Cross-Border M&A:
Legal Guide to CFIUS, FIRPTA, and Inbound US Transactions

Why Cross-Border M&A Is Legally Distinctive

A domestic acquisition in the United States involves a known legal environment: Delaware corporate law or the applicable state statute, established antitrust thresholds, familiar contract conventions, and a single regulatory jurisdiction for most approvals. Cross-border transactions operate in two or more legal systems simultaneously, each with its own procedural rules, disclosure obligations, and enforcement mechanisms. The interaction between those systems creates friction that does not exist in purely domestic deals.

The most significant distinguishing element is national security review. The United States has maintained a formal review mechanism for foreign acquisitions of US businesses since the late 1970s, and that mechanism has expanded materially in scope since the Foreign Investment Risk Review Modernization Act of 2018 (FIRRMA). CFIUS now reviews transactions that would not have triggered review under prior law: minority investments, real estate proximate to military installations, and investments in non-controlling positions in sensitive technology companies. The expanded scope means that many transactions a foreign buyer might not historically have flagged as presenting regulatory risk now require careful analysis before any binding commitment is made.

Beyond CFIUS, cross-border transactions implicate tax regimes that do not apply to domestic deals. FIRPTA withholding, foreign tax credits, treaty-based reduced withholding rates, and transfer pricing rules each require specialist analysis. Parties often engage both US and foreign tax counsel, with the US counsel taking primary responsibility for the acquisition agreement tax provisions and the foreign counsel advising on the seller's or buyer's home-country implications. Coordinating those two workstreams without creating inconsistent positions in the transaction documents is a material drafting and project management challenge.

Export control law adds a third dimension. If the target handles technology, software, or technical data subject to EAR or ITAR jurisdiction, a foreign buyer's acquisition may constitute a deemed export requiring a license before any technology transfer can occur. That analysis must happen before the deal is structured, not at the closing table. See also M&A deal structures and Acquisition Stars M&A transaction services for foundational context on the legal framework within which these additional layers operate.

Inbound vs. Outbound Transaction Framing

The starting point for any cross-border analysis is identifying the direction of the transaction. An inbound transaction involves a foreign buyer acquiring a US business or a meaningful interest in a US business. An outbound transaction involves a US acquiror acquiring a foreign target. The regulatory framework, the diligence priorities, and the structural options differ materially depending on which direction the transaction flows.

Inbound transactions are the primary focus of this guide because they trigger the most US-specific regulatory concerns: CFIUS review, FIRPTA withholding, and the array of federal sector-specific ownership restrictions. A foreign buyer approaching a US target must understand from the outset that the US regulatory framework is not negotiable and cannot be contracted around. If CFIUS jurisdiction attaches, the parties must engage with the Committee on its terms and timeline, regardless of what the purchase agreement says about closing conditions.

Outbound transactions present a different profile. A US company acquiring a foreign business must navigate the target's home-country regulatory framework, which may include foreign investment review in the target's jurisdiction, antitrust filings in multiple markets, employment law obligations (particularly in the European Union, where works council consultation requirements can delay a transaction by months), and local law requirements for the transfer of specific asset types. The US buyer must also consider FCPA compliance obligations post-close if the target operates in jurisdictions with elevated corruption risk.

Many transactions do not fit cleanly into either category. A cross-border merger involving US and foreign parties, a joint venture between a US company and a foreign strategic, or an acquisition of a multinational with operations in both the United States and abroad may trigger regulatory review in multiple jurisdictions simultaneously. In those cases, counsel must sequence filings strategically, identify which regulatory clearance sits on the critical path, and plan closing conditions around the longest lead-time approval. Deal structure options are covered in depth at asset purchase vs. stock purchase; the choice between those structures carries significant cross-border implications in terms of which regulatory regimes attach and how.

CFIUS Overview and Covered Transactions

The Committee on Foreign Investment in the United States is an interagency body chaired by the Secretary of the Treasury. Its membership includes the Secretaries of State, Defense, Commerce, Energy, and Homeland Security, as well as the Director of National Intelligence, the United States Trade Representative, and other senior officials. CFIUS is not a court and does not follow judicial procedures; it is an executive branch body that operates under statutory authority and its own regulations, found primarily at 31 C.F.R. Parts 800 and 801.

CFIUS has jurisdiction over "covered transactions," a term defined by statute and regulation. The core category is a foreign person's acquisition of control over a US business. Control is broadly defined and does not require majority ownership; a minority investor with the ability to make or veto key decisions, appoint board members, or access non-public technical information may be exercising control within CFIUS's meaning. FIRRMA expanded CFIUS jurisdiction to include certain non-controlling investments in TID US businesses (discussed in detail below) and transactions involving real estate proximate to sensitive US government facilities.

