Risk factors and legal proceedings
The risks Zura Bio Ltd names in Item 1A of its 10-K filed Mar 19, 2026: 74 risks under these headings, as written.4
- Risks Related to Our Limited Operating History, Financial Position and Capital Requirements
- We have a limited operating history, have not completed any clinical trials, and have not taken a product through to commercialization.
- We have incurred losses since inception, and we expect to incur significant losses for the foreseeable future and may not be able to achieve or sustain profitability in the future. We have not generated any revenue from the ZB Assets and may never generate revenue or become profitable.
- Our recurring losses from operations and financial condition could raise substantial doubt about our ability to continue as a going concern.
- If we are unable to raise capital when needed, or on acceptable terms, we may be forced to delay, reduce and/or eliminate one or more of our development programs or future commercialization efforts.
- Due to the significant resources required for the development of the ZB Assets, we must prioritize the pursuit of treatments for certain indications. We may expend our limited resources to pursue a particular indication and fail to capitalize on indications that may be more profitable or for which there is a greater likelihood of success.
- We may in the future license additional assets, which may require us to expend additional resources and raise additional capital.
- Risks Related to Anticipated Timing for Initiation, Enrollment, and Completion of Any Planned or Future Clinical Trials
- We may not be able to initiate clinical trials if drug product is not timely available at clinical trial sites.
- Risks Related to the Clinical Development and Commercialization of Our Product Candidates
- We have never successfully completed the regulatory approval process for any product candidates and we may be unable to do so for any product candidates we develop.
- We are substantially dependent on the success of the ZB Assets, and our ongoing and anticipated clinical trials of the ZB Assets may not be successful.
The other 63 risks
- The results of preclinical studies and early clinical trials of the ZB Assets may not be predictive of the success of our later clinical trials, and the results of our clinical trials may not satisfy the requirements of the FDA, EMA, or other foreign regulatory authorities.
- Preclinical and clinical development involves a lengthy and expensive process with uncertain outcomes, and results of earlier studies and trials may not be predictive of future clinical trial results.
- Preliminary, interim data from our clinical trials that we announce or publish may change as more patient data become available and are subject to audit and verification procedures.
- We may develop the ZB Assets in combination with other therapies, which exposes us to additional risks related to other agents or active pharmaceutical or biological ingredients used in combination with our product candidates.
- If the FDA or other regulatory authorities revoke their approval of these other therapies or revoke their approval of, or if safety, efficacy, manufacturing or supply issues arise with, the therapies we choose to evaluate in combination with any product candidate we develop, we may be unable to obtain approval.
- The ZB Assets may have a safety profile that could prevent regulatory approval, marketing approval or market acceptance, or limit commercial potential.
- Risks Related to our Dependence on Third Parties or Their Actions
- We intend to rely on third parties to conduct, supervise, and monitor our preclinical studies and clinical trials, and if those third parties perform in an unsatisfactory manner, it may harm our business.
- We do not have our own manufacturing capabilities and will rely on third parties to produce clinical and commercial supplies of our product candidates. Reliance on third parties increases the risk that we will not have sufficient quantities of our product candidates or such quantities at an acceptable cost.
- Risks Related to Our Intellectual Property
- Our business relies on certain licensing rights from Lilly for tibulizumab that can be terminated in certain circumstances. If we breach the agreement, or if we are unable to satisfy our obligations under which we license rights to tibulizumab from Lilly, we could lose the ability to develop and commercialize tibulizumab.
- Our business relies on certain licensing rights from Pfizer for crebankitug that can be terminated in certain circumstances. If we breach the agreement, or if we are unable to satisfy our obligations under which we license rights to torudokimab from Pfizer, we could lose the ability to develop and commercialize crebankitug.
- Our business relies on certain licensing rights from Lilly for torudokimab that can be terminated in certain circumstances. If we breach the agreement, or if we are unable to satisfy our obligations under which we license rights to torudokimab from Lilly, we could lose the ability to develop and commercialize torudokimab.
- Intellectual property disputes may impact our business and/or our ability to develop and commercialize the ZB Assets.
