                               BCSB BANCORP, INC.
                REPORTS RESULTS FOR QUARTER ENDING MARCH 31, 2009

BCSB Bancorp, Inc. (NASDAQ: BCSB), the holding company for Baltimore County
Savings Bank, FSB, reported net income of $102,000 or ($0.02 loss) per basic and
diluted common share for the three month period ended March 31, 2009, which
represents the second quarter of its 2009 fiscal year. This compares to net
income of $55,000 or $.02 per basic and diluted common share for the three
months ended March 31, 2008.

Net income for the six months ended March 31, 2009 was $342,000 or $.06 per
basic and diluted common share, as compared to net income of $148,000 or $.05
per basic and diluted common share for the six months ended March 31, 2008.

During the three and six months ended March 31, 2009, the Company benefited from
increases in net interest income and non-interest income as compared to
corresponding periods during the prior fiscal year. These improvements in
earnings were partially offset by increases in FDIC insurance premiums on
deposits and loan loss provisions during the three and six months ended March
31, 2009 of $150,000 and $300,000, respectively. Loan loss provisions during the
current fiscal year were necessary to address continued declines in general
economic conditions. Basic and diluted earnings per common share during the
current fiscal year were negatively impacted by dividends payable on preferred
shares issued under the U.S. Treasury's TARP Capital Purchase Program.

President and Chief Executive Officer Joseph J. Bouffard commented "We are
encouraged by the Company's continued profitability despite challenging
conditions within the financial services industry". He also noted that the
Bank's loan portfolio continues to demonstrate strong asset quality, with no
foreclosed real estate and a ratio of nonperforming assets to total assets of
only .32% as of March 31, 2009.

Stockholders' equity increased by $10.1 million during the six months ended
March 31, 2009. This increase is primarily due to the $10.8 million sale of
preferred stock in December 2008 related to the U.S. Treasury's TARP Capital
Purchase Program as well as earnings during the period. Stockholders' equity was
negatively impacted by accumulated other comprehensive loss (net of taxes) which
was ($3.5) million at March 31, 2009 compared to ($2.5) million as of September
30, 2008. Most of this loss relates to the Company's $24.0 million in
collateralized mortgage obligation securities portfolio, for which the gross

 2

market value declined by $4.4 million over the past six months. This is
reflective of turmoil in the mortgage backed securities market and the price
decline in market value of these securities. The Company has the ability and the
intent to hold these securities to maturity and to date, the securities have
performed in accordance with their terms. If in the future it is determined that
declines in market values or credit losses with respect to these or any other
securities are other than temporary, the Company would be required to recognize
losses in its consolidated statement of operations. The Company is currently
analyzing how the recent accounting guidance regarding the recognition of
other-than-temporary impairments may affect how these unrealized losses are
treated in the future.


                     PERIOD ENDING MARCH 31, 2009 HIGHLIGHTS


        o   The Company has reported six consecutive quarters of profitable
            operating results.

        o   Net interest income, interest rate spread and net interest margin
            for the three and six months ended March 31, 2009 increased in
            comparison to corresponding periods during the previous fiscal year.

        o   Deposits have increased by $10.4 million and $12.9 million over the
            three and six month periods ended March 31, 2009, respectively.

        o   The ratio of nonperforming assets to total assets remained very low
            at .32% as of March 31, 2009.
