How far off is Western Digital Corporation (NASDAQ:WDC) from its intrinsic value? Using the most recent financial data, we'll take a look at whether the stock is fairly priced by taking the expected future cash flows and discounting them to their present value. We will use the Discounted Cash Flow (DCF) model on this occasion. Models like these may appear beyond the comprehension of a lay person, but they're fairly easy to follow.
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.
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.
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
2025 | 2026 | 2027 | 2028 | 2029 | 2030 | 2031 | 2032 | 2033 | 2034 | |
Levered FCF ($, Millions) | US$2.19b | US$2.61b | US$1.97b | US$2.00b | US$2.12b | US$2.04b | US$2.00b | US$1.99b | US$2.00b | US$2.02b |
Growth Rate Estimate Source | Analyst x6 | Analyst x5 | Analyst x3 | Analyst x1 | Analyst x1 | Est @ -3.84% | Est @ -1.90% | Est @ -0.54% | Est @ 0.41% | Est @ 1.07% |
Present Value ($, Millions) Discounted @ 8.2% | US$2.0k | US$2.2k | US$1.6k | US$1.5k | US$1.4k | US$1.3k | US$1.1k | US$1.1k | US$979 | US$915 |
("Est" = FCF growth rate estimated by Simply Wall St)
Present Value of 10-year Cash Flow (PVCF) = US$14b
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. 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 2.6%. We discount the terminal cash flows to today's value at a cost of equity of 8.2%.
Terminal Value (TV)= FCF2034 × (1 + g) ÷ (r – g) = US$2.0b× (1 + 2.6%) ÷ (8.2%– 2.6%) = US$37b
Present Value of Terminal Value (PVTV)= TV / (1 + r)10= US$37b÷ ( 1 + 8.2%)10= US$17b
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$31b. The last step is to then divide the equity value by the number of shares outstanding. Compared to the current share price of US$61.6, the company appears quite good value at a 31% 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.
The Assumptions
The calculation above is very dependent on two assumptions. The first is the discount rate and the other is the 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 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 8.2%, which is based on a levered beta of 1.364. 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.

Moving On:
Whilst important, the DCF calculation ideally won't be the sole piece of analysis you scrutinize for a company. It's not possible to obtain a foolproof valuation with a DCF model. 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 instance, if the terminal value growth rate is adjusted slightly, it can dramatically alter the overall result. Why is the intrinsic value higher than the current share price? For Western Digital, there are three relevant items you should assess:
