Aerospace supply chain specialist FDH Aero has agreed to sell a majority in the business to Bain Capital Private Equity.

The deal was announced today and is expected to drive the next phase of growth at the California headquartered global firm.

Audax Private Equity, FDH’s majority shareholder since 2017, will remain a significant investor in the company, according to the announcement.

FDH said the investment from Bain will be used to increase “capabilities, service model, and global reach, through both organic initiatives and strategic acquisitions”.

Current chief executive Ian Walsh will continue to head up the company alongside the existing management team.

Walsh said: “This partnership marks an important and planned milestone in our growth plans and reflects the strength of our people, our business, and the opportunities ahead to create value for our customers and stakeholders.

“With Bain Capital’s deep operational and strategic experience, together with the continued support of Audax, we are well positioned to continue investing for future growth.

“Together, we remain focused on putting customers first and strengthening our position as a trusted global supply chain solutions partner.”

FDH Aero specialises in hardware, electrical products, and consumables and expendables for OEM and aftermarket customers in defence and commercial aviation.

The firm supports customers through a global platform with more than 1,500 employees across 15 countries.

Since Audax Private Equity’s initial investment in 2017, FDH has expanded operations across five continents, completed 12 acquisitions that broadened its product offering and extended its commercial reach, and grown revenue significantly.

Audax Private Equity partner David Wong said: “Since our initial investment nine years ago, FDH Aero has established itself as an integral supply chain partner to the global aerospace sector,.

“We are proud of FDH’s leadership team and 1,500 employees worldwide for their stewardship and look forward to working with Bain Capital through this next chapter of FDH’s growth.”

Stephen Thomas, a partner at Bain Capital, added: “FDH has built an exceptional platform in aerospace and defence logistics, distinguished by deep customer relationships, a service-first culture, and a level of execution that gives us tremendous confidence in the business.

The transaction remains subject to customary regulatory approvals and is expected to close in the second half of 2026.

“We are excited to partner with Ian and the full FDH team,” said Ajay Kumar, a Partner at Bain Capital. “Together, we plan to continue investing in the company’s capabilities and inventory availability to further strengthen its customer-centric growth strategy.”
