1. Corporate Structure and Nature of Operations; Basis of Presentation

Corporate Structure and Nature of Operations

Eastern Bankshares, Inc., a Massachusetts corporation (the “Company”), is a bank holding company. Through its wholly-owned subsidiary, Eastern Bank (the “Bank”), the Company provides a variety of banking services and trust and investment services, through its full-service bank branches, located primarily in eastern Massachusetts, and southern and coastal New Hampshire.

The activities of the Company are subject to the regulatory supervision of the Board of Governors of the Federal Reserve System (“Federal Reserve”). The activities of the Bank are subject to the regulatory supervision of the Massachusetts Commissioner of Banks, the Federal Deposit Insurance Corporation (“FDIC”) and the Consumer Financial Protection Bureau (“CFPB”). The Company and the activities of the Bank and its subsidiaries are also subject to various Massachusetts, New Hampshire and Rhode Island business, banking and trust-related regulations.

Basis of Presentation

The Company’s Consolidated Financial Statements have been prepared in conformity with accounting principles generally accepted in the United States (“GAAP”) as set forth by the Financial Accounting Standards Board (“FASB”) and its Accounting Standards Codification (“ASC”) and Accounting Standards Updates (“ASU”) as well as the rules and interpretive releases of the U.S. Securities and Exchange Commission (“SEC”) under the authority of federal securities laws.

The Consolidated Financial Statements include the accounts of the Company, its wholly-owned subsidiaries and entities in which it holds a controlling financial interest through being the primary beneficiary or through holding a majority of the voting interest. All intercompany accounts and transactions have been eliminated in consolidation.

Certain previously reported amounts have been reclassified to conform to the current period’s presentation which includes:

•reclassification of escrow deposits of borrowers to savings accounts and the related interest expense from interest on borrowings to interest on deposits; and

•combination of certain credit card income balances previously included in other noninterest income and debit card processing fees into a new financial statement line item titled “card income.”

The accompanying Consolidated Balance Sheet as of March 31, 2025, the Consolidated Statements of Income and Comprehensive Income and of Changes in Shareholders’ Equity for the three months ended March 31, 2025 and 2024 and Statements of Cash Flows for the three months ended March 31, 2025 and 2024 are unaudited. The Consolidated Balance Sheet as of December 31, 2024 was derived from the Audited Consolidated Financial Statements as of that date. The interim Consolidated Financial Statements and the accompanying notes should be read in conjunction with the annual Consolidated Financial Statements and the accompanying notes contained within the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2024 (“2024 Form 10-K”), as filed with the SEC. In the opinion of management, the Company’s Consolidated Financial Statements reflect all adjustments, which include only normal recurring adjustments, necessary for a fair statement of the results of operations for the periods presented. The results for the three months ended March 31, 2025 are not necessarily indicative of results to be expected for the year ending December 31, 2025, any other interim period, or any future year or period.

2. Summary of Significant Accounting Policies

The following describes the Company’s use of estimates as well as relevant accounting pronouncements that were recently issued but not yet adopted as of March 31, 2025 and those that were adopted during the three months ended March 31, 2025. For a full discussion of significant accounting policies, refer to the Notes to the Consolidated Financial Statements included within the Company’s 2024 Form 10-K.

Use of Estimates

In preparing the Consolidated Financial Statements in conformity with GAAP, management is required to make estimates and assumptions that affect the reported amounts of assets and liabilities as of the date of the balance sheets and income and expenses for the periods reported. Actual results could differ from those estimates based on changing conditions, including economic conditions and future events. Material estimates that are particularly susceptible to change relate to the determination of the allowance for credit losses, valuation and fair value measurements, the liabilities for benefit obligations (particularly pensions), the provision for income taxes and impairment of goodwill and other intangibles.

Recent Accounting Pronouncements

Relevant standards that were recently issued but not yet adopted as of March 31, 2025:

In October 2023, the FASB issued ASU 2023-06, Disclosure Improvements–Codification Amendments in Response to the SEC’s Disclosure Update and Simplification Initiative (“ASU 2023-06”). The amendments in this update modify the disclosure or presentation requirements for a variety of topics in the codification. Certain amendments represent clarifications to or technical corrections of the current requirements. The following is a summary of the topics included in the update and which pertain to the Company:

1. Statement of cash flows (Topic 230): Requires an accounting policy disclosure in annual periods of where cash flows associated with derivative instruments and their related gains and loses are presented in the statement of cash flows;

2. Accounting changes and error corrections (Topic 250): Requires that when there has been a change in the reporting entity, the entity disclose any material prior-period adjustment and the effect of the adjustment on retained earnings in interim financial statements;

3. Earnings per share (Topic 260): Requires disclosure of the methods used in the diluted earnings-per-share computation for each dilutive security and clarifies that certain disclosures should be made during interim periods, and amends illustrative guidance to illustrate disclosure of the methods used in the diluted earnings per share computation;

4. Commitments (Topic 440): Requires disclosure of assets mortgaged, pledged, or otherwise subject to lien and the obligations collateralized; and

5. Debt (Topic 470): Requires disclosure of amounts and terms of unused lines of credit and unfunded commitments and the weighted-average interest rate on outstanding short-term borrowings.

For public business entities, the amendments in ASU 2023-06 are effective on the date which the SEC’s removal of that related disclosure from Regulation S-X or Regulation S-K becomes effective. If by June 30, 2027, the SEC has not removed the applicable requirement from Regulation S-X or Regulation S-K, the pending content of the related amendment will be removed from the codification and will not become effective for any entity. Early adoption is not permitted and the amendments are required to be applied on a prospective basis. The Company expects the adoption of this standard will not have a material impact on its Consolidated Financial Statements.

In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures. The amendments in this update are intended to improve income tax disclosure requirements, primarily through enhanced disclosures related to the existing requirements to disclose a rate reconciliation, income taxes paid and certain other required disclosures. Specifically, the amendments in this update:

1. Require that a public entity disclose, on an annual basis: (1) specific categories in the rate reconciliation and (2) additional information for reconciling items that meet a quantitative threshold. The update requires disclosure of such reconciling items according to requirements indicated in the update.

2. Require that all entities disclose certain disaggregated information regarding income taxes paid.

3. Require that all entities disclose certain disaggregated information regarding income tax expense.

4. Eliminate the requirement to: (1) disclose the nature and estimate of the range of reasonably possible changes in the unrecognized tax benefits balance in the next 12 months or (2) make a statement that an estimate of the range cannot be made.

5. Remove the requirement to disclose the cumulative amount of each type of temporary difference when a deferred tax liability is not recognized because of exceptions to comprehensive recognition of deferred taxes related to subsidiaries and corporate joint ventures.

For public business entities, the amendments in ASU 2023-09 are effective for annual periods beginning after December 15, 2024. Adoption should be done on a prospective basis and retrospective application is permitted.

In November 2024, the FASB issued ASU 2024-03, Income Statement–Reporting Comprehensive Income–Expense Disaggregation Disclosures (Subtopic 220-40). The amendments in this update require disclosure, in the notes to the financial statements, of specified information about certain costs and expenses. The amendments require that at each interim and annual reporting period an entity:

1. Disclose the amounts of (a) purchases of inventory, (b) employee compensation, (c) depreciation, (d) intangible asset amortization, and (e) depreciation, depletion, and amortization recognized as part of oil and gas-producing activities

(or other amounts of depletion expense) included in each relevant expense caption. A relevant expense caption is an expense caption presented on the face of the income statement within continuing operations that contains any of the expense categories listed in (a)–(e).

2. Include certain amounts that are already required to be disclosed under current GAAP in the same disclosure as the other disaggregation requirements.

3. Disclose a qualitative description of the amounts remaining in relevant expense captions that are not separately disaggregated quantitatively.

4. Disclose the total amount of selling expenses and, in annual reporting periods, an entity’s definition of selling expenses.

For public business entities, the amendments in ASU 2024-03 are effective for annual periods beginning after December 15, 2026 and interim periods beginning after December 15, 2027. Early adoption is permitted. The amendments in this update are to be applied either (1) prospectively to financial statements issued for reporting periods after the effective date of this update or (2) retrospectively to any or all prior periods presented in the financial statements.

No standards were adopted during the three months ended March 31, 2025.

3. Securities

Available for Sale Securities

The amortized cost, gross unrealized gains and losses, allowance for credit losses (“ACL”) and fair value of available for sale (“AFS”) securities as of the dates indicated were as follows:

The Company didnot record a provision for credit losses on any AFS securities for either the three months ended March 31, 2025 or 2024. Accrued interest receivable on AFS securities totaled $13.0 million and $8.9 million as of March 31, 2025 and December 31, 2024, respectively, and is included within other assets on the Consolidated Balance Sheets. The Company didnot record any write-offs of accrued interest receivable on AFS securities during either the three months ended March 31, 2025 or 2024. No AFS securities held by the Company were delinquent on contractual payments as of March 31,

2025 or December 31, 2024, nor were any AFS securities placed on non-accrual status during the three- and twelve-month periods then ended.

