Transdigm Group Incorporated
A designer and supplier of proprietary aerospace components used in aircraft around the world. Its parts span three segments — Power & Control (engines and power systems), Airframe (cabin and non-power structures), and Non-aviation (ground transport, space, and energy). The company has grown by acquiring dozens of specialized aerospace parts businesses since 1993, and much of its revenue comes from replacement parts and repairs for aircraft already in service.

Select a row to see that insider’s individual transactions. Sum of the holdings confirmed in the 12 months before this insider's last filing. A Form 4 reports a holding per line — held directly, or through a named trust, partnership or foundation, and in each share class separately — never a person’s total. Lines not restated in that time are left out and shown apart: an active filer restates what they still hold, so a line they did not restate is more often an entity since renamed, whose shares a successor line reports too. An amber marker means some were left out.
Net open-market activity over all recorded history: -69.77M shares. Grants, option exercises and tax withholding are excluded — they are compensation mechanics, not decisions to buy or sell.
