President's Statement

It is with great pride that we announce today Mid Penn's 2011 third quarter and year-to-date performance. As you will see in the summary above, Mid Penn had a strong third quarter and first nine months, particularly when compared to the same periods in 2010. Even in a very difficult economic, regulatory, and political environment, we have kept the train of success moving further and further away from our difficult 2009. We have accomplished this through a commitment to true community banking. To us, that means finding the best means to provide the banking products and services our customers want and need, and doing so in the most cost effective manner. Through the first nine months of 2011, that plan is clearly working.

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 third quarter of 2011. The dividend is payable November 28, 2011 to shareholders of record on November 9, 2011.

Management considers subsequent events occurring after the balance sheet date for matters which may require adjustment to, or disclosure in, the consolidated financial statements.  The review period for subsequent events extends up to and including the filing date of a public company's consolidated financial statements when filed with the Securities and Exchange Commission ("SEC").  Accordingly, the financial information in this announcement is subject to change.
