**Notice of Annual Meeting of Shareholders**

**Peoples Bancorp Inc.**

|:---|:---|:---|:---|
| &nbsp;&nbsp;**Date**<br>Thursday,<br>April 23, 2026 | &nbsp;&nbsp;**Time**<br>10:00 a.m.<br>(Eastern Daylight Saving Time) | &nbsp;&nbsp;**Place**<br>Via Live Webcast at<br>www.proxydocs.com/pebo | &nbsp;&nbsp;**Record Date**<br>February 23, 2026 |

The Annual Meeting of Shareholders (the "Annual Meeting") of Peoples Bancorp Inc. ("Peoples") will be held for the following purposes:

1. To elect eleven directors to the Peoples Board of Directors, each to serve for a term of one year expiring at the 2027 Annual Meeting of Shareholders.

2. To consider and vote upon a proposal to approve a non-binding advisory resolution to approve the compensation of Peoples' named executive officers as disclosed in the accompanying Proxy Statement for the Annual Meeting.

3. To consider and vote upon a proposal to ratify the appointment of Ernst & Young LLP as Peoples' independent registered public accounting firm for the fiscal year ending December 31, 2026.

4. To transact any other business that properly comes before the Annual Meeting. As of the date of this Proxy Statement, Peoples' Board of Directors is not aware of any other business to come before the Annual Meeting.

If you were a holder of record of common shares of Peoples at the close of business on February 23, 2026, you will be entitled to vote at the Annual Meeting.

We have elected to take advantage of Securities and Exchange Commission ("SEC") rules that allow us to furnish proxy materials to certain shareholders over the internet. On or about the date of this Notice of Annual Meeting of Shareholders, we began mailing a notice of internet availability of proxy materials (the "Notice of Internet Availability") to shareholders of record at the close of business on February 23, 2026. The Notice of Internet Availability contains information on how to access the Notice of Annual Meeting of Shareholders, the Proxy Statement (which describes in detail each of the matters to be considered at the Annual Meeting), the form of proxy and Peoples' 2025 Annual Report to Shareholders over the internet, as well as instructions on how to request a paper copy of the proxy materials. At the same time, we provided shareholders of record with access to our online proxy materials and filed our proxy materials with the SEC. We believe furnishing proxy materials to our shareholders over the internet allows us to provide our shareholders with the information they need, while lowering the costs of delivery and reducing the environmental impact of the Annual Meeting. If you have received the Notice of Internet Availability, you will not receive a printed copy of the proxy materials unless you request it by following the instructions for requesting such proxy materials contained in the Notice of Internet Availability and summarized on the following page.

It is important that your common shares be represented at the Annual Meeting whether or not you are personally able to participate. Accordingly, after reading the accompanying Proxy Statement, please promptly submit your proxy by telephone, over the internet or by mail as described in the Proxy Statement.

**YOUR VOTE IS IMPORTANT**

**Your common shares may be voted by one of the following methods:**

![2026_2_Proxy Statement_internet telephone mail graphic.jpg](pebo-20260306_g3.jpg)

Submitting your proxy over the internet, by telephone or by mail does not deprive you of the right to participate in the Annual Meeting live via the internet and to vote your common shares online in the manner described in the accompanying Proxy Statement.

*To obtain instructions as to how to participate in the Annual Meeting virtually, please call Investor Relations at 740-374-6136.*

**Proxy Statement for the Annual Meeting of Shareholders**

**To Be Held on April 23, 2026**

**GENERAL INFORMATION**

This Proxy Statement is furnished in connection with the solicitation of proxies on behalf of the Board of Directors (the "Board") of Peoples Bancorp Inc. ("Peoples") for use at the Annual Meeting of Shareholders, to be held on Thursday, April 23, 2026, at 10:00 a.m., Eastern Daylight Saving Time (the "2026 Annual Meeting" or the "Annual Meeting"). This Proxy Statement summarizes the information that you will need in order to vote. The Annual Meeting will be held solely over the internet in a virtual-only format, which means that you will be able to participate in the Annual Meeting, vote, and submit your questions during the Annual Meeting via live webcast by visiting www.proxydocs.com/pebo. Because the Annual Meeting will be held in a virtual-only format, you will not be able to attend the Annual Meeting in person at a physical location.

**Mailing**

On or about March 13, 2026, we began mailing a notice of internet availability of proxy materials (the "Notice of Internet Availability") to all registered shareholders entitled to vote their common shares at the Annual Meeting. The Notice of Internet Availability contains instructions on how to access the Notice of Annual Meeting of Shareholders, this Proxy Statement, the form of proxy and Peoples' 2025 Annual Report to Shareholders, which includes the Annual Report of Peoples on Form 10-K for the fiscal year ended December 31, 2025 (the "2025 Annual Report"), over the internet.

**Copies of the 2025 Annual Report may be obtained, without charge, by sending a written request to: M. Ryan Kirkham, Corporate Secretary, Peoples Bancorp Inc., 138 Putnam Street, P.O. Box 738, Marietta, Ohio 45750-0738. A copy of the 2025 Annual Report can be obtained through the "SEC Filings – Annual Reports" section of the "Investor Relations" page of Peoples' website at www.peoplesbancorp.com and is also on file with the Securities and Exchange Commission (the "SEC") and available on the SEC's website at www.sec.gov.**

**SHAREHOLDER PROPOSALS FOR 2027 ANNUAL MEETING**

Proposals by shareholders intended to be presented at the 2027 Annual Meeting of Shareholders (the "2027 Annual Meeting") must be received by the Corporate Secretary of Peoples no later than November 13, 2026, to be eligible for inclusion in Peoples' Proxy Statement, form of proxy, Notice of Annual Meeting of Shareholders and Notice of Internet Availability, as applicable, relating to the 2027 Annual Meeting. Peoples will not be required to include in its Proxy Statement, form of proxy, Notice of Annual Meeting of Shareholders, or Notice of Internet Availability, as applicable, a shareholder proposal that is received after that date or that otherwise fails to meet the requirements for shareholder proposals established by the applicable SEC rules. In addition, in order to comply with the universal proxy rules, shareholders who intend to solicit proxies for the 2027 Annual Meeting in support of director nominees other than the Peoples Board's nominees must provide notice to Peoples that sets forth the information required by Rule 14a-19 under the Securities Exchange Act of 1934, as amended (the "Exchange Act"), no later than February 23, 2027.

**Peoples Bancorp Inc.**

The SEC has promulgated rules relating to the exercise of discretionary voting authority under proxies solicited by the Board. If a shareholder intends to present a proposal at the 2027 Annual Meeting without inclusion of that proposal in Peoples' proxy materials, and does not notify the Corporate Secretary of Peoples of the proposal by January 27, 2027, or if Peoples meets other requirements of the applicable SEC rules, the proxies solicited by the Board for use at the 2027 Annual Meeting will confer discretionary authority to vote on the proposal should it then be raised at the 2027 Annual Meeting.

In each case, written notice must be given to Peoples' Corporate Secretary, at the following address: Peoples Bancorp Inc., 138 Putnam Street, P.O. Box 738, Marietta, Ohio 45750-0738, Attention: Corporate Secretary.

Shareholders desiring to nominate candidates for election as directors at the 2027 Annual Meeting must follow the procedures described in the section captioned "**CORPORATE GOVERNANCE AND BOARD MATTERS - Nominating Procedures**."

**VOTING INFORMATION**

**Who can vote at the Annual Meeting?**

Only holders of common shares of record at the close of business on February 23, 2026, are entitled to receive notice of and to vote at the Annual Meeting. At the close of business on February 23, 2026, there were 35,917,291 common shares outstanding and entitled to vote. Other than the common shares, there are no voting securities of Peoples outstanding. All voting at the Annual Meeting will be governed by our Amended Articles of Incorporation, our Code of Regulations and the General Corporation Law of the State of Ohio.

Each common share entitles the holder thereof to one vote on each matter to be voted upon at the Annual Meeting. There is no cumulative voting with respect to the election of directors.

**How do I attend and participate in the Annual Meeting?**

We will be hosting the Annual Meeting live via the internet. You will not be able to attend the Annual Meeting in person. Any shareholder can listen to and participate in the Annual Meeting live via the internet at www.proxydocs.com/pebo. The webcast will start at 10:00 a.m., Eastern Daylight Saving Time, on April 23, 2026. Shareholders of record (also known as registered shareholders) may vote and submit questions while connected to the Annual Meeting on the internet.

Instructions on how to register for and participate in the Annual Meeting, including how to demonstrate proof of ownership of Peoples common shares, are posted at www.proxydocs.com/pebo.

We recommend that you register at least one hour before the Annual Meeting to ensure ample time to complete the registration procedures and receive your unique link to the virtual meeting via confirmation e-mail. A replay of the Annual Meeting audio webcast will be available on our website for approximately one year following the Annual Meeting.

You do not need to attend the Annual Meeting to vote. Even if you plan to attend the Annual Meeting, please submit your vote in advance as instructed in this Proxy Statement.

**What is a Notice of Internet Availability?**

In accordance with rules adopted by the SEC, instead of mailing a printed copy of our proxy materials to each shareholder of record, we are permitted to furnish our proxy materials, including the Notice of Annual Meeting of Shareholders, this Proxy Statement, the form of Proxy Card and our 2025 Annual Report, by providing access to such documents over the internet. Generally, shareholders will not receive printed copies of the proxy materials **<u>unless</u>** they request them.

A Notice of Internet Availability that provides instructions for accessing our proxy materials over the internet was mailed directly to registered shareholders. The Notice of Internet Availability also provides instructions regarding how registered shareholders may vote their common shares over the internet. Registered shareholders who prefer to receive a paper or e-mail copy of our proxy materials must follow the instructions provided in the Notice of Internet Availability for requesting such materials.

*The Notice of Internet Availability only identifies the items to be voted on at the Annual Meeting. You cannot vote by marking the Notice of Internet Availability and returning it. The Notice of Internet Availability provides instructions on how to cast your vote*.**

A notice that directs beneficial owners of our common shares to the website where they can access our proxy materials will be forwarded to each beneficial shareholder by the brokerage firm, bank or other shareholder of record that is considered the registered shareholder with respect to the common shares of the beneficial shareholder. Such brokerage firm, bank or other shareholder of record will also provide each beneficial owner of our common shares with instructions on how the beneficial shareholder may request a paper or e-mail copy of our proxy materials.

**What is the difference between holding common shares as a registered shareholder and as a beneficial owner?**

If, at the close of business on February 23, 2026, your common shares were registered directly in your name with our transfer agent, Shareowner Services, you are considered a registered shareholder with respect to those common shares, and the Notice of Internet Availability or proxy materials were sent directly to you. As a registered shareholder, you may vote your common shares electronically at the Annual Meeting or you may vote your common shares prior to the Annual Meeting by submitting a proxy or by voting via the internet or by telephone.

If, at the close of business on February 23, 2026, your common shares were held in an account at a brokerage firm, bank or other similar organization, then you are the beneficial owner of common shares held in "street name" and a notice directing you to the website where you can access our proxy materials is being forwarded to you by that organization. The organization holding your account is considered the registered shareholder for purposes of voting at the Annual Meeting. As a beneficial owner, you have the right to direct that organization how to vote the common shares in your account. If that organization is not given specific direction, common shares held in the name of that organization may not be voted and will not be considered as present and entitled to vote on any matter to be considered at the Annual Meeting other than the ratification of the appointment of Peoples' independent registered public accounting firm. Please direct your brokerage firm, bank or other similar organization how to vote your common shares following the instructions provided by that organization.

**How do I vote my common shares?**

If you are a registered shareholder (*i.e*., you hold your common shares of record), you may vote your common shares using one of the following methods (please also see the information provided above and below concerning the difference in how to vote if you hold common shares beneficially through a brokerage firm, bank or other nominee, instead of as the registered shareholder ‒ beneficial holders should follow the voting instructions provided by their respective nominees):

• Vote over the internet.

&nbsp;&nbsp;&nbsp;&nbsp;◦ Before the Annual Meeting: Go to www.proxypush.com/pebo.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;▪ You can use the internet 24 hours a day, seven days a week, to transmit your voting instructions and for electronic delivery of information until the polls close during the Annual Meeting. Have your Notice of Internet Availability or your Proxy Card (if you requested a printed copy of our proxy materials) in hand when you access the website and follow the instructions to obtain your records and create an electronic voting instruction form.

&nbsp;&nbsp;&nbsp;&nbsp;◦ During the Annual Meeting: Go to www.proxydocs.com/pebo.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• You may attend the Annual Meeting via the internet and vote during the Annual Meeting. Have the information printed in the designated box at the top of your Notice of Internet Availability or your Proxy Card (if you requested a printed copy of our proxy materials) available and follow the instructions.

• Vote by Telephone. Call 1-866-883-3382.

&nbsp;&nbsp;&nbsp;&nbsp;◦ You can use any touch-tone telephone to transmit your voting instructions until the polls close during the Annual Meeting.

**Peoples Bancorp Inc.**

• Submit a Proxy Card by mail.

&nbsp;&nbsp;&nbsp;&nbsp;◦ If you received a printed copy of our proxy materials, you may submit your vote by completing, signing and dating your Proxy Card and returning it in the postage-paid envelope to Shareowner Services, P.O. Box 64945, St. Paul, Minnesota 55164-0945. Sign your name exactly as it appears on the Proxy Card. Proxy Cards submitted by mail must be received no later than April 22, 2026, to be voted at the Annual Meeting.

If, prior to the Annual Meeting, you vote via the internet or by telephone, your electronic vote authorizes the named proxy holders in the same manner as if you signed, dated and returned a Proxy Card. If, prior to the Annual Meeting, you vote via the internet or by telephone, do not return a Proxy Card unless you intend to revoke your previously submitted internet or telephone vote.

**If I am a shareholder holding common shares in "street name," how do I vote?**

If you hold your common shares in "street name," you should have received a notice of internet availability of proxy materials or voting instructions from the brokerage firm, bank or other nominee holding your common shares. You should follow the instructions in the notice of internet availability of proxy materials or voting instructions provided by your broker or other nominee in order to instruct your broker or other nominee on how to vote your common shares. The availability of telephone and internet voting will depend on the voting process of your broker or other nominee.

**How do I vote if my common shares are held through the Peoples Bancorp Inc. Retirement Savings Plan?**

If you participate in the Peoples Bancorp Inc. Retirement Savings Plan (the "Retirement Savings Plan"), you will be entitled to instruct the trustee of the Retirement Savings Plan how to vote common shares that have been allocated to your account. If you are such a participant, you will receive a Notice of Internet Availability that provides instructions for accessing our proxy materials over the internet for the common shares allocated to your account in the Retirement Savings Plan. The Notice of Internet Availability also provides instructions on how you may request a paper or e-mail copy of our proxy materials. You may vote the common shares allocated to your account by following the instructions stated on your Notice of Internet Availability or on your Proxy Card (if you requested a paper copy of our proxy materials). If you do not provide voting instructions to the trustee of the Retirement Savings Plan by 11:59 p.m., Central Daylight Saving Time, on April 19, 2026, the trustee will not vote the common shares allocated to your account.

**How will my common shares be voted?**

Those common shares represented by properly-authenticated internet or telephone voting instructions that are submitted prior to the deadline for doing so or a properly-executed Proxy Card (if you requested a paper copy of our proxy materials) that is received no later than April 22, 2026, and not subsequently revoked, will be voted in accordance with your instructions by your "proxies" (the individuals named in the voting instructions or on your Proxy Card). If you timely submit a valid Proxy Card prior to the Annual Meeting, or timely submit your voting instructions via the internet or by telephone, but do not complete the Proxy Card or voting instructions, your proxies will vote your common shares as recommended by the Board, except in the case of broker non-votes, where applicable, as follows:

• "**FOR**" the election as Peoples directors of the 11 nominees listed on pages [21](#ie4918d8a029e40428ac76ab486476da9_133) through [25](#ie4918d8a029e40428ac76ab486476da9_136) under "**PROPOSAL NUMBER 1: ELECTION OF DIRECTORS**";

• "**FOR**" the approval of the non-binding advisory resolution to approve the compensation of Peoples' named executive officers as disclosed in this Proxy Statement; and

• "**FOR**" the ratification of the appointment of Ernst & Young LLP as Peoples' independent registered public accounting firm for the fiscal year ending December 31, 2026.

***No appraisal or dissenters' rights exist for any action proposed to be taken at the Annual Meeting.*** If any other matters are properly presented for voting at the Annual Meeting, the individuals appointed as proxies will vote on those matters, to the extent permitted by applicable law, in accordance with their best judgment.

**How do I revoke or change my vote after submitting my proxy?**

Registered shareholders who submit proxies retain the right to revoke them at any time before they are exercised. Unless revoked, the common shares represented by such proxies will be voted at the Annual Meeting. If you are a registered shareholder, you may revoke or change your vote at any time before the closing of the polls during the Annual Meeting by:

• filing a written notice of revocation with the Corporate Secretary of Peoples at 138 Putnam Street, P.O. Box 738, Marietta, Ohio 45750-0738, which must be received no later than April 22, 2026;

• executing and returning a new Proxy Card (if you requested a paper copy of our proxy materials) with a later date – only your latest completed, signed and dated Proxy Card received by April 22, 2026, will be counted;

• submitting a later-dated vote by telephone or via the internet ‒ only your latest telephone or internet voting instructions received prior to the closing of the polls during the Annual Meeting will be counted; or

• participating in the Annual Meeting live via the internet and voting again.

***Participation in the virtual Annual Meeting will not, by itself, revoke your proxy.*** The last-dated Proxy Card or voting instructions you submit (by any means) will supersede all previously-submitted Proxy Cards and voting instructions. If you hold your common shares in "street name" and instructed your brokerage firm, bank or other nominee to vote your common shares and you would like to revoke or change your vote, then you must follow the instructions received from your nominee to revoke or change your vote.

**If I vote in advance, can I still participate in the Annual Meeting?**

Yes. You are encouraged to vote promptly, by submitting your voting instructions via the internet before or during the Annual Meeting, or by telephone, or by returning your Proxy Card (if you requested a paper copy of our proxy materials), so that your common shares will be represented at the Annual Meeting. However, appointing a proxy or submitting voting instructions does not affect your right to participate in the Annual Meeting and vote your common shares if you are a shareholder of record.

**What constitutes a quorum and what is the vote required with respect to the proposals to be considered at the Annual Meeting?**

Under Peoples' Code of Regulations, a quorum is a majority of the voting shares of Peoples then outstanding and entitled to vote at the Annual Meeting. Other than the common shares, there are no voting shares outstanding. Common shares may be voted online during the Annual Meeting or represented by proxy at the Annual Meeting. Both abstentions and broker non-votes are counted as being present for purposes of determining the presence of a quorum. There were 35,917,291 common shares outstanding and entitled to vote on February 23, 2026, the record date for the Annual Meeting. A majority of the outstanding common shares, or 17,958,647 common shares, voted by telephone or online before or during the Annual Meeting or represented by proxy, will constitute a quorum. A quorum must exist to conduct business at the Annual Meeting.

If a proposal is routine, a broker holding common shares for a beneficial owner in street name may vote on the proposal without receiving instructions from the beneficial owner. If a proposal is non-routine, a broker may vote on the proposal only if the beneficial owner has provided voting instructions. A "broker non-vote" occurs when a broker holding common shares for a beneficial owner is unable to vote on a proposal because the proposal is non-routine and the beneficial owner has not provided any voting instructions.

The ratification of the appointment of Peoples' independent registered public accounting firm is the only routine proposal. Each of the other proposals is a non-routine proposal on which a broker may vote only if the beneficial owner has provided voting instructions.

