Infineon Sheds Legacy Memory Line Just as AI Doubts Test Its Premium Rating

Infineon falls 3.6% to EUR 58.21 after Morgan Stanley cut its rating to Equalweight, trimming its price target to EUR 65.00 from EUR 81.00.

Infineon's decision to offload its memory-chip operations has landed against a far less forgiving market backdrop than the company might have hoped for. The stock gave up 3.6% on Wednesday, closing at EUR 58.21, as jitters across the semiconductor space overshadowed what management frames as a deliberate sharpening of its portfolio.

For a DAX-listed group that has already climbed 54% since the start of the year, the timing is awkward. Investors are no longer rewarding pure technology enthusiasm; they want proof that the ambitious growth story attached to artificial intelligence can justify the multiple. The pullback came just days after Morgan Stanley cut its rating to "Equalweight" from "Overweight" on 8 September, trimming its price target to EUR 65.00 from EUR 81.00.

Two Narratives Pulling in Opposite Directions

The Munich-based chipmaker is simultaneously being rewarded and punished for the same strategic pivot. By exiting memory components — a business inherited through earlier acquisitions — and sourcing those parts from outside suppliers instead, Infineon frees capital for the segments where margins are fatter. Finance chief Sven Schneider described AI chips for data centers in early August as the largest growth engine in the company's history.

That repositioning carries a visible cost. Roughly EUR 350 million in annual revenue and 350 employees will transfer as part of the sale to Winbond, expected to close in the second half of 2027. The market's muted response suggests investors are fixating on that near-term shortfall rather than the strategic upside.

Yet the underlying order book tells a different story. At the end of June, Infineon's backlog stood at EUR 30 billion — an increase of EUR 5 billion in just three months. The third quarter of fiscal 2026, reported on 5 August, delivered revenue of EUR 4.17 billion, more than 12% above the prior-year figure.

The Data Center Question Mark

What ultimately determines whether Infineon keeps its valuation premium is the pace at which its power-supply solutions for AI data centers scale. The legacy automotive and industrial power electronics businesses generate dependable returns, but the AI narrative drives the multiple. Morgan Stanley forecasts EUR 2.8 billion in data center revenue for fiscal 2027 and does not expect Infineon to raise its own EUR 4.0 billion guidance.

The investment bank's projections for the Power & Sensor Systems segment sit 18% below consensus for fiscal 2027 and 24% below for fiscal 2028. Unless the board can counter that skepticism with hard order data, the premium Infineon commands over conventional chipmakers risks eroding further.

A Broader Base Than Pure AI Players

Optimists point to the company's diversified footing. In the third quarter of fiscal 2026, Infineon posted record revenue of EUR 4.172 billion, with segment profit of EUR 797 million and a margin of 19.1%. That operating cushion confirms demand for automotive and industrial semiconductors remains intact, even as the AI debate swirls.

Capacity expansion continues on schedule. In Dresden, the ESMC joint venture — 70% controlled by TSMC, with Infineon, Bosch and NXP each holding 10% — celebrated the topping-out of its EUR 10 billion fab on 14 September. Production is slated to begin in 2027 at the EUR 5 billion-funded site, which is expected to create around 2,000 jobs and secure long-term automotive chip supply.

Where the Risk Really Sits

The flip side is the genuine danger of a re-rating if consensus expectations miss. Should growth in Power & Sensor Systems undershoot analyst forecasts, earnings revisions could bite hard. With Morgan Stanley's estimates for that segment well below the average, any operational slowdown carries the potential for further downgrades.

A second vulnerability lies in a possible spending pause among large server-farm operators. If calls to slow model development translate into budget cuts at cloud providers, Infineon would realize its hoped-for demand surge in power-supply chips later than anticipated. In that scenario, margin targets would need resetting, while heavy upfront investment in capacity expansion would weigh on returns in the interim.

Chart Levels to Watch

Two paths are emerging for the share price. As long as the stock defends the EUR 55 area, the longer-term uptrend remains technically intact. A sustained break above the 50-day moving average of EUR 59.23 would signal that the market views the sector-wide caution as temporary noise. Should sentiment deteriorate further and the shares fall below that support, the focus shifts to a deeper correction.

The company gets its next chance to back up the operational story with fresh figures when fourth-quarter numbers are expected on 10 November.
