Vietnamese merger regulations
Under the Vietnamese Competition Law, an “economic concentration” is defined to include the following types of transactions:
(a) Merger of enterprises means the transfer by one or more enterprise(s) of all of its lawful assets, rights, obligations and interests to another enterprise and at the same time the termination of the existence of the merging enterprise(s).
(b) Consolidation of enterprises means the transfer by two or more enterprises of all of their lawful assets, rights, obligations and interests to form a new enterprise and at the same time the termination of the existence of the consolidating enterprises.
(c) Acquisition of an enterprise means the purchase by one enterprise of all or part of the assets of another enterprise sufficient to control or govern the activities of one or all of the businesses of the acquired enterprise. Controlling or governing all or one of the businesses of another enterprise means an enterprise (controlling enterprise) obtains ownership of the assets of another enterprise (controlled enterprise) sufficient to give the controlling enterprise 50% of the voting rights at the general meeting of shareholders, the board of management or other level sufficient according to law or the charter of the controlled enterprise to enable the controlling enterprise to govern the financial policies and operations of the controlled enterprise aimed at receiving economic benefit from the business operations of the controlled enterprise.
(d) Joint venture between enterprises means two or more enterprises together contribute a portion of their lawful assets, rights, obligations and interests to form a new enterprise.
Article 20.1 of the Competition Law provides that if the parties to a merger have a combined market share in a relevant market from 30% to up to 50% then the parties must notify the Vietnam Competition Authority of the enterprise acquisition before completing the merger unless the parties to the merger still remain a small and medium enterprise after the merger. A small and medium enterprise under Vietnamese law is subject to different criteria based on its business lines. But in general, a small and medium enterprise should not have more than 300 employees and a charter capital of more than VND 100 billion (about US$ 4.8 million). An economic concentration with a combined market share of more than 50% is prohibited unless an exemption is granted.
The State Bank of Vietnam (SBV) officially issued Circular 38/2026/TT-NHNN dated 31 July 2026 on foreign exchange management for foreign investment activities in Vietnam (Circular 38/2026). Effective from 18 August 2026, Circular 38/2026 replaces Circular 06/2019/TT-NHNN (Circular 06/2019) as amended by Circular 03/2025/TT-NHNN (Circular 03/2025), which has governed the direct investment capital account (DICA) regime since 2019. Circular 38/2026 also terminates Articles 11.3 and 11.4 of Circular 03/2025 on opening and use of VND-denominated accounts for conducting foreign indirect investment in Vietnam and amends Circular 16/2014/TT-NHNN on the use of foreign currency and Vietnamese dong accounts of residents and non-residents.
A typical share sale agreement (SPA) takes effect on signing. Closing, when the buyer and the seller exchange money and title to the shares, usually comes later, once conditions have been met. One might expect tax on the sale to be imposed when the shares are sold, that is, at closing. But where a foreign enterprise with no permanent establishment (Foreign Seller) in Vietnam sells shares in an unlisted Vietnamese company to a resident buyer, Article 5.2(a) of Circular 20/2026 provides that revenue is taxed when the initial capital-transfer contract takes effect. On the face of that Article, the SPA can be that contract, and signing can be when it takes effect. The fact that closing has not yet occurred might not, by itself, defer the tax. Until Circular 20/2026, that was not so.
Similar to the Enterprise Law 2005 and the Enterprise Law 2014, the Enterprise Law 2020 is silent on whether founding shareholders may hold voting preference shares newly issued after the issuance date of the enterprise registration certificate (ERC), and only provides at Article 116.1 that the voting preference of founding shareholders is effective for three years from that date. This blog will examine different views on this issue.
On the one hand, one may support the view that founding shareholders are entitled to hold voting preference shares issued after ERC issuance date because:
Based on Resolution No. 206/2025/QH15 of the National Assembly on special mechanisms to address difficulties and obstacles arising from legal regulations, the Government has issued several Resolutions on administrative procedure reduction (such as Resolution 66.16/2026/NQ-CP, Resolution 66.18/2026/NQ-CP, etc.). Most of these provisions remain effective until 28 February 2027. If new provisions covering the same subject matter are promulgated to replace them during this period, the relevant provisions of these Resolutions will automatically cease to be effective.
On 16 March 2026, the Ministry of Public Security (MPS) issued the draft decree on administrative sanctions in the fields of cybersecurity and personal data protection (the Draft Decree) for public consultation. It is the first step to put concrete penalties behind the PDPL 2025, which took effect on 1 January 2026 but left the enforcement details to the Government. The Draft covers a wide range of sectors, such as cybersecurity, personal data, AI, telecommunications, and digital signatures. This post focuses on the personal data provisions (Articles 57 to 69 of the Draft Decree), which raise potential concerns for businesses.
On 5 June 2026, the Government issued Decree 200 on private placement and trading of corporate bonds on domestic market and offering of corporate bonds on international market (Decree 200/2026). Decree 200/2026 will replace Decree 153/2020 (as amended) on the same subject. We have discussed certain contents of Decree 200/2026 in New Decree on private bonds (Part 1) — Vietnam Business Law.
The Government officially issued Decree 102/2026/NĐ-CP (Decree 102/2026), which introduces critical amendments and supplements to Decree 75/2019/NĐ-CP (Decree 75/2019) regarding administrative penalties for violations in the competition sector. Effective from 20 May 2026, Decree 102/2026 provides clearer enforcement guidelines and adjusts penalty frameworks, particularly for economic concentrations.
Below is a summary of the key changes introduced by Decree 102 that will directly affect M&A transactions subject to merger control (economic concentration notification) requirements in Vietnam.
In March 2026, Vietnam’s Ministry of Finance (MOF) released a draft decree (Draft Decree) implementing the Law on Personal Income Tax 2025 (PIT Law 2025) for public consultation. One proposal drew strong feedback from businesses and investors: a change to how individuals are taxed on the transfer of shares in non-public/unlisted joint-stock companies (JSCs). Following the consultation, the MOF now appears poised to step back from that change – welcome news for investors and companies engaged in M&A and private share transactions.
On 5 June 2026, the Government issued Decree 200 on private placement and trading of corporate bonds on domestic market and offering of corporate bonds on international market (Decree 200/2026). Decree 200/2026 will replace Decree 153/2020 on the same subject. In the past, Decree 153/2020 has been amended by Decree 65/2022 and Decree 8/2023. Decree 200/2026 introduces more conditions for private bond issuance.
5x debt/equity ratio
1.1. Decree 200/2026 reflects the 5x debt/equity requirement established under the 2025 amendment to the Enterprise Law. In particular, the debt of a bond issuer (including the value of the bonds to be issued) must not exceed 5 times of the equity of such issuer as recorded in the audited financial statements of the year preceding the issuance.
