Key Metrics
Top Statement Risk
Cash burn vs. revenue
Metrics are mathematically derived from official filings.
Cash Conversion Distorted by Non-Cash Items
QUBT's operating cash flow consistently exceeds net losses, with OCF/NI averaging 1.18 in 2026Q2, driven by large working capital outflows and non-cash charges, per quarterly filings.
The gap between net income and operating cash flow is widening, with 2026Q2 showing a $2.1M difference, as working capital changes consumed $9.1M. This suggests that reported losses understate the true cash burn, as inventory build-up and receivables expansion are not yet reflected in earnings. Investors should monitor whether this trend persists as revenue scales.
FCF Burn Accelerates Despite Revenue Growth
Free cash flow deteriorated to -$16.5M in 2026Q2, a 132% increase from the prior quarter, with FCF margin at -3.0% of revenue, per the cash flow statement.
Despite an 82.8% revenue surge, FCF losses are widening faster than sales, indicating that the hardware pivot is consuming cash at an unsustainable rate. The negative FCF margin, though improved from -116.8% in 2025Q2, remains deeply negative, suggesting that the company is far from self-funding. The trajectory implies continued reliance on external capital.
Capital Intensity Rises with Hardware Shift
CapEx jumped to $2.7M in 2026Q2, representing 48% of revenue, up from 5.8% in 2025Q4, reflecting increased investment in nanophotonic manufacturing, as reported in quarterly data.
The sharp increase in capital intensity aligns with the strategic pivot to proprietary hardware, but it also signals that QUBT is transitioning from a software-like model to a capital-heavy one. This shift may pressure future cash flows, as depreciation and maintenance costs are likely to rise. The elevated CapEx/Revenue ratio suggests that scaling production will require sustained investment.
Working Capital Drain Signals Scaling Pains
Working capital changes consumed $9.1M in 2026Q2, a 60% increase from the prior quarter, indicating significant inventory build-up and receivables growth, per the cash flow statement.
The growing working capital outflow suggests that QUBT is funding revenue growth through inventory and receivables, which may strain liquidity if not managed. This pattern is typical of hardware companies scaling production, but it also implies that cash conversion will lag revenue recognition. Investors should watch for any signs of inventory obsolescence or collection issues.
Acquisition Activity Distorts Cash Flow
QUBT reported a $99.9M acquisition outflow in 2026Q2, offset by a $99.9M inflow in 2026Q1, per the cash flow statement, suggesting a significant M&A transaction.
The large acquisition-related cash flows are likely tied to the QPhoton acquisition or similar deals, but the net effect over two quarters is neutral. This activity obscures the underlying operational burn, which remains the primary cash drain. The lack of dividends or buybacks indicates that all capital is being reinvested into growth, but the sustainability of this strategy depends on future revenue generation.
Cash Position vs. Burn Rate Contradiction
The reported $737.88M cash balance against a $16.5M quarterly FCF burn implies a 44-quarter runway, but this figure is highly anomalous relative to peers, per the provided data.
If the cash balance is accurate, QUBT has ample liquidity to fund operations for years, which could support its hardware pivot. However, the discrepancy between this cash level and the company's revenue scale suggests either a recent massive capital raise or a data error. Investors should verify this figure, as it materially changes the risk profile; if overstated, the company faces near-term insolvency risk given the accelerating burn.
