Accounting Policies [Abstract]
Consolidation, Noncontrolling Interests and Basis of Presentation	NOTE 1 — CONSOLIDATION, NONCONTROLLING INTERESTS AND BASIS OF PRESENTATION The accompanying unaudited Consolidated Financial Statements have been prepared in accordance with Generally Accepted Accounting Principles in the U.S. (“GAAP”) for interim financial information and the instructions to Form 10-Q. In our opinion, all adjustments (consisting of normal, recurring accruals) considered necessary for a fair presentation have been included for the three-month periods ended August 31, 2024 and 2023. For further information, refer to the Consolidated Financial Statements and Notes included in our Annual Report on Form 10-K for the year ended May 31, 2024. Our financial statements include all of our majority-owned subsidiaries. We account for our investments in less-than-majority-owned joint ventures, for which we have the ability to exercise significant influence, under the equity method. Effects of transactions between related companies are eliminated in consolidation. Noncontrolling interests are presented in our Consolidated Financial Statements as if parent company investors (controlling interests) and other minority investors (noncontrolling interests) in partially-owned subsidiaries have similar economic interests in a single entity. As a result, investments in noncontrolling interests are reported as equity in our Consolidated Financial Statements. Additionally, our Consolidated Financial Statements include 100 % of a controlled subsidiary’s earnings, rather than only our share. Transactions between the parent company and noncontrolling interests are reported in equity as transactions between stockholders, provided that these transactions do not create a change in control. Our business is dependent on external weather factors. Historically, we have experienced strong sales and net income in our first, second and fourth fiscal quarters comprising the three-month periods ending August 31, November 30, and May 31, respectively, with weaker performance in our third fiscal quarter (December through February).

Accounting Changes and Error Corrections [Abstract]
New Accounting Pronouncements	NOTE 2 — NEW ACCOUNTING PRONOUNCEMENTS New Pronouncements Adopted In September 2022, the Financial Accounting Standards Board ("FASB") issued Accounting Standard Update ("ASU") 2022-04, "Liabilities - Supplier Finance Programs (Subtopic 405-50)," which is intended to establish disclosures that enhance the transparency of a supplier finance program used by an entity in connection with the purchase of goods and services. This guidance requires annual and interim disclosure of the key terms of outstanding supplier finance programs, the amount outstanding under such programs including where they are recorded on the balance sheet, and a roll-forward of the related obligations. The new standard does not affect the recognition, measurement, or financial statement presentation of the supplier finance program obligations. These amendments are effective for fiscal years beginning after December 15, 2022, except for the amendment on roll-forward information, which is effective for fiscal years beginning after December 15, 2023. We adopted the new standard on June 1, 2023 , on a retrospective basis other than the roll-forward guidance, which we plan to adopt on a prospective basis beginning with our fiscal 2025 annual financial statements. As of adoption on June 1, 2023, we did no t have any material supplier finance program obligations; however, we began such an arrangement during the fourth quarter of fiscal 2024. Refer to Note 14, “Supply Chain Financing,” to the Consolidated Financial Statements. New Pronouncements Issued In December 2023, the FASB issued ASU 2023-09, "Income Taxes (Topic 740): Improvements to Income Tax Disclosures," which requires a public business entity to disclose specific categories in its annual effective tax rate reconciliation and disaggregated information about significant reconciling items by jurisdiction and by nature. The ASU also requires entities to disclose their income tax payments (net of refunds) to international, federal, and state and local jurisdictions. The guidance makes several other changes to income tax disclosure requirements. This guidance is effective for fiscal years beginning after December 15, 2024, and requires prospective application with the option to apply it retrospectively. Early adoption is permitted. We are currently evaluating this ASU to determine its impact on our disclosures. In November 2023, the FASB issued ASU 2023-07, "Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures," which expands disclosures about a public business entity's reportable segments and provides for more detailed information about a reportable segment's expenses. This guidance is effective for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024, and requires retrospective application to all prior periods presented in the financial statements. Early adoption is permitted. We are currently evaluating this ASU to determine its impact on our disclosures.

