# Calculating The Intrinsic Value Of MKS Instruments, Inc. (NASDAQ:MKSI)

Does the March share price for MKS Instruments, Inc. (NASDAQ:MKSI) reflect what it’s really worth? Today, we will estimate the stock’s intrinsic value by projecting its future cash flows and then discounting them to today’s value. This is done using 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.

### Is MKS Instruments fairly valued?

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.

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) estimate

(“Est” = FCF growth rate estimated by Simply Wall St)
Present Value of 10-year Cash Flow (PVCF) = US\$2.8b

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 1.7%. 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\$369m× (1 + 1.7%) ÷ 8.7%– 1.7%) = US\$5.4b

Present Value of Terminal Value (PVTV)= TV / (1 + r)10= US\$5.4b÷ ( 1 + 8.7%)10= US\$2.3b

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\$5.1b. To get the intrinsic value per share, we divide this by the total number of shares outstanding. Compared to the current share price of US\$83.8, the company appears about fair value at a 11% 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.

### The assumptions

Now 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 MKS Instruments 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 1.287. 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:

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. For MKS Instruments, There are three fundamental factors you should look at:

1. Risks: Take risks, for example – MKS Instruments has 4 warning signs we think you should be aware of.
2. Future Earnings: How does MKSI’s growth rate compare to its peers and the wider market? Dig deeper into the analyst consensus number for the upcoming years by interacting with our free analyst growth expectation chart.
