1 Exhibit 99.1 NEWS RELEASE Contact: Paul S. Feeley For Release: Immediately Senior Vice President, Treasurer & Chief Financial Officer (617) 628-4000 CENTRAL BANCORP REPORTS QUARTERLY EARNINGS SOMERVILLE, MASSACHUSETTS, October 31, 2006 - Central Bancorp, Inc. (NASDAQ Global MarketSM:CEBK) today reported that its net income for the quarter ended September 30, 2006 was $351,000, or $0.24 per diluted share, compared to net income of $624,000, or $0.43 per diluted share, for the corresponding 2005 quarter. The Company's earnings for the six-month periods ended September 30, 2006 and September 30, 2005 were $464,000, or $0.32 per diluted share, and $1.3 million, or $0.93 per diluted share, respectively. The decrease in net income in the 2006 quarter compared to the 2005 quarter primarily resulted from decreases of $338,000 in net interest and dividend income and $159,000 in non-interest income, partially offset by lower non-interest expenses and the absence of a loan loss provision for the quarter ended September 30, 2006. Net interest and dividend income continued to be adversely affected by the continuing flat to inverted yield curve as well as strong local competition for the products and services we offer. Decreases occurred in the net interest spread and the net interest margin from 2.82% and 3.22%, respectively, for the 2005 quarter to 2.42% and 2.91%, respectively, for the 2006 quarter. These decreases in the spread and margin were primarily due to increases in both the volume of and the rates paid on interest-bearing liabilities. While the yield on interest-earning assets rose by 42 basis points, the cost of funds increased by 82 basis points. Interest-bearing liabilities continued to re-price upward faster than interest-earning assets, primarily due to the combined effect of an increase in short-term interest rates over the comparable period last year and continued strong competition for (CONTINUED) 2 CENTRAL BANCORP, INC. PAGE 2 OF 4 both deposits and loans in our market. The decrease in net interest and dividend income was partially offset during the current quarter by the receipt of $199,000 from the Federal Home Loan Bank, which represented a normalized dividend for the past two quarters. Management did not record a provision for loan losses in the 2006 quarter compared to a $50,000 provision in the 2005 quarter because it believes the allowance was sufficient at September 30, 2006. Non-interest expenses declined $18,000, mainly reflecting the absence of non-recurring restructuring costs of $283,000 for voluntary termination packages offered during the 2005 quarter that were partially offset by salary and benefit increases, additional staff at our new Medford branch office, and rent, utilities and equipment at the new branch and operations center. Income tax expense for the September 2006 quarter decreased $156,000 from the 2005 quarter due to lower pre-tax income. The decrease in net income for the six months ended September 30, 2006 compared to the corresponding year-earlier period primarily resulted from decreases of $919,000 in net interest and dividend income and $163,000 in non-interest income, and a $314,000 increase in non-interest expenses. The decrease in net interest and dividend income reflected the combined effect of a lower net interest spread and net interest margin. Decreases occurred in the net interest spread and the net interest margin from 2.85% and 3.22%, respectively, for the 2005 six-month period to 2.38% and 2.82%, respectively, for the 2006 comparable period. While the cost of funds increased by 68 basis points, the yield on interest-earning assets increased by 21 basis points. (CONTINUED) 3 CENTRAL BANCORP, INC. PAGE 3 OF 4 The increase in non-interest expenses for the six months ended September 30, 2006 was primarily attributable to the higher expenses discussed above, partially offset by the absence of the non-recurring restructuring costs in 2005 also discussed above. The provisions for loan losses were $50,000 and $100,000, respectively, for the six months ended September 30, 2006 and September 30, 2005. Lower pre-tax income caused income tax expense for the six months ended September 30, 2006 to decrease $480,000 from the corresponding 2005 period. Total assets were $556.1 million at September 30, 2006 and $547.3 million at March 31, 2006. During the six months ended September 30, 2006, investment securities available for sale decreased by $5.6 million as the result of maturities and pay-downs of investments and the mandatory redemption of a portion of our investment in FHLB stock. During this same period, loans increased by $19.3 million, from $415.4 million to $434.7 million due to our continued focus on originating commercial real estate and construction loans as well as the purchase and origination of residential real estate loans. As deposits declined by $4.7 million, borrowings increased by $12.8 million as we temporarily discontinued advertising premium rates on certificates of deposit during the 2006 period, instead electing to utilize more cost-effective FHLB advances to fund loan growth.
