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 September 30, ~~2022,~~2023 are not necessarily indicative of the results that may be expected for the year ending December 31, ~~2022.~~2023. 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, ~~2021.~~2022. 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.

~~See~~ ~~“Management’s Discussion and Analysis of Financial Condition and Results of Operations—Critical Accounting Estimates”~~ ~~and~~ ~~Note 1 – Summary of Significant Accounting Policies,~~ both found in our Annual Report on Form 10-K for the year ended December 31, 2021, for further discussion of our Allowance for Credit Losses methodology, which now implements Accounting Standards Update (ASU) No. 2016-13, “~~Financial Instruments – Measurement of Credit Losses on Financial Instruments (Topic 326)~~,” also known as Current Expected Credit Losses, or CECL. ASU 2016-13, which is considered a critical accounting estimate, is effective for financial statements issued for fiscal years beginning after December 15, 2019, and was adopted as of January 1, 2020, by the Company.

Recent Accounting Pronouncements

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

ASU 2018-16, ASU 2020-04, ASU 2021-01, and ASU ~~2021-01~~2022-06 – In October 2018, the Financial Standards Board, or FASB, issued ASU No. 2018-16 “Derivatives and Hedging (Topic 815): Inclusion of the Secured Overnight Financing Rate (SOFR) Overnight Index Swap (OIS) Rate as a Benchmark Interest Rate for Hedge Accounting.” ASU 2018-16 adds the SOFR overnight index swap rate to the list of United States (U.S.) benchmark rates eligible for hedge accounting purposes, which is the fourth rate permissible to be used as a U.S. benchmark rate. This guidance iswas effective for annual and interim periods beginning after December 15, 2018, and ~~we do~~did not ~~expect this guidance to~~ have a material impact on the financial condition or liquidity of the Company. ASU 2020-04 and ASU 2021-01 Reference Rate Reform (Topic 848) were issued on March 12, 2020 and January 7, 2021, respectively, and each provide further guidance on optional expedients and exceptions for applying GAAP to contract modifications and hedging relationships due to the discontinuation of LIBOR. In addition, on March 5, 2021, the International Swaps and Derivatives Association (“ISDA”) issued a statement with an “Index Cessation Event Announcement,” which confirmed the extension of the cessation of LIBOR-referenced rates from December 31, 2021, to June 30, 2023, for certain rate tenors.ASU 2022-06 further defers the sunset date of Topic 848 from December 31, 2022, to December 31, 2024, after which entities will no longer be permitted to apply the relief in Topic 848.

The Company formed a LIBOR transition team in 2019 and ~~has~~ developed a project plan to assess the use of alternative indexes and to seek to ensure all financial instruments that reference LIBOR are identified, quantified, and researched for the LIBOR fallback language available or needed. The Company ~~has~~ completed the ISDA protocol adherence for LIBOR fallback language for all commercial swaps, ~~has~~ met with its commercial loan clients to also guide their swap fallback language adherence, and worked to revise all credit documents being issued by Old Second National Bank (the “Bank”) for new loans to ensure appropriate fallback language iswas included. We ~~have~~ discontinued the use of LIBOR as a reference rate for all consumer loans issued after July 31, 2021, and all commercial loans issued after December 31, 2021, with certain exceptions for those loans that were in the process of funding at the end of 2021. The Company’s systems ~~have been~~were updated to handle multiple SOFR-based indexes and we ~~continue to meet regularly to plan~~planned accordingly for the transition of existing LIBOR exposures ~~prior to~~as the final LIBOR cessation date ofwas June 30, 2023. As of September 30, 2023, the Company’s LIBOR transition processes were determined to be completed and alternative index rates are in place.

ASU 2022-01 – On March 28, 2022, the FASB issued ASU 2022-01 “Derivatives and Hedging (Topic 815): Fair Value Hedging – Portfolio Layer Method.” ASU 2022-01 is effective for public business entities for fiscal years beginning after December 15, 2022, and also interim periods within those fiscal years. Early adoption is permitted if an entity has adopted ASU No. 2017-12 concurrently or prior. The goal of this new hedging standard is to better align the economic results of risk management activities with hedge accounting, by allowing multiple layers of a single closed portfolio to be hedged, as compared to the single-layer, or last of layer method, allowed with the adoption of ASU 2017-12.

~~The Company is currently reviewing~~ ASU 2022-01 is effective for public business entities for fiscal years beginning after December 15, 2022, and interim periods within those fiscal years, and was adopted by the ~~impact to derivative measurement and disclosures, and will assess any revisions needed for reporting purposes in the next quarter. We anticipate adopting ASU 2022-01 no later than~~Company as of January 1, 2023. ~~We do not expect a~~There was no material impact ~~upon adoption.~~of the pronouncement to the financial statements of the Company.

ASU 2022-02 – On March 31, 2022, the FASB issued ASU 2022-02 “Financial Instruments-Credit Losses (Topic 326): Troubled Debt Restructurings and Vintage Disclosures.” ~~ASU 2022-02 is effective for any entities that have adopted CECL, and is effective for fiscal years beginning after December 15, 2022, including interim periods within those years.~~ The amendments eliminate certain troubled debt restructuring (“TDR”) recognition and measurement guidance previously in effect, and consideration of the TDRs similar to other modified loans under CECL is now required. ASU 2022-02 also requires enhancements to vintage loan disclosures, requiring detail be provided on current-period gross write-offs and disclosure of the amortized cost basis of financing receivables by credit quality indicators and by loan portfolio class of the gross charge-off based on year of origination.

~~The Company is currently reviewing~~ ASU 2022-02 was effective for fiscal years beginning after December 15, 2022, including interim periods within those years, and was adopted prospectively by the ~~impact to TDR recognition, measurement and disclosures, and will assess any revisions needed for reporting purposes in the next quarter. We anticipate adopting ASU 2022-02~~Company as of January 1, 2023. There was no material impact of the pronouncement to 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, ~~2021.~~2022. 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 third quarter of ~~2022,~~2023, the Company had no changes to significant accounting policies or estimates.

Subsequent Events

On October ~~18, 2022,~~17, 2023, our Board of Directors declared a cash dividend of $0.05 per share payable on November ~~7, 2022,~~6, 2023, to stockholders of record as of October ~~28, 2022;~~27, 2023; dividends of $2.2 million are scheduled to be paid to stockholders on November ~~7, 2022.~~6, 2023.

Note 2 – Acquisition

On December 1, 2021, the Company completed its acquisition of West Suburban Bancorp, Inc. (“West Suburban”), a bank holding company, and its wholly owned subsidiary, West Suburban Bank, based in Lombard, Illinois, with operations throughout our existing market footprint. ~~This acquisition brought increased scale and new markets to the Company, and provided new product offerings and line of business opportunities.~~ At closing, the Company acquired $2.94 billion of assets, $1.50 billion of loans, $1.07 billion of securities, and $2.69 billion of deposits, net of fair value adjustments. Under the terms of the merger agreement, each outstanding share of West Suburban common stock was exchanged for 42.413 shares of Company common stock, plus $271.15 of cash. This resulted in merger consideration of $295.2 million, based on the closing price of the Company’s common stock on the date of acquisition, which consisted of 15.7 million shares of the Company’s common stock and $100.7 million of cash. Goodwill of $67.9 million associated with the acquisition was recorded by the Company, which was the result of expected synergies, operational efficiencies and other factors.

The acquisition of West Suburban was accounted for as a business combination. We recorded the estimate of fair value based on initial valuations available at December 1, 2021. The determination of estimated fair value required management to make assumptions related to discount rates, expected future cash flows, market conditionscombination, and other future events that are often subjective in nature and may require adjustments. Estimated fair values which are subject to adjustment for up to one year after December 1, 2021 are considered final as of September 30, 2022. Adjustments and reclasses between deferred tax assets and current taxes receivable, which is reported within other

~~Tableof Contents~~

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

assets, were identified during the quarter ended September 30, 2022 based on further analysis after West Suburban Bank tax filings were made. Deferred tax assets increased $3.7 million, which was offset by a decrease in current taxes receivable of $3.9 million, which resulted in an increase to goodwill of $146,000. Nonenone of the $67.9 million of goodwill recorded is expected to be deductible for income tax purposes.

The following table provides the preliminary purchase price allocation as of the December 1, 2021 closing date of the merger for the estimated fair value of the assets acquired and liabilities assumed, as recorded by the Company.

Purchased loans and leases that reflect a more-than-insignificant deterioration of credit from origination are considered purchased credit deteriorated (“PCD”) loans. For PCD loans, the initial estimate of expected credit losses was recognized in the allowance for credit losses (“ACL”) on the date of acquisition using the same methodology as other loans and leases held-for-investment. The following table provides a summary of loans purchased as part of the West Suburban acquisition which were individually evaluated and determined to be PCD loans at acquisition.

Note 3 – Securities

Investment Portfolio Management

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 $4.5 million at September 30, 2022, and $7.1 million at December 31, 2021. FRBC stock was recorded at $14.9 million at September 30, 2022, and $6.2 million at December 31, 2021.

The following tables summarize the amortized cost and fair value of the securities portfolio at September 30, 2022, and December 31, 2021, and the corresponding amounts of gross unrealized gains and losses:

generally guaranteed by the U.S Department of Education (“DOE”) at not less than 97% of the outstanding principal amount of the loans. The guarantee will reduce to 85% if the DOE receives reimbursement requests in excess of 5% of insured loans; reimbursement will drop to 75% if reimbursement requests exceed 9% of insured loans. In addition to the DOE guarantee, total added credit enhancement in the form of overcollateralization and/or subordination amounted to $20.3 million, or 9.29%, of outstanding principal.

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. No credit losses were determined to be present as of September 30, 2022, as there was no credit quality deterioration noted. Therefore, no provision for credit losses on securities was recognized for the third quarter of 2022.

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.

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 September 30, 2023, as there was no credit quality deterioration noted. Therefore, no provision for credit losses on securities was recognized for the third quarter of 2023.

At September 30, 2023, our allowance for credit losses (“ACL”) on loans totaled $51.7 million, and our ACL on unfunded commitments, included in other liabilities, totaled $2.9 million including related purchase accounting adjustments. During the first nine months of 2023, we recorded net provision expense of $8.5 million based on historical loss rate updates driven by higher charge offs in commercial real estate-investor, loan growth of approximately $160.0 million, downward risk rating migration including an increased reserve on loans individually analyzed, and our assessment of estimated future credit losses. The ACL on loans excludes $2.7 million, $4.3 million and $4.4 million of allowance for unfunded commitments as of September 30, 2023, December 31, 2022 and September 30, 2022, respectively, recorded within Other Liabilities. The total ACL on unfunded commitments listed as of September 30, 2023, December 31, 2022, and September 30, 2022 excludes the purchase accounting adjustment of $149,000, $819,000, and $1.0 million, respectively, recorded due to our acquisition of West Suburban, which is also recorded within Other Liabilities, and is being accreted in interest income over the estimated life of the unused commitments.

