Sou Hu Cai Jing·2026-03-18 10:19Group 1 - The core issue revolves around two shareholders, who are heirs of a prominent private enterprise, announcing a reduction in their holdings, which led to a significant drop in the stock price of the leading CRO company, Zhaoyan Pharmaceutical, hitting the daily limit down [1] - Following the announcement, the company quickly revised its plan to reduce the total shareholding from 4.1% to no more than 3%, primarily through block trades, which helped stabilize the stock price [1] - Historically, the term "reduction" has negatively impacted Zhaoyan's stock price, with previous instances of share reductions leading to immediate declines of 5.7%, 7%, and 6% in stock price [1] Group 2 - Since the second half of last year, a total of nine shareholders have exited their positions, raising questions about the timing and reasons behind this trend, with speculation that it reflects a lack of confidence in the company's future [2] - Zhaoyan's stock price surged over 110% in 2025, climbing from around 20 yuan to 46 yuan, significantly outperforming other companies in the CRO sector [2] - The company has benefited from a surge in demand for experimental monkeys, with prices rising sharply, contributing to inflated profits that are not necessarily tied to operational performance, as the main business revenue has been declining for two consecutive years [2] - By early this year, Zhaoyan's price-to-earnings ratio reached 97, significantly higher than the 20-30 range of industry peers, raising concerns about the sustainability of this inflated valuation [2]
