Q1 2024 Form 10-Q

SUMMARY OF SIGNIFICANT ACCOUNTING

POLICIES

Overview

USCB Financial Holdings,

Inc.,

a Florida corporation

incorporated in 2021,

is a bank

holding company with

one direct

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.

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 Title LLC began operations

in 2021.

Basis of Presentation

The accompanying unaudited consolidated financial statements have been prepared in accordance with instructions to

Form 10-Q and

do not include all

the information and

footnotes required by U.S.

generally accepted accounting

principles

(“U.S.

GAAP”)

for

complete

financial

statements.

All

adjustments

consisting

normally

recurring

accruals

that,

the

opinion

management,

are

necessary

for

fair

presentation

the

financial

position

and

results

operations

for

the

periods presented

have been

included. These

unaudited consolidated

financial statements

should be

read in

conjunction

with

the

Company’s

consolidated

financial

statements

and

notes

appearing

in the

Company’s

Annual

Report

Form 10-K for the year ended December 31, 2023.

Principles of Consolidation

The

Company

consolidates

entities

which

has

controlling

financial

interest.

Intercompany

transactions

and

balances are eliminated in consolidation.

Use of Estimates

To prepare

financial statements in conformity with U.S. GAAP,

management makes estimates and assumptions based

on available

information. These

estimates and

assumptions affect

the amounts

reported in

the financial

statements. The

most significant

estimates impacting

the Company’s

consolidated financial

statements are

the allowance

for credit

losses

(“ACL”) and income taxes.

Reclassifications

Certain amounts in the consolidated financial statements have been reclassified to conform

to the current presentation.

Reclassifications had no impact on the net income or stockholders’

equity of the Company.

Recently Issued Accounting Standards

Adoption of New Accounting Standards

Reference Rate Reform

March

2020,

the

Financial

Accounting

Standards

Board

(“FASB”)

issued

ASU

2020-04,

Reference

Rate

Reform

(Topic

848), aiming to facilitate the impacts

of reference rate reform on financial reporting.

This initiative was subsequently

clarified

January

2021

through

ASU

2021-01,

providing

optional

directives

for

designated

timeframe

alleviate

challenges

associated

with

accounting

for,

or acknowledging

the

effects

of, reference

rate reform

on financial

reporting.

These

amendments

offer

discretionary

guidance

for

defined

period

alleviate

potential

accounting

complexities

associated with reference rate reform in financial reporting. The

expedients and exceptions provided by these amendments

are not

applicable to

contract modifications

executed and

hedging relationships

initiated or

reviewed after

December 31,

2022, except

for

pre-existing

hedging

relationships

of December

31,

2022,

for

which

entity

has

opted

for

specific

optional expedients, and which

are retained until the conclusion

of the hedging relationship.

Additionally,

the amendments

permit entities to make a one-time choice to divest, transfer,

or both divest and transfer debt securities categorized as held

to maturity, referencing a rate impacted by reference rate reform,

and classified as held to maturity

prior to January 1, 2020.

In December 2022, the

FASB issued new guidance extending the

expiration date of this

guidance from December 31,

2022,

to December

31, 2024,

after which

entities will

no longer

be authorized

to apply

the relief

provided under

this guidance.

Q1 2024 Form 10-Q

Before this recent guidance, these amendments were effective for all entities

from March 12, 2020, to December 31, 2022.

The

Company

executed

its

transition

strategy

preparation

for

the

cessation

the

London

Intrabank

Offered

Rate

(“LIBOR”) and the adjustment of

its existing financial instruments affected

by LIBOR, whether directly or

indirectly.

LIBOR-

based originations were ceased as of June 30, 2023, and for existing LIBOR-based transactions,

the Company substituted

Secured Overnight

Financing Rate

(“SOFR”) for

LIBOR. The

Company has

completed its

transition away

from LIBOR

for

its loan and other financial instruments.

Issued and Not Yet Adopted

Improvements to Income Tax

Disclosures

December

2023,

the

FASB

issued

Accounting

Standards

Update

(ASU)

2023-09,

Income

Taxes

(Topic

740):

Improvements to Income Tax

Disclosures. This ASU pertains to

disclosures regarding effective

tax rates and cash income

taxes paid with the goal of providing stakeholders with more transparent

and relevant information. This ASU is effective for

public business entities for annual periods beginning after Dec. 15,

The Company is currently assessing the potential

impact of this

ASU on its

financial reporting and

has not yet

concluded whether the

changes will materially

affect its business

operations or consolidated financial statements.

