Structuring a Controlling Share Acquisition Deal: Mitigating Hostile Risks

Structuring a controlling share acquisition deal requires more than securing a majority ownership stake. Investors must carefully assess charter provisions, shareholder veto powers, tender offer obligations, and competition filing requirements to obtain effective control. Transaction documents, including the Share Transfer Agreement, Shareholders’ Agreement, closing conditions, escrow mechanisms, and governance arrangements, should be aligned with the Law on Enterprises and Businesses. For acquisitions involving hostile resistance or concentration concerns, Long Phan Consulting provides end-to-end legal structuring from due diligence through post-closing integration.

Identifying Hostile M&A Risks and Limitations of Control in Controlling Stake Acquisitions

A controlling stake acquisition extends far beyond simply increasing ownership percentages. The core objective is establishing actual management control over voting rights, executive personnel, and the business trajectory of the target company. Failing to audit the corporate charter, veto rights, and resolution approval mechanisms leaves the buyer holding a majority share while remaining entirely locked out of executive power.

The Legal Nature of Share Acquisitions Leading to Veto or Control Thresholds

A controlling stake acquisition fundamentally differs from standard financial investments. Foreign investors target the ultimate authority to dictate strategic business decisions, rather than merely seeking dividends or capital appreciation.

An acquiring enterprise establishes control when it secures over 50% of the charter capital or over 50% of the voting shares of the target company. Control also arises if the buyer acquires or utilizes over 50% of the target company’s assets across one or all business lines, pursuant to Points a and b, Clause 1, Article 2 of Decree No. 35/2020/ND-CP.

To accurately assess the transaction’s legal nature, investors must scrutinize these specific corporate rights:

• Economic rights to receive dividends and divestment value.
• Voting rights at the General Meeting of Shareholders (GMS) for ordinary resolutions.
• Veto rights over material resolutions if the charter mandates high voting thresholds.
• Authority to appoint or dismiss executive personnel and Legal Representatives.
• Power to determine business strategies, budgets, major assets, and critical transactions.

While the 2020 Enterprise Law permits share transfers, founding shareholder restrictions or the corporate charter may legally block these transactions. Consequently, the acquisition dossier must be structured as a comprehensive control transaction, not a singular share transfer agreement.

Defensive Barriers from the Corporate Charter and Critical Voting Thresholds

A critical vulnerability arises when buyers confuse share ownership with actual corporate control. The corporate charter or Shareholders’ Agreement (SHA) frequently enforces critical voting thresholds exceeding the buyer’s targeted ownership percentage.

An investor holding 51% of shares can pass ordinary resolutions. However, if the charter demands 65% or higher for material decisions, the buyer cannot unilaterally restructure the enterprise.

Evaluating these thresholds requires cross-referencing the charter, the Shareholder Register, and the existing governance framework. The 2020 Enterprise Law strictly governs shareholder rights, GMS authority, and corporate governance structures. Therefore, buyers must prioritize acquiring sufficient shares to control or veto decisions directly impacting personnel, assets, capital, and business strategy.

Assessing the Risk of Public Company Status Cancellation to Neutralize Defenses

Public company status enforces rigorous regulatory barriers regarding information disclosure, governance, and mandatory public tender offers. This status serves as a formidable defense layer for target companies facing hostile M&A risks lacking Board of Directors (BOD) approval.

A public company with unlisted or unregistered shares prior to the effective date of the 2019 Securities Law faces the cancellation of public company status if it fails to maintain 30 billion VND in charter capital and a minimum of 10% of shares held by at least 100 non-major investors. This framework is strictly governed by the 2019 Securities Law.

Evaluating this public status holds immense strategic value for structuring the transaction:

• If public status remains, the buyer must strictly navigate mandatory public tender offers and disclosure obligations.
• If the target lawfully loses its public status, the acquisition strategy pivots heavily toward the corporate charter, Shareholder Register, and SHA.
• If the cancellation is manipulated, the transaction risks severe disputes with minority shareholders or competent state authorities.

Investors must treat this assessment as a mandatory component of Legal Due Diligence (LDD). Executing share purchases or signing a Share Purchase Agreement (SPA) before clarifying public status guarantees severe compliance liabilities.