The following table sets forth the votes required, and the impact of abstentions and broker non-votes, if any, on the four proposals:

---

| | | |
|:---|:---|:---|
| **Item** | **Vote Required** | **Impact of Abstentions and**<br>**Broker Non-Votes, if any** |
| Election of Directors | Under Ohio law and Peoples' Code of <br>Regulations, the 11 nominees for <br>election as directors of Peoples receiving the greatest number of votes "**FOR**" their election will be elected as directors of Peoples. | • Common shares as to which the <br>authority to vote is withheld will be <br>counted for quorum purposes, but will not affect whether a nominee has received sufficient votes to be elected as a director. However, common shares to which the authority to vote is withheld will be treated as a vote against the nominee for the purpose of the majority vote standard provisions in our Corporate Governance Guidelines.<br>• Broker non-votes will not count as a vote on the proposal and will not <br>affect the outcome of the vote. |
| Approval of Non-Binding <br>Advisory Resolution to <br>Approve Compensation of <br>Peoples' Named Executive <br>Officers | The affirmative vote of a majority of the common shares represented at the Annual Meeting, in person or by proxy, and entitled to vote on the proposal, is required to approve the non-binding advisory resolution to approve the compensation of Peoples' named executive officers as disclosed in this Proxy Statement. | • Abstentions have the same effect as a vote "**AGAINST**" the proposal.<br>• Broker non-votes will not be counted in determining whether the proposal has been approved. |
| Ratification of Appointment <br>of Independent Registered <br>Public Accounting Firm | The affirmative vote of a majority of the common shares represented at the Annual Meeting, in person or by proxy, and entitled to vote on the proposal, is required to ratify the appointment of Ernst & Young LLP as Peoples' independent registered public accounting firm for the fiscal year ending December 31, 2026. | • Abstentions have the same effect as a vote "**AGAINST**" the proposal. |

Peoples' policy is to maintain confidentiality with respect to Proxy Cards, ballots, voting instructions submitted electronically and telephonically and voting tabulations that identify individual shareholders. However, exceptions to this policy may be necessary in some instances to comply with applicable legal requirements and, in the case of any contested proxy solicitation, to verify the validity of proxies presented by any person and the results of the voting. Inspectors of election and any employees associated with processing Proxy Cards or ballots, reviewing voting instructions submitted electronically and telephonically and tabulating the vote must acknowledge their responsibility to comply with this policy of confidentiality.

**Who pays the costs of proxy solicitation?**

This solicitation of proxies is being made on behalf of the Board. Peoples will pay the costs of soliciting proxies on behalf of the Board, other than the internet access or telephone usage fees, which may be charged to shareholders when voting electronically or by telephone. In addition to mailing the Notice of Internet Availability (or, if applicable, paper copies of the proxy materials) to registered shareholders as of the close of business on February 23, 2026, the brokerage firms, banks and other nominees holding our common shares for beneficial owners of such common shares must provide a notice as to where the beneficial owners can access our proxy materials in order that such common shares may be voted. Solicitation may also be made by directors, officers and employees of Peoples and

our subsidiaries by further mailings, telephone, electronic mail, facsimile, or personal contact. Directors, officers and employees who help us in the solicitation will not be specifically compensated for those services, but they may be reimbursed for their out-of-pocket expenses incurred in connection with the solicitation. Peoples will reimburse its transfer agent, as well as brokerage firms, banks and other nominees, for their reasonable out-of-pocket expenses in forwarding the proxy materials to the beneficial owners.

**SECURITY OWNERSHIP OF CERTAIN BENEFICIAL OWNERS AND MANAGEMENT**

**DELINQUENT SECTION 16(a) REPORTS**

**(Section 16(a) Beneficial Ownership Reporting Compliance)**

Section 16(a) of the Exchange Act requires that Peoples' directors and executive officers, and any persons beneficially owning more than 10 percent of Peoples' outstanding common shares, file statements (also referred to as reports) with the SEC reporting their initial beneficial ownership of common shares and any subsequent changes in their beneficial ownership. Peoples is required to disclose in this Proxy Statement any late reports, if any reports were not filed within the time periods mandated by the SEC. Based solely on Peoples' review of (i) Section 16(a) reports filed electronically with the SEC on behalf of these persons for their transactions during Peoples' 2025 fiscal year and (ii) written representations received from these persons that no other Section 16(a) reports were required to be filed by them for transactions during Peoples' 2025 fiscal year (including no Form 5), Peoples believes that all Section 16(a) filing requirements applicable to Peoples' executive officers and directors, and persons holding more than 10 percent of Peoples' outstanding common shares, were complied with, except that W. Glenn Hogan, a Peoples director, filed late a Form 4 reporting the purchase of 1,000 common shares, which occurred October 30, 2025, and was reported on November 4, 2025.

**TRANSACTIONS WITH RELATED PERSONS**

During the 2025 fiscal year, Peoples Bank entered into banking transactions (including deposit, trust or other banking services and/or loans and loan commitments) with certain executive officers and directors of Peoples, with members of their respective immediate families and with corporations or organizations as to which directors of Peoples serve as executive officers or beneficially own more than 10% of the equity securities. It is expected that similar banking transactions will be entered into in the future. Any loans to these persons (i) were made in the ordinary course of business, (ii) were made on substantially the same terms, including interest rates charged and collateral required, as those prevailing at the time for comparable loans with persons not related to Peoples or Peoples Bank, and (iii) did not involve more than the normal risk of collectability or present other unfavorable features to Peoples or Peoples Bank. As of the date of this Proxy Statement, none of the loans described in this paragraph are or would be disclosed as past due, nonaccrual or modified for borrowers experiencing financial difficulty in Peoples' consolidated financial statements and each loan was performing in accordance with its original terms.

The loans described in the immediately preceding paragraph were subject to Peoples Bank's written policies, procedures and standard underwriting criteria applicable to loans generally, and were made in accordance with the Federal Reserve Board's Regulation O ("Regulation O") requiring loans to executive officers and directors of Peoples Bank in excess of $500,000 to be approved by the full Board of Directors of Peoples Bank.

**Peoples Bancorp Inc.**

The Board has adopted the Peoples Bancorp Inc. Related Person Transaction Policy (the "Related Person Transaction Policy"), a copy of which is posted under the "Governance – Governance Documents" tab on the "Investor Relations" page of Peoples' website at www.peoplesbancorp.com. The purpose of the Related Person Transaction Policy is to set forth the guidelines and procedures under which certain related person transactions must be reviewed and approved or ratified by the Audit Committee, as appropriate.

A "related person transaction" is any transaction, arrangement or relationship, or any series of similar transactions, arrangements or relationships, in which: (1) Peoples or one of our subsidiaries was, is or will be a party or participant, or had, has or will have a direct or indirect interest; (2) the amount involved exceeds or is expected to exceed $120,000, or if the limitations prescribed by Regulation O apply, such lesser amount, if any, as may be prescribed by Regulation O; and (3) a related person had, has or will have a direct or indirect interest. A "related person" is a person who is or was an executive officer, a director, or a nominee for election as a director at any time since the beginning of Peoples' last fiscal year or a five percent shareholder of Peoples at the time of the occurrence or at any time during the existence of the transaction, and their respective immediate family members. Related person transactions deemed pre-approved or ratified, as appropriate, include:

• any transaction where the related person's interest arises solely from the ownership of common shares if all shareholders receive the same benefit on a pro rata basis;

• any transaction involving compensation to an executive officer of Peoples if the executive officer is not an immediate family member of another executive officer or of a director of Peoples and the compensation has been approved, or recommended to the Board for approval, by the Compensation Committee;

• any transaction involving compensation to Peoples' directors if the compensation is required to be reported pursuant to Item 402(k) of SEC Regulation S-K;

• any extension of credit by Peoples Bank to an immediate family member of a related person, or extension of credit in respect of which an immediate family member of a related person has an interest, if the extension of credit is not subject to Regulation O and meets certain terms specified in the Related Person Transaction Policy;

• any transaction where the related person's interest derives solely from the related person's position as a director of another corporation or organization that is a party to the transaction;

• any transaction where the related person's interest derives solely from the related person's direct or indirect ownership of less than 10% of the equity interest in another person (other than a partnership) which is a party to the transaction or ownership of a limited partner interest of less than 10% of the partnership and the related person is not a general partner and does not hold another position in the partnership, with the determination of whether the ownership threshold is exceeded made in accordance with the terms of the Related Person Transaction Policy;

• any transaction involving a related person where the rates or charges involved in the transaction are determined by competitive bids; and

• any transaction with a related person involving services by Peoples Bank as a bank depository of funds, transfer agent, registrar, trustee under a trust indenture, or similar services provided in the ordinary course of the business of Peoples Bank and on substantially the same terms as then prevailing for comparable services provided to persons not related to Peoples Bank.

Under the Related Person Transaction Policy, all related person transactions not otherwise pre-approved are referred to the Audit Committee for review and approval or disapproval. The Audit Committee may approve or ratify a related person transaction only if the Audit Committee determines that, under all of the circumstances, the related person transaction is in the best interest of Peoples and our subsidiaries. In making this determination, the Audit Committee will review and consider all information available to it, which the Audit Committee deems relevant, including:

• the related person's interest in the transaction;

• the approximate dollar value of the amount involved in the transaction;

• the approximate dollar value of the amount of the related person's interest in the transaction computed without regard to the amount of any profit or loss;

**Peoples Bancorp Inc.**

• whether the transaction was undertaken in the ordinary course of business of Peoples or the applicable subsidiary of Peoples;

• whether the transaction is on terms no less favorable to Peoples or the applicable subsidiary of Peoples than terms that could have been reached with an unrelated third party;

• the purpose of, and the potential benefits to Peoples or the applicable subsidiary of Peoples of, the transaction;

• the impact of the transaction on the related person's independence; and

• any other information regarding the transaction or the related person in the context of the proposed transaction that would be material to investors in light of the circumstances of the particular transaction.

**CORPORATE GOVERNANCE AND BOARD MATTERS**

**Independence of Directors**

The rules (the "Nasdaq Rules") of The Nasdaq Stock Market ("Nasdaq") require that a majority of the members of the Board be independent directors. The definition of an independent director for purposes of the Nasdaq Rules includes a series of objective criteria, which the Board has used in determining whether its members are independent.

Peoples is led by Tyler J. Wilcox, who serves as President and Chief Executive Officer and as a director, and Susan D. Rector, an independent director who serves as non-executive Chairman of the Board, a position she has held since October 2020. The Board is comprised of Mr. Wilcox and 10 non-management directors, all of whom are independent as of the date of this Proxy Statement. Peoples believes that the independent directors provide objective oversight of management performance as a key component of efficient corporate governance and overall risk management. At this time, the Board has determined that the most effective leadership structure for Peoples is for a different person to serve as each of the Chief Executive Officer and the Chairman of the Board, coupled with independent chairs of each of the Audit Committee, the Compensation Committee, the Governance and Nominating Committee and the Risk Committee. The Board regularly deliberates and discusses what it believes is the appropriate leadership structure based upon the needs of Peoples in order to provide effective oversight of management.

In addition to considering the objective criteria, as required by the Nasdaq Rules, the Board has made a subjective determination as to each independent director that no relationships exist, which, in the opinion of the Board, would interfere with such individual's exercise of independent judgment in carrying out the responsibilities of a director. In making these independence determinations, the Board has reviewed, considered and discussed each director's business and personal relationships, both direct and indirect, if any, with Peoples and our subsidiaries, and the compensation and other payments each director and such director's immediate family members have, both directly and indirectly, received from or made to Peoples and our subsidiaries and presently expect to receive from or make to Peoples and our subsidiaries. Based on that review, consideration and discussion, the Board has determined that at least a majority of its members qualify as independent directors.

The Board has further determined that each of the following current directors has no financial or personal ties, either directly or indirectly, with Peoples or our subsidiaries (other than compensation received in the individual's capacity as a director of Peoples and our subsidiaries, non-preferential banking relationships in the ordinary course of business with Peoples Bank and ownership of common shares of Peoples as described in this Proxy Statement) and thus qualifies as independent: S. Craig Beam; David F. Dierker; W. Glenn Hogan; Brooke W. James; Susan D. Rector; Kevin R. Reeves; Carol A. Schneeberger; Frances A. Skinner; Dwight E. Smith; and Michael N. Vittorio.

Tyler J. Wilcox does not qualify as an independent director because he serves as an executive officer of Peoples and Peoples Bank.

**Executive Sessions**

In accordance with applicable Nasdaq Rules, the independent directors were given the opportunity to meet in executive session during each meeting of the Board and at such other times as the independent directors deemed necessary. Each executive session is presided over by the Chairman of the Board.

**Peoples Bancorp Inc.**

**Meetings of the Board and Attendance at Annual Meetings of Shareholders**

The Board held 11 meetings during the 2025 fiscal year. Each incumbent director attended 96% or more of the aggregate of the total number of meetings held by the Board and the total number of meetings held by all committees of the Board on which he or she served, in each case during his or her period of service during the 2025 fiscal year.

Peoples encourages all director nominees to attend each annual meeting of shareholders. All of the then incumbent directors participated in Peoples' last annual meeting of shareholders held virtually on April 24, 2025.

**Environmental, Social and Governance Matters**

Our vision at Peoples is to be the "Best Community Bank in America." We are committed to conducting our business in a way that ensures that Peoples will be around for many years to come. When it comes to environmental, social and governance ("ESG") matters, our actions are guided by our core values represented by the Promise Circle, which embodies how we do business and our never-ending pursuit of creating value for our employees (or as we also often refer to them, "our associates"), our communities, our clients and our shareholders. Being true to these core values in the decisions we make and in our business practices is essential to driving sustainable long-term growth.

| The Board's Governance and Nominating Committee provides oversight of Peoples' practices and reporting with respect to ESG matters, and the Board's Risk Committee is responsible for oversight of ESG-related risks. Our executive leadership team is tasked with setting strategy and driving progress in our ESG initiatives. We believe in focusing our efforts where we can have the most impact. Consequently, our ESG areas of focus are organized around our associates, our local communities, our clients and our shareholders. By relentlessly pursuing the creation of value for all four, we will ensure the sustainability of our business for many years to come. | ![2022_Pebo_Promise Circle_OUTLINE_ProxyVersion.jpg](pebo-20260306_g5.jpg) |

We provide educational offerings to colleagues believed to be suited for leadership roles within Peoples. We survey our associates to gauge their satisfaction and to solicit feedback, and management thoroughly reviews the results. Management addresses issues raised by surveys in a timely manner and provides regular progress updates as the survey results are used to continually improve the workplace for associates. This year we expanded our medical plan offerings in response to feedback received from associates. In 2024, we launched the "PEBO Closet" where associates can donate and take used clothing items and have since it expanded it to four locations across our footprint. We also offer a total of four annual scholarships to children of associates - two with a focus on technical or trade training and two for a two-year or four-year degree. In addition, the Peoples Professional Development Associate Program provides a unique opportunity for recent college graduates to immerse themselves in the financial industry and gain valuable real-world experience.

Our focus on the well-being of our associates and on having a first-class workplace resulted in Peoples being named by Newsweek as one of America's Greatest Workplaces for Mental Wellbeing in 2024 and 2025 and as one of America's Greatest Workplaces for Women in 2025. Peoples has also been acknowledged in many of the geographical areas in its footprint, being named "Top Workplace" by The Plain Dealer and Cleveland.com, its sixth such award in the last seven years. Peoples was also named a Top Workplace by the Cincinnati Enquirer and Cincinnati.com for 2025, for the third year in a row. Peoples was recognized as a Top Workplace in Greater Louisville in 2025 by the Louisville Courier-Journal for the second year in a row, and as a Top Workplace 2025 in Greater Columbus by Columbus CEO, also for the second year in a row.

<u>Diversity & Inclusion</u>

We are committed to providing equal employment opportunities for training, compensation, transfer, promotion and other aspects of employment for all qualified applicants and associates without regard to sex, race, color, religion, national origin, age, disability, sexual orientation or veteran status. A diverse and inclusive workplace begins with our core value of "Respect for All" – treating all associates and clients with respect. Our goal is to attract, retain and develop a workforce that is diverse in background, knowledge, skill and experience. As of December 31, 2025, women represented 71% of Peoples' workforce.

![Handshake_BLUE.jpg](pebo-20260306_g8.jpg)***Communities***

At Peoples, we continually strive to use our knowledge, talents and resources to improve the quality of life in our communities. We are committed to making a positive and meaningful difference in the neighborhoods where we work and live. Therefore, we measure success not only in financial terms, but also in our ongoing actions such as

**Peoples Bancorp Inc.**

fundraising efforts, educational sponsorship, community development, food drives, and partnerships with local colleges and universities. Our charitable giving occurs in two distinct areas - financial contributions and volunteerism - both of which are of equal importance and emphasis within our organization.

<u>Financial Contributions</u>

Peoples and our foundation, Peoples Bank Foundation, Inc. (the "Foundation"), collectively contributed over $2 million in 2025 in sponsorships and donations to charitable causes and organizations within the communities we serve. Contributions were made in the areas of economic development, youth and education, human services for low to moderate income individuals, arts and culture, and environmental stewardship. Specifically, the Foundation awarded approximately $750,000 in grants and scholarships to nonprofit organizations and local students in 2025. Peoples Bank also made several donations in 2025, including $250,000 to Memorial Health Systems for a new Women and Children's Hospital and $25,000 to Sisters Health Foundation. The Foundation also partnered with Washington State College of Ohio to open the "Peoples Bank Foundation Student Market" and made a $50,000 pledge toward the project, with $25,000 being donated in 2025 to complete the pledge. Peoples Bank's commitment to arts & culture includes a multiyear agreement with the Peoples Bank Theatre in Marietta, Ohio, and Mountain Arts Center in Prestonsburg, Kentucky. Both theaters are nonprofits benefiting Appalachian communities. Since 2020, we are extremely proud that our associates have donated over $875,000 of their personal funds to local area food banks. In total, the Foundation awarded over 200 grants across eight states and Washington, D.C. in 2025. Since its inception in 2003, the Foundation has awarded over $8 million in grants and scholarships.

<u>Volunteerism</u> 

Peoples associates are encouraged to volunteer in their communities. We provide every associate with eight hours of paid time off to use for community service each year. Peoples Bank is proud to be able to support many events and organizations across our footprint including youth sports and education programs, as well as community development organizations. There are Peoples associates with backgrounds in residential lending involved with affordable housing nonprofit boards, and there are Peoples associates serving as treasurers on local food banks and pantries that serve multiple states. Our associates regularly volunteer their time with local United Way organizations and serve on boards of other local nonprofit institutions. In 2022, 2023, 2024 and 2025, we partnered with Cristo Rey High School in Columbus, Ohio, to provide internships to low-income high school students. Supporting our communities is core to our mission, and we will continue to partner with, and strengthen our relationships with, organizations that share our values.

<u>Environmentally Friendly and Sustainable Business Practices</u>

We strive to operate our business in a sustainable manner and to be good stewards of the environment. With a view to increasing efficiency and reducing waste, we are continuing to digitize manual back office and financial center functions. We also offer digital delivery of banking services and electronic bank statements to reduce the amount of paper used in our business. In addition, we employ recycling collection bins for aluminum, plastic and paper, and we recycle toner cartridges and electronic equipment. During branch renovations in 2025, we donated approximately 150 pieces of furniture to nonprofit and other organizations rather than sending these items to the landfill. We upgraded parking lot lights from high energy to LED in seven locations in 2025, and Peoples is at approximately 85% full LED lighting at all of its locations. In 2025, Peoples continued its purchase of renewable energy production for a majority of its Ohio locations. Peoples also purchased an Advanced Manufacturing (IRS Section 45x) credit related to the production of solar energy components in 2025. Going forward, we will continue to focus on reducing paper usage through digitization, waste reduction and energy and resource efficiency in our facilities.

![Clients_Sheild_BLUE.jpg](pebo-20260306_g9.jpg)***Clients***

One of our core values is Clients First. This means doing what is in the best interest and meets the needs of the client, and not pushing products. We are committed to meeting the financial needs of those in the communities we serve, including all low and moderate income and minority areas within our communities. We have consumer lending products such as our Dreams2Keys program, which helps borrowers in a low to moderate income census tract or located in a majority-minority census tract gain homeownership. We offer many ways to avoid the maintenance fee on our checking and savings products. Peoples Bank closed 535 small business loans totaling $90.4 million in 2025.

**Peoples Bancorp Inc.**

Meeting the needs of our clients also means providing excellent service and timely resolution of any issues or questions they raise. To that end, we established a Client Experience position in 2023 to streamline customer complaint management and resolution and to drive the implementation of client-focused improvements. We also made a significant investment in 2023, 2024 and 2025 in the implementation of Salesforce customer relationship management (CRM) software, enabling us to better connect with and serve our clients. In addition, in early 2024, we created an internal call center to support our client-facing associates in delivering timely and effective assistance to our clients. Since its inception, we have added three additional positions to create a Client Experience team, to further enhance capacity and responsiveness to our clients.

In 2025, Peoples received many accolades for how we take care of our clients. The following are a few notable examples:

• Recognized by Forbes as one of America's Best-In-State Banks 2025

• Finished in the top 25% in the United States in terms of SBA 7(a) approved loans

Lastly, security of client information is always a top priority for Peoples, and we have established strong governance measures to protect the privacy and security of client information to ensure compliance with all privacy and cybersecurity laws and regulations through physical, electronic and procedural safeguards. We evaluate our cybersecurity readiness through internal reviews and external audits, as well as through regulatory oversight by the Federal Reserve Bank of Cleveland and the Ohio Department of Commerce - Division of Financial Institutions.

![Shareholders_BLUE.jpg](pebo-20260306_g10.jpg)***Shareholders***

We believe that strong governance and sustainability oversight is essential to providing long-term value for our shareholders. In 2025, our stock dividend yield and stock payout ratio remained competitive as compared to our peers.

