The artificial intelligence spending wave is creating winners far beyond the companies building headline-grabbing AI processors. On Tuesday, semiconductor manufacturer STMicroelectronics sharply increased its revenue targets for its data-center business, signaling that demand for the infrastructure supporting AI systems continues to accelerate at a pace faster than many industry observers anticipated.
Investors welcomed the announcement. Shares of the Franco-Italian chipmaker climbed as much as 10% to €65.21, their highest level since September 2000, before settling slightly lower. The stock remained among the strongest performers on Europe’s benchmark STOXX 600 index, reflecting growing confidence that STMicroelectronics is becoming a significant beneficiary of the global AI investment cycle.
The company now expects its data-center business to generate approximately $1 billion in revenue in 2026, a substantial increase from its previous forecast of revenue “nicely above” $500 million. Even more striking was management’s outlook for 2027.

“Assuming the current dynamic continues and with the current engagements we have, revenues could double in 2027,” the company said.
That projection effectively raises STMicro’s 2027 ambitions from its earlier expectation of revenue “well above $1 billion” and points to a business that could become one of the company’s fastest-growing segments over the next several years.
The upgraded guidance highlights an increasingly important reality in the AI era: while companies such as Nvidia dominate attention because of their graphics processing units, a vast ecosystem of semiconductor firms is benefiting from the massive infrastructure required to support AI computing.
Unlike Nvidia and other companies focused on AI accelerators, STMicroelectronics’ exposure lies primarily in the hardware surrounding those processors. Its products are used in power management systems, energy conversion equipment, industrial electronics, and other critical components that help data centers operate efficiently.
As hyperscale cloud providers and technology companies spend hundreds of billions of dollars building AI infrastructure, demand is rising not only for computing chips but also for the supporting technologies that distribute power, manage heat, and ensure reliable operation of increasingly energy-intensive facilities.
The scale of that opportunity is enormous. Global technology giants, including Microsoft, Amazon, Alphabet, Meta, and Oracle, are collectively committing unprecedented amounts of capital to AI infrastructure. Industry forecasts suggest annual spending on AI-related data centers could approach $1 trillion within the next few years.
That spending boom is creating opportunities for suppliers throughout the semiconductor value chain. For STMicroelectronics, the upgraded forecast is being driven by two factors: stronger-than-expected customer demand and progress in expanding manufacturing capacity.
The company said its improved outlook reflects both the continued surge in AI-related infrastructure spending and advances in ramping production capabilities to meet future orders. Capacity expansion has become a critical competitive advantage in the semiconductor industry as customers seek assurance that suppliers can meet long-term demand.
Analysts believe the guidance upgrade could lead to meaningful revisions in earnings expectations.
According to analysts at Jefferies, the data-center business alone could contribute approximately 7% growth to STMicro’s revenue in 2027, representing a substantial portion of their overall forecast of 20.5% growth for the company that year.
Analysts at J.P. Morgan reached a similar conclusion.
“The new guidance on AI likely results in estimates rising in both years though we would think that estimates will rise more in 2027 than in 2026,” the bank said in a research note.
The market reaction suggests investors view STMicroelectronics as more than a traditional industrial semiconductor company. Instead, it is becoming part of the broader AI infrastructure story that has propelled valuations across the technology sector.
That transformation is good news for European technology companies. While the United States dominates AI software and advanced processor development, European firms have often struggled to establish leading positions in the most lucrative segments of the technology industry.
STMicro’s growing role in AI infrastructure offers a different path to capturing value from the AI revolution. Rather than competing directly with Nvidia, AMD, or other AI chip designers, the company is supplying the essential components that enable AI data centers to function.
Early enthusiasm around AI focused largely on the chips used to train and run models. Increasingly, attention is turning toward the infrastructure ecosystem required to support those chips, including networking equipment, power systems, cooling technologies, and semiconductor components.
As AI models become larger and more energy-intensive, those supporting technologies are emerging as critical bottlenecks and significant profit opportunities.
For STMicroelectronics, Tuesday’s upgraded targets suggest management believes the current AI investment cycle remains in its early stages. If hyperscale spending continues at its current pace, the company’s data-center business could become a major growth engine and an increasingly important contributor to earnings over the remainder of the decade.
The sharp rally in the stock indicates investors are beginning to price in that possibility.