Structuring Controlling Stake Acquisitions to Prevent Governance Deadlocks

Transaction structure dictates post-closing control capabilities. An improperly designed controlling stake acquisition can trigger defensive reactions, inflate purchase prices, or leave the buyer without actual governance authority. Investors must select a structure based on the target company’s legal status, shareholder dispersion, and pre-clearance obligations. For public companies, the strategic focus is the mandatory public tender offer; for non-public companies, the focus shifts to the charter, Shareholder Register, and Right of First Refusal (ROFR).

Acquisition Strategies via Private Placement and Direct Purchases from Existing Shareholders

Three common structures include direct purchases from existing shareholders, private placements or capital increases, and multi-phased acquisitions. Each structure generates different consequences regarding control, cash flow, and minority shareholder reactions.

For non-public companies, the 2020 Enterprise Law governs share transfer rights, corporate charters, and internal mechanisms. Buyers must rigorously audit the Shareholder Register before selecting a structure, as ownership data forms the foundation for the entire closing process.

Mandatory Public Tender Offer Obligations for Public Companies and Exemptions

For public companies, the share acquisition structure must be controlled from the very first ownership threshold. If an organization, individual, and affiliated persons intend to purchase voting shares leading to direct or indirect ownership of 25% or more, the transaction may require a mandatory public tender offer, pursuant to Point a, Clause 1, Article 35 of the 2019 Securities Law.

Enterprises may structure an exemption if the transfer plan reaching the threshold is formally approved by the target company’s General Meeting of Shareholders (GMS). This exemption is recognized under Point a, Clause 2, Article 35 of the 2019 Securities Law.

The control protocol for mandatory public tender offers should follow this sequence:

• Verify public company status and the exact total number of voting shares.
• Calculate the consolidated ownership ratio of the buyer, affiliated persons, and coordinating parties.
• Determine whether the purchase triggers the 25% threshold or subsequent mandatory thresholds.
• Evaluate the strategic feasibility of securing GMS approval for a valid transfer plan.
• Prepare the information disclosure plan, transaction timing, and regulatory filing dossiers.

If a tender offer must be withdrawn, the State Securities Commission holds the authority to receive the report and issue a written approval, pursuant to Clause 3, Article 92 of Decree 155/2020/ND-CP. This contingency must be drafted into the Share Purchase Agreement (SPA) to prevent the buyer from being trapped in a commercially unviable transaction.

Auditing Market Access Barriers for Foreign-Invested Economic Organizations

Foreign investors cannot rely solely on ownership percentages to determine the share acquisition structure. Prior to signing the SPA, the buyer must audit business lines, market access conditions, and the legal status of land assets.

Share acquisitions by foreign investors must satisfy national defense and security conditions if the target economic organization holds land use rights in coastal, border, island regions, or areas impacting national defense and security, pursuant to Point c, Clause 2, Article 21 of the 2025 Investment Law.

Pre-transaction structuring audits must address the following points:

• Whether the target company operates in restricted or conditional market access sectors.
• Whether the post-transaction ownership ratio triggers mandatory share purchase registration procedures.
• Whether the target holds land use rights in coastal, border, island, or sensitive national security areas.
• Whether the buyer, as an existing foreign-invested economic organization, must comply with current investment conditions for the new transaction.

Decree 96/2026/ND-CP detailing and guiding the implementation of several articles of the Investment Law serves as the mandatory cross-reference when designing investment dossiers. Bypassing this regulatory layer guarantees the transaction will be blocked during registration or fail to complete the transfer of control.

Focus of the Corporate Legal Due Diligence Report to Mitigate Transaction Blocking Risks

The Corporate Legal Due Diligence (LDD) Report serves as the primary defense layer prior to signing the Share Purchase Agreement (SPA). The objective is not merely confirming assets, liabilities, and contracts, but uncovering mechanisms that could permanently block the buyer from closing. In transactions exhibiting hostile takeover risks, vulnerabilities typically reside within the corporate charter, Shareholder Register, preemptive rights, credit commitments, and pre-clearance competition obligations. Failing to neutralize these elements in advance ensures that while the purchase price is finalized, actual control remains blocked.