Our corporate governance program provides a foundation for operating our business in a manner that is fair, ethical and responsible. Our Corporate Governance Guidelines reflect our Board's commitment to sound and effective governance and serve as a framework for the governance of our company. Our Code of Ethics outlines our principles that help each of us make the right decisions when conducting business.

Over 90% of our directors are independent, which allows for our Board to provide objective oversight of management performance and overall risk management. Our Board is also diverse, with 55% of directors being diverse in terms of gender or race/ethnicity as of February 23, 2026. Our leadership structure consists of a different person serving as each of the Chief Executive Officer and non-executive Chairman of the Board, with the Chairman of the Board being an independent director. We believe this leadership structure allows the Board to provide effective oversight of management.

Peoples utilizes a comprehensive enterprise risk management framework to identify, assess, measure, monitor, report and control risks throughout the company, including ESG related risks. The Risk Committee is comprised of all the independent directors of the Board, in addition to Peoples' Chief Executive Officer ("CEO"), and is responsible for oversight of our risk management processes. Our management level risk committee, which consists of senior leaders at Peoples and reports directly to the Risk Committee, develops and recommends our risk appetite for approval by the Risk Committee, monitors key risk indicators and assesses and monitors current and emerging risks. Peoples' Chief Risk Officer oversees our enterprise risk management framework and reports directly to the Risk Committee and administratively to our CEO.

We believe our compensation programs and philosophy are appropriately designed to reward performance, protect the interests of our shareholders, and provide appropriate incentives to executive management, while not encouraging excessive risk taking. We believe that tying compensation to the results achieved is vital to the long-term sustainability of Peoples. For more on our executive compensation practices, see "**EXECUTIVE COMPENSATION: COMPENSATION DISCUSSION AND ANALYSIS**" beginning on page [41](#ie4918d8a029e40428ac76ab486476da9_202) of this Proxy Statement.

While we are pleased to share our ESG story, we do, however, remain conscious of the need to continuously improve our ability to create value for our associates, our communities, our clients and our shareholders. Doing so is essential to achieving our goal of being the "Best Community Bank in America." In 2026 and beyond, we will remain vigilant to

For more information on our ESG areas of focus, please visit our corporate website: https://www.peoplesbancorp.com/about-us/about-peoples/environmental-social-and-governance-esg/

**Majority Vote Standard**

We have adopted provisions in our Corporate Governance Guidelines providing that, in an election where the only nominees are those recommended by the Board, any nominee for election as a director who receives a greater number of votes "against" his or her election than votes "for" his or her election (a "Majority Withheld Vote") is to promptly tender his or her resignation to the Chairman of the Board following certification of the shareholder vote. The Governance and Nominating Committee will promptly consider the tendered resignation and will recommend to the full Board whether to accept or reject the tendered resignation no later than 60 days following the date of the shareholders' meeting at which the election occurred (the "Shareholder Meeting Date"). In considering whether to accept or reject the tendered resignation, the Governance and Nominating Committee will consider factors deemed relevant by the Governance and Nominating Committee members, including, without limitation, the director's length of service, the director's particular qualifications and contributions to Peoples, the reasons underlying the Majority Withheld Vote (if known) and whether these reasons can be cured, and compliance with stock exchange listing standards and our Corporate Governance Guidelines.

The Board will act on the Governance and Nominating Committee's recommendation no later than 90 days following the Shareholder Meeting Date. In considering the Governance and Nominating Committee's recommendation, the Board will consider the factors considered by the Governance and Nominating Committee and such additional information and factors the Board believes to be relevant. Following the Board's decision on the Governance and Nominating Committee's recommendation, Peoples will promptly disclose publicly the Board's decision whether to accept the resignation as tendered (providing an explanation of the process by which the decision was reached and, if applicable, the reasons for rejecting the tendered resignation) in a Current Report on Form 8-K filed with the SEC.

If one or more directors' resignations are accepted by the Board, the Governance and Nominating Committee will recommend to the Board whether to fill such vacancy or vacancies or to reduce the size of the Board.

Any director who tenders his or her resignation pursuant to the Majority Withheld Vote provision is not to participate in the Governance and Nominating Committee recommendation, or the Board consideration, regarding whether to accept or reject the tendered resignation. If a majority of the members of the Governance and Nominating Committee were to receive a Majority Withheld Vote at the same election, then the independent directors who are then members of the Board and did not receive a Majority Withheld Vote will automatically be appointed to a special Board committee solely for the purpose of considering the tendered resignations and will recommend to the Board whether to accept or reject the tendered resignations.

**Shareholder Communications with the Board**

Any communication to the Board or to individual directors may be mailed, in care of Peoples' Corporate Secretary, to Peoples' headquarters in Marietta, Ohio, and the mailing envelope must contain a clear notation indicating that the enclosed correspondence is a "Shareholder-Board Communication" or a "Shareholder-Director Communication" as appropriate. All such communications must identify the author as a shareholder of Peoples and clearly state whether the intended recipients are all members of the Board or certain specified individual directors. The Corporate Secretary will make copies of all such communications and circulate them to the appropriate director or directors without any screening. Any correspondence marked "personal and confidential" will be delivered by the Corporate Secretary to the intended recipient(s) without opening.

**Nominating Procedures**

Peoples has a standing Governance and Nominating Committee that has the responsibility to identify and recommend to the full Board individuals qualified to become directors. Each candidate must satisfy the eligibility requirements set forth in Peoples' Code of Regulations. To be eligible for election as a director, an individual must be a shareholder of Peoples. Peoples' Corporate Governance Guidelines require that each director establish a financial stake in Peoples by developing a meaningful ownership position in Peoples over time as is appropriate given the

**Peoples Bancorp Inc.**

director's personal financial circumstances. However, within five years after the date of his or her initial election to the Board, each director must own common shares of Peoples having a market value equal to at least three times the annual base director retainer.

Beyond the above qualifications, the Governance and Nominating Committee will consider such factors as it deems appropriate in evaluating potential individuals for Board membership, including a consideration of the individual's contribution to the diversity of the Board. When considering potential candidates for the Board, the Governance and Nominating Committee strives to assure that the composition of the Board, as well as its practices and operation, contribute to value creation and to the effective representation of Peoples' shareholders.

In considering candidates for the Board, the Governance and Nominating Committee evaluates the entirety of each candidate's credentials. The Governance and Nominating Committee believes that all members of the Board should have the highest character and integrity, a reputation for working constructively with others, sufficient time to devote to Board matters and no conflict of interest that would interfere with performance as a director. When identifying nominees to serve as directors, the Governance and Nominating Committee will consider candidates in light of Peoples' strategic plan and the current composition and needs of the Board. Factors that will be given weight in the consideration may include diversity in business and professional experience, skills, gender, ethnic background, as well as experience and/or residence in Peoples' diverse market areas. Each of these factors will be considered in order to provide the greatest benefit to the shareholders of Peoples by selecting directors with the most exemplary credentials relative to Peoples' business and markets.

As shown in the director biographical information included in the section captioned "**PROPOSAL NUMBER 1: ELECTION OF DIRECTORS – Nominees**," our directors represent a well-rounded variety of experience, background, knowledge and skills. The Board also gains from directors having a range of tenures as this provides continuity and experience as well as fresh perspective. The average tenure of our director nominees is seven years. The director nominees range in age from 47 to 74 years.

Because of the importance placed on the directors' business and professional experience and skills, a director who changes his or her principal occupation from that held when elected to the Board is expected to volunteer to resign from the Board. Although Peoples does not believe that it will be necessary in every instance that a director who makes such a change should leave the Board, the Governance and Nominating Committee is afforded the opportunity to review the appropriateness of continued Board service under the new circumstances and make a recommendation to the full Board.

If a loan from Peoples Bank to a director or to an entity controlled by a director becomes categorized as special mention, substandard or doubtful, such director must promptly resign from the Board.

A director must advise the Chairman of the Board and the Chair of the Governance and Nominating Committee in advance of accepting an invitation to serve as a director of another public company. The Governance and Nominating Committee will then review whether such other board membership may unduly impact the ability of the director to fulfill his or her responsibilities as a director of Peoples and, if so, must make a recommendation to the full Board. Generally, the Board believes that a director of Peoples should not serve on more than three public company boards of directors (including Peoples' Board).

The Governance and Nominating Committee considers candidates for the Board from any reasonable source, including shareholder recommendations, and does not evaluate candidates differently based on who has made the recommendation. The Governance and Nominating Committee has the authority under its charter to hire and pay a fee to consultants or search firms to assist in the process of identifying and evaluating director candidates.

Shareholders may recommend director candidates for consideration by the Governance and Nominating Committee by writing to the Corporate Secretary of Peoples at Peoples' executive offices in Marietta, Ohio. Such recommendation must provide the candidate's name, age, business address, residence address, principal occupation or employment, and number of common shares beneficially owned. The recommendation must also describe the qualifications, attributes, skills and/or other qualities of the recommended director candidate. A written statement from the candidate consenting to be named as a director candidate and, if nominated and elected, to serve as a director must accompany any such recommendation.

Shareholders who wish to nominate an individual for election as a director at an annual meeting of the shareholders of Peoples must comply with the provisions of Peoples' Code of Regulations regarding shareholder nominations. Shareholder nominations must be made in writing and delivered or mailed to the Corporate Secretary of Peoples not

less than 14 days nor more than 50 days prior to any meeting of shareholders called for the election of directors. However, if less than 21 days' notice of the meeting is given to the shareholders, the nomination must be mailed or delivered to the Corporate Secretary no later than the close of business on the seventh day following the day on which the notice of the meeting was mailed to the shareholders. Nominations for the 2026 Annual Meeting must be received by April 9, 2026. Each nomination must contain the following information to the extent known by the nominating shareholder:

• the name, age, business address and residence address of each proposed nominee;

• the principal occupation or employment of each proposed nominee;

• the number of shares of capital stock of Peoples beneficially owned by each proposed nominee and by the nominating shareholder; and

• any other information required to be disclosed with respect to a nominee for election as a director under the SEC's proxy rules.

Each nomination must be accompanied by the written consent of the proposed nominee to serve as a director of Peoples if elected. Nominations not made in accordance with the above requirements and Peoples' Code of Regulations will not be considered.

In addition, in order to comply with the universal proxy rules, shareholders who intend to solicit proxies for the 2027 Annual Meeting in support of director nominees other than the Peoples Board's nominees must provide notice to Peoples that sets forth the information required by Rule 14a-19 under the Securities Exchange Act of 1934, as amended (the "Exchange Act"), no later than February 22, 2027.

**Insider Trading Policy**

Peoples has adopted insider trading policies and procedures applicable to our directors, officers and employees, and has implemented processes (including a pre-clearance process administered by Peoples' General Counsel) that we believe are reasonably designed to promote compliance with insider trading laws, rules and regulations, including applicable Nasdaq listing standards. Our Insider Trading Policy prohibits engaging in transactions in securities of Peoples while in possession of material nonpublic information about Peoples and also prohibits trading on material nonpublic information regarding any other company learned in the course of working for Peoples or its subsidiaries. Our Insider Trading Policy also prohibits our employees from disclosing material, nonpublic information of Peoples, or another publicly traded company, to others who may trade on the basis of that information. Our Insider Trading Policy requires that directors and executive officers of Peoples only transact in securities of the Corporation during an open window period, subject to limited exceptions.

Peoples' Insider Trading Policy prohibits all directors, officers and employees, including our executive officers, from engaging in certain hedging transactions related to securities of Peoples held by them, including the purchase of securities of Peoples on margin, buying or selling puts or calls, trading securities of Peoples on a short-term basis, and pledging securities of Peoples as a collateral for a loan or other financial obligation.

The foregoing summary of our insider trading policies and procedures does not purport to be complete and is qualified by reference to the our Insider Trading Policy, a copy of which can be found as an exhibit to our Annual Report on Form 10-K for the fiscal year ended December 31, 2025, as well as under the "Governance - Governance Documents" tab on the "Investor Relations" page of the Peoples' website at www.peoplesbancorp.com.

**Recommendation and Vote Required**

The Board proposes that each of the nominees identified below be re-elected for a new one-year term and until the nominee's successor is duly elected and qualified, or until the nominee's earlier resignation, removal from office or death. The Governance and Nominating Committee recommended each nominee for re-election.

Peoples' Code of Regulations provides that the nominees for election as directors receiving the greatest number of votes "**FOR**" election as a director of Peoples will be elected. Except in the case of broker non-votes, common shares represented by properly-authenticated internet or telephone voting instructions, that are submitted prior to the deadline for doing so, or by properly-executed and returned Proxy Cards, that are received prior to the deadline for such receipt, will be voted as specified or, if no instructions are given, "**FOR**" the election of the Board's nominees. Common shares as to which the authority to vote is withheld will not be counted toward the election of directors, or toward the election of the individual nominees specified on the Proxy Card and in the voting instructions. However, common shares as to which the authority to vote is withheld will be treated as a vote against the nominee for the purpose of the majority vote standard provisions in our Corporate Governance Guidelines. Broker non-votes will not be counted toward the election of directors, toward the election of the individual nominees specified on the Proxy Card and in the voting instructions, or for purposes of the majority vote standard provisions.

While it is contemplated that all nominees will stand for re-election at the Annual Meeting, if one or more nominees at the time of the Annual Meeting should be unable to serve or for good cause will not serve as a candidate for re-election as a director, the individuals designated as proxy holders on the Proxy Card or in the voting instructions will have full discretion to vote the common shares represented by the proxies they hold for the re-election of the remaining nominees and for the election of any substitute nominee or nominees designated by the Board following recommendation by the Governance and Nominating Committee, unless the Board reduces the number of directors to be elected. If any substitute nominees are designated, Peoples will file an amended proxy statement that, as applicable, identifies the substitute nominees, discloses that such nominees have consented to being named in the revised proxy statement and to serve if elected, and includes certain biographical and other information about such nominees required by applicable SEC rules. The Board knows of no reason why any of the nominees named above would be unavailable or unable to serve if re-elected to the Board.

There are no family relationships among any of the directors, nominees for election as a director and executive officers of Peoples.

**Board Skills**

The matrix below, as well as the descriptions following the matrix, summarize the skills and experience of the Board's nominees for election at the Annual Meeting. The Governance and Nominating Committee utilizes a matrix approach that tracks each director's and director nominee's experience and qualifications in a tabular format to assist the committee in maintaining a well-rounded, diverse and effective Board. The matrix does not encompass all of the knowledge, skills, or experiences of our directors, and the fact that a particular qualification, skill, or experience is not listed does not mean that a director does not possess it. In addition, the absence of a particular qualification, skill, or experience with respect to any of our directors does not mean the director in question is unable to contribute to the decision-making process in that area, taking into consideration the qualifications for membership on each of the standing committees of the Board. The type and degree of qualification, skill and experience listed below may vary among members of the Board.

**THE BOARD AND COMMITTEES OF THE BOARD**

The Board has adopted the Peoples Bancorp Inc. Corporate Governance Guidelines, a copy of which is posted under the "Governance – Governance Documents" tab on the "Investor Relations" page of Peoples' website at www.peoplesbancorp.com. The Board has also adopted the Code of Ethics for Directors, Officers and Employees of Peoples Bancorp Inc. and our Subsidiaries (the "Code of Ethics"), a copy of which is posted under the "Governance – Governance Documents" tab on the "Investor Relations" page of Peoples' website at www.peoplesbancorp.com.

**Committees of the Board**

The Board has five standing committees: Audit, Compensation, Executive, Governance and Nominating, and Risk. Each of the standing committees is chaired by a separate independent director. The Audit Committee and the Risk Committee are charged with the majority of the risk oversight responsibilities of the Board. In addition, the Compensation Committee evaluates, with Peoples' Chief Risk Officer, all risks posed by Peoples' executive compensation programs and makes all reasonable efforts required to limit any unnecessary risks these programs may pose to Peoples and to ensure that the programs do not encourage participants to take unnecessary or excessive risks that threaten the value of Peoples. These evaluations are conducted in accordance with guidance from applicable federal regulators. The Audit Committee, the Compensation Committee and the Risk Committee are focused on maintaining our key risks within acceptable tolerances and work in concert to provide enterprise-wide oversight. Each committee's role and its interaction with the full Board regarding the committee's oversight responsibilities are described more fully below. Through these committees and effective working relationships with management, the Board is able to effectively monitor and maintain an active role in the oversight of the key aspects of the risks to which Peoples is exposed. Peoples believes that this risk oversight structure, coupled with Peoples'

**DIRECTOR COMPENSATION**

Peoples uses a combination of cash and equity-based compensation to attract and retain qualified directors to serve on the Board. Director compensation elements are designed to:

• Align directors with long-term shareholder interests;

• Ensure Peoples can attract and retain outstanding director candidates;

• Approximate the market median director compensation (overall and by pay element) of members of the Peer Group used for executive compensation benchmarking purposes;

• Recognize the substantial time commitments necessary to oversee the affairs of Peoples; and

• Support the independence of thought and action expected of directors.

**Compensation Paid to Board Members**

***2025 Fiscal Year***

The Compensation Committee believes the combination of cash and equity-based compensation (in the form of unrestricted common shares) in Peoples' director compensation model promotes independent decision-making on the part of directors as the common shares have immediate value, unlike stock options or similar forms of equity-based awards.

The Compensation Committee reviews director compensation every two years, with the last review conducted in the fourth quarter of 2024. The Compensation Committee's review focused on director compensation reported in the proxy statements of the benchmarking peer group used to help set the pay opportunities of Peoples' named executive officers. Based on that review and the desire to have director compensation reflect the median of the peer group, changes to director compensation were recommended by the Compensation Committee and approved by the Board effective April 1, 2025.

During 2025, each director of Peoples, other than Mr. Wilcox, received a retainer paid in quarterly installments at an annual rate of $92,500 for the first quarter of 2025, which increased to an annual rate of $105,000 for the remainder of the year. Each installment of the annual retainer was paid 50% in cash and 50% in the form of the number of unrestricted common shares with an equivalent fair market value at the time of payment. The common shares issued

In 2025, the Chairs of the Compensation Committee, the Governance and Nominating Committee, and the Risk Committee each received an additional retainer at an annual rate of $7,500 through the first quarter, which increased to an annual rate of $10,000 for the remainder of the year, paid in quarterly installments. In 2025, the Chair of the Audit Committee received an additional retainer at an annual rate of $12,500 through the first quarter, which increased to an annual rate of $20,000 for the remainder of the year, paid in quarterly installments. Each installment of these additional annual retainers was paid 100% in cash.

In 2025, the Chairman of the Board received an additional retainer at an annual rate of $50,000 through the first quarter, which increased to an annual rate of $60,000 for the remainder of the year, paid in quarterly installments. Each installment of the additional annual retainer was paid 100% in cash.

All directors of Peoples are also directors of Peoples Bank. The aforementioned compensation was for service as a director of both Peoples and Peoples Bank.

The director compensation described above is reflected in the "**Director Compensation for 2025**" table found on page [37](#ie4918d8a029e40428ac76ab486476da9_190) of this Proxy Statement. The Compensation Committee believes the compensation paid to directors is commensurate with the level of responsibility and accountability of each director and is appropriate to maintain the caliber of directors necessary to promote long-term shareholder value based upon periodic review of director compensation data from the Peer Group described in the section captioned "**EXECUTIVE COMPENSATION: COMPENSATION DISCUSSION AND ANALYSIS**" beginning on page [41](#ie4918d8a029e40428ac76ab486476da9_202) of this Proxy Statement.

Mr. Wilcox received no compensation as a director of Peoples or of Peoples Bank during the 2025 fiscal year.

Directors who travel a distance of 50 miles or more one way to attend a Board or Board committee meeting of Peoples or Peoples Bank receive a $150 travel fee. A single travel fee of $150 is paid for multiple meetings occurring on the same day or consecutive days. Directors who travel a distance of 500 miles or more (round trip) to attend a Board or Board committee meeting are reimbursed for the actual cost of reasonable travel expenses including coach class airfare, car rental and other usual and customary travel expense in lieu of the $150 fee. Directors who stay overnight to attend a meeting are reimbursed for the actual cost of their overnight accommodations. Peoples believes these fees and reimbursements are reasonable and partially offset travel expenses incurred by those directors living outside the Marietta, Ohio area, where Board and Board committee meetings are typically held.

***2026 Fiscal Year***

As of the date of this Proxy Statement, the Board has not made any changes for the 2026 fiscal year to the director compensation arrangements discussed above.

