(“NBT Financial”), NBT Holdings, Inc. (“NBT Holdings”), CNBF Capital Trust I, NBT Statutory Trust I, NBT Statutory Trust II, Alliance Financial Capital Trust I, Alliance Financial Capital Trust II and Evans Capital Trust I (collectively, the “Trusts”) .

Summary of Significant Accounting Policies Basis of Presentation The accompanying unaudited interim consolidated financial statements include the accounts of NBT Bancorp Inc. and its wholly-owned subsidiaries mentioned above. In the opinion of management, the interim data includes all adjustments, consisting only of normal recurring adjustments, necessary for a fair presentation of the results for the interim periods in accordance with U.S. generally accepted accounting principles (“GAAP”) and in accordance with the instructions for the Quarterly Report on Form 10-Q and Article 10 of Regulation S-X as promulgated by the Securities and Exchange Commission (“SEC”). Accordingly, the consolidated financial statements do not include all of the information and notes necessary for complete financial statements in conformity with GAAP. These unaudited interim consolidated financial statements should be read in conjunction with the audited consolidated financial statements and notes thereto included in the Company’s 2024 Annual Report on Form 10-K. The results of operations for the interim periods are not necessarily indicative of the results that may be expected for the full year or any other interim period. All material intercompany transactions have been eliminated in consolidation. Amounts previously reported in the consolidated financial statements are reclassified whenever necessary to conform to current period presentation. The Company has evaluated subsequent events for potential recognition and/or disclosure, and none were identified. Use of Estimates in the Preparation of Financial Statements The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts in the financial statements and accompanying notes. Actual results may differ from those estimates and such differences could be material to the financial statements. Estimates associated with the allowance for credit losses are particularly susceptible to material change in the near term. 3. Recent Accounting Pronouncements Accounting Standards Issued Not Yet Adopted In December 2023, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2023-09, Improvements to Income Tax Disclosures , in response to requests from investors, lenders, creditors and other allocators of capital for enhanced income tax disclosures to support capital allocation decisions. The ASU requires enhanced disclosures primarily related to existing rate reconciliation and income taxes paid information to help investors better assess how the Company’s operations and related tax risks and tax planning and operational opportunities affect the Company’s tax rate and prospects for future cash flows. The ASU 2023-09 improves the transparency of income tax disclosures. The amendments in this ASU are effective for the Company for annual periods beginning after December 15, 2024, and should be applied on a prospective basis. Retrospective application and early adoption are permitted. Aside from complying with the new disclosure requirements, the adoption is not expected to have a material impact on the consolidated financial statements. In November 2024, the FASB issued ASU 2024-03, Income Statement-Reporting Comprehensive Income-Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses , that addresses longstanding investor requests for more information regarding expenses included in the expense captions presented on the face of the income statement. The ASU will require a tabular disclosure that disaggregates certain income statement expenses including employee compensation, depreciation and intangible asset amortization. In January 2025, the FASB issued ASU 2025-01, Income Statement-Reporting Comprehensive Income-Expense Disaggregation Disclosures (Subtopic 220-40): Clarifying the Effective Date, which revises the effective date of ASU 2024-03. The ASU will become effective in the annual reporting periods beginning after December 15, 2026, and early adoption is permitted. Aside from complying with the new disclosure requirements, the adoption is not expected to have a material impact on the consolidated financial statements. 10 Table of Contents 4. Acquisitions Evans Bancorp, Inc. On May 2, 2025 , the Company completed the acquisition of Evans through the merger of Evans with and into the Company, with the Company surviving the merger. Total consideration for the acquisition was $ 221.8 million in common stock. Evans, with assets of $ 2.19 billion at December 31, 2024, was headquartered in Williamsville, New York. Its primary subsidiary, Evans Bank, was a federally-chartered national banking association operating 18 banking locations in Western New York. The acquisition enhances the Company’s presence in Western New York, including the Buffalo and Rochester communities. In connection with the acquisition, the Company issued 5.1 million shares of common stock and acquired approximately $ 130.4 million of identifiable net assets. Preliminary goodwill of $ 91.4 million was recognized as a result of the merger and is not amortizable or deductible for tax purposes. The effects of the acquired assets and liabilities have been included in the consolidated financial statements since May 2, 2025. As a result of the full integration of the operations of Evans, it is not practicable to determine all revenue or net income included in the Company’s operating results relating to Evans since the date of acquisition as Evans results cannot be separately identified. The acquisition of Evans is being accounted for as a business combination in accordance with Accounting Standards Codification (“ASC”) 805, “Business Combinations” (“ASC 805 ”), using the acquisition method of accounting. Accordingly, as of the date of the acquisition, the Company recorded the assets acquired, liabilities assumed and consideration paid at fair value based on management’s best estimates using information available at the date of the acquisition. These estimates are subject to adjustment based on updated information not available at the time of the acquisition. The amount of goodwill arising from the acquisition consists largely of the synergies and economies of scale expected from combining the operations of the Company with Evans. Accrued income taxes and deferred taxes associated with the Evans acquisition were recorded on a provisional basis and could vary from the actual recorded balance once tax provisions and returns are finalized. The following table summarizes the estimated fair value of the assets acquired and liabilities assumed: May 2, 2025 (In thousand s) Evans Bancorp, Inc. Consideration: Cash paid to shareholders (fractional shares) $ 25 Common stock issuance 221,767 Total net consideration $ 221,792 Recognized amounts of identifiable assets acquired and (liabilities) assumed: Cash and cash equivalents $ 40,197 Securities available for sale 255,487 Securities held to maturity 3,494 Loans, net of allowance for credit losses on purchased credit deteriorated loans 1,665,712 Premises and equipment, net 15,069 Core deposit intangibles 33,240 Bank owned life insurance 44,100 Other assets 70,337 Total identifiable assets acquired $ 2,127,636 Deposits $ ( 1,864,049 ) Borrowings ( 113,712 ) Other liabilities ( 19,492 ) Total liabilities assumed $ ( 1,997,253 ) Total identifiable assets, net $ 130,383 Goodwill $ 91,409 11 Table of Contents The following is a description of the valuation methodologies used to estimate the fair values of major categories of assets acquired and liabilities assumed. The Company used an independent valuation specialist to assist with the determination of fair values for certain acquired assets and assumed liabilities. Cash and due from banks - The estimated fair value was determined to approximate the carrying amount of these assets. Securities available for sale (“AFS”) - The estimated fair value of the AFS investment portfolio was primarily determined using quoted market prices and dealer quotes. The investment securities were sold immediately after the merger and no gains or losses were recorded. Securities held to maturity (“HTM”) - The estimated fair value of the HTM investment portfolio, which consisted of local municipal securities, was retained at par, which is estimated to be equal to fair value. Loans - The estimated fair value of loans were based on a discounted cash flow methodology applied on a pooled basis. Loans were first segmented by purchased credit deteriorated (“PCD”) or non-purchased credit deteriorated (“non-PCD”) status, and then further grouped according to Federal Deposit Insurance Corporation (“FDIC”) call report segmentation. The valuation considered key loan characteristics including loan type, term, rate, payment schedule and loan performance attributes. Assumptions related to prepayment speeds, probability of default (“PD”) and loss given default (“LGD”) were also considered. The discount rates applied were based on a build-up approach factoring in the funding mix, servicing costs, liquidity premium and factors related to performance risk. Core deposit intangible - The core deposit intangible was valued utilizing the cost savings method approach, which recognizes the cost savings represented by the expense of maintaining the core deposit base versus the cost of an alternative funding source. The valuation incorporated assumptions related to account retention, discount rates, deposit interest rates, deposit maintenance costs and alternative funding rates. Deposits - The fair value of noninterest bearing demand deposits, interest-bearing checking, money market and savings deposit accounts were assumed to approximate the carrying value as these accounts have no stated maturity and are payable on demand. Certificate of deposit (“CD”) (time deposit accounts) were valued at the present value of the certificates’ expected contractual payments discounted at market rates for similar certificates which approximates carrying value. Borrowings - The estimated fair value of short-term borrowings was determined to approximate stated value. Long-term debt, subordinated debt and junior subordinated debt were valued using a discounted cash flow approach incorporating a discount rate that incorporated similar terms, maturity and credit rating. Accounting for Acquired Loans - Acquired loans are classified into two categories: PCD loans and non-PCD loans. PCD loans are defined as a loan or group of loans that have experienced more than insignificant credit deterioration since origination. Non-PCD loans had an allowance established on acquisition date, which is recognized as an expense through the provision for credit losses. For PCD loans, an allowance is recognized by adding it to the fair value of the loan, which is the amortized cost. There is no provision for credit loss expense recognized on PCD loans because the initial allowance is established by grossing-up the amortized cost of the PCD loan. The allowance for credit losses on non-PCD loans of $ 13.0 million was recorded through the provision for loan losses within the unaudited interim consolidated statements of income. The following table provides details related to the fair value of acquired PCD loans.

AFS debt securities in unrealized loss positions are evaluated for impairment related to credit losses at least quarterly. As of September 30, 2025 and December 31, 2024, the majority of the AFS securities in an unrealized loss position consisted of debt securities issued by U.S. government agencies or U.S. government-sponsored enterprises that carry the explicit and/or implicit guarantee of the U.S. government, which are widely recognized as “risk-free” and have a long history of zero credit losses. Total gross unrealized losses were primarily attributable to changes in interest rates, relative to when the investment securities were purchased, and not due to the credit quality of the investment securities. The Company does not intend to sell, nor is it more likely than not that the Company will be required to sell the securities before recovery of their amortized cost bases, which may be at maturity. The Company elected to exclude accrued interest receivable (“AIR”) from the amortized cost basis of debt securities. AIR on AFS debt securities totaled $ 4.7 million and $ 4.4 million at September 30, 2025 and December 31, 2024, respectively, and is excluded from the estimate of credit losses and reported in the other assets financial statement line. None of the Bank’s HTM debt securities were past due or on nonaccrual status as of September 30, 2025 and December 31, 2024. There was no accrued interest reversed against interest income for the three and nine months ended September 30, 2025 or the year ended December 31, 2024 as all securities remained in accrual status. In addition, there were no collateral-dependent HTM debt securities as of September 30, 2025 and December 31, 2024. There was no allowance for credit losses on HTM securities as of September 30, 2025 and December 31, 2024. As of September 30, 2025 and December 31, 2024, 66 % of the Company’s HTM debt securities were issued by U.S. government agencies or U.S. government-sponsored enterprises with bond ratings of A to AAA. These securities carry the explicit and/or implicit guarantee of the U.S. government, which are widely recognized as “risk-free” and have a long history of zero credit losses. Therefore, the Company did not record an allowance for credit losses for these securities as of September 30, 2025 and December 31, 2024. The remaining HTM debt securities at September 30, 2025 and December 31, 2024 were comprised of state and municipal obligations with bond ratings of A to AAA excluding the $ 79.2 million and $ 84.7 million, respectively, of local municipal bonds which are not rated. Based on the Company’s current expected credit losses (“CECL”) methodology, the expected credit loss on the HTM municipal bond portfolio was deemed immaterial, therefore no allowance for credit loss was recorded as of September 30, 2025 and December 31, 2024. AIR on HTM debt securities totaled $ 3.6 million at September 30, 2025 and $ 4.4 million at December 31, 2024 and is excluded from the estimate of credit losses and reported in the other assets financial statement line. 6. Loans A summary of loans, net of deferred fees and origination costs, by category (1) is as follows: (In thousands) September 30, 2025 December 31, 2024 Commercial & industrial $ 1,644,218 $ 1,426,482 Commercial real estate 4,830,761 3,876,698 Residential mortgage 2,528,565 2,142,249 Home equity 435,584 334,268 Indirect auto 1,327,689 1,273,253 Residential solar 757,982 820,079 Other consumer 70,335 96,881 Total loans $ 11,595,134 $ 9,969,910 (1) Loans are summarized by business line which does not align to how the Company assesses credit risk in the allowance for credit losses under CECL. Included in the above loans are net deferred loan origination (fees) costs totaling $( 41.7 ) million and $( 64.7 ) million at September 30, 2025 and December 31, 2024, respectively. 16 Table of Contents 7. Allowance for Credit Losses and Credit Quality of Loans The allowance for credit losses totaled $ 139.0 million at September 30, 2025, compared to $ 116.0 million at December 31, 2024. The allowance for credit losses as a percentage of loans was 1.20 % at September 30, 2025, compared to 1.16 % at December 31, 2024. The allowance for credit losses calculation incorporated a 6-quarter forecast period to account for forecast economic conditions under each scenario utilized in the measurement. For periods beyond the 6-quarter forecast, the model reverts to long-term economic conditions over a 4-quarter reversion period on a straight-line basis. The Company considers a baseline, upside and downside economic forecast in measuring the allowance. Starting in the second quarter of 2025, the Company included an additional downside scenario with stagflation conditions, which is characterized as an economic environment where inflation rises alongside unemployment. Stagflation was identified as an emerging risk as tariff policies impact the economy . The quantitative model as of September 30, 2025 incorporated a baseline economic outlook along with an alternative upside scenario and two equally weighted downside scenarios, recessionary conditions and stagflation, sourced from a reputable third-party to accommodate other potential economic conditions in the model. At September 30, 2025, the weightings were 65%, 5% and 30% for the baseline, upside and downside economic forecast scenarios, respectively. The baseline outlook reflected an economic environment where the Northeast unemployment rate increases from 4.4% in the fourth quarter of 2025 to 4.8% by the end of the forecast period, with a peak Northeast unemployment rate of 4.9% in the fourth quarter of 2026. National Gross Domestic Product (“GDP’s”) annualized growth (on a quarterly basis) is expected to start the fourth quarter of 2025 at approximately 0.8% and increase to 1.7% by the end of the forecast period. Key assumptions in the baseline economic outlook included the Federal Reserve cutting rates with two 