It's often helpful to take a look at earnings before interest and tax (EBIT) margins, as well as revenue growth, to get another take on the quality of the company's growth. Our analysis has highlighted that Cintas' revenue from operations did not account for all of their revenue in the previous 12 months, so our analysis of its margins might not accurately reflect the underlying business. Cintas maintained stable EBIT margins over the last year, all while growing revenue 11% to US$9.0b. That's encouraging news for the company!
