SUFFOLK BANCORP REPORTS RESULTS FOR THE SECOND QUARTER OF 2012

June 2012 non-performing assets decline by 25% versus first quarter 2012

Net income increases by 28% versus 2011

Core deposits increase to 81% of total funding. Demand deposits increase by 9% versus 2011

Net interest margin remains strong at 4.39%. Average cost of funds declines to 0.29% in 2012

Riverhead, New York, July 30, 2012 — Suffolk Bancorp (the “Company”) (NASDAQ - SUBK), parent company of Suffolk County National Bank (the “Bank”), today reported second quarter 2012 net income of $4.2 million, or $0.43 per diluted common share, compared to net income of $3.3 million, or $0.34 per diluted common share, a year ago. For the six-month period ended June 30, 2012, the Company recorded net income of $5.4 million, or $0.55 per diluted common share, compared with a net loss of $4.3 million, or ($0.44) per diluted common share, in the June 2011 year-to-date period.

The improvement in second quarter earnings in 2012 was primarily the result of a $5.6 million reduction in the provision for loan losses, which includes a $2.4 million credit to the provision in 2012, and an $891 thousand (5.9%) decrease in total operating expenses. The decrease in the provision for loan losses resulted from a significant reduction in the level of criticized and classified assets in 2012 coupled with continued positive results from ongoing workout and non-performing asset disposition activities. Partially offsetting the foregoing improvements was a $3.0 million (16.8%) contraction in net interest income and a $1.7 million (41.5%) decrease in total non-interest income in 2012 versus 2011.

The reduction in operating expenses in 2012 resulted from a non-recurring $1.0 million pre-payment fee incurred on the termination of a Federal Home Loan Bank borrowing during the second quarter of 2011 coupled with a lower level of consulting expenses incurred in 2012. Partially offsetting this improvement was a decrease in non-interest income largely due to a $1.6 million reduction in net gains on the sales of securities available for sale in 2012. The reduction in net interest income resulted from a lower level of average interest-earning assets, primarily loans, coupled with a narrowing of the net interest margin in 2012 when compared to the same period a year ago. The decrease in the net interest margin was due to the continued low level of interest rates, a shift in the Company’s balance sheet mix from loans into lower-yielding overnight interest-bearing deposits, due principally to ongoing loan workout activity, and the level of non-accrual loans still present in 2012.

Commenting on the second quarter results, President and CEO Howard C. Bluver stated, “I am extremely pleased with the progress we made during the second quarter in cleaning up our balance sheet. As I have stated in the past, among my highest priorities upon being appointed CEO seven months ago was to recruit a top notch executive management team and to implement aggressive credit remediation steps. With the new executive team fully in place, we were able to make significant progress this quarter in reducing our levels of both non-performing loans and our criticized and classified loan book.

I note in this regard that total non-performing assets were reduced by 25% from $85 million at March 31, 2012 to $64 million at the end of the second quarter. This reduction results from loans that were sold in the quarter, and still includes $7.5 million in non-performing loans that were reclassified as held-for-sale that are subject to a definitive sales agreement with an anticipated August 2012 closing. These positive results were achieved via very focused and aggressive workout activities, including working with existing borrowers where warranted, and selling or contracting to sell loans either individually or in bulk on attractive terms. During the quarter, we sold or transferred loans to held-for-sale at an aggregate price of 77% of book value, resulting in a $7.0 million charge to the allowance for loan losses. Similarly, we were able to achieve accelerated improvement in our total criticized and classified loan levels during the quarter, from $247 million at the end of the first quarter 2012 to $175 million at June 30, 2012.

I am very pleased that we were able to execute these improvements in our key credit metrics while maintaining both strong capital ratios and a healthy allowance for loan losses. With our critical staff complete and in place, we will continue to implement aggressive

credit remediation strategies throughout 2012, and expect to see additional improvements in our key credit metrics as the year moves on.

I also want to emphasize that our core deposit franchise continues to be among the best in the region and performed very well in the second quarter. Over 80% of our total deposits are in low cost, stable core deposit products, including over 40% in demand deposit accounts. This product mix continues to be a primary strength of our Company, and resulted in a total cost of funds of approximately 29 basis points during the second quarter and a net interest margin of 4.39%. As we continue our aggressive efforts to put the legacy asset issues behind us, we will never lose sight of the fact that our core deposit franchise is the single most important competitive advantage we have.

Once we have completed the work of cleaning up our balance sheet, I believe that our strong management team, superior deposit franchise and attractive market area will yield improved financial results in the coming quarters.”

This press release includes a non-GAAP financial measure of the Company’s tangible common equity ratio. A non-GAAP financial measure is a numerical measure of historical or future financial performance, financial position or cash flows that excludes or includes amounts that are required to be disclosed by generally accepted accounting principles in the United States (GAAP). The Company believes that this non-GAAP financial measure provides both management and investors a more complete understanding of the underlying operational results and trends and the Company’s marketplace performance.

Safe Harbor Statement Pursuant to the Private Securities Litigation Reform Act of 1995

This press release includes statements which look to the future. These can include remarks about the Company, the banking industry, the economy in general, expectations of the business environment in which the Company operates, projections of future performance, and potential future credit experience. These remarks are based upon current management expectations, and may, therefore, involve risks and uncertainties that cannot be predicted or quantified and are beyond the Company’s control and are subject to a variety of uncertainties that could cause future results to vary materially from the Company’s historical performance, or from current expectations. These remarks may be identified by such forward-looking statements as “should,” “expect,” “believe,” “view,” “opportunity,” “allow,” “continues,” “reflects,” “typically,” “usually,” “anticipate,” or similar statements or variations of such terms. Factors that could affect the Company include particularly, but are not limited to: a failure by the Company to meet the deadlines under SEC rules for filing its periodic reports (or any permitted extension thereof); changes in interest rates; increases or decreases in retail and commercial economic activity in the Company’s market area; variations in the ability and propensity of consumers and businesses to borrow, repay, or deposit money, or to use other banking and financial services; results of regulatory examinations; any failure by the Company to comply with our written agreement with the OCC (the “Agreement”) or the individual minimum capital ratios for the Bank established by the OCC; the cost of compliance with the Agreement; any failure by the Company to maintain effective internal controls over financial reporting; larger-than-expected losses from the sale of assets; potential litigation or regulatory action relating to the matters resulting in the Company’s failure to file on time its Quarterly Report on Form 10-Q for the quarters ended March 31, 2011, June 30, 2011, and September 30, 2011 or resulting from the revisions to earnings previously announced on April 12, 2011 or the restatement of its financial statements for the quarterly period ended September 30, 2010 and year ended December 31, 2010; and the potential that net charge-offs are higher than expected or for further increases in our provision for loan losses. Further, it could take the Company longer than anticipated to implement its strategic plans to increase revenue and manage non-interest expense, or it may not be possible to implement those plans at all. Finally, new and unanticipated legislation, regulation, or accounting standards may require the Company to change its practices in ways that materially change the results of operations. We have no obligation to update any forward-looking statements to reflect events or circumstances after the date of this document.
