In an M&A deal, minority shareholders are often the weakest party at the negotiating table: they do not control the information flow, cannot decide the price, and sometimes only learn of the deal when everything is settled. FLAT LAW FIRM’s advisory experience shows most losses of minority investors do not come from being “deceived”, but from failing to prepare protective tools before the deal happens.
This article systematizes minority shareholders’ legal rights under the Law on Enterprises, along with practical protection mechanisms to include in shareholders’ agreements and M&A contracts. The content is general reference only and does not replace advice for specific files.
Quick Summary
| Topic | Rights and protection mechanisms for minority shareholders in M&A transactions in Vietnam |
|---|---|
| Main basis | Law on Enterprises 59/2020/QH14 (amended by Law 76/2025/QH15); Articles 115, 132, 151 |
| Thresholds to remember | Holding 05% of ordinary shares: deep inspection rights, convening the GMS, requesting the Board of Controllers’ inspection; 10%: right to nominate BOD and Board of Controllers members |
| Exit right | Request the company to repurchase shares when dissenting from resolutions on corporate reorganization or changes to shareholder rights and obligations (Article 132) |
Why minority shareholders are vulnerable in M&A
Three typical risks minority shareholders face in M&A deals:
First, information asymmetry. The buyer and controlling shareholders usually hold due diligence reports, valuations, and internal documents very early, while minority shareholders only receive information through General Meeting of Shareholders resolutions and meeting materials — often when core terms are already locked.
Second, dilution of ownership. M&A deals often come with additional share issuances for swaps or capital raising. Without anti-dilution mechanisms, minority shareholders’ ownership and voting rights can be significantly eroded after the deal.
Third, being forced to accept an unfair price. In full buyouts or mergers, minority shareholders may be compelled to transfer at a price set by the controlling party, absent an independent valuation mechanism.
That is why minority shareholder protection must be designed in two layers: the legal layer (minimum rights the law grants every shareholder) and the contractual layer (enhanced provisions investors negotiate themselves when contributing capital).
Core legal rights under the Law on Enterprises
The Law on Enterprises No. 59/2020/QH14 (amended and supplemented by Law No. 76/2025/QH15, effective from 01/7/2025) grants ordinary shareholders a fairly complete system of rights in Article 115. Most notable are the rights tied to ownership thresholds:
Shareholders or groups holding 05% or more of total ordinary shares (or a lower ratio if the company charter so provides) have the right to: examine, look up, and extract copies of Board of Directors minutes and resolutions, financial statements, Board of Controllers reports, and contracts and transactions subject to Board approval; request convening of the General Meeting of Shareholders when the Board of Directors seriously violates shareholder rights; request the Board of Controllers to inspect specific matters relating to the company’s management and administration.
Shareholders or groups holding 10% or more of total voting shares have the right to nominate members of the Board of Directors and the Board of Controllers — an important channel for minority shareholders to have a voice in governance.
In addition, Article 151 allows shareholders or groups holding 05% or more to request the Court or Arbitration to review and annul General Meeting of Shareholders resolutions if the meeting convening and decision-making procedures violate the law or the company charter, or the resolution’s content violates the law or the charter. This is an important legal “weapon” when an M&A resolution is passed opaquely.
Note: these thresholds are statutory minimums — the company charter may well set lower thresholds to strengthen minority shareholder protection. When reviewing a deal, the first thing a lawyer does is read the target’s charter carefully.
The right to request share repurchase — the exit when in disagreement
Article 132 of the Law on Enterprises provides a special “escape” mechanism: shareholders who voted against resolutions on corporate reorganization or changes to shareholder rights and obligations stipulated in the company charter have the right to request the company to repurchase their shares.
Conditions and procedure:
Request deadline: the request must be in writing, stating the shareholder’s name and address, the number of shares of each type, the intended selling price, and the reasons; it must be sent to the company within 10 days from the date the General Meeting of Shareholders passes the resolution. After this deadline, the repurchase right is lost.
Company’s obligation: the company must repurchase at market price or at a price calculated under principles in the company charter, within 90 days from receiving the request. If no price agreement is reached, the parties may request a valuation organization to appraise; the company nominates at least 03 valuation organizations for the shareholder to choose from, and that choice is final.
In the M&A context, this mechanism is especially meaningful when the deal is structured as a merger, consolidation, division, or split — cases within the scope of “corporate reorganization”. Dissenting minority shareholders can use this right to exit at market price instead of being swept along.
Note the limitation, however: this right only arises when the shareholder voted against — absent shareholders or abstainers can hardly invoke it. So when a reorganization resolution appears imminent, minority shareholders need to attend the meeting and clearly record their dissent in the minutes.
