In this article we are going to estimate the intrinsic value of Comfort Systems USA, Inc. (NYSE:FIX) by estimating the company's future cash flows and discounting them to their present value. We will use the Discounted Cash Flow (DCF) model on this occasion. Believe it or not, it's not too difficult to follow, as you'll see from our example!
Companies can be valued in a lot of ways, so we would point out that a DCF is not perfect for every situation. If you want to learn more about discounted cash flow, the rationale behind this calculation can be read in detail in the Simply Wall St analysis model.
What's The Estimated Valuation?
We use what is known as a 2-stage model, which simply means we have two different periods of growth rates for the company's cash flows. Generally the first stage is higher growth, and the second stage is a lower growth phase. To begin with, we have to get estimates of the next ten years of cash flows. Where possible we use analyst estimates, but when these aren't available we extrapolate the previous free cash flow (FCF) from the last estimate or reported value. We assume companies with shrinking free cash flow will slow their rate of shrinkage, and that companies with growing free cash flow will see their growth rate slow, over this period. We do this to reflect that growth tends to slow more in the early years than it does in later years.
Generally we assume that a dollar today is more valuable than a dollar in the future, and so the sum of these future cash flows is then discounted to today's value:
10-year free cash flow (FCF) estimate
2025 | 2026 | 2027 | 2028 | 2029 | 2030 | 2031 | 2032 | 2033 | 2034 | |
Levered FCF ($, Millions) | US$566.1m | US$546.8m | US$537.8m | US$535.6m | US$538.2m | US$544.0m | US$552.2m | US$562.1m | US$573.4m | US$585.8m |
Growth Rate Estimate Source | Analyst x3 | Est @ -3.42% | Est @ -1.64% | Est @ -0.40% | Est @ 0.47% | Est @ 1.08% | Est @ 1.51% | Est @ 1.80% | Est @ 2.01% | Est @ 2.16% |
Present Value ($, Millions) Discounted @ 6.7% | US$530 | US$480 | US$443 | US$413 | US$389 | US$368 | US$350 | US$334 | US$320 | US$306 |
("Est" = FCF growth rate estimated by Simply Wall St)
Present Value of 10-year Cash Flow (PVCF) = US$3.9b
The second stage is also known as Terminal Value, this is the business's cash flow after the first stage. The Gordon Growth formula is used to calculate Terminal Value at a future annual growth rate equal to the 5-year average of the 10-year government bond yield of 2.5%. We discount the terminal cash flows to today's value at a cost of equity of 6.7%.
Terminal Value (TV)= FCF2034 × (1 + g) ÷ (r – g) = US$586m× (1 + 2.5%) ÷ (6.7%– 2.5%) = US$14b
Present Value of Terminal Value (PVTV)= TV / (1 + r)10= US$14b÷ ( 1 + 6.7%)10= US$7.4b
The total value, or equity value, is then the sum of the present value of the future cash flows, which in this case is US$11b. The last step is to then divide the equity value by the number of shares outstanding. Relative to the current share price of US$337, the company appears around fair value at the time of writing. The assumptions in any calculation have a big impact on the valuation, so it is better to view this as a rough estimate, not precise down to the last cent.

Important Assumptions
We would point out that the most important inputs to a discounted cash flow are the discount rate and of course the actual cash flows. You don't have to agree with these inputs, I recommend redoing the calculations yourself and playing with them. The DCF also does not consider the possible cyclicality of an industry, or a company's future capital requirements, so it does not give a full picture of a company's potential performance. Given that we are looking at Comfort Systems USA as potential shareholders, the cost of equity is used as the discount rate, rather than the cost of capital (or weighted average cost of capital, WACC) which accounts for debt. In this calculation we've used 6.7%, which is based on a levered beta of 1.023. Beta is a measure of a stock's volatility, compared to the market as a whole. We get our beta from the industry average beta of globally comparable companies, with an imposed limit between 0.8 and 2.0, which is a reasonable range for a stable business.

Next Steps:
Although the valuation of a company is important, it is only one of many factors that you need to assess for a company. DCF models are not the be-all and end-all of investment valuation. Preferably you'd apply different cases and assumptions and see how they would impact the company's valuation. For instance, if the terminal value growth rate is adjusted slightly, it can dramatically alter the overall result. For Comfort Systems USA, we've compiled three additional items you should consider:
- Risks: We feel that you should assess the 1 warning sign for Comfort Systems USA we've flagged before making an investment in the company.
