EXPLANATORY NOTE

This Amendment No. 3 (this “Amendment No. 3”) to the Statement on Schedule 13D (as amended, the “Statement”) is being filed with the Securities and Exchange Commission (the “Commission”) relating to the common stock, par value $.0001 per share of Heliogen, Inc., a corporation organized under the laws of the state of Delaware (the “Issuer”). This Amendment amends and supplements the Statement originally filed on February 13, 2023 with the Commission. Unless otherwise defined herein, capitalized terms used herein shall have the meanings ascribed thereto in the Statement. Except as otherwise provided herein, each Item of the Schedule 13D remains unchanged.

Item 4.
Purpose of the Transaction.

Reporting Persons purchased the Shares based on their belief that the Shares, when purchased, constituted an attractive investment opportunity. The Reporting Persons were disappointed to learn that the Issuer’s Founder, Chairman and Chief Executive Officer (“CEO”), William Gross, was terminated by the board of directors of the Issuer (the “Board”) on February 5, 2023, and that the Board had appointed the Issuer’s then-serving Chief Financial Officer, Christiana Obiaya, as the Issuer’s CEO despite Ms. Obiaya not having any prior CEO experience. Upon reviewing the resignation letter from Mr. Gross, the Reporting Persons became concerned by the process that led to these recent Board decisions and engaged in discussions with the Board about shareholder representation in the boardroom.

On April 13, 2023, Continuum Renewables, Inc., a Delaware corporation (“CRI”), delivered to the Board a letter setting forth a non-binding proposal (the “Proposal”) for CRI to acquire all of the outstanding capital stock of the issuer for a purchase price of $0.40 per share of Common Stock in cash. PML Fund III is a significant investor in CRI.

On July 5, 2023, the board of directors of CRI resolved to terminate the consideration and pursuit of any proposal or plan to acquire all of the outstanding capital stock of the Issuer, including with respect to the Proposal set forth in a letter that CRI delivered to the Board on April 13, 2023, which was filed as Exhibit 99.2 and described in Item 4 to Amendment No. 1 to this Schedule 13D filed by the Reporting Persons with the Commission on April 13, 2023.

Each of the Reporting Persons reserves the right to formulate plans and/or proposals and to take such actions with respect to such Reporting Person’s investment in the Issuer, including any or all of the actions set forth in clauses (a) through (j) of Item 4 of Schedule 13D.  Depending on various factors including, without limitation, the price levels of the Shares, conditions in the securities markets, and general economic and industry conditions, the Reporting Persons may in the future take such actions with respect to their investment in the Issuer as they deem appropriate including, without limitation, disposing of some or all of Shares.

Item 5.
Interest in Securities of the Issuer.

The Reporting Persons have no intention to act together or with any other persons for the purpose of acquiring, holding, voting or disposing of equity securities of the Issuer. As a result of the resolution by the board of directors of CRI to terminate the consideration and pursuit of the Proposal, the Reporting Persons do not believe that they may be deemed to have formed a “group” within the meaning of Section 13(d)(3) of the Exchange Act, and Rule 13d-5(b)(1) thereunder, with William Gross, Idealab, a California corporation, Idealab Holdings, LLC, a Delaware corporation, and CRI (collectively, “Idealab”). The filing of this Amendment No. 3 shall not be deemed an admission that the Reporting Persons were members of a “group” for purposes of Section 13(d) of the Exchange Act.

SIGNATURE