Generally, the Bank considers a loan to be collateral dependent when, based on current information and events, it is probable that foreclosure will 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 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 $55.8 million and $50.5 million of collateral dependent loans secured by real estate or business assets as of September 30, 2023, and December 31, 2022, respectively.

The following tables present the collateral dependent loans and the related ACL allocated by segment of loans as of September 30, 2023 and December 31, 2022:

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.

~~Credit quality indicators by loan segment and loan origination date at September 30, 2022 were as follows:~~

The Company had ~~$659,000~~$176,000 and ~~$488,000~~$600,000 in residential real estate loans in the process of foreclosure as of September 30, ~~2022,~~2023 and December 31, ~~2021,~~2022, respectively.

~~Troubled debt restructurings~~As of January 1, 2023, the Company prospectively adopted ASU 2022-02, Topic 326 “Troubled Debt Restructuring (“TDRs”) ~~are~~and Vintage Disclosures”, see Note 1. Fifteen loans, ~~for~~totaling $43.0 million in aggregate, were modified which the contractual terms have been modified and both of these conditions exist: (1) there is a concession to the borrower and (2) the borrower is experiencing financial difficulties. Loans are restructured on a case-by-case basis during the loan collection process with modifications generally initiated at the request of the borrower. These modifications may include reduction in interest rates, extension of term, deferrals of principal, and other modifications. The Bank participates in the U.S. Department of the Treasury’s (the “Treasury”) Home Affordable Modification Program (“HAMP”) which gives qualifying homeowners an opportunity to refinance into more affordable monthly payments. Additionally, in accordance with interagency guidance, short-term deferrals granted due to the COVID-19 pandemic were ~~not considered TDRs, if modified prior to January 1, 2022, unless the borrower was~~ experiencing financial difficulty ~~prior to~~during the ~~pandemic.~~

The specific allocation of the allowance for credit losses for TDRs is determined by calculating the present value of the TDR cash flows by discounting the original payment less an assumption for probability of default at the original note’s issue rate, and adding this amount to the present value of collateral less selling costs. If the resulting amount is less than the recorded book value, the Bank either establishes a valuation allowance (i.e., specific reserve) as a component of the allowance for credit losses or charges off the impaired balance if it determines that such amount is a confirmed loss. This method is used consistently for all segments of the portfolio. The allowance for credit losses also includes an allowance based on a loss migration analysis for each loan category on loans and leases that are not individually evaluated for specific impairment. All loans charged-off, including TDRs charged-off, are factored into this calculation by portfolio segment.

nine-month period ending September 30, 2023. There were no TDR loan modifications for the three months ended September 30, 2022, and there were two TDR loan modifications for an aggregate of $39,000 for the nine months ended September 30, 2022. ~~There was no TDR activity for the three and nine months ended September 30, 2021.~~ TDRs ~~are~~were classified as being in default on a case-by-case basis when they ~~fail~~failed to be in compliance with the modified terms. There were no financial difficulty loans modified in payment default as of September 30, 2023 and was no TDR default activity for the ~~periods~~period ended September 30, ~~2022, and September 30, 2021,~~2023, for loans that were restructured within the prior ~~12 month~~12-month period.

The following table presents the amortized costs basis of loans at September 30, 2023 that were both experiencing financial difficulty and modified during the period ended September 30, 2023 by class and by type of modification.

Note 98 – 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 ~~plan~~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

~~Tableof Contents~~

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 ~~stock options and SARs~~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 ~~units~~ 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 Generally, restricted stock and restricted stock units granted under the Plan vest three years from the grant date, but the Compensation Committee of the Company’s Board of Directors has discretionary authority to change some terms including the amount of time until the vest date.

There were 268,160 and 222,464 restricted stock units issued under the 2019 Plan during the nine months ended September 30, 2022 and September 30, 2021, respectively. Compensation expense is recognized over the vesting period of the restricted stock units based on the market value of the award on the issue date. Total compensation cost that has been recorded for the 2019 Plan was $2.2 million in the first nine months of 2022 and $1.2 million for the first nine months ended of 2021.

Note 1110 – Regulatory & 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 September 30, ~~2022,~~2023, the Bank exceeded those thresholds.

At September 30, ~~2022,~~2023, the Bank’s Tier 1 capital leverage ratio was ~~9.24%~~10.43%, ~~a decrease~~an increase of 34111 basis points from December 31, ~~2021, but~~2022, and is above the 8.00% objective. The Bank’s total capital ratio was ~~12.64%~~13.57%, ~~a decrease~~an increase of 82 basis points from December 31, ~~2021, but~~2022, 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 September 30, ~~2022,~~2023 and December 31, ~~2021.~~2022.

In July 2013, the U.S. federal banking authorities issued final rules (the “Basel III Rules”) establishing more stringent regulatory capital requirements for U.S. banking institutions, which went into effect on January 1, 2015. 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, ~~2021,~~2022, under the heading “Supervision and Regulation.”

At September 30, ~~2022~~2023 and December 31, ~~2021,~~2022, the Company, on a consolidated basis, exceeded the minimum thresholds to be considered “well capitalized” under current regulatory defined capital ratios.

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 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 September 30, ~~2022,~~2023, the capital measures of the Company exclude ~~$2.9~~$1.9 million, 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 September 30, ~~2022,~~2023, the Bank had capacity to pay dividends of ~~$17.7~~$70.4 million to the Company without prior regulatory approval. Pursuant to the Basel III rules, ~~that came into effect January 1, 2015, and were fully phased in as of January 1, 2019,~~ 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 1211 – Fair 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.

~~Transfers between levels are deemed to have occurred at~~During the ~~end of the reporting period. At~~nine-month period ended September 30, ~~2022~~2023, $14.9 million of asset-backed securities and ~~2021, there~~$6.8 million of collateralized mortgage obligations were transferred to Level 2 from Level 3. There were no transfers between ~~levels.~~levels at September 30, 2022.

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, 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 ~~impaired~~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 ~~OREO~~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, an impairment loss is recognized.

¹Represents 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 $82.0 million and a valuation allowance of $18.7million resulting in an increase of specific allocations within the allowance for credit losses on loans of $1.0 million for the nine months ended September 30, 2023.

²OREO is measured at fair value, less costs to sell, and had a net carrying amount of $407,000 at September 30, 2023, which is made up of the outstanding balance of $525,000, and a valuation allowance of $118,000.

²OREO is measured at fair value, less costs to sell, and had a net carrying amount of $1.6 million at December 31, 2022, which is made up of the outstanding balance of $2.5 million, net of a purchase accounting adjustment of $131,000 and a valuation allowance of $856,000.

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 September 30, 2023 and December 31, 2022, 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.

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. FHLBC stock is carried at cost and considered a Level 2 fair value. The fair value of loans and leases at September 30, 2022 and December 31, 2021, was 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 1413 – 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 ~~these objectives,~~this objective, the Company primarily uses interest rate swaps as part of its interest rate risk management strategy. ~~Interest rate swaps designated as cash flow hedges involve the receipt of variable-rate amounts from a counterparty in exchange for the Company making fixed-rate payments over the life~~The aggregate fair value of the ~~agreements without exchange~~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 ~~underlying notional amount. In December of 2019, the Company also executed a loan pool~~ hedge of $50 million to convert variable rate loans to a fixed rate index for a five year term. In August of 2022, the Company also executed two loan pool hedges of $100 million each to convert variable rate loans to a fixed rate index for a three year term.

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~~accumulated other comprehensive income and subsequently reclassified into interest ~~income/~~income or interest expense in the same period(s) during which the hedged transaction affects earnings. Amounts

~~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 ~~variable-rate~~fixed-rate borrowings.

Interest rate swaps with notional amounts totaling $300.0 million and $250.0 million as of September 30, 2023 and December 31, 2022, respectively, 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 September 30, 2023 and December 31, 2022, 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 ~~$3.5~~$7.0 million will be reclassified as ~~a decrease~~an increase to interest income and an additional ~~$401,000~~$708,000 will be reclassified as ~~a decrease~~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 September 30, 2023 and December 31, 2022 were $105.6 million and $110.6 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 ~~with financial counterparties~~ are recognized directly in earnings.

At September 30, 2023 and December 31, 2022, the Company had $9.2 million and $11.2 million of cash collateral pledged with two correspondent financial institutions, respectively. The Company held $8.1 million and $5.3 million of cash pledged from one correspondent financial institution to support the interest rate swap activity during the years presented, respectively. No investment securities were required to be pledged to any correspondent financial institution during 2023 through September 30, 2023, or during 2022. 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 September 30, 2023 and December 31, 2022 was $7.6 million and $5.3 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 Fair Values of Derivative Instruments on the Balance Sheet~~

The Company entered into a forward starting interest rate swap on August 18, 2015, with an effective date of June 15, 2017. This transaction had a notional amount totaling $25.8 million as of September 30, 2022, was designated as a cash flow hedge of certain junior subordinated debentures and was determined to be fully effective during the period presented. As such, no amount of ineffectiveness has been included in net income. Therefore, the aggregate fair value of the swap is recorded in 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. The Company expects the hedge to remain fully effective during the remaining term of the swap. The Bank will pay the counterparty a fixed rate and receive a floating rate based on three month LIBOR. The trust preferred securities~~changed from fixed rate to floating rate on June 15, 2017. The cash flow hedge has a maturity date of June 15, 2037.~~

In December 2019, the Company also executed a loan pool hedge of $50.0 million to convert variable rate loans to a fixed rate index for a five year term. This transaction falls under hedge accounting standards and is paired against a pool of the Bank’s LIBOR-based loans. In August 2022, the Company also executed two loan pool hedges of $100.0 million each to convert variable rate loans to a fixed rate index for a three year term. This transaction falls under hedge accounting standards and is paired against a pool of the Bank’s SOFR-based loans. Overall, the new swap only bolsters income in down rate scenarios by a modest degree. We consider the current level of interest rate risk to be moderate but intend to continue looking for market opportunities to hedge further.

The Bank also has interest rate derivative positions to assist with risk management that are not designated as hedging instruments. These derivative positions relate to transactions in which the Bank enters an interest rate swap with a client while at the same time entering into an offsetting interest rate swap with another financial institution.

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 $3.8 million as of September 30, 2023, and $4.1 million as of September 30, ~~2022, and $1.8 million as of September 30, 2021.~~2022. The amount of the ~~gain~~loss reclassified from AOCI to net interest income on the income statement was ~~$15,000 and $40,000~~$3.9 million for the nine months ended September 30, ~~2022~~2023 and $15,000 of gain for the nine months ended September 30, ~~2021, respectively.~~2022.

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.

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

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 September 30, ~~2022,~~2023, and December 31, ~~2021.~~2022.

