Joseph S. Koscinski

Joseph S. Koscinski (chief executive) discloses dealings in Ecovyst Inc. to SEC (Form 4). We count 25 filings; the first trade dates from 2 October 2017 and the latest from 4 March 2026.

Every open-market trade on record is a purchase: 3 purchases worth €174k, and no sale. Buying on the open market means paying the going price with one's own funds, a different act from receiving shares as pay. Besides market trades, the filings include 21 share grants and 1 option exercise.

Half of the purchases are above €48k and half below. On 3 out of 3 purchases, another insider of the same company was buying within the same 30 days. When several insiders buy within a few weeks of each other, analysts speak of a cluster purchase.

On 6 March 2026 came the latest disclosure, a share grant for €108k in Ecovyst Inc. The latest purchase dates back some time: it was published 808 days ago, on 6 August 2024. 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.
