**REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM**

To the Pension Committee and Participants of

Mettler-Toledo, LLC Enhanced Retirement Savings Plan

Columbus, Ohio

**Opinion on the Financial Statements** 

We have audited the accompanying statements of net assets available for benefits (modified cash basis) of the Mettler-Toledo, LLC Enhanced Retirement Savings Plan (the Plan) as of December 31, 2025 and 2024, and the related statements of changes in net assets available for benefits (modified cash basis) for the years ended December 31, 2025 and 2024, and the related notes and schedules (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 (modified cash basis) of the Plan as of December 31, 2025 and 2024, and the changes in net assets available for benefits (modified cash basis) for the years ended December 31, 2025 and 2024, in conformity with the modified cash basis of accounting.

As described in Note 2, the accompanying financial statements and supplemental schedules were prepared on a modified cash basis of accounting, which is a comprehensive basis of accounting other than 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 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. 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.

**Supplemental Information**

The supplemental information contained in the schedule of assets held (modified cash basis) as of December 31, 2025 and the schedule of delinquent participant contributions (modified cash basis) for the year ended December 31, 2025 have been subjected to audit procedures performed in conjunction

------

<u>[**Table of Contents**](#ib843201ec8734e26a8220ddea9debe95_7)</u>

with the audit of the Plan's financial statements. The supplemental information is the responsibility of the Plan's management. Our audit procedures included determining whether the supplemental information reconciles to the financial statements or the underlying accounting and other records, as applicable, and performing procedures to test the completeness and accuracy of the information presented in the supplemental information. In forming our opinion on the supplemental information, we evaluated whether the supplemental information, including its form and content, is presented in conformity with the Department of Labor's Rules and Regulations for Reporting and Disclosure under the Employee Retirement Income Security Act of 1974. In our opinion, the supplemental information is fairly stated, in all material respects, in relation to the financial statements as a whole.

/s/ Clark, Schaefer, Hackett & Co.

We have served as the Plan's auditor since December 31, 2003.

Columbus, Ohio&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;

**Mettler-Toledo, LLC Enhanced Retirement Savings Plan**

**Notes to the Financial Statements**

**For the Years Ended December 31, 2025 and 2024**

**1. Description of Plan** 

The following description of the Mettler-Toledo, LLC Enhanced Retirement Savings Plan (the Plan) provides only general information. Participants should refer to the Summary Plan Description for a more complete description of the Plan's provisions.

**General** 

The Plan is a qualified defined contribution plan covering eligible employees of adopting units (wholly-owned subsidiaries) and a safe harbor 401(k)/401(m) plan under IRC 401(k)(12) and 401(m)(11). It is subject to the provisions of the Employee Retirement Income Security Act of 1974 (ERISA), as amended. Employees become eligible to participate in the Plan on the first day of a payroll period following the date the employee meets the eligibility requirements, as defined.

Mettler-Toledo, LLC (a wholly-owned subsidiary of Mettler-Toledo International Inc.) is both the Plan Sponsor and Administrator and is responsible for keeping accurate and complete records with regard to the Plan, informing participants of changes or amendments to the Plan, and ensuring that the Plan conforms to applicable laws and regulations. Vanguard Fiduciary Trust Company (VFTC) is the trustee and maintains the Plan assets.

**Contributions** 

Each year, participants may contribute up to 60% of pretax annual compensation, as defined by the Plan. Participants who reach age 50 may elect to make catch-up contributions. Participants are automatically enrolled in the Plan at 3% unless another election is made by the participant. Participants may also contribute rollover contributions representing distributions from other qualified plans. Forfeitures may be used by the Plan Sponsor to reduce future contributions and/or to pay reasonable Plan expenses.

The Plan Sponsor contributes:

Safe Harbor Matching Contributions - 100% of the first 3% of each participant's deferred compensation and 50% of the next 3% of each participant's deferred compensation. All participants who make contributions are eligible for the matching contributions.

Discretionary Contributions - Employees become eligible on their one-year anniversary of employment. Participants must be employed on the last day of the Plan year to receive this discretionary contribution, with the exceptions of death, retirement, disability, or authorized leave.

