Accounting Policies [Abstract]
Nature of Business Activities and Significant Accounting Policies	Nature of Business Activities and Significant Accounting Policies Nature of operations Burke & Herbert Financial Services Corp. (“Burke & Herbert”) was organized as a Virginia corporation on September 14, 2022, to serve as the holding company for Burke & Herbert Bank & Trust Company (“the Bank” and, together with Burke & Herbert, the “Company”). Burke & Herbert commenced operations as a bank holding company on October 1, 2022, following a reorganization transaction in which it became the Bank’s holding company. This transaction was treated as an internal reorganization as all shareholders of the Bank became shareholders of Burke & Herbert. In September 2023, Burke & Herbert elected to be a financial holding company. As a financial holding company, Burke & Herbert is subject to regulation and supervision by the Federal Reserve. Burke & Herbert has no material operations and owns 100% of the Bank. The Bank is a Virginia chartered commercial bank that commenced operations in 1852. The Bank is supervised and regulated by the Federal Deposit Insurance Corporation (the “FDIC”) and the Bureau of Financial Institutions of the Virginia State Corporation Commission (the “Virginia BFI”). Merger with Summit Financial Group, Inc. Effective on May 3, 2024 (the “Closing Date”), Burke & Herbert completed its previously announced merger with Summit Financial Group, Inc., a West Virginia corporation (“Summit”), pursuant to the Agreement and Plan of Reorganization and accompanying Plan of Merger dated August 24, 2023, between Burke & Herbert and Summit (the “Merger Agreement”). Below is a description of the nature of the event as of the merger Closing Date. Pursuant to the Merger Agreement, on the Closing Date, (i) Summit merged with and into Burke & Herbert, with Burke & Herbert continuing as the surviving corporation (the “Merger”), and (ii) immediately following the Merger, Summit Community Bank, Inc., a West Virginia chartered bank and a wholly-owned subsidiary of Summit (“SCB”), merged with and into the Bank, with the Bank as the surviving bank. In the Merger, holders of Summit common stock outstanding at the effective time of the Merger received 0.5043 shares of Burke & Herbert common stock for each share of Summit common stock they owned, subject to the payment of cash in lieu of fractional shares. The total aggregate consideration payable in the Merger was approximately 7,405,772 shares of Burke & Herbert Common Stock. Additionally, each share of Summit’s 6.0% Fixed Rate Non-Cumulative Perpetual Preferred Stock, Series 2021 (the “Summit Series 2021 Preferred Stock”) issued and outstanding was converted into the right to receive a share of a newly created series of preferred stock, the Burke & Herbert Series 2021 Preferred Stock (the “Burke & Herbert Series 2021 Preferred Stock”). Summit’s results of operations are included from the Closing Date. The Bank’s primary market area includes northern Virginia and West Virginia, and it has over 75 branches and other commercial loan offices across Delaware, Kentucky, Maryland, Virginia, and West Virginia. The Company’s branch locations accept business and consumer deposits from a diverse customer base. The Company’s deposit products include checking, savings, and term certificate accounts. The Company’s loan portfolio includes commercial and consumer loans, a substantial portion of which are secured by real estate. Basis of Presentation The accompanying consolidated financial statements include Burke & Herbert Financial Services Corp. and its wholly owned subsidiary Burke & Herbert Bank & Trust Company and have been prepared in accordance with generally accepted accounting principles in the United States of America (“GAAP”) for interim financial reporting and with applicable quarterly reporting regulations of the U.S. Securities and Exchange Commission (“SEC”). The accounting and reporting policies of the Company conform to GAAP and reflect practices of the banking industry. They do not include all of the information and notes required by GAAP for complete financial statements.

The consolidated financial statements include the accounts of the Company and the Bank (as its wholly-owned subsidiary). All significant intercompany accounts and transactions between the Company and the Bank have been eliminated. In preparing 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 sheet and reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. In the opinion of management, all adjustments, consisting only of normal recurring adjustments, which are necessary for a fair presentation of the results of operations in these financial statements, have been made. The results of operations for the three and six months ended June 30, 2024, are not necessarily indicative of the results to be expected for any other interim period or for the full year. All December 31, 2023 amounts and disclosures included in this quarterly report were derived from the Company’s audited consolidated financial statements. Certain items in the prior period have been reclassified to conform to the current presentation. These reclassifications had no effect on prior year net income or on shareholders’ equity. Purchased Credit Deteriorated (PCD) Loans The Company has purchased loans, some of which have experienced more than insignificant credit deterioration since origination. PCD loans are loans on nonaccrual status, are greater than 60 days past due at any time since loan origination or have a risk rating of special mention, substandard, doubtful, or loss. PCD loans are recorded at the amount paid. An allowance for credit losses is determined using the same methodology as other loans held for investment. The initial allowance for credit losses determined on a collective basis is allocated to individual loans. The sum of the loan’s purchase price and allowance for credit losses becomes its initial amortized cost basis. The difference between the initial amortized cost basis and the par value of the loan is a noncredit discount or premium, which is amortized into interest income over the life of the loan. Subsequent changes to the allowance for credit losses are recorded through credit loss expense. Goodwill and Other Intangible Assets Goodwill arises from business combinations and is determined as the excess of the fair value of the consideration transferred, plus the fair value of any noncontrolling interests in the acquiree, over the fair value of the net assets acquired and liabilities assumed as of the acquisition date. Goodwill and intangible assets acquired in a business combination and determined to have an indefinite useful life are not amortized, but tested for impairment at least annually or more frequently if events and circumstances exist that indicate that an impairment test should be performed. The Company has selected September 30 as the date to perform the annual impairment test. Intangible assets with finite useful lives are amortized over their estimated useful lives to their estimated residual values. Amortized intangibles must be reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of the long-lived asset (group) might not be recoverable. An impairment loss related to intangible assets with finite useful lives is recognized if the carrying amount of the intangible asset is not recoverable and its carrying amount exceeds its fair value. After the impairment loss is recognized, the adjusted carrying amount of the intangible asset shall be its new accounting basis. Goodwill is the only intangible asset with an indefinite life on our balance sheet. Other intangible assets consists of core deposit intangible assets arising from whole bank and branch acquisitions and is amortized using an accelerated method over their estimated useful lives of seven years. Recently adopted accounting standards In March 2023, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Updated (“ASU”) 2023-02, Investments—Equity Method and Joint Ventures (Topic 323): Accounting for Investments in Tax Credit Structures Using the Proportional Amortization Method . These amendments allow reporting entities to elect to account for qualifying tax equity investments using the proportional amortization method, regardless of the program giving rise to the related income tax credits. The ASU was effective for us January 1, 2024, and did not have a material impact on our consolidated financial statements. In June 2022, the FASB issued ASU 2022-03, Fair Value Measurement (Topic 820): Fair Value Measurement of Equity Securities Subject to Contractual Sale Restrictions . ASU 2022-03 clarifies that a contractual restriction on the sale of an equity security is not considered part of the unit of account of the equity security and, therefore, is not considered in measuring fair value. The ASU was effective for us January 1, 2024, and did not have a material impact on our consolidated financial statements. Pending adoption of new accounting standards In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740) : Improvements to Income Tax Disclosures . The amendments in this ASU require an entity to disclose specific categories in the rate reconciliation and provide additional information for reconciling items that meet a quantitative threshold, which is greater than five percent of the amount computed by multiplying pretax income by the entity’s applicable statutory rate, on an annual basis. Additionally, the amendments in this ASU require an entity to disclose the amount of income taxes paid (net of refunds received) disaggregated by federal, state, and foreign taxes and the amount of income taxes paid (net of refunds received) disaggregated by individual jurisdictions that are equal to or greater than five percent of total income taxes paid (net of refunds received). Lastly, the amendments in this ASU require an entity to disclose income (or loss) from continuing operations before income tax expense (or benefit) disaggregated between domestic and foreign and income tax expense (or benefit) from continuing operations disaggregated by federal, state, and foreign. This ASU is effective for annual periods beginning after December 15, 2024. Early adoption is permitted. The amendments should be applied on a prospective basis; however, retrospective application is permitted. We do not expect the adoption of ASU 2023-09 to have a material impact on our consolidated financial statements. In October 2023, the FASB issued ASU 2023-06, Disclosure Improvements: Codification Amendments in Response to the SEC’s Disclosure Update and Simplification Initiative . This ASU incorporates certain SEC disclosure requirements into the FASB Accounting Standards Codification. The amendments in the ASU are expected to clarify or improve disclosure and presentation requirements of a variety of Codification Topics, allow users to more easily compare entities subject to the SEC’s existing disclosures with those entities that were not previously subject to the requirements, and align the requirements in the Codification with the SEC’s regulations. For entities subject to the SEC’s existing disclosure requirements and for entities required to file or furnish financial statements with or to the SEC in preparation for the sale of or for purposes of issuing securities that are not subject to contractual restrictions on transfer, the effective date for each amendment will be the date on which the SEC removes that related disclosure from its rules. For all other entities, the amendments will be effective two years later. However, if by June 30, 2027, the SEC has not removed the related disclosure from its regulations, the amendments will be removed from the Codification and not become effective for any entity. We do not expect the adoption of ASU 2023-06 to have a material impact on our consolidated financial statements.

