Firefly Aerospace reported Q4 2020 revenue of $68.06 million with a gross profit of $31.48 million and a gross margin of approximately 46.25%. Operating income for the quarter was $21.99 million, but the bottom line was deeply negative at net income of $107.04 million and an EBITDA of −$57.86 million. The negative net result reflects substantial non-operating charges, including a large total other income/expenses line of −$139.69 million and meaningful interest expense of $26.47 million, underscoring the heavy debt burden and funding costs facing the company in this early-growth phase. Cash flow from operations was modestly positive at $23.04 million, and free cash flow was $20.16 million, supporting a residual cash balance of $161.5 million at period end despite aggressive financing activities in the quarter; total debt stood at $1.946 billion with net debt of $1.814 billion. The balance sheet remains asset-rich (notably $2.53 billion in property, plant and equipment and $279.1 million in intangible assets) with relatively strong liquidity ratios (current ratio ~10.0, quick ratio ~8.7, cash ratio ~5.9), but leverage metrics (debt ratio ~0.75, debt/equity ~3.01) highlight meaningful balance-sheet risk if launch cadence or backlogs do not materialize as planned. While sequential revenue progress is encouraging (QoQ revenue up ~14.6%), the year-over-year decline (~−55.9%) and the outsized non-operating costs imply that near-term profitability hinges on de-leveraging the balance sheet, improving the non-operating cost structure, and achieving sustained launch cadence and backlog conversion. Investors should monitor near-term milestones around Alpha/Eclipse/Blue Ghost development, government program awards, and the company’s progress in refinancing or restructuring its debt stack.
