We are a leading clinical-stage biopharmaceutical company focused on the discovery, development and commercialization of gamma-delta T cellular therapy product candidates and gamma-delta T cell engagers ("TCEs") for cancer and autoimmune diseases.

They are naturally occurring immune cells that can intrinsically regulate immune responses and have the ability to differentiate between healthy and diseased tissue.

Risk factors and legal proceedings
The risks IN8BIO, INC. names in Item 1A of its 10-K filed Mar 12, 2026: 71 risks under these headings, as written.5
- Risks Related to Our Financial Position and Capital Needs
- There is substantial doubt regarding our ability to continue as a going concern. We will require substantial additional funding to finance our operations, and if we are unable to raise capital, we could be forced to delay, reduce or explore other strategic options for certain of our development programs, or even terminate our operations.
- Raising additional capital may cause dilution to our stockholders, restrict our operations or require us to relinquish rights to our product candidates.
- A sale of a substantial number of shares of our common stock may cause the price of our common stock to decline.
- Our outstanding warrants may not be exercised and we may not receive any cash proceeds from any exercise of warrants.
- We have incurred significant operating losses since inception and anticipate that we will continue to incur substantial operating losses for the foreseeable future and may never achieve or maintain profitability.
- Our ability to raise capital may be limited by applicable laws and regulations.
- We have a limited operating history and have no products approved for commercial sale, which may make it difficult for you to evaluate the success of our business to date and to assess our future viability.
- Risks Related to the Development of Our Product Candidates
- We are dependent on the successful clinical development, regulatory approval and commercialization of our gamma-delta T cell product candidates. If we are not able to obtain required regulatory approvals, we will not be able to commercialize our product candidates and our ability to generate product revenue will be adversely affected.
- Our product candidates are in early stages of 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.
- Interim, "topline" and preliminary data from our clinical trials that we announce or publish from time to time may change as more patient data become available and are subject to audit and verification procedures that could result in material changes in the final data.
The other 61 risks
- Our DeltEx product candidates utilize novel approaches to cell therapies, including cancer treatment, which presents significant challenges to successfully develop, manufacture and commercialize our product candidates.
- The clinical and commercial utility of our DeltEx platform is uncertain and may never be realized. Additionally, certain aspects of the function and production of gamma-delta T cells are poorly understood or currently unknown and may only become known through further preclinical and clinical testing.
- Clinical product candidate development involves a lengthy and expensive process with uncertain outcomes. We may incur additional costs and encounter substantial delays or difficulties in our clinical trials.
- Development of a product candidate intended for use in combination with an already approved therapy may present increased complexity and more or different challenges than development of a product candidate for use as a single agent or monotherapy.
- If we encounter difficulties in enrolling patients in our clinical trials, our clinical development activities could be delayed or otherwise adversely affected.
- Serious adverse events, undesirable side effects or other unexpected properties of our product candidates may be identified during development or after approval, which could lead to the discontinuation of our clinical development programs, refusal by regulatory authorities to approve our product candidates or, if discovered following marketing approval, revocation of marketing authorizations or limitations on the use of our product candidates thereby limiting the commercial potential of such product candidate.
- We may not be able to file IND applications to commence additional clinical trials on the timelines we expect, and even if we are able to, the FDA may not permit us to proceed.
- We may seek Breakthrough Therapy, RMAT or Fast Track designations and may pursue accelerated approval for some or all of our current product candidates, but we may be unable to obtain such designations or, where obtained, we may be unable to maintain Breakthrough Therapy or RMAT designation or obtain or maintain the benefits associated with such designations.
- Although we have received orphan drug designation for INB-400 in the past and may continue to seek orphan drug designation for some or all of our current or future product candidates, we may be unsuccessful or may be unable to maintain the benefits associated with orphan drug designation, including the potential for supplemental market exclusivity.
- We may not be able to identify or discover other product candidates and may fail to capitalize on programs or product candidates that may present a greater commercial opportunity or for which there is a greater likelihood of success.
- Public opinion and scrutiny of our competitors, cell-based immunotherapy, T cell engagers, and genetic modification approaches may impact public perception of our company and product candidates, or may adversely affect our ability to raise capital, conduct our business and our business plans.
- We face significant competition, and many of our competitors have substantially greater experience and resources than we have.
- We expect the product candidates we develop will be regulated as biologics, and therefore they may be subject to competition sooner than anticipated.
