Terminal Value (TV)= FCF₂₀₃₄ × (1 + g) ÷ (r – g) = US$1.0b× (1 + 2.5%) ÷ (7.3%– 2.5%) = US$22b

Present Value of Terminal Value (PVTV)= TV / (1 + r)¹⁰= US$22b÷ ( 1 + 7.3%)¹⁰= US$11b

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$16b. To get the intrinsic value per share, we divide this by the total number of shares outstanding. Relative to the current share price of US$45.1, the company appears quite good value at a 50% 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

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 Summit Materials 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 7.3%, which is based on a levered beta of 1.174. 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 Summit Materials

Strength

• Earnings growth over the past year exceeded the industry.

Weakness

• Interest payments on debt are not well covered.

• Shareholders have been diluted in the past year.

Opportunity

• Annual earnings are forecast to grow faster than the American market.

• Trading below our estimate of fair value by more than 20%.

Threat

• Debt is not well covered by operating cash flow.

• Revenue is forecast to grow slower than 20% per year.

Next Steps:

Whilst important, the DCF calculation shouldn't be the only metric you look at when researching a company. The DCF model is not a perfect stock valuation tool. 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. Can we work out why the company is trading at a discount to intrinsic value? For Summit Materials, we've compiled three pertinent factors you should consider:

1. Risks: We feel that you should assess the 3 warning signs for Summit Materials (1 is a bit unpleasant!) we've flagged before making an investment in the company.
