How to Structure Cross‑border M&A in Vietnam After the Investment Law 2026: a Practical Playbook for Buyers and Sellers

Last reviewed: 16 May 2026

Structuring M&A in Vietnam has become materially more complex since the Investment Law 2026 came into force, reshaping approval pathways, tightening the definition of “indirect acquisition,” and reinforcing the Vietnam Competition Authority’s (VCA) enforcement posture on merger-control thresholds. For general counsel, private-equity sponsors, and strategic acquirers evaluating a cross-border acquisition in Vietnam, the central question is now a three-part compliance decision: can the deal proceed as a direct share purchase, an asset transfer, or an upstream holding-company acquisition, and which regulatory approvals will each structure trigger? This playbook maps those structuring choices to the new legal framework, provides realistic timelines, and offers practical checklists designed to reduce closing risk in 2026 transactions.

Executive Summary and the Primary Structuring Decision

Every inbound M&A transaction in Vietnam now starts with a single compliance gateway: identifying the correct deal structure and its corresponding approval burden under the Investment Law 2026 and its implementing decrees. A misjudged structure can add months to a timeline, trigger unexpected foreign-ownership restrictions, or, in the worst case, expose a completed transaction to unwinding risk.

The decision rule for structuring M&A in Vietnam can be condensed into three questions that should be answered before any term sheet is signed:

• Does the target operate in a sector subject to foreign-ownership caps or conditional market-access commitments? If yes, a share purchase may require sectoral approvals beyond standard investment registration, and an asset purchase should be evaluated as an alternative.
• Will the combined entity breach VCA notification thresholds on turnover, total assets, or market share? If yes, merger-control filing must be factored into the timeline regardless of deal structure.
• Is the buyer acquiring shares in an offshore parent rather than the Vietnamese entity directly? If yes, the Investment Law 2026’s expanded definition of indirect acquisition may still apply, and the regulatory approvals for Vietnam may follow the transaction regardless of the offshore wrapper.

The sections that follow map each answer to the practical steps, approval bodies, timelines, and risk-mitigation tools that experienced deal teams are using in the current market.

What Changed: Investment Law 2026, Key Practical Points for M&A

The Investment Law 2026 replaced its 2020 predecessor with several provisions that directly affect how foreign buyers structure acquisitions. Industry observers expect these changes to increase both the time and cost of regulatory compliance for mid-market and large-cap transactions.

New Approval Triggers and Definitions

The most consequential change for cross-border acquisition in Vietnam is the broadened scope of what constitutes an “indirect foreign investment.” Under the Investment Law 2026, a transaction that results in a foreign investor gaining control, or a decisive influence over business decisions, of a Vietnamese enterprise may be treated as a direct foreign investment, even if the shares acquired are those of an offshore holding company. This closes a structuring pathway that many sponsors previously relied upon. The law also introduces refined conditions for investment registration certificates (IRCs) and enterprise registration certificates (ERCs), creating additional filing steps when foreign ownership crosses prescribed thresholds.

Interaction with Decrees and Implementing Guidance

The Investment Law 2026 does not operate in isolation. Its implementing decrees, notably Decree No. 96/2026/ND-CP on investment registration procedures and Decree No. 103/2026/ND-CP on outward-investment changes, fill critical procedural gaps. Decree No. 96/2026/ND-CP, for example, clarifies the documentation requirements and timelines for IRC amendments triggered by share transfers to foreign acquirers. The interaction between these instruments and existing sectoral regulations (banking, telecoms, energy) creates a layered approval matrix that must be mapped transaction-by-transaction.

Practical Takeaway, Spotting the New Risks Early

Deal teams should conduct a regulatory-mapping exercise as early as the letter-of-intent stage. The key risk indicators are: (a) the target operates in a conditionally accessible sector; (b) the transaction shifts foreign ownership above a statutory threshold; or (c) the buyer’s proposed structure involves an offshore intermediate entity. Any of these triggers warrants specialist regulatory counsel before commercial terms are finalised.

Primary Deal Structures for Structuring M&A in Vietnam

Foreign acquirers in Vietnam typically choose from four deal structures. Each carries distinct regulatory approvals in Vietnam, risk profiles, and post-closing obligations. The practical choice often depends on the target’s sector, the buyer’s appetite for assuming legacy liabilities, and the time available before commercial deadlines.

Share Purchase, Process, Approvals, Advantages and Common Pitfalls

A share purchase is the most common structure for cross-border acquisitions. The buyer acquires equity in the Vietnamese target, preserving its existing contracts, licences, and workforce. Under the Investment Law 2026, the share transfer must be registered with the Department of Planning and Investment (DPI) if it results in a foreign investor holding shares for the first time, or if a foreign investor increases its stake above a prescribed level. Sectoral licences, banking, telecoms, energy, may require separate approval from the relevant line ministry. The principal pitfall is triggering foreign-ownership limits in Vietnam: once the foreign-held equity exceeds the cap for a given sector, the DPI will not register the transfer.

Asset Purchase, Process, Approvals, Advantages and Pitfalls

An asset purchase allows the buyer to cherry-pick specific assets, plant, equipment, intellectual property, select contracts, while leaving unwanted liabilities with the seller. This structure can sometimes avoid foreign-ownership restrictions because the buyer is not acquiring equity in a Vietnamese enterprise. However, asset-specific licences may not be transferable, requiring the buyer to apply for new permits. Transfer of land-use rights, in particular, involves separate registration with the local Department of Natural Resources and Environment, and rights of foreign individuals and organisations to real estate in Vietnam are subject to specific conditions that must be verified during diligence.

Merger and Statutory Consolidation

A statutory merger involves one company absorbing another, with the absorbed entity ceasing to exist. This route is less common in foreign inbound transactions because it requires compliance with both the Enterprise Law and Investment Law simultaneously, creating a heavier approval burden. It is typically reserved for restructurings within existing corporate groups rather than arm’s-length acquisitions.

Upstream Acquisition, When It Works and When It Fails

Buying the offshore parent company that holds the Vietnamese subsidiary was historically a way to avoid direct Vietnamese regulatory filings. The Investment Law 2026’s expanded indirect-acquisition provisions have substantially narrowed this pathway. Regulators may now look through the offshore structure and treat the transaction as a change of control of the Vietnamese entity, applying the same approval requirements as a direct share purchase. Early indications suggest that authorities are scrutinising upstream acquisitions with greater frequency.

Merger Control in Vietnam and VCA Notification

Vietnam’s merger-control regime requires parties to notify the VCA before completing any economic concentration that meets prescribed thresholds. The VCA’s enforcement posture has tightened measurably since 2024, and practitioners report that informal consultations with the authority are becoming more common, and more scrutinous, in 2026 transactions.

Current VCA Notification Thresholds and Enforcement Trends

Under the Competition Law and its implementing decrees, notification is mandatory when the combined parties meet any one of several tests: total assets or total revenue in the Vietnamese market exceeding prescribed monetary thresholds, or a combined market share in the relevant market at or above 20 percent. The VCA has issued periodic guidance updating the monetary values; deal teams must verify the current figures at the time of filing, as the thresholds are adjusted. Recent enforcement trends indicate that the VCA is paying closer attention to technology, consumer goods, and renewable-energy transactions, sectors experiencing consolidation in 2026. Parties that fail to file, or that complete a transaction before clearance, face penalties including fines and potential unwinding orders.

Filing Process, Timeline and Penalties

The VCA filing process follows a two-phase structure. The initial review typically takes 30 to 45 days from acceptance of a complete filing. If the VCA identifies competition concerns, it may initiate a detailed (Phase II) review, which can extend the process to 90 days or longer. During the review period, the parties are prohibited from completing the transaction. Penalties for gun-jumping, completing the deal before clearance, include administrative fines and, in theory, an order to restore the pre-transaction competitive conditions.

Practical Mitigation Strategies

Experienced deal teams manage merger control in Vietnam through several tools: pre-filing consultations with VCA staff (to pressure-test the competition analysis before formal submission), carve-out structures that remove overlapping business lines from the transaction perimeter, and hold-separate arrangements that prevent integration during the review period. Including a regulatory walkaway right in the SPA, triggered if clearance is not obtained within a specified long-stop date, protects the buyer from indefinite delay.

Sectoral Foreign Ownership Limits and Red-Flag Sectors

Foreign ownership limits in Vietnam are governed by a combination of the Investment Law 2026, Vietnam’s WTO commitments, and sector-specific legislation. The negative list, formally the list of business lines with conditions for foreign investors, determines the maximum permissible foreign stake in each sector. Understanding these caps is essential when structuring M&A in Vietnam because they directly dictate whether a share purchase is feasible or whether an alternative structure is required.

Banks and Financial Institutions

Foreign ownership in Vietnamese commercial banks is capped at 30 percent in aggregate, with a single foreign institutional investor limited to 20 percent (strategic investors may be permitted up to 20 percent under specific State Bank of Vietnam approval). These caps make full acquisitions of listed banks impossible through direct share purchases, driving buyers toward minority-stake structures, joint ventures, or negotiated strategic-investor arrangements.

