Stockholders' Equity

Warrant exercise

In conjunction with the Company’s initial public offering on March 26, 2013, the underwriter received a warrant to acquire up to 140,000 units (“Unit Warrant”).  On March 23, 2016, the underwriter paid $1,008 to the Company to exercise the Unit Warrant. Each of the units delivered upon exercise consisted of one share of the Company’s common stock and one warrant to purchase one share of the Company’s common stock at an exercise price of $7.80 per share (“Warrant”), which warrant expired on March 27, 2018. On March 19, 2018, the underwriter paid $1,093 to the Company to exercise the Warrant. On March 21, 2018, the Company delivered 140,000 shares of common stock to the underwriter.

Common Stock offering

On August 9, 2018, the Company priced an underwritten follow-on offering of 1,270,000 shares of the Company’s common stock (the “2018 Firm Shares”) at an offering price of $79.00 per share. The shares were sold pursuant to an effective registration statement on Form S-3 (Registration No. 333-224392). In addition, a selling stockholder of the Company granted the underwriters of the offering a 30-day option to purchase up to 190,500 shares (the “2018 Option Shares”) of the Company’s common stock at the public offering price less the underwriting discount. On August 13, 2018, the Company closed on the 2018 Firm Shares, for which we received net proceeds of $93,469 after deducting the underwriting discount and estimated offering expenses payable by the Company, and the selling stockholder of the Company closed on the sale of all 2018 Option Shares. The Company did not receive any proceeds associated with the sale of the 2018 Option Shares by the selling stockholder.
