STMicroelectronics shares surge 6.58% after-hours after unveiling next-gen STM32V8 MCU with SpaceX adoption and radiation-hardened LEO diode expansion.

STMicroelectronics surged 6.58% in after-hours trading following the launch of its STM32V8 microcontroller, a next-generation high-performance chip designed for industrial automation and edge AI applications. The product, featuring an 800MHz Arm Cortex-M885 core and 18nm FD-SOI technology, positions the company as a leader in advanced embedded systems, with early adoption by SpaceX for inter-satellite laser communications. Additionally, the expansion of radiation-hardened low-voltage rectifier diodes for Low Earth Orbit satellites underscored ST’s strategic focus on the growing New Space industry, enhancing its competitive edge. Market sentiment was further bolstered by broader European risk appetite, as Milan’s Piazza Affari index rose amid optimism over U.S. semiconductor deals and potential Fed rate cuts. These developments collectively reinforced investor confidence in STMicroelectronics’ innovation and market positioning.
