CoStar Group (CSGP) shares have shown volatility but stayed largely range-bound over the past 30 days. After trading near the high-$20s in late September, the stock advanced toward the mid-$30s in mid-October only to give back most of those gains after the third-quarter report. The 30-day change sits at roughly 2.7%, as strong profitability numbers were tempered by concerns over net new bookings and a more cautious organic growth view.
The company posted record adjusted EBITDA and topped consensus on adjusted EPS, yet the market focused on the bookings shortfall. Management linked this to economic pressures and slower sales-force expansion. With a market capitalization in the low teens of billions, CSGP continues to serve as a useful indicator for demand in commercial and residential real estate data.
CoStar Group provides commercial and residential real estate information, analytics, and online marketplaces, with its main operations in the United States and smaller footprints in Canada, the United Kingdom, and Europe. The commercial side centers on the CoStar Suite subscription platform and the LoopNet listing marketplace. The residential side includes Apartments.com and Homes.com, recently expanded through the Zonda acquisition in August 2026 that brought single-family home data. Other businesses such as Matterport, BizBuySell, Ten-X, and CoStar Real Estate Manager round out the portfolio. High renewal rates, proprietary data sets, and strong brand positioning give the company pricing power and recurring revenue streams.
The third-quarter 2026 results stood out for their profitability gains. Revenue climbed 14% year over year to $952 million, while adjusted EBITDA doubled to a record $229 million. Net income reached $74 million, and adjusted EPS of $0.38 exceeded expectations. I also checked this using Tickeron’s AI Screener to see how the stock compares to others in the industry.
Investors zeroed in on the softer side of the report. Annualized net new bookings came in at $37 million, below internal targets, which management tied to economic conditions and slower sales-force growth. Total sales headcount fell about 10% year over year as the company shifts toward more experienced field professionals. Full-year revenue guidance was adjusted to a midpoint near $3.76 billion, incorporating roughly $60 million from Zonda but reflecting a slightly softer organic trajectory. On the brighter side, adjusted EBITDA guidance was lifted to a midpoint of about $830 million, pointing to roughly 22% margins, and further cost savings were identified. Segment performance included 13% growth at LoopNet and 50% at Homes.com, with continued progress at Matterport and BizBuySell despite soft housing and multifamily markets.
The main question going forward is whether CSGP can rebuild sales-force momentum and bookings while keeping margins on an upward path. Plans to expand capacity in 2027, decentralize recruiting, and link growth to compensation will be worth watching. Macro risks remain prominent, with high interest rates, weak home sales, and elevated multifamily vacancies creating a challenging environment. Zonda integration, the Homes.com ramp, and expansion in the U.K. and Australia will also influence results. Future bookings trends, renewal rates, margin progress toward the 2028 $1.25 billion target, and any guidance updates will help clarify the balance between cost control and growth investments.
