Approach 1: Comfort Systems USA Discounted Cash Flow (DCF) Analysis

A Discounted Cash Flow model estimates what a company is worth by projecting its future cash flows and discounting them back to today to reflect the time value and risk of that money.

For Comfort Systems USA, the latest twelve month Free Cash Flow is about $798.7 Million. Analysts and extrapolated estimates used in this 2 Stage Free Cash Flow to Equity model see cash flows rising steadily, reaching roughly $4.0 Billion by 2035. These projections reflect a period of faster growth in the near term, followed by moderating but still healthy expansion as the business matures.

When all those future cash flows are discounted back, the model arrives at an intrinsic value of about $1,476.44 per share. That implies the shares are trading at a 34.4% discount to this estimate, suggesting the market is not fully pricing in the projected cash generation or its durability.

Result: UNDERVALUED

Our Discounted Cash Flow (DCF) analysis suggests Comfort Systems USA is undervalued by 34.4%. Track this in your watchlist or portfolio, or discover 909 more undervalued stocks based on cash flows.

Approach 2: Comfort Systems USA Price vs Earnings

For profitable companies like Comfort Systems USA, the price to earnings ratio is a useful yardstick because it connects what investors pay today to the earnings the business is already generating. A higher or lower PE should reflect how quickly earnings are expected to grow and how risky or cyclical those earnings are, so a fair range is always tied to both growth prospects and uncertainty.

Comfort Systems USA currently trades on about 40.69x earnings, which is above the broader Construction industry average of roughly 32.44x but below the peer group average of around 61.15x. Simply Wall St also calculates a Fair Ratio of 43.65x, a proprietary estimate of what the multiple should be given Comfort Systems USA's growth profile, margins, industry, size and risk factors. This tends to be more informative than a simple peer or industry comparison, because it adjusts for the specific earnings outlook and quality of the company rather than assuming all contractors deserve the same valuation.

With the actual PE of 40.69x sitting below the 43.65x Fair Ratio, the shares appear modestly undervalued on this metric, even after their strong run.

Result: UNDERVALUED
