Item 1. Business

Overview

WD-40 Company is a global marketing organization dedicated to creating positive lasting memories by developing and selling products that solve problems in workshops, factories and homes around the world. The Company was founded in 1953 and is headquartered in San Diego, California.

For more than four decades, we sold only one product, WD-40® Multi-Use Product, a multi-purpose maintenance product which acts as a lubricant, rust preventative, penetrant and moisture displacer. Over the last several decades, we have evolved and expanded our product offerings through both research and development activities and through the acquisition of several of our smaller brands worldwide. As a result, we have built a family of brands and product lines that deliver high quality performance at a good value to our end users.

We currently market and sell our products in more than 176 countries and territories worldwide primarily through hardware stores, automotive parts outlets, industrial distributors and suppliers, mass retail and home center stores, value retailers, grocery stores, online retailers, warehouse club stores, farm supply stores, sport retailers, and independent bike dealers.

Our sales come from two product groups – maintenance products and homecare and cleaning products. Maintenance products are sold worldwide in markets throughout North, Central and South America, Asia, Australia, Europe, India, the Middle East and Africa. Homecare and cleaning products are sold primarily in North America, the United Kingdom (“U.K.”) and Australia. We sold certain assets of the homecare and cleaning product brands in the EIMEA segment in the fourth quarter of fiscal year 2025. See Note 3. Assets Held for Sale of the consolidated financial statements, included in Item 15 of this report for additional information on this sale. These brands are included in the results of operations in the consolidated statements of operations for fiscal year 2025. We continue to make available for sale certain assets of our homecare and cleaning product portfolios in the Americas segment and are expecting the sale of these portfolios in fiscal year 2026. This potential sale will allow us to focus on our core, higher-margin maintenance products that are included in our strategic framework. The principal driver of our sales growth is focused on our maintenance products and making them available in more places, for more people, who we expect will find more uses, more frequently.

Table of Contents

Our future is guided by a long-term four-by-four strategic framework tied to our purpose and our values. There are two main elements of our strategic framework.

The first element of our four-by-four strategic framework, which we refer to as our Must-Win Battles, focuses on increasing sales of our maintenance products. Our four Must-Win Battles include:

1.growing WD-40 Multi-Use Product sales through geographic expansion;

2.growing sales and gross margin through the premiumization of WD-40 Multi-Use Product;

3.growing the WD-40 Specialist product line through category leadership; and

4.accelerating our capabilities in building our brand digitally and maximizing our global digital commerce presence.

The second element of our four-by-four strategic framework, which we refer to as our Strategic Enablers, focuses on operational excellence. Our four Strategic Enablers include:

1.ensuring a people-first mindset where we can attract, develop and engage outstanding employees;

2.building a sustainable business for the future;

3.achieving operational excellence in supply chain; and

4.driving productivity through enhanced systems.

These elements are the foundation of our four-by-four strategic framework and are where we will continue to focus our time, talent and resources.

We continue to be focused and committed to innovation and renovation of our products. We see innovation and renovation as important factors to the long-term growth and enhancing the sustainability of our brands and product lines. We intend to continue to work on future products, product lines, product packaging, and product delivery systems, as well as promotional innovations and renovations to expand our product portfolio, build a more sustainable future, and to help us grow. We are also focused on expanding our current brands in existing markets with new product development. Our research and development team supports new product development and current product improvement for our brands. Over the years, the impact of our research and development team on most of our brands and products has been reflected through our innovation. Key innovations for our products include, but are not limited to, WD-40 EZ-Reach Flexible Straw®, WD-40 Smart Straw®, WD-40 Trigger Pro®, WD-40 Specialist®, WD-40 Specialist® Degreaser & Cleaner EZ-Pods, WD-40® Precision Pen, WD-40 BIKE®, 3-IN-ONE RVcare® and 3-IN-ONE® Professional Garage Door Lube.

Our homecare and cleaning products in the Americas and Asia-Pacific segments are considered harvest brands, which continue to provide positive returns but are becoming a smaller part of the business as sales of the maintenance products grow with the execution of our four Must Win Battles within our strategic framework. We have continued to sell products within these brands but with a reduced level of marketing investment over time.

Human Capital Resources

Our purpose can only be achieved with the efforts of our 714 employees who live our values and create positive lasting memories for our stakeholders, including end users solving problems in factories, workshops, and homes around the world. Our workforce is distributed globally in 18 countries, with approximately 35% in the Americas, 40% in EIMEA, 15% in Asia-Pacific, and 10% corporate employees. Women make up approximately 46% of our global workforce. The average tenure of our global workforce is eight years and our average employee retention rate is greater than 90%.

Our purpose-driven and values-guided culture generates an important competitive advantage through our ability to attract, develop, retain and engage outstanding people. Consistently living our company values grants each of us the freedom to make autonomous decisions in the best interest of all stakeholders. We are committed to celebrating diversity of thought and lived experiences, providing equitable access to opportunities, and creating a culture where everyone experiences a sense of inclusion and belonging.

We are a meritocracy with a competitive performance-based total rewards strategy, where compensation and career advancement are determined by demonstrated competencies and contributions. Our calendar year 2023 global pay equity study reaffirmed there were not statistically significant or systemic gender-based pay disparities, ensuring all compensation decisions were rooted in job-related criteria with no evidence of biased decision-making. The Compensation and People Committee of our Board of Directors provides oversight of our relevant people-management practices.

Our workforce is comprised of the following functions: marketing, sales, customer service, finance and accounting, investor relations, legal, information technology, human resources, supply chain and logistics, innovation, research and

development, environmental programs, quality, and other technical fields. The success of our teams is accelerated through global collaboration and our bold ambition to become a world-class learning organization.

Products

Homecare and Cleaning Products

We sell our homecare and cleaning products in certain locations worldwide and they include a portfolio of well-known brands. We are pursuing the sale of certain assets of these portfolios in the Americas segments in fiscal year 2026 and are

Table of Contents

classified as held for sale. Certain of our homecare and cleaning product brands will continue to be held for use due to their significance to the business within certain regional markets in the Asia-Pacific segment.

We are actively pursuing the sale in fiscal year 2026 of the following homecare and cleaning product brands in the Americas segment:

2000 Flushes® – The 2000 Flushes brand is a line of long-lasting automatic toilet bowl cleaners. It includes a variety of formulas, including the Bleach and Blue plus Bleach that has a unique EPA-approved “kills bacteria” claim. 2000 Flushes is sold primarily in the U.S. and Canada through grocery and mass retail channels as well as through online retailers.

We sold certain assets of the homecare and cleaning product brands in the EIMEA segment in the fourth quarter of fiscal year 2025. See Note 3. Assets Held for Sale of the consolidated financial statements, included in Item 15 of this report for additional information on this sale. These brands are included in the results of operations in the consolidated statements of operations for fiscal year 2025:

1001® and 1001 Carpet Fresh® – The 1001 brand is a line of room and rug deodorizers sold as powder and aerosol quick-dry foam products. These products were sold primarily through grocery, mass, and value retail channels as well as through online retailers in the U.K. In the U.K., these products were sold under the 1001® and 1001 Carpet Fresh® brand names.

Sales and Marketing

Our sales do not reflect any significant degree of seasonality. However, it is common for our sales to fluctuate from period to period or year to year due to various factors including, but not limited to, new or lost distribution, the timing of customer orders particularly in distributor markets, the number of product offerings carried by a customer and the level of promotional activities and programs being run at customer locations. New or lost distribution occurs when we gain or lose customers, when we gain or lose store count for a customer or when our products are added to new locations within a store or removed from existing locations. From time to time, as part of new product offering launches, we may gain access to entirely new distribution channels. The number of product offerings refers to the number of brands and/or the number of products within each of those brands that our customers offer for sale to end users. The level of promotional activities and programs relates to the number of events or volumes of purchases by customers in support of off-shelf or promotional display activities. Changes in any one of these three factors or a combination of them can cause our sales levels to increase or decrease from period to period. Promotional activities can also be impacted by customers adjusting to price increases and other market disruptions. It is also common and/or possible that we could lose distribution or product offerings and

Table of Contents

experience a decrease in promotional activities and programs in one period and subsequently regain this business in a future period. We are accustomed to such fluctuations and manage this as part of our normal business activities.

Manufacturing

We outsource our finished goods manufacturing directly or through our marketing distributors to various third-party manufacturers. We or our marketing distributors use contract manufacturers in the U.S., Mexico, Brazil, Argentina, Colombia, the U.K., Italy, Poland, Australia, China, the Middle East, South Korea and India. The Company has minimum purchase obligations that primarily consist of contractual volume commitments with certain third-party packagers. See Note 14. commitments and contingencies of the consolidated financial statements, included in Item 15 of this report for additional information on minimum purchase obligations. We also formulate and manufacture concentrate used in our WD-40 products at certain of our own facilities and at third-party contract manufacturers.

In addition to the commitments to purchase products from contract manufacturers described above, we may also enter into commitments with other manufacturers from time to time to purchase finished goods and components to support innovation or supply chain initiatives.

Sources and Availability of Components and Raw Materials

We rely on a limited number of third-party contract manufacturers and component suppliers, including single or sole-sourced suppliers, for certain of our raw materials, packaging, product components and other necessary supplies. Where possible and where it makes business sense, we work with secondary or multiple suppliers to qualify additional supply sources. Historically, we have been able to obtain adequate capacity and raw materials. The primary components and raw materials for most of our products include specialty chemicals and aerosol cans, which are manufactured from commodities that are subject to market price fluctuations. The availability of these components and raw materials is affected by a variety of supply and demand factors, including global market conditions, tariffs imposed by the U.S. or foreign governments, plant capacity utilization, and natural disasters. We have historically experienced input cost inflation that impacted the cost of certain raw materials and freight services. As a result, we took actions to increase prices with our customers to help mitigate some of these inflationary pressures. We also implemented cost savings initiatives to mitigate those pressures. Our business results depend on the effective management and remedy of any supply disruptions. While we expect these components and raw materials to continue to be readily available in the future, we have developed sourcing alternatives and risk mitigation plans.

Research and Development

We recognize the importance of innovation and renovation to our long-term success and are focused on and committed to research and new product development activities, primarily in our maintenance product group. Our product development team engages in consumer research, product development, current product improvement and testing activities. The product development team also leverages its development capabilities by partnering with a network of outside resources including our current and prospective outsource suppliers. In addition, the research and development team engages in activities and product development efforts which are necessary to ensure that we meet regulatory requirements for the formulation of our products. The research and development team also helps shape our environmental goals and business objectives by innovating and implementing sustainable practices and products. Our research and development team currently conducts global testing at a laboratory facility that we lease in New Jersey.

Competition

The markets for our products are highly competitive and influenced by large retailers with significant negotiating power. Current trends among these large retailers include increased demand for new innovative products and marketing, requiring suppliers to maintain or reduce product prices and to deliver products within shorter lead times. Our products compete both within their own product classes as well as within product distribution channels, competing with many other products for store placement and shelf space. Competition in international markets varies by country. We are aware of many competing products, some of which sell for lower prices or are produced and marketed by companies with greater financial resources than those of our Company. We rely on the awareness of our brands among end users, the value offered by those brands as perceived by consumers, product innovation and renovation and our multiple channel distributions as our primary strategies. New products and our entry into new markets typically encounter intense competition, which may require significant investments in advertising and promotional activities. When a new product achieves end user acceptance, ongoing advertising and promotional support may be required to maintain its relative market position.

Trademarks and Patents

Item 1A. Risk Factors

The following risks and uncertainties, as well as other factors described elsewhere in this report or in our other SEC filings, could materially harm our business, financial condition and results of operations. The risks and uncertainties we have described are not the only ones we face. Additional risks and uncertainties not currently known to us or that we currently deem immaterial may also harm our business, financial condition and results of operations.

Global economic conditions may negatively impact our financial condition and results of operations.

Adverse developments in the global economy or key regional economies, a reduction in industrial outputs, or decreases in consumer spending or confidence could significantly decrease purchases of our products by our customers and end users. Consumer purchases of discretionary items, which could include our maintenance products and homecare and cleaning products, may decline during periods where disposable income is reduced or there is economic uncertainty, which would negatively impact our financial condition and results of operations. During unfavorable or uncertain economic times, end users may also increase purchases of lower-priced or non-branded products and our competitors may increase their level of advertising and promotional activities to spur sales, both of which may negatively impact our financial condition and results of operations.

In addition, our sales and operating results may be affected by uncertain or changing economic and market conditions, including recession, inflation, deflation, tariffs and other geopolitical trade disruptions, prolonged weak consumer demand, political instability, public health crises and natural disasters or other changes that may affect the principal markets, trade channels, and industrial segments in which we conduct our business. In the past, global supply chain issues and other macroeconomic factors resulted in an inflationary environment that led to increased raw material and other input costs. Future occurrences of inflationary environments or constraints in our supply chain and distribution networks, either globally or in key regions, may unfavorably impact our gross margin and operating results. The severity and duration of any recession or inflationary environment are uncertain and it is not possible to predict the extent to which such conditions will impact our financial results and operations in the future. It is also uncertain how such changes in recessionary or

Table of Contents

inflationary conditions could impact demand from our customers and end users. A decrease in demand from our customers and end users would harm our financial results.

If economic or market conditions in certain of our key markets deteriorate, we may experience material adverse effects on our business, financial condition and results of operations. Adverse economic and market conditions could also harm our business by negatively affecting the parties with whom we do business, including our customers, retailers, distributors and wholesalers, and third-party contract manufacturers and suppliers. Such conditions could impair the ability of our customers to pay for products they have purchased from us. As a result, allowances for credit losses and write-offs of accounts receivable from our customers may increase. In addition, our third-party contract manufacturers and their suppliers may experience financial difficulties or business disruptions that could negatively affect their operations and their ability to supply us with finished goods and the raw materials, packaging, and components required for our products.

Global operations outside the U.S. expose us to uncertain conditions, foreign currency exchange rate risk and other risks in international markets.

Our sales outside the U.S. were approximately 66% of consolidated net sales in fiscal year 2025. As a result, our ability to execute our strategic framework will continue to face substantial risks associated with having increased global operations outside the U.S., including, but not limited to:

•economic or political instability in any of our global markets;

•challenges associated with conducting business in foreign jurisdictions, including those related to our understanding of and compliance with business laws and regulations in such foreign jurisdictions;

•increasing tax complexity or changes in tax law associated with operating in multiple tax jurisdictions;

•a dispersed employee base and requirements for compliance with varied employment regulations and labor laws, including health and safety regulations and wage and hour laws, in countries outside the U.S.;

•varying and complex privacy laws in foreign jurisdictions; and

•the imposition of tariffs or trade restrictions and costs, burdens and restrictions associated with other governmental actions.

These risks could have a significant impact on our ability to sell our products on a competitive basis in global markets outside the United States. In addition, continued developments in global political climates have introduced greater uncertainty with respect to tax policies, trade relations, tariffs and government regulations affecting trade between the U.S. and other countries. For example, in April 2025, the U.S. government announced a number of tariffs on countries which include those we trade with for certain input costs to our products. Certain of these inputs sourced by our third-party manufacturers to produce our products may increase in cost which may result in our inability to purchase sufficient inventory of inputs for production to meet customer demand and in turn impact our results. In addition, any supply chain constraints, inflationary impacts, additional or heightened tariffs or weakening in consumer demand as a result of changes to global economic conditions could impact our results. The ongoing Russia-Ukrainian war and recent conflicts in the Middle East have periodically disrupted global markets and contributed to increased market volatility and other disruptions. More disruptions could occur as a result of any number of events including military conflicts, geopolitical developments, and war. These disruptions could lead to delays in supply and manufacturing which could damage our current and prospective customer relationships. Commodity markets remain subject to heightened levels of volatility, especially as they relate to the price of certain specialty chemicals. The duration and severity of such volatility in the price of certain specialty chemicals are highly unpredictable and may unfavorably impact our cost of products sold for as long as these conditions exist. These developments, as well as the risks outlined above, could have a material adverse effect on our business, financial condition and results of operations.

Approximately 51% of our revenues in fiscal year 2025 were generated in currencies other than the U.S. Dollar, which is our reporting currency. In addition, all our foreign operating subsidiaries have functional currencies other than the U.S. Dollar, and our largest subsidiary is in the U.K. and generates significant sales in Euros and Pounds Sterling. As a result, we are exposed to foreign currency exchange rate risk with respect to our sales, expenses, profits, cash and cash equivalents, other assets and liabilities denominated in currencies other than the U.S. Dollar. Our financial results are negatively impacted when the foreign currencies in which our subsidiary offices operate weaken relative to the U.S. Dollar.

Table of Contents

Conversely, a sustained weakening of the U.S. Dollar can have broad economic impacts that can include, but are not limited to, increased inflationary conditions in the U.S market that impacts the purchasing power of end users and could lower consumer demand. Although we use instruments to hedge certain foreign currency risks, primarily those associated with our U.K. subsidiary and net assets denominated in non-functional currencies, we are not fully protected against foreign currency fluctuations and, therefore, our reported earnings are affected by changes in foreign currency exchange rates. Moreover, any favorable impacts to profit margins or financial results from fluctuations in foreign currency exchange rates are likely to be unsustainable over time.

Additionally, our global operations outside the U.S. are subject to risks relating to appropriate compliance with legal and regulatory requirements in local jurisdictions, potential difficulties in staffing and managing local operations, potentially higher incidence of fraud or corruption, credit risk of local customers and distributors and potentially adverse tax consequences. As we further develop and grow our business operations outside the U.S., we are exposed to additional complexities and risks, particularly in China, Mexico, Brazil and other emerging markets. In many foreign countries, particularly in those with developing economies, business practices that are prohibited by the U.S. Foreign Corrupt Practices Act, the U.K. Bribery Act or other applicable anti-corruption laws and regulations may be prevalent. Evolving privacy and anti-trust laws and regulations in Europe, the U.S. and other jurisdictions present additional risks. Any failure to comply with these laws, even if inadvertent, could result in significant penalties or otherwise harm our reputation and business. Although we have adopted policies and contract terms to mandate compliance with these laws, there can be no assurance that all our employees, contractors and agents will comply with our requirements. Violations of these laws could be costly and disrupt our business, which could have a material adverse effect on our business, financial condition and results of operations.

Our business and financial results could suffer if we are unable to attract, retain and motivate talented employees, including senior management, and maintain our corporate culture’s relevance to our strategic plan.

