QUBT Bets on Scale as Rising Costs Weigh on Profitability
Read MoreHide Full Article
Key Takeaways
QCi posted $5.6M in Q2 revenues but still recorded a gross loss of about $1.2M.
QCi's operating expenses jumped 114% to $21.8M on payroll, marketing and acquisition costs.
QCi spent about $180M on three buyouts, enhancing capabilities while rising integration and execution risks.
Quantum Computing Inc. (QUBT - Free Report) or QCi faces a key risk as its strong revenue growth has not yet translated into positive profitability. Second-quarter 2026 revenues rose to $5.6 million from just $61,000 a year ago, but the company still reported a gross loss of about $1.2 million.
This indicates that current production volumes are not yet high enough to absorb manufacturing-related fixed costs efficiently. The company is working toward scalable commercial manufacturing and higher production volumes, which could help improve gross margins over time.
Second-quarter operating expenses also surged 114% year over year to $21.8 million, mainly due to higher personnel and payroll costs for research and development, increased sales and marketing spending, and about $7.3 million in acquisition-related transaction expenses.
QCi used approximately $180 million in cash, including transaction expenses, to acquire Luminar Semiconductor, NuCrypt and NHanced Semiconductors during the first half of 2026. These deals not only expanded QCi’s technology and manufacturing capabilities but also introduced integration and execution risks. Increasing production volumes, converting backlog into revenues and controlling expenses will therefore be critical to the company’s path toward profitability.
Peer Update
D-Wave Quantum (QBTS - Free Report) revenues remain uneven because large system contracts still shape reported results, even as recurring commercial usage is improving underneath. Second-quarter 2026 revenues remained essentially flat year over year, while first-half revenues declined to $5.93 million from $18.10 million in the prior-year period, primarily because the year-ago period benefited from a major system sale.
Expense intensity also remains high as D-Wave funds both near-term commercialization and a multi-year technology roadmap. Second-quarter 2026 operating expenses rose 93% year over year, while first-half operating cash outflow increased to $73.5 million from $34.6 million, reflecting a 112% jump.
Rigetti’s (RGTI - Free Report) revenue profile remains tied to the timing of system deliveries and milestone-based development work rather than recurring commercial usage. Revenues reached $5.1 million in the second quarter of 2026, up from $1.8 million a year earlier, driven mainly by sales of 9-qubit Novera systems and related products.
However, concentration remains high, with one customer accounting for 64% of second-quarter 2026 revenues and another for 16%. Rigetti continues to fund a large research and infrastructure program against a small revenue base. Operating expenses rose 48% year over year to $30.3 million, including a 53% increase in R&D to $20.7 million.