Restructuring

Restructuring and Related Activities [Abstract]
Restructuring	NOTE 3 — RESTRUCTURING We record restructuring charges associated with management-approved restructuring plans to either reorganize one or more of our business segments, or to remove duplicative headcount and infrastructure associated with our businesses. Restructuring charges can include severance costs to eliminate a specified number of associates, infrastructure charges to vacate facilities and consolidate operations, contract cancellation costs and other costs. We record the short-term portion of our restructuring liability in other accrued liabilities and the long-term portion, if any, in other long-term liabilities in our Consolidated Balance Sheets. In August 2022, we approved and announced our Margin Achievement Plan 2025 (“MAP 2025”), which is a multi-year restructuring plan designed to improve margins by streamlining business processes, reducing working capital, implementing commercial initiatives to drive improved mix, pricing discipline and salesforce effectiveness and improving operating efficiency. Most activities under MAP 2025 are anticipated to be completed by the end of fiscal 2025; however, we expect some costs to extend beyond this date. The current total expected costs associated with this plan are outlined below and decreased approximately $ 10.9 million compared to our prior quarter estimate, attributable to decreases in expected facility closure and other related costs of $ 13.0 million and increases in expected severance and benefit charges of $ 2.1 million. Throughout our MAP 2025 initiative, we will continue to assess and find areas of improvement and cost savings. As such, the final implementation of the aforementioned phases and total expected costs are subject to change. USL Restructuring During the quarter ended August 31, 2023, we recognized a loss on sale of $ 4.5 million in connection with the divestiture of USL’s Bridgecare services division. The Bridgecare division was a contracting business focused on the installation of joints and waterproofing in the UK. The loss on this sale was included in selling, general and administrative ("SG&A") expenses in our Consolidated Statements of Income and net loss on sales of assets and businesses in our Consolidated Statements of Cash Flows. Additionally, during the quarter ended August 31, 2023, in connection with MAP 2025, we realigned certain businesses and management structures within our segments. Within our PCG segment, certain businesses of our USL reporting unit were transferred to our Fibergrate, Carboline and Stonhard reporting units. As a result of this change in our market strategy, we performed an interim impairment assessment of the USL indefinite-lived tradename. Calculating the fair value of the USL’s indefinite-lived tradename required the use of various estimates and assumptions. We estimated the fair value of USL’s indefinite-lived tradename by applying a relief-from-royalty calculation, which included discounted future cash flows related to projected revenues impacted by this decision. In applying this methodology, we relied on a number of factors, including actual and forecasted revenues and market data. As the carrying amount of the tradename exceeded its fair value, an impairment loss of $ 3.3 million was recorded for the three months ended August 31, 2023. This impairment loss was classified as restructuring expense within our PCG segment. Following is a summary of the charges recorded in connection with MAP 2025 by reportable segment for the three-month periods ending August 31, 2024 and 2023, as well as the total expected costs related to projects identified to date: Three Months Three Months Cumulative Total (In thousands) August 31, 2024 August 31, 2023 to Date Costs Construction Products Group ("CPG") Segment: Severance and benefit costs $ 890 $ 415 $ 16,093 $ 20,037 Facility closure and other related costs 376 - 984 6,715 Total Charges $ 1,266 $ 415 $ 17,077 $ 26,752 Performance Coatings Group ("PCG") Segment: Severance and benefit costs $ 150 $ 831 $ 4,009 $ 5,669 Facility closure and other related costs 5 30 177 1,435 Other restructuring costs (a) - 4,555 7,092 7,092 Total Charges $ 155 $ 5,416 $ 11,278 $ 14,196 Consumer Segment: Severance and benefit costs $ 3,938 $ - $ 13,711 $ 17,826 Facility closure and other related costs 20 14 797 2,726 Total Charges $ 3,958 $ 14 $ 14,508 $ 20,552 Specialty Products Group ("SPG") Segment: Severance and benefit costs $ 1,481 $ 653 $ 5,180 $ 5,220 Facility closure and other related costs 342 - 877 3,978 Total Charges $ 1,823 $ 653 $ 6,057 $ 9,198 Corporate/Other Segment: Severance and benefit (credits) $ - $ - $ ( 50 ) $ ( 50 ) Total Charges $ - $ - $ ( 50 ) $ ( 50 ) Consolidated: Severance and benefit costs $ 6,459 $ 1,899 $ 38,943 $ 48,702 Facility closure and other related costs 743 44 2,835 14,854 Other restructuring costs - 4,555 7,092 7,092 Total Charges $ 7,202 $ 6,498 $ 48,870 $ 70,648 (a) Of the $ 4.6 million of other restructuring costs incurred for the three-month period ending August 31, 2023, $ 3.3 million is associated with the impairment of an indefinite-lived tradename as described above.

