Rhea-AI Filing Summary

Rigetti Computing, Inc. is an early-stage quantum computing company focused on superconducting, multi-chip processors delivered via cloud services and on-premises quantum processing units (QPUs). It operates its own Fab-1 fabrication facility and emphasizes modular “chiplet” architectures to scale qubit counts.

Recent systems include the 36‑qubit Cepheus‑1‑36Q with a reported 99.6% median two‑qubit gate fidelity and a 76‑nanosecond median gate time, and a 108‑qubit Cepheus‑1‑108Q using twelve 9‑qubit chiplets. Internal testing has shown two‑qubit fidelities up to 99.9% on prototype platforms.

The company is building a business model around QPU sales, quantum computing‑as‑a‑service and development contracts, with partners such as AWS, Microsoft Azure and government agencies. It reported a net loss of $216.2 million in 2025 and an accumulated deficit of $771.0 million, and expects continued losses as it invests heavily in R&D and manufacturing.

Rigetti entered a Collaboration Agreement with Quanta, under which each party plans to invest at least $250 million in quantum computing over five years, and Quanta bought approximately $35 million of Rigetti common stock. The company also received an $8.4 million purchase order to deliver a 108‑qubit system to India’s C‑DAC and continues to highlight significant technical and commercialization risks, including the possibility that quantum advantage or large‑scale fault‑tolerant systems may not be achieved on its anticipated timeline or at all.

Summary Risk Factors

Our business is subject to a number of risks of which you should be aware before making a decision to invest in our securities. These known and unknown risks, uncertainties and other factors include, without limitation:

We are in our early stages and have a limited operating history, which makes it difficult to forecast our future results of operations. We have in the past failed to meet publicly announced milestones and may fail to meet projected technological milestones in the future. In addition, we have in the past changed our technology roadmap, including the anticipated milestones and timing thereof.
We will require a significant amount of cash for expenditures as we invest in ongoing research and development and business operations and may need additional capital sooner than planned. If we are unable to raise additional funding when needed, we may be required to delay, limit or substantially reduce our quantum computing development efforts.
We may not be able to scale our business quickly enough to meet customer and market demand, which would result in lower profitability or cause us to fail to execute on our business strategies.
Even if the market in which we compete achieves its anticipated growth levels, our business could fail to grow at similar rates, if at all.
We may not manage growth effectively, including with respect to our employee base and managing our operations successfully.
Our ability to use net operating loss carryforwards and other tax attributes may be limited.
We face significant technical and engineering challenges in completing the development of our quantum computers, producing our quantum computers at scale, achieving our targeted performance milestones and realizing quantum advantage, any of which is not accomplished would adversely impact our business.
We may expend our resources to pursue particular products, designs, sectors or investments and we may fail to capitalize on such products, designs, sectors or investments and/or forego other products, designs, sectors or investments that have been more profitable or for which there may have been a greater likelihood of success.
The quantum computing industry is competitive on a global scale and we may not be successful in competing in this industry.
We depend on a limited number of customers for a significant percentage of our revenue and the loss or temporary loss of a major customer for any reason could harm our financial condition.
A significant portion of our revenue depends on contracts with the public sector, and our failure to receive and maintain government contracts or changes in the contracting or fiscal policies of the public sector could have a material adverse effect on our business.
Our business is currently dependent upon our relationship with our cloud providers. There are no assurances that we will be able to commercialize quantum computers from our relationships with cloud providers.
We depend on certain suppliers to source products. Failure to maintain our relationship with any of these suppliers could have a material adverse effect on our business.
We have and may in the future enter into collaboration agreements and similar arrangements with third parties for the manufacturing of our products, and these arrangements may never achieve their goals.
Our ability to compete successfully depends on continuous innovation, timely execution of our strategy and achieving cost reduction, and failure to do so could render our quantum computing systems obsolete or less competitive.
We could suffer disruptions, outages, defects and other performance and quality problems with our quantum computing systems, our production technology partners or with the public cloud, data centers and internet infrastructure on which we rely.
We are highly dependent on our ability to attract and retain senior executive leadership and other key employees, such as quantum physicists, software engineers and other key technical employees, which is critical to our success.

PART I

ITEM 1.BUSINESS

Overview

Our mission is to build the world’s most powerful computers to help solve humanity’s most important and pressing problems. Our strategy is to be at the forefront of superconducting quantum computing.

Classical computers are plateauing, Moore’s law has slowed, returns for parallelization are diminishing and energy requirements can’t keep up. Today, many of the world’s most important computational challenges remain intractable, lying beyond the capabilities of traditional supercomputers and cloud infrastructure. We build and operate quantum computers. We believe quantum computing represents one of the most transformative emerging capabilities in the world today. By leveraging quantum mechanics, our quantum computers process information in fundamentally new, more powerful ways compared to classical computing with meaningful power efficiency. When scaled, we believe these systems are poised to solve problems of staggering computational complexity at unprecedented speed.

The availability of scalable quantum computers is expected to enable scientists and engineers to address problems in areas like climate change, fusion energy, quantitative finance, drug development and discovery, materials science, and artificial intelligence (“AI”). Our quantum computers are based on superconducting qubits, which we believe is the leading quantum computing modality based on their fast gate speeds and defined pathway to scaling. Our quantum computers currently achieve gate speeds of 50-70 nanoseconds, which is about 1,000 times faster than other modalities such as trapped ions or pure atoms based on publicly available information. We have developed the world’s first multi-chip quantum processor for scalable quantum computing systems. We expect this patented and patent pending modular chip architecture to be the building block for new generations of quantum processors that we expect to achieve an advantage over classical computers. We have already demonstrated the potential of our modular chip architecture with the launch of Cepheus-1-36Q, which is based on four 9-qubit “chiplets” tiled together.

We are a vertically integrated company. We own and operate Fab-1, a wafer fabrication facility dedicated to prototyping and producing our quantum processors. Through Fab-1, we own the means of production of our breakthrough multi-chip quantum processor technology. We leverage our chips through a full-stack product development approach, from quantum chip design and manufacturing through cloud delivery. We believe this full-stack development approach offers both the fastest and lowest risk path to building commercially valuable quantum computers.

We have been deploying our quantum computers to end users over the cloud since 2017. We offer our full-stack quantum computing platform as a cloud service to a wide range of end-users, directly through our Rigetti Quantum Cloud Services (QCS®) platform, and also through public cloud service providers.

We began selling quantum computers to end users in 2023. In December 2023, we launched the Novera™ QPU, our first commercially available quantum processing unit (“QPU”), which includes a 9-qubit chip that features tunable couplers for two-qubit operations and a 5-qubit chip for testing single-qubit operations. The Novera QPU is based on our fourth generation Ankaa™-class architecture. In December 2024, we sold a Novera QPU to Montana State University, which was our first QPU delivered to an academic institution. In 2025, we received purchase orders for two Novera systems totaling approximately $5.7 million. Both systems are upgradeable, allowing the customers to increase the system qubit count for more complex computations and research.

In the fourth quarter of 2024, we announced the public launch of our 84-qubit Ankaa-3 system, which featured an extensive hardware redesign. We achieved a key two-qubit gate fidelity milestone with Ankaa-3: successfully halving error rates in 2024 to achieve a 99.0% median two-qubit gate fidelity based on our internal testing. For information on gate fidelity, see “—Our Technology—Our Superconducting Quantum Processors—Fidelity.”

In the second quarter of 2025, we announced the public launch of our 36-qubit Cepheus-1-36Q system, our newest flagship quantum computer that utilizes our modular chip architecture and demonstrates our path to scaling to higher qubit count and higher performing systems. Made of four 9-qubit “chiplets,” we believe that Cepheus-1-36Q is the industry’s largest multi-chip quantum computer. As of January 2026, we achieved a 99.6% median two-qubit gate fidelity (based on internal testing) with Cepheus-1-36Q, successfully halving our error rate from our previous, single-chip 84-qubit Ankaa-3 system.

Ankaa-3 and Cepheus-1-36Q are available to our partners via the Rigetti QCS platform. Cepheus-1-36Q is intended to enable users to operate our universal CZ gates for a wide range of algorithmic research, with a median gate time of 76 nanoseconds. Our CZ gates are designed to be optimized for fast gate times while reducing coherent errors, which improves fidelity and is key for executing quantum error correction techniques. Cepheus-1-36Q features scalable chip architecture with 3D signal delivery while incorporating enhancements to key technologies, such as enhanced intermodule coupler design to enable higher performance.

Table of Contents

Leveraging our full-stack platform and in-house quantum foundry capabilities, we believe that Cepheus-1-36Q demonstrates our ability to deliver increasingly higher performance quantum computers with larger qubit counts using our proprietary chiplet-based architecture. We have developed strong customer relationships and collaborative partnerships for the purpose of accelerating the development of key technologies for high-value use cases to potentially unlock strategic market opportunities.

Our partners and customers include commercial enterprises such as Amazon Web Services (“AWS”) Standard Chartered Bank and Moody’s, along with U.S. government organizations such as Defense Advanced Research Projects Agency (“DARPA”), Department of Energy (“DOE”), and Air Force Research Laboratory (“AFRL”), and international government entities such as India’s Centre for Development of Advanced Computing (“C-DAC”), India’s premier R&D organization of the Ministry of Electronics and Information Technology. In April 2025, Rigetti UK Limited, our wholly owned subsidiary, announced that it was selected as one of the winners of Innovate UK’s Quantum Missions Pilot Competition to advance quantum error correction capabilities on superconducting quantum computers. As part of the project, we are upgrading our existing quantum computer hosted at the UK’s National Quantum Computing Centre to a larger 36-qubit quantum processing unit and integrating it with Riverlane Ltd.’s quantum error correction stack.

In January 2026, Rigetti Computing India P L, a wholly owned subsidiary of Rigetti Computing, Inc., announced that it received an $8.4 million purchase order to deliver a 108-qubit quantum computer to C-DAC. The system will be installed on-premises at C-DAC’s Bengaluru center and is expected to be deployed in the second half of 2026.

We are focused on continuing to improve our system performance. We recently achieved a two-qubit gate fidelity as high as 99.9% at 28 nanosecond gate speed on a prototype platform by using a new proprietary adiabatic CZ scheme. We continue to be at 99.9% one-qubit gate fidelity. In January 2026, we announced achievement of a median two-qubit gate fidelity (based on internal testing) of 99.7% on our 9-qubit system, 99.6% on our 36-qubit system and 99.0% on our 108-qubit system (Cepheus-1-108Q). Cepheus-1-108Q is based on twelve 9-qubit chiplets and leverages our proprietary modular chip architecture. We are enabled by a deep technical team that includes global experts in quantum chip design and manufacturing, quantum computing systems architecture, quantum software, and quantum algorithms and applications.

Powered by the production of our scalable multi-chip quantum processors in Fab-1 and our full-stack product development approach, we are working to develop quantum computing systems that demonstrate clear performance advantages over classical computing alternatives for multiple high-impact application areas.

Quanta Collaboration Agreement

In February 2025, we entered into a Collaboration Agreement (the “Collaboration Agreement”) with Quanta, whereby the parties may enter into written statements of work from time to time pursuant to which Quanta will develop Covered Components listed in such statement of work that meet the specifications and requirements provided by us. “Covered Components” may include control systems, dilution refrigerators, flexible cables, and select other non-QPU components suitable for our quantum computing products. In addition, the parties have each agreed to invest at least $250 million over the next five years in the field of quantum computing (and Quanta’s investment will be towards personnel and capital expenditures for developing products and services and manufacturing capability in furtherance of our product roadmap). Further, in connection with the Collaboration Agreement, in April 2025 Quanta purchased approximately $35 million of shares of Common Stock at approximately $11.59 per share, pursuant to a securities purchase agreement.

Potential Market Opportunity

Demand for computing power capable of solving computationally complex problems is increasing. Many of these types of problems are approached through the use of High-Performance Computing (“HPC”), which relies primarily on large classical computers located either in the cloud or on-premises. We believe that quantum computers will be able to solve many computational problems with greater speed and at a lower cost than today’s high-performance computers, thereby unlocking considerable value for the users of current HPC systems. Furthermore, we believe that quantum computing will be applicable to many use cases that today lie within the realm of the much larger cloud computing market.

Advanced scientific and technical computing applied in fields like drug discovery, materials science, computational fluid dynamics, machine learning, and quantitative finance have underpinned many of society’s greatest scientific and industrial advancements over the past half-century. Yet, despite the availability of the latest cloud and supercomputing capabilities, these and many other fields remain constrained by the intractable nature of their thorniest problems. Typically, the computational limits of classical computers are reached because of either the size or complexity of the required calculations. In certain cases, algorithms have been developed that in theory solve a particular computation problem; however, classical computers are limited in their ability to implement and process such algorithms.

Table of Contents

For decades, classical computing power increased exponentially as the number of transistors on a microchip were doubling about every two years, while the cost of computing simultaneously decreased significantly. Over the past ten years, this rate of progress in classical computing power has significantly slowed as physical limits on the miniaturization of transistors in nano-scale devices are being reached.

Stages of Evolution of Quantum Computing Maturation

We believe that market demand for our quantum computers will grow in phases that map to the increasing capabilities of our commercially available quantum computing systems similar to those of classical computer technology. With each new phase, we expect quantum computers to solve an ever-increasing breadth of high-impact commercial problems and to do so with greater speed and accuracy. Qubits do not need the latest semiconductor lithography node and, in fact, can be made using 1990’s era lithography.

Quantum Advantage (“QA”)

We define QA as the point at which quantum computers can solve a practical problem that would be physically impossible to solve on a classical computer. We believe that a quantum computer with over 1,000 qubits with a two-qubit gate fidelity of above 99.9% and gate speed of less than 50 nanoseconds is needed to achieve QA.

Upon achievement of QA, we believe a quantum computer would be suitable for many applications, including quantum machine learning, quantum simulation, and quantum optimization problems. If QA were to be demonstrated, we would expect a meaningful number of new potential clients to emerge, as the range and value of the problems that would be addressable by quantum computing systems would significantly increase.

Large-Scale Fault Tolerant Quantum Computing (“LFTQC”)

We will consider the phase of LFTQC to begin if and when quantum computing systems are available with hundreds of logical qubits, which can be universally controlled and measured with substantially error-free operation through the full course of a quantum computation. It is currently believed in the quantum computing industry that this is likely to require systems with 10,000 to 1,000,000 physical qubits. We believe our multi-chip architecture provides a pathway to scale up to these large systems.

We anticipate the beginning of the large-scale fault tolerant phase to be roughly a decade away. As quantum computing matures through this phase, systems would likely continue to grow in scale and performance, culminating in full-scale fault tolerance that operates using potentially thousands of effectively logical qubits. This ultimate goal of full-scale fault tolerance represents the largest commercial opportunity.

Business Strategy

Our approach to developing and sustaining what we believe is a strong competitive advantage relies on a six-pronged strategy:

Develop superconducting gate-based quantum computers based on advantages in gate speeds and scalability. We believe the superconducting modality of quantum computing offers advantages in scalability and gate speeds as opposed to other modalities. Based on publicly available information, superconducting quantum computers have gate speeds that are about 1,000 times faster than other modalities such as trapped ions and pure atoms. We believe fast gate speeds are important because they enable quantum computers to operate efficiently in a hybrid computing environment. We also believe that a superconducting modality utilizing a multi-chip architecture provides a defined pathway to scaling up to the large systems needed for LFTQC.
Create high-performance quantum computing systems through full-stack product development. From the outset, we have approached the market opportunity with a strategy to build quantum computers, the superconducting processors that power them, and the software required to access and program these systems. We believe that vertical integration, from chip manufacturing through sales of QPUs and cloud delivery, unlocks the fastest and lowest risk path to broad commercialization and the largest, long-term market opportunity. This was underscored by our announcement of the industry’s first multi-chip quantum processor for scalable quantum computers, a capability realized through many innovations from Fab-1.
Utilize an open modular architecture that allows for integration of innovative solutions. We have adopted an open modular architecture for our quantum computers that allows for integration of innovative solutions developed by third parties into our technology stack. We believe that customers value the flexibility provided by an open modular architecture and that our approach will provide us with an advantage over competitors who utilize a closed architecture.

Provide broad access to our quantum computers. We sold our first QPU in 2023 and in December 2023 launched Novera™, our first commercially available QPU, which features a 9-qubit chip with tunable couplers for fast two-qubit operations and a 5-qubit chip for testing single-qubit operations. In 2021, we began selling full-scale quantum computing systems, supporting national laboratories and quantum computing centers. We have been providing cloud access to our quantum computers since 2017 and have since expanded the availability of our machines through distribution agreements with other solution providers, including Amazon Bracket among others. Cloud services efficiently simplify access to our quantum computers and allow for pricing that enables a broad range of scientific, commercial, and academic developers to readily participate in the development of quantum computing algorithms, applications and software development tools. Collectively, these cloud services provide a range of choices and capabilities designed to meet the diverse needs of large and small organizations alike.
Develop deep partnerships that accelerate the development and commercialization of quantum computing. We have formed commercial partnerships with business and government entities that are designed to advance their mutual understanding of the opportunities, challenges, and solutions necessary for quantum computing to excel in specific real-world applications. Examples of these partnerships include our contracted relationships with DARPA, the DOE’s Fermi National Accelerator Laboratory (“Fermilab”) and AFRL. We believe these types of highly collaborative, multi-year relationships will yield specialized and proprietary market insights and technological advancements. We expect the number and scope of these types of partnerships to expand as the capabilities of our quantum computers continue to grow.
Advance our technology leadership position. We have invested heavily in a world-class and multidisciplinary team of scientists, hardware and software engineers, system designers and algorithm and application developers to rapidly innovate, invent, engineer, and commercialize our quantum computing technologies. We have also developed numerous proprietary technologies required to create quantum computing chips, quantum computer systems, software and cloud-based services and we rigorously protect our unique intellectual property through a portfolio of 121 patents issued and 160 patents pending as of December 31, 2025. We intend to continue deeply investing in finding and fostering the talent required to remain at the forefront of quantum computing innovation, while protecting our growing base of intellectual property.

We believe that we will be able to achieve our plans described above and elsewhere in this Annual Report on Form 10-K; however, we face various risks and uncertainties relating to our business that could cause actual results to differ materially from our expectations stated herein. This Annual Report on Form 10-K, including this Business Section, should be read in conjunction with the section entitled “Risk Factors” in Part I, Item 1A of this Annual Report on Form 10-K.

Business Model & Services

Currently, we generate the majority of our revenues from technology development contracts with various partners. We believe our longer-term business model will be more weighted towards QPU sales and recurring revenues generated from quantum computing systems made accessible via the cloud in the form of QCaaS and QCS services.

Rigetti Quantum Processing Units

Our QPUs contain fabricated silicon-based chips featuring superconducting qubits. These high-performance chips provide fast gate times, low latency conditional logic, and fast program execution times. Our QPUs are designed and fabricated at Fab-1, leveraging novel manufacturing methods to create state-of-the art superconducting qubits.

Novera™, our first commercially available QPU, includes a 9-qubit chip that features tunable couplers for fast two-qubit operations and a 5-qubit chip for testing single-qubit operations. The Novera™ QPU is based on our fourth generation Ankaa-class architecture. We announced our most technically advanced QPU yet based on our proprietary chiplet-based architecture, the 36-qubit Cepheus-1-36Q system, which we believe is the industry’s largest multi-chip quantum computer. We have also released our 84-qubit Ankaa-3 quantum computer, which is available on Amazon Braket. We intend to design and fabricate more advanced QPUs in the future with improved fidelities, faster gate speeds and higher qubit counts. We believe these anticipated improvements and advances in technology will hopefully lead to QA and LFTQC in the future.

Quantum Computing as a Service (QCaaS)

We sell access to our quantum computers through cloud-based services, commonly referred to as QCaaS. This approach enables us to serve a wide range of customers without the complexity and cost associated with shipping, operating and servicing complex and cryogenic computing equipment on customer premises.

Rigetti Quantum Cloud Services

Rigetti Quantum Cloud Services (“QCS”) is a proprietary platform to deliver high-performance quantum computing over the cloud. QCS features a hybrid quantum-classical computing environment that incorporates our quantum computers operating in tandem with cloud infrastructure. It provides support for a broad range of programming capabilities, the ability to integrate over public or private clouds, and high-speed connectivity to auxiliary classical computing resources.

The product is designed to meet the needs of a diverse set of customers that all benefit from the high-performance nature of its core computational capabilities. Central to QCS are two very powerful sets of technologies developed by us, our QPUs, described above, and our quantum operating system, as described below:

Quantum Operating System Software

QCS’s computing environment is powered by a distributed quantum operating system that natively supports both public and private cloud architectures.

The operating system software includes a rich set of quantum application and software development tools designed to unlock the capabilities of the quantum computing ecosystem by:

Enabling customers to access our QPUs through a broad range of quantum application software, development frameworks and algorithm libraries;
Providing software and algorithm developers with the performance and fine-grained control required to expedite a new era of computational breakthroughs; and
Facilitating the implementation of high performance public and private clouds with ultra-low latency connectivity between classical hardware and our QPUs.

QCS Outpost

Customers who purchase an on-premises quantum system from us also have access to QCS Outpost, our distributed software environment for operating, administering, and monitoring the overall system. In addition, QCS Outpost includes utilities for QPU characterization and calibration, user access management, quantum program compilation, scheduling, and execution.

QCS Outpost also serves as the foundation for integrating with other systems, in particular high-performance computing systems, and can be accessed through a variety of tools and web-based services as well as through software development kits (SDKs) that support Python, C, and Rust.

Direct QCaaS Distribution

We provide access on a commercial basis to our quantum computers over QCS, directly engaging with enterprises and government organizations making significant investments in quantum computing research, development, and readiness.

We believe many of these customers will have performance, customization and integration requirements best met by our ability to engage deeply and directly with these kinds of clients. We believe our full-stack product development approach, and strategy of forging collaborative customer partnerships positions us to be a highly valued and long-term provider of quantum computing services to these organizations.

To date, these direct customer relationships have been with customers using QCS for general quantum computing research, algorithm development, algorithm benchmarking and software development activities. They represent a cross section of industries, government agencies and partners in the quantum computing ecosystem.

Indirect QCaaS Distribution

There are a large and growing number of providers of classical computing services over the cloud. This creates an opportunity for us to efficiently reach a broad set of end-users, indirectly, by partnering with cloud computing service providers, who in turn sell access to our quantum computer systems to their own customers.

The indirect distribution model is enabled by the same QCS platform used in the direct distribution model, allowing us to address the needs of customers in different market segments. In this instance, we can capitalize on our full-stack product development capabilities to meet the unique requirements of cloud-service providers. For example, one cloud provider or HPC operator might need deep and high-performance integration with a specific machine learning service they provide, while another might desire a fast and easy way for small customers to be introduced to quantum computing. We have distribution agreements with Amazon’s Braket service and Microsoft’s Azure Quantum Service, providing access to our quantum computing systems to AWS and Azure customers.

Key Applications

Quantum computing is expected to drive value across many different applications and industries. We believe that many of the principal benefits in these areas will spring from four different types of computational problems that are particularly well suited to quantum computing: optimization, machine learning, simulation and quantum mechanical system simulation.

Optimization

Discrete optimization, also known as combinatorial optimization, focuses on problems where variables are restricted to specific, discrete values (e.g., 0 or 1). Unlike continuous variables, which can assume any value, discrete variables are constrained. The primary goal of this field is to determine the optimal assignment of values to these discrete variables to solve a given problem. This is typically achieved by formulating the problem around an objective function—a mathematical construct that one seeks to either minimize or maximize through the selection of the variables' values.

Such optimization problems are ubiquitous, spanning areas like logistics, routing, manufacturing, scheduling, telecommunication, energy, chemistry, biology, physics, finance, and basic science. For example, in financial services, optimization can be applied to portfolio management, algorithmic trading, and risk assessment. In telecommunications, optimization can be applied to call routing and network capacity planning. In manufacturing, optimization can help with workforce, warehouses, and supply chain planning. In transport, there are logistics applications like fleet routing, driver scheduling, and package loading and delivery that can benefit from further optimization. In energy, optimization can be applied to effectively deliver power distribution over the grid. In biology, optimization can be applied to accelerate or improve drug discovery processes.

Optimization problems can be computationally intensive, and the run-time required for classical solvers to identify an optimal solution increases exponentially with the number of variables. For problems of meaningful scale, obtaining a provably optimal solution is effectively infeasible, necessitating the use of estimated or approximate solutions. As a result, optimization in practice focuses on identifying the best attainable solution within practical run-time limitations, which are shaped by industry-specific factors. Because even marginal improvements in solution quality can translate into meaningful gains in areas such as cost, timing, or resource allocation, there is demand for the development of more efficient and accurate optimization methods.

Quantum computers introduce a fundamentally different computational model that extends beyond classical computer systems. It leverages distinctive mechanisms—such as entanglement, superposition, and interference—to enable new algorithmic strategies for addressing complex optimization problems. These mechanisms underpin a range of quantum algorithmic frameworks, including quantum adiabaticity, variational quantum circuits, and quantum interferometry, among others, which may be applied in optimization contexts. While certain quantum optimization algorithms are designed to offer mathematical performance guarantees, others are developed as heuristics. Whether quantum optimization algorithms can outperform current state-of-the-art classical methods in terms of accuracy or run-time remains an open question.

We have conducted research in the field of quantum optimization for several years, pioneering original work and collaborating with experts to develop, understand, benchmark, and apply quantum optimization algorithms. We have examined the role of entanglement in quantum optimization, including its tradeoff with hardware noise, and have identified instances in which quantum optimization exhibits capabilities that exceed those of classical approaches. We have invented several quantum algorithms, and in 2025 we unified these techniques under the umbrella of quantum preconditioning. Quantum preconditioning is a quantum-boosted heuristic algorithm, which uses the quantum computer to modify a problem in a manner that makes it more readily solvable on a classical solver. We investigated the potential for QA on standard benchmark problems as well as an energy-grid optimization problem, targeting the QA window described above. We have also investigated other approaches to optimization, such as a qubit-efficient solver, a quantum-based multilevel approach, and quantum algorithms with co-designed circuits or logical gates. In addition to numerous peer-reviewed publications in leading journals, our works have been presented at a number of conferences nationally and internationally.

Our expertise in quantum optimization has been recognized through our participation in U.S. government programs such as DOD’s DARPA ONISQ (2020-2024), DOD’s DARPA IMPAQT (2023-2024), and DOE’s National Quantum Initiative with the superconducting quantum materials and systems center.

Machine Learning

Machine learning is a well-established computer science field that is already having a transformative impact on a myriad of markets today. At the core of any machine learning algorithm is a series of computations, typically linear algebra, applied to vast amounts of data that can reliably classify objects in pictures and make data-driven forecasts, for example. Today, cloud computing and HPC have been the predominant sources of the computational capabilities required to create and deploy effective machine learning algorithms, models and data analysis applications.

When faced with increasing amounts of data and while trying to grasp more complex patterns, the energy consumption of HPC-powered machine learning systems may become exorbitant due to computational and cooling demands. For that reason, computer scientists have looked toward the promise of higher computational efficiency of quantum computers, and the development of quantum machine learning (“QML”) algorithms, as a means of both accelerating current machine learning applications and creating new approaches that are currently impossible with classical computers and may lead to more efficient and accurate models.

Given these factors, the emerging field of QML is the focus of much of the current quantum computing research. We already see emerging machine learning algorithms that take advantage of the unique capabilities of quantum computing to tackle the complex linear algebra problems at the heart of many machine learning tasks. In fact, recent research has emerged demonstrating that quantum algorithms could work better than classical ones for critical machine learning classification problems. As algorithmic research continues to progress, some of these quantum algorithms are improving to the point where their benefits may be realized on smaller scale quantum computers.

Research has also demonstrated the promising application of QML, for Generative Adversarial Networks, (“GANs”), a deep learning technique where a neural network is used to generate highly accurate and new examples that could plausibly have come from an original dataset. The potential utilization of quantum computing for GANs alone is far-reaching and could be impactful in large markets like:

Healthcare – for medical image analysis used to detect and categorize tumors and predict their growth;
Drug discovery – for generating molecular structure candidates for medicines to target or cure diseases;

Finance and banking – for creating models that can detect financial fraud based upon predictive patterns rather than rules determined by previously observed behaviors; and
Defense and intelligence – for reliably enhancing low resolution satellite imagery into high resolution photography.

The following are examples of our work related to machine learning:

In November 2023, we were awarded an Innovate UK grant as part of the Feasibility Studies in Quantum Computing Applications competition. Joining us in this work were Amazon Web Services (AWS), Imperial College London, and Standard Chartered. The consortium aimed to use quantum computing to improve current classical machine learning techniques used by financial institutions to analyze complex data streams. Financial institutions need to continuously interpret complex data streams to extract information necessary for providing accurate credit risk evaluation, managing market-making services, and predicting emissions in the context of green finance, among other things. Classical machine learning techniques used to assist and provide insights to these services have limitations as these data streams are, in general, complex. Combining quantum computing with classical machine learning methodology could offer more powerful resources for processing these data streams, given the potential for quantum computers to process some types of information more efficiently than with classical resources alone.

In October 2023, we were awarded a separate Innovate UK grant as part of the Feasibility Studies in Quantum Computing Applications competition. Joining us in this work were HSBC, the Quantum Software Lab (QSL) based at the University of Edinburgh, and the National Quantum Computing Centre (NQCC). Together, the consortium aimed to enhance existing anti-money laundering techniques by using quantum machine learning techniques with the goal of improving the performance of current-state-of-the-art machine learning algorithms. In this work, the consortium aimed to extend current anomaly detection quantum machine learning models to detect anomalous behavior indicating money laundering.

Simulation

Classical computers have been used for decades in critical applications that model real-world processes or systems in order to study their behaviors over time. These computer-based simulations have had an enormous impact on fields like pharmaceuticals, material science, finance, logistics, aerospace, defense and computer-aided design and engineering. Simulations are essentially mathematical models of a system and hence are logical candidates to benefit from quantum computing. Many important systems, such as molecular structures, cannot be accurately modeled due to the level of complexity associated with representing the properties and behaviors of the key elemental components.

We believe that quantum computers possess inherent advantages that will allow them to accurately model systems with large numbers of variables that are far outside the reach of classical computers today.

Quantum Mechanical System Simulations

The essential building blocks of nature, whose understanding has been the driver of many breakthrough innovations in pharmaceuticals, healthcare, energy, and material science, are the microscopic systems of molecules, atoms and subatomic particles like electrons and protons. The properties and behaviors of these quantum mechanical systems can be expressed in mathematical rules that have been verified experimentally with high degrees of accuracy, but the complexity associated with such calculations, and their applicability to existing and potential molecular and atomic structures, has proven to be outside the realm of capability for today’s classical computers.

Scientists have not found a way to rapidly and accurately model most quantum mechanical systems on a computational device that itself is not quantum in nature. Conversely, we believe quantum computers have the potential to efficiently model the relevant set of potential interactions between quantum mechanical elements because they natively reflect the essential properties of quantum systems and behaviors like entanglement, superposition and wave functions.

Drug discovery is among the fields where research into the applicability of quantum computing for simulating quantum mechanical systems is producing considerable enthusiasm. With the growing high costs to develop new drugs, a quantum-based approach that could help pharmaceutical companies evaluate thousands of potential compounds for a targeted therapeutic, and avoid failed outcomes in costly clinical trials, would have an enormously positive economic and societal effect. Other high potential impact areas for quantum mechanical simulations include the design of chemical catalysts, computational fluid dynamics in aerospace engineering, and nuclear fusion for clean energy.

Introduction to Quantum Computing

Quantum computers encode and process data using a new kind of information storing electrical circuit called a quantum bit, or qubit. By leveraging the quantum mechanical principle of superposition, qubits can represent complex mathematical combinations of both zero and one at the same time. In contrast, classical computers are composed of transistors, electronic devices that hold binary zero or one states, therefore requiring billions of transistors in order to execute complex algorithms. This qubit property of superposition creates unique capabilities. By enabling qubits to encode more information than classical bits, it allows for a quantum computer’s power to scale exponentially, rather than linearly as with traditional computers based on transistors. Additionally, it makes it possible to construct algorithms that can evaluate all possible solutions to a problem simultaneously, rather than sequentially as is the case with classical computing. Furthermore, making qubits does not require expensive, continually shrinking lithography in order to improve performance, as transistor-based computers do. Qubits can be made using trailing edge semiconductor tools, so computer performance is decoupled from chip manufacturing cost.

These properties enable quantum computers to excel at solving problems with a large number of variables, highly complex and numerous solutions, or strong correlations or interactions. Many of these problems are currently intractable due to the scaling limits of classical computers and thus represent opportunities for computational advancement across many industries, including finance, pharma and biotechnology, energy, logistics, aerospace, defense and intelligence, and basic research and development.

How Quantum Computers Compute

To execute a quantum computation, classical data, which represents the problem to be solved and the algorithm, is translated into control sequences, or quantum logic gates, and applied to the qubits in the quantum computer. These sequences are called quantum circuits. Once the circuit has been executed on the quantum computer, the qubits are measured, resulting in classical data flowing out of the quantum computer and back into classical memory. The level of performance of a quantum computer in executing these circuits and solving computational problems is dictated by many factors. These include the scale, or number of qubits available in the quantum processor to encode the problem and algorithm, with more qubits enabling exponentially more complex and challenging problems to be represented; the fidelity of the quantum logic gates from which circuits are composed, which determines how often errors occur when the circuit is executed; the gate speed, which shapes the time taken to execute a given circuit; the co-processing technology and integration, which determines the rate at which classical data representing the problem and algorithm can be loaded into the quantum computer, and the rate at which it flows back out upon completion of the circuit execution; and re-programmability, or the speed with which the specific quantum circuit being executed may be updated to move on to the next step in a computational process.

