Notes to Unaudited Consolidated Financial Statements ​ Note 1 – Corporate Structure and Nature of Operations; Basis of Presentation ​ Corporate Structure and Nature of Operations ​ NB Bancorp, Inc., a Maryland corporation (the “Company”), 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 and southern New Hampshire. ​ The activities of the Company and the Bank are subject to the regulatory supervision of the Board of Governors of the Federal Reserve System and the Massachusetts Commissioner of Banks. The Company and the activities of the Bank and its subsidiaries are also subject to various Massachusetts business and banking regulations. ​ Conversion ​ Effective December 27, 2023, NB Financial, MHC (the “MHC”), the Bank’s former mutual holding company and the predecessor of the Company, converted from a mutual holding company into a publicly traded stock form of organization. In connection with the conversion, the Company sold 40,997,500 shares of common stock in a public offering at $ 10.00 per share for net offering proceeds of approximately $ 400.4 million. Additionally, the Company donated $ 2.0 million of cash and 1,708,229 shares of common stock to the Needham Bank Charitable Foundation (the “Foundation”). ​ In connection with the conversion, liquidation accounts are established by the Company and the Bank in an aggregate amount equal to (i) the MHC’s ownership interest in the shareholders’ equity of NB Financial, Inc. as of the date of the latest statement of financial condition included in the Company’s definitive prospectus dated October 12, 2023, plus (ii) the value of the net assets of the MHC as of the date of the MHC’s latest statement of financial condition before the consummation of the Conversion (excluding the MHC’s ownership interest in NB Financial, Inc.). Each eligible account holder and supplemental eligible account holder is entitled to a proportionate share of the liquidation accounts in the event of a liquidation of (i) the Company and the Bank or (ii) the Bank, and only in such events. This share will be reduced if the eligible account holder’s or supplemental account holder’s deposit balance falls below the amounts on the date of record and will cease to exist if the account is closed. The liquidation account will never be increased despite any increase after conversion in the related deposit balance. The Bank may not pay a dividend on its capital stock if the effect thereof would cause retained earnings to be reduced below the liquidation account amount or regulatory capital requirements. ​ 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. ​ 7 Table of Contents The accompanying Consolidated Balance Sheet as of March 31, 2026, the Consolidated Statements of Income, of Comprehensive Income, of Changes in Shareholders’ Equity and of Cash Flows for the three months ended March 31, 2026 and 2025 are unaudited. The Consolidated Balance Sheet as of December 31, 2025 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, 2025, 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 months ended March 31, 2026 are not necessarily indicative of results to be expected for the year ending December 31, 2026, any other interim period, or any future year or period. ​ The Company qualifies as an emerging growth company (“EGC”) under the Jumpstart Our Business Startups Act of 2012 and has the ability 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 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. ​ Provident Bancorp, Inc. and BankProv Acquisition ​ On November 15, 2025, the Company completed its acquisition of Provident Bancorp, Inc. and BankProv (“Provident”). The total consideration paid in the acquisition of Provident was $ 111.8 million in cash and the issuance of 5,943,682 shares of common stock valued at $ 114.7 million. The acquisition added $ 1.40 billion of total assets, $ 1.23 billion of total loans and $ 1.14 billion in total deposits, each at fair value, as of the date of closing. ​ The acquisition was accounted for under the acquisition method of accounting in accordance with ASC Topic 805, Business Combinations . Under this method of accounting, the respective assets acquired and liabilities assumed were recorded at their estimated fair values. The excess of consideration paid over the estimated fair value of the net assets acquired totaled $ 18.5 million and was recorded as goodwill. The results of Provident’s operations were included in the Company’s consolidated financial statements beginning on November 15, 2025. ​ The calculation of goodwill is subject to change for up to one year after the closing date of the transaction as additional information relative to closing date estimated and uncertainties becomes available. The Company made no adjustments to Goodwill during the three months ended March 31, 2026. ​ Operating Segments ​ Reportable segments are 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 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. ​ 8 Table of Contents Note 2 – Summary of Significant Accounting Policies ​ Use of Estimates ​ The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities, and the reported amounts of revenues and expenses. Actual results could differ from those estimates. ​ Material estimates