STMicroelectronics posts $3.76B Q3 revenue on AI, satellite demand

The European chipmaker beat its guidance midpoint and raised its full-year outlook as AI data centers and LEO satellites drove a 64% jump in one segment STMicroelectronics reported third-quarter 2026 net revenues of $3.76 billion on October 29, a 17.9% increase from a year earlier. The result landed above the midpoint of the company’s own forecast. The headline growth figure is solid. The more interesting number sits inside one segment that grew 64%, powered by two of the hottest buildouts in tech: AI data centers and low Earth orbit satellite networks. Inside the quarter The standout was ST’s communication equipment and computer peripherals segment, which the company abbreviates as CECP. Sales there rose 64% year over year. Two product lines did most of the lifting. One was silicon photonics integrated circuits sold into AI data centers. The other was hardware for LEO satellite programs. Silicon photonics deserves a quick explainer. Think of it as swapping copper wiring for fiber optics, but at the scale of a chip. Instead of pushing data through electrical signals, these components move it with light. That matters because AI clusters shuttle enormous volumes of data between proce...
