Intel Fab 28 Explosion Causes Two-Week Shutdown, $600M Loss, and Server Chip Delays

Fab 28 Explosion and Shutdown

An explosion occurred earlier this month at Intel's Fab 28 near Kiryat Gat, Israel. The incident led to the facility being shut down for two weeks. Intel's CFO, Dave Zinsner, stated during an earnings call that production was expected to restart by the end of the week following the shutdown.

Financial and Production Impact

Intel anticipates approximately $600 million in lost revenue over two quarters due to the explosion. This includes an estimated $300 million reduction in Q4 2026 revenue and a similar impact in Q1 2027. The company also expects a 2% reduction in its fourth-quarter non-GAAP gross margin. The explosion resulted in two fatalities and one serious injury.

Affected Products and Technologies

The disruption primarily affects server processors manufactured using Intel's 10nm-class process technologies, including Intel 7 (formerly 10nm Enhanced SuperFin). While Intel's latest Xeon 6 processors use Intel 3 for compute dies, their I/O dies are fabricated on Intel 7. Older generations like Xeon 5 Emerald Rapids and Xeon 4 Sapphire Rapids, also made on Intel 7, are still in demand and will be impacted.

Challenges in Mitigating Impact

Despite Intel having multiple 10nm-capable fabs globally, the company faces challenges in fully offsetting the production loss from Fab 28. This is due to strong existing demand for server processors and the complexities of transferring production, including product-specific manufacturing qualifications and the time and cost involved. Intel cannot repurpose product lines for newer I/O dies to produce older generation CPUs.