INVESTMENT SECURITIES

The measurement of expected credit losses under the current expected credit loss (“CECL”) methodology is applicable

financial

assets

measured

amortized

cost,

including

loan

receivables

and

held-to-maturity

debt

securities.

The

accounting

for available-for-sale

debt securities

credit

losses is

presented

as an

allowance rather

than

as a

write-down.

Management does not intend to sell or believes that

it is more likely they will not be required to sell AFS

securities.

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

classified as

HTM, the

explicit guarantee

of the U.S.

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

the

Company

least

quarterly

basis.

March

and

December

all

securities held by the Company were rated investment

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 $

thousand Allowance for

credit losses (“ACL”)

as of March

31, 2024. 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 March 31, 2024 and December 31,

2023 was not required.

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

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

the

assessment

these

mitigating

factors,

management

believed

that

the

unrealized

losses

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 March 31, 2024, the Company

does not intend to sell

debt securities that are in

an unrealized loss position

and it is

more than likely not required to sell these securities before recovery

of the amortized cost basis.

maintains a

•

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

economic

forecasts

March

showed

moderate

improvements in unemployment and a slower real GDP growth.

Fannie Mae HPI forecast reflected important improvement

in national housing prices over the next four quarters.

The Company continued to adjust the HPI index effect on 1-4 Family

loan portfolio with a qualitative

factor because Florida

housing prices are performing

better than national levels.

Q-Factors

were reviewed and updated; maximum loss calculations are based on refreshed stress test and risk statuses

were updated

Our ACL

included residential

loan segment.

of March

increase

index, the forecast reduces

reserves by approximately $

basis point to

the reserve coverage ratio,

everything else being

constant. This

sensitivity analysis provides

a hypothetical result

sensitivity of the

and does not represent a change in management’s

judgement.

As of March 31, 2024, we

stress tested two qualitative factors in our commercial real

We evaluated

the impact

of a

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.

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.

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.

Commitments to

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

committed.

Standby

are

conditional

commitments

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 since

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 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.

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

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,

change in

valuation technique or

the use

of multiple

valuation techniques may

be appropriate.

In such

instances, determining

the

price

which

willing

market

participants

would

transact

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

liability,

either

directly

indirectly.

The

valuation

may

based

quoted

prices

for

similar

assets

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

the

assets

Level

assets

and

liabilities

include

financial

instruments

whose value

is determined

using pricing

models, discounted

methodologies,

or similar

techniques,

well as instruments for which determination of fair value

requires significant management judgment or estimation.

Items Measured at Fair Value

on a Recurring Basis

AFS 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

derivatives

are

measured

with

pricing

provided

STOCKHOLDERS’ EQUITY

Common Stock

In July

2021, the

Bank completed

the initial

public offering

of its

Class

A common

stock, in

which it

issued

and sold

4,600,000

shares of Class A

common stock at a

price of $

10.00

per share. The Bank

received total net proceeds

of $

40.0

million after deducting underwriting discounts and expenses.

In December 2021,

the Company acquired

all the issued

and outstanding shares

of the Class

A common stock

of the

Bank, which at the time were

the only issued and outstanding shares

of the Bank’s capital stock,

in a share exchange (the

“Reorganization”)

effected

under

the

Florida

Business

Corporation

Act.

Each

outstanding

the

Bank’s

Class

common stock,

par value

1.00

per share,

formerly held

by its

Shareholders was

converted into

and exchanged

for

one

newly

issued

the

Company’s

Class

common

stock,

par

value

1.00

per

share,

and

the

Bank

became

the

Company’s wholly owned subsidiary.

In the

Reorganization,

each

shareholder

of the

Bank

received securities

the same

class,

having

substantially

the

same designations,

rights,

powers, preferences,

qualifications,

limitations

and restrictions,

as those

that the

shareholder

held in the Bank,

and the Company’s

then current shareholders

owned the same

percentages of the

Company’s common

stock as they previously owned of the Bank’s common

stock.

During the first quarter 2024, the Company issued

52,753

shares of Class A common stock to employees as restricted

stock awards

pursuant to

the Company’s

2015 equity

incentive plan

During

the first

quarter 2023,

the Company

issued

121,627

shares of Class A

common stock to

employees and directors as

restricted stock awards pursuant

to the Company’s

2015 equity incentive plan.

During the three months ended

March 31, 2024, the Company

repurchased

7,100

shares of Class A common stock at

a weighted average price per share of $

11.15

. The aggregate purchase price for these transactions was approximately $

thousand,

including

transaction

costs.

