Check the appropriate box below if the form 8-K filing is intended to simultaneously satisfy the filing obligation of the registrant under any of the following provisions (see General Instruction A.2. below):

On September 22, 2016, Home BancShares, Inc. (the “Company”) issued a press release announcing the commencement of an underwritten secondary public offering of shares of the Company’s common stock by the Chairman of the Company’s board of directors, John W. Allison. A copy of the press release is attached as Exhibit 99.1 hereto and is incorporated herein by reference.

On September 22, 2016, in connection with the underwritten secondary offering by the Company’s Chairman, the Company filed with the U.S. Securities and Exchange Commission (the “SEC”) a preliminary prospectus supplement (the “Prospectus Supplement”) relating to the Company’s registration statement on Form S-3 (File No. 333-208307) filed with the SEC on December 2, 2015.

The Prospectus Supplement states that as of September 20, 2016, the Company’s quarter-to-date performance is consistent with recent quarterly results. Including the impact of the one-time pre-tax charge of approximately $3.9 million, or $0.02 diluted earnings per share, resulting primarily from the write-off of the remaining FDIC indemnification assets and settlement charges paid to the FDIC in connection with the previously announced termination of the Company’s loss share agreements with the FDIC, the Company expects to report fully diluted earnings per share for the quarter ending September 30, 2016 in the range of $0.30 to $0.31. Excluding the FDIC loss share termination, the Company expects to report fully diluted earnings per share in the range of $0.31 to $0.32.

The Prospectus Supplement also states that on September 9, 2016, the Company entered into a non-binding letter of intent to acquire a Florida-based bank holding company having total assets of approximately $400 million for a purchase price of $88.5 million, consisting of approximately 20% cash and 80% shares of our common stock. This potential acquisition is subject to due diligence and the negotiation and execution of a definitive merger agreement and, if a definitive merger agreement is entered into, the acquisition would not be completed before early 2017.

Preliminary expectations of operating results and other financial data contained in this report are estimates only, and actual results may differ materially from those estimates, including as a result of factors discussed in the Prospectus Supplement and other documents filed by the Company with SEC from time to time. All preliminary estimates have been prepared by management, and BKD LLP, the Company’s independent public accounting firm, has not audited, reviewed, compiled or performed any procedures with respect to these estimates.
