RPM International Inc. Union 401(k) Trust and Plan
Medina, Ohio
Opinion on the Financial Statements
We have audited the accompanying statements of net assets available for benefits of the RPM International Inc. Union 401(k) Trust and 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 (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 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 risk 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 the Plan’s 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 in the accompanying ERISA-required Supplemental Schedule H, line
4i-
Schedule of Assets (Held at End of Year) as of December 31, 2025 has been subjected to audit 1
procedures performed in conjunction with the audit of the Plan’s financial statements. The supplemental information is presented for the purpose of additional analysis and is not a required part of the financial statements but included supplemental information required by the Department of Labor’s Rules and Regulations for Reporting and Disclosure under the Employee Retirement Income Security Act of 1974. 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.

RPM INTERNATIONAL INC. UNION 401(k) TRUST AND PLAN
NOTE A - Description of the Plan
The following description of the Plan provides only general information. Participants should refer to the Plan document for a more complete description of the Plan’s provisions.
General
The Plan, adopted on February 1, 1997, is a defined contribution retirement savings plan covering certain union employees at several wholly owned domestic subsidiaries of RPM International Inc. (the Company and Plan Sponsor). The Plan is subject to the Employee Retirement Income Security Act of 1974 (ERISA), as amended.
Eligibility
Contributions
Participants may contribute up to 50 % of gross annual compensation, as defined. Participants who have attained age 50 before the end of the Plan year are eligible to make 20 % per contribution in the Company common stock. The Company matches, depending upon the collective bargaining agreement of each participating union, up to a maximum rate of 100% of the first 3% and 50% of the next 2% of participant deferrals. The matching Company contribution is invested in the same way the participants invest their own contributions. Contributions are subject to certain limitations, as defined.
catch-up
contributions. Participants may also contribute amounts representing distributions from other qualified defined benefit or defined contribution plans. Participants direct the investment of their contributions into various investment options offered by the Plan. The Plan currently offers a variety of investment funds as investment options for participants. Participants may invest up to a limit of Participant Accounts
Each participant’s account is credited with the participant’s contribution, the Company’s matching contribution and an allocation of Plan earnings/(losses) and charged with an allocation of administrative expenses. 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
Vesting is immediate for both employee and employer contributions and earnings thereon.
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. Participants can only have one loan outstanding under the Plan at any time. Loan terms may not exceed five years. The loans are secured by the balance in the participant’s account and bear interest of prime rate plus 1.00 %. Principal and interest are paid ratably through payroll deductions. Outstanding loans at December 31, 2025 bear interest rates between 4.25 % and 9.50 %.
RPM INTERNATIONAL INC. UNION 401(k) TRUST AND PLAN
NOTE A - Description of the Plan (continued)
Payment of Benefits
Upon termination of a participant’s employment, including termination by reason of death, disability or retirement, a participant may elect to receive either a
lump-sum
amount equal to the value of the participant’s interest in his or her accounts or regular installments over any period not to exceed ten years. In-service
withdrawals are available in certain limited circumstances, as defined by the Plan. Hardship withdrawals are allowed for participants incurring immediate and heavy financial need, as defined by the Plan. Hardship withdrawals are strictly regulated by the Internal Revenue Service (IRS). Plan Expenses
During 2025, certain administrative expenses and fees incurred in connection with the sale, purchase, and management of the assets of the investment funds were paid by the Plan.
The Company pays administrative costs associated with participant recordkeeping services for active
(non-terminated)
participants. Other fees, including individual participant transaction fees and administrative fees specific to terminated and retired participants are debited directly from the accounts of Plan participants. The Company participates in an arrangement that provides for the allocation of substantially all revenue sharing payments on certain funds to Plan participants. During 2025, the administrative expenses exceeded revenue sharing received during the calendar year by $6,083 . This amount is shown as Administrative Expenses on the accompanying statement of changes in net assets available for benefits. The Plan uses the forfeitures in accordance with the Plan document and during 2025 used available forfeitures to offset a portion of Plan recordkeeping fees. Forfeitures can come from
non-discrimination
testing failures, account balances for lost participants and uncashed checks. Transfer of Assets to and from the Plan
Assets are able to be transferred to and from the Company’s
Non-Union
and Union Plan, as employees change eligibility. Voting Rights
Each participant is entitled to exercise voting rights attributable to the shares of RPM International Inc. common stock allocated to the participant’s account. The RPM International Inc. Plan Committee is not permitted to vote any share for a participant. The trustee votes shares for which a participant has given no instructions in proportion to how instructed shares voted.
NOTE B - Summary of Significant Accounting Policies
Basis of Presentation
The accompanying financial statements of the RPM International Inc. Union 401(k) Trust and Plan (the Plan) have been prepared on the accrual basis in conformity with accounting principles generally accepted in the United States of America.
RPM INTERNATIONAL INC. UNION 401(k) TRUST AND PLAN
NOTE B - Summary of Significant Accounting Policies (continued)
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 C for discussion of fair value measurements.
Purchases and sales of securities are recorded on a trade-date basis. Interest income is recorded when received. 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 Plan year. Notes Receivable from Participant Accounts
Notes receivable from participants are measured at their unpaid principal balance plus any accrued but unpaid interest. Delinquent participant loans are reclassified as distributions based upon the terms of the Plan document.
Contributions
Participant contributions and any related employer matching contributions are recognized in the period during which the Company makes the respective payroll deduction from the participant’s compensation.
Payment of Benefits
Benefits are recorded when paid.
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 and assumptions that affect the reported amounts of assets, liabilities and changes therein, and the disclosure of contingent assets and liabilities. Actual results could differ from those estimates.
NOTE C - Fair Value Measurements
The Plan follows the provisions of Accounting Standards Codification (ASC) 820, which defines fair value and provides guidance for measuring fair value and expands disclosures about fair value measurements.
Fair Value Measurements and Disclosures,
Fair Value Measurements and Disclosures
RPM INTERNATIONAL INC. UNION 401(k) TRUST AND PLAN
NOTE C - Fair Value Measurements (continued)
| 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 inputs 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. There have been no changes in the methodologies used at December 31, 2025 and 2024.

