Zymergen Securities Litigation

Welcome to the Zymergen Securities Litigation Website

This website has been established to provide general information related to the proposed Settlement of the consolidated securities matter captioned Wang v. Zymergen Inc., et al., Case No. 5:21-cv-06028-PCP (the "Action" or “Litigation”), presently pending before the Honorable P. Casey Pitts of the United States District Court for the Northern District of California, San Jose Division (the “Court”). The capitalized terms used on this website, and not otherwise defined, shall have the same meanings ascribed to them in the Stipulation of Settlement dated March 23, 2026 (the “Stipulation”), which can be found and downloaded by clicking on the Court Documents tab above.

Pursuant to the Court’s Order dated August 11, 2023, the Court certified this securities case as a class action to proceed on behalf of the Class. The Lead Plaintiff is Biao Wang, on behalf of himself and the Class.

In September 2023, a Notice of Pendency of Class Action was mailed to potential Class Members advising them of their options relating to the Action that included remaining in the Action or excluding themselves from the Class.    

The parties have now reached a proposed Settlement, and, on June 22, 2026, the Court granted Lead Plaintiff’s unopposed motion for preliminary approval of the Settlement.

The “Class,” as certified by the Court, consists of:  All persons and entities who purchased or otherwise acquired Zymergen common stock pursuant and/or traceable to the Registration Statement and prospectus issued in connection with Zymergen’s April 2021 initial public offering.

Excluded from the Class are Defendants, the officers and directors of Defendants, at all relevant times, members of their immediate families and their legal representatives, heirs, successors, or assigns and any entity in which Settling Defendants have or had a controlling interest.

The law firm of Robbins Geller Rudman & Dowd LLP represents you and other Class Members. You will not be charged for these lawyers. They will be paid from the Settlement Fund to the extent the Court approves their application for fees and expenses. If you want to be represented by your own lawyer, you may hire one at your own expense.

WHAT IS THIS LAWSUIT ABOUT?

As more fully described in the Notice of Proposed Settlement of Class Action (“Notice”), this is a securities class action asserting claims under Sections 11 and 15 of the Securities Act of 1933 (“Securities Act”) by making false and misleading statements and omissions to investors.  Settling Defendants deny all allegations of liability, fault, or wrongdoing whatsoever alleged in the Action. A settlement of the lawsuit has now been reached and is subject to approval by the Court. 

The Settlement provides that, in exchange for the release of the Released Plaintiff’s Claims (defined in the Notice) and dismissal of the Action, Settling Defendants have agreed to pay or cause to be paid $125 million in cash to be distributed after taxes, tax expenses, notice and claims administration expenses, and approved fees and expenses, pro rata, to Class Members who send in a valid Proof of Claim pursuant to the Court-approved Plan of Allocation. The Plan of Allocation is described in more detail at the end of the Notice.
