Notes to Unaudited Consolidated Financial Statements Note 1 – Corporate Structure and Nature of Operations; Basis of Presentation NB Bancorp, Inc., a Maryland corporation (the “Company”) (referred to herein as the “Company,” “we,” “us,” or “our”), is a bank holding company. Through its wholly-owned subsidiary, Needham Bank (the “Bank”), the Company provides a variety of banking services, through its full-service bank branches, located primarily in eastern Massachusetts. ​ The activities of the Company are subject to the regulatory supervision of the Board of Governors of the Federal Reserve System. The activities of the Bank are subject to the regulatory supervision of the Massachusetts Commissioner of Banks and the Federal Deposit Insurance Corporation (“FDIC”). The Company and the activities of the Bank and its subsidiaries are also subject to various Massachusetts business and banking-related regulations. ​ On June 5, 2025, the Company announced the signing of a definitive merger agreement under which the Company will acquire Provident Bancorp, Inc., with the Company as the surviving entity, and the Bank will acquire BankProv, the wholly owned subsidiary of Provident Bancorp, Inc., with the Bank as the surviving entity (the “Merger”). The transaction is valued at approximately $ 211.8 million. The closing of the Merger, which is expected to occur during the fourth quarter of 2025, was approved by the affirmative vote of the holders of a majority of Provident Bancorp, Inc. common stock and the receipt of required regulatory approvals from applicable state and federal regulators. ​ Basis of Presentation ​ The Company’s Consolidated Financial Statements have been prepared in conformity with accounting principles generally accepted in the United States (“U.S. GAAP”) as set forth by the Financial Accounting Standards Board (“FASB”) and its Accounting Standards Codification (“ASC”) and Accounting Standards Updates (“ASU”) as well as the rules and interpretive releases of the U.S. Securities and Exchange Commission (“SEC”) under the authority of federal securities laws. ​ The Consolidated Financial Statements of the Company include the balances and results of operations of the Company and the Bank, its wholly-owned subsidiary, as well as the Bank’s wholly-owned subsidiaries, NeedCo-op Investment Corporation, Inc., 1892 Investments LLC and Eaton Square Realty LLC. All intercompany accounts and transactions have been eliminated in consolidation. ​ Certain amounts, previously reported, have been reclassified to state all periods on a comparable basis and had no effect on shareholders’ equity or net income. ​ The accompanying Consolidated Balance Sheet as of September 30, 2025, the Consolidated Statements of Income, Consolidated Statements of Comprehensive Income, Consolidated Statements of Changes in Shareholders’ Equity and Consolidated Statements of Cash Flows for the three and nine months ended September 30, 2025 and 2024 are unaudited. The Consolidated Balance Sheet as of December 31, 2024 was derived from the Audited Consolidated Financial Statements as of that date. The interim Consolidated Financial Statements and the accompanying notes should be read in conjunction with the annual Consolidated Financial Statements and the accompanying notes contained within the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2024, as filed with the SEC. In the opinion of management, the Company’s Consolidated Financial Statements reflect all adjustments, which include only normal recurring adjustments, necessary for a fair statement of the results of operations for the periods presented. The results for the three and nine months ended September 30, 2025 are not necessarily indicative of results to be expected for the year ending December 31, 2025, any other interim period, or any future year or period. ​ 6 Table of Contents The Company qualifies as an emerging growth company (“EGC”) under the Jumpstart Our Business Startups Act of 2012 and has elected to defer the adoption of new or revised accounting standards until the nonpublic company effective dates. As such, the Company will adopt standards on the nonpublic company effective dates until such time that we no longer qualify as an EGC. Subsequent events are events or transactions that occur after the consolidated balance sheet date but before consolidated financial statements are issued. Recognized subsequent events are events or transactions that provide additional evidence about conditions that existed at the date of the consolidated balance sheet, including the estimates inherent in the process of preparing consolidated financial statements. Non-recognized subsequent events are events that provide evidence about conditions that did not exist at the date of the consolidated balance sheet but arose after that date. Operating Segments The Company adopted FASB ASU 2023-07 “Segment Reporting (Topic 280) - Improvement to Reportable Segment Disclosures” on January 1, 2024, which requires that information be reported about a company’s operating segments using a “management approach.” Reportable segments are identified in these standards as those revenue producing components for which separate financial information is produced internally and which are subject to evaluation by the chief operating decision maker (“CODM”). The Company has determined that its CODM is its Chief Executive Officer. The Company has one reportable segment: its banking business, which consists of a full range of banking, lending, savings, and small business offerings. The CODM regularly assesses performance of the aggregated single operating and reporting segment and decides how to allocate resources based on net income calculated on the same basis as is net income reported in the Company’s consolidated statements of income and other comprehensive income. The CODM is also regularly provided with expense information at a level consistent with that disclosed in the Company’s consolidated statements of income and other comprehensive income. ​ Note 2 – Summary of Significant Accounting Policies Use of Estimates ​ In preparing the Consolidated Financial Statements in conformity with U.S. GAAP, management is required to make estimates and assumptions that affect the reported amounts of assets and liabilities as of the date of the consolidated balance sheets and income and expenses for the periods reported. Actual results could differ from those estimates based on changing conditions, including economic conditions and future events. Material estimates that are particularly susceptible to change relate to the determination of the allowance for credit losses, valuation and fair value measurements, the liabilities for benefit obligations (particularly pensions) and the provision for income taxes. ​ Recent Accounting Pronouncements ​ Relevant standards that were recently issued but not yet adopted as of September 30, 2025: ​ In November 2024, the FASB issued ASU 2024-03, “ Income Statement – Reporting Comprehensive Income – Expense Disaggregation Disclosures (Sub Topic 220-40): Disaggregation of Income Statement Expenses ”. ASU 2024-03 improves disclosures about a public business entity’s expenses and addresses requests from investors for more detailed information about the types of expenses (including purchases of inventory, employee compensation, depreciation, amortization, and depletion) in commonly presented expense captions (such as cost of sales, SG&A, and research and development). ASU 2024-03 is effective for annual reporting periods beginning after December 15, 2026 and interim reporting periods beginning after December 15, 2027. Early adoption is permitted. The adoption of ASU 2024-03 is not expected to have a material impact on the Company’s consolidated financial statements. In December 2023, the FASB issued ASU 2023-09, “ Income Taxes (Topic 740): Improvements to Income Tax Disclosures” to improve the transparency of income tax disclosures. The amendments are effective for annual periods beginning after December 15, 2024. 