Several candidate physical systems, or modalities, have been proposed or are being pursued, to form the basic physical qubits in quantum computers. These include, first and foremost, the superconducting qubit technology leveraged by us. They also include approaches based on trapped ions, trapped neutral atoms, and photonics. There is a varying degree of promise, potential and risk in building machines capable of meeting the above requirements for broad commercial utility. As outlined below, it is widely believed that superconducting qubit technology is the most mature, the most advanced, and most likely to ultimately lead to broad commercial success.

Requirements for Practical Workloads: Path to Quantum Advantage

Unlocking the broad commercial market for quantum computing calls for quantum computers that are able to solve practical commercial problems better, faster, or cheaper than the best alternative classical computing solution, including even the most powerful supercomputers. This inflection point is referred to as quantum advantage. Achieving quantum advantage imposes requirements on the quantum computer itself, the most important of which relate to the above performance factors of scale, fidelity, speed, co-processing, and re-programmability.

Scale. In order for quantum computers to solve problems out of reach for classical computers, such as modeling molecules with many electrons in order to enhance drug discovery, they require a significant number of high-performing qubits, likely starting at around 1,000 qubits.

Fidelity. A gate fidelity estimates the reliability of an operation. For instance, a two-qubit gate with a gate fidelity of 99% means that 99 out of 100 times the operation will provide the correct result. Errors can be caused by imperfect control, natural manufacturing variations, finite qubit lifetimes (coherence) or other sources. Overall, high fidelities of close to 99.9% are likely necessary to enable performance benefits on practical workloads. An error per operation is defined as (1-fidelity).

Speed. Speed is a crucial metric for all types of computers, both quantum and classical. Since quantum algorithms are ultimately composed of logic gates applied sequentially to qubits in a quantum computer, the speed with which these gates can be executed translates directly into processing speed and workload throughput. Therefore, faster quantum processing speeds can result in a larger number of addressable problems and larger market opportunity, as well as a more direct path to outperforming classical alternatives and a higher intrinsic revenue potential.

Co-processing. Hybrid architectures that leverage quantum computers as co-processors, pioneered by us since the company’s inception, have now become widely adopted in the quantum computing industry. Quantum co-processing delivered over the cloud, such as our QCS platform, is the predominant framework for building and using quantum computers today. In this paradigm, quantum processors are tightly integrated with classical computing systems and infrastructure to ensure the rate of data flowing in and out of the quantum processor can meet the needs of commercial applications. Effective implementation of co-processing hinges on both the intrinsic technological features of the specific qubit technology, as well as product innovations and system architectures aimed to prioritize this capability. For example, just as in classical computing architecture, fast gate speeds, coupled with a network architecture that achieves low network latency for data flow, are some of the requirements for high performance co-processing.

Reprogrammability. Reprogrammable quantum computers are general purpose machines that should be able to run any quantum algorithm, provided the machine has the scale, fidelity, and other attributes needed to support the particular problem instance. While gate-model quantum computers, such as those made by us, IBM, IonQ and Google, are typically reprogrammable, different technology approaches and architecture choices lead to varying constraints in applying this capability in a practical setting. Specifically, the ability to dynamically reprogram the quantum processor during the execution of a quantum circuit or within the coherence time of its qubits is of particular importance for many anticipated applications and use cases.

While research and development funding and investments into quantum computing have accelerated, we believe that long-term commercial demand for quantum computing systems hinges on the ability to meet the above criteria for running practical workloads. Multiple quantum hardware modalities are being pursued. Among these, we believe the superconducting qubit is the only such modality that has, to date, demonstrated viability across all these requisite metrics.

Our Superconducting Quantum Processors

Introduction to Superconducting Qubits

We build and operate quantum computers based on superconducting qubits. Superconducting qubits are silicon-based electronic devices that encode information in quantum states associated with currents and voltages. Superconducting qubits benefit from the fact that their basic properties can be engineered through well-established semiconductor industry design and manufacturing techniques. This enables chip design and architecture tradeoffs to be made to overcome various practical constraints in building commercial quantum computing systems. They are also improving along these key metrics faster than approaches based on other qubit modalities, such as ion traps, photonics and neutral atoms.

As an example, in June 2011, the largest algorithms demonstrated on programmable, gate model quantum computers across these modalities were in the range of a few qubits. In the ensuing period from 2012 to 2025, superconducting systems have successfully scaled up to over 100 qubits, including demonstrations of quantum supremacy. This rate of scaling has easily outpaced other approaches. We believe this leadership results in part from an intrinsic advantage: superconducting qubits have many inherent similarities to traditional silicon-based chips. As a result, progress in superconducting quantum computers may be achieved by leveraging the existing capabilities – expertise, technologies, workforces, and supply chains, for example – of the semiconductor manufacturing industry, rather than needing to establish such capabilities anew.

Rigetti Quantum Processors

Rigetti quantum processors are based on transmon-style superconducting qubits. Quantum logic gates are actuated by applying electronic signals to the qubits. Chips are packaged, connected to input and output circuitry, and operated in a low-temperature environment. Control and readout signals are generated and processed in a control system operating at room temperature. This control system is subsequently integrated with, or networked into, auxiliary classical computing hardware to enable co-processing system requirements. Our competitive advantage begins at the chip level and extends through the full-stack, with a distinct focus on fabricating scalable hardware meeting the requirements for practical workloads.

Scale

Achieving the scale of quantum processor needed for practical workloads is perhaps the hardest requirement of all. To address this, we have developed a unique patented and patent-pending multi-chip quantum processor technology. This approach leverages techniques long used in classical computer microprocessors and memory (“RAM”). Our scalable processor architecture enables multiple core processor chips, each having many qubits, within a multi-chip assembly to function cohesively as a single, large quantum computer-without introducing additional error sources, network latency or other overhead. Using our modular chip architecture, larger quantum processors may be constructed by assembling more core processors together. From a manufacturing perspective, this enables a single type of core processor chip to support multiple quantum processor generations of increasing scale and performance. We believe that this solution facilitates rapid scaling and can enable even faster development cycles in future chip generations.

In addition to accelerating the pace of scaling, we believe our proprietary modular chip architecture has significant manufacturability and cost benefits. For example, rather than producing large, complex individual chips with 1,000 qubits, we may fabricate 10 chips with 100 qubits each and use our multi-chip technology to assemble them together to produce a 1,000 qubit quantum processor. This solution makes it much easier to produce large processor chips with high yield. As a result, we believe our modular approach to be fundamentally more manufacturable, predictable, and scalable.

Our multi-chip technology incorporates several advances in integrated circuit design, architecture, and silicon device manufacturing. These advances include superconducting multi-chip bonding technology for chip-level 3D integration, superconducting through-silicon via process technology and interchip coupling technology that enables high-fidelity two-qubit logic gates between qubits disposed on different silicon dies. These innovations have resulted from our investment in more than five years of technological development to establishing the essential capabilities to produce quantum processors meeting the requirements for broad commercial utility. We believe our approach to scaling quantum computers will accelerate us toward quantum advantage systems.

Fab-1

We have developed, own and operate the distinctive manufacturing capabilities needed to produce quantum processors in our proprietary scalable architecture. In 2017, we became the first company to build a dedicated and integrated Fab for producing quantum processors. In addition to vertically integrating the process capabilities to produce our proprietary chips, Fab-1 delivers a high mix of development chips to internal teams. This in-house fabrication capability allows for rapid design-fab-test cycles of learning, enabling an innovation cycle we estimate to be two to five times faster than a typical MEMS or semiconductor foundry. In Fab-1, our engineers focus their efforts on rapidly exploring, then optimizing new chip designs and establishing repeatable manufacturing processes. Fab-1 also includes semi-automated chip testing and characterization capabilities. Additionally, by leveraging traditional semiconductor tools and processes, Fab-1 builds on expertise from the existing semiconductor industry, a distinct advantage over other qubit modalities.

This in-house fab capability has enabled us to accumulate the hands-on experience and intellectual property, including know-how, patents, and trade secrets, to produce quantum computer chips within our scalable, proprietary architecture. Furthermore, we believe Fab-1 has enough wafer capacity to supply all of our chip needs for at least the next three years.

Cooling

Like all high-performance computing systems, Rigetti quantum computers require an advanced cooling system. In this case, commercially available dilution refrigerators maintain chip temperatures at around 0.02 Kelvin. Cooling power requirements and associated electricity costs will scale approximately linearly with qubit count, while expected computational utility increases exponentially.

As a result, we expect the electricity costs to run the cooling systems of our quantum computers to make up an ever-decreasing fraction of the overall revenue generated from each machine. In addition, we work closely with refrigerator vendors and anticipate the commercial availability of dilution refrigerator systems with the capabilities to support our product roadmap.

Fidelity

Improvements to the coherence times of superconducting qubits, combined with methods for ever faster and more precise quantum logic gates, have kept superconducting qubits on a pace of continuous fidelity improvement for approximately two decades. In recent years, algorithms have been developed on processors with average two-qubit gate fidelities of 98-99.5%. As processors scale to broad quantum advantage, fidelity will need to continue to improve, likely to 99.9% and beyond.

We are focused on delivering advances to fidelity through a systematic engineering approach centered on our design-fab-test flywheel powered by our in-house design and manufacturing. Uniquely, our modular processor technology enables improvements to fidelity to be achieved separately from efforts to increase scale; fidelity advancements can be developed on the individual core processor chips, and these improvements can be rapidly integrated into scaled processors through our multi-chip integration technology.

As described above, a quantum logic gate is how computation is expressed on a quantum computer. There are a large number of possible gates that can be used for computation. We physically implement quantum gates through the application of microwave pulses (electronic signals) to the physical qubits on the quantum integrated circuit.

One way that the performance of the system is assessed is by measuring the errors that are introduced in actuating the gates with the application of electronic signals to the physical qubits. There are a variety of metrics that are used to measure these errors; we currently report performance and indicate a measure of error through a fidelity metric applied to two-qubit gate error or fidelity, usually expressed as a percentage. Gate fidelity represents the reliability of an operation. For example, a two-qubit gate with a fidelity of 99% means that 99 out of 100 times the measurement of the gate will produce the correct result. Fidelities are related to errors in the following way: 100% - error rate % = gate fidelity %. So, an error rate of .5%, is the same as a fidelity of 99.5%. There are a number of standard benchmarks that are used to measure qubit errors and are explained further below.

We measure the performance of iSWAP and CZ gates with an industry standard technique called Randomized Benchmarking, a commonly used method to measure fidelity. This protocol requires creating random sequences of quantum gates of different sequence length, executing each sequence, and then measuring the outcome of the execution against the mathematically expected results.

On iSWAP-enabled devices, such as Ankaa-3, we also implement a family of two-qubit gates referred to as fSim. Generally, any specific fSim gate may not be part of a universal gate set. We use fSIM gates with the goal of achieving high performance for specific algorithms.

We measure the performance of fSim gates with an industry standard technique called cross entropy benchmarking, another commonly used method to measure fidelity. This protocol requires creating random circuits from the provided gate set measuring the results and comparing the outcomes to an expected probability distribution of outcomes.

In the past we have implemented gate sets based on two-qubit gates other than CZ, iSWAP and fSIM, and may, in the future, choose different gate sets. At the moment there is no standard set of gates agreed on in the industry, and there may never be. Furthermore, other standards for measurement may emerge to measure quantum gate fidelity or performance of quantum computers generally. Accordingly, undue reliance should not be placed on the fidelity measures that we present. See also “Risk Factors— We face significant technical and engineering challenges in completing the development of our quantum computers, producing our quantum computers at scale, achieving our targeted performance milestones, and realizing quantum advantage or LFTQC, any of which if not accomplished would adversely impact our business, financial condition, and results of operations.”

Cepheus-1-36Q is our newest flagship quantum computer featuring our proprietary modular chip architecture, optimized two-qubit gates and advances in intermodule coupler design that is intended to enable superior performance. With Cepheus-1-36Q, we successfully halved our error rates from our previous Ankaa-3 system, achieving a median two-qubit fidelity of 99.6% (based on internal testing) as of January 2026. We believe Cepheus-1-36Q is the first multi-chip quantum computer in the industry to achieve this level of performance based on publicly available information. Improving our median two-qubit fidelities is a crucial part of our mission to build the world’s most powerful computers. Useful quantum computers will need not only a large number of qubits, but also high-quality qubits. Reaching 99.6% median two-qubit fidelity on the Cepheus-1-36Q system is the result of years of innovation and commitment from our teams across the technology stack.

We believe that Cepheus-1-36Q validates our modular architecture approach to scaling. Tiling multiple chips together demonstrates what we believe is the way forward towards building larger systems. We believe a densely connected square lattice with tunable couplers that allows us to control qubit interactions is the foundation for driving qubit performance. We believe a 2.0x improvement in error performance compared to our previous QPUs, coupled with our scaling approach, shows that we have a promising strategy for building increasingly higher performing QPUs to help our customers solve their most pressing problems.

Speed

One of the strengths of superconducting qubit technology, and our technology in particular, is that gate operations on superconducting processors are faster than other commercially available modalities today.

The speed of gate operations in superconducting qubits are determined by the intentional design of circuit elements on-chip and their optimized parameters, rather than relying on atomic properties. Our recently introduced Cepheus-1-36 system achieves a median gate time of 76 nanoseconds with universal CZ gates. Median gate time is measured by internal testing.

We believe that superconducting processors’ speed advantage will result in a larger market for superconducting quantum computers compared to other modalities, as there are a multitude of high value use cases that require timely results, such as real-time decision making, risk calculations, and more. As in conventional computing, faster gate speeds also equate to higher throughput in commercial deployment and therefore greater potential revenue opportunity.

Co-processing

It is widely believed that unlocking the commercial value of quantum computing requires quantum computers to be tightly integrated with classical computing systems and technology. High-performance co-processing integration accelerates the path to quantum advantage by enabling both quantum and classical computing resources to work in tandem to address computational bottlenecks best suited to their particular strengths. This approach also facilitates adoption and usability by end users who are more familiar with classical programming.

The inherent speed with which superconducting processors can execute circuits and be dynamically re-programmed makes them ideally suited to high-speed co-processing integration. Other modalities have not demonstrated the gate speeds necessary to support high-performance co-processing.

We have invented and patented capabilities at the hardware and software level, such as parametric code compilation, to enable high performance co-processing on a cloud platform. Parametric code compilation supports running faster hybrid algorithms through memory registers shared between classical programs and embedded logic on a QPU control system. This means that users can run algorithms without incurring latency that would otherwise be caused by updating parameters at each step.

Reprogrammability

Our systems are dynamically reprogrammable. Instructions are streamed into the quantum computer or updated within the execution time of the quantum logic circuit. This allows our machines to effectively run both the hybrid variational algorithms that underpin current use cases and quantum error correction routines in future systems. In a production setting, dynamic reprogrammability translates to higher customer job throughput per unit time. Since many applications are expected to require streamed data processing or error correction, we believe this dynamic reprogrammability is central to unlocking the full market potential of quantum computing systems, especially in comparison to alternative modalities that are unable to implement high speed re-programming.

Our quantum computers are orchestrated with a control system operated at room temperature. In our architecture, reprogramming the quantum processor occurs exclusively within this control system. Unlike photonics, for example, reprogramming the system to run a new quantum circuit does not require slow on-chip updates, but only requires changes to the sequence of signals applied to the chip.

Our QPUs today support dynamic programming protocols within microsecond feedback loops. For example, re-setting registers of qubits conditional on the outcomes of previous measurements, can increase overall quantum circuit throughput by 5x relative to non-dynamic implementations of the same workload.

The QPU control system includes hardware for networking, classical microprocessors, field-programmable gate arrays (FPGAs) for control and readout pulse sequencing, and analog signal processing. The integrated system is designed and built to meet the requirements for co-processing and reprogrammability over the cloud.

This capability enables high-speed data flow within the quantum processor, and between the quantum processor and auxiliary classical compute and networking infrastructure. Our systems are thus enabled for high-performance hybrid quantum-classical computing, the implementation of high-throughput quantum programs for practical workloads, and the dynamic control flow and feedback that underpins practical quantum error correction. The control system drives the quantum processor, calibrates and operates gates, and measures qubit states at the end of a computation.

Quantum Error Correction

Direct improvements to qubits and gate fidelities are currently the primary means of advancing the performance of quantum computers. However, at the scale of a few hundred qubits and beyond, a method called quantum error correction can be applied to further accelerate this rate of progress.

In quantum error correction, a large number of individual physical qubits can be transformed, through repeated application of gate and readout operations designed to detect and fix physical errors, into single “logical” qubits, whose properties are exponentially improved relative to the constituent physical qubits. While the methodology of quantum error correction is well-established in the field of quantum computing, systems capable of running such codes at a commercially useful scale are not currently available. Eventually, solving certain classes of problems will require the ability to compute with tens to hundreds or even thousands of logical qubits. This makes the ability to build large qubit count processors at this commercial scale an even more crucial capability.

Additionally, because errors must be identified at a specific physical location within the quantum processor in order to be corrected, those errors must also be well-localized within small regions of the quantum processor. For example, a qubit in one region must not induce errors on some distant qubit but rather be constrained to influencing errors on nearby qubits. This essential requirement underpins modern quantum error correction theory and practice.

Turning to the processor’s physical qubit array, the necessity of localizing errors has led to the predominance of nearest-neighbor connectivity graphs in quantum processor design. Our quantum processors meet these essential requirements with a nearest-neighbor, planar connectivity graph. Planar codes are expected to show a high error threshold of approximately 1% error probability per operation. This means that if error rates are below the required threshold (e.g., 1%), then increasing the redundancy (i.e., the number of physical qubits making up a single logical qubit) results in an exponential reduction in logical error. In other words, adding a small number of additional physical qubits per logical qubit will provide exponential improvements. Notably, codes for other modalities, such as Bacon-Shor codes for trapped ion qubits, lack such a threshold behavior and is one reason why we believe superconducting quantum computers to be superior to trapped ion modalities.

We aim to deliver the physical qubit count needed, with the requisite nearest-neighbor connectivity, to enable developers and customers to benefit from this exponential error reduction. In contrast to known approaches for other qubit modalities, our systems are expected to be able to run the same code family at multiple different levels of redundancy without requiring additional complexity such as code concatenation. This approach enables developers to scale the effective error rate and associated overheads up and down as dictated by their use-case requirements. For example, the smallest surface code logical qubit for superconducting processors is 17:1 physical qubits to logical qubits, in comparison to 16:1 for trapped ions. However, for complex applications, the ability to pack more physical qubits into the code (such as 100:1 or 1000:1) is critical because it allows developers to further reduce errors for algorithms based on many quantum gates where errors are more likely to accumulate. In comparison to trapped ions, we believe superconducting processors are better positioned to scale up to the large number of qubits required to run these valuable large codes while also having the fast gate speeds for them to be useful.

Our processor architecture, software tools, and cloud services platform are designed to enable users and partners to directly construct, test and deploy error correction and error mitigation protocols, and to tailor such codes to specific computational tasks through software. This capability is enabled by the re-programmability, co-processing integration, and system design we have established.

Intellectual Property

Our intellectual property portfolio plays a strategic role in advancing our innovation and leadership in quantum computing.

Our patent portfolio seeks to protect our current developments and the intellectual property space for the company’s technology roadmap and anticipated areas of development. We rely upon a combination of protections afforded to owners of patents, copyrights, trade secrets, and trademarks, along with confidentiality and proprietary rights agreements with employees, consultants, contractors, vendors, and business partners to establish and protect our intellectual property rights.

As of December 31, 2025, we have 121 patents issued and 160 patents pending that are designed to protect our full-stack technology across hardware, software, and services. These patents cover a broad range of key technology areas of the business including: (i) quantum computing systems, software, and access; (ii) quantum processor hardware; (iii) algorithms and applications for problem solving; and (iv) chip design & fabrication.

We pursue international registration of our domain names and trademarks. We are the registered holder of a variety of domain name registrations, including “rigetti.com.” Our trademark registrations include “Rigetti” in the US, U.K. and EU.

Sales & Marketing

During this period of emerging quantum advantage, our go-to-market strategy is focused on being a leader in the key market segments driving the early application of quantum computing. Our sales and marketing efforts are focused on technology development and distribution partnerships with the leading organizations in these markets. In the U.S. government, for example, the Departments of Defense and Energy have each been making significant investments in quantum computing. We have technology development partnerships with leading government agencies and national laboratories.

We are pursuing similar arrangements with customers in other important vertical market segments, like finance, where we are developing specific expertise in several application areas and are collaborating with Moody’s, HSBC and Standard Chartered Bank. We also have distribution relationships with customers like Amazon Web Services, Microsoft Azure and Strangeworks.

As we work to develop new generations of our hardware with the goal of continuing to scale and achieve QA, we anticipate increasing our investment and expenses in both sales and marketing in the future to expand the number of enterprise companies buying our QPUs and directly licensing our QCS platform.

Suppliers

We source our components from multiple industries including from the electronics and semi-conductor industries with low-noise microwave components, CPUs, GPUs, FPGAs; from the cryogenic industry with dilution refrigerators and associated helium gas products; and from the semiconductor industry with silicon wafers and other specialty materials, tooling and measurement equipment.

Customers & Key Partners

We believe that the realization of quantum computing’s promise requires strong relationships across an ecosystem of innovative and quantum-committed organizations and have been developing commercial relationships and collaborative partnerships with organizations that possess a keen understanding of specific industry problems and deep technical expertise in key scientific and engineering disciplines.

To date, we have focused on developing a range of client relationships and research partnerships with:

Enterprise-sized organizations working on quantum-assisted breakthroughs in applications areas like drug discovery, network optimization, financial modeling, weather forecasting and fusion energy like NASA, Moody’s, Standard Chartered Bank, HSBC, AFRL, the U.S. DOE and certain military branches within the U.S. Department of Defense;
Materials science researchers and quantum algorithm developers at renowned laboratories like Fermilab, NASA Quantum Artificial Intelligence Laboratory and ORNL;
Quantum-focused software and algorithm companies like Phasecraft, Riverlane and Q-CTRL;
Cloud service providers like Amazon Web Services and Microsoft Azure; and
We also enter into multi-year technology development partnerships with organizations that possess specialized technical expertise and strong interests in advancing the development of quantum computing (as referenced in Business - Key Technology Development Partnerships). These organizations include DARPA, SQMS, Innovate UK and Quanta.

Competition

The quantum computing market is evolving and highly competitive. With the introduction of new innovations and the potential entry of new competitors into the market, we expect competition to increase in the future, which could harm our business, results of operations, or financial condition.

Our current and prospective competitors include companies engaged in the research, development, and operation of quantum computing capabilities. Major companies now developing both quantum hardware and software include IBM, Google, Microsoft, IonQ, D-Wave, Quantinuum and PsiQuantum, among others. In addition, because of the importance of quantum computing, most large public cloud providers and traditional chip makers are researching and investing in quantum computing initiatives, in some cases seeking to build quantum computers. For example, Amazon is engaged in the research and development of quantum computers. A number of development-stage companies are also seeking to build quantum computers, quantum software and applications, and quantum cloud computing services.

We believe our primary direct competition will come from other companies building or seeking to build universal, gate-model quantum computing systems that can meet the requirements for solving commercial problems. We believe competition will be based on a number of factors, including: different approaches to building quantum computers; quantum computer system performance, including scale, speed, and fidelity; system accessibility and ease of use; supported software and applications; compatibility with existing classical workflows; rate of technological innovation; ability to create value through long-term partnerships; end-user support and customer experience; solutions and insight delivery; price; brand recognition and trust; financial resources; and access to key personnel.

We believe that we are favorably positioned to compete on the basis of these factors. However, we face various risks relating to competition as described in “Risk Factors-Risks Related to Our Business and Industry-The quantum computing industry is in its early stages and volatile and is competitive on a global scale and we may not be successful in competing in this industry or establishing and maintaining confidence in our long-term business prospects among current and future partners and customers.”

ITEM 1A. Risk Factors

RISK FACTORS

Investing in our securities involves a high degree of risk. Before you make a decision to buy our securities, in addition to the risk and uncertainties described above under “Cautionary Note Regarding Forward-Looking Statements”, you should carefully consider the risks and uncertainties described below together with all of the other information contained in this Annual Report on Form 10-K. If any of the events or developments described below were to occur, our business, prospects, operating results and financial condition could suffer materially, the trading price of our securities could decline, and you could lose all or part of your investment. The risks and uncertainties described below are not the only ones we face. Additional risks and uncertainties not presently known to us or that we currently believe to be immaterial may also adversely affect our business.

Risks Related to Our Financial Condition and Status as an Early-Stage Company

We are in our early stages and have a limited operating history, which makes it difficult to forecast the future results of our operations. We have in the past failed to meet publicly announced milestones and may fail to meet projected technological milestones in the future. In addition, we have in the past changed our technology roadmap, including the anticipated milestones and timing thereof.

Our business was founded in 2013 and has operated quantum computers over the cloud since 2017. As a result of our limited operating history, our ability to accurately forecast the future results of operations is limited and subject to a number of uncertainties, including our ability to plan for and model future growth. Our ability to generate revenues will largely be dependent on our ability to develop and produce quantum computers with increasing numbers of quantum bits (“qubits”) and with increasing levels of performance. As of the date hereof, we have deployed a quantum computer having 84 qubits with a 99.0% two-qubit gate fidelity (based on internal testing) and 36-qubit quantum computer with a 99.6% two-qubit median gate fidelity (based on internal testing) which utilizes our modular chip architecture. We are still in the technology development phase. Our scalable business model has not been formed as of yet and our technology roadmap may not be realized as quickly as hoped, or even at all. We have in the past failed to meet publicly announced milestones and may fail to meet projected technological milestones in the future. We have in the past changed our technology roadmap, including the anticipated milestones and timing thereof, including in each of the years ended December 31, 2018, 2022, 2023 and 2025. We may further update our technology roadmap in the future, including anticipated milestones and anticipated timeline for milestones. Furthermore, we may be unable to achieve the milestones in our technology roadmap on their announced anticipated timeline or at all, including our next generation of modular system architecture, targeted qubit counts and fidelities. The development of our scalable business model will likely require the incurrence of a substantially higher level of costs than incurred to date, while our revenues will not substantially increase unless and until more powerful, scalable, higher performing computers are produced, which requires a number of technological advancements which may not occur on the currently anticipated timetable or at all. As a result, our historical results should not be considered indicative of our future performance. Further, in future periods, our growth could slow or decline for a number of reasons, including but not limited to slowing demand for sales of our on-premise quantum computers, QCaaS or QCS, increased competition, changes to technology, inability to scale up or improve performance of our technology, a decrease in the growth of the market, or our failure, for any reason, to continue to take advantage of growth opportunities.

We have also encountered, and will continue to encounter, risks and uncertainties frequently experienced by growing companies in rapidly changing industries. If our assumptions regarding these risks and uncertainties and our future growth are incorrect or change, or if we do not address these risks successfully, our operating and financial results could differ materially from our expectations, and our business could suffer. Our success as a business ultimately relies upon fundamental research and development breakthroughs in the coming years. There is no certainty these research and development milestones will be achieved as quickly as hoped, or even at all.

We have a history of operating losses and expect to incur significant expenses and continuing losses for the foreseeable future.

We incurred net losses of $216.2 million and $201.0 million for the years ended December 31, 2025, and 2024, respectively. As of December 31, 2025, we had an accumulated deficit of $771.0 million. We believe that we will continue to incur operating and net losses each quarter until at least the time we begin generating significant revenue if we are able to achieve quantum advantage or LFTQC, which may never occur. Even if our quantum computers were to achieve quantum advantage or LFTQC, we may never become profitable.

We may incur significantly higher losses in future periods as we, among other things: continue to incur significant expenses in connection with the design, development and manufacturing of our quantum computers; expand our research and development activities; invest in manufacturing capabilities; build up inventories of components for our quantum computers; increase our sales and marketing activities; develop our infrastructure; and increase our general and administrative functions to support our growing operations and our being a public company.

We may find that these efforts are more expensive than we currently anticipate or that these efforts may not result in revenues, which would further increase our losses. If we are unable to achieve and/or sustain profitability, or if we are unable to achieve the growth that we expect from these investments, it could have a material adverse effect on our business, financial condition or results of operations. Our business model is unproven and may never allow us to cover our costs.

We will require a significant amount of cash for expenditures as we invest in ongoing research and development and business operations and may need additional capital sooner than planned to pursue our business objectives and respond to business opportunities, challenges or unforeseen circumstances, and we cannot be sure that additional financing will be available. If we are unable to raise additional funding when needed, we may be required to delay, limit or substantially reduce our quantum computing development efforts.

Our business and future plans for expansion are capital-intensive, and the specific timing of cash inflows and outflows may fluctuate substantially from period to period. We will require a significant amount of cash for expenditures as we invest in ongoing research and development and business operations. For example, in addition to our continuing investment in our technology roadmap we may seek to significantly increase our capital expenditures, including to upgrade our current Fab-1 chip fabrication facility, and possibly invest in a new quantum chip fabrication facility, which would require a significant amount of cash for capital expenditures and increase our depreciation expense in future years. The actual amounts we may be required to spend on these, and other matters may be greater and more significant than our expectations. Further, pursuant to the Collaboration Agreement with Quanta, we agreed to invest at least $250 million in the field of quantum computing, in furtherance of our technology roadmap, over a five-year period commencing in February 2025.

We believe that our existing balances of cash, cash equivalents and available-for-sale investments will be sufficient to meet our anticipated operating cash needs for at least the next twelve months based on our current business plan, and expectations and assumptions considering current macroeconomic conditions. Our operating plan may change because of factors currently unknown, and we may need to seek additional funds sooner than planned, through public or private equity or debt financings or other sources, such as strategic collaborations or other transactions. For example, in the future, we may seek to significantly increase our capital expenditures, including to upgrade our chip fabrication facility, possibly invest in a new quantum chip fabrication facility and for additional quantum computing refrigerators, which would require a significant amount of cash for capital expenditures.

In addition, we may seek additional capital even if we believe that we have sufficient funds for current or future operating plans. Such financings may result in dilution to stockholders, issuance of securities with priority as to liquidation and dividend and other rights more favorable than Common Stock, imposition of debt covenants and repayment obligations or other restrictions that may adversely affect our business. Any funds we raise may not be sufficient to enable us to continue to implement our long-term business strategy. Further, our ability to raise additional capital may be adversely impacted by worsening global economic conditions and disruptions to and volatility in the credit and financial markets in the United States and current and future military conflicts and wars around the world including related sanctions and tariffs and trade protection measures. There can be no assurance that deterioration in credit and financial markets and confidence in economic conditions will not occur. A severe or prolonged economic downturn could result in a variety of risks to our business, including weakened demand for our products and services and our ability to raise additional capital when needed on acceptable terms, if at all. If the equity and credit markets deteriorate, it may make any necessary financing more difficult, more costly, and more dilutive. Failure to secure any necessary financing in a timely manner and on favorable terms could impair our ability to achieve our growth strategy, could harm our financial performance and stock price, could require us to delay or abandon our business plans, and could require us to delay, limit, or substantially reduce our quantum computing development efforts.

If we are unable to obtain sufficient capital we would be unable to fund our operations and may be required to evaluate alternatives, which could include dissolving and liquidating our assets in which case we may receive less than the value at which those assets are carried on our audited financial statements, and/or seeking protection under bankruptcy laws, and a determination to file for bankruptcy could occur at a time that is earlier than when we would otherwise exhaust our cash resources, and it is unclear to what extent we would be able to pay our obligations, and, accordingly, it is further unclear whether and to what extent any resources would be available for distribution to stockholders. This could potentially cause us to cease operations and result in a complete or partial loss of your investment in our securities. We cannot anticipate all the ways in which the economic climate and financial market and geopolitical conditions could adversely impact our business.

There can be no assurance that financing will be available to us on favorable terms, or at all. In addition, our ability to raise additional capital through the sale of securities could be significantly impacted by the resale of our securities by holders of our securities which could result in a significant decline in the trading price of our securities and potentially hinder our ability to raise capital at terms that are acceptable to us or at all.

We may not be able to scale our business quickly enough to meet customer and market demand, which could result in lower profitability or cause us to fail to execute on our business strategies.

In order to grow our business, we will need to continually evolve and scale our business and operations to meet customer and market demand. Quantum computing technology has never been sold at large-scale commercial levels. Evolving and scaling our business and operations places increased demands on our management as well as our financial and operational resources to:

attract new customers and grow our customer base;
maintain and increase the rates at which existing customers use our platform, sell additional products and services to our existing customers, and reduce customer churn;
invest in our platform and product offerings;
effectively manage organizational change;
accelerate and/or refocus research and development activities;
expand manufacturing and supply chain capacity;
increase sales and marketing efforts;
broaden customer support and services capabilities;
maintain or increase operational efficiencies;
implement appropriate operational and financial systems; and
establish and maintain effective financial disclosure controls and procedures.

