MID-MARKET M&A ANALYSIS AND STRATEGY IN VIETNAM

Introduction

The mid‑market mergers and acquisitions (M&A) sector in Vietnam is undergoing a significant transformation, emerging as a key channel for corporate restructuring, technology transfer, and scale expansion. Shifts in the business environment, regulatory policy, and investor expectations have created new opportunities alongside fresh risks, forcing buyers and sellers to recalibrate transaction strategies and applicable legal frameworks.

This article aims to provide a comprehensive overview of the mid‑market landscape, analyze typical legal risks, and propose a practical legal playbook to optimize deal structure and protect parties’ interests. The analysis draws on recent market trends, relevant laws, and practical lessons from representative transactions to give investors, legal advisors, and company executives a solid basis for informed decision‑making in this segment.

The article proceeds to outline market context, identify principal legal risks, present due‑diligence and valuation approaches, and offer a toolkit of strategic measures designed to mitigate risk and enhance deal value in mid‑market M&A transactions.

Part I Market Context and Characteristics of Mid-Market M&A

1.1 Definition and Positioning of Mid-Market M&A in Vietnam

Mergers and acquisitions (M&A) activity in Vietnam has remained dynamic despite a slowdown in global M&A markets.

In the field of M&A, deals are often classified by transaction value to assess their scale and impact.

• Small-cap deals: These typically have a value of less than 100 million USD.
• Mid-market deals: This is the broadest segment and attracts significant interest from many investors. Transaction values usually range from 100 million USD to 500 million USD. Deals in this range are often carried out by medium-sized to large companies, Private Equity firms, or strategic investors.
• Large-cap and Mega-deals: These have transaction values of 500 million USD or more, sometimes reaching billions of USD. These deals typically involve multinational corporations or publicly listed companies with large market capitalizations.

In Vietnam, the mid-market M&A threshold may be considered slightly lower than the global average. Transaction values ranging from 50 million USD to 200 million USD are often considered active mid-market deals.

Mid-market deals usually account for a large proportion of the total number of transactions, even though their cumulative value is not as high as that of mega-deals. This is a crucial segment that reflects the development of the economy, with the participation of small and medium-sized companies seeking opportunities for market expansion, rapid growth, or restructuring.

Vietnam continues to attract investors because of an open economy, a high working-age population share, and investor-friendly policies. A key trend in H1 2025 is a marked shift toward mid- and small-cap M&A, reflected in falling average deal sizes. The average deal size decreased from USD 52.3 million in 2023 to USD 41.5 million in 2024, and fell further to USD 23.5 million in Q1 2025, indicating fewer blockbuster deals and a stronger focus on local, strategic investments. This average sits within the conventional mid-market range (typically USD 10 million to under USD 100 million), showing investors target high-growth firms, often private or family-owned businesses seeking expansion or restructuring capital. The drop to USD 23.5 million has important legal implications relative to the Economic Concentration Notification (ECN) threshold under Competition Law. The turnover-triggering threshold for ECN is VND 1,000 billion (approximately USD 40 million). Even with lower average deal sizes, many mid-market transactions may still trigger ECN via alternative tests such as combined total assets or turnover, meaning a large portion of mid-market M&A in Vietnam may require ECN filings, increasing antitrust compliance burdens and lengthening deal timelines.

1.2 Market Trend Analysis 2024–2025: Drivers and Leading Sectors

Vietnam’s M&A market is expected to continue long-term growth, supported by legal reforms that improve transparency and investor confidence, such as the 2024 Land Law and the Digital Technology Industry Law enacted in June 2025. Leading sectors and shifting focus: In H1 2025 real estate rebounded strongly, with total transaction value around USD 1.8 billion (approximately 30% YoY growth). Real estate accounted for 44% of total deal value in Q1 2025, concentrated in industrial parks, residential, and resort tourism. Besides real estate, retail, renewable energy, financial services, and technology continue to attract significant domestic and foreign capital, reflecting investor bets on Vietnam’s rising consumer class and young population, supported by GDP growth forecasts (estimated 5.8% for 2024). Strategic investors, notably from Japan, remain key drivers. Although total Japanese deal value in 2024 declined year-on-year, the number of transactions rose to 21 deals, underscoring a strategy of sustainable expansion via mid- and small-sized deals. Japanese investors are shifting strongly into healthcare services, advanced technology, retail, and medical supply chains. The capital shift materially changes legal risk profiles. In mid-market tech and healthcare deals, legal risk now centers on intangible assets (intellectual property), validity of critical contracts, and compliance with sector-specific licensing and conditional business requirements rather than complex land issues. Law firms must therefore restructure Legal Due Diligence to prioritize IP ownership checks and specialized licensing reviews because transaction failures can now stem from IP disputes or missing operating permits.

