Is Codexis, Inc. (NASDAQ:CDXS) Trading At A 28% Discount?

Today we'll do a simple run through of a valuation method used to estimate the attractiveness of Codexis, Inc. (NASDAQ:CDXS) 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. 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.

The Calculation

We're using the 2-stage growth model, which simply means we take in account two stages of company's growth. In the initial period the company may have a higher growth rate and the second stage is usually assumed to have a stable growth rate. 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.

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

	2023	2024	2025	2026	2027	2028	2029	2030	2031	2032
Levered FCF ($, Millions)	-US$78.7m	-US$85.1m	-US$11.5m	US$13.9m	US$21.2m	US$29.1m	US$36.9m	US$44.1m	US$50.3m	US$55.6m
Growth Rate Estimate Source	Analyst x1	Analyst x1	Analyst x1	Analyst x1	Est @ 52.57%	Est @ 37.39%	Est @ 26.77%	Est @ 19.33%	Est @ 14.13%	Est @ 10.48%
Present Value ($, Millions) Discounted @ 7.0%	-US$73.5	-US$74.4	-US$9.4	US$10.6	US$15.2	US$19.5	US$23.1	US$25.7	US$27.5	US$28.4

("Est" = FCF growth rate estimated by Simply Wall St)
Present Value of 10-year Cash Flow (PVCF) = -US$7.0m

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 7.0%.

Terminal Value (TV)= FCF₂₀₃₂ × (1 + g) ÷ (r – g) = US$56m× (1 + 2.0%) ÷ (7.0%– 2.0%) = US$1.1b

Present Value of Terminal Value (PVTV)= TV / (1 + r)¹⁰= US$1.1b÷ ( 1 + 7.0%)¹⁰= US$580m

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$573m. In the final step we divide the equity value by the number of shares outstanding. Compared to the current share price of US$6.3, the company appears a touch undervalued at a 28% 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 Codexis 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 7.0%, which is based on a levered beta of 0.971. 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 Codexis

Looking Ahead:

Whilst important, the DCF calculation is only one of many factors that you need to assess 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. Can we work out why the company is trading at a discount to intrinsic value? For Codexis, we've put together three relevant items you should consider:
