If You Purchased Facebook or Instagram Advertisements Between August 15, 2015, and October 27, 2021,

A Class Action Lawsuit May Affect Your Rights.

  • A lawsuit is pending in the United States District Court for the Northern District of California (the “Court”) against Meta Platforms, Inc. (“Facebook” or “Defendant”).
  • Plaintiffs in the lawsuit allege that Facebook made misrepresentations and omissions when providing the Potential Reach metric to advertisers. Plaintiffs allege Facebook inflated its potential advertising reach to consumers and charged artificially high premiums for ad placements. Facebook’s Potential Reach was expressed as a number of people. Plaintiffs allege that the Potential Reach metric was not actually an estimate of people, but an estimate of “accounts.” Plaintiffs allege that, because the number of unique accounts and unique people were different, this led to an inaccurate representation of how many people Class Members’ advertisements could reach. Plaintiffs allege that the discrepancy between people and accounts made the Potential Reach number inaccurate.
  • Facebook denies all of Plaintiffs’ allegations. While Facebook no longer provides Potential Reach estimates to advertisers, Facebook maintains that it provided accurate and informative disclosures about Potential Reach when it was available, including that it informed advertisers that despite Facebook’s efforts to deduplicate accounts, there were some users who had multiple accounts which may have impacted Potential Reach estimates. Facebook denies that any Class Member has been damaged. Facebook did not charge advertisers based on Potential Reach estimates but instead charged based on actual results which were provided in real time to advertisers. The Court has not made any determination as to who is right.
  • On March 29, 2022, the Court determined this case could proceed as a class action. This is not a determination about the merits of the claim, only that Plaintiffs may seek to prove their claims on behalf of the Class.
  • There is no money available now, and no guarantee there will be.

  • Your legal rights are affected, and your options are explained below. You have a choice to make now.

Your legal rights are affected whether you act or don’t act. Please read carefully.

YOUR LEGAL RIGHTS AND OPTIONS
Description Due Date

DO NOTHING

This option means that, if you are a Class Member, you remain part of the Class and you keep the possibility of getting money or benefits that may come from a trial or a settlement and will be bound by any judgment entered or settlement reached in the lawsuit, whether favorable or unfavorable. But you give up all rights to be part of any other lawsuit that asserts claims related to the allegations or claims against Facebook in this case.

EXCLUDE YOURSELF FROM THE CLASS

This option allows you to exclude yourself from the Class and retain the right to file a lawsuit against Facebook asserting claims relating to the allegations in this case. If you exclude yourself, you will not be bound by any judgment for or against Facebook and will not share in any money or benefits obtained for the Class. The exclusion deadline is July 28, 2025.

Class Definition—You May Be Part of the Class

The Court decided that members of the Class are defined as:

All United States residents (including natural persons and incorporated entities) who, from August 15, 2015, to October 27, 2021 (“Class Period”), paid for the placement of at least one advertisement on Facebook’s platforms, including the Facebook and Instagram platforms, which was purchased through Facebook’s Ads Manager or Power Editor.

The Case

Plaintiffs in the lawsuit allege that Facebook made misrepresentations and omissions when providing the Potential Reach metric to advertisers. Plaintiffs allege Facebook inflated its potential advertising reach to consumers and charged artificially high premiums for ad placements. Facebook’s Potential Reach was expressed as a number of people. Plaintiffs allege that Potential Reach metric was not actually an estimate of people, but an estimate of “accounts.” Plaintiffs allege that, because the number of unique accounts and unique people were different, this led to an inaccurate representation of how many people Class Members’ advertisements could reach. Plaintiffs allege that the discrepancy between people and accounts made the Potential Reach number inaccurate.

Plaintiffs bring claims for damages under California law for (1) fraudulent misrepresentation and (2) fraudulent concealment.

No money or benefits are available now because the case is not resolved. There is no guarantee that money or benefits will ever be obtained. If they are, you will be notified about how to ask for a share. If the litigation is resolved, and you have not excluded yourself pursuant to this Notice, you may not be given another opportunity to do so.

The Trial

Class Counsel will have to prove the Plaintiffs’ allegations at trial. The Court has scheduled a jury trial to begin on October 14, 2025. The trial will be held in the United States District Court, Northern District of California, located at Courtroom 11, 19th Floor, 450 Golden Gate Avenue, San Francisco CA 94102. During the trial, a Jury and the Judge will hear all the evidence to help them reach a decision whether Plaintiffs or Facebook is right about the allegations in the lawsuit. There is no guarantee that Plaintiffs will win or that they will be able to get money for all or some of the members of the Class.
