Infineon ties its €3-3.5 billion chip buildout to customer commitments, and Vertiv signed first
Europe's largest chipmaker booked a record €16.35 billion year and guided fiscal 2027 to €20 billion, yet will not spend €3-3.5 billion on capacity until buyers commit. Its near-€4 billion data-center bet hangs on signatures, and this week Vertiv gave the first one.

Munich heard an unusual sentence from a chip boss this week. At an industry gathering on November 9, Infineon+0.87% — Infineon, up 0.87 percent today CEO Jochen Hanebeck said customers must commit before his company expands capacity further: "There are limits to what we can shoulder" 1. The €3 billion to €3.5 billion investment plan for fiscal 2027 depends, the company said, on expected customer demand 1.
The €20 billion year is booked, the fabs are not
The reluctance sits oddly beside the numbers reported the next morning. Fiscal 2026, which closed September 30, brought record revenue of €16.35 billion, up 12%, with a segment-result margin of 19.7% 2. After-tax profit jumped 49% to €1.51 billion 3.
For fiscal 2027 Infineon guides revenue up more than a fifth to about €20 billion, profitability into the mid-20s, and data-center revenue near €4 billion, up from €2.2 billion (€1.7 billion of it AI-specific) 2 3. That €4 billion data-center target 2 is the hinge: it must nearly double in one year, and Hanebeck will not pour concrete on hope. The American-listed shares rose about 9% on the day 6.

Two signatures, neither of them an order
The first answers arrived the same week. Vertiv−1.73% — Vertiv, down 1.73 percent today, the data-center power and cooling specialist whose 800-volt DC systems sit in the AI rack power chain, signed a three-year strategic agreement for silicon and silicon-carbide power semiconductors to secure supply for those systems 4.
In Seoul, power-supply maker SOLUM signed a memorandum of understanding covering intermediate bus converters, battery backup units and power supplies, showcasing a 26 kW battery-backup converter for 800-volt racks with mass production targeted for 2027 7. The next leg is already funded: a €1.1 billion gallium-nitride build at Villach, backed by €319 million in European Commission-approved aid 1. Infineon expects data centers to draw 7-8% of world electricity by 2030, up from about 3% today 5.
What the MoUs are not
Fair warning for bulls: neither signature is a purchase order. The SOLUM deal supplies reference designs and technical support, not volumes 7. And AI data-center chips were only €1.7 billion of last year's €16.35 billion; cars, grids and software-defined vehicles carry most of the €20 billion guide, which analysts called roughly in line with expectations 2 3.
February 3 is when memoranda either become contracts or don't
Infineon reports again on February 3, 2027 1. Watch whether hyperscalers convert memoranda into binding capacity commitments, as Vertiv did this week. A binding commitment is the only document that survives a downturn; a memorandum is marketing until then. Most suppliers in this boom build first and find buyers later; Europe's largest chipmaker is refusing to.