The following table summarizes gross realized gains and losses from sales of AFS securities for the periods indicated:

Information pertaining to AFS securities with gross unrealized losses as of March 31, 2025 and December 31, 2024, for which the Company did not recognize a provision for credit losses under the current expected credit loss methodology (“CECL”), aggregated by investment category and length of time that individual securities had been in a continuous loss position, is as follows:

The Company does not intend to sell these investments and has determined based upon available evidence that it is more-likely-than-not that the Company will not be required to sell each security before the expected recovery of its amortized cost basis. As a result, the Company did not recognize an ACL on these investments as of either March 31, 2025 or December 31, 2024.

The causes of the impairments listed in the tables above by category are as follows as of March 31, 2025 and December 31, 2024:

•Government-sponsored mortgage-backed securities, U.S. Agency bonds and U.S. Treasury securities – The securities with unrealized losses in these portfolios have contractual terms that generally do not permit the issuer to settle the security at a price less than the current par value of the investment. The decline in market value of these securities is attributable to changes in interest rates and not credit quality. Additionally, these securities are implicitly guaranteed by the U.S. government or one of its agencies.

•State and municipal bonds and obligations – The securities with unrealized losses in this portfolio have contractual terms that generally do not permit the issuer to settle the security at a price less than the current par value of the investment. The decline in market value of these securities is attributable to changes in interest rates and not credit quality

Held to Maturity Securities

The amortized cost, gross unrealized gains and losses, allowance for credit losses and fair value of held to maturity (“HTM”) securities as of the dates indicated were as follows:

The Company didnot record a provision for estimated credit losses on any HTM securities for either the three months ended March 31, 2025 or 2024. As of both March 31, 2025 and December 31, 2024, the accrued interest receivable on HTM securities totaled $0.9 million and is included within other assets on the Consolidated Balance Sheets. The Company didnot record any write-offs of accrued interest receivable on HTM securities during either the three months ended March 31, 2025 or 2024. No HTM securities held by the Company were delinquent on contractual payments as of either March 31, 2025 or December 31, 2024, nor were any HTM securities placed on non-accrual status during the three and twelve month periods then ended.

Available for Sale and Held to Maturity Securities Contractual Maturity

The amortized cost and estimated fair value of AFS and HTM securities by contractual maturities as of March 31, 2025 and December 31, 2024 are shown below. Actual maturities may differ from contractual maturities because borrowers may have the right to call or prepay obligations with or without prepayment penalties.

The scheduled contractual maturities of AFS and HTM securities as of the dates indicated were as follows:

Securities Pledged as Collateral

As of March 31, 2025 and December 31, 2024, securities with a carrying value of $576.6 million and $687.9 million, respectively, were pledged to secure public deposits and for other purposes required by law. As of March 31, 2025 and December 31, 2024, deposits with associated pledged collateral included cash accounts from the Company’s wealth management division (“Cambridge Trust Wealth Management”) and municipal deposit accounts. As of March 31, 2025 and December 31, 2024, securities with a carrying value of $0.3 billion and $1.0 billion, respectively, were pledged as collateral to the FHLBB.

As of March 31, 2025 and December 31, 2024, the Company pledged securities with a carrying value of $440.5 million and $794.8 million, respectively, to the Federal Reserve Discount Window (the “Discount Window”).

4. Loans and Allowance for Credit Losses

Loans

The following table provides a summary of the Company’s loan portfolio as of the dates indicated:

(1)The balance of accrued interest receivable excluded from amortized cost and the calculation of the allowance for loan losses amounted to $64.1 million and $66.7 million as of March 31, 2025 and December 31, 2024, respectively, and is included within other assets on the Consolidated Balance Sheets.

There are no other loan categories that exceed 10% of total loans not already reflected in the preceding table.

The Company’s lending activities are conducted principally in the New England area with the exception of its Shared National Credit Program (“SNC Program”) portfolio and certain purchased loans. The Company participates in the SNC Program in an effort to improve its industry and geographical diversification. The SNC Program portfolio is included in the Company’s commercial and industrial, commercial real estate, and commercial construction portfolios. The SNC Program portfolio is defined as loan syndications with exposure over $100 million and with three or more lenders participating.

Most loans originated by the Company are either collateralized by real estate or other assets or guaranteed by federal and local governmental authorities. The ability and willingness of the single-family residential and consumer borrowers to honor their repayment commitments is generally dependent on the level of overall economic activity within the borrowers’ geographic areas and real estate values. The ability and willingness of commercial real estate, commercial and industrial, and construction loan borrowers to honor their repayment commitments is generally dependent on the health of the real estate economy in the borrowers’ geographic areas and the general economy.

Loans Pledged as Collateral

The carrying value of loans pledged to secure advances from the Federal Home Loan Bank (“FHLB”) of Boston (“FHLBB”) were $2.2 billion and $2.3 billion at March 31, 2025 and December 31, 2024, respectively. The balance of funds borrowed from the FHLBB were $20.1 million and $17.6 million at March 31, 2025 and December 31, 2024, respectively.

The carrying value of loans pledged to secure advances from the Federal Reserve Bank (“FRB”) were $3.6 billion and $3.1 billion at March 31, 2025 and December 31, 2024, respectively. There wereno funds borrowed from the FRB outstanding at March 31, 2025 or December 31, 2024.

Serviced Loans

At March 31, 2025 and December 31, 2024, mortgage loans partially or wholly-owned by others and serviced by the Company amounted to approximately $222.3 million and $228.4 million, respectively.

Allowance for Loan Losses

The allowance for loan losses is established to provide for management’s estimate of expected lifetime credit losses on loans measured at amortized cost at the balance sheet date through a provision for loan losses charged to net income. Charge-offs, net of recoveries, are charged directly to the allowance for loan losses. Commercial and residential loans are charged-off in the period in which they are deemed uncollectible. Delinquent loans in these product types are subject to ongoing review and analysis to determine if a charge-off in the current period is appropriate. For consumer loans, policies and procedures exist that require charge-off consideration upon a certain triggering event depending on the product type.

The following tables summarize the changes in the allowance for loan losses by loan category for the periods indicated:

The allowance for loan losses decreased $4.6 million, or 2.0%, to $224.3 million as of March 31, 2025 from $229.0 million as of December 31, 2024. The decrease in the allowance for loan losses for the three months ended March 31, 2025 was primarily due to a reduction in specific reserves that was driven by the transfer of a non-performing commercial real estate loan to held-for-sale classification and the sale of a non-performing commercial and industrial loan, both of which had previously been reserved for on a specific reserve basis.

Reserve for Unfunded Commitments

Management evaluates the need for a reserve on unfunded lending commitments in a manner consistent with loans held for investment. As of March 31, 2025 and December 31, 2024, the Company’s reserve for unfunded lending commitments was $13.0 million and $13.1 million, respectively, which is recorded within other liabilities in the Company's Consolidated Balance Sheets.

Portfolio Segmentation

Management uses a methodology to systematically estimate the amount of expected losses in each segment of loans in the Company’s portfolio. Commercial and industrial business banking, investment commercial real estate, and commercial and industrial loans are evaluated based upon loan-level risk characteristics, historical losses and other factors which form the basis for estimating expected losses. Other portfolios, including owner occupied commercial real estate (which includes business banking owner occupied commercial real estate), commercial construction, residential mortgages, home equity and consumer loans, are analyzed as groups taking into account delinquency ratios, and the Company’s and peer banks’ historical loss experience. For the purposes of estimating the allowance for loan losses, management segregates the loan portfolio into loan categories that share similar risk characteristics such as the purpose of the loan, repayment source, and collateral. These characteristics are considered when determining the appropriate level of the allowance for each category. Some examples of these risk characteristics unique to each loan category include:

Commercial Lending

Commercial and industrial: The primary risk associated with commercial and industrial loans is the ability of borrowers to achieve business results consistent with those projected at origination. Collateral frequently consists of a first lien position on business assets including, but not limited to, accounts receivable, inventory, aircraft and equipment. The primary repayment source is operating cash flow and, secondarily, the liquidation of assets. Under its lending guidelines, the Company generally requires a corporate or personal guarantee from any entity or individual that holds a material ownership in the borrowing entity when the loan-to-value of a commercial and industrial loan is in excess of a specified threshold.

Commercial real estate: Collateral values are established by independent third-party appraisals and evaluations. Primary repayment sources include operating income generated by the real estate, permanent debt refinancing, sale of the real estate and, secondarily, liquidation of the collateral. Under its lending guidelines, the Company generally requires a corporate or personal guarantee from individuals that hold material ownership in the borrowing entity when the loan-to-value of a commercial real estate loan is in excess of a specified threshold.

