Change in Control Agreement dated August 1, 2024, among Tyler Wilcox and Peoples Bancorp Inc

This CHANGE IN CONTROL AGREEMENT is adopted this 1st day of August, 2024 by and between PEOPLES BANCORP INC., a financial holding company, located in Marietta, Ohio (the “Company”), and Tyler Wilcox (the “Executive”), an executive of the Company or one of its Subsidiaries.

The Board of Directors of the Company (the “Board”) has determined that it is in the best interests of the Company to retain the Executive’s services and to reinforce and encourage the continued attention and dedication of the Executive to the Executive’s assigned duties, without distraction in potentially disturbing circumstances arising from the possibility of a change in control of the Company or the assertion of claims and actions against the Executive.

Whenever used in this Agreement, the following words and phrases shall have the meanings specified:

1.1 “Agreement” means this Peoples Bancorp Inc. Change in Control Agreement, as it may be amended from time to time.

1.2 “Base Annual Compensation” means the sum of (a) the Executive’s annualized monthly base salary, payable by the Company or one of its Subsidiaries, for the calendar year in which the date of the Change in Control occurs (the “Base Salary Component”), plus (b) the average annualized awards payable to the Executive under the Company’s annual cash incentive program with respect to the most recent three calendar years ended before the date of the Change in Control (the “Cash Incentive Component”). Notwithstanding the foregoing, in the event that the Executive became an “employee” (as that term is defined in the Peoples Bancorp Inc. Third Amended and Restated 2006 Equity Plan or any successor plan) of the Company or one of its Subsidiaries either during the same calendar year as the date of the Change in Control or during any of the most recent three calendar years ended before the date of the Change in Control, for purposes of determining the “Cash Incentive Component” to be used in the calculation of “Base Annual Compensation,” with respect to each of the most recent three calendar years ended before the date of the Change in Control in which either (x) the Executive was not eligible to receive an award under the Company’s annual cash incentive program because the Executive was not employed by the Company or any of its Subsidiaries on or before the last day the Executive was required to be employed in order to be eligible to receive an award for such calendar year or (y) the Executive was eligible to receive only a partial or pro rata award under the Company’s annual cash incentive program because the Executive was employed by the Company or one of its Subsidiaries for less than the full calendar year, the greater of: (A) the amount of the actual award payable to the Executive under the Company’s annual cash incentive program with respect to the calendar year described in clause (x) or clause (y) of this Section 1.2

or (B) the amount of the Executive’s target payout potential under the Company’s annual cash incentive program in which the Executive is participating or would have been eligible to participate during the calendar year in which the Change in Control occurs, shall be used for each calendar year described in clause (x) or clause (y) of this Section 1.2 when calculating the average annualized awards under the “Cash Incentive Component” instead of the amount of the actual award, if any, payable to the Executive under the Company’s annual cash incentive program for such calendar year.

1.3 “Cause” means

(a) Gross negligence or gross neglect of duties; or

(b) Commission of a felony or of a gross misdemeanor involving moral turpitude in connection with the Executive’s employment with the Company or a Subsidiary; or

(c) Fraud, disloyalty, dishonesty or willful violation of any law or significant Company or Subsidiary policy committed in connection with the Executive’s employment; or

(d) Issuance of an order for removal of the Executive by the bank or other governmental regulator(s) of the Company or any of its Subsidiaries.

1.4 “Change in Control” shall occur on the earliest date that

(b) any person or group acquires (or has acquired during the twelve (12) month period ending on the date of the most recent acquisition by such person or group) ownership of stock of the Company possessing thirty-five percent (35%) or more of the total voting power of the stock of the Company;

(c) a majority of the members of the Board is replaced during any twelve (12) month period by directors whose appointment or election is not endorsed by a majority of the members of the Company’s Board prior to the date that such appointments or elections are made; or

Notwithstanding the foregoing, the definition of “Change in Control” shall be interpreted consistent with the definition of “change in control event” under Section 409A of the Code.

1.5 “Code” means the Internal Revenue Code of 1986, as amended.

1.6 “Disability” means the Executive’s suffering a sickness, accident or injury which has been determined by the insurance carrier of any individual or group disability insurance policy covering the Executive, or by the Social Security Administration, to be a disability rendering the Executive totally and permanently disabled.

The Executive shall not at any time, either during or subsequent to the term of this Agreement, disclose to others, use, copy or permit to be copied, except as directed by law or in pursuance of the Executive’s duties for or on behalf of the Company, its Subsidiaries, or their respective successors, assigns or nominees, any Confidential Information of the Company or any Subsidiary (regardless of whether developed by the Executive), without the prior written consent of the Company. The term “Confidential Information” with respect to any person means any secret or confidential information or know-how and shall include, but shall not be limited to, the plans, customers, costs, prices, uses, and applications of products and services, results of investigations, studies owned or used by such person, and all products, processes, compositions, computer programs, and servicing, marketing or operational methods and techniques at any time used, developed, investigated, made or sold by such person, before or during the term of this Agreement, that are not readily available to the public or that are maintained as confidential by such person.

