Table of Contents CAUTIONARY NOTE REGARDING FORWARD-LOOKING STATEMENTS

This report and other publicly available documents of the Company contain forward-looking statements within the meaning of the Private Securities Litigation Reform Act, including, but not limited to, management’s expectations regarding future plans, strategies and financial performance, including regulatory developments, industry and economic trends and estimates and assumptions underlying accounting policies.  Forward-looking statements are based on our current beliefs, expectations and assumptions and on information currently available and, can be identified by the use of words such as “expects,” “intends,” “believes,” “may,” “will,” “would,” “could,” “should,” “plan,” “anticipate,” “estimate,” “possible,” “likely” or the negative thereof as well as other similar words and expressions of the future. Forward-looking statements are subject to risks, uncertainties and assumptions that are difficult to predict as to timing, extent, likelihood and degree of occurrence, which could cause our actual results to differ materially from those anticipated in or by such statements. Potential risks and uncertainties include, but are not limited to, the following:

our ability to execute our growth strategy;
negative economic conditions that adversely affect the economy, real estate values, the job market and other factors nationally and in our market area, in each case that may affect our liquidity and the performance of our loan portfolio;
--- ---
risks with respect to our ability to successfully expand and integrate businesses and operations that we acquire, as well our ability to identify and complete future mergers or acquisitions;
--- ---
the financial success and viability of the borrowers of our commercial loans;
--- ---
changes in U.S. monetary policy, the level and volatility of interest rates, the capital markets and other market conditions that may affect, among other things, our liquidity and the value of our assets and liabilities;
--- ---
competitive pressures from other financial service businesses and from nontraditional financial technology (“FinTech”) companies;
--- ---
any negative perception of our reputation or financial strength;
--- ---
our ability to raise additional capital on acceptable terms when needed;
--- ---
our ability to raise cost-effective funding to support business plans when needed:
--- ---
our ability to use technology to provide products and services that will satisfy customer demands and create efficiencies in operations;
--- ---
adverse effects on our information technology systems resulting from system failures, human error or cyberattacks;
--- ---
adverse effects of failures by our vendors to provide agreed upon services in the manner and at the cost agreed, particularly our information technology vendors and those vendors performing a service on the Company’s behalf;
--- ---
the impact of any claims or legal actions, including any effect on our reputation;
--- ---
losses incurred in connection with repurchases and indemnification payments related to mortgages;
--- ---
the soundness of other financial institutions and other counter-party risk;
--- ---
changes in accounting standards, rules and interpretations and the related impact on our financial statements;
--- ---
our ability to receive dividends from our subsidiaries;
--- ---
a decrease in our regulatory capital ratios or negative changes in our capital position;
--- ---
adverse federal or state tax assessments, or changes in tax laws or policies;
--- ---
risks associated with actual or potential litigation or investigations by customers, regulatory agencies or others;
--- ---
legislative or regulatory changes, particularly changes in regulation of financial services companies;
--- ---
increased costs of compliance, heightened regulatory capital requirements and other risks associated with changes in regulation and the current regulatory environment;
--- ---
risks associated with complex and changing regulatory environments, including, among others, with respect to data privacy, artificial intelligence, information security, climate change or other environmental, social and governance matters, and labor matters, relating to our operations;
--- ---
the adverse effects of events beyond our control that may have a destabilizing effect on financial markets and the economy, such as epidemics and pandemics, war or terrorist activities, such as the war in Ukraine, the Middle East conflict, and the conflict between China and Taiwan, essential utility outages, deterioration in the global economy, instability in the credit markets, disruptions in our customers’ supply chains or disruption in transportation;
--- ---
changes in trade policy and any related tariffs; and
--- ---
each of the factors and risks under the heading “Risk Factors” in our 2023 Annual Report on Form 10-K and in subsequent filings we make with the SEC.
--- ---

Because the Company’s ability to predict results or the actual effect of future plans or strategies is inherently uncertain, there can be no assurances that future actual results will correspond to any forward-looking statements and you should not rely on any forward-looking statements.  Additionally, all statements in this Form 10-Q, including forward-looking statements, speak only as of the date they are made, and the Company undertakes no obligation to update any statement in light of new information or future events, except as required by applicable law.

Notes to Consolidated Financial Statements

(Dollar amounts in thousands, except per share data, unaudited)

Note 1 – Basis of Presentation and Changes in Significant Accounting Policies

The accounting policies followed in the preparation of the interim consolidated financial statements are consistent with those used in the preparation of the annual financial information.  The interim consolidated financial statements reflect all normal and recurring adjustments that are necessary, in the opinion of management, for a fair statement of results for the interim period presented.  Results for the period ended March 31, 2024 are not necessarily indicative of the results that may be expected for the year ending December 31, 2024.  These interim consolidated financial statements and accompanying notes are unaudited and should be read in conjunction with the audited financial statements and notes included in Old Second Bancorp, Inc.’s (the “Company”) annual report on Form 10-K for the year ended December 31, 2023.  Unless otherwise indicated, dollar amounts in the tables contained in the notes to the consolidated financial statements are in thousands.  Certain items in prior periods have been reclassified to conform to the current presentation.

The Company’s consolidated financial statements are prepared in accordance with United States generally accepted accounting principles (“GAAP”) and follow general practices within the banking industry.  Application of these principles requires management to make estimates, assumptions, and judgments that affect the amounts reported in the consolidated financial statements and accompanying notes.  These estimates, assumptions, and judgments are based on information available as of the date of the consolidated financial statements.  Future changes in information may affect these estimates, assumptions, and judgments, which, in turn, may affect amounts reported in the consolidated financial statements.

Recent Accounting Pronouncements

The following is a summary of recent accounting pronouncements that have impacted or could potentially affect the Company**:**

ASU 2023-06 – On October 9, 2023, the FASB issued ASU 2023-06 “Disclosure Improvements: Codification Amendments in Response to the SEC’s Disclosure Update and Simplification Initiative.” The amendments in the ASU modify the disclosure or presentation requirements of a variety of Topics in the Codification. Certain of the amendments represent clarifications to, or technical corrections of, the current requirements. Each amendment in the ASU will only become effective if the SEC removes the related disclosure or presentation requirement from its existing regulations by June 30, 2027. The amendments in this ASU are not expected to have a material impact on the financial statements of the Company.

ASU 2023-09 – On December 14, 2023, the FASB issued ASU 2023-09 “Income Taxes (Topic 740): Improvements to Income Tax Disclosures”. The amendments require that public business entities on an annual basis (1) disclose specific categories in the rate reconciliation, and (2) provide additional information for reconciling items that meet a quantitative threshold (if the effect of those reconciling items is equal to or greater than 5 percent of the amount computed by multiplying pretax income (or loss) by the applicable statutory income tax rate). The amendments require that all entities disclose on an annual basis the following information about income taxes paid: (1) The amount of income taxes paid (net of refunds received) disaggregated by federal (national), state, and foreign taxes, and (2) The amount of income taxes paid (net of refunds received) disaggregated by individual jurisdictions in which income taxes paid (net of refunds received) is equal to or greater than 5 percent of total income taxes paid (net of refunds received). The amendments also require that all entities disclose the following information: (1) Income (or loss) from continuing operations before income tax expense (or benefit) disaggregated between domestic and foreign, and (2) Income tax expense (or benefit) from continuing operations disaggregated by federal (national), state, and foreign. The ASU is effective for public business entities for annual periods beginning after December 15, 2024.  Early adoption is permitted for annual financial statements that have not yet been issued or made available for issuance. The amendments should be applied on a prospective basis. Retrospective application is permitted.  The Company will adopt this ASU for the reporting period beginning January 1, 2025, and does not expect the amendments to have a material impact to the financial statements of the Company.

ASU 2024-01 – On March 21, 2024, the FASB issued ASU 2024-01 “Compensation - Stock Compensation (Topic 718) - Scope Application of Profits Interest and Similar Awards” which clarifies how an entity determines whether a profits interest or similar award is within the scope of Topic 718, or is not a share-based payment arrangement and therefore within the scope of other guidance. ASU 2024-01 provides an illustrative example with multiple fact patterns and also amends certain language in the “Scope” and “Scope Exceptions” sections of Topic 718 to improve its clarity and operability without changing the guidance. Entities can apply the amendments either retrospectively to all prior periods presented in the financial statements or prospectively to profits interest and similar awards granted or modified on or after the date of adoption. If prospective application is elected, an entity must disclose the nature of and reason for the change in accounting principle. ASU 2024-01 is effective January 1, 2025, including interim periods, and is not expected to have a material impact the financial statements of the Company.

ASU 2024-02 – On March 29, 2024, the FASB issued ASU 2024-02 “Codification Improvements” amends the Codification to remove references to various concept statements and impacts a variety of topics in the Codification. The amendments apply to all reporting entities within the scope of the affected accounting guidance, but in most instances the references removed are extraneous and not required to understand or apply the guidance. Generally, the amendments in ASU 2024-02 are not intended to result in significant accounting changes for most entities. ASU 2024-02 is effective January 1, 2025 and is not expected to have a material impact the financial statements of the Company.

Change in Significant Accounting Policies

Significant accounting policies are presented in Note 1 to the consolidated financial statements included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2023.  These policies, along with the disclosures presented in the other financial statement notes and in this discussion, provide information on how significant assets and liabilities are valued in the consolidated financial statements and how those values are determined.  During the first quarter of 2024, the Company had no changes to significant accounting policies or estimates.

Subsequent Events

On April 16, 2024, our Board of Directors declared a cash dividend of $0.05 per share of common stock payable on May 6, 2024, to stockholders of record as of April 26, 2024; dividends of $2.2 million were paid to stockholders on May 6, 2024.

Our investment portfolio serves the liquidity needs and income objectives of the Company.  While the portfolio serves as an important component of the overall liquidity management at the Bank, portions of the portfolio also serve as income producing assets.  The size and composition of the portfolio reflects liquidity needs, loan demand and interest income objectives.  Portfolio size and composition will be adjusted from time to time.  While a significant portion of the portfolio consists of readily marketable securities to address liquidity, other parts of the portfolio may reflect funds invested pending future loan demand or to maximize interest income without undue interest rate risk.

Investments are comprised of debt securities and non-marketable equity investments.  Securities available-for-sale are carried at fair value.  Unrealized gains and losses, net of tax, on securities available-for-sale are reported as a separate component of equity.  This balance sheet component changes as interest rates and market conditions change.  Unrealized gains and losses are not included in the calculation of regulatory capital.

Federal Home Loan Bank of Chicago (“FHLBC”) and Federal Reserve Bank of Chicago (“FRBC”) stock are considered nonmarketable equity investments.  FHLBC stock was recorded at $13.6 million at March 31, 2024 and $18.5 million at December 31, 2023.  FRBC stock was recorded at $14.9 million at March 31, 2024 and December 31, 2023.

