Asset Sale vs Share Sale in Vietnam (renewable Energy Projects), Which Is Better in 2026?

Every renewable energy deal in Vietnam forces a binary structural choice before the term sheet is signed: does the buyer acquire the project company’s assets, or does it purchase the seller’s shares? The question of asset sale vs share sale in Vietnam in 2026 has taken on fresh urgency since the deemed 2% tax on certain share transfer proceeds took effect on 15 December 2025, materially shifting the economics that previously made share deals the default exit route for foreign sponsors.

CFOs, PE investors, and project developers preparing bids on solar, wind, or transitional gas assets must now model both structures in parallel, factoring in VAT exposure, PPA transferability, sectoral consents from EVN and MOIT, land-use registration timelines, and post-closing liability allocation, before committing to either path. This guide delivers a practitioner-level, dimension-by-dimension comparison and a clear decision framework so you can choose the right structure and brief counsel with confidence.

Option A: The Asset Sale, What It Is, When It Applies, and Who It Suits

In an asset sale the buyer cherry-picks individual assets, and, critically, only the liabilities it agrees to assume, from the project company. Title to each asset transfers separately, and the project company itself remains with the seller as an empty or residual shell. For renewable energy projects this structure hands the buyer surgical control over what enters its balance sheet, but it demands a longer, consent-heavy closing process.

Typical Asset Package in a Renewable Energy Project

The asset purchase agreement (APA) in a Vietnamese solar or wind deal will usually cover:

• Land-use rights or lease. The right to use the project site, typically held under a land-use right certificate (LURC) or a long-term lease from the provincial People’s Committee.
• Power Purchase Agreement (PPA) receivables. The contractual right to sell electricity to EVN or a direct purchaser under the DPPA mechanism.
• Grid-connection assets. Substations, transmission lines, and metering equipment connected to the national grid.
• EPC and O&M contracts. Novation or assignment of the engineering, procurement, construction, and operations and maintenance agreements.
• Permits and licences. Electricity generation licence, environmental impact assessment approval, construction permits, and fire-safety certificates.
• Receivables and inventory. Outstanding invoices, spare-parts inventory, and security deposits.

When Buyers and Sellers Use Asset Sales

The asset route suits buyers who want to ring-fence legacy risks, undisclosed tax liabilities, pending environmental claims, or unresolved land disputes, because they can exclude those items from the APA. Buyers also benefit from a potential step-up in the tax cost base of acquired assets, generating higher depreciation deductions going forward. Sellers may accept an asset sale when the project company has significant liabilities the buyer refuses to inherit, or when the seller intends to retain the corporate shell for other purposes.

Key Negotiation Levers

• Representations and warranties. Seller warrants clear title, valid permits, and compliance history for each transferred asset.
• Escrow for tax indemnities. A portion of the purchase price is held in escrow to cover any VAT or CIT assessment that materialises after closing.
• VAT gross-up clause. Where VAT on asset transfers applies (standard rate 10%), the parties must agree who bears the cost and how it is reflected in the headline price.
• Assignment consent programme. The APA should schedule every consent required, PPA counterparty, land authority, grid operator, lender, with a clear timeline and drop-dead date.

Option B: The Share Sale, What It Is, When It Applies, and Who It Suits

In a share sale the buyer acquires the seller’s equity interest in the project company. The company itself, with every asset, contract, permit, and liability on its books, continues to exist. Ownership changes at the shareholder level; the project company’s legal personality and its contractual relationships remain formally intact. For renewable energy M&A in Vietnam, the share route has historically been the more common exit path for foreign sponsors precisely because it preserves PPA continuity, avoids individual asset registrations, and, until December 2025, offered a more efficient tax outcome for many sellers.

Share Sale Mechanics

The share purchase agreement (SPA) transfers legal title to the shares of a limited liability company (LLC) or a joint-stock company (JSC). For an LLC, this involves amending the company’s enterprise registration certificate (ERC) to reflect the new member. For a non-public JSC, the transfer is recorded in the company’s shareholder register. In both cases, the buyer steps into the seller’s shoes as owner of the entity that holds the PPA, the LURC, and every other project document.

When Share Sales Are Preferred

• Speed. A single share transfer is mechanically simpler than dozens of individual asset assignments and registrations.
• PPA continuity. The PPA counterparty (typically EVN) remains contracting with the same legal entity, avoiding the need for a full PPA assignment, though change-of-control clauses may still require consent.
• Utilisation of tax attributes. The project company’s accumulated tax losses (which can be carried forward for up to five years under Vietnam’s CIT rules) stay with the entity and may shelter future taxable income for the buyer.
• Seller preference. Sellers historically favoured share sales for their simpler exit mechanics. However, the post-15 December 2025 tax landscape requires sellers to reassess this preference carefully.

