From Auto-Lag to AI Star: STMicroelectronics Rewrites Its Script
15.06.2026 - 16:36:38 | boerse-global.de
STMicroelectronics has staged a stunning reversal of fortune. Just seven months after plumbing a low of €18.24, the stock stormed to a fresh 52-week high of €70.00 on Monday, closing at €69.21 for a daily gain of 3.42%. The year-to-date advance of nearly 196% marks a radical shift in identity: what was once a cyclical automotive supplier is now being priced as a structural beneficiary of the artificial?intelligence arms race.
The catalyst that rewired investor expectations arrived in February 2026, when STMicroelectronics unveiled an expanded partnership with Amazon Web Services. The multi?year, multi?product deal grants AWS options to acquire up to 24.8 million ST shares, exercisable only as certain payment milestones are met. Amazon’s financial stake is thus directly aligned with ST’s revenue growth from the data?center business. It is a far cry from the bleak landscape of 2025, when full?year revenue slid to $11.8 billion, the operating margin withered to 1.5%, and restructuring charges reached $376 million. Automakers, ST’s traditional bread?and?butter, disappointed across the board.
That cloud has lifted. In early June, management sharply raised its data?center revenue target. Instead of “well above $500 million,” the company now expects roughly $1 billion in 2026, and, should current demand dynamics and customer contracts hold, another doubling in 2027. The market responded with a near?30% surge over the past month, pricing in not a cyclical snap?back but a fundamental re?rating. The stock now trades 38% above its 50?day moving average and more than 125% above its 200?day line of €30.63. The 30?day annualised volatility of 77% underlines how far the name has travelled from its staid European chipmaker roots.
Should investors sell immediately? Or is it worth buying STMicroelectronics?
The numbers back the narrative. First?quarter 2026 net revenue came in at $3.10 billion, with a gross margin of 33.8%. Excluding the contribution from the NXP MEMS sensor acquisition, organic growth was 21.4%. For the second quarter, management guides revenue of $3.45 billion — a sequential increase of 11.6% and a year?on?year leap of 24.9%. Gross margin is expected to approach 35%. The NXP purchase itself bolsters ST’s longstanding strength in automotive and industrial sensors, creating a broader foundation even as the data?center story steals the spotlight.
Yet the speed of the rally has stretched valuation to extremes. The stock sits just a whisker below its all?time high, with a market capitalisation of €35.5 billion — a steep multiple for a company that earned only $166 million last year. The relative strength index of 67.3 is approaching overbought territory, leaving little room for disappointment. CEO Jean?Marc Chery points to normalising inventories and rising demand, but the next earnings report will be the real test. If the data?center segment fails to deliver the promised margins at scale, the premium that has been built on expectations could unwind as quickly as it was erected.
