Risk factors and legal proceedings

The risks Allegro Merger Corp. names in Item 1A of its 10-K filed Feb 11, 2026: 35 risks under these headings, as written.4

  • Additionally, if we consummate the Transactions with SeeQC, we will be subject to the risks and uncertainties relating to SeeQC and its business. Such risks and uncertainties will be described in more detail in our future filings with the Securities and Exchange Commission related to such transaction. You should also consider carefully those material risks before making a decision to invest in our securities.
  • Risks Related to Consummating a Merger Transaction
  • The report of our independent registered public accounting firm expresses substantial doubt about our ability to continue as a going concern
  • 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.
  • We have no operating history and no revenue and, accordingly, you have no basis on which to evaluate our ability to achieve our business objective.
  • You will be unable to ascertain the merits or risks of any particular target business’ operations.
  • Because of our limited resources and the significant competition for target businesses, it may be more difficult for us to complete a merger transaction.
  • Subsequent to consummation of a merger transaction, 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 our stock price, which could cause you to lose some or all of your investment.
  • We may issue additional common or preferred stock to complete a merger transaction or under an employee incentive plan after consummation of a merger transaction, which would dilute the interest of our stockholders and likely present other risks.
  • We may issue notes or other debt securities, or otherwise incur substantial debt, to complete a merger transaction, which may adversely affect our financial condition and the value of our stockholders’ investment in us.
  • Resources could be wasted in researching acquisitions that are not consummated, which could materially adversely affect subsequent attempts to locate another target business and consummate a merger transaction.
  • We are dependent upon our officers and directors; the loss of any one or more of them could adversely affect our ability to complete a merger transaction.
The other 24 risks
  • Our officers and directors may in the future become affiliated with entities engaged in business activities similar to those intended to be conducted by us and, accordingly, may have conflicts of interest in determining to which entity a particular business opportunity should be presented.
  • We may engage in a merger transaction with one or more target businesses that have relationships with entities that may be affiliated with our executive officers, directors, or existing stockholders, which may raise potential conflicts of interest.
  • 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 a merger transaction and could even result in our inability to find a target or to consummate a merger transaction.
  • Changes in the market for directors’ and officers’ liability insurance could make it more difficult and more expensive for us to negotiate and complete a merger transaction.
  • Our search for a merger transaction, and any target business with which we ultimately consummate a merger transaction, may be materially adversely affected by new outbreaks, or continuation of any existing outbreaks, of any infectious disease and other events, and the status of debt and equity markets.
  • Risks Related to the Liquidation of the Trust Account
  • If 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 the proceeds from our Trust Account which were distributed to our public stockholders, 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.
  • 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.
  • Risks Related to Owning our Securities
  • Our securities were delisted from the Nasdaq Capital Market, deregistered under Section 12(b) of the Exchange Act, and are not traded on an established trading marked or exchange. Investors will have a limited ability to make transactions in our securities.
  • Our common stock is classified as a “penny stock” under SEC rules, which means that any broker-dealers who wish to make a market in our stock will be subject to additional compliance requirements.
  • We may not hold an annual meeting of stockholders until after we consummate a merger transaction.
  • Changes in laws or regulations, or a failure to comply with any laws and regulations, may adversely affect our business, investments and results of operations.
  • If we are unable to complete a merger transaction and determine to liquidate and dissolve, our warrants and rights will expire worthless.
  • We may amend the terms of the rights in a manner that may be adverse to holders with the approval by the holders of at least 65% of the then outstanding rights.
  • We may amend the terms of the warrants in a manner that may be adverse to holders with the approval by the holders of at least 65% of the then outstanding warrants.
  • A registration statement covering the shares underlying our warrants may not be in place when an investor desires to exercise warrants, thus precluding such investor from being able to exercise its warrants and causing such warrants to expire worthless.
  • We may redeem your unexpired warrants prior to their exercise at a time that is disadvantageous to you, thereby making your warrants worthless.
  • Our ability to require holders of our warrants to exercise such warrants on a cashless basis will cause holders to receive fewer shares upon their exercise of the warrants than they would have received had they been able to exercise their warrants for cash.
  • The grant of registration rights to our initial stockholders and purchasers of private placement units may make it more difficult to complete a merger transaction, and the future exercise of such rights may reduce the market price of our common stock.
  • General Risks
  • The requirements of being a public company may strain our resources and divert management’s attention.
  • Compliance obligations under the Sarbanes-Oxley Act may make it more difficult for us to effectuate a merger transaction, require substantial financial and management resources, and increase the time and costs of completing an acquisition.
  • 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 common stock and could entrench management.
  • Our amended and restated certificate of incorporation provides, subject to limited exceptions, that the Court of Chancery of the State of Delaware will be the sole and exclusive forum for certain stockholder litigation matters, which could limit our stockholders’ ability to obtain a favorable judicial forum for disputes with us or our directors, officers, employees, or stockholders.
  • Risk related to our public and private warrants
  • SEC guidance required us to reconsider the accounting of warrants and led us to conclude that our warrants be accounted for as liabilities rather than as equity and such requirement resulted in a restatement of our previously issued financial statements.
  • Certain of our warrants are accounted for as warrant liabilities and are recorded at fair value upon issuance with changes in fair value each reporting period to be reported in earnings, which may have an adverse effect on the market price of our Common Stock.
