As a value investor, I look first for a business I can understand and a price that leaves room for error. WD-40 sells humble maintenance and cleaning products—aerosols, penetrants, degreasers, and the WD-40 Multi-Use brand—through much of the world with only 714 employees. In fiscal 2025, the year ended 2025-08-31, it produced $620.0M of revenue and $91.0M of net income. In fiscal Q3 2026, the quarter ended 2026-05-31, revenue was $195.1M versus $156.9M in fiscal Q3 2025, while net income rose to $30.2M from $21.0M and diluted EPS to $2.24 from $1.54. That is strong recent growth, and the balance sheet looks fortress-like: FairStock's Altman Z-Score is 10.15, debt-to-equity is 0.41, and Piotroski F-Score is 8/9. FairStock also calculates ROE of 33.31% and ROCE of 15.42%, signs of a high-return business. The likely moat is the WD-40 brand and global distribution, which support repeat business. But the price is the problem. At the 2026-10-13 close of $204.41, FairStock calculates a P/E of 31.07, P/B of 9.86, FCF yield of 2.9%, EV/EBITDA of 21.82, and a Graham Number of $55.41—a negative margin of safety of -268.90%. The dividend yield is 2.16%, and the PEG ratio of 0.71 offers some consolation if growth persists. FairStock classifies it as CYCLICAL—Specialty Chemicals because earnings follow the economic cycle. This is a fine business, but not a Graham bargain; the stock already discounts much of its quality and growth.

In plain English: WD-40 makes and sells WD-40 spray, cleaners, and maintenance products around the world. The business looks strong: sales and profits rose in the latest reported quarter, and it has little debt. But the stock price looks expensive compared with the company's earnings and balance sheet, so the good news may already be priced in.
