Valuation X-Ray

Asset, earnings-power and peer-multiple models all land far below the price; ONLY the growth-DCF reaches it. The bet is durable compounding the static frames structurally cannot price (a moat/durability premium).

How the valuation models price the stock relative to the market price. Price/FV above 1.0 means the market pays more than that lens defends (expensive); at or below 1.0 the lens can defend the price.

One or more material disclosed units has unresolved economics. Unknown/general is not evidence of homogeneity: segment SOTP is primary but incomplete, consolidated cash flow may remain only a secondary cross-check when every unit shares an enterprise basis, and one sector multiple or target margin is withheld.

Bullet Takeaways

Bull Case

The advantage here is easy to miss because it looks like a software business and behaves like a toll road. CoStar sells research nobody else has bothered to assemble: field researchers walking buildings, verifying leases, photographing space, then licensing the result back to the industry that generated it. The filing describes contracts that generally renew automatically, a majority of which have a term of at least one year, and states that Revenues from subscription-based contracts are approximately 93% of total revenues for the current year. Ninety-three percent contracted is not a software metric. It is closer to a utility bill.

The commercial side has kept compounding through a genuinely bad stretch for its customers. Commercial Real Estate revenue went from 1,443 million dollars in 2023 to 1,515 million in 2024 to 1,787 million in 2025, which is growth accelerating rather than fading, in a period when the brokerages that buy the data were cutting costs. Compare the customers: CBRE runs a 4.7% operating margin and JLL 4.4%. The information supplier is expanding while the transaction businesses it serves grind along at low single-digit margins, which is the clearest available evidence about where the pricing power sits.

What that model earns at maturity is visible in companies that already run it. MSCI posts a 55.4% operating margin and SPGI 43.9%, both selling subscription data into financial markets. CoStar's own through-the-cycle operating margin is about 17.7%, on a business that has been spending heavily to build a second franchise rather than harvesting the first. The bull case does not require CoStar to reach the margins MSCI and SPGI achieve. It requires only that the spending stops being open-ended, at which point a subscription base this contracted converts a large share of incremental revenue into profit.

Then there is the second business, which is the reason the stock is where it is. Residential revenue rose from 1,012 million dollars in 2023 to 1,221 million in 2024 to 1,460 million in 2025, so the audience is being bought successfully even if it is being bought expensively. The filing records acquisitions of OnTheMarket, Visual Lease, Matterport and Domain, with 994 million dollars of the goodwill from the Domain transaction allocated to the residential segment. Whatever else is true of that strategy, it has assembled residential listing platforms across the U.S., the U.K. and Australia in a few years, and the balance sheet carried it without strain: net cash of about 206 million dollars on the funded-debt measure, liquid assets near 1.22 billion, and interest covered better than 20 times. The company can afford to be wrong for a while. That is not nothing when the alternative is a rights issue.

Bear Case

The earnings this price is measured against are not the earnings the company reported. On a trailing basis the operating margin is about -3.6%, meaning CoStar lost money at the operating line, and the whole valuation case rests on replacing that figure with a through-the-cycle margin near 17.7% and treating the gap as a cyclical trough. Sometimes that is the right call. It is only the right call if the thing depressing the margin is the cycle rather than a decision.

Here it is a decision, and the filing puts a number on it. Residential Real Estate adjusted profitability, on the company's own segment measure, fell 317 million dollars to a loss of 361 million dollars for 2025. That is not a commercial property downturn showing up in the accounts. That is what happens when a company spends to buy an audience in a market where the incumbent has never made money either: ZG generates 2.69 billion dollars of revenue growing 16.8% and converts it into a 0.4% operating margin. If that is the mature state of a residential portal rather than an early one, then the through-the-cycle margin doing the work in the valuation belongs to only half the company, and the other half is a permanent subtraction from it.

The quality of the contracted base has also been drifting. The 10-K discloses that revenue from subscription-based contracts with a term of at least one year were approximately 76%, 81%, and 82% of total revenue across the three reported years. The direction is the wrong way. Headline subscription revenue stays near ninety-three percent of the total, but the share locked up for a year or more has fallen six points, which is what happens when growth arrives through marketplaces and acquisitions rather than through the research licence that made the company defensible.

