STMicroelectronics (NL0000226223) closed at EUR 50.34 on Euronext Paris on October 2, 2026, up 6.54 percent for the session. The move followed renewed attention to AI infrastructure demand, while the company entered the final quarter with stronger quarterly growth and higher data-center ambitions.

AI demand lifts quarterly results

STMicroelectronics reported Q2 2026 revenue of USD 3.49 billion on July 23, 2026, up 26 percent year over year. Gross margin was 34.8 percent, while net income reached USD 222 million compared with a USD 97 million loss in Q2 2025.

The quarter also delivered a measurable expectations beat. According to MarketBeat on October 2, 2026, adjusted EPS was USD 0.31 against USD 0.26 consensus, while revenue of USD 3.49 billion exceeded the USD 3.46 billion estimate.

Guidance points to stronger second half

Management expects Q3 2026 revenue of USD 3.70 billion at the midpoint, representing 6.2 percent sequential growth and 16.2 percent year-over-year growth, according to the company earnings-call transcript published by Yahoo Finance. Q4 revenue is expected to exceed USD 4 billion, with AI data centers and low-earth-orbit satellite communication identified as key growth areas.

The valuation leaves execution as the central test. MarketScreener reported on September 14, 2026, that UBS maintained its Buy rating and an EUR 80 price target. That target stands EUR 29.66 above the October 2 closing price, leaving the market focused on whether margins and data-center revenue can meet the guidance.
