This guide presents the fundamental legal aspects of M&A transactions in Brazil, covering transaction structures, regulatory processes, contractual negotiation, and risks to be managed.

M&A Transaction Structures

Share Deal

In a share deal, the buyer acquires the seller’s quotas (LTDA) or shares (SA), becoming a partner or shareholder of the target company: Learn more about our real estate law services.

Characteristics:

• Buyer assumes the company with all assets and liabilities
• Immediate operational continuity
• Contracts, licenses, and authorizations generally remain in effect
• Labor, tax, and environmental liabilities are transferred
• Simpler execution structure

Advantages:

• Operational simplicity
• Maintenance of contracts and licenses
• Continuity of commercial relationships
• Possibility of amortizing goodwill for tax purposes

Risks:

• Assumption of hidden liabilities
• Need for rigorous due diligence
• Contingent liabilities may materialize after closing

Asset Deal

In an asset deal, the buyer acquires specific assets from the target company:

Characteristics:

• Buyer selects which assets to acquire
• Liabilities are not automatically transferred (with exceptions)
• Contracts may require third-party consent for transfer
• Licenses and authorizations may need to be reobtained

Advantages:

• Selection of desired assets
• Protection from seller’s liabilities (in theory)
• Structuring flexibility

Risks and considerations:

• Art. 1,146 of the Civil Code: buyer of an establishment is liable for recorded debts
• Labor succession (art. 448 of the CLT): buyer may be liable for labor obligations
• Tax succession (art. 133 of the CTN): buyer may be liable for taxes if acquiring a going concern and the seller ceases operations
• Need to renegotiate contracts

M&A Transaction Stages

1. Preparatory Phase

• Acquisition strategy definition
• Target identification (target screening)
• Preliminary market and competition analysis
• Non-Disclosure Agreement (NDA)
• Teaser and Information Memorandum

2. Preliminary Negotiation

• Letter of Intent (LOI) or Term Sheet
• Indicative price and structure definition
• Exclusivity (no-shop clause)
• Conditions for proceeding (conditions precedent)
• Indicative timeline

3. Due Diligence

Detailed investigation of the target company covering:

• Legal due diligence (corporate, contractual, litigation)
• Financial due diligence (statements, cash flow, indebtedness)
• Tax due diligence (compliance, contingencies, incentives)
• Labor due diligence (liabilities, compliance, outsourcing)
• Environmental due diligence (licenses, liabilities, contamination)
• Regulatory due diligence (authorizations, sector compliance)

For due diligence details, see our business due diligence guide.

4. Negotiation and Documentation

Share Purchase Agreement (SPA):

Essential clauses:

Price and payment:

• Fixed price or with adjustment (locked box vs. closing accounts)
• Payment form (lump sum, installments, earn-out)
• Post-closing price adjustment mechanism
• Escrow account (partial price retention as guarantee)

Representations & Warranties:

• Seller declarations about the company’s condition
• Tax, labor, and environmental compliance
• Absence of hidden liabilities
• Legal and regulatory conformity
• Share ownership and absence of encumbrances
• Truthfulness of information provided during due diligence

Indemnification:

• Seller’s obligation to compensate buyer for losses from false declarations
• Indemnification limit (cap): generally 10% to 100% of the price
• Basket/deductible: minimum amount to trigger indemnification
• Duration: generally 2 to 5 years (tax may extend to 5-10 years)

Conditions Precedent:

• CADE approval (when applicable)
• Partner/shareholder assembly approval
• Third-party consents (contracts with change of control clauses)
• Regulatory agency approval
• Absence of MAC (Material Adverse Change)

Post-closing clauses:

• Operational transition
• Seller non-compete
• Key executive retention
• Final price adjustment

5. Regulatory Approval (CADE)

The Administrative Council for Economic Defense (CADE) must approve transactions meeting mandatory notification criteria.

Notification criteria (art. 88, Law 12,529/2011):

• One group has gross annual revenue of R$ 750 million or more AND
• The other group has gross annual revenue of R$ 75 million or more

Types of review:

Track	Timeline	Application
Summary	20-30 days	~95% of transactions, no competition concern
Ordinary	6-18 months	Transactions with significant anticompetitive potential

Consequences of non-notification:

• Fines from R$ 60,000 to R$ 60,000,000
• Nullity of the concentration act
• Possibility of transaction reversal

CADE notification is prior, meaning closing cannot occur before approval.

6. Closing

Closing is the transaction consummation moment:

• Signing of definitive documents
• Price payment
• Share/quota transfer
• Articles of association amendment at the Junta Comercial
• Foreign capital registration at the Central Bank (if applicable)
• Management transition

Tax Aspects of M&A

Seller Taxation

Individual:

• Capital gains: 15% to 22.5% (progressive rates)
• Tax base: difference between sale price and share acquisition cost

Legal entity:

• IRPJ (15% + 10% surcharge) and CSLL (9%) on capital gains
• PIS and COFINS on gross sale revenue (in some cases)

Buyer Taxation

• Goodwill: difference between price paid and book value

• Planning: structuring with acquisition vehicle (SPE) to optimize goodwill amortization

Tax Risks

• Tax authority challenges to artificial goodwill
• Disregard of transactions lacking economic substance
• Buyer’s tax liability in asset deals
• Earn-out taxation as capital gains vs. income
• Cross-border operations and transfer pricing
