NOTE 9—STOCKHOLDERS’ EQUITY

In May 2017, the Company entered into an amended and restated sales agreement with Cowen and Company, LLC (“Cowen”) (the “ATM Facility”) pursuant to which the Company may offer and sell, in its sole discretion, shares of common stock having an aggregate offering price of up to $75.0 million through Cowen acting as the Company’s sales agent. Sales of the Company’s common stock, if any, will be made at market prices by any method that is deemed to be an “at the market offering” as defined in Rule 415 under the Securities Act of 1933, as amended. The Company has not sold any common stock under the ATM Facility. As of March 31, 2018, the full $75.0 million provided for under the ATM Facility remained available for sale, subject to certain conditions as specified in the agreement.