**Participant Accounts** 

Each participant's account is credited with the contributions made to the Plan on behalf of the participant and adjusted for earnings and losses thereon. Allocations of Plan earnings and losses are based on the investment options selected by the participant and their related account balance and

**Mettler-Toledo, LLC Enhanced Retirement Savings Plan**

**Notes to the Financial Statements**

**For the Years Ended December 31, 2025 and 2024**

allocated to each participant's account on a daily basis. The benefit to which a participant is entitled is the vested amount that is in such participant's account at any given time.

**Vesting** 

Participants are immediately vested in the Plan Sponsor's Safe Harbor Matching Contributions and the Plan Sponsor's Discretionary Contributions.

**Investment Options** 

Upon enrollment in the Plan, a participant can direct employee and employer contributions in 1% increments among the various investment options offered through VFTC, or into a self-directed brokerage option. This is a self-directed program that allows participants to invest their account balances in mutual funds that are outside the current plan options. A participant may elect to transfer amounts between investment options as of any business day. Certain investment options offered within the VFTC may not be directly transferred to the self-directed brokerage option for a period of 90 days.

**Company Stock Fund**

The Plan invests in an employer stock fund consisting of Mettler-Toledo International Inc. Common Stock (Company Stock). The fund may also hold cash or cash equivalents as necessary to satisfy obligations of the fund.

**Payment of Benefits** 

A participant's vested account may be distributed upon retirement, termination, disability or death. Distributions are made in lump-sum or equal annual installments not to exceed the employee's life expectancy. Upon death, the remaining balance shall be distributed in a lump sum within five years. Forfeitures, if any, are used to reduce the Plan Sponsor's contributions or pay Plan expenses. Participants may make a withdrawal during employment due to hardship as well as other allowable situations defined in the Plan document. Hardship withdrawals must meet the criteria for hardship under Section 401(k) of the Internal Revenue Code (IRC).

**Notes to the Financial Statements**

**For the Years Ended December 31, 2025 and 2024**

**2. Summary of Significant Accounting Policies** 

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

**Basis of Presentation** 

The accompanying financial statements of the Plan have been prepared on the modified cash basis of accounting, which is a comprehensive basis of accounting other than accounting principles generally accepted in the United States of America (U.S. GAAP). The difference between the modified cash basis and accounting principles generally accepted in the United States of America is that contributions and interest and dividend income are recognized when received and administrative expenses are recognized when paid.

**Investment Valuation and Income Recognition** 

Under the terms of a trust agreement between the Plan Sponsor and VFTC, the trustee invests trust assets at the direction of the plan participants. The trustee has reported to the Plan Sponsor the trust fund investments and the trust transactions at fair value. Shares of registered investment companies are valued at quoted market prices, which represent the net asset value of shares held by the Plan at year-end. The Plan's interest in the units of a common collective trust are based on information reported by VFTC using audited financial statements of the collective trust at the end of 2025 and 2024. The Company stock fund is valued at its year-end unit closing price (comprised of year-end market price plus uninvested cash position). Realized and unrealized gains and losses are reflected as net appreciation in fair value of investments in the statements of changes in net assets available for benefits.

Purchases and sales of securities are recorded on a trade-date basis. Interest and dividend income is recognized when received. Capital gain distributions are included in dividend income.

**Participant Loan Receivables** 

Participant loan receivables are measured at their unpaid principal balance plus any accrued but unpaid interest. Interest income is recognized when received. The interest rate for the life of the loan is set quarterly at the prime rate plus 1% as of the beginning of the quarter. Loans may not exceed the lesser of 50% of a participant's vested account balance or $50,000. The repayment period may not exceed five years. Each loan is secured by the remaining balance in the participant's account. A loan is considered delinquent after 60 days of not receiving a payment. The Plan reviews delinquent loans on a quarterly basis. As of December 31, 2025 and 2024, no loans were considered delinquent.

**Contributions** 

Participant and Plan Sponsor contributions are recognized when received by the trustee.

**Payment of Benefits** 

Benefits are recognized when paid.

