Properties, in its own words

We currently maintain our corporate offices at 1731 Embarcadero Rd., Suite 200, Palo Alto, CA 94303. The cost for this space is included in the $30,000 per month fee that we pay an affiliate of our Sponsor for office space, administrative and support services. We believe, based on fees for similar services in the San Francisco Bay Area, that the fee charged by our Sponsor is at least as favorable as we could have obtained from an unaffiliated party. We consider our current office space, combined with the other office space otherwise available to our executive officers, adequate for our current operations.

Risk factors and legal proceedings

The risks GigCapital8 Corp. names in Item 1A of its 10-K filed Mar 31, 2026: 77 risks under these headings, as written.3

  • Risks Relating to our Search for, and Consummation of or Inability to Consummate, a Business Combination
  • Our public shareholders may not be afforded an opportunity to vote on our proposed business combination, and even if we hold a vote, holders of our founder shares, private investor shares and private placement shares will
  • participate in such vote, which means we may consummate our initial business combination even though a majority of our public shareholders do not support such a combination.
  • 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 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 our initial business combination with a target.
  • The requirement that we maintain a minimum net worth or retain a certain amount of cash could increase the probability that our 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 24 months from the closing of the Offering may give potential target businesses leverage over us in negotiating our initial business combination and may limit the amount of time we have to conduct due diligence on potential business combination targets as we approach our dissolution deadline, which could undermine our ability to consummate our initial business combination on terms that would produce value for our shareholders.
  • We may not be able to consummate our initial business combination within the required time period, in which case we would cease all operations except for the purpose of winding up and we would redeem our public shares and liquidate.
  • Our search for an initial business combination, and any target business with which we may ultimately consummate an initial business combination, may be materially adversely affected by current global geopolitical conditions resulting from the ongoing Russia-Ukraine conflict, the Israel-Hamas conflict, the escalating military conflict involving the United States, Israel and Iran, the resumption of Houthi attacks on Red Sea shipping, and other hostilities in the Middle East, Southwest Asia and globally.
  • Our search for and ability to complete a business combination, and any target business with which we ultimately complete a business combination, may be adversely affected by general market conditions, political considerations, pandemics, volatility in the capital and debt markets and other social and geopolitical events.
  • Macro-economic turbulence and instability relating to recent and ongoing global conflicts and other drivers of uncertainty may adversely affect our business, investments and results of operations and our ability to successfully consummate a business combination.
  • Fluctuations in the rate of inflation in the United States and elsewhere could make it more difficult for us to complete our initial business combination.
The other 65 risks
  • As the number of SPACs evaluating targets increases, and other issued SPAC entities may come to market with superior terms for the acquisition targets, 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 we seek shareholder approval of our initial business combination pursuant to a proxy solicitation, our Sponsor, directors, executive officers, and their affiliates may elect to purchase shares from other shareholders, in which case they may influence a vote in favor of a proposed business combination that you do not support.
  • If a shareholder 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.
  • 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 approximately $10.00 per share, or less in certain circumstances, on our redemption of their shares.
  • We will require public shareholders who wish to redeem their public shares in connection with a proposed business combination to comply with specific requirements for redemption that may make it more difficult for them to exercise their redemption rights prior to the deadline for exercising their rights.
  • If we seek shareholder approval of our business combination pursuant to a proxy solicitation (meaning we would 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 the issued and outstanding public shares sold in the Offering, you will lose the ability to redeem all such shares in excess of 15% of the issued and outstanding public shares sold in the Offering.
  • If the net proceeds of the Offering and the sale of the private investor shares and private placement units not being held in the trust account are insufficient to allow us to operate for at least the next 24 months from the closing of the Offering, we may be unable to 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.
  • We may issue notes or other debt securities, or otherwise incur substantial debt, to complete our initial business combination, which may adversely affect our financial condition and thus negatively impact the value of our shareholders’ investment in us.
