Revenue Growth
A company’s long-term performance is an indicator of its overall quality. Any business can experience short-term success, but top-performing ones enjoy sustained growth for years. Thankfully, Installed Building Products’s 11.7% annualized revenue growth over the last five years was impressive. Its growth beat the average industrials company and shows its offerings resonate with customers, a helpful starting point for our analysis.
We at StockStory place the most emphasis on long-term growth, but within industrials, a half-decade historical view may miss cycles, industry trends, or a company capitalizing on catalysts such as a new contract win or a successful product line. Installed Building Products’s recent performance shows its demand has slowed significantly as its annualized revenue growth of 2.4% over the last two years was well below its five-year trend. 
This quarter, Installed Building Products missed Wall Street’s estimates and reported a rather uninspiring 3.5% year-on-year revenue decline, generating $660.5 million of revenue.
Looking ahead, sell-side analysts expect revenue to grow 2.4% over the next 12 months, similar to its two-year rate. This projection doesn't excite us and indicates its newer products and services will not catalyze better top-line performance yet. At least the company is tracking well in other measures of financial health.

Operating Margin
Operating margin is an important measure of profitability as it shows the portion of revenue left after accounting for all core expenses – everything from the cost of goods sold to advertising and wages. It’s also useful for comparing profitability across companies with different levels of debt and tax rates because it excludes interest and taxes.
Installed Building Products has been an efficient company over the last five years. It was one of the more profitable businesses in the industrials sector, boasting an average operating margin of 12.5%.
Looking at the trend in its profitability, Installed Building Products’s operating margin rose by 2.6 percentage points over the last five years, as its sales growth gave it operating leverage. Its expansion was impressive, especially when considering most Home Builders peers saw their margins plummet.
This quarter, Installed Building Products generated an operating margin profit margin of 8.7%, down 1.5 percentage points year on year. Since Installed Building Products’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
Revenue trends explain a company’s historical growth, but the long-term change in earnings per share (EPS) points to the profitability of that growth – for example, a company could inflate its sales through excessive spending on advertising and promotions.
Installed Building Products’s EPS grew at 20.1% compounded annual growth rate over the last five years, higher than its 11.7% annualized revenue growth. This tells us the company became more profitable on a per-share basis as it expanded.
We can take a deeper look into Installed Building Products’s earnings quality to better understand the drivers of its performance. As we mentioned earlier, Installed Building Products’s operating margin declined this quarter but expanded by 2.6 percentage points over the last five years. Its share count also shrank by 8.9%, and these factors together are positive signs for shareholders because improving profitability and share buybacks turbocharge EPS growth relative to revenue growth. 
Like with revenue, we analyze EPS over a more recent period because it can provide insight into an emerging theme or development for the business.