Our success depends on our continuing ability to attract, engage, and develop highly qualified people who are committed to our culture. This ability creates an environment where people wish to build their careers, and the resulting retention of talent is a competitive advantage. We may be unable to attract, hire, develop and deploy talented employees in new markets and at the scale required by the growth of our business. In addition, our future success may increasingly depend on highly skilled employees with proficiency in working with artificial intelligence (“AI”), machine learning and other emerging technologies. Competition for these employees is intense and entities with more substantial resources may pursue this talent more aggressively. Our future performance depends in significant part on maintaining high levels of employee engagement and nurturing our values and culture. We believe that our company culture is a critical driver of our success and we invest substantial time and resources in building, maintaining and evolving our culture. Any failure to preserve and evolve our culture to maintain its relevance to our strategy could negatively affect our future success, including our ability to recruit, engage and retain employees. Our success also depends on the continued service of our executive officers, key employees and other talented people. Further, our ability to successfully execute organizational changes, including succession planning and the transition of our executive officers and key employees, is critical to the continued success of our business. The unexpected loss of the services of key employees or executive officers could have a material adverse effect on our business and prospects. In addition, certain economic conditions have led to competitive pressures in labor markets in which experienced personnel are in high demand. Since the competition for such talent is intense there can be no assurance that we can retain our key employees or attract, assimilate and retain employees who are fully engaged in the future. If we are unable to implement and successfully manage the initiatives associated with our strategic framework in accordance with our business plans, our business and financial results could be adversely affected. Moreover, there is no certainty that the implementation of the initiatives associated with our strategic framework will advance our business or financial results as intended.

If the success and reputation of one or more of our leading brands erodes, our business, financial condition and results of operations could be negatively impacted.

Our financial success is directly dependent on the success and reputation of our brands, particularly our WD-40 Brand. The success and reputation of our brands can suffer if marketing plans or product development and improvement initiatives, including the release of new products or innovative packaging, do not have the desired impact on the brands’ image or do not attract customers as intended. Our brands can also be adversely impacted due to the activities and pressures placed on them by our competitors. Further, our business, financial condition and results of operations could be negatively impacted if one of our leading brands suffers damage to its reputation due to real or perceived quality or safety issues. Quality issues, which can lead to large scale recalls of our products, can be due to product contamination, regulatory non-compliance, packaging errors, incorrect ingredients or components in our product or low-quality ingredients in our products due to

Table of Contents

suppliers delivering items that do not meet our specifications. Product quality issues, which could include lower product efficacy due to formulation changes attributable to regulatory requirements, could also result in decreased customer confidence in our brands resulting in lower sales and a decline in product quality could result in product liability claims. In addition, our brand value depends on our ability to maintain a positive consumer perception of our corporate integrity and brand culture. Negative claims or publicity involving us or our brand influencers, our products, or any of our key employees could damage our reputation and brand image, regardless of whether such claims have merit. This risk is compounded by the increasing use of social and digital media and networking sites by consumers, and the speed by which information and opinions are disseminated. If we are unable to anticipate or respond to various challenges in the marketplace, including trends in the market and changing consumer demands and sentiment, our financial results may be negatively impacted. Although we dedicate significant resources to brand protection in an effort to prevent or minimize brand erosion and maintain and enhance our reputation and the reputation of our brands, there can be no assurance that such efforts will be successful.

We face competition in our markets which could lead to reduced sales and profitability.

We encounter competition from similar and alternative products, many of which are produced and marketed by major national or multinational companies. In addition, we frequently discover products in certain markets that are infringing or counterfeit reproductions of our products. The availability of counterfeits and other infringing products, particularly in China and other emerging markets, could adversely impact our sales and potentially damage the value and reputation of our brands.

Our products generally compete on the basis of brand recognition, product performance, quality, price, or other benefits to consumers and meeting end users’ needs. Advertising, promotions, merchandising and packaging also have a significant impact on consumer purchasing decisions. A newly introduced consumer product, whether improved or recently developed, usually encounters intense competition requiring substantial expenditures for advertising, sales and consumer promotion. Product adoption or consumer acceptance often requires sustained advertising, promotional support and product improvements in order to maintain or gain its relative market position.

Some companies with products that compete against our homecare and cleaning products have financial, management and operational resources greater than ours. These competitors may be able to spend more aggressively on advertising and promotional activities, introduce competing products more quickly and respond more effectively to changing business and economic conditions than us or have better economies of scale than we do. In addition, although our maintenance products often hold strong positions in certain markets, larger diversified companies may enter this market and leverage substantial resources and brand recognition to offer new competing products, which could have an adverse effect on our business, financial condition and results of operations.

Competitive activity may require us to increase our investment in marketing or reduce our sales prices, either of which would lead to reduced profit margins, or a potential loss of market share or loss of distribution, each of which could have a material adverse effect on our business, financial condition and results of operations. There can be no assurance that we will be able to compete successfully against current and future competitors or that competitive pressures faced by us or the infringement of our products and brands will not have a material adverse effect on our business, financial condition and results of operations.

Sales unit volume growth may be difficult to achieve.

Our ability to achieve sales volume growth will depend on our ability to (i) execute the initiatives associated with our strategic framework, (ii) drive growth in new geographic markets by making targeted end users aware of our products and expanding distribution and market channels, including digital commerce, (iii) drive growth within our existing markets through innovation, renovation and enhanced merchandising and marketing of our established brands, and (iv) capture market share from our competitors. It is more difficult for us to achieve sales volume growth in developed markets where our products are widely used as compared to developing or emerging markets where our products are newly introduced or are not as well known by consumers or as widely distributed. To protect our existing market share or capture additional market share from our competitors, we may need to increase our expenditure related to promotions and advertising or introduce and establish new products or product lines. In addition, we periodically implement sales price increases within certain markets or for certain product lines in response to increased costs associated with components, raw materials, manufacturing and distribution. For example, we implemented significant sales price increases during fiscal years 2022 and 2023 in response to significant increases in our cost of products sold caused by the inflationary environment during that time. Sales price increases to offset rising costs or the impact of tariffs may slow sales volume growth or cause declines in

Table of Contents

volume in the short term as customers and end users adjust to sales price increases or purchase alternative products at lower prices. We may lose a portion of our end-user base with steep price actions. In addition, the continued popularity and growth of the online retail sales channel presents both us and our customers that sell our products online with the challenge of balancing online and physical store retailing methods. Alternative retail channels could become more prevalent than the traditional retailers upon whom we rely for the majority of our business and operating profit. As a result of changes in end-user preference, sales are increasingly shifting to these online retail sales channels, and this shift may present a challenge in our markets where we have a less developed e-commerce business. Although we are engaged in e-commerce with respect to our products, if we are not successful in expanding sales in such alternative retail channels or we experience challenges with operating in such channels, our financial condition and results of operations may be negatively impacted. In addition, a change in the strategies of our existing customers, including shelf simplification, the discontinuation of certain product offerings or the shift in shelf space to competitors’ products could reduce our sales and potentially offset sales volume increases achieved as a result of other sales growth initiatives. If we are unable to increase market share in our existing product lines by developing product improvements, investing adequately in our existing brands, building usage among existing and new end users, developing, acquiring or successfully launching new products or product line extensions, or successfully penetrating emerging and developing markets and sales channels globally, we may not achieve our sales volume growth objectives.

Cost volatility in finished goods, components, raw materials, transportation and other supplies or services could harm our financial condition and results of operations.

Volatility in the cost of finished goods, which may be driven by cost volatility for components, raw materials and third-party manufacturing fees, as well as volatility in the cost of transportation and other supplies or services may harm our financial condition and results of operations. Specialty chemicals and aerosol cans, which constitute a significant portion of the costs for many of our maintenance products, have experienced significant price volatility in the past, and may do so in the future. In particular, volatility in the price of oil indirectly impacts the cost of specialty chemicals, many of which are indexed to oil related refined products. Fluctuations in gasoline and diesel fuel prices, driven in part by crude oil price volatility, fluctuations in costs of cans including those related to the impact of tariffs, increased regulations imposed on the freight industry, and higher demand for transportation services as e-commerce grows have impacted the cost of transporting our products, the loss of low-cost trucking companies that provide ground transport for our aerosol products, and additional macroeconomic factors which have resulted in increased freight costs. Our business operations could be adversely affected by labor disputes, strikes, or lockouts particularly those involving the employees of our suppliers and contractors. Any such disruptions could lead to delays in production, increased costs, and potential loss of revenue. For example, the COVID-19 pandemic resulted in global supply chain constraints and transportation disruptions that led to increased competition for freight resources, higher fees charged by our third-party manufacturers, increased raw material costs and other input costs that negatively impacted our results of operations. In the past, other macroeconomic factors resulted in an inflationary environment that compounded these impacts and led to further increases in raw material costs, manufacturing and distribution costs, and other input costs. When there are significant increases in the costs of components, raw materials, third-party manufacturing fees and other expenses, and we are not able to increase the prices of our products or achieve other cost savings to an extent that they will offset such cost increases, our gross margin and operating results will be negatively impacted.

In addition, if we increase our sales prices in response to increases in the cost of such raw materials, and those raw material costs later decline significantly, we may not be able to sustain our sales prices at these higher levels. As component and raw material costs are the principal contributors to the cost of products sold for all of our products, any significant fluctuation in the costs of components and raw materials could have a material impact on the gross margins realized on our products. Sustained increases in the cost of raw materials, components, fees from our third-party contract packagers, transportation and other necessary supplies or services, or significant volatility in such costs, could have a material adverse effect on our financial condition and results of operations.

Reliance on a limited base of third-party contract manufacturers, logistics providers and suppliers of raw materials and components may result in disruption to our business and this could adversely affect our financial condition and results of operations.

We rely on a limited number of third-party contract manufacturers, logistics providers and suppliers, including single or sole source suppliers for certain raw materials, packaging, product components and other supplies. We do not have direct control over the management or business of these third parties, except indirectly through terms negotiated in service or

Table of Contents

supply contracts. As a result, we face substantial risks associated with our reliance on third-party manufacturers, suppliers, and/or logistics providers, including but not limited to the following areas:

•changes to the terms of doing business with these providers or the production capacity they allocate to our products;

•disagreements or the inability to maintain good relationships with these providers, including the failure of these providers to be aligned with our company values;

•inability to successfully implement new manufacturing processes associated with new facilities or new product lines;

•concentration of inventory increasing exposure to risks associated with fire, natural disasters, theft and logistics disruptions to customer order fulfillment;

•financial difficulties experienced by these providers;

•consolidation of third-party packagers, which could reduce competition in the industry and increase our costs for their services or result in the surviving company declining to manufacture or store our products;

•change in ownership of our third-party contract manufacturers which could cause delays or other significant disruptions to our production capacity;

•significant disruptions in the production or transportation of our products due to events having regional or global impacts on economic activity, such as public health emergencies, natural disasters or extreme weather conditions; or

•significant disruptions in the production or transportation of our products due to competition for materials, components, labor or services from third-party vendors.

In addition, if we are unable to contract with third-party manufacturers or suppliers for the quantity and quality levels needed for our business, we could experience disruptions in production and our financial results could be adversely affected. In particular, global health crises, extreme weather events, military conflicts and other macroeconomic factors have resulted in significant supply chain constraints and transportation disruptions at times. Some of the challenges that we have experienced historically include general aerosol-related production capacity constraints and competition for such capacity by other companies who utilize the same third-party manufacturers for their aerosol production. These challenges have periodically resulted in us not being able to meet the demand for our products by customers and end users in certain markets where demand for aerosols has, for certain products, outpaced the available production capacity in those markets. We monitor partnerships with our third-party manufacturers and onboard new third-party manufacturers, if necessary, in order to allow for capacity and flexibility of our supply chain. Onboarding new third-party manufacturers involves inherent risks that can include delays in setting up production, testing and potential rework to ensure production quality, and higher costs. In addition, actions we have taken in the past to increase inventory levels of certain raw materials and finished goods to mitigate challenges within supply chain and increased lead times required by suppliers, have led to higher transportation, storage and distribution costs. It is not possible to estimate the degree of the impact or the costs associated with potential future disruptions within our supply chain and distribution networks as such supply chain issues are being resolved.

Dependence on key customers could adversely affect our business, financial condition and results of operations.

We sell our products through a network of domestic and international mass retail, trade supply and consumer retailers as well as through industrial distributors and suppliers. The retail industry has historically been the subject of consolidation and, as a result, the development of large chain stores has taken place. Today, the retail channel is comprised of several of these large chain stores that capture the bulk of the market share. Since many of our customers have been part of consolidations in the retail industry, these limited customers account for a large percentage of our net sales. Although we expect that a significant portion of our revenues will continue to be derived from this limited number of customers, our largest individual customer contributed to less than 10% of our consolidated net sales in fiscal year 2025. However, changes in the strategies of our largest customers may have an adverse impact on our sales. Such changes in customer strategy may include, but are not limited to: demands for more liberal return rights, a reduction in willingness to transport and store goods of certain hazardous material ratings, a reduction in the number of brands they carry, or a shift in shelf

Table of Contents

space in favor of “private label” or competitors’ products. The loss of, or reduction in, orders or a higher volume of returns from any of our most significant customers could have a material adverse effect on our brand values, business, financial condition and results of operations. Large customers may seek price reductions, price protection, added support, product deliveries within shorter lead times, non-compliance fees or promotional concessions. If we agree to such customer demands and/or requests, it could negatively impact our ability to maintain existing profit margins.

In addition, our business is primarily based upon individual sales orders, and we typically do not enter into long-term contracts with our customers. Accordingly, these customers could reduce their purchasing levels or cease buying products from us at any time and for any reason. We are also subject to changes in customer purchasing patterns or the level of promotional activities. These types of changes may result from changes in the manner in which customers purchase and manage inventory levels, or display and promote products within their stores. Other potential factors such as customer disputes regarding shipments, fees, merchandise condition or related matters may also impact operating results. If we cease doing business with a significant customer or if sales of our products to a significant customer materially decrease, our business, financial condition and results of operations may be harmed.

Malfunctions or implementation issues related to the critical information systems that we use for the daily operations of our business, cyberattacks and data breaches could adversely affect our ability to conduct business.

To conduct our business, we extensively rely on information technology systems, networks and services, many of which are managed, hosted and provided by third-party service providers. There is no guarantee that our security measures will prevent cyberattacks resulting in breaches of our own or our third-party service providers’ databases and systems. Techniques used in these attacks change frequently and may be difficult to detect for periods of time. Although we have policies and procedures in place governing (i) the timely investigation of cybersecurity incidents, (ii) the timely disclosure of any related material nonpublic information resulting from a material cybersecurity incident, and (iii) the safeguarding against insider trading by directors, officers, and other corporate insiders between the period of investigation and the public disclosure of such an incident; cybersecurity incidents themselves, such as the release of sensitive data from our databases and systems, could adversely affect our business, financial condition and results of operations. The increasing number of information technology security threats and the development of more sophisticated cyberattacks, which includes the adoption of emerging technologies such as AI and machine learning, as well as other techniques such as ransomware, pose significant potential risks to the security of our information technology systems and networks, as well as to the confidentiality, availability and integrity of our data. Increased integration of AI into our operations could significantly increase cybersecurity and privacy risks, including the risk of unauthorized or misuse of AI tools. In addition, threat actors may leverage these tools to attack our systems. The continued use of remote work infrastructures also increases cybersecurity risks. These emerging risks could materially increase the costs that we incur to protect against such risks. Although we maintain cyber insurance, our coverage may not be adequate for actual losses incurred, and an insurer may deny coverage of a future claim. There is no certainty that such insurance will continue to be available to us on economically reasonable terms, if at all, in the future.

In addition, system failure, malfunction or loss of data that is housed in our critical information systems or our third-party service providers’ critical information systems could disrupt our ability to ship products to our customers, timely and accurately process transactions and produce key financial reports, including information on our operating results, financial position and cash flows. Our information systems could be damaged or cease to function properly due to a number of other reasons, including catastrophic events and power outages. Although we have business continuity plans in place to address such service interruptions, there is no guarantee that these business continuity plans will provide alternative processes in a timely manner. As a result, we may experience interruptions in our ability to manage our daily operations, which could harm our business, financial condition and results of operations.

We are currently implementing new information systems within our enterprise resource planning framework at certain offices in a phased manner. The first and most significant phase, implementation in the U.S., was completed in fiscal year 2024. We are strategically implementing these new information systems at certain other offices to better align with the U.S. system environment. In addition, the company that owns and supports the legacy systems used at these other offices may not be able to provide the same level of support as that of larger information systems companies. If the company that owns and supports the legacy systems were to cease operations or were unable to provide support for this application prior to the implementation of our new information systems, it could adversely affect our daily operations or our business, financial condition and results of operations. If we encounter difficulties in executing and completing the implementation of these new critical information systems at our other offices, or if the implementation takes longer than intended, we may experience interruptions in our ability to manage our daily operations and report financial results timely and we may

Table of Contents

experience significant incremental costs, which could adversely affect our business, financial condition and results of operations.

Our ability to achieve our environmental, social and governance and sustainability initiatives are subject to emerging risks and the outcomes may not achieve the anticipated benefits or align with new regulations and stakeholders’ expectations.

There has been an increasing focus from regulators and other stakeholders related to environmental, social and governance (“ESG”) matters across all industries in recent years. ESG standard setting and stakeholder expectations continue to evolve. Criteria used to evaluate ESG practices and metrics may change rapidly at any time, which could result in increased expectations from stakeholders and may cause us to undertake costly initiatives to satisfy any new requirements. Non-compliance with such regulations or a failure to address stakeholder expectations may result in cost increases, litigation, fines, penalties, production and sales restrictions, brand or reputational damage, loss of customers, failure to retain and attract talent, lower valuation and investor activism. Any failure or perceived failure, whether or not valid, to pursue and fulfill our ESG initiatives and objectives or to satisfy various ESG reporting standards in a timely manner could negatively impact our financial condition and results of operations.

In 2023, the European Commission’s Corporate Sustainability Reporting Directive (“CSRD”) became effective. The CSRD expands the number of companies required to publicly report ESG-related information and defines the ESG-related information that companies are required to report in accordance with European Sustainability Reporting Standards. While CSRD rules are prescriptive for the types of data to be reported, the standards to quantify and qualify such data are still evolving and uncertain and will impose increased costs on us related to complying with our reporting obligations. In 2023, California enacted Senate Bill (“SB”) 253 and SB 261, which require large businesses to report on greenhouse gas emissions and climate-related financial risks in accordance with the Task Force on Climate-Related Financial Disclosures framework. The increased attention directed towards publicly traded companies surrounding ESG matters includes the release of rules by the SEC requiring registrants to enhance and standardize disclosures related to climate change, but these rules have since been stayed due to litigation. Although the SEC attempted to end its defense of the rules in 2025, the litigation remains unsettled and additional rules could be proposed in the future by the SEC. We expect to be subject to these regulations in the future, which will result in cost increases. Failure to comply with such regulations could negatively impact our financial condition and results of operations.