As of September 30, ~~2022,~~2023, the Company evaluated current market conditions, including any impacts related to ~~COVID-19,~~ market interest rate changes and unused line of credit utilization trends during the ~~third~~second quarter of ~~2022,~~2023, and based on that analysis under the CECL methodology, the Company determined credit losses related to unfunded commitments totaled ~~$4.4~~$2.7 million, excluding a ~~$1.0 million~~$149,000 purchase accounting adjustment on unfunded commitments recorded from our West Suburban acquisition, which is being accreted to interest income over the estimated life of the unused commitments. The resultant ~~increase~~decrease in the ACL for unfunded commitments of ~~$749,000~~$235,000 for the third quarter of ~~2022,~~2023, compared to the prior quarter end, is primarily related to a ~~$973,000 increase in the commercial unfunded commitments funding rate assumptions based on our analysis of the last 12 months of utilization, decreased~~$223,000 decrease by accretion ~~of $224,000~~ to interest income of the purchase accounting ~~adjustment.~~adjustment, as well as adjustments to historical benchmark assumptions, such as the funding rates and the period used to forecast those rates within the ACL calculation, resulting in a $12,000 reduction. 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 ~~Sheet,~~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 and nine months ended September 30, ~~2022,~~2023, compared to the three and nine months ended September 30, ~~2021,~~2022, and our financial condition at September 30, ~~2022,~~2023, compared to December 31, ~~2021.~~2022. 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, ~~2021.~~2022. The results of operations for the three and nine months ended September 30, ~~2022,~~2023, are not necessarily indicative of future results. Dollar amounts presented in the following tables are in thousands, except per share data, and September 30, ~~2022~~2023 and ~~2021~~2022 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 5148 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 September 30, 2023, 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.

Merger with West Suburban Bancorp, Inc.

On December 1, 2021, we completed our merger with West Suburban Bancorp, Inc. (“West Suburban”), the holding company for West Suburban Bank. Under the terms of the merger agreement, each share of West Suburban common stock was converted into 42.413 shares of our common stock and $271.15 in cash. Total cash and stock consideration paid was approximately $295.2 million. With the acquisition of West Suburban, we acquired 34 branches in DuPage, Kane, Kendall and Will counties in Illinois. The transaction is discussed in more detail in Note 2 to our Consolidated Financial Statements included in this ~~report.~~report and in Note 2 of our Annual Report in Form 10-K.

As we continue to consolidate operations, nine branches designated as held for sale with a net book value of $5.8 million are reported within fixed assets at September 30, 2022. During the nine months ended September 30, 2022, we sold nine branches, resulting in $977,000 of net gains on sale, after closing costs.

~~COVID-19 Update~~Recent Banking Events

~~Our historically careful underwriting practices~~There were three significant bank failures in the first five months of 2023, primarily due to the failed banks’ lack of liquidity as depositors sought to withdraw their deposits. Due to rising interest rates, the failed banks were unable to sell investment securities held to meet liquidity needs without realizing substantial losses. As a result of the bank closures during 2023 and ~~diverse loan portfolio has helped~~in an effort to strengthen public confidence in the banking system and protect depositors, regulators announced that any losses to the Deposit Insurance Fund to support uninsured depositors will be recovered by a special assessment on banks, as required by law, which could increase the cost of our FDIC insurance assessment. Additionally, the Federal Reserve announced the creation of a new Bank Term Funding Program in an effort to minimize the ~~adverse~~need for banks to sell securities at a loss in times of stress. We have access but have not received or requested funds from this Program and, though we do have access to the Federal Reserve Discount Window, we have not accessed these funds and have an unused capacity of $18.7 million at September 30, 2023. The future impact of ~~the pandemic~~these failures on the ~~Company. In addition,~~economy, financial institutions and their depositors, as well as any governmental regulatory responses or actions resulting from the combination of the vaccine rollout, government stimulus payments, and reduced spending during the pandemic are likely contributing factors mitigating the impact of the pandemic on our business, financial condition, results of operations, and our customers as of September 30, 2022. While the vaccine remains readily available, the longer term macro-economic effects on global supply chains, inflation, labor shortages and wage increases continue to impact many industries. The ultimate extent of the impact of the COVID-19 pandemic on our business, financial condition and results of operations is currently uncertain and will depend on various developments and other factors, including a resurgence of COVID-19 cases, hospitalizations and deaths leading to additional government imposed restrictions; refusals to receive the vaccine or any boosters along with concerns related to new strains of the virus; supply chain issues remaining unresolved longer than anticipated; labor shortages and wage increases continuing to impact many industries; consumer confidence and spending falls; and rising geopolitical tensions. Given the ongoing and dynamic nature of the circumstances surrounding the pandemic, itsame, is difficult to predict ~~its future adverse financial impact to the Company.~~

~~Tableof Contents~~

~~Results of Operation and Financial Condition~~at this time.

We continue to monitor the impact of the COVID-19 pandemic on our results of operations and financial condition. For the year ended December 31, 2020, we determined it prudent to increase our allowance for credit losses to $33.9 million, driven by both our adoption of the Current Expected Credit Losses (“CECL”) methodology and the expected impact of the COVID-19 pandemic and market interest rate reductions in anticipation of continued market risk and uncertainty. In 2021, due to the lack of significant net charge-offs projected with the 2020 forecast, and a more favorable forecast for the estimated life of loans, we reversed $9.5 million of our legacy allowance for credit losses, but recorded $12.1 million of Day One credit marks to the allowance for credit losses, as well as $12.2 million of Day Two adjustments on non-purchase credit deteriorated life of loan loss estimates, each stemming from the West Suburban acquisition. During the first nine months of 2022, we recorded $5.2 million of provision for credit losses on loans primarily due to loan growth as well as our assessment of loan metrics and nonperforming loan trends. In addition, we also recorded a reduction of $126,000 in our allowance for credit losses on unfunded commitments, primarily due to a review of credit line utilization rates. These adjustments resulted in a net provision for credit losses expense of $5.1 million for the September 30, 2022 year to date period.

We also adjust our investment securities portfolio to fair value each period end and review for any impairment that would require a provision for credit losses. At this time, we have determined there is no need for a provision for credit losses related to our investment securities portfolio. Because of changing economic and market conditions affecting issuers, we may be required to recognize impairments in the future on the securities we hold as well as experience reductions in other comprehensive income. We cannot currently determine the ultimate impact of the pandemic on the long-term value of our portfolio.

As of September 30, 2022 and December 31, 2021, we had $86.5 million and $86.3 million of goodwill, respectively. This reflected a $146,000 increase from the prior quarter and prior year-end as a deferred tax asset and current taxes receivable analysis was performed after the filing of West Suburban Bank related tax returns, with the resultant reclassifications impacting goodwill. At November 30, 2021, we performed our recurring annual review for any goodwill impairment. We determined no goodwill impairment existed, however, further deterioration in market conditions related to the general economy, financial markets, and the associated impacts on our customers, employees and vendors, among other factors, could significantly impact the impairment analysis and may result in future goodwill impairment charges that, if incurred, could have a material adverse effect on our results of operations and financial condition.

~~Lending Operations and Accommodations to Borrowers~~

To more fully support our customers during the pandemic, we established client assistance programs, including offering commercial, consumer, and mortgage loan payment deferrals for certain clients. During 2020 and 2021, we executed 509 of these deferrals on loan balances of $242.7 million. As of September 30, 2022, all COVID-related loan deferrals had resumed payments or paid off.

During 2020 and 2021, as part of the SBA Paycheck Protection Program (“PPP”), we processed 1,320 PPP loan applications, representing a total of $199.0 million, and we acquired $20.8 million PPP loans from our acquisition of West Suburban. We started the application process for loan forgiveness for PPP loans in October 2020, and we continued to receive funds for forgiven loans from both the first and second round of PPP loans through September 2022. As of September 30, 2022, we had 19 loans, which totaled $2.4 million, still outstanding under the PPP program. We expect the application process for loan forgiveness to continue through the fourth quarter of 2022, with funds to be received from the SBA for the forgiven loans through the remainder of 2022.

~~Capital and Liquidity~~

As of September 30, 2022, 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.

We believe there could be potential stresses on liquidity management as a result of the COVID-19 pandemic. For instance, as customers manage their own liquidity stress, we could experience an increase in the utilization of existing lines of credit. However, to date, due in part to federal government stimulus funds received by our customers, as well as a higher volume of loan paydowns than periods prior to COVID-19, our liquidity has increased.

Financial Overview

Net income for the third quarter of ~~2022~~2023 was ~~$19.5~~$24.3 million, or ~~$0.43~~$0.54 per diluted share, compared to ~~$8.4~~$19.5 million, or ~~$0.29~~$0.43 per diluted share, for the third quarter of ~~2021.~~2022. The increase was primarily due to growth in our ~~acquisition of West Suburban,~~loan portfolio and higher loan and security yields, partially offset by increased funding costs and increased other short-term borrowing, which resulted in growth in net interest income. Noninterest income ~~and noninterest income, partially offset by higher noninterest expense, which included $1.1 million in acquisition-related~~

~~Tableof Contents~~

~~costs net of losses on sales of branches~~decreased in the third quarter of ~~2022.~~2023, compared to the like quarter of 2022, as a result of net losses on security sales and a reduction in mortgage banking revenues. An increase was also noted in noninterest expense for the current quarter, primarily due to higher salaries and employee benefits and $629,000 of liquidation and deconversion costs incurred in the third quarter of 2023 related to the 2022 sale of our Visa credit card portfolio. Also contributing to the increase in net income in the third quarter of 2023, compared to the third quarter of 2022, were acquisition costs, net of gains on branch sales, of $2.0 million incurred in the prior year like quarter, compared to no acquisition related costs or branch sales in the third quarter of 2023. Adjusted net income, a non-GAAP financial measure that excludes ~~merger-related costs, net of gains/(losses) on branch sales, and gains on the sale of a~~ Visa ~~credit card~~ portfolio and a land trust portfolio gains on sale, Visa portfolio liquidation and deconversion costs, and any merger related costs, as applicable, was $24.8 million for the third quarter of 2023, compared to $25.6 million for the second quarter of 2023, and $19.6 million for the third quarter of 2022. Adjusted net income was $73.8 million for the nine months ended September 30, 2023, compared to $49.4 million for the nine months ended September 30, 2022. See the discussion entitled “Non-GAAP Financial Measures” on page ~~42,~~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 September 30, ~~2022,~~2023, compared to the like period ended September 30, ~~2021:~~2022:

●

Net interest and dividend income was $63.0 million for the third quarter of 2023, compared to $55.6 million for the third quarter of ~~2022, compared to $22.6 million for the third quarter of 2021.~~2022. Growth in interest and dividend income in the third quarter of ~~2022~~2023 was primarily due to ~~our acquisition of West Suburban resulting in additional~~ loan growth and ~~securities income.~~higher yields on loans, partially offset by higher funding and borrowing costs, as well as increased other short-term borrowings.

