How asset managers voted at the MKS INSTRUMENTS INC. 2023-2024 meeting

Each item below shows how the 385 asset managers that disclosed a MKS INSTRUMENTS INC. 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 MKS INSTRUMENTS INC.’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.

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. This page is a static snapshot rebuilt weekly on 02 October 2026; a live search always shows the current data.

At MKS INSTRUMENTS INC.'s shareholder meeting held 2024-05-07, in the 2023-2024 proxy season, 385 asset managers reported how they voted in their SEC Form N-PX filings, covering 3,365 separate fund positions. Their filings are grouped here into 11 reported items; because filers word the same ballot item differently, that can be more than the number of items on the ballot. MKS INSTRUMENTS INC.'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 — The approval, on an advisory basis, of executive compensation. — the reporting funds cast 99.1% 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.