The following table shows the gross unrealized losses and fair value of the Company’s securities with unrealized losses aggregated by investment category and length of time that individual securities have been in a continuous unrealized loss position at June 30, 2024, and December 31, 2023.

If these situations apply, the guidance requires the Company to reduce the security's amortized cost basis down to its fair value through earnings. The Company also evaluates the unrealized losses on AFS securities to determine if a security's decline in fair value below its amortized cost basis is due to credit factors. The evaluation is based upon factors such as the creditworthiness of the underlying borrowers, performance of the underlying collateral, if applicable, and the level of credit support in the security structure. Management also evaluates other factors and circumstances that may be indicative of a decline in the fair value of the security due to a credit factor. This includes, but is not limited to, an evaluation of the type of security, length of time and extent to which the fair value has been less than cost, and near-term prospects of the issuer. If this assessment indicates that a credit loss exists, the present value of the expected cash flows of the security is compared to the amortized cost basis of the security. If the present value of the cash flows expected to be collected is less than the amortized cost, an allowance for credit losses (“ACL”) is recorded for the credit loss, limited by the amount that the fair value is less than the amortized cost basis under the current expected credit loss (“CECL”) standard, and declines due to non-credit factors are recorded in accumulated other comprehensive income (“AOCI”), net of taxes. If a credit loss is recognized in earnings, subsequent improvements to the expectation of collectability will be recognized through the ACL. If the fair value of the security increases above its amortized cost, the unrealized gain will be recorded in accumulated other comprehensive income, net of taxes, in the consolidated statements of financial condition. Prior to implementation of the CECL standard, unrealized losses caused by a credit event would require the direct write-down of the AFS security through the other-than-temporary impairment approach. The Company did not record an ACL on the AFS securities as of June 30, 2024 or December 31, 2023. The Company considers the unrealized losses on the AFS securities to be related to fluctuations in market conditions, primarily interest rates, and not reflective of deterioration in credit. The Company had 445 securities in an unrealized loss position as of June 30, 2024. The Company has evaluated AFS securities in an unrealized loss position for credit-related impairment at June 30, 2024, and concluded no impairment existed based on a combination of factors, which included: (1) the securities are of high credit quality, (2) unrealized losses are primarily the result of market volatility and increases in market interest rates, (3) the contractual terms of the investments do not permit the issuer(s) to settle the securities at a price less than the par value of each investment, (4) issuers continue to make timely principal and interest payments, and (5) the Company does not intend to sell any of the investments and the accounting standard of “more likely than not” has not been met for the Company to be required to sell any of the investments before recovery of its amortized cost basis. As such, there was no ACL on AFS securities at June 30, 2024. Securities of U.S. Treasury and Federal Agencies and Federal Agency Mortgage (Residential and Commercial) Backed Securities At June 30, 2024, the unrealized losses associated with 11 U.S. Treasuries and Government Agency securities, 16 Residential Mortgage Backed – Agency securities, and 15 Commercial Mortgage Backed – Agency securities were generally driven by changes in interest rates and not due to credit losses given the explicit or implicit guarantees provided by the U.S. government. Therefore, the Company has concluded that the unrealized losses for these securities do not require an ACL at June 30, 2024. Securities of U.S. States and Municipalities At June 30, 2024, the unrealized losses associated with 257 State and Municipal securities were primarily caused by changes in interest rates and not the credit quality of the securities. These securities are investment grade and were generally underwritten in accordance with our own investment standards prior to the decision to purchase, without relying on a bond insurer’s guarantee in making the investment decision. These securities will continue to be monitored as part of our ongoing impairment analysis but are expected to perform, even if the rating agencies reduce the credit rating of the bond insurers. As a result, we expect to recover the entire amortized cost basis of these securities. Therefore, the Company has concluded that the unrealized losses for these securities do not require an ACL at June 30, 2024. Residential & Commercial Mortgage Backed – Non-Agency Securities At June 30, 2024, the unrealized losses associated with 84 Residential Mortgage Backed – Non-Agency securities and 31 Commercial Mortgage Backed – Non-Agency securities were generally driven by changes in interest rates, credit spreads, and projected collateral losses. We assess for credit impairment by estimating the present value of expected cash flows. The key assumptions for determining expected cash flows include default rates, loss severities, and/or prepayment rates. Based on our assessment of the expected credit losses and the credit enhancement level of the securities, we expect to recover the entire amortized cost of these securities. Therefore, the Company has concluded that the unrealized losses for these securities do not require an ACL at June 30, 2024. Asset-Backed Securities At June 30, 2024, the unrealized losses associated with 19 Asset-Backed securities were generally driven by changes in interest rates, credit spreads, and projected collateral losses. We assess for credit impairment by estimating the present value of expected cash flows. The key assumptions for determining expected cash flows include default rates, loss severities, and/or prepayment rates. Based on our assessment of the expected credit losses and the credit enhancement level of the securities, we expect to recover the entire amortized cost of these securities. Therefore, the Company has concluded that the unrealized losses for these securities do not require an ACL at June 30, 2024. Other Securities At June 30, 2024, the unrealized losses associated with 12 securities were primarily driven by interest rates and not the credit quality of the securities. These investments were underwritten in accordance with our own investment standards prior to the decision to purchase, without relying on a bond insurer’s guarantee in making the investment decision. Based on our assessment of the expected credit losses, we expect to recover the entire amortized cost basis of the securities. Therefore, the Company has concluded that the unrealized losses for these securities do not require an ACL at June 30, 2024. Restricted stock, at cost The Company’s investment in Federal Home Loan Bank (“FHLB”) stock totaled $15.1 million and $5.9 million at June 30, 2024, and December 31, 2023, respectively. FHLB stock is generally viewed as a long-term investment and as a restricted investment security, which is carried at cost, because there is no market for the stock other than the FHLB or member institutions. Therefore, when evaluating FHLB stock for impairment, its value is based on the ultimate recoverability of the par value rather than by recognizing temporary declines in value. The Company does not consider this investment to be impaired at June 30, 2024, and no impairment has been recognized. FHLB stock is included in a separate line item Restricted stock, at cost on the Consolidated Balance Sheets and is not part of the Company’s AFS securities portfolio. The Company’s Restricted stock line item on the Consolidated Balance Sheets also includes an investment in Community Bankers’ Bank, totaling $50 thousand at both June 30, 2024, and December 31, 2023, which is carried at cost and is not impaired at June 30, 2024.