Real Estate and Land-Use-Sensitive Assets

Foreign-invested enterprises may hold land-use rights, but the scope of permitted activities and the duration of allocation are restricted compared with domestic enterprises. Acquisitions involving significant land banks, industrial parks, residential developments, resort projects, require careful due diligence on the rights of foreign organisations to real estate in Vietnam to confirm that the target’s existing land-use rights will survive a change of ownership.

Renewables and Infrastructure

Vietnam’s rapidly growing renewable-energy sector attracts substantial foreign investment, but ownership restrictions apply to power-generation and transmission projects under electricity-sector regulations. Foreign investors may hold up to 100 percent in certain generation projects but face restrictions on grid infrastructure. Structuring choices in this sector frequently involve build-operate-transfer or public-private-partnership frameworks alongside conventional M&A.

Telecom, Media, and Defence-Related Sectors

Telecommunications services are subject to caps ranging from 49 percent to 65 percent depending on the specific licence category. Media and press remain effectively closed to foreign ownership. Defence-related industries appear on the prohibited list entirely. Buyers targeting portfolio companies with even ancillary operations in these sectors must verify exposure during diligence.

How the Negative List Changes Structuring Choices

Where the negative list imposes a cap below the buyer’s desired ownership level, the practical options are: (a) structure a minority-stake investment with governance protections (board seats, veto rights, information covenants); (b) pursue an asset purchase to acquire specific business lines without triggering the equity cap; or (c) negotiate a phased acquisition aligned with anticipated regulatory liberalisation.

M&A Due Diligence and Pre-Filing Checklist Under Investment Law 2026

Thorough M&A due diligence in Vietnam is the buyer’s first line of defence against post-closing surprises. The Investment Law 2026 has raised the stakes by introducing additional filing triggers and tightening the consequences of non-compliance. The checklist below is organised into three workstreams.

Legal, Title, and Licence Checks

• Corporate chain: confirm the target’s registered capital, actual contributed capital, and shareholder register, discrepancies are common and can delay DPI registration.
• Investment registration certificate (IRC): verify that the IRC is current, that all business lines match the target’s actual operations, and that no pending amendments are outstanding.
• Sectoral licences: map every licence required for the target’s operations (e.g., drug registration, telecoms permits, environmental clearances) and assess transferability or re-issuance requirements post-closing.

Regulatory and Compliance

• Foreign-ownership status: calculate current and post-transaction foreign-ownership percentages against the negative list.
• Land-use rights: confirm allocation type (lease vs. assignment), remaining term, permitted use, and any government clawback rights.
• Local-authority approvals: certain provinces require additional People’s Committee endorsements for investment activities; verify whether the target’s location triggers these requirements.

Tax, Employment, and Material Contracts

• Tax compliance: review corporate income tax, VAT, and personal income tax withholding obligations; assess transfer-pricing exposure for related-party transactions.
• Employment: verify social-insurance contributions, outstanding labour disputes, and collective bargaining agreements, Vietnamese labour law imposes automatic transfer-of-employment obligations in certain deal structures.
• Material contracts: identify change-of-control provisions, assignment restrictions, and government-contract termination triggers. Consular legalisation of foreign documents may be required for evidentiary purposes during diligence.

Timelines, Closing Risk, and Deal Mechanics

Regulatory clearance timelines in Vietnam vary significantly depending on the deal structure, the sectors involved, and whether a VCA filing is required. Early indications from 2026 transactions suggest that overall timelines have lengthened by approximately two to four weeks compared with deals completed under the previous Investment Law, primarily due to additional filing steps introduced by Decree No. 96/2026/ND-CP.

Sample Timeline for Common Transaction Patterns

Closing Risk Management

The primary closing risks in Vietnamese M&A are regulatory delay, filing rejection, and post-signing changes in the target’s compliance status. Buyers should deploy the following tools:

• Escrow and holdbacks: retain a portion of the purchase price (typically 5–15 percent) in escrow pending completion of all post-closing registrations and satisfaction of indemnity periods.
• Condition precedents: tie closing to receipt of all regulatory approvals, including DPI registration, sectoral clearances, and VCA green light.
• Regulatory walkaway rights: include a contractual right for either party to terminate the SPA if approvals are not obtained by an agreed long-stop date, with clear provisions for break-fee allocation.
• Interim operating covenants: restrict the seller from making material changes to the target’s business, licences, or workforce between signing and closing.

