Key Insights

• Using the 2 Stage Free Cash Flow to Equity, Acuity Brands fair value estimate is US$281

• Acuity Brands' US$239 share price indicates it is trading at similar levels as its fair value estimate

• The US$233 analyst price target for AYI is 17% less than our estimate of fair value

In this article we are going to estimate the intrinsic value of Acuity Brands, Inc. (NYSE:AYI) by taking the forecast future cash flows of the company and discounting them back to today's value. Our analysis will employ 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 still have some burning questions about this type of valuation, take a look at the Simply Wall St analysis model.

What's The Estimated Valuation?

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. 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.

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:

10-year free cash flow (FCF) forecast

	2024	2025	2026	2027	2028	2029	2030	2031	2032	2033
Levered FCF ($, Millions)	US$468.3m	US$491.9m	US$528.2m	US$535.6m	US$544.5m	US$554.4m	US$565.2m	US$576.6m	US$588.6m	US$601.1m
Growth Rate Estimate Source	Analyst x5	Analyst x5	Analyst x1	Est @ 1.41%	Est @ 1.65%	Est @ 1.82%	Est @ 1.94%	Est @ 2.03%	Est @ 2.08%	Est @ 2.12%
Present Value ($, Millions) Discounted @ 8.0%	US$434	US$422	US$420	US$394	US$371	US$350	US$330	US$312	US$295	US$279

("Est" = FCF growth rate estimated by Simply Wall St)
Present Value of 10-year Cash Flow (PVCF) = US$3.6b

We now need to calculate the Terminal Value, which accounts for all the future cash flows after this ten year period. 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 8.0%.

Terminal Value (TV)= FCF₂₀₃₃ × (1 + g) ÷ (r – g) = US$601m× (1 + 2.2%) ÷ (8.0%– 2.2%) = US$11b

Present Value of Terminal Value (PVTV)= TV / (1 + r)¹⁰= US$11b÷ ( 1 + 8.0%)¹⁰= US$5.0b

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$8.6b. To get the intrinsic value per share, we divide this by the total number of shares outstanding. Compared to the current share price of US$239, the company appears about fair value at a 15% 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. 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 Acuity Brands 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 8.0%, which is based on a levered beta of 1.149. 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:

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. It's not possible to obtain a foolproof valuation with a DCF model. 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 Acuity Brands, we've compiled three further elements you should explore:

1. Risks: We feel that you should assess the 1 warning sign for Acuity Brands we've flagged before making an investment in the company.
