David Philip Henry

David Philip Henry, listed as senior executive, appears in our data through filings on MKS Inc shares, published by SEC (Form 4). We count 44 filings; the first trade dates from 16 February 2021 and the latest from 20 February 2026.

Both buying and selling appear: 1 purchase worth €159k, against 4 sales worth €1.2M. Taken together, the sales exceed the purchases by €1.1M. A purchase on the market is a deliberate choice to commit personal money, which is why it draws more attention than a grant. Besides market trades, the filings include 9 share grants and 30 option exercises. Since January 2026: no purchases and 1 sale on the market.

On 23 February 2026 came the latest disclosure, an open-market sale for €444k in MKS Inc. The last insider purchase was made public on 8 November 2023, 1,080 days ago. The median gap between a trade and its publication by SEC (Form 4) is 1 day. US insiders must file a Form 4 within two business days of a trade. A sale on its own says little: insiders also sell to pay tax, fund a purchase or diversify. This summary is built from SEC (Form 4) disclosures alone and does not predict where the share price will go.