7 Table of Contents Early adoption is permitted for annual financial statements that have not yet been issued or made available for issuance. The Company does not expect the adoption of ASU 2023-09 to have a material effect on its consolidated financial statements. Other accounting standards that have been issued or proposed by the FASB or other standard-setting bodies are not expected to have a material impact on the Company’s financial position, results of operations or cash flows. ​ Note 3 – Securities ​ The Company's available-for-sale securities are carried at fair value. For available-for-sale securities in an unrealized loss position, management will first evaluate whether there is intent to sell, or if it is more likely than not that the Company will be required to sell a security prior to anticipated recovery of its amortized cost basis. If either of these criteria are met, the Company will record a write-down of the security's amortized cost basis to fair value through income. For those available-for-sale securities which do not meet the intent or requirement to sell criteria, management will evaluate whether the decline in fair value is a result of credit-related matters or other factors. In performing this assessment, management considers the creditworthiness of the issuer including whether the security is guaranteed by the U.S. Federal Government or other government agency, the extent to which fair value is less than amortized cost, and changes in credit rating during the period, among other factors. ​ If this assessment indicates the existence of credit losses, the security will be written down to fair value, as determined by a discounted cash flow analysis, through an allowance for credit losses. To the extent the estimated cash flows do not support the amortized cost, the deficiency is considered to be due to credit loss and is recognized in earnings. ​ Changes in the allowance for credit losses are recorded as a provision for (or reversal of) credit loss expense. Losses are charged against the allowance when the uncollectibility of a security is confirmed, or when either of the aforementioned criteria surrounding intent or requirement to sell have been met. ​ Securities have been classified on the consolidated balance sheets according to management’s intent. The following tables summarize the amortized cost, allowance for credit losses, and fair value of securities and their corresponding amounts of unrealized gains and losses at the dates indicated: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Amortized ​ Unrealized ​ Unrealized ​ Allowance for ​ ​ ​ ​ Cost Gain Loss ​ Credit Losses Fair Value September 30, 2025 ​ (in thousands) Available-for-Sale Debt Securities: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ U.S. Treasury securities ​ $ 68,838 ​ $ 338 ​ $ ( 153 ) ​ $ — ​ $ 69,023 U.S. Government agencies ​ ​ 11,149 ​ ​ 52 ​ ​ ( 1 ) ​ ​ — ​ ​ 11,200 Agency mortgage-backed securities ​ ​ 45,043 ​ ​ 124 ​ ​ ( 1,320 ) ​ ​ — ​ ​ 43,847 Agency collateralized mortgage obligations ​ ​ 10,833 ​ ​ 224 ​ ​ ( 107 ) ​ ​ — ​ ​ 10,950 Corporate bonds ​ ​ 86,465 ​ ​ 272 ​ ​ ( 4,093 ) ​ ​ — ​ ​ 82,644 Municipal obligations ​ ​ 6,595 ​ ​ — ​ ​ ( 107 ) ​ ​ — ​ ​ 6,488 SBA securities ​ ​ 6,977 ​ ​ — ​ ​ ( 106 ) ​ ​ — ​ ​ 6,871 Total ​ $ 235,900 ​ $ 1,010 ​ $ ( 5,887 ) ​ $ — ​ $ 231,023 ​ 8 Table of Contents ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Amortized ​ Unrealized ​ Unrealized ​ Allowance for ​ ​ ​ ​ Cost Gain Loss ​ Credit Losses Fair Value December 31, 2024 ​ (in thousands) Available-for-Sale Debt Securities: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ U.S. Treasury securities ​ $ 69,469 ​ $ 104 ​ $ ( 489 ) ​ $ — ​ $ 69,084 U.S. Government agencies ​ ​ 9,005 ​ ​ 9 ​ ​ ( 7 ) ​ ​ — ​ ​ 9,007 Agency mortgage-backed securities ​ ​ 42,083 ​ ​ — ​ ​ ( 2,899 ) ​ ​ — ​ ​ 39,184 Agency collateralized mortgage obligations ​ ​ 10,993 ​ ​ 147 ​ ​ ( 307 ) ​ ​ — ​ ​ 10,833 Corporate bonds ​ ​ 90,219 ​ ​ 163 ​ ​ ( 6,337 ) ​ ​ — ​ ​ 84,045 Municipal obligations ​ ​ 10,092 ​ ​ — ​ ​ ( 286 ) ​ ​ — ​ ​ 9,806 SBA securities ​ ​ 6,298 ​ ​ 2 ​ ​ ( 54 ) ​ ​ — ​ ​ 6,246 Total ​ $ 238,159 ​ $ 425 ​ $ ( 10,379 ) ​ $ — ​ $ 228,205 ​ The Company did not record a provision for estimated credit losses on any available-for-sale securities for the three and nine months ended September 30, 2025 and 2024.

These unrealized losses relate to changes in market interest rates since acquiring the securities. As management has the intent and ability to hold available-for-sale debt securities until maturity or cost recovery, no allowance for credit losses on securities is deemed necessary as of September 30, 2025 and December 31, 2024. ​ Note 4 – Loans Receivable, Allowance for Credit Losses and Credit Quality Loans Receivable ​ Loans that management has the intent and ability to hold for the foreseeable future or until maturity or pay-off are reported as held-for-investment at their outstanding principal balance adjusted for any charge-offs and net of any deferred fees (including purchase accounting adjustments) and origination costs (collectively referred to as “amortized cost”). For originated loans, loan fees and certain direct origination costs are deferred and amortized or accreted into interest income over the contractual life of the loan using the level-yield method. When a loan is paid off, the unamortized portion is recognized in interest income. ​ Loans are generally placed into nonaccrual status when they are past due 90 days or more as to either principal or interest or when, in the opinion of management, the collection of principal and/or interest is in doubt. A loan remains in nonaccrual status until the loan is current as to payment of both principal and interest or past due less than 90 days and the borrower demonstrates the ability to pay and remain current. 10 Table of Contents When cash payments are received, they are applied to principal first, then to accrued interest. It is the Company’s policy not to record interest income on nonaccrual loans until principal has become current and the borrower demonstrated the ability to pay and remain current. In certain instances, accruing loans that are past due 90 days or more as to principal or interest may not go on nonaccrual status if the Company determines that the loans are well-secured and are in the process of collection. ​ Allowance for Credit Losses ​ The Allowance for Credit Losses (“ACL”) represents management’s best estimate of credit losses over the remaining life of the loan portfolio. Loans are charged-off against the ACL when management believes the loan balance is no longer collectible. This determination made is based on management's review of specific facts and circumstances of the individual loan, including the expected cash flows to repay the loan, the value of the collateral and the ability and willingness of any guarantors to perform. Subsequent recoveries of previously charged-off amounts are recorded as increases to the ACL. The provision for credit losses on loans is an amount sufficient to bring the ACL to an estimated balance that management considers adequate to absorb lifetime expected losses in the Company’s held-for-investment loan portfolio. The ACL is a valuation account that is deducted from the loans’ amortized cost basis to present the net amount expected to be collected on the loans. Management’s determination of the adequacy of the ACL under Financial Accounting Standards Board (“ FASB”) Accounting Standards Codification (“ASC”) 326 – Financial Instruments – Credit Losses is based on an evaluation of the composition of the loan portfolio, current economic conditions, historical loan loss experience, reasonable and supportable forecasts, and other risk factors. The Company uses a third-party Current Expected Credit Loss (“CECL”) model as part of its estimation of the ACL on a quarterly basis. Loans with similar risk characteristics are collectively assessed within pools (or segments). Loss estimates within the collectively assessed population are based on a combination of pooled assumptions and loan-level characteristics. The Company has determined that using federal call codes is an appropriate loan segmentation methodology, as it is generally based on risk characteristics of a loan’s underlying collateral. Using federal call codes also allows the Company to utilize and assess publicly available external information when developing its estimate of the ACL. ​ The weighted average remaining maturity (“WARM”) method is the primary credit loss estimation methodology used by the Company and involves estimating future cash flows and expected credit losses for pools of loans using their expected remaining weighted average life. ​ In