Quantinuum Raises 2026 Revenue Outlook as Losses Widen and Cumulative Revenue Falls
Key Facts
Quantinuum raised its 2026 revenue outlook, citing accelerating commercial momentum that it said strengthened its confidence in the company’s opportunity, as third-quarter results showed a mixed picture of improving margins and widening losses. Chief Executive Rajeev Hazra said the momentum "supports our raised revenue outlook for 2026 and gives us greater confidence than ever in the opportunity ahead of us." But revenue for the first nine months of the year was $22.285 million, compared with $23.908 million in the same period of 2025. The divergence places quarterly performance within an annual trajectory that has not yet translated into cumulative revenue. The company also reported signs of growing use of its Nexus platform and new enterprise contracts, alongside updates to its quantum hardware roadmap.
Gross margin under generally accepted accounting principles turned positive at 33.3% in the third quarter, after registering negative 43.5% in the year-earlier period. Adjusted gross margin was 74.6%, up 853 basis points year over year. By contrast, adjusted EBITDA loss widened to $80 million from $45 million a year earlier. Net loss under generally accepted accounting principles also rose to $118 million, compared with $52 million in the third quarter of 2025. The figures reflect improved margins alongside an increase in operating and net losses.
Cash and cash equivalents totaled $1.94 billion on September 30, 2026, the company said. In August, it said it had more than $2 billion in cash, giving it the capacity to invest to accelerate its business plans while maintaining capital allocation discipline. The company estimated net proceeds after underwriting discounts and commissions at about $1.6288 billion. The reported cash balance provides context for the investment and expansion plans outlined by management.
Commercially, Quantinuum said it signed a multiyear extension of the largest cloud agreement in its history with a global financial institution, providing committed access to Apollo and Nexus. The company did not disclose the value of the agreement or name the institution. It also announced an agreement with a global pharmaceutical company among the sector’s top five to apply quantum computing and artificial intelligence to materials for cancer treatments. It also struck an agreement with GE Vernova to develop applications for superconducting materials. In maritime logistics, it said it had agreed with Abu Dhabi Maritime Academy and Quincus on research and applications in the sector, and launched a joint pilot program with Oracle for hybrid applications combining quantum computing and artificial intelligence.
The company said Nexus adoption grew about 20% quarter over quarter, reaching 215 institutions. Total run requests also increased tenfold in the twelve months through August 2026 compared with the previous twelve months. Quantinuum plans to release a platform update in December that expands hybrid workflows across quantum and classical systems. The update includes support for error-correction codes and execution analytics. The company links rising platform use to the expansion of enterprise applications, while the planned update will give developers additional tools.
On its hardware roadmap, Quantinuum said Sol remains targeted for the second half of 2027, with integration and assembly set to begin in the first quarter of that year. The system targets 100 logical qubits and a logical error rate of 10⁻⁵. Apollo remains targeted for 2029. In October, the company announced that Helios had recorded 99.9995% logical fidelity, within the range of Apollo’s target. It said the error rate in the Helios result was ten times lower than the record set in September and 100 times lower than the best published result across other hardware modalities.
In trading, QNT shares closed at $29.82 in the November 5, 2026 session, down 8.95% for the day. The decline came on the day the company announced third-quarter results, which combined a higher annual revenue outlook and improved margins on one hand with lower cumulative revenue and widening losses on the other.