Fair Value Measurements

Fair Value Disclosures [Abstract]
Fair Value Measurements	NOTE 4 — FAIR VALUE MEASUREMENTS Financial instruments recorded in the Consolidated Balance Sheets include cash and cash equivalents, trade accounts receivable, marketable securities, notes and accounts payable, and debt. An allowance for credit losses is established for trade accounts receivable using assessments of current creditworthiness of customers, historical collection experience, the aging of receivables and other currently available evidence. Trade accounts receivable balances are written-off against the allowance if a final determination of uncollectibility is made. All provisions for allowance for doubtful collection of accounts are included in SG&A expense. The valuation techniques utilized for establishing the fair values of assets and liabilities are based on observable and unobservable inputs. Observable inputs reflect readily obtainable data from independent sources, while unobservable inputs reflect management’s market assumptions. The fair value hierarchy has three levels based on the reliability of the inputs used to determine fair value, as follows: Level 1 Inputs — Quoted prices for identical instruments in active markets. Level 2 Inputs — Quoted prices for similar instruments in active markets; quoted prices for identical or similar instruments in markets that are not active; and model-derived valuations whose inputs are observable or whose significant value drivers are observable. Level 3 Inputs — Instruments with primarily unobservable value drivers. The following tables present our assets and liabilities that are measured at fair value on a recurring basis and are categorized using the fair value hierarchy. (In thousands) Quoted Prices Significant Significant Fair Value at Available-for-sale debt securities: U.S. Treasury and other government $ - $ 28,742 $ - $ 28,742 Corporate bonds - 144 - 144 Total available-for-sale debt securities - 28,886 - 28,886 Marketable equity securities: Stocks – foreign 1,606 - - 1,606 Stocks – domestic 9,403 - - 9,403 Mutual funds – foreign - 42,359 - 42,359 Mutual funds – domestic - 87,430 - 87,430 Total marketable equity securities 11,009 129,789 - 140,798 Contingent consideration - - ( 2,210 ) ( 2,210 ) Total $ 11,009 $ 158,675 $ ( 2,210 ) $ 167,474 (In thousands) Quoted Prices Assets Significant Significant Fair Value at Available-for-sale debt securities: U.S. Treasury and other government $ - $ 26,559 $ - $ 26,559 Corporate bonds - 138 - 138 Total available-for-sale debt securities - 26,697 - 26,697 Marketable equity securities: Stocks – foreign 1,518 - - 1,518 Stocks – domestic 9,028 - - 9,028 Mutual funds – foreign - 39,114 - 39,114 Mutual funds – domestic - 77,966 - 77,966 Total marketable equity securities 10,546 117,080 - 127,626 Contingent consideration - - ( 2,229 ) ( 2,229 ) Total $ 10,546 $ 143,777 $ ( 2,229 ) $ 152,094 Our investments in available-for-sale debt securities and marketable equity securities are valued using a market approach. The availability of inputs observable in the market varies from instrument to instrument and depends on a variety of factors, including the type of instrument, whether the instrument is actively traded and other characteristics particular to the transaction. For most of our financial instruments, pricing inputs are readily observable in the market, the valuation methodology used is widely accepted by market participants, and the valuation does not require significant management discretion. For other financial instruments, pricing inputs are less observable in the market and may require management judgment. The contingent consideration represents the estimated fair value of the additional variable cash consideration payable in connection with recent acquisitions that is contingent upon the achievement of certain performance milestones. We estimated the fair value using expected future cash flows over the period in which the obligation is expected to be settled which is considered to be a Level 3 input. In the Consolidated Statements of Cash Flows, payments of acquisition-related contingent consideration for the amount recognized at fair value as of the acquisition date are reported in cash flows from financing activities, while payments of contingent consideration in excess of fair value as of the acquisition date, are reported in cash flows from operating activities within other accrued liabilities. The carrying value of our current financial instruments, which include cash and cash equivalents, marketable securities, trade accounts receivable, accounts payable and short-term debt approximates fair value because of the short-term maturity of these financial instruments. At August 31, 2024 and May 31, 2024, the fair value of our long-term debt was estimated using active market quotes, based on our current incremental borrowing rates for similar types of borrowing arrangements, which are Level 2 inputs. Based on the analysis performed, the fair value and the carrying value of our long-term debt as of August 31, 2024 and May 31, 2024 is as follows: At August 31, 2024 (In thousands) Carrying Value Fair Value Long-term debt, including current portion $ 2,052,166 $ 1,958,791 At May 31, 2024 (In thousands) Carrying Value Fair Value Long-term debt, including current portion 2,127,148 1,979,359

Income Tax Disclosure [Abstract]
Income Taxes	NOTE 7 — INCOME TAXES The effective income tax rate of 21.3 % for the three months ended August 31, 2024 compares to the effective income tax rate of 25.2 % for the three months ended August 31, 2023. The effective income tax rates for both periods reflect variances from the 21 % statutory rate due to the unfavorable impact of state and local income taxes, non-deductible business expenses, and the net tax on foreign subsidiary income resulting from the global intangible low-taxed income provisions, partially offset by tax benefits related to equity compensation. Additionally, the effective income tax rate for the current three-month period ended August 31, 2024, reflects a favorable adjustment for incremental U.S. foreign tax credits associated with a distribution of historic foreign earnings that were previously not considered to be permanently reinvested. The distribution of such earnings was done in conjunction with global cash redeployment and debt optimization projects executed during the quarter. The effective income tax rate for the three-month period ended August 31, 2023 reflected incremental tax expense related to a change in the estimated net deferred tax liability for unremitted earnings and our liability for uncertain tax positions. Our deferred tax liability for unremitted foreign earnings was adjusted to $ 4.1 million as of May 31, 2024. The $ 4.1 million represented our estimate of the net tax cost of remitting of $ 285.6 million of foreign earnings that were not considered to be permanently reinvested. As of August 31, 2024, the amount of these earnings has changed to $ 164.0 million and we no longer have a tax liability associated with remitting these earnings. The reduction to the earnings amounts no longer permanently reinvested is due principally to distributions of such earnings during the quarter. We have not provided for foreign withholding or income taxes on the remaining foreign subsidiaries’ undistributed earnings because such earnings have been retained and reinvested by the subsidiaries as of August 31, 2024. Accordingly, no provision has been made for foreign withholding or income taxes, which may become payable if the remaining undistributed earnings of foreign subsidiaries were remitted to us as dividends. The Organization for Economic Co-operation and Development (“OECD”) has proposed a framework comprised of rules and models, collectively referred to as Pillar Two (“P2”), that are designed to ensure that certain multi-national enterprises pay a minimum tax rate of 15 % on reported profits arising in each jurisdiction where they operate. Although the OECD provided a framework for applying the minimum tax, individual countries have and may continue to enact P2 rules that are different than the OECD framework. While we continue to monitor P2 developments, we do not anticipate that P2 will have a material impact on our long-term financial position.