**Mettler-Toledo, LLC Enhanced Retirement Savings Plan**

**Notes to the Financial Statements**

**For the Years Ended December 31, 2025 and 2024**

**Administrative Expenses** 

Fees for portfolio management of VFTC funds are paid directly from fund earnings. Administration fees and fees related to the administration of participant loan receivables are charged to the participant's account. Audit fees are either paid by the Plan Sponsor or from the forfeiture account. Should the Plan Sponsor elect not to pay all or part of such expenses, the trustee then pays these expenses from the Plan assets. Expenses are recognized when paid.

**Use of Estimates** 

The preparation of the Plan's financial statements in conformity with a modified cash basis of accounting, which is a comprehensive basis of accounting other than accounting principles generally accepted in the United States of America, requires the Plan Administrator to make certain estimates and assumptions that affect the reported amounts of net assets available for benefits and, when applicable, disclosure of contingent assets and liabilities at the date of the financial statements and the amounts of changes in net assets available for benefits during the reporting period. Actual results could differ significantly from those estimates.

**Risk and Uncertainties** 

The Plan provides various investment options in any combination of stocks, mutual funds, and other 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 statements of net assets available for benefits.

**For the Years Ended December 31, 2025 and 2024**

**3. Fair Value Measurements**

Under U.S. GAAP, fair value is defined 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. A fair value measurement consists of observable and unobservable inputs that reflect the assumptions that a market participant would use in pricing an asset or liability.

A fair value hierarchy has been established that categorizes these inputs into three levels:

Level 1:&nbsp;&nbsp;&nbsp;&nbsp;Quoted prices in active markets for identical assets and liabilities

Level 2:&nbsp;&nbsp;&nbsp;&nbsp;Observable inputs other than quoted prices in active markets for identical assets

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;and liabilities

Level 3:&nbsp;&nbsp;&nbsp;&nbsp;Unobservable inputs

Investments consist of various mutual funds, common collective trusts and a Company stock fund. The plan invests in shares of open-ended mutual funds that trade in active markets and produce a daily net asset value, equal to the fair value of the shares at year-end. Units of the common collective trusts are valued at net asset value at the end of the year. The NAV, as provided by the trustee, is used as a practical expedient to estimate fair value. The NAV is based on the fair value of the underlying investments held by the fund less its liabilities. This practical expedient would not be used if it is determined to be probable that the fund will sell the investment for an amount different from the reported NAV. Participant transactions (purchases and sales) may occur daily. If the Plan were to initiate a full redemption of the collective trusts, the investment advisor reserves the right to temporarily delay withdrawal from the trusts in order to ensure the securities liquidations will be carried out in an orderly business manner. There are no unfunded commitments related to the common collective trusts and units of the common collective trusts are redeemable at net asset value. Company stock is valued at its year-end unit closing price (comprised of year-end market price plus uninvested cash position).

The following tables present for each of these hierarchy levels, the Plan assets that are measured at fair value on a recurring basis at December 31:

Investments are measured using the net asset value (NAV) per share practical expedient have not been categorized in the fair value hierarchy. The amounts presented above are intended to permit reconciliation of the fair value hierarchy to the fair value of total plan assets in order to determine the amounts included in the Statement of Net Assets Available for Benefits.*

**4. Transactions with Parties-in-Interest** 

The Plan invests in shares of mutual funds and a common collective trust managed by an affiliate of VFTC. VFTC acts as trustee for only those investments as defined by the Plan. Transactions in such investments qualify as party-in-interest transactions which are exempt from the prohibited transaction rules.

Participants may select Company stock as an investment option. The amount of Company stock held at December 31, 2025 and 2024 was $22,386,167 and $21,702,696, respectively. The Company stock appreciated $2,811,050 and $407,697 in 2025 and 2024, respectively.

**5. Plan Termination** 

Although it has not expressed any intent to do so, the Plan Sponsor has the right under the Plan to discontinue its contributions at any time and to terminate the Plan subject to the provisions of ERISA. In the event of plan termination, participants will immediately become 100% vested in their accounts.

**6. Tax Status** 

The Plan adopted its current pre-approved plan which has received an opinion letter from the Internal Revenue Service (IRS) dated June 30, 2020, which indicates the plan was designed and in compliance with the applicable requirements of the IRC. Although The Plan has been amended since receiving the opinion letter, The Plan Administrator and the Plan's tax counsel believe that the Plan is currently designed and 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.
