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 COSTAR GROUP INC.’s 10-K dated December 31, 2024. This page is a static snapshot rebuilt weekly on October 13, 2026; a live search always shows the current data.

At COSTAR GROUP INC.'s shareholder meeting held June 26, 2025, in the 2024-2025 proxy season, 795 asset managers reported how they voted on 12 ballot items in their SEC Form N-PX filings, covering 9,858 separate fund positions. On the most widely held item on that ballot — Proposal to approve, on an advisory basis, the Company's executive compensation. — COSTAR GROUP INC.'s filing reports the proposal as approved, with 53.8% 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: COSTAR GROUP INC.'s Form 8-K, Item 5.07, filed with the U.S. Securities and Exchange Commission on June 27, 2025.
