Aerospace Portfolio & Divestment Scenario Workbench
How does carving out an R&D-heavy subsidiary affect pro forma liquidity, burn reduction, and debt-to-EBITDA leverage in corporate aerospace restructuring?
This interactive workbench models the balance-sheet dynamics of aerospace subsidiary carve-outs. When a parent company divests an autonomous or early-stage subsidiary, the transaction contributes pro forma cash from the equity carve-out valuation and eliminates that unit's annual R&D burn rate. In the model's pro forma math, net debt decreases as cash increases, while EBITDA increases by the avoided cash burn, resulting in an improved pro forma Net Debt / EBITDA leverage ratio and wider covenant headroom.
The figures in this workbench are heuristic benchmark fixtures intended for scenario simulation rather than certified SEC financial statements. The calculation adds the entire divested R&D burn directly to baseline EBITDA, omitting transaction friction, carve-out separation costs, residual overhead, and corporate capital gains tax drag. Actual divestitures also involve stranded corporate overhead and delayed closing proceeds.
Try a worked example
In the 'Strategic Presets' toolbar, click 'Broad Non-Core Divest'. The model switches Wisk Aero, Insitu, and Liquid Robotics to Divested status while retaining Aurora Flight Sciences and Millennium Space Systems. Net Liquidity Inflow rises from $1.20B to $1.85B ($1,200M + $400M + $250M), Annual Burn Reduction expands to -$215M/yr ($180M + $20M + $15M), and Rating Covenant Debt / EBITDA drops to 3.45x, delivering +0.25x in leverage headroom.
Dual Balance Sheet Mechanism: Liquidity and Burn Relief
In corporate finance carve-outs, selling a non-core business unit generates two simultaneous balance-sheet effects. First, sale proceeds (valuation multiplied by parent equity stake) enter pro forma cash reserves, directly lowering net debt calculated as core debt obligations minus pro forma cash.
Second, eliminating the subsidiary's annual cash burn reduces consolidated operating expenses. This model credits the saved annual R&D expenditure directly toward pro forma EBITDA, compounding the leverage reduction by simultaneously reducing the numerator and expanding the denominator of the Net Debt / EBITDA ratio.
Strategic Matrix: Core Synergy vs. Cash Drag
The interactive D3 matrix positions business units along two dimensions: strategic defense synergy (horizontal axis, 0 to 100) and annual cash burn (vertical axis). Assets located in the top-left quadrant combine elevated burn with low core defense synergy, making them prime candidates for isolated divestiture or external joint-venture funding without compromising core defense contracting capabilities.