25 basis point cuts at the September and December meetings and the economy remaining at full employment. The alternative upside scenario assumes improved economic conditions from the baseline outlook. Under this scenario, Northeast unemployment falls from 4.3% in the third quarter of 2025 to 3.8% in the first quarter of 2026 and eventually settles at 4.1% by the end of the forecast period. The alternative downside scenario with recessionary conditions assumes deteriorated economic conditions from the baseline outlook. Under this scenario, Northeast unemployment rises from 4.3% in the third quarter of 2025 to a peak of 7.8% in the fourth quarter of 2026. The alternative downside stagflation scenario assumes deteriorated economic conditions from the baseline outlook. Under this scenario, Northeast unemployment rises from 4.3% in the third quarter of 2025 to 6% by the end of the forecast period in the first quarter of 2027, with a peak Northeast unemployment rate of 8.2% in the fourth quarter of 2027. These scenarios and their respective weightings are evaluated at each measurement date and reflect management’s expectations as of September 30, 2025. Additional qualitative adjustments were made for factors not incorporated in the forecasts or the model, such as loss rate expectations for certain loan pools, reversion adjustments for the stagflation scenario and recent trends in asset value indices. Additional monitoring for industry concentrations, loan growth and policy exceptions was also conducted. The quantitative model as of June 30, 2025 incorporated a baseline economic outlook along with an alternative upside scenario and two equally weighted downside scenarios, recessionary conditions and stagflation, sourced from a reputable third-party to accommodate other potential economic conditions in the model. At June 30, 2025, the weightings were 70%, 5% and 25% for the baseline, upside and downside economic forecast scenarios, respectively. The baseline outlook reflected an economic environment where the Northeast unemployment rate increases from 4.3% to 4.8% during the forecast period. National GDP’s annualized growth (on a quarterly basis) is expected to start the third quarter of 2025 at approximately 0.6% and increase to 1.6% by the end of the forecast period. Key assumptions in the baseline economic outlook included the Federal Reserve cutting rates with two 25 basis point cuts at the September and December meetings and the economy remaining at full employment. The alternative upside scenario assumes improved economic conditions from the baseline outlook. Under this scenario, Northeast unemployment falls from 4.3% in the second quarter of 2025 to 3.7% in the fourth quarter of 2025 and eventually settles at 4.1% by the end of the forecast period. The alternative downside scenario with recessionary conditions assumes deteriorated economic conditions from the baseline outlook. Under this scenario, Northeast unemployment rises from 4.3% in the second quarter of 2025 to a peak of 7.7% in the third quarter of 2026. The alternative downside stagflation scenario assumes deteriorated economic conditions from the baseline outlook. Under this scenario, Northeast unemployment rises from 4.3% in the second quarter of 2025 to 5.8% by the end of the forecast period in the fourth quarter of 2026, with a peak Northeast unemployment rate of 8.1% in the third quarter of 2027. These scenarios and their respective weightings are evaluated at each measurement date and reflect management’s expectations as of June 30, 2025. Additional qualitative adjustments were made for factors not incorporated in the forecasts or the model, such as loss rate expectations for certain loan pools, reversion adjustments for the stagflation scenario and recent trends in asset value indices. Additional monitoring for industry concentrations, loan growth and policy exceptions was also conducted. The quantitative model as of December 31, 2024 incorporated a baseline economic outlook along with an alternative downside scenario sourced from a reputable third-party to accommodate other potential economic conditions in the model. At December 31, 2024, the weightings were 80% and 20% for the baseline and downside economic forecasts, respectively. The baseline outlook reflected a Northeast unemployment rate environment starting at 4.1% and increasing slightly during the forecast period to 4.2%. Northeast GDP’s annualized growth (on a quarterly basis) is expected to start the first quarter of 2025 at approximately 3.8% before decreasing to a low of 2.6% in the third quarter of 2025 and then increasing to 3.9% by the end of the forecast period. Key assumptions in the baseline economic outlook included two 25 basis point federal funds rate cuts in 2025, quantitative tightening ending in early 2025, a post-election fiscal outlook with lower spending, lower taxes, and higher tariffs, and the economy currently being near full employment. The alternative downside scenario assumed deteriorated economic conditions from the baseline outlook. Under this scenario, Northeast unemployment increases to a peak of 7.5% in the first quarter of 2026. These scenarios and their respective weightings are evaluated at each measurement date and reflect management’s expectations as of December 31, 2024. Additional qualitative adjustments were made for factors not incorporated in the forecasts or the model, such as loss rate expectations for certain loan pools, considerations for inflation and recent trends in asset value indices. Additional monitoring for industry concentrations, loan growth and policy exceptions was also conducted. 17 Table of Contents There were $ 336.4 million of PCD loans acquired from Evans during the nine months ended September 30, 2025 which resulted in an allowance for credit losses at acquisition of $ 7.7 million. There were no loans purchased with credit deterioration during the year ended December 31, 2024.

