OBA Financial Services, Inc. Announces 4^th Quarter Results

GERMANTOWN, MARYLAND: August 16, 2011 – OBA Financial Services, Inc., (NASDAQ – OBAF) (“Company”), the parent company of OBA Bank (“Bank”), announces net income of $857 thousand, or $0.20 per share, for the Company’s fiscal year ended June 30, 2011 as compared to a net loss of $710 thousand, or $0.17 loss per share, for the fiscal year ended June 30, 2010.

For the fourth quarter of the Company’s fiscal year 2011 which ended June 30, 2011, the Company announces net income of $123 thousand, or $0.03 per share, as compared to net income of $82 thousand, or $0.02 per share, for the quarter ended June 30, 2010.

The Company’s annual income was significantly impacted by an increase in non-interest income of $1.8 million for the year ended June 30, 2011. The increase in non-interest income reflects a decrease in impairment losses on investment securities of $1.9 million. The decrease in impairment losses is the result of the Company’s previous sale of its bank and bank holding company pooled trust preferred securities in March 2010.

Income Statement

The Company’s net interest income for the fiscal year ended June 30, 2011 was $12.0 million compared with $10.1 million for the fiscal year ended June 30, 2010, or an increase of 18.9%. The Company continued to pay down higher cost borrowings and certificates of deposit.

The Company’s net interest income for the fourth quarter of the fiscal year ended June 30, 2011 was $2.9 million as compared to $2.8 million in the same period the prior year, or a 4.7% increase.

The Company’s non-interest expense increased to $11.0 million for the fiscal year ended June 30, 2011 from $9.3 million for the fiscal year ended June 30, 2010, or 18.3%. The increase is primarily a result of the addition of several commercial bankers as part of the Bank’s business strategy to increase the commercial loan portfolios, as well as the addition of a residential loan manager, increased legal, regulatory, and accounting costs necessary to operate as a public company, and increased marketing expenses.

Balance Sheet

Total assets grew 3.3% to $386.4 million at June 30, 2011 from $374.1 million at June 30, 2010.

Total loans increased $4.1 million to $281.9 million at June 30, 2011 from $277.8 million at June 30, 2010.

Total deposits increased by $41.3 million, or 19.2%, on a linked-quarter basis, from $215.7 million at March 31, 2011 to $257.0 million at June 30, 2011 as the Company increased money market deposits as a result of a promotion during the quarter ended June 30, 2011.

Borrowings decreased 20.9% from $57.1 million at June 30, 2010 to $45.2 million at June 30, 2011 as the Company continued to pay down higher cost borrowings.

Equity and Capital

Stockholders’ Equity remained essentially unchanged at $80.9 million at June 30, 2011 as compared to $80.2 million at June 30, 2010. The Company remains well-capitalized at all levels with ratios well in excess of regulatory minimums.

Asset Quality

Total non-performing assets to total assets increased to 1.47% at June 30, 2011 from 0.17% at June 30, 2010. The increase was made up of two loan relationships with not-for-profit entities that have collateral value well in excess of the loan value. Based on the value of the collateral, no specific allowances are required for these loans.

The allowance for loan losses to total loans increased to 0.80% at June 30, 2011 from 0.63% at June 30, 2010 and, on a linked-quarter basis, from 0.77% at March 31, 2011.