●

We recorded a net provision for credit losses of ~~$4.5~~$3.0 million in the third quarter of ~~2022,~~2023, driven by a ~~$3.5~~$3.0 million increase in the allowance for credit losses on loans ~~due to~~based on increased historical loss rates, loan growth, ~~in the portfolio, coupled with an increase~~our assessment of ~~$973,000~~nonperforming loan metrics and trends, and estimated future credit losses, net of a reversal of $12,000 in our allowance for unfunded ~~commitments.~~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 ~~$1.5~~net provision for credit loss of $4.5 million ~~release of provision expense in the third quarter of 2021.~~

●

Noninterest income was $11.5 million for the third quarter of 2022, compared to $9.3 million for the third quarter of 2021, an increase of $2.2 million, or 23.1%. Contributing to the increase was growth in service charges on deposits and card related income resulting primarily from the West Suburban acquisition and resultant additional fee income. These increases were partially offset by a decrease of $1.7 million of net gain on sale of mortgage loans from $2.2 million in the third quarter 2021 to $449,000 in the third quarter of 2022.

●

Noninterest income was $9.9 million for the third quarter of 2023, compared to $11.5 million for the third quarter of 2022. Contributing to the decrease were security losses of $924,000 due to strategic sales in the third quarter of 2023, compared to losses on the call of securities of $1,000 in the third quarter of 2022. Also contributing to the reduction in noninterest income was a $1.1 million decrease in other income, primarily due to the gain on sale of both our Visa credit card portfolio and the land trust portfolio in 2022. These decreases were partially offset by an increase of $195,000 in wealth management income and a $773,000 increase in the cash surrender value of BOLI.

Results of Operations

Overview

Three months ended September 30, ~~2022~~2023 and ~~2021~~2022

Our income before taxes was $32.5 million in the third quarter of 2023 compared to $26.6 million in the third quarter of ~~2022 compared to $11.3 million in the third quarter of 2021.~~2022. This increase in pretax income was primarily due to a ~~$33.0~~$7.5 million increase in net interest and dividend income, and a ~~$2.2~~$1.5 million ~~increase~~decrease in provision for credit losses. Income before taxes was negatively impacted by a $1.6 million decrease in noninterest income, primarily due to ~~the addition~~$924,000 of ~~West Suburban loans, securities~~security losses and ~~fee~~a $1.1 million decrease in other income in the third quarter of ~~2022. These increases were partially offset by~~2023, as well as a ~~$13.9~~$1.4 million increase in noninterest expense, primarily due to an increase in salaries and employee benefits, occupancy, furniture and equipment expense, computer and data processing expense, other expense, and amortization of core deposit intangible. The majority of these increases were due to the inclusion of operating costs of the legacy West Suburban staff and branches, as well as $650,000 of West Suburban acquisition-related costs inexpense. Our net income was $24.3 million, or $0.54 per diluted share, for the third quarter of ~~2022, primarily within management and consulting and other expenses. Our~~2023, compared to net income ~~was~~of $19.5 million, or $0.43 per diluted share, for the third quarter of 2022. 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 $63.0 million in the third quarter of 2023, compared to $55.6 million in the third quarter of 2022. The $7.4 million increase was primarily driven by significant growth in our loan portfolio as well as the effect of higher market interest rates on our loan portfolios. Higher interest income was partially offset by an increase in interest expense in the third quarter of 2023, compared to the third quarter of 2022, primarily due to a rise in deposit interest rates, and an increase in other short-term borrowing expense due to additional FHLB advances. As of June 30, 2023, we redeemed the $45.0 million senior debt issuance that was due in 2026, which resulted in no senior debt interest expense recorded for the third quarter of 2023.

Nine months ended September 30, 2023 and 2022

Our income before taxes was $99.5 million for the nine months ended September 30, 2023 compared to $59.7 million for the nine months ended September 30, 2022. This increase in pretax income was primarily due to a $48.6 million increase in net interest and dividend income and a $3.3 million decrease in noninterest expenses. These changes were partially offset by a $3.5 million increase in provision for credit losses, and a $8.7 million decrease in noninterest income, mainly due to $4.1 million of security losses recorded in the first nine months of 2023 and a $4.5 million decrease in mortgage banking revenues. Our net income was $73.5 million, or $1.62 per diluted share, for the nine months ended September 30, 2023, compared to net income of ~~$8.4~~$43.8 million, or ~~$0.29~~$0.97 per diluted share, for the ~~third quarter~~same period of ~~2021.~~2022.

Net interest and dividend income was $190.7 million for the nine months ended September 30, 2023, compared to $142.1 million for the same period of 2022. The $48.6 million increase was primarily driven by significant growth in our loan portfolio as well as the effect of higher market interest rates on our loan and securities portfolios. Higher interest and dividend income was partially offset by an increase in interest expense in the first nine months of 2023, compared to the first nine months of 2022, primarily due to a rise in deposit interest rates, an increase in other short-term borrowing expense due to FHLB advances, and an increase in the rate paid on our senior notes. The senior notes redeemed on June 30, 2023 had an effective cost of 10.95% for the nine months ending September 30, 2023.

Table of Contents

Net interest and dividend income was $55.6 million in the third quarter of 2022, compared to $22.6 million in the third quarter of 2021. The $33.0 million increase was primarily driven by growth in most interest and dividend income categories due to West Suburban related loan and securities income being reflected. In addition we experienced an increase in interest expense in the third quarter of 2022, compared to the third quarter of 2021, primarily due to a rise in deposit interest rates and increased balances from West Suburban, an increase in other short-term borrowings due to an FHLB advance, and an increase in the rate paid on our senior notes during the third quarter of 2022, as the interest rate payable on these notes became floating as of January 1, 2022, at three month LIBOR plus 385 basis points, compared to the prior 5.75% fixed rate.

Average loans, including loans held for sale, increased $1.86 billion in the third quarter of 2022, compared to the third quarter of 2021, primarily from $1.50 billion of average loans acquired in our acquisition of West Suburban. Also contributing to the increase was $244.3 million in average loan growth during the third quarter of 2022, less PPP loans forgiven or repaid and loan paydowns.

~~Nine months ended September 30, 2022 and 2021~~

Our income before taxes was $59.7 million for the nine months ended September 30, 2022 compared to $39.4 million for the nine months ended September 30, 2021. This increase in pretax income was primarily due to a $74.0 million increase in interest and dividend income, and a $5.6 million increase in noninterest income, as West Suburban loan, security and fee income are included in the nine months ended September 30, 2022. These increases were partially offset by a $46.2 million increase in noninterest expense, primarily due to an increase in salaries and employee benefits, occupancy, furniture and equipment expense, computer and data processing expense, other expense, and amortization of core deposit intangible. The majority of these increases were due to the inclusion of operating costs of the legacy West Suburban staff and branches, as well as $9.5 million of West Suburban acquisition-related costs in the first nine months of 2022, primarily within computer and data processing. Our net income was $43.8 million, or $0.97 per diluted share, for the nine months ended September 30, 2022, compared to net income of $29.1 million, or $0.99 per diluted share, for the same period of 2021.

Net interest and dividend income was $142.1 million for the nine months ended September 30, 2022, compared to $68.1 million for the same period of 2021. The $74.0 million increase was primarily driven by growth in most interest and dividend income categories due to West Suburban related loan and securities income being reflected. This increase was partially offset by a $402,000 increase in interest expense for the nine months ended September 30, 2022, compared to the same period of 2021, primarily due to three full periods of interest expense on the April 2021 issuance of subordinated debt in 2022, as well as higher average balances of deposits from the West Suburban acquisition, partially offset by a decrease in outstanding balances of notes payable and a decrease in the rate paid on our senior notes during 2022, as the interest rate payable on these notes became floating as of January 1, 2022, at three month LIBOR plus 385 basis points, compared to the prior 5.75% fixed rate.

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 September 30, ~~2022~~2023 and ~~2021~~2022

~~Our net~~The increased yield of 10 basis points on interest earning assets compared to the linked period was driven by higher yields on loan originations than those in the previous period as well as repricing within the existing variable rate portfolios for securities available-for-sale and ~~dividend income increased~~loans. 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 136 basis points on interest earning assets was driven by ~~$33.0 million~~significant increases to ~~$55.6 million, for~~benchmark interest rates as well as strong loan growth throughout the period, specifically within the leases, commercial real estate and multifamily portfolios, as these loan segments generally produce the greatest yield. The increases in benchmark interest rates impacted yields on the securities portfolio through the inverse relationship between interest rates and market value coupled with maturities and strategic sales of lower yielding assets, as we work to increase the weighted average yield in the portfolio.

Average balances of interest-bearing deposit accounts have decreased steadily since the third quarter of 2022 ~~from $22.6 million for~~through the third quarter of ~~2021. This increase was primarily attributable~~2023, from $3.23 billion to ~~a $33.2 million~~$2.79 billion, with decreases reflected in all deposit categories excluding time deposits. We have continued to control the cost of funds over the periods reflected, with the rate of overall interest-bearing deposits increasing to 65 basis points for the quarter ended September 30, 2023, from 40 basis points for the quarter ended June 30, 2023, and from nine basis points for the quarter ended September 30, 2022. A 32 basis point increase in ~~total interest~~the cost of money market funds for the quarter ended September 30, 2023 compared to prior linked quarter, and ~~dividend income~~a 91 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 September 30, 2023 increased by 63 basis points and 140 basis points in the quarter over linked quarter and year over year quarters, respectively, primarily due to CD rate specials we offered.

Borrowing costs decreased in the third quarter of 2023 compared to the second quarter of 2023, primarily due to the ~~acquisition~~redemption of ~~West Suburban in December 2021. In addition we experienced~~the senior notes as of June 30, 2023, partially offset by an increase in average short-term borrowings of $24.6 million stemming from increased average FHLB advances over the prior quarter. The increase of $421.7 million year over year of average FHLB advances was based on daily liquidity needs. Subordinated and junior subordinated debt interest expense were essentially flat over each of the periods presented. We redeemed all of the $45.0 million senior notes, net of deferred issuance costs, on June 30, 2023, resulting in senior notes having no balance or related interest expense in the third quarter of ~~2022, compared to~~2023. In February 2023, we paid off the ~~third quarter~~remaining balance of ~~2021, primarily due to increased balances from West Suburban, increased~~$9.0 million on the original $20.0 million term note issued in 2020, resulting in notes payable and other ~~short-term~~ borrowings expense due to an FHLB advance, and an increase in the rate paid on our senior notes during 2022, as the interest rate payable on these notes became floating as of January 1, 2022, at three month LIBOR plus 385 basis points, compared to the prior 5.75% fixed rate.having no balance after that time.

