NBT BANCORP INC. ANNOUNCES SECOND QUARTER 2026 RESULTS AND APPROVES AN 8.1% CASH DIVIDEND INCREASE

NORWICH, NY (July 27, 2026) – 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, 2026.

Net income for the second quarter of 2026 was $53.0 million, or $1.02 per diluted common share, compared to $22.5 million, or $0.44 per diluted common share, for the

second quarter of 2025, and $51.1 million, or $0.98 per diluted common share, for the first quarter of 2026. Operating diluted earnings per share(1), a non-GAAP measure, was $1.01 for the second quarter of 2026, compared to $0.88 for

the second quarter of 2025 and $0.97 for the first quarter of 2026.

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 comparison to the second quarter of 2025 is

significantly impacted by the Evans acquisition.

CEO Comments

“The second quarter demonstrated the strength and momentum of NBT’s diversified banking franchise,” said NBT President and CEO Scott

Kingsley. “We generated significantly stronger earnings than the prior year quarter, grew loans across every business line and expanded our net interest margin to 3.73%, an increase of 14 basis points from one year ago. These results reflect the

trust our customers place in us, the dedication of our employees and our disciplined approach to building long-term relationships and sustainable growth. With strong balance sheet fundamentals, healthy loan growth and continued momentum across

our franchise, we are well positioned as we enter the second half of 2026.”

“We are also pleased to announce that we have increased our quarterly cash dividend for the fourteenth consecutive year to $0.40 per share in the third quarter,”

added Kingsley. “This increase in the quarterly cash dividend of 8.1% affirms our continued commitment to providing favorable long-term returns to our shareholders.”

CET1 ratio of 12.24%; Leverage ratio of 9.85%

Loans

Period end total loans were $11.87 billion at June 30, 2026, compared to $11.60 billion at December 31, 2025, with all business lines experiencing growth in the second quarter of

2026.

Period end total loans increased $276.0 million, or 2.4% from December 31, 2025 which included a $52.4 million decrease in the other consumer and residential solar portfolios,

which are in a planned run-off status.

Deposits

Total deposits at June 30, 2026 were $13.54 billion compared to $13.50 billion at December 31, 2025. Deposit mix

characteristics improved with an increase in demand deposits, interest-bearing checking, savings and money market accounts, partially offset by a decrease in time deposits.

Total deposits decreased $205.7 million from March 31, 2026, primarily due to expected seasonal municipal outflows.

The loan to deposit ratio was 87.7% at June 30, 2026, compared to 85.9% at December 31, 2025.

Net Interest Income and Net Interest Margin

Net interest income for the second quarter of 2026 was $137.0 million, an increase of $2.6 million, or

1.9%, from the first quarter of 2026 and an increase of $12.7 million, or 10.3%, from the second quarter of 2025. The increase in net interest income from the first quarter of 2026 was driven by one additional day in the second quarter of

2026, organic growth in interest-earning assets and a decrease in funding costs. The increase in net interest income from the second quarter of 2025 resulted primarily from the improvement in net interest margin, the Evans acquisition,

organic growth in interest-earning assets and a decrease in funding costs.

The NIM on an FTE basis for the second quarter of 2026 was 3.73%, an increase of 1 bp from the first quarter of 2026, as a 1 bp decrease in the cost of funds more than offset a 1

bp decline in earning asset yields. The NIM on an FTE basis increased 14 bps from the second quarter of 2025 due to the impact of the Evans acquisition, organic growth and a decrease in the cost of funds.

3

Earning asset yields for the three months ended June 30, 2026 decreased 1 bp from the prior quarter to 5.05%. Loan yields for the three months ended June 30, 2026 decreased 2 bps

from the prior quarter to 5.64%. Earning asset yields decreased 7 bps from the same quarter in the prior year due to Federal Reserve interest rate cuts in 2025. Average earning assets increased $109.8 million, or 0.7%, from the first

quarter of 2026 and grew $846.2 million, or 6.1%, from the second quarter of 2025 due primarily to the addition of the interest-earning assets acquired from Evans and organic earning asset growth.

Total cost of deposits, including noninterest bearing deposits, was 1.33% for the second quarter of 2026, a decrease of 1 bp from the prior quarter, primarily due to the decrease

in the cost of time deposits. Total cost of deposits decreased 18 bps from the same period in the prior year.

Total cost of funds for the three months ended June 30, 2026 was 1.41%, a decrease of 1 bp from the prior quarter and a decrease of 21 bps from the second quarter of 2025.

Asset Quality and Allowance for Loan Losses

Net charge-offs to total average loans for the second quarter of 2026 was 15 bps, compared to 17 bps in the prior quarter primarily due to a decrease in commercial net

charge-offs, partially offset by an increase in residential solar and other consumer net charge-offs.

Nonperforming assets to total assets was 0.40% at June 30, 2026, up from 0.38% at March 31, 2026 and up from 0.33% at December 31, 2025. The increase in nonperforming assets was

primarily due to an additional commercial lending relationship placed in nonaccrual status during the quarter. Past due loans to total loans increased 23 basis points from March 31, 2026, driven primarily by an increase in past due

commercial loans. The majority of these loans are expected to return to current status in the third quarter.

Provision expense for the three months ended June 30, 2026 was $6.1 million, compared to $5.6 million for the first quarter of 2026. The increase in the provision for loan losses

during the quarter was primarily due to providing for the second quarter’s loan growth.