Government laws and regulations, including environmental laws and regulations, could result in material costs or otherwise adversely affect our financial condition and results of operations.

The manufacturing, chemical composition, packaging, storage, distribution and labeling of our products and the way our business operates must comply with state, federal and international laws and regulations. If we do not comply with such laws and regulations, we could be fined or other actions could be taken against us by the applicable governing body, including a required product recall. Any such regulatory action could adversely affect our financial condition and results of operations. Governments and regulatory agencies may increase regulation, including the adoption of further regulations relating to the transportation, storage or use of certain chemicals, to enhance homeland security or protect the environment, and such increased regulation could negatively impact our ability to obtain raw materials, components and/or finished goods or could result in increased costs.

Some of our products have chemical compositions that are controlled by state, federal and international laws and regulations that are subject to change. There can be no assurance that we will not be required to alter the chemical composition of one or more of our products in a way that will have an adverse effect upon the product’s efficacy, marketability or cost. A delay or other inability on our part to complete product research and development and successfully reformulate our products in response to any such regulatory requirements could have a material adverse effect on our business, financial condition and results of operations.

We are subject to an SEC rule mandated by Section 1502 of the Dodd-Frank Wall Street Reform and Consumer Protection Act that requires management to conduct annual due diligence to determine whether certain minerals and metals, known as “conflict minerals”, are contained in our products and, if so, whether they originate from the Democratic Republic of Congo or adjoining countries. Although we have concluded that our current products do not contain such “conflict minerals” in our annual evaluations to date, if we were to conclude that these materials exist within our products in the future, we may have difficulty verifying the origin of such materials for purposes of disclosures required by the SEC rules.

Table of Contents

We are also subject to laws and regulations that impose environmental controls on our business operations, including, among other things, the discharge of pollutants into the air and water, the handling, use, treatment, storage and clean-up of solid and hazardous wastes and the investigation and remediation of soil and groundwater affected by hazardous substances. Such laws and regulations may otherwise relate to various health and safety matters that impose burdens upon our operations. These laws and regulations also impose strict, retroactive and joint and several liability for the costs of, and damages resulting from, cleaning up current sites, past spills, disposals and other releases of hazardous substances. The environmental laws under which we operate are complicated, may become more stringent and may be applied retroactively. Accordingly, we could be required to incur additional expenditures to remain in or to achieve compliance with environmental laws, which could have a material adverse effect on our business, financial condition or results of operations.

We are also subject to Extended Producer Responsibility (EPR) laws under which we have responsibilities to report on product sold and related packaging weights within certain markets. This results in payments of EPR fees to finance end-of-product waste management and recycling. EPR fees have been in place in EIMEA and Canada for several years and are beginning to be established within certain states in the U.S. in calendar year 2025. A delay or other inability on our part to report accurately or pay timely these fees could have a material adverse effect on our business, financial condition and results of operations.

In addition, certain countries and other jurisdictions in which we operate have data protection and anti-trust laws that impose strict regulations on us. Non-compliance with any of these regulations may result in significant penalties being imposed on us. Many international and local governmental authorities are considering increased legislative and regulatory requirements concerning protection of personal data which may impact us and increase our costs to comply with these requirements in the future.

Additional laws and regulations require that we carefully manage our supply chain for the production, distribution and sale of goods. Our failure to comply with any of these regulations or our inability to adequately predict the way these local regulations are interpreted and applied to our business by the applicable enforcement agencies could have a materially adverse effect on our business, financial condition and results of operations.

Failure to maximize or to successfully assert our intellectual property rights or our infringement on the intellectual property rights of others could impact our competitiveness or otherwise adversely affect our financial condition and results of operations.

We rely on trademark, trade secret protection, patent and copyright laws to protect our intellectual property rights. Although we maintain a global enforcement program to protect our intellectual property rights, there can be no assurance that these intellectual property rights will be maximized or that they can be successfully asserted. If other companies or entities infringe on our intellectual property rights or engage in counterfeiting activities, they may dilute the value of our brands in the marketplace, which could diminish the value that consumers associate with our brands, harm our sales, or divert sales of product that we would ordinarily capture in the absence of infringing or counterfeit products.

We may be unable to obtain and protect our own intellectual property rights or, where appropriate, license intellectual property rights necessary to support new product introductions or product lines dependent upon such licensed rights. These rights, if obtained, could be withdrawn, invalidated, circumvented or challenged and we could incur significant costs in connection with legal actions to defend and preserve our intellectual property rights. In addition, even if such rights are obtained in the U.S., other countries’ laws might not protect intellectual property rights to the same extent as the laws of the U.S., or they may be difficult or costly to enforce. Our failure to protect or successfully assert our intellectual property rights or failure to protect our other proprietary information could make us less competitive, which could have a material adverse effect on our business, financial condition and results of operations.

Trade secret protection, particularly for our most valuable product formulation for the WD-40 Multi-Use Product, requires specific agreements, policies and procedures to ensure the secrecy of information classified as a trade secret. If such agreements, policies and procedures are not effective to maintain the secrecy of our trade secrets or if chemical disclosure regulations do not allow for continued protection of essential elements of our trade secret formulations, the loss of trade secret protection could have a material adverse effect on our business, financial condition or results of operations.

If we are found to have violated trademark, copyright, patent or other intellectual property rights of others, such a finding could result in the need to cease the use of a trademark, trade secret, copyrighted work or patented invention in our business and an obligation to pay a substantial amount for past infringement. It could also be necessary to pay a substantial

Table of Contents

royalty in the future if the holders of such rights are willing to permit us to continue to use the intellectual property rights. Either having to cease use or pay such amounts could make us less competitive and could have a material adverse impact on our business, financial condition and results of operations.

Our operating results and financial performance may not meet expectations, which could adversely affect our stock price.

Our operating results and financial performance, which include sales, net income, earnings per common share, gross margin and cash flows, may not meet expectations. If our assumptions and estimates are incorrect or if we do not achieve all our key goals outlined in our strategic framework, then our actual performance could materially vary from our internal expectations and those of the market. Failure to meet or exceed these expectations could cause the market price of our stock to decline. In addition, the trading market for our common stock is influenced by the research and reports that securities analysts, industry analysts and other third parties publish about us or our business. We have no control over these reports or analysts. If securities or industry analysts adversely change their recommendations regarding our common stock or if any of these analysts cease coverage of us in their reports, our stock price and trading volume could decline. Our operating results and financial performance may be negatively influenced by several factors, many of which are discussed in this Item 1A “Risk Factors”.

In addition, sales volume growth, whether due to acquisitions or organic growth, can place burdens on management resources and financial controls that, in turn, can have a negative impact on our operating results and financial condition. To some extent, we plan our expense levels in anticipation of future revenues. If actual revenues fall short of these expectations, operating results may be adversely affected, such as reduced operating margins or operating profits because actual expense levels that are higher relative to projected revenues.

We may not successfully develop, introduce and/or establish new products and line extensions.

Our future performance and growth depend, in part, on our ability to successfully develop, introduce and/or establish new products as both brand extensions and/or line extensions. There is no certainty that we will achieve those goals. We compete in several product categories where there are frequent introductions of new products and line extensions and such product introductions often require significant expenditure and support. Our ability to understand end user needs and preferences is key to maintaining and improving the competitiveness of our product offerings. The development and introduction of new products, as well as the renovation of current products and product lines, require substantial and effective research, development and marketing expenditure, which we may be unable to recoup if the new or renovated products do not gain widespread market acceptance. There are inherent risks associated with new product development and marketing efforts, including product development or launch delays, product performance issues during development, changing regulatory frameworks that affect the new products in development and the availability of key raw materials included in such products. These inherent risks could result in the failure of new products and product line extensions to achieve anticipated levels of market acceptance, additional costs resulting from failed product introductions and the product not being first to market. As we continue to focus on innovation and renovation of our products, our business, financial condition or results of operations could be materially adversely affected if we are not able to effectively develop and introduce new or renovated products and line or brand extensions.

If we are unable to successfully identify, complete or realize the benefits from strategic business developments, acquisitions, divestitures, joint ventures or investments, our financial results could be materially adversely affected.

We may increase growth through business development activities such as acquisitions, joint ventures, licensing and/or other strategic partnerships. If we are not able to identify, acquire and successfully integrate acquired products or companies or successfully manage joint ventures or other strategic partnerships, we may not be able to maximize these opportunities. The failure to properly manage business development activities because of difficulties in the assimilation of operations and products, the diversion of management’s attention from other business concerns, the loss of key employees or other factors could have a material adverse effect on our business, financial condition and results of operations. In addition, there can be no assurance that our business development activities will be profitable or that they will achieve sales levels, profitability or synergies that justify the investments made.

Future acquisitions, joint ventures or strategic partnerships could also result in the incurrence of debt, potentially dilutive issuances of equity securities, contingent liabilities, amortization expenses related to certain intangible assets, unanticipated regulatory complications and/or increased operating expenses, all of which could materially adversely affect our results of operations and financial condition. In addition, to the extent that the economic benefits associated with any of our business

Table of Contents

development activities not materialize or diminish in the future, we may be required to record impairments to goodwill, intangible assets or other assets associated with such activities, which could also materially adversely affect our business, financial condition and results of operations.

In addition, we may consider divesting businesses or brands that do not meet our strategic objectives or do not meet our growth or profitability targets. For example, we are pursuing the sale of certain of our homecare and cleaning product brands. We may not be able to complete desired divestitures or close divestiture transactions on terms favorable to us. If we do complete such desired divestitures, gains or losses on the sales of, or lost operating income from, those businesses or brands may harm our profitability and margins. We may not be able to effectively deploy the proceeds from a divestiture in a manner that is accretive to our earnings. If we are unable to identify and execute on suitable investment opportunities, or if the investments we make do not perform as expected, our financial condition and results of operations could be adversely affected. Additionally, the failure to effectively reinvest such proceeds could result in lower returns on investment and diminished stockholder value.

Changes in marketing distributor relationships that are not managed successfully by us could result in a disruption in the affected markets.

We distribute our products throughout the world in one of two ways: the direct distribution model, in which products are sold directly by us to wholesalers and retailers in the U.S., Canada, Mexico, Brazil, Australia, China, the U.K. and a number of other countries, including those throughout Europe; and the marketing distributor model, in which products are sold to marketing distributors who in turn sell to wholesalers and retailers. The marketing distributor model is generally used in countries where we do not have direct Company-owned operations. Instead, we work with local companies who perform the sales, marketing and distribution functions. We invest time and resources into these relationships. Should our relationship with new or existing marketing distributors be unsuccessful, our sales within such a marketing distributor’s territory could be adversely impacted until such time as a suitable replacement can be found and our key marketing strategies are implemented. There is a risk that changes in such marketing distributor relationships, including a change in key marketing distributor personnel or a transition to the direct distribution model, if not managed successfully, could result in a disruption in the affected markets and that such disruption could have a material adverse effect on our business, financial condition and results of operations. Additionally, in some countries, local laws may require substantial payments to terminate existing marketing distributor relationships, which could also have a material adverse effect on our business, financial condition and results of operations.

Product liability claims and other litigation and/or regulatory action could adversely affect our sales and operating results.

The use of our products may expose us to liability claims resulting from such use and potential enforcement actions, including the risk of recall. Claims could be based on allegations that, among other things, our products are improperly labeled or that statements we make on our labels are not accurate, contain contaminants, provide inadequate instructions regarding their use or inadequate warnings concerning their use or interactions with other substances. Product liability claims could result in negative publicity that could harm our sales and operating results. We maintain product liability insurance to protect us from loss attributable to product liability claims, but the extent of such loss could exceed available limits of insurance or could arise out of circumstances under which such insurance coverage is unavailable. Other business activities may also expose us to litigation risks, including risks that may not be covered by insurance such as contract disputes. If successful claims are asserted by regulatory agencies or third parties against us for non-compliance or uninsured liabilities or liabilities more than applicable limits of insurance coverage, our business, financial condition and results of operations may be adversely affected. If one of our products were determined to be noncompliant or mislabeled, we could be required to recall the product, which could result in significant expenses, adverse publicity and loss of revenues. Even if we are successful in defending against such claims, litigation could result in substantial cost and be a distraction to our management and employees.

Additionally, our products may be associated with competitor products or other products in the same category that may be alleged to have caused harm to consumers. As a result of this association, we may be named in unwarranted legal actions. The potential costs to defend such claims may materially affect our business, financial condition and results of operations.

Resolution of income tax matters may impact our financial condition and results of operations.

Significant judgment is required in determining our effective income tax rate and in evaluating tax positions, particularly those related to uncertain tax positions. We provide liabilities for uncertain tax positions when such tax positions do not

Table of Contents

meet the recognition thresholds or measurement requirements prescribed by the specific accounting standards for uncertain tax positions. Changes in uncertain tax positions or other adjustments resulting from tax audits and settlements with taxing authorities, including related interest and penalties, impact our effective tax rate. When tax matters arise, a number of years may elapse before such matters are audited and resolved, or the statute of limitations expires resulting in the release of the liability. Resolution of such matters or the expiration of the statute of limitations would be recognized as a reduction to our effective tax rate in the year of resolution. Any resolution of a tax matter may require the adjustment of tax assets or tax liabilities or the use of cash in the year of resolution. For additional information on such matters, see Part IV – Item 15, “Exhibits, Financial Statement Schedules” Note 15 — Income Taxes, in this report.

Changes in U.S. or international tax law that occur in the locations where we operate can also materially affect future financial results or operations. For example, we have significant operations in Europe that are subject to income tax rates and laws in multiple jurisdictions and a significant portion of our European income is subject to taxation in the U.K. because our European subsidiary is headquartered in the U.K. In June of 2021, an Act of Parliament received Royal Assent, changing the U.K. corporate tax rate from 19% to 25% effective on April 1, 2023, resulting in an increase in our effective tax rate.

We cannot predict how subsequent changes in the Tax Act, the Inflation Reduction Act, regulations, or other guidance issued under each, including conforming or non-conforming state tax rules, might affect our business, financial condition and results of operations. In addition, there can be no assurance that U.S. tax laws, including the corporate income tax rate, will not undergo significant additional changes in the future.

Goodwill and intangible assets are subject to impairment risk.

We assess the potential impairment of our goodwill during the second quarter of each fiscal year and when events or changes in circumstances indicate that an impairment condition may exist. We also assess our definite-lived intangible assets for potential impairment when events and circumstances indicate that the carrying amount of the asset may not be recoverable or its estimated remaining useful life may no longer be appropriate. Indicators such as underperformance relative to historical or projected future operating results, changes in our strategy for our overall business or use of acquired assets, unexpected negative industry or economic trends, decline in our stock price for a sustained period, decreased market capitalization relative to net book values, unanticipated technological change or competitive activities, loss of key distribution, change in consumer demand, loss of key personnel and acts by governments and courts may signal that an asset has become impaired.

The assessment for possible impairment of our goodwill and intangible assets involves judgments on several significant estimates and assumptions, including macroeconomic conditions, overall category growth rates, sales growth rates, cost containment and margin expansion and expense levels for advertising and promotions and general overhead, all of which are developed from a market participant standpoint. We may be required to record a significant charge in our consolidated financial statements during the period in which any impairment of our goodwill or intangible assets is identified, which could materially adversely affect our financial condition and results of operations. Strategic divestitures of certain businesses or brands could negatively impact our profitability as a result of a reduction in sales and operating income, decrease our cash flows, or cause us to recognize impairment charges. Changes in management estimates and assumptions as they relate to valuation of goodwill and intangible assets could affect our financial condition or results of operations in the future. For additional information, see Part IV – Item 15, “Exhibits, Financial Statement Schedules” Note 7 — Goodwill and Other Intangible Assets, in this report.

We may not have sufficient cash to service our indebtedness or to pay cash dividends.

Our debt consists of fixed rate senior notes and a revolving credit facility. We use income from operations to make interest and principal payments on our debt. Borrowings under our credit facility are at variable rates of interest and expose us to interest rate risk. If interest rates increase, our debt service obligations on the variable rate indebtedness will increase even if the amount borrowed remains the same, and our net income and cash flows, including cash available for servicing our indebtedness, will decrease. Our borrowing agreements include covenants to maintain certain financial ratios and to comply with other financial terms and conditions. Although we have historically paid out a large part of our earnings to stockholders in quarterly cash dividends, we may not have sufficient cash to do so in the future.

We may incur substantial debt in the future for general business and development activities. In addition, we may continue to use available cash balances to execute share repurchases under approved share buy-back plans. To the extent that we are required to seek additional financing to support certain of these activities, such financing may not be available in sufficient

amounts or on terms acceptable to us, if at all. If we are unable to obtain such financing or to service our existing or future debt with our operating income, or if available cash balances are affected by future business performance, unstable global economic conditions, liquidity, capital needs, alternative investment opportunities or debt covenants, we could be required to reduce, suspend or eliminate our dividend payments to our stockholders. We may also reduce or suspend share repurchases depending on available or projected cash balances.

Cybersecurity Risk Management and Strategy

Management is responsible for cybersecurity risk management, which is part of our enterprise risk management and business continuity processes. We regularly evaluate our cybersecurity risk profile as well as the status and activities of our cybersecurity program, which aligns to the industry-recognized Center for Internet Security or CIS framework. We employ a defense-in-depth strategy which involves multiple layers of security controls to help prevent and detect possible risks and employ measures to protect our systems from business disruption. Our cybersecurity program includes tools and activities to prevent, detect, and analyze current and emerging cybersecurity threats, as well as plans and strategies to address threats and incidents. We also engage with third-party service providers, who possess expertise in information technology and cybersecurity, to aid in the design, implementation, and management of our cybersecurity infrastructure and protocols.

As part of our continuing education, employees are required to participate in cybersecurity awareness training at the commencement of their employment and annually thereafter. We reinforce this training with monthly internal phishing tests and cybersecurity newsletters to educate our employees on the latest cybersecurity threats and the most effective preventative measures.

As of the date of this Annual Report, we have not identified any cybersecurity threats that have had, or are likely to have, a material impact on our operations, including our business strategy, financial results, or financial condition. For more information on the risks associated with cybersecurity, refer to the “Risk Factors” section contained in Item 1A of this Form 10-K.

Cybersecurity Governance

Management is responsible for implementing our cybersecurity program. Our Chief Financial Officer works with our Vice President of Global Information & Technology (“IT”) and regional IT members to lead our enterprise-wide information security program and manage our Cybersecurity Incident Response Plan. With over 30 years of experience in technology and information systems leadership our Vice President, Global IT oversees a highly experienced professional team within its global network. These teams work closely with internal stakeholders to develop, implement, and maintain a comprehensive security strategy that protects our enterprise and supports our business objectives. They also coordinate incident response efforts and proactively address emerging security threats. The recommendations of the management team are consulted when updating our information security policies, procedures, and standards.

