Intel (NASDAQ: INTC) shares fell 3.6% during regular trading on Thursday, October 29, then dropped about 21% in after-hours trading following the company's third-quarter report, according to historical share-price data and Reuters' after-hours coverage. The extended-hours move followed a weaker near-term forecast, a production disruption at its Israel facility and continuing pressure in the PC market. After-hours prices can change before the next regular session.

Intel reported growth in the quarter

Third-quarter revenue was $16.5 billion, up 21% year over year. Intel reported non-GAAP earnings of $0.52 per share. Data-center and AI demand contributed to the quarter's growth, but the company's outlook shifted attention to supply constraints and its client-computing business, according to the company's earnings release.

Q4 guidance included a factory-related hit

Intel forecast fourth-quarter revenue of $15 billion to $16 billion and non-GAAP EPS of $0.25. The company said the shutdown at Fab 28 in Israel was expected to reduce revenue by roughly $300 million and gross margin by about 200 basis points, based on its early assessment. Intel also pointed to near-term headwinds across the PC industry in its quarterly results.

Reuters reported that the plant disruption could cost about $600 million in revenue over two quarters and that the company's outlook weighed on other chip shares in post-close trading. That is an estimate across a longer period; Intel's own release described the roughly $300 million impact included in its Q4 outlook.

The distinction between the regular-session decline and the larger after-hours move matters: the latter came after results were released and reflects trading in a thinner market. The next regular session will show how investors reassess the outlook with full-market liquidity.
