Quantum Computing Inc. slips after hours despite record revenue; Quantum Corp. is a storage firm, not a quantum stock
QUBT's Q3 revenue jumped to $9.5M but its loss was wider than expected. The 13% and 18% after-hours gains in the original topic don't match reported figures.
Key numbers
| QUBT Q3 2026 revenue | $9.5M |
|---|---|
| QUBT Q3 loss per share | $0.07 |
| QUBT Nov 9 close | $6.86 |

What happened
Quantum Computing Inc. (QUBT) reported third-quarter 2026 results after the close on 9 November. Revenue rose to a record $9.5 million from $384,000 a year earlier, but the loss of $0.07 a share was wider than the $0.04 analysts expected. The stock had closed at $6.86, up 8.37% on the day, then slipped roughly 3% to 4% after hours, to about $6.63. Separately, Quantum Corp. (QMCO), a data-storage company, reported fiscal Q2 revenue up about 43% to $89.6 million and a record backlog of nearly $100 million. We could not verify the 13% (QUBT) and 18% (QMCO) after-hours gains in the original topic.
Why it matters
Investors treating the two Quantum names as one trade could be misled. QUBT is a quantum computing company whose revenue growth is driven by acquisitions, with losses widening. Quantum Corp. sells data-storage products, so its results say little about quantum computing demand. The after-hours reaction shows investors are still weighing QUBT's growth against its losses.
