Does the January share price for Tortilla Mexican Grill plc (LON:MEX) reflect what it’s really worth? Today, we will estimate the stock’s intrinsic value by estimating the company’s future cash flows and discounting them to their present value. This will be done using the Discounted Cash Flow (DCF) model. Before you think you won’t be able to understand it, just read on! It’s actually much less complex than you’d imagine.

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 want to learn more about discounted cash flow, the rationale behind this calculation can be read in detail in the Simply Wall St analysis model.

The Calculation

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 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 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, so we need to discount the sum of these future cash flows to arrive at a present value estimate:

(“Est” = FCF growth rate estimated by Simply Wall St)
Present Value of 10-year Cash Flow (PVCF) = UK£25m

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 1.0%. We discount the terminal cash flows to today’s value at a cost of equity of 11%.

Terminal Value (TV)= FCF2032 × (1 + g) ÷ (r – g) = UK£13m× (1 + 1.0%) ÷ (11%– 1.0%) = UK£131m

Present Value of Terminal Value (PVTV)= TV / (1 + r)10= UK£131m÷ ( 1 + 11%)10= UK£45m

The total value, or equity value, is then the sum of the present value of the future cash flows, which in this case is UK£71m. In the final step we divide the equity value by the number of shares outstanding. Relative to the current share price of UK£1.0, the company appears quite undervalued at a 45% discount to where the stock price trades currently. Valuations are imprecise instruments though, rather like a telescope – move a few degrees and end up in a different galaxy. Do keep this in mind.

The Assumptions

Now the most important inputs to a discounted cash flow are the discount rate, and of course, the actual cash flows. Part of investing is coming up with your own evaluation of a company’s future performance, so try the calculation yourself and check your own 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 Tortilla Mexican Grill 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 11%, which is based on a levered beta of 1.489. 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.

SWOT Analysis for Tortilla Mexican Grill

Strength

  • Debt is well covered by cash flow.
Weakness

  • Interest payments on debt are not well covered.
Opportunity

  • Forecast to reduce losses next year.
  • Has sufficient cash runway for more than 3 years based on current free cash flows.
  • Good value based on P/S ratio and estimated fair value.
Threat

  • No apparent threats visible for MEX.

Next Steps:

Valuation is only one side of the coin in terms of building your investment thesis, and it shouldn’t be the only metric you look at when researching a company. The DCF model is not a perfect stock valuation tool. Instead the best use for a DCF model is to test certain assumptions and theories to see if they would lead to the company being undervalued or overvalued. For instance, if the terminal value growth rate is adjusted slightly, it can dramatically alter the overall result. Why is the intrinsic value higher than the current share price? For Tortilla Mexican Grill, we’ve put together three additional factors you should assess:

  1. Risks: We feel that you should assess the 1 warning sign for Tortilla Mexican Grill we’ve flagged before making an investment in the company.
