REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Benefits Committee of the

Columbus McKinnon Corporation Employee Stock Ownership Plan:

Opinion on the Financial Statements

We have audited the accompanying statements of net assets available for benefits of the Columbus McKinnon Corporation Employee Stock Ownership Plan (the Plan), as of March 31, 2026 (in liquidation) and 2025, (ongoing), and the related statements of changes in net assets available for benefits for the years ended March 31, 2026 (in liquidation) and 2025, (ongoing), and the related notes (collectively referred to as the financial statements). In our opinion, the financial statements present fairly, in all material respects, the net assets available for benefits of the Columbus McKinnon Corporation Employee Stock Ownership Plan as of March 31, 2026 (in liquidation) and 2025, (ongoing), and the changes in net assets available for benefits for the years ended March 31, 2026 (in liquidation) and 2025, (ongoing), in accordance 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 the 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 audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. The Plan is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. As part of our audits, we are required to obtain an understanding of internal control over financial reporting, but not for the purpose of expressing an opinion on the effectiveness of the Plan’s internal control over financial reporting. Accordingly, we express no such opinion.

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. We believe that our audits provide a reasonable basis for our opinion.

Emphasis of Matter - Plan Termination and Liquidation Basis of Accounting

As discussed in Note 1 to the financial statements, the governing body of Columbus McKinnon Corporation Employee Stock Ownership Plan approved a plan of liquidation on August 4, 2025, and management determined liquidation is imminent. As a result, the Plan has changed its basis of accounting from the going concern basis used in presenting the 2025 financial statements to the liquidation basis used in presenting the 2026 financial statements. Our opinion is not modified with respect to this matter.

We have served as the Plan's auditor since 2006.

NOTES TO FINANCIAL STATEMENTS

MARCH 31, 2026 (IN LIQUIDATION) AND 2025 (ONGOING)

1. DESCRIPTION OF PLAN

The following brief description of the Columbus McKinnon Corporation Employee Stock Ownership Plan (ESOP or the Plan) is provided for general information purposes only. Participants should refer to plan documents for complete information.

Columbus McKinnon Corporation (the Company) established the Plan effective as of November 1, 1988. The Plan operates, in relevant parts, as an employee stock ownership plan and is designed to comply with section 4975(e)(7) and the regulations thereunder of the Internal Revenue Code of 1986, as amended (Code) and is subject to the applicable provisions of the Employee Retirement Income Security Act of 1974 (ERISA). Individuals appointed by the Company’s Board of Directors act as trustees to the Plan (the Trustee).

The Plan purchased Company common shares at various times and holds the stock in a trust established under the Plan. All shares were fully vested at March 31, 2026 and 2025. In August, 2025, the Board of Directors of Columbus McKinnon Corporation adopted resolutions to terminate the Columbus McKinnon Corporation Employee Stock Ownership Plan (the Plan). The Plan has been formally amended to adopt such resolution to terminate the Plan effective August 4, 2025. The ESOP previously became closed to new participants effective January 1, 2012. The final ESOP allocation was made to ESOP participants as of March 31, 2015, and all participants were 100% vested in their respective ESOP account balance as of that date. As a result of the ESOP termination, the vested account balance of each ESOP participant was distributed to such ESOP participants, who had the option either to have their vested account balance distributed to them directly or have their vested account balance rolled over to the Company's qualified 401(k) plan, an individual retirement account or other eligible retirement plan. As of March 31, 2026, all plan assets have been distributed in conjunction with the termination and liquidation of the plan.

A summary of the ESOP’s provisions is as follows:

Eligibility

Substantially all of the domestic nonunion employees of the Company and its domestic subsidiaries who have attained age 21 and have completed one year of service (minimum of 1,000 hours) are eligible to participate in the ESOP.

Effective December 31, 2011, the Plan was amended so that the term “eligible employee,” does not include any individual who is hired after December 31, 2011.

Contributions

Each plan year (each 12-month period ending March 31, prior to the Plan paying off a loan payable on July 1, 2014), the Company contributed to the ESOP for each participant (a) who was actively employed as an employee on December 31 and who earned at least 1,000 hours of service as an employee in the calendar year ending December 31, or (b) who terminated employment on or after January 1 during a plan year after attaining age 55 and completing at least five years of eligibility service. The final share allocation occurred during the year ended March 31, 2015; there will not be any further share contributions to the Plan. Contribution allocations are made in shares of Columbus McKinnon Corporation stock. Columbus McKinnon Corporation is the Plan sponsor, and therefore, these transactions and related dividend income qualify as party-in-interest transactions.

Vesting

All participant accounts were 100% vested effective December 31, 2014.

Payment of Benefits

Prior to the termination of the Plan, upon a participant’s termination, the value of his or her account was distributed if the value of the account was less than $1,000 or, at the participant’s option, either immediately or at any valuation date until retirement, as provided in the ESOP. A retiree may elect to defer distribution up to 73 years of age. The account of a participant who was not a 5% owner and who had not separated from service but had attained the age of 73 commenced distribution unless the participant elected to defer distribution until employment ceased. Valuation dates for distributions were September 30 or March 31.

During the year ended March 31, 2026, $2,013,412 which includes 104,505 shares, was distributed to vested participants in cash and stock certificates ($750,387 or 16,769 shares, distributed during the year ended March 31, 2025). As of March 31, 2025, $185,621 is included in the ESOP assets for terminated participants who had requested distributions and were awaiting the updated valuation at March 31, 2025, to receive them. No such amounts existed at March 31, 2026. Transfer to other qualified plans represent participant rollovers to another qualified retirement plan sponsored by Columbus McKinnon Corporation as part of the liquidation.

