ZLTQ Zeltiq Aesthetics, Inc.

As previously disclosed on February 13, 2017, ZELTIQ Aesthetics, Inc., a Delaware corporation (the “Company”), entered into an Agreement and Plan of Merger (the “Merger Agreement”) with Allergan Holdco US, Inc., a Delaware corporation (“Parent”), and Blizzard Merger Sub, Inc., a Delaware corporation and a wholly owned subsidiary of Parent (the “Merger”). The Company is filing this Current Report on Form 8-K to provide certain updates in respect of the proposed Merger. The following information should be read in conjunction with the preliminary proxy statement relating to the proposed Merger (the “Proxy Statement”), filed by the Company with the Securities and Exchange Commission (the “SEC”) on March 9, 2017, which should be read in its entirety.

Litigation Relating to the Merger

On March 13, 2017, Michael Kreindler, a purported stockholder of the Company (the “Plaintiff”), filed a putative class action complaint against the Company and the members of the Company’s Board of Directors (the “Board”) in the United States District Court for the Northern District of California (the “District Court”). This case is captioned Kreindler v. Zeltiq Aesthetics, Inc. , Case No. 17-cv-1353. The complaint alleges that (1) the Company and the members of the Board violated Section 14(a) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), and Rule 14a-9 promulgated thereunder, by filing the Proxy Statement, which allegedly fails to disclose and/or misrepresents material information about the proposed Merger, and (2) the members of the Board, as control persons of the Company, violated Section 20(a) of the Exchange Act in connection with the filing of the allegedly materially deficient Proxy Statement. The Plaintiff has asked the District Court to, among other things, (i) declare the Proxy Statement is materially false or misleading, (ii) preliminarily and permanently enjoin the defendants from proceeding with the proposed Merger, and (ii) in the event the proposed Merger is consummated, rescind the proposed Merger or grant rescissory damages. The Company believes these claims are without merit and intends to vigorously defend this action. The Company cannot predict the outcome of or estimate the possible loss or range of loss from this matter. It is possible that additional, similar complaints may be filed or the complaint described above is amended. If this occurs, the Company does not intend to announce the filing of each additional, similar complaint or any amended complaint unless it contain allegations that are substantially distinct from those made in the pending action described above.

Cautionary Statement Regarding Forward-Looking Statements

This Current Report on Form 8-K contains forward-looking statements. Statements that are not historical facts, including statements about beliefs or expectations, are forward-looking statements. These statements are based on beliefs at the time the Company makes the statements, and readers should not place undue reliance on them. In some cases, readers can identify forward-looking statements by the use of forward-looking terms such as “may,” “will,” “intend,” “believes,” or the negative of these terms or other comparable terms. Forward-looking statements involve inherent risks and uncertainties, and the Company cautions readers that a number of important factors could cause actual results to differ materially from those contained in any such forward-looking statement. Factors that could cause actual results to differ materially from those described in this Current Report on Form 8-K include, among others: the occurrence of any event, change or other circumstances that could give rise to the termination of the Merger Agreement, the inability to complete the proposed Merger due to the failure to obtain stockholder approval for the proposed Merger, the failure to satisfy other conditions to completion of the proposed Merger, including that a governmental entity may prohibit, delay or refuse to grant approval for the consummation of the transaction or that the results of the litigation matter described herein, or any other litigation that may arise in the future, could prohibit or delay the proposed Merger. Additional risks are described in the Company’s Annual Report on Form 10-K for the year ended December 31, 2016, and its subsequently filed reports with the Securities and Exchange Commission (“SEC”). Readers are cautioned not to place undue reliance on the forward-looking statements included in this Current Report on Form 8-K, which speak only as of the date hereof.
