Overview
Mr. Luu Bach Dat, CEO of Duc Giang Chemicals (DGC), has been appointed Chairman of the Board of Directors of Tia Sang Battery (TSB), replacing Mr. Dao Huu Huyen who was prosecuted by the Ministry of Public Security. The leadership change comes as TSB reported a net loss in Q1/2026 and was fined for tax violations. DGC holds a 51% stake in TSB.
Key Facts
- Mr. Luu Bach Dat, born 1983, is currently a Board member and CEO of Duc Giang Chemicals (DGC), which holds 51% of TSB.
- The appointment was effective from May 14, 2026, one day after Mr. Dat and Mr. Doan Van Quang were elected to TSB’s board at an extraordinary general meeting on May 13.
- Former Chairman Dao Huu Huyen and his son Dao Huu Duy Anh were removed from the board due to their prosecution by the Police Investigation Agency.
- TSB reported a net loss of VND 1.29 billion in Q1/2026, compared to a profit of VND 200 million in the same period last year.
- TSB was fined nearly VND 122 million by the Hai Phong tax authority in March 2026 for incorrect tax declarations, with additional tax arrears of VND 596 million.

What Happened
On May 14, 2026, the Board of Directors of Tia Sang Battery (Tibaco, HNX: TSB) approved the appointment of Mr. Luu Bach Dat as Chairman for the 2023-2028 term, replacing Mr. Dao Huu Huyen. Mr. Dat is currently a Board member and CEO of Duc Giang Chemicals (DGC), which owns 51% of TSB. The decision followed an extraordinary general meeting on May 13 where shareholders voted to remove Mr. Huyen and his son Mr. Dao Huu Duy Anh from the board due to their prosecution by the Ministry of Public Security for violations related to accounting, illegal resource exploitation, and environmental pollution.
Simultaneously, at Phosphorus Apatit Vietnam (PAT), another DGC-related company, an extraordinary meeting was held to restructure management, with Mr. Dat also elected to PAT’s board. These changes are part of a broader reshuffling across DGC’s ecosystem following the prosecution of several individuals.
Market Context
DGC closed at VND 48,800 on May 20, 2026, down 2.20% with high volume of 5.14 million shares. PAT closed at VND 68,200 (-1.30%) and TSB at VND 19,400 (+0.52%). DGC’s stock has been under pressure recently, with trading restrictions imposed on May 20 due to delayed audited financial statements. The leadership changes at TSB and PAT come amid legal and operational challenges, including TSB’s Q1 net loss and tax penalties.
Strategic Significance
DGC’s appointment of its CEO as Chairman of TSB reinforces its control over the battery subsidiary, which is a key downstream user of DGC’s phosphorus chemicals. The move aims to stabilize operations after the prosecution of former management. However, TSB’s weak financial performance—a net loss in Q1 and tax fines—highlights operational risks. DGC’s broader restructuring across its ecosystem (including PAT) suggests a concerted effort to address governance issues and comply with regulatory scrutiny. For investors, the key question is whether these changes will improve TSB’s profitability and restore confidence in DGC’s corporate governance.
What to Watch
- TSB’s Q2 2026 earnings release, expected in August, to see if cost controls and new management can reverse the loss.
- DGC’s audited 2025 financial statements, due in Q2 2026, which may clarify the impact of legal issues on its own books.
- Further developments in the prosecution of former TSB and PAT executives, which could lead to additional fines or asset seizures.
- TSB’s annual general meeting on or before June 30, where shareholders will vote on the new board and future strategy.
- DGC’s trading restriction status on HOSE, which may be lifted after the audited statements are filed.
