Robert F. Buesinger

All filings by Robert F. Buesinger on record concern Westlake Corp, in the capacity of senior executive. We count 29 filings; the first trade dates from 10 May 2021 and the latest from 27 March 2026.

The open-market side counts 1 purchase for €6,829 alongside 8 sales for €2.8M. Netting one side against the other leaves €2.8M of net selling. A purchase on the market is a deliberate choice to commit personal money, which is why it draws more attention than a grant. The rest of the record consists of 7 share grants and 11 option exercises. Since January 2026: no purchases and 1 sale on the market.

The newest entry dates from 31 March 2026: an open-market sale of €400k, in Westlake Corp. The last purchase on record was published on 9 June 2025, which is 496 days ago. Typically, a trade is published a median of 2 days after it takes place. Section 16 rules allow two business days to file each Form 4. Sales are harder to read than purchases, since they often meet personal needs such as tax or diversification. This summary is built from SEC (Form 4) disclosures alone and does not predict where the share price will go.
