On August 17, 2020, Analog Devices, Inc. (ADI) filed a registration statement on
Form S-4 (File No. 333-248092) (as amended, the Form S-4) with the Securities and Exchange
Commission (the SEC) in connection with ADIs proposed acquisition of Maxim Integrated Products, Inc. (Maxim) pursuant to an Agreement and Plan of Merger, dated as of July 12, 2020 (as it may be
amended from time to time, the Merger Agreement), by and among ADI, Magneto Corp., a wholly owned subsidiary of ADI (Acquisition Sub) and Maxim. On September 4, 2020, ADI filed with the SEC the definitive
joint proxy statement/prospectus relating to the special meeting of shareholders of ADI scheduled to be held on October 8, 2020 (the Definitive Proxy Statement) to, among other things, vote on a proposal to approve the
issuance of shares of ADI common stock to Maxim stockholders in connection with the merger.
Since the initial filing of the Form S-4, six complaints (collectively, the Maxim Stockholder Complaints), including two putative securities class action lawsuits, have been filed in federal courts in California, Delaware and New
York by purported Maxim stockholders against Maxim and the members of the Maxim board of directors in connection with the transactions contemplated by the Merger Agreement: Shiva Stein v. Maxim Integrated Products, Inc., et al., Case No. 5:20-cv-05830 (N.D. Cal., filed August 18, 2020); Joseph Post v. Maxim Integrated Products, Inc., et al., Case No. 1:99-mc-09999 (D. Del., filed August 24, 2020) (the Post Action); Waseem Khan v. Maxim Integrated Products, Inc., et al., Case No. 1:20-cv-03982 (E.D.N.Y., filed August 26, 2020); Joseph Burns v. Maxim Integrated Products, Inc., et al., No.
1:20-cv-07168 (S.D.N.Y., filed September 2, 2020); John Husselman v. Maxim Integrated Products, Inc., et al., Case No. 1:20-cv-07525 (S.D.N.Y., filed September 14, 2020); and Joseph Schaffer v. Maxim Integrated Products, Inc., et al., Case No. 5:20-cv-06816 (N.D. Cal., filed September 30, 2020). The Post Action
also names ADI and Acquisition Sub as defendants. In addition, one complaint, Coe Living Trust v. Analog Devices, Inc., et al., Case No. 1:20-cv-11682
(D. Mass., filed September 11, 2020), has been filed by a purported ADI shareholder in federal court in Massachusetts against ADI and the members of the ADI board of directors (the Coe Action and, together with the Maxim
Stockholder Complaints, the Federal Stockholder Complaints) and one derivative lawsuit has been filed against the members of the ADI board of directors in state court in the Commonwealth of Massachusetts (Mass. Sup. Ct., Norfolk
Cnty., Case No. 20-0864, filed September 11, 2020) (the ADI State Action and, together with the Federal Stockholder Complaints, the Stockholder Actions). Each of
the Federal Stockholder Complaints alleges, among other things, that the Form S-4 omits material information concerning the transactions contemplated by the Merger Agreement in violation of Sections 14(a) and
20(a) of the Securities Exchange Act of 1934, as amended (the Exchange Act), and Rule 14a-9 promulgated under the Exchange Act. The ADI State Action alleges breach of fiduciary duty claims
against ADIs directors in connection with the transactions contemplated by the Merger Agreement, including that the directors fraudulently concealed information based on allegations that the Form S-4
misrepresents or omits material information concerning the transactions contemplated by the Merger Agreement. The plaintiffs in the Federal Stockholder Complaints and the ADI State Action, among other things, seek to enjoin the transactions
contemplated by the Merger Agreement (and in two cases, to enjoin the shareholder vote) or, in the alternative, rescission of the merger or rescissionary damages, and an award of attorneys fees and expenses.