A covered transaction does not automatically trigger a mandatory filing. CFIUS operates on a voluntary notice system for most transactions, meaning the parties may choose whether to file. However, voluntarily filing and receiving clearance provides a safe harbor against future CFIUS action. A transaction that closes without filing remains subject to CFIUS jurisdiction indefinitely; the Committee can initiate a review at any time after closing if new information surfaces. For transactions with any national security adjacency, the risk of post-close CFIUS intervention is a significant consideration that weighs in favor of filing. Detailed analysis of the covered transaction framework is available at CFIUS review in cross-border M&A.

The CFIUS process begins with the parties submitting a joint voluntary notice or a short-form declaration. Declarations are limited to 30 days of review and result in a limited set of outcomes: CFIUS may clear the transaction, request a full notice, or take no action (which does not constitute clearance). Full notices trigger the 30-day initial review period, with a possible 45-day investigation phase. During those periods, CFIUS staff will conduct classified and unclassified analysis, request supplemental information, and may propose mitigation measures as a condition of clearance. Parties should engage experienced CFIUS counsel early and plan for pre-filing consultations with CFIUS staff before submitting a formal notice.

Mandatory vs. Voluntary CFIUS Filings

FIRRMA introduced mandatory filing requirements for a defined category of transactions. A mandatory filing is required when: (1) a foreign person acquires a controlling interest in a TID US business; (2) a foreign government-linked investor acquires any interest (including a non-controlling interest) in a TID US business that would give the investor certain governance rights; or (3) a transaction involves the acquisition of certain real estate in close proximity to military installations or other sensitive facilities. The mandatory filing must be submitted as a declaration (the short-form filing) unless CFIUS requests a full notice.

Failure to submit a mandatory declaration or notice is a civil violation of the regulations. CFIUS has authority to impose civil penalties of up to the value of the transaction per violation. In extreme cases, CFIUS can recommend that the President block or unwind a transaction that was completed without a required filing. The risk of penalty is not hypothetical; CFIUS has assessed penalties in recent years and has shown increasing willingness to scrutinize transactions that were not voluntarily filed.

Voluntary filings cover the large category of transactions that are covered but not subject to mandatory review. For these transactions, the parties have a choice: file and obtain clearance, or close without filing and accept the residual risk of CFIUS initiating a review post-close. The analysis turns on the transaction's national security profile, the identity of the foreign buyer and its home country's relationship with the United States, the nature of the US business's technology, data, and relationships, and the buyer's tolerance for post-close uncertainty. For most transactions involving a foreign buyer from a country that has not entered into bilateral security agreements with the United States (the so-called "Five Eyes Plus" countries generally receive more favorable treatment), a voluntary filing is the lower-risk course.

The CFIUS timeline must be integrated into the deal schedule at the LOI stage. Purchase agreements should include CFIUS filing obligations as covenants and CFIUS clearance as a closing condition. Termination rights keyed to CFIUS timelines, along with reverse termination fees if CFIUS blocks the deal, are standard market terms in transactions with meaningful CFIUS risk. Counsel should also address what happens to transaction documents and deal economics if CFIUS imposes mitigation conditions, including operational restrictions, divestiture of certain business lines, or requirements for a security agreement administered by a government-appointed monitor.

Industry Sectors Triggering Heightened Review

The TID US business framework is the heart of CFIUS's expanded jurisdiction under FIRRMA. TID stands for technology, infrastructure, and data. A TID US business is one that: produces, designs, tests, manufactures, fabricates, or develops one or more critical technologies; performs functions that CFIUS has identified as covered investment critical infrastructure (CICI); or maintains or collects sensitive personal data of US citizens. Each of these three prongs is defined in detail in the CFIUS regulations and carries its own set of compliance questions.

Critical technology includes items controlled under the Export Administration Regulations (EAR), the International Traffic in Arms Regulations (ITAR), the Atomic Energy Act, and a category of "emerging and foundational technologies" identified by Commerce for special control. Software used in covered critical infrastructure functions, certain encryption items, and defense articles and services are all within scope. A US company that holds an ITAR registration or that exports products under an EAR license is almost certainly a TID US business for CFIUS purposes.

Covered investment critical infrastructure encompasses a detailed list of sectors in the CFIUS regulations: telecommunications, electrical power, natural gas, water, transportation (including rail, aviation, maritime, and pipelines), financial services (including payment systems and financial market utilities), healthcare and public health, chemical facilities, defense industrial base facilities, and certain other sensitive sectors. Ownership of, or access to, covered infrastructure in any of these sectors triggers CFIUS jurisdiction even for non-controlling investments by certain foreign persons.

Sensitive personal data is defined to include certain categories of data about US persons: financial data, health or genetic data, geolocation data, biometric identifiers, and data from consumer devices used in the home. A business that collects or maintains identifiable data about US persons at scale in any of these categories falls within CFIUS's TID jurisdiction. The data prong is particularly relevant for technology platforms, healthcare companies, consumer applications, and any business that operates a loyalty or subscription program with significant US user enrollment. Buyers should assess the target's data practices and retention policies as an early step in cross-border diligence.

