STMicroelectronics N.V. (ISIN NL0000226223) stock closed at EUR 44.63 on Euronext Paris on September 9, 2026, down 0.84% on the day and extending a modest pullback from recent highs. As of September 9, 2026, the company is targeting more than USD 2,000,000,000 in artificial intelligence data center revenue for 2027, with its finance chief providing a detailed breakdown of this outlook at Citi's 2026 Global TMT Conference.

AI data center ambitions drive long-term story

According to Reuters on September 9, 2026, STMicroelectronics' chief financial officer Lorenzo Grandi told Citi's Global TMT Conference that about 80 percent of the more than USD 2,000,000,000 AI data center revenue targeted for 2027 should come from chips used in fiber optic data links, with the remaining 20 percent tied to cooling systems and power conversion inside servers. This split underscores that the near term is expected to be driven mainly by connectivity, while server power is seen as a larger opportunity after 2028, when STMicroelectronics does not expect meaningful revenue from that segment before then.

As Investing.com reported on September 9, 2026, management said that demand across major end markets such as AI infrastructure, automotive, industrial and satellite remains stronger than supply, with book-to-bill ratios well above 1.0 and some industrial product lead times stretching to about 50 weeks. STMicroelectronics indicated that it raised its data center revenue outlook to above USD 1,000,000,000 in 2026 and well over USD 2,000,000,000 in 2027, showing a step up versus earlier expectations and highlighting the scale of the AI infrastructure opportunity.

In the same conference comments, gross margin for the third quarter was described as about 37 percent, including around 70 basis points of unloading charges and 50 basis points of costs linked to a manufacturing reshaping program, according to Investing.com. Management expects more than 400 basis points of gross margin improvement over time from this manufacturing reshaping plan, which would lift the margin from roughly the high 30 percent range toward the mid 40 percent level, assuming execution risks around fab closures and customer qualifications are successfully managed.

Analysts focus on margins and multi-year growth

Italian financial daily Il Sole 24 Ore highlighted on September 10, 2026 that the messages from STMicroelectronics' chairman and CFO at Citi's Global TMT Conference were broadly in line with guidance given at the end of July, confirming revenue estimates of around USD 1,000,000,000 for AI data centers in 2026 and over USD 2,000,000,000 by 2027. According to the article, management reiterated that it is aiming for gross margins in roughly the mid 40 percent range over time, supported by an improved product mix, a disciplined pricing policy and optimization of production capacity, indicating a clear margin recovery narrative versus the current 37 percent level discussed for the third quarter.

Equita analysts commented in the same Il Sole 24 Ore piece that they remain positive on STMicroelectronics, confirming a Buy rating and a target price of EUR 68. Intermonte took a more cautious stance, keeping a Neutral rating but with a target price of EUR 54.50, suggesting that while both houses see structural growth drivers into 2027, they differ in how much of this is already reflected in the share price. The spread between the two targets, from EUR 54.50 to EUR 68, offers investors a quantified view of the upside that different analysts see versus the current mid 40 euro trading range.

Separately, Citi reiterated its Buy rating on STMicroelectronics, valuing the group on a price to earnings multiple of about 18 times estimated earnings for the 2028 fiscal year, which translates to a price target of EUR 65, according to an article from Milano Finanza dated September 10, 2026. The same report noted that the stock traded around EUR 44.95 in Milan on September 10, 2026, implying that Citi's target of EUR 65 points to potential upside of roughly 44 percent from that level if its medium term assumptions materialize.

MarketScreener's Italian edition reported on September 10, 2026 that Berenberg reiterated its Buy rating on STMicroelectronics and continues to see multiple drivers supporting growth, while AlphaValue and Baader Europe maintained a positive stance earlier in the week, according to Zonebourse. These views underline a consensus that STMicroelectronics is well positioned in structural themes such as AI infrastructure, automotive electronics and industrial automation, even as analysts continue to monitor cyclical segments and execution on the manufacturing reshaping program.

Recent share performance and valuation signals

STMicroelectronics shares have seen notable gains over the past year, with a discounted cash flow analysis on September 10, 2026 indicating that the stock delivered a year to date increase of 99.5 percent and a one year gain of 100.8 percent, according to GuruFocus. The same analysis suggested an intrinsic value of about USD 39 per share based on its discounted cash flow model, implying that after the strong price run, the market valuation may be ahead of the DCF based estimate, a factor that some investors may weigh against the bullish revenue and margin outlook.

A separate overview from XTB on September 9, 2026 noted that STMicroelectronics shares closed at EUR 44.63 on Euronext Paris that day, a decline of 0.84 percent in the session, as the stock consolidated after earlier gains. The same article reiterated that the company is confirming its aim of exceeding USD 2,000,000,000 in AI data center revenue by 2027, mainly driven by optical connectivity, aligning with the detailed breakdown presented by the CFO at Citi's event and providing a tangible revenue figure for investors tracking the AI theme.

Stock portal data from Euronext Paris indicated the closing level of EUR 44.63 for STMicroelectronics shares on September 9, 2026, with a daily performance of minus 0.84 percent and a five day change of about 2.07 percent, according to information summarized in a MarketScreener factors to watch overview on September 10, 2026. In this context, the recent pullback still leaves the shares close to their 52 week high zone, while analysts' target prices in the mid 50 to high 60 euro range suggest further upside if the company delivers on its strong bookings, margin recovery and AI revenue trajectory.
