Ranked separately for each type of Form N-PX report. An institutional manager can report shares that a fund it advises also reports, so the two tables can list the same shares and are never added together. Each is ranked by the shares voted on the item that the most managers of that type reported, shown as a share of the 151,009,462 shares outstanding at the time of that meeting.

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 SERES THERAPEUTICS INC.’s 10-K dated March 1, 2024. This page is a static snapshot rebuilt weekly on October 18, 2026; a live search always shows the current data.

At SERES THERAPEUTICS INC.'s shareholder meeting held April 4, 2024, in the 2023-2024 proxy season, 112 asset managers reported how they voted on 7 ballot items in their SEC Form N-PX filings, covering 865 separate fund positions. On the most widely held item on that ballot — Approval, on an advisory (non- binding) basis, of the compensation of our named executive… — FOR was 65% 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), which is more than half. Whether the item was approved is for the filing to say; that statement has not been read for this item.
