Introduction

Beacon Financial Corporation, a Delaware corporation, is the holding company for Beacon Bank & Trust and its subsidiaries and Clarendon Private.

The Company offers a wide range of commercial, business and retail banking services, including a full complement of cash management products, foreign exchange services, on-line and mobile banking services, consumer and residential loans and investment advisory services. Clarendon Private is a registered investment advisor with the SEC. Through Clarendon Private, the Company offers a wide range of wealth management services to individuals, families, endowments and foundations to help these clients meet their long-term financial goals.

As a full-service financial institution with 144 banking offices throughout New England and New York, the Bank and its subsidiaries focus their efforts on developing and deepening long-term banking relationships with qualified customers through a full complement of products, excellent customer service, and strong risk management.

The competition for loans and leases and deposits remains strong, with growth and pricing influenced by the Federal Reserve's interest rate-setting actions. Management's scenario analysis of deposit sensitivity to the current competitive rate environment suggests further deposit mix migration and increased sensitivity to interest rates.

As the interest rate environment resets to a more normal, upward-sloping yield curve with shorter-term interest rates lower than longer term interest rates, management expects the net interest margin to increase modestly. This is due to deposit and wholesale funding costs repricing at lower rates, while loans do not reprice at the same magnitude, as well as the accretions from the purchase accounting marks. If both short- and long-term interest rates fall, net interest income models, using a projected flat balance sheet with stable deposit balances, forecast that a parallel decrease in rates will have a negative impact on

the Company's net interest income, net interest spread, and net interest margin. While the Company's current deposit sensitivity rate is approximately 40%, shifting to a more asset sensitive balance sheet could have additional pressure on interest margins.

As discussed above, changes in interest rates could also precipitate a change in the mix and volume of the Company's deposits and loans. The future operating results of the Company will depend on its ability to maintain or increase the current net interest income, manage credit risk, increase sources of non-interest income, while managing non-interest expenses.

The Company and the Bank are supervised, examined and regulated by the FRB. As a Massachusetts-chartered trust company, Beacon Bank & Trust is subject to supervision, examination and regulation by the Massachusetts Division of Banks. The FDIC insures the Bank's deposits up to $250,000 per depositor.

Executive Overview

Balance Sheet

Total assets decreased $1.0 billion, or 17.1% on an annualized basis, to $22.2 billion as of March 31, 2026 from $23.2 billion as of December 31, 2025. The decrease was primarily driven by the reduction in cash balances due to timing fluctuations in customer payroll deposits. Cash, cash equivalents and available for sale investment securities decreased $0.9 billion, or 96.4% on an annualized basis, to $2.8 billion as of March 31, 2026 from $3.7 billion as of December 31, 2025. This decreased the Company's on balance sheet liquidity from 16.1% of total assets as of December 31, 2025 to 12.7% of total assets as of March 31, 2026.

Total loans and leases decreased $105.4 million, or 2.3% on an annualized basis, to $17.9 billion as of March 31, 2026 from $18.0 billion as of December 31, 2025. The Company's commercial loan portfolios, which are composed of commercial real estate loans and commercial loans and leases, represented 77.9% of total loans and leases as of March 31, 2026 and represented 77.4% of total loans and leases as of December 31, 2025.

The decline in customer deposits was driven largely by seasonal first quarter factors such as tax payments, with additional movement concentrated in a small number of rate‑sensitive, higher‑cost accounts. Core consumer and relationship-based deposits remain stable. Core deposits, which include demand checking, NOW, non-payroll money market and savings accounts, totaled $12.9 billion, or 70.3% of total deposits, as of March 31, 2026, a decrease of $0.2 billion from $13.1 billion, or 67.0% of total deposits, as of December 31, 2025.

Total borrowed funds increased $284.1 million, or 144.2% on an annualized basis, to $1.1 billion as of March 31, 2026 from $0.8 billion as of December 31, 2025.

Asset Quality

Nonperforming assets as of March 31, 2026 totaled $151.2 million, or 0.68% of total assets, compared to $116.7 million, or 0.50% of total assets, as of December 31, 2025. Net charge-offs for the three months ended March 31, 2026 were $13.6 million, or 0.30% of average loans and leases on an annualized basis, compared to $7.6 million, or 0.31% of average loans and leases on an annualized basis, for the three months ended March 31, 2025.