that are particularly susceptible to significant change in the near term relate to the determination of the Allowance for Credit Losses (“ACL”) on loans, fair value determination of acquired assets and liabilities and resulting accretion and amortization of purchase accounting premiums/discounts, the valuation of real estate acquired in connection with foreclosures or in satisfaction of loans, the valuation of deferred tax assets, actuarial estimates related to the Company’s retirement programs, the valuation of financial instruments and impairment of goodwill and other intangibles. In connection with the determination of the ACL and foreclosed real estate, management obtains independent appraisals for significant properties. ​ A majority of the Company's loan portfolio consists of one-to-four-family residential, commercial real estate and construction and land development loans in the metro-west area of Boston and its surrounding communities. Accordingly, the ultimate collectability of a substantial portion of the Company's loan portfolio and the recovery of the carrying amount of foreclosed real estate are susceptible to changes in local market conditions. ​ While management uses currently available information to recognize losses on loans and foreclosed real estate, future additions to the ACL and valuation reserves on foreclosed real estate may be necessary based on changes in local economic conditions. In addition, regulatory agencies, as an integral part of their examination process, periodically review the Company’s ACL on loans and valuation reserves on foreclosed real estate. Such agencies may require the Company to recognize additions to the ACL on loans and valuation reserves on foreclosed real estate based on their judgments about information available to them at the time of their examination. Because of these factors, it is reasonably possible that the ACL on loans and valuation reserves on foreclosed real estate may change in the near future. ​ Business Combinations – Acquisitions of businesses are accounted for using the acquisition method of accounting. In accordance with applicable accounting guidance, we recognize assets acquired and liabilities assumed at their respective fair values as of the date of acquisition, with the related transaction costs expensed in the period incurred. We use third party valuation specialists to assist in the determination of fair value of certain assets and liabilities at the merger date, including loans and core deposit intangibles. While we use our best estimates and assumptions to accurately value assets acquired and liabilities assumed on the acquisition date, the estimates are inherently uncertain. ​ For further discussion of our methodology for estimating the fair value of acquired assets and assumed liabilities in connection with our Provident Acquisition, see Note 1 – Corporate Structure and Nature of Operations; Basis of Presentation – Provident Bancorp, Inc. and BankProv Acquisition . ​ Recent Accounting Pronouncements ​ Relevant standards that were recently issued but not yet adopted as of March 31, 2026: ​ 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. ​ 9 Table of Contents Other accounting standards that have been issued or proposed by the FASB or other standards-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 (“AFS”) securities are carried at fair value. For AFS 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 AFS 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. 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 March 31, 2026 ​ (in thousands) Available-for-Sale Debt Securities: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ U.S. Treasury securities ​ $ 96,467 ​ $ 132 ​ $ ( 278 ) ​ $ — ​ $ 96,321 U.S. Government agencies ​ ​ 4,670 ​ ​ 20 ​ ​ ( 4 ) ​ ​ — ​ ​ 4,686 Agency mortgage-backed securities ​ ​ 91,838 ​ ​ 100 ​ ​ ( 2,085 ) ​ ​ — ​ ​ 89,853 Agency collateralized mortgage obligations ​ ​ 11,321 ​ ​ 191 ​ ​ ( 125 ) ​ ​ — ​ ​ 11,387 Corporate bonds ​ ​ 64,702 ​ ​ 271 ​ ​ ( 2,976 ) ​ ​ — ​ ​ 61,997 Municipal obligations ​ ​ 6,599 ​ ​ — ​ ​ ( 59 ) ​ ​ — ​ ​ 6,540 SBA securities ​ ​ 6,574 ​ ​ — ​ ​ ( 117 ) ​ ​ — ​ ​ 6,457 Total ​ $ 282,171 ​ $ 714 ​ $ ( 5,644 ) ​ $ — ​ $ 277,241 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Amortized ​ Unrealized ​ Unrealized ​ Allowance for ​ ​ ​ ​ ​ ​ ​ Cost ​ ​ ​ Gain ​ ​ ​ Loss ​ Credit Losses ​ ​ ​ Fair Value December 31, 2025 ​ (in thousands) Available-for-Sale Debt Securities: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ U.S. Treasury securities ​ $ 95,479 ​ $ 407 ​ $ ( 103 ) ​ $ — ​ $ 95,783 U.S. Government agencies ​ ​ 9,159 ​ ​ 53 ​ ​ — ​ ​ — ​ ​ 9,212 Agency mortgage-backed securities ​ ​ 69,682 ​ ​ 162 ​ ​ ( 1,253 ) ​ ​ — ​ ​ 68,591 Agency collateralized mortgage obligations ​ ​ 12,109 ​ ​ 202 ​ ​ ( 74 ) ​ ​ — ​ ​ 12,237 Corporate bonds ​ ​ 72,703 ​ ​ 263 ​ ​ ( 3,081 ) ​ ​ — ​ ​ 69,885 Municipal obligations ​ ​ 6,596 ​ ​ — ​ ​ ( 72 ) ​ ​ — ​ ​ 6,524 SBA securities ​ ​ 6,830 ​ ​ — ​ ​ ( 103 ) ​ ​ — ​ ​ 6,727 Total ​ $ 272,558 ​ $ 1,087 ​ $ ( 4,686 ) ​ $ — ​ $ 268,959 ​ 10 Table of Contents The Company did not record a provision for estimated credit losses on any AFS securities for the three months ended March 31, 2026 and 2025.

