“In the first quarter of 2019, we achieved double-digit year-over-year earnings growth with net income and earnings per share up 12% over first quarter 2018. In addition, we continued to build our tangible capital which increases our ability to be opportunistic in executing on our long-term growth strategies,” said NBT President and CEO John H.

This customer-focused approach drives our success and is the foundation of our efforts to build shareholder value.”

¹ The change in the Company’s quarterly deposit costs from December 31, 2015 to March 31, 2019 of 0.26% divided by the change in Federal Reserve’s target fed funds rate from December 2015 to March 2019 of 2.25%

Net interest income was $77.7 million for the first quarter of 2019, down $1.2 million, or 1.5%, from the previous quarter. The fully taxable equivalent (“FTE”) net interest margin was 3.64% for the three months ended March 31, 2019, up 3 basis points (“bps”) from the previous quarter, as higher rates on lower average interest-earning assets more than offset higher funding costs on higher average interest-bearing liabilities. Interest income increased $0.8 million, or 0.9%, as the yield on average interest-earning assets increased 14 bps from the prior quarter to 4.28%, while average interest-earning assets of $8.7 billion remained relatively consistent with prior quarter. Interest expense was up $2.0 million, or 17.2%, as the cost of interest-bearing liabilities increased 15 bps to 0.92% for the quarter ended March 31, 2019, driven by interest-bearing deposit costs increasing 16 bps along with increased short-term borrowings cost. The Federal Reserve has raised its target fed funds rate nine times from December 2015 through March 2019 for a total increase of 225 bps. During this same cycle of increasing rates, the Company’s average cost of deposits increased by 26 bps, resulting in a full cycle deposit beta of 11.7%.

Net interest income was $77.7 million for the first quarter of 2019, up $4.2 million, or 5.7%, from the first quarter of 2018. The FTE net interest margin of 3.64% was up 7 bps from the first quarter of 2018. Interest income increased $10.6 million, or 13.1%, as the yield on average interest-earning assets increased 36 bps from the same period in 2018, and average interest-earning assets increased $314.0 million, or 3.7%, primarily due to a $294.2 million increase in average loans. Interest expense increased $6.4 million, as the cost of interest-bearing liabilities increased 41 bps, driven by interest-bearing deposit costs increasing 38 bps combined with a 72 basis point increase in short-term borrowing costs.

Noninterest income for the three months ended March 31, 2019 was $33.8 million, up $7.9 million, or 30.4%, from the prior quarter and up $2.5 million, or 8.1%, from the first quarter of 2018. The increase from the prior quarter was primarily driven by lower net securities losses and seasonal increases in both insurance and other financial services revenue and retirement plan administration fees. In the fourth quarter of 2018, the Company restructured the investment portfolio by selling $109 million of lower-yielding bonds and reinvesting the proceeds in higher-yielding bonds, which resulted in a $6.6 million loss on securities sold. Excluding net securities gains (losses), noninterest income for the three months ended March 31, 2019 would have been $33.8 million, up $0.9 million, or 2.7% from the prior quarter and up $2.6 million, or 8.2% from the first quarter of 2018. The increase from the first quarter of 2018 was primarily due to higher retirement plan administration fees resulting from the acquisition of Retirement Plan Services, LLC (“RPS”) in the second quarter of 2018.

Noninterest expense for the three months ended March 31, 2019 was $68.5 million, down $0.4 million, or 0.6%, from the prior quarter and up $4.2 million, or 6.5%, from the first quarter of 2018. The decrease from the prior quarter was primarily due to a $1.1 million decrease in other noninterest expense due to the timing of expense items combined with $0.4 million in non-recurring items in the fourth quarter of 2018, partially offset by a $0.7 million increase in pension interest and amortization costs. Advertising expense decreased from the prior quarter by $0.5 million due to the timing of expenses in the fourth quarter of 2018. These decreases were partially offset by a $1.0 million increase in occupancy expense due to seasonal expenses. The increase from the first quarter of 2018 was driven by increases in salaries and employee benefits expense, equipment expense and other noninterest expense, which were partially offset by a decrease in loan collection and other real estate owned. Salaries and employee benefits expense increased from the first quarter of 2018 due primarily to the acquisition of RPS in the second quarter of 2018 and related employee benefits expenses combined with a $0.4 million increase in salaries related to the tax reform initiatives implemented in the first quarter of 2018.

Income tax expense for the three months ended March 31, 2019 was $8.1 million, up $7.4 million, from the prior quarter and up $1.1 million from the first quarter of 2018. The effective tax rate of 21.8% for the first quarter of 2019 was up from 2.5% for the fourth quarter of 2018 and up from 21.2% for the first quarter of 2018. The increase in income tax expense from the prior quarter was primarily due to a $5.5 million tax benefit recorded in the fourth quarter of 2018 primarily related to one-time income tax return accounting method changes during the fourth quarter of 2018. The increase in income tax expense from the first quarter of 2018 was primarily due to a higher level of taxable income.

Asset Quality

Net charge-offs of $6.9 million for the three months ended March 31, 2019 were comparable to $6.8 million for the prior quarter and for the first quarter of 2018. Provision expense was lower at $5.8 million for the three months ended March 31, 2019, as compared with $6.5 million for the prior quarter and as compared with $7.5 million for the first quarter of 2018. Annualized net charge-offs to average loans for the first quarter of 2019 was 0.41%, up from 0.39% for the prior quarter and down from 0.42% for the first quarter of 2018.

Nonperforming loans to total loans was 0.42% at March 31, 2019, down 2 bps from 0.44% for the prior quarter and down 1 bp from 0.43% at March 31, 2018. Past due loans as a percentage of total loans were 0.52% at March 31, 2019, down from 0.55% at December 31, 2018 and down from 0.53% at March 31, 2018.

The allowance for loan losses totaled $71.4 million at March 31, 2019, compared to $72.5 million at December 31, 2018 and $70.2 million at March 31, 2018. The allowance for loan losses as a percentage of loans was 1.04% (1.09% excluding acquired loans) at March 31, 2019, compared to 1.05% (1.10% excluding acquired loans) at December 31, 2018 and 1.06% (1.12% excluding acquired loans) at March 31, 2018.

Balance Sheet

Total assets were $9.5 billion at March 31, 2019 compared with $9.6 billion at December 31, 2018. Loans were $6.9 billion at March 31, 2019, comparable to December 31, 2018. In the first quarter of 2019, loan growth in commercial and commercial real estate was offset by run-off in our dealer finance portfolio. This is consistent with the Company’s strategy to focus on our higher returning portfolios thus reducing the need to rely more on price sensitive deposits to fund loan growth during the current interest rate environment. Total deposits were $7.6 billion at March 31, 2019, up $249.4 million, or 3.4%, from December 31, 2018, reflecting growth in core and municipal deposits. Stockholders’ equity was $1.0 billion, representing a total equity-to-total assets ratio of 10.85% at March 31, 2019, compared with $1.0 billion or a total equity-to-total assets ratio of 10.65% at December 31, 2018.

Dividend

On March 25, 2019, the Company announced that the Board of Directors approved a second-quarter 2019 cash dividend of $0.26 per share. The dividend will be paid on June 14, 2019 to shareholders of record as of May 31, 2019.