**Other Information Regarding Equity-Based Compensation**

Under the 2006 Plan, the maximum aggregate dollar value with respect to equity-based award(s) that may be granted to any one non-employee director in any one fiscal year is $150,000. The full Board approves all equity-based awards made to individuals serving as non-employee directors of both Peoples and Peoples Bank. The grant date for equity-based awards (other than the annual retainer) made to non-employee directors of Peoples and Peoples Bank is typically the date of the approval by the Board or the second business day following the date on which any material information has been publicly disclosed, whichever is later. The price by which the value of equity-based awards is measured is the closing price of Peoples common shares on The Nasdaq Global Select Market<sup>®</sup> on the grant date. In 2025, no equity-based awards were granted to non-employee directors outside of their annual retainers described above.

**Deferred Compensation Plan for Directors**

Peoples maintains the Third Amended and Restated Deferred Compensation Plan for Directors of Peoples Bancorp Inc. and Subsidiaries (the "Deferred Compensation Plan for Directors"). Voluntary participation in the Deferred Compensation Plan for Directors allows a non-employee director of Peoples or of any of our subsidiaries to defer all or part of the compensation (including compensation in the form of common shares), and the federal income tax thereon, received for services provided as a director of Peoples or of one of our subsidiaries. Since 1998, directors

**Peoples Bancorp Inc.**

participating in the Deferred Compensation Plan for Directors have been permitted to allocate their deferrals within their respective bookkeeping accounts under the Deferred Compensation Plan for Directors between a cash account and a stock account. Deferrals with respect to compensation in the form of common shares are automatically deferred to the stock account. The cash account earns interest equal to Peoples Bank's three-year certificate of deposit interest rate. The stock account receives allocations to a bookkeeping account of Peoples common shares on the first business day of each calendar quarter based upon the cash portion of amounts deferred during the previous calendar quarter and the fair market value of Peoples common shares on the allocation date and is credited with subsequent cash dividends on the common shares previously allocated to the stock account (which will be similarly credited to the bookkeeping account as Peoples common shares). If a participant fails to make an election, 100% of the participant's deferrals will be allocated to the cash account. The only right a participant in the Deferred Compensation Plan for Directors has with respect to his or her cash account and/or stock account is to receive distributions upon termination of service as a director. Distribution of the deferred amounts is made in a lump sum or substantially equal annual installments over a period of up to five years, at the election of the director, beginning on the first business day of the calendar month following the earlier of the director's death or separation from service as a director. For a director who is also a "specified employee" for purpose of Section 409A on the date of the director's separation from service, the distribution will be delayed until the first business day of the seventh month following the date of separation of service. The stock account is distributed only in common shares of Peoples, and the cash account is distributed only in cash.

**All Other Compensation**

The non-employee directors are eligible to participate, at their own cost, in the medical, vision, and dental insurance plans maintained by Peoples for employees. In addition, the non-employee directors automatically receive a group term life insurance benefit, the premiums for which are paid by Peoples. This benefit is also provided for directors after their retirement from Peoples. The maximum benefit under the group term life insurance is $50,000 for directors age 65 or younger. The maximum benefit decreases by a percentage for each year beyond age 65 until it reaches a maximum payout of $5,000 at age 90.

During 2016, the Board approved the purchase of split-dollar bank-owned life insurance ("BOLI"), and all of the directors serving at the time were offered the opportunity to participate in this benefit. Those directors who elected to participate each receive, at no cost to the director, a $50,000 life insurance death benefit while serving as a director of Peoples and a $25,000 life insurance death benefit after retiring from service as a director of Peoples. As the owner of the policies, Peoples can elect to terminate this coverage at any time. Directors who joined the Board after the 2016 approval of the purchase of BOLI do not participate in this benefit (with the exception of Ms. Schneeberger, who was an employee of Peoples at that time and was not a director). During 2022, the Board approved the purchase of additional BOLI, but directors were not provided the opportunity to participate in the 2022 BOLI purchase.

**Stock Ownership Guidelines**

Peoples' Corporate Governance Guidelines require that directors establish a financial stake in Peoples by developing a meaningful ownership position in Peoples over time as is appropriate given the director's personal financial circumstances. However, within five years after the date of his or her election to the Board, each director must own common shares of Peoples having a market value equal to at least three times the annual base director retainer (cash and equity).

Under Peoples' Insider Trading Policy, all directors, officers and employees of Peoples and any of our subsidiaries are prohibited from holding Peoples' securities in a margin account or otherwise pledging Peoples' securities as collateral for a loan or other financial obligation. Such individuals are also prohibited from engaging in short sales, publicly-traded options, and hedging or monetization transactions involving Peoples' securities through the use of financial instruments such as prepaid variable forward contracts, equity swaps, collars, and exchange funds.

**Peoples Bancorp Inc.**

**PROPOSAL NUMBER 2: VOTE ON ADVISORY RESOLUTION TO APPROVE NAMED EXECUTIVE OFFICERS' COMPENSATION**

The Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010 (the "Dodd-Frank Act") and corresponding SEC rules enable Peoples' shareholders to vote to approve, on an advisory and non-binding basis, the compensation of Peoples' named executive officers as disclosed in this Proxy Statement. Accordingly, the following resolution will be submitted for shareholder approval at the Annual Meeting:

"RESOLVED, that the shareholders of Peoples Bancorp Inc. ("Peoples") approve, on an advisory basis, the compensation of Peoples' named executive officers as disclosed in Peoples' Proxy Statement for its 2025 Annual Meeting of Shareholders pursuant to Item 402 of SEC Regulation S-K, including in the section captioned "**EXECUTIVE COMPENSATION: COMPENSATION DISCUSSION AND ANALYSIS**", the section captioned "**SUMMARY COMPENSATION TABLE FOR 2025**", and the related executive compensation tables, notes and narratives."

The Board believes that Peoples' compensation policies and procedures, which are reviewed and approved by the Compensation Committee, are effective in aligning the compensation and incentives paid to Peoples' named executive officers with Peoples' short-term goals and long-term success, and that such compensation and incentives are designed to attract, retain and motivate Peoples' key executives who are directly responsible for Peoples' continued success. The Board believes that Peoples' compensation policies and practices do not threaten the value of Peoples or the investments of our shareholders, or create incentives to engage in behaviors or business activities that are reasonably likely to have a material adverse impact on Peoples. The Board further believes that Peoples' culture focuses executives on sound risk management and appropriately rewards executives for performance. The Board also believes that Peoples' compensation policies and procedures are reasonable in comparison both to Peoples' peer financial services holding companies and to Peoples' performance during the 2025 fiscal year.

Similar "Say on Pay" proposals were approved by a significant majority of the common shares voted at each of Peoples' last 17 annual meetings of shareholders.

Shareholders are encouraged to carefully review the information provided in this Proxy Statement regarding the compensation of Peoples' named executive officers in the section captioned "**EXECUTIVE COMPENSATION: COMPENSATION DISCUSSION AND ANALYSIS**" beginning on page [41](#ie4918d8a029e40428ac76ab486476da9_202) of this Proxy Statement.

The vote on the advisory resolution relates to the compensation of Peoples' named executive officers as a whole. Because your vote is advisory, the outcome of the vote will not: (i) be binding upon the Board or the Compensation Committee with respect to future executive compensation decisions, including those relating to Peoples' named executive officers, or otherwise; (ii) overrule any decision made by the Board or the Compensation Committee; or (iii) create or imply any additional fiduciary duty by the Board or the Compensation Committee. However, the Compensation Committee expects to take into account the outcome of the vote when considering future executive compensation arrangements. The current policy of the Board is to include an advisory resolution regarding approval of the compensation of Peoples' named executive officers annually. Accordingly, unless the Board modifies its policy on the frequency of future votes, the next advisory vote to approve the compensation of Peoples' named executive officers will occur at the 2027 Annual Meeting.

**Peoples Bancorp Inc.**

The affirmative vote of a majority of the common shares represented at the Annual Meeting, in person or by proxy, and entitled to vote on the proposal is required to approve the non-binding advisory resolution to approve the compensation paid to Peoples' named executive officers as disclosed in this Proxy Statement. Except in the case of broker non-votes, a proxy received by Peoples and not revoked prior to or at the Annual Meeting will be voted in favor of this non-binding, advisory resolution unless otherwise instructed by the shareholder. The effect of an abstention is the same as a vote "**AGAINST**" the proposal. Broker non-votes will not be counted in determining whether the proposal has been approved.

**EXECUTIVE COMPENSATION: COMPENSATION DISCUSSION AND ANALYSIS**

**Executive Summary of 2025 Fiscal Year Performance and Compensation**

The Compensation Committee has responsibility for establishing, implementing and continually monitoring our executive compensation program. In particular, the Compensation Committee determines the compensation of our named executive officers ("NEOs"), which included our CEO, our Chief Financial Officer ("CFO"), and our three other most highly-compensated executive officers who were serving as executive officers at the end of 2025. The NEOs for 2025 were:

• Tyler J. Wilcox, President and CEO

• Kathryn M. Bailey, Executive Vice President, CFO and Treasurer

• Hugh J. Donlon, Executive Vice President, Community Banking

• Douglas V. Wyatt, Executive Vice President, Chief Commercial Banking Officer

• M. Ryan Kirkham, Executive Vice President, General Counsel and Corporate Secretary

The Compensation Committee strives to ensure that the total compensation paid to the NEOs is reasonable, competitive and aligned with the best interests of our shareholders without encouraging excessive risk-taking.

***2025 Business Highlights***

2025 was a year of continued growth and evolution for Peoples. We remained focused on delivering strong financial performance, while continuing to build the foundation for long-term growth through operational excellence, technology investment, and a workplace culture that continues to earn national recognition.

Our financial results in 2025 reflected our commitment to consistent, disciplined performance. We achieved return on average assets above 1.00% for the fourth consecutive year, placing us among the top performing banks in the country. Our low cost of funds and strong net interest margin remained key competitive advantages. Annual net income exceeded $100 million for the fourth consecutive year, reaching $107 million in 2025. We also managed our balance sheet with care, growing total assets from $9.3 billion at year end 2024 to $9.6 billion at year end 2025. Our tangible book value continued to grow, ending 2025 at $23 per share. In addition, we continued making investments in people and technology that have prepared us to cross the $10 billion asset threshold and have set the foundation for our next stage of growth.

Our continued growth in 2025 allowed us to declare a quarterly cash dividend per common share of $0.41 during the second, third, and fourth quarters of 2025 and during the first quarter of 2026, compared to a quarterly cash dividend per common share of $0.40 during the previous four quarters.

***Goals for 2025 Incentive Awards***

The performance goals for the incentive awards based on 2025 performance were designed so that the target level of awards would be paid if we met our budgetary and related financial goals. With respect to two of our traditional performance metrics, return on average assets and diluted earnings per share, we decided for 2025 to continue to use pre-tax/pre-provision earnings, which are earnings (net income) excluding income tax expense and the provision for credit losses and excluding all gains and losses. Use of pre-tax/pre-provision earnings removes the volatility that the current expected credit losses ("CECL") accounting standard can produce with more traditional approaches to calculating these metrics. We began using this approach to our key incentive metrics in 2020. Because pre-tax/pre-

provision earnings do not capture credit losses, we also included the performance metric of net charge-offs as a percent of average total loans. The efficiency ratio is a key financial measure used to monitor expense management. It is calculated as total non-interest expense (less amortization of other intangible assets) as a percentage of fully-tax equivalent net interest income plus total non-interest income excluding all gains and losses. The following table summarizes our 2025 performance goals compared to our 2025 and 2024 actual (unadjusted) results.

| &nbsp;&nbsp;Net Charge-Offs as a Percent of Average Total Loans | 0.37% | 0.34% | 0.45% |

Our performance goals for 2025 relative to 2024 actual results reflected our expectation that we would experience purposeful and disciplined growth as we near the $10 billion asset size threshold. They reflected planned investments in technology initiatives and operational enhancements to continue building the foundation for long-term growth. They also took into account our expectation of elevated credit costs for our North Star Leasing business in 2025. Consequently, the 2025 targets for the pre-tax/pre-provision return on average assets, pre-tax/pre-provision diluted earnings per common share, efficiency ratio, and net charge-offs as a percent of average total loans were set at levels modestly better than 2024 actual results.

***2025 Actual Results vs. Performance Goals***

The following table provides a comparison of our 2025 results versus our 2025 performance goals:

We achieved between threshold and target levels of performance for each of the four corporate performance metrics applicable to our incentive awards, and our NEOs achieved, to varying degrees, their respective individual performance objectives.

Overall, we believe our performance supported incentive awards under our annual cash and equity-based incentive programs that were greater than threshold but less than target award opportunities. We believe our solid financial performance and the investments we made in 2025 position us well for growth and will ultimately drive increased shareholder value over the long term.

***2025 Compensation Actions***

Our compensation philosophy is designed to provide incentives and recognition for Peoples' execution of a strategy that increases shareholder value over the long term. Accordingly, and by design, the executive compensation received by the NEOs for 2025 generally reflected the achievement of results near the target levels of performance for the year.

A summary of our key 2025 compensation actions follows:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Mr. Wilcox's total direct compensation for 2025 performance was $1,470,858, which was an increase of 23% compared to the total direct compensation he received for 2024 performance in the amount of $1,194,195. The year-over-year increase was, in part, a reflection of Mr. Wilcox being new in his role as CEO in 2024 and the Compensation Committee moving his target pay opportunities for 2025 closer to the median of the Peer Group. Annual cash incentive and equity-based awards comprised 52% of Mr. Wilcox's total direct compensation for 2025. Total direct compensation is comprised of base salary and any cash and equity-based incentive payments earned for a given year's performance.

**Peoples Bancorp Inc.**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Cash incentive payments were awarded to the NEOs based on the 2025 results of achieving between the threshold and target levels of performance for each of the four corporate performance metrics. Awards were also based on the NEOs achieving, to varying degrees, their respective individual performance objectives.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Equity-based incentive payments were awarded to the NEOs from a pool created using 2025 results based on achieving the levels of performance described above.

***Notable Pay Practices***

We believe our compensation programs and philosophy are appropriately designed to reward performance, protect the interests of our shareholders and provide appropriate incentives to executive management, while not encouraging excessive risk-taking. We believe in tying compensation to the results achieved. Below is an overview of our pay practices, which reflect these beliefs:

• We consider peer and market data in setting pay, and we set target pay opportunities (overall and by pay element) at market median levels.

• We link pay to achieving financial performance objectives.

• We require a minimum level of corporate performance before any incentive compensation is paid to the NEOs (sometimes referred to as a circuit breaker or knockout), and we cap incentive payouts at what we believe are appropriately demanding levels of performance.

• We have a stock holding requirement with respect to equity-based compensation awarded to the NEOs, which requires that they hold at least 50% of their restricted common shares (net of common shares surrendered for tax withholding) after vesting for so long as they remain employed by Peoples.

• We have an executive incentive compensation clawback policy to ensure that incentive compensation paid to our NEOs is based on accurate financial data.

• A double trigger (*i.e.*, both a change in control and a termination of employment) is required for payment under our change in control agreements with our NEOs.

• We prohibit our NEOs from hedging or pledging their Peoples common shares, and we require that they obtain pre-clearance before trading in Peoples common shares.

• We conduct an annual risk assessment of our compensation programs. Our compensation program does not include elements that could encourage excessive risk taking.

• We hold an annual shareholder advisory "say-on-pay" vote.

• We engage an independent compensation advisor and annually review the compensation advisor's independence.

• Our Compensation Committee is comprised entirely of independent directors.

Additional information about our annual results and our compensation decisions follows. We believe this information provides guidance on how our decisions, established programs and corporate results came together in the compensation decisions made by the Compensation Committee.

***Total Shareholder Return***

The value we return to our shareholders is an important component of our compensation philosophy. Peoples' corporate performance is benchmarked against a variety of metrics in order to provide a view of the more specific performance components that combine to drive the total annual return for our shareholders. Long-term growth in total shareholder return is a tenet of our compensation strategy, as a large portion of our NEOs' compensation is paid in the form of restricted common shares, the amount of which is based on annual performance and the ultimate value of which is tied to the market price of our common shares.

**Peoples Bancorp Inc.**

The Compensation Committee and management of Peoples believe that our executive compensation programs are appropriately designed to incentivize sound and fundamental growth and profitability of Peoples, which will lead to improved returns to our shareholders. In years where we achieve our strategic goals and where actual performance meets or exceeds performance goals, compensation in the form of incentive payouts increases. When we do not meet the expectations and goals we set as a company, incentive payouts are reduced or not made at all, reflecting the design of our incentive awards.

The table below shows incentive compensation payouts for the NEOs based upon 2024 and 2025 results. Performance for 2024 and 2025 was consistent with the objectives of our strategic plan, and, therefore, incentive compensation was paid to the NEOs for 2024 and 2025 results. Incentive compensation paid for 2024 and 2025 generally reflected Peoples' performance between threshold and target levels of performance in each of those years with results for 2025 better relative to our target expectations than 2024 results compared to target expectations.

***Pay for Performance – Realizable Pay Analysis***

In assessing the alignment between pay and performance as part of its evaluation of the design and effectiveness of Peoples' executive compensation program, the Compensation Committee engaged its compensation consultant, Pay Governance, to analyze the realizable pay of Peoples' CEO and Peoples' total shareholder return ("TSR") relative to the realizable pay of the CEO and the total shareholder returns of members of the Peer Group (as defined on page [52](#ie4918d8a029e40428ac76ab486476da9_247)) for the three-year period ended December 31, 2024. Realizable pay for Peoples' CEO and peer CEOs was determined by adding: (1) aggregate base salary over the three-year period; (2) total annual cash incentives earned over the three-year period; (3) the vesting date value (as opposed to the grant date fair value disclosed in the Summary Compensation Table) of time-based long-term incentive awards granted during the three-year period (different from Peoples' stock awards which are tied to performance requirements during the vesting period); (4) any

gains realized on the exercise of options granted during the three-year period (recognizing that Peoples did not award options but some members of the Peer Group did award options) and (5) the vesting date value of any performance-based long-term incentive awards granted and earned in the three-year period. In addition, realizable pay included the value that could have been realized of any outstanding (unvested, unexercised or unearned) long-term incentives awarded during the three-year period based on Peoples' common share price as of December 31, 2024. Pay Governance used the same approach to calculate the realizable pay of the CEOs for members of the Peer Group. This enabled the Compensation Committee to compare the realizable pay of Peoples' CEO with the realizable pay of the CEOs of members of the Peer Group. Because realizable pay relies on information reported in the proxy statements of the members of the Peer Group, the latest year for which realizable pay could be calculated was 2024.

|:---|:---|
| The Compensation Committee also examined Peoples' total shareholder return relative to members of the Peer Group. This reflects the Compensation Committee's goal for the compensation program - to drive the creation of long-term value for our shareholders. As shown in the graph to the right, the realizable pay for Peoples' CEO for the three-year period ended December 31, 2024, ranked at the 45th percentile when compared to the Peer Group members (the individual members of which are identified as diamonds in the graph). The total shareholder return for Peoples over the three-year period ended December 31, 2024, ranked at the 58th percentile when compared to the Peer Group members. | ![2026 Proxy_Realizable Pay Chart MS.jpg](pebo-20260306_g13.jpg) |

---

Based on these percentile rankings, both Pay Governance and the Compensation Committee concluded that the relative realizable pay for Peoples' CEO and Peoples' relative performance as measured by total shareholder return were reasonably well aligned for the three-year period examined, consistent with one of the primary objectives of Peoples' pay program.

***Pay for Performance – Our Key Compensation Decisions***

Because we believe in tying compensation to performance, the Compensation Committee made the following decisions regarding the NEOs' compensation as a result of the performance results for 2025, performance relative to our peers and to our goals, and the level of achievement of both annual and long-term goals described below. Additionally, the Compensation Committee considered Peoples' objectives in attracting, rewarding and retaining talent within the organization and providing incentives to the NEOs to provide leadership in the execution of Peoples' strategic plan.

• CEO Compensation: Based upon the Compensation Committee's review of corporate and individual performance and market pay data for the Peer Group, Mr. Wilcox's base salary was increased from $700,000 to $735,000, effective January 1, 2026. The increase was in recognition of Mr. Wilcox's exemplary leadership of Peoples and its employees and the Compensation Committee's desire for Mr. Wilcox's base salary to approximate the median base salary of similarly-situated officers serving with members of the Peer Group, consistent with Peoples' pay philosophy.

