What Does the Complaint Allege?
D-Wave sells cloud access to its quantum computers, professional services and the systems themselves. The complaint quotes the company’s February 26, 2026 fourth-quarter and full-year 2025 results release, in which the CEO said D-Wave was entering 2026 with “exceptional momentum” and called 2026 “a defining year,” and its May 12, 2026 first-quarter release, which highlighted a record $10 million computing-as-a-service deal with a Fortune 100 company. The plaintiff alleges those statements were materially false or misleading because the defendants overstated D-Wave’s operational and financial prospects.According to the complaint, the alleged truth came out in two steps:
- August 6, 2026: D-Wave reported second-quarter revenue of $3.08 million, compared with $3.1 million a year earlier and below analyst expectations of about $4.03 million to $4.08 million. The stock fell $1.99, or 9.28%, to close at $19.41.
- August 25, 2026: D-Wave announced that CFO John Markovich was retiring and would step down effective September 2, 2026. The stock fell $1.84, or 9.51%, to close at $17.51 on August 26.
The complaint alleges the defendants acted knowingly or recklessly. It does not allege that D-Wave restated any financial results, and its theory of what was concealed is stated in general terms. D-Wave has not been found liable for anything.
Who Is in the Proposed Class?
The proposed class is all persons and entities that purchased or otherwise acquired D-Wave securities between February 26, 2026 and August 25, 2026, inclusive, and were damaged when the alleged corrective disclosures came out. The defendants, D-Wave’s officers and directors, their immediate families, legal representatives, heirs and assigns, and entities they control are excluded. No class has been certified; the court decides that later in the case.What Happens Next?
Securities class actions follow the Private Securities Litigation Reform Act. Within 20 days of filing, the plaintiff must publish notice of the case, and investors then have 60 days from that notice to ask the court to appoint them lead plaintiff, the investor who directs the case on the class’s behalf. The court picks a lead plaintiff and lead counsel, and an amended complaint usually follows, which the defendants typically challenge with a motion to dismiss. Discovery is generally paused until that motion is decided.Seeking the lead plaintiff role is optional. Members of a proposed securities class generally remain in the class without it, and there is nothing to file and no money available unless the case produces a judgment or settlement, which would come with its own court-approved notice and claim process.

The defendants, D-Wave’s officers and directors, their immediate families and affiliated entities are excluded. No class has been certified.
What does the D-Wave lawsuit say the company did wrong?
The complaint alleges that D-Wave and its CEO and CFO materially overstated the company’s business and financial prospects in its fourth-quarter 2025 and first-quarter 2026 results announcements. It points to an August 6, 2026 second-quarter revenue report of $3.08 million that missed analyst expectations, and an August 25, 2026 announcement that the CFO was retiring. These are unproven allegations, and D-Wave has not yet responded in court.

No. The case was filed on October 15, 2026 and is at the complaint stage. There is no settlement, judgment or claim form. Money would only become available if the case later settles or produces a judgment, which would come with its own court-approved notice and claim process.
What is the lead plaintiff deadline in the D-Wave case?
Under the Private Securities Litigation Reform Act, investors may ask the court to appoint them lead plaintiff within 60 days after the first notice of the case is published. The lead plaintiff role is optional; class members who do not seek it generally remain members of the proposed class.
