

activities and establish capital requirements with which we must comply. The regulatory framework is intended primarily for

the

protection

of

depositors,

borrowers,

customers

and

clients,

the

FDIC

insurance

funds

and

the

banking

system

as

a

whole, and not for the protection of our shareholders or creditors. In many cases, the applicable regulatory authorities have

broad

enforcement

power

over

bank

holding

companies,

banks

and

their

subsidiaries,

including

the

power

to

impose

substantial fines and other penalties for violations of laws

and regulations.

Further,

the

regulatory

system

imposes

reporting

and

information

collection

obligations.

Banking

statutes

and

regulations are subject

to change,

and additional statutes,

regulations, and corresponding

guidance may

be adopted. We

are unable to predict these future changes or the effects, if any, that these changes could have on the business, prospects,

revenues, and results of operations of the Bank and Company.

The material

statutory and

regulatory requirements

that are

applicable to

us are

summarized below.

The description

below is not intended to summarize all laws

and regulations applicable to us. These summary descriptions are not

intended

to be

a complete

explanation

of such

laws

and regulations

and

their

effects

on

USCB Financial

Holdings,

Inc. and

U.S.

Century Bank and are qualified

in their entirety by reference

to the actual laws and

regulations. You

should refer to the full

text of the statutes, regulations, and corresponding guidance

for more information.

2018 Regulatory Reform

In May 2018

the Economic

Growth, Regulatory

Relief and

Consumer Protection

Act (the “2018

Act”), was

enacted to

modify or remove

certain financial reform

rules and regulations, including

some of those

implemented under the

Dodd-Frank

Wall Street Reform

and Consumer Protection

Act (“Dodd-Frank Act”) enacted

in 2010. While the 2018

Act maintains most

of the

regulatory

structure established

by the

Dodd-Frank Act,

it amends

certain aspects

of the

regulatory framework

for

small depository

institutions

with assets

of less

than $10

billion and

for large

banks

with assets

of more

than $50

billion.

Many of these changes resulted in meaningful regulatory

relief for community banks such as U.S. Century Bank.

The 2018 Act, among other matters, expanded

the definition of “qualified mortgages”

which may be held by a financial

institution

and

simplified

the

regulatory

capital

rules

for

financial

institutions

and

their

holding

companies

with

total

consolidated assets of less

than $10 billion by instructing

(as described below) the

federal banking regulators to

establish

a single “Community Bank Leverage Ratio” of between 8 and 10 percent to

replace the leverage and risk-based regulatory

capital ratios.

The 2018

Act also

expanded the

category of

holding companies

that may

rely on

the “Small

Bank Holding

Company and Savings and Loan Holding Company Policy Statement” (the “SBHC Policy”) by raising the maximum amount

of assets a

qualifying holding company may

have from $1.0

billion to $3.0

billion. This expansion also

excluded such holding

companies

from

the minimum

capital

requirements

of

the Dodd-Frank

Act. In

addition,

the

2018

Act included

regulatory

relief

for

community

banks

regarding

regulatory

examination

cycles,

call

reports,

the

Volcker

Rule

(proprietary

trading

prohibitions), mortgage disclosures and risk weights for certain

high-risk commercial real estate loans.

Bank and Bank Holding Company Regulation

As a Florida-chartered state bank, U.S. Century Bank

is subject to ongoing and comprehensive supervision, regulation,

examination, and enforcement by the FDIC and the Florida Office

of Financial Regulation (“FOFR”). The FOFR supervises

and regulates

all areas

of our

operations including,

without limitation,

the making

of loans,

the issuance

of securities,

the

conduct

of

our

corporate

affairs,

the

satisfaction

of

capital

adequacy

requirements,

the

payment

of

dividends,

and

the

establishment or closing

of banking centers.

In addition, our

deposit accounts

are insured

by the Deposit

Insurance Fund

(the “DIF”)

administered by

the FDIC to

the maximum

extent permitted

by law,

and the FDIC

has certain

supervisory and

enforcement powers over us.

Any entity that directly or

indirectly controls a bank

must be approved by the

Federal Reserve under the

Bank Holding

Company

Act

of

1956

(the

“BHC

Act”)

to

become

a

bank

holding

company.

Bank

holding

companies

are

subject

to

regulation, inspection, examination, supervision and enforcement

by the Federal Reserve under the BHC Act. The Federal

Reserve's jurisdiction also extends to any company that is directly

or indirectly controlled by a bank holding company.

USCB Financial Holdings, Inc.,

which controls U.S. Century

Bank, is a bank holding

company and, as such,

is subject

to ongoing and comprehensive supervision, regulation,

examination and enforcement by the Federal Reserve.

Notice and Approval Requirements Related to Control

Banking

laws

impose

notice,

approval,

and

ongoing

regulatory

requirements

on

any

shareholder

or

other

party

that

seeks to acquire

direct or indirect

“control” of an

FDIC-insured depository

institution. These laws

include the BHC

Act and

the Change in Bank

Control Act. Among other things,

these laws require regulatory filings

by individuals or entities that

seek

to acquire

direct or

indirect

"control" of

an FDIC-insured

depository

institution. The

determination

of whether

an investor

"controls" a depository

institution is based

on all of

the facts and

circumstances surrounding

the investment. As

a general

matter, a party is deemed to conclusively control a depository institution or other

company if the party owns or controls 25%

or more of any class of

voting stock. Subject to rebuttal, a party may

be presumed to control a depository institution or

other

company if the investor owns or controls 10% or more of any class

of voting stock (and the entity’s securities are registered

under the Exchange Act or, if not, the investor would be

the largest shareholder). Except under limited circumstances, bank

holding companies are prohibited from acquiring, without prior

approval, control of any other bank or

bank holding company

or substantially all the assets thereof or more than 5% of the voting shares of a bank or bank holding company which is not

already a subsidiary.

Source of Strength

All companies, including bank holding companies, that directly or indirectly control an insured depository institution, are

required to serve as a source

of strength for the institution. Furthermore,

the Federal Reserve policy

is that a bank holding

company should stand ready

to use available resources

to provide adequate capital

to its subsidiary banks

during periods

of financial

stress or

adversity and

should maintain

the financial

flexibility and

capital-raising capacity

to obtain

additional

resources for

assisting its subsidiary

banks. Under

this requirement,

USCB Financial

Holdings, Inc.

in the future

could be

required to provide financial assistance

to U.S. Century Bank should

it experience financial distress.

Such support may be

Table of Contents

9

USCB Financial Holdings, Inc.

2023 10-K

required at times when, absent this statutory and Federal Reserve policy requirement, a bank holding company may not be

inclined to

provide it.

A bank

holding company’s failure

to meet

its obligations

to serve

as a

source of

strength to

its subsidiary

banks will generally be considered

by the Federal Reserve to

be an unsafe and unsound

banking practice or a violation

of

the Federal Reserve’s regulations, or both.

Safety and Soundness Regulation

As an insured depository

institution, we are subject to

prudential regulation and supervision

and must undergo regular

on-site examinations by our state and federal banking agencies. The cost of examinations of insured depository institutions

and any affiliates are assessed

by the appropriate agency against

each institution or affiliate that

is subject to examination

as it deems

necessary or

appropriate. We

file quarterly

consolidated reports

of condition

and income, or

call reports,

with

the FDIC and FOFR.

The federal banking

agencies have also

adopted guidelines establishing safety

and soundness standards for

all insured

depository institutions including U.S. Century Bank. The

safety and soundness guidelines relate to,

among other things, our

internal

controls,

information

systems,

cybersecurity,

internal

audit

systems,

loan

underwriting

and

documentation,

anti-

money laundering policies and procedures, transactions

with insiders, risk management, compensation, asset

growth, and

interest

rate

exposure.

These

standards

assist

the

federal

banking

agencies

with

early

identification

and

resolution

of

problems at insured depository

institutions. If we were

to fail to meet or

otherwise comply with any

of these standards, the

FDIC could require us to submit a

plan for achieving and maintaining compliance.

If a financial institution fails to

submit an

acceptable compliance plan, or fails in any material respect to implement a compliance plan that has been accepted by the

FDIC, the FDIC is

required to issue an

order directing the

institution to cure the

deficiency.

Until the deficiency cited

in the

order is cured, the

FDIC may restrict

the financial institution’s

rate of growth, require

the financial institution to

increase its

capital, restrict

the rates

the institution

pays on

deposits or

require the

institution to

take any

action the

regulator deems

appropriate

under

the

circumstances.

Noncompliance

with

the

standards

established

by

the

safety

and

soundness

guidelines may

also constitute

grounds for

other

enforcement

action,

including cease

and desist

orders

and

civil

money

penalty assessments. In addition,

the FDIC could terminate

our deposit insurance if

it determines that

our financial condition

was unsafe or

unsound or that

we engaged in unsafe

or unsound practices that

violated applicable rules, regulations,

orders

or conditions enacted or imposed on us by our regulators.

During

the

past

decade,

the

bank

regulatory

agencies

have

increasingly

emphasized

the

importance

of

sound

risk

management processes

and strong

internal controls

when evaluating

the activities

of the

financial institutions they

supervise.

Properly managing risks has been identified as critical to the conduct of safe and sound banking activities and has become

even more

important as

new technologies, product

innovation and

the size

and speed

of financial

transactions have

changed

the nature of

banking markets. The

agencies have identified

a spectrum of

risks facing a

banking institution including,

but

not limited

to, credit,

market, liquidity, interest rate,

cybersecurity, operational, legal and

reputational risk. In

particular, recent

regulatory pronouncements

have focused

on operational

risk, which

arises from

the potential

that inadequate

information

systems,

operational problems,

breaches

in

internal

controls, fraud

or unforeseen

catastrophes

will result

in unexpected

losses. New

products and

services, use

of outside

vendors and

cybersecurity are

critical sources

of operational

risk that

financial institutions

are expected

to address

in the

current environment.

We have

active Board

and senior

management

oversight

policies,

procedures

and

risk

limits;

adequate

risk

measurement

and

monitoring

and

adequate

management

information systems; and comprehensive internal controls

to address these various risks.

Permissible Activities and Investments

Banking

laws

generally

restrict

the

ability

of

USCB

Financial

Holdings,

Inc.

to

engage

in

activities

other

than

those

determined

by the

Federal

Reserve

to

be

so

closely

related

to

banking

as

to

be

a

proper

incident

thereto.

The

Federal

Reserve has determined

by regulation that

certain activities are

closely related to

banking including operating

a mortgage

company,

finance company,

credit card

company,

factoring

company,

trust

company

or savings

association;

performing

certain

data

processing

operations;

providing

limited

securities

brokerage

services;

acting

as

an

investment

or

financial

advisor; acting as

an insurance agent

for certain types

of credit-related insurance;

leasing personal property

on a

full-payout,

non-operating basis; providing

tax planning and

preparation services; operating

a collection agency;

and providing certain

courier services. In

addition, the Gramm

-Leach-Bliley Act (the

“GLB Act”) expanded

the scope of

permissible activities for

a bank holding company that

qualifies as a financial holding company.

Under the regulations implementing

the GLB Act, a

financial holding company may engage

in additional activities that are financial

in nature or incidental or complementary

to

a financial activity

such as securities

underwriting, insurance underwriting and

merchant banking. USCB Financial

Holdings,

Inc. is not a financial holding company.

In addition, as a general matter, the establishment or acquisition

by USCB Financial Holdings, Inc. of

a non-bank entity,

or

the

initiation

of

a

non-banking

activity,

requires

prior

regulatory

approval.

In

approving

acquisitions

or

the

addition

of

activities,

the

Federal

Reserve

considers,

among

other

things,

whether

the

acquisition

or

the

additional

activities

can

USCB Financial Holdings, Inc.

2023 10-K

reasonably be expected

to produce benefits

to the public, such

as greater convenience,

increased competition or

gains in

efficiency,

that

outweigh

such

possible

adverse

effects

as

undue

concentration

of

resources,

decreased

or

unfair

competition, conflicts of interest or unsound banking practices.

Regulatory Capital Requirements

The federal banking

regulators have adopted

risk-based capital

adequacy guidelines for

bank holding companies

and

their subsidiary banks

and banks without bank

holding companies based on

the Basel III

standards. Under these guidelines,

assets and off-balance sheet items are assigned to specific risk categories, each with designated risk weightings. The risk-

based capital guidelines are designed to make regulatory

capital requirements more sensitive to differences

in risk profiles

among banks and bank holding

companies, to account for off-balance sheet

exposure, to minimize disincentives for

holding

liquid assets, and

to achieve greater

consistency in

evaluating the capital

adequacy of

major banks throughout

the world.

The resulting

capital ratio requirements

represent capital as

a percentage of

total risk-weighted assets

and off-balance sheet

items. Final

rules implementing the

capital adequacy guidelines

became effective, with

various phase-in periods,

on January

1, 2015

for

community

banks

such

as us.

All

of

the

rules

were

fully

phased

in

as of

January

1,

2019.

These

final

rules

represent a significant change to the prior general risk-based capital rules and are

designed to substantially conform to the

Basel III international standards.

In computing

total risk-weighted

assets, bank

and bank

holding company

assets are

given risk-weights

of 0%,

20%,

50%, 100%

and 150%.

In addition,

certain

off-balance

sheet items

are given

similar credit

conversion

factors

to convert

them to asset

equivalent

amounts to which

an appropriate risk-weight

will apply.

Most loans will

be assigned to

the 100%

risk

category,

except

for

performing

first

mortgage

loans

fully

secured

by

1-to-4

family

or

certain

multi-family

residential

properties, which carry

a 50%

risk rating. Most

investment securities (including,

primarily, general obligation claims on

states

or

other

political

subdivisions

of

the

United

States)

will

be

assigned

to

the

20%

category,

except

for

municipal

or

state

revenue bonds, which have a 50% risk-weight,

and direct obligations of the U.S.

Treasury or obligations backed

by the full

faith

and

credit

of

the

U.S.

government,

which

have

a

0%

risk-weight.

In

covering

off-balance

sheet

items,

direct

credit

substitutes,

including

general

guarantees

and

standby

letters

of

credit

backing

financial

obligations,

are

given

a

100%

conversion

factor.

Transaction-related

contingencies

such

as

bid

bonds,

standby

letters

of

credit

backing

nonfinancial

obligations,

and undrawn

commitments

(including

commercial

credit lines

with

an initial

maturity

of more

than

one year)

have

a

50%

conversion

factor.

Short-term

commercial

letters

of

credit

are

converted

at

20%

and

certain

short-term

unconditionally cancelable commitments have a 0% factor.

Under

the

final

rules,

minimum

requirements

increased

for

both

the

quality

and

quantity

of

capital

held

by

banking

organizations. In this respect, the final rules

implement strict eligibility criteria for regulatory capital instruments and improve

the methodology for

calculating risk-weighted

assets to enhance

risk sensitivity.

Consistent with the

international Basel III

framework, the rules include a new

minimum ratio of Common Equity

Tier 1 Capital to Risk-Weighted

Assets of 4.5%. The

rules also create a Common Equity Tier 1 Capital conservation

buffer of 2.5% of risk-weighted assets. This buffer

is added

to each of the three risk-based capital

ratios to determine whether an institution

has established the buffer.

The rules raise

the minimum ratio of Tier 1 Capital to Risk-Weighted Assets from 4% to 6% and

include a minimum leverage ratio of 4% for

all banking

organizations. If

a financial

institution’s

capital conservation

buffer

falls below

2.5% —

e.g., if

the institution’s

Common Equity

Tier

1 Capital

to Risk

-Weighted

Assets is

less than

7.0% —

then capital

distributions

and

discretionary

bonus payments will

be limited or

prohibited based on

the size of

the institution’s conservation buffer. The types

of payments

subject to this limitation include

dividends, share buybacks, discretionary payments on

Tier 1 instruments, and discretionary

bonus payments.

The

capital

regulations

may

also

impact

the

treatment

of

accumulated

other

comprehensive

income

(“AOCI”)

for

regulatory capital purposes. Under

the rules, AOCI generally

flows through to regulatory

capital, however, community banks

and their holding companies (if any) were allowed to make

a one-time irrevocable opt-out election to continue to treat AOCI

the same

as under

the old

regulations for

regulatory capital

purposes. This

election was

required to

be made

on the

first

call report

filed after

January 1,

  1. We

made the

opt-out election.

Additionally,

the rules

also permit

community banks

with less than

$15 billion in

total assets to

continue to count

certain non-qualifying

capital instruments issued

prior to May

19, 2010 as Tier 1 capital, including trust preferred securities

and cumulative perpetual preferred stock (subject to a limit of

25% of Tier 1 capital). However, non-qualifying

capital instruments issued on or after May 19, 2010 do not qualify for Tier 1

capital treatment.

In May 2016,

amendments to the

Federal Reserve’s SBHC Policy

became effective which increased

the asset threshold

to qualify

to utilize

the provisions

of the

SBHC Policy

from $500

million to

$1.0 billion.

Subsequently,

as part

of the

2018

Act, the

threshold

was

increased

to

$3.0

billion.

Bank

holding companies

which

are subject

to the

SBHC

Policy

are not

subject to compliance with

the regulatory capital requirements

described above until they

exceed $3.0 billion in

assets. As

a consequence, as of December

31, 2023, USCB Financial Holdings, Inc.

was not required to

comply with the requirements

set forth above

and will not

be subject to

such requirements

until such time

that its

consolidated total

assets exceed

$3.0

billion or

the Federal Reserve

determines that USCB

Financial Holdings, Inc.

is no

longer deemed to

be a

small bank

holding

company.

However,

if

USCB

Financial

Holdings,

Inc.

had

been

subject

to

the

requirements,

it

would

have

been

in

compliance with such requirements.

In

September

2019,

the

federal

banking

agencies

jointly

finalized

a

rule

intended

to

simplify

the

regulatory

capital

requirements described above for qualifying community banking organizations

that opt into the Community Bank Leverage

Ratio, or

CBLR,

framework,

as required

by Section

201 of

the Regulatory

Relief

Act. The

final rule

became

effective

on

January 1,

2020,

and the

CBLR framework

became

available for

banks to

use beginning

with

their

March

31, 2020

call

reports. Under

the final

rule, if

a qualifying

community

banking organization

opts into

the CBLR

framework and

meets all

requirements under the

framework, it will

be considered to

have met

the well-capitalized ratio

requirements under the

prompt

corrective action

regulations

described below

in this

Form 10-K

and will

not be

required to

report or

calculate

risk-based

capital. In order to

qualify for the CBLR

framework, a community

banking organization must

have a tier 1

leverage ratio of

greater

than

9%,

less

than

$10

billion

in

total

consolidated

assets,

off-balance

sheet

exposures

of

25%

or

less

of

total

consolidated

assets,

and

trading

assets

and

liabilities

of 5%

or less

of total

consolidated

assets.

Although

U.S. Century

Bank is a qualifying

community banking organization,

U.S. Century Bank has

elected not to opt

in to the CBLR

framework

at this time and will continue to follow the Basel III capital

requirements as described above.

As of

December 31,

2023 and

2022, the

U.S. Century

Bank qualified

as a

“well capitalized”

institution. See

Note 15

“Regulatory Matters” of the Consolidated Financial Statements

included in Item 8 of this Form 10-K for further details.

Prompt Corrective Action

Under the Federal

Deposit Insurance Act

(“FDIA”), the

federal bank regulatory

agencies must take

"prompt corrective

action"

against

undercapitalized

U.S.

depository

institutions.

The

capital-based

regulatory

framework

contains

five

categories

of

compliance

with

regulatory

capital

requirements,

including

"well

capitalized,"

"adequately

capitalized,"

"undercapitalized,"

"significantly

undercapitalized,"

and

"critically

undercapitalized,"

and

are

subjected

to

differential

regulation corresponding to the capital category within

which the institution falls.

An insured depository

institution is deemed

to be "well

capitalized" if

it has a

total risk-based

capital ratio

of 10.0% or

greater, a

tier 1 risk-based

capital ratio of 8.0%

or greater,

a Common Equity

Tier 1

risk-based capital ratio

of 6.5% and a

leverage ratio of 5.0%

or greater, and the institution is

not subject to

an order, written agreement, capital directive, or

prompt

corrective action

directive to

meet and

maintain a

specific level

for any

capital measure.

Under certain

circumstances,

a

well-capitalized, adequately

capitalized or

undercapitalized institution

may be

treated as

if the

institution were

in the

next

lower capital category if it is determined that the institution is in an unsafe or unsound condition or is engaging in an unsafe

or unsound practice.

The degree of

regulatory scrutiny

of a financial

institution will increase,

and the permissible

activities

of

the

institution

will

decrease,

as

it

moves

downward

through

the

capital

categories.

Under

specified

circumstances,

a

federal

banking

agency

may

reclassify

a

“well-capitalized”

institution

as

adequately

capitalized

and

may

require

an

adequately capitalized institution or an

undercapitalized institution to comply with

supervisory actions as if

it were in

the next

lower

category

(except

that

the

FDIC

may

not

reclassify

a

significantly

undercapitalized

institution

as

critically

undercapitalized).

A banking

institution that

is undercapitalized

is required

to submit

a capital

restoration

plan. Failure

to

meet

capital

guidelines

could

subject

the

institution

to

a

variety

of

enforcement

remedies

by

federal

bank

regulatory

agencies,

including:

termination

of

deposit

insurance

by

the

FDIC,

restrictions

on

certain

business

activities,

and

appointment of the FDIC as conservator or receiver.

At December 31, 2023, U.S. Century Bank was deemed to be a “well-capitalized” institution for purposes of the prompt

corrective action regulations and as such is not subject

to the above mentioned restrictions.

Commercial Real Estate Concentration Guidelines

The federal

banking regulators

have implemented

guidelines to

address increased

concentrations in

commercial real

estate

loans.

These

guidelines

describe

the

criteria

regulatory

agencies

will

use

as

indicators

to

identify

institutions

potentially

exposed

to

commercial

real

estate

concentration

risk.

An

institution

that

has

(i)

experienced

rapid

growth

in

commercial real

estate lending,

(ii) notable

exposure to

a specific

type of

commercial real

estate, (iii)

total reported

loans

for construction, land development,

and other land representing

100% or more of

total capital, or (iv) total

commercial real

estate

(including

construction)

loans

representing

300%

or

more

of

total

capital

and

the

outstanding

balance

of

the

institution’s

commercial real

estate portfolio

has increased

by 50%

or more

in the

prior 36

months,

may be

identified for

further supervisory analysis of a potential concentration risk.

As of December

31, 2023, our

ratio of construction

loans to total

risk-based capital

was 21%,

and therefore,

we were

under

the

100%

threshold

set

forth

in

clause

(iii)

in

the

paragraph

above.

However,

with

respect

to

clause

(iv)

in

the

paragraph above, as

of December

31, 2023, our

ratio of total

commercial real

estate loans

to total risk-based

capital was

Table of Contents

12

USCB Financial Holdings, Inc.

2023 10-K

384% and the outstanding balance of

the institution’s commercial real estate portfolio increased by 50% or

more in the prior

36 months.

As a

result, we

are deemed

to have

a concentration

in commercial

real estate

lending under

applicable regulatory

guidelines.

If a

concentration is

present, under

the federal

banking regulator’

guidance, management

should employ

heightened

risk management practices that address key elements,

including board and management oversight and strategic

planning,

portfolio management,

development

of underwriting

standards,

risk assessment

and monitoring

through

market analysis

and stress

testing, and

maintenance of

increased capital

levels as

needed to

support the

level of

commercial real

estate

lending.

To

address

the commercial

real

estate

lending

concentration,

U.S.

Century

Bank has

previously

established

a

commercial

real

estate

lending

framework

to

monitor

specific

exposures

and

limits

by

types

within

the

commercial

real

estate

portfolio,

including,

among

other

things,

annual

stress

testing

of

the

commercial

real

estate

portfolio,

and

takes

appropriate actions, as necessary.

Payment of Dividends and Share Repurchases

The ability of

the board of

directors of an

insured depository

institution to declare

a cash dividend

or other distribution

with respect to capital is subject

to federal and state statutory

and regulatory restrictions that

limit the amount available for

such

distribution

depending

upon

earnings,

financial

condition,

including

whether

the

institution

has

negative

retained

earnings, and cash needs of the institution,

as well as general business conditions.

Insured depository institutions are also

prohibited

from

paying

management

fees

to

any

controlling

persons

or,

with

certain

limited

exceptions,

making

capital

distributions, including dividends, if after such transaction the institution would be

less than adequately capitalized. We may

generally declare a dividend

from retained net profits

which accrued prior to

the preceding two

years, but we must,

before

the

declaration

of

a

dividend

on

our

common

stock,

under

applicable

Florida

law,

carry

20%

of

our

net

profits

for

such

preceding period

as is

covered by

the dividend

to our

surplus fund,

until the

same shall

at least

equal the

amount of

our

common stock and preferred stock,

if any, then issued and outstanding. Under Florida law, we are

prohibited from declaring

a

dividend

at

any

time

at

which

our

net

income

from

the

current

year

combined

with

the

retained

net

income

from

the

preceding two years is a loss or which would cause our capital accounts to

fall below the minimum amount required by law,

regulation, order,

or any written agreement

with a state or

federal regulatory agency.

Furthermore, under applicable

FDIC

regulations and policy,

because U.S. Century Bank has

negative retained earnings, it must obtain the

prior approval of the

FDIC before effecting a cash dividend or other capital

distribution.

A Federal Reserve policy statement on the payment

of cash dividends states that a bank holding

company should pay

cash dividends only to the

extent that the holding company’s net

income for the past year

is sufficient to cover both the

cash

dividends and

a rate

of earnings

retention that

is consistent

with the

holding company’s

capital needs,

asset quality

and

overall

financial

condition.

The

Federal

Reserve’s

policy

statement

also

provides

that

it

would

be

inappropriate

for

a

company experiencing serious financial problems to borrow funds to pay dividends.

Furthermore, under the federal prompt

corrective action

regulations, the

Federal Reserve

may prohibit

a bank

holding company

from paying

any dividends

if the

holding company’s bank subsidiary is classified

as “undercapitalized.” See “ - Prompt Corrective Action”

above.

Section 225.4(b)(1) of Regulation Y promulgated

by the Federal Reserve requires that

a bank holding company that is

not “well-capitalized” or “well-managed”,

or that is subject to any

unresolved supervisory issues, provide

prior notice to the

Federal Reserve for

any repurchase or

redemption of

its equity securities

for cash or

other value that

would reduce by

10

percent or more the bank

holding company’s consolidated

net worth aggregated over

the preceding 12-month period.

The

Federal

Reserve

may

disapprove

such

a

purchase

or

redemption

if

it

determines

that

the

proposal

would

constitute

an

unsafe or

unsound practice

or would

violate any

law,

regulation, Federal

Reserve order

or any

condition imposed

by,

or

written agreement

with, the Federal Reserve. As

of December 31, 2023, USCB

Financial Holdings, Inc. was

not subject to

any

formal

supervisory

restrictions

on

its

ability

to

pay

dividends

but

will

notify

the

Federal

Reserve

in

advance

of

any

proposed

dividend

to

the

Company's

shareholders

in

light

of

the

Bank's

negative

retained

earnings.

In

addition,

we

will

provide prior notification to the Federal Reserve prior to

effecting proposed share repurchases.

Incentive Compensation

Guidelines adopted by

the federal

banking agencies pursuant

to the

FDIA prohibit

excessive compensation as

an unsafe

and

unsound

practice

and

describe

compensation

as

excessive

when

the

amounts

paid

are

unreasonable

or

disproportionate to the services performed by an executive

officer, employee, director

or principal shareholder.

In June 2010,

the federal banking

agencies jointly

adopted the

Guidance on Sound

Incentive Compensation

Policies,

or GSICP.

The GSICP was

intended to ensure

that banking organizations

do not undermine

the safety and

soundness of

such organizations

by encouraging

excessive risk-taking.

This guidance,

which covers

all employees

that have

the ability

to expose the organization

to material amounts

of risk, either

individually or as

part of a group,

is based upon a

set of key

principles relating to

a banking organization’s

incentive compensation arrangements.

Specifically,

incentive compensation

Table of Contents

13

USCB Financial Holdings, Inc.

2023 10-K

arrangements should (i)

provide employee incentives

that appropriately balance risk

in a manner that does

not encourage

employees to expose their

organizations to imprudent risk,

(ii) be compatible with

effective controls and risk

management,

and (iii) be supported

by strong corporate governance,

including active and effective

oversight by the organization’s

board

of directors. Any deficiencies in our compensation

practices could lead to supervisory or enforcement

actions by the FDIC.

The

GSICP

Guidance

provides

that

enforcement

actions

may

be

taken

against

a

banking

organization

if

its

incentive

compensation arrangements or related risk-management control or governance processes pose a risk to the

organization’s

safety and soundness and the organization is not taking prompt and

effective measures to correct the deficiencies.

The

Dodd-Frank

Act

requires

the

federal

banking

agencies

and

the

SEC

to

establish

joint

regulations

or

guidelines

prohibiting incentive-based

payment arrangements

at specified

regulated entities,

such as

us, having at

least $1

billion in

total

assets

that

encourage

inappropriate

risk-taking

by

providing

an

executive

officer,

employee,

director

or

principal

shareholder

with

excessive

compensation,

fees,

or

benefits

or

that

could

lead

to

material

financial

loss

to

the

entity.

In

addition, these regulators must establish regulations or guidelines requiring enhanced disclosure to regulators of incentive-

based compensation

arrangements. The

federal banking

agencies proposed

such regulations

in April

2011

and issued

a

second proposed

rule in

April 2016.

The second

proposed rule

would apply

to all

banks, among

other institutions,

with at

least $1.0 billion in average

total consolidated assets.

Final regulations have not

been adopted as of the

date of this Form

10-K.

If

adopted,

these

or

other

similar

regulations

would

impose

limitations

on

the

manner

in

which

we

may

structure

compensation for our executives and other employees

that go beyond the requirements of GSICP.

The scope and content

of the

federal banking

agencies’ policies

on incentive

compensation are

continuing

to develop

and are

likely

to continue

evolving, but the timeframe for finalization of such policies

is not known at this time.

Limits on Transactions with Affiliates and

Insiders

Transactions

between

insured

financial

institutions

and

any

affiliate

are

governed

by

Sections

23A

and

23B

of

the

Federal Reserve Act. An affiliate

of an insured financial institution

is any company or entity which

controls, is controlled by

or

is

under

common

control

with

the

insured

financial

institution.

In

a

bank

holding

company

context,

the

bank

holding

company

of

an

insured

financial

institution

(such

as

the

Corporation)

and

any

companies

which

are

controlled

by

such

holding company

are affiliates of

the insured

financial institution.

Generally, Section 23A limits

the extent

to which

the insured

financial institution or its

subsidiaries may engage in

“covered transactions” with any one

affiliate to an amount equal

to 10%

of such institution’s

capital stock

and surplus, and

contains an

aggregate limit

on all such

transactions with

all affiliates

to

an amount equal to 20% of such capital stock and surplus. Section 23B applies to “covered transactions” as well as certain

other

transactions

and

requires

that

all

transactions

be

on

terms

substantially

the

same,

or

at

least

as

favorable

to

the

insured financial institution, as

those provided to

a non-affiliate. The term “covered

transaction” includes the making

of loans

to, purchase of

assets from

and issuance of

a guarantee to

an affiliate

and similar

transactions. Section

23B transactions

also include the provision of services and the sale of assets

by an insured financial institution to an affiliate.

Sections 22(g)

and (h)

of the

Federal Reserve

Act place

restrictions on

loans to

executive officers, directors

and principal

stockholders. Under

Section 22(h),

loans to

a director,

an executive

officer

and to

a greater

than 10%

stockholder

of an

insured

financial

institution,

and

certain

affiliated

interests

of

either,

may

not

exceed,

together

with

all

other

outstanding

loans to such

person and

affiliated interests,

the insured financial

institution’s loans

to one borrower

limit (generally

equal

to 15%

of

the

institution’s

unimpaired capital

and

surplus).

Section

22(h) also

requires

that

loans

to directors,

executive

officers and principal stockholders be made on terms substantially the same as offered in comparable transactions to other

persons unless the loans are made pursuant to a benefit or compensation program that (i) is widely available to employees

of the

institution and

(ii) does

not give

preference to

any director, executive

officer or

principal stockholder, or

certain affiliated

interests thereof, over other employees

of the insured financial institution.

Section 22(h) also requires prior board

approval

for the issuance of certain loans. In addition, the aggregate amount of

extensions of credit by an insured financial institution

to all insiders cannot

exceed the institution’s

unimpaired capital and

surplus. Furthermore, Section

22(g) places additional

restrictions on

loans to

executive officers.

At December

31, 2023,

U.S. Century

Bank was

in compliance

with the

above

restrictions.

FDIC Deposit Insurance

The FDIC is

an independent

federal agency

that insures the

deposits of federally

insured depository

institutions up

to

applicable limits. The FDIC also has certain regulatory,

examination and enforcement powers with respect to FDIC-insured

institutions.

The

deposits

are

insured

by

the

FDIC

up

to

applicable

limits.

As

a

general

matter,

the

maximum

deposit

insurance amount is $250 thousand per depositor.

Additionally,

FDIC-insured depository institutions are

required to pay deposit insurance

assessments to the FDIC. The

amount of

a particular

institution's deposit

insurance assessment

is based

on that

institution's risk

classification under

an

FDIC risk-based assessment system. An institution's

risk classification is assigned based on

its capital levels and the level

of supervisory concern the institution poses to the regulators.

Table of Contents

14

USCB Financial Holdings, Inc.

2023 10-K

Under the current

system, deposit

insurance assessments

are based

on a bank’s

assessment base,

which is

defined

as average total assets minus

average tangible equity.

For established small institutions,

such as the Bank, the

FDIC sets

deposit

assessment

rates

based

on

the

Financial

Ratios

Method,

which

takes

into

account

several

ratios

that

reflect

leverage, asset quality,

and earnings at

each individual institution

and then applies

a pricing multiplier

that is the same

for

all institutions. An

institution’s rate

must be within

a certain minimum

and a certain

maximum, and the

range varies based

on the

institution’s

composite CAMELS

rating. The

deposit insurance

assessment

is calculated

by multiplying

the bank’s

assessment base by the total base assessment rate.

In October 2022, the FDIC finalized a

rule that increased the initial base deposit insurance

assessment rates by 2 basis

points, beginning with the first

quarterly assessment period of 2023

(January 1, 2023 through

March 31, 2023). The FDIC,

as required under the FDIA, established a plan in

September 2020 (the “Restoration Plan”) to restore the DIF

reserve ratio

to meet or exceed

the statutory minimum

of 1.35% within eight

years. The Restoration

Plan did not

include an increase

in

the deposit

insurance assessment

rate. Based

on the

FDIC’s recent

projections,

however,

the FDIC

determined that

the

DIF reserve ratio

is at risk

of not reaching the

statutory minimum by

the statutory deadline

of September 30,

2028 without

increasing the

deposit insurance

assessment rates.

The increased

assessment would

improve the

likelihood that

the DIF

reserve ratio would reach the required minimum by the statutory deadline, consistent with the

FDIC’s amended Restoration

Plan. The FDIC

also concurrently maintained

the Designated Reserve

Ratio (“DDR”) for

the DIF at

2% for 2023. The

new

assessment rate schedules will remain

in effect unless and until the reserve

ratio meets or exceeds 2% in order to support

growth

in

the

DIF

in

progressing

toward

the

FDIC’s

long-term

goal

of

a

2%

DRR.

Progressively

lower

assessment

rate

schedules will

take effect

when the

reserve ratio

reaches 2%,

and again

when it

reaches 2.5%.

The revised

assessment

rate schedule will

remain in effect unless

and until the

reserve ratio meets

or exceeds 2%,

absent further action by

the FDIC.

Under the

FDIA, the

FDIC may

terminate deposit

insurance upon

a finding

that the

institution has

engaged in

unsafe

and unsound

practices,

is in

an unsafe

or unsound

condition

to continue

operations,

or has

violated any

applicable

law,

regulation, rule, order, or condition

imposed by the FDIC.

Depositor Preference

The FDIA provides

that, in the

event of the

"liquidation or other

resolution" of an

insured depository institution, the

claims

of depositors

of the institution

(including the

claims of

the FDIC as

subrogee of

insured depositors)

and certain claims

for

administrative

expenses

of

the

FDIC

as

a

receiver

will

have

priority

over

other

general

unsecured

claims

against

the

institution. Insured and

uninsured depositors,

along with the

FDIC, will have

priority in payment

ahead of unsecured,

non-

deposit creditors,

including U.S.

Century Bank,

with respect

to any

extensions of

credit they

have made

to such

insured

depository institution.

Overdraft Fee Regulation

The Electronic Fund Transfer Act prohibits

financial institutions from charging consumers fees

for paying overdrafts on

automated teller machines, or

ATMs,

and one-time debit card transactions,

unless a consumer consents,

or opts in, to the

overdraft service for those types

of transactions. If a consumer

does not opt in,

any ATM transaction or debit that overdraws

the consumer’s account

will be denied.

Overdrafts on

the payment

of checks

and regular

electronic bill

payments are

not

covered

by

this

new

rule.

