意法半导体二季度业绩后股价大跌，Q3指引未达到市场高预期

Google nearly doubles AI infrastructure spending as Q2 tops estimates
Investing.com -- STMicroelectronics NV stock dropped 14.9% to trade at €49.56 after the company published its Q2 2026 financial results before the opening of trading on European exchanges, triggering a sharp wave of profit-taking across Borsa Italiana.
The company reported second-quarter net revenues of $3.49 billion, a gross margin of 34.8%, operating income of $187 million, and net income of $222 million, or $0.24 diluted earnings per share, with non-GAAP net income reaching $291 million, or $0.31 diluted earnings per share. While the topline came in above the mid-point of ST’s own guidance range, the company’s Q3 2026 business outlook was set at a mid-point of $3.70 billion in net revenues and a gross margin of 37.0% — a figure that appears to have underwhelmed investors who had priced in a more aggressive recovery trajectory.
Shares of STMicroelectronics had surged more than 156% year-to-date heading into the print, and the stock was trading at a forward 12-month price-to-earnings multiple of 32.76x, well above the industry average of 22.42x — a stretched valuation that left little room for any guidance disappointment.
All major segments grew double-digit year-over-year except Power and Discrete, a soft spot that may have reinforced concerns about the breadth of the recovery. On the analyst front, several brokers including Susquehanna, TD Cowen, Morgan Stanley, and Jefferies had recently raised price targets or reiterated Buy ratings ahead of the print, setting a high bar for the results to clear.
Management highlighted continued strong demand in AI datacenters and raised its revenue ambition for that segment, now expecting datacenter revenues above $1 billion in 2026 and well above $2 billion in 2027, which management said confirms ST’s strong position in the evolving AI datacenter market. However, this positive narrative was not enough to offset the broader "sell the news" reaction. On the macro side, U.S. equity markets provided a weak backdrop, with the S&P 500 off 0.5% and the Nasdaq down 0.8%, adding incremental pressure on high-beta semiconductor names globally.
The combination of a lofty pre-earnings valuation, a Q3 guidance range that failed to exceed the market’s elevated bar, and a softening global equity environment converged to produce one of the steepest single-session declines for STMicroelectronics in recent memory. The stock’s day range of €48.50 to €50.68 — well below its previous session close of €58.25 — underscores the severity of the post-earnings reset, even as the company’s longer-term AI and datacenter growth narrative remains intact.
