Enterprise Merger in Vietnam: Legal Guidance & Integration Strategy for FDI/Japanese Enterprises

After receiving a new Enterprise Registration Certificate from the competent authority, many executives of Japanese FDI enterprises in Vietnam realize that the real challenge has only just begun. The success of an M&A transaction does not end with completing legal procedures; it also depends on the ability to seamlessly integrate corporate culture, people, and operational systems. In this article, KMC provides a comprehensive roadmap covering everything from distinguishing key concepts and implementing proper legal procedures to developing a detailed plan for the highly challenging “post-merger integration” phase.

Distinguishing Merger and Consolidation

Understanding the Concepts Correctly Under Vietnamese Law

Pursuant to the Law on Enterprises 2020, these two forms are clearly defined as follows:

Enterprise Consolidation (Article 200): Refers to the process where two or more companies combine to establish an entirely new company, while simultaneously terminating the existence of all existing companies. This can be simply illustrated as follows:
Company A + Company B = New Company C

Enterprise Merger (Article 201): Refers to the process where one or more companies transfer all assets, rights, and obligations to another existing company, and the transferring companies cease operations. The formula in this case is:
Company A + Company B = Company B remains (expanded).

Illustrative Example

Assume that XYZ Japan Group currently has two subsidiaries in Vietnam:

• XYZ Vietnam Manufacturing Co., Ltd. (with a factory and manufacturing license)
• XYZ Vietnam Trading Co., Ltd. (with a customer network and distribution license)

MERGER Scenario: The Trading Company is merged into the Manufacturing Company.

Result: XYZ Vietnam Manufacturing Co., Ltd. continues its business operations and inherits the entire customer network and distribution license of the Trading Company. The Trading Company ceases its operations.

CONSOLIDATION Scenario: The two companies are consolidated.

Result: Both the Manufacturing Company and the Trading Company cease their operations. A new company, New XYZ Vietnam Co., Ltd., is established and inherits all assets and rights of both companies.

Legal Merger Process for Japanese FDI Enterprises

The enterprise merger process in Vietnam is clearly regulated under the Law on Enterprises 2020. However, for foreign-invested enterprises (FDIs), such as Japanese enterprises, this process not only requires compliance with the Law on Enterprises but must also satisfy specific requirements under the Law on Investment and regulations relating to taxation and labor matters.

Step 1: Prepare the Merger Plan and Review Prerequisite Conditions

The parties jointly prepare a detailed merger plan. This plan must include all information required under Article 201 of the Law on Enterprises 2020, such as company names and addresses; value of assets, rights, and obligations to be transferred; and implementation timelines and conditions.

Note: The merger plan must clearly specify arrangements and restructuring measures for employees of the merged company. The company should establish a clear workforce strategy to maintain employee morale and avoid mass resignations of key personnel.

For FDI enterprises, several specific conditions should also be reviewed:

Competition Requirements

The enterprise must determine whether the transaction falls under cases requiring notification to or approval from the National Competition Commission under the Competition Law 2018.

Foreign Ownership Ratio

The enterprise should also determine whether the merger would change ownership ratios and exceed foreign ownership limitations applicable to the enterprise’s business sectors under the Law on Investment 2020.

Step 2: Approve the Resolution and Execute the Merger Agreement

After reaching agreement on the merger plan, two important internal legal documents must be completed.

Approval of the Resolution

The Members’ Council (for limited liability companies) or the General Meeting of Shareholders (for joint stock companies) of each relevant company must hold meetings and approve the merger plan.

Note:

The voting approval threshold is generally very high, typically requiring at least 75% of contributed capital or voting shares. This requires substantial consensus from shareholders and major investors.

Execution of the Merger Agreement

The merger agreement must provide detailed provisions regarding asset conversion arrangements, shares, capital contribution portions, and particularly the labor utilization plan based on the approved proposal. In addition, it must be executed by the parties and notarized or certified.

