Does the August share price for Trex Company, Inc. (NYSE:TREX) reflect what it's really worth? Today, we will estimate the stock's intrinsic value by taking the expected future cash flows and discounting them to their present value. The Discounted Cash Flow (DCF) model is the tool we will apply to do this. Before you think you won't be able to understand it, just read on! It's actually much less complex than you'd imagine.

We would caution that there are many ways of valuing a company and, like the DCF, each technique has advantages and disadvantages in certain scenarios. Anyone interested in learning a bit more about intrinsic value should have a read of 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 start off with, we need to estimate 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.

A DCF is all about the idea that a dollar in the future is less valuable than a dollar today, so we discount the value of these future cash flows to their estimated value in today's dollars:

10-year free cash flow (FCF) estimate

	2024	2025	2026	2027	2028	2029	2030	2031	2032	2033
Levered FCF ($, Millions)	US$119.6m	US$229.0m	US$323.1m	US$418.2m	US$507.0m	US$585.7m	US$653.0m	US$709.8m	US$757.6m	US$798.2m
Growth Rate Estimate Source	Analyst x8	Analyst x1	Est @ 41.11%	Est @ 29.42%	Est @ 21.24%	Est @ 15.51%	Est @ 11.50%	Est @ 8.70%	Est @ 6.73%	Est @ 5.36%
Present Value ($, Millions) Discounted @ 7.7%	US$111	US$198	US$259	US$311	US$350	US$376	US$389	US$393	US$389	US$381

("Est" = FCF growth rate estimated by Simply Wall St)
Present Value of 10-year Cash Flow (PVCF) = US$3.2b

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 2.2%. We discount the terminal cash flows to today's value at a cost of equity of 7.7%.

Terminal Value (TV)= FCF₂₀₃₃ × (1 + g) ÷ (r – g) = US$798m× (1 + 2.2%) ÷ (7.7%– 2.2%) = US$15b

Present Value of Terminal Value (PVTV)= TV / (1 + r)¹⁰= US$15b÷ ( 1 + 7.7%)¹⁰= US$7.0b

The total value is the sum of cash flows for the next ten years plus the discounted terminal value, which results in the Total Equity Value, which in this case is US$10b. The last step is to then divide the equity value by the number of shares outstanding. Compared to the current share price of US$67.4, the company appears a touch undervalued at a 28% discount to where the stock price trades currently. Remember though, that this is just an approximate valuation, and like any complex formula - garbage in, garbage out.

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. Part of investing is coming up with your own evaluation of a company's future performance, so try the calculation yourself and check your own assumptions. 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 Trex Company 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 7.7%, which is based on a levered beta of 1.105. 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.
