Today we will run through one way of estimating the intrinsic value of Northrop Grumman Corporation (NYSE:NOC) 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. Believe it or not, it's not too difficult to follow, as you'll see from our example!
We generally believe that a company's value is the present value of all of the cash it will generate in the future. However, a DCF is just one valuation metric among many, and it is not without flaws. If you still have some burning questions about this type of valuation, take a look at the Simply Wall St analysis model.
Step by step through the calculation
We are going to use a two-stage DCF model, which, as the name states, takes into account two stages of growth. The first stage is generally a higher growth period which levels off heading towards the terminal value, captured in the second 'steady growth' period. 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) forecast
|Levered FCF ($, Millions)||US$3.50b||US$3.68b||US$4.10b||US$4.25b||US$4.37b||US$4.48b||US$4.59b||US$4.69b||US$4.79b||US$4.90b|
|Growth Rate Estimate Source||Analyst x8||Analyst x8||Analyst x4||Analyst x3||Est @ 2.83%||Est @ 2.58%||Est @ 2.4%||Est @ 2.28%||Est @ 2.19%||Est @ 2.13%|
|Present Value ($, Millions) Discounted @ 7.0%||US$3.3k||US$3.2k||US$3.3k||US$3.2k||US$3.1k||US$3.0k||US$2.9k||US$2.7k||US$2.6k||US$2.5k|
("Est" = FCF growth rate estimated by Simply Wall St)
Present Value of 10-year Cash Flow (PVCF) = US$30b
After calculating the present value of future cash flows in the initial 10-year period, we need to calculate the Terminal Value, which accounts for all future cash flows beyond the first stage. 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 (2.0%) 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 7.0%.
Terminal Value (TV)= FCF2031 × (1 + g) ÷ (r – g) = US$4.9b× (1 + 2.0%) ÷ (7.0%– 2.0%) = US$99b
Present Value of Terminal Value (PVTV)= TV / (1 + r)10= US$99b÷ ( 1 + 7.0%)10= US$51b
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$80b. In the final step we divide the equity value by the number of shares outstanding. Compared to the current share price of US$363, the company appears a touch undervalued at a 28% discount to where the stock price trades currently. 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.
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 Northrop Grumman 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 7.0%, which is based on a levered beta of 1.063. 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.
Whilst important, the DCF calculation shouldn't be the only metric you look at when researching a company. It's not possible to obtain a foolproof valuation with a DCF model. Preferably you'd apply different cases and assumptions and see how they would impact the company's valuation. 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.
