President's Statement

In a year of continuing earnings improvement for Mid Penn, we saved the best for last.  Our fourth quarter income was very strong compared to both the fourth quarter of 2010 and the third quarter of 2011.  The formula for success throughout 2011 reached a zenith in the fourth quarter.  That formula included improved asset quality and an accordingly lower provision for loan and lease losses; lower cost of funds through an improvement in deposit mix; consistent management of controllable expenses; and, finally, some measurable loan growth.  Although we faced economic, regulatory, and legislative pressures throughout 2011, we adjusted and delivered performance of which we take great pride.  Based on that 2011 performance, and understanding that we continue to face many of those same pressures, we take great confidence into 2012.

On behalf of the Mid Penn Board of Directors, I also announce today that Mid Penn Bancorp, Inc. is declaring a cash dividend of $0.05 per share on our common stock, based upon the results of operations for the fourth quarter of 2011. The dividend is payable February 27, 2012 to shareholders of record on February 8, 2012.