The following tables summarize the amortized cost and fair value of the securities portfolio at March 31, 2024, and December 31, 2023, and the corresponding amounts of gross unrealized gains and losses:

Each quarter, we perform an analysis to determine if any of the unrealized losses on securities available-for-sale are comprised of credit losses as compared to unrealized losses due to market interest rate adjustments.  Our assessment includes a review of the unrealized loss for each security issuance held; the financial condition and near-term prospects of the issuer, including external credit ratings and recent downgrades; and our ability and intent to hold the security for a period of time sufficient for a recovery in value. We also consider the extent to which the securities are issued by the federal government or its agencies, and any guarantee of issued amounts by those agencies.  The portfolio continues to consist of a mix of fixed and floating-rate, high quality securities, largely rated AA (or better), displaying an overall effective duration of approximately 3.0 years.  No credit losses were determined to be present as of March 31, 2024, as there was no credit quality deterioration noted.  Therefore, no provision for credit losses on securities was recognized for the first quarter of 2024.

It is the policy of the Company to review each prospective credit prior to making a loan in order to determine if an adequate level of security or collateral has been obtained.  The type of collateral, when required, will vary from liquid assets to real estate.  The Company seeks to assure access to collateral, in the event of borrower default, through adherence to lending laws, the Company’s lending standards and credit monitoring procedures.  Although the Bank makes loans primarily within its market area, there are no significant concentrations of loans where the customers’ ability to honor loan terms is dependent upon a single economic sector.  The real estate related categories listed above represent 68.7% and 68.8% of the portfolio at March 31, 2024, and December 31, 2023, respectively, and include a mix of owner occupied and non-owner occupied commercial real estate, residential, construction and multifamily loans.

At March 31, 2024, our allowance for credit losses (“ACL”) on loans totaled $44.1 million, and our ACL on unfunded commitments, included in other liabilities, totaled $2.7 million.  During the first three months of 2024, we recorded net provision expense of $3.5 million based on historical loss rate updates driven by higher charge offs in commercial real estate-investor, downward risk rating migration, and our assessment of estimated future credit losses. The ACL on loans excludes $2.7 million, $2.7 million and $3.8 million of allowance for unfunded commitments as of March 31, 2024, December 31, 2023, and March 31, 2023, respectively, recorded within other liabilities.

Generally, the Bank considers a loan to be collateral dependent when, based on current information and events, it is probable that foreclosure could be initiated. Additionally, the Bank will review all loans meeting the criteria for individual analysis, to determine if repayment or satisfaction of the loan is expected through the sale of collateral. This will generally be the case for credits with high loan-to-values. Exceptions to this policy would include loans with guarantors or sponsors that have the means and willingness to support the obligation. Non-accruing loans with an outstanding balance of $500,000 or more are assessed on an individual loan level basis. When a financial asset is deemed collateral-dependent, the level of credit loss is measured by the difference between amortized cost of the financial asset and the fair value of collateral adjusted for estimated cost to sell. The Company had $59.3 million and $63.1 million of collateral dependent loans secured by real estate or business assets as of March 31, 2024, and December 31, 2023, respectively.

The following tables present the collateral dependent loans and the related ACL allocated by segment of loans as of March 31, 2024 and December 31, 2023:

Credit Quality Indicators

The Company categorizes loans into credit risk categories based on current financial information, overall debt service coverage, comparison to industry averages, historical payment experience, and current economic trends.  This analysis includes loans with outstanding balances or commitments greater than $50,000 and excludes homogeneous loans such as home equity lines of credit and residential mortgages.  Loans with a classified risk rating are reviewed quarterly regardless of size or loan type.  The Company uses the following definitions for classified risk ratings:

**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 at some future date.

Substandard. Loans classified as substandard are inadequately protected by the current net worth and paying capacity of the obligor 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 Bank will sustain some loss if the deficiencies are not corrected.  The substandard credit quality indicator includes both potential problem loans that are currently performing and nonperforming loans.

Doubtful.  Loans classified as doubtful have all the weaknesses inherent in those classified as 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.

Credits that are not covered by the definitions above are pass credits, which are not considered to be adversely rated.

Note 6 – Borrowings

The following table is a summary of borrowings as of March 31, 2024 and December 31, 2023.  Junior subordinated debentures are discussed in more detail in Note 7.

**** March 31, 2024 December 31, 2023 ****

Subordinated debentures 59,403 59,382
Total borrowings $ 338,722 $ 516,625

^1^See Note 7: Junior Subordinated Debentures.

The Company enters into deposit sweep transactions where the transaction amounts are secured by pledged securities.  These transactions consistently mature overnight from the transaction date and are governed by sweep repurchase agreements.  All sweep repurchase agreements are treated as financings secured by U.S. government agencies and collateralized mortgage-backed securities, and had a carrying amount of $33.5 million at March 31, 2024, and $26.5 million at December 31, 2023.  The fair value of the pledged collateral was $45.2 million at March 31, 2024, and $45.7 million at December 31, 2023.  At March 31, 2024, there were no customers with secured balances exceeding 10% of stockholders’ equity.

The Company’s borrowings at the FHLBC require the Bank to be a member and invest in the stock of the FHLBC.  Total borrowings are generally limited to the lower of 35% of total assets or 60% of the book value of certain mortgage loans.  As of March 31, 2024, the Bank had $220.0 million in short-term advances outstanding under the FHLBC, and $405.0 million in short-term advances as of December 31, 2023. FHLBC stock held at March 31, 2024 was valued at $13.6 million, and any potential FHLBC advances were collateralized by loans and securities with a principal balance of $1.44 billion, which carried a FHLBC-calculated combined collateral value of $998.9 billion.  The Company had excess collateral of $778.9 million available to secure borrowings at March 31, 2024.

In the second quarter of 2021, we issued $60.0 million in aggregate principal amount of our 3.50% Fixed-to-Floating Rate Subordinated Notes due April 15, 2031 (the “Notes”). The Company used the net proceeds from the offering for general corporate purposes.  The Notes bear interest at a fixed annual rate of 3.50%, from and including the date of issuance to but excluding April 15, 2026, payable semi-annually in arrears.  From and including April 15, 2026 to, but excluding the maturity date or early redemption date, the interest rate will reset quarterly to an interest rate per annum equal to three-month Term Secured Overnight Financing Rate (“SOFR”) (as defined by the Note) plus 273 basis points, payable quarterly in arrears. As of March 31, 2024 and December 31, 2023, we had $59.4 million of subordinated debentures outstanding, net of deferred issuance cost.

The Company issued senior notes in December 2016 with a ten-year maturity, and terms included interest payable semiannually at 5.75% for five years.  Beginning December 31, 2021, the senior debt began to pay interest at a floating rate, with interest payable quarterly at three month LIBOR plus 385 basis points. The notes were redeemable, in whole or in part, at the option of the Company, beginning with the interest payment date on December 31, 2021, and on any floating rate interest payment date thereafter, at a redemption price equal to 100% of the principal amount of the notes plus accrued and unpaid interest.  On June 30, 2023, we redeemed all of the $45.0 million senior notes, at which point the interest rate was 9.39%.  Upon redemption, the related deferred debt issuance costs of $362,000 was also recorded as interest expense, resulting in an effective cost of this debt issuance of 12.85% for the second quarter of 2023.

On February 24, 2020, the Company originated a $20.0 million three-year term note with a correspondent bank. The term note was issued at one-month LIBOR plus 175 basis points, and required principal payments quarterly and interest payments monthly.  This note was included within Notes payable and other borrowings on the Consolidated Balance Sheets, and the remaining $9.0 million balance of the note was paid off on February 24, 2023.  The Company also has an undrawn line of credit of $30.0 million with a correspondent bank to be used for short-term funding needs; advances under this line can be outstanding up to 360 days from the date of issuance.  This line of credit has not been utilized since early 2019.

Note 7 – Junior Subordinated Debentures

The Company issued $25.0 million of cumulative trust preferred securities through a private placement completed by an unconsolidated subsidiary, Old Second Capital Trust II, in April 2007.  These trust preferred securities mature in 30 years, but subject to regulatory approval, can be called in whole or in part on a quarterly basis commencing June 15, 2017.  The quarterly cash distributions on the securities were fixed at 6.77% through June 15, 2017, and now have a floating rate of 150 basis points over three-month SOFR.  Upon conversion to a floating rate, a cash flow hedge was initiated which resulted in the total interest rate paid on the debt of 4.37% and 4.39% for the quarters ended March 31, 2024 and March 31, 2023, respectively.  The Company issued a $25.8 million subordinated debenture to Old Second Capital Trust II in return for the aggregate net proceeds of this trust preferred offering.  The interest rate and payment frequency on the debenture are equivalent to the cash distribution basis on the trust preferred securities.

The junior subordinated debentures issued by the Company are disclosed on the Consolidated Balance Sheets, and the related interest expense for each issuance is included in the Consolidated Statements of Income.  As of March 31, 2024 and December 31, 2023, the remaining unamortized debt issuance costs related to the junior subordinated debentures were less than $1,000 and are included as a reduction to the balance of the junior subordinated debentures on the Consolidated Balance Sheets.  The remaining deferred issuance costs on the junior subordinated debentures related to the issuance of Old Second Capital Trust II will be amortized to interest expense over the remainder of the 30-year term of the notes and are included in the Consolidated Statements of Income.

Note 8 – Equity Compensation Plans

Stock-based awards are outstanding under the Company’s 2019 Equity Incentive Plan, as amended and restated (the “2019 Plan”).  The 2019 Plan was originally approved at the May 2019 annual stockholders’ meeting and authorized 600,000 shares, and at the May 2021 annual stockholders’ meeting, the Company obtained stockholder approval to increase the number of shares of common stock authorized for issuance under the 2019 Plan by 1,200,000 shares, from 600,000 shares to 1,800,000 shares.  Following the approval of the 2019 Plan, no further awards will be granted under any other prior plan.

The 2019 Plan authorizes the granting of qualified stock options, non-qualified stock options, restricted stock, restricted stock units, and stock appreciation rights (“SARs”).  Awards may be granted to selected directors, officers, employees or eligible service providers under the 2019 Plan at the discretion of the Compensation Committee of the Company’s Board of Directors.  As of March 31, 2024, 712,201 shares remained available for issuance under the 2019 Plan.  The Company has granted only restricted stock units under the 2019 Equity Plan.

Generally, restricted stock units granted under the 2019 Plan vest three years from the grant date, but the Compensation Committee of the Company’s Board of Directors has discretionary authority to change the terms of particular awards including the vesting schedule.

Under the 2019 Plan, unless otherwise provided in an award agreement, upon the occurrence of a change in control, all equity awards then held by the participant will become fully exercisable immediately if, and all stock awards and cash incentive awards will become fully earned and vested immediately if, (i) the 2019 Plan is not an obligation of the successor entity following a change in control or (ii) the 2019 Plan is an obligation of the successor entity following a change in control and the participant incurs a termination of service without cause or for good reason following the change in control.  Notwithstanding the immediately preceding sentence, if the vesting of an award is conditioned upon the achievement of performance measures, then such vesting will generally be subject to the following: if, at the time of the change in control, the performance measures are less than 50% attained (pro rata based upon the time of the period through the change in control), the award will become vested and exercisable on a fractional basis with the numerator being equal to the percentage of attainment and the denominator being 50%; and if, at the time of the change in control, the performance measures are at least 50% attained (pro rata based upon the time of the period through the change in control), the award will become fully earned and vested immediately upon the change in control.

