ACNB CORPORATION NAMED TO

KBW BANK HONOR ROLL

GETTYSBURG, PA, May 1—On April 14, KBW, a Stifel company and an investment bank and broker-dealer that specializes in the financial services sector, named ACNB Corporation to its 2013 KBW Bank Honor Roll. This Bank Honor Roll features the top 31 U.S. banking institutions based upon superior performance.

Thomas A. Ritter, President & Chief Executive Officer of ACNB Corporation, commented, “Our long-standing commitments to bank safety and soundness and to effective risk management practices have positioned ACNB Corporation among the most consistent and reliable institutions in the banking industry.  Very simply, our employees do very good work, and their commitment to excellence is repeated year after year, regardless of prevailing economic conditions.  ACNB Corporation’s subsidiary, ACNB Bank, observed its 157th anniversary on April 11, 2014.  To be recognized on the 2013 KBW Bank Honor Roll is a certain testimonial to all of our colleagues who have served before us, and to those who work here now.  We are honored by this award.”

Bank Honor Roll winners are publicly-traded banking institutions with more than $500 million in total assets that meet the following three conditions:

·                  No annual loss reported in net income per share before extraordinary items over the past 10 years;

·                  2013 annual reported net income per share before extraordinary items equal to or greater than peak net income per share over the past 10 years; and,

·                  Consecutive increases in net income per share before extraordinary items since 2009.

KBW found that 31 banking institutions, out of nearly 400 total companies screened, now qualify for inclusion on the annual KBW Bank Honor Roll, down from 47 institutions in the prior year.

A total of four new members made this year’s list: ACNB Corporation; First Defiance Financial Corp.; Signature Bank; and, WesBanco, Inc.

There are also 27 returning members that made this year’s list: 1st Source Corporation; Auburn National Bancorporation, Inc.; BancFirst Corporation; The Bank of Kentucky Financial Corporation; Cass Information Systems, Inc.; Center Bancorp, Inc.; Century Bancorp, Inc.; Eagle Bancorp, Inc.; Enterprise Bancorp, Inc.; ESB Financial Corporation; First Financial Bankshares, Inc.; German American Bancorp, Inc.; Greene County Bancorp, Inc.; Hingham Institution for Savings; Lakeland Financial Corporation; M&T Bank Corporation; National Bankshares, Inc.; Northwest Bancshares, Inc.; Oak Valley Bancorp; Prosperity Bancshares, Inc.; S.Y.

“We believe it is fair to say that the past decade has been one of the most challenging in the history of U.S. banking, as 496 banks failed during that period,” noted Fred Cannon, KBW Director of Research. “The Bank Honor Roll is a way for KBW to acknowledge companies that have managed to excel during these tumultuous times and position their companies for further growth in what remains a rate-challenged environment.”

According to KBW, in terms of stock price performance, Bank Honor Roll companies significantly outperformed the banking industry during the five-year period between 2008 and 2013.  With average price appreciation of 13.4% compounded annually, the KBW Honor Roll banks outperformed the KBW Bank Index (BKX) and the KBW Regional Banking Index (KRX) five-year compounded annual growth rates of 9.3% and 5.7%, respectively.

Further, while 2014 thus far has proved to be challenging for overall equity market performance, the KBW Bank Honor Roll members continue to outperform.  In 2014 to date through April 10, despite falling 0.5% on average, the KBW Honor Roll banks slightly outperformed the BKX’s 0.6% decline and more significantly outperformed the KRX’s 4.1% decline.  The KBW Bank Honor Roll members also modestly outperformed the market, as the SPX fell 0.8% in 2014 to date.
