STMicroelectronics has delivered a third-quarter performance that beat market expectations, nearly doubling its adjusted operating profit and issuing fourth-quarter guidance that exceeds analyst forecasts, as demand from AI data centers and satellite operators fuels a broader recovery in chip markets .

The Franco-Italian chipmaker reported adjusted operating income of $429 million for the quarter, a 98% increase from a year earlier and above the $400.5 million consensus estimate compiled by LSEG. Net revenues rose 17.9% year-over-year to $3.757 billion, slightly ahead of both company guidance and analyst expectations.

"In an environment where demand remains well above supply, we continue to expand our capacity in line with ST's strategic roadmap," said CEO Jean-Marc Chery in the results statement.

The Q4 Outlook

For the fourth quarter, STMicro expects net revenues of $4.15 billion at the midpoint, an increase of 10.5% sequentially and above the $4.11 billion average analyst estimate. Gross margin is projected at 39.0%, up from 37.3% in the third quarter.

The guidance signals that the chip demand recovery that began earlier this year is accelerating. STMicro had previously refrained from providing detailed annual guidance, but with the final quarter approaching, the company now expects full-year revenue to grow nearly 23% to roughly $14.5 billion.

AI and Satellites Drive Growth

The company singled out data centers and satellites as key drivers for the year. STMicro projects data center revenue above $1 billion in 2026 and well above $2 billion in 2027, marking the second time it has raised its AI forecasts this year. It also expects well above $3 billion in revenue between 2026 and 2028 from supplying equipment for low-Earth-orbit satellite constellations, excluding potential benefits from orbital data centers.

The diversification is significant for a company that has long relied on automotive customers. The auto industry's slow digestion of pandemic-era chip inventories had weighed on STMicro's orders, but AI and space are now providing new revenue streams.

What's Next?

STMicro's shares have nearly doubled in value since the start of the year, riding the broader AI-driven semiconductor rally. The company will need to deliver on its Q4 guidance to justify that momentum, particularly as investors remain cautious about the sustainability of AI infrastructure spending and competition from Chinese chipmakers.

Here is the question The Silicon Review raises. STMicro has nearly doubled its profit and raised its Q4 outlook on the promise of AI and satellites, but the company's full-year revenue growth is still modest by semiconductor standards. When a chipmaker beats expectations by diversifying away from its traditional auto market, does that signal a genuine transformation or just a well-timed pivot while the old business recovers?
