Intel shares plummet more than 20% following weak guidance blamed on PC market slowdown
Intel's stock fell 22% after-hours due to weak Q4 guidance, despite beating Q3 earnings estimates. Revenue rose 21% to $16.51B, but PC market slowdown hurt client computing revenue, which dropped 5%. Data center and AI unit revenue surged 78%. Intel expects Q4 earnings of 25 cents per share and revenue between $15B and $16B, below analyst targets.

Market read
Intel's guidance cut and plant incident create immediate downside for the stock and signal broader concerns for the PC‑related semiconductor segment.
What to watch
The Ohio fab build‑out and potential SK Hynix partnership could provide long‑term capacity upside not reflected in the short‑term guidance.

Global chip makers may see heightened scrutiny on guidance and supply‑chain risks.
Counterpoint
If AI data‑center growth accelerates faster than expected, Intel's AI unit could lift earnings, mitigating the PC slowdown.
