Exhibit 99 [LETTERHEAD] CONTACT: Gary S. Paul FOR IMMEDIATE RELEASE: (716) 842-5130 January 9, 1998 BUFFALO, NEW YORK -- First Empire State Corporation ("First Empire") (AMEX: FES) today reported diluted earnings per share of $25.26 in 1997, an increase of 20% from $21.08 in 1996. Net income for 1997 rose 17% to $176.2 million from $151.1 million in 1996. For the fourth quarter of 1997, diluted earnings per common share increased 17% to $6.66 from $5.70 earned in the year-earlier quarter. Net income in the recently completed quarter was $46.3 million, an increase of 15% from $40.4 million earned in the final quarter of 1996. All earnings per share amounts reflect the implementation of Statement of Financial Accounting Standards ("SFAS") No. 128, "Earnings Per Share." SFAS No. 128 establishes new standards for computing and presenting earnings per share and is effective for financial statements for both interim and annual periods ending after December 15, 1997. SFAS No. 128 requires that all prior period earnings per share data be restated to conform with the provisions of the statement. Taxable-equivalent net interest income increased 5% to $562.7 million in 1997 from $535.5 million in 1996. Average loans outstanding totaled $11.0 billion in 1997, an 8% increase from $10.1 billion in 1996. The beneficial impact on net interest income of growth in loans exceeded the effect of a narrowing of the spread between yields on earning assets and -more- 2-2-2-2-2 FIRST EMPIRE STATE CORPORATION rates paid on interest-bearing liabilities. As a result of such narrowing, net interest margin, or taxable-equivalent net interest income expressed as a percentage of average earning assets, was 4.38% in 1997 compared with 4.45% in 1996. The provision for possible credit losses was $46.0 million in 1997, compared with $43.3 million in 1996. Net charge-offs for 1997 were $41.8 million or .38% of average loans, compared with $35.2 million or .35% in the prior year. Consumer loan net charge-offs for the recent year were $35.9 million, compared with $28.5 million in 1996. The allowance for possible credit losses was $274.7 million or 2.39% of loans outstanding at December 31, 1997, compared with $270.5 million or 2.52% at the prior year-end. Nonperforming loans totaled $80.7 million at December 31, 1997, compared with $97.9 million at December 31, 1996. The ratio of the allowance to nonperforming loans was 341% and 276% at December 31, 1997 and 1996, respectively. Assets taken in foreclosure of defaulted loans were $8.4 million and $8.5 million at the end of 1997 and 1996, respectively. Other income rose 13% to $193.1 million in 1997 from $170.2 million in 1996. Higher revenues associated with mortgage banking and trust activities contributed to this increase. Other expense was $421.8 million in 1997, up 3% from $409.0 million in 1996. Included in other expense for 1996 was a $7.0 million charge for a special assessment by the Federal Deposit Insurance Corporation -more- 3-3-3-3-3 FIRST EMPIRE STATE CORPORATION to recapitalize the Savings Association Insurance Fund. The rates of return on average total assets and average common stockholders' equity in 1997 were 1.32% and 18.49%, respectively, compared with 1.21% and 17.60% in 1996. At December 31, 1997, First Empire had total assets of $14.0 billion, compared with $12.9 billion a year earlier. Loans and leases, net of unearned discount, were $11.5 billion at the end of 1997, up from $10.7 billion at December 31, 1996. Deposits were $11.2 billion and $10.5 billion at December 31, 1997 and 1996, respectively. Total common stockholders' equity was $1.0 billion or 7.36% of total assets at year-end 1997, compared with $906 million or 7.00% a year earlier. Common stockholders' equity per share was $155.86 at the recent year-end and $135.45 at December 31, 1996. As previously announced, in October 1997 First Empire entered into a definitive agreement with ONBANCorp, Inc., Syracuse, New York, for a merger between the two companies. The merger is subject to the approval of stockholders of both companies, as well as various regulatory agencies, and is expected to be completed in the first quarter of 1998. In February 1997, First Empire announced a plan to repurchase up to 303,317 shares of its common stock for -more- 4-4-4-4-4 FIRST EMPIRE STATE CORPORATION reissuance upon the possible future exercise of outstanding stock options. As of December 31, 1997, First Empire had repurchased 178,011 common shares pursuant to such plan at an average cost of $331.78. First Empire is a bank holding company with subsidiaries that include Manufacturers and Traders Trust Company (Buffalo, New York) and M&T Bank, National Association (Oakfield, New York). -more- 5-5-5-5-5 FIRST EMPIRE STATE CORPORATION Condensed Consolidated Statement of Income THREE MONTHS ENDED TWELVE MONTHS ENDED DECEMBER 31 DECEMBER 31 AMOUNTS IN THOUSANDS, --------------------- --------------------- EXCEPT PER SHARE 1997 1996 CHANGE 1997 1996 CHANGE -