applying future economic forecasts, the Company utilizes a forecast period of up to two years. Historical loss rates used in the quantitative model are primarily derived using both the Bank’s data, supplemented with peer bank data obtained from publicly available sources. Management also considers qualitative adjustments when estimating credit losses in consideration of the model’s quantitative limitations. Qualitative adjustments to quantitative loss factors, either negative or positive, may include considerations of economic conditions, volume and severity of past due loans, value of underlying collateral, experience, depth, and ability of management, and concentrations of credit. During the three and nine months ended September 30, 2025, as part of management’s annual analysis of prepayment speeds, the historical prepayment speed analysis of the purchased consumer loans portfolio used in the ACL calculation was enhanced, transitioning from a lifetime analysis to a month-over-month analysis. The resulting Other Consumer loans prepayment speed forecast dropped from 16.8 % to 10.1 % and resulted in a $ 1.3 million increase in the quantitative value of the Other Consumer Loans ACL. For those loans that do not share similar risk characteristics, the Company estimates the ACL on an individual (or loan by loan) basis. This population of individually evaluated loans (or loan relationships with the same primary source of repayment) is determined on a quarterly basis and consists of: loans with a risk rating of substandard or worse and a balance exceeding $ 500,000 , or loan terms differing significantly from other pooled loans. 11 Table of Contents In accordance with the Company’s policy, non-accrual residential real estate loans that are below $ 500,000 and well secured (loan-to-value < 60 %) are excluded from individually evaluated loans. Measurement of credit loss is based on the expected future cash flows of an individually evaluated loan, discounted at the loan’s effective interest rate or measured on an observable market value, if one exists, or the estimated market value of the collateral underlying the loan, discounted to consider estimated costs to sell the collateral for collateral-dependent loans. If the net value is less than the loan’s amortized cost, a specific reserve in the ACL is recorded, which is charged-off in the period when management believes the loan balance is no longer collectible. In the ordinary course of business, the Company enters into commitments to extend credit. Such financial instruments are recorded in the consolidated financial statements when they are funded. The credit risk associated with these commitments is evaluated in a manner similar to the ACL on loans. The reserve for unfunded commitments is included in other liabilities on the consolidated balance sheets.

These loans are starting to show signs of potential weakness and are being closely monitored by management. ​ Loans rated 7: Loans in this category are considered “substandard”. Generally, a loan is considered substandard if it is inadequately protected by the current net worth and paying capacity of the obligors and/or the collateral pledged. There is a distinct possibility that the Company will sustain some loss if the weakness is not corrected. ​ Loans rated 8: Loans in this category are considered “doubtful”. Loans classified as doubtful have all the weaknesses inherent in those classified as substandard with the added characteristic that the weaknesses make collection or liquidation in full, on the basis of currently existing facts, highly questionable and improbable. ​ 14 Table of Contents Loans rated 9: Loans in this category are considered uncollectible (“loss”) and of such little value that their continuance as loans is not warranted. ​ On an annual basis, or more often if needed, the Company reviews the accuracy of risk ratings for commercial real estate, construction and land development loans, and commercial and industrial loans based on various ongoing performance characteristics and supporting information that is provided from time to time by commercial borrowers. Annually, the Company engages an independent third-party to review a significant portion of loans within these segments. Management uses the results of these reviews as part of its annual review process. ​ The following table presents the amortized cost of loans receivable by internal risk grade by year of origination as of September 30, 2025.

The Company has an employee tax deferred incentive plan (the “401(k) plan”) under which the Company makes voluntary contributions within certain limitations. All employees who meet specified age and length of service requirements are el igible to participate in the 401(k) plan. ​ The amount contributed by the Company to the 401(k) Plan is included in salaries and employee benefits in the consolidated statements of income . The amounts contributed to the 401(k) plan for the three months ended September 30, 2025 and 2024 were $ 735,000 and $ 626,000 , respectively, and $ 2.2 million and $ 2.0 million for the nine months ended September 30, 2025 and 2024, re spectively. ​ Employee Pension Plan – The Company provided pension benefits through a defined benefit plan maintained with the Co-operative Banks Employees Retirement Association (“CBERA”) (the “Plan”). The Plan was a multi-employer plan whereby the contributions by each bank are not restricted to provide benefits to the employees of the contributing bank; therefore, the Company is not required to recognize the funded status of the plan on its consolidated balance sheet and need only accrue for any quarterly contributions due and payable on demand, or any withdrawal liabilities assessed by CBERA if the Company intended to withdraw from the Plan. ​ The Company froze its benefit accruals from the CBERA Plan as of December 31, 2023. The Company withdrew from the Plan in the second quarter of 2024. ​ During the three and nine months ended September 30, 2025, as part of the final liquidation of the employee pension plan, the Company received $ 739,000 as a result of an overfunding and contributed $ 480,000 , respectively. During the three and nine months ended September 30, 2024, an expense of $ 390,000 was recorded to reflect the estimated final withdrawal liability from the Plan. The expense was primarily driven by final computations for estimated payouts to participants . ​ 19 Table of Contents Officers’ Deferred Compensation Plans – During 2014, the Company put into place an unfunded, defined contribution, Non-qualified Deferred Compensation Pl an (“Deferred Comp Plan”) for select employees of the Company. The Officers’ Deferred Comp Plan was provided to key management of the Company and results in 5 % - 20 % of the employee’s then current base salary being credited to the participant’s account annually, subject to increases in annual base compensation and the possibility of additional discretionary contributions. The employees vest at varying dates in accordance with each individual’s deferred compensation participation agreement; however, all key officers will be fully vested upon the attainment of age 65. The obligations under these plans are included in accrued retirement liabilities on the Company’s consolidated balance sheets and approximated $ 2.3 million and $ 2.6 million as of September 30, 2025 and December 31, 2024, respectively. The expense under this plan (recorded in salaries and employee benefits in the consolidated statements of income) approximated $ 89,000 and $ 100,000 for the three months ended September 30, 2025 and 2024, respectively, and $ 266,000 and $ 299,000 for the nine months ended September 30, 2025 and 2024, r espectively. ​ Deferred Compensation Plans – In January 2022, the Company put into place an unfunded Non-qualified Deferred Compensation Plan (“Deferred Comp Plan”) for select employees of the Company. The Deferred Comp Plan was provided to key management of the Company and allows for the employees to defer amounts from their salary, bonus, or Long-Term Incentive Plan (“LTIP”) into the Deferred Comp Plan to be paid out at a future date. Amounts deferred under the Deferred Comp Plan increase in value based upon the growth of the Bank’s tangible capital, with the Compensation Committee holding discretionary authority. The obligations under the Deferred Comp Plan are included in accrued