This article is based on an official press release from TransDigm Group Incorporated.
On January 16, 2026, TransDigm Group Incorporated (NYSE: TDG) announced that it has entered into a definitive agreement to acquisitions two aerospace aftermarket companies, Jet Parts Engineering and Victor Sierra Aviation Holdings, from private equity firm Vance Street Capital. The transaction is valued at approximately $2.2 billion in cash.
According to the company’s announcement, the strategy aligns with TransDigm’s long-standing strategy of consolidating proprietary aerospace component manufacturers with strong aftermarket revenue streams. The deal is expected to be funded through existing cash on hand, as of September 30, 2025, TransDigm reported holding approximately $2.8 billion in liquidity.
The acquisition includes two distinct entities that collectively generated approximately $280 million in revenue for the calendar year ending December 31, 2025. TransDigm stated that the purchase price includes certain tax benefits, though specific EBITDA multiples were not disclosed in the initial release.
The transaction is subject to customary closing conditions and regulatory approvals in the United States. Upon closing, both acquired companies will be integrated into TransDigm’s decentralized business model, where subsidiaries typically operate as independent units.
Both Jet Parts Engineering (JPE) and Victor Sierra Aviation Holdings (VSA) specialize in Parts Manufacturer Approval (PMA) components. These are FAA-approved alternatives to original equipment OEMs, a sector known for high margins and cost-efficiency for operators.
Headquartered in Seattle, Washington, JPE employs approximately 300 people. The company focuses on proprietary PMA parts and engineered repair solutions (DER repairs) for commercial, regional, and cargo airlines. Their portfolio includes replacement components for propulsion, pneumatic, and hydraulic systems.
Based in Baldwin City, Kansas, VSA employs roughly 400 staff and operates as a holding company for several general and business aviation brands. Key subsidiaries under the VSA umbrella include: This acquisition underscores TransDigm’s continued aggressive capital deployment in the post-2025 aerospace market. By targeting companies with nearly 100% aftermarket revenue, TransDigm is reinforcing its defensive moat, aftermarket parts are historically more recession-resilient than OEM Manufacturing.
The deal follows closely on the heels of TransDigm’s late 2025 agreement to acquire Stellant Systems for $960 million. The market reaction appears favorable, with TDG shares trading up approximately 1.7% following the news, suggesting investor confidence in the company’s ability to integrate these high-margin assets effectively.
