Gerald Bazewicz President and Chief Executive Officer (570) 752-3671 Exhibit 99.1 PRESS RELEASE FIRST KEYSTONE ANNOUNCES FIRST QUARTER 2007 EARNINGS Berwick, Pennsylvania - April 30, 2007 - First Keystone Corporation (OTC BB: FKYS), parent company of The First National Bank of Berwick, reported net income of $1,434,000 for the quarter ending March 31, 2007, or $.32 per share, down 5.9% from the $.34 earnings per share in the first quarter of 2006. Cash dividends paid increased to $.22 per share as compared to $.21 paid in the first quarter of 2006, an increase of 4.8%. Per share data was adjusted to reflect a 5% stock dividend paid December 5, 2006. President J. Gerald Bazewicz reported, "While we are pleased with our financial results in the first quarter of 2007, the continued presence of a flat or inverted yield curve has constrained revenue growth. The tightening of our net-interest margin was partially offset by a decrease in our provision for loan losses, and increase of 9.9% in non-interest income and continued excellent control over non-interest expenses, which increased only 2.4%. The reduction in our provision for loan losses was primarily a result of a decline in charge-offs and continued satisfactory asset quality. Finally, our allowance for loan losses is 1.47% of total loans as of March 31, 2007." Total assets and deposits increased to $523,800,000 and $392,646,000 as of March 31, 2007, an increase of 2.0% and 6.2% respectively over first quarter 2006. Loans, net of unearned income, increased 5.3% to $252,487,000.
