# Petra Diamonds Limited (LON:PDL) Is Trading At A 23.09% Discount

How far off is Petra Diamonds Limited (LON:PDL) from its intrinsic value? Using the most recent financial data, I am going to 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. I will use the Discounted Cash Flows (DCF) model. Don’t get put off by the jargon, the math behind it is actually quite straightforward. 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 September 2018 so be sure check out the updated calculation by following the link below.

### The calculation

I’m 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 perpetual stable growth rate. In the first stage we need to estimate the cash flows to the business over the next five years. For this I used the consensus of the analysts covering the stock, as you can see below. The sum of these cash flows is then discounted to today’s value.

#### 5-year cash flow estimate

 2019 2020 2021 2022 2023 Levered FCF (\$, Millions) \$96.52 \$108.40 \$89.85 \$92.66 \$95.56 Source Analyst x5 Analyst x5 Analyst x2 Est @ 3.13% Est @ 3.13% Present Value Discounted @ 18.6% \$81.38 \$77.06 \$53.86 \$46.83 \$40.72

Present Value of 5-year Cash Flow (PVCF)= US\$299.8m

We now need to calculate the Terminal Value, which accounts for all the future cash flows after the five years. The Gordon Growth formula is used to calculate Terminal Value at an annual growth rate equal to the 10-year government bond rate of 1.4%. We discount this to today’s value at a cost of equity of 18.6%.

Terminal Value (TV) = FCF2022 × (1 + g) ÷ (r – g) = US\$95.6m × (1 + 1.4%) ÷ (18.6% – 1.4%) = US\$563.2m

Present Value of Terminal Value (PVTV) = TV / (1 + r)5 = US\$563.2m ÷ ( 1 + 18.6%)5 = US\$240.0m

The total value, or equity value, is then the sum of the present value of the cash flows, which in this case is US\$539.8m. To get the intrinsic value per share, we divide this by the total number of shares outstanding, or the equivalent number if this is a depositary receipt or ADR. This results in an intrinsic value in the company’s reported currency of \$0.62. However, PDL’s primary listing is in United Kingdom, and 1 share of PDL in USD represents 0.764 ( USD/ GBP) share of LSE:PDL, so the intrinsic value per share in GBP is £0.48. Relative to the current share price of £0.37, the stock is about right, perhaps slightly undervalued at a 23.1% discount to what it is available for right now.

### The assumptions

The calculation above is very dependent on two assumptions. The first is the discount rate and the other is the cash flows. If you don’t agree with my result, have a go at the calculation yourself and play with the assumptions. Because we are looking at Petra Diamonds 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 18.6%, which is based on a levered beta of 2. 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.

### Next Steps:

Although the valuation of a company is important, it 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 PDL, I’ve put together three fundamental factors you should further research:
