Item 5.02. Departure of Directors or Certain Officers; Election of Directors; Appointment of Certain Officers; Compensatory Arrangements of Certain Officers.

On June 26, 2025, at the Annual Meeting of Stockholders (the “Annual Meeting”) of CoStar Group, Inc. (the “Company” or “our”), the stockholders of the Company, upon the recommendation of the Board of Directors of the Company (the “Board”), approved the CoStar Group, Inc. 2025 Stock Incentive Plan (the “2025 Plan”), which was approved by the Board on April 28, 2025 (the “Effective Date”), subject to stockholder approval. The 2025 Plan, among other things, permits the grant of stock options, stock appreciation rights, restricted stock and restricted stock units to employees, officers, consultants and directors of the Company and its subsidiaries. The 2025 Plan replaces the CoStar Group, Inc. 2016 Stock Incentive Plan (the “2016 Plan”), and no further grants will be made pursuant to the 2016 Plan. The number of shares of Company common stock that will be available for grant under the 2025 Plan will be the sum of (i) any shares that remained available for grant under the 2016 Plan as of the Effective Date, plus (ii) shares subject to outstanding awards under the 2016 Plan as of the Effective Date that are later forfeited.

A more detailed description of the material terms of the 2025 Plan was included in the Company’s Definitive Proxy Statement on Schedule 14A (“Proxy Statement”) filed with the Securities and Exchange Commission on April 30, 2025. The foregoing and the summary in the Proxy Statement are not complete summaries of the terms of the 2025 Plan and are qualified by reference to the text of the 2025 Plan, which is included as Exhibit 10.1 hereto and is incorporated by reference herein.
