Risk factors and legal proceedings

The risks Protagenic Therapeutics, Inc.\new names in Item 1A of its 10-K filed Aug 14, 2026: 69 risks under these headings, as written.5

  • Risks Related to Our Financial Condition and Capital Requirements
  • The Company’s financial statements have been prepared on a going concern basis, and do not include adjustments that might be necessary if the Company is unable to continue as a going concern.
  • We have a history of losses and expect that losses may continue in the future.
  • We need to obtain financing to continue our operations.
  • If we continue to incur operating losses and fail to obtain the capital necessary to fund our operations, we will be unable to advance our development programs, complete our clinical trials, or bring products to market, or may be forced to reduce or cease operations entirely. In addition, any capital obtained by us may be obtained on terms that are unfavorable to us, our investors, or both.
  • We have a limited operating history, expect to incur significant operating losses, and have a high risk of never being profitable.
  • Unstable market and economic conditions may have serious adverse consequences on our ability to raise funds, which may cause us to cease or delay our operations.
  • Risks Related to Clinical Development and Regulatory Approval
  • Our results to date provide no basis for predicting whether any of our product candidates will be safe or effective, or receive regulatory approval.
  • We may not be able to initiate and complete preclinical studies and clinical trials for our product candidates which could adversely affect our business.
  • The drug development and approval process is uncertain, time-consuming and expensive.
  • The regulatory approval process is costly and lengthy and we may not be able to successfully obtain all required regulatory approvals.
The other 59 risks
  • Even if we receive regulatory approvals for marketing our product candidates, if we fail to comply with continuing regulatory requirements, we could lose our regulatory approvals, and our business would be adversely affected.
  • Even if we are able to obtain regulatory approvals for any of our product candidates, if they exhibit harmful side effects after approval, our regulatory approvals could be revoked or otherwise negatively impacted, and we could be subject to costly and damaging product liability claims.
  • If we experience delays or difficulties in the enrollment of subjects to our clinical trials, our receipt of necessary regulatory approvals could be delayed or prevented, which could materially affect our financial condition.
  • New federal laws or regulations on drug importation could make lower cost versions of our future products available, which could adversely affect our revenues, if any.
  • Failure to obtain regulatory and pricing approvals in foreign jurisdictions could delay or prevent commercialization of our products abroad.
  • It is uncertain whether product liability insurance will be adequate to address product liability claims, or that insurance against such claims will be affordable or available on acceptable terms in the future.
  • If the market opportunities for our current and potential future drug candidates are smaller than we believe they are, our ability to generate product revenues will be adversely affected and our business may suffer.
  • Risks Related to Our Reliance on Third Parties
  • We may not be able to obtain and maintain the third-party relationships that are necessary to develop, commercialize and manufacture some or all our product candidates.
  • We have no experience in sales, marketing and distribution and may have to enter into agreements with third parties to perform these functions, which could prevent us from successfully commercializing our product candidates.
  • Data provided by collaborators and other parties upon which we rely, have not been independently verified and could turn out to be inaccurate, misleading, or incomplete.
  • In certain cases, we may need to rely on a single supplier for a particular manufacturing material or service, and any interruption in or termination of service by such supplier could delay or disrupt the commercialization of our products.
  • We rely on third parties to conduct our non-clinical studies and our clinical trials. If these third parties do not successfully carry out their contractual duties or meet expected deadlines, we may be unable to obtain regulatory approval for or commercialize our current product candidates or any future products, on a timely basis or at all, and our financial condition will be adversely affected.
  • Risks Related to Commercialization of Our Product Candidates
  • We have no experience as a company in commercializing any product. If we fail to obtain commercial expertise, upon product approval by regulatory agencies, our product launch and revenues could be delayed.
  • We may not be able to gain market acceptance of our product candidates, which would prevent us from becoming profitable.
  • We may not be able to manufacture our product candidates in clinical or commercial quantities, which would prevent us from commercializing our product candidates.
  • Our products may not be accepted for reimbursement or properly reimbursed by third-party payers.
  • New federal legislation may increase the pressure to reduce prices of pharmaceutical products paid for by Medicare, which could adversely affect our revenues, if any.
  • Disputes under key agreements or conflicts of interest with our scientific advisors or clinical investigators could delay or prevent development or commercialization of our product candidates.
  • Our competitors and potential competitors may develop products and technologies that make ours less attractive or obsolete.
  • Competition in the biotechnology and pharmaceutical industries may result in competing products, superior marketing of other products and lower revenues or profits for us.
  • Risks Related to Our Intellectual Property
  • We may not be able to maintain our exclusive worldwide license to use and develop PT00114 which could materially affect our business plan.
  • We have to sustain and further build our intellectual property rights.
  • We must comply with our obligations in our intellectual property licenses with third parties.
  • Patent litigation or other litigation in connection with our intellectual property rights may lead to publicity that may harm our reputation and the value of our common stock may decline.
  • Protecting and defending against intellectual property claims may have a material adverse effect on our business.