These unrealized losses relate to changes in market interest rates since acquiring the securities. As management has the intent and ability to hold these securities until maturity or cost recovery, no allowance for credit losses on securities is deemed necessary as of March 31, 2026 and December 31, 2025. ​ Note 4 – Loans Receivable, Allowance for Credit Losses and Credit Quality ​ Loans Held for Sale ​ Loans held for sale to the secondary market are carried at the lower of cost or estimated market value on an individual loan basis. Gains on sales of loans are recognized in the consolidated statements of income at the time of sale. Losses on sales of loans are recognized in the consolidated statements of income when incurred. Interest income is recognized on loans held for sale between the time the loan is funded and the loan is sold. Direct loan origination costs and fees are deferred upon origination and are recognized in the consolidated statements of income on the date of sale. As of March 31, 2026 and December 31, 2025, the Company had $ 64.0 million and $ 66.4 million of consumer loans held for sale, respectively. ​ 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”). Loan origination fees and certain direct origination costs are deferred and amortized as an adjustment of yield using the payment terms required by the loan contract. When loans are sold or repaid, any unamortized fees and costs are recorded to interest income on loans. Interest income on loans is accrued based upon the daily principal amount outstanding except for loans on non-accrual status. For acquired loans with no signs of credit deterioration at acquisition, interest income is also accrued based upon the daily principal amount outstanding, adjusted further by the accretion of any discount or amortization of any premium associated with the loan . ​ 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. 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. 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. 12 Table of Contents Allowance for Credit Losses ​ The 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. Subsequent recoveries of previously charged-off amounts are recorded as increases to the ACL. The provision for credit losses 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 FASB ASC 326 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 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 WARM. ​ In applying future economic forecasts, the Company utilizes a forecast period of up to two years. The Company considers economic forecasts of inflation, national gross domestic product, and unemployment rates sourced from the Federal Open Market Committee’s “Summary of Economic Projections” to inform the model for future loss estimation. ​ Additionally, interest rate forecasts sourced from CME Group’s “FedWatch”, Wells Fargo’s “U.S. Economic Outlook,” and FHN Financial’s “Economic Forecast” publications are used for consideration of rate sensitivity in the model’s loan prepayment speed estimation. Historical loss rates used in the quantitative model are primarily derived using both the Bank’s data and peer bank data obtained from publicly available sources (i.e., federal call reports). The Bank’s peer group is comprised of financial institutions of relatively similar size and in similar markets (i.e., $ 10 billion or less of total assets and headquartered in New England). The peer group used for certain loan segments is a national peer group of financial institutions of relatively similar size, where appropriate. The changes did not have a material impact on the ACL during the year ended December 31, 2025. ​ Management also considers qualitative adjustments when estimating credit losses to take into account the model’s quantitative limitations. ​ Management continually assesses the peer group and related data used to inform the ACL calculation. ​ Qualitative adjustments to quantitative loss factors, either negative or positive, may include considerations of economic conditions including economic forecasts as detailed above, volume and severity of past due loans, value of underlying collateral, experience, depth, and ability of management, and concentrations of credit. ​ The Company made no significant changes to loss factors, assumptions nor qualitative factors within the CECL model during the three months ended March 31, 2026 and 2025. ​ For those loans that do not share similar risk characteristics, the Company evaluates the ACL needs 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 or loan terms differing significantly from other pooled loans. 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 being individually evaluated. 13 Table of Contents 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. ​ The Company’s Troubled Asset Resolution Committee approves the key methodologies and assumptions, as well as the ACL on at least a quarterly basis. While management uses available information at the time of estimation to determine expected credit losses on loans, future changes in the ACL may be necessary based on changes in portfolio composition, portfolio credit quality, and/or economic conditions. In addition, bank regulatory agencies periodically review the Bank’s ACL and may require an increase in the provision for credit losses or the recognition of further loan charge-offs, based on judgments different than those of management. ​ Collateral-dependent Loans – The Company has certain loans for which repayment is dependent upon the operation or sale of collateral, as the borrower is experiencing financial difficulty. The underlying collateral can vary based upon the type of loan. The following provides more detail about the types of collateral that secure collateral-dependent loans: ​ ● Commercial real estate and multifamily loans may be secured by either owner-occupied commercial real estate or non-owner-occupied investment commercial real estate. Typically, owner-occupied commercial real estate loans are secured by office buildings, warehouses, manufacturing