Risk factors and legal proceedings

The risks Clearthink 1 Acquisition Corp. names in Item 1A of its 10-K filed Mar 31, 2026: 76 risks under these headings, as written.3

  • Risks Relating to Our Search for, and Consummation of or Inability to Consummate, a Business Combination
  • Our shareholders may not be afforded an opportunity to vote on our proposed initial business combination, and even if we hold a vote, holder(s) of our founder shares will participate in such vote, which means we may complete our initial business combination even though a majority of our public shareholders do not support such a combination.
  • Our sponsor has the ability to remove itself as the Company’s sponsor or to substantially reduce its interests in the Company before identifying a business combination, which may result in change in the strategy and focus of our Company in pursuing a business combination.
  • If we seek shareholder approval of our initial business combination, our initial shareholder and management team have agreed to vote in favor of such initial business combination, regardless of how our public shareholders vote.
  • Your only opportunity to effect your 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 shareholders 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 shareholders 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, and may substantially dilute your investment in us.
  • The ability of our public shareholders 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 within the completion window 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 shareholders.
  • Our search for a business combination, and any target business with which we ultimately consummate a business combination, may be materially adversely affected by events that are outside of our control, such as increased geopolitical unrest, pandemic outbreaks, and volatility in the debt and equity markets.
  • We may not be able to complete our initial business combination within the completion window, in which case we would cease all operations except for the purpose of winding up and we would redeem our public shares and, subject to the approval of our remaining shareholders and our directors, liquidate and dissolve, subject in each case to our obligations under Cayman Islands law to provide for claim of creditors and the requirements of other applicable law.
  • We may decide not to seek to extend the term we have to consummate our initial business combination, in which case we would redeem our public shares, and the rights may be worthless.
The other 64 risks
  • If we seek shareholder approval of our initial business combination, our sponsor, initial shareholder, directors, executive officers, advisors and their affiliates may elect to purchase shares or public rights from public shareholders, which may influence a vote on a proposed business combination and reduce the public “float” of our securities.
  • If a shareholder fails to receive notice of our offer to redeem our public shares in connection with the closing of our initial business combination, or fails to comply with the procedures for tendering its shares, such shares may not be redeemed.
  • You will not be entitled to protections normally afforded to investors of other blank check companies subject to Rule 419 of the Securities Act.
  • If we seek shareholder 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 shareholders are deemed to hold in excess of 15% of our Class A ordinary shares, you may lose the ability to redeem all such shares in excess of 15% of our Class A ordinary shares.
  • 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 shareholders may receive only their pro rata portion of the funds in the trust account that are available for distribution to public shareholders, and our rights will expire worthless.
  • As the number of special purpose acquisition companies 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 find a target or to consummate an initial business combination.
  • If the net proceeds of our initial public offering not being held in the trust account are insufficient to allow us to operate for at least the duration of the completion window, it could limit the amount of cash 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.
  • 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 shareholders may be less than $10.00 per share.
  • 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 shareholders.
  • If, after we distribute the proceeds in the trust account to our public shareholders, we file a bankruptcy or winding-up petition or an involuntary bankruptcy or winding up petition is filed against us that is not dismissed, a bankruptcy or insolvency 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 shareholders, we file a bankruptcy or winding-up petition or an involuntary bankruptcy or winding up petition is filed against us that is not dismissed, the claims of creditors in such proceeding may have priority over the claims of our shareholders and the per-share amount that would otherwise be received by our shareholders in connection with our liquidation may be reduced.
  • 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 or force us to abandon our efforts to complete an initial business combination.
  • Our shareholders 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 not hold an annual general meeting until after the consummation of our initial business combination, which could delay the opportunity for our shareholders to appoint directors.
  • Because we are neither limited to evaluating a target business in a particular industry sector nor have we selected any specific target businesses with which to pursue our initial business combination, you will be unable to ascertain the merits or risks of any particular target business’s operations.
  • Although we have identified general criteria and guidelines that we believe are important in evaluating prospective target businesses, we may enter into our initial business combination with a target that does not meet such criteria and guidelines, and as a result, the target business with which we enter into our initial business combination may not have attributes entirely consistent with our general criteria and guidelines.
  • We may not be 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 consideration we are paying for the business is fair to our company from a financial point of view.
  • 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 negatively impact the value of our shareholders’ investment in us.
  • We may only be able to complete one business combination with the proceeds of our initial public offering and the sale of the private 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 negatively 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 negatively 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 do not have a specified maximum redemption threshold. The absence of such a redemption threshold may make it possible for us to complete our initial business combination with which a substantial majority of our shareholders do not agree.