Loans	Loans The Company’s loan portfolio segments, as reported in the tables below, include (i) commercial real estate, (ii) owner-occupied commercial real estate, (iii) acquisition, construction & development, (iv) commercial & industrial, (v) single family residential (1-4 units), and (vi) consumer non-real estate and other. The risks associated with lending activities differ among the various loan segments and are subject to the impact of changes in interest rates, market conditions of collateral securing the loans, and general economic conditions. • Commercial real estate loans carry risk associated with either the net operating income generated from the lease of the real estate collateral or income generated from the sale of the collateral. Other risk factors include the credit-worthiness of the sponsor and the value of the collateral. • Owner-occupied commercial real estate loans carry risk associated with the operations of the business that occupies the property and the value of the collateral. • Acquisition, construction & development loans carry risk associated with the credit-worthiness of the borrower, project completion within budget, sale after completion, and the value of the collateral. • Commercial & industrial loans carry the risk associated with the operations of the business and the value of the collateral, if any. • Single family residential (1-4 units) loans for consumer purposes carry risk associated with the continued credit-worthiness of the borrower and the value of the collateral. Single family residential (1-4 units) loans for investment purpose carry risk associated with the continued credit-worthiness of the borrower, the value of the collateral, and either the net operating income generated from the lease of the real estate collateral or income generated from the sale of the collateral. • Consumer non-real estate and other loans, which includes overdrafts, carry risk associated with the credit-worthiness of the borrower and the value of the collateral, if any. Loan balances as of June 30, 2024, and December 31, 2023, by portfolio segment were as follows (in thousands): June 30, 2024 December 31, 2023 Commercial real estate $ 2,543,668 $ 1,309,084 Owner-occupied commercial real estate 626,375 131,381 Acquisition, construction & development 479,937 49,091 Commercial & industrial 499,892 67,847 Single family residential (1-4 units) 1,219,984 527,980 Consumer non-real estate and other 246,868 2,373 Loans, gross 5,616,724 2,087,756 Allowance for credit losses (68,017) (25,301) Loans, net $ 5,548,707 $ 2,062,455 Net deferred loan fees included in the above loan categories totaled $3.2 million and $3.5 million at June 30, 2024, and December 31, 2023, respectively.

Allowance for Credit Losses

Allowance for Credit Losses	6 Months Ended

Credit Loss [Abstract]
Allowance for Credit Losses	Allowance for Credit Losses On January 1, 2023, the Company adopted the CECL methodology as required under Accounting Standards Codification (“ASC”) 326. The measurement of expected credit losses under the CECL methodology is applicable to financial assets measured at amortized cost, including loan receivables. All information presented as of June 30, 2024, is in accordance with ASC 326. The Company’s ACL is calculated quarterly, with any adjustment recorded to the provision for credit losses in the Consolidated Statement of Income. Management calculates the quantitative portion of collectively evaluated loans for all loan categories using the weighted average remaining maturity (“WARM”) method. For purposes of estimating the Company’s ACL, management generally evaluates collectively evaluated loans by federal call code in order to group loans with similar risk characteristics. Loans that do not share similar risk characteristics are evaluated on an individual loan basis and are excluded from the collective evaluation for the ACL. Loans identified to be individually evaluated under CECL include loans on non-accrual status and may include accruing loans that do not share similar risk characteristics to other accruing loans that are collectively evaluated on a loan pool basis. A specific reserve analysis may be applied to the individually evaluated loans, which considers collateral value, an observable market price, or the present value of the expected future cash flows. A specific reserve is assigned if the measured value of the loan using one of the before mentioned methods is less than the carrying value of the loan. Based on management’s analysis, adjustments may be applied for additional factors impacting the risk of loss in the loan portfolio beyond the information that is used to calculate a reasonable and supportable forecast and a reversion period forecast on collectively evaluated loans. Management may consider an additional or reduced reserve as warranted through qualitative risk factors based on the current and expected conditions as measured in supplemental information relative to the macroeconomic variable loss drivers used to calculate a reasonable and supportable forecast and a reversion period forecast.

The Company analyzes loans individually by classifying the loans by credit risk. The Company internally grades all commercial loans at the time of origination. In addition, the Company performs an annual review on the top twenty-five non-homogenous commercial loan relationships as measured by total Company exposure to each borrower. The Company uses the following definitions for credit risk classifications: Pass : These include satisfactory loans that have acceptable levels of risk. Special Mention : Loans classified as special mention have a potential credit weakness that deserves management’s close attention. If left uncorrected, these potential weaknesses may result in deterioration of the repayment prospects for the loan or of the institution’s credit position at some future date. Substandard : Loans classified as substandard have a well-defined weakness or weaknesses that jeopardize the orderly liquidation of debt. Loans classified as substandard are inadequately protected by sound net worth, payment capacity of the borrower, or of the collateral pledged. If weaknesses go uncorrected, there is potential for partial loss of principal and/or interest. Doubtful : Loans classified as doubtful have all the weaknesses inherent in those classified as substandard, with the added characteristic that the weaknesses make collection or liquidation in full, on the basis of currently existing facts, conditions, and values, highly questionable and unlikely. Loss : Loans classified as a loss are considered to be uncollectible and cannot be justified to continue as viable assets. While there may be the possibility of some recovery in the future, it is not practical or desirable to defer writing off these loans at the present time. The Company has a portfolio of smaller homogenous loans that are not individually risk rated that are included within the single family residential and consumer non-real estate and other loan classes. Generally, these loan classes are rated as “Pass” unless these loans are on non-accrual and are then classified as substandard.

ASU 2022-02 eliminates the troubled debt restructuring (“TDR”) accounting model and requires that the Company evaluate, based on the accounting for loan modifications, whether the borrower is experiencing financial difficulty, and the modification results in a more-than-insignificant direct change in the contractual cash flows and represents a new loan or a continuation of an existing loan. This change required all loan modifications to be accounted for under the general loan modification guidance in ASC 310-20, Receivables — Nonrefundable Fees and Other Costs, and subjects entities to new disclosure requirements on loan modifications to borrowers experiencing financial difficulty. The Company may modify loans to borrowers experiencing financial difficulty by providing principal forgiveness, term extension, interest rate reduction, or an other-than-insignificant payment delay. When principal forgiveness is provided, the amount of forgiveness is charged off against the ACL. The Company may also provide multiple types of modifications on an individual loan. For the three and six months ended June 30, 2024, and for the year ended, December 31, 2023, the Company did not extend any modifications to borrowers experiencing financial difficulty that had a more-than-insignificant direct change in the contractual cash flows of the loan.