Commercial traction of quantum computing technology may never occur. We may not be able to cost effectively manage production at a scale or quality consistent with customer demand in a timely or cost-effective manner.

Our ability to scale is dependent also upon components we must source from multiple industries including: the electronics and semi-conductor industries with low-noise microwave components, CPUs, GPUs, FPGAs; the cryogenic industry with dilution refrigerators and associated helium gas products; and the semiconductor industry with silicon wafers and other specialty materials, tooling and measurement equipment. Shortages or supply interruptions in any of these components will have an adverse impact on our business.

If large-scale development of our quantum computers commences, our computers may contain defects in design and manufacture that may cause them to not perform as expected or that may require repair and design changes. Our quantum computers are inherently complex and incorporate technology and components that have not been used for other applications and that may contain defects and errors, particularly when first introduced. We have a limited frame of reference from which to evaluate the long-term performance of our computers. There can be no assurance that we will be able to detect and fix any defects in our quantum computers in a timely manner that does not disrupt our sales of products and services to our customers.

If our technology fails to perform as expected, customers may seek out a competitor or turn away from quantum computing entirely, each of which could adversely affect our sales and brand and could adversely affect our business, prospects and results of operations. If defects in our technology lead to erroneous outputs, third parties relying on those outputs may draw from them erroneous conclusions, creating a risk that we will be liable to those third parties.

Even if the market in which we compete achieves its anticipated growth levels, our business could fail to grow at similar rates, if at all.

Our growth is dependent upon our ability to successfully market and sell quantum computers and quantum computing services and solutions, expand our solutions and services, retain customers, bring in new customers and retain critical talent. We do not have experience with the large-scale production and sale of quantum computing technology. Our growth and long-term success will depend upon the development of our sales and retention capabilities. Unforeseen issues associated with scaling up and constructing quantum computing technology at commercially viable levels could have a negative impact on our business, financial condition and results of operations.

Moreover, because of our unique technology, our customers will require particular support and service functions, some of which are not currently available, and may never be available. If we experience delays in adding such support capacity or servicing our customers efficiently or experience unforeseen issues with the reliability of our technology, we could overburden our servicing and support capabilities. Similarly, increasing the number of our products and services would require us to rapidly increase the availability of these services. Failure to adequately support and service our customers may inhibit our growth and ability to expand.

There is no assurance that we will be able to ramp our business to meet our sales, manufacturing, installation, servicing and quantum computing targets globally, that expected growth levels will prove accurate or that the pace of growth or coverage of our customer infrastructure network will meet customer expectations. For example, our competitors may achieve certain narrow and/or broad quantum milestones faster than us, which may negatively impact our business and prospects. Failure to grow at rates similar to that of the quantum computing industry may adversely affect our operating results and ability to effectively compete within the industry.

We may not manage growth effectively, including with respect to our employee base and managing our operations successfully.

Our failure to manage growth effectively could harm our business, results of operations and financial condition. We anticipate that a period of significant expansion will be required to address potential growth. This expansion will place a significant strain on our management, operational and financial resources. For example, expansion of and upgrades to our Fab-1 facility is continual and ongoing, and we may not complete the expansion and upgrades on terms originally anticipated, in a timely manner or at all, or we may decide to construct a new fabrication facility, both of which could have a material impact on our business, financial condition or results of operations. Expansion and upgrades or construction of a new fabrication facility requires significant cash investments and management resources and there is no guarantee that they will generate additional sales of our products or services, or that we will be able to avoid cost overruns or be able to hire additional personnel to support us. In addition, we also need to ensure our compliance with regulatory requirements in various jurisdictions applicable to the sale, installation and servicing of our products.

To manage the growth of our operations and personnel, we must establish and maintain appropriate and scalable operational and financial systems and procedures and controls, and establish and maintain a qualified finance, administrative and operations staff. We may be unable to acquire the necessary capabilities and personnel required to manage growth or to identify, manage and exploit potential strategic relationships and market opportunities.

Our ability to use net operating loss carryforwards and other tax attributes may be limited.

We have incurred losses during our history, do not expect to become profitable in the near future and may never achieve profitability. To the extent that we continue to generate taxable losses, unused losses will carry forward to offset future taxable income, if any, until such unused losses expire, if at all. As of December 31, 2025, we had U.S. federal net operating loss carryforwards of approximately $455.3 million.

Under current law, U.S. federal net operating loss carryforwards generated in taxable periods beginning after December 31, 2017, may be carried forward indefinitely, but the deductibility of such net operating loss carryforwards is limited to 80% of taxable income. It is uncertain if and to what extent various states will conform to current federal law.

In addition, under Sections 382 and 383 of the Internal Revenue Code of 1986, as amended (the “Code”), our federal net operating loss carryforwards, federal research and development tax credit carryforwards and other tax attributes are subject to annual limitations because of prior cumulative changes in our ownership and may be further limited in the future if additional ownership changes occur. An “ownership change” pursuant to Section 382 of the Code generally occurs if one or more stockholders or groups of stockholders who own at least 5% of a company’s stock increase their ownership by more than 50 percentage points over their lowest ownership percentage within a rolling three-year period. Similar rules apply under state tax laws. Our ability to utilize our federal net operating loss carryforwards, federal research and development tax credit carryforwards and other tax attributes to offset future taxable income or tax liabilities is limited because of prior ownership changes and may be further limited in the future if additional ownership changes occur. See Note 16 to our consolidated financial statements included elsewhere in this Annual Report on Form 10-K for information regarding our federal net operating loss carryforwards, federal research and development tax credit carryforwards and other tax attributes.

If we earn taxable income, such limitations will most likely result in increased future income tax liability and have an adverse effect on our future cash flows. We have recorded a valuation allowance related to our net operating loss carryforwards and other deferred tax assets due to the uncertainty of the ultimate realization of the future benefits of those assets.

Risks Related to Our Business and Industry

We face significant technical and engineering challenges in completing the development of our quantum computers, producing our quantum computers at scale, achieving our targeted performance milestones, and realizing quantum advantage or LFTQC, any of which if not accomplished would adversely impact our business, financial condition, and results of operations.

Producing quantum computers is a difficult undertaking, and there are significant engineering challenges that we must overcome to build our quantum computers. Some of the development challenges that could prevent the introduction of our quantum computers include, but are not limited to, failure to find scalable ways to manipulate qubits, failure to reduce error rates, failure to transition quantum systems to leverage low-cost components, and failure to realize multi-chip quantum computer technology.

Our successful execution of our technology roadmap is based on the development of multiple generations of quantum computing systems and the achievement of our targeted qubit counts and fidelities, including hardware that demonstrates quantum advantage and LFTQC, each of which is an important anticipated milestone for our technology roadmap and commercialization. The future success of our technology roadmap will depend upon our ability to continue to increase the number of qubits and decrease error rates in subsequent generations of our quantum computers.

Quantum advantage is the point at which quantum computers can solve a practical problem that would be physically impossible to solve on a classical computer. LFTQC is when quantum computing systems are available with hundreds of logical qubits, which can be universally controlled and measured with substantially error-free operation through the full course of a quantum computation. No current quantum computers, including our quantum hardware, have reached quantum advantage or LFTQC, and may never reach QA or LFTQC. Achieving QA or LFTQC will be critical to the success of any quantum computing company, including ours. However, achieving QA would not necessarily lead to commercial viability of the technology that accomplished such advantage, nor would it mean that such system could outperform classical computers in tasks other than the one used to determine a QA. In addition, the definitions and expectations with respect to what constitutes QA and LFTQC, including the anticipated stages of quantum technology maturation, may continue to evolve and may also diverge from others in the industry. Quantum computing technology, including QA and LFTQC, may take years or decades to be realized, if ever.

In addition, the standards by which we measure our progress may be based on assumptions and expectations that are not accurate or that may change as quantum computing evolves. For example, we measure the performance of our systems by gate fidelity and median gate speed, among other ways, as part of our internal testing. There may be other measures that are utilized in the future to measure our progress and the progress of others in the industry and, therefore, undue reliance should not be placed on our current performance measures. Further, we currently utilize different types of gates, including CZ and iSWAP, and may, in the future, choose different gate sets. At the moment, there is no standard set of gates agreed on in the industry, and there may never be. Furthermore, other standards for measurement may emerge to measure quantum gate fidelity or performance of quantum computers generally. Accordingly, undue reliance should not be placed on the fidelity measures that we present.

If we are unable to achieve an increase in the number of qubits or decrease in error rates on the timeframe that we anticipate, the availability of future generations of quantum computer systems may be materially delayed or may never occur. In the past we have failed to meet publicly announced milestones and may fail to meet projected milestones in the future. If our technology roadmap is delayed or never achieved, this would have a material impact on our business, financial condition or results of operations. See “We are in our early stages and have a limited operating history, which makes it difficult to forecast our future results of operations. We have in the past failed to meet publicly announced milestones and may fail to meet projected technological milestones in the future. In addition, we have in the past changed our technology roadmap, including the anticipated milestones and timing thereof.

Even if we complete development and achieve volume production of our quantum computers, if the cost, accuracy, performance characteristics or other specifications of our quantum computers fall short of our expectations, our business, financial condition and results of operations would be adversely affected.

We may expend our resources to pursue particular products, designs, sectors or investments and we may fail to capitalize on such products, designs, sectors or investments and/or forego other products, designs, sectors or investments that may have been more profitable or for which there may have been a greater likelihood of success.

Because we have limited financial and operational resources, we must prioritize our research and development for use of quantum computing within certain products, designs, sectors or investments. Correctly prioritizing our research and development activities is particularly important for us due to the breadth of companies building or seeking to build universal, gate-model quantum computing systems that can meet the requirements for solving commercial problems.

25

Table of Contents

As a result, we may forego or delay pursuit of opportunities in other products, designs, sectors or investments that later prove to have greater commercial potential and ability to achieve quantum advantage. For example, although we currently believe that quantum machine learning for finance is poised to be an early domain of quantum advantage through rapid value capture from quick integration, the risks associated with developing a product that can compute algorithms that scale efficiently to real-world size applications and will be applicable to multiple use cases and competition in creating such a product, among others, could outweigh the benefits.

We may fail to capitalize on the products, designs, sectors, or investments we choose to pursue, and our resource allocation decisions may cause us to forego viable or more profitable products, designs, sectors or investments, which would have an adverse effect on our business, prospects and financial results.

The quantum computing industry is in its early stages and volatile and is competitive on a global scale and we may not be successful in competing in this industry or establishing and maintaining confidence in our long-term business prospects among current and future partners and customers.

The markets in which we operate are rapidly evolving and highly competitive. As the marketplace continues to mature and new technologies and competitors enter, we expect competition to intensify. Our current competitors include:

large, well-established tech companies that generally compete across our products, including Google, Microsoft, Amazon and IBM;
large research organizations funded by sovereign nations such as China, Russia, Canada, Australia and the United Kingdom, and those in the European Union as of the date of this Annual Report on Form 10-K and we believe additional countries in the future;
less-established public and private companies with competing technology, including companies located outside the United States; and
new or emerging entrants seeking to develop competing technologies.

We compete based on various factors, including technology, performance, open architecture, multi-cloud availability, brand recognition and reputation, customer support and differentiated capabilities, including ease of administration and use, scalability and reliability, data governance and security. Many of our competitors have substantially greater brand recognition, customer relationships, and financial, technical and other resources, including an experienced sales force and customer service organization and sophisticated supply chain management. They may be able to respond more effectively than us to new or changing opportunities, technologies, standards, customer requirements and buying practices. In addition, many countries are focused on developing quantum computing solutions either in the private or public sector and may subsidize quantum computers which may make it difficult for us to compete. Many of these competitors do not face the same challenges we do in growing our business. In addition, other competitors might be able to compete with us by bundling their other products in a way that does not allow us to offer a competitive solution. Further, our competitors may win government contracts, and we may not.

Additionally, we must be able to achieve our objectives in a timely manner such that we do not lose ground to competitors, including competing technologies. For example, our competitors may achieve certain narrow and/or broad quantum milestones faster than us, which may negatively impact our business and prospects. Because there are a large number of market participants, including certain sovereign nations, focused on developing quantum computing technology, we must dedicate significant resources to achieving any technical objectives on the timelines established by our management team. Any failure to achieve objectives in a timely manner could adversely affect our business, operating results and financial condition.

In addition, the market for quantum computers is still rapidly evolving, characterized by rapidly changing technologies, competitive pricing and competitive factors, evolving government regulation and industry standards, and changing customer demands and behaviors. If the market for quantum computers in general does not develop as expected, develops more slowly than expected, develops in a manner that does not require use of our quantum computers, encounters negative publicity or if our quantum computers do not drive commercial engagement, then our business, prospects, financial condition and operating results could be harmed. If our clients and partners do not perceive the benefits of quantum computer solutions, or if our solutions do not drive member engagement, then demand for our products may not develop at all, or it may develop slower than we expect. If any of these events occur, it could have a material adverse effect on our business, financial condition or results of operations. If progress towards quantum advantage ever slows relative to expectations, it could adversely impact revenues and customer confidence to continue to pay for testing, access and “quantum readiness.” This would harm or even eliminate revenues in the period before quantum advantage.

For all of these reasons, the development of the market for quantum computers and competition may have a negative impact on our ability to maintain and grow demand for our platform or put downward pressure on our prices and gross margins, any of which could materially harm our reputation, business, results of operations, and financial condition.

We depend on a limited number of customers for a significant percentage of our revenue and the loss or temporary loss of a major customer for any reason could harm our financial condition.

We have historically generated most of our revenue from a limited number of customers. Revenue from U.S. government entities accounted for 48.0% and 54.2% of our total revenue for the years ended December 31, 2025 and 2024, respectively. Because of the concentrated nature of our customer base, our quarterly revenue and results of operations may fluctuate from quarter to quarter and are difficult to estimate, and any delay, reduction or cancellation of orders or services rendered or any acceleration or delay in anticipated purchases or grants and awards by our larger customers could materially affect our revenue and results of operations in any quarterly period. For further information regarding our customer concentration, refer to Note 15 of our audited consolidated financial statements for the year ended December 31, 2025, included elsewhere in this Annual Report on Form 10-K.

We may be unable to sustain or increase our revenue from our larger customers, grow revenues with new or other existing customers, or offset the discontinuation of concentrated purchases by our larger customers with purchases by new or existing customers. These larger customers could also reduce or discontinue their purchases of our products and services in the event they transition to internally developed products and services or determine to divide their purchases of our products and services between us and a second source. We expect that such concentrated purchases will continue to contribute materially to our revenue for the foreseeable future and that our results of operations may fluctuate materially as a result of such larger customers’ buying patterns or funding cycles. The loss or temporary loss of such customers, or a significant delay or reduction in their purchases, could materially harm our business, financial condition, results of operations and prospects.

A significant portion of our revenue currently depends on contracts with the public sector, and our failure to receive and maintain government contracts or changes in the contracting or fiscal policies of the public sector could have a material adverse effect on our business.

We have historically derived, and expect to continue to derive, a significant portion of our revenue from contracts with agencies of the U.S. federal and foreign governments, either directly by us or through other government contractors. For the years ended December 31, 2025, and 2024, sales to government entities comprised 90.2% and 89.4% of our total revenue, respectively.

Sales to government agencies involve risks that may not be present (or that are present to a lesser extent) with sales to non-governmental agencies. The bidding process for government contracts can be highly competitive, expensive, and time-consuming, often requiring significant upfront time and expense without any assurance that these efforts will generate revenue. These entities may also have increased purchasing power and leverage in negotiating contractual arrangements with us, as well as longer sales cycles, which brings the associated risk that substantial time and resources may be spent on a potential customer that elects not to purchase our products or services. Sales to government agencies are often fixed fee development contracts, which involve additional risks.

We also must comply with laws and regulations relating to the formation, administration, and performance of contracts, which provide public sector customers with rights, many of which are not typically found in commercial contracts. For instance, government contracts generally include the ability of government agencies to terminate early which, if exercised, would result in a lower contract value and lower the anticipated revenue generated by such arrangement. See “Contracts with U.S. government entities subject us to risks including early termination, audits, investigations, sanctions and penalties.” Our contracts with government agencies are typically structured in phases, with each phase subject to satisfaction of certain conditions. As a result, the actual scope of work performed pursuant to any such contracts, in addition to related contract revenue, could be less than total contract value. In addition, product purchases by such organizations are frequently subject to budget constraints, multiple approvals and unanticipated administrative, processing and other delays. Finally, these organizations typically have longer implementation cycles, require greater product functionality and scalability, require a broader range of services, demand that vendors take on a larger share of risks, require acceptance provisions that can lead to a delay in revenue recognition and expect greater payment flexibility. All of these factors can add further risk to business conducted with these potential customers and could lead to lower revenue results than originally anticipated.

In addition, our perceived relationship with the U.S. government could adversely affect our business prospects in certain non-U.S. geographies or with certain non-U.S. governments.

Accordingly, our business, financial condition, results of operations, and growth prospects may be adversely affected by certain events or activities, including, but not limited to:

Changes in government fiscal or procurement policies or government programs or applicable requirements, or decreases in government funding available for procurement of goods and services generally, or for our federal government contracts specifically;
Government entities exercising termination for convenience rights on our existing government contracts with such government entities;

27

Table of Contents

Restrictions on the grant of personnel security clearances to our employees;
Ability to maintain facility clearances required to perform on classified contracts for U.S. federal government and foreign government agencies;
Changes in the political environment, including before or after a change to the leadership within the government administration, and any resulting uncertainty or changes in policy or priorities and resultant funding;
Changes in the government’s attitude towards the capabilities that we offer, or us as a company or our platforms;
Appeals, disputes, or litigation relating to government procurement, including bid protests by unsuccessful bidders on potential or actual awards of contracts to us or our partners by the government;
The adoption of new laws or regulations or changes to existing laws or regulations;
Budgetary constraints, including automatic reductions as a result of “sequestration” or similar measures and constraints imposed by any lapses in appropriations for the federal government or certain of its departments and agencies;
Influence by, or competition from, third parties with respect to pending, new, or existing contracts with government customers;
Changes in political or social attitudes with respect to security or data privacy issues;
Potential delays or changes in the government appropriations or procurement processes, including as a result of events such as war, incidents of terrorism, natural disasters, and public health concerns or epidemics, such as the coronavirus pandemic; and
Increased or unexpected costs or unanticipated delays caused by other factors outside of our control.

Any of the foregoing events or activities, among others, could cause governments and governmental agencies to delay or refrain from entering into contracts with us and/or purchasing our computers in the future, reduce the size or timing of payments with respect to our services to, or purchases from, existing or new government customers, or otherwise have an adverse effect on our business, results of operations, financial condition, and growth prospects.

Our ability to commercialize our quantum computers in the future may be dependent upon our relationships with cloud providers.

We currently offer access to quantum computing as a service (“Quantum Computing as a Service” or “QCaaS”), both directly to our end users with our own Quantum Cloud Services (“QCS”) and indirectly to end users through public cloud providers such as Amazon Braket (“AWS”) and Microsoft Azure Quantum (“Azure”), who integrate our QCS into their own quantum computing platforms. These public cloud providers operate a service in direct competition with our providing direct access to QCS. In addition, we intend to partner with additional providers to provide access to our QCaaS. Cloud computing partnerships could be terminated, or not scale as anticipated, or at all.

There is risk that one or more of the public cloud providers, such as AWS and Azure, could use their respective control of their public clouds to control market pricing of the services, restrict access, embed innovations or privileged interoperating capabilities in competing products, bundle competing products and leverage their public cloud customer relationships to exclude us from opportunities. Further, these public cloud providers have the resources to acquire or partner with existing and emerging providers of competing technology and thereby accelerate adoption of those competing technologies, all of which could make it difficult or impossible for us to provide products and services that compete favorably with those of the public cloud providers.

Any material change in our contractual and other business relationships with our cloud providers could result in reduced use of our systems, increased expenses, including service credit obligations, and harm our brand and reputation, any of which could have a material adverse effect on our business, financial condition and results of operations. Further, if our contractual and other business relationships with our partners are terminated, either by the counterparty or by us, suspended or suffer a material change to which we are unable to adapt, such as the elimination of services or features on which we depend, we would be unable to provide our QCaaS business at the same scale and would experience significant delays and incur additional expense in transitioning customers to a different public cloud provider.

Currently, our customer agreement with AWS remains in effect until (i) terminated for convenience, which we may do for any reason by providing AWS notice and closing our account and which AWS may do for any reason by providing us at least 30 days’ notice or (ii) terminated for cause, which either party may do if the other party has an uncured material breach and which AWS may do immediately upon notice. Although alternative data center providers could host our business on a substantially similar basis to AWS, transitioning the cloud infrastructure currently hosted by AWS to alternative providers could potentially be disruptive, and we could incur significant one-time costs.

If we are unable to renew our agreement with AWS on commercially acceptable terms, our agreement with AWS is prematurely terminated, or it adds additional infrastructure providers, we may experience costs or downtime in connection with the transfer to, or the addition of, new data center providers. If AWS or other infrastructure providers increase the costs of their services, our business, financial condition, or results of operations could be materially and adversely affected.

Any material change in our contractual and other business relationships with our partners, could result in reduced use of our systems, increased expenses, including service credit obligations, and harm to our brand and reputation, any of which could have a material adverse effect on our business, financial condition and results of operations.

We depend on certain suppliers to source products. Failure to maintain our relationship with any of these suppliers, or a failure to replace any of these suppliers, could have a material adverse effect on our business, financial position, results of operations and cash flows.

Our ability to identify and develop relationships with qualified suppliers on commercial reasonable terms or at all who can satisfy our standards for quality and our need to access products and supplies in a timely and efficient manner is a significant challenge. Any failure to maintain our relationship with any of our key suppliers, or a failure to replace any such supplier that is lost, could have a material adverse effect on our business, financial position, results of operations and cash flows. We may be required to replace a supplier if their products do not meet our quality or safety standards. In addition, our suppliers could face reductions or interruptions in supply, or discontinue selling products at any time for reasons that may or may not be in our control or the suppliers’ control, including shortages of raw materials, environmental and social supply chain issues, global supply chain disruptions, pandemic, labor disputes or weather conditions. Disruptions in transportation lines or ongoing military conflicts and wars around the world, including related sanctions, may also cause global supply chain issues that affect us or our suppliers. We generally have multiple sources of supply, however, in some cases, materials are provided by a single supplier.

The loss of, or substantial decrease in the availability of, products from our suppliers, or the loss of a key supplier, temporarily or permanently, could result in a material shortage of products, which could lead to price escalations that we may be unable to offset by our prices to our customers. When supply chain issues are later resolved and prices return to normal levels, we may be required to reduce the prices at which we sell our products to our customers in order to remain competitive. In addition, even where these risks do not materialize, we may incur costs as we prepare contingency plans to address such risks. Our operating results and inventory levels could suffer if we are unable to promptly replace a supplier who is unwilling or unable to satisfy our requirements with a supplier providing similar products. In addition, our suppliers’ ability to deliver products may also be affected by raw material and commodity cost volatility or financing constraints caused by credit market conditions, which could materially and negatively impact our net sales and operating costs, at least until alternate sources of supply are arranged. Any delay or unavailability of key products required for our development activities could delay or prevent us from further developing our systems and applications on our expected timelines or at all.

Additionally, our business, financial position, results of operations and cash flows could be materially and adversely affected by our inability to continue sourcing products from our suppliers or as a result of issues in our supply chain. A weak or declining economy (including risks such as increased freight charges, raw material costs, electrical power costs and other associated expenses) could strain our suppliers, possibly resulting in supply disruption. In addition, there is a risk that our current or future suppliers, service providers, manufacturers or other partners may not survive such difficult economic times, which could directly affect our ability to attain our operating goals on schedule and on budget. Further, a failure to develop our supply chain management capabilities and recruit and retain qualified professionals, and a failure on our part to appropriately cancel, reschedule or adjust our requirements based on our business needs, could have an adverse impact on the availability of the supplies necessary to develop and manufacture our quantum computing solutions.

We have and may in the future enter into collaboration agreements and similar arrangements with third parties for the manufacturing of our products, and these agreements and similar arrangements may never achieve their anticipated goals, which may have a materially adverse impact on our business operations and our financial position or results of operations.

We rely on our current collaborative partners and third parties and may rely heavily on future collaborative partners and third parties to develop key, relevant algorithms and programming to make our quantum systems commercially viable. We have entered into, and may enter into, strategic partnerships to develop and commercialize our current and future research and development programs with other companies for purposes such as: obtaining expertise; obtaining sales and marketing services and/or support; obtaining equipment and facilities; developing relationships with potential future customers; and generating revenue.

For example, in February 2025, we entered into the Collaboration Agreement with Quanta for the development of certain components to be incorporated into our current and future quantum computers. If our work with Quanta does achieve the anticipated results, we may never realize the anticipated benefits of the Collaboration Agreement. In addition, pursuant to the Collaboration Agreement, each of the parties agreed to invest at least $250 million over the next five years in the field of quantum computing (and Quanta’s investment will be towards personnel and capital expenditures for developing products and services and manufacturing capability in furtherance of our product roadmap).

If the Collaboration Agreement is terminated before Quanta fulfills any or all of its investment commitment for any reason, we may not receive the anticipated benefits from the Collaboration Agreement. Further, we may not be successful in establishing or maintaining suitable partnerships in the future, and we may not be able to negotiate other collaboration agreements having satisfactory terms to us, or at all. Failure to make or maintain these arrangements or a delay or failure in a future collaborative partner’s performance under any such arrangements could harm our business and financial condition.

Our ability to compete successfully depends on continuous innovation, timely execution of our strategy, and achieving cost reductions and failure to do so could render our quantum computing systems obsolete or less competitive.

The quantum computing market is characterized by rapid technological change, changing user requirements, uncertain product lifecycles and evolving industry standards. Our future success depends on our ability to continue to innovate and increase customer adoption of our quantum solutions. If we are unable to enhance our quantum computing systems to keep pace with these rapidly evolving customer requirements, or if new technologies emerge that are able to deliver competitive products at lower prices, more efficiently, with better functionality, more conveniently, or more securely than our platform, our business, financial condition and results of operations could be adversely affected.

Even if we successfully develop our quantum computing solution and executing our strategy, customer preferences may change, or competitors may achieve technological breakthroughs in science, physics, or manufacturing that render our technology obsolete or inferior. While it is uncertain whether such breakthroughs will occur in the near term, they may occur eventually, and any such advancement could materially impact our business, financial condition or results of operations.

Our competitiveness also depends on our ability to reduce the cost per qubit over time, which assumes we will be able to achieve economies of scale related to demand for our computer systems, benefit from technological innovation, and negotiate favorable terms with third-party parts suppliers. If these anticipated cost savings do not materialize, we may be unable to achieve a lower cost per qubit, or if macroeconomic pressures such as inflation continue to increase labor and materials costs, we may be unable to price our quantum computers competitively, and this could have a material adverse effect on our business, financial condition or results of operations.

We could suffer disruptions, outages, defects and other performance and quality problems with our quantum computing systems, our production technology partners or with the public cloud, data centers and internet infrastructure on which we rely.

Our business depends on our quantum computing systems being available. We have experienced and may in the future experience, disruptions, outages, defects and other performance and quality problems with our systems. We have also experienced and may in the future experience, disruptions, outages, defects and other performance and quality problems with the public cloud and internet infrastructure on which our systems rely. These problems can be caused by a variety of factors, including failed introductions of new functionality, vulnerabilities and defects in proprietary and open-source software, hardware components, human error or misconduct, capacity constraints, design limitations, or denial of service attacks or other security-related incidents. We do not have a contractual right with our public cloud providers that compensates us for any losses due to availability interruptions in the public cloud.

Any disruptions, outages, defects and other performance and quality problems with our quantum computing systems or with the public cloud and internet infrastructure on which we rely, could result in reduced use of our systems, increased expenses, including service credit obligations, and harm to our brand and reputation, any of which could have a material adverse effect on our business, financial condition and results of operations.

We are highly dependent on our ability to attract and retain senior executive leadership and other key employees, such as quantum physicists, software engineers and other key technical employees, which is critical to our success. If we fail to retain talented, highly qualified senior management, engineers and other key employees or attract them when needed, such a failure could negatively impact our business.

Our future success is highly dependent on our ability to attract and retain our executive officers, key employees and other qualified personnel. As we build our brand and become more well known, there is an increased risk that competitors or other companies may seek to hire our personnel. A loss of a member of senior management, or an engineer or other key employee, particularly to a competitor, could have an adverse impact on our business strategy and place us at a competitive disadvantage.

Effective succession planning is important to our long-term success and may cause disruption to our business due to, among other things, diverting management’s attention away from the operations of the business or causing a deterioration in morale. Failure to ensure effective transfer of knowledge and smooth transitions involving key employees could hinder our strategic planning and execution.

Our future success also depends on our continuing ability to attract, develop, motivate, and retain highly qualified and skilled employees. The market for highly skilled workers and leaders in the quantum computing industry is extremely competitive. In particular, hiring qualified personnel specializing in supply chain management, engineering and sales, as well as other technical staff and research and development personnel is critical to our business and the development of our quantum computing systems. Many of the other companies with which we compete for qualified personnel have greater financial and other resources than we do.

The effective operation of our supply chain, including the acquisition of critical components and materials, the development and commercialization of our quantum computing technologies and the effective operation of our managerial and operating systems all depend upon our ability to attract, train and retain qualified personnel in the aforementioned specialties.

Additionally, changes in immigration and work permit laws and regulations or the administration or interpretation of such laws or regulations could impair our ability to attract and retain highly qualified employees. If we cannot attract, train and retain qualified personnel in this competitive environment, we may experience delays in the development of our quantum computing technologies and otherwise be unable to develop and grow our business as projected, or even at all.

Our quantum computing systems may not be compatible with some or all industry-standard software and hardware in the future, which could harm our business.

We have focused our efforts on creating quantum computing hardware, the operating system for such hardware, a suite of low-level software programs that optimize execution of quantum algorithms on our hardware, application programing interfaces (“APIs”) to access our systems, software development kits (“SDKs”) for system and application developers, and quantum programming languages for low- and high-level application developers. The industry is rapidly evolving, and customers have many choices for programming languages, application libraries, APIs, and SDKs, some of which may not be compatible with our own languages, APIs or SDKs. Our quantum computing solutions are designed today to be compatible with most major quantum software development kits, including Qiskit, Cirq, and Open QASM, all of which are open source. If a proprietary (not open source) software toolset became the standard for quantum application development in the future by a competitor, usage of our hardware might be limited as a result which would have a negative impact on the Company. Similarly, if a piece of hardware became a necessary component for quantum computing (for instance, quantum networking) and we cannot integrate with it the result might have a negative impact on the Company.

If our customers are unable to achieve compatibility between other software and hardware and our hardware, it could impact our relationships with such customers or with customers, generally, if the incompatibility is more widespread.

In addition, the mere announcement of an incompatibility problem relating to our products with higher level software tools could cause us to suffer reputational harm and/or lead to a loss of customers. Any adverse impacts from the incompatibility of our quantum computing solutions could adversely affect our business, operating results and financial condition.

If our information technology systems or data, or those of third parties upon which we rely, are or were compromised, we could experience adverse consequences, which may adversely affect our business.

In the ordinary course of our business, we and the third parties upon which we rely collect, receive, store, process, generate, use, transfer, disclose, make accessible, protect, secure, dispose of, transmit, and share (collectively, process), proprietary, confidential, and sensitive data, including personal data, intellectual property, controlled unclassified information and trade secrets (collectively, sensitive information). Cybersecurity incidents as well as natural disasters and other similar activities threaten the confidentiality, integrity, and availability of our sensitive information and information technology systems, and those of the third parties upon which we rely.

31

Table of Contents

Cybersecurity threats are prevalent in the technology industry and our customers’ industries and continue to rise, are increasingly difficult to detect, and come from a variety of sources, including traditional computer “hackers,” threat actors, “hacktivists,” organized criminal threat actors, personnel (such as through theft or misuse), sophisticated nation states, and nation-state-supported actors. The types of threats also continue to evolve, and may include social engineering attacks using AI tools, ransomware, and supply-chain attacks. Various techniques may be used to sabotage or to obtain unauthorized access to our platform, systems, networks, or physical facilities where our quantum computers are stored, and we may be unable to implement adequate preventative or mitigating measures. U.S. law enforcement agencies have indicated to us that quantum computing technology is of particular interest to certain malicious cyber threat actors, including nation-state-supported actors.

Remote work has become more common and has increased risks to our information technology systems and data, as more of our personnel utilize network connections, computers and devices outside our premises or network, including working at home, while in transit and in public locations. In addition, future or past business transactions (such as mergers and acquisitions) could expose us to additional cybersecurity risks and vulnerabilities, as our systems could be negatively affected by vulnerabilities present in merged or acquired entities’ systems and technologies as part of integration.

We rely on third-party service providers and technologies to operate critical business systems to process sensitive information in a variety of contexts. Our platform is built to be accessed through third-party public cloud providers such as AWS. These providers may also experience cybersecurity incidents and attacks to their products, which may impact our systems. Cybersecurity incidents may also result from non-technical means, such as actions by an employee with access to our systems. Our ability to monitor these third parties’ information security practices is limited, and these third parties may not have adequate information security measures in place. If our third-party service providers experience a cybersecurity incident or other interruption, we could experience adverse consequences. While we may be entitled to damages if our third-party service providers fail to satisfy their privacy or security-related obligations to us, any award may be insufficient to cover our damages, or we may be unable to recover such award.

