WuXi AppTec has reported a 20.2% decline in net profit, amounting to CNY4.2 billion (USD584 million) for the first half of the year, alongside an 8.6% drop in revenue to CNY17.2 billion (USD2.4 billion). This downturn comes as the company faces challenges from a proposed U.S. bill aimed at severing ties with Chinese biotechnology firms. Despite these financial setbacks, WuXi AppTec's shares rose by 6% as of 9:40 a.m. on July 30, 2024, indicating a potential market reaction to the earnings report or broader investor sentiment.