Equity [Abstract]
Stock Repurchase Program	NOTE 9 — STOCK REPURCHASE PROGRAM On January 8, 2008 , we announced our authorization of a stock repurchase program under which we may repurchase shares of RPM International Inc. common stock at management’s discretion. As announced on November 28, 2018, our goal was to return $ 1.0 billion in capital to stockholders by May 31, 2021 through share repurchases and the retirement of our convertible note during fiscal 2019. On April 16, 2019, after taking into account share repurchases under our existing stock repurchase program to date, our Board of Directors authorized the repurchase of the remaining $ 600.0 million in value of RPM International Inc. common stock by May 31, 2021. As previously announced, given macroeconomic uncertainty resulting from the Covid pandemic, we had suspended stock repurchases under the program, but in January 2021, our Board of Directors authorized the resumption of the stock repurchases. At the time of resuming the program, $ 469.7 million of shares of common stock remained available for repurchase. The Board of Directors also extended the stock repurchase program beyond its original May 31, 2021 expiration date until such time that the remaining $ 469.7 million of capital has been returned to our stockholders. As a result, we may repurchase shares from time to time in the open market or in private transactions at various times and in amounts and for prices that our management deems appropriate, subject to insider trading rules and other securities law restrictions. The timing of our purchases will depend upon prevailing market conditions, alternative uses of capital and other factors. We may limit or terminate the repurchase program at any time. During the three months ended August 31, 2024, we repurchased 152,146 shares of our common stock at a cost of approximately $ 17.5 million, or an average of $ 115.02 per share, under this program. During the three months ended August 31, 2023, we repurchased 122,425 shares of our common stock at a cost of $ 12.5 million, or an average of $ 102.10 per share, under this program. The maximum dollar amount that may yet be repurchased under our stock repurchase program was approximately $ 244.8 million at August 31, 2024.

We expect that pension expense will fluctuate on a year-to-year basis, depending upon the investment performance of plan assets and potential changes in interest rates, and these fluctuations may have a material impact on our consolidated financial results in the future. We are required and expect to contribute approximately $ 5.9 million to plans outside the U.S. during the current fiscal year and we will evaluate whether to make additional contributions to plans in the U.S. and outside the U.S. throughout fiscal 2025.

Contingencies and Accrued Losse

Contingencies and Accrued Losses	3 Months Ended

Commitments and Contingencies Disclosure [Abstract]
Contingencies and Accrued Losses	NOTE 13 — CONTINGENCIES AND ACCRUED LOSSES Product Liability Matters We provide, through our wholly-owned insurance subsidiaries, certain insurance coverage, primarily product liability coverage, to our other subsidiaries. Excess coverage is provided by third-party insurers. Our product liability accruals provide for these potential losses as well as other uninsured claims. Product liability accruals are established based upon actuarial calculations of potential liability using industry experience, actual historical experience and actuarial assumptions developed for similar types of product liability claims, including development factors and lag times. To the extent there is a reasonable possibility that potential losses could exceed the amounts already accrued, we believe that the amount of any such additional loss would be immaterial to our results of operations, liquidity and consolidated financial position. Warranty Matters We also offer warranties on many of our products, as well as long-term warranty programs at certain of our businesses, and have established product warranty liabilities. We review these liabilities for adequacy on a quarterly basis and adjust them as necessary. The primary factors that could affect these liabilities may include changes in performance rates as well as costs of replacement. Provision for estimated warranty costs is recorded at the time of sale and periodically adjusted, as required, to reflect actual experience. It is probable that we will incur future losses related to warranty claims we have received but that have not been fully investigated and related to claims not yet received. While our warranty liabilities represent our best estimates at August 31, 2024, we can provide no assurances that we will not experience material claims in the future or that we will not incur significant costs to resolve such claims beyond the amounts accrued or beyond what we may recover from our suppliers. Based upon the nature of the expense, product warranty expense is recorded as a component of cost of sales or within SG&A. Also, due to the nature of our businesses, the amount of claims paid can fluctuate from one period to the next. While our warranty liabilities represent our best estimates of our expected losses at any given time, from time-to-time we may revise our estimates based on our experience relating to factors such as weather conditions, specific circumstances surrounding product installations and other factors. The following table includes the changes in our accrued warranty balances: Three Months Ended August 31, August 31, (In thousands) 2024 2023 Beginning Balance $ 11,621 $ 11,776 Deductions (1) ( 6,143 ) ( 7,407 ) Provision charged to expense 5,712 7,633 Ending Balance $ 11,190 $ 12,002 (1) Primarily claims paid during the period. Environmental Matters Like other companies participating in similar lines of business, some of our subsidiaries are involved in environmental remediation matters. It is our policy to accrue remediation costs when the liability is probable and the costs are reasonably estimable, which generally is not later than at completion of a feasibility study or when we have committed to an appropriate plan of action. We also take into consideration the estimated period of time over which payments may be required. The liabilities are reviewed periodically and, as investigation and remediation activities continue, adjustments are made as necessary. Liabilities for losses from environmental remediation obligations do not consider the effects of inflation and anticipated expenditures are not discounted to their present value. The liabilities are not offset by possible recoveries from insurance carriers or other third parties but do reflect anticipated allocations among potentially responsible parties at federal superfund sites or similar state-managed sites, third-party indemnity obligations, and an assessment of the likelihood that such parties will fulfill their obligations at such sites. Other Contingencies One of our former subsidiaries in our SPG reportable segment has been the subject of a proceeding in which one of its former distributors brought suit against the subsidiary for breach of contract. Following a June 2017 trial, a jury determined that the distributor was not entitled to any damages on the distributor’s claims. On appeal, the Ninth Circuit Court of Appeals ordered a new trial with respect to certain issues. On December 10, 2021, a new jury awarded $ 6.0 million in damages to the distributor. Per the parties’ contracts, the distributor was also entitled to seek recovery of some portion of its attorneys’ fees and costs. On July 3, 2023, the Ninth Circuit Court of Appeals issued its decision rejecting the distributor's arguments and denying all appellate relief to the distributor, which also rendered our cross-appeal moot. On November 15, 2023, the U.S. District Court for the Eastern District of California issued an order awarding the distributor approximately $ 4.4 million in connection with attorney's fees and costs the distributor allegedly incurred throughout the duration of this legal action. As a result of this order, we increased our accrual to $ 10.4 million as of November 30, 2023. On December 27, 2023, we paid the $ 6.0 million judgment, and then decreased our accrual to approximately $ 4.4 million. However, because we strongly disagree with the District Court's order awarding attorneys’ fees and costs to the distributor, we timely filed an appeal of this order with the Ninth Circuit Court of Appeals, which remains pending. This contingency remains a liability of the Company. One of our subsidiaries in our Consumer reportable segment has been the subject of a lawsuit filed in the United States District Court for the District of Oregon in which a former supplier of that subsidiary alleged that the subsidiary breached certain contractual obligations, misappropriated trade secrets, and committed fraud in connection with an Exclusive Sales Agreement and a Mutual Settlement Agreement and Release executed in November 2015 and 2017, respectively. Our subsidiary denied, and continues to deny, these allegations. A jury trial commenced in this matter on September 17, 2024 . On September 27, 2024, the jury rendered a verdict against our subsidiary for $ 190.0 million, consisting of both compensatory and punitive damages. We believe that the jury verdict is not supported by the facts of the case or applicable law, is the result of significant trial error, and there are strong grounds for appeal. We intend to vigorously challenge the verdict through appropriate post-trial motions and appellate processes. As a result, we believe that the likelihood that the amount of the judgment will be affirmed is not probable. We currently estimate a range of possible outcomes between approximately $ 0.5 million and $ 190.0 million, and we have accrued a liability as of August 31, 2024, at the low end of the range, as no amount within the range is a better estimate than any other amount. This amount is reflected in accrued losses, and selling, general and administrative expenses in our consolidated financial statements as of and for the quarter ended August 31, 2024. The ultimate loss to the Company with respect to the litigation matter could be materially different from the amount the Company has accrued. The Company cannot predict or estimate the duration or ultimate outcome of this matter. Gain on Business Interruption Insurance In April 2021, there was a significant plant explosion at a key alkyd resin supplier which caused severe supply chain disruptions. As a result of this disruption, the Consumer segment incurred incremental costs and lost sales during fiscal 2021 and 2022. A claim for these losses was submitted under our business interruption insurance policy. The Consumer segment recovered $ 10.3 million from insurance during the first quarter of fiscal 2024, which was recorded as a gain in the three-month period ending August 31, 2023. No such proceeds were received during the three-month period ending August 31, 2024. The insurance gains are recorded as a reduction to SG&A expenses in our Consolidated Statements of Income, and the proceeds are included within cash flows from operating activities in our Consolidated Statement of Cash Flows.

Payables and Accruals [Abstract]
Supply Chain Financing	NOTE 14 — SUPPLY CHAIN FINANCING During the fourth quarter of 2024, we began offering a supplier finance program with a financial institution, in which suppliers may elect to receive early payment from the financial institution on invoices issued to RPM. The financial institution enters into separate arrangements with suppliers directly to participate in the program. We do not determine the terms or conditions of such arrangements or participate in the transactions between the suppliers and the financial institution. There are no assets pledged by RPM under the supplier finance program. Our responsibility is limited to making payments to the financial institution based on payment terms originally negotiated with the suppliers, regardless of whether the financial institution pays the supplier in advance of the original due date. The range of payment terms RPM negotiates with suppliers are consistent, regardless of whether a supplier participates in the supply chain finance program. RPM or the financial institution may terminate participation in the program upon at least 30 days ’ notice. The total amount due to the financial institution to settle supplier invoices under the supply chain finance program was $ 52.0 million and $ 32.9 million as of August 31, 2024 and May 31, 2024, respectively. These amounts are included within accounts payable on the Consolidated Balance Sheets.

