1. Description of Plan

Plan Description

The following description of The Manitowoc Company, Inc. 401(k) Retirement Plan (the "Plan") provides only general information. Participants should refer to the Plan Agreement for a more complete description of the Plan's provisions.

General

The Plan is a defined contribution profit-sharing plan covering substantially all salaried and hourly employees of participating companies of The Manitowoc Company, Inc. (the "Company"). Participating companies include the Company and all U.S. subsidiaries and affiliates of the Company, as defined in the Plan. The Plan is subject to the provisions of the Employee Retirement Income Security Act of 1974 ("ERISA"). The Company Retirement Plan Committee (the "Committee") is responsible for oversight of the Plan. The Committee determines the appropriateness of the Plan's investment offerings, monitors investment performance, and reports to the Board of Directors.

Contributions

Employees are automatically entered into the Plan after meeting the applicable eligibility requirements, with a deferral of 5% of their compensation unless they affirmatively elect an alternative deferral amount or elect not to participate in the Plan. Participants may elect to change this deferral to an alternative amount by electing a deferral between 0% to 75% of eligible compensation up to a maximum contribution subject to limitations established by the Internal Revenue Service ("IRS"). Participants who have attained age 50 before the end of the plan year are eligible to make catch-up contributions. The Plan allows direct rollovers from other qualified plans. Rollovers are not matched.

The Company provides a safe harbor matching contribution for non-union employees equal to 100% of the first 3% of contributed compensation and 50% of the next 2%, which vests immediately. For certain union employees, the Company provides a safe harbor match of either 100% of the first 3% of contributed compensation or 100% of the first 3% and 50% of the next 2%, depending on the applicable union agreement. In addition, the Company makes an annual non-elective contribution for union employees and may provide a discretionary profit-sharing contribution for non-union employees. For the year ended December 31, 2025, the Company made non-elective contributions of $148,554 for union employees and did not make a profit-sharing contribution for non-union employees. The safe harbor match true-up for 2025 totaled $165,559. Total employer contributions to a participant's account are limited to the lesser of 100% of the participant's annual compensation or the maximum amount permitted under IRS regulations.

Participants' Accounts

Each participant's account is credited with the participant's contributions, the Company's contributions, an allocation of plan earnings/losses, and is reduced for participant's withdrawals, investment expenses (based on account balances and participant investment elections), and an allocation of recordkeeping and administrative expenses. The benefit to which a participant is entitled is the benefit that can be provided from the participant's vested account.

Vesting

All employee contributions, the Company matching contributions, and associated earnings are immediately vested.

Discretionary profit-sharing and non-elective contributions vest at a rate of 20% per year, with participants becoming fully vested after five years of service. Participants who have not attained 5 years of service and leave the Company because of reaching age 65, or due to disability, or death, are considered to be 100% vested.

Voting Rights on The Manitowoc Company, Inc. Common Stock ("Company Stock")

Voting rights for all participants who own Company Stock in their account shall be determined in accordance with Code Section 409(e)(2). As provided under Code Section 409(e)(2), each participant in the Plan is entitled to direct the Trustee as to

the manner in which to vote all whole shares of Company Stock which are entitled to vote and are allocated in the account of such participant. As required under ERISA, the Trustee shall vote all such shares in accordance with those instructions. Votes representing fractional shares of stock shall be voted in the same ratio for and against each issue, as the applicable vote directed by participants with respect to whole shares of stock. Shares of Company Stock owned by the Plan, but not voted by the participant to whose account such shares have been allocated shall be voted by the Trustee in its absolute discretion.

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 vested account balance. The notes are secured by the balance in the participant's account and bear interest at prime plus 1%. Interest rates on existing loans within the Plan as of December 31, 2025, ranged from 4.25% to 9.50%. Notes are repaid through payroll deductions over a period not to exceed five years.

Payment of Benefits

Plan benefits are available at normal retirement age (age 65), disability, retirement, death, or termination of employment with vested interests. Benefits are payable in one lump sum, direct rollover, partial withdrawals, or installment payments. In addition, hardship distributions out of the participant's voluntary contributions account are permitted if certain criteria are met. The Plan also allows for in-service distributions upon attaining age 59½. Distributions may be made as soon as administratively feasible. The benefits are recorded when paid.

