A Beijing-listed medical technology company planned to acquire the renal replacement therapy business unit of a well-known European company. This business involved production bases in five countries, including Germany and Spain, as well as a global supply and distribution network. The transaction structure was complex and required compliance with regulatory requirements in multiple countries. Caichen Fuwo assembled a dedicated legal team and coordinated with partner law firms in China and Europe to provide comprehensive services throughout the entire process. These included conducting a global legal due diligence investigation through nearly 100 cross-border meetings, identifying IP ownership flaws and antitrust risks in the target assets. The firm optimized the transaction structure twice to address EU FDI review requirements, designing a combined "equity acquisition + asset divestiture" solution. The firm participated in the entire M&A agreement negotiation process, focusing on clarifying the transfer of overseas employee employment relations and global intellectual property licensing terms. Ultimately, the client completed the transaction for 420 million yuan, providing critical legal support for the implementation of its internationalization strategy. This experience has been recognized as a case study by an industry association.