NOTE C - Fair Value Measurements (continued)
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 tables set forth by level, within the fair value hierarchy, the Plan’s investments at fair value:

NOTE D - Plan Termination
Although it has not expressed any intent to do so, the Company has the right under the Plan to discontinue its contributions at any time and to terminate the Plan subject to the provisions of ERISA. Any unallocated assets of the Plan shall be allocated to participant accounts and distributed in such a manner as determined by the Company.
NOTE E - Income Tax Status
The Plan obtained its latest determination letter on December 17, 2014, in which the IRS stated that the Plan, as then designed, was in compliance with the applicable requirements of the Internal Revenue Code (IRC). Although the Plan document has been amended since receiving the determination letter, the Plan Administrator believes that the Plan and related trust are designed and are currently being operated in compliance with applicable requirements of the IRC and, therefore, believes the Plan is qualified, and the related trust is tax exempt.
Generally accepted accounting principles require Plan management to evaluate tax positions taken by the Plan and recognize a tax liability (or asset) if the Plan has taken an uncertain position that more likely than not would not be sustained upon examination by the tax authorities. The Plan is subject to routine audits by taxing jurisdictions; however, there are currently no audits for any tax periods in progress.
NOTE F - Related Party and Transactions
Parties-in-Interest
Fidelity Management Trust Company (FMTC) is the Plan trustee. Certain Plan investments are managed by FMTC, and therefore, these transactions qualify as transactions. Notes receivable from participants are also considered transactions. As described in Note A, the Plan paid certain expenses related to plan operations and investment activity to various service providers. The plan also issues loans to participants which are secured by the vested balance of the participants’ accounts. These transactions are transactions, which are exempt from prohibited transaction rules.

In addition, at December 31, 2025, the Plan held 6,080 shares of RPM International Inc. common stock valued at $633,708 . During 2025, there were purchases of $22,170 , sales of $160,418 , and interest and dividend income of $14,232 for RPM International Inc. common stock. At December 31, 2024, the Plan held 7,122 shares of RPM International Inc. common stock valued at $877,702 .
Transactions involving these investments are allowable transactions under ERISA.

NOTE G - 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 statements of net assets available for benefits.