Commercial construction: These loans are generally considered to present a higher degree of risk than other real estate loans and may be affected by a variety of factors, such as adverse changes in interest rates and the borrower’s ability to control costs and adhere to time schedules. Construction loans are underwritten utilizing feasibility studies, independent appraisal reviews, sensitivity analysis of absorption and lease rates and financial analysis of the developers and property owners. Construction loans are generally based upon estimates of costs and value associated with the completed project. Construction loan repayment is substantially dependent on the ability of the borrower to complete the project and obtain permanent financing.

Business banking: These loans are typically secured by all business assets or commercial real estate. Business banking originations include traditionally underwritten loans as well as partially automated scored loans. Business banking scored loans are determined by utilizing the Company’s proprietary decision matrix that has a number of quantitative factors including, but not limited to, a guarantor’s credit score, industry risk, and time in business. The Company also engages in Small Business Association (“SBA”) lending. The SBA guarantees reduce the Company’s loss due to default and are considered a credit enhancement to the loan structure.

Residential Lending

These loans are made to borrowers who demonstrate the ability to repay principal and interest on a monthly basis. Underwriting considerations include, among others, income sources and their reliability, willingness to repay as evidenced by credit repayment history, financial resources (including cash reserves) and the value of the collateral. The Company maintains policy standards for minimum credit score and cash reserves and maximum loan-to-value consistent with a “prime” portfolio. Collateral consists of mortgage liens on 1-4 family residential dwellings. The policy standards applied to loans originated by the Company are the same as those applied to purchased loans. The Company does not originate or purchase sub-prime or other high-risk loans. Residential loans are originated either for sale to investors or retained in the Company’s loan portfolio. Decisions about whether to sell or retain residential loans are made based on the interest rate characteristics, pricing for loans in the secondary mortgage market, competitive factors and the Company’s liquidity and capital needs.

Consumer Lending

Consumer home equity: Home equity lines of credit are granted for ten years with monthly interest-only repayment requirements. At the end of the ten-year draw period, home equity lines of credit are amortized over the remaining maturity period and monthly payments of principal and interest are required. Home equity loans are term loans that require the monthly payment of principal and interest such that the loan will be fully amortized at maturity. Underwriting considerations are materially consistent with those utilized in residential real estate. Collateral consists of a senior or subordinate lien on owner-occupied residential property.

Other consumer: The Company’s policy and underwriting in this category, which is comprised primarily of home improvement, automobile and aircraft loans, include the following factors, among others: income sources and reliability, credit histories, term of repayment, and collateral value, as applicable. These are typically granted on an unsecured basis, with the exception of aircraft and automobile loans.

Credit Quality

Commercial Lending Credit Quality

The credit quality of the Company’s commercial loan portfolio is actively monitored and supported by a comprehensive credit approval process and all large dollar transactions are sent for approval to a committee of seasoned business line and credit professionals. The Company maintains an independent credit risk review function that reports directly to the Risk Management Committee of the Board of Directors. Credits that demonstrate significant deterioration in credit quality are transferred to a specialized group of experienced officers for individual attention.

The Company monitors credit quality indicators and utilizes portfolio scorecards to assess the risk of its commercial portfolio. Specifically, the Company utilizes a 15-point credit risk-rating system to manage risk and identify potential problem loans. Under this point system, risk-rating assignments are based upon a number of quantitative and qualitative factors that are under continual review. Factors include cash flow, collateral coverage, liquidity, leverage, position within the industry, internal controls and management, financial reporting, and other considerations. Commercial loan risk ratings are (re)evaluated for each loan at least once-per-year. The risk-rating categories under the credit risk-rating system are defined as follows:

0 Risk Rating - Unrated

Certain segments of the portfolios are not rated. These segments include aircraft loans, business banking scored loan products, and other commercial loans managed by exception. Loans within this unrated loan segment are monitored by delinquency status; and for lines of credit greater than $100,000 in exposure, an annual review is conducted which includes the review of the business score and loan and deposit account performance. The Company supplements performance data with current business credit scores for the business banking portfolio on a quarterly basis. Unrated commercial and business banking loans are generally restricted to commercial exposure of less than $1.5 million. Loans included in this category generally are not required to provide regular financial reporting or regular covenant monitoring.

For purposes of estimating the allowance for loan losses, unrated loans are considered in the same manner as “Pass” rated loans. Unrated loans are included with “Pass” rated loans for disclosure purposes.

1-10 Risk Rating – Pass

Loans with a risk rating of 1-10 are classified as “Pass” and are comprised of loans that range from “substantially risk free” which indicates borrowers of unquestioned credit standing, well-established national companies with a very strong financial condition, and loans fully secured by policy conforming cash levels, through “low pass” which indicates acceptable rated loans that may be experiencing weak cash flow, impending lease rollover or minor liquidity concerns.

11 Risk Rating – Special Mention (Potential Weakness)

Loans to borrowers in this category exhibit potential weaknesses or downward trends deserving management’s close attention. While potentially weak, no loss of principal or interest is envisioned. Included in this category are borrowers who are performing as agreed, are weak when compared to industry standards, may be experiencing an interim loss and may be in declining industries. An element of asset quality, financial flexibility or management is below average. The Company does not consider borrowers within this category as new business prospects. Borrowers rated special mention may find it difficult to obtain alternative financing from traditional bank sources.

12 Risk Rating – Substandard (Well-Defined Weakness)

Loans with a risk-rating of 12 exhibit well-defined weaknesses that, if not corrected, may jeopardize the orderly liquidation of the debt. A loan is classified as substandard if it is inadequately protected by the repayment capacity of the obligor or by the collateral pledged. Specifically, repayment under market rates and terms, or by the requirements under the existing loan documents, is in jeopardy, but no loss of principal or interest is envisioned. There is a possibility that a partial loss of principal and/or interest will occur in the future if the deficiencies are not corrected. Loss potential, while existing in the aggregate portfolio of substandard assets, does not have to exist in individual assets classified as substandard. Non-accrual is possible, but not mandatory, in this class.

13 Risk Rating – Doubtful (Loss Probable)

Loans classified as doubtful have comparable weaknesses as found in the loans classified as substandard, with the added provision that such weaknesses make collection of the debt in full (based on currently existing facts, conditions and values) highly questionable and improbable. Serious problems exist such that a partial loss of principal is likely. The probability of loss exists, but because of reasonably specific pending factors that may work to strengthen the credit, estimated losses are deferred until a more exact status can be determined. Specific reserves will be the amount identified after specific review. Non-accrual is mandatory in this class.

14 Risk Rating – Loss

Loans to borrowers in this category are deemed incapable of repayment. Loans to such borrowers are considered uncollectible and of such little value that continuance as active assets of the Company is not warranted. This classification does not mean that the loans have no recovery or salvage value, but rather, it is not practical or desirable to defer writing off these assets even though partial recovery may occur in the future. Loans in this category have a recorded investment of $0 at the time of the downgrade.

Residential and Consumer Lending Credit Quality

For the Company’s residential and consumer portfolios, the quality of the loan is best indicated by the repayment performance of an individual borrower. Updated appraisals, broker opinions of value and other collateral valuation methods are employed in the residential and consumer portfolios, typically for credits that are deteriorating. Delinquency status is determined using payment performance, while accrual status may be determined using a combination of payment performance, expected borrower viability and collateral value. Delinquent consumer loans are handled by a team of seasoned collection specialists.

The following table details the amortized cost balances of the Company’s loan portfolios, presented by credit quality indicator and origination year as of March 31, 2025, and gross charge-offs for the three month period then ended:

(1)The amounts presented represent the amortized cost as of March 31, 2025 of revolving loans that were converted to term loans during the three months ended March 31, 2025.

The following table details the amortized cost balances of the Company’s loan portfolios, presented by credit quality indicator and origination year as of December 31, 2024:

(1)The amounts presented represent the amortized cost as of December 31, 2024 of revolving loans that were converted to term loans during the year ended December 31, 2024.

Asset Quality

The Company manages its loan portfolio with careful monitoring. As a general rule, loans more than 90 days past due with respect to principal and interest are classified as non-accrual loans. Exceptions may be made if management believes that collateral held by the Company is clearly sufficient and in full satisfaction of both principal and interest. The Company may also use discretion regarding other loans over 90 days delinquent if the loan is well secured and in the process of collection. Non-accrual loans and loans that are more than 90 days past due but still accruing interest are considered non-performing loans.

Non-accrual loans may be returned to an accrual status when principal and interest payments are no longer delinquent, and the risk characteristics of the loan have improved to the extent that there no longer exists a concern as to the collectability of principal and interest. Loans are considered past due based upon the number of days delinquent according to their contractual terms.

A loan is expected to remain on non-accrual status until it becomes current with respect to principal and interest, the loan is liquidated, or the loan is determined to be uncollectible and is charged-off against the allowance for loan losses.

The following tables show the age analysis of past due loans as of the dates indicated:

The following table presents information regarding non-accrual loans as of the dates indicated:

(1)The loans on non-accrual status and without an ACL as of both March 31, 2025 and December 31, 2024, were primarily comprised of collateral dependent loans for which the fair value of the underlying loan collateral exceeded the loan carrying value.

