SUFFOLK BANCORP ANNOUNCES EARNINGS FOR THE FOURTH QUARTER AND THE FULL YEAR OF 2007

Riverhead, New York, January 15, 2008 — Suffolk Bancorp (NASDAQ - SUBK) today released the results of its operations during the fourth quarter and full year of 2007. Earnings-per-share for the quarter were $0.58, an increase of 5.5 percent from $0.55 during the comparable period of 2006. Net income for the quarter was $5,604,000, up 0.1 percent from the same quarter last year. Earnings-per-share for the year to date were $2.24, an increase of 1.8 percent from $2.20 during the comparable period of 2006. Net income for the year was $22,128,000, down 2.2 percent from the same period last year. A detailed financial summary follows the text of this release.

Chairman, President, and Chief Executive Officer, Thomas S. Kohlmann, remarked, “It is gratifying to have encouraging news to report for a period of time when financial markets were so unpredictable. We were able to increase earnings per share over 2006 for both the fourth quarter and full year. Return on average equity remained in excess of 21 percent for the quarter and the year. Our average loan portfolio grew moderately from the same quarter last year, by a bit more than six percent. As liquidity contracted both domestically and globally as a result of recent losses in the sub-prime mortgage markets, deposits were flat and there was migration from non-maturity time deposits to higher yielding certificates of deposit. Average borrowings increased, resulting in a substantial increase in interest expense and small declines in net interest income and margin for the quarter and the year. While the provision for possible loan losses was increased during the fourth quarter to reflect our historic methodology in computing the allowance, it was down 61 percent for the year, and we were able to post net recoveries for both the quarter and the year. Non interest income increased modestly for the quarter, and was essentially flat for the year. We kept a tight rein on non-interest expense, which was actually down by 2.3 percent for the quarter, and up 1.0 percent for the year while average assets increased by 1.8 percent for the quarter and 0.3 percent for the year. Finally, we managed capital to the regulatory standard of ‘well-capitalized,’ while also maximizing profitability for our shareholders. The biggest challenges in the past quarter remained in funding our operations, as major players in worldwide markets have bid up the price of funds as they wrote down a significant portion of their investments in mortgages and mortgage-backed securities, as well as other exotic financial instruments.”

He continued, “If these remarks sound familiar to those I have made in the past, they are and should be. Banking is an incremental business, built on margins. Achievement in this industry is based on a disciplined and careful approach to maintaining those margins. We build our balance sheet one, carefully underwritten loan at a time; one, thoughtfully considered security at a time; and one, correctly priced deposit at a time. Key is the ability to adhere to consistent and well-considered standards, in both boom times and in times like these. The true value in our business lies in the relationships we build with our customers over months and years. There are no sudden pops or sizzle at a well-run bank, just a steady accumulation of value based on the time value of money over the long-run. Success lies in doing a great number of small things well while avoiding major mistakes. As an example, once again, I would like to remind investors that we avoided the temptation of the sub-prime market altogether, both by maintaining our standards in the loans we make directly, and by investing in collateralized mortgage obligations the quality and structure of which we have evaluated as carefully as we underwrite our loans. We want to preserve our place among the higher performing banks in the nation.”

Mr. Kohlmann finished saying, “2008 will be a difficult year as financial markets and the economy in general sort themselves out. We are ready, clearly and sharply focused on our shareholders’, customers’, and employees’ common interests, today, tomorrow, and in the years to come.”
