Soitec and STMicroelectronics, two French semiconductor heavyweights, continue to post lackluster financial results. Yet industry analysts covering both companies are striking an increasingly optimistic tone. The reversal in sentiment stems from a strategic pivot long demanded by investors: both firms are finally positioning themselves to capitalize on the artificial intelligence boom—not by designing AI processors themselves, but by tackling one of the sector’s most pressing physical constraints, the soaring electricity consumption of data centers.

For several quarters, Soitec and STMicroelectronics were criticized for missing the AI wave, focusing instead on traditional automotive, industrial, and communications end markets. That narrative is now shifting. Executives at both companies have signaled that their advanced materials and chip technologies can play a central role in improving energy efficiency across the AI infrastructure stack. Soitec’s engineered substrates, particularly its silicon-on-insulator (SOI) wafers, enable transistors to switch faster and leak less current, directly cutting power usage in high-performance computing environments. STMicroelectronics, meanwhile, is leveraging its expertise in wide-bandgap semiconductors—such as silicon carbide (SiC) and gallium nitride (GaN)—as well as energy-efficient microcontrollers and power management ICs, all of which are critical to reducing losses in server power supplies and voltage regulators.

The addressable opportunity is enormous. Data center power demand is projected to double by 2030, fueled by the exponential growth of AI training and inference workloads. Hyperscalers and enterprises alike are under pressure to decouple compute growth from energy consumption, creating a fast-growing market for components that can deliver performance without proportional power increases. Even if Soitec and STMicro are not directly selling AI accelerators, their technologies are becoming essential enablers behind more sustainable data center design.

While revenue and margin figures remain under pressure from inventory corrections and softening demand in legacy segments, the strategic repositioning is giving analysts confidence that these companies are finally aligned with long-term secular trends. If the promised energy-efficiency gains translate into design wins and volume orders, the current financial trough could mark a turning point. The wind, it seems, is at last blowing in their direction.

Malgré des résultats toujours en berne, les analystes des deux fabricants de semi-conducteurs restent optimistes. Car si ces derniers étaient épinglés pour ne pas avoir pris le virage des processeurs IA, le vent pourrait bien être en train de tourner.