~~Average earning assets~~Our net interest margin (GAAP) increased three basis points to 4.64% for the third quarter of ~~2022 totaled $5.61 billion, a decrease of $141.5 million, or 2.5%,~~2023 compared to 4.61% for the second quarter of ~~2022,~~2023, and ~~an increase of $2.52 billion, or 81.7%,~~increased 71 basis points compared to 3.93% for the third quarter of ~~2021. Average~~2022. Our net interest ~~earning deposits with~~margin (TE) increased two basis points to 4.66% for the third quarter of 2023, compared to 4.64% for the second quarter of 2023, and increased 70 basis points compared to 3.96% for the third quarter of 2022. The increase in the current quarter, compared to the prior quarter, is primarily due to the growth in loan interest income due to the rising interest rate environment, and a decrease in borrowing interest expense due to the redemption of the senior notes in June 2023. The increase in the current quarter, compared to the prior year like quarter, is primarily due to an increase in market interest rates, and the related rate resets on loans and securities during the past year, as well as continuing loan growth relative to a more modest increase in costs of interest-bearing liabilities. See the discussion entitled “Non-GAAP Financial Measures” and the tables on page 45 that provide a reconciliation of each non-GAAP measure to the most comparable GAAP equivalent.

~~financial institutions totaled $131.3 million for the third quarter of~~Nine months ended September 30, 2023 and 2022 a decrease of $295.6 million, compared to the second quarter of 2022, and a decrease of $392.3 million compared to the third quarter of 2021. The yield on average interest earning deposits was 200 basis points for the third quarter of 2022, an increase of 127 basis points from the second quarter of 2022, and an increase of 185 basis points from the third quarter of 2021. Interest income on securities increased year over year, primarily due to growth in volumes and higher interest rates. Total average securities for the third quarter of 2022 decreased $88.8 million from the second quarter of 2022, and increased $1.04 billion from the third quarter of 2021. The increase in our average securities year over year was primarily due to the $1.07 billion in securities acquired in our acquisition of West Suburban. The yield on average securities increased to 2.52% for the third quarter of 2022, compared to 1.89% for the second quarter of 2022 and increased from 2.07% for the third quarter of 2021. Total average loans, including loans held-for-sale, totaled $3.75 billion in the third quarter of 2022, an increase of $244.3 million from the second quarter of 2022, and an increase of $1.86 billion from the third quarter of 2021. The rise in average loan balances year over year was primarily due to the $1.50 billion loan portfolio acquired in our acquisition of West Suburban, as well as loan growth of $244.3 million in the third quarter of 2022. This rise in loan volumes resulted in an increase in loan interest and fee income of $25.3 million in the year over year period. For the third quarter of 2022, the yield on average loans increased to 4.93%, compared to 4.37% for the second quarter of 2022, and 4.48% for the third quarter of 2021.

Average interest bearing liabilities decreased $113.1 million, or 3.2%, in the third quarter of 2022, compared to the second quarter of 2022, and increased $1.54 billion compared to the third quarter of 2021. The year over year increase of 187 basis points on interest earning assets was driven by significant increases to benchmark interest rates as well as strong loan growth throughout the period, specifically within the leases, commercial real estate-investor, construction and multi-family portfolios. The increases in benchmark interest rates impacted yields on the securities portfolio through the inverse relationship between interest rates and market value coupled with maturities and strategic sales of lower yielding assets and timely purchase of higher yielding securities as we work to increase the weighted average yield in the portfolio. Average securities available-for-sale decreased $367.0 million for the nine months ended September 30, 2023, compared to the nine months ended September 30, 2022, due to paydowns, changes in market value, and strategic sales. Due to market interest rate increases year over year, securities available-for-sale interest income was $34.7 million for the nine months ended September 30, 2023, compared to $26.1 million for the like 2022 period, reflecting an increase in yield of 134 basis points. Average loans, including loans held for sale, increased $438.0 million in the nine months ended September 30, 2023, compared to the nine months ended September 30, 2022, primarily driven by ~~a $1.55 billion~~the growth in leases, commercial real estate-investor, construction, and multi-family portfolios. Growth in the loan portfolio, as well as the rising interest rate environment, resulted in $181.5 million of loan interest income in the nine months ended September 30, 2023, compared to $121.3 million in the like 2022 period, reflecting an increase in ~~interest bearing~~yield of 152 basis points.

Average balances of interest-bearing deposit accounts have decreased steadily since September 30, 2022 through the nine months ended September 30, 2023, from $3.32 billion to $2.89 billion, with such decreases reflected in all categories. We have continued to control the cost of funds over the periods reflected, with the rate of overall interest-bearing deposits increasing by 35 basis points to 43 basis points from eight basis points as of September 30, 2022. A 61 basis point increase in the cost of money market funds as of September 30, 2023, compared to September 30, 2022, was due to select deposit account exception pricing and drove a significant portion of the overall increase. Interest expense paid on time deposits also contributed to the increased cost of deposits year over year, as the cost of average time deposits increased 89 basis points to 114 basis points for the nine months ended September 30, 2023, compared to 25 basis points for the nine months ended September 30, 2022, primarily due to ~~our acquisition~~CD rate specials we offered.

Borrowing costs increased in the nine months ended September 30, 2023 primarily due to the increase in short term borrowings from higher average FHLB advance growth of ~~West Suburban,~~$342.5 million since the nine months ended September 30, 2022, based on daily liquidity needs. Subordinated and junior subordinated debt interest expense remained flat over the periods presented. Senior notes interest expense had the most significant interest expense increase, as ~~well~~this issuance referenced three-month LIBOR, and rising market interest rates resulted in a 557 basis point increase to 10.95%, from 5.38% for the nine months ended September 30, 2022. We redeemed these notes on June 30, 2023, which contributed to the significant basis point increase due to the $362,000 in deferred issuance costs that were recognized as ~~continued deposit activity~~interest expense due to the early redemption. In the first quarter of ~~our legacy customers, offset by a $12.6~~2023, we paid off the remaining balance of $9.0 million ~~decrease~~on the original $20.0 million term note issued in ~~securities sold under repurchase agreements and a $10.2 million decrease in~~2020, recorded within notes payable and other borrowings. The linked quarter decrease was primarily the result of maturing higher cost time deposits and declines in money market accounts. The cost of interest bearing liabilities for the third quarter of 2022 increased four basis points from the linked period, and decreased 18 basis points from the third quarter of 2021. Growth in our average noninterest bearing demand deposits of $1.06 billion in the year over year period has assisted us in controlling our cost of funds stemming from average interest bearing deposits and borrowings, which totaled 0.18% for the third quarter of 2022, 0.15% for the second quarter of 2022, and 0.30% for the third quarter of 2021.

Due to the significant increase in interest earning deposits with financial institutions in 2020 and 2021 stemming from federal stimulus funds received and PPP loan forgiveness, we had no average other short-term borrowings in the first and second quarters of 2022 or the third quarter of 2021, which typically consist of FHLBC advances. In the third quarter of 2022, we had an average other short-term borrowing balance of $5.4 million due to a $25.0 million FHLB advance. As of September 30, 2022, notes payable and other borrowings had an average balance of $11.0 million, which consists of $10.0 million outstanding on a term note with a correspondent bank originated in the first quarter of 2020.

Our net interest margin (GAAP) increased 77135 basis points to ~~3.93%~~4.66% for the ~~third quarter of 2022,~~nine months ended September 30, 2023, compared to ~~3.16%~~3.31% for the ~~second quarter of 2022, and increased 102 basis points compared to 2.91% for the third quarter of 2021.~~nine months ended September 30, 2022. Our net interest margin (TE) increased 78135 basis points to ~~3.96%~~4.68% for the ~~third quarter of 2022,~~nine months ended September 30, 2023, compared to ~~3.18%~~3.33% for the ~~second quarter of 2022, and increased 101 basis points compared to 2.95% for the third quarter of 2021.~~nine months ended September 30, 2022. The increase in the ~~year over year was due primarily~~current period, compared to the ~~increasing~~prior year like period, is primarily due to an increase in market interest rates, ~~over the majority of the past twelve months,~~and the related rate resets on loans and securities during the past year, ~~and~~as well as continuing loan growth relative to a more modest increase in the ~~elevated liquidity on our balance sheet.~~ cost of interest-bearing liabilities.

We continue to observe competitive pressure to maintain reduced interest rates on loans retained at renewal. While our loan prices are targeted to achieve certain returns on equity, significant competition for commercial and industrial loans as well as commercial real estate loans has put pressure on loan yields, and our stringent underwriting standards limit our ability to make higher-yielding loans.

~~Nine months ended September 30, 2022 and 2021~~

Our net interest and dividend income increased by $74.0 million, to $142.1 million for the nine months ended September 30, 2022, compared to $68.1 million for the nine months ended September 30, 2021. This increase was attributable to a $74.4 million increase in total interest income primarily from the acquisition of West Suburban as well as general loan growth, partially offset by a $402,000 increase in interest expense for the nine months ended September 30, 2022, compared to the nine months ended September 30, 2021. Increased balances on interest earning assets related to the West Suburban acquisition drove the increase in net interest income, along with increased yields on earning assets and the reduction in the cost of interest bearing deposits, despite the increased average balance of subordinated debt.

Average earning assets for the nine months ended September 30, 2022 were $5.74 billion, an increase of $2.72 billion, or 90.0%, compared to the nine months ended September 30, 2021. The yield on average earning assets for the nine months ended September 30, 2022 was 3.49%, compared to 3.34% for the nine months ended September 30, 2021. Total average loans, including loans held-for-sale,

totaled $3.56 billion for the nine months ended September 30, 2022, an increase of $1.61 billion, compared to the nine months ended September 30, 2021. The increase in average loan balances, coupled with increases in market interest rates, resulted in a $56.9 million increase in loan interest income for the nine months ended September 30, 2022, compared to the like period in 2021. For the nine months ended September 30, 2022, yields on average securities decreased by 28 basis points and yields on average loans increased by 13 basis points, each as compared to the nine months ended September 30, 2021, due primarily to the addition of the lower yielding legacy West Suburban securities and loan portfolios in late 2021, as well as the timing of rate resets on loans and securities as interest rates began to rise in 2022, compared to 2021. Average interest earning deposits with financial institutions decreased $65.6 million in the nine months ended September 30, 2022, compared to the prior year like period driven primarily by the acquisition of West Suburban, as well as the use of cash for loan growth and the decrease in customer deposits.

