In this article we are going to estimate the intrinsic value of Western Digital Corporation (NASDAQ:WDC) by taking the expected future cash flows and discounting them to today's value. I will use the Discounted Cash Flow (DCF) model. Don't get put off by the jargon, the math behind it is actually quite straightforward.

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 want to learn more about discounted cash flow, the rationale behind this calculation can be read in detail in 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. 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) estimate

 2020 2021 2022 2023 2024 2025 2026 2027 2028 2029 Levered FCF (\$, Millions) \$1.6b \$2.0b \$2.4b \$2.7b \$3.0b \$3.2b \$3.4b \$3.6b \$3.8b \$3.9b Growth Rate Estimate Source Analyst x4 Analyst x1 Est @ 18.07% Est @ 13.47% Est @ 10.25% Est @ 7.99% Est @ 6.41% Est @ 5.31% Est @ 4.53% Est @ 3.99% Present Value (\$, Millions) Discounted @ 11.62% \$1.4k \$1.6k \$1.7k \$1.7k \$1.7k \$1.7k \$1.6k \$1.5k \$1.4k \$1.3k

("Est" = FCF growth rate estimated by Simply Wall St)
Present Value of 10-year Cash Flow (PVCF)= \$15.6b

The second stage is also known as Terminal Value, this is the business's cash flow after 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 11.6%.

Terminal Value (TV) = FCF2029 Ã— (1 + g) Ã· (r â€“ g) = US\$3.9b Ã— (1 + 2.7%) Ã· (11.6% â€“ 2.7%) = US\$45b

Present Value of Terminal Value (PVTV) = TV / (1 + r)10 = \$US\$45b Ã· ( 1 + 11.6%)10 = \$15.04b

The total value, or equity value, is then the sum of the present value of the future cash flows, which in this case is \$30.65b. In the final step we divide the equity value by the number of shares outstanding. This results in an intrinsic value estimate of \$104.6. Relative to the current share price of \$52.88, the company appears quite good value at a 49% discount to where the stock price trades currently. Remember though, that this is just an approximate valuation, and like any complex formula - garbage in, garbage out.

### Important assumptions

The calculation above is very dependent on two assumptions. The first is the discount rate and the other is the 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 Western Digital 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 11.6%, which is based on a levered beta of 1.491. 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:

Whilst important, DCF calculation 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. What is the reason for the share price to differ from the intrinsic value? For Western Digital, There are three further factors you should further examine:
