The Appen share price is up 27% to $1.38. Investors have been buying the artificial intelligence data services company's shares following the release of a strong quarterly update. Appen reported revenue of $73.4 million. This was a 10% lift on the prior corresponding period and a 33% increase on the third quarter of FY 2025. Appen's CEO, Ryan Kolln, said: "Q4 was a strong finish to the year for both our China and Global businesses.
