Preferred Stock On October 30, 2020, the Company designated 1,000,000 shares as Series D Convertible Preferred Stock with a par value of $0.0001. On April 16, 2021, the Company closed on a private placement of 440,125 shares of Series D Convertible Preferred Stock (the “Preferred Stock”) with a par value of $0.0001, yielding gross proceeds of $6,551,691 (the “Private Placement”) and settlement of a $50,000 liability for Preferred Stock shares. The Private Placement proceeds will be used for working capital, primarily for the development, manufacturing and commercialization of 374Water’s Air SCWO systems. The Preferred Stock has a stated value of $15 per share, is convertible into common stock at $0.30 per share and has voting rights based on the underlying shares of common stock. Upon liquidation of the Company, the Preferred Stockholders have a liquidation preference before any assets can be distributed to common stockholders. All of the Preferred Stock were sold pursuant to an exemption from registration requirements under Regulation D and/or Section 4(2) of the Securities Act of 1933, as amended. On September 29, 2021, 412,853 shares of Series D Preferred stock were converted into 20,642,667 shares of common stock.

In the event of our liquidation or dissolution, holders of common stock are entitled to share ratably in all assets remaining after payment of liabilities and the liquidation preferences of any outstanding shares of preferred stock. Holders of common stock have no preemptive rights and have no right to convert their common stock into any other securities.