facilities, and other commercial and industrial properties occupied by operating companies. Repayment is generally from the cash flows of the business occupying the property. ​ Non-owner-occupied commercial real estate loans are generally secured by office buildings and complexes, retail facilities, multifamily complexes, land under development, industrial properties, as well as other commercial or industrial real estate. ​ ● Commercial and industrial loans may be secured by non-real estate collateral such as accounts receivable, inventory, equipment, or other similar assets. Enterprise value is defined as imputed value for the entire underlying business. To determine an appropriate range of enterprise value, management relies on a standardized set of valuation methodologies that take into account future projected cash flows, market-based multiples, as well as asset values. Valuations involve both quantitative and qualitative considerations and professional judgments concerning differences in financial and operating characteristics in addition to other factors that may impact values over time. ​ ● Residential real estate loans are typically secured by first mortgages, and in some cases could be secured by a second mortgage. ​ ● Home equity lines of credit are generally secured by second mortgages on residential real estate property. ​ ● Consumer loans are generally secured by boat and recreational vehicles, automobiles, solar panels and other personal property. Some consumer loans are unsecured, have no underlying collateral, and would not be considered collateral-dependent. ​ ● Warehouse loans are primarily facility lines to non-bank mortgage origination companies. The underlying collateral of these loans are residential real estate loans. ​ Purchased Credit-Deteriorated (“PCD”) Loans - PCD loans are acquired individual loans (or acquired groups of loans with similar risk characteristics) that, as of the date of acquisition, have experienced a more-than-insignificant deterioration in credit quality, as determined by the Company’s analyses. A PCD loan is recorded at its purchase price plus the ACL expected at the time of acquisition, or “gross up” of the amortized cost basis, if any. Changes in the current estimate of the ACL subsequent to acquisition from the estimated allowance previously recorded are recognized in the income statement as provision for credit losses or recoveries of credit losses in subsequent periods as they arise. 14 Table of Contents Evidence that purchased loans, measured at amortized cost, have more-than-insignificant deterioration in credit quality and, therefore meet the PCD definition, may include past-due status, non-accrual status, risk rating and other standard indicators (i.e., modification due to financial difficulty, charge-offs, bankruptcy). ​ 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. ​ Loans consist of the following as of the dates stated: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ March 31, 2026 ​ ​ ​ ​ December 31, 2025 ​ Amount ​ Percent ​ Amount ​ Percent ​ (Dollars in thousands) ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ One-to-four-family residential $ 1,185,601 ​ 19.06 % ​ $ 1,177,156 ​ 19.64 % Home equity ​ 155,717 ​ 2.50 % ​ ​ 152,602 ​ 2.55 % Total residential real estate ​ 1,341,318 ​ 21.56 % ​ ​ 1,329,758 ​ 22.19 % ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Commercial real estate ​ 1,924,862 ​ 30.95 % ​ ​ 1,924,043 ​ 32.09 % Multi-family residential ​ 538,164 ​ 8.65 % ​ ​ 517,527 ​ 8.63 % Total commercial real estate ​ 2,463,026 ​ 39.60 % ​ ​ 2,441,570 ​ 40.72 % Construction and land development ​ 782,721 ​ 12.58 % ​ ​ 730,573 ​ 12.19 % Commercial and industrial ​ 1,143,086 ​ 18.38 % ​ ​ 1,007,669 ​ 16.81 % Total commercial ​ 4,388,833 ​ 70.56 % ​ ​ 4,179,812 ​ 69.72 % ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Consumer, net of premium/discount ​ 212,923 ​ 3.42 % ​ ​ 203,497 ​ 3.40 % ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Mortgage warehouse ​ 277,191 ​ 4.46 % ​ ​ 280,949 ​ 4.69 % ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Total loans ​ 6,220,265 ​ 100.00 % ​ ​ 5,994,016 ​ 100.00 % Deferred fees, net ​ ( 10,355 ) ​ ​ ​ ​ ​ ( 7,876 ) ​ ​ ​ Allowance for credit losses ​ ( 80,195 ) ​ ​ ​ ​ ​ ( 87,411 ) ​ ​ ​ Net loans $ 6,129,715 ​ ​ ​ ​ $ 5,898,729 ​ ​ ​ ​ Included in the above are approximately $ 466.8 million and $ 404.8 million in loans to borrowers in the cannabis industry at March 31, 2026 and December 31, 2025, respectively.

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. Non-accrual residential real estate and commercial loans are downgraded to a substandard risk rating. ​ 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. ​ 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 all 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. ​ 17 Table of Contents The following table presents the amortized cost of loans receivable by internal risk grade by year of origination as of March 31, 2026.

The Company has one identified reporting segment and assigned goodwill to the banking business reporting segment. ​ An assessment is also required to be performed to the extent relevant events and/or circumstances occur which may indicate it is more-likely-than-not that the fair value of a reporting segment is less than its carrying amount. ​ The Company performed its annual assessment for the banking business as of December 31, 2025. The assessment included a qualitative assessment which indicated that it was more likely than not that the fair value of the reporting unit exceeded the carrying value. Based upon the assessment, it was determined there was no impairment of the Company’s goodwill as of December 31, 2025. ​ The amortization expense of the Company’s other intangible assets was $ 892,000 and $ 37,000 during the three months ended March 31, 2026 and 2025, respectively. ​ The weighted average original amortization period and weighted average remaining useful life of the Company’s other intangible assets is 