Sources: All figures are company-disclosed, sourced from TransDigm Group's FY2025 Form 10-K (filed 11/12/2025, SEC EDGAR, CIK 0001260221, accession 0001260221-25-000081, Note 15 'Segments' tables R90/R8 and Item 1 Business) and the FY2025 Q4/full-year earnings release (PRNewswire/Morningstar, 11/12/2025). Total net sales FY2025 = $8,831M (FY2024 $7,940M, FY2023 $6,585M, FY2022 $5,429M, FY2021 $4,798M per respective year-end press releases). Segment net sales (Power & Control $4,559M, Airframe $4,112M, Non-aviation $160M) sum exactly to total net sales ($8,831M), so the revenue pie has no gap. The segment pie labeled 'EBITDA' uses the 10-K's disclosed segment EBITDA (Power & Control $2,595M, Airframe $2,210M, Non-aviation $67M; sums to total segment EBITDA of $4,872M before corporate/other reconciling items to consolidated EBITDA As Defined of $4,760M) as the closest company-disclosed proxy for segment operating profitability; TransDigm does not separately disclose segment operating income (EBIT). No segment showed an operating loss. TransDigm's 10-K describes long-run approximate ranges of net sales by end market (commercial/regional aftermarket ~30-35%, commercial aerospace OEM ~25-30%, defense ~35-40% of annual net sales) rather than an exact FY2025 percentage breakdown, so this was NOT built as a pie (ranges don't sum cleanly to 100%) and is instead shown as a KPI-table row in the company's own words. Net income, EBITDA margin, employee count (~16,500 as of 9/30/2025), aftermarket mix (~55% of FY2025 net sales), and proprietary-products mix (~90% of FY2025 net sales) are all company-disclosed. Free cash flow ($1,816M) is calculated from 10-K cash-flow-statement figures (operating cash flow $2,038M minus capex $222M) and is not a GAAP or company non-GAAP line item. No credible, specifically-attributed third-party market-share estimate for TransDigm's niche component markets was found during this research, so none is included (per instructions, omitted rather than guessed).