FIRPTA Withholding on Foreign Sellers

The Foreign Investment in Real Property Tax Act of 1980 (FIRPTA) imposes a withholding obligation on buyers who purchase US real property interests (USRPIs) from foreign persons. The withholding rate is 15 percent of the amount realized by the seller, which is generally the purchase price. The withholding is not a tax on the buyer; it is a mechanism to collect the tax that the foreign seller owes on any gain from the disposition. However, if the buyer fails to withhold and remit the required amount to the IRS, the buyer becomes jointly and severally liable for the tax, with potential penalties on top.

FIRPTA's scope in M&A is broader than many parties initially appreciate. A stock purchase of a US corporation whose assets consist primarily of US real property triggers FIRPTA because the corporation is treated as a US real property holding corporation (USRPHC). The threshold is whether 50 percent or more of the corporation's assets are USRPIs at any time during the prior five-year period. An acquisition of a business that owns commercial real estate, industrial facilities, or significant land holdings must be analyzed for USRPHC status before the deal structure and payment mechanics are finalized.

The buyer's withholding obligation can be reduced or eliminated through a FIRPTA withholding certificate issued by the IRS. A withholding certificate is obtained by the seller (or jointly by the parties) by filing Form 8288-B with the IRS, demonstrating that the maximum tax on the transaction is less than the standard 15 percent withholding amount or that no withholding is due. The IRS has a 90-day statutory period to act on a withholding certificate application, though in practice response times vary. If a certificate is not obtained before closing, the buyer must withhold and escrow the statutory amount pending IRS action. Detailed treatment of the withholding mechanics and exemption procedures is available at FIRPTA withholding for foreign sellers.

Parties should negotiate who bears the economic cost of FIRPTA withholding in the purchase agreement. A seller subject to FIRPTA withholding who has a minimal gain position (for example, a foreign seller who acquired US real property at a high basis) may face withholding well in excess of actual tax owed. In those cases, prompt filing for a withholding certificate is critical. Buyers should also confirm that FIRPTA does not apply via an applicable exemption: transactions below $300,000 where the buyer uses the property as a residence, shares of publicly traded corporations, and certain other categories are exempt. Those exemptions rarely apply in M&A but should be confirmed.

Inbound Foreign Buyer Ownership Restrictions by Industry

Beyond CFIUS, a set of US statutes directly restrict or prohibit foreign ownership of businesses in specific regulated industries. These restrictions are separate from and cumulative with CFIUS review; they are administered by sector-specific regulators and require their own approval processes. The buyer and its counsel must map these restrictions at the outset of any inbound transaction involving a regulated US business, because they can fundamentally alter deal structure and timeline.

The communications sector is governed by the Communications Act, which prohibits a foreign person or entity from holding more than 20 percent of the stock of a common carrier licensee directly, or more than 25 percent indirectly through a parent holding company. The FCC has discretion to allow higher foreign ownership in certain circumstances but must affirmatively approve any ownership structure that exceeds the statutory thresholds. FCC foreign ownership review is separate from CFIUS and can run concurrently, but the FCC process has its own petitioning requirements and public comment periods. Transactions involving any broadcast license, common carrier license (including wireless), or satellite authorization must include FCC approval as a closing condition.

Aviation is subject to the Federal Aviation Act and DOT regulations, which limit foreign ownership of US air carriers to 25 percent of voting shares and 49 percent of total equity. The "actual control" of a US airline must remain with US citizens. These restrictions apply to certificated air carriers and do not affect general aviation or Part 135 charter operations in the same way, though any transaction involving a carrier holding DOT economic authority requires DOT approval. The maritime sector has similarly strict requirements under the Jones Act and the Shipping Act; US-flagged vessels engaged in coastwise trade must be owned by US citizens.

Foreign acquisition of certain nuclear facilities requires NRC approval under the Atomic Energy Act. Banks and bank holding companies are subject to the Bank Holding Company Act and require Federal Reserve approval for foreign control. Insurance is primarily state-regulated; most states require Form A approval before a person can acquire control of a domestic insurer, and several states impose additional requirements on foreign acquirors. A comprehensive overview of inbound restrictions and the approval processes for each regulated sector is at inbound foreign buyer M&A restrictions.

FCC, FAA, DOT, and Sectoral Approvals

Sectoral regulatory approvals in cross-border transactions require parallel management with CFIUS review, antitrust filings, and the principal M&A negotiation. Each regulatory body has its own procedural timeline, filing requirements, and review standards. A failure to coordinate these workstreams can result in one regulatory process holding the deal open long after all other conditions are satisfied, imposing unnecessary carry costs and deal uncertainty on both parties.

FCC applications for assignment or transfer of control of broadcast and common carrier licenses typically take 60 to 90 days from public notice for uncontested transactions, though applications involving foreign ownership above statutory thresholds or national security questions referred to the Executive Branch's Team Telecom process can take substantially longer. Team Telecom review, conducted by DOJ, DHS, and DOD, operates on a timeline separate from the FCC's own review and can add months to a transaction involving telecommunications infrastructure with national security implications. Parties should initiate Team Telecom engagement as early as possible and should not assume that CFIUS clearance resolves Team Telecom concerns, because the two processes ask distinct questions.

