Nature of Operations and Summary of Significant Accounting Policies	Note 1 — Nature of Operations and Summary of Significant Accounting Policies Nature of Operations The accounting and reporting practices of First Business Financial Services, Inc. (“FBFS” or the “Corporation”), through our wholly-owned subsidiary, First Business Bank (“FBB” or the “Bank”), have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”). FBB operates as a commercial banking institution primarily in Wisconsin and the greater Kansas City metropolitan area. The Bank provides a full range of financial services to businesses, business owners, executives, professionals, and high net worth individuals. FBB also offers bank consulting services to community financial institutions. The Bank is subject to competition from other financial institutions and service providers and is also subject to state and federal regulations. As of June 30, 2024, FBB had the following wholly-owned subsidiaries: First Business Specialty Finance, LLC (“FBSF”), First Madison Investment Corp. (“FMIC”), ABKC Real Estate, LLC (“ABKC”), FBB Real Estate 2, LLC (“FBB RE 2”), Mitchell Street Apartments Investment, LLC (“Mitchell Street”), and FBB Tax Credit Investment, LLC (“FBB Tax Credit”). Basis of Presentation The accompanying unaudited Consolidated Financial Statements were prepared in accordance with GAAP and the instructions to Form 10-Q and Rule 10-01 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by GAAP for complete financial statements and should be read in conjunction with the Corporation’s Consolidated Financial Statements and footnotes thereto included in the Corporation’s Annual Report on Form 10-K for the year ended December 31, 2023. The unaudited Consolidated Financial Statements include the accounts of the Corporation and its wholly-owned subsidiaries. All significant intercompany balances and transactions have been eliminated in consolidation. Management of the Corporation is required to make estimates and assumptions which affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements as well as reported amounts of revenues and expenses during the reporting period. Actual results could differ significantly from those estimates. Material estimates that could significantly change in the near-term include the value of securities and interest rate swaps, level of the allowance for credit losses, lease residuals, property under operating leases, goodwill, and income taxes . The results of operations for the three and six months ended June 30, 2024, are not necessarily indicative of results that may be expected for any other interim period or the entire fiscal year ending December 31, 2024 . Certain amounts in prior periods may have been reclassified to conform to the current presentation. Subsequent events have been evaluated through the date of the issuance of the unaudited Consolidated Financial Statements. No significant subsequent events have occurred through this date requiring adjustment to the financial statements or disclosures. The Corporation has not changed its significant accounting and reporting policies from those disclosed in the Corporation’s Form 10-K for the year ended December 31, 2023. Recent Accounting Pronouncements In November 2023, the FASB issued ASU No. 2023-07, “Segment Reporting (Topic 820): Improvements to Reportable Segment Disclosures.” This update is intended to improve reportable segment disclosure requirements, primarily through enhanced disclosures about significant segment expenses. This update is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2024. The Corporation is one operating segment; therefore, we do not anticipate any impact to the financial statements. In December 2023, the FASB issued ASU No. 2023-09, “Income Taxes (Topic 740): Improvements to Income Tax Disclosures.” This update enhances the transparency and decision usefulness of income tax disclosures by providing better information regarding exposure to potential changes in jurisdictional tax legislation and related forecasting and cash flow opportunities. This update is effective for fiscal years beginning after December 15, 2024. The Corporation is assessing the impact of the standard.

Earnings Per Share [Abstract]
Earnings Per Common Share	Note 2 — Earnings per Common Share Earnings per common share are computed using the two-class method. Basic earnings per common share are computed by dividing net income allocated to common shares by the weighted-average number of shares outstanding during the applicable period, excluding outstanding participating securities. Participating securities include unvested restricted shares. Unvested restricted shares are considered participating securities because holders of these securities receive non-forfeitable dividends, or dividend equivalents, at the same rate as holders of the Corporation’s common stock. Diluted earnings per share are computed by dividing net income allocated to common shares adjusted for reallocation of undistributed earnings of unvested restricted shares by the weighted average number of shares determined for the basic earnings per common share computation plus the dilutive effect of common stock equivalents using the treasury stock method.

Share-Based Compensation

Share-Based Compensation	6 Months Ended

Share-Based Payment Arrangement [Abstract]
Share-Based Compensation	Note 3 — Share-Based Compensation The Corporation initially adopted the 2019 Equity Incentive Plan (the “Plan”) during the quarter ended June 30, 2019. The Plan is administered by the Compensation Committee of the Board of Directors (the “Board”) of the Corporation and provides for the grant of equity ownership opportunities through incentive stock options and nonqualified stock options, restricted stock, restricted stock units, dividend equivalent units, and any other type of award permitted by the Plan. As of June 30, 2024, 267,882 shares were available for future grants under the Plan, as amended. Shares covered by awards that expire, terminate, or lapse will again be available for the grant of awards under the Plan. Restricted Stock Under the Plan, the Corporation may grant restricted stock awards (“RSA”), restricted stock units (“RSU”), and other stock-based awards to plan participants, subject to forfeiture upon the occurrence of certain events until the dates specified in the participant’s award agreement. While restricted stock is subject to forfeiture, RSA participants may exercise full voting rights and will receive all dividends and other distributions paid with respect to the restricted shares. RSUs do not have voting rights. RSUs granted prior to 2023 are provided dividend equivalents concurrent with dividends paid to shareholders while RSUs granted in 2023 and after will accrue dividend equivalents payable upon vesting. The restricted stock granted under the Plan is typically subject to a vesting period. Compensation expense for restricted stock is recognized over the requisite service period of generally three or four years for the entire award on a straight-line basis. Upon vesting of restricted stock, the benefit of tax deductions in excess of recognized compensation expense is reflected as an income tax benefit in the unaudited Consolidated Statements of Income. The Corporation may also issue performance-based restricted stock units (“PRSU”). Vesting of the PRSU will be measured on the relative Total Shareholder Return (“TSR”) and relative Return on Average Equity (“ROAE”) for issuances prior to 2023 or Return on Average Common Equity (“ROACE”) for issuances after 2022, and will cliff-vest after a three-year measurement period based on the Corporation’s TSR performance and ROAE or ROACE performance compared to a broad peer group of over 100 banks. At the end of the performance period, the number of actual shares to be awarded varies between 0 % and 200 % of target amounts. The restricted stock awards and units issued to executive officers will vest ratably over a three-year period. Compensation expense is recognized for PRSU over the requisite service and performance period of generally three years for the entire expected award on a straight-line basis. The compensation expense for the awards expected to vest for the percentage of performance-based restricted stock units subject to the ROAE or ROACE metric will be adjusted if there is a change in the expectation of ROAE or ROACE. The compensation expense for the awards expected to vest for the percentage of PRSU subject to the TSR metric are never adjusted and are amortized utilizing the accounting fair value provided using a Monte Carlo pricing model. Restricted stock activity for the year ended December 31, 2023 and the six months ended June 30, 2024 was as follows: RSA Weighted Average PRSU Weighted Average RSU Weighted Average Total Weighted Average Nonvested balance as of December 31, 2022 133,317 $ 27.95 57,435 $ 32.89 6,105 $ 25.92 196,857 $ 29.32 Granted (1) — — 34,840 35.79 54,955 34.43 89,795 34.96 Vested ( 56,931 ) 27.03 ( 36,120 ) 31.31 ( 3,253 ) 26.06 ( 96,304 ) 28.60 Forfeited ( 4,435 ) 30.20 — — ( 820 ) 36.42 ( 5,255 ) 31.17 Nonvested balance as of December 31, 2023 71,951 28.53 56,155 35.70 56,987 33.97 185,093 32.38 Granted (1) — — 27,614 34.76 63,577 29.90 91,191 31.37 Vested ( 33,369 ) 26.87 ( 34,139 ) 25.43 ( 31,859 ) 20.76 ( 99,367 ) 24.42 Forfeited ( 5,285 ) 30.26 — — ( 4,275 ) 36.29 ( 9,560 ) 32.96 Nonvested balance as of June 30, 2024 33,297 $ 29.92 49,630 $ 42.24 84,430 $ 35.77 167,357 $ 36.52 Unrecognized compensation cost (in thousands) $ 744 $ 1,343 $ 2,670 $ 4,757 Weighted average remaining recognition period (in years) 1.39 1.96 2.89 2.39 (1) The number of restricted shares/units shown includes the shares that would be granted if the target level of performance is achieved related to the PRSU. The number of shares actually issued may vary. During the six months ended June 30, 2024, an additional 10,589 were issued related to actual performance results of previously granted awards. Employee Stock Purchase Plan The Corporation is authorized to issue up to 250,000 shares of common stock under the employee stock purchase plan ("ESPP"). The plan qualifies as an employee stock purchase plan under section 423 of the Internal Revenue Code of 1986. Under the ESPP, eligible employees may enroll in a three month offer period that begins January, April, July, and October of each year. Employees may elect to purchase a limited number of shares of the Corporation's common stock at 90 % of the fair market value on the last day of the offering period. The ESPP is treated as a compensatory item for purposes of share-based compensation expense. During the six months ended June 30, 2024 , the Corporation issued 1,862 shares of common stock under the ESPP. As of June 30, 2024, 228,776 shares remained available for issuance under the ESPP. Share-based compensation expense related to restricted stock and ESPP included in the unaudited Consolidated Statements of Income was as follows: For the Three Months Ended June 30, For the Six Months Ended June 30, 2024 2023 2024 2023 (In Thousands) Share-based compensation expense $ 624 $ 1,072 $ 1,289 $ 1,706

