D-Wave Quantum Inc. is facing a securities class action in the United States District Court for the Northern District of California, while Robbins LLP urges investors who purchased or acquired the company’s securities from February 26, 2026, through August 25, 2026, inclusive, to contact the firm. The existing case, captioned Fessler v. D-Wave Quantum Inc., No. 26-cv-11953, alleges that D-Wave and certain current and former executives overstated the company’s business and financial prospects and failed to disclose risks to its business and reputation. The complaint cites second-quarter 2026 revenue of $3.08 million, compared with $3.1 million a year earlier and analyst expectations of $4.03 million to $4.08 million. D-Wave shares fell $1.99, or 9.28%, to $19.41 on August 6, according to the complaint, and declined another $1.84, or 9.51%, to $17.51 on August 26 after the company announced Chief Financial Officer John Markovich’s retirement and resignation. Robbins LLP says investors should contact it before December 15, 2026, to seek lead-plaintiff appointment. An earlier investor notice cited December 14, 2026, as the deadline, creating a discrepancy that investors should verify. Investors do not need to become lead plaintiff to participate in any potential recovery.
