Codorus Valley Bancorp, Inc.

Reports First Quarter Earnings for 2012

FOR IMMEDIATE RELEASE -- York, Pennsylvania (April 16, 2012) -- Codorus Valley Bancorp, Inc. (Nasdaq: CVLY), the parent company of PeoplesBank, A Codorus Valley Company, today announced net income available to common shareholders (earnings) of $2,102,000 or $0.50 per share, basic and diluted, for the quarter ended March 31, 2012, compared to the $1,266,000 or $0.31 per share basic, $0.30 per share diluted, for the quarter ended March 31, 2011.

The $836,000 or 66 percent increase in earnings for the first quarter of 2012, compared to the first quarter of 2011 was primarily the result of an increase in net interest income and a decrease in the provision for loan losses, which more than offset increases in noninterest expense and income taxes. The $938,000 or 12 percent increase in net interest income resulted primarily from a larger volume of earning assets, principally commercial loans, and a decrease in funding costs. The decrease in funding costs resulted from a larger proportion of low cost core deposits to total deposits and lower rates generally paid on all deposit products, which reflected unusually low market interest rates. The $425,000 or 63 percent decrease in the provision for loan losses reflected a low level of net loan charge-offs in the current quarter and adequacy of the existing allowance for loan losses. The $232,000 or 3 percent increase in noninterest expense was due to normal business growth, which included the impact of franchise expansion in the prior year. The $428,000 or 144 percent increase in the provision for income taxes was primarily the result of a 67 percent increase in the level of income before income taxes.

On March 31, 2012, total assets were approximately $1,030,000,000, representing a $69,000,000 or 7 percent increase above March 31, 2011. Compared to one year ago, asset growth occurred primarily in the commercial loan portfolio and was funded primarily by an increase in core deposits.
