Infineon Technologies stock was trading at EUR 60.07 at Lang & Schwarz on October 9, 2026 at 12:27 p.m. CEST, up 2.67 percent. The company completed its acquisition of C2i Semiconductors on October 5, 2026, according to Infineon.

AI power deal adds digital expertise

The C2i transaction brings software-defined multiphase controllers, smart power stages and system-level power architecture expertise into Infineon's Power Systems division. The official release says Infineon employs 2,800 people across India, giving the acquisition a concrete engineering base in a market central to the transaction.

The strategic logic is tied to faster-changing loads in AI servers. Combining digital control with silicon, silicon carbide and gallium nitride technologies gives Infineon a broader route from grid equipment to high-performance computing power delivery.

Three portfolio moves with figures

On September 9, 2026, Infineon and SolarEdge extended their cooperation around 800 VDC solid-state protection for AI data centers, as Infineon reported. On September 16, 2026, the company agreed to sell its NOR Flash and F-RAM business to Winbond for USD 1.12 billion, according to Infineon. The October 5 C2i completion is the latest of the three moves.

What does the operating trend show?

In the third quarter of fiscal 2026, revenue rose 9.00 percent from the prior quarter to EUR 4.17 billion, while the segment result reached EUR 797.00 million and the segment margin was 19.10 percent, according to FinanzNachrichten. The revenue progression and margin level make power systems the key operating measure alongside the AI data-center expansion.

At EUR 60.07, the stock stood 32.38 percent below its EUR 88.83 52-week high as of October 9, 2026. That gap leaves the market focused on whether the AI-power strategy can translate into sustained earnings growth rather than only portfolio activity.

Next results date is November 10

UBS kept its Neutral rating and EUR 64.00 price target in a note dated September 25, 2026, while pointing to Infineon's results on November 10, according to FinanzNachrichten. The next report will therefore test whether the third-quarter revenue increase and 19.10 percent margin can support the valuation case.