The average balance outstanding during the six months ending June 30, 2024, and the year ending December 31, 2023, was $334.8 million and $293.9 million, respectively. The Company has a finance lease liability that is not included in these balances - see Note 7 - Leased Property for a discussion of this liability that is included in the accrued interest and other liabilities line in the Consolidated Balance Sheets. The Company has available secured lines of credit with the Federal Reserve Bank of Richmond, such as the Borrower-In-Custody program, the FHLB of Atlanta, and unsecured federal funds lines of credit from correspondent banking relationships. Through these sources, the Company has unused capacity of $2.2 billion in remaining borrowing capacity as of June 30, 2024. The advances on credit lines are secured by both securities and loans. The lendable collateral value of securities and loans pledged against available lines of credit as of June 30, 2024, and December 31, 2023, was $1.3 billion and $797.8 million, respectively. As of June 30, 2024, all of the Company’s borrowings will mature within one calendar year. The contractual maturities of these borrowings, which all occur within one year of the reporting date, are as follows as of June 30, 2024, (in thousands): Due in 2024 $ 265,161 Due in 2025 20,000 Total $ 285,161 Long-term borrowings Subordinated Debentures As part of the Merger, Burke & Herbert assumed $75 million of subordinated debentures, that were fair valued at $61.5 million with a $13.5 million discount being amortized into interest expense over the stated maturity. As of June 30, 2024, the net balance was $62.4 million. The subordinated debt qualifies as Tier 2 capital under Federal Reserve Board guidelines, until the debt is within 5 years of its maturity; thereafter, the amount qualifying as Tier 2 capital is reduced 20% each year until maturity. The subordinated debentures were issued in the fourth quarter of 2021. This subordinated debt bears interest at a fixed rate of 3.25% per year, from acquisition date to, but excluding, December 1, 2026, payable semi-annually in arrears. From and including, December 1, 2026 to, but excluding, the maturity date or earlier redemption date, the interest rate will reset quarterly at a variable rate equal to the then current three-month term Secured Overnight Financing Rate (“SOFR”), as published by the Federal Reserve Bank of New York, plus 230 basis points, payable quarterly in arrears. This debt has a 10-year term, and generally, is not prepayable by us within the first 5 years from issuance, which was fourth quarter 2021. Through the Merger, Burke & Herbert also assumed $30 million of subordinated debentures that were fair valued at $30 million with a $0.2 million discount being amortized into interest expense over the stated maturity. As of June 30, 2024, the net balance was $30 million.

The subordinated debentures were issued in the third quarter of 2020. This subordinated debt bears interest at a fixed rate of 5.00% per year from the date of assumption to, but excluding, September 30, 2025, payable quarterly in arrears. From and including September 30, 2025, to, but excluding, the maturity date or earlier redemption date, the interest rate will reset quarterly at a variable rate equal to the then current three-month term SOFR plus 487 basis points, payable quarterly in arrears. This debt has a 10-year term, and generally, is not prepayable by us within the first 5 years from issuance, which was third quarter 2020. Subordinated Debentures Owed to Unconsolidated Subsidiary Trusts As part of the Merger, Burke & Herbert became the sponsor for SFG Capital Trust I, SFG Capital Trust II, and SFG Capital Trust III. For each of these trusts, 100% of the common equity is owned by us. SFG Capital Trust I issued $3.5 million in capital securities and $109 thousand in common securities and invested the proceeds in $3.61 million of debentures, which were assumed by Burke & Herbert in the Merger.

Regulatory Capital Matters

Regulatory Capital Requirements under Banking Regulations [Abstract]
Regulatory Capital Matters	Regulatory Capital Matters Banks and financial holding companies are subject to regulatory capital requirements administered by federal banking agencies. Capital adequacy guidelines and, additionally for banks, “prompt corrective action” regulations involve quantitative measures of assets, liabilities, and certain off-balance sheet items calculated under regulatory accounting practices. Capital amounts and classifications are also subject to qualitative judgments by regulators. Failure to meet capital requirements can initiate regulatory action. The net unrealized gain or loss on AFS securities is not included in computing regulatory capital. Management believes as of June 30, 2024, the Company and the Bank meet all capital adequacy requirements to which they are subject. “Prompt corrective action” regulations provide five classifications: “well capitalized”, “adequately capitalized”, “undercapitalized”, “significantly undercapitalized”, and “critically undercapitalized”, although these terms are not used to represent overall financial condition. If “adequately capitalized”, regulatory approval is required to accept brokered deposits. If “undercapitalized”, capital distributions are limited, as is asset growth and expansion, and capital restoration plans are required. As of June 30, 2024, and December 31, 2023, the most recent notification from the FDIC categorized the Bank as “well capitalized” under the regulatory framework for “prompt corrective action”. The following table presents the actual and required capital amounts and ratios for the Company and the Bank at June 30, 2024, and December 31, 2023 (in thousands except for ratios): Actual Minimum Required Capital - Basel III Minimum Required to be Well Capitalized Amount Ratio Amount Ratio Amount Ratio As of June 30, 2024 Total Capital to risk weighted assets Consolidated $ 889,854 13.91 % $ 671,804 ≥ 10.5% $ 639,813 N/A Burke & Herbert Bank & Trust 864,853 13.53 671,181 ≥ 10.5 639,220 ≥ 10.0 Tier 1 (Core) Capital to risk weighted assets Consolidated 725,595 11.34 543,841 ≥ 8.5 511,850 N/A Burke & Herbert Bank & Trust 792,772 12.40 543,337 ≥ 8.5 511,376 ≥ 8.0 Common Tier 1 (CET 1) to risk-weighted assets Consolidated 698,296 10.91 447,869 ≥ 7.0 415,878 N/A Burke & Herbert Bank & Trust 792,772 12.40 447,454 ≥ 7.0 415,493 ≥ 6.5 Tier 1 (Core) Capital to average assets (leverage ratio) Consolidated 725,595 9.04 320,911 ≥ 4.0 401,139 N/A Burke & Herbert Bank & Trust 792,772 9.89 320,638 ≥ 4.0 400,798 ≥ 5.0 As of December 31, 2023 Total Capital to risk weighted assets Consolidated $ 443,799 17.88 % $ 260,694 ≥ 10.5% $ 248,280 N/A Burke & Herbert Bank & Trust 442,414 17.82 260,626 ≥ 10.5 248,215 ≥ 10.0 Tier 1 (Core) Capital to risk weighted assets Consolidated 418,244 16.85 211,038 ≥ 8.5 198,624 N/A Burke & Herbert Bank & Trust 416,859 16.79 210,983 ≥ 8.5 198,572 ≥ 8.0 Common Tier 1 (CET 1) to risk-weighted assets Consolidated 418,244 16.85 173,796 ≥ 7.0 161,382 N/A Burke & Herbert Bank & Trust 416,859 16.79 173,751 ≥ 7.0 161,340 ≥ 6.5 Tier 1 (Core) Capital to average assets (leverage ratio) Consolidated 418,244 11.31 147,965 ≥ 4.0 184,957 N/A Burke & Herbert Bank & Trust 416,859 11.27 147,986 ≥ 4.0 184,982 ≥ 5.0

