Acquiring 51%, 65%, 75% or 100% of a Vietnamese company can produce very different levels of voting control, economic ownership, minority protection, consolidation, and exit flexibility. The percentage alone does not determine control: the company type, charter, shareholder agreements, reserved matters, quorum rules, and foreign-investment restrictions must also be reviewed.
Understanding these thresholds before signing term sheets is essential: acquiring a Vietnamese company at the wrong ownership level can leave a buyer without effective control even after closing.
This practical guide helps strategic buyers, private equity funds, foreign investors, founders, and boards compare common ownership levels before negotiating a Vietnam M&A transaction.

Why the same percentage can produce different control
A Vietnamese joint stock company and a limited liability company use different governance structures. Statutory voting rules may also be modified within permitted limits by the charter. Investor agreements can add veto rights, nomination rights, transfer restrictions, and quorum protections. Buyers should therefore model decisions rather than rely on a headline percentage.
Acquiring 51%: majority ownership with important limits
A 51% investor usually has economic majority and may control ordinary decisions where the applicable threshold is more than half of votes represented or entitled to vote. It may also support accounting consolidation, subject to the relevant accounting framework.
However, 51% may not be enough for decisions requiring a higher statutory or charter threshold. A minority investor may block amendments, reorganizations, major asset disposals, new securities, or other reserved matters. Quorum provisions can also reduce practical control if minority attendance is required.
When 51% may work
- The seller remains an active operating partner.
- The buyer wants consolidation but values founder continuity.
- Reserved matters are narrowly defined.
- There is a clear route to acquire the remaining interest.
Acquiring 65%: stronger control over major decisions
A 65% stake may align with important decision thresholds under Vietnamese enterprise rules, particularly in certain joint stock company voting contexts. It can materially reduce minority blocking power, but it is not automatically sufficient for every company or decision.
The charter may require a higher threshold, and an investor agreement may grant specific vetoes to minority owners. Buyers should examine the exact denominator, whether the test refers to attending votes or total voting capital, and whether related-party or conflicted votes are excluded.

Acquiring 75%: broad control with residual minority risk
A 75% position can provide broad power in structures where special decisions require that level and can protect a buyer acquiring a Vietnamese company against a 25% blocking stake. It may be commercially useful where the seller keeps meaningful upside but a buyer acquiring a Vietnamese company needs authority to restructure and integrate the target.
Residual minority rights still matter. The seller may retain information, dividend, pre-emption, transfer, tag-along, board, and statutory protection rights. Certain transactions may require fairness procedures, independent approvals, or compliance with the charter regardless of ownership.
Acquiring 100%: full ownership, not zero risk
Full ownership eliminates shareholder-level minority disputes and gives maximum flexibility over governance, dividends, financing, integration, and exit. It can simplify future restructuring and remove the need for drag-along or call-option mechanics.
Nevertheless, a buyer acquiring a Vietnamese company assumes complete economic exposure to the target. Historical tax, regulatory, employment, environmental, contract, land, and compliance risks remain within the company. Strong diligence, warranties, indemnities, escrow, and post-closing remediation may therefore be more important, not less.
Key comparison factors
Governance
Map appointment and removal of legal representatives, board members, directors, controllers, and committee members. Define who controls bank accounts, budgets, business plans, hiring, financing, and related-party transactions.
Reserved matters
List decisions requiring supermajority or minority consent. Avoid a veto list so broad that majority control becomes operationally ineffective.
Dividend and funding policy
Agree when profits are distributed, how new capital is funded, consequences of failure to contribute, and whether shareholder loans are permitted.