Awards of restricted stock under the 2019 Plan generally entitle holders to voting and dividend rights upon grant and are subject to forfeiture until certain restrictions have lapsed including employment for a specific period.  Awards of restricted stock units under the 2019 Plan are also subject to forfeiture until certain restrictions have lapsed including employment for a specific period, but do not entitle holders to voting rights until the restricted period ends and shares are transferred in connection with the units.

Note 10Regulatory & Capital Matters

The Bank is subject to the risk-based capital regulatory guidelines, which include the methodology for calculating the risk-weighted Bank assets, developed by the Office of the Comptroller of the Currency (the “OCC”) and the other bank regulatory agencies.  In connection with the current risk-based capital regulatory guidelines, the Bank’s Board of Directors has established an internal guideline requiring the Bank to maintain a Tier 1 leverage capital ratio at or above eight percent (8%) and a total risk-based capital ratio at or above twelve percent (12%).  At March 31, 2024, the Bank exceeded those thresholds.

At March 31, 2024, the Bank’s Tier 1 capital leverage ratio was 10.89%, an increase of 48 basis points from December 31, 2023, and is above the 8.00% objective.  The Bank’s total capital ratio was 14.03%, an increase of 79 basis points from December 31, 2023, and also above the objective of 12.00%.

Bank holding companies are generally required to maintain minimum levels of capital in accordance with capital guidelines implemented by the Board of Governors of the Federal Reserve System.  The general bank and holding company capital adequacy guidelines are shown in the accompanying table, as are the capital ratios of the Company and the Bank, as of March 31, 2024 and December 31, 2023.

The Basel III Rules are applicable to all banking organizations that are subject to minimum capital requirements, including federal and state banks and savings and loan associations, as well as to bank and savings and loan holding companies, other than “small bank holding companies,” which are generally holding companies with consolidated assets of less than $3.0 billion.  A detailed discussion of the Basel III Rules is included in Part I, Item 1 of the Company’s Form 10-K for the year ended December 31, 2023, under the heading “Supervision and Regulation.”

At March 31, 2024 and December 31, 2023, the Company, on a consolidated basis, exceeded the minimum thresholds to be considered “well capitalized” under current regulatory defined capital ratios.

^1^Amounts are shown inclusive of a capital conservation buffer of 2.50%.

^2^ The prompt corrective action provisions are only applicable at the Bank level. The Bank exceeded the general minimum regulatory requirements to be considered “well capitalized.”

As part of its response to the impact of the COVID-19 pandemic, in the first quarter of 2020, U.S. federal regulatory authorities issued an interim final rule that provided banking organizations that adopted the Current Expected Credit Losses (“CECL”) methodology during the 2020 calendar year with the option to delay for two years the estimated impact of CECL on regulatory capital relative to regulatory capital determined under the prior incurred loss methodology, followed by a three-year transition period to phase out the aggregate amount of the capital benefit provided during the initial two-year delay (i.e., a five-year transition in total). In connection with our adoption of CECL on January 1, 2020, we elected to utilize the five-year CECL transition.  As of March 31, 2024, the capital measures of the Company exclude $951,000, which is the modified CECL transition adjustment.

Dividend Restrictions

In addition to the above requirements, banking regulations and capital guidelines generally limit the amount of dividends that may be paid by a bank without prior regulatory approval.  Under these regulations, the amount of dividends that may be paid in any calendar year is limited to the current year’s profits, combined with the retained profit of the previous two years, subject to the capital requirements described above.  As of March 31, 2024, the Bank had capacity to pay dividends of $93.7 million to the Company without prior regulatory approval.  Pursuant to the Basel III rules, the Bank must keep a capital conservation buffer of 2.50% above the regulatory minimum capital requirements, which must consist entirely of Common Equity Tier 1 capital in order to avoid additional limitations on capital distributions and certain other payments.

Note 11Fair Value Measurements

Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date.  The fair value hierarchy established by the Company also requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value.  Three levels of inputs that may be used to measure fair value are:

Level 1:  Quoted prices (unadjusted) for identical assets or liabilities in active markets that the Company has the ability to access as of the measurement date.

Level 2:  Significant observable inputs other than Level 1 prices, such as quoted prices for similar assets or liabilities, quoted prices in markets that are not active, and other inputs that are observable or can be corroborated by observable market data.

Level 3:  Significant unobservable inputs that reflect a company’s own view about the assumptions that market participants would use in pricing an asset or liability.

There were no transfers between levels at March 31, 2024, however the Company reclassified one states and political subdivisions security to an asset-backed security in all periods presented. During the three-month period ended March 31, 2023, $14.9 million of asset-backed securities and $6.8 million of collateralized mortgage obligations were transferred to Level 2 from Level 3.

The majority of securities available-for-sale are valued by external pricing services or dealer market participants and are classified in Level 2 of the fair value hierarchy.  Both market and income valuation approaches are utilized.  Quarterly, the Company evaluates the methodologies used by the external pricing services or dealer market participants to develop the fair values to determine whether the results of the valuations are representative of an exit price in the Company’s principal markets and an appropriate representation of fair value.  The Company uses the following methods and significant assumptions to estimate fair value:

Government-sponsored agency debt securities are primarily priced using available market information through processes such as benchmark spreads, market valuations of like securities, like securities groupings and matrix pricing.
Other government-sponsored agency securities, Mortgage Backed Securities (“MBS”) and some of the actively traded real estate mortgage investment conduits and collateralized mortgage obligations are priced using available market information including benchmark yields, prepayment speeds, spreads, volatility of similar securities and trade date.
--- ---
State and political subdivisions are largely grouped by characteristics (e.g., geographical data and source of revenue in trade dissemination systems).  Because some securities are not traded daily and due to other grouping limitations, active market quotes are often obtained using benchmarking for like securities.
--- ---
Auction rate securities are priced using market spreads, cash flows, prepayment speeds, and loss analytics.  Therefore, the valuations of auction rate asset-backed securities are considered Level 2 valuations.
--- ---
Asset-backed collateralized loan obligations were priced using data from a pricing matrix supported by our bond accounting service provider and are therefore considered Level 2 valuations.
--- ---
Annually every security holding is priced by a pricing service independent of the regular and recurring pricing services used.  The independent service provides a measurement to indicate if the price assigned by the regular service is within or outside of a reasonable range.  Management reviews this report and applies judgment in adjusting calculations at year end related to securities pricing.

Residential mortgage loans available for sale in the secondary market are carried at fair market value.  The fair value of loans held-for-sale is determined using quoted secondary market prices.
Lending related commitments to fund certain residential mortgage loans, e.g., residential mortgage loans with locked interest rates to be sold in the secondary market and forward commitments for the future delivery of mortgage loans to third party investors, as well as forward commitments for future delivery of MBS, are considered derivatives.  Fair values are estimated based on observable changes in mortgage interest rates including prices for MBS from the date of the commitment and do not typically involve significant judgments by management.
--- ---
The fair value of mortgage servicing rights is based on a valuation model that calculates the present value of estimated net servicing income.  The valuation model incorporates assumptions that market participants would use in estimating future net servicing income to derive the resultant value.  The Company is able to compare the valuation model inputs, such as the discount rate, prepayment speeds, weighted average delinquency and foreclosure/bankruptcy rates to widely available published industry data for reasonableness.
--- ---
Interest rate swap positions, both assets and liabilities, are based on valuation pricing models using an income approach reflecting readily observable market parameters such as interest rate yield curves.
--- ---
The fair value of individually evaluated loans with specific allocations of the allowance for credit losses is essentially based on recent real estate appraisals or the fair value of the collateralized asset.  These appraisals may utilize a single valuation approach or a combination of approaches including comparable sales and the income approach.  Adjustments are made in the appraisal process by the appraisers to reflect differences between the available comparable sales and income data.  Such adjustments are usually significant and typically result in a Level 3 classification of the inputs for determining fair value.
--- ---
Nonrecurring adjustments to certain commercial and residential real estate properties classified as other real estate owned (“OREO”) are measured at fair value, less costs to sell.  Fair values are based on third party appraisals of the property, resulting in a Level 3 classification, or an executed pending sales contract.  In cases where the carrying amount exceeds the fair value, less costs to sell, a valuation loss is recognized.

Assets and Liabilities Measured at Fair Value on a Nonrecurring Basis:

The Company may be required, from time to time, to measure certain other assets at fair value on a nonrecurring basis in accordance with GAAP.  These assets consist of individually evaluated loans and OREO.  For assets measured at fair value on a nonrecurring basis at March 31, 2024 and December 31, 2023, respectively, the following tables provide the level of valuation assumptions used to determine each valuation and the carrying value of the related assets:

March 31, 2024
**** Level 1 **** Level 2 **** Level 3 **** Total
Individually evaluated loans^1^ $ - $ - $ 53,182 $ 53,182
Other real estate owned, net^2^ - - 5,123 5,123
Total $ - $ - $ 58,305 $ 58,305

^1^ Represents carrying value and related write-downs of loans for which adjustments are substantially based on the appraised value of collateral for collateral-dependent loans, which had a carrying amount of $59.3 million and a valuation allowance of $6.2 million resulting in a decrease of specific allocations within the allowance for credit losses on loans of $4.9 million for the three months ended March 31, 2024.

^2^ OREO is measured at fair value, less costs to sell, and had a net carrying amount of $5.1 million at March 31, 2024, which is made up of the outstanding balance of $5.2 million, net of a valuation allowance of $118,000.

December 31, 2023
Level 1 **** Level 2 **** Level 3 **** Total
Individually evaluated loans^1^ $ - $ - $ 66,180 $ 66,180
Other real estate owned, net^2^ - - 5,123 5,123
Total $ - $ - $ 71,303 $ 71,303

^1^ Represents carrying value and related write-downs of loans for which adjustments are substantially based on the appraised value of collateral for collateral-dependent loans, which had a carrying amount of $77.3 million and a valuation allowance of $11.1 million resulting in a decrease of specific allocations within the allowance for credit losses on loans of $6.5 million for the year December 31, 2023.

^2^ OREO is measured at fair value, less costs to sell, and had a net carrying amount of $5.1 million at December 31, 2023, which is made up of the outstanding balance of $5.2 million, net of a valuation allowance of $118,000 .

The Company has estimated the fair values of these assets based primarily on Level 3 inputs.  OREO and individually evaluated loans are generally valued using the fair value of collateral provided by third party appraisals.  These valuations include assumptions related to cash flow projections, discount rates, and recent comparable sales.  The numerical ranges of unobservable inputs for these valuation assumptions are not meaningful.

Note 12 – Fair Values of Financial Instruments

The estimated fair values approximate carrying amount for all items except those described in the following table.  Securities available-for-sale fair values are based upon market prices or dealer quotes, and if no such information is available, on the rate and term of the security.  The carrying value of FHLBC stock approximates fair value as the stock is nonmarketable and can only be sold to the FHLBC or another member institution at par. At March 31, 2024 and December 31, 2023, the fair values of loans are estimated on an exit price basis incorporating discounts for credit, liquidity and marketability factors.  The fair value of time deposits was estimated using discounted future cash flows at current rates offered for deposits of similar remaining maturities.  The fair values of borrowings were estimated based on interest rates available to the Company for debt with similar terms and remaining maturities.  The fair value of off balance sheet volume was not considered material.

