(Incorporated in Jersey)

We are a leading independent manufacturer of complex, highly engineered precision cast components and nickel- and cobalt-based superalloys serving the high-growth Aerospace and IGT end markets, both of which are experiencing demand super cycles. (Note: IGT stands for industrial gas turbine.)

Our products are manufactured to precise dimensional accuracy.

We believe we are one of a limited number of companies worldwide with the cutting-edge engineering, chemistry and metallurgy expertise, along with the large-scale specialized casting equipment required to manufacture these mission-critical parts under strict environmental controls for the most demanding applications within our end markets.

Our operations consist of three reportable segments: Engine Products — North America; Engine Products — Europe, and Turbo Wheels. We maintain 14 principal facilities.

Our product portfolio includes critical components of nearly every major commercial aircraft program, all categories of large and heavy-frame IGT platforms currently in production, including aftermarket content on legacy IGT platforms, and several defense and space programs, positioning us to capture a meaningful share of the multi-billion-dollar total addressable market across the Aerospace and IGT end markets. Many of the current and next-generation aeroengine and gas turbine platforms we serve are experiencing some of the highest build rates in the industry and our customers are actively working to further increase production on key platforms to meet exceptional demand. We work directly with the world’s leading Aerospace and IGT OEMs such as GE Aerospace, Honeywell, Pratt & Whitney, Rolls-Royce, Safran, Ansaldo Energia, Doosan, GE Vernova and Siemens Energy. The majority of our Aerospace and IGT engine products operate in extreme environments, characterized by high temperature and pressure, and as such are safety-critical, integral components of our customers’ supply chains.

We have nearly 250 years of history. Doncasters Group was established in Sheffield, UK in 1778 by Daniel Doncaster. We began as a file-making business and, over time, expanded into steel converting, forging, and is now focused on the manufacturing of investment castings and superalloys. In 1902, we were incorporated as a limited company and subsequently broadened our operations to include forging and drop forging trades. Over the following decades, we expanded our footprint through the acquisition of facilities in the United States, the United Kingdom and mainland Europe, and diversified into the Aerospace and IGT end markets. In 2001, we merged with Ross Catherall Group and were acquired by the private equity arm of the Royal Bank of Scotland. In 2006, we were acquired by Dubai International Capital who later exited as part of the 2020 restructuring described below.

On March 6, 2020, a financial restructuring of the Group was completed by way of a Scheme of Arrangement sanctioned by the English Courts that transferred ownership of the Group to DPC Holdings Limited.

Note: Net loss and revenue are in U.S. dollars for the 12 months that ended March 31, 2026.

(Note: Doncasters Group, also known as DPC Holdings, filed its S-1 on May 26, 2026, without disclosing the terms. Estimated proceeds were $100 million.)
