Why Is Sterling a Good Business?
Involved in the construction of a major highway, the Grand Parkway in Houston, TX, Sterling Infrastructure (NASDAQ:STRL) provides civil infrastructure construction.
1. Long-Term Revenue Growth Shows Strong Momentum
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. Thankfully, Sterling’s 9.9% annualized revenue growth over the last five years was solid. Its growth surpassed the average industrials company and shows its offerings resonate with customers.

2. Increasing Free Cash Flow Margin Juices Financials
Free cash flow isn't a prominently featured metric in company financials and earnings releases, but we think it's telling because it accounts for all operating and capital expenses, making it tough to manipulate. Cash is king.
As you can see below, Sterling’s margin expanded by 12.1 percentage points over the last five years. This is encouraging, and we can see it became a less capital-intensive business because its free cash flow profitability rose more than its operating profitability. Sterling’s free cash flow margin for the trailing 12 months was 20.4%.

3. New Investments Bear Fruit as ROIC Jumps
A company’s ROIC, or return on invested capital, shows how much operating profit it makes compared to the money it has raised (debt and equity).
We like to invest in businesses with high returns, but the trend in a company’s ROIC is what often surprises the market and moves the stock price. Over the last few years, Sterling’s ROIC has increased significantly. This is a great sign when paired with its already strong returns. It could suggest its competitive advantage or profitable growth opportunities are expanding.
