WD-40 is trading 4.36% down at $204.81 in pre-market, as no clear company-specific catalyst has emerged for August 26, 2026.
- The latest identifiable catalyst was a strong third-quarter earnings report and raised fiscal-year guidance announced July 9, making it unlikely to explain the decline.
- Recent company materials show no fresh major release.
- Broader U.S. index futures are only modestly weaker, leaving the immediate trigger unclear.
