FIRST KEYSTONE ANNOUNCES

2013 EARNINGS

Berwick, Pennsylvania – JANUARY 31, 2014 - First Keystone Corporation (OTC BB: FKYS), parent company of First Keystone Community Bank, reported increased net income of $10,273,000 for the year ending December 31, 2013. Net income for 2013 was 1.01% greater than the $10,170,000 for 2012. Net income per share in 2013 was $1.87 while dividends were $1.04.

Net interest income continues to be impacted by the historic low interest rate environment. Total interest income declined to $30,961,000 as maturing loans and investments were replaced at lower interest rates. Total interest expense fell to $4,954,000. The Bank has been able to reduce interest expense by reducing its long-term borrowings and holding deposit rates low. As a result of these changes in income and expense, net interest income was $26,007,000.

Non-interest income increased 32.7%, or $1,942,000 due to increases in service charges and fees and net gains on sales of investment securities. Gains on the sales of loans declined due to the reduction in mortgage refinancings during the year. On the non-interest expense side, salaries and wages rose due to staff additions related to our Shickshinny and Dallas branches. Other non-interest expense was lower due to lower costs associates with other real estate and collections expenses.

As of December 31, 2013, total assets were up 10.0% to $901,565,000. Loans, net of unearned income, increased 3.2% to $446,518,000, while investment securities increased by 18.4% to $359,531,000. Deposits increased by 13.3% to $690,075,000.
