Unisound's stock plummeted 5.24% during intraday trading on Wednesday, reflecting a sharp pullback in the session.

This decline follows a significant surge of over 27% in the previous session, which was driven by the company's strong full-year financial results. Unisound reported total revenue of approximately RMB 1.211 billion, representing a 29% year-over-year increase, with revenue from its large-model-related business soaring more than tenfold to reach RMB 610 million.

Additionally, the company announced that four of its research papers were accepted at ACL, a top-tier international NLP conference, and it launched a new desktop AI Agent product called U2Claw targeting enterprise-level office applications. The current price drop is widely seen as a technical correction or profit-taking activity by investors after the substantial rally prompted by these positive developments.
