(the “Bank”). The Bank operates as a full-service financial institution with a primary market area including, but not limited to, the counties in which the Bank’s branches are located. The Bank has twenty-six locations located in Manitowoc, Outagamie, Brown, Winnebago, Sheboygan, Shawano, Waupaca, Ozaukee, Monroe, Fond du Lac, Waushara, Dane, Columbia and Jefferson counties in Wisconsin. The Company and Bank are subject to the regulations of certain federal agencies and undergo periodic examinations by those regulatory authorities. These interim unaudited consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the United States of America (“GAAP”) for interim financial information and with the instructions to Quarterly Report on Form 10-Q and Article 10 of Regulation S-X. Accordingly, certain information and footnote disclosures required by GAAP have been omitted or abbreviated. These unaudited consolidated financial statements should be read in conjunction with the Company’s audited consolidated financial statements and footnotes included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2024 (“Annual Report”). The unaudited consolidated financial statements include all adjustments, consisting of normal recurring adjustments, necessary for a fair presentation of the results for the interim periods. The results for interim periods are not necessarily indicative of results for a full year. Critical Accounting Policies and Estimates The accounting and reporting policies of the Company conform to GAAP in the United States and general practices within the financial institution industry. To prepare financial statements in conformity with GAAP, management makes estimates, assumptions and judgments based on available information. These estimates, assumptions and judgments are based on information available as of the date of the financial statements and, as this information changes, actual results could differ from the estimates, assumptions and judgments reflected in the financial statement. As disclosed in the Company’s Annual Report, management has identified several accounting policies that, due to the estimates, assumptions and judgments inherent in those policies, are critical in understanding our financial statements. These include accounting for business combinations (primarily related to core deposit intangibles and acquired loans) and accounting for the ACL-Loans. ​ There have been no material changes or developments with respect to the assumptions or methodologies that the Company uses when applying what management believes are critical accounting policies and developing critical accounting estimates as previously disclosed in the Company’s Annual Report. Recently Issued Not Yet Effective Accounting Standards In October 2023, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2023-06, Disclosure Improvements. This ASU modifies the disclosure or presentation requirements of a variety of Topics in the Codification. The amendments in this ASU are expected to clarify or improve disclosure and presentation requirements for certain codification topics. The effective date for each amendment will be the date on which the Security and Exchange Commission’s removal of that related disclosure from Regulation S-X or Regulation S-K becomes effective, with early adoption prohibited. If, by June 30, 2027, the Securities and Exchange Commission has not removed the applicable requirement from Regulation S-X or Regulation S-K, the pending content of the related amendment will be removed from the Codification and will not become effective for any entity. The Company does not anticipate a significant impact to its financial statement disclosures as a result of this ASU. 9 Table of Contents ​ In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures. This ASU is intended to improve the transparency and decision usefulness of income tax disclosures by requiring specific categories in the rate reconciliation table and disaggregation of taxes paid by jurisdiction. All public entities must also provide additional information for reconciling items that meet a specific quantitative threshold. This update is effective for annual periods beginning after December 15, 2024. The Company anticipates that this standard will require expanded disclosure related to its income tax exposure, but will not cause any change in the accounting for operational results. In November 2024, the FASB issued ASU 2024-03, Income Statement – Reporting Comprehensive Income – Expense Disaggregation Disclosures (Topic 220): Disaggregation of Income Statement Expenses. This ASU is intended to improve the disclosures about a public entity’s income statement expense categories and addresses requests from investors and other decision makers for additional, more detailed information about income statement expense categories. The amendment applies to all public entities that are required to report income statement categories in accordance with Topic 280. The effective date for this update was amended by ASU 2025-01, Income Statement – Reporting Comprehensive Income – Expense Disaggregation Disclosures (Subtopic 220-40): Clarifying the Effective Date, and is now effective for annual periods beginning after December 15, 2026, and interim reporting periods within annual reporting periods beginning after December 15, 2027. ​ ​ ​ NOTE 2 – EARNINGS PER SHARE The two-class method is used in the calculation of basic and diluted earnings per share. Under the two-class method, earnings available to common shareholders for the period are allocated between common shareholders and participating securities according to dividends declared (or accumulated) and participation rights in undistributed earnings. There were no anti-dilutive stock options for the three months ended March 31, 2025 or 2024.

This is based on the Company’s analysis of the risk characteristics, including credit ratings, and other qualitative factors related to these securities. The issuers of these securities continue to make timely principal and interest payments under the contractual terms of the securities. As of March 31, 2025, the Company did not intend to sell these securities and it was more likely than not that the Company would not be required to sell the debt securities before recovery of their amortized cost, which may be at maturity. The unrealized losses have occurred as a result of changes in interest rates, market spreads and market conditions subsequent to purchase, not credit deterioration. Furthermore, based on its analysis the Company has determined that held to maturity securities have zero expected credit losses. U.S. Treasury securities have the full faith and credit backing of the United States Government. 12 Table of Contents ​ The following is a summary of amortized cost and estimated fair value of securities by contractual maturity as of March 31, 2025.

Sales of securities available for sale produced $ 10.2 million in proceeds with immaterial gross losses for the three months ended March 31, 2024. ​ NOTE 4 – LOANS, ALLOWANCE FOR CREDIT LOSSES, AND CREDIT QUALITY The following table presents total loans by portfolio segment and class of loan as of March 31, 2025 and December 31, 2024: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ 2025 2024 Commercial/industrial ​ $ 508,499 ​ $ 501,042 Commercial real estate - owner occupied ​ 974,085 ​ 969,413 Commercial real estate - non-owner occupied ​ 460,167 ​ 459,516 Multi-family ​ ​ 355,324 ​ ​ 326,573 Construction and development ​ 278,919 ​ 278,639 Residential 1‑4 family ​ 903,008 ​ 912,985 Consumer ​ 54,547 ​ 55,164 Other ​ 15,043 ​ 15,593 Subtotals ​ 3,549,592 ​ 3,518,925 ACL - Loans ​ ( 43,749 ) ​ ( 44,151 ) Loans, net of ACL - Loans ​ 3,505,843 ​ 3,474,774 Deferred loan fees, net ​ ( 1,522 ) ​ ( 1,757 ) Loans, net ​ $ 3,504,321 ​ $ 3,473,017 ​ The ACL - Loans is based on the Company’s evaluation of historical default and loss experience, current and projected economic conditions, asset quality trends, known and inherent risks in the portfolio, adverse situations that may affect the borrowers’ ability to repay a loan, the estimated value of any underlying collateral, composition of the loan portfolio and other relevant factors. More information regarding the Company’s methodology related to the ACL-Loans can be found in the Company’s Annual Report. ​ The Company utilized the high-end range of the Federal Reserve Bank Open Market Committee forecast for national unemployment and the low-end range for national GDP growth at March 31, 2025 and December 31, 2024. As of March 31, 2025, the Company anticipates the national unemployment rate to rise during the forecast period and the national GDP growth rate to decline. The Company utilized long-term averages for the remaining loss drivers. ​ 13 Table of Contents ​ A roll forward of the ACL-Loans is summarized as follows: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Three Months Ended ​ Year Ended ​ ​ March 31, 2025 ​ March 31, 2024 ​ December 31, 2024 ​ Beginning Balance $ 44,151 ​ $ 43,609 ​ $ 43,609 ​ Provision for credit losses ​ 400 ​ ​ 200 ​ ​ 100 ​ Charge-offs ​ ( 836 ) ​ ​ ( 52 ) ​ ​ ( 566 ) ​ Recoveries ​ 34 ​ ​ 621 ​ ​ 1,008 ​ Net (charge-offs) recoveries ​ ( 802 ) ​ ​ 569 ​ ​ 442 ​ Ending Balance $ 43,749 ​ $ 44,378 ​ $ 44,151 ​ ​ ​ A summary of the activity in the ACL - Loans by loan type for the three months ended March 31, 2025 is summarized as follows: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Commercial Commercial ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Real Estate - ​ Real Estate  - ​ ​ ​ ​ Construction ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Commercial / ​ Owner ​ Non - Owner ​ Multi- ​ and ​ Residential ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Industrial ​ Occupied ​ Occupied ​ Family ​ Development ​ 1-4 Family ​ Consumer ​ Other ​ Total ACL - Loans - January 1, 2025 ​ $ 5,394 ​ $ 11,033 ​ $ 4,740 ​ $ 3,739 ​ $ 5,223 ​ $ 12,801 ​ $ 1,084 ​ $ 137 ​ $ 44,151 Charge-offs ​ — ​ ​ ( 802 ) ​ ​ — ​ ​ — ​ — ​ ( 1 ) ​ ( 21 ) ​ ( 12 ) ​ ( 836 ) Recoveries ​ — ​ ​ — ​ ​ — ​ ​ — ​ — ​ 30 ​ — ​ 4 ​ 34 Provision ​ ( 155 ) ​ ​ 190 ​ ​ ( 9 ) ​ ​ 435 ​ 96 ​ ( 172 ) ​ 10 ​ 5 ​ 400 ACL - Loans - March 31, 2025 ​ $ 5,239 ​ $ 10,421 ​ $ 4,731 ​ $ 4,174 ​ $ 5,319 ​ $ 12,658 ​ $ 1,073 ​ $ 134 ​ $ 43,749 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ A summary of the activity in the ACL – Loans by loan type for the three months ended March 31, 2024 is summarized as follows: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Commercial Commercial ​ ​ ​ ​ ​ Real Estate - ​ Real Estate - ​ ​ ​ ​ Construction ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Commercial / ​ Owner ​ Non - Owner ​ Multi- ​ and ​ Residential ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Industrial ​ Occupied ​ Occupied ​ Family ​ Development ​ 1-4 Family ​ Consumer ​ Other ​ Total ACL - Loans - January 1, 2024 ​ $ 5,965 ​ $ 12,285 ​ $ 5,700 ​ $ 4,754 ​ $ 3,597 ​ $ 10,620 ​ $ 615 ​ $ 73 ​ $ 43,609 Charge-offs ​ ( 17 ) ​ ​ ( 1 ) ​ ​ — ​ ​ — ​ — ​ ( 1 ) ​ ( 4 ) ​ ( 29 ) ​ ( 52 ) Recoveries ​ 2 ​ ​ 611 ​ ​ — ​ ​ — ​ — ​ 3 ​ — ​ 5 ​ 621 Provision ​ ( 139 ) ​ ​ 547 ​ ​ 381 ​ ​ ( 153 ) ​ ( 359 ) ​ ( 122 ) ​ ( 7 ) ​ 52 ​ 200 ACL - Loans - March 31, 2024 ​ $ 5,811 ​ $ 13,442 ​ $ 6,081 ​ $ 4,601 ​ $ 3,238 ​ $ 10,500 ​ $ 604 ​ $ 101 ​ $ 44,378 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ In addition to the ACL-Loans, the Company has established an allowance for credit losses on unfunded commitments (“ACL-Unfunded Commitments”), classified in other liabilities on the consolidated balance sheets. This allowance is maintained to absorb losses arising from unfunded loan commitments, and is determined quarterly based on methodology similar to the methodology for determining the ACL-Loans. The ACL - Unfunded Commitments was $ 2.9 million at March 31, 2025 and December 31, 2024, respectively. See Note 10 for further information on commitments. ​ The provision for credit losses is determined by the Company as the amount to be added to the ACL accounts for various types of financial instruments including loans, investment securities, and off-balance sheet credit exposures after net charge-offs have been deducted to bring the ACL to a level that, in management’s judgment, is necessary to absorb expected credit losses over the lives of the respective financial instruments.