Before

opting

in,

the

consumer

must

be

provided

with

a

notice

that

explains

the

financial

institution’s

overdraft

services,

including

the

fees

associated

with

the

service,

and

the

consumer’s

choices.

Financial

institutions

must

provide

consumers

who

do

not

opt

in

with

the

same

account

terms,

conditions

and

features

(including

pricing) that they provide to consumers who do opt in.

Federal Reserve System and Federal Home Loan

Anti-Money Laundering Regulation

As a financial

institution, we

must maintain

anti-money laundering

programs that

include established

internal policies,

procedures

and

controls,

a

designated

compliance

officer,

an

ongoing

employee

training

program,

and

testing

of

the

program by an independent audit function in accordance with the

Bank Secrecy Act of 1970, as amended (“BSA”), and the

regulations issued

by the

Department of

the Treasury

in 31

CFR Chapter

X, FDIC

Rule 326.8

and the

Florida Control

of

Money Laundering

and Terrorist

Financing in

Financial Institutions

Act. Financial

institutions are

prohibited from

entering

into specified

financial

transactions

and account

relationships

and must

meet enhanced

standards for

due

diligence and

“knowing your customer”

in their dealings

with foreign financial institutions,

foreign customers and other

high risk customers.

Financial

institutions

must

also

take

reasonable

steps

to

conduct

enhanced

scrutiny

of

account

relationships

to

guard

against money laundering

and to report transactions

that meet certain

dollar amount thresholds

as well as

any suspicious

transactions. Recent laws, such as the USA PATRIOT

Act, enacted in 2001, as described below,

provide law enforcement

authorities with increased access to financial information maintained

by banks.

Anti-money laundering

obligations have

been substantially

strengthened

as a

result of

the USA

PATRIOT

Act. Bank

regulators routinely examine institutions for compliance with these obligations, and this area has become a particular focus

of

the

regulators

in

recent

years.

In

addition,

the

regulators

are

required

to

consider

compliance

in

connection

with

the

regulatory

review

of

certain

applications.

In

recent

years,

regulators

have

expressed

concern

over

banking

institutions’

compliance

with

anti-money

laundering

requirements

and,

in

some

cases,

have

delayed

approval

of

their

expansionary

proposals. The regulators and other

governmental authorities have been

active in imposing “cease

and desist” orders and

significant money penalty sanctions against institutions

found to be in violation of the anti-money laundering regulations.

USA PATRIOT

Act

The USA

PATRIOT

Act became

effective

in October

2001 and

amended the

BSA. The

USA PATRIOT

Act requires

banks to establish anti-money laundering programs that

include, at a minimum:

a bank

compliance

program

that

contains

internal

policies,

procedures

and

controls

designed

to

implement

and

maintain the

bank’s compliance

with all

of the

requirements of

the USA

PATRIOT

Act, the

BSA and

related laws

and regulations;

bank wide

systems

and procedures

for monitoring

and reporting

of suspicious

transactions

and

activities;

a designated compliance officer;

employee training for bank employees;

an independent audit function to test the efficacy

of the bank’s anti-money laundering program;

procedures to verify the identity of each bank customer upon

the opening of accounts;

heightened due diligence policies,

procedures and controls applicable to

certain foreign accounts and

relationships;

and

required reports to law enforcement and/or financial regulators to assist in the deterrence and prevention of money

laundering activities.

Additionally,

the USA PATRIOT

Act requires each financial

institution to develop a

customer identification program,

or

CIP, as part of its anti-money

laundering program. The

key components of

the CIP are

identification verification, government

list comparison,

notice and

record retention.

The purpose

of the

CIP is

to enable

the financial

institution to

determine the

true identity

and anticipated

account activity

of each

customer.

To

make this

determination, the

financial institution

must,

among other things, collect certain information from customers at the time they enter

into the customer relationship with the

financial institution.

This information must

be verified within

a reasonable time.

Furthermore, all customers

must be

screened

against any CIP-related government

lists of known or suspected

terrorists or other “sanctioned”

persons. In May 2018, the

U.S. Treasury’s

Financial Crimes

Enforcement Network,

or FinCEN,

issued a

final rule

under the

BSA requiring

banks to

identify and verify

the identity of

the natural persons

behind their customers

that are legal

entities—the beneficial

owners.

The

Anti-Money

Laundering

Act

of

2020

(the

“AML

Act’)

and

within

the

AML

Act,

the

Corporate

Transparency

Act

(the

“CTA”),

was enacted in

January 2021. The

AML Act is

intended to be

a comprehensive

reform and modernization

to U.S.

bank

secrecy

and

anti-money

laundering

laws.

Among

other

things,

it

codifies

a

risk-based

approach

to

anti-money

laundering compliance

for financial

institutions; requires the

development of

standards for evaluating

technology and

internal

processes

for BSA

compliance;

expands

enforcement-

and investigation

-related

authority,

including

increasing

available

sanctions

for

certain

BSA

violations

and

instituting

BSA

whistleblower

incentives

and

protections.

The

CTA

establishes

uniform beneficial

ownership reporting

requirements for

corporations, limited

liability companies,

and other similar

entities

formed or

registered to

do business in

the United

States. The

CTA authorizes U.S. Treasury’s Financial Crimes

Enforcement

Network (“FinCEN”) to collect that information and share it with authorized government authorities and

financial institutions,

subject

to

effective

safeguards

and

controls.

In

December

2023,

FinCEN

issued

regulations

regarding

access

to

the

beneficial

ownership

information

collected

under

the

CTA.

We

and

our

affiliates

have

adopted

policies,

procedures

and

controls designed to comply with the BSA, the AML Act, the

CTA and the USA

PATRIOT

Act.

The Office of Foreign Assets Control

The Office of Foreign Assets Control (the “OFAC”)

is responsible for helping to ensure that U.S. entities do not engage

in transactions with

“enemies” of

the United States,

as defined by

various Executive

Orders and Acts

of Congress.

OFAC

publishes lists of

names of

persons and organizations

suspected of aiding,

harboring or

engaging in terrorist

acts; owned

or

controlled

by,

or

acting

on

behalf

of

target

countries;

and

narcotics

traffickers.

Such

persons

are

referred

to

as

“sanctioned” persons.

If a bank finds

a name on

any transaction, account

or wire transfer

that is on

an OFAC

list, it must

freeze the account

and/or block the transaction or wire transfer. We utilize an outside vendor to oversee

the inspection of our accounts and the

filing of any notifications.

We also monitor

high-risk OFAC

areas such as new

accounts, wire transfers

and customer files.

These checks are performed using software that is updated each time

a modification is made to the lists provided by

OFAC

and other agencies of Specially Designated Nationals

and Blocked Persons.

Consumer Laws and Regulations

Our activities

are subject

to a

variety

of federal

and state

statutes and

regulations

designed to

protect consumers

in

transactions with

banks. Interest

and other

charges collected

or contracted

for by

us are

subject to

state usury

laws and

federal laws concerning interest rates. Our loan

operations are also subject to federal laws

applicable to credit transactions,

such as:

the

Truth-In-Lending

Act

(“TILA”),

and

Regulation

Z,

governing

disclosures

of

credit

and

servicing

terms

to

consumer borrowers and including substantial new requirements for mortgage lending and servicing, as mandated

by the Dodd-Frank Act

the Home Mortgage Disclosure Act of 1975 and Regulation C, requiring

financial institutions to provide information

to enable the

public and public

officials to

determine whether

a financial institution

is fulfilling its

obligation to help

meet the housing needs of the communities they serve;

the Equal Credit

Opportunity Act and

Regulation B, prohibiting

discrimination on the

basis of race,

color,

religion,

or other prohibited factors in extending credit;

the Fair

Credit Reporting Act

of 1978,

as amended by

the Fair

and Accurate Credit

Transactions Act, and Regulation

V, as well as the rules and

regulations of the FDIC governing the

use and provision of information

to credit reporting

agencies, certain identity theft protections and certain

credit and other disclosures;

the Fair

Debt Collection

Practices Act

and Regulation

F,

governing the

manner in

which consumer

debts may

be

collected by collection agencies; and

the Real Estate Settlement Procedures Act,

(“RESPA”), and Regulation X, which governs aspects of the settlement

process for residential mortgage loans.

Our deposit operations are also subject to federal laws,

such as:

the FDIA, which, among other things, limits the amount of

deposit insurance available per account to $250,000 and

imposes other limits on deposit-taking;

the Right to

Financial Privacy Act,

which imposes a

duty to maintain

the confidentiality of

consumer financial records

and prescribes procedures for complying with administrative subpoenas

of financial records;

Check Clearing for

the 21st Century

Act (also known

as “Check 21”),

which gives “substitute

checks,” such as

digital

check images and copies made from that image, the

same legal standing as the original paper check;

the Electronic

Funds Transfer

Act and

Regulation E,

which governs

automatic deposits

to and

withdrawals

from

deposit accounts

and customers’

rights and

liabilities arising

from the

use of

ATMs

and other

electronic banking

services; and

the Truth

in Savings

Act and

Regulation DD,

which requires

depository institutions

to provide

disclosures so

that

consumers can make meaningful comparisons about depository

institutions and accounts.

These

laws

and

regulations

mandate

certain

disclosure

requirements

and

regulate

the

manner

in

which

financial

institutions must deal with clients when

taking deposits or making loans to

such clients. We must comply with the applicable

provisions of these consumer protection laws and regulations as part of both

our ongoing client relations and our regulatory

compliance obligations.

Financial Privacy and Cybersecurity

Banking organizations

are

subject to

many federal

and state

laws and

regulations

governing the

collection,

use and

protection of customer information.

Under the privacy protection

provisions of the GLB

Act and related regulations,

we are

Table of Contents

17

USCB Financial Holdings, Inc.

2023 10-K

limited

in

our

ability

to

disclose

non-public

information

about

consumers

to

nonaffiliated

third

parties.

These

limitations

require disclosure of

privacy policies to consumers

and, in some circumstances,

allow consumers to

prevent disclosure of

certain

personal

information

to

a

nonaffiliated

third

party.

Federal

banking

agencies,

including

the

FDIC,

have

adopted

guidelines for establishing information security standards

and cybersecurity programs for implementing safeguards.

These

guidelines,

along

with

related

regulatory

materials,

increasingly

focus

on

risk

management

and

processes

related

to

information technology and the use of third parties in the

provision of financial services.

In

addition,

the

federal

banking

agencies

have

adopted

a

rule

to

establish

computer-security

incident

notification

requirements

for

bank

holding

companies,

banks

and

their

service

providers.

Under

the

rule,

banking

organizations

are

required to notify their primary

federal regulators within 36 hours

of any incident that has materially

disrupted or degraded,

or is

reasonably

likely to

materially disrupt

or degrade,

the banking

organization’s

ability to

deliver banking

services to

a

material portion of

its client base,

jeopardize the

viability of key

operations, or

impact the financial

stability of

the financial

sector. The rule also imposes

certain notification requirements on third-party bank

service providers when they experience

a computer-security

incident that

has caused,

or is

likely to

cause a

material service

disruption or

degradation for

four or

more hours. In such case, the service provider is required to notify its bank-designated point of contact as soon as possible

upon discovery of the incident.

In addition to federal laws and regulations, we are subject

to state laws governing customer privacy and cybersecurity.

The Florida Information Protection Act of 2014 (“Florida Act”) requires notification of

the Florida Department of Legal Affairs

of any breach involving

personal information that

affects more than

500 people as

well as requiring notification

of affected

individuals of

a breach.

The Florida

Act also

requires us to

take reasonable

measures to protect

and secure

data in

electronic

form containing personal information and take all reasonable measures to dispose, or arrange for the disposal, of

customer

records containing

personal information

within our

custody or

control when

the records

are no

longer to

be retained.

We

incur

significant

costs

and

expenses

in

order

to

address

compliance

with

the

federal

and

state

customer

privacy

and

cybersecurity laws and regulations, and we expect such

costs and expenses will continue into the future.

Consumer Financial Protection Bureau

The Consumer Financial Protection Bureau (“CFPB”) is

an independent regulatory authority housed within the

Federal

Reserve Board. The CFPB has broad authority to regulate the offering and provision of consumer financial products and to

prevent institutions subject to its authority from engaging in “unfair

and deceptive or abusive acts or practices” with respect

to their

offering of consumer

financial products or

services. The CFPB

has the

authority to

supervise and examine

depository

institutions with more than

$10 billion in assets for

compliance with federal consumer

laws. The authority to

supervise and

examine depository institutions with

$10.0 billion or less in assets,

such as U.S. Century Bank,

for compliance with federal

consumer laws

remains largely

with those

institutions’

primary federal

regulators.

However,

the CFPB

may participate

in

examinations of these smaller

institutions on a “sampling

basis” and may refer

potential enforcement actions

against such

institutions to their

primary regulators. As such,

the CFPB may

participate in examinations of

U.S. Century Bank.

In addition,

states are

permitted to

adopt consumer

protection laws

and regulations

that are

stricter than

the regulations

promulgated

by the CFPB, and state attorneys general are permitted to

enforce consumer protection rules adopted by the CFPB against

certain institutions.

The Volcker Rule

The Dodd-Frank Act

prohibits (subject to

certain exceptions) us

and our

affiliates from engaging

in short term

proprietary

trading in securities and derivatives and from investing

in and sponsoring certain investment companies defined

in the rule

as “covered

funds” (including

not only

hedge funds,

commodity pools

and private

equity funds,

but also

a range

of asset

securitization structures

that do not

meet exemptive

criteria in the

final rules). This

statutory provision

is commonly

called

the “Volcker Rule.” At December 31, 2023, we are not

subject to the Volcker Rule because of our asset

size, which is below

the $10.0 billion Volcker Rule

threshold.

Community Reinvestment Act and Fair Lending Requirements

As

previously

noted,

we

are

subject

to

certain

fair

lending

requirements

and

reporting

obligations

involving

home

mortgage

lending

operations.

We

are

also

subject

to

certain

requirements

and

reporting

obligations

under

the

federal

Community Reinvestment Act (“CRA”).

The CRA and

its corresponding regulations are

intended to encourage banks

to help

meet the credit needs of

the communities they serve,

including low- and moderate

-income neighborhoods, consistent with

safe and sound banking practices.

Accordingly,

the

CRA

generally

requires

federal

banking

agencies

to

evaluate

the

record

of

a

financial

institution

in

meeting applicable

CRA requirements.

The CRA

further requires

the agencies

to take

into account

our record

of meeting

community

credit

needs

when

evaluating

applications

for,

among

other

things,

new

branches

or

mergers.

We

are

also

Table of Contents

18

USCB Financial Holdings, Inc.

2023 10-K

subject to analogous state CRA requirements

in Florida and certain other states

in which we may establish branch

offices.

In

connection

with

their

assessments

of

CRA

performance,

the

FDIC

and

FOFR

assign

a

rating

of

“outstanding,”

“satisfactory,”

“needs to

improve,” or

“substantial

noncompliance.”

We received

a “satisfactory”

CRA Assessment

Rating

from

both

regulatory

agencies

in

our

most

recent

CRA

examinations

in

2023.

In

addition

to

substantive

penalties

and

corrective measures that may be required for a violation of certain fair lending laws, the federal banking agencies may take

compliance with such laws and CRA

into account when regulating and supervising

other activities of the bank, including

in

acting

on

expansionary

proposals

such

as when

a bank

submits

an

application

to establish

bank

branches,

merge

with

another bank,

or acquire

the assets

and assume

the liabilities

of another bank.

An unsatisfactory

CRA and/or

fair lending

record could

substantially delay or

block any

such transaction.

The regulatory agency's

assessment of

the institution's

record

is

made

available

to

the

public

at

www.ffiec.gov/craratings.

Following

its

most

recent

CRA

performance

evaluation

in

October 2022, U.S. Century Bank received an overall

rating of "Satisfactory."

In October 2023, the

federal banking agencies jointly issued

a final rule to

revise the regulations implementing the

CRA.

The final rule takes effect

on April 1, 2024, with

staggered compliance dates; the applicability date

for most of the provisions

is January

1, 2026.

The changes

are designed

to encourage

banks to

expand access

to credit,

investment

and banking

services in low and moderate income

communities, adapt to changes in

the banking industry including mobile

and internet

banking, provide

greater clarity and

consistency in

the application

of the CRA

regulations and

tailor CRA evaluations

and

data

collection

to

bank

size

and

type.

The

final

rule

implements

a

revised

regulatory

framework

that,

like

the

current

framework, is based on

bank asset size and

business model. Under the

final rule, a new

“Retail Lending Test” is established

except with

banks with

total assets

of less

than $600

million as

of December

31 in

either of

the prior

two calendar

years

have the option to maintain

the current CRA evaluation

framework, referred to in

the final rule as the

“Small Bank Lending

Test,”

or opt into

the Retail Lending

Test.

The Retail Lending

Test

evaluates a bank’s

record of helping

to meet the

credit

needs of

its community

through the

origination and

purchase of

residential

mortgage, multi

-family,

small business,

small

farm and,

in certain

cases, automobile

loans. Banks

of all

sizes will

maintain the

option to

elect to

be evaluated

under a

strategic plan

with the

final rule

updating the

standards

for obtaining

approval for

such plan.

The final

rule continues

the

current

approach

of

requiring

banks

to

delineate

specific

“facility-based

assessment

areas,”

which

comprise

the

areas

around a bank’s main office, branches, and deposit-taking remote service facilities (e.g., ATMs). The final rule allows

banks

to receive CRA credit for any qualified community development

activity, regardless

of location.

Call Reports and Examination Cycle

All institutions, regardless of size, submit

a quarterly call report that includes

data used by federal banking agencies

to

monitor the condition, performance, and

risk profile of individual institutions

and the industry as a whole.

In June 2019, the

federal banking agencies issued a

final rule to permit insured depository

institutions with total assets of

less than $5 billion

that

do

not

engage

in

certain

complex

or international

activities

to

file

the

most

streamlined

version

of the

quarterly

call

report, and to reduce data reportable on certain streamlined

call report submissions.

Effect of Governmental Monetary Policies

The commercial banking

business is affected

not only by

general economic conditions,

but also by

the monetary policies

of the Federal Reserve. Changes in the discount rate

on member bank borrowing, availability of borrowing

at the “discount

window,”

open

market

operations,

changes

in

the

Fed

Funds

target

interest

rate,

the

imposition

of

changes

in

reserve

requirements against member banks’ deposits

and assets of foreign banking centers

and the imposition of and changes in

reserve requirements against certain

borrowings by banks and

their affiliates are

some of the

instruments of monetary

policy

available to the Federal Reserve. These

monetary policies are used in

varying combinations to influence overall growth and

distributions of bank loans, investments and deposits, which may affect interest rates charged

on loans or paid on deposits.

The monetary

policies of

the Federal

Reserve have

had a significant

effect on

the operating

results of

commercial banks

and are

expected to

continue

to do

so in

the future.

The Federal

Reserve’s

policies are

primarily

influenced

by the

dual

mandate

of

price

stability

and

full

employment,

and

to

a

lesser

degree

by

short-term

and

long-term

changes

in

the

international trade

balance and

in the

fiscal policies

of the

U.S. government.

Future changes

in monetary

policy and

the

effect of such changes on our business and earnings

in the future cannot be predicted.

Future Legislation and Regulation

Congress may enact legislation from time to time that affects

the regulation of the financial services industry,

and state

legislatures may enact legislation from time to time affecting the regulation of financial institutions chartered by or operating

in those states.

Federal and state

regulatory agencies

also periodically propose

and adopt changes

to their regulations

or

change the manner

in which existing

regulations are

applied or

interpreted. The

substance or

impact of pending

or future

legislation or regulation, or

the application thereof, cannot

be predicted, although enactment

of proposed legislation has

in

the past

and may

in the

future affect

the regulatory

structure under

which we

operate and

may significantly

increase our

costs, impede the efficiency

of our internal business

processes, require us to

increase our regulatory

capital or modify our

business

strategy,

or

limit

our

ability

to

pursue

business

opportunities

in

an

efficient

manner.

Our

business,

financial

condition, results

of operations

or prospects

may be

adversely affected,

perhaps materially,

as a

result of

any such

new

legislation or regulations.

Federal Securities Laws and the Sarbanes-Oxley Act

USCB

Financial

Holdings,

Inc.’s

common

stock

is

registered

with

the

SEC

under

Section

12(b)

of

the

Securities

Exchange Act of 1934. USCB Financial

Holdings, Inc. is subject to the

proxy and tender offer rules, insider trading reporting

requirements and restrictions, and certain other requirements

under the Securities Exchange Act of 1934.

As a public company,

USCB Financial Holdings, Inc. is also subject to

the Sarbanes-Oxley Act of 2002 (“SOA”), which

is applicable to all companies, both U.S. and non-U.S., that file periodic reports

under the Securities Exchange Act of 1934.

The stated goals of

the SOA were to increase

corporate responsibility, to provide for enhanced penalties for accounting and

auditing

improprieties

at

publicly

traded

companies

and

to

protect

investors

by

improving

the

accuracy

and

reliability

of

corporate disclosures

pursuant to

the securities

laws. The

SEC is

responsible for

establishing rules

to implement

various

provisions of

the SOA.

The SOA

includes specific

disclosure requirements

and corporate

governance rules,

requires the

SEC and securities exchanges to adopt

extensive additional disclosure, corporate

governance and other related rules

and

mandates

further

studies

of

certain

issues

by

the

SEC.

The

SOA

represents

significant

regulation

of

the

accounting

profession and

corporate governance

practices, such

as the

relationship

between a

board of

directors and

management

and between a board of directors and its committees.

As directed

by the

SOA, USCB

Financial Holdings,

Inc.’s principal

executive officer

and principal

financial officer

are

required to certify that the Corporation’s quarterly and

annual reports do not contain any untrue

statement of a material fact.

The rules adopted by

the SEC under the

SOA have several requirements,

including having these

officers certify that:

they

are responsible for establishing, maintaining and regularly evaluating the effectiveness

of our internal control over financial

reporting; they

have made

certain disclosures

to USCB

Financial Holdings,

Inc.’s auditors

and the audit

committee of

the

Board of Directors

about USCB

Financial Holdings,

Inc.’s internal

control over

financial reporting;

and they

have included

information in USCB Financial Holdings,

Inc.’s quarterly and annual

reports about their evaluation

and whether there have

been

changes

in

USCB

Financial

Holdings,

Inc.’s

internal

control

over

financial

reporting

or

in

other

factors

that

could

materially affect USCB Financial Holdings, Inc.’s

internal control over financial reporting.

In March 2020, the SEC issued

a final rule, effective

April 27, 2020, under the

SOA – Amendments to the Accelerated

Filer and

Large Accelerated

Filer Definitions.

As a

result of

the amendments,

certain low

revenue and/or

low public

float

filers, while they remained obligated to provide a

report by management assessing the effectiveness of their internal control

over financial reporting (“ICFR”), were

not required to provide

an attestation report from

their independent auditor assessing

the effectiveness of their ICFR. USCB Financial Holdings,

Inc. meets the amended definition and is not required to provide

an attestation report from its independent

auditor assessing the effectiveness of its ICFR. In

addition, as long it is

an eligible

emerging growth company,

such auditor attestation

requirement will not

apply to USCB

Financial Holdings, Inc.

However,

U.S. Century Bank

remains subject to

independent auditor attestation required

under FDIC regulations

set forth at

12 C.F.R.

§363.3(b).

Item 1A. Risk Factors

This

section

contains

a

description

of

the

material

risk

and

uncertainties

identified

by

management

that

could,

individually or in combination, harm our business, results of

operations, liquidity and financial condition. The risks described

below are

not all

inclusive. We

may face

other risks

that are

not presently

known, or

that we

presently deem

immaterial,

which may also adversely

affect our business, results

of operations, liquidity and

financial condition. If any

of these known

or unknown risks

or uncertainties actually

occur,

our business, results

of operations, liquidity

and financial condition

could

be materially and adversely affected.

Summary of Risk Factors

Our business is subject to

a number of risks that could

cause actual results to differ

materially from those indicated

by

forward-looking statements

made in this

Form 10-K

or presented

elsewhere from

time to time.

These risks

are discussed

more fully in this Item 1A and include, without limitation, the

following:

Risks Related to our Business and Operations

Our

business

operations

and

lending

activities

are concentrated

in

South

Florida,

and

we

are

more

sensitive

to

adverse changes in the local economy than our more geographically

diversified competitors.

The small- to medium-sized businesses

to which we lend may have

fewer resources to weather adverse

business

developments, which may impair a borrower's ability to

repay a loan.

Inflationary pressures and rising prices may affect

our results of operations and financial condition.

Financial challenges

at other

banking institutions

could lead

to depositor

concerns that

spread within

the banking

industry causing disruptive deposit outflows and other destabilizing

results.

Insufficient

liquidity

could

impair

our

ability

to

fund

operations

and

jeopardize

our

financial

condition,

results

of

operations, growth and prospects.

Changes in

U.S. trade policies

and other

global political factors

beyond our

control, including the

imposition of tariffs,

retaliatory

tariffs,

or

other

sanctions,

may

adversely

impact

our

business,

financial

condition

and

results

of

operations.

Our lending business is subject to credit risk, which could

lead to unexpected losses.

The transition from the use of LIBOR may adversely impact the interest rates paid

on certain financial instruments.

Natural

disasters

and

severe

weather

events

in

Florida

could

have

a

material

adverse

impact

on

our

business,

financial condition and operations.

Our business is subject to

interest rate risk and variations

in interest rates may

materially and adversely affect

our

financial performance.

A

failure

or

the

perceived

risk

of

a

failure

to

raise

the

statutory

debt

limit

of

the

U.S.

in

the

future

could

have

a

material adverse effect on our business, financial

condition and results of operations.

Our allowance for credit losses may not be sufficient

to absorb potential losses in our loan portfolio.

Our commercial loan portfolio may expose us to increased

credit risk.

The imposition of further limits

by the bank regulators

on commercial real estate

lending activities could curtail our

growth and adversely affect our earnings.

Our SBA lending program depends on our status as a participant in the SBA's Preferred Lenders Program, and we

face specific risks associated with originating SBA loans

and selling the guaranteed portion thereof.

The SBA may not honor its guarantees if we do not originate

loans in compliance with SBA guidelines.

Global banking is an important part of our business, which creates

increased BSA/AML risk.

We are exposed to risk of environmental liability when

we take title to property.

We are subject to

certain operational risks, including, but

not limited to, customer, employee or

third-party fraud and

data processing system failures and errors.

We face significant

operational risks because

the nature of the

financial services business

involves a high volume

of transactions.

We have several large depositor

Risks Related to Our Tax, Accounting

and Regulatory Compliance

Our ability to

recognize the benefits

of our deferred

tax assets is

dependent on future

cash flows and

taxable income

and may be materially impaired upon significant changes

in ownership of our common stock.

The accuracy of

our financial statements

and related disclosures

could be affected

if the judgments,

assumptions

or estimates used in our critical accounting policies are inaccurate.

As a new public company, we may not efficiently or effectively create an effective internal control environment,

and

any

future

failure

to

maintain

effective

internal

control

over

financial

reporting

could

impair

the

reliability

of

impair

investor

confidence

in

the

accuracy

and

completeness of our financial

reports and our access

of our Class A

common

stock to decline and subject us to regulatory penalties.

We operate in a highly

regulated environment, and the

laws and regulations that

govern our operations, corporate

governance, executive

compensation and

accounting principles, or

changes in them,

or our failure

to comply with

them, could adversely affect us.

We

face

a

risk

of

noncompliance

with

the

Bank

Secrecy

these laws

could lead to a wide variety of sanctions.

Climate change

and related

legislative and

regulatory initiatives

may materially

affect our

business and

results of

operations.

Risks Related to Our Class A Common Stock

Our ability to pay dividends is subject to restrictions.

The market price and trading volume of our Class A common stock may be volatile, which could result in rapid and

substantial losses for our shareholders.

There are

significant restrictions

in our

Articles of

Incorporation

that restrict

the ability

to sell

our capital

stock

to

shareholders that would own 4.95% or more of our stock,

excluding our Significant Investors.

Because

we

are

an

emerging

growth

company

and

because

we

have

decided

to

take

advantage

of

certain

exemptions from various reporting

and other requirements applicable

to emerging growth companies,

our Class A

common stock could be less attractive to investors.

Because

we

have

elected

to

use

the

extended

transition

period

for

complying

with

new

or

revised

accounting

standards for an

“emerging growth company,”

our financial statements

may not be comparable

to companies that

comply with these accounting standards as of the public

company effective dates.

We have existing investors that

own a significant amount of

our common stock whose individual

interests may differ

from yours.

Provisions in our governing documents and Florida

Risks Related to our Business and Operations

Our business

operations and

lending activities

are concentrated

in South

Florida, and

we are

more sensitive

to adverse changes in the local economy than our

more geographically diversified competitors.

Unlike many of

our larger competitors

that maintain significant

operations located

outside of our

market area, most

of

our customers are concentrated in South Florida. In addition, we have

a high concentration of loans secured by real estate

located in

South Florida.

Therefore, our

success depends

upon the

general economic

conditions in

South Florida,

which

may differ from the economic conditions in other areas

of the U.S. or the U.S. generally.

Our real estate

collateral provides

an alternate source

of repayment in

the event

of default by

the borrower;

however,

the value of the collateral may decline during the time the credit is outstanding. The concentration of our loans in the South

Florida area subjects us to

risk that a downturn in the

local economy or recession in

this area could result in

a decrease in

loan originations and increases in delinquencies and foreclosures, which would have a greater negative effect on us than if

our lending were more geographically diversified.

Furthermore, the economic disruption spurred

by the continuing COVID-

19

pandemic

has

particularly

affected

commercial

real

estate

markets.

Additionally,

the

pandemic

has

accelerated

the

adoption of

remote work options,

potentially influencing the

long-term performance of

office properties within

our commercial

real estate portfolio. If we are required

to liquidate our real estate collateral

securing a loan during a period of

reduced real

estate values

to satisfy

the debt,

our earnings

and capital

could be

adversely affected.

Moreover,

since a

large portion

of

our loan portfolio

is secured by

properties located in

South Florida, the occurrence

of a natural

disaster, such as a hurricane,

or a man-made disaster could result in a decline in loan originations,

a decline in the value or the destruction of mortgaged

properties and an increase in

the risk of delinquencies, foreclosures

or loss on loans

originated by us. We may

suffer further

losses due to the decline

in the value of the

properties underlying our mortgage loans, which would

have an adverse impact

on our results of operations and financial condition.

A downturn in the local economy generally may lead to loan losses that are not offset by operations in other markets; it

may also reduce the ability

of our customers to grow

or maintain their deposits with

us. For these reasons, any

regional or

local economic

downturn

that

affects

South Florida,

or existing

or prospective

borrowers

or

depositors

in

South Florida,

could have a material adverse effect on our business,

financial condition and results of operations.

In addition, there are continuing concerns related

to, among other things, the increasing

level of U.S. government debt

and fiscal actions that may be taken to address that debt, price fluctuations

of key natural resources, inflation, the potential

resurgence of economic and political tensions with China,

the continuing war in Ukraine, the

conflict in Gaza and continuing

higher oil prices due to, among other things, Russian supply disruptions resulting from

the ongoing Ukrainian conflict, each

of which may have a destabilizing effect on financial markets and economic activity. Economic pressure on consumers and

overall

economic

uncertainty

may

result

in

changes

in

consumer

and

business

spending,

borrowing

and

saving

habits.

These

economic

conditions

and/or

other

negative

developments

in

the

domestic

or

international

credit

markets

or

economies may significantly

affect the markets

in which we

do business, the

value of our

loans and investments,

and our

ongoing operations, costs and profitability.

The

small-

to

medium-sized

businesses

to

which

we

lend

may

have

fewer

resources

to

weather

adverse

business developments, which may impair a borrower's

ability to repay a loan.

We

target

our

business

development

and

marketing

strategies

primarily

to

serve

the

banking

and

financial

services

needs of SMBs and

the owners and operators of

those businesses. SMBs generally have

fewer financial resources in terms

of capital or

borrowing capacity

than larger entities,

frequently have

smaller market shares

than their competition,

may be

more

vulnerable

to

economic

downturns,

often

need

substantial

additional

capital

to

expand

or

compete,

and

may

experience substantial

volatility in

operating results,

any of

which, individually

or in

the aggregate,

may impair

their ability

as a borrower

to repay a loan.

In addition, the success

of SMBs often

depends on the management

skills, talents and efforts

of a

small group

of key

people, and

the death,

disability or

resignation of

one or

more of

these individuals

could have

an

adverse impact on

the business and

its ability to

repay its loan.

If general economic

conditions negatively impact

the markets

in which we operate

or any of our

borrowers otherwise are affected by adverse

business developments, our SMB borrowers

may be disproportionately affected and their ability to

repay outstanding loans may be adversely affected, which could

have

a material adverse effect on our business, financial

condition and results of operations.

The

continuing

COVID-19

pandemic

has,

and

may

continue

to,

adversely

affect

our

business,

financial

condition, liquidity, capital and results

of operations.

The

COVID-19

pandemic

has

adversely

impacted

the

global

and

national

economy

and

certain

industries

and

geographies in which

our customers operate.

Given its

ongoing and dynamic

nature, it is

difficult to

predict the full

impact

Table of Contents

USCB Financial Holdings, Inc.

2023 10-K

of the continuing

COVID-19 pandemic

on the business

of the Company,

its customers, employees

and third-party

service

providers.

The

extent

of

such

impact

will

depend

on

future

developments,

which

are

highly

uncertain.

Additionally,

the

responses of various governmental and non-governmental authorities

and consumers to the on-going pandemic may have

material long-term effects on

USCB Financial Holdings and our subsidiary

U.S. Century Bank and its customers

which are

difficult to quantify in the near-term or long-term.

Inflationary pressures and rising prices may affect

our results of operations and financial condition.

Since 2021, there have been market indicators of a pronounced rise in inflation and the Federal Reserve raised certain

benchmark interest rates 11 times in

2022 and 2023 in

an effort to combat

inflation.

Although the rate of

inflation moderated

in the fourth

quarter of 2023,

it is still

at levels not seen

for more than

40 years. As

inflation increases and

market interest

rates rise

the value

of our

investment securities,

particularly those

with longer

maturities, decreases,

although this

effect

can be less

pronounced for floating-rate

instruments. In addition,

inflation generally increases

the cost of

goods and services

we use in our business operations, such as electricity and other utilities, which increases our noninterest expenses. Also, a

prolonged period of inflation could cause wages and other of our costs to increase, which could adversely affect our results

of operations and financial condition.

Furthermore, our customers are also

affected by inflation and the

rising costs of goods

and services

used in

their households

and businesses,

which could

have a

negative impact

on their

ability to

repay their

loans with

us. In

addition, SMBs

may be

impacted more

during periods

of high

inflation, as

they are

not able

to leverage

economics of

scale to

mitigate

cost

pressures

compared

to larger

businesses.

Consequently,

the

ability of

our business

customers

to

repay

their

loans

may

deteriorate,

and

in

some

cases

this

deterioration

may

occur

quickly,

which

would

adversely impact our results of operations and financial condition.

Financial

challenges

at

other

banking

institutions

could

lead

to

depositor

concerns

that

spread

within

the

banking industry causing disruptive deposit outflows and other

destabilizing results.

In March 2023, certain specialized banking institutions with elevated concentrations of uninsured deposits experienced

large

deposit

outflows,

resulting

in

the

institutions

being

placed

into

FDIC

receiverships.

In

the

aftermath,

there

was

substantial

market

disruption

and

indications

that

deposit

concerns

could

spread

within

the

banking

industry,

leading to

deposit outflows and other destabilizing results. While the Company does not believe that the

circumstances of these bank

failures, including, in

several cases, the

elevated concentrations of uninsured

deposits, are necessarily indicators

of broader

issues for concern

with all other

banks or with

the banking system itself,

the failures are

likely to continue

to have an

adverse

effect on customer

confidence and the

availability of funding

and liquidity,

as well as possibly

lead to increased regulatory

requirements and costs

and negative reputational

ramifications for

institutions in the

banking industry,

including, possibly,

the Company and its depository subsidiary, U.S. Century Bank.

We will continue to closely monitor the ongoing events

and

volatility

in

the

financial

services

industry,

together

with

responsive

measures

by

the

banking

regulators

to

mitigate

or

manage

the

concerns

of

bank

customers

regarding

FDIC

deposit

insurance

coverage

and

the

safety

and

soundness

of

community

banks.

U.S.

Century

Bank

maintains

a

well-diversified

deposit

base.

At

December

31,

2023,

our

top

15

depositors only

hold 20% of

our total portfolio.

As of December

31, 2023,

45% of

our deposits

are estimated

to be FDIC-

insured. Our public funds

are 14% of total

deposits and are partially

collateralized. The estimated

average account size

of

our

deposit

portfolio

is

$97.0

thousand.

In

addition,

the

Bank

was

considered

a

“well

capitalized”

institution

as

of

December 31, 2023 and 2022.

Insufficient liquidity could

impair our ability to

fund operations and jeopardize

our financial condition,

results

of operations, growth and prospects.

