    Boeing Navigates 10x Debt-to-Equity and Negative Cash Flow on $89.5B Revenue

    Question

    Boeing Navigates 10x Debt-to-Equity and Negative Cash Flow on $89.5B Revenue

    Direct answer

    Boeing remains constrained by substantial debt obligations following multi-year production adjustments, carrying a debt-to-equity ratio of approximately 10x against its $89.5 billion fiscal 2025 revenue base. The company continues to face negative free cash flow generation as commercial manufacturing ramp costs, supply chain bottlenecks, and inventory carrying costs absorb liquidity. With the 10-year Treasury yield trading above 5.04%, refinancing maturities in debt capital markets presents sustained interest expense headwinds relative to unleveraged aerospace peers.
