NBT BANCORP INC. ANNOUNCES SECOND QUARTER 2025 NET INCOME AND APPROVES AN 8.8% CASH DIVIDEND INCREASE

NORWICH, NY (July 28, 2025) – NBT Bancorp Inc. (“NBT” or the “Company”) (NASDAQ: NBTB) reported net income and diluted earnings per share for the three and six months ended June 30, 2025.

Net income for the second quarter of 2025 was $22.5 million, or $0.44 per diluted common share, compared to $32.7 million, or $0.69 per diluted common share, for the second quarter of 2024, and $36.7 million, or $0.77 per diluted common share, for the first quarter of 2025. Operating diluted earnings per share⁽¹⁾, a non-GAAP measure, was $0.88 for the second quarter of 2025, compared to $0.69 for the second quarter of 2024 and $0.80 for the first quarter of 2025.

The Company completed the acquisition of Evans Bancorp, Inc. (“Evans”) on May 2, 2025, adding 200 employees and 18 banking locations in Western New York, $1.67 billion in loans and $1.86 billion in deposits. In connection with the transaction, the Company issued 5.1 million shares of common stock, with a value of $221.8 million as of the closing date. The comparisons to the first quarter of 2025 and to the second quarter of 2024 are significantly impacted by the Evans acquisition.

CEO Comments

“Continued improvement in net interest margin results and the additive impact of our successful merger with Evans Bancorp, Inc. resulted in second quarter operating earnings per share that were 28% above the second quarter of 2024 and 10% higher than the first quarter of this year,” said NBT President and CEO Scott Kingsley. “The detailed plans executed by our integration team resulted in a seamless transition experience, and we are excited that we are now building on the relationships Evans established with customers, employees, communities and shareholders in the Western Region of New York.”

“We are also pleased to announce that we have increased our dividend for the thirteenth consecutive year to $0.37 per share in the third quarter,” added Kingsley. “This increase in the quarterly cash dividend of 8.8% affirms our continued commitment to providing favorable long-term returns to our shareholders.”

Loans

■

Period end total loans were $11.62 billion at June 30, 2025, compared to $9.97 billion at December 31, 2024 and $9.85 billion at June 30, 2024.

■

Period end total loans increased $1.65 billion from December 31, 2024 and $1.77 billion from June 30, 2024. Excluding the other consumer and residential solar portfolios, which are in a planned run-off status, and the loans acquired from Evans, period end loans increased $221.0 million, or 2.5%, from June 30, 2024.

Deposits

■

Total deposits at June 30, 2025 were $13.52 billion, compared to $11.55 billion at December 31, 2024 and $11.27 billion at June 30, 2024. Excluding the deposits acquired from Evans, deposits increased $104.4 million from December 31, 2024 and $379.7 million, or 3.4%, from June 30, 2024. Deposit mix characteristics also improved with an increase in demand deposits, interest-bearing checking and money market accounts offset by a decrease in time deposits.

■

The loan to deposit ratio was 86.0% at June 30, 2025, compared to 86.3% at December 31, 2024 and 87.4% at June 30, 2024.

Net Interest Income and Net Interest Margin

■

Net interest income for the second quarter of 2025 was $124.2 million, an increase of $17.0 million, or 15.9%, from the first quarter of 2025 and an increase of $27.0 million, or 27.8%, from the second quarter of 2024. The increase in net interest income from the first quarter of 2025 was largely attributed to the Evans acquisition with higher earning asset yields also contributing to the increase. The increase in net interest income from the second quarter of 2024 resulted primarily from the Evans acquisition, the improvement in net interest margin and organic growth in interest-earning assets.

■

The NIM on an FTE basis for the second quarter of 2025 was 3.59%, an increase of 15 bps from the first quarter of 2025. This increase was primarily driven by an increase in earning asset yields and acquisition-related net accretion. The NIM on an FTE basis increased 41 bps from the second quarter of 2024 due to higher yields on earning assets, including acquisition-related net accretion and a decrease in the cost of interest-bearing liabilities.

■

Earning asset yields for the three months ended June 30, 2025 increased 17 bps from the prior quarter to 5.12%. Loan yields for the three months ended June 30, 2025 increased 15 bps from the prior quarter to 5.77%, due to loans originating at higher rates than portfolio yields during the quarter and acquisition-related net accretion. Earnings asset yields increased 20 bps from the same quarter in the prior year as new loan yields were priced higher than portfolio yields and acquisition-related net accretion. Average earning assets increased $1.26 billion, or 9.9%, from the first quarter of 2025 and grew $1.59 billion, or 12.9%, from the second quarter of 2024 due primarily to the addition of $1.95 billion in interest-earnings assets in May of 2025 from the Evans acquisition and organic earning asset growth.

