Overview
The State Securities Commission (UBCKNN) fined Công ty TNHH Đầu tư – Xây dựng – Thương mại – Sản xuất CNC nearly VND 660 million for failing to report a planned transaction and for not registering a public tender offer when its related-party holding in CT3 reached 25.44%. The decision, issued under Quyết định số 642/QĐ-XPHC, forces CNC to sell down below the tender-offer threshold within six months, a potential overhang for the UPCOM-listed construction contractor.
Key Facts
- Total administrative fine: nearly VND 660 million, split into VND 435 million and VND 225 million penalties.
- VND 435 million equals 3.5% of the actual traded securities value at par, for failing to report a planned transaction.
- CNC bought 1,242,379 CT3 shares on 17/10/2025 without a planned-transaction disclosure.
- The purchase lifted CNC and related parties to 2,238,734 CT3 shares, or 25.44% of voting shares.
- VND 225 million penalty for not registering a public tender offer for that purchase.
- Additional sanction: a 3.5-month suspension of securities trading activity.
- CNC must divest below the mandatory tender-offer threshold within a maximum of six months from the decision’s effective date.
- CNC is a related organisation of ông Vương Tấn Hát, Chairman of CT3’s board.
What Happened
According to the State Securities Commission, CNC — an entity linked to Vương Tấn Hát, Chairman of the board of Công ty CP Đầu tư và Xây dựng Công trình 3 (ticker CT3) — purchased 1,242,379 CT3 shares on 17/10/2025. The regulator found that CNC did not file the required report on its planned transaction ahead of the purchase, triggering a fine of 3.5% of the traded value at par, or VND 435 million, plus a 3.5-month suspension from securities trading.
The same purchase pushed CNC’s combined holding with related parties to 2,238,734 CT3 shares, equal to 25.44% of voting shares as of 17/10/2025. Because that crossed the 25% threshold at which a public tender offer is mandatory, and no offer was registered, the commission imposed an additional VND 225 million fine. Beyond the cash penalties, the decision strips CNC of voting rights on the shares acquired through the violation and requires it to sell down to below the tender-offer threshold within six months of the measure taking effect. The filing does not disclose the market value of the divestment or the intended sale method.
Market Context
CT3 trades on UPCOM, Vietnam’s third-tier exchange for unlisted public companies, where liquidity is thin and disclosure gaps are more common than on HOSE or HNX. The stock closed at VND 5,500 on 25/10/2026, placing it in penny-stock territory where a 1.24 million-share block is large relative to typical daily turnover. The case fits a broader pattern of intensified UBCKNN enforcement on related-party transactions and tender-offer compliance, an agenda that has gathered pace as Vietnam pushes for FTSE Russell emerging-market reclassification.
Strategic Significance
The core issue is governance at a family-linked construction company: a chairman-associated entity accumulated a blocking-relevant stake without the market visibility that tender-offer rules are designed to provide. For long-term holders, the forced divestment introduces a known seller into an illiquid UPCOM order book, and the voting-rights suspension temporarily neutralises 25.44% of the register at shareholder meetings. The precedent matters more broadly: regulators are treating threshold breaches by related parties as strict-liability events, raising compliance costs for controlling-shareholder structures across small-cap construction names.
What to Watch
- CNC’s divestment disclosures on UPCOM, including timing, price and block-trade versus matched-order execution.
- CT3’s next shareholder meeting agenda and quorum, given the suspended voting rights on 25.44% of shares.
- Whether UBCKNN extends enforcement to other related-party holdings at CT3 or affiliated entities.
- CT3’s semi-annual financial statements for any commentary on ownership changes or governance remediation.
- Any appeal or administrative challenge by CNC against Quyết định số 642/QĐ-XPHC.