Practical Legal Priorities for Mid-Market M&A

• Legal Due Diligence (LDD): Prioritize IP audits, material contracts review, licensing, and regulatory compliance for sector-specific permits.
• Transaction structuring: Design structures that manage TTE risk, tax efficiency, and minority protection while preserving value.
• Antitrust compliance: Early assessment of TTE thresholds and alternative remedies to streamline notification and clearance.
• Risk mitigation: Use tailored warranties, indemnities, escrow mechanisms, and phased closings to allocate and limit post-closing exposure.
• Closing efficiency: Standardize documentation, create regulatory checklists, and engage local authorities early to shorten timelines.

Part II Legal Framework Analysis for M&A in Vietnam

2.1 Core Legal Pillars

2.1.1 Enterprise Law 2020 Structure and Internal Procedures

The Enterprise Law 2020 governs corporate internal affairs and prescribes the basic restructuring forms such as mergers, consolidations, business acquisitions, and changes in corporate type. The most common form in Vietnam is the share deal, where the buyer acquires shares from existing shareholders to become a new shareholder and obtain governance rights according to ownership percentage. The Enterprise Law 2020 sets out mandatory procedures for mergers, including approval by the General Meeting of Shareholders or members, creditor notification obligations, and registration of changes to the company registration with the competent authority.

2.1.2 Investment Law 2020 Foreign Investment Control Thresholds

The Investment Law 2020 regulates market access conditions and investment procedures for foreign investors. It provides clearer rules while changing a key control threshold. Under Article 23, an economic organization with foreign investment must follow foreign investor investment procedures when foreign ownership of charter capital reaches 50 percent or more. This threshold was reduced from 51 percent under the 2014 Investment Law, with significant effects on mid-market M&A strategies. If a foreign investor contributes capital or purchases shares with ownership at or below 50 percent and does not operate in a conditionally restricted sector, they only need to update member/shareholder information with the business registration authority rather than complete the foreign investment registration procedure. However, because mid-market transactions often aim for control (typically 50 percent plus one share), lowering the control threshold to 50 percent means many strategic deals now trigger the more complex and time-consuming foreign investment registration process, increasing administrative barriers for majority acquisitions.

2.2 Economic Concentration Control under Vietnam Competition Law

2.2.1 Notification Thresholds for Economic Concentration (Decree 35/2020/ND-CP)

Vietnamese competition law applies a pre-merger control regime to economic concentrations, including M&A, to assess and prevent transactions that may substantially lessen competition. Parties to a concentration must notify the Vietnam Competition Authority (VCA) when a transaction meets notification thresholds. Under Decree 35/2020/ND-CP, a concentration triggers notification if any of the following criteria is met: total assets in Vietnam of the parties reach VND 3,000 billion; combined turnover from sales or purchases in Vietnam of the parties reach VND 3,000 billion; transaction value of the concentration equals or exceeds VND 1,000 billion (approximately USD 40 million); or the combined market share of the parties in the relevant market is 20% or more. The transaction-value criterion of VND 1,000 billion is the most common trigger for mid-market M&A and requires most mid-market deals to undergo pre-merger competition review, increasing compliance costs and timelines.

2.2.2 VCA Enforcement Practice and the Gap between Rules and Reality

Although the 2018 Competition Law and Decree 35/2020/ND-CP improved the legal framework for economic concentrations, enforcement practice still presents challenges. The VCA may assess factors beyond formal organizational structures to determine whether an entity is genuinely independent or effectively controlled by another party, using qualitative indicators that fall outside rigid quantitative rules. This enforcement approach means the VCA can apply a combination of criteria to establish control. The gap between statutory thresholds and enforcement practice creates legal uncertainty, particularly for foreign investors with complex ownership arrangements. Legal advisers must therefore go beyond checking quantitative thresholds and analyze cross-shareholdings, minority veto rights, and contractual arrangements to assess whether a transaction could be deemed a concentration requiring notification. This increases the complexity of Competition Due Diligence.

