WH Group's stock price plummeted 5.01% during intraday trading on Tuesday, following a significant sell-off triggered by internal governance disputes.

The sharp decline was directly caused by a public article published by Wan Hongjian, the son of WH Group founder Wan Long, in which he accused the company patriarch of ten major wrongdoings including authoritarian management, problematic personnel decisions, tax avoidance, and interest transfer between entities. This public airing of family and governance issues has reignited investor fears over management stability and potential legal exposure related to historical equity restructuring.

This governance controversy comes despite a positive fundamental backdrop for the company, including recent analyst upgrades and strong first-quarter financial results. However, the escalating public dispute within the founding family has overshadowed these positive factors, leading to the significant intraday price movement.
