Shares of Weigao Group (HKG:1066) plummeted 6.01% in the intraday trading session, reflecting investors' reaction to the company's disappointing first-half financial results released the previous evening.

The single-use medical device company reported a 9% decline in attributable profit for the first half of 2025, falling to 1.01 billion yuan from 1.11 billion yuan in the same period last year. This significant drop in profitability appears to be the primary driver behind the stock's sharp decline.

Despite maintaining a consistent revenue of 6.64 billion yuan year-over-year, Weigao Group's earnings per share decreased from 0.24 yuan to 0.22 yuan. The company has proposed an interim dividend of 0.0969 yuan per share for the period, which may provide some consolation to shareholders amidst the profit downturn. However, the market's negative reaction suggests that investors were expecting better performance from the medical polymer specialist.
