Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Financial Statement Presentation	Basis of Financial Statement Presentation The Company's consolidated financial statements have been prepared in conformity with U.S. GAAP as set forth by the FASB in its Accounting Standards Codification and through the rules and interpretive releases of the SEC under the authority of federal securities laws.
Consolidation	The consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. All significant intercompany transactions and balances are eliminated in consolidation.
Use of Estimates	In preparing these consolidated financial statements, management is required to make significant estimates and assumptions that affect the reported amounts of assets, liabilities, income, expenses and disclosure of assets and liabilities. Actual results could differ from those estimates based upon changing conditions, including economic conditions and future events. Material estimates that are particularly susceptible to significant changes in the near-term include the determination of the ACL and the determination of fair market values of assets and liabilities. The judgments used by management in applying these significant estimates may be affected by a further and prolonged deterioration in the economic environment, which may result in changes to future financial results. For example, subsequent evaluations of the loan and lease portfolio, in light of the factors then prevailing, may result in significant changes in the allowance for loan and lease losses in future periods, and the inability to collect outstanding principal may result in increased loan and lease losses.
Reclassification	Reclassification Certain previously reported amounts have been reclassified to conform to the current year's presentation.
Cash and Cash Equivalents	Cash and Cash Equivalents For purposes of reporting asset balances and cash flows, cash and cash equivalents includes cash on hand and due from banks (including cash items in process of clearing), interest-bearing deposits with banks, federal funds sold, money market mutual funds and other short-term investments with original maturities of three months or less. Cash and cash equivalents are held at major institutions and are subject to credit risk to the extent those balances exceed applicable FDIC or Securities Investor Protection Corporation limitations.
Investment Securities	Investment Securities Investment securities, other than those reported as short-term investments, are classified at the time of purchase as "available-for-sale," "held-to-maturity," or "held-for-trading." Classification is periodically re-evaluated for consistency with the Company's goals and objectives. Equity investments in the FHLB of Boston, the Federal Reserve Bank of Boston, and other restricted equities are discussed in more detail in Note 5, "Restricted Equity Securities." Investment Securities Available-for-Sale, Held-to-Maturity, and Held-for-Trading Investment securities for which the Company has the positive intent and ability to hold to maturity are classified as held-to-maturity and carried at amortized cost. As of December 31, 2025 and 2024, the Company did not hold any securities as held-to-maturity. Those investment securities held for indefinite periods of time but not necessarily to maturity are classified as available-for-sale. Investment securities held for indefinite periods of time include investment securities that management intends to use as part of its asset/liability, liquidity, and/or capital management strategies and may be sold in response to changes in interest rates, maturities, asset/liability mix, liquidity needs, regulatory capital needs or other business factors. Investment securities available-for-sale are carried at estimated fair value, primarily obtained from a third-party pricing service, with unrealized gains and losses reported on an after-tax basis in stockholders' equity as accumulated other comprehensive income or loss. Investment securities expected to be held for very short term duration, used for hedging, or are marketable equity securities are typically designated held-for-trading. Held-for-trading securities are carried at estimated fair value principally based on market prices and dealer quotes received from third-party and nationally-recognized pricing services. Gains and losses for held-for-trading are reported on the income statement as gains on investment securities, net. As of December 31, 2025 and 2024, the Company did not hold any securities as held-for-trading. As of December 31, 2025 and 2024, the Company did not make any adjustments to the prices provided by the third-party pricing service. Security transactions are recorded on the trade date. Realized gains and losses are determined using the specific identification method and are recorded in non-interest income. Interest and dividends on securities are recorded using the accrual method. Premiums and discounts on securities are amortized or accreted into interest income using the level-yield method over the remaining period to contractual maturity, adjusted for the effect of actual prepayments in the case of MBSs and CMOs. These estimates of prepayment assumptions are made based upon the actual performance of the underlying security, current interest rates, the general market consensus regarding changes in mortgage interest rates, the contractual repayment terms of the underlying loans, the priority rights of the investors to the cash flows from the mortgage securities and other economic conditions. When differences arise between anticipated prepayments and actual prepayments, the effective yield is recalculated to reflect actual payments to date and anticipated future payments. Unamortized premium or discount is adjusted to the amount that would have existed had the new effective yield been applied since purchase, with a corresponding charge or credit to interest income. Restricted Equity Securities The Company invests in the stock of the FHLB of Boston, the Federal Reserve Bank of Boston, and a small amount of other restricted securities. No ready market exists for these stocks, and they have no quoted market values. The Bank, as a member of the FHLB, is required to maintain investments in the capital stock of the FHLB equal to its membership base investments plus an activity-based investment determined according to the Banks level of outstanding FHLB advances. The Company has also purchased Federal Reserve Bank of Boston stock which is redeemable at par. The Company reviews for impairment of these securities based on the ultimate recoverability of the cost basis in the stock.
Loans	Loans Loans and Leases Loans the Company originates for the portfolio, and for which it has the intent and ability to hold to maturity, are reported at amortized cost, inclusive of deferred loan origination fees and expenses, less unadvanced funds due to borrowers on loans and the allowance for loan and lease losses. Interest income on loans and leases originated for the portfolio is accrued on unpaid principal balances as earned. Loan origination fees and direct loan origination costs are deferred, and the net fee or cost is recognized in interest income using the interest method. Deferred amounts are recognized for fixed-rate loans over the contractual life of the loans and for adjustable-rate loans over the period of time required to adjust the contractual interest rate to a yield approximating a market rate at the origination date. If a loan is prepaid, the unamortized portion of the loan origination costs, including third party referral related costs not subject to rebate from the dealer, is charged to income. Loans and Leases Held-for-Sale Management identifies and designates certain newly originated loans and leases for sale to specific financial institutions, subject to the underwriting criteria of those financial institutions. These loans and leases are held for sale and are carried at the lower of cost or market as determined in the aggregate. Deferred loan fees and costs are included in the determination of the gain or loss on sale. The Company had no loans and leases held-for-sale as of December 31, 2025 and 2024. Nonperforming Loans Nonaccrual Loans Accrual of interest on loans generally is discontinued when contractual payment of principal or interest becomes past due 90 days or, if in management's judgment, reasonable doubt exists as to the full timely collection of interest. Exceptions may be made if the loan has matured and is in the process of renewal or is well-secured and in the process of collection. When a loan is placed on nonaccrual status, interest accruals cease and uncollected accrued interest is reversed and charged against current