The Corporation has not specifically identified available-for-sale securities in a loss position that it intends to sell in the near term and does not believe that it will be required to sell any such securities. The Corporation reviews its securities on a quarterly basis to assess declines in fair value for credit losses. Consideration is given to such factors as the credit rating of the borrower, market conditions such as current interest rates, any adverse conditions specific to the security, and delinquency status on contractual payments. For the three and six months ended June 30, 2024 and 2023, management concluded that in all instances securities with fair value less than carrying value was due to market factors; thus, no credit loss provision was required.

At June 30, 2024, the Corporation held 23 held-to-maturity securities that were in an unrealized loss position, 22 of which have been in a continuous loss position for twelve months or greater. Management assesses held-to-maturity securities for credit losses on a quarterly basis. The assessment includes review of credit ratings, identification of delinquency and evaluation of market factors. Based on this analysis, management concludes the decline in fair value is due to market factors, specifically changes in interest rates.

The Corporation primarily uses a nine grade risk rating system to monitor the ongoing credit quality of its loans and leases. The risk rating grades follow a consistent definition and are then applied to specific loan types based on the nature of the loan. Each risk rating is determined based on various quantitative and qualitative factors and is subject to various levels of review and concurrence on the stated risk rating. In addition to its nine grade risk rating system, the Corporation groups loans into four loan and related risk categories which determine the level and nature of review by management. Category I — Loans and leases in this category are performing in accordance with the terms of the contract and generally exhibit no immediate concerns regarding the security and viability of the underlying collateral, financial stability of the borrower, integrity or strength of the borrowers’ management team, or the industry in which the borrower operates. The Corporation monitors Category I loans and leases through payment performance, continued maintenance of its personal relationships with such borrowers, and continued review of such borrowers’ compliance with the terms of their respective agreements. Category II — Loans and leases in this category are beginning to show signs of deterioration in one or more of the Corporation’s core underwriting criteria such as financial stability, management strength, industry trends, or collateral values. Management will place credits in this category to allow for proactive monitoring and resolution with the borrower to possibly mitigate the area of concern and prevent further deterioration or risk of loss to the Corporation. Category II loans are considered performing but are monitored frequently by the assigned business development officer and by asset quality review committees. Category III — Loans and leases in this category are identified by management as warranting special attention. However, the balance in this category is not intended to represent the amount of adversely classified assets held by the Bank. Category III loans and leases generally exhibit undesirable characteristics, such as evidence of adverse financial trends and conditions, managerial problems, deteriorating economic conditions within the related industry, or evidence of adverse public filings and may exhibit collateral shortfall positions. Management continues to believe that it will collect all contractual principal and interest in accordance with the original terms of the contracts relating to the loans and leases in this category, and therefore Category III loans are considered performing with no specific reserves established for this category. Category III loans are monitored by management and asset quality review committees on a monthly basis. Category IV — Loans and leases in this category are non-accrual loans. Management has determined that it is unlikely that the Bank will receive the contractual principal and interest in accordance with the original terms of the agreement. Non-accrual loans are individually evaluated to assess the need for the establishment of specific reserves or charge-offs. When analyzing the adequacy of collateral, the Corporation obtains external appraisals at least annually. External appraisals are obtained from the Corporation’s approved appraiser listing and are independently reviewed to monitor the quality of such appraisals. To the extent a collateral shortfall position is present, a specific reserve or charge-off will be recorded. Loans and leases in this category are monitored by management and asset quality review committees on a monthly basis.

