1 September 2026 Fixed Income Investor Presentation

2 Forward - Looking Statements This presentation contains statements that Burke & Herbert Financial Services Corp . (the “Company”) believes are, or may be considered to be, “forward - looking statements,” within the meaning of the Private Securities Litigation Reform Act of 1995 , Section 27 A of the Securities Act of 1933 , as amended, and Section 21 E of the Securities Exchange Act of 1934 , as amended, with respect to the beliefs, goals, intentions, and expectations of the Company regarding matters such as the Company’s merger with LINKBANCORP, Inc . (“LNKB”) and the expected cost savings, synergies, returns, and other anticipated benefits from the integration of LNKB ; revenues, earnings, earnings per share, loan production, asset quality, and capital levels, among other matters ; estimates of the future costs and benefits of the actions the Company may take ; assessments of expected losses on loans ; assessments of interest rate and other market risks ; ability to achieve the Company’s financial and other strategic goals ; and other statements that are not historical facts . Forward - looking statements are neither historical facts nor assurances of future performance . Instead, they are based on current beliefs, expectations, or assumptions regarding the future of the business, future plans and strategies, operational results, and other future conditions of the Company . All statements other than statements of historical fact included in this presentation regarding the prospects of the Company’s industry or the Company’s prospects, plans, financial position, or business strategy may constitute forward - looking statements . In addition, forward - looking statements generally can be identified by the use of forward - looking words such as “plans,” “expects” or “does not expect,” “is expected,” “look forward to,” “budget,” “scheduled,” “estimates,” “forecasts,” “will continue,” “intends,” “the intent of,” “have the potential,” “anticipates,” “does not anticipate,” “believes,” “should,” “should not,” or variations of such words and phrases that indicate that certain actions, events, or results “may,” “could,” “would,” “might,” or “will,” “be taken,” “occur,” or “be achieved,” or the negative of these terms or variations of them or similar terms . Additionally, forward – looking statements speak only as of the date they are made ; the Company does not assume any duty, does not undertake, and specifically disclaims any obligation to update such forward – looking statements, whether written or oral, that may be made from time to time, whether because of new information, future events, or otherwise, except as required by law . Furthermore, because forward – looking statements are subject to assumptions and uncertainties, actual results or future events could differ, possibly materially, from those indicated in or implied by such forward - looking statements because of a variety of factors, many of which are beyond the control of the Company . Further, factors identified herein are not necessarily all of the factors that could cause the Company’s actual results, performance or achievements to differ materially from those expressed in or implied by any of the forward - looking statements . Other factors, including unknown or unpredictable factors, also could harm the Company . Accordingly, you should consider all of these risks, uncertainties and other factors carefully in evaluating all such forward - looking statements made by the Company and not place undue reliance on forward - looking statements . The risks and uncertainties that could cause actual results to differ from those described in the forward - looking statements include, but are not limited to, the following : the possibility that the anticipated benefits of the merger with LNKB (the “LNKB Merger”) will not be realized when expected or at all, including as a result of the impact of, or problems arising from (if any), the integration of the two companies or as a result of the strength of the economy and competitive factors in the areas where the Company does business ; costs or difficulties associated with newly developed or acquired operations ; the possibility that the Company may be unable to achieve expected synergies and operating efficiencies of the LNKB Merger within the expected timeframes or at all and to successfully integrate LNKB’s operations and those of the Company ; that the integration of LNKB may be more difficult, time - consuming or costly than expected ; revenues following the LNKB Merger may be lower than expected ; the Company’s success in executing its business plans and strategies and managing the risks involved in the foregoing ; risks related to the potential impact of global macroeconomic conditions and changes in general economic, political and market factors on the integration of LNKB or the Company’s operations generally (either nationally or locally in the areas in which the Company conducts, or will conduct, business), including inflation, changes in interest rates, market volatility and monetary fluctuations, and changes in federal government policies and practices, including the impact with respect to spending on industries concentrated in the Company’s market area, as well as the impact from tariffs on the markets the Company serves ; increased competition ; changes in consumer confidence and demand for financial services, including changes in consumer borrowing, repayment, investment, and deposit practices ; changes in asset quality and credit risk ; our ability to control costs and expenses ; adverse developments in borrower industries or declines in real estate values ; changes in and compliance with federal and state laws and regulations that pertain to our business and capital levels ; our ability to raise capital as needed ; the impact, extent and timing of technological changes ; the effects of any cybersecurity breaches or events ; the development and use of artificial intelligence (“AI”) in business processes, services, and products, including emerging external focus among regulators and other officials related to risks in connection with the development and use of AI ; the potential adverse effects of unusual and infrequently occurring events, such as weather - related disasters, terrorist acts, geopolitical conflicts and tensions, or public health events (such as pandemics), and of governmental and societal responses thereto ; and the other factors discussed in the “Risk Factors” and “Management's Discussion and Analysis of Financial Condition and Results of Operations” section of the Company's Annual Report on Form 10 – K for the year ended December 31 , 2025 .

