SueWallSt Reminds Shareholders of a Lead Plaintiff Deadline of December 15, 2026 in D-Wave Quantum Inc. Lawsuit - QBTS

Statutory Notice: Section 10(b) and Rule 10b-5 claims pending in the Northern District of California allege D-Wave overstated its growth prospects before QBTS shed $1.99 and then $1.84 per share in two August 2026 trading sessions.

NEW YORK, Nov. 12, 2026 /PRNewswire/ -- SueWallSt notifies shareholders of D-Wave Quantum Inc. (NYSE: QBTS) that a class action asserting claims under the Securities Exchange Act of 1934 is pending on behalf of investors who purchased or otherwise acquired D-Wave securities between February 26, 2026 and August 25, 2026. Submit your information now, or contact Joseph E. Levi, Esq. at [email protected] or (888) SueWallSt.

QBTS shed $1.99 per share on August 6, 2026 and another $1.84 per share on August 26, 2026. Together, those two single-session declines total $3.83 per share, and the complaint attributes them to alleged Exchange Act violations. IMPORTANT DATE: December 15, 2026 is the last day for investors to ask the Court to appoint them lead plaintiff.

The Exchange Act Provisions Invoked Against D-Wave

Section 10(b) and SEC Rule 10b-5 bar untrue statements of material fact, and omissions that make statements misleading, in connection with the purchase or sale of securities. As pleaded, D-Wave's Class Period press releases and market communications violated those rules by materially overstating the Company's business and financial prospects. The action further contends that management failed to disclose that this alleged overstatement was reasonably likely to damage the Company's business and reputation.

Alleged Disclosure Duties and the August Corrective Events

The lawsuit describes a duty owed by a publicly held company and its senior officers to disseminate timely, accurate information about operations and future prospects, and to promptly correct statements that had become materially misleading. Plaintiffs allege the challenged statements, which addressed the Company's business, operations, and compliance policies, were misleading from February 26, 2026 onward. The complaint asserts that two announcements corrected those prior alleged misstatements: an August 6, 2026 second quarter report showing revenue below analyst expectations, and an August 25, 2026 announcement that the Chief Financial Officer would retire.

Exchange Act Claims at a Glance

• Count I: Section 10(b) and Rule 10b-5, asserted against D-Wave and two individual defendants over alleged untrue statements, omissions, and a scheme to defraud purchasers.
• Count II: Section 20(a), asserted against the individual defendants as alleged controlling persons of the Company.
• Jurisdiction: 28 U.S.C. § 1331 and Section 27 of the Exchange Act.
• Venue: U.S. District Court for the Northern District of California, where D-Wave is headquartered in Palo Alto.
• Relief sought: Damages, pre-judgment and post-judgment interest, and costs, with a jury trial demanded.

"Section 10(b) and Rule 10b-5 require that what a public company tells the market about its own prospects be accurate at the time it is said. The complaint alleges that D-Wave's optimistic descriptions of its 2026 trajectory overstated those prospects, and that shareholders bore the cost when the August disclosures arrived. QBTS purchasers from the Class Period may wish to review how these Exchange Act claims apply to their own trades." -- Joseph E. Levi, Esq.