■

NBT completed the sale of the Evans available for sale investment securities portfolio in May which contributed to the increase in short-term interest-bearing accounts in the second quarter of 2025. At acquisition, the portfolio had a fair value of approximately $255 million.

■

Total cost of deposits, including noninterest bearing deposits, was 1.51% for the second quarter of 2025, an increase of 2 bps from the prior quarter as Evans higher cost of deposits, primarily in interest-bearing checking and savings deposit accounts, were partially offset by a decrease in the cost of time deposits. Total cost of deposits decreased 17 bps from the same period in the prior year.

■

Total cost of funds for the three months ended June 30, 2025 was 1.62%, an increase of 2 bps from the prior quarter and a decrease of 23 bps from the second quarter of 2024.

Asset Quality and Allowance for Loan Losses

■

Net charge-offs to total average loans for the second quarter of 2025 was 9 bps compared to 27 bps in the prior quarter primarily due to a decrease in both commercial and consumer net charge-offs. Included in net charge-offs for the first quarter of 2025 was a $2.1 million write-down of a nonperforming commercial real estate loan to the estimated fair value in the first quarter of 2025.

■

Nonperforming assets to total assets was 0.29% at June 30, 2025, compared to 0.35% at March 31, 2025 and compared to 0.38% at December 31, 2024. During the second quarter of 2025, the foreclosure on the collateral of a nonperforming commercial real estate loan, where the Company was not the lead bank, was completed. The Company’s participation interest was transferred into a newly formed special purpose entity structured as a limited liability company, which will be accounted for using the equity method of accounting and was reported in other assets.

■

Provision expense for the three months ended June 30, 2025 was $17.8 million, compared to $7.6 million for the first quarter of 2025. The increase in the provision for loan losses during the quarter was due to $13.0 million of acquisition-related provision for loan losses and modest deterioration in the economic forecast, partially offset by a decrease in net charge-offs from the prior quarter and portfolio mix changes with the run-off of the other consumer and residential solar portfolios.

■

The allowance for loan losses was $140.2 million, or 1.21% of total loans, at June 30, 2025, compared to $117.0 million, or 1.17% of total loans, at March 31, 2025 and compared to $116.0 million, or 1.16% of total loans, at December 31, 2024. The increase in the allowance for loan losses in the second quarter of 2025 included $20.7 million of allowance for acquired Evans loans, which included both the $13.0 million of non-purchased credit deteriorated allowance recognized through the provision for loan losses and the $7.7 million of purchased credit deteriorated allowance reclassified from loans. In addition, a modest deterioration of the economic forecast contributed to the increase in the allowance for loan losses, partially offset by the portfolio mix changes with the run-off of the other consumer and residential solar portfolios.

■

The reserve for unfunded loan commitments was $6.2 million at June 30, 2025, compared to $4.5 million at March 31, 2025 and compared to $4.4 million at December 31, 2024. The provision for unfunded loan commitments in the second quarter of 2025 included $0.5 million of acquisition-related provision for unfunded loan commitments.

Noninterest Income

■

Total noninterest income, excluding securities gains (losses), was $46.8 million for the three months ended June 30, 2025, down $0.7 million, or 1.5%, from the first quarter of 2025, and up $3.5 million, or 8.1%, from the second quarter of 2024.

■

Card services income increased $0.8 million from the prior quarter and increased $0.5 million from the second quarter of 2024, driven by the Evans acquisition and increased volumes.

■

Retirement plan administration fees were consistent with the prior quarter and increased $0.9 million, or 6.2%, from the second quarter of 2024. The increase from the second quarter of 2024 was driven by higher market values of assets under administration and the acquisition of a small third-party administrator (“TPA”) business in the fourth quarter of 2024.

■

Wealth management fees were consistent with the prior quarter and increased $0.5 million, or 5.0%, from the second quarter of 2024. The increase from the second quarter of 2024 was driven by market performance and growth in new customer accounts.

■

Insurance revenues decreased $0.7 million from the seasonally high first quarter of 2025 and increased 6.5% from the prior year due to organic growth.