We may expend significant resources or modify our business activities to try to protect against security incidents. Certain data privacy and security obligations require us to implement and maintain specific security measures to protect our information technology systems and sensitive information. While we and our third-party cloud providers have implemented security measures designed to protect against cybersecurity incidents, there can be no assurance that these measures will be effective, and these measures could fail or may be insufficient. Although we take steps designed to detect, mitigate, and remediate vulnerabilities in our information systems (such as our hardware and/or software, including that of third parties upon which we rely), we may not be able to detect and remediate all vulnerabilities on a timely basis because the threats and techniques used to exploit the vulnerability change frequently and are often sophisticated in nature. Therefore, such vulnerabilities could be exploited but may not be detected until after a cybersecurity incident has occurred.

In addition, applicable data privacy and security obligations may require us to notify relevant stakeholders, including affected individuals, customers, regulators, and investors of cybersecurity incidents. Such disclosures are costly, and the disclosure or the failure to comply with such requirements could lead to adverse consequences. Actual or perceived cybersecurity incidents affecting sensitive information about the Company, our partners, our customers or third parties could expose us and the parties affected to a risk of loss or misuse of this information, resulting in litigation and potential liability, paying damages, regulatory inquiries or actions, damage to our brand and reputation or other harm to our business. If we fail to detect or remediate a cybersecurity incident in a timely manner, or it otherwise affects our customers or impacts our ability to operate our platform, we may experience adverse consequences, such as government enforcement actions (for example, investigations, fines, penalties, audits, and inspections); additional reporting requirements and/or oversight; restrictions on processing sensitive information (including personal data); litigation (including class claims); indemnification obligations; negative publicity; material damage to our reputation; monetary fund diversions; diversions of management attention; interruptions in our operations (including availability of data); financial loss; and other similar harms.

Cybersecurity incidents and attendant consequences may cause customers to stop using our services, deter new customers from using our services, and negatively impact our ability to grow and operate our business. Cybersecurity incidents also may result in current or future competitors obtaining sensitive information, including proprietary information.

Our contracts may not contain limitations of liability, and even where they do, there can be no assurance that limitations of liability in our contracts are sufficient to protect us from liabilities, damages, or claims related to our data privacy and security obligations. We cannot be sure that our insurance coverage will be adequate or sufficient to protect us from or to mitigate liabilities arising out of our privacy and security practices, that such coverage will continue to be available on commercially reasonable terms or at all, or that such coverage will pay future claims.

Unstable or unfavorable market and economic conditions in our industry and or the global economy have had and may continue to have serious adverse consequences on our business, financial condition and share price. In the future, we may be required to record significant charges for impairment of our long-lived assets, other assets or investments.

At times in the past, the global economy, including credit and financial markets, has experienced extreme volatility and disruptions, including severely diminished liquidity and credit availability, declines in consumer confidence, declines in economic growth, increases in unemployment rates, increases in inflation rates, higher interest rates, bank failures and uncertainty about economic stability. Any volatility or disruptions in market and economic conditions may have adverse consequences on us or the third parties on whom we rely. If general economic conditions were to deteriorate or remain uncertain for an extended period, our liquidity may be harmed, and the trading price of our Common Stock could decline. In addition, negative general economic conditions, both in the U.S. and abroad, cause a decrease in business investments, including the progress on development of quantum technologies, and negatively affect the growth of our business.

If the equity and credit markets deteriorate, including as a result of political unrest or war, it may make any necessary financing more difficult to obtain in a timely manner or on favorable terms, more costly or more dilutive, and we could be forced to delay, reduce or eliminate our research and development programs and other efforts. Increased inflation rates have and are expected to adversely affect us by increasing our costs, including labor and employee benefit costs, and costs for equipment and system components associated with system development. In addition, higher inflation could also increase our customers’ operating costs, which could result in reduced budgets for our customers and potentially less demand for our systems. Additionally, if our customers are not successful in generating sufficient revenue or are unable to secure financing, they may not be able to pay, or may delay payment of, accounts receivable. Moreover, our key suppliers may reduce their output or become insolvent, thereby adversely impacting our ability to execute our research and development plans or manufacture our products. Any significant increases in inflation and related increase in interest rates could have a material adverse effect on our business, results of operations and financial condition.

If in the future a financial institution in which we hold funds fails or is subject to significant adverse conditions in the financial or credit markets, we could be subject to a risk of loss of all or a portion of such uninsured funds or be subject to a delay in accessing all or a portion of such uninsured funds. Any such loss or lack of access to these funds could adversely impact our short-term liquidity and ability to meet our operating expense obligations. Further, these events may make financings more difficult to obtain, and additional financing might not be available on reasonable terms, if at all; difficulties obtaining financing could have a material adverse effect on our financial condition, as well as our ability to continue to grow our operations.

Government actions and regulations, such as tariffs and trade protection measures, may limit our ability to obtain products from our suppliers or sell our products and services to customers. Political challenges between the United States and countries in which our suppliers are located, and changes to trade policies, including tariff rates and customs duties, trade relations between the United States and those countries and other macroeconomic issues could adversely impact our business. The United States administration has announced tariffs on certain products imported into the United States, and some countries have imposed tariffs in response to the actions of the United States. There is also a possibility of future tariffs, trade protection measures or other restrictions imposed on our products or on our customers by the United States or other countries that could have a material adverse effect on our business. Our technology may be deemed a matter of national security and as such our customer base may be tightly restricted. We may accept government grants that place restrictions on the business’ ability to operate.

An adverse change in market conditions, including a sustained decline in our stock price, negative changes to our position in the market, or lack of growth in demand for our products and services could be considered to be an impairment triggering event, which could impact valuation assumptions relating to the recoverability of assets and may result in impairment charges to our long-lived assets, other assets or investments, which would have a negative impact on our operating results. There are inherent uncertainties in management’s estimates, judgments and assumptions used in assessing recoverability of intangible and other long-lived assets. Any material changes in key assumptions, including failure to meet business plans, a deterioration in the U.S. and global financial markets, an increase in interest rates or an increase in the cost of equity financing by market participants within the industry or other unanticipated events and circumstances, may decrease our projected cash flows or increase discount rates and could potentially result in an impairment charge. From time to time, we may be required to record a significant charge to earnings in our consolidated financial statements during the period in which any impairment of our long-lived assets is determined, which might have a materially adverse impact on our business operations and our financial position or results of operations.

In the past we identified material weaknesses in our internal control over financial reporting, leading to a restatement of our financial statements for prior periods. These material weaknesses were subsequently remediated following implementation and testing of a series of new controls and procedures. If we identify additional material weaknesses or if we otherwise fail to establish and maintain effective control over financial reporting, it may adversely affect our ability to accurately and timely report our financial results in the future, and may adversely affect investor confidence, our reputation, our ability to raise additional capital and our business operations and financial condition.

A material weakness is a deficiency, or a combination of deficiencies, in internal control over financial reporting, such that there is a reasonable possibility that a material misstatement of a company’s annual or interim financial statements will not be prevented or detected on a timely basis. In the past we identified material weaknesses in our internal control over financial reporting, leading to a restatement of our financial statements for prior periods. These material weaknesses were subsequently remediated following implementation and testing of a series of new controls and procedures.

We cannot ensure that the measures we have taken to date, and actions we may take in the future, will prevent or avoid potential future material weaknesses due to a failure to implement and maintain adequate internal control over financial reporting or circumvention of these controls. In addition, in the future our controls and procedures may not be adequate to prevent or identify irregularities or errors or to facilitate the fair presentation of our financial statements.

Any failure to maintain effective controls could limit our ability to prevent or detect a misstatement of our accounts or disclosures that could result in additional material misstatements of our annual or interim financial statements. In such a case, we may be unable to maintain compliance with securities law requirements regarding timely filing of periodic reports in addition to the listing requirements of the Nasdaq. In addition, we could be subject to sanctions or investigations by the SEC, the Nasdaq Stock Market or other regulatory authorities as well as shareholder litigation which would require additional financial and management resources, and investors may lose confidence in our financial reporting and our stock price may decline as a result.

As a result, our ability to obtain any additional financing, or additional financing on favorable terms, could be materially and adversely affected, which in turn, could materially and adversely affect our business, financial condition and the market value of our Common Stock and require us to incur additional costs to improve our internal control systems and procedures. In addition, the perceptions of the Company among customers, suppliers, lenders, investors, securities analysts and others could also be adversely affected.

Our facilities or operations could be damaged or adversely affected as a result of prolonged power outages, natural disasters such as earthquakes, and other catastrophic events.

Our facilities or operations could be damaged or adversely affected by prolonged power outages natural disasters such as earthquakes, or other catastrophic events outside our control, which could cause us to miss publicly disclosed technology development milestones, cause delays in the development of our quantum computers or have other negative consequences. We cannot assure you that any backup systems will be adequate to protect us from the effects of fire, floods, typhoons, earthquakes, power loss resulting from such natural disasters, telecommunications failures, break-ins, war, riots, terrorist attacks or similar events. Any of the foregoing events may give rise to interruptions, breakdowns, system failures, technology platform failures or internet failures, which could cause us to miss publicly disclosed technology development milestones and cause delays in development and fabrication, the loss or corruption of data or malfunctions of software or hardware as well as adversely affect our ability to provide services. Any significant damage to our quantum research facilities or Fab-1 may disrupt our operations and could have a material adverse impact on our business, financial condition, results of operations and cash flows.

Risks Related to Our International Operations and Expansion

Because our success depends, in part, on our ability to expand sales internationally, our business will be susceptible to risks associated with international operations.

We currently maintain offices and have personnel in the United States, the United Kingdom, Australia and Canada. For the years ended December 31, 2025, and 2024, our non-U.S. revenue was approximately 47.3% and 41.4% of our total revenue, respectively. Any additional international expansion efforts that we may undertake may not be successful. In addition, conducting international operations subjects us to new risks, some of which we have not generally faced in the United States or other countries where we currently operate. These risks include, among other things: unexpected costs and errors in the localization of our platform and solutions; potential burden associated with complying with foreign laws and regulations; heightened regulatory requirements and costs associated therewith (including import/export control laws, tariffs, and cybersecurity and data privacy laws); difficulties associated with enforcing intellectual property rights in foreign jurisdictions; differing technology standards, pricing environments and lengths of sales cycles; increased financial reporting requirements and complexities; and challenges associated with staffing international operations and increased costs related thereto.

Additionally, operating in international markets also requires significant management attention and financial resources. We cannot be certain that the investment and additional resources required in establishing operations in other countries will produce desired levels of revenue or profitability.

We have limited experience in marketing, selling, and supporting our platform outside of the United States. If we invest substantial time and resources to expand our international operations and are unable to do so successfully and in a timely manner, our business, financial condition, revenues, results of operations or cash flows will suffer. In many countries, it is common for others to engage in business practices that are prohibited by our internal policies and procedures or other regulations applicable to us. Although we have implemented policies and procedures designed to ensure compliance with these laws and policies, there can be no assurance that all of our employees, contractors, partners and agents will comply with these laws and policies.

Our international sales and operations subject us to additional risks and costs, including the ability to engage with customers in new geographies, exposure to foreign currency exchange rate fluctuations, which can adversely affect our business, financial condition, revenues, results of operations or cash flows.

We derive a significant portion of revenue from our customers outside the United States. There are a variety of risks and costs associated with our international sales and operations, which may include making additional investments prior to the proven adoption of our solutions, the cost of conducting our business internationally and hiring and training international employees and the costs associated with complying with local law. Furthermore, we cannot predict the rate at which our platform and solutions will be accepted in international markets by potential customers.

We currently have sales, customer support and engineering personnel outside the United States in the United Kingdom, Australia and Canada. We believe our ability to attract new customers to purchase our QPUs or subscribe to our platform, or to attract existing customers to expand their purchase of our QPUs or to renew or expand their use of our platform, is directly correlated to the level of engagement we obtain with the customer. To the extent we are unable to effectively engage with non-U.S. customers due to our limited sales force capacity, we may be unable to effectively grow in international markets.

Given our international presence, we are exposed to the effects of fluctuations in currency exchange rates. While we have primarily transacted with customers in U.S. dollars, we expect to continue to generate some revenues, denominated in foreign currencies. Additionally, fluctuations in the value of the U.S. dollar and foreign currencies may make our QPUs or subscriptions more expensive for international customers, which could harm our business. Additionally, we incur expenses for employee compensation and other operating expenses at our non-U.S. locations in the local currency for such locations. Fluctuations in the exchange rates between the U.S. dollar and other currencies could result in an increase to the U.S. dollar equivalent of such expenses. These fluctuations could cause our results of operations to differ from our expectations or the expectations of our investors. Additionally, such foreign currency exchange rate fluctuations could make it more difficult to detect underlying trends in our business and results of operations.

Our international operations may subject us to greater than anticipated tax liabilities.

The amount of taxes we pay in different jurisdictions depends on the application of the tax laws of various jurisdictions, including the United States, to our international business activities, changes in tax rates, new or revised tax laws or interpretations of existing tax laws and policies, and our ability to operate our business in a manner consistent with our corporate structure and intercompany arrangements. The taxing authorities of the jurisdictions in which we operate may challenge our methodologies for pricing intercompany transactions pursuant to our intercompany arrangements or disagree with our determinations as to the income and expenses attributable to specific jurisdictions. If such a challenge or disagreement were to occur, and our position was not sustained, we could be required to pay additional taxes, interest, and penalties, which could result in one-time tax charges, higher effective tax rates, reduced cash flows, and lower overall profitability of our operations. Our financial statements could fail to reflect adequate reserves to cover such a contingency. Similarly, a taxing authority could assert that we are subject to tax in a jurisdiction where we believe we have not established a taxable connection, often referred to as a “permanent establishment” under international tax treaties, and such an assertion, if successful, could increase our expected tax liability in one or more jurisdictions.

Risks Related to Litigation and Government Regulation

We are subject to stringent and evolving U.S. state, federal and foreign laws, regulations and rules, contractual obligations, industry standards, policies and other obligations related to privacy, data use and security. Our actual or perceived failure to comply with such obligations could lead to regulatory investigations or actions; litigation; fines and penalties; disruptions of our business operations; reputational harm; loss of revenue or profits; loss of customers or sales; and otherwise, could adversely affect us and our business.

We collect, receive, store, process, generate, use, transfer, disclose, make accessible, protect, secure, dispose of, transmit, and share (collectively, “process”) personal data and other sensitive information. In the United States, federal, state, and local governments have enacted numerous data privacy and security laws, including data breach notification laws, personal data privacy laws, consumer protection laws, and other similar laws. In recent years, numerous U.S. states have enacted comprehensive privacy laws that impose certain obligations on covered businesses, including providing specific disclosures in privacy notices and their personal data rights.

As applicable, such rights may include the right to access, correct, or delete certain personal data, and to opt-out of certain data processing activities, such as targeted advertising, profiling, and automated decision-making. The exercise of these rights may impact our business and ability to provide our products and services. Certain jurisdictions also impose stricter requirements for processing certain personal data, including sensitive information, such as conducting data privacy impact assessments. These laws allow for statutory fines for noncompliance.

Our employees and personnel may use generative AI technologies to perform their work, and the disclosure and use of personal information in generative AI technologies is subject to various privacy laws and other privacy obligations. Additionally, several states and localities have enacted measures related to the use of AI and machine learning in products and services. These developments may further complicate compliance efforts and may increase legal risk and compliance costs for us, the third parties upon whom we rely, and our customers.

Outside of the United States, foreign governments also have similar or sometimes more stringent data protection laws. In particular, the United Kingdom’s GDPR (“UK GDPR”) imposes strict requirements for processing personal data. For example, under the UK GDPR, companies may face temporary or definitive bans on data processing and other corrective actions; fines of up to 17.5 million pounds or 4% of annual global revenue, whichever is greater; or private litigation related to processing of personal data brought by classes of data subjects or consumer protection organizations authorized at law to represent their interests. In Canada, the Personal Information Protection and Electronic Documents Act (“PIPEDA”) and various related provincial laws, as well as Canada’s Anti-Spam Legislation (“CASL”), may apply to our operations.

In the ordinary course of business, we may transfer personal data from the United Kingdom (UK), Canada, Australia and other jurisdictions to the United States or other countries. The UK and other jurisdictions have enacted laws requiring data to be localized or limiting the transfer of personal data to other countries. In particular, the UK has significantly restricted the transfer of personal data to the United States and other countries whose privacy laws it believes are inadequate. Other jurisdictions may adopt similarly stringent interpretations of their data localization and cross-border data transfer laws. Although there are currently various mechanisms that may be used to transfer personal data from the UK to the United States in compliance with law, such as the UK’s international data transfer addendum, these mechanisms are subject to legal challenges, and there is no assurance that we can satisfy or rely on these measures to lawfully transfer personal data to the United States.

If there is no lawful manner for us to transfer personal data from the UK or other jurisdictions to the United States, or if the requirements for a legally-compliant transfer are too onerous, we could face significant adverse consequences, including the interruption or degradation of our operations, the need to relocate part of or all of our business or data processing activities to other jurisdictions at significant expense, increased exposure to regulatory actions, substantial fines and penalties, the inability to transfer data and work with partners, vendors and other third parties, and injunctions against our processing or transferring of personal data necessary to operate our business. Additionally, companies that transfer personal data out of the UK to other jurisdictions, particularly to the United States, are subject to increased scrutiny from regulators, individual litigants, and activist groups.

We are also bound by contractual obligations related to data privacy and security, and our efforts to comply with such obligations may not be successful. For example, certain privacy laws, such as the UK GDPR and California Consumer Privacy Act (“CCPA”), require our customers to impose specific contractual restrictions on their service providers. We publish privacy policies, marketing materials and other statements, such as compliance with certain certifications or self-regulatory principles, regarding data privacy and security. If these policies, materials or statements are found to be deficient, lacking in transparency, deceptive, unfair, or misrepresentative of our practices, we may be subject to investigation, enforcement actions by regulators or other adverse consequences.

Table of Contents

Obligations related to data privacy and security are quickly changing, becoming increasingly stringent, and creating regulatory uncertainty. Additionally, these obligations may be subject to differing applications and interpretations, which may be inconsistent or conflict among jurisdictions. Preparing for and complying with these obligations requires us to devote significant resources, which may necessitate changes to our services, information technologies, systems, and practices and to those of any third parties that process personal data on our behalf. In addition, these obligations may require us to change our business model. We may at times fail (or be perceived to have failed) in our efforts to comply with our data privacy and security obligations. Moreover, despite our efforts, our personnel or third parties on whom we rely may fail to comply with such obligations, which could negatively impact our business operations.

If we or the third parties on which we rely fail, or are perceived to have failed, to address or comply with applicable data privacy and security obligations, we could face significant consequences, including but not limited to: government enforcement actions (e.g., investigations, fines, penalties, audits, inspections, and similar); litigation (including class-action claims); additional reporting requirements and/or oversight; bans on processing personal data; orders to destroy or not use personal data; and imprisonment of company officials.

Any of these events could have a material adverse effect on our reputation, business, or financial condition, including but not limited to: loss of customers; interruptions or stoppages in our business operations; interruptions or stoppages of data collection needed to train our algorithms; inability to process personal data or to operate in certain jurisdictions; limited ability to develop or commercialize our products; expenditure of time and resources to defend any claim or inquiry; adverse publicity; or substantial changes to our business model or operations.

Contracts with U.S. government entities subject us to risks including early termination, audits, investigations, sanctions and penalties.

We have several contracts with various government entities, including contracts with the Defense Advanced Research Project Agency and the Department of Energy, among others, and we may enter into additional contracts with U.S. government entities in the future, which subjects our business to statutes and regulations applicable to companies’ doing business with the government, including the Federal Acquisition Regulation. These government contracts customarily contain provisions that give the government substantial rights and remedies, many of which are not typically found in commercial contracts, and which are unfavorable to contractors. For instance, most U.S. government agencies include provisions that allow the government to unilaterally terminate or modify contracts for convenience, and in that event, the counterparty to the contract may generally recover only its incurred or committed costs and settlement expenses and profit on work completed prior to the termination. If the government terminates a contract for default, the defaulting party may be liable for any extra costs incurred by the government in procuring undelivered items from another source.

In addition, government contracts normally contain additional requirements that may increase our costs of doing business, reduce our profits, and expose us to liability for failure to comply with these terms and conditions. These requirements include, for example:

specialized disclosure and accounting requirements unique to government contracts;
cybersecurity safeguards and assessments beyond what are typically required by commercial equivalents;
financial and compliance audits that may result in potential liability for price adjustments, recoupment of government funds after such funds have been spent, civil and criminal penalties, or administrative sanctions such as suspension or debarment from doing business with the U.S. government;
public disclosures of certain contract and company information; and
mandatory socioeconomic compliance requirements, including labor requirements, non-discrimination and affirmative action programs and environmental compliance requirements.

Government contracts are also generally subject to greater scrutiny by the government, which can initiate reviews, audits and investigations regarding our compliance with government contract requirements. In addition, if we fail to comply with government contracting laws, regulations and contract requirements, our contracts may be subject to termination, and we may be subject to financial and/or other liability under our contracts, the Federal Civil False Claims Act (including treble damages and other penalties), or criminal law. In particular, the False Claims Act’s “whistleblower” provisions also allow private individuals, including present and former employees, to sue on behalf of the U.S. government. Further, the False Claims Act has increasingly had enforcement actions for non-adherence to government contracts’ technology (including cybersecurity) provisions. Any penalties, damages, fines or suspension could adversely affect our ability to operate our business and our financial results.

Table of Contents

We are subject to U.S. and foreign anti-corruption, anti-bribery and similar laws, and non-compliance with such laws can subject us to criminal or civil liability and harm our business.

We are subject to the U.S. Foreign Corrupt Practices Act of 1977, as amended, the U.S. domestic bribery statute contained in 18 U.S.C. § 201, the U.S. Travel Act, and other anti-bribery, and anti-corruption laws in countries in which we conduct activities. Anti-corruption and anti-bribery laws have been enforced aggressively in recent years and are interpreted broadly to generally prohibit companies, their employees, and their third-party intermediaries from authorizing, promising, offering, providing, soliciting, or accepting, directly or indirectly, improper payments or benefits to or from any person whether in the public or private sector. We may engage with partners and third-party intermediaries to market our services and to obtain necessary permits, licenses, and other regulatory approvals. In addition, we or our third-party intermediaries may have direct or indirect interactions with officials and employees of government agencies or state-owned or affiliated entities.

We can be held liable for the corrupt or other illegal activities of these third-party intermediaries, and of our employees, representatives, contractors, partners, and agents, even if we do not explicitly authorize such activities. We cannot provide any assurance that all of our employees and agents will not take actions in violation of our policies and applicable law, for which we may be ultimately held responsible.

Detecting, investigating, and resolving actual or alleged violations of anti-corruption laws can require a significant diversion of time, resources, and attention from senior management. In addition, noncompliance with anti-corruption or anti-bribery laws could subject us to whistleblower complaints, investigations, sanctions, settlements, prosecution, enforcement actions, fines, damages, other civil or criminal penalties, injunctions, suspension or debarment from contracting with certain persons, reputational harm, adverse media coverage, and other collateral consequences.

We are subject to government export and import controls that could impair our ability to compete in international markets due to licensing requirements and subject us to liability if we are not in compliance with applicable laws.

Our products and technologies are subject to U.S. export control and import laws and regulations, including the U.S. Export Administration Regulations, U.S. Customs regulations, and various economic and trade sanctions regulations administered by the U.S. Treasury Department’s Office of Foreign Assets Controls. U.S. export control and economic sanctions laws include restrictions or prohibitions on the sale or supply of certain products, technologies, and services to U.S. Government embargoed or sanctioned countries, governments, persons and entities. In addition, certain of our products and technology are subject to export licensing or approval requirements. Exports of our products and technology must be made in compliance with export control and sanctions laws and regulations. If we fail to comply with these laws and regulations, we and certain of our employees could be subject to substantial civil or criminal penalties, including the possible loss of export or import privileges; fines, which may be imposed on us and responsible employees or managers; and, in extreme cases, the incarceration of responsible employees or managers.

In addition, changes in our products or technologies or changes in applicable export or import laws and regulations may create delays in the introduction and sale of our products and technologies in international markets or, in some cases, prevent the export or import of our products and technologies to certain countries, governments or persons altogether. Any change in export or import laws and regulations, shift in the enforcement or scope of existing laws and regulations, or change in the countries, governments, persons or technologies targeted by such laws and regulations, could also result in decreased use of our products and technologies, or in our decreased ability to export or sell our products and technologies to existing or potential customers. Any decreased use of our products and technologies or limitation on our ability to export or sell our products and technologies would likely adversely affect our business, financial condition and results of operations.

Further, the operation of our products within a fully operational quantum system may depend on products and technologies supplied by third parties. Changes in third party products or technologies or changes in applicable export or import laws and regulations may create delays in the introduction and sale of our products and technologies to customers or, in some cases, prevent sales of our products and technologies to certain countries, governments or persons altogether. Any change in export or import laws and regulations, shift in the enforcement or scope of existing laws and regulations, or change in the countries, governments, persons or technologies targeted by such laws and regulations, could also result in decreased use of our products and technologies, or in our decreased ability to sell our products and technologies to existing or potential customers. Any decreased use of our products and technologies or limitation on our ability to sell our products and technologies would likely adversely affect our business, financial condition and results of operations.

We expect to incur significant costs in complying with these regulations. Regulations related to quantum computing are currently evolving and we face risks associated with changes to these regulations.

Table of Contents

Our business is exposed to risks associated with litigation, investigations and regulatory proceedings.

We may in the future face legal, administrative and regulatory proceedings, claims, demands and/or investigations involving stockholder, consumer, competition and/or other issues relating to our business on a global basis. Litigation and regulatory proceedings are inherently uncertain, and adverse rulings could occur, including monetary damages, or an injunction stopping us from engaging in certain business practices, or requiring other remedies, such as compulsory licensing of patents. An unfavorable outcome or settlement may result in a material adverse impact on our business, results of operations, financial position and overall trends. In addition, regardless of the outcome, litigation can be costly, time-consuming, and disruptive to our operations. Any claims or litigation, even if fully indemnified or insured, could damage our reputation and make it more difficult to compete effectively or to obtain adequate insurance in the future. In addition, the laws and regulations our business is subject to are complex and change frequently. We may be required to incur significant expense to comply with changes in, or remedy violations of, these laws and regulations.

Furthermore, while we maintain insurance for certain potential liabilities, such insurance does not cover all types and amounts of potential liabilities and is subject to various exclusions as well as caps on recoverable amounts. Even if we believe a claim is covered by insurance, insurers may dispute our entitlement to recovery for a variety of potential reasons, which may affect the timing and, if the insurers prevail, the amount of our recovery.

We may become subject to product liability claims, which could harm our financial condition and liquidity if we are not able to successfully defend or insure against such claims.

We may become subject to product liability claims, even those without merit, which could harm our business prospects, operating results, and financial condition. We may face an inherent risk of exposure to claims in the event our quantum computers do not perform as expected or malfunction. A successful product liability claim against us could require us to pay a substantial monetary award. Moreover, a product liability claim could generate substantial negative publicity about our quantum computers and business and inhibit or prevent the commercialization of other future quantum computers, which would have material adverse effects on our brand, business, prospects and operating results. Any insurance coverage might not be sufficient to cover all potential product liability claims. Any lawsuit seeking significant monetary damages either in excess of our coverage, or outside of our coverage, may have a material adverse effect on our reputation, business and financial condition. We may not be able to secure additional product liability insurance coverage on commercially acceptable terms or at reasonable costs when needed, particularly if we do face liability for our products and are forced to make a claim under our policy.

We are subject to requirements relating to environmental and safety regulations and environmental remediation matters, which could adversely affect our business, results of operations and reputation.

We are subject to numerous federal, state and local environmental laws and regulations governing, among other things, solid and hazardous waste storage, treatment and disposal, and remediation of releases of hazardous materials. There are significant capital, operating and other costs associated with compliance with these environmental laws and regulations. Environmental laws and regulations may become more stringent in the future, which could increase costs of compliance or require us to manufacture with alternative technologies and materials.

Federal, state and local authorities also regulate a variety of matters, including, but not limited to, health, safety and permitting in addition to the environmental matters discussed above. New legislation and regulations may require us to make material changes to our operations, resulting in significant increases to the cost of production.

Our manufacturing process will have hazards such as but not limited to hazardous materials, machines with moving parts, and high voltage and/or high current electrical systems typical of large manufacturing equipment and related safety incidents. There may be safety incidents that damage machinery or product, slow or stop production, or harm employees. Consequences may include litigation, regulation, fines, increased insurance premiums, mandates to temporarily halt production, workers’ compensation claims, or other actions that impact our brand, finances, or ability to operate.

Changes in tax laws or regulations that are applied adversely to us may have a material adverse effect on our business, cash flow, financial condition, or results of operations.

New tax laws, statutes, rules, regulations, or ordinances could be enacted at any time. Further, existing tax laws, statutes, rules, regulations, or ordinances could be interpreted differently, changed, repealed, or modified. Any such enactment, interpretation, change, repeal or modification could adversely affect us, possibly with retroactive effect. In particular, changes in corporate tax rates, the taxation of foreign earnings and the deductibility of expenses under current law or any future tax reform legislation could have a material impact on the value or realization of our net deferred tax assets, result in significant one-time charges, and increase our future tax expenses.

Risks Related to Intellectual Property

Any failure to obtain, maintain and protect our intellectual property rights could impair our ability to protect and commercialize our proprietary products and technology and cause us to lose our competitive advantage.

Our success depends, in significant part, on our ability to obtain, maintain, enforce and defend our intellectual property rights, including patents and trade secrets. We rely upon a combination of the intellectual property protections afforded by patent, copyright, trademark and trade secret laws in the United States and other jurisdictions, as well as license agreements and other contractual protections, to establish, maintain and enforce rights in our proprietary technologies. In addition, we seek to protect our intellectual property rights through nondisclosure and invention assignment agreements with our employees and consultants, and through non-disclosure agreements with business partners and other third parties.

However, we may not be able to prevent unauthorized use of our intellectual property. Our trade secrets may also be compromised, which could cause us to lose our competitive advantage. Third parties may attempt to copy or otherwise obtain, use or infringe our intellectual property.

Monitoring and detecting unauthorized use of our intellectual property is difficult and costly, and the steps we have taken or will take to prevent infringement or misappropriation may not be sufficient. Any enforcement efforts we undertake, including litigation, could be time-consuming and expensive and could divert management’s attention, which could harm our business, results of operations, and financial condition. In addition, existing intellectual property laws and contractual remedies may afford less protection than needed to safeguard our intellectual property portfolio, and third parties may develop competitive offerings in a manner that leaves us with limited means to enforce our intellectual property rights against them.

Patent, copyright, trademark and trade secret laws vary significantly throughout the world. A number of foreign countries do not protect intellectual property rights to the same extent as do the laws of the United States. Therefore, our intellectual property rights may not be as strong or as easily enforced outside of the United States and efforts to protect against the unauthorized use of our intellectual property rights, technology and other proprietary rights may be more expensive and difficult outside of the United States.

Failure to adequately protect our intellectual property rights could result in our competitors using our intellectual property to offer products, potentially resulting in the loss of some of our competitive advantage and a decrease in our revenue, which would adversely affect our business, financial condition and operating results.

Our inability to secure patent protection or enforce our patent rights could have a material adverse effect on our ability to prevent others from commercializing similar products or technology.

The application and registration of patents involves complex legal and factual questions. As a result, we cannot be certain that the patent applications that we file will result in patents being issued, or that our patents and any future patents that do issue will afford protection against competitors with similar technology. Numerous patents and pending patent applications owned by others exist in the fields in which we have developed and are developing our technology, and this may make it difficult for us to obtain certain patent coverage on our own. Any of our existing or pending patents may also be challenged by others on the basis that they are otherwise invalid or unenforceable. Furthermore, patent applications filed in foreign countries are subject to laws, rules and procedures that differ from those of the United States, and thus we cannot be certain that foreign patent applications related to issued U.S. patents will be issued.

Even if our patent applications succeed, it is still uncertain whether these patents will be contested, circumvented, invalidated or limited in scope in the future. The rights granted under any issued patents may not provide us with meaningful protection or competitive advantages. The intellectual property rights of others could bar us from licensing and exploiting any patents that issue from our pending applications, and the claims under any patents that issue from our patent applications may not be broad enough to prevent others from developing technologies that are similar or that achieve results similar to ours. In addition, patents issued to us may be infringed upon or designed around by others and others may obtain patents that require license or design around, either of which would increase costs and may adversely affect our business, prospects, financial condition and operating results.

We may face patent infringement and other intellectual property claims that could be costly to defend, result in injunctions and significant damage awards, or limit our ability to use certain key technologies in the future, all of which could harm our business.

Our success depends, in part, on our ability to develop and commercialize our products, services and technologies without infringing, misappropriating or otherwise violating the intellectual property rights of third parties. However, we may not be aware that our products, services or technologies are infringing, misappropriating or otherwise violating third-party intellectual property rights and such third parties may bring claims alleging such infringement, misappropriation or violation.