The amount of interest income recognized on non-accrual loans during the three months ended March 31, 2025 and 2024 was not significant. As of both March 31, 2025 and December 31, 2024, there were no loans greater than 90 days past due and still accruing.

It is the Company’s policy to reverse any accrued interest when a loan is put on non-accrual status and, generally, to record any payments received from a borrower related to a loan on non-accrual status as a reduction of the amortized cost basis of the loan. Accrued interest reversed against interest income for the three months ended March 31, 2025 and 2024 was not significant.

For collateral values for residential mortgage and home equity loans, the Company relies primarily upon third-party valuation information from certified appraisers and values are generally based upon recent appraisals of the underlying collateral, brokers’ opinions based upon recent sales of comparable properties, or estimated auction or liquidation values less estimated costs to sell. As of March 31, 2025 and December 31, 2024, the Company had collateral-dependent residential mortgage and home equity loans totaling $1.6 million and $1.1 million, respectively.

For collateral-dependent commercial loans, the amount of the allowance for loan losses is individually assessed based upon the fair value of the collateral. Various types of collateral are used, including real estate, inventory, equipment, accounts receivable, securities and cash, among others. For commercial real estate loans, the Company relies primarily upon third-party valuation information from certified appraisers and values are generally based upon recent appraisals of the underlying collateral, brokers’ opinions based upon recent sales of comparable properties, estimated equipment auction or liquidation values, income capitalization, or a combination of income capitalization and comparable sales. As of March 31, 2025 and December 31, 2024, the Company had collateral-dependent commercial loans totaling $63.0 million and $107.7 million, respectively.

Appraisals for all loan types are obtained at the time of loan origination as part of the loan approval process and are updated at the time of a loan modification and/or refinance and as considered necessary by management for impairment review purposes. In addition, appraisals are updated as required by regulatory pronouncements.

As of both March 31, 2025 and December 31, 2024, the Company had no residential real estate held in other real estate owned (“OREO”). As of March 31, 2025, there were seven residential real estate loans, which had an aggregate balance of $0.8 million, collateralized by residential real estate property for which formal foreclosure proceedings were in-process. As of December 31, 2024, there were four residential real estate loans, which had an aggregate balance of $0.4 million, collateralized by residential real estate property for which formal foreclosure proceedings were in-process. As of March 31, 2025, there were five consumer home equity loans, which had an aggregate balance of $0.6 million, collateralized by residential real estate property for which formal foreclosure proceedings were in-process. As of December 31, 2024, there weresix consumer home equity loans, which had an aggregate balance of $0.5 million, collateralized by residential real estate property for which formal foreclosure proceedings were in-process.

Loan Modifications to Borrowers Experiencing Financial Difficulty

The following table shows the amortized cost balance as of March 31, 2025 and 2024 of loans modified during the three month periods then ended to borrowers experiencing financial difficulty by the type of concession granted:

The following tables describe the financial effect of the modifications made during the periods indicated to borrowers experiencing financial difficulty. Loans that were modified in more than one manner are included in each modification type corresponding to the types of modifications performed.

(1)Loans that were modified in more than one manner are included in each modification type corresponding to the type of modifications performed.

(1)Loans that were modified in more than one manner are included in each modification type corresponding to the type of modifications performed.

As of March 31, 2025, no loans to borrowers experiencing financial difficulty modified during the prior twelve months had a payment default during the three months ended March 31, 2025. As of March 31, 2024, no loans to borrowers experiencing financial difficulty modified during the prior twelve months had a payment default during the three months ended March 31, 2024.

Management closely monitors the performance of loans that are modified to borrowers experiencing financial difficulty to understand the effectiveness of its modification efforts. The following table shows the age analysis of past due loans to borrowers experiencing financial difficulty that were modified during the prior twelve months as of March 31, 2025:

The following table shows the age analysis of past due loans to borrowers experiencing financial difficulty that were modified during the prior twelve months as of March 31, 2024:

As of March 31, 2025, there wereno additional commitment to lend to borrowers experiencing financial difficulty and which was modified during the three months ended March 31, 2025 in the form of principal forgiveness, an interest rate reduction, an other-than-insignificant delay in repayment, or a term extension. As of December 31, 2024, there wasone additional commitment to lend amounting to $0.3 million to borrowers experiencing financial difficulty and which were modified during year ended December 31, 2024 in the form of principal forgiveness, an interest rate reduction, an other-than-insignificant delay in repayment, or a term extension.

Loan Participations

The Company occasionally purchases commercial loan participations or participates in syndications through the SNC Program. These participations meet the same underwriting, credit and portfolio management standards as the Company’s other loans and are applied against the same criteria to determine the allowance for loan losses as other loans.

The following table summarizes the Company’s loan participations:

5. Leases

The Company leases certain office space and equipment under various non-cancelable operating leases. These leases have original terms ranging from 2 years to 24 years. Operating lease liabilities and right-of-use (“ROU”) assets are recognized at the lease commencement date based upon the present value of the future minimum lease payments over the lease term. Operating lease liabilities are recorded within other liabilities and ROU assets are recorded within other assets in the Company’s Consolidated Balance Sheets.

As of the dates indicated, the Company had the following related to operating leases:

The increase in the Company’s right-of-use assets and lease liabilities at March 31, 2025 from December 31, 2024, is primarily due to the addition of a new lease located in Wakefield, MA which amounted to $11.4 million and will house Company offices once certain leasehold improvements are completed.

Finance leases are not material. Finance lease liabilities are recorded within other liabilities and finance ROU assets are recorded within other assets in the Company’s Consolidated Balance Sheets.

The following table is a summary of the Company’s components of net lease cost for the periods indicated:

During the three months ended March 31, 2025, the Company made $4.0 million and $3.5 million, respectively, in cash payments for operating and finance lease payments.

Supplemental balance sheet information related to operating leases are as follows:

The following table sets forth the undiscounted cash flows of base rent related to operating leases outstanding as of March 31, 2025 with payments scheduled over the next five years and thereafter, including a reconciliation to the operating lease liability recognized in other liabilities in the Company’s Consolidated Balance Sheets:

6.(Loss) Earnings Per Share (“EPS”)

Basic EPS represents (loss)/income allocable to common shareholders divided by the weighted-average number of common shares outstanding during the period. Diluted EPS reflects the potential dilution that could occur if securities or other contracts to issue common shares (such as stock options) were exercised or converted into additional common shares that would then share in the earnings of the Company. Diluted EPS is computed by dividing net (loss)/income allocable to common shareholders by the weighted-average number of common shares outstanding for the period, plus the effect of potential dilutive common share equivalents computed using the treasury stock method. Shares held by the Employee Stock Ownership Plan (“ESOP”) that have not been allocated to employees in accordance with the terms of the ESOP, referred to as “unallocated ESOP shares,” are not deemed outstanding for earnings per share calculations. The following are the components and results of the Company’s earnings per common share calculations for the periods presented:

7. Low Income Housing Tax Credits and Other Tax Credit Investments

The Community Reinvestment Act (“CRA”) encourages banks to meet the credit needs of their communities for housing and other purposes, particularly in neighborhoods with low or moderate income. The Company has primarily invested in separate Low Income Housing Tax Credits (“LIHTC”) projects, also referred to as qualified affordable housing projects, which provide the Company with tax credits and operating loss tax benefits over a period of 15 years. The return on these investments is generally generated through tax credits and tax losses. In addition to LIHTC projects, the Company invests in new market tax credit projects that qualify for CRA credits and eligible projects that qualify for renewable energy and historic tax credits.

As of March 31, 2025 and December 31, 2024, the Company had $216.4 million and $222.7 million, respectively, in tax credit investments that were included in other assets in the Company’s Consolidated Balance Sheets.

When permissible, the Company accounts for its investments in LIHTC projects and other qualifying investments using the proportional amortization method, under which it amortizes the initial cost of the investment in proportion to the amount of the tax credits and other tax benefits received and recognizes that amortization as a component of income tax expense. The net investment in the housing projects is included in other assets in the Company’s Consolidated Balance Sheets. The Company will continue to use the proportional amortization method on any new qualifying investments.

The following table presents the Company’s investments in LIHTC projects accounted for using the proportional amortization method for the periods indicated:

The following table presents additional information related to the Company’s investments in LIHTC projects for the periods indicated:

The Company accounts for certain other investments in renewable energy projects using the equity method of accounting. These investments in renewable energy projects are included in other assets in the Company’s Consolidated Balance Sheets and totaled $1.8 million and $1.9 million as of March 31, 2025 and December 31, 2024, respectively. There wereno outstanding commitments related to these investments as of either March 31, 2025 or December 31, 2024.

8. Income Taxes

The following table sets forth information regarding the Company’s tax provision and applicable tax rates for the periods indicated:

The Company recorded net income tax expense of $33.7 million and $10.3 million for the three months ended March 31, 2025 and 2024, respectively.

