Preferred Stock

The Company’s initial certificate of incorporation authorized 5,000,000 shares of preferred stock, par value $0.001 per share. No preferred stock had been issued and outstanding since inception of the Company. In October 2016, the Company’s Board of Directors and a majority of the holders of the Company’s common stock approved an amendment and restatement of the certificate of incorporation which, in part, eliminated the authorized preferred stock. In August 2018, the Company’s Board of Directors approved a second amendment and restatement of the Company’s amended and restated certificate of incorporation (the “Amended and Restated Charter”) to, in part, increase the Company’s authorized capital to a total of 110.0 million shares, including 10.0 million shares of newly created preferred stock, par value $0.001 per share (“Preferred Stock”), authorize the Company’s Board of Directors to fix the designation and number of each series of Preferred Stock, and to determine or change the designation, relative rights, preferences, and limitations of any series of Preferred Stock. The Amended and Restated Charter was approved by a majority of the Company’s stockholders in September 2018, and was filed with the State of Delaware in November 2018. All references in the accompanying financial statements to Preferred Stock have been restated to reflect the Amended and Restated Charter.

Common Stock

The Amended and Restated Charter also increased the Company’s authorized capital to include 100.0 million shares of common stock, par value $0.001, and removed the deemed liquidation provision, as such term is defined in the Amended and Restated Charter. Each holder of common stock is entitled to one vote for each share of common stock held at all meetings of stockholders.
