Notice to Pension Funds, Asset Managers, and ERISA Fiduciaries: a securities lawsuit alleges D-Wave overstated its growth momentum ahead of a revenue miss and a CFO departure. Institutional investor securities recovery options are now under review.

NEW YORK, Oct. 21, 2026 /PRNewswire/ -- Levi & Korsinsky, LLP notifies institutional investors in D-Wave Quantum Inc. (NYSE: QBTS) that a class action lawsuit has been filed on behalf of shareholders who purchased securities between February 26, 2026 and August 25, 2026. Request an institutional investor loss assessment. You may also contact Joseph E. Levi, Esq. at [email protected] or (212) 363-7500.

A fund that held 100,000 QBTS shares through both August 2026 disclosure days lost roughly $383,000 in market value. A 1,000,000-share position shed approximately $3.83 million, based on combined declines of $3.83 per share. Those wishing to serve as lead plaintiff must act by December 15, 2026.

Portfolio Impact Assessment for QBTS Holders

The securities action alleges that D-Wave materially overstated its business and financial prospects during the Class Period. It further alleges that this overstatement was reasonably likely to damage the Company's business and reputation. QBTS fell after D-Wave reported second quarter 2026 revenue below analyst expectations on August 6, 2026, and fell again after the Company announced on August 25, 2026 that its chief financial officer would retire.

Quantum computing stocks may sit inside thematic technology, small-cap growth, and index-tracking mandates. As a result, a single plan sponsor may have recorded QBTS losses across several accounts and sub-advisers.

Institutional Investor Recovery: ERISA and Fiduciary Considerations

Trustees and investment committees overseeing ERISA plans, public pensions, and endowments may wish to confirm whether their portfolios bought D-Wave securities during the Class Period. They may also wish to weigh participation in the case against their duties to beneficiaries.

"Institutional investors play a critical role in securities class actions, especially in a case like this one. Here, the complaint alleges that upbeat growth messaging gave way to a quarterly revenue shortfall and, less than three weeks later, the departure of the Company's chief financial officer. Fiduciaries with meaningful D-Wave exposure may want to review their Class Period purchases while the lead plaintiff window remains open," said Joseph E. Levi, Esq.

Fiduciary Obligations and Recovery Options

Class Period alignment: Purchases or acquisitions of D-Wave securities from February 26, 2026 through August 25, 2026 define potential class membership, whether or not the shares are still held.
Lead plaintiff consideration: Courts typically favor the movant with the largest financial interest. This can position institutions with sizable QBTS holdings to oversee the case and its counsel.
Passive participation: Funds that do not seek appointment may still share in any recovery as absent class members.
Cost: Reviewing QBTS trading data with the firm involves no out-of-pocket fees.
Records: Gather custodial statements and trade files from every manager and sub-adviser that held QBTS during the Class Period.
