On July 29, United Microelectronics fell 10.02% in pre-market trading, trading at $16.70/share, with turnover of $85,900.
On the news front, the global semiconductor sector remains under heavy selling pressure following a systemic selloff driven by AI bubble concerns. South Korea's KOSPI index previously plunged 9.6% triggering a 20-minute trading halt, with Samsung Electronics and SK Hynix both falling over 11%. The contagion spread across the full semiconductor supply chain, with United Microelectronics having already dropped over 11% intraday in the prior session. NVIDIA's new round of transactions exceeding $750 billion further intensified market fears that AI demand may be artificially inflated.
Adding to the pressure, United Microelectronics is set to release its Q2 earnings today. Market consensus expects quarterly revenue of $2.044 billion, up 9.28% year-over-year, with adjusted EPS of $0.15. The company recently commenced silicon photonics chip mass production at its Singapore fab in partnership with Silith Technology, while its 12nm collaboration with Intel has entered the verification phase.
