What Happened
An Quy Hung Holding, a newly formed real estate advisory and brokerage firm, has become a major shareholder in Viwaseen (VIW) after acquiring 13.3 million shares on May 28, 2026. The purchase was executed via a block trade, as confirmed by HNX transaction data. The company is controlled by Nguyen Xuan Dong, who was recently appointed Chairman of Vinaconex (VCG), a major construction and export-import conglomerate listed on HOSE.
In a parallel move, Vinaconex has been reducing its stake in Viwaseen. Between April 23 and May 22, 2026, it sold nearly 6.7 million VIW shares, lowering its ownership to 86.01%. The company cited unfavorable market conditions for not completing the full planned sale. Immediately after, Vinaconex registered to sell an additional 35.4 million shares, aiming to reduce its stake to 25% by June 26, 2026. This divestment comes just months after Vinaconex acquired a controlling 98.16% stake from SCIC in late 2025.
Market Context
VIW shares on HNX closed at VND 22,900 on June 2, 2026, down 1.29% with thin volume of 194,800 shares. The stock has been under pressure amid the ownership changes. VCG, listed on HOSE, closed at VND 19,750, down 2.23% on volume of 5.08 million shares. The broader market has seen mixed sentiment, with real estate and construction sectors facing headwinds from rising interest rates and regulatory changes. The divestment by Vinaconex may reflect a strategic pivot away from environmental services, while the entry of An Quy Hung Holding introduces a new controlling shareholder with real estate expertise.
Strategic Significance
The entry of An Quy Hung Holding, linked to Vinaconex’s chairman, suggests a potential restructuring of Viwaseen’s business model toward real estate and land services, aligning with the holding company’s core competencies. Vinaconex’s rapid divestment, after acquiring control only months earlier, indicates a shift in capital allocation priorities, possibly to reduce debt or focus on core construction activities. For VIW, the change in control could lead to asset revaluation or new strategic directions, but the lack of disclosed plans creates uncertainty. The transaction also highlights the active M&A environment among Vietnamese state-owned enterprises and their affiliates.
What to Watch
- Completion of Vinaconex’s planned sale of 35.4 million VIW shares by June 26, 2026, and the resulting ownership level.
- Any public disclosure of An Quy Hung Holding’s strategic plans for Viwaseen, including potential asset injections or business redirection.
- VIW’s share price and trading volume on HNX, particularly around the divestment deadline.
- Vinaconex’s Q2 2026 earnings report for commentary on divestment proceeds and use of funds.
- Regulatory filings regarding any change in Viwaseen’s board composition or management following the stake change.
