What Happened?
CoStar Group (CSGP) spent a year defined by an activist fight. With that gone, the market has found a new worry, and it came from inside the building. On July 13, the company said Chief Financial Officer Christian Lown would step down on July 31 to pursue something outside real estate, with Europe chief Robin Rossmann taking over. The next day, shares fell about 4% to a fresh low near $28. Within hours, two research desks moved: Baird pulled its Outperform rating to Neutral and cut its target to $34, while RBC kept its Sector Perform call but trimmed its target to $34.
The timing is what makes it awkward. All of it landed roughly two weeks before second-quarter results on July 28, and management did not reaffirm guidance on the way out. A finance chief leaving right before a print is the kind of gap a nervous market fills with its own worst assumptions. The stock has fallen 59% in 2026 and about 68% over the past year, sitting closer to its 52-week low of $26.68 than to any recovery.
CoStar plainly looks cheap. What is unresolved is whether the fear driving it lower points at something real, or whether it has widened an already large gap between price and underlying value.
The Departure Baird Could Not Get Comfortable With
Read the two notes side by side, and the disagreement is narrower than the headlines suggest. Baird’s downgrade rested on one thing: the CFO left, and management did not use the moment to reaffirm the near-term outlook, which lowered the firm’s confidence into the quarter. Baird also flagged net new bookings, soft for several quarters, including the first quarter for both the core business and Homes.com. It did not call the business broken, only a lower-conviction idea when other beaten-down peers look just as cheap with fewer question marks.
RBC’s note runs almost the opposite way. The firm modeled second-quarter net new bookings of roughly $82 million, slightly below the Street, with revenue about in line and adjusted EBITDA and earnings per share pushing toward the high end of guidance. RBC even expects a full-year reaffirmation. Its lower target reflects a tougher multiple, 18 times 2027 estimated earnings versus 21 times before, not a lower earnings forecast. The debate is about confidence and timing, not whether the money is there. Even after the cuts, the current $44 street mean, which already reflects this month’s downgrades, sits well above the price.
The CFO’s news is a voluntary departure, the company said, which was not tied to any disagreement over operations, policies, or practices. It is not a guidance cut and not a restatement. Rossmann is no outside unknown: over two years running Europe, he stripped out roughly $51 million of cost, about a quarter of that region’s base, while the business still grew double digits and launched CoStar in France. Management is framing his promotion around margin expansion, the one thing this stock most needs to prove.

The Quarter That Turned Residential Around
The last reported quarter was strong where it counts. First-quarter 2026 revenue was $897 million, up 23% year over year, the 60th straight quarter of double-digit growth, and adjusted EBITDA of $132 million doubled from a year earlier while landing 26% above the midpoint of guidance.
The freshest signal was residential, the segment that has scared investors for two years. It improved by $56 million year over year, and management guided it to swing from a negative $29 million in the first quarter to somewhere between breakeven and positive $10 million in the second. That guided inflection is the single most important number in the July 28 report.
What underpins the residential case is pricing power that the market has not credited. On the first 11,400 Homes.com members, CEO Andy Florance said the average subscriber “earned $36,400 more in commissions in their first year as a member” against a $3,400 subscription cost. The company began raising new-customer fees on May 1 on the strength of that data. Whether the pricing holds as it scales past 35,000 agent subscribers is the open question the next few quarters will answer.
A Business Adding a $1 Trillion Market While the Stock Falls
The strangest part of the current price is what the company has been doing while it drops. On May 29, CoStar signed a definitive agreement to acquire Zonda, the leading new-home construction data and marketplace business, for $800 million in cash. Announced after the first-quarter call and expected to close in the second half of 2026, it pushes CoStar into homebuilding, a segment the company notes carries an annual construction value approaching $1 trillion. Zonda brings more than 3,000 customers, 104% net customer retention, and the NewHomeSource and Livabl marketplaces. It is an announced agreement still subject to regulatory clearance, not a closed deal, and it has already drawn antitrust attention from at least one advocacy group worried about data concentration.
Against peers, CoStar trades at about 13.7 times next-twelve-months EV/EBITDA, close to CBRE Group at 13.2 times and Altus Group at 12.4 times. On revenue, the picture flips: CoStar sits at 3.09 times NTM enterprise value to revenue versus CBRE at just 1.05 times, a premium justified by its 78.6% gross margin against a brokerage’s thinner economics. That premium holds only as long as the margin expansion arrives. If Homes.com keeps consuming cash past management’s timelines, the premium compresses first.

TIKR’s mid-case scenario, realized at the end of 2030, values CoStar at around $66, roughly 120% above today’s $29.68, or about 20% per year. Two revenue drivers carry it: continued double-digit growth in the commercial data franchise, where quarterly renewal runs at 92%, and CoStar users grew 22% year over year, and the scaling of residential through Apartments.com and a Homes.com base past 35,000 subscribers. The model assumes a revenue CAGR near 13% and a net income margin expanding toward roughly 18%, with EPS compounding around 20%.
The margin driver is the whole rationale for the Rossmann hire: AI-led cost savings turning a still-growing top line into real operating leverage. The main risk is the mirror image: if Homes.com’s cash burn runs past management’s committed timelines, the margin story slips, and the stock can stay stuck here regardless of how strong the commercial base looks. Upside: residential turns profitable on schedule and the market re-rates a double-digit compounder. Downside: bookings stay soft, the inflection slips, and a cheap stock stays cheap.
Conclusion
Everything narrows to July 28. Watch two lines. First, residential adjusted EBITDA: guided from negative $29 million to breakeven-or-better. A print inside or above that range confirms the inflection the bull case depends on, landing three days before a cost-focused CFO takes over. A miss, or a walk-back of the range, hands Baird’s caution a second act. Second, net new bookings against RBC’s roughly $82 million estimate: a fourth straight sequential decline keeps the stalling-growth narrative alive no matter what EBITDA does.
Fundamentals and sentiment rarely point this far in opposite directions this close to a catalyst that settles the argument. In seven days, the market stops guessing.
