Vidipha (VDP) Fined VND 812.5M for Tax Errors as Founders Exit

Overview

Vidipha (ticker VDP, listed on the Ho Chi Minh Stock Exchange) disclosed a Ho Chi Minh City tax authority decision dated 9 September 2026 requiring the company to pay VND 812.5 million in back taxes, penalties and late-payment interest for incorrect tax declaration. The pharmaceutical maker also reported a near-complete turnover of its shareholder base in August, with the chairman and other insiders exiting while new large shareholders accumulated stakes.

Key Facts

• Total payable: VND 812.5 million, comprising VND 108.7 million in penalties, VND 543.9 million in back corporate income tax (thuế TNDN) and VND 159.8 million in late-payment interest.
• The penalty stems from incorrect tax declaration that understated corporate income tax owed, per Decision No. 6454/QĐ-XPHC issued by Ho Chi Minh City tax authorities on 9 September 2026.
• Chairman Kiều Hữu sold his entire 1.65 million VDP shares (7.5% of capital) between 5 and 20 August 2026, at an average price of VND 36,908 per share, worth roughly VND 61 billion.
• His daughter Kiều Thúy Mai sold all 1.37 million shares (6.23% of capital), worth about VND 51 billion; together the two disposed of more than 3 million shares, or 13.7% of capital.
• New shareholder Lê Quang Hải bought more than 4.95 million VDP shares on 7 August 2026, lifting his holding from 0.087% to 22.5% of capital.
• Nguyễn Quốc Hùng bought over 2.5 million shares on 12 August 2026 via negotiated deal worth nearly VND 101.5 billion, then added 1.75 million shares on 25 August to reach 13.43%.
• Nguyễn Thị Yến acquired 3.82 million VDP shares on 25 August 2026, raising her stake from zero to 11.95% of capital.

What Happened

Vidipha announced receipt of an administrative penalty decision from Ho Chi Minh City tax authorities. The company must remit VND 812.5 million in total, split between a VND 108.7 million fine for incorrect declaration that led to underpaid corporate income tax, VND 543.9 million in recovered tax, and VND 159.8 million in late-payment interest. The disclosure did not specify which fiscal year or years the understatement relates to.

Separately, August filings show a broad reshuffling of the register. Chairman Kiều Hữu and his daughter Kiều Thúy Mai sold their entire holdings, as did board member Trần Văn Đạt and his wife Nguyễn Thị Ánh Thủy, and Đinh Thị Hoàng Oanh, wife of board member Phạm Tuấn Kiệt. On the buy side, Lê Quang Hải, Nguyễn Quốc Hùng and Nguyễn Thị Yến each crossed the large-shareholder threshold, with several transactions executed via negotiated deals.

Market Context

VDP closed at VND 26,600 on 10 September 2026, well below the roughly VND 36,908 average price at which the chairman sold in August, implying the shares have weakened since the insider exits. The stock trades on HOSE within the health care sector, where valuations have been sensitive to earnings quality and governance signals. The combination of a tax penalty and a wholesale ownership change places VDP outside the mainstream of Vietnamese pharmaceutical names, most of which have seen stable domestic demand but limited re-rating.

Strategic Significance

The tax ruling is small in absolute terms — roughly USD 32,500 — but it speaks to internal accounting controls at a company whose entire board-level ownership group has just departed. For long-term investors, the central question is whether the incoming shareholders, led by Lê Quang Hải at 22.5% and Nguyễn Quốc Hùng at 13.43%, intend to reshape strategy, capital allocation or governance, or are positioning for a specific corporate event. The absence of any disclosed strategic rationale in the filings leaves the thesis unresolved.

What to Watch

• Any Vidipha disclosure clarifying which fiscal year the understated corporate income tax relates to, and whether further periods are under review.
• Regulatory filings from Lê Quang Hải, Nguyễn Quốc Hùng or Nguyễn Thị Yến indicating intent, board representation or further accumulation.
• The next annual general meeting agenda, including any board restructuring following the chairman’s exit.
• Q3 2026 earnings release for evidence on margins and whether the tax adjustment affects reported profit.
• Trading volume and price behaviour around the VND 26,600 level relative to the August negotiated-deal prices.
