Intel's Israel fab shutdown to cost $600 million and stall 10nm server chips

The physical story here is a factory floor that stopped moving. An explosion earlier this month at Intel’s Fab 28 in Kiryat Gat, Israel, killed two workers and seriously injured a third. ¹ The plant has been shut for about two weeks, and Intel says production should start back up by the end of this week. ²

Now the numbers. Intel finance chief David Zinsner put the damage at roughly $600 million in lost revenue spread over two quarters. ¹ The split is about $300 million in the fourth quarter and a similar amount in the first quarter of next year. ² The fourth quarter also takes a hit of roughly 200 basis points (two percentage points) on gross margin, which is the share of each sales dollar left after the cost of making the product. ²

The damage lands almost entirely on one product family. Zinsner said nearly all of the $300 million fourth-quarter impact is tied to 10-nanometer server products. ² CEO Lip-Bu Tan said the shutdown will hit fourth-quarter 10nm server shipments. ²

Why the wafers matter: a wafer is the round slab of silicon that gets cut into individual chips, and Intel is still sorting through every wafer that was mid-process when the plant stopped, to see which ones are usable. ² Zinsner expects most of the scrapped wafers to be written off in the fourth quarter, though he called the estimate early and promised updates. ² Intel’s 38% gross-margin guide would have been 40% without the Israel incident, an analyst noted, and Zinsner did not dispute it. ²

This is bad timing for a company already short on supply. Zinsner said demand for its data center and AI products continues to meaningfully exceed available supply, and he expects the industry to stay supply-constrained through 2027 and into 2028. ² Tan named three limits on server chip output: yields on the Intel 3 process, a shortage of advanced substrates (the base layer a chip package is built on), and the Israel shutdown. ² Zinsner added that, without the outage, the data center momentum seen this quarter would have carried into the fourth. ²

The broader quarter was rough for the stock. Intel shares fell sharply after hours on a weak fourth-quarter forecast, with revenue guided to $15 billion to $16 billion against $17.1 billion expected. ³⁴ Data center and AI revenue rose 78% to $7.3 billion in the third quarter, so the demand is clearly there. ³

Our read: The $600 million is a speed bump for Intel’s books, but a pothole for anyone waiting on 10nm Xeon parts. When demand already outruns supply, losing two weeks of output plus the scrapped wafers does not just delay chips, it pushes buyers to the back of the line. Watch the first-quarter update, because Zinsner himself said the estimate could still move.

On the bench: if you are specifying 10nm Xeon servers for the coming months, plan for longer lead times and ask your vendor for firm delivery dates rather than estimates. Everyone else shopping for server hardware should expect tight supply to be the norm well into 2027.
