DPCM Capital Announces Filing of Registration Statement on Form S-4 in Connection with its Proposed Business Combination with D-Wave

Reports over 100% growth in Forbes Global 2000 Customers

DPCM Capital, Inc. (NYSE:XPOA), a publicly traded special purpose acquisition company ("DPCM Capital"), today announced the filing with the U.S. Securities and Exchange Commission (the "SEC") by D-Wave Quantum Inc., a wholly-owned subsidiary of DPCM Capital ("D-Wave Quantum"), of a registration statement on Form S-4 (the "Registration Statement") in connection with the previously announced business combination (the "Transaction") between DPCM Capital and D-Wave Systems Inc. ("D-Wave"), a leader in quantum computing systems, software, and services—and the only quantum company building both annealing and gate-model quantum computers.

The Registration Statement contains a preliminary proxy statement and prospectus in connection with the Transaction. While the Registration Statement has not yet become effective and the information contained therein is subject to change, it provides important information about D-Wave and the Transaction, including with respect to D-Wave's unique value to customers and investors as the only quantum computing company that has:

• More than two dozen Forbes Global 2000 customers, representing a doubling of the number in 2020 with the year-over-year growth driven primarily in the financial services, manufacturing, and pharmaceuticals sectors
• A highly diversified customer base with Quantum Computing as a Service (QCaaS) from commercial customers representing 68% of 2021 total revenue
• Annealing quantum technology necessary to solve commercial combinatorial optimization problems that is estimated to represent approximately 25% of the quantum total available market (TAM)
• Fifteen plus years of developing and building annealing quantum computers, uniquely enabling D-Wave to address today's optimization portion of the quantum market for applications in important-use cases such as employee scheduling, last-mile vehicle routing, manufacturing-plant floor optimization, supply chain optimization and many others
• A powerful combination of both professional services and quantum computing as a service (QCaaS) to aid in the development and deployment of hybrid quantum business applications
• Demonstrated application speed-ups on important real-world problems
• A dual-product approach to building both annealing and gate-model quantum computers enabling D-Wave to address the full quantum market
• Developed and introduced 5 generations of increasingly powerful quantum computing systems
• A track record of operational and commercial experience running a quantum computing business at scale
• An intent to continue to build on the more than 200 US patents that have been granted to D-Wave since its founding in 1999

Completion of the Transaction, which is expected to occur in the second quarter of 2022, is subject to the Registration Statement being declared effective by the SEC; the approval of the Transaction by DPCM Capital's stockholders and D-Wave's shareholders, respectively; and other customary closing conditions. DPCM Capital's shares of Class A common stock and warrants to purchase shares of Class A common stock currently are traded on the New York Stock Exchange ("NYSE") under the symbols "XPOA" and "XPOA.WT", respectively. Upon completion of the Transaction, shares of D-Wave Quantum common stock, a newly formed parent company of D-Wave and DPCM Capital, and warrants to purchase D-Wave Quantum common stock are expected to be traded on the NYSE under the ticker symbols "QBTS" and "QBTS.WS", respectively.

"We remain excited about the pending business combination with D-Wave and look forward to working with its talented team to accelerate quantum use cases into customer segments, including manufacturing, logistics, pharmaceuticals, finance, and government," said Emil Michael, CEO of DPCM Capital. "D-Wave is uniquely positioned as the only quantum computing company with full access to an expected $150 billion total market opportunity and is already delivering the significant benefits of quantum computing to major companies across the globe. As the only quantum computing company in the world that is building both annealing and gate-model quantum computers, we are confident that D-Wave will continue to deliver long-term value to stockholders."

"We are on-track with the transaction process, and we believe becoming a publicly-traded company will help us create value for our customers and for our investors through market growth, further hybrid quantum application development, and expansion of our product portfolio."
