Infineon Jumps on Data Center Power Boom, but Cash Flow Disappoints

Germany's Infineon gave the AI trade something it badly needed on Tuesday: proof that data center spending is still showing up in the numbers. The chipmaker's shares jumped more than 6% after it forecast fiscal 2027 revenue of about €20 billion.

That's slightly ahead of the €19.81 billion analysts expected, according to Investing.com's coverage. It implies growth of more than 20% after a fiscal 2026 in which revenue rose 12% to €16.353 billion, per Infineon's own release.

The star of the outlook is power for data centers. Infineon expects that revenue to climb from €2.2 billion to close to €4 billion in fiscal 2027, covering both AI and traditional data centers.

The fourth quarter was solid. Revenue came in at €4.706 billion, in line with expectations, and the segment margin was 23.8% versus the 23.3% analysts expected. Adjusted gross margin of 45.1% also edged past the 44.9% forecast.

Not everything beat. Adjusted earnings per share were €0.60 against €0.64 expected, and the company's reported gross margin of 41.8% trailed the 43.2% forecast.

Management also pointed to pricing. Chief Operating Officer Ulrich Spiesshofer said Infineon raised power semiconductor prices twice in fiscal 2026, in April and July, and expects "a positive price environment" in 2027. For the first quarter, it guided to roughly €4.6 billion in revenue and a margin near 23%.

"The combined revenue volume of these agreements, both those already signed and those currently under negotiation, has now exceeded EUR 10 billion." — Jochen Hanebeck, CEO, Infineon

Hanebeck was talking about multi-year supply and capacity reservation deals, which he said underpin the data center demand. That matters because it suggests customers are locking in supply rather than just talking about it.

The reaction fits the wider tape. Last week's AI selloff was driven by fears that tougher data center rules could slow chip demand. Infineon's forecast, along with TSMC's October revenue of $17.88 billion, up 59.7% from a year earlier, as CNBC's market blog noted, argues the buildout hasn't stalled.

Citi analysts called the data center power forecast a "positive signal on underlying AI and data center demand despite recent concerns around deployment timelines," per CNBC.

Now the catch. Free cash flow is guided to about €1.8 billion versus the €2.26 billion analysts wanted, and adjusted free cash flow to about €2.2 billion versus €2.74 billion.

The reason is spending. Infineon plans €3 billion to €3.5 billion in investments, mainly in Dresden, Kulim and Villach, against €3.01 billion expected. It's also going to stop reporting its order backlog, which makes the demand story a little harder to track from the outside.

For investors, the question is whether that capacity spending pays off. Fabs built for a demand wave can become a drag if the wave arrives late. Infineon's long-term capacity reservation deals reduce that risk, but they don't remove it.

Auto demand is part of the picture too. Infineon expects mid-teens percentage growth in automotive and low-teens growth in edge systems, while power systems should grow significantly faster than the group as a whole.

The takeaway: Infineon is a cleaner read on AI power demand than most chip names, and it pays a dividend, with a proposed increase of €0.03 to €0.38 per share. If you own AI hardware, it's worth seeing as a diversifier into the power and infrastructure side.

Watch three things: whether free cash flow tracks toward €1.8 billion, whether data center power sales hit close to €4 billion, and whether price increases hold. U.S. investors will usually reach the stock through its over-the-counter ADR, so check liquidity before you trade.

Bottom line: strong demand, higher spending, thinner cash. Infineon's story is real, but the payoff is further down the road than the share price move suggests.