  • Intellectual property disputes could require us to spend time and money to address such disputes and could limit our intellectual property rights.
  • We may not be able to enforce our intellectual property rights throughout the world.
  • Changes to the patent law in the U.S. and other jurisdictions could diminish the value of patents in general, thereby impairing our ability to protect our product candidates.
  • Obtaining and maintaining our patent protection depends on compliance with various procedural, document submission, fee payment and other requirements imposed by governmental patent agencies, and our patent protection could be reduced or eliminated for non-compliance with these requirements.
  • If we fail to comply with our obligations under any license, collaboration or other intellectual property-related agreements, we may be required to pay damages and could lose intellectual property rights that may be necessary for developing, commercializing and protecting our current or future technologies or drug candidates or we could lose certain rights to grant sublicenses.
  • Risks Related to Our Business Operations and Industry
  • If we are not able to retain our current senior management team and our scientific advisors or continue to attract and retain qualified scientific, technical, and business personnel, our business will suffer.
  • We may encounter difficulties in managing our growth, which could adversely affect our operations.
  • Healthcare reform measures could adversely affect our business.
  • Our business and operations are vulnerable to computer system failures, cyber-attacks or deficiencies in our cyber-security, which could increase our expenses, divert the attention of our management and key personnel away from our business operations and adversely affect our results of operations.
  • Failure to comply with health and data protection laws and regulations could lead to government enforcement actions (which could include civil or criminal penalties), private litigation or adverse publicity and could negatively affect our operating results and business.
  • If we, our CROs or our IT vendors experience security or data privacy breaches or other unauthorized or improper access to, use of, or destruction of personal data, we may face costs, significant liabilities, harm to our brand and business disruption.
  • If we do not comply with laws regulating the protection of the environment and health and human safety, our business could be adversely affected.
  • Risks Associated to our Common Stock
  • If we fail to comply with the continued minimum closing bid requirements of Nasdaq by April 28, 2025 or other requirements for continued listing, including stockholder equity requirements, our common stock may be delisted and the price of our common stock and our ability to access the capital markets could be negatively impacted.
  • Our common stock is a “Penny Stock” subject to specific rules governing its sale to investors that could impact its liquidity.
  • The market price of our common stock may be volatile, and you could lose all or part of your investment.
  • Compliance with the reporting requirements of federal securities laws can be expensive.
  • Applicable regulatory requirements, including those contained in and issued under the Sarbanes-Oxley Act of 2002, may make it difficult for us to retain or attract qualified officers and directors, which could adversely affect the management of its business and its ability to obtain or retain listing of our common stock.
  • If we fail to maintain an effective system of internal controls, we may not be able to accurately report our financial results or detect fraud. Consequently, investors could lose confidence in our financial reporting and this may decrease the trading price of our stock.
  • The price of our common stock may become volatile, which could lead to losses by investors and costly securities litigation.
  • Investors may experience dilution of their ownership interests because of the future issuance of additional shares of our common stock.
  • Our common stock is controlled by insiders
  • We do not intend to pay dividends for the foreseeable future and may never pay dividends.
  • There can be no assurance that we will ever provide liquidity to our investors through a sale of our Company.
  • Our certificate of incorporation allows our board to create new series of preferred stock without further approval by our stockholders, which could adversely affect the rights of the holders of our common stock.
  • Our common stock has been delisted from Nasdaq and now trades only in the over-the-counter market, which has substantially reduced the liquidity and may adversely affect the price of our common stock.
  • There is no assurance that we will be able to relist our common stock on Nasdaq or any other national securities exchange.
  • The application of “penny stock” rules to our common stock could further limit trading activity and the liquidity of our common stock.
  • Delisting may reduce or eliminate analyst coverage and institutional ownership of our common stock.
  • Our delisting impairs our access to the capital markets and could increase the cost and difficulty of raising capital.
  • Our common stock may no longer constitute a “covered security,” which could subject offers and sales to additional state securities law requirements.
  • Our common stock may be removed or otherwise excluded from stock market indices, resulting in forced selling.
  • Our common stock may not be eligible for margin borrowing and could be subject to limitations on electronic clearing and settlement.
  • Our delisting may harm our reputation and our relationships with customers, suppliers, employees, and other stakeholders.
  • The market price of our common stock has been and may continue to be volatile, and the thinner over-the-counter market may make our common stock more susceptible to manipulation.
  • Future sales or issuances of our common stock, including at depressed market prices, could result in substantial dilution and could further depress our stock price.

Legal proceedings

From time to time we may be named in claims arising in the ordinary course of business. As of March 31, 2026, no legal proceedings, government actions, administrative actions, investigations or claims are pending against us or involve us that, in the opinion of our management, could reasonably be expected to have a material adverse effect on our business, financial condition, and results of operations.