Note 13 – Derivatives, Hedging Activities and Financial Instruments with Off-Balance Sheet Risk

Risk Management Objective of Using Derivatives

The Company is exposed to certain risk arising from both its business operations and economic conditions.  The Company principally manages its exposures to a wide variety of business and operational risks through management of its core business activities. The Company manages economic risks, including interest rate, liquidity, and credit risk primarily by managing the amount, sources, and duration of its assets and liabilities and the use of derivative financial instruments.  Specifically, the Company enters into derivative financial instruments to manage exposures that arise from business activities that result in the receipt or payment of future known and uncertain cash amounts, the value of which are determined by interest rates.  The Company’s derivative financial instruments are used to manage differences in the amount, timing, and duration of the Company’s known or expected cash receipts and its known or expected cash payments principally related to the Company’s loan portfolio.

Cash Flow Hedges of Interest Rate Risk

The Company’s objectives in using interest rate derivatives are to add stability to interest income and expense and to manage its exposure to interest rate movements. To accomplish this objective, the Company primarily uses interest rate swaps as part of its interest rate risk management strategy. The aggregate fair value of the swaps is recorded in other assets or other liabilities with changes in fair value recorded in other comprehensive income, net of tax. The amount included in other comprehensive income would be reclassified to current earnings should all or a portion of the hedge no longer be considered effective. For derivatives designated and that qualify as cash flow hedges of interest rate risk, the gain or loss on the derivative is recorded in accumulated other comprehensive income and subsequently reclassified into interest income or interest expense in the same period(s) during which the hedged transaction affects earnings. Amounts reported in accumulated other comprehensive income related to derivatives will be reclassified to interest income or expense as interest payments are received on the variable rate loan pools or paid on the Company’s fixed-rate borrowings.

Interest rate swaps with notional amounts totaling $300.0 million as of March 31, 2024, and December 31, 2023, were designated as cash flow hedges of certain variable rate commercial and commercial real estate loan pools. Each of these hedges were executed to pay variable and receive fixed rate cash flows. Each of these hedges was determined to be effective during all periods presented and the Company expects the hedges to remain effective during the remaining terms of the swaps.

An interest rate swap with a notional amount of $25.8 million as of March 31, 2024 and December 31, 2023, is designated as a cash flow hedge of junior subordinated debentures and was executed to pay fixed and receive variable rate cash flows. The hedge was determined to be effective during all periods presented and the Company expects the hedge to remain effective during the remaining terms of the swap.

During the next twelve months, the Company estimates that an additional $5.5 million will be reclassified as an increase to interest income and an additional $609,000 will be reclassified as an increase to interest expense.

Non-designated Hedges

Derivatives not designated as hedges are not speculative and result from a service the Company provides to certain customers. The Company executes interest rate swaps with commercial banking customers to facilitate their respective risk management strategies. The notional amounts of interest rate swaps with its loan customers as of March 31, 2024 and December 31, 2023 were $107.0 million and $104.8 million, respectively. Those interest rate swaps are simultaneously hedged by offsetting derivatives that the Company executes with a third party, such that the Company minimizes its net risk exposure resulting from such transactions. As the interest rate derivatives associated with this program do not meet the strict hedge accounting requirements, changes in the fair value of both the customer derivatives and the offsetting derivatives are recognized directly in earnings.

At March 31, 2024 and December 31, 2023, the Company had $6.6 million and $7.3 million of cash collateral pledged with two correspondent financial institutions, respectively. The Company held $5.7 million and $4.1 million of cash pledged from one correspondent financial institution to support the interest rate swap activity during the periods presented, respectively. No investment securities were required to be pledged to any correspondent financial institution during 2024 through March 31, 2024, or during 2023. The Company offsets derivative assets and liabilities that are subject to a master netting arrangement.

The Company also grants mortgage loan interest rate lock commitments to borrowers, subject to normal loan underwriting standards. The interest rate risk associated with these loan interest rate lock commitments is managed with contracts for future deliveries of loans as well as selling forward mortgage-backed securities contracts. Loan interest rate lock commitments generally have 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 drawn upon, the total commitment amounts do not necessarily represent future cash requirements. The notional amount of these commitments at March 31, 2024 and December 31, 2023 was $9.5 million and $8.4 million, respectively. Commitments to originate residential mortgage loans held-for-sale and forward commitments to sell residential mortgage loans or forward MBS contracts are considered derivative instruments and changes in the fair value are recorded to mortgage banking revenue. Fair values are estimated based on observable changes in mortgage interest rates including mortgage-backed securities prices from the date of the commitment.

Disclosure of the Effect of Fair Value and Cash Flow Hedge Accounting

The fair value and cash flow hedge accounting related to derivatives covered under ASC Subtopic 815-20 impacted Accumulated Other Comprehensive Income (“AOCI”) and the Income Statement.  The loss recognized in AOCI on derivatives totaled $2.1 million as of March 31, 2024, and $3.1 million as of March 31, 2023.  The amount of the loss reclassified from AOCI to net interest income on the income statement was $1.6 million for the three months ended March 31, 2024 and $1.0 million for the three months ended March 31, 2023.

Credit-risk-related Contingent Features

For derivative transactions involving counterparties who are lending customers of the Company, the derivative credit exposure is managed through the normal credit review and monitoring process, which may include collateralization, financial covenants and/or financial guarantees of affiliated parties.  Agreements with such customers require that losses associated with derivative transactions receive payment priority from any funds recovered should a customer default and ultimate disposition of collateral or guarantees occur.

Credit exposure to broker/dealer counterparties is managed through agreements with each derivative counterparty that require collateralization of fair value gains owed by such counterparties.  Some small degree of credit exposure exists due to timing differences between when a gain may occur and the subsequent point in time that collateral is delivered to secure that gain.  This is monitored by the Company and procedures are in place to minimize this exposure.  Such agreements also require the Company to collateralize counterparties in circumstances wherein the fair value of the derivatives result in loss to the Company.

Other provisions of such agreements include the definition of certain events that may lead to the declaration of default and/or the early termination of the derivative transaction(s):

If the Company either defaults or is capable of being declared in default on any of its indebtedness (exclusive of deposit obligations), then the Company could also be declared in default on its derivative obligations.
If a merger occurs that materially changes the Company's creditworthiness in an adverse manner.
--- ---
If certain specified adverse regulatory actions occur, such as the issuance of a Cease and Desist Order, or citations for actions considered Unsafe and Unsound or that may lead to the termination of deposit insurance coverage by the FDIC.
--- ---

The Bank also issues letters of credit, which are conditional commitments that guarantee the performance of a customer to a third party.  The credit risk involved and collateral obtained in issuing letters of credit are essentially the same as that involved in extending loan commitments to our customers.  In addition to customer related commitments, the Company is responsible for letters of credit commitments that relate to properties held in OREO.  The following table represents the Company’s contractual commitments due to letters of credit as of March 31, 2024, and December 31, 2023.

As of March 31, 2024, the Company evaluated current market conditions, including any impacts related to market interest rate changes and unused line of credit utilization trends during the first quarter of 2024, and based on that analysis under the CECL methodology, the Company determined credit losses related to unfunded commitments totaled $2.7 million.  The resultant decrease in the ACL for unfunded commitments of $44,000 for the first quarter of 2024, compared to the prior quarter end, is primarily related adjustments to historical benchmark assumptions, such as the funding rates and the period used to forecast those rates within the ACL calculation.  The Company will continue to assess the credit risk at least quarterly, and adjust the allowance for unfunded commitments, which is carried within other liabilities on our Consolidated Balance Sheets, as needed, with the appropriate offsetting entry to the provision for credit losses on our Consolidated Statements of Income.

Item 2.Management’s Discussion and Analysis of Financial Condition and Results of Operations

Overview

The following discussion provides additional information regarding our operations for the three months ended March 31, 2024, compared to the three months ended March 31, 2023, and our financial condition at March 31, 2024, compared to December 31, 2023.  This discussion should be read in conjunction with our consolidated financial statements as well as the financial and statistical data appearing elsewhere in this report and our Form 10-K for the year ended December 31, 2023.  The results of operations for the three months ended March 31, 2024, are not necessarily indicative of future results.  Dollar amounts presented in the following tables are in thousands, except per share data, and March 31, 2024 and 2023 amounts are unaudited.

In this report, unless the context suggests otherwise, references to the “Company,” “we,” “us,” and “our” mean the combined business of Old Second Bancorp, Inc. and its subsidiary bank, Old Second National Bank (the “Bank”).

We have made, and will continue to make, various forward-looking statements with respect to financial and business matters. Comments regarding our business that are not historical facts are considered forward-looking statements that involve inherent risks and uncertainties. Actual results may differ materially from those contained in these forward-looking statements. For additional information regarding our cautionary disclosures, see the “Cautionary Note Regarding Forward-Looking Statements” on page 3 of this report.

Business Overview

The Company is a bank holding company headquartered in Aurora, Illinois. Through our wholly-owned subsidiary bank, Old Second National Bank, a national banking organization also headquartered in Aurora, Illinois, we offer a wide range of financial services through our 48 banking centers located in Cook, DeKalb, DuPage, Kane, Kendall, LaSalle and Will counties in Illinois.  These banking centers offer access to a full range of traditional retail and commercial banking services including treasury management operations as well as fiduciary and wealth management services.  We focus our business on establishing and maintaining relationships with our clients while maintaining a commitment to provide for the financial services needs of the communities in which we operate.  We emphasize relationships with individual customers as well as small to medium-sized businesses throughout our market area.  We also have extensive wealth management services, which includes a registered investment advisory platform in addition to trust administration and trust services related to personal and corporate trusts and employee benefit plan administration services.

Our results of operations depend generally on net interest income, which is the difference between interest income from interest-earning assets and interest expense on interest-bearing liabilities. Net interest income is affected by regulatory, economic and competitive factors that influence interest rates, loan demand and deposit flows. In addition, we are subject to interest rate risk to the degree that our interest-earning assets mature or reprice at different times, or at different speeds, than our interest-bearing liabilities. Our results of operations are also affected by noninterest income, such as service charges, wealth management fees, loan fees, gains from the sale of newly originated loans, gains or losses on investments and certain other noninterest related items. Our principal operating expenses, aside from interest expense, consist of compensation and employee benefits, occupancy costs, professional fees, data processing expenses and provision for credit losses.

We are significantly impacted by prevailing economic conditions, including federal monetary and fiscal policies, and federal regulations of financial institutions. Deposit balances are influenced by numerous factors such as competing investments, the level of income and the personal rate of savings within our market areas. Factors influencing lending activities include the demand for housing and the interest rate pricing competition from other lending institutions.

As of March 31, 2024, all of our capital ratios were in excess of all regulatory requirements. While we believe that we have sufficient capital to withstand an extended economic recession, our reported and regulatory capital ratios could be adversely impacted by credit losses.