retirement liabilities on the Company’s consolidated balance sheets and approximated $ 4.9 million and $ 878,000 at September 30, 2025 and December 31, 2024, respectively. The expense under this plan (recorded in salaries and employee benefits in the consolidated statements of income) approximated $ 86,000 and $ 8,000 for the three months ended September 30, 2025 and 2024, respectively, and $ 258,000 and $ 24,000 for the nine months ended September 30, 2025 and 2024, respectively. ​ LTIP – In January 2020, the Company put into place a long-term incentive plan for certain members of its management team where benefits are awarded annually on a discretionary basis and cliff vest after three years . Under this plan, individuals are granted “phantom shares” and benefits are accrued based upon the projected growth of the Bank’s capital. The obligations under this plan are included in accrued retirement liabilities on the Company’s consolidated balance sheets and approximated $ 7.2 million and $ 14.6 million as of September 30, 2025 and December 31, 2024, respectively. The expense under this plan (recorded in salaries and employee benefits in the consolidated statements of income) approximated $ 946,000 and $ 1.8 million for the three months ended September 30, 2025 and 2024, respectively, and $ 2.6 million and $ 5.0 million for the nine months ended September 30, 2025 and 2024, respectively. ​ Director Pension Plan – The Company has a director defined benefit pension plan (“Director Pension Plan”), c overing directors who were in service prior to 2023 and have met the plan’s vesting requirements . The Company’s liabilities for the Director Pension Plan are calculated by an independent actuary who uses the “projected unit credit” actuarial method to determine the normal cost and actuarial liability. The liability for the Director Pension Plan amounted to $ 6.2 million and $ 5.7 million as of September 30, 2025 and December 31, 2024, respectively, and is recorded on the consolidated balance sheets. The expense under this plan (recorded in salaries and employee benefits in the consolidated statements of income) approximated $ 162,000 and $ 181,000 for the three months ended September 30, 2025 and 2024, respectively, and $ 486,000 and $ 542,000 for the nine months ended September 30, 2025 and 2024, respectively. ​ The Company records an estimate of net periodic pension cost for the director pension plan to accrued retirement liabilities on the consolidated balance sheet on a quarterly basis. Equity adjustments, to accumulated other comprehensive loss, in conjunction with the pension plan are recorded by the Company annually upon receipt of the independent actuarial report. ​ ​ ​ ​ 20 Table of Contents Employment and Change in Control Agreements – The Company has entered into an employment agreement with the Chief Executive Officer and has entered into Change in Control Agreements with its Chief Financial Officer and its Chief Operating Officer that renew for one additional year each June 5th, which provide severance payments in the event of the executive’s involuntary or constructive termination of employment, including upon a termination following a change in control as defined in the agreements. ​ Employee Stock Ownership Plan – As part of the Initial Public Offering ("IPO") completed on December 27, 2023, the Bank established a tax-qualified Employee Stock Ownership Plan ("ESOP") to provide eligible employees the opportunity to own Company shares. The ESOP borrowed $ 47.2 million from the Company to purchase 3,416,458 common shares on the open market. The loan is payable in annual installments over 20 years at an interest rate of 8.50 %, which was refinanced to 7.50 % during the nine months ended September 30, 2025. As the loan is repaid to the Company, shares are released and allocated proportionally to eligible participants on the basis of each participant’s proportional share of compensation relative to the compensation of all participants. The unallocated ESOP shares are pledged as collateral on the loan. ​ The Company accounts for its ESOP in accordance with FASB ASC 718-40, Compensation – Stock Compensation . Under this guidance, unreleased shares are deducted from shareholders’ equity as unearned ESOP shares on the accompanying consolidated balance sheets. ​ The Company recognizes compensation expense equal to the fair value of the ESOP shares during the periods in which they are committed to be released. To the extent that the fair value of the Company’s ESOP shares differs from the cost of such shares, the difference will be credited or debited to shareholders' equity. ​ As the loan is internally leveraged, the loan receivable from the ESOP to the Company is not reported as an asset nor is the debt of the ESOP shown as a liability on the Company’s consolidated balance sheets. Total compensation expense recognized in connection with the ESOP was $ 790,000 and $ 762,000 for the three months ended September 30, 2025 and 2024, respectively. Total compensation expense recognized in connection with the ESOP was $ 2.4 million and $ 2.0 million for the nine months ended September 30, 2025 and 2024, respectively. The following table presents share information held by the ESOP: ​ ​ ​ ​ ​ ​ ​ ​ ​ As of ​ ​ September 30, 2025 ​ December 31, 2024 ​ ​ (Dollars in thousands) Allocated shares ​ ​ 170,823 ​ ​ — Shares committed to be released ​ ​ 127,766 ​ ​ 170,823 Unallocated shares ​ ​ 3,117,869 ​ ​ 3,245,635 Total shares ​ ​ 3,416,458 ​ ​ 3,416,458 Fair value of unallocated shares ​ $ 55,030 ​ $ 58,616 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Stock-Based Compensation – On April 23, 2025, the shareholders of the Company approved the NB Bancorp, Inc. 2025 Equity Incentive Plan (“2025 Plan”). The 2025 Plan provides for the issuance of up to 5,987,802 shares of common stock pursuant to grants of restricted stock awards (“RSAs”), restricted stock units (“RSUs”), non-qualified stock options and incentive stock options, any or all of which can be granted with performance-based vesting conditions. Under the 2025 Plan, 1,708,229 shares may be issued as RSAs or RSUs, including those issued as performance shares and PSUs, and 4,270,573 shares may be issued upon the exercise of stock options. These shares may be awarded from the Company’s authorized but unissued shares. However, the 2025 Plan permits the grant of additional RSAs or RSUs above the aforementioned limit, provided that, for each additional share of RSA or RSU awarded in excess of such limit, the pool of shares available to be issued upon the exercise of stock options will be reduced by three shares. ​ The restricted stock awards are measured based on grant-date fair value, which reflects the 10-day volume-weighted average price of our stock, on the date of the grant. All of the restricted stock awards which have been granted to date vest over five years in equal portions beginning on the first anniversary date of the restricted stock award. During the three months ended September 30, 2025, the Company did no t have any restricted stock activity. 21 Table of Contents During the nine months ended September 30, 2025, the Company granted 1,284,525 shares of restricted stock with a weighted-average grant date fair value per share of $ 16.41 . During the three and nine months ended September 30, 2025, the Company recognized $ 1.1 million and $ 1.8 million of stock compensation expense, respectively. The Company did no t have any restricted stock activity or recognize any stock compensation expense during the three and nine months ended September 30, 2024. ​ ​ ​ Note 6 – Fair Value Measurements ASC 820-10, Fair Value Measurement – Overall (“ASC 820-10”) , provides a framework for measuring fair value under U.S. GAAP. This guidance also allows the Company the irrevocable option to elect fair value for the initial and subsequent measurement for certain financial assets and liabilities on a contract-by-contract basis. In accordance with ASC 820-10 , the Company groups its financial assets and financial liabilities measured at fair value in three levels, based on the markets in which the assets and liabilities are traded and the reliability of the assumptions used to determine fair value. Level 1 – Valuations for assets and liabilities traded in active exchange markets, such as the New York Stock Exchange. Valuations are obtained from readily available pricing sources for market transactions involving identical assets or liabilities. Level 2 – Valuations for assets and liabilities traded in less active dealer or broker markets. Valuations are obtained from third party pricing services for identical or comparable assets or liabilities. Level 3 – Valuations for assets and liabilities that are derived from other methodologies, including option pricing models, discounted cash flow models and similar techniques, and are not based on market exchange, dealer, or broker traded transactions. Level 3 valuations incorporate certain assumptions and projections in determining the fair value assigned to such assets and liabilities. 