Item 4.01 Changes to Registrant’s Certifying Accountant

(a)   On April 14, 2014, the audit committee of the board of directors (the “Audit Committee”) of Carter Validus Mission Critical REIT, Inc. (the “Company”) approved and authorized the Company to, and the Company did, dismiss Ernst & Young, LLC (“Ernst & Young”) as the Company’s registered public accounting firm, effective immediately.

The reports of Ernst and Young on the Company’s financial statements for the years ended December 31, 2013 and 2012 contained no adverse opinion or disclaimer of opinion, and such reports were not qualified or modified as to uncertainty, audit scope, or accounting principles. During the years ended December 31, 2013 and 2012, and through the date of this Current Report on Form 8-K, there have been no (i) disagreements between the Company and Ernst & Young on any matter of accounting principles or practices, financial statement disclosure, or auditing scope or procedure, which disagreement(s), if not resolved to the satisfaction of Ernst & Young, would have caused it to make reference to the subject matter of the disagreement(s) in connection with its reports, or (ii) “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 Ernst & Young with a copy of the disclosure it is making on this Form 8-K prior to the time this Form 8-K was filed with the Securities and Exchange Commission (the “SEC”). The Company requested that Ernst & Young furnish a letter addressed to the SEC stating whether it agrees with the statements made herein, and if not, stating the respects in which it does not agree. A copy of the Ernst & Young letter, dated April 16, 2014, is filed as Exhibit 16.1 hereto.

On April 14, 2014, the Audit Committee approved the engagement of KPMG, LLP (“KPMG”) as the Company’s independent registered public accounting firm. During the two most recent fiscal years ended December 31, 2013 and 2012, and through the date of this Current Report on Form 8-K, neither the Company nor anyone on its behalf consulted with KPMG regarding (1) the application of accounting principles to a specified transaction, either completed or proposed; (2) the type of audit opinion that might be rendered on the Company’s financial statements; or (3) any matter that was either the subject of a disagreement or event identified in response to Item 304(a)(1) of Regulation S-K (there being none).

Item 9.01 Financial Statements and Exhibits.