Financial Overview

Net income for the first quarter of 2024 was $21.3 million, or $0.47 per diluted share, compared to $23.6 million, or $0.52 per diluted share, for the first quarter of 2023. The decrease was primarily due to a reduction in net interest and dividend income from contraction in our securities portfolio as well as higher market rates and increased short-term borrowing, which resulted in a $7.5 million increase to interest expense. Partially offsetting these changes was growth in loan related income due to higher market interest rates in the first quarter of 2024 compared to the like quarter in 2023.  Noninterest income increased in the first quarter of 2024, compared to the like quarter of 2023, as a result of a reduction in net losses on security sales, growth in mortgage banking revenues, and an increase in the cash surrender value of BOLI.  An increase was also noted in noninterest expense for the current quarter, primarily due to higher salaries and employee benefits. Adjusted net income, a non-GAAP financial measure that excludes certain nonrecurring items, as applicable, was $21.3 million for the first quarter of 2024, compared to $19.1 million for the fourth quarter of 2023, and $23.4 million for the first quarter of 2023. See the discussion entitled “Non-GAAP Financial Measures” on page 40, as well as the table below, which provides a reconciliation of this non-GAAP measure to the most comparable GAAP equivalents.

The following provides an overview of some of the factors impacting our financial performance for the three month period ended March 31, 2024, compared to the like period ended March 31, 2023:

Net interest and dividend income was $59.8 million for the first quarter of 2024, compared to $64.1 million for the first quarter of 2023. The reduction in interest and dividend income in the first quarter of 2024 was primarily due to higher borrowing costs, partially offset by higher loan yields.

We recorded a net provision for credit losses of $3.5 million in the first quarter of 2024, driven by a $3.5 million increase in the allowance for credit losses on loans based on increased historical loss rate updates given current quarter charge-offs, our assessment of nonperforming loan metrics and trends, downward risk rating migration, and estimated future credit losses, net of a reversal of $44,000 in our allowance for unfunded commitments based on an adjustment of historical benchmark assumptions, such as funding rates and the period used to forecast those rates, within the ACL calculation.  We recorded a net provision for credit loss of $3.5 million in the first quarter of 2023.

Noninterest income was $10.5 million for the first quarter of 2024, compared to $7.4 million for the first quarter of 2023.  Contributing to the increase were security gains of $1,000 due to strategic sales in the first quarter of 2024, compared to losses on the sale of securities of $1.7 million in the first quarter of 2023.  Also contributing to the growth in noninterest income was a $291,000 increase in wealth management income, a $590,000 increase in mortgage banking revenue and a $930,000 increase in the cash surrender value of BOLI. These increases were partially offset by a decrease of $459,000 in other income primarily due to a one-time vendor credit received in the first quarter of 2023; no like credit was received in 2024.

​ 39

Table of Contents

Noninterest expense was $38.2 million for the first quarter of 2024, compared to $35.9 million for the first quarter of 2023, an increase of $2.3 million, or 6.5%.  Contributing to the increase in noninterest expense in the first quarter of 2024 was higher salaries and employee benefits as well as increases in occupancy furniture and equipment and computer and data processing expenses. Partially offsetting the increase in noninterest expense was a reduction in consulting & management fees and as well as OREO valuation reserve expense, which is included in other real estate expense, net.

We had a provision for income tax expense of $7.2 million for the first quarter of 2024, compared to a provision for income tax expense of $8.4 million for the first quarter of 2023. The effective tax rate for these two periods was 25.3% and 26.3%, respectively.

Our community-focused banking franchise experienced a decrease of $73.5 million in total loans in the first quarter of 2024, compared to the year ended December 31, 2023, and a decrease of $33.9 million in total loans compared to the first quarter of 2023.  We believe we are positioned for loan growth in 2024, though likely at a slower pace than in recent years, as we continue to serve our customers’ needs in a competitive economic environment. We continue to seek to provide value to our customers and the communities in which we operate, by executing on growth opportunities in our local markets and developing new banking relationships, while seeking to ensure the safety and soundness of our Bank, our customers, and our employees.

Nonaccrual loans decreased $3.3 million as of March 31, 2024, compared to December 31, 2023, but increased $763,000 compared to March 31, 2023. The reduction in nonaccrual loans in the first quarter of 2024, compared to the prior quarter, was primarily due to a $3.9 million partial charge-off on a large healthcare loan.  The increase in nonaccrual loans year over year is due to various downgrades in the last twelve months, primarily related to CRE-Owner Occupied and CRE-Investor portfolios, the majority of which are office and healthcare loans. Nonperforming loans as a percent of total loans was 1.6% as of March 31, 2024, compared to 1.7% as of December 31, 2023, and 1.6% as of March 31, 2023.  Classified assets increased to $140.6 million as of March 31, 2024, which is $2.7 million, or 1.9% more than December 31, 2023, and $14.0 million, or 11.1%, more than March 31, 2023.

Critical Accounting Estimates

Our consolidated financial statements are prepared based on the application of accounting policies in accordance with generally accepted accounting principles (“GAAP”) and follow general practices within the banking industry.  These policies require the reliance on estimates and assumptions, which may prove inaccurate or are subject to variations.  These estimates, assumptions, and judgments are based on information available as of the date of the consolidated financial statements.  Future changes in information may affect these estimates, assumptions, and judgments, which, in turn, may affect amounts reported in the consolidated financial statements.  Changes in underlying factors, assumptions, or estimates could have a material impact on our future financial condition and results of operations.

Of the significant accounting policies used in the preparation of our consolidated financial statements, we have identified certain items as critical accounting policies based on the associated estimates, assumptions, judgments and complexity. See “Management’s Discussion and Analysis of Financial Condition and Results of Operations—Critical Accounting Estimates” in our Annual Report on Form 10-K for the year ended December 31, 2023. There have been no material changes to our critical accounting policies or the estimates made pursuant to those policies during the most recent quarter from those disclosed in our 2023 Annual Report in Form 10-K.

Non-GAAP Financial Measures

This report contains references to financial measures that are not defined in GAAP. Such non-GAAP financial measures include the presentation of net interest income and net interest margin on a tax equivalent (“TE”) basis, adjusted net income, adjusted basic and diluted earnings per share, our adjusted efficiency ratio, and our tangible common equity to tangible assets ratio.  Management believes that the presentation of these non-GAAP financial measures (a) provides important supplemental information that contributes to a proper understanding of our operating performance, (b) enables a more complete understanding of factors and trends affecting our business, and (c) allows investors to evaluate our performance in a manner similar to management, the financial services industry, bank stock analysts, and bank regulators. Management uses non-GAAP measures as follows: in the preparation of our operating budgets, monthly financial performance reporting, and in our presentation of our performance to investors.  However, we acknowledge that these non-GAAP financial measures have a number of limitations. Limitations associated with non-GAAP financial measures include the risk that persons might disagree as to the appropriateness of items comprising these measures and that different companies might calculate these measures differently.  These measures should not be considered an alternative to our GAAP results.  A reconciliation of non-GAAP financial measures to the most directly comparable GAAP financial measures is presented below or alongside the first instance where each non-GAAP financial measure is used. 40

Overview

Three months ended March 31, 2024 and 2023

Our income before taxes was $28.5 million in the first quarter of 2024 compared to $32.0 million in the first quarter of 2023.  This decrease in pretax income was primarily due to a $4.3 million decrease in net interest and dividend income. Income before taxes was positively impacted by a $3.2 million increase in noninterest income, primarily due to $1,000 of security gains, net, in the first quarter of 2024 compared to $1.7 million of security losses, net, in the first quarter of 2023 as well as a $590,000 increase in mortgage banking income. Income before taxes was negatively impacted by a $2.3 million increase in noninterest expense primarily due to a $2.1 million increase in salary and employee benefits expense in the first quarter of 2024. Our net income was $21.3 million, or $0.47 per diluted share, for the first quarter of 2024, compared to net income of $23.6 million, or $0.52 per diluted share, for the first quarter of 2023. The Bank remains well positioned to navigate uncertain macroeconomics; we have mitigated interest rate risk, controlled expenses in an inflationary environment, and actively managed daily liquidity.  Furthermore, we continue to possess strong liquidity metrics and an outsized securities portfolio for funding needs.

Net interest and dividend income was $59.8 million in the first quarter of 2024, compared to $64.1 million in the first quarter of 2023.  The $4.3 million decrease was driven by an increase in interest expense in the first quarter of 2024, compared to the first quarter of 2023, primarily due to a rise in deposit interest rates and borrowing costs. Decreases in our securities portfolio also contributed to the decrease in net interest and dividend income during the first quarter of 2024. Partially offsetting the decrease during the first quarter of 2024 compared to the like quarter a year ago was growth in our loan related income due to the effect of higher market interest rates on our loan portfolios.

Net Interest Income

Net interest income, which is our primary source of earnings, is the difference between interest income earned on interest-earning assets, such as loans and investment securities, as well as accretion income on purchased loans, and interest incurred on interest-bearing liabilities, such as deposits and borrowings.  Net interest income depends upon the relative mix of interest-earning assets and interest-bearing liabilities, the ratio of interest-earning assets to total assets and of interest-bearing liabilities to total funding sources, and movements in market interest rates.  Our net interest income can be significantly influenced by a variety of factors, including overall loan demand, economic conditions, credit risk, the amount of nonearning assets including nonperforming loans and OREO, the amounts of and rates at which assets and liabilities reprice, variances in prepayment of loans and securities, early withdrawal of deposits, exercise of call options on borrowings or securities, a general rise or decline in interest rates, changes in the slope of the yield-curve, and balance sheet growth or contraction.

Three months ended March 31, 2024 and 2023

The increased yield of six basis points on interest earning assets compared to the linked period was driven by repricing within the existing loan portfolios, and, to a lesser extent, the growth in the average balance of loans over the quarter. In addition, rates paid on FHLB dividends increased quarter over linked quarter. Changes in the market interest rate environment impact earning assets at varying intervals depending on the repricing timeline of loans, as well as the securities maturity, paydown and purchase activities.

The year over year increase of 42 basis points on interest earning assets was primarily driven by significant increases to benchmark interest rates over the past twelve months, primarily impacting variable rate loans. This increase was partially offset by the reduction in securities available for sale income during the quarter ended March 31, 2024, compared to the prior quarter and year over year quarter, as both security volumes and rates decreased.

Average balances of interest-bearing deposit accounts have increased steadily since the fourth quarter of 2023 through the first quarter of 2024, from $2.74 billion to $2.76 billion, as time deposits increased due to CD rate specials, partially offset by reductions in other deposit categories as customers sought higher yielding products. We have continued to control the cost of funds over the periods reflected, with the average rate of overall interest-bearing deposits increasing to 118 basis points for the quarter ended March 31, 2024, from 89 basis points for the quarter ended December 31, 2023, and from 25 basis points for the quarter ended March 31, 2023. A 24 basis point increase in the cost of money market funds for the quarter ended March 31, 2024 compared to prior linked quarter, and a 110 basis point increase compared to the prior year like quarter were both due to select deposit account exception pricing, and drove a significant portion of the overall increase.  Average rates paid on time deposits for the quarter ended March 31, 2024 increased by 65 basis points and 229 basis points in the quarter over linked quarter and year over year quarters, respectively, primarily due to CD rate specials we offered.

