Franco-Italian chipmaker STMicroelectronics beat analyst expectations in its STMicroelectronics Q3 earnings on Thursday, posting an operating profit of $429 million. The company credited expanding shipments to artificial intelligence data centres and satellite operators for lifting sales above market forecasts after a prolonged slump across the semiconductor industry.
Key points
- Operating income reached $429 million before one-off charges, up nearly twofold from a year earlier.
- Third-quarter revenue hit $3.76 billion, with gross margin rising four percentage points to 37.3%.
- Fourth-quarter revenue is forecast at $4.15 billion, exceeding analyst projections compiled by LSEG and Bloomberg.
- AI data centre components and low-Earth-orbit satellite hardware drove growth alongside broader industrial demand.
Third-quarter performance and margin gains
STMicroelectronics reported operating profit excluding one-off charges of $429 million for the quarter ended 30 September. That beat the consensus estimate of $400.5 million from an analyst survey by LSEG. The result represented a near doubling of operating income compared with the third quarter of last year.
Revenue for the quarter reached $3.76 billion, led by higher sales of communication equipment, personal electronics and computer peripherals. The company, which supplies key components to Apple and Tesla, produces microcontrollers, imaging sensors and power semiconductors used across automotive and consumer hardware.
Profitability improved across the manufacturing footprint. Gross margin climbed to 37.3% from 33.2% a year earlier. STMicroelectronics attributed the margin expansion to a richer product mix featuring more profitable silicon components, paired with reduced costs from previously idle factory lines.
Data centres and satellites drive growth
The company benefited from specialized demand channels that outpaced standard cyclical replacements. While carmakers and consumer device brands had slowed orders over previous quarters, server infrastructure spending provided fresh momentum.
Chief executive Jean-Marc Chery said company-specific factors helped lift results above the wider market recovery. The rapid expansion of AI computing facilities created sustained demand for power management chips and interface hardware. At the same time, builders of low-Earth-orbit satellite constellations expanded orders for communications semiconductors.
“In an environment where demand remains well above supply, we continue to expand capacity aligned with ST’s strategic roadmap,” Chery said in the earnings statement.
Analysts at Jefferies said that STMicroelectronics appears positioned to carry that momentum forward. The brokerage expects the company’s data centre sales to roughly double from this year into 2027, creating additional margin support over the next twelve months.
Fourth-quarter outlook and market recovery
Looking ahead, STMicroelectronics projected fourth-quarter revenue of $4.15 billion, plus or minus 3.5%. The guidance beat average analyst forecasts, which stood at $4.10 billion in LSEG data and $4.11 billion in Bloomberg surveys.
Management had indicated in July that fourth-quarter turnover would top $4 billion, but Thursday’s guidance provided a firmer midpoint. The company expects fourth-quarter gross margin to expand further to approximately 39% as manufacturing capacity utilization continues to increase.
The upgraded forecast signals broader stability for European semiconductor producers following two years of inventory corrections. STMicroelectronics plans to maintain capital investment in specialized manufacturing lines to meet ongoing delivery commitments for server and communications customers through 2027.