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. A description of the valuation methodologies used for instruments measured at fair value, as well as the general classification of such instruments pursuant to the valuation hierarchy, is set forth below. These valuation methodologies were applied to all of the Company’s financial assets and financial liabilities carried at fair value for September 30, 2025 and December 31, 2024. ​ Available-for-sale securities – Where quoted prices are available in an active market, securities are classified within Level 1 of the valuation hierarchy. Level 1 securities would include highly liquid government bonds (such as U.S. Treasuries), mortgage products and exchange traded equities. If quoted market prices are not available, then fair values are estimated by using pricing models, quoted prices of securities with similar characteristics, or discounted cash flows. Level 2 securities would include U.S. agency securities, mortgage-backed agency securities, obligations of states and political subdivisions, and certain corporate, asset-backed and other securities. In certain cases where there is limited activity or less transparency around inputs to the valuation, securities are classified within Level 3 of the valuation hierarchy. ​ Derivative arrangements – The fair values of derivative arrangements are estimated by the Company using a third-party derivative valuation expert who relies on Level 2 inputs, namely discounted cash flow models to determine a fair value by calculating a settlement termination value with the counterparty. 22 Table of Contents Assets measured and reported at estimated fair value on a recurring basis are summarized below: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ September 30, 2025 ​ Level 1 ​ Level 2 ​ Level 3 ​ Fair Value Assets: ​ (in thousands) Available-for-sale debt securities: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ U.S. Treasury securities ​ $ 69,023 ​ $ — ​ $ — ​ $ 69,023 U.S. Government agencies ​ ​ — ​ ​ 11,200 ​ ​ — ​ ​ 11,200 Agency mortgage-backed securities ​ ​ — ​ ​ 43,847 ​ ​ — ​ ​ 43,847 Agency collateralized mortgage obligations ​ ​ — ​ ​ 10,950 ​ ​ — ​ ​ 10,950 Corporate bonds ​ ​ — ​ ​ 73,329 ​ ​ 9,315 ​ ​ 82,644 Municipal obligations ​ ​ — ​ ​ 6,488 ​ ​ — ​ ​ 6,488 SBA securities ​ ​ — ​ ​ 6,871 ​ ​ — ​ ​ 6,871 Total available-for-sale debt securities ​ $ 69,023 ​ $ 152,685 ​ $ 9,315 ​ $ 231,023 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Derivative assets ​ $ — ​ $ 24,425 ​ $ — ​ $ 24,425 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Liabilities: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Derivative liabilities ​ $ — ​ $ 22,773 ​ $ — ​ $ 22,773 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ December 31, 2024 ​ Level 1 ​ Level 2 ​ Level 3 ​ Fair Value Assets: ​ (in thousands) Available-for-sale debt securities: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ U.S. Treasury securities ​ $ 69,084 ​ $ — ​ $ — ​ $ 69,084 U.S. Government agencies ​ ​ — ​ ​ 9,007 ​ ​ — ​ ​ 9,007 Agency mortgage-backed securities ​ ​ — ​ ​ 39,184 ​ ​ — ​ ​ 39,184 Agency collateralized mortgage obligations ​ ​ — ​ ​ 10,833 ​ ​ — ​ ​ 10,833 Corporate bonds ​ ​ — ​ ​ 75,147 ​ ​ 8,898 ​ ​ 84,045 Municipal obligations ​ ​ — ​ ​ 9,806 ​ ​ — ​ ​ 9,806 SBA securities ​ ​ — ​ ​ 6,246 ​ ​ — ​ ​ 6,246 Total available-for-sale debt securities ​ $ 69,084 ​ $ 150,223 ​ $ 8,898 ​ $ 228,205 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Derivative assets ​ $ — ​ $ 27,174 ​ $ — ​ $ 27,174 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Liabilities: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Derivative liabilities ​ $ — ​ $ 27,177 ​ $ — ​ $ 27,177 ​ The Company had no purchases, sales or transfers of level 3 assets during the three and nine months ended September 30, 2025 and 2024. The change in the value of Level 3 assets during the three and nine months ended September 30, 2025 was a direct result of the change in market value of the underlying securities. The Company may also be required from time to time to measure certain other assets at fair value on a non-recurring basis in accordance with U.S. GAAP. Any adjustments to fair value usually result in write-downs of individual assets. Collateral-Dependent Loans – Collateral-dependent loans with specific reserves are carried at fair value, which equals the estimated market value of the collateral less estimated costs to sell. Collateral may be in the form of real estate or business assets including equipment, inventory, and accounts receivable. A loan may have multiple types of collateral; however, the majority of the Company’s loan collateral is real estate. The value of real estate collateral is generally determined utilizing a market valuation approach based on an appraisal conducted by an independent, licensed appraiser outside of the Company using observable market data (Level 2). However, if the collateral value is significantly adjusted due to differences in the comparable properties or is discounted by the Company because of lack of marketability, then the fair value is considered Level 3. The value of business equipment is based upon an outside appraisal if deemed significant or the net book value on the applicable borrower’s financial statements if not considered significant. 23 Table of Contents Likewise, values for inventory and accounts receivables collateral are based on financial statement balances or aging reports (Level 3). In limited circumstances, the collateral value for a collateral-dependent loan may be based on the enterprise value of a company. The enterprise value method involves assessing the borrower’s ability to repay the loan by estimating the total value of its business, including both debt and equity. This approach is typically used where the recoverable value is based on the fair value of the company as a going concern, adjusted for the priority of the Company’s claim. Fair value adjustments are recorded in the period incurred as provision for credit losses in the consolidated statements of income. The Company had no liabilities measured at fair value on a non-recurring basis. The following table summarizes assets measured at fair value on a non-recurring basis: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ September 30, 2025 ​ Level 1 Level 2 Level 3 Fair Value ​ ​ (in thousands) Collateral-dependent loans, net of reserve ​ $ — ​ $ — ​ $ 8,669 ​ $ 8,669 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ December 31, 2024 ​ Level 1 Level 2 Level 3 Fair Value ​ ​ (in thousands) Collateral-dependent loans, net of reserve ​ $ — ​ $ — ​ $ 10,951 ​ $ 10,951 ​ For Level 3 assets and liabilities measured at fair value on a nonrecurring basis as of September 30, 2025 and December 31, 2024, the significant unobservable inputs used in the fair value measurements were as follows: ​ ​ ​ ​ ​ ​ ​ ​ ​ Significant Significant ​ ​ Valuation ​ Observable ​ Unobservable ​ ​ Technique ​ Inputs ​ Inputs Collateral-dependent loans Appraisal Value / Comparison Sales / Enterprise Value Appraisals and/or sales of comparable properties or financial statements of the business Appraisals discounted 5 to 20 % for sales commission and other holding costs; Enterprise value discounts of assets, liabilities and equity ​ ASC Topic 825, Financial Instruments (ASC 825) , requires disclosure of the fair value of financial assets and financial liabilities, including those financial assets and financial liabilities that are not measured and reported at fair value on a recurring or non-recurring basis. The methodologies for estimating the fair value of financial assets and financial liabilities that are measured at fair value on a