Today we'll do a simple run through of a valuation method used to estimate the attractiveness of TransDigm Group Incorporated ( NYSE:TDG ) as an investment opportunity by taking the expected future cash flows and discounting them to today's value. I will use the Discounted Cash Flow (DCF) model. It may sound complicated, but actually it is quite simple!
Remember though, that there are many ways to estimate a company's value, and a DCF is just one method. Anyone interested in learning a bit more about intrinsic value should have a read of the Simply Wall St analysis model .

The method
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
2020 | 2021 | 2022 | 2023 | 2024 | 2025 | 2026 | 2027 | 2028 | 2029 | |
Levered FCF ($, Millions) | $1.3b | $1.5b | $1.7b | $1.8b | $1.9b | $2.0b | $2.1b | $2.2b | $2.3b | $2.4b |
Growth Rate Estimate Source | Analyst x10 | Analyst x6 | Analyst x2 | Analyst x1 | Est @ 6.48% | Est @ 5.35% | Est @ 4.57% | Est @ 4.02% | Est @ 3.63% | Est @ 3.36% |
Present Value ($, Millions) Discounted @ 10.03% | $1.2k | $1.2k | $1.3k | $1.2k | $1.2k | $1.1k | $1.1k | $1.0k | $971.5 | $912.6 |
("Est" = FCF growth rate estimated by Simply Wall St)
Present Value of 10-year Cash Flow (PVCF)
= $11.3b
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%.
Terminal Value (TV) = FCF _{ 2029 } Ã— (1 + g) Ã· (r â€“ g) = US$2.4b Ã— (1 + 2.7%) Ã· (10% â€“ 2.7%) = US$33b
Present Value of Terminal Value (PVTV) = TV / (1 + r) ^{ 10 } = $US$33b Ã· ( 1 + 10%) ^{ 10 } = $12.84b
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 $24.11b. To get the intrinsic value per share, we divide this by the total number of shares outstanding. This results in an intrinsic value estimate of $453.32 . Relative to the current share price of $498.06, the company appears around fair value at the time of writing. Valuations are imprecise instruments though, rather like a telescope - move a few degrees and end up in a different galaxy. Do keep this in mind.
Important assumptions
Now 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 TransDigm Group 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%, which is based on a levered beta of 1.225. 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 shouldnâ€™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.