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivatives	Derivatives The Company utilizes interest rate swap agreements as part of its asset liability management strategy to help manage its interest rate risk position. The notional amount of the interest rate swaps does not represent amounts exchanged by the parties. The amount exchanged is determined by reference to the notional amount and the other terms of the individual interest rate swap agreements. Cash flow hedges of interest rate risk The Company’s objective in using interest rate derivatives is to add stability to interest income and to manage its exposure to interest rate movements. To accomplish this objective, the Company primarily uses interest rate swaps, caps, and floors as part of its interest rate risk management strategy. Interest rate swaps designated as cash flow hedges involve the receipt of variable-rate amounts from a counterparty in exchange for the Company making fixed-rate payments over the life of the agreements without exchange of the underlying notional amount. Other interest rate swaps designated as cash flow hedges involve the receipt of fixed-rate amounts from a counterparty in exchange for the Company making variable-rate payments over the life of the agreements without exchange of the underlying notional amount. During 2024, such derivatives were used to hedge the variable cash flows associated with variable-rate assets. For derivatives designated and that qualify as cash flow hedges of interest rate risk, the gain or loss on the derivative is recorded in AOCI and subsequently reclassified into interest expense or interest income in the same period(s) during which the hedged transaction affects earnings. During the next twelve months, the Company estimates that an additional $2.8 million will be reclassified as a reduction to interest expense. Derivatives not designated as hedges The Company enters into interest rate swaps with its loan customers to facilitate their financing requests. Upon entering into swaps with our loan customers, the Company will enter into corresponding offsetting derivatives with third parties. These derivatives represent economic hedges and do not qualify as hedges for accounting. These back-to-back interest rate swaps are reported at fair value in “other assets” and “other liabilities” in the Company’s Consolidated Balance Sheets.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies Credit extension commitments The Company’s financial statements do not reflect various financial instruments which arise in the normal course of business and which involve elements of credit risk, interest rate risk, and liquidity risk. These financial instruments include commitments to extend credit (e.g., revolving lines of credit) and commercial letters of credit. Many of our lending relationships contain both funded and unfunded elements. The funded portion is reflected on our balance sheet. The unfunded portion of these commitments is not recorded on our balance sheet until a draw is made under the loan facility. Since many of our commitments to extend credit may expire without being drawn upon, the total commitment amounts do not necessarily represent future cash flow requirements. A summary of the contractual amounts of the Company’s financial instruments outstanding at June 30, 2024, and December 31, 2023, is as follows (in thousands): June 30, 2024 December 31, 2023 Commitments to extend credit $ 1,091,678 $ 278,923 Commercial letters of credit 68,965 10,718 Commitments to extend credit and commercial letters of credit both include exposure to some credit loss in the event of non-performance of the customer. The Company’s credit policies and procedures for credit commitments and financial guarantees are the same as those for extensions of credit that are recorded on the Consolidated Balance Sheets. Many of these instruments have fixed maturity dates, and many of them will expire without being drawn upon; accordingly, they do not generally present any significant liquidity risk to the Company. Allowance for credit losses - off-balance-sheet credit exposures The Company recorded a provision for credit losses on unfunded commitments of $3.8 million for the three and six months ended June 30, 2024. The Company recorded a recapture of credit losses on unfunded commitments of $96.0 thousand and $104.0 thousand for the three and six months ended June 30, 2023. The ACL on off-balance-sheet credit totaled $4.1 million and $254.2 thousand as of June 30, 2024 and December 31, 2023, and is included in accrued interest and other liabilities on the accompanying Consolidated Balance Sheets. Litigation The Company is a party to litigation, claims, and proceedings arising in the normal course of business that are ordinary and routine to the nature of the Company’s business and operations. Management, after consultation with legal counsel, believes that the liabilities, if any, arising from any currently pending or threatened litigation, claims, or proceedings will not be material to the Company’s financial position.

Fair Value Measurements

Fair Value Disclosures [Abstract]
Fair Value Measurements	Fair Value Measurements Determination of Fair Value Fair value is the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. There are three levels of inputs that may be used to measure fair values: Level 1 – Quoted prices (unadjusted) for identical assets or liabilities in active markets that the entity has the ability to access as of the measurement date. Level 2 – Significant other observable inputs other than Level 1 prices such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data. Level 3 – Significant unobservable inputs that reflect our own assumptions that market participants would use in pricing an asset or liability. In instances in which multiple levels of inputs are used to measure fair value, hierarchy classification is based on the lowest level input that is significant to the fair value measurement in its entirety. The Company’s assessment of the significance of a particular input to the fair value measurement in its entirety requires judgment and considers factors specific to the asset or liability. The Company used the following methods and significant assumptions to estimate fair value: Investment securities The fair values for investment securities are determined by quoted market prices, if available (Level 1). For securities where quoted prices are not available, fair values are calculated based on market prices of similar securities (Level 2), using matrix pricing. Matrix pricing is a mathematical technique commonly used to price debt securities without relying exclusively on quoted prices for the specific securities but rather by relying on securities’ relationship to other benchmark quoted securities (Level 2 inputs). For securities where quoted prices or market prices of similar securities are not available, fair values are calculated using discounted cash flows or other market indicators (Level 3). Equity Investments Equity investments are recorded at fair value on a recurring basis, with changes in fair value reported in net income. Through the Merger, at June 30, 2024, we acquired an investment in an S&P 500 index mutual fund that is actively traded on an exchange, and we classify it as Level 1. Through the Merger, we acquired perpetual preferred stock of a bank holding company issued in October 2022 in a private offering. The perpetual preferred stock does not trade on an exchange or in an active over-the-counter market; therefore, we estimate its fair value using the present value of its future cash flows using observed discount rates of similar publicly-traded securities, adjusted for a liquidity premium. We classify the perpetual preferred stock as Level 2. Equity securities without readily determinable fair values are carried at cost, minus impairment, if any, plus or minus changes resulting from observable price changes in orderly transactions for an identical or similar investment. Such equity securities are included in Equity Investments on the accompanying consolidated balance sheets. Derivatives The fair values of derivatives are based on valuation models using observable market data as of the measurement date (Level 2). The Company has contracted with a third-party vendor to provide valuations for interest rate swaps using standard swap valuation techniques. The Company has considered counterparty credit risk in the valuation of its interest rate swap assets and has considered its own credit risk in the valuation of its interest rate swap liabilities. The Company recognizes interest rate lock commitments at fair value. Fair value of interest rate lock commitments is based on the price of underlying loans obtained from an investor for loans that will be delivered on a best effort basis (Level 2). Loans held-for-sale, at fair value The fair value of loans held-for-sale is determined using quoted prices for similar assets, adjusted for specific attributes of that loan (Level 2). These loans currently consist of one-to-four family residential loans originated for sale in the secondary market. Assets and liabilities measured at fair value on a recurring basis are summarized below (in thousands): Fair Value Measurements at June 30, 2024, Using: Quoted Prices in Active Markets for Identical Assets Significant Other Observable Inputs Significant Unobservable Inputs (Level 1) (Level 2) (Level 3) Total Financial assets Investment Securities U.S. Treasuries and government agencies $ 147,430 $ — $ — $ 147,430 Obligations of states and municipalities — 637,754 — 637,754 Residential mortgage backed - agency — 54,168 — 54,168 Residential mortgage backed - non-agency — 267,313 — 267,313 Commercial mortgage backed - agency — 35,042 — 35,042 Commercial mortgage backed - non-agency — 159,363 — 159,363 Asset-backed — 76,952 — 76,952 Other — 36,848 — 36,848 Total investment securities available-for-sale $ 147,430 $ 1,267,440 $ — $ 1,414,870 Loans held-for-sale, at fair value $ — $ 3,268 $ — $ 3,268 Equity investments $ 7,351 $ 4,671 $ — $ 12,022 Derivatives $ — $ 1,954 $ — $ 1,954 Financial liabilities Derivatives $ — $ 532 $ — $ 532 Fair Value Measurements at December 31, 2023, Using: Quoted Prices in Active Markets for Identical Assets Significant Other Observable Inputs Significant Unobservable Inputs (Level 1) (Level 2) (Level 3) Total Financial assets Investment Securities U.S. Treasuries and government agencies $ 179,071 $ — $ — $ 179,071 Obligations of states and municipalities — 463,203 — 463,203 Residential mortgage backed - agency — 42,238 — 42,238 Residential mortgage backed - non-agency — 266,031 — 266,031 Commercial mortgage backed - agency — 34,885 — 34,885 Commercial mortgage backed - non-agency — 177,061 — 177,061 Asset-backed — 77,936 — 77,936 Other — 8,014 — 8,014 Total investment securities available-for-sale $ 179,071 $ 1,069,368 $ — $ 1,248,439 Loans held-for-sale, at fair value $ — $ 1,497 $ — $ 1,497 Derivatives $ — $ 1,063 $ — $ 1,063 Financial liabilities Derivatives $ — $ 2,045 $ — $ 2,045 The following describes the valuation techniques used by the Company to measure certain assets recorded at fair value on a non-recurring basis in the financial statements: Collateral dependent loans Loans for which the borrower is experiencing financial difficulty and repayment is dependent upon the operation or sale of collateral, are considered collateral dependent. For collateral-dependent loans, the fair value is measured based on the value of the collateral securing the loans, less estimated costs of disposal. Collateral may be in the form of real estate or business assets, including equipment, inventory, and accounts receivable. The vast majority of the collateral underlying collateral dependent loans is real estate, the fair value of which is measured through an appraisal. The appraisals of the collateral supporting collateral dependent loans may utilize a single valuation approach or a combination of approaches, including comparable sales and the income approach. Any fair value adjustments are recorded in the period incurred as provision for credit losses on the Consolidated Statements of Income. Non-real estate collateral may be valued using an appraisal, net book value per the borrower’s financial statements, or aging reports, adjusted or discounted based on management’s historical knowledge, changes in market conditions from the time of the valuation, and management’s expertise and knowledge of the client and client’s business. Other real estate owned Assets acquired through foreclosure or other proceedings are initially recorded at fair value less costs to sell when acquired, establishing a new cost basis. The fair value of foreclosed properties is determined on a nonrecurring basis generally utilizing current appraisals performed by an independent, licensed appraiser applying an income or market value approach using observable market data. Updated appraisals of foreclosed properties are generally obtained if the existing appraisal is more than 18 months old or more frequently if there is a known deterioration in value. However, if a current appraisal is not available, the original appraised value is discounted, as appropriate, to compensate for the estimated depreciation in the value of the real estate since the date of its original appraisal. Such discounts are generally estimated based upon management’s knowledge of sales of similar property within the applicable market area and its knowledge of other real estate market-related data as well as general economic trends. Upon foreclosure, any fair value adjustment is charged against the allowance for credit losses on loans. Subsequent fair value adjustments are recorded in the period incurred and included in other noninterest expense in the consolidated statements of income.

