On May 22, 2026, Hai Phong Thermal Power Joint Stock Company (HOSE: HND) disclosed that its CEO, Duong Son Ba, was prosecuted and detained for allegedly forging documents. The case is linked to a broader environmental monitoring scandal involving multiple thermal power plants, including Quang Ninh Thermal Power (UPCoM: QTP). The arrests raise governance concerns for both companies.

What Happened
On May 22, 2026, Hai Phong Thermal Power Joint Stock Company (HND) issued an extraordinary disclosure to the State Securities Commission and Hanoi Stock Exchange. The company stated that on May 21, 2026, it received a document from the Police Investigation Agency of the Ministry of Public Security regarding the prosecution and temporary detention of Duong Son Ba, the company’s CEO and legal representative, for allegedly forging documents.
The investigation is part of a broader probe into environmental monitoring violations at numerous thermal power plants and other industrial facilities across Vietnam. According to initial findings, data from monitoring stations at plants including HND, QTP, and Thai Binh 2 were allegedly tampered with to show emissions within permitted limits when they were not. The scandal has already led to the arrest of QTP’s Deputy CEO Le Viet Cuong and two other QTP employees.
Market Context
HND shares closed at VND 10,700 on May 24, 2026, up 0.94% but with very low volume of only 3,400 shares, suggesting limited market reaction. QTP shares closed at VND 12,100, up 0.83% with higher volume of 366,100 shares. Both stocks trade on HOSE and UPCoM respectively. The energy sector has been under regulatory scrutiny, and this scandal adds to governance risks for thermal power companies.
Strategic Significance
The arrests signal heightened enforcement of environmental regulations by Vietnamese authorities, which could lead to increased compliance costs and operational disruptions for thermal power plants. For HND and QTP, the legal proceedings may distract management and potentially affect plant operations or permit renewals. Investors should assess the companies’ governance structures and environmental compliance track records. The scandal also highlights risks in the broader power generation sector, particularly for coal-fired plants.
What to Watch
- Further arrests or charges at HND or QTP as the investigation expands.
- Any operational disruptions or production halts at HND or QTP due to regulatory actions.
- Q2 2026 earnings reports for HND and QTP, which may reflect financial impacts.
- Updates on the environmental monitoring data tampering case from the Ministry of Public Security.
- Potential changes in management or board composition at HND and QTP.
