While Q2 FY26 results are due later this month, the sales numbers already point to healthy growth. For May and June, net sales increased by 17.78% and 22.85%, respectively, year-over-year (YOY). As a semiconductor foundry, the company seems well positioned for sustained growth.
Of course, this is not the only positive news. Recently, the company announced its first mass-produced silicon photonics wafers within the Singapore facility. With silicon photonics capabilities, the company aims to address the “demand for high-speed optical interconnects in AI and hyperscaler data center networks.” UMC is also planning to “own 12-inch silicon photonics platform available for customer product development in 2027.”
This is an important milestone for the company from the perspective of innovation and catering to the future demand. UMC stock remains attractive even after a meaningful rally.

In June 2026, Fitch affirmed BBB+ rating for United Microelectronics with a “Stable” outlook. The rating agency believes that the company’s profitability and cash flow will improve over the coming years. This is likely to be backed by “gradual recovery in demand across its addressable markets, firmer utilization, tighter eight-inch foundry supply and improving pricing conditions.”
At the same time, innovation is likely to play an important role in the margin expansion story. With factors of contribution from advanced packaging and silicon photonics. These factors will translate into lower leverage and an increase in cash buffer for investments and shareholder returns.
