On June 15, UMC rose 4.16% in pre-market trading, trading at $22.26/share, with turnover of $181,600, extending its recent rebound momentum.

On the news front, the semiconductor sector continued to strengthen broadly, with Micron Technology up 6.4%, Marvell Technology up 5.43%, AMD up 4.61%, and Intel up 3.43%, maintaining positive sector sentiment. On the fundamental side, UMC's embedded Deep Trench Capacitor (DTC) technology has successfully entered Qualcomm's supply chain with shipments already underway, marking a significant milestone in advanced packaging. DTC technology embeds high-density capacitors within silicon interposers or advanced packaging substrates, significantly shortening power delivery paths and reducing parasitic effects — a critical solution for AI chips with rapidly escalating power demands.

Additionally, UMC reported Q1 net profit surging 108% year-over-year to NT$16.17 billion, with May revenue growing 17.8% YoY to NT$22.94 billion. The company has also confirmed selective price hikes of approximately 10% in the second half, providing sustained earnings growth momentum. After a prior cumulative pullback exceeding 15% on elevated valuations, these multiple catalysts have attracted capital inflows.