3.2 No Competition. If within the six (6) months prior to or the twenty-four (24) months following a Change in Control of the Company, the Executive shall have an involuntary Termination of Employment by the Company or the relevant Subsidiary other than for Cause, or shall have a voluntary Termination of Employment for Good Reason, then and for a period of fifteen (15) months immediately following the Termination Date, the Executive shall not directly or indirectly engage in the business of banking, or any other business in which the Company or any of its Subsidiaries directly or indirectly engage during the term of this Agreement; provided, however, that this restriction shall apply only to the geographic market of the Company and its Subsidiaries as delineated on the Termination Date in the Community Reinvestment Act Statement of Peoples Bank.

listed on any national or regional securities exchange or have been registered under Section 12(g) of the Securities Exchange Act of 1934 and (b) the Executive does not beneficially own (as defined Rule 13d-3 promulgated under the Securities Exchange Act of 1934) in excess of one percent of the outstanding capital stock of such enterprise.

3.3 Delivery of Documents Upon Termination. The Executive shall deliver to the Company or its designee at the Executive’s Termination of Employment all correspondence, memoranda, notes, records, drawings, sketches, plans, customer lists, product compositions, and other documents and all copies thereof, made, composed or received by the Executive, solely or jointly with others, that are in the Executive’s possession, custody, or control at such Termination of Employment and that are related in any manner to the past, present, or anticipated business of the Company and its Subsidiaries.

3.4 Remedies. The Executive acknowledges that a remedy at law for any breach or attempted breach of the Executive’s obligations under Section 3.1, Section 3.2 and Section 3.3 may be inadequate, agrees that the Company may be entitled to specific performance and injunctive and other equitable remedies in case of any such breach or attempted breach and further agrees to waive any requirement for the securing or posting of any bond in connection with the obtaining of any such injunctive or other equitable relief. The Company shall have the right to offset against amounts to be paid to the Executive pursuant to the terms hereof any amounts owed by the Executive to the Company or any of its Subsidiaries at the time of payment. The termination of this Agreement shall not be deemed to be a waiver by the Company of any breach by the Executive of this Agreement or any other obligation owed the Company or any of its Subsidiaries, and notwithstanding such a termination the Executive shall be liable for all damages attributable to such a breach.

3.5 Dispute Resolution. Subject to the Company’s right to seek injunctive relief in court as provided in Section 3.4 of this Agreement, any dispute, controversy or claim arising out of or in relation to or connection to this Agreement, including without limitation any dispute as to the construction, validity, interpretation, enforceability or breach of this Agreement, shall be settled by arbitration administered by the American Arbitration Association under its National Rules for the Resolution of Employment Disputes and judgment upon the award rendered by the arbitrator(s) may be entered in any court having jurisdiction thereof.

3.6 Acknowledgement of Parties. The Company and the Executive understand and acknowledge that this Agreement means that neither can pursue an action against the other in a court of law regarding any employment dispute, except for claims involving workers’ compensation benefits or unemployment benefits, and except as set forth elsewhere in this Agreement, in the event that either party notifies the other of the notifying party’s demand for arbitration under this Agreement. The Company and the Executive understand and agree that the provisions of Section 3.5, concerning arbitration, shall not include any controversies or claims related to any agreements or provisions (including provisions in this Agreement) respecting confidentiality, proprietary information, non-competition, non-solicitation, trade secrets, or breaches of fiduciary obligations by the Executive, which shall not be subject to arbitration.

3.7 Right to Consult Counsel. The Executive has been advised of the Executive’s right to consult with an attorney prior to entering into this Agreement.

3.8 Successors of the Company. The Company will require any successor (whether direct or indirect, by purchase, merger, consolidation or otherwise) to all or substantially all of the business and/or assets of the Company, by agreement in form and substance satisfactory to the Executive, expressly to assume and agree to perform this Agreement in the same manner and to the same extent that the Company would be required to perform this Agreement if no such succession had taken place. The failure of the Company to obtain such agreement prior to the effectiveness of any such succession shall be a breach of this Agreement and shall entitle the Executive to terminate this Agreement and receive compensation from the Company in the same amount and on the same terms as the Executive would be entitled hereunder if the Executive terminated the Executive’s employment for Good Reason. As used in this Agreement, “Company” as hereinbefore defined shall include any successor to its business and/or assets as aforesaid which executes and delivers the agreement provided for in this Section 3.8 or which otherwise becomes bound by all the terms and provisions of this Agreement by operation of law.

If the Executive should die while any amounts would still be payable to the Executive hereunder if the Executive had continued to live, all such amounts, unless other provided herein, shall be paid in accordance with the terms of this Agreement to the Executive’s designee or, if there be no such designee, to the Executive’s estate.

3.11 Amendment or Waiver. No provisions of this Agreement may be modified, waived or discharged unless such waiver, modification or discharge is agreed to in writing signed by the Executive and such officer as may be specifically designated by the Board (which shall not include the Executive). No waiver by either party hereto at any time of any breach by the other party hereto of or compliance with, any condition or provision of this Agreement to be performed by such other party shall be deemed a waiver of similar or dissimilar provisions or conditions at the same or at any prior or subsequent time. No agreements or representations, oral or otherwise, express or implied, with respect to the subject matter hereof have been made by either party, which are not set forth expressly in this Agreement. This Agreement constitutes the entire agreement between the Company and the Executive as to the subject matter hereof. No rights are granted to the Executive by virtue of this Agreement other than those specifically set forth herein.

3.13 Survival of the Executive’s Obligations. The Executive’s obligations under this Agreement shall survive regardless of whether the Executive incurs a Termination of Employment, voluntarily or involuntarily, by the Company or one of its Subsidiaries or by the Executive, with or without Cause.

person in the event this Agreement fails to comply with the requirements of Section 409A of the Code at any time.
