Infineon's 800-Volt Pivot: Funding an AI Power Franchise With a Memory Divestment
Published on 09/26/2026 at 14:51 | Editorial boerse-global.de
Artificial intelligence's appetite for electricity is reshaping the semiconductor supply chain, and Infineon Technologies is staking its portfolio on that shift. The German chipmaker is dismantling the parts of its business that no longer fit and pouring the proceeds into power electronics built for the server farms of the next decade.
That realignment took concrete form on September 9, when Infineon disclosed an expanded collaboration with SolarEdge Technologies. The two companies are developing solid-state circuit breakers built on Infineon's silicon carbide JFET technology, electronic protection devices engineered specifically for the 800-volt direct-current distribution architectures that AI data centers require.
A Divestment That Pays for the Pivot
The money for this push is coming partly from the exit lane. Roughly a week before the SolarEdge announcement, Infineon agreed to sell its NOR Flash and F-RAM memory operations to Winbond for USD 1.12 billion, with the transaction expected to close in the second half of 2027. Management has been explicit that the low-margin memory unit no longer earns its place in the portfolio; the capital and management attention it absorbs are better spent on energy-efficient power semiconductors.
Infineon has also been buying capability rather than only shedding it. More than a month ago it acquired Indian specialist C2i Semiconductors, adding engineering depth to its power-management bench.
Should investors sell immediately? Or is it worth buying Infineon?
The product cadence reflects the same logic. On Tuesday the company unveiled the PSOC Control C3 Performance Line, microcontrollers aimed at real-time control in power and motor applications that meet the CNSA Suite 2.0 requirements for post-quantum cryptography. Earlier it brought the dual-channel 120-volt EiceDRIVER gate driver to market for power-supply designs in data centers. A webinar on battery-backup and capacitor-bank units for AI data centers is scheduled for next Tuesday.
The Numbers Behind the Ambition
Infineon's financial targets for the segment are aggressive. For fiscal 2026 the company is aiming for EUR 1.5 billion to EUR 1.6 billion in AI data center revenue, a figure it expects to climb to roughly EUR 2.5 billion in 2027.
The sell side is not of one mind on whether that trajectory holds. On September 8, Morgan Stanley downgraded the stock to Equalweight from Overweight and cut its price target to EUR 65, citing doubts about the pace of growth in the AI data center business and projecting segment revenue for 2027 and 2028 well below consensus estimates. Oddo BHF took the opposite view about a week ago, upgrading the shares to Outperform with an EUR 80 target and pointing to attractive valuation prospects following the earlier consolidation. UBS stayed on the sidelines, keeping a Neutral rating and an EUR 64 target on Monday.
Cyclical Drag Meets Structural Bet
The split verdict mirrors a company caught between two clocks. Automotive and industrial chips remain Infineon's traditional backbone, and when customer order intake in those markets weakens, even a technologically strong balance sheet feels the strain. On Thursday, media reports of worries about industrial conditions and automaker demand pushed the stock to the bottom of the DAX at one point. A modest rebound followed yesterday, lifting the close to EUR 57.22.
Despite the swings, the shares are up 52 percent since the start of the year, though they still trade at a 36 percent discount to their 52-week high — a valuation that captures investors' visible restraint.
Whether the uptrend survives now hinges on a single question: can AI infrastructure revenue actually hit the targets management has set in the coming quarters? Infineon is building its future at speed, but the present tempo is still dictated by the industrial cycle. For anyone holding the stock, that means patience — the payoff from rewiring data center power is a multi-year story, while demand from factory floors and car plants sets the tone today.
