Competition

We conduct our business in highly competitive markets, and all of our major products face competition from local, regional, national and multi-national firms. Our markets, however, are fragmented, and we do not face competition across all of our products from any one competitor in particular. Several of our competitors have access to greater financial resources and larger sales organizations than we do. While third-party figures are not necessarily available with respect to the size of our position in the market for each of our products, we believe that we are a major producer of caulks, sealants, insulating foams, patch-and-repair products for the general consumer as well as for the residential building trade; roofing systems; urethane sealants and waterproofing materials; aluminum coatings; cement-based coatings; hobby paints; small project paints; industrial-corrosion-control products; fireproofing; consumer rust-preventative coatings; polymer floorings; fluorescent coatings and pigments; fiberglass-reinforced-plastic gratings; nail polish; water and fire damage restoration products; carpet cleaning truck-mount systems and shellac-based coatings. However, we do not believe that we have a significant share of the total protective coatings market (on a world-wide basis). The following is a summary of the competition that our key products face in the various markets in which we compete:

Paints, Coatings, Adhesives and Sealants Products

The market for paints, coatings, adhesives and sealants has experienced significant consolidation over the past several decades. However, the market remains fragmented, which creates further consolidation opportunities for industry participants. Many leading suppliers tend to focus on coatings, while other companies focus on adhesives and sealants. Barriers to market entry are relatively high for new market

6

entrants due to the lengthy intervals between product development and market acceptance, the importance of brand identity and the difficulty in establishing a reputation as a reliable supplier of these products. Most of the suppliers, including us, who provide these items have a portfolio of products that span across a wide variety of applications.

Consumer Home Improvement Products. Within our Consumer reportable segment, we generally serve the home improvement market with products designed for niche architectural, rust-preventative, decorative and special purpose paint and caulking and sealing applications. The products we sell for home improvement include those sold under our Rust-Oleum, Varathane, Watco, Zinsser, DAP, and Touch’N Foam brand names. Leading manufacturers of home improvement-related coatings, adhesives and sealants market their products to DIY users and contractors through a wide range of distribution channels. These distribution channels include direct sales to home improvement centers, mass merchandisers, hardware and paint stores, and sales through distributors and sales representative organizations. Competitors in this market generally compete for market share by marketing and building upon brand recognition, providing customer service and developing new products based on customer needs.

Industrial Protective Coatings Products. Anti-corrosion protective coatings and fireproofing must withstand the destructive elements of nature and operating processes under harsh environments and conditions. Our protective industrial coating products are marketed primarily under our Carboline, Specialty Polymer Coatings, Plasite, Nullifire, Firefilm, Charflame, A/D Fire, Strathmore, Thermo-lag, Perlifoc, Epoplex, and Farbocustic brand names. Some of the larger consumers of high-performance protective and corrosion control coatings, fireproofing and intumescent steel coatings are the oil and gas, pulp and paper, petrochemical, shipbuilding, high-rise building construction, public utility and bridge and highway industries, water and wastewater treatment plants, and electronics manufacturing facilities. These markets are highly fragmented. We and our competitors compete for market share by supplying a wide variety of high-quality products and by offering customized solutions.

Roofing Systems Products

In the roofing industry, re-roofing applications have historically accounted for over three-quarters of U.S. demand, with the remainder generated by new roofing applications. Our primary roofing brand, Tremco, was founded in 1928 on the principle of “keeping good roofs good,” and then, by extension, ensuring “roofing peace of mind” for our customers. We define the market in two segments: (a) restoration and re-roofing or (b) new roofing. We market our systems and services for all of the most common roofing applications. Our roofing systems and services provide high performance and value. High performance ensures a long service life and ease of maintenance. High value ensures low total cost of ownership due to ease of installation, landfill avoidance, roof longevity, elimination of facility and occupant disruption, and utilization of sustainable materials and systems. Whether a project is a restoration, re-roof or new construction, our goal is always to help create a facility that is safe, dry, comfortable, and energy efficient for its occupants.

Construction Products

Flooring Systems Products. Polymer flooring systems are used in industrial, commercial and, to a lesser extent, residential applications to provide a smooth, seamless surface that is impervious to penetration by water and other substances while being easy to clean and maintain. These systems are particularly well-suited for clean environments such as pharmaceutical, food and beverage and healthcare facilities. In addition, the fast installation time and long-term durability of these systems and products make them ideal for industrial floor repair and restoration. Polymer flooring systems are based on epoxy, polyurethane and methyl methacrylate resins. Most of these flooring systems are applied during new construction, but there is also a significant repair and renovation market. Key performance attributes in polymer flooring systems that distinguish competitors for these applications include static control, chemical resistance, contamination control, durability and aesthetics. We market our flooring systems under the Stonhard, Flowcrete, Key Resin, Euclid, Liquid Elements, Hummervoll, Kemtile, API and Dudick brand names.

Fiberglass Reinforced Plastic (“FRP”) Grating and Structural Composites. FRP grating and railings are used primarily in industrial and, to a lesser extent, commercial applications. FRP exhibits many specialized features, which make it a beneficial alternative to traditional steel or aluminum. These include a high strength-to-weight ratio, high corrosion resistance, electrical and thermal non-conductivity, and molded-in color, which eliminates the need for repainting. FRP is used for rooftop safety, platforms, walkways and stairs for a variety of applications, including those in the food and beverage, chemical processing, water-wastewater, pulp and paper, commercial roofing, commercial sealants and waterproofing, and offshore oil and gas industries. Structural composites include high-density polypropylene pedestal systems for raised flooring applications in outdoor environments. Key attributes that differentiate competitors in these markets include product quality, depth of product line, and design-and-fabrication services. Our products for these applications are sold under our Fibergrate, Chemgrate, Corgrate, Fibregrid, Safe-T-Span and Bison brand names.

Sealants, Waterproofing, Concrete and Masonry Products. Sealants, which include urethane, silicone, latex, butyl and hybrid technology products, are designed to be installed in construction joints for the purpose of providing a flexible air and water-tight seal. Waterproof coatings, usually urethane or asphalt based, are installed in exposed and buried applications to waterproof and protect concrete. Structural and traffic tolerant membranes, expansion joints and bearings are used in a variety of applications for bridge deck construction and restoration and the protection and preservation of balconies, pedestrian walkways and parking structures. In the concrete and masonry additives market, a variety of chemicals and fibers can be added to concrete and masonry to improve the processability, performance, or appearance of these products. Chemical admixtures for concrete are typically grouped according to their functional characteristics, such as water-reducers, set controllers, superplasticizers and air-entraining agents. Curing and sealing

7

compounds, structural grouts, epoxy adhesives, injection resins, floor hardeners and toppings, joint fillers, industrial and architectural coatings, decorative color/stains/stamps, and a comprehensive selection of restoration materials are used to protect, repair or improve new or existing concrete structures used in the construction industry, and rehabilitation and repair of roads, highways, bridges, pipes and other infrastructure. The key attributes that differentiate competitors for these applications include quality assurance, on-the-job consultation and value-added, highly engineered products. We primarily offer products marketed under our Tremco, EUCO, Toxement, Viapol, Betumat, CAVE, Vandex, illbruck, Tamms, AlphaGuard, AlphaGrade, OneSeal, PowerPly, TremPly, TremLock, Vulkem, TREMproof, Dymonic, Increte, TUFF-N-DRI, Universal Sealants, Nufins, Pitchmastic PMB, Visul, Fibrecrete, Texacrete, Fibrejoint, Samiscreed, Prime Rez, Prime Gel, Prime Guard, Prime Coat, Prime Bond, Prime Flex, Logiball, Watchdog Waterproofing, PSI, Tuf-Strand, Ekspan, Sealtite and HydroStop brand names for this line of business.

Building Wall, Cladding and Envelope Systems. CPG's collective products and systems are a single source for new construction, renovation and restoration. We take a fully tested systems approach in standing behind its whole building warranty, providing a single point of responsibility for customer peace of mind.

Intellectual Property

Our intellectual property portfolios include valuable patents, trade secrets and know-how, domain names, trademarks, trade and brand names. In addition, through our subsidiaries, we continue to conduct significant research and technology development activities. Among our most significant intangibles are our Rust-Oleum®, Carboline®, DAP®, illbruck® and Tremco® trademarks.

Our other principal product trademarks include: 2X Ultra Cover®, AlphaGuard®, Alumanation®, Betumat™, B-I-N®, Bitumastic®, Bulls Eye 1-2-3®, Chemgrate®, Dri-Eaz®, Dymonic®, EnerEDGE®, Enviro-Dri®, EUCO®, ExoAir®, Flecto™, Fibergrate®, Floquil™, Paraseal®, PermaroofTM, Plasite®, Proglaze®, Sanitile®, Sealtite™, Solargard®, Spectrem®, Stonblend®, Stonclad®, Stonhard®, Stonlux®, Stonshield®, Testors®, TREMproof®, TUFF-N-DRI®, Varathane®, Viapol™, Vulkem®, Watchdog Waterproofing®, Woolsey®, Zinsser® and Z-Spar®; and, in Europe, API®, Perlifoc®, Hummervoll®, USL®, Nufins®, Pitchmastic PMB®, Visul®, Flowcrete®, Nullifire®, Radglo® and Martin Mathys™. Our trademark registrations are valid for a variety of different terms of up to 15 years, and may be renewable as long as the trademarks continue to be used and all other local conditions for renewal are met. Our trademark registrations are maintained and renewed on a regular basis as required.

Raw Materials

The cost and availability of raw materials, including packaging, materially impact our financial results. We obtain raw materials from a number of suppliers. Many of our raw materials are petroleum-based derivatives, minerals and metals. The cost of raw materials has in the past experienced, and likely will continue to experience, periods of volatility which could increase the cost of manufacturing our products. Under normal market conditions, these materials are generally available on the open market from a variety of producers; however, shortages have occurred and continue to be a possibility. Interruptions in the supply of raw materials could have a significant impact on our ability to produce products.

Throughout fiscal 2023, we experienced inflation in raw materials. While costs of some raw materials have stabilized, we expect that inflation of some materials will potentially create headwinds impacting our results into fiscal 2024.

Additionally, changes in international trade duties and other aspects of international trade policy, both in the United States and abroad, could materially impact the cost and availability of raw materials. Any increase in material costs that are not offset by an increase in our prices could have an adverse effect on our business, financial position, results of operations or cash flows.

Seasonal Factors

Our business is dependent, to a significant extent, on external weather factors. We historically experience stronger sales and operating results in our first, second and fourth fiscal quarters, which are the three-month periods ending August 31, November 30 and May 31, respectively, while we have experienced weaker performance in our third fiscal quarter.

Customers

Sales to our ten largest Consumer segment customers, such as DIY home centers, on a combined basis represented approximately 25%, 22%, and 24% of our total net sales for each of the fiscal years ended May 31, 2023, 2022 and 2021, respectively. Except for sales to these customers, our business is not dependent upon any one customer or small group of customers but is largely dispersed over a substantial number of customers.

Research and Development

Our research and development work is performed at various laboratory locations. During fiscal years 2023, 2022 and 2021, approximately $86.6 million, $80.5 million and $77.6 million, respectively, was charged to expense for research and development activities. In addition to this laboratory work, we view our field technical service as being integral to the success of our research activities. Our research and development activities and our field technical service costs are both included as part of our selling, general and administrative expenses.

Environmental Matters

We value and respect our place in the world as a steward of the built environment and aspire to make the world a better place for our customers, associates, shareholders and the communities in which we live and operate through compliance with the environmental laws and regulations as well as fostering our own internal initiatives related to the environment and our social impact. In 2022 we launched our Building a Better World program. This program focuses on three pillars: Our People, Our Products and Our Processes.

We also established our Building a Better World Oversight Committee, overseen by our Governance and Nominating Committee of our Board of Directors, which is responsible for the direction of our sustainability efforts. The Building a Better World Oversight Committee has three additional subcommittees, each focused on one of the pillars of the Building a Better World program and reporting up to the Building a Better World Oversight Committee. At the management level, day-to-day implementation of our environmental, social and governance (“ESG”) initiatives is led by our Vice President – Compliance and Sustainability, Associate General Counsel.