Executive Overview

Balance Sheet

Total assets increased $11.3 billion, or 95.0%, to $23.2 billion as of December 31, 2025 from $11.9 billion as of December 31, 2024. The increase was primarily due to the assets assumed in the Transaction. The Transaction created a $23 billion Northeast franchise by combining Legacy Berkshire’s stable, more rural funding base with Legacy Brookline’s commercial lending focus in metro markets. The highly-complementary geographic footprints had minimal branch overlap ensuring minimal market disruption while also providing business diversification, fee income opportunities and improved competitive positioning. The Transaction also created meaningful near-term cost synergies while positioning the Company to benefit from future economies of scale.

Total loans and leases increased $8.3 billion, or 84.4%, to $18.0 billion as of December 31, 2025 from $9.8 billion as of December 31, 2024. The increase was primarily due to the loans assumed in the Transaction partially offset by the sales of $332.6 million of purchased mortgage loans acquired in the Transaction. The Company's commercial loan portfolios, which are comprised of commercial real estate loans and commercial loans and leases, totaled $14.0 billion, or 77.4% of total loans and leases as of December 31, 2025, an increase of $5.7 billion, or 69.8%, from $8.2 billion, or 84.1% of total loans and leases, as of December 31, 2024.

Total investment securities increased $0.8 billion, or 88.7%, to $1.7 billion as of December 31, 2025 from $0.9 billion as of December 31, 2024, primarily due to investment securities assumed in the Transaction partially offset by the sale of $176.4 million of the Legacy Berkshire's investment portfolio during the third quarter.

Cash and cash equivalents increased $1.5 billion, or 275.5%, to $2.0 billion as of December 31, 2025 from $0.5 billion as of December 31, 2024. The increase was primarily due to cash and equivalents assumed in the Transaction and an increased payroll deposit balance at December 31, 2025.

Total deposits increased $10.6 billion, or 119.2%, to $19.5 billion as of December 31, 2025 from $8.9 billion as of December 31, 2024, primarily due to the deposits assumed in the Transaction. Core deposits, which include demand checking, NOW, non-payroll money market and savings accounts, totaled $13.1 billion, or 67.0% of total deposits, as of December 31, 2025, an increase of $6.9 billion, or 112.6%, from $6.1 billion, or 69.1% of total deposits, as of December 31, 2024. Payroll deposits totaled $1.9 billion as of December 31, 2025, all of which was assumed in the Transaction. Certificate of deposit balances totaled $4.2 billion, or 21.3% of total deposits, as of December 31, 2025, an increase of $2.3 billion, or 120.5%, from $1.9 billion, or 21.2% of total deposits, as of December 31, 2024. Brokered deposit balances totaled $0.4 billion, or 2.1% of total deposits as of December 31, 2025, a decrease of $0.5 billion, or 52.8%, from $0.9 billion, or 9.8% of total deposits, as of December 31, 2024.

Total borrowed funds decreased $731.5 million, or 48.1%, to $788.4 million as of December 31, 2025 from $1.5 billion as of December 31, 2024 as combined liquidity as a result of the Transaction and the increase in deposits allowed for reduction in borrowings.

Asset Quality

Nonperforming assets as of December 31, 2025 totaled $116.7 million, or 0.50% of total assets, compared to $70.5 million, or 0.59% of total assets, as of December 31, 2024. Total net charge-offs for the year ended December 31, 2025 were $37.6 million, or 0.30% of average loans and leases, compared to $28.2 million, or 0.29% of average loans and leases, for the year ended December 31, 2024. The increase of $46.2 million in nonperforming assets was primarily driven by the Transaction.

The ratio of the allowance for loan and lease losses to total loans and leases was 1.40% as of December 31, 2025, compared to 1.28% as of December 31, 2024.

The ratio of the allowance for loan and lease losses to nonaccrual loans and leases was 221.49% as of December 31, 2025, compared to 180.37% as of December 31, 2024.

Capital Strength

The Company is a "well-capitalized" bank holding company as defined in the FRB's Regulation Y. The Company's common equity Tier 1 capital ratio was 10.95% as of December 31, 2025, compared to 10.46% as of December 31, 2024. The Company's Tier 1 leverage ratio was 9.25% as of December 31, 2025, compared to 9.06% as of December 31, 2024. As of December 31, 2025, the Company's Tier 1 risk-based ratio was 11.12%, compared to 10.56% as of December 31, 2024. The Company's total risk-based ratio was 13.01% as of December 31, 2025, compared to 12.42% as of December 31, 2024.

The Company's ratio of stockholders' equity to total assets was 10.75% and 10.26% as of December 31, 2025 and December 31, 2024, respectively. The Company's tangible equity ratio was 8.62% and 8.27% as of December 31, 2025 and December 31, 2024, respectively.

Net Income

For the year ended December 31, 2025, the Company reported net income of $90.3 million, or $1.03 per basic and diluted share, an increase of $21.6 million, or 31.4%, from $68.7 million, or $0.77 per basic and diluted share for the year ended December 31, 2024. The increase in net income is primarily the result of an increase in net interest income of $173.5 million and an increase in non-interest income of $24.3 million, partially offset by an increase in non-interest expense of $147.9 million driven by merger costs, an increase in the provision for credit losses on loans of $19.4 million, and an increase in the provision for income taxes of $8.6 million.

The return on average assets was 0.59% for the year ended December 31, 2025, compared to 0.60% for the year ended December 31, 2024. The return on average stockholders' equity was 5.44% for the year ended December 31, 2025, compared to 5.67% for the year ended December 31, 2024.

Net interest margin was 3.56% for the year ended December 31, 2025, up from 3.06% for the year ended December 31, 2024. The increase in net interest margin is a result of a decrease of 54 basis points in the Company's cost of interest bearing liabilities to 3.05% in 2025 from 3.59% in 2024, and an increase in the yield on interest-earning assets of 4 basis points to 5.87% in 2025 from 5.83% in 2024.

Results for 2025 included a provision for credit losses of $41.4 million, as discussed in the "Allowance for Credit Losses—Allowance for Loan and Lease Losses" section below.

Non-interest income increased $24.3 million to $49.9 million for the year ended December 31, 2025 from $25.6 million for the year ended December 31, 2024. The increase was driven by four months of combined Company activity in 2025.

Table of Contents

Non-interest expense increased $147.9 million to $389.7 million for the year ended December 31, 2025 from $241.9 million for the year ended December 31, 2024. The increase was largely attributable to an increase of $57.5 million in merger and restructuring expense and increases in all other non-interest expense categories for the four months of combined Company activity in 2025.

Critical Accounting Policies and Estimates

The accounting policies described below are considered critical to understanding the Company's financial condition and operating results. Such accounting policies are considered to be especially important because they involve a higher degree of complexity and require management to make difficult and subjective judgments which often require assumptions or estimates about matters that are inherently uncertain. The use of different judgments, assumptions and estimates could result in material differences in the Company's operating results or financial condition.

Allowance for Credit Losses

Description. The allowance for credit losses represents management's estimate of expected losses over the life of the loan and lease portfolio. The allowance for credit losses consists of the allowance for loan and lease losses and reserve for unfunded commitments, which are classified as a contra-asset and liability within other liabilities, respectively, on the consolidated balance sheets. Additions to the allowance for credit losses are made by charges to the provision for credit losses. Losses on loans and leases are deducted from the allowance when all or a portion of a loan or lease is considered uncollectible. The determination of the loans on which full collectability is not reasonably assured, the estimates of the fair value of the underlying collateral, and the assessment of economic and other conditions are subject to assumptions and judgments by management. Valuation allowances could differ materially as a result of changes in, or different interpretations of, these assumptions and judgments.

Management evaluates the adequacy of the allowance on a quarterly basis and reviews its conclusion as to the amount to be established with the Audit Committee and the Board of Directors.

