Participants should refer to the Plan Agreement or Summary Plan Description for a more complete description of the Plan&#x2019;s provisions.&lt;/span&gt; &lt;/div&gt;

  &lt;/div&gt;
  &lt;div style="text-align: justify; font-size: 10pt;"&gt;&#160;
  &lt;/div&gt;
  &lt;div style="text-align: justify;"&gt;
   &lt;span style="font-size: 10.0pt;"&gt;The Plan is a defined contribution plan as defined under Section 401(a) of the Internal Revenue Code (&#x201c;IRC&#x201d;), sponsored by NBT Bancorp Inc. (&#x201c;the Sponsor&#x201d;, &#x201c;the Plan Administrator&#x201d; or &#x201c;the Company&#x201d;). The Sponsor is responsible for administration of the Plan. NBT Bank, N.A, is a wholly-owned subsidiary of NBT Bancorp Inc. NBT Bank, N.A. is the trustee of the Plan (&#x201c;the Trustee&#x201d;) and Charles Schwab Bank is the Custodian of the Plan. EPIC Retirement Plan Services, a wholly&#x2011;owned subsidiary of NBT Financial Services, Inc., a wholly&#x2011;owned subsidiary of the Sponsor, is the Plan&#x2019;s record keeper. The assets of the Plan are held, administered and managed in accordance with the terms and conditions of the Trust Agreement, which is considered to be an integral part of the Plan.&lt;/span&gt;
  &lt;/div&gt;
  &lt;div style="text-align: justify; font-size: 10pt;"&gt;&#160;
  &lt;/div&gt;
  &lt;div style="text-align: justify;"&gt;
   &lt;span style="font-size: 10.0pt;"&gt;The Plan is subject to the provisions of the Employee Retirement Income Security Act of 1974, as amended (&#x201c;ERISA&#x201d;).&lt;/span&gt;
  &lt;/div&gt;
  &lt;div style="text-align: justify; font-size: 10pt;"&gt;&#160;
  &lt;/div&gt;
  &lt;div style="text-align: justify;"&gt;
   &lt;span style="font-size: 10.0pt;"&gt;The Plan was amended to include employees of Karl W. Reynard Agency effective July 1, 2024 and employees of Paco, Inc. effective November 1, 2024.&lt;/span&gt;
  &lt;/div&gt;
  &lt;div style="text-align: justify; font-size: 10pt;"&gt;&#160;
  &lt;/div&gt;
  &lt;div style="text-align: justify;"&gt;
   &lt;span style="font-size: 10.0pt;"&gt;The Plan was amended to include employees of Evans Bancorp, Inc. effective May 2, 2025.&lt;/span&gt;
  &lt;/div&gt;
  &lt;div style="text-align: justify; font-size: 10pt;"&gt;&#160;
  &lt;/div&gt;
  &lt;div style="text-align: justify;"&gt;
   &lt;span style="font-size: 10.0pt;"&gt;Effective January 1, 2025, the Plan was amended to update provisions related to employees acquired in IRC &#xa7;410(b)(6)(C) transactions (including eligibility as of the transaction date and crediting of predecessor employer service for eligibility and vesting purposes). The Plan was also amended to permit in&#x2011;plan Roth conversions effective January 1, 2026.&lt;/span&gt;
  &lt;/div&gt;
  &lt;div style="text-align: justify; font-size: 10pt;"&gt;&#160;
  &lt;/div&gt;
  &lt;div style="text-align: justify;"&gt;
   &lt;span style="font-size: 10.0pt;"&gt;Employees acquired in certain IRC &#xa7;410(b)(6)(C) transactions may become eligible as of the transaction date, as provided under the Plan.&lt;/span&gt;
  &lt;/div&gt;
  &lt;div style="text-align: justify; font-size: 10pt;"&gt;&#160;
  &lt;/div&gt;
  &lt;div style="text-align: justify;"&gt;
   &lt;span style="font-size: 10.0pt; font-weight: bold;"&gt;Eligibility&lt;/span&gt;
  &lt;/div&gt;
  &lt;div style="text-align: justify; font-size: 10pt;"&gt;&#160;
  &lt;/div&gt;
  &lt;div style="text-align: justify;"&gt; &lt;span style="font-size: 10.0pt;"&gt;All employees who are age 21 or over and scheduled to complete 1,000 hours of service or have completed 1,000 hours of service are eligible to participate in the Plan. Eligible employees are required to complete 30 days of employment prior to entry into the Plan. A deemed election becomes effective as of the first day of the month the eligible employee becomes a participant and is eligible to make a deferral election to the Plan.&lt;/span&gt; &lt;/div&gt;
  &lt;div style="text-align: justify; font-size: 10pt;"&gt;&#160;
  &lt;/div&gt;
  &lt;div style="text-align: justify;"&gt;
   &lt;span style="font-size: 10.0pt; font-weight: bold;"&gt;Contributions and Deferrals&lt;/span&gt;
  &lt;/div&gt;
  &lt;div style="text-align: justify; font-size: 10pt;"&gt;&#160;
  &lt;/div&gt;
  &lt;div style="text-align: justify;"&gt;
   &lt;span style="font-size: 10.0pt;"&gt;Participants may make pre&#x2011;tax and post-tax contributions in whole percentages or may elect a flat dollar contribution up to Internal Revenue Service (&#x201c;IRS&#x201d;) limitations for any plan year. The post-tax contributions are deferrals to Roth accounts.&lt;/span&gt;
  &lt;/div&gt;
  &lt;div style="text-align: justify; font-size: 10pt;"&gt;&#160;
  &lt;/div&gt;
  &lt;div style="text-align: justify;"&gt; &lt;span style="font-size: 10.0pt;"&gt;The Plan includes provisions for automatic elective contributions under which any employee that meets certain eligibility requirements will be automatically enrolled in the Plan and will automatically have 6% withheld from his or her compensation and contributed to the Plan. The employee will have to elect to opt out of the qualified automatic contribution election.&lt;/span&gt; &lt;/div&gt;
  &lt;div style="text-align: justify; font-size: 10pt;"&gt;&#160;
  &lt;/div&gt;
  &lt;div style="text-align: justify;"&gt; &lt;span style="font-size: 10.0pt;"&gt;The Company&#x2019;s matching contribution is 100% of each participant&#x2019;s contribution up to 1% of compensation plus 50% of the next 5% of compensation for a total matching contribution of up to 3.5% of compensation. The Company match amounted to $5,916,604 and $5,100,193 in 2025 and 2024, respectively. A discretionary amount, determined by the Sponsor&#x2019;s Board of Directors, may be contributed to the Plan each year. To share in this discretionary contribution, participants must be actively employed on the last day of the year, have completed 1,000 hours of service and have contributed a minimum percentage of compensation during the year as determined annually by the Company. The amount is allocated to participants on a pro-rata basis, based on compensation. No discretionary contributions were made for 2025. During 2024, discretionary contributions of $1,422,473 were approved by the Sponsor&#x2019;s board of directors and were paid during 2025. This discretionary contribution is included in contributions receivable from employer in the Statement of Net Assets Available for Plan Benefits as of December 31, 2024.&lt;/span&gt;&lt;/div&gt;&lt;div style="text-align: justify;"&gt; &lt;span style="font-size: 10.0pt;"&gt;In addition, as defined in the Plan document, employees participating in the Plan under the Worker Retirement Accumulation Plan (&#x201c;WRAP&#x201d;) design can receive an additional discretionary Company contribution equal to the interest credit on service credits earned under the WRAP design. The Company contribution for employees participating in the WRAP amounted to $675,053 in 2025, which was paid during 2026, and $565,500 in 2024, which was paid during 2025. These discretionary contributions are included in contributions receivable from employer in the Statement of Net Assets Available for Plan Benefits as of December 31, 2025 and 2024.&lt;/span&gt; &lt;/div&gt;