We are subject to a broad range of laws and regulations dealing with environmental, health and safety issues for the various locations around the world in which we conduct our business. These laws and regulations include, but are not limited to, the following major areas:

•the sale, export, generation, storage, handling, use and transportation of hazardous materials;

•regulations related to greenhouse gas emissions, energy or climate change;

•the emission and discharge of hazardous materials into the soil, water and air; and

•the health and safety of our associates.

For information regarding environmental accruals, see Note P, “Contingencies and Accrued Losses,” to the Consolidated Financial Statements. For more information concerning certain environmental matters affecting us, see “Item 3 — Legal Proceedings — Environmental Proceedings” in this Annual Report on Form 10-K.

Human Capital

We understand that our company is only as strong as the team behind it. With the consistent support and dedication of leadership at all levels, we foster a workplace that supports our associates as individuals and helps them thrive in their current positions and strive to accomplish their future aspirations. Our human capital management strategy includes sustainable best practices in professional development, benefits, health and safety, and community involvement in an effort to continue to hire the best associates and retain them throughout the course of their careers. We measure satisfaction through our annual Engagement Survey, through which participants are able to express their opinion and provide comments and suggestions.

Talent Development

It is critical to our long-term success to develop our internal talent. Our Global Organizational Leadership Development (“GOLD”) Team is charged with creating a leadership-led learning culture across RPM. The GOLD Team has developed several training programs to support development which include Leaders of the Future, RPM University, Strategic Leader Staff Rides, and partnering with the Center for Creative Leadership. Since the inception of these programs the Company has seen many participants advance their careers, and the retention of participants has been greater than 85%.

Benefits

Our leadership has long understood that to attract and retain top talent, and to share the benefits of a successful business, we must maintain a premium benefits program for our associates. For U.S. associates, we offer an attractive benefits package, including defined benefit pension plans, medical, telehealth, tuition reimbursement and an employer-matched 401(k). We also offer an Employee Assistance Program (“EAP”) which focuses on behavioral health and also provides resources for financial and legal matters. Mental health support is key to associates, who may get support through the EAP as well as through telehealth and our health plans.

9

Similar ancillary benefits are offered to our Canadian associates, and associates of our other foreign subsidiaries receive benefits coverage, to the extent deemed appropriate, through plans that meet local requirements.

Diversity & Inclusion

At RPM, we are committed to fostering, cultivating and preserving a culture of diversity and inclusion. We support this commitment and provide associate resources through Respect at RPM, a program that reinforces our core values of operating with transparency, trust and respect. The program emphasizes the importance of diversity and inclusion at RPM and across all our operations; and supports associate growth and development. We have built our workforce with a commitment to create a diverse and inclusive culture. We recruit, select, hire and develop individuals based on their qualifications and skills. All associates and other parties involved in the employment relationship are required to comply with RPM’s Code of Conduct and are prohibited from discriminating against individuals during all stages of employment or hiring, including decisions involving recruitment, promotion, transfer, assignment, training, termination and lay-offs, working conditions, wage and salary administration, associate benefits and application of policies. We prohibit any inappropriate conduct or behavior against others, including discrimination perpetrated by associates, supervisors, customers or vendors, and strictly prohibit retaliation and harassment, as set forth in our Code of Conduct and Hotline and Non-Retaliation Policy.

Health & Safety

We follow many best practices to ensure our associates come to work feeling empowered to safely do their jobs. As part of our EH&S management system, we continuously educate and train to institutionalize our health and safety values, set and monitor health and safety objectives, conduct regular risk assessments and process hazard and root cause analysis, and actively enforce incident prevention and reporting policies. In addition, we conduct EH&S compliance audits annually that are prioritized based on high-risk processes, facilities with recent expansion or process changes and to cover any new acquisitions.

Associates

As of May 31, 2023, we employed 17,274 persons, of whom approximately 959 were represented by unions under contracts which expire at varying times in the future. We believe that all relations with associates and their unions are good.

Item 1A. Risk Factors.

As a global company of paint, coatings, roofing, construction and related products, we operate in a business environment that includes risks. Each of the risks described in this section could adversely affect the results of our operations, our financial position and/or our liquidity. Additionally, while the following factors are considered to be the more significant risk factors, no such list should be considered to be a complete statement of all potential risks and uncertainties. Unlisted risk factors may present significant additional obstacles which may adversely affect our businesses and our results. Therefore, you should carefully consider these risk factors, as well as the other information contained in this Annual Report on Form 10-K, in evaluating us, our business and your investment in us as they could cause our actual results or financial condition to differ materially from those projected in our forward-looking statements.

ECONOMIC AND STRATEGIC RISKS

Our operations and financial condition have been and could continue to be adversely affected by global and regional economic conditions in ways we may not be able to predict or control.

Our operations and financial condition have been and could continue to be adversely affected by global or regional economic conditions if markets decline in the future, whether related to a public health crisis similar to the Covid pandemic, the Russian invasion of Ukraine, higher inflation or interest rates, recession, natural disasters, impacts of and issues related to climate change, business disruptions, our ability to adequately staff operations or otherwise. Office building utilization, higher mortgage rates, and the continued shift in consumer spending to online shopping, may negatively impact office, residential, and retail construction. Additionally, escalation in interest rates, in conjunction with banking failures, may lead to financial institutions being more prudent with capital deployment and tightening lending, especially in relation to construction and real estate development. As a result, future construction activity could decrease due to a lack of financing availability, and financial distress in this sector could be further exacerbated by a lack of refinancing options available for existing real estate loans when they mature in the upcoming months. Any future economic declines may result in decreased revenue, gross margins, earnings or growth rates or difficulty in managing inventory levels or collecting customer receivables. We also have experienced, and could continue to experience, labor inflation, increased competitive pricing pressure, raw material inflation and availability issues resulting in difficulties meeting customer demand. In addition, customer difficulties in the future could result from economic declines, decreased purchasing power, public health crisis similar to the Covid pandemic, the cyclical nature of their respective businesses, such as in the oil and gas industry, or otherwise and, in turn, result in decreases in product demand, increases in bad debt write-offs, decreases in timely collection of accounts receivable and adjustments to our allowance for credit losses, resulting in material reductions to our revenues and net earnings.