These

repurchases

were

made

pursuant

the

Company’s

publicly

announced

repurchase program. As of March 31, 2024,

72,980

shares remained authorized for repurchase under this program. During

the three months

ended March 31,

2023, the Company

repurchased

500,000

shares of Class

common stock at

a weighted

average price

per share

of $

11.74

. The

aggregate purchase

price for

these transactions

was approximately

5.9

million,

including transaction costs.

See Note 11, Subsequent Events, for information

regarding the new share repurchase program declared in April 2024.

Shares of the Company’s Class

A common stock issued

and outstanding as of

March 31, 2024 and

December 31, 2023

were

19,650,463

and

19,575,435

, respectively.

Dividends

Declaration of dividends

by the Board

is required before

dividend payments

are made. 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

Company’s

retained

income

for

the

preceding

two

years,

defined

state

banking

regulations. However,

for any

dividend declaration,

the Company

must consider

additional factors

such as

the amount

current period net income, liquidity,

asset quality,

capital adequacy and economic conditions

at the Bank since the Bank is

the primary source

of funds to fund

dividends by the Company.

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 if they deem such payment to be an unsafe

or unsound practice.

On January

29,

2024,

the

Company

announced

that

its

Board

of Directors

approved

a cash

dividend

program.

The

quarterly dividend

for the

first quarter

of 2024

was $

0.05

per share

of Class

A common

stock, paid

on March

5, 2024,

stockholders of record as of the close of business

on February 15, 2024. Total amount paid to shareholders in dividends on

February 15,

2024 was

1.0

million.

dividends were

declared by

the Board

for the

stockholders for

the quarter

ended

March 31, 2023.

EARNINGS PER SHARE

Earnings

per

(“EPS”)

for

common

stock

calculated

using

the

two-class

method

required

for

participating

securities. Basic EPS

is calculated by

dividing net income

(loss) available to

common shareholders 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 share

holders 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.

Non-GAAP Financial Measures

This Form 10-Q

includes financial information determined by

methods other than in

accordance with generally accepted

accounting principles (“GAAP”). This financial information

includes certain operating performance measures.

Management

has included these non-GAAP measures because it believes these

measures may provide useful supplemental information

for evaluating the Company’s underlying performance trends. Further, management uses these measures in

managing and

evaluating

the

Company’s

business

and

intends

refer

them

discussions

about

our

operations

and

performance.

Operating performance measures

should be viewed in

addition to, and not

as an alternative to

or substitute for,

measures

determined in accordance with GAAP,

and are not necessarily comparable to non-GAAP measures that may

be presented

by other companies. To the extent applicable, reconciliations of these

non-GAAP measures to the most

directly comparable

GAAP

measures

can

Financial

Measures” included in this Form 10-Q.

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

evaluated

overall

Company-wide

basis.

Accordingly, all

the financial service

operations are

considered by management

to be

aggregated in one

reportable operating

segment.

Three months ended March 31, 2024 compared to the three

months ended March 31, 2023

During the

three months

ended March

31,

2024, total

interest

income

increased

$8.5

million compared

to the

same

period in

However,

this positive

trend was

offset by

a $9.3

million increase

in total

interest expense

due to

higher

weighted average deposit

costs

and borrowing costs.

Consequently, net income

decreased $1.2 million

to $4.6 million

for

the three months ended March 31, 2024 compared to the three

months ended March 31, 2023.

Net Interest Income

Net interest income

is the difference

between interest

earned on interest-earning

assets and interest

paid on interest-

bearing liabilities

and is

the primary

driver of

core earnings.

Interest income

is generated

from interest

and dividends

interest-earning

assets,

including

loans,

investment

securities

and

other

short-term

investments.

Interest

expense

incurred

from

interest

paid

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 yields earned on interest-earning assets and 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 indirect benefit of these

non-interest-bearing funding sources.

Changes

market

interest

rates

and

interest

rates

earn

interest-earning

assets

pay

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.

Our

asset liability committee

(“ALCO”) has

in place asset-liability

management techniques

to manage major

factors that

affect

net interest income and net interest margin.

Three months ended March 31, 2024 compared to the three months

ended March 31, 2023

Net interest income before the provision for

credit losses was $15.2 million for the

three months ended March 31, 2024,

decrease

$839

thousand

5.2%,

from

$16.0

million

for

the

same

period

2023.

The

decrease

was

primarily

attributable

the

$9.3

million

increase

interest

expense,

which

was

result

the

prevailing

market

interest

rate

conditions which offset the increase in interest income.

