CoStar Group Inc expanded its revenue by 19% in 2025, driven primarily by acquisitions including Matterport and Domain Holdings Australia, which broadened its commercial and residential real estate data offerings. Despite topline growth reaching $3.2 billion, operating income turned negative due to increased amortization, personnel costs, and integration expenses tied to its recent acquisitions. The company maintains strong operating cash flow and a solid capital structure, supporting an aggressive share repurchase program totaling $1.5 billion authorization. Going forward, growth hinges on successful integration of new assets, supply chain stability for Matterport hardware, and residential market conditions.