Average interest bearing liabilities increased $1.65 billion, or 88.8%, in the nine months ended September 30, 2022, compared to the nine months ended September 30, 2021. The increase was primarily due to the acquisition of West Suburban in late 2021 resulting in an increase of $2.27 billion of interest earning deposits. In addition, average subordinated debt increased $20.6 million, due to the $60.0 million subordinated note issuance on April 6, 2021, as discussed below. Partially offsetting this increase was a $7.9 million decrease in average notes payable and other borrowings. Average noninterest bearing deposits increased $1.11 billion in the nine months ended September 30, 2022 compared to the nine months ended September 30, 2021, due to the acquisition of West Suburban, as well as remaining federal stimulus funds received from our depositors. The cost of interest bearing liabilities decreased 20 basis points, to 25 basis points, for the nine months ended September 30, 2022, from 45 basis points for the nine months ended September 30, 2021.

In the second quarter of 2021, we entered into Subordinated Note Purchase Agreements with certain qualified institutional buyers pursuant to which we sold and 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 are intended to be used for general corporate purposes, which may include, without limitation, the redemption of existing senior debt, common stock repurchases and strategic acquisitions. 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.

Our net interest margin (GAAP) for the nine months ended September 30, 2022 was 3.31% compared to 3.02% for the nine months ended September 30, 2021, reflecting an increase of 29 basis points. Our net interest margin (TE) for the nine months ended September 30, 2022 was 3.33% compared to 3.06% for the nine months ended September 30, 2021, an increase of 27 basis points. The increase in net interest margin for the nine months ended September 30, 2022, compared to the nine months ended September 30, 2021, was primarily due to the market interest rate increases in 2022, as well as full periods reflecting West Suburban loan and securities income. These increases to the net interest margin were partially offset by reductions in rates paid on deposits, and growth in noninterest bearing deposits, which drove down our overall cost of funds.

The following tables set forth certain information relating to our average consolidated balance ~~sheet~~sheets and reflect the yield on average earning assets and cost of average ~~interest bearing~~interest-bearing liabilities for the periods indicated. These yields reflect the related interest, on an annualized basis, divided by the average balance of assets or liabilities over the applicable period. Average balances are derived from daily balances. For purposes of discussion, net interest income and net interest income to total earning assets in the following tables have been adjusted to a non-GAAP TE basis using a marginal rate of 21% in ~~2022~~2023 and ~~2021~~2022 to compare returns more appropriately on tax-exempt loans and securities to other earning assets.

Reconciliation of Tax-Equivalent Non-GAAP Financial Measures

Net interest and dividend income (TE) and net interest income (TE) to average interest earning assets are non-GAAP measures that have been adjusted on a TE basis using a marginal rate of 21% for ~~2022~~2023 and ~~2021~~2022 to compare returns more appropriately on tax-exempt loans and securities to other earning assets.

Noninterest income increased $2.3 million, or 24.8%, in the third quarter of 2022, compared to the second quarter of 2022, and increased $2.2 million, or 23.1%, compared to the third quarter of 2021. The increase from the second quarter was primarily driven by $1.1 million of growth in residential mortgage banking revenue that is attributable to an increase in mark to market gain on MSRs of $466,000, as

~~well as a $449,000 net gain on~~Noninterest income increased $1.7 million, or 20.1%, in the ~~sale~~third quarter of ~~mortgage loans,~~2023, compared to ~~a net loss of $262,000 on the sale of mortgage loans in~~ the second quarter of 2023, and decreased $1.6 million, or 14.1%, compared to the third quarter of 2022. The ~~variance in mortgage banking is derived~~increase from ~~the changing rate environment experienced during the second and third quarters and the resultant negative impact on interest rate lock commitments during~~ the second quarter of 2023 was primarily driven by a $204,000 increase in residential mortgage banking revenue, a $623,000 decrease in securities losses, net, based on strategic sales, a $501,000 increase in the cash surrender value of BOLI, and a $251,000 increase in other income primarily due to contract incentives achieved on brokerage activities, as well as ~~further increases~~various recoveries on prior year sold mortgage claims.

The decrease in noninterest income of $1.6 million in the ~~fair value~~third quarter of 2023, compared to the third quarter of 2022, is primarily due to an increase in security losses, net, of $923,000 on strategic sales for the quarter ended September 30, 2023, a decrease of $267,000 on mortgage servicing rights ~~during the third quarter. Increases were also noted in service charges on deposits of $333,000,~~mark to market gains, and a $1.1 million decrease in other income ~~of $1.2 million primarily~~ due to a $743,000 pretax gain on a Visa credit card portfolio sale and a $180,000 pretax gain on the sale of a land trust portfolio ~~as compared to the linked quarter. These increases in noninterest income~~recorded in the third quarter of ~~2022, compared to the second quarter of 2022,~~2022. These decreases were partially offset by a ~~$226,000 decrease in wealth management fees, and a $312,000 decrease in card related income.~~

~~The~~$773,000 increase in noninterest income of $2.2 million in the third quarter of 2022, compared to the third quarter of 2021, is primarily due to an increase of $1.3 million in services charges of deposits, an increase of $1.0 million of card related income, and gains on the sale of the Visa credit card portfolio and the land trust portfolio reported in other income. These gains were partially offset by a $1.1 million decline in residential mortgage banking revenue due to increases in interest rates effecting the mortgage banking volumes and related derivative, offset by an increase in the fair value of mortgage servicing rights, and a $260,000 decline in the cash surrender value of ~~BOLI.~~BOLI due to market interest rate changes.

Noninterest expense for the third quarter of ~~2022 decreased $1.3~~2023 increased $2.6 million, or ~~3.4%~~7.4%, compared to the second quarter of ~~2022,~~2023, and increased ~~$13.9~~$1.4 million, or ~~62.6%~~4.0%, compared to the third quarter of ~~2021.~~2022. The ~~decrease~~increase in the third quarter of ~~2022~~2023 compared to the second quarter of 2023 was ~~primarily~~ attributable to $650,000 of West Suburban acquisition-related costs for the third quarter of 2022 compared to $3.3 million for the second quarter of 2022. Acquisition-related costs in the third quarter of 2022 included $90,000 in data processing expense, compared to $1.7 million in the second quarter of 2022, primarily due to acquisition-related core system conversion costs. Partially offsetting the decrease in noninterest expense was an increase in occupancy, furniture and equipment costs of $1.1 million in the third quarter of 2022, compared to the prior quarter, due to net losses on branch sales during the quarter. Finally, our card related expense increased in the third quarter of 2022, compared to the second quarter, due to growth in customer transactions and related volume charges.
~~The year over year increase of $13.9 million in noninterest expense is primarily attributable to an $8.0~~a $1.3 million increase in salaries and employee benefits, ~~a $1.7 million~~primarily due to an increase in ~~occupancy, furniture~~salaries and ~~equipment,~~the officer incentive accrual. Also contributing to the increase in the third quarter of 2023 was a ~~$1.1 million~~$632,000 increase in computer and data processing ~~expense,~~costs as the second quarter reflects software contract incentives, and a ~~$1.2 million~~$787,000 increase in other ~~expense. Officers incentive compensation increased $1.6 million~~expenses primarily due to $629,000 of liquidation costs recorded from the September 2023 Visa credit card portfolio deconversion, which was sold in the third quarter of 2022 ~~compared~~and we continued to service through the third quarter of ~~2021, as incentive accruals increased~~2023. Partially offsetting the increase in ~~the current year due to the acquisition of West Suburban, as well as growth in our commercial lending team. Employee benefits~~noninterest expense ~~increased $1.4 million~~ in the third quarter of 2022, compared to the third quarter of 2021, due to increases stemming from additional employees from our acquisition of West Suburban. The increase in occupancy, furniture and equipment expense year over year was due to the addition of 34 West Suburban branches in late 2021. The $1.1

of 2023 was a $186,000 decrease in legal fees, as the second quarter of 2023 experienced higher legal costs due to senior debt redemption, the proxy filing, and benefit plan reviews.

The year over year increase in noninterest expense is primarily attributable to a $2.1 million increase in salaries and employee benefits, primarily due to an increase in salaries due to higher wage rates and an increase in full-time equivalent employees in the current year. Also contributing to the increase was a $765,000 growth in other expense, which was primarily due to $629,000 of liquidation and deconversion costs recorded on the Visa credit card portfolio liquidation in the third quarter of 2023. Partially offsetting the increase in noninterest expense in the third quarter of 2023, compared to the third quarter of 2022, was a $613,000 decrease in furniture and equipment expenses, a $621,000 decrease in computer and data processing ~~expense was primarily due to core system conversion costs relating to the West Suburban acquisition. Finally, the increase~~expenses, and a $115,000 decrease in ~~other expense was due primarily to growth in bill payment services, consulting~~legal fees, ~~and commercial loan~~all stemming from acquisition related costs ~~primarily due to acquisition-related costs~~that were recorded in the third quarter of 2022.

Noninterest expense for the nine months ended September 30, ~~2022, increased $46.2~~2023, decreased $3.3 million, or ~~70.8%~~3.0%, compared to the nine months ended September 30, ~~2021,~~2022, primarily due to ~~an increase~~a $7.8 million decrease in ~~salaries and employee benefits, occupancy, furniture and equipment,~~ computer and data processing ~~and other expenses, which increases primarily resulted from~~due to acquisition related costs incurred during the nine months ended September 30, 2022 as the result of our acquisition of West Suburban in December 2021. Salaries and employee benefits increased ~~$22.9~~$4.9 million largely from incentives and merit increases effective during the ~~additional employees from West Suburban. Occupancy, furniture and equipment increased $3.7~~nine months ended September 30, 2023. Net teller & bill paying decreased $1.7 million ~~or 51.1%,~~largely due to ~~additional facilities acquired with our~~ acquisition ~~of West Suburban, net of gains from~~related costs that were incurred during the sale of overlapping branches. Computer and data processing increased $8.7 million, or 214.2%, primarily related to costs of operating multiple systems prior to conversion as well as data conversion costs.