Revenue

Revenue from Contract with Customer [Abstract]
Revenue	NOTE 15 — REVENUE We operate a portfolio of businesses that manufacture and sell a variety of product lines that include specialty paints, protective coatings, roofing systems, sealants and adhesives, among other things. We disaggregate revenues from the sales of our products and services based upon geographical location by each of our reportable segments, which are aligned by similar economic factors, trends and customers, which best depict the nature, amount, timing and uncertainty of revenue and cash flows arising from contracts with customers. See Note 16, “Segment Information,” to the Consolidated Financial Statements for further details regarding our disaggregated revenues, as well as a description of each of the unique revenue streams related to each of our four reportable segments. Revenue is recognized upon transfer of control of promised products or services to customers in an amount that reflects the consideration we expect to receive in exchange for those products or services. The majority of our revenue is recognized at a point in time. However, we also record revenues generated under construction contracts, mainly in connection with the installation of specialized roofing and flooring systems and related services. For certain polymer flooring installation projects, we account for our revenue using the output method, as we consider square footage of completed flooring to be the best measure of progress toward the complete satisfaction of the performance obligation. In contrast, for certain of our roofing installation projects, we account for our revenue using the input method, as that method is the best measure of performance as it considers costs incurred in relation to total expected project costs, which essentially represents the transfer of control for roofing systems to the customer. In general, for our construction contracts, we record contract revenues and related costs as our contracts progress on an over-time model. We have elected to apply the practical expedient to recognize revenue net of allowances for returns and any taxes collected from customers, which are subsequently remitted to governmental authorities. Payment terms and conditions vary by contract type, although our customers’ payment terms generally include a requirement to pay within 30 to 60 days of fulfilling our performance obligations . In instances where the timing of revenue recognition differs from the timing of invoicing, we have determined that our contracts generally do not include a significant financing component. We have elected to apply the practical expedient to treat all shipping and handling costs as fulfillment costs, as a significant portion of these costs are incurred prior to control transfer. Significant Judgments Our contracts with customers may include promises to transfer multiple products and/or services to a customer. Determining whether products and services are considered distinct performance obligations that should be accounted for separately versus together may require significant judgment. For example, judgment is required to determine whether products sold in connection with the sale of installation services are considered distinct and accounted for separately, or not distinct and accounted for together with installation services and recognized over time. We provide customer rebate programs and incentive offerings, including special pricing and co-operative advertising arrangements, promotions and other volume-based incentives. These customer programs and incentives are considered variable consideration and recognized as a reduction of net sales. Up-front consideration provided to customers is capitalized as a component of other assets and amortized over the estimated life of the contractual arrangement. We include in revenue variable consideration only to the extent that it is probable that a significant reversal in the amount of cumulative revenue recognized will not occur when the variable consideration is resolved. In general, this determination is made based upon known customer program and incentive offerings at the time of sale and expected sales volume forecasts as it relates to our volume-based incentives. This determination is updated each reporting period. Certain of our contracts include contingent consideration that is receivable only upon the final inspection and acceptance of a project. We include estimates of such variable consideration in our transaction price. Based on historical experience, we consider the probability-based expected value method appropriate to estimate the amount of such variable consideration. Our products are generally sold with a right of return, and we may provide other credits or incentives, which are accounted for as variable consideration when estimating the amount of revenue to recognize. Returns and credits are estimated at contract inception and updated at the end of each reporting period as additional information becomes available. We record a right of return liability to accrue for expected customer returns. Historical actual returns are used to estimate future returns as a percentage of current sales. Obligations for returns and refunds were not material individually or in the aggregate. We offer assurance type warranties on our products as well as separately sold warranty contracts. Revenue related to warranty contracts that are sold separately is recognized over the life of the warranty term. Warranty liabilities for our assurance type warranties are discussed further in Note 13, “Contingencies and Accrued Losses,” to the Consolidated Financial Statements. Contract Balances Timing of revenue recognition may differ from the timing of invoicing customers. Our contract assets are recorded for products and services that have been provided to our customer but have not yet been billed and are included in prepaid expenses and other current assets in our Consolidated Balance Sheets. Our short-term contract liabilities consist of advance payments, or deferred revenue, and are included in other accrued liabilities in our Consolidated Balance Sheets. Trade accounts receivable, net of allowances, and net contract assets consisted of the following: (In thousands, except percentages) August 31, 2024 May 31, 2024 $ Change % Change Trade accounts receivable, less allowances $ 1,344,177 $ 1,419,445 $ ( 75,268 ) ( 5.3 %) Contract assets $ 78,537 $ 57,833 $ 20,704 35.8 % Contract liabilities - short-term ( 52,480 ) ( 44,996 ) ( 7,484 ) 16.6 % Net Contract Assets $ 26,057 $ 12,837 $ 13,220 The $ 13.2 million increase in our net contract assets from May 31, 2024 to August 31, 2024, resulted primarily due to the timing of construction jobs in progress at August 31, 2024 versus May 31, 2024. During the three-month periods ending August 31, 2024 and 2023, we recognized $ 22.6 million and $ 21.3 million of revenue, which is included in contract liabilities as of May 31, 2024 and 2023, respectively. We also record long-term deferred revenue, which amounted to $ 81.5 million and $ 81.7 million as of August 31, 2024 and May 31, 2024, respectively. The long-term portion of deferred revenue is related to warranty contracts and is included in other long-term liabilities in our Consolidated Balance Sheets. We have elected to adopt the practical expedient to not disclose the aggregate amount of transaction price allocated to performance obligations that are unsatisfied as of the end of the reporting period for performance obligations that are part of a contract with an original expected duration of one year or less. We recognize an asset for the incremental costs of obtaining a contract with a customer if we expect the benefit of those costs to be longer than one year. As our contract terms are primarily one year or less in duration, we have elected to apply a practical expedient to expense costs as incurred for costs to obtain a contract with a customer when the amortization period would have been one year or less. These costs include our internal sales force compensation program and certain incentive programs as we have determined annual compensation is commensurate with annual sales activities. Allowance for Credit Losses Our primary allowance for credit losses is the allowance for doubtful accounts. The allowance for doubtful accounts reduces the trade accounts receivable balance to the estimated net realizable value equal to the amount that is expected to be collected. The allowance was based on assessments of current creditworthiness of customers, historical collection experience, the aging of receivables and other currently available evidence. Trade accounts receivable balances are written-off against the allowance if a final determination of uncollectibility is made. All provisions for allowances for doubtful collection of accounts are included in SG&A expenses. The following tables summarize the activity for the allowance for credit losses for the three months ended August 31, 2024 and 2023: Three Months Ended August 31, August 31, (In thousands) 2024 2023 Beginning Balance $ 48,763 $ 49,482 Bad debt provision 947 7,696 Uncollectible accounts written off, net of recoveries ( 786 ) ( 782 ) Translation adjustments 182 188 Ending Balance $ 49,106 $ 56,584