Global economic and capital market conditions may cause our access to capital to be more difficult in the future and/or costs to secure such capital more expensive.

We may need new or additional financing in the future to provide liquidity to conduct our operations, expand our business or refinance existing indebtedness. Any sustained weakness in general economic conditions and/or U.S. or global capital markets could adversely affect our ability to raise capital on favorable terms or at all. From time to time we have relied, and we may also rely in the future, on access to financial markets as a source of liquidity for working capital requirements, acquisitions and general corporate purposes. Our access to funds under our credit facility is dependent on the ability of the financial institutions that are parties to that facility to meet their funding commitments. Those financial institutions may not be able to meet their funding commitments if they experience shortages of capital and liquidity or if they experience excessive volumes of borrowing requests within a short period of time. Moreover, the obligations of the financial institutions under our credit facility are several and not joint and, as a result, a funding default by one institution does not need to be made up by the others. Longer term volatility and continued disruptions in the capital and credit markets as a result of uncertainty, changing or increased regulation of financial institutions, reduced alternatives or failures of significant financial institutions could adversely affect our access to the liquidity needed for our businesses in the longer term. Such disruptions could require us to take measures to conserve cash until the markets stabilize or until alternative credit arrangements or other funding for our business needs can be arranged.

Volatility in the equity markets or interest rates could substantially increase our pension costs and required pension contributions.

We sponsor qualified defined benefit pension plans and various other nonqualified postretirement plans. The qualified defined benefit pension plans are funded with trust assets invested in a diversified portfolio of debt and equity securities and other investments. Among other factors, changes in interest rates, investment returns and the market value of plan assets can (i) affect the level of plan funding; (ii) cause volatility in the net periodic pension cost; and (iii) increase our future contribution requirements. A significant decrease in investment returns or the market value of plan assets or a significant change in interest rates could increase our net periodic pension costs and adversely affect our results of operations. A significant increase in our contribution requirements with respect to our qualified defined benefit pension plans could have an adverse impact on our cash flow.

11

A public health crisis could cause disruptions to our operations which could adversely affect our business in the future.

A significant public health crisis could cause disruptions to our operations similar to the effects of the Covid pandemic. The Covid pandemic had a negative effect on our business, results of operations, cash flows and financial condition. It affected our business due to the impact on the global economy, including its effects on transportation networks, raw material availability, production efforts and customer demand for our products. Our ability to predict and respond to future changes resulting from potential health crisis is uncertain. Even after a public health crisis subsides, there may be long-term effects on our business practices and customers in economies in which we operate that could severely disrupt our operations and could have a material adverse effect on our business, results of operations, cash flows and financial condition. As we cannot predict the duration, scope or severity of future pandemics, the negative financial impact to our results cannot be reasonably estimated and could be material.

Terrorist activities and other acts of violence or war and other disruptions have negatively impacted in the past, and could negatively impact in the future, the United States and foreign countries, the financial markets, the industries in which we compete, our operations and profitability.

Terrorist activities, acts of violence or war and other disruptions have contributed to economic instability in the United States and elsewhere, and acts of terrorism, cyber-terrorism, violence or war could affect the industries in which we compete, our ability to purchase raw materials, adequately staff our operations, manufacture products or sell or distribute products, which could have a material adverse impact on our financial condition and results of operations.

Adverse weather conditions and natural disasters, including those related to the impacts of climate change, may reduce the demand for some of our products, impair our ability to meet our demand for such products or cause supply chain disruptions which could have a negative effect on our operations and sales.

From time to time, extreme weather conditions, including natural disasters, and those related to the impacts of climate change, have had a negative effect on our operations and sales. Unusually cold or rainy weather, especially during the general construction and exterior painting season, could have an adverse effect on sales. As a result, we have historically experienced weaker sales and net income in our third fiscal quarter (December through February) in comparison to our performance during our other fiscal quarters. Events such as destructive wildfires, extreme storms or temperatures and increased flooding or other natural disasters could damage our facilities, leading to production or distribution challenges which could have a negative effect on our sales.

The impacts of these risks to our suppliers may also have a detrimental effect on the sales, manufacturing, and distribution of our products, including raw material shortages and increased costs. Any such effect on sales may result in a reduction in earnings or cash flow.

Significant foreign currency exchange rate fluctuations may harm our financial results.

We conduct business in various regions throughout the world and are therefore subject to market risk due to changes in the exchange rates of foreign currencies in relation to the U.S. dollar. Because our Consolidated Financial Statements are presented in U.S. dollars, increases or decreases in the value of the U.S. dollar relative to other currencies in which we transact business could materially adversely affect our net revenues, earnings and the carrying values of our assets located outside the United States.

FINANCIAL RISKS

The use of accounting estimates involves judgment and could impact our financial results.

The preparation of financial statements in conformity with Generally Accepted Accounting Principles (“GAAP”) requires us to make estimates and assumptions that affect reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the financial statements and reported amounts of revenues and expenses during the reporting period. Our most critical accounting estimates are described in Management’s Discussion and Analysis of Financial Condition and Results of Operations under “Critical Accounting Policies and Estimates.” Additionally, as discussed in Note P, “Contingencies and Accrued Losses,” of the Notes to Consolidated Financial Statements, we make certain estimates, including decisions related to legal proceedings and various loss reserves. These estimates and assumptions involve the use of judgment, and therefore, actual financial results may differ.

The results of our annual testing of goodwill and as-required interim testing of goodwill and other long-lived assets have required, and in the future may require, that we record impairment charges.

As of May 31, 2023, we had approximately $1.8 billion in goodwill and other intangible assets. The Accounting Standards Codification (“ASC”) section 350, "Intangibles – Goodwill and Other," requires that goodwill be tested at least on an annual basis, or more frequently as impairment indicators arise, using either a qualitative assessment or a fair-value approach at the reporting unit level. We perform our annual required impairment tests, which involve the use of estimates related to the fair market values of the reporting units with which goodwill is associated, as of the first day of our fourth fiscal quarter. The evaluation of our long-lived assets for impairment includes determining whether indicators of impairment exist, this is a subjective process that considers both internal and external factors. The impairment assessment evaluation requires the use of significant judgment regarding estimates and assumptions surrounding future results of operations and cash flows.

