BCSB Bancorp, Inc. Baltimore County Savings Bank

BCSB BANCORP, INC. REPORTS RESULTS FOR THE QUARTER ENDED MARCH 31, 2012

BCSB Bancorp, Inc. (the "Company") (NASDAQ: BCSB), the holding company for Baltimore County

Savings Bank (the "Bank") reported net income of $574,000 for the three month period ended March 31,

2012, which represents the second quarter of its 2012 fiscal year, as compared to net income of $188,000 for the three months ended March 31, 2011. For comparison purposes, when consideration is given to dividends and discount accretion on preferred shares issued under the U.S. Treasury's TARP Capital Purchase Program, the Company reported net income available to common stockholders of $574,000 or $0.19 per basic share and $0.18 per diluted share for the three months ended March 31, 2012, compared to a net loss

available to common stockholders of $229,000 or ($0.08) per basic and diluted common share for the three

months ended March 31, 2011. The Company repaid TARP on January 26, 2011 and was required to accelerate accretion of the remaining discount on the preferred stock, thereby reducing net income available to common shareholders by approximately $310,000 during the three months ended March 31, 2011. The Company was able to repay TARP without raising additional capital, which would have been dilutive to shareholders.

Net income for the six months ended March 31, 2012 was $1,036,000, as compared to net income of

$233,000 for the six months ended March 31, 2011. For comparison purposes, when consideration is given to dividends and discount accretion on preferred shares issued under the U.S. Treasury's TARP Capital Purchase Program, net income available to common stockholders was $1,036,000 or $0.34 per basic share and $0.33 per diluted share for the six months ended March 31, 2012, compared to a net loss available to common stockholders of $340,000 or ($0.11) per basic and diluted common share for the six months ended March 31, 2011.

During the three and six months ended March 31, 2012, earnings were favorably impacted by increases in net interest income, increases in non-interest income and reductions in non-interest expense. Provision for loan losses increased by $300,000 during the three months ended March 31, 2012 and decreased by

$200,000 during the six months ended March 31, 2012, as compared to the same periods in the prior fiscal year.

President and Chief Executive Officer Joseph J. Bouffard commented, "We are encouraged by the trend of increased earnings. Core areas of operating results have improved, including net interest income and operating expenses. We remain focused on resolving asset quality issues despite stubbornly problematic economic conditions. During the most recent quarter ended March 31, 2012, we successfully disposed of foreclosed real estate while recognizing approximately $345,000 in gains from sale of those properties."

(1)Tangible book value provides a measure of tangible equity on a per share basis. It is determined by methods other than in accordance with Accounting Principles Generally Accepted in the United States ("GAAP") and, as such, is considered to be a non-GAAP financial measure. Management believes the presentation of Tangible book value per share is meaningful supplemental information for shareholders. We calculate Tangible book value per common share by dividing tangible common equity by common shares outstanding,

as of period end.