The Company recorded net income tax expense during the three months ended March 31, 2025 despite a net pre-tax loss recognized during the period. The loss on sale of securities recognized during the three months ended March 31, 2025 is not considered to be a discrete item for tax purposes and, therefore, the associated tax benefit of $67.9 million is realizable ratably over the full year. The increase in income tax expense for the three months ended March 31, 2025 compared to the three months ended March 31, 2024 was primarily due to the previously discussed partial recognition of the tax benefit associated with the sale of securities during the three months ended March 31, 2025.

9. Employee Benefits

Pension Plans

The Company provides pension benefits for its employees through membership in the Savings Banks Employees’ Retirement Association. The plan through which benefits are provided is a noncontributory, qualified defined benefit plan and is referred to as the Defined Benefit Plan. The Company’s annual contribution to the Defined Benefit Plan is based upon standards established by the Pension Protection Act. The contribution is based on an actuarial method intended to provide not only for benefits attributable to service to date, but also for those expected to be earned in the future. The Defined Benefit Plan has a plan year end of October 31.

The Company has an unfunded Defined Benefit Supplemental Executive Retirement Plan (“DB SERP”) that provides certain Company officers upon their retirement with defined pension benefits in excess of qualified plan limits imposed by U.S. federal tax law. The DB SERP has a plan year end of December 31.

In addition, the Company has an unfunded Benefit Equalization Plan (“BEP”) to provide retirement benefits to certain employees whose retirement benefits under the qualified pension plan are limited per the Internal Revenue Code. The BEP has a plan year end of October 31.

The Company also has an unfunded Outside Directors’ Retainer Continuance Plan (“ODRCP”) that provides pension benefits to outside directors who retire from service. The ODRCP has a plan year end of December 31. Effective December 31, 2020, the Company closed the ODRCP to new participants and froze benefit accruals for active participants.

Components of Net Periodic Benefit Cost

The components of net pension expense for the plans for the periods indicated are as follows:

Service costs for the Defined Benefit Plan, the BEP, and the DB SERP are recognized within salaries and employee benefits in the Consolidated Statements of Income. The remaining components of net periodic benefit cost are recognized in other noninterest expense in the Consolidated Statements of Income.

In accordance with the Pension Protection Act, the Company was not required to make any contributions to the Defined Benefit Plan for the plan years beginning November 1, 2024 and 2023. Accordingly, during the three months ended March 31, 2025 and 2024, there wereno contributions made to the Defined Benefit Plan.

Share-Based Compensation Plan

On November 29, 2021, the shareholders of the Company approved the Eastern Bankshares, Inc. 2021 Equity Incentive Plan (the “2021 Plan”). The 2021 Plan provides for the issuance of up to 26,146,141 shares of common stock pursuant to grants of restricted stock, restricted stock units (“RSUs”), non-qualified stock options and incentive stock options, any or all of which can be granted with performance-based vesting conditions. Under the 2021 Plan,7,470,326 shares may be issued as restricted stock or RSUs, including those issued as performance shares and performance share units (“PSUs”), and 18,675,815 shares may be issued upon the exercise of stock options. These shares may be awarded from the Company’s authorized but unissued shares. However, the 2021 Plan permits the grant of additional awards of restricted stock or RSUs above the aforementioned limit, provided that, for each additional share of restricted stock or RSU awarded in excess of such limit, the pool of shares available to be issued upon the exercise of stock options will be reduced bythree shares. Pursuant to the terms of the 2021 Plan, each of the Company’s non-employee directors were automatically granted awards of restricted stock on November 30, 2021. Such restricted stock awards (“RSAs”) vest pro-rata on an annual basis over afive-year period. The maximum term for stock options isten years.

In March 2025, the Company granted to all of the Company’s executive officers and certain other employees a total of 630,493 RSUs, which vest pro-rata on an annual basis over a period ofthree years from the date of the grant, and a total of 339,503 PSUs for which vesting is contingent upon the Compensation and Human Capital Management Committee of the

Board of Director’s certification, after the conclusion of a period of approximately 2.8 years from the date of the grant, that the Company has attained a threshold level of certain performance criteria over such period.

In March 2024, the Company granted to all of the Company’s executive officers and certain other employees a total of 416,276 RSUs, which vest pro-rata on an annual basis over a period ofthree years from the date of the grant, and a total of 234,091 PSUs for which vesting is contingent upon the Compensation and Human Capital Management Committee of the Board of Director’s certification, after the conclusion of a period of approximately 2.8 years from the date of the grant, that the Company has attained a threshold level of certain performance criteria over such period.

As of March 31, 2025 and December 31, 2024, there were 3,177,556 shares and 3,844,157 shares that remained available for issuance as restricted stock or RSU awards (including those that may be issued as performance shares and PSUs), respectively, and 18,675,815 shares that remained available for issuance upon the exercise of stock options at both dates. As of both March 31, 2025 and December 31, 2024, no stock options had been awarded under the 2021 Plan.

The following table summarizes the Company’s restricted stock award activity for the periods indicated:

During the three months ended March 31, 2025,22,103 RSA awards vested. Such awards had a grant date fair value of $0.3 million. No awards vested during the three months ended March 31, 2024.

The following table summarizes the Company’s restricted stock unit activity for the periods indicated:

During the three months ended March 31, 2025 and 2024,458,079 and 303,015 RSU awards vested, respectively. Such awards had a grant date fair value of $7.9 million and $5.9 million, respectively.

The following table summarizes the Company’s performance stock unit activity for the periods indicated:

During the three months ended March 31, 2025,408,629 PSU awards vested. Such awards had a grant date value of $8.6 million. No PSU awards vested during the three months ended March 31, 2024.

Included in vested RSU and PSU shares shown in the tables above, are shares withheld for employee payroll taxes. The aggregate number of RSU and PSU shares withheld for payroll taxes during the three months ended March 31, 2025 and 2024 was 330,038 and 98,351, respectively.

The following table shows share-based compensation expense under the 2021 Plan and the related tax benefit for the periods indicated:

(1)Estimated based upon the Company’s statutory rate for each respective period.

As of March 31, 2025 and December 31, 2024, there was $31.3 million and $21.4 million, respectively, of total unrecognized compensation expense related to unvested restricted stock awards, restricted stock units and performance stock units granted and issued under the 2021 Plan, as applicable. As of March 31, 2025, this cost is expected to be recognized over a weighted average remaining period of approximately 2.2 years. As of December 31, 2024, this cost was expected to be recognized over a weighted average remaining period of approximately 1.4 years.

10. Commitments and Contingencies

Financial Instruments with Off-Balance Sheet Risk

In order to meet the financing needs of its customers and to reduce its own exposure to fluctuations in interest rates, the Company is party to financial instruments with off-balance sheet risk in the normal course of business. These financial instruments include commitments to extend credit, standby letters of credit, and forward commitments to sell loans, all of which involve, to varying degrees, elements of credit and interest rate risk in excess of the amount recognized in the Consolidated Balance Sheets. The contract or notional amounts of those instruments reflect the extent of involvement the Company has in each particular class of financial instruments.

Substantially all of the Company’s commitments to extend credit, which normally have fixed expiration dates or termination clauses, are contingent upon customers maintaining specific credit standards at the time of loan funding. Standby letters of credit are conditional commitments issued by the Company to guarantee the performance of a customer to a third party. In the event the customer does not perform in accordance with the terms of agreement with the third party, the Company would be required to fund the commitment. The maximum potential amount of future payments the Company could be required to make is represented by the contractual amount of the commitment. The credit risk involved in issuing letters of credit is essentially the same as that involved in extending loan facilities to customers. For forward loan sale commitments, the contract or notional amount does not represent exposure to credit loss. The Company generally does not sell loans with recourse.

The following table summarizes the above financial instruments as of the dates indicated:

Other Contingencies

Legal Proceedings

The Company has been named a defendant in various legal proceedings arising in the normal course of business. In the opinion of management, based on the advice of legal counsel, the ultimate resolution of these proceedings is not expected to have a material effect on the Company’s Consolidated Financial Statements.

11. Derivative Financial Instruments

The Company uses derivative financial instruments to manage its interest rate risk resulting from the differences in the amount, timing, and duration of known or expected cash receipts and known or expected cash payments. Additionally, the Company enters into interest rate derivatives and foreign exchange contracts to accommodate the business requirements of its customers (“customer-related positions”) and risk participation agreements entered into as financial guarantees of performance on customer-related interest rate swap derivatives. The Company also enters into residential mortgage loan commitments to fund mortgage loans at specified rates and times in the future and enters into forward sale commitments to sell such residential mortgage loans at specified prices and times in the future, both of which are considered derivative instruments. Derivative instruments are carried at fair value in the Company’s Consolidated Financial Statements. The accounting for changes in the fair value of a derivative instrument is dependent upon whether or not the instrument qualifies as a hedge for accounting purposes, and further, by the type of hedging relationship.

By using derivatives, the Company is exposed to credit risk to the extent that counterparties to the derivative contracts do not perform as required. Should a counterparty fail to perform under the terms of a derivative contract, the Company’s credit exposure on interest rate swaps is limited to the net positive fair value and accrued interest of all swaps with each counterparty plus any initial margin collateral posted. The Company seeks to minimize counterparty credit risk through credit approvals, limits, monitoring procedures, and obtaining collateral, where appropriate. As such, management believes the risk of incurring credit losses on derivative contracts with those counterparties is remote. The Company’s discounting methodology and interest calculation of cash margin uses the Secured Overnight Financing Rate, or SOFR, for U.S. dollar cleared interest rate swaps.

Interest Rate Positions

An interest rate swap is an agreement whereby one party agrees to pay a floating rate of interest on a notional principal amount in exchange for receiving a fixed rate of interest on the same notional amount, for a predetermined period of time, from a second party. The amounts relating to the notional principal amount are not actually exchanged. The Company has entered into interest rate swaps in which it pays floating and receives fixed interest in order to manage its interest rate risk exposure to the variability in interest cash flows on certain floating-rate loans. Such interest rate swaps include those which effectively convert the floating rate one-month SOFR or overnight indexed swap rate, or prime rate interest payments received on the loans to a fixed rate and consequently reduce the Company’s exposure to variability in short-term interest rates. For interest rate swaps that are accounted for as cash flow hedges, changes in fair value are included in other comprehensive income and reclassified into net income in the same period or periods during which the hedged forecasted transaction affects net income. The following tables reflect the Company’s derivative positions for interest rate swaps which qualify as cash flow hedges for accounting purposes as of the dates indicated:

(1)The fair value included a net accrued interest payable balance of $1.5 million as of March 31, 2025. In addition, the fair value includes netting adjustments which represent the amounts recorded to convert derivative assets and liabilities cleared through the Chicago Mercantile Exchange, or CME, from a gross basis to a net basis in accordance with applicable accounting guidance.

(1)The fair value included a net accrued interest payable balance of $1.6 million as of December 31, 2024. In addition, the fair value includes netting adjustments which represent the amounts recorded to convert derivative assets and liabilities cleared through the CME from a gross basis to a net basis in accordance with applicable accounting guidance.

The maximum amount of time over which the Company is currently hedging its exposure to the variability in future cash flows of forecasted transactions related to the receipt of variable interest on existing financial instruments is 2.5 years.

The Company expects approximately $19.2 million will be reclassified into interest income, as a reduction of such income, from other comprehensive income related to the Company’s active cash flow hedges in the next 12 months as of March 31, 2025. The reclassification is due to anticipated net payments on the swaps based upon the forward curve as of March 31, 2025.

Customer-Related Positions

Interest rate swaps offered to commercial customers do not qualify as hedges for accounting purposes. These swaps allow the Company to retain variable rate commercial loans while allowing the commercial customer to synthetically fix the loan rate by entering into a variable-to-fixed rate interest rate swap. The Company believes that its exposure to commercial customer derivatives is limited to non-performance by either the customer or the dealer because these contracts are simultaneously matched at inception with an offsetting transaction.

Risk participation agreements are entered into as financial guarantees of performance on interest rate swap derivatives. The purchased (asset) or sold (liability) guarantee allow the Company to participate-out (fee paid) or participate-in (fee received) the risk associated with certain derivative positions executed with the borrower by the lead bank in a customer-related interest rate swap derivative.

Foreign exchange contracts consist of those offered to commercial customers and those entered into to hedge the Company’s foreign currency risk associated with a foreign-currency loan. Neither qualifies as a hedge for accounting purposes. These commercial customer derivatives are offset with matching derivatives with correspondent-bank counterparties in order to minimize foreign exchange rate risk to the Company. Exposure with respect to these derivatives is largely limited to non-performance by either the customer or the other counterparty. Neither the Company nor the correspondent-bank counterparty are required to post collateral but each has established foreign-currency transaction limits to manage the exposure risk. The Company requires its customers to post collateral to minimize risk exposure.

The following tables present the Company’s customer-related derivative positions as of the dates indicated below for those derivatives not designated as hedging:

The level of interest rate swaps, risk participation agreements and foreign currency exchange contracts at the end of each period noted above was commensurate with the activity throughout those periods.

The table below presents the fair value of the Company’s derivative financial instruments, as well as their classification on the Consolidated Balance Sheets for the periods indicated:

The table below presents the net effect of the Company’s derivative financial instruments on the Consolidated Income Statements as well as the effect of the Company’s derivative financial instruments included in other comprehensive income (“OCI”) as follows:

The Company has agreements with its customer-related interest rate swap derivative counterparties that contain a provision whereby if the Company defaults on any of its indebtedness, including default where repayment of the indebtedness has not been accelerated by the lender, then the Company could also be declared in default on its derivative obligations.

The Company also has agreements with certain of its customer-related interest rate swap derivative correspondent-bank counterparties that contain a provision whereby if the Company fails to maintain its status as a well-capitalized institution, then the counterparty could terminate the derivative positions and the Company would be required to settle its obligations under the agreements.

The Company’s exposure related to its customer-related interest rate swap derivatives consists of exposure on cleared derivative transactions and exposure on non-cleared derivative transactions.

Cleared derivative transactions are with the Chicago Mercantile Exchange, or CME, and exposure is settled to market daily, with additional credit exposure related to initial-margin collateral pledged to CME at trade execution. At both March 31, 2025 and December 31, 2024, the Company had exposure to CME for settled variation margin in excess of the customer-related and non-customer-related interest rate swap termination values of approximately $0.1 million. In addition, at March 31, 2025 and December 31, 2024, the Company had posted initial-margin collateral in the form of U.S. Treasury notes amounting to $90.1 million and $88.0 million, respectively, to CME for these derivatives. The U.S. Treasury notes were considered restricted assets and were included in available for sale securities within the Company’s Consolidated Balance Sheets.

At both March 31, 2025 and December 31, 2024, there wereno customer-related interest rate swap derivatives with credit-risk contingent features in a net liability position. The Company has minimum collateral posting thresholds with its customer-related interest rate swap derivative correspondent-bank counterparties to the extent that the Company has a liability position with the correspondent-bank counterparties. The Company wasnot required to post cash collateral for interest rate swaps with correspondent-bank counterparties as of either March 31, 2025 or December 31, 2024. If the Company had breached any of these provisions at March 31, 2025 or December 31, 2024, it would have been required to settle its obligations under the agreements at the termination value. In addition, the Company had cross-default provisions with its commercial customer loan agreements which provide cross-collateralization with the customer loan collateral.

Mortgage Banking Derivatives

The Company enters into residential mortgage loan commitments in connection with its consumer mortgage banking activities to fund mortgage loans at specified rates and times in the future. In addition, the Company enters into forward sale commitments to sell such residential mortgage loans at specified prices and times in the future. These commitments are short-term in nature and generally expire in 30 to 60 days. The residential mortgage loan commitments that relate to the origination of mortgage loans that will be held for sale and the related forward sale commitments are considered derivative instruments under ASC Topic 815, “Derivatives and Hedging” and are reported at fair value. Changes in fair value are reported in earnings and included in other non-interest income on the Consolidated Statements of Income. As of March 31, 2025 and December 31, 2024, the Company had an outstanding notional balance of residential mortgage loan origination commitments of $9.9 million and $15.7 million, respectively, and forward sale commitments of $7.1 million and $6.4 million, respectively. During both the three months ended March 31, 2025 and 2024, net gains/losses recorded by the Company related to the change in fair value of commitments to originate and sell mortgage loans were not significant. In addition, the aggregate fair value of the Company’s mortgage banking derivative asset and liability as of March 31, 2025 and December 31, 2024 was not significant. Mortgage banking derivative assets and liabilities are included in other assets and other liabilities, respectively, on the Consolidated Balance Sheets. Residential mortgages sold are generally sold with servicing rights released. Mortgage banking derivatives do not qualify as hedges for accounting purposes.

12. Balance Sheet Offsetting

Certain financial instruments, including derivatives, may be eligible for offset in the Consolidated Balance Sheets and/or subject to master netting arrangements or similar agreements. The Company’s derivative transactions with upstream financial institution counterparties are generally executed under International Swaps and Derivative Association master agreements which include “right of set-off” provisions. In such cases there is generally a legally enforceable right to offset recognized amounts. However, the Company does not offset fair value amounts recognized for derivative instruments. The Company nets the amount recognized for the right to reclaim cash collateral against the obligation to return cash collateral arising from derivative instruments executed with the same counterparty under a master netting arrangement. Collateral legally required to be maintained at dealer banks by the Company is monitored and adjusted as necessary. As of March 31, 2025 and December 31, 2024, it was determined that no additional collateral would have to be posted to immediately settle these instruments.

