First loss in a decade as policy squeezes demand and prices Wondfo's 2025 revenue fell 31.91% and it posted its first loss since listing, hit by centralized procurement and DRG/DIP payment rules that cut test volumes and prices.

Buyback and controlling-shareholder purchases signal insider confidence The company approved a 30-60 million yuan buyback, and controlling shareholder Wang Jihua bought 1.156 million shares for about 20 million yuan, completing her 20-40 million yuan plan. Insiders putting real money in suggests they see the shares as undervalued, which can support the price.
