Windacre Partnership LLC: trading record in brief
This profile gathers the share dealings of Windacre Partnership LLC across 2 companies, led by Perimeter Solutions, SA and Nielsen Holdings plc. The record holds 11 filings, for trades running from 6 April 2022 to 30 June 2026.
The open-market side counts 3 purchases for €694.0M alongside 7 sales for €171.8M. Purchases outweigh sales by €522.1M. A purchase on the market is a deliberate choice to commit personal money, which is why it draws more attention than a grant. In 2026 alone, the filings show no purchases and 7 sales.
The median purchase comes to €250.3M. None of the 3 purchases we analysed coincided with buying by another insider of the same company within 30 days.
The latest filing, published on 13 July 2026, reports an open-market sale of €638k in Perimeter Solutions, SA. The last insider purchase was made public on 18 April 2022, 1,644 days ago. Between a trade and the moment it shows up on SEC (Form 4), the median delay is 14 days. Section 16 rules allow two business days to file each Form 4. A sale on its own says little: insiders also sell to pay tax, fund a purchase or diversify. This summary is built from SEC (Form 4) disclosures alone and does not predict where the share price will go.