40

Table of Contents

For example, there may be issued patents of which we are unaware, held by third parties that, if found to be valid and enforceable, could be alleged to be infringed by our current or future products, services or technologies. Also, because patent applications can take years to issue and are often afforded confidentiality for some period of time, there may currently be pending applications, unknown to us, that later result in issued patents that could cover our current or future products, services or technologies. The strength of our defenses will depend on the rights asserted, the interpretation of these rights, and our ability to invalidate the asserted rights. However, we could be unsuccessful in advancing non-infringement and/or invalidity arguments in our defense. Companies that have developed and are developing technology are often required to defend against litigation claims based on allegations of infringement, misappropriation or other violations of intellectual property rights. Our products, services or technologies may not be able to withstand third-party claims against their use. In addition, as compared to us, many companies have the capability to dedicate substantially greater resources to enforce their intellectual property rights and to defend claims that may be brought against them.

If a third party is able to obtain an injunction preventing us from using or accessing such third-party intellectual property rights, or if we cannot license or develop alternative technology for any infringing aspect of our business, we may be forced to limit or stop sales of our products, services or technologies or cease business activities related to such intellectual property.

Although we carry general liability insurance, our insurance may not cover potential claims of this type or may not be adequate to indemnify us for all liability that may be imposed. We cannot predict the outcome of lawsuits and cannot ensure that the results of any such actions will not have an adverse effect on our business, financial condition or results of operations. Even if the claims do not result in litigation or are resolved in our favor, these claims, and the time and resources necessary to resolve them, could divert the resources of our management and harm our business and operating results. Further, there could be public announcements of the intellectual property litigation, and if securities analysts, investors or others perceive the potential impact to be negative or risks to be substantial, it could have an adverse effect on the price of our Common Stock.

Any intellectual property litigation to which we might become a party, or for which we are required to provide indemnification, regardless of the merit of the claim or our defenses, may require us to do one or more of the following:

cease selling or using solutions or services that incorporate the intellectual property rights that allegedly infringe, misappropriate or violate the intellectual property of a third party;
make substantial payments for legal fees, settlement payments or other costs or damages;
obtain a license, which may not be available on reasonable terms or at all, to sell or use the relevant technology;
redesign the allegedly infringing solutions to avoid infringement, misappropriation or violation, which could be costly, time-consuming or impossible; or
indemnify third parties using our products or services.

The occurrence of infringement claims may grow as the market for our products, services and technologies grows. Accordingly, our exposure to damages resulting from infringement claims could increase and this could further exhaust our financial and management resources.

We rely on certain open-source software in our quantum systems. If licensing terms change, our business may be adversely affected.

Our platform utilizes software licensed to us by third-party authors under “open-source” licenses and we expect to continue to utilize open-source software in the future. The use of open-source software may entail greater risks than the use of third-party commercial software, as open-source licensors generally do not provide warranties or other contractual protections regarding infringement claims or the quality of the code. To the extent that our platform depends upon the successful operation of the open-source software we use, any undetected errors or defects in this open-source software could prevent the deployment or impair the functionality of our platform, delay new solution introductions, result in a failure of our platform and injure our reputation. For example, undetected errors or defects in open-source software could render the platform and broader systems vulnerable to cybersecurity incidents.

Furthermore, some open-source licenses require the release of proprietary source code combined with, linked to or distributed with such open-source software to be released to the public. If we combine, link or distribute our proprietary software with open-source software in a specific manner, we could, under some open-source licenses, be required to release the source code of our proprietary software to the public. This would allow our competitors to create similar solutions with lower development effort and time and ultimately put us at a competitive disadvantage.

Although we monitor our use of open-source software to avoid subjecting our platform to conditions we do not intend to attach to such platform or our proprietary code, we cannot assure you that our processes for controlling such use will be effective.

If we are held to have breached the terms of an open-source software license, we could be required to seek licenses from third parties to continue operating using our solution on terms that are not economically feasible, to re-engineer our solution or the supporting computational infrastructure to discontinue use of code, or to make generally available, in source code form, portions of our proprietary code. This could allow our competitors to create similar solutions with lower development effort and time and ultimately put us at a competitive disadvantage.

Some of our intellectual property has been or may be conceived or developed through government-funded research and thus may be subject to federal regulations providing for certain rights for the U.S. government or imposing certain obligations on us, such as a license to the U.S. government under such intellectual property, “march-in” rights, certain reporting requirements and a preference for U.S.-based companies, and compliance with such regulations may limit our exclusive rights and our ability to contract with non-U.S. manufacturers.

The U.S. government may have certain rights to intellectual property embodied in our current or future intellectual property pursuant to the Bayh-Dole Act of 1980, or the Patent and Trademark Law Amendments Act. These U.S. government rights include a non-exclusive, non-transferable, irrevocable worldwide license to use inventions for any governmental purpose. In addition, the U.S. government has the right, under certain limited circumstances, to require the licensor to grant exclusive, partially exclusive or non-exclusive licenses to any of these inventions to a third party if it determines that (1) adequate steps have not been taken to commercialize the invention, (2) government action is necessary to meet public health or safety needs or (3) government action is necessary to meet requirements for public use under federal regulations (also referred to as “march-in” rights).

The U.S. government also has the right to take title to these inventions if the licensor fails to disclose the invention to the government or fails to file an application to register the intellectual property within specified time limits. Intellectual property generated under a government funded program is also subject to certain reporting requirements, compliance with which may require us to expend substantial resources. In addition, the U.S. government requires that any products embodying any of these inventions or produced through the use of any of these inventions be manufactured substantially in the United States, and some of our license agreements require that we comply with this requirement.

This preference for U.S. industry may be waived by the federal agency that provided the funding if the owner or assignee of the intellectual property can show that reasonable but unsuccessful efforts have been made to grant licenses on similar terms to potential licensees that would be likely to manufacture the products substantially in the United States or that under the circumstances domestic manufacture is not commercially feasible. To the extent any of our owned or licensed future intellectual property is also generated through the use of U.S. government funding, the provisions of the Bayh-Dole Act may similarly apply.

Risks related to an Investment in our Securities and other General Matters

The market price of our Common Stock and Public Warrants has been and may continue to be volatile.

The price of our Common Stock and Public Warrants has been and may continue to be volatile and has and may fluctuate or decline significantly in response to numerous factors, some of which are beyond our control. The securities markets have experienced and continue to experience significant volatility. As a result of this volatility, investors in our Common Stock may not be able to sell their shares at or above the prices they paid. Further, as a result of this volatility it may be difficult for us to attract new investments, including additional offerings of our securities, on terms we consider reasonable, or at all.

In the twelve-month period ended December 31, 2025, the market price of our Common Stock varied between a high of $58.15 on October 14, 2025 and a low of $5.95 on January 13, 2025, and the market price of our Public Warrants varied between a high of $46.78 on October 15, 2025 and a low of $1.95 on January 13, 2025. Market volatility, as well as general economic, market or political conditions, could reduce the market price of shares of our Common Stock or Public Warrants regardless of our operating performance. Further, our Common Stock could be traded by short sellers, which may put pressure on the supply and demand for our Common Stock, further influencing volatility in its market price.

Table of Contents

Our operating results could be below the expectations of public market analysts and investors due to a number of potential factors, including: our ability to meet our technological milestones (in a timely fashion or at all); changes in the industries in which we and our customers operate; the relative performance of our competitors; adverse impacts of global military conflicts and wars; anticipated or actual fluctuations in our operating results; publication of research reports by securities analysts about us or our competitors or our industry; rumors and market speculation involving us or our competitors, which may include short seller reports; the public’s reaction to our press releases, public announcements and filings with the SEC; our or our competitors’ failure to meet analyst projections or guidance; additions and departures of key personnel; changes in laws or regulations affecting our business, including accounting standards, policies, guidelines, interpretations and principles; involvement in litigation involving the Company, or actions by institutional or activist stockholders; future sales or issuances of our securities; the volume of our securities available for public sale or resale; and other events or factors, including recessions, increases in inflation and interest rates, disruptions to banking systems, foreign currency fluctuations, international tariffs, social, political and economic risks, natural disasters, acts of war (including the conflict involving Russia and Ukraine), terrorism or responses to such events. These market and industry factors may materially reduce the market price of our Common Stock and our Public Warrants regardless of the operating performance of the Company. In the past, following periods of market volatility, stockholders have instituted securities class action litigation. If we are involved in securities litigation, it could have a substantial cost and divert resources and the attention of executive management from our business regardless of the outcome of such litigation.

We are currently a “well-known seasoned issuer” as defined in Rule 405 of the Securities Act because our non-affiliated common stock public float was above $700.0 million as of the relevant determination date. If at a specific measurement time in the future, our public float is below $700.0 million, we may no longer qualify as a well-known seasoned issuer and would no longer be able to file automatic shelf registration statements on Form S-3ASR and enjoy the benefits associated with such registration statements, such as automatic effectiveness immediately upon filing, permitting companies to omit more information from the base prospectus than permitted for other shelf registration statements, allowing companies to register unspecified amounts of securities and doing so without allocating among securities or between primary and secondary offerings, and permitting companies to pay filing fees on a “pay-as-you-go” basis at the time of each takedown from the shelf registration statement.  We would also need to convert any Forms S-3ASR to non-automatic shelf registration statements. Not qualifying as a well-known seasoned issuer could also impact the views or perceptions of investors and analysts and may influence investors’ willingness to purchase or hold our securities or analysts’ recommendations regarding our securities.

We may fail to comply with the rules that apply to public companies, including Section 404 of the Sarbanes-Oxley Act, which could result in sanctions or other penalties that would adversely impact our business.

As a public company, and particularly after we are no longer an “emerging growth company,” we have and will continue to incur significant legal, accounting, and other expenses that we did not incur as a private company, including costs resulting from public company reporting obligations under the Securities Act or the Exchange Act, and regulations regarding corporate governance practices.

The Sarbanes-Oxley Act, the Dodd-Frank Wall Street Reform and Consumer Protection Act, the rules of the SEC, the listing requirements of the Nasdaq, and other applicable securities rules and regulations impose various requirements on public companies, including establishment and maintenance of effective disclosure and financial controls and corporate governance practices. These requirements have increased our legal and financial compliance costs and made some activities more time-consuming and costly. Changes we have made and any changes we make in the future to comply with these obligations may not be sufficient to allow us to satisfy our obligations as a public company on a timely basis, or at all.

These reporting requirements, rules and regulations, coupled with the increase in potential litigation exposure associated with being a public company, could also make it more difficult for us to attract and retain qualified persons to serve on our board of directors (the “Board”) or board committees or to serve as executive officers, or to obtain certain types of insurance, including directors’ and officers’ insurance, on acceptable terms. Pursuant to Sarbanes-Oxley Act Section 404, we are required to furnish a report by our management on our internal control over financial reporting in our Annual Reports on Form 10-K with the SEC. However, while we remain an emerging growth company, we are not required to include an attestation report on internal control over financial reporting issued by our independent registered public accounting firm.

43

Table of Contents

To achieve compliance with Sarbanes-Oxley Act Section 404, we engaged in a process to enhance our internal control over financial reporting, which was both costly and challenging. Despite our efforts, there is a risk that we will not be able to conclude in the future, that our internal control over financial reporting is effective as required by Sarbanes-Oxley Act Section 404. See In the past we identified material weaknesses in our internal control over financial reporting, leading to a restatement of our financial statements for prior periods. These material weaknesses were subsequently remediated following implementation and testing of a series of new controls and procedures. If we identify additional material weaknesses or if we otherwise fail to establish and maintain effective control over financial reporting, it may adversely affect our ability to accurately and timely report our financial results in the future, and may adversely affect investor confidence, our reputation, our ability to raise additional capital and our business operations and financial condition.

Our quarterly operating results have and may fluctuate significantly and could fall below the expectations of securities analysts and investors due to many factors, some of which are beyond our control, resulting in a decline in our stock price.

Our quarterly operating results have and may fluctuate significantly because of several factors, including:

labor availability and costs for hourly and management personnel;
profitability of our products, especially in new markets and due to seasonal fluctuations;
changes in interest rates;
impairment of long-lived assets;
macroeconomic conditions, both nationally and locally;
negative publicity relating to our products;
changes in consumer preferences and competitive conditions; and
expansion to new markets.

Securities research analysts have and may establish and publish their own periodic projections for us. These projections may vary widely and may not accurately predict the results we actually achieve. Our share price may decline if our actual results do not match the projections of these securities research analysts. Similarly, if one or more of the analysts who write reports on us downgrades our stock or publishes inaccurate or unfavorable research about our business, our share price could decline. If one or more of these analysts fails to publish reports on us regularly, our share price or trading volume could decline. If analysts cease coverage of us, the market price and volume for our securities could be adversely affected.

Future sales or issuances of our securities may adversely affect the market price of our securities and may be dilutive to existing securities holders.

Sales of a substantial number of shares of our Common Stock in the public market, including sales of our Common Stock by us or our affiliates, or the perception that these sales may occur, could reduce the market price of our Common Stock.

We cannot predict the size or timing of any future sales or issuances of our securities or the effect, if any, that such future sales or issuances could have on the market price of our securities. As a result, future capital raising efforts may reduce the market price of our Common Stock and be dilutive to existing stockholders. In addition, our ability to raise additional capital through the sale of equity or convertible debt securities could be significantly impacted by the resale of shares of Common Stock by selling securityholders, which could result in a significant decline in the trading price of our Common Stock and potentially hinder our ability to raise capital at terms that are acceptable to us or at all.

In addition, we may issue additional shares of Common Stock from time to time, including under our equity incentive plans or employee stock purchase plan, or preferred stock. Common Stock reserved for future issuance under our equity incentive plans will become eligible for sale in the public market once those shares are issued, subject to provisions relating to various vesting agreements and, in some cases, limitations on volume and manner of sale applicable to affiliates under Rule 144, as applicable.

In addition, we have filed and may file in the future one or more registration statements on Form S-8 under the Securities Act to register additional shares of Common Stock or securities convertible into or exchangeable for shares of Common Stock issued pursuant to our equity incentive plans and employee stock purchase plan, including additional registration statements on Form S-8 to register additional shares of Common Stock pursuant to the “evergreen” provisions thereunder. Shares registered under these registration statements on Form S-8 will be available for sale in the public market, subject to vesting arrangements and exercise of options, and the restrictions of Rule 144 in the case of our affiliates. Sales of a substantial number of shares of our Common Stock in the public market could occur at any time.

Table of Contents

On May 29, 2025, we filed an automatic shelf registration statement on Form S-3ASR with the SEC, which enables us to offer for sale, from time to time, an unspecified amount of Common Stock, preferred stock, debt securities and warrants. The Form S-3ASR became automatically effective upon filing and is valid for three years.

We are currently an “emerging growth company” within the meaning of the Securities Act, and to the extent we have taken advantage of certain exemptions from disclosure requirements available to emerging growth companies, this could make our securities less attractive to investors and may make it more difficult to compare our performance with other public companies.

We are currently an “emerging growth company” within the meaning of the Securities Act, as modified by the JOBS Act, and we may take advantage of certain exemptions from various reporting requirements that are applicable to other public companies that are not “emerging growth companies” including, but not limited to, not being required to comply with the auditor attestation requirements of Section 404 of the Sarbanes-Oxley Act, reduced disclosure obligations regarding executive compensation in our periodic reports and proxy statements, and exemptions from the requirements of holding a nonbinding advisory vote on executive compensation and shareholder approval of any golden parachute payments not previously approved.

Further, Section 102(b)(1) of the JOBS Act provides emerging growth companies with delayed reporting requirements with respect to new or revised financial accounting standards. The JOBS Act provides that a company can elect to opt out of the extended transition period and comply with the requirements that apply to non-emerging growth companies, but any such an election to opt out is irrevocable.

We have elected not to opt out of such extended transition period, which means that when a standard is issued or revised and it has different application dates for public or private companies, we, as an emerging growth company, can adopt the new or revised standard at the time private companies adopt the new or revised standard. This may make comparison of our financial statements with another public company which is neither an emerging growth company nor an emerging growth company which has opted out of using the extended transition period difficult or impossible because of the potential differences in accounting standards used.

Under the current rules of the SEC, we will no longer be eligible to take advantage of the scaled disclosures available to smaller reporting companies beginning with our Quarterly Report on Form 10-Q for the first quarter of 2026. We expect that the loss of the ability to take advantage of scaled disclosures will result in increased legal, accounting and financial compliance costs.

Delaware law and our Certificate of Incorporation and Bylaws contain certain provisions, including anti-takeover provisions, which limit the ability of stockholders to take certain actions and could delay or discourage takeover attempts that stockholders may consider favorable.

The Certificate of Incorporation of the Company (the “Certificate of Incorporation”) and the bylaws of the Company (the “Bylaws”), as well as the General Corporation Law of the State of Delaware (“DGCL”), contain provisions that could have the effect of rendering more difficult, delaying, or preventing an acquisition deemed undesirable by the Board and therefore depress the trading price of our Common Stock. These provisions could also make it difficult for stockholders to take certain actions, including electing directors who are not nominated by the current members of the Board or taking other corporate actions, including effecting changes in our management. Among other things, the Certificate of Incorporation and Bylaws include provisions regarding:

providing for a classified board of directors with staggered, three-year terms;
the ability of the Board to issue up to 10,000,000 shares of preferred stock, including “blank check” preferred stock, with any rights, preferences and privileges as they may designate, including the right to approve an acquisition or other change of control;
provide that the authorized number of directors may be changed only by the resolution of the Board;
provide that, subject to the rights of the holders of any series of preferred stock, any individual director or directors may be removed only with cause by the affirmative vote of the holders of at least 66 2/3% of the voting power of all of the then-outstanding shares of our capital stock entitled to vote generally in the election of directors, voting together as a single class;
provide that all vacancies, including newly created directorships, may, except as otherwise required by law, be filled by the affirmative vote of a majority of directors then in office, even if less than a quorum;
require that any action to be taken by our stockholders must be affected at a duly called annual or special meeting of stockholders and not be taken by written consent or electronic transmission;
provide that stockholders seeking to present proposals before a meeting of stockholders or to nominate candidates for election as directors at a meeting of stockholders must provide advance notice in writing, and also specify requirements as to the form and content of a stockholder’s notice;

45

Table of Contents

provide that special meetings of our stockholders may be called by the chairperson of the Board, the chief executive officer or by the Board pursuant to a resolution adopted by a majority of the total number of authorized directors; and
not provide for cumulative voting rights, therefore allowing the holders of a majority of the shares of Common Stock entitled to vote in any election of directors to elect all of the directors standing for election, if they should so choose.

These provisions, alone or together, could delay or prevent hostile takeovers and changes in control or changes in the Board or management.

The Certificate of Incorporation designates the Court of Chancery of the State of Delaware or the United States federal district courts as the sole and exclusive forum for substantially all disputes between us and our stockholders, which could limit our stockholders’ ability to obtain a favorable judicial forum for disputes with us or our directors, officers, stockholders, employees or agents.

The Certificate of Incorporation provides that, unless we consent in writing to the selection of an alternative forum, the Court of Chancery of the State of Delaware shall be the sole and exclusive forum for state law claims for a list of enumerated actions, subject to certain exceptions, in which case the United States federal district courts will be the sole and exclusive forum for resolving any action asserting a claim arising under the Securities Act.

Section 22 of the Securities Act creates concurrent jurisdiction for federal and state courts over all suits brought to enforce any duty or liability created by the Securities Act or the rules or regulations thereunder. Accordingly, both state and federal courts have jurisdiction to entertain such Securities Act claims.

To prevent having to litigate claims in multiple jurisdictions and the threat of inconsistent or contrary rulings by different courts, among other considerations, the Certificate of Incorporation provides that, unless we consent in writing to the selection of an alternative forum, United States federal district courts shall be the exclusive forum for the resolution of any complaint asserting a cause of action arising under the Securities Act. There is uncertainty as to whether a court would enforce the forum provision with respect to claims under the federal securities laws.

This choice of forum provision in the Certificate of Incorporation may limit a stockholder’s ability to bring a claim in a judicial forum that it finds favorable for disputes with us or any of our directors, officers, or other employees, which may discourage lawsuits with respect to such claims.

There is uncertainty as to whether a court would enforce such provisions, and the enforceability of similar choice of forum provisions in other companies’ charter documents has been challenged in legal proceedings. It is possible that a court could find these types of provisions to be inapplicable or unenforceable, and if a court were to find the choice of forum provision contained in the Certificate of Incorporation to be inapplicable or unenforceable in an action, we may incur additional costs associated with resolving such action in other jurisdictions, which could harm our business, results of operations and financial condition.

Our Public Warrants and Private Warrants are accounted for as liabilities and the changes in value of these warrants could have a material effect on our financial results.

We are subject to complex securities laws and regulations and accounting principles and interpretations. The preparation of our financial statements requires us to interpret accounting principles and guidance and to make estimates and judgments that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the financial statements, as well as the reported expenses incurred during the reporting periods.

We base our interpretations, estimates and judgments on our historical experience and on various other factors that we believe are reasonable under the circumstances, the results of which form the basis for the preparation of our financial statements. GAAP presentation is subject to interpretation by the SEC, the Financial Accounting Standards Board and various other bodies formed to interpret and create appropriate accounting principles and guidance. If one of these bodies disagrees with our accounting recognition, measurement or disclosure or any of our accounting interpretations, estimates or assumptions, it may have a significant effect on our reported results and may retroactively affect previously reported results.

On April 12, 2021, the Acting Director of the Division of Corporation Finance and Acting Chief Accountant of the SEC together issued a statement regarding the accounting and reporting considerations for warrants issued by special purpose acquisition companies entitled “Staff Statement on Accounting and Reporting Considerations for Warrants Issued by Special Purpose Acquisition Companies (the “SEC Statement”).

46

Table of Contents

Specifically, the SEC Statement focused on certain settlement terms and provisions related to certain tender offers following a business combination, which terms are similar to those contained in the warrant agreement governing our warrants. As a result of the SEC Statement, we reevaluated the accounting treatment of our Public Warrants and Private Warrants and determined to classify the warrants as derivative liabilities measured at fair value, with changes in fair value each period reported in our net loss in the statement of operations.

As a result, included in our balance sheets as of December 31, 2025 and 2024 contained in this Annual Report on Form 10-K are derivative liabilities related to embedded features contained within our warrants. Accounting Standards Codification 815, Derivatives and Hedging (“ASC 815”) provides for the remeasurement of the fair value of such derivatives at each balance sheet date, with a resulting non-cash gain or loss related to the change in the fair value being recognized in our net loss in the statements of operations. As a result of the recurring fair value measurements, our financial statements and results of operations may fluctuate quarterly, based on factors which are outside of our control.

Due to the recurring fair value measurements, we expect that we will recognize non-cash gains or losses on our Public Warrants and Private Warrants each reporting period until such time as the warrants are exercised or expire, and that the amount of such gains or losses could be material. The impact of changes in fair value on earnings may have an adverse effect on the market price of our securities.

No assurance can be given that additional guidance or new regulations or accounting principles and interpretations will not be released that would require a restatement of our financial statements with respect to treatment of the warrants. Any such restatement of our financial results could cause adverse effects.

Our warrants are exercisable for Common Stock, the exercise of which has increased and will continue to increase the number of shares eligible for future resale in the public market and result in dilution to our stockholders.

As of December 31, 2025, the following warrants were outstanding:

Public Warrants and Private Warrants to purchase an aggregate of 8,728,586 shares of Common Stock with an exercise price of $11.50 per share.
Series C Warrants (as defined herein) to purchase 315,518 shares of Common Stock with an exercise price of $0.01.
Customer Warrant (as defined herein) to purchase an aggregate of 2,680,607 shares of Common Stock with an exercise price of $1.152 per share.

During the year ended December 31, 2025, 4,830,235 shares were issued upon the exercise of warrants. The additional shares issued resulted in dilution to the holders of Common Stock and increased the number of shares outstanding. To the extent additional warrants are exercised, stockholders may experience additional dilution. Sales of substantial shares in the public market or the fact that warrants have been and may continue to be exercised could adversely affect the market price of our Common Stock.

The terms of the Public Warrants may be amended in a manner adverse to a holder if holders of at least 50% of the then outstanding Public Warrants approve of such amendment.

The warrants were issued in registered form under a warrant agreement (the “warrant agreement”) between American Stock Transfer & Trust Company, as warrant agent, and Supernova. The warrant agreement provides that the warrants may be amended only with the approval by the holders of at least 50% of the then-outstanding Public Warrants to make any change to the warrants that adversely affects the interests of the registered holders of the Public Warrants. Although our ability to amend the terms of the Public Warrants with the consent of at least 50% of the then-outstanding Public Warrants is unlimited, examples of such amendments could be amendments to, among other things, increase the exercise price of the Public Warrants, convert the Public Warrants into cash, shorten the exercise period or decrease the number of shares of Common Stock purchasable upon exercise of a Public Warrant.

We may redeem your unexpired Public Warrants prior to their exercise at a time that is disadvantageous to the holder, thereby making such Public Warrants worthless.

We have the ability to redeem outstanding Public Warrants prior to their expiration, at a redemption price of $0.01 per warrant, provided that the last reported sales price of our Common Stock equals or exceeds $18.00 per share (as adjusted for stock splits, stock dividends, reorganizations, recapitalizations and the like) on the trading day prior to the date on which we provide notice of redemption and certain other conditions are met. In such event, holders may exercise their warrants prior to the scheduled redemption date, but only for cash, and the market price of our Common Stock may decline below both the $18.00 redemption threshold and the $11.50 exercise price following the issuance of the redemption notice.

47

Table of Contents

We also have the ability to redeem all outstanding Public Warrants, at a redemption price of $0.10 per warrant, provided that the last reported sales price of our Common Stock equals or exceeds $10.00 per share (as adjusted for stock splits, stock dividends, reorganizations, recapitalizations and the like) on the trading day prior to the date on which we provide notice of redemption. In this circumstance, holders may elect to exercise their warrants for cash on a cashless basis during the notice period. The number of shares of Common Stock issuable upon such cashless exercise ranges from 0.034 to 0.361 shares per warrant, depending on the fair market value of the Common Stock and the remaining term of the warrants, as determined pursuant to the warrant agreement. The value received upon exercise may be less than the value that could have been realized had the warrants been exercised at a later time, and the number of shares issuable is subject to a contractual cap set forth in the warrant agreement.

If the Company were to redeem the Public Warrants, this may require holders to: (i) exercise their Public Warrants and pay the exercise price therefore at a time when it may be economically disadvantageous to do so; (ii) sell their Public Warrants at the then-current market price; or (iii) accept the nominal redemption price, which is likely to be substantially less than the market value of the warrants at the time of redemption. None of the Private Warrants will be redeemable by us, subject to certain circumstances, so long as they are held by the Supernova Partners II LLC (“Supernova Sponsor”) or its permitted transferees.

The warrant agreement designates the courts of the State of New York or the United States District Court for the Southern District of New York as the sole and exclusive forum for certain types of actions and proceedings that may be initiated by holders of warrants, which could limit the ability of warrant holders to obtain a favorable judicial forum for disputes with us.

The warrant agreement provides that, subject to applicable law, the courts of the State of New York and the United States District Court for the Southern District of New York constitute the sole and exclusive forum for any action, proceeding or claim arising out of or relating to the warrant agreement, including claims under the Securities Act. We irrevocably submit to such jurisdiction and waive any objection to these courts as inconvenient or improper forums. Any purchaser or holder of Public or Private Warrants is deemed to have notice of and consented to these forum provisions.

These exclusive-forum provisions do not apply to actions brought to enforce any liability or duty created by the Exchange Act, or to any claim for which federal district courts of the United States of America are the sole and exclusive forum.

If a warrant holder initiates any action within the scope of the forum provision in any court other than the designated New York Courts, such holder will be deemed to have consented to: (x) the personal jurisdiction of the New York state and federal courts for purposes of any action to enforce the forum provision and (y) service of process through the warrant holder’s counsel in the foreign action.

This choice-of-forum provision may limit a warrant holder’s ability to bring a claim in a judicial forum it considers favorable and may discourage such lawsuits. Conversely, if a court determines that the provision is inapplicable or unenforceable with respect to certain claims, we could incur additional costs and burdens associated with litigating in multiple jurisdictions, which could materially and adversely affect our business, financial condition and results of operations and divert management’s and the Board’s time and attention.

We may be subject to securities litigation, which is expensive and could divert management attention.

The market price of our Common Stock is volatile and, in the past, companies that have experienced volatility in the market price of their stock have been subject to securities class action litigation. We may be the target of this type of litigation in the future. Securities litigation against us could result in substantial costs and divert management’s attention from other business concerns, which could seriously harm our business.

Information available in public media that is published by third parties, including blogs, articles, message boards and social and other media may include statements not attributable to the Company and may not be reliable or accurate.

We have received, and may continue to receive, a high degree of media coverage that is published or otherwise disseminated by third parties, including blogs, articles, message boards and social and other media. This includes coverage that is not attributable to statements made by our officers. Information provided by third parties may not be reliable or accurate and could materially impact the trading price of our Common Stock, which could cause stockholders to lose their investments.

ITEM 1C.          CYBERSECURITY

Risk management and strategy

We have implemented and maintain various information security processes designed to identify, assess and manage material risks from cybersecurity threats to our critical computer networks, third party hosted services, communications systems, hardware and software, and our critical data, including intellectual property and confidential information that is proprietary, strategic or competitive in nature, including information regarding our product architecture, software, algorithms, and applications (“Information Systems and Data”).

Our information security function is supported by members of our legal team and a third-party service provider, which helps identify, assess and manage the Company’s cybersecurity threats and risks, including through the use of the Company’s risk register. This team identifies and assesses risks from cybersecurity threats by monitoring and evaluating our threat environment and the Company’s risk profile using various methods including, for example: manual and automated tools; subscribing to and analyzing reports and services that identify cybersecurity threats; conducting scans of our threat environment; evaluating threats reported to us; conducting vulnerability assessments to identify vulnerabilities; and analyzing external threat intelligence feeds.

Depending on the environment, product, or system, we implement and maintain various technical, physical, and organizational measures, processes, standards and policies designed to manage and mitigate material risks from cybersecurity threats to our Information Systems and Data, including, for example: performing risk analyses, establishing an incident response policy, having vulnerability management processes, and implementing certain security certificates for certain functions of our business; encrypting certain data, using network security controls; segregating data; maintaining access and physical security controls; managing, tracking, and disposing of assets; and monitoring our systems. In addition, we may refer to and perform assessments against the Center for Internet Security’s Critical Security Controls to help inform our cybersecurity program, as well as perform assessments such as penetration tests.

Our assessment and management of material risks from cybersecurity threats are integrated into the Company’s overall risk management processes. For example, (1) cybersecurity risk is addressed as a component of the Company’s enterprise risk management program and identified in the Company’s risk register; (2) our information security function works with management, including our Chief Technology Officer (“CTO”), to prioritize our risk management processes and mitigate cybersecurity threats that could more likely lead to a material impact to our business; (3) our senior management/committee evaluates material risks from cybersecurity threats against our overall business objectives and on a quarterly basis reports to the audit committee of the board of directors, which oversees our cybersecurity risk as part of our overall enterprise risk.

We use third-party service providers to assist us from time to time to identify, assess, and manage material risks from cybersecurity threats, including for example: professional service firms; threat intelligence service providers; cybersecurity consultants; and cybersecurity software and managed cybersecurity service providers. We use third-party service providers to perform a variety of functions throughout our business, such as application providers and public cloud providers, as well as various third-party suppliers that support our manufacturing and development processes. We use certain vendor management processes to manage cybersecurity risks associated with our use of these providers, which includes reviewing the written information security programs of certain of our vendors. Depending on the nature of the services provided, the sensitivity of the Information Systems and Data at issue, and the identity of the provider, our vendor management process may involve different levels of assessment designed to help identify cybersecurity risks associated with a provider and impose contractual obligations related to cybersecurity on the provider. This can extend to contingent workers as well, who are required to complete background investigations and agree to adhere to policies, including for privacy and cybersecurity.

Governance

Our board of directors addresses the Company’s cybersecurity risk management as part of its general oversight function. The board of directors’ audit committee is responsible for overseeing Company’s cybersecurity risk management processes, including oversight and mitigation of risks from cybersecurity threats.

Our cybersecurity risk assessment and management processes are implemented and maintained by our legal team along with third-party service providers in coordination with the CTO. The CTO is responsible for hiring appropriate personnel, helping to integrate cybersecurity risk considerations into the Company’s overall risk management strategy, and communicating key priorities to relevant personnel.

Overview

We build quantum computers and the superconducting quantum processors that power them. We believe quantum computing represents one of the most transformative emerging capabilities in the world today. By leveraging quantum mechanics, we believe our quantum computers process information in fundamentally new, more powerful ways than classical computers. When scaled, it is anticipated that these systems will be poised to solve problems of staggering computational complexity at unprecedented speed.

With the goal of unlocking this opportunity, we have developed the world’s first multi-chip quantum processor for scalable quantum computing systems. We believe that this patented and patent pending, modular chip architecture is the building block for new generations of quantum processors that we expect to achieve a clear advantage over classical computers. Our long-term business model centers on revenue generated from sales of quantum processing units (“QPUs”) and quantum computing systems and providing access to quantum computing systems via the cloud in the form of Quantum Computing as a Service (“QCaaS’). However, the substantial majority of our current revenues are derived from development contracts, and we anticipate this market opportunity will continue to represent an important source of revenue for at least the next several years as we work to ramp up sales of QPUs, quantum computing systems and QCaaS. Additionally, we are working to further develop a revenue stream and forging important customer relationships by entering into technology development contracts with various partners.

