Miss a mandatory merger notification filing Vietnam requirement and the consequences are not procedural — they are financial and structural. Under Vietnam’s Competition Law No. 23/2018/QH14 and Decree 35/2020/ND-CP, closing an economic concentration that should have been notified, or closing before clearance is granted (so-called gun-jumping), exposes the parties to fines calculated as a percentage of turnover and, in the worst case, an order unwinding the transaction. Yet many deal teams still treat merger-control analysis as an afterthought, run once by outside counsel a week before signing, rather than as a workstream that shapes the transaction timetable from the term sheet onward.
This guide walks through a merger notification filing Vietnam process end to end: how to determine whether a filing is required, what the notification file must contain, how the National Competition Commission (NCC) reviews it, and how to sequence the filing against signing and closing so the deal timetable survives contact with the regulator.
Why a Merger Notification Filing Vietnam Requirement Exists in the First Place
Vietnam’s merger-control regime exists to catch “economic concentrations” — mergers, consolidations, acquisitions of shares or assets, and joint ventures — that could substantially reduce competition in a relevant market. Unlike jurisdictions with a single bright-line size test, Vietnam applies several alternative thresholds (see this analysis of the Competition Law’s merger-review mechanism), so a transaction can trigger a mandatory merger notification filing Vietnam requirement even where the deal value looks modest by international standards, and conversely can fall outside the regime even for a fairly large transaction if none of the parties has meaningful Vietnam-linked assets, revenue or market share.
Because the tests are alternative rather than cumulative, the notification analysis has to be run early and on the actual numbers for both sides of the transaction, not just the target. A common structuring mistake is assuming that a small Vietnamese target automatically falls outside scope; if the acquirer itself has a large existing Vietnam business in an overlapping or vertically related market, the combined position can still cross a threshold that triggers a merger notification filing Vietnam obligation.
Deal counsel who run this analysis only once, late in the process, routinely discover the merger notification filing Vietnam question too late to build proper lead time into the transaction schedule. Running the threshold test at term-sheet stage, rather than at signing, is what separates a filing that fits neatly into the deal timetable from one that forces a renegotiated long-stop date.
Step 1: Determine Whether Your Deal Meets a Merger Notification Filing Vietnam Threshold
Under Decree 35/2020/ND-CP, a transaction requires a merger notification filing Vietnam submission if it meets any one of four alternative thresholds, measured for the parties (including their corporate groups) in the relevant fiscal year.
Total Asset Value
A filing is required where either party’s total assets in the Vietnam market reach the regulatory threshold set for its sector — VND 3,000 billion for general industries, and a higher threshold for insurance, securities and banking, which are measured against sector-specific benchmarks rather than the general figure.
Total Revenue
A parallel revenue-based test applies to the parties’ total turnover generated in the Vietnam market in the preceding fiscal year, again set higher for regulated financial sectors than for general industry.
Transaction Value
Separately, a filing is required where the value of the economic concentration itself — the deal value — exceeds the applicable threshold, regardless of the parties’ overall size. This test catches transactions involving otherwise small players where the deal itself is large relative to the market.
Combined Market Share
Finally, a filing is required where the parties’ combined market share in the relevant product and geographic market reaches 20% or more, following a competition-law market definition exercise rather than a loose commercial estimate. [Regulator Practice / Verification Required — confirm current VND thresholds and any sector-specific figures against the applicable decree in force at the time of filing, since these amounts have been periodically revised.]
Getting this threshold analysis right at the outset is the single highest-leverage step in the entire merger notification filing Vietnam process, because every later step — file preparation, submission timing, and closing mechanics — depends on knowing which track the transaction is on.
Step 2: Run the Safe-Harbour and De Minimis Analysis
Before assuming a merger notification filing Vietnam obligation applies, check whether the transaction qualifies for an automatic clearance safe harbour. Vietnamese merger-control rules generally exempt concentrations where the combined market share of the parties remains below a low threshold, or where the resulting entity would not rank among a small group of firms that collectively dominate the relevant market.
This safe harbour matters commercially: many bolt-on acquisitions by strategic buyers in fragmented Vietnamese sectors — retail, F&B, light manufacturing — will clear this test comfortably without a substantive merger notification filing Vietnam review, while a consolidation move by an already-dominant player will not.
Step 3: Assemble the Notification File
Once a merger notification filing Vietnam obligation is confirmed, the parties must prepare a notification file for submission to the NCC before closing. Vietnamese merger control is suspensory — closing ahead of clearance is a separate violation from failing to notify at all, and both carry distinct fines.
Core Documentary Requirements
The notification file typically includes corporate documents for each party (charter, business registration, ownership structure), financial statements for the preceding two years, a description of the transaction structure and rationale, and a market analysis identifying the relevant product and geographic markets together with the parties’ market shares. Where the parties’ own market-share calculation is contestable, it is worth commissioning an independent market study rather than relying solely on internal commercial estimates, since the NCC can and does request supplementary data.
Draft Definitive Agreements
The NCC will also expect to see the transaction’s legal documentation — at minimum a signed term sheet or, more commonly, an executed share purchase or merger agreement conditioned on regulatory clearance. This is one reason merger-control timing should be built into the signing mechanics: the notification cannot realistically proceed until the deal terms are locked down in writing, which pushes against a filing strategy that tries to notify before signing is complete.
Deal teams preparing a merger notification filing Vietnam dossier should also assign a single internal owner for the file, since NCC information requests during review often need fast turnaround from finance, legal and commercial teams simultaneously.
