R. Tony Tripeny is a declared insider at 4 companies (finance chief); the most frequent names are Origin Materials, Inc., Corning INC /ny and Mesa Laboratories Inc /CO/. We count 31 filings; the first trade dates from 4 January 2016 and the latest from 15 August 2026.
The open-market record is one-sided, with 5 purchases worth €451k and not one sale. Unlike grants, an open-market purchase is paid for by the insider, at the market price. Outside the open market, there are 16 share grants and 10 option exercises. In 2026 alone, the filings show 3 purchases and no sales.
A typical purchase (the median) is worth €89k. 4 out of 5 purchases came within 30 days of a purchase by at least one other insider of the same company. When several insiders buy within a few weeks of each other, analysts speak of a cluster purchase.
The latest filing, published on 17 August 2026, reports an option exercise in Mesa Laboratories Inc /CO/. The last purchase on record was published on 17 August 2026, which is 61 days ago. The median gap between a trade and its publication by SEC (Form 4) is 2 days. The legal deadline for a Form 4 is two business days after the transaction. This summary is built from SEC (Form 4) disclosures alone and does not predict where the share price will go.
