In this article we are going to estimate the intrinsic value of OSI Systems, Inc. (NASDAQ:OSIS) by taking the forecast future cash flows of the company and discounting them back to today's value. One way to achieve this is by employing the Discounted Cash Flow (DCF) model. Models like these may appear beyond the comprehension of a lay person, but they're fairly easy to follow.
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 still have some burning questions about this type of valuation, take a look at the Simply Wall St analysis model.
Is OSI Systems fairly valued?
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. 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, so we discount the value of these future cash flows to their estimated value in today's dollars:
10-year free cash flow (FCF) estimate
|Levered FCF ($, Millions)||US$71.2m||US$123.0m||US$129.5m||US$134.5m||US$139.0m||US$143.0m||US$146.7m||US$150.2m||US$153.6m||US$156.9m|
|Growth Rate Estimate Source||Analyst x3||Analyst x3||Analyst x2||Est @ 3.89%||Est @ 3.3%||Est @ 2.89%||Est @ 2.6%||Est @ 2.39%||Est @ 2.25%||Est @ 2.15%|
|Present Value ($, Millions) Discounted @ 7.2%||US$66.4||US$107||US$105||US$102||US$98.2||US$94.2||US$90.2||US$86.2||US$82.2||US$78.3|
("Est" = FCF growth rate estimated by Simply Wall St)
Present Value of 10-year Cash Flow (PVCF) = US$909m
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 5-year average of the 10-year government bond yield of 1.9%. We discount the terminal cash flows to today's value at a cost of equity of 7.2%.
Terminal Value (TV)= FCF2031 × (1 + g) ÷ (r – g) = US$157m× (1 + 1.9%) ÷ (7.2%– 1.9%) = US$3.0b
Present Value of Terminal Value (PVTV)= TV / (1 + r)10= US$3.0b÷ ( 1 + 7.2%)10= US$1.5b
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$2.4b. The last step is to then divide the equity value by the number of shares outstanding. Compared to the current share price of US$83.9, the company appears quite undervalued at a 41% 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.
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. Part of investing is coming up with your own evaluation of a company's future performance, so try the calculation yourself and check your own 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 OSI Systems 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 7.2%, which is based on a levered beta of 1.244. 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. It's not possible to obtain a foolproof valuation with a DCF model. Rather it should be seen as a guide to "what assumptions need to be true for this stock to be under/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?