DOT approval for acquisition of a certificated air carrier is required under 49 U.S.C. Section 41105. The DOT review evaluates whether the proposed acquisition is consistent with the public interest and whether the carrier will remain under actual US control post-close. FAA does not separately approve ownership changes, but the FAA must be notified and any relevant operating certificates must be confirmed to remain in effect post-transaction. State public utility commission approvals are required for acquisitions of electric utilities, natural gas distribution companies, and water utilities in many states, and those processes are independent of any federal regulatory review.

The deal timeline for a transaction requiring multiple sectoral approvals should be built backward from the most restrictive approval timeline, not forward from a hoped-for closing date. Counsel should prepare a regulatory map at LOI that identifies every approval required, the applicable procedural timeline for each, any early-filing opportunities, and the dependencies among processes. See Acquisition Stars M&A transaction services for how the firm approaches multi-regulatory deal management.

Export Controls and ITAR Considerations

US export control law operates through two primary regimes. The Export Administration Regulations (EAR), administered by the Commerce Department's Bureau of Industry and Security (BIS), control the export of commercial and dual-use goods, software, and technology. The International Traffic in Arms Regulations (ITAR), administered by the State Department's Directorate of Defense Trade Controls (DDTC), control the export of defense articles, defense services, and related technical data listed on the United States Munitions List (USML). Both regimes apply extraterritorially in certain circumstances and both carry significant civil and criminal penalties for violations.

In M&A, the critical export control concept is the deemed export. Under both EAR and ITAR, a transfer of controlled technology to a foreign national within the United States constitutes an export to that person's country of citizenship or most recent permanent residence. A foreign buyer whose personnel gain access to EAR- or ITAR-controlled technology during due diligence or post-close integration is subject to the export control rules, regardless of geography. If the target's technology is controlled and the foreign buyer's personnel are nationals of a country for which the applicable technology is restricted, a license or agreement with BIS or DDTC may be required before any access is permitted.

The threshold question in export control diligence is whether the target is registered with DDTC under ITAR or exports any items under an EAR export license or license exception. A target that is registered with DDTC is an ITAR-regulated entity, and any change of ownership that results in a foreign person acquiring control triggers ITAR's change-of-ownership requirements. Specifically, the target must notify DDTC of the change of control and may not transfer ITAR-controlled articles or data to the new foreign owner until DDTC has reviewed the transaction. Failure to notify is an ITAR violation, and failure to obtain required authorization before transfer is a separate, potentially more serious violation.

Buyers should request a complete export compliance audit as part of M&A diligence. That audit should cover the target's ITAR registration status, any pending or past DDTC voluntary disclosures or enforcement actions, current EAR export licenses and their conditions, classification of key products and technologies under both EAR and ITAR, and the target's internal export compliance program. A target with an active DDTC registration and a sound compliance program is in a materially better position than one that has never assessed its ITAR obligations.

Tax Treaty and Withholding Framework

The United States has income tax treaties with more than 60 countries. These treaties modify the default US tax rules in ways that can materially affect cross-border M&A economics. At the most basic level, treaties reduce or eliminate US withholding tax on dividends, interest, and royalties paid to residents of treaty countries. In an M&A context, treaty benefits affect the ongoing tax cost of operating a US subsidiary under foreign ownership, the withholding on purchase price payments structured as earnouts or deferred consideration, and the withholding on post-close intercompany payments between the US entity and its new foreign parent.

Treaty eligibility is not automatic for every entity formed in a treaty country. Most modern US tax treaties include a limitation on benefits (LOB) article that restricts treaty access to entities that meet specified ownership and other tests designed to prevent treaty shopping. A foreign buyer whose ownership structure was not designed with US treaty access in mind may find that its holding company does not qualify for treaty benefits, increasing the effective withholding tax on US-source income. Pre-acquisition restructuring to optimize treaty access is a recognized planning technique but requires careful coordination with tax counsel and must be completed before the acquisition closes.

Beyond withholding, treaty provisions affect the characterization of the acquisition itself. Treaties generally do not override FIRPTA withholding on US real property interests; FIRPTA applies regardless of treaty status unless a specific treaty provision addresses it (and most do not). Treaties do affect the treatment of deemed dividends arising from certain acquisition structures, the availability of US foreign tax credits to US sellers with foreign operations, and the treatment of post-close intercompany loans as equity or debt. These issues require tax counsel analysis specific to the buyer's and seller's jurisdictions and cannot be resolved by general treaty observation.

The purchase agreement should address withholding tax obligations clearly, including the party responsible for bearing the cost of any applicable withholding, the obligation to cooperate in obtaining reduced withholding rates or exemptions, and the treatment of any grossed-up payments if withholding applies to consideration that the parties intended to deliver net. Indemnification provisions in cross-border transactions frequently include specific protections for pre-closing tax periods and for tax assessments arising from the transaction structure itself. See indemnification provisions in M&A for a full treatment of the contractual framework.