- Risks Related to Manufacturing and Our Dependence on Third Parties
- Our manufacturing processes are complex, and we may encounter difficulties in production, which would delay or prevent our ability to provide a sufficient supply of our product candidates for future clinical trials or commercialization, if approved.
- We may rely on third-party contractors or contract development manufacturing organization for the manufacturing of our product candidates, and failure by those parties to adequately perform their obligations could harm our business.
- We currently store our gamma-delta T cells and biologic correlative and research specimens from clinical trials and development programs and clinical lentivectors at our research and development facilities and at the facilities of our clinical and/or manufacturing partners, and any damage or loss to our storage freezers and/or facilities from natural disasters or otherwise would cause delays in replacement, and our business could suffer.
- We are currently dependent on a single third-party supplier for manufacture of our automated manufacturing device and our lentiviral vectors for our cellular therapies. These are critical products required for the manufacturing of our product candidates, including INB-100, INB-200 and INB-400. Any damage or loss to the ability of our suppliers to deliver supplies in a timely manner could cause delays in manufacturing, and our clinical trials and our business could suffer.
- We rely on third-party healthcare professionals to administer gamma-delta T cells to patients, and our business could be harmed if these third parties administer these cells incorrectly.
- We believe we may require an updated and validated protocol for commercial-scale expansion and manufacturing of gamma-delta T cells for conducting pivotal trials and for commercialization of our product candidates, if approved.
- We have not yet developed commercial-scale infrastructure for freezing and thawing large quantities of gamma-delta T cells, which we believe will be required for the storage and distribution of our gamma-delta T cell product candidates at commercial scale.
- Our business involves the use of hazardous materials and we and our third-party manufacturers and suppliers must comply with environmental, health and safety laws and regulations, which can be expensive and restrict or interrupt our business.
- We intend to partner with third parties, such as academic institutions and CROs, to conduct, supervise and monitor some of our preclinical studies and clinical trials, and if those third parties perform in an unsatisfactory manner, it may harm our business and delay or impair our ability to obtain regulatory approval or otherwise commercialize our product candidates.
- Our employees, principal investigators, consultants and commercial partners may engage in misconduct or other improper activities, including noncompliance with regulatory standards and requirements and insider trading.
- 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 advanced, developed, cleared or approved or commercialized in a timely manner or at all, which could negatively impact our business.
- Risks Related to Our Intellectual Property
- Licensing of intellectual property is of critical importance to our business and involves complex legal, business and scientific issues. If we breach our license agreements with the University of Alabama at Birmingham Research Foundation, Children’s Healthcare of Atlanta, Inc. and Emory University, or any of the other agreements under which we acquired, or will acquire, the intellectual property rights to our product candidates, we could lose the ability to continue the development and commercialization of the related product.
- If we are unable to obtain and maintain patent protection for our product candidates and technology, or if the scope of the patent protection obtained is not sufficiently broad or robust, our competitors could develop and commercialize products and technology similar or identical to ours, and our ability to successfully commercialize our product candidates and technology may be adversely affected.
- Obtaining and maintaining our patent rights depends on compliance with various procedural, document submission, fee payment and other requirements imposed by government patent agencies, and our patent protection could be reduced or eliminated for noncompliance with these requirements.
- Patent terms may be inadequate to protect our competitive position on our product candidates for an adequate amount of time.
- Third parties may initiate legal proceedings alleging that we are infringing, misappropriating or otherwise violating their intellectual property rights and/or trademark, the outcome of which would be uncertain and could have a negative impact on the success of our business.
- We may be subject to claims asserting that our employees, consultants or advisors have wrongfully used or disclosed alleged trade secrets of their current or former employers or claims asserting ownership of what we regard as our own intellectual property.
- We may be involved in lawsuits to protect or enforce our patents, the patents of our licensors or our other intellectual property rights, which could be expensive, time-consuming and unsuccessful.
- Changes in U.S. patent law or the patent law of other countries or jurisdictions could diminish the value of patents in general, thereby impairing our ability to protect our current and any future product candidates.
- We may not be able to protect our intellectual property rights throughout the world, which could negatively impact our business.
- Reliance on third parties requires us to share our trade secrets, which increases the possibility that a competitor will discover them or that our trade secrets will be misappropriated or disclosed.
- If we are unable to protect the confidentiality of our trade secrets, our business and competitive position would be harmed.
