WSB Holdings, Inc. Announces Fourth Quarter and Year End Results

BOWIE, MD — January 31, 2013 - WSB Holdings, Inc. (Nasdaq: “WSB”), the parent company of Washington Savings Bank, F.S.B., (the “Bank”) today announced results of operations for both its fourth quarter and the twelve month period ending December 31, 2012.  WSB reports net earnings of $578,000 or $0.07 per basic and diluted share for the three months ended December 31, 2012, compared to net earnings of $283,000 or $0.04 per basic and diluted share for the comparable period of the prior year. WSB reports net earnings for the twelve month period ending December 31, 2012 of $1.0 million, or $0.13 per basic and diluted share, compared to net earnings of $1.2 million, or $0.16 per basic and diluted share, for the twelve month period ending December 31, 2011.

Net interest income decreased $565,000, or 19%, and $1.5 million, or 12%, for the three and twelve month periods ended December 31, 2012 as compared to the same periods last year.  As we continue to experience low loan demand,  there has been a decrease in our loans held-for-investment portfolio which has contributed to our interest income decreasing by 22% and 15%, respectively, for the three and twelve months ending December 31, 2012. This decrease was partially offset by decreases in our interest expense of 29% and 23% for the three and twelve months ending December 31, 2012.  This decrease in interest expense is the result of continued efforts to reduce our higher cost liabilities.  Non-interest income increased $1.1 million, or 142%, and $828,000, or 22%, for the three and twelve months ended December 31, 2012 as compared to the same periods last year.  This is the result of an increase in our rental income, gain on the sale of loans sold in the secondary market and gain on the sale of real estate acquired in settlement of loans and, during the three-month period ended December 31, 2012, the sale of securities in our investment portfolio as discussed below.

On September 10, 2012, we announced the execution of a definitive merger agreement that provides for the acquisition of WSB Holdings, Inc. by Old Line Bancshares, Inc. for approximately $49 million, or approximately $6.12 per share, in cash and stock, subject to adjustment including adjustments relating to the value of our investment portfolio (the “total consideration”).  In accordance with the merger agreement, WSB has been repositioning a portion of the investment portfolio by selling existing securities and purchasing new securities with Old Line Bancshares’ consent.  Such sales and repurchases resulted in a gain of $760,000 pretax, $460,000 net of tax, during the three months ending December 31, 2012, offsetting the decrease in net interest income and resulting in a net profit for the fourth quarter.  We expect to continue to reposition the investment portfolio in order to attempt to minimize any potential adjustment to the total consideration upon closing of the merger.

Non-interest expenses increased by $174,000, or 5%, for the three month period ending December 31, 2012 as compared to the same period last year as a result of an increase in salaries and benefits and additional professional fees associated with the pending merger.  Non-interest expense increased $68,000, or .50%, for the twelve month period as a result of increase in salaries and benefits, offset by lower FDIC premiums compared to the same twelve month period last year.

The Bank remains well in excess of the regulatory levels for being “well capitalized” and continues to look for profitable opportunities in this market to grow the Bank.
