CoStar Group, Inc. (NASDAQ: CSGP) filed a Form 8-K summarizing the results of its 26 June 2025 Annual Meeting of Stockholders. The central item was approval of the new 2025 Stock Incentive Plan, which replaces the 2016 plan and aggregates (i) the remaining share reserve from the prior plan and (ii) any shares that become available through future forfeitures of 2016-plan awards. The plan authorizes stock options, SARs, restricted stock and RSUs for employees, officers, directors and consultants, potentially enlarging the company’s long-term equity compensation pool and modestly diluting existing shareholders.
All eight director nominees—Louise S. Sams, Andrew C. Florance, John L. Berisford, Angelique G. Brunner, Rachel C. Glaser, John W. Hill, Christine M. McCarthy and Robert W. Musslewhite—were re-elected with strong majorities (votes for ranged from 364.7 million to 377.0 million).
Shareholders also:
- Ratified Ernst & Young LLP as independent auditor for FY 2025 (367.4 m for / 18.6 m against).
- Approved the non-binding say-on-pay resolution by a narrow 53.8% majority (202.8 m for / 174.3 m against).
- Rejected a shareholder proposal requesting increased political-spending transparency (124.2 m for / 251.4 m against).
No earnings data, acquisitions or other material transactions were disclosed. Exhibit 10.1 contains the full 2025 Stock Incentive Plan; inline XBRL cover data is furnished as Exhibit 104.
