CLEVELAND, Dec. 31, 2025 /PRNewswire/ -- TransDigm Group Incorporated (NYSE: TDG) today announced it has entered into a definitive agreement to acquire Stellant Systems, Inc.

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."
