Is There An Opportunity With Ciena Corporation's (NYSE:CIEN) 34% Undervaluation?

Key Insights

• Ciena's estimated fair value is US$98.31 based on 2 Stage Free Cash Flow to Equity
• Current share price of US$65.33 suggests Ciena is potentially 34% undervalued
• Analyst price target for CIEN is US$64.33 which is 35% below our fair value estimate

Today we'll do a simple run through of a valuation method used to estimate the attractiveness of Ciena Corporation (NYSE:CIEN) as an investment opportunity by projecting its future cash flows and then discounting them to today's value. This will be done using the Discounted Cash Flow (DCF) model. Don't get put off by the jargon, the math behind it is actually quite straightforward.

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. 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 start off with, we need to estimate 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$454.8m	US$535.0m	US$576.0m	US$607.7m	US$635.7m	US$661.0m	US$684.3m	US$706.3m	US$727.6m	US$748.3m
Growth Rate Estimate Source	Analyst x3	Analyst x2	Analyst x1	Est @ 5.51%	Est @ 4.60%	Est @ 3.97%	Est @ 3.53%	Est @ 3.22%	Est @ 3.01%	Est @ 2.85%
Present Value ($, Millions) Discounted @ 6.6%	US$427	US$471	US$475	US$470	US$461	US$450	US$437	US$423	US$408	US$394

("Est" = FCF growth rate estimated by Simply Wall St)
Present Value of 10-year Cash Flow (PVCF) = US$4.4b

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 (2.5%) 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 6.6%.

Terminal Value (TV)= FCF₂₀₃₄ × (1 + g) ÷ (r – g) = US$748m× (1 + 2.5%) ÷ (6.6%– 2.5%) = US$19b

Present Value of Terminal Value (PVTV)= TV / (1 + r)¹⁰= US$19b÷ ( 1 + 6.6%)¹⁰= US$9.8b

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$14b. 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$65.3, the company appears quite good value at a 34% discount to where the stock price trades currently. Remember though, that this is just an approximate valuation, and like any complex formula - garbage in, garbage out.

Important Assumptions

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. 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 Ciena 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 6.6%, which is based on a levered beta of 1.002. 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:

Although the valuation of a company is important, it shouldn't be the only metric you look at when researching a company. The DCF model is not a perfect stock valuation tool. Preferably you'd apply different cases and assumptions and see how they would impact the company's valuation. 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?
