REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Directors, Plan Administrator, and Plan Participants

Orange County Bancorp, Inc. 401(K) Plan

Opinion on the Financial Statements

We have audited the accompanying statements of net assets available for benefits of Orange County Bancorp, Inc. 401(k) Plan (the Plan) as of December 31, 2025 and 2024, the related statement of changes in net assets available for benefits for the year ended December 31, 2025, and the related notes to the financial statements (collectively, the financial statements). In our opinion, the financial statements present fairly, in all material respects, the net assets available for benefits of the Plan as of December 31, 2025 and 2024, and the changes in net assets available for benefits for the year ended December 31, 2025, in conformity with accounting principles generally accepted in the United States of America.

Basis for Opinion

These financial statements are the responsibility of the Plan’s management. Our responsibility is to express an opinion on the Plan’s financial statements based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Plan in accordance with U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements.

NOTES TO FINANCIAL STATEMENTS AS OF DECEMBER 31, 2025 & 2024

AND FOR THE YEAR ENDED DECEMBER 31, 2025

NOTE A - DESCRIPTION OF PLAN

The following brief description of the Orange County Bancorp, Inc. 401(k) Plan (the “Plan”) is provided for general information purposes only. Participants should refer to the Plan agreement for more complete information.

General.

The Orange Bank & Trust Company (the “Bank”), formerly known as Orange County Bank and Trust Company established the Orange County Trust Company Employee Stock Ownership Plan with Section 401(k) Provisions effective as of January 1, 1993. As of January 1, 2016, the Orange County Trust Company Employee Stock Ownership Plan was amended and restated to provide for the transfer of the sponsorship of the Plan from Orange County Trust Company to Orange County Bancorp, Inc. and that the Plan allow for automatic enrollment for new hires and safe harbor non-elective contribution. It is intended that the Plan be a qualified profit-sharing plan within the meaning of Section 401(a) of the Internal Revenue Code of 1986, as amended (the “Code”), that the requirements of Code Sections 401(k) or 414(v) be satisfied as to that portion of the Plan applicable to Before-Tax Contributions, that the requirements of Code Section 401(m) be satisfied as to that portion of the Plan applicable to Employer Matching Contributions, and that the Trust or other funding vehicle associated with the Plan be exempt from Federal income tax pursuant to the provisions of Code Section 501(a). The Plan is intended to include a stock bonus plan qualified under Code Section 401(a) and a non-leveraged employee stock ownership plan (ESOP) satisfying the requirements of Code Sections 401(a), 409 and 4975e. The ESOP component of the Plan is designed to be invested primarily in employer securities within the meaning of Code Section 4975(e)(8) and such, the primary investment of the ESOP shall be the Orange County Bancorp, Inc. Stock Fund. The Plan is subject to the applicable provisions of the Employee Retirement Income Security Act of 1974, as amended (ERISA). The Plan was administered by Pentegra Services, Inc. (“Pentegra”) during 2024 and until November 2025. Beginning in November 2025, Principal Trust Company (“Principal”) became the administrator of the Plan. Empower Trust Company LLC was the recordkeeper between January and November 2025. During November 2025, the recordkeeping of the Plan was transferred and converted to Principal.

Eligibility.

Effective November 15, 2025, employees of the Bank who have attained the age of 18 are eligible to participate in the Plan and receive employer contributions after 6 months of service provided they have at least 500 hours of service. Prior to November 15, 2025, employees of the Bank who have attained the age of 18 were eligible to participate in the Plan after 6 months of service, provided they have at least 1000 hours of service. A Participant, prior to November 15, 2025, was eligible to receive Employer Matching Contributions and Discretionary Employer contributions upon attaining age of 21 and completing a year of service, provided they have at least 1,000 hours of service.

Contributions.

Each year, participants may contribute up to the annual maximum determined by the Internal Revenue Code, as defined in the Plan. Participants who have attained age 50 before the end of the Plan year are eligible to make catch-up contributions. The Plan allows for Pre-Tax and Roth Elective Deferrals. Participants may designate all or a portion of their deferrals as Roth Elective Deferrals. Each employee who becomes eligible to participate in the Plan after January 1, 2016 and who has not specifically elected to make salary reduction contributions will be automatically enrolled for pre-tax salary reduction contributions at a rate of 6% of base pay. Participants may also contribute amounts representing distributions from other qualified defined benefit or contribution plans. Participants direct the investment of their contributions into various investment options offered by the Plan. The Bank makes additional contributions to eligible participant accounts. Effective for Plan years beginning after January 1, 2016, to satisfy the requirements of IRC sections 401(k)(12), the Bank will make safe harbor non-elective contributions equal to 3% of eligible participants annual compensation.

Effective June 1, 2025, eligible participants receive employer matching contributions up to 4% of base compensation. Effective for Plan years beginning after January 1, 2016, to satisfy the requirements of IRC sections 401(k)(12), the Bank will make safe harbor non-elective contributions equal to 3% of eligible participants annual compensation.

Table of Contents

Participant Accounts

Each participant’s account is credited with the participant’s contribution and allocations of (a) the Bank’s contribution and, (b) Plan earnings (losses), and charged with an allocation of any administrative expenses paid by the Plan. Allocations are based on participant earnings or account balances, as defined. The benefit to which a participant is entitled is the benefit that can be provided from the participant’s vested account.

Vesting

Participants are immediately vested in before tax contributions, Roth contributions, rollover contributions, Employer’s safe harbor non-election contribution, Employer’s discretionary contributions and actual earnings thereon.

Vesting in any Employer’s matching contribution portion of the participant accounts is based on years of continuous service. Effective June 1, 2025, a participant is vested 33% a year and is 100% vested after three years of credited service. Prior to June 1, 2025, a participant was vested 20% a year and was 100% vested after five years of credited service.

Notes Receivable from Participants

Participants may borrow from their fund accounts a minimum of $1,000 up to a maximum equal to the lesser of $50,000 or 50% of their account balance. The notes are secured by the balance in the participant’s account and bear a reasonable interest rate equal to the prevailing rate charged by lenders for similar loans as determined by the Bank. The interest rates are between 4.25% and 9.50% as of December 31, 2025. Principal and interest are paid ratably through bi-weekly payroll deductions.

Payment of Benefits

On termination of service due to death, disability or retirement, a participant may elect to receive either a lump-sum amount equal to the value of the participant’s vested interest in his or her account or in monthly, quarterly, semiannual or annual installments; provided, however that such period shall not extend beyond the participant’s life expectancy or the life expectancy of the participant and his/her designated beneficiary.

Effective November 6, 2020, the Plan was amended to permit an automatic rollover of a participant’s vested account balance between $1,000 and $5,000 in the event the participant does not make a distribution election under the Plan.

In accordance with the Plan provisions, participants may make withdrawals from their accounts. To qualify for a withdrawal, participants must attain age 59-1/2, establish permanent or total disability, or demonstrate financial hardship as defined under the Plan.

Funds available for a hardship withdrawal are limited to a participant’s need and may not exceed the total of the participant’s contributions, certain Bank contributions, and earnings in the Plan as defined. Eligibility for a hardship withdrawal is defined as the need for uninsured medical expenses, purchase of a participant’s principal residence, payment of post-high school tuition, to prevent the loss of residence, payment for burial or funeral expenses for a parent, child, spouse or dependent, or expenses for the repair of damage to the employee’s principal residence under Internal Revenue Code Section 165.

Forfeited Accounts

At December 31, 2025 and 2024 forfeited non-vested account balances were $0. This account would be used to reduce future employer matching contributions to the plan and then to pay administrative expenses of the Plan. For the year ended December 31, 2025, administrative expenses were reduced by $1,574 from forfeited nonvested accounts.

Table of Contents

NOTE B - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

The following are the significant accounting policies followed by the Plan:

Basis of Accounting

The accompanying financial statements are prepared on the accrual basis of accounting.

Use of Estimates

The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires the Plan’s administrator to make estimates and assumptions that affect the reported amounts of assets and liabilities and changes therein, and disclosure of contingent assets and liabilities. Accordingly, actual results could differ from those estimates.

Investment Valuation and Income Recognition.

Investments are reported at fair value. Fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. See Note D for discussion of fair value measurements and see Note E for discussion of the fair value measurements of the ESOP components. Purchases and sales of securities are recorded on a trade-date basis. Interest income is recorded on the accrual basis. Dividends are recorded on the ex-dividend date. Net appreciation (depreciation) includes the Plan’s gains and losses on investments bought and sold as well as held during the year.

Payment of Benefits.

Benefit payments to participants are recorded upon distribution.

Notes Receivable From Participants

Notes receivable from participants are measured at their unpaid principal balance plus any accrued but unpaid interest. Interest income is recorded on the accrual basis. Related fees are recorded as administrative expenses and are expensed when they are incurred.

Contributions

Contributions from Plan participants and the matching contributions from the Bank are recorded in the year in which the employee contributions are withheld from compensation.

Operating Expenses.

Certain expenses of maintaining the Plan are paid by the Plan, unless otherwise paid by the Bank. Expenses that are paid by the Bank are excluded from these financial statements. Fees related to the administration of notes receivable from participants are charged directly to the participant’s account and are included in administrative expenses. Investment related expenses are included in net appreciation (depreciation) of fair value of investments.

NOTE C – TAX STATUS

The Plan adopted the Principal Financial Group ESOP/KSPO pre-approved plan, which received an opinion letter from the Internal Revenue Service (“IRS”) dated June 30, 2020, stating that the written form of the underlying volume submitter plan document is qualified under Section 401(a) and 4975(e)(7) of the IRC. Although the Plan has been amended since receiving the determination letter, the Plan administrator and the Plan’s tax counsel believe that the Plan is designed, and is currently being operated, in compliance with the applicable requirements of the IRC and, therefore, believe that the Plan is qualified, and the related trust is tax-exempt.

