Valued at $26.9 billion by market cap, CoStar Group, Inc. (CSGP) is a leading provider of commercial real estate information, analytics, and online marketplaces, offering property data and insights to brokers, investors, and property owners. The company operates popular platforms like Apartments.com, Homes.com, and LoopNet, combining high-traffic marketplaces with a subscription-based data business that generates predictable, recurring revenue.
The company is all set to release its first-quarter earnings for 2026 on Tuesday, Apr. 28, after the markets close. Ahead of the event, analysts expect CSGP to report a profit of $0.11 per share on a diluted basis, up 37.5% from $0.08 per share in the year-ago quarter. The company has consistently surpassed Wall Street’s EPS estimates in its last four quarterly reports.
For the current year, analysts expect CSGP to report EPS of $0.96, up 81.1% from $0.53 in fiscal 2025. Looking ahead, its EPS is expected to rise 41.7% year over year to $1.36 in fiscal 2027.