Judgments and Uncertainties. In estimating the allowance for credit losses, the Company relies on models and economic forecasts developed by external parties as the primary driver of the allowance for credit losses. These models and forecasts are based on nationwide sets of data. As a result, the Company has calibrated the output of these models to match the performance of a relevant set of peer institutions during the development dataset in order to make the results more relevant to the Company. Additionally, economic forecasts can change significantly over an economic cycle and have a significant level of uncertainty associated with them. The performance of the models is dependent on the variables used in the models being reasonable proxies for the portfolio’s performance; however, these variables may not capture all sources of risk within the portfolio. As a result, management reviews the results and makes qualitative adjustments to the models to capture limitations of the models as necessary. Such qualitative factors may include adjustments to better capture the risk of specialty lending portfolios, the imprecision associated with the economic forecasts, and the ability of the models to capture emerging risks within the portfolio that may not be represented in the historical dataset. These judgments are thoroughly evaluated through management’s review process, and revised on a quarterly basis to account for changes in the facts and circumstances of the portfolio.

Effect If Actual Results Differ From Assumptions. The allowance for credit losses is a reflection of the Company’s best estimate of loss based on a forecast of future conditions as of a point in time. Conditions in the future may vary from those forecasts, causing realized losses to be either higher or lower than forecasted, which will result in either additional provisions from income or a benefit to income based on the performance of the portfolio.

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. A description of the valuation methodologies used to estimate the fair values of the significant assets acquired and liabilities assumed can be found in Note 2, "Business Combinations" within the notes to the consolidated financial statements.

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.

27

Table of Contents

In November 2025, the FASB issued ASU 2025-08, "Financial Instruments - Credit Losses (Topic 326): Purchased Loans". 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 completed in the third quarter, as permitted under the guidance.

See Note 1, “Basis of Presentation” in the notes to the consolidated financial statements for additional information regarding recent accounting developments.

Non-GAAP Financial Measures and Reconciliation to GAAP

In addition to evaluating the Company’s results of operations in accordance with GAAP, management periodically supplements this evaluation with an analysis of certain non-GAAP financial measures, such as the operating earnings metrics, the return on average tangible assets, return on average tangible equity, the tangible stockholders' equity, tangible equity ratio, tangible book value per share and dividend payout ratio. Management believes that these non-GAAP financial measures provide information useful to investors in understanding the Company’s underlying operating performance and trends, and facilitates comparisons with the performance assessment of financial performance, including non-interest expense control, while the tangible equity ratio and tangible book value per share are used to analyze the relative strength of the Company’s capital position.

The methodologies used by the Company for determining the non-GAAP financial measures discussed above may differ from those used by other financial institutions.

Operating Earnings

Operating earnings exclude the after-tax impact of securities gains, the Day 1 CECL provision and merger and restructuring expense. By excluding such items, the Company's results can be measured and assessed on a more consistent basis from period to period. Items excluded from operating earnings are also excluded when calculating the operating return and operating efficiency ratios.

The following table summarizes the Company's operating earnings and operating earnings per share ("EPS") for the periods indicated:

The following table presents the maturity distribution of the Company's loan portfolio as of December 31, 2025.

The following table presents the distribution of the Company's loans that were due after one year between fixed and variable interest rates as of December 31, 2025.

The Company's loan portfolio consists primarily of first mortgage loans secured by commercial, multi-family and residential real estate properties located in the Company's primary lending area, loans to business entities, including commercial lines of credit, loans to condominium associations and loans and leases used to finance equipment used by small businesses. The Company also provides financing for construction and development projects, home equity and other consumer loans.

The Company employs seasoned commercial lenders and retail bankers who rely on community and business contacts as well as referrals from customers, attorneys and other professionals to generate loans and deposits. Existing borrowers are also an important source of business since many of them have more than one loan outstanding with the Company. The Company's ability to originate loans depends on the strength of the economy, trends in interest rates, and levels of customer demand and market competition.

The Company's current policy is that the total credit exposure to one obligor relationship may not exceed $90.0 million unless approved by the Chief Executive Officer, Chief Credit Officer, or Management Loan Committee. As of December 31, 2025, there was one borrower with commitments over $90.0 million. The total of those commitments was $94.9 million or 0.8% of total loans and commitments as of December 31, 2025. As of December 31, 2024, the Company's maximum credit exposure without the approval of the Credit Committee, a committee of Legacy Brookline's Board of Directors, was $60.0 million and there were four borrowers with loans and commitments over $60.0 million. The total of those loans and commitments was $267.3 million, or 2.3% of total loans and commitments, as of December 31, 2024.

The Company has written underwriting policies to control the inherent risks in loan origination. The policies address approval limits, loan-to-value ratios, appraisal requirements, debt service coverage ratios, loan concentration limits and other matters relevant to loan underwriting.

Commercial Real Estate Loans

The commercial real estate portfolio is comprised of commercial real estate loans, multi-family mortgage loans, and construction loans and is the largest component of the Company's overall loan portfolio, representing 55.5% of total loans and leases outstanding as of December 31, 2025.

Typically, commercial real estate loans are larger in size and involve a greater degree of risk than owner-occupied residential mortgage loans. Loan repayment is usually dependent on the successful operation and management of the properties and the value of the properties securing the loans. Economic conditions can greatly affect cash flows and property values.

A number of factors are considered in originating commercial real estate and multi-family mortgage loans. The qualifications and financial condition of the borrower (including credit history), as well as the potential income generation and the value and condition of the underlying property, are evaluated. When evaluating the qualifications of the borrower, the Company considers the financial resources of the borrower, the borrower's experience in owning or managing similar property and the borrower's payment history with the Company and other financial institutions. Factors considered in evaluating the

Table of Contents

underlying property include the net operating income of the mortgaged premises before debt service and depreciation, the debt service coverage ratio (the ratio of cash flow before debt service to debt service), the use of conservative capitalization rates, and the ratio of the loan amount to the appraised value. Generally, personal guarantees are obtained from commercial real estate loan borrowers.

Commercial real estate and multi-family mortgage loans are typically originated for terms of five to fifteen years with amortization periods of 20 to 30 years. Many of the loans are priced at inception on a fixed-rate basis generally for periods ranging from two to five years with repricing periods for longer-term loans. When possible, prepayment penalties are included in loan covenants on these loans. For commercial customers who are interested in loans with terms longer than five years, the Company offers loan level derivatives to accommodate customer need.

The Company's urban and suburban market area is characterized by a large number of apartment buildings, condominiums and office buildings. As a result, commercial real estate and multi-family mortgage lending has been a significant part of the Company's activities for many years. These types of loans typically generate higher yields, but also involve greater credit risk. Many of the Company's borrowers have more than one multi-family or commercial real estate loan outstanding with the Company.

The commercial real estate portfolio was composed primarily of loans secured by multi-family buildings ($2.3 billion), retail stores ($1.9 billion), industrial properties ($1.3 billion), office buildings ($1.2 billion), mixed-use properties ($491.8 million), lodging services ($556.0 million) and food services ($73.8 million) as of December 31, 2025.

The following table presents the percentage of the Company's commercial real estate loan portfolio by borrower type that is owner and non-owner occupied as of December 31, 2025.

The following table presents the percentage of the Company's commercial real estate loan portfolio by geographic concentration that is owner and non-owner occupied as of December 31, 2025.

Construction and development financing is generally considered to involve a higher degree of risk than long-term financing on improved, occupied real estate and thus has lower concentration limits than do other commercial credit classes. Risk of loss on a construction loan is largely dependent upon the accuracy of the initial estimate of construction costs, the estimated time to sell or rent the completed property at an adequate price or rate of occupancy, and market conditions. If the estimates and projections prove to be inaccurate, the Company may be confronted with a project which, upon completion, has a value that is insufficient to assure full loan repayment.

stabilized cash flow from the completed project. For those loans where the primary source of repayment is from resale of the property, in addition to the normal credit analysis performed for other loans, the Company also analyzes project costs, the attractiveness of the property in relation to the market in which it is located and demand within the market area. For those construction loans where the source of repayment is the stabilized cash flow from the completed project, the Company analyzes not only project costs but also how long it might take to achieve satisfactory occupancy and the reasonableness of projected rental rates in relation to market rental rates.

Commercial Loans

The commercial loan and lease portfolio is comprised of commercial and equipment financing loans and leases representing 21.9% of total loans outstanding as of December 31, 2025.

The commercial loan and lease portfolio is composed primarily of loans in the following sectors: small businesses ($1.4 billion), food services ($411.7 million), rental and leasing services ($380.6 million), manufacturing ($285.3 million), retail ($217.3 million), transportation services ($208.3 million) and recreation services ($150.4 million) as of December 31, 2025.

The following table presents the percentage of the Company's commercial loan portfolio by geographic concentration as of December 31, 2025.

The Company provides commercial banking services to companies in its market area. Product offerings include lines of credit, term loans, letters of credit, deposit services and cash management. These types of credit facilities have as their primary source of repayment cash flows from the operations of a business. Interest rates offered are available on a floating basis tied to the prime rate or a similar index or on a fixed-rate basis referenced on the Federal Home Loan Bank of Boston index.

Credit extensions are made to established businesses on the basis of loan purpose and assessment of capacity to repay as determined by an analysis of their financial statements, the nature of collateral to secure the credit extension and, in most instances, the personal guarantee of the owner of the business as well as industry and general economic conditions.

The Company’s equipment financing divisions focus on market niches in which its lenders have deep experience and industry contacts, and on making loans to customers with business experience. An important part of the Company’s equipment financing loan origination volume comes from equipment manufacturers, distributors, and owner-operated start-ups as well as existing customers that are expanding their operations. The equipment financing portfolio is composed primarily of loans to finance vended-laundry, and to a lesser degree larger industrial laundries, tow trucks, fitness, and convenience/grocery stores. Typically, the loans are priced at a fixed rate of interest and require monthly payments over their 5- to 10-year life. The yields earned on equipment financing loans are higher than those earned on the commercial loans made by the Bank because they involve a higher degree of credit risk. Equipment financing customers are typically small-business owners who operate with limited financial resources and who face greater risks when the economy weakens or unforeseen adverse events arise. Because of these characteristics, personal guarantees of borrowers are usually obtained along with liens on available assets. The size of loan is determined by an analysis of cash flow and other characteristics pertaining to the business and the equipment to be financed, based on detailed revenue and profitability data of similar operations.

Consumer Loans

The consumer loan portfolio is comprised of residential mortgage loans, home equity loans and lines of credit, and other consumer loans representing, 22.6% of total loans outstanding as of December 31, 2025. The Company focuses its mortgage and home equity lending on existing and new customers within its branch networks in its urban and suburban marketplaces in New England and New York.

The Company originates adjustable and fixed rate residential mortgage loans secured by one- to four-family residences. Each residential mortgage loan granted is subject to a satisfactorily completed application, employment verification, credit history and a demonstrated ability to repay the debt. Generally, loans are not made when the loan-to-value ratio exceeds 80%

35

Table of Contents

unless private mortgage insurance is obtained and/or there is a financially strong guarantor. Appraisals are performed by outside independent appraisers.

Underwriting guidelines for home equity loans and lines of credit are similar to those for residential mortgage loans. Home equity loans and lines of credit are limited to no more than 80% of the appraised value of the property securing the loan including the amount of any existing first mortgage liens.

Other consumer loans have historically been a modest part of the Company's loan originations. As of December 31, 2025, other consumer loans equaled $141.4 million, or 0.8% of total loans outstanding.

Asset Quality

Criticized and Classified Assets

The Company's management rates certain loans and leases as OAEM, "substandard" or "doubtful" based on criteria established under banking regulations. These loans and leases are collectively referred to as "criticized" assets. Loans and leases rated OAEM have potential weaknesses that deserve management's close attention. If left uncorrected, these potential weaknesses may result in deterioration of the repayment prospects of the loan or lease at some future date. Loans and leases rated as substandard are inadequately protected by the payment capacity of the obligor or of the collateral pledged, if any. Substandard loans and leases have a well-defined weakness or weaknesses that jeopardize the liquidation of debt and are characterized by the distinct possibility that the Company will sustain some loss if existing deficiencies are not corrected. Loans and leases rated as doubtful have well-defined weaknesses that jeopardize the orderly liquidation of debt and partial loss of principal is likely. As of December 31, 2025, the Company had $683.7 million of total assets that were designated as criticized. This compares to $252.7 million of assets designated as criticized as of December 31, 2024. The increase of $431 million in criticized assets was primarily driven by the Transaction.

