TopBuild Corp.'s (NYSE:BLD) Intrinsic Value Is Potentially 29% Above Its Share Price

Key Insights

• Using the 2 Stage Free Cash Flow to Equity, TopBuild fair value estimate is US$368
• TopBuild's US$284 share price signals that it might be 23% undervalued
• Our fair value estimate is 3.6% lower than TopBuild's analyst price target of US$382

Today we'll do a simple run through of a valuation method used to estimate the attractiveness of TopBuild Corp. (NYSE:BLD) as an investment opportunity by taking the expected future cash flows and discounting them to their present value. One way to achieve this is by employing the Discounted Cash Flow (DCF) model. Believe it or not, it's not too difficult to follow, as you'll see from our example!

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. If you still have some burning questions about this type of valuation, take a look at the Simply Wall St analysis model.

The Calculation

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 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.

A DCF is all about the idea that a dollar in the future is less valuable than a dollar today, and so the sum of these future cash flows is then discounted to today's value:

10-year free cash flow (FCF) estimate

	2025	2026	2027	2028	2029	2030	2031	2032	2033	2034
Levered FCF ($, Millions)	US$668.4m	US$683.6m	US$667.4m	US$661.9m	US$663.5m	US$670.1m	US$680.3m	US$693.2m	US$708.1m	US$724.6m
Growth Rate Estimate Source	Analyst x4	Analyst x4	Est @ -2.36%	Est @ -0.83%	Est @ 0.24%	Est @ 1.00%	Est @ 1.52%	Est @ 1.89%	Est @ 2.15%	Est @ 2.33%
Present Value ($, Millions) Discounted @ 8.2%	US$618	US$584	US$527	US$483	US$448	US$418	US$392	US$370	US$349	US$330

("Est" = FCF growth rate estimated by Simply Wall St)
Present Value of 10-year Cash Flow (PVCF) = US$4.5b

We now need to calculate the Terminal Value, which accounts for all the future cash flows after this ten year period. The Gordon Growth formula is used to calculate Terminal Value at a future annual growth rate equal to the 5-year average of the 10-year government bond yield of 2.8%. We discount the terminal cash flows to today's value at a cost of equity of 8.2%.

Terminal Value (TV)= FCF₂₀₃₄ × (1 + g) ÷ (r – g) = US$725m× (1 + 2.8%) ÷ (8.2%– 2.8%) = US$14b

Present Value of Terminal Value (PVTV)= TV / (1 + r)¹⁰= US$14b÷ ( 1 + 8.2%)¹⁰= US$6.2b

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$11b. 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$284, the company appears a touch undervalued at a 23% discount to where the stock price trades currently. Valuations are imprecise instruments though, rather like a telescope - move a few degrees and end up in a different galaxy. Do keep this in mind.

The 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 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 8.2%, which is based on a levered beta of 1.254. 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.

Next Steps:

Whilst important, the DCF calculation ideally won't be the sole piece of analysis you scrutinize for 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. Can we work out why the company is trading at a discount to intrinsic value?
