How asset managers voted at the TRINSEO PLC 2023-2024 meeting

Each item below shows how the 147 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.

Percentages above are of 35,294,231 shares outstanding, as reported by TRINSEO PLC on its Form 10-Q dated 2024-05-03 (see the filing on EDGAR). This is the count contemporaneous with the 2023-2024 meeting, so the percentages are the ones that were true then, not ones restated against today’s share count.

About this page

Every figure above is derived from filings made with the US Securities and Exchange Commission: Form N-PX, in which registered investment companies and institutional managers disclose how they voted every proxy, and Form 8-K Item 5.07, in which the company reports its own meeting results. Shares outstanding are taken from TRINSEO PLC’s 10-Q dated 2024-05-03. This page is a static snapshot rebuilt weekly on 02 October 2026; a live search always shows the current data.

At TRINSEO PLC's shareholder meeting held 2024-06-26, in the 2023-2024 proxy season, 147 asset managers reported how they voted in their SEC Form N-PX filings, covering 2,280 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 cast 97% of the shares they voted in favour (FOR divided by FOR plus AGAINST, the conventional basis for proxy support; abstentions, broker non-votes and unvoted shares are excluded because none of them took a side). That is the aggregate of those managers' own N-PX disclosures, not the company's certified result, and the funds are a subset of all shareholders.