Protection mechanisms in shareholders’ agreements and M&A contracts
New point to attach to deals: beneficial owner obligations
From 01/7/2025, Law No. 76/2025/QH15 amending and supplementing the Law on Enterprises 2020 requires enterprises to collect, update, and keep beneficial owner information — individuals with actual ownership of capital or the ability to control the enterprise’s important decisions. In M&A transactions, the buyer needs to verify the seller’s actual ownership chain (especially where the seller is a multi-tier entity or has foreign elements), and put beneficial owner disclosure obligations into the contract’s conditions precedent and representations.
The contractual toolkit to have
Tag-along rights: when the major shareholder sells shares, minority shareholders may sell alongside on the same price terms — preventing being “left behind” with an unwanted new owner. Drag-along obligations: allowing the buyer to acquire 100% upon reaching the agreed threshold, in exchange for minority shareholders being guaranteed a minimum price. Anti-dilution: pre-emptive rights to new share issuances pro rata to current ownership. Veto rights on material matters: mergers, dissolution, business line changes, related-party transactions above thresholds — clearly listed in the charter and shareholders’ agreement. Read together with M&A Approval for Foreign Investors and Share Acquisition Checklist in Vietnamese Enterprises.
Statutory rights are only the minimum protection “floor”. Professional investors always negotiate additional mechanisms in the shareholders’ agreement (SHA) or directly in the M&A contract:
Veto rights on fundamental matters (reserved matters): listing decisions that cannot pass without minority shareholder consent — e.g., mergers, dissolution, changes to principal business lines, related-party transactions above thresholds, new share issuances. This is the strongest tool, but needs balancing so as not to paralyze company operations.
Pre-emptive rights and tag-along rights: when a major shareholder transfers shares to a third party, minority shareholders may tag along on the same terms — avoiding being “left behind” with an unwanted new owner.
Anti-dilution: mechanisms adjusting the conversion ratio or additional purchase rights when the company issues new shares below the price the minority investor paid.
Information transparency: commitments to provide periodic financial reports, the right to appoint an observer to Board of Directors meetings (without voting rights), and access to due diligence reports in M&A transactions.
Exit valuation mechanism: agreeing in advance on a price formula or process (e.g., the average of two independent valuation organizations) to avoid disputes when one party wants out.
Practical experience: protective provisions only work when drafted tightly and enforceably. An overly broad veto may be circumvented by the controlling party through roundabout deal structures; lawyers must anticipate workarounds when drafting.
Checklist for minority investors before entering a deal
Before investing as a minority shareholder, investors should complete these steps:
1. Review the company charter and existing shareholders’ agreement. Identify actual rights thresholds (which may be lower than statute), matters requiring special majorities, and existing transfer restrictions.
2. Assess the ownership structure and the ability to form a 5%/10% group. Holding 3% alone is weak, but allying with two other investors to cross the 5% threshold unlocks the full inspection and supervision rights.
3. Negotiate protective provisions into the SHA before contributing capital. The only moment a minority investor has negotiating leverage is before money goes in. After contribution, every SHA amendment needs the controlling party’s consent.
4. Prepare an exit plan. Agree in advance on events triggering sale rights (e.g., no IPO after X years, breach of undertakings) and the valuation mechanism.
5. Closely track reorganization resolutions. Remember Article 132’s 10-day deadline — this is a right with a very short prescription.

Frequently asked questions
What rights does a 3% shareholder have when the company does M&A?
A 3% shareholder retains full basic rights of an ordinary shareholder: voting rights, dividends, pre-emptive rights to new share issuances, free transfer, and inspecting the charter and GMS resolutions. However, enhanced rights (deep inspection of governance documents, requesting meetings, requesting resolution annulment) need the 5% threshold — a 3% shareholder should ally with others to cross it.
Can the company charter lower the 5% threshold further?
Yes. The Law on Enterprises allows the charter to set “another smaller ratio” than the 5% and 10% thresholds. This is a point minority investors should negotiate when contributing capital.
What if the 10-day repurchase request deadline is missed?
After Article 132’s 10-day deadline, shareholders may consider other avenues: requesting resolution annulment under Article 151 (with procedural or substantive grounds), transferring shares to a third party, or suing for damages for violations. Each avenue needs specific evidence assessment.
Are existing shareholders’ pre-emptive rights a statutory default?
Not entirely. The law only provides pre-emptive rights to newly issued shares (Article 115). Pre-emptive rights when another shareholder transfers existing shares are not default — they must be agreed in the charter or shareholders’ agreement.
Where are shareholder disputes resolved?
As agreed: they may be sued in Court or resolved by commercial arbitration if the parties have an arbitration agreement. With foreign elements, arbitration is often preferred for confidentiality and cross-border enforceability.
Does FLAT LAW FIRM support in Chinese and English?
Yes. We support communication, document review, and negotiation in Vietnamese, Chinese, and English.