Anti-Boycott and Sanctions (OFAC)

The Office of Foreign Assets Control (OFAC) administers more than 30 sanctions programs targeting specific countries, governments, entities, and individuals. OFAC sanctions are not purely extraterritorial in their reach: they apply to US persons, to transactions in US dollars, and to transactions that pass through US correspondent banking relationships. A cross-border M&A transaction that involves any of these touchpoints is subject to OFAC review, even if neither party is a US company and the target operates entirely outside the United States.

In an inbound transaction where a foreign buyer is acquiring a US business, OFAC exposure primarily arises in two ways. First, the foreign buyer or any of its significant beneficial owners may be on the Specially Designated Nationals (SDN) list or subject to a country-based comprehensive sanctions program. A US company cannot sell to an SDN, and a seller that fails to conduct adequate OFAC screening before signing a purchase agreement may face enforcement liability. Second, the US target may have customers, suppliers, or service providers that are SDNs or that operate in comprehensively sanctioned jurisdictions. Continued business with those counterparties post-close would make the buyer a US person engaged in sanctionable conduct.

The anti-boycott rules add a distinct compliance obligation. US persons, including US subsidiaries of foreign companies, are prohibited from agreeing to refuse to do business with a boycotted country or with companies blacklisted by a foreign boycott. Violations include agreeing to provide boycott-related information, certifying non-participation in business with Israel, and discriminating against employees on the basis of religion or national origin pursuant to a foreign boycott. In M&A diligence, counsel should review the target's standard contracts, particularly those with Middle Eastern counterparties, for any provision that would require a US person to take a position in support of a foreign boycott. The penalties for anti-boycott violations include civil penalties administered by BIS and criminal penalties under the Export Administration Act.

OFAC and anti-boycott representations in the purchase agreement should be paired with specific diligence obligations: a requirement that the seller represent the results of its own OFAC screening, a covenant to cooperate in the buyer's screening process, and an obligation to notify the buyer of any sanctions-related findings before closing. The buyer's OFAC diligence should cover the target's top customers and suppliers, all significant beneficial owners of the target, and any joint venture partners or agents operating in sanctioned jurisdictions.

FCPA Diligence in Inbound Targets

The Foreign Corrupt Practices Act (FCPA) prohibits US persons and US issuers, as well as certain foreign persons acting within US territory, from paying or offering anything of value to foreign government officials to obtain or retain business. An acquiring company can inherit FCPA liability when it acquires a company that has engaged in improper payments, even if those payments predated the acquisition and even if the buyer had no knowledge of them at the time of closing. The DOJ and SEC have made clear through enforcement actions and published guidance that successor liability applies in M&A.

In inbound transactions, FCPA diligence is relevant because many foreign acquirors are themselves subject to the FCPA if they are issuers on US exchanges or if they have US operations or US dollar transactions. More directly relevant, the US target may have foreign operations, foreign sales agents, or foreign government contracts that created FCPA exposure historically. If the buyer is a US company or a company subject to FCPA jurisdiction, it will inherit that exposure at closing. If the buyer is a foreign company not otherwise subject to FCPA, it should still conduct FCPA diligence because the target's US operations and employees will remain subject to the statute post-close.

Effective FCPA diligence in a cross-border transaction covers: the target's operations in high-risk jurisdictions (as ranked by Transparency International's Corruption Perceptions Index or comparable sources); the target's use of foreign sales agents, distributors, and consultants and the due diligence that was conducted on those third parties; the target's government contracting activity and any permits, licenses, or regulatory approvals obtained in jurisdictions with elevated corruption risk; the target's prior FCPA investigations, self-disclosures, or government inquiries; and the target's compliance program, including anti-bribery policies, training, and monitoring.

If diligence reveals FCPA concerns, the buyer faces a choice: price adjust or escrow for the exposure, require the seller to pre-close remediation or self-disclosure, walk away from the transaction, or close with robust indemnification and escrow. DOJ and SEC have encouraged acquirors to conduct thorough pre-acquisition diligence and, where violations are found, to self-disclose promptly post-close. A buyer that inherits an FCPA problem, self-discloses, and remediates promptly is treated more favorably by enforcement authorities than one that closes without diligence or conceals known violations.

Transfer Pricing and Cost-Share Arrangements

Transfer pricing rules govern the prices that related parties charge each other for goods, services, intellectual property licenses, and financial transactions. US transfer pricing rules, codified in IRC Section 482 and extensive Treasury regulations, require that intercompany transactions between a US entity and its foreign affiliates be priced on an arm's-length basis. Transfer pricing is relevant in cross-border M&A both as a diligence matter (the target may have transfer pricing exposure from prior periods) and as a planning matter (the buyer must structure post-close intercompany arrangements in compliance with applicable rules).