The Audit Committee oversees our cybersecurity risk and mitigation strategies. This committee is regularly briefed by management on the status and effectiveness of our cybersecurity initiatives, including policies and actions taken to monitor, identify, evaluate, mitigate, and report significant risks. The Audit Committee has specific training in overseeing cybersecurity risks, including a member who has earned Carnegie Mellon’s CERT (Certificate in Cyber-Risk Oversight) and another with a certificate earned over cybersecurity risk. In addition, the Audit Committee receives periodic briefings from external experts in the area and regularly reports its oversight activities to the full board.

Overview

The Company

WD-40 Company, based in San Diego, California, is a global marketing organization dedicated to creating positive lasting memories by developing and selling products that solve problems in workshops, factories and homes around the world. We own a wide range of well-known brands that include maintenance products and homecare and cleaning products: WD-40® Multi-Use Product, WD-40 Specialist®, 3-IN-ONE®, GT85®, X-14®, 2000 Flushes®, Carpet Fresh®, no vac®, Spot Shot®, Lava® and Solvol®.

Our products are sold in various locations around the world. Maintenance products are sold worldwide in markets throughout North, Central and South America, Asia, Australia, Europe, India, the Middle East and Africa. Homecare and cleaning products are sold primarily in North America, the United Kingdom (“U.K.”) and Australia. During the fiscal year 2025, our homecare and cleaning business in EIMEA was sold and we have reclassified our homecare and cleaning business in Americas to held for sale. Our homecare and cleaning business in the Asia-Pacific segment continues to be held for use. We sell our products primarily through hardware stores, automotive parts outlets, industrial distributors and suppliers, mass retail and home center stores, value retailers, grocery stores, online retailers, warehouse club stores, farm supply, sport retailers, and independent bike dealers.

Highlights

The following summarizes the financial and operational highlights for our business during the fiscal year ended August 31, 2025:

•Consolidated net sales increased $29.4 million, or 5%, for fiscal year 2025 compared to the prior fiscal year. Increases in sales volume favorably impacted net sales by approximately $25.2 million from period to period. Increases in the average selling price of our products positively impacted net sales by approximately $5.6 million from period to period, primarily due to sales price increases implemented in certain regions during the prior fiscal year. Changes to net sales attributable to volumes and average selling price of our products are impacted by differences in sales mix related to products, markets and distribution channels from period to period. In addition, changes in foreign currency exchange rates from period to period had a unfavorable impact of $1.4 million on consolidated net sales for the fiscal year 2025. Gross profit as a percentage of net sales increased to 55.1% for fiscal year 2025 compared to 53.4% for the prior fiscal year.

•Consolidated net income increased $21.4 million, or 31%, for fiscal year 2025 compared to the corresponding period of the prior fiscal year. Changes in foreign currency exchange rates from period to period had an insignificant effect on consolidated net income for fiscal year 2025.

•Diluted earnings per common share for fiscal year 2025 were $6.69 versus $5.11 in the prior fiscal year. During the second quarter of fiscal year 2025, we released an uncertain tax position that generated a favorable income tax adjustment. Excluding this one-time benefit, on a non-GAAP basis, adjusted diluted EPS was $5.82.

•During the fourth quarter of fiscal year 2025, we completed the sale of the Company’s business pertaining to homecare and cleaning products that are sold in EIMEA.

•During the fiscal year ended August 31, 2025, we returned approximately $62.6 million to our stockholders through share repurchases and dividends.

Americas Sales – Fiscal Year Ended – August 31, 2025 Compared to August 31, 2024

Net sales in the Americas segment increased from period to period, highlighted by the following:

•WD-40 Multi-Use Product sales increased $8.0 million, or 4%, primarily due to increases in Latin America and U.S. of $6.2 million and $2.4 million, respectively. Sales in Brazil increased $6.7 million primarily due to operating under a direct model for the full fiscal year. In the third quarter of fiscal year 2024, we acquired a Brazilian distributor and shifted from an indirect distribution model to a direct model. In addition, sales in other Latin American markets increased $1.0 million due to improved economic conditions in certain regions as well as a higher level of promotional activities. Sales in U.S. increased primarily due to a higher level of promotional programs. These increases in Latin America and U.S. were partially offset by lower sales in Mexico of $2.5 million primarily due to unfavorable changes in foreign currency exchange rates.

•WD-40 Specialist sales increased $2.0 million, or 6%, primarily due to increases in the U.S. due to new distribution and increased demand in mass retail and home center stores as well as online retailers.

•Other maintenance product sales remained relatively constant from period to period.

•Homecare and cleaning product sales decreased $1.1 million, or 7%, primarily due to changes in distribution as well as reduced demand in the U.S. as a result of a lower level of advertising and promotional activities associated with these brands, as we focus on increasing sales of maintenance products in support of our four-by-four strategic framework.

For the Americas segment, 72% of sales came from the U.S., and 28% of sales came from Canada and Latin America combined for the fiscal year ended August 31, 2025 compared to the prior fiscal year when 73% of sales came from the U.S., and 27% of sales came from Canada and Latin America combined.

The regions in the EIMEA segment where we sell through local distributors include the Middle East, Africa, India, Eastern and Northern Europe.

EIMEA Sales – Fiscal Year Ended – August 31, 2025 Compared to August 31, 2024

Net sales increased in the EIMEA segment from period to period, highlighted by the following:

•WD-40 Multi-Use Product sales increased $13.2 million, or 8%, primarily due to higher sales volume across nearly all regions. Sales in direct markets increased significantly in France, Iberia, Benelux, and Italy which were up $3.3 million, $2.0 million, $2.0 million, and $1.7 million, respectively. Sales to our marketing distributors in various regions, increased $1.5 million, most predominately in areas such as India, Croatia, and Romania, primarily due to increased distribution, higher levels of demand and timing of customer orders. Most regions in EIMEA have experienced continued increases in sales volumes after a temporary reduction in demand from customer reactions to price increases we implemented during fiscal year 2023. While most of this volume recovery was experienced in fiscal year 2024 after customers adjusted to those price increases, this volume recovery has continued into fiscal year 2025 and has resulted in higher sales levels from period to period.

•WD-40 Specialist and other maintenance product sales increased $4.8 million, or 15%, and $0.2 million, or 2%, respectively, primarily due to the increased demand and new distribution in our direct markets associated with

Table of Contents

premiumization efforts in support of our strategic framework. Other contributing factors include increased promotional activities in many regions of our direct markets such as DACH and France.

•Homecare and cleaning product sales decreased $2.8 million, or 31%, primarily due to reduced demand in the U.K. as a result of a lower level of advertising and promotional activities associated with these brands as we focus on increasing sales of maintenance products in support of our four-by-four strategic framework.

Net sales in the Asia-Pacific segment increased from period to period, highlighted by the following:

•WD-40 Multi-Use Product sales increased $3.8 million, or 6%, primarily due to sales increases in China and Asia distributor markets of $2.1 million and $1.1 million, respectively. Sales in China increased due to an increased level of marketing and promotional activities coupled with an expansion of the distribution network in certain regions. Sales in Asia distributor markets increased due to higher sales volume from successful promotional programs and marketing activities.

•WD-40 Specialist sales increased $1.2 million, or 12%, primarily due to increased sales volumes in China and Asia distributor markets as a result of successful promotional programs and marketing activities.

•Homecare and cleaning product sales increased $0.4 million or 4%, primarily due to increased sales volume as a result of successful relaunch of the Solvol soap bar in Australia. Our homecare and cleaning businesses in the Asia-Pacific segment are not held for sale.

Gross Profit

The following general information is important when assessing fluctuations in our gross margin:

•There is often a delay before changes in costs of raw materials, such as specialty chemicals used in the formulation of our products, impact cost of products sold due to production and inventory life cycles. Such delays increase with higher production and inventory levels.

•In general, the timing of advertising, promotional and other discounts may cause fluctuations in gross margin from period to period. Advertising, promotional and other discounts that are given to our customers are recorded as a reduction to sales, whereas advertising and sales promotional costs associated with promotional activities that we pay to third parties are recorded as advertising and sales promotion expenses.

•In the EIMEA segment, the cost of our products sold are generated in the Pound Sterling and Euro. The strengthening or weakening of the Pound Sterling and Euro against the U.S. Dollar may result in foreign currency related changes to the gross margin percentage in the EIMEA segment from period to period.

•Our gross profit and gross margin may not be comparable to those of other consumer product companies, since some of these companies include all costs related to distribution of their products in cost of products sold, whereas we exclude the portion associated with amounts paid to third parties for shipment to our customers from our distribution centers and contract manufacturers and include these costs in selling, general and administrative expenses. These costs totaled $18.2 million and $17.3 million for the fiscal years ended August 31, 2025 and 2024, respectively.

The following table summarizes gross margin and gross profit (in thousands, except percentages):

(1)Basis points (“bps”) change in gross margin.

Gross Margin – Fiscal Year Ended – August 31, 2025 Compared to August 31, 2024

Gross margin increased 170 bps primarily due to the following favorable (unfavorable) impacts:


Favorable						Explanations
80 bps						Lower costs of specialty chemicals used in the formulation of our products
60 bps						Lower costs of aerosol cans
50 bps						Increases in average selling prices
(50) bps						Higher warehousing, distribution and freight costs, primarily in the Americas segment

During the first quarter of fiscal year 2025, we reclassified certain assets of our homecare and cleaning product businesses in the Americas and EIMEA segments to held for sale. Gross margin excluding these products would have been 0.5% higher during the fiscal year ended August 31, 2025.

Table of Contents

SG&A Expenses – Fiscal Year Ended – August 31, 2025 Compared to August 31, 2024

The increase in SG&A expenses was primarily due to increases in employee-related costs of $10.4 million primarily due to higher accrued incentive compensation, annual compensation increases, higher stock-based compensation expense and higher headcount. These higher employee-related costs include additional headcount to support various sales growth initiatives identified within our strategic framework and headcount related to the enhancement of our information systems. Travel and meeting expenses increased $1.3 million as a result of additional travel related to geographic expansion and other initiatives aligned with our strategic framework. Professional services fees increased SG&A by $1.2 million primarily due to increases in the EIMEA segment in support of various strategic initiatives. Freight expense increased $0.8 million primarily in the Americas segment, due to higher sales volumes that resulted in higher outbound freight costs. Other miscellaneous SG&A expenses increased due to higher sales commission expense in Brazil of $0.7 million, credit loss adjustments in the U.S. of $0.5 million, and amortization costs associated with cloud computing implementation of $0.5 million, from period to period.

We continued our research and development investment, the majority of which is associated with our maintenance products, including efforts focused on sustainability as well as our focus on innovation and renovation of our products. Research and development costs for the fiscal years ended August 31, 2025 and 2024 were $8.7 million and $8.0 million, respectively. The increase from period to period was partially due to a higher level of research and development activity associated with our sustainability initiatives. Our research and development team engages in consumer research, environmental and sustainability initiatives, product development, product improvements and testing activities. This team leverages its development capabilities by collaborating with a network of outside resources including our current and prospective third-party contract manufacturers. The level and types of expenses incurred within research and development can vary from period to period depending upon the types of activities being performed.

A&P Expenses – Fiscal Year Ended – August 31, 2025 Compared to August 31, 2024

The increase in A&P expenses was primarily due to a higher level of promotional programs and marketing support, particularly in certain countries in the EIMEA segment as well as U.S. and China.

Total promotional costs recorded as a reduction to sales were $34.3 million and $32.7 million for the fiscal years ended August 31, 2025 and 2024, respectively. Therefore, our total expenditure on A&P activities totaled $71.7 million and $66.6 million for the fiscal years ended August 31, 2025 and 2024, respectively.

Americas

Americas Operating Income – Fiscal Year Ended – August 31, 2025 Compared to August 31, 2024

Income from operations for the Americas remained relatively constant year over year. In the Americas, a $8.7 million increase in sales and a higher gross margin was mostly offset by higher operating expenses of $7.7 million. Gross margin for the Americas segment increased from 50.9% to 52.1% primarily due to decreases in the costs of petroleum-based specialty chemicals, increases in average selling prices and a lower level of discounts that we gave to our customers. These favorable impacts were partially offset by higher warehousing, distribution and freight costs increases as well as increases to miscellaneous other input costs. Operating expenses increased $7.7 million primarily due to higher employee-related costs as a result of increased headcount, higher accrued incentive compensation and annual compensation increases. In addition, operating expenses increased due to a higher level of A&P expenses, higher outbound freight costs due to increased sales and an increase in provision for credit losses from period to period. Operating income as a percentage of net sales decreased from 23.1% to 22.5% period over period.

EIMEA

EIMEA Operating Income – Fiscal Year Ended – August 31, 2025 Compared to August 31, 2024

Income from operations for the EIMEA segment increased to $52.3 million, up $5.5 million, or 12%, primarily due to a $15.4 million increase in sales and a higher gross margin, which was partially offset by higher operating expenses. Gross margin for the EIMEA segment increased from 54.7% to 57.3% primarily due to the favorable impact of increases in average selling price and decreases in the cost of aerosol cans and other input costs. Operating expenses increased $8.9 million primarily due to higher employee-related costs as a result of annual compensation increases and increased headcount. In addition, operating expenses increased due to a higher level of professional service costs and travel and meeting expenses in support of our strategic framework. Operating income as a percentage of net sales increased from 21.2% to 22.1% period over period.

Asia-Pacific

Asia-Pacific Operating Income – Fiscal Year Ended – August 31, 2025 Compared to August 31, 2024

Income from operations for the Asia-Pacific segment increased to $30.8 million, up $1.1 million, or 4%, primarily due to a $5.3 million increase in sales and a slightly higher gross margin, partially offset by an increase in operating expenses. Gross margin for the Asia-Pacific segment increased slightly from 58.0% to 58.7%. Operating expenses increased $2.6 million from period to period primarily due to higher employee-related costs. In addition, operating expenses increased as a result of a higher level of A&P expenses, professional service costs and travel and meeting expenses. Operating income as a percentage of net sales decreased from 33.9% to 33.1% period over period.

Non-Operating Items

The following table summarizes non-operating income and expenses for our consolidated operations (in thousands):


	Fiscal Year Ended August 31,
	2025		2024		Change
Interest income	$	517	$	474	$	43
Interest expense	$	3,441	$	4,287	$	(846)

Provision for income taxes	$	10,632	$	21,864	$	(11,232)

Interest Income

Interest income was not significant for both the fiscal years ended August 31, 2025 and 2024.

Interest Expense

Interest expense decreased $0.8 million primarily due to a decrease in weighted average outstanding balance on our revolving credit facility slightly offset by higher interest rates related to draws on this credit facility.

Other Income (Expense), Net

Other income (expense), net changed by $1.8 million from period to period which was primarily due to net foreign currency losses during fiscal year 2024 as compared to net foreign currency exchange gains in fiscal year 2025 due to fluctuations in the foreign currency exchange rates for both the Euro and the U.S. Dollar against the Pound Sterling.

Provision for Income Taxes

The provision for income taxes was 10.5% and 23.9% of income before income taxes for the fiscal years ended August 31, 2025 and 2024, respectively. Descriptions of impacts on our effective income tax rate are incorporated by reference to Part IV—Item 15, “Exhibits, Financial Statement Schedules” Note 15 — Income Taxes, included in this report.

Net Income

Net income was $91.0 million, or $6.69 per common share on a fully diluted basis, for fiscal year 2025 compared to $69.6 million, or $5.11 per common share on a fully diluted basis, for the prior fiscal year.

Performance Measures and Non-GAAP Reconciliations

In managing our business operations and assessing our financial performance, we supplement the information provided by our financial statements with certain non-GAAP performance measures. These performance measures are part of our current 55/30/25 business model, which includes gross margin, cost of doing business, and Adjusted EBITDA (defined below), the latter two of which are non-GAAP performance measures. Cost of doing business is defined as total operating expenses less amortization of definite-lived intangible assets, impairment charges related to intangible assets, amortization of implementation costs associated with cloud computing arrangements (“cloud computing amortization”) and depreciation in operating departments. Adjusted EBITDA is defined as net income before interest, income taxes, depreciation, amortization of definite-lived intangible assets, and cloud computing amortization.

We target our gross margin to be 55% of net sales, our cost of doing business to be 30% of net sales, and our Adjusted EBITDA to be 25% of net sales. Results for these performance measures may vary from period to period depending on

Table of Contents

various factors, including economic conditions such as the inflationary environment we have experienced in the last several fiscal years, and our level of investment in activities for the future such as those related to quality assurance, regulatory compliance, information technology, sustainability, and intellectual property protection in order to safeguard our WD-40 brand. Our targets for gross margin, cost of doing business and Adjusted EBITDA are long-term in nature. We expect to make progress towards our cost of doing business and Adjusted EBITDA targets over time. Progression towards our cost of doing business and Adjusted EBITDA targets may be challenged as we continue to divest certain of our homecare and cleaning product businesses, due to the low level of operating expenses associated with these businesses. Despite these potential challenges, we intend to focus our resources and proceeds from the sale of those brands on growing our higher growth and higher gross margin core business.

The following table summarizes the results of these performance measures:


	Fiscal Year Ended August 31,
	2025		2024		2023
Gross margin – GAAP	55	%	53	%	51	%
Cost of doing business as a percentage of net sales – non-GAAP	37	%	36	%	33	%
Adjusted EBITDA as a percentage of net sales – non-GAAP (1)	18	%	18	%	18	%

(1)Percentages may not aggregate to Adjusted EBITDA percentage due to rounding and because amounts recorded in other income (expense), net on our consolidated statements of operations are not included as an adjustment to earnings in the Adjusted EBITDA calculation.

We use the performance measures above to establish financial goals and to gain an understanding of our comparative performance from period to period. We believe that these measures provide our stockholders with additional insights into how we run our business. We believe these measures also provide investors with additional financial information that should be considered when assessing our underlying business performance and trends. These non-GAAP financial measures are supplemental in nature and should not be considered in isolation or as alternatives to net income, income from operations or other financial information prepared in accordance with GAAP as indicators of our performance or operations. The use of any non-GAAP measure may produce results that vary from the GAAP measure and may not be comparable to a similarly defined non-GAAP measure used by other companies. Reconciliations of these non-GAAP financial measures to our financial statements as prepared in accordance with GAAP are as follows:

Adjusted EPS

During the second quarter of fiscal year 2025 we released a previously unrecognized tax benefit associated with the Tax Cuts and Jobs Act of 2017 mandatory “toll tax” on unremitted foreign earnings. This item is infrequent in nature and not reflective of the underlying operational results of our business. We have included a non-GAAP measure of Adjusted EPS which is defined as diluted EPS less benefits associated with this toll tax on unremitted earnings.