Key Deal Levers

• Purchase price adjustments. Completion accounts or locked-box mechanisms to address working capital, debt, and cash movements between signing and closing.
• Tax warranties and disclosure. Buyer requires comprehensive seller warranties on the company’s tax compliance history and full disclosure of any pending or threatened assessments.
• Change-of-control consent programme. The SPA should list every contract containing a change-of-control clause, PPA, lender facilities, O&M agreements, land leases, with responsibility for obtaining consent allocated to the seller pre-closing.
• Indemnity and escrow. A seller indemnity backed by escrow protects the buyer against pre-existing liabilities, particularly undisclosed tax or environmental obligations.

Asset Sale vs Share Sale, Side-by-Side Comparison for Renewable Energy Projects in Vietnam in 2026

The table below captures the core pros and cons across every dimension that matters in a Vietnamese renewable energy transaction. Use it as a rapid reference before diving into the detailed analysis that follows. The central trade-off is this: asset sales give the buyer cleaner liability protection and a tax step-up but cost more time and regulatory effort; share sales offer speed and contractual continuity but saddle the buyer with inherited risks and, since December 2025, may impose a heavier tax bill on the seller.

Dimension-by-Dimension Analysis

Tax Implications

Tax is the single most consequential dimension in the asset sale vs share sale Vietnam 2026 decision, and the dimension most affected by recent regulatory change. The table below sets out the headline cash effects for each structure.

Practical modelling note. Every deal team should run parallel after-tax models for both structures before the LOI stage. The models should capture: gross sale price, estimated taxable gain under each structure, applicable tax rates and deemed rates, VAT exposure on asset transfers, and the net cash-to-seller after all taxes and withholdings. Where the deemed 2% tax on gross proceeds produces a higher tax charge than CIT at 20% on net gain, the seller has a direct financial incentive to negotiate tax gross-up provisions or shift to an asset deal structure instead.

Vietnam permits corporate tax losses to be carried forward for up to five years. In a share sale, the project company’s accumulated losses remain available to shelter future income, a valuable attribute if the project is in its early revenue years. In an asset sale, those losses stay with the seller’s entity and are unavailable to the buyer. This carryforward benefit can be worth modelling explicitly, particularly for projects that incurred significant pre-commissioning costs.

Timing and Closing Mechanics

Timing drives deal certainty, and the two structures diverge sharply here.

• Asset sale. Expect 3–6 months from signing to closing. Each asset requires separate transfer registration, LURC amendment at the provincial land authority, novation of the PPA with EVN or the off-taker, re-registration of grid-connection agreements, and reassignment of construction and environmental permits. Any single consent delay extends the entire closing timeline.
• Share sale. Mechanically faster, the core transfer is an amendment to the ERC and/or shareholder register. However, change-of-control clauses in the PPA, lender facility agreements, and sometimes O&M contracts can introduce consent requirements that extend the timeline by 4–8 weeks. Foreign buyers must also register the investment change with the Ministry of Industry and Commerce (MIC) and, where applicable, obtain a new or amended foreign investment registration certificate (IRC).

Regulatory Burden and Sectoral Consents

Renewable energy projects in Vietnam sit at the intersection of multiple regulatory authorities. The consent burden differs materially between structures.

The asset sale route typically requires more individual consents and registrations, any one of which can become a bottleneck. Share sales reduce this friction but do not eliminate it: PPA change-of-control clauses and lender consents remain live risks. Deal teams should map every required consent in a conditions-precedent matrix during due diligence, with fallback termination rights if critical consents are not obtained by an agreed long-stop date.

Liability Allocation and Indemnities

Liability exposure is where the two structures diverge most starkly, and where the buyer’s risk appetite should drive the decision.

• Asset sale. The buyer assumes only the liabilities expressly listed in the APA. Pre-existing environmental contamination, undisclosed tax assessments, pending litigation, and construction defects can all be excluded. The seller provides representations and warranties on each transferred asset, backed by an indemnity and, in market practice, an escrow of 5–15% of the purchase price held for 12–24 months.
• Share sale. The buyer inherits everything, disclosed and undisclosed liabilities alike, because the legal entity continues unchanged. Stronger contractual protections are essential: comprehensive tax and compliance warranties, a seller indemnity with a higher cap (often 50–100% of the purchase price for fundamental and tax warranties), and a longer escrow period. Where the market supports it, warranty and indemnity (W&I) insurance can supplement seller protections, although W&I coverage for Vietnam-specific risks remains limited compared to developed markets.

Enforceability of PPAs and Step-In Rights

The PPA is the revenue engine of any renewable project. Its treatment under each structure is a critical decision factor.

• Asset sale, PPA assignment. Assigning the PPA to a new entity typically requires the formal consent of the off-taker (usually EVN). EVN may impose conditions: updated performance security, parent company guarantees, or demonstration of the buyer’s technical capability. If consent is refused or delayed, the deal may fail or require restructuring. Negotiate a backstop: if PPA assignment consent is not obtained by the long-stop date, either party can terminate the APA without liability.
• Share sale, PPA continuity. The PPA stays with the project company, and the contractual counterparty does not change. However, most PPAs contain change-of-control provisions requiring notification to, and sometimes consent from, EVN when the project company’s ownership changes. Industry observers expect EVN to continue treating these consents as largely procedural for well-performing projects, but consent refusal remains a theoretical risk that should be addressed in the SPA through a conditions-precedent framework.

Financing, Security, and Transferability

Project finance structures add a further layer of complexity to both routes.

• Asset sale. Existing security interests, mortgages over the LURC, pledges over equipment, assignments of receivables, must be released by the lender and re-registered in favour of the buyer or the buyer’s new financing arrangements. This requires lender consent and coordination with the registration authorities, adding cost and time.
• Share sale. Lenders often hold a pledge over the project company’s shares as primary security. Transferring those shares triggers the change-of-control clause in the facility agreement, requiring lender consent. In practice, lenders will evaluate the buyer’s creditworthiness and may require new or supplemented guarantees before consenting. If the project’s debt is to be assumed by the buyer, the lender consent process can take 6–10 weeks.

What Changes in 2026, The Tax Pivot That Shifts Deal Economics

The most significant development affecting the asset sale vs share sale calculus in Vietnam is the deemed 2% tax on gross share transfer proceeds, effective 15 December 2025. This rule, widely reported by leading tax advisors including Taxand, Grant Thornton, and Acclime, applies to certain transfers of shares in limited liability companies and non-public joint-stock companies. For foreign corporate sellers of renewable energy project companies, the practical effect is substantial: the tax is levied on gross proceeds, not on net capital gain. On a USD 50 million share sale with a USD 10 million net gain, the old regime would have produced CIT of approximately USD 2 million (20% of the USD 10 million gain).

The new deemed rate produces a tax charge of USD 1 million (2% of USD 50 million), which may be lower in this example, but in deals where the gain-to-price ratio is small, the deemed approach can produce a significantly higher effective tax rate than CIT on the net gain.

In addition, 2026 draft guidance reported by practitioners addresses PIT treatment for resident individual sellers of unlisted shares, with a reported rate of 20% on capital gains. This guidance should be treated as subject to final confirmation, deal teams should verify the latest MOF and General Department of Taxation (GDT) circulars before relying on any specific PIT rate in financial models.

Immediate deal consequences:

• Sellers can no longer assume that a share sale automatically delivers a better after-tax outcome. Run parallel models and compare the 2% deemed rate against CIT on net gain for each specific transaction.
• Buyers should use the new tax environment as a negotiation lever, if the seller faces higher-than-expected share-sale taxes, this may justify a price adjustment or a shift to an asset deal structure.
• SPA drafting. Include a tax gross-up clause allocating responsibility for the deemed tax, and specify whether the purchase price is stated gross or net of seller’s tax obligations. Consider an escrow mechanism to cover any tax assessment that exceeds the parties’ modelled estimate.
• Timing sensitivity. If legislation or circulars introduce further changes, parties with signed-but-unclosed deals may face mid-stream tax shifts. Build a tax-change adjustment mechanism into the SPA to address this risk.

Decision Framework: When to Choose an Asset Sale vs a Share Sale in Vietnam

The choice is not abstract. It turns on a handful of concrete priorities. Use the framework below to identify the structure that fits your transaction.

Choose the asset sale when:

• The buyer needs only selected assets and wants to leave behind specific liabilities (pending litigation, environmental claims, unresolved tax positions).
• The project company has material contingent liabilities that cannot be adequately covered by indemnity and escrow alone.
• The buyer wants a stepped-up tax cost base to maximise depreciation deductions on the acquired assets.
• The buyer has an existing project company and wants to fold the acquired assets into its own entity for operational efficiency.

Choose the share sale when:

• The seller requires a single-step, clean exit and continuity of the PPA, licences, and land-use rights is essential to preserve project value.
• The buyer is comfortable with inherited liabilities and the due diligence has not revealed material undisclosed risks.
• Speed is critical, the buyer needs operational control within weeks, not months.
• The project company holds valuable tax attributes (loss carryforwards, tax incentives) that the buyer can utilise post-acquisition.

When to Engage a Lawyer for This Decision

The asset-vs-share decision is not one to finalise without specialist counsel. Engage an M&A lawyer experienced in Vietnamese renewable energy transactions in any of these situations:

• Pre-LOI tax modelling. You need parallel after-tax models for both structures, including sensitivity analysis for the deemed 2% tax, VAT on asset transfers, and PIT exposure, before you commit to a headline price.
• Due diligence scoping. The scope of legal, tax, environmental, and title due diligence differs materially between asset and share deals. Counsel must design the right workstream from the outset.
• PPA and lender consent programme. Identifying every change-of-control clause, drafting consent request letters, and negotiating fallback provisions if consent is refused or delayed requires sector-specific experience.
• SPA or APA drafting. Tax gross-up clauses, escrow mechanics, indemnity caps, and conditions precedent must be tailored to the chosen structure and the specific risk profile of the project.
• Foreign ownership and investment registration. If the buyer is a foreign entity, the investment registration (IRC) process and any foreign ownership limits applicable to the energy sector must be navigated from the earliest stage of the transaction.
