CAPSTONE TURBINE CORPORATION (NASDAQ:CPST) Files An 8-K Entry into a Material Definitive Agreement
Item 1.01. Entry into a Material Definitive Agreement.

On June7, 2018, Capstone Turbine Corporation (“we,” “us,” “Capstone” or the “Company”) entered into an At The Market Offering Agreement (the “Agreement”) with H.C. Wainwright& Co., LLC (“Wainwright” or the “Agent”), to create an at-the-market equity program under which the Company from time to time may offer and sell shares of its common stock, par value $0.001 per share, having an aggregate offering price of up to $25,000,000 (the “Shares”) through Wainwright.

Subject to the terms and conditions of the Agreement, Wainwright will use its commercially reasonable efforts to sell the Shares from time to time, based upon the Company’s instructions. The Company has provided the Agent with customary indemnification rights, and the Agent will be entitled to a commission at a fixed commission rate equal to 3.0% of the gross proceeds per Share sold.

Sales of the Shares, if any, under the Agreement may be made in transactions that are deemed to be “at the market offerings” as defined in Rule415 under the Securities Act of 1933, as amended (the “Securities Act”), including sales made by means of ordinary brokers’ transactions, including on the NASDAQ Capital Market, at market prices or as otherwise agreed with the Agent. The Company has no obligation to sell any of the Shares, and may at any time suspend offers under the Agreement or terminate the Agreement.