Participant Accounts

The Plan is a defined contribution plan under which a separate individual account was maintained for each participant. Prior to the Plan's termination, participant accounts were appropriately adjusted to reflect any increase or decrease in the fair market value of the Plan’s assets during the period.

Dividends

Dividends paid on stock allocated to a participant’s stock account will be allocated to the participant’s nonstock account. During the years ended March 31, 2026 and 2025 respectively, dividends of $37,700 and $40,692 were paid on the Company’s common stock, including shares held by the Plan.

Voting Rights

Each participant was entitled to exercise voting rights attributable to the shares were allocated to his or her account and was notified by the trustee prior to the time that such rights were to be exercised. The trustee was not permitted to vote any allocated share for which instructions had not been given by a participant.

Put Option

Pursuant to Federal income tax requirements, the Plan contained a put option that was exercisable by plan participants in situations where Company stock was no longer traded on an established securities market. Specifically, the put option provided participants with the right to require that the Company buy any shares of its stock distributed to participants when there was no market for the trading of such shares. The price paid in the event the put option was exercised was representative of the fair market value of such stock. If the distribution was a total distribution of the participant’s account, payment was made in five substantially equal annual payments, including interest. If the distribution was not a total distribution, payment was required to be made no later than 30 days after the participant exercises the put option.

Diversification

In accordance with the Plan document, employees who had attained 55 years of age and ten years of participation in the Plan had the option to diversify the investments in their stock accounts by selling a specified percentage of their shares at the current market value and transferring the sale proceeds to another defined contribution plan maintained by the Company. Diversification was offered to each eligible participant over a six-year period. In each of the first five years, a participant could diversify up to 25 percent of the number of post-1986 shares allocated to his or her account, less any shares previously diversified. In the sixth year, the percentage changes to 50 percent. The number of shares elected to be sold for diversification totaled 0 and 457 at March 31, 2026 and 2025, respectively. These diversification sales resulted in transfers being made to the Company’s Thrift 401(k) Plan totaling $0 and $16,106 for the years ended March 31, 2026 and 2025, respectively.

Plan Termination

On August 4, 2025, the Company adopted a resolution to terminate the Plan. In accordance with the terms of the Plan, all affected participants became fully vested in their account balances upon termination. The Plan's assets were subsequently distributed to participants and beneficiaries in accordance with the Plan document and applicable provisions of the Internal Revenue Code.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Cash

The Company maintains its cash in a bank money market account. The Company uses the balance in this account for transactions relating to diversification.

Basis of Accounting

The financial statements are prepared on the accrual basis of accounting in accordance with accounting principles generally accepted in the United States of America. As a result of management's resolution to terminate the Plan effective August 4, 2025 and liquidate the plan assets, as described in Note 1, the Plan changed its basis of accounting from the going concern basis to the liquidation basis for the year ended March 31, 2026. The liquidation basis of accounting presents assets at amounts expected to be realized in liquidation and liabilities at amounts expected to be paid. At March 31, 2026, there were no material

differences between amounts presented on the liquidation basis and those that would have been presented on the going concern basis.

Use of Estimates

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

Benefit Payments

Benefits are recorded when paid.

Investment Valuation and Income Recognition

The common shares of the Company are valued at fair value on March 31, 2026 and 2025. 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 5 for discussion of fair value measurements.

Purchases and sales of investments 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) in fair value of investments includes the Plan’s gains and losses on assets bought and sold as well as held during the year.

Risks and Uncertainties

The Plan invests in various 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 participants' account balances and the amounts reported in the statement of net assets available for benefits.

Administrative Expenses

Substantially all administrative expenses are paid by the Company.

3. ADMINISTRATION OF PLAN ASSETS

The Plan is administered by Blue Ridge ESOP Associates. The Plan's assets, which consist principally of Company common shares, were held by Equiniti Trust Company, LLC (Equiniti) for the years ending March 31, 2026 and 2025. Equiniti invests interest, dividend income and makes distributions to participants at the direction of Blue Ridge ESOP Associates.

Certain administrative functions are performed by officers or employees of the Company. No such officer or employee receives compensation from the Plan. Administrative expenses for Plan related fees are paid by the Company.

4. INVESTMENTS

The Plan's investments, at March 31, are presented in the following table:


	2026		2025
Columbus McKinnon Corporation stock:
Number of shares	—		142,867
Cost	$	—	$	1,846,989
Fair value	$	—	$	2,418,738

5. FAIR VALUE MEASUREMENTS

Financial Accounting Standards Board (FASB) Accounting Standards Codification 820 (ASC 820) establishes a 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 ASC 820 are described below:

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 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.

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.

Following is a description of the valuation methodologies used for assets measured at fair value:

Common Stocks: Quoted prices in principal active markets for identical assets as of the valuation date (Level 1).

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, while 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 following table sets forth by level, within the fair value hierarchy, the Plan's assets at fair value as of March 31, 2025:



	Level 1		Level 2		Level 3		Total
Columbus McKinnon Corporation stock	$	2,418,738	$	—	$	—	$	2,418,738
Total assets at fair value	$	2,418,738	$	—	$	—	$	2,418,738

6. INCOME TAX STATUS

The Plan obtained its latest determination letter on June 8, 2026, in which the Internal Revenue Service states that the plan, as then designed, was in compliance with the applicable requirements of the Internal Revenue Code.
