"Fiscal year 2026 demonstrated the resilience of our business and the strength of our execution," said Steve Brass, president and chief executive officer of WD-40 Company. “We grew net sales 11%, grew maintenance product sales at the top of our long-term target range, and delivered results in line with guidance. Our globally decentralized supply chain continued to be a competitive advantage, helping us navigate volatility, deliver exceptional customer service and generate cost savings.

"Our fourth quarter financial results reflect higher input costs and continued investment in our people and brands. Higher costs for specialty chemicals and other inputs pressured gross margin. Based on what we know today, we believe our fourth quarter of fiscal year 2026 marked the low point for gross margin, and we anticipate sequential improvement beginning in the first quarter of fiscal year 2027. Selling, general and administrative expenses increased primarily due to performance-based incentive compensation earned by every employee, along with higher freight costs to keep products available for customers. Higher advertising and sales promotion expenses supported sales growth and brand building.
"We manage WD-40 Company for the long term. We see significant remaining opportunity for WD-40® Brand around the world and a long runway for growth. A resilient business model, durable competitive advantages, strong cash flow generation and disciplined capital allocation give us confidence in our ability to deliver sustainable growth and create long-term value for stockholders. Most importantly, our people turn that opportunity into results, and their commitment, capability and passion make our business stronger every year," concluded Brass.

•Net sales of maintenance products, the Company’s primary strategic focus, represented 96% of total net sales in the fourth quarter.

•Net sales of homecare and cleaning products represented 4% of total net sales in the fourth quarter. Net sales of homecare and cleaning products decreased 18% compared to the prior year quarter. The decrease primarily reflects the Company's divestiture of its entire homecare and cleaning products portfolio in the United Kingdom during the fourth quarter of fiscal year 2025. Net sales related to these products were $2.0 million in the prior-year period.
Dividend and Share Repurchase Update
•On October 8, 2026, the Board of Directors declared a quarterly cash dividend of $1.02 per share. The dividend is payable on October 30, 2026, to stockholders of record at the close of business on October 19, 2026.