Effective liquidity management is essential for the operation of our business. Although we

have implemented strategies

to maintain

sufficient

and

diverse

sources of

funding

to accommodate

planned,

as well

as unanticipated,

liquidity

needs

(including changes

in assets, liabilities, and

off-balance sheet commitments under various

economic conditions), an inability

to

raise

funds

through

deposits,

borrowings,

the

sale

of

investment

securities

and

other

sources

could

have

a

material

adverse effect

on our

liquidity. Our access

to funding

sources in

amounts adequate to

finance our

activities could

be impaired

by factors that affect us specifically or the financial services

industry in general. Factors that could detrimentally impact

our

access to liquidity sources include a decrease in the level of our business activity due to a market disruption, a decrease in

the borrowing capacity assigned to

our pledged assets by our

secured creditors, competition from other

financial institutions

which could drive up the

costs of deposits or adverse

regulatory action against us. Deterioration in

economic conditions and

the loss of

confidence in financial

institutions may increase

our cost of

funding and limit

our access to

some of our

customary

sources of liquidity,

including, but not

limited to, inter-bank

borrowings and borrowings

from the Federal

Home Loan Bank

of Atlanta, or

the FHLB, and

the Federal Reserve

Bank of Atlanta.

Our ability to

acquire deposits

or borrow

could also be

impaired by

factors that

are not

specific to

us, such

as a

severe disruption

of the

financial markets

or negative

views and

expectations

about the

prospects

for the

financial

services

industry generally

as

a result

of conditions

faced

by banking

organizations

in

the

domestic

and

international

credit

markets.

Any decline

in

available

funding

or cost

of liquidity

could

adversely impact our ability to originate loans, invest in securities, meet our expenses

or fulfill obligations such as repaying

our borrowings or

meeting deposit withdrawal demands,

any of which

could, in turn,

have an adverse

effect on our

business,

financial condition, and results of operations.

Changes in

U.S. trade

policies and

other global

political factors

beyond our

control, including

the imposition

of tariffs, retaliatory tariffs, or other sanctions, may adversely impact our business, financial condition and results

of operations.

There have

been, and

may be

in the

future, changes

with respect

to U.S.

and international

trade policies,

legislation,

treaties and tariffs, embargoes, sanctions and other trade restrictions. Tariffs,

retaliatory tariffs or other trade restrictions on

products

and

materials

that

customers

import

or

export,

or a

trade

war or

other

related governmental

actions

related

to

tariffs,

international

trade

agreements

or

policies

or

other

trade

restrictions

have

the

potential

to

negatively

impact

our

customers' costs, demand

for our products,

or the U.S.

economy or

certain sectors thereof

and, thus, could

adversely impact

our business,

financial condition

and results

of operations.

As a

result of

Russia's invasion

of Ukraine,

the U.S.

imposed,

and is likely to continue to impose material additional, financial and economic sanctions and export controls against certain

Russian organizations and/or individuals, with similar actions either implemented or planned by the European Union ("EU")

and

the

United

Kingdom

(“UK”)

and

other

jurisdictions.

The

U.S.,

the

UK,

and

the

EU

have

each

imposed

packages

of

financial

and

economic

sanctions

that,

in

various

ways,

constrain

transactions

with

numerous

Russian

entities

and

individuals; transactions

in Russian

sovereign debt;

and investment,

trade, and

financing to,

from, or

in certain

regions of

Ukraine. Moreover, actions by Russia, and any

further measures taken by the

U.S. or its allies,

could have negative impacts

on regional and global

financial markets and economic

conditions. To the extent changes in the

global political environment,

including the

continuing war

in Ukraine

and the

continued heightened

tensions between

Russia and

the U.S.,

NATO,

the

EU and the

UK, as well

as the conflict

in Gaza, have

a negative impact

on us or

on the markets

in which we

operate, our

business, results of operations and financial condition could be

materially and adversely impacted.

Our lending business is subject to credit risk, which

could lead to unexpected losses.

Our

primary

business

involves

making

loans

to

customers.

The

business

of

lending

is

inherently

risky

because

the

principal or

interest on

the loan

may not

be repaid

timely or

at all

or the

value of

any collateral

securing the

loan may

be

insufficient to

cover our

outstanding exposure.

These risks

may be affected

by the

strength or

weakness of

the particular

borrower's business sector

and local, regional and

national market and

economic conditions. Many

of our loans are

made

to SMBs that may be

less able to withstand

competitive, economic and financial

pressures than larger borrowers.

Our risk

management practices,

such as

monitoring the

concentration of

our loans

within specific

industries in

which we

lend and

concentrations with individual borrowers

or related borrowers, and

our credit approval

practices, may not adequately

reduce

credit risk. In addition, there are risks inherent in making any loan, including

risks relating to proper loan underwriting, risks

resulting from

changes in

economic and

industry conditions,

risks inherent

in dealing

with individual

borrowers, including

the risk that a borrower may not provide

information to us about their business

in a timely manner,

may present inaccurate

or incomplete information to us, may lack a U.S. credit history,

or may leave the U.S. without fulfilling their loan obligations,

leaving us with

little recourse

to them personally,

and/or risks

relating to the

value of

collateral. In

order to

manage credit

risk successfully,

we must,

among other

things, maintain

disciplined and

prudent underwriting

standards and

ensure that

our lenders follow those standards. The weakening of

these standards for any reason, such as an

attempt to attract higher

yielding loans,

a lack

of discipline

or diligence

by our

employees in

underwriting and

monitoring loans,

the inability

of our

employees to adequately adapt

policies and procedures to

changes in economic or

any other conditions affecting borrowers

and the quality

of our loan portfolio,

may result in loan

defaults, foreclosures and additional charge-offs and

may necessitate

that we significantly increase our allowance for credit losses, each of which could adversely affect our net income. A failure

to effectively

manage

credit risk

associated

with

our loan

portfolio could

lead to

unexpected

losses and

have a

material

adverse effect on our business, financial condition

and results of operations.

The

transition

from

the

use

of

LIBOR

may

adversely

impact

the

interest

rates

paid

on

certain

financial

instruments.

LIBOR was used as a reference rate for certain of the Corporation’s adjustable-rate loans and bonds. In 2017, the U.K.

Financial Conduct

Authority,

which regulates

LIBOR,

announced that

the publication

of LIBOR

would not

be guaranteed

beyond 2021. In December 2020, the

administrator of LIBOR announced its intention to

(i) cease the publication of the

one-

week and two-month

U.S. dollar LIBOR

after December 31,

2021, and (ii)

cease the publication

of all other

tenors of U.S.

dollar LIBOR (one, three, six and 12 month LIBOR) after

June 30, 2023.

There are ongoing efforts to establish an alternative

reference rate. The Federal Reserve Board, in conjunction with

the

Alternative

Reference

Rates

Committee,

a

steering

committee

comprised

of

large

U.S.

financial

institutions,

supports

replacing LIBOR with SOFR, a new index calculated

by short-term repurchase agreements backed by

Treasury securities.

The Bank adopted SOFR as its preferred benchmark as

an alternative to LIBOR for use in new contracts in 2023.

While

the

Adjustable

Interest

Rate

(LIBOR)

Act

and

implementing

regulations

will

help

to

transition

legacy

LIBOR

contracts to a new benchmark rate, the

substitution of SOFR for LIBOR may

have potentially significant economic impacts

on parties to affected

contracts. SOFR is

different from LIBOR

in that it is

a retrospective-looking secured

rate rather than

a forward-looking

unsecured rate.

Additionally,

while SOFR

appears to

be the

preferred replacement

rate for

LIBOR, it

is

not

possible

to

predict

whether

SOFR

will

ultimately

prevail

in

market

as

the

definitive

replacement

for

LIBOR.

Uncertainty

as

to

the

nature

of

alternative

reference

rates,

and

as

to

potential

changes

or

other

reforms

related

to

the

Natural disasters and severe weather events in Florida

could have a material adverse impact on our

business,

financial condition and operations.

Our

operations

and

our

base

are

primarily

located

in

South

Florida.

is

vulnerable

to

such

as

which

can

have

property damage

to businesses

and residences,

depress

the value of property serving as collateral for our loans, force the relocation of residents, and

significantly disrupt economic

activity in the region.

We cannot

predict the

extent of

damage that

may result

from such

adverse weather

events, which

will depend

on a

variety of factors that are beyond our control,

including, but not limited to, the

severity and duration of the event,

the timing

and level

of government

responsiveness, the

pace of

economic recovery

and availability

of insurance

to cover

losses. In

addition,

the

nature,

frequency

and

severity

of

these

adverse

weather

events

and

other

natural

disasters

may

be

exacerbated by climate change. If a significant adverse weather event or other natural disaster were to occur, it could have

a materially adverse impact

on our financial

condition, results of operations

and our business, as

well as potentially

increase

our exposure to credit and liquidity risks.

Our business is subject to

interest rate risk, and variations in

interest rates may materially and adversely

affect

our financial performance.

Changes in the

interest rate environment

may reduce our

profits. It is

expected that our

primary source of

income will

continue to be from

the differential or

"spread" between the

interest earned on

loans, securities and

other interest-earning

assets, and the interest paid on

deposits, borrowings and other interest-bearing liabilities. Net

interest spreads are affected,

in part, by the

difference between the maturities and repricing characteristics of

interest-earning assets and interest-bearing

liabilities. Changes

in market

interest rates

generally affect

loan volume,

loan yields,

funding sources

and funding

costs.

Our

net interest

spread

depends

on

many

factors

that

are partly

or completely

out

of our

control,

including

competition,

general economic

conditions, and

federal economic

monetary and

fiscal policies,

and in particular,

the Federal

Reserve's

policy determinations with respect to interest rates.

During 2022

and 2023,

the Federal

Open Market

Committee of

the Federal

Reserve (the

“FOMC”) increased

certain

benchmark interest rates to reduce the rate of inflation to the extent

necessary to reduce inflation to the rate that the FOMC

believes is appropriate. Since March 2022, the FOMC has increased the federal funds rate by

500 basis points. All of these

increases were expressly made in response to inflationary pressures.

Recently the FOMC has paused increases in certain

benchmark interest rates and may consider decreases in such

benchmark rates at some point during 2024. However, there

can be no

assurances as to

any future FOMC

action, including whether

it decreases

the federal funds

rate or implements

further increases.

While an increase in

interest rates may increase

our weighted average

loan yield, it may

adversely affect the

ability of

certain borrowers

with variable rate

loans to pay

the contractual

interest and principal

due to us.

Following an

increase in

interest rates, our

ability to maintain

a positive net

interest spread is

dependent on our ability

to increase our

loan offering

rates, replace

loans that

mature and

repay or

that prepay

before maturity

with new

originations at

higher rates,

minimize

increases on

our deposit

rates, and maintain

an acceptable level

and composition of

funding. We cannot

provide assurances

that we will be

able to increase

our loan offering

rates and continue

to originate loans

due to the competitive

landscape in

which we operate. Additionally, we cannot provide

assurances that we can minimize

the increases in our

deposit rates while

maintaining

an

acceptable

level

of

deposits.

Due

to

competitive

pressures

in

2023,

we

increased

the

rates

paid

on

our

interest-bearing deposits such that

our weighted average cost

of deposits increased from

0.62% for 2022

to 3.04% for

2023.

Finally,

we

cannot

provide

any

assurances

that

we

can

maintain

our

current

levels

of

noninterest-bearing

deposits

as

customers may seek higher-yielding products due to the

increased interest rates being paid on deposits currently.

Accordingly,

changes

in

levels

of

interest

rates

could

materially

and

adversely

affect

our

net

interest

margin,

asset

quality, loan origination

volume, average loan portfolio balance, liquidity,

and overall profitability.

A failure or the perceived

risk of a failure to raise

the statutory debt limit

of the U.S. in the future

could have a

material adverse effect on our business, financial

condition and results of operations

.

Ongoing

U.S.

debt

ceiling

and

budget

deficit

concerns

have

increased

the

possibility

of

additional

credit-rating

downgrades

and

economic

slowdowns,

or

a

recession

in

the

United

States.

Although

U.S.

lawmakers

have

passed

legislation

in the

past to

raise the

federal debt

ceiling

on multiple

occasions,

including

the most

recent

increase

in June

2023, ratings agencies have lowered or threatened to lower the long-term sovereign credit rating on the United States. The

impact of this or any further

downgrades to the U.S. government’s

sovereign credit rating or its

perceived creditworthiness

could adversely affect the U.S. and global financial markets and economic conditions. Absent further quantitative easing by

the Federal

Reserve,

these

developments

could

cause

interest rates

and borrowing

costs

to rise,

which

may negatively

impact our

ability to

access

the debt

markets on

favorable terms.

In addition,

disagreement over

the federal

budget has

caused the U.S. federal government to shut down for periods of time. Continued adverse

political and economic conditions

could have a material adverse effect on our business,

financial condition and results of operations.

Our allowance for credit losses may not be sufficient

to absorb potential losses in our loan portfolio.

We

maintain

an

allowance

for

credit

losses

that

represents

management's

judgment

of

probable

losses

and

risks

inherent in our loan portfolio.

The level of the allowance

reflects management's continuing

evaluation of general economic

conditions,

present

political

and

regulatory

conditions,

diversification

and

seasoning

of

the

loan

portfolio,

historic

loss

experience, identified credit

problems, delinquency levels

and adequacy of

collateral. Determining the

appropriate level of

our

allowance

for

credit

losses

involves

a

degree

of

subjective

judgment

and

requires

management

to

make

significant

estimates of and assumptions regarding current credit risks

and future trends, all of which may undergo material changes.

Inaccurate

management

assumptions,

deterioration

of

economic

conditions

affecting

borrowers,

new

negative

information

regarding

existing

loans,

identification

of

additional

problem

loans

or deterioration

of existing

problem

loans,

and

other

factors

(including

third-party

review

and

analysis),

both

within

and

outside

of

our

control,

may

require

us

to

increase our allowance for

credit losses. In addition,

our regulators, as an

integral part of their

periodic examinations, review

our methodology for calculating, and

the adequacy of, our allowance

for credit losses and may

direct us to make additions

to the allowance

based on their

judgments about

information available to

them at the

time of their

examination. Further,

if

actual charge-offs in future

periods exceed the

amounts allocated to

our allowance for

credit losses, we

may need additional

provisions for credit losses to restore

the adequacy of our allowance for

credit losses. Finally, the measure of our allowance

for credit losses depends on the

adoption and interpretation of accounting

standards. The Financial Accounting

Standards

Board, or FASB, issued a new credit

impairment model, the Current Expected Credit Loss,

or CECL model, which became

applicable

to

us

on

January

1,

2023.

CECL

requires

financial

institutions

to

estimate

and

develop

a

provision

for

credit

losses over the lifetime of the loan at origination, as opposed to reserving for incurred or probable

losses up to the balance

sheet date. Under the CECL

model, expected credit deterioration

will be reflected in the

income statement in the

period of

origination or acquisition of a loan,

with changes in expected credit losses

due to further credit deterioration or

improvement

reflected in

the periods

in which

the expectation

changes. Accordingly,

implementation of

the CECL

model could

require

financial institutions, like us, to

increase our allowances for

credit losses from levels in place

prior to the implementation of

CECL. As a result of the initial implementation of CECL,

we incurred as of January 1, 2023 a $1.1

million cumulative effect

of the adoption

of CECL. Moreover,

the CECL model

may create more volatility

in our level

of allowance for

credit losses.

If we

are required

to materially

increase our

level of

allowance for

credit losses

for any

reason, such

increase could

adversely

affect our business, prospects, cash flow,

liquidity, financial

condition and results of operations.

Our commercial loan portfolio may expose us to increased

credit risk.

Commercial business

and real

estate loans

generally have

a higher

risk of

loss because

loan balances

are typically

larger

than

residential

real

estate

and

consumer

loans

and

repayment

is

usually

dependent

on

cash

flows

from

the

borrower’s business or the

property securing the loan. Our

commercial business loans are primarily made

to small business

and middle market customers. These loans typically

involve repayment that depends upon income

generated, or expected

to be generated, by the property securing the loan and/or

by the cash flow generated by the business borrower and

may be

adversely affected by changes in the economy or

local market conditions. These loans expose a

lender to the risk of having

to liquidate the collateral securing

these loans at times when

there may be significant fluctuation

of commercial real estate

values or to the

risk of inadequate cash flows to

service the commercial loans. Unexpected deterioration in

the credit quality

of our

commercial business

and/or real

estate loan

portfolio could

require us

to increase

our allowance

for credit

losses,

which would

reduce our

profitability and

could have

an adverse

effect on

our business,

financial condition,

and results

of

operations.

Commercial construction loans generally

have a higher risk of

loss due to the assumptions

used to estimate the value

of property

at completion

and the

cost of

the project,

including interest.

It can

be difficult

to accurately

evaluate the

total

Table of Contents

28

USCB Financial Holdings, Inc.

2023 10-K

funds required

to complete

a project,

and construction

lending often

involves the

disbursement

of substantial

funds with

repayment dependent, in large part, on the success of the ultimate project rather than the ability of a borrower or guarantor

to repay the loan from sources other than the subject project. If the assumptions and estimates are inaccurate, the value of

completed property

may fall

below the

related loan

amount. If we

are forced to

foreclose on

a project

prior to

completion,

we may

be

unable

to

recover

the

entire

unpaid

portion

of the

loan,

which

would

lead

to

losses.

In

addition,

we

may

be

required to fund additional amounts to complete a project,

incur taxes, maintenance and compliance costs for

a foreclosed

property and

may have

to hold

the property

for an

indeterminate

period of

time, any

of which

could adversely

affect

our

business, prospects, cash flow,

liquidity, financial

condition and results of operations.

The imposition of

further limits by the

bank regulators on commercial

real estate lending activities

could curtail

our growth and adversely affect our earnings.

The FDIC, the Federal Reserve

and the Office of

the Comptroller of the

Currency have promulgated joint

guidance on

sound risk management practices for financial institutions with concentrations in commercial real estate lending. Under this

guidance,

a financial

institution

that,

like

us,

is actively

involved

in

commercial

real

estate

lending should

perform

a risk

assessment to identify

concentrations. Regulatory

guidance on concentrations

in commercial real

estate lending provides

that a bank’s commercial real estate lending exposure could

receive increased supervisory scrutiny where total commercial

real estate

loans, including

loans secured

by multi-family

residential

properties, owner-occupied

and nonowner-occupied

investor real estate, and

construction and land loans, represent 300%

or more of an

institution’s total risk-based capital, and

the outstanding balance of the commercial real estate loan portfolio has increased by

50% or more during the preceding 36

months.

At

December

31,

2023,

our

total

commercial

investor

real

estate

loans,

including

loans

secured

by

apartment

buildings, commercial real estate, and construction

and land loans represented 384% of the Bank’s

total risk-based capital

and the growth in the commercial real estate portfolio exceeded 50% over

the preceding 36 months. The particular focus of

the guidance is on exposure to commercial

real estate loans that are dependent

on the cash flow from the real estate

held

as collateral and that

are likely to be

at greater risk

to conditions in the

commercial real estate

market (as opposed

to real

estate collateral held as a secondary source of repayment

or as an abundance of caution). The purpose

of the guidance is

to guide institutions in developing risk management practices and capital

levels commensurate with the level and nature of

real estate

concentrations.

Management has

established a

commercial real

estate lending

framework

to monitor

specific

exposures and limits by

types within the commercial

real estate portfolio and

takes appropriate actions, as necessary. While

we believe

we have

implemented policies and

procedures with

respect to

our commercial

real estate

loan portfolio

consistent

with this

guidance, the

FDIC, the

Bank’s primary

federal regulator,

could require

us to

implement additional

policies and

procedures pursuant to their interpretation

of the guidance that may result

in additional costs to us. In addition,

If the FDIC

were to impose restrictions on the amount

of commercial real estate loans we can

hold in our portfolio, our earnings would

be adversely affected.

Our

SBA

lending

program

is dependent

upon

the

federal

government

and

our status

as

a participant

in the

SBA's Preferred

Lenders Program,

and we

face specific

risks associated

with originating

SBA loans

and selling

the guaranteed portion thereof.

We

have

been

approved

by

the

SBA

to

participate

in

the

SBA's

Preferred

Lenders

Program.

As

an

SBA

Preferred

Lender,

we enable

our clients

to obtain

SBA loans

without being

subject to

the potentially

lengthy SBA

approval process

necessary

for

lenders

that

are

not

SBA

Preferred

Lenders.

The

SBA

periodically

reviews

the

lending

operations

of

participating

lenders

to

assess,

among

other

things,

whether

the

lender

exhibits

prudent

risk

management.

When

weaknesses are identified, the SBA may request corrective actions

or impose enforcement actions, including revocation of

the lender's

Preferred Lender

status. If

we lose

our status

as an

SBA Preferred

Lender,

we may

lose some

or all

of our

customers to

lenders who

are SBA

Preferred Lenders,

which could

adversely affect

our business,

financial condition

and

results of operations.

We generally sell the guaranteed

portion of our SBA 7(a) loans

in the secondary market. These sales

have resulted in

both premium income for us

at the time of

sale and created a stream

of future servicing income. There

can be no assurance

that we will be able to continue originating these loans, that a secondary market for these loans will continue to exist or that

we will continue to realize

premiums upon the sale of

the guaranteed portion of

these loans. When we sell

the guaranteed

portion of our SBA 7(a) loans, we incur credit risk on the non-guaranteed portion of the loans, and if a customer defaults on

the non-guaranteed portion of a loan, we share any loss

and recovery related to the loan pro-rata with the SBA.

The laws, regulations and

standard operating procedures

that are applicable to

SBA loan products may

change in the

future. We

cannot predict

the effects

of these

changes on

our business

and profitability.

Because government

regulation

greatly

affects

the

business

and

financial

results

of

all

commercial

banks

and

bank

holding

companies,

especially

our

organization, changes in the laws, regulations

and procedures applicable to SBA loans

could adversely affect our ability

to

operate profitably.

In addition, the

aggregate amount of

SBA 7(a) and 504

loan guarantees by the

SBA must be approved

each fiscal year by the federal

government. We cannot predict

the amount of SBA 7(a)

loan guarantees in any given fiscal

Table of Contents

29

USCB Financial Holdings, Inc.

2023 10-K

year. If the federal government were to reduce the amount of SBA loan guarantees, such reduction

could adversely impact

our SBA lending

program, including making and

selling the guaranteed portion

of fewer SBA

7(a) and 504

loans. In addition,

any default by

the U.S. government

on its obligations

or any prolonged

government shutdown

could, among

other things,

impede our ability to originate

SBA loans or sell such loans

in the secondary market, which

could materially and adversely

affect our business, financial condition and results

of operations.

The SBA may not honor its guarantees if we do not originate

loans in compliance with SBA guidelines

.

SBA lending programs

typically guarantee

75.0% of the

principal on

an underlying

loan. If the

SBA establishes

that a

loss on

an

SBA guaranteed

loan

is attributable

to significant

technical

deficiencies

in the

manner

in which

the loan

was

originated,

funded

or serviced

by us,

the

SBA may

seek

recovery

of

the

principal

loss

related

to

the

deficiency

from

us

notwithstanding that a portion of the loan was

guaranteed by the SBA, which could adversely

affect our business, financial

condition and results of

operations. While we

follow the SBA's underwriting

guidelines, our ability to

do so depends on the

knowledge and diligence of our employees

and the effectiveness of controls

we have established. If our employees

do not

follow

the

SBA

guidelines

in

originating

loans

and

if

our

loan

review

and

audit

programs

fail

to

identify

and

rectify

such

failures, the

SBA may

reduce or,

in some

cases, refuse

to honor

its guarantee

obligations and

we may

incur losses

as a

result.

Global banking is an important part of our business, which

creates increased BSA/AML risk.

As our

business

model

includes

correspondent

services

to banks

in Latin

America

and the

Caribbean,

these

cross-

border

correspondent

banking

relationships

pose

unique

risks

because

they

create

situations

in

which

a

U.S.

financial

institution will be

handling funds from

a financial institution

in Latin America

and the Caribbean

whose customers may

not

be transparent to us. Moreover, many foreign financial institutions, including

in Latin America and the Caribbean where our

correspondent banking

services

are located,

are not

subject to

the same

or similar

regulatory

guidelines

as U.S.

banks.

Accordingly,

these

foreign

institutions

may

pose

higher

money

laundering

risk

to

their

respective

U.S.

bank

correspondent(s). Because

of the

large amount

of funds,

multiple transactions,

and our

potential lack

of familiarity

with a

foreign correspondent financial institution's customers, these customers may

be able to more

easily conceal the source and

use of

illicit funds.

Consequently,

we may

have a

higher

risk

of non-compliance

with the

BSA

and

other

AML rules

and

regulations

due

to

our

correspondent

banking

relationships

with

foreign

financial

institutions.

Additionally,

international

private banking

places additional

pressure on

our policies,

procedures and

systems for

complying with

the Bank

Secrecy

Act of 1970,

as amended, or BSA,

and other anti-money laundering,

or AML, statutes

and regulations as

well as the

recently

enacted Corporate

Transparency

Act. Our failure

to strictly

adhere to the

terms and requirements

of our OFAC

license or

our

failure

to

adequately

manage

our

BSA/AML

compliance

risk

in

light

of

our

correspondent

banking

relationship

with

foreign financial institutions and international private banking could result

in regulatory or other actions being taken against

us, which could significantly increase our compliance costs

and materially and adversely affect our results

of operations.

We may not recover all amounts that are contractually

owed to us by our borrowers.

We are

dependent on

the collection

of loan

principal, interest,

and fees

to partially

fund our

operations. A

shortfall in

collections and proceeds may impair our ability to fund

our operations or to repay our existing debt.

When

we

lend

funds,

commit

to

fund

a

loan

or

enter

into

a

letter

of

credit

or

other

credit-related

contract

with

a

counterparty, we incur credit risk. The

credit quality of our

portfolio can have a

significant impact on our

earnings. We expect

to experience charge-offs and delinquencies on our loans

in the future. Many borrowers have been negatively impacted by

the ongoing COVID-19 pandemic and

related economic consequences, and

may continue to be similarly or

more severely

affected in the future.

Our customers' actual operating

results may be worse than

our underwriting contemplated

when we

originated the loans, and in these circumstances, we could incur substantial impairment or loss of

the value on these loans.

We may fail to identify problems

because our customer did not

report them in a timely manner

or, even if the

customer did

report the problem, we may fail to address it quickly enough or at all, or some loans, due to market circumstances, may not

be able

to be

fully rehabilitated.

Even if

customers provide

us with

full and

accurate disclosure

of all

material information

concerning their businesses,

we may misinterpret

or incorrectly analyze

this information. Mistakes

may cause us

to make

loans that we otherwise

would not have made or

to fund advances that we otherwise

would not have funded, either

of which

could result in losses

on loans, or necessitate

that we significantly

increase our allowance

for loan and

lease losses. As

a

result, we could

suffer loan

losses and have

non-performing loans,

which could have

a material adverse

effect on our

net

earnings and results of operations and financial condition, to the extent the losses exceed our allowance for loan and lease

losses.

Some of our

loans are secured

by a lien

on specified collateral

of the borrower

and we may

not obtain or

properly perfect

our liens or the value of the collateral securing any particular loan may not be sufficient to protect us from suffering a partial

or complete

loss

if the

loan becomes

non-performing

and we

proceed to

foreclose

on or

repossess

the collateral.

With

respect to loans that we originate for condominium or homeowners'

associations, these loans are primarily secured by and

rely upon the

cash flow received

by the Associations

from payments received

from their property

owners, as well

as cash

on hand.

These Associations

rely upon

payments received

from their

property owners

in order

to perform

on these

loans

and for

the

loan collateral.

Accordingly,

our ability

to recover

amounts

on non-performing

loans made

to Associations

is

dependent upon the

Association having sufficient cash on

hand for repayment of

the loan and/or having

the ability to impose

assessments on its property owners, some of whom may not have the ability to pay such assessments. In such events, we

could

suffer

loan

losses,

which

could

have

a

material

adverse

effect

on

our

net

earnings,

allowance

for

loan

and

lease

losses, financial condition, and results of operations.

Non-performing

assets

take

significant

time

to

resolve

and

adversely

affect

our

results

of

operations

and

financial condition, and could result in further losses in

the future.

Non-performing assets adversely

affect our net

income in

various ways. We

do not

record interest income

on nonaccrual

loans or other

real estate

owned (“OREO”),

thereby adversely

affecting our

net income

and returns on

assets and

equity,

increasing our loan administration costs and adversely

affecting our efficiency ratio. When

we take collateral in foreclosure

and similar proceedings, we are

required to mark the collateral to

its then-fair market value, which may

result in a loss. Non-

performing loans

and OREO

also increase our

risk profile

and the level

of capital

our regulators

believe is appropriate

for

us to

maintain in

light of

such risks.

The resolution

of non-performing

assets requires

significant time

commitments from

management and can

be detrimental to

the performance

of their other

responsibilities. If

we experience increases

in non-

performing

loans

and

non-performing

assets,

our

net

interest

income

may

be

negatively

impacted

and

our

loan

administration costs could increase, each of which could have an adverse effect on our net income and related ratios, such

as return on assets and equity.

We engage in

lending secured by

real estate and

may foreclose on

the collateral and

own the underlying

real

estate,

subjecting

us

to

the

costs

and

potential

risks

associated

with

the

ownership

of

real

property,

including

exposure

to

environmental

liability,

or

consumer

protection

initiatives

or

changes

in

state

or

federal

law

may

substantially raise the cost of foreclosure or prevent

us from foreclosing at all.

Since we

originate

loans secured

by real

estate, we

may have

to foreclose

on the

collateral

property

to recover

our

investment and may thereafter own and operate such property,

in which case we would be exposed to the risks inherent in

the

ownership

of

real

estate.

The

amount

that

we,

as

a

mortgagee,

may

realize

after

a

foreclosure

depends

on

factors

outside of our

control, including,

but not limited

to, general or

local economic conditions,

environmental cleanup

liabilities,

various assessments

relating to

the ownership

of the property,

interest rates, real

estate tax rates,

operating expenses

of

the

mortgaged

properties,

our

ability

to

obtain

and

maintain

adequate

occupancy

of

the

properties,

zoning

laws,

governmental and

regulatory rules,

and natural disasters.

Our inability

to manage

the amount

of costs

or size

of the risks

associated with

the ownership

of real

estate, or

write-downs in

the value

of OREO,

could have

an adverse

effect on

our

business, financial condition, and results of operations.

Additionally,

consumer protection initiatives

or changes in state

or federal law may

substantially increase the time

and

expenses associated

with the

residential foreclosure

process or

prevent us

from foreclosing

at all.

A number

of states

in

recent

years

have

either

considered

or

adopted

foreclosure

reform

laws

that

make

it

substantially

more

difficult

and

expensive for

lenders to

foreclose on

residential properties

in default.

Furthermore, federal

regulators have

prosecuted a

number of

mortgage servicing

companies for

alleged consumer

law violations.

If new

state or

federal laws

or regulations

are ultimately enacted

that significantly raise

the cost of residential

foreclosures or raise

outright barriers, they

could have

an adverse effect on our business, financial condition,

and results of operations.

We are exposed to risk of environmental liability

when we take title to property.

A

significant

portion

of

our

loan

portfolio

is

secured

by

real

estate,

and

we

could

become

subject

to

environmental

liabilities with respect

to one or

more of these

properties, or with

respect to properties that

we own in

operating our business.

During the ordinary course of business,

we may foreclose on and take title to

properties securing defaulted loans. In

doing

so, there is

a risk that

hazardous or toxic

substances could

be found on

these properties. If

hazardous conditions

or toxic

substances are found

on these properties,

we may be

liable for remediation

costs, as well

as for personal

injury and property

damage, civil

fines and

criminal penalties

regardless

of when

the hazardous

conditions or

toxic substances

first affected

any particular property.

The costs associated with investigation or

remediation activities could be substantial.

In addition, if

we are the owner or former owner

of a contaminated site, we may be

subject to common law claims by

third parties based

on damages and

costs resulting

from environmental

contamination emanating

from the

property.

If we become

subject to

significant environmental liabilities, our business, financial condition

and results of operations could be adversely affecte

d.

We

are

subject

to

certain

operational

risks,

including,

but

not

limited

to,

customer,

employee

or

third-party

fraud and data processing system failures and errors.

Employee errors and employee or

customer misconduct could subject us

to financial losses or

regulatory sanctions and

seriously harm our reputation. Misconduct by our employees could include hiding unauthorized

activities from us, improper

or unauthorized activities on behalf of our customers or improper use of confidential information. It is not

always possible to

prevent employee

errors and

misconduct, and

the precautions we

take to

prevent and

detect this

activity may

not be

effective

in all cases. Employee errors could also subject us

to financial claims for negligence.

We have

implemented a

system of

internal controls

designed to

mitigate operational

risks, including

data processing

system failures

and errors

and customer

or employee

fraud, as

well as

insurance

coverage

designed to

protect us

from

material

losses

associated

with

these

risks,

including

losses

resulting

from

any

associated

business

interruption.

If

our

internal controls fail

to prevent or

detect an

occurrence, or if

any resulting loss

is not

insured or exceeds

applicable insurance

limits, it could adversely affect our business,

prospects, cash flow, liquidity,

financial condition and results of operations.

We

also

rely

on

the

integrity

and

security

of

a

variety

of

third

party

processors,

payment,

clearing

and

settlement

systems, as well

as the various

participants involved

in these systems,

many of which

have no direct

relationship with us.

Failure

by

these

participants

or

their

systems

to

protect

our

customers'

transaction

data

may

put

us

at

risk

for

possible

losses due

to fraud

or operational

disruption. At

the date

of this

Annual Report

Form 10-K,

there is

no knowledge or

indication

that customer

sensitive information

was compromised

as a

result of

third parties

system vulnerabilities,

but management

continues to monitor developments and vendor communications.

When we originate loans, we rely

heavily upon information supplied by third parties,

including the information contained

in credit

applications, property

appraisals, title

information, equipment

pricing and

valuation and

employment and

income

documentation, in deciding which loans we will originate, as well as the terms of those loans. If any of the information upon

which

we

rely

is

misrepresented,

either

fraudulently

or

inadvertently,

and

the

misrepresentation

is

not

detected

prior

to

funding,

the value

of

the

loan may

be significantly

lower

than expected,

or we

may

fund a

loan that

we

would not

have

funded or

on terms

that do

not comply

with our

general underwriting

standards. Whether

a misrepresentation

is made

by

the applicant, the borrower,

one of our employees or another

third party,

we generally bear the risk of

loss associated with

the misrepresentation. A loan

subject to a material

misrepresentation is typically

unsellable or subject to

repurchase if it

is

sold prior to detection of the

misrepresentation. The sources of

the misrepresentations are often

difficult to locate, and

it is

often difficult

to recover

any

of the

resulting monetary

losses we

may suffer,

which

could

adversely

affect

our business,

financial condition and results of operations.

We

face

significant

operational

risks

because

the

nature

of

the

financial

services

business

involves

a

high

volume of transactions

.

We

operate

in

diverse

markets

and

rely

on

the

ability

of

our

employees

and

systems

to

process

a

high

number

of

transactions. Operational

risk is

the risk of

loss resulting from

our operations,

including but not

limited to, the

risk of fraud

by employees or

persons outside

the Company,

the execution

of unauthorized

transactions by

employees, errors

relating

to transaction

processing and technology, breaches of

our internal

control systems and

compliance requirements. Insurance

coverage may

not be available

for such

losses, or

where available, such

losses may

exceed insurance

limits. This

risk of

loss

also

includes

potential

legal

actions

that

could

arise

as

a

result

of

operational

deficiencies

or

as

a

result

of

non-

compliance with applicable regulatory standards,

adverse business decisions or their

implementation, or customer attrition

due to

potential adverse publicity. In the

event of a

breakdown in our

internal control systems,

improper operation of

systems

or improper employee actions, we could suffer financial

loss, face regulatory action, and/or suffer damage to

our reputation.

We have several

large depositor relationships,

the loss of which

could force us to

fund our business

through

more expensive and less stable sources.

Withdrawals of deposits by any

one of our largest depositors

could force us to

rely more heavily on more

expensive and

less stable funding sources.

Consequently,

the occurrence of any

of these events could

have a material adverse

effect on

our business, financial condition and results of operations.

Our securities portfolio performance in difficult market conditions could have adverse effects on

our results of

operations

.

Unrealized losses on

investment securities result from

changes in credit

spreads and liquidity

issues in the

marketplace,

along

with

changes

in

the

credit

profile

of

individual

securities

issuers.

Under

GAAP,

we

are

required

to

review

our

investment

portfolio

periodically

for

the

presence

of credit

losses

of

our securities,

taking

into consideration

current

and

future

market

conditions,

the

extent

and

nature

of

changes

in

fair

value,

issuer

rating

changes

and

trends,

earnings, current

analysts’ evaluations,

our ability

and intent

to hold

investments until

a recovery

of fair

value, as

well as

other factors. Adverse developments with respect to one or more of

the foregoing factors may require us to deem particular

securities to be impaired, with the credit-related portion of

the reduction in the value recognized as a

charge to our earnings

through an allowance. Subsequent valuations,

in light of factors prevailing at that

time, may result in significant changes

in

the values of these securities in future periods.