- Our ability to protect our patents and other proprietary rights is uncertain, exposing us to the possible loss of competitive advantage.
- We have limited geographical protection with respect to our licensed patents and may not be able to protect our intellectual property rights throughout the world.
- 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 if we fail to comply with these requirements.
- Issued patents covering one or more of our product candidates could be found invalid or unenforceable.
- We may not be able to maintain or enforce trade secret protection for our product candidates.
- We may be subject to damages resulting from claims that we or our employees have wrongfully used or disclosed confidential information of our competitors or are in breach of non-competition or non-solicitation agreements with our competitors.
- Patent terms may not protect our competitive position with respect to the ZB Assets for an adequate amount of time.
- If we do not obtain patent term extensions in the United States under the Hatch-Waxman Act and in foreign countries under similar legislation, our business may be materially harmed.
- Changes to patent laws in the United States and other jurisdictions could diminish the value of patents in general, thereby impairing our ability to protect or capitalize on the ZB Assets.
- We may not identify relevant third-party patents or may incorrectly interpret the relevance, scope or expiration of a third-party patent, which might adversely affect our ability to develop and market the ZB Assets.
- We may be subject to claims challenging the inventorship or ownership of our patents and other intellectual property.
- We may be subject to patent infringement claims or may need to file claims to protect our intellectual property, which could result in substantial costs and liability and prevent us from commercializing the ZB Assets.
- Our license from Pfizer is subject to retained rights.
- Our licenses from Lilly are subject to retained rights.
- We may not be able to effectively secure first-tier technologies when competing against other companies or investors.
- Numerous factors may limit any potential competitive advantage provided by our intellectual property rights.
- If approved, our product candidates that are regulated as biologics may face competition from biosimilars or interchangeables approved through an abbreviated regulatory pathway.
- Risks Related to Regulatory and Legal Compliance
- The regulatory approval processes of the FDA, EMA, and other foreign regulatory authorities are complex, time-consuming and inherently unpredictable. If we are not able to obtain, or if there are delays in obtaining, required regulatory approvals for the ZB Assets, we may not be able to commercialize, or may be delayed in commercializing, the ZB Assets, and our ability to generate revenue will be materially impaired.
- Of the large number of products in development, only a small percentage successfully complete the FDA, EMA, or foreign regulatory approval processes and are commercialized. The lengthy approval process as well as the unpredictability of future clinical trial results may result in our failing to obtain regulatory approval to market the ZB Assets, which would significantly harm our business, results of operations and prospects.
- We will be subject to extensive ongoing regulatory obligations and continued regulatory review, which may result in significant additional expense and we may be subject to penalties if we fail to comply with regulatory requirements or experience unanticipated problems with the ZB Assets.
- Due to unfavorable pricing regulations and/or third-party coverage and reimbursement policies, we may not be able to offer the ZB Assets at competitive prices which would seriously harm our business.
- The FDA, EMA and other regulatory agencies actively enforce the laws and regulations prohibiting the promotion of off-label uses.
- Our employees, independent contractors, consultants, commercial collaborators, principal investigators, CROs, suppliers and vendors may engage in misconduct or other improper activities, including noncompliance with regulatory standards and requirements.
- Our business operations and current and future arrangements with investigators, healthcare professionals, consultants, third-party payors, patient organizations and customers will be subject to applicable healthcare regulatory laws, which could expose us to penalties.
- The size of the potential market for the ZB Assets is difficult to estimate and, if any of our assumptions are inaccurate, the actual markets for our product candidates may be smaller than our estimates.
- Healthcare legislative and regulatory reform discourse and potential or enacted measures may have a material adverse impact on our business and results of operations and legislative or political discussions surrounding the desire for and implementation of pricing reforms may adversely impact our business.
- If we fail to comply with environmental, health and safety laws and regulations, we could become subject to fines or penalties or incur costs that could have a material adverse effect on the success of our business.
- We are subject to laws and regulations related to privacy, data protection, information security and consumer protection across different markets where we conduct our business. Our actual or perceived failure to comply with such obligations could harm our business.
