SUFFOLK BANCORP ANNOUNCES EARNINGS FOR THE FIRST QUARTER OF 2009

Riverhead, New York, April 14, 2009 — Suffolk Bancorp (NASDAQ - SUBK) today released the results of its operations during the first quarter of 2009. Earnings-per-share were $0.59, a decrease of 25.3 percent from $0.79 during the comparable period of 2008. Net income was $5,659,000, down 25.1 percent from $7,559,000 during same quarter last year. However, earnings for the first quarter of 2008 included a non-recurring gain from the proceeds of the sale of shares of VISA, Inc. to the public on March 19, 2008. These shares had been acquired as a result of Suffolk’s membership in the VISA payments organization prior to the offering. The transaction added $2,429,000 to Suffolk’s net income during the first quarter of 2008, net of provision for income taxes, and amounted to $0.25 per share. Accordingly, to compare the quarter of 2009 to the prior comparable quarter of 2008, exclusive of the VISA transaction, earnings-per-share were $0.59, an increase of 9.3 percent from $0.54 during the comparable period of 2008. Net income was $5,659,000 up 10.3 percent from $5,130,000 during same quarter last year. A detailed financial summary follows the text.

President and Chief Executive Officer, J. Gordon Huszagh remarked, “The first quarter of 2009 has provided investors with a mix of economic information, both discouraging as in the case of employment, but also encouraging as in the example of the recent rally in equity markets. We cannot predict exactly where these developments will lead, but even in the face of this ongoing economic muddle, Suffolk Bancorp has been able to perform in a reasonably consistent fashion. The most meaningful way of comparing our performance this year to last is to set aside the VISA transaction, and to discuss our core performance. Without VISA, return on average equity increased to 19.63 percent from 18.62 percent last year. Return on average assets was similar at 1.39 percent, up one basis point from 1.38 percent in the first quarter of 2008. Our efficiency ratio improved slightly to 55.86 percent, down from 56.04 percent. Net interest income increased by 14.3 percent and our net interest margin improved to 4.97 percent from 4.78 percent as the yield curve developed a more normal slope and our cost of funds declined. These ratios are all in ranges that should be familiar to our shareholders.”

He continued, “Once again, as for the previous four quarters, we have been able to leverage most of our retained earnings, primarily through growth in average loan balances which increased by 12.3 percent from year to year as we continued to attract qualified and substantial borrowers who have come to us from larger banks that have lost significant capacity to lend as they were forced to take charges against their loans and investments. This is what is behind the increase in commercial mortgages and the considerable increase in real estate construction loans. As I have commented in previous quarters, as this portion of our loan portfolio has grown, these have been underwritten on the basis of reasonable ratios of loan-to-value, conservative evaluations of projected cash flows, and guarantees for permanent financing in place prior to granting an interim credit. We have also been successful in attracting new business as a residential lender, following again the same, basic principles in evaluating those credits. We believe these credits are the foundation of future banking relationships with steady customers who will contribute to Suffolk’s profitability for years to come.”

PRESS RELEASE April 14, 2009 Page 2 of 5

He added, “You will note that net charge-offs of loans amounted to a single basis point of average loans on an annualized basis. However, non-performing loans increased significantly to $8,380,000 from $4,884,000 last quarter, and $2,767,000 last year. In absolute terms, this is still a modest number at 76 basis points of net loans at March 31, 2009. Even so, I would like to provide you with an overview of the actual exposure that presents to Suffolk. Of the $8,380,000, $7,608,000 is secured by collateral currently valued at about $11,800,000 having a cumulative loan-to-value of approximately 65 percent. The unsecured portion of $772,000 amounts to only 7 basis points (7/10,000ths) of net loans at quarter end. As is our practice, we evaluate our allowance for possible loan losses continuously to ensure its sufficiency. Therefore, our provision has been increased by 333 percent over the same period in 2008 to provide for both growth in loans and our ongoing analysis of the portfolio. While we believe that we have been careful in underwriting these credits in the first place, we also believe that this is the sensible response to current circumstances, the outcome of which we humbly admit we cannot predict with any certainty.”

He went on to say, “In reviewing our quarterly income statement, there are a few things further that I would like to point out. Other operating expenses have increased by 22.5 percent from year to year for two main reasons. One is increased net assessments by the FDIC for deposit insurance made in response to the current unrest in the banking industry. This amounted to $424,000 in 2009 compared to $36,000 in 2008, an increase of 1,078 percent. The other is additional expense for the employee pension plan necessary after the value of plan assets declined during 2008 at the same time that the rate at which the future payments are discounted declined, resulting in a greater current liability. This amounted to $605,000 in 2009 compared to $255,000 in 2008, an increase of 137 percent. On the other hand, the provision for income taxes declined by 36.4 percent, primarily because of the VISA transaction last year.

Mr. Huszagh concluded his remarks by stating, “As we have been throughout the current economic downturn, we remain cautiously optimistic about Suffolk’s prospects. We make no assurances that we can or will maintain our traditional ratios of performance, but we are confident in our ability to maintain our rank in the industry. As always, we base the management of our company on a clear-eyed assessment of our situation, and a level-headed, realistic response based on regular, disciplined execution of our fundamental strategy. We have every reason to believe that it is in this direction that our success and our future lies.”
