Opinions on the Financial Statements and Internal Control over Financial Reporting

We have audited the accompanying consolidated balance sheets of Burke & Herbert Financial Services Corp. (the "Company") as of December 31, 2025 and 2024, the related consolidated statements of income, comprehensive income, changes in shareholders’ equity, and cash flows for each of the years in the three-year period ended December 31, 2025, and the related notes (collectively referred to as the "financial statements"). We also have audited the Company’s internal control over financial reporting as of December 31, 2025, based on criteria established in Internal Control – Integrated Framework: (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO).

In our opinion, the financial statements referred to above present fairly, in all material respects, the financial position of the Company as of December 31, 2025 and 2024, and the results of its operations and its cash flows for each of the years in the three-year period ended December 31, 2025 in conformity with accounting principles generally accepted in the United States of America. Also in our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2025, based on criteria established in Internal Control – Integrated Framework: (2013) issued by COSO.

Basis for Opinions

The Company’s management is responsible for these financial statements, for maintaining effective internal control over financial reporting, and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management’s Annual Report on Internal Control Over Financial Reporting. Our responsibility is to express an opinion on the Company’s financial statements and an opinion on the Company’s internal control over financial reporting based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) ("PCAOB") and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud, and whether effective internal control over financial reporting was maintained in all material respects.

Our audits of the financial statements included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audits also included performing such other procedures as we considered necessary in the circumstances. We believe that our audits provide a reasonable basis for our opinions.

Definition and Limitations of Internal Control Over Financial Reporting

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Critical Audit Matter

The critical audit matter communicated below is a matter arising from the current period audit of the financial statements that was communicated or required to be communicated to the audit committee and that: (1) relates to accounts or disclosures that are material to the financial statements and (2) involved our especially challenging, subjective, or complex judgments. The communication of the critical audit matter does not alter in any way our opinion on the financial statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing a separate opinion on the critical audit matter or on the accounts or disclosures to which it relates.

Allowance for credit losses - loans

As more fully described in Notes 1 and 4 of the financial statements, the allowance for credit losses reflects expected credit losses in the loan portfolio. The Company is using the remaining useful life or weighted average remaining maturity methodology to calculate the quantitative component. The quantitative component includes reasonable and supportable forecasts of loss rates over a two-year period. In order to generate reasonable and supportable forecasts, the allowance for credit loss calculation utilizes macroeconomic variable loss drivers, which may include aggregate macroeconomic indicators pertaining to such items as equity market conditions or interest rates, as well as other variables that are portfolio-specific. A straight-line reversion technique is used for the following four quarters which then reverts to historical average loss rates. 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. Management may consider an additional or reduced reserve as warranted through the qualitative risk factors component based on the current and expected conditions.

Auditing the allowance for credit losses was especially challenging given the significant volume of data applied in the calculations. The audit of the allowance for credit loss calculation involved significant audit effort, including the involvement of experienced audit personnel and our internal specialists, and a high degree of auditor judgment in applying the audit procedures.

The primary procedures we performed to address the critical audit matter included:

Testing the design and operating effectiveness of internal controls over management’s allowance for credit loss calculation, including controls over the:

•Completeness and accuracy of data, including the input, transfer, aggregation, and processing of information within the allowance for credit loss calculation.

•Mathematical accuracy of the allowance for credit loss calculation.

•Reasonableness of significant assumptions and judgments applied within the allowance for credit loss calculation.

Substantively testing management’s process to estimate the allowance for credit loss calculation, including:

•Testing the completeness and accuracy of the underlying internal data utilized to prepare the calculation.

•Evaluating the relevance and reliability of the underlying external data utilized to prepare the calculation.

•Testing the mathematical accuracy, including the transfer, aggregation, and processing of data and the application of assumptions, of the allowance for credit loss calculation.

•Evaluating the reasonableness of the significant judgments and assumptions utilized within the allowance for credit loss calculation.