We are a vertically integrated company. We operate Fab-1, a wafer fabrication facility dedicated to prototyping and producing our quantum processors. Through Fab-1, we own the means of production of our breakthrough multi-chip quantum processor technology. We leverage our chips through a full-stack product development approach, from quantum chip design and manufacturing through cloud delivery. We believe this full-stack development approach offers both the fastest and lowest risk path to building commercially valuable quantum computers. We have been generating revenue since 2018 through partnerships with government agencies and commercial organizations; however, we have not yet generated profits. We have incurred significant operating losses since inception. Our net losses were $216.2 million and $201.0 million for the years ended December 31, 2025 and December 31, 2024, respectively. We expect to continue to incur additional losses for the foreseeable future as we invest in research and development and infrastructure in line with our long-term business strategy. As of December 31, 2025, we had an accumulated deficit of $771.0 million.

Based on our forecasts, we believe that our existing cash, cash equivalents and marketable securities will be sufficient to meet our anticipated operating cash needs for at least the next twelve months based on our current business plan, and expectations and assumptions considering current macroeconomic conditions. Our operating plan may change because of factors currently unknown, and we may need to seek additional funds sooner than planned, through public or private equity or debt financing or other sources, such as strategic collaborations or other transactions. In addition, we may seek additional capital even if we believe that we have sufficient funds for current or future operating plans.

In the fourth quarter of 2024, we announced the public launch of our 84-qubit Ankaa-3 system, which featured an extensive hardware redesign. We achieved a key two-qubit gate fidelity milestone with Ankaa-3: successfully halving error rates in 2024 to achieve a 99.0% median two-qubit gate fidelity based on our internal testing. For information on gate fidelity, see “—Our Technology—Our Superconducting Quantum Processors—Fidelity.”

In the second quarter of 2025, we announced the public launch of our 36-qubit Cepheus-1-36Q system, our newest flagship quantum computer that utilizes our modular chip architecture and demonstrates our path to scaling to higher qubit count and higher performing systems. Made of four 9-qubit “chiplets,” we believe that Cepheus-1-36Q is the industry’s largest multi-chip quantum computer. As of January 2026, we achieved a 99.6% median two-qubit gate fidelity (based on internal testing) with Cepheus-1-36Q, successfully halving our error rate from our previous, single-chip 84-qubit Ankaa-3 system.

Ankaa-3 and Cepheus-1-36Q are available to our partners via the Rigetti QCS platform. Cepheus-1-36Q is intended to enable users to operate our universal CZ gates for a wide range of algorithmic research, with a median gate time of 76 nanoseconds. Our CZ gates are designed to be optimized for fast gate times while reducing coherent errors, which improves fidelity and is key for executing quantum error correction techniques. Cepheus-1-36Q features scalable chip architecture with 3D signal delivery while incorporating enhancements to key technologies, such as enhanced intermodule coupler design to enable higher performance. Leveraging our full-stack platform and in-house quantum foundry capabilities, we believe that Cepheus-1-36Q demonstrates our ability to deliver increasingly higher performance quantum computers with larger qubit counts using our proprietary chiplet-based architecture.

We are focused on continuing to improve our system performance. We recently achieved a two-qubit gate fidelity as high as 99.9% at 28 nanosecond gate speed on a prototype platform by using a new proprietary adiabatic CZ scheme. We continue to be at 99.9% one-qubit gate fidelity. In January 2026, we announced achievement of a median two-qubit gate fidelity (based on internal testing) of 99.7% on our 9-qubit system, 99.6% on our 36-qubit system and 99.0% on our 108-qubit system (Cepheus-1-108Q). Cepheus-1-108Q is based on twelve 9-qubit chiplets and leverages our proprietary modular chip architecture.

In 2025, we received purchase orders for two Novera systems totaling approximately $5.7 million. Both systems are upgradeable, allowing the customers to increase the system qubit count for more complex computations and research. Delivery for both systems is expected in the first half of 2026.

In January 2026, Rigetti Computing India P L, a wholly owned subsidiary of Rigetti Computing, Inc., announced that it received an $8.4 million purchase order to deliver a 108-qubit quantum computer to C-DAC. The system will be installed on-premises at C - DAC’s Bengaluru center and is expected to be deployed in the second half of 2026.

Powered by the production of our scalable multi-chip quantum processors in Fab-1 and our full-stack product development approach, we are working to develop quantum computing systems that demonstrate clear performance advantages over classical computing alternatives for multiple high-impact application areas.

2025 ATM Offering

On May 29, 2025, we entered into an Open Market Sale AgreementTM (the “Sales Agreement”) with Jefferies, LLC, with respect to an At-the-Market (“ATM”) offering program, pursuant to which we sold, from time to time at our sole discretion, shares of our common stock having an aggregate offering price of $350 million. The shares offered and sold in the ATM offering were issued pursuant to a shelf registration statement on Form S-3 and the related prospectus supplement. During the year ended December 31, 2025, we raised gross proceeds of $350 million from the sale of 30,309,780 shares of our common stock pursuant to the Sales Agreement, at a weighted average price of $11.55 per share. All of the shares were sold during our second quarter ended June 30, 2025. The net proceeds from the Sales Agreement during the year ended December 31, 2025 were $346.7 million. As of December 31, 2025, there were no remaining shares available for sale pursuant to the Sales Agreement.

Quanta Collaboration Agreement

In February 2025, our wholly-owned subsidiary entered into the Collaboration Agreement with Quanta, whereby the parties may enter into written statements of work from time to time pursuant to which Quanta will develop Covered Components listed in such statement of work that meet our specifications and requirements. “Covered Components” may include control systems, dilution refrigerators, flexible cables, and select other non-QPU components suitable for our quantum computing products. In addition, the parties have each agreed to invest at least $250 million over the next five years in the field of quantum computing (and Quanta’s investment will be towards personnel and capital expenditures for developing products and services and manufacturing capability in furtherance of our product roadmap). No equity or joint venture was formed under the Collaboration Agreement and costs incurred by us under the Collaboration Agreement, consisting of expenditures for research and development and related capital, will be accounted for in accordance with GAAP as incurred.

53

Table of Contents

Under the Collaboration Agreement, we will retain all rights, title and ownership to all QPU Technology (as defined in the Collaboration Agreement) and related intellectual property (“IP”) rights created in the course of activities specified in a statement of work under the Collaboration Agreement. Other than the QPU Technology and IP rights described above, to the extent there is any jointly created, invented or other developed technology in the course of the performance of activities specified in a statement of work under the Collaboration Agreement, the Company and Quanta will jointly own, and each party will hold a one-half undivided interest in, all such joint project technology and all newly-created or newly-arising IP rights with respect thereto.

In connection with the Collaboration Agreement, on February 27, 2025, we entered into a Securities Purchase Agreement with Quanta, pursuant to which we agreed to sell and issue to Quanta in a private placement transaction 3,020,412 shares of our Common Stock at a price per share of approximately $11.59, for an aggregate value of approximately $35.0 million. The private placement transaction, which was subject to regulatory clearance, closed on April 29, 2025.

Macroeconomic Considerations

Results of our operations have varied and may continue to vary based on the impact of changes in the domestic or global economy. Negative conditions in the general economy both in the United States and abroad, including conditions resulting from changes in gross domestic product growth, inflation, interest rates, financial and credit market fluctuations, supply chain constraints, international trade policies including tariffs and export controls, national security interests, pandemics, political turmoil, government shutdowns, natural catastrophes, warfare, and terrorist attacks in the United States or elsewhere, could negatively affect our business, including progress toward the development of quantum computing by increasing the cost of materials and components and our operating costs. It is not possible at this time to estimate the long-term impact that these and related events could have on our business, as the impact will depend on future developments, which are highly uncertain and cannot be predicted. If these conditions persist and deepen, we could experience an inability to access additional capital if needed, or our liquidity could otherwise be impacted, and the trading price of our Common Stock could decline.

For further discussion of the potential impacts of macroeconomic events on our business, financial condition, and operating results, see the section titled “Risk Factors,” including the risk factor titled Unstable or unfavorable market and economic conditions in our industry and or the global economy have had and may continue to have serious adverse consequences on our business, financial condition and share price. In the future, we may be required to record significant charges for impairment of our long-lived assets, other assets or investments.”

Key Components of Results of Operations

Revenue

We generate revenue through our development contracts, as well as from our sales of QPUs, quantum computing systems and our QCaaS offerings and other services including training and provision of quantum computing components. Development contracts are generally multi-year, non-recurring arrangements pursuant to which we provide professional services regarding collaborative research in practical applications of quantum computing to technology and business problems within the customer’s industry or organization and assists the customer in developing quantum algorithms and applications in areas of business interest.

Cost of Revenue

Cost of revenue consists primarily of all direct and indirect costs associated with sales of QPUs, quantum computing systems, QCaaS offerings and development contracts and other services, including materials, employee costs for program management and personnel associated with the delivery of goods and services to customers, and sub-contract costs for work performed by third parties. Cost of revenue also includes an allocation of facility costs, depreciation and amortization directly related to the development contracts and QCaaS offerings and other services.

Operating Expenses

Our operating expenses primarily consist of research and development, and selling, general and administrative expenses.

Research and Development

Research and development expenses include compensation, employee benefits, stock-based compensation, outside consultant fees, facility costs, depreciation and amortization, materials and components purchased for research and development. We expect research and development expenses to increase as we continue to invest in quantum computing and the superconducting quantum processors needed for quantum computers. We do not currently capitalize any research and development expenditures. Research and development costs are expensed as incurred.

54

Table of Contents

Selling, General and Administrative

Selling, general and administrative expenses include compensation, employee benefits, stock-based compensation, insurance, facility costs, professional service fees, and other general overhead costs other than those associated with research and development or sales of QPUs, quantum computing systems and providing development contracts, QCaaS offerings and other services. We expect selling, general and administrative expenses to increase as we grow our business, particularly to the extent we are able to demonstrate the usefulness of quantum computers and achieve quantum advantage, and subsequently enhance our product and service offerings, expand our customer base, and implement new marketing strategies.

Provision for Income Taxes

Income taxes are accounted for under the asset and liability method. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases and operating loss and tax credit carryforwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. A valuation allowance is recorded for deferred tax assets if it is more likely than not that some portion or all of the deferred tax assets will not be realized. We have recorded a full valuation allowance against our deferred tax assets.

Revenue

Revenue decreased by $3.7 million for the year ended December 31, 2025, when compared to the year ended December 31, 2024. The decrease was mainly due to a $1.4 million reduction in revenue from collaborative research and professional services contracts, and a $2.4 million reduction in revenue from sales of collaborative research materials and quantum computers. During the year ended December 31, 2025, there were no Novera ™ sales. During the year ended December 31, 2024, revenue from Novera sales totaled $1.6 million. Our revenue has been negatively impacted by expiration of the National Quantum Initiative Act in September 2023 and its pending reauthorization in the United States Congress.

55

Table of Contents

Our development contracts are typically, time and materials, cost-share based or fixed price milestone contracts and the timing and amounts of revenue recognized in any given period will vary significantly based on the work performed and/or satisfaction of performance obligations. The timing and delivery of sales of QPUs, quantum computing systems and QCaaS will also vary and impact revenue in any given quarterly or annual period. Revenue is expected to vary in terms of timing and size, resulting in significant fluctuations in revenue levels in future periods.

For the next few years, we expect much of our revenue to be generated from development contracts and anticipated sales of on-premises QPUs and quantum computing systems.

Cost of Revenue

Cost of revenue was relatively flat for the year ended December 31, 2025, when compared to the year ended December 31, 2024. The impact of lower revenue levels on cost of revenue was mostly offset by an unfavorable revenue mix, with more revenue and cost of revenue coming from contracts with higher costs and a lower gross margin profile.

Our cost of revenue and gross margins are impacted by the composition of our revenue and variability in the pricing and terms of our sales and development contracts. During the year ended December 31, 2025, we recognized revenue and cost of revenue from contracts to deliver 24-qubit and 36-qubit quantum computing systems, which have higher costs and a lower gross margin profile than most of our other contracts.

We expect that cost of revenue and total gross profit as a percentage of revenue will vary in future quarterly and annual periods due to changes in the composition of our revenue and variability in the pricing and terms of our sales and development contracts.

Operating Expenses

Research and Development

Research and development expenses increased by $11.6 million for the year ended December 31, 2025, when compared to the year ended December 31, 2024.

The increase in research and development expenses during the year ended December 31, 2025, when compared to the year ended December 31, 2024, was mainly due to increases in salaries, employee related costs and stock-based compensation for existing employees to remain competitive in the marketplace for talent and new hires. Salaries and employee related costs increased by $4.4 million and stock-based compensation costs increased by $3.7 million during the year ended December 31, 2025, when compared to the year ended December 31, 2024. All other research and development costs including materials, consultants and information technology increased by $3.5 million during the year ended December 31, 2025, when compared to the year ended December 31, 2024, to support our research and development efforts.

We anticipate that research and development expenditures will grow in the future as we continue to focus on our technology roadmap and goals of achieving quantum advantage and large-scale fault tolerant quantum computing. In the future, we may seek to significantly increase our capital expenditures, including to upgrade our current chip fabrication facility, and possibly invest in a new quantum chip fabrication facility, which would require a significant amount of cash for capital expenditures and increase our depreciation expense in future years.

Selling, General and Administrative

Selling, general and administrative expenses increased by $0.9 million for the year ended December 31, 2025, when compared to the year ended December 31, 2024.

The increase in selling, general and administrative expenses during the year ended December 31, 2025, when compared to the year ended December 31, 2024, was mainly due to higher costs for proxy distribution and solicitation related to our annual meeting, which was driven by the increase in the number of beneficial owners of our common stock. In addition, lower bonus expenses were offset by higher stock-based compensation expenses for existing employees and other costs.

We expect to incur additional selling, general and administrative expenses to support the growth of our business. Further, we expect selling, general and administrative expenses to increase over the longer term, particularly after we potentially achieve quantum advantage, and plan to subsequently enhance our sales and service offerings, expand our customer base, and implement new marketing strategies.

Other Income (Expense), net

Interest Expense

Interest expenses decreased by $3.2 million for the year ended December 31, 2025, when compared to the year ended December 31, 2024. The reduction in interest expense was due to the prepayment of our outstanding debt with Trinity Capital Inc. (“Trinity Capital”) in December 2024. A discussion regarding the debt prepayment is included in Note 7 to our consolidated financial statements for the year ended December 31, 2025, included elsewhere in this Annual Report on Form 10-K.

Interest Income

Interest income was $16.6 million for the year ended December 31, 2025, compared to $5.1 million for the year ended December 31, 2024. The increase in interest income during the year ended December 31, 2025 was due to an increase in the balances of our invested cash and available-for-sale investments resulting from our equity offerings during late 2024 and the year ended December 31, 2025. Fluctuations in the rates of interest earned on our investments also had an impact on interest income during the year.

Change in Fair Value of Warrant Liabilities

A discussion of the change in the fair value of the warrant liabilities is included in Note 8 to our consolidated financial statements for the year ended December 31, 2025, included elsewhere in this Annual Report on Form 10-K.

The change in fair value of warrant liabilities for the year ended December 31, 2025 was a loss of $150.6 million, compared to a loss of $90.2 million for the year ended December 31, 2024. The change in fair value for the year ended December 31, 2025 was primarily due to fluctuations in our stock price, while the change in fair value for the year ended December 31, 2024 was primarily due to fluctuations in our stock price and related share price volatility.

Change in Fair Value of Earn-Out Liabilities

A discussion of the change in the fair value of the earn-out liabilities is included in Note 9 to our consolidated financial statements for the year ended December 31, 2025, included elsewhere in this Annual Report on Form 10-K.

The change in fair value of our earn-out liabilities for the year ended December 31, 2025 was a gain of $2.5 million, compared to a loss of $43.7 million for the year ended December 31, 2024. The change in fair value for the year ended December 31, 2025 was primarily due to fluctuations in our stock price, while the change in fair value for the year ended December 31, 2024 was primarily due to fluctuations in our stock price and related share price volatility.

As of December 31, 2025, all of the earn-out liabilities had been satisfied and the remaining liability balance is zero. We do not expect these earn-out liabilities to have any impact on the consolidated financial statements in future periods.

Loss on Extinguishment of Debt

On December 9, 2024, we prepaid in full all amounts owed under our Amended Loan Agreement with Trinity Capital Inc. We prepaid an aggregate of $9.5 million in outstanding principal balance, final payment fees of $0.9 million, plus accrued interest and a prepayment premium aggregating $0.1 million. During the year ended December 31, 2024, we recorded a $0.4 million loss on the prepayment and extinguishment of the outstanding principal balance owed under the Amended Loan Agreement.

Provision for Income Taxes

We have incurred a cumulative pre-tax loss for the past three years. We expect to continue to incur losses for income tax purposes for the foreseeable future and will continue to carry a full valuation allowance for our deferred tax assets. Accordingly, we did not record a provision for income taxes for either the year ended December 31, 2025 or the year ended December 31, 2024.

On July 4, 2025, new federal tax and budget legislation, known as the “One Big Beautiful Bill Act” (“OBBA”) was signed into law. We evaluated the impact of the OBBA and determined that its provisions did not have a material impact on our consolidated financial statements.

Liquidity and Capital Resources

We have incurred net losses and negative cash flows from operations since inception. Historically, we have financed our operations primarily through the sale and issuance of Common Stock, preferred stock, warrants, convertible notes, debt and revenues. During the years ended December 31, 2025 and December 31, 2024, we incurred net losses of $216.2 million and $201.0 million, respectively. As of December 31, 2025, we had an accumulated deficit of $771.0 million, and we expect to incur additional losses for the foreseeable future.

57

We believe that our existing balances of cash, cash equivalents and available-for-sale investments will be sufficient to meet our anticipated operating cash needs for at least the next twelve months based on our current business plan, and expectations and assumptions considering current macroeconomic conditions. Our operating plan may change because of factors currently unknown, including factors described herein, and we may need to seek additional funds sooner than planned, through public or private equity or debt financings or other sources, such as strategic collaborations or other transactions. In addition, we may seek additional capital even if we believe that we have sufficient funds for current or future operating plans.

We have based these estimates on assumptions that may prove to be wrong and we could use our available capital resources sooner than we currently expect, and future capital requirements and the adequacy of available funds will depend on many factors including those described in the section titled “Risk Factors” in this Annual Report on Form 10-K.

If we are unable to raise capital when needed and on attractive terms, we would be forced to delay, reduce or eliminate our research and development programs and/or other efforts. A recession or market corrections resulting from the impact of macroeconomic conditions could materially affect our business and the value of our securities.

Our cash requirements include employee-related costs such as salaries and benefits; materials and components for research and development; working capital requirements; capital expenditures for our quantum chip fabrication facility; quantum computing refrigerators and other requirements; planned development of multiple generations of quantum processors; anticipated investments to scale our operations in the future; and strategic collaborative arrangements and investments. In the future, we may seek to significantly increase our capital expenditures, including to upgrade our chip fabrication facility, possibly invest in a new quantum chip fabrication facility and for additional quantum computing refrigerators, which would require a significant amount of cash for capital expenditures.

With respect to our longer-term future cash requirements, we will require a significant amount of cash for expenditure as we invest in ongoing research and development and business operations, including with respect to the Collaboration Agreement with Quanta, pursuant to which we are required to invest at least $250.0 million in the field of quantum computing in furtherance of our product roadmap over a five-year period that commenced on February 27, 2025.

Until such time as we can generate significant revenue from sales of QPUs and quantum computing systems, our development contracts and other services, including our QCaaS offering, we believe we will meet our cash requirements and obligations primarily through our existing cash, cash equivalents and available-for-sale investments, potential securities financings or other capital sources. To the extent that we raise additional capital through the sale of equity or convertible debt securities, the ownership interest of our stockholders will be, or could be, diluted, and the terms of these securities may include liquidation or other preferences that adversely affect the rights of our common stockholders. In addition, the likelihood that Public Warrant holders will exercise their warrants, and therefore the amount of cash proceeds that we would receive, is dependent upon the trading price of our Common Stock. If the trading price for our Common Stock is less than $11.50 per share, we believe holders of our Public Warrants will be unlikely to exercise their warrants. To the extent our warrants are exercised, additional shares of Common Stock will be issued, which will result in dilution to the holders of our Common Stock and increase the number of shares eligible for resale in the public market.

Debt financing and equity financing, if available, may involve agreements that include covenants limiting or restricting our ability to take specific actions, such as incurring additional debt, making capital expenditures or declaring dividends. If we are unable to raise additional funds through equity or debt financings when needed and on attractive terms, we may be required to delay, limit, or substantially reduce our quantum computing development efforts. Our future capital requirements and the adequacy of available funds will depend on many factors, including those described in the section titled “Risk Factors” in this Annual Report on Form 10-K.

Macroeconomic conditions, including inflation, interest rates and impacts from government policy and actions, such as international trade restrictions and policies and tariffs, may have adverse consequences, which may result in an economic recession globally or in the U.S., which could lead to a reduction in product demand, a decrease in corporate capital expenditures, prolonged unemployment, labors shortages, reduction in consumer confidence, adverse geopolitical and macroeconomic events, or any similar
negative economic condition. In addition, macroeconomic and geopolitical conditions may lead to disruptions to, and volatility and uncertainty in, the credit and financial markets in the U.S. and worldwide.

 Cash Flows Used in Operating Activities

Our cash flows from operating activities are significantly affected by our ability to achieve significant growth to offset expenditures related to research and development, and selling, general and administrative activities. Our operating cash flows are also affected by our working capital needs to support growth in personnel-related expenditures and fluctuations in accounts payable and other current assets and liabilities.

Table of Contents

Net cash used in operating activities during the year ended December 31, 2025 was $58.5 million, primarily resulting from our net loss of $216.2 million, partially offset by non-cash expenses totaling $165.5 million. Changes in operating assets and liabilities had a $7.9 million unfavorable impact on net cash used in operating activities during the year ended December 31, 2025.

Net cash used in operating activities during the year ended December 31, 2024 was $50.6 million, primarily resulting from our net loss of $201.0 million, partially offset by non-cash expenses totaling $153.4 million. Changes in operating assets and liabilities had a $3.1 million unfavorable impact on net cash used in operating activities during the year ended December 31, 2024.

Cash used in operating activities increased by $7.9 million during the year ended December 31, 2025 when compared to the year ended December 31, 2024. The $15.2 million increase in our net loss for the year ended December 31, 2025, when compared to our net loss for the year ended December 31, 2024, was primarily due to the non-cash changes in the fair value of our derivative warrant and earn-out liabilities. Non-cash expenses impacting our net loss increased by $12.1 million to $165.5 million during the year ended December 31, 2025, when compared to the year ended December 31, 2024. Operating assets and liabilities had a $4.8 million unfavorable impact on the change in cash used in operating activities during the year ended December 31, 2025, when compared to the year ended December 31, 2024, mostly due to lower accounts receivable collections and payments for prepaids and other assets.

Cash Flows Used in Investing Activities

Cash used in investing activities during the year ended December 31, 2025 totaled $403.3 million, resulting from $635.6 million of purchases of available-for-sale securities and $18.7 million of purchases of property and equipment, partially offset by $251.0 million of maturities of available-for-sale securities.

Cash used in investing activities during the year ended December 31 2024 totaled $78.4 million, resulting from $224.8 million of purchases of available-for-sale securities and $11.1 million of purchases of property and equipment, offset in part by $157.5 million of maturities of available-for-sale securities.

Investments in property and equipment relate primarily to process computing equipment, quantum computing refrigerators, and development tools for our chip fabrication facility. 

Net cash used in investing activities during the year ended December 31, 2025 increased by $324.9 million when compared to the year ended December 31, 2024, primarily due to investment of proceeds from our $350 million ATM program, resulting in higher purchases of available-for-sale securities.

Cash Flows Provided by Financing Activities

Cash provided by financing activities during the year ended December 31, 2025 totaled $439.1 million. We received net proceeds of $346.7 million from the sale of 30,309,780 shares of Common Stock pursuant to our ATM program that was completed during the year ended December 31, 2025. We received proceeds of $35.0 million from the sale of 3,020,412 shares of Common Stock from the private placement transaction with Quanta. We received proceeds of $50.0 million from the exercise of warrants, $2.0 million from the exercise of stock options and $6.3 million from tax withholdings on sell-to-cover equity award transactions. We also paid $0.9 million for offering costs.

Cash provided by financing activities during the year ended December 31, 2024 totaled $175.5 million, reflecting proceeds of $12.8 million, net of commissions, from the sale of 10.1 million shares of Common Stock to B. Riley Principal Capital II, LLC (“B. Riley”) through the Common Stock Purchase Agreement (the “Purchase Agreement”) we entered into with B. Riley on August 11, 2022, proceeds of $97.5 million, net of commissions, from the sale of 68.8 million shares of Common Stock under the At-the-Market Sales Agreement (the “Prior ATM Agreement”) we entered into with B. Riley Securities, Inc. and Needham & Company, LLC on March 15, 2024, proceeds of $96.0 million, net of commissions, from the sale of 50.0 million shares of Common Stock through a registered direct offering and proceeds of $0.6 million from the exercise of stock options and warrants.

Cash provided by financing activities increased by $263.6 million during the year ended December 31, 2025, when compared to the year ended December 31, 2024. The increase was primarily due to the $346.7 million of net proceeds we received from our $350.0 million ATM offering completed in June 2025. Other factors favorably impacting the increase in cash provided by financing activities during the year ended December 31, 2025, when compared to the year ended December 31, 2024, include proceeds from the exercise of warrants of $50.0 million, proceeds of $35.0 million from the sale of common stock to Quanta, a $12.5 million favorable change in the impact of tax withholdings on sell-to-cover equity award transactions and a $23.3 million reduction in payments of principal of notes payable due to the prepayment of our outstanding debt with Trinity Capital in December 2024. These increases were offset in part by proceeds of $206.3 million from sales of Common Stock during the year ended December 31, 2024.

Contractual Obligations and Contingencies

See Note 19 to our consolidated financial statements located in “Part II Item 8 – Financial Statements and Supplementary Data. Notes to Consolidated Financial Statements” in this Annual Report on Form 10-K for a description of our contractual obligations and contingencies.

Critical Accounting Estimates

This Management’s Discussion and Analysis of Financial Condition and Results of Operations is based on our consolidated financial statements included in this Annual Report on Form 10-K, which have been prepared in accordance with GAAP.

Preparation of these financial statements requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities. We also make estimates and assumptions that affect revenue and expenses during the reporting periods.

Our estimates are based on historical experience and on various other factors that we believe are reasonable under the circumstances. The results of these estimates form the basis for making judgments about the carrying value of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates.

While our significant accounting policies are described in the Notes to our consolidated financial statements for the year ended December 31, 2025, included elsewhere in this Annual Report on Form 10-K, we believe the following critical accounting estimates are most important to understanding and evaluating our reported financial results.

Public Warrants and Private Warrants

As of December 31, 2025, there were 8,728,586 Private and Public Warrants outstanding, consisting of 1,000,674 Private Warrants and 7,727,912 Public Warrants. Each whole warrant entitles the holder to purchase one share of our Common Stock at a price of $11.50 per share, subject to adjustments and will expire on March 2, 2027 at 5:00 p.m., New York City time or earlier upon redemption or liquidation.

The Private Warrants do not meet the derivative scope exception and are accounted for as derivative liabilities. Specifically, the Private Warrants contain provisions that cause the settlement amounts to be dependent upon the characteristics of the holder of the warrant which is not an input into the pricing of a fixed-for-fixed option on equity shares. Therefore, the Private Warrants are not considered indexed to our stock and should be classified as a liability.

Since the Private Warrants meet the definition of a derivative, we recorded the Private Warrants as liabilities in the consolidated balance sheet at fair value upon the closing of the Business Combination (described in Note 2 to our consolidated financial statements included elsewhere in this Annual Report on Form 10-K), with subsequent changes in the fair value recognized in the consolidated statements of operations at each reporting date. The fair value of the Private Warrants was measured using the Black-Scholes option-pricing model at each measurement date.

The Public Warrants also fail to meet the indexation guidance in ASC 815 and are accounted for as liabilities as the Public Warrants include a provision whereby in a scenario in which there is not an effective registration statement, the warrant holders have a cap, 0.361 shares of Common Stock per warrant (subject to adjustment), on the issuable number of shares in a cashless exercise. Subsequent to the separate listing and trading of the Public Warrants, the fair value of the Public Warrants has been measured based on the observable listed prices for such warrants.

There are a number of variables impacting the Black-Scholes option-pricing model used to value the derivative liability for the Private Warrants. The most impactful variable is the price of our Common Stock. The derivative liability for the Private Warrants will correspondingly increase or decrease as the price of our Common Stock increases or decreases.

As of December 31, 2025 and December 31, 2024 the fair value of the derivative liability for the Private Warrants was $16.8 million and $22.8 million, respectively, with the change in the fair value of the derivative warrant liabilities recorded in the consolidated statements of operations each reporting period.

As of December 31, 2025 and December 31, 2024 the fair value of the derivative liability for the Public Warrants was $85.8 million and $70.3 million, respectively, with the change in the fair value of the derivative warrant liabilities recorded in the consolidated statements of operations each reporting period.

Earn-Out Liabilities

On March 2, 2022 (the “Closing Date”), a merger transaction between Rigetti Holdings, Inc. (“Legacy Rigetti”) and Supernova Partners Acquisition Company II, Ltd. (“SNII”) was completed (the “Business Combination”). Upon the closing of the Business Combination, SNII, Supernova Partners II, LLC and SNII’s directors and officers (collectively the “Sponsor Holders”) subjected certain shares of our Common Stock that they own ( the “Sponsor Vesting Shares”) to forfeiture and vesting if thresholds related to the weighted average price of our Common Stock were not met for the duration of various specified consecutive day trading periods during the five-year period following the Closing Date (the “Earn-out Triggering Events”). Any such shares held by the Sponsor Holders that remain unvested after the fifth anniversary of the closing of the Business Combination were to be forfeited.

A total of 2,479,000 shares of our Common Stock held by the Sponsor Holders had a $12.50 per share price threshold for vesting (such shares, the “Promote Sponsor Vesting Shares”) and a total of 580,273 shares of our Common Stock held by the Sponsor Holders had a $15.00 per share price threshold for vesting (such shares, the “Sponsor Redemption Based Vesting Shares,” and, collectively with the Promote Sponsor Vesting Shares, the “Sponsor Vesting Shares”).

The Sponsor Vesting Shares were accounted for as liability classified instruments because the Earn-Out Triggering Events that determined the number of Sponsor Vesting Shares to be earned back by the Sponsor Holders include outcomes that were not solely indexed to our Common Stock. The aggregate fair value of the Sponsor Vesting Shares at the time of the closing of the Business Combination was estimated using a Monte Carlo simulation model and was determined to be $20.4 million. There were a number of variables impacting the Monte Carlo simulation model used to value the earn-out liabilities, with the most impactful being the price of our Common Stock. Prior to vesting, the earn-out liabilities were adjusted to fair value each reporting period using the Monte Carlo simulation model.

During the year ended December 31, 2025, the Earn-out Triggering Events for each of the Sponsor Redemption-Based Vesting Shares and the Promote Sponsor Vesting Shares were satisfied, and the underlying earn-out liabilities were adjusted to fair value using the closing market price of our Common Stock on their respective vesting dates. The earn-out liability for the Sponsor Redemption-Based Vesting Shares as of their August 14, 2025, vesting date was $10.4 million. The earn-out liability for the Promote Sponsor Vesting Shares as of their February 6, 2025, vesting date was $32.9 million. The earn-out liabilities for the Sponsor Redemption-Based Vesting Shares and the Promote Sponsor Vesting Shares were recorded to additional paid-in capital on their respective vesting dates.

As of December 31, 2025, all of the Earn-out Triggering Events related to the Sponsor Vesting Shares had occurred, the Sponsor Vesting Shares were fully vested and the remaining liability balance was zero. As of December 31, 2024, the fair value of the earn-out liabilities was $45.9 million, with the change in the fair value of the earn-out liabilities recorded in the consolidated statements of operations.

Revenue Recognition

Revenue consists primarily of our contracts for the sale of QPUs, quantum computing systems, custom computing components, access to Rigetti quantum computing systems, collaborative research services and professional services.

Revenue related to the sale of QPUs, quantum computing systems, including Novera™ and Cepheus, and custom quantum computing components is recognized at a point in time when obligations under the terms of the contract are satisfied and control is transferred to the customer, generally upon shipment for sales of QPUs and quantum computing systems, and upon customer acceptance for sales of custom quantum computing components.

Access to Rigetti quantum computing systems can be purchased as a quantum computing subscription, or on a usage basis for a specified quantity of hours. Revenue related to subscription-based access to Rigetti quantum computing systems (i.e., quantum computing subscriptions) is recognized on a ratable basis over the subscription term. Revenue related to usage-based access to Rigetti quantum computing systems is recognized over time as the systems are accessed using an output method based on compute credit hours expended.

Revenue related to collaborative research services and professional services is recognized over time, based on hours or costs incurred. For fixed price milestone-based contracts, if a milestone is deemed probable of being met, revenue is recognized over the time period the performance obligation is satisfied using an input measure based on actual labor hours or costs incurred. For those milestones not deemed probable of being met, revenue is recognized upon satisfaction of the performance obligation. Revenue related to cost-share contracts is recognized using an input based on actual reimbursable costs incurred.

