A Look At The Fair Value Of Century Aluminum Company (NASDAQ:CENX)

Key Insights

• Using the 2 Stage Free Cash Flow to Equity, Century Aluminum fair value estimate is US$18.62
• Current share price of US$16.01 suggests Century Aluminum is potentially trading close to its fair value
• The US$14.00 analyst price target for CENX is 25% less than our estimate of fair value

How far off is Century Aluminum Company (NASDAQ:CENX) from its intrinsic value? Using the most recent financial data, we'll take a look at whether the stock is fairly priced by estimating the company's future cash flows and discounting them to their present value. We will take advantage of the Discounted Cash Flow (DCF) model for this purpose. It may sound complicated, but actually it is quite simple!

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 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, 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$77.0m	US$75.3m	US$90.8m	US$102.4m	US$112.2m	US$120.6m	US$127.8m	US$134.0m	US$139.5m	US$144.5m
Growth Rate Estimate Source	Analyst x1	Analyst x1	Analyst x1	Est @ 12.74%	Est @ 9.63%	Est @ 7.46%	Est @ 5.93%	Est @ 4.87%	Est @ 4.12%	Est @ 3.60%
Present Value ($, Millions) Discounted @ 8.6%	US$70.9	US$63.8	US$70.8	US$73.5	US$74.1	US$73.3	US$71.5	US$69.0	US$66.1	US$63.1

("Est" = FCF growth rate estimated by Simply Wall St)
Present Value of 10-year Cash Flow (PVCF) = US$696m

After calculating the present value of future cash flows in the initial 10-year period, we need to calculate the Terminal Value, which accounts for all future cash flows beyond 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 2.4%. We discount the terminal cash flows to today's value at a cost of equity of 8.6%.

Terminal Value (TV)= FCF₂₀₃₃ × (1 + g) ÷ (r – g) = US$145m× (1 + 2.4%) ÷ (8.6%– 2.4%) = US$2.4b

Present Value of Terminal Value (PVTV)= TV / (1 + r)¹⁰= US$2.4b÷ ( 1 + 8.6%)¹⁰= US$1.0b

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$1.7b. In the final step we divide the equity value by the number of shares outstanding. Relative to the current share price of US$16.0, the company appears about fair value at a 14% 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.

The Assumptions

The calculation above is very dependent on two assumptions. The first is the discount rate and the other is the 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 Century Aluminum 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 8.6%, which is based on a levered beta of 1.362. 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 Century Aluminum

Looking Ahead:

Valuation is only one side of the coin in terms of building your investment thesis, and it is only one of many factors that you need to assess for 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?" 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. For Century Aluminum, we've put together three further factors you should further research:
