JACKSONVILLE BANCORP, INC. ANNOUNCES QUARTERLY EARNINGS

Jacksonville Bancorp, Inc. (NASDAQ Capital Market – JXSB) reported unaudited net income for the three months ended March 31, 2014, of $840,000, or $0.47 per share of common stock, basic and diluted, compared to net income of $1,012,000, or $0.54 per share of common stock, basic and diluted, for the three months ended March 31, 2013. Basic and diluted average shares outstanding at March 31, 2014 were 1,794,635 and 1,801,970, respectively. Basic and diluted average shares outstanding at March 31, 2013 were 1,877,873 and 1,878,145, respectively. Net income decreased $172,000 during the first quarter of 2014 due to a decrease of $488,000 in noninterest income, partially offset by an increase of $176,000 in net interest income and decreases of $15,000 in noninterest expense and $125,000 in income taxes.

The decrease of $488,000 in noninterest income during the first quarter of 2014 was primarily due to a decrease of $484,000 in gains on the sales of securities. Noninterest income was also impacted by a decrease of $58,000 in net income from mortgage banking operations. These decreases were partially offset by an increase of $45,000 in commission income. The increase in net interest income during the first quarter of 2014 reflected an increase of $94,000 in interest income and a decrease of $82,000 in interest expense, as compared to the first quarter of 2013. The Company benefitted from an increase of $158,000 in interest income on mortgage-backed securities as mortgage loan rates increased and prepayment speeds slowed. For the three months ended March 31, 2014 our net interest margin was 3.63% compared to 3.70% for the three months ended December 31, 2013 and 3.41% for the three months ended March 31, 2013. The ratio of interest earnings assets to interest bearing liabilities at March 31, 2014 and March 31, 2013 was 1.24x and 1.22x, respectively.

The provision for loan losses remained stable at $30,000 during the first quarters of 2014 and 2013. Management reviews the allowance for loan losses quarterly and has determined the allowance for loan losses at March 31, 2014 to be adequate. Noninterest expense decreased $15,000 during the first quarter of 2014, primarily due to decreases of $29,000 in professional fees and $15,000 in compensation and benefits expense, partially offset by increases in other expenses. The $125,000 decrease in income taxes reflects the lower level of taxable income during the first quarter of 2014.

Total assets at March 31, 2014 were $315.1 million compared to $318.4 million at December 31, 2013. Total deposits at March 31, 2014 were $256.2 million, compared to $251.7 million at December 31, 2013. Total stockholders’ equity increased to $42.4 million at March 31, 2014 from $41.1 million at December 31, 2013. The Company reported a book value per share of $23.32 and a tangible book value per share of $21.82 at March 31, 2014. At March 31, 2014, Jacksonville Savings Bank exceeded its applicable regulatory capital requirements with Tier 1 leverage, Tier 1 risk-based capital, and total risk-based capital ratios of 11.9%, 17.6%, and 18.9%, respectively.