■

Bank owned life insurance income decreased from the first quarter of 2025 due to a $1.3 million gain recognized in the first quarter of 2025.

Noninterest Expense

■

Total noninterest expense was $122.6 million for the second quarter of 2025, compared to $99.9 million for the first quarter of 2025 and $89.6 million for the second quarter of 2024. Total noninterest expense, excluding $17.2 million of acquisition expenses in the second quarter of 2025 and $1.2 million of acquisition expenses in the first quarter of 2025, increased 6.8% compared to the previous quarter and increased 17.7% from the second quarter of 2024. The increase was primarily due to the acquisition of Evans.

■

Salaries and benefits increased 5.7% from the prior quarter driven by the Evans acquisition as we added 200 Evans employees to NBT in May, a full quarter of merit pay increases, which were effective in March, and higher medical costs. These increases were partially offset by lower payroll taxes and stock-based compensation expenses which are seasonally higher in the first quarter. The increase from the second quarter of 2024 was driven by the impact of the Evans acquisition, merit pay increases, higher medical and other benefit costs.

■

Technology and data services increased $0.6 million from the prior quarter and $1.6 million from the second quarter of 2024 primarily due to the Evans acquisition, timing of planned initiatives and continued investment in digital platform solutions.

■

Occupancy costs were consistent from the prior quarter due to lower seasonal maintenance and utilities costs being offset by the additional expenses from the Evans acquisition. The $1.4 million increase from the second quarter of 2024 was driven by the additional expenses from the Evans acquisition, higher utilities and higher facilities costs related to new banking locations.

■

Amortization of intangible assets increased $0.9 million from the prior quarter and from the second quarter of 2024 primarily due to the amortization of intangible assets related to the Evans acquisition.

Income Taxes

■

The effective tax rate for the second quarter of 2025 was 26.7%, which was up from 22.0% for the second quarter of 2024 primarily due to the estimated impact of acquisition expenses related to the Evans acquisition and a lower level of tax-exempt income as a percentage of total taxable income.

Capital

■

Tangible common equity to tangible assets⁽¹⁾ was 8.30% at June 30, 2025. Tangible book value per share⁽²⁾ was $24.57 at June 30, 2025, $24.74 at March 31, 2025 and $22.54 at June 30, 2024.

■

Stockholders’ equity increased $279.0 million from December 31, 2024 driven by the Evans acquisition adding $221.8 million of capital, net income generation of $59.3 million and a $31.4 million decrease in accumulated other comprehensive loss reflecting the change in the fair value of securities available for sale, partially offset by dividends declared of $33.9 million.

■

As of June 30, 2025, CET1 capital ratio of 11.37%, leverage ratio of 9.55% and total risk-based capital ratio of 14.48%.

Dividend

■

The Board of Directors approved a third-quarter cash dividend of $0.37 per share at a meeting held earlier today. The dividend represents a $0.03 per quarter, or 8.8%, increase over the dividend paid in the third quarter of 2024. This is the Company’s thirteenth consecutive year of annual dividend increases. The dividend will be paid on September 15, 2025 to stockholders of record as of September 1, 2025.

Stock Repurchase

■

The Company did not purchase shares of its common stock during the three months ended June 30, 2025. The Company may repurchase shares of its common stock from time to time to mitigate the potential dilutive effects of stock-based incentive plans and other potential uses of common stock for corporate purposes. As of June 30, 2025, there were 1,992,400 shares available under the Company’s share repurchase program.

Evans Bancorp, Inc. Merger

■

On May 2, 2025, the Company completed the acquisition of Evans. Evans was headquartered in Williamsville, New York. Its primary subsidiary, Evans Bank, National Association, was a federally-chartered national banking association operating 18 banking locations in Western New York.

■

In connection with the acquisition, the Company issued 5.1 million shares and acquired approximately $130.4 million of net assets, including $1.67 billion of loans and $1.86 billion in deposits. As a result of the acquisition, the Company recorded $91.4 million in goodwill and a $33.2 million core deposit intangible. As of the acquisition date, the fair value discount was $95.2 million for loans, net of the reclassification of the purchase credit deteriorated allowance and a $0.6 million net discount related to long-term debt.

Subordinated Debt Redemption

■

In July of 2025, the Company redeemed $118 million of subordinated debt that had a weighted average rate of 5.45% using existing liquidity sources. The $118 million of subordinated debt would have converted to a weighted average floating rate above 9%.