In addition, the allowance for credit losses increased due to deterioration in the economic forecast including the change in the forecast scenarios and weightings, partially offset by model refreshment and the shift in loan composition driven by other consumer and residential solar portfolios that are in a planned run-off status. The allowance for credit losses decreased slightly compared to the allowance estimates as of June 30, 2025 primarily due to a decrease in loan balances partially offset by the change in the forecast scenarios weightings. Individually Evaluated Loans The threshold for evaluating classified, Commercial & Industrial (“C&I”) and Commercial Real Estate (“CRE”) loans risk graded substandard or doubtful, and nonperforming loans specifically evaluated for individual credit loss is $ 1.0 million. As of September 30, 2025, seven relationships with an amortized cost basis of $ 16.0 million, including six acquired relationships from Evans, were identified for individual credit loss evaluation. These relationships were in nonaccrual status with no allowance for credit loss. As of December 31, 2024, three relationships were identified for individual credit loss evaluation, had an amortized cost basis of $ 28.8 millio n and were in nonaccrual status with no allowance for credit loss. The decrease in the amortized cost basis of individually evaluated loans from December 31, 2024 to September 30, 2025 was primarily attributed to the three relationships resolving through payoff or transfer to other assets in the second quarter of 2025, partially offset by the addition of the previously mentioned six acquired relationships from Evans which had an amortized cost basis of $ 13.9 million. 18 Table of Contents The following table sets forth information with regard to past due and nonperforming loans by loan segment: (In thousands) 31-60 Days Past Due Accruing 61-90 Days Past Due Accruing Greater Than 90 Days Past Due Accruing Total Past Due Accruing Nonaccrual Current Recorded Total Loans As of September 30 , 2025 Commercial loans: C&I $ 1,567 $ 1,134 $ - $ 2,701 $ 1,871 $ 1,614,656 $ 1,619,228 CRE 7,882 3 2,099 9,984 19,522 4,629,616 4,659,122 Total commercial loans $ 9,449 $ 1,137 $ 2,099 $ 12,685 $ 21,393 $ 6,244,272 $ 6,278,350 Consumer loans: Auto $ 11,293 $ 1,732 $ 870 $ 13,895 $ 2,272 $ 1,287,469 $ 1,303,636 Residential solar 3,717 1,196 1,093 6,006 195 751,781 757,982 Other consumer 1,165 495 381 2,041 172 86,060 88,273 Total consumer loans $ 16,175 $ 3,423 $ 2,344 $ 21,942 $ 2,639 $ 2,125,310 $ 2,149,891 Residential $ 6,426 $ 752 $ 2,523 $ 9,701 $ 22,418 $ 3,134,774 $ 3,166,893 Total loans $ 32,050 $ 5,312 $ 6,966 $ 44,328 $ 46,450 $ 11,504,356 $ 11,595,134 (In thousands) 31-60 Days Past Due Accruing 61-90 Days Past Due Accruing Greater Than 90 Days Past Due Accruing Total Past Due Accruing Nonaccrual Current Recorded Total Loans As of December 31, 2024 Commercial loans: C&I $ 398 $ 452 $ - $ 850 $ 2,116 $ 1,427,247 $ 1,430,213 CRE 698 191 - 889 30,028 3,665,223 3,696,140 Total commercial loans $ 1,096 $ 643 $ - $ 1,739 $ 32,144 $ 5,092,470 $ 5,126,353 Consumer loans: Auto $ 11,527 $ 2,047 $ 900 $ 14,474 $ 2,054 $ 1,228,378 $ 1,244,906 Residential solar 4,066 1,991 1,599 7,656 212 812,211 820,079 Other consumer 1,552 985 888 3,425 263 105,529 109,217 Total consumer loans $ 17,145 $ 5,023 $ 3,387 $ 25,555 $ 2,529 $ 2,146,118 $ 2,174,202 Residential $ 3,360 $ 467 $ 2,411 $ 6,238 $ 11,146 $ 2,651,971 $ 2,669,355 Total loans $ 21,601 $ 6,133 $ 5,798 $ 33,532 $ 45,819 $ 9,890,559 $ 9,969,910 Credit Quality Indicators The Company has developed an internal loan grading system to evaluate and quantify the Company’s loan portfolio with respect to quality and risk, focusing on, among other things, borrower’s financial strength, experience and depth of borrower’s management, primary and secondary sources of repayment, payment history, nature of the business and industry outlook. The internal grading system enables the Company to monitor the quality of the entire loan portfolio on a consistent basis and provide management with an early warning system, which facilitates recognition of and response to problem loans and potential problem loans. Commercial Grading System For C&I and CRE loans, the Company uses a grading system that relies on quantifiable and measurable characteristics when available. This includes comparison of financial strength to available industry averages, comparison of transaction factors (loan terms and conditions) to loan policy and comparison of credit history to stated repayment terms and industry averages. Some grading factors are necessarily more subjective such as economic and industry factors, regulatory environment and management. C&I and CRE loans are graded Doubtful, Substandard, Special Mention and Pass. Doubtful - A Doubtful loan has a high probability of total or substantial loss, but because of specific pending events that may strengthen the asset, its classification as a loss is deferred. Doubtful borrowers are usually in default, lack adequate liquidity or capital and lack the resources necessary to remain an operating entity. Pending events can include mergers, acquisitions, liquidations, capital injections, the perfection of liens on additional collateral, the valuation of collateral and refinancing. Generally, pending events should be resolved within a relatively short period and the ratings will be adjusted based on the new information. Nonaccrual treatment is required for Doubtful assets because of the high probability of loss. 19 Table of Contents Substandard - Substandard loans have a high probability of payment default or they have other well-defined weaknesses. They require more intensive supervision by bank management. Substandard loans are generally characterized by current or expected unprofitable operations, inadequate debt service coverage, inadequate liquidity or marginal capitalization. Repayment may depend on collateral or other credit risk mitigants. For some Substandard loans, the likelihood of full collection of interest and principal may be in doubt and those loans should be placed on nonaccrual. Although Substandard assets in the aggregate will have a distinct potential for loss, an individual asset’s loss potential does not have to be distinct for the asset to be rated Substandard. Special Mention - Special Mention loans have potential weaknesses that may, if not checked or corrected, weaken the asset or inadequately protect the Company’s position at some future date. These loans pose elevated risk, but their weakness does not yet justify a Substandard classification. Borrowers may be experiencing adverse operating trends (i.e., declining revenues or margins) or may be struggling with an ill-proportioned balance sheet (i.e., increasing inventory without an increase in sales, high leverage and/or tight liquidity). Adverse economic or market conditions, such as interest rate increases or the entry of a new competitor, may also support a Special Mention rating. Although a Special Mention loan has a higher PD than a Pass asset, its default is not imminent. Pass - Loans graded as Pass encompass all loans not graded as Doubtful, Substandard or Special Mention. Pass loans are in compliance with loan covenants and payments are generally made as agreed. Pass loans range from superior quality to fair quality. Pass loans also include any portion of a government guaranteed loan, including Paycheck Protection Program loans. Consumer and Residential Grading System Consumer and Residential loans are graded as either Nonperforming or Performing. Nonperforming - Nonperforming loans are loans that are (1) over 90 days past due and interest is still accruing or (2) on nonaccrual status. Performing - All loans not meeting any of the above criteria are considered Performing. The following tables illustrate the Company’s credit quality by loan class by vintage and includes gross charge-offs by loan class by vintage. Included in other consumer gross charge-offs for the nine months ended September 30, 2025, the Company recorded $ 0.3 million in overdrawn deposit accounts reported as 2024 originations and $ 0.5 million in overdrawn deposit accounts reported as 2025 originations. Included in other consumer gross charge-offs for the year ended December 31, 2024, the Company recorded $ 0.2 million in overdrawn deposit accounts reported as 2023 originations and $ 0.7 million in overdrawn deposit accounts reported as 2024 originations .

