Key Takeaways
- STMicroelectronics boosted its 2026 data-center revenue forecast to approximately $1 billion from prior guidance of “nicely above $500 million”
- Management projects data-center revenue will double once more in 2027
- Shares of STM surged 11% Tuesday following the revised outlook
- The company maintains a commanding 90% market share in satellite chips for SpaceX, a partnership dating back to 2015
- While the stock has rocketed 168% year-to-date, one DCF analysis suggests it trades 38.6% above fair value
Shares of STMicroelectronics rallied 11% Tuesday after management significantly increased revenue projections for its data-center operations, pointing to robust demand fueled by artificial intelligence infrastructure investments.
The Geneva-headquartered semiconductor manufacturer now anticipates data-center revenue approaching $1 billion for 2026. This represents a substantial increase from previous forecasts calling for results “nicely above $500 million.” Looking ahead to 2027, management projects the segment will experience another year-over-year doubling—an enhancement from earlier projections of “well above $1 billion.”
At the time of recent valuation work, STM was changing hands near €62.82, reflecting a remarkable 168% climb year-to-date as of early June 2026.
The automotive semiconductor market, traditionally a core strength for STMicroelectronics, has experienced weakness stretching beyond twelve months. In response, the firm has strategically shifted focus toward power management semiconductors and optical connectivity products deployed in data centers—both critical components in the expanding AI hardware ecosystem.
SpaceX Partnership Provides Additional Upside Catalyst
STMicroelectronics has supplied semiconductor solutions for SpaceX satellite systems since 2015 and commands an estimated 90% share of this specialized market. With widespread speculation regarding SpaceX’s anticipated public offering this month, investor interest in this partnership has intensified.
The semiconductor maker is also exploring preliminary concepts around orbital computing facilities—data center infrastructure positioned in space. Remi El-Ouazzane, leading the relevant business unit at STMicroelectronics, characterized it as “something that we are very much involved with but have not been able to scope properly yet.”
While potentially significant long-term, this opportunity remains in early conceptual stages with no financial projections disclosed.
The broader analog semiconductor sector participated in Tuesday’s upward movement. ON Semiconductor advanced 5.6%, Texas Instruments climbed 2.5%, and Infineon Technologies appreciated 5.9% during U.S. market hours.
Valuation Concerns Emerge Following Massive Rally
Following the substantial price appreciation, several market observers are evaluating whether the valuation has outpaced underlying business fundamentals.
Simply Wall St’s discounted cash flow analysis establishes STMicro’s intrinsic value at €45.32 per share—indicating the current price of €62.82 may represent a 38.6% premium to that calculation.
The research firm assigns STMicro a valuation score of merely 2 out of 6, placing it within overvalued territory according to their methodology.
Price-to-sales metrics present a more nuanced perspective. STM carries a P/S multiple of 5.20x, positioned above the semiconductor sector median of 4.88x yet below the comparable company average of 6.34x. Simply Wall St’s proprietary “Fair Ratio” metric registers at 11.87x—which would actually suggest undervaluation under that specific framework.
Trailing twelve-month free cash flow remains in negative territory at approximately -$702 million, though forecasts anticipate a reversal to roughly $967 million during 2026, expanding further to $3.47 billion by 2030.
Recent price action shows a 6.6% advance over the trailing seven days and 28.1% appreciation across the past thirty days, demonstrating continued momentum as summer approaches.
