Allegations in the D-Wave Quantum, Inc. lawsuit

The D-Wave Quantum, Inc. shareholder lawsuit alleges that, throughout the class period, defendants made materially false and/or misleading statements and failed to disclose material adverse facts about D-Wave Quantum, Inc.'s business, operations, and prospects. Specifically, the complaint alleges defendants failed to disclose to investors that: (1) Defendants materially overstated D-Wave’s business and financial prospects; (2) the foregoing was reasonably likely to negatively impact the Company’s business and reputation; and (3) as a result, defendants' positive statements about D-Wave Quantum, Inc.'s business, operations, and prospects were materially misleading and/or lacked a reasonable basis at all relevant times.