10.0 years and 9.3 years, respectively. Management performs an assessment of the remaining useful lives of the Company’s intangible assets on a quarterly basis to determine if such lives remain appropriate. ​ The estimated amortization expense for the remaining useful life of the Company’s other intangible assets is as follows (in thousands): ​ ​ ​ ​ Year ​ 2026 ​ $ 2,632 2027 ​ 3,183 2028 ​ 2,841 2029 ​ 2,499 2030 ​ ​ 2,157 2031 and thereafter ​ 5,099 ​ ​ $ 18,411 ​ ​ Note 6 – Employee Benefits ​ 401(k) Plan – 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 eligible to participate in the 401(k) plan. 23 Table of Contents 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 March 31, 2026 and 2025 were $ 1.1 million and $ 688,000 , respectively. ​ 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 determined to freeze benefit accruals and withdraw from the CBERA Plan as of December 31, 2023. The Company withdrew from the Plan in the second quarter of 2024. ​ During the three months ended March 31, 2025, as part of the final CBERA Plan liquidation, the Company contributed an additional $ 1.2 million to the CBERA Plan. ​ Officers’ Deferred Compensation Plan – The Company maintains an unfunded, defined contribution, Non-qualified Deferred Compensation Plan (“Officers’ 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 based upon 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 in the Company’s consolidated balance sheets and approximated $ 2.5 million and $ 2.4 million at March 31, 2026 and December 31, 2025, respectively. The expense under the Officers’ Deferred Comp Plan (recorded in salaries and employee benefits in the consolidated statements of income) approximated $ 88,000 and $ 89,000 for the three months ended March 31, 2026 and 2025, respectively. ​ Deferred Compensation Plans – The Company maintains 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 $ 8.0 million and $ 5.1 million at March 31, 2026 and December 31, 2025, 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 $ 3.8 million and $ 7.2 million as of March 31, 2026 and December 31, 2025, respectively. The expense under this plan (recorded in salaries and employee benefits in the consolidated statements of income) approximated $ 612,000 and $ 832,000 for the three months ended March 31, 2026 and 2025, 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 $ 6.9 million and $ 6.8 million as of March 31, 2026 and December 31, 2025, respectively, and is recorded on the consolidated balance sheets. 24 Table of Contents The expense under this plan (recorded in salaries and employee benefits in the consolidated statements of income) approximated $ 160,000 and $ 162,000 for the three months ended March 31, 2026 and 2025, 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. ​ Employment and Change in Control Agreements – The Company entered into an employment agreement with the Chief Executive Officer that renews for one additional year each January 1 st . During 2025, the Company entered into Change in Control agreements with certain executive officers, 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 original loan was payable in annual installments over 20 years at an interest rate of 8.50 %. During the year ended December 31, 2025, the loan was refinanced into annual installments over the remaining 19 years at an interest rate of 7.50 %. 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 $ 885,000 and $ 783,000 for the three months ended March 31, 2026 and 2025, respectively. ​ The following table presents share information held by the ESOP: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ As of ​ ​ March 31, 2026 ​ December 31, 2025 ​ ​ (Dollars in thousands) Allocated shares ​ ​ 170,823 ​ ​ 170,823 Shares committed to be released ​ ​ 42,121 ​ ​ 170,823 Unallocated shares ​ ​ 3,203,514 ​ ​ 3,074,812 Total shares ​ ​ 3,416,458 ​ ​ 3,416,458 Fair value of unallocated shares ​ $ 67,498 ​ $ 60,943 ​ 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. 25 Table of Contents 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 awards of restricted stock 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 following table presents RSA activity for the periods indicated (dollars in thousands). ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Three Months Ended March 31, 2026 ​ Three Months Ended March 31, 2025 ​ ​ Number of Shares ​ Weighted-Average Grant Date Fair Value Per Share ​ Number of Shares ​ Weighted-Average Grant Date Fair Value Per Share ​ ​ ​ ​ ​ ​ ​ ​ ​ Non-vested balance at beginning of period ​ 1,284,525 $ 16.41 ​ — $ — Granted ​ 283,559 ​ 21.64 ​ — ​ — Vested ​ — ​ — ​ — ​ — Forfeited ​ — ​ — ​ — ​ — Non-vested balance at end of period ​ 1,568,084 $ 17.36 ​ — $ — ​ The following table presents stock-based compensation expense for the periods indicated. ​ ​ ​ ​ ​ ​ ​ ​ ​ Three Months Ended ​ Three Months Ended ​ ​ March 31, 2026 ​ March 31, 2025 ​ ​ (in thousands) Stock-based compensation expense: ​ ​ ​ ​ ​ ​ Restricted stock awards ​ $ 1,443 ​ $ — Total stock-based compensation expense ​ $ 1,443 ​ $ — Related tax benefits recognized in earnings ​ $ — ​ $ — ​ During the three months ended March 31, 2026, the Company granted 283,559 shares of restricted stock with a weighted-average grant date fair value per share of $ 21.64 and recognized $ 1.4 million of stock compensation expense. The Company did no t have any restricted stock activity or recognize any stock compensation expense during the three months ended March 31, 2025. ​ Unrecognized stock compensation expense, which is included in Additional Paid-in Capital on the Consolidated Balance Sheets was $ 22.9 million and $ 18.2 million at March 31, 2026 and December 31, 2025, respectively. ​ ​ Note 7 – 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. ​ 26 Table of Contents 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 March 31, 2026 and December 31, 2025. ​ AFS 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 fair value by calculating a settlement termination value with the