Risk factors and legal proceedings

The risks Azitra, Inc. names in Item 1A of its 10-K filed Feb 27, 2026: 46 risks under these headings, as written.3

  • Risks Relating to Our Business
  • We are an early-stage clinical biopharmaceutical company with limited operating history.
  • We have a history of significant operating losses and anticipate continued operating losses for the foreseeable future.
  • We expect we will need additional financing to execute our business plan and fund operations, which additional financing may not be available on reasonable terms or at all.
  • The clinical and commercial utility of our microbial library and genetic engineering platform is uncertain and may never be realized.
  • Our product candidates are in early-stage clinical trials or early stages of preclinical development, and therefore they will require extensive additional preclinical and clinical testing. Success in preclinical studies or early-stage clinical trials may not be indicative of results in future clinical trials and we cannot assure you that any ongoing, planned or future clinical trials will lead to results sufficient for the necessary regulatory approvals.
  • We will need to grow the size of our organization, and we may experience difficulties in managing this growth.
  • If we are not successful in attracting and retaining highly qualified personnel, we may not be able to successfully implement our business strategy. In addition, the loss of the services of our senior management would adversely impact our business prospects.
  • We currently have no sales and marketing organization. If we are unable to establish satisfactory sales and marketing capabilities or secure a third-party sales and marketing relationship, we may not be able to successfully commercialize any of our product candidates.
  • We will be completely dependent for the foreseeable future on third parties to manufacture our product candidates for commercial sale, and the commercialization of our product candidates could be halted, delayed or made less profitable if those third parties fail to obtain manufacturing approval from the FDA or comparable foreign regulatory authorities, fail to provide us with sufficient quantities of our product candidates or fail to do so at acceptable quality levels or prices.
  • Our business model includes the potential out-licensing of strains from our proprietary microbial library or our product candidates to other biopharmaceutical companies, however technology licensing in the biopharmaceutical industry is a lengthy process and subject to several risks and factors outside of our control, and we cannot forecast our ability to successfully out-license our technology or the length of time it takes to establish a new licensing relationship.
  • If product liability lawsuits are brought against us, we may incur substantial liabilities and may be required to limit commercialization of our product candidates.
The other 35 risks
  • Our internal computer systems, or those of our collaborators or other contractors or consultants, may fail or suffer security breaches, which could result in a material disruption of our product development programs.
  • We face significant competition from other biotechnology and pharmaceutical companies targeting medical dermatological indications, and our operating results will suffer if we fail to compete effectively.
  • Emerging issues related to the development and use of artificial intelligence could give rise to legal or regulatory action, damage our reputation, or otherwise materially harm our business.
  • Risks Related to Product Regulation
  • Our success is entirely dependent on our ability to obtain the marketing approval for our product candidates by the FDA and the regulatory authorities in foreign jurisdictions in which we intend to market our product candidates, of which there can be no assurance.
  • Disruptions at the FDA and other government agencies caused by funding shortages or global health concerns could hinder their ability to hire, retain, or deploy key leadership and other personnel, or otherwise prevent new or modified products from being developed, approved, or commercialized in a timely manner or at all, which could negatively impact our business.
  • Our clinical trials may fail to demonstrate substantial evidence of the safety and efficacy of our product candidates or any future product candidates, which would prevent or delay or limit the scope of regulatory approval and commercialization.
  • Results of preclinical studies of our product candidates may not be predictive of the results of future preclinical studies or clinical trials.
  • Any termination or suspension of, or delays in the commencement or completion of, any necessary studies of any of our product candidates for any indications could result in increased costs to us, delay or limit our ability to generate revenue and adversely affect our commercial prospects.
  • Even if we receive regulatory approval for any of our product candidates, we may not be able to successfully commercialize the product and the revenue that we generate from its sales, if any, may be limited.