Liquidity and Capital Resources

Overview

Our financial condition and liquidity remain strong. Although there continues to be uncertainty related to adverse global economic conditions, volatility in financial markets, the current inflationary environment and their impacts on our future results, we believe our efficient business model positions us to manage our business through such situations. We continue to manage all aspects of our business including, but not limited to, monitoring our liquidity, the financial health of our customers, suppliers and other third-party relationships, implementing gross margin enhancement strategies and developing new opportunities for growth.

Our principal sources of liquidity are cash generated from operations and cash currently available from our existing unsecured revolving credit facility under the Credit Agreement with Bank of America, N.A. We use the revolving credit facility primarily for our general working capital needs. We also hold borrowings under the Note Agreement. See Note 10 — Debt, incorporated by reference to Part IV—Item 15, “Exhibits, Financial Statement Schedules” for additional information on these agreements.

We have historically held a balance of outstanding draws on our line of credit in either U.S. Dollars in the Americas segment or in Euros and Pounds Sterling in the EIMEA segment. Euro and Pound Sterling denominated draws fluctuate in U.S. Dollars from period to period due to changes in foreign currency exchange rates. We regularly convert many of our draws on our line of credit to new draws with new maturity dates and interest rates. We have the ability to refinance any draws under the line of credit with successive short-term borrowings through the April 30, 2029 maturity date of the Credit

Table of Contents

Agreement. Outstanding draws for which we have both the ability and intent to refinance with successive short-term borrowings for a period of at least twelve months are classified as long-term. As of August 31, 2025, $21.0 million of this facility was classified as long-term and was entirely denominated in Euros. In the United States, we held $66.0 million in fixed rate long-term borrowings as of August 31, 2025, consisting of senior notes under our Note Agreement. We paid $0.8 million in principal payments on our Series A Notes during fiscal year 2025. There were no other letters of credit outstanding or restrictions on the amount available on our line of credit or notes. Per the terms of both the Note Agreement and the Credit Agreement, our consolidated leverage ratio cannot be greater than three and a half to one and our consolidated interest coverage ratio cannot be less than three to one. See Note 10 — Debt, incorporated by reference to Part IV—Item 15, “Exhibits, Financial Statement Schedules” for additional information on these financial covenants. At August 31, 2025, we were in compliance with all material debt covenants. We continue to monitor our compliance with all debt covenants and, at the present time, we believe that the likelihood of being unable to satisfy all material covenants is remote. At August 31, 2025, we had a total of $58.1 million in cash and cash equivalents. We do not foresee any ongoing issues with repaying our borrowings and we closely monitor the use of this credit facility.

We believe that our future cash from domestic and international operations, together with our access to funds available under our unsecured revolving credit facility, will provide adequate resources to fund short-term and long-term operating requirements, capital expenditures, dividend payments, acquisitions, new business development activities and share repurchases.

On June 16, 2025, the Board approved the extension of the expiration date to August 31, 2026 for the 2023 Repurchase Plan, which became effective on September 1, 2023 and was set to expire August 31, 2025. We are authorized to acquire up to $50.0 million of our outstanding shares through August 31, 2026, of which $29.6 million remained available for the repurchase of shares of common stock as of August 31, 2025.

Cash Flows

The following table summarizes our cash flows by category for the periods presented (in thousands):


	Fiscal Year Ended August 31,
	2025		2024		2023
Net cash provided by operating activities	$	87,925	$	92,034	$	98,391
Net cash used in investing activities	(2,388)		(9,735)		(6,216)
Net cash used in financing activities	(74,116)		(83,936)		(85,048)
Effect of exchange rate changes on cash and cash equivalents	10		193		3,173
Net increase (decrease) in cash and cash equivalents	$	11,431	$	(1,444)	$	10,300

Operating Activities

Net cash provided by operating activities decreased $4.1 million to $87.9 million for fiscal year 2025. Cash flows from operating activities depend heavily on operating performance and changes in working capital. Our primary source of operating cash flows for fiscal year ended August 31, 2025 was net income of $91.0 million, which increased $21.4 million from period to period, primarily due to the release of the uncertain tax position in the second quarter of fiscal year 2025 that resulted in a net benefit of $11.9 million, as discussed in Note 15 — Income Taxes, incorporated by reference to Part IV—Item 15, “Exhibits, Financial Statement Schedules” to the consolidated financial statements.

Changes in our working capital decreased net cash provided by operating activities by $10.5 million for the fiscal year 2025, compared to a $4.6 million increase in the prior fiscal year. This unfavorable $15.1 million net change in working capital was primarily due to changes in inventory, other assets, and accrued payroll. Increases in inventory balances decreased net cash provided by operating activities by $11.6 million, most significantly in the EIMEA segment primarily due to the onboarding of new packagers to support new regional expansion and distribution. As a result of this expansion, we are carrying higher inventory balances than in prior periods in order to support anticipated demand. Changes in other asset balances decreased working capital by $9.1 million, primarily due to a $4.1 million increase in taxes receivable from timing of tax payments as well as a $3.2 million increase in assets related to cloud computing arrangements. In addition, net cash provided by operating activities decreased by $7.0 million due to significantly lower accruals for earned incentive compensation in fiscal year 2025 as compared to fiscal year 2024.

Table of Contents

These unfavorable changes in working capital were partially offset by favorable changes in trade and other accounts receivable balances of $15.8 million primarily due to the timing of collection of payments from customers in the United States.

Investing Activities

Net cash used in investing activities decreased $7.3 million to $2.4 million for fiscal year 2025 primarily due to the prior year acquisition of a Brazilian distributor for $6.2 million as we shifted from an indirect distribution model to a direct model in the fiscal year 2024. In addition, proceeds of $1.7 million from the sale of our homecare and cleaning product business in the EIMEA segment in fiscal year 2025 decreased net cash used in investing activities.

Financing Activities

Net cash used in financing activities decreased $9.8 million to $74.1 million for fiscal year 2025. This decrease is primarily due to lower net repayments on our revolving credit facility of $17.5 million. This decrease in net cash used in financing activity was partially offset by an increase of $4.2 million in treasury stock purchases and an increase in dividends paid to our stockholders of $3.1 million.

Effect of Exchange Rate Changes

All of our foreign subsidiaries currently operate in currencies other than the U.S. Dollar and a significant portion of our consolidated cash balance is denominated in these foreign functional currencies, particularly at our U.K. subsidiary. As a result, our cash and cash equivalents balances are subject to the effects of the fluctuations in these functional currencies against the U.S. Dollar at the end of each reporting period. The net effect of exchange rate changes on cash and cash equivalents, when expressed in U.S. Dollar terms was not significant in both fiscal years 2025 and 2024, and was an increase in cash of $3.2 million in fiscal year 2023. These changes were primarily due to fluctuations in various foreign currency exchange rates from period to period, but the majority is related to the fluctuations in the Euro against the U.S. Dollar.

Cash Flows

Fiscal Year Ended August 31, 2024 Compared to Fiscal Year Ended August 31, 2023

For discussion related to changes in the consolidated statements of cash flows for fiscal year 2024 compared to fiscal year 2023, refer to Part II—Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations included in our Annual Report on Form 10-K for the fiscal year ended August 31, 2024, which was filed with the SEC on October 21, 2024.

Share Repurchase Plans

The information required by this item is incorporated by reference to Part IV—Item 15, “Exhibits, Financial Statement Schedules” Note 11 — Share Repurchase Plan, included in this report.

Dividends

We have historically paid regular quarterly cash dividends on our common stock. On December 11, 2024, our Board approved a 7% increase in the regular quarterly cash dividend, increasing it from $0.88 per share to $0.94 per share. On October 9, 2025, our Board declared a cash dividend of $0.94 per share payable on October 31, 2025 to stockholders of record at the close of business on October 20, 2025. Our ability to pay dividends could be affected by future business performance, liquidity, capital needs, alternative investment opportunities and loan covenants.

Contractual Obligations

We hold borrowings under our Note Purchase and Private Shelf Agreement with fixed repayment requirements and under a Revolving Credit Facility that has variable underlying interest rates. For additional details on these borrowings, including ability and intent assessment on our credit facility agreement with Bank of America, N.A., refer to the information set forth in Part IV—Item 15, “Exhibits, Financial Statement Schedules”, Note 10 — Debt.

Table of Contents

We have ongoing relationships with various suppliers (contract manufacturers) that manufacture the Company’s products, and third-party distribution centers that warehouse and ship the Company’s products to customers as well as adhere to certain minimum purchase obligations with these contract manufacturers. For additional details on these purchase commitments, refer to the information set forth in Part IV—Item 15, “Exhibits, Financial Statement Schedules” Note 14 — Commitments and Contingencies.

We have also recorded a liability for uncertain tax positions. For details on our uncertain tax positions, refer to the information set forth in Part IV—Item 15, “Exhibits, Financial Statement Schedules” Note 15 — Income Taxes.

Critical Accounting Estimates

Our results of operations and financial condition, as reflected in our consolidated financial statements, have been prepared in accordance with accounting principles generally accepted in the United States of America. Preparation of financial statements requires us to make estimates and assumptions affecting the reported amounts of assets, liabilities, revenues and expenses and the disclosures of contingent assets and liabilities. We use historical experience and other relevant factors when developing estimates and assumptions and these estimates and assumptions are continually evaluated. The accounting estimates discussed below are the ones we consider to be most critical to an understanding of our consolidated financial statements because their application places the most significant demands on our judgment. Our financial results may have varied from those reported had different assumptions been used or other conditions prevailed.

Revenue Recognition

Sales are recognized as revenue at a point in time upon transferring control of the product to the customer. This typically occurs when products are shipped or delivered, depending on when risks of loss and title have passed to the customer per the terms of the contract. For certain of our sales we must make judgments and certain assumptions in order to determine when delivery has occurred. Through an analysis of end-of-period shipments for these particular sales, we estimate the time of transit and delivery of product to our customers to determine whether revenue should be recognized during the current reporting period for such shipments. Differences in judgments or estimates related to the lengthening or shortening of the estimated delivery time used could result in material differences in the timing of revenue recognition.

In determining the transaction price, management evaluates whether the price is subject to refunds or adjustments related to variable consideration to determine the net consideration to which we expect to be entitled. We record estimates of variable consideration as a reduction of sales in the consolidated statements of operations. Variable consideration primarily includes rebates/other discounts (cooperative marketing programs, volume-based discounts, shelf price reductions and allowances for shelf space, charges from customers for services they provided to us related to the sale and penalties/fines charged to us by our customers for failing to adhere to contractual obligations), coupon offers, cash discount allowances, and sales returns. These estimates are based on the expected value method considering all reasonably available information, including current and past trade promotion spending patterns, status of trade promotion activities and the interpretation of historical spending trends by customer and category, customer agreements and/or currently known factors that arise in the normal course of business. We review our assumptions and adjust these estimates accordingly on a quarterly basis. Our consolidated financial statements could be materially impacted if the actual promotion rates are different from the estimated rates. If our accrual estimates for sales incentives at August 31, 2025 were to differ by 10%, the impact on net sales would be approximately $1.2 million.

Recently Issued Accounting Standards

Information on Recently Issued Accounting Standards that could potentially impact our consolidated financial statements and related disclosures is incorporated by reference to Part IV—Item 15, “Exhibits, Financial Statement Schedules” Note 2 — Basis of Presentation and Summary of Significant Accounting Policies, included in this report.

Item 7A. Quantitative and Qualitative Disclosures About Market Risk

Foreign Currency Risk

We are exposed to a variety of risks, including foreign currency exchange rate fluctuations. In the normal course of business, we employ established policies and procedures to manage our exposure to fluctuations in foreign currency values.

Table of Contents

All of our international subsidiaries operate in functional currencies other than the U.S. Dollar. As a result, we are exposed to foreign currency related risk when the financial statements of our international subsidiaries are translated for consolidation purposes from functional currencies to U.S. Dollars. This foreign currency risk can affect sales, expenses and profits as well as assets and liabilities that are denominated in currencies other than the U.S. Dollar. We do not enter into any hedging activities to mitigate this foreign currency translation risk.

Our U.K. subsidiary utilizes foreign currency forward contracts to limit our exposure to net asset balances held in non-functional currencies. We regularly monitor our foreign exchange exposures to ensure the overall effectiveness of our foreign currency hedge positions. While we engage in foreign currency hedging activity to reduce our risk, for accounting purposes, none of our foreign currency forward contracts are designated as hedges.

Commodity Price Risk

Specialty chemicals and aerosol cans constitute a significant portion of the cost of many of our maintenance products. Volatility in the price of oil indirectly impacts the cost of specialty chemicals which are in part, indexed to related refined products. If there are significant increases in the costs of crude oil and related refined products, our gross margins and operating results could be negatively impacted. Since none of our specialty chemicals are directly indexed to crude oil, we do not have a strategy or policy to enter into transactions to hedge crude oil price volatility.

Interest Rate Risk

As of August 31, 2025, we had a $21.0 million outstanding balance on our existing $125.0 million revolving credit facility agreement with Bank of America, N.A. This $125.0 million revolving credit facility is subject to interest rate fluctuations. Under the terms of the credit facility agreement, we make borrowings in U.S. Dollars or in foreign currencies from time to time until April 30, 2029. In addition, we had $66.0 million in fixed rate borrowings consisting of senior notes under our note purchase agreements as of August 31, 2025. For additional details on our long-term borrowings as of August 31, 2025, refer to the information set forth in Part IV—Item 15, “Exhibits, Financial Statement Schedules” and Note 10 — Debt. Interest rates associated with this revolving credit facility are based on the following rates:

•Secured Overnight Financing Rate (U.S. Dollar borrowings)

•Sterling Overnight Index Average Reference Rate (Pound Sterling borrowings)

•Euro Interbank Offered Rate (Euro borrowings)

As of August 31, 2025, our primary interest rate exposure was from changes in interest rates which affect the variable rate on our revolving credit facility. Based on the outstanding balance on our revolving credit facility as of August 31, 2025, the annualized effect of a one percentage point increase in variable interest rates would have resulted in a pretax reduction of our earnings and cash flows of approximately $0.3 million in fiscal year 2025. As of August 31, 2025, our weighted average cost of short-term debt, including both fixed and variable rate borrowings, was 5.5%.

Item 8. Financial Statements and Supplementary Data

Our consolidated financial statements at August 31, 2025 and 2024 and for each of the three fiscal years in the period ended August 31, 2025, and the Report of Independent Registered Public Accounting Firm, are included in Item 15 of this report.

Item 9. Changes in and Disagreements With Accountants on Accounting and Financial Disclosure

None.

Item 9A. Controls and Procedures

Evaluation of Disclosure Controls and Procedures

We maintain disclosure controls and procedures designed to ensure that information required to be disclosed by a company in the reports that it files or submits under the Exchange Act is accumulated and communicated to the Company’s management, including its principal executive and principal financial officers, or persons performing similar functions, as

Table of Contents

appropriate to allow timely decisions regarding required disclosures. The Company’s Chief Executive Officer and Chief Financial Officer have evaluated the effectiveness of the Company’s disclosure controls and procedures as of August 31, 2025, the end of the period covered by this report (the “Evaluation Date”), and they have concluded that, as of the Evaluation Date, such controls and procedures were effective at ensuring that required information will be disclosed on a timely basis in the Company’s reports filed under the Exchange Act. Although management believes the Company’s existing disclosure controls and procedures are adequate to enable the Company to comply with its disclosure obligations, management continues to review and update such controls and procedures. The Company has a disclosure committee, which consists of certain members of the Company’s senior management.

Management’s Report on Internal Control over Financial Reporting

Management is responsible for establishing and maintaining adequate internal control over financial reporting, as such term is defined in Exchange Act Rule 13a-15(f). Under the supervision and with the participation of our Chief Executive Officer and Chief Financial Officer, management conducted an evaluation of the effectiveness of its internal control over financial reporting based upon the framework in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission in 2013. Based on that evaluation, management concluded that its internal control over financial reporting is effective as of August 31, 2025.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

PricewaterhouseCoopers LLP, an independent registered public accounting firm, which audited and reported on the consolidated financial statements of the Company included in Item 15 of this report, has audited the effectiveness of the Company’s internal control over financial reporting as of August 31, 2025, as stated in their report included in Item 15 of this report.

Changes in Internal Control over Financial Reporting

There were no changes to the Company’s internal control over financial reporting that occurred during the Company’s most recent fiscal quarter ended August 31, 2025, that materially affected, or would be reasonably likely to materially affect, the Company’s internal control over financial reporting.

Item 9B. Other Information

Report of Independent Registered Public Accounting Firm

To the Board of Directors and Stockholders of WD-40 Company

Opinions on the Financial Statements and Internal Control over Financial Reporting

We have audited the accompanying consolidated balance sheets of WD-40 Company and its subsidiaries (the “Company”) as of August 31, 2025 and 2024, and the related consolidated statements of operations, of comprehensive income, of stockholders’ equity and of cash flows for each of the three years in the period ended August 31, 2025, including the related notes (collectively referred to as the “consolidated financial statements”). We also have audited the Company’s internal control over financial reporting as of August 31, 2025, based on criteria established in Internal Control—Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO).

In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of the Company as of August 31, 2025 and 2024, and the results of its operations and its cash flows for each of the three years in the period ended August 31, 2025 in conformity with accounting principles generally accepted in the United States of America. Also in our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of August 31, 2025, based on criteria established in Internal Control—Integrated Framework (2013) issued by the COSO.

Basis for Opinions

The Company’s management is responsible for these consolidated financial statements, for maintaining effective internal control over financial reporting, and for its assessment of the effectiveness of internal control over financial reporting, included in Management’s Report on Internal Control over Financial Reporting appearing under Item 9A. Our responsibility is to express opinions on the Company’s consolidated financial statements and on the Company’s internal control over financial reporting based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud, and whether effective internal control over financial reporting was maintained in all material respects.

Our audits of the consolidated financial statements included performing procedures to assess the risks of material misstatement of the consolidated financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the consolidated financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audits also included performing such other procedures as we considered necessary in the circumstances. We believe that our audits provide a reasonable basis for our opinions.

Definition and Limitations of Internal Control over Financial Reporting

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (ii) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and

F-1

Table of Contents

directors of the company; and (iii) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.

Critical Audit Matters

The critical audit matter communicated below is a matter arising from the current period audit of the consolidated financial statements that was communicated or required to be communicated to the audit committee and that (i) relates to accounts or disclosures that are material to the consolidated financial statements and (ii) involved our especially challenging, subjective, or complex judgments. The communication of critical audit matters does not alter in any way our opinion on the consolidated financial statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing a separate opinion on the critical audit matter or on the accounts or disclosures to which it relates.

Revenue Recognition – Product Sales

As described in Notes 2 and 13 to the consolidated financial statements, product sales make up a majority of the Company’s net sales of $620.0 million for the year ended August 31, 2025. The Company generates revenue from sales of its products to customers. Product sales include maintenance products and homecare and cleaning products. As disclosed by management, sales are recognized as revenue at a point in time upon transferring control of the product to the customer, which typically occurs when products are shipped or delivered, depending on when risks of loss and title have passed to the customer per the terms of the contract. The Company recognizes revenue related to the sale of these products in an amount reflecting the consideration to which it expects to be entitled.

The principal consideration for our determination that performing procedures relating to revenue recognition for product sales is a critical audit matter is a high degree of auditor effort involved in performing procedures related to the Company’s revenue recognition.

Addressing the matter involved performing procedures and evaluating audit evidence in connection with forming our overall opinion on the consolidated financial statements. These procedures included testing the effectiveness of controls relating to product sales revenue recognition, including controls over the recording of product sales at the point in time upon transferring control to the customer. These procedures also included, among others (i) testing the revenue recognized for a sample of revenue transactions by obtaining and inspecting source documents, such as purchase orders, invoices, proof of shipment or delivery, and cash receipts and (ii) confirming a sample of outstanding customer invoice balances as of August 31, 2025 and, for confirmations not returned, obtaining and inspecting source documents, such as purchase orders, invoices, proof of shipment or delivery, and subsequent cash receipts.

Note 2. Basis of Presentation and Summary of Significant Accounting Policies

Basis of Consolidation

The consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. All intercompany transactions and balances have been eliminated in consolidation.

Use of Estimates

The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America (“U.S. GAAP”) requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues and expenses and the disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting periods. Actual results could materially differ from those estimates.

Global economies have experienced significant volatility in recent years. Although the Company’s estimates consider current conditions, the inputs into certain of the Company’s significant and critical accounting estimates include judgments and assumptions about the economic implications of factors that have been subject to such volatility and how management expects them to change in the future, as appropriate. It is possible that actual results experienced may materially differ from the Company’s estimates in future periods, which could materially affect its results of operations and financial condition.

Cash and Cash Equivalents

Cash equivalents are highly liquid investments purchased with an original maturity of three months or less.

Trade Accounts Receivable and Allowance for Credit Losses

Trade accounts receivable are recorded at the invoiced amount and do not bear interest. The allowance for credit losses is the Company’s best estimate of the amount of probable credit losses in existing accounts receivable. The Company determines the allowance for credit losses based on historical write-off experience and the identification of specific balances deemed uncollectible. Trade accounts receivable are charged against the allowance when the Company believes it is probable that the trade accounts receivable will not be recovered. The Company does not have any off-balance sheet credit exposure related to its customers. Allowance for credit losses related to the Company’s trade accounts receivable was $1.2 million at August 31, 2025 and not significant at 2024 and 2023.

Inventories

Inventories are stated at the lower of cost or net realizable value. Cost is determined primarily based on a first-in, first-out method or, for a portion of raw materials inventory, the average cost method. When necessary, the Company adjusts the

F-8

Table of Contents

carrying value of its inventory to the lower of cost or net realizable value, including any costs to sell or dispose of such inventory. Appropriate consideration is given by the Company to obsolescence, excessive inventory levels, product deterioration and other factors when evaluating net realizable value for the purposes of determining the lower of cost or net realizable value.

Included in inventories are amounts for certain raw materials and components that the Company has provided to its third-party contract manufacturers but that remain unpaid to the Company as of the balance sheet date. The Company’s contract manufacturers package products to the Company’s specifications and, upon order from the Company, ship ready-to-sell inventory to either the Company’s third-party distribution centers or directly to its customers. The Company transfers certain raw materials and components to these contract manufacturers for use in the manufacturing process. Contract manufacturers are obligated to pay the Company for these raw materials and components. Amounts receivable from the contract manufacturers as of the balance sheet date related to transfers of these raw materials and components by the Company to its contract manufacturers are generally considered product held at third-party contract manufacturers and are included in inventories in the accompanying consolidated balance sheets.

Property and Equipment

Property and equipment is stated at cost, and when placed into service, are depreciated using the straight line method over the following ranges of useful lives:


Machinery, equipment and vehicles			3 - 15 years
Buildings and improvements			10 - 40 years
Computer and office equipment			3 - 7 years

Furniture and fixtures			3 - 10 years

Depreciation expense totaled $7.6 million, $8.0 million and $7.1 million for fiscal years 2025, 2024 and 2023, respectively. These amounts include equipment depreciation expense which is recognized as cost of products sold and totaled $4.0 million, $3.9 million, and $3.0 million in fiscal years 2025, 2024, and 2023, respectively.

Internal-Use Software and Cloud Computing Arrangements

The Company capitalizes costs related to computer software obtained or developed for internal use. Software obtained for internal use has generally been enterprise-level business and finance software that the Company customizes to meet its specific operational needs. Costs incurred in the application development phase are capitalized as property and equipment in the Company’s consolidated balance sheets and are depreciated using the straight-line method over their estimated useful lives.

The Company also enters into certain cloud-based software hosting arrangements. In evaluating whether cloud computing arrangements include an embedded internal-use software license, management considers whether the Company has the contractual right to take possession of the software during the hosting period without significant penalty and whether it is feasible to either i) run the software on the Company’s hardware, or ii) contract with another party unrelated to the vendor to host the software. If management determines a cloud computing arrangement includes an embedded software license, the Company accounts for the software license element of the arrangement consistent with the acquisition of other internal-use software licenses. If a cloud computing arrangement does not include a software license, the Company accounts for the arrangement as a service contract. For such cloud computing service contracts, the Company capitalizes certain implementation costs such as the configuration, coding and customization of the software. Capitalizable cloud computing arrangement costs are generally consistent with those incurred during the application development stage for internal-use software, however, these costs are capitalized as “other assets” in the Company’s consolidated balance sheets. The Company amortizes these capitalized cloud computing implementation costs into selling, general and administrative expenses using the straight-line method over the fixed, non-cancellable term of the associated hosting arrangement, plus any reasonably certain renewal periods.

The useful lives of the Company’s internal-use software and capitalized cloud computing implementation costs are generally three to five years. However, the useful lives of major information system installations such as implementations of enterprise resource planning (“ERP”) systems and certain related software are determined on an individual basis and may exceed five years depending on the estimated period of use. The Company applies the same impairment model to both internal-use software and capitalized cloud computing implementation costs.

Leases

To determine if a contract contains a lease, the Company assesses its contracts and determines if there is an identified asset for which the Company has obtained the right to control, as defined in Accounting Standards Codification (“ASC”) 842. Right-of-use (“ROU”) assets and lease liabilities are recognized based on the present value of lease payments over the lease term with lease expense recognized over the term of the lease. For leases that do not contain a readily determinable implicit rate, the Company determines the present value of the lease liability at the lease commencement date using its estimated secured incremental borrowing rate, determined by using a portfolio approach based on the rate of interest the Company would have to pay to borrow an amount equal to the lease payments on a collateralized basis over a similar term. The Company uses the unsecured borrowing rate and risk-adjusts that rate to approximate a collateralized rate in the currency of the lease. The Company records ROU assets and lease liabilities on its consolidated balance sheets for leases with an expected term greater than one year.

Lease agreements may contain rent escalation clauses, renewal or termination options, and rent holidays, amongst other features. ROU assets include amounts for scheduled rent increases. The lease term includes the committed, non-cancelable period of the lease and options to renew, extend or terminate the lease when it is reasonably certain the Company will exercise those options, and is reviewed in subsequent periods if a triggering event occurs. The Company has made the accounting policy election to use certain ongoing practical expedients made available by ASC 842 to: (i) not separate lease components from non-lease components for real estate – office buildings, machinery and equipment, lab equipment, office equipment, furniture and fixtures, IT equipment and third-party manufacturing facilities; and (ii) exclude leases with a term of twelve months or less (“short-term” leases) from the consolidated balance sheets and recognize related lease payments in the consolidated statements of operations on a straight-line basis over the lease term.

Goodwill

Goodwill represents the excess of the purchase price over the fair value of tangible and intangible assets acquired. The carrying value of goodwill is reviewed for possible impairment in accordance with the authoritative guidance on goodwill, intangibles and other. The Company assesses possible impairments to goodwill at least annually during its second fiscal quarter and otherwise when events or changes in circumstances indicate that an impairment condition may exist. In performing the annual impairment test of its goodwill, the Company considers the fair value concepts of a market participant and the highest and best use for its intangible assets. In addition to the annual impairment test, goodwill is evaluated each reporting period to determine whether events and circumstances would more likely than not reduce the fair value of a reporting unit below its carrying value.

When testing goodwill for impairment, the Company first assesses qualitative factors to determine whether it is necessary to perform a quantitative goodwill impairment test. If, after assessing qualitative factors, the Company determines it is not more likely than not that the fair value of a reporting unit is less than its carrying amount, then performing a quantitative test is unnecessary. Otherwise, a quantitative test is performed to identify the potential impairment and to measure the amount of goodwill impairment, if any. The Company also performs a quantitative assessment periodically, regardless of the results of the qualitative assessments. Any required impairment losses are recorded as a reduction in the carrying amount of the related asset and charged to results of operations. No goodwill impairments were identified by the Company during fiscal years 2025, 2024 or 2023.

Subsequent Measurement of Long-lived Assets

The Company’s long-lived assets consist of property and equipment and definite-lived intangible assets. Long-lived assets are depreciated or amortized, as applicable, on a straight-line basis over their estimated useful lives. The Company assesses for potential impairments to its long-lived assets when there is evidence that events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable and/or its remaining useful life may no longer be appropriate. Any required impairment loss would be measured as the amount by which the asset’s carrying amount exceeds its fair value, which is the amount at which the asset could be bought or sold in a current transaction between willing market participants and would be recorded as a reduction in the carrying amount of the related asset and a charge to results of operations. An impairment loss would be recognized when the sum of the expected future undiscounted net cash flows is less than the carrying amount of the asset. No impairments to its long-lived assets were identified by the Company during fiscal years 2025, 2024 or 2023.

Table of Contents

Fair Value of Financial Instruments

ASC 820, “Fair Value Measurements and Disclosures”, defines fair value as the exchange price that would be received for an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The Company categorizes its financial assets and liabilities measured at fair value into a hierarchy that categorizes fair value measurements into the following three levels based on the types of inputs used in measuring their fair value:

Level 1: Observable inputs such as quoted market prices in active markets for identical assets or liabilities;

Level 2: Observable market-based inputs or observable inputs that are corroborated by market data; and

Level 3: Unobservable inputs reflecting the Company’s own assumptions.

Under fair value accounting, assets and liabilities are classified in their entirety based on the lowest level of input that is significant to the fair value measurement. As of August 31, 2025, the Company had no assets or liabilities that are measured at fair value in the financial statements on a recurring basis, with the exception of the foreign currency forward contracts, which are classified as Level 2 within the fair value hierarchy. The carrying values of cash equivalents and short-term borrowings are recorded at cost, which approximates their fair values, primarily due to their short-term nature. In addition, the carrying value of borrowings held under the Company’s revolving credit facility approximates fair value, based on Level 2 inputs, due to the variable nature of underlying interest rates, which generally reflect market conditions. The Company’s fixed rate long-term borrowings consist of senior notes and are recorded at carrying value. The Company estimates that the fair value of its senior notes, based on Level 2 inputs, was approximately $61.2 million as of August 31, 2025, which was determined based on a discounted cash flow analysis using current market interest rates for instruments with similar terms, compared to their carrying value of $66.0 million. During the fiscal years ended August 31, 2025, 2024 and 2023, the Company did not record any significant nonrecurring fair value measurements for assets or liabilities in periods subsequent to their initial recognition.

Concentration of Credit Risk

Financial instruments, which potentially subject the Company to significant concentrations of credit risk, consist principally of cash and cash equivalents and trade accounts receivable. The Company’s policy is to place its cash in high credit quality financial institutions, in investments that include demand deposits, term deposits and callable time deposits. The Company’s trade accounts receivable are derived from customers located in North, Central and South America, Asia-Pacific, Europe, India, the Middle East, and Africa. The Company limits its credit exposure from trade accounts receivable by performing on-going credit evaluations of customers, as well as insuring its trade accounts receivable in selected markets.

Concentration of Supplier Risk

The Company relies on a limited number of suppliers, including single or sole source suppliers for certain of its raw materials, packaging, product components and other necessary supplies. Historically, the Company has been able to obtain adequate supplies of these materials which are used in the production of its maintenance products and homecare and cleaning products in a timely manner from existing sources and has been able to access adequate production capacity at its third-party manufacturers. Where possible and where it makes business sense, the Company works with secondary or multiple suppliers to qualify additional supply sources.

Insurance Coverage

The Company carries insurance policies to cover insurable risks such as property damage, business interruption, product liability, cyber liability, workers’ compensation and other risks, with coverage and other terms that it believes to be adequate and appropriate. These policies may be subject to applicable deductible or retention amounts, coverage limitations and exclusions. The Company does not maintain self-insurance with respect to its material risks; therefore, the Company has not provided for self-insurance reserves as of August 31, 2025 and 2024.

Revenue Recognition

The Company generates revenue from sales of its products to customers in its Americas, EIMEA and Asia-Pacific segments. Product sales for the Company include maintenance products and homecare and cleaning products. The Company recognizes revenue related to the sale of these products when it satisfies a performance obligation in an amount reflecting the consideration to which it expects to be entitled. Sales are recorded net of allowances for damaged goods and

F-11

Table of Contents

other sales returns, sales incentives, trade promotions and cash discounts. The Company applies a five-step approach in determining the amount and timing of revenue to be recognized which includes the following: (1) identifying the contract with a customer, (2) identifying the performance obligations in the contract, (3) determining the transaction price, (4) allocating the transaction price to the performance obligations in the contract and (5) recognizing revenue when the performance obligation is satisfied.

Contracts with customers are renewable periodically and contain terms and conditions with respect to payment, delivery, sales incentives, warranty and supply, but do not require mandatory purchase commitments. In the absence of a specific sales agreement with a customer, the Company’s standard terms and conditions at the time of acceptance of purchase orders apply to the sales transaction. The Company’s standard terms and conditions are either included in a standalone document or on the Company’s price lists or both, and these standard terms and conditions are provided to the customer prior to the sales transaction. The Company considers the customer purchase orders, governed by specific sales agreements or the Company’s standard terms and conditions, to be the contract with the customer. The Company considers each transaction to sell products as separate and distinct, with no additional promises made, and as a result, all of the Company’s sales are single performance obligation arrangements for which the transaction price is equivalent to the stated price of the product, net of any variable consideration for items such as sales returns, discounts, rebates and other sales incentives. The Company recognizes sales at a point in time upon transferring control of its product to the customer. This typically occurs when products are shipped or delivered, depending on when risks of loss and title have passed to the customer per the terms of the contract.

Taxes imposed by governmental authorities on the Company’s revenue, such as sales taxes and value added taxes, are excluded from net sales. Sales commissions are paid to certain third-parties based upon specific sales levels achieved during a defined time period. Since the Company’s contracts related to these sales commissions do not exceed one year, the Company has elected as a practical expedient to expense these payments as incurred. The Company also elected the practical expedient related to shipping and handling fees which allows the Company to account for freight costs as fulfillment activities instead of assessing such activities as performance obligations. The Company’s freight costs are sometimes paid by the customer, while other times, the freight costs are included in the sales price. The Company does not account for freight costs as a separate performance obligation, but rather as an activity performed to transfer the products to its customers.

Variable Consideration – Sales Incentives

In determining the transaction price, the Company evaluates whether the price is subject to refund or adjustment related to variable consideration to determine the net consideration to which the Company expects to be entitled. The Company records estimates of variable consideration, which primarily includes rebates/other discounts (cooperative marketing programs, volume-based discounts, shelf price reductions and allowances for shelf space, charges from customers for services they provided to us related to the sale and penalties/fines charged to us by customers associated with failing to adhere to contractual obligations), coupon offers, cash discount allowances, and sales returns, as a reduction of sales in its consolidated statements of operations. These estimates are based on the expected value method considering all reasonably available information, including current and past trade promotion spending patterns, status of trade promotion activities, the interpretation of historical spending trends by customer and category, customer agreements and/or currently known factors that arise in the normal course of business. The Company reviews its assumptions and adjusts these estimates accordingly on a quarterly basis.

Rebates and Other Discounts

The Company offers various on-going trade promotion programs with customers and provides other discounts to customers that require management to estimate and accrue for the expected costs of such programs or discounts. These programs include cooperative marketing, volume-based discounts, shelf price reductions, consideration and allowances given to retailers for shelf space and/or favorable display positions in their stores and other promotional activities. Other discounts include items such as charges from customers for services they provide related to the sale of WD-40 Company products and penalties/fees associated with WD-40 Company failing to adhere to contractual obligations (e.g., errors on purchase orders, errors on shipment, late deliveries, etc.). Costs related to rebates, cooperative advertising and other promotional activities and other discounts are recorded as a reduction to sales upon delivery of the Company’s products to its customers.

F-12

Table of Contents

The Company offers certain of its customers a cash discount program to incentivize them to pay the invoice earlier than the normal payment date on the invoice. Although payment terms vary, most customers typically pay within 30 to 90 days of invoicing.

Sales Returns

The Company recognizes revenue net of allowances for estimated returns, which is generally based on historical return rates, with a corresponding reduction to cost of products sold. Although the Company typically does not have definitive sales return provisions included in the contract terms with its customers, when such provisions have been included, they have not been significant. The Company presents its provision for sales returns on a gross basis as a liability. The Company’s refund liability for sales returns is included in accrued liabilities and represents the amount expected to be owed to the customers for product returns.

Contract Balances

Contract liabilities consist of deferred revenue related to undelivered products. Deferred revenue is recorded when payments have been received from customers for undelivered products. Revenue is subsequently recognized when revenue recognition criteria are met, generally when control of the product transfers to the customer. Contract liabilities are recorded in accrued liabilities on the Company’s consolidated balance sheets. Contract assets are recorded if the Company has satisfied a performance obligation but does not yet have an unconditional right to consideration. The Company has an unconditional right to payment for its trade and other accounts receivable on the Company’s consolidated balance sheets.

Cost of Products Sold

Cost of products sold primarily includes the cost of products manufactured on the Company’s behalf by its third-party contract manufacturers, net of volume and other rebates. Cost of products sold also includes the costs to manufacture WD-40 concentrate, which is done at the Company’s own facilities or at third-party contract manufacturers. When the concentrate is manufactured by the Company, cost of products sold includes direct labor, direct materials and supplies; in-bound freight costs related to purchased raw materials and finished product; and depreciation of machinery and equipment used in the manufacturing process. In addition, cost of products sold includes fees charged to the Company by its third-party distribution centers to warehouse and administer finished products once they are received from the Company’s third-party contract manufacturers.

