Why Is DUOL a Good Business?
Founded by a Carnegie Mellon computer science professor and his Ph.D. student, Duolingo (NASDAQ:DUOL) is a mobile app helping people learn new languages.
1. Monthly Active Users Skyrocket, Fueling Growth Opportunities
As a subscription-based app, Duolingo generates revenue growth by expanding both its subscriber base and the amount each subscriber spends over time.
Over the last two years, Duolingo’s monthly active users, a key performance metric for the company, increased by 41.5% annually to 116.7 million in the latest quarter. This growth rate is among the fastest of any consumer internet business and indicates its offerings have significant traction.
2. Outstanding Long-Term EPS Growth
We track the change in earnings per share (EPS) because it highlights whether a company’s growth is profitable.
Duolingo’s EPS grew at an astounding 210% compounded annual growth rate over the last three years, higher than its 44% annualized revenue growth. This tells us the company became more profitable on a per-share basis as it expanded.

3. Excellent Free Cash Flow Margin Boosts Reinvestment Potential
Free cash flow isn't a prominently featured metric in company financials and earnings releases, but we think it's telling because it accounts for all operating and capital expenses, making it tough to manipulate. Cash is king.
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 31.6% over the last two years.

Final Judgment
These are just a few reasons why we think Duolingo is one of the best consumer internet companies out there, and with its shares beating the market recently, the stock trades at 54.2× forward EV-to-EBITDA (or $326.71 per share).