12

In connection with our Margin Achievement Plan 2025 ("MAP 2025") operating improvement initiative, during the fiscal third quarter ended February 28, 2023, due to declining profitability and regulatory headwinds, management decided to restructure the Universal Sealants (“USL”) reporting unit within our PCG segment, and is correspondingly exploring strategic alternatives for our infrastructure services business within the United Kingdom (“U.K.”). Due to this decision, we determined that an interim goodwill impairment assessment, as well as an impairment assessment for our other long-lived assets were required. Accordingly, we recorded an impairment loss totaling $36.7 million for the impairment of goodwill and an impairment loss of $2.5 million for the impairment of an indefinite-lived tradename in our USL reporting unit during fiscal 2023. We did not record any impairments for our definite-lived long-lived assets as a result of this assessment.

Our required annual impairment testing for goodwill and indefinite-lived intangible assets, which we performed during the fourth quarters of the fiscal years ended May 31, 2023, 2022 and 2021 did not result in an impairment charge. For discussion of the approach for, and results of, our interim and annual impairment testing for goodwill and indefinite lived intangible assets for all periods presented, please refer to the headings entitled “Goodwill” and “Other Long-Lived Assets” within the “Management’s Discussion and Analysis of Financial Condition and Results of Operations” and “Critical Accounting Policies and Estimates” sections located in “Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operation” as well as Note A(11), "Summary of Significant Accounting Policies - Goodwill and Other Intangible Assets," and Note C, "Goodwill and Other Intangible Assets," to our Consolidated Financial Statements as presented below.

In the future, if global economic conditions were to decline significantly, or if our reporting units experience significant declines in business, we may incur additional, substantial goodwill and other intangible asset impairment charges. The amount of any such impairment charge could have a material adverse effect on our results of operations.

Our significant amount of indebtedness could have a material adverse impact on our business.

Our total debt was approximately $2.7 billion at May 31, 2023 and 2022, which compares with $2.1 billion in stockholders’ equity at May 31, 2023. Our level of indebtedness could have important consequences. For example, it could:

•require us to dedicate a material portion of our cash flow from operations to make payments on our indebtedness, thereby reducing the cash flow available to fund working capital, capital expenditures, acquisitions, dividend payments, stock repurchases or other general corporate requirements;

•result in a downgrade of our credit rating, which would increase our borrowing costs, adversely affect our financial results, and make it more difficult for us to raise capital;

•restrict our operational flexibility and reduce our ability to conduct certain transactions, since our credit facility contains certain restrictive financial and operating covenants;

•limit our flexibility to adjust to changing business and market conditions, which would make us more vulnerable to a downturn in general economic conditions; and

•have a material adverse effect on our short-term liquidity if large debt maturities occur in close succession.

We cannot assure you that our business always will be able to make timely or sufficient payments of our debt. Should we fail to comply with covenants in our debt instruments, such failure could result in an event of default which, if not cured or waived, would have a material adverse effect on us.

OPERATIONAL RISKS

Operating improvement initiatives could cause us to incur significant expenses and impact the trading value of our common stock.

On May 31, 2021, we formally concluded our 2020 Margin Acceleration Plan ("MAP to Growth") operating improvement program, which resulted in significant changes in our organizational and operational structure impacting most of our companies. In August 2022, we approved and announced our MAP 2025. MAP 2025 is a multi-year restructuring plan to build on the achievements of MAP to Growth. Our MAP 2025 operating improvement program may result in significant changes in our organizational and operational structure. We have taken actions and may continue to take additional actions during future periods, in furtherance of these or other operating improvement initiatives. We may incur further expenses as a result of these actions, and we also may experience disruptions in our operations, decreased productivity and unanticipated associate turnover and the objectives of our operating improvement initiatives may not be achieved. The occurrence of any of these or other related events associated with our operating improvement initiatives could adversely affect our operating results and financial condition.

13

Fluctuations in the supply and cost of raw materials may negatively impact our financial results.

The cost and availability of raw materials, including packaging, materially impact our financial results. We obtain raw materials from a number of suppliers. Many of our raw materials are petroleum-based derivatives, minerals and metals. The cost of raw materials has in the past experienced, and likely will continue to experience, periods of volatility which have, and could in the future, increase the cost of manufacturing our products. Under normal market conditions, raw materials are generally available on the open market from a variety of sources; however, our suppliers may be impacted by social and environmental regulations and expectations, including regulations related to climate change, adverse weather conditions, pandemics, trade policy, energy availability or civil unrest, resulting in shortages or price volatility. Interruptions in the supply of raw materials or sources of energy could have a significant impact on our ability or cost to produce products.

Cost and adequate supply of raw materials is managed by establishing contracts, procuring from multiple sources, and identifying alternative materials or technology; however, the unavailability of raw materials or increased prices of raw materials that we are unable to pass along to our customers could have a material adverse effect on our business, financial condition, results of operations or cashflows.

Additionally, changes in international trade duties, tariffs, sanctions and other aspects of international trade policy, both in the United States and abroad, could materially impact the cost of raw materials. Any increase in materials that is not offset by an increase in our prices could have a material adverse effect on our business, financial condition, results of operations or cash flows.

The markets in which we operate are highly competitive and some of our competitors are much larger than we are and may have greater financial resources than we do.

The markets in which we operate are fragmented, and we do not face competition from any one company across all our product lines. However, any significant increase in competition, resulting from the consolidation of competitors, may cause us to lose market share or compel us to reduce prices to remain competitive, which could result in reduced gross profit margins. Increased competition may also impair our ability to grow or to maintain our current levels of revenues and earnings. Companies that compete in our markets include Akzo Nobel, Axalta Coating Systems Ltd., Carlisle Companies Inc., H.B. Fuller, Masco Corporation, PPG Industries, Inc., The Sherwin-Williams Company and Sika AG. Several of these companies are much larger than we are and may have greater financial resources than we do. Increased competition with these or other companies could prevent the institution of price increases or could require price reductions or increased spending to maintain our market share, any of which could adversely affect our results of operations.

Our success depends upon our ability to attract and retain key associates and the succession of senior management.