interest income. Interest payments on nonaccrual loans are generally applied to principal. If collection of the principal is reasonably assured, interest payments are recognized as income on the cash basis. Loans are generally returned to accrual status when principal and interest payments are current, full collectability of principal and interest is reasonably assured and a consistent record of at least six consecutive months of performance has been achieved. Impaired Loans A loan is considered to be impaired when, based on current information and events, it is probable that the Company will be unable to collect all amounts due (both interest and principal) according to the contractual terms of the loan agreement. Smaller-balance, homogeneous loans that are evaluated collectively for impairment, such as residential, home equity and other consumer loans are specifically excluded from the impaired loan portfolio. The Company has defined the population of impaired loans to include nonaccrual loans. When the ultimate collectability of the total principal of an impaired loan or lease is in doubt and the loan is on nonaccrual status, all payments are applied to principal, under the cost recovery method. When the ultimate collectability of the total principal of an impaired loan or lease is not in doubt and the loan or lease is on nonaccrual status, contractual interest is credited to interest income when received, under the cash basis method. The value of an impaired loan is measured based upon the present value of expected future cash flows discounted at the loan's effective interest rate, or the fair value of the collateral if the loan is collateral-dependent and its payment is expected solely based on the underlying collateral. For impaired loans deemed collateral dependent, where impairment is measured using the fair value of the collateral, the Company will either obtain a new appraisal or use another available source of collateral assessment to determine a reasonable estimate of the fair value of the collateral. Interest collected on impaired loans is either applied against principal or reported as income according to management's judgment as to the collectability of principal. If management does not consider a loan ultimately collectible within an acceptable time frame, payments are applied as principal to reduce the loan balance. If full collection of the remaining recorded investment should subsequently occur, interest receipts are recorded as interest income on a cash basis. Loan Modifications In determining whether a debtor is experiencing financial difficulties, the Company considers, among other factors, whether the debtor is in payment default or is likely to be in payment default in the foreseeable future without the modification, if the debtor declared or is in the process of declaring bankruptcy, there is substantial doubt that the debtor will continue as a going concern, the debtor's entity-specific projected cash flows will not be sufficient to service its debt, if the debtor has securities that have been delisted or are in the process of being delisted, or the debtor cannot obtain funds from sources other than the existing creditors at market terms for debt with similar risk characteristics. Disclosable modifications under current guidance include principal forgiveness, interest rate reductions, significant payment delays, maturity extensions, or any combination of the aforementioned modifications. The Company tracks and discloses the performance of these modifications with respect to delinquency and re-modification status. The current guidance also eliminates the requirement to measure the allowance using a DCF methodology, and allows for a portfolio-based methodology for modified loans to troubled borrowers. If the DCF approach is still utilized for individually evaluated loans, the discount rate used must be the modified effective interest rate, rather than the original effective interest rate. Typically, modified loans to troubled borrowers are Substandard credits and are already evaluated for impairment on an individual basis.
Allowance for Credit Losses Methodology	Allowance for Credit Losses Methodology Management has established a methodology to determine the adequacy of the ACL that assesses the risks and losses expected on the loan and lease portfolio and unfunded commitments. Additions to the ACL are made by charges to the provision for credit losses. Losses on loans and leases are charged off against the allowance when all or a portion of a loan or lease is considered uncollectible. Subsequent recoveries on loans previously charged off, if any, are credited to the allowance when realized. To calculate the allowance for loans collectively evaluated, management uses models developed by a third party. The Bank’s core ACL process uses CRE, C&I, and retail lifetime loss rate models (core models) to calculate a lifetime loss rate based on loan attributes and reasonable and supportable economic forecasts. This lifetime loss rate is then applied to exposure at default. The exposure at default considers the current unpaid balance and expected utilization assumptions for unfunded commitments. Key assumptions used in the models include portfolio segmentation, prepayments, and the expected utilization of unfunded commitments, among others. The portfolios are segmented by loan level attributes such as loan type, loan size, date of origination, delinquency status, and risk ratings to create loan pools with similar risk characteristics. Prepayment assumptions are embedded within the models and are based on the same data used for model development and incorporate adjustments for reasonable and supportable forecasts. The historical data used to develop the model, including the observation period vary by model, but all use at least ten years of historical data and capture at least one recessionary period. Expected utilization is based on current utilization and a LEQ factor. LEQ varies by current utilization and provides a reasonable estimate of expected draws and borrower behavior. Assumptions and model inputs are reviewed in accordance with model monitoring practices and as information becomes available. Loans acquired in connection with the Transaction have losses estimated using a historical loss rate model (Legacy Berkshire model) based on the historical performance of various loan segments, which are segmented primarily by FDIC code, estimates of each segment’s weighted average life, and a statistical model to capture the impact of reasonable and supportable economic forecasts on the base loss rates. The ACL estimate for both the Banks core models and Legacy Berkshire model incorporates reasonable and supportable forecasts of various macro-economic variables using multiple probability weighted economic scenarios. For the Bank’s core models, reasonable and supportable economic forecasts and reversion to long-term economic conditions are embedded within the vendor provided economic scenarios applied over the remaining life of the loans. Reversion towards long-term expectations generally begins two to three years from the forecast start date and largely completes within the first five years. For the Legacy Berkshire model, management applies an explicit reasonable and supportable forecast period of seven quarters, using a straight-line reversion method over four quarters, after which economic assumptions revert to long term historical averages. The Bank elected to use multiple economic forecasts in determining the reserve to account for economic uncertainty. The forecasts include various projections of gross domestic product, interest rates, property price indices, and employment measures. Scenario weighting and model parameters are updated to reflect facts and circumstances as of the financial statement date. For the core models, the Bank calibrates expected losses for each model using a scalar, which is determined by examining the loss rates of peer banks that have similar operations and asset bases to the Bank and comparing these peer group loss rates to the model results. As of December 31, 2025, management continued to apply qualitative adjustments to the Company’s models. These adjustments are designed to address model limitations and are generally targeted to specific risks within certain portfolios (e.g., office and specialty vehicle) based on recent collateral valuations and performance trends. Additionally, portfolio level metrics such as delinquency, population of adversely graded loans, non-accruals, etc. are used to inform management’s evaluation of the credit risk in the portfolio and adjustments are made as appropriate. These adjustments included both positive and negative adjustments with a total impact to the provision of $24.8 million at December 31, 2025, of which $5.6 million is related to the Legacy Berkshire portfolio. Management reviews these factors on a quarterly basis as market conditions and segment performance evolve. An ACL on loans individually evaluated for impairment is established when amortized cost basis is greater than the discounted present value of expected future cash flows or, in the case of collateral-dependent loans, when there is an excess of a loan's amortized cost basis over the fair value of its underlying collateral. When loans and leases do not share risk characteristics with other financial assets they are evaluated individually. Individually evaluated loans are reviewed quarterly with adjustments made to the calculated reserve as necessary. Liability for Unfunded Commitments In the ordinary course of business, the Company enters into commitments to extend credit, commercial letters of credit, and standby letters of credit. Such financial instruments are recorded in the financial statements when they become payable. The credit risk associated with these commitments is evaluated in a manner similar to the allowance for loan and lease losses.
