  Note
  Heliogen, Inc. (the "Registrant") is
  filing this registration statement on Form S-8 (the "Registration Statement") with the Securities and Exchange Commission
  (the "SEC") to register the offering of an additional 9,646,223 shares of Common Stock, par value $0.0001 per share ("Common
  Stock"), of the Registrant. The 9,646,223 shares of Common Stock being registered herein include (i) 7,716,978 shares of Common
  Stock issuable pursuant to the Heliogen, Inc. 2021 Equity Incentive Plan (the "2021 EIP") and (ii) 1,929,245 shares of Common
  Stock issuable pursuant to the Heliogen, Inc. 2021 Employee Stock Purchase Plan (the "2021 ESPP"). These additional shares
  of Common Stock are securities of the same class as other securities for which an original registration statement on Form S-8 (File No.
  333-263346) was filed with the Commission on March 7, 2022 (the "Prior Registration Statement"). Accordingly, the contents
  of the Prior Registration Statement are incorporated by reference into this Registration Statement pursuant to General Instruction E of
  Form S-8. These additional shares of Class A Common Stock have become reserved for issuance as a result of the operation of the "evergreen"
  provisions in each of the 2021 EIP and 2021 ESPP, which provide that the total number of shares subject to such plan may be increased
  each year pursuant to a specified formula.
