Today we will run through one way of estimating the intrinsic value of BWX Technologies, Inc. (NYSE:BWXT) by taking the expected future cash flows and discounting them to today's value. This is done using the Discounted Cash Flow (DCF) model. It may sound complicated, but actually it is quite simple!
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. 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 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. 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.
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)||$60.90||$174.44||$262.73||$318.00||$312.00||$310.39||$311.82||$315.37||$320.47||$326.72|

|Present Value ($, Millions) Discounted @ 8.71%||$56.02||$147.61||$204.52||$227.71||$205.51||$188.08||$173.80||$161.70||$151.15||$141.76|
Present Value of 10-year Cash Flow (PVCF)= $1.66b
"Est" = FCF growth rate estimated by Simply Wall St
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 10-year government bond rate of 2.7%. We discount the terminal cash flows to today's value at a cost of equity of 8.7%.
Terminal Value (TV) = FCF2029 × (1 + g) ÷ (r – g) = US$327m × (1 + 2.7%) ÷ (8.7% – 2.7%) = US$5.6b
Present Value of Terminal Value (PVTV) = TV / (1 + r)10 = $US$5.6b ÷ ( 1 + 8.7%)10 = $2.44b
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 $4.09b. 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 $43.02. Relative to the current share price of $50.4, 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.
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 BWX Technologies 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 8.7%, which is based on a levered beta of 1.003. 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.
Valuation is only one side of the coin in terms of building your investment thesis, and it 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.