recurring or non-recurring basis are discussed above. ​ ASC 825 requires public business entities to use the exit price notion when measuring the fair value of financial instruments for disclosure purposes. The exit price notion is a market-based measurement of fair value that is represented by the price to sell an asset or transfer a liability in the principal market (or most advantageous market in the absence of a principal market) on the measurement date. As of September 30, 2025 and December 31, 2024, fair values of loans are estimated on an exit price basis incorporating discounts for credit, liquidity and marketability factors. ​ 24 Table of Contents The following tables present the estimated fair values, related carrying amounts, and valuation level of the financial instruments as of the dates stated: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ September 30, 2025 ​ ​ Carrying ​ Fair ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Amount ​ Value ​ Level 1 ​ Level 2 ​ Level 3 ​ ​ (In thousands) Financial Assets: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Cash and cash equivalents ​ $ 295,377 ​ $ 295,377 ​ $ 295,377 ​ $ — ​ $ — Loans receivable, net ​ ​ 4,673,077 ​ ​ 4,613,357 ​ ​ — ​ ​ — ​ ​ 4,613,357 Accrued interest receivable ​ ​ 21,074 ​ ​ 21,074 ​ ​ 21,074 ​ ​ — ​ ​ — FHLB stock ​ ​ 11,541 ​ ​ 11,541 ​ ​ — ​ ​ 11,541 ​ ​ — FRB stock ​ ​ 12,831 ​ ​ 12,831 ​ ​ — ​ ​ 12,831 ​ ​ — Non-public investments ​ ​ 20,159 ​ ​ 20,159 ​ ​ — ​ ​ — ​ ​ 20,159 BOLI ​ ​ 56,342 ​ ​ 56,342 ​ ​ — ​ ​ 56,342 ​ ​ — ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Financial Liabilities: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Deposits, other than time deposits ​ $ 2,418,955 ​ $ 2,418,955 ​ $ 2,418,955 ​ $ — ​ $ — Time deposits ​ ​ 2,146,709 ​ ​ 2,147,754 ​ ​ — ​ ​ 2,147,754 ​ ​ — FHLB borrowings ​ ​ 41,453 ​ ​ 41,337 ​ ​ — ​ ​ 41,337 ​ ​ — ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ December 31, 2024 ​ ​ Carrying ​ Fair ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Amount ​ Value ​ Level 1 ​ Level 2 ​ Level 3 ​ ​ (In thousands) Financial Assets: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Cash and cash equivalents ​ $ 363,855 ​ $ 363,855 ​ $ 363,855 ​ $ — ​ $ — Loans receivable, net ​ ​ 4,294,408 ​ ​ 4,196,079 ​ ​ — ​ ​ — ​ ​ 4,196,079 Accrued interest receivable ​ ​ 19,685 ​ ​ 19,685 ​ ​ 19,685 ​ ​ — ​ ​ — FHLB stock ​ ​ 6,728 ​ ​ 6,728 ​ ​ — ​ ​ 6,728 ​ ​ — FRB stock ​ ​ 12,142 ​ ​ 12,142 ​ ​ — ​ ​ 12,142 ​ ​ — Non-public investments ​ ​ 5,494 ​ ​ 5,494 ​ ​ — ​ ​ — ​ ​ 5,494 BOLI ​ ​ 102,785 ​ ​ 102,785 ​ ​ — ​ ​ 102,785 ​ ​ — ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Financial Liabilities: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Deposits, other than time deposits ​ $ 2,214,372 ​ $ 2,214,372 ​ $ 2,214,372 ​ $ — ​ $ — Time deposits ​ ​ 1,963,280 ​ ​ 1,964,801 ​ ​ — ​ ​ 1,964,801 ​ ​ — FHLB borrowings ​ ​ 120,835 ​ ​ 120,778 ​ ​ — ​ ​ 120,778 ​ ​ — ​ ​ Note 7 – Commitments and Contingencies 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 financial instruments include commitments to originate loans, to disburse funds to borrowers on unused construction and land development loans, and to disburse funds on committed but unused lines of credit. These financial agreements involve, to varying degrees, elements of credit and interest rate risk in excess of the amount recognized in the consolidated balance sheets. The contract amounts of these instruments reflect the extent of involvement the Company has in particular classes of financial instruments. Commitments to originate loans and disburse additional funds to borrowers on lines of credit are agreements to lend to a customer provided there is no violation of any condition established in the contract. Commitments generally have fixed expiration dates or other termination clauses and may require payment of a fee. 25 Table of Contents The Company evaluates each customer’s creditworthiness on a case-by-case basis. The amount of collateral obtained, if deemed necessary by the Company upon extension of credit, is based on management’s credit evaluation of the borrower. The Company’s exposure to credit loss in the event of nonperformance by the other party to the financial instrument for loan commitments, 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. The commitments to originate loans and lines of credit may expire without being funded or drawn upon; therefore, the total commitment amounts do not necessarily represent future cash requirements. Standby letters of credit are conditional commitments issued by the Company to guarantee the performance by a customer to a third party. The credit risk involved in issuing letters of credit is essentially the same as that involved in extending loan facilities to customers. As of September 30, 2025 and December 31, 2024, the maximum potential amount of the Company’s obligation was $ 5.6 million and $ 6.0 million, respectively, for standby letters of credit. The Company’s outstanding letters of credit generally have a term of less than one year. If a letter of credit is drawn upon, the Company may seek recourse through the customer’s underlying line of credit. If the customer’s line of credit is also in default, the Company may take possession of the collateral, if any, securing the line of credit. ​ Financial instruments whose contract amounts represent off-balance sheet credit risk and are not reflected on the Company’s consolidated balance sheets consist of the following at the dates stated: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ As of ​ ​ September 30, 2025 ​ December 31, 2024 ​ ​ (In thousands) ​ ​ ​ ​ ​ ​ ​ Commitments to originate loans ​ $ 22,141 ​ $ 34,050 Unadvanced funds on lines of credit ​ ​ 636,648 ​ ​ 495,796 Unadvanced funds on construction loans ​ ​ 425,944 ​ ​ 416,450 Letters of credit ​ ​ 5,608 ​ ​ 6,043 ​ ​ $ 1,090,341 ​ $ 952,339 ​ The Bank accrues for credit losses related to off-balance sheet financial instruments. Potential losses on off-balance sheet loan commitments are estimated using the same risk factors used to determine the ACL on loans, adjusted for the likelihood that funding will occur. The allowance for off-balance sheet commitments is recorded within other liabilities on the consolidated balance sheets and amounted to $ 2.7 million and $ 3.2 million as of September 30, 2025 and December 31, 2024, respectively. For the three months ended September 30, 2025 the Company recorded a provision for credit losses in the allowance for unfunded commitments of $ 355,000 , compared to a release of the allowance for unfunded commitments of $ 2.4 million for the three months ended September 30, 2024. For the nine months ended September 30, 2025 and 2024, the Company recorded a release of the allowance for unfunded commitments of $ 517,000 and $ 2.6 million, respectively. ​ ​ Note 8 – Derivatives and Hedging Activities Risk Management Objective of Using Derivatives – 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, liquidity, and credit risk primarily by managing the amount, sources, and duration of its assets and liabilities and the use of derivative financial instruments. Specifically, the Company enters into derivative financial instruments to manage exposures that arise from business activities that result in the receipt or payment of future known and uncertain cash amounts, the value of which are determined by interest rates. 