Sullivan Street Partners, a UK based mid-market buyout specialist, has completed its acquisition of the Aerostructures business of Senior plc and its rebrand to Zenix Aerospace.
The transaction was originally announced in July 2025 and represents Sullivan Street’s largest deal to date, with a total EV of up to £200 million.
The business will now trade under the Zenix Aerospace brand, a new, standalone group with a sole focus on aerostructures and aeroengines.
Zenix Aerospace comprises seven businesses previously owned by Senior plc, including AMT, Damar, Jet Products and Ketema in the United States, Weston in the UK, UPECA in Malaysia and the group’s Thailand operation.
Since signing the transaction in July, Sullivan Street has carved out the business and established Zenix Aerospace as an independent operator. A new head office has been established in Birmingham, UK, led by newly appointed Group CEO Scott McLarty, who spent the last two decades at Spirit AeroSystems. Zenix Aerospace’s sites will continue to be led by the same management teams from their current locations.
“As we launch Zenix Aerospace, I’m excited by what we can achieve together,” said Scott McLarty, Group CEO of Zenix Aerospace. “Our job is simple: be a partner our customers can rely on to deliver with precision, quality and consistency, and in doing so, build a modern, high-performing business with a clear ambition for the future.”
Zeina Bain, Managing Partner at Sullivan Street, commented: “We are thrilled to complete this acquisition and announce the launch of Zenix Aerospace, led by new Group CEO, Scott McLarty. This transaction represents a major milestone for Sullivan Street - Zenix is a high-quality, global business with a strong track record, deep customer relationships and a critical role in the aerospace supply chain. Since signing in July, we have worked closely with the team to deliver a complex, multi-jurisdictional carve-out and establish Zenix Aerospace as a standalone group, with a clear strategy focused on manufacturing excellence, supply chain reliability and growth.”