  • Our directors may decide not to enforce indemnification obligations against our Sponsor, resulting in a reduction in the amount of funds in the trust account available for distribution to our public shareholders.
  • 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.
  • Our shareholders may be held liable for claims by third parties against us to the extent of distributions received by them.
  • If third parties bring claims against the Company, the proceeds held in trust could be reduced and the per-share redemption price received by shareholders may be less than $10.00 per share.
  • Unlike some other similarly structured blank check companies, our Sponsor will receive additional Class A ordinary shares if we issue shares to consummate an initial business combination.
  • The grant of registration rights to our initial shareholders, including the non-managing investors, 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 public shares.
  • Because we are not limited to any particular business or specific geographic location or 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’ operations.
  • The requirement that the acquisition target(s) that we acquire must collectively have a fair market value equal to at least 80% of the balance of the funds in the trust account (less any taxes payable on interest earned) at the time of the execution of a definitive agreement for our initial business combination may limit the type and number of companies with which we may complete such a business combination.
  • We may seek acquisition opportunities outside the A&D, cybersecurity and secured communications and quantum-based command and control systems, AI and ML industries, which may be outside of our management’s areas of expertise.
  • Although we 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 seek acquisition opportunities with an early-stage company, a financially unstable business or an entity lacking an established record of revenue or earnings.
  • We are not required to obtain an opinion from an independent investment banking firm or another independent entity, and consequently, an independent source may not confirm that the price we are paying for the business is fair to our shareholders from a financial point of view.
  • We may issue additional ordinary or preferred shares to complete our initial business combination or under an employee incentive plan upon or after consummation of our initial business combination, which would dilute the interest of our shareholders and likely present other risks.
  • Resources could be wasted in researching acquisitions that are not consummated, which could materially adversely affect subsequent attempts to locate and acquire or merge with another business. If we do not complete our initial
  • business combination within the required time period, our public shareholders may receive only approximately $10.00 per public share, or less in certain circumstances, on the liquidation of our trust account.
  • We may engage in our initial business combination with one or more target businesses that have relationships with entities that may be affiliated with our Sponsor, executive officers or directors, which may raise potential conflicts of interest.
  • Since our Sponsor, officers and directors, any other holder of our founder shares, private investor shares and private placement units, including the non-managing investors, will lose their entire investment in us if our initial business combination is not consummated (other than with respect to public shares they may acquire during or after the Offering), and our executive officers and directors have significant financial interests in our Sponsor, a conflict of interest may arise in determining whether a particular acquisition target is appropriate for our initial business combination.
  • We may only be able to complete one business combination with the proceeds of the Offering, and the sale of the private investor shares and 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 negatively impact our operations and profitability.
  • We may attempt to simultaneously consummate business combinations with multiple prospective targets, which may hinder our ability to consummate our initial business combination and give rise to increased costs and risks that could negatively impact our operations and profitability.
  • We may attempt to consummate our initial business combination with a private company about which little information is available, which may result in our initial business combination with a company that is not as profitable as we suspected, or at all.
  • Unlike some blank check companies, we do not have a specified maximum redemption threshold. The absence of such a redemption threshold may make it easier for us to consummate our initial business combination with which a substantial majority of our shareholders do not agree.
  • 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. If we are unable to complete our initial business combination, our public shareholders may only receive $10.00 per share or potentially less than $10.00 per share on our redemption.
  • Our initial shareholders will control a substantial interest in us and thus may influence certain actions requiring a shareholder vote.
  • 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.
  • Redeeming shareholders may be unable to sell their securities when they wish to in the event that the proposed business combination is not approved.
  • Our management team, the non-managing investors and our Sponsor may make a profit on any initial business combination, even if any public shareholders who did not redeem their shares would experience a loss on that business combination. As a result, the economic interests of our management team, the non-managing investors and our Sponsor may not fully align with the economic interests of public shareholders.
  • If we are unable to consummate our initial business combination within 24 months from the closing of the Offering, our public shareholders may be forced to wait beyond such period before redemption from our trust account.
  • We may be unable to consummate an initial business combination if a target business requires that we have a certain amount of cash at closing, in which case public shareholders may have to remain shareholders of our Company and wait until our redemption of the public shares to receive a pro rata share of the trust account or attempt to sell their shares on the open market.
  • Our Sponsor may decide not to extend the term we have to consummate our initial business combination, in which case we would cease all operations except for the purpose of winding up and we would redeem our public shares and liquidate.
  • 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.
  • We may not hold an annual meeting of shareholders until after the consummation of our initial business combination.
  • In order to effectuate an initial business combination, blank check companies have, in the recent past, amended various provisions of their charters and other governing instruments. We may 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.
  • If, after we distribute the proceeds in the trust account to our public shareholders, 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 shareholders, 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 shareholders and the per-share amount that would otherwise be received by our shareholders in connection with our liquidation may be reduced.
  • Holders of Class A ordinary shares will not be entitled to vote on any appointment of directors we hold prior to the completion of our initial business combination and will also not be able to vote on our continuation in a jurisdiction outside the Cayman Islands prior to our initial business combination.
  • We may not be able to complete a business combination with certain potential target companies if a proposed transaction with the target company may be subject to review or approval by regulatory authorities pursuant to certain U.S. or foreign laws or regulations.
  • We may engage one or more of our underwriters or one of their respective affiliates to provide additional services to us after the Offering, which may include acting as M&A advisor in connection with an initial business combination or as placement agent in connection with a related financing transaction for an additional fee. These financial incentives may cause them to have potential conflicts of interest in rendering any such additional services to us after the Offering, including, for example, in connection with the sourcing and consummation of an initial business combination.
  • Changes in international trade policies, tariffs and treaties affecting imports and exports may have a material adverse effect on our search for an initial business combination target or the performance or business prospects of a post-business combination company.
  • Risks Relating to the Post-Business Combination Company
  • Subsequent to our consummation of our initial business combination, we may be required to take write-downs or write-offs, or we may be subject to 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 public shares, which could cause you to lose some or all of your investment.
  • Our management team and our shareholders may not be able to maintain control of a target business after our initial business combination.
  • Transactions in connection with or in anticipation of our initial business combination and our structure thereafter may not be tax-efficient to our shareholders. As a result of our initial business combination, our tax obligations may be more complex, burdensome and uncertain.
  • 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.
  • The post-business combination company may issue shares to investors in connection with our initial business combination at a price which is less than $10.00 or the prevailing market price of our shares at that time, which could dilute the interests of our existing shareholders and add costs.
  • 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.
  • Risks Relating to Our Management Team
  • Our 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 ability to successfully effect our initial business combination and to be successful thereafter will be largely dependent upon the efforts of our executive officers and directors, some of whom may join the post-transaction
  • company following our initial business combination. The loss of our executive officers or directors could negatively impact the operations and profitability of our business.
  • 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.
  • Certain of our officers and directors are now, and all of them may in the future become, affiliated with entities engaged in business activities similar to those intended to be conducted by us, including other blank check companies, and, accordingly, may have conflicts of interest in allocating their time and determining to which entity a particular business opportunity should be presented.
  • Management’s flexibility in identifying and selecting a prospective acquisition candidate, along with our management’s financial interest in consummating our initial business combination, may lead management to enter into an acquisition agreement that is not in the best interest of our shareholders.
  • Our executive officers and directors may negotiate employment or consulting agreements with a target business in connection with a particular business combination. 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.
  • The officers and directors of an acquisition candidate may resign upon consummation of our initial business combination. The loss of an acquisition target’s key personnel could negatively impact the operations and profitability of our post-combination business.
  • Past performance by our management team may not be indicative of future performance of an investment in the Company.
  • 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, may be, or 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.
  • 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.
  • Our letter agreement with our Sponsor, officers and directors may be amended without shareholder approval.
