In connection with the potential business combination transaction (the “Transaction”) pursuant to which D-Wave Systems Inc. (“D-Wave”) and DPCM Capital, Inc.

D-Wave Quantum and DPCM urge investors, stockholders and other interested persons to read, when available, the preliminary proxy statement/prospectus, as well as other documents filed with the SEC, because these documents will contain important information about D-Wave Quantum, DPCM, D-Wave and the Transaction. After the registration statement is declared effective, the definitive proxy statement/prospectus to be included in the registration statement will be mailed to stockholders of DPCM as of a record date to be established for voting on the Transaction. Once available, shareholders will also be able to obtain a copy of the registration statement on Form S-4—including the proxy statement/prospectus and other documents filed with the SEC without charge—by directing a request to: D-Wave Quantum Inc., 3033 Beta Avenue, Burnaby, BC V5G 4M9 Canada, or via email at shareholdercomm@dwavesys.com and DPCM Capital, 382 NE 191 Street, #24148, Miami, Florida 33179, or via email at mkilkenny@hstrategies.com.