- International trade policies, including tariffs, sanctions and trade barriers may adversely affect our business, financial condition, results of operations and prospects.
- Risks Related to Our Business Operations, Employee Matters, and Managing Growth
- We are dependent on our key personnel and anticipate hiring additional key personnel. If we are not successful in attracting and retaining qualified personnel, including consultants, we may not be able to successfully implement our business strategy.
- We rely on third parties, including consultants, independent clinical investigators and CROs to conduct and sponsor some of the clinical trials of our product candidates. Any failure by a third party to meet its obligations with respect to the clinical development of our product candidates may delay or impair our ability to obtain regulatory approval for our product candidates.
- In order to successfully implement our plans and strategies, we will need to grow the size of our organization and we may experience difficulties in managing this growth.
- Our internal computer systems, or those of any of the third parties with whom we work (including CROs, manufacturers, other contractors or consultants or potential future collaborators), may fail or suffer security or data privacy breaches or other unauthorized or improper access to, use of, or destruction of our proprietary or confidential data, employee data or personal data, which could result in additional costs, loss of revenue, significant liabilities, harm to our brand and material disruption of our operations.
- We currently rely, and plan to rely in the future, on third parties to conduct and support our preclinical studies and clinical trials. If these third parties do not properly and successfully carry out their contractual duties or meet expected deadlines, we may not be able to obtain regulatory approval of or commercialize the ZB Assets.
- We intend to rely on third parties to manufacture the ZB Assets. There can be no assurance that we will successfully negotiate future agreements with third-party manufacturers for the ZB Assets on acceptable terms or at all. Our business could be adversely affected if the third-party manufacturers are unable to produce the ZB Assets, fail to provide us with sufficient quantities of the ZB Assets or fail to do so at acceptable quality levels or prices.
- We may, in the future, form or seek collaborations or strategic alliances or enter into licensing arrangements, and we may not realize the benefits of such collaborations, alliances or licensing arrangements.
- Our financial condition, results of operations and business reputation could be adversely affected by our recent internal review of certain agreements and other matters.
- The increasing use of social media platforms presents new risks and challenges.
- Our disclosure controls and procedures may not prevent or detect all errors or acts of fraud.
- We may identify material weaknesses in our internal control over financial reporting in the future or fail to maintain an effective system of internal control over financial reporting, which may result in material misstatements of our consolidated financial statements or cause us to fail to meet periodic reporting obligations.
- If we fail to maintain an effective system of disclosure controls and internal control over financial reporting, our ability to produce timely and accurate financial statements or comply with applicable regulations could be impaired, which may adversely affect investor confidence in Zura and, as a result, the market price of our ordinary shares.
- Increasing regulatory focus on privacy and security issues and expanding laws and regulatory requirements could impact our business models and expose us to increased liability.
- We face substantial competition, which may result in others discovering, developing, licensing or commercializing products before or more successfully than we do.
- Public health crises such as pandemics or similar outbreaks have affected and could continue to seriously and adversely affect our preclinical studies and anticipated clinical trials, business, financial condition and results of operations.
- Our business, operations, financial position, and clinical development plans and timelines could be materially adversely affected by international conflicts and economic sanctions.
- Risks Related to Ownership of Our Class A Ordinary Shares
- The market price of our securities may be volatile and may decline in the future.
- We have not paid cash dividends in the past and we do not expect to pay cash dividends in the foreseeable future. Any return on investment may be limited to the capital appreciation, if any, of our Class A Ordinary Shares.
- Future sales and/or issuances of our securities could result in additional dilution of the percentage ownership of our existing shareholders and could cause our share price to fall.
- If certain holders of our Class A Ordinary Shares sell a significant portion of their securities, it may negatively impact the market price of our Class A Ordinary Shares and such holders still may receive significant proceeds.
- Our operating results have and may continue to fluctuate significantly.
- The absence, reduction, or unfavorable nature of securities or industry analyst coverage of our business, as well as unfavorable third‑party reports or commentary and the existence of pre‑funded warrants, could adversely affect the market price and trading volume of our Class A ordinary shares.
