How asset managers voted at the SIX FLAGS ENTERTAINMENT CORP. 2023-2024 meeting

Each item below shows how the 283 asset managers that disclosed a SIX FLAGS ENTERTAINMENT CORP. 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 SIX FLAGS ENTERTAINMENT CORP.’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.

1. The Compensation Advisory Proposal - To approve, on a non- binding advisory basis, the compensation that may be paid or become payable to Six Flags' named executive officers that is based on or otherwise relates to the Mergers (the "Compensation Advisory Proposal").

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 SIX FLAGS ENTERTAINMENT CORP.’s 8-K dated 2023-12-31. This page is a static snapshot rebuilt weekly on 02 October 2026; a live search always shows the current data.

At SIX FLAGS ENTERTAINMENT CORP.'s shareholder meeting held 2024-03-12, in the 2023-2024 proxy season, 283 asset managers reported how they voted in their SEC Form N-PX filings, covering 1,006 separate fund positions. Their filings are grouped here into 10 reported items; because filers word the same ballot item differently, that can be more than the number of items on the ballot. No official Form 8-K vote tally has been matched to this meeting, so this page states no certified outcome for its most widely held ballot item. On that item — The Compensation Advisory Proposal - To approve, on a non- binding advisory basis, the… — the reporting funds cast 40% 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.