counterparty. ​ Assets measured and reported at estimated fair value on a recurring basis are summarized below: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ March 31, 2026 ​ Level 1 ​ Level 2 ​ Level 3 ​ Fair Value Assets: ​ (in thousands) Available-for-sale debt securities: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ U.S. Treasury securities ​ $ 96,321 ​ $ — ​ $ — ​ $ 96,321 U.S. Government agencies ​ ​ — ​ ​ 4,686 ​ ​ — ​ ​ 4,686 Agency mortgage-backed securities ​ ​ — ​ ​ 89,853 ​ ​ — ​ ​ 89,853 Agency collateralized mortgage obligations ​ ​ — ​ ​ 11,387 ​ ​ — ​ ​ 11,387 Corporate bonds ​ ​ — ​ ​ 47,753 ​ ​ 14,244 ​ ​ 61,997 Municipal obligations ​ ​ — ​ ​ 6,540 ​ ​ — ​ ​ 6,540 SBA securities ​ ​ — ​ ​ 6,457 ​ ​ — ​ ​ 6,457 Total available-for-sale debt securities ​ $ 96,321 ​ $ 166,676 ​ $ 14,244 ​ $ 277,241 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Derivative assets ​ $ — ​ $ 20,527 ​ $ — ​ $ 20,527 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Liabilities: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Derivative liabilities ​ $ — ​ $ 21,249 ​ $ — ​ $ 21,249 ​ ​ 27 Table of Contents ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ December 31, 2025 ​ Level 1 ​ Level 2 ​ Level 3 ​ Fair Value Assets: ​ (in thousands) Available-for-sale debt securities: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ U.S. Treasury securities ​ $ 95,783 ​ $ — ​ $ — ​ $ 95,783 U.S. Government agencies ​ ​ — ​ ​ 9,212 ​ ​ — ​ ​ 9,212 Agency mortgage-backed securities ​ ​ — ​ ​ 68,591 ​ ​ — ​ ​ 68,591 Agency collateralized mortgage obligations ​ ​ — ​ ​ 12,237 ​ ​ — ​ ​ 12,237 Corporate bonds ​ ​ — ​ ​ 55,664 ​ ​ 14,221 ​ ​ 69,885 Municipal obligations ​ ​ — ​ ​ 6,524 ​ ​ — ​ ​ 6,524 SBA securities ​ ​ — ​ ​ 6,727 ​ ​ — ​ ​ 6,727 Total available-for-sale debt securities ​ $ 95,783 ​ $ 158,955 ​ $ 14,221 ​ $ 268,959 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Derivative assets ​ $ — ​ $ 23,562 ​ $ — ​ $ 23,562 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Liabilities: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Derivative liabilities ​ $ — ​ $ 22,295 ​ $ — ​ $ 22,295 ​ The Company had no purchases, sales or transfers of Level 3 assets during the three months ended March 31, 2026 and 2025. The changes in Level 3 assets during the three months ended March 31, 2026 and 2025 are attributable to total net gains (losses) included in Other Comprehensive Income on subordinated debentures. ​ The Company may also be required from time to time to measure certain other assets 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. 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. ​ Likewise, values for inventory and accounts receivables collateral are based on financial statement balances or aging reports (Level 3). Fair value adjustments are recorded in the period incurred as provision for credit losses on the consolidated statements of income. ​ Enterprise value is defined as imputed value for the entire underlying business. To determine an appropriate range of enterprise value, management relies on a standardized set of valuation methodologies that take into account future projected cash flows, market-based multiples, as well as asset values. Valuations involve both quantitative and qualitative considerations and professional judgments concerning differences in financial and operating characteristics in addition to other factors that may impact values over time (Level 3). ​ The Company had no liabilities measured at fair value on a non-recurring basis. ​ 28 Table of Contents The following table summarizes assets measured at fair value on a non-recurring basis: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ March 31, 2026 ​ ​ ​ ​ Level 1 ​ ​ ​ Level 2 ​ ​ ​ Level 3 ​ ​ ​ Fair Value ​ ​ (in thousands) Collateral-dependent loans, net of reserve ​ $ — ​ $ — ​ $ 39,632 ​ $ 39,632 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ December 31, 2025 ​ ​ ​ ​ Level 1 ​ ​ ​ Level 2 ​ ​ ​ Level 3 ​ ​ ​ Fair Value ​ ​ (in thousands) Collateral-dependent loans, net of reserve ​ $ — ​ $ — ​ $ 42,041 ​ $ 42,041 ​ For Level 3 assets and liabilities measured at fair value on a nonrecurring basis as of March 31, 2026 and December 31, 2025, 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; industry Earnings Before Interest, Taxes, Depreciation and Amortization multiples ​ 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 March 31, 2026 and December 31, 2025, fair values of loans are estimated on an exit price basis incorporating discounts for credit, liquidity and marketability factors. ​ The following tables present the estimated fair values, related carrying amounts, and valuation level of the financial instruments as of the dates stated: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ March 31, 2026 ​ ​ Carrying ​ Fair ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Amount ​ Value ​ Level 1 ​ Level 2 ​ Level 3 ​ ​ (In thousands) Financial Assets: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Cash and cash equivalents ​ $ 375,357 ​ $ 375,357 ​ $ 375,357 ​ $ — ​ $ — Loans held for sale, at fair value ​ ​ 63,971 ​ ​ 63,971 ​ ​ 63,971 ​ ​ — ​ ​ — Loans receivable, net ​ ​ 6,129,715 ​ ​ 6,207,104 ​ ​ — ​ ​ — ​ ​ 6,207,104 Accrued interest receivable ​ ​ 27,150 ​ ​ 27,150 ​ ​ 27,150 ​ ​ — ​ ​ — Non-public investments ​ ​ 40,738 ​ ​ 40,738 ​ ​ — ​ ​ 23,465 ​ ​ 17,273 BOLI ​ ​ 110,586 ​ ​ 110,586 ​ ​ — ​ ​ 110,586 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Financial Liabilities: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Deposits, other than time deposits ​ $ 3,518,621 ​ $ 3,518,621 ​ $ 3,518,621 ​ $ — ​ $ — Time deposits ​ ​ 2,578,367 ​ ​ 2,578,013 ​ ​ — ​ ​ 2,578,013 ​ ​ — FHLB borrowings ​ ​ 189,701 ​ ​ 186,033 ​ ​ — ​ ​ 186,033 ​ ​ — ​ ​ 29 Table of Contents ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ December 31, 2025 ​ ​ Carrying ​ Fair ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Amount ​ Value ​ Level 1 ​ Level 2 ​ Level 3 ​ ​ (In thousands) Financial Assets: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Cash and cash equivalents ​ $ 407,596 ​ $ 407,596 ​ $ 407,596 ​ $ — ​ $ — Loans held for sale, at fair value ​ ​ 66,447 ​ ​ 66,447 ​ ​ 66,447 ​ ​ — ​ ​ — Loans receivable, net ​ ​ 5,898,729 ​ ​ 5,893,652 ​ ​ — ​ ​ — ​ ​ 5,893,652 Accrued interest receivable ​ ​ 25,390 ​ ​ 25,390 ​ ​ 25,390 ​ ​ — ​ ​ — Non-public investments ​ ​ 33,740 ​ ​ 33,740 ​ ​ — ​ ​ 16,594 ​ ​ 17,146 BOLI ​ ​ 104,335 ​ ​ 104,335 ​ ​ — ​ ​ 104,335 ​ ​ — ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Financial Liabilities: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Deposits, other than time deposits ​ $ 3,348,643 ​ $ 3,348,643 ​ $ 3,348,643 ​ $ — ​ $ — Time deposits ​ ​ 2,504,891 ​ ​ 2,506,499 ​ ​ — ​ ​ 2,506,499 ​ ​ — FHLB borrowings ​ ​ 196,235 ​ ​ 191,970 ​ ​ — ​ ​ 191,970 ​ ​ — ​ ​ Note 8 – 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. 