George Gleason, Chairman and Chief Executive Officer

Eighth, acquisitions were an important part of our story in 2015 and our two pending acquisitions, both announced in the quarter just ended, are, in our opinion, of particular strategic importance and value. Our pending acquisition of Community & Southern Bank, which we announced on October 19, 2015, will be our largest acquisition to date. Community & Southern provides us 47 strategically located and highly complementary Georgia banking offices and one Florida banking office, a large number of talented bankers, particular expertise in both direct and indirect consumer credit, an important loan operations group, two important loan and business analytics groups, and numerous other team members and capabilities which will enhance our Community Banking, loan administration and other business functions. Our pending acquisition of C1 Bank, which we announced on November 9, 2015, will provide us 32 strategically located and highly complementary Florida banking offices, including offices in some of Florida’s highest growth and strongest economic markets. We believe that C1’s unique culture and leadership in technology and innovation will be transformational in our quest to be an industry leader in best-of-class customer experiences and operational efficiency. Both transactions are expected to close in the first half of 2016.

We continue to believe we have substantial capacity for deposit growth within our existing branch network and from established wholesale funding sources, and we expect our pending acquisitions to augment our deposit growth capacity.

Tyler Vance, Chief Operating Officer and Chief Banking Officer of Bank of the Ozarks, Inc.

While our efficiency ratio will vary from quarter to quarter, especially in quarters where we have significant unusual items of income and non-interest expense, we have stated in recent conference calls that we expect to see a generally improving trend in our efficiency ratio in the coming years. This is predicated upon a number of factors, including


our expectation that we will ultimately utilize a large amount of the current excess capacity of our extensive branch network; our expectation that our core software conversion and improvement projects over the past two years will provide greater functionality for our customers and employees creating opportunities for enhanced operational efficiency; our expectation of achieving additional productivity gains by reallocating resources from Stabilized Properties Group and a few underperforming Community Banking elements to more productive geographies and areas of business; and our expectation that we will achieve significant efficiencies from our pending acquisitions including efficiencies from the adoption of Community & Southern Bank’s consumer lending platform and the deployment of numerous technology applications from C1 Bank’s C1 Labs innovation group.

*********************

We will incur additional unusual items of non-interest expense in future quarters, including non-interest expense related to the closing and core system conversions of acquisitions. As for our two pending acquisitions, Community & Southern Bank and C1 Bank, we can expect acquisition-related and system conversion expenses to be incurred in each quarter of 2016. We expect both transactions will close in the first half of 2016, and we anticipate both core systems conversions will occur in the second half of 2016.
