All filings by Sara Kathleen Hyzer on record concern WD 40 Co, in the capacity of finance chief. Between 13 April 2023 and 8 October 2026, the trades on record add up to 11 filings.

The open-market record is one-sided, with 4 purchases worth €158k and not one sale. Open-market purchases are the filings investors watch most closely, because the insider pays for the shares out of pocket. Other entries cover 7 share grants.

A typical purchase (the median) is worth €40k. Clusters matter here: 3 out of 4 purchases overlapped with buying by a colleague within 30 days. A cluster is several different insiders buying the same stock within a short window, a pattern studied more closely than a single purchase. Ninety days after publication, 3 purchases show a median change of +7.5%, with the price up in 100% of them. Past outcomes like these are no guarantee of what comes next.

The record was last updated on 13 October 2026 with a share grant in WD 40 Co. The last insider purchase was made public on 29 October 2025, 354 days ago. Between a trade and the moment it shows up on SEC (Form 4), the median delay is 2 days. The legal deadline for a Form 4 is two business days after the transaction. Every figure here comes from the filings published by SEC (Form 4) and describes the past, not future prices; it is not investment advice.
