Suffolk Bancorp (the “Company”) (NYSE:SCNB), parent company of Suffolk County National Bank (the “Bank”), today reported net income of $3.7 million, or $0.31 per diluted common share, for the fourth quarter of 2016 compared to $3.6 million, or $0.31 per diluted common share, a year ago. For the year ended December 31, 2016, the Company recorded net income of $19.8 million, or $1.66 per diluted common share, versus $17.7 million, or $1.49 per diluted common share for the comparable 2015 full year period. Excluding merger-related charges, net non-accrual interest received and other real estate owned (“OREO”) expenses incurred in 2016, core net income was $5.0 million and $21.5 million in the fourth quarter and full year 2016 periods, respectively.

The 2.6% increase in fourth quarter 2016 earnings versus the comparable 2015 period resulted from a $239 thousand increase in net interest income and a $400 thousand reduction in the provision for loan losses. Based upon consideration of many factors, including credit risk grades and economic conditions, in its evaluation of the various classes of the loan portfolio, the Company recorded in total a $400 thousand credit to the provision for loan losses in the fourth quarter of 2016. No provision expense was recorded in the comparable 2015 period. Partially offsetting these improvements was a $378 thousand increase in total operating expenses in 2016 when compared to the fourth quarter of 2015.

The Company is also pleased that the Office of the Comptroller of the Currency has approved the merger of the Bank with People's United Bank, N.A., the bank subsidiary of People's United Financial, Inc., in connection with the previously announced merger of the Company and People's United Financial, Inc. The merger transaction, which was previously approved by the Company's shareholders, remains subject to the approval of the Board of Governors of the Federal Reserve System and other customary conditions to closing, and is currently expected to be completed during the first quarter.

President & CEO Howard C. Bluver stated: “I am pleased to report a strong fourth quarter. Most importantly, we made significant progress during the quarter toward ensuring a smooth and successful integration in connection with our pending merger with People’s United Financial. When the merger was announced on June 27, 2016, I stated my belief that we could leverage the strengths of our combined institutions for the benefit of all our current and future stakeholders. After seeing how closely and cooperatively our respective teams have worked together over the past seven months, I am even more confident today that we will hit the ground running on day one. It is also gratifying to see that our continued Company-wide focus on high quality execution has not been compromised as a result of the pending merger.

“First, our deposit businesses performed well during the quarter. While linked-quarter commercial and municipal deposit levels reflect the winter seasonality that is inherent in many of our markets, particularly in the Hamptons on the east end of Long Island, we continue to grow deposit levels year over year, particularly with respect to non-interest bearing demand deposits. Total non-interest bearing demand deposits at December 31, 2016 were $867 million, compared to $788 million at December 31, 2015, an increase of $79 million, or 10.1%. At the end of 2016, 47% of our total deposits were demand deposits, resulting in an extraordinarily low cost of funds of 18 basis points during the fourth quarter and an attractive net interest margin of 3.68% for the quarter.

“Second, we experienced modest loan growth in 2016 compared to 2015, which is not surprising given our previously announced decision to temporarily pull back from certain commercial lending markets during the middle of the year. In addition, we sold $77 million in multi-family loans during the year, including approximately $28 million during the fourth quarter, in order to generate non-interest income, protect our net interest margin and avoid becoming too concentrated in a single product line. Notwithstanding these factors, I am pleased to report that we are building a very strong and diversified loan pipeline for the future and, once the merger with People’s United closes, we will no longer be subject to the growth constraints that come from operating with a relatively small balance sheet.

“Finally, credit quality continues to be strong in all categories. Total non-accrual loans at December 31, 2016 were $5.6 million, or 0.33% of total loans, compared to $6.3 million, or 0.37% of total loans, at September 30, 2016. All other key credit metrics remain solid and reflect our steadfast commitment to a strong and highly disciplined credit culture. Early delinquencies (30-89 days past due), which we manage aggressively as a harbinger of future credit issues, remain extremely low at $1.2 million, or 0.07% of total loans, at December 31, 2016, compared to $2.0 million, or 0.12% of total loans, at September 30, 2016. Given the continuous improvement we have seen in our credit profile, we also believe we are well reserved. Our allowance for loan losses at December 31, 2016 was $20.1 million, or 1.20% of total loans and 362% of total non-accrual loans.”

