Intel (NASDAQ: INTC) has announced a €5 billion (US$5.7 billion) investment at its Leixlip campus in Ireland to expand production capacity and research and development operations.

The programme will support output of Intel Xeon 6 and next-generation Xeon processors using the company’s Intel 3 process technology.

The expansion includes upgrades to existing fabrication facilities, new manufacturing equipment and improvements to the site’s automated track system, which links production modules across the campus.

Work on the capital expenditure programme began earlier this year and is expected to support construction, equipment installation and permanent technical roles. 

“This €5 billion investment represents a definitive commitment to maximize capacity at our Leixlip campus and increase what we can deliver to Intel Foundry customers,” said Naga Chandrasekaran, executive vice president, chief technology and operations officer and general manager of Intel Foundry.

He added that the investment would increase output of Xeon 6 and next-generation Xeon processors built on its Intel 3 process technology, while expanding advanced manufacturing capacity in Ireland.

The programme would also support Ireland’s semiconductor sector and the European Union’s efforts to strengthen domestic chip production.

Intel has invested more than €30 billion in Ireland since opening operations in 1989. Its Leixlip campus employs around 4,900 people. 

“Intel’s latest multi-billion-euro investment in Leixlip is a powerful vote of confidence in Ireland, our skills base and our position at the heart of Europe’s most advanced manufacturing ecosystem,” said Taoiseach Micheál Martin T.D. The expansion is expected to strengthen Ireland’s role in semiconductor supply chains and support its position as a technology and manufacturing hub.

Intel designs and manufactures semiconductors and computing technologies for data centres, personal computers, and other connected systems.

In the first quarter of 2026, Intel reported revenue of US$13.6 billion, up 7% year on year. Its loss per share was US$0.73, while adjusted earnings per share stood at US$0.29, according to its quarterly results. 

Intel Foundry also recently expanded its assembly and testing capacity in Penang, Malaysia, to meet growing demand for advanced semiconductor packaging.

IDA Ireland CEO Michael Lohan said the investment reflected Ireland’s skilled workforce and established semiconductor sector, while supporting advanced manufacturing and supply-chain capacity in Europe.