For 2025 performance, Mr. Wilcox earned a cash incentive payment of $416,800 (59.5% of his 2025 base salary, which was between his threshold payout of 16.3% of salary and his target of 65.0%) and restricted common shares of Peoples under the equity-based long-term incentive plan with a grant date fair value of $354,058 (50.6% of his 2025 base salary, which was also below his target opportunity of 65% of salary) based on the closing price

of Peoples common shares on the grant date. The restricted common shares were granted to Mr. Wilcox on February 13, 2026 (but were based on achievement of 2025 performance goals). They are subject to both time-based and performance-based vesting in that they will vest on the third anniversary of the grant date, provided that Peoples has maintained a well-capitalized status and has positive net income for each of the fiscal years comprising the vesting period. In the event the performance criteria are not met in a given year, then the number of common shares as to which restrictions will lapse at the end of the cliff-vesting period will be reduced by one-third. Both the cash incentive payment and the restricted common shares grant were determined based on corporate and individual achievement of the threshold level or above with respect to all but one of the performance goals set by the Compensation Committee and the independent members of the full Board.

• Other NEO Compensation: Compensation decisions for the other NEOs are summarized in the table below. Based on the Compensation Committee's review of corporate and individual performance and market pay data for the Peer Group (and for other financial institutions of similar asset size, as described below in the cases of Mr. Wyatt, Mr. Kirkham and Mr. Donlon):

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;◦ Ms. Bailey's base salary was increased from $447,000 to $460,500, effective January 1, 2026;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;◦ Mr. Donlon's base salary was increased from $515,000 to $525,000, effective January 1, 2026;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;◦ Mr. Kirkham's base salary was increased from $322,000 to $332,000, effective January 1, 2026; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;◦ Mr. Wyatt's base salary was increased from $362,000 to $373,000, effective January 1, 2026;

The base salary of Ms. Bailey as of January 1, 2026, approximates the median base salary of similarly-situated officers serving with members of the Peer Group. The base salaries of the other NEOs as of January 1, 2026, approximate the median base salaries of similarly-situated officers of other financial institutions of similar asset size used in national survey data published by human resource consulting firms. Cash incentive awards were based on achievement of corporate and individual goals at varying levels from threshold to maximum. Restricted common shares were granted to each NEO on February 13, 2026, and are subject to both time-based and performance-based vesting in that they will vest on the third anniversary of the grant date, provided that Peoples has maintained a well-capitalized status and has positive net income for each of the fiscal years comprising the vesting period. In the event the performance criteria are not met in a given year, the number of common shares as to which restrictions will lapse at the end of the cliff-vesting period will be reduced by one-third.

***Advisory Vote of Shareholders*** 

The Compensation Committee considered the non-binding advisory vote of shareholders (which approved the compensation of Peoples' NEOs for the 2024 fiscal year as disclosed in the Proxy Statement for the 2025 Annual Meeting of Shareholders) and focused on continuing to design executive compensation programs intended to meet the best interests of Peoples' shareholders. Pursuant to the advisory vote in 2025, a total of 21,094,639 common shares were voted in favor of the advisory resolution to approve the NEO compensation for 2024, reflecting an approval rate of 97% of the common shares voted, including abstentions. Considering this level of support, the Compensation Committee decided to generally maintain the structure of Peoples' executive compensation program for 2025.

The discussion and analysis which follows is intended to provide shareholders with information about the results upon which the Compensation Committee relied in making compensation decisions relative to 2025 performance. The Compensation Committee believes that its actions were consistent with Peoples' compensation philosophy and objectives, demonstrating that Peoples' NEOs continue to be incentivized to achieve results in the best interests of our shareholders. The Compensation Committee has determined that Peoples' compensation policies and practices do not threaten the value of Peoples or the investments of its shareholders or create incentives to engage in behaviors or business activities that are reasonably likely to have a material adverse impact on Peoples. See the discussion of the Compensation Committee's review in the section captioned "**COMPENSATION COMMITTEE REPORT – Discussion of Risk Review and Assessment**," beginning on page [62](#ie4918d8a029e40428ac76ab486476da9_304) of this Proxy Statement.

**Compensation Philosophy and Objectives**

The overall philosophy for Peoples is to provide a compensation program that balances market, shareholder and regulatory considerations. In designing our compensation plans, we take into account both the absolute performance of Peoples, as well as relative improvement in the performance of Peoples during any given time period. The current incentive compensation awards are focused on both short-term and long-term goal achievement by Peoples through the use of cash and equity-based compensation in combinations that are driven by both annual and long-term goals and objectives for Peoples and the individual NEOs.

The goal of the compensation program for Peoples' NEOs is the same as our goal in the operation of Peoples' business – to create long-term value for our shareholders. In an effort to achieve this goal, we have designed and implemented a compensation program for the NEOs that:

• rewards them for sustained positive financial and operating performance and leadership excellence;

• avoids encouraging them to take excessive or unwarranted risks;

• aligns their interests with those of our shareholders;

• attracts qualified talent; and

• encourages strong performers to remain with Peoples for long and productive careers.

The elements of our compensation program consist of base salary, cash and equity-based incentive compensation, retirement benefits, and perquisites and other benefits. We combine the compensation elements for each NEO in a manner we believe optimizes the NEO's contributions to Peoples and our shareholders, motivates the NEO to attain the business goals set by Peoples, and rewards the NEO for attaining such goals without encouraging unnecessary and excessive risk-taking that could threaten the value of Peoples.

The primary focus of the Compensation Committee is the compensation for Peoples' executive officers. The intent is to reward all employees for continuous improvement and identification and implementation of best practices and, specifically, to establish and maintain compensation plans for executive officers to reward those employees for enhancing shareholder value through profitable revenue growth, responsible risk management, extraordinary client service, and a first class workplace. The compensation philosophy established by the Compensation Committee covers the direct forms of compensation and serves as a tool that the full Board and management use to ensure the compensation programs developed are both competitive with respect to officer compensation and reasonable within the marketplace.

• <u>Base Salary</u>: Base salaries for our CEO and CFO are benchmarked at the median of those of similarly-situated officers serving with members of Peoples' Peer Group. Base salaries of our other NEOs are benchmarked at the

median of those of similarly-situated officers serving at other financial institutions of similar asset size used in national survey data published by human resource consulting firms. Based upon individual circumstances, actual base salary levels may be higher or lower than this "market median." For the purposes of the annual incentive program, and as used herein, "base salary" is defined as the base salary compensation paid during the calendar year.

• <u>Total Cash Compensation</u>: Total cash compensation represents base salary plus any cash incentive payout received for annual performance. The objective is for total cash compensation for our CEO and CFO to be consistent with the market median of that received by similarly-situated officers serving with members of Peoples' Peer Group for achieving target performance. The objective is for total cash compensation for our other NEOs to be consistent with the market median of that received by similarly-situated officers serving with financial institutions of similar asset size used in national survey data published by human resource consulting firms, for achieving target performance. The objective is for total cash compensation for our NEOs to be at or above the 75th percentile of that received by similarly-situated officers if performance is achieved at a level significantly above target performance. Conversely, if our performance is significantly worse than target, the objective is for total cash compensation for our NEOs to be at or below the 25th percentile of that received by similarly-situated officers.

• <u>Total Direct Compensation</u>: Total direct compensation is comprised of total cash compensation plus the grant date fair value of equity-based awards. The objective is to grant equity-based awards only after performance goals for a fiscal year have been attained. Equity-based awards are granted with a three-year "cliff-vesting period," which enhances employee retention and reduces the sensitivity to short-term performance. Additionally, vesting of the restricted common shares granted under the program requires that Peoples meets performance criteria for each of the fiscal years comprising the vesting period. In the event the performance criteria are not met in a given year, the common shares as to which restrictions will lapse at the end of the cliff-vesting period are reduced by one-third. The long-term goal for total direct compensation is that the total direct compensation ranking for each NEO, compared to the total direct compensation of the similarly-situated officers, will reflect a percentile similar to that resulting when Peoples' performance, as measured by common performance measures used by the financial services industry, and especially community banks, is compared to that of the members of the Peer Group, in the case of our CEO and CFO, and of other financial institutions of similar asset size, in the case of our other NEOs. For example, if target performance is achieved at both the individual and the corporate level, it is expected that our CEO's total direct compensation will approximate the market median of CEOs serving with members of the Peer Group and that Peoples' performance under the common performance measures will generally align with the median performance of members of the Peer Group.

No specific formula is used to determine the allocation between compensation elements, as decisions regarding individual pay elements and overall target compensation levels are based on market median pay levels and our pay philosophy, which targets such levels. However, the portion of the total direct compensation that could have been earned in the form of cash and equity-based incentives at target levels of performance emphasized Peoples' focus on pay-for-performance during 2025. At 2025 target levels of performance, 56.5% of Mr. Wilcox's total direct compensation (split evenly between cash and equity-based incentives), 47.4% of Mr. Donlon's total direct compensation (comprised of 50% cash and 40% equity-based incentives), and 41.2% of the other NEOs' total direct compensation (comprised of 40% cash and 30% equity-based incentives), would have been in the form of performance-based compensation.

**Role of Executive Officers in Compensation Decisions**

The Compensation Committee makes all compensation decisions related to the NEOs of Peoples and recommends to the full Board any cash and equity-based compensation for the non-employee directors. Annually, the CEO of Peoples reviews the performance of each NEO (excluding his own) by comparing the results attained to Compensation Committee-approved goals, as well as the overall performance of Peoples as compared to Board-approved corporate performance goals. Both corporate and individual goals are defined for threshold, target and maximum levels of performance. This data forms the basis for the recommendations of the CEO to the Compensation Committee with respect to the compensation of the other NEOs, including base salary adjustments, and payout percentages (relative to base salary) for the annual cash incentive payments and equity-based incentive awards. The Compensation Committee considers the CEO's recommendations and uses its own discretion to make the final compensation decisions with respect to the NEOs, which may differ from the recommendations of the CEO.

**Setting Executive Compensation**

The Compensation Committee has the sole authority to engage the services of any compensation consultant or advisor. The Compensation Committee from time to time engages the services of an independent compensation and benefits consultant in order to ensure that Peoples provides total direct compensation that is performance-based, consistent with Peoples' philosophy and competitive with Peoples' Peer Group, its geographic peers and the financial services industry in general. In 2025, the Compensation Committee engaged Pay Governance to serve in this role. Pay Governance provided market intelligence on industry compensation trends along with views on specific compensation programs. Pay Governance's lead consultant reports directly to the Chair of the Compensation Committee. The Compensation Committee authorizes Pay Governance's work. Pay Governance's lead consultant also interacts with senior leadership of Peoples as needed to complete the work requested by the Compensation Committee. All work completed by Pay Governance was reported to the Compensation Committee. Communications between the Compensation Committee and the compensation consultant may occur through (i) direct conversations between the Chair of the Compensation Committee and the consultant, (ii) communications between the President and CEO, the Chief Human Resources Officer (who serves as the Secretary of the Compensation Committee) and/or the General Counsel and the consultant, or (iii) participation by the consultant in Compensation Committee meetings, including executive sessions with only non-employee directors present.

During 2025, Pay Governance provided information regarding market trends and practices for incentive plan design and executive compensation. At the request of the Compensation Committee, Pay Governance:

(1) provided simulations of the pay and performance tests used by proxy advisory firms to determine their support for Peoples' say-on-pay proposal;

(2) reviewed the reasonableness of Peoples' Peer Group used for pay benchmarking;

(3) analyzed the realizable pay of Peoples' CEO and Peoples' total shareholder return relative to the realizable pay of the CEOs of members of Peoples' Peer Group and the total shareholder returns of members of Peoples' Peer Group used for pay benchmarking;

(4) reviewed competitive market data to assess and benchmark the target pay opportunities of the CEO and CFO and their consistency with Peoples' pay philosophy;

(5) provided advice on changes to the design and structure of Peoples' long-term incentive program for 2026;

(6) reviewed NEO ownership of Peoples common stock and provided input on Peoples' stock ownership requirement for NEOs;

(7) reviewed regulatory developments and proxy advisory policies and trends;

&nbsp;&nbsp;&nbsp;&nbsp;(8) provided input to the Compensation Committee on the Proxy Statement; and

&nbsp;&nbsp;&nbsp;&nbsp;(9) attended several of the Compensation Committee's meetings during the year.

The Compensation Committee determined that the work of Pay Governance in 2025 did not raise any conflict of interest. Additionally, the Compensation Committee determined that Pay Governance was independent of management after considering several factors, including: (1) whether Pay Governance provided any other services to Peoples; (2) the amount of fees received from Peoples by Pay Governance as a percentage of Pay Governance's total revenue; (3) Pay Governance's policies and procedures that are designed to prevent conflicts of interest; (4) any business or personal relationship of the individual compensation consultants of Pay Governance providing services to Peoples with one or more members of the Compensation Committee; (5) the number of Peoples common shares owned by the individual compensation consultants of Pay Governance providing services to Peoples; and (6) any business or personal relationships between the executive officers of Peoples and Pay Governance or the individual compensation consultants providing services to Peoples.

***Peer Group***

As used in this Proxy Statement, the term "Peer Group" refers to the list of comparative companies selected by the Compensation Committee at any given time to serve as a market benchmark for evaluating executive pay levels and comparing pay design. In consultation with Pay Governance, the Compensation Committee determined on July 24,

(1) Since the Compensation Committee determined the peer group, Sandy Spring Bancorp, Inc. and Premier Financial Corp have merged out of existence.

The Peer Group used for 2025 compensation was comprised of 26 publicly-traded financial services holding companies with total asset sizes ranging roughly between one-half to two and one-half times the total asset size of Peoples at the time it was selected by the Compensation Committee on July 24, 2024. At that time, Peoples' asset size approximated that of the median of the Peer Group. The members of the Peer Group are headquartered in Indiana, Kentucky, Maryland, New York, Ohio, Pennsylvania, Virginia and West Virginia and serve markets and/or geographic areas similar to those of Peoples. Pay Governance reviewed the Peer Group and indicated that the companies were appropriate for comparison purposes based upon the demographic and performance filters used by the Compensation Committee to make the Peer Group selection, particularly the size and location of each institution in the Peer Group.

The Compensation Committee used the Peer Group data to analyze the overall competitiveness of the compensation of Peoples' CEO and CFO. The Compensation Committee used national survey data of similarly-sized financial institutions published by human resources consulting firms to analyze the overall competitiveness of the compensation of the other NEOs. The analyses were done by comparing (i) the relative ranking of each NEO's base salary and total direct compensation to the base salary and total direct compensation for similarly-situated officers for threshold, target and maximum levels of performance, and (ii) the level of performance achieved by Peoples compared to members of the Peer Group as defined by common performance measures used by the financial services industry and especially by community banks.

**Peoples Bancorp Inc.**

In view of the current economic and financial environment, the Compensation Committee reviewed the design and operation of Peoples' compensation arrangements for 2025, including the compensation arrangements of Peoples' NEOs, with Peoples' senior risk officer. This review included the mix of base salary and performance-based incentive compensation and the performance goals required to be attained for threshold, target and maximum levels of cash and equity-based incentive payments, along with the corresponding payout potentials. The Compensation Committee determined that these arrangements do not provide Peoples' NEOs with the incentive to engage in business activities or other behavior that would materially threaten the value of Peoples or the investment of Peoples' shareholders.

**2025 Executive Compensation Components**

For 2025, the principal components of compensation for the NEOs were:

• Base salary;

• Annual cash incentive compensation;

• Long-term equity-based incentive compensation;

• Retirement and other benefits; and

• Perquisites and other personal benefits.

***Base Salary***

The Compensation Committee believes that base salaries for our CEO and CFO should be competitive with the median of the base salaries of similarly-situated officers of members of the Peer Group and that the base salaries of our other NEOs should be competitive with the median base salaries of similarly-situated officers of other financial institutions of similar asset size used in national survey data published by human resource consulting firms. Depending on individual experience, job performance and competitive market requirements, the actual base salary for a particular NEO may be higher or lower than the median base salary for the similarly-situated officers (but still typically within plus or minus 10% of the median). Potential individual NEO base salary increases are reviewed annually by the Compensation Committee and are based on (i) the NEO's overall contribution to Peoples' performance, (ii) the NEO's attainment of specific individual business objectives during the preceding year, and (iii) adjustments, if any occur, in the overall responsibilities of the individual.

As noted previously in the section captioned "**Executive Summary of 2025 Fiscal Year Performance and Compensation**," (i) based on Peoples' 2025 financial performance, (ii) based on Peoples' compensation philosophy and objective of rewarding NEOs for enhancing long-term shareholder value and meeting Peoples' strategic objectives through their individual contributions, and (iii) based on market pay data of the Peer Group, in the case of Mr. Wilcox and Ms. Bailey, and of other financial institutions of similar asset size used in national survey data published by human resource consulting firms, in the case of the other NEOs:

• Mr. Wilcox's base salary was increased from $700,000 to $735,000, effective January 1, 2026;

• Ms. Bailey's base salary was increased from $447,000 to $460,500, effective January 1, 2026;

• Mr. Wyatt's base salary was increased from $362,000 to $373,000, effective January 1, 2026;

• Mr. Donlon's base salary was increased from $515,000 to $525,000, effective January 1, 2026; and

• Mr. Kirkham's base salary was increased from $322,000 to $332,000, effective January 1, 2026.

These base salaries approximate the median base salaries of similarly-situated officers serving with members of the Peer Group or other financial institutions of similar asset size.

***Cash and Equity-Based Incentive Program***

NEOs are eligible to earn additional compensation under the cash and equity-based incentive program. The incentive program was developed to reward performance by providing awards which increase as a percentage of base salary for relatively higher levels of performance and, conversely, by not paying awards if the absolute minimum performance goals are not met. The incentive program is designed to motivate and reward the NEOs for their

**Peoples Bancorp Inc.**

contributions to business goals that the Compensation Committee believes drive earnings and create shareholder value without encouraging unnecessary and excessive risk-taking.

<u>2025 Incentive Program Design</u>

The 2025 incentive program design was comprised of the annual incentive awards and the long-term incentive program and was unchanged from the incentive program design used by Peoples the past several years, which has been supported by Peoples' shareholders in their annual say-on-pay votes. The annual incentive awards provide for cash awards calculated based upon corporate and individual performance using the annual incentive payout percentages assigned to each participant's incentive tier. In order to participate in the incentive program for a given fiscal year, the NEO must have been employed by Peoples as of October 1st of the fiscal year and must also be employed by Peoples on either the date of the award, which occurs in February of the year following the fiscal year being measured, or on the last day of the performance measurement period in cases of retirement or termination without cause.

On February 26, 2025, the Compensation Committee approved the individual goals for Peoples' NEOs. On November 21, 2024, the full Board established the 2025 corporate incentive performance goals. The Board adopted a scorecard approach with four corporate performance components: (1) pre-tax/pre-provision return on average assets; (2) efficiency ratio; (3) pre-tax/pre-provision diluted earnings per common share; and (4) net charge-offs as a percent of average total loans. This approach resembled the one used to determine annual incentive awards since 2020.

The Board set the corporate performance goals for 2025, and the Compensation Committee approved the weighting for each component applicable to each of the NEOs as shown below.

With respect to the 2025 incentive program,Mr. Wilcox's and Ms. Bailey's corporate incentive goals were weighted at 70% and their individual performance goals were weighted at 30%. The corporate incentive goals for Mr. Wyatt were weighted at 50%, with line of business goals weighted at 25% and individual performance goals weighted at 25%. The corporate incentive goals for Mr. Donlon were weighted at 35%, with line of business goals weighted at 35% and individual performance goals weighted at 30%. This approach held Mr. Wyatt and Mr. Donlon accountable for results that were more immediately within their control and ability to influence. The corporate incentive goals for Mr. Kirkham were weighted at 25% and individual performance goals weighted at 75%. The relatively smaller percentage weighting for corporate incentive goals for Mr. Kirkham reflected his predominantly legal and compliance roles with Peoples.

The individual goals were unique to each NEO and consisted of quantitative and qualitative measures. The individual goals were designed to complement Peoples' corporate goals and strategic plan for 2025, particularly the Board's goals related to overall growth of Peoples. These individual goals, which are described below, were both quantitative and qualitative in nature and were designed to grow core earnings while managing risk, which is intended, in turn, to

promote the long-term interests of Peoples' shareholders. In addition, goals tied to the attainment of the long-term strategic plan were included in each NEO's individual performance goals. The Compensation Committee believes that these goals properly motivated the NEOs to implement and attain the long-term strategic objectives of Peoples, including overall growth and high performance in the key metrics noted in the table above.

The Compensation Committee also set an absolute minimum level of corporate performance that had to be achieved in order for the NEOs to potentially receive any payout of annual cash incentives and long-term equity-based incentives for 2025 (sometimes referred to by other institutions as a circuit breaker or knockout factor). The absolute minimum level of corporate performance provided an additional level of protection for our shareholders and was defined as both a minimum level of pre-tax/pre-provision earnings available to common shareholders of $2.65 per common share for the fiscal year and a percentage of nonperforming assets to total assets of 2% or less at the end of the fiscal year, both determined on a US generally accepted accounting principles ("US GAAP") basis. Performance below either of these levels would have resulted in no incentives being awarded for 2025 regardless of the NEOs' individual performance. We achieved these absolute minimum levels in 2025. Our pre-tax/pre-provision earnings per share was $5.17, and our percentage of nonperforming assets to total assets was 0.45% for 2025, surpassing the levels required to pay out any incentives for the year.