Step 4: Submit the Merger Notification Filing Vietnam Dossier to the NCC
The completed notification file is submitted to the NCC, which conducts a two-phase review. This is the procedural core of any merger notification filing Vietnam timeline, and deal teams should build both phases into the transaction schedule from the outset rather than assuming the shorter phase will apply.
Phase 1: Preliminary Review
The NCC has a statutory period — generally 30 days from receipt of a complete file — to conduct a preliminary assessment. Most straightforward transactions, particularly those with limited market overlap between the parties, are cleared at this stage without moving to a full investigation.
Phase 2: Official (Detailed) Review
Where the preliminary review identifies a potential competitive concern, or where the transaction involves a genuinely significant combined market position, the NCC moves to an official review period of up to 90 days, extendable by a further 60 days for particularly complex cases. During this phase, the NCC can request additional information, commission independent market studies, and consult third parties, including competitors and customers of the merging parties.
Outcomes: Clearance, Conditional Clearance or Prohibition
At the end of its review, the NCC issues one of three outcomes: unconditional clearance, clearance subject to behavioural or structural conditions (such as divestiture of an overlapping business line), or prohibition of the transaction. A prohibition decision must set out the competitive basis for the finding, giving the parties a factual record to assess whether restructuring the deal could address the regulator’s concerns. Whichever outcome results, it closes out the formal merger notification filing Vietnam process for that transaction, subject only to any ongoing compliance conditions attached to a conditional clearance.
Step 5: Manage the Interim Period and Closing Mechanics
Because Vietnam’s regime is suspensory, the parties cannot complete the transaction — meaning transferring shares, assets, or control — before clearance is obtained, even if commercial closing conditions are otherwise satisfied. Deal documentation should reflect this explicitly.
Structuring the Long-Stop Date for a Merger Notification Filing Vietnam Timeline
Given the potential for a 30-day review to extend to a combined 90- or even 150-day process, the long-stop date in the transaction agreement needs enough headroom to accommodate a worst-case review timeline, with a mechanism for either party to walk away, or renegotiate, if clearance is delayed materially beyond the base case. Building merger-control approval in as a condition precedent, rather than treating it as a closing formality, is the discipline that protects both sides from a mismatched timetable on any merger notification filing Vietnam deal.
Interim Operating Covenants
Between signing and clearance, the target should generally continue to be run independently of the buyer, with interim covenants restricting the buyer’s ability to direct day-to-day operations. This avoids a separate gun-jumping risk: exercising a level of control over the target before clearance can itself be treated as a premature implementation of the concentration — a risk that a well-run merger notification filing Vietnam process manages through carefully drafted interim covenants rather than informal assurances.
Frequently Asked Questions
What triggers a mandatory merger notification filing in Vietnam?
A filing is triggered where the transaction meets any one of four alternative thresholds under Decree 35/2020/ND-CP: total asset value, total revenue, transaction value, or combined market share of 20% or more in the relevant market. Because the tests are alternative, a deal can trigger a merger notification filing Vietnam requirement through any single threshold, even if the others are not met.
Which authority reviews a Vietnam merger notification filing?
The National Competition Commission (NCC) is the authority responsible for receiving and reviewing merger notifications under the Competition Law No. 23/2018/QH14 and its implementing decrees.
How long does a merger notification filing Vietnam review take?
A preliminary review generally runs 30 days from a complete filing. If the NCC identifies a potential competition concern, the review moves to an official phase of up to 90 days, extendable by a further 60 days in complex cases — meaning parties should plan for a total review window that could reach roughly 150 days in a worst-case scenario.
Can a transaction close before merger-control clearance is obtained?
No. Vietnam’s regime is suspensory, meaning the parties must obtain clearance before completing the transaction. Closing early, or exercising practical control over the target before clearance, exposes the parties to gun-jumping penalties separate from any failure-to-notify fine.
What happens if a party fails to make a required merger notification filing?
Failure to notify a transaction that meets a mandatory threshold can result in a fine calculated as a percentage of the offending party’s turnover, and the NCC can, in serious cases, order remedial measures including divestiture. The financial exposure scales with company size, which makes the notification analysis a priority workstream for larger strategic buyers in particular.
Does a foreign-to-foreign transaction with no Vietnamese subsidiary ever require a Vietnam merger notification filing?
It can. Vietnamese competition authorities have taken the position that offshore transactions are notifiable where the parties meet the relevant thresholds by reference to their Vietnam-linked business, even without a locally incorporated subsidiary, so cross-border deal teams should not assume a lack of local incorporation puts a transaction outside scope.

How IVLF Supports Merger Notification Filings in Vietnam
A merger notification filing Vietnam analysis needs to happen before signing, not after — the earlier a deal team understands whether a filing is required and which review track is likely, the more realistically the transaction timetable, long-stop date and closing mechanics can be structured. IVLF advises strategic acquirers and private equity sponsors as M&A legal counsel Vietnam clients rely on to run the threshold analysis, prepare and submit the notification file, and manage engagement with the National Competition Commission through to clearance.
As Vietnam M&A lawyer advisers with experience across regulated and unregulated sectors, our team also supports acquirers who need cross-border M&A counsel Vietnam can coordinate with home-jurisdiction antitrust counsel on a single, unified filing strategy where a transaction requires notification in multiple jurisdictions simultaneously.
If your organisation is planning an acquisition, joint venture or consolidation that may require a merger notification filing Vietnam submission, IVLF’s M&A advisory Vietnam team can assess the thresholds early and build the filing into your transaction plan rather than discovering it late. For related reading, see IVLF’s guides to when a Vietnam M&A deal requires merger-control filing and to building a deal structure diagram for a Vietnam M&A transaction, as well as our sector guide to insurance-sector M&A in Vietnam, where merger-control thresholds are set higher than for general industry.
