Risk factors and legal proceedings

The risks Athena Technology Acquisition Corp. II names in Item 1A of its 10-K filed Mar 11, 2026: 77 risks under these headings, as written.5

  • Risks Relating to our Search for, Consummation of, or Inability to Consummate a Business Combination and Post-Business Combination Risks
  • Our public stockholders may not be afforded an opportunity to vote on our proposed initial business combination, and even if we hold a vote, holders of our founder shares and private placement shares will participate in such vote, which means we may complete our initial business combination even though a majority of our public stockholders do not support such a combination.
  • If we seek stockholder approval of our initial business combination, our initial stockholders and management team have agreed to vote in favor of such initial business combination, regardless of how our public stockholders vote.
  • Your only opportunity to affect the investment decision regarding a potential business combination may be limited to the exercise of your right to redeem your shares from us for cash.
  • The ability of our public stockholders to redeem their shares for cash may make our financial condition unattractive to potential business combination targets, which may make it difficult for us to enter into a business combination with a target.
  • The ability of our public stockholders to exercise redemption rights with respect to a large number of our shares may not allow us to complete the most desirable business combination or optimize our capital structure.
  • The ability of our public stockholders to exercise redemption rights with respect to a large number of our shares could increase the probability that our initial business combination would be unsuccessful and that you would have to wait for liquidation in order to redeem your shares.
  • The requirement that we complete our initial business combination by June 14, 2026 may give potential target businesses leverage over us in negotiating a business combination and may limit the time we have in which to conduct due diligence on potential business combination targets, in particular as we approach our dissolution deadline, which could undermine our ability to complete our initial business combination on terms that would produce value for our stockholders.
  • We may not be able to complete our initial business combination by June 14, 2026, in which case we would cease all operations except for the purpose of winding up and we would redeem our public shares and liquidate, in which case our public stockholders may only receive $14.41 per share based on the amount held in the Trust Account as of December 31, 2025, or less than such amount in certain circumstances, and our warrants will expire worthless.
  • Challenging market conditions have caused an increasing number of special purpose acquisition companies to be unable to complete an initial business combination.
  • If we seek stockholder approval of our initial business combination, our Sponsor, initial stockholders, directors, executive officers and their affiliates may elect to purchase shares or public warrants from public stockholders, which may influence a vote on a proposed business combination and reduce the public “float” of our Class A common stock.
  • If a stockholder fails to receive notice of our offer to redeem our public shares in connection with our initial business combination, or fails to comply with the procedures for tendering its shares, such shares may not be redeemed.
The other 65 risks
  • You will not have any rights or interests in funds from the Trust Account, except under certain limited circumstances. Therefore, to liquidate your investment, you may be forced to sell your public shares or warrants, potentially at a loss.
  • You will not be entitled to protections normally afforded to investors of many other blank check companies.
  • As the number of special purpose acquisition companies (“SPACs”) evaluating targets increases, attractive targets may become scarcer and there may be more competition for attractive targets. This could increase the cost of our initial business combination and could even result in our inability to consummate an initial business combination.
  • Changes in the market for directors and officers liability insurance could make it more difficult and more expensive for us to negotiate and complete an initial business combination.
  • Because of our limited resources and the significant competition for business combination opportunities, it may be more difficult for us to complete our initial business combination. If we are unable to complete our initial business combination, our public stockholders may receive only their pro rata portion of the funds in the Trust Account that are available for distribution to public stockholders, and our warrants will expire worthless.
  • If our available working capital funds are insufficient to allow us to operate for at least until June 14, 2026, it could limit the amount available to fund our search for a target business or businesses and complete our initial business combination, and we will depend on loans from our Sponsor or management team to fund our search and to complete our initial business combination.
  • Subsequent to our completion of our initial business combination, we may be required to take write-downs or write-offs, restructuring and impairment or other charges that could have a significant negative effect on our financial condition, results of operations and the price of our securities, which could cause you to lose some or all of your investment.
  • If third parties bring claims against us, the proceeds held in the Trust Account could be reduced and the per-share redemption amount received by stockholders may be less than the $14.41 per share held in the Trust Account as of December 31, 2025.
  • Our directors may decide not to enforce the indemnification obligations of our Sponsor, resulting in a reduction in the amount of funds in the Trust Account available for distribution to our public stockholders.
  • We may not have sufficient funds to satisfy indemnification claims of our directors and executive officers.
  • If, after we distribute the proceeds in the Trust Account to our public stockholders, we file a bankruptcy petition or an involuntary bankruptcy petition is filed against us that is not dismissed, a bankruptcy court may seek to recover such proceeds, and the members of our board of directors may be viewed as having breached their fiduciary duties to our creditors, thereby exposing the members of our board of directors and us to claims of punitive damages.
  • If, before distributing the proceeds in the Trust Account to our public stockholders, we file a bankruptcy petition or an involuntary bankruptcy petition is filed against us that is not dismissed, the claims of creditors in such proceeding may have priority over the claims of our stockholders and the per-share amount that would otherwise be received by our stockholders in connection with our liquidation may be reduced.
