ACNB CORPORATION REPORTS

2006 THIRD QUARTER EARNINGS

GETTYSBURG, Pa., November 10—ACNB Corporation reported net income of $1,906,000 for the third quarter of 2006, compared to $1,784,000 over the same period for 2005, an increase of 7%. Net income on a per share basis amounted to $.35 for the third quarter of 2006 and was $.33 for the same period in 2005. The most significant component of the Corporation’s total net income is net interest income, which increased by 1% to $6,225,000 for the quarter ended September 30, 2006, in comparison to $6,156,000 for the quarter ended September 30, 2005. Even with this increase, the Corporation’s interest expense has been increasing at a faster rate than its interest income over the last several quarters, and this trend is expected to continue in 2006.

The Corporation reported net income of $5,563,000 for the first nine months of 2006, compared to $5,595,000 over the same period for 2005, a decrease of less than 1%. Net income on a per share basis amounted to $1.02 for the first nine months of 2006 and was $1.03 for the same period in 2005. Net interest income increased by less than 1% to $18.72 million for the nine months ended September 30, 2006, in comparison to $18.68 million for the nine months ended September 30, 2005. Higher funding costs have been a significant factor impacting year-to-date earnings. In addition, total other income rose

by 12% for the first nine months of 2006. This increase over the same period of 2005 is primarily a result of gains on investment securities and increased revenues on insurance sales commissions and fee income.

Dividends paid to ACNB Corporation shareholders for the third quarter of 2006 totaled $1,142,000, or $.21 per share. This cash dividend of $.21 per share was paid on September 15, 2006, to shareholders of record on September 1, 2006. Aggregate dividends paid to shareholders year-to-date in 2006 were $3,425,000, or $.63 per share, as of September 15, 2006.

Total assets of ACNB Corporation on September 30, 2006, were $964 million—a 2% increase in comparison to September 30, 2005. Deposits were $669 million as of September 30, 2006, compared to $680 million as of the same date in 2005. Total loans increased by 11% to $529 million, as compared to September 30, 2005. Shareholders’ equity totaled $77.0 million on September 30, 2006, resulting in the Corporation and its banking subsidiary continuing to meet all minimum capital adequacy requirements to which they are subject for categorization as a well-capitalized financial institution.
