Bronstein Gewirtz & Grossman Files Class Action Against D-Wave Quantum Inc.

In a significant legal move, Bronstein Gewirtz & Grossman, LLC, a well-known investor-rights law firm, has initiated a class action lawsuit against D-Wave Quantum Inc. (NASDAQ: QBTS). This action addresses allegations of securities fraud and aims to recover financial losses for investors who acquired D-Wave stocks between February 26, 2026, and August 25, 2026. The lawsuit was officially filed on October 15, 2026, in the United States District Court for the Northern District of California (Case No. 526-cv-11953).

Allegations of Misleading Information

The core of the lawsuit alleges that D-Wave’s officers made misleading statements concerning the company's business operations and financial performance during the class period. Investors are claiming that they were misled by excessive positive portrayals of D-Wave’s prospects, which did not reflect the company’s actual performance. These allegations include assertions that D-Wave overstated its business and operational standing, implying a false sense of security regarding the company’s growth and market stability.

The complaint highlighted specific incidents that led to a significant drop in D-Wave’s stock value. On August 6, 2026, the company announced its second-quarter revenue of $3.08 million, which fell short of analysts' projections of around $4.03 million to $4.08 million. This disappointing report resulted in a steep decline of $1.99, equating to a 9.28% drop in the stock price, which closed at $19.41 per share.

Further compounding investors' frustrations, on August 25, 2026, D-Wave announced the retirement of its Chief Financial Officer, John Markovich, effective September 2, 2026. This news led to another fall in the stock price, reducing it by an additional $1.84 (9.51%) to close at $17.51 per share on August 26, 2026.