There were seven commercial and industrial loans for a total of $ 1.6 million and two commercial real estate non-owner occupied loans for a total of $ 5.9 million modified during the six months ended June 30, 2024 . The modifications consisted of payment deferrals and modified loan repayment schedules. Of these modified loans, four are included in total non-performing loans and are currently between zero and 117 days past due as of June 30, 2024. There was one commercial and industrial loan for a total of $ 382,000 modified during the six months ended June 30, 2023. This modification consisted of a payment deferral. There was one commercial and industrial loan to borrowers experiencing financial distress in the amount of $ 238,000 that was modified during the 12 months ended June 30, 2024 which subsequently defaulted . There were no loans to borrowers experiencing financial distress that were modified during the 12 months ended June 30, 2023 which subsequently defaulted . There were no unfunded commitments associated with loans modified for borrowers experiencing financial distress as of June 30, 2024. Allowance for Credit Losses The ACL is an estimate of the expected credit losses on financial assets measured at amortized cost, which is measured using relevant information about past events, including historical credit loss experience on financial assets with similar risk characteristics, current conditions, and reasonable and supportable forecasts that affect the collectability of the remaining cash flows over the contractual term of the financial assets. A provision for credit losses is charged to operations based on management’s periodic evaluation of these and other pertinent factors as discussed within Note 1 – Nature of Operations and Summary of Significant Accounting Policies included in the Corporation’s Form 10-K for the year ended December 31, 2023. Quantitative Considerations The ACL is primarily calculated utilizing a discounted cash flow (“DCF”) model. Key inputs and assumptions used in this model are discussed below: • Forecast model - For each portfolio segment, a loss driver analysis (“LDA”) was performed in order to identify appropriate loss drivers and create a regression model for use in forecasting cash flows. The LDA analysis utilized peer FFIEC Call Report data for all pools. The Corporation plans to update the LDA annually. • Probability of default ("PD") – PD is the probability that an asset will be in default within a given time frame. The Corporation has defined default as when a charge-off has occurred, a loan goes to non-accrual status, or a loan is greater than 90 days past due. The forecast model is utilized to estimate PDs. • Loss given default ("LGD") – LGD is the percentage of the asset not expected to be collected due to default. The LGD is derived from using a method referred to as Frye Jacobs which uses industry data. • Prepayments and curtailments – Prepayments and curtailments are calculated based on the Corporation’s own data. This analysis is updated semi-annually. • Forecast and reversion – The Corporation has established a one-year reasonable and supportable forecast period with a one-year straight line reversion to the long-term historical average. • Economic forecast – The Corporation utilizes a third party to provide economic forecasts under various scenarios, which are assessed against economic indicators and management’s observations in the market. As of December 31, 2023, the Corporation selected a forecast which estimates unemployment between 3.89% and 4.04% and GDP growth change between 1.29% and 2.32% over the next four quarters. As of June 30, 2024, the Corporation selected a forecast which estimates unemployment between 4.06% and 4.08% and GDP growth change between 1.76% and 2.21% over the next four quarters. Following the forecast period, the model reverts to long-term averages over four quarters. Management believes that the resulting quantitative reserve appropriately balances economic indicators with identified risks. Qualitative Considerations In addition to the quantitative model, management considers the need for qualitative adjustment for risks not considered in the DCF. Factors that are considered by management in determining loan collectability and the appropriate level of the ACL are listed below: • The Corporation’s lending policies and procedures, including changes in lending strategies, underwriting standards and practices for collections, write-offs, and recoveries; • Actual and expected changes in international, national, regional, and local economic and business conditions and developments in which the Corporation operates that affect the collectability of financial assets; • The experience, ability, and depth of the Corporation’s lending, investment, collection, and other relevant management and staff; • The volume of past due financial assets, the volume of non-accrual loans and leases, and the volume and severity of adversely classified or graded assets; • The existence and effect of industry concentrations of credit; • The nature and volume of the portfolio segment or class; • The quality of the Corporation’s credit function; and • The effect of other external factors such as the regulatory, legal and technological environments, competition, and events such as natural disasters or pandemics.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Note 11 — Commitments and Contingencies In the normal course of business, various legal proceedings involving the Corporation are pending. Management, based upon advice from legal counsel, does not anticipate any significant losses as a result of these actions. Management believes that any liability arising from any such proceedings currently existing or threatened will not have a material adverse effect on the Corporation’s financial position, results of operations, and cash flows. The Corporation sells the guaranteed portions of SBA 7(a) and 504 loans, as well as participation interests in other, non-SBA originated, loans to third parties. The Corporation has a continuing involvement in each of the transferred lending arrangements by way of relationship management and servicing the loans, as well as being subject to normal and customary requirements of the SBA loan program and standard representations and warranties related to sold amounts. In the event of a loss resulting from default and a determination by the SBA that there is a deficiency in the manner in which the loan was originated, funded, or serviced by the Corporation, the SBA may require the Corporation to repurchase the loan, deny its liability under the guaranty, reduce the amount of the guaranty, or, if it has already paid under the guaranty, seek recovery of the principal loss related to the deficiency from the Corporation. The Corporation must comply with applicable SBA regulations in order to maintain the guaranty. In addition, the Corporation retains the option to repurchase the sold guaranteed portion of an SBA loan if the loan defaults. Management has assessed estimated losses inherent in the outstanding guaranteed portions of SBA loans sold in accordance with ASC 450, Contingencies , and determined a recourse reserve based on the probability of future losses for these loans to be $ 906,000 at June 30, 2024, which is reported in accrued interest payable and other liabilities on the unaudited Consolidated Balance Sheets.

Fair Value Disclosures

Fair Value Disclosures	6 Months Ended

Fair Value Disclosures [Abstract]
Fair Value Disclosures	Note 12 — Fair Value Disclosures The Corporation determines the fair values of its financial instruments based on the fair value hierarchy established in ASC Topic 820, which requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. Fair value is defined as the price that would be received in an orderly transaction that is not a forced liquidation or distressed sale at the measurement date and is based on exit prices. Fair value includes assumptions about risk, such as nonperformance risk in liability fair values, and is a market-based measurement, not an entity-specific measurement. The standard describes three levels of inputs that may be used to measure fair value. Level 1 — Level 1 inputs are unadjusted quoted prices in active markets for identical assets or liabilities that the Corporation has the ability to access at the measurement date. Level 2 — Level 2 inputs are inputs, other than quoted prices included with Level 1, that are observable for the asset or liability either directly or indirectly, such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities. Level 3 — Level 3 inputs are supported by little or no market activity and are significant to the fair value of the assets or liabilities. In instances where the determination of the fair value measurement is based on inputs from different levels of the fair value hierarchy, the level in the fair value hierarchy within which the entire fair value measurement falls is based on the lowest level input that is significant to the fair value measurement in its entirety. The Corporation’s assessment of the significance of a particular input to the fair value measurement in its entirety requires judgment and considers factors specific to the asset or liability. Assets and liabilities measured at fair value on a recurring basis, segregated by fair value hierarchy level, are summarized below: June 30, 2024 Fair Value Measurements Using Level 1 Level 2 Level 3 Total (In Thousands) Assets: Securities available-for-sale: U.S. treasuries $ — $ 9,583 $ — $ 9,583 U.S. government agency securities - government-sponsored — 8,068 — 8,068 Municipal securities — 34,862 — 34,862 Residential mortgage-backed securities - government issued — 101,743 — 101,743 Residential mortgage-backed securities - government- — 124,296 — 124,296 Commercial mortgage-backed securities - government issued — 2,301 — 2,301 Commercial mortgage-backed securities - government- — 27,999 — 27,999 Interest rate swaps — 70,773 — 70,773 Liabilities: Interest rate swaps — 61,821 — 61,821 December 31, 2023 Fair Value Measurements Using Level 1 Level 2 Level 3 Total (In Thousands) Assets: Securities available-for-sale: U.S. treasuries $ — $ 13,776 $ — $ 13,776 U.S. government agency securities - government-sponsored — 27,566 — 27,566 Municipal securities — 35,881 — 35,881 Residential mortgage-backed securities - government issued — 68,056 — 68,056 Residential mortgage-backed securities - government- — 120,833 — 120,833 Commercial mortgage-backed securities - government issued — 2,525 — 2,525 Commercial mortgage-backed securities - government- — 28,369 — 28,369 Interest rate swaps — 55,597 — 55,597 Liabilities: Interest rate swaps — 51,949 — 51,949 For assets and liabilities measured at fair value on a recurring basis, there were no transfers between the levels during the three and six months ended June 30, 2024 or the year ended December 31, 2023 related to the above measurements. Assets and liabilities measured at fair value on a no n-recurring basis, segregated by fair value hierarchy are summarized below: June 30, 2024 Fair Value Measurements Using Level 1 Level 2 Level 3 Total (In Thousands) Collateral-dependent loans $ — $ — $ 5,055 $ 5,055 Repossessed assets — — 54 54 Loan servicing rights — — 1,173 1,173 December 31, 2023 Fair Value Measurements Using Level 1 Level 2 Level 3 Total (In Thousands) Collateral-dependent loans $ — $ — $ 4,917 $ 4,917 Repossessed assets — — 247 247 Loan servicing rights — — 1,356 1,356 Collateral-dependent loans were written down to the fair value of their underlying collateral less costs to sell of $ 5.1 million and $ 4.9 million at June 30, 2024 and December 31, 2023 , respectively, through the establishment of specific reserves or by recording charge-offs when the carrying value exceeded the fair value of the underlying collateral of individually evaluated loans. Valuation techniques consistent with the market approach, income approach, or cost approach were used to measure fair value. These techniques included observable inputs for the collateral dependent loans being evaluated, such as current appraisals, recent sales of similar assets, or other observable market data, and u no bservable inputs, typically when discounts are applied to appraisal values to adjust such values to current market conditions or to reflect net realizable values. The quantification of unobservable inputs for Level 3 individually evaluated loan values range from 10 % - 100 % as of the measurement date of June 30, 2024. The weighted average of those unobservable inputs was 42 % . The majority of the individually evaluated loans are considered collateral dependent loans or are supported by an SBA guaranty. Repossessed assets are measured and reported at fair value through a charge-off to the allowance for credit losses, if deemed necessary. The fair value of a repossessed asset, upon initial recognition, is estimated using a market approach or based on observable market data, such as a current appraisal, recent sale price of similar assets, or based upon assumptions specific to the individual property or equipment, such as management applied discounts used to further reduce values to a net realizable value when observable inputs become stale. Loan servicing rights represent the asset retained upon sale of the guaranteed portion of certain SBA loans. When SBA loans are sold, servicing rights are initially recorded at fair value with the income statement effect recorded in gains on sales of loans. The servicing rights are subsequently measured using the amortization method, which requires amortization into interest income in proportion to, and over the period of, the estimated future net servicing income of the underlying loans. The Corporation periodically reviews this portfolio for impairment and engages a third-party valuation firm to assess the fair value of the overall servicing rights portfolio. Loan servicing rights do not trade in an active, open market with readily observable prices. While sales of loan servicing rights do occur, the precise terms and conditions typically are not readily available to allow for a “quoted price for similar assets” comparison. Accordingly, the Corporation utilizes an independent valuation from a third party which uses a discounted cash flow model to estimate the fair value of its loan servicing rights. The valuation model incorporates prepayment assumptions to project loan servicing rights cash flows based on the current interest rate scenario, which is then discounted to estimate an expected fair value of the loan servicing rights. The valuation model considers portfolio characteristics of the underlying serviced portion of the SBA loans and uses the following significant unobservable inputs: (1) constant prepayment rate (“CPR”) assumptions based on the SBA sold pools historical CPR as quoted in Bloomberg and (2) a discount rate. Due to the nature of the valuation inputs, loan servicing rights are classified in Level 3 of the fair value hierarchy. Fair Value of Financial Instruments The Corporation is required to disclose estimated fair values for its financial instruments. Fair value estimates, methods, and assumptions, consistent with exit price concepts for fair value measurements, are set forth below: June 30, 2024 Carrying Fair Value Total Level 1 Level 2 Level 3 (In Thousands) Financial assets: Cash and cash equivalents $ 81,080 $ 81,080 $ 81,080 $ — $ — Securities available-for-sale 308,852 308,852 — 308,852 — Securities held-to-maturity 7,082 6,786 — 6,786 — Loans held for sale 6,507 7,027 — 7,027 — Loans and lease receivables, net 2,952,326 2,934,670 — — 2,934,670 Federal Home Loan Bank stock 11,901 N/A N/A N/A N/A Accrued interest receivable 13,639 13,639 13,639 — — Interest rate swaps 70,773 70,773 — 70,773 — Financial liabilities: — Deposits 2,885,183 2,882,318 2,240,520 641,798 — Federal Home Loan Bank advances and other borrowings 327,855 321,688 — 321,688 — Accrued interest payable 11,290 11,290 11,290 — — Interest rate swaps 61,821 61,821 — 61,821 — Off-balance sheet items: Standby letters of credit 141 141 — — 141 N/A = The fair value is not applicable due to restrictions placed on transferability December 31, 2023 Carrying Fair Value Total Level 1 Level 2 Level 3 (In Thousands) Financial assets: Cash and cash equivalents $ 139,510 $ 139,510 $ 139,510 $ — $ — Securities available-for-sale 297,006 297,006 — 297,006 — Securities held-to-maturity 8,503 8,255 — 8,255 — Loans held for sale 4,589 4,956 — 4,956 — Loans and lease receivables, net 2,818,986 2,789,731 — — 2,789,731 Federal Home Loan Bank stock 12,042 N/A N/A N/A N/A Accrued interest receivable 13,275 13,275 13,275 — — Interest rate swaps 55,597 55,597 — 55,597 — Financial liabilities: Deposits 2,796,779 2,795,463 2,101,939 693,524 — Federal Home Loan Bank advances and other borrowings 330,916 320,287 — 320,287 — Accrued interest payable 10,860 10,860 10,860 — — Interest rate swaps 51,949 51,949 — 51,949 — Off-balance sheet items: Standby letters of credit 190 190 — — 190 N/A = The fair value is not applicable due to restrictions placed on transferability Disclosure of fair value information about financial instruments, for which it is practicable to estimate that value, is required whether or not recognized in the unaudited Consolidated Balance Sheets. In cases where quoted market prices are not available, fair values are based on estimates using present value or other valuation techniques. Those techniques are significantly affected by the assumptions used, including the discount rate and estimates of future cash flows. In that regard, the derived fair value estimates cannot be substantiated by comparison to independent markets and, in many cases, could not be realized in immediate settlement of the instruments. Certain financial instruments and all non-financial instruments are excluded from the disclosure requirements. Accordingly, the aggregate fair value amounts presented do not necessarily represent the underlying value of the Corporation. Securities: The fair value measurements of investment securities are determined by a third-party pricing service which considers observable data that may include dealer quotes, market spreads, cash flows, the U.S. Treasury yield curve, trade execution data, market consensus prepayment speeds, credit information, and the securities’ terms and conditions, among other things. The fair value measurements are subject to independent verification by another pricing source on a quarterly basis to review for reasonableness. Any significant differences in pricing are reviewed with appropriate members of management who have the relevant technical expertise to assess the results. The Corporation has determined that these valuations are classified in Level 2 of the fair value hierarchy. When the independent pricing service does not provide a fair value measurement for a particular security, the Corporation will estimate the fair value based on specific information about each security. Fair values derived in this manner are classified in Level 3 of the fair value hierarchy. Loans Held for Sale: Loans held for sale, which consist of the guaranteed portions of SBA 7(a) loans, are carried at the lower of cost or estimated fair value. The estimated fair value is based on what secondary markets are currently offering for portfolios with similar characteristics. Derivatives: The carrying amount and fair value of existing derivative financial instruments are based upon independent valuation models, which use widely accepted valuation techniques, including discounted cash flow analysis on the expected cash flows of each derivative contract. This analysis reflects the contractual terms of the derivatives, including the period to maturity, and uses observable market-based inputs, including interest rate curves and implied volatilities. The Corporation incorporates credit valuation adjustments to appropriately reflect both its own nonperformance risk and the respective counterparty’s nonperformance risk in the fair value measurements. In adjusting the fair value of its derivative contracts for the effect of nonperformance risk, the Corporation considers the impact of netting and any applicable credit enhancements, such as collateral postings, thresholds, mutual puts, and guarantees. Limitations: Fair value estimates are made at a discrete point in time, based on relevant market information and information about the financial instrument. These estimates do not reflect any premium or discount that could result from offering for sale at one time the Corporation’s entire holding of a particular financial instrument. Because no market exists for a significant portion of the Corporation’s financial instruments, fair value estimates are based on judgments regarding future expected loss experience, current economic conditions, risk characteristics of various financial instruments, and other factors. These estimates are subjective in nature and involve uncertainties and matters of significant judgment and, therefore, cannot be determined with precision. Changes in assumptions could significantly affect the estimates. Fair value estimates are based on existing balance sheet financial instruments without attempting to estimate the value of anticipated future business and the value of assets and liabilities that are not considered financial instruments. In addition, the tax ramifications related to the realization of the unrealized gains and losses can have a significant effect on fair value estimates and are not considered in the estimates.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Financial Instruments	Note 13 — Derivative Financial Instruments The Corporation offers interest rate swap products directly to qualified commercial borrowers. The Corporation economically hedges client derivative transactions by entering into offsetting interest rate swap contracts executed with a third party. Derivative transactions executed as part of this program are not considered hedging instruments and are marked-to-market through earnings each period. The derivative contracts have mirror-image terms, which results in the positions’ changes in fair value offsetting through earnings each period. The credit risk and risk of non-performance embedded in the fair value calculations is different between the dealer counterparties and the commercial borrowers which may result in a difference in the changes in the fair value of the mirror-image swaps. The Corporation incorporates credit valuation adjustments to appropriately reflect both its own non-performance risk and the counterparty’s risk in the fair value measurements. When evaluating the fair value of its derivative contracts for the effects of non-performance and credit risk, the Corporation considered the impact of netting and any applicable credit enhancements such as collateral postings, thresholds, and guarantees. As of June 30, 2024 and December 31, 2023, the credit valuation allowance was $ 38,000 and $ 117,000 , respectively. The Corporation receives fixed rates and pays floating rates based upon designated benchmark interest rates used on the swaps with commercial borrowers. Commercial borrower swaps are completed independently with each borrower and are not subject to master netting arrangements. The Corporation pays fixed rates and receives floating rates based upon designated benchmark interest rates used on the swaps with dealer counterparties. Dealer counterparty swaps are subject to master netting agreements among the contracts within our Bank and are reported on the unaudited Consolidated Balance Sheet. The gross amount of dealer counterparty swaps, without regard to the enforceable master netting agreement, was a gross derivative asset of $ 61.8 million and gross derivative liability of $ 2.1 million as of June 30, 2024. All changes in fair value of these instruments are recorded in other non-interest income. Given the mirror-image terms of the outstanding derivative portfolio, the change in fair value for the three and six months ended June 30, 2024 and 2023 had an insignificant impact on the unaudited Consolidated Statements of Income. The Corporation also enters into interest rate swaps to manage interest rate risk and reduce the cost of match-funding certain long-term fixed rate loans. These derivative contracts involve the receipt of floating rate interest from a counterparty in exchange for the Corporation making fixed-rate payments over the life of the agreement, without the exchange of the underlying notional value. The instruments are designated as cash flow hedges as the receipt of floating rate interest from the counterparty is used to manage interest rate risk related to cash outflows attributable to future wholesale deposit or short-term FHLB advance borrowings. The change in the fair value of these hedging instruments is recorded in accumulated other comprehensive income and is subsequently reclassified into earnings in the period that the hedged transactions affect earnings. A pre-tax unrealized gain of $ 300,000 and $ 5.1 million was recognized in other comprehensive income for the three and six months ended June 30, 2024 , respectively, and there were no ineffective portions of the hedges. A pre-tax unrealized gain of $ 3.6 million and $ 2.2 million was recognized in other comprehensive income for the three and six months ended June 30, 2023 , respectively, and there were no ineffective portions of the hedges. The Corporation also enters into interest rate swaps to mitigate market value volatility on certain long-term fixed securities. The objective of the hedge is to protect the Corporation against changes in fair value due to changes in benchmark interest rates. The instruments are designated as fair value hedges as the changes in the fair value of the interest rate swap are expected to offset changes in the fair value of the hedged item attributable to changes in the SOFR swap rate, the designated benchmark interest rate. These derivative contracts involve the receipt of floating rate interest from a counterparty in exchange for the Corporation making fixed-rate payments over the life of the agreement, without the exchange of the underlying notional value. The change in the fair value of these hedging instruments is recorded in accumulated other comprehensive income and is subsequently reclassified into earnings in the period that the hedged transactions affect earnings. A pre-tax unrealized gain of $ 82,000 and $ 223,000 was recognized in other comprehensive income for the three and six months ended June 30, 2024 , respectively, and there was no ineffective portion of these hedges. A pre-tax unrealized gain of $ 107,000 and a pre-tax unrealized loss of $ 68,000 was recognized in other comprehensive income for the three and six months ended June 30, 2023 , respectively, and there was no ineffective portion of these hedges. As of June 30, 2024 Number of Notional Weighted Fair (Dollars in Thousands) Included in Derivative assets Derivatives not designated as hedging instruments Interest rate swap agreements on loans with commercial 15 $ 148,971 5.56 $ 2,146 Interest rate swap agreements on loans with third-party 104 962,598 5.57 59,628 Derivatives designated as hedging instruments Interest rate swap related to AFS securities 11 $ 12,500 7.78 $ 847 Interest rate swap related to wholesale funding 32 337,655 4.04 8,152 Included in Derivative liabilities Derivatives not designated as hedging instruments Interest rate swap agreements on loans with commercial 89 $ 813,628 5.58 $ 61,775 Derivatives designated as hedging instruments Interest rate swap related to wholesale funding 10 $ 100,000 2.09 $ 46 As of December 31, 2023 Number of Notional Weighted Fair (Dollars in Thousands) Included in Derivative assets Derivatives not designated as hedging instruments Interest rate swap agreements on loans with commercial 25 $ 249,454 6.33 $ 7,904 Interest rate swap agreements on loans with third-party 106 939,156 6.06 43,234 Derivatives designated as hedging instruments Interest rate swap related to AFS securities 11 $ 12,500 8.28 $ 624 Interest rate swap related to wholesale funding 9 96,400 2.47 3,835 Included in Derivative liabilities Derivatives not designated as hedging instruments Interest rate swap agreements on loans with commercial 81 $ 689,702 5.96 $ 51,138 Derivatives designated as hedging instruments Interest rate swap related to wholesale funding 29 $ 306,255 3.89 $ 811

Regulatory Capital

Broker-Dealer, Net Capital Requirement, SEC Regulation [Abstract]
Regulatory Capital	Note 14 — Regulatory Capital The Corporation and the Bank are subject to various regulatory capital requirements administered by Federal and Wisconsin banking agencies. Failure to meet minimum capital requirements can result in certain mandatory, and possibly additional discretionary actions on the part of regulators, that if undertaken, could have a direct material effect on the Bank’s assets, liabilities, and certain off-balance sheet items as calculated under regulatory practices. The Corporation’s and the Bank’s capital amounts and classifications are also subject to qualitative judgments by the regulators about components, risk weightings, and other factors. The Corporation regularly reviews and updates, when appropriate, its Capital and Liquidity Action Plans, which is designed to help ensure appropriate capital adequacy, to plan for future capital needs, and to ensure that the Corporation serves as a source of financial strength to the Bank. The Corporation’s and the Bank’s Board and management teams adhere to the appropriate regulatory guidelines on decisions which affect their respective capital positions, including but not limited to, decisions relating to the payment of dividends and increasing indebtedness. As a bank holding company, the Corporation’s ability to pay dividends is affected by the policies and enforcement powers of the Board of Governors of the Federal Reserve system (the “Federal Reserve”). Federal Reserve guidance urges financial institutions to strongly consider eliminating, deferring, or significantly reducing dividends if: (i) net income available to common shareholders for the past four quarters, net of dividends previously paid during that period, is not sufficient to fully fund the dividend; (ii) the prospective rate of earnings retention is not consistent with the bank holding company’s capital needs and overall current and prospective financial condition; or (iii) the bank holding company will not meet, or is in danger of not meeting, its minimum regulatory capital ratios. Management intends, when appropriate under regulatory guidelines, to consult with the Federal Reserve Bank (“FRB”) of Chicago and provide it with information on the Corporation’s then-current and prospective earnings and capital position in advance of declaring any cash dividends. As a Wisconsin corporation, the Corporation is subject to the limitations of the Wisconsin Business Corporation Law, which prohibit the Corporation from paying dividends if such payment would: (i) render the Corporation unable to pay its debts as they become due in the usual course of business, or (ii) result in the Corporation’s assets being less than the sum of its total liabilities plus the amount needed to satisfy the preferential rights upon dissolution of any shareholders with preferential rights superior to those shareholders receiving the dividend. The Bank is also subject to certain legal, regulatory, and other restrictions on their ability to pay dividends to the Corporation. As a bank holding company, the payment of dividends by the Bank to the Corporation is one of the sources of funds the Corporation could use to pay dividends, if any, in the future and to make other payments. Future dividend decisions by the Bank and the Corporation will continue to be subject to compliance with various legal, regulatory, and other restrictions as defined from time to time. Quantitative measures established by regulation to ensure capital adequacy require the Corporation and the Bank to maintain minimum amounts and ratios of Total Common Equity Tier 1 and Tier 1 capital to risk-weighted assets and of Tier 1 capital to adjusted total assets. These risk-based capital requirements presently address credit risk related to both recorded and off-balance sheet commitments and obligations. As of June 30, 2024 , the Corporation’s capital levels exceeded the regulatory minimums and the Bank’s capital levels remained characterized as well capitalized under the regulatory framework. The following tables summarize both the Corporation’s and the Bank’s capital ratios and the ratios required by their federal regulators: As of June 30, 2024 Actual (1) Minimum Required For Capital Minimum Required Amount Ratio Amount Ratio Amount Ratio Amount Ratio (Dollars in Thousands) Total capital Consolidated $ 392,359 11.45 % $ 274,074 8.00 % $ 359,722 10.50 % N/A N/A First Business Bank 392,709 11.46 274,045 8.00 359,684 10.50 $ 342,556 10.00 % Tier 1 capital Consolidated $ 307,878 8.99 % $ 205,556 6.00 % $ 291,204 8.50 % N/A N/A First Business Bank 357,723 10.44 205,534 6.00 291,173 8.50 $ 274,045 8.00 % Common equity tier 1 capital Consolidated $ 295,886 8.64 % $ 154,167 4.50 % $ 239,815 7.00 % N/A N/A First Business Bank 357,723 10.44 154,150 4.50 239,789 7.00 $ 222,662 6.50 % Tier 1 leverage capital Consolidated $ 307,878 8.51 % $ 144,664 4.00 % $ 144,664 4.00 % N/A N/A First Business Bank 357,723 9.89 144,682 4.00 144,682 4.00 $ 180,852 5.00 % As of December 31, 2023 Actual (1) Minimum Required For Capital Minimum Required Amount Ratio Amount Ratio Amount Ratio Amount Ratio (Dollars in Thousands) Total capital Consolidated $ 375,440 11.19 % $ 268,500 8.00 % $ 352,406 10.50 % N/A N/A First Business Bank 376,310 11.21 268,595 8.00 352,531 10.50 $ 335,744 10.00 % Tier 1 capital Consolidated $ 293,338 8.74 % $ 201,375 6.00 % $ 285,281 8.50 % N/A N/A First Business Bank 343,604 10.23 201,446 6.00 285,382 8.50 $ 268,595 8.00 % Common equity tier 1 capital Consolidated $ 281,346 8.38 % $ 151,031 4.50 % $ 234,937 7.00 % N/A N/A First Business Bank 343,604 10.23 151,085 4.50 235,021 7.00 $ 218,233 6.50 % Tier 1 leverage capital Consolidated $ 293,338 8.43 % $ 139,145 4.00 % $ 139,145 4.00 % N/A N/A First Business Bank 343,604 9.87 139,262 4.00 139,262 4.00 $ 174,077 5.00 % (1) 2024 and 2023 capital amounts include $677,000 and $1.0 million, respectively, of additional stockholders’ equity as elected by the Corporation and permitted by federal banking regulatory agencies related to the adoption of ASC 326.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	Basis of Presentation The accompanying unaudited Consolidated Financial Statements were prepared in accordance with GAAP and the instructions to Form 10-Q and Rule 10-01 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by GAAP for complete financial statements and should be read in conjunction with the Corporation’s Consolidated Financial Statements and footnotes thereto included in the Corporation’s Annual Report on Form 10-K for the year ended December 31, 2023.
Principles of Consolidation	The unaudited Consolidated Financial Statements include the accounts of the Corporation and its wholly-owned subsidiaries. All significant intercompany balances and transactions have been eliminated in consolidation.
Use of Estimates	Management of the Corporation is required to make estimates and assumptions which affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements as well as reported amounts of revenues and expenses during the reporting period. Actual results could differ significantly from those estimates. Material estimates that could significantly change in the near-term include the value of securities and interest rate swaps, level of the allowance for credit losses, lease residuals, property under operating leases, goodwill, and income taxes
Reclassification	Certain amounts in prior periods may have been reclassified to conform to the current presentation.
Subsequent Events	Subsequent events have been evaluated through the date of the issuance of the unaudited Consolidated Financial Statements. No significant subsequent events have occurred through this date requiring adjustment to the financial statements or disclosures.
Recent Accounting Pronouncements	Recent Accounting Pronouncements In November 2023, the FASB issued ASU No. 2023-07, “Segment Reporting (Topic 820): Improvements to Reportable Segment Disclosures.” This update is intended to improve reportable segment disclosure requirements, primarily through enhanced disclosures about significant segment expenses. This update is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2024. The Corporation is one operating segment; therefore, we do not anticipate any impact to the financial statements. In December 2023, the FASB issued ASU No. 2023-09, “Income Taxes (Topic 740): Improvements to Income Tax Disclosures.” This update enhances the transparency and decision usefulness of income tax disclosures by providing better information regarding exposure to potential changes in jurisdictional tax legislation and related forecasting and cash flow opportunities. This update is effective for fiscal years beginning after December 15, 2024. The Corporation is assessing the impact of the standard.
