Donald A. Denkhaus: trading record in brief
This profile gathers the share dealings of Donald A. Denkhaus in Catalyst Pharmaceuticals, Inc., where the filings describe the role as board member. In total, 21 filings cover trades dated from 7 January 2016 to 15 July 2026.
Both buying and selling appear: 1 purchase, against 2 sales worth €633k. No amount is published for 1 filing, which the totals therefore leave out. 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 17 option exercises.
The record was last updated on 17 July 2026 with a transaction (€13.7M) in Catalyst Pharmaceuticals, Inc. The last purchase on record was published on 7 January 2016, which is 3,936 days ago. Filings reach the SEC (Form 4) feed a median of 2 days after the trade. The legal deadline for a Form 4 is two business days after the transaction. Selling is not necessarily a view on the stock: liquidity needs and diversification are common motives. This summary is built from SEC (Form 4) disclosures alone and does not predict where the share price will go.