Selling, General and Administrative Expenses

Selling, general and administrative expenses include costs related to selling the Company’s products, such as the cost of the sales force and broker commissions; shipping and handling costs paid to third-party companies to distribute finished goods from the Company’s third-party contract manufacturers and distribution centers to its customers; other general and administrative costs related to the Company’s business such as general overhead, legal and accounting fees, insurance, and depreciation; and employee-related and various other costs to support marketing, human resources, finance, supply chain, information technology and research and development activities.

Shipping and Handling Costs

Shipping and handling costs associated with the movement of finished goods from third-party contract manufacturers to the Company’s third-party distribution centers and from one third-party distribution center to another are capitalized in the cost of inventory and subsequently included in cost of sales when the sale to the customer is recognized in the consolidated statements of operations. Shipping and handling costs associated with out-bound transportation are included in selling, general and administrative expenses and are recorded at the time of shipment of product to the Company’s customers. Out-bound shipping and handling costs were $18.2 million, $17.3 million and $17.1 million for fiscal years 2025, 2024 and 2023, respectively.

Advertising and Sales Promotion Expenses

Advertising and sales promotion expenses are expensed as incurred. Advertising and sales promotion expenses include costs for advertising (television, print media and internet), administration of coupon programs, samples programs and product demonstrations, advertising agency costs, package design expenses, market research costs, and retail sales data

F-13

Table of Contents

services. Advertising and sales promotion expenses also include shared marketing fund programs that the Company has in place with its marketing distributor customers.

Research and Development

The Company is involved in research and development efforts, including efforts focused on sustainability as well as ongoing development or innovation of new products and the improvement, extension or renovation of existing products or product lines. All research and development costs are expensed as incurred and are included in selling, general and administrative expenses. Research and development expenses were $8.7 million, $8.0 million and $6.2 million in fiscal years 2025, 2024 and 2023, respectively. These expenses include costs associated with general research and development activities, as well as those associated with internal staff, overhead, design testing, market research and consultants.

Income Taxes

Current income tax expense is the amount of income taxes expected to be payable for the current year. A deferred income tax liability or asset is established for the expected future tax consequences resulting from the differences in financial reporting and tax basis of assets and liabilities. A valuation allowance is provided if it is more likely than not that some or all of the deferred tax assets will not be realized. In addition to valuation allowances, the Company provides for uncertain tax positions when such tax positions do not meet the recognition thresholds or measurement standards prescribed by the authoritative guidance on income taxes. Amounts for uncertain tax positions are adjusted in periods when new information becomes available or when positions are effectively settled. The Company recognizes accrued interest and penalties related to uncertain tax positions as a component of income tax expense.

The Company is required to make assertions on whether its foreign subsidiaries will invest their undistributed earnings indefinitely and these assertions are based on the capital needs of the foreign subsidiaries. Generally, unremitted earnings of the Company’s foreign subsidiaries are not considered to be indefinitely reinvested. However, there is an exception regarding specific statutory remittance restrictions imposed on the Company’s China subsidiary. Costs associated with repatriating unremitted foreign earnings, including U.S. state income taxes and foreign withholding taxes, are immaterial to the Company’s consolidated financial statements. For additional information on income tax matters, see Note 15 — Income Taxes, included in this report.

Foreign Currency

The Company translates the assets and liabilities of its foreign subsidiaries into U.S. Dollars at current rates of exchange in effect at the end of the reporting period. Income and expense items are translated at rates that approximate the rates in effect at the transaction date. Gains and losses from translation are included in accumulated other comprehensive income or loss. Gains or losses resulting from foreign currency transactions (transactions denominated in a currency other than the entity’s functional currency) are included as other income in the Company’s consolidated statements of operations. The Company had $0.7 million in net gains, $1.3 million in net losses, and $0.5 million in net gains in foreign currency transactions in fiscal years 2025, 2024, and 2023, respectively.

In the normal course of business, the Company employs established policies and procedures to manage its exposure to fluctuations in foreign currency exchange rates. The Company utilizes foreign currency forward contracts to limit its exposure to net asset balances held in non-functional currencies, primarily at its U.K. subsidiary. The Company monitors its foreign currency exchange rate exposures to ensure the overall effectiveness of its foreign currency hedge positions. While the Company engages in foreign currency hedging activity to reduce its risk, for accounting purposes, none of its foreign currency forward contracts are designated as hedges.

Foreign currency forward contracts are carried at fair value, with net realized and unrealized gains and losses recognized in other income (expense), net in the Company’s consolidated statements of operations. Cash flows from settlements of foreign currency forward contracts are included in operating activities in the consolidated statements of cash flows. Foreign currency forward contracts in an asset position at the end of the reporting period are included in other current assets, while foreign currency forward contracts in a liability position at the end of the reporting period are included in accrued liabilities in the Company’s consolidated balance sheets. At August 31, 2025, the Company had a notional amount of $2.8 million outstanding in foreign currency forward contracts, which matured in September 25, 2025. Unrealized net gains and losses related to foreign currency forward contracts were not significant at August 31, 2025, 2024 and 2023. Realized net gains and losses related to foreign currency forward contracts were not significant for the fiscal years ended August 31, 2025,

2024 and 2023. Both unrealized and realized net gains and losses are recorded in other income (expense), net in the Company’s consolidated statements of operations.

The reporting currency of the Company is the U.S. Dollar. The functional currency of each of the Company’s subsidiaries is based on the currency of the economic environment in which it operates. Management periodically assesses the functional currency of each subsidiary in accordance with ASC 830, “Foreign Currency Matters”.

The functional currency of the Company’s U.K. subsidiary, the entity in which the EIMEA results are generated, had been the Pound Sterling through August 31, 2024. However, trends within EIMEA have indicated a shift towards the Euro over time. During the first quarter of fiscal year 2025, management determined that changes in economic facts and circumstances, such as additional shifts in the currency mix of our operating income, represented a significant change that was other-than-temporary and required a change in functional currency from Pound Sterling to Euro at the Company’s U.K. subsidiary. In accordance with ASC 830-10-45-7, a change in functional currency should be made on the date that significant changes in economic facts and circumstances occurred. Although such a change could occur on any date during the fiscal year, the use of a date at the beginning of the most recent reporting period is permissible. Accordingly, the change in functional currency from Pound Sterling to Euro at the Company’s U.K. subsidiary was accounted for prospectively from September 1, 2024.

In the period of a functional currency change, nonmonetary assets and liabilities at the impacted subsidiary are remeasured into the new functional currency using the exchange rate on the date the asset or liability arose. These amounts are then translated into the Company’s reporting currency, the U.S. Dollar, based on the exchange rate at the date of the change in functional currency. The difference between this amount and the prior translated balance was not material and was recorded in accumulated other comprehensive loss in the Company’s consolidated balance sheets as of September 1, 2024. The balances previously recorded in accumulated comprehensive loss for prior periods through August 31, 2024 were not reversed upon this prospective change in functional currency. Monetary assets and liabilities not denominated in the new functional currency, the Euro, will create transaction gains and losses subsequent to the change in functional currency. The Company does not expect that the impact of such gains and losses will be material to the Company’s consolidated statements of operations.

Earnings per Common Share

Unvested share-based payment awards that contain nonforfeitable rights to dividends or dividend equivalents, whether paid or unpaid, are participating securities that are required to be included in the computation of earnings per common share pursuant to the two-class method. Accordingly, the Company’s outstanding unvested, if any, and outstanding vested stock-based equity awards that provide such nonforfeitable rights to dividend equivalents are included as participating securities in the calculation of earnings per common share (“EPS”) pursuant to the two-class method.

The Company calculates EPS using the two-class method, which provides for an allocation of net income between common stock and other participating securities based on their respective participation rights to share in dividends. Basic EPS is calculated by dividing net income available to common stockholders for the period by the weighted-average number of common shares outstanding during the period. Net income available to common stockholders for the period includes dividends paid to common stockholders during the period plus a proportionate share of undistributed net income allocable to common stockholders for the period; the proportionate share of undistributed net income allocable to common stockholders for the period is based on the proportionate share of total weighted-average common shares and participating securities outstanding during the period.

Diluted EPS is calculated by dividing net income available to common stockholders for the period by the weighted-average number of common shares outstanding during the period increased by the weighted-average number of potentially dilutive common shares (dilutive securities) that were outstanding during the period if the effect is dilutive. Dilutive securities are comprised of various types of stock-based equity awards granted under the Company’s prior and current equity incentive plans.

Stock-based Compensation

The Company accounts for stock-based equity awards exchanged for employee and nonemployee director services in accordance with the authoritative guidance for share-based payments. Stock-based equity awards are measured at the

F-15

Table of Contents

estimated grant date fair value and expensed on a straight-line basis, net of forfeitures recognized as they occur, over the requisite service period. The requisite service period of employee awards generally ranges from about one to three years, although awards of certain employees may have shorter requisite service periods as a result of retirement, death and disability provisions. Vesting of the RSUs granted to nonemployee directors is over a period of up to one year from the date of grant, with shares to be issued pursuant to the vested RSUs upon termination of each nonemployee director’s service as a director of the Company. Compensation expense related to the Company’s stock-based equity awards is recorded as selling, general and administrative expenses in the Company’s consolidated statements of operations.

The Company does not currently grant stock options. The fair values of restricted stock unit awards and performance share unit awards are based on the fair value of the Company’s common stock on the date that such awards are granted. The fair value of market share unit awards is determined using a Monte Carlo simulation model. For the performance share unit awards, the Company adjusts the compensation expense over the service period based upon the expected achievement level of the applicable performance condition. As the grant date fair value of market share unit awards reflects the probabilities of the actual number of such awards expected to vest, compensation expense for such awards is not adjusted based on the expected achievement level of the applicable performance condition. The Company records any excess tax benefits or deficiencies from settlements of its stock-based equity awards within the provision for income taxes on the Company’s consolidated statements of operations in the reporting periods in which the settlement of the equity awards occur.

Segment Information

The Company discloses certain information about its business segments, which are determined consistent with the way the Company’s Chief Operating Decision Maker (the “CODM”) organizes and evaluates financial information internally for making operating decisions and assessing performance. In addition, the CODM assesses and measures revenue based on product groups.

Recently Adopted Accounting Standards

In November 2023, the Financial Accounting Standards Board (the “FASB”) issued Accounting Standards Update (“ASU”) No. 2023-07, “Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures.” These amendments primarily require enhanced disclosures about significant segment expenses regularly provided to the Chief Operating Decision Maker and included within each reported measure of segment profit or loss. The Company adopted ASU 2023-07 with its annual period ended August 31, 2025. See Note 18 — Business Segments and Foreign Operations for updated disclosures as a result of the adoption.

Recently Issued Accounting Standards

In December 2023, the FASB issued ASU No. 2023-09, “Income Taxes (Topic 740): Improvements to Income Tax Disclosures,” which includes amendments that further enhance income tax disclosures, primarily through standardization and disaggregation of rate reconciliation categories and income taxes paid by jurisdiction. The amendments are effective for the Company’s annual periods beginning September 1, 2025. Adoption of this ASU will result in additional disclosures, but will not impact the Company’s consolidated financial position, results of operations or cash flows.

In November 2024, the FASB issued ASU No. 2024-03, “Income Statement—Reporting Comprehensive Income—Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses” which includes amendments that require disclosure in the notes to financial statements of specified information about certain costs and expenses. The amendments are effective for the Company’s annual periods beginning September 1, 2027, with early adoption permitted, and should be applied either prospectively or retrospectively. The Company is in the process of evaluating this ASU to determine its impact on the Company’s disclosures.

In July 2025, the FASB issued ASU No. 2025-05, “Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses for Accounts Receivable and Contract Assets” which includes amendments that provide all entities with a practical expedient when estimating expected credit losses for current accounts receivable and current contract assets. The amendments are effective for the Company’s annual periods beginning September 1, 2027, with early adoption permitted, and should be applied either prospectively or retrospectively. The Company is in the process of evaluating this ASU to determine its impact on the Company’s disclosures.

Note 3. Assets Held for Sale

Reclassification to Held for Sale of Certain Homecare and Cleaning Product Businesses

In the first quarter of fiscal year 2025, certain assets of the Company’s homecare and cleaning product businesses in the Americas and EIMEA segments met the criteria to be classified as held for sale. Management determined that the planned sale of these brands does not represent a strategic shift having a major effect on the Company’s operations and financial results and therefore does not meet the criteria for classification as discontinued operations in the first quarter of fiscal year 2025. During the fourth quarter of fiscal year 2025, we completed the sale of the Company’s business pertaining to homecare and cleaning products that are sold in EIMEA. As of August 31, 2025, the Company continues to classify as held for sale its homecare and cleaning product businesses in the Americas. Assets included as part of the disposal group classified as held for sale consisted of inventory, goodwill and other intangible assets, net. There are no liabilities in the disposal group.

The following table summarizes assets held for sale in the Americas segment (in thousands):


	August 31, 2025
Inventory	$	3,349
Goodwill	1,120

(1)Total assets held for sale are included in other current assets on the Company’s consolidated balance sheets.

Sale of Homecare and Cleaning Product Businesses in EIMEA

On August 29, 2025, the Company entered into an Asset Purchase Agreement (the “APA”) to sell its homecare and cleaning product business for total consideration of up to $7.5 million. Consideration under the APA consists of $1.7 million cash paid on the closing date, a $0.5 million payment due within twelve months, inventory consideration of up to $1.4 million due within one hundred twenty days, and annual contingent payments related to incremental revenue share as defined in the APA for an earn out period of four years, not to exceed $3.9 million in aggregate. Total consideration recognized for fiscal year 2025 was net of selling fees which resulted in an insignificant impact to the Company’s consolidated statements of operations in fiscal year 2025. Future payments related to the $3.9 million in contingent consideration related to the earn out will be recognized in the period they are earned and will be included in continuing operations on the consolidated statements of operations.

Note 4. Acquisitions

In fiscal year 2024, WD-40 Holding Company Brasil Ltda., a wholly-owned subsidiary of the Company, acquired all of the issued and outstanding capital stock of the Company’s Brazilian distributor, Theron Marketing Ltda. (“Theron”), from M12 Participações Empresarias S.A. for total consideration of $6.9 million. As of August 31, 2025 the Company’s remaining contingent consideration was insignificant related to this acquisition. With this transaction, the Company began direct distribution within Brazil in March 2024. There were no acquisitions in fiscal year 2025.

During the second quarter of fiscal year 2025, the Company performed its annual goodwill impairment test. The annual goodwill impairment test was performed at the reporting unit level as of the Company’s most recent goodwill impairment testing date, December 1, 2024. The Company performed a quantitative assessment to determine whether the fair value of any of its reporting units was less than each reporting unit’s carrying amount. The Company determined the fair value of its reporting units by following the income approach, which uses a discounted cash flow methodology. The discounted cash flow methodology bases the fair value of each reporting unit on the present value of its estimated future cash flows. The discounted cash flow methodology also requires that management make assumptions about certain key inputs in the estimated cash flows, including long-term sales forecasts or growth rates, terminal growth rates and discount rates, all of which are inherently uncertain. The forecast of future cash flows was primarily based on historical data and management’s best estimates of sales growth rates and operating margins for each reporting unit for the next five fiscal years. The discount rate used was based on management’s estimate of the current weighted-average cost of capital for each reporting unit. As these assumptions are largely unobservable, the estimated fair values fall within Level 3 of the fair value hierarchy. Based on quantitative analysis, the Company determined that the estimated fair value of each of its reporting units

F-19

significantly exceeded their respective carrying values. As a result, the Company concluded that no impairment of its goodwill existed as of December 1, 2024. In addition, the Company concluded that there were no indicators of impairment identified as a result of the Company’s review of events and circumstances related to its goodwill subsequent to December 1, 2024 through August 31, 2025. To date, there have been no impairment losses identified and recorded related to the Company’s goodwill.

Credit Agreement

On April 30, 2024, the Company and certain subsidiaries of the Company, entered into a Second Amended and Restated Credit Agreement with Bank of America, N.A. (the “Credit Agreement”). The Credit Agreement modified certain terms and conditions of the Company’s previous Amended and Restated Agreement dated March 16, 2020 (as amended on September 30, 2020, and November 29, 2021), and extended the maturity date for the revolving credit facility from

F-22

Table of Contents

September 30, 2025 to April 30, 2029. Borrowings under the Credit Agreement will be used for the Company’s various operating, investing and financing needs.

The Company’s Credit Agreement with Bank of America, N.A. consists of a revolving commitment for borrowing by the Company up to $125.0 million and with a sublimit from $95.0 million for WD-40 Company Limited, a wholly owned operating subsidiary of the Company for Europe, India, the Middle East and Africa.

Outstanding draws for which management has the ability and intent to refinance with successive short-term borrowings for a period of at least twelve months are classified as long-term. As of August 31, 2025, $21.0 million of this facility was classified as long-term and was entirely denominated in Euros. As of August 31, 2024, $20.0 million of this facility was classified as long-term and was denominated in Euros and Pounds Sterling; $7.8 million was classified as short-term and was denominated in U.S. Dollars. Euro and Pound Sterling denominated draws fluctuate in U.S. Dollars from period to period due to changes in foreign currency exchange rates.

(2)Principal payments are required semi-annually in May and November of each year in equal installments of $0.4 million through May 15, 2032, resulting in $0.8 million classified as short-term. The remaining outstanding principal in the amount of $8.4 million will become due on November 15, 2032.

(3)Interest on notes is payable semi-annually in May and November of each year with no principal due until the maturity date.

Both the Note Agreement and the Credit Agreement contain representations, warranties, events of default and remedies, as well as affirmative, negative and other financial covenants customary for these types of agreements. These covenants include, among other things, certain limitations on the ability of the Company and its subsidiaries to incur indebtedness, create liens, dispose of assets, make investments, declare, make or incur obligations to make certain restricted payments, including payments for the repurchase of the Company’s capital stock and enter into certain merger or consolidation transactions. The Credit Agreement includes, among other limitations on indebtedness, a $125.0 million limit on other unsecured indebtedness.

Each agreement also includes a most favored lender provision which requires that any time any other lender has the benefit of one or more financial or operational covenants that is different than, or similar to, but more restrictive than those contained in its own agreement, those covenants shall be immediately and automatically incorporated by reference to the other lender’s agreement. Both the Note Agreement and the Credit Agreement require the Company to adhere to the same financial covenants. For the financial covenants, the definition of consolidated EBITDA includes the add back of non-cash stock-based compensation to consolidated net income when arriving at consolidated EBITDA. The terms of the financial covenants are as follows:

•The consolidated leverage ratio cannot be greater than three and a half to one. The consolidated leverage ratio means, as of any date of determination, the ratio of (a) consolidated funded indebtedness as of such date to (b) consolidated EBITDA for the most recently completed four fiscal quarters.

As of August 31, 2025, the Company was in compliance with all debt covenants under both the Note Agreement and the Credit Agreement.

Note 11. Share Repurchase Plan

On June 19, 2023, the Company’s Board of Directors (the “Board”) approved a share repurchase plan (the “2023 Repurchase Plan”). Under the 2023 Repurchase Plan, which became effective on September 1, 2023, the Company is authorized to acquire up to $50.0 million of its outstanding shares through August 31, 2025. On June 16, 2025, the Board approved the extension of the expiration date to August 31, 2026 for the 2023 Repurchase Plan. During the fiscal year ended August 31, 2025, the Company repurchased 50,250 shares at an average price of $245.06 per share, for a total cost of $12.3 million under this $50.0 million plan. As of August 31, 2025, the Company is authorized to purchase an additional $29.6 million under the 2023 Repurchase Plan.

Note 14. Commitments and Contingencies

Purchase Commitments

The Company has ongoing relationships with various suppliers, third-party contract manufacturers that manufacture the Company’s products, and third-party distribution centers that warehouse and ship the Company’s products to customers. The contract manufacturers maintain title and control of certain raw materials and components, materials utilized in finished products, and the finished products themselves until shipment to the Company’s third-party distribution centers or customers in accordance with agreed-upon shipment terms. The Company has contractual minimum purchase obligations with certain contract manufacturers. The Company’s minimum purchase obligations primarily consist of contractual volume commitments with certain third-party packagers.

The following table summarizes minimum purchase obligations (in thousands):


	Minimum Purchase Obligation
Fiscal year 2026	$	6,785
Fiscal year 2027	4,481
Fiscal year 2028	1,833
Fiscal year 2029	1,547
Fiscal year 2030	1,473
Thereafter	616
Total	$	16,735

In addition to minimum purchase obligations above, supply needs are communicated in the ordinary course of business by the Company to its contract manufacturers based on orders and short-term projections, ranging from two months to six months. The Company is committed to purchase the products produced by the contract manufacturers based on the projections provided.

Upon the termination of contracts with contract manufacturers, the Company obtains certain inventory control rights and is obligated to work with the contract manufacturer to sell through all product held by or manufactured by the contract manufacturer on behalf of the Company during the termination notification period. If any inventory remains at the contract manufacturer at the termination date, the Company is obligated to purchase such inventory which may include raw materials, components and finished goods. The amounts for inventory purchased under termination commitments have been immaterial.

Litigation

The Company is subject to various claims, lawsuits, investigations and proceedings arising in the ordinary course of business, including but not limited to, product liability litigation and other claims and proceedings with respect to intellectual property, breach of contract, labor and employment, tax and other matters. As of August 31, 2025, there were no significant unasserted claims or pending proceedings for claims against the Company that the Company believes will result in a probable loss. As to claims that the Company believes may result in a reasonably possible loss, the Company believes that no reasonably possible outcome of any such claim will have a materially adverse impact on the Company’s financial condition, results of operations or cash flows.

Indemnifications

As permitted under Delaware law, the Company has agreements whereby it indemnifies senior officers and directors for certain events or occurrences while the officer or director is, or was, serving at the Company’s request in such capacity. The maximum potential amount of future payments the Company could be required to make under these indemnification agreements is not capped; however, the Company maintains Director and Officer insurance coverage that mitigates the Company’s exposure with respect to such obligations. As a result of the Company’s insurance coverage, management believes that the estimated fair value of these indemnification agreements is minimal. Thus, no liabilities have been recorded for these agreements as of August 31, 2025.

From time to time, the Company enters into indemnification agreements with certain parties in the ordinary course of business, including agreements with lenders, lessors, contract manufacturers, marketing distributors, customers and certain vendors. Indemnification agreements are generally entered into in the context of the particular agreements and are provided in an attempt to allocate risk of loss in connection with the consummation of the underlying contractual arrangements. Although the maximum amount of future payments that the Company could be required to make under these indemnification agreements is not capped, management believes that the Company maintains adequate levels of insurance coverage to protect the Company with respect to most potential claims arising from such agreements and that such agreements do not otherwise have value separate and apart from the liabilities incurred in the ordinary course of the Company’s business. Thus, no liabilities have been recorded with respect to such indemnification agreements as of August 31, 2025.

The Company had state net operating loss (“NOL”) carryforwards of $7.8 million as of August 31, 2025, which generated a net deferred tax asset of $0.5 million. The state NOL carryforwards, if unused, will expire between fiscal years 2026 and 2045. The Company also had tax credit carryforwards of $4.4 million as of August 31, 2025, of which $4.3 million is attributable to U.K. tax credit carryforwards, which do not expire.

Future utilization of the U.K. tax credit carryforwards and certain state carryforwards is uncertain and is dependent upon several factors that may not occur, including the generation of future taxable income in certain jurisdictions. At this time, management does not conclude that it is “more likely than not” that all of the related deferred tax assets will be realized. Accordingly, the Company recorded an insignificant change in its valuation allowance during the fiscal year ended August 31, 2025 and the cumulative valuation allowance recorded against the related deferred tax asset associated with the

On July 4, 2025, the One Big Beautiful Bill Act ("OBBB Act”) was enacted into law. The OBBB Act includes significant provisions, such as the permanent extension of certain expiring provisions of the Tax Cuts and Jobs Act, modifications to the international tax framework and the restoration of favorable tax treatment for certain business provisions. The significant provisions of the OBBB Act will be effective between fiscal years ended August 31, 2025 through fiscal year ended August 31, 2027, and the Company does not expect these provisions to have a material impact on our effective tax rate.

The provision for income taxes was 10.5% and 23.9% of income before income taxes for the fiscal years ended August 31, 2025 and 2024, respectively. The decrease in the effective income tax rate from period to period was primarily due to the expiration of the statute of limitations on the uncertain tax position associated with the Tax Cuts and Jobs Act’s mandatory one-time “toll tax” on unremitted foreign earnings. The release of the uncertain tax position generated a favorable income tax adjustment of $11.9 million, net of the tax effect of the related interest during twelve months ended August 31, 2025.

Reconciliations of the beginning and ending amounts of the Company’s gross unrecognized tax benefits, excluding interest and penalties, are as follows (in thousands):

Gross unrecognized tax benefits totaled $0.9 million and $9.1 million for the fiscal years ended August 31, 2025 and 2024, respectively, of which $0.7 million and $9.0 million, respectively, would affect the Company’s effective income tax rate if recognized. Interest and penalties related to uncertain tax positions included in tax expense was a benefit of $4.4 million for the fiscal year ended August 31, 2025 and an expense of $1.2 million for the fiscal year ended August 31, 2024. The total balance of accrued interest and penalties related to uncertain tax positions was insignificant and $4.6 million for the fiscal years ended August 31, 2025 and 2024, respectively. Total unrecognized tax benefits including interest and penalties were $1.1 million and $13.7 million as of August 31, 2025 and 2024, respectively, and are recorded in other long-term liabilities in the Company’s consolidated balance sheets.

The Company is subject to taxation in the U.S. and in various state and foreign jurisdictions. Due to expired statutes and closed audits, the Company’s federal income tax returns for years prior to fiscal year 2022 are not subject to examination by the U.S. Internal Revenue Service. The Company is currently under audit in various state jurisdictions for fiscal years 2022 through 2024. Generally, for the majority of state and foreign jurisdictions where the Company does business, periods prior to fiscal year 2021 are no longer subject to examination. The Company has estimated an amount of unrecognized tax

benefits, including interest and penalties, related to income tax positions may be affected by the resolution of tax examinations or expiring statutes of limitation within the next twelve months to be insignificant. Audit outcomes and the timing of settlements are subject to significant uncertainty.

Income taxes receivable of $4.9 million and $0.5 million are recorded in the Company’s consolidated balance sheets as of August 31, 2025 and 2024, respectively. Income taxes receivable are included in other current assets, which also consists of miscellaneous prepaid expenses and deposits.

Note 16. Stock-based Compensation

As of August 31, 2025, the Company had one stock incentive plan, the WD-40 Company 2016 Stock Incentive Plan (the “2016 Plan”), which was approved by the Company’s stockholders effective as of December 13, 2016 and which was amended and restated on December 12, 2023. The 2016 Plan permits the granting of various stock-based equity awards, including non-qualified stock options, incentive stock options, stock appreciation rights, restricted stock, restricted stock units, performance shares, performance units and other stock-based awards to employees, directors and consultants. To date through August 31, 2025, the Company had granted awards of restricted stock units (“RSUs”), market share units (“MSUs”), deferred performance units (“DPUs”) and performance share units (“PSUs”) under the 2016 Plan. Additionally, as of August 31, 2025, there were still certain outstanding awards which had been granted under the Company’s prior stock incentive plan. The 2016 Plan is administered by the Board or the Compensation and People Committee or other designated committee of the Board (the “Committee”). All stock-based equity awards granted under the 2016 Plan are subject to the specific terms and conditions as determined by the Committee at the time of grant of such awards in accordance with the various terms and conditions specified for each award type per the 2016 Plan. As of August 31, 2025, 973,514 shares of common stock remained available for future issuance pursuant to grants of awards under the 2016 Plan. The shares of common stock to be issued pursuant to awards under the 2016 Plan may be authorized shares not previously issued, or treasury shares. The Company has historically issued new authorized shares not previously issued upon the settlement of the various stock-based equity awards under its equity incentive plans.

Vesting of the RSUs granted to nonemployee directors is over a period of up to one year from the date of grant, with shares to be issued pursuant to the vested RSUs upon termination of each nonemployee director’s service as a director of the Company. Vesting of the RSUs granted to certain high level employees is over a period of three years from the date of grant, subject to potential earlier vesting in the event of retirement of the holder of the award in accordance with the award agreement, with shares to be issued pursuant to the vested RSUs at the time of vest. The nonemployee director RSU holders are entitled to receive dividend equivalents with respect to their vested RSUs, payable in cash as and when dividends are declared by the Board.

Vesting of the MSUs granted to certain high level employees follows a performance measurement period of three fiscal years commencing with the Company’s fiscal year in which the MSU awards are granted (the “Measurement Period”). Shares will be issued pursuant to the vested MSUs following the conclusion of the applicable MSU Measurement Period after the Committee’s certification of achievement of the applicable performance measure for such awards and the vesting of the MSU awards and the applicable percentage of the target number of MSU shares to be issued. The recipient must remain employed with the Company for vesting purposes until the date on which the Committee certifies achievement of the applicable performance measure for the MSU awards, subject to potential pro-rata vesting in the event of earlier retirement of the holder of the award in accordance with the award agreement.

During fiscal year 2021, PSU awards were granted for the first time under the 2016 Plan in October 2020 and granting of new DPUs was discontinued by the Company. No DPUs were granted in or after fiscal year 2021. Although certain vested DPU awards granted in prior periods remain outstanding due to a deferred settlement feature contained within these award agreements, the expense associated with these awards has been fully recognized in prior periods. Many features of the Company’s PSU award agreements are similar to the discontinued DPU awards with the exception of the timing and terms of issuances. Vested DPUs contain a deferred settlement feature wherein the awards must be held until termination of employment, prior to which the recipients are entitled to dividend equivalents, with vested shares to be issued six months following each such recipient’s separation from service from the Company. Vested PSUs are issuable prior to separation from service but contain a period of restriction, wherein the recipient cannot sell or otherwise dispose of the stock until six months following separation from service from the Company. Vesting of the PSUs granted to certain high level employees follows a performance measurement period of one fiscal year that is the same fiscal year in which the PSU awards are granted (the “Measurement Year”). A number of PSUs equal to the applicable percentage of the maximum number of PSUs awarded will be confirmed as vested and issuable following the conclusion of the applicable PSU Measurement Year after the Committee’s certification of achievement of the applicable performance measure for such awards. The recipient

must remain employed with the Company for vesting purposes until August 31 of the Measurement Year, subject to potential pro-rata vesting in the event of earlier retirement of the holder of the award in accordance with the award agreement.

Stock-based compensation expense is amortized on a straight-line basis over the requisite service period for the entire award. Stock-based compensation expense related to the Company’s stock-based equity awards is as follows by award type (in thousands):


	Fiscal Year Ended August 31,
	2025		2024		2023
RSU compensation expense	$	4,273	$	3,612	$	4,254
MSU compensation expense	3,033		2,282		2,180
PSU compensation expense (1)	—		641		—
Total	$	7,306	$	6,535	$	6,434

(1)PSU awards contain performance conditions for which accrual of expense is based on the probable outcome of the performance conditions. PSUs pertaining to the measurement year of fiscal year 2024 vested at 16.3% since the performance conditions were partially achieved. Vesting of PSUs pertaining to the measurement years of fiscal years 2025 and 2023 was deemed not probable at the end of each respective fiscal year and the PSUs were subsequently forfeited.

The Company recorded deferred tax assets related to such stock-based compensation of $1.7 million, $1.4 million and $1.3 million for the fiscal years ended August 31, 2025, 2024 and 2023, respectively. As of August 31, 2025, the total unamortized compensation cost related to non-vested stock-based equity awards was $1.7 million and $4.2 million for RSUs and MSUs, respectively, which the Company expects to recognize over remaining weighted-average vesting periods of 1.58 and 1.84 years for RSUs and MSUs, respectively. No unamortized compensation cost for DPUs or PSUs remained as of August 31, 2025.

Restricted Stock Units

The estimated fair value of each of the Company’s RSU awards was determined on the date of grant based on the closing market price of the Company’s common stock on the date of grant for those RSUs which are entitled to receive dividend equivalents with respect to the RSUs, or based on the closing market price of the Company’s common stock on the date of grant less the grant date present value of expected dividends during the vesting period for those RSUs which are not entitled to receive dividend equivalents with respect to the RSUs.

A summary of the Company’s restricted stock unit activity is as follows (in thousands, except share and per share amounts):


Restricted Stock Units	Number of Units	Weighted-Average Grant Date Fair Value Per Unit		Aggregate Intrinsic Value
Outstanding at August 31, 2024	70,148	$	164.03
Granted	18,522	253.47

Vested at August 31, 2025	35,354	$	181.66	$	7,638

The weighted-average grant date fair value of all RSUs granted was $253.47, $206.85 and $167.05 during the fiscal years ended August 31, 2025, 2024 and 2023, respectively. The total intrinsic value of all RSUs converted to shares of common stock was $6.3 million, $6.7 million and $3.7 million for the fiscal years ended August 31, 2025, 2024 and 2023, respectively.

The income tax benefits from RSUs converted to shares of common stock totaled $1.5 million, $1.3 million and $0.8 million for the fiscal years ended August 31, 2025, 2024 and 2023, respectively.

Market Share Units

The MSUs are market performance-based awards that vest with respect to the applicable percentage of the target number of MSU shares based on relative total stockholder return (“TSR”) for the Company as compared to the total return for the Russell 2000® Index (the “Index”) over the performance Measurement Period. The ultimate number of MSUs that vest may range from 0% to 200% of the original target number of shares depending on the relative achievement of the TSR performance measure at the end of the Measurement Period. The grant date fair value of MSUs are estimated using a Monte Carlo simulation model and are expensed over the requisite service period rendered. Assumptions and estimates utilized in the model include expected volatilities of the Company’s stock and the Index, the Company’s risk-free interest rate and expected dividends. The probabilities of the actual number of MSUs expected to vest and resultant actual number of shares of common stock expected to be awarded are reflected in the grant date fair values of the various MSU awards; therefore, the compensation expense for the MSU awards is not adjusted based on the actual number of such MSU awards to ultimately vest.

The following weighted-average assumptions for MSU grants for the last three fiscal years were used in the Monte Carlo simulation model:


	Fiscal Year Ended August 31,
	2025		2024		2023
Expected volatility	33.2	%	34.4	%	37.5	%
Risk-free interest rate	3.6	%	4.8	%	4.3	%
Expected dividend yield	0.0	%	0.0	%	0.0	%
Term	2.91 years		2.90 years		2.89 years

The expected volatility utilized is based on the historical volatilities of the Company’s common stock and the Index in order to model the stock price movements. The volatility used was calculated over the periods presented in the above table which were the remaining terms of the performance Measurement Period at the dates of grant. The risk-free interest rates used are based on the implied yield available on a U.S. Treasury zero-coupon bill with a remaining term equivalent to the remaining performance Measurement Period. The expected dividend yield of zero was used in the Monte Carlo simulation model for the purposes of computing the relative TSR of the Company compared to the Index since it is the mathematical equivalent to reinvesting dividends in each issuing entity over the performance Measurement Period.

A summary of the Company’s market share unit activity is as follows (in thousands, except share and per share amounts):


Market Share Units	Number of Units	Weighted-Average Grant Date Fair Value Per Unit		Aggregate Intrinsic Value
Outstanding at August 31, 2024	36,634	$	213.13
Granted	14,233	281.09
Performance factor adjustments	1,941	230.88
Converted to shares of common stock	(11,631)	230.90
Forfeited	(338)	195.69
Outstanding at August 31, 2025⁽¹⁾	40,839	$	232.74	$	8,823

(1)This figure represents the total number of shares underlying MSU grants assuming achievement of the target number of shares at 100%. As the ultimate number of shares that vest could be as high as 200% of the target, the Company may be required to issue additional shares to satisfy outstanding MSU award grants.

The weighted-average grant date fair value of all MSUs granted was $281.09, $226.30 and $184.15 during the fiscal years ended August 31, 2025, 2024 and 2023, respectively. The total intrinsic value of all MSUs converted to shares of common stock was $3.1 million for the fiscal year ended August 31, 2025.

Performance Share Units

The PSU awards provide for performance-based vesting over a measurement period of the fiscal year in which the PSU awards are granted. The performance vesting provisions of the PSUs are based on relative achievement within an established performance measure range of the Company’s reported earnings before interest, income taxes, depreciation in operating departments, and amortization computed on a consolidated basis for the Measurement Year, before deduction of the stock-based compensation expense for the Vested PSUs and excluding other non-operating income and expense amounts (“Adjusted Global EBITDA”). The ultimate number of PSUs that vest may range from 0% to 100% of the original maximum number of PSUs awarded depending on the relative achievement of the Adjusted Global EBITDA performance measure at the end of the Measurement Year.

The estimated fair value of each of the Company’s PSU awards was determined on the date of grant based on the closing market price of the Company’s common stock on the date of grant less the grant date present value of expected dividends during the vesting period for the PSUs, which are not entitled to receive dividend equivalents with respect to the unvested PSUs.
