Today we'll do a simple run through of a valuation method used to estimate the attractiveness of Quanex Building Products Corporation (NYSE:NX) as an investment opportunity by taking the foreast future cash flows of the company and discounting them back to today's value. This is done using the Discounted Cash Flow (DCF) model. Don't get put off by the jargon, the math behind it is actually quite straightforward.
Companies can be valued in a lot of ways, so we would point out that a DCF is not perfect for every situation. Anyone interested in learning a bit more about intrinsic value should have a read of the Simply Wall St analysis model.

Crunching the numbers
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. In the first stage we need to estimate the cash flows to the business over the next ten years. 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, 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
2019 | 2020 | 2021 | 2022 | 2023 | 2024 | 2025 | 2026 | 2027 | 2028 | |
Levered FCF ($, Millions) | $53.36 | $61.22 | $63.95 | $66.47 | $68.85 | $71.14 | $73.38 | $75.59 | $77.81 | $80.05 |
Growth Rate Estimate Source | Analyst x2 | Analyst x2 | Est @ 4.46% | Est @ 3.94% | Est @ 3.58% | Est @ 3.32% | Est @ 3.15% | Est @ 3.02% | Est @ 2.93% | Est @ 2.87% |
Present Value ($, Millions) Discounted @ 10.51% | $48.29 | $50.12 | $47.38 | $44.56 | $41.76 | $39.05 | $36.44 | $33.97 | $31.64 | $29.45 |
Present Value of 10-year Cash Flow (PVCF)= $402.67m
"Est" = FCF growth rate estimated by Simply Wall St
After calculating the present value of future cash flows in the intial 10-year period, we need to calculate the Terminal Value, which accounts for all future cash flows beyond the first stage. The Gordon Growth formula is used to calculate Terminal Value at a future annual growth rate equal to the 10-year government bond rate of 2.7%. We discount the terminal cash flows to today's value at a cost of equity of 10.5%.
Terminal Value (TV) = FCF2029 × (1 + g) ÷ (r – g) = US$80m × (1 + 2.7%) ÷ (10.5% – 2.7%) = US$1.1b
Present Value of Terminal Value (PVTV) = TV / (1 + r)10 = $US$1.1b ÷ ( 1 + 10.5%)10 = $388.72m
The total value, or equity value, is then the sum of the present value of the future cash flows, which in this case is $791.39m. In the final step we divide the equity value by the number of shares outstanding. This results in an intrinsic value estimate of $24.09. Relative to the current share price of $17.54, the company appears a touch undervalued at a 27% discount to where the stock price trades currently. 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
Now the most important inputs to a discounted cash flow are the discount rate, and of course, the actual cash flows. If you don't agree with these result, have a go at the calculation yourself and play with the 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 Quanex Building Products 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 10.5%, which is based on a levered beta of 1.306. 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:
Whilst important, DCF calculation shouldn’t be the only metric you look at when researching a company. The DCF model is not a perfect stock valuation tool. Rather it should be seen as a guide to "what assumptions need to be true for this stock to be under/overvalued?" If a company grows at a different rate, or if its cost of equity or risk free rate changes sharply, the output can look very different. What is the reason for the share price to differ from the intrinsic value? For Quanex Building Products, I've compiled three fundamental factors you should further research:
