Reverse Stock Split

On January 21, 2014, the board of directors and the stockholders of the Company approved a one-for-6.35 reverse stock split of the Company’s issued and outstanding common stock, which was effected on January 21, 2014. Stockholders entitled to fractional shares as a result of the reverse stock split received a cash payment in lieu of receiving fractional shares. The Company’s historical share and per share information related to issued and outstanding common stock and outstanding options and warrants exercisable for common stock have been retroactively adjusted to give effect to this reverse stock split. Shares of common stock underlying outstanding stock options and other equity instruments convertible into common stock were proportionately reduced and the respective exercise prices, if applicable, were proportionately increased in accordance with the terms of the agreements governing such securities.

Initial Public Offering

On February 11, 2014, the Company completed its IPO, whereby the Company sold 5,750,000 shares of its common stock (inclusive of 750,000 shares of common stock sold by the Company pursuant to the full exercise of an overallotment option granted to the underwriters in connection with the offering) at a price of $10.00 per share. The shares began trading on the Nasdaq Global Market on February 6, 2014. The aggregate net proceeds received by the Company from the offering were approximately $50.2 million, after deducting underwriting discounts and commissions and other offering expenses payable by the Company. Upon the closing of the IPO, all outstanding shares of convertible preferred stock converted into 8,260,444 shares of common stock; and warrants exercisable for convertible preferred stock were automatically converted into warrants exercisable for 30,708 shares of common stock, resulting in the reclassification of the related convertible preferred stock warrant liability to additional paid-in capital. Additionally, the Company is now authorized to issue 200,000,000 shares of common stock and 5,000,000 shares of preferred stock.