2.3 Sector-Specific Legal Rules in M&A

2.3.1 Land Law and Project Transfer Barriers

Land law and related regulations are decisive in M&A transactions involving real estate or project transfers (asset deals). Conditions for transferring all or part of a land-use project are strict and often difficult to satisfy in mid-market M&A.
Key conditions include: approved investment policy for the project; approved detailed planning; completion of compensation and resettlement; no disputes over land-use rights; and absence of asset seizure. Authority to approve transfers typically rests with the provincial People’s Committee or an authorized agency.
Because these requirements are stringent—particularly the obligation to complete compensation—many mid-market targets that are still under development or facing land-related issues cannot meet them. This often forces investors to opt for share deals, thereby inheriting historical land-law risks of the target.

2.3.2 Tax Issues in M&A

Taxation is a critical factor in determining M&A structure. Income from capital transfers (transfer of capital contribution/shares) is subject to corporate income tax at a 20% rate.
A major current issue is personal income tax on capital transfer proceeds received by individuals, typically founders of mid-market enterprises. In practice, individual sellers often declare a low transfer price, reporting minimal or no profit to reduce tax liability. To address tax shortfalls and increase transparency, the Ministry of Finance has proposed applying a 1% tax rate on the total transfer value.
If adopted, this proposal would simplify tax calculation in M&A. However, taxing the gross transfer value rather than net profit could significantly raise the seller’s tax burden, forcing individual sellers to negotiate higher sale prices to preserve net after-tax proceeds, a factor that law firms must account for when advising on valuation and deal terms.

Part III Transaction Structure Choices and Practical Legal Constraints

3.1 Comparing Common Transaction Structures: Share Deal vs Asset Deal

• Decision drivers: Choice between a share deal and an asset deal depends on commercial objectives, licensing rules, ownership thresholds, tax considerations, and administrative procedures.
• Two common structures: Share Deal (acquisition of shares/equity) and Asset Deal (purchase of specific assets).

Comparative analysis of legal and tax aspects

Criterion	Share Deal	Asset Deal
Target	Purchase of shares/equity in the company	Purchase of specific assets (machinery; land; contracts; IP)
Scope of liabilities	Assumes all historical liabilities and risks of the Target (debts; tax; litigation)	Assumes only liabilities agreed in the SPA; historical risks remain with the Seller; generally safer
Legal procedures	Change of shareholders/charter capital; IFRC if foreign ownership thresholds are met; generally simpler at company level	Transfer of individual asset titles (land, vehicle registration, contracts) is more complex and time‑consuming
Key tax issue for Seller	Corporate income tax / personal income tax on capital gain (20% TNDN)	Corporate income tax on asset sale; possible VAT on transferred assets
Key tax issue for Buyer	No basis step‑up for asset depreciation	Basis step‑up advantage: depreciation calculated from purchase price

3.2 Tax and Liability Analysis of Transaction Structures

Buyers often prefer an Asset Deal when acquiring a distressed company or a target with potential legal issues. An Asset Deal lets the buyer select desired assets and avoid inheriting the seller’s historical liabilities or legacy tax debts, offering greater protection.

However, in Vietnam’s mid-market M&A context, balancing risk mitigation (Asset Deal) against administrative feasibility is challenging. Due to complex and time-consuming land-transfer procedures (see 2.3.1), Share Deals remain the most common structure, forcing buyers to accept historical legal risks.

When buyers must choose a Share Deal to overcome administrative barriers, the law firm’s role becomes critical. Lawyers must accurately quantify LDD-identified risks and negotiate robust contractual protections such as escrow arrangements and indemnities to shift financial burden for historical liabilities onto the seller rather than relying solely on the shareholder-change registration process.

Part III Practical Legal Challenges

3.3 Practical Legal Challenges

3.3.1 Cultural and Legal Barriers for Foreign Investors

Foreign investor legal risks are a leading cause of M&A failures. Conflicts often arise from differences between international practices and Vietnam’s sector-specific rules, such as foreign ownership limits or mandatory joint-venture requirements in certain industries (for example, advertising). When a foreign investor cannot hold 100% ownership or full control of the target due to organizational or operational constraints, post‑M&A integration and governance become major challenges.

