TRINSEO PLC 2024-2025 Proxy Voting Records

At TRINSEO PLC's shareholder meeting held June 25, 2025, in the 2024-2025 proxy season, 75 asset managers reported how they voted in their SEC Form N-PX filings, covering 715 separate fund positions. Their filings are grouped here into 16 reported items; because filers word the same ballot item differently, that can be more than the number of items on the ballot. TRINSEO PLC's own Form 8-K tally for this meeting is published below, but no row in it could be matched to the most widely held item, so this page states no certified outcome for that item. On that item — TO APPROVE, ON AN ADVISORY BASIS, THE COMPENSATION PAID BY THE COMPANY TO ITS NAMED EXECUTIVE… — the reporting funds and managers cast 97% of the shares they voted in favour (FOR divided by FOR plus AGAINST plus WITHHELD; abstained and unvoted shares are excluded because neither took a side). Fund and manager reports are combined in it and may count the same shares twice: it adds fund reports to institutional-manager reports, which can cover the same shares. It is not the company's certified result.

How asset managers voted at the TRINSEO PLC 2024-2025 meeting

Each item below shows how the 75 asset managers that disclosed a TRINSEO PLC vote in their SEC Form N-PX filings actually voted. Share totals are the shares those managers' funds voted, summed across every fund they report. These are reported items, not a count of the ballot: fund filings describe one ballot item in different words. Two descriptions are shown as one item only on evidence — the same text (or one cut short of the other), the same director nominee, or a match to the same row of TRINSEO PLC’s own Form 8-K tally — never because they merely read alike. A description that could not be joined that way is listed on its own, so one ballot item can appear more than once.
