By filing this Current Report on Form 8-K and furnishing this information, Zogenix makes no admission as to the materiality of any information in this report. The information contained in this Current Report on Form 8-K is intended to be considered in the context of Zogenix’s filings with the SEC and other public announcements that Zogenix makes, by press release or otherwise, from time to time. Zogenix undertakes no duty or obligation to publicly update or revise the information contained in this report, although it may do so from time to time as its management believes is appropriate. Any such updating may be made through the filing of other reports or documents with the SEC, through press releases or through other public disclosure.

Zogenix cautions you that statements included in this Current Report on Form 8-K and the attached exhibit that are not a description of historical facts are forward-looking statements. These forward-looking statements include statements regarding: the ability to successfully commercialize Sumavel DosePro and its continued sales growth; the ability to obtain additional marketing approvals for Sumavel DosePro in the European Union; the timing of the release of Phase IV data for Sumavel DosePro; the potential for, and timing of, an NDA submission for ZX002 and IND submissions for Zogenix’s additional product candidates; the potential for ZX002 to be the first approved oral, single-entity controlled release formulation of hydrocodone; the completion of enrollment of one of the Phase 3 clinical trials for ZX002; the timing of results for the Phase 3 clinical trials for ZX002; the potential of co-promotion discussions for ZX002; the expansion of Zogenix’s existing sales team; the potential to broaden the application of the DosePro technology; and the potential market penetration of Sumavel DosePro and ZX002. The inclusion of forward-looking statements should not be regarded as a representation by Zogenix that any of its plans will be achieved. Actual results may differ from those set forth in this report due to the risk and uncertainties inherent in Zogenix’s business, including, without limitation: the market potential for migraine treatments, and Zogenix’s ability to compete within that market; inadequate therapeutic efficacy or unexpected adverse side effects relating to Sumavel DosePro that could delay or prevent commercialization, or that could result in recalls or product liability claims; Zogenix’s dependence on its collaboration with Astellas Pharma US, Inc. to promote Sumavel DosePro; the ability of Zogenix to ensure adequate and continued supply of Sumavel DosePro to successfully launch commercial sales or meet anticipated market demand; the progress and timing of Zogenix’s clinical trials; the potential that earlier clinical trials may not be predictive of future results; the potential for ZX002 to receive regulatory approval on a timely basis or at all; the potential for adverse safety findings relating to ZX002 to delay or prevent regulatory approval or commercialization; the ability of Zogenix and its licensors to obtain, maintain and successfully enforce adequate patent and other intellectual property protection of its products and product candidates and the ability to operate its business without infringing the intellectual property rights of others; and other risks described in Zogenix’s filings with the SEC. You are cautioned not to place undue reliance on these forward-looking statements, which speak only as of the date hereof. All forward-looking statements are qualified in their entirety by this cautionary statement and Zogenix undertakes no obligation to revise or update this report to reflect events or circumstances after the date hereof. This caution is made under the safe harbor provisions of Section 21E of the Exchange Act.
