Today we'll do a simple run through of a valuation method used to estimate the attractiveness of General Dynamics Corporation (NYSE:GD) as an investment opportunity by projecting its future cash flows and then discounting them to today's value. This will be done using the Discounted Cash Flow (DCF) model. Don't get put off by the jargon, the math behind it is actually quite straightforward.
Remember though, that there are many ways to estimate a company's value, and a DCF is just one method. For those who are keen learners of equity analysis, the Simply Wall St analysis model here may be something of interest to you.
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. 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, and so the sum of these future cash flows is then discounted to today's value:
10-year free cash flow (FCF) forecast
|Levered FCF ($, Millions)||US$3.11b||US$3.68b||US$4.26b||US$3.86b||US$3.65b||US$3.53b||US$3.47b||US$3.46b||US$3.47b||US$3.50b|
|Growth Rate Estimate Source||Analyst x9||Analyst x8||Analyst x3||Analyst x1||Est @ -5.58%||Est @ -3.24%||Est @ -1.6%||Est @ -0.46%||Est @ 0.35%||Est @ 0.91%|
|Present Value ($, Millions) Discounted @ 8.5%||US$2.9k||US$3.1k||US$3.3k||US$2.8k||US$2.4k||US$2.2k||US$2.0k||US$1.8k||US$1.7k||US$1.5k|
("Est" = FCF growth rate estimated by Simply Wall St)
Present Value of 10-year Cash Flow (PVCF) = US$24b
We now need to calculate the Terminal Value, which accounts for all the future cash flows after this ten year period. 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 8.5%.
Terminal Value (TV)= FCF2030 × (1 + g) ÷ (r – g) = US$3.5b× (1 + 2.2%) ÷ (8.5%– 2.2%) = US$57b
Present Value of Terminal Value (PVTV)= TV / (1 + r)10= US$57b÷ ( 1 + 8.5%)10= US$25b
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$49b. To get the intrinsic value per share, we divide this by the total number of shares outstanding. Relative to the current share price of US$156, the company appears about fair value at a 8.2% 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.
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 General Dynamics 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 8.5%, which is based on a levered beta of 1.049. 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.
Although the valuation of a company is important, it ideally won't be the sole piece of analysis you scrutinize for a company. DCF models are not the be-all and end-all of investment valuation. 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 General Dynamics, there are three fundamental aspects you should consider:
