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 Altimmune, Inc.’s 10-Q dated March 31, 2026. This page is a static snapshot rebuilt weekly on October 25, 2026; a live search always shows the current data.

At Altimmune, Inc.'s 2 shareholder meetings in the 2025-2026 proxy season (held September 25, 2025 and April 16, 2026), 186 asset managers reported how they voted on 27 ballot items in their SEC Form N-PX filings, covering 3,796 separate fund positions. On the most widely held item of the season, voted at the meeting held April 16, 2026 — HOLD AN ADVISORY VOTE ON THE COMPENSATION OF THE COMPANY'S NAMED EXECUTIVE OFFICERS AS… — FOR was 77% 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. Source: Altimmune, Inc.'s Form 8-K, Item 5.07, filed with the U.S. Securities and Exchange Commission on April 16, 2026.