From a diligence perspective, the key questions are whether the target has transfer pricing documentation as required under IRC Section 6662, whether the target has any pending or past IRS transfer pricing examinations or adjustments, and whether the target's existing intercompany arrangements were priced on an arm's-length basis. A target that has been operating under intercompany agreements that systematically undercharge or overcharge the US entity may face significant transfer pricing adjustments upon audit, which translate into additional tax liability and potential penalties. The buyer should obtain copies of any transfer pricing studies or intercompany agreements and have tax counsel review them against current arm's-length standards.

Post-close, the buyer must establish new intercompany agreements between the acquired US entity and any foreign affiliates that will have ongoing business relationships with it. Those agreements must cover the pricing of goods sold between affiliates, any management fee or shared service arrangements, the licensing of intellectual property between the US entity and the foreign parent, and any intercompany loans (including the applicable interest rate, which must satisfy IRC Section 1274 or the applicable federal rate rules). Failure to document intercompany transactions contemporaneously is a recurring audit issue and a source of penalties even where the pricing itself is defensible.

Cost-sharing arrangements present a specialized transfer pricing structure relevant to technology-intensive businesses. Under a qualified cost-sharing arrangement (QCSA), a US entity and its foreign affiliate share the costs of developing intellectual property in proportion to their respective anticipated benefits, with the result that each party develops an ownership interest in the IP for its territory. A buyer acquiring a US company that is a participant in a QCSA must understand the structure, its compliance history, and how the acquisition affects each party's platform contribution obligations and platform contributions transaction obligations. Unwinding or restructuring a QCSA at the time of an acquisition can trigger immediate income recognition and requires careful coordination with tax counsel.

Foreign Currency and Hedging at Close

Currency risk in cross-border M&A operates at two levels: the risk that exchange rate movements between signing and closing change the effective purchase price in the seller's or buyer's home currency, and the ongoing risk that the target's earnings are denominated in a currency other than the buyer's reporting currency. Both forms of risk require deliberate management, but the pre-close risk is the more immediately actionable concern for deal counsel and financial advisors.

In a standard cash deal where the purchase price is fixed in US dollars, a foreign buyer bears the risk that the dollar strengthens against its home currency between signing and closing. If the signing-to-closing period is two to three months (which is common for transactions requiring regulatory approval), a 5 to 10 percent currency movement is plausible and can represent a meaningful change in the deal's effective cost. Buyers can hedge this exposure through forward contracts, which lock in a specified exchange rate for a defined future delivery date, or through currency options, which provide the right but not the obligation to exchange at a specified rate. Both instruments are available from major commercial banks, but they involve counterparty credit risk and option premium costs that must be factored into the overall deal economics.

The purchase agreement should address currency risk explicitly. In some cross-border transactions, the parties agree to denominate the purchase price in both currencies with a fixing mechanism tied to a specified exchange rate or rate source. In others, the purchase agreement includes a currency collar that adjusts the dollar-denominated price if the exchange rate moves beyond a specified band before closing. Sellers in these transactions must model the economic effect of the collar under various exchange rate scenarios before agreeing to the mechanism, and buyers must understand the impact on their hedging strategy. Financing for cross-border transactions adds another layer of currency complexity; see how to finance a business acquisition for a treatment of financing structures and their cross-border dimensions.

Post-close, the buyer must manage the acquired entity's ongoing currency exposure. A US business generating revenues in US dollars poses no currency mismatch for a US buyer, but a US business with significant foreign receivables or a foreign cost base (common in companies with offshore manufacturing or development centers) creates an ongoing translation and transaction exposure that must be addressed in the buyer's treasury policy. Integration planning should include an early assessment of the target's existing hedging program, its FX exposure profile, and how the buyer intends to manage consolidated currency risk post-close.

Governing Law, Arbitration, and Enforcement

The choice of governing law in a cross-border purchase agreement is consequential in ways that domestic deals do not require the parties to consider. US M&A agreements are almost universally governed by Delaware or New York law, both of which have well-developed bodies of case law, experienced courts, and predictable outcomes on standard M&A legal questions. When one or both parties are foreign, or when the target has significant foreign assets, the selection of governing law must be deliberate and documented in the agreement with specificity sufficient to withstand a jurisdictional challenge.

Dispute resolution in cross-border transactions often involves a choice between US court litigation and international arbitration. US courts are efficient and their judgments are generally enforceable domestically, but their judgments can be difficult or expensive to enforce in many foreign jurisdictions that have not acceded to bilateral enforcement treaties. International arbitration awards under the New York Convention are enforceable in more than 160 countries and are the preferred dispute resolution mechanism for transactions involving counterparties from jurisdictions where US court judgments are not automatically recognized.

Common international arbitration institutions used in cross-border M&A include the ICC (International Chamber of Commerce), the AAA-ICDR (International Centre for Dispute Resolution), the LCIA (London Court of International Arbitration), and SIAC (Singapore International Arbitration Centre). The choice of institution, seat, number of arbitrators, and procedural rules must be specified in the purchase agreement's arbitration clause. A poorly drafted arbitration clause (for example, one that names an institution but fails to specify procedural rules or that creates ambiguity about whether certain disputes are arbitrable) can result in parallel litigation over the validity of the clause itself before the underlying dispute is even addressed.

