As previously disclosed, on January 18, 2022, Activision Blizzard, Inc., a Delaware corporation (the “Company” or “Activision Blizzard”), entered into an Agreement and Plan of Merger (the “Merger Agreement”), by and among the Company, Microsoft Corporation, a Washington corporation (“Parent” or “Microsoft”), and Anchorage Merger Sub Inc., a Delaware corporation and wholly owned subsidiary of Parent (“Merger Sub”). The Merger Agreement provides that, upon the terms and subject to the conditions set forth in the Merger Agreement, Merger Sub will merge with and into the Company (the “Merger”), with the Company surviving the Merger as a wholly owned subsidiary of Parent. The Company filed a definitive proxy statement (the “Proxy Statement”) with the Securities and Exchange Commission on March 21, 2022, in connection with, among other things, the Merger Agreement.

Certain Litigation

As previously disclosed in the Proxy Statement, following the announcement of the Merger and prior to the filing of the Proxy Statement, lawsuits were filed by purported stockholders of the Company in connection with the transactions contemplated by the Merger Agreement under the captions Stein v. Activision Blizzard, Inc. et al., No. 1:22-cv-01560 (S.D.N.Y.); Perry v. Activision Blizzard, Inc. et al., No. 1:22-cv-02074 (S.D.N.Y.); Whitfield v. Activision Blizzard, Inc. et al., 1:22-cv-01182 (E.D.N.Y.); Lande v. Activision Blizzard, Inc. et al., No. 1:22-cv-01267 (E.D.N.Y.); Watson v. Activision Blizzard, Inc. et al., No. 2:22-cv-01268 (C.D. Cal.); Rubin v. Activision Blizzard, Inc. et al., No. 2:22-cv-01343 (C.D. Cal.); Baker v. Activision Blizzard, Inc. et al., No. 2:22-cv-00875 (E.D. Pa.); and David v. Activision Blizzard, Inc. et al., No. 1:22-cv-00339 (D. Del.) (the “Complaints”). The Complaints each assert violations of Section 14(a) and Section 20(a) of the Securities Exchange Act of 1934, as amended, and allege that the preliminary proxy statement filed in connection with the Merger omitted certain purportedly material information which rendered the preliminary proxy statement incomplete and misleading. The Complaints name the Company and its directors as defendants.

Following the announcement of the Merger, the Company also received several demand letters from purported stockholders and one lawsuit, Sjunde AP-Fonden v. Activision Blizzard, Inc., No. 2022-0281-KSJM (Del. Ch.) (the “220 Complaint”), was filed for books and records pursuant to 8 Del. C. § 220. Among other things, the demand letters and the 220 Complaint seek to investigate purported breaches of fiduciary duty related to the Merger.

While the Company believes that the disclosures set forth in the Proxy Statement comply fully with all applicable law and denies the allegations in the Complaints, demand letters and the 220 Complaint, in order to moot plaintiffs’ disclosure claims, avoid nuisance and possible expense and business delays, and provide additional information to its stockholders, the Company has determined to voluntarily supplement certain disclosures in the Proxy Statement related to plaintiffs’ claims with the supplemental disclosures set forth below (the “Supplemental Disclosures”). Nothing in the Supplemental Disclosures shall be deemed an admission of the legal merit, necessity or materiality under applicable laws of any of the disclosures set forth herein. To the contrary, the Company specifically denies all allegations that any additional disclosure was or is required or material.
