ASE Technology's (TPE:3711) unit ASE Test will launch a tender offer to acquire up to a 12.4% stake in Advanced Microelectronic Products (TWO:6287) shares at NT$9 per share.
The move follows Advanced Microelectronic Products' delisting from the OTC market as it aims to reorganize its operations.
The offer will be open from May 15 to June 24, according to a Monday Taiwan Exchange filing.
ASE Test will fund the deal using internal cash, it added.