The reserve for unfunded loan commitments was $( 0.3 ) million for the three months ended September 30, 2025, compared to $ 0.3 million for the three months ended September 30, 2024 and was recorded within other noninterest expense in the unaudited interim consolidated statements of income. The reserve for unfunded loan commitments was $ 1.5 million for the nine months ended September 30, 2025, compared to $( 0.6 ) million for the nine months ended September 30, 2024, and was recorded within other noninterest expense in the unaudited interim consolidated statements of income. Included in the reserve for unfunded loan commitments for the nine months ended September 30, 2025, was $ 0.5 million of acquisition-related provision for unfunded loan commitments due to the Evans acquisition. The increase for the nine months ended September 30, 2025 is primarily related to increases in pipeline exposure and the Evans acquisition. Loan Modifications to Borrowers Experiencing Financial Difficulties When the Company modifies a loan with financial difficulty, such modifications generally include one or a combination of the following: an extension of the maturity date at a stated rate of interest lower than the current market rate for new debt with similar risk; a change in scheduled payment amount; or principal forgiveness. The following tables show the amortized cost basis at the end of the reporting period of the loans modified to borrowers experiencing financial difficulty, disaggregated by class of financing receivable and type of concession granted: Three Months Ended September 30, 2025 Term Extension (Dollars in thousands) Amortized Cost % of Total Class of Financing Receivables Residential $ 75 0.002 % Total $ 75 Three Months Ended September 30, 2024 Term Extension Combination - Term Extension and Interest Rate Reduction (Dollars in thousands) Amortized Cost % of Total Class of Financing Receivables Amortized Cost % of Total Class of Financing Receivables Residential $ 576 0.022 % $ 254 0.010 % Total $ 576 $ 254 Nine Months Ended September 30, 2025 Term Extension Combination - Term Extension and Interest Rate Reduction (Dollars in thousands) Amortized Cost % of Total Class of Financing Receivables Amortized Cost % of Total Class of Financing Receivables Residential $ 958 0.030 % $ 28 0.001 % Total $ 958 $ 28 Nine Months Ended September 30, 2024 Term Extension Combination - Term Extension and Interest Rate Reduction (Dollars in thousands) Amortized Cost % of Total Class of Financing Receivables Amortized Cost % of Total Class of Financing Receivables Residential $ 1,054 0.040 % $ 284 0.011 % Total $ 1,054 $ 284 22 Table of Contents The following tables describe the financial effect of the modifications made to borrowers experiencing financial difficulties: Three Months Ended September 30, 2025 Loan Type Term Extension Residential Added a weighted-average 1.6 years to the life of loans, which reduced monthly payment amounts for the borrowers Three Months Ended September 30, 2024 Loan Type Term Extension Interest Rate Reduction Residential Added a weighted-average 8.2 years to the life of loans, which reduced monthly payment amounts for the borrowers Interest Rates were reduced by an average of 0.25 % Nine Months Ended September 30, 2025 Loan Type Term Extension Interest Rate Reduction Residential Added a weighted-average 5.6 years to the life of loans, which reduced monthly payment amounts for the borrowers Interest Rates were reduced by an average of 0.62 % Nine Months Ended September 30, 2024 Loan Type Term Extension Interest Rate Reduction Residential Added a weighted-average 6.5 years to the life of loans, which reduced monthly payment amounts for the borrowers Interest Rates were reduced by an average of 0.63 % There were no financing receivables that had a payment default during the three months ended September 30, 2025 and 2024, that were modified to borrowers experiencing financial difficulty in the twelve months prior to the default.

Borrowings Short-Term Borrowings In addition to the liquidity provided by balance sheet cash flows, liquidity must also be supplemented with additional sources such as credit lines from correspondent banks as well as borrowings from the Federal Home Loan Bank (“FHLB”) and the Federal Reserve Bank. Other funding alternatives may also be appropriate from time to time, including wholesale and retail repurchase agreements and brokered certificate of deposit accounts. Information related to short-term borrowings is summarized as follows: (In thousands) September 30, 2025 December 31, 2024 Securities sold under repurchase agreements $ 138,729 $ 146,942 Other short-term borrowings - 16,000 Total short-term borrowings $ 138,729 $ 162,942 See Note 5 for additional information regarding securities pledged as collateral for securities sold under the repurchase agreements. Subordinated Debt On June 23, 2020, the Company issued $ 100.0 million aggregate principal amount of 5.00 % fixed-to-floating rate subordinated notes due 2030. The subordinated notes, which qualified as Tier 2 capital, bore interest at an annual rate of 5.00 %, payable semi-annually in arrears commencing on January 1, 2021, and a floating rate of interest equivalent to the three-month Secured Overnight Financing Rate (“ SOFR ”) plus a spread of 4.85 %, payable quarterly in arrears commencing on October 1, 2025. The subordinated notes issuance costs of $ 2.2 million were amortized on a straight-line basis into interest expense over five years . The subordinated notes were redeemable (1) in whole or in part beginning with the interest payment date of July 1, 2025, and on any interest payment date thereafter or (2) in whole but not in part upon the occurrence of a “Tax Event”, a “Tier 2 Capital Event” or in the event the Company was required to register as an investment company pursuant to the Investment Company Act of 1940, as amended. The redemption price for any redemption was 100 % of the principal amount of the subordinated notes being redeemed, plus accrued and unpaid interest thereon to, but excluding, the date of redemption. Any redemption of the subordinated notes was subject to the receipt of the approval of the Board of Governors of the Federal Reserve System to the extent required under applicable laws or regulations, including capital regulations. The Company repurchased $ 2.0 million of the subordinated notes during the year ended December 31, 2022 at a discount of $ 0.1 million. On July 1, 2025, the Company redeemed these subordinated notes in full using existing liquidity sources. The subordinated notes assumed in connection with the Salisbury acquisition included $ 25.0 million of 3.50 % fixed-to-floating rate subordinated notes due 2031. The subordinated notes, which qualified as Tier 2 capital, have a maturity date of March 31, 2031 and bore interest at an annual rate of 3.50 %, payable quarterly in arrears commencing on June 30, 2021, and a floating rate of interest equivalent to the three-month SOFR plus a spread of 2.80 %, payable quarterly in arrears commencing on June 30, 2026. The subordinated notes are redeemable, without penalty, on or after March 31, 2026 and, in certain limited circumstances, prior to that date. As of the acquisition date, the fair value discount was $ 3.0 million. Subordinated notes assumed in connection with the Evans acquisition included $ 20.0 million of 6.00 % fixed-to-floating rate subordinated notes due 2030. The subordinated notes, which qualified as Tier 2 capital, bore interest at an annual rate of 6.00 %, payable semi-annually in arrears commencing on January 15, 2021, and a floating rate of interest equivalent to the three-month SOFR plus a spread of 5.90 %, payable quarterly in arrears commencing on July 15, 2025. On July 15, 2025, the Company redeemed these subordinated notes in full using existing liquidity sources.