Nonperforming Assets

"Nonperforming assets" consist of nonaccrual loans and leases, OREO and other repossessed assets. Under certain circumstances, the Company may restructure the terms of a loan or lease as a concession to a borrower, except for acquired loans and leases which are individually evaluated against expected performance on the date of acquisition. These restructured loans and leases are generally considered "nonperforming loans and leases" until a history of collection of at least six months on the restructured terms of the loan or lease has been established. OREO consists of real estate acquired through foreclosure proceedings and real estate acquired through acceptance of a deed in lieu of foreclosure. Other repossessed assets consist of assets that have been acquired through foreclosure that are not real estate and are included in other assets on the Company's consolidated balance sheets.

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. When a loan is placed on nonaccrual status, interest accruals cease and all previously accrued and uncollected 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 months of performance has been achieved.

In cases where a borrower experiences financial difficulties and the Company makes or reasonably expects to make certain concessionary modifications to contractual terms, the loan is classified as a modified loan. In determining whether a debtor is experiencing financial difficulties, the Company considers, among other factors, if the debtor is in payment default or is likely to be in payment default in the foreseeable future without the modification, 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, or the debtor cannot obtain funds from sources other than the existing creditors at market terms for debt with similar risk characteristics.

As of December 31, 2025, the Company had nonperforming assets of $116.7 million, representing 0.50% of total assets, compared to nonperforming assets of $70.5 million, or 0.59% of total assets as of December 31, 2024. The increase of $46.2 million was primarily driven by the Transaction.

The Company evaluates the underlying collateral of each nonaccrual loan and lease and continues to pursue the collection of interest and principal. Management believes that the current level of nonperforming assets remains manageable relative to the size of the Company's loan and lease portfolio. If economic conditions were to worsen or if the marketplace were to experience prolonged economic stress, it is likely that the level of nonperforming assets would increase, as would the level of charged-off loans.

Past Due and Accruing

As of December 31, 2025, the Company had $37.8 million loans and leases greater than 90 days past due and accruing, compared to $0.8 million as of December 31, 2024.

The following table sets forth information regarding nonperforming assets for the periods indicated:

Allowances for Credit Losses

The allowance for credit losses consists of general and specific allowances and reflects management's estimate of expected loan and lease losses over the life of the loan or lease. Management uses a consistent and systematic process and methodology to evaluate the adequacy of the allowance for credit losses on a quarterly basis. Management continuously evaluates and challenges inputs and assumptions in the allowance for credit losses.

While management evaluates currently available information in establishing the allowance for credit losses, future adjustments to the allowance for loan and lease losses may be necessary if conditions differ substantially from the assumptions used in making the evaluations. Management performs a comprehensive review of the allowance for credit losses on a quarterly

basis. In addition, various regulatory agencies, as an integral part of their examination process, periodically review a financial institution's allowance for credit losses and carrying amounts of other real estate owned. Such agencies may require the financial institution to recognize additions or reductions to the allowance based on their judgments about information available to them at the time of their examination.

The Company’s allowance methodology provides a quantification of probable losses in the portfolio. Under the current methodology, management estimates losses over the life of the loan using reasonable and supportable forecasts. Forecasts, loan data, and model documentation are extensively analyzed and reviewed throughout the quarter to ensure estimated losses are appropriate at quarter end. Qualitative adjustments are applied when model output does not align with management expectations. These adjustments are thoroughly reviewed and documented to provide clarity and a reasonable basis for any deviations from the model. For December 31, 2025, qualitative adjustments were applied to the commercial real estate, commercial, and consumer portfolios resulting in a net addition in total reserves compared to modeled calculations.

The following tables present the changes in the allowance for loans and lease losses by portfolio category for the years ended December 31, 2025, 2024, 2023, 2022, and 2021, respectively.

38

Table of Contents

At December 31, 2025, the allowance for loan and lease losses increased to $252.8 million, or 1.40% of total loans and leases outstanding. This compared to an allowance for loan and lease losses of $125.1 million, or 1.28% of total loans and leases outstanding, as of December 31, 2024.The increase in the allowance for loan and lease losses was primarily due to the Transaction.