As noted above, Mr. Wyatt was assigned line of business goals for commercial banking, and Mr. Donlon was assigned line of business goals for community banking. For Mr. Wyatt, these goals consisted of quantitative measures related to commercial business performance, such as pre-tax, pre-provision net income for commercial banking, commercial portfolio loan growth and commercial portfolio asset quality. For Mr. Donlon, these goals consisted of quantitative measures related to community banking performance, such as pre-tax, pre-provision net income for the several business lines comprising the community banking group. The commercial banking line of business and the community banking group generally achieved results that were near target levels of performance with respect to these measures.

Annual individual performance goals were established for each NEO, the nature of which differed depending upon the NEO's job responsibilities. The individual performance goals were unique to each NEO and consisted of quantitative and qualitative measures such as:

(i)for Mr. Wilcox, setting, refining and executing the strategic direction of Peoples; hiring, retaining and developing the senior management team; building a client-focused culture; and promoting Peoples externally to shareholders, stock analysts and potential acquisition targets;

(ii)for Ms. Bailey, executing Peoples' strategic plan, balancing acquisitions and organic growth; ensuring an appropriate risk and control environment exists in areas of responsibility; articulating appropriate insights and exerting authority to drive organization performance; and actively engaging with shareholders and stock analysts;

(iii)for Mr. Donlon, ensuring use of Salesforce (customer relationship management software) by the lines of business; demonstrating improvement in sales results and overall market team performance by establishing clear, reportable metrics and holding each business accountable to business specific and cross-sell results; overseeing the specialty finance businesses to fully execute the business strategies; and ensuring integration of all acquired businesses into Peoples and coverage of all lines of business across Peoples' market areas;

(iv)for Mr. Wyatt, driving line of business adoption and utilization of Salesforce; recruiting, developing and retaining top performers; effectively managing performance of commercial bankers; executing the market team "go wide" strategy by ensuring full commercial participation in growing partner lines of business; and increasing the penetration of commercial banking clients within the trust, investments and insurance business lines; and

(v)for Mr. Kirkham, effectively using internal and qualified external resources to meet requirements of business partners; effectively advising business partners regarding identified risks; effectively managing legal spend; developing legal and compliance staff for proficiency and efficiency in their areas of responsibility; executing on regulatory compliance matters, ensuring regulator engagement and follow-up; maintaining effective relationships with the Board; contributing to meeting securities law requirements; and providing leadership and advice through all aspects of mergers and acquisitions activities.

The goals assigned to the NEOs were intended to reflect positive results for Peoples and its shareholders while ensuring that the compensation arrangements did not encourage unnecessary and excessive risk-taking that could threaten the value of Peoples. Measurement of these goals was objective and/or subjective in nature, depending

upon the respective goal. Payout percentages (expressed as a percentage of base salary) for various levels of performance are reviewed by the Compensation Committee on an annual basis.

*2025 Annual Incentive (Cash)*

There were three levels of payout potential for cash incentive awards based upon annual performance: threshold, target and maximum, with payouts for results in between these levels based on interpolation. The potential payout for target performance was intended to generally reflect market median cash incentive compensation as a percentage of base salary. The potential payouts for threshold and maximum levels of performance as a percentage of base salary were intended to generally reflect the practices of the Peer Group. The payout potentials for 2025, expressed as a percentage of base salary, were as follows:

---

| | | | |
|:---|:---|:---|:---|
| | **Threshold Payout<br>Potential** | **Target Payout<br>Potential** | **Maximum Payout<br>Potential** |
| &nbsp;&nbsp;Chief Executive Officer | 16.3% | 65.0% | 97.5% |
| &nbsp;&nbsp;Executive Vice President, Community Banking | 12.5% | 50.0% | 75.0% |
| &nbsp;&nbsp;Other Executive Officers | 10.0% | 40.0% | 60.0% |

---

The Compensation Committee retained the right to exercise discretion to increase or reduce the size of the payout of annual cash incentives based on the Compensation Committee's consideration of all relevant facts and circumstances beyond the formulaic result. The Compensation Committee did not exercise this discretion for 2025 annual cash incentives.

Incentive awards were paid after the results with respect to the corporate performance goals were determined. As discussed above, no annual cash incentive payments would have been earned by the NEOs if the absolute minimum levels of corporate performance had not been achieved.

In addition to the annual cash-based incentives, the Compensation Committee has in the past, and may in the future, award cash-based discretionary bonuses. The Compensation Committee did not award any cash-based discretionary bonuses to the NEOs for 2025.

Equity-based awards, if earned, are granted with a fair market value based on The Nasdaq Global Select Market<sup>®</sup> closing price of Peoples common shares on the date of the grant. The Compensation Committee approves equity-based grants to the NEOs and other key senior officers. The annual equity-based awards are typically reviewed and approved by the Compensation Committee in January or February. The grant date for the annual equity-based awards is typically on or within a few days of the date of the Compensation Committee meeting at which they are approved. In certain cases, the Compensation Committee approves the use of equity-based grants to new hires or current NEOs as an incentive to attract or retain executive officers or other senior management. In the event of equity-based grants for new hires, the date of grant is typically the first business day of the month following the new employee's date of hire. Peoples has no intention, plan or practice to select annual grant dates for equity-based awards in coordination with the release of material, non-public information or to time the release of such information because of award dates.

The 2025 long-term incentive program generally required each NEO to remain employed by Peoples for the full vesting period of the restricted common shares granted, subject to special vesting rules applicable in the event of disability or retirement from Peoples. This arrangement provides a valuable retention tool for the NEOs. Additionally, vesting of the restricted common shares granted under the program requires that Peoples meet the performance criteria of maintaining a well-capitalized status and reporting positive net income for each of the three fiscal years comprising the vesting period. Both events need to occur each year in order for the NEOs to ultimately vest in that portion of an award based on service through the full three-year vesting period. In the event both performance criteria are not met in a given year, the restricted common shares as to which restrictions will lapse at the end of the cliff-vesting period will be reduced by one-third. Dividends which would otherwise be received during the restriction period are accrued and paid to the recipient in the same proportion and at the same time that the underlying restricted common shares vest, if at all.

The following table shows the corporate, line of business and individual performance weightings, as well as the annual cash incentive earned and restricted common shares granted, under the 2025 incentive program for each of the NEOs.

<u>2026 Incentive Program Design</u>

On February 26, 2026, the Board established the 2026 corporate incentive performance goals for the annual (cash) incentive, the structure of which did not change from that used for 2025. On February 25, 2026, the Compensation Committee approved individual annual goals for Peoples' NEOs. The performance metrics for the 2026 goals, and their respective weightings for each of the NEOs are as follows:

For Mr. Wilcox and Ms. Bailey, the performance metrics for the 2026 goals and their respective weightings are as follows:

---

|:---|:---|
| &nbsp;&nbsp;Pre-Tax/Pre-Provision Return on Average Assets | 14.0% |

Mr. Wyatt has announced that he intends to retire from his position as Executive Vice President, Chief Commercial Banking Officer of Peoples, effective April 3, 2026. As a result, he is not participating in the 2026 incentive program.

The potential payout opportunities for threshold, target, and maximum levels of performance for the NEOs to earn cash incentive compensation for 2026 performance remain the same as they were for 2025 performance.

The long-term (equity-based) incentive program for the NEOs has been redesigned for 2026 to enhance the program's focus on long-term performance and to better align it with the practices of the Peer Group. The redesigned program features both time-based and performance-based award components, with the performance-based awards tied to Peoples' return on tangible common equity and total shareholder return performance over a three-year period relative to the results of other banks. Under the redesigned program for 2026, total target incentive payout opportunities were set at 75% and 40% for Mr. Wilcox and the other NEOs, respectively, split evenly between time-based and performance-based equity awards.

**Peoples Bancorp Inc.**

***Retirement and Other Benefits***

The NEOs participate in certain benefit programs available to all other employees of Peoples, subject to the same eligibility requirements that apply to all employees, including: (i) the Peoples Bancorp Inc. Retirement Savings Plan ("Peoples' 401(k) Plan"); (ii) the Peoples Bancorp Inc. Amended and Restated Nonqualified Deferred Compensation Plan (the "NQDC Plan"); (iii) the Peoples Bancorp Group Term Life Insurance Plan; (iv) the medical and dental insurance plans provided by Peoples; (v) Peoples' Employee Stock Purchase Plan (the "ESPP"); and (vi) split-dollar bank-owned life insurance.

<u>Peoples' 401(k) Plan</u>

The NEOs are eligible to participate in Peoples' 401(k) Plan, on the same basis as other employees. In 2025, the "company match" under Peoples' 401(k) Plan was 100% of the first 6% of an employee's contribution, the sum of which was subject to a maximum match of 6% of eligible compensation, which consists of base salary, other cash payments including non-equity incentive payments, overtime and bonus cash payments (excluding sign-on bonuses), commissions, referral fees, draws against commission in excess of commission earned, holiday, vacation, paid-time-off payments and payments made under the short-term disability plan.

<u>Nonqualified Deferred Compensation Plan</u>

On November 20, 2024, the Compensation Committee approved the NQDC Plan for continuation in 2025. Participation in the NQDC Plan is limited to a select group of management and highly-compensated employees designated annually by the Compensation Committee. The NQDC Plan is offered for the purpose of providing a vehicle for the deferral of compensation in excess of statutory limits under Peoples' 401(k) Plan for those participating in the NQDC Plan. Participants may elect to defer base salary, other cash payments including non-equity incentive payments, overtime and bonus cash payments (excluding sign-on bonuses), commissions, referral fees, draws against commission in excess of commission earned, holiday, vacation, paid-time-off payments and payments made under the short-term disability plan. After the applicable deadline, a deferral election is irrevocable for that plan year unless otherwise permitted under the NQDC Plan. Generally, a participant must submit a deferral election by December 31 of the year before services are to be performed. The deferred compensation, if any, is credited to a bookkeeping account maintained on behalf of the participant. The participant is fully vested in the bookkeeping account, which will be credited with earnings and losses based on the performance of the deemed investment selections made by the participant for the bookkeeping account. The Compensation Committee determines the deemed investments with which participants may direct that their bookkeeping accounts be credited.

Peoples may make discretionary contributions to participants' bookkeeping accounts in such amount that would have been made pursuant to Peoples' 401(k) Plan as matching contributions if all amounts selected to be deferred under the NQDC Plan had been deferred under Peoples' 401(k) Plan. Any such contributions will be credited to the participants' bookkeeping accounts each pay period with respect to compensation deferred in that pay period and will vest in accordance with the vesting schedule under Peoples' 401(k) Plan, provided that the portion of the participant's account attributed to discretionary contributions and any deemed earnings on the investment of such discretionary contributions will become fully vested in the event of a participant's retirement (as defined In the NQDC Plan), death, voluntary termination or involuntary termination without cause and will be forfeited if a participant is terminated for cause.

The amount reflected in a participant's bookkeeping account attributable to a participant's contributions for services performed prior to December 31, 2022, will be distributed in a single lump-sum payment on the January 1 immediately following the participant's separation from service unless the participant had made an initial deferral election under the NQDC Plan and elected to receive distribution of the participant's account in up to ten substantially equal annual installments beginning on the January 1 immediately following the participant's separation from service and on each January 1 thereafter. Effective September 1, 2022, each participant has been able to elect the time and form of payment that will apply to a portion of their bookkeeping account. The election must be made within the first 30 days of NQDC Plan eligibility for contributions to be credited for services performed during the first year of eligibility and by December 31 of each year in connection with contributions to be credited for services performed in the following year. Participants may elect the payment trigger, either separation from service, or a specified year that is at least three years after the year in which the services are performed (but, if the participant has a separation from service before the start of the specified year, the applicable portion of the participant's account will be paid beginning

**Peoples Bancorp Inc.**

in January of the year following the year in which the separation from service occurs). Participants may also elect the payment form, either a lump sum or installments. The number of installments that can be elected depends on whether the payment trigger is a specified year (in which case the participant can elect for annual installments to be paid over two to five years) or termination of employment (in which case the participant can elect for annual installments to be paid over two to ten years). This means that different portions of a participant's bookkeeping account may be payable at different times and in different forms.

If a participant dies before distribution has begun of the amount reflected in the participant's bookkeeping account or complete distribution has been made of the amount reflected in the participant's bookkeeping account, then the amount reflected in the participant's bookkeeping account will be distributed to the participant's beneficiary within 90 days after the participant's death.

Notwithstanding the foregoing, if a participant is a "specified employee" under Internal Revenue Code Section 409A on the date of his or her separation from service, distributions that are payable in connection with a separation from service from the participant's bookkeeping account will be delayed until the first business day of the seventh month following the date of the participant's separation of service. The first payment to be made after such delay will include the cumulative amount, if any, of any amounts which would have otherwise been paid in accordance with the participant's election. If a participant dies before distribution has begun of the amount reflected in the participant's bookkeeping account or complete distribution has been made of the amount reflected in the participant's bookkeeping account, then the amount reflected in the participant's bookkeeping account will be distributed to the participant's beneficiary within 90 days after the participant's death.

The 2025 eligibility criteria for participation in the NQDC Plan required participants to have (i) been employed by Peoples on December 31, 2024; (ii) either 2024 gross compensation of at least $300,000, or annualized 2025 current year base salary of at least $300,000, and (iii) an officer title of Vice President or higher at Peoples or any of its affiliates. Each of the NEOs met these criteria and elected to participate in the NQDC Plan during 2025.

**Peoples Bancorp Inc.**

<u>Insurance Plans</u>

The NEOs participate in the Peoples Bancorp Group Term Life Insurance Plan on the same basis as other employees. Peoples pays the premiums for all employees under this plan. If an employee dies, his or her beneficiary will be paid an amount equal to two times the employee's base salary at the time of death, up to a maximum amount of $600,000.

The NEOs are also eligible to participate in medical, vision, and dental insurance plans provided by Peoples on the same basis as other employees. The plans are contributory, and both the employees and Peoples pay for a portion of the cost of the health insurance premiums.

<u>Employee Stock Purchase Plan</u>

The NEOs are eligible to participate in the ESPP on the same basis as other employees. The ESPP is intended to comply with Sections 421 and 423 of the Internal Revenue Code. Employees are permitted to buy Peoples common shares through payroll deductions at a discount of up to 15% of the fair market value of the common shares on the last day of the applicable offering period. The Compensation Committee determines the establishment of any offering period and the dates on which any offering period will take place. The Compensation Committee established an offering period for each of the four calendar quarters in 2025. Each of the NEOs, with the exception of Mr. Wyatt, elected to participate in the ESPP during 2025.

<u>Bank-Owned Life Insurance</u>

During 2016 and 2022, the Board approved the purchase of split-dollar bank-owned life insurance ("BOLI"), and each of the NEOs with the exception of Mr. Donlon was offered and accepted coverage under this benefit. Under the terms of the split-dollar agreement, each NEO receives, at no cost to the NEO, a $50,000 life insurance benefit while employed by Peoples and a $25,000 life insurance benefit after retiring from Peoples. As the owner of the policies, Peoples can elect to terminate this coverage at any time.

***Perquisites and Other Personal Benefits***

The Compensation Committee periodically reviews the level of perquisites and other personal benefits provided to the NEOs. Consistent with Peoples' overall compensation program, the Compensation Committee believes the perquisites and other personal benefits provided to the NEOs are reasonable, modest in value and necessary to attract and retain employees for key positions, which, in turn, promotes the long-term interests of our shareholders.

Peoples maintains an Executive Health Program, which provides an opportunity for each NEO to participate, on a voluntary basis, in a comprehensive medical screening annually at the expense of Peoples. The objective of the Executive Health Program is the early identification of potential health problems and the prompt, expert treatment of any medical problems detected, thereby mitigating the negative potential impact on Peoples' financial performance or current management succession plans. Some of the NEOs participate in a program under which Peoples offers a limited reimbursement for fitness club memberships. This program is available to all employees and is part of an overall wellness initiative at Peoples. In 2025, all of the NEOs with the exception of Ms. Bailey participated in a wellness incentive program, available to all Peoples medical plan participants, which provided up to a one-time $1,250 payment to a Health Savings or Flexible Spending Account, depending upon individual compliance with the program's requirements, which included wellness-related activities.

Based on business needs, on a case-by-case basis, the Compensation Committee has granted the use of a company-paid automobile and/or country club membership to certain NEOs to further business development on behalf of Peoples and our shareholders. Personal use of a company-paid automobile is reported and taxed as income to the NEO. Expenses relating to personal use of the country club amenities are either reimbursed to Peoples by the NEO or paid directly by the NEO.

On a case-by-case basis, the Compensation Committee will approve the payment of or reimbursement to an NEO for moving expenses and temporary housing as part of the NEO's executive recruitment package.

**Peoples Bancorp Inc.**

***Change in Control Agreements***

Peoples has entered into a change in control agreement with each of the NEOs. The change in control agreements are designed to motivate the NEOs to act in the best interests of the Peoples shareholders and to promote stability and continuity of the services of the NEOs during a change in control. The change in control agreements are "double trigger" agreements that provide severance payments to an NEO only if Peoples or its successor terminates the NEO's employment without "cause" or the NEO terminates his or her employment with "good reason" after the change in control. A "double trigger" also applies to the restricted common shares awarded to the NEOs under our long-term incentive program if there is a change in control. The restricted common shares will immediately vest only if Peoples' successor refuses to assume the restricted common shares or substitute equivalent equity awards or if Peoples' successor terminates the NEO's employment without "cause" or the NEO terminates his or her employment with "good reason" after the change in control.

The Compensation Committee chose the "double trigger" to forego extra costs to Peoples or its successor if an NEO continues in the same or a similar role after the change in control, while still motivating the NEO to act in the best interests of the Peoples shareholders by providing for the NEO even if he or she would not have the same or a similar role after the change in control. We have defined compensation for the purpose of calculating the amount of severance to be the sum of the NEO's annualized monthly base salary for the calendar year in which the change in control occurs plus the average of annual cash incentives paid to the NEO over the prior three years.

The change in control agreements do not provide for payments to be "grossed up" for excise taxes. Additional information regarding the definition of a change in control, the additional event(s) that must occur in order for an NEO to receive severance compensation following a change in control, and potential payments under such agreements for the NEOs is provided in "**OTHER POTENTIAL POST-EMPLOYMENT PAYMENTS**" beginning on page [73](#ie4918d8a029e40428ac76ab486476da9_343) of this Proxy Statement.

**Tax and Accounting Implications**

***Deductibility of Executive Compensation***

Section 162(m) of the Internal Revenue Code generally prohibits Peoples from claiming a deduction on Peoples' federal income tax return for compensation in excess of $1,000,000 paid in a given fiscal year to certain current and former executive officers. While the Compensation Committee carefully considers the net cost and value to Peoples of maintaining the deductibility of all compensation, the Compensation Committee also desires the flexibility to reward NEOs and other key employees in a manner that enhances Peoples' ability to attract and retain individuals, as well as to create longer term value for shareholders. Thus, income tax deductibility is only one of several factors the Compensation Committee considers in making decisions regarding Peoples' compensation program.

***Non-Qualified Deferred Compensation***

Section 409A of the Internal Revenue Code ("Section 409A") imposes additional taxes, interest and penalties on non-qualified deferred compensation arrangements that do not satisfy the requirements of Section 409A. Peoples believes that it is administering its non-qualified deferred compensation arrangements in accordance with the requirements of Section 409A and that its non-qualified deferred compensation arrangements, including the change in control arrangements with the NEOs, comply with the regulations issued under Section 409A. We have not realized any material changes to our compensation program as a result of compliance with Section 409A.

***Accounting for Equity-Based Compensation***

Compensation costs for restricted common share awards, stock options, stock appreciation rights ("SARs") and performance units, if awarded, are measured at the fair value of these awards on their grant date. Compensation expense for time-vested awards is recognized over the required service period, generally the restriction period for restricted common share awards and the vesting period for stock options and SARs, if awarded. However, compensation expense for time-vested awards granted to employees who are eligible for retirement is recognized through the date the employee is first eligible to retire or at the grant date, whichever is later. Compensation expense for performance-based restricted common share awards and for performance units is recognized over the performance period, once management believes it is probable the performance requirements will be met. However,

**Peoples Bancorp Inc.**

compensation expense for performance-vested restricted common share awards granted to employees who are eligible for retirement is recognized through the date the employee is first eligible to retire or at the grant date, whichever is later. For all awards, only the expense for the portion of the awards expected to vest is recognized.