Our success largely depends on the performance of our management team and other key associates. If we are unable to attract and retain talented, highly qualified senior management and other key associates (including the ability to identify and attract key international associates), our business, results of operations, cash flows and financial condition could be adversely affected. In addition, if we are unable to effectively provide for the succession of senior management, including our Chief Executive Officer, our business, results of operations, cash flows and financial condition may be adversely affected. While we follow a disciplined, ongoing succession planning process and have succession plans in place for senior management and other key associates, these do not guarantee that the services of qualified senior executives will continue to be available to us at particular moments in time.

We depend on a number of large customers for a significant portion of our net sales and, therefore, significant declines in the level of purchases by any of these key customers could harm our business.

Some of our operating companies, particularly in the Consumer reportable segment, face a substantial amount of customer concentration. Our key customers in the Consumer reportable segment include Ace Hardware, Amazon, Do It Best, The Home Depot, Inc., Lowe’s, Menards, Orgill, True Value, W.W. Grainger, and Wal-Mart. Within our Consumer segment, sales to these customers accounted for approximately 67%, 64% and 65% of net sales for the fiscal years ended May 31, 2023, 2022 and 2021, respectively. On a consolidated basis, sales to these customers across all of our reportable segments accounted for approximately 25%, 22% and 24% of our consolidated net sales for the fiscal years ended May 31, 2023, 2022 and 2021, respectively. Sales to The Home Depot, Inc. represented less than 10% of our consolidated net sales for fiscal 2023, 2022, and 2021, and 23%, 25% and 26% of our Consumer segment net sales for fiscal 2023, 2022 and 2021, respectively. If we were to lose one or more of our key customers, experience a delay or cancellation of a significant order, incur a significant decrease in the level of purchases from any of our key customers, or experience difficulty in collecting amounts due from a key customer, our net revenues could decline materially and our operating results could be reduced materially.

14

If our efforts in acquiring and integrating other companies or product lines or establishing joint ventures fail, our business may not grow.

As an important part of our growth strategy, we intend to continue pursuing acquisitions of complementary businesses or products and creating joint ventures. Our ability to continue to grow in this manner depends upon our ability to identify, negotiate and finance suitable acquisitions or joint venture arrangements. Execution of our acquisition strategy with respect to some companies or product lines could fail or could result in unanticipated costs to us that were not apparent despite our due diligence efforts, either of which could hinder our growth or adversely impact our results of operations. In addition, acquisitions and their subsequent integration involve a number of risks, including, but not limited to:

•inaccurate assessments of disclosed liabilities and the potentially adverse effects of undisclosed liabilities;

•unforeseen difficulties in assimilating acquired companies, their products, and their culture into our existing business;

•unforeseen delays in realizing the benefits from acquired companies or product lines, including projected efficiencies, cost savings, revenue synergies and profit margins;

•unforeseen diversion of our management’s time and attention from other business matters;

•unforeseen difficulties resulting from insufficient prior experience in any new markets we may enter;

•unforeseen difficulties in retaining key associates and customers of acquired businesses;

•increased risk to our cybersecurity landscape; and

•increases in our indebtedness and contingent liabilities, which could in turn restrict our ability to raise additional capital when needed or to pursue other important elements of our business strategy.

We derive a significant amount of our revenues from foreign markets, which subjects us to additional business risks that could adversely affect our results of operations.

Our foreign manufacturing operations accounted for approximately 28.5% of our net sales for the fiscal year ended May 31, 2023, not including exports directly from the United States which accounted for approximately 0.9% of our net sales for fiscal 2023. We plan to continue to grow our international operations and the growth and maintenance of such operations could be adversely affected by a public health crises, the Russian invasion of Ukraine, war, changes in social, political and economic conditions, inflation rates, trade protection measures, restrictions on foreign investments and repatriation of earnings, changing intellectual property rights, difficulties in staffing and managing foreign operations and changes in regulatory requirements that restrict the sales of our products or increase our costs. Our ability to effectively manage our foreign operations may pose significant risks that could adversely affect our results of operations, cash flow, liquidity or financial condition.

Data privacy, cybersecurity, and artificial intelligence considerations could impact our business.

We rely on information technology systems, including tools that utilize artificial intelligence, and applications to conduct our business, including recording and processing transactions, administering human resource activities and associate benefits, manufacturing, marketing, and selling our products, researching and developing new products, maintaining and growing our businesses, and supporting and communicating with our associates, customers, suppliers and other stakeholders. The importance of such systems has increased due to many of our associates working remotely. Some of these systems and applications are operated by third parties. Additionally, we, ourselves and through our third parties, collect and process personal, confidential, and sensitive data about our business, which may include information about our customers, associates, suppliers, distributors and others. Some of this data is stored, accessible or transferred internationally. If we do not allocate and effectively manage the resources necessary to build, sustain, and protect an appropriate information technology infrastructure, or we do not effectively implement system upgrades in a timely manner, our business or financial results could be negatively impacted.

The interpretation and application of cybersecurity, artificial intelligence, biometric, and privacy laws, rules and regulations around the world applicable to our business (collectively, the “Data Protection Laws”) are uncertain and evolving. It is possible that the Data Protection Laws may be interpreted and applied in a manner that is inconsistent with our data practices. Complying with these various laws is difficult and could cause us to incur substantial costs or require us to change our business practices in a manner adverse to our business. In addition, many tools and resources we use integrate or will integrate some form of artificial intelligence which has the potential to result in bias, miscalculations, data errors, intellectual property infringement and unintended consequences. It is possible that the information technology tools we use may negatively affect our reputation, disrupt our operations, or have a material impact on our financial results.

Further, although we have implemented internal controls and procedures designed to manage compliance with the Data Protection Laws and protect our data, there can be no assurance that our controls will prevent a breach or that our procedures will enable us to be fully compliant with all Data Protection Laws. Cyber-attacks or breaches due to security vulnerabilities, associate error, supplier or third-party error, malfeasance or other disruptions may still occur. We have been and may in the future be subject to attempts to gain unauthorized access to our information technology systems and/or applications.

15

We have experienced data security incidents that have disrupted our operations, but which did not have a material impact on our financial results.

