Which STMicroelectronics listing does STM refer to?

What is behind the stock-price context?
A single-session move does not establish why the shares rose or fell, nor does it predict what they will do next. No verified explanation for the October 7 decline is available here, so it should not be attributed to a company announcement, earnings, semiconductor demand, or analyst action without evidence.
Rank #2
- Ultra-low-power with FPU ARM Cortex-M4 MCU 80 MHz with 1 Mbyte Flash, LCD, USB OTG, DFSDM

One useful context is the company’s latest reported quarter. STMicroelectronics said Q2 2026 revenue grew 26% year over year. Its investor-relations site describes the business as serving electronics applications, with strategy focused on Smart Mobility, Power & Energy, and Cloud-connected Autonomous Things: STMicroelectronics Investor Relations.
Q2 2026 reported results
For the quarter ended June 27, 2026, STMicroelectronics reported the following U.S. GAAP results in its July 23 release:

| Q2 2026 measure | Reported result |
|---|---|
| Net revenue | $3.49 billion |
| Gross margin | 34.8% |
| Operating income | $187 million |
| Net income | $222 million |
| Diluted earnings per share | $0.24 |
These figures are U.S. GAAP. The same release also gives a non-U.S. GAAP gross margin of 35.2%; it is a separate measure and should not be substituted for or combined with the 34.8% U.S. GAAP figure. See the Q2 2026 results release.
Management’s Q3 2026 outlook
In that release, the company’s midpoint outlook for Q3 2026 was revenue of $3.70 billion and gross margin of 37.0%. Those are management’s expectations, not reported Q3 results. STMicroelectronics President and CEO Jean-Marc Chery said in the July 23, 2026 release that demand had increased during the quarter, bookings were strong across end markets, visibility had improved, and distribution inventory was below the company’s standard target. That is management’s characterization of the quarter, not an independent measure of the broader market.
