Navigating cross-border M&A in ASEAN markets

Cross-border mergers and acquisitions in Southeast Asia require a level of jurisdictional awareness that many US-based acquirers underestimate. Each ASEAN member state maintains distinct foreign investment frameworks, corporate governance requirements, and sector-specific regulations that can materially affect deal structure, timeline, and economics.

Indonesia’s negative investment list, Vietnam’s conditional business lines, Thailand’s Foreign Business Act, and Singapore’s relatively open but tightly governed corporate regime each present unique considerations. Acquirers who rely on a single legal framework or attempt to apply US deal conventions across the region frequently encounter delays, restructuring requirements, or post-close compliance issues.

Structuring for Success

The most effective cross-border transactions in ASEAN begin with structure. Holding company jurisdiction, intellectual property domicile, and operational entity organization all affect tax efficiency, regulatory approval timelines, and ongoing compliance burden. Singapore remains the preferred holding company jurisdiction for most technology transactions, offering treaty network advantages and regulatory predictability.

Due Diligence Differences

Technology due diligence in Southeast Asia requires attention to infrastructure dependencies, data localization requirements, and licensing regimes that differ from US norms. Financial due diligence must account for varying accounting standards, related-party transaction practices, and currency controls that affect repatriation of proceeds.

Integration Planning

Post-merger integration in a cross-border context demands cultural sensitivity and operational pragmatism. Successful acquirers retain local management teams, invest in compliance infrastructure, and allow integration timelines that account for the practical realities of operating across multiple regulatory environments. Rushed integration destroys value; disciplined, phased approaches preserve it.
