CoStar Group, Inc. (NASDAQ: CSGP), a leading provider of online real estate marketplaces, information, and analytics in the property markets, announced today that revenue for the year ended December 31, 2024 was $2.74 billion, up 11% over revenue of $2.46 billion for the full year of 2023. Revenue for the fourth quarter of 2024 was $709 million, an increase of 11% over revenue of $640 million for the fourth quarter of 2023. Net income was $139 million for the year ended December 31, 2024, compared to $375 million for the year ended December 31, 2023, and net income was $60 million for the fourth quarter of 2024.

In February 2025, the Board of Directors of CoStar Group approved a stock repurchase program which authorizes, but does not obligate, the repurchase of up to $500 million of the Company’s common stock. The program has no time limit and can be discontinued at any time at the Company’s discretion.

“CoStar Group delivered another strong year of profitable revenue growth in 2024 and in the fourth quarter of 2024 we achieved our 55th consecutive quarter of double-digit revenue growth while exceeding the top-end of our guidance range in both revenue and Adjusted EBITDA,” said Andy Florance, Founder and Chief Executive Officer of CoStar Group. “Full year 2024 revenue grew 11% compared to 2023 as Net Income, EBITDA and Adjusted EBITDA increased significantly throughout 2024. In 2024, Apartments.com achieved $1.07 billion in revenue, growing 17% compared to 2023. CoStar, our flagship offering, generated revenue of $1.02 billion and grew 10% year-over-year. CoStar Group's commercial information and marketplace brands1 delivered exceptional results with 43% profit margins for 2024. CoStar Group delivered a 17% increase year-over-year in average monthly unique visitors to 134 million in the fourth quarter of 2024 according to Google Analytics.”

Florance continued, “In less than one year, the Homes.com Network has become the second largest residential real estate marketplace in the United States. We reached an audience of 110 million average monthly unique visitors in the fourth quarter, nearly doubling Realtor.com's 62 million average monthly unique visitors2. Homes.com is benefiting consumers, sellers and their agents. Consumers are using what we believe is the best site in the U.S. to find a home. Homes.com Members are gaining more exposure for their listings across the internet that helps them sell homes faster while building their brands and winning 58% more listings3. Our dedicated sales force has grown to 275 representatives with increasing productivity of tenured reps and rising customer NPS scores.”

2025 Outlook

The Company expects revenue in the range of $2.985 billion to $3.015 billion for the full year of 2025, representing year-over-year growth of approximately 10% at the midpoint of the range. The Company expects revenue for the first quarter of 2025 in the range of $711 million to $716 million, representing revenue growth of approximately 9% year-over-year at the midpoint of the range.

“We expect adjusted EBITDA for the full year of 2025 in the range of $375 to $405 million, a margin of 13% at the midpoint of the range. For the first quarter of 2025, we expect adjusted EBITDA in the range of $25 million to $35 million,” said Chris Lown, CFO of CoStar Group.

The preceding forward-looking statements reflect CoStar Group’s expectations as of February 18, 2025 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. Annualization of historical results from short periods of time or small sample sizes may differ materially from actual results realized in future periods and may not take into account other future market conditions that may negatively affect those results. 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 and adjusted EBITDA 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, 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; depreciation and amortization.

Adjusted EBITDA is a non-GAAP financial measure that represents EBITDA before stock-based compensation expense, acquisition- and integration-related costs, restructuring costs, 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.

Earnings Conference Call

Management will conduct a conference call to discuss the fourth quarter and full year 2024 results and the Company’s outlook at 5:00 PM ET on February 18, 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.

Such statements are based upon the current beliefs and expectations of management of CoStar Group and are subject to many risks and uncertainties. Actual results may differ materially from the results anticipated in the forward-looking statements and the assumptions and estimates used as a basis for the forward-looking statements. The following factors, among others, could cause or contribute to such differences: our inability to attract and retain new clients; our inability to successfully develop and introduce new or upgraded information, analytics, and online marketplace services; our inability to compete successfully against existing or future competitors in attracting advertisers and in general; the effects of fluctuations and market cyclicality; the effects of global economic uncertainties and downturns or a downturn or consolidation in the real estate industry; our inability to hire qualified persons for, or retain and continue to develop our sales force, or unproductivity of our sales force; our inability to retain and attract highly capable management and operating personnel; the downward pressure that our internal and external investments may place on our operating margins; our inability to increase brand awareness; our inability to maintain or increase internet traffic to our marketplaces, and the risk that the methods, including Google Analytics, that we use to measure average monthly unique visitors to our portals may misstate the actual number of unique persons who visit our network of mobile applications and websites for a given month or may differ from the methods used by competitors; our inability to attract new advertisers; our inability to successfully identify, finance, integrate, and/or manage costs related to acquisitions; our inability to complete certain strategic transactions if a proposed transaction is subject to review or approval by regulatory authorities pursuant to applicable laws or regulations; our inability to complete the acquisition of Matterport, Inc. (“Matterport”) or otherwise realize the benefits of the pending Matterport acquisition; the effects of cyberattacks and security vulnerabilities, and technical problems or disruptions; the significant costs associated with undertaking a large infrastructure project to build out our campus in Richmond, Virginia; our inability to generate increased revenues from our current or future geographic expansion plans; the risks related to acceptance of credit cards and debit cards and facilitation of other customer payments; the effects of climate related events and other events beyond our control; the effects related to attention to environmental, social and governance matters; our inability to obtain and maintain accurate, comprehensive, or reliable data; our inability to obtain and maintain stable data feeds, or disruption of our data feeds; our inability to enforce or defend our ownership and use of intellectual property; the effects of use of new and evolving technologies, including artificial intelligence, on our ability to protect our data and intellectual property from misappropriation by third parties; our inability to defend against potential legal liability for collecting, displaying, or distributing information; our inability to obtain or retain listings from real estate brokers, agents, property owners, and apartment property managers; our inability to maintain or establish relationships with third-party listing providers; our inability to comply with the rules and compliance requirements of Multiple Listing Services; the risks related to international operations; the effects of foreign currency exchange rate fluctuations; our indebtedness; the effects of a lowering or withdrawal of the ratings assigned to our debt securities by rating agencies; the effects of any actual or perceived failure to comply with privacy laws and standards; the effects of changes in tax laws, regulations, or fiscal and tax policies; the effects of third-party claims, litigation, regulatory proceedings, or government investigations; and risks related to return on investment.
