While Infineon's shares had recently suffered from concerns about the AI industry, today they were at times the strongest winner in the DAX with an increase of up to seven percent - as on Monday. In the early afternoon, the DAX stock gained 2.2 percent to 49.70 euros.
Today the semiconductor company took stock of its financial year, which runs until the end of September. The numbers are well received: With growth of twelve percent to 16.35 billion euros, Infineon posted record sales. The annual profit rose by almost half to 1.51 billion euros.
That was more than many market experts expected. "Infineon can exceed analysts' expectations and thus underlines its role as one of the potential beneficiaries of the global AI investment boom," said Andreas Lipkow, market analyst at brokerage firm CMC Markets.
One of the largest German AI profiteers
In fact, the AI boom in particular is boosting business. Infineon does not produce AI chips, but it does produce so-called power semiconductors, which are urgently needed for energy management in data centers. The data centers also require certain security chips from the German technology group.
“Infineon closed 2025/2026 with another record quarter and is starting the new financial year with continued strong momentum,” said CEO Jochen Hanebeck. "Our semiconductor solutions for powering data centers, for expanding and converting the energy infrastructure, for electromobility and software-defined vehicles make a particular contribution to this."
The group significantly increased the sales forecast for the business with power semiconductors for AI and traditional servers to almost four billion euros. Infineon had already announced in the summer that it wanted to significantly increase the previously assumed forecast of 2.5 billion euros.
This means that Infineon, together with Siemens Energy, remains the German economy's best hope of participating in the booming global expansion of AI infrastructure. “Infineon has a strong competitive position for the necessary power electronics,” said Wilfried Fritz, partner at the consulting firm BearingPoint. With a market value of almost 70 billion euros, the technology group from Neubiberg near Munich is one of the ten most valuable German companies.
Car business is increasingly recovering
But the core business with chips for the automotive industry is also doing significantly better again. Infineon benefited primarily from the increasing demand for electric cars as a result of high fuel prices.
The automotive business grew by eight percent in the past quarter and still accounts for almost half of group sales.
Don't worry about the end of the boom
Infineon boss Hanebeck does not share the current concerns about whether the AI boom will continue or whether it will suffer from increasing resistance to data centers or stricter regulation. Even if there is currently a backlash, the big tech companies will always find places where they can build their data centers - possibly even outside the USA. In addition, the expansion of AI data centers is also strong in other areas, for example in China, India or on the Arabian Peninsula.
Hanebeck also referred to a high long-term order backlog. "The demand from our customers is not only strong, but also long-term." Infineon can look forward to long-term delivery agreements with customers in connection with artificial intelligence worth around ten billion euros. Total sales are expected to increase by more than a fifth to 20 billion euros in the new 2026/27 financial year.
In the wake of the latest industry concerns, Infineon shares have lost up to 50 percent since their record high of almost 90 euros in June. Nevertheless, with an increase of 40 percent, the share is one of the strongest DAX stocks so far this year.
DAX back on record
Not least thanks to Infineon, the DAX is already on the hunt for records two trading days after its sharp collapse. With an increase of 1.2 percent to 26,586 points, it is already within sight of Thursday's record level of 26,692 points in the early afternoon.
