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

On June 30, 2026, the Board of Directors of Farmers & Merchants Bancorp, Inc. (the “Company”) determined to appoint Gregory R. Allen to fill an open vacancy on its Board of Directors. September 29, 2026 will mark Mr. Allen’s first meeting as a member of the Company’s Board of Directors.

As a member of the Company’s Board of Directors, Mr. Allen will receive fees in accordance with those paid to non-employee members of the Company’s Board of Directors in general. Effective January 1, 2026, the Company’s Board fee structure for 2026 was set as follows:

In addition, the Company, through its wholly-owned commercial bank subsidiary, regularly engages in the lending of money to Directors and executive officers, including their related interests. All such loans (i) are made in the ordinary course of business, (ii) are made on substantially the same terms, including interest rates and collateral, as those prevailing at the time for comparable transactions with other persons, and (iii) do not involve more than a normal risk of collectability or present other unfavorable features. It is uncertain at this point in time as to which Board committees on which Mr. Allen will serve.

Mr. Allen has no family relationship with any director or executive officer of the Company or any of its affiliated subsidiaries. Since the beginning of the Company’s last fiscal year, neither Mr. Allen nor any member of his immediate family have been customers of, or have had transactions in excess of $120,000 with the Company or any of its affiliated subsidiaries, which would be reportable under Item 404(a) of SEC Regulation S-K and no such transactions are currently proposed.