Defined Benefit Post-Retirement Plans The Company has a qualified, noncontributory, defined benefit pension plan (the “Plan”) covering substantially all of its employees at September 30, 2025. Benefits paid from the Plan are based on age, years of service, compensation and social security benefits and are determined in accordance with defined formulas. The Company’s policy is to fund the Plan in accordance with Employee Retirement Income Security Act of 1974 standards. Assets of the Plan are invested in publicly traded stocks, bonds and mutual funds. In addition to the Plan, the Company provides supplemental employee retirement plans to certain current and former executives. These supplemental employee retirement plans and the Plan are collectively referred to herein as “Pension Benefits.” In addition, the Company provides certain health care benefits for retired employees. Benefits were accrued over the employees’ active service period. Only employees that were employed by the Company on or before January 1, 2000 are eligible to receive post-retirement health care benefits. These post-retirement benefits are referred to herein as “Other Benefits.” In connection with the Evans acquisition, the Company assumed the non-contributory, qualified, defined benefit pension plan and the nonqualified supplemental executive retirement plans. Effective May 2, 2025, the Evans defined benefit pension plan was merged into the Plan. The merging of the plans required a valuation as of the merger date and resulted in a $ 0.9 million adjustment to AOCI. The merging of the plans did not have a significant impact on the Company’s financial statements and related footnotes. Accounting standards require an employer to: (1) recognize the overfunded or underfunded status of defined benefit post-retirement plans, which is measured as the difference between plan assets at fair value and the benefit obligation, as an asset or liability in its balance sheet; (2) recognize changes in that funded status in the year in which the changes occur through comprehensive income; and (3) measure the defined benefit plan assets and obligations as of the date of its year-end balance sheet. The Company made no voluntary contributions to the Pension Benefits and Other Benefits plans during the three and nine months ended September 30, 2025 and 2024. The components of expense for Pension Benefits and Other Benefits are set forth below: Pension Benefits Other Benefits Three Months Ended September 30, Three Months Ended September 30, (In thousands) 2025 2024 2025 2024 Components of net periodic cost (benefit): Service cost $ 696 $ 552 $ 1 $ 1 Interest cost 1,231 1,007 59 58 Expected return on plan assets ( 2,142 ) ( 1,972 ) - - Net amortization 276 472 ( 1 ) ( 1 ) Total net periodic cost (benefit) $ 61 $ 59 $ 59 $ 58 Pension Benefits Other Benefits Nine Months Ended September 30, Nine Months Ended September 30, (In thousands) 2025 2024 2025 2024 Components of net periodic cost (benefit): Service cost $ 2,065 $ 1,579 $ 3 $ 3 Interest cost 3,437 3,018 177 168 Expected return on plan assets ( 6,278 ) ( 5,937 ) - - Net amortization 909 2,377 ( 3 ) ( 3 ) Total net periodic cost (benefit) $ 133 $ 1,037 $ 177 $ 168 The service cost component of the net periodic cost (benefit) is included in salaries and employee benefits and the interest cost, expected return on plan assets and net amortization components are included in other noninterest expense on the unaudited interim consolidated statements of income. 25 Table of Contents 10. Earnings Per Share Basic earnings per share (“EPS”) excludes dilution and is computed by dividing income available to common stockholders by the weighted average number of common shares outstanding for the period. Diluted EPS reflects the potential dilution that could occur if securities or other contracts to issue common stock were exercised or converted into common stock or resulted in the issuance of common stock that then shared in the earnings of the entity (such as the Company’s dilutive restricted stock units and stock options). The following is a reconciliation of basic and diluted EPS for the periods presented in the unaudited interim consolidated statements of income: Three Months Ended September 30, (In thousands, except per share data) 2025 2024 Basic EPS: Weighted average common shares outstanding 52,426 47,172 Net income available to common stockholders $ 54,471 $ 38,097 Basic EPS $ 1.04 $ 0.81 Diluted EPS: Weighted average common shares outstanding 52,426 47,172 Dilutive effect of common stock options and restricted stock 217 301 Weighted average common shares and common share equivalents 52,643 47,473 Net income available to common stockholders $ 54,471 $ 38,097 Diluted EPS $ 1.03 $ 0.80 Nine Months Ended September 30, (In thousands, except per share data) 2025 2024 Basic EPS: Weighted average common shares outstanding 50,100 47,159 Net income available to common stockholders $ 113,726 $ 104,636 Basic EPS $ 2.27 $ 2.22 Diluted EPS: Weighted average common shares outstanding 50,100 47,159 Dilutive effect of common stock options and restricted stock 226 251 Weighted average common shares and common share equivalents 50,326 47,410 Net income available to common stockholders $ 113,726 $ 104,636 Diluted EPS $ 2.26 $ 2.21 There was a nominal number of anti-dilutive stock options and restricted stock outstanding for the nine months ended September 30, 2024, that were not considered in the calculation of diluted EPS. 26 Table of Contents 11.

Derivative Instruments and Hedging Activities The Company is exposed to certain risks arising from both its business operations and economic conditions. The Company principally manages its exposures to a wide variety of business and operational risks through management of its core business activities. The Company manages economic risks, including interest rate risk, primarily by managing the amount, sources and duration of its assets and liabilities and through the use of derivative instruments. Specifically, the Company may enter into derivative financial instruments to manage exposures that arise from business activities that result in the receipt or payment of future known and uncertain cash amounts, the value of which is determined by interest rates. Generally, the Company may use derivative financial instruments to manage differences in the amount, timing and duration of the Company’s known or expected cash receipts and its known or expected cash payments. Currently, the Company has interest rate derivatives resulting from a service provided to certain qualifying customers and, therefore, are not used to manage interest rate risk in the Company’s assets or liabilities. The Company manages a matched book with respect to its derivative instruments in order to minimize its net risk exposure resulting from such transactions. 27 Table of Contents Derivatives Not Designated as Hedging Instruments The Company enters into interest rate swaps to facilitate customer transactions and meet their financing needs. These swaps are considered derivatives, but are not designated as hedging relationships. These instruments have interest rate and credit risk associated with them. To mitigate the interest rate risk, the Company enters into offsetting interest rate swaps with counterparties. The counterparty swaps are also considered derivatives and are also not designated as hedging relationships. Interest rate swaps are recorded within other assets or other liabilities on the consolidated balance sheets at their estimated fair value. Changes to the fair value of assets and liabilities arising from these derivatives are included, net, in other operating income in the consolidated statements of incom e. The Company is subject to over-the-counter derivative clearing requirements, which require certain derivatives to be cleared through central clearing houses. Accordingly, the Company clears certain derivative transactions through the Chicago Mercantile Exchange Clearing House (“CME”). The CME requires the Company to post initial and variation margin payments to mitigate the risk of non-payment, the latter of which is received or paid daily based on the net asset or liability position of the contracts. A daily settlement occurs through the CME for changes in the fair value of centrally cleared derivatives. Not all of the derivatives are required to be cleared through the daily clearing agent. As a result, the total fair values of loan level derivative assets and liabilities recognized on the Company’s financial statements are not equal and offsetting. As of September 30, 2025 and December 31, 2024, the Company had twenty-two and twenty participation agreements, respectively, with financial institution counterparties for interest rate swaps related to participated loans. Risk participation agreements provide credit protection to the financial institution that originated the swap transaction should the borrower fail to perform on its obligation. The Company enters into both risk participation agreements in which it purchases credit protection from other financial institutions and those in which it provides credit protection to other financial institutions. T he following table summarizes the derivatives outstanding: (In thousands) Notional Amount Balance Sheet Location Fair Value Notional Amount Balance Sheet Location Fair Value As of September 