Organization and Basis of Presentation

Zogenix, Inc. (the Company) is a pharmaceutical company committed to developing and commercializing therapies that address specific clinical needs for people living with pain-related conditions and central nervous system disorders who need innovative treatment alternatives to help them return to normal daily functioning. The Company’s first commercial product, Sumavel® DosePro® (sumatriptan injection) Needle-free Delivery System, was launched in January 2010. Sumavel DosePro offers fast-acting, easy-to-use, needle-free subcutaneous administration of sumatriptan for the acute treatment of migraine and cluster headache in a pre-filled, single-use delivery system. Sumavel DosePro is the first drug product approved by the U.S. Food and Drug Administration (FDA) that allows for the needle-free, subcutaneous delivery of medication. On October 25, 2013, the Company received FDA marketing approval for Zohydro™ ER (hydrocodone bitartrate) extended-release capsules, the first extended-release oral formulation of hydrocodone without acetaminophen. Zohydro ER is an opioid agonist for the management of pain severe enough to require daily, around-the-clock, long-term opioid treatment and for which alternative treatment options are inadequate. The Company launched Zohydro ER on March 3, 2014.

The Company was incorporated in the state of Delaware on May 11, 2006 as SJ2 Therapeutics, Inc. and commenced operations on August 25, 2006. On August 28, 2006, the Company changed its name to Zogenix, Inc.

The Company has incurred significant net losses since inception and has relied on its ability to fund its operations through equity financings, debt financings, revenues from the sale of its product Sumavel DosePro and proceeds from business collaborations. As the Company continues to incur losses, successful transition to profitability is dependent upon achieving a level of revenues adequate to support the Company’s cost structure. This may not occur and, unless and until it does, the Company will continue to need to raise additional cash. These conditions raise substantial doubt about the Company’s ability to continue as a going concern. The accompanying financial statements have been prepared assuming that the Company will continue as a going concern and do not include any adjustments that might result from the outcome of this uncertainty. This basis of accounting contemplates the recovery of the Company’s assets and the satisfaction of liabilities in the normal course of business.

On March 27, 2013, the Company entered into a controlled equity offering sales agreement (the sales agreement) with Cantor Fitzgerald & Co. (Cantor), as sales agent, under which the Company issued and sold shares of its common stock from time to time through Cantor, having an aggregate offering price of up to $25.0 million. The sales of common stock made under the sales agreement were made in “at-the-market” offerings as defined in Rule 415 of the Securities Act of 1933, as amended. Under the sales agreement, the Company issued 6,753,104 shares of its common stock during 2013 at an average stock issuance price of $1.66 per share, resulting in net proceeds of approximately $10,834,000. The sales agreement with Cantor terminated on November 16, 2013.

On November 12, 2013, the Company completed a public offering (the November 2013 Offering) of common stock for net proceeds of approximately $64,471,000 (including over-allotment purchase), after deducting underwriting discounts and commissions of $4,140,000 and offering expenses of approximately $389,000. The Company sold a total of 30,666,667 shares of its common stock (including the underwriters' over-allotment purchase of 4,000,000 shares) at a purchase price of $2.25 per share.

Management expects operating losses and negative cash flows to continue for at least the next year as the Company continues to incur costs related to the continued development of its product candidates and commercialization of its approved products. Management intends to pursue additional opportunities to raise additional capital, if required, through public or private equity offerings, including through debt financings, receivables financings or through collaborations or partnerships with other companies to further support its planned operations. There can be no assurance that the Company will be able to obtain any source of financing on acceptable terms, or at all. If the Company is unsuccessful in raising additional required funds, it may be required to significantly delay, reduce the scope of or eliminate one or more of its development programs or its commercialization efforts, or cease operating as a going concern. The Company also may be required to relinquish, license or otherwise dispose of rights to product candidates or products that it would otherwise seek to develop or commercialize itself on terms that are less favorable than might otherwise be available.