For collateral dependent loans, expected credit losses are based on amortized cost of the loan less the estimated fair value of the collateral at the balance sheet date, with consideration for estimated selling costs if satisfaction of the loan depends on the sale of the collateral. ​ ​ 15 Table of Contents ​ The following tables present collateral dependent loans by portfolio segment and collateral type, including those loans with and without a related allowance allocation. A significant portion of the loan balances in these tables and essentially all of the allowance allocations relate to PCD loans which were acquired from Hometown. Real estate collateral primarily consists of operating facilities of the underlying borrowers. Other business assets collateral primarily consists of equipment, receivables and inventory of the underlying borrowers. ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Collateral Type ​ ​ ​ ​ ​ ​ ​ ​ ​ As of March 31, 2025 ​ ​ ​ ​ Other ​ ​ ​ ​ Without an ​ With an ​ Allowance ​ ​ Real Estate ​ Business Assets ​ Total ​ Allowance ​ Allowance ​ Allocation Commercial/industrial ​ $ — ​ $ 789 ​ $ 789 ​ $ — ​ $ 789 ​ $ 789 Commercial real estate - owner occupied ​ 6,865 ​ — ​ 6,865 ​ 4,302 ​ 2,563 ​ 959 Commercial real estate - non-owner occupied ​ — ​ — ​ — ​ — ​ — ​ — Multi-family ​ ​ — ​ ​ — ​ ​ — ​ ​ — ​ ​ — ​ ​ — Construction and development ​ — ​ — ​ — ​ — ​ — ​ — Residential 1‑4 family ​ — ​ — ​ — ​ — ​ — ​ — Consumer ​ — ​ — ​ — ​ — ​ — ​ — Other ​ — ​ — ​ — ​ — ​ — ​ — Total Loans ​ $ 6,865 ​ $ 789 ​ $ 7,654 ​ $ 4,302 ​ $ 3,352 ​ $ 1,748 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Collateral Type ​ ​ ​ ​ ​ ​ ​ ​ ​ As of December 31, 2024 ​ ​ ​ ​ Other ​ ​ ​ ​ Without an ​ With an ​ Allowance ​ ​ Real Estate ​ Business Assets ​ Total ​ Allowance ​ Allowance ​ Allocation Commercial/industrial ​ $ — ​ $ 793 ​ $ 793 ​ $ — ​ $ 793 ​ $ 793 Commercial real estate - owner occupied ​ 7,795 ​ — ​ 7,795 ​ 800 ​ 6,995 ​ 1,601 Commercial real estate - non-owner occupied ​ — ​ — ​ — ​ — ​ — ​ — Multi-family ​ ​ — ​ ​ — ​ ​ — ​ ​ — ​ ​ — ​ ​ — Construction and development ​ — ​ — ​ — ​ — ​ — ​ — Residential 1‑4 family ​ — ​ — ​ — ​ — ​ — ​ — Consumer ​ — ​ — ​ — ​ — ​ — ​ — Other ​ — ​ — ​ — ​ — ​ — ​ — Total Loans ​ $ 7,795 ​ $ 793 ​ $ 8,588 ​ $ 800 ​ $ 7,788 ​ $ 2,394 ​ The Company utilizes a numerical risk rating system for commercial relationships. All other types of relationships (ex: residential, consumer, other) are assigned a “Pass” rating, unless they have fallen 90 days past due or more, at which time they are assessed for a rating of 5, 6 or 7. The Company uses split ratings for government guaranties on loans. The portion of a loan that is supported by a government guaranty is included with other Pass credits. The determination of a commercial loan risk rating begins with completion of a matrix, which assigns scores based on the strength of the borrower’s debt service coverage, collateral coverage, balance sheet leverage, industry outlook, and customer concentration. A weighted average is taken of these individual scores to arrive at the overall rating. This rating is subject to adjustment by the loan officer based on facts and circumstances pertaining to the borrower. Risk ratings are subject to independent review. Commercial borrowers with ratings between 1 and 5 are considered Pass credits, with 1 being most acceptable and 5 being just above the minimum level of acceptance. Commercial borrowers rated 6 have potential weaknesses which may jeopardize repayment ability. Borrowers rated 7 have a well-defined weakness or weaknesses such as the inability to demonstrate significant cash flow for debt service based on analysis of the company’s financial information. These loans remain on accrual status provided full collection of principal and interest is reasonably expected. Otherwise they are deemed impaired and placed on nonaccrual status. Borrowers rated 8 are the same as 7 rated credits with one exception: collection or liquidation in full is not probable. 16 Table of Contents ​ The following tables present total loans by risk ratings and year of origination.

MSRs are recognized as separate assets when loans sold in the secondary market are sold with servicing retained. The Company utilizes a third-party consulting firm to assist with determining an accurate assessment of the MSRs fair value. The third-party firm collects relevant data points from numerous sources. Some of these data points relate directly to the pricing level or relative value of the mortgage servicing while other data points relate to the assumptions used to derive fair value. In addition, the valuation evaluates specific collateral types, and current and historical performance of the collateral in question. The valuation process focuses on the non-distressed secondary servicing market, common industry practices and current regulatory standards. The primary determinants of the fair value of MSRs are servicing fee percentage, ancillary income, expected loan life or prepayment speeds, discount rates, costs to service, delinquency rates, foreclosure losses and recourse obligations. The valuation data also contains interest rate shock analyses for monitoring fair value changes in differing interest rate environments. Following is an analysis of activity in the MSR asset: ​ ​ ​ ​ ​ ​ ​ ​ ​ Three Months Ended Year Ended ​ ​ March 31, 2025 ​ December 31, 2024 Fair value at beginning of period ​ $ 13,369 ​ $ 13,668 ​ ​ ​ ​ ​ ​ ​ Servicing asset additions ​ 325 ​ 1,343 Loan payments and payoffs ​ ( 425 ) ​ ( 1,735 ) Changes in valuation inputs and assumptions used in the valuation model ​ 275 ​ 93 Amount recognized through earnings ​ ​ 175 ​ ​ ( 299 ) MSR asset acquired ​ — ​ — Fair value at end of period ​ $ 13,544 ​ $ 13,369 ​ ​ ​ ​ ​ ​ ​ Unpaid principal balance of loans serviced for others ​ $ 1,173,921 ​ $ 1,172,311 Mortgage servicing rights as a percent of loans serviced for others ​ 1.15 ​ 1.14 ​ The primary economic assumptions utilized by the Company in measuring the value of MSRs were constant prepayment speeds of 8.1 and 8.2 months as of March 31, 2025 and December 31, 2024, respectively, and discount rates of 10.18 % as of each of those periods. The constant prepayment speeds are obtained from publicly available sources for each of the loan programs the Company originates under. 19 Table of Contents ​ NOTE 6 – NOTES PAYABLE The Company utilizes FHLB advances to fund liquidity.

Capital adequacy guidelines and, additionally for banks, prompt corrective action regulations involve quantitative measures of assets, liabilities, and certain off-balance sheet items calculated under regulatory accounting practices. Capital amounts and classifications are also subject to qualitative judgments by regulators. Failure to meet capital requirements can initiate regulatory action. Under regulatory guidance for non-advanced approaches institutions, the Bank and Company are required to maintain minimum amounts and ratios of common equity Tier I capital to risk-weighted assets, including an additional conservation buffer determined by banking regulators. As of March 31, 2025 and December 31, 2024, this buffer was 2.5 %. The Bank met all capital adequacy requirements to which they are subject as of March 31, 2025 and December 31, 2024.

The segment is also distinguished by the level of information provided to the chief operating decision maker, who uses such information to review the performance of various components of the business such as branches, which are then aggregated as operating performance, products and services, and customers are similar. The chief operating decision maker will then evaluate the financial performance of the Company’s business components such as by evaluating significant revenues and expenses and budget to actual results in assessing the Company’s segment and in the determination of allocating resources. The chief decision maker uses revenue streams to evaluate product pricing and significant expenses to assess performance and evaluate return on assets. The chief decision maker uses consolidated net income and return on assets to benchmark the Company against its competitors. The benchmarking analysis, coupled with monitoring of budget to actual results, are used in the assessment of performance and in establishing compensation. Loans, investments, service charges, and deposits in other banks provide the significant revenues in the banking operation. Interest expense, provisions for credit losses, data processing and payroll provide the significant expenses in the banking operation. All operations are domestic. Information reported internally for performance assessment by the chief operating decision maker is identical to that which is shown in the Consolidated Statements of Income. NOTE 10 – COMMITMENTS AND CONTINGENCIES The Company enters into commitments to originate loans whereby the interest rate on the loan is determined prior to funding (rate-lock commitments). Rate-lock commitments on mortgage loans that are intended to be sold are considered to be derivatives. Accordingly, such commitments, along with any related fees received from potential borrowers, are recorded at fair value in derivative assets or liabilities, with changes in fair value recorded in the net gain or loss on sale of mortgage loans. Fair value is based on fees currently charged to enter into similar agreements and for fixed rate commitments also considers the difference between current levels of interest rates and committed rates. The notional amount of rate-lock commitments at March 31, 2025 and December 31, 2024 was approximately $ 9.6 million and $ 8.2 million, respectively. The fair value of these rate-lock commitments are not material to these financial statements and have not been recorded. The Company is party to financial instruments with off-balance sheet risk in the normal course of business to meet the financing needs of its customers. These instruments involve, to varying degrees, elements of credit risk in excess of the amount recognized in the consolidated balance sheets. The Company’s exposure to credit loss is represented by the contractual or notional amount of these commitments. The Company follows the same credit policies in making commitments as it does for on-balance-sheet instruments. Since some of the commitments are expected to expire without being drawn upon and some of the commitments may not be drawn upon to the total extent of the commitment, the notional amount of these commitments does not necessarily represent future cash requirements. The following commitments were outstanding: ​ ​ ​ ​ ​ ​ ​ ​ ​ Notional Amount ​ March 31, 2025 ​ December 31, 2024 ​ ​ ​ ​ ​ ​ ​ Commitments to extend credit: ​ ​ Fixed ​ $ 42,147 ​ $ 46,856 Variable ​ 718,072 ​ 706,353 Credit card arrangements ​ 24,384 ​ 24,399 Letters of credit ​ 10,046 ​ 11,055 ​ ​ 22 Table of Contents ​ NOTE 11 – FAIR VALUE MEASUREMENTS Accounting guidance establishes a fair value hierarchy to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. The standard describes three levels of inputs that may be used to measure fair value. Level 1: Quoted prices (unadjusted) or identical assets or liabilities in active markets that the entity has the ability to access as of the measurement date. Level 2: Significant other observable inputs other than Level 1 prices 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. Level 3: Significant unobservable inputs that reflect a reporting entity’s own assumptions about the assumptions that market participants would use in pricing an asset or liability. ​ Information regarding the fair value of assets measured at fair value on a recurring basis is as follows: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Instruments Markets Other Significant ​ ​ Measured ​ for Identical ​ Observable ​ Unobservable ​ ​ At Fair ​ Assets ​ Inputs ​ Inputs ​ ​ Value ​ (Level 1) ​ (Level 2) ​ (Level 3) March 31, 2025 ​ ​ ​ ​ Assets ​ ​ ​ ​ Securities available for sale ​ ​ ​ ​ ​ Obligations of U.S. Government sponsored agencies ​ $ 32,364 ​ $ — ​ $ 32,364 ​ $ — Obligations of states and political subdivisions ​ 56,090 ​ — ​ 56,090 ​ — Mortgage-backed securities ​ ​ 60,784 ​ ​ — ​ ​ 60,784 ​ ​ — Corporate notes ​ 14,505 ​ — ​ 14,505 ​ — Mortgage servicing rights ​ 13,544 ​ — ​ 13,544 ​ — ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ December 31, 2024 ​ ​ ​ ​ Assets ​ ​ ​ ​ Securities available for sale ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ U.S. Treasury securities ​ $ 99,656 ​ $ 99,656 ​ $ — ​ $ — Obligations of U.S. Government sponsored agencies ​ ​ 24,741 ​ ​ — ​ ​ 24,741 ​ ​ — Obligations of states and political subdivisions ​ 56,357 ​ — ​ 56,357 ​ — Mortgage-backed securities ​ ​ 27,993 ​ ​ — ​ ​ 27,993 ​ ​ — Corporate notes ​ 14,314 ​ — ​ 14,314 ​ — Mortgage servicing rights ​ 13,369 ​ — ​ 13,369 ​ — ​ There were no assets measured on a recurring basis using significant unobservable inputs (Level 3) during these periods.

For loans individually evaluated, the amount of reserve is based upon the present value of expected future cash flows discounted at the loan’s effective interest rate, the estimated fair value of the underlying collateral for collateral-dependent loans, or the estimated liquidity of the note. For OREO, the fair value is based upon the estimated fair value of the underlying collateral adjusted for the expected costs to sell.

