EXHIBIT 99.1 CONTACT: James R. Rice, Senior Vice President (508) 984-6102 FOR IMMEDIATE RELEASE SEACOAST FINANCIAL SERVICES CORPORATION RESERVES FOR POTENTIAL STATE TAX LIABILITY March 6, 2003 -- New Bedford, MA - Seacoast Financial Services Corporation (Nasdaq: SCFS), holding company for CompassBank and Nantucket Bank, announced today that it will record a provision in the first quarter of 2003 of approximately $11.2 million, representing an estimate of the additional state tax liability, including interest (net of any federal or state tax deduction associated with such taxes and interest), relating to the deduction for dividends received by Compass Bank and Nantucket Bank from their real estate investment trust subsidiaries (REITs) for the 1999 through 2002 fiscal years, thus reducing earnings for the first quarter of 2003 by that amount. The provision relates to new legislation signed on March 5, 2003 by the Governor of Massachusetts that amends Massachusetts law to expressly disallow the deduction for dividends received from a REIT. This amendment applies retroactively to tax years ending on or after December 31, 1999. Although Seacoast Financial questions the constitutionality of this retroactive legislation, accounting principles generally accepted in the United States dictate that the total estimated assessment, including interest, be provided for at the time the law is enacted. Accordingly, Seacoast Financial will record this accrued liability. In addition, as a result of the new legislation, Seacoast Financial will also cease recording the tax benefits associated with the dividend received deduction, effective for the 2003 tax year. This loss of deduction, impacting both CompassBank and Nantucket Bank REITs, is expected to result in a reduction in the consolidated net income in 2003 of approximately $3.1 million or $0.14 per diluted share. Seacoast Financial believes that this new legislation would apply to numerous financial institutions in Massachusetts and that it will be challenged, especially the retroactive provisions, on constitutional and other grounds. Seacoast Financial would support such a challenge and otherwise intends to vigorously defend its position.