Share-Based Payment Arrangement [Abstract]
Share-Based Compensation	Share-Based Compensation The Company has a share-based incentive plan described below that allows it to offer a variety of equity compensation awards subject to approval. Total compensation cost that has been charged against income for the share-based awards granted was $937.6 thousand and $607.2 thousand for the three months ended June 30, 2024, and June 30, 2023, respectively. The total income tax benefit was $196.9 thousand and $127.5 thousand for the three months ended June 30, 2024, and June 30, 2023, respectively. Total compensation cost that has been charged against income for the share-based awards granted was $1.4 million and $1.2 million for the six months ended June 30, 2024, and June 30, 2023, respectively. The total income tax benefit was $291.5 thousand and $249.4 thousand for the six months ended June 30, 2024, and June 30, 2023, respectively. 2019 Stock Incentive Plan In 2019, the Company’s Stock Incentive Plan (“2019 SIP”) was approved by the Bank’s Board of Directors. The 2019 SIP provides for the issuance of share-based awards to directors and employees of the Company. The 2019 SIP authorized 240,000 units to be issued, and the Company’s practice is using authorized unissued shares to satisfy these share-based awards. Each unit represents a contingent right to receive one common share or an equivalent amount of cash, or a combination of the two, at the discretion of the Company. Currently, we have a sufficient number of authorized unissued shares to satisfy all outstanding equity awards. Under the 2019 SIP, the Company has issued restricted stock unit (“RSU”) awards that are both time-based and performance-based. Each RSU award will indicate the number of shares, the conditions (e.g., service, performance, and/or a combination), and the grant date. Compensation expense is recognized over the vesting period of the awards based on the fair value of the award at grant date. 2023 Stock Incentive Plan In 2023, a new stock incentive plan (“2023 SIP”) was approved by the Company’s Board of Directors and shareholders. Upon the 2023 SIP’s shareholder approval date of March 30, 2023, no further share-based awards will be issued under the 2019 SIP. The 2023 SIP provides for the issuance of share-based awards to directors and employees of the Company. The 2023 SIP authorized the issuance of 250,000 shares, subject to an annual increase in available shares. A total of 48,450 and 24,705 shares were issued during the six months ended June 30, 2024, and June 30, 2023, respectively. For time-based RSUs, the fair value was determined by using the closing stock price on the date prior to the grant date. These RSUs vest over three The Board, from time to time, approves performance-based RSU awards that may be earned between a three The fair value for performance-based RSU awards was determined by using a Monte Carlo simulation analysis to estimate the achievement of the market capitalization target determined by the Board of Directors. The Monte Carlo simulation analysis required the following inputs: (1) expected term, (2) expected volatility, (3) risk-free rate, and (4) dividend yield. The expected term was based on the stated performance period. Management used the expected volatility from a peer group. The risk-free interest rate is based on the U.S. Treasury yield curve over the performance period. The dividend yield assumption was based on historical and anticipated dividend payouts. The following is a summary of all the Company’s RSU awards issued under both the 2019 SIP and 2023 SIP: Non-vested Shares Shares Weighted-Average Grant-Date Fair Value Non-vested at December 31, 2023 143,585 $ 51.21 Granted 48,450 51.14 Vested (103,560) 46.87 Forfeited (600) 73 Non-vested at June 30, 2024 87,875 $ 56.15 As of June 30, 2024, there was $3.3 million of total unrecognized compensation costs related to non-vested shares granted under the 2019 SIP. The cost is expected to be recognized over a weighted average period of 1.86 years. 2023 Employee Stock Purchase Plan In 2023, a new employee stock purchase plan (“2023 ESPP”) was approved by the Company’s Board of Directors and shareholders. Upon the 2023 ESPP’s shareholder approval date of March 30, 2023, the 2023 ESPP reserved 250,000 shares of common stock for issuance to employees. At June 30, 2024, 243,620 shares were available to be issued. Whole shares are sold to participants in the 2023 ESPP at 85% of the lower of the stock price at the beginning or end of each semi-annual offering period that began on September 1, 2023. Eligible employees may purchase shares in an amount that does not exceed the lesser of the IRS limit of $25,000 or 15% of their annual salary. The following table presents information for the 2023 ESPP at the end of June 30, 2024: June 30, 2024 Shares purchased 6,380 Weighted average price of shares purchased $ 43.11 Compensation expense recognized (in 000's) 81.1 Stock Appreciation Rights (“SAR”) Upon completion of the Merger and as a part of the Merger Agreement, Burke & Herbert assumed SAR awards that had been issued to existing employees that would continue with the same terms and conditions adjusted for the exchange ratio of 0.5043. As part of the Merger, a significant portion of SAR awards accelerated their vesting and thus did not require any future service component. Management used the Black-Scholes option-pricing model to fair value these accelerated SAR awards and included this value as part of the purchase price consideration discussed in Note 16 - Business Combination . The Company also used the Black-Scholes option-pricing model to fair value the non-accelerated SAR awards that were not fully vested. The SAR awards that have been assumed by the Company, were issued in 2019, 2021, and 2023, and these SAR awards become exercisable ratably over seven years (14.3% per year) and contractually expire ten years after the grant date. Upon completion of the Merger, the Company determined the fair value per SAR using the following assumptions: 2019 SAR 2021 SAR 2023 SAR # of years to full vesting 7 years 7 years 7 years # of awards unvested as of June 30, 2024 3,202 17,322 25,921 Fair value $ 14.89 $ 16.92 $ 14.56 Risk-free interest rate 4.51 % 4.32 % 4.14 % Expected dividend yield 3.95 % 3.95 % 3.95 % Expected common stock volatility 32.56 % 32.56 % 32.56 % Expected contractual life (in years) 4.77 7.20 8.77 A summary of SAR and option activity during the six months ended June 30, 2024, is as follows: Weighted Average Dollars in thousands, expect per share information SARs Aggregate Fair Value Remaining Contractual Term (Yrs.)

