CuriosityStream surged 18.62% in premarket trading following the release of its Q3 2025 earnings report, which highlighted a 46% year-over-year revenue increase to $18.4 million, driven by strong performance in content licensing (up over 400% YoY) and subscription services. Management guided for 40% revenue growth in 2025 and emphasized AI video training data licensing as a high-margin growth driver, with licensing revenue projected to surpass subscriptions by 2027. Despite a wider-than-expected loss of $0.06 per share, investors focused on the company’s 59% gross margin, $4.8 million adjusted free cash flow, and a robust launch pipeline. The CEO also noted disciplined cost management and a dividend yield exceeding 8%, reinforcing confidence in the company’s financial resilience and growth trajectory.