Fair value is best determined based upon quoted market prices. However, in many instances, there are no quoted market prices for the Company’s various financial instruments. In cases where quoted market prices are not available, fair values are based on estimates using present value or other valuation techniques. Those techniques are significantly affected by the assumptions used, including the discount rate and estimates of future cash flows. Accordingly, the fair value estimates may not be realized in an immediate settlement of the instrument. Consequently, the aggregate fair value amounts presented may not necessarily represent the underlying fair value of the Company. Fair value estimates are made at a specific 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 Company’s entire holdings of a particular instrument. Because no market exists for a significant portion of the Company’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 that could affect the estimates. Fair value estimates are based on existing on- and off-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. Deposits with no stated maturities are defined as having a fair value equivalent to the amount payable on demand. This prohibits adjusting fair value derived from retaining those deposits for an expected future period of time. This component, commonly referred to as a deposit base intangible, is neither considered in the above amounts nor is it recorded as an intangible asset on the consolidated balance sheet. Significant assets and liabilities that are not considered financial assets and liabilities include premises and equipment. 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 have not been considered in the estimates. ​ 25 Table of Contents ​ NOTE 12 – STOCK BASED COMPENSATION The Company has made restricted share grants pursuant to the Bank First Corporation 2011 Equity Plan and the Bank First Corporation 2020 Equity Plan, which replaced the 2011 Plan. The purpose of the Plan is to provide financial incentives for selected employees and for the non-employee Directors of the Company, thereby promoting the long-term growth and financial success of the Company. The number of shares of Company stock that may be issued pursuant to awards under the 2020 Plan shall not exceed, in the aggregate, 700,000 . As of March 31, 2025, 124,054 shares of Company stock have been awarded under the 2020 Plan. Compensation expense for restricted stock is based on the fair value of the awards of Bank First Corporation common stock at the time of grant. The value of restricted stock grants that are expected to vest is amortized into expense over the vesting periods. For the three months ended March 31, 2025 and 2024, compensation expense of $ 0.6 million and $ 0.6 million, respectively, was recognized related to restricted stock awards. As of March 31, 2025, there was $ 3.8 million of unrecognized compensation cost related to non-vested restricted stock awards granted under the plan. That cost is expected to be recognized over a weighted average period of 1.96 years. The aggregate grant date fair value of restricted stock awards that vested during the three months ended March 31, 2025, was approximately $ 2.1 million. ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ For the period ended ​ For the period ended ​ ​ March 31, 2025 ​ March 31, 2024 ​ ​ Weighted- ​ Weighted- ​ ​ ​ ​ Average Grant- ​ ​ ​ Average Grant- ​ ​ Shares ​ Date Fair Value ​ Shares ​ Date Fair Value Restricted Stock ​ ​ Outstanding at beginning of period 52,634 ​ $ 79.27 58,196 ​ $ 72.28 Granted 23,100 ​ 105.96 24,581 ​ 85.85 Vested ( 28,290 ) ​ 75.74 ( 30,143 ) ​ 71.14 Forfeited or cancelled — ​ — — ​ — Outstanding at end of period 47,444 ​ $ 94.37 52,634 ​ $ 79.27 ​ ​ ​ NOTE 13 – SUBSEQUENT EVENT On April 25, 2025, the Company’s Board of Directors declared a special cash dividend of $ 3.50 per share of the Company’s common stock.

MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS The following discussion and analysis of our financial condition and results of operations should be read in conjunction with our audited consolidated financial statements for the year ended December 31, 2024, included in our Annual Report and with our unaudited condensed accompanying notes set forth in this Quarterly Report on Form 10-Q for the quarterly period March 31, 2025. FORWARD-LOOKING STATEMENTS Certain statements contained in this report are forward-looking statements within the meaning of and subject to the safe harbor protections of the Private Securities Litigation Reform Act of 1995. These forward-looking statements include, without limitation, statements relating to the Company’s assets, business, cash flows, condition (financial or otherwise), credit quality, financial performance, liquidity, short and long-term performance goals, prospects, results of operations, strategic initiatives, potential future acquisitions, disposition and other growth opportunities. These statements, which are based upon certain assumptions and estimates and describe the Company’s future plans, results, strategies and expectations, can generally be identified by the use of the words and phrases “may,” “will,” “should,” “could,” “would,” “goal,” “plan,” “potential,” “estimate,” “project,” “believe,” “intend,” “anticipate,” “expect,” “target,” “aim,” “predict,” “continue,” “seek,” “projection” and other variations of such words and phrases and similar expressions. These forward-looking statements are not historical facts, and are based upon current expectations, estimates and projections about the Company’s industry, management’s beliefs and certain assumptions made by management, many of which, by their nature, are inherently uncertain and beyond the Company’s control. The inclusion of these forward-looking statements should not be regarded as a representation by the Company or any other person that such expectations, estimates and projections will be achieved. Accordingly, the Company cautions investors that any such forward-looking statements are not guarantees of future performance and are subject to risks, assumptions and uncertainties that are difficult to predict and that are beyond the Company’s control. Although the Company believes that the expectations reflected in these forward-looking statements are reasonable as of the date of this report, actual results may prove to be materially different from the results expressed or implied by the forward-looking statements. A number of factors could cause actual results to differ materially from those contemplated by the forward-looking statement in this report including, without limitation, the risks and other factors set forth in the Company’s Registration Statements under the captions “Cautionary Note Regarding Forward-Looking Statements” and “Risk factors.” Many of these factors are beyond the Company’s ability to control or predict. If one or more events related to these or other risks or uncertainties materialize, or if the Company’s underlying assumptions prove to be incorrect, actual results may differ materially from the forward-looking statements. Accordingly, investors should not place undue reliance on any such forward-looking statements. Any forward-looking statements speaks only as of the date of this report, and the Company does not undertake any obligation to publicly update or review any forward-looking statement, whether as a result of new information, future developments or otherwise, except as required by law. New risks and uncertainties may emerge from time to time, and it is not possible for the Company to predict their occurrence or how they will affect the Company. We qualify all of our forward-looking statements by these cautionary statements. OVERVIEW Bank First Corporation is a Wisconsin corporation that was organized primarily to serve as the holding company for Bank First, N.A. Bank First, N.A., which was incorporated in 1894, is a nationally-chartered bank headquartered in Manitowoc, Wisconsin. It is a member of the Board of Governors of the Federal Reserve System (“Federal Reserve”), and is regulated by the Office of the Comptroller of the Currency (“OCC”). Including its headquarters in Manitowoc, Wisconsin, the Bank has twenty-six banking locations in Manitowoc, Outagamie, Brown, Winnebago, Sheboygan, Shawano, Waupaca, Ozaukee, Monroe, Fond du Lac, Waushara, Dane, Columbia and Jefferson counties in Wisconsin. The Bank offers loan, deposit and treasury management products at each of its banking locations. 27 Table of Contents ​ As with most community banks, the Bank derives a significant portion of its income from interest received on loans and investments. The Bank’s primary source of funding is deposits, both interest-bearing and noninterest-bearing. In order to maximize the Bank’s net interest income, or the difference between the income on interest-earning assets and the expense of interest-bearing liabilities, the Bank must not only manage the volume of these balance sheet items, but also the yields earned on interest-earning assets and the rates paid on interest-bearing liabilities. To account for credit risk inherent in all loans, the Bank maintains an ACL - Loans to absorb possible losses on existing loans that may become uncollectible. The Bank establishes and maintains this allowance by charging a provision for loan losses against operating earnings. Beyond its net interest income, the Bank further receives income through the net gain on sale of loans held for sale as well as servicing income which is retained on those sold loans. In order to maintain its operations and bank locations, the Bank incurs various operating expenses which are further described within the “Results of Operations” later in this section. 28 Table of Contents ​ SELECTED HISTORICAL CONSOLIDATED FINANCIAL DATA The following tables present certain selected historical consolidated financial data as of the dates or for the period indicated: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ At or for the Three Months Ended ​ (In thousands, except per share data) 3/31/2025 12/31/2024 9/30/2024 6/30/2024 3/31/2024 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Results of Operations: ​ ​ ​ ​ ​ Interest income ​ $ 55,048 ​ $ 53,754 ​ $ 54,032 ​ $ 49,347 ​ $ 49,272 ​ Interest expense ​ 18,511 ​ 18,193 ​ 18,149 ​ 16,340 ​ 15,923 ​ Net interest income ​ 36,537 ​ 35,561 ​ 35,883 ​ 33,007 ​ 33,349 ​ Provision for credit losses ​ 400 ​ (1,000) ​ — ​ — ​ 200 ​ Net interest income after provision for credit losses ​ 36,137 ​ 36,561 ​ 35,883 ​ 33,007 ​ 33,149 ​ Noninterest income ​ 6,588 ​ 4,513 ​ 4,893 ​ 5,877 ​ 4,397 ​ Noninterest expense ​ 20,604 ​ 19,286 ​ 20,100 ​ 19,057 ​ 20,324 ​ Income before income tax expense ​ 22,121 ​ 21,788 ​ 20,676 ​ 19,827 ​ 17,222 ​ Income tax expense ​ 3,880 ​ 4,248 ​ 4,124 ​ 3,768 ​ 1,810 ​ Net income ​ $ 18,241 ​ $ 17,540 ​ $ 16,552 ​ $ 16,059 ​ $ 15,412 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Earnings per common share -

