Dear Shareholder:

The proposed acquisition of Reliant Bank by Commerce Union Bancshares, Inc. and the subsequent planned combination of Commerce Union Bank and Reliant Bank is well underway. On July 3, 2014, Commerce Union Bancshares, Inc. filed a preliminary registration statement on Form S-4 with the Securities and Exchange Commission to register our common stock in connection with the transaction; this was a major first step in the approval process. Our “Interagency Bank Merger Act Application” was filed with the Federal Reserve Bank of Atlanta and the Tennessee Department of Financial Institutions on July 30, 2014. At this time we expect to receive approval of this proposed merger before the end of 2014.

Commerce Union Bancshares, Inc. reported net income of $906,825 for the first six months of 2014 after experiencing $489,406.48 in expenses related to the merger. This compares to $901,534 for the same period in 2013, which did not include any unusual expenses. During the first six months of 2014 net loans increased to $228,728,900 from $213,207,597, an increase of 7.28%, while total assets increased to $274,447,396 from $253,154,704, an increase of 8.41%. Total deposits increased to $216,596,106 from $197,044,432, an increase of 9.92%. We have maintained our net interest margin at 4.12%, on average, through June 30, 2014.