  &lt;/div&gt;
  &lt;div style="text-align: justify;"&gt;
   &lt;span style="font-size: 10.0pt;"&gt;Participants elect to have their contributions invested among the various funds available to the Plan, including NBT Bancorp Inc. common stock. Each participant&#x2019;s account is credited with the Sponsor&#x2019;s and participant&#x2019;s contributions, plan earnings and income, expenses, gains and losses attributable thereto.&lt;/span&gt;
  &lt;/div&gt;
  &lt;div style="text-align: justify; font-size: 10pt; font-weight: bold; font-style: italic;"&gt;&#160;

  &lt;/div&gt;
  &lt;div style="text-align: justify;"&gt; &lt;span style="font-size: 10.0pt;"&gt;Participants&#x2019; contributions and net investment income or loss thereon are 100% vested. The participants&#x2019; vesting in Safe Harbor employer matching contributions are 100% vested upon completion of two years of service. Employer discretionary contributions are vested after five years of service. Participants are considered 100% vested upon termination due to death, retirement or permanent disability.&lt;/span&gt; &lt;/div&gt;
  &lt;div style="text-align: justify; font-size: 10pt; font-weight: bold; font-style: italic;"&gt;&#160;

  &lt;/div&gt;
  &lt;div style="text-align: justify;"&gt;
   &lt;span style="font-size: 10.0pt;"&gt;Participants may make rollover contributions to the Plan through a distribution from a former employer&#x2019;s qualified retirement plan in accordance with the IRC.&lt;/span&gt;
  &lt;/div&gt;
  &lt;div style="text-align: justify; font-size: 10pt; font-weight: bold; font-style: italic;"&gt;&#160;

  &lt;/div&gt;
  &lt;div style="text-align: justify;"&gt; &lt;span style="font-size: 10.0pt;"&gt;Participants may borrow from their account in amounts ranging from $1,000 to the lesser of $50,000 or 50% of the vested 401(k) account balance excluding Company contributions invested in NBT Bancorp Inc. common stock and employer contributions made subsequent to January 1, 1997. Loans, other than loans for the purchase of a primary residence, must be repaid over a period no longer than five years. Loans for the purchase of a primary residence must be repaid over a period no longer than 15 years. Interest is charged at the prime rate plus 1% as of the loan origination date. Participant loans are treated as a transfer from the participant directed accounts into the loan fund. Principal and interest payments on the loans are allocated to the loan fund and transferred into the participant directed accounts based on the participants&#x2019; current investment allocation elections.&lt;/span&gt; &lt;/div&gt;
  &lt;div style="text-align: justify; font-size: 10pt;"&gt;&#160;

  &lt;/div&gt;
  &lt;div style="text-align: justify; font-size: 10pt; font-weight: bold; font-style: italic;"&gt;&#160;
  &lt;/div&gt;
  &lt;div style="text-align: justify; font-weight: bold; font-style: italic;"&gt; &lt;span style="font-size: 10.0pt; font-weight: normal; font-style: normal;"&gt;Upon normal or early retirement, disability, death or termination of employment, the value of a participant&#x2019;s account is paid as requested by the participant. If the value of the vested balance does not exceed $7,000, then the balance will be distributed regardless if the participant requests to receive it. Early retirement is allowed upon reaching age 55 and completion of at least 5 years of service.&lt;/span&gt; &lt;/div&gt;
  &lt;div style="text-align: justify; font-size: 10pt;"&gt;&#160;

  &lt;/div&gt;
  &lt;div style="text-align: justify;"&gt;
   &lt;span style="font-size: 10.0pt;"&gt;Subject to certain limitations prescribed by the Plan and the IRC, terminated participants may elect retirement or other termination withdrawals in either lump sum or partial payments.&lt;/span&gt;
  &lt;/div&gt;

  &lt;div style="text-align: justify;"&gt; &lt;span style="font-size: 10.0pt;"&gt;Forfeitures are applied to reduce the amount of future employer contributions otherwise required to be paid. In 2025 and 2024, forfeitures from non-vested accounts totaled $149,133 and $145,368, respectively, and forfeitures used to reduce employer contributions were $127,451 and $141,313, respectively. Forfeiture account balances totaled $66,394 and $44,712 at December 31, 2025 and 2024, respectively.&lt;/span&gt;&lt;/div&gt;&lt;div style="text-align: justify; font-weight: bold; font-style: italic;"&gt;

  &lt;div style="text-align: justify;"&gt;
   &lt;span style="font-size: 10.0pt;"&gt;Although it has not expressed any intention to do so, the Sponsor has the right to discontinue contributions or terminate the Plan at any time subject to Plan provisions and subject to the provisions of ERISA. In the event of termination of the Plan, each participant&#x2019;s account would become fully vested and the net assets of the Plan would be allocated as prescribed by ERISA and its related regulations.&lt;/span&gt;
  &lt;/div&gt;

  &lt;/div&gt;
  &lt;div style="text-align: justify;"&gt;
   &lt;span style="font-size: 10.0pt;"&gt;Expenses of operating and administering the Plan are generally paid by the Sponsor. The payment of these expenses is not mandated by the Plan and is done so at the discretion of the Sponsor. Loan fees are paid by the borrower.&lt;/span&gt;

   &lt;span style="font-size: 10.0pt;"&gt;The accompanying financial statements have been prepared on the accrual basis of accounting in accordance with accounting principles generally accepted in the United States of America (&#x201c;GAAP&#x201d;). Amounts in prior year&#x2019;s financial statements are reclassified, when necessary, to conform with current year&#x2019;s presentation.&lt;/span&gt;

  &lt;div style="text-align: justify; font-size: 10pt;"&gt;&#160;
  &lt;/div&gt;
  &lt;div style="text-align: justify;"&gt;
   &lt;span style="font-size: 10.0pt;"&gt;The Plan&#x2019;s investments are stated at fair value. The fair value of mutual funds and the common stock of the Sponsor are based on published market quotations. The fair value of the stable value fund is based on the calculated daily net asset values of the fund.&lt;/span&gt;
  &lt;/div&gt;
  &lt;div style="text-align: justify; font-size: 10pt;"&gt;&#160;
  &lt;/div&gt;
  &lt;div style="text-align: justify;"&gt;
   &lt;span style="font-size: 10.0pt;"&gt;Fair value is the price the Plan would receive to sell an asset or pay to transfer a liability in an orderly transaction with a market participant at the measurement date. In the absence of active markets for the identical assets and liabilities, such measurements involve developing assumptions based on market observable data and, in the absence of such data, internal information that is consistent with what market participants would use in a hypothetical transaction that occurs at the measurement date.&lt;/span&gt;
  &lt;/div&gt;
  &lt;div style="text-align: justify; font-size: 10pt;"&gt;&#160;
  &lt;/div&gt;
  &lt;div style="text-align: justify;"&gt;
   &lt;span style="font-size: 10.0pt;"&gt;Observable inputs reflect market data obtained from independent sources, while unobservable inputs reflect our market assumptions. Preference is given to observable inputs. These two types of inputs create the following fair value hierarchy and a financial instrument&#x2019;s categorization within the valuation hierarchy is based upon the lowest level of input that is significant to the fair value measurement. The three levels are defined as follows:&lt;/span&gt;
  &lt;/div&gt;
  &lt;div style="text-align: justify; font-size: 10pt;"&gt;&#160;
  &lt;/div&gt;
  &lt;div style="text-align: justify;"&gt;
   &lt;span style="font-size: 10.0pt;"&gt;Level 1 - Unadjusted quoted prices in active markets that are accessible at the measurement date for identical, unrestricted assets or liabilities;&lt;/span&gt;
  &lt;/div&gt;
  &lt;div style="text-align: justify; font-size: 10pt;"&gt;&#160;
  &lt;/div&gt;
  &lt;div style="text-align: justify;"&gt;
   &lt;span style="font-size: 10.0pt;"&gt;Level 2 - Quoted prices for similar assets or liabilities in active markets, quoted prices in markets that are not active, or inputs that are observable, either directly or indirectly, for substantially the full term of the asset or liability; and&lt;/span&gt;
  &lt;/div&gt;
  &lt;div style="text-align: justify; font-size: 10pt;"&gt;&#160;
  &lt;/div&gt;
  &lt;div style="text-align: justify;"&gt;
   &lt;span style="font-size: 10.0pt;"&gt;Level 3 - Prices or valuation techniques that require inputs that are both significant to the fair value measurement and unobservable (e.g., supported by little or no market activity).&lt;/span&gt;&lt;/div&gt;&lt;div style="text-align: justify; font-size: 10pt;"&gt;
   Investment transactions are recorded on a trade date basis. If a trade is open at the end of the year, a receivable for securities sold but not yet settled or a payable for securities purchased but not yet settled is reflected in the Statement of Net Assets Available for Benefits. Dividends are recorded on the ex-dividend date. Interest income is earned from settlement date and recognized on the accrual basis. The net appreciation in the fair value of investments consists of the realized gains or losses on the sales of investments and the net unrealized appreciation of investments. The methods described above may produce a fair value calculation that may not be indicative of net realizable value or reflective of future fair values. Furthermore, although the Plan believes its valuation methods are appropriate and consistent with other market participants, the use of different methodologies or assumptions to determine the fair value of certain financial instruments could result in a different fair value measurement at the reporting date.
  &lt;/div&gt;
  &lt;div style="text-align: justify; margin-left: 54.7pt; font-size: 10pt;"&gt;&#160;
  &lt;/div&gt;
  &lt;div style="font-weight: bold; font-size: 10pt;"&gt; Benefits Paid to Participants &lt;/div&gt;