(2) Income statement-related ratios for partial year periods are annualized. GAAP RECONCILIATION AND MANAGEMENT EXPLANATION OF NON-GAAP FINANCIAL MEASURES We identify certain financial measures discussed in the Report as being “non-GAAP financial measures.” The non-GAAP financial measures presented in this Report are tangible book value per common share and tangible equity to tangible assets. In accordance with the SEC’s rules, we classify a financial measure as being a non-GAAP financial measure if that financial measure excludes or includes amounts, or is subject to adjustments that have the effect of excluding or including amounts, that are included or excluded, as the case may be, in the most directly comparable measure calculated and presented in accordance with GAAP as in effect from time to time in the United States in our statements of income, balance sheets or statements of cash flows. The non-GAAP financial measures that we discuss in this Report should not be considered in isolation or as a substitute for the most directly comparable or other financial measures calculated in accordance with GAAP. Moreover, the manner in which we calculate the non-GAAP financial measures that we discuss in our selected historical consolidated financial data may differ from that of other companies reporting measures with similar names. You should understand how such other banking organizations calculate their financial measures similar or with names similar to the non-GAAP financial measures we have presented in our selected historical consolidated financial data when comparing such non-GAAP financial measures. The following discussion and reconciliations provide a more detailed analysis of these non-GAAP financial measures. 30 Table of Contents ​ Tangible book value per common share and tangible equity to tangible assets are non-GAAP measures that exclude the impact of goodwill and other intangibles used by the Company’s management to evaluate capital adequacy. Because intangible assets such as goodwill and other intangibles vary extensively from company to company, we believe that the presentation of this information allows investors to more easily compare the Company’s capital position to other companies. The most directly comparable financial measures calculated in accordance with GAAP are book value per common share, return on average common equity and stockholders’ equity to total assets. ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ At or for the Three Months Ended ​ (In thousands, except per share data) 3/31/2025 12/31/2024 9/30/2024 6/30/2024 3/31/2024 Tangible Assets ​ ​ ​ ​ ​ ​ ​ Total assets ​ $ 4,505,065 ​ $ 4,495,060 ​ $ 4,294,498 ​ $ 4,145,820 ​ $ 4,099,924 ​ Adjustments: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Goodwill ​ (175,106) ​ (175,106) ​ (175,106) ​ (175,106) ​ (175,106) ​ Core deposit intangible, net of amortization ​ (19,905) ​ (21,203) ​ (22,592) ​ (24,021) ​ (25,496) ​ Tangible assets ​ $ 4,310,054 ​ $ 4,298,751 ​ $ 4,096,800 ​ $ 3,946,693 ​ $ 3,899,322 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Tangible Common Equity ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Total stockholders’ equity ​ $ 648,414 ​ $ 639,683 ​ $ 628,895 ​ $ 614,579 ​ $ 609,330 ​ Adjustments: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Goodwill ​ (175,106) ​ (175,106) ​ (175,106) ​ (175,106) ​ (175,106) ​ Core deposit intangible, net of amortization ​ (19,905) ​ (21,203) ​ (22,592) ​ (24,021) ​ (25,496) ​ Tangible common equity ​ $ 453,403 ​ $ 443,374 ​ $ 431,197 ​ $ 415,452 ​ $ 408,728 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Book value per common share ​ $ 65.02 ​ $ 63.89 ​ $ 62.82 ​ $ 61.27 ​ $ 60.16 ​ Tangible book value per common share ​ 45.46 ​ 44.28 ​ 43.07 ​ 41.42 ​ 40.35 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Total stockholders’ equity to total assets ​ 14.39 % 14.23 % 14.64 % 14.82 % 14.86 % Tangible common equity to tangible assets ​ 10.52 % 10.31 % 10.53 % 10.53 % 10.48 % ​ RESULTS OF OPERATIONS Results of Operations for the Three Months Ended March 31, 2025 and March 31, 2024 General . Net income increased $2.8 million to $18.2 million for three months ended March 31, 2025, compared to $15.4 million for the same period in 2024. This increase is primarily driven by the repricing of new and renewed loans in a higher rate environment, along with steady growth in interest-bearing assets. Net Interest Income . The management of interest income and expense is fundamental to our financial performance. Net interest income, the difference between interest income and interest expense, is the largest component of the Company’s total revenue. Management closely monitors both total net interest income and the net interest margin (net interest income divided by average earning assets). We seek to maximize net interest income without exposing the Company to an excessive level of interest rate risk through our asset and liability policies. Interest rate risk is managed by monitoring the pricing, maturity and repricing options of all classes of interest-bearing assets and liabilities. Our net interest margin can also be adversely impacted by the reversal of interest on nonaccrual loans and the reinvestment of loan payoffs into lower yielding investment securities and other short-term investments. Net interest and dividend income increased by $3.2 million to $36.5 million for the three months ended March 31, 2025 compared to $33.3 million for three months ended March 31, 2024. The increase in net interest income was primarily due to repricing of new and renewed loans in a higher interest rate environment, as well as steady growth in interest-bearing assets. Total average interest-earning assets were $4.10 billion for the three months ended March 31, 2025, up from $3.74 billion for the same period in 2024. Net interest margin and net interest income are influenced by internal and external factors. Internal factors include balance sheet changes on both volume and mix and pricing decisions, and external factors include changes in market interest rates, competition and the shape of the interest rate yield curve. Interest Income. Total interest income increased $5.7 million, or 11.7%, to $55.0 million for the three months ended March 31, 2025 compared to $49.3 million for the same period in 2024. The increase in total interest income was primarily due to an increase in in interest-earning assets coupled with higher average interest rates earned on interest-earning assets. The average balance of interest-earning assets increased by $359.3 million during the three months ended March 31, 2025 compared to the same period in 2024 and the average interest rate earned on these assets increased by 0.16% in the year-over-year first quarters. 31 Table of Contents ​ Interest Expense. Interest expense increased $2.6 million, or 16.3%, to $18.5 million for the three months ended March 31, 2025 compared to $15.9 million for the same period in 2024. The increase in interest expense was primarily due to higher crediting interest rates on also higher levels of interest-bearing liabilities. Interest expense on interest-bearing deposits increased by $1.5 million to $16.9 million for the three months ended March 31, 2025 compared to $15.4 million for the same period in 2024. The average balance and rate of interest-bearing deposits was $2.69 billion and 2.54% for the three months ended March 31, 2025, compared to $2.46 billion and 2.51% for the same period in 2024. The Bank's cost of funds decreased by 0.08% from the fourth quarter of 2024, including a decrease of 0.18% in the average rate paid on the Bank's non-brokered certificates of deposit. Provision for Credit Losses. Credit risk is inherent in the business of making loans. We establish an allowance for credit losses through charges to earnings, which are shown in the statements of operations as the provision for credit losses. The provision for credit losses and level of allowance for each period are dependent upon many factors, including loan growth, net charge-offs, changes in the composition of the loan portfolio, delinquencies, management’s assessment of the quality of the loan portfolio, the valuation of problem loans and the general economic conditions in our market area. The determination of the amount is complex and involves a high degree of judgment and subjectivity. We recorded a provision of $0.4 million for credit loss during the three months ended March 31, 2025 compared to a provision of $0.2 million for credit loss during the same period in 2024. Economic forecasts, primarily US gross domestic product projections, decreased slightly during the first quarter of 2025 while projections for unemployment increased. We recorded net charge offs of $0.8 million during the three months ended March 31, 2025 compared to net recoveries of $0.6 million during the three months ended March 31, 2024. Other than a $0.8 million charge-off during the first quarter of 2025, related to a single customer relationship, the Bank’s loan portfolio continues to exhibit very little credit stress. The ACL - Loans was $43.7 million, or 1.23% of total loans, at March 31, 2025 compared to $44.4 million, or 1.31% of total loans at March 31, 2024. Noninterest Income. Noninterest income is an important component of our total revenues. A significant portion of our noninterest income has historically been associated with service charges and income from the Bank’s unconsolidated subsidiary, Ansay. Other sources of noninterest income include loan servicing fees and gains on sales of mortgage loans. Noninterest income increased $2.2 million to $6.6 million for the three months ended March 31, 2025 compared to $4.4 million for the same period in 2024. Service charges increased by 23.0% from the prior-year first quarter as the Bank continues to benefit from a renegotiated vendor incentive program related to credit and debit card payments processing. Positive valuation adjustments to the Bank’s MSRs totaling $0.2 million during the first quarter of 2025 compared favorably to $0.3 million in negative valuation adjustments during the first quarter of 2024. Finally, the Bank received a $2.3 million death benefit related to its bank-owned life insurance portfolio. The underlying policies had a cash value of $1.3 million, leading to a gain of $1.0 million which is recorded in other noninterest income. The major components of our noninterest income are listed below: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Three Months Ended March 31, ​ ​ 2025 2024 $ Change % Change (in thousands) ​ (In thousands) ​ Noninterest Income ​ ​ ​ ​ ​ Service charges ​ $ 2,011 ​ $ 1,634 ​ $ 377 ​ ​ 23 % ​ Income from Ansay ​ ​ 1,181 ​ ​ 979 ​ ​ 202 ​ ​ 21 % ​ Loan servicing income ​ 732 ​ 726 ​ 6 ​ 1 % ​ Valuation adjustment on MSR ​ ​ 175 ​ ​ (312) ​ ​ 487 ​ ​ NM % ​ Net gain on sales of mortgage loans ​ 334 ​ 219 ​ 115 ​ 53 % ​ Other ​ 2,155 ​ 1,151 ​ 1,004 ​ 87 % ​ Total noninterest income ​ $ 6,588 ​ $ 4,397 ​ $ 2,191 ​ ​ 50 % ​ ​ 32 Table of Contents ​ Noninterest Expense. Noninterest expense increased $0.3 million to $20.6 million for the three months ended March 31, 2025 compared to $20.3 million for the same period in 2024. Most noninterest expenses have remained well-controlled over the past five quarters. Due to the gain on bank-owned life insurance noted earlier, the Bank accelerated some charitable giving which had been planned for later in the year into the first quarter. Also, federal deposit insurance increased primarily due to elevated deposit levels which were developed late in the fourth quarter of 2024 and persisted through the first quarter of 2025.

We recorded a provision for income taxes of $3.9 million for the three months ended March 31, 2025 compared to a provision of $1.8 million for the same period during 2024, reflecting effective tax rates of 17.5% and 10.5%, respectively. The Company’s home state passed tax legislation during the third quarter of 2023 which exempted income from a significant portion of the Company’s loans from taxation in Wisconsin. As a result of this legislation, income from a significant portion of the Company’s loans will no longer be subject to taxation in its home state. Final rules relating to qualifying loans under this legislation were not published until the first quarter of 2024. Based on these final rules, the Company was able to further reduce its estimated tax liability from 2023 by $1.3 million, resulting in the lower provision for income taxes and effective tax rate during the first quarter of 2024. Although not as impactful as this event in the first quarter of 2024, tax-exempt income during the first quarter of 2025 resulting from a death benefit on life insurance lowered the effective tax rate for the most recent quarter from levels seen in the final three quarters of 2024. 33 Table of Contents ​ NET INTEREST MARGIN Net interest income represents the difference between interest earned, primarily on loans and investments, and interest paid on funding sources, primarily deposits and borrowings. Interest rate spread is the difference between the average rate earned on total interest-earning assets and the average rate paid on total interest-bearing liabilities. Net interest margin is the amount of net interest income, on a fully taxable-equivalent basis, expressed as a percentage of average interest-earning assets. The average rate earned on earning assets is the amount of annualized taxable-equivalent interest income expressed as a percentage of average earning assets. The average rate paid on interest-bearing liabilities is equal to annualized interest expense as a percentage of average interest-bearing liabilities.

Total assets increased $11.4 million, or 0.3%, to $4.51 billion at March 31, 2025, from $4.50 billion at December 31, 2024. Cash and Cash Equivalents. Cash and cash equivalents increased by $39.5 million to $300.9 million at March 31, 2025, from $261.3 million at December 31, 2024. Investment Securities. The carrying value of total investment securities decreased by $59.8 million to $274.0 million at March 31, 2025, from $333.8 million at December 31, 2024. The quarter-over-quarter decrease in investments was primarily attributed to the maturity of short-duration securities during the most recent quarter. These investments were acquired during the fourth quarter of 2024 to meet heightened needs for collateral due to a seasonal collateralized deposit increase during the fourth quarter of 2024. Loans. Net loans increased by $31.3 million, totaling $3.50 billion at March 31, 2025 compared to $3.47 billion at December 31, 2024. 35 Table of Contents ​ Deposits. Deposits increased $13.1 million, or 0.4%, to $3.67 billion at March 31, 2025 from $3.66 billion at December 31, 2024. Borrowings. At March 31, 2025, borrowings consisted of advances from the FHLB of Chicago and subordinated debt to other banks and an individual. FHLB borrowings decreased $0.5 million, or 0.4%, to $134.9 million at March 31, 2025 from $135.4 million at December 31, 2024. Subordinated debt remained stable at $12.0 million at March 31, 2025 and December 31, 2024. Stockholders’ Equity. Total stockholders’ equity increased $8.7 million, or 1.4%, to $648.4 million at March 31, 2025 from $639.7 million at December 31, 2024. Repurchases of the Company’s common stock totaling $6.4 million and dividends declared totaling $4.5 million offset the positive impact of earnings totaling $18.2 million during the first three months of the year. LOANS Our lending activities are principally conducted in the state of Wisconsin. The Bank makes commercial and industrial loans, commercial real estate loans, construction and development loans, residential real estate loans, and a variety of consumer loans and other loans. Much of the loans made by the Bank are secured by real estate collateral. The Bank’s commercial business loans are primarily made based on the cash flow of the borrower and secondarily on the underlying collateral provided by the borrower, with liquidation of the underlying real estate collateral typically being viewed as the primary source of repayment in the event of borrower default. Although commercial business loans are also often collateralized by equipment, inventory, accounts receivable, or other business assets, the liquidation of collateral in the event of default is often an insufficient source of repayment. Repayment of the Bank’s residential loans are generally dependent on the health of the employment market in the borrowers’ geographic areas and that of the general economy with liquidation of the underlying real estate collateral being typically viewed as the primary source of repayment in the event of borrower default. Our loan portfolio is our most significant earning asset, comprising 78.8% and 78.3% of our total assets as of March 31, 2025 and December 31, 2024, respectively. Our strategy is to grow our loan portfolio by originating quality commercial and consumer loans that comply with our credit policies and that produce revenues consistent with our financial objectives. We believe our loan portfolio is well-balanced, which provides us with the opportunity to grow while monitoring our loan concentrations. Loans increased $30.9 million, or 0.9%, to $3.55 billion as of March 31, 2025 compared to $3.52 billion as of December 31, 2024. This increase during the first three months of 2025 was primarily driven by solid demand for new credit from our existing customer relationships. This growth was comprised of an increase of $7.5 million or 1.5% in commercial and industrial loans, an increase of $4.8 million or 0.5% in owner occupied commercial real estate loans, an increase of $0.6 million or 0.1% in non-owner occupied commercial real estate, an increase of $28.6 million or 8.8% in multi-family loans, an increase of $0.5 million or 0.2% in construction and development loans, a decrease of $9.9 million or 1.1% in residential 1-4 family loans and a decrease of $1.2 million or 1.7% in consumer and other loans. The following table presents the balance and associated percentage of each major category in our loan portfolio: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ March 31, 2025 ​ December 31, 2024 ​ March 31, 2024 ​ Amount % of Total Amount % of Total Amount % of Total ​ (dollars in thousands) ​ Commercial & industrial $ 507,850 ​ 14 % $ 500,352 14 % $ 510,396 15 % Commercial real estate ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Owner occupied ​ 973,578 ​ 27 % 968,837 28 % 892,275 ​ 26 % Non-owner occupied ​ 460,077 ​ 13 % 459,431 13 % 502,429 ​ 15 % Multi-family ​ 355,003 ​ 10 % 326,408 9 % 323,047 ​ 10 % Construction & development ​ 278,475 ​ 8 % 277,971 8 % 207,866 ​ 6 % Residential 1-4 family ​ 903,280 ​ 26 % 913,187 26 % 880,241 ​ 26 % Consumer ​ 54,763 ​ 2 % 55,387 2 % 52,296 ​ 2 % Other loans ​ 15,044 ​ — % 15,595 — % 14,845 ​ — % Total Loans ​ $ 3,548,070 ​ 100 % $ 3,517,168 100 % $ 3,383,395 ​ 100 % ​ 36 Table of Contents ​ Loan categories The principal categories of our loan portfolio are discussed below: Commercial and Industrial (C&I). Our C&I portfolio totaled $507.9 million and $500.4 million at March 31, 2025 and December 31, 2024, respectively, and represented 14% of our total loans at both dates. Our C&I loan customers represent various small and middle-market established businesses involved in professional services, accommodation and food services, health care, financial services, wholesale trade, manufacturing, distribution, retailing and non-profits. Most clients are privately owned with markets that range from local to national in scope. Many of the loans to this segment are secured by liens on corporate assets and the personal guarantees of the principals. The regional economic strength or weakness impacts the relative risks in this loan category. There is little concentration in any one business sector, and loan risks are generally diversified among many borrowers. We actively communicate with our C&I loan customers regarding their operations, including the impacts of recently implemented tariffs on their input costs and customer relationships. We have not noted significant pressure on our customer base from the current uncertain economic environment, but we will continue to monitor the impact of these items on our loan portfolio and its credit quality. Commercial Real Estate (CRE). Our CRE loan portfolio totaled $1.79 billion and $1.75 billion at March 31, 2025 and December 31, 2024, respectively, and represented 50% of our total loans at those dates. The growth in our CRE loan portfolio through the first three months of 2025 consisted primarily of multi-family real estate as developers respond to a shortage of available dwellings in our markets. Management views owner occupied CRE, which expanded marginally during the quarter, as an extension of C&I lending as typically the primary repayment source on these loans is operating profits from the underlying business. Our CRE loans are secured by a variety of property types including multi-family dwellings, retail facilities, office buildings, commercial mixed use, lodging and industrial and warehouse properties. We do not have any specific industry or customer concentrations in our CRE portfolio. Our commercial real estate loans are generally for terms up to ten years, with loan-to-values that generally do not exceed 80%. Amortization schedules are long term and thus a balloon payment is generally due at maturity. Under most circumstances, the Bank will offer to rewrite or otherwise extend the loan at prevailing interest rates. Construction and Development (C&D). Our C&D loan portfolio totaled $278.5 million and $278.0 million at March 31, 2025 and December 31, 2024, respectively, and represented 8% of our total loans at those dates. Our C&D loans are generally for the purpose of creating value out of real estate through construction and development work, and also include loans used to purchase recreational use land. Borrowers typically provide a copy of a construction or development contract which is subject to bank acceptance prior to loan approval. Disbursements are handled by a title company. Borrowers are required to inject their own equity into the project prior to any note proceeds being disbursed. These loans are, by their nature, intended to be short term and are refinanced into other loan types at the end of the construction and development period. Residential 1 – 4 Family. Residential 1 – 4 family loans held in portfolio amounted to $903.3 million and $913.2 million at March 31, 2025 and December 31, 2024, respectively, and represented 26% of our total loans at those dates. We offer fixed and adjustable-rate residential mortgage loans with maturities up to 30 years. One-to-four family residential mortgage loans are generally underwritten according to Fannie Mae guidelines, and we refer to loans that conform to such guidelines as “conforming loans.” We generally originate both fixed and adjustable-rate mortgage loans in amounts up to the maximum conforming loan limits as established by the Federal Housing Finance Agency, which is generally $726,200 for one-unit properties. In addition, we also offer loans above conforming lending limits typically referred to as “jumbo” loans. These loans are typically underwritten to the same guidelines as conforming loans; however, we may choose to hold a jumbo loan within its portfolio with underwriting criteria that does not exactly match conforming guidelines. 37 Table of Contents ​ We do not offer reverse mortgages nor do we offer loans that provide for negative amortization of principal, such as “Option ARM” loans, where the borrower can pay less than the interest owed on his loan, resulting in an increased principal balance during the life of the loan. We also do not offer “subprime loans” (loans that are made with low down payments to borrowers with weakened credit histories typically characterized by payment delinquencies, previous charge-offs, judgments, bankruptcies, or borrowers with questionable repayment capacity as evidenced by low credit scores or high debt-burden ratios) or Alt-A loans (defined as loans having less than full documentation). Residential real estate loans are originated both for sale to the secondary market as well as for retention in the Bank’s loan portfolio. The decision to sell a loan to the secondary market or retain within the portfolio is determined based on a variety of factors including but not limited to our asset/liability position, the current interest rate environment, and customer preference. Servicing rights are retained on all loans sold to the secondary market. We were servicing mortgage loans sold to others without recourse of approximately $1.17 billion at March 31, 2025 and December 31, 2024. Loans sold with the retention of servicing assets result in the capitalization of servicing rights. Loan servicing rights are carried at fair value. The net balance of capitalized servicing rights amounted to $13.5 million and $13.4 million at March 31, 2025 and December 31, 2024, respectively. Consumer Loans. Our consumer loan portfolio totaled $54.8 million and $55.4 million at March 31, 2025 and December 31, 2024, respectively, and represented 2% of our total loans at those dates. Consumer loans include secured and unsecured loans, lines of credit and personal installment loans. Consumer loans generally have greater risk compared to longer-term loans secured by improved, owner-occupied real estate, particularly consumer loans that are secured by rapidly depreciable assets. In these cases, any repossessed collateral for a defaulted loan may not provide an adequate source of repayment of the outstanding loan balance. As a result, consumer loan repayments are dependent on the borrower’s continuing financial stability and thus are more likely to be adversely affected by job loss, divorce, illness or personal bankruptcy. Other Loans. Our other loans totaled $15.0 million and $15.6 million at March 31, 2025 and December 31, 2024, respectively, and are immaterial to the overall loan portfolio. The other loans category consists primarily of over-drafted depository accounts, loans utilized to purchase or carry securities and loans to nonprofit organizations. 38 Table of Contents ​ Loan Portfolio Maturities. The following tables summarize the dollar amount of loans maturing in our portfolio based on their loan type, fixed or variable rate of interest, and contractual terms to maturity at March 31, 2025. The tables do not include any estimate of prepayments, which can significantly shorten the average life of all loans and may cause our actual repayment experience to differ from that shown below. Demand loans, loans having no stated repayment schedule or maturity, and overdraft loans are reported as being due in one year or less. ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ One Year or ​ One to Five ​ Five to Fifteen ​ Over Fifteen ​ ​ ​ ​ ​ Less ​ Years ​ Years ​ Years ​ Total ​ ​ (dollars in thousands) Commercial & industrial $ 157,712 $ 237,205 $ 111,143 ​ $ 1,790 $ 507,850 Commercial real estate ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Owner Occupied ​ ​ 143,301 ​ ​ 450,156 ​ ​ 310,776 ​ ​ 69,345 ​ ​ 973,578 Non-owner Occupied ​ ​ 53,047 ​ ​ 293,218 ​ ​ 113,487 ​ ​ 325 ​ ​ 460,077 Multi-family ​ ​ 29,715 ​ ​ 135,702 ​ ​ 189,093 ​ ​ 493 ​ ​ 355,003 Construction & Development ​ ​ 45,346 ​ ​ 102,709 ​ ​ 55,006 ​ ​ 75,414 ​ ​ 278,475 Residential 1-4 family ​ ​ 22,994 ​ ​ 96,731 ​ ​ 206,214 ​ ​ 577,341 ​ ​ 903,280 Consumer and other ​ ​ 15,125 ​ ​ 32,123 ​ ​ 15,846 ​ ​ 6,713 ​ ​ 69,807 Total ​ $ 467,240 ​ $ 1,347,844 ​ $ 1,001,565 ​ $ 731,421 ​ $ 3,548,070 Fixed Rate Loans: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Commercial & industrial ​ $ 41,040 ​ $ 173,910 ​ $ 59,974 ​ $ 1,757 ​ $ 276,681 Commercial real estate ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Owner Occupied ​ ​ 74,275 ​ ​ 349,445 ​ ​ 104,958 ​ ​ 20,244 ​ ​ 548,922 Non-owner Occupied ​ ​ 46,043 ​ ​ 255,635 ​ ​ 28,158 ​ ​ — ​ ​ 329,836 Multi-family ​ ​ 26,948 ​ ​ 126,648 ​ ​ 123,160 ​ ​ — ​ ​ 276,756 Construction & Development ​ ​ 27,994 ​ ​ 85,327 ​ ​ 10,296 ​ ​ 40,913 ​ ​ 164,530 Residential 1-4 family ​ ​ 14,039 ​ ​ 77,031 ​ ​ 158,693 ​ ​ 276,137 ​ ​ 525,900 Consumer and other ​ ​ 14,425 ​ ​ 30,909 ​ ​ 14,810 ​ ​ 6,713 ​ ​ 66,857 Total ​ $ 244,764 ​ $ 1,098,905 ​ $ 500,049 ​ $ 345,764 ​ $ 2,189,482 Floating Rate Loans: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Commercial & industrial ​ $ 116,672 ​ $ 63,295 ​ $ 51,169 ​ $ 33 ​ $ 231,169 Commercial real estate ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Owner Occupied ​ ​ 69,026 ​ ​ 100,711 ​ ​ 205,818 ​ ​ 49,101 ​ ​ 424,656 Non-owner Occupied ​ ​ 7,004 ​ ​ 37,583 ​ ​ 85,329 ​ ​ 325 ​ ​ 130,241 Multi-family ​ ​ 2,767 ​ ​ 9,054 ​ ​ 65,933 ​ ​ 493 ​ ​ 78,247 Construction & Development ​ ​ 17,352 ​ ​ 17,382 ​ ​ 44,710 ​ ​ 34,501 ​ ​ 113,945 Residential 1-4 family ​ ​ 8,955 ​ ​ 19,700 ​ ​ 47,521 ​ ​ 301,204 ​ ​ 377,380 Consumer and other ​ ​ 700 ​ ​ 1,214 ​ ​ 1,036 ​ ​ — ​ ​ 2,950 Total ​ $ 222,476 ​ $ 248,939 ​ $ 501,516 ​ $ 385,657 ​ $ 1,358,588 ​ NONPERFORMING ASSETS In order to operate with a sound risk profile, we focus on originating loans that we believe to be of high quality. We have established loan approval policies and procedures to assist us in maintaining the overall quality of our loan portfolio. When delinquencies in our loans exist, we rigorously monitor the levels of such delinquencies for any negative or adverse trends. From time to time, we may modify loans to extend the term or make other concessions to help a borrower with a deteriorating financial condition stay current on their loan and to avoid foreclosure. We generally do not forgive principal or interest on loans or modify the interest rates on loans to rates that are below market rates. Furthermore, we are committed to collecting on all of our loans and, as a result, at times have lower net charge-offs compared to many of our peer banks. We believe that our commitment to collecting on all of our loans results in higher loan recoveries. 39 Table of Contents ​ Our nonperforming assets consist of nonperforming loans and foreclosed real estate. Nonperforming loans are those on which the accrual of interest has stopped, as well as loans that are contractually 90 days past due on which interest continues to accrue. The composition of our nonperforming assets is as follows: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ As of March 31, As of December 31, As of March 31, ​ ​ 2025 ​ 2024 ​ 2024 ​ (dollars in thousands) ​ Nonperforming loans ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Nonaccrual loans ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Commercial & industrial ​ $ 789 ​ $ 794 ​ $ 4,601 ​ Commercial real estate ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Owner Occupied ​ ​ 4,090 ​ ​ 4,999 ​ ​ 2,754 ​ Non-owner Occupied ​ ​ 493 ​ ​ 493 ​ ​ — ​ Multi-family ​ ​ — ​ ​ — ​ ​ — ​ Construction & Development ​ ​ — ​ ​ — ​ ​ — ​ Residential 1-4 family ​ ​ 988 ​ ​ 511 ​ ​ 244 ​ Consumer and other ​ ​ 36 ​ ​ 29 ​ ​ 11 ​ Total nonaccrual loans ​ ​ 6,396 ​ ​ 6,826 ​ ​ 7,610 ​ Loans past due > 90 days, but still accruing ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Commercial & industrial ​ ​ 48 ​ ​ 328 ​ ​ — ​ Commercial real estate ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Owner Occupied ​ ​ — ​ ​ — ​ ​ 1,560 ​ Non-owner Occupied ​ ​ — ​ ​ — ​ ​ — ​ Multi-family ​ ​ — ​ ​ — ​ ​ — ​ Construction & Development ​ ​ — ​ ​ — ​ ​ — ​ Residential 1-4 family ​ ​ 346 ​ ​ 1,294 ​ ​ 703 ​ Consumer and other ​ ​ 24 ​ ​ 48 ​ ​ 4 ​ Total loans past due > 90 days, but still accruing ​ ​ 418 ​ ​ 1,670 ​ ​ 2,267 ​ Total nonperforming loans ​ $ 6,814 ​ $ 8,496 ​ $ 9,877 ​ OREO ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Commercial real estate owned ​ $ — ​ $ — ​ $ — ​ Residential real estate owned ​ ​ — ​ ​ — ​ ​ — ​ Acquired bank property real estate owned ​ ​ 741 ​ ​ 741 ​ ​ 2,674 ​ Total OREO ​ $ 741 ​ $ 741 ​ $ 2,674 ​ Total nonperforming assets ("NPAs") ​ $ 7,555 ​ $ 9,237 ​ $ 12,551 ​ Accruing modified loans to borrowers experiencing financial difficulty ​ $ 15 ​ $ 16 ​ $ 20 ​ Ratios ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Nonaccrual loans to total loans ​ ​ 0.18 % ​ 0.19 % ​ 0.22 % NPAs to total loans plus OREO ​ ​ 0.21 % ​ 0.26 % ​ 0.37 % NPAs to total assets ​ ​ 0.17 % ​ 0.21 % ​ 0.31 % ACL - Loans to nonaccrual loans ​ ​ 684 % ​ 647 % ​ 583 % ACL - Loans to total loans ​ ​ 1.23 % ​ 1.26 % ​ 1.31 % ​ Nonaccrual Loans Loans are typically placed on nonaccrual status when any payment of principal and/or interest is 90 days or more past due, unless the collateral is sufficient to cover both principal and interest and the loan is in the process of collection. Loans are also placed on nonaccrual status when management believes, after considering economic and business conditions, that the principal or interest will not be collectible in the normal course of business. We monitor closely the performance of our loan portfolio. In addition to the monitoring and review of loan performance internally, we have also contracted with an independent organization to review our commercial and retail loan portfolios. The status of delinquent loans, as well as situations identified as potential problems, are reviewed on a regular basis by senior management. The decrease in the amount of nonaccrual loans was primarily due to the improvement in one customer relationship, which resulted in the loan being returned to accrual status. 40 Table of Contents ​ ALLOWANCE FOR CREDIT LOSSES - LOANS The Company assesses the adequacy of its ACL - Loans at the end of each calendar quarter. The level of ACL - Loans is based on the Company’s evaluation of historical default and loss experience, current and projected economic conditions, asset quality trends, known and inherent risks in the portfolio, adverse situations that may affect the borrowers’ ability to repay a loan, the estimated value of any underlying collateral, composition of the loan portfolio and other relevant factors. The ACL - Loans is increased by a provision for credit losses, which is charged to expense, when the analysis shows that an increase is warranted. The ACL – Loans is reduced by charge-offs, net of recoveries, when they occur. The ACL is believed adequate to absorb all expected future losses to be recognized over the contractual life of the loans in the portfolio. For further details on the Company’s ACL – Loans, refer to the footnotes along with the consolidated financial statements elsewhere in this report. At March 31, 2025, the ACL - Loans was $43.7 million (representing 1.23% of period end loans). Bank First recorded a provision for credit losses of $0.4 million during the first three quarters of 2025. The ACL– Loans has remained consistent over recent quarters as economic conditions have remained stable and the Company’s overall asset quality remain strong. The Company recorded net charge-offs totaling $0.8 million during the first three months of 2025.

