Approach 1: CoStar Group Discounted Cash Flow (DCF) Analysis

A Discounted Cash Flow model takes estimates of a company’s future cash flows and discounts them back to today using a required rate of return, giving an estimate of what the whole business could be worth in today’s dollars.

For CoStar Group, the model used is a 2 Stage Free Cash Flow to Equity approach. The latest twelve month free cash flow is about $59.5m. Analyst estimates and Simply Wall St extrapolations project free cash flow rising to $944.7m by 2028, with further projections extending out to 2035, all in $ terms. Each of these projected cash flows is discounted back to today to reflect risk and the time value of money.

Bringing those discounted cash flows together, the DCF model suggests an intrinsic value of about $64.30 per share, compared with the recent share price around $33.89. On this basis, the stock screens as about 47.3% below the model’s estimate of fair value. This indicates a wide valuation gap.

Result: UNDERVALUED

Approach 2: CoStar Group Price vs Sales

For profitable companies, the price to sales ratio, or P/S, can be a useful cross check on value because it compares what you pay for each dollar of revenue to what the market pays for similar businesses.

What counts as a “normal” P/S depends on how fast revenue is expected to grow and how risky those cash flows appear. Higher growth or lower perceived risk can justify a higher P/S, while slower growth or higher risk usually points to a lower multiple.

CoStar Group currently trades on a P/S of 4.06x. That sits above the Real Estate industry average of 2.55x and above the peer average of 1.40x. Simply Wall St’s Fair Ratio framework estimates what a stock’s preferred multiple might be based on factors like earnings growth, margins, industry, market cap and specific risks. Because it blends these company specific inputs, it can be more informative than a simple comparison with peers or the broad industry.

For CoStar Group, the Fair Ratio is 4.01x versus the current 4.06x, which is a very small difference, so the stock screens as about fairly valued on this metric.