3.3.2 Risk of Information Asymmetry from the Seller

Mid‑market transactions frequently involve private or family‑owned companies with weak governance and fragmented legal records. Legal Due Diligence (LDD) therefore depends heavily on documents and disclosures provided by the seller. The principal risk is undisclosed liabilities or transactions that the buyer cannot discover, leading to unexpected debts or legal exposure after closing. To mitigate this risk, law firms must coordinate closely with the buyer’s financial advisors and independent auditors to reconcile records and detect undisclosed or irregular transactions.

3.3.3 Compliance Challenges with Specialized Laws

LDD commonly uncovers numerous compliance issues in mid‑market targets that can be costly to remediate. Typical findings include non‑compliance with land regulations (unsettled financial obligations after zoning adjustments), construction and environmental rules, and especially labor and social insurance (e.g., missing employee registers, unpaid social insurance, or labor contract violations). Such breaches are subject to administrative fines and retroactive claims that impose financial burdens on the buyer post‑acquisition. Law firms should advise buyers to require seller remediation of these compliance defects as a Condition Precedent (CP) to closing.

Part IV Legal Risk Mitigation Strategy and Expert Solutions

 

4.1 Comprehensive Legal Due Diligence Strategy

4.1.1 LDD Scope Focused for Mid-Market Deals

LDD must assess and verify financial, legal, and operational information of the target company with emphasis on the following legal areas:

• Investment and Licensing : Verify compliance of investment documentation, with special attention to foreign investor registration (IFRC) requirements and conditionally restricted business sectors. Assess procedural risks the buyer may inherit from the target’s investment status.

• Land and Construction: Conduct a detailed review of land‑use rights and planning documentation. Evaluate whether zoning or planning adjustments could trigger land price revaluation or additional state financial obligations.

• Labor and Social Insurance: Scrutinize employment records, labor contracts, and social insurance liabilities. Identify potential retroactive contributions or penalties that could impose post‑closing costs on the buyer.

• Intellectual Property (IP): Verify registration status and legal ownership of trademarks, patents, and copyrights, which are core assets in technology and service transactions.

4.1.2 Using LDD Findings to Adjust Purchase Price and Set Conditions Precedent (CPs)

LDD results enable the buyer to quantify legal risks and convert material issues into deal mechanics: price adjustments and Conditions Precedent (CPs) that the seller must satisfy or warrant in the transaction documents. Serious legal defects should not only justify a purchase price reduction but must also be transformed into CPs. Counsel should advise the buyer to require remediation of compliance issues (for example, completion of outstanding land tax obligations or establishment of employee registers) as CPs that must be fulfilled before the buyer releases payment.

4.2 SPA Drafting Techniques for Buyer Protection

4.2.1 Optimizing Representations and Warranties (R&W)

Representations and warranties (R&W) are common‑law constructs without a specific statutory framework in Vietnam. To ensure enforceability and effective remedies, local counsel must tailor (localize) R&W clauses. The SPA should be drafted so R&W operate either as independent obligations of the warrantor or as part of the description of the quality and attributes of the shares/assets sold. This approach enables application of Vietnamese civil and commercial remedies for breaches or non‑conforming deliverables. Clearly define liability caps and baskets to limit exposure while preserving meaningful recovery for the buyer.

4.2.2 Establishing Indemnity Mechanisms and Liability Limits

Indemnities are essential to protect the buyer against losses arising from identified historical liabilities (for example, tax assessments or administrative fines). Counsel must draft indemnity provisions with clear scope and survival periods and structure them as agreed loss‑recovery mechanisms consistent with Vietnamese civil and commercial law. Indemnity clauses should specify triggering events, calculation methods for losses, procedures for claims, and any carve‑outs or limitations, so the buyer can enforce recovery without conflicting with fundamental legal principles on damages.

