Inside Infineon’s Record Run: A Hedge Fund Bet on GaN, a Boardroom Sale, and a €16 Billion Target

Infineon shares surge 77% YTD; Voxel Capital targets 58% upside by 2027 on GaN AI infrastructure. ITC bans Innoscience imports, cementing Infineon's patent advantage.

Kevin Salimian of Voxel Capital stood before investors at the Sohn Investment Conference in New York on 12 May with a simple message: Infineon is a misunderstood AI infrastructure play. His target — a 58% upside by the end of 2027 — rests squarely on the German chipmaker’s gallium nitride (GaN) technology, which he expects to power the next generation of data-centre power supplies, solar inverters and electric-vehicle drivetrains. By 2029, Salimian forecasts that AI-related revenue will account for a quarter of Infineon’s total sales.

One day before that pitch, Infineon supervisory board member Peter Gruber sold 10,001 shares at €61.76 apiece, pocketing roughly €618,000. The trade came just after the stock had touched what was then an all-time high. Market watchers typically view such insider sales as routine profit-taking rather than a red flag on the company’s prospects — and the shares have kept climbing since. They now change hands at €67.65, a new 52-week peak that extends the year-to-date gain to almost 77%.

The rally has strong operational foundations. In the quarter ended 31 March 2026, Infineon posted revenue of €3.81 billion, a 6% increase from the prior year. Net income came in at €301 million. The standout performer was the Power & Sensor Systems division, which surged 26% to €1.26 billion on margins above 20%, fuelled by insatiable demand from hyperscale data centres and AI accelerators. Management reaffirmed full-year guidance for revenue above €16 billion and free cash flow of €1.65 billion, with energy solutions for AI data centres alone expected to contribute roughly €1.5 billion.

Underpinning the commercial momentum is a legal victory that strengthens Infineon’s grip on GaN technology. The US International Trade Commission (ITC) has imposed an import and distribution ban on Chinese rival Innoscience, ruling that the company infringed a key Infineon patent. The order is subject to a 60-day review period by the White House. The dispute is global: last summer, the Munich I Regional Court also found Innoscience guilty of patent infringement in Germany. Infineon protects a portfolio of some 450 patent families and was the first manufacturer to mass-produce GaN chips on 300-millimetre wafers, giving it a structural cost advantage.

Further hearings in the German patent case are scheduled for June 2026, covering a second patent and a utility model. A clean sweep would cement Infineon’s position in the very segment that Voxel Capital is betting on.

Investors have already priced in much of this optimism. The stock is trading more than 70% above its 200-day moving average, and the relative strength index stands at 70.7 — firmly in overbought territory. The speed of the advance has triggered some profit-taking: in the session following the ITC announcement, shares slipped 3.44% to €65.32, though they quickly recovered to set fresh highs.

Infineon’s management is also reshaping the company to capitalise on the shifting landscape. From 1 July 2026, the four-division structure will be replaced by three units: Automotive, Power Systems, and Edge Systems. The new Power Systems division will bundle all business tied to AI data centres and network infrastructure, making the strategic pivot toward artificial intelligence and electrification explicit in the corporate hierarchy.

For Voxel Capital’s thesis to play out fully, Infineon will need to convert its GaN patent wins into sustained market share gains and keep the AI-driven revenue ramp on track. With a 25-year high already in the books and an activist pitch ringing in investors’ ears, the tension between fundamental promise and technical heat is sharper than ever.
