TransDigm Announces Acquisition of Jet Parts Engineering and Victor Sierra Aviation Holdings

CLEVELAND, Jan. 16, 2026 /PRNewswire/ -- TransDigm Group Incorporated (NYSE:TDG) today announced it has entered into a definitive agreement to acquire Jet Parts Engineering and Victor Sierra Aviation Holdings (collectively "the Companies"), portfolio companies of Vance Street Capital, for approximately $2.2 billion in cash, including certain tax benefits.

Jet Parts Engineering

Jet Parts Engineering ("JPE"), headquartered in Seattle, Washington, is a leading independent designer and manufacturer of aerospace aftermarket solutions, primarily proprietary OEM-alternative parts and repairs. JPE serves commercial, regional and cargo airline customers, as well as maintenance, repair and overhaul ("MRO") providers. JPE's products are highly engineered, proprietary PMA components with a strong presence across major commercial aerospace platforms. Nearly all of JPE's revenue is derived from the commercial aftermarket. In addition to its engineering headquarters in Seattle, Washington, JPE has engineering and component repair locations in Texas, New York, Florida, Alabama and the United Kingdom. JPE employs approximately 300 people.

Victor Sierra Aviation

Victor Sierra Aviation Holdings ("VSA") is a leading designer, manufacturer, and distributor of proprietary PMA and other aftermarket parts serving the commercial aerospace end market – primarily the general aviation and business aviation sectors. VSA is a leading collection of brands including McFarlane Aviation, Tempest Aero Group, and Aviation Products Systems. VSA offers a complete line of highly engineered PMA, custom design and OEM products, as well as service and repair stations. Nearly all of VSA's revenue is derived from the commercial aftermarket. VSA primarily operates out of three facilities: Baldwin City, Kansas; Burlington, North Carolina; and Granite City, Illinois. Additional satellite facilities are in Illinois, Texas, Kentucky and Washington to provide support and strategic proximity to customers. VSA employs approximately 400 people.

The Companies collectively generated approximately $280 million in revenue for the calendar year ended December 31, 2025. 

Mike Lisman, TransDigm's Chief Executive Officer, stated, "We are excited to have an agreement to acquire Jet Parts Engineering and Victor Sierra, two well run, profitable businesses that will fit well within TransDigm. The Companies' highly engineered, proprietary OEM-alternative parts and services generate nearly 100% commercial aftermarket revenue. These businesses offer a unique value proposition to their airline, business, and general aviation end user customers as an alternative to OEM parts and are each growing nicely. We will continue to offer this unique value proposition to customers and grow both companies under TransDigm ownership, where they will operate independently, consistent with our long-term approach to running our businesses. We look forward to working with and continuing to support the Companies' customers. As with all TransDigm acquisitions, we expect these acquisitions to create equity value in-line with our long-term private equity-like return objectives."

Nick Howley, TransDigm's Chairman added, "This is a natural progression for TransDigm. We have had a long-term and sizable PMA effort within our existing operating units. Since the formation of TransDigm, we have regularly used our uniquely broad aerospace engineering and market knowledge to design and offer our aftermarket customers a range of well engineered products that provide a mix of improved life, superior performance, and other benefits. Both Jet Parts Engineering and Victor Sierra are good businesses that align well with our model."

The acquisition is subject to regulatory approvals in the United States and customary closing conditions.
