Actionable Insight • Neutral

The compensation redesign and enhanced governance measures signal management responsiveness to activist and shareholder concerns, which may reduce overhang from the 2025 Say-on-Pay vote. The $1.5B buyback authorization and moderated Homes.com spending plan provide a clearer capital return framework. Monitor the June 23 annual meeting vote outcome, particularly the Say-on-Pay proposal, for signals on shareholder sentiment.

Executive Summary

CoStar Group filed supplemental DEFA14A proxy soliciting materials ahead of its June 23, 2026 annual meeting, detailing a comprehensive executive compensation redesign for 2026 in response to stockholder feedback and a 2025 Say-on-Pay vote. The redesign shifts to 80% PSUs for the CEO, eliminates stock options and tax gross-ups, increases CEO stock ownership guidelines to 10x base salary, and sets more rigorous quantitative goals. The filing also highlights board refreshment (4 new directors since 2023, including two activist designees from D.E. Shaw and Third Point), the formation of a Capital Allocation Committee, and a new $1.5 billion share repurchase program authorized in January 2026.
