CoStar Group Q3 Revenue Increases 20% Year-over-Year, Net New Bookings up 92% Year-over-Year to $84 Million

ARLINGTON, Va.--( BUSINESS WIRE)--CoStar Group, Inc. (NASDAQ: CSGP), a leading provider of online real estate marketplaces, information, analytics, and 3D digital twin technology in the property markets, announced today that revenue for the quarter ended September 30, 2025 was $834 million, up 20% over revenue of $693 million for the quarter ended September 30, 2024. Net loss was $31 million and net loss per diluted share was $0.07 for the third quarter of 2025. Non-GAAP net income rose to $97 million in Q3, up 10% year-over-year. Non-GAAP net income per share was $0.23 in Q3, up 6% year-over-year. Adjusted EBITDA was $115 million in Q3 2025, an increase of 51% from Q3 2024.

“We had an outstanding Q3 2025 as we delivered our 58 th consecutive quarter of double-digit revenue growth with a 20% year-over-year 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 dedicated Homes.com sales team achieved its best net new bookings quarter. We continued our strong momentum in adding Homes Members in Q3 and today have over 26,000 Members, up nearly 150% since the end of Q3 2024. We added 7,000 Members in Q3. We have sold 3,300 Boosts to homeowners and agents since July. We delivered a 47% profit margin for Q3 2025 for our commercial information and marketplace businesses, 1 an increase of 400 basis points sequentially from Q2 2025, as well as year-over year compared to Q3 2024. We are hard at work integrating our two recent acquisitions of Domain and Matterport across CoStar.”

Florance continued, “I am extremely excited about the launch of Smart Search on Homes.com. Using proprietary AI and natural language capabilities designed by our engineers and developers, Smart Search lets consumers use their own voice to precisely search for a home. This allows for complex queries, such as long conversational phrases with multi-geographies and points of interest. In August, we launched Community Boost, which is our New Homes Builder membership. New bookings are off to a solid start. The Homes.com Network is the second largest in the industry in the United States, with 115 million average monthly unique visitors. 2”

1 References to “commercial information and marketplace businesses” refer to our consolidated financial position and results excluding the impact of Homes.com, OnTheMarket, Domain, and Matterport.

2025 Outlook

“We delivered strong revenue growth and adjusted EBITDA growth well ahead of our guidance, in this quarter," said Christian Lown, CFO of CoStar Group. The Company now expects revenue in the range of $3.23 billion to $3.24 billion for the full year of 2025, representing revenue growth of approximately 18% year-over-year at the midpoint of the range. The Company expects revenue for the fourth quarter of 2025 in the range of $885 million to $895 million, representing revenue growth of approximately 25% year-over-year at the midpoint of the range.

The Company is increasing its adjusted EBITDA guidance for the full year 2025 to a range of $415 million to $425 million, an increase of $40 million at the midpoint of the range from its previous guidance. For the fourth quarter 2025, the Company expects adjusted EBITDA in the range of $150 million to $160 million.

The Company expects full year 2025 non-GAAP net income per diluted share in a range of $0.82 to $0.84 based on 420 million shares. For the fourth quarter of 2025, the Company expects non-GAAP net income per diluted share in a range of $0.26 to $0.28 based on 424 million shares. These ranges include an estimated non-GAAP tax rate of 26% for the full year and the fourth quarter 2025.

The preceding forward-looking statements reflect CoStar Group’s expectations as of October 28, 2025, including forward-looking non-GAAP financial measures on a consolidated basis, based on current estimates, expectations, observations, and trends. Given the risk factors, rapidly evolving economic environment, and uncertainties and assumptions discussed in this release and in our quarterly reports on Form 10-Q and annual reports on Form 10-K, actual results may differ materially. Other than in publicly available statements, the Company does not intend to update its forward-looking statements until its next quarterly results announcement.

Reconciliations of EBITDA, adjusted EBITDA, non-GAAP net income, and non-GAAP net income per diluted share to the most directly comparable GAAP measures are shown in detail below, along with definitions for those terms. A reconciliation of forward-looking non-GAAP guidance to the most directly comparable GAAP measure, net income (loss), can be found within the tables included in this release.

Non-GAAP Financial Measures

For information regarding the purpose for which management uses the non-GAAP financial measures disclosed in this release and why management believes they provide useful information to investors regarding the Company’s financial condition and results of operations, please refer to the Company’s latest periodic report.

EBITDA is a non-GAAP financial measure that represents GAAP net income attributable to CoStar Group before interest income or expense, net and other income or expense, net; loss on debt extinguishment; income taxes, and depreciation and amortization expense.

Adjusted EBITDA is a non-GAAP financial measure that represents EBITDA before stock-based compensation expense; acquisition- and integration-related costs; restructuring and related costs, including certain advisory fees; and settlements and impairments incurred outside the Company’s ordinary course of business. Adjusted EBITDA margin represents adjusted EBITDA divided by revenues for the period.

Non-GAAP net income is a non-GAAP financial measure determined by adjusting GAAP net income (loss) attributable to CoStar Group for stock-based compensation expense; acquisition- and integration-related costs, including gains or losses on equity investments acquired in prospective targets and related to deal-contingent financial instruments; restructuring costs; settlement and impairment costs incurred outside the Company's ordinary course of business, and loss on debt extinguishment, as well as amortization of acquired intangible assets and other related costs, and then subtracting an assumed provision for income taxes. In 2025, the Company is assuming a 26% tax rate to approximate its statutory corporate tax rate, excluding the impact of discrete items, to determine Non-GAAP net income for each quarterly period, year-to-date period, and the annual period.

Non-GAAP net income per diluted share is a non-GAAP financial measure that represents non-GAAP net income divided by the number of diluted shares outstanding for the period used in the calculation of GAAP net income per diluted share. For periods with GAAP net losses and non-GAAP net income, the weighted average outstanding shares used to calculate non-GAAP net income per share includes potentially dilutive securities that were excluded from the calculation of GAAP net income per share as the effect was anti-dilutive.

Operating Metrics

Net new bookings is calculated based on the annualized amount of change in the Company's sales bookings resulting from new subscription-based contracts, changes to existing subscription-based contracts, and cancellations of subscription-based contracts for the period reported. Information regarding net new bookings is not comparable to, nor should it be substituted for, an analysis of the Company's revenues over time.

Earnings Conference Call

Management will conduct a conference call to discuss the third quarter 2025 results and the Company’s outlook at 5:00 PM ET on Tuesday, October 28, 2025. A live audio webcast of the conference will be available in listen-only mode through the Investors section of the CoStar Group website: https://investors.costargroup.com. A replay of the webcast audio will also be available in the Investors section of our website for a period of time following the call.

(1) Recorded in other expense, net in the condensed consolidated statements of operations.

(2) Totals may not foot due to rounding.

(3) The assumed tax rate approximates our statutory federal and state corporate tax rate for the applicable period.

(4) Diluted loss per share includes the effect of potential common shares, such as the Company's stock options, restricted stock units, and deferred stock units, to the extent the effect is dilutive. In periods with a net loss available to common stockholders, the anti-dilutive effect of these potential common shares is excluded and diluted net loss per share is equal to basic net loss per share. Non-GAAP weighted average shares have been adjusted for these periods to include the dilutive impact.
