An Intrinsic Calculation For Fortuna Silver Mines Inc. (TSE:FVI) Suggests It's 48% Undervalued

Today we will run through one way of estimating the intrinsic value of Fortuna Silver Mines Inc. (TSE:FVI) by taking the forecast future cash flows of the company and discounting them back to today's value. This will be done using the Discounted Cash Flow (DCF) model. There's really not all that much to it, even though it might appear quite complex.

We would caution that there are many ways of valuing a company and, like the DCF, each technique has advantages and disadvantages in certain scenarios. If you still have some burning questions about this type of valuation, take a look at the Simply Wall St analysis model.

The Model

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. 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.

Generally we assume that a dollar today is more valuable than a dollar in the future, 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

	2023	2024	2025	2026	2027	2028	2029	2030	2031	2032
Levered FCF ($, Millions)	US$129.5m	US$220.4m	US$134.0m	US$92.6m	US$73.0m	US$62.5m	US$56.6m	US$53.1m	US$51.0m	US$49.9m
Growth Rate Estimate Source	Analyst x5	Analyst x4	Analyst x1	Est @ -30.92%	Est @ -21.16%	Est @ -14.32%	Est @ -9.54%	Est @ -6.19%	Est @ -3.84%	Est @ -2.2%
Present Value ($, Millions) Discounted @ 6.9%	US$121	US$193	US$110	US$70.9	US$52.3	US$41.9	US$35.5	US$31.1	US$28.0	US$25.6

("Est" = FCF growth rate estimated by Simply Wall St)
Present Value of 10-year Cash Flow (PVCF) = US$709m

We now need to calculate the Terminal Value, which accounts for all the future cash flows after this ten year period. 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 1.6%. We discount the terminal cash flows to today's value at a cost of equity of 6.9%.

Terminal Value (TV)= FCF₂₀₃₂ × (1 + g) ÷ (r – g) = US$50m× (1 + 1.6%) ÷ (6.9%– 1.6%) = US$963m

Present Value of Terminal Value (PVTV)= TV / (1 + r)¹⁰= US$963m÷ ( 1 + 6.9%)¹⁰= US$495m

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$1.2b. The last step is to then divide the equity value by the number of shares outstanding. Compared to the current share price of CA$2.9, the company appears quite undervalued at a 48% 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.

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 these result, have a go at the calculation yourself and play with the 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 Fortuna Silver Mines 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 6.9%, which is based on a levered beta of 1.242. 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.

Moving On:

Whilst important, the DCF calculation shouldn't be the only metric you look at when researching a company. DCF models are not the be-all and end-all of investment valuation. Rather it should be seen as a guide to "what assumptions need to be true for this stock to be under/overvalued?" For example, changes in the company's cost of equity or the risk free rate can significantly impact the valuation. Why is the intrinsic value higher than the current share price?