The following tables present the Company’s asset and liability positions that were eligible for offset and the potential effect of netting arrangements on its Consolidated Balance Sheet, as of the dates indicated:

13. Fair Value of Assets and Liabilities

ASC 820 “Fair Value Measurements and Disclosures” (“ASC 820”) 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 on the measurement date. 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. An orderly transaction is a transaction that assumes exposure to the market for a period prior to the measurement date. Market participants are buyers and sellers in the principal market that are independent, knowledgeable, able and willing to transact. ASC 820 also establishes a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurements), and the lowest priority to unobservable inputs (Level 3 measurements). The three levels of the fair value hierarchy are described below:

Level 1 – Inputs are quoted prices (unadjusted) in active markets for identical assets or liabilities that the reporting entity has the ability to access at the measurement date.

Level 2 – Valuations based on quoted prices in markets that are not active or for which all significant inputs are observable, either directly or indirectly.

Level 3 – Prices or valuations that require unobservable inputs that reflect the Company’s own assumptions that are significant to the fair value measurement.

To the extent that valuation is based on models or inputs that are less observable or unobservable in the market, the determination of fair value requires more judgment. Accordingly, the degree of judgment exercised by the Company in determining fair value is greatest for instruments categorized in Level 3. A financial instrument’s level within the fair value hierarchy is based on the lowest level of any input that is significant to the fair value measurement.

The Company uses fair value measurements to record adjustments to certain assets and liabilities and to determine fair value disclosures. Fair value is best determined based upon quoted market prices. However, in many instances, there are no quoted market prices for the Company’s various financial instruments. In cases where quoted market prices are not available, fair values are based on estimates using present value or other valuation techniques. Those techniques are significantly affected by the assumptions used, including the discount rate and estimates of future cash flows. Accordingly, the fair value estimates may not be realized in an immediate settlement of the instrument.

Fair value is a market-based measure considered from the perspective of a market participant rather than an entity-specific measure. Therefore, even when market assumptions are not readily available, the Company’s own assumptions are set to reflect those that the Company believes market participants would use in pricing the asset or liability at the measurement date. The Company uses prices and inputs that are current as of the measurement date, including during periods of market dislocation. In periods of market dislocation, the observability of prices and inputs may be reduced for many instruments. This condition could cause an instrument to be reclassified from Level 1 to Level 2 or from Level 2 to Level 3.

Fair value estimates are made at a specific point in time, based on relevant market information and information about the financial instrument. These estimates do not reflect any premium or discount that could result from offering for sale at one time the Company’s entire holdings of a particular financial instrument. Because no active market exists for a portion of the Company’s financial instruments, fair value estimates are based on judgments regarding future expected loss experience, current economic conditions, risk characteristics of various financial instruments, and other factors. These estimates are subjective in nature and involve uncertainties and matters of significant judgment, and therefore cannot be determined with precision. Changes in assumptions could significantly affect these estimates.

The following methods and assumptions were used by the Company in estimating fair value disclosures:

Cash and Cash Equivalents

For these financial instruments, which have original maturities of 90 days or less, their carrying amounts reported in the Consolidated Balance Sheets approximate fair value.

Securities

Securities consisted of U.S. Treasury securities, U.S. government-sponsored residential and commercial mortgage-backed securities, state and municipal bonds, and corporate notes as of March 31, 2025. Securities consisted of U.S. Treasury securities, U.S. Agency bonds, U.S. government-sponsored residential and commercial mortgage-backed securities, and state and municipal bonds as of December 31, 2024. AFS securities are recorded at fair value.

The Company’s U.S. Treasury securities are traded on active markets and therefore these securities were classified as Level 1.

The fair value of U.S. Agency bonds, at December 31, 2024, were evaluated using relevant trade data, benchmark quotes and spreads obtained from publicly available trade data, and generated on a price, yield or spread basis as determined by the observed market data. Therefore, these securities were categorized as Level 2 given the use of observable inputs.

The fair value of U.S. government-sponsored residential and commercial mortgage-backed securities were estimated using either a matrix or benchmarks. The inputs used include benchmark yields, reported trades, broker/dealer quotes, and issuer spreads. Therefore, these securities were categorized as Level 2 given the use of observable inputs.

The fair value of state and municipal bonds were estimated using a valuation matrix with inputs including observable bond interest rate tables, recent transactions, and yield relationships. Therefore, these securities were categorized as Level 2 given the use of observable inputs.

The fair value of the corporate note was estimated based upon reported trades and quoted market prices. Therefore, this security was categorized as Level 2 given the use of observable inputs.

Fair value was based on the value of one unit without regard to any premium or discount that may result from concentrations of ownership of a financial instrument, possible tax ramifications, or estimated transaction costs.

Loans Held for Sale

The fair value of loans held for sale, whose carrying amounts approximate fair value, was estimated using the anticipated market price based upon pricing indications provided by investor banks. These assets were classified as Level 2 given the use of observable inputs.

Loans

The fair value of commercial construction, commercial and industrial lines of credit, and certain other consumer loans was estimated by discounting the contractual cash flows using interest rates currently being offered for loans with similar terms to borrowers of similar credit quality.

For commercial, commercial real estate, residential real estate, automobile, and consumer home equity loans, fair value was estimated by discounting contractual cash flows adjusted for prepayment estimates using interest rates currently being offered for loans with similar terms to borrowers of similar credit quality.

Loans are classified as Level 3 since the valuation methodology utilizes significant unobservable inputs. Loans that are deemed to be collateral-dependent, as described in Note 2, “Summary of Significant Accounting Policies” within the Notes to the Consolidated Financial Statements included within the Company’s 2024 Form 10-K, were recorded at the fair value of the underlying collateral.

FHLB Stock

The fair value of FHLB stock approximates the carrying amount based on the redemption provisions of the FHLB. These assets were classified as Level 2.

Rabbi Trust and Deferred Compensation Plan Investments

Rabbi trust and deferred compensation plan investments consisted primarily of cash and cash equivalents, U.S. government agency obligations, equity securities, mutual funds and other exchange-traded funds, and were recorded at fair value and included in other assets. The purpose of these investments is to fund certain executive non-qualified retirement benefits and deferred compensation.

The fair value of other U.S. government agency obligations were estimated using either a matrix or benchmarks. The inputs used include benchmark yields, reported trades, broker/dealer quotes, and issuer spreads. These securities were categorized as Level 2 given the use of observable inputs. The equity securities, mutual funds and other exchange-traded funds were valued based on quoted prices from the market. The equities, mutual funds and exchange-traded funds traded in an active market were categorized as Level 1 as they were valued based upon quoted prices from the market. Mutual funds at net asset value amounted to $56.1 million at March 31, 2025 and $54.1 million at December 31, 2024. There were no redemption restrictions on these mutual funds at the end of any period presented.

Bank-Owned Life Insurance

The fair value of bank-owned life insurance was based upon quotations received from bank-owned life insurance dealers. These assets were classified as Level 2 given the use of observable inputs.

Deposits

The fair value of deposits with no stated maturity, such as noninterest-bearing demand deposits, savings, interest checking accounts, and money market accounts, was equal to their carrying amount. The fair value of time deposits was based on the discounted value of contractual cash flows using current market interest rates. Deposits were classified as Level 2 given the use of observable market inputs.

The fair value estimates of deposits do not include the benefit that results from the low-cost funding provided by the deposit liabilities compared to the cost of borrowing funds in the wholesale market (core deposit intangibles).

FHLB Advances

The fair value of FHLB advances was based on the discounted value of contractual cash flows. The discount rates used are representative of approximate rates currently offered on instruments with similar remaining maturities. FHLB advances were classified as Level 2.

Interest Rate Swap Collateral Funds

The fair value of interest rate swap collateral funds approximates the carrying amount. Interest rate swap collateral funds were classified as Level 2.

Interest Rate Swaps

The fair value of interest rate swaps was determined using discounted cash flow analysis on the expected cash flows of the interest rate swaps. This analysis reflects the contractual terms of the interest rate swaps, including the period of maturity, and uses observable market-based inputs, including interest rate curves and implied volatility. In addition, for customer-related interest rate swaps, the analysis reflects a credit valuation adjustment to reflect the Company’s own non-performance risk and respective counterparty’s non-performance risk in the fair value measurements. The majority of inputs used to value the Company’s interest rate swaps fall within Level 2 of the fair value hierarchy, but the credit valuation adjustments associated with the interest rate swaps utilize Level 3 inputs, such as estimates of current credit spreads to evaluate the likelihood of default by the Company and its counterparties. However, at March 31, 2025 and December 31, 2024, the impact of the Level 3 inputs on the overall valuation of the interest rate swaps was deemed insignificant to the overall valuation. As a result, the interest rate swaps were categorized as Level 2 within the fair value hierarchy.

Risk Participations

The fair value of risk participations was determined based upon the total expected exposure of the derivative which considers the present value of cash flows discounted using market-based inputs and were therefore categorized as Level 2 within the fair value hierarchy. The fair value also included a credit valuation adjustment which evaluates the credit risk of the counterparties by considering factors such as the likelihood of default by the counterparties, its net exposures, the remaining contractual life, as well as the amount of collateral securing the position. The change in value of derivative assets and liabilities attributable to credit risk was not significant during the reported periods.

