Estimating The Fair Value Of TransDigm Group Incorporated (NYSE:TDG)

Key Insights

• Using the 2 Stage Free Cash Flow to Equity, TransDigm Group fair value estimate is US$690
• With US$810 share price, TransDigm Group appears to be trading close to its estimated fair value
• The US$836 analyst price target for TDG is 21% more than our estimate of fair value

In this article we are going to estimate the intrinsic value of TransDigm Group Incorporated (NYSE:TDG) by taking the expected future cash flows and discounting them to today's value. We will use the Discounted Cash Flow (DCF) model on this occasion. It may sound complicated, but actually it is quite simple!

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 still have some burning questions about this type of valuation, take a look at 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.

A DCF is all about the idea that a dollar in the future is less valuable than a dollar today, so we need to discount the sum of these future cash flows to arrive at a present value estimate:

10-year free cash flow (FCF) forecast

	2023	2024	2025	2026	2027	2028	2029	2030	2031	2032
Levered FCF ($, Millions)	US$1.32b	US$1.64b	US$1.89b	US$2.10b	US$2.25b	US$2.38b	US$2.49b	US$2.59b	US$2.67b	US$2.75b
Growth Rate Estimate Source	Analyst x6	Analyst x6	Analyst x5	Analyst x2	Est @ 7.25%	Est @ 5.71%	Est @ 4.63%	Est @ 3.87%	Est @ 3.34%	Est @ 2.97%
Present Value ($, Millions) Discounted @ 7.8%	US$1.2k	US$1.4k	US$1.5k	US$1.6k	US$1.5k	US$1.5k	US$1.5k	US$1.4k	US$1.4k	US$1.3k

("Est" = FCF growth rate estimated by Simply Wall St)
Present Value of 10-year Cash Flow (PVCF) = US$14b

We now need to calculate the Terminal Value, which accounts for all the future cash flows after this ten year period. For a number of reasons a very conservative growth rate is used that cannot exceed that of a country's GDP growth. In this case we have used the 5-year average of the 10-year government bond yield (2.1%) to estimate future growth. In the same way as with the 10-year 'growth' period, we discount future cash flows to today's value, using a cost of equity of 7.8%.

Terminal Value (TV)= FCF₂₀₃₂ × (1 + g) ÷ (r – g) = US$2.8b× (1 + 2.1%) ÷ (7.8%– 2.1%) = US$49b

Present Value of Terminal Value (PVTV)= TV / (1 + r)¹⁰= US$49b÷ ( 1 + 7.8%)¹⁰= US$23b

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$38b. The last step is to then divide the equity value by the number of shares outstanding. Compared to the current share price of US$810, 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 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 7.8%, which is based on a levered beta of 0.957. 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.

SWOT Analysis for TransDigm Group

Looking Ahead:

Although the valuation of a company is important, it shouldn't be the only metric you look at when researching a company. The DCF model is not a perfect stock valuation tool. Instead the best use for a DCF model is to test certain assumptions and theories to see if they would lead to the company being undervalued or overvalued. For example, changes in the company's cost of equity or the risk free rate can significantly impact the valuation. For TransDigm Group, there are three important items you should further research:

1. Risks: Consider for instance, the ever-present spectre of investment risk. We've identified 3 warning signs with TransDigm Group (at least 2 which are a bit concerning) , and understanding these should be part of your investment process.
