The information contained on this web page is only a summary of information presented in more detail in the Notice of Pendency and Proposed Settlement of Class Action (the “Notice”). Because this website is just a summary, you should review the Notice for additional details.

Plaintiff Has Reached a Proposed Settlement, Subject to Court Approval

The Court-appointed Lead Plaintiff, on behalf of itself and the Settlement Class, has reached a proposed settlement of this action, captioned Chester County Employees Retirement Fund v Alnylam Pharmaceuticals, Inc., et al., Index No. 655272/2019 (N.Y.S.C) (the “Action”), for a cash payment of $7,000,000 (the “Settlement”). The Settlement, if approved by the Court, will resolve all claims in this Action.

Your Rights in the Proposed Settlement

If you are a member of the Settlement Class, your rights will be affected and you may be eligible for a payment from the proceeds of the Settlement, if it receives final Court approval. The Class certified by the Court includes all persons or entities who purchased or otherwise acquired Alnylam common stock between November 14, 2017 and September 12, 2019, inclusive, except those persons or entities that are excluded, as described below.

You are not a Settlement Class Member if you are: (a) Defendants and their immediate families; (b) the officers, directors and affiliates of Defendants during the Settlement Class Period and members of their immediate families; (c) the legal representatives, heirs, successors, or assigns of any of the foregoing; (d) and any entity in which any Defendant has or had a controlling interest.  Also excluded from the Settlement Class is any person or entity who timely and validly requests exclusion from the Settlement Class as set forth in the Notice.

Please read the Notice to fully understand your rights and options. Copies of the Notice and Claim Form can be found in the menu at the top of this page.

If you are a member of the Settlement Class, in order to be potentially eligible to receive a payment from the Settlement, you must submit a Claim Form postmarked no later than March 17, 2022.

Payments to eligible claimants will be made only after the Settlement and a Plan of Allocation are approved by the Court and any appeals are resolved, and after the completion of all claims processing. Please be patient, as this process will take some time to complete.