Any of these factors could require us to

recognize further impairments in the

value of our securities portfolio, which may have an adverse

effect on our results of operations in future periods.

We may not

effectively execute

on our expansion

strategy, which

may adversely affect

our ability to

maintain

our historical growth and earnings trends.

Our

primary

expansion

strategy

focuses

on

organic

growth,

supplemented

by

potential

acquisitions

of

financial

institutions and

banking teams;

however,

we may

not be

able to

successfully execute

on these

aspects of

our expansion

strategy,

which

may

cause

our

future

growth

rate

to

decline

below

our

recent

historical

levels,

or

may

prevent

us

from

growing at

all. More

specifically,

we may

not be able

to generate

sufficient new

loans and

deposits within

acceptable risk

and

expense

tolerances

or

obtain

the

personnel

or

funding

necessary

for

additional

growth.

Various

factors,

such

as

economic conditions

and competition

with other financial

institutions, may impede

or restrict the

growth of our

operations.

Further, we may be unable to attract

and retain experienced bankers, which could

adversely affect our growth. The success

of our strategy also depends on our ability to manage our growth effectively,

which in turn depends on a number of factors,

including

our

ability

to

adapt

our

credit,

operational,

technology,

risk

management,

internal

controls

and

governance

infrastructure to accommodate expanded operations.

Even if we are successful in continuing our growth,

such growth may

not offer the same

levels of potential profitability,

and we may not

be successful in

controlling costs and maintaining

asset

quality in the

face of that

growth. Accordingly,

our inability

to maintain

growth or

to effectively

manage growth

could have

an adverse effect on our business, financial condition

and results of operations.

New lines of business, products, product enhancements

or services may subject us to additional risk.

From time to time, we

may implement new lines

of business or offer

new products and product

enhancements as well

as new

services within

our existing

lines of

business. There

are substantial

risks and

uncertainties associated

with these

efforts. In

developing, implementing

or marketing new

lines of business,

products, product

enhancements or

services, we

may invest significant time and

resources. We may underestimate the appropriate level

of resources or expertise

necessary

to

make

new

lines

of

business

or

products

successful

or

to

realize

their

expected

benefits.

We

may

not

achieve

the

milestones

set

in

initial

timetables

for

the

development

and

introduction

of

new

lines

of

business,

products,

product

enhancements or services, and price

and profitability targets may not

prove feasible. External factors, such

as compliance

with regulations, competitive

alternatives and shifting

market preferences, may

also impact the

ultimate implementation of

a new line of business or offerings of new products, product

enhancements or services. Any new line of business,

product,

product enhancement or service could have a significant impact on the effectiveness of our system of internal controls. We

may also

decide to

discontinue

businesses

or products,

due to

lack

of customer

acceptance

or unprofitability.

Failure to

successfully develop and implement new lines of business or offerings of new products, product enhancements or services

could have an adverse effect on our business, financial condition and results

of operations and could subject us to new and

unanticipated operational, credit, regulatory and reputational risks,

among other risks.

Our business

needs and

future growth

may require

us to

raise additional

capital and

that capital

may not

be

available on terms acceptable to us or may be dilutive to

existing shareholders.

We believe that we

have sufficient capital

to meet our capital

needs for our current

growth plans. However,

we expect

that we

will need

to raise

additional capital,

in the

form of

debt or

equity securities,

in the

future to

have sufficient

capital

resources

to

meet

our

longer-term

growth

plans,

and/or

if

the

quality

of

our

assets

or

earnings

were

to

deteriorate

significantly.

In addition, we

are required by federal

regulatory authorities to

maintain adequate levels

of capital to support

our operations.

Our ability

to raise

capital will

depend on,

among other

things, conditions

in the

capital markets,

which are

outside of

our control, and our financial performance. Accordingly,

we cannot provide assurance that such capital will

be available on

terms acceptable to us or at all. Any occurrence

that limits our access to capital may adversely

affect our capital costs and

our ability to raise capital. Further, if we need to raise capital in the future, we may have to do so when many other financial

institutions are also

seeking to

raise capital and

would then have

to compete with

those institutions for

investors. Any inability

to raise capital on acceptable terms when needed may cause us to

either issue additional shares of common stock or other

securities on less than

desirable terms or

reduce our rate of

growth until market conditions

become more favorable. If

any

of such

events occur, they could

have a material

adverse effect on

our business, financial

condition and results

of operations

and could be dilutive to both tangible book value and our

share price.

Federal law requires that a holding company act as a source of financial and managerial strength to its subsidiary bank

and to

commit

resources

to support

such subsidiary

bank. Under

the “source

of strength”

doctrine, the

Federal Reserve

may

require

a

holding

company

to

make

capital

injections

into

a

troubled

subsidiary

bank

and

may

charge

the

holding

company with

engaging

in unsafe

and unsound

practices

for failure

to commit

resources

to a

subsidiary

bank. A

capital

injection may be required

at times when the

holding company may

not have the resources

to provide it and

therefore may

be required to attempt to

borrow the funds or raise

capital. Thus, any borrowing that must

be done by the Company

to make

a required

capital injection becomes

more difficult and

expensive and

could have

an adverse

effect on our

business, financial

condition and results of operations.

Moreover, it is possible that we will be

unable to borrow funds or

otherwise raise capital

at a

time when

it is

needed. In

addition, an

inability to

raise capital

when needed

may subject

us to

increased regulatory

supervision and

the

imposition of

restrictions

on our

growth

and business.

These restrictions

could

negatively

affect

our

ability

to

operate

or

further

expand

our

operations

through

loan

growth,

acquisitions

or

the

establishment

of

additional

branches. These restrictions may also

result in increases in operating

expenses and reductions in revenues

that could have

a material adverse effect on our financial condition,

results of operations and our share price.

We may

grow through

mergers or

acquisitions,

a strategy

that may

not be

successful or,

if successful,

may

produce risks in successfully integrating and managing the merged companies or acquisitions and may dilute our

shareholders.

As

part

of

our

growth

strategy,

we

may

pursue

mergers

and

acquisitions

of

banks

and

non-bank

financial

services

companies within or outside our principal market areas that fit within the mission-driven values of our franchise and that we

believe support our business and make financial and strategic

sense. We may have difficulty identifying suitable acquisition

candidates or executing on acquisitions that we pursue, and we may

not realize the anticipated benefits of any transactions

we complete. Additionally,

for any opportunistic

acquisition we were

to consider,

we expect to

face significant

competition

from

numerous

other

financial

services

institutions,

many

of

which

will

have

greater

financial

resources

than

we

do.

Accordingly,

attractive opportunistic

acquisitions

may

not be

available to

us. There

can be

no assurance

that we

will

be

successful in identifying or completing any future acquisitions.

Mergers and acquisitions involve numerous risks, any

of which could harm our business, including:

the possibility that expected benefits

may not materialize in the

time frame expected or at

all, or may be more

costly

to achieve, or that the acquired business will not perform

to our expectations;

time,

expense

and

difficulties

in

integrating

the

operations,

management,

products

and

services,

technologies,

existing contracts, accounting processes

and personnel of the target

and realizing the anticipated synergies

of the

combined businesses;

incurring the

time and

expense associated with

identifying and

evaluating potential acquisitions

and merger

partners

and negotiating potential transactions, resulting in management’s attention being diverted from the operation of our

existing business;

difficulties in supporting and transitioning customers

of the target and disruption of our ongoing banking

business;

the price we

pay or other

resources that we

devote may exceed

the value we

realize, or the

value we could

have

realized if we had allocated the purchase consideration

or other resources to another opportunity;

entering new markets or areas in which we have limited or

no experience;

the possibility that our culture is disrupted as a result of

an acquisition;

potential loss of key personnel and customers from either

our business or the target’s business;

assumption of unanticipated problems, claims or other liabilities

of the acquired business;

an inability to realize expected synergies or returns on

investment;

the possibility of regulatory approval for the acquisition being delayed,

impeded, restrictively conditioned, including

the requirement to divest

various activities, or denied

due to existing or

new regulatory issues surrounding

us, the

target institution or the proposed combined entity and

the possibility that any such issues associated with

the target

institution, of which

we may or

may not be

aware at the

time of the

acquisition, could adversely impact

the combined

entity after completion of the acquisition;

the possibility that the acquisition may not be timely completed,

if at all;

the need to raise capital; and

inability to generate sufficient revenue to offset

acquisition costs.

Any acquisition activities we engage in could require us to use a substantial amount of cash, other liquid assets, and/or

incur debt. Also, if

we finance acquisitions by issuing equity securities,

our existing shareholders’ ownership may be

diluted,

which

could

negatively

affect

the

market

price

of

our

Class

A

common

stock.

Additionally,

if

the

goodwill

recorded

in

connection with our potential future acquisitions were determined to be impaired, then we would be required to recognize a

charge against our earnings, which

could materially and adversely affect our

results of operations during the

period in which

the impairment was recognized. Acquisitions

may also involve the payment

of a premium over book

and market values and,

Table of Contents

therefore, some

dilution of

our tangible

book value

and net

income per

common share

may occur

in connection

with any

future transaction.

As a result, we

may not achieve the

anticipated benefits of

any such merger or

acquisition, and we

may incur costs

in

excess

of

what

we

anticipate.

Our

failure

to

successfully

evaluate

and

execute

mergers,

acquisitions

or

investments

or

otherwise adequately address and manage

the risks associated with

such transactions could have

a material adverse effect

on our business, results of operations and financial condition,

including short-term and long-term liquidity.

The loss of

one or more

of our key

personnel, or our

failure to attract

and retain other

highly qualified personnel

in the future, could harm our business.

Our future success will, to some extent, depend on the continued service of our directors, executive officers and senior

management

team.

The

loss

of

the

services

of

any

of

these

individuals

could

have

a

significant

adverse

effect

on

our

business.

In

particular,

we

believe

that

retaining

Luis

de

la

Aguilera,

our

President

and

Chief

Executive

Officer,

Robert

Anderson, our Chief Financial

Officer,

and William Turner,

our Chief Credit Officer,

is important to our continuing

success.

Although

we

have

entered

into

employment

and

other

agreements

with

certain

members

of

our

executive

and

senior

management team,

including Mr.

de la

Aguilera and

Mr.

Anderson, no

assurance can

be given

that these

individuals will

continue to be employed by us. The loss of any of these individuals could negatively affect our ability to achieve our growth

strategy and could have a material adverse effect

on our business and results of operations.

We also need to continue

to attract and retain other senior

management and to recruit qualified

individuals to succeed

existing

key

personnel

to

ensure

the continued

growth

and successful

operation

of our

business.

We

may

be unable

to

attract or

retain qualified

management

and other

key

personnel

in the

future due

to the

intense competition

for qualified

personnel

among

companies

in

the

financial

services

business

and

related

businesses.

The

loss

of

the

services

of any

senior management personnel, or the inability to recruit

and retain qualified personnel in the future, could

have an adverse

effect on our business, results of

operations, financial condition and prospects.

Additionally,

to attract and retain personnel

with appropriate skills and

knowledge to support our

business, we may offer

a variety of benefits, including

equity awards,

which may reduce our earnings or adversely affect our

business, results of operations, financial condition or prospects.

Damage to our reputation could significantly harm

our businesses.

Our ability to attract

and retain customers and

highly-skilled management and employees is impacted

by our reputation.

A negative public

opinion of us

and our business

can result from

any number of

activities, including our

lending practices,

corporate

governance

and

regulatory

compliance,

acquisitions,

customer

complaints

and

actions

taken

by

community

organizations in

response to

these activities.

Furthermore, negative

publicity regarding

us as

an employer

could have

an

adverse

impact on

our reputation,

especially

with respect

to

matters of

diversity,

pay equity

and workplace

harassment.

Significant

harm

to

our

reputation

could

also

arise

as

a

result

of

regulatory

or

governmental

actions,

litigation

and

the

activities of our customers, other

participants in the financial services

industry or our contractual counterparties, such

as our

service providers

and vendors.

The potential

harm

is heightened

given

increased attention

to how

corporations

address

environmental, social

and governance

issues. In

addition, a cybersecurity

event affecting

us or our

customers' data

could

have a negative

impact on our

reputation and

customer confidence

in us and

our cybersecurity

practices. Damage

to our

reputation could also

adversely affect

our credit ratings

and access to

the capital markets.

Additionally,

whereas negative

public opinion once was

primarily driven by adverse

news coverage in traditional

media, the widespread use

of social media

platforms by

virtually every

segment of

society facilitates

the rapid

dissemination

of information

or misinformation,

which

magnifies the potential harm to our reputation.

We

face

strong

competition

from

financial

services

companies

and

other

companies

that

offer

banking

services, which could materially and adversely affect

our business.

The financial

services industry has

become even

more competitive as

a result

of legislative,

regulatory and technological

changes and

continued

banking consolidation,

which

may increase

as a

result of

current economic,

market and

political

conditions. We

face substantial

competition

in all

phases

of our

operations

from

a variety

of competitors,

including local

banks,

regional

banks,

community

banks

and,

more

recently,

financial

technology,

or

"fintech"

companies.

Many

of

our

competitors offer the same banking services that

we offer and our success depends on

our ability to adapt our

products and

services

to

evolving

industry

standards

and

customer

requirements.

Increased

competition

in

our

market

may

result

in

reduced new

loan and

lease production

and/or decreased

deposit balances

or less

favorable terms

on loans

and leases

and/or deposit

accounts. We also

face competition

from many

other types

of financial

institutions, including

without limitation,

non-bank

specialty

lenders,

insurance

companies,

private

investment

funds,

investment

banks,

and

other

financial

intermediaries. Should competition in

the financial services industry

intensify, our ability to market our

products and services

may be adversely affected. If we are unable to attract and retain banking customers, we may be

unable to grow or maintain

Table of Contents

35

USCB Financial Holdings, Inc.

the levels

of our

loans and

deposits and

our results

of operations

and financial

condition may

be adversely

affected as

a

result. Ultimately, we

may not be able to compete successfully against current

and future competitors.

We must respond to rapid technological changes

to remain competitive.

We will

have to respond

to future

technological changes,

which are occurring

at a rapid

pace in the

financial services

industry.

We

expect

that

new

technologies

and

business

processes

applicable

to

the

banking

industry

will

continue

to

emerge, and these

new technologies and business

processes may be

better than those

we currently use. Because

the pace

of technological change

is high and our

industry is intensely

competitive, our future

success will depend,

in part, upon our

ability to address

the needs of

our customers by using

technology to provide products

and services that

will satisfy customer

demands for convenience,

as well as to

create additional efficiencies

in our operations.

We may not

be able to implement

new technology-driven products

and services effectively

or be successful

in marketing these

products and services

to our

customers. Failure to keep pace successfully with technological change affecting the financial services industry could harm

our

ability

to

compete

effectively

and

could

have

an

adverse

effect

on

our

business,

financial

condition

and

results

of

operations. As

these

technologies

improve

in the

future,

we may

be required

to make

significant

capital

expenditures

in

order to remain

competitive, which may increase

our overall expenses

and have an

adverse effect on our

business, financial

condition and results of operations.

We

continually

encounter

technological

change,

and

we

may

have

fewer

resources

than

many

of

our

competitors to invest in technological improvements.

The financial

services industry is

undergoing rapid technological

changes with frequent

introductions of new

technology-

driven products and

services. The effective use

of technology increases efficiency

and enables financial institutions

to better

serve customers and to reduce

costs. Our future success

will depend, in part, upon

our ability to address the

needs of our

clients by using technology to

provide products and services

that will satisfy client demands

for convenience, as well

as to

create additional

efficiencies in our operations. Many national vendors provide turn-key services to community banks, such

as internet banking and remote deposit capture that allow smaller banks to compete

with institutions that have substantially

greater resources

to invest

in technological

improvements.

We

may

not

be

able,

however,

to effectively

implement

new

technology-driven products and services or be successful

in marketing these products and services to our customers.

A

failure,

interruption,

or

breach

in

the

security

of

our

systems,

or

those

of

our

contracted

vendors,

could

disrupt

our

business,

result

in

the

disclosure

of

confidential

information,

damage

our

reputation,

and

create

significant financial and legal exposure.

Although we

devote significant

resources to maintain

and regularly update

our systems and

processes that are

designed

to

protect

the

security

of

our

computer

systems,

software,

networks

and

other

technology

assets,

as

well

as

the

confidentiality,

integrity and availability

of information belonging

to us and

our customers,

there is no

assurance that

all of

our

security

measures

will

provide

absolute

security.

Many

financial

institutions,

including

us,

have

been

subjected

to

attempts to infiltrate the security of their websites or other systems, some involving sophisticated targeted

attacks intended

to obtain

unauthorized access

to confidential

information, destroy

data, disrupt

or degrade

service, sabotage

systems or

cause other damage, including through the introduction of

computer viruses or malware, cyber-attacks and other means. At

this point,

although there

is no

knowledge or

indication that we

have experienced a

material cyber-incident or

security breach

that has been successful in compromising our

data or systems to date, we can

never be certain that all of our

systems are

entirely free from vulnerability to breaches of security or

other technological difficulties or failures.

Despite efforts to

ensure the integrity

and security of

our systems, it

is possible that

we may not

be able to

anticipate,

detect or recognize

threats to our

systems or to

implement effective

preventive measures

against all efforts

to breach our

security inside or outside our business, especially because the techniques used to attack our systems

change frequently or

are

not

recognized

until

launched,

and

because

cyber-attacks

can

originate

from

a

wide

variety

of

sources,

including

individuals or groups who are associated with

external service providers or who are or

may be involved in organized crime

or linked

to terrorist

organizations or

hostile foreign

governments. Those

parties may

also attempt

to fraudulently

induce

employees, customers, third-party service providers or other users of our systems to disclose sensitive information in order

to gain access

to our data or

that of our customers

or clients. Similar

to other companies,

our risks and exposures

related

to cybersecurity attacks have increased as

a result of the related increased

reliance on remote working (largely

as a result

of the COVID-19 pandemic)

and the increase in

digital operations. Such

risks and exposures

are expected to

remain high

for the foreseeable

future due

to the rapidly

evolving nature

and sophistication

of these

threats and

the expanding

use of

technology, as our web

-based product offerings grow and we expand

internal usage of web-based applications.

A successful

penetration

or

circumvention

of the

security

of our

systems,

including those

of our

third-party

vendors,

could

cause

serious

negative

consequences,

including

significant

disruption

of

our

operations,

misappropriation

of

confidential information,

or damage

to computers

or systems,

and may

result in violations

of applicable

privacy and

other

laws, financial loss,

loss of confidence

in our security measures,

customer dissatisfaction, increased

insurance premiums,

significant litigation exposure and harm to our reputation, all of which could have a material adverse effect on our business,

financial condition, results of operations, and future prospects.

We

rely

on

other

companies

to

provide

key

components

of

our

business

infrastructure

and

our

operations

could

be

interrupted

if

our

third-party

service

providers

experience

difficulty,

terminate

their

services

or

fail

to

comply with banking regulations.

Third parties

provide key

components of

our business

operations such

as data

processing, recording

and monitoring

transactions,

online

banking

interfaces

and services,

Internet

connections

and

network

access.

While

we

have

selected

these third-party

vendors carefully,

performing upfront

due diligence

and ongoing

monitoring activities,

we do

not control

their actions. Any problems caused by these third parties, including those resulting from disruptions in services provided by

a

vendor

(including

as

a

result

of

a

cyber-attack,

other

information

security

event

or

a

natural

disaster),

financial

or

operational difficulties

for the vendor,

issues at third-party

vendors to our

vendors, failure of

a vendor to

handle current or

higher volumes, failure of a vendor to provide services for

any reason, poor performance of services, failure to comply

with

applicable laws

and regulations,

or fraud

or misconduct

on the

part of

employees of

any of

our vendors,

could adversely

affect our ability

to deliver products

and services to

our customers, our

reputation and our

ability to conduct

our business,

which could

adversely affect

our business,

prospects, cash

flow,

liquidity,

financial condition

and results

of operations.

In

certain

situations,

replacing

these

third-party

vendors

could

also

create

significant

delay,

expense,

and

operational

difficulties, which

could also

adversely affect

our business.

Accordingly,

use of

such third

parties creates

an unavoidable

and inherent

risk to

our business

operations. Such

risk is

generally expected

to remain

elevated as

many of

our vendors

have also

been, and

may

further be,

affected

by increased

reliance

on remote

work

environments,

market

volatility

and

other factors

that increase

their risks

of business

disruption or

that may

otherwise affect

their ability

to perform

under the

terms of any agreements with us or provide essential services.

Our operations could be interrupted or

materially impacted if any of our

third-party service providers fail to comply

with

banking regulations

and other

applicable laws.

The Federal

Reserve, FDIC,

FOFR, and

other regulators

expect financial

institutions

to

be

responsible

for

all

aspects

of

their

performance,

including

aspects

that

they

delegate

to

third

parties.

Accordingly,

we will

be responsible

for deficiencies

in our

oversight and

control of

our third

party relationships

and in

the

performance of the parties with which

we have these relationships. As

a result, if our regulators conclude that

we have not

exercised adequate oversight and control over our third party vendors or

other ongoing third party business relationships or

that

such

third

parties

have

not

performed

appropriately,

we

could

be

subject

to

remedial

and/or

enforcement

actions,

including civil

money penalties

or other

administrative

or judicial

penalties or

fines

as well

as requirements

for customer

remediation, any of which could have a material adverse

effect our business, financial condition or results

of operations.

Litigation and regulatory actions,

including possible enforcement actions, could subject

us to significant fines,

penalties,

judgments

or

other

requirements

resulting

in

increased

expenses

or

restrictions

on

our

business

activities.

In the normal course of

business, from time to time, we

have in the past and

may in the future be

named as a defendant

in various

legal actions

arising in

connection with

our current

and/or prior

business

activities. Legal

actions could

include

claims for substantial compensatory and/or

punitive damages or claims for indeterminate

amounts of damages. Further,

in

the future

our

federal

and/or

state

bank

regulators

may

impose

consent

orders,

civil

money

penalties,

matters

requiring

attention, or similar types of

supervisory penalties or criticism. We may also,

from time to time, be

the subject of subpoenas,

requests

for

information,

reviews,

investigations

and

proceedings

(both

formal

and

informal)

by

governmental

agencies

regarding our

current

and/or prior

business

activities.

Any such

legal or

regulatory

actions may

subject

us to

substantial

compensatory

or

punitive

damages,

significant

fines,

penalties,

obligations

to

change

our

business

practices

or

other

requirements resulting

in increased

expenses, diminished

income and

damage to

our reputation.

Our involvement

in any

such matters,

whether tangential

or otherwise

and

even if

the matters

are ultimately

determined

in our

favor,

could also

cause significant harm to our

reputation and divert management attention away from

the operation of our business.

Further,

any settlement, consent order or adverse judgment in connection with any formal or informal proceeding or investigation by

government

agencies

may

result

in

litigation,

investigations

or

proceedings

as

other

litigants

and

government

agencies

begin independent

reviews of

the same

activities. As

a result,

the outcome

of legal

and regulatory

actions could

have an

adverse effect on our business, results of operations

and results of operations.

Certain of

our directors may

have conflicts

of interest in

determining whether to

present business

opportunities

to us or another entity with which they are, or may

become, affiliated.

Certain of our

directors are or may

become subject to fiduciary

obligations in connection with

their service on the

boards

of

directors

of

other

corporations,

including

financial

institutions.

A

director's

association

with

other

financial

institutions,

which give rise to

fiduciary or contractual obligations to such other

institutions, may create conflicts of interest. To the extent

Table of Contents

37

USCB Financial Holdings, Inc.

2023 10-K

that any of our directors

become aware of acquisition

opportunities that may be

suitable for entities other

than us to which

they have fiduciary or contractual obligations, or they are

presented with such opportunities in their capacities as fiduciaries

to such

entities, they

may honor

such obligations

to such

other entities.

You

should assume

that to

the extent

any of

our

directors become aware

of an opportunity

that may be

suitable both for

us and another

entity to which

such person has

a

fiduciary obligation

or contractual

obligation

to present

such

opportunity as

set forth

above,

he or

she may

first give

the

opportunity to such other entity

or entities and may give

such opportunity to us only

to the extent such other

entity or entities

reject

or

are

unable

to

pursue

such

opportunity.

In

addition,

you

should

assume

that

to

the

extent

any

of

our

directors

become

aware

of

an

acquisition

opportunity

that

does

not

fall

within

the

above

parameters,

but

that

may

otherwise

be

suitable for us, he or she may not present such opportunity

to us.

Pursuant to an agreement between us and each of our Significant Investors

(as defined below), each of the Significant

Investors has the right

to nominate one

director to serve

on our Board, including

Board committees, and

to designate one

non-voting Board

observer.

The directors

and Board

observers

designated by

the Significant

Investors have

the right

to,

and have

no duty

not to,

engage in

the same

or similar

business activities

or lines

of business

as us.

In the

event that

a

director or Board observer designated by a Significant Investor acquires knowledge of a potential transaction or matter that

may be

a corporate opportunity

for us,

such person shall

have no

duty to

communicate or

present such corporate

opportunity

to us

and shall

not be

liable to

us or

our shareholders

for breach

of any

duty by

reason of

the fact

that such

person or

a

related investment fund

thereof, directly or

indirectly, pursues or acquires such opportunity

for itself, directs

such opportunity

to another person, or does not present such opportunity

to us.

Risks Related to Our Tax,

Accounting and Regulatory Compliance

Our ability to recognize

the benefits of

our deferred tax

assets is dependent

on future cash flows

and taxable

income and may be materially impaired upon significant

changes in ownership of our common stock.

We recognize the expected future tax

benefit from deferred tax assets when

it is more likely than

not that the tax benefit

will be

realized. Otherwise,

a valuation

allowance

is applied

against our

deferred

tax assets,

reducing

the value

of such

assets. Assessing

the recoverability

of deferred

tax assets

requires management

to make significant

estimates related

to

expectations

of

future

taxable

income

from

all

sources,

including

reversal

of

taxable

temporary

differences,

forecasted

operating

earnings

and

available

tax

planning

strategies.

Estimates

of

future

taxable

income

are

based

on

forecasted

income from operations and the application of existing tax laws in each jurisdiction. The improved risk profile of the Bank is

a key

component used

in the determination

of our

ability to

realize the

expected future

benefit of

our deferred

tax assets.

To

the extent that future taxable income differs

significantly from estimates as a result

of the interest rate environment and

loan growth capabilities or other factors, our ability to realize

the net deferred tax assets could be negatively

affected.

Subject to certain exceptions, our Class A common stock is subject

to transfer restrictions as set forth in our Articles of

Incorporation that are

designed to preserve

our deferred tax

assets. Notwithstanding these

protective provisions, the

Articles

of Incorporation include

an exception that

allows our Significant

Investors the right

to effect any

transfer that would

otherwise

be prohibited, which transfer could result in the loss of the deferred

tax assets.

Additionally,

significant future

issuances of

common stock

or common

stock equivalents,

or changes

in the

direct or

indirect ownership

of our

common stock

or common

stock equivalents,

could cause

an ownership

change and

could limit

our ability to

utilize our net

operating loss carryforwards

and other tax

attributes pursuant

to Section 382

and Section 383

of the Internal Revenue Code.

Future changes in tax law or

changes in ownership structure could

limit our ability to utilize

our recorded net deferred tax assets.

The

accuracy

of

our

financial

statements

and

related

disclosures

could

be

affected

if

the

judgments,

assumptions or estimates used in our critical accounting

policies are inaccurate.

The

preparation

of

our

financial

statements

and

related

disclosures

in

conformity

with

GAAP

requires

us

to

make

judgments,

assumptions

and

estimates

that

affect

the

amounts

reported

in

our

consolidated

financial

statements

and

accompanying notes. In some cases, management

must select the accounting policy or method

to apply from two or more

alternatives,

any of

which

may be

reasonable

under

the circumstances,

yet

which

may result

in

our

reporting

materially

different

results

than

would

have

been

reported

under

a

different

alternative.

Certain

accounting

policies

are

critical

or

significant to presenting our financial

condition and results of

operations. Our critical accounting policies, which

are included

in the section captioned "Management's Discussion and Analysis of Financial Condition and Results

of Operations" in Item

7 of this Annual Report

on Form 10-K, describe

those significant accounting

policies and methods used

in the preparation

of

our

consolidated

financial

statements

that

we

consider

critical

because

they

require

judgments,

assumptions

and

estimates that materially affect our consolidated financial statements and related disclosures. As a result, if

future events or

regulatory views concerning such analyses differ significantly from the judgments, assumptions and estimates in

our critical

accounting policies,

those events

or assumptions

could have

a material

impact on

our consolidated

financial statements

Table of Contents

38

USCB Financial Holdings, Inc.

2023 10-K

and

related

disclosures,

in

each

case

resulting

in

our

need

to

revise

or

restate

prior

period

financial

statements,

cause

damage to our

reputation and

the price

of our Class

A common stock

and adversely affect

our business, prospects,

cash

flow, liquidity,

financial condition and results of operations.

As a new public

company, we may not efficiently or effectively create an

effective internal control environment,

and any

future failure

to maintain

effective internal

control over

financial reporting

could impair

the reliability

of

our financial

statements, which

in turn could

harm our business,

impair investor

confidence in the

accuracy and

completeness of

our financial

reports and

our access

to the

capital markets,

cause the

price of

our Class

A common

stock to decline and subject us to regulatory penalti

es.

Our management is responsible for establishing

and maintaining adequate internal control over financial

reporting and

for evaluating

and

reporting

on

that

system

of

internal

control.

Our

internal

control

over

financial

reporting

consists

of

a

process

designed

to

provide

reasonable

assurance

regarding

the

reliability

of

financial

reporting

and

the

preparation

of

financial statements for external purposes in accordance with GAAP.

As a public company,

we are required to comply with

SEC regulations, including

the Sarbanes-Oxley Act

and other rules

that govern public

companies that we

previously were

not required to comply with

as a private company.

In particular,

we are required to certify

our compliance with Section

404

of the

Sarbanes-Oxley Act, which

requires us to

annually furnish

a report by

management on the

effectiveness of our

internal

control

over

financial

reporting.

When

evaluating

our

internal

controls

over

financial

reporting,

we

may

identify

material

weaknesses that we may not be able to remediate in time to meet the applicable deadline imposed upon us for compliance

with the requirements of Section 404 of the Sarbanes-Oxley Act. We periodically review our formal policies, processes and

practices related to financial reporting

and to the identification of

key financial reporting risks, assess

their potential impact

and the linkage of those risks to specific areas and controls

within our organization.

If we fail to achieve and maintain the adequacy of

our internal controls, as such standards are modified, supplemented,

or amended from time to

time, we may not

be able to ensure

that we will be able

to conclude on an ongoing

basis that we

have

effective

internal

controls

over

financial

reporting

in

accordance

with

Section

404

of

the

Sarbanes-Oxley

Act.

We

cannot be certain as to the timing of completion of our evaluation, testing,

and any remediation actions or the impact of the

same on our

operations. If

we fail to

adequately comply

with the requirements

of Section

404 of the

Sarbanes-Oxley Act,

we may be subject to adverse regulatory consequences and

there could be a negative reaction in the

financial markets due

to a loss of investor confidence in us and the

reliability of our financial statements. In addition,

we may be required to incur

costs in improving

our internal control

system and

hiring additional

personnel. Any

such action could

negatively affect

our

business, financial condition, results of operations, and the

price of our Class A common stock may decline.

While we remain an

emerging growth company or a

non-accelerated smaller reporting company, we will not be

required

to

include

an

attestation

report

on

internal

control

over

financial

reporting

issued

by

our

independent

registered

public

accounting firm.

To

prepare for

eventual compliance

with the auditor

attestation requirement

of Section

404 of

Sarbanes-

Oxley once we no

longer qualify as an

emerging growth company

or as a non-accelerated

smaller reporting company,

we

are engaged

in a process

to document

and evaluate

our internal

control over

financial reporting,

which is

both costly

and

challenging. In this regard, we will need to

dedicate internal resources, potentially engage

outside consultants and adopt a

detailed

work

plan

to

assess

and

document

the

adequacy

of

internal

control

over

financial

reporting,

continue

steps

to

improve control

processes as appropriate,

validate through testing

that controls are

functioning as documented

and continue

to refine our

reporting and improvement

process for

internal control over

financial reporting. Despite

our efforts,

there is a

risk that

we will

not be

able to

conclude, within

the prescribed

time frame

or at

all, that

our internal

control over

financial

reporting is effective as

required by Section 404

of Sarbanes-Oxley. If we identify one

or more material weaknesses,

it could

result in an adverse reaction in the financial markets due to a

loss of confidence in the reliability of our financial statements.

We

operate

in

a

highly

regulated

environment,

and

the

laws

and

regulations

that

govern

our

operations,

corporate governance,

executive compensation

and accounting

principles, or

changes in

them, or

our failure

to

comply with them, could adversely affect us.

We operate in a

highly regulated industry and

we are subject to

examination, supervision and comprehensive

regulation

by various federal and state agencies,

including the Federal Reserve, the

FDIC and the FOFR. As

such, we are subject to

extensive regulation, supervision and

legal requirements that govern almost

all aspects of our operations.

These laws and

regulations

are

not

intended

to

protect

our

shareholders.

Rather,

these

laws

and

regulations

are

intended

to

protect

customers, depositors, the Deposit Insurance Fund,

or DIF, and the overall financial health and

stability of the United

States

banking

system.

These

laws

and

regulations,

among

other

matters,

prescribe

minimum

capital

requirements,

impose

limitations on the

business activities

and investments

in which we

can engage, regulate

and restrict our

lending activities,

require us to provide certain banking services broadly within the communities in which we operate,

determine the locations

of our branch

offices and impose certain

specific accounting requirements on us

that may be more

restrictive and may result

in

greater

or

earlier

charges

to

earnings

or

reductions

in

our

capital

than

GAAP

would

require.

We

are

also

subject

to

capitalization

guidelines

established

by

our

regulators,

which

require

us

to

maintain

adequate

capital

to

support

our

Table of Contents

business.

Compliance

with

laws

and

regulations

can

be

difficult

and

costly,

and

changes

to

laws

and

regulations

often

impose additional operating costs. Further, we must obtain approval from our

regulators before engaging in many activities,

and

our

regulators

have

the

ability

to

compel

us

to,

or

restrict

us

from,

taking

certain

actions

entirely.

There

can

be

no

assurance that any regulatory approvals we may require

or otherwise seek will be obtained.

Regulations affecting

banks and

other financial

institutions are

undergoing continuous

review and

frequently change,

and the ultimate effect of such changes cannot be predicted. Changes to the legal and regulatory framework governing our

operations, including

the Dodd-Frank

Wall

Street Reform

and Consumer

Protection Act,

or the

Dodd-Frank

Act, and

the

Economic Growth, Regulatory Relief and Consumer

Protection Act, or the Regulatory Relief

Act, have significantly revised

the laws and regulations under which we operate. Such regulations and laws may be modified or repealed at any time, and

new legislation may be enacted that will affect us and

our subsidiaries.

Our failure to comply with these laws and regulations, even if the failure follows good faith effort

or reflects a difference

in

interpretation,

could

subject

us

to

restrictions

on

our

business

activities,

enforcement

actions

and

fines

and

other

penalties,

any

of

which

could

adversely

affect

our

results

of

operations,

regulatory

capital

levels

and

the

price

of

our

securities. Further, any new laws, rules and

regulations, such as were imposed

under the Dodd-Frank Act or

the Regulatory

Relief Act, could make

compliance more difficult

or expensive or otherwise

adversely affect our

business, prospects, cash

flow, liquidity,

financial condition and results of operations.

We

face

a

risk

of

noncompliance

with

the

Bank

Secrecy

Act

and

other

anti-money

laundering

statutes

and

regulations and corresponding enforcement proceedings.

The

federal

Bank

Secrecy

Act,

the

Uniting

and

Strengthening

America

by

Providing

Appropriate

Tools

Required

to

Intercept and

Obstruct Terrorism

Act of

2001, or

the USA

PATRIOT

Act, and

other laws

and regulations

require financial

institutions, among

other duties,

to institute

and maintain

effective anti-money

laundering programs

and to

file suspicious

activity and

currency transaction

reports, as

appropriate. The

federal Financial

Crimes Enforcement

Network, or

FinCEN,

established by the

U.S. Treasury

Department to

administer the

Bank Secrecy

Act, is authorized

to impose significant

civil

money penalties for

violations of those

requirements and has engaged

in coordinated enforcement efforts

with the individual

federal

banking

regulators,

as

well

as

the

U.S.

Department

of

Justice,

Drug

Enforcement

Administration

and

Internal

Revenue Service. Additionally,

South Florida has been designated as a “High Intensity Financial Crime Area” (“HIFCA”)

by

FinCEN and

a “High

Intensity Drug

Trafficking

Area” (“HIDTA”)

by the

Office of

National Drug

Control Policy.

The HIFCA

program is intended to concentrate law enforcement efforts

to combat money laundering efforts in higher-risk

areas. There

is also increased scrutiny of compliance with

the rules enforced by OFAC. Federal and state bank regulators have for many

years

focused

on

compliance

with

Bank

Secrecy

Act

and

anti-money

laundering

regulations.

