How far off is Calix, Inc. (NYSE:CALX) 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. One way to achieve this is by employing the Discounted Cash Flow (DCF) model. Before you think you won't be able to understand it, just read on! It's actually much less complex than you'd imagine.

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 Method

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 need to discount the sum of these future cash flows to arrive at a present value estimate:

10-year free cash flow (FCF) estimate

	2024	2025	2026	2027	2028	2029	2030	2031	2032	2033
Levered FCF ($, Millions)	US$105.0m	US$135.0m	US$157.6m	US$177.1m	US$193.6m	US$207.5m	US$219.2m	US$229.3m	US$238.2m	US$246.1m
Growth Rate Estimate Source	Analyst x1	Analyst x1	Est @ 16.75%	Est @ 12.37%	Est @ 9.31%	Est @ 7.16%	Est @ 5.66%	Est @ 4.60%	Est @ 3.87%	Est @ 3.35%
Present Value ($, Millions) Discounted @ 7.1%	US$98.1	US$118	US$128	US$135	US$138	US$138	US$136	US$133	US$129	US$124

("Est" = FCF growth rate estimated by Simply Wall St)
Present Value of 10-year Cash Flow (PVCF) = US$1.3b

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 (2.2%) 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 7.1%.

Terminal Value (TV)= FCF₂₀₃₃ × (1 + g) ÷ (r – g) = US$246m× (1 + 2.2%) ÷ (7.1%– 2.2%) = US$5.1b

Present Value of Terminal Value (PVTV)= TV / (1 + r)¹⁰= US$5.1b÷ ( 1 + 7.1%)¹⁰= US$2.6b

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$3.9b. In the final step we divide the equity value by the number of shares outstanding. Compared to the current share price of US$42.5, the company appears a touch undervalued at a 27% 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.

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 Calix 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 7.1%, which is based on a levered beta of 0.981. 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.

SWOT Analysis for Calix

Looking Ahead:

Whilst important, the DCF calculation 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?" For example, changes in the company's cost of equity or the risk free rate can significantly impact the valuation. Why is the intrinsic value higher than the current share price? For Calix, there are three further factors you should further examine:

1. Risks: Every company has them, and we've spotted 2 warning signs for Calix you should know about.
2. Management:Have insiders been ramping up their shares to take advantage of the market's sentiment for CALX's future outlook? Check out our management and board analysis with insights on CEO compensation and governance factors.