Premises and Equipment	Premises and Equipment Premises and equipment are carried at cost less accumulated depreciation and amortization, except for land which is carried at cost. Premises and equipment are depreciated using the straight-line method over the estimated useful life of the assets. Leasehold improvements are amortized using the straight-line method over the shorter of the lease term or the estimated useful life of the improvements. Costs related to internal-use software development projects that provide significant new functionality are capitalized. Internal-use software is software acquired or modified solely to meet the Company's needs and for which there is no plan to market the software externally. Direct and indirect costs associated with the application development stage of internal use software are capitalized until such time that the software is substantially complete and ready for its intended use. Capitalized costs are amortized on a straight-line basis over the remaining estimated life of the software. Computer software and development costs incurred in the preliminary project stage, as well as training and maintenance costs, are expensed as incurred.
Leases	Leases The Company leases certain office space under various noncancellable operating leases as well as certain other assets. These leases have terms ranging from 1 year to over 18 years. Certain leases contain renewal options and escalation clauses which can increase rental expenses based principally on the consumer price index and fair market rental value provisions. Right-of-use lease assets are carried on the balance sheet at amortized cost and corresponding lease liabilities are carried on the balance sheet at present value of the future minimum lease payments, adjusted for any initial direct costs and incentives. All of the Company's current outstanding leases are classified as operating leases.
Bank-Owned Life Insurance	Bank-Owned Life Insurance BOLI represents life insurance on the lives of certain current and former employees who have provided positive consent allowing their employer to be the beneficiary of such policies. The Bank utilizes BOLI as tax-efficient financing for its benefit obligations to its employees, including its retirement obligations and SERPs. Since the Bank is the primary beneficiary of the insurance policies, increases in the cash value of the policies, as well as insurance proceeds received, are recorded in non-interest income and are not subject to income taxes. BOLI is recorded at the cash value of the policies, less any applicable cash surrender charges, and is reflected as an asset in the accompanying consolidated balance sheets. Cash proceeds, if any, are classified as cash flows from investing activities. The Company reviews the financial strength of the insurance carriers prior to the purchase of BOLI to ensure minimum credit ratings of at least investment grade. The financial strength of the carriers is reviewed at least annually, and BOLI with any individual carrier is limited to 10% of the Company's capital. Total BOLI is limited to 25% of the Company's capital.
Goodwill and Other Identified Intangible Assets	Goodwill and Other Identified Intangible Assets Goodwill represents the excess of the cost of an acquisition over the fair value of the net assets acquired. Goodwill and indefinite-lived identified intangible assets are not subject to amortization. Definite-lived identified intangible assets are assets resulting from acquisitions that are being amortized over their estimated useful lives. The recoverability of goodwill and identified intangible assets is evaluated for impairment at least annually. A Company can perform a qualitative assessment of whether it is more likely than not that the fair value of an acquired asset is greater than its carrying amount. If the Company qualitatively concludes that it is more likely than not that the fair value of an acquired asset is greater than its carrying amount, no further testing is necessary. If, however, the Company qualitatively concludes that the fair value of an acquired asset is less than its carrying value, or, if for any other reason the Company determines it to be appropriate, then a quantitative assessment will be performed. If a quantitative analysis were performed, management would select a sample of comparable acquisitions and calculate the control premium associated with each sale. The Company’s market capitalization would then be times by the sampled control premium allowing management to compare the calculated fair value to the Company’s current book value to determine if an adjustment to goodwill is warranted. During the year ended December 31, 2025, the Company wrote off the trade name associated with BankRI in connection with the Bank Mergers. There were no impairment losses relating to other intangible assets recorded during the years ended December 31, 2025 and 2024.
OREO and Other Repossessed Assets	OREO and Other Repossessed Assets OREO and other repossessed assets consists of properties acquired through foreclosure, real estate acquired through acceptance of a deed in lieu of foreclosure and loans determined to be substantively repossessed. Real estate loans that are substantively repossessed include only those loans for which the Company has taken possession of the collateral. OREO and other repossessed assets which consist of vehicles and equipment, if any, are recorded initially at estimated fair value less costs to sell, resulting in a new cost basis. The amount by which the recorded investment in the loan exceeds the fair value (net of estimated cost to sell) of the foreclosed or repossessed asset is charged to the allowance for loan and lease losses. Such evaluations are based on an analysis of individual properties/assets as well as a general assessment of current real estate market conditions. Subsequent declines in the fair value of the foreclosed or repossessed asset below the new cost basis are recorded through the use of a valuation allowance. Subsequent increases in the fair value are recorded as reductions in the allowance, but not below zero. Rental revenue received on foreclosed or repossessed assets is included in other non-interest income, whereas operating expenses and changes in the valuation allowance relating to foreclosed and repossessed assets are included in other non-interest expense. Certain costs used to improve such properties are capitalized. Gains and losses from the sale of OREO and other repossessed assets are reflected in non-interest expense when realized. Together with nonperforming loans, OREO and repossessed assets comprise nonperforming assets.
Derivatives	Derivatives The Company utilizes loan level derivatives which consists of interest rate contracts (swaps, caps and floors), and risk participation agreements as part of the Company's interest-rate risk management strategy for certain assets and liabilities and not for speculative purposes. Based on the Company's intended use for the loan level derivatives at inception, the Company designates the derivative as either an economic hedge of an asset or liability, or a hedging instrument subject to the hedge accounting provisions of FASB ASC Topic 815, "Derivatives and Hedging". These derivatives designated as cash flow hedges involve the receipt of fixed rate amounts from a counterparty in exchange for the Company making variable rate payments. Loan level derivatives and foreign exchange contracts entered into on behalf of our customers are designated as economic hedges and are recorded at fair value within other assets or liabilities. Changes in the fair value of these non hedging derivatives are recorded directly through earnings at each reporting period.
