Non-GAAP Financial Measures

To supplement Quantinuum’s condensed consolidated financial statements presented in accordance with U.S. generally accepted accounting principles (“GAAP”), the Company uses the following non-GAAP financial measures presented in this release: Adjusted Gross Profit, Adjusted Gross Margin, Adjusted Net Loss, fully distributed, Adjusted EBITDA, and Adjusted Net Loss Per Share, fully distributed.

Adjusted Gross Profit starts with GAAP gross profit and adds back equity compensation and related employer taxes attributable to cost of revenue and depreciation and amortization attributable to cost of revenue.

Adjusted Gross Margin is calculated as Adjusted Gross Profit divided by revenue, net.

Adjusted Net Loss, fully distributed starts with GAAP net loss on an as-converted basis, adjusts for equity compensation and related employer taxes, costs of the initial public offering and the transition to public company reporting, severance expense, the change in fair value of liability-classified warrants, and loss on disposal and write down of assets, and then applies an assumed statutory tax rate to the resulting adjusted pre-tax loss. No tax benefit is recognized in respect of losses subject to a full valuation allowance, and accordingly no tax benefit is reflected in the periods presented.

Adjusted EBITDA starts with Adjusted Net Loss, fully distributed, and further excludes income tax expense, interest income, net, depreciation, and amortization of acquired intangibles.

Adjusted Net Loss Per Share, fully distributed is calculated as Adjusted Net Loss, fully distributed, divided by adjusted shares, fully distributed, basic and diluted, comprising weighted-average Class A common shares outstanding and Common Units of Quantinuum Holdings.

Management believes these measures provide investors with additional information useful in evaluating the Company’s operating performance and trends across periods. Quantinuum’s results include large non-cash charges that management does not consider indicative of ongoing operating performance, principally stock-based compensation recognized on completion of the Reorganization and remeasurement of liability-classified warrants. Both are driven by accounting triggers and external inputs rather than operating activity. As an early commercial-stage business, Quantinuum’s period-to-period results also are affected by the timing of individual contracts. Measures that isolate underlying operating performance from non-cash and transition items help investors assess trends across periods.

Quantinuum’s Up-C structure means that GAAP net loss attributable to Quantinuum Inc. reflects only the Class A share of the economics. Presenting adjusted results on an as-converted, fully distributed basis describes the whole economic enterprise, which is how management assesses performance and how the business is managed. Management uses these measures for internal planning and forecasting, evaluating operating performance, and preparing budgets.

These non-GAAP financial measures are supplemental and are not prepared in accordance with GAAP. They are not intended to be considered in isolation or as a substitute for the most directly comparable financial information prepared in accordance with GAAP. Quantinuum’s non-GAAP measures may differ from similarly titled measures used by other companies and, therefore, may not be comparable. Investors should review the reconciliations and should not rely on any single financial measure to evaluate the Company’s business.

Each non-GAAP financial measure is reconciled to its most directly comparable GAAP financial measure in the tables at the end of this release.

• Roadmap connects application development and deployment with each generation of Quantinuum hardware through Apollo, its universal, fault-tolerant quantum computer planned for 2029.
• Nexus is designed to be the first developer platform that integrates automated error-correction encoding, execution on Quantinuum hardware, and hybrid workflow orchestration.
• Nexus will progressively handle the complexity of fault-tolerant application development and deploy programs that can scale and grow in capability as hardware advances.

BROOMFIELD, Colo. – November 5, 2026 – Quantinuum (NASDAQ: QNT), the leading full-stack quantum computing company, today unveiled a new roadmap to evolve Quantinuum Nexus, its platform as a service, with the aim of delivering the quantum industry’s first developer platform designed for the fault-tolerant era. The roadmap introduces new capabilities with each generation of hardware through Apollo—the company’s first universal, fully fault-tolerant quantum computer planned for 2029—that further simplify and automate how customers build, deploy, and operate quantum applications.

Since its launch in 2024, Nexus has expanded from managing cloud-based quantum workflows to end-to-end application development and deployment, bringing programming, validation, compilation, and execution into one environment. Nexus provides managed access to the software tools and computing resources customers need for hybrid applications and workflows. Nexus offers flexible access and integration options, both in the cloud and on-premises.

Through 2029, successive releases aim to progressively automate and simplify error correction, resource management, orchestration, and deployment, enabling developers to build and integrate increasingly capable applications at the logical level.

