WD-40 (WDFC) is scheduled to report fiscal Q4 2026 earnings after the close on October 21, with consensus estimates at $1.13 EPS and roughly $172 million in revenue. Traders’ slight lean toward a miss at 54% implied probability reflects the typical seasonal slowdown in the final quarter relative to the robust Q3 beat—where EPS of $2.33 and revenue of $195 million exceeded estimates by wide margins—along with mixed results across prior periods. Elevated input-cost volatility and a 30x trailing P/E multiple add caution, even as the company maintains a Moderate Buy rating and raised full-year guidance after Q3. The October 21 release and subsequent conference call represent the immediate catalyst that could shift positioning.
