International M&A Stock Purchase Agreement Review: Guide to Cross-Border Deals

The SPA must specify which jurisdiction's law controls the contract and which forum hears disputes. An agreement that names New York law but leaves the arbitration seat or procedural rules ambiguous creates conflicts that benefit neither party. Courts have declined to enforce arbitration clauses in international deals where the scope of arbitrable claims was unclear.

Cross-border SPAs often involve multi-currency wiring, third-country escrow accounts, or deferred consideration tied to post-closing milestones. Exchange rate movement between signing and closing can materially affect deal value, and review of hedging arrangements belongs in the SPA review itself.

Closing conditions in cross-border deals require regulatory approvals from two or more jurisdictions, each with its own timeline and review standard. A deal that clears U.S. .ntitrust review may still be pending foreign investment approval elsewhere, and the sequencing of those conditions requires planning from the outset.

The target may hold licenses in multiple countries. Depending on the industry, a change of control triggered by the stock purchase may require re-application or foreign regulatory approval before closing. Healthcare, financial services, and defense-related targets each carry distinct licensing obligations that can affect deal timing.

Cross-border stock purchases frequently raise withholding tax issues on dividends and capital gains. Tax treaty availability between the buyer's and seller's jurisdictions affects whether an intermediate holding company makes sense and where it should sit. These exposures are best identified early, before the deal structure is locked.

In a cross-border deal, representations and warranties must reflect the target's position under each applicable legal system. A representation that the company is "in compliance with applicable law" is only as useful as the underlying definition of what laws apply. Buyers should confirm that seller-proposed qualifiers do not eliminate coverage for risks specific to foreign operations.

Indemnification Claims are a frequent source of post-closing disputes in cross-border deals. The seller may hold no U.S. assets after closing, and cross-border judgment enforcement is not guaranteed. Escrow arrangements are a standard tool for securing indemnification obligations, and the escrow amount, release schedule, and choice of escrow agent are all negotiated points.

MAC clauses in international transactions need to account for events that affect the target's home market specifically. A clause that carves out general economic conditions may inadvertently exclude events that are global in origin but significant for the target's particular market.

CFIUS filings are mandatory for certain transactions involving U.S. .usinesses in technology, critical infrastructure, and data-sensitive sectors, and for transactions involving buyers from countries of concern designated under FIRRMA. Failure to file where required can result in civil penalties and a forced unwind. Even where a mandatory filing is not required, a voluntary notice is often worth submitting to obtain clearance and reduce the risk of a post-closing review.

International transactions often require foreign direct investment review in the target's home country and in other markets where the target operates. The Foreign Investment Review process in the European Union, the United Kingdom, and several Asian jurisdictions each follows its own timeline and substantive standard. Coordinating those parallel processes while managing the overall deal schedule is a core part of cross-border SPA practice.

Transactions above certain thresholds require competition law clearance in addition to national security review. Where the parties operate in multiple markets, filings may be required under the Hart-Scott-Rodino Act in the United States and separately in the EU, the UK, or other jurisdictions. Antitrust and Competition Law review runs on a separate track from CFIUS, and both processes must be coordinated carefully to avoid timeline conflicts at closing.

Buyers acquiring companies in markets where they have limited prior experience frequently discover compliance gaps after closing that due diligence should have caught. Employment obligations, data privacy requirements, and product approval regimes vary significantly across jurisdictions and can create material post-closing liabilities.

The SPA itself shapes post-closing obligations. Transition services agreements, employee retention arrangements, and non-compete provisions all need to reflect the operational realities of both parties. A post-closing integration structure that is enforceable in one jurisdiction may not hold in another.