In

order

to

comply

with

regulations, guidelines and examination procedures in this area, we have

dedicated significant resources

to our anti-money

laundering program, especially

due to the regulatory

focus on financial

and other institutions

located in South

Florida. Our

business

includes

supporting

our

customers,

including

foreign

financial

institutions,

with

respect

to

their

international

banking

needs

and

our policies,

procedures

and

systems

have

been

designed

to

address

federal

and

state

anti-money

laundering

compliance.

If

our

policies,

procedures

and

systems

are

deemed

deficient

or

the

policies,

procedures

and

systems of the

financial institutions that

we may acquire

are deficient, we

would be subject

to liability,

including fines, and

regulatory actions that are

deemed necessary in order

to remediate such deficiencies

and prevent the recurrence

thereof.

In recent years, sanctions that the regulators have

imposed on banks that have not complied with

all anti-money laundering

requirements

have

been

especially

severe.

Failure

to

maintain

and

implement

adequate

programs

to

combat

money

laundering and

terrorist financing

could also

have serious

reputational consequences

for us,

which could

have a

material

adverse effect on our business, financial condition

and results of operations.

We

are

subject

to

capital

adequacy

requirements

and

may

become

subject

to

more

stringent

capital

requirements, which could adversely affect our

financial condition and operations.

In

2013,

the

federal

banking

agencies

published

new

regulatory

capital

rules

based

on

the

international

standards,

known as

Basel III,

that were

developed by

the Basel

Committee on

Banking Supervision.

The new

rules raised

the risk-

based capital

requirements

and revised

the

methods for

calculating

risk-weighted

assets, usually

resulting

in higher

risk

weights. The new rules now apply to us.

The Basel III rules increased

capital requirements and included

two new capital measurements,

a risk-based common

equity Tier 1 ratio

and a capital conservation buffer.

Common Equity Tier

1 (CET1) capital is a subset

of Tier 1 capital

and

is limited to common

equity (plus related surplus), retained earnings,

accumulated other comprehensive income and certain

other

items.

Other

instruments

that

have

historically

qualified

for

Tier

1

treatment,

including

noncumulative

perpetual

preferred stock,

are consigned

to a

category known

as Additional

Tier

1 capital

and must

be phased

out of

CETI over

a

period of

nine years

beginning in

  1. In

order to

be a

“well-capitalized” depository

institution under

the new

regime, an

institution must maintain a

CET1 capital ratio of 7.0%

or more; a Tier

1 capital ratio of 8.5%

or more; a total capital

ratio of

Table of Contents

40

USCB Financial Holdings, Inc.

2023 10-K

10.5% or more; and a leverage ratio of 4% or more.

Institutions must also maintain a capital conservation

buffer consisting

of common equity

Tier 1

capital. In addition

to the higher

required capital ratios

and the new

deductions and adjustments,

the final

rules increased

the risk

weights for

certain assets,

meaning that

we will

have to

hold more

capital against

these

assets. We are also be required to hold capital against

short-term commitments that are not unconditionally cancellable.

While we currently meet these new

requirements of the Basel III-based capital requirements, we

may fail to do so

in the

future. The failure

to meet applicable

regulatory capital

requirements could result

in one or

more of our

regulators placing

limitations or conditions on our activities, including our growth initiatives, or restricting the commencement of new activities,

and could affect customer and investor confidence, our costs of funds and level of required deposit insurance

assessments

to the FDIC,

our ability to

pay dividends on

our capital stock,

our ability to

make acquisitions, and

our business, results

of

operations and financial condition, generally.

In addition,

in the

current economic

and regulatory

environment, including

the COVID-19

pandemic, bank

regulators

may

impose

capital

requirements

that

are

more

stringent

than

those

required

by

applicable

existing

regulations.

The

application of more stringent capital requirements for

us could, among other things, result

in lower returns on equity, require

the raising of additional

capital, and result

in regulatory actions if

we were to be

unable to comply with

such requirements.

Implementation

of

changes

to

asset

risk

weightings

for

risk-based

capital

calculations,

items

included

or

deducted

in

calculating regulatory capital or additional capital conservation buffers, could result in management modifying our business

strategy and could limit our ability to make distributions,

including paying dividends.

We are periodically subject

to examination and

scrutiny by a

number of banking agencies

and, depending upon

the findings and determinations

of these agencies, we may

be required to make adjustments

to our business that

could adversely affect us.

As part of

the bank regulatory process,

the Federal Reserve, the

FDIC and the FOFR

periodically conduct examinations

of our business,

including compliance

with applicable

laws and regulations.

If, as a

result of an

examination, one

of these

banking

agencies

were

to

determine

that

the

financial

condition,

capital

resources,

asset

quality,

asset

concentration,

earnings prospects, management, liquidity sensitivity

to market risk, risk

management and internal controls

or other aspects

of any of our operations has become unsatisfactory, or that we or our management are in violation of any law or regulation,

the banking

agency could

take a

number of

different remedial

or punitive

actions as

it deems

appropriate. These

actions

include the power to prohibit the continuation

of "unsafe or unsound" practices, to require

affirmative actions to correct any

conditions

resulting

from

any

violation

or practice,

to

issue an

administrative

order

or enforcement

that

can

be judicially

enforced, to direct an increase

in our capital, to restrict our

growth, to change the asset composition

of our loan or securities

portfolios

or

balance

sheet,

to

assess

civil

monetary

penalties

against

our

officers

or

directors,

to

remove

officers

and

directors and, if

it is concluded

that such conditions

cannot be corrected

or there is

an imminent risk

of loss to

depositors,

to

terminate

our

deposit

insurance

and

force

us

to

terminate

our

business

operations.

If

we

become

subject

to

such

regulatory actions, our business, financial condition, result

s

of operations and reputation may be negatively impacted.

We

are

subject

to

numerous

laws

and

regulations

of

certain

regulatory

agencies

designed

to

protect

consumers, including the Community Reinvestment

Act, or CRA, and fair lending laws, and failure

to comply with

these laws could lead to a wide variety of sanctions.

The CRA directs all insured depository institutions to help meet the credit needs of the local communities

in which they

operate

branches,

including

low-

and

moderate-income

neighborhoods.

Each

institution

is

examined

periodically

by

its

primary federal

regulator,

which assesses

the institution’s

CRA performance.

The Equal

Credit Opportunity

Act, the

Fair

Housing

Act

and

other

fair

lending

laws

and

regulations

impose

nondiscriminatory

lending

requirements

on

financial

institutions. The U.S. Department of Justice, the Federal Reserve, and other federal agencies are responsible for enforcing

these laws and regulations. A successful regulatory challenge to our performance under the CRA, fair lending or consumer

lending

laws

and

regulations

could

result

in

a

wide

variety

of

sanctions,

including

damages

and

civil

money

penalties,

injunctive

relief,

customer

restitution,

restrictions

on

mergers

and

acquisitions

activity,

restrictions

on

expansion,

and

restrictions

on

entering

new

business

lines.

Private

parties

may

also

have

the

ability

to

challenge

an

institution’s

performance

under

fair

lending

laws

in

private

class

action

litigation.

Such

actions

could

have

an

adverse

effect

on

our

business, financial condition and results of operations.

Climate change and related legislative and regulatory initiatives may materially affect our business and results

of operations.

The effects

of climate change

continue to create

a significant level

of concern

for the state

of the global

environment.

As a result, the global business community has increased

its political and social awareness surrounding the issue,

and the

United States

has entered

into international

agreements in

an attempt

to reduce

global temperatures,

such as

reentering

the Paris Agreement.

Further,

the U.S. Congress,

state legislatures and

federal and state

regulatory agencies

continue to

propose numerous

initiatives to

supplement the

global effort

to combat

climate change,

including provisions

contained in

the

Inflation

Reduction

Act

of

2022.

Similar

and

even

more

expansive

initiatives

are

expected

under

the

current

administration, including potentially increasing supervisory

expectations with respect to banks’ risk management practices,

accounting for

the effects of

climate change in

stress testing

scenarios and systemic

risk assessments, revising

expectations

for credit portfolio concentrations based on climate-related factors

and encouraging investment by banks in climate-related

initiatives and

lending to

communities disproportionately

impacted by

the effects

of climate

change. The

lack of

empirical

data surrounding the

credit and other

financial risks posed

by climate change

render it difficult, or

even impossible, to

predict

how climate change

may impact our

financial condition

and results of

operations; however,

the physical

effects of

climate

change may also directly impact us. Specifically, unpredictable and more frequent weather disasters may adversely impact

the real property, and/or the

value of the

real property, securing the loans

in our portfolios.

Additionally, if insurance obtained

by

our

borrowers

is

insufficient

to

cover

any

losses

sustained

to

the

collateral,

or

if

insurance

coverage

is

otherwise

unavailable

to

our

borrowers,

the

collateral

securing

our

loans

may

be

negatively

impacted

by

climate

change,

natural

disasters and

related events,

which could

impact our

financial condition

and results

of operations.

Further,

the effects

of

climate change may negatively impact

regional and local economic activity, which could adversely affect our

customers and

the communities in which

we operate. Overall,

climate change, its

effects and the

resulting, unknown impact

could have a

material adverse effect on our financial condition

and results of operations.

Risks Related to Our Class A Common Stock

Our ability to pay dividends is subject to restrictions.

Holders of our Class A common stock

are only entitled to receive cash dividends when, as

and if declared by our Board

out of funds

legally available

for dividends.

The Company

is a bank

holding company

that conducts

substantially all

of its

operations through the Bank,

which is a legal entity

separate and distinct from

the Company.

As a result, our ability

to pay

dividends

on

our

common

stock

will substantially

depend

upon

the

receipt

of

dividends

and

other

distributions

from

the

Bank,

the

profitability

of

which

is

subject

to

the

fluctuating

cost

and

availability

of

money,

changes

in

interest

rates

and

economic conditions in general. There

are numerous laws and banking

regulations and guidance that limit

the Bank's ability

to pay dividends to us and our ability to pay dividends on our

common stock.

The market price and trading volume of our Class A

common stock may be volatile, which could result in rapid

and substantial losses for our shareholders.

The market

price

of

our

Class

A common

stock

may

be highly

volatile

and

could

be

subject

to

wide

fluctuations.

In

addition, the trading volume on

our Class A common stock may

fluctuate and cause significant price variations to

occur. We

cannot assure you that the market price of our Class A common stock will not fluctuate or decline significantly in the future.

Some, but

certainly not

all, of

the factors

that could

negatively affect

the price

of our

Class A

common stock,

or result

in

fluctuations in the price or trading volume of our Class

A common stock, include but not limited to:

general market conditions;

domestic and international economic factors unrelated

to our performance;

variations in our quarterly operating results or failure to

meet the market’s earnings expectations;

publication of research reports about us or the financial services

industry in general;

the determination of securities analysts to not cover our

Class A common stock;

the opinion of securities analysts about our stock as an investment;

additions to or departures of our key personnel;

future sales of our Class A common stock;

adverse market reactions to any indebtedness we may

incur or securities we may issue in the future;

actions by our shareholders;

the operating and securities price performance of companies

that investors consider to be comparable to us;

changes or proposed changes in laws or regulations affecting

our business; and

actual or potential litigation and governmental investigations.

In

addition,

if

the

market

for

stocks

in

our

industry,

or

the

stock

market

in

general,

experiences

a

loss

of

investor

confidence, the

trading price

of the

Class A

common stock

could decline

for reasons

unrelated to

our business,

financial

condition or results of operations.

If any of the foregoing occurs,

it could cause our Class A common

stock price to fall and

may expose us to lawsuits that, even if unsuccessful, could

be costly to defend and a distraction to management.

There are significant restrictions in our Articles of Incorporation that restrict the

ability to sell our capital stock

to shareholders that would own 4.95% or more of our stock,

excluding our Significant Investors.

Because the

continued availability

of our

"deferred tax

assets" depends,

in part,

on the

value of

our stock

owned by

shareholders owning

5% or more

of our stock,

our Articles of

Incorporation, except

as otherwise may

be approved by

the

Board

or

except

for

transfers

by

our

Significant

Investors,

prohibits

any

direct

or

indirect

transfer

of

stock

or

options

to

acquire stock to any

person who, as a

result of the transfer, would own 4.95%

or more of our

stock, as long as the

Company

continues to have "deferred tax assets." Such restrictions may

limit the ability to transfer our stock.

Because

we

are

an

emerging

growth

company

and

because

we

have

decided

to

take

advantage

of

certain

exemptions from

various reporting

and other

requirements applicable

to emerging

growth companies,

our Class

A common stock could be less attractive to investors.

We are

an “emerging

growth company,”

as defined

in the

JOBS Act.

For as

long as

we remain

an emerging

growth

company,

we will

have the

option to take

advantage of

certain exemptions

from various

reporting and

other requirements

that are applicable to other public companies that are not

emerging growth companies, including:

we

may

present

only

two

years

of

audited

financial

statements

and

only

two

years

of

related

management’s

discussion and analysis of financial condition and results

of operations

we

are

exempt

from

the

requirements

to

obtain

an

attestation

and

report

from

our

auditors

on

management’s

assessment of our internal control over financial reporting

under the Sarbanes-Oxley Act;

we are permitted to have less extensive disclosure about our

executive compensation arrangements; and

we

are

not

required

to

give

our

shareholders

non-binding

advisory

votes

on

executive

compensation

or

golden

parachute arrangements.

We may

continue to

take advantage

of some

or all

of the

reduced regulatory

and reporting

requirements that

will be

available to

us as

long as

we continue

to

qualify

as an

emerging

growth

company.

We

will remain

an emerging

growth

company until the

earliest to occur

of (i) the

last day of

the first fiscal

year in which

our annual gross

revenues exceed $1.235

billion, (ii) the date that the market value of our Class A common

stock that is held by non-affiliates exceeds $700 million as

of the last business day

in June of that year,

(iii) the date on which

we have, during the

previous three-year period, issued

more than $1 billion in non-convertible debt,

or (iv) the end of fiscal year following the fifth

anniversary of the completion of

our IPO (which will be December 31, 2026).

It is possible

that some

investors may

find our Class

A common stock

less attractive

since we chose

to rely

on these

exemptions. If some investors find our Class A common

stock less attractive, there may be a less

active trading market for

our Class A common stock and our stock price may be

more volatile.

Because we have elected

to use the extended

transition period for complying

with new or revised

accounting

standards for an “emerging growth company,” our financial statements may not be comparable to companies that

comply with these accounting standards as of the

public company effective dates.

As an emerging

growth company,

we elected to

use the extended

transition period

for complying

with new

or revised

accounting standards under Section 7(a)(2)(B) of the Securities Act. This election allows us to delay the adoption of new or

revised accounting standards

that have different

effective dates for

public and private

companies until those

standards apply

to private companies. As a

result of this election, our

financial statements may not be

comparable to companies that comply

with these

accounting standards

as of

the public

company effective

dates. Because

our financial

statements

may not

be

comparable

to

companies

that

comply

with

public

company

effective

dates,

investors

may

have

difficulty

evaluating

or

comparing our

business, performance

or prospects

in comparison to

other public

companies, which

may have a

negative

impact on the value and liquidity of our Class A common stock. We cannot predict if investors will find our Class A common

stock

less

attractive

because

we

have

relied

on

this

exemption.

If

some

investors

find

our

Class

A

common

stock

less

attractive as a result, there

may be a less active trading

market for our Class A common

stock and our stock price

may be

more volatile.

We have existing investors that own

a significant amount of our

common stock whose individual interests may

differ from yours.

A significant percentage of our Class A common stock is currently held by a few institutional investors, including Patriot

Financial Partners II,

L.P.

and Patriot Financial

Partners Parallel II, L.P.

(collectively,

"Patriot"), and Priam

Capital Fund II,

LP

("Priam,"

and

together

with

Patriot,

the

"Significant

Investors").

As

of

February

29,

2024

Patriot

and

Priam

own

approximately 22.82% and 22.83%,

respectively,

of our outstanding Class A

common stock. In addition,

Patriot and Priam

are each entitled to nominate a director to our Board and have certain subscription rights to purchase new equity securities

Table of Contents

43

USCB Financial Holdings, Inc.

2023 10-K

that we issue

in the future,

in each case

as long as

certain equity ownership

criteria are met.

Patriot and Priam

also have

certain

registration

rights,

including

demand

registration

rights,

and

information

rights.

Although

Patriot

and

Priam

are

independent of each other, these institutional investors will continue to have a significant level of influence over us

because

of their level of

Class A common

stock ownership and

their right to representation

on our Board. For

example, Patriot and

Priam will have a greater ability than our other shareholders to influence the election of directors and the potential outcome

of other matters submitted

to a vote of

our shareholders, including mergers and

other acquisition transactions, amendments

to our

amended Articles

of Incorporation

and Amended

and Restated

Bylaws, and

other extraordinary

corporate matters.

The interests of these investors

could conflict with the interests of our

other shareholders, and any future transfer

by these

investors of their shares

of Class A

common stock to other

investors who have different

business objectives could adversely

affect our business, results of operations, financial condition,

prospects or the market value of our Class A common

stock.

Provisions

in

our

governing

documents

and

Florida

law

may

have

an

anti-takeover

effect

and

there

are

substantial regulatory limitations on changes of control

of the Company.

Our corporate organizational documents and provisions of federal

and state law to which we

are subject contain certain

provisions that could

have an anti-takeover

effect and

may delay,

make more difficult

or prevent an

attempted acquisition

that you may favor or an attempted replacement of our

Board or management.

Our governing documents include provisions that:

empower our Board, without shareholder approval, to issue shares of preferred stock, the terms of

which, including

voting power, are set by our

Board;

provide that directors may be removed from office only for cause and only upon a majority vote

of the shares of our

Company with voting power;

prohibit holders of our Class A common stock to take action

by written consent in lieu of a shareholder meeting;

require holders of at least 10% of our Class A common

stock to call a special meeting;

do not provide for cumulative voting in elections of our

directors;

provide that

our Board

has the

authority to amend

our Amended

and Restated Bylaws

without shareholder approval;

require shareholders that wish to bring business before annual or special meetings of shareholders, or to nominate

candidates for election as directors at our annual meeting of shareholders, to provide

timely notice of their intent in

writing and satisfy disclosure requirements; and

enable our Board to increase, between

annual meetings, the number of

persons serving as directors and

to fill the

vacancies created

as a

result of

the increase until

the next

meeting of

shareholders by a

majority vote

of the

directors

present at a meeting of directors.

In addition,

certain provisions

of Florida

law may

delay,

discourage, or

prevent an

attempted acquisition

or change

in

control. Furthermore,

banking laws

impose notice,

approval, and

ongoing regulatory

requirements on

any shareholder

or

other party that seeks to acquire direct or indirect "control" of a

bank holding company,

which includes the Change in Bank

Control Act

and the

Bank Holding

Company Act.

These laws

could delay

or prevent

an acquisition.

Also, for

preservation

and continued

availability of

our "deferred

tax assets,"

our Articles of

Incorporation prohibits

any direct or

indirect transfer

of stock or options

to acquire stock

to any person

who, as a

result of the

transfer,

would own 4.95%

or more of

our stock,

as long as we continue

to have "deferred tax

assets," subject to limited

exceptions as provided in

our amended Articles

of

Incorporation.

Because

of

the

requirements

to

overcome

this

restriction,

this

provision

of

the

amended

Articles

of

Incorporation could

have an

anti-takeover effect

and

may delay,

make more

difficult

or prevent

an attempted

acquisition

that you may favor.

Risk Management and Strategy Overview

Customers

depend

on

the

Company

to

properly

protect

nonpublic

personal

information

gathered

and

stored

in

connection with the services we provide. The Company realizes that cyber incidents can have financial, reputational,

legal,

and operational impacts that can

significantly adversely affect our customers, capital, and

earnings. Therefore, we integrate

cybersecurity processes throughout the Company as part of our enterprise-wide governance process. Regulatory agencies

are

charged

with

ensuring

the

Company’s

cybersecurity

controls

and

procedures

are

compliant

with

the

intent

of

the

cybersecurity

expectations

set

forth

by

the

Federal

Financial

Institutions

Examination

Council

(“FFIEC”).

The

FFIEC

framework offers a set of guidelines

and best practices to help

financial institutions manage and mitigate cybersecurity risks

effectively.

It focuses on ensuring the confidentiality,

integrity, and availability

of sensitive information and systems.

The Information

Security Officer

(“ISO”) is

an integral

member of

the Risk

Management and

Compliance Department

(“RMCD”) of

the Bank

and who

provides expert

counsel on

matters of

cybersecurity and

presents periodic

reports to

the

Risk Committee of our Board of Directors.

As part

of the

program, periodic

risk assessments

are performed

to determine

the Company’s

inherent and

residual

cybersecurity risk, the

maturity level of the program,

the risk of cyber

threats, and the effectiveness

of controls currently

in

practice. The

Company utilizes

the National

Institute of

Standards and

Technology

(“NIST”) Framework

and the

FFIEC’s

Cybersecurity Assessment Tool

to help management identify its risks and determine the Company’s cybersecurity posture.

Through

the

implementation

of

rigorous

procedures

and

controls,

augmented

by

ongoing

training

initiatives

for

both

management

and

staff,

the

institution

cultivates

a

safe

cybersecurity

environment.

This

approach

encompasses

diverse

methodologies

including

defense-in-depth

and

proactive

security

awareness

training

aimed

at

fortifying

the

institutions

cybersecurity controls and fostering a resilient operational

framework.

Assessment and Response to Cybersecurity Threats

It is the policy of

the Company and its

technology service providers

(“TSPs”) to ensure

they can identify,

mitigate, and

respond to

cyber-attacks involving destructive

malware and invasive

attacks such

as phishing,

ransomware, malware, DDoS

attacks, etc. This commitment aligns

with the Company’s risk

appetite, Incident Response Policy,

and Business Continuity

Plan, which incorporates business continuity planning and testing activities to enhance response and recovery capabilities.

The Company

realizes that it

faces a

variety of

risks from cyber-attacks

involving destructive malware,

including liquidity,

capital, operational,

and reputation

risks, due

to events

such as

fraud, data

loss, and

disruption of

customer

service. As

such, it

is the

policy of

the Company

to ensure

that its

risk management

processes, and

business continuity

planning address

these risks by:

Establishing

a

comprehensive

governance

program

encompassing

policies

and

procedures

to

administer

and

oversee

the

information/cybersecurity

programs

to

ensure

adherence

to

regulatory

guidance

and

industry

best

practices.

Securely configuring systems and services to mitigate the impact of cyberattacks.

This includes measures such as

logical

network

segmentation,

hard

backups,

maintaining

an

inventory

of

authorized

Properties

The Company’s corporate offices

are headquartered at 2301 N.W.

87th Avenue, Miami, Florida 33172. The

Company,

through the

Bank,

operates

10 banking

centers

in South

Florida

within

Miami-Dade

and

Broward counties.

From

the

10

banking centers, nine of these locations are leased and one is owned. The

banking center that is owned is located at 3999

Sheridan St, Hollywood, FL 33021. Management

believes that each of these locations are

in good condition and adequate

to meet our present and foreseeable needs, subject to

possible future expansion.

Item 3.

Legal Proceedings

We are not currently subject to any material legal proceedings. We are from time to time subject to claims and litigation

arising

in

the

ordinary

course

of

business.

These

claims

and

litigation

may

include,

among

other

things,

allegations

of

violation of banking and other applicable regulations, competition

law, labor laws and consumer

protection laws, as well as

claims or

litigation

relating

to intellectual

property,

securities, breach

of contract

and tort.

We

intend to

defend ourselves

vigorously against any pending or future claims and litigation.

The

Company

previously

disclosed

that

litigation

(the

“Litigation”)

had

been

commenced

on

July

13,

2023

by

three

individuals

who

were

shareholders

of

the

Bank

prior

to

the

Bank’s

reorganization

into

the

holding

company

form

of

organization in 2021

(the “Plaintiffs”)

against six

persons, all

of whom were

directors of

the Bank at

the relevant

time (the

“Defendants”), in the Circuit Court, Eleventh Judicial Circuit for Miami-Dade County, Florida (the “Court”) (Benes et al. v. de

la

Aguilera

et

al.)

alleging

the

Defendants

(i) caused

the

Bank,

as

directors

thereof,

to

engage

in ultra

vires

conduct by

devising

and

approving

the

exchange

transaction

effected

in

July

2021

pursuant

to

which

the

Bank’s

then

outstanding

shares of Class C and Class D preferred stock was exchanged for shares of Class A voting common stock in the

Bank (the

“Exchange Transaction”),

which action

the Plaintiffs

allege was

not permitted

by the

Bank’s Articles

of Incorporation,

and

(ii) breached

their

fiduciary

duty as

directors

of the

Bank

by

approving

and

engaging

in

the

Exchange

Transaction.

The

Plaintiffs sought the

Court to certify the

action as a class

action and to award

damages in an

amount to be

proven at trial.

Plaintiffs

sought

damages

exceeding

$750,000

plus

attorney’s

fees

and

costs

as

well

as

such

other

relief

as

the

Court

determined to award.

The Defendants filed a motion to dismiss the Litigation with

prejudice (the “Motion”). On December 27, 2023, the Court,

after reviewing

the Motion,

the Plaintiff’s response

thereto and

the Defendant’s reply

as well

as the

oral arguments presented

by

the

parties

on

December

14,

2023,

granted

the

Motion,

dismissing

the

Litigation

with

prejudice

and

rendering

final

judgment in favor of the Defendants. The Court reserved jurisdiction

to award costs or grant any post-judgment relief.

There can be no

assurance that any

future legal proceedings

to which we are

a party will not

be decided adversely

to

our interests and have a material adverse effect

on our financial condition and operations.

(a)

Market Information

In July

2021, the Bank’s

Class A common

stock began trading

on the

Nasdaq Stock Market

under ticker

symbol “USCB”.

The listing of our Class

A common stock on

the Nasdaq Stock Market

has resulted in a

more active trading market

for our

Class

A

common

stock.

However,

we

cannot

assure

that

a

liquid

trading

market

for

our

Class

A

common

stock

will

be

sustained.

Effective December 30, 2021, the bank holding company,

or the Company, acquired all issued and

outstanding shares

of Class

A common

stock of

the Bank.

Each of

the outstanding

shares of

the Bank’s

common stock

formerly held

by its

shareholders was converted

into and exchanged

for one newly

issued share

of the Company’s

common stock.

The ticker

symbol “USCB” remained the same.

Prior

to

our

listing

on

the

Nasdaq

Stock

Market

there

was

not

an

established

public

trading

market

for

the

Class

A

common shares. The

following table shows

the quarterly high and

low closing prices

common stock traded

As of

December 31, 2023,

our Class

B common

stock is

not listed

or traded

on any

stock exchange

and no

shares were

issued and outstanding at such date.

Holders

As

of

January

31,

2024,

the

Company’s

Class

A

common

shares

were

held

by

approximately

402

shareholders

of

record,

not including

the number

of persons

or entities

whose stock

is held

in nominee

or “street”

name through

various

brokerage firms and banks.

Dividends

As a bank holding company, the Company’s ability to declare and pay dividends depends on various federal regulatory

considerations, including the guidelines of the Federal Reserve

regarding capital adequacy and dividends.

Because we are

a bank holding

company and currently do

not engage directly in

business activities of a

material nature,

our ability to pay dividends

to our shareholders depends,

in large part, upon

our receipt of dividends

from the Bank, which

is also subject to

numerous limitations on

the payment of dividends

under federal and state

banking laws, regulations

and

policies.

The principal

source of

revenue with

which to

pay dividends

on common

shares are

dividends the

Bank may

declare

and

pay

out

of

funds

legally

available

for

payment

of

dividends.

As

a

Florida

corporation,

we

are

only

permitted

to

pay

dividends to shareholders if, after giving effect to the dividend, (i) the Company is able to pay its debts as they become due

in the ordinary course

of business and

(ii) the Company’s

assets exceeds the

sum of Company’s

(a) liabilities plus

(b) the

amount that

would be

needed for

the Company

to satisfy

the preferential

rights

upon dissolution

of shareholders

whose

preferential rights are superior to those receiving the dividend,

if any.

Non-GAAP Financial Measures

This Annual Report on Form 10-K includes

financial information determined by methods

other than in accordance with

generally

accepted

accounting

principles

(“GAAP”).

This

financial

management uses

these

measures

in

managing

and

evaluating

the

Company’s

business

and

intends

to

refer

to

them

in

Critical Accounting Policies and Estimates

The

consolidated

financial

statements

are

prepared

based

on

the

application

of

U.S.

GAAP,

the

most

significant

of

which are described

in Note 1 “Summary

of Significant Accounting

Policies” to our

Consolidated Financial Statements.

To

prepare financial statements in conformity with GAAP,

management makes estimates, assumptions,

and judgments based

on

available

information.

These

estimates,

assumptions,

and

judgments

affect

the

amounts

reported

in

the

financial

statements and accompanying notes. These estimates, assumptions, and judgments are based on

information available as

of

the

date

of

the

financial

statements

and,

as

this

information

changes,

actual

results

could

differ

from

the

estimates,

assumptions

and

judgments

reflected

in

the

financial

statements.

In

particular,

management

has

identified

accounting

policies that, due to

the estimates, assumptions

and judgments inherent

in those policies, are

critical in understanding

our

financial statements.

Management

has presented

the application

of these

policies

to the

audit and

risk committee

of our

Board.

Allowance for Credit Losses - Loans

The allowance for credit

losses (“ACL”) is

a valuation allowance that

is established through charges

to earnings in the

form of

a provision for

credit losses. The

amount of the

ACL is

affected by the

following: (i) charge-offs

of loans that

decrease

the allowance;

(ii) subsequent

recoveries on

loans previously

charged off

that increase

the allowance;

and (iii)

provisions

for credit losses charged to income that increase or decrease the allowance. Management considers the policies related to

the ACL as the most critical to the financial statement presentation.

Financial

Instruments

-

Credit

Losses

(Topic

326):

Measurement of Credit Losses on Financial Instruments, as amended. This update replaces the incurred

loss methodology

with

the

CECL

methodology.

The

CECL

methodology

measures

expected

credit

losses

and

applies

to

financial

assets

measured at

amortized cost,

including loan

receivables and

held-to-maturity debt

securities. It

also applies

to off-balance

sheet

credit

exposures

not

accounted

for

as

insurance

(e.g.,

loan

commitments,

standby

letters

of

credit,

financial

guarantees, and similar instruments), as

well as net investments in leases

recognized by lessors in accordance

with Topic

842 on leases.

Under CECL, the Company estimates the allowance for credit losses by utilizing pertinent available data, sourced both

internally and

externally,

relating to

past events,

current conditions,

and reasonable

and supportable

forecasts. Historical

credit

losses

provide

the

foundation

for

estimation

of

expected

credit

losses.

Qualitative

adjustments

are

applied

to

the

estimated

expected

credit

losses

for

the

loan

portfolio

to

account

for

potential

constraints

of

the

quantitative

model.

Management

employs

a

scorecard

to

facilitate

the

evaluation

of

qualitative

factor

adjustments

made

to

expected

credit

losses.

The estimation's

quantitative aspect

relies on

the statistical

correlation between

the anticipated

value of

an economic

indicator and the

historical loss

experience implied

within a

selected group

of peers.

The Company conducted

regression

analyses using

peer data,

inclusive of

the Company

itself, where

observed credit

losses and chosen

economic indicators

were utilized to identify

appropriate drivers for

modeling the lifetime

probability of default (“PD”)

rates. A loss given

default

rate (“LGD”) is assigned to each pool

of loans for each period based on

these PD outcomes. The model

primarily employs

an expected

discounted cash

flow (“DCF”)

analysis for

segments within

the loan

portfolio. This

DCF analysis

operates at

the

individual

instrument

level

and

incorporates

various

loan-specific

data

points

and

segment-specific

assumptions

to

ascertain the lifetime expected

loss associated with each

instrument. An implicit "hypothetical

loss" is determined for

each

period of the DCF,

aiding in establishing the

present value of future

cash flows for each

period. The reserve allocated

to a

particular loan represents the disparity

between the sum of the

present value of future cash

flows and the book balance

of

the loan at the measurement date.

Management opted for the Remaining Life (“WARM”) methodology for five segments within the loan portfolio. For each

segment,

a

long-term

average

loss

rate

is

computed

and

applied

quarterly

throughout

the

remaining

life

of

the

pool.

Qualitative assessments

are conducted

to adjust for

economic expectations.

To

estimate the remaining

life, management

employed a software solution utilizing an attrition-based calculation. This software conducts quarterly cohort-based attrition

measurements based on the loan portfolio.

Portfolio

segments

represent

the

level

at

which

loss

assumptions

are

applied

to

a

pool of

loans,

determined

by

the

similarity of

risk characteristics inherent

in the

included instruments, based

on collateral

codes and

FFIEC Call Report

codes.

Currently,

the Company segments

the portfolio based on

collateral codes to establish

reserves. Each segment

is linked to

regression

models

(Loss

Driver

Analyses)

using

peer

data

for

loans

with

similar

risk

characteristics.

The

Company

has

established connections between

internal segmentation and

FFIEC Call Report

codes for this purpose.

The loss driver

for

each

loan

portfolio

segment

is

derived

from

a

readily

available

and

reasonable

economic

forecast,

including

Federal

Reserve Bank projections

of the U.S.

civilian unemployment

rate and year-over-year

real GDP growth.

For the residential

loan segment, House Price

Index (“HPI”) projections published

by Fannie Mae’s

Economic and Strategic Research

Group

are utilized for

the forecast. Forecasts are

applied for the

first four quarters

of the credit

loss estimate and

then linearly revert

to the historical mean of the economic indicator over the expected

life of the loans.

The model integrates qualitative

factor adjustments to

fine-tune risk calibration

for each portfolio

segment, addressing

aspects that quantitative analysis may

not fully capture. Decisions concerning

qualitative adjustments reflect management's

anticipation of loss conditions deviating from those already accounted

for in the quantitative aspect of the model.

Our ACL

included residential

loans. To

assess the

potential impact

of changes

in qualitative

factors related

to these

loans,

management

performed

a sensitivity

analysis.

The Company

evaluated

the

impact

of the

HPI

used

in calculating

expected losses on the residential loan segment.

As of December 31, 2023, for every

100 basis points increase in the HPI

index, the forecast reduces

reserves by approximately $150

thousand and about 1

basis point to

the reserve coverage ratio,

everything else being

constant. This

sensitivity analysis provides

a hypothetical result

to assess the

sensitivity of the

ACL

and does not represent a change in management’s

judgement.

As of December

31, 2023,

we stress

tested two

qualitative factors

in our commercial

real estate

loan pool,

as it’s

the

largest segment

in our

portfolio. We

evaluated the

impact of

a change

in the

qualitative factors

from no

risk to

maximum

loss

to measure

the

sensitivity

of the

qualitative

factors.

The change

resulted

in

a $6.1

million

or

32.6%

increase

in the

allowance for credit losses.

This sensitivity analysis

provides a hypothetical result

to assess the sensitivity

of the ACL and

does not represent a change in management’s judgement.

The Company calculates a reserve for unfunded commitments, distinct from

the allowance for credit losses reported in

other liabilities.

This reserve

is determined

using both

quantitative and

qualitative factors

identical to

those applied

to the

collectively evaluated loan portfolio.

Income Taxes

Deferred tax

assets and

liabilities are

recognized for

the future

tax consequences

attributable to

differences

between

the financial statement carrying amounts of

existing assets and liabilities and their

respective tax bases and operating loss

and tax credit carryforwards. Deferred tax

assets and liabilities are measured

using enacted tax rates expected

to apply to

taxable income

in the

years in

which those

temporary differences

are expected

to be

recovered or

settled. The

effect

on

deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment

date.

Management is required to assess whether a valuation allowance should be established on the net deferred tax assets

based on the

consideration of

all available evidence

using a more

likely than not

standard. In its

evaluation, management

considers taxable loss

carry-back availability, expectation of sufficient

taxable income, trends

in earnings, the

future reversal

of temporary differences, and available tax planning

strategies.

The Company recognizes positions taken

or expected to be

taken in a tax

return in accordance with existing accounting

guidance on

income taxes

which prescribes

a recognition threshold

and measurement

process. Interest

and penalties

on

tax liabilities, if any, would

be recorded in interest expense and other operating non-interest

expense, respectively.

Segment Reporting

Management monitors the revenue streams for all its various

products and services. The identifiable segments are not

material

and

operations

are

managed

and

financial

performance

is

evaluated

on

an

overall

Company-wide

basis.

Accordingly, all

the financial service

operations are

considered by management

to be

aggregated in one

reportable operating

segment.

The Company’s results

of operations

depend substantially on

net interest income

and non-interest income.

Other factors

contributing to the

results of operations

include our provision

for credit losses,

non-interest expense, and

the provision for

income taxes.

Net income

for the

year ended

December 31, 2023

was $16.5 million

,

compared with

net income

of $20.1 million

for

the same

period in

  1. The Company

reported net

income per

diluted share

for the

year ended

December 31, 2023

of

$0.84 compared to net income per diluted share for the

same period in 2022 of $1.00.