  • Even if we obtain marketing approval for any of our product candidates, we will be subject to ongoing obligations and continued regulatory review, which may result in significant additional expense. Additionally, our product candidates could be subject to labeling and other restrictions and withdrawal from the market and we may be subject to penalties if we fail to comply with regulatory requirements or if we experience unanticipated problems with our product candidates.
  • Obtaining and maintaining regulatory approval of our product candidates in one jurisdiction does not mean that we will be successful in obtaining regulatory approval of our product candidates in other jurisdictions.
  • Even though we may apply for orphan drug designation for a product candidate, we may not be able to obtain orphan drug marketing exclusivity.
  • Current and future legislation may increase the difficulty and cost for us to obtain marketing approval of and commercialize our product candidates and affect the prices we may obtain.
  • Third-party coverage and reimbursement and health care cost containment initiatives and treatment guidelines may constrain our future revenues.
  • Our relationships with customers and payors are subject to applicable anti-kickback, fraud and abuse and other healthcare laws and regulations, which, if violated, could expose us to criminal sanctions, civil penalties, exclusion from government healthcare programs, contractual damages, reputational harm and diminished profits and future earnings.
  • Risks Relating to Our Intellectual Property Rights
  • It is difficult and costly to protect our intellectual property rights, and we cannot ensure the protection of these rights.
  • Our product candidates may infringe the intellectual property rights of others, which could increase our costs and delay or prevent our development and commercialization efforts.
  • We may be subject to claims that we have wrongfully hired an employee from a competitor or that we or our employees have wrongfully used or disclosed alleged confidential information or trade secrets of their former employers.
  • Risks Related to Owning Our Common Stock
  • The market price of our shares may be subject to fluctuation and volatility. You could lose all or part of your investment.
  • Our charter limits our ability to issue shares.
  • Our failure to meet the continued listing requirements of the NYSE American could result in a delisting of our common stock.
  • Future capital raises may dilute your ownership and/or have other adverse effects on our operations.
  • Shares eligible for future sale may adversely affect the market for our common stock.
  • We are an “emerging growth company” under the JOBS Act and we cannot be certain if the reduced disclosure requirements applicable to emerging growth companies will make our common stock less attractive to investors.
  • Our status as an “emerging growth company” under the JOBS Act may make it more difficult to raise capital as and when we need it.
  • We have not paid dividends on our common stock in the past and have no immediate plans to pay such dividends.
  • If equity research analysts do not publish research or reports about our business or if they issue unfavorable commentary or downgrade our shares, the price of our shares could decline.
  • We may be at an increased risk of securities class action litigation.
  • Our charter documents and Delaware law may inhibit a takeover that stockholders consider favorable.
  • General Risk Factors
  • Changes in accounting standards and subjective assumptions, estimates and judgments by management related to complex accounting matters may materially impact reporting of our financial condition and results of operations.
  • A potential failure to maintain effective internal control over financial reporting in accordance with Section 404 of the Sarbanes-Oxley Act could have a material adverse effect on our business, financial condition, and results of operations.
  • The limited amount of public company experience of our management team could adversely impact our ability to comply with the reporting requirements of U.S. securities laws, which could have a materially adverse effect on our business.
  • We identified material weaknesses in our internal control over financial reporting, and we may identify additional material weaknesses in the future that may cause us to fail to meet our reporting obligations or result in material misstatements of our financial statements. If we fail to remediate any material weaknesses or if we otherwise fail to establish and maintain effective control over financial reporting, our ability to accurately and timely report our financial results could be adversely affected.
  • We have and will continue to incur significant increased costs as a result of being a public company that reports to the SEC and our management will be required to devote substantial time to meet compliance obligations.
  • Unfavorable geopolitical and macroeconomic developments could adversely affect our business, financial condition or results of operations.

Legal proceedings

As of the date of this report, there are no legal proceedings to which we or our properties are subject. We may be involved, from time to time, in legal proceedings and claims arising in the ordinary course of its business. Such matters are subject to many uncertainties and outcomes and are not predictable with assurance.
