JACKSONVILLE BANCORP ANNOUNCES

NET INCOME OF $1.3 MILLION FOR THE QUARTER

JACKSONVILLE, FLA., May 8, 2012 / PRNewswire /— Jacksonville Bancorp, Inc. (“the Company”) (NASDAQ: JAXB), holding company for The Jacksonville Bank (“Bank”), reported net income for the three months ended March 31, 2012 of $1.3 million, or $.22 per basic and diluted common share, compared to the first quarter 2011 net income of $439 thousand, or $.07 per basic and diluted common share. Book value and tangible book value per common share at March 31, 2012 were $5.23 and $4.42, respectively.

Total assets were $585.8 million at March 31, 2012, compared to $624.6 million at March 31, 2011. Net loans decreased by 9.5% to $446.0 million as of March 31, 2012, compared to $492.6 million as of March 31, 2011. Total deposits decreased 3.1% to $513.5 million as of March 31, 2012, compared to $529.8 million as of March 31, 2011. Total deposits as of March 31, 2012 increased $39.6 million from December 31, 2011 driven primarily by an increase in time deposits of $29.7 million and money market, NOW and savings deposits of $12.0 million offset by a decrease in noninterest-bearing deposits of $2 million.

The Bank exceeded regulatory standards of being “well capitalized” with total risk-based capital, Tier 1 risk-based capital and Tier 1 leverage capital at 10.3%, 9.0% and 7.5%, respectively, at March 31, 2012.

As of March 31, 2012, nonperforming assets were $56.7 million, or 9.68% of total assets, compared to $40.6 million, or 6.51% of total assets a year ago. The increase in nonperforming assets from the first quarter of 2011 to the first quarter of 2012 is primarily a result of the challenging current economic environment and the market in which the Company operates. As of March 31, 2012, nonperforming assets acquired in the ABI merger were $13.0 million, or 23.1%, of total nonperforming assets.

The following table presents information concerning nonperforming assets as of the last five quarters :

The increase in loans past due 30-89 days in the current quarter, still accruing interest, was driven by the continued softening of local real estate markets. Nonperforming loans increased $2.2 million from $46.9 million for the three months ended December 31, 2011 to $49.1 million for the three months ended March 31, 2012.

The allowance for loan losses was 2.85% of total loans at March 31, 2012, compared to 2.25% for the comparable period in 2011 and 2.82% at December 31, 2011. Provision for loan loss expense was $72 thousand for the three-month period ended March 31, 2012, compared to $1.9 million for the same period in 2011. The Company has

recorded net charge-offs of $14 thousand for the three-month period ended March 31, 2012, compared to $3.7 million for the comparable period in 2011. The decreased level of net charge-offs for the three months ended March 31, 2012 is due to the large amount of charge-offs the Company recorded in 2011 in conjunction with its overall strategy to reduce the level of substandard assets by taking control of properties through aggressive foreclosure efforts. Further reducing the level of net charge-offs is the slowing of declines in real estate values.

As previously disclosed, the Company has executed a financial advisory agreement with an investment banking firm (the “Firm”). Under the agreement, the Firm has agreed to work with Company management to assist in raising capital as well as advising the Company on reducing classified assets.

Price Schwenck, President and CEO of the Company, made these comments: “The high level of nonperforming assets, stemming in large part from a 50% decline in real estate values in recent years, remains very challenging. As we’ve previously reported, we are moving forward with strategies designed to strengthen our balance sheet. The economy appears to be improving in Jacksonville, and we believe there is tremendous opportunity to grow our franchise. The momentum during the first quarter is encouraging.”

Net income for the three-month period ended March 31, 2012 increased to $1.3 million, compared to a net income of $439 thousand during the comparable period in 2011. The increase in net income was driven primarily by the reduction in provision for loan loss expense. Pre-provision, pre-OREO, pre-M&A and pre-tax earnings were $1.7 million for the quarter ended March 31, 2012, compared to $2.3 million for the same period a year ago. The decrease in pre-provision, pre-OREO, pre-M&A, and pre-tax earnings from the previous year was due to a decrease in average earning assets, primarily driven by a reduction in loan balances of $44.8 million.

Net interest income decreased by $561 thousand to $5.3 million during the three-month period ended March 31, 2012 when compared to the same period in the prior year. This was due primarily to a decrease in average earning assets of $48.5 million as of March 31, 2012 when compared to the same period in the prior year. The yield on these assets decreased to 4.98% for the three-month period ended March 31, 2012, compared to 5.35% for the same period in the prior year. In addition, loan yields were down due to a decrease in the accretion recognized on acquired loans when compared to the same period in 2011. This resulted in reduced interest income of approximately $1.1 million for the three-month period ended March 31, 2012 when compared to the same period in the prior year.

Interest expense decreased by $508 thousand during the three-month period ended March 31, 2012 when compared to the same periods in the prior year. This was partially due to a decrease in the average cost of interest-bearing liabilities to 1.20% for the three-month period ended March 31, 2012, compared to 1.50% for the same period in the prior year. This decrease reflected the ongoing reduction in interest rates paid on deposits as a result of the re-pricing of deposits in the current market environment.

Noninterest income for the three-month period ended March 31, 2012 increased to $437 thousand when compared to $396 thousand in the comparable period in the prior year. The increase was driven largely by a $70 thousand fee related to a loan pre-payment received during the first quarter of 2012.

Noninterest expense remained relatively flat at $4.4 million for the three months ended March 31, 2012, compared to $4.3 million during the same period in 2011. Increases to compensation and OREO expenses were offset by reductions in data processing, occupancy and regulatory assessments.

There was no income tax expense recorded during the period ended March 31, 2012. The Company recorded a full valuation allowance against its deferred taxes at December 31, 2011. This was substantially due to the fact that it was “more likely than not” that the benefit would not be realized in future periods due to Section 382 of the Internal Revenue Code. During the three-month period ended March 31, 2012, a portion of the valuation allowance attributable to the deferred tax assets has been reduced due to the decrease in the deferred tax asset.
