• Investors may be wondering whether TopBuild, at around US$428 a share, still offers value or if most of the opportunity is already reflected in the price.
• The stock has had a mixed run, with a 3.3% decline over the last 7 days, a 22.0% gain over 30 days, a 0.8% decline year to date, and returns of 47.1% over 1 year, 99.1% over 3 years, and 110.8% over 5 years.
• Recent coverage has focused on TopBuild as an established player in insulation and building products, with investors watching how the company positions itself within the broader Consumer Durables space. This backdrop helps explain why the stock's strong multi year returns sit alongside shorter term pullbacks, as expectations and perceived risk adjust.
• Simply Wall St currently gives TopBuild a valuation score of 1 out of 6. The rest of this article will walk through what different valuation approaches say about the stock and finish with a more holistic way to think about value that goes beyond any single model.

TopBuild scores just 1/6 on our valuation checks. See what other red flags we found in the full valuation breakdown.

Approach 1: TopBuild Discounted Cash Flow (DCF) Analysis

A Discounted Cash Flow, or DCF, model estimates what a stock could be worth today by projecting future cash flows and discounting them back to a single present value figure.

For TopBuild, the model uses a 2 Stage Free Cash Flow to Equity approach, starting from last twelve months free cash flow of about $697.8 million. Analysts provide explicit estimates for several years, and Simply Wall St then extrapolates further to create a ten year path. By 2035, projected free cash flow is $921.8 million, still under $1b, so the model stays in the hundreds of millions range throughout the forecast period.

Bringing all those projected cash flows back to today results in an estimated intrinsic value of about $443.18 per share. With the current share price around $428, the DCF output implies the stock trades at roughly a 3.4% discount to this estimate, which sits well within a reasonable margin of error.

Result: ABOUT RIGHT

TopBuild is fairly valued according to our Discounted Cash Flow (DCF), but this can change at a moment's notice. Track the value in your watchlist or portfolio and be alerted on when to act.

Approach 2: TopBuild Price vs Earnings

For profitable companies, the P/E ratio is a useful way to link what you pay for each share to the earnings that support that price. It gives a quick sense of how many dollars investors are paying for each dollar of current earnings.

What counts as a “normal” or “fair” P/E depends on how the market views a company’s growth prospects and risk. Higher expected growth or lower perceived risk can support a higher P/E, while slower growth or higher risk usually lines up with a lower P/E.

TopBuild currently trades on a P/E of 23.8x. That is above the Consumer Durables industry average P/E of 12.4x and higher than the peer group average of 14.4x. Simply Wall St also calculates a “Fair Ratio” of 20.8x, which is the P/E that would be expected given factors such as TopBuild’s earnings profile, industry, profit margins, market cap and risk attributes.

This Fair Ratio is more tailored than simple peer or industry comparisons because it adjusts for company specific characteristics rather than assuming all Consumer Durables stocks should trade on similar multiples. Compared with the actual P/E of 23.8x, the 20.8x Fair Ratio points to TopBuild trading at a premium.

Result: OVERVALUED

Upgrade Your Decision Making: Choose your TopBuild Narrative

Earlier it was mentioned that there is an even better way to understand valuation. This is where Narratives come in, giving you a simple way to link your view of TopBuild’s story to a financial forecast and then to a fair value that you can compare with the current share price.

On Simply Wall St’s Community page, Narratives let you plug in assumptions for future revenue, earnings and margins, then connect those to a fair value estimate that updates automatically when new information such as earnings or merger news is reflected in the data.

This framework helps you consider your options when price and fair value do not line up. For example, if your Narrative suggests TopBuild is closer to the higher US$520 analyst target or the lower US$390 target, you can clearly see whether your story implies the stock is priced above or below what you think it is worth.

For TopBuild however we'll make it really easy for you with previews of two leading TopBuild Narratives:

Fair value in this narrative: about US$478.91 per share.

Gap to that fair value: around 10.6% above the recent US$428.03 share price.

Revenue growth used in the narrative: 7.31% a year.

• Analysts see a broader mix across commercial, industrial and retrofit work, which is expected to make revenue less tied to new housing cycles.
• They model steady revenue growth with slightly lower margins and expect earnings and buybacks to support earnings per share by the late 2020s.
• The analyst consensus price target of US$478.91 is only modestly above the recent share price, so this view frames TopBuild as close to fairly priced on their assumptions.

Fair value in this narrative: US$390.00 per share.

Premium to that fair value: about 9.8% above the bearish estimate.

Revenue growth used in the narrative: 7.92% a year.

• This narrative leans on concerns that heavy use of acquisitions, higher debt and interest costs, and project based exposure could leave earnings more fragile than the market expects.
• Bearing analysts still factor in higher revenue and earnings over time, but assume a lower future P/E of 20.3x compared with today.
• On their numbers, the gap between the assumed fair value of US$390.00 and the recent price of US$428.03 implies the stock is pricing in more optimism than this cautious view supports.