Identifying Transfer Restrictions and Right of First Refusal (ROFR)

Investors must audit the corporate charter, Shareholder Register, and existing Shareholders’ Agreements prior to negotiating the purchase price. This step determines whether the target shares are freely transferable or locked by a Right of First Refusal (ROFR). The 2020 Enterprise Law strictly places share transfer rights within the boundaries of the corporate charter and regulations applicable to founding shareholders. Consequently, controlling stake acquisitions must be verified against internal corporate records, rather than relying solely on the seller’s representations.

Urgent documentation requiring immediate LDD review includes:

• The corporate charter and its most recent amendments.
• The Shareholder Register, ownership data, and historical share transfers.
• Shareholders’ Agreements, ROFR clauses, and transfer restrictions.
• Non-compete commitments, restrictions on working with competitors, and confidentiality clauses.
• Credit agreements, guarantees, distribution contracts, and material client agreements.

Bypassing the ROFR empowers existing shareholders to formally oppose the transaction or petition to invalidate the share transfer. This direct risk severely delays closing and cripples the buyer’s negotiating leverage.

Evaluating Economic Concentration Notification Obligations and Revenue Penalty Risks

When a transaction enables the buyer to control or dominate another enterprise, it may be classified as an economic concentration. The paramount risk lies not within the SPA itself, but in executing closing without fulfilling pre-clearance obligations. Enterprises must self-assess their economic concentration notification obligations prior to executing the transaction. The statutory warning thresholds include total assets or total revenue in Vietnam of 3,000 billion VND or more, a transaction value of 1,000 billion VND or more, or a combined market share of 20% or more, pursuant to Points a, b, c, and d, Clause 1, Article 13 of Decree No. 35/2020/ND-CP.

The National Competition Commission (NCC) must issue the preliminary appraisal results within 30 days of receiving a complete and valid dossier, pursuant to Clause 1, Article 14 of Decree No. 35/2020/ND-CP. If an official appraisal is mandated, the timeline extends to 90 days from the preliminary result notification, extendable by up to 60 days, pursuant to Clause 1, Article 37 of the 2018 Competition Law.

The maximum administrative fine for violating economic concentration regulations is 5% of the violating enterprise’s total revenue in the relevant market, pursuant to Clause 2, Article 111 of the 2018 Competition Law. Beyond financial penalties, regulatory agencies hold the authority to compel the division, separation, or resale of portions or the entirety of contributed capital and assets, pursuant to Point c, Clause 4, Article 110 of the 2018 Competition Law.

Auditing Historical Cross-Ownership Milestones and Bank Credit Commitments

In mature corporate groups, historical cross-ownership acts as a blind spot capable of invalidating the entire acquisition structure. Investors must pinpoint the exact timeline when cross-ownership formed, the current ratios, and identify which transactions could unlawfully increase restricted percentages. Companies devoid of state-owned shares or capital contributions that mutually invested or purchased each other’s shares prior to July 1, 2015, are not compelled to divest under current cross-ownership prohibitions. However, enterprises are strictly prohibited from executing any transaction that increases this existing cross-ownership ratio under the 2020 Enterprise Law.

Critical risks that must be integrated into the Legal Due Diligence Report include:

• Cross-ownership ratios established before July 1, 2015, but unlawfully increased by subsequent transactions.
• The target company currently guaranteeing, mortgaging, or committing obligations for affiliated entities.
• Credit agreements containing strict Change of Control (CoC) clauses.
• Banks retain the authority to demand premature debt repayment upon a change in controlling shareholders.
• Financial commitments capable of triggering a Material Adverse Change (MAC) prior to closing.

If a credit agreement mandates bank approval prior to altering control, the SPA must strictly incorporate this requirement into the Conditions Precedent (CPs). Otherwise, the buyer may successfully complete the share transfer but face the catastrophic risk of premature loan recalls.

Designing the Share Purchase Agreement and Shareholders’ Agreement to Lock in Control

The Share Purchase Agreement (SPA) should not merely record the price, ownership percentage, and payment schedule. For a controlling stake acquisition, the contract must strictly control closing conditions, breach liabilities, and post-closing governance rights.

The Shareholders’ Agreement (SHA) acts as the primary instrument to lock in actual control. Without a rigorously drafted SHA, the buyer may hold a majority of shares but still face catastrophic deadlocks when altering personnel, budgets, or business strategies.

