Today I will be providing a simple run through of a valuation method used to estimate the attractiveness of Perseus Mining Limited (ASX:PRU) as an investment opportunity by taking the foreast future cash flows of the company and discounting them back to today’s value. I will use the discounted cash flows (DCF) model. It may sound complicated, but actually it is quite simple! If you want to learn more about discounted cash flow, the basis for my calcs can be read in detail in the Simply Wall St analysis model. Please also note that this article was written in August 2018 so be sure check out the updated calculation by following the link below.

Crunching the numbers

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 five years of cash flows. For this I used the consensus of the analysts covering the stock, as you can see below. I then discount this to its value today and sum up the total to get the present value of these cash flows.

5-year cash flow estimate

Present Value of 5-year Cash Flow (PVCF)= AU$99.5m

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 the GDP. In this case I have used the 10-year government bond rate (2.8%). In the same way as with the 5-year ‘growth’ period, we discount this to today’s value at a cost of equity of 10.1%.

Terminal Value (TV) = FCF₂₀₂₂ × (1 + g) ÷ (r – g) = AU$68.2m × (1 + 2.8%) ÷ (10.1% – 2.8%) = AU$951.5m

Present Value of Terminal Value (PVTV) = TV / (1 + r)⁵ = AU$951.5m ÷ ( 1 + 10.1%)⁵ = AU$587.0m

The total value is the sum of cash flows for the next five years and the discounted terminal value, which results in the Total Equity Value, which in this case is AU$686.4m. The last step is to then divide the equity value by the number of shares outstanding. If the stock is an depositary receipt (represents a specified number of shares in a foreign corporation) then we use the equivalent number. This results in an intrinsic value of A$0.66. Relative to the current share price of A$0.35, the stock is quite undervalued at a 47.7% discount to what it is available for right now.

Important assumptions

Now 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 my inputs, I recommend redoing the calculations yourself and playing with them. Because we are looking at Perseus Mining as potential shareholders, the cost of equity is used as the discount rate, rather than the cost of capital (or weighed average cost of capital, WACC) which accounts for debt. In this calculation I’ve used 10.1%, which is based on a levered beta of 1.02. This is derived from the Bottom-Up Beta method based on comparable companies, with an imposed limit between 0.8 and 2.0, which is a reasonable range for a stable business.

Whilst important, DCF calculation shouldn’t be the only metric you look at when researching a company. What is the reason for the share price to differ from the intrinsic value? For PRU, I’ve put together three key factors you should further examine:
