Intel's €5 Billion Ireland Expansion: Leixlip, Fab 34, and the Strategy to Challenge TSMC

The expansion is expected to create several hundred permanent high-tech jobs, alongside engaging specialised tradespeople during construction .

Fab 34: The Heart of Europe's Most Advanced Chip Production

Fab 34, which officially opened in September 2023 at a total cost of €17 billion, is Intel's leading-edge high-volume manufacturing (HVM) facility designed for wafers using both Intel 4 and Intel 3 process technologies .

• Intel 4: Fab 34 began high-volume production of Intel 4 chips in September 2023, marking the first use of extreme ultraviolet (EUV) lithography for commercial chip production in Europe .
• Intel 3 (3nm-class): Intel 3 is the company's second EUV node, delivering an 18% performance-per-watt improvement over Intel 4. Intel shifted high-volume production of Intel 3 chips to Fab 34 in Ireland during 2025, making Ireland Europe's first 3nm-class production site .
• The Leixlip campus is one of only a handful of locations worldwide producing Intel's leading process technologies .

Fab 34 currently produces Intel Xeon 6 processors and next-generation Xeon chips built on the Intel 3 node, which are critical for powering AI data centers and high-performance computing workloads .

Apollo Buyback: Regaining Full Control for $14.2 Billion

In June 2024, Intel had sold a 49% equity interest in the Fab 34 joint venture to Apollo-managed funds for approximately $11 billion in a deal that allowed Intel to unlock and redeploy capital . On April 1, 2026, Intel announced a definitive agreement to buy back that 49% stake for $14.2 billion, regaining full ownership and operational control of Fab 34 .

• Intel financed the repurchase using a mix of available cash and approximately $6.5 billion in new debt offerings .
• The buyback is expected to positively impact the margins of Intel Foundry by internalising all production value from the facility .
• Apollo received a $3 billion premium over the original transaction value, reflecting Intel's improved financial position and the increased strategic value of the facility .

Employment Footprint in Ireland

Intel currently employs approximately 4,900 people across its Irish operations, centred on the Leixlip campus — which is Intel's largest manufacturing site outside the United States . The new €5 billion investment will add several hundred additional high-tech roles .

Strategic Context: Rebuilding Against TSMC Amid AI Demand

This expansion sits at the centre of Intel's broader turnaround strategy under CEO Pat Gelsinger's "five nodes in four years" plan, which aims to restore Intel's process-technology leadership and build a competitive external foundry business .

• AI-driven demand: Intel explicitly cites surging global demand for AI processors and high-performance computing as the primary driver for the Leixlip expansion . The chips produced at Fab 34 are Xeon server CPUs, described as an AI-adjacent play that supports AI infrastructure rather than directly competing with Nvidia's AI accelerators .
• Countering TSMC: Fab 34's ramp of Intel 3 (3nm-class) directly competes with TSMC's N3 family. By expanding leading-edge EUV capacity in Ireland, Intel gains a geopolitically strategic European manufacturing foothold that TSMC largely lacks, while adding volume to serve both internal products (future Xeon and AI accelerators) and external foundry customers .
• Full ownership regain: The Apollo buyback gives Intel complete strategic flexibility over Fab 34's output and margins — a key advantage as it tries to win major foundry clients who may be wary of third-party ownership structures .
