(a) Dismissal of Independent Registered Public Accounting Firm

On March 27, 2015, Eagle Financial Services, Inc. (the “Company”) informed Smith Elliott Kearns & Company, LLC (“SEK”) that SEK will be dismissed as the Company’s independent registered public accounting firm effective as of March 30, 2015. The decision to change the Company’s independent registered public accounting firm was approved by the Company’s Audit Committee.

The audit reports of SEK on the consolidated financial statements of the Company as of and for the years ended December 31, 2014 and 2013 did not contain any adverse opinion or disclaimer of opinion, nor were they qualified or modified as to uncertainty, audit scope, or accounting principles.

During the two fiscal years ended December 31, 2014 and 2013 and from January 1, 2015 through March 30, 2015, (i) there were no disagreements with SEK on any matter of accounting principles or practices, financial statement disclosure, or auditing scope or procedures that, if not resolved to SEK’s satisfaction, would have caused SEK to make reference in connection to their opinion to the subject matter of the disagreement and (ii) there were no “reportable events” as defined in Item 304(a)(1)(v) of Regulation S-K.

In accordance with Item 304(a)(3) of Regulation S-K, the Company provided SEK with a copy of this Current Report on Form 8-K prior to its filing with the Securities and Exchange Commission (the “SEC”). The Company requested that SEK furnish a letter addressed to the SEC stating whether or not it agrees with the statements made herein. A copy of SEK’s letter dated March 30, 2015 is filed as Exhibit 16.1 hereto.

(b) Engagement of New Independent Registered Public Accounting Firm

Additionally, based on the Audit Committee’s approval, on March 27, 2015, the Company selected Yount, Hyde & Barbour, P.C. (“YHB”) as the Company’s independent registered public accounting firm effective as of March 30, 2015 and for the fiscal year ending December 31, 2015.

During the two most recent fiscal years ended December 31, 2014 and 2013 and from January 1, 2015 through March 30, 2015, neither the Company nor anyone on its behalf consulted YHB regarding the application of accounting principles to a specified transaction, either completed or proposed, or the type of audit opinion that might be rendered on the Company’s financial statements, and no written report or oral advice was provided to the Company that YHB concluded was an important factor considered by the Company in reaching a decision as to any accounting, auditing or financial reporting issue. During the two most recent fiscal years ended December 31, 2014 and 2013 and from January 1, 2015 through March 30, 2015, neither the Company nor anyone on its behalf consulted YHB regarding any matter that was the subject of a disagreement or reportable event as defined in Regulation S-K, Item 304(a)(1)(iv) and Item 304(a)(1)(v), respectively.
