Company Overview

Established in 2015 following a spinoff from Masco Corporation, TopBuild (NYSE: BLD) is a distributor and installer of insulation and other building products.

Revenue Growth

Examining a company’s long-term performance can provide clues about its quality. Any business can experience short-term success, but top-performing ones enjoy sustained growth for years. Thankfully, TopBuild’s 14.9% annualized revenue growth over the last five years was exceptional. Its growth beat the average industrials company and shows its offerings resonate with customers.

Long-term growth is the most important, but within industrials, a half-decade historical view may miss new industry trends or demand cycles. TopBuild’s recent performance shows its demand has slowed significantly as its annualized revenue growth of 3.9% over the last two years was well below its five-year trend.

This quarter, TopBuild reported year-on-year revenue growth of 17.2%, and its $1.45 billion of revenue exceeded Wall Street’s estimates by 2.5%.

Looking ahead, sell-side analysts expect revenue to grow 8.3% over the next 12 months, an improvement versus the last two years. This projection is above the sector average and indicates its newer products and services will catalyze better top-line performance.

Operating Margin

Operating margin is a key measure of profitability. Think of it as net income - the bottom line - excluding the impact of taxes and interest on debt, which are less connected to business fundamentals.

TopBuild’s operating margin has generally stayed the same over the last 12 months, averaging 15.6% over the last five years. This profitability was top-notch for an industrials business, showing it’s an well-run company with an efficient cost structure. This result was particularly impressive because of its low gross margin, which is mostly a factor of what it sells and takes huge shifts to move meaningfully. Companies have more control over their operating margins, and it’s a show of well-managed operations if they’re high when gross margins are low.

Looking at the trend in its profitability, TopBuild’s operating margin might fluctuated slightly but has generally stayed the same over the last five years. We like to see margin expansion, but we’re still happy with TopBuild’s performance considering most Home Builders companies saw their margins plummet.

In Q1, TopBuild generated an operating margin profit margin of 12.1%, down 2.3 percentage points year on year. Since TopBuild’s operating margin decreased more than its gross margin, we can assume it was less efficient because expenses such as marketing, R&D, and administrative overhead increased.

Earnings Per Share

We track the long-term change in earnings per share (EPS) for the same reason as long-term revenue growth. Compared to revenue, however, EPS highlights whether a company’s growth is profitable.

TopBuild’s EPS grew at 18.9% compounded annual growth rate over the last five years, higher than its 14.9% annualized revenue growth. However, this alone doesn’t tell us much about its business quality because its operating margin didn’t improve.

We can take a deeper look into TopBuild’s earnings quality to better understand the drivers of its performance. A five-year view shows that TopBuild has repurchased its stock, shrinking its share count by 15.3%. This tells us its EPS outperformed its revenue not because of increased operational efficiency but financial engineering, as buybacks boost per share earnings.

Like with revenue, we analyze EPS over a shorter period to see if we are missing a change in the business.

For TopBuild, its two-year annual EPS declines of 3.2% mark a reversal from its (seemingly) healthy five-year trend. We hope TopBuild can return to earnings growth in the future.

In Q1, TopBuild reported adjusted EPS of $3.75, down from $4.63 in the same quarter last year. Despite falling year on year, this print beat analysts’ estimates by 2.9%. Over the next 12 months, Wall Street expects TopBuild’s full-year EPS of $18.92 to shrink by 1.2%.

Key Takeaways from TopBuild’s Q1 Results

We enjoyed seeing TopBuild beat analysts’ revenue expectations this quarter. We were also happy its adjusted operating income outperformed Wall Street’s estimates. Overall, we think this was a decent quarter with some key metrics above expectations. The stock traded up 1.1% to $435.22 immediately after reporting.

TopBuild had an encouraging quarter, but one earnings result doesn’t necessarily make the stock a buy. Let’s see if this is a good investment. When making that decision, it’s important to consider its valuation, business qualities, as well as what has happened in the latest quarter.
