Aerospace Parts Executives Cashing Out Hundreds of Billions Amid Strong Performance

TransDigm Group Inc. (NYSE: TDG) disclosed that on April 15, co-Chief Operating Officer Joel Ries exercised stock options and sold approximately $5.0 million (about KRW 6 billion) of shares on the open market. On April 20, the W. Nicholas Howley Family Trust also exercised lower-strike options, selling roughly $12.8 million (around KRW 17 billion) of stock while still maintaining an equity stake worth tens of millions of dollars.

Following these transactions, Ries’s direct holdings have declined to about $4.4 million (roughly KRW 6 billion) in value, and the Howley Family Trust’s indirect stake remains at approximately $26 million (around KRW 35 billion), ensuring that senior management continues to hold a meaningful ownership position.

In its fiscal 2026 second-quarter results, the company reported revenue of $2.544 billion (about KRW 3.4 trillion), net income of $536 million (approximately KRW 700 billion) and an EBITDA margin of around 52%. Reflecting the impact of the Jet Parts Engineering and Victor Sierra acquisitions and ongoing share repurchases, TransDigm raised its full-year guidance. (Source: PR Newswire)