Conditions Precedent (CPs) and the Escrow Account Mechanism

Conditions Precedent (CPs) ensure the buyer is not obligated to disburse funds before the transaction fulfills all legal prerequisites. This serves as a vital defense mechanism against hostile reactions from existing shareholders, the Board of Directors (BOD), or the incumbent management board.

The SPA must explicitly stipulate the conditions to be fulfilled prior to closing, including internal approvals, regulatory clearances, completion of information disclosure, and the absence of any Material Adverse Change (MAC). These elements must be framed within the context of shareholder rights, General Meeting of Shareholders (GMS) authority, and BOD jurisdiction under the 2020 Enterprise Law.

A secure disbursement sequence should be structured across the following milestones:

• Signing a conditional SPA, accompanied by a comprehensive list of CPs and non-transfer obligations to third parties.
• Executing an escrow account agreement to strictly control the deposit, share purchase funds, and indemnification retention amounts.
• Securing internal approvals, executing the mandatory public tender offer, or fulfilling the economic concentration notification if required.
• Updating the Shareholder Register and transferring actual control according to the closing dossier.
• Disbursing the remaining funds after the seller fulfills all representations, warranties, and handover obligations.

The escrow mechanism protects the buyer from the severe risk of releasing payments without securing actual control. Simultaneously, the blocked funds serve as an accessible source of indemnification if the seller breaches warranties post-closing.

Establishing the List of Veto Rights and Deadlock Resolution Mechanisms

The SHA must distinctly establish the specific matters over which the buyer holds decisive authority, veto rights, or the right to prior consultation. This strategy effectively converts raw ownership percentages into enforceable management control.

If the target company retains major shareholders or the legacy management board, the buyer must lock down material decisions directly within the SHA. The 2020 Enterprise Law serves as the governing framework for shareholder rights, GMS authority, BOD jurisdiction, and the validity of the corporate charter.

The mandatory list of rights to be established includes:

• The right to nominate, appoint, or dismiss BOD members and key executive personnel.
• Veto rights over resolutions concerning capital increases, capital reductions, share issuance, or alterations to the ownership structure.
• Approval authority over major asset transactions, corporate borrowing, guarantees, and related-party transactions.
• Absolute control over corporate budgets, business plans, investment strategies, and profit distribution.
• Deadlock resolution mechanisms, encompassing high-level negotiations, forced buy-sell clauses, or conditional divestment rights.

Regarding related-party transactions, the contract or transaction price must strictly be the market price at the time of execution, pursuant to Point b, Clause 4, Article 167 of the 2020 Enterprise Law. This provision must be embedded into the SHA to prevent the unlawful dissipation of corporate assets after the buyer assumes control.

Integrating Tag-Along and Drag-Along Rights for Major Shareholders

Tag-along and drag-along rights serve as dual mechanisms to protect the investment value post-transaction. These clauses empower the buyer to control secondary transfers, limit equity dilution, and prevent the seller from transferring remaining shares to market competitors.

The SHA must explicitly stipulate the activation conditions, applicable thresholds, valuation methodologies, and execution timeframes. Otherwise, the buyer may secure control at closing but subsequently lose their strategic advantage when the shareholder structure inevitably shifts.

These mechanisms must perfectly align with the corporate charter and the 2020 Enterprise Law. If the SHA contradicts the charter or lacks transparent enforcement mechanisms, post-M&A governance control will fatally collapse during internal disputes.

Pre-Closing and Post-Closing Action Strategies for M&A Transactions

The pre-closing and post-closing phases dictate whether a transaction successfully translates into actual management control. Buyers must simultaneously control major shareholders, key personnel, shareholder records, and enterprise registration procedures. If the legacy management board reacts hostilely, the risk extends beyond internal disputes. The enterprise may lose critical governance data, suffer severe delays in updating shareholder status, and fail to execute post-M&A integration plans.

Strategies for Approaching Major Shareholders and Key Personnel Retention Agreements

Buyers should approach major shareholders prior to public announcements to mitigate the risk of price inflation or defensive alliances. This strategy must strictly avoid coercion, misrepresentation, or the illegal use of insider information. A major shareholder is defined as a shareholder owning 5% or more of the voting shares of an issuing organization, pursuant to Clause 18, Article 4 of the 2019 Securities Law. Therefore, all strategies engaging this group must be strictly controlled under statutory information disclosure obligations.

