Intel's third quarter looked fine at first glance: CNBC reports adjusted earnings per share of 52 cents versus 40 cents expected and revenue of $16.51 billion against $16.5 billion, with sales up 21% year over year. The shock came in the guide.

Intel projected fourth-quarter EPS of just 25 cents on $15–16 billion in revenue, while analysts polled by LSEG wanted 43 cents and $17.1 billion.

Shares fell more than 20% in extended trading Thursday, and Business Insider reports they opened Friday at $65.79, down from Thursday's $92.07 close — a 28% plunge that cut the stock's 2026 gain to roughly 67% from more than 130%.

What makes this crash unusual is the diagnosis.

CNBC notes PC shipments had already fallen 4% year over year, but CEO Lip-Bu Tan went further on the call, saying, per Business Insider, that the industry is navigating 'one of the most significant supply shortages in history' driven by demand for what he called super intelligence.

The AI buildout is absorbing memory and server chips, pushing memory prices up, making PCs costlier to build and buy, and prompting computer makers to order fewer Intel chips.

Finance chief David Zinsner said Intel does not expect a sustained recovery until memory availability improves and pricing normalizes.

The guidance also absorbed a one-off shock.

According to CNBC, Zinsner said an explosion at Intel's Israeli fab earlier in October, which killed two workers and seriously injured a third, will cost the company about $600 million in lost revenue over two quarters; Business Insider's version puts the fourth-quarter revenue hit at roughly $300 million from what Tan called an 'unfortunate and tragic accident' causing an extended shutdown of 10-nanometer shipments.

CNBC also reports client computing revenue of $8.1 billion fell 5% year over year and is expected to decline more than 20% in the fourth quarter, even as data center and AI revenue jumped 78% to $7.3 billion.

Even after the rout, management framed the damage as cyclical rather than structural.

CNBC quotes Tan saying Intel still sees robust long-term demand for CPUs as agentic applications like Meta's Muse and OpenAI's Dots orchestrate work on processors, and Zinsner pledged not to spend '$1 of capital' without clear evidence of customer demand.

CNBC also notes Intel has no major external foundry customers yet for 18A chips but expects 'a couple of customers ready to announce' within two quarters.

The market will not wait long for a read on whether this is Intel-specific: Business Insider reports AMD reports next week and Nvidia in mid-November, days after Google's record $500 billion single-day market cap loss.
