Aerospace and defense contract liabilities are customer payments received in excess of revenue recognized on the associated performance obligations.

Lockheed Martin reported $11.4 billion of contract liabilities at December 31, 2025. During 2025, it recognized $6.3 billion of the contract liabilities that existed at the end of 2024 as revenue.

Why it matters

Contract liabilities show where customer funding or advance payments are ahead of accounting revenue recognition. They can provide useful context for cash flow and future revenue conversion.

Investor caution

Contract liabilities are not the same as backlog. They represent payments and revenue-recognition timing on existing performance obligations, while backlog follows a separate order and contract definition.

Source:

Use contract liabilities alongside contract assets and backlog to understand the timing between orders, work performed, billing, cash, and reported revenue.

Part of the Aerospace & Defense Program Economics

Connect backlog funding and conversion, contract and delivery mix, and long-cycle contract balances to understand aerospace and defense program economics.

How the model fits together
  • Backlog funding and conversion: Total backlog combines funded and unfunded firm orders under the issuer-specific backlog definition. Funded mix separates appropriated work from backlog still dependent on future funding, while 12-month and 24-month conversion estimates add expected revenue timing without turning backlog into guaranteed sales.
  • Contract and delivery mix: Fixed-price and cost-reimbursable sales mix show how contract risk is allocated, while product and services sales mix show what type of work is being delivered. These issuer-reported or analyst-derived mix views are not standardized peer profitability measures.
  • Contract-balance working capital: Contract assets represent recognized revenue that has not yet been billed, while contract liabilities reflect customer payments ahead of revenue recognition. They describe billing and cash timing on long-cycle work and are not backlog.
