The public tender offer is the minority-protection mechanism of a public company: when an investor accumulates shares to a control level, every other shareholder must have the chance to sell out on the same public terms. The investor’s problem is that this duty switches on by ownership threshold, not by intent — crossing a threshold without a tender offer is a breach even for a wholly good-faith purchase. This article clarifies the tender-offer thresholds and procedure sequence in Vietnam.
The principle of the tender-offer mechanism is aggregation and transparency: the ownership ratio is computed on the investor together with related persons, and every threshold-touching purchase must go through the public procedure instead of quiet private trades. A share-accumulation roadmap for a public company must therefore be designed around these thresholds from the start. The locking file for this step is the projected ownership map step by step, checked against the statutory thresholds, plus the tender-offer registration file when a threshold is touched.
Legal basis in force for this topic (checked on 20 October 2026)
The foundation frame is the Law on Securities 54/2019/QH14 and Decree 155/2020/ND-CP: tender offers, disclosure, insider trading and minority rights in every transaction touching a public company must be reviewed before the transaction is announced or signed. Within the same frame, merging an unlisted company into a listed one — a reverse merger — is no shortcut around listing conditions: the post-merger enterprise must still meet listing, trading-registration and disclosure conditions under the law and the rules of the stock exchange.
The concrete tender-offer mechanism sits in Decree 155/2020/ND-CP: an organisation, an individual and their related persons whose purchase of voting shares reaches the statutory ownership thresholds — the first threshold commonly cited is 25% of total voting shares — must conduct a public tender offer, except in the exemption cases provided by that decree. It should also be known that current Vietnamese law has no direct squeeze-out mechanism for a large shareholder, so the tender offer is the main lawful path to gathering in a public company’s minority.
Each instrument above was checked for effectivity on the drafting date, 20 October 2026, for this tender-offer-threshold file specifically; a predecessor text, where mentioned, appears only in a transitional context with its replacement named. The exact thresholds and exemption cases must always be re-checked against the instrument in force at transaction time.
Analysis by practical question
At what percentage must a tender offer be made? The tender-offer duty arises when an investor together with related persons buys voting shares reaching the statutory ownership thresholds in Decree 155/2020/ND-CP: the first threshold commonly cited is 25% of total voting shares, and higher thresholds keep triggering the duty at subsequent ownership bands under the decree. The most important technical point is related-person aggregation: accumulating through several accounts or related entities does not change the duty. Exemption cases exist but are narrow and must be confirmed in advance, never assumed.
How long does a tender offer take? A tender offer runs a chain of steps with statutory timing: registration with the securities regulator, disclosure, the offer period for shareholders to tender, and payment — closing. Total real time is usually measured in many weeks to a few months depending on file complexity and regulator feedback, not counting prior preparation of the valuation file and financing arrangements. The investor must build this whole chain into the deal roadmap from the start, because every private purchase step during the tender-offer wait is tightly restricted.
What happens if we keep buying without a tender offer? Buying past a threshold without conducting a public tender offer breaches securities law: the transaction can draw administrative penalties under the securities sanctioning frame, an order to conduct a supplementary tender offer and remedy consequences, and the unlawfully acquired shares risk voting-right restrictions as regulated. Beyond sanctions, the largest cost is reputation and deal closability — a takeover tainted by a tender-offer breach is very hard to complete cleanly. The only prevention is to compute aggregated ownership before every purchase step and stop exactly at the threshold when not ready to launch the offer.
