The Korean antitrust regulator has requested additional information from US-listed semiconductor companies Skyworks Solutions and Qorvo as part of an extensive review of their USD 10.1bn cash and share deal, an official at the regulator told this news service.

The comment comes after the communications specialist chip suppliers confirmed in December they had filed notification of their deal with the Korea Financial Trade Commission, China and Taiwan. Skyworks’ recommended stock and cash acquisition of domestic peer Qorvo was announced on 28 October.
