CoStar Group Third Quarter 2023 Revenue Increased 12% Year-over-Year Marking 50 Straight Quarters of Double-Digit Revenue Growth

October 24, 2023

WASHINGTON--(BUSINESS WIRE)-- 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 quarter ended September 30, 2023 was $625 million, up 12% over revenue of $557 million for the quarter ended September 30, 2022. Net income was $91 million in the third quarter, an increase of 25% over the prior year.

“CoStar Group delivered strong results this quarter on our two principal fronts,” said Andy Florance, Founder and CEO of CoStar Group. “First, our commercial information and marketplace businesses are fortress strong in a turbulent market with revenue growing 14% year-over-year and margins approaching 40%. As we move into the fourth quarter, our adjusted EBITDA, for our commercial information and marketplace businesses, is approaching $1,000,000,000 annualized. We continue to generate strong net new bookings with $65 million of net new bookings in the third quarter. On the second front, we are investing aggressively, but prudently, in Homes.com with the goal of unlocking the enormous potential of becoming the leading, successful U.S. residential real estate portal. In September we celebrated a major milestone on that road to success with 100 million unique visitors to Homes.com.”

“Unique visitors to Homes.com in September grew 1,290% year over year, significantly outperforming our competitors’ traffic, the largest of which were relatively flat or declining. We believe that the competitive balance in the industry is shifting in our favor,” continued Florance. “Our key competitors' sites combine rentals and resale homes, so when we likewise combine our Homes.com and Apartments networks we had 140 million unique visitors in September, according to Google Analytics. In the past year we have quickly grown to become the second most heavily trafficked residential network by a wide margin, with monthly unique visitors 35% higher than Realtor.com and 90% higher than Redfin in September, according to ComScore. We continue to build out the full potential of Homes.com and are focused on continuing to grow traffic and beginning monetization in second quarter of 2024.”

“Last week, we announced our offer to acquire OnTheMarket, one of the top three residential property portals in the United Kingdom. Having operated successfully in the United Kingdom for two decades, we believe that we can grow competitive traffic share in the U.K. just as we have done so many times before in the U.S. and that our significant software investments into Homes.com will give us technology scale advantage in the U.K.”

2023 Outlook

The Company expects revenue in the range of $2.445 billion to $2.450 billion for the full year of 2023, representing year-over-year growth of approximately 12% at the midpoint of the range. The Company expects revenue for the fourth quarter of 2023 in the range of $630 million to $635 million, representing revenue growth of approximately 10% year-over-year at the midpoint of the range.

“Against one of the worst property markets in decades, we continue to demonstrate that our commercial information and marketplace businesses can deliver strong, double-digit revenue growth regardless of market cycles,” said Scott Wheeler, CFO of CoStar Group. “Our commercial information and marketplace business is expected to deliver 12% year-over-year revenue growth in the fourth quarter of 2023, and 14% revenue growth for the full year of 2023. Our Homes.com strategy is proving to be very successful and has moved us into second place in the U.S. We are wisely accelerating our investment in our residential marketplace in the second half of 2023. We now expect adjusted EBITDA for the full year of 2023 in the range of $485 million to $490 million. For the fourth quarter of 2023, we expect adjusted EBITDA in the range of $123 million to $128 million.”

The Company expects full year 2023 non-GAAP net income per diluted share in a range of $1.21 to $1.22 based on 407 million shares. For the fourth quarter of 2023, the Company expects non-GAAP net income per diluted share in a range of $0.31 to $0.32 based on 407 million shares. These ranges include an estimated non-GAAP tax rate of 26% for the full year and the fourth quarter of 2023.

The preceding forward-looking statements reflect CoStar Group’s expectations as of October 24, 2023, 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, 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.

Non-GAAP net income is a non-GAAP financial measure determined by adjusting GAAP net income attributable to CoStar Group for stock-based compensation expense, acquisition- and integration-related costs, 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 2023, the Company is assuming a 26% tax rate in order to approximate its statutory corporate tax rate excluding the impact of discrete items.

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 2023 results and the Company’s outlook at 5:00 PM ET on Tuesday, October 24, 2023. 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.
