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 Gossamer Bio, Inc.’s 10-Q dated May 12, 2026. This page is a static snapshot rebuilt weekly on October 14, 2026; a live search always shows the current data.
