Today we will run through one way of estimating the intrinsic value of Atlantica Sustainable Infrastructure plc (NASDAQ:AY) by projecting its future cash flows and then discounting them to today's value. The Discounted Cash Flow (DCF) model is the tool we will apply to do this. Don't get put off by the jargon, the math behind it is actually quite straightforward.

Remember though, that there are many ways to estimate a company's value, and a DCF is just one method. Anyone interested in learning a bit more about intrinsic value should have a read of the Simply Wall St analysis model.

The method

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. Seeing as no analyst estimates of free cash flow are available to us, we have extrapolate the previous free cash flow (FCF) from the company's last 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

2021 2022 2023 2024 2025 2026 2027 2028 2029 2030
Levered FCF ($, Millions) US$372.3m US$364.6m US$361.7m US$362.1m US$364.8m US$369.1m US$374.6m US$381.0m US$388.1m US$395.8m
Growth Rate Estimate Source Est @ -3.93% Est @ -2.09% Est @ -0.79% Est @ 0.11% Est @ 0.74% Est @ 1.19% Est @ 1.5% Est @ 1.71% Est @ 1.87% Est @ 1.97%
Present Value ($, Millions) Discounted @ 9.2% US$341 US$306 US$278 US$255 US$235 US$218 US$203 US$189 US$176 US$165

("Est" = FCF growth rate estimated by Simply Wall St)
Present Value of 10-year Cash Flow (PVCF) = US$2.4b

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 9.2%.

Terminal Value (TV)= FCF2030 × (1 + g) ÷ (r – g) = US$396m× (1 + 2.2%) ÷ (9.2%– 2.2%) = US$5.8b

Present Value of Terminal Value (PVTV)= TV / (1 + r)10= US$5.8b÷ ( 1 + 9.2%)10= US$2.4b

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$4.8b. The last step is to then divide the equity value by the number of shares outstanding. Relative to the current share price of US$35.2, the company appears a touch undervalued at a 25% discount to where the stock price trades currently. Remember though, that this is just an approximate valuation, and like any complex formula - garbage in, garbage out.

Important 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 Atlantica Sustainable Infrastructure 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 9.2%, which is based on a levered beta of 1.005. 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.

Looking Ahead:

Although the valuation of a company is important, it shouldn't be the only metric you look at when researching a company. The DCF model is not a perfect stock valuation tool. Preferably you'd apply different cases and assumptions and see how they would impact the company's valuation. If a company grows at a different rate, or if its cost of equity or risk free rate changes sharply, the output can look very different. Why is the intrinsic value higher than the current share price? For Atlantica Sustainable Infrastructure, there are three pertinent aspects you should consider:

  1. Risks: Consider for instance, the ever-present spectre of investment risk. We've identified 3 warning signs with Atlantica Sustainable Infrastructure (at least 2 which are potentially serious) , and understanding these should be part of your investment process.
