Infineon Targets 99% Efficiency with €91M European Consortium as Shares Hit 52-Week High

Infineon stock hits €69.12 peak as it unveils Moore4Power, a €91M European project using chiplet tech to boost EV charging efficiency to 99% and cut railway inverter losses by 30%.

Infineon’s stock has more than doubled over the past twelve months, but the chipmaker isn’t resting on its laurels. As the share price touched €69.12 on Thursday — a fresh 52-week peak — the company unveiled a sweeping research initiative that aims to redefine power electronics for everything from electric vehicles to railway traction. The project, named Moore4Power, represents a strategic bet on heterogeneous integration rather than traditional transistor miniaturisation, and it arrives alongside a major internal restructuring that will take effect later this year.

The three-year programme, officially launched on 20 May 2026, brings together 62 partners from 15 European countries. ABB, Airbus and Alstom are among the industrial heavyweights that will collaborate on a total budget of €91 million, co-financed by national subsidies and the European Union’s Chips Joint Undertaking under the Horizon Europe framework. Infineon is acting as coordinator — a role that positions the DAX-listed group not merely as a manufacturer of power semiconductors but as the architect of an ecosystem spanning large corporations, SMEs and research institutes.

Technologically, Moore4Power breaks with the conventional “smaller equals faster” mindset. Instead of squeezing more transistors onto a die, the consortium will combine silicon, silicon carbide and gallium nitride with sensing, control and communication capabilities into tightly integrated systems. The key enabler is power-chiplet technology, which promises scalable architectures, flexible product variants and competitive costs. The applications targeted include renewable energy, e-mobility, rail transport and industrial power conversion.

The performance targets are eye-catching. In electric vehicles, the consortium aims for efficiency levels of up to 99% for bidirectional charging, slashing energy losses to near zero. For railway drives, the goal is to cut inverter losses by at least 30%. To accelerate development, the project will lean heavily on artificial intelligence, digital twins and automated processes. Infineon expects that the time from first fab samples to a validated datasheet will shrink from several weeks to just one. A digital product passport embedded directly in power modules will track operating conditions, health status and remaining useful life, enabling predictive maintenance and prolonging product longevity while reducing raw material consumption.

While Moore4Power is a long-term play with no immediate revenue targets, the timing of its launch is propitious. The shares have rallied 80.45% since the start of 2026 and stand 72.14% above their 200-day moving average — a sign that much optimism has already been priced in. Yet the operational backdrop has improved too. On 6 May, Infineon reported second-quarter revenue of €3.812 billion and a segment result of €653 million, translating into a margin of 17.1%. Management guided for third-quarter sales of roughly €4.1 billion and upgraded its full-year outlook, now calling for a “clearly higher” revenue figure, a segment margin around 20% and free cash flow of approximately €1.25 billion, up from a prior estimate of €1.0 billion.

Superimposed on the technology push is a corporate overhaul. From the fourth fiscal quarter of 2026, Infineon will rejig its structure into three new divisions: Automotive, Power Systems and Edge Systems. The move reflects a clear market shift: the automotive sector is softening, while demand for AI-related chips is booming. The restructure aims to channel resources more efficiently and convert the AI tailwind into operational profit.

Investors have already voted with their wallets. The stock’s 99.02% gain over twelve months leaves it trading near the top of its range. What remains to be seen is whether Infineon can translate the technological framework laid out in Moore4Power — system-level integration, chiplet architectures and digitised development processes — into marketable modules and faster customer approvals. If it can, the shares may have further to climb.