Net Interest Income

Net

interest

income

is

the

difference

between

interest

earned

on

interest-earning

assets

and

interest

incurred

on

interest-bearing liabilities and

is the

primary driver of

core earnings. Interest

income is generated

from interest and

dividends

on

interest-earning

assets,

including

loans,

investment

securities

and

other

short-term

investments.

Interest

expense

is

incurred

from

interest

paid

on

interest-bearing

liabilities,

including

interest-bearing

deposits,

FHLB

advances

and

other

borrowings.

To evaluate net

interest income, we

measure and monitor

(i) yields on

loans and other

interest-earning assets, (ii)

the

costs of deposits

and other funding

sources, (iii) net

interest spread, and

(iv) net interest margin.

Net interest spread is

equal

to the difference

between the weighted

average yields

earned on interest

-earning assets

and the weighted

average rates

paid on

interest-bearing

liabilities. Net

interest margin

is equal

to the

annualized

net interest

income

divided by

average

interest-earning

assets.

Because

non-interest-bearing

sources

of

funds,

such

as

non-interest-bearing

deposits

and

stockholders’ equity, also fund

interest-earning assets, net interest margin includes

the benefit of these

non-interest-bearing

sources.

Changes in

the market

interest rates

and interest

rates we

earn on

interest-earning assets

or pay on

interest-bearing

liabilities, as well

as the volume

and types of

interest-earning assets and interest-bearing

and non-interest-bearing liabilities,

are usually the

largest drivers of

periodic changes in

net interest spread,

net interest margin

and net interest

income. The

Asset-Liability Committee (“ALCO”) has in place asset-liability management techniques to manage major factors that affect

net interest income and net interest margin.

Net interest

income before

the provision

for credit

losses was

$58.6 million for

the year

ended December 31,

2023, a

decrease of

$5.1 million or

8.0%, from

$63.7 million for

the year

ended December 31,

  1. This

decrease was

primarily

attributable to higher

cost of funds

due to the interest

rate market.

The increase in

weighted average rates

paid on cost of

funds was greater than the increase in weighted average yields

earned on interest-earning assets.

The net

interest margin was

2.79% for

the year ended

December 31, 2023 and

3.38%

for the

year ended 2022.

Although

the overall

and individual

yields for

interest-earning assets

and interest-bearing

liabilities both

increased in

2023, cost

of

funds had a

greater increase

when compared

to 2022. The

increase in

our cost of

funds was primarily

due to the

interest

rate market.

Provision for Credit Losses

ACL represents expected

credit losses

in our

portfolio as

the measurement

date. We

maintain an

adequate ACL that

can

mitigate

expected

credit

losses

in

the

loan

portfolio.

The ACL

is

increased

by

the

provision

for

credit

losses

and

is

decreased by charge-offs, net

of recoveries on prior

loan charge-offs. There are

multiple credit quality metrics

that we use

to base

our determination

of the

amount

of the

ACL and

corresponding

provision

for credit

losses. These

credit metrics

evaluate the

credit quality

and level

of credit

risk inherent

in our

loan portfolio,

assess

non-performing loans

and charge-

offs levels, considers statistical trends and economic conditions

and other applicable factors.

Provision for credit loss for

the year ended December 31, 2023,

was $2.4 million compared to

$2.5 million in provision

expense for the same period in 2022. The ACL as a percentage of total loans was 1.18% at December 31, 2023 compared

to 1.16% at December 31, 2022.

Non-Interest Income

Net interest income

and other types of

recurring non-interest

income are generated

from our operations.

Our services

and products generate service charges and fees, mainly from our depository accounts. We also

generate income from gain

on sale of loans though our swap and SBA programs. In addition, we own life insurance policies on several employees and

generate income reflecting the increase in the cash surrender value

of these policies.

fees. Additionally, in

both 2023 and 2022, the

Company executed a portfolio restructuring strategy

which resulted in the sale

of lower-yielding available-for-sale securities at a loss in

order to better position our securities portfolio.

Non-interest expense

for the

year ended

December 31, 2023

increased $2.5 million

or 6.4%,

compared to

the same

period in 2022. The increase is

primarily due to other operating expense specially in

the categories of internet banking fees,

promotional expense, audit

and tax

service fees, and

insurance expense due

to increased

activity and fees,

which increased

$1.1 million or 19.7%. Regulatory assessment and fees increased by $523 thousand

or 56.2% compared to the year ended

  1. Salaries and benefits increased by $486 thousand or 2.0%

due to increase in full time employees to 196 from 191

in

  1. The increase

in salaries and

employee benefits

and other operating

costs has

enabled us to

support recent

growth

and has provided us with the necessary technology and

required professionals to execute our growth strategy.

Provision for Income Tax

Fluctuations in the effective tax rate reflect the effect of the differences in the inclusion or deductibility of certain income

and expense for income tax purposes.

Therefore, future decisions on the investments we

choose will affect our effective tax

rate. Changes in the

cash surrender value

of bank-owned life

insurance policies for

key employees, purchasing

municipal

bonds, and overall taxable income will be important elements

in determining our effective tax rate.

Income tax

expense for

the year

ended

December 31,

2023 was

$5.3 million,

compared

to $6.9

million

for the

year

ended December 31, 2022. The

effective tax rate for

the year ended December 31, 2023

was 24.1% and for the

year ended

December 31, 2022 was 25.6%.

Investment Securities

The investment portfolio

is used and

managed to provide

liquidity through cash

flows, marketability

and, if necessary,

collateral for

borrowings. The

investment portfolio

is also

used as

a tool

to manage

interest rate

risk and

the Company’s

capital market risk exposure. The

operating philosophy of the portfolio is

to maximize the Company’s profitability,

taking into

consideration the

Company’s risk

appetite and

tolerance, manage

it’s asset

composition and

diversification, and

maintain

adequate risk-based capital ratios.

The

investment

portfolio

is

managed

in

accordance

with

the

Asset

and

Liability

Management

(“ALM”)

policy,

which

includes an

investment guideline,

approved by

the Board.

Such policy

is reviewed

at least

annually or

more frequently

if

deemed necessary,

depending on

market

conditions

and/or

unexpected

events.

The investment

portfolio

composition

is

subject

to

change

depending

on

the

funding

and

liquidity

needs

of

the

Company,

and

the

interest

risk

management

objectives directed by the ALCO. The portfolio of investments can be used to modify the duration of the balance sheet.

The

allocation of cash into securities takes into consideration anticipated

future cash flows (uses and sources) and all available

sources of credit.

Our

investment

portfolio

consists

primarily

of

securities

issued

by

U.S.

government-sponsored

agencies,

agency

mortgage-backed securities,

collateralized mortgage

obligation securities,

municipal securities,

and other

debt securities,

all with varying contractual maturities and coupons. Due to the optionality embedded in these securities, the final maturities

do not

necessarily represent the

expected life of

the portfolio. Some

of these

securities will be

called or paid

down depending

on capital market conditions and expectations. The investment portfolio is regularly reviewed by the Chief Financial Officer,

Treasurer, and/or the ALCO of the Company to ensure an appropriate risk and return profile as

well as for adherence to the

Company’s investment policy.

As of December 31, 2023, the investment portfolio consisted of available-for-sale

(“AFS”) and held-to-maturity (“HTM”)

debt

securities.

During

the

third

quarter

of

2022,

26

investment

securities

were

transferred

from

AFS

to

HTM

with

an

amortized cost basis

and fair value

amount of $74.4

million and $63.8

million, respectively.

On the date

of transfer,

these

securities had a total net unrealized loss of $10.6 million. The transfer of the debt securities

from the AFS to HTM category

was made at fair value at the date of transfer.

The unrealized gain or loss at the date of transfer is retained

in accumulated

other comprehensive income (loss)

and in the carrying value

of the HTM securities.

Such amounts are amortized

over the

remaining life

of the

security. There was no

impact to

net income on

the date of

transfer. There were no

securities transferred

from AFS to HTM in 2023.

The book value of the AFS securities is adjusted quarterly for

unrealized gain or loss as a valuation allowance, and any

gain or loss is reported on an after-tax basis as a component of other comprehensive income (loss) in stockholders’ equity.

CECL requires

a loss reserve

for securities

classified as

Held-to-Maturity (HTM).

The reserve should

reflect historical

credit performance

as well

as the

impact of

projected

economic forecast.

For U.S.

Government bonds

and

U.S. Agency

issued bonds in HTM the explicit guarantee

of the US Government is sufficient

to conclude that a credit loss reserve

is not

required. The reserve

requirement is for

three primary assets

groups: municipal bonds,

corporate bonds, and

non-agency

securitizations.

The

Company

calculates

quarterly

the

loss

reserve

utilizing

Moody’s

ImpairmentStudio.

The

CECL

measurement

for

investment

securities

incorporates

historical

data,

containing

defaults

and

recoveries

information,

and

Moody’s baseline

economic forecast.

The solution

uses probability

of default/loss

given default (“PD/LGD”)

approach. PD

represents the likelihood a borrower will

default. Within the Moody’s model,

this is determined using historical

default data,

adjusted for the current economic environment. LGD projects

the expected loss if a borrower were to default.

The Company

monitors the credit

quality of HTM

securities through the

use of

credit ratings. Credit

ratings are monitored

by the Company

on at least

a quarterly basis.

As of December

31, 2023 and

December 31, 2022,

all HTM securities

held

by the Company were rated investment grade.

At year ended

December 31, 2023,

HTM securities included $165.6

million of U.S.

Government and U.S.

Agency issued

bonds and

mortgage-backed

securities.

Because

of the

explicit and/or

implicit

guarantee

on these

bonds,

the

Company

holds no reserves

on these

holdings. The

remaining portion

of the HTM

portfolio is

made up of

$9.4 million

in investment

grade

corporate

bonds.

The

required

reserve

for

these

holdings

is

determined

each

quarter

using

the

model

described

above. For the portion of the HTM

exposed to non-government credit risk,

the Company utilized the PD/LGD

methodology

to estimate a $8 thousand ACL as of December 31,

  1. The book value for debt securities classified

as HTM represents

amortized cost less ACL.

AFS and HTM

investment securities

in aggregate

decreased $14.5 million

or 3.5%

to $404.3 million

at December 31,

2023 from $418.8

million at

December 31, 2022.

Investment securities

decreased over the

past year as

repayments from

securities were

allocated to

fund loan

growth.

Management reinvested

the repayments

of securities

and income

from the

sale of securities into higher

yielding loans. As of December

31, 2023, securities with

a market value of $86.9

million were

pledged to secure public deposits and $132.1 million pledged in securities measured at par to the Federal Reserve Bank of

Atlanta

for

the

BTFP

program.

As

of

December 31,

2023,

the

Company

did

not

have

any

tax-exempt

securities

in

the

portfolio.

Loans

Loans are

the largest

category of

interest-earning assets

on the

Consolidated

Balance Sheets,

and usually

provides

higher yields than the remainder of the Company’s

in accordance with

compared to December

31, 2022. The

most significant growth

was in the

commercial and

industrial and

commercial real

estate loan pools.

Consumer and

other

loans increased primarily as result of organic growth from our yacht lending business vertical created in January 2022. Our

loan

portfolio

continues

to

diversify

as

commercial

and

industrial

and

consumer

loans,

mostly

yacht

loans,

continue

to

increase as a percentage to

total loans. However,

we do not expect any

significant changes over the

foreseeable future in

the composition of our loan portfolio. Commercial real estate continues to be the main category of our portfolio, reflective of

the market in which we operate.

The

growth

experienced

over

the

last

couple

of

years

is

primarily

due

to

implementation

of

our

relationship-based

banking

model,

our

diversified

business

verticals,

and

the

success

of

our

relationship

managers

in

competing

for

new

business in a highly competitive metropolitan area. Many of

our larger loan clients have lengthy relationships with members

of our senior management team or our relationship managers

that date back to former institutions.

us with

The information

presented

in the

table above

is based

upon the

contractual

maturities of

the individual

loans, which

may be

subject to

renewal at

their contractual

maturity.

Renewals will

depend on

approval by

our credit

department and

balance sheet

composition at the

time of

the analysis,

as well

as any

modification of terms

at the

loan’s maturity. Additionally,

maturity

concentrations,

loan

duration,

prepayment

speeds

and

other

interest

rate

sensitivity

measures

are

discussed,

reviewed, and analyzed by the ALCO. Decisions on term

rate modifications are discussed as well.

As of

December 31,

2023, approximately

57.9%

of the

loans

have adjustable/variable

rates

and

42.1%

of the

loans

have fixed rates.

The adjustable/variable

loans re-price to

different benchmarks

and tenors in

different periods

of time. By

contractual characteristics, there are no

material concentrations on anniversary repricing. Additionally, it is

important to note

that most

of our

loans have

interest rate

floors. This

embedded option

protects the

Company from

a decrease

in interest

rates and positions us to gain in the scenario of higher interest

rates.

Asset Quality

Our asset quality grading

analysis estimates the capability of

the borrower to repay

the contractual obligation of

the loan

agreement as scheduled or at all. The Company’s internal credit risk grading system is based on experiences with similarly

graded loans. Internal

credit risk

grades are evaluated

at least annually,

or more frequently

if deemed necessary.

Internal

credit

risk

ratings

may

change

based

on

management’s

assessment

of

the

results

from

the

annual

review,

portfolio

monitoring and other developments observed with borrowers.

The internal credit risk grades used by the Company to

assess the credit worthiness of a loan are shown below:

Pass

– Loans indicate different levels of satisfactory

financial condition and performance.

Table of Contents

63

USCB Financial Holdings, Inc.

2023 10-K

Special Mention

– Loans classified as special mention have a potential weakness

that deserves management’s

close attention. If left uncorrected, these potential weaknesses

may result in deterioration of the repayment

prospects for the loan or of the institution’s

credit position at some future date.

Substandard

– Loans classified as substandard are inadequately protected

by the current net worth and paying

capacity of the obligator or of the collateral pledged, if

any. Loans so classified

have a well-defined weakness or

weaknesses that jeopardize the liquidation of the debt.

They are characterized by the distinct possibility that the

institution will sustain some loss if the deficiencies are

not corrected.

Doubtful

– Loans classified as doubtful have all the weaknesses inherent

in those classified at substandard, with

the added characteristic that the weaknesses make collection

or liquidation in full on the basis of currently existing

facts, conditions, and values, highly questionable and improbable.

Loss

– Loans classified as loss are considered uncollectible.

Non-performing

assets

include

all

loans

categorized

as non-accrual

or restructured,

impaired

securities,

OREO

and

other repossessed assets. Problem loans for which the collection or liquidation in full is reasonably uncertain are placed on

a

non-accrual

status.

This

determination

is

based

on

current

existing

facts

concerning

collateral

values

and

the

paying

capacity of the borrower. When the collection of the full contractual balance is unlikely,

the loan is placed on non-accrual to

avoid overstating the Company’s income for a

loan with increased credit risk.

If the

principal or

interest on

a commercial

loan becomes

due and

unpaid for

90 days

or more,

the loan

is placed

on

non-accrual status as of

the date it becomes

90 days past due

and remains in non-accrual

status until it meets

the criteria

for restoration to accrual status.

Residential loans, on

the other hand, are placed

on non-accrual status when

the principal

or interest

becomes due

and unpaid

for 120

days or

more and remains

in non-accrual

status until

it meets

the criteria

for

restoration

to

principal and interest

payments for a period

of six months

and the Company

has a documented

expectation of repayment

of the remaining contractual principal and interest or the

loan becomes secured and in the process of collection.

The

Company

may

grant

a

concession

to

a

borrower

experiencing

financial

difficulties.

This

determination

is

performed during

the annual

review process

or whenever

problems are

surfacing regarding

the client’s

ability to

repay in

accordance with

the original

terms of

or line

of credit.

The concessions

are given

to the

debtor in

various forms,

including interest rate

reductions, principal forgiveness, extension

concessions intended to minimize potential losses.

Annual Report on Form 10-K.

Allowance for Credit Losses

On January 1,

2023, the Company

adopted FASB ASU 2016-13, which

introduced the CECL methodology

and required

us to

estimate all

expected credit

losses over

the remaining

life of

our loan

portfolio. Accordingly,

the ACL

represents an

amount

that,

in

management's

evaluation,

is

adequate

to

provide

coverage

for

all

expected

future

credit

losses

on

outstanding loans as of the

measurement date. Additionally,

qualitative adjustments are made to

the ACL when, based on

management’s judgment, there

are factors impacting

the allowance estimate

not considered by

the quantitative calculations.

Deposits

Customer deposits are the

primary funding source for

the Bank’s growth.

Through our network of

banking centers, we

offer a competitive array of deposit

accounts and treasury management services designed

to meet our customers’ business

needs. Our primary

deposit customers

are SMBs,

and the personal

business of owners

and operators

of these SMBs,

as

well as the retail/consumer relationships of the employees

of these businesses. Our focus on quality and customer

service

has created a strong brand recognition within

our depositors, which reflects in the composition

of our deposits; most of our

funding sources

are core

deposits. In

addition to

our banking

centers

network, we

have developed

business

verticals to

diversify our portfolio in

different specialty

industries and we offer

public fund deposit

products to municipalities

and public

agencies in our geographical footprint.

Furthermore, our

personal and

private banking

management

line of

business is

focused on

the needs

of the

owners

and operators of

our business customers,

offering a suite

of checking, savings,

money market and

time deposit accounts,

and utilizing superior

client service

to build and

expand client relationships.

A unique aspect

of our business

model is our

ability to offer correspondent services to banks in

Central America and the Caribbean.

totaled

$58.1

Critical elements of our liquidity

risk management include: effective corporate governance consisting of

oversight by the

Board and ALCO and

involvement by senior management;

appropriate strategies, policies,

procedures, and limits

used to

identify

and

mitigate

liquidity

risk;

comprehensive

liquidity

risk

measurement

and

monitoring

systems

(including

assessments

of

the

current

prospective

cash

flows

or

sources

and

uses

of

funds)

that

are

commensurate

with

the

complexity and business

activities of the

Company; management of intraday

liquidity and collateral;

an appropriately diverse

mix

of

existing

potential

funding

sources;

adequate

levels

marketable

securities

free

of

comprehensive

funding

plans

that

sufficiently

address

potential

adverse

events

and

emergency

cash

flow

requirements;

and

internal

controls and

internal

audit

processes

sufficient

to

determine

the

adequacy

of

the

institution’s

liquidity risk management process.

We

expect

funds

to

be

available

from

several

basic

banking

activity

sources,

including

the

core

deposit

base,

the

repayment and maturity of loans and investment security

cash flows. Other potential funding sources include

federal funds

purchased, brokered

certificates

of deposit,

listing certificates

of deposit,

Fed funds

lines and

borrowings from

the FHLB

Atlanta. Accordingly, our liquidity resources were at sufficient levels to

fund loans and meet other

cash needs as necessary.

Off-Balance Sheet Arrangements

We engage

in various financial

transactions in

our operations

that, under GAAP,

may not be

included on

the balance

sheet. To

meet the financing needs

of our customers we may

include commitments to extend

credit and standby letters

of

credit. To

a varying

degree, such

commitments involve

elements of

credit, market,

and interest

rate risk

in excess

of the

amount recognized

in the

balance sheet.

We use

more conservative

credit and

collateral policies

in making

these credit

commitments as we

do for on-balance sheet

items. We are not

aware of any accounting

loss to be

incurred by funding

these

commitments; however,

we maintain an allowance

for off-balance sheet

credit risk which is

recorded under other liabilities

on the Consolidated Balance Sheets.

Since commitments associated with letters of

credit and commitments to extend

credit may expire unused, the

amounts

shown do not necessarily

reflect the actual

future cash funding requirements

.

Commitments to extend credit are agreements to lend funds to a client, as long as there is no violation of any condition

established

in

the

contract,

for

a

specific

purpose.

Commitments

generally

have

variable

interest

rates,

fixed

expiration

dates or

other

termination

clauses

and

may require

payment

of

a fee.

Since many

of the

commitments

are

expected to

expire without being

fully drawn, the

total commitment

amounts disclosed

above do not

necessarily represent

future cash

requirements.

Unfunded lines of credit represent unused portions of credit facilities to our current borrowers that represent no change

in credit risk in our portfolio. Lines of credit

generally have variable interest rates. The

maximum potential number of future

payments we could

be required to

make is represented

by the contractual

amount of the

commitment, less

the amount of

any advances made.

Letters of credit are

conditional commitments issued

by us to guarantee

the performance of a

client to a third

party.

In

the event of nonperformance by

the client in accordance with the

terms of the agreement with the

third party,

we would be

required to fund

the commitment.

If the commitment

is funded, we

would be entitled

to seek recovery

from the client

from

the underlying collateral,

which can include

commercial real estate,

physical plant and

property, inventory, receivables, cash

or marketable securities.

Asset and Liability Management Committee

The asset and liability management committee of our Company, or ALCO, consists of members of senior management

and our Board. Senior management is responsible for

ensuring in a timely manner that Board

approved strategies, policies,

and procedures

for managing

and mitigating

risks are

appropriately executed

within the

designated lines

of authority

and

responsibility.

ALCO

oversees

the

establishment,

approval,

implementation,

and

review

of

interest

rate

risk,

management,

and

mitigation strategies, ALM related policies, ALCO procedures

and risk tolerances and appetite.

While some degree of interest

rate risk (“IRR”) exposure is inherent

to the banking business, our ALCO

has established

sound risk management practices in place to identify,

measure, monitor and mitigate IRR exposures.

When assessing the scope

of IRR exposure and

impact on the consolidated

balance sheet, cash flows

and statement

of operations,

management considers

both earnings

and economic

impacts. Asset price

variations, deposits

volatility and

reduced earnings or outright losses could adversely affect

the Company’s liquidity,

performance, and capital adequacy.

Income simulations

are used

to assess

the impact

of changing

rates on

earnings under

different rates

scenarios and

time horizons.

These simulations

utilize both

instantaneous and

parallel changes

in the

level of

interest rates,

as well

as

non-parallel changes such as changing slopes (flat and steeping) and

twists of the yield curve, Static simulation models are

based on current exposures and

assume a constant balance sheet with

no new growth. Dynamic simulation analysis

is also

utilized to have a

more comprehensive assessment

on IRR. This simulation

relies on detailed

assumptions outlined in

our

budget and strategic plan, and in assumptions regarding changes in

existing lines of business, new business, management

strategies and client expected behavior.

To

have

a

more

complete

picture

of

IRR,

the

Company

also

evaluates

the

economic

value

of

equity,

or

EVE.

This

assessment

allows

us

to

measure

the

degree

to

which

the

economic

values

will

change

under

different

interest

rate

scenarios. The economic value of equity approach focuses on

a longer-term time horizon and captures all

future cash flows

expected from existing assets and liabilities.

The economic value model utilizes a

static approach in that the analysis does

not incorporate new business; rather,

the analysis shows a snapshot in time of the risk

inherent in the balance sheet.

Market and Interest Rate Risk Management

According to our ALCO model, as

of December 31, 2023, we were

a slightly asset sensitive/neutral bank

for year one

modeling and asset sensitive for year two modeling. Asset sensitivity indicates that

our assets generally reprice faster than

our

liabilities,

which

results

in

a

favorable

impact

to

net

interest

income

when

market

interest

rates

increase.

Liability

sensitivity indicates

that our

liabilities generally

reprice faster

than

our assets,

which results

in a

favorable

impact to

net

interest income

when market

interest rates

decrease. Many

assumptions are

used to

calculate the

impact of

interest rate

variations

on

our

net

interest

income,

such

as

asset

prepayment

speeds,

non-maturity

deposit

price

sensitivity,

pricing

correlations, deposit truncations and decay rates, and

key interest rate drivers.

Because of the inherent use

of these estimates and

assumptions in the model,

our actual results may,

and most likely

will, differ from static measures results. In

addition, static measures like the economic value

of equity (“EVE“) do not include

actions that management may undertake

to manage the risks in

response to anticipated changes

in interest rates or client

deposit behavior. As part of

our ALM strategy and policy,

management has the ability to modify the balance sheet to either

increase or

decrease asset

duration and

increase or

decrease liability

duration to

modify the

balance sheet

sensitivity to

interest rates.

According to our model, as of

end of 2023, the NIM will

remain fairly stable for static rate

scenarios (-400 basis points:

+400 basis points). For the

static forecast for year one,

the estimated NIM will increase

from 2.81% base case scenario

to

2.86% under a +400-basis

points scenario. Additionally,

utilizing an EVE approach,

we analyze the risk

to capital from the

effects

of various

interest rate

scenarios

through a

long-term discounted

cash flow

model. This

measures

the difference

between the economic

value of our

assets and the

economic value of

our liabilities, which is

a proxy for

our liquidation value.

According to

our balance

sheet composition,

and as

expected, our

model stipulates

that an

increase of

interest rates

will

have a negative impact on

the EVE. Results and analysis are

presented quarterly to the ALCO, and

strategies are reviewed

and refined.

Additionally, in the last year we have been reducing our asset sensitivity by extending asset duration. This has reduced

our NII volatility for the first and

second year in the analysis and has helped us

to maintain the NII in accordance with ALCO

expectations.

Liquidity

Liquidity is

defined as

a Company’s capacity

to meet

its cash

and collateral

obligations at

a reasonable

cost. Maintaining

an adequate level of liquidity depends on the Company’s ability to

efficiently meet both expected and unexpected cash flow

and collateral needs without adversely affecting

either daily operations or the financial condition of the

Company.

Liquidity risk

is the

risk that

we will

be unable

to meet

our short-term

and long-term

obligations as

they become

due

because of an

inability to liquidate

assets or obtain

adequate funding on

acceptable terms in

a timely matter. The

Company’s

obligations, and the funding sources used to meet them, depend significantly

on our business mix, balance sheet structure

and composition, credit quality of

our assets, interest rate

environment and the cash flow

profiles of our on- and

off-balance

sheet obligations.

In

managing

cash

inflows

and

outflows,

management

regularly

monitors

situations

that

can

give

rise

to

increased

liquidity risk.

These include

funding mismatches, market

constraints on

the ability

to convert

assets (particularly investments)

into cash or in

accessing sources of

funds (i.e., market

liquidity), and contingent

liquidity events. Management

presents to

the ALCO,

on a

quarterly basis, liquidity

stress tests following

the scenarios

described in

the Company’s contingency

funding

plan.

Changes

in

macroeconomic

conditions,

exposure

to

credit

deterioration,

market,

operational,

legal

and

reputational

risks, including cybersecurity risk and

social media events could

also affect the Company’s liquidity risk

profile unexpectedly

and are considered in the assessment of liquidity and ALM

framework.

Management has established

a comprehensive and

holistic management process for

identifying, measuring, monitoring

and

mitigating

liquidity

risk.

Due

to

its

critical

importance

to

the

viability

of

the

Company,

liquidity

risk

management

is

integrated into our risk management processes, Contingency

Funding Plan and ALM policy.

Critical elements of our liquidity

risk management include: effective corporate governance consisting of

oversight by the

Board and ALCO and

involvement by senior management;

strategies, policies, procedures,

and limits used to

identify and

mitigate

liquidity

risk;

comprehensive

liquidity

risk

measurement

and

monitoring

systems

(including

assessments

of

the

current and prospective cash flows or sources and uses of funds) that are commensurate with the complexity and

business

activities

of the

Company;

management

of intraday

liquidity and

collateral;

a diverse

mix of

existing

and

potential

future

funding sources; adequate levels of highly liquid marketable securities free

of legal, regulatory, or operational impediments,

that can

be used

to meet

liquidity needs

in stressful situations;

comprehensive contingency

funding plans

that sufficiently

address potential adverse

liquidity events and

emergency cash

flow requirements; and

internal controls and

internal audit

processes sufficient to determine the adequacy

of the institution’s liquidity risk management

process.

We

expect

funds

to

be

available

from

several

basic

banking

activity

sources,

including

the

core

deposit

base,

the

repayment and maturity of loans and investment security

cash flows. Other potential funding sources include

federal funds

purchased, brokered

certificates

of deposit,

listing certificates

of deposit,

Fed funds

lines and

borrowings from

the FHLB

Atlanta. Accordingly, our liquidity resources were at sufficient levels to

fund loans and meet other

cash needs as necessary.

At December 31, 2023,

the Company had $224.8

million in available liquidity

on balance sheet, including

$187.7 million in

unpledged securities available to

use as collateral and

$37.1 million in

excess cash. The Company

had an additional $395.0

million in off balance sheet liquidity,

excluding access to brokered deposits and other off balance

sheet sources of funding.

Impact of Inflation

Our Consolidated

Financial Statements

and related

notes have been

prepared in

accordance with U.S.

GAAP,

which

requires the

measurement of

financial position

and operating

results in

terms of

historical dollars,

without considering

the

changes

in

the

relative

purchasing

power

of

money

over

time due

to

inflation.

The

impact

of

inflation

is

reflected

in

the

increased cost of operations.

Unlike most industrial companies,

nearly all our assets and

liabilities are monetary in

nature.

As a result,

interest rates have a

greater impact on our

performance than do the

effects of general levels

of inflation. Periods

of high inflation

are often accompanied

by relatively higher

interest rates, and

periods of low

inflation are accompanied

by

relatively lower interest rates.

As market interest rates

rise or fall in relation

to the rates earned

on loans and investments,

the value of these assets decreases or increases respectively.

REPORT OF INDEPENDENT REGISTERED

PUBLIC ACCOUNTING FIRM

Stockholders and the Board of Directors of

USCB Financial Holdings, Inc.

Doral, Florida

Opinion on the Financial Statements

We

have

audited

the

accompanying

consolidated

balance sheets

of USCB

Financial

Holdings,

Inc. (the

"Company")

as

of

December

31,

2023

and

2022,

the

related

consolidated

statements

of

operations,

comprehensive income

(loss), changes

in stockholders’

equity,

and cash

flows for

the years

then ended,

and the

related

notes

(collectively

referred

to as

the

"financial statements").

In

our opinion,

the

financial

statements present fairly, in all material respects, the

financial position of the Company

as of December 31,

2023 and 2022, and the results

of its operations and its cash

flows for the years then ended, in conformity

with accounting principles generally accepted in the United

States of America.

Explanatory Paragraph - Change in Accounting Principle

As discussed in Note 1 to the financial

statements, the Company has changed its method of accounting for

credit losses effective January 1, 2023 due to the adoption

of ASU 2016-13 Financial Instruments – Credit

Losses

(ASC

Topic

326).

The

Company

adopted

the

new

credit

loss

standard

using

the

modified

retrospective

method

such

that

prior

period

amounts

are

not

adjusted

and

continue

to

be

reported

in

accordance with previously applicable generally accepted accounting

principles.

Basis for Opinion

These financial

statements are

the responsibility

of the

Company's management.

Our responsibility

is to

express an opinion

on the Company's financial

statements based on our

audits. We are a

public accounting

firm registered

with the

Public Company

Accounting Oversight

Board (United

States) ("PCAOB")

and are

required to be

independent with respect to

the Company in accordance

with the U.S.

federal securities laws

and the applicable rules and regulations of the Securities

and Exchange Commission and the PCAOB.

We conducted

our audits

in accordance

with the

standards of

the PCAOB.

Those standards

require that

we plan and perform the

audit to obtain reasonable

assurance about whether the

financial statements are

free of material misstatement, whether due to error or fraud.

Our

audits

included

performing

procedures

to

assess

the

risks

of

material

misstatement

of

the

financial

statements, whether

due to

error or

fraud, and

performing procedures

that respond

to those

risks.

Such

procedures

included examining,

on a

test basis,

evidence

regarding the

amounts

and disclosures

in the

financial

statements.

Our

audits

also

included

evaluating

the

accounting

principles

used

and

significant

estimates made by management, as well as evaluating the

overall presentation of the financial statements.

We believe that our audits provide a reasonable

basis for our opinion.

SUMMARY OF SIGNIFICANT ACCOUNTING

POLICIES

Overview

USCB Financial Holdings, Inc., a

Florida corporation incorporated

in 2021, is a bank holding

company with one wholly

owned subsidiary,

U.S. Century Bank (the

“Bank”), together referred to

as “the Company”. The

Bank, established in 2002,

is a Florida

state-chartered, non-member financial institution providing financial

services through its banking

centers located

in South Florida.

In December 2021, USCB Financial

Holdings, Inc. acquired all issued

and outstanding shares of the Class

A common

stock of

the Bank

in connection

with the

reorganization of the

Bank into

a holding

company structure. Each

of the

outstanding

share of

the Bank’s

common stock,

par value

$

1.00

per share,

formerly held

by its

stockholders were

converted into

and

exchanged for one newly issued share of the Company’s

Class A common stock, par value $

1.00

per share.

The Bank

owns a

subsidiary,

Florida Peninsula

Title LLC,

that offers

our clients

title insurance

policies for

real estate

transactions closed at the Bank. Licensed in the State of Florida and approved by the Department of Insurance Regulation,

Florida Peninsula tittle LLC began operations in 2021.

Principles of Consolidation

Intercompany transactions

and balances

are eliminated

in consolidation.

The consolidated

financial statements

have

been prepared in accordance with GAAP.

Risk and Uncertainties

Banking Environment

Industry events

transpiring early

in 2023,

including bank

failures, have

led to

uncertainty and

concerns regarding

the

liquidity positions

of the

banking sector.

The Company’s

deposit base

includes

a combination

of consumer,

commercial,

and public

funds deposits.

The Company’s

largest depositors

include a

mixture of

government-related

organizations and

commercial clients without a high level of industry concentration.

In response

to these

events, the

Treasury

Department, the

Board of

Governors

of the

Federal Reserve

System, and

the FDIC

jointly announced

the Bank

Term

Funding Program

(BTFP) on

March 12,

  1. This

program aims

to enhance

liquidity by allowing institutions to pledge

certain securities at the par value

of the securities, and at a

borrowing rate of ten

basis

points

over

the

one-year

overnight

index

swap

rate.

The

BTFP

was

available

to

eligible

U.S.

federally

insured

depository institutions, with

advances having a

term of up to

one year and

no prepayment penalties.

In January 2024,

the

Company drew

$

80.0

million in the

BTFP; there

were

no

draws in 2023.

No further draws

were permitted

after March 11,

  1. All advances must be paid by January 2025.

Market conditions and external factors may unpredictably impact the competitive landscape for deposits in the banking

industry.

Additionally,

the

rising

interest

rate

environment

experienced

in

2022

and

2023

has

increased

competition

for

liquidity and the premium at

which liquidity is available to

meet funding needs. The Company

believes its sources of liquidity

are sufficient to meet its needs as of the balance sheet

date.

An unexpected influx

of withdrawals of

deposits could adversely

impact the Company's

ability to

rely on organic

deposits

to primarily

fund its

operations, potentially

requiring greater

reliance on

secondary sources

of liquidity

to meet

withdrawal

demands or to fund continuing operations. These sources may include proceeds from FHLB advances, sales of

investment

securities and loans, federal funds lines of credit from correspondent

banks, and out-of-market time deposits.

Such reliance on secondary funding sources could increase the Company's

overall cost of funding and thereby reduce

net

income.

While

the

Company

believes

its

current

sources

of

liquidity

are

adequate

to

fund

operations,

there

is

no

guarantee they

will suffice

to meet

future

liquidity

demands.

This

may necessitate

slowing

or discontinuing

loan growth,

capital expenditures, or other investments, or liquidating assets.

Use of Estimates

The

Company

has

established

policies

and

control

procedures

that

are

intended

to

ensure

valuation

methods

are

controlled and

applied consistently

from period

to period.

These estimates

and assumptions,

which may

materially affect

Table of Contents

Notes to the Consolidated Financial Statements

81

USCB Financial Holdings, Inc.

2023 10-K

the reported amounts of

certain assets, liabilities, revenues

and expenses, are based

on information available as

of the date

of the

financial statements,

and changes

in this

information over

time and

the use

of revised

estimates and

assumptions

could materially affect amounts reported in subsequent

financial statements.

Cash and Cash Equivalents

The

Company

considers

investments

with

a

maturity

of

90

days

or

less

from

its

original

purchase

date

to

be

cash

equivalents. For

the Consolidated

Statements of

Cash Flows,

cash and cash

equivalents include

cash on hand,

amounts

due from banks, and interest-bearing deposits in banks.

Restricted Cash

The Company may be required to maintain

funds at other banks to satisfy

the terms of a loan participation agreement.

The Company reports restricted cash

within cash and cash equivalents.

At the years ended December

31, 2023 and 2022

the company had $

0

in restricted cash.

Interest-Bearing Deposits in Other Financial Institutions

Interest-bearing deposits in other financial institutions consist

of Federal Reserve Bank, Federal Home Loan

Bank and

other accounts.

Investment Securities

Debt securities

are recorded

at fair

value except

for those

securities which

the Company

has the

positive intent

and

ability to hold to

maturity. Management determines the appropriate classification of its securities at

the time of purchase

and

accounts for them on a trade date basis.

Debt securities that

management has the

positive intent and

ability to hold

to maturity are

classified as "held-to-maturity"

and recorded at amortized cost. Trading securities are

recorded at fair value with

changes in fair value included

in earnings.