Table of Contents Borrowing costs decreased in the first quarter of 2024, compared to the fourth quarter of 2023, primarily due to the $58.5 million decrease in average other short-term borrowings stemming from a decrease in average FHLB advances over the prior quarter. The increase of $131.4 million year over year of average FHLB advances was based on daily liquidity needs, and was the primary driver of the $2.2 million increase to interest expense due to other short-term borrowings. Subordinated and junior subordinated debt interest expense were essentially flat over each of the periods presented. Senior notes had the most significant interest expense decrease year over year, as we redeemed all of the $45.0 million senior notes, net of deferred issuance costs, in June 2023, resulting in senior notes having no balance after that time. In February 2023, we paid off the remaining balance of $9.0 million on the original $20.0 million term note issued in 2020, resulting in notes payable and other borrowings having no balance after that time.

Our net interest margin (GAAP) decreased four basis points to 4.55% for the first quarter of 2024, compared to 4.59% for the fourth quarter of 2023, and decreased 17 basis points compared to 4.72% for the first quarter of 2023.  Our net interest margin (TE) decreased four basis points to 4.58% for the first quarter of 2024, compared to 4.62% for the fourth quarter of 2023, and decreased 16 basis points compared to 4.74% for the first quarter of 2023.  The decrease in the first quarter of 2024, compared to the prior quarter, is driven by higher interest expense due to the current interest rate environment and its effect on interest bearing deposits. The decrease in the first quarter of 2024, compared to the prior year like quarter, is primarily due to an increase in market interest rates, and the related increase in costs of interest-bearing liabilities. See the discussion entitled “Non-GAAP Financial Measures” and the table on page 46 that provides a reconciliation of each non-GAAP measure to the most comparable GAAP equivalent.

​ 44

Table of Contents The increase in noninterest income of $3.2 million in the first quarter of 2024, compared to the first quarter of 2023, is primarily due to a $291,000 increase in wealth management income primarily due to an increase in advisory fees, a $590,000 increase in mortgage banking revenue mainly due to a $619,000 increase in MSRs mark to market gain, $1,000 of realized gains on sales of securities in the first quarter of 2024 compared to realized losses on the sale of securities of $1.7 million in the first quarter of 2023, a $930,000 increase in the cash surrender value of BOLI, and a $132,000 increase in card related income. These increases were partially offset by a $459,000 decrease in other income, as the 2023 period included a one-time credit from a software vendor of $457,000.

Table of Contents Noninterest expense for the first quarter of 2024 increased $1.2 million, or 3.3%, compared to the fourth quarter of 2023, and increased $2.3 million, or 6.5%, compared to the first quarter of 2023.  The increase in the first quarter of 2024 compared to the fourth quarter of 2023 was attributable to a $2.9 million increase in salaries and employee benefits, with increases reflected primarily in salaries due to annual merit increases, restricted stock expense and officers’ incentives due to annual payout true-ups, payroll taxes related to these annual payouts, and deferred executive compensation due to changes in market interest rates.  Also contributing to the noninterest expense increase in the first quarter of 2024 was a $110,000 increase in occupancy, furniture and equipment and an $84,000 increase in FDIC insurance.  Partially offsetting the increase in noninterest expense in the first quarter of 2024 compared to the fourth quarter of 2023 was a $191,000 decrease in advertising expense, a $61,000 decrease in card related expense, a $220,000 decrease in consulting & management fees, a $172,000 decrease in OREO related expense, and a $1.1 million decrease in other expense due to a $1.2 million litigation expense recorded in the fourth quarter of 2023 for a pending overdraft fee compliance claim.

The year over year increase in noninterest expense is primarily attributable to a $2.1 million increase in salaries and employee benefits, driven by increases in annual base salary rates, restricted stock expense, officers’ incentives, and deferred employee compensation due to market interest rate changes.  Also contributing to the increase was a $452,000 increase in occupancy, furniture and equipment, primarily due to branch remodeling and offset by net gains on sales of branches in 2023, and a $481,000 increase in computer and data processing partially due to core processor credits received in 2023. Partially offsetting the increase in noninterest expense in the first quarter of 2024, compared to the first quarter of 2023, was a $93,000 decrease in legal fees, a $454,000 decrease in consulting & management fees, and a $260,000 decrease in OREO related expenses.

Income Taxes

We recorded income tax expense of $7.2 million for the first quarter of 2024 on $28.5 million of pretax income, compared to income tax expense of $6.7 million on $24.9 million of pretax income in the fourth quarter of 2023, and income tax expense of $8.4 million on $32.0 million of pretax income in the first quarter of 2023. Our effective tax rate was 25.3% in the first quarter of 2024, 26.9% for the fourth quarter of 2023, and 26.3% for the first quarter of 2023.  The slight reduction in the effective tax rate for the first quarter of 2024 reflects the impact of credits to tax expense related to vested stock awards in the first quarter 2024, which occurs annually each February; these stock awards were larger in the first quarter of 2024 than the like 2023 period.

Income tax expense reflected all relevant statutory tax rates and GAAP accounting.  There were no significant changes in our ability to utilize our deferred tax assets during the quarter ended March 31, 2024.  We had no valuation reserve on the deferred tax assets as of March 31, 2024.

Financial Condition

Total assets decreased $106.7 million to $5.62 billion at March 31, 2024, from $5.72 billion at December 31, 2023, due primarily to the decrease of $24.0 million in securities available-for-sale, the decrease of $73.5 million in total loans, and the $5.6 million decrease in other assets.  The decrease in securities available-for-sale was primarily due to paydowns and strategic sales. These decreases were partially offset by increases in premises and equipment of $2.0 million and BOLI of $1.2 million. We continue to actively assess potential investment opportunities to utilize our excess liquidity. Total deposits were $4.61 billion at March 31, 2024, an increase of $37.5 million from December 31, 2023, primarily due to seasonal tax refunds, as well as deposit rate specials.

Table of Contents Securities available-for-sale decreased $24.0 million as of March 31, 2024 compared to December 31, 2023, and decreased $286.3 million compared to March 31, 2023. The decrease in the portfolio during the first quarter of 2024 was driven by paydowns totaling $30.7 million, securities sales totaling $5.3 million, and maturities totaling $2.0 million, partially offset by $15.7 million in purchases. We continue to seek to position the portfolio in higher credit quality, shorter duration securities with an appropriate mix of fixed- and floating-rate exposures.

Total loans were $3.97 billion as of March 31, 2024, a decrease of $73.5 million from December 31, 2023.  The decrease in total loans in the first three months of 2024, compared to December 31, 2023, was due primarily to paydowns, net of originations, within commercial of $45.1 million, commercial real estate – investor of $16.0 million and multifamily of $14.2 million offset by net increases in leases of $27.4 million from December 31, 2023.  Total loans decreased $33.9 million from March 31, 2023 to March 31, 2024, primarily due to paydowns, net of originations, within commercial of $55.2 million, commercial real estate - investor of $38.4 million, and commercial real estate – owner occupied of $87.5 million, offset by net increases in leases of $139.8 million and multifamily of $28.5 million.  As required by CECL, the balance (or amortized cost basis) of purchased credit deteriorated loans, or PCD loans (discussed below) is carried on a gross basis (rather than net of the associated credit loss estimate), and the expected credit losses for PCD loans are estimated and separately recognized as part of the allowance for credit losses, or ACL.

The quality of our loan portfolio is impacted not only by our credit decisions but also by the economic health of the communities in which we operate.  Since we are located in a corridor with significant open space and undeveloped real estate, real estate lending (including commercial real estate, construction, residential, multifamily, and HELOCs) has been and continues to be a sizeable portion of our portfolio. These categories comprised 68.7% of the portfolio as of March 31, 2024, compared to 68.8% of the portfolio as of December 31, 2023.  At March 31, 2024, our outstanding commercial real estate loans and undrawn commercial real estate commitments, excluding owner occupied real estate were equal to 268.8% of our Tier 1 capital plus allowance for credit losses, a decrease from 286.9% at December 31, 2023.  We continue to oversee and seek to manage our loan portfolio in accordance with interagency guidance on risk management.

Asset Quality

Nonperforming loans consist of nonaccrual loans and loans 90 days or greater past due. Nonperforming loans decreased by $3.7 million to $65.1 million at March 31, 2024 from $68.8 million at December 31, 2023 and increased $586,000 from $64.5 million at March 31, 2023. Purchased credit deteriorated loans, or PCD loans, are purchased loans that, as of the date of acquisition, we determined had experienced a more-than-insignificant deterioration in credit quality since origination.  PCD loans and their related deferred loan costs are included in our nonperforming loan disclosures, if such loans otherwise meet the definition of a nonperforming loan.  Management continues to carefully monitor loans considered to be in a classified status.  Nonperforming loans as a percent of total loans were 1.6% as of March 31, 2024, 1.7% as of December 31, 2023, and 1.6% as of March 31, 2023.  The distribution of our nonperforming loans is shown in the following table.

Net charge-offs of $3.7 million were recorded for the first quarter of 2024, compared to net charge-offs of $15.5 million for the fourth quarter of 2023, and net charge-offs of $740,000 for the first quarter of 2023, reflecting continuing management attention to credit quality and remediation efforts.  The net charge-offs for the first quarter of 2024 were primarily due to a $3.9 million charge off of a commercial real estate – owner occupied loan. The commercial real estate – owner occupied credit had a reported reserve allocation of $3.9 million prior to the first quarter of 2024 charge-off. We have continued our conservative loan valuations and aggressive recovery efforts on prior charge-offs.

Classified loans include nonaccrual loans and all other loans considered substandard. Classified assets include both classified loans and OREO.  Loans classified as substandard are inadequately protected by either the current net worth and ability to meet payment obligations of the obligor, or by the collateral pledged to secure the loan, if any.  These loans have a well-defined weakness or weaknesses that jeopardize the liquidation of the debt and carry the distinct possibility that we will sustain some loss if deficiencies remain uncorrected.

Table of Contents Total classified loans and classified assets increased $2.7 million as of March 31, 2024 from December 31, 2023. The increase since December 31, 2023 is due to the additions of $15.9 million, the majority of which consisted of three relationships totaling $14.7 million. Commercial loans were the majority of the additions, consisting of seven loans totaling $11.6 million and one relationship in commercial real estate – owner occupied totaling $3.3 million. The additions are offset by $13.2 million of outflows, most driven by $6.3 million of loan rating upgrades, and a $3.9 million partial charge off. The increase from March 31, 2023 is primarily due to additions to commercial real estate – owner occupied. Management monitors a ratio of classified assets to the sum of Bank Tier 1 capital and the ACL on loans as another measure of overall change in loan related asset quality, which is referred to as the “classified assets ratio.” The classified assets ratio was 21.33% for the period ended March 31, 2024, compared to 21.66% as of December 31, 2023, and 20.04% as of March 31, 2023.

Allowance for Credit Losses on Loans

The provision for credit losses, which includes a provision for losses on unfunded commitments, is a charge to earnings to maintain the allowance for credit losses (“ACL”) at a level consistent with management’s assessment of expected losses in the loan portfolio at the balance sheet date.