Actions to execute prior to closing include:

• Identify major shareholders, internal persons, and affiliated persons.
• Standardize communications regarding post-M&A benefits to neutralize defensive reactions.
• Negotiate key personnel retention agreements tied to KPIs and transitional periods.
• Avoid extra-contractual commitments that could be construed as non-transparent incentives.
• Control internal corporate communications to prevent rumors from disrupting daily operations.

Internal persons and affiliated persons must disclose information regarding their securities transactions within 5 working days from the transaction completion date, pursuant to Point d, Clause 1, Article 33 of Circular No. 96/2020/TT-BTC. This absolute deadline must be hardwired into the closing schedule for public companies.

Procedural Checklist for Updating the Shareholder Register and Changing the Legal Representative

Upon completing the payment, the buyer must instantly shift focus to legalizing their shareholder status and governance authority. Failing to update the Shareholder Register exposes the new shareholder status to fatal disputes during voting.

The post-closing sequence should be structured to generate irrefutable evidence of handover:

• Sign closing minutes confirming the fulfillment of Conditions Precedent (CPs) and payment obligations.
• Demand the target company immediately update the Shareholder Register reflecting the executed transfer dossiers.
• Convene the General Meeting of Shareholders (GMS) or Board of Directors (BOD) to formally record the new governance structure.
• Approve the change of the Legal Representative, management members, or executive titles as mandated by the post-M&A plan.
• Execute the Registration of Changes to Enterprise Registration Content when required by statutory modifications.
• Secure the physical handover of the corporate seal, bank accounts, legal dossiers, material contracts, and governance data.

The 2020 Enterprise Law strictly governs the Shareholder Register, shareholder rights, and modifications to enterprise registration content. Consequently, the SPA must anticipate severe punitive measures if the legacy management board refuses to hand over assets or deliberately delays updating corporate records. When obstruction occurs, buyers must trigger breach clauses and secure evidence to aggressively protect their new shareholder rights.

Opportunities to Reset Project Terms When Acquiring a Legal Entity

In transactions acquiring a project-owning company, the true value of the shares depends directly on the remaining operational term of the asset. If the project is nearing expiration, the buyer must rigorously evaluate the feasibility of resetting the project term during the pre-transaction phase.

For the transfer of an ongoing project implemented before the 2025 Investment Law takes effect, possessing a Land Use Right Certificate and having fulfilled financial obligations, the buyer may propose the competent authority reset the project term. This mechanism aligns with the procedure for approving adjustments or issuing an Investment Registration Certificate under the 2025 Investment Law.

The Legal Due Diligence Report must assess these strategic benefits:

• Increasing the financial valuation of the project if the operational term is legally extended.
• Mitigating the risk of acquiring a legal entity lacking sufficient time for capital recovery.
• Embedding the condition of resetting the project term into the SPA as a strict CP.
• Negotiating a price adjustment mechanism if the competent authority rejects the extension.
• Synchronizing the M&A plan with investment dossiers, land records, and financial models.

This represents a critical focal point for foreign investors acquiring entities with massive land banks or stalled projects. Ignoring the project term leaves the buyer with corporate control but a catastrophic failure to achieve projected economic returns.

Frequently Asked Questions about the Structure of a Controlling Share Acquisition: Mitigating Hostile Risk:

The questions below help investors, major shareholders, and management quickly identify potentially contentious legal issues when implementing controlling stake acquisitions, especially in the context of hostile takeover risks, public tender offer obligations, or economic concentration notification requirements.

Conclusion

A controlling stake acquisition in Vietnam is only secure when the buyer simultaneously dictates critical voting thresholds, the corporate charter, mandatory public tender offers, economic concentration notifications, and post-M&A governance agreements. Merely finalizing the purchase price and signing the SPA without strictly locking in Conditions Precedent, escrow mechanisms, absolute veto rights, personnel appointment protocols, and Shareholder Register updates leaves the investor holding a majority stake but entirely stripped of actual corporate control.
