Exhibit 99.1 RPM Reports Record Fiscal 2026 First-Quarter Results • Record first-quarter sales of $2.11 billion, an increase of 7.4% compared to the prior year • First-quarter net income of $227.6 million, diluted EPS of $1.77, and record EBIT of $314.0 million • Record first-quarter adjusted diluted EPS of $1.88, an increase of 2.2% over the prior-year record; record adjusted EBIT of $337.8 million, an increase of 2.9% over the prior-year record • Fiscal 2026 second-quarter outlook calls for mid-single-digit sales and adjusted EBIT growth • Fiscal 2026 full-year outlook calls for sales to increase toward the higher end of the previously announced low-to mid-single-digit range and adjusted EBIT to increase toward the lower end of the previously announced high-single- to low-double-digit range MEDINA, OH – October 1, 2025 – RPM International Inc. (NYSE: RPM), a world leader in specialty coatings, sealants and building materials, today reported record financial results for its fiscal 2026 first quarter ended August 31, 2025. Frank C. Sullivan, RPM chairman and CEO commented, “Our associates’ focused pivot to growth was evident during the quarter with organic sales up solidly in a challenging macro environment. We leveraged our ability to provide turnkey solutions and systems to high-performance buildings and benefited from our focus on repair and maintenance. The successful integration of strategic business acquisitions also played an important role in achieving record sales. Adjusted EBIT was a record as the strong top-line growth and MAP 2025 operational improvement benefits more than offset the impact of SG&A growth investments, higher healthcare expenses and increased inflation. I am proud of our ability to generate record adjusted EBIT in 14 out of the last 15 quarters.” RPM Reports Results for Fiscal 2026 1st Quarter October 1, 2025 Page 2 First-Quarter 2026 Consolidated Results Consolidated Three Months Ended $in 000s except per share data August 31, August 31, 2025 2024 $ Change % Change Net Sales $ 2,113,743 $ 1,968,789 $ 144,954 7.4 % Net Income Attributable to RPM Stockholders 227,605 227,692 (87 ) (0.0 %) Diluted Earnings Per Share (EPS) 1.77 1.77 — 0.0 % Income Before Income Taxes (IBT) 298,047 290,451 7,596 2.6 % Earnings Before Interest and Taxes (EBIT) 313,969 303,859 10,110 3.3 % Adjusted EBIT (1) 337,792 328,342 9,450 2.9 % Adjusted Diluted EPS (1) 1.88 1.84 0.04 2.2 % (1) Excludes certain items that are not indicative of RPM’s ongoing operations. See tables below titled Supplemental Segment Information and Reconciliation of Reported to Adjusted Amounts for details. Record first-quarter sales were driven by systems and turnkey solutions to serve high-performance buildings as well as a focus on repair and maintenance. Acquisitions also played a meaningful role in generating the record results. Geographically, Europe led sales growth with an increase of 20.7%, driven by acquisitions and favorable foreign exchange. North America sales increased 5.9%, driven by demand for systems and turnkey solutions. Sales were mixed in emerging markets, with Africa / Middle East leading growth, driven by infrastructure and high-performance building projects. Sales included 3.0% organic growth, 3.8% growth from acquisitions, and a 0.6% benefit from foreign currency translation. Adjusted EBIT was a record, driven by sales and volume growth, which leveraged MAP 2025 operational improvements, and the successful integration of acquired businesses. This was partially offset by cost inflation and higher SG&A, which included an increase in healthcare and M&A expenses. Growth investments also contributed to higher SG&A. Adjusted diluted EPS was a record and was driven by the improvement in adjusted EBIT, partially offset by higher interest expense resulting from debt being used to finance acquisitions.

See table below titled Supplemental Segment Information for details. Record CPG sales were driven by systems and turnkey roofing solutions serving high-performance buildings and infrastructure projects, partially offset by soft market conditions in Europe and in the disaster restoration business due to reduced storm activity compared to the prior year. Sales included 5.4% organic growth, 0.5% growth from acquisitions, and a 0.6% benefit from foreign currency translation. Adjusted EBIT was a record, and the increase was driven by higher sales and MAP 2025 benefits, partially offset by SG&A growth investments and temporary inefficiencies from plant consolidations as production was being transferred. This adjusted EBIT growth was in addition to strong growth in the prior-year.

See table below titled Supplemental Segment Information for details. Record PCG sales were driven by broad-based strength including turnkey flooring solutions serving high-performance buildings, protective coatings and specialty OEM coatings. Acquisitions also contributed to the sales increase. Sales included 6.7% organic growth, a 2.5% increase from acquisitions, and a 0.7% benefit from foreign currency translation. Adjusted EBIT increased to a record, driven by higher sales and MAP 2025 operational improvement initiatives, partially offset by growth investments and unfavorable mix.