Note for FDI Enterprises:

During the asset valuation stage for transfer purposes, FDI enterprises should pay close attention to transfer pricing regulations. Valuation that does not reflect market value may result in tax adjustment risks imposed by Vietnamese tax authorities.

Step 3: Prepare a Complete Legal Dossier (Detailed Checklist)

You are required to prepare and submit this dossier to the Business Registration Authority. Below is a basic checklist for reference:

Note: This is a basic checklist. Depending on the business sector and specific circumstances, FDI enterprises may be required to provide additional documents and supporting papers.

Step 4: Submit the Dossier and Follow Up with the Business Registration Office (BRO)

• Submission location: The Business Registration Office under the Department of Finance where the receiving company is headquartered.
• Submission method: The dossier may be submitted directly, by post, or online through the National Enterprise Registration Portal.
• Processing timeline: In accordance with regulations, the Business Registration Office is responsible for updating the enterprise’s legal status and issuing a new certificate (if applicable) within three (03) working days from the date of receipt of a complete and valid dossier.

Step 5: Complete Legal Procedures and Amend the Investment Registration Certificate

After obtaining the new Enterprise Registration Certificate for the receiving company (if there are changes to registered information), the enterprise should proceed with amendments to the Investment Registration Certificate (IRC).

Why is this necessary? A merger will inevitably change the investor structure, investment capital, and project implementation location compared to the information originally registered under the initial IRC.

The enterprise must carry out IRC amendment procedures with the Investment Registration Authority (typically the provincial Department of Finance or the Industrial Zone Management Board) to accurately reflect the enterprise’s new legal status. Failure to do so may result in administrative penalties and create difficulties in future procedures relating to taxation and import-export activities.

For certain regulated industries such as banking, insurance, and pharmaceuticals, enterprises may also be required to notify or obtain approval from specialized regulatory authorities such as the State Bank of Vietnam, the Ministry of Health, or other competent authorities.

Post-Merger Phase: Turning “Two into One” in Practice

Corporate Culture Integration and Internal Communication

Differences between Japan’s structured management culture and the flexibility and autonomy commonly seen in Vietnamese enterprises can create underlying friction. Therefore, it is essential to understand these core differences to help employees effectively integrate the two corporate cultures.

Specifically, the Japanese management style emphasizes Horenso (Report – Inform – Consult), the Nemawashi process (informal pre-discussion to build consensus), respect for clearly defined hierarchy, and collective decision-making. In contrast, the Vietnamese management style tends to be more flexible, values adaptability, favors faster decision-making, and often grants greater individual autonomy with more direct communication practices. Rather than imposing one company’s culture on the other, enterprises should identify and build upon core values derived from the strengths of both sides. Organizing seminars, workshops, and cross-cultural exchange sessions can also help both teams better understand each other.

In addition, talented employees from the merged company may easily feel uncertain about their future and choose to leave. Therefore, enterprises should establish clear recognition and compensation policies, along with fair career development opportunities within the new organization, to avoid a “brain drain” situation.

Integration of Management Systems and Technology

The two companies may currently be using different accounting software, different CRM (Customer Relationship Management) systems, and entirely separate approval processes. A lack of integration may result in operational disruptions, misunderstandings, and reduced productivity.

Therefore, enterprises should establish a comprehensive IT Integration Plan, including:

Current System Assessment: Review all information technology systems, including accounting software, ERP systems, HRM systems, email platforms, servers, and other operational infrastructure.

Selection of a Unified System: Determine whether to adopt one party’s existing system or invest in a completely new integrated platform.

Data Migration and Integration: This is a technically complex process requiring a clear roadmap to ensure that critical customer, financial, and human resource data is not lost.

Employees from the merged company should also receive structured retraining to effectively use the new systems. Such support from the company can help minimize operational challenges and enable employees to integrate more quickly into the new working environment.

