Percentages above are of 84,461,365 shares outstanding, as reported by SUTRO BIOPHARMA INC. on its Form 10-Q dated 2025-05-02 (see the filing on EDGAR). This is the count contemporaneous with the 2024-2025 meeting, so the percentages are the ones that were true then, not ones restated against today’s share count.
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 SUTRO BIOPHARMA INC.’s 10-Q dated 2025-05-02. This page is a static snapshot rebuilt weekly on 02 October 2026; a live search always shows the current data.
At SUTRO BIOPHARMA INC.'s shareholder meeting held 2025-06-06, in the 2024-2025 proxy season, 110 asset managers reported how they voted on 6 ballot items in their SEC Form N-PX filings, covering 758 separate fund positions. On the most widely held item on that ballot — TO APPROVE, ON A NON-BINDING, ADVISORY BASIS, THE COMPENSATION OF OUR NAMED EXECUTIVE OFFICERS. — FOR was 78% 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.
