Exhibit 99.1 FIRST NIAGARA FINANCIAL GROUP, INC. REPORTS COMMON STOCK REPURCHASE PROGRAM Lockport, N.Y. - July 24, 2003 - First Niagara Financial Group, Inc. (NASDAQ: FNFG), today announced that it has received a regulatory non-objection from the Office of Thrift Supervision to its request to repurchase up to 2.1 million (3%) of its outstanding common stock in order to fund currently exercisable stock options. The regulatory non-objection was necessary because the repurchase program will commence less than one year from the date of the Company's reorganization and second step stock offering, which closed January 17, 2003. Management of the Company will use its discretion in determining the timing of the repurchases and the prices at which repurchases will be made. The extent to which shares are repurchased will depend on a number of factors including market trends and prices, economic conditions, alternative uses for capital and the strength of the Company's capital in relation to its activities. First Niagara Financial Group, Inc., through its wholly owned subsidiary First Niagara Bank, has assets of $3.6 billion and deposits of $2.4 billion. First Niagara Bank is a full-service, community-oriented bank that provides financial services to individuals, families and businesses through 46 banking centers, a loan production office, several financial services subsidiaries, and 84 ATMs throughout upstate New York.
