Gerald Bazewicz President and Chief Executive Officer (570) 752-3671 Exhibit 99.1 PRESS RELEASE FIRST KEYSTONE ANNOUNCES RECORD 2009 EARNINGS Berwick, Pennsylvania - FEBRUARY 1, 2010 - First Keystone Corporation (OTC BB: FKYS), parent company of First Keystone National Bank, reported record net income of $7,937,000 or $1.46 per share for the year ending December 31, 2009, as compared to $7,551,000 or $1.39 per share in 2008. For the fourth quarter ending December 31, 2009, net income was $1,586,000 as compared to $1,716,000 for the same period in 2008, a decrease of 7.6% due to a discovered defalcation which was expensed in the fourth quarter. Management believes the defalcation will be a covered loss, less the deductible. The insurance proceeds will be recognized when received in 2010. Earnings for 2009 were positively impacted by an improving net margin. An increase in non-interest income also accounted for the improvement in 2009 earnings. Overall asset quality remains strong with non performing assets to total assets of 0.45% and an allowance for loan losses at 1.31% of total loans. Cash dividends per share amounted to $.92 for year ending December 31, 2009, an increase of 3.4% from the $.89 paid in 2008. Total assets and deposits increased to $758,330,000 and $580,567,000 as of December 31, 2009, an increase of 6.1% and 15.0%, respectively. Loans, net of unearned income, amounted to $406,697,000 as of December 31, 2009.