Transfer of Financial Assets	Transfer of Financial Assets Transfers of financial assets are accounted for as sales when control over the assets has been surrendered. Control over transferred assets is deemed to be surrendered when (1) the assets have been isolated from the Company, (2) the transferee obtains the right (free of conditions that constrain it from taking advantage of that right) to pledge or exchange the transferred assets, and (3) the Company does not maintain effective control over the transferred assets through an agreement to repurchase them before their maturity.
Employee Benefits	Employee Benefits Costs related to the Company's 401(k) plan are recognized in current earnings. Costs related to the Company's nonqualified deferred compensation plan, SERPs and postretirement benefits are recognized over the vesting period or the related service periods of the participating employees. Changes in the funded status of postretirement benefits and defined pension plans are recognized through comprehensive income in the year in which changes occur. The fair value of restricted stock awards and stock option grants are determined as of the grant date and are recorded as compensation expense over the period in which the shares of restricted stock awards and stock options vest. Forfeitures are accounted for as they occur.
Fair Value Measurements	Fair Value Measurements ASC 820-10, "Fair Value Measurements and Disclosures," defines fair value as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants. A fair value measurement assumes that the transaction to sell the asset or transfer the liability occurs in the principal market for the asset or liability or, in the absence of a principal market, the most advantageous market for the asset or liability. The price in the principal (or most advantageous) market used to measure the fair value of the asset or liability is not adjusted for transaction costs. An orderly transaction is a transaction that assumes exposure to the market for a period prior to the measurement date to allow for marketing activities that are usual and customary for transactions involving such assets and liabilities. It is not a forced transaction. Market participants are buyers and sellers in the principal market that are independent, knowledgeable, able to transact, and willing to transact. A fair-value hierarchy for valuation inputs that gives the highest priority to quoted prices in active markets for identical assets or liabilities and the lowest priority to unobservable inputs are included in ASC 820. The fair value hierarchy is as follows: Level 1: Inputs are unadjusted quoted prices in active markets for assets and liabilities identical to those reported at fair value. Level 2: Inputs other than quoted prices included within Level 1. Level 2 inputs are observable either directly or indirectly. These inputs might include quoted prices for similar assets or liabilities in active markets, quoted prices for identical or similar assets in markets that are not active, inputs other than quoted prices that are observable for the asset or liability (such as interest rates, volatilities, prepayment speeds, credit risks, etc.) or inputs that are derived principally from or corroborated by market data by correlation or other means. Level 3: Inputs are unobservable inputs for an asset or liability that reflect an entity's own assumptions about the assumptions that market participants would use in pricing the assets or liabilities. These inputs are used to determine fair value only when observable inputs are not available.
Earnings per Common Share	Earnings per Common Share EPS is computed by dividing net income by the weighted average number of shares of common stock outstanding for the applicable period, exclusive of Treasury shares and unvested shares of restricted stock. Diluted EPS is calculated after adjusting the denominator of the basic EPS calculation for the effect of all potential dilutive common shares outstanding during the period. The dilutive effects of options and unvested restricted stock awards are computed using the "treasury stock" method. Management evaluated the "two class" method and concluded that the method did not apply to the Company's EPS calculation.
Income Taxes	Income Taxes Income taxes are accounted for under the asset and liability method. Under this method, deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. Tax positions that are more likely than not to be sustained upon a tax examination are recognized in the Company's financial statements to the extent that the benefit is greater than 50% likely of being recognized. Interest resulting from underpayment of income taxes is classified as income tax expense in the first period the interest would begin accruing according to the provision of the relevant tax law. Penalties resulting from underpayment of income taxes are classified as income tax expense in the period for which the Company claims or expects to claim an uncertain tax position or in the period in which the Company's judgment changes regarding an uncertain tax position. For new ITCs, the Company chose to apply the flow-through method and immediately recognize the ITC benefit in income tax expense, as opposed to deferring.
Business Combinations	Business Combinations Business combinations are generally accounted for under the acquisition method of accounting whereby assets acquired and liabilities assumed in business combinations are recorded at their estimated fair value as of the acquisition date. The determination of fair value may involve the use of internal or third-party valuation specialists to assist in the determination of the fair value of certain assets and liabilities at the acquisition date, including loans and leases and core deposit intangible. The excess of the cost of acquisition over these fair values is recognized as goodwill.
Treasury Stock	Treasury Stock Any shares repurchased under the Company's share repurchase programs were purchased in open-market transactions and are held as treasury stock. Treasury stock also consists of common stock withheld to satisfy federal, state and local income tax withholding requirements for employee restricted stock awards upon vesting. All treasury stock is held at cost.
Segment Reporting	Segment Reporting An operating segment is defined as a component of a business for which separate financial information is available that is evaluated regularly by the CODM in deciding how to allocate resources and evaluate performance. The Company is a bank holding company operating through a single business segment, which derives interest income on loan and lease products the Company offers to customers. The President and Chief Executive Officer of the Company acts as the Company’s CODM. The CODM regularly reviews comprehensive financial information with the reported measures focused on net interest income and net income. This financial information reviewed is consistent with the information presented within the Company’s financial statements. The CODM uses the reported measures of net interest income and net income to assess performance by comparing to and monitoring against budget and prior year results. This information is used to manage resources to drive business and net earnings growth, including investment in key strategic priorities, as well as determine the Company's ability to return capital to shareholders. The Company's banking business provided substantially all of its total revenues and pre-tax income in 2025, 2024 and 2023. Therefore, the Company has determined to be a single segment.
Recent Accounting Developments	Recent Accounting Developments In December 2023, the FASB issued ASU 2023-09, "Income Taxes (Topic 740): Improvements to Income Tax Disclosures" to enhance the annual income tax disclosure requirements. This update is effective for annual periods beginning after December 15, 2024. The Company adopted ASU 2023-09 as of January 1, 2025. The adoption did not have a material impact on the Company's consolidated financial statements. In November 2025, the FASB issued ASU 2025-08, "Financial Instruments - Credit Losses (Topic 326): Purchased Loans" ("ASU 2025-08"). This ASU aligns the initial recognition of the allowance for loan losses on purchased loans between PCD and non‑PCD assets by applying the gross‑up approach previously required only for PCD loans. The Company elected to adopt this ASU effective January 1, 2025, and applied it to the Transaction (as defined below) completed in the third quarter, as permitted under the guidance.

Organization, Consolidation and Presentation of Financial Statements [Abstract]

Basis of Financial Statement Presentation

The Company's consolidated financial statements have been prepared in conformity with U.S. GAAP as set forth by the FASB in its Accounting Standards Codification and through the rules and interpretive releases of the SEC under the authority of federal securities laws.

Consolidation

The consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. All significant intercompany transactions and balances are eliminated in consolidation.

Use of Estimates

In preparing these consolidated financial statements, management is required to make significant estimates and assumptions that affect the reported amounts of assets, liabilities, income, expenses and disclosure of assets and liabilities. Actual results could differ from those estimates based upon changing conditions, including economic conditions and future events. Material estimates that are particularly susceptible to significant changes in the near-term include the determination of the ACL and the determination of fair market values of assets and liabilities.

The judgments used by management in applying these significant estimates may be affected by a further and prolonged deterioration in the economic environment, which may result in changes to future financial results. For example, subsequent evaluations of the loan and lease portfolio, in light of the factors then prevailing, may result in significant changes in the allowance for loan and lease losses in future periods, and the inability to collect outstanding principal may result in increased loan and lease losses.

Reclassification

Certain previously reported amounts have been reclassified to conform to the current year's presentation.

Cash and Cash Equivalents

For purposes of reporting asset balances and cash flows, cash and cash equivalents includes cash on hand and due from banks (including cash items in process of clearing), interest-bearing deposits with banks, federal funds sold, money market mutual funds and other short-term investments with original maturities of three months or less. Cash and cash equivalents are held at major institutions and are subject to credit risk to the extent those balances exceed applicable FDIC or Securities Investor Protection Corporation limitations.

Investment Securities

Investment securities, other than those reported as short-term investments, are classified at the time of purchase as "available-for-sale," "held-to-maturity," or "held-for-trading." Classification is periodically re-evaluated for consistency with the Company's goals and objectives. Equity investments in the FHLB of Boston, the Federal Reserve Bank of Boston, and other restricted equities are discussed in more detail in Note 5, "Restricted Equity Securities."

Investment Securities Available-for-Sale, Held-to-Maturity, and Held-for-Trading

Investment securities for which the Company has the positive intent and ability to hold to maturity are classified as held-to-maturity and carried at amortized cost. As of December 31, 2025 and 2024, the Company did not hold any securities as held-to-maturity. Those investment securities held for indefinite periods of time but not necessarily to maturity are classified as available-for-sale. Investment securities held for indefinite periods of time include investment securities that management intends to use as part of its asset/liability, liquidity, and/or capital management strategies and may be sold in response to changes in interest rates, maturities, asset/liability mix, liquidity needs, regulatory capital needs or other business factors. Investment securities available-for-sale are carried at estimated fair value, primarily obtained from a third-party pricing service, with unrealized gains and losses reported on an after-tax basis in stockholders' equity as accumulated other comprehensive income or loss. Investment securities expected to be held for very short term duration, used for hedging, or are marketable equity securities are typically designated held-for-trading. Held-for-trading securities are carried at estimated fair value principally based on market prices and dealer quotes received from third-party and nationally-recognized pricing services. Gains and losses for held-for-trading are reported on the income statement as gains on investment securities, net. As of December 31, 2025 and 2024, the Company did not hold any securities as held-for-trading. As of December 31, 2025 and 2024, the Company did not make any adjustments to the prices provided by the third-party pricing service.

Security transactions are recorded on the trade date. Realized gains and losses are determined using the specific identification method and are recorded in non-interest income. Interest and dividends on securities are recorded using the accrual method. Premiums and discounts on securities are amortized or accreted into interest income using the level-yield method over the remaining period to contractual maturity, adjusted for the effect of actual prepayments in the case of MBSs and CMOs. These estimates of prepayment assumptions are made based upon the actual performance of the underlying security, current interest rates, the general market consensus regarding changes in mortgage interest rates, the contractual repayment terms of the underlying loans, the priority rights of the investors to the cash flows from the mortgage securities and other economic conditions. When differences arise between anticipated prepayments and actual prepayments, the effective yield is recalculated to reflect actual payments to date and anticipated future payments. Unamortized premium or discount is adjusted to the amount that would have existed had the new effective yield been applied since purchase, with a corresponding charge or credit to interest income.

Restricted Equity Securities

The Company invests in the stock of the FHLB of Boston, the Federal Reserve Bank of Boston, and a small amount of other restricted securities. No ready market exists for these stocks, and they have no quoted market values. The Bank, as a member of the FHLB, is required to maintain investments in the capital stock of the FHLB equal to its membership base investments plus an activity-based investment determined according to the Banks level of outstanding FHLB advances. The Company has also purchased Federal Reserve Bank of Boston stock which is redeemable at par. The Company reviews for impairment of these securities based on the ultimate recoverability of the cost basis in the stock.

Loans

Loans and Leases

Loans the Company originates for the portfolio, and for which it has the intent and ability to hold to maturity, are reported at amortized cost, inclusive of deferred loan origination fees and expenses, less unadvanced funds due to borrowers on loans and the allowance for loan and lease losses.

Interest income on loans and leases originated for the portfolio is accrued on unpaid principal balances as earned. Loan origination fees and direct loan origination costs are deferred, and the net fee or cost is recognized in interest income using the interest method. Deferred amounts are recognized for fixed-rate loans over the contractual life of the loans and for adjustable-rate loans over the period of time required to adjust the contractual interest rate to a yield approximating a market rate at the

origination date. If a loan is prepaid, the unamortized portion of the loan origination costs, including third party referral related costs not subject to rebate from the dealer, is charged to income.

Loans and Leases Held-for-Sale

Management identifies and designates certain newly originated loans and leases for sale to specific financial institutions, subject to the underwriting criteria of those financial institutions. These loans and leases are held for sale and are carried at the lower of cost or market as determined in the aggregate. Deferred loan fees and costs are included in the determination of the gain or loss on sale. The Company had no loans and leases held-for-sale as of December 31, 2025 and 2024.

Nonperforming Loans

Nonaccrual Loans

Accrual of interest on loans generally is discontinued when contractual payment of principal or interest becomes past due 90 days or, if in management's judgment, reasonable doubt exists as to the full timely collection of interest. Exceptions may be made if the loan has matured and is in the process of renewal or is well-secured and in the process of collection. When a loan is placed on nonaccrual status, interest accruals cease and uncollected accrued interest is reversed and charged against current interest income. Interest payments on nonaccrual loans are generally applied to principal. If collection of the principal is reasonably assured, interest payments are recognized as income on the cash basis. Loans are generally returned to accrual status when principal and interest payments are current, full collectability of principal and interest is reasonably assured and a consistent record of at least six consecutive months of performance has been achieved.

Impaired Loans

A loan is considered to be impaired when, based on current information and events, it is probable that the Company will be unable to collect all amounts due (both interest and principal) according to the contractual terms of the loan agreement. Smaller-balance, homogeneous loans that are evaluated collectively for impairment, such as residential, home equity and other consumer loans are specifically excluded from the impaired loan portfolio. The Company has defined the population of impaired loans to include nonaccrual loans.

When the ultimate collectability of the total principal of an impaired loan or lease is in doubt and the loan is on nonaccrual status, all payments are applied to principal, under the cost recovery method. When the ultimate collectability of the total principal of an impaired loan or lease is not in doubt and the loan or lease is on nonaccrual status, contractual interest is credited to interest income when received, under the cash basis method.

The value of an impaired loan is measured based upon the present value of expected future cash flows discounted at the loan's effective interest rate, or the fair value of the collateral if the loan is collateral-dependent and its payment is expected solely based on the underlying collateral. For impaired loans deemed collateral dependent, where impairment is measured using the fair value of the collateral, the Company will either obtain a new appraisal or use another available source of collateral assessment to determine a reasonable estimate of the fair value of the collateral.

Interest collected on impaired loans is either applied against principal or reported as income according to management's judgment as to the collectability of principal. If management does not consider a loan ultimately collectible within an acceptable time frame, payments are applied as principal to reduce the loan balance. If full collection of the remaining recorded investment should subsequently occur, interest receipts are recorded as interest income on a cash basis.

Loan Modifications

In determining whether a debtor is experiencing financial difficulties, the Company considers, among other factors, whether the debtor is in payment default or is likely to be in payment default in the foreseeable future without the modification, if the debtor declared or is in the process of declaring bankruptcy, there is substantial doubt that the debtor will continue as a going concern, the debtor's entity-specific projected cash flows will not be sufficient to service its debt, if the debtor has securities that have been delisted or are in the process of being delisted, or the debtor cannot obtain funds from sources other than the existing creditors at market terms for debt with similar risk characteristics.

Disclosable modifications under current guidance include principal forgiveness, interest rate reductions, significant payment delays, maturity extensions, or any combination of the aforementioned modifications. The Company tracks and discloses the performance of these modifications with respect to delinquency and re-modification status.

The current guidance also eliminates the requirement to measure the allowance using a DCF methodology, and allows for a portfolio-based methodology for modified loans to troubled borrowers. If the DCF approach is still utilized for individually evaluated loans, the discount rate used must be the modified effective interest rate, rather than the original effective interest rate. Typically, modified loans to troubled borrowers are Substandard credits and are already evaluated for impairment on an individual basis.

Allowance for Credit Losses Methodology

Management has established a methodology to determine the adequacy of the ACL that assesses the risks and losses expected on the loan and lease portfolio and unfunded commitments. Additions to the ACL are made by charges to the provision for credit losses. Losses on loans and leases are charged off against the allowance when all or a portion of a loan or lease is considered uncollectible. Subsequent recoveries on loans previously charged off, if any, are credited to the allowance when realized.

To calculate the allowance for loans collectively evaluated, management uses models developed by a third party. The Bank’s core ACL process uses CRE, C&I, and retail lifetime loss rate models (core models) to calculate a lifetime loss rate based on loan attributes and reasonable and supportable economic forecasts. This lifetime loss rate is then applied to exposure at default. The exposure at default considers the current unpaid balance and expected utilization assumptions for unfunded commitments. Key assumptions used in the models include portfolio segmentation, prepayments, and the expected utilization of unfunded commitments, among others. The portfolios are segmented by loan level attributes such as loan type, loan size, date of origination, delinquency status, and risk ratings to create loan pools with similar risk characteristics. Prepayment assumptions are embedded within the models and are based on the same data used for model development and incorporate adjustments for reasonable and supportable forecasts. The historical data used to develop the model, including the observation period vary by model, but all use at least ten years of historical data and capture at least one recessionary period. Expected utilization is based on current utilization and a LEQ factor. LEQ varies by current utilization and provides a reasonable estimate of expected draws and borrower behavior. Assumptions and model inputs are reviewed in accordance with model monitoring practices and as information becomes available.

Loans acquired in connection with the Transaction have losses estimated using a historical loss rate model (Legacy Berkshire model) based on the historical performance of various loan segments, which are segmented primarily by FDIC code, estimates of each segment’s weighted average life, and a statistical model to capture the impact of reasonable and supportable economic forecasts on the base loss rates.

The ACL estimate for both the Banks core models and Legacy Berkshire model incorporates reasonable and supportable forecasts of various macro-economic variables using multiple probability weighted economic scenarios. For the Bank’s core models, reasonable and supportable economic forecasts and reversion to long-term economic conditions are embedded within the vendor provided economic scenarios applied over the remaining life of the loans. Reversion towards long-term expectations generally begins two to three years from the forecast start date and largely completes within the first five years.

For the Legacy Berkshire model, management applies an explicit reasonable and supportable forecast period of seven quarters, using a straight-line reversion method over four quarters, after which economic assumptions revert to long term historical averages. The Bank elected to use multiple economic forecasts in determining the reserve to account for economic uncertainty. The forecasts include various projections of gross domestic product, interest rates, property price indices, and employment measures. Scenario weighting and model parameters are updated to reflect facts and circumstances as of the financial statement date. For the core models, the Bank calibrates expected losses for each model using a scalar, which is determined by examining the loss rates of peer banks that have similar operations and asset bases to the Bank and comparing these peer group loss rates to the model results.

As of December 31, 2025, management continued to apply qualitative adjustments to the Company’s models. These adjustments are designed to address model limitations and are generally targeted to specific risks within certain portfolios (e.g., office and specialty vehicle) based on recent collateral valuations and performance trends. Additionally, portfolio level metrics such as delinquency, population of adversely graded loans, non-accruals, etc. are used to inform management’s evaluation of the credit risk in the portfolio and adjustments are made as appropriate. These adjustments included both positive and negative adjustments with a total impact to the provision of $24.8 million at December 31, 2025, of which $5.6 million is related to the Legacy Berkshire portfolio. Management reviews these factors on a quarterly basis as market conditions and segment performance evolve.

