Duolingo Inc. (Duolingo (DUOL)) reported first-quarter results after Monday's closing bell, beating analyst estimates on both the top and bottom lines. But the market wasn't impressed — the stock dropped nearly 10% in extended trading after the company issued disappointing revenue guidance.

Here's a look at the details inside the report.

Duolingo Q1 Details

Duolingo reported quarterly earnings of 89 cents per share, beating the consensus estimate of 79 cents. Revenue came in at $291.97 million, above the Street estimate of $288.49 million.

User growth remained strong. Daily active users (DAUs) grew 21% year-over-year to 56.5 million, and paid subscribers also rose 21% to 12.5 million over the same period.

"In Q1, we made progress on the strategy we laid out last quarter," said Luis von Ahn, CEO of Duolingo. "We've made speaking a core part of the learning experience, and we've added more features and content to continue to support learners."

Outlook

Despite the solid quarter, Duolingo narrowed its fiscal 2026 revenue outlook to $1.205 billion, slightly below the $1.209 billion analyst estimate. That was enough to spook investors.

DUOL Stock Price: According to data from MarketDash, Duolingo stock was down 9.96% to $99.25 in Monday's extended trading.