- Any trademarks we may obtain may be infringed or successfully challenged, resulting in harm to our business.
- Intellectual property rights do not necessarily address all potential threats to our business.
- Risks Related to Our Business Operations, Employee Matters and Managing Growth
- We plan to expand our organization in the future, and we may experience difficulties in managing this growth, which could disrupt our operations.
- We may explore strategic collaborations that may not have the intended benefits or never materialize, or we may be required to relinquish important rights to and control over the development and commercialization of our product candidates to any future collaborators.
- If our information technology systems, or those of the third parties with whom we work, or our data, are or were compromised, we could experience adverse consequences resulting from such compromise, including but not limited to, a significant disruption of our product development programs and our ability to operate our business effectively, regulatory investigations or actions, litigation, fines and penalties, reputational harm, loss of revenue or profits, and other adverse consequences.
- Our ability to use our net operating losses to offset future taxable income may be subject to certain limitations.
- There are risks inherent in our business that may subject us to potential product liability suits and other claims, which may require us to engage in expensive and time-consuming litigation or pay substantial damages and may harm our reputation and reduce the demand for our product.
- Risks Related to Commercialization and Regulatory Compliance
- Even if we obtain regulatory approvals for our product candidates, they will remain subject to ongoing regulatory oversight.
- Even if any product candidate receives marketing approval, it may fail to achieve market acceptance by physicians, patients, third-party payors or others in the medical community necessary for commercial success.
- If we are unable to establish sales and marketing capabilities or enter into agreements with third parties to market and sell our product candidates, we may not be successful in commercializing them, if and when they are approved.
- Even if we obtain and maintain approval for our product candidates from the FDA, we may never obtain approval outside the United States, which would limit our market opportunities.
- If we commercialize our product candidates outside the United States, a variety of risks associated with international operations could harm our business.
- Our relationships with customers, physicians, and third-party payors are subject, directly or indirectly, to federal and state healthcare fraud and abuse laws, including anti-kickback and false claims laws, transparency laws, and other healthcare laws and regulations. If we are unable to comply, or have not fully complied, with such laws, we could face substantial penalties.
- Coverage and adequate reimbursement may not be available for our product candidates, which could make it difficult for us to sell profitably, if approved.
- Healthcare legislative reform measures may have a negative impact on our business and results of operations.
- The FDA’s ability to review and approve new products may be hindered by a variety of factors, including budget and funding levels, ability to hire and retain key personnel, statutory, regulatory and policy changes and global health concerns.
- Our (or the third parties with whom we work) actual or perceived failures to comply with applicable data privacy and security obligations, including laws, regulations, contractual obligations, industry standards and other obligations could lead to regulatory investigations or actions, litigation (including class claims), fines and penalties, disruptions of our business operations, reputational harm, loss of revenue or profits, and other adverse business consequences.
- Risks Related to the Ownership of Our Common Stock
- An active trading market for our common stock may not be sustained, and you may not be able to sell your shares quickly or at the market price.
- The market price of our common stock is volatile and may fluctuate substantially, and you could lose all or part of your investment.
- Provisions in our corporate charter documents and under Delaware law could make an acquisition of us, which may be beneficial to our stockholders, more difficult and may prevent attempts by our stockholders to replace or remove our current management.
- Our amended and restated certificate of incorporation provides that the Court of Chancery of the State of Delaware will be the exclusive forum for substantially all disputes between us and our stockholders, which could limit our stockholders’ ability to obtain a favorable judicial forum for disputes with us or our directors, officers or employees.
- General Risk Factors
- Unstable market and economic conditions, including as a result of increases in inflation, the price of oil, and interest rates, tariffs and trade wars, geopolitical tensions such as wars and terrorism and future U.S. government shutdowns, may have serious adverse consequences on our business, financial condition and share price.
- If research analysts do not publish research or reports, or publish unfavorable research or reports, about us, our business or our market, our stock price and trading volume could decline.
- We will continue to incur increased costs as a result of operating as a public company, and our management will continue to be required to devote substantial time to new compliance initiatives.
- 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 price of our common stock.
- Our disclosure controls and procedures may not prevent or detect all errors or acts of fraud.
Legal proceedings
From time to time, we may become involved in various legal proceedings arising in the ordinary course of our business. We are not currently a party to any material legal proceedings that we believe could have a material adverse effect on our business, operating results or financial condition.
