CoStar Group

CoStar Group runs real estate information and online marketplaces in two segments. Commercial Real Estate includes the CoStar data subscription, LoopNet and Matterport 3D digital twins. Residential Real Estate includes the Apartments.com network, Homes.com and, since 2025, Australia's Domain. 2025 revenue was $3.25 billion (+19%), but net income fell to $7 million because of heavy Residential marketing spend: the Residential segment's Adjusted EBITDA was −$230 million. In Q2 2026, Residential Adjusted EBITDA turned positive for the first time, according to CoStar. In 2025 it completed the Matterport and Domain acquisitions (about $3.9 billion combined), and in August 2026 it bought Zonda for $800 million.

    Revenue grew +14.4% a year over 5 years (strong growth)

    From $1.66B in FY2020 to $3.25B in FY2025. The annualized rate (CAGR) makes it possible to compare growth pace across companies of different sizes.

  • ▼

    Operating margin declined: 17.4% → -2.2%

    How much operating profit is left per $100 of revenue. It moved -19.6 points over 5 years — pricing power, cost control, and product mix all show up here.

  • ▲

    Equity ratio is 79.1% (a high level of financial stability)

    The share of total assets funded by equity rather than debt. 50%+ is often read as low bankruptcy risk, though the right level varies by industry (real estate and leasing run lower, for instance).

  • ―

    Free cash flow was positive in 5 of 6 years

    Operating cash flow minus capital expenditures: the cash left over after funding the business’s own investment, available for dividends, buybacks, acquisitions, or debt paydown. A negative year can mean heavy investment, or weak core earnings — worth distinguishing.

  • ▼

    ROE averaged 3.8% over 6 years (latest: 0.1%)

    How much profit was generated on shareholders’ equity. Roughly 10%+ is often cited as solid for a U.S. company, though this varies a lot by industry and capital intensity.

ROIC (the return on money invested in the business) above WACC (the cost of raising that money) means the company is creating value. WACC is an estimate, so its assumptions can be adjusted below.

ROIC (FY2025)

-0.6%

formulaoperating income × (1 − tax rate) ÷ invested capital × 100 *invested capital = interest-bearing debt + total equity (average of beginning/ending)

e.g.$-72M × (1 − 30%) ÷ $8,959M × 100 = -0.6%

termsOperating income · Effective tax rate · Invested capital · Interest-bearing debt · Total equity

WACC (this site’s estimate)

8.78%

formulacost of equity × equity weight + cost of debt × (1 − tax rate) × debt weight

e.g.Equity weight: $28.1B ÷ ($28.1B + $993M) = 96.6%

e.g.Debt weight: $993M ÷ ($28.1B + $993M) = 3.4%

e.g.WACC: 9.0% × 96.6% + 2.8% × (1 − 30%) × 3.4% = 8.78%

termsCost of equity · Equity weight (E/(D+E)) · Cost of debt · (1 − tax rate) · Debt weight (D/(D+E)) · Market capitalization

How firm is this? With the equity risk premium ±1 point and beta ±0.2, WACC runs 7.2%–10.7% and ROIC − WACC runs −11.3 to −7.8 points. The sign holds across this range. This describes the latest year and does not predict future value creation.

What the price implies (DCF)From SEC data

A company's value can be written as its free cash flow divided by (cost of capital − perpetual growth). Working that backwards from the market's valuation shows how much growth the share price assumed — compared here with the company's actual past growth.

Growth the price implies (price on 2026-11-04)

7.8%

Perpetual FCF growth: g = r − FCF ÷ EV = 8.8% − 0.9%

Past FCF growth (FY2020–FY2025)

-24.0%

Compound annual rate, 5 years

Past revenue growth (FY2020–FY2025)

+14.4%

Compound annual rate, 5 years

Inputs (FY2025): free cash flow $123M (operating CF − capex); enterprise value $13.15B = market cap $13.79B (latest close, 2026-11-04) + debt $993M − cash and short-term investments $1.63B; r = WACC of 8.8% using this page’s default assumptions (β 0.74, risk-free 5.0%, market premium 5.5%).