Income Taxes

We recorded income tax expense of ~~$7.1~~$8.1 million for the third quarter of ~~2022~~2023 on ~~$26.6~~$32.5 million of pretax income, compared to income tax expense of ~~$4.4~~$9.4 million on ~~$16.7~~$35.0 million of pretax income in the second quarter of ~~2022,~~2023, and income tax expense of ~~$2.9~~$7.1 million on ~~$11.3~~$26.6 million of pretax income in the third quarter of ~~2021.~~2022. Our effective tax rate was ~~26.5%~~25.1% in the third quarter of ~~2022, 26.6%~~2023, 26.9% for the second quarter of ~~2022,~~2023, and ~~25.8%~~26.6% for the third quarter of ~~2021.~~ 2022. The slight reduction in the effective tax rate for the third quarter of 2023 reflects the finalization of the 2022 income tax return, and related adjustments due to state apportionment factor changes and deferred tax allocations within the current period.
We recorded income tax expense of $26.0 million on $99.5 million of pretax income for the nine months ended September 30, 2023, compared to income tax expense of $15.9 million on $59.7 million of pretax income in the like 2022 period. The effective tax rate was 26.1% and 26.7% for the nine months ended September 30, ~~2022, compared to income tax expense of $10.3 million on $39.4 million of pretax income in the like 2021 period. The effective tax rate was 26.7%~~2023 and ~~26.1% for the third quarter of~~ 2022, ~~and the third quarter of 2021,~~ respectively.
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 ~~or nine months~~ ended September 30, ~~2022.~~2023. We had no valuation reserve on the deferred tax assets as of September 30, ~~2022.~~2023.
Financial Condition

Total assets decreased ~~$244.5~~$130.2 million to ~~$5.97~~$5.76 billion at September 30, ~~2022,~~2023, from ~~$6.21~~$5.89 billion at December 31, ~~2021,~~2022, due primarily to ~~a net~~the decrease ~~in cash and cash equivalents~~ of ~~$636.0 million, offset by increases of $444.0~~$309.7 million in ~~net loans and $43.5 million in deferred tax assets.~~securities available-for-sale. The decrease in ~~cash and cash equivalents~~securities available-for-sale was primarily due to ~~the use~~strategic sales. These decreases were partially offset by increases in net loans of ~~cash for loan growth, as well as the decrease in customer deposits~~$157.7 million, FHLB and FRB stock held of ~~$184.9~~$15.3 million, and other assets of $8.7 million. We continue to actively assess potential investment opportunities to utilize our excess liquidity. Total deposits were ~~$5.28~~$4.61 billion at September 30, ~~2022,~~2023, a decrease of ~~$184.9~~$496.4 million from December 31, ~~2021, primarily due to~~2022, through a combination of seasonal ~~decreases of municipal deposits,~~activity as well as leakage from excess savings stemming from COVID-related government payments and ~~to a lesser extent declines in interest bearing demand accounts, savings, money market, NOW, and time deposits in 2022.~~opportunities for alternative investments.

Securities available-for-sale decreased $83.9 million as of September 30, 2022, compared to December 31, 2021, and increased $894.6 million compared to September 30, 2021. The decrease in the portfolio during 2022 was driven by $234.8 million in principal reductions from calls, maturities and mortgage related prepayments, as well as an unrealized mark to market loss adjustment of $146.4 million, which were partially offset by the purchase of $301.6 million across a variety of sectors. 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. The increase in the securities portfolio in the year over year period was primarily due to the securities acquired in the acquisition of West Suburban. There were no securities sales during the third quarter of 2022.

Total loans were ~~$3.87~~$4.03 billion as of September 30, ~~2022,~~2023, an increase of ~~$448.5~~$159.9 million from December 31, ~~2021.~~2022. The increase in total loans in the first nine months of ~~2022,~~2023, compared to December 31, ~~2021,~~2022, was due primarily to growth in loan originations, net of paydowns, within leases of $77.4 million, commercial real estate – investor of $59.5 million and multifamily of $48.3 million offset by net reductions in commercial real estate – owner occupied of $45.8 million from December 31, 2022. Total loans increased $160.2 million from September 30, 2022 to September 30, 2023, primarily due to growth in loan originations, net of paydowns, within commercial real estate – investor ~~which increased~~of $105.2 million, leases of $103.2 million and multifamily of $49.2 million, offset by ~~$142.0 million,~~net reductions in commercial real estate – owner occupied ~~which increased by $145.1 million, commercial, which increased by $116.6~~of $67.9 million and leases, which increased by $75.6 million from December 31, 2021. Total loans increased $2.00 billion from September 30, 2021 to September 30, 2022, primarily due to the loan portfolio acquired from West Suburban.commercial of $53.2 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 ~~70.2%~~69.8% of the portfolio as of September 30, ~~2022,~~2023, compared to ~~71.6%~~70.6% of the portfolio as of

~~Tableof Contents~~

December 31, ~~2021.~~ 2022. At September 30, 2023, our outstanding commercial real estate loans and undrawn commercial real estate commitments, excluding owner occupied real estate were equal to 288.9% of our Tier 1 capital plus allowance for credit losses, an increase from 304.2% at December 31, 2022. 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 ~~performing restructured accruing loans~~ and loans 90 days or greater past due. ~~Remediation work continues in all segments.~~Prior to January 1, 2023, nonperforming loans also included performing troubled debt restructured loans accruing interest. Nonperforming loans increased by ~~$8.2~~$30.4 million to $63.3 million at September 30, 2023 from $32.9 million at December 31, 2022 and increased $10.4 million from $52.9 million at September 30, ~~2022 from $44.7 million at December 31, 2021.~~2022. 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 September 30, 2023, 0.9% as of December 31, 2022, and 1.4% as of September 30, ~~2022, 1.3% as of December 31, 2021, and 1.5% as of September 30, 2021.~~2022.

Net charge-offs of ~~$68,000~~$6.6 million were recorded for the third quarter of ~~2022,~~2023, compared to net charge-offs of ~~$250,000~~$505,000 for the second quarter of ~~2022,~~2023, and net charge-offs of ~~$237,000~~$68,000 for the third quarter of ~~2021,~~2022, reflecting continuing management attention to credit quality and remediation efforts. The net charge-offs for the third quarter of ~~2022~~2023 were primarily due to ~~one lease~~ charge ~~off for $178,000 and one~~offs of three commercial real ~~estate – investor charge off for $94,000.~~estate-investor loans of $6.8 million in aggregate. These three commercial real estate-investor credits had a reported reserve allocation of $4.7 million prior to the third quarter of 2023 charge-offs. We have continued our conservative loan valuations and aggressive recovery efforts on prior charge-offs.

Classified loans include nonaccrual ~~performing troubled debt restructurings~~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.

Total classified loans increased $44.3 million and classified assets increased ~~$38.2~~$43.2 million as of September 30, ~~2022,~~2023 from ~~the levels at~~ December 31, ~~2021.~~2022. The increase since December 31, 2022 is due to the addition of $26.7 million of classified loans in commercial real estate – investor, ~~loans totaling $19.7 million~~primarily due to four large credits, two of which are office buildings, one is an assisted living facility during the first six months of 2023, and ~~two commercial real estate – owner occupied loans totaling $32.0 million~~one office building in the ~~second quarter.~~third quarter of 2023. The increase is also due to the growth in construction, primarily due to two large credits. The increase from September 30, ~~2021~~2022 is primarily due to the ~~$15.4 million addition of the West Suburban~~same loan ~~portfolio in late 2021.~~additions to commercial real estate – investor and construction. 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 ~~19.23%~~23.51% for the period ended September 30, ~~2022,~~2023, compared to ~~13.79%~~18.36% as of December 31, ~~2021,~~2022, and ~~9.73%~~19.23% as of September 30, ~~2021. The increase in the classified assets ratio for the period ended September 30, 2022, compared to September 30, 2021, is also due to the acquisition of West Suburban.~~2022.

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 ~~ACL~~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. ~~As of January 1, 2020, we adopted ASU 2016-13, or CECL.~~

At September 30, ~~2022,~~2023, our ~~allowance for credit losses, or~~ ACL on loans totaled ~~$48.8~~$51.7 million, and our ACL on unfunded commitments, included in other liabilities, totaled ~~$4.4~~$2.9 million. In the third quarter of ~~2022,~~2023, we recorded provision expense on loans of ~~$3.5~~$3.0 million, based on our assessment of nonperforming loan metrics and trends and estimated future credit losses, and a ~~$973,000 increase in our reserve~~$12,000 reversal of provision on unfunded commitments, primarily due to an ~~updated analysis~~adjustment of ~~line utilization~~historical benchmark assumptions, such as funding rates ~~over~~and the ~~past twelve months, as well as the roll off of prior historical periods with lower losses~~period used to forecast those rates, within the ~~CECL model.~~ACL calculation. These ~~two entries~~adjustments resulted in a ~~$4.5~~$3.0 million net impact to the provision for credit losses for the third quarter of ~~2022.~~

The ACL on loans totaled $45.4 million as of June 30, 2022, $44.3 as of December 31, 2021, and $26.9 million as of September 30, 2021. The ACL on loans increased in late 2021 due to the impact of the West Suburban acquisition Day One credit mark of $12.1 million, the Day Two non-PCD loan adjustment to ACL of $12.2 million, less a reversal of $2.3 million related to our legacy loan portfolio and net charge-offs of $4.7 million for the fourth quarter. The ACL for loans was reduced in the third quarter of 2021 due to a $1.5 million release of the provision for credit losses.2023.

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 $51.7 million as of September 30, 2023, $49.5 million as of December 31, 2022, and $48.8 million as of September 30, 2022. Our ACL on loans to total loans was 1.3% as of September 30, 2023, compared to 1.3% as of December 31, 2022 and ~~December 31, 2021.~~September 30, 2022. See Item 7 – Critical Accounting Estimates in the Management Discussion and Analysis in our ~~2021~~2022 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.

The coverage ratio of the ACL on loans to nonperforming loans was ~~92.3%~~81.3% as of September 30, ~~2022,~~2023, which was a decrease from the coverage ratio of ~~107.8%~~90.3% as of June 30, ~~2022~~2023 and a decrease from ~~93.1%~~92.3% as of September 30, ~~2021.~~2023. When measured as a percentage of average loans, our total ACL on loans was ~~1.37% for the nine months ended 2022 and 1.39% for the like period of~~1.29% at September 30, ~~2021~~2023, 1.37% at June 30, 2023, and 1.30% at September 30, 2022.

In management’s judgment, an adequate ACL has been established to encompass the current lifetime expected credit losses at September 30, ~~2022,~~2023, and general changes in lending policy, procedures and staffing, as well as other external ~~factors, such as the impacts of the COVID-19 pandemic.~~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.

~~Other Real Estate Owned~~

As of September 30, 2022, OREO totaled $1.6 million, reflecting a $795,000 decrease from the $2.4 million at December 31, 2021, and a $351,000 decrease from the $1.9 million at September 30, 2021. In the third quarter of 2022, we disposed of one property totaling $62,000 in net book value, which resulted in a gain on sale of OREO of $33,000 and had no transfers to OREO. In the fourth quarter of 2021, we acquired three OREO properties in our acquisition of West Suburban, with a total fair value of $5.6 million, and we sold two of these properties in December, which had a net book value of $5.2 million. In the third quarter of 2022, we recorded no OREO valuation reserve adjustments, compared to $14,000 of valuation reserve adjustments recorded in the fourth quarter of 2021, and $2,000 of valuation reserve adjustments recorded in the third quarter of 2021.

In management’s judgment, the property valuation allowance as established presents OREO at current estimates of fair value less estimated costs to sell; however, there can be no assurance that additional losses will not be incurred on disposals or upon updates to valuations in the future. Of note, properties valued in total at $928,000, or approximately 59.5% of total OREO at September 30, 2022, have been in OREO for five years or more. The appropriate regulatory approval has been obtained for any OREO properties held in excess of five years.

