CLEVELAND, Dec. 31, 2025 /PRNewswire/ -- TransDigm Group Incorporated (NYSE: TDG) today announced it has entered into a definitive agreement to acquire Stellant Systems, Inc. ("Stellant" or "the Company"), a portfolio company of Arlington Capital Partners, for approximately $960 million in cash, including certain tax benefits.

Stellant, headquartered in Torrance, California, is a leading global designer and manufacturer of high-power electronic components and subsystems serving the aerospace and defense end market. The Company's products are highly engineered, proprietary components with substantial aftermarket content and a strong presence across major aerospace and defense platforms. Approximately 50% of Stellant's revenue is derived from the aftermarket, and nearly all its revenue is generated from proprietary products. Stellant is expected to generate approximately $300 million in revenue for the calendar year ending December 31, 2025. The Company has manufacturing locations in Torrance, California; Williamsport, Pennsylvania; Melville, New York; and Topsfield, Massachusetts. The Company employs approximately 950 people.

Mike Lisman, TransDigm's Chief Executive Officer, stated, "We are excited to have an agreement to acquire Stellant. The Company's highly engineered, proprietary products generate significant aftermarket revenue and fit well with our long-standing business strategy. The Company has established positions across a diverse range of both commercial and defense platforms, adding new products and services to TransDigm's portfolio. As with all TransDigm acquisitions, we expect this acquisition to create equity value in-line with our long-term private equity-like return objectives."

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