CoStar Group Provides Full Year 2026 and Medium-Term Outlook with Significant Adjusted EBITDA Expansion

Key Terms

adjusted ebitda financial

Adjusted EBITDA is a way companies measure how much money they make from their core operations, like running a business, by removing certain costs or income that aren’t part of regular business activities. It helps investors see how well a company is doing without distractions from unusual expenses or gains, making it easier to compare companies or track performance over time.

share repurchase program financial

A share repurchase program is when a company buys back its own shares from the marketplace. This reduces the total number of shares available, which can increase the value of each remaining share and signal confidence in the company's prospects. For investors, it often suggests that the company believes its stock is undervalued or that it has extra cash to return to shareholders.

compound annual growth rate (cagr) financial

Compound annual growth rate (CAGR) shows how much an investment grows, on average, each year over a certain period. It’s like measuring how fast a plant grows each year, smoothing out the ups and downs to see the overall growth trend. Investors use CAGR to compare different investments and see which one has the best long-term performance.

net investment financial

Net investment is the amount of money a company or fund puts into buying or improving long-term assets after subtracting the proceeds from selling or disposing of assets — think of it as how much new value is added once old items sold are accounted for, like buying new furniture after selling the old pieces. For investors, it shows whether a business is expanding or shrinking its productive base, which affects future earnings potential, cash flow and the likely return on capital.

non-gaap net income financial

Non-GAAP net income is a company's profit figure that excludes certain costs or income that are included in standard accounting methods. Companies often use it to show what their earnings might look like without one-time expenses or other unusual items, helping investors see the company's core performance more clearly.

capital allocation committee financial

A capital allocation committee is a group of senior executives and board members who decide how a company should use its cash—such as investing in projects, buying back shares, paying dividends, or reducing debt. For investors it matters because these choices shape future growth and returns much like a household deciding whether to renovate, save, or pay off loans; smart allocation can boost long‑term value, while poor choices can erode it.

executive compensation program financial

A plan that determines how top managers are paid and rewarded, typically combining salary, bonuses, stock grants or options, and long-term incentive awards. Investors care because this pay package both affects a company’s costs and signals whether executives’ incentives are aligned with shareholder interests—like setting a coach’s bonus to team wins, it can motivate performance or create risky behavior if structured poorly.

proxy statement regulatory

A proxy statement is a document companies send to shareholders ahead of a meeting that lays out the items up for a vote—like who will sit on the board, executive pay, and major corporate decisions—and provides background so shareholders can decide how to cast their votes or appoint someone to vote for them. Think of it as an agenda plus a ballot and briefing notes, important because the outcomes can change control, strategy, and value.

Announces New $1.5 Billion Share Repurchase Program

Implements New Executive Compensation Program Responding to Stockholder Feedback

ARLINGTON, Va.--(BUSINESS WIRE)-- CoStar Group, Inc.

As a result of a robust review undertaken by the Capital Allocation Committee, the plan calls for significant expansion of Adjusted EBITDA. CoStar Group also announced the authorization of a new $1.5 billion share repurchase program.

Based on its results to date and the initiatives underway, the Company is providing the following outlook for 2026:

• Revenue: $3.78 billion to $3.82 billion, representing approximately 18% year-over-year growth over the midpoint of our previously provided 2025 guidance

• Adjusted EBITDA: $740 million to $800 million, the highest Adjusted EBITDA in Company history, representing a 20% margin at the midpoint, and 83% year-over-year growth over the midpoint of our previously provided 2025 guidance

Homes.com is an important component of our Residential portfolio which includes Apartments.com, Domain, OnTheMarket, and Land.com. Homes.com is experiencing rapid growth, with a 337% increase in subscribers since Q1 2024. The Company is implementing its proven playbook to continue to scale Homes.com and drive profitability. This includes lowering the capital intensity of Homes.com. CoStar Group intends to reduce net investment, revenue less directly attributable and allocated costs, by more than $300 million in 2026, down from $850 million in 2025. Moving forward, CoStar Group expects to continue to reduce net investment in Homes.com by $100+ million annually until 2030.

CoStar Group now expects Homes.com to:

• Deliver revenue in excess of expenses exiting 2029, supported by subscriber acquisition, in-depth advertising, builder partnerships, the Company’s Boost program, and continued reduction in expenses.
• Attain positive Adjusted EBITDA in 2030.
• Ultimately, CoStar Group expects Homes.com to be a strong contributor to Adjusted EBITDA and stockholder value.

“Building on our strong foundation, we continue to expand and evolve our platforms and increase the efficiency of our business model to accelerate profitability while growing the top-line,” said Andy Florance, Founder and Chief Executive Officer of CoStar Group. “We deliver unparalleled value to customers and extend our market-leading positions through our comprehensive ecosystem, underpinned by unmatched, integrated infrastructure and the world’s largest proprietary real estate information database. This positions CoStar Group to capture compelling near- and long-term growth with significant Adjusted EBITDA expansion for several years to come. Homes.com is an important part of our ecosystem; we now have a clear path to accelerate top-line growth and drive profitability. Through the deployment of our scalable AI platform and our disciplined capital allocation approach, we are well positioned to build on our strong trajectory and drive enhanced stockholder value.”

CoStar Group’s core business has strong momentum driven by its high-growth, high-margin subscription business model that continues to deliver excellent customer retention resulting in predictable and resilient revenue streams. The Company is taking action to accelerate progress in 2026, including the continued rollout of its comprehensive deployment of AI across CoStar Group to drive revenue growth and reduce costs. The Company has already achieved outstanding efficiencies through AI deployment – particularly in content creation, research of public records, writing code, and lease data extraction – the savings of which are included in the 2026 outlook provided today. Additionally, CoStar Group intends to make AI enhancements to the user experience on all marketplace platforms to extend its competitive advantages.

“The actions announced today are the result of a thorough, independent review by the Capital Allocation Committee and reflect the Board’s commitment to aligning capital allocation and executive compensation programs with the interests of all stockholders,” said Louise Sams, Independent Chair of the Board. “These updates follow robust engagement with stockholders over the last six months and implement the feedback we’ve received. The Board unanimously believes that CoStar Group is executing the right strategy to drive sustainable, profitable growth and is focused on holding management accountable to deliver on the Company’s objectives for the benefit of our stockholders.”

Increased Return of Capital to Stockholders

In alignment with CoStar Group’s commitment to disciplined and proactive return of capital to stockholders, the Capital Allocation Committee recommended, and the Board authorized, a new $1.5 billion repurchase of common stock.¹ This new authorization follows the Company’s accelerated completion of its $500 million share repurchase program in 2025. The Company continues to fund its organic growth primarily through capital generated from its businesses, maintaining ample liquidity to support its business strategy as well as returning capital to stockholders.

New Executive Compensation Program Responding to Stockholder Feedback

Following robust stockholder engagement and an extensive review, the Board’s Compensation Committee recommended, and the Board approved a redesigned executive compensation program for 2026. The new program features more rigorous (and more heavily quantitative) goals, enhanced transparency, and a simplified structure, with a focus on close alignment with stockholder interests. Additional information regarding the new executive compensation program will be available in the Company’s proxy statement for its 2026 Annual Meeting of Stockholders.

Forward-Looking Statements

The preceding forward-looking statements reflect CoStar Group’s expectations as of January 7, 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 Adjusted EBITDA, non-GAAP net income, and adjusted EPS or 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 Measure

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; 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.

Adjusted EPS or 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.

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.
