3. To ratify the appointment by the audit committee of our board of directors of PricewaterhouseCoopers LLP as our independent registered public accounting firm for the year ending December 31, 2023;

QUESTIONS AND ANSWERS ABOUT THESE PROXY MATERIALS AND VOTING

We are providing you with these proxy materials because the Board of Directors of Heliogen, Inc. (the “Board”) is soliciting your proxy to vote at Heliogen’s 2023 Annual Meeting of Stockholders (the “Annual Meeting”), including at any adjournments or postponements thereof, to be held via a live audio webcast on August 3, 2023 at 8:00 a.m. Pacific Time. The Annual Meeting can be accessed virtually by visiting www.virtualshareholdermeeting.com/HLGN2023 where you will be able to listen to the meeting live, submit questions and vote online.

You are invited to attend the Annual Meeting to vote on the proposals described in this Proxy Statement. However, you do not need to attend the Annual Meeting to vote your shares. Instead, you may simply follow the instructions below to submit your proxy. The proxy materials, including this Proxy Statement and our Annual Report on Form 10-K for the year ended December 31, 2022 (the “2022 Annual Report”), are being distributed and made available on or about June 20, 2023. As used in this Proxy Statement, references to “we,” “us,” “our,” “Heliogen” and the “Company” refer to Heliogen, Inc. and its subsidiaries.

Why did I receive a Notice of Internet Availability of Proxy Materials regarding the availability of proxy materials on the internet instead of a full set of proxy materials?

Pursuant to rules adopted by the Securities and Exchange Commission (the “SEC”), we have elected to provide access to our proxy materials over the Internet. Accordingly, we have sent you a Notice of Internet Availability of Proxy Materials (the “Notice”) because the Board is soliciting your proxy to vote at the Annual Meeting, including at any adjournments or postponements of the meeting. All stockholders will have the ability to access the proxy materials on the website referred to in the Notice or request to receive a printed set of the proxy materials. Instructions on how to access the proxy materials over the Internet or to request a printed copy may be found in the Notice.

We intend to mail the Notice on or about June 20, 2023 to all stockholders of record entitled to vote at the Annual Meeting.

When and where is the Annual Meeting?

The Annual Meeting will be held virtually on Thursday, August 3, 2023, at 8:00 a.m. Pacific Time, via live audio webcast on the Internet. You may attend, vote and ask questions at the Annual Meeting by following the instructions provided on the Notice to log into www.virtualshareholdermeeting.com/HLGN2023. The Annual Meeting will be a virtual meeting, which will be conducted entirely online via audio webcast to allow greater participation. You will not be able to attend the Annual Meeting physically in person. You are entitled to attend the Annual Meeting if you were a stockholder of record as of June 7, 2023 (the “Record Date”). In order to participate in the Annual Meeting you must register to attend the meeting by 5:00 p.m., Eastern time, on August 2, 2023 using your control number from your Notice or if you received paper copies, your proxy card or voting instruction form. If you are a beneficial owner of shares registered in the name of your broker, bank or other agent, follow the instructions from your broker or bank.

The audio webcast of the Annual Meeting will begin promptly at 8:00 a.m. Pacific Time. We encourage you to access the meeting prior to the start time. Online check-in will begin at 7:45 a.m. Pacific Time, and you should allow reasonable time for the check-in procedures. Information on how to vote online during the Annual Meeting is discussed below.

Why is the Company holding the Annual Meeting virtually?

We are holding the Annual Meeting online and providing internet voting to facilitate stockholder attendance and participation by enabling all stockholders to participate fully, equally and without cost, using an Internet-connected device from any location around the world, with procedures designed to ensure the authenticity and correctness of your voting instructions. In addition, the virtual-only meeting format increases our ability to engage with all stockholders, regardless of size, resources or physical location. Heliogen stockholders will be afforded the same opportunities to participate at the virtual Annual Meeting as they would at an in-person Annual Meeting.

Where can I get technical assistance?

If you have difficulty accessing the meeting, please call the phone number listed at www.virtualshareholdermeeting.com/HLGN2023.

How do I ask a question at the Annual Meeting?

As part of the Annual Meeting, we will hold a question and answer session during which we intend to answer questions submitted prior to the meeting in accordance with the rules of conduct posted on the meeting website, as time permits. Only stockholders of record as of the Record Date who have registered in advance to attend the Annual Meeting may submit questions prior to the meeting that may be addressed during the Annual Meeting. If you would like to submit a question, you may do so when you register to attend the Annual Meeting at www.virtualshareholdermeeting.com/HLGN2023 using the control number provided in the Notice and typing your question in the appropriate box in the registration form.

In accordance with the rules of conduct, we ask that you limit your questions to one brief question that is relevant to the Annual Meeting and that such questions are respectful of your fellow stockholders and meeting participants. Questions and answers may be grouped by topic, and substantially similar questions may be grouped and answered once. In addition, questions may be ruled as out of order if they are, among other things, irrelevant to the business to be conducted at the Annual Meeting, related to pending or threatened litigation, disorderly, repetitious of statements already made, or in furtherance of the stockholder’s own personal, political or business interests.

Who can vote at the Annual Meeting?

Only stockholders of record at the close of business on the Record Date will be entitled to vote at the Annual Meeting. On the Record Date, there were 198,420,111 shares of common stock outstanding and entitled to vote.

What matters am I being asked to vote on?

There are four matters scheduled for a vote:

• The election of the two nominees for Class II directors named herein to serve until our 2026 annual meeting of stockholders and until their successors are duly elected and qualified, subject to their earlier death, resignation or removal (“Proposal 1”);

• The approval of an amendment to the Company’s second amended and restated certificate of incorporation (the “Certificate of Incorporation”) to effect a reverse stock split of our common stock, par value $0.0001 per share (the “Common Stock”) at a ratio in the range of one-for-ten to one-for-forty of our Common Stock, with the exact ratio to be determined in the discretion of the Board and with such reverse stock split to be effected at such time and date, if at all, as determined by the Board in its sole discretion (“Proposal 2” or the “Reverse Stock Split Proposal”);

• The ratification of the appointment by the Audit Committee of the Board (the “Audit Committee”) of PricewaterhouseCoopers LLP (“PwC”) as our independent registered public accounting firm for the year ending December 31, 2023 (“Proposal 3”); and

• The approval, on an advisory basis, of a proposal to adjourn the Annual Meeting, if necessary or appropriate, to solicit additional proxies if there are not sufficient votes at the time of the Annual Meeting to approve the Reverse Stock Split Proposal (“Proposal 4” or the “Adjournment Proposal”).

How does the Board recommend that I vote?

The Board recommends that you vote your shares of our Common Stock:

• “FOR” each of the two Class II director nominees named in this Proxy Statement;

• “FOR” the approval of the Reverse Stock Split Proposal;

Table of Contents

• “FOR” the ratification of the appointment of PwC as our independent registered public accounting firm for the year ending December 31, 2023; and

• “FOR” the approval, on an advisory basis, of the Adjournment Proposal.

How may I vote my shares?

The procedures for voting depend on whether your shares are registered in your name or are held by a bank, broker or other nominee:

Stockholder of Record: Shares Registered in Your Name

If, on June 7, 2023, your shares were registered directly in your name with Heliogen’s transfer agent, Continental Stock Transfer & Trust Company, then you are a stockholder of record. If you are a stockholder of record, you may vote your shares at the Annual Meeting by following the instructions provided on the Notice to log in to www.virtualshareholdermeeting.com/HLGN2023. You will be asked to provide the control number from your Notice. Whether or not you plan to attend the Annual Meeting, we urge you to vote by proxy to ensure your vote is counted. You may still attend and vote at the Annual Meeting even if you have already voted by proxy.

If you are a stockholder of record, you may vote by proxy over the telephone, vote by proxy through the Internet or vote by proxy using a proxy card that you may request or that we may elect to deliver at a later time:

• To vote using the proxy card that may have been delivered to you, simply complete, sign and date the proxy card and return it promptly in the envelope provided. If you return your signed proxy card to us before the Annual Meeting, we will vote your shares as you direct.

• To vote over the telephone, dial toll-free 1-800-690-6903 using a touch-tone phone and follow the recorded instructions. You will be asked to provide the control number from the Notice. Your vote must be received by 11:59 p.m. Eastern Time on August 2, 2023 to be counted.

• To vote through the internet, go to www.proxyvote.com to complete an electronic proxy card. You will be asked to provide the control number from your Notice. Your vote must be received by 11:59 p.m. Eastern Time on August 2, 2023 to be counted.

Beneficial Owner: Shares Registered in the Name of Broker or Bank

If, on June 7, 2023, your shares were held, not in your name, but rather in an account at a brokerage firm, bank, dealer or other similar organization, then you are the beneficial owner of shares held in “street name” and the Notice is being forwarded to you by that organization. The organization holding your account is the stockholder of record for purposes of voting at the Annual Meeting. As a beneficial owner, you have the right to direct your broker or other agent regarding how to vote the shares in your account. In addition to voting, you are also invited to attend the Annual Meeting. Follow the instructions from your broker or bank included with these proxy materials or contact your broker or bank for further information about how to direct your broker or other agent to vote or how to attend the Annual Meeting.

How many votes do I have?

On each matter to be voted upon, you have one vote for each share of common stock you own as of June 7, 2023.

Table of Contents

How many votes are needed to approve each proposal?

Proposal		Vote Required
Proposal 1:	Election of Directors	The affirmative vote of a plurality of the votes cast of the shares present in person, by remote communication, or represented by proxy and entitled to vote generally on the election of directors, meaning that the persons receiving the highest number of FOR votes, up to the total number of directors to be elected at the meeting, will be elected. There is no cumulative voting.
Proposal 2:	Approval of the Reverse Stock Split Proposal	The affirmative vote of the majority of the shares of outstanding Common Stock entitled to vote on the matter.
Proposal 3:	Ratification of the appointment of our independent registered public accounting firm	The affirmative vote of a majority in voting power of the shares present in person, by remote communication, or represented by proxy and entitled to vote on the matter.
Proposal 4:	Approval, on an advisory basis, of the Adjournment Proposal	The affirmative vote of a majority in voting power of the shares present in person, by remote communication, or represented by proxy and entitled to vote on the matter.