Earnings Summary for the Quarter Ended December 31, 2016

The Company recorded net income of $3.7 million during the fourth quarter of 2016 versus $3.6 million in the comparable quarter a year ago. Excluding merger-related charges, net non-accrual interest received and OREO expenses incurred, core net income was $5.0 million in the fourth quarter of 2016. The 2.6% improvement in reported fourth quarter 2016 net income versus the comparable 2015 period resulted from a $239 thousand increase in net interest income and a $400 thousand reduction in the provision for loan losses. The Company recorded a $400 thousand credit to the provision for loan losses in the fourth quarter of 2016. Partially offsetting these positive factors was a $378 thousand increase in total operating expenses in the fourth quarter of 2016 versus 2015. The Company’s effective tax rate was 26.8% in the fourth quarter of 2016 versus 24.8% a year ago.

The $239 thousand or 1.3% improvement in fourth quarter 2016 net interest income resulted from a $101 million (5.3%) increase in average total interest-earning assets. Partially offsetting the earning asset growth was a 16 basis point decline in the Company’s net interest margin to 3.68% in 2016 from 3.84% in 2015. The Company’s fourth quarter 2016 average total interest-earning asset yield was 3.85% versus 4.05% in the comparable 2015 quarterly period. The decrease in the interest-earning asset yield in 2016 resulted from a two basis point decline in the average loan yield to 4.15% in 2016 along with a shift in the average asset mix to a greater percentage of Fed funds sold, securities purchased under agreements to resell and interest-bearing deposits due from banks (short-term investments) in 2016. Average loans increased by $95 million (6.0%) versus fourth quarter 2015. The average securities portfolio decreased by $107 million to $204 million in the fourth quarter of 2016 versus the comparable 2015 period. The average yield on the investment portfolio was 3.54% in 2016 versus 3.62% a year ago.

Average short-term investments grew by $115 million in 2016 at an average yield of 0.49%.

The Company’s average cost of total interest-bearing liabilities decreased by four basis points to 0.33% in the fourth quarter of 2016 versus 0.37% in the comparable 2015 quarter. The Company’s total cost of funds, among the lowest in the industry, was 0.18% in the fourth quarter of 2016 versus 0.21% a year ago. Average core deposits increased $146 million (9.3%) to $1.7 billion during the fourth quarter of 2016 versus the fourth quarter of 2015, with average demand deposits representing 46% of fourth quarter 2016 average total deposits. Total deposits increased by $58 million or 3.2% to $1.8 billion at December 31, 2016 versus the comparable 2015 date.

Total borrowings at December 31, 2016 were $15 million versus $165 million at the comparable 2015 date.

Non-interest income was unchanged in the fourth quarter of 2016 versus the comparable 2015 period. A reduction in service charges on deposit accounts (down $187 thousand) was offset by increases in other service charges, commissions and fees (up $117 thousand) and net gain on sale of securities available for sale (up $70 thousand).

Total operating expenses increased by $378 thousand or 2.5% in the fourth quarter of 2016 versus 2015 principally the result of $1.8 million of merger-related expenses incurred in 2016. Excluding these merger-related costs and $1.4 million in systems conversion expenses recorded in the fourth quarter of 2015, core operating expenses increased by $31 thousand or 0.2% in 2016 when compared to the fourth quarter of 2015. Growth in employee compensation and benefits of $1.0 million was the primary reason for the nominal increase in core operating expenses in 2016. Partially offsetting this increase were reductions in 2016 in other operating expenses, data processing costs and FDIC assessment expenses of $328 thousand, $291 thousand and $214 thousand, respectively, versus the comparable 2015 period. Consulting and professional fees were also lower by $118 thousand in the fourth quarter of 2016 from the year ago period. The increase in employee compensation and benefits expense in 2016 resulted principally from an increase in incentive compensation expense coupled with a higher deferred expense credit in 2015 due to last year’s increased fourth quarter loan production. The improvement in data processing costs resulted from lower core systems expenses in 2016 resulting from the conversion to Fiserv in the second quarter of 2016. The Company’s operating efficiency ratio was 73.6% in the fourth quarter of 2016 versus 71.9% a year ago.