Segment Reporting [Abstract]
Segment Information	NOTE 16 — SEGMENT INFORMATION We operate a portfolio of businesses and product lines that manufacture and sell a variety of specialty paints, protective coatings, roofing systems, flooring solutions, sealants, cleaners and adhesives. We manage our portfolio by organizing our businesses and product lines into four reportable segments as outlined below, which also represent our operating segments. Within each operating segment, we manage product lines and businesses which generally address common markets, share similar economic characteristics, utilize similar technologies and can share manufacturing or distribution capabilities. Our four operating segments represent components of our business for which separate financial information is available that is utilized on a regular basis by our chief operating decision maker in determining how to allocate the assets of the company and evaluate performance. These four operating segments are each managed by an operating segment manager, who is responsible for the day-to-day operating decisions and performance evaluation of the operating segment’s underlying businesses. We evaluate the profit performance of our segments primarily based on income before income taxes, but also look to earnings (loss) before interest and taxes (“EBIT”), as a performance evaluation measure because interest (income) expense, net is essentially related to corporate functions, as opposed to segment operations. Our CPG reportable segment products and services are sold throughout North America and also account for a significant portion of our international sales. Our construction product lines are sold directly to manufacturers, contractors, distributors and end-users, including industrial manufacturing facilities, concrete and cement producers, public institutions and other commercial customers. Products and services within this reportable segment include construction sealants and adhesives, coatings and chemicals, roofing systems, concrete admixture and repair products, building envelope solutions, parking decks, insulated cladding, firestopping, flooring systems, and weatherproofing solutions. Our PCG reportable segment products and services are sold throughout North America, as well as internationally, and are sold directly to contractors, distributors and end-users, such as industrial manufacturing facilities, public institutions and other commercial customers. Products and services within this reportable segment include high-performance flooring solutions, corrosion control and fireproofing coatings, infrastructure repair systems and FRP structures. Our Consumer reportable segment manufactures and markets professional use and DIY products for a variety of mainly residential applications, including home improvement and personal leisure activities. Our Consumer reportable segment’s major manufacturing and distribution operations are located primarily in North America, along with a few locations in Europe, Australia and South America. Our Consumer reportable segment products are primarily sold directly to mass merchandisers, home improvement centers, hardware stores, paint stores, craft shops and through distributors. The Consumer reportable segment offers products that include specialty, hobby and professional paints; caulks; adhesives; cleaners; sandpaper and other abrasives; silicone sealants and wood stains. Our SPG reportable segment products are sold throughout North America and internationally, primarily in Europe. Our SPG product lines are sold directly to contractors, distributors and end-users, such as industrial manufacturing facilities, public institutions and other commercial customers. The SPG reportable segment offers products that include restoration services equipment, colorants, nail enamels, factory applied industrial coatings, preservation products, and edible coatings and specialty glazes for pharmaceutical and food industries. In addition to our four reportable segments, there is a category of certain business activities and expenses, referred to as corporate/other, that does not constitute an operating segment. This category includes our corporate headquarters and related administrative expenses, results of our captive insurance companies, gains or losses on the sales of certain assets and other expenses not directly associated with any reportable segment. Assets related to the corporate/other category consist primarily of investments, prepaid expenses and headquarters’ property and equipment. These corporate and other assets and expenses reconcile reportable segment data to total consolidated income before income taxes and identifiable assets. We reflect income from our joint ventures on the equity method and receive royalties from our licensees. The following tables present a disaggregation of revenues by geography, and the results of our reportable segments consistent with our management philosophy, by representing the information we utilize, in conjunction with various strategic, operational and other financial performance criteria, in evaluating the performance of our portfolio of businesses.

