First Commonwealth Announces Share Repurchase Program

Indiana, PA., June 19, 2012 – First Commonwealth Financial Corporation (NYSE: FCF) today announced that its Board of Directors has authorized a share repurchase program of up to $50 million of the company’s common stock. Based on yesterday’s closing price of $6.22 per share as reported on the New York Stock Exchange, the authorized program represents approximately 8.0 million shares, or 8%, of the company’s outstanding shares as of March 31, 2012.

Under this program, management is authorized to repurchase shares through Rule 10b5-1 plans, open market purchases, privately negotiated transactions, block purchases or otherwise in accordance with applicable federal securities laws, including Rule 10b-18 of the Securities Exchange Act of 1934. Depending on market conditions and other factors, repurchases may be made at any time or from time to time, without prior notice. The company may suspend or discontinue the program at any time.

In connection with the repurchase program, the company has entered into a written trading plan under Rule 10b5-1 of the Securities Exchange Act of 1934 by which the company authorized the repurchase of up to $50 million of common stock at certain designated prices. However, the trading plan does not require that any shares be repurchased and there can be no assurance that any shares will be repurchased. The share repurchase program will continue to be in effect following the expiration of the trading plan, which expires on the earlier of August 31, 2012 or the date on which purchases are completed.
