Case Study: Cross-border acquisition in Americas

Cross-border acquisitions in the Americas present a distinctive combination of opportunity and legal complexity. A buyer entering Brazil, Mexico, Panama or another jurisdiction in the region must simultaneously manage foreign investment restrictions, antitrust clearance, tax structuring and local corporate formalities - often under compressed timelines and with limited local market knowledge. The cost of a poorly structured deal can exceed the acquisition price itself when hidden liabilities, regulatory penalties or post-closing disputes surface. This article walks through a composite case study of a cross-border acquisition in the Americas, covering the legal framework, deal structure options, due diligence priorities, regulatory approvals, closing mechanics and post-closing integration risks.

The Americas do not operate under a single legal regime. Each jurisdiction maintains its own foreign investment law, corporate statute, antitrust framework and tax code. Understanding which layer of law applies - and in which sequence - is the first practical task for any international buyer.

In Brazil, the primary corporate vehicle for an acquisition is governed by the Lei das Sociedades por Ações (Brazilian Corporations Law, Law No. 6.404/1976), which regulates share transfers, shareholder rights and corporate governance. Foreign direct investment is tracked through the Banco Central do Brasil (Brazilian Central Bank) under Resolução BCB No. 278/2022, which requires registration of foreign capital inflows. Antitrust review falls to the Conselho Administrativo de Defesa Econômica (CADE - Administrative Council for Economic Defense), which applies mandatory pre-merger notification thresholds under Law No. 12.529/2011, Article 88.

In Mexico, the Ley General de Sociedades Mercantiles (General Law of Commercial Companies) governs corporate transfers, while the Ley de Inversión Extranjera (Foreign Investment Law) and its implementing regulations set sector-specific restrictions and ownership caps. The Comisión Federal de Competencia Económica (COFECE - Federal Economic Competition Commission) handles merger control under the Ley Federal de Competencia Económica (Federal Economic Competition Law), Articles 86-89.

In Panama, the Código de Comercio (Commercial Code) and the Ley de Sociedades Anónimas (Law on Corporations, Law No. 32 of 1927) provide a flexible corporate framework that international buyers frequently use as an intermediate holding layer. Panama imposes no foreign ownership restrictions on most commercial sectors.

A common mistake among international buyers is treating the Americas as a single legal bloc. The civil law tradition shared by Brazil, Mexico and Panama diverges significantly in procedural detail, enforcement culture and judicial reliability. A deal structure that works seamlessly in one jurisdiction may trigger unexpected tax exposure or regulatory scrutiny in another.

The choice between acquiring shares and acquiring assets is the most consequential structural decision in any cross-border acquisition. Each path carries distinct legal, tax and liability implications that vary by jurisdiction.

A share deal transfers the entire legal entity, including its contracts, licences, employees, tax history and contingent liabilities. In Brazil, a share transfer in a sociedade anônima (joint-stock company) requires a formal amendment to the company';s estatuto social (articles of association) and registration with the Junta Comercial (Commercial Registry). In a sociedade limitada (limited liability company), the transfer is recorded in the contrato social (articles of organisation). The buyer inherits all pre-existing liabilities, including labour claims, tax debts and environmental obligations - many of which may not appear on the balance sheet.

An asset deal allows the buyer to select specific assets and liabilities, leaving unwanted exposures with the seller. In Mexico, this structure requires individual transfer of each asset class: real property through notarial deed, intellectual property through registration with the Instituto Mexicano de la Propiedad Industrial (IMPI - Mexican Institute of Industrial Property), and contracts through novation or assignment with counterparty consent. The procedural burden is higher, but the liability ring-fence is cleaner.

In practice, it is important to consider that Brazilian labour law creates successor liability even in asset deals when the buyer acquires the productive unit as a going concern. Article 448 of the Consolidação das Leis do Trabalho (Consolidated Labour Laws) provides that employment contracts survive a change of employer, and courts have extended this principle to asset transactions that effectively transfer the business as a whole.