An ACL on loans individually evaluated for impairment is established when amortized cost basis is greater than the discounted present value of expected future cash flows or, in the case of collateral-dependent loans, when there is an excess of a loan's amortized cost basis over the fair value of its underlying collateral. When loans and leases do not share risk characteristics with other financial assets they are evaluated individually. Individually evaluated loans are reviewed quarterly with adjustments made to the calculated reserve as necessary.

Liability for Unfunded Commitments

In the ordinary course of business, the Company enters into commitments to extend credit, commercial letters of credit, and standby letters of credit. Such financial instruments are recorded in the financial statements when they become payable. The credit risk associated with these commitments is evaluated in a manner similar to the allowance for loan and lease losses.

Premises and Equipment

Premises and equipment are carried at cost less accumulated depreciation and amortization, except for land which is carried at cost. Premises and equipment are depreciated using the straight-line method over the estimated useful life of the assets. Leasehold improvements are amortized using the straight-line method over the shorter of the lease term or the estimated useful life of the improvements.

Costs related to internal-use software development projects that provide significant new functionality are capitalized. Internal-use software is software acquired or modified solely to meet the Company's needs and for which there is no plan to market the software externally. Direct and indirect costs associated with the application development stage of internal use software are capitalized until such time that the software is substantially complete and ready for its intended use. Capitalized costs are amortized on a straight-line basis over the remaining estimated life of the software. Computer software and development costs incurred in the preliminary project stage, as well as training and maintenance costs, are expensed as incurred.

Leases

The Company leases certain office space under various noncancellable operating leases as well as certain other assets. These leases have terms ranging from 1 year to over 18 years. Certain leases contain renewal options and escalation clauses which can increase rental expenses based principally on the consumer price index and fair market rental value provisions. Right-of-use lease assets are carried on the balance sheet at amortized cost and corresponding lease liabilities are carried on the balance sheet at present value of the future minimum lease payments, adjusted for any initial direct costs and incentives. All of the Company's current outstanding leases are classified as operating leases.

Bank-Owned Life Insurance

BOLI represents life insurance on the lives of certain current and former employees who have provided positive consent allowing their employer to be the beneficiary of such policies. The Bank utilizes BOLI as tax-efficient financing for its benefit obligations to its employees, including its retirement obligations and SERPs.

Since the Bank is the primary beneficiary of the insurance policies, increases in the cash value of the policies, as well as insurance proceeds received, are recorded in non-interest income and are not subject to income taxes. BOLI is recorded at the cash value of the policies, less any applicable cash surrender charges, and is reflected as an asset in the accompanying consolidated balance sheets. Cash proceeds, if any, are classified as cash flows from investing activities.

The Company reviews the financial strength of the insurance carriers prior to the purchase of BOLI to ensure minimum credit ratings of at least investment grade. The financial strength of the carriers is reviewed at least annually, and BOLI with any individual carrier is limited to 10% of the Company's capital. Total BOLI is limited to 25% of the Company's capital.

Goodwill and Other Identified Intangible Assets

Goodwill represents the excess of the cost of an acquisition over the fair value of the net assets acquired. Goodwill and indefinite-lived identified intangible assets are not subject to amortization. Definite-lived identified intangible assets are assets resulting from acquisitions that are being amortized over their estimated useful lives. The recoverability of goodwill and identified intangible assets is evaluated for impairment at least annually. A Company can perform a qualitative assessment of whether it is more likely than not that the fair value of an acquired asset is greater than its carrying amount. If the Company qualitatively concludes that it is more likely than not that the fair value of an acquired asset is greater than its carrying amount, no further testing is necessary. If, however, the Company qualitatively concludes that the fair value of an acquired asset is less

than its carrying value, or, if for any other reason the Company determines it to be appropriate, then a quantitative assessment will be performed. If a quantitative analysis were performed, management would select a sample of comparable acquisitions and calculate the control premium associated with each sale. The Company’s market capitalization would then be times by the sampled control premium allowing management to compare the calculated fair value to the Company’s current book value to determine if an adjustment to goodwill is warranted. During the year ended December 31, 2025, the Company wrote off the trade name associated with BankRI in connection with the Bank Mergers. There were no impairment losses relating to other intangible assets recorded during the years ended December 31, 2025 and 2024.

OREO and Other Repossessed Assets

OREO and other repossessed assets consists of properties acquired through foreclosure, real estate acquired through acceptance of a deed in lieu of foreclosure and loans determined to be substantively repossessed. Real estate loans that are substantively repossessed include only those loans for which the Company has taken possession of the collateral. OREO and other repossessed assets which consist of vehicles and equipment, if any, are recorded initially at estimated fair value less costs to sell, resulting in a new cost basis. The amount by which the recorded investment in the loan exceeds the fair value (net of estimated cost to sell) of the foreclosed or repossessed asset is charged to the allowance for loan and lease losses. Such evaluations are based on an analysis of individual properties/assets as well as a general assessment of current real estate market conditions. Subsequent declines in the fair value of the foreclosed or repossessed asset below the new cost basis are recorded through the use of a valuation allowance. Subsequent increases in the fair value are recorded as reductions in the allowance, but not below zero. Rental revenue received on foreclosed or repossessed assets is included in other non-interest income, whereas operating expenses and changes in the valuation allowance relating to foreclosed and repossessed assets are included in other non-interest expense. Certain costs used to improve such properties are capitalized. Gains and losses from the sale of OREO and other repossessed assets are reflected in non-interest expense when realized. Together with nonperforming loans, OREO and repossessed assets comprise nonperforming assets.

Derivatives

The Company utilizes loan level derivatives which consists of interest rate contracts (swaps, caps and floors), and risk participation agreements as part of the Company's interest-rate risk management strategy for certain assets and liabilities and not for speculative purposes. Based on the Company's intended use for the loan level derivatives at inception, the Company designates the derivative as either an economic hedge of an asset or liability, or a hedging instrument subject to the hedge accounting provisions of FASB ASC Topic 815, "Derivatives and Hedging". These derivatives designated as cash flow hedges involve the receipt of fixed rate amounts from a counterparty in exchange for the Company making variable rate payments.

