A Stellar Quarter Overshadowed by Weak Guidance
Duolingo's Q4 2025 results told a tale of two narratives. Revenue surged 35% year-over-year to $282.9 million, topping analyst estimates of $275.9 million — a 2.5% beat. Adjusted EBITDA came in at $84.35 million, against Wall Street expectations of $78.24 million, representing a 7.8% outperformance with a 29.8% margin. Operating margin expanded to 15.4%, up sharply from 6.6% in the same period a year earlier.
Guidance Miss Triggers Selloff
The market's reaction was swift and severe. Shares fell more than 21% in after-hours trading following the earnings release, with the stock trading down to approximately $91.61 — marking one of its worst single-session performances in months.
The culprit: forward-looking guidance that landed significantly below Wall Street expectations. For Q1 2026, Duolingo projected bookings of approximately $301.5 million, well below analyst forecasts of $329.7 million. For the full year, the company guided bookings in the range of $1.27 billion to $1.30 billion, trailing the consensus estimate of $1.39 billion. Full-year revenue guidance of $1.20 billion to $1.22 billion also underwhelmed versus expectations of $1.26 billion.
Full-year EBITDA guidance of approximately $302 million fell far short of the Street's estimate of $385 million, as management outlined plans to invest heavily in AI-powered features and broader user access.A Strategic Bet on the "Size of the Pie"
CEO Luis von Ahn framed the guidance gap as a conscious and calculated trade-off. The company is deliberately prioritizing user growth over near-term monetization, a reversal from several years of fine-tuning subscription prompts and ad placements to boost bookings-per-user.
"Another way of seeing it is that long-term value in this business is driven by two things: the size of our active learner base — that's like the size of the pie — and how effectively we monetize that base," von Ahn explained. "At this moment, we are prioritizing growing the size of the pie."
Central to this shift is the company's AI-powered "Video Call with Lily" feature, which will be expanded from the premium Max tier to the broader Super Duolingo subscription, making it accessible to roughly ten times as many learners. The company noted that the cost to run the AI video call feature has dropped more than tenfold since launch, enabling broader rollout without proportional cost increases.
Bookings growth is now expected to come in around 11% for 2026, compared with the approximately 20% the company said it could have achieved under its previous, more monetization-focused strategy. Adjusted core profit margin is forecast to decline to roughly 25% this year as Duolingo accelerates AI investment and steps up marketing spend.Daily Active User Growth Slows
A central concern raised by management — and seized upon by analysts — was the deceleration in daily active user growth throughout 2025. The company now expects DAU growth of approximately 20% in 2026, roughly half the pace of prior years.
Von Ahn acknowledged the slowdown directly: "Some of this deceleration is natural as we scale, and some of it, we believe, is a function of our increased focus on monetization in recent years." The company is also expanding its content roadmap, investing in advanced courses across nine widely learned languages and developing subjects such as Chess, Math, and Music as future growth engines.
Analyst Reaction and Downgrades
The guidance miss triggered immediate analyst downgrades. Morgan Stanley cut its rating on Duolingo, citing persistent concerns around growth deceleration. The downgrade added further pressure on the stock, compounding the after-hours losses into the regular trading session.
Sell-side consensus now projects revenue growth of 21.4% over the next 12 months — a meaningful deceleration versus the company's three-year compounded annual growth rate of 41.1%.
Retail Traders Push Back
Not all market participants agreed with the selloff's severity. Retail sentiment on Stocktwits surged to "extremely bullish" from "bearish" territory compared to the prior session, with message volumes hitting "extremely high" levels. Some retail investors called the selloff "stupid," arguing that CEO von Ahn is executing a sound long-term strategy that will ultimately benefit shareholders. Others flagged the stock as "undervalued" following the sharp decline.
Market Outlook
Duolingo shares have now declined more than 62% over the past 12 months, and the stock sits sharply below its mid-2025 peak of over $540. The near-term trajectory will hinge on whether the company's growth-first strategy delivers measurable daily active user acceleration in 2026. With a $400 million buyback authorization as a potential support mechanism and AI-driven features expanding across the platform, the market will be watching closely for early evidence that the strategic reset is gaining traction.
