A Look At The Intrinsic Value Of TopBuild Corp. (NYSE:BLD)

Key Insights

• The projected fair value for TopBuild is US$420 based on 2 Stage Free Cash Flow to Equity
• Current share price of US$434 suggests TopBuild is potentially trading close to its fair value
• Our fair value estimate is 6.0% lower than TopBuild's analyst price target of US$447

In this article we are going to estimate the intrinsic value of TopBuild Corp. (NYSE:BLD) by estimating the company's future cash flows and discounting them to their present value. We will take advantage of the Discounted Cash Flow (DCF) model for this purpose. It may sound complicated, but actually it is quite simple!

We generally believe that a company's value is the present value of all of the cash it will generate in the future. However, a DCF is just one valuation metric among many, and it is not without flaws. For those who are keen learners of equity analysis, the Simply Wall St analysis model here may be something of interest to you.

Crunching The Numbers

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 start off with, we need to estimate 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 discount the value of these future cash flows to their estimated value in today's dollars:

Present Value of 10-year Cash Flow (PVCF) = US$4.9b

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 (3.1%) 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 8.7%.

Terminal Value (TV)= FCF₂₀₃₅ × (1 + g) ÷ (r – g) = US$848m× (1 + 3.1%) ÷ (8.7%– 3.1%) = US$16b

Present Value of Terminal Value (PVTV)= TV / (1 + r)¹⁰= US$16b÷ ( 1 + 8.7%)¹⁰= US$6.8b

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$12b. 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$434, the company appears around fair value at the time of writing. 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. 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 TopBuild 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 8.7%, which is based on a levered beta of 1.207. 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.

Whilst important, the DCF calculation shouldn't be the only metric you look at when researching a company. DCF models are not the be-all and end-all of investment valuation. 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. 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.