If I am a stockholder of record and I do not vote, or if I return a proxy card or otherwise vote without giving specific voting instructions, what happens?

If you are a stockholder of record and do not vote by completing your proxy card if you receive a paper copy of the proxy materials, by telephone, through the internet or online at the Annual Meeting, your shares will not be voted.

If you return a signed and dated proxy card or otherwise vote without marking voting selections, your shares will be voted “For” the election of each of the two nominees for director, “For” the approval of the Reverse Stock Split Proposal, “For” the ratification of the appointment of PwC as our independent registered public accounting firm for the year ending December 31, 2023, and “For” the approval, on an advisory basis, of the Adjournment Proposal. If any other matter is properly presented at the meeting, your proxyholder (one of the individuals named on your proxy card) will vote your shares using his or her best judgment.

If I am a beneficial owner of shares held in street name and I do not provide my broker or bank with voting instructions, what happens?

If you are a beneficial owner of shares held in street name and you do not instruct your broker, bank or other agent how to vote your shares, your broker, bank or other agent may still be able to vote your shares in its discretion. Under the rules of the New York Stock Exchange (“NYSE”), brokers, banks and other securities intermediaries that are subject to NYSE rules may use their discretion to vote your “uninstructed” shares with respect to matters considered to be “routine” under NYSE rules, but not with respect to “non-routine” matters. In this regard, Proposal 1 is considered to be “non-routine” under NYSE rules meaning that your broker may not vote your shares on those proposals in the absence of your voting instructions. However, Proposals 2 (approval of Reverse Stock Split Proposal), Proposal 3 (ratification of appointment of independent registered public accounting firm) and Proposal 4 (approval, on an advisory basis, of Adjournment Proposal) are considered to be “routine” matters under NYSE rules meaning that if you do not return voting instructions to your broker by its deadline, your shares may be voted by your broker in its discretion on Proposal 2, Proposal 3 and Proposal 4.

If you are a beneficial owner of shares held in street name, in order to ensure your shares are voted in the way you would prefer, you must provide voting instructions to your broker, bank or other agent by the deadline provided in the materials you receive from your broker, bank or other agent.

What are “broker non-votes”?

A “broker non-vote” occurs when your broker submits a proxy for the meeting with respect to “routine” matters but does not vote on “non-routine” matters because you did not provide voting instructions on these matters. These un-voted shares are counted as “broker non-votes.” Proposal 1 is considered to be “non-routine” under NYSE rules and we therefore expect broker non-votes to exist in connection with that proposal. Proposal 2, Proposal 3, and Proposal 4 are “routine” matters and therefore broker non-votes are not expected to exist in connection with these proposals.

Table of Contents

What are my choices for casting my vote on each matter to be voted on?

Your choices for casting your vote on each proposal to be voted on at the Annual Meeting are as follows:

Proposal	Voting Options	Effect of Abstentions	Broker Discretionary Voting Allowed?	Effect of Broker Non-Votes
Proposal 1: Election of Directors	“For” or “Withhold” with respect to each of the two director nominees	Not applicable.	No	None. Only votes “For” impact outcome. Withheld votes will have no effect.
Proposal 2: Approval of the Reverse Stock Split Proposal	“For,” “Against,” or “Abstain”	Vote “Against” the proposal	Yes	Not applicable
Proposal 3: Ratification of the Appointment of our Independent Registered Public Accounting Firm	“For,” “Against,” or “Abstain”	Vote “Against” the proposal	Yes	Not applicable
Proposal 4: Approval, on an Advisory Basis, of the Adjournment Proposal	“For,” “Against,” or “Abstain”	Vote “Against” the proposal	Yes	Not applicable

Can I change my vote after submitting my proxy?

Stockholder of Record: Shares Registered in Your Name

Yes. You can revoke your proxy at any time before the final vote at the meeting. If you are the record holder of your shares, you may revoke your proxy in any one of the following ways:

• You may submit another properly completed proxy card with a later date.

• You may grant a subsequent proxy by telephone or through the internet.

• You may send a timely written notice that you are revoking your proxy to Heliogen, Inc., Attn: General Counsel at 130 W. Union St., Pasadena, CA 91103. Such notice will be considered timely if it is received at the indicated address by the close of business on the business day one week preceding the date of the Annual Meeting.

• You may attend the Annual Meeting and vote online. Simply attending the meeting will not, by itself, revoke your proxy.

Your most current proxy card or telephone or internet proxy is the one that is counted.

Beneficial Owner: Shares Registered in the Name of Broker or Bank

If your shares are held by your broker, bank as a nominee or other agent, you should follow the instructions provided by your broker, bank or other agent.

How are votes counted?

Votes will be counted by the inspector of election appointed for the meeting, who will separately count, for the proposal to elect directors, votes “For,” “Withhold” and broker non-votes; and, with respect to the other proposals, votes “For” and “Against,” and abstentions. Abstentions are not applicable with respect to Proposal 1. Abstentions will have the same effect as “Against” votes for Proposal 2, Proposal 3 and Proposal 4. Broker non-votes on Proposal 1 will have no effect and will not be counted towards the vote total. Each of Proposal 2, Proposal 3 and Proposal 4 is considered

Table of Contents

a “routine” matter. Accordingly, if you hold your shares in street name and do not provide voting instructions to your broker, bank, or other agent that holds your shares, your broker, bank, or other agent has discretionary authority to vote your shares on Proposal 2, Proposal 3 and Proposal 4.

Who is paying for this proxy solicitation?

We will pay for the entire cost of soliciting proxies. In addition to these proxy materials, our directors and employees may also solicit proxies in person, by email, by telephone, or by other means of communication. Directors and employees will not be paid any additional compensation for soliciting proxies. We have also retained Morrow Sodali LLC as our “proxy solicitor” to assist in the solicitation of proxies. For these proxy solicitation services, Morrow Sodali LLC will receive an estimated fee of approximately $17,500 plus reasonable out-of-pocket expenses and fees for any additional services. We may also reimburse brokerage firms, banks and other agents for the cost of forwarding proxy materials to beneficial owners.

What does it mean if I receive more than one Notice?

If you receive more than one Notice, your shares may be registered in more than one name or in different accounts. Please follow the voting instructions on the Notices to ensure that all of your shares are voted.

What is the quorum requirement?

A quorum of stockholders is necessary to hold a valid meeting. A quorum will be present if stockholders holding a majority of the voting power of the outstanding shares entitled to vote are present in person, by remote communication, or represented by proxy at the meeting. On the Record Date, there were 198,420,111 shares outstanding and entitled to vote. Thus, the holders of 99,210,056 shares must be present by remote communication at the meeting or represented by proxy at the meeting to have a quorum.

Your shares will be counted towards the quorum only if you submit a valid proxy (or one is submitted on your behalf by your broker, bank or other nominee) or if you vote by telephone, online or at the meeting. Abstentions and broker non-votes will be counted towards the quorum requirement. If there is no quorum, the holders of a majority of the voting power of the shares present by remote communication at the meeting or represented by proxy and entitled to vote may adjourn the meeting to another date.

Will a list of record stockholders as of the Record Date be available?

A list of our record stockholders as of the close of business on the Record Date will be made available to stockholders for the ten days ending the day prior to the Annual Meeting. The list will be available for examination by any stockholder of record for any purpose germane to the Annual Meeting at our corporate headquarters during normal business hours.

What if another matter is properly brought before the meeting?

The Board knows of no other matters that will be presented for consideration at the Annual Meeting. If any other matters are properly brought before the meeting, it is the intention of the persons named in the accompanying proxy to vote on those matters in accordance with their best judgment.

How can I find out the results of the voting at the Annual Meeting?

Preliminary voting results will be announced at the Annual Meeting. In addition, final voting results will be published in a current report on Form 8-K that we expect to file within four business days after the Annual Meeting. If final voting results are not available to us in time to file a Form 8-K within four business days after the meeting, we intend to file a Form 8-K to publish preliminary results and, within four business days after the final results are known to us, file an additional Form 8-K to publish the final results.

PROPOSAL NO. 1
ELECTION OF DIRECTORS

Our Board is divided into three classes, designated as Class I, Class II and Class III, each of which has a three-year term. Vacancies on the Board may be filled only by persons elected by a majority of the remaining directors. A director elected by the Board to fill a vacancy in a class, including vacancies created by an increase in the number of directors, shall serve for the remainder of the full term of that class and until the director’s successor is duly elected and qualified.

Our Board presently has eight members. There are two directors in the class whose term of office expires in 2023. Stacey Abrams is currently a director who was previously elected by the stockholders. Barbara Burger is currently a director. Dr. Burger was introduced to our Board by Bill Gross, our former Chief Executive Officer and was appointed to the Board upon the recommendation of the Board’s nominating and corporate governance committee (the “Nominating Committee”). If elected at the Annual Meeting, each of these nominees would serve until the 2026 annual meeting of stockholders and until his or her successor has been duly elected and qualified, or, if sooner, until the director’s death, resignation or removal.

Directors are elected by the affirmative vote of a plurality of the votes of the shares present in person, by remote communication, or represented by proxy and entitled to vote generally on the election of directors. Accordingly, the two nominees receiving the highest number of affirmative votes will be elected. Shares represented by executed proxies will be voted, if authority to do so is not withheld, for the election of the two nominees named below. If any nominee becomes unavailable for election as a result of an unexpected occurrence, shares that would have been voted for that nominee will instead be voted for the election of a substitute nominee proposed by us. Each person nominated for election has agreed to serve if elected. Our management has no reason to believe that any nominee will be unable to serve.

The following is a brief biography of each nominee and each director whose term will continue after the Annual Meeting if re-elected.

INFORMATION REGARDING THE BOARD OF
DIRECTORS AND CORPORATE GOVERNANCE

Corporate Governance Guidelines

Our Board has documented our governance practices by adopting Corporate Governance Guidelines to assure that the Board will have the necessary authority and practices in place to review and evaluate our business operations as needed and to make decisions that are independent of our management. The guidelines are also intended to align the interests of directors and management with those of our stockholders. The Corporate Governance Guidelines set forth the practices the Board intends to follow with respect to board composition and selection, board meetings and involvement of senior management, Chief Executive Officer performance evaluation and succession planning, and board committees and compensation. Our Corporate Governance Guidelines may be viewed at investors.heliogen.com.

Annual Board Evaluation

Pursuant to our Corporate Governance Guidelines and the charter of the Nominating Committee, the Nominating Committee oversees a periodic evaluation, which we expect to occur annually, of the performance of the Board and each of its committees in order to assess the overall effectiveness of the Board and its committees. The evaluation process is designed to facilitate ongoing, systematic examination of the Board’s effectiveness and accountability, and to identify opportunities for improving its operations and procedures. The effectiveness of individual directors is considered each year when the directors stand for re-nomination.

Director Independence

As required under the NYSE listing standards, a majority of the members of a listed company’s board of directors must qualify as “independent,” as affirmatively determined by the board of directors. Our Board consults with the Company’s counsel to ensure that the Board’s determinations are consistent with relevant securities and other laws and regulations regarding the definition of “independent,” including those set forth in pertinent listing standards of the NYSE, as in effect from time to time.

Consistent with these considerations, after review of all relevant identified transactions or relationships between each director, or any of his or her family members, and the Company, its senior management and its independent auditors, the Board has affirmatively determined that the following directors are independent directors within the meaning of the applicable NYSE listing standards: Ms. Newhouse, Mr. Padmanathan, Ms. Abrams, Dr. Burger, Mr. Kavner, Ms. Kane and Mr. Lazarus. The Board also had determined that Mr. David Crane, who served as a director until September 5, 2022, was an independent director within the meaning of the applicable NYSE listing standards. In making these determinations, the Board considered the current and prior relationships that each non-employee director has with our company and all other facts and circumstances our board of directors deemed relevant in determining their independence and found that none of these directors or nominees for director had a material or other disqualifying relationship with the Company.

Our independent directors meet in executive session without management present if circumstances warrant when the full Board convenes for a regularly scheduled meeting or a special meeting. The independent directors at such executive sessions shall designate an independent director to preside over the executive session.

Family Relationships

There are no family relationships among the directors and executive officers.

Board Leadership Structure

Our Corporate Governance Guidelines provide that the Board will exercise its discretion in combining or separating the offices of the chairperson of the Board and the Chief Executive Officer, based on the Board’s judgment of the best interests of the Company and its stockholders from time to time. Our Corporate Governance Guidelines provide that if the chairperson of the Board is not an independent director, the independent directors will appoint from among themselves an independent director to serve as Lead Independent Director.

Table of Contents

On February 5, 2023, our Board terminated Mr. Gross as our Chief Executive Officer and, on the same date, Mr. Gross resigned as the chairperson of our Board. The Board then appointed Ms. Obiaya as our Chief Executive Officer and Ms. Kane as the chairperson of the Board. Prior to Mr. Gross’s departure, Mr. Kavner served as the Lead Independent Director.

Prior to Mr. Gross’s departure, the Board determined to combine the positions of Chief Executive Officer and chairperson to ensure that the Board and management acted with a common purpose. The Board believed that combining the positions of Chief Executive Officer and chairperson helped to provide a single, clear chain of command to execute our strategic initiatives and business plans. While Mr. Gross served as chairperson, our Board appointed Mr. Kavner as the lead independent director to help reinforce the independence of the Board as a whole. Mr. Kavner was empowered to, among other duties and responsibilities, approve agendas and meeting schedules for regular Board meetings, preside over Board meetings in the absence of the chairperson, preside over and establish the agendas for meetings of the independent directors, act as liaison between the chairperson and the independent directors, approve information sent to the Board, preside over any portions of Board meetings at which the evaluation or compensation of the Chief Executive Officer is presented or discussed and, as appropriate upon request, act as a liaison to stockholders.

After Mr. Gross’s departure, the Board determined to separate the roles of chairperson of the Board and Chief Executive Officer. The Board determined that separation of the positions of chairperson of the Board and Chief Executive Officer reinforces the independence of the Board in its oversight of the business and affairs of the Company. In addition, the Board believes that having an independent chairperson of the Board creates an environment that is more conducive to objective evaluation and oversight of management’s performance, increasing management accountability and improving the ability of the Board to monitor whether management’s actions are in the best interests of the Company and its stockholders. As a result, the Company believes that having an independent Board chairperson can enhance the effectiveness of the Board as a whole. In addition, the Board believes that participation of the Chief Executive Officer as a director, while keeping the roles of Chief Executive Officer and chairperson of the Board separate, provides the proper balance between independence and management participation at this time.

Role of the Board in Risk Oversight

The Board believes that effective risk management involves our entire corporate governance framework. Both management and the Board have key responsibilities in managing risk throughout the Company. One of the Board’s key functions is informed oversight of the company’s risk management process. In particular, our Board is responsible for monitoring and assessing strategic risk exposure, including a determination of the nature and level of risk appropriate for the Company. Our Board does not have a standing risk management committee, but rather administers this oversight function directly through the Board as a whole, as well as through various Board standing committees that address risks inherent in their respective areas of oversight, as further detailed in the table below. In fulfilling this oversight role, our Board focuses on understanding the nature of our enterprise risks, including our operations and strategic direction, as well as the adequacy of our risk management process and overall risk management system. Our Board and standing committees perform these functions in a number of ways, including the following:

Board Responsibilities

• Overall oversight concerning the assessment and management of risk related to our business, including risks related to environmental, social and governance practices, and financial, legal and operational risks

• Decision-making for fundamental financial and business strategies and major corporate activities, including material acquisitions and financings

Meetings of the Board of Directors and Attendance

Our Board met 12 times during the last fiscal year. Each Board member attended 75% or more of the aggregate number of meetings of the Board and the committees of the Board on which they served, except for Ms. Abrams. Ms. Abrams attended more than 75% of the Board meetings, but was unable to attend three meetings of the Nominating Committee because of scheduling conflicts with prior commitments relating to Ms. Abrams’ campaign for governor of the State of Georgia. In addition, we encourage all of our directors and nominees for director to attend our annual meeting of stockholders, but attendance is not mandatory. Each of the directors serving at the date of our 2022 annual meeting of stockholders attended the meeting.

Each of the committees has authority to engage legal counsel or other experts or consultants, as it deems appropriate to carry out its responsibilities. Our Board has determined that other than Ms. Obiaya, who is a member of the Corporate Strategy Committee, each member of each committee meets the applicable NYSE rules and regulations regarding “independence” and each member is free of any relationship that would impair his or her individual exercise of independent judgment with regard to us.

Audit Committee

Our Audit Committee is currently composed of three directors: Mr. Kavner, Mr. Lazarus and Ms. Newhouse. The chair of the Audit Committee is Mr. Kavner. The Audit Committee did not meet during the prior fiscal year. The Board has adopted a written Audit Committee charter that is available to stockholders on the Company’s website at investors.Heliogen.com.

The primary purpose of our Audit Committee is to discharge the responsibilities of our board of directors with respect to our corporate accounting and financial reporting processes, systems of internal control and financial statement audits, and to oversee our independent registered public accounting firm. Specific responsibilities of the Audit Committee include:

• overseeing the Company’s accounting and financial reporting processes, systems of internal control, financial statement audits and the integrity of the Company’s financial statements;

• managing the selection, engagement terms, fees, qualifications, independence, and performance of the registered public accounting firms engaged as the Company’s independent outside auditors for the purpose of preparing or issuing an audit report or performing audit services;

• reviewing any reports or disclosures required by applicable law and stock exchange listing requirements;

Table of Contents

• overseeing the design, implementation, organization and performance of the Company’s internal audit function;

• helping the Board oversee the Company’s legal and regulatory compliance, including risk assessment and management practices and policies;

• providing regular reports and information to the Board.

Our Board reviews the NYSE listing standards definition of independence for Audit Committee members on an annual basis and has determined that all members of the Audit Committee are independent (as independence is currently defined in Section 303A.07(a) of the NYSE Listed Company Manual and Rule 10A-3(b)(1) of the Exchange Act).

Our Board has determined that each of Mr. Kavner and Mr. Lazarus is an “audit committee financial expert” within the meaning of SEC regulations. Each member of the Audit Committee can read and understand fundamental financial statements in accordance with applicable requirements. In arriving at these determinations, the Board examined each audit committee member’s scope of experience and the nature of their employment.

Compensation Committee

Our Compensation Committee is composed of three directors: Dr. Burger, Ms. Newhouse and Mr. Lazarus. The chair of the Compensation Committee is Ms. Newhouse. Our Board has determined that each member of our Compensation Committee is independent under the listing standards of the NYSE, and a “non-employee director” as defined in Rule 16b-3 promulgated under the Exchange Act. Our Board has adopted a written Compensation Committee charter that is available to stockholders on our website at investors.Heliogen.com.

The primary purpose of our Compensation Committee is to discharge the responsibilities of our Board in overseeing our compensation policies, plans, and programs, and to review and determine the compensation to be paid to our executive officers, directors, and other senior management, as appropriate. Specific responsibilities of our Compensation Committee include:

• helping the Board oversee the Company’s compensation policies, plans and programs with a goal to attract, incentivize, retain and reward top quality executive management and employees;

• reviewing and determining the compensation to be paid to the Company’s executive officers and directors;

• when required, reviewing and discussing with management the Company’s compensation disclosures in the “Compensation Discussion and Analysis” section of the Company’s annual reports, registration statements, proxy statements or information statements filed with the SEC;

• when required, preparing and reviewing the Compensation Committee report on executive compensation included in the Company’s annual proxy statement in accordance with applicable rules and regulations of the SEC in effect from time to time; and

• reviewing the human capital management practices related to the Company’s talent generally (including how the Company recruits, develops, and retains people).

Compensation Committee Processes and Procedures

Our Compensation Committee expects to meet regularly and in executive session as desired. However, from time to time, the Compensation Committee may invite to its meetings any director, officer or employee of the Company and such other persons as it deems appropriate in order to carry out its responsibilities. Our Chief Executive Officer may not participate in, or be present during, any deliberations or determinations of the Compensation Committee regarding her compensation or performance. In addition, under the charter, the Compensation Committee has the authority to obtain, at the expense of the Company, advice and assistance from compensation consultants and internal and external legal or other advisors and other external resources that the Compensation Committee considers necessary or appropriate in the performance of its duties. The Compensation Committee has direct responsibility for the compensation and oversight of the work of any consultants or advisers engaged for the purpose of advising the Compensation Committee. In particular, the Compensation Committee has the sole authority to retain, in its sole discretion, compensation consultants to assist in its evaluation of executive and director compensation, including the authority to approve the consultant’s reasonable fees and other retention terms. Under the charter, the Compensation

Table of Contents

Committee may select, or receive advice from, a compensation consultant, legal counsel or other adviser to the Compensation Committee, other than in-house legal counsel and certain other types of advisers, only after taking into consideration factors prescribed by the SEC and NYSE, that bear upon the adviser’s independence; however, there is no requirement that any adviser be independent.

Our Compensation Committee typically makes most of the significant adjustments to annual compensation, and determines base salary, bonus and equity awards at one or more meetings held during the first quarter of its fiscal year. However, our Compensation Committee also considers matters related to individual compensation, such as compensation for new executive hires, as well as high-level strategic issues, such as the efficacy of our compensation strategy, potential modifications to that strategy and new trends, plans or approaches to compensation, at various meetings throughout the year. Our Compensation Committee recommends to the independent members of the Board for determination and approval the compensation and other terms of employment of our Chief Executive Officer and evaluates the Chief Executive Officer’s performance in light of relevant corporate performance goals and objectives. For all executives and directors as part of its deliberations, our Compensation Committee may review and consider, as appropriate, materials such as financial reports and projections, operational data, tax and accounting information, tally sheets that set forth the total compensation that may become payable to executives in various hypothetical scenarios, executive and director stock ownership information, our stock performance data, analyses of historical executive compensation levels and current Company-wide compensation levels. In May 2022, our Compensation Committee engaged the services of Clearbridge Compensation Group LLC (“Clearbridge”), a compensation consulting firm, to advise the Compensation Committee regarding the amount and types of compensation that we provide to our executives and directors and how our compensation practices compare to the compensation practices of other selected companies. Clearbridge does not provide any services to us other than the services provided to the Compensation Committee. The Compensation Committee believes that Clearbridge does not have any conflicts of interest in advising the Compensation Committee under applicable SEC rules or NYSE listing standards. The Compensation Committee has assessed the independence of Clearbridge pursuant to SEC rules and NYSE listing standards and concluded that no conflict of interest exists that would prevent Clearbridge from independently representing the committee.

Compensation Committee Interlocks and Insider Participation

None of the members of our Compensation Committee has ever been one of our executive officers or employees. None of our executive officers currently serve, or has served during the last completed fiscal year, on the compensation committee or board of directors of any other entity that has one or more executive officers that serve as a member of the Board or Compensation Committee.

Nominating and Corporate Governance Committee

Our Nominating Committee is composed of three directors: Ms. Kane, Mr. Kavner and -Ms. Abrams. The chair of the Nominating Committee is Ms. Abrams. Our Board has determined that each member of the Nominating Committee is independent under the listing standards of the NYSE. Our Board has adopted a written Nominating Committee charter that is available to stockholders on the Company’s website at investors.Heliogen.com.

Specific responsibilities of the Nominating Committee include:

• helping the Board oversee the Company’s corporate governance functions and develop, update as necessary and recommend to the Board the governance principles applicable to the Company;

• identifying, evaluating and recommending and communicating with candidates qualified to become Board members or nominees for directors of the Board consistent with criteria approved by the Board;

• reviewing candidates nominated by stockholders;

• recommending the composition, functions, and duties of the committees of the Board;

• overseeing and monitoring the Company’s corporate governance policies and initiatives, including its environmental and sustainability policies and initiatives, and risks related to the Company’s operations, supply chain, and customer engagement;

Table of Contents

• annually overseeing an evaluation of the performance of the Board, including the Board committees, and, as appropriate, making recommendations to the Board for areas of improvement; and

• making other recommendations to the Board relating to the directors of the Company.

Our Nominating Committee uses a variety of methods to identify and evaluate director nominees. In its evaluation of director candidates, the Nominating Committee considers the current size and composition, organization, and governance of the Board and the needs of the Board and the respective committees of the Board, as well as a candidate’s potential conflicts of interest or other commitments. Some of the qualifications that the Nominating Committee considers include, without limitation, business experience, diversity, professional background, education, skill and other individual qualities and attributes that contribute to the total mix of viewpoints and experience represented on the Board. Nominees must be of high character and integrity. Members of the Board are expected to prepare for, attend, and participate in all Board and applicable committee meetings. The Nominating Committee may also consider such other factors as it may deem, from time to time, are in the Company’s and its stockholders’ best interests.

Although we do not maintain a specific policy with respect to board diversity, the Board believes that the Board should be a diverse body, and the Nominating Committee considers a broad range of backgrounds and experiences. In making determinations regarding nominations of directors, the Nominating Committee may take into account the benefits of diverse viewpoints. Our Nominating Committee also considers applicable laws and regulations, including monitoring proposed and enacted legislation. After completing its review and evaluation of director candidates, the Nominating Committee recommends to the Board the director nominees for selection.

Director Candidates Recommended by Stockholders

Our Nominating Committee will consider director candidates recommended by stockholders in accordance with our policy regarding stockholder recommendations of director nominees. Properly communicated stockholder-recommended director candidates will be considered in the same manner and using the same criteria as used for any other director candidate. To be properly communicated, stockholders desiring to recommend candidates for consideration by the Nominating Committee and the Board should submit their recommendation in writing to the attention of the Secretary, Heliogen, Inc., 130 W. Union St., Pasadena, CA 91103, together with the following information: (i) a completed written questionnaire (in a form provided by Heliogen) with respect to the background, qualifications, stock ownership and independence of such proposed nominee, and such additional information with respect to such proposed nominee as would be required to be disclosed in a proxy statement soliciting proxies for the election of such nominee as a director in an election contest (even if an election contest is not involved), or that is otherwise required to be disclosed pursuant to Section 14 of the 1934 Act and the rules and regulations promulgated thereunder, (ii) a written representation and agreement (in a form provided by Heliogen) that such nominee (a) if elected as director of Heliogen, intends to serve the entire term until the next meeting at which such nominee would face re-election and (b) consents to being named as a nominee in Heliogen’s proxy statement pursuant to Rule 14a-4(d) under the 1934 Act and any associated proxy card of Heliogen and agrees to serve if elected as a director, (iii) a statement whether such nominee, if elected, intends to tender, promptly following such person’s failure to receive the required vote for election or re-election at the next meeting at which such person would face election or re-election, an irrevocable resignation effective upon acceptance of such resignation by the Board, and (iv) all the information about the stockholder and the candidate that would be required pursuant to Article III, Section 5 of our Bylaws if the stockholder was nominating the candidate for election to the Board. The Nominating Committee may request additional information concerning such director candidate as it deems reasonably required to determine the eligibility and qualification of the director candidate to serve as a member of the Board.

Please note that stockholders who wish to nominate a person for election as a director (including nominations subject to Rule 14a-19 under the Exchange Act) in connection with an annual meeting of stockholders (as opposed to making a recommendation to the Nominating Committee as described above) must deliver written notice to our Secretary in the manner described in Article III, Section 5 of our Bylaws, and as described further under “Proposals of Stockholders and Director Nominations for 2024 Annual Meeting.”

Stockholder Communications with the Board of Directors

Our relationship with our stockholders is an important part of our corporate governance program. Engaging with stockholders helps us to understand how they view us, to set goals and expectations for our performance, and to identify emerging issues that may affect our strategies, corporate governance, compensation practices or other

Table of Contents

aspects of our operations. Our stockholder and investor outreach includes investor road shows, analyst meetings, and investor conferences and meetings. We also communicate with stockholders and other stakeholders through various media, including our annual report and SEC filings, proxy statement, news releases and our website. Our webcasts for quarterly earnings releases are open to all. These webcasts are available in real time and are archived on our website for a period of time.

Interested parties wishing to communicate with non-management members of our Board may do so by writing and mailing the correspondence to Secretary, Heliogen, Inc., 130 W. Union St., Pasadena, CA 91103. Each communication should set forth (i) the name and address of the stockholder, as it appears on our books, and if the shares of our common stock are held by a nominee, the name and address of the beneficial owner of such shares, and (ii) the class and number of shares of our common stock that are owned of record by the record holder and beneficially by the beneficial owner. The Secretary will review all incoming communications and, if appropriate, such communications will be forwarded to the appropriate member or members of our Board, or if none are specified, to the chairperson of our Board. Communications are distributed to our Board, or to any individual director as appropriate depending on the facts and circumstances outlined in the communication. The purpose of this screening is to allow our Board to avoid having to consider irrelevant or inappropriate communications (such as advertisements, solicitations and hostile communications). Communications determined by the Secretary to be inappropriate for presentation will still be made available to any non-management member of our Board upon such member’s request. The screening procedures have been approved by a majority of the independent directors. Every effort has been made to ensure that the views of stockholders are heard by our Board or individual directors, as applicable, and that appropriate responses are provided to stockholders in a timely manner.

Code of Conduct

We have adopted the Heliogen, Inc. Code of Conduct that applies to all officers, directors and employees. The Code of Conduct is available on our website at investors.heliogen.com. If we make any substantive amendments to the Code of Conduct or grant any waiver from a provision of it to any executive officer or director, we will promptly disclose the nature of the amendment or waiver on our website at investors.heliogen.com to the extent required by applicable rules and exchange requirements.

Hedging Policy

Our Insider Trading Policy prohibits directors, officers, including our named executive officers, and certain other employees of the Company from engaging in hedging or monetization transactions, including through the use of financial instruments such as prepaid variable forwards, equity swaps, collars and exchange funds. Our Insider Trading Policy also prohibits trading in derivative securities related to the Company’s common stock, which include publicly-traded call and put options (other than employee options and other equity awards granted under our equity compensation plans), as well purchasing our common stock on margin or holding our common stock in margin accounts.

Environmental, Social and Governance

In addition to our existing environmental compliance initiatives, we will also be engaging additional resources to focus on a broader Environmental, Social and Governance (“ESG”) program across our business. As part of our commitment to energy sustainability, we completed an ESG assessment during 2022 to develop a baseline against which to prioritize our ESG strategies.

PROPOSAL NO. 2
THE REVERSE STOCK SPLIT PROPOSAL

Our Board has approved, and is recommending that our stockholders approve, proposed amendments to our Certificate of Incorporation to effect a reverse stock split (the “Reverse Stock Split”) of all of the issued and outstanding shares of our Common Stock at a ratio of between one-for-ten (1:10) and one-for-forty (1:40)(inclusive), with such ratio to be determined at the sole discretion of our Board and with such Reverse Stock Split to be effected at such time and date, if at all, as determined by our Board in its sole discretion. The text of the proposed form of Certificate of Amendment to our Certificate of Incorporation (the “Certificate of Amendment”) to effect the Reverse Stock Split is attached as Appendix A to this Proxy Statement. However, the text of the proposed amendments is subject to revision to include such changes as may be required by the Secretary of State of the State of Delaware and as our Board deems necessary or advisable to effect the proposed amendment of our Certificate of Incorporation.

By approving this proposal, stockholders will approve a series of amendments to our Certificate of Incorporation pursuant to which any whole number of outstanding shares between and including ten and forty would be combined into one share of our Common Stock, and authorize our Board to file only one such amendment, as determined by our Board in the manner described herein, and to abandon each amendment not selected by the Board. Our Board believes that stockholder approval of amendments granting our Board this discretion, rather than approval of a specified stock split ratio, provides our Board with maximum flexibility to react to then-current market conditions and, therefore, is in the best interests of the Company and its stockholders. Our Board may effect only one Reverse Stock Split as a result of this authorization. Our Board may also elect not to do any Reverse Stock Split. The Reverse Stock Split will take effect, if at all, only after it is (i) approved by the affirmative vote of a majority of the shares of outstanding Common Stock entitled to vote on the matter, (ii) is deemed by the Board to be in the best interests of the Company and its stockholders, and (iii) after filing the amendment to our Certificate of Incorporation with the Secretary of State of the State of Delaware. If the Certificate of Amendment is filed with the Secretary of State of the State of Delaware, the Certificate of Amendment will effect the Reverse Stock Split by reducing the outstanding number of shares of the Common Stock by the ratio to be determined by the Board, but will not increase the par value of the Common Stock, and will not change the number of authorized shares of the Common Stock. If the Board does not implement an approved Reverse Stock Split prior to the one-year anniversary of this meeting, the Board will seek stockholder approval before implementing any Reverse Stock Split after that time.

You should keep in mind that the implementation of a reverse stock split does not have an effect on the intrinsic value of our business or your proportional ownership in it. You should also consider that in many cases, the market price of a company’s common stock may decline following a reverse stock split.

Background

Our Common Stock is currently listed on the NYSE under the symbol “HLGN.” In order for our Common Stock to continue to be listed on the NYSE, we must satisfy various listing maintenance standards established by the NYSE. If we are unable to meet the NYSE requirements, our Common Stock will be subject to delisting.

Under Section 802.01C of the NYSE Listed Company Manual (“Section 802.01C”), if the average closing price of our Common Stock is under $1.00 per share over a period of 30 consecutive trading days and does not thereafter reach at least $1.00 per share and an average closing price of at least $1.00 over the 30 trading-day period ending on the last trading day of any month during the applicable grace period following notification by the NYSE, the NYSE may delist our Common Stock from trading.

On December 23, 2022, the NYSE notified us that the average closing price of our Common Stock had fallen below the required $1.00 per share over a period of 30 consecutive trading days (the “Minimum Share Price Notice”), and, accordingly, that we did not comply with Section 802.01C. We have six months following receipt of the Minimum Share Price Notice to regain compliance with the price requirement, unless it is necessary to take an action that requires stockholder approval, in which case we must obtain such approve no later than the date of the Annual Meeting, with the possibility of an extension at the discretion of the NYSE. Accordingly, our Board adopted resolutions, subject to approval by our stockholders, to amend our Certificate of Incorporation to effect a Reverse Stock Split of our Common Stock at a ratio in the range of one-for-ten to one-for-forty, such ratio to be determined in the discretion of our Board. These resolutions were approved as a means of increasing the share price of our Common Stock above $1.00, which is required for continued listing on the NYSE.

Reasons for the Proposed Reverse Stock Split

The Board’s primary objective in proposing the Reverse Stock Split is to raise the per share trading price of our Common Stock. The Board believes that the Reverse Stock Split will result in a higher per share trading price, which is intended to enable us to maintain the listing of our Common Stock on the NYSE and generate greater investor interest in the Company.

The Board believes that maintaining the listing of our Common Stock on the NYSE is in the best interests of the Company and our stockholders. If our Common Stock were delisted from the NYSE, the Board believes that such delisting would adversely affect the market liquidity of our Common Stock, decrease the market price of our Common Stock, adversely affect our ability to obtain financing for the continuation of our operations and result in the loss of confidence in our company.

If the Reverse Stock Split is approved by our stockholders and implemented by the Board, we expect to satisfy the $1.00 per share minimum closing price requirement for continued listing. However, despite the approval of the Reverse Stock Split by our stockholders and implementation by the Board, there can be no assurance that the Reverse Stock Split will result in our meeting and maintaining the $1.00 minimum closing price requirement. The effect of the Reverse Stock Split upon the market price for our Common Stock cannot be predicted, and the history of similar reverse stock splits for companies in like circumstances is varied. The market price per share of our Common Stock after the Reverse Stock Split may not rise in proportion to the reduction in the number of shares of our Common Stock outstanding resulting from the Reverse Stock Split due to, among other reasons, our performance and other factors that may be unrelated to the number of shares outstanding. Our Common Stock could also be delisted from the NYSE due to our failure to comply with one or more other NYSE listing standards. Although we have submitted to the NYSE a plan to regain compliance with Section 802.01C, we cannot be certain that we will ultimately be able to regain compliance with this listing standard.

Our Board also believes that the expected increased market price per share of our Common Stock as a result of implementing a Reverse Stock Split could improve the marketability and liquidity of our Common Stock and encourage interest and trading in our Common Stock. We understand that many brokerage houses, institutional investors and funds have internal policies and practices that either prohibit them from investing in low-priced stocks or tend to discourage individual brokers from recommending low-priced stocks to their customers or by restricting or limiting the ability to purchase such stocks on margin. Some of those policies and practices may make the processing of trades in low-priced stocks economically unattractive to brokers. Additionally, a Reverse Stock Split could help increase analyst and broker interest in our Common Stock as their internal policies might discourage them from following or recommending companies with low stock prices. Investors may also be dissuaded from purchasing stocks below certain prices because brokers’ commissions, as a percentage of the total transaction value, can be higher for low-priced stocks.

Criteria to be Used for Determining Whether to Implement Reverse Stock Split

In determining whether to implement the Reverse Stock Split and which Reverse Stock Split ratio to implement, if any, following receipt of stockholder approval of this Proposal 2, our Board may consider, among other things, various factors, such as:

• the historical trading price and trading volume of our Common Stock;

• the then-prevailing trading price and trading volume of our Common Stock and the expected impact of the Reverse Stock Split on the trading market for our Common Stock in the short- and long-term;

• the continued listing requirements for our Common Stock on the NYSE;

• which Reverse Stock Split ratio would result in the least administrative cost to us; and

• prevailing general market and economic conditions.

The failure of our stockholders to approve this Proposal 2 could have serious, adverse effects on us and our stockholders. We could be delisted from the NYSE because shares of Common Stock may continue to trade below the requisite $1.00 per share bid price needed to maintain our listing. If the NYSE delists the Common Stock, our shares may then trade on the OTC Bulletin Board or other small trading markets, such as the pink sheets. In that event, the Common Stock could trade thinly as a microcap or penny stock, adversely decrease to nominal levels of trading and be avoided by retail and institutional investors, resulting in the impaired liquidity of our shares.

Table of Contents

Our Board reserves the right to abandon the Reverse Stock Split without further action by our stockholders at any time before the effectiveness of our Certificate of Amendment, even if the Reverse Stock Split has been authorized by our stockholders. By voting in favor of the Reverse Stock Split, you are expressly authorizing our Board to determine not to proceed with, and abandon, the Reverse Stock Split if it should so decide.

Effect on Outstanding Common Stock and Authorized Common Stock

After the effective date of any Reverse Stock Split that our Board elects to implement, each stockholder will own a reduced number of shares of Common Stock. The Reverse Stock Split will be effected simultaneously for all issued and outstanding shares of Common Stock and the Reverse Stock Split ratio will be the same for all issued and outstanding shares of Common Stock. Any Reverse Stock Split will affect all of our stockholders uniformly and will not affect any stockholder’s percentage ownership interests in the Company, except to the extent that the Reverse Stock Split results in any of our stockholders owning a fractional share as described below. Voting rights and other rights and preferences of the holders of the Common Stock will not be affected by a Reverse Stock Split (other than as a result of the payment of cash in lieu of fractional shares). For example, a holder of 2% of the voting power of the outstanding shares of Common Stock immediately prior to a Reverse Stock Split would continue to hold 2% of the voting power of the outstanding shares of Common Stock immediately after such Reverse Stock Split. The number of stockholders of record will not be affected by a Reverse Stock Split (except to the extent that any stockholder holds only a fractional share interest and receives cash for such interest after such Reverse Stock Split).

The following table illustrates the effects of a one-for-ten, one-for-fifteen, one-for-twenty, one-for-twenty five, one-for-thirty, one-for-thirty five and one-for-forty Reverse Stock Split on our outstanding Common Stock as of June 1, 2023 (without giving effect to any adjustments for fractional shares):

Reverse Split Ratio	Approximate Number of Shares Issued and Outstanding	Number of Shares Authorized	Percentage of Authorized Common Stock
Current Shares	198,299,649	500,000,000	39.7	%
1-for-10	19,829,964	500,000,000	3.96	%
1-for-15	13,219,976	500,000,000	2.64	%
1-for-20	9,914,982	500,000,000	1.98	%
1-for-25	7,931,986	500,000,000	1.59	%
1-for-30	6,609,988	500,000,000	1.32	%
1-for-35	5,665,704	500,000,000	1.13	%
1-for-40	4,957,491	500,000,000	0.99	%

The amendment will not change the terms of our Common Stock. The shares of new Common Stock will have the same voting rights and rights to dividends and distributions and will be identical in all other respects to the Common Stock now authorized. The Common Stock issued pursuant to the Reverse Stock Split will remain fully paid and non-assessable. The Reverse Stock Split is not intended as, and will not have the effect of, a “going private transaction” covered by Rule 13e-3 under the Exchange Act. We will continue to be subject to the periodic reporting requirements of the Exchange Act.

We are currently authorized to issue up to 500,000,000 shares of Common Stock under our Certificate of Incorporation. The Reverse Stock Split will have no effect on the total number of shares of Common Stock we are authorized to issue under our Certificate of Incorporation. Therefore, upon effectiveness of the Reverse Stock Split, the number of shares of Common Stock that are authorized and unissued will increase relative to the number of issued and outstanding shares. We may use the additional authorized and unissued shares of Common Stock resulting from the Reverse Stock Split to issue additional shares of Common Stock from time to time in equity financings, under our equity compensation plans or in connection with other matters. The Board currently has no plans, arrangements or understandings regarding the issuance of such additional authorized and unissued shares of Common Stock.

As of the Record Date, there were no issued or outstanding shares of our preferred stock and no outstanding options or warrants to purchase shares of our preferred stock. The Reverse Stock Split will not impact the number of authorized shares of our preferred stock.

Effect on Outstanding Equity Awards

If the Reverse Stock Split is implemented, the number of shares of Common Stock subject to outstanding options and restricted stock units (“RSUs”) issued by the Company, and the number of shares reserved for future issuance under the Company’s 2021 Equity Incentive Plan (the “2021 Plan”) and the Company’s 2021 Employee Stock Purchase Plan (the “2021 ESPP”), will be reduced by the same ratio as the reduction in the outstanding shares. Correspondingly, the exercise price for individual outstanding options, on a per share basis, will be proportionally increased (i.e., the aggregate exercise price for all outstanding options will be unaffected, but following a Reverse Stock Split such exercise price will apply to a reduced number of shares). As of June 7, 2023, there were outstanding (i) stock options to purchase an aggregate of 17,284,101 shares of Common Stock at a weighted average exercise price of $1.67 per share, and (ii) RSUs representing the right to acquire an aggregate of 17,098,657 shares of Common Stock. Assuming, for example, a 1-for-30 Reverse Stock Split, the number of shares covered by outstanding options and RSUs will be reduced to one-thirtieth the number currently issuable, and the exercise price of outstanding options will be increased by 30 times the current exercise price.

Effect on Warrants

If the Reverse Stock Split is implemented, the number of shares of Common Stock issuable upon the exercise of our outstanding warrants, will be reduced by the same ratio as the reduction in the outstanding shares. Correspondingly, the exercise price for individual warrants, on a per share basis, will be proportionally increased (i.e., the aggregate exercise price for all outstanding warrants will be unaffected, but following a Reverse Stock Split such exercise price will apply to a reduced number of shares). As of June 7, 2023, there were outstanding warrants to purchase an aggregate of 13,205,623 shares of Common Stock at a weighted average exercise price of $7.46 per share. Assuming, for example, a 1-for-30 Reverse Stock Split, the number of shares covered by outstanding warrants will be reduced to one-thirtieth the number currently issuable, and the exercise price of outstanding warrants be increased by 30 times the current exercise price.

Effect on Rights Agreement

On April 16, 2023, our Board declared a dividend of one preferred share purchase right (“Right”) for each outstanding share of our Common Stock to the stockholders of record as of the close of business on April 28, 2023 and adopted a limited duration stockholder rights plan (the “Rights Agreement”). Each Right entitles the holder thereof to purchase for $3.50 (the “Purchase Price”), one one-thousandth of a share of our Series A Junior Participating Preferred Stock (the “Series A Preferred Stock”) in the event (a) an Acquiring Person (as defined in the Rights Agreement) acquires beneficial ownership of 12.5% (20% in the case of certain passive institutional investors) or more of the outstanding shares of our Common Stock or (b) an Acquiring Person announces a tender or exchange offer, the consummation of which would result in ownership by an Acquiring Person of 12.5% (20% in the case of certain passive institutional investors) or more of the outstanding shares of our Common Stock. The Rights Agreement contains adjustment provisions such that in the case of the Reverse Stock Split, (a) the number of one one-thousandth of a share of Series A Preferred Stock purchasable following the Reverse Stock Split upon proper exercise of each Right is the number of one one-thousandth of a share of Series A Preferred Stock so purchasable immediately prior to the Reverse Stock Split multiplied by a fraction, the numerator of which is the number of shares of Common Stock outstanding immediately prior to the Reverse Stock Split and the denominator of which is the number of shares of Common Stock outstanding immediately following the Reverse Stock Split, (b) each share of Common Stock outstanding immediately following the Reverse Stock Split will have issued with respect to it that number of Rights that a share of Common Stock outstanding immediately prior to the Reverse Stock Split had issued with respect to it, and (c) the Purchase Price immediately prior to the effective date for the Reverse Stock Split will be adjusted so that the Purchase Price following the Reverse Stock Split is the Purchase Price in effect immediately prior to the Reverse Stock Split multiplied by a fraction, the numerator of which is the number of shares of Common Stock outstanding immediately prior to the Reverse Stock Split and the denominator of which is the number of shares of Common Stock outstanding immediately following the Reverse Stock Split.. The description and terms of the Rights are set forth in the Rights Agreement.

Table of Contents

Cash Payment in Lieu of Fractional Shares

No fractional shares of Common Stock will be issued in connection with the Reverse Stock Split. If as a result of the Reverse Stock Split, a stockholder of record would otherwise hold a fractional share, the stockholder will receive a cash payment in lieu of the issuance of any such fractional share in an amount per share equal to the closing price per share on the NYSE on the trading day immediately preceding the effective date of the Reverse Stock Split (as adjusted to give effect to the Reverse Stock Split), without interest. The ownership of a fractional interest will not give the holder thereof any voting, dividend or other right except to receive the cash payment therefore.

By approving the amendment to our Certificate of Incorporation effecting the Reverse Stock Split, stockholders will be approving the combination of any whole number of issued shares of our Common Stock between and including 10 and 40 shares into one share of Common Stock.

Stockholders should be aware that, under the escheat laws of the various jurisdictions where stockholders reside, where we are domiciled and where the funds will be deposited, sums due for fractional interests that are not timely claimed after the effective time may be required to be paid to the designated agent for each such jurisdiction. Thereafter, stockholders otherwise entitled to receive such funds may have to seek to obtain them directly from the state to which they were paid.

Accounting Matters

The par value of the shares of our Common Stock is not changing as a result of the implementation of the Reverse Stock Split. Our stated capital, which consists of the par value per share of our Common Stock multiplied by the aggregate number of shares of our Common Stock issued and outstanding, will be reduced proportionately on the effective date of the Reverse Stock Split. Correspondingly, our additional paid-in capital, which consists of the difference between our stated capital and the aggregate amount paid to us upon the issuance of all currently outstanding shares of our Common Stock, will be increased by a number equal to the decrease in stated capital. Further, net loss per share, book value per share and other per share amounts will be increased as a result of the Reverse Stock Split because there will be fewer shares of Common Stock outstanding.

Possible Disadvantages of Reverse Stock Split

Even though the Board believes that the potential advantages of the Reverse Stock Split outweigh any disadvantages that might result, the following are some of the possible disadvantages of the Reverse Stock Split:

• The reduced number of outstanding shares of our Common Stock resulting from the Reverse Stock Split could adversely affect the liquidity of our Common Stock.

• Based on the experience of certain other companies that have effected reverse stock splits, the Reverse Stock Split could result in a devaluation of our market capitalization and the trading price of our Common Stock, on an actual or an as-adjusted basis.

• The Reverse Stock Split may leave certain stockholders with one or more “odd lots,” which are stock holdings in amounts of less than 100 shares of our Common Stock. These odd lots may be more difficult to sell than shares of Common Stock in even multiples of 100. Additionally, any reduction in brokerage commissions resulting from the Reverse Stock Split, as discussed above, may be offset, in whole or in part, by increased brokerage commissions required to be paid by stockholders selling odd lots created by the Reverse Stock Split.

• There can be no assurance that the market price per new share of our Common Stock after the Reverse Stock Split will increase in proportion to the reduction in the number of old shares of our Common Stock outstanding before the Reverse Stock Split. The effect of the Reverse Stock Split upon the market price of the Common Stock cannot be predicted with any certainty, and the history of similar reverse stock splits for companies in like circumstances is varied, particularly since some investors may view a reverse stock split negatively. For example, based on the closing market price of our Common Stock on June 7, 2023 of $0.24 per share of Common Stock, if the stockholders approve this proposal and the Board selects

Table of Contents

and implements a Reverse Stock Split ratio of 1-for-40, there can be no assurance that the post-split market price of our Common Stock would be $9.60 per share or greater. Accordingly, the total market capitalization of our Common Stock after the proposed Reverse Stock Split may be lower than the total market capitalization before the proposed Reverse Stock Split and, in the future, the market price of our Common Stock following the Reverse Stock Split may not exceed or remain higher than the market price prior to the proposed Reverse Stock Split.

• While the Board believes that a higher stock price may help generate investor interest, there can be no assurance that the Reverse Stock Split will result in a per share price that will attract institutional investors or investment funds or that such share price will satisfy the investing guidelines of institutional investors or investment funds. As a result, the trading liquidity of our Common Stock may not necessarily improve.

• If the Reverse Stock Split is effected and the market price of our Common Stock declines, the percentage decline may be greater than would occur in the absence of a Reverse Stock Split. The market price of our Common Stock will, however, also be based on our performance and other factors, which are unrelated to the number of shares outstanding.

• The implementation of the Reverse Stock Split will effectively result in an increase in the authorized number of shares of Common Stock relative to the number of shares outstanding, which could, under certain circumstances, have anti-takeover implications by permitting issuances that would dilute the ownership of a person seeking to effect a hostile takeover or increase its percentage ownership. This Proposal 2 has been prompted by business and financial considerations and not by the threat of any hostile takeover attempt.

Procedure for Effecting Reverse Stock Split and Exchange of Stock Certificates

If our stockholders approve the Reverse Stock Split, the Reverse Stock Split would become effective at such time as it is deemed by our Board to be in the best interests of the Company and its stockholders and we file the amendment to our Certificate of Incorporation with the Secretary of State of the State of Delaware. Even if the Reverse Stock Split is approved by our stockholders, our Board has discretion not to carry out or to delay in carrying out the Reverse Stock Split. Upon the filing of the amendment, all the old Common Stock will be converted into new Common Stock as set forth in the amendment.

As soon as practicable after the effective time of the Reverse Stock Split, stockholders will be notified that the Reverse Stock Split has been effected. If you hold shares of Common Stock in a book-entry form, your shares will be exchanged automatically into post-split shares without further action by you as soon as practicable after the effective time of the Reverse Stock Split.

Some stockholders hold their shares of Common Stock in certificate form or a combination of certificate and book-entry form. We expect that our transfer agent will act as exchange agent for purposes of implementing the exchange of stock certificates, if applicable. If you are a stockholder holding pre-split shares in certificate form, you will receive a transmittal letter from our transfer agent as soon as practicable after the effective time of the Reverse Stock Split. The transmittal letter will be accompanied by instructions specifying how you can exchange your certificate representing the pre-split shares of our Common Stock for a statement of holding. When you submit your certificate representing the pre-split shares of our Common Stock, your post-split shares of our Common Stock will be held electronically in book-entry form in the Direct Registration System. This means that, instead of receiving a new stock certificate, you will receive a statement of holding that indicates the number of post-split shares you own in book-entry form. We will no longer issue physical stock certificates unless you make a specific request for a share certificate representing your post-Reverse Stock Split ownership interest.

STOCKHOLDERS SHOULD NOT DESTROY ANY STOCK CERTIFICATE(S) AND SHOULD NOT SUBMIT ANY CERTIFICATE(S) UNTIL REQUESTED TO DO SO.

Beginning on the effective time of the Reverse Stock Split, each certificate representing pre-Reverse Stock Split shares will be deemed for all corporate purposes to evidence ownership of post-Reverse Stock Split shares. If a stockholder is entitled to a payment in lieu of any fractional share interest, such payment will be made as described above under “No Fractional Shares.”

Table of Contents

Criteria to be Used for Decision to Apply the Reverse Stock Split

In the event that approval for the Reverse Stock Split is obtained, our Board will be authorized to proceed with the Reverse Stock Split. If on the last trading day of any calendar month prior to the Annual Meeting our stock has a closing share price of at least $1.00 and an average closing share price of at least $1.00 over the 30 trading-day period ending on the last trading day of that month, our Board may delay its decision to execute the Reverse Stock Split indefinitely. In that case, if at any time during the 12-month period following the Annual Meeting the stock price falls below $1.00 on the last trading day of any calendar month or has an average closing share price below $1.00 over the 30 trading-day period ending on the last trading day of that month and therefore fails to comply with the applicable NYSE minimum listing standards, then the Reverse Stock Split may be executed as a cure for this condition.

No Appraisal Rights

Under the General Corporation Law of the State of Delaware, our stockholders are not entitled to dissenter’s or appraisal rights with respect to our proposed amendment to our Certificate of Incorporation to effect the Reverse Stock Split and we will not independently provide our stockholders with any such right.

Certain Material U.S. Federal Income Tax Consequences of the Reverse Stock Split to U.S. Holders

The following is a summary of certain material U.S. federal income tax consequences of the Reverse Stock Split that generally are expected to be applicable to U.S. Holders (as defined below) of our Common Stock who hold their common shares, both before and after the Reverse Stock Split, as capital assets within the meaning of Section 1221 of Internal Revenue Code of 1986, as amended (the “Code”) (generally property held for investment). This summary is based on provisions of the Code, applicable Treasury Regulations promulgated thereunder, judicial authority and current administrative rulings and practices as in effect on the date of this proxy statement. Changes to these laws could alter the tax consequences described below, possibly with retroactive effect, which may result in the U.S. federal income tax consequences of the Reverse Stock Split differing substantially from the consequences summarized below. We have not sought and will not seek an opinion of counsel or a ruling from the Internal Revenue Service regarding the U.S. federal income tax consequences of the Reverse Stock Split and there can be no assurance that the Internal Revenue Service or the courts will accept the positions expressed below.

This discussion is for general information only and does not purport to consider all aspects of U.S. federal income taxation that might be relevant to a U.S. Holder. This discussion does not address the tax consequences which may apply to stockholders subject to special rules, such as financial institutions, insurance companies, tax-exempt organizations, dealers in securities, real estate investment trusts, regulated investment companies, stockholders who hold their pre-Reverse Stock Split shares through individual retirement or other tax-deferred accounts, stockholders who are not U.S. Holders (as defined below), stockholders who have a functional currency other than the U.S. dollar, partnerships, S corporations or other entities or arrangements classified as partnerships or disregarded entities for U.S. federal income tax purposes (or persons holding our Common Stock through such entities), stockholders who hold the pre-Reverse Stock Split shares as part of a straddle, hedge, conversion transaction or other integrated or risk reduction transaction, stockholders who hold the pre-Reverse Stock Split shares as qualified small business stock within the meaning of Section 1202 of the Code or Section 1244 stock for purposes of Section 1244 of the Code, stockholders who acquired their Common Stock in a transaction subject to the gain rollover provisions of Section 1045 of the Code, or stockholders who acquired their pre-Reverse Stock Split shares pursuant to the exercise of employee stock options or otherwise as compensation.

In addition, this summary does not address: (a) the tax consequences of transactions effectuated before, after or at the same time as the Reverse Stock Split, whether or not they are in connection with the Reverse Stock Split; (b) any U.S. federal non-income tax consequences of the Reverse Stock Split, including estate, gift or other tax consequences; (c) any state, local or non-U.S. tax consequences of the Reverse Stock Split; (d) the application of the alternative minimum tax, the Medicare contribution tax on net investment income, or the special tax accounting rules under Section 451(b) of the Code, or (e) tax consequences to holders of options, warrants or similar rights to acquire our Common Stock. Stockholders are urged to consult their own tax advisors to determine the particular consequences to them.

Table of Contents

For purposes of this discussion, a “U.S. Holder” means a beneficial owner of shares of our Common Stock that is any of the following:

• an individual who is a citizen or resident of the United States or someone treated as a U.S. citizen or resident for U.S. federal income tax purposes;

• a corporation (or other entity taxable as a corporation for U.S. federal income tax purposes) created or organized in or under the laws of the United States, any state thereof, or the District of Columbia;

• an estate, the income of which is subject to U.S. federal income taxation regardless of its source; or

• a trust if (i) a U.S. court can exercise primary supervision over the trust’s administration and one or more “United States persons” (within the meaning of Section 7701(a)(30) of the Code) are authorized or have the authority to control all substantial decisions of the trust or (ii) it has a valid election in effect under applicable U.S. Treasury Regulations to be treated as a United States person for U.S. federal income tax purposes.

Tax Consequences of the Reverse Stock Split

The Reverse Stock Split should constitute a “recapitalization” for U.S. federal income tax purposes. In general, the U.S. federal income tax consequences of a Reverse Stock Split will vary depending upon whether a U.S. Holder receives cash for fractional shares or solely a reduced number of shares of Common Stock in exchange for its pre-Reverse Stock Split shares of Common Stock. A U.S. Holder that receives solely a reduced number of shares of Common Stock generally will not recognize gain or loss in the Reverse Stock Split. A U.S. Holder’s aggregate tax basis in the reduced number of shares of Common Stock should equal the U.S. Holder’s aggregate tax basis in its pre-Reverse Stock Split shares of Common Stock and such U.S. Holder’s holding period in the reduced number of shares will include the holding period in its pre-Reverse Stock Split shares of Common Stock exchanged. Treasury Regulations provide detailed rules for allocating the tax basis and holding period of the shares of Common Stock surrendered to the shares of Common Stock received in a recapitalization pursuant to the Reverse Stock Split. U.S. Holders should consult their tax advisors as to application of the foregoing rules where shares of Common Stock were acquired at different times or at different prices.

No gain or loss will be recognized by Heliogen as a result of the proposed Reverse Stock Split.

Cash in Lieu of Fractional Shares

A U.S. Holder that receives cash in lieu of a fractional share as a result of the Reverse Stock Split will be treated as having received the fractional shares pursuant to the Reverse Stock Split and then as having exchanged the fractional shares for cash in a redemption by Heliogen, and generally should recognize gain or loss equal to the difference, if any, between the amount of cash received in lieu of fractional shares and the stockholder’s adjusted basis allocable to the fractional share interests. Such gain or loss will be a long-term capital gain or loss if the pre-Reverse Stock Split shares were held for more than one year. Long-term capital gains of individuals are generally subject to tax at reduced rates. There are limitations on the deductibility of capital losses under the Code. A U.S. Holder’s aggregate tax basis in the reduced number of shares of Common Stock should equal the U.S. Holder’s aggregate tax basis in its pre-Reverse Stock Split shares of Common Stock decreased by the basis allocated to the fractional share for which such U.S. Holder is entitled to receive cash, and the holding period of the reduced number of shares of Common Stock received should include the holding period of the pre-Reverse Stock Split shares of Common Stock exchanged.

Information Reporting and Backup Withholding

A holder of shares of Common Stock may be subject to information reporting and backup withholding on cash paid in lieu of fractional shares in connection with the Reverse Stock Split. To avoid backup withholding, each holder of shares of Common Stock that does not otherwise establish an exemption should provide its taxpayer identification number and comply with the applicable certification procedures. Backup withholding is not an additional tax. Any amounts withheld under the backup withholding rules generally will be allowed as a refund or credit against a U.S. Holder’s U.S. federal income tax liability, provided the required information is timely and properly furnished to

the Internal Revenue Service. Holders of shares of Common Stock should consult their tax advisors regarding their qualification for an exemption from backup withholding and the procedures for obtaining such an exemption, as well as the procedures for obtaining a credit or refund if backup withholding is imposed.

The preceding discussion is intended only as a summary of certain material U.S. federal income tax consequences of the Reverse Stock Split. It is not a complete analysis or discussion of all potential tax effects that may be important to a particular holder. All holders of our Common Stock should consult their own tax advisors as to the specific tax consequences of the Reverse Stock Split them, including record retention and tax-reporting requirements, and the applicability and effect of any U.S. federal, state, local and non-U.S. tax laws.

Vote Required

The affirmative vote of the holders of a majority of the outstanding shares entitled to vote on the matter will be required to approve the amendment of our Certificate of Incorporation to effect a Reverse Stock Split of our Common Stock at a ratio in the range of one-for-ten to one-for-forty, such ratio to be determined in the discretion of our Board.

OUR BOARD RECOMMENDS A VOTE “FOR” THE APPROVAL OF THIS REVERSE STOCK SPLIT PROPOSAL.

PROPOSAL NO. 3
RATIFICATION OF appointment OF
INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

Our Audit Committee has selected, and our Board ratified the appointment of PwC as our independent registered public accounting firm for the fiscal year ending December 31, 2023 and has further directed that management submit the selection of its independent registered public accounting firm for ratification by the stockholders at the Annual Meeting. Representatives of PwC are expected to be present at the Annual Meeting. They will have an opportunity to make a statement if they so desire and will be available to respond to appropriate questions.

Neither our Bylaws nor other governing documents or law require stockholder ratification of the selection of PwC as our independent registered public accounting firm. However, our Audit Committee of the Board is submitting the selection of PwC to the stockholders for ratification as a matter of good corporate practice. If the stockholders fail to ratify the selection, our Audit Committee of the Board will reconsider whether or not to retain that firm. Even if the selection is ratified, our Audit Committee of the Board in its discretion may direct the appointment of different independent auditors at any time during the year if they determine that such a change would be in the best interests for us and our stockholders.

Change in Independent Registered Accounting Firm

Dismissal of BDO USA LLP

As reported on the Company’s Current Report on Form 8-K filed on June 6, 2022, effective June 2, 2022, we dismissed BDO USA LLP (“BDO”) as the Company’s independent registered public accounting firm and engaged PwC to serve in this role for the fiscal year ending December 31, 2022.

BDO served as our independent registered public accounting firm from November 5, 2020 through December 30, 2021 (with respect to Legacy Heliogen) and from December 31, 2021 until it was dismissed effective June 2, 2022 (with respect to the Company). BDO audited the Company’s financial statements for the fiscal year ended December 31, 2021 and Legacy Heliogen’s financial statements for the fiscal year ended December 31, 2020. BDO’s report of independent registered public accounting firm, dated March 31, 2022 (except for the effects of the restatement discussed in Note 3, Government Grant paragraph in Note 2, grant revenue presented in Note 4, Income Taxes in Note 9 and Net Loss per Share in Note 11, which is dated May 23, 2022, in the Company’s Annual Report on Form 10-K/A for the year ended December 31, 2021, filed with the Securities and Exchange Commission on May 23, 2022 (the “2021 Form 10-K/A”)), on the Company’s consolidated balance sheets as of December 31, 2021 and 2020, the related consolidated statements of operations, convertible preferred stock and shareholders’ equity (deficit), and cash flows for each of the years then ended, and the related notes to the financial statements (collectively referred to as the “Consolidated Financial Statements”) did not contain any adverse opinion or disclaimer of opinion, and was not qualified or modified as to uncertainties, audit scope or accounting principles.

During the fiscal years ended December 31, 2021 and 2020 and the subsequent interim period through June 2, 2022, there were no “disagreements” (as such term is defined in Item 304(a)(1)(iv) of Regulation S-K and the related instructions to Item 304) with BDO on any matter of accounting principles or practices, financial statement disclosure, or auditing scope or procedure, which disagreements if not resolved to the satisfaction of BDO would have caused BDO to make reference thereto in its reports on the Company’s or Heliogen Holdings Inc.’s (prior to the closing of the business combination, Heliogen, Inc. (“Legacy Heliogen”)) financial statements for such periods and no there were no “reportable events” (as such term is defined in Item 304(a)(1)(v) of Regulation S-K), except for (i) the material weaknesses in the Company’s and Legacy Heliogen’s internal controls over financial reporting as disclosed in the 2021 Form 10-K/A related to the Company and Legacy Heliogen not designing or maintaining an effective control environment specific to the areas of financial reporting and its close process, including effective review of technical accounting matters (e.g., revenue recognition), and proper segregation of duties, including separate review and approval of journal entries and access within our accounting system, and (ii) as disclosed in the Company’s Current Report on Form 8-K, dated May 17, 2022, the determination by the Audit Committee, based on the recommendation of, and after consultation with, the Company’s management, and as discussed with BDO, to restate the Company’s previously issued audited financial statements as of and for the year ended December 31, 2021, as previously filed with the Company’s 2021 Form 10-K/A.

Table of Contents

On June 2, 2022, the Audit Committee made the decision to engage PwC as the Company’s independent registered public accounting firm for the fiscal year ending December 31, 2022, subject to completion of PwC’s standard client acceptance procedures. During the period from December 8, 2020 (Athena’s inception) through December 31, 2021 and the subsequent interim period through and including June 2, 2022, neither the Company nor anyone acting on its behalf consulted PwC regarding either (i) the application of accounting principles to a specified transaction, either completed or proposed, or the type of audit opinion that might be rendered on the Company’s consolidated financial statements and neither a written report nor oral advice was provided to the Company by PwC that PwC concluded was an important factor considered by the Company in reaching a decision as to such accounting, auditing, or financial reporting issue; or (ii) any matter that was either the subject of a “disagreement” (as that term is defined in Item 304(a)(1)(iv) of Regulation S-K and the related instructions) or a “reportable event” (as that term is defined in Item 304(a)(1)(v) of Regulation S-K).

The Company previously provided BDO with a copy of the foregoing disclosures regarding the dismissal reproduced in this Proxy Statement and received a letter from BDO addressed to the SEC stating that they agree with the above statements. This letter was filed as Exhibit 16.1 to the Company’s Current Report on Form 8-K filed on June 6, 2022.

Dismissal of Marcum LLP in connection with the Business Combination

As previously disclosed on the Company’s Current Report on Form 8-K filed on January 6, 2022, on December 30, 2021, we dismissed Marcum LLP (“Marcum”) as our independent registered public accounting firm and appointed BDO as our independent registered public accounting firm. Our Audit Committee approved the decision to change our independent registered public accounting firm. The dismissal of Marcum and the appointment of BDO was done in connection with the completion of the transactions contemplated by the Business Combination Agreement, dated as of July 6, 2021, by and among Athena, HelioMax Merger Sub, Inc. and Legacy Heliogen, including the merger of HelioMax Merger Sub, Inc. with and into Legacy Heliogen, with Legacy Heliogen continuing as the surviving company and a wholly owned subsidiary of the Company (collectively, the “Business Combination”).

Marcum’s report of independent registered public accounting firm dated January 19, 2021 on the balance sheet of Athena as of December 31, 2020, the related statements of operations, changes in stockholders’ equity and cash flows for the period from December 8, 2020 (Athena’s inception) through December 31, 2020 and the related notes to the financial statements did not contain any adverse opinion or disclaimer of opinion, and were not qualified or modified as to uncertainties, audit scope or accounting principles, except for an explanatory paragraph in such report regarding substantial doubt about Athena’s ability to continue as a going concern.

During the period from December 8, 2020 (Athena’s inception) through September 30, 2021 and the subsequent interim period through and including December 30, 2021, there were no “disagreements” (as such term is defined in Item 304(a)(1)(iv) of Regulation S-K and the related instructions to Item 304) with Marcum on any matter of accounting principles or practices, financial statement disclosure, or auditing scope or procedures, which disagreements, if not resolved to the satisfaction of Marcum, would have caused Marcum to make reference thereto in its reports on Athena’s financial statements for such periods. During the period from December 8, 2020 (Athena’s inception) through September 30, 2021 and the subsequent interim period through and including December 30, 2021, there have been no “reportable events” (as such term is defined in Item 304(a)(1)(v) of Regulation S-K), other than: (i) the material weakness in internal controls identified by Athena’s management related to the accounting classification for warrants issued in connection with Athena’s initial public offering, which resulted in the revision of Athena’s IPO Financial Statements (as defined herein) as set forth in Note 2 to Athena’s Quarterly Report on Form 10-Q for the quarterly period ended March 31, 2021, filed with the SEC on May 24, 2021 (the “Q1 Form 10-Q”) and described in Item 4.

As used herein, “Previously Issued Financial Statements” consists of: (a) the audited

Pre-Approval Policies and Procedures

Our Audit Committee has adopted a policy and procedures for the pre-approval of audit and non-audit services rendered by our independent registered public accounting firm. The policy generally pre-approves specified services in the defined categories of audit services, audit-related services and tax services up to specified amounts. Pre-approval may also be given as part of the Audit Committee’s approval of the scope of the engagement of the independent auditor or on an individual, explicit, case-by-case basis before the independent auditor is engaged to provide each service. The pre-approval of services may be delegated to one or more of the Audit Committee’s members, but the decision must be reported to the full Audit Committee at its next scheduled meeting.

Our Audit Committee has determined that the rendering of services other than audit services by our independent registered public accounting firm is compatible with maintaining the principal accountant’s independence.

Vote Required

The affirmative vote of the holders of a majority of the voting power of the shares present in person, by remote communication, or represented by proxy and entitled to vote on the matter will be required to ratify the appointment of PwC as our independent registered public accounting firm for the year ending December 31, 2023.
