M&A Lawyers Vietnam 2026: Decree 102, Merger‑control Notifications & Gun‑jumping Penalties

Vietnam’s merger‑control landscape shifted decisively in early 2026, and M&A lawyers in Vietnam are now advising deal teams to recalibrate every live transaction against a tougher regulatory framework. The Investment Law 2026, effective 1 March 2026, introduced new foreign‑investor approval requirements for several sectors, including real estate, while Decree 102/2026, issued in April 2026, overhauled the economic‑concentration notification rules and significantly raised the penalties for non‑compliance. The combined effect is that acquirers, targets and joint‑venture parties face a wider set of filing triggers, shorter practical timelines and, from 20 May 2026 onward, administrative fines of up to VND 2 billion for failure to notify.

This article provides the practical compliance playbook that general counsel, private‑equity sponsors and transaction lawyers need: a step‑by‑step filing checklist, a penalties matrix, sample anti‑gun‑jumping drafting language and three real‑world risk scenarios drawn from current deal patterns in Vietnam.

Overview of the 2026 Reforms: Investment Law 2026 & Decree 102/2026

Two pieces of legislation now dominate the regulatory environment for M&A in Vietnam. Understanding how they interact, and where they diverge, is the first step in any pre‑deal compliance screen.

The Investment Law 2026 came into force on 1 March 2026 and replaced certain provisions of the prior investment‑licensing regime. For M&A deal teams, the most material changes relate to the approval process for foreign investors acquiring stakes in conditional business lines and in enterprises holding land‑use rights. Transactions in sectors such as real estate, education and telecommunications now require an expanded set of pre‑closing approvals from the Department of Planning and Investment (DPI) or, in certain cases, the Prime Minister’s office. Industry observers expect these additional approval gates to add between two and six weeks to deal timelines where foreign ownership triggers apply.

Decree 102/2026, issued in April 2026, directly amends the sanctions and procedural framework established by Decree 75/2019/ND‑CP. Its primary objectives are to sharpen the economic‑concentration notification thresholds, expand the categories of conduct that constitute gun‑jumping, and substantially increase the range of administrative fines available to the Vietnam Competition Commission (VCC). According to the official text published on the national legal database, the revised penalty provisions become practically enforceable from 20 May 2026.

Timeline of Key Legislative Dates

How Decree 102 Amends Decree 75/2019

Decree 75/2019 established Vietnam’s original sanctions framework for competition‑law violations, including the fines applicable to economic concentrations carried out without prior notification. Decree 102/2026 amends Decree 75 in three principal respects. First, it raises the ceiling for administrative fines for failure to notify an economic concentration, with reported maximum fines of up to VND 2 billion. Second, it clarifies the categories of conduct that amount to gun‑jumping, including the exercise of voting rights, the appointment of directors or senior management, and the integration of commercial operations before clearance is obtained. Third, it streamlines the VCC’s procedural toolkit for investigating suspected violations, reducing the evidentiary thresholds for the authority to open a formal inquiry.

Merger‑Control Notification Triggers Under Decree 102/2026

Vietnam’s Competition Law 2018 defines “economic concentration” broadly to capture mergers, consolidations, acquisitions (of shares or assets) and joint ventures. The obligation to notify the VCC, the Vietnam competition authority, arises whenever the parties to a proposed economic concentration meet any one of several quantitative thresholds. Decree 102/2026 refines how those thresholds are calculated and, critically, how the revenue and assets of related parties are aggregated.

The notification triggers operate as alternative tests: a filing is required if any single threshold is met. The principal thresholds under the Competition Law 2018 (as further implemented by Decree 102/2026) include total assets of the participating enterprises, total revenue in the Vietnamese market, combined market share, and transaction value. Where the relevant threshold is met, notification is mandatory regardless of whether there is any horizontal overlap between the parties’ activities. This is a point that M&A lawyers in Vietnam regularly emphasise to foreign sponsors unfamiliar with the Vietnamese regime: a purely vertical or conglomerate transaction can still trigger a filing obligation.

Who Counts as a “Party/Enterprise” for Threshold Aggregation?

Decree 102/2026 adopts the concept of an “enterprise group” for the purpose of calculating thresholds. This means that the total assets and total revenue of all enterprises within the same corporate group, including parent companies, subsidiaries and affiliates, are aggregated when assessing whether a threshold is breached. For private‑equity sponsors, this is particularly significant: the aggregation captures all portfolio companies under common control, not merely the direct acquirer and the target.

The likely practical effect of this aggregation rule is that a greater number of transactions will cross the notification thresholds, even where the acquiring entity itself is a small special‑purpose vehicle. Deal teams should conduct threshold calculations at the ultimate parent level and include all Vietnamese‑market revenue of affiliated entities.

Examples, Share Acquisitions, Asset Deals, Joint Ventures

It is worth underscoring that notification obligations apply even where the parties operate in entirely different product or geographic markets. The Vietnamese regime does not include a “de minimis” market‑share safe harbour of the kind found in some other ASEAN jurisdictions. Early engagement with M&A lawyers in Vietnam who specialise in merger control is therefore essential to avoid inadvertent non‑compliance.

Filing Process, Timeline & Documents for M&A Regulatory Clearance

Once a deal team confirms that a notification is required, the filing must be made to the VCC, the designated Vietnam competition authority responsible for reviewing economic‑concentration notifications. The process involves several distinct stages, each with its own documentary requirements and statutory time limits.

Standard Filing Forms and Supporting Documents

The economic concentration notification dossier typically includes the following:

• Notification form. The prescribed VCC form, completed in Vietnamese, identifying the parties, the structure of the transaction and the basis on which thresholds are met.
• Corporate documents. Enterprise registration certificates, charters/articles of association, and organisational charts for each filing party and its group.
• Financial statements. Audited financial statements for the most recent two fiscal years for each party and its group, showing total assets and Vietnamese‑market revenue.
• Market‑share data. Information on the parties’ market shares in relevant product and geographic markets in Vietnam, including third‑party reports where available.
• Competition analysis. A description of the competitive landscape, identification of key competitors, and an assessment of the transaction’s likely impact on competition.
• Transaction documents. Copies of the signed or near‑final SPA, SHA, JV agreement, or asset purchase agreement.
• Real‑estate titles. Where the target holds land‑use rights, copies of land‑use‑right certificates and related approvals (now cross‑referenced with Investment Law 2026 requirements).
• Power of attorney. If filed through counsel, a notarised and legalised power of attorney authorising the filing representative.

Typical Review Stages and Statutory Timelines (Days)

Experienced M&A lawyers in Vietnam consistently advise that the pre‑notification meeting, while not legally mandatory, is the single most effective step for shortening the overall review period. The VCC is receptive to early engagement, and pre‑notification discussions allow counsel to identify potential objections and tailor the filing accordingly, often avoiding stop‑the‑clock delays during Phase I.

Gun‑Jumping Penalties Vietnam: The Enforcement & Penalties Matrix

The penalty regime under Decree 102/2026 represents a step change in Vietnam’s approach to competition enforcement. Before these amendments, administrative fines for failure to notify an economic concentration were comparatively modest. The revised framework raises the stakes considerably, and deal teams must now treat gun‑jumping risk with the same seriousness as they would in the EU or the United States.

Enforcement Trends & Recent Examples

The VCC has signalled a more assertive enforcement posture in its public communications throughout 2025 and early 2026. Industry observers expect Decree 102/2026 to be applied proactively, particularly to high‑profile transactions involving foreign investors. The reported VND 2 billion maximum fine for failure to notify, a figure corroborated by the national legal database, represents a significant uplift from historical penalty levels and is designed to serve as a meaningful deterrent.

Early indications suggest that the VCC will focus its enforcement resources on three categories of conduct: (a) completed transactions where no notification was filed at all; (b) transactions where the parties filed but closed before receiving formal clearance; and (c) transactions where the acquirer began exercising de facto control, appointing management, redirecting commercial strategy or integrating IT systems, during the review period.

Mitigation & Remedial Steps After a Breach

If a breach has already occurred or is suspected, counsel should consider the following immediate steps:

• Voluntary self‑disclosure. Approaching the VCC proactively and disclosing the breach before it is detected can be a mitigating factor in the authority’s penalty assessment.
• Retrospective filing. Filing the economic concentration notification as soon as the breach is identified, accompanied by a full explanation of the circumstances.
• Suspension of integration. Immediately halting any integration activity, reverting management appointments, and ring‑fencing the target’s operations until clearance is obtained.
• Hold‑separate agreement. Executing a formal hold‑separate agreement between the parties, with an independent monitor if necessary, to demonstrate that competitive independence has been preserved.

Deal Structuring & Compliance Checklist: Why Instruct M&A Lawyers in Vietnam Now

The combination of the Investment Law 2026 and Decree 102/2026 creates a compliance matrix that is significantly more complex than the one deal teams faced even twelve months ago. A structured, pre‑deal screening process is now essential for any transaction involving Vietnamese assets, entities or markets.

