Third Quarter Highlights and Summary:

•Total net sales were $156.9 million, an increase of 1 percent compared to the prior year fiscal quarter.

•Translation of the Company’s foreign subsidiaries’ results from their functional currencies to U.S. dollars had an unfavorable impact on net sales of approximately $1.6 million for the current quarter.

•Gross margin was 56.2 percent compared to 53.1 percent in the prior year fiscal quarter.

•Selling, general, and administrative expenses were $51.5 million, up 13 percent compared to the prior year fiscal quarter.

•Advertising and sales promotion expenses were $9.2 million, down 2 percent compared to the prior year fiscal quarter. These expenses accounted for 5.8 percent of total net sales, down from 6.0 percent in the prior year fiscal quarter.

•Operating income was $27.4 million, an increase of 1 percent from the prior year fiscal quarter.

•Net income was $21.0 million, an increase of 6 percent from the prior year fiscal quarter.

“Today we reported third quarter net sales of $156.9 million — a new record high for net sales in a quarter — reflecting a modest 1 percent year-over-year increase,” said Steve Brass, president and chief executive officer. “Our core maintenance products grew 2 percent in the quarter and are up 6 percent year-to-date, aligning with our long-term growth objectives. At the same time, we’ve made significant progress on gross margin recovery, reaching 56 percent in the third quarter — an improvement of 310 basis points over last year. We now expect to exceed our 55 percent long-term gross margin target for the fiscal year 2025, a full year ahead of schedule. While we remain mindful of external risks, we’re confident in our trajectory and our ability to deliver on the measures that drive long-term value creation for our stockholders.”

•The Americas segment represented 50 percent of total net sales in the third quarter.

•Total net sales in the Americas increased 4 percent in the third quarter compared to the prior year fiscal quarter primarily due to a 5 percent increase in net sales of WD-40® Multi-Use Product. WD-40® Multi-Use Product sales increased most significantly in the United States, which increased $3.0 million compared to the prior year fiscal quarter. Sales growth in the United States was largely attributable to increased promotional activity and the timing of customer orders. These increases were slightly offset by lower sales of WD-40® Multi-Use Product in Canada, which were down $0.2 million due to changes in distribution and reduced promotional activity. Sales in Latin America remained constant.

•Net sales of WD-40 Specialist® increased $0.4 million, or 4 percent, compared to the prior year fiscal quarter primarily due to expanded distribution in the United States.

•Translation of the Company’s foreign subsidiaries’ results from their functional currencies to U.S. dollars had an unfavorable impact on net sales in the Americas of approximately $1.8 million for the current quarter.

•The EIMEA segment represented 36 percent of total net sales in the third quarter.

•Total net sales in EIMEA decreased 5 percent in the third quarter compared to the prior year fiscal quarter primarily due to a 6 percent decrease in net sales of WD-40® Multi-Use Product. WD-40® Multi-Use Product sales decreased $2.6 million resulting from a decrease in sales volume in the EIMEA distributor markets, primarily in Turkey and the Middle East. This was driven by the timing of customer orders as well as operational changes in the region. These decreases were partially offset by increases in most of the EIMEA direct markets.

•Net sales of WD-40 Specialist® increased $1.3 million, or 15 percent, compared to the prior year fiscal quarter primarily due to higher sales volume as a result of increased promotional activity for our WD-40 Specialist® Bike product line in the DACH region, as well as stronger levels of demand in France and other direct markets.

•Translation of the Company’s foreign subsidiaries’ results from their functional currencies to U.S. dollars had a favorable impact on net sales in EIMEA of approximately $0.4 million for the current quarter.

•The Asia-Pacific segment represented 14 percent of total net sales in the third quarter.

•Total net sales in Asia-Pacific increased 7 percent in the third quarter compared to the prior year fiscal quarter primarily due to a 10 percent increase in sales of WD-40® Multi-Use Product. WD-40® Multi-Use Product sales increased by $0.9 million in China and by $0.6 million in the Asia distributor markets. The growth in China was due to successful promotional programs and expanded distribution. The growth in the Asia distributor markets was driven by successful promotional programs and increased demand, particularly in Indonesia and Taiwan.

•Net sales of WD-40 Specialist® increased 6 percent primarily due to higher sales volume from successful promotional programs and marketing activities in the Asia distributor markets and China.

•Homecare and cleaning product sales, which remain a strategic focus for the Company in Australia, decreased 8 percent due to reduced promotional activity and the timing of customer orders.

•Translation of the Company’s foreign subsidiaries’ results from their functional currencies to U.S. dollars had an unfavorable impact on net sales in Asia-Pacific of approximately $0.2 million for the current quarter.

•Net sales of maintenance products, which are considered the primary strategic focus for the Company, represented 96 percent of total net sales in the third quarter. Net sales of maintenance products increased 2 percent in the third quarter compared to the prior year fiscal quarter primarily due to higher sales of WD-40® Multi-Use Product in the United States and certain Asia-Pacific regions such as China and the Asia distributor markets.

•Net sales of homecare and cleaning products represented 4 percent of total net sales in the third quarter. Net sales of homecare and cleaning products decreased 17 percent in the third quarter compared to the prior year fiscal quarter. The Company has announced its intent to sell its homecare and cleaning product portfolios in the Americas and United Kingdom.

•On June 17, 2025, the Company’s board of directors declared a regular quarterly dividend of $0.94 per share payable on July 31, 2025 to stockholders of record at the close of business on July 18, 2025.

•On June 16, 2025, the Company’s board approved an 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. The Company is currently authorized to acquire up to $50.0 million of its outstanding shares through the expiration date of August 31, 2026, of which $32.2 million remains available for the repurchase of shares of common stock as of May 31, 2025.

•During the period from September 1, 2024 through the end of the third quarter, the Company repurchased 39,000 shares at a total cost of $9.7 million.

•The timing and amount of repurchases under the plan are based on terms and conditions as may be acceptable to the Company’s chief executive officer and chief financial officer, subject to present loan covenants, and in compliance with all laws and regulations applicable thereto.

The Company updated the following fiscal year guidance. This guidance is on a pro forma basis, excluding the full fiscal year financial impact of certain homecare and cleaning products classified as assets held for sale and the impact of the previously disclosed uncertain tax position benefit.

•Net sales growth from the pro forma 2024 results has been narrowed to be projected to be between 6 and 9 percent, with net sales between $600 million and $620 million, after adjusting for estimated translation impacts of foreign currency.

•Gross margin for the full year continues to be expected to be between 55 and 56 percent.

•Advertising and promotion investments continues to be projected to be around 6 percent of net sales.

•Operating income has been increased to be projected to be between $96 million and $101 million. This range now reflects anticipated growth of between 7 to 12 percent compared to 2024 pro forma results.

•The provision for income tax continues to be expected to be around 22.5 percent.

•Diluted earnings per share have been increased and are now expected to be between $5.30 and $5.60 based on an estimated 13.5 million weighted average shares outstanding. This new range reflects anticipated growth of between 12 to 18 percent compared to 2024 pro forma results.

This guidance is expressed in good faith and is based on management’s current view of anticipated results on a pro forma basis. Unanticipated inflationary headwinds, foreign currency exchange fluctuations, changes in trade tariffs, and other unforeseen events may further affect the Company’s financial results. Net sales guidance is adjusted for estimated translation impact of foreign currency use weighted average fiscal year 2024 foreign currency exchange rates. In the event the Company is unsuccessful in the divestiture of its assets currently held for sale, its guidance would be positively impacted by approximately $20 million in net sales, approximately $6 million in operating income, and approximately $0.33 in diluted EPS for the full fiscal year.
