US continuous glucose monitoring developer Dexcom has officially opened its €300 million ($325 million) manufacturing and office facility in Athenry, Co. Galway, marking the company's first manufacturing site outside the United States and one of the largest single private-sector investments ever made in the West of Ireland. The plant has direct implications for Ireland's medtech manufacturing sector and its position as a global hub for advanced healthcare device production.

As reported by Construction Review, the facility was constructed over a 25-month period by John Paul Construction and completed in early 2026. The 40,000 sq m, four-storey complex sits on an 80-acre IDA Ireland strategic landbank and features 4,200 sq m of ISO-certified cleanrooms, laboratories and engineering spaces, alongside a newly commissioned wastewater treatment plant designed by the Coffey Group.

At full capacity, the Athenry site will produce up to 60 million CGM units annually, primarily the latest-generation Dexcom G7 wearable sensor, for distribution across European and international markets. The facility is expected to support more than 1,000 skilled graduate and technician-level jobs, in addition to the 500 construction roles generated during the build phase.

The project was recognised at the Engineering Excellence Awards 2026, winning Large Civil Project of the Year for its on-schedule delivery. The facility has been submitted for LEED Gold certification and incorporates rooftop solar photovoltaic panels, 100 electric vehicle charging spaces, a bike-sharing scheme and a dedicated shuttle bus service connecting to Athenry Train Station and Galway City.

Barry Regan, executive vice-president of worldwide operations for Dexcom, said: "Ireland has an exceptional talent pool and an established medtech sector. This makes Athenry the perfect location to establish a new, cutting-edge manufacturing facility."

The development forms part of a broader wave of advanced manufacturing investment into Ireland. Dexcom's Galway facility and Intel's separately announced €5 billion expansion at its Leixlip campus together reinforce Ireland's standing across two strategically critical sectors, medtech and semiconductors, and strengthen the country's role in European and global high-tech supply chains.

Over €1 million was paid to Galway County Council for regional public infrastructure as part of the project. The construction phase alone involved the excavation and complete on-site retention of 170,000 cubic metres of topsoil and subsoil, eliminating the need for off-site spoil transportation.
