On April 21, 2022, the Audit Committee of the Board of Directors of Farmers & Merchants Bancorp. (the “Company) approved the engagement of Eide Bailly LLP (“Eide Bailly”) to serve as our independent registered public accounting firm for the fiscal year ending December 31, 2022, and dismissed Moss Adams LLP (“Moss Adams”) as the Company’s independent registered public accounting firm.

During the Company’s fiscal years ended December 31, 2021 and 2020, and in the subsequent interim period through April 21, 2022, neither we nor anyone acting on our behalf consulted with Eide Bailly regarding either (i) the application of accounting principles to a specific transaction, either completed or proposed; (ii) or the type of audit opinion that might be rendered on our consolidated financial statements, in either case where a written report was provided or oral advice was provided that Eide Bailly concluded was an important factor considered by the Company in reaching a decision as to an accounting, auditing or financial reporting issue; or (iii) any matter that was either the subject of a disagreement (as defined in Item 304(a)(1)(iv) of Regulation S-K and the related instructions to Item 304 of Regulation S-K) or a reportable event (as defined in Item 304(a)(1)(v) of Regulation S-K).

Moss Adams’ reports on our consolidated financial statements and the effectiveness of internal control over financial reporting, which were included in the Company’s Annual Reports on Form 10-K for the fiscal years ended December 31, 2021 and 2020, did not contain an adverse opinion or disclaimer of opinion and were not qualified or modified as to uncertainty, audit scope or accounting principles.

During the Company’s fiscal years ended December 31, 2021 and 2020, and in the subsequent interim periods through April 21, 2022, (i) there were no disagreements within the meaning of Item 304(a)(1)(iv) of Regulation S-K between the Company and Moss Adams on any matter of accounting principles or practices, financial statement disclosure, or auditing scope or procedure, which disagreements, if not resolved to Moss Adams’ satisfaction, would have caused it to make reference thereto in its reports; and (ii) there were no reportable events as defined in item 304(a)(1)(v) of Regulation S-K.

We have provided Moss Adams with a copy of the foregoing disclosures and have requested that Moss Adams furnish us with a letter addressed to the United States Securities and Exchange Commission stating whether it agrees with the above disclosures related to their firm. Attached as Exhibit 16.1 is a copy of that letter, dated April 21, 2022.
