Chairman of U.S. Aerospace Parts Company Liquidates Shares Worth Approximately $17 Billion

TransDigm Group Incorporated (TDG) non-executive Board Chair W. Nicholas Howley exercised stock options through a family trust and, later that same day, sold about $13 million worth of shares in the open market—yet he still holds an indirect stake valued at roughly $26 million.

In its fiscal 2026 second quarter, the company posted revenue of $2.54 billion and net income of $536 million, delivering double-digit growth and an EBITDA margin above 50%. Reflecting the acquisitions of Jet Parts Engineering and Victor Sierra, plus approximately $900 million in share repurchases, TransDigm raised the midpoints of its full-year revenue, EBITDA and adjusted EPS guidance.

On April 7, TransDigm completed its $2.2 billion acquisitions of Jet Parts Engineering and Victor Sierra. It is now awaiting the closing of a transaction to acquire defense electronics and satellite‐component maker Stellant Systems from Arlington Capital Partners for about $960 million.

Headquartered in Cleveland, Ohio, TransDigm Group is a high-value manufacturer of aerospace and defense components, supplying critical parts—such as actuators, pumps and valves, power systems and connectivity solutions—for commercial and military aircraft. W. Nicholas Howley co-founded the company in 1993, served as CEO until 2018, and now, as Board Chair, guides its long-term strategy and aggressive M&A agenda.
