Fortune’s Methodology
Fortune’s list recognizes the world’s top performers based on sustained financial performance across three critical factors. Nu’s ranking is derived from a rigorous evaluation of Revenue Growth Rate, EPS (Earnings Per Share) Growth Rate, and Three-Year Annualized Total Return (for the period ended June 30, 2025). The list includes only companies that meet strict qualification criteria, including: trading on a major U.S. stock exchange since at least June 30, 2022; having minimum four-quarter revenue of $50 million and net income of $10 million (ended on or before April 30, 2025); and posting at least 20% annualized growth in revenue and EPS over the three-year period.The final rank is based on an equally weighted sum of the three performance variables, with data provided by Zacks Investment Research and S&P Global Market Intelligence.
