Risk factors and legal proceedings

The risks Pasithea Therapeutics Corp. names in Item 1A of its 10-K filed Mar 30, 2026: 43 risks under these headings, as written.3

  • Risks Related to Our Financial Position and Need for Additional Capital
  • We have a limited operating history and have no products or services approved for commercial sale, which may make it difficult for you to evaluate our current business and predict our future success and viability.
  • We have a history of losses and may not be able to achieve profitability going forward.
  • We will require additional capital to fund our operations, and if we fail to obtain necessary financing, we may not be able to complete the development and commercialization of our drugs.
  • Raising additional capital may cause dilution to our stockholders, restrict our operations or require us to relinquish rights to our technologies or product candidates.
  • Changes in U.S. tax law may materially adversely affect our financial condition, results of operations and cash flows.
  • Our ability to use our net operating losses and other tax attributes may be limited.
  • Unfavorable global economic conditions and adverse developments with respect to financial institutions and associated liquidity risk could adversely affect our business, financial condition and stock price.
  • Risks Related to Development, Clinical Testing, Manufacturing, Regulatory Approval and Commercialization
  • Clinical trials are expensive, time-consuming and difficult to design and implement, and involve an uncertain outcome.
  • Our industry is subject to extensive regulatory obligations and policies that may be subject to change, including due to judicial challenges.
  • Our choice of product candidates and our development plans for our product candidates are subject to change based on a variety of factors, some of which may be out of our control, and if we abandon development of a product candidate we may not be able to develop or acquire a replacement product candidate.
The other 32 risks
  • The regulatory approval processes of the FDA and comparable foreign authorities are lengthy, time consuming and inherently unpredictable, and if we are ultimately unable to obtain regulatory approval for our product candidates, our business will be substantially harmed.
  • Approval may be delayed or denied because we cannot satisfy the FDA’s Chemistry, Manufacturing and Control Requirements.
  • We may encounter substantial delays in our planned clinical trials or may not be able to conduct or complete our clinical trials on the timelines we expect, if at all.
  • We conduct certain of our clinical trials for our product candidates outside of the U.S. which, among other risks, exposes us to the possibility that the FDA and other comparable foreign regulatory authorities may not accept data from such trials, in which case our development plans will be delayed, which could materially harm our business.
  • Our preclinical programs may experience delays or may never advance to clinical trials, which would adversely affect our ability to obtain regulatory approvals or commercialize these programs on a timely basis or at all.
  • We may attempt to secure approval from the FDA or comparable foreign regulatory authorities through an expedited review program, and if we are unable to do so, then we could face increased expense to obtain, and delays in the receipt of necessary marketing approvals.
  • We may seek Orphan Drug Designation for our product candidates, and we may be unsuccessful or may be unable to maintain the benefits associated with Orphan Drug Designation, including the potential for market exclusivity.
  • If any of our product candidates are approved for marketing and commercialization and we have not developed or secured third-party marketing, sales and distribution capabilities, we will be unable to successfully commercialize such products and may not be able to generate product revenue.
  • The FDA and other regulatory agencies actively enforce the laws and regulations prohibiting pre-approval promotion and the promotion of off-label uses.
  • Our business activities may be subject to the U.S. Foreign Corrupt Practices Act, or the FCPA, and similar anti-bribery and anti-corruption laws of other countries in which we operate, as well as U.S. and certain foreign export controls, trade sanctions, and import laws and regulations. Compliance with these legal requirements could limit our ability to compete in foreign markets and subject us to liability if we violate them.
  • Our business involves the use of hazardous materials and we and our third-party manufacturers and suppliers must comply with environmental laws and regulations, which can be expensive and restrict how we do business.
  • Disruptions in the global economy and supply chains may have a material adverse effect on our business, financial condition and results of operations.
  • Pursuant to the AlloMek Agreement, the AlloMek Sellers have a right to repurchase certain assets and specified intellectual property from us in the event of a change of control and if we fail to meet certain obligations regarding development and commercialization.
  • Risks Related to Our Dependence on Third Parties
  • We rely completely on third parties, including WuXi, to supply drug substance and manufacture drug product for our clinical trials and preclinical studies. We intend to rely on other third parties to produce commercial supplies of product candidates, and our dependence on third parties could adversely impact our business.
  • We have in the past relied and expect to continue to rely on third-party CROs and other third parties to conduct and oversee our research programs, preclinical studies, planned clinical trials and other aspects of product development. If these third parties do not meet our requirements or otherwise operate as required, we may not be able to satisfy our contractual obligations or obtain regulatory approval for, or commercialize, our product candidates when expected or at all.
  • If we enter into collaborations with third parties to develop or commercialize our product candidates, our prospects with respect to those product candidates will depend in significant part on the success of those collaborations.
  • Changes in U.S. and international trade policies, particularly with respect to China, may adversely impact our business and operating results.
  • Risks Related to Our Securities
  • The prices of our Common Stock and Warrants may be volatile, and you could lose all or part of your investment.
  • We could be negatively affected as a result of the actions of activists or hostile stockholders.
  • Our Warrants may not have any value.
  • A Warrant does not entitle the holder to any rights as common stockholders until the holder exercises the Warrant for a share of our Common Stock.
  • If securities or industry analysts do not publish research or reports, or if they publish adverse or misleading research or reports, regarding us, our business or our market, the price and trading volume of our Common Stock and Warrants could decline.
  • Our quarterly operating results may fluctuate significantly or may fall below the expectations of investors or securities analysts, each of which may cause our stock price to fluctuate or decline.
  • If we fail to maintain an effective system of internal control over financial reporting, we may not be able to accurately report our financial results or prevent fraud. As a result, stockholders could lose confidence in our financial and other public reporting, which would harm our business and the trading prices of our Common Stock and Warrants.
  • We are an “emerging growth company,” and we cannot be certain if the reduced reporting requirements applicable to emerging growth companies will make our Common Stock and Warrants less attractive to investors.
  • The requirements of being a public company may strain our resources, resulting in more litigation and divert management’s attention.
  • We may be subject to securities litigation, which is expensive and could divert management attention.
  • We do not currently intend to pay dividends on our Common Stock and, consequently, your ability to achieve a return on your investment will depend on appreciation of the value of our Common Stock.
  • Provisions in our Certificate of Incorporation and Bylaws and Delaware law might discourage, delay or prevent a change in control of our company or changes in our management and, therefore, depress the market price of our securities.
  • Certain beneficial owners might have control over us which could delay or prevent a change in corporate control or result in the entrenchment of management and/or the Board.
  • Exchange rate fluctuations may materially affect our results of operations and financial condition.
  • Failure to comply with The Nasdaq Capital Market continued listing requirements may result in our Common Stock and/or Warrants being delisted from The Nasdaq Capital Market.