Obligation by Entity Type

Template Clauses and Red‑Flag Checklist

Buy‑side and sell‑side counsel should build the following protections into every SPA or SHA for transactions that may trigger Vietnam merger control:

• Condition precedent (CP) for merger‑control clearance. The SPA should include an express CP requiring VCC clearance before completion can occur. Sample language: “Completion shall not occur unless and until the VCC has issued a decision approving the Transaction, or the statutory review period has expired without the VCC issuing a prohibition or a request for an in‑depth review.”
• Hold‑separate undertaking. A standalone schedule or side letter in which the acquirer undertakes not to exercise any voting rights, appoint or remove directors, direct commercial strategy, or access competitively sensitive information of the target until clearance is received.
• Long‑stop date with regulatory extension. Include a long‑stop date that can be extended by mutual agreement if the VCC review is ongoing, to prevent the deal from terminating solely because Phase II takes longer than expected.
• Clean‑team / information‑barrier protocol. Restrict the exchange of competitively sensitive information during due diligence and the review period to a defined “clean team” of advisers and designated individuals.
• Interim operating covenants. The target undertakes to operate the business in the ordinary course and not to make material changes to operations, pricing or staffing without the acquirer’s consent (which itself must be exercised carefully to avoid gun‑jumping).

When to Seek Informal Guidance from the VCC

The VCC has demonstrated a willingness to engage in informal, pre‑notification discussions with deal parties and their counsel. This channel is particularly valuable where the transaction structure is novel, where the threshold analysis is borderline, or where the parties anticipate that the VCC may have competitive concerns. Counsel should prepare a short briefing paper summarising the transaction, the parties’ Vietnamese operations, and the preliminary competition analysis before requesting a meeting. The VCC typically responds to meeting requests within five to ten business days.

Real‑World Risk Scenarios & Recommended Responses

To illustrate how the 2026 reforms operate in practice, the following three scenarios reflect deal patterns that M&A lawyers in Vietnam are currently advising on.

Scenario 1, Urgent public takeover with a 30‑day close window. A foreign strategic buyer launches a voluntary tender offer for a listed Vietnamese company. The combined group exceeds the total‑asset threshold. The buyer’s commercial team wants to close within 30 calendar days of announcement. Recommended response: File the economic concentration notification concurrently with the tender‑offer launch. Engage the VCC in pre‑notification discussions before announcement (under NDA). Include a regulatory CP in the offer document. Do not acquire any tendered shares until Phase I clearance is received. If Phase II is triggered, extend the offer period and notify the State Securities Commission accordingly.

Scenario 2, PE buyout with cross‑border assets. A regional PE fund acquires a Vietnamese manufacturing platform that also has subsidiaries in Thailand and Indonesia. The fund’s existing portfolio includes a Vietnamese logistics company. Recommended response: Aggregate the Vietnamese‑market revenue and assets of the fund’s entire portfolio (including the logistics company) when calculating thresholds. File in Vietnam even if no horizontal overlap exists. Coordinate with antitrust counsel in Thailand and Indonesia for parallel filings. Use a hold‑separate agreement to ring‑fence the logistics company’s operations until clearance is obtained in all relevant jurisdictions.

Scenario 3, Real‑estate‑heavy transaction post‑Investment Law 2026. A foreign investor acquires a Vietnamese company whose principal asset is a portfolio of land‑use‑right certificates for industrial‑park development. Recommended response: The deal triggers both (a) the DPI foreign‑investor approval process under the Investment Law 2026 and (b) an economic concentration notification to the VCC (if thresholds are met). Run both approval workstreams in parallel. Ensure that the SPA contains CPs for both regulatory approvals. Prepare land‑use‑right documentation early, as the DPI will require certified copies of all certificates and evidence that the target’s land‑use rights are valid and unencumbered.

Conclusion

The regulatory environment for M&A in Vietnam is materially more demanding in 2026 than it was a year ago. The Investment Law 2026 and Decree 102/2026 together require deal teams to screen every transaction against a wider set of filing triggers, prepare more comprehensive notification dossiers, and implement robust anti‑gun‑jumping protections in transaction documentation. The consequences of non‑compliance, fines of up to VND 2 billion, potential unwinding of completed transactions, and reputational damage with the VCC, make early, expert legal guidance indispensable.

For general counsel, private‑equity sponsors and strategic acquirers planning transactions in Vietnam, the immediate action items are clear: re‑screen every pipeline deal against the new thresholds, update template SPA and SHA clauses to include merger‑control CPs and hold‑separate undertakings, and engage experienced M&A lawyers in Vietnam before signing. The penalties for getting this wrong are now substantial. The cost of getting it right, a well‑prepared filing and a disciplined pre‑closing protocol, is a fraction of the risk.