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 March 31, 2026 and December 31, 2025, the maximum potential amount of the Company’s obligation was $ 9.0 million 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. ​ 30 Table of Contents Financial instruments whose contract amounts represents 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 ​ ​ March 31, 2026 ​ December 31, 2025 ​ ​ (In thousands) ​ ​ ​ ​ ​ ​ ​ Commitments to originate loans ​ $ 11,298 ​ $ 45,391 Unadvanced funds on lines of credit ​ ​ 822,843 ​ ​ 742,375 Unadvanced funds on construction loans ​ ​ 380,397 ​ ​ 409,180 Unadvanced funds on mortgage warehouse loans ​ ​ 386,744 ​ ​ — Letters of credit ​ ​ 8,977 ​ ​ 9,013 ​ ​ $ 1,610,259 ​ $ 1,205,959 ​ 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 allowance for credit losses 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 $ 3.3 million as of March 31, 2026 and December 31, 2025. For the three months ended March 31, 2026 and 2025, the Company recorded a release of credit losses on unfunded commitments of $ 54,000 and a provision for credit losses on unfunded commitments of $ 211,000 , respectively. ​ ​ Note 9 – 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. ​ 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 tables reflect 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, included in prepaid expenses and other assets on the consolidated balance sheet. ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ March 31, 2026 ​ ​ ​ ​ ​ ​ Weighted Average Rate ​ ​ ​ ​ ​ Notional ​ Weighted Average ​ Current Rate ​ Current Rate ​ ​ Fair Value ​ Amount ​ Maturity ​ Paid ​ Received ​ ​ Asset (Liability) ​ (in thousands) ​ (in years) ​ ​ ​ ​ ​ ​ (in thousands) Interest rate swaps $ 300,000 ​ 2.8 ​ 3.64 % 3.44 % ​ $ ( 711 ) ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Total $ 300,000 ​ ​ ​ ​ ​ ​ ​ ​ $ ( 711 ) ​ 31 Table of Contents ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ December 31, 2025 ​ ​ ​ ​ ​ ​ Weighted Average Rate ​ ​ ​ ​ ​ Notional ​ Weighted Average ​ Current Rate ​ Current Rate ​ ​ Fair Value ​ Amount ​ Maturity ​ Paid ​ Received ​ ​ Asset (Liability) ​ (in thousands) ​ (in years) ​ ​ ​ ​ ​ ​ (in thousands) Interest rate swaps $ 300,000 ​ 3.5 ​ 3.87 % 3.44 % ​ $ 1,284 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Total $ 300,000 ​ ​ ​ ​ ​ ​ ​ ​ $ 1,284 ​ (1) Asset balances are recorded in prepaid expenses and other assets on the consolidated balance sheets. Liability balances are recorded in accrued expenses and other liabilities on the consolidated balance sheets. ​ 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 the third quarter of 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 OCI and is subsequently reclassified into earnings in the period that the hedged forecasted transaction affects earnings. The Company expects approximately $ 492,000 (pre-tax) to be reclassified as an increase to net interest income from OCI related to the Company’s cash flow hedges in the twelve months following March 31, 2026. ​ This reclassification is due to anticipated payments that will be made and/or received on the swaps based on the forward curve at March 31, 2026. The company had no hedges in place for the quarter ended March 31, 2025. ​ 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 apply hedge accounting. Changes air 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. ​ Risk Participation Agreements (“RPAs”) – 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. ​ 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. ​ 32 Table of Contents The table below presents the number of positions and total notional amount of non-designated hedges and RPAs as of the dates stated: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Total March 31, 2026 ​ ​ Number of Positions ​ Notional Derivatives not designated as hedging instruments: ​ ​ ​ ​ (in thousands) Interest rate products ​ ​ 78 ​ $ 554,191 RPA credit contracts ​ ​ 17 ​ ​ 44,565 Total derivatives not designated as hedging instruments ​ ​ ​ ​ $ 598,756 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Total December 31, 2025 ​ ​ Number of Positions ​ Notional Derivatives not designated as hedging instruments: ​ ​ ​ ​ (in thousands) Interest rate products ​ ​ 75 ​ $ 532,972 RPA credit contracts ​ ​ 17 ​ ​ 44,634 Total derivatives not designated as hedging instruments ​ ​ ​ ​ $ 577,606 ​ Tabular Disclosure of Fair Values of Derivative Instruments on the Consolidated Balance Sheet – 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) March 31, 2026 ​ (in thousands) Derivatives not designated as hedging instruments: ​ ​ ​ ​ ​ ​ Interest rate products ​ $ 20,538 ​ $ 20,538 RPA credit contracts ​ ​ — ​ ​ — Total derivatives not designated as hedging instruments ​ $ 20,538 ​ $ 20,538 ​ ​ ​ ​ ​ ​ ​ December 31, 2025 ​ ​ ​ ​ ​ ​ Derivatives not designated as hedging instruments: ​ ​ ​ ​ ​ ​ Interest rate products ​ $ 22,294 ​ $ 22,294 RPA credit contracts ​ ​ — ​ ​ 1 Total derivatives not designated as hedging instruments ​ $ 22,294 ​ $ 22,295 ​ (1) Recorded in prepaid expenses and other assets on the consolidated balance sheets.

