(Yicai Global) Dec. 3 -- Advanced Semiconductor Engineering Technology Holding, the world’s largest semiconductor packaging and testing company, plans to sell its plants in the Chinese mainland to private equity firm Wise Road Capital for USD1.46 billion.

Wise Road will buy four plants, one each in Weihai, Suzhou, Kunshan, and Shanghai, ASE said in a statement on Dec. 1. Beijing-based Wise Road will pay USD1.08 billion on the completion date and USD380 million on the first business day six months after completion.

The factories turn out products used in the fields of analog, digital-analog hybrid, power devices, and radiofrequency. After the sale, only ASE’s unit Siliconware Precision Industries will have packaging and testing businesses in the mainland.

The deal will improve ASE's overall competitive edge by optimizing its strategy and resource allocation in China, while further enhancing its investment in advanced technology development and expanding its leading-edge capacities within Taiwan, the Taiwan-based firm said.

Wise Road is a well-known investor in the semiconductor field in China. It has participated in many mergers and acquisitions in the industry. With Beijing Jianguang Asset Management in 2016, it bought NXP Semiconductors’ unit Nexperia for USD2.75 billion.
