TransDigm Group INC

Early history

TransDigm was formed in 1993 under the name TD Holding Corporation. It was founded with an initial equity investment of $10 million. The company was created by founders W. Nicholas Howley and Douglas Peacock, along with private equity firm Kelso & Company, in order to acquire and consolidate four industrial aerospace companies from IMO Industries Inc. in a leveraged buyout. Those four companies were Adel Fasteners, Aero Products Component Services, Controlex Corporation and Wiggins Connectors. Once the acquisitions were completed, TD Holding was renamed to TransDigm, Inc. and based in Richmond Heights, Ohio.

Originally, TransDigm manufactured and marketed a small group of aircraft components, such as batteries, pumps and fuel connectors. TransDigm expanded its range of aircraft component products over time through acquisitions of other aerospace component manufacturers, growing in revenues by about 25% per-year from 1993 to 1998. In 1998, Odyssey Investment Partners, a private equity firm, acquired TransDigm from Kelso & Company. After the September 11th attacks, the aerospace industry declined temporarily, resulting in losses and layoffs for TransDigm.

By 2002, TransDigm had grown to $300 million in annual revenues, up from $131 million in 1999. TransDigm was acquired from Odyssey Investment Partners by another private equity firm, Warburg Pincus, in 2003 for $1.1 billion. In 2006, the company went public on the New York Stock Exchange. By the following year, TransDigm had grown to $593 million in annual revenues.

Acquisitions

TransDigm focuses largely on acquiring other aerospace component manufacturers for expansion and growth. The company acquired more than 60 businesses in its first 25 years of operations, 49 of which were completed after TransDigm's initial public offering in 2006.

In 2010, TransDigm acquired competing aftermarket aerospace parts company McKechnie Aerospace Holdings for $1.27 billion. In 2016, it bought Data Device Corp., a power, networking and electronics company, for $1 billion. Two years later, TransDigm purchased a competing parts manufacturer, Esterline, for $4 billion. This was the largest acquisition in TransDigm's history.

In March 2022, TransDigm acquired the Montreal -based helicopter mission equipment company, DART Aerospace for approximately $360 million in cash. In May 2023, TransDigm acquired aviation and transportation research company Calspan for $725 million. In November 2023, TransDigm acquired Electron Device Business of Communications & Power Industries for $1.39 billion. In January 2026, TransDigm agreed to acquire Jet Parts Engineering and Victor Sierra Aviation Holdings from PE firm Vance Street Capital for $2.2 billion in cash.