A non-obvious risk is the treatment of tax liabilities in share deals across the region. In Mexico, the Código Fiscal de la Federación (Federal Tax Code), Article 26, establishes joint and several liability for tax debts of an acquired entity under certain conditions. Buyers who rely solely on seller representations without independent tax due diligence frequently discover this exposure only after closing.

The business economics of the structural choice depend on the deal size and the nature of the target. For acquisitions below USD 10 million, the procedural cost of an asset deal may consume a disproportionate share of the transaction budget. For larger deals with complex liability profiles, the asset deal premium is often justified.

Due diligence in a cross-border acquisition in the Americas must cover legal, financial, tax, labour, environmental and regulatory dimensions. The sequence and depth of each workstream depend on the target';s sector, size and jurisdiction.

Legal due diligence begins with corporate title verification. In Brazil, the buyer must confirm chain of title through the Junta Comercial records and verify that all prior share transfers were properly executed and registered. A gap in the corporate chain - even a technical one - can delay closing or create post-closing disputes over ownership validity.

Labour due diligence is disproportionately important in Brazil and Mexico. Both jurisdictions have employee-protective labour regimes with significant contingent liability exposure. In Brazil, labour claims are adjudicated by the Justiça do Trabalho (Labour Court), which applies a five-year statute of limitations for claims arising during employment and a two-year window post-termination under Article 7(XXIX) of the Constituição Federal (Federal Constitution). Undisclosed labour contingencies routinely represent the largest single liability category in Brazilian acquisitions.

Tax due diligence must address not only declared tax positions but also the target';s exposure under ongoing or potential audits. In Mexico, the Servicio de Administración Tributaria (SAT - Tax Administration Service) has broad audit powers and can reassess up to five years of prior tax returns under Article 67 of the Federal Tax Code. Buyers should obtain tax clearance certificates where available and negotiate robust indemnity provisions for pre-closing tax periods.

Environmental due diligence is critical for targets in extractive industries, manufacturing or real estate. Brazil';s Lei de Crimes Ambientais (Environmental Crimes Law, Law No. 9.605/1998) imposes criminal and civil liability on legal entities for environmental violations, and this liability transfers with ownership in a share deal. Phase I and Phase II environmental assessments are standard practice for industrial targets.

Regulatory due diligence must map all licences, permits and authorisations held by the target and assess whether they are transferable. In regulated sectors - banking, insurance, telecommunications, energy - a change of control may require prior approval from the relevant regulator, and closing before that approval is obtained can render the transaction void or subject to unwinding.

A common mistake is compressing the due diligence timeline to meet a seller';s preferred closing schedule. In cross-border transactions, document retrieval from local registries, translation requirements and the need to engage local counsel in multiple jurisdictions typically require a minimum of 45 to 60 days for a thorough review. Buyers who accept shorter windows frequently discover material issues only after signing.

Regulatory approvals represent the most significant source of deal timeline uncertainty in cross-border acquisitions in the Americas. Antitrust clearance, foreign investment review and sector-specific approvals can each add months to the closing schedule.

CADE in Brazil operates a mandatory pre-merger notification system. Notification is required when the combined group has annual revenues in Brazil exceeding BRL 750 million and the target has revenues exceeding BRL 75 million, under Law No. 12.529/2011, Article 88. CADE has a statutory review period of 240 days, extendable to 330 days in complex cases. The vast majority of transactions receive clearance within 30 to 60 days under the fast-track procedure, but deals with significant horizontal overlaps or vertical integration concerns can take considerably longer.

COFECE in Mexico applies a similar pre-merger notification regime. Thresholds are set by reference to transaction value and the parties'; Mexican revenues under the Federal Economic Competition Law, Article 86. COFECE has 60 business days to complete its initial review, with a possible extension of 40 additional business days for complex cases. Failure to notify when required exposes the parties to fines and potential unwinding of the transaction.

