Matthew Lanigan (chief executive) discloses dealings in NPK International Inc. to SEC (Form 4). In total, 15 filings cover trades dated from 18 May 2021 to 3 October 2025.

The open-market record is one-sided, with 1 purchase worth €47k and not one sale. Buying on the open market means paying the going price with one's own funds, a different act from receiving shares as pay. The rest of the record consists of 2 share grants and 11 option exercises.

The record was last updated on 6 October 2025 with a transaction in NPK International Inc. The latest purchase dates back some time: it was published 1,531 days ago, on 9 August 2022. Between a trade and the moment it shows up on SEC (Form 4), the median delay is 3 days. For comparison, the SEC allows two business days to file a Form 4. This summary is built from SEC (Form 4) disclosures alone and does not predict where the share price will go.