Loan level derivatives and foreign exchange contracts entered into on behalf of our customers are designated as economic hedges and are recorded at fair value within other assets or liabilities. Changes in the fair value of these non hedging derivatives are recorded directly through earnings at each reporting period.

Transfer of Financial Assets

Transfers of financial assets are accounted for as sales when control over the assets has been surrendered. Control over transferred assets is deemed to be surrendered when (1) the assets have been isolated from the Company, (2) the transferee obtains the right (free of conditions that constrain it from taking advantage of that right) to pledge or exchange the transferred assets, and (3) the Company does not maintain effective control over the transferred assets through an agreement to repurchase them before their maturity.

Employee Benefits

Costs related to the Company's 401(k) plan are recognized in current earnings. Costs related to the Company's nonqualified deferred compensation plan, SERPs and postretirement benefits are recognized over the vesting period or the related service periods of the participating employees. Changes in the funded status of postretirement benefits and defined pension plans are recognized through comprehensive income in the year in which changes occur.

The fair value of restricted stock awards and stock option grants are determined as of the grant date and are recorded as compensation expense over the period in which the shares of restricted stock awards and stock options vest. Forfeitures are accounted for as they occur.

Fair Value Measurements

ASC 820-10, "Fair Value Measurements and Disclosures," defines fair value as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants. A fair value measurement assumes that the transaction to sell the asset or transfer the liability occurs in the principal market for the asset or liability or, in the absence of a principal market, the most advantageous market for the asset or liability. The price in the principal (or most advantageous) market used to measure the fair value of the asset or liability is not adjusted for transaction costs. An orderly transaction is a transaction that assumes exposure to the market for a period prior to the measurement date to allow for marketing activities that are usual and customary for transactions involving such assets and liabilities. It is not a forced transaction. Market participants are buyers and sellers in the principal market that are independent, knowledgeable, able to transact, and willing to transact.

A fair-value hierarchy for valuation inputs that gives the highest priority to quoted prices in active markets for identical assets or liabilities and the lowest priority to unobservable inputs are included in ASC 820. The fair value hierarchy is as follows:

Level 1: Inputs are unadjusted quoted prices in active markets for assets and liabilities identical to those reported at fair value.

Level 2: Inputs other than quoted prices included within Level 1. Level 2 inputs are observable either directly or indirectly. These inputs might include quoted prices for similar assets or liabilities in active markets, quoted prices for identical or similar assets in markets that are not active, inputs other than quoted prices that are observable for the asset or liability (such as interest rates, volatilities, prepayment speeds, credit risks, etc.) or inputs that are derived principally from or corroborated by market data by correlation or other means.

Level 3: Inputs are unobservable inputs for an asset or liability that reflect an entity's own assumptions about the assumptions that market participants would use in pricing the assets or liabilities. These inputs are used to determine fair value only when observable inputs are not available.

Earnings per Common Share

EPS is computed by dividing net income by the weighted average number of shares of common stock outstanding for the applicable period, exclusive of Treasury shares and unvested shares of restricted stock. Diluted EPS is calculated after adjusting the denominator of the basic EPS calculation for the effect of all potential dilutive common shares outstanding during the period. The dilutive effects of options and unvested restricted stock awards are computed using the "treasury stock" method. Management evaluated the "two class" method and concluded that the method did not apply to the Company's EPS calculation.

Income Taxes

Income taxes are accounted for under the asset and liability method. Under this method, deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases.

Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date.

Tax positions that are more likely than not to be sustained upon a tax examination are recognized in the Company's financial statements to the extent that the benefit is greater than 50% likely of being recognized. Interest resulting from underpayment of income taxes is classified as income tax expense in the first period the interest would begin accruing according to the provision of the relevant tax law. Penalties resulting from underpayment of income taxes are classified as income tax expense in the period for which the Company claims or expects to claim an uncertain tax position or in the period in which the Company's judgment changes regarding an uncertain tax position.

For new ITCs, the Company chose to apply the flow-through method and immediately recognize the ITC benefit in income tax expense, as opposed to deferring.

Business Combinations

Business combinations are generally accounted for under the acquisition method of accounting whereby assets acquired and liabilities assumed in business combinations are recorded at their estimated fair value as of the acquisition date. The determination of fair value may involve the use of internal or third-party valuation specialists to assist in the determination of the fair value of certain assets and liabilities at the acquisition date, including loans and leases and core deposit intangible. The excess of the cost of acquisition over these fair values is recognized as goodwill.

Treasury Stock

Any shares repurchased under the Company's share repurchase programs were purchased in open-market transactions and are held as treasury stock. Treasury stock also consists of common stock withheld to satisfy federal, state and local income tax withholding requirements for employee restricted stock awards upon vesting. All treasury stock is held at cost.

Segment Reporting

An operating segment is defined as a component of a business for which separate financial information is available that is evaluated regularly by the CODM in deciding how to allocate resources and evaluate performance.

The Company is a bank holding company operating through a single business segment, which derives interest income on loan and lease products the Company offers to customers.

The President and Chief Executive Officer of the Company acts as the Company’s CODM. The CODM regularly reviews comprehensive financial information with the reported measures focused on net interest income and net income. This financial information reviewed is consistent with the information presented within the Company’s financial statements.

The CODM uses the reported measures of net interest income and net income to assess performance by comparing to and monitoring against budget and prior year results. This information is used to manage resources to drive business and net earnings growth, including investment in key strategic priorities, as well as determine the Company's ability to return capital to shareholders.

The Company's banking business provided substantially all of its total revenues and pre-tax income in 2025, 2024 and 2023. Therefore, the Company has determined to be a single segment.

Recent Accounting Developments

In December 2023, the FASB issued ASU 2023-09, "Income Taxes (Topic 740): Improvements to Income Tax Disclosures" to enhance the annual income tax disclosure requirements. This update is effective for annual periods beginning after December 15, 2024. The Company adopted ASU 2023-09 as of January 1, 2025. The adoption did not have a material impact on the Company's consolidated financial statements.

In November 2025, the FASB issued ASU 2025-08, "Financial Instruments - Credit Losses (Topic 326): Purchased Loans" ("ASU 2025-08"). This ASU aligns the initial recognition of the allowance for loan losses on purchased loans between PCD and non‑PCD assets by applying the gross‑up approach previously required only for PCD loans. The Company elected to adopt this ASU effective January 1, 2025, and applied it to the Transaction (as defined below) completed in the third quarter, as permitted under the guidance.
