Doncasters files for U.S. IPO after 26% revenue jump

Doncasters has filed for a U.S. initial public offering after first-quarter revenue jumped 26% to $237 million, a sharp gain that underscores how investors are rewarding aerospace and defense suppliers with visible demand. The long-established parts maker still posted a net loss of $47 million for the three months ended March 29, but that was narrower than the $53 million loss a year earlier as sales climbed from $188 million.

The filing comes as U.S. markets have warmed to companies tied to military supply chains, a shift driven by conflicts abroad, a larger U.S. defense budget and the view that some defense names are less exposed to AI disruption than other industrial businesses. Doncasters sits squarely in that trade. Its customers and end-market exposure stretch across aerospace engines and industrial gas turbines, with links to GE Aerospace, Honeywell, Pratt & Whitney, Rolls-Royce and Safran, plus program exposure tied to Boeing 737 and 787 aircraft.

That positioning gives the company a broader significance than a single balance sheet. Doncasters traces its roots to 1778, when Daniel Doncaster founded the business in Sheffield, UK. The company says it spent nearly 250 years building around metallurgical expertise, craftsmanship and reliability, evolving from file-making into steel converting, forging and now complex parts for high-performance superalloys used in engine and turbine applications.

The business has also been through a hard reset. In 2020, Doncasters underwent a debt restructuring after lenders took control from Dubai International Capital, and reporting at the time said the process wiped out about £900 million of debt. The turnaround later became associated with chief executive Mike Quinn and chairman Dirkson Charles, including the 2022 acquisition of Uni-Pol as part of a broader expansion.

Doncasters intends to list ordinary shares on the New York Stock Exchange under the ticker DPC. The company filed a Form S-1 with the U.S. Securities and Exchange Commission, and the number of shares and price range have not yet been determined. Jefferies and Morgan Stanley are lead joint bookrunners, with Barclays and Moelis as joint bookrunners and RBC Capital Markets and Rothschild & Co. as additional bookrunners.

For markets, the filing is another test of how far the defense and aerospace rally can carry industrial issuers. Doncasters’ revenue surge shows that demand is flowing through the supply chain, even if profits remain under pressure. If the IPO lands, it would give public investors a new way to bet on the manufacturing capacity behind the rearmament cycle.
