AstraZeneca's shares fell 8.4% on the London Stock Exchange amid concerns over a Chinese investigation into alleged aggressive sales tactics for its oncology drugs, Tagrisso and Imjudo. The company's local president, Leon Wang, is under investigation, signaling increased scrutiny from Beijing. Despite the turmoil, AstraZeneca aims for $80 billion in sales by 2030, up from $45.8 billion in 2023, with plans to launch 20 new drugs by the decade's end.
