Reports Q1 revenue $897M, consensus $896.7M. “CoStar Group (CSGP) produced $67 million in net new bookings in the first quarter of 2026, an increase of 20% year-over-year. We have delivered 60 consecutive quarters of consistent, double-digit revenue growth in a wide range of economic conditions,” said Andy Florance, CEO. “We continue to deliver on our goal of significant Adjusted EBITDA expansion in 2026 and beyond. Our strong 100% year-over-year growth in Adjusted EBITDA exceeded our expectations and was 26% higher than the midpoint of our guidance range. The successful launch of our transformative Homes.com AI application in February has contributed to a 119% increase in organic traffic in the first quarter compared to the prior year period. Customer engagement accelerated as we delivered our best-ever time on site, page views, and bounce rates. In the first quarter, we introduced Smart Search on Apartments.com, our natural language search feature, and the first AI-powered voice search in multifamily marketplaces. We have also continued our strong momentum in adding Homes.com members and today have 35,000, up more than 200% from the same period a year ago.”