  • Our stockholders may be held liable for claims by third parties against us to the extent of distributions received by them upon redemption of their shares.
  • We may seek business combination opportunities in industries or sectors that may be outside of our management’s areas of expertise.
  • We may seek business combination opportunities with an early stage company, a financially unstable business or an entity lacking an established record of revenue, cash flow or earnings, which could subject us to volatile revenues, cash flows or earnings or difficulty in retaining key personnel.
  • We are not required to obtain an opinion from an independent investment banking firm or from a valuation or appraisal firm, and consequently, you may have no assurance from an independent source that the price we are paying for the business is fair to our stockholders from a financial point of view.
  • Because we must furnish our stockholders with target business financial statements, we may lose the ability to complete an otherwise advantageous initial business combination with some prospective target businesses.
  • Compliance obligations under the Sarbanes-Oxley Act may make it more difficult for us to effectuate our initial business combination, require substantial financial and management resources, and increase the time and costs of completing an initial business combination.
  • We have identified a material weakness in our internal control over financial reporting. This material weakness could continue to adversely affect our ability to report our results of operations and financial condition accurately and in a timely manner.
  • The restatement of the Company’s financial statements may lead to additional risks and uncertainties, including regulatory, litigation, stockholder or other actions, loss of investor and counterparty confidence and negative impacts on our stock price.
  • In order to effectuate an initial business combination, special purpose acquisition companies have, in the recent past, amended various provisions of their charters and other governing instruments, including their warrant agreements. We cannot assure you that we will not seek to amend our amended and restated certificate of incorporation or governing instruments in a manner that will make it easier for us to complete our initial business combination that our stockholders may not support.
  • Certain agreements related to the initial public offering may be amended without stockholder approval.
  • We may be unable to obtain additional financing to complete our initial business combination or to fund the operations and growth of a target business, which could compel us to restructure or abandon a particular business combination.
  • Our initial stockholders control a substantial interest in us and thus may exert a substantial influence on actions requiring a stockholder vote, potentially in a manner that you do not support.
  • Our initial business combination and our structure thereafter may not be tax-efficient to our stockholders and warrant holders. As a result of our business combination, our tax obligations may be more complex, burdensome and uncertain.
  • Resources could be wasted in researching business combinations that are not completed, which could materially adversely affect subsequent attempts to locate and acquire or merge with another business. If we are unable to complete our initial business combination, our public stockholders may only receive their pro rata portion of the funds in the Trust Account that are available for distribution to public stockholders, and our warrants will expire worthless.
  • Our key personnel may negotiate employment or consulting agreements with a target business in connection with a particular business combination, and a particular business combination may be conditioned on the retention or resignation of such key personnel. These agreements may provide for them to receive compensation following our initial business combination and as a result, may cause them to have conflicts of interest in determining whether a particular business combination is the most advantageous.
  • We may have a limited ability to assess the management of a prospective target business and, as a result, may effect our initial business combination with a target business whose management may not have the skills, qualifications or abilities to manage a public company.
  • The officers and directors of an acquisition candidate may resign upon completion of our initial business combination. The loss of a business combination target’s key personnel could adversely impact the operations and profitability of our post-combination business.
  • If we effect our initial business combination with a company located outside of the United States, we would be subject to a variety of additional risks that may adversely affect us.
  • If our management following our initial business combination is unfamiliar with U.S. securities laws, they may have to expend time and resources becoming familiar with such laws, which could lead to various regulatory issues.
  • We may issue notes or other debt securities, or otherwise incur substantial debt, to complete a business combination, which may adversely affect our leverage and financial condition and thus adversely impact the value of our stockholders’ investment in us.
  • We may only be able to complete one business combination with the proceeds of the initial public offering and the sale of the private placement units, which will cause us to be solely dependent on a single business which may have a limited number of products or services. This lack of diversification may adversely impact our operations and profitability.
  • We may attempt to simultaneously complete business combinations with multiple prospective targets, which may hinder our ability to complete our initial business combination and give rise to increased costs and risks that could adversely impact our operations and profitability.
  • We may attempt to complete our initial business combination with a private company about which little information is available, which may result in a business combination with a company that is not as profitable as we suspected, if at all.
  • We may issue our shares to investors in connection with our initial business combination at a price that is less than the prevailing market price of our shares at that time.
  • Risks Relating to our Sponsor and Management Team
  • Our ability to successfully effect our initial business combination and to be successful thereafter will be dependent upon the efforts of our key personnel, some of whom may join us following our initial business combination. The loss of key personnel could negatively impact the operations and profitability of our post-combination business.
  • We are dependent upon our executive officers and directors and their departure could adversely affect our ability to operate.
  • The nominal purchase price paid by our Sponsor for the founder shares may significantly dilute the implied value of your public shares in the event we consummate an initial business combination, and our Sponsor is likely to make a substantial profit on its investment in us in the event we consummate an initial business combination, even if the business combination causes the trading price of our shares of common stock to materially decline.
