Athena Technology Acquisition Corp. Reminds Shareholders to Vote in Favor of Business Combination with Heliogen, Inc.

KENNESAW, Ga.–(BUSINESS WIRE)–Athena Technology Acquisition Corp. (NYSE: ATHN) (“ATHN”), a publicly-traded special purpose acquisition company, reminds its shareholders to vote in favor of the previously announced business combination (the “Business Combination”) with Heliogen, Inc. (“Heliogen”), an AI-enabled, modular concentrated solar technology company focused on decarbonizing industry.

Shareholders who owned common stock of ATHN as of the close of business on November 23, 2021 (the “Record Date”), may vote their shares. Shareholders as of the Record Date continue to have the right to vote their shares, regardless of whether such shareholders subsequently sold their shares and do not own such shares as of the date they cast their vote.

The extraordinary general meeting of ATHN shareholders to approve the pending Business Combination (the “Extraordinary General Meeting”) is scheduled to be held on December 28, 2021 at 10:00 a.m. Eastern Time. The Extraordinary General Meeting will be conducted virtually, and can be accessed via live webcast at https://www.cstproxy.com/athenatechnology/2021.

Additional information on how shareholders of record may vote their shares can be found at: https://www.athena1.com/athn-vote.

Every shareholder’s vote is important, regardless of the number of shares held. Accordingly, all ATHN shareholders who held shares as of the Record Date who have not yet voted are encouraged to do so as soon as possible so that their votes are received by ATHN no later than 11:59 p.m. Eastern Time December 27, 2021. For the avoidance of doubt, ATHN shareholders who owned shares as of the Record Date and subsequently sold all or a portion of their shares are STILL entitled to vote, and are encouraged to do so.

ATHN’s board of directors recommends you vote “FOR” the Business Combination with Heliogen and “FOR” all of the related proposals described in the definitive proxy statement/prospectus (the “Proxy Statement”) filed by ATHN with the Securities and Exchange Commission (“SEC”) on December 3, 2021.

These are the two easiest and fastest ways to vote – and they are both free:

• Vote Online (Highly Recommended): Follow the instructions provided on the proxy card that was mailed to you, if you are a holder of record, or provided by your broker, bank or other nominee on the Voting Instruction Form mailed (or e-mailed) to you, if you hold your shares “in street name”. To vote online, you will need your voting control number, which you can find on your proxy card or the Voting Instruction Form provided by your broker, bank or other nominee. Votes submitted electronically over the Internet must be received by 11:59 p.m., Eastern Time, on December 27, 2021. However, if you hold your shares through a broker, bank or other nominee, they may have an earlier deadline to receive your vote.

• Vote at the Meeting: follow the instructions provided by your broker, bank or other nominee on the Voting Instruction Form mailed (or e-mailed) to you. If you plan to attend the online Special Meeting, you will need your 12-digit voting control number to vote electronically at the Special Meeting. You can find your control number and the address for the Special Meeting on your proxy card or the Voting Instruction Form provided by your brokers, bank or nominee.

Additionally, you can also vote by mail:

• Vote by Mail: follow the instructions provided by your broker, bank or other nominee on the proxy card that was mailed to you, if you are a holder of record, or on the Voting Instruction Form mailed or e-mailed to you. You will need your voting control number which is included on the Voting Instruction Form mailed or e-mailed to you in order to vote by mail. Please be sure to, (1) mark, sign and date your Voting Instruction Form, (2) fold and return your Voting Instruction Form in the postage-paid envelope provided with your proxy material, and (3) mail your Voting Instruction Form to ensure receipt on or before 10:00 a.m., Eastern Time, on December 28, 2021

YOUR CONTROL NUMBER IS FOUND ON YOUR VOTING INSTRUCTION FORM. If you did not receive or misplaced your Voting Instruction Form, contact your bank, broker or other nominee to obtain your control number in order to vote. A bank, broker or other nominee is a person or firm that acts as an intermediary between an investor and the stock exchange who can help you vote your shares.

If any individual ATHN shareholder, who held shares as of the November 23, 2021 record date for voting, does not receive the Proxy Statement, such shareholder should (i) confirm their Proxy Statement’s status with their broker, (ii) contact Morrow Sodali LLC, ATHN’s proxy solicitor, for assistance via e-mail at ATHN.info@investor.morrowsodali.com or toll-free call at (800) 662-5200 and banks and brokers can place a collect call to Morrow Sodali at (203) 658-9400, or (iii) contact ATHN by mail at Athena Technology Acquisition Corp., 125 Townpark Drive, Suite 300, Kennesaw, GA 30144.
