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 Tectonic Therapeutic, Inc.’s 10-Q dated May 1, 2026. This page is a static snapshot rebuilt weekly on October 18, 2026; a live search always shows the current data.

At Tectonic Therapeutic, Inc.'s shareholder meeting held June 8, 2026, in the 2025-2026 proxy season, 135 asset managers reported how they voted on 4 ballot items in their SEC Form N-PX filings, covering 607 separate fund positions. On the most widely held item on that ballot — ADVISORY APPROVAL OF THE COMPENSATION OF THE COMPANY'S NAMED EXECUTIVE OFFICERS. — Tectonic Therapeutic, Inc.'s filing reports the proposal as approved, with 99.1% 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). Source: Tectonic Therapeutic, Inc.'s Form 8-K, Item 5.07, filed with the U.S. Securities and Exchange Commission on June 10, 2026.