Our fixed fee development contracts vary in term from one to five years, with the majority of such contracts having a term of six months to two years. When establishing the pricing for our fixed fee arrangements, we determine the pricing based on estimated costs to complete and expected margins taking into account the scope of work outlined within the contract being evaluated and our historical experience with similar services and contracts.

61

Table of Contents

Actual costs incurred over the period in which these contracts are fulfilled could vary from these estimates and therefore, these estimates are subject to uncertainty. On a quarterly basis, management reviews the progress with respect to each contract and its related milestones and evaluates whether any changes in estimates exist. As a result of the quarterly reviews, revisions in the estimated effort to complete the contract are reflected in the period in which the change is identified.

These revisions may impact the overall progress related to transfer of control and therefore result in either increases or decreases in revenues as well as increases or decreases in fulfillment costs and contract margins. In accordance with ASC No. 250, Accounting Changes and Error Corrections, any changes in estimates are reflected in our consolidated statements of operations in the period in which the circumstances that give rise to the revision become known to management. To date, we have not experienced any changes in estimates that have had a material impact on our results from operations or financial position.

When our contracts with customers contain multiple performance obligations, the transaction price is allocated on a relative standalone selling price basis to each performance obligation. We typically determine standalone selling price based on observable selling prices of our products and services. In instances where standalone selling price is not directly observable, standalone selling price is determined using information that may include market conditions and other observable inputs. Stand-alone selling price is typically established as a range. In situations in which the stated contract price for a performance obligation is outside of the applicable standalone selling price range and has a different pattern of transfer to the customer than the other performance obligations in the contract, we will reallocate the total transaction price to each performance obligation based on the relative standalone selling price of each.

The transaction price is the amount of consideration to which we expect to be entitled in exchange for transferring goods and services to the customer. Revenue is recorded based on the transaction price, which includes fixed consideration and estimates of variable consideration. The amount of variable consideration included in the transaction price is constrained and is included only to the extent it is probable that a significant reversal of cumulative revenue recognized will not occur when the uncertainty associated with the variable consideration is subsequently resolved.

Our contracts with customers may include renewal, upgrade rights or other options at fixed prices. Determining whether such options are considered distinct performance obligations that provide the customer with a material right and therefore should be accounted for separately requires significant judgment. Judgment is required to determine the standalone selling price for each renewal option to determine whether the renewal pricing is reflective of standalone selling price or is reflective of a discount that would provide the customer with a material right. Based on our assessment of standalone selling prices, we determined that certain of the Company’s sales contracts for the Novera QPU contain material upgrade rights which have been deferred.

Recently Issued Accounting Pronouncements

A description of recently issued accounting pronouncements that may potentially impact our financial position and results of operations is disclosed in Note 2 of our consolidated financial statements for the year ended December 31, 2025 included elsewhere in this Annual Report on Form 10-K.

Emerging Growth Company and Smaller Reporting Company Status

In April 2012, the JOBS Act was enacted. Section 107 of the JOBS Act provides that an “emerging growth company” (“EGC”) may take advantage of the extended transition period provided in Section 7(a)(2)(B) of the Securities Act for complying with new or revised accounting standards. Therefore, an emerging growth company can delay the adoption of certain accounting standards until those standards would otherwise apply to private companies. Following the Business Combination, we still qualify as an emerging growth company and plan to take advantage of the extended transition period that emerging growth company status permits. During the extended transition period, it may be difficult or impossible to compare our financial results with the financial results of another public company that complies with public company effective dates for accounting standard updates because of the potential differences in accounting standards used.

We will remain an EGC under the JOBS Act until the earliest of (a) December 31, 2026, (b) the last date of our fiscal year in which we have total annual gross revenue of at least $1.235 billion, (c) the date on which we are deemed to be a “large accelerated filer” under the rules of the SEC or (d) the date on which we have issued more than $1.0 billion in non-convertible debt securities during the previous three years. Under the current rules of the SEC, we will no longer be eligible to take advantage of the scaled disclosures available to smaller reporting companies beginning with our Quarterly Report on Form 10-Q for the first quarter of 2026.

ITEM 7A.             Quantitative and Qualitative Disclosures About Market Risk.

We are utilizing scaled disclosures for a smaller reporting company as defined by Rule12b-2 of the Exchange Act and are not required to provide the information required under this item.

Opinion on the Consolidated Financial Statements

We have audited the accompanying consolidated balance sheets of Rigetti Computing, Inc. (the “Company”) as of December 31, 2025 and 2024, the related consolidated statements of operations, comprehensive loss, stockholders’ equity, and cash flows for each of the years then ended, and the related notes (collectively referred to as the “consolidated financial statements”). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Company at December 31, 2025 and 2024, and the results of its operations and its cash flows for the years then ended, in conformity with accounting principles generally accepted in the United States of America.

Basis for Opinion

These consolidated financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on the Company’s consolidated financial statements based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud. The Company is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. As part of our audits we are required to obtain an understanding of internal control over financial reporting but not for the purpose of expressing an opinion on the effectiveness of the Company’s internal control over financial reporting. Accordingly, we express no such opinion.

Our audits included performing procedures to assess the risks of material misstatement of the consolidated financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the consolidated financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements. We believe that our audits provide a reasonable basis for our opinion.

RIGETTI COMPUTING, INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(1) Description of Business

Rigetti Computing, Inc. and its subsidiaries (collectively, the “Company” or “Rigetti”), builds quantum computers and the superconducting quantum processors that power them. The Company sells 9-qubit to 108-qubit quantum computing systems under the Novera™ and Cepheus trade names. Through the Rigetti Quantum Cloud Services (QCS®) platform, the Company’s machines can be integrated into any public, private or hybrid cloud.

The Company is located and headquartered in Berkeley, California. The Company also operates in Fremont, California; London, United Kingdom; Adelaide, Australia; British Columbia, Canada and Mumbai, India. The Company’s revenue is derived primarily from operations in the United States and the United Kingdom.

(2) Summary of Significant Accounting Policies

Basis of Presentation

On March 2, 2022 (the “Closing Date”), a merger transaction between Rigetti Holdings, Inc. (“Legacy Rigetti”) and Supernova Partners Acquisition Company II, Ltd. (“SNII”) was completed (the “Business Combination”). In connection with the closing of the Business Combination, the Company changed its name to Rigetti Computing, Inc. and all of SNII Class A ordinary shares and SNII Class B ordinary shares automatically converted into shares of Common Stock, par value $0.0001, of the Company (the “Common Stock”) on a one-for-one basis. The SNII Public Warrants and the SNII Private Warrants became warrants for Common Stock. The Company’s Common Stock and Public Warrants trade on the Nasdaq Capital Market under the ticker symbols “RGTI” and “RGTIW,” respectively.

The Company determined that Legacy Rigetti was the accounting acquirer in the Business Combination based on an analysis of the criteria outlined in Accounting Standards Codification (ASC) 805, Business Combination.

Accordingly, for accounting purposes, the Business Combination was treated as the equivalent of Legacy Rigetti issuing stock for the net assets of SNII, accompanied by a recapitalization. The primary asset acquired from SNII was cash that was assumed at historical costs. Separately, the Company also assumed warrants that were deemed to be derivatives and meet liability classification subject to fair value adjustment measurements upon closing of the Business Combination. No goodwill or other intangible assets were recorded because of the Business Combination. While SNII was the legal acquirer in the Business Combination because Legacy Rigetti was deemed the accounting acquirer, the historical financial statements of Legacy Rigetti became the historical financial statements of the combined company, upon the consummation of the Business Combination.

Risks and Uncertainties

The Company is subject to a number of risks similar to those of other companies of similar size in its industry, including, but not limited to, the need for successful development of products, the potential need for additional capital (or financing) in the future, competition from substitute products and services from larger companies, protection of proprietary technology, patent litigation, dependence on key individuals, and risks associated with changes in information technology.

Based on the Company’s forecasts, the Company believes that its existing cash and cash equivalents and available for sale investments will be sufficient to meet its anticipated operating cash needs for at least the next twelve months from the issuance date of these financial statements based on the Company’s current business plan and expectations and assumptions considering current macroeconomic conditions.

Macroeconomic Conditions 

Results of the Company’s operations have varied and may continue to vary based in part on the impact of changes in the domestic or global economy. Negative conditions in the general economy both in the United States and abroad, including conditions resulting from changes in gross domestic product growth, inflation, financial and credit market fluctuations, supply chain constraints, international trade policies including tariffs and export controls, national security interests, pandemics, political turmoil, government shutdowns, natural catastrophes, warfare, and terrorist attacks in the United States or elsewhere, could negatively affect the Company’s business, including progress toward the development of quantum computing by increasing the cost of materials and components and our operating costs. It is not possible at this time to estimate the long-term impact that these and related events could have on the Company’s business, as the impact will depend on future developments, which are highly uncertain and cannot be predicted.

70

Table of Contents

Principles of Consolidation 

The accompanying consolidated financial statements of the Company and its subsidiaries have been prepared in accordance with accounting principles generally accepted in the United States (“GAAP”) and applicable rules and regulations of the U.S. Securities and Exchange Commission (“SEC”). The consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. All intercompany transactions and balances have been eliminated in consolidation.

Emerging Growth Company 

Following the Business Combination, the Company qualifies as an emerging growth company (‘‘EGC’’) as defined in the Jumpstart our Business Startups (‘‘JOBS’’) Act. The JOBS Act permits companies with EGC status to take advantage of an extended transition period to comply with new or revised accounting standards, delaying the adoption of these accounting standards until they apply to private companies. The Company intends to use this extended transition period to enable it to comply with new or revised accounting standards that have different effective dates for public and private companies until the earlier of the date the Company (i) is no longer an EGC or (ii) affirmatively and irrevocably opts out of the extended transition period provided in the JOBS Act. As a result, the consolidated financial statements may not be comparable to companies that comply with the new or revised accounting standards as of public company effective dates.

Use of Estimates 

The preparation of the consolidated financial statements in accordance with U.S. GAAP requires management to make estimates and assumptions that affect reported amounts and disclosures. These estimates and assumptions affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements, as well as reported amounts of revenues and expenses during the reporting period. Such management estimates include, but are not limited to, the fair value of share-based awards, the fair value of derivative warrant liabilities, the fair value of Sponsor Vesting Shares issued in connection with the Business Combination, accrued liabilities and contingencies, depreciation and amortization periods, revenue recognition and accounting for income taxes. Management evaluates its estimates and assumptions on an ongoing basis using historical experience and other factors, including the current economic environment and adjusts when facts and circumstances dictate. These estimates are based on information available as of the date of the consolidated financial statements; therefore, actual results could differ from those estimates.

Segments

Our Chief Operating Decision Maker (“CODM”), the Chief Executive Officer, manages the Company’s business activities as a single operating and reportable segment at the consolidated level. Accordingly, our CODM uses consolidated net loss to measure segment profit or loss, allocate resources and assess performance. Further, the CODM reviews and utilizes natural expenses such as employee wages and benefits at a consolidated level to manage the Company’s operations and strategic growth initiatives. Other segment items include interest income, changes in fair value of derivative warrant liabilities and earnout liabilities and other operational expenses which are reflected in the consolidated statements of operations.

Foreign Currency Translation and Transactions

The Company’s reporting currency is the US dollar. The functional currencies of the Company’s foreign subsidiaries are their respective local currencies (UK pounds sterling, Australian dollar, Canadian dollar and Indian Rupee), which are the monetary unit of account of the principal economic environment in which the Company’s foreign subsidiaries operate. Assets and liabilities of the foreign subsidiaries are translated into US dollars at exchange rates in effect at each period end. Revenues and expenses are translated at average exchange rates in effect during the period. The resulting translation adjustments are recorded in accumulated other comprehensive income (loss) as a component of stockholders’ equity.

Foreign currency transaction gains and losses resulting from or expected to result from transactions denominated in a currency other than the functional currency are recognized in other income (expense), net in the consolidated statements of operations and have not been material for all periods presented.

Comprehensive Loss 

Comprehensive loss consists of two components including net loss and total other comprehensive income (loss) after taxes. The Company’s total other comprehensive income (loss) consists of foreign currency translation adjustments that result from consolidation of its foreign subsidiaries and unrealized gains on available-for-sale debt securities.

71

Table of Contents

Cash and Cash Equivalents

The Company considers all highly liquid investment securities with remaining maturities at the date of purchase of three months or less to be cash equivalents. Cash and cash equivalents consist of funds maintained in demand deposit accounts, money market accounts and U.S. treasury securities. Cash and cash equivalent balances, at times, may exceed federally insured limits. Cash equivalents are stated at fair value.

Investments

The Company determines the classification of its investment securities at the time of purchase. All investments in fixed income securities with remaining maturities at the date of purchase of more than three months are presently classified as available-for-sale and may be sold in response to changes in interest rates, prepayment risk or other market factors. Investments classified as available for sale are recorded at fair value in the consolidated balance sheets and are classified as short-term or long-term assets based on their maturity date and expectations regarding sales. Fair values are primarily determined using quoted market prices or valuations provided by external investment managers who obtain them from a variety of industry standard data providers.

Unrealized gains and losses on available for sale investments are included as a separate component of accumulated other comprehensive income (loss), until realized. The Company evaluates its investments to assess whether those in an unrealized loss position are other than temporarily impaired. Impairments are considered other than temporary if they are related to a deterioration in credit risk or if it is likely the Company will sell the securities before recovery of the amortized cost basis. Realized gains and losses and declines in value determined to be other than temporary are determined based on the specific identification method and are reported in other income (expense), net in the statements of operations. See Note 4 for further information regarding fair value. For purposes of identifying and measuring impairment, the policy election was made to exclude the applicable accrued interest pertaining to available-for-sale securities from both the fair value and amortized cost basis. Applicable accrued interest, net of the allowance for credit losses (if any) of $3.1 million and $0.3 million, is recorded in other current assets in the consolidated balance sheets as of December 31, 2025 and December 31, 2024, respectively

Interest income and dividends are recognized in interest income on an accrual basis. Premiums and discounts on debt securities are amortized as an adjustment to interest income over the period to maturity of the related security using the effective interest method.

Accounts Receivable 

Accounts receivable are recorded at invoice value, net of allowance for credit losses. Unbilled receivables are included in accounts receivable and include amounts that were invoiced subsequent to the period end for which revenue was recognized in advance of the right to invoice. Expected credit losses for uncollectible receivable balances consider both current conditions and reasonable and supportable forecasts of future conditions. Current conditions considered include predefined aging criteria, as well as specified events that indicate the balance due is not collectible. Reasonable and supportable forecasts used in determining the probability of future collections consider publicly available macroeconomic data and whether future credit losses are expected to differ from historical losses.

The Company is not party to any off-balance sheet arrangements that would require an allowance for credit losses. As of both December 31, 2025 and December 31, 2024, the Company does not have any allowances for credit losses.

Prepaid Expenses and Other Current Assets 

Prepaid expenses and other current assets include prepaid software, prepaid insurance, other prepaid expenses and other current assets, all of which are expected to be recognized or realized within the next twelve months.

Deferred Offering Costs 

The Company capitalizes certain legal, accounting, and other third-party fees that are directly associated with the issuance of shares under a registration statement filed with the SEC. After consummation of an issuance of shares, costs allocated to equity-classified instruments are recorded as a reduction to additional paid-in capital. The Company expenses costs allocated to liability-classified instruments.

72

Table of Contents

Property and Equipment, Net 

Property and equipment are stated at cost less accumulated depreciation and amortization. Depreciation and amortization are calculated using the straight-line method over the estimated useful lives of the assets.

Furniture and information technology hardware (IT Hardware)

3 years

Process equipment

7 years

Quantum computing fridges

3-10 years

Leasehold and other improvements

Shorter of the lease-term or estimated useful-life

Expenditures for repairs and maintenance are expensed as incurred. Upon disposition, the cost and related accumulated depreciation are removed and any resulting gain or loss is reflected in other income (expense), net in the consolidated statements of operations.

Impairment of Long-Lived Assets

Long-lived assets, which consist of property and equipment and operating lease right-of-use assets, are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of the asset (asset group) may not be recoverable. When such events or changes in circumstances occur, the Company performs an undiscounted cash flow analysis to determine if an impairment exists and, if so, an impairment loss would be recorded based on the excess of the carrying amount of the asset (asset group) over its fair value.

During each of the years ended December 31, 2025 and December 31, 2024, the Company determined there were triggering events related to expected near term losses and an undiscounted cash flow analysis was performed. Based on the results of this analysis, the Company’s long-lived assets were not impaired and no impairment charges were recorded.

Leases

The Company determines if an arrangement is or contains a lease at inception. Operating lease right-of-use assets and liabilities are recognized at the lease commencement date based on the present value of lease payments over the lease term. Lease payments consist primarily of the fixed payments under the arrangement. The Company generally uses an incremental borrowing rate estimated based on the information available at the lease commencement date to determine the present value of lease payments unless the implicit rate is readily determinable. Lease expense for lease payments is recognized on a straight-line basis over the lease term.

The Company accounts for lease and non-lease components as a single lease component for office leases. Lease and non-lease components for all other leases are generally accounted for separately. Additionally, the Company does not record leases on the balance sheet that, at the lease commencement date, have a lease term of twelve months or less. Operating leases are included in operating lease right-of-use assets, current portion of operating lease liabilities, and operating lease liabilities, less current portion in the accompanying consolidated balance sheets.

Deferred Financing Costs 

The incremental cost, including the fair value of warrants, directly associated with obtaining debt financing is capitalized as deferred financing costs upon the issuance of the debt and amortized over the term of the related debt agreement using the effective-interest method with such amortized amounts included as a component of interest expense in the consolidated statements of operations. Unamortized deferred financing costs are presented on the consolidated balance sheets as a direct deduction from the carrying amount of the related debt obligation.

Public and Private Warrants

Each whole warrant entitles the holder to purchase one share of the Company’s Common Stock at a price of $11.50 per share, subject to adjustments, and will expire on March 2, 2027 at 5:00 p.m., New York City time, or earlier upon redemption or liquidation.

The Private Warrants do not meet the derivative scope exception and are accounted for as derivative liabilities. Specifically, the Private Warrants contain provisions that cause the settlement amounts to be dependent upon the characteristics of the holder of the warrant which is not an input into the pricing of a fixed-for-fixed option on equity shares. Therefore, the Private Warrants are not considered indexed to the Company’s stock and should be classified as a liability. Since the Private Warrants meet the definition of a derivative, the Company records the Private Warrants as liabilities in the consolidated balance sheet at fair value, with subsequent changes in the fair value recognized in the consolidated statements of operations at each reporting date. The fair value of the Private Warrants are measured using the Black-Scholes option-pricing model.

73

Table of Contents

The Public Warrants also fail to meet the indexation guidance in Accounting Standards Codification (“ASC”) Topic 815, Derivatives and Hedging (“ASC 815”), and are accounted for as liabilities because they include a provision whereby if there is not an effective registration statement, the warrant holders have a cap of 0.361 shares of Common Stock per warrant (subject to adjustment), on the issuable number of shares in a cashless exercise. Subsequent to the separate listing and trading of the Public Warrants, their fair value has been measured based on the observable listed trading prices for such warrants.

See Notes 4 and 8 for further information regarding the fair value of the Public and Private Warrants.

Earn-Out Liabilities

The Sponsor subjected the Sponsor Vesting Shares to vesting conditions and forfeiture, with vesting only occurring if thresholds related to the weighted average price of the Company’s Common Stock were met for various specified consecutive day trading periods during the five-year period following the closing of the Business Combination as described in Note 9 (the “Earn-Out Triggering Events”). Any Sponsor Vesting Shares unvested after the fifth anniversary of the closing of the Business Combination were to be forfeited.

The Sponsor Vesting Shares were accounted for as liability classified instruments because the Earn-Out Triggering Events that determined the number of Sponsor Vesting Shares to be earned back by the Sponsor included outcomes that were not solely indexed to the Common Stock of the Company. The aggregate fair value of the Sponsor Vesting Shares on the Closing Date were estimated using a Monte Carlo simulation model. The earn-out liabilities were adjusted to fair value each reporting period using the Monte Carlo simulation model until such time as the Earn-Out Triggering Events were achieved and the Sponsor Vesting Shares became vested.

As of December 31, 2025, all of the Sponsor Vesting Shares were vested and the earn-out liabilities balance was zero. See Note 9 for further information regarding the earn-out liabilities.

Revenue Recognition

The Company recognizes revenue in accordance with ASC 606, Revenue from Contracts with Customers and accounts for certain contract costs in accordance with ASC 340-40, Other Assets and Deferred Costs—Contracts with Customers.

The Company recognizes revenue from contracts with customers by applying the following five-step model:

Identify the contract with a customer
Identify the performance obligations in the contract
Determine the transaction price
Allocate the transaction price to the performance obligations in the contract
Recognize revenue when (or as) performance obligations are satisfied

The Company generates revenue from sales of QPUs, quantum computing systems, custom computing components, QCaaS, development contracts and other services.

Revenue related to the sale of QPUs, quantum computing systems, including Novera™ and Cepheus, and custom quantum computing components is recognized at a point in time when obligations under the terms of the contract are satisfied and control is transferred to the customer, generally upon shipment for sales of QPUs and quantum computing systems, and upon customer acceptance for sales of custom quantum computing components.  

Access to Rigetti quantum computing systems can be purchased as a quantum computing subscription, or on a usage basis for a specified quantity of hours. Revenue related to subscription-based access to QCaaS is recognized over time as access to the systems is provided on a ratable basis over the subscription term. This time-based input measure of progress provides a faithful depiction of the transfer of the services because the benefits the customer obtains generally equals the benefit from its access to the systems throughout the subscription term. Revenue related to usage-based access to Rigetti quantum computing systems is recognized over time as the systems are accessed using an output method based on compute credit hours expended. The Company believes this output method provides a faithful depiction of the transfer of the services because the customer has purchased a specified quantity of hours of usage that diminishes each time an hour is expended and therefore each hour of access to the systems is considered a discrete delivery of underlying services in these arrangements. Development contracts are generally multi-year, non-recurring arrangements in which the Company provides professional services regarding practical applications of quantum computing to technology and business problems within the customer’s industry or organization and assists the customer in developing quantum algorithms and applications that will provide commercial value to the customer in areas of business interest. Development contracts are generally invoiced on a time and materials or cost-share basis or as fixed fee arrangements invoiced on a milestone basis.

74

Table of Contents

Revenue related to development contracts and other services is recognized over time based on hours or costs incurred The Company believes these input measures of progress provide a faithful depiction of the transfer of the services because it closely depicts the Company’s efforts or inputs to the satisfaction of the performance obligation.

When the Company’s contracts with customers contain multiple performance obligations, the transaction price is allocated on a relative standalone selling price basis to each performance obligation. The Company typically determines standalone selling price based on observable selling prices of its products and services. In instances where standalone selling price is not directly observable, standalone selling price is determined using information that may include market conditions and other observable inputs. Standalone selling price is typically established as a range. In situations in which the stated contract price for a performance obligation is outside of the applicable standalone selling price range and has a different pattern of transfer to the customer than the other performance obligations in the contract, the Company will reallocate the total transaction price to each performance obligation based on the relative standalone selling price of each.

The transaction price is the amount of consideration to which the Company expects to be entitled in exchange for transferring goods and services to the customer. Revenue is recorded based on the transaction price, which includes fixed consideration and estimates of variable consideration. The amount of variable consideration included in the transaction price is constrained and is included only to the extent it is probable that a significant reversal of cumulative revenue recognized will not occur when the uncertainty associated with the variable consideration is subsequently resolved.

The Company’s contracts with customers may include renewal or other options at fixed prices. Determining whether such options are considered distinct performance obligations that provide the customer with a material right and therefore should be accounted for separately requires significant judgment. Judgment is required to determine the standalone selling price for each renewal or other option to determine whether the renewal or other option pricing is reflective of standalone selling price or is reflective of a discount that would provide the customer with a material right. Certain of the Company’s sales contracts for the Novera QPU contain material upgrade rights which have been deferred. The timing of revenue recognition may not align with the right to invoice the customer. The Company records accounts receivable when it has the unconditional right to issue an invoice and receive payment, regardless of whether revenue has been recognized. If revenue has not yet been recognized, a contract liability (deferred revenue) is also recorded. If revenue is recognized in advance of the right to invoice, a contract asset or unbilled receivable is recorded, depending on whether the Company’s right to consideration is considered conditional or unconditional. Unbilled receivables are included within accounts receivable in the consolidated balance sheets.

In instances where the timing of revenue recognition differs from the timing of the right to invoice, the Company has determined that a significant financing component generally does not exist. The primary purpose of the Company’s invoicing terms is to provide customers with simplified and predictable ways of purchasing the products and services and not to receive financing from or provide financing to the customer. Additionally, the Company has elected the practical expedient that permits an entity not to recognize a significant financing component if the time between the transfer of a good or service and payment is one year or less.

Payment terms on invoiced amounts are typically net 30 days. The Company does not offer rights of return for its products and services in the normal course of business, and contracts generally do not include significant service-type warranties that provide any incremental service to the customer beyond providing assurance that the goods and services conform to applicable specifications or customer-specific or subjective acceptance provisions. The Company also excludes from revenue government-assessed and imposed taxes on revenue-generating activities that are invoiced to customers.

The Company has elected to apply the practical expedient to expense contract acquisition costs as incurred when the expected amortization period is one year or less.

Cost of Revenue

Cost of revenue consists of direct and indirect costs associated with providing its QCaaS offerings, sales of QPUs and custom computing components, and development contracts and other services. Cost of revenue includes employee related costs, material costs and an allocation of facility costs, depreciation and amortization associated with the delivery of goods and services to customers.

Research and Development 

Research and development costs are expensed as incurred. Research and development expenses include compensation, employee benefits, stock-based compensation, outside consultant fees, allocation of facility costs, depreciation and amortization, materials and components purchased for research and development.

Selling, General and Administrative 

Selling, general and administrative expenses include compensation, employee benefits, stock-based compensation, professional service fees, allocation of facility costs, depreciation and amortization associated with general selling and administrative overhead activities.

Income Taxes 

Income taxes are accounted for under the asset and liability method. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases and operating loss and tax credit carryforwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. A valuation allowance is recorded for deferred tax assets if it is more likely than not that some portion or all of the deferred tax assets will not be realized. As of December 31, 2025 and December 31, 2024 the Company has recorded a full valuation allowance against its deferred tax assets. The Company recognizes the effect of income tax positions only if it is more likely than not that those positions will be sustained. Recognized income tax positions are measured at the largest amount that has a greater than 50% likelihood of being realized. Changes in recognition or measurement are reflected in the period in which the change in judgment occurs. The Company records interest related to unrecognized tax benefits in interest expense and penalties in income tax expense.

Net Loss Per Share 

Basic net loss per common share is computed by dividing the net loss available to common stockholders (the numerator) by the weighted average number of common shares outstanding (the denominator) during the period. Diluted net loss per common share is computed by dividing the net loss available to common stockholders by the weighted average number of common shares and potential common shares outstanding when the impact is not antidilutive. Potential common shares from stock options, unvested restricted stock units and Common Stock warrants are computed using the treasury stock method. Contingently issuable shares are included in basic net loss per share only when there is no circumstance under which those shares would not be issued. Shares issuable for little or no cash consideration shall be considered outstanding common shares and included in the computations of basic and diluted net loss per share.

Stock-Based Compensation 

The Company accounts for share-based compensation in accordance with ASC 718, Compensation – Stock Compensation. The Company’s share-based compensation awards are all equity-classified and consist of stock options, restricted stock units (“RSU”) and restricted stock awards (“RSA”). Most stock options and RSUs have a service-based vesting condition ranging from 1 to 5 years. Some stock options and RSUs include both a market-based and service-based vesting condition. RSAs are fully vested on the date of grant. The Company occasionally issues awards that might have different vesting conditions.

Compensation expense is based on the grant-date fair value of the awards and recognized over the requisite service period using a straight-line method for awards that have a service-based vesting condition. Compensation expense for awards with a market-based vesting condition is recognized over the requisite service period regardless of whether the market condition is met, unless the underlying service requirement is not met. Compensation expense for RSAs is recognized fully on the date of grant. The Company has elected to account for forfeitures of employee stock awards as they occur. The Company intends to issue new shares for all equity based awards.

Concentrations of Credit Risk

Financial instruments that potentially subject the Company to concentrations of credit risk consist primarily of cash and cash equivalents and trade accounts receivable. The Company’s cash and cash equivalents are placed with high-credit-quality financial institutions, and at times exceed federally insured limits. To date, the Company has not experienced any credit loss relating to its cash and cash equivalents.

Fair Value Measurements 

The Company reports all financial assets and liabilities and nonfinancial assets and liabilities that are recognized or disclosed at fair value in the consolidated financial statements on a recurring basis. Valuation techniques used to measure fair value must maximize the use of observable inputs and minimize the use of unobservable inputs. The authoritative guidance establishes a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurements) and the lowest priority to measurements involving significant unobservable inputs (Level 3 measurements). The three levels of the fair value hierarchy are as follows:

Level 1—Inputs are unadjusted quoted prices in active markets for identical assets or liabilities that the Company has the ability to access at the measurement date.

76

Table of Contents

Level 2—Inputs are observable, unadjusted quoted prices in active markets for similar assets or liabilities, unadjusted quoted prices for identical or similar assets or liabilities in markets that are not active, or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the related assets or liabilities.

Level 3—Inputs are unobservable for the asset or liability.

The level in the fair value hierarchy within which a fair value measurement in its entirety falls is based on the lowest-level input that is significant to the fair value measurement in its entirety.

Recently Adopted Accounting Pronouncements

In June 2022, the Financial Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2022-03- Fair Value Measurement (Topic 820): “Fair Value Measurement of Equity Securities Subject to Contractual Sale Restrictions”. The FASB issued this update (1) to clarify the guidance in Topic 820, Fair Value Measurement, when measuring the fair value of an equity security subject to contractual restrictions that prohibit the sale of an equity security, (2) to amend a related illustrative example, and (3) to introduce new disclosure requirements for equity securities subject to contractual sale restrictions that are measured at fair value in accordance with Topic 820.  ASU 2022-03 was effective for the Company for annual periods beginning after December 15, 2024, and interim periods within those fiscal years, with early adoption permitted. The Company determined that the adoption of this standard did not have an impact on the consolidated financial statements.

In December 2023, the FASB issued ASU 2023-09, “Income Taxes – Improvements to Income Tax Disclosures” requiring enhancements and further transparency to certain income tax disclosures, most notably the tax rate reconciliation and income taxes paid. ASU 2023-09 was effective for the Company for annual periods beginning after December 15, 2024 on a prospective basis. Retrospective application was also permitted. The Company adopted this standard on a prospective basis. As a result, the adoption of this standard did not have a material impact on the consolidated financial statements.

Recently Issued Accounting Pronouncements Not Yet Adopted

In November 2024, the FASB issued ASU 2024-03, “Income Statement – Reporting Comprehensive Income – Expense Disaggregation Disclosures: Disaggregation of Income Statement Expenses,” which requires disclosure of disaggregated information about specific categories underlying certain income statement expense line items in the footnotes to the financial statements for both annual and interim periods. ASU 2024-03 is effective for the Company for annual periods beginning after December 15, 2026, and interim reporting periods within annual periods beginning after December 15, 2027. Early adoption is permitted. The Company is still evaluating the impact of this pronouncement on the consolidated financial statements.

In May 2025, the FASB issued ASU 2025-04, “Compensation – Stock Compensation (Topic 718) and Revenue from Contracts with Customers (Topic 606): Clarifications to Share-Based Consideration Payable to a Customer,” which provides clarifying guidance on the accounting for share-based consideration payable to a customer. ASU 2025-04 is effective for the Company for annual periods beginning after December 31, 2026. Early adoption is permitted using either a full retrospective or modified retrospective transition method. The Company is still evaluating the impact of this pronouncement on the consolidated financial statements.

In July 2025, the FASB issued ASU 2025-05 “Financial Statements – Credit Losses (Topic 326): Measurement of Credit Losses for Accounts Receivable and Contract Assets,” which provides practical expedients for current accounts receivable and current contract assets arising from transactions accounted for under Topic 606 (revenue from contracts with customers). ASU 2025-05 is effective for the Company for the interim and annual periods beginning after December 31, 2025. Early adoption is permitted using either a full retrospective or modified retrospective transition method. The Company does not expect the adoption of this standard to have a material impact on the consolidated financial statements.

In December 2025, the FASB issued ASU 2025-10, “Accounting for Government Grants Received by Business Entities,” to establish guidance on the recognition, measurement, and presentation of government grants received by business entities. The new guidance leverages the principles in the accounting framework for government assistance in the International Financial Reporting Standards, specifically International Accounting Standard No. 20, “Accounting for Government Grants and Disclosure of Government Assistance,” makes certain targeted improvements and modifies certain of the existing disclosure requirements in ASU 832, “Government Assistance”. ASU 2025-10 is effective for public business entities in annual periods beginning after December 31, 2028 (including interim periods within) and one year later for all other entities with early adoption in any period for which financial statements have not been issued. The guidance can be applied on a modified prospective basis, a modified retrospective basis, or a full retrospective basis. The Company is still evaluating the impact of this pronouncement on the consolidated financial statements.

