Duolingo Earnings Call: AI Bets, Growth And Margins

Duolingo, Inc. Class A ((DUOL)) has held its Q1 earnings call. Read on for the main highlights of the call.

Duolingo’s latest earnings call struck an upbeat tone, pairing strong user growth and solid profitability with a clear, AI-heavy investment roadmap. Executives framed 2026 as a pivotal build-out year, stressing that current margin pressure and softer near-term bookings are deliberate trade-offs to deepen the product, expand content, and sustain roughly 20% daily user growth for years.

Daily Usage Grows, Retention Strengthens

Daily active users climbed 21% year over year, underscoring the durability of Duolingo’s engagement engine. Management expects DAU growth to hover near 20% through 2026, driven less by sheer user acquisition and more by rising retention, as indicated by an improving DAU-to-MAU ratio.

Bookings, Revenue Keep Climbing

The company delivered double-digit growth in both bookings and revenue in the first quarter, and set explicit 2026 point estimates of about 10.5% bookings growth and 16.1% revenue growth. Those figures sit comfortably within reiterated target ranges of 10%–12% for bookings and 15%–18% for revenue, signaling confidence despite a tougher near-term comp setup.

Profitability Remains Robust, Cash Pile Grows

Adjusted EBITDA hit $83 million in Q1, roughly 29% of revenue, highlighting a rare blend of growth and profitability in consumer tech. With more than $1 billion in cash, no debt, expected free cash flow above $350 million this year and a $400 million buyback already retiring about 1% of diluted shares, Duolingo has ample firepower for both investment and shareholder returns.

AI Supercharges Content Scale

Duolingo published 20.5 thousand course units in the quarter, more than ten times its quarterly pace from two years ago, and now reaches B2, or professional-level proficiency, in its nine most popular languages. Management credited AI for unlocking this unprecedented content velocity and for enabling more personalized learning paths through smarter exercise selection.

Richer Teaching Features Deepen Engagement

The teaching experience is being upgraded with speaking-focused tools such as spoken tokens, speaking adventures, and flashcards, extending to both free and paid users. Video call practice is a standout, with the average words spoken per user more than doubling over the past year, suggesting deeper learning and a feature that could underpin future pricing power.

Margins High, But AI Will Nudge Them Lower

Gross margin expanded in Q1 and beat expectations even as AI content usage climbed, showing early efficiency in the new tech stack. Management, however, guided to a near-term step down, with gross margins around 71% in Q2 drifting toward 69% by year-end as more users tap into compute-intensive AI features.

2026 Marked as a Strategic Investment Year

Executives emphasized that 2026 is designed as an investment year, not a peak margin year, with point estimates of 10.5% bookings growth, 16.1% revenue growth, and a roughly 25.7% adjusted EBITDA margin. They laid out a detailed cadence with Q2 bookings near 6%, revenue around 17%, and an adjusted EBITDA margin of about 24%, followed by a back-half acceleration.

Monetization Tweaks Aim to Preserve Growth

Duolingo is testing ways to boost bookings without hurting engagement, including longer free trials such as one-month offers that have lifted conversions while remaining user-friendly. The company is also experimenting with where and how it charges for video call access across Super and Max tiers, with early data suggesting customers are willing to pay more for premium speaking experiences.

Flat MAUs Put Spotlight on Retention

Top-of-funnel metrics and monthly active users were roughly flat in the quarter, a slowdown from earlier expansion that shifts the growth burden onto engagement and word-of-mouth. Management leaned into this challenge, arguing that stronger retention and more compelling features can sustain DAU momentum even if the overall audience grows more slowly.

Tough Q2 Comp Creates Bookings Air Pocket

Q2 bookings are expected to grow only about 6%, reflecting a difficult comparison against last year’s rollout of the Energy system, a key price increase, and unusually strong advertising. The company framed this as a timing issue rather than a demand problem, with growth expected to reaccelerate in the second half once those one-off effects roll off.

AI Costs Weigh on Margins, But Are Managed

The expansion of AI-powered features brings rising costs, both in cost of revenue and in operating expenses, as Duolingo invests in models, infrastructure, and engineering. Guidance already bakes in these pressures, and management argued that the long-term payoff of AI-driven personalization and content scale justifies the modest dip in gross margin from low-70s toward the high-60s.

Geographic Mix Shifts Toward High-Growth Asia

While daily users are still growing in the U.S., the pace lags behind many international markets, with Asia, particularly China, emerging as the fastest-growing region. This shift in geographic mix could influence monetization patterns and bookings per user, as Duolingo fine-tunes pricing and product in markets with different income levels and regulatory dynamics.

Balancing Monetization After Past Missteps

Management candidly described a paradox of being historically over-monetized, with some paywalls hurting DAUs, yet still under-monetized, with only about 12% of monthly users paying. The current strategy focuses on reducing friction through friendlier offers like longer trials, even if that delays bookings recognition as users take more time to convert.

Performance Marketing Still a Work in Progress

The company acknowledged that performance marketing is underdeveloped and remains a key build-out area, especially outside proven markets like China where profitable acquisition is already possible. Developing attribution systems and marketing infrastructure is seen as a prerequisite to scaling spend, suggesting a future lever for growth once the engine is fully tuned.

Short-Term Margin Volatility Ahead

Investors should expect some chop in profitability, with Q3 adjusted EBITDA margin projected to be flat to slightly below Q2 levels before climbing toward roughly 27% in Q4. This near-term volatility reflects overlapping effects from AI adoption, product experiments, and pricing tests, all of which are intended to support stronger, more durable earnings power beyond 2026.

Forward-Looking Guidance Points to Stable Growth

Looking ahead to 2026, Duolingo reiterated its targets of 10%–12% bookings growth, 15%–18% revenue growth, and an adjusted EBITDA margin around 25%, supported by a cash-rich balance sheet and significant free cash flow. Near-term guidance calls for Q2 revenue growth of about 17%, Q2 gross margin around 71% trending to 69% by year-end, and a step-up in adjusted EBITDA margin to roughly 27% by Q4 as bookings growth accelerates.

Duolingo’s earnings call painted the picture of a company trading some short-term smoothness for long-term strategic advantage, with AI at the center of its product and cost story. For investors, the message was clear: expect volatility in margins and bookings over the next few quarters, but within a framework that still targets healthy growth, strong cash generation, and expanding competitive moats.