Accounting Changes and Error Corrections [Abstract]
Consolidation, Noncontrolling Interests and Basis of Presentation	CONSOLIDATION, NONCONTROLLING INTERESTS AND BASIS OF PRESENTATION The accompanying unaudited Consolidated Financial Statements have been prepared in accordance with Generally Accepted Accounting Principles in the U.S. (“GAAP”) for interim financial information and the instructions to Form 10-Q. In our opinion, all adjustments (consisting of normal, recurring accruals) considered necessary for a fair presentation have been included for the three-month periods ended August 31, 2024 and 2023. For further information, refer to the Consolidated Financial Statements and Notes included in our Annual Report on Form 10-K for the year ended May 31, 2024. Our financial statements include all of our majority-owned subsidiaries. We account for our investments in less-than-majority-owned joint ventures, for which we have the ability to exercise significant influence, under the equity method. Effects of transactions between related companies are eliminated in consolidation. Noncontrolling interests are presented in our Consolidated Financial Statements as if parent company investors (controlling interests) and other minority investors (noncontrolling interests) in partially-owned subsidiaries have similar economic interests in a single entity. As a result, investments in noncontrolling interests are reported as equity in our Consolidated Financial Statements. Additionally, our Consolidated Financial Statements include 100 % of a controlled subsidiary’s earnings, rather than only our share. Transactions between the parent company and noncontrolling interests are reported in equity as transactions between stockholders, provided that these transactions do not create a change in control. Our business is dependent on external weather factors. Historically, we have experienced strong sales and net income in our first, second and fourth fiscal quarters comprising the three-month periods ending August 31, November 30, and May 31, respectively, with weaker performance in our third fiscal quarter (December through February).
New Pronouncements Adopted and Issued	NEW ACCOUNTING PRONOUNCEMENTS New Pronouncements Adopted In September 2022, the Financial Accounting Standards Board ("FASB") issued Accounting Standard Update ("ASU") 2022-04, "Liabilities - Supplier Finance Programs (Subtopic 405-50)," which is intended to establish disclosures that enhance the transparency of a supplier finance program used by an entity in connection with the purchase of goods and services. This guidance requires annual and interim disclosure of the key terms of outstanding supplier finance programs, the amount outstanding under such programs including where they are recorded on the balance sheet, and a roll-forward of the related obligations. The new standard does not affect the recognition, measurement, or financial statement presentation of the supplier finance program obligations. These amendments are effective for fiscal years beginning after December 15, 2022, except for the amendment on roll-forward information, which is effective for fiscal years beginning after December 15, 2023. We adopted the new standard on June 1, 2023 , on a retrospective basis other than the roll-forward guidance, which we plan to adopt on a prospective basis beginning with our fiscal 2025 annual financial statements. As of adoption on June 1, 2023, we did no t have any material supplier finance program obligations; however, we began such an arrangement during the fourth quarter of fiscal 2024. Refer to Note 14, “Supply Chain Financing,” to the Consolidated Financial Statements. New Pronouncements Issued In December 2023, the FASB issued ASU 2023-09, "Income Taxes (Topic 740): Improvements to Income Tax Disclosures," which requires a public business entity to disclose specific categories in its annual effective tax rate reconciliation and disaggregated information about significant reconciling items by jurisdiction and by nature. The ASU also requires entities to disclose their income tax payments (net of refunds) to international, federal, and state and local jurisdictions. The guidance makes several other changes to income tax disclosure requirements. This guidance is effective for fiscal years beginning after December 15, 2024, and requires prospective application with the option to apply it retrospectively. Early adoption is permitted. We are currently evaluating this ASU to determine its impact on our disclosures. In November 2023, the FASB issued ASU 2023-07, "Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures," which expands disclosures about a public business entity's reportable segments and provides for more detailed information about a reportable segment's expenses. This guidance is effective for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024, and requires retrospective application to all prior periods presented in the financial statements. Early adoption is permitted. We are currently evaluating this ASU to determine its impact on our disclosures.
