Overview

We are developing quantum computers and networks designed to solve some of the world’s most complex problems, and transform business, society and the
planet for the better. We believe that our proprietary technology, our architecture, and the technology exclusively available to us through license agreements will offer us advantages both in terms of research and development, as well as the
commercial value of our intended product offerings.

Today, we sell specialized quantum computing and networking hardware together with related
maintenance and support. We also sell access to several quantum computers of various qubit capacities and are in the process of researching and developing technologies for quantum computers with increasing computational capabilities. We currently
make access to our quantum computers available via three major cloud platforms, Amazon Web Services’ (“AWS”) Amazon Braket, Microsoft’s Azure Quantum and Google’s Cloud Marketplace, and also to select customers via our own
cloud service. This cloud-based approach enables the broad availability of quantum-computing-as-a-service (“QCaaS”).

We supplement our offerings with professional services focused on assisting our customers in applying quantum computing and networking to their
businesses. We also expect to sell full quantum computing systems to customers, either over the cloud or for local access. We also offer quantum networking products which offer customers secure communication networks and enable networked quantum
computing.

We are still in the early stages of commercial growth. Since our inception, we have incurred significant operating losses. Our ability to
generate revenue sufficient to achieve profitability will depend heavily on the successful development and further commercialization of our quantum computing systems. As of December 31, 2024, we had an accumulated deficit of
$683.7 million. We expect to continue to incur significant losses for the foreseeable future as we prioritize reaching the technical milestones necessary to achieve an increasingly