Foreign Currency Forward Contracts

The fair values of foreign currency forward contracts were based upon the remaining expiration period of the contracts and bid quotations received from foreign exchange contract dealers and were categorized as Level 2 within the fair value hierarchy.

Mortgage Derivatives

The fair value of mortgage derivatives is determined based upon current market prices for similar assets in the secondary market and, therefore are classified as Level 2 within the fair value hierarchy.

Fair Value of Assets and Liabilities Measured on a Recurring Basis

The following tables present the balances of assets and liabilities measured at fair value on a recurring basis as of March 31, 2025 and December 31, 2024:

There were no transfers to or from Level 1, 2 and 3 during the three months ended March 31, 2025 and twelve months ended December 31, 2024.

The Company held no assets or liabilities measured at fair value on a recurring basis using significant unobservable inputs (Level 3) as of March 31, 2025 or December 31, 2024.

Fair Value of Assets and Liabilities Measured on a Nonrecurring Basis

The Company may also be required, from time to time, to measure certain other assets and liabilities on a nonrecurring basis in accordance with GAAP. The following tables summarize the fair value of assets and liabilities measured at fair value on a nonrecurring basis, as of March 31, 2025 and December 31, 2024.

For the valuation of the collateral-dependent loans, the Company relies primarily on third-party valuation information from certified appraisers and values are generally based upon recent appraisals of the underlying collateral, brokers’ opinions based upon recent sales of comparable properties, estimated equipment auction or liquidation values, income capitalization, or a combination of income capitalization and comparable sales. Depending on the type of underlying collateral, valuations may be adjusted by management for qualitative factors such as economic factors and estimated liquidation expenses. The range of these possible adjustments may vary.

Disclosures about Fair Value of Financial Instruments

The estimated fair values and related carrying amounts for assets and liabilities for which fair value is only disclosed are shown below as of the dates indicated:

This summary excludes certain financial assets and liabilities for which the carrying value approximates fair value. For financial assets, these may include cash and due from banks, federal funds sold and short-term investments. For financial liabilities, these may include federal funds purchased. These instruments would all be considered to be classified as Level 1 within the fair value hierarchy. Also excluded from the summary are financial instruments measured at fair value on a recurring and nonrecurring basis, as previously described.

14. Revenue from Contracts with Customers

Revenue from contracts with customers within the scope of ASC 606, Revenue from Contracts with Customers (Topic 606) (“ASC 606”) is recognized when control of goods or services is transferred to the customer, in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods and services. The Company considers the terms of the contract and all relevant facts and circumstances when applying this guidance. The Company measures revenue and timing of recognition by applying the following five steps:

1. Identify the contract(s) with the customers

2. Identify the performance obligations

3. Determine the transaction price

4. Allocate the transaction price to the performance obligations

5. Recognize revenue when (or as) the entity satisfies a performance obligation

The Company accounts for a contract when it has approval and commitment from both parties, the rights of the parties are identified, payment terms are identified, the contract has commercial substance and collectability of consideration is probable.

Performance obligations

The Company’s performance obligations are generally satisfied either at a point in time or over time, as services are rendered. Unsatisfied performance obligations at the report date are not material to the Company’s Consolidated Financial Statements.

A portion of the Company’s noninterest (loss)/income is derived from contracts with customers within the scope of ASC 606. The Company has disaggregated such revenues by type of service, as presented in the table below. These categories reflect how the nature, amount, timing, and uncertainty of revenue and cash flows are affected by economic factors.

Additional information related to each of the revenue streams is further noted below.

Investment Advisory Fees

The Company offers investment management and trust services to individuals, institutions, small businesses and charitable institutions. Each investment management product is governed by its own contract along with a separate identifiable fee schedule unique to that product. The Company also offers additional services, such as estate settlement, financial planning, tax services, and other special services quoted at the customer’s request.

The asset management and/or custody fees are primarily based upon a percentage of the monthly valuation of the principal assets in the customer’s account. Customers are also charged a base fee which is prorated over a twelve-month period. Fees for additional or special services are generally fixed in nature and are charged as services are rendered. All revenue is recognized in correlation to the monthly management fee determinations or as transactional services are provided. Investment advisory fees earned but not yet received amounted to $10.7 million and $5.7 million as of March 31, 2025 and December 31, 2024, respectively.

Deposit Service Charges

The Company offers various deposit account products to its customers governed by specific deposit agreements applicable to either personal customers or business customers. These agreements identify the general conditions and obligations of both parties and include standard information regarding deposit account-related fees.

Deposit account services include providing access to deposit accounts as well as access to the various deposit transactional services of the Company. These transactional services are primarily those that are identified in the standard fee schedule, and include, but are not limited to, services such as overdraft protection, wire transfer, and check collection. The Company may charge monthly fixed service fees associated with the customer having access to the deposit account as well as separate fixed fees associated with and at the time specific transactions are entered into by the customer. As such, the Company considers that its performance obligations are fulfilled when customers are provided deposit account access or when the requested deposit transaction is completed.

Cash management services are a subset of the deposit service charges revenue stream. These services include automated clearing house, or ACH, transaction processing, positive pay, lockbox, and remote deposit services. These services are also governed by separate agreements entered into by the customer. The fee arrangement for these services is structured as a fixed fee per transaction which may be offset by earnings credits. An earnings credit is a discount that a customer receives based upon the investable balance in the applicable covered deposit account(s) for a given month. Earnings credits are only good for the given month. That is, if cash management fees for a given month are less than the month’s earnings credit, the remainder of the credit does not carry over to the following month. Cash management fees are recognized as revenue in the month that the services are provided. Cash management fees earned but not yet received amounted to $1.6 million as of both March 31, 2025 and December 31, 2024 and were included in other assets in the Company’s Consolidated Balance Sheets.

Card Income

The Company provides debit cards to its customers which are authorized and settled through various card payment networks, and in exchange, the Company earns revenue as determined by each payment network’s interchange program. Regardless of the network that is utilized to authorize and settle the payment, the merchant that provides the product or service to the debit card holder is ultimately responsible for the interchange payment to the Company. Debit card processing fees are recognized as card transactions are settled within each network. In addition, the Company receives income for credit card referrals from third party credit card providers, which it offers to its customers. Card income fees earned but not yet received amounted to $0.7 million and $1.2 million as of March 31, 2025 and December 31, 2024, respectively, and were included in other assets in the Company’s Consolidated Balance Sheets.

Other Noninterest Income

The Company earns various types of other noninterest income that have been aggregated into one general revenue stream in the table noted above. Noninterest income in-scope of ASC 606 includes, but is not limited to, the following types of revenue with customers: safe deposit rent, ATM surcharge fees and customer checkbook fees. Individually, these sources of noninterest income are not material.

15. Other Comprehensive Income (Loss)

The following tables present a reconciliation of the changes in the components of other comprehensive income (loss) for the dates indicated including the amount of income tax (expense) benefit allocated to each component of other comprehensive income (loss):

16. 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 has determined that its CODM is its Executive Chair. The Company hasone reportable segment: its banking business, which consists of a full range of banking lending, savings, and small business offerings, and its wealth management and trust operations. The CODM makes operating and resource allocation decisions based upon the results of the Company’s core banking business. The core banking business, which is comprised of the commercial group, consumer group, and wealth management components, is managed by the Company’s Executive Chair and resource allocation decisions are made by the CODM as a single operating segment rather than at the individual component level. Each of these components are conducted and financed through banking activities and operations. The core banking business activities are interrelated and viewed by management as a single operating segment.

The accounting policies of the banking business segment are the same as those described in the summary of significant accounting policies in Note 2, “Summary of Significant Accounting Policies” within the Notes to the Consolidated Financial Statements included in Part II, Item 8 in the Company’s 2024 10-K. The CODM assesses performance of the banking business segment and decides how to allocate resources based upon net income that is reported on the Consolidated Statements of Income as net (loss) income. The measure of segment assets is reported on the Consolidated Balance Sheets as total assets. The CODM uses net income to evaluate income generated from segment assets in deciding whether to reinvest profits into the banking business segment or into other parts of the Company, such as for acquisitions, to pay dividends, or to repurchase outstanding shares. Net income is used to monitor budget versus actual results. The CODM also uses net income in competitive analysis by benchmarking to the Company’s competitors. The competitive analysis along with the monitoring of budgeted versus actual results are used in assessing performance of the segment and in establishing management’s compensation. The Company does not have intra-entity sales.

The CODM uses consolidated profit and loss measures which are presented on the Company’s Consolidated Statements of Income. Therefore, refer to the Consolidated Statements of Income for quantitative information regarding the banking business segment operating results. The segment operating results include certain other segment items which are included in other noninterest expense within the Consolidated Statements of Income. Significant expense items included in the other noninterest expense line include operational losses, which are primarily comprised of debit card and bad check losses, liability insurance expense, and other loan expenses, which are primarily comprised of legal collection fees and certain origination and servicing-related expenses. The CODM reviews such amounts as a whole in their review of segment operating results.
