Allegations Against D-Wave Quantum and Key Events Cited in the Complaint

According to the filing, the complaint alleges that during the class period, defendants "materially overstated D-Wave's business and financial prospects" and that their public statements "were materially false and misleading at all relevant times." The complaint further alleges that this was "reasonably likely to negatively impact the Company's business and reputation." Robbins LLP attributed these characterizations to the complaint; they represent allegations, not established findings.

The filing states that disclosures began on August 6, 2026, when D-Wave reported Q2 2026 revenue of $3.08 million. According to the complaint, this figure fell short of analyst expectations ranging from $4.03 million to $4.08 million and was below the $3.1 million reported for the same period in the prior year. On that date, D-Wave's stock price declined $1.99 per share, or 9.28%, to close at $19.41 per share.

A second stock decline is cited in connection with the August 25, 2026 press release disclosing that John Markovich was retiring and resigning as Chief Financial Officer effective September 2, 2026. According to the complaint, D-Wave's stock fell $1.84 per share, or 9.51%, closing at $17.51 per share on August 26, 2026. The filing notes that shareholders do not need to serve as lead plaintiff to participate in any potential recovery, and that absent class members may remain eligible.