  • Since our Sponsor, executive officers and directors will lose their entire investment in us if our initial business combination is not completed (other than with respect to public shares they may acquire during or after the initial public offering), a conflict of interest may arise in determining whether a particular business combination target is appropriate for our initial business combination.
  • Our executive officers and directors will allocate their time to other businesses thereby causing conflicts of interest in their determination as to how much time to devote to our affairs. This conflict of interest could have a negative impact on our ability to complete our initial business combination.
  • Our officers and directors presently have, and any of them in the future may have additional, fiduciary or contractual obligations to other entities and, accordingly, may have conflicts of interest in determining to which entity a particular business opportunity should be presented.
  • Our executive officers, directors, security holders and their respective affiliates may have competitive pecuniary interests that conflict with our interests.
  • We may engage in a business combination with one or more target businesses that have relationships with entities that may be affiliated with our Sponsor, executive officers, directors or existing holders which may raise potential conflicts of interest.
  • Our management may not be able to maintain control of a target business after our initial business combination. We cannot provide assurance that, upon loss of control of a target business, new management will possess the skills, qualifications or abilities necessary to profitably operate such business.
  • Members of our management team and board of directors have significant experience as founders, board members, officers or executives of other companies. As a result, certain of those persons have been, or may become, involved in proceedings, investigations and litigation relating to the business affairs of the companies with which they were, are, or may be in the future be, affiliated. These activities may have an adverse effect on us, which may impeded our ability to consummate an initial business combination.
  • Risks Relating to our Securities
  • Our securities have been delisted from trading on NYSE American, which could limit investors’ ability to make transactions in our securities and subject us to additional trading restrictions.
  • The securities in which we invest the funds held in the Trust Account could bear a negative rate of interest, which could reduce the value of the assets held in trust such that the per-share redemption amount received by public stockholders may be less than the $14.41 per share held in the Trust Account as of December 31, 2025.
  • If we are deemed to be an investment company under the Investment Company Act, we may be required to institute burdensome compliance requirements and our activities may be restricted, which may make it difficult for us to complete our initial business combination.
  • Increases in inflation and interest rates in the United States and elsewhere could make it more difficult for us to consummate an initial business combination.
  • If we seek stockholder approval of our initial business combination and we do not conduct redemptions pursuant to the tender offer rules, and if you or a “group” of stockholders are deemed to hold in excess of 15% of our Class A common stock, you will lose the ability to redeem all such shares in excess of 15% of our Class A common stock.
  • Since our Sponsor paid only approximately $0.003 per share for the founder shares, certain of our officers and directors could potentially make a substantial profit even if we acquire a target business that subsequently declines in value.
  • You will not be permitted to exercise your warrants unless we register and qualify the underlying Class A common stock or certain exemptions are available.
  • You may only be able to exercise your public warrants on a “cashless basis” under certain circumstances, and if you do so, you will receive fewer shares of Class A common stock from such exercise than if you were to exercise such warrants for cash.
  • We may amend the terms of the public warrants in a manner that may be adverse to holders of public warrants with the approval by the holders of at least a majority of the then outstanding public warrants. As a result, the exercise price of your warrants could be increased, the exercise period could be shortened and the number of shares of Class A common stock purchasable upon exercise of a warrant could be decreased, all without your approval.
  • Our public warrant agreement designates the courts of the State of New York or the United States District Court for the Southern District of New York as the sole and exclusive forum for certain types of actions and proceedings that may be initiated by holders of our public warrants, which could limit the ability of warrant holders to obtain a favorable judicial forum for disputes with our company.
  • We may redeem your unexpired warrants prior to their exercise at a time that is disadvantageous to you, thereby making your warrants worthless.
  • Our warrants and founder shares may have an adverse effect on the market price of our shares of Class A common stock and make it more difficult to effectuate our initial business combination.
  • Because each unit contains one-half of one public warrant and only a whole warrant may be exercised, the units may be worth less than units of other special purpose acquisition companies.
  • A provision of our warrant agreement may make it more difficult for us to consummate an initial business combination.
  • The grant of registration rights to our initial stockholders and holders of our private placement units may make it more difficult to complete our initial business combination, and the future exercise of such rights may adversely affect the market price of our shares of Class A common stock.
  • Provisions in our amended and restated certificate of incorporation and Delaware law may inhibit a takeover of us, which could limit the price investors might be willing to pay in the future for our shares of Class A common stock and could entrench management.
  • A 1% U.S. federal excise tax was previously and may in the future be imposed in the future on us in connection with redemptions by us of our shares or our liquidation.
  • Whether a redemption of Class A common stock will be treated as a sale of such Class A common stock for U.S. federal income tax purposes will depend on a stockholder’s specific facts.
  • Provisions in our amended and restated certificate of incorporation and Delaware law may have the effect of discouraging lawsuits against our directors and officers.
  • General Risk Factors
