 Costar Group posts mixed Q3 results, raises full-year outlook

ARLINGTON, Va. - Costar Group, Inc. (NASDAQ:CSGP) reported third-quarter revenue of $833.6 million, exceeding analyst expectations of $812.12 million and representing a 20% increase from $693 million in the same period last year. However, the company posted adjusted earnings per share of $0.23, beating its own guidance but falling short of the analyst consensus of $0.30.

The real estate marketplace and analytics provider reported a net loss of $31 million, or -$0.07 per share, for the quarter ended September 30, 2025. Non-GAAP net income rose 10% year-over-year to $97 million. Adjusted EBITDA reached $115 million, marking a substantial 51% increase from the third quarter of 2024.

The company’s stock remained flat in after-hours trading following the mixed results.

"We had an outstanding Q3 2025 as we delivered our 58th consecutive quarter of double-digit revenue growth with a 20% YoY increase in revenue," said Andy Florance, Founder and Chief Executive Officer of CoStar Group. "We achieved net new bookings in the third quarter of $84 million, up 92% year-over-year."

The company highlighted strong momentum in its residential segment, with Homes.com adding 7,000 new members in the quarter, bringing the total to over 26,000 members - a nearly 150% increase since Q3 2024. The commercial information and marketplace businesses delivered a 47% profit margin, up 400 basis points both sequentially and YoY.

CoStar raised its full-year 2025 guidance, now expecting revenue between $3.23 billion and $3.24 billion, representing approximately 18% growth at the midpoint. The company also increased its adjusted EBITDA guidance to a range of $415 million to $425 million, up $40 million at the midpoint from previous guidance.

For the fourth quarter, CoStar expects revenue between $885 million and $895 million, slightly below analyst estimates of $898.1 million, and adjusted EPS of $0.26 to $0.28, compared to the consensus of $0.30.