These risks may be increased as a result of an increase in remote work, a public health crisis similar to the Covid pandemic or foreign affairs such as the Russian invasion of Ukraine. In addition, it is not possible to predict the impact on our business of the future loss, alteration or misappropriation of information related to us, our associates, former associates, customers, suppliers or others. A violation of, or failure to comply with, the Data Protection Laws, a cyber-attack or a security breach of our systems could lead to negative publicity, legal claims, extortion, ransom, theft, modification or destruction of proprietary information or key information, damage to or inaccessibility of critical systems, manufacture of defective products, production downtimes, operational disruptions, data breach claims, privacy violations and other significant costs, which could adversely affect our reputation, financial condition and results of operations.

Our business and financial condition could be adversely affected if we are unable to protect our material trademarks and other proprietary information or there is a loss in the actual or perceived value of our brands.

We have numerous valuable patents, trade secrets and know-how, domain names, trademarks and trade names, including certain marks that are significant to our business, which are identified under Item 1 of this Annual Report on Form 10-K. Despite our efforts to protect our trademarks, trade secrets and other proprietary rights from unauthorized use or disclosure, other parties may attempt to disclose or use them without our authorization; such unauthorized use or disclosure could negatively impact our business and financial condition.

Similarly, the reputations of our branded products depend on numerous factors, including the successful advertising and marketing of our brand names, consumer acceptance, continued trademark validity, the availability of similar products from our competitors, and our ability to maintain product quality, technological advantages and claims of superior performance. Furthermore, the prevalence of social media increases our risk of receiving negative commentary that could damage the perception of our brands. A loss of a brand or in the actual or perceived value of our brands could limit or reduce the demand for our products and could negatively impact our business and financial condition.

Although we have insurance, it may not cover every potential risk associated with our operations.

Although we maintain insurance of various types to cover many of the risks and hazards that apply to our operations, our insurance may not cover every potential risk associated with our operations. The occurrence of a significant event, the risks of which are not fully covered by insurance, could have a material adverse effect on our financial condition and results of operations. Moreover, no assurance can be given that we will be able to maintain adequate insurance in the future at rates and with terms and conditions we consider reasonable.

If our efforts to achieve stated sustainability goals, targets or objectives fail, our business and reputation may be adversely affected.

We might fail to effectively address increased attention or expectations from the media, stockholders, activists and other stakeholders on climate change and related environmental sustainability matters. Such failure, or the perception that we have failed to act responsibly with respect to such matters or to effectively respond to new or additional regulatory requirements regarding climate change, whether or not valid, could result in adverse publicity and negatively affect our business and reputation. In addition, we have established and publicly announced goals to reduce our impact on the environment and, in the future may establish and publicly announce other goals or commitments associated with our sustainability initiatives. Our ability to achieve any stated goal, target or objective is subject to numerous factors and conditions, many of which are outside of our control, including evolving regulatory requirements. Furthermore, standards for tracking and reporting such matters continue to evolve. Our selection of voluntary disclosure frameworks and standards, and the interpretation or application of those frameworks and standards, may change from time to time or differ from those of others. Methodologies for reporting this data may be updated and previously reported data may be adjusted to reflect improvement in availability and quality of data, changing assumptions, changes in the nature and scope of our operations and other changes in circumstances, which could result in significant revisions to our current goals, reported progress in achieving such goals, or ability to achieve such goals in the future. If we fail to achieve, are perceived to have failed, or are delayed in achieving these goals and commitments, it could negatively affect investor confidence in us, as well as expose us to government enforcement actions and private litigation.

16

LEGAL AND REGULATORY RISKS

The industries in which we operate expose us to inherent risks of legal and warranty claims and other litigation-related costs, which could adversely impact our business.

We face an inherent risk of legal claims if the exposure to, or the failure, use, or misuse of our products results, or is alleged to result, in bodily injury and/or property damage. In the course of our business, we are subject to a variety of inquiries and investigations by regulators, as well as claims and lawsuits by private parties, including those related to product liability, product claims regarding asbestos or other chemicals or materials in our products, warranties, the environment, employment matters, contracts, service contracts, intellectual property and commercial matters, which due to their uncertain nature may result in losses, some of which may be material. We are defending claims and class action lawsuits, and could be subject to future claims and lawsuits, in which significant financial damages are alleged. These matters could consume material financial resources to defend and be a distraction to management. Some, but not all, of such matters are insured. We offer warranties on many of our products, as well as long term warranty programs at certain of our businesses and, as a result, from time to time we may experience higher levels of warranty expense, which is typically reflected in selling, general and administrative expenses. The nature and extent to which we use hazardous or flammable materials in our manufacturing processes creates risk of damage to persons and property that, if realized, could be material.

Compliance with environmental, health and safety laws and regulations could subject us to unforeseen future expenditures or liabilities, which could have a material adverse effect on our business.

We are subject to numerous, complicated and often increasingly stringent environmental, health and safety laws and regulations, including those developed in response to climate change, in the jurisdictions where we conduct business and sell our products. Governmental and regulatory authorities impose various laws and regulations on us that relate to environmental protection, the use, sale, transportation, import and export of certain chemicals or hazardous materials, and various health and safety matters, including the discharge of pollutants into the air and water, the handling, use, treatment, storage and clean-up of solid and hazardous wastes, the use of certain chemicals in product formulations, and the investigation and remediation of soil and groundwater affected by hazardous substances and those related to climate change. These laws and regulations include the Clean Air Act, the Clean Water Act, RCRA, CERCLA, TSCA, DSL, REACH and many other federal, state, provincial, local and international statutes. These laws and regulations often impose strict, retroactive and joint and several liability for the costs of, and damages resulting from, not addressing our, or our predecessors’ past or present facilities and third-party disposal sites. We are currently undertaking remedial activities at a number of our properties and could be subject to future liability as yet unknown, but that could be material.

