The case for CSGP
- Revenue up 20.2% on the year.
- Holds more cash ($1.6B) than long-term debt ($993M).
- Earnings per share up 747.6%.
- Has compounded revenue at 14.4% a year over five years.
- Gross margin of 78% absorbs cost shocks.
- Moves less than the market (beta 0.78).
The case against
- Expensive for its growth: 67.4× earnings, where 5% a year of growth would justify about 15×.
- Down 53.7% over the past year.
- Return on equity of only 2%.
- Near the bottom of its 52-week range, 57% below the high. Falling prices usually have a reason; find it first.

What the score is made of
Each factor is half a curve over reported figures and half a rank among the other Real Estate companies (momentum is judged against fixed thresholds only), and the five are blended by weight. The score is where that blend places it in the S&P 500. It describes the last filing and the current price. It is not a forecast.

| Profitabilityhow much of the revenue becomes profit, and how much of that is cash | 34 |
| Momentumhow the price has behaved lately | 21 |
| Stabilityhow violently it moves, what it owes and what it pays you | 70 |
- Each factor except momentum is half fixed thresholds, half rank among the 30 Real Estate companies.
The financials
Revenue growth
Is the business growing? Yes
| Last 12 months | +20.2% |
|---|---|
| Over 5 years | +14.4% a year |
| FY2025 revenue | $3.2B (+19%) |
Free cash flow
Is it generating real cash? A little
| FY2025 free cash flow | $123M |
|---|---|
| Of revenue | 4% |
| Of profit | 1757% |
Profit margins
Is profitability improving? Holding steady
| Gross margin | 78% |
|---|---|
| Operating margin | 6% |
| Net margin, FY24 → FY25 → now | 5.1% → 0.2% → 4.9% |
Debt vs. cash
Is the balance sheet healthy? Yes, more cash than debt
| Cash | $1.6B |
|---|---|
| Long-term debt | $993M |
| Net cash | $640M |
| Years to repay | 2.3 yrs |
Valuation
Is the stock price reasonable? No, expensive
| P/E | 67.4× |
|---|---|
| Fair P/E for its growth | 15× |
| Price / operating cash flow | 28.0× |
| Forward P/E | 17.7× |
| EV / EBITDA | 33.7× |
At 67.4× earnings it trades well above the 15× that 5% a year of growth would justify. At 28.0× operating cash flow it trades well above that same mark; for a REIT that counts for more than earnings, since depreciation makes its P/E look worse than the business is.