26 Table of Contents The Company’s derivative financial instruments are used to manage differences in the amount, timing, and duration of the Company’s known or expected cash receipts and its known or expected cash payments principally related to the Company’s assets and liabilities. Interest rate positions – The Company may utilize various interest rate derivatives as hedging instruments against interest rate risk associated with the Company’s borrowings and loan portfolios. An interest rate derivative is an agreement whereby one party agrees to pay a floating rate of interest on a notional principal amount in exchange for receiving a fixed rate of interest on the same notional amount, for a predetermined period of time, from a second party. The amounts relating to the notional principal amount are not actually exchanged. The following table reflects information about the Company’s derivative positions at the dates indicated below for interest rate swaps which qualify as cash flow hedges for accounting purposes: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ September 30, 2025 ​ ​ ​ ​ ​ ​ Weighted Average Rate ​ ​ ​ ​ ​ Notional ​ Weighted Average ​ Current Rate ​ Current Rate ​ ​ ​ ​ Amount ​ Maturity ​ Paid ​ Received ​ ​ Fair Value ​ (in thousands) ​ (in years) ​ ​ ​ ​ ​ ​ (in thousands) Interest rate swaps $ 300,000 ​ 3.5 ​ 4.31 % 3.44 % ​ $ 1,592 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Total $ 300,000 ​ ​ ​ ​ ​ ​ ​ ​ $ 1,592 ​ The maximum length of time over which the Company is currently hedging its exposure to the variability in future cash flows for forecasted transactions related to the payment of variable interest on existing financial instruments is 3 years . Included in the table above is a forward-starting interest rate swap with a notional amount of $ 150 million, which does not begin exchanging cash flows until Q3 2026 and carries a 3-year term during the swap period. For derivative instruments that are designated and qualify as cash flow hedging instruments, the effective portion of the gains or losses is reported as a component of other comprehensive income and is subsequently reclassified into earnings in the period that the hedged forecasted transaction affects earnings. The Company expects approximately $ 54,000 (pre-tax) to be reclassified as an increase to net interest income from other comprehensive income related to the Company’s cash flow hedges in the twelve months following September 30, 2025. This reclassification is due to anticipated payments that will be made and/or received on the swaps based upon the forward curve at September 30, 2025. The Company had no hedges in place for the three and nine months ended September 30, 2024. Non-designated Hedges – Derivatives not designated as hedges are not speculative and are used to manage the Company’s exposure to interest rate movements and other identified risks but do not meet the strict hedge accounting requirements and/or the Company has not elected to apply hedge accounting. Changes in the fair value of derivatives not designated in hedging relationships, exclusive of credit valuation adjustments, are recorded directly in earnings. The Company executes interest rate swaps and cap agreements with commercial banking customers to facilitate its respective risk management strategies. Those interest rate swap and cap agreements are simultaneously hedged by offsetting interest rate swaps and caps that are executed with a third party, such that the Company minimizes its net risk exposure resulting from such transactions. As of September 30, 2025, the Company had 71 interest rate swap agreements with an aggregate notional amount of $ 458.7 million compared to 67 interest rate swap agreements with an aggregate notional amount of $ 429.9 million related to this program as of December 31, 2024. Risk Participation Agreements – Risk Participation Agreements (“RPAs”) are guarantees issued by the Company to other parties for a fee, whereby the Company agrees to participate in the credit risk of a derivative customer of the other party. Under the terms of these agreements, the “participating bank” receives a fee from the “lead bank” in exchange for the guarantee of reimbursement if the customer defaults on an interest rate swap. 27 Table of Contents The interest rate swap is transacted such that any and all exchanges of interest payments (favorable and unfavorable) are made between the lead bank and the customer. In the event that an early termination of the swap occurs, and the customer is unable to make a required close out payment, the participating bank assumes that obligation and is required to make this payment. RPAs where the Company acts as the lead bank are referred to as “participations out,” in reference to the credit risk associated with the customer derivatives being transferred out of the Company. Participations out generally occur concurrently with the sale of new customer derivatives. RPAs where the Company acts as the participating bank are referred to as “participations-in,” in reference to the credit risk associated with the counterparty’s derivatives being assumed by the Company. The Company’s maximum credit exposure is based on its proportionate share of the settlement amount of the referenced interest rate swap. Settlement amounts are generally calculated based on the fair value of the swap plus outstanding accrued interest receivable from the customer. As of September 30, 2025, the Company had 17 RPAs with an aggregate notional amount of $ 44.7 million related to this program compared to 17 RPAs with an aggregate notional amount of $ 44.9 million as of December 31, 2024. These RPAs all represent “participations-in” and generally have terms ranging from five to ten years . ​ The table below presents the fair value of the Company’s derivative financial instruments not designated as hedging instruments, as well as their classification on the consolidated balance sheets as of the dates stated: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Derivative ​ Derivative ​ ​ Assets (1) ​ Liabilities (2) September 30, 2025 ​ (in thousands) Derivatives not designated as hedging instruments: ​ ​ ​ ​ ​ ​ Interest rate products ​ $ 22,772 ​ $ 22,771 RPA credit contracts ​ ​ — ​ ​ 2 Total derivatives not designated as hedging instruments ​ $ 22,772 ​ $ 22,773 ​ ​ ​ ​ ​ ​ ​ December 31, 2024 ​ ​ ​ ​ ​ ​ Derivatives not designated as hedging instruments: ​ ​ ​ ​ ​ ​ Interest rate products ​ $ 27,174 ​ $ 27,174 RPA credit contracts ​ ​ — ​ ​ 3 Total derivatives not designated as hedging instruments ​ $ 27,174 ​ $ 27,177 (1) Recorded in prepaid expenses and other assets on the consolidated balance sheets. (2) Recorded in accrued expenses and other liabilities on the consolidated balance sheets. ​ Swap contract fees, net of brokerage costs, recognized in earnings on the above noted interest rate products and RPA contracts approximated $ 208,000 and $ 375,000 for the three months ended September 30, 2025 and 2024, respectively, and $ 820,000 and $ 1.1 million for the nine months ended September 30, 2025 and 2024, respectively. The Company has agreements with each of its derivative counterparties that contain a provision where if the Company defaults (or is capable of being declared in default) on any of its indebtedness, then the Company could also be declared in default on its derivative obligations, and it could be required to terminate its derivative positions with the counterparty. The Company also has agreements with certain of its derivative counterparties that contain a provision whereby if the counterparty fails to maintain its status as a well-capitalized institution, then the Company could be required to terminate its derivative positions with the counterparty. In order to mitigate counterparty default risk in conjunction with these interest rate products and RPA credit contracts, the Company was required to maintain $ 9.1 million of collateral deposit accounts with the counterparties to these agreements as of September 30, 2025 and December 31, 2024. ​ Note 9 – Other Comprehensive Income (Loss) U.S. GAAP generally requires that recognized revenue, expenses, gains and losses be included in net income. Although certain changes in assets and liabilities are reported as a separate component of the shareholders' equity section of the consolidated balance sheets, such items, along with net income, are components of comprehensive income (loss). 