  • 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. We cannot assure you that we will not seek to amend our amended and restated memorandum and articles of association or governing instruments in a manner that will make it easier for us to complete our initial business combination that our shareholders may not support.
  • Certain agreements related to our initial public offering may be amended without shareholder 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 shareholder controls a substantial interest in us and thus may exert a substantial influence on actions requiring a shareholder vote, potentially in a manner that you do not support.
  • We may not be able to complete an initial business combination since such initial business combination may be subject to regulatory review and approval requirement, including foreign investment regulations and review by government entities such as the Committee on Foreign Investment in the United States (“CFIUS”), or may be ultimately prohibited.
  • Because we must furnish our shareholders 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 may seek business combination opportunities with a high degree of complexity that require significant operational improvements, which could delay or prevent us from achieving our desired results.
  • Our initial business combination and our structure thereafter may not be tax-efficient to our shareholders and right holders. As a result of our business combination, our tax obligations may be more complex, burdensome and uncertain.
  • Risks Relating to the Post-Business Combination Company
  • 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.
  • The nominal purchase price paid by our sponsor for the founder shares may result in significant dilution to the implied value of your public shares upon the consummation of our 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 Class A ordinary shares to materially decline.
  • The value of the founder shares following completion of our initial business combination is likely to be substantially higher than the nominal price paid for them, even if the trading price of our ordinary shares at such time is substantially less than $10.00 per share.
  • 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 shareholders may only receive their pro rata portion of the funds in the trust account that are available for distribution to public shareholders, and our rights will expire worthless.
  • 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.
  • 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 negatively impact the operations and profitability of our post-combination business.
  • 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.
  • Risks Relating to Acquiring and Operating a Business in Foreign Countries
  • 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.
  • After our initial business combination, substantially all of our assets may be located in a foreign country and substantially all of our revenue will be derived from our operations in such country. Accordingly, our results of operations and prospects will be subject, to a significant extent, to the economic, political and legal policies, developments and conditions in the country in which we operate.
  • Exchange rate fluctuations and currency policies may cause a target business’ ability to succeed in the international markets to be diminished.
  • We may reincorporate in or transfer by way of continuation to another jurisdiction in connection with the closing of our initial business combination and such reincorporation or transfer by way of continuation may result in taxes imposed on shareholders.
  • We may reincorporate in or transfer by way of continuation to another jurisdiction in connection with the closing of our initial business combination, and the laws of such jurisdiction may govern some or all of our future material agreements and we may not be able to enforce our legal rights.
  • We are subject to changing law and regulations regarding regulatory matters, corporate governance and public disclosure that have increased both our costs and the risk of non-compliance.
  • Risks Relating to our Management Team
  • We may not have sufficient funds to satisfy indemnification claims of our directors and executive officers.
  • Members of our management team and board of directors have significant experience as board members, officers or executives of other companies. As a result, certain of those persons have been, are, and may become, involved in proceedings, investigations and litigation relating to the business affairs of the companies with which they were, are, or may in the future be, affiliated. This may have an adverse effect on us, which may impede our ability to consummate an initial business combination.
  • Members of our management team and affiliated companies may have been, and may in the future be, involved in civil disputes or governmental investigations unrelated to our business.
  • Past performance by our management team and their affiliates may not be indicative of future performance of an investment in us.
  • We may seek business combination opportunities in industries or sectors that may be outside of our management’s areas of expertise.
  • We are dependent upon our executive officers and directors and their loss, or a reduction in the amount of time they can dedicate to our initial business combination, could adversely affect our ability to operate.
  • 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, including blank check companies, and, accordingly, may have conflicts of interest in allocating their time and 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.
  • Risks Relating to our Securities
  • 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 rights, potentially at a loss.
  • 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 shareholders may be less than $10.00 per share.
  • Nasdaq may delist our securities from trading on its exchange, which could limit investors’ ability to make transactions in our securities and subject us to additional trading restrictions.
  • The grant of registration rights to our initial shareholder and holder(s) of our private 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 Class A ordinary shares.
  • We may issue additional Class A ordinary shares or preferred shares to complete our initial business combination or under an employee incentive plan after completion of our initial business combination. Any such issuances would dilute the interest of our shareholders and likely present other risks.
  • Our initial shareholder paid an aggregate of $25,000 or approximately $0.005 per founder share and, accordingly, you will experience immediate and substantial dilution from the purchase of our Class A ordinary shares.
  • We may amend the terms of the rights in a manner that may be adverse to holders of public rights with the approval by the holders of at least 50% of the then outstanding public rights.
  • Our rights may have an adverse effect on the market price of our Class A ordinary shares and make it more difficult to effectuate our initial business combination.

Legal proceedings

There is no material litigation, arbitration or governmental proceeding currently pending against us or any members of our management team and our board of directors in their capacity as such.