Earnings Per Share [Abstract]
Earnings Per Share	Earnings Per Share Basic earnings per share excludes dilution and is computed by dividing net income (loss) applicable to common shares by the weighted average number of common shares outstanding for the period. Diluted earnings per share reflects the potential impact of contingently issuable shares. The Company uses the treasury stock method as described by ASC 260 - Earnings Per Share for each dilutive instrument when computing diluted earnings per share. The following shows the weighted average number of shares used in computing earnings per share and the effect of weighted average number of shares dilutive potential common stock. Dilutive potential common stock has no effect on income available to common shareholders. Three Months Ended June 30, Six Months Ended June 30, 2024 2023 2024 2023 Net income (loss) applicable to common shares (in thousands) $ (17,144) $ 6,034 $ (11,932) $ 13,558 Weighted average number of shares 12,174,169 7,428,079 9,803,684 7,427,363 Options effect of dilutive shares — 86,876 — 82,468 Weighted average dilutive shares 12,174,169 7,514,955 9,803,684 7,509,831 Basic earnings (loss) per common share $ (1.41) $ 0.81 $ (1.22) $ 1.82 Diluted earnings (loss) per common share (1.41) 0.80 (1.22) 1.80 For the three months ended June 30, 2024, and the six months ended June 30, 2024, the options effect of dilutive shares is anti-dilutive and not considered in calculating diluted EPS. Stock awards equivalent to 323,902 and zero shares of common stock were not considered in computing diluted earnings per common share for the three months ended June 30, 2024, and June 30, 2023, respectively, because they are antidilutive. Stock awards equivalent to 329,572 and zero shares of common stock are not considered in computing diluted earnings per share for the six months ended June 30, 2024, and June 30, 2023, respectively, because they are antidilutive.

Business Combination, Asset Acquisition, and Joint Venture Formation [Abstract]
Business Combination	Business Combination Effective on May 3, 2024, Burke & Herbert completed the Merger with Summit, pursuant to the Merger Agreement. In the Merger, holders of Summit common stock outstanding at the effective time of the Merger received 0.5043 shares of Burke & Herbert common stock for each share of Summit common stock they owned, subject to the payment of cash in lieu of fractional shares. The total aggregate consideration payable in the Merger was approximately 7,405,772 shares of Burke & Herbert common stock. Additionally, each share of Summit’s 6.0% Fixed Rate Non-Cumulative Perpetual Preferred Stock, Series 2021 issued and outstanding was converted into the right to receive a share of Burke & Herbert Series 2021 Preferred Stock. Summit’s results of operations from May 3, 2024 were included in the Company’s results beginning with reporting as of June 30, 2024. Net interest income and pre-tax net income for Summit were estimated to be $25.3 million and $27.5 million, respectively, since the date of the acquisition through June 30, 2024 and are included in the Company’s Consolidated Statement of Income. Merger-related costs of $24.4 million are included in non-interest expense in the Company’s income statement for the six months ended, June 30, 2024. A portion of these Merger-related costs are captured in the line item Other Operating Non-Interest Expense on the consolidated Income Statement with further description in Note 13 - Other O perating Expense . An additional $14.9 million is captured in line items for Salaries and Wages, Pensions and Other Employee Benefits, Occupancy, and Equipment Rentals, depreciation and maintenance. These costs captured in those line items represent change-in-control payments, acceleration of benefit due to the change-in-control, software breakage, and other lease breakage fees. The fair value of the common shares issued as part of the consideration paid for Summit was determined in the basis of the closing price of the Company’s common shares on the date of completion of the merger. We accounted for the Merger using the acquisition method of accounting in accordance with ASC 805, Business Combinations and accordingly, the assets and liabilities of Summit were recorded at their respective fair values on the date of completion of the merger. The fair values of assets and liabilities are preliminary and subject to refinement for up to one year after the acquisition date as additional information relative to the acquisition date fair values becomes available. We recognized preliminary goodwill of $32.8 million in connection with the acquisition, which is not amortized for financial reporting purposes, but is subject to annual impairment testing. The goodwill arising from the transaction is not deductible for tax purposes and consisted largely of synergies and the cost savings resulting from the combining of the operations of the companies. The core deposit intangible represents the value of long-term deposit relationships acquired in this transaction and will be amortized over an estimated weighted average life of 7 years using an accelerated method which approximates the estimated run-off of the acquired deposits. The fair value of $68.8 million of intangible assets related to core deposits is subject to change pending the receipt of the final valuation. The fair value of purchased financial assets with credit deterioration was $380.8 million on the date of the acquisition. The gross contractual amounts receivable relating to the purchased financial assets with credit deterioration was $442.3 million. The Company estimates, on the date of the acquisition, that $23.9 million of the contractual cash flows specific to the purchased financial assets with credit deterioration will not be collected. The following table details the total consideration paid for Summit on May 3, 2024, the fair values of the assets acquired and liabilities assumed and the resulting preliminary goodwill at the acquisition date.

Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The accompanying consolidated financial statements include Burke & Herbert Financial Services Corp. and its wholly owned subsidiary Burke & Herbert Bank & Trust Company and have been prepared in accordance with generally accepted accounting principles in the United States of America (“GAAP”) for interim financial reporting and with applicable quarterly reporting regulations of the U.S. Securities and Exchange Commission (“SEC”). The accounting and reporting policies of the Company conform to GAAP and reflect practices of the banking industry. They do not include all of the information and notes required by GAAP for complete financial statements. As such, these unaudited financial statements should be read in conjunction with the consolidated financial statements and notes thereto as of and for the year ending December 31, 2023, included in the Company’s Annual Report on Form 10-K filed with the SEC on March 22, 2024 and as amended on April 12, 2024. The consolidated financial statements include the accounts of the Company and the Bank (as its wholly-owned subsidiary). All significant intercompany accounts and transactions between the Company and the Bank have been eliminated. In preparing 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 sheet and reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. In the opinion of management, all adjustments, consisting only of normal recurring adjustments, which are necessary for a fair presentation of the results of operations in these financial statements, have been made. The results of operations for the three and six months ended June 30, 2024, are not necessarily indicative of the results to be expected for any other interim period or for the full year. All December 31, 2023 amounts and disclosures included in this quarterly report were derived from the Company’s audited consolidated financial statements. Certain items in the prior period have been reclassified to conform to the current presentation. These reclassifications had no effect on prior year net income or on shareholders’ equity. Purchased Credit Deteriorated (PCD) Loans The Company has purchased loans, some of which have experienced more than insignificant credit deterioration since origination. PCD loans are loans on nonaccrual status, are greater than 60 days past due at any time since loan origination or have a risk rating of special mention, substandard, doubtful, or loss. PCD loans are recorded at the amount paid. An allowance for credit losses is determined using the same methodology as other loans held for investment. The initial allowance for credit losses determined on a collective basis is allocated to individual loans. The sum of the loan’s purchase price and allowance for credit losses becomes its initial amortized cost basis. The difference between the initial amortized cost basis and the par value of the loan is a noncredit discount or premium, which is amortized into interest income over the life of the loan. Subsequent changes to the allowance for credit losses are recorded through credit loss expense. Goodwill and Other Intangible Assets Goodwill arises from business combinations and is determined as the excess of the fair value of the consideration transferred, plus the fair value of any noncontrolling interests in the acquiree, over the fair value of the net assets acquired and liabilities assumed as of the acquisition date. Goodwill and intangible assets acquired in a business combination and determined to have an indefinite useful life are not amortized, but tested for impairment at least annually or more frequently if events and circumstances exist that indicate that an impairment test should be performed. The Company has selected September 30 as the date to perform the annual impairment test. Intangible assets with finite useful lives are amortized over their estimated useful lives to their estimated residual values. Amortized intangibles must be reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of the long-lived asset (group) might not be recoverable. An impairment loss related to intangible assets with finite useful lives is recognized if the carrying amount of the intangible asset is not recoverable and its carrying amount exceeds its fair value. After the impairment loss is recognized, the adjusted carrying amount of the intangible asset shall be its new accounting basis. Goodwill is the only intangible asset with an indefinite life on our balance sheet. Other intangible assets consists of core deposit intangible assets arising from whole bank and branch acquisitions and is amortized using an accelerated method over their estimated useful lives of seven years.

