United Microelectronics (UMC) reported second-quarter 2026 revenue of approximately NT$69 billion. This figure represents a 13% sequential increase and a 17% year-over-year gain. The results exceeded analyst estimates.
Strong demand from the communications, computer, and consumer electronics sectors drove the robust performance.
UMC stock fell as much as 8% following the announcement. This decline occurred despite the company's positive financial results.
A broader semiconductor industry selloff triggered the stock's drop. Investors engaged in profit-taking amid concerns over high valuations. Market sentiment also weakened after Samsung's earnings failed to impress the industry.
