Calculating The Intrinsic Value Of Zimplats Holdings Limited (ASX:ZIM)

Today we will run through one way of estimating the intrinsic value of Zimplats Holdings Limited (ASX:ZIM) by taking the expected future cash flows and discounting them to their present value. The Discounted Cash Flow (DCF) model is the tool we will apply to do this. Believe it or not, it's not too difficult to follow, as you'll see from our example!

Companies can be valued in a lot of ways, so we would point out that a DCF is not perfect for every situation. 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'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. To start off with, we need to estimate the next ten years of cash flows. Seeing as no analyst estimates of free cash flow are available to us, we have extrapolate the previous free cash flow (FCF) from the company's last 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.

Generally we assume that a dollar today is more valuable than a dollar in the future, and so the sum of these future cash flows is then discounted to today's value:

	2021	2022	2023	2024	2025	2026	2027	2028	2029	2030
Levered FCF ($, Millions)	US$97.6m	US$90.3m	US$86.2m	US$84.0m	US$83.1m	US$83.1m	US$83.6m	US$84.5m	US$85.8m	US$87.2m
Growth Rate Estimate Source	Est @ -11.64%	Est @ -7.47%	Est @ -4.55%	Est @ -2.51%	Est @ -1.08%	Est @ -0.08%	Est @ 0.62%	Est @ 1.12%	Est @ 1.46%	Est @ 1.7%
Present Value ($, Millions) Discounted @ 8.8%	US$89.7	US$76.3	US$66.9	US$60.0	US$54.5	US$50.1	US$46.3	US$43.1	US$40.2	US$37.5

("Est" = FCF growth rate estimated by Simply Wall St)
Present Value of 10-year Cash Flow (PVCF) = US$564m

The second stage is also known as Terminal Value, this is the business's cash flow after 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 2.3%. We discount the terminal cash flows to today's value at a cost of equity of 8.8%.

Terminal Value (TV)= FCF₂₀₃₀ × (1 + g) ÷ (r – g) = US$87m× (1 + 2.3%) ÷ (8.8%– 2.3%) = US$1.4b

Present Value of Terminal Value (PVTV)= TV / (1 + r)¹⁰= US$1.4b÷ ( 1 + 8.8%)¹⁰= US$588m

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$1.2b. The last step is to then divide the equity value by the number of shares outstanding. Relative to the current share price of AU$11.7, the company appears about fair value at a 19% discount to where the stock price trades currently. The assumptions in any calculation have a big impact on the valuation, so it is better to view this as a rough estimate, not precise down to the last cent.

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 Zimplats Holdings 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 8.8%, which is based on a levered beta of 1.087. 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 ideally won't be the sole piece of analysis you scrutinize for a company. It's not possible to obtain a foolproof valuation with a DCF model. 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.