Deposits have traditionally been our primary source of funds for our investment and lending activities. We also borrow from the FHLB of Chicago to supplement cash needs, to lengthen the maturities of liabilities for interest rate risk management purposes and to manage our cost of funds. Our additional sources of funds are scheduled payments and prepayments of principal and interest on loans and investment securities and fee income and proceeds from the sales of loans and securities. Deposits. Our current deposit products include non-interest bearing and interest-bearing checking accounts, savings accounts, money market accounts, and certificate of deposits. As of March 31, 2025, deposit liabilities accounted for approximately 81.6% of our total liabilities and equity. We accept deposits primarily from customers in the communities in which our branches and offices are located, as well as from small businesses and other customers throughout our lending area. We rely on our competitive pricing and products, quality customer service, and convenient locations and hours to attract and retain deposits. Deposit rates and terms are based primarily on current business strategies, market interest rates, liquidity requirements and our deposit growth goals. ​ Total deposits were $3.67 billion and $3.66 billion as of March 31, 2025 and December 31, 2024, respectively. Noninterest-bearing deposits at March 31, 2025 and December 31, 2024, were $993.8 million and $1.02 billion, respectively, while interest-bearing deposits were $2.68 billion and $2.64 billion at March 31, 2025 and December 31, 2024, respectively. The Bank continue to see a shift in its deposit portfolio from noninterest-bearing deposits to interest-bearing deposits as prevailing interest rates have increased over the last several years. ​ At March 31, 2025, we had a total of $662.5 million in certificates of deposit, including $20.1 million of brokered deposits. Based on historical experience and our current pricing strategy, we believe we will retain a majority of these accounts upon maturity, although our long-term strategy is to minimize reliance on certificates of deposits by increasing relationship deposits in lower earning savings and demand deposit accounts. ​ 42 Table of Contents ​ The following tables set forth the average balances of our deposits for the periods indicated: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Three months ended Year ended Three months ended ​ ​ ​ March 31, 2025 December 31, 2024 March 31, 2024 ​ ​ Amount Percent Amount Percent Amount Percent ​ ​ (dollars in thousands) ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Noninterest-bearing demand deposits $ 981,823 26.8 % $ 1,000,772 29.0 % $ 983,104 28.5 % ​ Interest-bearing checking deposits ​ 516,658 14.1 % 401,990 11.6 % 421,776 12.3 % ​ Savings deposits ​ 831,083 22.6 % 816,410 23.6 % 812,947 23.6 % ​ Money market accounts ​ 683,446 18.6 % 616,964 17.9 % 637,454 18.5 % ​ Certificates of deposit ​ 638,937 17.4 % 613,593 17.7 % 590,116 17.1 % ​ Brokered deposits ​ 20,092 0.5 % 7,662 0.2 % 748 — % ​ Total ​ $ 3,672,039 100 % $ 3,457,391 ​ 100 % $ 3,446,145 100 % ​ ​ The following table provides information on maturities of certificates of deposits which exceed FDIC insurance limits of $250,000 as of March 31, 2025: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Time Deposits over FDIC ​ Portion of Time Deposits in ​ ​ Insurance Limits Excess of FDIC Insurance Limits ​ (dollars in thousands) 3 months or less remaining ​ $ 60,052 ​ $ 26,802 Over 3 to 6 months remaining ​ 64,736 ​ 37,236 Over 6 to 12 months remaining ​ 32,607 ​ 14,357 Over 12 months or more remaining ​ 16,052 ​ 8,052 Total ​ $ 173,447 ​ $ 86,447 ​ Borrowings ​ The Company’s borrowings have historically consisted primarily of FHLB of Chicago advances collateralized by a blanket pledge agreement on the Company’s FHLB capital stock and retail and commercial loans held in the Company’s portfolio. There were $134.9 million and $135.4 million of advances outstanding from the FHLB at March 31, 2025 and December 31, 2024, respectively. ​ The total loans pledged as collateral were $1.14 billion and $1.47 billion at March 31, 2025 and December 31, 2024. There were no outstanding letters of credit from the FHLB at March 31, 2025 or December 31, 2024. ​ The following table summarizes borrowings from the FHLB, and the weighted average interest rates paid: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Three months ended ​ Year ended ​ Three months ended ​ ​ (dollars in thousands) March 31, 2025 December 31, 2024 March 31, 2024 ​ ​ Average daily amount of borrowings outstanding during the period ​ $ 134,966 ​ $ 85,762 ​ $ 35,281 ​ ​ Weighted average interest rate on average daily borrowing ​ 4.53 % 4.42 % 3.97 % ​ Maximum outstanding borrowings at any month-end ​ $ 134,890 ​ $ 135,372 ​ $ 35,295 ​ ​ Borrowing outstanding at period end ​ $ 134,890 ​ $ 135,372 ​ $ 35,295 ​ ​ Weighted average interest rate on borrowing at period end ​ 4.39 % 4.37 % 3.59 % ​ ​ Lines of credit and other borrowings. During July 2020, the Company entered into subordinated note agreements with two separate commercial banks. As of March 31, 2025 and December 31, 2024, outstanding balances under these agreements totaled $6.0 million. These notes were issued with 10-year maturities, will carry interest at a fixed rate of 5.0% through June 30, 2025, and at a variable rate thereafter, payable quarterly. These notes are callable on or after January 1, 2026 and qualify for Tier 2 capital for regulatory purposes. 43 Table of Contents ​ During August 2022, the Company entered into subordinated note agreements with an individual. As of March 31, 2025 and December 31, 2024, outstanding balances under these agreements totaled $6.0 million.

