Oldham Engineering, has entered an exciting new chapter with its acquisition by ASDAM, a leading sovereign defence and advanced manufacturing and sustainment group.

The acquisition marks a significant milestone in the company’s 160-year history. Founded in 1865 and operating from the historic Castle Iron Works site, Oldham Engineering has built a reputation for precision engineering, specialist fabrication, and large-scale manufacturing across industries including nuclear, defence, rail, power generation, steel, oil, construction and environmental services.

Under ASDAM’s ownership, Oldham Engineering will benefit from strengthened investment, enhanced international capability, and deeper alignment with global defence and advanced manufacturing programs. The move reinforces ASDAM’s strategic commitment to expanding its footprint in the UK and supporting critical sovereign industrial capability.

ASDAM’s CEO commented “Oldham Engineering has a long and proud history of delivering innovative engineering solutions. We are delighted to welcome the team into the ASDAM family and look forward to building on their legacy while accelerating future growth.”

Oldham Engineering’s leadership sees the acquisition as an opportunity to expand capacity, invest in advanced technologies, and unlock new opportunities across international markets. Existing customers will continue to receive the high-quality workmanship and service the company is renowned for, while benefiting from ASDAM’s broader expertise and resources.

The integration process is already underway, with both organisations working closely to ensure a smooth transition for employees, customers and partners. As Oldham Engineering looks to the future under ASDAM’s guidance, the company remains committed to the strong engineering traditions and skilled workforce that have defined it for more than a century.