30 , 2025 Derivatives not designated as hedging instruments Interest rate derivatives $ 1,333,167 Other assets $ 70,322 $ 1,333,167 Other liabilities $ 70,220 Risk participation agreements 97,796 Other assets 71 16,391 Other liabilities 25 Total derivatives not designated as hedging instruments $ 70,393 $ 70,245 Netting adjustments (1) 16,136 - Net derivatives in the balance sheet $ 54,257 $ 70,245 Derivatives not offset on the balance sheet $ 6,556 $ 6,556 Cash collateral (2) - - Net derivative amounts $ 47,701 $ 63,689 As of December 31, 2024 Derivatives not designated as hedging instruments Interest rate derivatives $ 1,374,800 Other assets $ 104,377 $ 1,374,800 Other liabilities $ 104,371 Risk participation agreements 90,725 Other assets 62 18,811 Other liabilities 2 Total derivatives not designated as hedging instruments $ 104,439 $ 104,373 Netting adjustments (1) 23,592 ( 26 ) Net derivatives in the balance sheet $ 80,847 $ 104,399 Derivatives not offset on the balance sheet $ 1,792 $ 1,792 Cash collateral (2) - - Net derivative amounts $ 79,055 $ 102,607 (1) Netting adjustments represent the amounts recorded to convert derivative assets and liabilities from a gross basis to a net basis in accordance with the applicable accounting guidance on the settle to market rules for cleared derivatives. The CME legally characterizes the variation margin posted between counterparties as settlements of the outstanding derivative contracts instead of cash collateral . (2) Cash collateral represents the amount that cannot be used to offset our derivative assets and liabilities from a gross basis to a net basis in accordance with the applicable accounting guidance. The other collateral consists of securities and is exchanged under bilateral collateral and master netting agreements that allow us to offset the net derivative position with the related collateral. The application of the other collateral cannot reduce the net derivative position below zero. Therefore, excess other collateral, if any, is not reflected above. 28 Table of Contents The following table indicates the gain or loss recognized in income on derivatives not designated as a hedging relationship: Three Months Ended September 30, Nine Months Ended September 30, (In thousands) 2025 2024 2025 2024 Derivatives not designated as hedging instruments: Increase in other income $ 161 $ 65 $ 178 $ 151 13. Fair Value Measurements and Fair Value of Financial Instruments G AAP states that fair value is an exit price, representing the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants. Fair value measurements are not adjusted for transaction costs. A fair value hierarchy exists within GAAP that prioritizes the inputs to valuation techniques used to measure fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurements) and the lowest priority to unobservable inputs (Level 3 measurements). The three levels of the fair value hierarchy are described below: Level 1 - Unadjusted quoted prices in active markets that are accessible at the measurement date for identical, unrestricted assets or liabilities; Level 2 - Quoted prices for similar assets or liabilities in active markets, quoted prices in markets that are not active or inputs that are observable, either directly or indirectly, for substantially the full term of the asset or liability; and Level 3 - Prices or valuation techniques that require inputs that are both significant to the fair value measurement and unobservable (i.e., supported by little or no market activity). A financial instrument’s level within the fair value hierarchy is based on the lowest level of input that is significant to the fair value measurement. The types of instruments valued based on quoted market prices in active markets include most U.S. government and agency securities, many other sovereign government obligations, liquid mortgage products, active listed equities and most money market securities. Such instruments are generally classified within Level 1 or Level 2 of the fair value hierarchy. The Company does not adjust the quoted prices for such instruments. The types of instruments valued based on quoted prices in markets that are not active, broker or dealer quotations or quotes from alternative pricing sources with reasonable levels of price transparency include most investment-grade and high-yield corporate bonds, less liquid mortgage products, less liquid agency securities, less liquid listed equities, state, municipal and provincial obligations and certain physical commodities. Such instruments are generally classified within Level 2 of the fair value hierarchy. Certain common equity securities are reported at fair value utilizing Level 1 inputs (exchange quoted prices). Other investment securities are reported at fair value utilizing Level 1 and Level 2 inputs. The prices for Level 2 instruments are obtained through an independent pricing service or dealer market participants with whom the Company has historically transacted both purchases and sales of investment securities. Prices obtained from these sources include prices derived from market quotations and matrix pricing. The fair value measurements consider observable data that may include dealer quotes, market spreads, cash flows, the U.S. Treasury yield curve, live trading levels, trade execution data, market consensus prepayment speeds, credit information and the bond’s terms and conditions, among other things. Management reviews the methodologies used by its third-party providers in pricing the securities. Level 3 is for positions that are not traded in active markets or are subject to transfer restrictions. Valuations are adjusted to reflect illiquidity and/or non-transferability and such adjustments are generally based on available market evidence. In the absence of such evidence, management’s best estimate will be used. Management’s best estimate consists of both internal and external support on certain Level 3 investments. Subsequent to inception, management only changes Level 3 inputs and assumptions when corroborated by evidence such as transactions in similar instruments, completed or pending third-party transactions in the underlying investment or comparable entities, subsequent rounds of financing, recapitalizations and other transactions across the capital structure, offerings in the equity or debt markets and changes in financial ratios or cash flow s. 29 Table of Contents The following tables set forth the Company’s financial assets and liabilities measured on a recurring basis that were accounted for at fair value. Assets and liabilities are classified in their entirety based on the lowest level of input that is significant to the fair value measurement: (In thousands) Level 1 Level 2 Level 3 September 30, 2025 Assets: AFS securities: U.S. treasury $ 101,080 $ - $ - $ 101,080 Federal agency - 229,056 - 229,056 State & municipal - 88,697 - 88,697 Mortgage-backed - 565,303 - 565,303 Collateralized mortgage obligations - 797,106 - 797,106 Corporate - 31,952 - 31,952 Total AFS securities $ 101,080 $ 1,712,114 $ - $ 1,813,194 Equity securities 48,607 1,000 - 49,607 Derivatives - 54,257 - 54,257 Total $ 149,687 $ 1,767,371 $ - $ 1,917,058 Liabilities: Derivatives $ - $ 70,245 $ - $ 70,245 Total $ - $ 70,245 $ - $ 70,245 (In thousands) Level 1 Level 2 Level 3 December 31, 2024 Assets: AFS securities: U.S. treasury $ 102,790 $ - $ - $ 102,790 Federal agency - 218,517 - 218,517 State & municipal - 87,490 - 87,490 Mortgage-backed - 464,365 - 464,365 Collateralized mortgage obligations - 656,488 - 656,488 Corporate - 45,014 - 45,014 Total AFS securities $ 102,790 $ 1,471,874 $ - $ 1,574,664 Equity securities 41,372 1,000 - 42,372 Derivatives - 80,847 - 80,847 Total $ 144,162 $ 1,553,721 $ - $ 1,697,883 Liabilities: Derivatives $ - $ 104,399 $ - $ 104,399 Total $ - $ 104,399 $ - $ 104,399 GAAP requires disclosure of assets and liabilities measured and recorded at fair value on a non-recurring basis such as goodwill, loans held for sale, other real estate owned, collateral-dependent loans individually evaluated for expected credit losses and HTM securities. Loans with fair value of $ 16.0 million as of September 30, 2025 were individually evaluated for expected credit losses where the amortized cost was adjusted to fair value. Loans with fair value of $ 28.8 million as of December 31, 2024 were individually evaluated for expected credit losses where the amortized cost was adjusted to fair value. The Company uses the fair value of underlying collateral, less costs to sell, to estimate the allowance for credit losses for individually evaluated collateral dependent loans. The appraisals may be adjusted by management for qualitative factors such as economic conditions and estimated liquidation expenses ranging from 10 % to 50 % . Based on the valuation techniques used, the fair value measurements for collateral dependent individually evaluated loans are classified as Level 3. The following table sets forth information with regard to estimated fair values of financial instruments. This table excludes financial instruments for which the carrying amount approximates fair value. Financial instruments for which the fair value approximates carrying value include cash and cash equivalents, AFS securities, equity securities, AIR, non-maturity deposits, short-term borrowings, accrued interest payable and derivatives.

