Revenue Growth
A company’s long-term performance is an indicator of its overall quality. Any business can put up a good quarter or two, but the best consistently grow over the long haul. Unfortunately, Builders FirstSource struggled to consistently increase demand as its $14.45 billion of sales for the trailing 12 months was close to its revenue five years ago. This was below our standards and suggests it’s a low quality business.
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. Builders FirstSource’s recent performance shows its demand remained suppressed as its revenue has declined by 7.9% annually over the last two years. 
We can dig further into the company’s revenue dynamics by analyzing its most important segments, Manufactured products
and Windows, doors & millwork
, which are 21.5% and 24.7% of revenue. Over the last two years, Builders FirstSource’s Manufactured products
revenue (floors, wall panels, and engineered wood) averaged 13.9% year-on-year declines while its Windows, doors & millwork
revenue (self explanatory) averaged 8.5% declines. 
This quarter, Builders FirstSource missed Wall Street’s estimates and reported a rather uninspiring 8.8% year-on-year revenue decline, generating $3.86 billion of revenue.
Looking ahead, sell-side analysts expect revenue to grow 5.2% over the next 12 months. While this projection suggests its newer products and services will fuel better top-line performance, it is still below the sector average.

Since Builders FirstSource’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.
Sadly for Builders FirstSource, its EPS declined by 5.7% annually over the last five years while its revenue was flat. This tells us the company struggled because its fixed cost base made it difficult to adjust to choppy demand.
We can take a deeper look into Builders FirstSource’s earnings to better understand the drivers of its performance.