Loans and Leases Receivable, Allowance for Credit Losses	Allowance for Credit Losses The ACL is an estimate of the expected credit losses on financial assets measured at amortized cost, which is measured using relevant information about past events, including historical credit loss experience on financial assets with similar risk characteristics, current conditions, and reasonable and supportable forecasts that affect the collectability of the remaining cash flows over the contractual term of the financial assets. A provision for credit losses is charged to operations based on management’s periodic evaluation of these and other pertinent factors as discussed within Note 1 – Nature of Operations and Summary of Significant Accounting Policies included in the Corporation’s Form 10-K for the year ended December 31, 2023. Quantitative Considerations The ACL is primarily calculated utilizing a discounted cash flow (“DCF”) model. Key inputs and assumptions used in this model are discussed below: • Forecast model - For each portfolio segment, a loss driver analysis (“LDA”) was performed in order to identify appropriate loss drivers and create a regression model for use in forecasting cash flows. The LDA analysis utilized peer FFIEC Call Report data for all pools. The Corporation plans to update the LDA annually. • Probability of default ("PD") – PD is the probability that an asset will be in default within a given time frame. The Corporation has defined default as when a charge-off has occurred, a loan goes to non-accrual status, or a loan is greater than 90 days past due. The forecast model is utilized to estimate PDs. • Loss given default ("LGD") – LGD is the percentage of the asset not expected to be collected due to default. The LGD is derived from using a method referred to as Frye Jacobs which uses industry data. • Prepayments and curtailments – Prepayments and curtailments are calculated based on the Corporation’s own data. This analysis is updated semi-annually. • Forecast and reversion – The Corporation has established a one-year reasonable and supportable forecast period with a one-year straight line reversion to the long-term historical average. • Economic forecast – The Corporation utilizes a third party to provide economic forecasts under various scenarios, which are assessed against economic indicators and management’s observations in the market. As of December 31, 2023, the Corporation selected a forecast which estimates unemployment between 3.89% and 4.04% and GDP growth change between 1.29% and 2.32% over the next four quarters. As of June 30, 2024, the Corporation selected a forecast which estimates unemployment between 4.06% and 4.08% and GDP growth change between 1.76% and 2.21% over the next four quarters. Following the forecast period, the model reverts to long-term averages over four quarters. Management believes that the resulting quantitative reserve appropriately balances economic indicators with identified risks. Qualitative Considerations In addition to the quantitative model, management considers the need for qualitative adjustment for risks not considered in the DCF. Factors that are considered by management in determining loan collectability and the appropriate level of the ACL are listed below: • The Corporation’s lending policies and procedures, including changes in lending strategies, underwriting standards and practices for collections, write-offs, and recoveries; • Actual and expected changes in international, national, regional, and local economic and business conditions and developments in which the Corporation operates that affect the collectability of financial assets; • The experience, ability, and depth of the Corporation’s lending, investment, collection, and other relevant management and staff; • The volume of past due financial assets, the volume of non-accrual loans and leases, and the volume and severity of adversely classified or graded assets; • The existence and effect of industry concentrations of credit; • The nature and volume of the portfolio segment or class; • The quality of the Corporation’s credit function; and • The effect of other external factors such as the regulatory, legal and technological environments, competition, and events such as natural disasters or pandemics.
Fair Value of Financial Instruments	The Corporation determines the fair values of its financial instruments based on the fair value hierarchy established in ASC Topic 820, which requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. Fair value is defined as the price that would be received in an orderly transaction that is not a forced liquidation or distressed sale at the measurement date and is based on exit prices. Fair value includes assumptions about risk, such as nonperformance risk in liability fair values, and is a market-based measurement, not an entity-specific measurement. The standard describes three levels of inputs that may be used to measure fair value. Level 1 — Level 1 inputs are unadjusted quoted prices in active markets for identical assets or liabilities that the Corporation has the ability to access at the measurement date. Level 2 — Level 2 inputs are inputs, other than quoted prices included with Level 1, that are observable for the asset or liability either directly or indirectly, such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities. Level 3 — Level 3 inputs are supported by little or no market activity and are significant to the fair value of the assets or liabilities. In instances where the determination of the fair value measurement is based on inputs from different levels of the fair value hierarchy, the level in the fair value hierarchy within which the entire fair value measurement falls is based on the lowest level input that is significant to the fair value measurement in its entirety. The Corporation’s assessment of the significance of a particular input to the fair value measurement in its entirety requires judgment and considers factors specific to the asset or liability.
Fair Value Measurement	Disclosure of fair value information about financial instruments, for which it is practicable to estimate that value, is required whether or not recognized in the unaudited Consolidated Balance Sheets. In cases where quoted market prices are not available, fair values are based on estimates using present value or other valuation techniques. Those techniques are significantly affected by the assumptions used, including the discount rate and estimates of future cash flows. In that regard, the derived fair value estimates cannot be substantiated by comparison to independent markets and, in many cases, could not be realized in immediate settlement of the instruments. Certain financial instruments and all non-financial instruments are excluded from the disclosure requirements. Accordingly, the aggregate fair value amounts presented do not necessarily represent the underlying value of the Corporation. Securities: The fair value measurements of investment securities are determined by a third-party pricing service which considers observable data that may include dealer quotes, market spreads, cash flows, the U.S. Treasury yield curve, trade execution data, market consensus prepayment speeds, credit information, and the securities’ terms and conditions, among other things. The fair value measurements are subject to independent verification by another pricing source on a quarterly basis to review for reasonableness. Any significant differences in pricing are reviewed with appropriate members of management who have the relevant technical expertise to assess the results. The Corporation has determined that these valuations are classified in Level 2 of the fair value hierarchy. When the independent pricing service does not provide a fair value measurement for a particular security, the Corporation will estimate the fair value based on specific information about each security. Fair values derived in this manner are classified in Level 3 of the fair value hierarchy. Loans Held for Sale: Loans held for sale, which consist of the guaranteed portions of SBA 7(a) loans, are carried at the lower of cost or estimated fair value. The estimated fair value is based on what secondary markets are currently offering for portfolios with similar characteristics. Derivatives: The carrying amount and fair value of existing derivative financial instruments are based upon independent valuation models, which use widely accepted valuation techniques, including discounted cash flow analysis on the expected cash flows of each derivative contract. This analysis reflects the contractual terms of the derivatives, including the period to maturity, and uses observable market-based inputs, including interest rate curves and implied volatilities. The Corporation incorporates credit valuation adjustments to appropriately reflect both its own nonperformance risk and the respective counterparty’s nonperformance risk in the fair value measurements. In adjusting the fair value of its derivative contracts for the effect of nonperformance risk, the Corporation considers the impact of netting and any applicable credit enhancements, such as collateral postings, thresholds, mutual puts, and guarantees. Limitations: Fair value estimates are made at a discrete point in time, based on relevant market information and information about the financial instrument. These estimates do not reflect any premium or discount that could result from offering for sale at one time the Corporation’s entire holding of a particular financial instrument. Because no market exists for a significant portion of the Corporation’s financial instruments, fair value estimates are based on judgments regarding future expected loss experience, current economic conditions, risk characteristics of various financial instruments, and other factors. These estimates are subjective in nature and involve uncertainties and matters of significant judgment and, therefore, cannot be determined with precision. Changes in assumptions could significantly affect the estimates. Fair value estimates are based on existing balance sheet financial instruments without attempting to estimate the value of anticipated future business and the value of assets and liabilities that are not considered financial instruments. In addition, the tax ramifications related to the realization of the unrealized gains and losses can have a significant effect on fair value estimates and are not considered in the estimates.

Earnings Per Common Share (Poli

Earnings Per Common Share (Policies)	6 Months Ended

Earnings Per Share [Abstract]
Earnings Per Share	Earnings per common share are computed using the two-class method. Basic earnings per common share are computed by dividing net income allocated to common shares by the weighted-average number of shares outstanding during the applicable period, excluding outstanding participating securities. Participating securities include unvested restricted shares. Unvested restricted shares are considered participating securities because holders of these securities receive non-forfeitable dividends, or dividend equivalents, at the same rate as holders of the Corporation’s common stock. Diluted earnings per share are computed by dividing net income allocated to common shares adjusted for reallocation of undistributed earnings of unvested restricted shares by the weighted average number of shares determined for the basic earnings per common share computation plus the dilutive effect of common stock equivalents using the treasury stock method.

Share-Based Payment Arrangement [Abstract]
Share-based Compensation, Option and Incentive Plans	The Corporation initially adopted the 2019 Equity Incentive Plan (the “Plan”) during the quarter ended June 30, 2019. The Plan is administered by the Compensation Committee of the Board of Directors (the “Board”) of the Corporation and provides for the grant of equity ownership opportunities through incentive stock options and nonqualified stock options, restricted stock, restricted stock units, dividend equivalent units, and any other type of award permitted by the Plan. As of June 30, 2024, 267,882 shares were available for future grants under the Plan, as amended. Shares covered by awards that expire, terminate, or lapse will again be available for the grant of awards under the Plan. Restricted Stock Under the Plan, the Corporation may grant restricted stock awards (“RSA”), restricted stock units (“RSU”), and other stock-based awards to plan participants, subject to forfeiture upon the occurrence of certain events until the dates specified in the participant’s award agreement. While restricted stock is subject to forfeiture, RSA participants may exercise full voting rights and will receive all dividends and other distributions paid with respect to the restricted shares. RSUs do not have voting rights. RSUs granted prior to 2023 are provided dividend equivalents concurrent with dividends paid to shareholders while RSUs granted in 2023 and after will accrue dividend equivalents payable upon vesting. The restricted stock granted under the Plan is typically subject to a vesting period. Compensation expense for restricted stock is recognized over the requisite service period of generally three or four years for the entire award on a straight-line basis. Upon vesting of restricted stock, the benefit of tax deductions in excess of recognized compensation expense is reflected as an income tax benefit in the unaudited Consolidated Statements of Income. The Corporation may also issue performance-based restricted stock units (“PRSU”). Vesting of the PRSU will be measured on the relative Total Shareholder Return (“TSR”) and relative Return on Average Equity (“ROAE”) for issuances prior to 2023 or Return on Average Common Equity (“ROACE”) for issuances after 2022, and will cliff-vest after a three-year measurement period based on the Corporation’s TSR performance and ROAE or ROACE performance compared to a broad peer group of over 100 banks. At the end of the performance period, the number of actual shares to be awarded varies between 0 % and 200 % of target amounts. The restricted stock awards and units issued to executive officers will vest ratably over a three-year period. Compensation expense is recognized for PRSU over the requisite service and performance period of generally three years for the entire expected award on a straight-line basis. The compensation expense for the awards expected to vest for the percentage of performance-based restricted stock units subject to the ROAE or ROACE metric will be adjusted if there is a change in the expectation of ROAE or ROACE. The compensation expense for the awards expected to vest for the percentage of PRSU subject to the TSR metric are never adjusted and are amortized utilizing the accounting fair value provided using a Monte Carlo pricing model.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivatives	The Corporation offers interest rate swap products directly to qualified commercial borrowers. The Corporation economically hedges client derivative transactions by entering into offsetting interest rate swap contracts executed with a third party. Derivative transactions executed as part of this program are not considered hedging instruments and are marked-to-market through earnings each period. The derivative contracts have mirror-image terms, which results in the positions’ changes in fair value offsetting through earnings each period. The credit risk and risk of non-performance embedded in the fair value calculations is different between the dealer counterparties and the commercial borrowers which may result in a difference in the changes in the fair value of the mirror-image swaps. The Corporation incorporates credit valuation adjustments to appropriately reflect both its own non-performance risk and the counterparty’s risk in the fair value measurements. When evaluating the fair value of its derivative contracts for the effects of non-performance and credit risk, the Corporation considered the impact of netting and any applicable credit enhancements such as collateral postings, thresholds, and guarantees. As of June 30, 2024 and December 31, 2023, the credit valuation allowance was $ 38,000 and $ 117,000 , respectively.
