Why Is STRL 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. Skyrocketing Revenue Shows Strong Momentum
A company’s long-term performance is an indicator of its overall quality. Even a bad business can shine for one or two quarters, but a top-tier one grows for years. Luckily, Sterling’s sales grew at an impressive 11.8% compounded annual growth rate over the last five years. Its growth surpassed the average industrials company and shows its offerings resonate with customers.

2. Excellent Free Cash Flow Margin Boosts Reinvestment Potential
If you’ve followed StockStory for a while, you know we emphasize free cash flow. Why, you ask? We believe that in the end, cash is king, and you can’t use accounting profits to pay the bills.
Sterling has shown terrific cash profitability, putting it in an advantageous position to invest in new products, return capital to investors, and consolidate the market during industry downturns. The company’s free cash flow margin was among the best in the industrials sector, averaging 15.2% over the last five years.

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.
