This prospectus supplement supplements the prospectus, dated September 7, 2022 (the “Prospectus”), which forms a part of our registration statement on Form S-1 (No. 333-266763). This prospectus supplement is being filed to update and supplement the information in the Current Report on Form 8-K, filed with the Securities and Exchange Commission on October 25, 2022 (the “Current Report”). Accordingly, we have attached the Current Report to this prospectus supplement. The Prospectus and this prospectus supplement relate to the offer and resale of (i) up to 70,289,880 shares (the “CEF Shares”) of our common stock, $0.0001 per share (the “Common Stock”), by B. Riley Principal Capital II, LLC (the “B. Riley Principal Capital II”) and (ii) up to 386,697 shares (the “Advisory Fee Shares” and, together with the CEF Shares, the “Shares”) of Common Stock by B. Riley Securities, Inc. (“BRS” and, together with B. Riley Principal Capital II, the “Selling Stockholders”). The CEF Shares included in the Prospectus consist of shares of Common Stock that we have issued or that we may, in our discretion, elect to issue and sell to B. Riley Principal Capital II, from time to time after the date of the Prospectus, pursuant to a common stock purchase agreement we entered into with B. Riley Principal Capital II on July 20, 2022 (the “Purchase Agreement”), in which B. Riley Principal Capital II has committed to purchase from us, at our direction, up to $100,000,000 of shares of our Common Stock, subject to terms and conditions specified in the Purchase Agreement. Under the applicable Nasdaq rules, in no event may we issue to B. Riley Principal Capital II under the Purchase Agreement more than 70,289,880 shares of Common Stock, which number of shares is equal to approximately 19.99% of the shares of the Common Stock outstanding immediately prior to the execution of the Purchase Agreement (the “Exchange Cap”) unless certain conditions are met. Concurrently with our execution of the Purchase Agreement on July 20, 2022, we issued 573,381 shares of Common Stock, which are part of the CEF Shares included in the Prospectus, to B. Riley Principal Capital II as consideration for its irrevocable commitment to purchase shares of our Common Stock at our election in our sole discretion, from time to time after the date of the Prospectus, upon the terms and subject to the satisfaction of the conditions set forth in the Purchase Agreement. See the section titled “Committed Equity Financing” for a description of the Purchase Agreement and the section titled “Selling Stockholders” in the Prospectus for additional information regarding B. Riley Principal Capital II.

The Advisory Fee Shares included in the Prospectus consist of shares of Common Stock that we have issued to BRS as an advisory fee in connection with our execution of two amended and restated bridge promissory notes on August 1, 2022, one with B. Riley Commercial Capital, LLC and one with an affiliate of B. Riley Commercial Capital, LLC. Our Common Stock and Public Warrants are listed on the Nasdaq Global Select Market under the symbols “CORZ” and “CORZW,” respectively. On October 26, 2022, the last reported sales price of our Common Stock was $1.01 per share and the last reported sales price of our Public Warrants was $0.22 per warrant.
