Dear Clients and Partners,

The landscape for Mergers and Acquisitions (M&A) in Vietnam has undergone a significant transformation as we move through 2026. While the market remains one of the most vibrant in Southeast Asia, the regulatory environment has become increasingly sophisticated and, at times, demanding. For foreign investors and domestic enterprises alike, navigating this terrain requires more than just a keen eye for business value; it demands a rigorous understanding of the evolving legal framework.

At BLaw Vietnam, we have observed that even the most seasoned investors can encounter significant delays or financial losses due to preventable oversights. This article aims to provide you with expert M&A Vietnam legal advice to help you identify and mitigate the most common pitfalls in today's market.

1. Navigating Overlapping Regulations and Realistic Timelines

One of the most persistent challenges in the Vietnamese M&A sector is the interplay between various laws, specifically the Law on Investment and the Law on Enterprise. Despite efforts to harmonize these statutes, inconsistencies remain, particularly concerning approval procedures for multi-sectoral businesses.

In 2026, the scrutiny from the Department of Planning and Investment (DPI) and relevant ministries has intensified. It is no longer sufficient to assume a standard 3-month closing window. Depending on the complexity of the target’s operations: especially if they involve sensitive sectors like energy, telecommunications, or logistics: the approval process can realistically extend from 6 to 12 months.

Actionable Advice:

• Engage Early: Do not wait until the Term Sheet is signed to consult with legal counsel. Preliminary assessments of the regulatory requirements can save months of backtracking.
• Build-in Buffers: Ensure your Sale and Purchase Agreement (SPA) includes realistic Long Stop Dates that account for administrative "quiet periods" or requests for additional documentation from authorities.

2. The Trap of Foreign Ownership Thresholds

A common pitfall involves the "reclassification" of an entity when foreign ownership crosses critical thresholds. In Vietnam, a company is often treated differently depending on whether it is under or over a 50% foreign ownership mark. Crossing from 49% to 51% is not just a change in equity; it is a change in the legal status of the company, often shifting it from a "domestic" entity to a "foreign-invested" entity.

This shift can trigger a cascade of new compliance requirements, including more stringent reporting and restrictions on certain business lines that were previously open to the company as a domestic player. Furthermore, the 2026 regulatory environment has placed a spotlight on "sham" transactions: structures designed solely to circumvent foreign investment caps. Authorities now have broader powers to challenge and even terminate operations if they suspect a transaction is intended to bypass the spirit of the Law on Investment.

Actionable Advice:

• Threshold Planning: If your business strategy permits, consider structuring the deal to remain below sensitive thresholds, or alternatively, prepare for a full transition to foreign-invested status from Day 1.
• Transparency is Key: Avoid overly complex "nominee" structures. Instead, seek legitimate tax planning and optimization services to ensure your investment is compliant and sustainable.

3. Due Diligence Red Flags: Land and Litigation

In Vietnam, due diligence must go beyond financial audits. Two areas consistently present the highest risk: Land-Use Rights (LUR) and undisclosed litigation.

The Complexity of Land-Use Rights

Ownership of land in Vietnam is a unique legal concept where the State owns the land, and entities hold "use rights." In many M&A deals, the target company may have irregularities in how these rights were obtained or registered. If the LUR is not properly titled or if the land-use purpose does not match the company’s actual operations, the transaction could be voided or the assets seized post-acquisition.

The Lack of Centralized Litigation Databases

Unlike many Western jurisdictions, Vietnam does not have a comprehensive, centralized database for pending litigation. Relying solely on a target company’s representation that "no litigation is pending" is a high-risk strategy.

Actionable Advice:

• Physical Verification: Conduct on-the-ground verification of land assets and interview local authorities to confirm the status of LURs.
• Enhanced Representations: Since you cannot verify litigation through a single database, your SPA must include robust indemnity clauses and specific warranties regarding government investigations and labor disputes.

4. Tax Optimization and Transaction Structuring

When approaching an M&A deal, the choice between a share acquisition and an asset acquisition carries heavy tax implications. This is where tax optimization Vietnam becomes a critical component of the deal value.

• Share Transfers: These are generally more straightforward in terms of continuity, as the buyer inherits all licenses. However, you also inherit all historical tax liabilities.
• Asset Transfers: These allow you to "cherry-pick" assets and leave behind historical liabilities. However, asset transfers often trigger Value Added Tax (VAT) and require the cumbersome process of re-applying for operational licenses and permits.

In the 2026 landscape, tax authorities are more efficient at tracking capital gains from offshore transfers involving Vietnamese assets. Ignoring these obligations can lead to severe penalties and reputational damage.

Actionable Advice:

• Pre-Deal Audit: Conduct a thorough tax planning review of the target to identify hidden liabilities.
• Structure for Efficiency: Work with specialists who understand how to declare tax to maximize profits while remaining strictly within the legal framework.

5. The Human Element: Employment Law Hurdles

A frequent oversight in M&A is the assumption that employees automatically transfer with the business. Under Vietnamese labor law, particularly with the 2026 updates, employment contracts do not automatically move to the buyer in an asset deal. Employees must voluntarily terminate their existing contracts and sign new ones with the acquiring entity.

Even in share deals, where the employer remains the same legal entity, a change in ownership can lead to labor unrest if not managed transparently. The costs associated with severance pay, social insurance arrears, and potential labor strikes can quickly erode the projected synergies of a merger.

Actionable Advice:

• Labor Due Diligence: Review all employment contracts, internal labor rules, and social insurance payment records.
• Communication Strategy: Develop a clear post-merger integration plan that addresses employee concerns early to prevent talent drain and legal disputes.

6. Post-Merger Compliance and Integration

The work does not end at the "Closing." In fact, many pitfalls emerge in the first 100 days post-deal. New foreign-owned entities are subject to specific reporting requirements that domestic companies are not. Failure to update investment certificates, business registration certificates, or sub-licenses can lead to the suspension of operations.

Furthermore, if the target company was involved in any debt recovery issues, these must be handled swiftly to avoid disrupting cash flow. BLaw Vietnam has specialized experience in this area, often working with partners to streamline debt recovery services for our clients.

Actionable Advice:

• Compliance Calendar: Create a strict timeline for post-closing filings and license amendments.
• Operational Audit: Within the first month, perform a "health check" on all operating permits to ensure they reflect the new ownership structure and remain valid under current 2026 regulations.