Foreign investment review adds a separate layer. In Brazil, acquisitions in financial services, insurance and certain infrastructure sectors require approval from the Banco Central, the Superintendência de Seguros Privados (SUSEP - Private Insurance Superintendency) or the Agência Nacional de Energia Elétrica (ANEEL - National Electric Energy Agency), depending on the sector. In Mexico, the Comisión Nacional de Inversiones Extranjeras (National Foreign Investment Commission) reviews acquisitions in restricted sectors and those exceeding specified value thresholds under the Foreign Investment Law, Article 8.

In practice, it is important to consider that regulatory timelines in the Americas are not always predictable. Agencies may issue information requests that pause the statutory clock, and political or policy considerations can influence the pace of review in sensitive sectors. Buyers should build regulatory contingency periods of at least 90 days into their deal timelines and negotiate appropriate termination rights if approvals are not obtained within a defined outside date.

The risk of inaction is concrete: a buyer who proceeds to closing without required antitrust clearance in Brazil faces fines of up to 20% of the group';s Brazilian revenues under Law No. 12.529/2011, Article 37, and CADE has the power to order divestiture of the acquired business.

The closing of a cross-border acquisition in the Americas involves a sequence of interdependent steps that must be carefully coordinated across jurisdictions, currencies and time zones.

The signing and closing may occur simultaneously or be separated by a pre-closing period during which conditions precedent are satisfied. Conditions typically include regulatory approvals, material adverse change confirmations, third-party consents and the delivery of closing deliverables. The purchase agreement - governed by the law of the chosen jurisdiction - should specify each condition with precision, including the standard for satisfaction and the consequences of non-satisfaction.

Escrow arrangements are standard practice in cross-border Americas deals. A portion of the purchase price - commonly 10 to 15 percent - is held in escrow for a period of 12 to 24 months to secure the seller';s indemnification obligations. The escrow agent is typically a major international bank or a neutral third-party financial institution. The escrow agreement must specify the release conditions, dispute resolution mechanism and governing law.

Purchase price adjustments are common in deals where the target';s financial position may change between signing and closing. The most frequent mechanism is a locked-box structure or a completion accounts adjustment based on working capital, net debt and cash. In Brazil, the adjustment calculation must account for the target';s functional currency and the impact of exchange rate movements on BRL-denominated assets and liabilities.

Representations and warranties insurance (RWI) has become increasingly available in Latin American transactions. RWI policies allow the buyer to claim directly against an insurer for breaches of seller representations, reducing reliance on the seller';s indemnification capacity. Premiums for RWI in the Americas typically start from the low single-digit percentage of the insured amount, and the underwriting process requires a thorough due diligence report.

A non-obvious risk in Brazilian closings is the requirement to register the foreign capital inflow with the Banco Central within 30 days of the transfer. Failure to register on time does not invalidate the transaction but can create complications for future dividend remittances and capital repatriation, as unregistered foreign capital loses the right to remit profits abroad under Resolução BCB No. 278/2022.

Post-closing integration is where many cross-border acquisitions in the Americas encounter their most serious difficulties. Legal, cultural and operational misalignments that were manageable during the deal phase can become acute once the buyer assumes control.

Employment integration requires immediate attention. In Brazil, changes to employment terms post-acquisition must comply with the Consolidação das Leis do Trabalho, which restricts unilateral modifications that are detrimental to employees. Redundancy programmes must follow the procedural requirements of the relevant collective bargaining agreement and, for mass layoffs, may require prior negotiation with the union under Article 477-A of the CLT. The cost of a poorly managed workforce integration - including labour claims, productivity loss and management distraction - can be substantial.

Intellectual property consolidation is a priority for technology and consumer brand acquisitions. In Brazil, IP rights are registered with the Instituto Nacional da Propriedade Industrial (INPI - National Institute of Industrial Property). Post-closing, the buyer must update registration records to reflect the change of ownership. Delays in updating IP registrations create a window during which third parties may challenge the buyer';s title or register conflicting marks.

Dispute resolution provisions in the acquisition agreement determine how post-closing disagreements are resolved. International arbitration is the preferred mechanism for cross-border Americas deals, typically under the rules of the International Chamber of Commerce (ICC) or the American Arbitration Association (AAA). Arbitration seated in New York, Miami or São Paulo provides enforceability under the New York Convention on the Recognition and Enforcement of Foreign Arbitral Awards, to which Brazil, Mexico and Panama are all parties.