The purchase agreement should also address enforcement of representations and warranties insurance in cross-border transactions, which presents additional complexity. A W&R insurer that is a US company may be reluctant to cover a foreign buyer's claims against a foreign seller under a policy governed by foreign law. Parties should confirm with their insurance broker at the diligence stage whether W&R coverage is available for the transaction structure and, if so, on what terms and with what exclusions for cross-border-specific risks.

Document Translations and Dual-Language Execution

In cross-border transactions, the principal transaction documents are typically prepared in English, but local law in the seller's or target's jurisdiction may require that certain documents be in the official language of that jurisdiction or be accompanied by a certified translation. The requirement varies by country: many civil-law jurisdictions require notarization and apostille of corporate documents, translated into the local language by a certified translator. Failing to comply with these formalities can render an otherwise valid transaction document unenforceable in the local jurisdiction, creating a gap in the chain of title that may be difficult or expensive to remedy post-close.

Due diligence in cross-border transactions that involves review of foreign-language documents requires translation of material items into English. The scope of translation should be calibrated to the transaction's risk profile: a target with extensive foreign operations and complex foreign-language contracts may require professional certified translation of key agreements, while a target with minimal foreign-language documentation may be adequately served by counsel's working review of translated summaries. The cost and time required for translation must be built into the diligence budget and timeline from the outset.

Dual-language execution of the purchase agreement itself is sometimes required or requested in transactions where one party is from a jurisdiction that requires local-language documents for regulatory filings or corporate approvals. When a dual-language agreement is executed, the parties must specify which language controls in the event of a conflict. The controlling language should be the one in which the agreement was principally negotiated (typically English) to ensure that the parties' actual intent governs. A dual-language agreement in which the local-language version controls can expose the US party to interpretive risk if the translation does not perfectly capture the English commercial terms.

Foreign corporate approvals are another area requiring attention. A seller or buyer organized under foreign law may require board approval, shareholder approval, or approval from a works council or supervisory board before executing a binding purchase agreement or before closing. The conditions and timing for those approvals must be understood early and reflected in the purchase agreement's conditions to closing and termination rights. A transaction that requires shareholder approval under foreign law may also require compliance with foreign securities disclosure rules, which can impose public announcement obligations before the US parties would otherwise be required to disclose the transaction.

Closing Mechanics Across Time Zones

Closing a cross-border transaction on a single day requires the coordination of multiple parties, financial institutions, and regulatory confirmations across different time zones and business day conventions. A transaction that requires wire transfers in US dollars, euro-denominated payments, and local-currency disbursements in a third country on the same day must account for the cut-off times of multiple payment systems, the business hours of the relevant banks, and the risk that any one transfer fails to complete on schedule.

The standard mechanism for managing this risk is a pre-funded escrow arrangement. The buyer deposits the purchase price with a neutral escrow agent before the closing date, and the escrow agent is authorized to release funds when all closing conditions are confirmed to be satisfied. Pre-funding eliminates the wire timing risk on the day of closing and allows the parties to confirm that funds are available before any documents are released or any regulatory filings are made. The escrow instructions must specify precisely what conditions trigger the release, who confirms satisfaction of those conditions, and what happens if release does not occur by a specified deadline.

Pre-signed document sets are a complementary tool. Counsel for each party prepares and signs all closing documents in advance and holds them in escrow pending the go-ahead from the parties' deal leads. The closing director (typically a senior member of one party's counsel team) calls the close once all conditions are confirmed, releases the documents, and instructs the escrow agent to release funds. This approach allows the parties to achieve a practical simultaneous close even when counsel are in offices separated by twelve or more hours.

The closing memorandum for a cross-border transaction should specify: the agreed closing time in each relevant jurisdiction, the order of operations for document release and wire authorization, the identity of the closing director and their alternates, the bank cut-off times for each currency transfer, the confirmation procedures for each regulatory condition, and the fallback procedures if any element does not complete on schedule. A well-drafted closing memorandum eliminates ambiguity on the day itself and allows counsel to manage the close efficiently even when unexpected issues arise at the last hour.

Post-Closing Integration and Regulatory Compliance

Integration in cross-border transactions is not merely an operational and cultural exercise; it is a continuing legal and regulatory obligation. Where CFIUS has approved a transaction subject to a national security agreement (NSA) or a letter of assurance, the parties have ongoing compliance obligations that are monitored by a government security officer appointed under the agreement. Those obligations may include restricting foreign nationals' access to sensitive facilities or data, maintaining audit logs, filing compliance reports, and promptly notifying CFIUS of material changes to the business. A failure to comply with an NSA can result in civil penalties and, in extreme cases, forced divestiture of the acquired business.

