The profitability analysis reveals that NextNav Inc. (NN) exhibits severely deteriorating margins across all levels—gross, operating, and net. Current gross margin stands at a negative 256.2%, far above its already distressed 10‑year average of -1,102.9% yet still indicating that revenues are insufficient to cover direct costs. Operating margin is even more alarming at -1,535.8% versus a 10‑year average of -3,883.9%, while net margin plunges to -4,138.5% against a historical average of -16,019.6%. Although the percentile rankings suggest NN is performing better than most of its own historical record (95th percentile), the absolute figures are untenable and signal fundamental profitability issues. The sole critical alert—net margin below zero—highlights that the company is generating losses on every dollar of revenue, a red flag for investors. The margin trajectory shows a pattern of consistent decline rather than a temporary dip. Gross margin worsened YoY by -166.1% and over three years by -55.5%, while operating margin improved modestly over three years (+133.5%) but still remains deeply negative, indicating that any short‑term operational efficiencies are insufficient to offset the underlying cost structure. Net margin deteriorated sharply both YoY (-2,341.4%) and over three years (-3,116.7%). This persistent erosion points to structural problems—likely high fixed costs, pricing pressure, or inefficient scale—rather than a cyclical downturn.

NextNav Inc. (NN) exhibits a highly conservative capital structure, with both Debt-to-Equity and Net Debt/EBITDA ratios in negative territory, indicating that cash and equivalents exceed total debt. The current Debt-to-Equity of -3.35x is far below the 10‑year average of 0.09x and sits at the 0th percentile of its historical distribution, reflecting a net‑cash position rather than leverage risk. Similarly, Net Debt/EBITDA stands at -3.9x, an improvement from the prior year’s -3.3x, reinforcing the company’s strong solvency profile. Because leverage metrics are well under typical danger thresholds—such as a Debt-to-Equity above 2.0x or Net Debt/EBITDA exceeding 3.0x—the firm does not approach any concerning leverage levels. No interest coverage data were provided, but the absence of debt‑related alerts and the net‑cash stance suggest that coverage would be comfortably high should interest obligations arise.

NextNav Inc. exhibits severe cash generation deficiencies, posting negative operating cash flow of $-0.1 billion and free cash flow of $-0.1 billion in the most recent period. Both metrics are well below the ten‑year averages (approximately zero) and are trending deteriorating, indicating that core operations are consuming cash rather than producing it. The negative operating cash flow sits at the 0th percentile of its ten‑year range, underscoring an extreme outlier condition. Despite the cash burn, the company’s short‑term liquidity appears robust on paper: the current and quick ratios stand at 12.71×, far exceeding the ten‑year average of 8.31×, and the cash ratio remains healthy at 3.61×. However, these high liquidity metrics are largely a reflection of a sizable balance sheet rather than sustainable cash generation, and they may mask underlying operational weakness if cash reserves are drawn down rapidly.

NextNav Inc.'s earnings quality is compromised by a weak conversion of net income into cash flow. The operating cash flow to net income (OCF/NI) ratio has slipped to 0.27x, well below the 0.8x safety threshold and down 0.10 points year‑over‑year, indicating that roughly only 27% of reported earnings are supported by cash. At the same time, stock‑based compensation (SBC) remains extraordinarily high at 363.8% of revenue, far exceeding the 10% benchmark, which dilutes profitability and raises questions about sustainable earnings generation. While the accrual ratio has improved relative to its ten‑year average, it is still negative (-0.558 versus -0.922), reflecting a reliance on non‑cash accounting items, and capital expenditures are essentially zero, suggesting limited reinvestment but also offering no cushion against future cash needs.
