Why Is O'Reilly a Good Business?
Serving both the DIY customer and professional mechanic, O’Reilly Automotive (NASDAQ: ORLY) is an auto parts and accessories retailer that sells everything from fuel pumps to car air fresheners to mufflers.
1. Surging Same-Store Sales Show Increasing Demand
Same-store sales show the change in sales for a retailer's e-commerce platform and brick-and-mortar shops that have existed for at least a year. This is a key performance indicator because it measures organic growth.
O'Reilly has been one of the most successful retailers over the last two years thanks to skyrocketing demand within its existing locations. On average, the company has posted exceptional year-on-year same-store sales growth of 4.5%.

2. Elite Gross Margin Powers Best-In-Class Business Model
We prefer higher gross margins because they not only make it easier to generate more operating profits but also indicate product differentiation, negotiating leverage, and pricing power.
O'Reilly has best-in-class unit economics for a retailer, enabling it to invest in areas such as marketing and talent. As you can see below, it averaged an elite 51.3% gross margin over the last two years. That means O'Reilly only paid its suppliers $48.74 for every $100 in revenue.
3. 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.

The company’s free cash flow margin was among the best in the consumer retail sector, averaging 12% over the last two years.
