Jeanmarie F. Desmond (senior executive) discloses dealings in 3 companies, chiefly Trinseo PLC, IPG Photonics Corp and Sylvamo Corp. Over a trading history stretching from 25 May 2021 to 14 May 2026, the count stands at 26 filings.

Both buying and selling appear: 2 purchases worth €52k, against 3 sales worth €319k. On balance, insiders were net sellers of €267k. Open-market purchases are the filings investors watch most closely, because the insider pays for the shares out of pocket. Besides market trades, the filings include 20 share grants. Since January 2026: no purchases and 1 sale on the market.

The record was last updated on 15 May 2026 with an open-market sale (€153k) in IPG Photonics Corp. The latest purchase dates back some time: it was published 1,131 days ago, on 13 September 2023. 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. Keep in mind that insiders sell for many reasons unrelated to the outlook, from tax bills to estate planning. Every figure here comes from the filings published by SEC (Form 4) and describes the past, not future prices; it is not investment advice.
