On September 3, United Microelectronics declined 3.36% overnight, trading at $19.3 per share, with turnover of $395,000.

The decline was primarily driven by persistent equity dilution concerns tied to the company's convertible bond programs. United Microelectronics recently completed a domestic unsecured convertible bond issuance raising NT$47.9 billion (approximately $150 million), with all subscription proceeds received and transferred to the designated account. Additionally, the board had previously approved the issuance of up to $1.8 billion in unsecured overseas convertible bonds in two tranches with a maximum five-year tenor and a tentative 0% coupon rate. The zero-coupon structure means investor returns depend entirely on share conversion, amplifying potential dilution pressure. Proceeds are earmarked for machinery procurement and factory construction.

On the fundamental side, United Microelectronics reported Q2 EPS of $0.54, beating the consensus estimate of $0.15 by 260%. July revenue rose 19% year-over-year to NT$23.84 billion, with mature-node order momentum continuing to improve, supported by demand from power management and sensor products.