Securities not classified

as held-to-maturity or

trading are classified

as "available-for-sale"

and recorded at

fair value, with

unrealized gains and

losses excluded from

earnings and reported

in other comprehensive

income (loss). Equity

investments

must be recorded at fair value with changes in fair value

included in earnings.

Purchase premiums and discounts are amortized or accreted over

the estimated life of the related available-for-sale or

held-to-maturity

security

as

an

adjustment

to

yield

using

the

effective

interest

method.

Prepayments

of

principal

are

considered in determining the estimated life of

the security. Such amortization and accretion are included in interest income

in the Consolidated

Statements of Operations.

Dividend and interest

income are recognized

when earned. Gains

and losses

on the sale of securities are recorded on trade date and are determined

on a specific identification basis.

On

January

1,

2023,

the

Company

adopted

ASU

2016-13

Financial

Instruments

-

Credit

Losses

(Topic

326):

Measurement of Credit Losses

on Financial Instruments,

as amended, which replaces

the incurred loss methodology

with

an expected

loss methodology

that is

referred to as

the CECL

methodology.

The measurement

of expected

credit losses

under the CECL methodology

is applicable to financial

assets measured at amortized

cost, including loan receivables

and

held-to-maturity debt

securities. In

addition, ASC

326 amended

the accounting

for available-for-sale

debt securities.

One

such change is

to require credit

losses to be

presented as an

allowance rather than

as a write-down

on available-for-sale

debt securities management does not intend to sell or

believes that it is more likely than not they will be required

to sell.

CECL requires a loss reserve for securities

classified as HTM. The reserve should reflect

historical credit performance

as well as the impact

of projected economic forecast.

For U.S. Government bonds

and U.S. Agency issued bonds

in HTM

the explicit and/or

implicit guarantee of the

US Government is sufficient to

conclude that a

credit loss reserve is

not required.

The

reserve

requirement

is

for

three

primary

assets

groups:

municipal

bonds,

corporate

bonds,

and

non-agency

securitizations.

The

Company

calculates

quarterly

the

loss

reserve

utilizing

Moody’s

ImpairmentStudio.

The

CECL

measurement

for

investment

securities

incorporates

historical

data,

containing

defaults

and

recoveries

information,

and

Moody’s baseline

economic forecast.

The solution

uses probability

of default/loss

given default (“PD/LGD”)

approach. PD

represents the likelihood a borrower will

default. Within the Moody’s model,

this is determined using historical

default data,

adjusted for the current economic environment. LGD projects

the expected loss if a borrower were to default.

Federal Home Loan Bank (FHLB) Stock

The Bank is a member of the FHLB system. Members are required to

own a certain amount of stock based on the level

of borrowings and

other factors and

may invest in

additional amounts. FHLB

stock is carried

at cost, classified

as a restricted

asset, and

periodically evaluated

for impairment

based on

ultimate recovery

of par

value. As

of December

31, 2023

and

2022, FHLB

stock amounted

to $

10.2

million and

$

2.9

million, respectively,

with no

impairment deemed

necessary.

Both

cash and stock dividends are reported as interest income.

Loans Held for Investment and Allowance for Credit

Losses

Loans held for investment (“loans”) are reported at their outstanding principal

balance net of charge-offs, deferred loan

cost,

unearned

income, and

the ACL.

Interest income

is generally

recognized

when

income is

earned using

the interest

method.

Loan

origination

and

commitment

fees

and

the

costs

associated

with

the

origination

of

loans

are

deferred

and

amortized, using the interest method or the straight-line

method, over the life of the related loan.

If the

principal or

interest on

a commercial

loan becomes

due and

unpaid for

90 days

or more,

the loan

is placed

on

non-accrual status as of

the date it becomes

90 days past due

and remains in non

-accrual status until it

meets the criteria

for restoration to accrual status.

Residential loans, on

the other hand, are placed

on non-accrual status when

the principal

or interest

becomes due

and unpaid

for 120

days or

more and remains

in non-accrual

status until

it meets

the criteria

for

restoration

to

accrual

status.

Restoring

a

loan

to

accrual

status

is

possible

when

the

borrower

resumes

payment

of

all

principal and interest

payments for a period

of six months

and the Company

has a documented

expectation of repayment

of the remaining contractual principal and interest or the loan becomes secured and in the process of collection. All interest

accrued but not

collected for

loans that are

placed on

nonaccrual status

is reversed

against interest

income. The interest

on these

loans is

accounted for

on the

cash-basis

or cost-recovery

method, under

which cash

collections are

applied to

unpaid principal, which may change as conditions dictate.

The Company has determined that the entire balance of

a loan is contractually delinquent for all

classes if the minimum

payment is not received by

the specified due date on

the borrower's statement. Interest and fees

continue to accrue on past

due loans until the date the loan goes into nonaccrual

status.

The Company provides for loan losses through a provision for credit losses charged to operations. When management

believes that a

loan or a portion

of the loan balance

is uncollectible, that

amount is charged

against the ACL.

Subsequent

recoveries, if any,

are credited to the ACL.

The

ACL

reflects

management's

judgment

of

expected

loan

losses

in

the

portfolio

at

the

balance

sheet

date.

Management uses a disciplined

process and methodology

to establish the ACL

each quarter.

To

determine the total

ACL,

the Company

estimates the

reserves needed

for each

segment of

the portfolio,

including loans

analyzed individually

and

loans analyzed on a pooled basis. The ACL consists

of the amount applicable to the following segments:

Residential real estate

Commercial real estate

Commercial and industrial

Foreign banks

Other loans (secured and unsecured consumer loans)

Residential

real

estate

loans

are

underwritten

following

the

policies

of

the

Company

which

include

a

review

of

the

borrower’s credit, capacity

and the collateral

securing the loan.

The borrower’s ability

to repay involves

an analysis of

factors

including: current income,

employment status, monthly

payment of

the loan,

current debt

obligations, monthly debt

to income

ratio and credit history. The Company relies on appraisals in determining the value of the property.

Risk is mitigated by this

analysis and the diversity of the residential portfolio.

Commercial real estate

loans are

secured by liens

on commercial properties,

land, construction and

multifamily housing.

Underwriting of commercial real estate loans will analyze the key market and business factors to arrive at a decision on the

credit worthiness of the borrower. The analysis may include the capacity of the borrower,

income generated by property for

debt service,

other

sources

of repayment,

sensitivity

analysis

to fluctuations

in market

conditions

including vacancy

and

rental rates in geographic

location and loan

to value. Land

and construction loan

analysis will include

the time to

develop,

sell or lease

the property.

Appraisals are used

to determine the

value of the

underlying collateral.

Risk is mitigated

as the

properties securing the commercial real estate loans

are diverse in type, location, and loan structure.

Commercial

and

industrial

loans

are

secured

by

the

business

assets

of

the

company

and

may

include

equipment,

inventory, and receivables.

The loans are underwritten based on the

income capacity of the business, the ability

to service

the debt based

on operating cash

flows, the credit

worthiness of the

borrower,

other sources

of repayment and

collateral.

The Company mitigates the risk in the commercial portfolio

through industry diversification.

Foreign banks

loans

are short

-term

loans with

international

correspondent

banking

institutions

primarily

domiciled

in

Latin America. Most of these loans are for trade capital and have a

life of less than one year. The Company’s

credit review

includes a credit analysis, peer comparison and current

country risk overview.

Annual re-evaluation of the risk rating of the

borrower and country where the borrower is

located and a review by the authorized signer

within the Company.

The risk is

mitigated as these loans are short term, have limited exposure,

and are geographically dispersed.

Other loans are secured and

unsecured consumer loans including

yacht loans, personal loans, overdrafts

and deposit

account collateralized loans. Repayment of these loans are primarily from the personal income of the borrowers. Loans are

underwritten based on the credit worthiness of the borrower.

The risk on these loans is mitigated by small loan balances.

Under

CECL,

the

Company

estimates

the

ACL

using

relevant

available

information,

from

both

internal

and

external

sources,

relating

to

past

events,

current

conditions,

and

reasonable

and

supportable

forecasts.

Historical

credit

losses

provide the basis for estimation of expected credit losses. Qualitative adjustments are applied to the expected credit losses

estimated

for

the

loan

portfolio

in

relation

to

potential

limitations

of

the

quantitative

model.

A

scorecard

is

used

to

aid

management in the assessment of qualitative factor adjustments

applied to expected credit losses.

The

quantitative

component

of

the

estimate

relies

on

the

statistical

relationship

between

the

projected

value

of

an

economic

indicator

and

the

implied

historical

loss

experience

among

a

curated

group

of

peers.

The

Company

utilized

regression

analyses

of peer

data,

in

which

is

assigned

to

each

pool

for

each

period

based

on

these

PD

outcomes.

The

model

fundamentally utilizes

an expected

discounted cash

flow (DCF)

analysis for loan

portfolio segments.

The DCF

analysis is

run

at

the

instrument-level

and

incorporates

an

array

of

loan-specific

data

points

and

segment-implied

assumptions

to

determine the lifetime expected

loss attributable to each

instrument. An implicit "hypothetical

loss" is derived

for each period

of the

DCF and

helps establish

the present

value of

future cash

flows for

each period.

The reserve

applied to

a specific

instrument is the difference

between the sum of the present

value of future cash flows

and the book balance of

the loan at

the measurement date.

Management

elected

the

Remaining

Life

(WARM)

methodology

for

five

loan

portfolio

segments.

For

each

of

these

segments, a

long-term average

loss rate

is calculated

and applied

on a

quarterly basis

for the

remaining life

of the

pool.

Adjustments

for

economic

expectations

are

made

through

qualitative

assessments.

For

the

remaining

life

estimated,

management implemented a software

solution that uses an

attrition-based calculation that performs quarterly, cohort-based

attrition measurements based on the loan portfolio.

Portfolio segments are the level at which loss assumptions

are applied to a pool of loans based on the similarity

of risk

characteristics inherent in the

included instruments, relying on

collateral codes and FFIEC

Call Report codes. The

Company

currently segments the

portfolio based on

collateral codes for

the

purpose of establishing

reserves. Each of

these segments

is

paired

to

regression

models

(Loss

Driver

Analyses)

based

on

peer

data

for

loans

of

similar

risk

characteristics.

The

Company has established relationships between internal segmentation and FFIEC

Call Report codes for this purpose. The

loss driver for each loan

portfolio segment is derived

from a readily available and

reasonable economic forecast, including

the Federal Reserve Bank

projections of U.S. civilian

unemployment rate and the

year-over-year real GDP

growth; for the

residential

loan

segment

the

HPI

projections

published

by

Fannie

Mae’s

Economic

and

Strategic

Research

Group

are

utilized for the

forecast. Forecasts

are applied to

the first four

quarters of the

credit loss estimate

and revert on

a straight-

line basis to the lookback period's historical mean for the

economic indicator over the expected life of loans.

The model incorporates qualitative

factor adjustments in order to

calibrate the model for risk

in each portfolio segment

that may

not be captured

through quantitative

analysis. Determinations

regarding qualitative

adjustments are

reflective of

management's

expectation

of loss

conditions

differing

from those

already

captured

in

the

quantitative

component

of

the

model.

Qualitative factors (“Q-Factors”) used in the ACL methodology

include:

• Changes in lending policies, procedures, and strategies

• Changes in international, national, regional, and local conditions

• Changes in nature and volume of portfolio

• Changes in the volume and severity of past due loans

and other similar conditions

• Concentration risk

• Changes in the value of underlying collateral

• The effect of other external factors: e.g., competition,

legal, and regulatory requirements

• Changes in lending management, among others

The

Company

estimates

a

reserve

for

unfunded

commitments,

which

is

reported

separately

from

the

allowance

for

credit losses within

other liabilities. The

reserve is based

upon the same

quantitative and qualitative

factors applied to

the

collectively evaluated loan portfolio.

Concentration of Credit Risks

Credit

risk

represents

the

accounting

loss

that

would

be

recognized

at

the

reporting

date

if

counterparties

failed

to

perform as contracted and any collateral or security proved to be insufficient

to cover the loss. Concentrations of credit risk

(whether on or off-balance sheet) arising from financial instruments exist in relation to certain

groups of customers. A group

concentration arises

when a number

of counterparties

have similar economic

characteristics that would

cause their ability

to meet contractual obligations to be similarly affected by changes in economic or other conditions. The Company does not

have a significant exposure to any individual customer

or counterparty.

Most of the Company's business activity is

with customers located within its primary market area, which

is generally the

State of Florida. The Company's loan portfolio is concentrated largely in real estate and commercial loans in South Florida.

Many of the

Company's loan

customers are engaged

in real estate

development. Circumstances

which negatively

impact

the South Florida real estate industry

or the South Florida economy, in general, could adversely impact

the Company's loan

portfolio.

At December 31,

2023 and

2022, the

Company had

a concentration

of risk

with loans

outstanding to

the Company’s

top ten lending relationships

totaling $

163.1

million and $

197.9

million, respectively.

At December 31, 2023 and

2022, this

concentration represented

9.2

% and

13.1

% of

net loans

outstanding, respectively.

For the

periods ended

December 31,

2023 and December 31, 2022, the largest commercial real estate loan note

outside Florida was

one

commercial real estate

loan with an outstanding balance of $

20

million collateralized by a 1

st

lien commercial property located in New York

State.

At December 31, 2023,

the Company had

a concentration of

risk with loans

outstanding totaling $

105.4

million to foreign

banks located in Ecuador, Dominican Republic, Honduras, and El Salvador. At December 31, 2022, the Company also had

a concentration of risk

with loans outstanding totaling

$

88.8

million to foreign banks

located in Ecuador,

Honduras, and El

Salvador.

These

banks

maintained

deposits

with

right

of

offset

totaling

$

43.9

million

and

$

31.4

million

at

December 31,

2023 and 2022, respectively.

At various times during

the year,

the Company has maintained

deposits with other

financial institutions. The exposure

to the Company from

these transactions is solely

dependent upon daily balances

and the financial strength

of the respective

institution.

Premises and Equipment, net

Land is

carried at

cost. Premises

and equipment

are stated

at cost

less accumulated

depreciation

and amortization.

Depreciation is computed

on the straight-line

method over the

estimated useful life

of the asset. Leasehold

improvements

are amortized over the

remaining term of the

applicable leases or their

useful lives, whichever

is shorter.

Estimated useful

lives of these assets were as follows:

Building

s

40

years

Furniture, fixtures and equipment

3

to

25

years

Computer hardware and software

3

to

5

years

Leasehold improvements

Shorter of life or term of lease

Maintenance

and

repairs

are

charged

to

expense

as

incurred

while

improvements

and

betterments

are

capitalized.

When items are retired or are

otherwise disposed of, the related costs

and accumulated depreciation and amortization

are

removed from the accounts and any resulting gains or losses

are credited or charged to income.

Other Real Estate Owned

OREO consists of real estate

property acquired through, or

in lieu of, foreclosure that

are held for sale and are

initially

recorded at

the fair

value of

the property

less estimated

selling costs

at the

date

of foreclosure,

establishing

a new

cost

basis. Subsequent to

foreclosure, valuations

are periodically performed

by management and

the assets are

carried at the

lower of carrying

amount or

fair value

less cost

to sell.

Subsequent write-downs

are recognized

as a

valuation allowance

with

the

offset

recorded

in

the

Consolidated

Statements

of

Operations.

Carrying

costs

are

charged

to

other

real

estate

owned

expenses

in

the

accompanying

Consolidated

Statements

of

Operation.

Gains

or

losses

on

sale

of

OREO

are

recognized when

consideration has

been exchanged,

all closing

conditions have

been met

and permanent

financing has

been arranged.

Bank Owned Life Insurance

BOLI is carried at

the amount that could

be realized under the

contract at the balance sheet

date, which is typically

cash

surrender

value.

Changes

in

cash

surrender

value

are

recorded

in

non-interest

income.

At

December 31,

2023,

the

Company

maintained

BOLI

policies

with

five

insurance

carriers

with

a

combined

cash

surrender

value

of

$

51.8

million.

These policies cover certain present and former executives

and officers, the Company is the beneficiary

of these policies.

Employee 401(k) Plan

The

Company

has

an

employee

401(k)

plan

covering

substantially

all

eligible

employees.

Employee

401(k)

plan

expense is the amount of matching contributions.

Income Taxes

Income taxes are accounted for under the

asset and liability method. Deferred tax

assets and liabilities are recognized

for the

future

tax

consequences

attributable

to differences

between the

financial

statement

carrying

amounts

of existing

assets and

liabilities and

their respective

tax bases

and operating

loss and

tax credit

carryforwards. Deferred

tax assets

and

liabilities

are

measured

using

enacted

tax

rates

expected

to

apply

to

taxable

income

in

the

years

in

which

those

temporary differences are expected to be recovered

or settled. The effect on deferred tax assets and

liabilities of a change

in tax rates is recognized in income in the period that includes

the enactment date.

Management is required to

assess whether a valuation

allowance should be established

on the net deferred tax

asset

based on the

consideration of

all available evidence

using a more

likely than not

standard. In its

evaluation, Management

considers taxable loss

carry-back availability, expectation of sufficient

taxable income, trends

in earnings, the

future reversal

of temporary differences, and available tax planning

strategies.

The Company recognizes positions taken

or expected to be

taken in a tax

return in accordance with existing accounting

guidance on

income taxes

which prescribes

a recognition threshold

and measurement

process. Interest

and penalties

on

tax liabilities, if any, would

be recorded in interest expense and other operating noninterest

expense, respectively.

Impairment of Long-Lived Assets

The Company's long-lived

assets, such as premises

and equipment, are reviewed

for impairment whenever

events or

changes in circumstances

indicate that

the carrying

amount of

an asset may

not be recoverable.

Recoverability of

assets

to be held and

used is measured by a

comparison of the carrying amount of

an asset to estimated undiscounted future

cash

flows expected to be generated by the asset. If the carrying amount of an asset exceeds its estimated future cash flows, an

impairment charge

is recognized

by the

amount by

which the

carrying amount

of the

asset exceeds

the fair

value of

the

asset. Assets

to be

disposed of

would be

separately

presented in

the Consolidated

Balance Sheets

and reported

at the

lower of

the carrying

amount or

fair value

less costs

to sell

and are

no longer

depreciated. The

assets and

liabilities of

a

disposal group classified as held for

sale would be presented separately in

the appropriate asset and liability sections of

the

Consolidated Balance Sheets.

Transfer of Financial Assets

Transfers of

financial assets

are accounted for

as sales,

when control over

the assets

has been surrendered.

Control

over

transferred

assets

is

deemed

to

be

surrendered

when

(i)

the

assets

have

been

isolated

from

the

Company

-

put

presumptively

beyond

the

reach

of

the

transferor

and

its

creditors,

even

in

bankruptcy

or

other

receivership,

(ii)

the

transferee obtains

the right

(free of conditions

that constrain

it from taking

advantage of

that right)

to pledge

or exchange

the transferred

assets,

and

(iii) the

Company

does not

maintain effective

control

over

the transferred

assets

through

an

agreement to repurchase them before their maturity or

the ability to unilaterally cause the holder to return specific assets.

Comprehensive Income (Loss)

Under

GAAP,

certain

changes

in

assets

and

liabilities,

such

as

unrealized

holding

gains

and

losses

on

securities

available-for-sale, are

excluded from

current period

earnings and

reported as

a separate

component of

the stockholders’

equity section of the Consolidated

Balance Sheets, such items,

along with net income, are

components of comprehensive

income (loss).

Additionally,

any unrealized

gains or

losses on

transfers of

investment securities

from available-for-sale

to

held-to-maturity are recorded to

accumulated other comprehensive income (loss)

on the date

of transfer and amortized

over

the remaining life of each security. The amortization

of the unrealized gain or loss on transferred securities is reported as a

component of comprehensive income (loss). See Note 2 “Investment

Securities” for further discussion.

Advertising Costs

Advertising costs are expensed as incurred.

Earnings per Common Share

Basic earnings

per common

share is

net income

available to

common stockholders

divided by

the weighted

average

number

of

common

shares

outstanding

during

the

period.

Diluted

earnings

per

common

share

included

the

effect

of

additional potential

common shares

issuable under

vested stock

options and

unvested restricted

stock. Basic

and diluted

earnings

per

share

are

updated

to

reflect

the

effect

of

stock

splits

as

occurred.

See

Note

14

“Earnings

Per

Share”

for

additional information

on earnings

per common

share. See

Note 13

“Stockholders’ Equity”

for further discussion

on stock

splits.

Interest Income

Interest income is recognized as earned, based upon the principal

amount outstanding, on an accrual basis.

Operating Segments

While the Company monitors

the revenue streams of

the various products

and services, operations

are managed and

financial performance

is evaluated on

a Company wide

basis. Operating results

of the individual

products are

not used to

make resource allocations or performance decisions by Company

management.

Stock-Based Compensation

Stock-based compensation accounting guidance requires that the compensation

cost relating to share-based payment

transactions be recognized in the accompanying Consolidated

Financial Statements. That cost will be measured

based on

the grant

date fair

value of

the equity

or liability

instruments issued.

The stock-based

compensation accounting

guidance

covers

a

wide

range

of

share-based

compensation

arrangements

including

stock

options,

restricted

share

awards,

performance-based awards, share appreciation rights, and

employee share purchase plans.

The stock-based compensation accounting guidance

requires that compensation cost

for all stock

awards be calculated

and recognized

over the

employees' service period,

generally defined as

the vesting

period. For

awards with graded-vesting,

compensation cost

is recognized

on

a straight-line

basis over

the

requisite service

period for

the

entire award.

A Black-

Scholes model is used to estimate the fair value of stock

options.

Loss Contingencies

Loss

contingencies,

including

claims

and

legal

actions

arising

in

the

normal

course

of

business,

are

recorded

as

liabilities when the

likelihood of loss is

probable, and an

amount or range of

loss can be

reasonably estimated. In the

opinion

of management, none of these actions, either individually or in the aggregate, is expected to have a material adverse effect

on the Company’s Consolidated Financial Statements.

See Note 18 “Loss Contingencies” for further details.

levels

and

may

limit

Company or by the Company to the stockholders.

Fair Value Measurements

Fair values

of financial

instruments are

estimated using

relevant market

information and

other assumptions,

as more

fully disclosed in Note

12 “Fair Value

Measurements”. Fair value estimates

involve uncertainties and

matters of significant

judgment. Changes in assumptions or in market conditions

could significantly affect the estimates.

Derivative Instruments

Derivative financial instruments are

carried at fair

value and reflect

the estimated amount that

would have been

received

to

terminate

these

contracts

at

the

reporting

date

based

upon

pricing

or

valuation

models

applied

to

current

market

information.

Rate Swaps Designated as Cash Flow Hedges

The

changes

in

fair

value

on

these

interest

rate

swaps

are

recorded

in

other

assets

or

other

liabilities

with

a

corresponding recognition

in other comprehensive

income (loss)

and subsequently reclassified

to earnings when

gains or

losses are realized. As of December 31, 2023 the cash

flow hedge was effective.

Interest Rate Swaps Designated as Fair Value

Hedges

The

changes

in

fair

value

on

these

interest

rate

swaps

are

recorded

in

other

assets

or

other

liabilities

with

a

corresponding recognition in the assets being hedged.

Interest Rate Swaps

The Company enters into interest rate swaps

agreements to provide commercial loan clients

the ability to swap from a

variable interest rate to a fixed rate. The Company

enters into a floating-rate loan with a customer with

a separately issued

swap agreement allowing

the customer to convert

floating payments on

the loan into a

fixed interest rate. To

mitigate risk,

the Company enters into a matching agreement with

a third party to offset the exposure on

the customer agreement. These

swaps are

not considered

to be

qualified hedging

transactions and

the unmatched

unrealized gain

or loss

is recorded

in

other non-interest income.

Interest

rate

swap

agreements

are

used

by

the

Company

as

part

of

its

asset-liability

management

strategy

to

help

manage its interest

rate risk exposure.

The notional amount

of the interest

rate swaps does

not represent actual

amounts

exchanged by the parties.

The amounts exchanged are determined

by reference to the

notional amount and the

other terms

of the individual interest rate swap agreements.

Revenue from Contracts with Customers

Revenue from

contracts with customers

is recognized in

an amount that

reflects the consideration

the Company expects

to receive for the

services the Company

provides to its

customers. The main

revenue earned by

the Company from

loans

and investment

securities

are excluded

from the

accounting standard

update “Revenue

from Contracts

with Customers”.

Deposit and

service charge

fees, consisting

of primarily

monthly maintenance

fees, wire

fees, ATM

interchange fees

and

other transaction-based fees, are the most

significant types of revenue within

the accounting standard update.

Revenue is

recognized when the service provided by the

Company is complete. The aggregate amount

of revenue within the scope of

this standard that is received from sources other than deposit

service charges and fees is not material.

Cash Flow Statement

The Company reports the net activity rather than gross activity in the Consolidated

Statements of Cash Flows. The net

cash

flows

are

reported

for

loans

held

for

investment,

accrued

interest

receivable,

deferred

tax

assets,

other

assets,

customer deposits, accrued interest payable, other liabilities, and

proceeds from the issuance of Class A common shares.

Recently Issued Accounting Standards

Issued and Adopted

Guidance on Accounting for Credit Losses on Financial Instruments

On January 1, 2023, the Company implemented Accounting Standard Update (“ASU”)

2016-13

Financial Instruments -

Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments, as amended. This update replaces the

incurred

loss

methodology

with

the

CECL

methodology.

The

CECL

methodology

measures

expected

credit

losses

and

applies to

financial assets

measured at

amortized cost,

including loan

receivables and

held-to-maturity debt

securities. It

also applies to off-balance sheet credit

exposures not accounted for as insurance

(e.g., loan commitments, standby letters

of

credit,

financial

guarantees,

and

similar

instruments),

as

well

as

net

investments

in

leases

recognized

by

lessors

in

accordance with Topic 842 on leases. Furthermore, ASC 326 amended the accounting treatment for available-for-sale debt

securities. One notable

change is

the requirement for

credit losses to

be reported

as an allowance

rather than as

a write-

down on available-for-sale debt securities that management does not intend to

sell or believes it is more likely than

not they

will not need

to sell. CECL

requires a

loss reserve

for securities

classified as

held-to-maturity (HTM).

The reserve

should

reflect historical credit performance as well as the impact

of projected economic

forecast.

At adoption

of CECL,

84

% or

$

1.3

billion of

loan receivables

were collectively

evaluated under

the Discounted

Cash

Flow (“DCF)” method

and

16

% or $

251.0

million of loan

receivables were collectively

evaluated under the

Remaining Life

method. The remaining $

7.9

million of loan receivables of the total loan portfolio

were individually evaluated.

The impact of

adoption of the

ASU 2016-13 in

January 1, 2023,

was an increase

to ACL on

loans receivables of

$

1.1

million and

an increase

to the

reserve for

unfunded commitments

of $

259

thousand. This

one-time net

of tax

cumulative

adjustment resulted in

a increase of

$

1.0

million in accumulated

deficit. The following

On

January

1,

2023,

the

Company

adopted

ASU

2016-13

Financial

Instruments

-

Credit

Losses

(Topic

326):

Measurement of Credit Losses

on Financial Instruments,

as amended, which replaces

the incurred loss methodology

with

an expected

loss methodology

that is

referred to

as CECL.

The measurement

of expected

credit losses

under the

CECL

methodology is applicable

to financial assets

measured at amortized

cost, including loan

receivables and

held-to-maturity

debt securities. In addition, ASC 326 amended the accou

nting for available-for-sale debt securities. One such

change is to

require

credit

losses

to

be

presented

as

an

allowance

rather

than

as

a

write-down

on

available-for-sale

debt

securities

management does not intend to sell or believes that

it is more likely than not they will be required to sell.

CECL requires a loss reserve for securities

classified as HTM. The reserve should reflect

historical credit performance

as well as the impact

of projected economic forecast.

For U.S. Government bonds

and U.S. Agency issued bonds

in HTM

the explicit guarantee of the US Government is sufficient

to conclude that a credit loss reserve is not required.

The reserve

requirement

is

for three

primary

assets

groups:

municipal

bonds,

corporate

bonds,

and

non-agency

securitizations.

The

Company calculates quarterly the loss reserve

utilizing Moody’s ImpairmentStudio. The CECL measurement for investment

securities

incorporates

historical

data,

containing

defaults

and

recoveries

information,

and

Moody’s

baseline

economic

forecast. The

solution uses

probability of

default/loss

given default

(“PD/LGD”)

approach. PD

represents the

likelihood a

borrower will

default.

Within the

Moody’s

model, this

is determined

using historical

default data,

adjusted for

the current

economic environment. LGD projects the expected loss

if a borrower were to default.

The Company monitors

the credit

quality of held

to maturity

securities through

the use of

credit ratings.

Credit ratings

are monitored by the Company on at least a quarterly basis. As of

December 31, 2023 and December 31, 2022, all held-to-

maturity securities held by the Company were rated investment

grade.

At December 31, 2023, HTM securities

included $

165.6

million of U.S. Government and

U.S. Agency issued bonds and

mortgage-backed

securities.

Because

of

the

explicit

and/or

implicit

guarantee

on

these

bonds,

the

Company

holds

no

reserves

on

these

holdings.

The

remaining

portion

of

the

HTM

portfolio

is

made

up

of

$

9.4

million

in

investment

grade

corporate bonds. The required reserve for these

holdings is determined each quarter using the model described above.

For

the portion of the HTM exposed to non-government

credit risk, the Company utilized the PD/LGD

methodology to estimate

a $

8

thousand ACL as

of December 31,

  1. The book

value for debt

securities classified as

HTM represents amortized

cost less ACL.

The

Company

determined

that

an

ACL

on

its

debt

securities

available

for

sale

as

of

December

31,

2023

was

not

required.

At

December

31,

2023,

the

Company

had

$

54.9

million

of

unrealized

losses

on

mortgage-backed

securities

and

collateralized mortgage

obligations of

U.S. Government

sponsored entities

having a

fair value

of $

284.1

million that

were

attributable

to

a

combination

of

factors,

including

relative

changes

in

interest

rates

since

the

time

of

purchase.

The

contractual cash flows for these securities are guaranteed by U.S. Government agencies

and U.S. Government sponsored

entities. The municipal bonds are of high credit

quality and the declines in fair value are

not due to credit quality.

Based on

the assessment of

these mitigating factors, management

believes that the

unrealized losses on these

debt security holdings

are a

function of

changes in

investment spreads

and interest

rate movements and

not changes

in credit

quality. Management

expects to recover the entire amortized cost basis of these securities.

At December 31, 2023, the

Company does not intend to

sell debt securities that are

in an unrealized loss position and

it is not more than likely than not that the Company will be required to sell

these securities before recovery of the amortized

cost basis.

As of December 31, 2023, the Company maintains a master repurchase agreement with a public banking institution for

up

to

$

20.0

million

fully

guaranteed

with

investment

securities

upon

withdrawal.

Any

amounts

borrowed

would

be

at

a

variable interest rate

based on prevailing

rates at the

time funding is

requested. At

December 31, 2023, the

Company did

no

t have any securities pledged under this agreement.

In 2018, the Company became a Qualified Public Depositor (“QPD”) with the State of Florida. As a QPD, the Company

has the

authority to

legally maintain public

deposits from cities,

municipalities, and the

State of

Florida. These public

deposits

are secured by

securities pledged to

the State of

Florida at a

ratio of

25

% of the

average outstanding uninsured

deposits.

The Company must also maintain a minimum amount

of pledged securities to be in the program.

At December 31, 2023, the Company had

twenty-eight

securities with a fair value of $

86.9

million pledged to the State

of Florida

under

the

public

funds

program.

The

Company

held

a total

of

$

268.4

in

public

funds

at

December 31,

The Board

of Governors

of the Federal

institutions

pledging

U.S.

Treasuries,

U.S.

At December 31, 2023 and 2022, the Company had $

534.2

million and $

338.1

million, respectively, of commercial real

estate and residential mortgage loans pledged as collateral on lines of credit with the FHLB and the

Federal Reserve Bank

of Atlanta. At December 31, 2023 and 2022, the Company

had

no

loans in the process of foreclosure.

The Company was a participant of the SBAs Paycheck

Protection Program (“PPP”) loans. These loans were

designed

to provide a direct incentive for small businesses

to keep their workers on payroll and

had to be used towards payroll cost,

mortgage interest, rent,

utilities and other

costs related to

COVID-19. These loans

are forgivable under

specific criteria as

determined by

the SBA.

The Company

had PPP

loans totaling

$

271

thousand at

December 31, 2023

and $

1.3

million at

December 31, 2022, which are categorized as commercial and industrial loans. These PPP

loans had deferred loan fees of

$

6

thousand at December 31, 2023 and $

13

thousand at December 31, 2022.

The

Company

recognized

$

Allowance for Credit Losses

In general, the Company utilizes

the Discounted Cash Flow (DCF)

method or the Remaining Life

(WARM) methodology

to estimate

the quantitative

portion of the

ACL for

loan pools.

The DCF

uses a

loss driver

analysis (LDA)

and discounted

cash flow analyses.

The Company engaged

advisors and consultants

with experience in

CECL model development

to assist

in development of

a loss driver

analysis based on

regression models

and supportable

forecast. Peer group

data obtained

from FFIEC Call Report

filings is used to

inform regression analyses

to quantify the impact

of reasonable and

supportable

forecasts in projective

models. Economic forecasts

receivables use at least

one of the following economic

indicators: civilian unemployment rate (national), real

gross domestic

product growth

(national

GDP) and/or

the HPI.

For each

of the

segments in

which the

WARM

methodology

is used,

the

long-term average loss rate is calculated and applied on a quarterly basis for the remaining life of the pool. Adjustments for

economic expectations are made through qualitative factors.

Qualitative factors (“Q-Factors”) used in the ACL methodology

include:

• Changes in lending policies, procedures, and strategies

• Changes in international, national, regional, and local conditions

• Changes in nature and volume of portfolio

• Changes in the volume and severity of past due loans

and other similar conditions

• Concentration risk

• Changes in the value of underlying collateral

• The effect of other external factors: e.g., competition,

legal, and regulatory requirements

• Changes in lending management, among others

The

Company

segments

the

portfolio

by

pools

grouping

loans

that

share

similar

risk

characteristics

and

employing

collateral type and lien position to group loans according to risk. The Company evaluates

five segments using the loss rate

methodology 'Remaining

Life Method'

or WARM.

The remaining

is calculated

based on

the annual

attrition rate

observed

for the Company’s own

portfolio experience. The

peer group includes historical

losses for U.S. The

Company also applies

a scorecard methodology

to determine

qualitative factors

for WARM

segments. The

scorecard is

built using

a peer group

loss. The maximum losses for

these peers are derived selecting

periods were higher than normal

loss rates are observed.

In estimating

credit losses,

the Company

also considers

qualitative and

environmental factors

that may

cause estimated

credit losses for the loan portfolio to differ from

historical losses.

ACL

for the

year

ended

December

31,

2023,

was

estimated

under

the

CECL

methodology,

and

for

the

year

ended

December 31, 2022, it was estimated under the incurred

loss model.

Prior to

the adoption

of ASC

326 on

January

1, 2023,

the allowance

for credit

losses

was a

valuation allowance

for

probable incurred credit

losses.

Management estimated the

allowance balance required

using past loan

loss experience,

the

nature

and

volume

of

the

portfolio,

information

about

specific

borrower

situations

and

estimated

collateral

values,

economic

conditions,

and

other

factors.

The

allowance

consisted

of

specific

and

general

components.

The

specific

component

related

to

loans

that

were

individually

classified

as

impaired.

A

loan

was

impaired

when,

based

on

current

information and events,

it was probable

that the Bank

would be

unable to

collect all

amounts due

according to

the contractual

Credit Quality Indicators

The Company grades loans based on the estimated capability of the borrower to repay the contractual obligation of the

loan agreement based

on relevant information

which may include:

current financial information

on the borrower,

historical

payment

experience,

credit

documentation

and

other

current

economic

trends.

Internal

credit

risk

grades

are

evaluated

periodically.

Table of Contents

USCB FINANCIAL HOLDINGS, INC.

Notes to the Consolidated Financial Statements

96

USCB Financial Holdings, Inc.

2023 10-K

The Company's internally assigned credit risk grades are as follows:

Pass

– Loans indicate different levels of satisfactory

financial condition and performance.

Special Mention

– Loans classified as special mention have a potential weakness

that deserves management’s

close attention. If left uncorrected, these potential weaknesses

may result in deterioration of the repayment

prospects for the loan or of the institution’s

credit position at some future date.

Substandard

– Loans classified as substandard are inadequately protected

by the current net worth and paying

capacity of the obligator or of the collateral pledged, if

any. Loans so classified

have a well-defined weakness or

weaknesses that jeopardize the liquidation of the debt.

They are characterized by the distinct possibility that the

institution will sustain some loss if the deficiencies are

not corrected.

Doubtful

– Loans classified as doubtful have all the weaknesses inherent

in those classified at substandard, with

the added characteristic that the weaknesses make collection

or liquidation in full on the basis of currently existing

facts, conditions, and values, highly questionable and improbable.

