According to the law firm press release, Yahoo Inc, together with its subsidiaries, is a multinational technology company that provides a variety of internet services, including a web portal, search engine, Yahoo! Mail, Yahoo! News, Yahoo! Finance, advertising, and fantasy sports. As of February 2016, Yahoo had an estimated 1 billion monthly active users, roughly 280 million Yahoo! Mail users, and 205 million monthly unique visitors to its sites and services.

The Complaint alleges that throughout the Class Period, Defendants made materially false and/or misleading statements, as well as failed to disclose material adverse facts about the Company's business, operations, and prospects. Specifically, Defendants made false and/or misleading statements and/or failed to disclose that: (i) Yahoo failed to encrypt its users' personal information and/or failed to encrypt its users' personal data with an up-to-date and secure encryption scheme; (ii) consequently, sensitive personal account information from more than 1 billion users was vulnerable to theft; (iii) a data breach resulting in the theft of personal user data would foreseeably cause a significant drop in user engagement with Yahoo's websites and services; and (iv) as a result, Yahoo's public statements were materially false and misleading at all relevant times.

An amended Complaint was filed on June 7, 2017. A second amended Complaint was filed on February 2, 2018.

The parties entered into a Stipulation of Settlement on March 2, 2018. Certain Defendants filed a Motion to Dismiss the second amended Complaint on March 2. On April 16, the Court denied the Motion to Dismiss as moot. The Court issued an Order granting preliminary approval of the Settlement on May 9, 2018. On September 7, the Court granted final approval of the Settlement and entered Final Judgment. On January 26, 2020, the Court issued an Order granting Disbursement of the Settlement Funds.