By developing its quantum hardware and software together, Quantinuum helps improve application performance across the entire system and turn hardware advances into capabilities customers can use. Nexus is designed to align those capabilities with each hardware generation, giving customers a simpler development path and Quantinuum a stronger platform for winning and expanding user adoption. Developers can already automatically apply supported error-correction techniques to programs and run them on Helios.

Today, Nexus already supports more than 200 organizations, up 45% in 2026, while total job submissions increased tenfold in the 12 months through August 2026 compared with the preceding 12-month period. This growing engagement establishes a customer and developer base that Quantinuum can continue to grow as its hardware matures.

“Our full-stack approach means each advance in hardware can become a capability customers can build on through Nexus,” said Dr. Rajeeb Hazra, Quantinuum CEO. “Our aim is to build the first developer platform specifically for the fault-tolerant era so customers can start developing applications today and carry that investment forward. Nexus is designed to help them deploy applications and hybrid workflows and integrate the platform into their computing environments. As our systems become more capable, our aim is for the applications, workflows, and expertise customers develop in Nexus to become more valuable, giving them a compelling reason to build with Quantinuum and making Nexus an enduring part of their computing environment.”

Building a Developer Platform for the Fault-Tolerant Era

The Nexus roadmap organizes its capabilities around three stages of the application lifecycle—develop, optimize, and deploy—helping customers build hybrid quantum-classical applications that can advance with successive generations of Quantinuum hardware:

• Develop: The roadmap includes pre-built primitives, fault-tolerant libraries, and domain-specific tools that help developers move from individual quantum circuits to complete applications. The platform will progressively automate error-correction encoding, compilation, and resource management, allowing developers to focus more on the application and less on the underlying hardware complexity.
• Optimize: The roadmap outlines tools to analyze runtime behavior, resource requirements, and application performance. Future releases plan to introduce more error suppression, real-time diagnostics, and increasingly automated error recovery to help customers run larger computations and make more efficient use of quantum resources.
• Deploy: Nexus is being designed to coordinate quantum and classical computing across Quantinuum processors, high-performance computing systems, cloud infrastructure, and third-party tools—helping customers integrate quantum workflows into their existing computing environments and deploy larger fault-tolerant applications.

“Quantum computers are on the brink of achieving fault tolerance at scale. It's exciting: we are entering terra incognita for what we can compute. The new challenge is putting our high-level quantum algorithms into the right form to successfully run on error-corrected hardware. Developer platforms like Nexus help us bridge that gap between quantum algorithm design and deployment,” said José Ignacio Latorre, Director of the Centre for Quantum Technologies, Singapore’s flagship national research center for quantum technology.

Optimized specifically for Quantinuum systems, these capabilities are expected to provide a continuous path from early application development on Helios to increasingly capable implementations on Sol and Apollo to help customers carry their investments forward as the hardware advances.

Building the Foundation Today

Quantinuum is already delivering key elements of this approach. Released in September 2026, Guppy FT and Guppy Algorithms expanded Nexus with supported error-correction schemes, fault-tolerant operations, and composable algorithmic building blocks.

Developers can write programs, automatically encode them for supported error-correction schemes, test them in emulation, and execute supported programs on Helios. Advanced users retain the flexibility to customize architectures for specialized applications.

These capabilities establish the foundation for future roadmap releases, including the upcoming December release which is expected to expand hybrid workflows so that applications can respond to quantum results as they become available. It is also expected to add supported error-correction codes and execution analytics to help developers optimize performance.

Connecting Quantum Applications with Enterprise Computing

Researchers and enterprises are already using Nexus to develop applications across chemistry, materials science, life sciences, and AI, while also integrating Nexus into new environments:

• Qubit Pharmaceuticals and CQT used Nexus to execute quantum Monte Carlo experiments on Quantinuum’s System Model H2 and Helios systems.
• Researchers at RIKEN and the University of Tokyo simulated atomic nuclei on Reimei, using Nexus. They also used Nexus to integrate hybrid quantum-HPC workflows to calculate excited-state energies in a model biomolecular system.
• University of Cambridge researchers used Nexus compilation tools to prepare efficient quantum chemistry circuits while Maastricht University researchers used Nexus to simulate, compile, and run a quantum particle tracking algorithm exploring new approaches to reconstructing particle trajectories.
• Unitary Foundation’s Metriq gym uses Nexus to access Quantinuum hardware for reproducible benchmarking across quantum computing platforms.
• Quantinuum is integrating Nexus into Oracle Cloud Infrastructure’s environment to help support the on-prem deployment and integration of Quantinuum’s Helios computer into OCI’s cloud services offering.
