Karman Reports Record Q3 FY26, but Cash Flow and Valuation Concerns Persist

What happened

Karman Space & Defense announced record third-quarter fiscal 2026 results, marking continued top-line momentum after a 41.7% year-over-year revenue jump in the prior-year quarter. The company's aggressive pursuit of missile and space programs has driven strong revenue growth and a funded backlog above $758 million, but GAAP profitability remains thin and operating cash flow was negative $30.8 million for the first nine months of fiscal 2025. The stock trades at approximately 435 times trailing earnings and over 90 times EV/EBITDA, leaving little margin for execution missteps or defense budget shifts. While the record quarter may validate the company's growth narrative, it does not resolve the high leverage (net debt/EBITDA of 4.5x) or the need for sustained positive free cash flow to support the valuation. Investors should treat the positive headline with skepticism until cash conversion and deleveraging are demonstrated over multiple quarters.

Implication

The stock remains a high-risk, high-reward play on defense spending; a material pullback or clear evidence of cash flow improvement and deleveraging would be needed to revisit the bearish view.

Thesis delta

The new record quarter modestly reduces near-term execution risk but does not materially alter the core concerns: extreme valuation multiples, negative operating cash flow, and elevated leverage. The 'strong sell' thesis remains intact unless subsequent quarters show a decisive improvement in cash conversion and balance sheet strength, or the stock price reverts to a more reasonable multiple.
