ASE Technology (TPE:3711) priced its $1 billion first unsecured overseas convertible bond offering of 2026 at 100% of par value, with the bonds set to be issued on Aug. 10, according to a Monday Taiwan Exchange filing.
Shares fell 6% in Tuesday's afternoon trade.
The zero-coupon bonds will mature on Aug. 10, 2031, and carry an initial conversion price of NT$927.20 per share.
Proceeds will be used to subscribe for new shares in subsidiaries, Advanced Semiconductor Engineering and Siliconware Precision Industries, through cash capital increases, helping fund the units' repayment of bank borrowings and foreign-currency material purchases.
ASE Technology said full conversion of the bonds would result in a share dilution effect of about 0.78%, which it expects to have a limited impact on existing shareholders' rights.