---

4.3 Managing Payments and Post-Closing Risks

4.3.1 Role of Escrow Accounts and Purchase Price Holdbacks

Escrow accounts and purchase price holdbacks are essential protections for buyers in mid‑market transactions due to limited legal and financial transparency of targets.
A portion of the purchase price (typically 5%–15%) is held in an intermediary escrow account for a defined period (commonly 12–24 months).
Escrow funds are used to satisfy indemnity claims arising after closing, particularly undisclosed tax liabilities or social insurance and labor compliance breaches.
Counsel must draft clear, legally binding escrow release conditions and procedures, turning escrow into an effective financial risk‑transfer tool for the buyer.

Part V Case Study and Practical Illustration

5.1 Healthcare Sector M&A Example: Japanese Investor Strategy

Elan’s acquisition of 51% of TMC Vietnam illustrates Japanese strategic investors’ shift into healthcare services.
This transaction demonstrates foreign investors’ interest in long‑term value from healthcare support services and private hospitals in Vietnam.
From a legal perspective, the 51% stake exceeded the 50% foreign ownership threshold and triggered foreign investment registration (IFRC) under the Investment Law 2020.
Advisors must (1) ensure compliance with tightly regulated healthcare business conditions and (2) perform specialized LDD to verify the validity and continuous maintenance of sector‑specific operating licenses, as these are core risks to post‑transaction operations.

5.2 Real Estate-Asset M&A Example: Zoning Adjustments and Additional Financial Obligations

In real estate project M&A, a common legal risk is additional land-related financial obligations. Although the seller may present documents showing initial land payments have been completed, subsequent zoning adjustments can prompt competent state authorities to revalue the project land. As a result, the investor (i.e., the buyer after completion) may be required to make substantial additional payments to the State.

Legal application analysis: Legal counsel must perform detailed Legal Due Diligence (LDD) to identify the risk of zoning change. If this risk is identified, counsel should quantify the potential additional financial obligation. That estimated reserve must then be incorporated into the seller’s representations and warranties and secured via an escrow mechanism to withhold a portion of the purchase price corresponding to the potential obligation, thereby protecting the buyer’s financial interest against historic legal risk.

Conclusion and Final Recommendations

The mid-market M&A sector in Vietnam is a significant growth driver, shown by decreasing average deal size alongside continued deal activity and a shift toward higher-value service sectors such as healthcare and technology. This segment faces distinctive legal and administrative challenges that require professional risk management strategies.
Core issues include a multi-layered legal framework that raises compliance costs—notably pre‑merger economic concentration notification (TTE) and the 50%+ foreign investment control threshold (IFRC)—and weak historical transparency and compliance of target companies, especially in land, tax, and labor matters.

Key Legal Advisory Imperatives

Effective legal advisory in M&A requires a multifaceted approach to mitigate risks and ensure transaction success. First, comprehensive Legal Due Diligence (LDD) must go beyond financial statements and tangible assets. It should rigorously assess sector-specific regulatory compliance, intellectual property ownership, and potential liabilities such as retroactive tax and labor-related administrative claims. The insights from LDD should directly inform the drafting of Conditions Precedent, safeguarding parties before closing.

Second, contract drafting must be meticulously localized to Vietnamese law. Representations, Warranties, and Indemnities should be precisely customized to establish enforceable obligations and provide effective remedies in case of breach. This tailored approach ensures contracts are robust and legally binding within the local jurisdiction.

Third, managing financial exposure through escrow arrangements is critical, especially in Share Deals that may involve legacy risks. Utilizing escrow or holdback mechanisms allows parties to reserve funds specifically for addressing identified historical liabilities, protecting the buyer from unforeseen financial burdens.

Together, these key legal imperatives form the foundation of a sound M&A legal strategy in Vietnam, balancing thorough risk assessment with enforceable protections to facilitate smooth and secure transactions.

Our Recommendations

To support the growth of mid-market M&A, enhancing regulatory clarity and simplifying procedures is essential. The Vietnam Competition Authority should offer clearer guidance on economic concentration assessments to reduce uncertainty for investors. This clarity enables better risk evaluation and smoother deal execution.

In addition, streamlining asset-transfer procedures for real estate projects is critical. Simplifying approvals for project transfers and land-use rights, especially for foreign investors, allows greater flexibility in deal structuring and better risk allocation. These improvements attract higher-quality investment, particularly in real estate, hospitality, and infrastructure sectors.

Such reforms not only ease transactions but also boost Vietnam’s position as a competitive regional investment destination, fostering sustainable growth in the M&A market.
