About this page

Every figure above is derived from filings made with the US Securities and Exchange Commission: Form N-PX, in which registered funds disclose how they voted every proxy and institutional managers disclose their votes on executive pay (say-on-pay, say-on-frequency and golden parachutes), and Form 8-K Item 5.07, in which the company reports its own meeting results. Shares outstanding are taken from MARINUS PHARMACEUTICALS INC.’s 10-Q dated May 3, 2024. This page is a static snapshot rebuilt weekly on October 14, 2026; a live search always shows the current data.

At MARINUS PHARMACEUTICALS INC.'s shareholder meeting held May 22, 2024, in the 2023-2024 proxy season, 121 asset managers reported how they voted on 6 ballot items in their SEC Form N-PX filings, covering 786 separate fund positions. On the most widely held item on that ballot — Approval, on a non-binding advisory basis, of the compensation of the Company's named executive… — MARINUS PHARMACEUTICALS INC.'s filing reports the proposal as approved, with 78% support of the votes cast (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).
