Sweden Silex acquired 100 percent of Corem Science Fastighets AB (now renamed "Silex Properties AB") held by Corem Stockholm Holding AB for 0.294 billion Swedish kronor. Recently, Silex Properties AB has completed the registration procedures for industrial and commercial changes in the Swedish Company Registration Office and received a new registration certificate. Silex Properties AB has become a wholly-owned subsidiary of the company indirectly holding 100 percent of the shares through its wholly-owned overseas subsidiary, namely Silex of Sweden.
Silex Properties AB holds a land area of 43,771 square meters and a building area of 19,270 square meters. It is a complete semiconductor manufacturing park, part of which is the production and business premises currently leased by Silex in Sweden. At this stage, the company has maintained a very stable state in all aspects of the office and personnel for a long time, based on the company's long-term development strategy of establishing both domestic and overseas contract manufacturing service systems, Silex Securities AB, a wholly-owned subsidiary of Sweden's wholly-owned subsidiary Silex, can provide predictable realistic conditions for the company's MEMS process development and the expansion and development of wafer manufacturing business in Sweden by acquiring 100 percent equity of Silex Properties AB and holding its existing assets such as land and buildings on the ground. This transaction is in line with the company's development strategy and business development needs, and is conducive to the sustainable development of the Swedish subsidiary's business, thereby promoting the further development of the company's overall business and improving the company's overall competitiveness on a global scale.