Three practical scenarios illustrate the range of post-closing risks:

• A European buyer acquires a Brazilian manufacturing company and discovers, 18 months post-closing, a series of undisclosed labour claims filed before the closing date. The escrow fund covers part of the exposure, but the buyer must initiate arbitration against the seller for the balance under the indemnification provisions.
• A North American private equity fund acquires a Mexican retail chain and encounters resistance from the target';s management team, which holds minority shares with tag-along and veto rights under the shareholders'; agreement. The fund must negotiate a buyout of the minority at a premium to achieve full operational control.
• A pan-regional conglomerate acquires a Panamanian holding company with subsidiaries in three countries. Post-closing, a tax audit in one subsidiary reveals transfer pricing adjustments that increase the effective acquisition cost by a material amount. The buyer';s ability to recover depends on the scope of the tax indemnity negotiated at signing.

Exit planning should be considered at the acquisition stage, not after integration difficulties emerge. The choice of corporate vehicle, the jurisdiction of the holding company and the terms of any shareholders'; agreement all affect the buyer';s ability to exit through a secondary sale, IPO or dividend recapitalisation. Many underappreciate that restrictions on share transfers embedded in Brazilian or Mexican corporate documents can significantly reduce exit optionality years after closing.

The loss caused by an incorrect exit strategy can be measured not only in transaction costs but in the time value of capital locked in an illiquid position. Buyers who structure their acquisition without considering exit mechanics from the outset frequently face a choice between accepting a discounted exit price or incurring significant restructuring costs.

What is the most significant legal risk in a cross-border acquisition in Brazil?

The most significant legal risk is undisclosed labour and tax contingencies that transfer with the target entity in a share deal. Brazilian labour courts apply broad successor liability principles, and tax assessments can reach back five years. Buyers who rely on seller representations without independent verification of labour and tax exposures frequently encounter material claims post-closing. A robust due diligence process, combined with escrow retention and specific indemnity provisions, is the standard mitigation approach. Representations and warranties insurance can provide an additional layer of protection where the seller';s indemnification capacity is uncertain.

How long does a cross-border acquisition in Mexico typically take from signing to closing?

The timeline depends primarily on whether COFECE pre-merger notification is required and whether sector-specific regulatory approvals apply. A straightforward transaction without mandatory notification can close in 30 to 45 days from signing. A notifiable transaction adds a minimum of 60 business days for COFECE review, plus time for information requests and any remedies negotiation. Deals requiring approval from a sector regulator - such as the Comisión Nacional Bancaria y de Valores (CNBV - National Banking and Securities Commission) for financial sector targets - should budget 6 to 12 months from signing to closing. Buyers who underestimate regulatory timelines risk breaching financing commitment deadlines or losing deal momentum.

When should a buyer choose international arbitration over local courts for post-closing disputes in the Americas?

International arbitration is preferable in virtually all cross-border Americas acquisitions where the dispute value justifies the cost. Local courts in Brazil and Mexico are competent and independent, but proceedings can extend over several years, and enforcement of foreign judgments involves additional procedural steps. Arbitration under ICC or AAA rules with a neutral seat provides a faster, more predictable process and produces an award enforceable under the New York Convention in over 170 countries. The threshold at which arbitration becomes economically viable depends on the cost structure of the chosen institution, but for disputes above USD 500,000, the procedural advantages of arbitration generally outweigh the cost differential compared to local litigation.

Cross-border acquisitions in the Americas reward buyers who invest in legal preparation before signing and maintain disciplined execution through closing and integration. The region';s diversity of legal systems, regulatory frameworks and enforcement cultures means that generic deal structures imported from other markets frequently underperform. The most successful transactions combine rigorous jurisdiction-specific due diligence, a deal structure calibrated to the target';s liability profile, proactive regulatory engagement and post-closing integration planning that accounts for local labour, IP and tax requirements.
