The full-stack quantum computing company announced results for the quarter ended September 30, 2026. "In the third-quarter, we extended our technology leadership in the critical area of fault-tolerance, added to our customer base, and expanded our routes to market,“ said Rajeeb Hazra, President and Chief Executive Officer of Quantinuum. ”This accelerated momentum is supporting our raised revenue outlook for 2026 and giving us more confidence than ever in the opportunity in front of us."

Financial Results

Cash and cash equivalents were $1.94 billion as of September 30, 2026.

Adjusted EBITDA, Adjusted Gross Margin and Adjusted net loss per share are non-GAAP financial measures. The company said these measures provide investors with additional information useful in evaluating operating performance and trends across periods, and that its results include large non-cash charges it does not consider indicative of ongoing operating performance, principally stock-based compensation recognized on completion of the Reorganization and remeasurement of liability-classified warrants.

Commercial Agreements

Quantinuum said it signed the largest cloud agreement in company history, securing a multi-year extension with a leading global financial institution that includes committed access through Apollo and Nexus.

It also signed with another top 5 global pharmaceuticals company on applying quantum computing and AI to cancer-therapy materials that offer the potential to accelerate drug development and enable more effective treatments, and signed an agreement with GE Vernova to advance application development in superconducting materials. A further deal with Abu Dhabi Maritime Academy and Quincus covers research and applications in maritime logistics.

The company expanded cloud distribution through a new agreement with a leading hyperscaler serving millions of developers and advanced its Oracle partnership by launching a joint beta program for hybrid quantum-AI applications.

On government work, Quantinuum said it is continuing to execute on the DARPA QBI Stage B contract, is actively discussing a Stage C scope of work, and participated in four winning proposals under Phase 1 of the Department of Energy's Genesis Mission.

Internationally, Helios assembly is underway in Singapore ahead of spring 2027 commissioning, and a Reimei system upgrade at RIKEN in Japan is scheduled for completion this month.

Fault-Tolerance Records

Quantinuum said it validated its path to universal, fully fault-tolerant quantum computing by 2029 with back-to-back accuracy world records on Helios using two codes within the same scalable, end-to-end logical architecture. The company reached 99.9995% logical fidelity in October—within Apollo's target range—with an error rate ten times lower than September's record and 100 times lower than the best published result across other hardware modalities. The results also demonstrate what the company described as a significant overhead and scalability advantage.

Sol remains on track for the second half of 2027, with full-scale control-system validation complete and integration and assembly targeted for the first quarter of 2027, ahead of validation and tuning toward 100 logical qubits at a target logical error rate of 10⁻⁵. Apollo remains on track for 2029, supported by design milestones, including validating that the company's cryogenic system can be deployed at the required scale.

The company said it strengthened its manufacturing foundation for future systems through partnerships with GlobalFoundries, Infineon, Honeywell Aerospace and Monarch Quantum, and finalized the CHIPS R&D award as the only trapped-ion company selected.

Software and Platform

Quantinuum announced a multi-generational Nexus roadmap through Apollo, aligning application development and hybrid deployment with successive hardware generations to build what the company believes will be the first developer platform designed for the fault-tolerant era.

A September Nexus release expanded fault-tolerant capabilities by extending Guppy tools for logical-qubit programming and supported error-correction encoding, reducing the need to rewrite applications for specific codes. A planned December release will expand responsive hybrid quantum-classical workflows, supported error-correction codes, and execution analytics for application optimization.

Nexus adoption grew nearly 20% quarter-over-quarter to 215 organizations, and total job submissions increased tenfold in the 12 months through August 2026 compared with the preceding 12-month period.

Ecosystem

Quantinuum introduced QUOPS with Sandia National Laboratories and NVIDIA, benchmarking useful computational scale and speed. The company said it is building industry-wide alignment toward a common standard that supports customer comparisons and purchasing decisions.

It also grew its Q-Net community to more than 800 members, added eight startup partners, and partnered with Singapore's National Quantum Office to organize a global quantum challenge that attracted more than 200 submissions.

Company Background

Quantinuum describes itself as a leading quantum computing company offering a full-stack platform designed to make quantum computing deployable in real-world environments. It has commercially deployed multiple generations of trapped-ion based quantum systems built on the QCCD architecture, which it has implemented with novel designs and capabilities to achieve the industry's highest accuracy levels based on average two-qubit gate fidelity.

The company has active engagements with market leaders across pharmaceuticals, material science, financial services, and government and industrial markets, as well as academic and research institutions globally. It has a global workforce of approximately over 850 employees, with over 70% of its technology team holding PhDs or Master's degrees. Its headquarters is in Broomfield, Colorado, with additional facilities across the United States, United Kingdom, Germany, Japan, Qatar, and Singapore.

Quantinuum said it will host a conference call at 5 PM Eastern time on Thursday, November 5, 2026, to discuss its results and provide a business update. An archive replay of the webcast will be made available on the Quantinuum Investor Relations website following the call and will remain available for one year.