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). The components of other comprehensive income (loss) and related tax effects are as follows for the periods indicated: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ For the Three Months Ended ​ ​ ​ ​ March 31, 2026 ​ ​ ​ March 31, 2025 ​ ​ (In thousands) ​ ​ ​ ​ ​ Tax ​ ​ ​ ​ ​ ​ ​ Tax ​ ​ ​ ​ ​ Pre-Tax ​ (Expense) ​ After-Tax ​ Pre-Tax ​ (Expense) ​ After-Tax ​ ​ Amount ​ Benefit ​ Amount ​ Amount ​ Benefit ​ Amount ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Change in fair value of available-for-sale securities ​ $ ( 1,331 ) ​ $ 330 ​ $ ( 1,001 ) ​ $ 2,291 ​ $ ( 589 ) ​ $ 1,702 Less: Reclassification adjustment for realized gains (losses) in net income ​ ​ — ​ ​ — ​ ​ — ​ ​ — ​ ​ — ​ ​ — Net change in fair value of available-for-sale securities ​ ​ ( 1,331 ) ​ ​ 330 ​ ​ ( 1,001 ) ​ ​ 2,291 ​ ​ ( 589 ) ​ ​ 1,702 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Change in fair value of cash flow hedges ​ ​ ( 1,995 ) ​ ​ 499 ​ ​ ( 1,496 ) ​ ​ — ​ ​ — ​ ​ — Change in fair value of cash flow hedge, net of tax ​ ​ ( 1,995 ) ​ ​ 499 ​ ​ ( 1,496 ) ​ ​ — ​ ​ — ​ ​ — ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Total other comprehensive income (loss) ​ $ ( 3,326 ) ​ $ 829 ​ $ ( 2,497 ) ​ $ 2,291 ​ $ ( 589 ) ​ $ 1,702 ​ The following table presents the components of accumulated other comprehensive loss as of March 31, 2026 and December 31, 2025: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ As of ​ ​ March 31, 2026 ​ December 31, 2025 ​ ​ (In thousands) ​ ​ ​ ​ ​ ​ ​ Net unrealized holding losses on available-for-sale securities, net of tax ​ $ ( 3,638 ) ​ $ ( 2,637 ) Net unrealized (loss) gain on cash flow hedge, net of tax ​ ​ ( 533 ) ​ ​ 964 Unrecognized director pension plan benefits, net of tax ​ ​ ( 1,462 ) ​ ​ ( 1,463 ) Total accumulated other comprehensive loss ​ $ ( 5,633 ) ​ $ ( 3,136 ) ​ ​ ​ Note 11 – Regulatory Capital Requirements ​ The Company is 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. ​ The Company operated under the risk-based framework as of March 31, 2026 and December 31, 2025. ​ 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 March 31, 2026 and December 31, 2025, that the Company and the Bank meet all capital adequacy requirements to which each is subject. ​ 34 Table of Contents As of March 31, 2026 and December 31, 2025, 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 category.

There were no securities that had a dilutive effect during the three months ended March 31, 2025, and therefore the weighted-average common shares outstanding used to calculate both basic and diluted EPS are the same during the three months ended March 31, 2025. Unallocated ESOP shares are not deemed outstanding for earnings per share calculations. ​ For the three months ended March 31, 2026 and 2025, there were no anti-dilutive shares. ​ The table below sets forth our earnings per share for the periods indicated: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ For the Three Months Ended ​ ​ ​ ​ March 31, 2026 ​ ​ ​ March 31, 2025 ​ ​ (Dollars in thousands, except per share data) ​ ​ ​ ​ ​ ​ ​ Net income applicable to common shares ​ $ 14,984 ​ $ 12,655 ​ ​ ​ ​ ​ ​ ​ Average number of common shares outstanding ​ ​ 45,463,892 ​ ​ 42,001,381 Less: average unallocated ESOP shares ​ ​ ( 3,074,812 ) ​ ​ ( 3,245,635 ) Less: average unvested restricted stock awards ​ ​ ( 1,419,332 ) ​ ​ — Average number of common shares outstanding used to calculate basic EPS ​ ​ 40,969,748 ​ ​ 38,755,746 Add: assumed conversion - unvested restricted stock awards ​ ​ 451,254 ​ ​ — Average number of common shares outstanding used to calculate diluted EPS ​ ​ 41,421,002 ​ ​ 38,755,746 ​ ​ ​ ​ ​ ​ ​ Earnings per common share - basic ​ $ 0.37 ​ $ 0.33 Earnings per common share - diluted ​ $ 0.36 ​ $ 0.33 ​ ​ 36 Table of Contents