Loss

– Loans classified as loss are considered uncollectible.

arising

The

Company

elected the short-term

lease recognition exemption

for all leases

that qualify,

meaning those with

terms under 12

months.

ROU assets or lease liabilities are not to be recognized

for short-term leases.

ROU assets and

lease liabilities are

recognized at the lease

commencement date based on

the estimated present value

of lease payments

over the

lease term.

In the Company’s

Consolidated Balance

Sheets, ROU

assets are

reported under

other assets while lease liabilities are classified under

accrued interest and other liabilities.

As

most

of

Company’s

leases

the

rate

based

expiring in

various amounts

from 2032

to 2036

if unused

after 2036,

their utilization

is limited to

future

taxable earnings of the Company.

In assessing the

realizability of deferred

tax assets, management considered

whether it is

more likely than

not that some

portion or

all of

the deferred

tax assets

will not

be realized.

The ultimate

realization

of deferred

tax assets

is dependent

upon the generation of

future taxable income

during the periods

in which those temporary

differences become deductible.

Management considers the scheduled reversal

of deferred tax liabilities, projected future taxable

income, and tax planning

strategies in making this assessment.

The U.S.

Federal jurisdiction

and Florida

are the

major tax

jurisdictions where

the Company

files income

tax returns.

The Company is generally no longer subject to U.S. Federal or

State examinations by tax authorities for years before 2020.

For

the

years

ended

December 31,

2022,

the

Company

did

no

any unrecognized

tax benefits

as a

result of

Additionally,

no

Scholes

option

pricing

model and

accounts

for this

expense

using

a prorated

straight-line

amortization

method over

the

period

of

the

option.

Stock-based

compensation

expense

is

based

on

awards

that

the

Company

OFF-BALANCE SHEET ARRANGEMENTS

The Company is a party to financial instruments with off-balance-sheet risk in the normal course of business in order to

meet the financial

needs of

its customers

and to reduce

its own

exposure to

fluctuations in

interest rates.

These financial

instruments include

unfunded commitments

under lines

of credit,

commitments to

extend credit,

standby and

commercial

letters of

credit. Those

instruments involve,

to varying

degrees, elements

of credit

and interest

rate risk

in excess

of the

amount recognized in the Company’s Consolidated Balance Sheets. The Company uses the

same credit policies in making

commitments and conditional obligations as it does for

on-balance-sheet instruments.

The Company's

exposure to credit

loss in the

event of nonperformance

by the other

party to the

financial instruments

for unused lines of credit, and standby letters of credit

is represented by the contractual amount of these commitments.

On

January

1,

2023,

the

Company

adopted

ASU

2016-13

Financial

Instruments

-

Credit

Losses

(Topic

326):

Measurement of Credit Losses

on Financial Instruments,

as amended, which replaces

the incurred loss methodology

with

an expected

loss methodology

that is

referred to as

the CECL

methodology.

The measurement

of expected

credit losses

under the CECL methodology

is applicable to financial

assets measured at amortized

cost, including loan receivables

and

held-to-maturity debt

securities. Prior

to the adoption

of ASC 326

on January

2023, the allowance

for credit

losses was

a

valuation allowance for probable incurred credit losses.

The Company

records

a

liability

for

expected

credit

losses

on

off-balance-sheet

credit

exposure

in

accordance

with

ASC

326.

The

Company

uses

the

loss

rate

and

exposure

of

default

framework

to

estimate

a

reserve

for

unfunded

commitments. Loss rates

for the expected funded

balances are determined

based on the

associated pooled loan

analysis

loss rate and the exposure at default is

based on an estimated utilization given

default. The off-balance sheet commitment

allowance were $

372

thousand and $

166

thousand as of December 31, 2023 and December 31,

2022, respectively.

Standby and commercial letters of credit

4,320

Total

$

$

99,781

Commitments to

extend credit

are agreements

to lend

to a

customer as

long as

there is

no violation

of any

condition

established in the contract. Commitments generally have

fixed expiration dates or other termination clauses.

Unfunded lines of

credit and revolving

credit lines are

commitments for possible

future extensions

of credit to

existing

customers. These lines of

credit are uncollateralized and

usually do not contain

a specified maturity date

and ultimately may

not be drawn upon to the total extent to which the Company

is committed.

Standby

and

commercial

letters

of

credit

are

conditional

commitments

issued

by

the

Company

to

guarantee

the

performance of a

customer to

a third

party. Those letters of

credit are

primarily issued to

support public and

private borrowing

arrangements. Essentially all letters of credit have fixed maturity dates and many of them expire without being drawn upon,

they do not generally present a significant liquidity risk

to the Company.

DERIVATIVES

The Company utilizes interest rate swap agreements

as part of its asset-liability management strategy to help

manage

its interest

rate risk

position. The

notional amount

of the

interest rate

swaps do

not represent

amounts exchanged

by the

parties. The amounts exchanged are

determined by reference to

the notional amount and the

other terms of the individual

interest rate swap agreements.

Rate Swaps Designated as Cash Flow Hedges

As of December

31, 2023,

the Company had

two

interest rate swap

agreements with

a notional aggregate

amount of

$

50

million that were designated as cash flow hedges of certificates of deposit. The interest rate swap agreements have an

average

maturity

of

2.38

years,

the

weighted

average

fixed-rate

paid

is

3.59

Interest Rate Swaps Designated as Fair Value

Hedges

As of December

31, 2023, the

Company had

four

interest rate swap

agreements with a

notional aggregate amount

of

$

200

million

that

were

designated

as

fair

value

hedges

on

loans.

The

interest

rate

swap

agreements

have

an

average

maturity of

2.23

years, the weighted average fixed-rate paid

is

4.74

%, with the weighted average

3-month compound SOFR

being received.

The

changes

in

fair

value

on

these

interest

rate

swaps

are

recorded

in

other

assets

or

other

liabilities

with

a

corresponding recognition in the assets being hedged.

Interest Rate Swaps

The Company also

enters into

interest rate swaps

with its

loan customers. The

Company had

20

and

15

interest rate

swaps with loan customers with a notional aggregate

amount of $

46.5

million and $

33.9

million at December 31, 2023 and

2022, respectively.

These interest rate

swaps have maturity

dates of between

2025 and 2051.

The Company entered

into

corresponding

and

offsetting

derivatives

with

third

parties.

The

fair

value

of

liability

on

these

derivatives

requires

the

Company to provide the counterparty

with funds to be held as collateral

which the Company reports as other

assets under

the Consolidated

Balance Sheets.

While these

derivatives represent

economic hedges,

they do

not qualify

as hedges

for

accounting purposes.

FAIR VALUE

MEASUREMENTS

Determination of Fair Value

The Company

uses

fair value

measurements

to record

fair-value

adjustments

to certain

assets

and liabilities

and to

determine fair value

disclosures. In accordance

with the fair

value measurements

accounting guidance, the

fair value of

a

financial instrument is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction

between market

participants

at the

measurement

date.

Fair value

is best

determined based

upon quoted

market prices.

However, in

many instances, there

are no quoted

market prices for the

Company's various financial

instruments. In cases

where quoted

market prices

are not

available, fair

values are

based on

estimates using

present value

or other

valuation

techniques. Those techniques are significantly affected by the assumptions used, including the discount rate and estimates

of future cash flows. Accordingly, the fair value estimates may not be realized in

an immediate settlement of the instrument.

The fair

value guidance provides

a consistent definition

of fair

value, which focuses

on exit

price in

an orderly transaction

(that is,

not a

forced

liquidation

or distressed

sale) between

market participants

at the

measurement

date

under current

market conditions.

If there

has been

a significant

decrease

in the

volume

and level

of activity

for the

asset

or liability,

a

change in

valuation technique or

the use

of multiple

valuation techniques may

be appropriate.

In such

instances, determining

the

price

at

which

willing

market

participants

would

transact

at

the

measurement

date

under

current

market

conditions

depends on the facts

and circumstances and

requires the use of

significant judgment. The fair

value is a reasonable

point

within the range that is most representative of fair value under

current market conditions.

Fair Value Hierarchy

In accordance with

this guidance, the

Company groups its

financial assets

and financial liabilities

generally measured

at fair

value in

three

levels, based

on the

markets

in which

the assets

and liabilities

are traded,

and the

reliability

of the

assumptions used to determine fair value.

Level 1

  • Valuation

is based

on quoted

prices in

active markets

for identical

assets or

liabilities that

the reporting

entity has

the ability

to access

at the measurement

date. Level

1 assets

and liabilities

generally include

debt and

equity securities that

are traded in

an active exchange

market. Valuations are obtained from

readily available pricing

sources for market transactions involving identical assets

or liabilities.

Level 2

  • Valuation

is based on inputs other

than quoted prices included

within Level 1 that are

observable for the

asset

or

liability,

either

directly

or

indirectly.

The

valuation

may

be

based

on

quoted

prices

for

similar

assets

or

liabilities; quoted

prices in

markets that are

not active;

or other inputs

that are observable

or can be

corroborated

by observable market data for substantially the full term of the

asset or liability.

Level 3

  • Valuation

is based on

unobservable inputs that

are supported

by little or

no market activity

and that are

significant

to

the

fair

value

of

the

assets

or

liabilities.

Level

3

assets

and

liabilities

include

financial

instruments

whose value

is determined

using pricing

models, discounted

cash

flow

methodologies,

or similar

techniques,

as

well as instruments for which determination of fair value

requires significant management judgment or estimation.

A

financial

instrument's

categorization

within

the

valuation

hierarchy

is

based

upon

the

lowest

level

of

input

that

is

significant to the fair value measurement.

Items Measured at Fair Value

on a Recurring Basis

Investment securities:

When instruments are traded

in secondary markets and

quoted market prices do

not exist for

such securities,

management generally

relies on

prices obtained

from independent

vendors or

third-party broker

-dealers.

Management reviews pricing methodologies provided by the vendors and third-party broker-dealers in order to determine if

observable market information is being utilized. Securities measured with pricing provided by independent vendors or

third-

party broker-dealers

are classified within

Level 2 of

the hierarchy and

often involve using

quoted market

prices for similar

securities, pricing models or discounted cash flow analyses

utilizing inputs observable in the market where available.

Derivatives:

The

fair

value

of

derivatives

are

measured

with

pricing

provided

by

third-party

participants

and

are

classified within Level 2 of the hierarchy.

The following table represents

Items Measured at Fair Value

on a Non-recurring Basis

Individually Evaluated

Loans and

Impaired Loans:

ASC 326

eliminates the

current accounting

model for

impaired

loans effective as

of January 1,

  1. At

December 31, 2022,

in accordance

with provisions

of the

loan impairment

guidance,

individual loans

with a

carrying amount

of $

3.9

million were

written down

to their

fair value

of $

3.6

million, resulting

in an

impairment charge of $

294

thousand, which was included

in the allowance for

credit losses at December

31, 2022. Loans

subject to write

-downs, or

impaired loans,

are estimated

using the present

value of

expected cash

flows or the

appraised

value

of

the

underlying

collateral

discounted

as

necessary

due

to

management's

estimates

of

changes

in

economic

conditions and are considered a Level 3 valuation.

Other Real Estate:

Other real

estate owned are

valued at the

lesser of the

third-party appraisals

less management's

estimate of

the costs to

sell or the

carrying cost of

the other

real estate

owned. Appraisals generally

use the market

approach

valuation technique

and use

market observable

data to

formulate an

opinion of

the fair

value of

the properties.

However,

the appraiser

uses professional

judgment in

determining the

fair value

of the

property and

the Company

may also

adjust

the value for changes in

market conditions subsequent

to the valuation date

when current appraisals

are not available. As

a consequence of the carrying cost or the

third-party appraisal and adjustments therein, the fair values of the properties are

considered a Level 3 valuation.

EARNINGS PER SHARE

Earnings

per

share

(“EPS”)

for

common

stock

is

calculated

using

the

two-class

method

required

for

participating

securities. Basic EPS

is calculated by

dividing net income

(loss) available to

common stockholders by the

weighted-average

number of common shares outstanding for

the period, without consideration for common

stock equivalents. Diluted EPS is

computed by

dividing net

income (loss)

available to

common stockholders

by the

weighted-average

number

of common

shares outstanding for

the period and

the weighted-average number

of dilutive common

stock equivalents outstanding

for

the period determined using the treasury-stock method. For

purposes of this calculation, common stock equivalents include

common stock options and are only included in the calculation

of diluted EPS when their effect is dilutive.

REGULATORY

MATTERS

Banks and

bank holding

companies

are subject

to regulatory

capital requirements

administered by

federal and

state

banking

agencies.

Failure

to

meet

minimum

capital

requirements

can

initiate

certain

mandatory

and

possibly

additional

discretionary actions

by regulators

that, if

undertaken, could

have a

direct material

effect on

the Company's

consolidated

financial

statements.

Under

capital

adequacy

guidelines

and

the

regulatory

framework

for

prompt

corrective

action,

the

Company and the

Bank must meet

specific capital guidelines

that involve quantitative

measures of their

assets, liabilities,

and certain

off-balance-sheet

items as

calculated under

regulatory accounting

practices. The

Company’s and

the Bank’s

capital

amounts

and

classification

are

also

subject

to

qualitative

judgments

by

the

regulators

about

components,

risk

weightings, and other factors.

Based on changes to the Federal Reserve’s definition of a “Small Bank

Holding Company” that increased the threshold

to $3.0 billion in assets

in August 2018, the Company

is not currently subject to

separate minimum capital measurements.

At such time when the Company reaches the

$3.0 billion asset level, it will

be subject to capital measurements independent

of the Bank.

The Bank

elected to

permanently opt-out

of the

inclusion of

accumulated other

comprehensive income

in the

capital

calculations, as

permitted by the

regulations. This

opt-out reduces

the impact of

market volatility on

the Bank’s

regulatory

capital levels.

The Bank is

subject to the

rules of the

Basel III regulatory capital

framework and related Dodd-Frank

Wall Street Reform

and Consumer Protection

Act. The rules include

the implementation of

a

2.5

% capital conservation

buffer that is

added to

the minimum requirements

for capital adequacy

purposes. Failure

to maintain the

required capital conservation

buffer will

limit the ability of

the Bank to pay

dividends, repurchase shares

or pay discretionary

bonuses. At December

31, 2023 and

2022, the capital ratios for the Bank were sufficient

to meet the conservation buffer.

Prompt

corrective

action

regulations

provide

five

classifications:

well

capitalized,

adequately

capitalized,

undercapitalized,

significantly

undercapitalized,

and

critically

undercapitalized,

although

these

terms

are

not

used

to

represent overall financial condition. If

adequately capitalized, regulatory approval

is required to accept brokered

deposits.

Table of Contents

USCB Financial Holdings, Inc.

2023 10-K

If

undercapitalized,

capital

distributions

are

limited,

as

is

asset

growth

and

expansion,

and

capital

restoration

plans

are

required.

At December 31,

2023 and

2022, the

most recent

notification from

the regulatory

authorities categorized

the Bank

as

well capitalized

under the

regulatory framework

for prompt

corrective action.

Failure to

meet statutorily

mandated capital

guidelines

could

subject

the

Bank

to

a

variety

of

enforcement

remedies,

including

issuance

of

a

capital

directive,

the

termination of deposit

insurance by the

The Company

is limited in

the amount

of cash

dividends that

it may

pay.

Payment of dividends

is generally

limited to

the Company’s

net income

of the

current year

combined with

the Bank’s

retained income

of the

preceding two

years, as

defined by state banking regulations. However, for any dividend declaration, the Company must consider

additional factors

such as the amount

of current period net

income, liquidity,

asset quality,

capital adequacy and

economic conditions at

the

Bank. It is likely that

these factors would further limit the

amount of dividends which the Company could

declare. In addition,

bank

regulators

have

the

authority

to

prohibit

banks

from

paying

dividends

including

dividends

to

their

parent

holding

company, if they deem

such payment to be an unsafe or unsound practice.

Item 9.

Changes in and Disagreements with Accountants on

Accounting and Financial Disclosure

None.

Item 9A. Controls and Procedures

Evaluation of Disclosure Controls and Procedures

Under the supervision and with the participation of our management, including our Chief Executive Officer and its

Chief

Financial

Officer,

we

evaluated

the

effectiveness

of

the

design

and

operation

of

the

Company’s

disclosure

controls

and

procedures

as

of

December 31,

2023.

Based

on

that

evaluation,

management

believes

that

the

Company’s

disclosure

controls

and

procedures

were

effective

to

collect,

process,

and

disclose

the

information

required

to

be

disclosed

in

the

reports filed or

submitted under

the Exchange

Act within the

required time

periods as of

the end of

the period covered

by

this Report.

This

annual

report

does

not

include

an

integrated

audit

report

of

the

Company's

registered

public

accounting

firm

regarding

internal

control

over

financial

reporting.

Management's

report

was

not

subject

to

audit

by

the

Company's

registered public accounting

firm pursuant to

temporary rules

of the Securities

and Exchange Commission

that permit the

Company (non-accelerated filer) to provide only management's

report in this annual report.

Management’s Report on Internal Control

over Financial Reporting

Management is responsible for designing, implementing, documenting, and

maintaining an adequate system of internal

control over financial

reporting, as

such term

is defined

in the Exchange

Act. An

adequate system

of internal control

over

financial reporting encompasses the processes and procedures

that have been established by management to:

maintain records that accurately reflect the Company’s

transactions;

prepare

financial

statement

and

footnote

disclosures

in

accordance

with

U.S.

GAAP

that

can

be

relied

upon

by

external users; and

prevent and detect unauthorized acquisition, use or disposition of the Company's assets that could have a material

effect on the financial statements.

Management conducted

an evaluation

of the

effectiveness

of the

Company's

internal control

over financial

reporting

based on the criteria in Internal Control-Integrated Framework issued by the Committee of Sponsoring Organizations of

the

Treadway

Commission

(COSO).

Based

on

this

evaluation

under

the

criteria

in

Internal

Control-Integrated

Framework,

management concluded that

internal control over financial

reporting was effective

as of December 31,

  1. Furthermore,

during the conduct of its assessment, management identified no material weakness in

its financial reporting control system.

The Board of USCB

Financial Holdings, Inc., through its

Audit Committee, provides oversight to

management’s conduct

of

the

financial

reporting

process.

The

Audit

Committee,

which

is

composed

entirely

of

independent

directors,

is

also

responsible for the appointment of the independent registered public accounting firm. The

Audit Committee also meets with

management, the internal audit staff,

and the independent registered public accounting

firm throughout the year to provide

assurance as to the adequacy of the

financial reporting process and to monitor the

overall scope of the work performed by

the internal audit staff and the independent public accountants.

Because of its inherent limitations, the disclosure controls and

procedures may not prevent or detect misstatements.

A

control system, no matter how well conceived and operated, can only provide reasonable, not absolute, assurance that the

objectives of the control system are met. Because

of the inherent limitations in all control systems, no

evaluation of controls

can provide absolute assurance that all control issues and instances of

fraud, if any,

have been detected. Also, projections

of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of

changes in conditions or that the degree of compliance with the

policies or procedures may deteriorate.

Changes in Internal Control Over Financial Reporting

There has been

no change in

our internal control

over financial reporting

(as defined in

Rules 13a-15(f) and

15d-15(f)

under the

Exchange Act)

during our

most recent

fiscal quarter

that has

materially affected, or

is reasonably

likely to

materially

affect, our internal control over financial reporting.

designated Class B Non-Voting Common Stock,

par value $1.00

per share (“Class B

Common Stock” and together with the

Class

A Common Stock, the “Common Stock”), and (b) 15,600,000

shares of preferred stock, $1.00 par value per share.

Voting Rights

The Class A Common Stock has voting rights, and Class B Common Stock does not have voting rights

except in limited

circumstances. Holders

of Class

A Common

Stock are

entitled to

one vote

per share

on all

matters on

which the

holders are

entitled to vote, except in the case of amendments to the Articles of Incorporation where such amendment relates solely to

Class

B

Common

Stock

or

any

other

series

of

the

Company’s

preferred

stock.

The

Company

does

not

have

any cumulative

votes

in

the

election

of

directors.

Under

the

Bylaws,

unless

otherwise

provided

by

law

or

the

Articles

of Incorporation,

the

holders of

a majority

of shares

issued, outstanding,

and entitled

to vote,

present in

person or

by proxy, will

constitute

a

quorum

to

transact

business,

including

the

election

of

directors,

except

that

when

a specified

item

of business is required

to be voted on by one or

more designated classes or series

of capital stock, a majority of the shares of each such

class or

series

will

constitute a

quorum. Once

a quorum

is present,

except as

otherwise provided

by law,

the Articles of Incorporation,

the

Bylaws or

in respect of the

election of directors,

all matters to be

voted on by the

Company’s shareholders must

be approved

by a majority of shares constituting a quorum, and where a separate vote by class or series is required, a majority of the

votes

represented

by the shares of the shareholders

of such

class or series present in person

or by proxy and entitled to

vote shall be

the act of such

class or series. The affirmative

vote of the holders representing

66 2/3% of the then outstanding shares

of Class

A Common Stock is required to

amend, alter or repeal, or adopt any provision as part of the

Articles of Incorporation that is

inconsistent with the purpose and intent

of certain designated provisions of the Articles

of

Incorporation

and

the

Bylaws

including,

among

others,

perpetual

term,

management

of

the

Company, indemnification,

transfer restrictions, board powers

and number

of directors.

The holders of Class B Common Stock

have

limited voting rights. In

addition to any voting rights that may

be required under

Florida

law,

the

consent of

holders

of Class

B

Common

Stock

representing a

majority

of the

shares of

Class

B Common

Stock present in person

or by proxy and entitled

to vote, voting as a separate

class, is required to (a)

amend the Articles of

Incorporation in

a manner

that would significantly and

adversely affect

the rights of the

holders of the Class

B Common

Stock in

a manner

that

is

different

from

the effect

of such

amendment

on the

Class

A

Common

Stock or

(b) liquidate, dissolve or wind-

up the Company.

Dividends

Holders of Common Stock are

entitled to receive such dividends

as may from time to time be declared by the Company’s Board

of Directors (the

“Board”) out of funds

legally available

for such purposes. The

Company can

pay dividends on its Common Stock

only if it has paid or provided for

the payment of all dividends, if any, to which

holders of its then outstanding preferred stock, are

entitled. The Company’s ability to

pay dividends is also subject to applicable

federal and state

banking laws.

Liquidation

In the event of

the liquidation, dissolution

or winding-up of the Company,

holders of both Class A Common

Stock and Class B

Common Stock are entitled to

share equally and ratably in our

assets, if any,

remaining after the payment of all

the Company’s

debts

and liabilities, and the

satisfaction of the liquidation

preferences of the holders

of any then outstanding classes

or series of

preferred stock.

Preemptive Rights,

Redemption or

Other Rights

Pursuant to the Articles

of Incorporation and the Bylaws, holders of Common

Stock do not have preemptive rights

or other

rights to purchase,

subscribe for or take

any part of any shares

of the Company’s

capital stock. The Large

Investors (as defined

herein), however, have certain contractual

preemptive rights pursuant to the Side Letter Agreement. In addition, the

Company

does

not

have

any

sinking

fund

or

redemption

provisions

in

the

Articles

of

Incorporation

or

the

Bylaws applicable to its

Common Stock.

Conversion

The

Class

A

Common

Stock

does

not

have

any

conversion

rights.

Pursuant

to

the

Articles

of

Incorporation,

the

Company’s shares of Class

B Common

Stock may only be transferred (a) to an affiliate

of

the holder of Class B Common

Stock,

(b) to the Company,

(c) pursuant to a widespread public

distribution of the Common Stock

(including a transfer to an underwriter

for

the purpose of conducting a widespread public distribution or pursuant to Rule 144 under the Securities Act),

(d) if no transferee or group of associated transferees would receive 2% or more of any class of capital stock entitled to vote

generally in the election of

directors of the Company or (e) to

a transferee that would

control more than 50% of the

capital stock

entitled

to

vote

generally

in

the

election

of

directors

of

the

Company

without

any

transfer

from

the

transferor.

Immediately following

a transfer

of the

type described

in (c),

(d) or

(e) in

the preceding

sentence, each

share of

Class B

Common Stock so transferred is

automatically

converted into one share of Class

A Common

Stock (subject to adjustment as

provided in the Articles of Incorporation). The Company must at

all times reserve and keep available out of its authorized and

unissued

shares of

Class A

Common Stock

such number

of shares

of Class

A Common Stock

that

may be

issuable upon

conversion of all of the outstanding

shares of Class

B Common Stock.

Stockholder

Meetings

Except as otherwise provided by law,

the Board, or any one or more

shareholders owning, in the aggregate,

not less than

ten percent of the issued and

outstanding Class A Common Stock,

may call a special meeting of

shareholders

at any time for

any purpose not inconsistent with

the Articles

of Incorporation or the Bylaws.

Director Removal

Subject to the rights of holders of any class

or series of preferred stock with

respect to the election of directors, a director may

be removed from office by the affirmative

vote of holders of shares of capital stock issued and outstanding and entitled

to vote in

an election of directors representing

at least a majority of the

votes entitled to be cast thereon,

and then,

only for cause.

Anti-takeover Effects

Certain provisions of the Articles

of Incorporation, the Bylaws,

Florida and U.S. banking laws to

which the Company is subject

may have anti-takeover effects

and may delay, defer, or prevent a tender

offer or takeover attempt that

a shareholder might consider

to be

in such

shareholder’s best

interest, including

those attempts

that might

result in a

premium over the market

price

for the

shares held by

shareholders, and may make

removal of management

more difficult.

The Articles

of Incorporation and Bylaws

include provisions that:

empower the Board, without shareholder approval, to

issue preferred stock, the terms

of which, including voting

power, are to

be set by the

Board;

provide that directors

may be removed from office

only for cause and only upon

a majority vote of the shares

of capital stock entitled

to vote in an election

of directors;

prohibit holders of Class

A Common Stock from

taking action by written consent in

lieu of a

shareholder meeting;

require holders of at least 10%

of the Company’s Class

A Common Stock in order

to call a special

meeting;

do not provide for cumulative voting in elections of

Company

directors;

provide that the Board has the

authority to amend the Bylaws;

require shareholders that

wish to bring business

before annual or

special meetings of

shareholders, or to

nominate

candidates for

election as directors

at an annual

meeting of shareholders,

to provide timely

notice of their

intent in

writing and satisfy disclosure requirements;

and

enable the Board

to increase, between

annual

meetings, the number

of persons serving

as directors

and to fill

the

vacancies created as a result of the increase

until the next meeting of shareholders by a

majority vote of the directors

present at a meeting of directors.

Additionally,

the Articles of Incorporation

prohibit any direct or

indirect transfer of stock

or options to acquire

stock to any

person

who,

as a

result

of the

transfer,

would own

4.95% or

more

of the

Company’s

capital

stock, as

long as

the

Company continues to have “deferred

tax assets,” subject to limited

exceptions as provided in the Articles

of Incorporation. Also,

certain provisions of

Florida law may delay,

discourage,

or prevent an attempted acquisition

or change

in control. Furthermore,

banking laws impose notice, approval, and ongoing regulatory requirements on any shareholder or other party that seeks to

acquire direct or indirect “control”

of a bank holding company,

which includes the Change in Bank

Control Act and the Bank

Holding Company Act.

Preferred Stock

The Board is authorized, without

shareholder approval

and subject to any limitations prescribed

by law, the

Articles of

Incorporation and the Bylaws,

at any time or from

time to time to (a) provide for the

issuance of the shares of preferred stock in

one or more classes

or series, (b) determine the

designation for any such classes or series of preferred

stock, (c) establish the

number

of

shares

to

be

included

in

any

such

class

or

series,

and

(d)

determine

the

terms,

powers,

preferences,

qualifications, limitations, restrictions

and relative, participating,

optional or other

special rights of the

shares of such

class or

series of preferred stock, which include rights such as those with respect to dividends, liquidation preference, conversion,

redemption, and/or voting.

Any issuance of preferred stock with voting rights

or which is convertible into voting

shares could adversely affect the voting

power of the holders of Class

A Common Stock.

Any of aforementioned actions could have

an anti-takeover

effect.

Side

Letter

Agreement

Pursuant to

the Side

Letter Agreement

between the

Company,

Priam Capital

Fund II,

LP (“Priam”),

Patriot Financial

Partners II,

L.P.

(“Patriot Financial”) and Patriot Financial

Partners Parallel

II, L.P.

(“Patriot Financial

Partners,” together with

Patriot Financial and Priam, the “Large

Investors”), the Company is required

to maintain its Board at no less than five

nor more

than

seven directors,

and to cause

one person nominated

by

each Large Investor

to be elected

or appointed to

the Board,

including filling

any vacancy

(the “Board

Representative”), subject to satisfaction

of all

legal and

governance requirements

regarding such Board Representative’s

service as a director.

Such Board Representative rights last as

long as each Large

Investor beneficially owns shares of the Common

Stock representing

50% or more of the common stock of the

Bank (as defined

below) purchased by the

Large Investor in the recapitalization of U.S. Century

Bank, the Company’s wholly

owned Florida

state-chartered bank subsidiary (the

“Bank”),

in 2015 (the “2015 Recapitalization”),

as adjusted from time to time as a

result

of

changes in capitalization. Pursuant

to the Side Letter Agreement,

the Large Investors

have the power

to

designate

a

Board

observer

to

attend

meetings

in

a

nonvoting

capacity

in

the

event

any

applicable

Board Representative is

unable to

attend

such

meetings or

if the

Large Investor

does not

have a

Board Representative

on the Board on the date of

any meeting.

The Side Letter Agreement provides

each Large Investor with matching stock rights

for

so long as each Large Investor

beneficially owns shares of Common Stock

representing 50% or more of the common

stock of the

Bank purchased by the Large

Investor

in the 2015

Recapitalization,

as

adjusted from time

to time as

a result of

changes in capitalization.

The matching

stock rights

permit each Large Investor to purchase new equity

securities

offered by the Company for the

same price

and on

the same

terms

as

such securities

are

proposed to

be offered

to

others,

subject

to specified

exceptions, procedural

requirements

and compliance with applicable

bank regulatory ownership requirements

as further

described in the Side Letter

Agreement. The Side Letter Agreement

also provides customary information

rights to the

Large Investors.

Bank

(the “

any recovery under this Policy

involving such officer or employee).

Covered Executives; Incentive-Based Compensation

This Policy

applies to

Incentive-Based Compensation

received by

a Covered

Executive (a)

after

beginning service as a Covered Executive; (b) if that

person served as a Covered Executive at any

time

during

the

performance

period

for

such

Incentive-Based

Compensation;

and

(c)

while

the

Company had

a listed

class of

securities on

a national

securities exchange.

This Policy

does not

apply to

Incentive-Based Compensation

received by

a Covered

Executive: (1)

while that

person

was serving

in a

non-executive capacity

prior to

becoming a

Covered Executive

or (2)

who is

a

Covered

Executive

on

the

date

on

which

the

Company

is

required

to

prepare

an

Accounting

Restatement but who was not a Covered Executive at any time

during the performance period for

which the Incentive-Based Compensation is received.

5.

Required

Recoupment

of

Erroneously

Awarded

Compensation

in

the

Event

of

an

Accounting Restatement

In the event

the Company

is required to

prepare an

Accounting Restatement,

the Company shall

reasonably promptly recoup

the amount of

any Erroneously Awarded

Compensation received by

any

Covered

Executive,

as

calculated

pursuant

to

Section

5

hereof,

relating

to

the

Applicable

Period.

6.

Erroneously Awarded

Compensation: Amount Subject to Recovery

The

amount

of

“Erroneously

Awarded

Compensation”

subject

to

recovery

under

the

Policy,

as

determined by the Administrator, is the amount of Incentive-Based

Compensation received by the

Covered Executive

that

exceeds

the

amount

of

Incentive-Based Compensation

that

would

have

been received

by

the

Covered

Executive

had

such

compensation

been determined

based on

the

restated amounts.

Erroneously Awarded

Compensation

shall be

computed

by the

Administrator without

regard

to

any taxes

paid by

the Covered

Executive in

respect of

the Erroneously

Awarded

Compensation.

By way

of example,

with respect

to any

compensation plans

or programs

that take

into account

Incentive-Based

Compensation,

the

amount

of

Erroneously

Awarded

Compensation

subject

to

recovery hereunder includes, but is not limited to, the amount contributed to any notional account

based on Erroneously

Awarded

Compensation and

any earnings accrued

to date on

that notional

amount.

Effective as of: 12/01/2023

For

Incentive-Based

Compensation

based

on

stock

price

or

TSR:

(a)

the

Administrator

shall

determine the amount

of Erroneously Awarded

Compensation based

on a reasonable

estimate of

the

effect

of

the

Accounting

Restatement

on

the

stock

price or

TSR

upon

which

the

Incentive-

Based

Compensation

was

received;

and

(b)

the

Company

shall

maintain

documentation

of

the

determination of

that reasonable

estimate and

provide such

documentation to

The Nasdaq

Stock

Market (“Nasdaq”) and the Covered Executive(s).

7.

Method of Recoupment

The

Administrator

shall

determine, in

its

sole

discretion, the

timing

and

method

for

reasonably

promptly recouping Erroneously

Awarded

Compensation hereunder,

which may

include without

limitation

(a)

seeking

reimbursement

of

all

or

part

of

any

cash

or

equity-based

award,

(b)

cancelling prior

cash or

equity-based awards,

whether vested

or unvested

or paid

or unpaid,

(c)

cancelling or offsetting

against any

planned future

cash or

equity-based awards,

(d) forfeiture of

deferred compensation, subject to compliance

with Section 409A of the Internal

Revenue Code of

1986, as amended (“IRC”) and the regulations promulgated thereunder,

and (e) any other method

authorized

by

applicable

law

or

contract.

Subject

to

compliance

with

any

applicable

law,

the

Administrator may

affect

recovery under

this

Policy from

any amount

otherwise payable

to the

Covered Executive, including amounts payable to such individual under any otherwise applicable

Company

plan,

program

or

contract,

including

base

salary,

bonuses

or

commissions

and

compensation previously deferred by the Covered Executive.

The Company is

authorized and directed

pursuant to

this Policy to

recoup Erroneously Awarded

Compensation in

compliance with

this Policy

unless the

Compensation Committee

of the

Board

has determined that recovery would be impracticable solely for

the following limited reasons, and

subject to the following procedural and disclosure requirements:

The direct expense paid to a third

party to assist in enforcing the Policy

would exceed

the amount

to be

recovered. Before

concluding that

it would

be impracticable

to recover

any amount of Erroneously Awarded Compensation based on expense

of enforcement,

the

Administrator

must

make

a

reasonable

attempt

to

recover

such

Erroneously

Awarded

Compensation, document such reasonable attempt(s)

to recover and provide

that documentation to Nasdaq;

Recovery

would

violate

any

law

of

the

United

States

that

was

adopted

prior

to

November 28, 2022.

Before concluding that

it would

be impracticable to

recover any

amount

of

Erroneously

Awarded

Compensation

based

on

a

violation

of

law,

the

Administrator must satisfy the applicable opinion and disclosure requirements of Rule

10D-1 and the Listing Standards; or

Recovery would likely

cause an

otherwise tax-qualified

retirement plan, under

which

benefits

are

broadly

available

to

employees

of

the

Company,

to

fail

to

meet

the

requirements

of

Sections

401(a)(13)

or

411(a)

of

the

IRC

and

the

regulations

thereunder.

If

litigation

becomes

necessary to

collect

any

Erroneously

Awarded

Compensation

recoverable

under this Policy,

the Company shall

be entitled to

recover from the

Covered Executive(s) all

of

its reasonable attorneys’ fees and costs of enforcement or collection.

8.

No Additional Payments

In no event shall the Company be required to award Covered Executives an additional payment if

the Accounting Restatement results in a higher Incentive-Based Compensation payment.

9.

No Indemnification or Reimbursement of Covered Executives

Notwithstanding the

terms of

any other

policy,

program, agreement

or arrangement,

in no

event

will the Company or any of its affiliates indemnify or

reimburse a Covered Executive for any loss

under

this

Policy

and

in

no

event

will

the

Company

or

any

of

its

affiliates

pay

premiums

or

reimburse the Covered Executive for premiums he or she

paid on any insurance policy that would

cover

a

Covered

Executive’s

potential

obligations

with

respect

to

Erroneously

Awarded

Compensation under this Policy.

10.

Administrator Indemnification

Any

members

of

the

Administrator,

and

any

other

members

of

the

Board

or

officers

of

the

Company

who

assist

in

the

administration

of

this

Policy,

shall

not

be

personally

liable

determination

or

interpretation

made

with

respect

to

this

Policy

and

shall

be

fully

indemnified by the Company to the fullest

extent under applicable law and Company policy

with

respect to any such action, determination

or interpretation. The foregoing sentence shall

not limit

any other rights

to indemnification of the

members of the

Board under applicable law

or Company

policy.

11.

Incentive-Based Compensation that

is received by

Covered Executives

the generality of

Section

7 hereof,

and subject

to applicable

law,

the Administrator

may affect

recovery under

this Policy

from any

amount of

compensation

approved, awarded,

granted, payable

or paid

to the

Covered

Executive

prior

to,