Net charge-offs in the loans and leases portfolio for the years ending December 31, 2025 and 2024 were $37.6 million and $24.5 million, respectively. The $13.1 million increase in net charge-offs was primarily driven by net charge-off increases of $7.3 million in commercial loans and $6.3 million in commercial real estate loans, offset by a decrease of $0.5 million in consumer loans. $5.7 million of the increase was related to the Transaction.

Management believes that the allowance for loan and lease losses as of December 31, 2025 is appropriate based on the facts and circumstances discussed further below.

Investment Securities and Restricted Equity Securities

The investment portfolio exists primarily for liquidity purposes, and secondarily as sources of interest and dividend income, interest-rate risk management and tax planning as a counterbalance to loan and deposit flows. Investment securities are utilized as part of the Company's asset/liability management and may be sold in response to, or in anticipation of, factors such as changes in market conditions and interest rates, deposit outflows, liquidity concentrations and regulatory capital requirements.

The investment policy of the Company, which is reviewed and approved by the Board of Directors on an annual basis, specifies the types of investments that are acceptable, required investment ratings by at least one nationally recognized rating agency, concentration limits and duration guidelines. Compliance with the investment policy is monitored on a regular basis. In general, the Company seeks to maintain a high degree of liquidity and targets cash, cash equivalents and investment securities available-for-sale balances between 10% and 14% of total assets.

Cash, cash equivalents, and investment securities increased $2.3 billion, or 159.3%, to $3.7 billion as of December 31, 2025 compared to $1.4 billion as of December 31, 2024. The increase was impacted by the Transaction. Cash, cash equivalents, and investment securities were 16.1% of total assets as of December 31, 2025, compared to 12.1% of total assets at December 31, 2024.

The following table sets forth certain information regarding the amortized cost and market value of the Company's investment securities at the dates indicated:

Total investment securities and restricted equity securities primarily consist of investment securities available-for-sale, stock in the FHLB and stock in the FRB. The total securities portfolio increased $798.0 million, or 81.6% since December 31, 2024. As of December 31, 2025, the total securities portfolio was 7.65% of total assets, compared to 8.22% of total assets as of December 31, 2024.

The fair value of investment securities is based principally on market prices and dealer quotes received from third-party, nationally-recognized pricing services for identical investment securities such as U.S. Treasury and agency securities. The Company's equity securities held-for-trading, if any, are priced this way and are included in Level 1. These prices are validated by comparing the primary pricing source with an alternative pricing source when available. When quoted market prices for identical securities are unavailable, the Company uses market prices provided by independent pricing services based on recent trading activity and other observable information, including but not limited to market interest-rate curves, referenced credit spreads and estimated prepayment speeds where applicable. These investments include certain U.S. and government agency debt securities, municipal and corporate debt securities, GSEs, MBSs and CMOs, trust preferred securities, and equity securities held-for-trading, all of which are included in Level 1, 2 and 3.

Additionally, management reviews changes in fair value from period to period and performs testing to ensure that prices received from the third parties are consistent with their expectation of the market. Changes in the prices obtained from the pricing service are analyzed from month to month, taking into consideration changes in market conditions including changes in mortgage spreads, changes in U.S. Treasury security yields and changes in generic pricing of 15-year and 30-year securities. Additional analysis may include a review of prices provided by other independent parties, a yield analysis, a review of average life changes using Bloomberg analytics and a review of historical pricing for the particular security.

As of December 31, 2025, the fair value of all investment securities available-for-sale was $1.7 billion and carried a total of $27.5 million of net unrealized losses, compared to a fair value of $895.0 million and net unrealized losses of $69.4 million as of December 31, 2024. As of December 31, 2025, $552.9 million, or 32.7%, of the portfolio, had gross unrealized losses of $44.7 million. This compares to $705.3 million, or 78.8%, of the portfolio with gross unrealized losses of $70.2 million as of December 31, 2024. The Company's increased unrealized loss position in 2025 was primarily driven by higher interest rates year over year. In 2024, U.S. Treasury yields rose across the 3-to-10 year part of the curve which negatively impacted the value of the Company's longer duration primarily in the GSE CMOs and GSE MBS security portfolios. For additional discussion on investment securities available-for-sale by security type, see Note 4, "Investment Securities" to the consolidated financial statements.