Three WACC scenarios

The same calculation under cautious, base and optimistic cost-of-capital assumptions (risk-free rate fixed at the 10-year Treasury yield). Pick one to load it into the sliders below.

Try your own assumptions

V = FCF ÷ (r − g). It starts at the implied growth rate, where the theoretical value equals today’s enterprise value.

Theoretical enterprise value

$12.3B

FCF $123M ÷ (8.8% − 7.8%)

Theoretical ÷ actual enterprise value

0.94x

Below 1x: these assumptions value the business below the market did

How sensitive the answer is

Theoretical ÷ actual enterprise value for each combination of r and g.

g \ r6.8%7.8%8.8%9.8%10.8%
0%0.14x0.12x0.11x0.10x0.09x

6%1.17x0.52x0.33x0.25x0.19x
8%——1.17x0.52x0.33x

A simplified model for seeing what the market price assumes, not a forecast or a target price. It treats free cash flow as growing at one constant rate forever; the result swings widely with small changes in r and g, and is undefined when g reaches r. Free cash flow here is operating cash flow minus capex, which is after interest — a full DCF of enterprise value would use cash flow before interest. Market cap uses the latest close (2026-11-04) × shares at fiscal year-end; free cash flow and WACC inputs are from the latest fiscal year.

  • If third-party suppliers upon which Matterport relies are not able to fulfill its needs, Matterport's ability to timely and cost effectively bring its hardware products to market could be affected.

  • Failure to comply with the terms of the underlying open source software licenses could restrict our ability to deliver our products or services or subject us to litigation or other action s .

  • We are expanding our operations outside of the United States, which may subject us to increased business, regulatory, and economic risks that could harm our business.

  • With respect to our products or services that incorporate AI Technologies, the market for such products and services is rapidly evolving and unproven in many industries, including our own, and important assumptions about the characteristics of targeted markets, pricing, sales cycles, cost, performance, and perceived value associated with our services or products may be inaccurate. Our failure to successfully develop and commercialize our products or services involving AI Technologies could harm our ability to expand our business; provide, improve and diversify our product offerings; continue our operations and efficiently manage our operating expenses; and respond effectively to competitive developments, which could adversely affect our business, results of operations, and financial condition.

  • If third-party suppliers upon which Matterport relies are not able to fulfill its needs, Matterport’s ability to timely and cost effectively bring its hardware products to market could be affected. Read more

    Matterport relies on a limited number of suppliers to supply its hardware components for its cameras and other hardware products, including in some cases only a single supplier for some products and components. This reliance on a limited number of manufacturers increases its risks, since Matterport does not currently have proven reliable alternative or replacement manufacturers beyond these key parties. In the event of interruption, we may not be able to increase capacity from other sources or develop alternate or secondary sources, and if such sources become available, they may result in material additional costs and substantial delays.

  • Unexpected changes in business conditions, materials pricing, labor issues, wars, trade policies, natural disasters, health epidemics, trade and shipping disruptions, port congestions, and other factors beyond our or our suppliers’ control could also affect these suppliers’ ability to deliver components to us or to remain solvent and operational. Such disruptions could adversely affect our business if we are not able to meet customer demands. In addition, some of our suppliers are located in China. Our access to suppliers in China may be limited or impaired as a result of tariffs, including those that have been recently introduced by the current U.S. administration, or other government restrictions in response to geopolitical factors. There is no guarantee we may be able to continually use alternative suppliers and alternative parts as we scale production to meet our growth targets.…

  • If we face supply constraints for any of the reasons described above, it may not be possible to obtain or increase supplies on acceptable terms, which may undermine our ability to satisfy customer demands in a timely manner. Read more

    For example, it may take a significant amount of time to identify a manufacturer that has the capability and resources to build and supply necessary hardware components in sufficient volume. Identifying suitable suppliers can be an extensive process that requires us to become satisfied with our suppliers’ quality control, technical capabilities, responsiveness and service, financial stability, regulatory compliance, and labor and other ethical practices. Accordingly, a loss of any significant suppliers or manufacturers would have an adverse effect on our business, financial condition, and operating results.