4 Non - GAAP Financial Measures This presentation contains certain financial measures determined by methods other than in accordance with accounting principles generally accepted in the United States of America (“GAAP”) . Management uses these non - GAAP financial measures to assess the performance of the Company’s core business and the strength of its capital position . Management believes that these non - GAAP financial measures provide meaningful additional information about the Company to assist investors in evaluating operating results, financial strength, and capitalization . The non - GAAP financial measures should be considered as additional views of the way the Company’s financial measures are affected by significant charges for credit costs and other factors . These non - GAAP financial measures should not be considered as a substitute for operating results determined in accordance with GAAP and may not be comparable to other similarly titled measures of other companies . For a reconciliation of the non - GAAP financial measures used herein to the most directly comparable financial measures prepared in accordance with GAAP, see the appendix to this presentation .

As such, these tax - exempt instruments typically yield lower returns than taxable investments . To provide more meaningful comparisons of net interest income, we use net interest income on a fully taxable - equivalent (FTE) basis by increasing the interest income earned on tax - exempt assets to make it fully equivalent to interest income earned on taxable investments . FTE net interest income is calculated by adding the tax benefit on certain financial interest earning assets, whose interest is tax - exempt, to total interest income then subtracting total interest expense . Management believes FTE net interest income is a standard practice in the banking industry, and when net interest income is adjusted on an FTE basis, yields on taxable, nontaxable, and partially taxable assets are comparable ; however, the adjustment to an FTE basis has no impact on net income and this adjustment is not permitted under GAAP . FTE net interest income is only used for calculating FTE net interest margin, which is calculated by annualizing FTE net interest income and then dividing by the average earning assets .

41 Appendix: Notes on Non - GAAP Financial Measures Return and Adjusted Return on Average Tangible Common Equity and Average Assets : In management’s view, adjusted return on average common equity, return on average tangible common equity, adjusted return on average tangible common equity, and adjusted return on average assets are performance metrics that may be meaningful to the Company, as well as analysts and investors, in evaluating the Company’s profitability and efficiency in deploying capital and assets and in facilitating comparisons with peers . These non - GAAP financial measures provide additional insight into the Company’s underlying operating performance by focusing on returns generated from common equity, tangible common equity, and total assets, as applicable . The adjusted measures exclude the after - tax effect of one - time merger - related expenses, which management believes enhances period - to - period comparability and provides a more representative view of the Company’s ongoing earnings performance . Return on average tangible common equity measures further isolate performance attributable to tangible capital by excluding the impact of intangible assets, while return on average assets reflects the Company’s effectiveness in generating earnings from its overall asset base . Management believes these measures, when considered together and alongside GAAP results, provide useful supplemental information for assessing profitability, capital efficiency, and operating trends .
