DO NOTHING. |
Stay in the lawsuit. Await the outcome. Share in possible benefits. Give up certain rights. By doing nothing you are choosing to stay in the Class. You will be permitted to share in any recovery that may result from this class action, but you will give up your rights to sue Defendants in a separate lawsuit for any claims made in this action. In addition, you will be bound by past and any future court rulings on, or the settlement of, the claims against Defendants. |

ASK TO BE EXCLUDED FROM THE CLASS BY JULY 18, 2025. |
Get out of this lawsuit. If you opt out of the Class (meaning you say in writing that you do not want to be included in this lawsuit), you will not be entitled to any recovery that may result from this class action, but you will not be bound by any past or future rulings for or against Defendants. By excluding yourself from the Class, you could be time-barred from asserting the claims covered by this lawsuit by the applicable statutes of limitations or repose. You are encouraged to consult with a lawyer to determine whether any claims you wish to pursue would be barred by the applicable statutes of limitation or repose. |
What is this Lawsuit About?
The Action alleges that Defendants violated Section 10(b) of the federal Securities Exchange Act of 1934 (the “Exchange Act”) and Rule 10b-5 promulgated thereunder by making material misrepresentations and omissions concerning Acadia’s supplemental New Drug Application (“sNDA”) to expand the approved treatment indication for Acadia’s flagship drug, pimavanserin. Defendants deny all of these allegations, deny that they engaged in any wrongdoing, and deny that they have any liability or violated the Exchange Act.
How do I know if I am a Class Member?
You are a member of the Class if you acquired shares of Acadia common stock during the period from September 9, 2019 through April 4, 2021.
If you own interests in a mutual fund that acquired Acadia common shares, that does not make you a Class Member; instead, you are a Class Member only if you (or your broker on your behalf) acquired Acadia common shares for your own account. If you are the legal representative or fiduciary of a person or legal entity that acquired Acadia common shares (e.g., if you are the trustee of a trust that acquired Acadia common shares), then the person or entity that you represent will be the Class Member, but it may be legally bound by your decisions.
Is there any money available now?
No money or benefits are available in this Action now because the Court has not yet decided whether Defendants did anything wrong or have any liability, and the two sides have not settled the case. There is no guarantee that any money or benefits will ever be obtained. If they are, you will receive a notice describing how to receive a share of any recovery in which you may be eligible to participate.