At March 31, 2024, our ACL on loans totaled $44.1 million, and our ACL on unfunded commitments, included in other liabilities, totaled $2.7 million. In the first quarter of 2024, we recorded provision expense on loans of $3.5 million, based on historical loss rates, our assessment of nonperforming loan metrics and trends, downward risk rating migrations, and estimated future credit losses, and a $44,000 reversal of provision on unfunded commitments, primarily due to an adjustment of historical benchmark assumptions, such as funding rates and the period used to forecast those rates, within the ACL calculation.  These adjustments resulted in a $3.5 million net impact to the provision for credit losses for the first quarter of 2024.

Management estimates the amount of provision required on a quarterly basis and records the appropriate provision expense, or release of expense, to maintain an adequate reserve for all potential and estimated credit losses on loans, leases and unfunded commitments.  The ACL on loans totaled $44.1 million as of March 31, 2024, $44.3 million as of December 31, 2023, and $53.4 million as of March 31, 2023.  Our ACL on loans to total loans was 1.1% as of March 31, 2024, compared to 1.1% as of December 31, 2023 and 1.3% as of March 31, 2023.  See Item 7 – Critical Accounting Estimates in the Management Discussion and Analysis in our 2023 Annual Report in Form 10-K for discussion of our ACL methodology on loans. Allocations of the ACL may be made for specific loans, but the entire allowance is available for any loan that, in our judgment, should be charged-off. 51

The coverage ratio of the ACL on loans to nonperforming loans was 67.8% as of March 31, 2024, which was an increase from the coverage ratio of 64.4% as of December 31, 2023 and a decrease from 82.7% as of March 31, 2023.  When measured as a percentage of average loans, our total ACL on loans was 1.10% at March 31, 2024, 1.10% at December 31, 2023, and 1.36% at March 31, 2023.

In management’s judgment, an adequate ACL has been established to encompass the current lifetime expected credit losses at March 31, 2024, and general changes in lending policy, procedures and staffing, as well as other external factors.  However, there can be no assurance that actual losses will not exceed the estimated amounts in the future, based on unforeseen economic events, changes in business climates and the condition of collateral at the time of default and repossession.  Continued volatility in the economic environment stemming from the impacts of and response to inflation, potential recession, and the war in Ukraine and the conflict in the Middle East, and the associated effects on our customers, or other factors, such as changes in business climates and the condition of collateral at the time of default or repossession, may revise our current expectations of future credit losses in future reporting periods.

As of March 31, 2024, OREO totaled $5.1 million, reflecting no change from December 31, 2023, and an increase of $3.9 million from $1.3 million at March 31, 2023. There were no property additions or disposals in the OREO portfolio in the first quarter of 2024. No valuation adjustments occurred in the first quarter of 2024 or in the fourth quarter of 2023. In the first quarter of 2023, we recorded two write-downs totaling $273,000 as well as a write-up for $4,000, totaling a net $269,000 increase in valuation reserve.

Table of Contents Total deposits were $4.61 billion at March 31, 2024, which reflects a $37.5 million increase from total deposits of $4.57 billion at December 31, 2023, and a decrease of $288.9 million from total deposits of $4.90 billion at March 31, 2023.  The increase in deposits at March 31, 2024, compared to December 31, 2023, was primarily due to increases in time deposits of $58.7 million and money market and NOW accounts of $29.6 million, partially offset by decreases in noninterest bearing deposits of $35.0 million and savings accounts of $15.8 million. The decrease in deposits at March 31, 2024, compared to March 31, 2023, was primarily due to decreases in noninterest bearing deposits of $150.2 million, savings accounts of $153.1 million, and money market accounts of $102.9 million, partially offset by an increase in time deposits of $155.7 million.  Total quarterly average deposits decreased $417.9 million, or 8.4%, in the year over year period, driven by declines in our average demand deposits of $183.3 million, and savings, NOW and money markets combined of $358.4 million, partially offset by an increase in average time deposits of $123.8 million year over year. In general, the bulk of the decline in deposits year over year can be characterized as rate sensitive with significant flows and transfers into investing activities.

Deposits increased 0.8% for the three months ended March 31, 2024, which reflects that our efforts on retaining and acquiring new deposits have been effective. Competitive rate pressures have eased, however, there is a continued remix into our time deposits and interest bearing accounts, drawn by higher rates. Overall, our deposit level remains stable as we continue to monitor customer relationships and liquidity closely.

In addition to deposits, we used other liquidity sources for our funding needs in all periods presented, such as repurchase agreements and other short-term borrowings with the FHLBC. Securities sold under repurchase agreements totaled $33.5 million at March 31, 2024, a $7.1 million, or 26.7%, increase from $26.5 million at December 31, 2023, and an increase of $5.6 million, or 20.2%, from March 31, 2023. The outstanding balance of our short-term FHLBC borrowings was $220.0 million as of March 31, 2024, $405.0 million as of December 31, 2023, and $315.0 million as of March 31, 2023.

We are also indebted on $25.8 million of junior subordinated debentures, net of deferred issuance costs, as of March 31, 2024, which are related to the trust preferred securities issued by its statutory trust subsidiary, Old Second Capital Trust II (“Trust II”). The Trust II issuance converted from fixed to floating rate at three month LIBOR, which is now three month Term SOFR, plus 150 basis points beginning June 15, 2017.  Upon conversion to a floating rate, we initiated a cash flow hedge which resulted in the total interest rate paid on this debt of 4.37% as of March 31, 2024, as compared to 6.77%, which was the rate paid during the period prior to the June 15, 2017 rate reset.

In the second quarter of 2021, we entered into Subordinated Note Purchase Agreements with certain qualified institutional buyers pursuant to which we issued $60.0 million in aggregate principal amount of our 3.50% Fixed-to-Floating Rate Subordinated Notes due April 15, 2031 (the “Notes”).  We sold the Notes to eligible purchasers in a private offering, and the proceeds of this issuance were used for general corporate purposes. The Notes bear interest at a fixed annual rate of 3.50% through April 14, 2026, payable semi-annually in arrears.  As of April 15, 2026 forward, the interest rate on the Notes will generally reset quarterly to a rate equal to three-month Term SOFR (as defined by the Note) plus 273 basis points, payable quarterly in arrears.  The Notes have a stated maturity of April 15, 2031, and are redeemable, in whole are in part, on April 15, 2026, or any interest payment date thereafter, and at any time upon the occurrence of certain events. As of March 31, 2024, we had $59.4 million of subordinated debentures outstanding, net of deferred issuance costs.

In December 2016, we completed a $45.0 million senior note issuance. The notes had a ten-year term, and included interest payable semiannually at 5.75% for five years. Beginning December 31, 2021, the interest became payable quarterly at three month LIBOR plus 385 basis points. On June 30, 2023, the senior notes were redeemed in full.  The remaining balance of deferred debt issuance costs of $362,000 related to these senior notes was recognized as interest expense as of June 30, 2023. 54

Table of Contents On February 24, 2023, we paid off the remaining $9.0 million balance in notes payable and other borrowings, resulting in no balance in this line item as of March 31, 2024, December 31, 2023, and March 31, 2023. The balance in notes payable was related to a $20.0 million term note originated with a correspondent bank in the first quarter of 2020, to facilitate the redemption of our Old Second Capital Trust I trust preferred securities and related junior subordinated debentures, completed on March 2, 2020.

Capital

As of March 31, 2024, total stockholders’ equity was $596.2 million, which was an increase of $18.9 million from $577.3 million as of December 31, 2023.  This increase was largely attributable to net income of $21.3 million in the first three months of 2024, partially offset by $2.2 million of dividends paid to our common stockholders. In addition, total stockholders’ equity as of March 31, 2024 increased over December 31, 2023, due to a reduction in unrealized net losses on available-for-sale securities, which contributed to the overall decrease in accumulated other comprehensive loss of $580,000 in the first three months of 2024, due to changes in market interest rates.  Total stockholders’ equity as of March 31, 2024 increased $99.3 million compared to March 31, 2023 due to net income year over year and the decrease in accumulated other comprehensive loss of $15.7 million year over year.

As part of its response to the impact of the COVID-19 pandemic, in the first quarter of 2020, U.S. federal regulatory authorities issued an interim final rule that provided banking organizations that adopted CECL during the 2020 calendar year with the option to delay for two years the estimated impact of CECL on regulatory capital relative to regulatory capital determined under the prior incurred loss methodology, followed by a three-year transition period to phase out the aggregate amount of the capital benefit provided during the initial two-year delay (i.e., a five-year transition in total). In connection with our adoption of CECL on January 1, 2020, we elected to utilize the five-year CECL transition.  As of March 31, 2024, our capital measures exclude $951,000, which is the modified CECL transition adjustment.

As of March 31, 2024, the Company, on a consolidated basis, exceeded the minimum capital ratios to be deemed “well capitalized” and met the capital conservation buffer requirements.  In addition to the above regulatory ratios, our GAAP common equity to total assets ratio, which is used as a performance measurement for capital analysis and peer comparisons, increased from 10.09% at December 31, 2023, to 10.62% at March 31, 2024. Our GAAP tangible common equity to tangible assets ratio was 9.04% at March 31, 2024, compared to 8.53% as of December 31, 2023.  Our non-GAAP tangible common equity to tangible assets ratio, which management also considers a valuable performance measurement for capital analysis, increased from 8.56% at December 31, 2023, to 9.08% at March 31, 2024, primarily due to an increase in tangible common equity in the first quarter of 2024.  The increase in tangible common equity was primarily due to an increase in retained earnings of $19.1 million.

Liquidity

Liquidity is our ability to fund operations, to meet depositor withdrawals, to provide for customers’ credit needs, and to meet maturing obligations and existing commitments.  Our liquidity principally depends on our cash flows from operating activities, investment in and maturity of assets, changes in balances of deposits and borrowings, and our ability to borrow funds. In the first quarter of 2024, we experienced a decrease in loans, while deposits trended up as the rates offered on our deposit products remain competitive to peers.  We managed the change in our funding through borrowing from the Federal Home Loan Bank of Chicago (“FHLBC”) and sales of securities, which resulted in minimal losses and mitigated our interest rate risk profile.  The bank failures that occurred in 2023 exemplify the potentially serious results of the unexpected inability of insured depository institutions to obtain needed liquidity to satisfy deposit withdrawal requests, including how quickly such requests can accelerate once uninsured depositors lose confidence in an institution’s ability to satisfy its obligations to depositors. We seek to ensure our funding needs are met by maintaining a level of liquidity through asset and liability management. We monitor our borrowing capacity at the FHLBC as part of our liquidity management process as supervised by our Asset and Liability Committee (“ALCO”) and reviewed by our Board of Directors.  In addition, our senior management team monitors cash balances daily to ensure we have adequate liquidity to meet our operational and financing needs.  As of March 31, 2024, our cash on hand liquidity totaled $98.1 million, a decrease of $2.1 million over cash balances held as of December 31, 2023.

Net cash inflows from operating activities were $47.3 million during the first three months of 2024, compared with net cash inflows of $35.0 million in the same period of 2023.  Proceeds from sales of loans held-for-sale, net of funds used to originate loans held-for-sale, were a source of inflows for the first three months of 2024 compared to a source of outflows for the like period of 2023.  Interest paid, net of interest received, combined with changes in other assets and liabilities were a source of inflows for the three months ended March 31, 2024 and source of outflows for the like period of 2023. The management of investing and financing activities, as well as market conditions, determines the level and the stability of net interest cash flows.  Management’s policy is to mitigate the impact of changes in market interest rates to the extent possible, as part of the balance sheet management process.