Total deposits were ~~$5.28~~$4.61 billion at September 30, ~~2022,~~2023, which reflects a ~~$184.9~~$496.4 million decrease from total deposits of ~~$5.47~~$5.11 billion at December 31, ~~2021,~~2022, and ~~an increase~~a decrease of ~~$2.57 billion~~$667.0 million from total deposits of ~~$2.71~~$5.28 billion at September 30, ~~2021.~~2022. The decrease in deposits at September 30, ~~2022,~~2023, compared to December 31, ~~2021,~~2022, was primarily due to decreases in ~~savings~~noninterest-bearing deposits of ~~$14.5~~$189.0 million, money market accounts of $160.0 million and savings accounts of $142.1 million. The decrease in deposits at September 30, 2023, compared to September 30, 2022, was primarily due to decreases in noninterest-bearing deposits of $235.5 million, money market accounts of $229.6 million, and savings accounts of $160.5 million. Total quarterly average deposits decreased $659.4 million, or 12.4%, in the year over year period, driven by declines in our average demand deposits of $225.1 million, and savings, NOW and money markets combined of $440.7 million. 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, materially offsetting the significant expansion in those same accounts in the immediate aftermath of the pandemic.

The following table presents estimated insured and uninsured deposits at September 30, 2023 and December 31, 2022 by deposit type, as well as the weighted average rates for each year to date ending period.

Deposits declined 9.7% for the nine months ended September 30, 2023 due to retail and commercial run off. Total deposit run off year to date has been very granular, and not necessarily attributable to large deposit accounts. Our deposit retention efforts for commercial clients were more effective due to high touch relationships where we had a larger share of wallet. The largest reduction in total deposits was from retail customers due to personal and real estate tax payments, real estate transactions, investments, and consumer spending. In terms of product mix, we observed some migration into time deposits, drawn by CD rate specials. Overall, our deposit level remains stable and we continue to monitor customer relationships and liquidity levels daily.

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 $25.9 million at September 30, 2023, a $6.3 million, or 19.5%, decrease from $32.2 million at December 31, 2022. Our excess liquidity on hand during much of 2022 allowed us to fund our short-term liquidity needs with cash on hand. During the third quarter of 2022, we began re-utilizing short-term borrowings from the FHLBC. The outstanding balance of our short-term FHLBC borrowings was $435.0 million as of September 30, 2023, $90.0 million as of December 31, 2022, and $25.0 million as of September 30, 2022.

The increase in deposits at September 30, 2022, compared to September 30, 2021 was primarily due to an increase of $2.69 billion of deposits from the West Suburban acquisition.

In addition to deposits, we obtained funding from other sources in all periods presented. Securities sold under repurchase agreements totaled $35.5 million at September 30, 2022, a $14.8 million, or 29.5%, decrease from $50.3 million at December 31, 2021.

In the second quarter of 2021, we entered into Subordinated Note Purchase Agreements with certain qualified institutional buyers pursuant to which we ~~sold and~~ 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 ~~are intended to be~~were used for general corporate ~~purposes, which may include, without limitation, the redemption of existing senior debt, common stock repurchases and strategic acquisitions.~~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~~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.

Partially offsetting this decrease was $43.8 million of net income for the nine months ended September 30, 2022.~~2023, due to changes in market interest rates.

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 September 30, ~~2022, the~~2023, our capital measures ~~of the Company~~ exclude ~~$2.9~~$1.9 million, which is the modified CECL transition adjustment.

As of September 30, ~~2022,~~2023, the Company, on a consolidated basis, exceeded the minimum capital ratios to be deemed “well capitalized” and met the ~~now fully phased-in~~ 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, ~~decreased~~increased from ~~8.08%~~7.83% at December 31, ~~2021,~~2022, to ~~7.27%~~9.25% at September 30, ~~2022.~~2023. Our GAAP tangible common equity to tangible assets ratio was ~~5.67%~~7.67% at September 30, ~~2022,~~2023, compared to ~~6.54%~~6.24% as of December 31, ~~2021.~~2022. Our non-GAAP tangible common equity to tangible assets ratio, which management also considers a valuable performance measurement for capital analysis, ~~decreased~~increased from ~~6.59%~~6.28% at December 31, ~~2021,~~2022, to ~~5.72%~~7.71% at September 30, ~~2022,~~2023, primarily due to ~~a decline~~an increase in tangible common equity in the ~~nine months ended September 30, 2022.~~third quarter of 2023. The ~~decline~~increase in tangible common equity was due to ~~a decrease~~an increase in retained earnings of $66.8 million and an increase in accumulated other comprehensive ~~income~~loss of ~~$107.2~~$2.5 million primarily related to improved unrealized losses on available-for-sale securities stemming from the ~~increase~~changes in market interest rates. ~~The non-GAAP tangible common equity to tangible assets ratio was also negatively impacted by growth in total tangible assets in the third quarter of 2022.~~

The non-GAAP intangible asset exclusion reflects the 80% core deposit limitation per Basel III guidelines within risk based capital calculations, and is useful for us when reviewing risk based capital ratios and equity performance metrics.

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 third quarter of 2023, we continued to experience moderate loan growth, while deposits have trended down as clients moved balances to pursue higher yields as well as due to seasonal declines. 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 in the first five months of 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, ~~due to the potential impacts on our liquidity stemming from the COVID-19 pandemic,~~ our senior management team monitors cash balances daily to ensure we have adequate liquidity to meet our operational and financing needs. As of September 30, ~~2022,~~2023, our cash on hand liquidity totaled ~~$116.2~~$109.0 million, a decrease of ~~$636.0~~$6.1 million over cash balances held as of December 31, ~~2021.~~2022.

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.

In the first nine months of 2023, securities transactions accounted for net inflows of $306.0 million, and the principal change on loans accounted for net outflows of $164.3 million. In the first nine months of 2022, securities transactions accounted for net outflows of $66.9 million, and ~~the~~ principal ~~change~~ on loans funded, net of paydowns, accounted for net outflows of $443.6 million. In the first nine months of 2021, securities transactions accounted for net outflows of $225.2 million, and net principal on loans funded accounted for net inflows of $168.6 million. Proceeds from sales of OREO accounted for $941,000 and $607,000 in investing cash inflows for the nine months ended September 30, 2022 and 2021, respectively.

Net cash outflows from financing activities in the nine months ended September 30, ~~2022,~~2023, were ~~$189.7~~$218.0 million, compared with net cash ~~inflows~~outflows of ~~$195.6~~$189.7 million in the nine months ended September 30, ~~2021.~~2022. Net deposit outflows in the first nine months of ~~2022~~2023 were ~~$183.7~~$495.4 million compared to net deposit ~~inflows~~outflows of ~~$177.3~~$183.7 million in the first nine months of ~~2021.~~2022. Other short-term borrowings had ~~$25.0~~$345.0 million of net cash inflows in the first nine months of ~~2022,~~2023, compared to nonet cash inflows ~~or outflows~~of $25.0 million for other short-term borrowings in the first nine months of ~~2021.~~2022.

Dividends paid on our common stock totaled $6.7 million infor both the nine months ended September 30, ~~2022, compared to dividends paid of $3.2 million for the like 2021 period, as the per common share dividend was increased to five cents per share in the second quarter of 2021.~~2023 and 2022.

Cash and cash equivalents for the nine months ended September 30, ~~2022,~~2023, totaled ~~$116.2~~$109.0 million, as compared to ~~$519.3~~$115.2 million as of December 31, 2022 and $116.2 million as of September 30, ~~2021.~~2022. The decrease in cash and cash equivalents for the nine months ended September 30, 2023 was mainly attributable to loan growth and the payoffs of the remaining balance of the term note and senior notes, as well as deposit outflows, partially offset by security sales and FHLB advances during the first nine months of 2023. The year over year decrease is again driven by loan growth, as well as increased customer use of deposits. 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.

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~~During the third quarter of 2023, the Federal Reserve ~~has continued its pace of rate hikes~~increased rates by 0.25% in July and ~~raised~~held rates unchanged at the ~~federal funds target rate by another 0.75% in~~ September ~~2022.~~FOMC meeting. The current market expectation is ~~a federal funds target~~for rates to be unchanged for the remainder of 2023. The projected level of rate ~~of 4.50% by the end of~~cuts in 2024 have been reduced and moved to later in the year, ~~however the outlook on~~framing a “higher rates ~~have been constantly changing as new economic measures are published.~~for a longer period” outcome. The Federal Reserve ~~has been slow in shrinking~~managed to shrink its balance sheet ~~which decreased~~to $8.0 trillion by September 2023, down from ~~$9.0~~its peak of $8.7 trillion in March ~~2022 to $8.8 trillion in September 2022.~~ 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 September 30, ~~2022~~2023 and December 31, ~~2021~~2022 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 ~~LIBOR~~SOFR and ~~prime)~~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, ~~2021.~~2022. 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. Recent market events of failed liquidity management at other banks have been reviewed by the Asset-Liability committee. The committee concluded that we possess a strong liquidity profile 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 September 30, ~~2022,~~2023, our net interest income profile remained sensitive to earnings gains (in both dollars and percentage) should interest rates rise. However, we have moved to a ~~lower sensitivity~~less sensitive profile ~~relative~~compared to December 31, ~~2021 from~~2022, due to the impact of interest rate swaps and ~~mix changes in loans.~~sales of variable rate securities.

Tableof 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. Due to relatively low market interest rates, it was not possible to calculate any down rate scenarios for December 31, 2021 results because many of the market interest rates would fall below zero in that scenario.

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; however,~~rate, we monitor both. The annual US inflation rate for September 2023 was ~~8.2% in September 2022,~~3.7%, a ~~slight reduction from its peak of 9.1% in June 2022.~~moderate increase quarter-over-quarter, while Core CPI eased to 4.1%.

In general, we anticipate that higher inflation will increase borrowers’ needs for credit~~come down, albeit at a much slower rate than experienced year-to-date as ~~a result~~ of ~~GDP growth. In addition, as interest rates are expected to rise to combat inflation, we also expect our net interest margin to be favorably impacted.~~September 2023.

Furthermore, higher costs of living weaken the financial condition of our borrowers which could affect our credit profile. A financial institution’s ability to be relatively unaffected by changes in interest rates is a good indicator of its capability to perform in today’s volatile economic environment. We seek to mitigate the impact of interest rate volatility on the Bank by seeking to ensure that rate sensitive assets and rate sensitive liabilities respond to changes in interest rates in a similar time frame and to a similar degree. Overall, we expect the ~~effects~~risk of ~~higher~~high inflation has been contained with minimal impact to ~~be beneficial to us in the near term.~~

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 September 30, ~~2022.~~2023. Based on that evaluation, the Chief Executive Officer and Chief Financial Officer concluded that as of September 30, ~~2022,~~2023, 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 September 30, ~~2022,~~2023, 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.