Data privacy is a recurring integration challenge in inbound transactions. If the acquired US business collects personal data from EU data subjects, it is subject to GDPR, and the change of ownership may affect the legal basis on which the data was collected or transferred. The buyer must assess whether the target's data processing activities were conducted under a valid legal basis and whether any required data subject notifications must be made post-close. Transfers of personal data from the EU to the US require one of the recognized transfer mechanisms (Standard Contractual Clauses, the EU-US Data Privacy Framework, or Binding Corporate Rules), and the integration team must ensure those mechanisms are in place before the EU entity begins sharing data with the new US owner.

Tax integration requires establishing new intercompany agreements, filing post-close tax elections, and notifying relevant tax authorities of the change of ownership. In the United States, certain tax elections must be made within a specific period post-closing (for example, a Section 338(h)(10) election in a stock purchase treated as an asset purchase for tax purposes). Missing these deadlines forfeits elections that can have material economic value. Counsel should prepare a post-close legal compliance calendar before closing that identifies every regulatory notification, tax election, and compliance filing required in the weeks and months immediately following the transaction.

Employment integration in cross-border transactions is governed by the law of the jurisdiction where each employee works. In EU jurisdictions, works council consultation obligations may have been triggered by the transaction, and those consultations must be completed in accordance with the applicable national law even if the transaction itself has already closed from a US legal perspective. The buyer's employment counsel in each affected jurisdiction must advise on notification requirements, the treatment of employee benefit plans, and any mandatory severance or change-in-control obligations that arise from the change of ownership.

Reps and Warranties Unique to Cross-Border Transactions

A cross-border purchase agreement includes a set of representations and warranties that do not appear in domestic transactions or that appear in substantially more detailed form. These provisions reflect the additional regulatory exposure, jurisdictional complexity, and counterparty verification challenges that are inherent in transactions involving foreign parties or foreign assets. Buyers and sellers alike must understand the scope and limitations of these representations before agreeing to them.

On the seller side, key cross-border representations include: CFIUS filing compliance or confirmation that no mandatory filing was required; OFAC and sanctions compliance, including representations that no party to the transaction is a designated person or is owned or controlled by a designated person; FCPA compliance and the absence of improper payments to foreign government officials; ITAR compliance, including accuracy of DDTC registration, classification of controlled items, and absence of unauthorized deemed exports; transfer pricing compliance and the arm's-length nature of intercompany transactions; and the validity and enforceability of the agreement under both US law and any applicable foreign law.

Foreign sellers often represent that the transaction does not require any approval under the laws of the seller's home country that has not already been obtained. This representation is material because a failure to obtain a required home-country approval could render the transaction void or unenforceable in the seller's jurisdiction even if it is valid under US law. Buyers should conduct independent diligence on this point rather than relying solely on the seller's representation; the consequences of a void transaction in the seller's jurisdiction can include the buyer's inability to enforce the purchase agreement or the transfer documents in local courts.

Representations and warranties insurance is available for cross-border transactions but with more complexity than for domestic deals. Insurers may exclude CFIUS-related risks (because CFIUS outcomes are unpredictable), OFAC sanctions risks (because the insurer may not be able to provide coverage for transactions that implicate sanctions), and FCPA risks above a defined threshold. The buyer must understand these exclusions before relying on W&R insurance as the primary mechanism for managing seller-side risk. Where the exclusions are material, the buyer may need to retain a larger portion of the purchase price in escrow or negotiate enhanced indemnification provisions. See indemnification provisions in M&A for a structural analysis of how these provisions interact with W&R insurance and other risk allocation mechanisms.

Working with Acquisition Stars

Cross-border M&A transactions require counsel who can manage the full domestic legal framework while simultaneously coordinating the CFIUS, FIRPTA, export control, sanctions, and tax treaty workstreams that are unique to international deals. Those workstreams do not run themselves; they require active management, regulatory expertise, and the ability to synthesize a complex multi-jurisdictional analysis into clear guidance for the client at each stage of the transaction.

Acquisition Stars works with clients on inbound US transactions, including CFIUS filing preparation and strategy, purchase agreement drafting for cross-border deals, FIRPTA compliance and withholding certificate coordination, export control and ITAR diligence, OFAC and FCPA review, and cross-border closing logistics. Alex Lubyansky brings 15 years of M&A transaction experience to each engagement, with direct involvement in each matter from initial structuring through post-close compliance. The firm operates on a relationship model; each client works directly with Alex, not with junior staff rotating through matters.

The firm is based in Novi, Michigan, and serves clients nationally and in cross-border transactions. Acquisition Stars does not position itself as the right counsel for every deal. The firm focuses on transactions where the client values direct attorney engagement, careful analysis over volume throughput, and counsel who can advise on both the legal and strategic dimensions of a complex transaction. Cross-border M&A, with its layered regulatory requirements and deal-specific structuring challenges, is exactly the type of matter where that approach produces the best outcome for the client.

For buyers, sellers, or their advisors evaluating an inbound US transaction and looking for legal counsel with cross-border M&A depth, the starting point is a conversation about the transaction's specific profile. Acquisition Stars can be reached at 248-266-2790 or consult@acquisitionstars.com. The firm is located at 26203 Novi Road Suite 200, Novi MI 48375.
