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 March 31, 2026 was $897 million, up 23% over revenue of $732 million for the quarter ended March 31, 2025.

Net income was $3 million and earnings per diluted share was $0.01 for the first quarter of 2026, compared with a net loss of $15 million, or a loss per share of $0.04, in the prior year period. Adjusted Net Income rose to $94 million in the first quarter, up 49% year-over-year. Adjusted EPS was $0.23 in the first quarter, up 53% year-over-year. Adjusted EBITDA was $132 million in the first quarter of 2026, an increase of 100% from the prior year.

“CoStar Group produced $67 million in net new bookings in the first quarter of 2026, an increase of 20% year-over-year. We have delivered 60 consecutive quarters of consistent, double-digit revenue growth in a wide range of economic conditions,” said Andy Florance, Founder and Chief Executive Officer of CoStar Group. “We continue to deliver on our goal of significant Adjusted EBITDA expansion in 2026 and beyond. Our strong 100% year-over-year growth in Adjusted EBITDA exceeded our expectations and was 26% higher than the midpoint of our guidance range.”

Florance continued, “The successful launch of our transformative Homes.com AI application in February has contributed to a 119% increase in organic traffic in the first quarter compared to the prior year period. Customer engagement accelerated as we delivered our best-ever time on site, page views, and bounce rates. In the first quarter, we introduced Smart Search on Apartments.com, our natural language search feature, and the first AI-powered voice search in multifamily marketplaces. We have also continued our strong momentum in adding Homes.com members and today have 35,000, up more than 200% from the same period a year ago.”

2026 Outlook

“This quarter, we delivered strong revenue and Adjusted EBITDA growth as we exceeded the midpoint of our revenue guidance and exceeded the top-end of our Adjusted EBITDA guidance,” said Christian Lown, CFO of CoStar Group. The Company reaffirms revenue in the range of $3.78 billion to $3.82 billion for the full year of 2026, representing revenue growth of approximately 17% year-over-year at the midpoint of the range. The Company expects revenue for the second quarter of 2026 in the range of $922 million to $932 million, representing revenue growth of approximately 19% year-over-year at the midpoint of the range.

The Company is increasing its Adjusted EBITDA guidance for the full year of 2026 to a range of $780 million to $820 million, an increase of $30 million at the midpoint of the range from its previous guidance. For the second quarter of 2026, the Company expects Adjusted EBITDA in the range of $160 million to $180 million.

The Company now expects full year 2026 Adjusted EPS in a range of $1.32 to $1.39 based on 409 million shares. For the second quarter of 2026, the Company expects Adjusted EPS in a range of $0.27 to $0.30 based on 409 million shares. These ranges include an estimated non-GAAP tax rate of 26% for the full year and the second quarter of 2026.

The preceding forward-looking statements reflect CoStar Group’s expectations as of April 28, 2026, 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, Adjusted Net Income, and Adjusted EPS 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 represents GAAP net income (loss) 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 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.

Adjusted Net Income is 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 2026, the Company is assuming a 26% tax rate to approximate its statutory corporate tax rate, excluding the impact of discrete items, to determine Adjusted Net Income for each quarterly period, year-to-date period, and the annual period.

Adjusted EPS represents Adjusted Net Income divided by the number of diluted shares outstanding for the period used in the calculation of GAAP earnings per diluted share. For periods with GAAP net losses and Adjusted Net Income, the weighted average outstanding shares used to calculate Adjusted EPS includes potentially dilutive securities that were excluded from the calculation of EPS 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 first quarter 2026 results and the Company’s outlook at 5:00 PM ET on April 28, 2026. 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.