Review and Consolidation of Contracts

The receiving company will inherit all contracts with partners, suppliers, and customers of the merged company. This creates both opportunities and potential risks; therefore, a comprehensive contract review should be conducted:

Identify overlapping contracts. For example, both former companies may have procurement agreements for raw materials with the same supplier. This creates a valuable opportunity to renegotiate more favorable pricing based on larger purchasing volumes.

Assess obligations and risks by reviewing provisions relating to penalties, contract termination, and confidentiality obligations.

Written notification must be sent to all business partners regarding the change of the contracting legal entity (from the former company to the post-merger company). This helps ensure legal validity and minimizes future disputes.

Human Resource Management After the Merger

Human resources are the company’s most valuable asset and also the most sensitive issue during post-merger integration. An unclear HR policy can undermine all integration efforts. Therefore, enterprises should:

• Standardize compensation and benefits policies. The two companies may have different compensation structures, employee benefits, and welfare policies (insurance, leave entitlements, etc.). A unified and equitable policy with a clear implementation roadmap should be established to avoid employee dissatisfaction and internal comparisons.
• Establish clear and objective criteria (based on competencies, performance, and experience) for restructuring overlapping leadership and management positions after the merger. Priority should be given to solutions such as internal transfers, retraining programs, and career transition support rather than direct termination.
• Reach agreements with employees regarding all changes, including job positions, work locations, and compensation arrangements in compliance with the provisions of the Vietnamese Labor Code. Unilateral changes may result in collective labor disputes, potentially causing serious reputational damage and operational disruption for the newly merged enterprise.

Frequently Asked Questions on Enterprise Mergers for FDI/Japanese Enterprises

How Long Does the Merger Process Take?

The completion timeline can vary significantly depending on the complexity of the transaction. It can generally be divided into two phases:

Preparation and Internal Negotiation Phase (1–3 months)

This phase includes negotiation of merger terms, due diligence procedures, approval of resolutions, and execution of agreements. This is typically the most time-consuming phase.

Official Legal Procedure Phase (1–2 months)

Procedures at the Business Registration Office: 3–5 working days after submission of a complete and valid dossier.

Procedures for amendment of the Investment Registration Certificate (IRC): 15–30 working days and potentially longer if the business sector requires consultation or approval from relevant ministries or authorities.

The total practical timeline for an average merger transaction generally ranges from 3–6 months.

How Can Language Discrepancies in Documents and Agreements Be Addressed?

As a general principle, the Vietnamese version serves as the official legally binding version when documents are submitted to state authorities or disputes are resolved in Vietnam. To address language discrepancies in merger documentation and agreements, enterprises should prepare bilingual versions of the Charter in Vietnamese–English or Vietnamese–Japanese (for Japanese FDI enterprises). The language clause should clearly state: “In the event of discrepancies, the Vietnamese version shall prevail.”

Enterprises should engage a Vietnamese legal consulting firm or lawyer experienced in working with Japanese clients to draft, review, and proofread documentation. This helps ensure both linguistic accuracy and legal precision.

What Legal Costs Are Typically Involved in a Merger Transaction?

Legal costs are not fixed and depend on the transaction size and level of complexity. Main cost items generally include:

• Due Diligence Fees: Costs for lawyers, independent auditors, and reviews of the target company’s legal and financial status.
• Legal Advisory and Drafting Fees: Fees paid to consultants for drafting agreements, preparing merger plans, and supporting the entire process.
• Government Fees: Fees for amendments to enterprise registration information and adjustment of the Investment Registration Certificate.
• Notarization and Certification Fees: Required for merger agreements and various supporting documents.
• Certified Translation Fees: Applicable to bilingual documentation.
• Other Potential Costs: Such as tax advisory costs relating to asset transfers, partner notification expenses, and labor consulting costs.
• To better control budgets, enterprises should request a detailed cost estimate by work category from consulting firms at the outset of the transaction.

In summary, successfully combining two companies requires more than simply completing legal procedures. Enterprises must also address challenges relating to corporate culture, human resources, and inherited contracts from the merged company. These considerations demonstrate that enterprise mergers are highly complex strategic projects.