Recently adopted accounting standards and Pending adoption of new accounting standards	Recently adopted accounting standards In March 2023, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Updated (“ASU”) 2023-02, Investments—Equity Method and Joint Ventures (Topic 323): Accounting for Investments in Tax Credit Structures Using the Proportional Amortization Method . These amendments allow reporting entities to elect to account for qualifying tax equity investments using the proportional amortization method, regardless of the program giving rise to the related income tax credits. The ASU was effective for us January 1, 2024, and did not have a material impact on our consolidated financial statements. In June 2022, the FASB issued ASU 2022-03, Fair Value Measurement (Topic 820): Fair Value Measurement of Equity Securities Subject to Contractual Sale Restrictions . ASU 2022-03 clarifies that a contractual restriction on the sale of an equity security is not considered part of the unit of account of the equity security and, therefore, is not considered in measuring fair value. The ASU was effective for us January 1, 2024, and did not have a material impact on our consolidated financial statements. Pending adoption of new accounting standards In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740) : Improvements to Income Tax Disclosures . The amendments in this ASU require an entity to disclose specific categories in the rate reconciliation and provide additional information for reconciling items that meet a quantitative threshold, which is greater than five percent of the amount computed by multiplying pretax income by the entity’s applicable statutory rate, on an annual basis. Additionally, the amendments in this ASU require an entity to disclose the amount of income taxes paid (net of refunds received) disaggregated by federal, state, and foreign taxes and the amount of income taxes paid (net of refunds received) disaggregated by individual jurisdictions that are equal to or greater than five percent of total income taxes paid (net of refunds received). Lastly, the amendments in this ASU require an entity to disclose income (or loss) from continuing operations before income tax expense (or benefit) disaggregated between domestic and foreign and income tax expense (or benefit) from continuing operations disaggregated by federal, state, and foreign. This ASU is effective for annual periods beginning after December 15, 2024. Early adoption is permitted. The amendments should be applied on a prospective basis; however, retrospective application is permitted. We do not expect the adoption of ASU 2023-09 to have a material impact on our consolidated financial statements. In October 2023, the FASB issued ASU 2023-06, Disclosure Improvements: Codification Amendments in Response to the SEC’s Disclosure Update and Simplification Initiative . This ASU incorporates certain SEC disclosure requirements into the FASB Accounting Standards Codification. The amendments in the ASU are expected to clarify or improve disclosure and presentation requirements of a variety of Codification Topics, allow users to more easily compare entities subject to the SEC’s existing disclosures with those entities that were not previously subject to the requirements, and align the requirements in the Codification with the SEC’s regulations. For entities subject to the SEC’s existing disclosure requirements and for entities required to file or furnish financial statements with or to the SEC in preparation for the sale of or for purposes of issuing securities that are not subject to contractual restrictions on transfer, the effective date for each amendment will be the date on which the SEC removes that related disclosure from its rules. For all other entities, the amendments will be effective two years later. However, if by June 30, 2027, the SEC has not removed the related disclosure from its regulations, the amendments will be removed from the Codification and not become effective for any entity. We do not expect the adoption of ASU 2023-06 to have a material impact on our consolidated financial statements.
Fair Value Measurements	Fair value is the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. There are three levels of inputs that may be used to measure fair values: Level 1 – Quoted prices (unadjusted) for identical assets or liabilities in active markets that the entity has the ability to access as of the measurement date. Level 2 – Significant other observable inputs other than Level 1 prices such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data. Level 3 – Significant unobservable inputs that reflect our own assumptions that market participants would use in pricing an asset or liability. In instances in which multiple levels of inputs are used to measure fair value, hierarchy classification is based on the lowest level input that is significant to the fair value measurement in its entirety. The Company’s assessment of the significance of a particular input to the fair value measurement in its entirety requires judgment and considers factors specific to the asset or liability. The Company used the following methods and significant assumptions to estimate fair value: Investment securities The fair values for investment securities are determined by quoted market prices, if available (Level 1). For securities where quoted prices are not available, fair values are calculated based on market prices of similar securities (Level 2), using matrix pricing. Matrix pricing is a mathematical technique commonly used to price debt securities without relying exclusively on quoted prices for the specific securities but rather by relying on securities’ relationship to other benchmark quoted securities (Level 2 inputs). For securities where quoted prices or market prices of similar securities are not available, fair values are calculated using discounted cash flows or other market indicators (Level 3). Equity Investments Equity investments are recorded at fair value on a recurring basis, with changes in fair value reported in net income. Through the Merger, at June 30, 2024, we acquired an investment in an S&P 500 index mutual fund that is actively traded on an exchange, and we classify it as Level 1. Through the Merger, we acquired perpetual preferred stock of a bank holding company issued in October 2022 in a private offering. The perpetual preferred stock does not trade on an exchange or in an active over-the-counter market; therefore, we estimate its fair value using the present value of its future cash flows using observed discount rates of similar publicly-traded securities, adjusted for a liquidity premium. We classify the perpetual preferred stock as Level 2. Equity securities without readily determinable fair values are carried at cost, minus impairment, if any, plus or minus changes resulting from observable price changes in orderly transactions for an identical or similar investment. Such equity securities are included in Equity Investments on the accompanying consolidated balance sheets. Derivatives The fair values of derivatives are based on valuation models using observable market data as of the measurement date (Level 2). The Company has contracted with a third-party vendor to provide valuations for interest rate swaps using standard swap valuation techniques. The Company has considered counterparty credit risk in the valuation of its interest rate swap assets and has considered its own credit risk in the valuation of its interest rate swap liabilities. The Company recognizes interest rate lock commitments at fair value. Fair value of interest rate lock commitments is based on the price of underlying loans obtained from an investor for loans that will be delivered on a best effort basis (Level 2). Loans held-for-sale, at fair value The fair value of loans held-for-sale is determined using quoted prices for similar assets, adjusted for specific attributes of that loan (Level 2). These loans currently consist of one-to-four family residential loans originated for sale in the secondary market. Collateral dependent loans Loans for which the borrower is experiencing financial difficulty and repayment is dependent upon the operation or sale of collateral, are considered collateral dependent. For collateral-dependent loans, the fair value is measured based on the value of the collateral securing the loans, less estimated costs of disposal. Collateral may be in the form of real estate or business assets, including equipment, inventory, and accounts receivable. The vast majority of the collateral underlying collateral dependent loans is real estate, the fair value of which is measured through an appraisal. The appraisals of the collateral supporting collateral dependent loans may utilize a single valuation approach or a combination of approaches, including comparable sales and the income approach. Any fair value adjustments are recorded in the period incurred as provision for credit losses on the Consolidated Statements of Income. Non-real estate collateral may be valued using an appraisal, net book value per the borrower’s financial statements, or aging reports, adjusted or discounted based on management’s historical knowledge, changes in market conditions from the time of the valuation, and management’s expertise and knowledge of the client and client’s business. Other real estate owned Assets acquired through foreclosure or other proceedings are initially recorded at fair value less costs to sell when acquired, establishing a new cost basis. The fair value of foreclosed properties is determined on a nonrecurring basis generally utilizing current appraisals performed by an independent, licensed appraiser applying an income or market value approach using observable market data. Updated appraisals of foreclosed properties are generally obtained if the existing appraisal is more than 18 months old or more frequently if there is a known deterioration in value. However, if a current appraisal is not available, the original appraised value is discounted, as appropriate, to compensate for the estimated depreciation in the value of the real estate since the date of its original appraisal. Such discounts are generally estimated based upon management’s knowledge of sales of similar property within the applicable market area and its knowledge of other real estate market-related data as well as general economic trends. Upon foreclosure, any fair value adjustment is charged against the allowance for credit losses on loans. Subsequent fair value adjustments are recorded in the period incurred and included in other noninterest expense in the consolidated statements of income.
