Durham-based William Cook Holdings has agreed to sell an 80 percent stake in its tank tracks manufacturing division, Cook Defence Systems, to HEICO Corporation, a New York-listed company. The transaction is reportedly valued at over £100 million.

Cook Defence Systems specializes in producing tank tracks used in armored vehicles, serving both domestic and international defense markets. The sale marks a significant move for William Cook Holdings, as it seeks to realign its business focus.

HEICO Corporation, which is publicly traded on the New York Stock Exchange, is expanding its presence in the defense sector through this acquisition. The deal is expected to enhance HEICO’s capabilities in armored vehicle components and strengthen its position in the defense supply chain.

While specific terms of the agreement have not been publicly disclosed beyond the valuation and stake percentage, the transaction is subject to customary regulatory approvals. The companies have not indicated a precise timeline for completion.

Industry analysts note that this deal reflects broader trends in defense manufacturing, where strategic partnerships and acquisitions are common as firms adapt to evolving defense requirements and geopolitical dynamics.

Representatives from both William Cook Holdings and HEICO Corporation declined to comment further on the details of the transaction.