The company also names the technological threat itself, and does so without hedging: rapid advancement of generative AI Technologies may reduce the barrier to entry for new competitors. A proprietary database of building-level facts is exactly the sort of asset whose replacement cost falls when machines get better at reading documents and images. Add the disclosed dependence on search ranking, where the filing concedes that maintaining prominent positioning is not entirely within our control, and the residential strategy has two upstream gatekeepers it does not own.

Cash flow shows the same story from a different angle. Free cash flow ran about 231 million dollars while stock-based compensation ran about 210 million, so nearly all of the cash the business produced was matched by pay issued in shares, and the count has risen about 1.2% a year over four years. The downside is bounded to a degree: roughly 308 million dollars of equity stakes sit outside the operating businesses. Against an 11.4 billion dollar market value, that boundary is close to decorative. The real floor is whether the commercial franchise, on its own, justifies what the market is paying for both.

Valuation

The first thing to settle is which year you are valuing. Trailing operating profit is negative, so every method built on the last twelve months is measuring a company that did not make money. The alternative is to normalize: use the margins the business has earned through the cycle rather than the trough it just posted, which gives a through-the-cycle operating margin near 17.7% against the roughly -3.6% actually reported on a trailing basis. On that normalized basis the market is paying about 19 times through-cycle operating income at $27.66, and inverting it gives a requirement of roughly 14.3% operating profit growth a year for five years. Treat that as one solve under fixed assumptions, not a measurement.

Two things about that requirement deserve attention. About 46% of comparable fast growers sustained a pace like it for that long, which is a coin flip rather than a long shot. But the answer is unusually sensitive to the discount rate: each additional percentage point of cost of capital moves the implied growth requirement by roughly 6.8 percentage points. A modest change in what investors demand from a mid-cap growth name transforms the assumption from ordinary to heroic, which is a fair description of why this stock has been repriced rather than re-rated.

The methods used to triangulate value split the way they usually do for a company earning nothing at the moment. The asset-based, earnings-power and peer-multiple approaches all land far below the current price, and only the forward-growth approaches reach it. That pattern normally signals a durability premium, and here it partly does. But the distance those static methods report is exaggerated by their inputs: each one is computed off a year with essentially no earnings, so a method dividing by profit produces a small number almost mechanically. The signal is the direction, not the magnitude.

Peers frame the destination rather than the current price. MSCI and SPGI, running the same subscription data model at maturity, earn operating margins of 55.4% and 43.9%. Those are the economics the commercial franchise is being credited with eventually reaching. Meanwhile ZG, operating the residential model CoStar is buying into, converts 16.8% revenue growth into a 0.4% operating margin. The valuation implicitly assumes the first comparison applies and the second does not.

The balance sheet keeps the clock running. Net cash of about 206 million dollars on the funded-debt measure, gross borrowings near 1.01 billion, liquid assets of about 1.22 billion, and interest covered better than 20 times: nothing here forces a decision. What it does not do is generate the return by itself, since the share count has grown about 1.2% a year over the past four years rather than shrinking. The buyer at today's price is funding a second business out of the first one's cash flow and taking the view that the spending has an end date.

Catalysts

The next report lands on July 28, 2026. It follows a 2025 in which revenue rose about 19% while reported earnings all but disappeared, so the useful disclosure will be the residential segment's loss trajectory rather than the consolidated top line. A narrowing loss there changes the normalization argument; a widening one changes it the other way.

Management is changing at the same time. CoStar announced the appointment of a new chief financial officer, Robin Rossmann, effective July 31, 2026. A finance chief arriving days after a print is generally the person who owns the following year's spending plan, which matters more than usual for a company whose central question is how long the residential investment runs.

The sell side moved against the stock in the same fortnight. Baird cut its rating to Neutral from Outperform on July 14, and RBC Capital, Keefe Bruyette and Goldman Sachs each reduced their price targets on July 13. On the operating side, the company launched its commercial platform in France on July 1, continuing an international build that has now added the U.K., Australia and continental Europe. Its own research arm reported that U.S. retail asking rent growth slowed in the second quarter of 2026, which is a demand signal for the customers who renew those subscriptions.