Forfeitures

As of December 31, 2025 and 2024, the forfeited non-vested account totaled $65,716 and $261,471, respectively. This account can be used to reduce future employer contributions. During 2025 and 2024, employer contributions were reduced by $230,419 and $220,000, respectively, from forfeited non-vested accounts. Forfeitures can also be used to offset plan expenses. During 2025 and 2024, forfeitures used to offset plan expenses were $68,702 and $63,465, respectively.

2. Summary of Significant Accounting Policies

3. Fair Value Measurement

Accounting Standards Codification ("ASC") Topic 820-10 defines fair value as 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. ASC Topic 820-10 classifies the inputs used to measure fair value into the following hierarchy:

Level 1 Unadjusted quoted prices in active markets for identical assets or liabilities

Level 2 Unadjusted quoted prices in active markets for similar assets or liabilities, or

Unadjusted quoted prices for identical or similar assets or liabilities in markets that are not active, or

Inputs other than quoted prices that are observable for the asset or liability

Level 3 Unobservable inputs for the asset or liability

The fair value measurement level within the fair value hierarchy of an asset or liability 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.

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

Mutual funds: Mutual funds consist of publicly traded funds of registered investment companies. The fair value of these investments is determined by the underlying securities of the mutual funds and valued as Level 1 within the valuation hierarchy.

Company Stock: The Manitowoc Company, Inc common stock is based on the unadjusted quoted market price. The fair value of the stock is classified as Level 1 within the valuation hierarchy.

Common collective trust funds: Valued at the net asset value ("NAV") of units held by the Plan at year-end, provided by the administrator of the fund. The NAV is based on the value of the underlying assets of the fund, minus its liabilities, and then divided by the number of units outstanding. The NAV's unit price is quoted on a private market that is not active; however, the unit price is based on underlying investments which are traded on an active market.

Fidelity Brokerage Link: This self-directed option allows participants to invest in mutual funds, common stocks, and other investment options beyond the investment options offered directly through the Plan. Such investments are classified based on the observable inputs of the underlying securities.

The following table sets forth additional disclosures of the Plan's investments whose fair value is estimated using net asset value per share as of December 31, 2025:

5. Party-in-Interest Transactions

Transactions involving the Company Stock and notes receivable from participants are considered party-in-interest transactions. These transactions are not, however, considered prohibited transactions under 29 CFR 408(b) of ERISA regulations.

As of December 31, 2025 and 2024, the Plan held 599,586 and 645,120 shares of the Company Stock, respectively. The Company did not declare a dividend in 2025 or 2024.

During the years ended December 31, 2025 and 2024, purchases of shares by the Plan totaled $748,619 and $798,903, respectively, and sales of shares by the Plan totaled $1,327,681 and $1,078,791, respectively.

Transactions involving investments administered by Fidelity, the Plan trustee, are considered party-in-interest transactions. These transactions are not, however, considered prohibited under ERISA regulations. As outlined in Note 2, "Summary of Significant Accounting Policies," the Plan paid certain expenses related to the Plan operations and investment activity to various service providers. These transactions qualify as party-in-interest transactions. These transactions are not, however, considered prohibited under ERISA regulations.

6. Plan Termination

The Company intends to continue the Plan indefinitely; however, the Company reserves the right to terminate the Plan at any time. In the event of termination, all amounts credited to participants' accounts shall become 100% vested and distributed to participants in accordance with the Plan's provisions.

7. Tax-Exempt Status of the Plan

On June 30, 2020, the IRS declared that the Plan is qualified pursuant to Section 401 of the Internal Revenue Code (IRC). Plan management believes any amendments and events since the effective date of the last IRS determination letter do not affect the qualified status of the Plan. Accordingly, the Plan is exempt from federal and state income taxes under current provisions of their respective laws.

9. Risks and Uncertainties

The Plan's investments 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 statements of net assets available for benefits.
