Hai Phong Thermal Power CEO Arrested in Environmental Scandal; Multiple Energy Firms Hit

Overview

Hai Phong Thermal Power (HND) announced the prosecution and detention of its CEO, Duong Son Ba, for document forgery as part of a broader environmental monitoring scandal. The case involves 74 defendants across 59 companies, including multiple power firms and state environmental management units. Similar leadership arrests have occurred at PECC1 (TV1), PC1 Group (PC1), and PECC2 (TV2), highlighting widespread governance issues in the sector.

• The case involves 74 defendants charged with 10 criminal counts, spanning 59 companies including thermal power plants, aluminum, steel, and environmental firms.
• Other arrested executives include TV1 Chairman Nguyen Huu Chinh (detained May 22), and unnamed leaders at PC1 and TV2.
• HND operates the 1,200 MW Hai Phong Thermal Power Plant, a key power source for northern Vietnam.
• HND’s major shareholders: EVNGENCO2 (51%) and Pha Lai Thermal Power (nearly 26%).

What Happened

On May 21, 2026, Hai Phong Thermal Power received a notice from the Ministry of Public Security’s Investigation Police Agency that its CEO and legal representative, Duong Son Ba, had been prosecuted and detained for investigation into “forging documents of agencies and organizations.” The arrest is part of a larger probe into environmental monitoring violations at multiple industrial facilities across Vietnam.

According to the Ministry of Public Security, the investigation has uncovered widespread manipulation of environmental data, where emissions and wastewater readings were altered to show compliance when actual levels exceeded permitted thresholds. The probe, led by the Environmental Crime Prevention Police Department (C05) in coordination with the Investigation Police Agency (C01), has implicated 59 companies and 74 individuals. Besides HND, other major power plants such as Quang Ninh Thermal Power and Thai Binh 2 Thermal Power are also under scrutiny.

Market Context

HND shares traded at VND 10,700 on May 24, near the bottom of its 52-week range, with extremely thin volume of just 3,400 shares, suggesting limited liquidity and potential investor caution. The stock has been under pressure since the environmental scandal emerged. In contrast, PC1 shares rose 1.48% to VND 20,600 on heavy volume of 12.9 million shares, possibly reflecting a decoupling from the legal issues. TV1 and TV2, both consulting firms, saw declines of 2.03% and 4.54% respectively, indicating negative sentiment toward companies directly implicated. All four tickers trade on HOSE.

Strategic Significance

The arrests signal heightened regulatory enforcement in Vietnam’s energy sector, particularly around environmental compliance and corporate governance. For HND, the detention of its CEO creates immediate operational uncertainty, though the company’s majority state ownership (EVNGENCO2) may provide stability. The broader probe could lead to fines, remediation costs, or even license revocations for affected plants. For investors, the incident underscores governance risks in state-linked enterprises and the potential for cascading legal liabilities across the supply chain, as seen with TV1, PC1, and TV2.

What to Watch

• Further arrests or charges against other executives at HND or related entities.
• Any operational disruptions at Hai Phong Thermal Power Plant, including potential shutdowns for environmental audits.
• Regulatory actions by the Ministry of Natural Resources and Environment, including fines or suspension of environmental permits.
• Q2 2026 earnings reports from HND, TV1, PC1, and TV2 for signs of financial impact.
• Share price reactions and trading volumes, especially for HND, as the market prices in legal risks.
