PRESS RELEASE FOR IMMEDIATE RELEASE SEPTEMBER 25, 2007 For More Information Contact Joseph J. Bouffard (410) 248-9130 BCSB Bankcorp, Inc. BCSB BANKCORP, INC. PROVIDES EARNINGS GUIDANCE FOR THREE MONTHS ENDING SEPTEMBER 30, 2007 AND EXTENDS TERMINATION DATE OF STOCK OFFERING SEPTEMBER 25, 2007, BALTIMORE, MD - BCSB Bankcorp, Inc. (Nasdaq: BCSB) announced today earnings guidance for the three months ending September 30, 2007. In addition, BCSB Bancorp, Inc., the proposed holding company for Baltimore County Savings Bank, F.S.B. following the second step conversion and stock offering, announced today that it was extending the termination date for the subscription and community offering to 12:00 noon on October 19, 2007 and that it is extending the latest date to which it may extend this termination date without notice until December 3, 2007, unless the Office of Thrift Supervision approves a later date. Persons who have already submitted an order in the subscription and community offering will have the right to confirm, increase, decrease or rescind their orders to give prospective purchasers in the offering an opportunity to review the earnings guidance. EARNINGS GUIDANCE FOR THE THREE MONTHS ENDING SEPTEMBER 30, 2007 We anticipate that we will incur a net loss for the three months ending September 30, 2007. Our expectation of a net loss is based on an anticipated reduction in net interest income compared to the three months ended June 30, 2007, as well as certain expenses we expect to incur in the three months ending September 30, 2007. Net interest income is expected to decrease by approximately $190,000 during the three months ending September 30, 2007 compared to the three months ended June 30, 2007. Of this amount, $50,000 represents the effect of accelerated repayments by borrowers within the indirect lending portfolio. The remaining decrease reflects the higher cost of special certificate of deposit products recently introduced to attract new customers. During the three months ending September 30, 2007, salaries and related expense is expected to include a pre-tax expense of approximately $80,000 in connection with our policy to pay employees for unused sick leave and vacation pay. Effective October 1, 2007 this policy will be changed to eliminate this expense in future periods. In addition, we expect to incur approximately $150,000 on a pre-tax basis related to an agreement we entered into in connection with the retirement of William M. Loughran, our Executive Vice President and Chief Lending Officer. Under this agreement, Mr. Loughran, who is retiring after 34 years of service with us, will receive the equivalent of one year's salary and benefits and will remain as a director. Professional fees for the three months ending September 30, 2007 are expected to include increased fees, relative to the three months ended June 30, 2007, for consulting and legal services totaling approximately $150,000 on a pre-tax basis. These fees relate to special, limited scope consulting and legal projects that have been completed. We continue to aggressively pursue further collection of losses sustained as a result of the check kiting scheme previously reported and will expense an additional $296,000 on a pre-tax basis in connection with pursuing and defending various claims in the bankruptcy estate of the former customer and with other litigants with competing claims seeking to recover limited available assets. We feel it is prudent to recognize this expense at this time in light of the complex and protracted nature of the ongoing proceeding. At this time, we do not believe, however, that we will incur additional material expenses in connection with this matter. Other expenses also are expected to include an expense of approximately $200,000 on a pre-tax basis for Federal Deposit Insurance Corporation insurance premiums due to a new premium assessment methodology applicable in 2007. As a result of the above items, we anticipate that we will incur net after tax losses totaling between approximately $300,000 and $350,000 during the three months ending September 30, 2007.