We have not always been and may not always be in full compliance with all environmental, health and safety laws and regulations in every jurisdiction in which we conduct our business. In addition, if we violate or fail to comply with environmental, health and safety laws (including related to permitting), we could be fined or otherwise sanctioned by regulators, including enjoining or curtailing operations or sales, remedial or corrective measures, installing pollution control equipment, or other actions. We have been and also could in the future be liable for consequences arising out of human exposure to hazardous substances or chemicals of concern relating to our products or operations. Accordingly, we cannot guarantee that we will not be required to make additional expenditures to remain in or to achieve compliance with environmental, health or safety laws or changes in stakeholder preferences or expectations in the future or that any such additional expenditures will not have a material adverse effect on our business, financial condition, results of operations or cash flows. If regulatory permits or registrations are delayed, restricted, or rejected, subsequent operations at our businesses could be delayed or restricted, which could have an adverse effect on our results of operations.

Our businesses are subject to varying domestic and foreign laws and regulations that may restrict or adversely impact our ability to conduct our business.

Our businesses are subject to varying domestic and foreign laws and regulations that may restrict or adversely impact our ability to conduct our business. These include securities, environmental, health, safety, tax, competition and anti-trust, insurance, service contract and warranty, trade controls, data security, anti-corruption, anti-money laundering, wage and hour employment and privacy laws and regulations. These laws and regulations change from time to time and thus may result in increased risk and costs to us related to our compliance therewith. From time-to-time regulators review our compliance with applicable laws. We have not always been, and may not always be, in full compliance with all laws and regulations applicable to our business and, thus enforcement actions, fines and private litigation claims and damages, which could be material, may occur, notwithstanding our belief that we have in place appropriate risk management and compliance programs to mitigate these risks.

We could be adversely affected by violations of the U.S. Foreign Corrupt Practices Act and similar anti-bribery laws of other countries, as well as trade sanctions administered by the office of Foreign Assets Control and the Department of Commerce.

The U.S. Foreign Corrupt Practices Act and similar anti-bribery laws of other countries generally prohibit companies and their intermediaries from making improper payments to governmental officials or others for the purpose of obtaining or retaining business or for other unfair advantage. Our policies mandate compliance with anti-bribery laws. We operate in many parts of the world that have experienced governmental corruption to some degree and, in certain circumstances, strict compliance with anti-bribery laws may conflict with local customs and practices.

We are required to comply with U.S. regulations on trade sanctions and embargoes administered by the U.S. Department of the Treasury, Office of Foreign Assets Control, the Commerce Department and similar multi-national bodies and governmental agencies worldwide, which are complex and often changing. A violation thereof could subject us to regulatory enforcement actions, including a loss of export privileges and significant civil and criminal penalties and fines.

Although we have internal controls and procedures designed to ensure compliance with these laws, there can be no assurance that our controls and procedures will prevent a violation of these laws. Violations of these laws, or allegations of such violations, could disrupt our business and result in a material adverse effect on our results of operations, financial condition, and cash flows.

We could be adversely affected by or incur liability for the actions or inaction of our third parties.

We vet and monitor our business partners and companies that we engage in an effort to ensure that the business practices of those third parties are in compliance with applicable laws and regulations and industry best practices, including applying appropriate technical security measures, safeguarding human rights and preventing illegal trade. In the event one of our third parties experiences a data breach, is found to have violated applicable laws or regulations, or the business practices of the third party come under public scrutiny, we could be subject to legal claims, fines and reputational damage related to the third-party relationship. In the event any third-party legal violation or business practice requires us to severe the third-party relationship, we could also experience an impact on our services, operations or our ability to obtain raw materials for our products.

Our operations are subject to the effect of global tax law changes, some of which have been, and may be in the future, retroactive in application.

Our operations are subject to various federal, state, local and foreign tax laws and regulations which govern, among other things, taxes on worldwide income. Any potential tax law changes may, for example, increase applicable tax rates, have retroactive application, or impose stricter compliance requirements in the jurisdictions in which we operate, which could reduce our consolidated net earnings.

In response to, for instance, an economic crisis or recession, governments may revise tax laws, regulations or official interpretations in ways that could have a significant impact on us, including modifications that could, for example, reduce the profits that we can effectively realize from our non-U.S. operations, or that could require costly changes to those operations, or the way in which they are structured. If changes in tax laws, regulations or interpretations were to significantly increase the tax rates on non-U.S. income, our effective tax rate could increase, our profits could be reduced, and if such increases were a result of our status as a U.S. company, could place us at a disadvantage to our non-U.S. competitors if those competitors remain subject to lower local tax rates.

We could be adversely affected by failure to comply with federal, state and local government procurement regulations and requirements.

We have contracts with and supply product to federal, state and local governmental entities and their contractors, and are required to comply with specific procurement regulations and other requirements relating to those contracts and sales. Requirements in our contracts and those requirements flowed down to us in our capacity as a subcontractor or supplier, although customary in government contracts, may impact our performance and compliance costs. Failure to comply with these regulations and requirements or to make required disclosures under contract could result in reductions of the value of contracts, contract modifications or termination for cause, adverse past performance ratings, actions under a federal or state false claims statutes, suspension or debarment from government contracting or subcontracting for a period of time and the assessment of penalties and fines, any of which could negatively impact our results of operations and financial condition and could have a negative impact on our reputation and ability to procure other government contracts in the future.

We lease certain of our properties under long-term leases. Some of these leases provide for increased rent based on an increase in the cost-of-living index. For information concerning our rental obligations, see Note M, “Leases,” to the Consolidated Financial Statements. Under many of our leases, we are obligated to pay certain varying insurance costs, utilities, real property taxes and other costs and expenses.

We believe that our manufacturing plants and office facilities are well maintained and suitable for our operations.

Item 3. Legal Proceedings.

Environmental Matters

Like other companies participating in similar lines of business, some of our subsidiaries are identified as a “potentially responsible party” under the federal Comprehensive Environmental Response, Compensation and Liability Act and similar local environmental statutes or are participating in the cost of certain clean-up efforts or other remedial actions relating to environmental matters. Our share of such costs to date, however, has not been material and management believes that these environmental proceedings will not have a material adverse effect on our consolidated financial condition or results of operations. See “Item 1 — Business — Environmental Matters,” in this Annual Report on Form 10-K.

As permitted by SEC Rules and given the size of our operations, we have elected to adopt a quantitative disclosure threshold for environmental proceedings of $1 million. As of the date of this filing, we are not aware of any matters that exceed this threshold and meet the definition for disclosure.

Item 4. Mine Safety Disclosures

Not applicable.
