Shares of Prinx Chengshan (HKG:1809) plummeted 5.08% in intraday trading on Tuesday, following the release of the company's disappointing first-half 2025 financial results. The tire manufacturer reported a significant drop in profits, despite an increase in revenue.

According to a Hong Kong bourse filing on Tuesday, Prinx Chengshan's attributable profit for the first half of 2025 fell to 507.6 million yuan, down from 811.4 million yuan in the same period last year, representing a 37.4% decrease. Earnings per share also declined to 0.80 yuan from 1.27 yuan in the prior year.

Despite the profit decline, the company managed to grow its revenue by 6.4% year-on-year, reaching 5.71 billion yuan. However, this revenue growth was not enough to offset the impact of the reduced profitability on investor sentiment, leading to the sharp decline in the company's stock price.
