When this route applies
- A foreign investor acquires or subscribes for shares / capital in a Vietnamese company AND at least one trigger in Investment Law 143/2025/QH15, Art. 21(3) applies:
- (1) the transaction INCREASES the ownership percentage of foreign investors in a company operating in a conditional market-access sector (Art. 21(3)(a)). Both limbs are needed. A conditional business line in the Target is not enough on its own: if foreign investor A sells its 30% to foreign investor B, total foreign ownership stays at 30% and this trigger is not met;
- (2) foreign ownership moves from 50% or less to more than 50%, or increases while already above 50%;
- (3) the target holds a land-use right certificate for land in an island, border or coastal commune, or another area affecting national defence and security.
- M&A registration is NOT an IRC. It is a prior confirmation that the foreign investor meets the conditions to become a member / shareholder. Acquiring shares in a Vietnamese company does not automatically mean that a new IRC is required.

Required approvals
| Approval / registration | Position on this route | Authority |
|---|---|---|
| M&A registration / approval | Required BEFORE closing | Investment registration authority |
| New IRC | Not automatically required | Confirm with counsel |
| Corporate change registration | Required after closing | Business Registration Office |
| Merger control | Potentially required (confirm thresholds with counsel) | Competition authority |
| Sector regulator consent | Case-specific legal review required. | Sector regulator |
Parallel transaction approvals
Separate regimes: none replaces another.
| Approval layer | When it applies | Authority | Relationship to M&A registration |
|---|---|---|---|
| Investment Law M&A registration | One of the Art. 21(3) triggers is met (see section A) | Investment registration authority | This route. R5 = not required; R6 = required before closing |
| Competition: economic concentration notification | Parties meet a notification threshold (confirm thresholds with counsel) | National Competition Commission | Independent of M&A registration. A deal on R5 may still need it. Closing waits for clearance |
| Public-company / securities approval or disclosure | Target is a public or listed company | State Securities Commission; stock exchange; depository | See the public / listed company track below |
| Banking / insurance / securities sector approval | Target is a credit institution, insurer, securities or fund-management company | State Bank of Vietnam; Ministry of Finance; State Securities Commission | Sector law sets its own ownership caps and prior approvals (confirm with counsel). |
| State-capital rules | The seller is the State or a State-owned enterprise | Owner's representative agency | Valuation, auction and approval rules apply to the sale itself (confirm with counsel). |
| Land / project approval | The deal changes the investor of a project, or the Target holds sensitive land | Investment registration authority; land authority | Check existing IRCs and Investment Policy Approvals of the Target; see R7 for asset deals |
| Other regulated-sector approval | Target holds licences that name or depend on its owners (telecom, aviation, education, healthcare, media and others) | Sector regulator | Case-specific legal review required. |
Public / listed company track
Track B: only if the Target is a public or listed company.
- Foreign ownership room: check the cap that applies to the Target (sector cap, charter cap, or the default for public companies) and the room left (confirm with counsel).
- Securities trading code and account: the foreign investor obtains a trading code and opens custody and trading accounts before buying listed or registered shares (confirm with counsel).
- Payment and custody: purchase funds move through the investor's indirect investment account; shares settle through the depository.
- Tender offer: a mandatory public tender offer applies when ownership thresholds are reached or crossed (confirm thresholds and exemptions with counsel).
- Disclosure: major-shareholder, insider and related-person reporting by the buyer and the Target (confirm deadlines with counsel).
- Economic concentration: assess in parallel.
- Investment Law M&A test: run the Art. 21(3) test in the same way as for a private Target. Being listed does not remove it, and passing it does not replace the securities-law steps.
Document checklist
Typical: the authority may ask for more.
- M&A registration form
- Legalised investor documents
- Agreement in principle / conditional SPA or SSA
- Target's ERC, IRC (if any) and list of business lines
- Land-use right certificates of the target (sensitive-land trigger)
- Closing, tax and bank documents as in R5
Critical risks
- Closing before approval (transaction may not be registrable).
- Authority challenges a business line of the target; carve-out needed.
- Staged acquisitions: each step that increases ownership above 50% may need its own registration.
- Timetable slippage where security consultation is required.
When the investor may legally start operations
The investor may start a given business activity only when ALL of the following are in place for that activity: (1) the investment procedure is complete (IRC / approval, where required); (2) the company or other vehicle legally exists (ERC or equivalent); (3) capital has been contributed through the correct account and on schedule; (4) the premises may lawfully be used for the activity; (5) construction, environmental and fire-safety steps that apply are complete; (6) every sector-specific licence for that activity has been issued; and (7) tax, invoicing and employment registrations are done. Use the GO-LIVE CHECKLIST to confirm.
Common mistakes
- Confusing M&A registration with an IRC.
- Forgetting subsidiaries' business lines.
- No long-stop date or restructuring fallback in the SPA.
