Stockholders’ Equity

Initial Public Offering

On December 22, 2014, we completed our IPO in which we sold 11.5 million shares of our common stock to the public at $20 per share. We received net proceeds of $210.0 million from the IPO, net of underwriting discounts, commissions and offering expenses. Upon the closing of the IPO, all shares of outstanding redeemable convertible preferred stock automatically converted into shares of common stock and all warrants for redeemable convertible preferred stock converted to warrants for common stock.

Retroactive Stock Split

On November 26, 2014, we further amended our amended and restated certificate of incorporation effecting a 2-for-1 forward stock split of our common stock and redeemable convertible preferred stock. The stock split caused an adjustment to the par value of common and preferred stock, from $0.01 per share to $0.005 per share, and a doubling of the number of authorized and outstanding shares of such stock. As a result of the stock split, the share amounts under our employee incentive plan and warrant agreements with third parties were also adjusted accordingly. All numbers of shares and per share data in the accompanying consolidated financial statements and related notes have been retroactively adjusted to reflect this stock split for all periods presented.