These notes are callable on or after August 6, 2027 and qualify for Tier 2 capital for regulatory purposes. INVESTMENT SECURITIES Our securities portfolio consists of securities available for sale and securities held to maturity. Securities are classified as held to maturity or available for sale at the time of purchase. Obligations of states and political subdivisions and mortgage-backed securities, all of which are issued by U.S. government agencies or U.S. government-sponsored enterprises, make up the largest components of the securities portfolio. We manage our investment portfolio to provide an adequate level of liquidity as well as to maintain neutral interest rate-sensitive positions, while earning an adequate level of investment income without taking undue or excessive risk. Securities available for sale consist of U.S. government sponsored agencies, obligations of states and political subdivision, mortgage-backed securities, and corporate notes. Securities classified as available for sale, which management has the intent and ability to hold for an indefinite period of time, but not necessarily to maturity, are carried at fair value, with unrealized gains and losses, net of related deferred income taxes, included in stockholders’ equity as a separate component of other comprehensive income. The fair value of securities available for sale totaled $163.7 million and included negligible gross unrealized gains and gross unrealized losses of $11.9 million at March 31, 2025. At December 31, 2024, the fair value of securities available for sale totaled $223.1 million and included negligible gross unrealized gains and gross unrealized losses of $12.9 million. ​ Securities classified as held to maturity consist of U.S. treasury securities and obligations of states and political subdivisions. These securities, which management has the intent and ability to hold to maturity, are reported at amortized cost. Securities held to maturity totaled $110.2 million at March 31, 2025 and $110.8 million at December 31, 2024. ​ The Company had recognized no net losses on sales of securities during the three months ended March 31, 2025. The Company had recognized net losses on sales of securities of $0.03 million during the three months ended March 31, 2024. ​ The following tables set forth the composition and maturities of investment securities as of March 31, 2025 and December 31, 2024. Actual maturities may differ from contractual maturities because borrowers may have the right to call or prepay obligations with or without call or prepayment penalties. ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ After One, But ​ After Five, But ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Within One Year ​ Within Five Years ​ Within Ten Years ​ After Ten Years ​ Total ​ ​ ​ ​ ​ Weighted ​ ​ ​ ​ Weighted ​ ​ ​ ​ Weighted ​ ​ ​ ​ Weighted ​ ​ ​ ​ Weighted ​ ​ Amortized ​ Average ​ Amortized ​ Average ​ Amortized ​ Average ​ Amortized ​ Average ​ Amortized ​ Average At March 31, 2025 Cost Yield (1) Cost Yield (1) Cost Yield (1) Cost Yield (1) Cost Yield (1) ​ ​ (dollars in thousands) ​ Available for sale securities ​ ​ ​ ​ ​ ​ Obligations of U.S. Government sponsored agencies ​ ​ 499 4.9 % ​ 11,321 4.1 % ​ 12,965 1.9 % ​ 10,188 2.2 % ​ 34,973 2.8 % Obligations of states and political subdivisions ​ 830 3.8 % 11,938 4.1 % 22,944 3.3 % 26,928 2.8 % 62,640 3.2 % Mortgage-backed securities ​ 5,012 4.4 % 38,866 3.0 % 7,899 4.5 % 10,588 3.7 % 62,365 3.4 % Corporate notes ​ — — % 5,000 8.7 % 9,603 3.3 % 1,067 10.2 % 15,670 5.5 % Total available for sale securities ​ $ 6,341 4.4 % $ 67,125 3.8 % $ 53,411 3.1 % $ 48,771 3.0 % $ 175,648 3.4 % Held to maturity securities ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ U.S. Treasury securities ​ $ 23,598 3.5 % $ 37,027 3.9 % $ 46,421 4.4 % $ — — % $ 107,046 4.0 % Obligations of states and political subdivisions ​ ​ 1,491 2.4 % ​ 1,704 2.8 % ​ — — % ​ — — % ​ 3,195 ​ 2.6 % Total held to maturity securities ​ $ 25,089 ​ 3.4 % $ 38,731 ​ 3.8 % $ 46,421 4.4 % $ — — % $ 110,241 ​ 4.0 % Total ​ $ 31,430 4.2 % $ 105,856 4.7 % $ 99,832 3.7 % $ 48,771 3.0 % $ 285,889 3.8 % ​ 44 Table of Contents ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ After One, But ​ After Five, But ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Within One Year ​ Within Five Years ​ Within Ten Years ​ After Ten Years ​ Total ​ ​ ​ ​ ​ Weighted ​ ​ ​ ​ Weighted ​ ​ ​ ​ Weighted ​ ​ ​ ​ Weighted ​ ​ ​ ​ Weighted ​ ​ Amortized ​ Average ​ Amortized ​ Average ​ Amortized ​ Average ​ Amortized ​ Average ​ Amortized ​ Average At December 31, 2024 Cost Yield (1) Cost Yield (1) Cost Yield (1) Cost Yield (1) Cost Yield (1) ​ (dollars in thousands) ​ Available for sale securities ​ ​ ​ ​ ​ ​ U.S. Treasury securities $ 99,656 4.2 % $ — — % $ — — % $ — — % $ 99,656 4.2 % Obligations of U.S. Government sponsored agencies ​ ​ 1,493 5.0 % ​ 1,200 4.5 % ​ 13,761 2.0 % ​ 11,312 2.2 % ​ 27,766 2.3 % Obligations of states and political subdivisions ​ 344 4.9 % 11,970 4.1 % 18,853 3.1 % 31,825 2.8 % 62,992 3.2 % Mortgage-backed securities ​ 45 3.5 % 10,598 3.4 % 7,979 4.4 % 11,204 3.7 % 29,826 3.8 % Corporate notes ​ — — % 5,000 8.7 % 9,606 3.3 % 1,063 10.3 % 15,669 5.5 % Total available for sale securities ​ $ 101,538 4.2 % $ 28,768 4.7 % $ 50,199 3.0 % $ 55,404 3.0 % $ 235,909 3.7 % Held to maturity securities ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ U.S. Treasury securities $ 22,671 3.6 % $ 40,574 3.7 % $ 44,316 4.3 % $ — — % $ 107,561 3.9 % Obligations of states and political subdivisions ​ ​ 800 2.3 % ​ 2,395 2.7 % ​ — — % ​ — — % ​ 3,195 ​ 2.6 % Total held to maturity securities ​ $ 23,471 ​ 3.5 % $ 42,969 ​ 3.7 % $ 44,316 4.3 % $ — — % $ 110,756 ​ 3.9 % Total ​ $ 125,009 4.1 % $ 71,737 4.1 % $ 94,515 3.6 % $ 55,404 3.0 % $ 346,665 3.8 % (1) Weighted Average Yield is shown on a fully taxable equivalent basis using a federal tax rate of 21% and includes the amortization of premiums and discounts. As of March 31, 2025 and December 31, 2024, no allowance for credit losses on securities AFS was recognized. The Company does not consider its securities AFS with unrealized losses to be attributable to credit-related factors, as the unrealized losses in each category have occurred as a result of changes in noncredit-related factors such as changes in interest rates, market spreads and market conditions subsequent to purchase, not credit deterioration. Furthermore, as of March 31, 2025, the Company did not have the intent to sell any of these securities AFS and believes that it is more likely than not that we will not have to sell any such securities before a recovery of cost. The Company does not believe there are any expected credit losses in its HTM securities portfolio at March 31, 2025 or December 31, 2024. All U.S. Treasury securities have the full faith and credit backing of the United States government and the amount of obligations of states and political subdivisions in an unrealized loss position is immaterial to the financial statements. As of March 31, 2025, 203 debt securities had gross unrealized losses, with an aggregate depreciation of 4.2% from our amortized cost basis. The largest unrealized loss percentage of any single security was 23.4% (or $0.5 million) of its amortized cost. The largest unrealized dollar loss of any security was $0.8 million (or 22.1%). As of December 31, 2024, 210 debt securities had gross unrealized losses, with an aggregate depreciation of 4.1% from our amortized cost basis. The largest unrealized loss percentage of any single security was 24.6% (or $0.5 million) of its amortized cost. The largest unrealized dollar loss of any single security was $0.9 million (or 23.5%). The unrealized losses on these debt securities arose primarily due to changing interest rates and are considered to be temporary. 45 Table of Contents ​ LIQUIDITY AND CAPITAL RESOURCES Impact of Inflation and Changing Prices. Our consolidated financial statements and related notes have been prepared in accordance with GAAP. GAAP generally requires the measurement of financial position and operating results in terms of historical dollars without consideration of changes in the relative purchasing power of money over time due to inflation. The impact of inflation is reflected in the increased cost of our operations. Unlike industrial companies, our assets and liabilities are primarily monetary in nature. As a result, changes in market interest rates have a greater impact on our performance than they would on industrial companies. Liquidity. Liquidity is defined as the Company’s ability to generate adequate cash to meet its needs for day-to-day operations and material long and short-term commitments. Liquidity is the risk of potential loss if we were unable to meet our funding requirements at a reasonable cost. We are expected to maintain adequate liquidity at the Bank to meet the cash flow requirements of customers who may be either depositors wishing to withdraw funds or borrowers needing assurance that sufficient funds will be available to meet their credit needs. Our asset and liability management policy is intended to cause the Bank to maintain adequate liquidity and, therefore, enhance our ability to raise funds to support asset growth, meet deposit withdrawals and lending needs, maintain reserve requirements and otherwise sustain our operations. We continuously monitor our liquidity position to ensure that assets and liabilities are managed in a manner that will meet all of our short-term and long-term cash requirements. We manage our liquidity based on demand and specific events and uncertainties to meet current and future financial obligations of a short-term nature. We also monitor our liquidity requirements in light of interest rate trends, changes in the economy and the scheduled maturity and interest rate sensitivity of the investment and loan portfolios and deposits. Our objective in managing liquidity is to respond to the needs of depositors and borrowers as well as to increase earnings enhancement opportunities in a changing marketplace. Our liquidity is maintained through our investment portfolio, deposits, borrowings from the FHLB, and lines available from correspondent banks. Our highest priority is placed on growing noninterest bearing deposits through strong community involvement in the markets that we serve. Borrowings and brokered deposits are considered short-term supplements to our overall liquidity but are not intended to be relied upon for long-term needs. The Company currently has $1.54 billion in availability between borrowings and brokered deposits for future funding if liquidity needs were to develop. We believe that our present position is adequate to meet our current and future liquidity needs, and management knows of no trend or event that will have a material impact on the Company’s ability to maintain liquidity at satisfactory levels. Capital Adequacy. Total stockholders’ equity was $648.4 million at March 31, 2025 compared to $639.7 million at December 31, 2024. Our capital management consists of providing adequate equity to support our current and future operations. The Bank is subject to various regulatory capital requirements administered by state and federal banking agencies, including the Federal Reserve and the OCC. Failure to meet minimum capital requirements may prompt certain actions by regulators that, if undertaken, could have a direct material adverse effect on our financial condition and results of operations. Under capital adequacy guidelines and the regulatory framework for prompt corrective action, the Bank must meet specific capital guidelines that involve quantitative measure of their assets, liabilities, and certain off-balance sheet items as calculated under regulatory accounting practices. The capital amounts and the classifications are also subject to qualitative judgment by the regulator in regard to components, risk weighting and other factors. 46 Table of Contents ​ The Bank is subject to the following risk-based capital ratios: a common equity Tier 1 (“CET1”) risk-based capital ratio, a Tier 1 risk-based capital ratio, which includes CET1 and additional Tier 1 capital, and a total capital ratio, which includes Tier 1 and Tier 2 capital. CET1 is primarily comprised of the sum of common stock instruments and related surplus net of treasury stock, retained earnings, and certain qualifying minority interests, less certain adjustments and deductions, including with respect to goodwill, intangible assets, mortgage servicing assets and deferred tax assets subject to temporary timing differences. Additional Tier 1 capital is primarily comprised of noncumulative perpetual preferred stock, tier 1 minority interests and grandfathered trust preferred securities. Tier 2 capital consists of instruments disqualified from Tier 1 capital, including qualifying subordinated debt, other preferred stock and certain hybrid capital instruments, and a limited amount of loan loss reserves up to a maximum of 1.25% of risk-weighted assets, subject to certain eligibility criteria. The capital rules also define the risk-weights assigned to assets and off-balance sheet items to determine the risk-weighted asset components of the risk-based capital rules, including, for example, certain “high volatility” commercial real estate, past due assets, structured securities and equity holdings. The leverage capital ratio, which serves as a minimum capital standard, is the ratio of Tier 1 capital to quarterly average assets net of goodwill, certain other intangible assets, and certain required deduction items. The required minimum leverage ratio for all banks is 4%. Failure to be well-capitalized or to meet minimum capital requirements could result in certain mandatory and possible additional discretionary actions by regulators that, if undertaken, could have an adverse material effect on our operations or financial condition. For example, only a well-capitalized depository institution may accept brokered deposits without prior regulatory approval. Failure to be well-capitalized or to meet minimum capital requirements could also result in restrictions on the Bank’s ability to pay dividends or otherwise distribute capital or to receive regulatory approval of applications or other restrictions on its growth. The Federal Deposit Insurance Corporation Improvement Act of 1991 (“FDICIA”), among other things, requires the federal bank regulatory agencies to take “prompt corrective action” regarding depository institutions that do not meet minimum capital requirements. FDICIA establishes five regulatory capital tiers: “well capitalized”, “adequately capitalized”, “undercapitalized”, “significantly undercapitalized”, and “critically undercapitalized”. A depository institution’s capital tier will depend upon how its capital levels compare to various relevant capital measures and certain other factors, as established by regulation. FDICIA generally prohibits a depository institution from making any capital distribution (including payment of a dividend) or paying any management fee to its holding company if the depository institution would thereafter be undercapitalized. The FDICIA imposes progressively more restrictive restraints on operations, management and capital distributions, depending on the category in which an institution is classified. Undercapitalized depository institutions are subject to restrictions on borrowing from the Federal Reserve System. In addition, undercapitalized depository institutions may not accept brokered deposits absent a waiver from the FDIC, are subject to growth limitations and are required to submit capital restoration plans for regulatory approval. A depository institution’s holding company must guarantee any required capital restoration plan, up to an amount equal to the lesser of 5 percent of the depository institution’s assets at the time it becomes undercapitalized or the amount of the capital deficiency when the institution fails to comply with the plan. Federal banking agencies may not accept a capital plan without determining, among other things, that the plan is based on realistic assumptions and is likely to succeed in restoring the depository institution’s capital. If a depository institution fails to submit an acceptable plan, it is treated as if it is significantly undercapitalized. All of the federal bank regulatory agencies have adopted regulations establishing relevant capital measures and relevant capital levels for federally insured depository institutions. The Bank was well capitalized at March 31, 2025, and brokered deposits are not restricted. 47 Table of Contents ​ To be well-capitalized, the Bank must maintain at least a 6.5% CET1 to risk-weighted assets ratio, an 8.0% Tier 1 capital to risk-weighted assets ratio, a 10.0% Total capital to risk-weighted assets ratio, and a 5.0% leverage ratio. The Bank’s regulatory capital ratios were above the applicable well-capitalized standards and met the then-applicable capital conservation buffer. Based on current estimates, we believe that the Bank will continue to exceed all applicable well-capitalized regulatory capital requirements and the capital conservation buffer in 2025. As a result of the Economic Growth Act, the federal banking agencies were required to develop a “Community Bank Leverage Ratio” (the ratio of a bank’s Tier 1 capital to average total consolidated assets) for financial institutions with assets of less than $10 billion. A “qualifying community bank” that exceeds this ratio will be deemed to be in compliance with all other capital and leverage requirements, including the capital requirements to be considered “well capitalized” under prompt corrective action statutes. The federal banking agencies may consider a financial institution’s risk profile when evaluation whether it qualifies as a community bank for purposes of the capital ratio requirement. The federal banking agencies set the minimum capital for the new Community Bank Leverage Ratio at 9%. The Bank does not intend to opt into the Community Bank Leverage Ratio Framework. On December 21, 2018, federal banking agencies issued a joint final rule to revise their regulatory capital rules to (i) address the upcoming implementation of CECL accounting standard under GAAP; (ii) provide an optional three-year phase-in period for the day-one adverse regulatory capital effects that banking organizations are expected to experience upon adopting CECL; and (iii) require the use of CECL in stress tests beginning with the 2020 capital planning and stress testing cycle for certain banking organizations. For more information regarding Accounting Standards Update No. 2016-13, which introduced CECL as the methodology to replace the current “incurred loss” methodology for financial assets measured at amortized cost, and changed the approaches for recognizing and recording credit losses on available-for-sale debt securities and purchased credit impaired financial assets, including the required implementation date for the Company, see the Company’s Annual Report. Federal banking regulators have issued risk-based capital guidelines, which assign risk factors to asset categories and off-balance-sheet items.

