LHX vs TDG: audited financials
- Scale: LHX's $21.3B of revenue is about 2.4× TDG's $8.8B.
- Cash conversion: operating cash flow equalled LHX 1.93× net income; TDG 23.1% of revenue, or 0.98× net income. A ratio well above 1× usually reflects non-cash charges or working-capital release; well below 1× can reflect working-capital build or non-cash gains.
- Periods: the fiscal years end about 9 months apart (2025-01-03 for LHX, 2025-09-30 for TDG), so each figure reflects somewhat different demand and cost conditions.

What this comparison cannot tell you
This page does not contain licensed live prices, a valuation model, earnings estimates, portfolio constraints, or a forecast of future returns. SEC classifications can be broad, company descriptions can lag strategic change, and the latest annual filing may predate a material acquisition or divestiture. Read subsequent quarterly and current reports before making a decision.
A stronger business is not automatically the better stock. Starting valuation, expectations, capital structure, cyclicality, dilution, and the probability of each thesis determine the investment outcome. Use this comparison to frame the work, then verify the numbers in the linked filings and current company disclosures.