The allowance for loan losses was $140.5 million, or 1.18% of total loans, at June 30, 2026, compared to $138.6 million, or 1.20% of total loans, at March 31, 2026 and compared

to $138.0 million, or 1.19% of total loans, at December 31, 2025. The increase in the allowance for loan losses in the second quarter of 2026 was primarily driven by providing for the

second quarter’s loan growth, partially offset by portfolio mix changes with the run-off of the other consumer and residential solar portfolios.

The reserve for unfunded loan commitments was $5.5 million at June 30, 2026 and March 31, 2026, compared to $5.8 million at December 31, 2025.

Noninterest Income

Total noninterest income, excluding securities gains, was $49.6 million for the three months ended June 30, 2026, consistent with the first quarter of 2026, and up $2.7 million,

or 5.8%, from the second quarter of 2025.

Service charges on deposit accounts were comparable to the prior quarter and higher than the second quarter of 2025 due primarily to the Evans acquisition and new account growth.

Card services income increased $0.6 million, or 9.7%, from the prior quarter and increased $0.5 million, or 8.8% from the second quarter of 2025. The increase was driven by

seasonal increased volumes.

Retirement plan administration fees increased $0.4 million, or 2.2%, from the prior quarter and increased $1.2 million, or 7.8%, from the second quarter of 2025. The increase

from the prior quarter and the second quarter of 2025 was driven by higher activity-based fees, additional fees from new customer relationships and increased market values of assets under administration.

4

Noninterest Expense

Total noninterest expense was $111.4 million for the second quarter of 2026, compared to $112.2 million for the first quarter of 2026 and $122.6 million for the second quarter of

2025. Excluding acquisition expenses of $17.2 million in the second quarter of 2025, noninterest expense was 5.7% higher than the second quarter of 2025 primarily due to the Evans acquisition and continued investments in our people,

markets and infrastructure.

Salaries and benefits increased 0.4% from the prior quarter driven by a full quarter of merit pay increases, which were effective in March, one additional payroll day and higher

medical expenses. The increase was 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 2025 was driven by the impact of the Evans acquisition as NBT added 200 Evans employees in May 2025, annual merit pay increases and higher medical expenses.

Technology and data services were consistent with the prior quarter and increased $1.0 million from the second quarter of 2025 primarily due to the Evans acquisition, timing of

planned activities and ongoing investment in enterprise technology initiatives.

Occupancy costs decreased $1.5 million from the prior quarter and increased $0.4 million from the second quarter of 2025. The $1.5 million decrease from the prior quarter was

driven by lower seasonal maintenance and utilities costs following the harsh winter conditions across the footprint in the first quarter of 2026. The $0.4 million increase from the second quarter of 2025 was driven

by additional expenses from the Evans acquisition and higher facilities costs related to new branch banking locations.

Professional fees and outside services were consistent with the prior quarter and increased $0.6 million from the second quarter of 2025 primarily due to the Evans acquisition

and the timing of various initiatives.

No provision expense for unfunded loan commitments was recognized for the three months ended June 30, 2026, compared to expense of $1.7 million for the three months ended June

30, 2025, which  included $0.5 million of acquisition-related provision associated with unfunded loan commitments acquired in the Evans acquisition.

Other expenses were consistent with the prior quarter and increased $0.6 million from the second quarter of 2025. The increase from the second quarter of 2025 reflects the Evans

acquisition including increased FDIC insurance expense, travel and charitable contributions.

Income Taxes

The effective tax rate for the second quarter of 2026 was 23.3%, which was consistent with the prior quarter and down from 26.7% for the second quarter of 2025. The decrease in

the effective tax rate from the second quarter of 2025 was primarily due to the second quarter 2025 estimated impact of nondeductible acquisition expenses related to the Evans acquisition and a lower level of tax-exempt income as a

percentage of total pretax income.

Capital

Tangible common equity to tangible assets(1) was 9.16% at June 30, 2026. Tangible book value per share(2) was $27.71 at June 30, 2026, which increased 4.4%

from $26.54 at December 31, 2025 and increased 12.8% from $24.57 at June 30, 2025.

Stockholders’ equity increased $47.7 million from December 31, 2025 driven by net income generation of $104.2 million, partially offset by dividends declared of $38.5 million,

the repurchase of common stock of $14.0 million and a $6.5 million increase in accumulated other comprehensive loss reflecting the change in the fair value of securities available for sale.

As of June 30, 2026, CET1 capital ratio of 12.24%, leverage ratio of 9.85% and total risk-based capital ratio of 14.18%.

5

Dividend

The Board of Directors approved a third-quarter cash dividend of $0.40 per share at a meeting held earlier today. The dividend represents a $0.03 per share, or 8.1%, increase

over the dividend paid in the third quarter of 2025. This is the Company’s fourteenth consecutive year of annual dividend increases. The dividend will be paid on September 15, 2026 to stockholders of record as of September 1, 2026.

Stock Repurchase

The Company purchased 68,595 shares of its common stock during the second quarter of 2026 for a total of $3.0 million at an average price of $43.96 per share under its previously

announced stock repurchase program. 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, 2026, there were 1,431,405 shares available for repurchase under this plan.

Subordinated Debt Redemption

On June 30, 2026, the Company redeemed $25 million of subordinated debt using existing liquidity sources. The subordinated debt had a fixed rate of 3.50% which converted to a

floating rate at 6.50% in the second quarter of 2026.