These financial instruments primarily include commitments to originate and sell loans, standby and direct pay letters of credit, unused lines of credit and unadvanced portions of construction and development loans. The instruments involve, to varying degrees, elements of credit and interest rate risk in excess of the amount recognized in the consolidated balance sheet. The contract or notional amounts of those instruments reflect the extent of involvement the Company has in these particular classes of financial instruments. Our exposure to credit loss in the event of nonperformance by the other party to the financial instrument for loan commitments, standby and direct pay letters of credit and unadvanced portions of construction and development loans is represented by the contractual amount of those instruments. The Company uses the same credit policies in making commitments and conditional obligations as it does for on-balance-sheet instruments. Off-Balance Sheet Arrangements. Our significant off-balance-sheet arrangements consist of the following: ● Unused lines of credit ● Standby and direct pay letters of credit ● Credit card arrangements Off-balance sheet arrangement means any transaction, agreement or other contractual arrangement to which an entity unconsolidated with the registrant is a party, under which the registrant has (1) any obligation under a guarantee contract, (2) retained or contingent interest in assets transferred to an unconsolidated entity or similar arrangement, (3) any obligation, including a contingent obligation, under a contract that would be accounted for as a derivative instrument, or (4) any obligation, including a contingent obligation, arising out of a variable interest. Loan commitments are made to accommodate the financial needs of our customers. Standby and direct pay letters of credit commit us to make payments on behalf of customers when certain specified future events occur. Both arrangements have credit risk essentially the same as that involved in extending loans to clients and are subject to our normal credit policies. Collateral (e.g., securities, receivables, inventory, equipment, etc.) is obtained based on management’s credit assessment of the customer. Loan commitments and standby and direct pay letters of credit do not necessarily represent our future cash requirements because while the borrower has the ability to draw upon these commitments at any time, these commitments often expire without being drawn upon. Our off-balance sheet arrangements as of March 31, 2025, were as follows: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Amounts of Commitments Expiring - By Period as of March 31, 2025 ​ ​ ​ ​ Less Than One One to Three Three to Five ​ Other Commitments ​ Total Year Years Years After Five Years ​ (dollars in thousands) Unused lines of credit ​ $ 760,219 ​ $ 426,862 ​ $ 109,118 ​ $ 27,779 ​ $ 196,460 Standby and direct pay letters of credit ​ 10,046 ​ 8,696 ​ 545 ​ 625 ​ 180 Credit card arrangements ​ 24,384 ​ — ​ — ​ — ​ 24,384 Total commitments ​ $ 794,649 ​ $ 435,558 ​ $ 109,663 ​ $ 28,404 ​ $ 221,024 ​ ​ ​ ​ 49 Table of Contents ​ ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK Market risk is the risk of loss from adverse changes in market prices and rates. Our market risk arises primarily from interest rate risk inherent in its lending, investment and deposit-taking activities. To that end, management actively monitors and manages its interest rate risk exposure. Our profitability is affected by fluctuations in interest rates. A sudden and substantial change in interest rates may adversely impact our earnings to the extent that the interest rates borne by assets and liabilities do not change at the same speed, to the same extent or on the same basis. We monitor the impact of changes in interest rates on its net interest income using several tools. Our primary objective in managing interest rate risk is to minimize the adverse impact of changes in interest rates on our net interest income and capital, while configuring our asset-liability structure to obtain the maximum yield-cost spread on that structure. We rely primarily on our asset-liability structure to control interest rate risk. Interest Rate Sensitivity. Interest rate risk is the risk to earnings and value arising from changes in market interest rates. Interest rate risk arises from timing differences in the repricings and maturities of interest-earning assets and interest-bearing liabilities (repricing risk), changes in the expected maturities of assets and liabilities arising from embedded options, such as borrowers’ ability to prepay home mortgage loans at any time and depositors’ ability to redeem certificates of deposit before maturity (option risk), changes in the shape of the yield curve where interest rates increase or decrease in a nonparallel fashion (yield curve risk), and changes in spread relationships between different yield curves, such as U.S. Treasuries (basis risk). An asset sensitive position refers to a balance sheet position in which an increase in short-term interest rates is expected to generate higher net interest income, as rates earned on our interest-earning assets would reprice upward more quickly than rates paid on our interest-bearing liabilities, thus expanding our net interest margin. Conversely, a liability sensitive position refers to a balance sheet position in which an increase in short-term interest rates is expected to generate lower net interest income, as rates paid on our interest-bearing liabilities would reprice upward more quickly than rates earned on our interest-earning assets, thus compressing our net interest margin. The Company actively manages its interest rate sensitivity position. The objectives of interest rate risk management are to control exposure of net interest income to risks associated with interest rate movements and to achieve sustainable growth in net interest income. The Company’s ALCO, using policies and procedures approved by the Company’s board of directors, is responsible for the management of the Company’s interest rate sensitivity position. The Company manages interest rate sensitivity by changing the mix, pricing and re-pricing characteristics of its assets and liabilities, through the management of its investment portfolio, its offerings of loan and selected deposit terms and through wholesale funding. Wholesale funding consists of, but is not limited to, multiple sources including borrowings with the FHLB of Chicago, the Federal Reserve Bank of Chicago’s discount window and certificates of deposit from institutional brokers. The Company uses several tools to manage its interest rate risk including interest rate sensitivity analysis, or gap analysis, market value of portfolio equity analysis, interest rate simulations under various rate scenarios and net interest margin reports. The results of these reports are compared to limits established by the Company’s ALCO policies and appropriate adjustments are made if the results are outside the established limits. There are an infinite number of potential interest rate scenarios, each of which can be accompanied by differing economic/political/regulatory climates; can generate multiple differing behavior patterns by markets, borrowers, depositors, etc.; and, can last for varying degrees of time. Therefore, by definition, interest rate risk sensitivity cannot be predicted with certainty. Accordingly, the Company’s interest rate risk measurement philosophy focuses on maintaining an appropriate balance between theoretical and practical scenarios; especially given the primary objective of the Company’s overall asset/liability management process is to facilitate meaningful strategy development and implementation. Therefore, we model a set of interest rate scenarios capturing the financial effects of a range of plausible rate scenarios; the collective impact of which will enable the Company to clearly understand the nature and extent of its sensitivity to interest rate changes. Doing so necessitates an assessment of rate changes over varying time horizons and of varying/sufficient degrees such that the impact of embedded options within the balance sheet are sufficiently examined. 50 Table of Contents ​ The following tables demonstrate the annualized result of an interest rate simulation and the estimated effect that a parallel interest rate shift, or “shock,” in the yield curve and subjective adjustments in deposit pricing might have on the Company’s projected net interest income over the next 12 months. This simulation assumes that there is no growth in interest-earning assets or interest-bearing liabilities over the next 12 months. The changes to net interest income shown below are in compliance with the Company’s policy guidelines. ​ As of March 31, 2025: ​ ​ ​ ​ Change in Interest Rates Percentage Change in (in Basis Points) Net Interest Income +300 (4.9)% +200 (3.3)% +100 (1.6)% -100 (0.8)% -200 (1.4)% -300 ​ (1.2)% ​ As of December 31, 2024: ​ ​ ​ ​ Change in Interest Rates Percentage Change in (in Basis Points) ​ Net Interest Income +300 (4.5)% +200 (3.0)% +100 (1.5)% -100 ​ (1.3)% -200 ​ (2.1)% -300 (2.1)% ​ ​ Economic Value of Equity Analysis. We also analyze the sensitivity of the Company’s financial condition to changes in interest rates through our economic value of equity model. This analysis measures the difference between estimated changes in the present value of the Company’s assets and estimated changes in the present value of the Company’s liabilities assuming various changes in current interest rates. The Company’s economic value of equity analysis as of March 31, 2025 estimated that, in the event of an instantaneous 200 basis point increase in interest rates, the Company would experience a 3.14% increase in the economic value of equity. At the same date, our analysis estimated that, in the event of an instantaneous 100 basis point decrease in interest rates, the Company would experience a 3.20% decrease in the economic value of equity. The estimates of changes in the economic value of our equity require us to make certain assumptions including loan and mortgage-related investment prepayment speeds, reinvestment rates, and deposit maturities and decay rates. These assumptions are inherently uncertain and, as a result, we cannot precisely predict the impact of changes in interest rates on the economic value of our equity. Although our economic value of equity analysis provides an indication of our interest rate risk exposure at a particular point in time, such estimates are not intended to, and do not, provide a precise forecast of the effect of changes in market interest rates on the economic value of our equity and will differ from actual results. ​ 51 Table of Contents ​ ITEM 4. CONTROLS AND PROCEDURES Evaluation of Disclosure Controls and Procedures Management, including our Chief Executive Officer (“CEO”) and our Chief Financial Officer (“CFO”), undertook an evaluation of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”)) as of the end of the period covered by this report, and, based on that evaluation, our CEO and CFO concluded that our disclosure controls and procedures were effective as of the end of the period covered by this report, in recording, processing, summarizing and reporting in a timely manner the information that the Company is required to disclose in its reports under the Exchange Act and in accumulating and communicating to the Company’s management, including the Company’s CEO and CFO, such information as appropriate to allow timely decisions regarding required disclosure. Changes in Internal Control Over Financial Reporting No changes were made to our internal control over financial reporting (as defined in Rule 13a-15(f) under the Exchange Act) during the quarter ended March 31, 2025 that materially affected, or are reasonably likely to materially affect, our internal control over financial reporting. Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate. ​ PART II. OTHER INFORMATION ITEM 1. LEGAL PROCEEDINGS We are a party to various litigation in the normal course of business. Management, after consulting with our legal counsel, believes that any liability resulting from litigation will not have a material effect on our financial position, results of operations or liquidity. ​ ITEM 1A. RISK FACTORS Additional information regarding risk factors appears in “Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations - Forward-Looking Statements” of this Form 10-Q and in “Item 1A. Risk Factors” in our Annual Report on Form 10-K for the year ended December 31, 2024. There have been no material changes during the quarterly period ended March 31, 2025 to the risk factors previously disclosed in the Company’s Annual Report. ​ 52 Table of Contents ​ ITEM 2. UNREGISTERED SALES OF EQUITY SECURITIES AND USE OF PROCEEDS (a) None. (b) None. (c) Issuer Purchases of Equity Securities On February 18, 2025, the Company renewed its share repurchase program, pursuant to which the Company may repurchase up to $50 million of its common stock, par value $0.01 per share, for a period of one (1) year, ending on February 17, 2026. The program was announced in a Current Report on Form 8-K on February 18, 2025. The table below sets forth information regarding repurchases of our common stock during the first quarter of 2025 under that program as well as pursuant to the 2020 Equity Plan and other repurchases. ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Total Number Maximum Number ​ ​ ​ ​ ​ ​ ​ of Shares Repurchased as ​ of Shares ​ ​ ​ ​ ​ ​ ​ Part of ​ that May Yet Be ​ ​ Total Number of Shares ​ Average Price Paid per ​ Publicly Announced ​ Purchased Under the (in thousands, except per share data) ​ Repurchased ​ Share (1) ​ Plans or Programs ​ Plans or Programs (2) January 2025 7,001 ​ $ 94.47 7,001 168,610 February 2025 11,083 ​ 103.37 11,083 496,327 March 2025 44,480 ​ 102.82 44,480 451,847 Total 62,564 ​ $ 100.22 62,564 451,847 (1) The average price paid per share is calculated on a trade date basis for all open market transactions and excludes commissions and other transaction expenses. (2) Based on the closing per share price as of March 31, 2025 ($100.74). ​ The Inflation Reduction Act of 2022 (“IRA”) created a new nondeductible 1% excise tax on repurchases of corporate stock by certain publicly traded corporations or their specified affiliates after December 31, 2022. The tax is imposed on the fair value of the stock of a covered corporation that is repurchased in a given year, less the fair market value of any stock issued in that year. The Company falls under the definition of a “covered corporation”. The excise tax applies to all of the stock of a covered corporation regardless of whether the corporation has profits or losses. The impact of the IRA on our consolidated financial statements will be dependent on the extent of stock repurchases made in current and future periods. ​ ​ ITEM 3.