**Other Information**

***Stock Holding Requirement***

We have a stock holding requirement for the NEOs with respect to equity-based compensation awards. This stock holding requirement remains in effect during the entire time the individuals are employed by Peoples. The holding requirement is based upon a percentage of the "net shares" held by an individual NEO following vesting or exercise of an equity-based compensation award. Such "net shares" represent the number of common shares the NEO owns after paying for taxes through the withholding of common shares in the case of restricted common shares, or if granted in the future, after paying for the exercise price and taxes through the withholding of common shares in the case of the exercise of stock options, SARs or other similar forms of equity-based awards. Each NEO is required to maintain ownership of 50% of such net shares through the term of the NEO's employment. Other than this stock holding requirement with respect to equity-based compensation awards, we have no equity or other security ownership requirements for NEOs.

***Clawback Policy***

We have an executive incentive compensation clawback policy pursuant to which our executive officers will be required to repay or return erroneously awarded compensation, in the event of an accounting restatement (i) due to the material noncompliance of Peoples with any financial reporting requirement under the securities laws, including any required accounting restatement to correct an error in previously issued financial restatements that is material to the previously issued financial statements, or (ii) that corrects an error that is not material to previously issued financial statements, but would result in a material misstatement if the error were not corrected in the current period or left uncorrected in the current period. Pursuant to the clawback policy, we will seek recovery of incentive compensation (both cash and equity-based) paid during the three completed fiscal years of Peoples immediately preceding the restatement date that exceeds the amount of incentive compensation that otherwise would have been received had it been determined based on the restated amounts, computed without regard to any taxes paid. Our clawback policy applies to executive officers of Peoples (including the NEOs), as determined pursuant to applicable SEC and Nasdaq rules. A copy of our clawback policy is posted under the "Governance – Governance Documents" tab on the "Investor Relations" page of Peoples' website at www.peoplesbancorp.com.

***Timing of Equity Grants***

Equity-based awards are granted with a fair market value based on The Nasdaq Global Select Market<sup>®</sup> closing price of Peoples common shares on the date of the grant. The Compensation Committee approves equity-based grants to the NEOs and other key senior officers. Other employee awards may be made by either the Compensation Committee or the CEO pursuant to delegated authority. The annual equity-based awards to the NEOs are typically reviewed and approved by the Compensation Committee in January or February. The grant date for the annual equity-based awards is typically on or within a few days of the date of the Compensation Committee meeting at which they are approved. In certain cases, the Compensation Committee approves the use of equity-based grants to new hires or current NEOs as an incentive to attract or retain executive officers or other senior management. In the event of equity-based grants for new hires, the date of grant is typically the first business day of the month following the new employee's date of hire. Peoples has no intention, plan or practice to select annual grant dates for equity-based awards in coordination with the release of material, non-public information or to time the release of such information because of award dates.

***CEO Pay Ratio***

We determined our "median employee" for 2025 by: (1) calculating the annual total compensation for each of the part-time and full-time employees of Peoples or one of our subsidiaries who was employed as of December 31, 2025, except Mr. Wilcox, with annual total compensation for this purpose calculated by adding base salary and overtime pay, plus any cash incentive and equity-based incentive payments vested in 2025, plus the amount of any "company

match" under each of Peoples' 401(k) Plan and NQDC Plan, plus any wellness incentive payment; (2) ranking the annual total compensation of all employees except Mr. Wilcox from lowest to highest; and (3) identifying the middle employee in the list as the "median employee." Once the median employee was identified, we used the annual total compensation for 2025 for such employee calculated in the manner described in the preceding sentence, which allowed for the elements of compensation for the median employee to be as comparable as possible to the elements of the annual total compensation of Mr. Wilcox. We then used Mr. Wilcox's annual total compensation for 2025 as disclosed in the "**SUMMARY COMPENSATION TABLE FOR 2025**" appearing on page [64](#ie4918d8a029e40428ac76ab486476da9_307) of this Proxy Statement. The calculations yielded the following numbers and ratio:

---

| | |
|:---|:---|
| • Annual total compensation of Mr. Wilcox | $1500327 |
| • Median employee's annual total compensation | $60276 |
| • Ratio of annual total compensation of Mr. Wilcox to the median employee's annual total compensation | 24.89 to 1.0 |

---

**Summary**

The Compensation Committee believes that the best measure of whether the executive compensation program is achieving its intended goals is to look at the long-term performance of Peoples, as well as the relative changes in performance during any given time period. Peoples' NEOs received payouts under the incentive compensation program based upon the levels of corporate and individual performance achieved for 2025. In light of the results previously described in this "**COMPENSATION DISCUSSION AND ANALYSIS**," the Compensation Committee believes Peoples' compensation program for Peoples' NEOs continues to be aligned with the interests of our shareholders. The incentive compensation program is a performance-based system that provides a balanced foundation for strong and effective leadership into the future and ensures alignment with long-term shareholder interests without encouraging unnecessary and excessive risk-taking that could threaten the value of Peoples.

**COMPENSATION COMMITTEE REPORT**

The Compensation Committee has reviewed and discussed the disclosures included under the caption "**EXECUTIVE COMPENSATION: COMPENSATION DISCUSSION AND ANALYSIS**" required by Item 402(b) of SEC Regulation S-K with management and, based on such review and discussion, the Compensation Committee recommended to the full Board that the section captioned "**EXECUTIVE COMPENSATION: COMPENSATION DISCUSSION AND ANALYSIS**" be included in this Proxy Statement and incorporated by reference into Peoples' Annual Report on Form 10-K for the fiscal year ended December 31, 2025.

**Discussion of Risk Review and Assessment**

Peoples' Executive Vice President, Chief Risk Officer, conducted an assessment of Peoples' 2025 compensation programs and has reviewed, evaluated and discussed the assessment and the compensation programs with the Compensation Committee. The most recent review and discussion with the Compensation Committee with respect to Peoples' 2025 compensation programs occurred on October 20, 2025, and covered the senior management and executive compensation plans in which the NEOs were eligible to participate. The review of these plans took into consideration: (i) products and services incented; (ii) the risk time horizon of those products and services; (iii) incentives paid as a percentage of total revenue; and (iv) incentives paid as a percentage of each participant's total compensation. Broad-based welfare and benefit plans that do not discriminate in scope, terms or operation in favor of NEOs were excluded from the review.

The Compensation Committee believes that Peoples' overall compensation practices for its NEOs, which include the following elements, limit the ability of these officers to benefit from taking unnecessary and excessive risks:

• Balance between base salary, and cash and equity-based incentive compensation opportunities;

• Maximum payouts which limit overall payout potential;

• Balance between short-term (cash) and long-term (equity-based) incentive compensation opportunities;

**Peoples Bancorp Inc.**

• Use of a balanced scorecard approach in setting performance goals with interacting, complementary incentive objectives that discourage emphasis on any single objective;

• Grants of only full value equity awards in respect of potential equity-based long-term incentive compensation;

• Awards of restricted common shares with a performance-based vesting requirement based upon the achievement of minimum performance criteria by Peoples;

• Requirement that NEOs hold a meaningful portion of their vested equity awards for as long as they remain employed by Peoples; and

• Peoples' tone at the top and culture of ethically doing the right thing.

In addition, the Compensation Committee believes there are controls around incentive programs for all employees that effectively discourage unnecessary and excessive risk-taking. All employee incentive programs allow for management discretion (or Compensation Committee discretion in the case of the incentive program in which NEOs are eligible to participate) to reduce or eliminate any award. The Compensation Committee reviews and approves all NEO compensation plans and awards, and the full Board reviews and approves the corporate performance goals.

Most officers, including the NEOs and officers serving Peoples in support roles, such as accounting, loan operations and deposit operations, participate in the annual cash and long-term equity-based incentive program. Annual cash incentives, as well as equity-based incentives under the incentive program, are payable only when specific pre-determined performance goals are met. All participants in the incentive program have some portion of both their annual and long-term incentive awards dependent on the selected corporate performance criteria. In addition, the potential incentives payable to senior officers having only compliance, risk, credit quality and internal control roles are tied to corporate goals under the incentive program with only a 25% weighting. The remainder of their potential incentives is determined based upon the level of achievement of individual goals tied to their specific job functions. The Compensation Committee ultimately approves all incentive compensation paid to the NEOs.

In addition to the incentive program, we have (i) compensation plans for producers, including insurance agents and financial advisors, which include variable pay components (commission based on the sales of products underwritten or offered by independent third parties); (ii) compensation plans for home loan originators which include variable cash compensation components tied to the origination of one-to-four family real estate loans, the majority of which are sold into the secondary market; and (iii) other miscellaneous individual plans which are informal agreements that allow certain employees to earn amounts of cash incentive compensation without encouraging the employees to take unnecessary or excessive risk. The foregoing roles inherently do not have the opportunity for excessive levels of risk, either individually or in the aggregate.

The Compensation Committee believes that the elements of the incentive program and the other compensation plans, alone and/or combined with the systems of controls in place, such as separation of the valuation, authorization and payment of incentive compensation, do not encourage unnecessary or excessive risk-taking and do not encourage the manipulation of reported earnings to enhance the compensation of any employee or group of employees.

Further, in light of the significant level of oversight and controls surrounding incentive programs and the significant amounts that would be required to materially impact Peoples' reported earnings, the Compensation Committee believes that, upon evaluation of the incentive opportunities for employees, including the NEOs, any elements of the incentive program and other compensation and individual plans that have the potential to encourage the manipulation of reported earnings to enhance the compensation of any individual employee are appropriately mitigated.

S. Craig Beam (Chair), W. Glenn Hogan, Brooke W. James, Kevin R. Reeves, Carol A. Schneeberger, Frances A. Skinner, and Michael N. Vittorio.

Refer to the discussion under the caption "**2025 Executive Compensation Components - Cash and Equity-Based Incentive Program**" of "**EXECUTIVE COMPENSATION: COMPENSATION DISCUSSION AND ANALYSIS**" beginning on page [51](#ie4918d8a029e40428ac76ab486476da9_256) of this Proxy Statement, for additional information regarding grants of equity-based awards.

(3)Reflects the aggregate number of restricted common shares (if any) granted through the 2024 incentive program based upon corporate and individual performance for the 2024 fiscal year, which were approved on January 22, 2025 and granted under the 2006 Plan on February 11, 2025. The fair value of the equity-based incentive awards earned was converted into the number of restricted common shares shown, using the closing price of Peoples common shares on the grant date. All restricted common shares will vest on February 11, 2028 if the NEO remains employed by Peoples or has met Peoples' definition of retirement or disability on that date. The vesting is also subject to the requirements that Peoples has maintained a well capitalized status under applicable regulatory standards and reported net income for each of the fiscal years comprising the vesting period. The NEO has the right to vote the common shares underlying the restricted common shares and is entitled to receive dividends paid with respect to the underlying common shares at the same level as paid to other shareholders of Peoples; however, the dividends will be subject to the same restrictions on transfer as the restricted common shares with respect to which they were paid or issued and will accrue until paid at vesting.

**OUTSTANDING EQUITY AWARDS AT FISCAL YEAR-END 2025**

The following table provides information relating to the outstanding equity awards held by the NEOs at the end of the 2025 fiscal year. There were no options or SARs held by the NEOs at the end of the 2025 fiscal year. All stock awards listed in the table reflect restricted common shares of Peoples granted under the 2006 Plan. Each individual grant of restricted common shares is shown on a separate line for each NEO. The market value of the stock awards is based on the closing price of Peoples common shares as reported on The Nasdaq Global Select Market<sup>®</sup> on December 31, 2025 (the last trading day during the 2025 fiscal year), which was $30.03.

**NON-QUALIFIED DEFERRED COMPENSATION FOR 2025**

The following table provides information regarding the NEOs' participation in the NQDC Plan for 2025. Participants in the NQDC Plan may elect to defer base salary, other cash payments including non-equity incentive payments, over-time and bonus cash payments (excluding sign-on bonuses), commissions, referral fees, draws against commission in excess of commission earned, holiday, vacation, paid-time-off payments and payments made under the short-term disability plan. Generally, a participant must submit a deferral election by December 31 of the year before services are to be performed. The deferred compensation, if any, is credited to a bookkeeping account maintained on behalf of the participant. The participant is fully vested in the bookkeeping account which will be credited with earnings and losses based on the performance of the deemed investment selections made by the participant for the bookkeeping account. The Compensation Committee determines the deemed investments with which participants may direct that their bookkeeping accounts be credited.

Peoples may make discretionary contributions to participants' bookkeeping accounts in such amount that would have been made pursuant to Peoples' 401(k) Plan as matching contributions as if all amounts selected to be deferred by participants under the NQDC Plan had been deferred under Peoples' 401(k) Plan. Any such discretionary contributions will be credited to the participants' bookkeeping accounts each pay period with respect to compensation deferred in that pay period and will vest in accordance with the vesting schedule under Peoples' 401(k) Plan, provided that the discretionary contribution amounts will become fully vested in the event of a participant's retirement (as defined in the NQDC Plan) or death, voluntary termination or involuntary termination without cause and will be forfeited if a participant is terminated for cause.

For additional information regarding the NQDC Plan, refer to the section captioned "**Retirement and Other Benefits - Nonqualified Deferred Compensation Plan**" of "**EXECUTIVE COMPENSATION: COMPENSATION DISCUSSION AND ANALYSIS**" beginning on page [57](#ie4918d8a029e40428ac76ab486476da9_259) of this Proxy Statement.

(5)Cumulative TSR is calculated by dividing the sum of the cumulative amount of dividends for the measurement period (determined in accordance with Item 402(v) of SEC Regulation S-K), assuming dividend reinvestment, and the difference between Peoples' common share price at the end and the beginning of the measurement period by Peoples' common share price at the beginning of the measurement period.

**Financial Performance Measures**

As described in greater detail in "**EXECUTIVE COMPENSATION: COMPENSATION DISCUSSION AND ANALYSIS**" beginning on page [41](#ie4918d8a029e40428ac76ab486476da9_202) of this Proxy Statement, Peoples' executive compensation programs are designed to incentivize sound and fundamental growth and profitability, which will lead to improved returns to shareholders. We take into account both the absolute performance of Peoples, as well as the relative improvement in the performance of Peoples during any given time period. The most important financial measures used by Peoples to link executive compensation actually paid to the NEOs, for the most recently completed fiscal year, to Peoples' performance are as follows:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Pre-Tax/Pre-Provision Return on Average Assets ("PTPP ROAA")

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Efficiency Ratio

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Pre-Tax/Pre-Provision Diluted Earnings Per Common Share ("PTPP EPS")

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Net Charge-Offs as a Percentage of Average Total Loans

**Analysis of Information Presented in the Pay Versus Performance Table**

In accordance with Item 402(v) of Regulation S-K, Peoples is providing the following descriptions of the relationships between information presented in the "Pay Versus Performance Table."

***Compensation Actually Paid and Cumulative TSR***

As demonstrated by the following graph, the compensation actually paid to our CEO and the average compensation actually paid to the NEOs as a group (excluding our CEO) was directionally aligned with Peoples' cumulative TSR between 2022 and 2023, between 2023 and 2024, and between 2024 and 2025, but was not directionally aligned between 2021 and 2022. The alignment in the years presented was due in part to the fact that a meaningful portion of compensation actually paid to our CEO and to the other NEOs was comprised of equity awards. Peoples' cumulative TSR in those years had the effect of either increasing or decreasing the relative value of the equity award component of compensation actually paid for each of those years. The lack of alignment between 2021 and 2022 was due to the fact that Peoples' cumulative TSR in 2022 did not reflect the strong improvement in the financial performance measures in 2022 that drove executive compensation that year, a trend similarly impacting the stock prices of the Peer Group and other financial institutions. Although the value of the equity awards component of compensation actually paid for 2022 declined as a result of the lower cumulative TSR, the reduction was more than offset by the increased amount of compensation driven by the improved financial performance measures listed above.

***Compensation Actually Paid and Net Income***

As demonstrated by the following graph, the amount of compensation actually paid to our CEO and the average amount of compensation actually paid to the NEOs as a group (excluding our CEO) was directionally aligned with Peoples' net income for three of the five years presented. There was not alignment in 2024 and 2025, which was due in part to the CEO transition that occurred in 2024. While Peoples does not use net income as a specific performance measure in its executive compensation program, the measure of net income is correlated with the measures of PTPP EPS, PTPP ROAA and the efficiency ratio, which Peoples does use in setting performance goals for executive compensation.

![Compensation Actually Paid and Net Income.jpg](pebo-20260306_g15.jpg)

***Compensation Actually Paid and Pre-Tax/Pre-Provision Diluted Earnings Per Common Share***

As demonstrated by the following graph, the amount of compensation actually paid to our CEO and the average amount of compensation actually paid to the other NEOs (excluding our CEO) was directionally aligned with Peoples' PTPP EPS in 2022, 2023, and 2025. There was not alignment in 2024, which was due in part to the CEO transition that year.

***Cumulative TSR of Peoples and Cumulative TSR of the Peer Group***

As demonstrated by the following graph, Peoples cumulative TSR in each of 2021, 2022, 2024, and 2025 fell short of that of the peer group used for benchmarking executive compensation, and Peoples' cumulative TSR in 2023 greatly exceeded that of the peer group.

![Company TSR vs Peer Group TSR.jpg](pebo-20260306_g17.jpg)

**OTHER POTENTIAL POST-EMPLOYMENT PAYMENTS**

The amount of compensation payable to each NEO upon voluntary termination, early retirement, normal retirement, involuntary not-for-cause termination, for cause termination, termination following a change in control of Peoples and termination in the event of the death or disability of the NEO is described below.

An NEO participating in the NQDC Plan is fully vested at all times in the portion of the participant's bookkeeping account attributable to compensation deferred by the participant and any deemed earnings on such amounts. The portion of the participant's bookkeeping account attributable to discretionary contributions from Peoples and any deemed earnings on the investment of the discretionary contributions will become fully vested in the event of the participant's retirement (as defined in the NQDC Plan), death, voluntary termination or involuntary termination without cause and will be forfeited if the participant is terminated for cause.

**Payments Made Upon Termination of Employment**

Regardless of the manner in which an NEO's employment terminates, including termination for cause with the exception noted below, the NEO is entitled to receive amounts earned during the NEO's term of employment. These amounts are not included in the table below. Such amounts would include:

• all vested equity-based awards earned through the long-term equity-based incentive compensation programs;

• the balance of the NEO's account in Peoples' 401(k) Plan;

• the balance credited to the NEO's bookkeeping account in the NQDC Plan, if the NEO is a participant in the NQDC Plan, in the event employment terminates other than for cause (this amount as of December 31, 2025 is included in the table in the section captioned "**NON-QUALIFIED DEFERRED COMPENSATION FOR 2025**" beginning on page [68](#ie4918d8a029e40428ac76ab486476da9_319) of this Proxy Statement and shown in the "Aggregate Balance at Last Fiscal Year-End" column); and

• pay out of unused paid time off, commensurate with the length of service in the current calendar year, except in the event of voluntary termination or termination for cause.

***Payments Made Upon Retirement***

In the event of the retirement of an NEO (whether normal or early), in addition to the items identified above, unvested equity awards under the 2006 Equity Plan subject to performance goals would vest and become transferable to the NEO upon attainment of the performance goals specific to the respective grants, and unvested grants of time-based restricted common shares would be forfeited.

For purposes of unvested equity awards under the 2006 Equity Plan that are subject to performance goals, retirement may occur: (i) in the case of awards made prior to November 20, 2024, at the age of 62 if the NEO has at least five years of service; and (ii) in the case of awards made on or after November 20, 2024, either (a) at the age of 55 if the NEO has at least seven years of service; if the retirement occurs as of a date mutually agreed upon between Peoples and the NEO (provided that such date is at least 12 months for the CEO or six months for the other NEO's after the date the NEO provides written notice to Peoples of the NEO's proposed retirement); if the NEO agrees to enter into enforceable non-compete covenants for a period of at least 12 months after the retirement date; and if the NEO cooperates to Peoples' reasonable satisfaction with the transition of the NEO's duties; or (b) at the age 62 if the NEO has at least five years of service.

***Payments Made Upon Death or Disability***

In the event of death or disability of an NEO, in addition to the benefits listed under the headings "Payments Made Upon Termination of Employment" and "Payments Made Upon Retirement" above, the NEO would also receive benefits under Peoples' disability plan or the NEO's beneficiary would also receive payments under the Peoples Bancorp Group Term Life Insurance Plan and under the BOLI benefit, as applicable.

In the event of death of an NEO: (i) in the case of unvested equity awards subject to performance goals made prior to November 20, 2024, a portion of the unvested restricted common shares, determined by multiplying the number of such restricted common shares by a fraction, the numerator of which is the number of whole months elapsed during the performance period prior to the NEO's death, and the denominator of which is the number of months in the performance period, will immediately vest and the remainder would be forfeited; (ii) in the case of unvested equity awards subject to performance goals made on or after November 20, 2024, all of the unvested restricted common shares under the 2006 Equity Plan will immediately vest.

