SUFFOLK BANCORP ANNOUNCES THIRD QUARTER EARNINGS

Riverhead, New York, October 15, 2004 — Suffolk Bancorp (NASDAQ - SUBK) today released the results of its operations during the third quarter of 2004. Net income for the quarter was $5,207,000, off 3.0 percent from $5,367,000 posted during the same period last year. Earnings-per-share for the quarter were $0.48, down from $0.49 in the comparable period of 2003. Net income for the year to date was $15,104,000, a decline of 4.6 percent from $15,837,000 posted during the same period last year. Earnings-per-share for the year to date were $1.39 compared to $1.43, down 2.8 percent. A detailed financial summary follows the text of this release.

President and Chief Executive Officer, Thomas S. Kohlmann, remarked, “There are two key points to understanding Suffolk’s performance during the past quarter in comparison to the previous year. The first is the continued compression of margin as a result of historically low interest rates, reflected in our net interest margin which declined by 12 basis points from the same quarter last year. As an asset-sensitive bank, where our loans and investments reprice upward faster than our funding, we are heartened by cumulative increases of 75 basis points in the Federal Funds rate, and we look forward to its contribution to our margin. The second point is a substantial decline in balances of indirect automobile loans year to year, a development we had anticipated and planned for during the past several years as the captive finance companies of major automobile manufacturers have used loan incentive programs to generate sales. All other categories of loans as a group, including commercial, commercial real estate, construction, and home equity loans grew by 10.3 percent from the prior year, and demonstrate Suffolk’s capacity to offset indirect loan runoff in the short and intermediate term, and to expand the portfolio in the long run. Variances from the prior period in various measures of asset-quality continue to stem primarily from a single credit now in workout, and which was disclosed in a previous earnings release.”

He went on to say, “Our funding mix continues to improve with demand balances, and less expensive non-maturity time deposits increasing by 4.6 and 3.9 percent respectively, while more expensive time certificates of $100,000 or more and other time deposits have declined by 17.3 and 12.9 percent, leaving deposit balances approximately the same. The main factor influencing non-interest income in comparison to the same period of 2003 is a securities gain in the third quarter of 2003 when interest rates warranted, not repeated in this quarter as Suffolk sells securities primarily to reposition the portfolio for better long-term performance, and not for short-term gain. Non-interest expense was again managed tightly, resulting in a 30 basis point reduction from the prior year.”

Mr. Kohlmann concluded, “Our balance sheet is actually better diversified than it has been in the past, with a variety of sources of revenue, and modestly priced funding. We look forward to taking advantage of this base to build our relationships with both commercial customers and retail consumers in branch offices throughout Suffolk County, New York.”