28 Table of Contents The components of other comprehensive income (loss) and related tax effects are as follows for the periods indicated: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ For the Three Months Ended ​ September 30, 2025 September 30, 2024 ​ ​ (In thousands) ​ ​ Pre-Tax ​ Tax ​ After-Tax ​ Pre-Tax ​ Tax ​ After-Tax ​ ​ Amount ​ Expense ​ Amount ​ Amount ​ (Expense) Benefit ​ Amount ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Change in fair value of available-for-sale securities ​ $ 2,379 ​ $ ( 599 ) ​ $ 1,780 ​ $ 7,274 ​ $ ( 1,957 ) ​ $ 5,317 Less: Reclassification adjustment for net realized (losses) gains in net income ​ ​ — ​ ​ — ​ ​ — ​ ​ ( 1,868 ) ​ ​ 542 ​ ​ ( 1,326 ) Net change in fair value of available-for-sale securities ​ ​ 2,379 ​ ​ ( 599 ) ​ ​ 1,780 ​ ​ 5,406 ​ ​ ( 1,415 ) ​ ​ 3,991 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Change in fair value of cash flow hedges ​ ​ 1,653 ​ ​ ( 413 ) ​ ​ 1,240 ​ ​ — ​ ​ — ​ ​ — ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Total other comprehensive income (loss) ​ $ 4,032 ​ $ ( 1,012 ) ​ $ 3,020 ​ $ 5,406 ​ $ ( 1,415 ) ​ $ 3,991 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ For the Nine Months Ended ​ September 30, 2025 September 30, 2024 ​ ​ (In thousands) ​ ​ Pre-Tax ​ Tax ​ After-Tax ​ Pre-Tax ​ Tax ​ After-Tax ​ ​ Amount ​ Expense ​ Amount ​ Amount ​ (Expense) Benefit ​ Amount ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Change in fair value of available-for-sale securities ​ $ 5,077 ​ $ ( 1,272 ) ​ $ 3,805 ​ $ 8,309 ​ $ ( 2,231 ) ​ $ 6,078 Less: Reclassification adjustment for net realized (losses) gains in net income ​ ​ — ​ ​ — ​ ​ — ​ ​ ( 1,868 ) ​ ​ 543 ​ ​ ( 1,325 ) Net change in fair value of available-for-sale securities ​ ​ 5,077 ​ ​ ( 1,272 ) ​ ​ 3,805 ​ ​ 6,441 ​ ​ ( 1,688 ) ​ ​ 4,753 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Change in fair value of cash flow hedge ​ ​ 1,653 ​ ​ ( 413 ) ​ ​ 1,240 ​ ​ — ​ ​ — ​ ​ — ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Total other comprehensive income (loss) ​ $ 6,730 ​ $ ( 1,685 ) ​ $ 5,045 ​ $ 6,441 ​ $ ( 1,688 ) ​ $ 4,753 ​ The following table presents the components of accumulated other comprehensive loss as of September 30, 2025 and December 31, 2024: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ As of ​ ​ September 30, 2025 ​ December 31, 2024 ​ ​ (In thousands) ​ ​ ​ ​ ​ ​ ​ Net unrealized holding losses on available-for-sale securities, net of tax ​ $ ( 3,582 ) ​ $ ( 7,387 ) Net change in fair value of cash flow hedge, net of tax ​ ​ 1,240 ​ ​ — Unrecognized director pension plan benefits, net of tax ​ ​ ( 780 ) ​ ​ ( 780 ) Total accumulated other comprehensive loss ​ $ ( 3,122 ) ​ $ ( 8,167 ) ​ ​ ​ Note 10 – Regulatory Capital Requirements ​ The Company and the Bank are subject to various regulatory capital requirements administered by the federal banking agencies. Failure to meet minimum capital requirements can initiate certain mandatory and possibly additional discretionary actions by regulators that, if undertaken, could have a direct material effect on the Company’s consolidated financial statements. Under regulatory capital adequacy guidelines and the regulatory framework for prompt corrective action, the Company must meet specific capital guidelines that involve quantitative measures of the Company’s assets, liabilities, and certain off-balance-sheet items as calculated under regulatory accounting practices. The Company’s capital amounts and classification are also subject to qualitative judgments by the regulators about components, risk weightings, and other factors. ​ ​ 29 Table of Contents The Company operated under the risk-based framework as of September 30, 2025 and December 31, 2024. Under this framework, quantitative measures established by regulation to ensure capital adequacy require the Company to maintain minimum amounts and ratios of Total Capital, Tier 1 Capital and Common Equity Tier 1 Capital to Risk-Weighted Assets, and Tier 1 Capital to Total Average Assets (as defined in the regulations). ​ Management believes, as of September 30, 2025 and December 31, 2024, that the Company and the Bank meet all capital adequacy requirements to which each is subject. ​ As of September 30, 2025 and December 31, 2024, the Company and the Bank were categorized as well capitalized under the regulatory framework for prompt corrective action. To be categorized as well capitalized, the Bank must maintain minimum total risk-based, Tier 1 risk-based, Common Equity Tier 1 risk-based and Tier 1 leverage ratios as set forth in the table below. There are no conditions or events since that notification that management believes have changed the Bank’s or Company’s category. ​ The Bank’s actual capital amounts and ratios are presented in the table as of the date indicated: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ To be well capitalized ​ ​ ​ ​ ​ ​ ​ ​ For minimum capital ​ ​ under prompt corrective ​ ​ ​ Actual ​ ​ adequacy purposes ​ ​ action provisions ​ Amount Ratio Amount Ratio Amount Ratio September 30, 2025 ​ ​ (in thousands) ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Total Capital ​ $ 699,582 ​ 13.9 % ​ $ 401,533 ​ 8.0 % ​ $ 501,917 ​ 10.0 % (to Risk-Weighted Assets) ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Tier 1 Capital ​ ​ 653,844 ​ 13.0 % ​ ​ 301,150 ​ 6.0 % ​ ​ 401,533 ​ 8.0 % (to Risk-Weighted Assets) ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Common Equity Tier I Capital ​ ​ 653,844 ​ 13.0 % ​ ​ 225,862 ​ 4.5 % ​ ​ 326,246 ​ 6.5 % (to Risk-Weighted Assets) ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Tier 1 Capital ​ ​ 653,844 ​ 12.6 % ​ ​ 207,685 ​ 4.0 % ​ ​ 259,606 ​ 5.0 % (to Total Average Assets) ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ To be well capitalized ​ ​ ​ ​ ​ ​ ​ ​ For minimum capital ​ ​ under prompt corrective ​ ​ ​ Actual ​ ​ adequacy purposes ​ ​ action provisions ​ Amount Ratio Amount Ratio Amount Ratio December 31, 2024 ​ ​ (in thousands) ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Total Capital ​ $ 656,103 ​ 14.1 % ​ $ 372,083 ​ 8.0 % ​ $ 465,104 ​ 10.0 % (to Risk-Weighted Assets) ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Tier 1 Capital ​ ​ 614,156 ​ 13.2 % ​ ​ 279,063 ​ 6.0 % ​ ​ 372,083 ​ 8.0 % (to Risk-Weighted Assets) ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Common Equity Tier I Capital ​ ​ 614,156 ​ 13.2 % ​ ​ 209,297 ​ 4.5 % ​ ​ 302,318 ​ 6.5 % (to Risk-Weighted Assets) ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Tier 1 Capital ​ ​ 614,156 ​ 12.5 % ​ ​ 196,435 ​ 4.0 % ​ ​ 245,544 ​ 5.0 % (to Total Average Assets) ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ 30 Table of Contents The Company’s actual consolidated capital amounts and ratios are presented in the table as of the date indicated: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ To be well capitalized ​ ​ ​ ​ ​ ​ ​ ​ For minimum capital ​ ​ under prompt corrective ​ ​ ​ Actual ​ ​ adequacy purposes ​ ​ action provisions ​ Amount Ratio Amount Ratio Amount Ratio September 30, 2025 ​ ​ (in thousands) ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Total Capital ​ $ 785,198 ​ 15.6 % ​ $ 403,006 ​ 8.0 % ​ $ 503,757 ​ 10.0 % (to Risk-Weighted Assets) ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Tier 1 Capital ​ ​ 739,460 ​ 14.7 % ​ ​ 302,254 ​ 6.0 % ​ ​ 403,006 ​ 8.0 % (to Risk-Weighted Assets) ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Common Equity Tier I Capital ​ ​ 739,460 ​ 14.7 % ​ ​ 226,691 ​ 4.5 % ​ ​ 327,442 ​ 6.5 % (to Risk-Weighted Assets) ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Tier 1 Capital ​ ​ 739,460 ​ 14.0 % ​ ​ 211,148 ​ 4.0 % ​ ​ 263,935 ​ 5.0 % (to Total Average Assets) ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ To be well capitalized ​ ​ ​ ​ ​ ​ ​ ​ For minimum capital ​ ​ under prompt corrective ​ ​ ​ Actual ​ ​ adequacy purposes ​ ​ action provisions ​ Amount Ratio Amount Ratio Amount Ratio December 31, 2024 ​ ​ (in thousands) ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Total Capital ​ $ 814,505 ​ 17.4 % ​ $ 374,650 ​ 8.0 % ​ $ 468,313 ​ 10.0 % (to Risk-Weighted Assets) ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Tier 1 Capital ​ ​ 772,558 ​ 16.5 % ​ ​ 280,988 ​ 6.0 % ​ ​ 374,650 ​ 8.0 % (to Risk-Weighted Assets) ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Common Equity Tier I Capital ​ ​ 772,558 ​ 16.5 % ​ ​ 210,741 ​ 4.5 % ​ ​ 304,403 ​ 6.5 % (to Risk-Weighted Assets) ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Tier 1 Capital ​ ​ 772,558 ​ 15.3 % ​ ​ 202,436 ​ 4.0 % ​ ​ 253,045 ​ 5.0 % (to Total Average Assets) ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Note 11 – Earnings Per Share (“EPS”) ​ Basic EPS represents net income available to common shareholders divided by the weighted-average number of common shares outstanding during the period. Diluted EPS have been calculated in a manner similar to that of basic EPS except that the weighted-average number of common shares outstanding is increased to include the number of additional common shares that would have been outstanding if all potentially dilutive common shares (such as those resulting from the vesting of restricted stock awards) were issued during the period, computed using the treasury stock method.
