On October 13, United Microelectronics fell 3.1% overnight, trading at $21.89/share, with turnover of $602,100.

The decline is directly linked to the company's recently announced $1.8 billion dual-tranche convertible bond offering, which has heightened market concerns over equity dilution upon conversion. The financing follows a completed $150 million convertible bond issuance in September, which triggered a single-day drop of 5.28% at that time. The current offering is significantly larger in scale, further reinforcing expectations of share dilution and tighter liquidity conditions.

Despite United Microelectronics reporting September revenue of NT$25.35 billion, up 27.22% year-over-year, indicating solid fundamentals, short-term equity expansion pressure continues to dominate market sentiment.

United Microelectronics Corporation operates as a semiconductor wafer foundry in Taiwan, Singapore, China, Hong Kong, Japan, the United States, Europe, and internationally. The company provides circuit design, mask tooling, wafer fabrication, and assembly and testing services. It serves fabless design companies and integrated device manufacturers.
