CoStar Group Q2 2026 Results Mark a Profitability Inflection with Revenue Up 18%, Net Income Increasing 817%, and Adjusted EBITDA More Than Doubling Year-over-Year

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 June 30, 2026 was $925 million, up 18% over revenue of $781 million for the quarter ended June 30, 2025. Net new bookings were $69 million, up 3% from Q1 2026.

Net income was $55 million and earnings per diluted share was $0.14 for the second quarter of 2026, compared with net income of $6 million, and earnings per diluted share of $0.01, in the prior year period. Adjusted Net Income rose to $128 million in the second quarter, up 73% year-over-year. Adjusted EPS was $0.32 in the second quarter, up 88% year-over-year. EBITDA was $157 million, up 441% year-over-year. Adjusted EBITDA was $184 million in the second quarter of 2026, an increase of 116% from the prior year.

“The second quarter marked a profitability inflection point for CoStar Group as Adjusted EBITDA more than doubled year-over-year to $184 million. We held operating cost growth to just 2%, and we delivered our 61st consecutive quarter of double-digit revenue growth,” said Andy Florance, Founder and Chief Executive Officer of CoStar Group. “For the first time, our residential segment turned Adjusted EBITDA positive — a $41 million improvement over the first quarter — and we expect to deliver the highest full-year Adjusted EBITDA in our company’s history.”

Florance continued, “We continue to capture more of CoStar Group’s $100 billion total addressable market through new product launches and geographic expansion. Building on February’s transformative launch of Homes.com Ai, we introduced Apartments.com Ai in June. Within weeks, Apartments.com Ai users completed more than half a million AI sessions — averaging 20 minutes per session, 2.8 times longer than non-AI users, viewing twice as many listings, with 3D tour usage up 224% and traffic-to-lead conversion up 256%. Our product roadmap extends these AI capabilities across CoStar, LoopNet, and our international businesses. This quarter we also delivered four major launches on our core CoStar platform — including CoStar Rent Benchmark, built from four million AI-abstracted lease agreements, and CoStar’s market entry into France. We accomplished all of this while reducing our projected expense base by roughly $100 million versus our original guidance, giving us a head start on our 2028 and 2030 Adjusted EBITDA targets.”

2026 Outlook

The Company is affirming its Adjusted EBITDA guidance for the full year of 2026 in a range of $780 million to $820 million, which represents an increase of $30 million at the midpoint of the range from its guidance in February 2026. For the third quarter of 2026, the Company expects Adjusted EBITDA in the range of $190 million to $210 million, representing a margin of 21% at the midpoint of the range.

The Company is revising its revenue guidance for 2026 to a range of $3.715 billion to $3.755 billion, representing revenue growth of approximately 15% year-over-year at the midpoint of the range. The Company expects revenue for the third quarter of 2026 in the range of $935 million to $945 million, representing revenue growth of approximately 13% year-over-year at the midpoint of the range.

The Company reaffirms its full year 2026 Adjusted EPS in a range of $1.32 to $1.39 based on 405 million shares. For the third quarter of 2026, the Company expects Adjusted EPS in a range of $0.31 to $0.34 based on 403 million shares. These ranges include an estimated non-GAAP tax rate of 26% for the full year and the third quarter of 2026.

The preceding forward-looking statements reflect CoStar Group’s expectations as of July 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 is our net income (loss) before interest income or expense, net, other income or expense, net, income taxes, depreciation, and amortization. We typically disclose EBITDA on a consolidated and on an operating segment basis in our earnings releases, investor conference calls, and filings with the SEC.

Adjusted EBITDA is different from EBITDA because we further adjust EBITDA for stock-based compensation expense, acquisition- and integration-related costs, restructuring and related costs, including certain advisory fees; and settlements and impairments incurred outside our ordinary course of business, including judgments. Adjusted EBITDA margin represents Adjusted EBITDA divided by revenues for the period.

Adjusted Net Income represents our net income (loss) adjusted 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 our ordinary course of business, including judgments and related, non-recurring interest; and amortization of acquired intangible assets and other related costs, and then subtracting an assumed provision for income taxes. In 2026, we are assuming a 26% tax rate to approximate our statutory corporate tax rate, excluding the impact of discrete items, to determine Adjusted Net Income for each quarterly period, year-to-date period and 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 GAAP earnings 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 second quarter 2026 results and the Company’s outlook at 5:00 PM ET on July 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.

⁽¹⁾ Recorded in other expense, net in the condensed consolidated statements of operations.
⁽²⁾The assumed tax rate approximates our statutory federal and state corporate tax rate for the applicable period.
⁽³⁾ Diluted earnings 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, the anti-dilutive effect of these potential common shares is excluded and earnings per share – diluted is equal to earnings per share – basic. In periods with GAAP net losses and Adjusted Net Income, the weighted average shares outstanding have been adjusted to include the dilutive impact on Adjusted EPS.
