An Intrinsic Calculation For AK Steel Holding Corporation (NYSE:AKS) Suggests It's 46% Undervalued

In this article we are going to estimate the intrinsic value of AK Steel Holding Corporation (NYSE:AKS) by projecting its future cash flows and then discounting them to today's value. I will be using the Discounted Cash Flow (DCF) model. Don't get put off by the jargon, the math behind it is actually quite straightforward.

Companies can be valued in a lot of ways, so we would point out that a DCF is not perfect for every situation. Anyone interested in learning a bit more about intrinsic value should have a read of the Simply Wall St analysis model.

The calculation

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 are 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:

Present Value of 10-year Cash Flow (PVCF)= $919.25m

"Est" = FCF growth rate estimated by Simply Wall St

After calculating the present value of future cash flows in the intial 10-year period, we need to calculate the Terminal Value, which accounts for all future cash flows beyond 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 10-year government bond rate (2.7%) 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 14.7%.

Terminal Value (TV) = FCF2029 × (1 + g) ÷ (r – g) = US$217m × (1 + 2.7%) ÷ (14.7% – 2.7%) = US$1.9b

Present Value of Terminal Value (PVTV) = TV / (1 + r)10 = $US$1.9b ÷ ( 1 + 14.7%)10 = $476.85m

The total value, or equity value, is then the sum of the present value of the future cash flows, which in this case is $1.40b. To get the intrinsic value per share, we divide this by the total number of shares outstanding. This results in an intrinsic value estimate of $4.41. Compared to the current share price of $2.37, the company appears quite undervalued at a 46% discount to what it is available for right now. 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 AK Steel Holding 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 14.7%, which is based on a levered beta of 2. 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:

Whilst important, 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?" 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. What is the reason for the share price to differ from the intrinsic value? For AK Steel Holding, I've compiled three essential aspects you should further research:
