Welcome to the website for In re Twitter, Inc. Securities Litigation, pending in the United States District Court for the Northern District of California (the “Action”).

The purpose of this website is to inform you of a class action lawsuit now pending in the United States District Court for the Northern District of California (the “Court”) against Twitter, Inc. (“Twitter” or the “Company”) and Individual Defendants Richard Costolo and Anthony Noto (collectively “Defendants”). The Notice of Pendency (“Notice”) is intended only to advise you that the Action has been certified by the Court to proceed as a class action on behalf of certain purchasers of Twitter common stock and your rights with respect to the lawsuit.

The Court has not decided whether Defendants did anything wrong, and the Notice is not an admission by Defendants or an expression of any opinion of the Court concerning the merits of the lawsuit, or a finding by the Court that the claims asserted by Co-Class Representatives KBC Asset Management NV (“KBC”) and National Elevator Industry Pension Fund (“National Elevator” and, together with KBC, “Co-Class Representatives”) in this case are valid. There is no settlement or monetary recovery at this time and there is no guarantee there will be any recovery. However, your legal rights are affected.

Subject to certain exclusions outlined in the Notice, the Class, certified by the Court, consists of:

All persons and entities that, during the period from February 6, 2015, through July 28, 2015, inclusive, purchased or otherwise acquired shares of the publicly traded common stock of Twitter, Inc., and were damaged thereby.
