Philip R. Martens: trading record in brief

Philip R. Martens (board member) discloses dealings in 3 companies, chiefly Graphic Packaging Holding Co, Trinseo PLC and Plexus Corp. The record holds 14 filings, for trades running from 26 January 2016 to 20 May 2026.

The open-market record consists of 2 sales worth €1.2M, with no purchase. Outside the open market, there are 11 share grants and 1 option exercise.

The record was last updated on 21 May 2026 with a share grant in Graphic Packaging Holding Co. 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. 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.