In the event of death or disability of an NEO, any unvested time-based restricted common shares under the 2006 Equity Plan will immediately vest. In the event of disability of an NEO, unvested equity awards subject to performance goals under the 2006 Equity Plan would vest and become transferable upon attainment of the performance goals specific to the respective grants.

***Payments Made Upon a Change in Control***

In the event of a change in control where the surviving entity (the "acquiror") is not Peoples and the acquiror does not assume or substitute equivalent awards for outstanding unvested equity awards under the 2006 Equity Plan, all such outstanding unvested equity awards would become immediately and fully vested. Additionally, the Board or its designee may, in its sole discretion, provide for a cash payment to be made to each participant for the outstanding unvested equity award upon the consummation of the change in control, determined on the basis of the fair market value that would be received in such change in control by the holders of Peoples common shares underlying such awards.

In the event of a change in control where Peoples is the surviving entity, or the acquiror assumes the outstanding unvested equity awards or substitutes equivalent equity awards relating to the securities of such acquiror or its affiliates, then all such awards or substitutes would remain outstanding and be governed by their respective terms and the provisions of the 2006 Equity Plan. In such a change in control scenario:

• If an NEO is terminated without cause or terminates his or her employment with Peoples and our subsidiaries and/or the acquiror for good reason within 24 months following the change in control, then all of the NEO's outstanding unvested equity awards would become immediately and fully vested; and

**Peoples Bancorp Inc.**

• If an NEO's employment is terminated for cause within 24 months following such change in control, then any unvested equity awards would be forfeited, and all rights under such awards would terminate immediately.

We have entered into change in control agreements with each of the NEOs. Under the change in control agreements, a change in control occurs when one or more of the following events take place:

• a "person" or "group" (as defined in Section 409A) acquires ownership of shares of Peoples that, together with shares held by such person or group, constitutes more than 50% of the total fair market value or total voting power of the shares of Peoples;

• any person or group acquires (or has acquired during the 12-month period ending on the date of the most recent acquisition by such person or group) ownership of shares of Peoples possessing 35% or more of the total voting power of the shares of Peoples;

• a majority of the members of the Board is replaced during any 12-month period by directors whose appointment or election is not endorsed by a majority of the members of the Board prior to the date that such appointments or elections are made; or

• any person or group acquires (or has acquired), during the 12-month period ending on the date of the most recent acquisition by such person or group, assets from Peoples that have a total gross fair market value equal to or more than 40% of the total gross fair market value of all of the assets of Peoples immediately prior to such acquisition or acquisitions.

Generally, the change in control agreements provide for severance compensation to an NEO if the NEO's employment is terminated by Peoples or its successor for any reason other than cause (defined as gross negligence or gross neglect of duties; commission of a felony or a gross misdemeanor involving moral turpitude in connection with the NEO's employment with Peoples; fraud, disloyalty, dishonesty or willful violation of any law or significant policy of Peoples committed in connection with the NEO's employment with Peoples; or issuance of an order by the banking regulators of Peoples for removal of the NEO) within six months prior to or 24 months after a defined change in control occurs. In addition, compensation will be paid if the NEO voluntarily terminates employment during the same periods because of: (i) the assignment to the NEO of any material duties or responsibilities inconsistent with the NEO's position(s), or a change in the NEO's reporting responsibilities, title(s), or office(s), or any removal of the NEO from or any failure to re-elect the NEO to any such position(s), except in connection with the NEO's termination of employment for cause, disability, retirement, or as a result of the NEO's death; (ii) a reduction in the NEO's base salary; (iii) the taking of any action by Peoples or its successor which would adversely affect the NEO's participation in or materially reduce the NEO's benefits under any benefit plans; (iv) any failure of Peoples to obtain the assumption of the agreement by any successor; or (v) geographic relocation of the NEO to an office location more than 50 miles from the NEO's then current location without the NEO's consent or without reimbursement of reasonable moving expenses incurred by the NEO relating to a change of the NEO's principal residence in connection with relocation.

For each of the NEOs, the base annual compensation for purposes of his or her respective change in control agreement is the sum of (a) his or her annualized monthly base salary, payable by Peoples for the calendar year in which the date of the change in control occurs, plus (b) the average annualized awards payable to him or her under Peoples' annual cash incentive program with respect to the most recent three calendar years ended before the date of the change in control, subject to certain adjustments in the event that Section 280G of the Internal Revenue Code is triggered. If an NEO has worked for Peoples for less than three years, the average annualized awards payable to him or her under Peoples' annual cash incentive program would be calculated in accordance with the provisions of the NEO's change in control agreement.

Under the change in control agreements, severance provisions include: (i) a lump-sum cash payment of 2.00 times base annual compensation for Ms. Bailey, Mr. Donlon, Mr. Kirkham and Mr. Wyatt, and 2.99 times base annual compensation for Mr. Wilcox, in each case payable within 30 days following the NEO's termination date with such payment delayed until the first business day of the seventh month following the NEO's termination date if the NEO is a "specified employee" for purposes of Section 409A on NEO's termination date; (ii) continuing participation in life, medical, and dental insurance for 12 months (36 months in the case of Mr. Wilcox) in substantially the same form and expense to the NEO as that received on the date of termination; (iii) the NEO agreeing not to disclose to others any confidential information; and (iv) the NEO entering into a non-compete agreement for 12 months (15 months for Mr. Wilcox) immediately following the date of termination. The non-compete provision prohibits the NEO from directly or

indirectly engaging in any business in which Peoples directly or indirectly engages during the term of the NEO's change in control agreement, within the geographic market as delineated on the NEO's termination date in the Community Reinvestment Act Statement of Peoples Bank.

The following table summarizes payments which would have been made and benefits that would have been provided to each of the NEOs with respect to previously unvested cash-based awards and unvested equity-based awards as well as under the terms of such NEO's change in control agreement if a termination event had occurred on December 31, 2025. Actual amounts to be paid out or provided can only be determined at the time of an NEO's actual separation from service with Peoples. Please refer to the discussion under the headings "**Payments Made Upon Termination of Employment**," "***Payments Made Upon Retirement***" and "***Payments Made Upon Death or Disability***" for the other payments that would have been made and benefits that would have been provided to the NEOs identified in the following table if such a termination event had occurred on December 31, 2025.

(2)A portion of the unvested equity awards subject to performance goals, determined by multiplying the number of common shares underlying such restricted common shares by a fraction, the numerator of which is the number of the whole months elapsed during the performance period prior to the NEO's death, and the denominator of which is the number of months in the performance period, will immediately vest upon the NEO's death for awards made prior to November 20, 2024.

equity awards subject to performance goals made after November 20, 2024, and any unvested time-based equity awards will immediately vest upon the NEOs death.

(3)Under the terms of their respective change in control agreements, the NEOs continue to participate in life, medical and dental insurance during the term of their respective non-compete agreements (36 months for Mr. Wilcox, 12 months for the other NEOs).

(4)In the event any payments to the NEOs would exceed the amount that could be received without the imposition of an excise tax under Section 4999 of the Internal Revenue Code, the payments would be reduced to the extent necessary to ensure that such payments would be limited to the greater of (i) the dollar amount which could be paid to the NEO without triggering an excise tax under Section 4999 of the Internal Revenue Code, or (ii) the greatest after-tax amount payable to the NEO after taking into account any excise tax imposed under Section 4999 of the Internal Revenue Code on the total payments.

Mr. Wilcox, Ms. Bailey, Mr. Donlon, and Mr. Kirkham would have been the NEOs to whom payments would have triggered an excise tax under Section 4999 of the Internal Revenue Code in the hypothetical situation described in the preceding paragraph. In this case, option (i) as described in the preceding paragraph would have resulted in the greatest after-tax amount and, as such, the payments would have been reduced in order to avoid triggering the excise tax. The amount shown is the amount by which the payments would have been reduced.

**COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION**

Each of S. Craig Beam, W. Glenn Hogan, Brooke W. James, Carol A. Schneeberger, Frances A. Skinner, Kevin Reeves and Michael N. Vittorio served as a member of the Compensation Committee of the Board throughout the 2025 fiscal year, and each continues to so serve. None of these individuals has been an officer or an employee of Peoples or any of our subsidiaries, with the exception of Ms. Schneeberger, who retired from Peoples on March 31, 2020. Each of the current members of the Compensation Committee qualified as an independent director under the applicable Nasdaq Rules and each of the current members of the Compensation Committee continue to so qualify. During the 2025 fiscal year, Peoples Bank entered into banking transactions (including deposit, trust or other banking services and/or loans and loan commitments) with certain members of the Compensation Committee, with members of their respective immediate families and with corporations and organizations as to which Compensation Committee members serve as executive officers or beneficially own more than 10% of the equity securities. These transactions were in compliance with applicable federal and state laws and regulations. It is expected that similar banking transactions will be entered into in the future. Any loans to these persons (i) were made in the ordinary course of business, (ii) were made on substantially the same terms, including interest rates charged and collateral required, as those prevailing at the time for comparable loans with persons not related to Peoples or Peoples Bank, and (iii) did not involve more than the normal risk of collectability or present other unfavorable features to Peoples or Peoples Bank. In addition, as of the date of this Proxy Statement, none of the loans described in this paragraph have been or would be disclosed as past due, nonaccrual, or modified for borrowers facing financial difficulty in Peoples' consolidated financial statements. During the 2025 fiscal year, no executive officer of Peoples served on the board of directors or compensation committee (or other committee serving an equivalent function) of any other entity that had one or more executive officers serving on the Board or on the Compensation Committee of Peoples.

**AUDIT COMMITTEE REPORT FOR THE FISCAL YEAR ENDED** 

**DECEMBER 31, 2025**

Management has represented to the Audit Committee that Peoples' audited consolidated financial statements as of and for the fiscal year ended December 31, 2025, were prepared in accordance with US GAAP, and the Audit Committee has reviewed and discussed the audited consolidated financial statements with management.

In addition, the Audit Committee has discussed and reviewed with Ernst & Young LLP ("EY"), Peoples' independent registered public accounting firm, all communications and other matters required to be discussed by auditing standards generally accepted in the United States, including those described in Public Company Accounting Oversight Board (United States) (the "PCAOB") Auditing Standard No. 1301 (Communications with Audit Committee) and other applicable PCAOB requirements and by SEC rules, as well as significant current accounting developments and issues. The Audit Committee has also reviewed and discussed the audited consolidated financial statements as of and for the fiscal year ended December 31, 2025 with EY.

**Peoples Bancorp Inc.**

The Audit Committee has received from EY the written disclosures and the letter required by applicable requirements of the PCAOB regarding EY's communications with the Audit Committee concerning independence, and has discussed with EY the independence of EY. The Audit Committee has discussed with EY any relationships with or services to Peoples or Peoples' subsidiaries that may impact EY's independence and objectivity, including the non-audit services rendered by EY, and the Audit Committee has satisfied itself as to EY's independence.

As disclosed in the "Report of Management's Assessment of Internal Control Over Financial Reporting" included in Peoples' Annual Report on Form 10-K for the fiscal year ended December 31, 2025, management of Peoples evaluated the effectiveness of Peoples' internal control over financial reporting and concluded that Peoples' internal control over financial reporting was effective at a reasonable assurance level as of December 31, 2025.

Based on the Audit Committee's reviews and discussions with management and EY, and the Audit Committee's review of the report of EY to the Audit Committee, the Audit Committee recommended to the full Board that Peoples' audited consolidated financial statements be included in Peoples' Annual Report on Form 10-K for the fiscal year ended December 31, 2025 for filing with the SEC.

**Submitted by the Audit Committee of the Board:**

David F. Dierker (Chair), W. Glenn Hogan, Carol A. Schneeberger, Frances A. Skinner, Dwight E. Smith, and Michael N. Vittorio.

**INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM**

On February 25, 2025, the Audit Committee appointed EY as Peoples' independent registered public accounting firm for the fiscal year ended December 31, 2025. EY has served as Peoples' independent auditors/independent registered public accounting firm since 1995.

**Fees**

Fees for services rendered by EY for each of the 2025 fiscal year and the 2024 fiscal year were:

---

| | | |
|:---|:---|:---|
| | **2025** | **2024** |
| Audit Fees (1) | $1501279 | $1420265 |
| Audit-Related Fees (2) | $50000 | $50000 |
| Tax Fees (3) | $65000 | $74481 |
| All Other Fees (4) | $222359 | $157344 |
| **Total** | **$1838638** | **$1702090** |

---

(1)Audit Fees pertain to professional services rendered in connection with the integrated audit of Peoples' annual consolidated financial statements and internal control over financial reporting, reviews of the consolidated financial statements included in Peoples' Quarterly Reports on Form 10-Q.

(2)Audit-Related Fees pertain to professional services rendered in connection with review of Peoples' compliance with Housing and Urban Development ("HUD") procedures.

(3)Tax Fees pertain to permissible tax services rendered for tax planning and advice, tax compliance and assistance with tax audits and appeals.

(4)All Other Fees pertain to federal and state income tax preparation services for trust accounts with Peoples Bank. Peoples Bank offsets the expenses for these services by charging each trust account with a tax preparation fee.

EY did not render any other services to Peoples or any of our subsidiaries during the 2025 fiscal year or the 2024 fiscal year. All of the services described under "Audit Fees," "Audit-Related Fees," "Tax Fees" and "All Other Fees" above were pre-approved by the Audit Committee.

**Pre-Approval Policy**

The Audit Committee has adopted, and the full Board has ratified, an Audit and Non-Audit Services Pre-Approval Policy (the "Pre-Approval Policy"), which sets forth the procedures and conditions pursuant to which services proposed to be performed by the independent registered public accounting firm may be pre-approved. Proposed

**Peoples Bancorp Inc.**

services may either be pre-approved without consideration of specific case-by-case services by the Audit Committee ("general pre-approval"), or be subject to the requirement that the specific pre-approval of the Audit Committee be obtained ("specific pre-approval"). Appendices to the Pre-Approval Policy describe the Audit, Audit-Related, Tax and All Other services that have the general pre-approval of the Audit Committee. The term of any general pre-approval is 12 months from the date of pre-approval, unless the Audit Committee states otherwise. The Audit Committee annually reviews and pre-approves the services that may be provided by the independent registered public accounting firm without obtaining specific pre-approval from the Audit Committee. The Audit Committee will add to or remove from the list of general pre-approved services from time to time, based on subsequent reviews and determinations.

The Pre-Approval Policy does not delegate to management the Audit Committee's responsibilities to pre-approve services performed by the independent registered public accounting firm. The Audit Committee may, however, delegate pre-approval authority to one or more of its members. The member(s) to whom such authority is delegated must report, for informational purposes only, any pre-approval decisions to the Audit Committee at the Audit Committee's next scheduled meeting. The Audit Committee has delegated both types of pre-approval authority to the Chair of the Audit Committee.

All requests or applications for services to be provided by the independent registered public accounting firm are to be submitted to the Chief Financial Officer of Peoples, and must include a detailed description of the services to be rendered. The Chief Financial Officer and the independent registered public accounting firm must determine jointly whether, in their view, the request or application is consistent with the SEC's and the PCAOB's rules on auditor independence and is an appropriate service. If so, the Chief Financial Officer will request specific pre-approval from the Audit Committee (or its designee) as appropriate. Any proposed services exceeding pre-approved cost levels or budgeted amounts will also require specific pre-approval by the Audit Committee.

The Audit Committee has designated the Director of Internal Audit of Peoples to monitor the performance of all services provided by the independent registered public accounting firm and to determine whether such services are in compliance with the Pre-Approval Policy. The Director of Internal Audit reports to the Audit Committee on a periodic basis as to the results of such monitoring. Both the Director of Internal Audit and the management of Peoples are to immediately report to the Chair of the Audit Committee any breach of the Pre-Approval Policy that comes to the attention of the Director of Internal Audit or any member of Peoples' management.

**PROPOSAL NUMBER 3: RATIFICATION OF APPOINTMENT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM**

The Audit Committee has appointed EY to serve as Peoples' independent registered public accounting firm for the fiscal year ending December 31, 2026, and recommends that Peoples' shareholders vote for the ratification of that appointment. EY audited Peoples' consolidated financial statements as of and for the fiscal year ended December 31, 2025, and the effectiveness of Peoples' internal control over financial reporting as of December 31, 2025. Representatives of EY are expected to be present at the virtual Annual Meeting and will be given the opportunity to make a statement if they so desire and will be available to respond to appropriate questions.

The appointment of Peoples' independent registered public accounting firm is made annually by the Audit Committee. Peoples has determined to submit the appointment of the independent registered public accounting firm to the shareholders for ratification because of such firm's role in reviewing the quality and integrity of Peoples' consolidated financial statements and internal control over financial reporting. Before appointing EY, the Audit Committee carefully considered that firm's qualifications as Peoples' independent registered public accounting firm and the audit scope. The Audit Committee evaluates EY's qualifications, performance and independence in accordance with regulatory requirements and guidelines. As part of this evaluation, the Audit Committee considered various factors, including EY's capabilities and expertise; the recent performance of EY on Peoples' audit; the assessment by Peoples' management of EY's performance; external data on audit quality, including results of recent PCAOB reports on EY and its peers; EY's independence; the terms of the audit engagement; and the quality and candor of EY's communications to the Audit Committee.

**Recommendation and Vote**

|:---|:---|
| **THE AUDIT COMMITTEE AND THE FULL BOARD UNANIMOUSLY RECOMMEND THAT PEOPLES' SHAREHOLDERS VOTE "FOR" THE RATIFICATION OF THE APPOINTMENT OF EY.** | ![Image_11.jpg](pebo-20260306_g11.jpg) |

---

The affirmative vote of a majority of the common shares represented at the Annual Meeting, in person or by proxy, and entitled to vote on the proposal, is required to ratify the appointment of EY as Peoples' independent registered public accounting firm for the fiscal year ending December 31, 2026. The effect of an abstention is the same as a vote "**AGAINST**." Even if the appointment of EY is ratified by the shareholders, the Audit Committee, in its discretion, could decide to terminate the engagement of EY and to engage another firm if the Audit Committee determines such action is necessary or desirable. If the appointment of EY is not ratified, the Audit Committee will reconsider (but may decide to maintain) the appointment.

**HOUSEHOLDING OF ANNUAL MEETING MATERIALS**

The SEC has implemented rules regarding the delivery of proxy materials to households. This method of delivery, often referred to as "householding," would permit Peoples to send: (a) a single annual report to shareholders and/or a single Proxy Statement or (b) a single notice of internet availability of proxy materials, as applicable, to any household at which two or more different registered shareholders reside if Peoples reasonably believes such shareholders are members of the same family or otherwise share the same address or that one shareholder has multiple accounts. In each case, the registered shareholder(s) would be required to consent to the householding process in accordance with applicable SEC rules, and would be able at any time to request that Peoples promptly deliver to such shareholder(s) a separate copy of the proxy materials subject to householding. The householding procedure is intended to reduce the volume of duplicate information shareholders receive and would reduce Peoples' expenses. Peoples does not currently practice householding, but may institute householding in the future and will notify registered shareholders affected by householding at that time.

Notwithstanding the foregoing, registered shareholders sharing an address who currently receive multiple copies of proxy materials may request delivery of a single copy of Peoples' annual reports to shareholders, Proxy Statements and/or notices of internet availability of proxy materials, as applicable, by contacting the Corporate Secretary of Peoples at Peoples Bancorp Inc., 138 Putnam Street, P.O. Box 738, Marietta, Ohio 45750-0738, Attention: Corporate Secretary.

Many brokers, financial institutions and other holders of record have instituted householding. If your family has one or more "street name" accounts under which you beneficially own common shares of Peoples, you may have received householding information from your broker, financial institution or other nominee in the past. Please contact the holder of record directly if you have questions, require additional copies of this Proxy Statement or Peoples' 2025 Annual Report or the notice of internet availability of proxy materials provided by the holder of record or wish to revoke your decision to household and thereby receive multiple copies of Peoples' proxy materials (including annual reports to shareholders) or notice of internet availability of proxy materials, as applicable. You should also contact the holder of record if you wish to institute householding.

**OTHER MATTERS**

As of the date of this Proxy Statement, the Board knows of no matter that will be presented for action by Peoples' shareholders at the Annual Meeting other than those matters discussed in this Proxy Statement. However, if any other matter requiring a vote of the shareholders is properly presented at the Annual Meeting, the individuals acting under the proxies solicited by the Board will vote and act according to their best judgment in light of the conditions then prevailing, to the extent permitted under applicable law.
