China And Asia Expansion Will Transform Digital Education

Key Takeaways

• Expansion into new educational categories and international markets is broadening Duolingo's user base and strengthening long-term growth potential.
  
• Enhanced monetization strategies and AI-driven personalization are increasing user engagement, margins, and recurring revenue.
  
• Slowing user growth in core markets, regulatory barriers abroad, AI-driven competition, limited near-term benefits from new subjects, and user backlash all constrain future earnings potential.

Catalysts

Operates as a mobile learning platform in the United States, the United Kingdom, and internationally.

• Rapid adoption and engagement growth in emerging international markets (notably China and broader Asia), fueled by partnerships and the ongoing rise in demand for multilingual skills as global social and economic mobility increases, supports sustained expansion of Duolingo's total addressable market-positively impacting revenue and long-term earnings potential.
  
• Continued investment in and expansion of adjacent educational categories such as Math, Music, and Chess leverages Duolingo's gamification infrastructure and strong brand; these new subjects broaden the platform's appeal, attract additional user segments, and are expected to drive higher ARPU and incremental revenue streams over the next several years.
  
• The rollout of new monetization mechanics (e.g., the "Energy" system for free users) and improvements in subscription plan features (especially the Max tier with Video Call) are increasing user engagement, improving conversion rates from free to paid, and supporting ARPU and recurring revenue growth.
  
• Strategic investments in AI-driven personalized learning and model optimization are yielding reduced unit costs, improved gross margins, and enhanced scalability; as compute costs decline further, expanded access to higher-tier Max features in international markets is expected to support margin expansion.
  
• Early positive results from localized partnerships, marketing in under-penetrated regions, and price optimization experiments-plus the ongoing global shift toward digital, lifelong learning and recurring subscription models-position Duolingo for long-term secular revenue and net margin growth as digital education adoption accelerates worldwide.

Duolingo Future Earnings and Revenue Growth

Assumptions

• Analysts are assuming Duolingo's revenue will grow by 25.8% annually over the next 3 years.
• Analysts assume that profit margins will increase from 13.2% today to 20.8% in 3 years time.
• Analysts expect earnings to reach $367.0 million (and earnings per share of $6.45) by about August 2028, up from $117.2 million today.
• In order for the above numbers to justify the analysts price target, the company would need to trade at a PE ratio of 88.2x on those 2028 earnings, down from 128.2x today. This future PE is greater than the current PE for the US Consumer Services industry at 17.2x.
• Analysts expect the number of shares outstanding to grow by 5.24% per year for the next 3 years.
• To value all of this in today's terms, we will use a discount rate of 7.09%, as per the Simply Wall St company report.

Duolingo Future Earnings Per Share Growth

Risks

• Slowing growth in DAUs and MAUs in mature markets like the U.S., partly driven by reduced marketing spend and potential early signs of market saturation, could limit further significant revenue expansion in Duolingo's core regions.
  
• Increasing regulatory hurdles in key growth markets like China, where restrictions on using foreign AI models have delayed product rollouts (such as Max), may constrain the company's ability to monetize and optimize offerings, with direct impacts on earnings from these regions.
  
• Intensifying competition from both AI-powered language tools and specialized, integrated offerings from large tech firms (e.g., Google, Apple, OpenAI), combined with commoditization of language learning due to AI advancements, threatens Duolingo's pricing power and could exert downward pressure on net margins.
  
• Duolingo's expansion into new subjects (Math, Music, Chess) is highlighted as exciting but acknowledged by management as unlikely to provide meaningful incremental revenue in the near to medium term, which may limit drivers for sustained ARPU and earnings growth.
  
• Negative user sentiment and backlash around feature changes (such as the switch from Hearts to Energy), controversies related to AI/internal communication, or broader digital fatigue trends can undermine user engagement and potentially increase churn, putting both revenue and margins at risk.

Valuation

• The analysts have a consensus price target of $497.236 for Duolingo based on their expectations of its future earnings growth, profit margins and other risk factors. However, there is a degree of disagreement amongst analysts, with the most bullish reporting a price target of $600.0, and the most bearish reporting a price target of just $390.0.
  
• In order for you to agree with the analyst's consensus, you'd need to believe that by 2028, revenues will be $1.8 billion, earnings will come to $367.0 million, and it would be trading on a PE ratio of 88.2x, assuming you use a discount rate of 7.1%.
  
• Given the current share price of $327.93, the analyst price target of $497.24 is 34.0% higher.
  
• We always encourage you to reach your own conclusions though. So sense check these analyst numbers against your own assumptions and expectations based on your understanding of the business and what you believe is probable.