The Company recorded income tax expense of $1.4 million in the fourth quarter of 2016 resulting in an effective tax rate of 26.8% versus an income tax expense of $1.2 million and an effective tax rate of 24.8% in the comparable period a year ago.

Earnings Summary for the Year Ended December 31, 2016

Excluding merger-related charges, net non-accrual interest received and OREO expenses incurred, core net income was $21.5 million for the full year of 2016. The improvement in reported 2016 net income resulted principally from a $4.3 million increase in net interest income coupled with a $1.1 million reduction in the provision for loan losses. Partially offsetting these positive factors was a $1.4 million increase in total operating expenses, a $111 thousand reduction in non-interest income, and an increase in the Company’s effective tax rate in 2016. Excluding merger-related expenses incurred in 2016 and systems conversion expenses incurred in 2015, total operating expenses increased by $375 thousand or 0.7% versus 2015.

The $4.3 million or 6.1% improvement in full year 2016 net interest income resulted from a $201 million increase in average total interest-earning assets, offset in part by a 21 basis point contraction of the Company’s net interest margin to 3.77% in 2016 from 3.98% in 2015. The Company’s full year 2016 average total interest-earning asset yield was 3.96% versus 4.15% in the comparable 2015 period. A lower average yield on the Company’s loan portfolio in 2016 versus the comparable 2015 period, down 13 basis points to 4.17%, was the primary driver of the reduction in the interest-earning asset yield. Excluding the impact of net non-accrual interest received in each full year period, the Company’s core net interest margin was 3.71% in 2016 versus 3.91% in 2015.

Total operating expenses increased by $1.4 million (2.5%) in the full year 2016 versus 2015 principally due to $2.4 million in merger-related expenses coupled with growth in employee compensation and benefits expense (up $1.6 million), offset in part by reductions in non-recurring project costs (systems conversion expenses) and data processing costs of $1.4 million and $1.3 million, respectively. The Company’s operating efficiency ratio improved to 64.5% in 2016 from 65.6% a year ago.

Factors that could affect the Company include particularly, but are not limited to: the ability to obtain regulatory approvals and meet other closing conditions to the merger with People’s United, including the risk that regulatory approvals required for the merger are not obtained or are obtained subject to conditions that are not anticipated; delay in closing the merger; difficulties and delays in integrating the Company’s business or fully realizing cost savings and other benefits of the merger; business disruption following the merger; increased capital requirements mandated by the Company’s regulators, including the individual minimum capital requirements that the OCC established for the Bank; the Bank’s temporary limitation on the growth of its commercial real estate (“CRE”) portfolio and the potentially adverse impact thereof on the Company’s overall business, financial condition and results of operation due to the importance of the Bank’s CRE business to the Company’s overall business, financial condition and results of operation; any failure by the Bank to comply with the individual minimum capital ratios (including as a result of increases to the Bank’s allowance for loan losses), which may result in regulatory enforcement actions; the duration of the Bank’s limitation on the growth of its CRE portfolio, and the potentially adverse impact thereof on the Company’s overall business, financial condition and results of operation; the cost of compliance and significant amount of time required of management to comply with regulatory requirements; results of changes in law, regulations or regulatory practices; the Company’s ability to raise capital; competitive factors, including price competition; 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; the Company’s ability to attract and retain key management and staff; any failure by the Company to maintain effective internal control over financial reporting; larger-than-expected losses from the sale of assets; and the potential that net charge-offs are higher than expected or for 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. For more information, see the risk factors described in the Company’s Annual Report on Form 10-K and other filings with the Securities and Exchange Commission.

(5) The core operating efficiency ratio is not required by U.S. GAAP or by applicable bank regulatory requirements, but is a metric used by management to evaluate core operating efficiency. Since there is no authoritative requirement to calculate this ratio, our ratio is not necessarily comparable to similar efficiency measures disclosed or used by other companies in the financial services industry.

Since there is no authoritative requirement to calculate the TCE ratio, our TCE ratio is not necessarily comparable to similar capital measures disclosed or used by other companies in the financial services industry.
