TransDigm Group Incorporated (NYSE:TDG) on Friday said it signed a definitive agreement to buy Jet Parts Engineering and Victor Sierra Aviation Holdings from Vance Street Capital in a cash deal valued at about $2.2 billion, including certain tax benefits.
The two businesses focus on proprietary, FAA-approved aftermarket parts and repair solutions that offer airlines and aviation operators alternatives to OEM components.
Jet Parts Engineering (Seattle) designs OEM-alternative components and repairs largely for commercial airline and MRO customers, while Victor Sierra Aviation Holdings supplies proprietary parts and services mainly for business and general aviation through brands including McFarlane Aviation and Tempest Aero Group. Nearly all revenue at both companies comes from the commercial aftermarket.
Together, the companies generated about $280 million in 2025 revenue and employ roughly 700 people. JPE operates engineering and repair sites across the U.S. and the United Kingdom; Victor Sierra runs primary facilities in Kansas, North Carolina and Illinois with additional satellite locations.
CEO Mike Lisman said, “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.” Chairman Nick Howley called the move “a natural progression for TransDigm,” pointing to the company’s long-standing efforts in PMA and aftermarket engineering.
The acquisition follows a recent agreement to buy Stellant Systems for $960 million, reinforcing the company’s focus on specialized aerospace assets with recurring demand.
TransDigm held cash and cash equivalents of $2.808 billion as of September 30, 2025.
TDG Price Action: TransDigm Group shares were up 1.66% at $1457.34 at the time of publication on Friday, according to Benzinga Pro data.
