What Happened
On May 21, 2026, Hai Phong Thermal Power JSC received a notice from the Ministry of Public Security’s investigative police regarding the prosecution and temporary detention of CEO Duong Son Ba. The charge is “forging documents of state agencies.” The company’s board immediately resolved to transfer legal representation to Chairman Ta Cong Hoan, effective the same day.
The arrest is part of a large-scale investigation into environmental monitoring violations. According to the Environmental Crime Prevention Police Department (C05), 74 defendants from 59 companies have been prosecuted for tampering with emission monitoring data. The affected facilities include major thermal power plants such as Quang Ninh, Hai Phong, and Thai Binh 2, as well as aluminum, steel, and environmental treatment firms. Investigators found that monitoring data was manually altered or remotely manipulated before being transmitted to regulatory agencies.
Market Context
HND shares closed at 10,500 VND on the announcement day, down nearly 1% from the prior close of 10,700 VND on May 24, with thin volume of 3,400 shares. The stock trades on UPCoM and has been under pressure amid the ongoing environmental scandal. The broader energy sector on UPCoM has been relatively stable, but governance risks at HND may weigh on investor sentiment.
Strategic Significance
The detention of HND’s CEO highlights significant governance and compliance risks at the company, which is majority-owned by state-controlled Generation Company 2. The environmental monitoring scandal could lead to fines, operational disruptions, or reputational damage. For long-term investors, the incident underscores the importance of regulatory compliance in Vietnam’s power sector, especially as authorities intensify enforcement. The swift appointment of Chairman Ta Cong Hoan as legal representative suggests an effort to stabilize management, but further legal developments could impact operations.
What to Watch
- Outcome of the criminal investigation and any potential fines or penalties imposed on HND.
- Any changes in HND’s operational permits or environmental compliance status.
- Management stability and potential further leadership changes.
- HND’s Q2 2026 earnings report for signs of operational impact.
- Broader regulatory actions against other thermal power plants implicated in the scandal.
