Work highlights

Acting as lead Thailand counsel to COSCO SHIPPING Ports — one of the world's leading global port operators — in the acquisition of minority equity interests in two of Thailand's most strategically critical maritime assets: a 12.5% stake in Thai Laemchabang Terminal and a 30% stake in Hutchison Laemchabang Terminal, both located at Laem Chabang Port, for a total consideration of approximately $110 million. Together, these two terminals are the largest operators at Laem Chabang Port, Thailand's premier deep-water container hub, which accounts for approximately 80% of the country's total container throughput. The firm provided comprehensive legal support across the transaction, including due diligence on both terminals and related companies, preparation of transaction documents, and advice on all Thai law aspects of the acquisition, working in coordination with Holman Fenwick Willan as instructing firm in Hong Kong. The deal reinforces COSCO SHIPPING Ports' strategic footprint in Southeast Asia and strengthens synergies between its port operations and its dual-brand shipping services in the region.

Acting as sole lead Thai counsel to DRS Investment SE — a prominent German private equity firm — in connection with its strategic acquisition of a controlling interest in the newly formed Factory Group, created through a merger of Germany's Vignold Group and Swiss marketing service provider The Factory. The transaction marked a significant strategic pivot for DRS Investment SE, expanding its investment focus from traditional software companies toward tech-enabled services, with the Factory Group pioneering AI-enhanced, large-scale marketing asset production across more than 150 specialists in six countries, including a key production hub in Thailand. The firm conducted legal due diligence on the Thai subsidiaries of Vignold Group and advised on the post-acquisition restructuring of those subsidiaries, navigating complex Thai regulatory frameworks to ensure seamless alignment with the client's broader international transaction structure. The deal was coordinated internationally by Massing Werner, with the firm serving as the exclusive advisor on all Thai law matters.
