Estimating The Fair Value Of Interlink Electronics, Inc. (NASDAQ:LINK)

Today we'll do a simple run through of a valuation method used to estimate the attractiveness of Interlink Electronics, Inc. (NASDAQ:LINK) as an investment opportunity by taking the forecast future cash flows of the company and discounting them back to today's 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 would caution that there are many ways of valuing a company and, like the DCF, each technique has advantages and disadvantages in certain scenarios. 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.

The calculation

We use what is known as a 2-stage model, which simply means we have two different periods of growth rates for the company's cash flows. Generally the first stage is higher growth, and the second stage is a lower growth phase. To begin with, we have to get estimates of the next ten years of cash flows. Seeing as no analyst estimates of free cash flow are available to us, we have extrapolate the previous free cash flow (FCF) from the company's last 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

	2022	2023	2024	2025	2026	2027	2028	2029	2030	2031
Levered FCF ($, Millions)	US$763.7k	US$1.21m	US$1.71m	US$2.21m	US$2.68m	US$3.09m	US$3.44m	US$3.74m	US$3.98m	US$4.19m
Growth Rate Estimate Source	Est @ 82.16%	Est @ 58.1%	Est @ 41.26%	Est @ 29.47%	Est @ 21.22%	Est @ 15.44%	Est @ 11.4%	Est @ 8.56%	Est @ 6.58%	Est @ 5.2%
Present Value ($, Millions) Discounted @ 6.9%	US$0.7	US$1.1	US$1.4	US$1.7	US$1.9	US$2.1	US$2.2	US$2.2	US$2.2	US$2.1

("Est" = FCF growth rate estimated by Simply Wall St)
Present Value of 10-year Cash Flow (PVCF) = US$17m

The second stage is also known as Terminal Value, this is the business's cash flow after 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 6.9%.

Terminal Value (TV)= FCF₂₀₃₁ × (1 + g) ÷ (r – g) = US$4.2m× (1 + 2.0%) ÷ (6.9%– 2.0%) = US$86m

Present Value of Terminal Value (PVTV)= TV / (1 + r)¹⁰= US$86m÷ ( 1 + 6.9%)¹⁰= US$44m

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$61m. In the final step we divide the equity value by the number of shares outstanding. Relative to the current share price of US$9.4, the company appears around fair value at the time of writing. Remember though, that this is just an approximate valuation, and like any complex formula - garbage in, garbage out.

Important 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 Interlink Electronics 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 6.9%, which is based on a levered beta of 1.132. 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.

Looking Ahead:

Although the valuation of a company is important, it ideally won't be the sole piece of analysis you scrutinize for a company. The DCF model is not a perfect stock valuation tool. 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. 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.