  &lt;/div&gt;
  &lt;div style="font-size: 10pt;"&gt;
   Benefit payments to participants are recorded when paid.
  &lt;/div&gt;
  &lt;div style="text-align: justify; margin-left: 54.7pt; font-size: 10pt;"&gt;&#160;

  &lt;/div&gt;
  &lt;div style="text-align: justify; font-weight: bold; font-size: 10pt;"&gt;
   &lt;span style="font-weight: normal;"&gt;Notes receivable from participants are carried at the unpaid principal balance plus interest.&lt;/span&gt;
  &lt;/div&gt;

  &lt;div style="text-align: justify; font-weight: bold; font-size: 10pt;"&gt;&#160;
  &lt;/div&gt;
  &lt;div style="text-align: justify; font-weight: bold; font-size: 10pt;"&gt;
   &lt;span style="font-weight: normal;"&gt;Participant withdrawals are recorded when paid.&lt;/span&gt;

  &lt;div style="text-align: justify; font-size: 10pt;"&gt;&#160;
  &lt;/div&gt;
  &lt;div style="text-align: justify; font-size: 10pt;"&gt;
   The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of net assets available for plan benefits, disclosure of contingent assets and liabilities, and the reported amount of increases and decreases in net assets available for plan benefits. Actual results could differ from those estimates.
  &lt;/div&gt;
  &lt;div style="text-align: justify; font-size: 10pt;"&gt;&#160;
  &lt;/div&gt;
  &lt;div style="text-align: justify; font-size: 10pt;"&gt; &lt;span style="font-weight: bold;"&gt;Risks and Uncertainties&lt;/span&gt; &lt;/div&gt;
  &lt;div style="text-align: justify; font-size: 10pt;"&gt;&#160;
  &lt;/div&gt;
  &lt;div style="text-align: justify; font-size: 10pt;"&gt;
   The Plan invests in various types of investment securities. Investment securities are exposed to various risks, such as interest rate, market and credit risks. Due to the level of risk associated with certain investment securities, it is at least reasonably possible that changes in the values of investment securities will occur in the near term and that such changes could materially affect participant account balances and the amounts reported in the Statements of Net Assets Available for Plan Benefits.

Furthermore, although the Plan believes its valuation methods are appropriate and consistent with other market participants, the use of different methodologies or assumptions to determine the fair value of certain financial instruments could result in a different fair value measurement at the reporting date.

   The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of net assets available for plan benefits, disclosure of contingent assets and liabilities, and the reported amount of increases and decreases in net assets available for plan benefits. Actual results could differ from those estimates.

   The Plan invests in various types of investment securities. Investment securities are exposed to various risks, such as interest rate, market and credit risks. Due to the level of risk associated with certain investment securities, it is at least reasonably possible that changes in the values of investment securities will occur in the near term and that such changes could materially affect participant account balances and the amounts reported in the Statements of Net Assets Available for Plan Benefits.

   &lt;span style="font-size: 10.0pt;"&gt;The stable value fund consists of the Federated Capital Preservation Fund (&#x201c;the Fund&#x201d;), which primarily holds guaranteed investment contracts (&#x201c;GICs&#x201d;) and synthetic guaranteed investment contracts (&#x201c;synthetic GICs&#x201d;). GICs represent deposits which guarantee a stated interest rate for the term of the contracts. The crediting rate of security-backed contracts will track current market yields on a trailing basis. The rate reset allows the contract value to converge with the fair value of the underlying portfolio over time, assuming the portfolio continues to earn the current yield for a period of time equal to the current portfolio duration. The fair value of GICs is determined based on the present value of the contract's expected cash flows, discounted by current market interest rates for like duration and like quality investments. Synthetic GICs are portfolios of securities (debt securities or open end registered investment companies) owned by the Fund with wrap contracts that guarantee a fixed or variable rate for the term of the contracts.&lt;/span&gt;
