Item 5.02 - Departure of Directors or Certain Officers; Election of Directors; Appointment of Certain Officers; Compensatory Arrangements of Certain Officers

Appointment of LNKB Continuing Directors

As previously announced, on December 18, 2025, Burke & Herbert Financial Services Corp. ("Burke & Herbert") and LINKBANCORP, Inc. ("LNKB") entered into an Agreement and Plan of Merger (the "Merger Agreement"), dated as of December 18, 2025, pursuant to which, upon the terms and subject to the conditions set forth therein, LNKB will merge with and into Burke & Herbert, with Burke & Herbert continuing as the surviving corporation (the "Merger"). The Merger Agreement further provides that immediately following the Merger, LINKBANK, the wholly owned Pennsylvania-chartered commercial bank subsidiary of LNKB ("Link"), will merge with and into Burke & Herbert Bank & Trust Company, a Virginia-chartered bank and a wholly owned subsidiary of Burke & Herbert ("B&H Bank"), with B&H Bank as the surviving bank (the "Subsidiary Merger" and, together with the Merger, the "Transaction").

The Merger Agreement requires Burke & Herbert to take all actions necessary immediately prior to the effective time of the Merger (the "Effective Time"), to cause the number of directors that will comprise the full board of directors of the surviving corporation at the Effective Time to be increased by two members (or less to the extent there are vacant seats), and appoint to the board of directors of the surviving corporation two members of the board of directors of LNKB, each of whom would qualify as an "independent director" pursuant to the listing standards of the Nasdaq Stock Market LLC as mutually agreed by Burke & Herbert and LNKB (such directors, the "LNKB Continuing Directors").

On March 9, 2026, the Board of Directors of Burke & Herbert (the "BHRB Board") appointed current LNKB directors Diane Poillon and Kristen Snyder to the board of the surviving corporation as the LNKB Continuing Directors, subject to and effective upon the completion of the Merger. Both Ms. Poillon and Ms. Snyder are to be appointed to the Audit Committee of the BHRB Board, effective immediately after their appointment to the BHRB Board becomes effective. The BHRB Board intends to amend BHRB's Amended and Restated Bylaws prior to completion of the merger to the extent necessary to increase the size of the BHRB Board to accommodate the LNKB Continuing Directors.

Ms. Poillon, age 56, has served on the LNKB Board of Directors (the "LNKB Board") since 2019. Ms. Poillon is President and Chief Executive Officer of Willow Valley Associates. She has 30 years of experience in the hospitality and real estate business at Willow Valley in roles including Chief Operating Officer, Executive Vice President of Focus Service Hotels, Director of Learning and Development, Director of Safety and Manager of Family Restaurant. Ms. Poillon is an active community leader in Central Pennsylvania, including positions on the boards of the Lancaster General Health Foundation, Lancaster Chamber of Commerce & Industry and Water Street Mission.

Ms. Snyder, age 41, has served on the LNKB Board since the consummation of LNKB's merger with GNB Financial Services, Inc. ("GNB") in September 2021, and prior to that, was a director of GNB and its wholly owned subsidiary, Gratz Bank since 2018. Ms. Snyder is a principal of Koppy's Propane, Inc., overseeing Operations, Finance, Safety and Human Resources. Prior to that, she served as Senior Analyst for JPMorgan Chase & Co. from 2007 to 2010.

Each of the LNKB Continuing Directors will receive the same compensation as currently paid to other members of the boards of directors of Burke & Herbert and B&H Bank. A description of Burke & Herbert's standard non-employee director compensation arrangement is contained under the heading "Director Compensation" in Burke & Herbert's Definitive Proxy Statement on Schedule 14A filed with the Securities and Exchange Commission ("SEC") on March 31, 2025 (the "Definitive Proxy Statement").

Other than as described above and in Burke & Herbert's Registration Statement on Form S-4 (File No. 333-292956), initially filed with the SEC on January 26, 2026, and as amended and declared effective by the SEC on January 30, 2026 (the "Registration Statement"), there are no arrangements or understandings between the LNKB Continuing Directors and any other person pursuant to which any of the LNKB Continuing Directors have been designated to serve on the boards of directors of either Burke & Herbert or B&H Bank. Additionally, there have been no transactions or are there any proposed transactions between Burke & Herbert and any of the LNKB Continuing Directors that would require disclosure pursuant to Item 404(a) of Regulation S-K.

Each of Mses. Poillon and Snyder has executed a consent in accordance with Rule 438 promulgated under the Securities Act of 1933, as amended. Such consents are filed as Exhibits 99.1 and 99.2 to this Current Report on Form 8-K and are incorporated by reference into and as exhibits to the Registration Statement.

Departure of Directors

On March 9, 2026, Jill S. Upson notified the Chair of the BHRB Board of her decision to not stand for re-election as a director at the Company's 2026 annual meeting of shareholders. Ms. Upson will continue to serve as a director and on the committees of which she is a member until her term expires at the 2026 annual meeting of shareholders. Ms. Upson's decision to not stand for re-election is not a result of any disagreement with the Company, management or the BHRB Board on any matter relating to the Company's operations, policies or practices.

In addition, it is expected that directors Oscar M. Bean and Gary L. Hinkle will not be nominated for re-election at the Company's 2026 annual meeting of shareholders since they have surpassed the age limit for service on the BHRB Board as set forth in the Company's Amended and Restated Bylaws.

The Company thanks each of Ms. Upson and Messrs. Bean and Hinkle for their service as a member of the BHRB Board.

Forward-Looking Statements

This Current Report on Form 8-K includes "forward-looking statements" within the meaning of the Private Securities Litigation Reform Act of 1995, Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended, including with respect to (or based on) the beliefs, goals, intentions, and expectations of Burke & Herbert regarding the proposed Merger and the Merger Agreement, the expected appointment of the LNKB Continuing Directors, and other statements that are not historical facts. Forward-looking statements are typically identified by such words as "believe," "expect," "anticipate," "intend," "outlook," "estimate," "forecast," "project," "will," "should," and other similar words and expressions, and are subject to numerous assumptions, risks, and uncertainties, which change over time. Forward-looking statements include, without limitation, those relating to the terms, timing and closing of the proposed Merger.

Additionally, forward-looking statements speak only as of the date they are made; Burke & Herbert does not assume any duty, and do not undertake, to update such forward-looking statements, whether written or oral, that may be made from time to time, whether as a result of new information, future events, or otherwise. 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 as a result of a variety of factors, many of which are beyond the control of Burke & Herbert. Such statements are based upon the current beliefs and expectations of the management of Burke & Herbert and are subject to significant risks and uncertainties outside of the control of the parties. Caution should be exercised against placing undue reliance on forward-looking statements. The factors that could cause actual results to differ materially include the following: the occurrence of any event, change or other circumstances that could give rise to the right of one or both of the parties to terminate the definitive Merger Agreement; the outcome of any legal proceedings that may be instituted against Burke & Herbert or LNKB; the possibility that the proposed Merger will not close when expected or at all because required regulatory, shareholder or other approvals are not received or other conditions to the closing are not satisfied on a timely basis or at all, or are obtained subject to conditions that are not anticipated (and the risk that required regulatory approvals may result in the imposition of conditions that could adversely affect the combined company or the

expected benefits of the proposed Merger); and other factors that may affect future results of Burke & Herbert; and the other factors discussed in the "Risk Factors" section of Burke & Herbert's Annual Report on Form 10-K for the year ended December 31, 2025.