See table below titled Supplemental Segment Information for details. The Consumer Group’s record sales were driven by the successful integration of acquisitions, partially offset by softness in DIY markets and product rationalization. Sales included a 2.9% organic decline, 9.1% growth from acquisitions, and a 0.4% benefit from foreign currency translation. Adjusted EBIT growth was driven by acquired businesses with accretive margins and MAP 2025 benefits, which were partially offset by cost inflation, reduced fixed-cost utilization from lower volumes, temporary inefficiencies from plant consolidations and increased marketing expenses. Cash Flow and Financial Position During the first three months of fiscal 2026: • Cash provided by operating activities was $237.5 million, driven by profitability growth and efficient working capital enabled by MAP 2025 initiatives, partially offset by strategic inventory purchases to mitigate the future impact of tariffs and to ensure high service levels during the consolidation of 6 manufacturing facilities. • Capital expenditures were $62.5 million compared to $50.7 million during fiscal year 2025 with the increase driven by growth investments, including the purchase of RPM’s recently constructed Malaysian plant. • The company returned $82.0 million to stockholders through cash dividends and share repurchases, an increase of 7.4% compared to the prior year. As of August 31, 2025: • Total debt was $2.67 billion compared to $2.05 billion a year ago, with the $617.3 million increase driven by debt used to finance acquisitions. • Total liquidity, including cash and committed revolving credit facilities, was $933.4 million, compared to $1.44 billion a year ago, with the decrease driven by the use of the credit facilities to finance acquisitions. RPM Reports Results for Fiscal 2026 1st Quarter October 1, 2025 Page 5 Business Outlook Sullivan said, “Our pivot to growth will continue in the second quarter as we leverage our competitive strengths in non-residential construction markets and benefit from growth investments in several of our businesses. While tariff-related inflation remains a challenge, we are working to mitigate these headwinds through a series of measures, including price increases late in the first quarter. We will also begin realizing more efficiency benefits from our streamlined three-segment structure in the second quarter.” He concluded, “For the full year, we are increasing our growth investments in areas with the highest potential. While these investments will increase SG&A, we anticipate they will help accelerate our growth in what remains a challenging macro environment. Taking all of this into account, we expect to achieve record sales and adjusted EBIT in both the second quarter and for the full fiscal year.” The company expects the following in the fiscal 2026 second quarter: • Consolidated sales to increase in the mid-single-digit percentage range compared to prior-year results. • Consumer sales growth to be moderately higher than the other two segments due to acquisitions. • Consolidated adjusted EBIT to be up in the mid-single-digit percentage range compared to prior-year record results. The company expects the following in full-year fiscal 2026: • Consolidated sales to increase toward the higher end of the previous outlook of low-single- to mid-single-digit growth compared to prior-year record results. • Consolidated adjusted EBIT to increase toward the lower end of the previous outlook of high-single- to low-double-digit percentage growth compared to prior-year record results.

EBIT is defined as earnings (loss) before interest and taxes, with adjusted EBIT and adjusted earnings per share provided for the purpose of adjusting for one-off items impacting revenues and/or expenses that are not considered by management to be indicative of ongoing operations. We evaluate the profit performance of our segments based on income before income taxes, but also look to EBIT as a performance evaluation measure because interest income (expense), net is essentially related to corporate functions, as opposed to segment operations. For that reason, we believe EBIT is also useful to investors as a metric in their investment decisions. EBIT should not be considered an alternative to, or more meaningful than, income before income taxes as determined in accordance with GAAP, since EBIT omits the impact of interest and investment income or expense in determining operating performance, which represent items necessary to our continued operations, given our level of indebtedness. Nonetheless, EBIT is a key measure expected by and useful to our fixed income investors, rating agencies and the banking community all of whom believe, and we concur, that this measure is critical to the capital markets’ analysis of our segments’ core operating performance. We also evaluate EBIT because it is clear that movements in EBIT impact our ability to attract financing. Our underwriters and bankers consistently require inclusion of this measure in offering memoranda in conjunction with any debt underwriting or bank financing. EBIT may not be indicative of our historical operating results, nor is it meant to be predictive of potential future results. See the financial statement section of this earnings release for a reconciliation of EBIT and adjusted EBIT to income before income taxes, and adjusted earnings per share to earnings per share. We have not provided a reconciliation of our second-quarter fiscal 2026 or full-year fiscal 2026 adjusted EBIT guidance because material terms that impact such measure are not in our control and/or cannot be reasonably predicted, and therefore a reconciliation of such measure is not available without unreasonable effort.