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 financial 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 of significant judgment and therefore cannot be determined with precision. Changes in assumptions could significantly affect the estimates. Fair value estimates are based on existing 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. For example, the Company has a substantial wealth operation that contributes net fee income annually. The wealth management operation is not considered a financial instrument and its value has not been incorporated into the fair value estimates. Other significant assets and liabilities include the benefits resulting from the low-cost funding of deposit liabilities as compared to the cost of borrowing funds in the market and 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 estimate of fair value. HTM Securities - The fair value of the Company’s HTM securities is primarily measured using information from a third-party pricing service. The fair value measurements consider observable data that may include dealer quotes, market spreads, cash flows, the U.S. Treasury yield curve, live trading levels, trade execution data, market consensus prepayment speeds, credit information and the bond’s terms and conditions, among other things. Net Loans - Net loans include portfolio loans and loans held for sale. Loans were first segregated by type and then further segmented into fixed and variable rate and loan quality categories. Expected future cash flows were projected based on contractual cash flows, adjusted for estimated prepayments, and those expected future cash flows also includes credit risk, illiquidity risk and other market factors to calculate the exit price fair value in accordance with ASC 820. Time Deposits - The fair value of time deposits was estimated using a discounted cash flow approach that applies prevailing market interest rates for similar maturity instruments. The fair values of the Company’s time deposit liabilities do not take into consideration the value of the Company’s long-term relationships with depositors, which may have significant value. Long-Term Debt - The fair value of long-term debt was estimated using a discounted cash flow approach that applies prevailing market interest rates for similar maturity instruments. Subordinated Debt - The fair value of subordinated debt has been measured using the observable market price as of the period reported. Junior Subordinated Debt - The fair value of junior subordinated debt has been estimated using a discounted cash flow analysis. 14. Commitments and Contingencies The Company is a party to certain financial instruments with off-balance sheet risk in the normal course of business to meet the financing needs of its customers. These financial instruments include commitments to extend credit, unused lines of credit, standby letters of credit and certain agricultural real estate loans sold to investors with recourse, with the sold portion having a government guarantee that is assignable back to the Company upon repurchase of the loan in the event of default. The Company’s exposure to credit loss in the event of nonperformance by the other party to the commitments to extend credit, unused lines of credit, standby letters of credit and loans sold with recourse is represented by the contractual amount of those instruments. The credit risk associated with commitments to extend credit and standby and commercial letters of credit is essentially the same as that involved with extending loans to customers and is subject to normal credit policies. Collateral may be obtained based on management’s assessment of the customer’s creditworthiness. Commitments to extend credit and unused lines of credit totaled $ 3.28 billion at September 30, 2025 and $ 2.84 billion at December 31, 2024. Since many loan commitments, standby letters of credit and guarantees and indemnification contracts expire without being funded in whole or in part, the contract amounts are not necessarily indicative of future cash flows. The Company does not issue any guarantees that would require liability-recognition or disclosure, other than its standby letters of credit. The Company guarantees the obligations or performance of customers by issuing standby letters of credit to third-parties. These standby letters of credit are generally issued in support of third-party debt, such as corporate debt issuances, industrial revenue bonds and municipal securities. The risk involved in issuing standby letters of credit is essentially the same as the credit risk involved in extending loan facilities to customers and letters of credit are subject to the same credit origination, portfolio maintenance and management procedures in effect to monitor other credit and off-balance sheet products. Typically, these instruments have one year expirations with an option to renew upon annual review; therefore, the total amounts do not necessarily represent future cash requirements. Standby letters of credit totaled $ 61.2 million at September 30, 2025 and $ 50.8 million at December 31, 2024. A s of September 30, 2025 and December 31, 2024 , the fair value of the Company’s standby letters of credit was not significant. In the normal course of business there are various outstanding legal proceedings. The Company accrues for material estimated losses from loss contingencies if the information available indicates that it is probable that a liability had been incurred at the date of the financial statements and the amount of loss can be reasonably estimated. 31 Table of Contents 15. Segment Reporting Historically, the Company has operated as a single reportable segment, providing a full range of banking services to retail and commercial customers. However, in accordance with ASU 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures , and as the Bank has grown, management reassessed its operating segment structure to enhance transparency in how financial performance is evaluated and resources are allocated by the chief operating decision maker (“CODM”). The updated guidance enhances disclosures by requiring more detailed information on segment profitability and certain key performance metrics used by management. Segments are components of an enterprise that are regularly evaluated by the CODM to allocate resources and assess performance. The Company’s CODM is its Chief Executive Officer. As a result of this reassessment, beginning with the fiscal year ended December 31, 2024, the Company has determined that it now operates through two reportable segments: Banking - Provides commercial banking, retail banking, and wealth management services primarily to customers in its market area, offering a broad array of banking and financial services to retail, commercial, and municipal customers. Included in Banking are the revenue and expenses from the wealth management business and the parent holding company. The parent company’s principal activities include the direct and indirect ownership of banking and non-banking subsidiaries, as well as the issuance of debt and equity. The parent company’s principal sources of revenue are the management fees and dividends it receives from its subsidiaries. Banking also includes corporate shared service costs such as the majority of equity compensation expense, as well as other general and administrative shared services costs including pension, retirement plan and supplemental retirement plan costs. Currently there is no allocation of these costs to other operating segments. Retirement Plan Administration - Includes retirement plan and health savings account recordkeeping and administration, investment management, third-party administration, and actuarial services. Our CODM reviews actual net income versus budgeted net income to assess segment performance and to make decisions about allocating capital and personnel to the segments. The CODM regularly receives expense information at a level consistent with that disclosed in the Company’s consolidated statements of income. Reported segments and their financial information are not necessarily comparable to similar information reported by other financial institutions. Additionally, due to interrelationships among the various segments, the information presented is not indicative of how the segments would perform as independent entities. Changes in management structure, allocation methodologies, or procedures may result in future revisions to previously reported segment financial data. For the three and nine months ended September 30, 2024, the Company only disclosed one reportable segment, as operations were assessed on a consolidated basis. Accordingly, prior year segment data has been retrospectively adjusted to conform to the current period presentation. The Company will continue to evaluate its segment disclosures in accordance with ASU 2023-07 and make necessary adjustments as business operations evolve. Information about reportable segments and reconciliation of the information to the consolidated financial statements follows: Three Months Ended September 30, 2025 (In thousands) Banking Retirement Plan Administration All Other (1) Consolidated Net interest income $ 134,643 $ 20 $ -