(3) Investments

All investments in fixed income securities are classified as cash equivalents or available-for-sale in the consolidated balance sheets based on the underlying maturity date of each investment. Fixed income securities are recorded at their estimated fair value. The amortized cost, gross unrealized holding gains and losses included in other comprehensive income (loss) and the fair value of the fixed income securities as of December 31, 2025 and December 31, 2024, respectively, are presented in the tables below (in thousands):

The Company invests in highly rated investment grade debt securities. As of December 31, 2025, all of the Company’s available-for-sale securities have final maturities of one year or less, except for four U.S. treasury securities classified as long-term with final maturities extending through May 15, 2027. The Company reviews the individual securities that have unrealized losses on a regular basis. The Company evaluates whether it has the intention to sell any of these investments and whether it is more likely than not that it will be required to sell any of them before recovery of the amortized cost basis. The Company additionally evaluates whether the decline in fair value of the securities below their amortized cost basis is related to credit losses or other factors.

None of the Company’s available-for-sale securities were in an unrealized loss position as of December 31, 2025. With respect to its available-for-sale securities in an unrealized loss position as of December 31, 2024, the Company determined that it would not need to sell any of them prior to recovery of the amortized cost basis. The Company also determined that the unrealized losses for its available-for-sale securities as of December 31, 2024 were primarily attributable to changes in interest rates and non-credit-related factors. Accordingly, the Company determined that none of the unrealized losses were other-than-temporary, and that recognition of an impairment charge was not required as of December 31, 2024. No available-for-sale securities were sold during the years ended December 31, 2025 or December 31, 2024.

See Note 4 for additional information regarding the fair value of the Company’s investments.

As of December 31, 2025 and December 31, 2024, the Company has recorded the following financial instruments subject to fair value measurements: 1) Derivative warrant liabilities—Public Warrants and Private Warrants, 2) Money Market Funds, 3) U.S. treasury securities and 4) Earn-out liabilities.

The fair value of the Public Warrants and money market funds have been measured based on their observable listed prices, a Level 1 measurement. The fair value of the Company’s Level 2 financial assets are determined by using inputs based on quoted market prices for similar instruments. All other financial instruments are classified as Level 3 instruments as they all include unobservable inputs. The Private Warrants are measured at fair value using a Black Scholes model. The fair value of the Earn-out liabilities as of December 31, 2024 were estimated using a Monte Carlo simulation model. The Company estimated the volatility of its Private Warrants and Earn-out liabilities based on the historical volatility of the Company’s Common Stock.

As of December 31, 2025 and December 31, 2024, the Company used the historical volatility of its Common Stock for the applicable valuation models because the implied volatility of the Public Warrants was no longer meaningful due to the rapid increase in the price of the Public Warrants during the fourth quarter of 2024. There were no other changes in fair value measurement techniques during the years ended December 31, 2025 or December 31, 2024.

During the year ended December 31, 2025, the vesting conditions for the Sponsor Redemption-Based Vesting Shares and the Promote Sponsor Vesting Shares (collectively the “Sponsor Vesting Shares” as defined in Note 9 below) were satisfied, and the underlying earn-out liabilities (Refer to Note 9 for Earn-out liabilities) were adjusted to fair value using the closing market price of the Company’s Common Stock on their respective vesting dates.

79

Table of Contents

The earn-out liability for the Sponsor Redemption-Based Vesting Shares as of their August 14, 2025 vesting date was $10.4 million. The earn-out liability for the Promote Sponsor Vesting Shares as of their February 6, 2025 vesting date was $32.9 million. The earn-out liabilities for the Sponsor Redemption-Based Vesting Shares and the Promote Sponsor Vesting Shares were recorded to additional paid-in capital on their respective vesting dates. As of December 31, 2025, all of the Sponsor Vesting Shares were vested and the earn-out liabilities balance was zero.

During the years ended December 31, 2025 and December 31, 2024, the number of Private Warrants (a Level 3 measurement) converted to Public Warrants (a Level 1 measurement) were 991,428 and 1,280,732, respectively. As of the date of conversion, the favorable impact of the transfer of the Private Warrants to Public Warrants on the Company’s net loss for the years ended December 31, 2025 and December 31, 2024, was $5.8 million and $2.4 million, respectively.

There were no transfers in or out of Level 3 of the fair value hierarchy during the years ended December 31, 2025 and December 31, 2024, other than conversion of Private Warrants to Public Warrants and the vesting of the Sponsor Vesting Shares as described above.

A summary of the changes in the fair value of the Company’s Level 3 financial instruments during the years ended December 31, 2025, and December 31, 2024, respectively, is as follows (in thousands):

(7)  Financing Arrangements

Loan and Security Agreement

On June 21, 2024, (the “Amendment Date”), the Company entered into the Amended and Restated Loan and Security Agreement (the “Amended Loan Agreement”), by and between Trinity Capital Inc., as lender, and Rigetti & Co, LLC and Rigetti Intermediate LLC, as borrowers, which amended and restated in its entirety the Company’s existing loan and security agreement, dated as of March 10, 2021 (as amended from time to time, the “Existing Loan Agreement”). The outstanding principal balance of the terms loans as of the Amendment Date was $16.2 million, and the economic terms and cash flows of the outstanding term loans remained unchanged under the Amended Loan Agreement. Each term loan was to be amortized in equal monthly installments through 48 months following the disbursement date of each term loan, with interest at a rate equal to the greater of 11% or the US Prime Rate plus 7.50% per annum, payable monthly.

The Company had the right to prepay the outstanding term loans, in whole or in part, subject to a prepayment premium that remained unchanged from the Existing Loan Agreement. In addition, the Company was required to pay on the respective maturity dates, or the date of an earlier prepayment, a final payment fee equal to 2.75% of the aggregate original principal amount of the term loans, which remained consistent with the Existing Loan Agreement. The final payment fees were being accreted and amortized into interest expense using the effective interest rate method over the terms of the loans.

On December 9, 2024, the Company prepaid in full all amounts owed under the Amended Loan Agreement. The Company prepaid an aggregate of $9.5 million in outstanding principal balance, final payment fees of $0.9 million, plus accrued interest and a prepayment premium aggregating $0.1 million. During the year ended December 31, 2024, the Company recorded a $0.4 million loss on the prepayment and extinguishment of the outstanding principal balance owed under the Amended Loan Agreement.

During the year ended December 31, 2024, the Company recorded interest expense of $3.3 million, which includes accretion of final payment fees, amortization of the underlying commitment fee and amortization of debt issuance costs totaling $0.8 million. The effective interest rate for all tranches of the debt was approximately 23.1% as of December 31, 2024.

(8) Warrants

Each whole Public Warrant and Private Warrant entitles the holder to purchase one share of Common Stock at a price of $11.50 per whole share, subject to adjustment as discussed below. Pursuant to the warrant agreement, a warrant holder may exercise its warrants only for a whole number of shares of Common Stock. The warrants will expire on March 2, 2027 at 5:00 p.m., New York City time, or earlier upon redemption or liquidation.

Public Warrants

When the price per share of the Company’s Common Stock equals or exceeds $18.00, the Company may redeem the outstanding warrants in whole and not in part, at a price of $0.01 per warrant as follows (except as described herein with respect to the Private Warrants):

upon a minimum of 30 days’ prior written notice of redemption to each warrant holder; and

if, and only if, the closing price of the shares of the Company’s Common Stock equals or exceeds $18.00 per share on the trading day prior to the date on which the Company sends the notice of redemption to the warrant holders.

81

Table of Contents

If the foregoing conditions are satisfied and the Company issues a notice of redemption of the warrants, each warrant holder will be entitled to exercise its warrant prior to the scheduled redemption date. Any such exercise would not be done on a “cashless” basis and would require the exercising warrant holder to pay the exercise price in cash for each warrant being exercised. The price of the shares of the Company’s Common Stock may fall below the $18.00 redemption trigger price as well as the $11.50 warrant exercise price after the redemption notice is issued.

When the price per share of the Company’s Common Stock equals or exceeds $10.00, the Company may redeem the outstanding warrants in whole and not in part, at a price of $0.10 per warrant as follows (except as described herein with respect to the Private warrants):

upon a minimum of 30 days’ prior written notice of redemption provided that holders will be able to exercise their warrants on a cashless basis prior to redemption as described below; and

if, and only if, the closing price of the Company’s Common Stock equals or exceeds $10.00 per share on the trading day prior to the date on which the Company sends the notice of redemption to the warrant holders.

Beginning on the date the notice of redemption is given until the warrants are redeemed or exercised, holders may elect to exercise their warrants on a cashless basis and could potentially receive up to a maximum of 0.361 shares of Common Stock per warrant or a minimum of 0.034 shares of Common Stock per warrant. The number of shares of Common Stock that a warrant holder will ultimately receive upon a cashless exercise in connection with a redemption by the Company, is based on the fair market value of the Company’s Common Stock on the redemption date, determined based on the volume weighted average price of the Company’s Common Stock for the 10 trading days ending on the third trading day prior to the date on which the notice of redemption is sent to the holders of the warrants, and the number of months that the corresponding redemption date precedes the expiration date of the warrants, as set forth in a table in the warrant agreement.

As of December 31, 2025 and December 31, 2024, Public Warrants issued and outstanding were 7,727,912 and 11,082,870, respectively (Refer to Note 4 for fair value measurement). The Public Warrants are accounted for as a derivative liability. The fair value of the Public Warrants is measured at each reporting period based on the listed price for the warrants, with subsequent changes in the fair value recognized in the consolidated statement of operations at each reporting date.

During the year ended December 31, 2025, a total of 4,346,386 Public Warrants were exercised, each for one share of Common Stock in exchange for cash proceeds of $11.50 per share. The proceeds from the warrant exercises totaled $50.0 million, and the underlying derivative liabilities for the Public Warrants on their respective exercise dates totaled $141.1 million. The proceeds from the warrant exercises and the underlying derivative liabilities for the Public Warrants on their exercise dates were recorded to par value of Common Stock and additional paid-in capital. No Public Warrants were exercised during the year ended December 31, 2024.

The calculated fair value of the derivative liability for the Public Warrants as of December 31, 2025 and December 31, 2024, was $85.8 million and $70.3 million, respectively. The change in the fair value of the Public Warrants included in the consolidated statement of operations during the years ended December 31, 2025 and December 31, 2024 was a loss of $142.4 million and a loss of $63.3 million, respectively.

Private Warrants

The Private Warrants have terms and provisions identical to those of the Public Warrants, including as to exercise price, exercisability and exercise period, except that if the Private Warrants are held by the initial purchasers, or such purchasers’ permitted transferees, then the Private Warrants are not redeemable by the Company and may be exercised for cash or on a cashless basis. If the Private Warrants are held by someone other the initial purchasers or such purchasers permitted transferees, then the Private warrants become Public Warrants and are redeemable by the company and exercisable by such holders on the same basis as the Public Warrants.

During the years ended December 31, 2025 and December 31, 2024, the number of Private Warrants that converted to Public Warrants as a result of transfer from the initial purchaser (or such purchaser’s permitted transferees) to other holders were 991,428 and 1,280,732, respectively.

As of December 31, 2025, and December 31, 2024, Private Warrants issued and outstanding were 1,000,674 and 1,992,102, respectively (Refer to Note 4 for fair value measurement). The Private Warrants are accounted for as a derivative liability. The fair value of the Private Warrants is determined using the Black-Scholes option-pricing model, with subsequent changes in the fair value recognized in the consolidated statements of operations at each reporting date.

Table of Contents

The calculated fair value of the derivative liability for the Private Warrants as of December 31, 2025 and December 31, 2024 was $16.8 million and $22.8 million, respectively. The change in the fair value of the Private Warrants included in the consolidated statements of operations during the years ended December 31, 2025 and December 31, 2024 was a loss of $8.2 million and a loss of $26.8 million, respectively.

Equity Classified Warrants

Series C Preferred Stock Financing Warrants

During 2020, a subsidiary of Legacy Rigetti issued and sold an aggregate of 54.5 million shares of its Series C Preferred Stock at a purchase price of $1.15 per share, for an aggregate purchase price of $56.2 million (the “Series C Preferred Stock Financing”). In conjunction with the Series C Preferred Stock Financing, the Company issued a total of 5,248,183 warrants to purchase Class A Common Stock to the Series C investors (the “Series C Warrants”). The Series C Warrants have a $0.01 per share exercise price and a 10-year term to expiration. The Series C Warrants can be exercised for cash or on a cashless basis.

The Company determined that the Series C Warrants met the requirements for equity classification under ASC 480 and ASC 815. The Company estimated the fair value of the Series C Warrants using the Black-Scholes model and allocated approximately $1.2 million in proceeds from the Series C Preferred Stock to the value of the Series C Warrants on a relative fair value basis, which was recorded to additional paid in capital.

As of December 31, 2025 and December 31, 2024, Series C Warrants issued and outstanding were 315,518 and 793,800 respectively.

Customer Warrant

In February 2020, the Company issued a warrant to purchase shares of its Class A Common Stock to a customer in conjunction with a revenue arrangement (the “Customer Warrant”). The Customer Warrant was assumed by the Company in connection with the Business Combination and converted into a warrant to purchase 2,680,607 shares of its Common Stock. The Customer Warrant has an exercise price of $1.152 per share and has a 10-year term to expiration. The Customer Warrant vests upon the achievement of certain performance conditions (i.e., sales milestones) defined in the agreement, and upon a change of control, either 50% or 100% of the then unvested Customer Warrant will become fully vested, dependent on the acquiring party in the change of control transaction. The Customer Warrant can be exercised for cash or on a cashless basis.

The Company followed the guidance in ASC 718 and ASC 606 for the accounting of non-cash consideration payable to a customer. The Company determined that the Customer Warrant met the requirements for equity classification under ASC 718 and measured the Customer Warrant based on its grant date fair value, estimated to be $0.2 million. The Company recorded this amount as a deferred asset and additional paid in capital as of the issuance date, as the Company believes it is probable that all performance conditions (i.e., sales milestones) in the Customer Warrant will be met. As of both December 31, 2025 and December 31, 2024, the deferred asset balance outstanding is approximately $0.1 million, which will be recognized as a reduction in revenue in future periods.

The vesting status of the Customer Warrant is as follows:

(9) Earn-out Liabilities

Upon the closing of the Business Combination on March 2, 2022, SNII, Supernova Partners II LLC (the “Sponsor”) and SNII’s directors and officers (collectively the “Sponsor Holders”) subjected certain shares of Common Stock (the “Sponsor Vesting Shares”) to forfeiture for a five-year period following the closing of the Business Combination, with vesting occurring only if thresholds related to the weighted average price of the Company’s Common Stock were met as described below (the “Earn-out Triggering Events”). Any Sponsor Vesting Shares that were not vested by the fifth anniversary of the closing of the Business Combination were to be forfeited.

Sponsor Vesting Shares – Vesting Provisions:

(i)2,479,000 shares of Common Stock held by the Sponsor Holders became unvested and subject to forfeiture as of the closing of the Business Combination and will only vest if, during the five year period following the closing of the Business Combination, the volume weighted average price of the Company’s Common Stock equals or exceeds $12.50 for any twenty trading days within a period of thirty consecutive trading days (such shares, the “Promote Sponsor Vesting Shares”), and
(ii)580,273 shares of Common Stock held by the Sponsor Holders became unvested and subject to forfeiture as of the closing of the Business Combination and will only vest if, during the five year period following the closing of the Business Combination, the volume weighted average price of the Company’s Common Stock equals or exceeds $15.00 for any twenty trading days within a period of thirty consecutive trading days (such shares, the “Sponsor Redemption-Based Vesting Shares,” and, collectively with the Promote Sponsor Vesting Shares, the “Sponsor Vesting Shares”).

During the year ended December 31, 2025, the Earn-out Triggering Events for each of the Sponsor Redemption-Based Vesting Shares and the Promote Sponsor Vesting Shares were satisfied, and the underlying earn-out liabilities were adjusted to fair value using the closing market price of the Company’s Common Stock on their respective vesting dates. The earn-out liability for the Sponsor Redemption-Based Vesting Shares as of their August 14, 2025 vesting date was $10.4 million. The earn-out liability for the Promote Sponsor Vesting Shares as of their February 6, 2025 vesting date was $32.9 million. The earn-out liabilities for the Sponsor Redemption-Based Vesting Shares and the Promote Sponsor Vesting Shares were recorded to additional paid-in capital on their respective vesting dates. As of December 31, 2025, all of the Sponsor Vesting Shares were vested and the earn-out liabilities balance was zero.

Prior to vesting, the Earn-out liabilities were adjusted to fair value each reporting period using the Monte Carlo simulation model. The change in the fair value of the Earn-out liabilities included in the consolidated statements of operations during the years ended December 31, 2025 and December 31, 2024 was a gain of $2.5 million and a loss of $43.7 million, respectively.

The calculated fair value of the Earn-out liabilities with respect to the Sponsor Vesting Shares as of December 31, 2024 was $45.9 million. Significant inputs into the Monte Carlo simulation model as of December 31, 2024 were as follows:

(10) Leases

The Company leases facilities for its fab-1, lab and office space, and equipment under various lease agreements with terms extending through 2029. Under the terms of the facility leases the Company bears the costs for certain insurance, property taxes and maintenance, and the lease agreements provide for increasing rental payments at fixed intervals.

On September 24, 2024, the Company entered into a lease amendment for its corporate headquarters located in Berkeley, California which, among other things, extends the lease term by three years to October 31, 2028, sets a new annual rental rate of approximately $0.9 million effective as of November 1, 2025 and provides an option to extend the lease for an additional five years.

Rental rates increase at the rate of 3% per year over the lease term and the five year option period. The Company did not include the five year option as part of its right-of-use assets and lease liabilities because exercise of the option was deemed unlikely.

During the year ended December 31, 2024, the Company remeasured the lease liability for its Berkeley headquarters facility over the remaining lease term of 4.1 years using an incremental borrowing rate of 6.32%. The effect of the lease amendment increased the Company’s operating lease right-of-use assets and operating lease liabilities by $2.3 million.

During the year ended December 31, 2025, there were no new operating leases with a lease term greater than 12 months. During the year ended December 31, 2024, there were no new operating leases with a lease term greater than 12 months except for the lease amendment for the Berkeley headquarters facility mentioned above.

As of December 31, 2025 and December 31, 2024 the weighted-average remaining lease term is approximately 3.46 years and 4.44 years, respectively, and the weighted-average discount rate is 7.68% and 7.65%, respectively.

Operating lease liabilities are based on the net present value of the remaining lease payments over the remaining lease term. In determining the net present value of its lease payments, the Company used an estimated incremental borrowing rate that is applicable to the Company based on the information available at the later of the lease commencement date, lease modification date or the date of Adoption of Topic 842.

The Company’s outstanding stock options generally have exercise prices equal to fair market value on the date of grant, expire after ten years and have service-based vesting conditions ranging from 1-5 years, except that 500,000 stock options granted in 2022 have a market-based vesting condition tied to the Company’s Common Stock price. The vesting condition with respect to the market-based stock option grants was satisfied in January 2025.

There were no stock options granted during the year ended December 31, 2025. The weighted-average grant date fair value of stock options granted during the year ended December 31, 2024, was $1.27. The intrinsic value of a stock option is the amount by which the market price of the underlying Common Stock exceeds the option’s exercise price. The intrinsic value of stock options exercised during the years ended December 31, 2025 and December 31, 2024, was $34.7 million and $4.5 million, respectively. The Company received proceeds from stock option exercises during the years ended December 31, 2025 and December 31, 2024 of $2.0 million and $0.6 million, respectively.

Stock-based compensation expense related to stock options was $1.9 million for each of the years ended December 31, 2025 and December 31, 2024. As of December 31, 2025, the unrecognized compensation expense related to unvested stock options was $2.3 million, which is expected to be recognized over a weighted-average period of 1.64 years.

Fair Value of Stock Option Grants

The fair value of each stock option award is estimated on the date of grant using the Black-Scholes option-pricing model that uses the assumptions noted in the tables below.

87

Table of Contents

For the first nine months of 2024, expected volatility for the Company’s Common Stock was determined based on a blended average of the historical volatility of a peer group of similar public companies, the historical volatility of the Company’s Common Stock and the implied volatility from the Company’s Public Warrants. For the last three months of 2024, expected volatility for the Company’s Common Stock was determined based on a one-third weighting of the historical volatility of a peer group of similar public companies and a two-thirds weighting of the historical volatility of the Company’s Common Stock. The implied volatility from the Company’s Public Warrants was excluded because the calculation did not produce a meaningful result. The Company had not been public for a sufficient length of time to derive expected volatility solely from trading in its Common Stock.

The expected term of stock options granted was calculated using the simplified method, which represents the average of the contractual term and the weighted-average vesting period of the option. The Company uses the simplified method because it does not have sufficient historical exercise data for its options to provide a reasonable basis upon which to estimate the expected term.

The assumed dividend yield was based upon the Company’s expectation of not paying dividends in the foreseeable future. The risk-free rate was based upon the U.S. Treasury yield curve in effect at the time of grant for the period equivalent to the expected term of the stock option. In determining the exercise prices for stock options granted, the Company’s board of directors has utilized the fair value of the Common Stock as of the grant date.

Before the Business Combination, the fair value of the Common Stock had been determined by the board of directors at each award grant date based upon a variety of factors, including the results obtained from an independent third-party valuation, the Company’s financial position and historical financial performance, the status of technological developments within the Company, the composition and ability of the current engineering and management team, an evaluation or benchmark of the Company’s competition, the current business climate in the marketplace, the illiquid nature of the Company’s Common Stock, arm’s-length sales of the Company’s capital stock, the effect of the rights and preferences of the preferred shareholders, and the prospects of a liquidity event, among others.

The range of valuation assumptions used as inputs to the Black-Scholes option-pricing model to value service-based stock options granted during the year ended December 31, 2024 were as follows:

As of December 31, 2025, all of the Company’s non-vested RSUs have a service-based vesting condition ranging from 1-4 years. During the year ended December 31, 2023, the Company granted 3,850,000 RSUs with a market-based vesting condition tied to the Company’s stock price. Based upon the terms of such awards, 50% of the shares became vested when the Company’s Common Stock traded at or above $2.00 per share and the other 50% of the shares became vested when the Company’s Common Stock traded at or above $4.00 per share, for 20 out of 30 trading days through the fifth anniversary of the grant date. The $2.00 per share vesting condition was satisfied in December 2024, and the $4.00 per share vesting condition was satisfied in January 2025.

The income tax withholding obligation for all RSUs are satisfied through the sale of shares into the market, otherwise known as Sell-To-Cover (“STC”). The STC transaction and the income tax withholding remittance for the market-based RSUs that vested in December 2024 took place on December 30, 2024. The $6.3 million proceeds from the STC were received by the Company on January 2, 2025, and is included in other current assets in the accompanying balance sheet as of December 31, 2024.

The weighted-average grant date fair value of RSUs granted during the years ended December 31, 2025 and December 31, 2024, was $14.02 and $1.07 per share, respectively. The aggregate fair value of outstanding RSUs based on the closing share price of the Company’s Common Stock as of December 31, 2025 and December 31, 2024, was $162.4 million and $170.6 million, respectively.

Table of Contents

The aggregate fair value of RSUs that vested based on the closing price of the Company’s Common Stock on the vesting date during the years ended December 31, 2025, and December 31, 2024, was $80.5 million and $28.4 million, respectively.

Fair Value of RSUs Awards

The number of service-based RSUs granted during the years ended December 31, 2025 and December 31, 2024 was 3,722,285 and 7,380,872, respectively. The service-based RSUs vest over periods ranging from 1-4 years and require continuous employment. The fair value of the Company’s service-based RSUs was calculated based on the fair market value of the Company’s Common Stock on the date of grant.

Stock-based compensation expense related to RSUs was $15.7 million and $11.2 million for the years ended December 31, 2025 and December 31, 2024, respectively. As of December 31, 2025, the unrecognized compensation expense related to unvested RSUs was $49.8 million which is expected to be recognized over a weighted-average period of 2.45 years.

The vesting condition for all 2,479,000 Promote Sponsor Vesting Shares was satisfied on February 6, 2025, and the vesting condition for all 580,273 Sponsor Redemption-Based Vesting Shares was satisfied on August 14, 2025. For the year ended December 31, 2025, the Promote Sponsor Vesting Shares and the Sponsor Redemption-Based Vesting Shares have been included in the computations of basic and diluted net loss per share from their respective vesting dates. The Promote Sponsor Vesting Shares and the Sponsor Redemption-Based Vesting Shares were not included in the computations of basic and diluted net loss per share for the year ended December 31, 2024, because the vesting conditions related to these shares had not been met.

The weighted-average common shares outstanding for the years ended December 31, 2025 and December 31, 2024 include 682,939 and 963,297 weighted-average shares for warrants having an exercise price of $0.01 per share each, respectively. The Company’s potential dilutive securities, which include stock options, restricted stock units and warrants have been excluded from the computation of diluted net loss per share as the effect would be anti-dilutive. Therefore, the weighted average number of common shares outstanding used to calculate both basic and diluted net loss per share is the same.

Revenues from external customers are attributed to individual countries based on the physical location in which the services are provided or the particular customer location with whom the Company has contracted.

Financial instruments that potentially subject the Company to concentrations of credit risk consist primarily of cash and cash equivalents and trade accounts receivable. The Company’s cash and cash equivalents are placed with high-credit-quality financial institutions, and at times exceed federally insured limits. To date, the Company has not experienced any credit loss relating to its cash and cash equivalents.

Significant customers that represent 10% or more of revenue are set forth in the following tables:

The Company did not pay any income taxes for the years ended December 31, 2025 or December 31, 2024. All components of the Company’s current and deferred income tax provisions for the years ended December 31, 2025 and December 31, 2024 were zero. The effective tax rate differs from the statutory rate, primarily due to the Company’s history of incurring losses which have not been benefited, write-off of federal and state net operating loss carryforwards and research and development tax credit carryforwards under Internal Revenue Code (IRC) section 382 limitation, stock-based compensation and other permanent differences.

On July 4, 2025, new federal tax and budget legislation, known as the “One Big Beautiful Bill Act” (“OBBA”) was signed into law. The Company evaluated the impact of the OBBA and determined that its provisions did not have a material impact on the consolidated financial statements.

Upon adoption of ASU 2023-09, Improvement to Income Tax Disclosures, as described in Note 2, Summary of Significant Accounting Policies, the reconciliation of taxes at the federal statutory rate to the Company’s provision for income taxes for the year ended December 31, 2025, was as follows (in thousands, except for percentages):

Realization of deferred tax assets is dependent upon future earnings, if any, the timing and amount of which are uncertain. Accordingly, the net U.S. federal and state deferred tax assets have been fully offset by a valuation allowance. The net change in total valuation allowance increased by approximately $33.2 million and $17.9 million for the years ended December 31, 2025 and December 31, 2024, respectively.

As of December 31, 2025, the Company had net operating loss carryforwards for federal income tax purposes of $455.3 million, of which $453.9 million does not expire; federal research and development tax credits of $14.1 million, which will start to expire in 2044; net operating loss carryforwards for state income tax purposes of $193.3 million, which will start to expire in 2038; and state research and development tax credits of $12.6 million, which do not expire.

Under Section 382 of the Internal Revenue Code of 1986, as amended, the Company’s federal net operating loss carryforwards and research and development tax credit carryforwards, and other tax attributes are subject to annual limitation because of prior cumulative changes in the Company’s ownership and may be further limited in the future if additional ownership changes occur. Similar rules apply under state tax laws. These ownership changes limit the amount of net operating loss carryforwards and research and development tax credit carryforwards that can be utilized annually to reduce the Company’s federal and state income tax liabilities, if any. Such annual limitations could result in the expiration of the net operating loss carryforwards and research and development tax credit carryforwards before their utilization.

Table of Contents

During the year ended December 31, 2024, the Company assessed whether an ownership change, as defined by Section 382, occurred during the period from January 1, 2023 through December 31, 2024. Based upon the assessment conducted in 2024, the Company concluded that an ownership change occurred in November of 2024; however, based on the annual limitation from the November 2024 ownership change, none of the net operating losses or research and development tax credits are expected to expire prior to their potential use, as such there was no reduction to the gross deferred tax assets during the year ended December 31, 2024. The Company also assessed whether an ownership change occurred during the year ended December 31, 2025. Based on the results of this assessment, the Company determined that an ownership change as defined by Section 382 did not occur during the year ended December 31, 2025.

The Company files U.S. and various state income tax returns as well as foreign income tax returns in Australia, Canada and the United Kingdom with varying statutes of limitations. All tax years from inception in 2013 remain open to examination due to the carryover of unused net operating losses and tax credits. The Company had unrecognized tax benefits of $24.1 million as of December 31, 2025, all of which are offset by a full valuation allowance. These unrecognized tax benefits, if recognized, would not affect the effective tax rate. There were no interest or penalties accrued as of December 31, 2025.

A reconciliation of the beginning and ending amounts of unrecognized income tax benefits is as follows:

(17) Collaborative Arrangements

On February 27, 2025, the Company entered into a Collaboration Agreement (the “Collaboration Agreement”) with Quanta Computer Inc., a Taiwan corporation (“Quanta”). The term of the Collaboration Agreement is for five years, subject to cancellation under certain circumstances.

Pursuant to the Collaboration Agreement, during the five year period following February 27, 2025, the Company has agreed it will invest at least $250.0 million in the field of quantum computing, in furtherance of its product roadmap, and Quanta has agreed it will invest at least $250.0 million in the field of quantum computing, and the investment by Quanta will be towards personnel and capital expenditures for developing products and services and manufacturing capability in furtherance of the Company’s product roadmap. No equity or joint venture was formed under the Collaboration Agreement. Costs incurred by the Company under the Collaboration Agreement, consisting of its expenditures for research and development and related capital, will be accounted for in accordance with GAAP as incurred.

Under the Collaboration Agreement, the Company will retain all rights, title and ownership to all QPU Technology (as defined in the Collaboration Agreement) and related intellectual property (IP) rights created in the course of activities specified in a statement of work under the Collaboration Agreement. Other than the QPU Technology and IP rights described above, to the extent there is any jointly created, invented or other developed technology in the course of the performance of activities specified in a statement of work under the Collaboration Agreement, the Company and Quanta will jointly own, and each party will hold a one-half undivided interest in, all such joint project technology and all newly-created or newly-arising IP rights with respect thereto.

In connection with the Collaboration Agreement, on February 27, 2025, the Company entered into a securities purchase agreement with Quanta, pursuant to which the Company agreed to sell and issue to Quanta in a private placement transaction 3,020,412 shares of its Common Stock at a price per share of approximately $11.59, for an aggregate value of approximately $35.0 million. The price per share was based on the volume weighted-average price of the Company’s Common Stock for the 15 trading days prior to February 27, 2025. The private placement transaction, which was subject to regulatory clearance, closed on April 29, 2025. In connection with the private placement transaction, Quanta entered into a board observer and confidentiality agreement under which it has the option and right to appoint a single representative to attend certain meetings of the board of directors of the Company, subject to exceptions, in a non-voting observer capacity. The securities purchase agreement also contains a lock-up provision prohibiting Quanta from selling any of the shares of the Company’s Common Stock acquired in the securities purchase agreement for a three year period following the closing of the private placement transaction.

Indemnification Provisions

The Company’s agreements include provisions indemnifying customers against intellectual property and other third-party claims. In addition, the Company has entered into indemnification agreements with its directors, executive officers and certain other officers that require the Company, among other things, to indemnify them against certain liabilities that may arise as a result of their affiliation with the Company.

ITEM 9B.OTHER INFORMATION

Amendment and Restatement of Bylaws

On February 27, 2026, our board of directors approved and adopted the Second Amended and Restated Bylaws of the Company (the “Second Amended and Restated Bylaws”), effective as of such date. The Second Amended and Restated Bylaws modify the provisions for determining the presence of a quorum at all meetings of stockholders to provide that the presence, in person, by remote communication, if applicable, or by proxy duly authorized, of the holders of one-third (33-1/3%) of the voting power of the outstanding shares of stock entitled to vote at a meeting of stockholders shall constitute a quorum for the transaction of business. Prior to the amendment and restatement, the presence, in person, by remote communication, if applicable, or by proxy, of the holders of a majority of the voting power of the outstanding shares of stock entitled to vote at a meeting of stockholders, constituted a quorum for the transaction of business.

96

Table of Contents

In addition, the Second Amended and Restated Bylaws update certain requirements in the advance notice provisions to align them to current best practices, including (i) removing the requirement for a stockholder nominating a director to our board to provide a statement whether such nominee, if elected, would intend to tender a resignation promptly following such person’s failure to receive the required vote for election or re-election and (ii) clarifying that a written notice provided by a stockholder with respect to a director nominee shall include, to the extent known by such stockholder, the name and address of any other stockholder providing financial support for the stockholder’s proposal (previously, the requirement was to provide the name and address of any other stockholder supporting such proposal). The Second Amended and Restated Bylaws also make certain other technical, modernizing and clarifying changes.

The foregoing description of the changes contained in the Second Amended and Restated Bylaws does not purport to be complete and is qualified in its entirety by reference to the full text thereof, a copy of which is attached hereto as Exhibit 3.2 to this Annual Report on Form 10-K and is incorporated herein by reference.
