Infineon's Data-Center Power Play Runs Into a Split Analyst Verdict
Published on 09/12/2026 at 10:30 | Editorial boerse-global.de
Infineon has widened its cooperation with SolarEdge on semiconductor-based protection technology for 800-volt direct-current architectures, a tie-up that pushed the chipmaker's shares up roughly 4% during Friday's session before they closed at EUR 58.06. The two companies are targeting systems that operate at 800 volts DC — a design that is gaining traction in solar and storage applications as well as in selected industrial and automotive segments. Solid-state circuit breakers are meant to make such high-voltage systems safer and more efficient to run.
The SolarEdge deal is the latest in a string of power-electronics announcements from Infineon. In August the company struck a collaboration with LS Electric on DC power-supply solutions for data centers, and earlier this month it signed a memorandum of understanding with Skeleton Technologies aimed at highly efficient, resilient power-supply concepts for modern computing facilities. Together, the moves show Infineon methodically broadening its portfolio around the power needs of high-performance data centers — a field widely seen as one of the chip industry's most important growth engines given the AI infrastructure boom.
Beyond the data center
Infineon's ambitions stretch past server racks. The company is integrating its SECORA wallet technology into a new Hammer smartwatch built with mPTech, with a European market launch slated for November. Hardened HiRel power components from Infineon also flew aboard NASA's recently launched Nancy Grace Roman Space Telescope, underscoring how far the company's technology reaches beyond classic industrial and automotive applications.
Growth is coming through acquisitions as well. At the end of August, Infineon announced the takeover of Bangalore-based C2i Semiconductors, a move intended to sharpen its energy-management capabilities for AI data centers. Financial terms were not disclosed, and the transaction is expected to close in the third quarter of 2026.
Should investors sell immediately? Or is it worth buying Infineon?
Two banks, two directions
The expansion of the data-center business has landed against a divided analyst backdrop. On Tuesday, Morgan Stanley downgraded Infineon from "Overweight" to "Equal-Weight" and cut its price target to EUR 65, citing what it sees as limited near-term upside in the data-center business. The move followed an earlier target reduction from EUR 81 to EUR 65 in early September tied to risks in the AI data-center segment.
Warburg Research went the other way a day before Morgan Stanley's downgrade, lifting Infineon from "Hold" to "Buy" while keeping its EUR 84 target unchanged. Warburg pointed to the stock's now-lower valuation and to accelerating growth in chips for AI data centers — precisely the segment Morgan Stanley views with skepticism. The opposing calls lay bare a broader market uncertainty over how quickly and how forcefully Infineon will actually cash in on the AI infrastructure buildout.
A buyback with a narrow purpose
Separately, Infineon launched a limited share buyback program at the end of August. According to the company, it serves exclusively to meet obligations under existing employee participation programs and is therefore not a signal of broader capital returns to shareholders.
The stock has been largely unmoved by the recent flurry of headlines. Despite Friday's 4.5% jump, the shares sit 7.9% lower over the past 30 days — a hangover from quarterly figures published more than a month ago that have weighed on the stock since. The longer-term picture remains striking: Infineon is up 54% since the start of the year.
For investors, the current mix of operational progress in data-center power and diverging analyst opinions means the valuation of the AI growth story stays contested for now. Friday's reaction to the SolarEdge news shows the market is willing to reward tangible business wins — but a more durable stabilization may have to wait until expectations around the AI business come into clearer focus.
