Quantum computing is quickly evolving from research to early commercial adoption to address the insatiable need for computing power in the digital age. Even as classical computing continues to advance in energy-efficient performance, the huge computational demands of new applications such as artificial intelligence (“AI”) are making it challenging for classical computing to keep pace. Quantum computing is a fundamentally different approach that allows us to solve entirely new classes of problems in a resource-efficient manner. This paradigm change is being propelled by governments and enterprises, as they recognize quantum computing as a potential key enabler of long-term growth. Quantinuum was built with the mission to lead this transition and play a pivotal role in defining the future of the computing industry. We believe the future of computing will be inherently hybrid, combining classical compute (i.e., CPUs), accelerated compute (i.e., GPUs) and quantum compute (i.e., QPUs). In this architecture, quantum computing will become a foundational layer for solving classes of problems that are fundamentally difficult for classical and accelerated systems alone. We view quantum computing not as a standalone replacement for classical systems, but as a new foundational layer within a hybrid computing stack. In this model, workloads are dynamically orchestrated across computing systems to ensure optimal execution, enabling each class of problem to be solved on the most appropriate computing substrate. Our quantum systems have been designed from the ground up with this hybrid framework in mind. We are already exploring protocols in which our quantum systems will generate data that is subsequently used by AI models to learn and guide the generation of additional data—creating a closedloop feedback system that accelerates discovery across multiple domains. Critically, unlike classical systems, our QPUs produce data that is extremely difficult—if not impossible—to produce classically. This confers a unique advantage: rather than training AI models on data that is broadly available or incrementally derived, we provide novel, highvalue data that would otherwise be prohibitively expensive or altogether unattainable. This capability is driven by our QPU’s ability to accurately model highly complex chemical and physical systems, unlocking insights beyond the reach of traditional computing approaches. While we are in the early stages of commercial growth, our approach has seen recent success as reflected in our bookings. Bookings were $1.3 million for the three months ended March 31, 2026 compared to $1.9 million for the three months ended March 31, 2025. Bookings were $79.3 million for the year ended December 31, 2025. Bookings represent the aggregate dollar value of customer contracts executed during a given period. The ultimate value of our bookings is impacted by new contracts, modifications and terminations. In addition, we are excited by our robust booking pipeline that involves various projects at different stages of the pre-booking process. Quantinuum is a leading quantum computing platform that offers solutions like hardware platforms, developer tools, application libraries and solution-targeted intellectual property (“IP”). Our vertically integrated quantum computing platform combines sophisticated quantum hardware systems and middleware with application software designed to make quantum computing deployable in real-world environments. By enabling hybrid quantum-classical computing workflows with our software, we believe we accelerate the creation of entirely new application categories, such as quantum-enabled AI. Our model of working closely with our customers and partners to build new hardware and software capabilities builds deep, durable relationships that we believe enables Quantinuum to create and capture value. Our selective approach to what we retain as proprietary and what we license as open-source is designed to accelerate developer adoption and ecosystem growth without compromising long-term competitive advantages. Core architectural and system-level IP remain proprietary and protected, while openness is pursued in areas where it strengthens developer engagement. Our QCCD architecture is designed to prioritize accuracy, connectivity and system-level performance over raw gate speed, reflecting our focus on improving time-to-solution for real-world workloads. Quantinuum’s platform is built on the well-established QCCD architecture established in the early 2000s, which we implemented with novel designs and capabilities to achieve the industry’s highest accuracy levels based on Helios’ 99.921% average two-qubit gate fidelity, as of December 31, 2025. In fact, we were the first in the industry to implement logical qubits with a higher accuracy than physical qubits, according to the 2021 Ryan-Anderson et al. Study. Quantinuum has demonstrated technical and operational progress through multiple generations of commercially deployed quantum systems, including H1 (2020), H2 (2023) and Helios (2025). H1 was the first commercial quantum system to demonstrate “Three Nines” (“99.9%”) accuracy for two-qubit gates across all qubit pairs, according to the 2025 Kretschmer et al. Study, and each generation delivered measurable improvements in performance and accuracy. Our team continues to build on these improvements and is working on future system generations, such as Sol, which we expect to introduce in 2027 and anticipate will achieve up to 100 logical qubits (a key milestone in fault-tolerant computing), and Apollo, which we expect to introduce in 2029 and anticipate will achieve 100s of logical qubits. While certain alternative approaches, such as superconducting architectures, may achieve faster individual gate speeds, they often require significantly more operations and higher error-correction overhead to reach a reliable result. We evaluate the performance and commercial readiness of our platform using system-level metrics that we—and our customers—believe are indicative of real-world value and the ability to produce successful outcomes and solutions, rather than early stage and traditional metrics, such as raw qubit count or gate speed. The metrics and performance drivers that best showcase our ability to achieve results include fidelity, number of logical qubits, system scalability, time-to-solution and full-stack performance. We believe these metrics are more directly aligned with customer outcomes and commercial adoption, system cost and the ability to support increasingly complex workloads. Our strategy is hardware-led and software-enhanced, delivering high-accuracy quantum hardware with co-optimized middleware and applications to enable customers to design and implement solutions. Our middleware tools for quantum software developers, like the high-level quantum programming language, Guppy, are designed to make writing and executing quantum programs easy, enabling customers to build high-value solutions. We believe that our software tools across multiple platforms significantly lower the adoption hurdle in application development while creating loyalty to Quantinuum’s platform. We expect that our full-stack offerings, including applications, will help us capitalize on early commercial value as quantum technology is deployed across industries, while preserving significant flexibility to capture value as the industry moves up stack. Quantinuum was formed in 2021 through the combination of Honeywell Quantum Solutions and Cambridge Quantum, uniting innovative quantum hardware expertise with advanced quantum software capabilities. As a controlled affiliate of Honeywell, we inherited discipline and a culture of execution while benefiting from world-class infrastructure, supply-chain relationships and management expertise. Honeywell has also served as both a testing ground for our tools and as an early customer, deploying our solutions in its products. Honeywell has indicated its intent to remain a strategic customer and partner following this offering. We also employ approximately 410 hardware experts and 105 software experts. We have active customer engagements primarily focused across pharmaceuticals, materials science, financial services, government and industrial markets, including with market leaders, such as JPMorgan Chase in financial services, Amgen in pharmaceuticals, Mitsui & Co. in cybersecurity and Honeywell in chemistry, each of whom serves as both a customer and an innovation partner. We believe we are positioned to scale our business using a layered approach to monetization: 1. Grow and maintain market leadership in on-premises and cloud-based quantum solutions, reinforcing scale advantages and customer stickiness. 2. Expand monetization beyond hardware by building high-margin software, applications, and outcome-driven intellectual property that capture recurring value. We believe Quantinuum is uniquely positioned to capture a leading share of value as quantum computing transitions from early adoption to scaled commercial deployment. Key value drivers for our business include: • Differentiated commercially deployed hardware that has the computational power and accuracy to enable a high-value application platform; • Differentiated middleware, co-designed with the hardware platform, that allows software developers to efficiently create and deploy new applications; • Resilient and flexible business model that includes the ability to monetize Quantinuum’s vertical integration while retaining optionality for monetizing software across a broader base of platforms than just our own; • Operational maturity and execution, with demonstrated customer traction and diversified end-market exposure; • Leading technical and business management capabilities with deep expertise across high performance computing hardware and software, as well as manufacturing and operational excellence; and • Culture rooted in innovation, discipline, and strategic collaboration. These factors support our conviction that Quantinuum is well positioned to lead the quantum computing market and to generate durable value for customers, partners and stockholders. Our principal executive offices are located in Broomfield, CO.