Practical Drafting and Negotiation Tips for Structuring M&A in Vietnam

Transaction documents for Vietnamese cross-border deals must address risks specific to the Investment Law 2026 framework. The following drafting guidance reflects emerging market practice, all sample language is illustrative only and should be adapted with the assistance of qualified Vietnamese counsel.

Representations and Warranties Checklist

Vietnam-specific reps should cover:

• Foreign-ownership compliance: the seller warrants that the target’s current and post-closing foreign-ownership levels comply with the negative list and all applicable sectoral caps.
• Licence continuity: all material licences, permits, and government approvals are valid, in full force, and will not be revoked, suspended, or materially altered as a result of the transaction.
• IRC/ERC accuracy: the target’s investment registration certificate and enterprise registration certificate accurately reflect its registered capital, business lines, and investor composition.
• No pending regulatory action: no proceedings, investigations, or orders by any Vietnamese authority are pending or threatened that could affect the target’s operations or the buyer’s ability to complete the acquisition.

Conditional-Closing and Regulatory Termination Language

Sample clause concepts for SPA negotiation:

• Closing condition (regulatory): “Closing shall be conditional upon (i) receipt of the DPI’s confirmation of the amended IRC reflecting the Buyer as a shareholder, (ii) all required sectoral approvals being in full force, and (iii) VCA clearance (whether by approval or expiry of the review period without objection).”
• Long-stop termination: “If all Conditions Precedent have not been satisfied or waived by [Long-Stop Date], either Party may terminate this Agreement by written notice, provided that the terminating Party is not then in material breach of its obligations hereunder.”
• Regulatory break fee: “In the event of termination due solely to non-receipt of regulatory approval by the Long-Stop Date (other than by reason of a Party’s failure to use reasonable efforts), the Buyer shall pay / no break fee shall be payable [as negotiated].”

Post-Closing Integration, Notifications, and Compliance

Post-Closing Filing Obligations

Completion of a Vietnamese M&A transaction triggers several mandatory filings. The buyer must update the enterprise registration certificate with the local business registration office to reflect the new ownership structure. If the transaction involved a change in the IRC, confirmation of that amendment must be obtained and filed. Sectoral regulators, the State Bank of Vietnam for financial institutions, the Ministry of Information and Communications for telecoms, require separate notifications. Employee notifications must comply with the Labour Code, and social-insurance registration must be updated to reflect any changes in the employing entity. Transfer of inheritance and ownership rights related to individual assets may also require attention for deals involving natural-person sellers.

Ongoing Compliance Monitoring and Reporting

Post-closing, the acquired entity must continue to comply with its IRC conditions, sectoral licence terms, and any VCA commitments (behavioural or structural remedies). Annual reporting obligations to the DPI and tax authorities remain unchanged, but the buyer should implement a compliance-monitoring calendar to track renewal dates, reporting deadlines, and any ongoing conditions attached to regulatory approvals. Buyers entering Vietnam for the first time should also ensure that their personnel hold appropriate Vietnam business visas and work permits for any management secondees.

Conclusion: Recommended Playbook Checklist for Structuring M&A in Vietnam

The Investment Law 2026 has raised the complexity of cross-border M&A in Vietnam, but well-prepared deal teams can navigate the new framework efficiently. The following eight-point checklist summarises the essential actions for buyers and sellers:

1. Map the regulatory landscape early, identify applicable foreign-ownership caps, sectoral approvals, and VCA filing obligations at the LOI stage.
2. Choose the right structure, evaluate share purchase, asset purchase, and upstream-acquisition options against the target’s sector, licence profile, and the buyer’s risk appetite.
3. Engage Vietnamese regulatory counsel pre-signing, specialist input on Investment Law 2026 requirements avoids costly mid-transaction corrections.
4. Conduct comprehensive due diligence, focus on IRC/ERC accuracy, licence transferability, land-use rights, and tax compliance.
5. File early and file completely, incomplete VCA or DPI submissions restart the clock; pre-filing consultations reduce this risk.
6. Draft Vietnam-specific protections into the SPA, include foreign-ownership reps, licence-continuity warranties, regulatory conditions precedent, and a long-stop termination right.
7. Manage the gap between signing and closing, use escrow, holdbacks, and interim operating covenants to preserve deal value.
8. Plan post-closing integration from day one, calendar all filing deadlines, licence renewals, and ongoing VCA compliance obligations before the ink dries.