Transfer and exit
Coordinate lock-ups, rights of first refusal, pre-emption, tag-along, drag-along, call and put options, deadlock, valuation, and permitted transfers. A staged path from 51% to 100% should have objective pricing and completion mechanics.
Foreign-investment approvals
Foreign buyers must review market-access conditions, foreign ownership limits, sector licenses, land-related issues, investment registration, and any required pre-closing approval for acquiring shares or capital contributions. Competition clearance may also apply depending on statutory thresholds.
When acquiring a Vietnamese company in a conditional business line, crossing 51% or later increasing to 65%, 75%, or 100% can each independently trigger a fresh M&A registration or Investment Registration Certificate amendment, because Vietnamese authorities assess foreign ownership ratio changes at the point they occur, not only at the first closing. A buyer acquiring a Vietnamese company in stages should therefore confirm with counsel, before signing, which specific ownership thresholds in its sector require prior approval versus post-completion notification, since the answer varies by business line under Vietnam’s WTO commitments and sector-specific negative lists.
Practical control matrix
- 51%: potential ordinary-decision majority, with exposure to supermajority vetoes.
- 65%: stronger control over many important decisions, subject to charter and agreement.
- 75%: broad governance control in many structures, while minority rights continue.
- 100%: complete ownership and integration flexibility, with full economic risk.
Financing terms also shift with ownership level. Lenders financing a buyer acquiring a Vietnamese company below 65% often require additional minority-protection carve-outs in the loan documentation, since a buyer acquiring a Vietnamese company cannot unilaterally amend the charter or approve related-party transactions without the minority shareholder’s consent. Above 75%, most lenders treat the acquired company as fully consolidated for covenant and reporting purposes, which can materially ease the financing terms available for acquiring a Vietnamese company at that ownership level.
Due diligence questions before selecting a percentage
- What company type and voting rules apply?
- Which decisions use statutory, charter, or contractual thresholds?
- Can minority owners prevent quorum?
- Which licenses or approvals are affected by the ownership change?
- How will the remaining stake be valued and transferred?
- What happens if shareholders deadlock?
Sellers negotiating with a buyer acquiring a Vietnamese company should also plan for the tax consequences that differ by stake sold. A share transfer below 100% still triggers capital gains tax on the shares actually sold, calculated on the difference between transfer price and the seller’s original cost basis, while a full 100% exit can allow the seller to close out warranty and indemnity exposure entirely at completion rather than carrying residual minority-related risk. Structuring the price mechanism around the specific percentage being sold, rather than a flat headline number, is one of the most common negotiation gaps in deals for acquiring a Vietnamese company gradually.
Common negotiation pitfalls when acquiring a Vietnamese company
The most frequent mistake is negotiating the headline percentage before the governance mechanics. Buyers fix on 51%, 65%, 75% or 100% early in discussions, then discover during legal due diligence that the target’s charter sets supermajority thresholds far above the statutory minimum.
Sellers can use this gap to preserve blocking rights that a buyer acquiring a Vietnamese company believed it had priced out.
A second pitfall is treating reserved-matter lists as boilerplate. Vague or duplicated reserved-matter clauses between the charter and a shareholders’ agreement create interpretive disputes after closing, precisely when relations between buyer and remaining minority shareholders are most sensitive.
Drafting these lists with the actual post-closing ownership split in mind, rather than copying a template, avoids most of this friction.
A third pitfall is underestimating the time and documentary burden of foreign-investment approvals at higher ownership levels. Buyers who assume 65% and 100% deals close on the same timeline frequently miss conditions precedent deadlines, which can trigger break-fee exposure or force an unfavourable bridge arrangement with the seller.
How Vietnamese buyers and sellers approach ownership negotiations in practice
In practice, Vietnamese sellers of family-founded companies tend to resist 100% sales in the first conversation, even when they are commercially open to it, because retained equity signals continuity to employees, customers, and local authorities.
Buyers who lead with a staged structure — for example 51% at signing with a pre-agreed path to 100% — often reach agreement faster than buyers who insist on full ownership from day one.
Domestic private equity and strategic buyers acquiring a Vietnamese company frequently accept a slightly lower initial percentage in exchange for stronger contractual governance rights: a board seat, veto rights over budget and related-party transactions, and information rights. This trade-off can deliver more practical control than a marginally higher ownership percentage without such protections.
A worked example: moving from 51% to 100%
Consider a hypothetical illustration only. A foreign strategic buyer agrees to acquire 51% of a Vietnamese manufacturing company at closing, with a call option to acquire the remaining 49% over three years at a formula price tied to audited EBITDA.
The shareholders’ agreement grants the buyer board control and veto rights over capital expenditure above a threshold, while the founder retains day-to-day management for an agreed transition period.
This structure lets the buyer consolidate the target for accounting purposes from year one, while giving the founder an incentive to keep performance strong through the option period. The key risk to manage is the valuation formula: ambiguous EBITDA adjustment mechanics are the single most common source of post-closing disputes in staged Vietnam acquisitions.
Typical Vietnam market terms for staged ownership deals
Market practice in Vietnam for staged transactions commonly includes an initial tranche between 51% and 70%, a call/put option structure rather than a fixed forward obligation, and an independent-expert valuation mechanism for any subsequent tranche where the parties cannot agree on price.
Escrow of 10–15% of the initial purchase price for 12–18 months to cover warranty claims is also common.
Buyers acquiring a Vietnamese company through a staged structure should also confirm, before signing, how each tranche interacts with foreign-ownership caps in conditional sectors, since a later tranche that pushes foreign ownership past a sectoral limit may require a fresh investment registration procedure rather than a simple share transfer.
Frequently asked questions
Does 51% always give control in Vietnam?
No. It may provide majority ownership but not authority over decisions requiring higher thresholds or minority consent.
Is 65% always better than 51%?
Not necessarily. The extra stake must be evaluated against price, governance benefit, regulatory impact, and the seller’s continuing role.
Should a buyer acquire 100% immediately?
Only where full ownership benefits outweigh price, financing, integration, and risk considerations. A staged acquisition may sometimes better align incentives.
What is the minimum percentage for acquiring a Vietnamese company with effective control?
There is no single statutory minimum that guarantees control. In most joint stock companies, 65% is needed to pass many important resolutions, while 75% or more is typically required for the most significant charter amendments, so “control” depends on which decisions matter most to the buyer.
Can a foreign investor start below 51% and increase ownership later?
Yes. Many transactions begin with a minority or near-majority stake and use a call option or pre-agreed put/call mechanism to increase ownership over time, subject to foreign-ownership limits in the relevant sector and any conditions attached to the original investment registration.

Key takeaways before acquiring a Vietnamese company
Before acquiring a Vietnamese company at any threshold, buyers should confirm the statutory basis for each control right under Vietnam’s Law on Enterprises and the sector-specific commitments in Vietnam’s WTO market-access schedule, since foreign-ownership caps vary significantly by sector. A buyer acquiring a Vietnamese company through a phased structure should map each tranche against these external thresholds, not only against the target’s internal charter.
In summary: acquiring a Vietnamese company at 51% typically secures ordinary control but leaves reserved-matter risk; acquiring a Vietnamese company at 65% closes most of that gap; acquiring a Vietnamese company at 75% or 100% removes most residual minority risk but increases price, approval timeline, and integration burden.
The right threshold for acquiring a Vietnamese company depends on the buyer’s governance objectives, not on the percentage alone.
