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.

Duolingo has shown terrific cash profitability, driven by its lucrative business model and cost-effective customer acquisition strategy that enable it to stay ahead of the competition through investments in new products rather than sales and marketing. The company’s free cash flow margin was among the best in the consumer internet sector, averaging an eye-popping 35% over the last two years.
