Duolingo, Inc. ($DUOL) reported its fourth-quarter earnings for 2024, revealing a revenue of $209.6 million, which represents a 39% year-over-year increase and surpasses analyst estimates of $205.85 million. The company also noted a substantial rise in daily active users (DAUs), reaching 40.5 million, up 51% from the previous year, and a growth in paid subscribers to 9.5 million, reflecting a 43% increase year-over-year. Adjusted earnings before interest, taxes, depreciation, and amortization (EBITDA) were reported at $52.3 million, exceeding estimates of $51.04 million. Despite these positive metrics, Duolingo's stock faced pressure, declining by 9% in pre-market trading, attributed to concerns over margin pressures linked to rising artificial intelligence costs. Analysts have mixed views on the outlook; while some maintain a bullish stance, raising price targets to as high as $430, others express caution about potential multiple compression in the stock price. The company’s guidance for the first quarter of 2025 anticipates revenue of $222 million, slightly above estimates, while full-year revenue is projected to exceed $1 billion.