Net

interest

margin

was

2.62%

for

the

quarter

ended

March 31,

2024

and

3.22%

for

the

same

period

increases

in loan yields as well as yields on other interest-earning assets was offset by

higher deposit and borrowing costs.

Provision for Credit Losses

The provision

for credit

losses represents

a charge

to earnings

necessary to

maintain an

allowance for

credit losses

that, in

management's evaluation,

is adequate

to provide

coverage for

all expected

credit losses.

The provision

for credit

losses is impacted

by variations in

the size and

composition of our

loan and debt

securities portfolio, recent

historical and

projected future economic conditions, our internal assessment of the credit quality of the loan and debt

securities portfolios

and net charge-offs.

Q1 2024 Form 10-Q

Three months ended March 31, 2024 compared to the three months

for the

three months

Growth in

the loan

portfolio was

the primary

driver of

the increase

in the

provision expense

during the three months ended March 31, 2024.

Non-Interest Income

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 and are beneficiaries of the life

insurance policies on some of our

employees and generate income from

the increase in the cash surrender

value of these

policies.

Non-interest expense for the three

months ended March 31, 2024

increased $998 thousand or 9.8%,

compared to the

same period in 2023. The increase was

primarily driven by an increase

in other operating expenses of $578

thousand due

to $199 thousand

increase in

internal and

external audit

expense, $70

thousand increase

in miscellaneous

expense, and

$97

thousand

increase

force-placed

insurance

expense

(this

expense

will

customers).

Additionally, consulting and legal fees increased

$234 thousand due to legal

expenses

and regulatory assessment and fees

increased $209 thousand mostly due to FDIC deposit insurance

as our deposit portfolio grew.

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 expenses for

income tax purposes.

Therefore, future

decisions on the

investments we choose

will affect our

effective

tax rate.

The cash

surrender value

of bank-owned

life insurance

policies covering

key employees,

purchasing municipal

bonds, and overall levels of taxable income will be important

elements in determining our effective tax rate.

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

philosophy

the

portfolio

maximize

the

Company’s

profitability

taking

into

consideration the Company’s

risk appetite and

tolerance, manage

the asset composition

and diversification,

and maintain

adequate risk-based capital ratios.

The investment portfolio

is managed in accordance

with the Board approved

Asset and Liability

Management (“ALM”)

policy,

which

includes

investment

guidelines.

Such

policy

reviewed

least

annually

frequently

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 objective directed

the

Asset-Liability

Committee

(“ALCO”).

The

portfolio

also

can

used

modify

the

duration

the

balance

sheet.

The

allocation

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,

U.S.

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 prior to

maturity

depending on

capital market

conditions

and

expectations.

The

investment

portfolio

is regularly

reviewed by

the

Chief Financial

Officer,

Treasurer,

and the

ALCO of

the Company

to ensure

an appropriate

risk and

return profile

as well

as for adherence to the investment policy.

When evaluating AFS

debt securities under

ASC Topic

326, the Company

evaluates

whether the decline

in fair value

is attributable

to credit losses

or other

factors like interest

rate risk,

using both quantitative

and qualitative

analyses, including

company

performance

analysis,

review

credit

ratings,

remaining

payment

terms,

prepayment

speeds

and

analysis

macro-economic conditions.

Each investment is

expected to recover

its unrealized loss

position over its

holding period as

it approaches to maturity

and the Company has

the intent and ability

to hold these securities

to maturity until

recovery.

a result of this evaluation, the

Company concluded that no allowance was required on AFS

securities as of March 31, 2024.

AFS and HTM investment securities increased $28.7 million,

or 28.6% annualized, to $433.0 million at March 31, 2024

from $404.3 million at December 31, 2023. Investment

securities increased due to reinvestment of payments

received and

investment of excess

in cash

balances into high

credit quality investments

to increase the

Company’s profitability and

modify

’s

balance

sheet

according to

the

ALM policy.

As of

March 31, 2024,

investment

securities

with

Loans

Loans are the

largest category of

interest-earning assets

on the unaudited

Consolidated Balance

Sheets, and usually

provide higher yields than the

remainder of the interest

-earning assets. Higher yields

typically carry greater

inherent credit

and liquidity risks in comparison to lower yield assets. The Company manages and mitigates such risks in accordance with

the credit and ALM policies, risk tolerance and balance

sheet composition.

the

focus

which

approximately 58% of the

growth strategy since inception has

been

reflective of the market in which we operate and of our strategic

plan as approved by the Board.

Most of the

commercial real estate

exposure represents

loans to commercial

businesses secured

by owner-occupied

real estate.

