Today we'll do a simple run through of a valuation method used to estimate the attractiveness of AutoZone, Inc. (NYSE:AZO) as an investment opportunity 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. Models like these may appear beyond the comprehension of a lay person, but they're fairly easy to follow.
Companies can be valued in a lot of ways, so we would point out that a DCF is not perfect for every situation. Anyone interested in learning a bit more about intrinsic value should have a read of the Simply Wall St analysis model.
We use what is known as a 2-stage model, which simply means we have two different periods of growth rates for the company's cash flows. Generally the first stage is higher growth, and the second stage is a lower growth phase. In the first stage we need to estimate the cash flows to the business over the next ten years. 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, and so the sum of these future cash flows is then discounted to today's value:

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 a country's GDP growth. In this case we have used the 5-year average of the 10-year government bond yield (2.2%) to estimate future growth. In the same way as with the 10-year 'growth' period, we discount future cash flows to today's value, using a cost of equity of 7.9%.
Present Value of Terminal Value (PVTV)= TV / (1 + r)10= US$65b÷ ( 1 + 7.9%)10= US$30b
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$52b. In the final step we divide the equity value by the number of shares outstanding. Compared to the current share price of US$2.5k, the company appears about fair value at a 16% 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.
NYSE:AZO Discounted Cash Flow January 10th 2024
The Assumptions
Now the most important inputs to a discounted cash flow are the discount rate, and of course, the actual 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 AutoZone 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 7.9%, which is based on a levered beta of 1.144. 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 AutoZone
Strength
Earnings growth over the past year exceeded the industry.
Debt is well covered by earnings and cashflows.
Weakness
Earnings growth over the past year is below its 5-year average.
Opportunity
Annual earnings are forecast to grow for the next 3 years.
Current share price is below our estimate of fair value.
Threat
Total liabilities exceed total assets, which raises the risk of financial distress.
Annual earnings are forecast to grow slower than the American market.
Next Steps:
Whilst important, the DCF calculation ideally won't be the sole piece of analysis you scrutinize for 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. For AutoZone, we've compiled three pertinent items you should explore:
