Duolingo (DUOL) shares were down nearly 26% in recent premarket activity Friday after the company overnight provided a downbeat sales outlook.

The company reported Q4 net income late Thursday of $42 million, up from $13.9 million a year earlier.

Revenue for the three months ended Dec. 31 rose to $282.9 million from $209.6 million a year earlier.

Analysts polled by FactSet expected $276 million.

The company expects revenue of $288.5 million in Q1 and about $1.2 billion to $1.22 billion in 2026. Analysts polled by FactSet expect revenue of $291.4 million in Q1 and $1.26 billion in the full year.

"We expect bookings growth of around 11% in 2026, compared to the nearly 20% we believe we could achieve if we operated like we have in past years," the company said in a shareholder letter.

Duolingo said its board authorized a $400 million share repurchase program.