Accounting principles generally accepted in the United States of America require plan management to evaluate tax positions taken by the plan and recognize a tax liability if the plan has taken an uncertain position that more likely than not would not be sustained upon examination by the taxing authorities. The Plan is subject to routine audits by taxing jurisdictions; however, there are currently no audits

for any tax periods in progress. The Plan administrator believes it is no longer subject to income tax examinations for years prior to 2022.

NOTE D - FAIR VALUE MEASUREMENTS

The Plan’s investments are reported at fair value in the accompanying statements of net assets available for benefits. The methods used to measure fair value may produce an amount 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 measure the fair value of certain financial instruments could result in a different fair value at the reporting date.

Financial Accounting Standards Board (FASB) Accounting Standards Codification (ASC) Topic 820, Fair Value Measurements and Disclosures, provides the framework for measuring fair value. That framework provides a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (level 1 measurements) and the lowest priority to unobservable inputs (level 3 measurements). The three levels of the fair value hierarchy under FASB ASC 820 are described as follows:

Level 1: Inputs to the valuation methodology are unadjusted quoted prices for identical assets or liabilities in active markets that the Plan has the ability to access.

Level 2: Inputs to the valuation methodology include:

Quoted prices for similar assets or liabilities in active markets;
Quoted prices for identical or similar assets or liabilities in inactive markets;
Inputs other than quoted market prices that are observable for the asset or liability;
Inputs that are derived principally from or corroborated by observable market data by correlation or other means.

If the asset or liability has a specified (contractual) term, the Level 2 input must be observable for substantially the full term of the asset or liability.

Level 3: Inputs to the valuation methodology are unobservable and significant to the fair value measurement.

Following is a description of the valuation methodologies used for assets measured at fair value. There have been no changes in the methodologies used at December 31, 2025 and 2024.

The Mutual Funds are valued at the daily closing price as reported by the fund. Mutual funds held by the Plan are open-end mutual funds that are registered with the SEC. These funds are required to publish their daily net asset value (NAV) and to transact at that price. The mutual funds held by the Plan are deemed to be actively traded.
The Collective Investment Funds are valued at the NAV of the units held by the custodian at year end. Unit values are determined by dividing the funds’ net assets, which represent the unadjusted prices in active markets of the underlying investments, by the number of units outstanding at the valuation date. Participant transactions (purchases and sales) may occur daily. Were the Plan to initiate a full redemption of the collective investment fund, the investment adviser reserves the right to temporarily delay withdrawal from the fund in order to ensure that securities liquidations will be carried out in an orderly business manner.
The Orange County Bancorp, Inc. Stock Fund is a unitized stock fund. The fund consists of both Orange County Bancorp, Inc. common stock and a short-term cash component that provides liquidity for daily trading. Orange County Bancorp, Inc. common stock is valued at the quoted market price from a national securities exchange, and the short-term cash investment is valued at cost, which approximates fair value.

Table of Contents

The asset’s or liability’s fair value measurement level within the fair value hierarchy is based on the lowest level of any input that is significant to the fair value measurement. Valuation techniques used need to maximize the use of observable inputs and minimize the use of unobservable inputs.

All of the Plan’s investments are in a trust which was established for the investment of assets of the Plan. The assets of the trust are held by Principal, custodian of the Plan.

The following tables set forth by level, within the fair value hierarchy, the Plan’s assets at fair value for the periods indicated:

NOTE F – RISKS AND UNCERTAINTIES

The Plan invests in various investment securities as well as the Orange County Bancorp Inc. common stock. These 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 the amounts reported in the statement of net assets available for benefits.

NOTE G – ADMINISTRATION OF PLAN ASSETS

The Plan’s assets which consist of Orange County Bancorp, Inc. common stock, mutual funds, and various collective investment funds, were held and maintained by Reliance Trust Company through February 2024 and subsequently by Empower Trust Company, LLC, through November 15, 2025, and subsequently by Principal. Pentegra Services, Inc. was the third party administrator of the Plan through November 2025. During November 2025, Principal became the third-party administrator and the custodian of the Plan. Pentegra, and its successor Principal, in conjunction with the custodians noted above receive the participant contributions and invest the contributions to the participant accounts according to the investment allocation selected by the participant. Pentegra, and its successor Principal, in conjunction with the custodians maintained the participant accounts including processing distributions and advances and payments to participant loans.

Certain administrative functions are performed by the officers or employees of the Bank. No such officer or employee receives compensation from the Plan.

NOTE H – PLAN TERMINATION

Although it has not expressed any intent to do so, the Bank has the right under the Plan to fully or partially terminate the Plan subject to the provisions of ERISA at any time. In the event of Plan termination, participants would become 100% vested in their account balance.