The growth

experienced in

is primarily

due to

implementation of

our relationship-based

model and

the success

of our

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 reviewed

at least once a

year, and

more frequently as

needed. 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.

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, other real

estate owned (“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

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

of our customers we may

include commitments to extend

credit and standby letters

a varying

degree, such

commitments involve

elements of

credit, market,

and interest

rate risk

in excess

of the

Interest Rate Risk

(“IRR”) is inherent to

When assessing

the scope

of IRR

exposure

and

impact on

statement,

management

considers

both

economic

impacts.

Asset

price

variations,

the Company’s liquidity,

performance, and capital adequacy.

Income simulations

are used

to assess

the impact

of changing

time horizons.

These simulations

utilize both

instantaneous and

parallel changes

in the

level of

as well

non-parallel changes such as

changing slopes (flat and steepening)

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

will

change

under

rate

scenarios (parallel and non-parallel). The economic value approach focuses on a longer-term time horizon and captures all

future cash flows expected

from existing assets and

model utilizes a static

approach in that

the analysis

does not

snapshot in

inherent in

balance sheet.

Market and Interest Rate Risk Management

According to our

ALCO model, as

of March 31,

2024, we had

an asset sensitive

balance sheet both

for year one

and

year two

modeling, using

the static

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 EVE

do not include actions that management

may

undertake to manage the risks in response to anticipated changes in interest rates or customer deposit behavior. As part of

our ALM strategy and policy, management

has the ability to modify the balance sheet to either increase asset duration and

decrease liability

duration to reduce

asset sensitivity,

or to decrease

asset duration and

increase liability duration

in order

to increase asset sensitivity.

According to

our model,

as of

March

31, 2024,

our balance

sheet

is asset

sensitive

for both

year

one and

year

two

under interest

static rate

scenarios (an

increase or

decrease of

400 basis

points).

This means

rates increase,

NIM will increase and if rates decrease, the NIM will decrease.

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 in

interest rates will have a

negative impact on the EVE

and lower rates, a positive

impact. Results and analysis are presented

quarterly to the ALCO, and strategies are reviewed and refined.

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 relatively adequate funding. The

Impact of Inflation

Our

Consolidated

Financial

Statements

and

notes

have

been

prepared

accordance

with

U.S.

GAAP,

which require 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

relatively lower interest rates.

As market interest rates

rise or fall in relation

to the rates earned

on loans and investments,

the

value

these

assets

decreases

increases

respectively.

Inflation

can

also

impact

core

non-interest

expenses

associated with delivering the Company’s services.

Quantitative and Qualitative Disclosures About Market Risk

Evaluation of Disclosure Controls and Procedures

Under the

the participation of

our management, including

our President and

the effectiveness

of the

and

under

Act)

March 31,

2024.

Based on that evaluation,

management believes that, as of

the end of

the period covered by

this Form 10-Q, 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.

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 the period covered by this Form 10-Q that has

materially affected, or is reasonably likely to

materially affect, our internal control over financial

reporting.

Limitations on Effectiveness of Controls and Procedures

designing

and

evaluating

the

disclosure

controls

and

procedures,

management

recognizes

that

any

controls

and

procedures, no matter how well designed and operated, can provide only reasonable, not absolute, assurance of achieving

the desired control objectives.

In addition, the design

of disclosure controls and

procedures must reflect the

fact that there

are resource constraints and that management is required to apply

judgment in evaluating the benefits of possible controls

and procedures relative to their costs.

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

Aguilera

al.)

alleging

the

Defendants

(i) caused

the

Bank,

directors

thereof,

engage

in ultra

vires

conduct by

devising

and

approving

the

exchange

transaction

effected

July

2021

pursuant

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

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.

The 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

the

parties

December

14,

2023,

granted

the

Motion,

dismissing

the

Litigation

with

prejudice

and

rendering

final

judgment in favor

of the Defendants

(the “Order”). The Court

reserved jurisdiction to award

costs or grant

any post-judgment

relief.

On May 1, 2024, the

Plaintiffs filed in the

Thirds District Court of

Appeal for the State of

Florida (the “Appellate Court”)

an appeal, appealing the issuance of the Order and seeking a reversal of the Order.

The Plaintiffs claim the Court erred by

concluding

(i)

the

Exchange

Transaction

was

not

ultra

vires,

and

(ii)

that

the

Legacy

Shareholders

(which

includes

the

Plaintiffs) lacked direct standing.

The Company believes

that the positions

in the Appeal

are legally

and factually without

merit, and it

intends to vigorously

defend

against

the

Appeal,
