(“Zhizheng”, stock code: 603991.SH), a company listed on the Main Board of the Shanghai Stock Exchange, Zhizheng acquired equity interests in Advanced Assembly Materials International Limited (“AAMI”) through a combination of share issuance, cash consideration, material asset swap and other transaction structures.

Zhizheng acquired 49% of the equity interests in AAMI held by ASMPT Hong Kong Holding Limited, a wholly-owned subsidiary of ASMPT (the “ASMPT Subsidiary”), through the issuance of shares and payment of cash consideration. In addition, Zhizheng acquired approximately 38.47% of the equity interests in AAMI held by ten other transaction counterparties through a combination of material asset swap, share issuance and cash consideration. Meanwhile, AAMI repurchased approximately 12.49% of its equity interests held by Hong Kong Zhixin.

  • This transaction represents the first foreign strategic investment project involving a cross-border share swap following the implementation of the Measures for the Administration of Strategic Investment in Listed Companies by Foreign Investors (2024), and is also a market-oriented cross-border M&A transaction jointly led by a private A-share listed company and a Hong Kong-listed company.
  • The transaction serves as a pioneering example of an A-share listed company introducing a global semiconductor industry leader as a strategic shareholder with deep participation in corporate governance, and will strongly promote international cooperation and synergistic development within the domestic and overseas semiconductor industries.
  • The transaction breaks new ground in the A-share market, guiding more high-quality foreign investors to enter China’s capital markets for long-term investment, opening up a new pathway for A-share listed companies to acquire high-quality overseas non-listed assets, and providing foreign investors with more diversified options to restructure and optimize their investments in China.
  • The transaction involves multiple transaction structures, including cross-border share swaps, domestic share swaps, cash consideration, material asset swaps and cash repurchase by the target company, fully accommodating the diverse commercial objectives of the parties.
  • No performance compensation arrangement was included in this transaction. Instead, impairment compensation is provided solely by transaction counterparties controlled by Zhizheng’s controlling shareholder, demonstrating China’s continued efforts to deepen financial opening-up.

The transaction has been selected as a representative M&A and restructuring case by the Shenzhen Bureau of the China Securities Regulatory Commission in its Listed Company Regulatory Newsletter (2025, Issue No. 2), and has also been included in the Shanghai Stock Exchange’s Compilation of Typical Cross-Border M&A Cases of Listed Companies.
