&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;2 SAFE HARBOR STATEMENT Statements in this presentation which are not historical are "forward-looking statements" within the meaning of Section 27A of the Securities Act of 1933, as amended, Section 21E of the Securities Exchange Act of 1934, as amended, and the Private Securities Litigation Reform Act of 1995. These forward-looking statements may include discussions of the strategic plans and objectives or anticipated future performance and events of Peoples Bancorp Inc. ("Peoples"). The information contained in this presentation should be read in conjunction with Peoples' Annual Report on Form 10-K for the fiscal year ended December 31, 2025 (the "2025 Form 10-K"), and the Quarterly Report on Form 10-Q for the quarter ended March 31, 2026, each of which is available on the Securities and Exchange Commission's ("SEC")'s website (sec.gov) or at Peoples' website (peoplesbancorp.com). Investors are cautioned that forward-looking statements, which are not historical fact, involve risks and uncertainties, including those detailed in the 2025 Form 10-K under the section, "Risk Factors" in Part I, Item 1A. As such, actual results could differ materially from those contemplated by forward- looking statements made in this presentation. Management believes that the expectations in these forward-looking statements are based upon reasonable assumptions within the bounds of management's knowledge of Peoples' business and operations. Peoples disclaims any responsibility to update these forward-looking statements to reflect events or circumstances after the date of this presentation. IMPORTANT INFORMATION FOR INVESTORS AND SHAREHOLDERS This presentation does not constitute an offer to sell or the solicitation of an offer to buy securities of Peoples. Peoples will file a registration statement on Form S-4 and other documents regarding the proposed transaction referenced in this presentation with the SEC to register the shares of Peoples common stock to be issued to the shareholders of Citizens National Corporation ("Citizens"). The registration statement will include a proxy statement of Citizens that also constitutes a prospectus of Peoples, which, when finalized, will be sent to the shareholders of Citizens seeking their approval of the merger-related proposals. Investors and security holders are urged to read the proxy statement/prospectus and any other relevant documents to be filed with the SEC in connection with the proposed transaction because they will contain important information about Peoples, Citizens and the proposed transaction. Investors and security holders may obtain a free copy of these documents (when available) through the website maintained by the SEC (sec.gov) or at Peoples (peoplesbancorp. com). These documents may also be obtained, without charge, by directing a request to Peoples Bancorp Inc., 138 Putnam Street, P.O. Box 738, Marietta, Ohio 45750, Attn.: Investor Relations. Peoples and Citizens and certain of their directors and executive officers may be deemed to be participants in the solicitation of proxies from the shareholders of Citizens in connection with the proposed merger. Information about the directors and executive officers of Peoples is set forth in the proxy statement for Peoples' 2026 annual meeting of shareholders, as filed with the SEC on Schedule 14A on March 6, 2026. Information about the directors and executive officers of Citizens and their ownership of Citizens common stock, as well as additional information regarding the participants in the proxy solicitation and a description of their direct and indirect interests, by securities holdings or otherwise, will be included in the proxy statement/prospectus and other relevant documents regarding the proposed transaction to be filed with the SEC when they become available.

NASDAQ: PEBO APPENDIX NON-US GAAP MEASURES 36 (a) Tax effect is calculated using a 21% federal statutory tax rate for all periods represented. RETURN ON AVERAGE TANGIBLE STOCKHOLDERS' EQUITY The return on average tangible stockholders' equity ratio is a key financial measure used to monitor performance. It is calculated as net income (less after-tax impact of amortization of other intangible assets) divided by average tangible stockholders' equity. This measure is non-US GAAP since that excludes the after-tax impact of amortization of other intangible assets from earnings and the impact of goodwill and other intangible assets acquired through acquisitions on total stockholders' equity.
