Infineon: The €1.5 Billion AI Power Bet That Could Outlast the Broadcom Shock

Infineon's 13% rout follows Broadcom's weak earnings, but its AI data center power management story drives long-term optimism, with raised guidance and conservative analyst forecasts.

The European chipmaker’s stock took a near-13% tumble on Friday, wiping out weeks of relentless gains and dragging the shares to €74.51. But beneath the surface of that single-day rout lies a fundamental shift in how the market is valuing the company — one that has little to do with the usual cyclical swings of the semiconductor industry.

The sell-off was triggered by a lacklustre earnings report from US heavyweight Broadcom, which cast a shadow over the entire sector. The Nasdaq slipped as a result, and high-flying technology names across the board gave back ground. Market participants described the pullback as a healthy cooling-off after a rally fuelled by artificial intelligence euphoria had pushed Infineon up more than 94% since the start of the year.

Yet the long-term investment case for Infineon is increasingly tied to a different part of the AI story: power management. As data centres for artificial intelligence consume ever more electricity, the company’s portfolio of power semiconductors, silicon carbide components and automotive chips positions it as a key supplier of energy infrastructure — not just compute hardware.

Infineon has already started to show hard numbers behind that thesis. On 6 May the group reported second-quarter revenue of €3.812 billion and a segment result of €653 million, with a margin of 17.1%. Management raised its full-year guidance, saying revenue would now rise “clearly” rather than “moderately”. More importantly, revenue from power supply for AI data centres topped €700 million in fiscal 2025, and the company is targeting around €1.5 billion for fiscal 2026.

Analysts are taking note. Jefferies considers both Infineon’s own forecasts and market expectations to be conservative, leaving room for positive surprises after an already strong run. Goldman Sachs, after meetings with management, highlighted that the production base is well aligned with rising AI demand. Bank of America sees Infineon gaining market share in silicon carbide for data centres, estimating a 37% slice by 2027 to 2028, compared with roughly 15% for STMicroelectronics.

That narrative is re-shaping the investment debate. Infineon is no longer viewed solely as an automotive-chip play vulnerable to inventory cycles. It now commands a premium for its exposure to the infrastructure backing the AI boom.

Macroeconomic headwinds, however, temper the optimism. The closure of the Strait of Hormuz has driven up energy costs, raising margin risks for an energy-intensive manufacturer. At the same time, expectations of imminent interest rate cuts have faded. The US labour market added more than 170,000 jobs in May, reinforcing inflation fears and putting pressure on richly valued tech stocks whose future earnings must be discounted more heavily.

Technically, the shares remain in a robust position despite the bruising session. At €74.51, the price sits well above its 200-day moving average of €42.66 and is 28.4% above the 50-day line of €58.03. The relative strength index, at 55.1, has retreated from overbought territory into neutral ground, suggesting the excess froth has been cleared. The 30-day annualised volatility of 73.12% underscores how sensitive the stock remains to sector headlines.

The next major test will come with the quarterly earnings report. Investors will be watching closely to see whether Infineon can back up the bullish AI power-supply story with hard revenue and margin data, particularly in the areas of silicon carbide, automotive chips and data-centre power solutions. Until then, the €1.5 billion revenue milestone remains the beacon that could help the stock weather further turbulence.