Net cash inflows from investing activities were $93.9 million in the three months ended March 31, 2024, compared to net cash outflows of $42.9 million in the same period in 2023.  In the first three months of 2024, securities transactions accounted for net inflows of $22.3 million, and the principal change on loans accounted for net inflows of $70.0 million.  In the first three months of 2023, securities transactions accounted for net inflows of $99.7 million, and principal on loans funded, net of paydowns, accounted for net outflows of $132.4 million.

​ 56

Table of Contents Net cash outflows from financing activities in the three months ended March 31, 2024, were $143.2 million, compared with net cash outflows of $4.2 million in the three months ended March 31, 2023.  Net deposit inflows in the first three months of 2024 were $37.6 million compared to net deposit outflows of $213.1 million in the first three months of 2023.  Other short-term borrowings had $185.0 million of net cash outflows in the first three months of 2024, compared to net cash inflows of $225.0 million for other short-term borrowings in the first three months of 2023.  Changes in securities sold under repurchase agreements accounted for inflows of $7.1 million and outflows of $4.3 million for the three months ended March 31, 2024 and 2023, respectively.  Dividends paid on our common stock totaled $2.2 million for both the three months ended March 31, 2024 and 2023.  Vesting of restricted stock accounted for inflows of $99,000 in the three months ended March 31, 2024, compared to no cash flows from vestings of restricted stock in the same period of 2023. The purchase of treasury stock in the first three months of 2024 due to shares acquired with equity award vestings resulted in outflows of $776,000, compared to cash outflows of $605,000 in the first three months of 2023 related to shares acquired from equity award vestings.

Cash and cash equivalents for the three months ended March 31, 2024, totaled $98.1 million, as compared to $100.1 million as of December 31, 2023 and $103.0 million as of March 31, 2023.  The decrease in cash and cash equivalents for the three months ended March 31, 2024 was mainly attributable to the decrease in FHLB advances during the period, partially offset by the decrease in our loan portfolio, sales of securities, and the increase in customer deposits during the first three months of 2024. The year over year decrease is driven by decreased FHLB advances and increased customer use of deposits, partially offset by a decline in loans and sales of securities. In addition to cash and cash equivalents on hand or held as deposits with other financial institutions, we rely on funding sources from customer deposits, cash flows from securities available-for-sale and loans, and a line of credit with the FHLBC to meet potential liquidity needs.  These sources of liquidity are immediately available to satisfy any funding requirements due to depositor or borrower demands through the ordinary course of our business.  Additional sources of funding include a $30.0 million undrawn line of credit held by the Company with a third party financial institution, as well as unpledged securities available-for-sale.

Table of Contents Item 3. Quantitative and Qualitative Disclosures about Market Risk

Interest Rate Risk

As part of our normal operations, we are subject to interest-rate risk on the assets we invest in (primarily loans and securities) and the liabilities we fund (primarily customer deposits and borrowed funds).  Fluctuations in interest rates may result in changes in the fair market values of our financial instruments, cash flows, and net interest income.  Like most financial institutions, we have an exposure to changes in both short-term and long-term interest rates. A financial institution’s ability to be relatively unaffected by changes in interest rates is a good indicator of its capability to perform in a volatile rate environment.  We mitigate the impact of interest rate volatility to the Bank by managing our rate sensitivity under various scenarios.

The Federal Reserve Board (“FRB”) held rates unchanged in the first quarter of 2024, which was widely expected by market participants.  The timing of rate cuts and implied Federal Funds Rate for 2024 have shifted, with a current outlook for higher rates for a longer time given an increase in the latest Consumer Price Index (“CPI”) data and continued economic activity.  The FRB continued to shrink its balance sheet, ending 2023 at $7.7 trillion, down from a peak of $8.7 trillion in March 2023.

We manage interest rate risk within guidelines established by policy which are intended to limit the amount of rate exposure.  In practice, we seek to manage our interest rate risk exposure within our guidelines so that such exposure does not pose a material risk to our future earnings.  We manage various market risks in the normal course of our operations, including credit, liquidity risk, and interest-rate risk.  Other types of market risk, such as foreign currency exchange risk and commodity price risk, do not arise in the normal course of our business activities and operations.  In addition, since we do not hold a trading portfolio, we are not exposed to significant market risk from trading activities.  Our interest rate risk exposures at March 31, 2024 and December 31, 2023 are outlined in the table below.

Our net income can be significantly influenced by a variety of external factors, including: overall economic conditions, policies and actions of regulatory authorities, the amounts of and rates at which assets and liabilities reprice, variances in prepayment of loans and securities other than those that are assumed, early withdrawal of deposits, exercise of call options on borrowings or securities, competition, a general rise or decline in interest rates, changes in the slope of the yield-curve, changes in historical relationships between indices (such as SOFR and Prime), and balance sheet growth or contraction.  Our asset-liability committee seeks to manage interest rate risk under a variety of rate environments by structuring our on-balance sheet and off-balance sheet positions, which includes interest rate swap derivatives as discussed in Note 19 of our consolidated financial statements found in in our Annual Report on Form 10-K for the year ended December 31, 2023.  We seek to monitor and manage interest rate risk within approved policy guidelines and limits.  Asset and liability modeling and tracking is performed and presented to the asset-liability committee and the Board of Directors no less than quarterly. The presentations discuss our current and historical interest rate risk posture, shifts in the balance sheet composition, and the impact of interest rate movements on earnings and equity.  Our current balance sheet is a moderately asset sensitive profile, as our variable rate assets reprice faster than our longer duration, low beta deposit base. The market events of failed liquidity management at other banks have been discussed and reviewed by the asset-liability committee. The committee concluded that we continue to have a strong liquidity position and no new liquidity risks were identified.  Prudently, we added new measures to assess liquidity risk and enhanced our reports to segment deposits by insured, uninsured, collateralized deposits; and monitor the bank’s funding sources and uses on a regular basis.

We also have a Risk Committee, chaired by our Chief Risk Officer, which reports no less than quarterly to senior management as well as our Board of Directors regarding compliance with risk tolerance limits, key risk factor changes, both internally and externally, due to portfolio changes as well as market conditions. Our enterprise risk management framework is governed by this committee, with input being provided by line of business managers, senior management and the Board.

We use simulation analysis to quantify the impact of various rate scenarios on our net interest income. Specific cash flows, repricing characteristics, and embedded options of the assets and liabilities held by us are incorporated into the simulation model. Earnings at risk are calculated by comparing the net interest income of a stable interest rate environment to the net interest income of a different interest rate environment in order to determine the percentage change. As of March 31, 2024, our net interest income profile remained sensitive to earnings gains (in both dollars and percentage) should interest rates rise.  Our profile is slightly more asset sensitive compared to December 31, 2023, due to a decrease in operating borrowings from principal return on Assets, mild increase in funding, and cashflow from earnings.

Table of Contents The following table summarizes the effect on annual income before income taxes based upon an immediate increase or decrease in interest rates of 0.5%, 1.0%, and 2.0%, with no change in the slope of the yield curve.

Percent change (14.7) % (7.3) % (3.6) % 3.8 % 7.6 % 14.7 %

The amounts and assumptions used in the simulation model should not be viewed as indicative of expected actual results.  Actual results will differ from simulated results due to timing, magnitude, balance sheet composition and frequency of interest rate changes as well as changes in market conditions and management strategies.  The above results do not take into account any management action to mitigate potential risk.

Effects of Inflation

In management’s opinion, although changes in interest rates affect our financial condition to a far greater degree than changes in the inflation rate, we monitor both.  The annual US inflation rate for March 2024 was 3.5%, up from 3.4% quarter-over-quarter, while Core CPI continued to decline to 3.8%.  Management believes the inflation rate will continue to trend down, albeit at a much slower rate than 2023.  The downside risks of high inflation put upwards pressure to our expenses, which could impact our profits.  Furthermore, higher costs of living weaken the financial condition of our borrowers which could affect our credit profile.  Inflation has declined to a comfortable level and has minimal direct impact to our results.

Item 4. Controls and Procedures

Evaluation of Disclosure Controls and Procedures

The Chief Executive Officer and Chief Financial Officer have evaluated the effectiveness of the design and operation of the Company’s disclosure controls and procedures, as defined in Rule 13a-15(e) promulgated under the Securities and Exchange Act of 1934, as amended, as of March 31, 2024.  Based on that evaluation, the Chief Executive Officer and Chief Financial Officer concluded that as of March 31, 2024, the Company’s internal controls were effective to ensure that information required to be disclosed by the Company in reports that it files or submits under the Securities and Exchange Act of 1934 is recorded, processed, summarized, and reported within the time periods specified.

There were no changes in the Company’s internal controls over financial reporting during the quarter ended March 31, 2024, that have materially affected, or are reasonably likely to materially affect, the Company’s internal control over financial reporting.

The design of any system of controls and procedures is based in part upon certain assumptions about the likelihood of future events. There can be no assurance that any design will succeed in achieving its stated goals under all potential future conditions, regardless of how remote.

Item 1.  Legal Proceedings

The Company and its subsidiaries, from time to time, are involved in collection suits in the ordinary course of business against its debtors and are defendants in legal actions arising from normal business activities.  Management, after consultation with legal counsel, believes that the ultimate liabilities, if any, resulting from these actions will not have a material adverse effect on the financial position of the Bank or on the consolidated financial position of the Company.

Item 1.A.  Risk Factors

Investing in shares of our common stock involves certain risks, including those identified and described in Item 1A of our Annual Report on Form 10-K for the fiscal year ended December 31, 2023, as well as cautionary statements contained in this Quarterly Report, on Form 10-Q, including those under the caption “Cautionary Note Regarding Forward-Looking Statements.”

There have been no material changes to the risk factors previously disclosed in the Company’s (i) Annual Report on Form 10-K for the fiscal year ended December 31, 2023.

Item 2.  Unregistered Sales of Equity Securities and Use of Proceeds

Stock Repurchases

In December 2023, our board of directors authorized the repurchase of up to 2,234,896 shares of our common stock (the “Repurchase Program”). The Company received notice of non-objection in January 2024 from the Federal Reserve Bank of Chicago for the Repurchase Program. Under the Repurchase Program, repurchases may be made through December 31, 2024, will not exceed $17.50 per share, and the aggregate value of share repurchases will not exceed $39.1 million. We may make repurchases under the Repurchase Program from time to time through open market purchases, trading plans established in accordance with SEC rules, privately negotiated transactions, or by other means.

The actual means and timing of any repurchases, quantity of purchased shares and prices will be, subject to certain limitations, at the discretion of management and will depend on a number of factors, including, without limitation, market prices of our common stock, general market and economic conditions, and applicable legal and regulatory requirements.   Repurchases under the Repurchase Program may be initiated, discontinued, suspended or restarted at any time provided that repurchases under the Repurchase Program after December 31, 2024, would require Federal Reserve non-objection or approval.  We are not obligated to repurchase any shares under the Repurchase Program.
