We believe the future treatment for obesity lies not just in overall weight loss, but in the quality, durability, and tolerability of weight loss. Current interventional therapies, such as glucagon-like peptide-1 (“GLP-1”) receptor agonists have ushered in a breakthrough era, yet challenges remain: muscle loss, fat regain after treatment cessation, and long-term tolerability. We are developing next-generation therapies designed with the goal of meeting these unmet needs, by leveraging AI-guided antibody design, advanced screening technologies and deep expertise in biologics development.5 From its latest annual report

Risk factors and legal proceedings
The risks iBio, Inc. names in Item 1A of its 10-K filed Aug 28, 2026: 63 risks under these headings, as written.5
- Risks Related to Our Business, Financial Position and Capital Requirements
- Risks Related to the Development and Commercialization of Our Technologies and Product Candidates
- Risks Related to Dependence on Third Parties
- Risks Related to Intellectual Property
- Risks Related to iBio’s Operations
- Risks Related to Our Common Stock
- Detailed Risk Factors
- We have a limited operating history developing precision antibody therapeutics, which may limit the ability of investors to make an informed investment decision.
- We have incurred significant losses since our inception. We expect to incur losses during our next fiscal year, we do not anticipate generating significant revenue for several years and may never achieve or maintain profitability.
- We anticipate that our expenses will increase in the future.
- We will need additional funding to fully execute our business plan, which funding may not be available on commercially acceptable terms or at all. If we are unable to raise capital when needed, we may be forced to delay, reduce or eliminate the commercialization of our development and manufacturing services and efforts for our product development programs.
- The actual amount of funds we will need to operate is subject to many risk factors, some of which are beyond our control.
The other 57 risks
- We currently have a limited operating history developing precision antibodies, no products approved for commercial sale, have no significant source of revenue and may never generate significant revenue.
- We currently have a limited number of product candidates in early stages of pre-clinical development and are dependent on the success of these product candidates, which requires significant clinical testing before seeking regulatory approval. If our product candidates do not receive regulatory approval or are not successfully commercialized, our business may be harmed.
- We may expend our limited resources to pursue a particular technology or product candidate and fail to capitalize on technologies or product candidates that may be more profitable or for which there is a greater likelihood of success.
- Preclinical and clinical development involves a lengthy and expensive process, with an uncertain outcome. We or our collaborators may incur additional costs or experience delays in completing, or ultimately be unable to complete, the development and commercialization of our current product candidates or any future product candidates, which could materially harm our business.
- Clinical trials are very expensive, time-consuming, and difficult to design and implement.
- Neither we nor our clients, collaborators or potential licensees will be able to commercialize product candidates based on our technologies and services if preclinical studies do not produce successful results or clinical trials do not demonstrate safety and efficacy in humans.
- If we, or our clients and collaborators, are not able to obtain, or if there are delays in obtaining, required regulatory approvals, we, or our clients and collaborators, will not be able to develop or commercialize our, or third-party, product candidates or will not be able to do so as soon as anticipated, and our ability to generate revenue will be materially impaired.
- Alternative technologies may supersede our technologies or make them noncompetitive, which would harm our ability to generate future revenue.
- The results or success of preclinical studies and early-stage clinical trials of our product candidates may not be predictive of future results or replicated in later preclinical studies or clinical trials of our product candidates in the same indications or other indications.
- Interim, initial, or preliminary results from our clinical trials that we announce or publish from time to time may change (e.g., from positive safety or efficacy results to poor or negative safety or efficacy results) as more patient data become available and are subject to additional audit, validation and verification procedures that could result in material changes in the final data.
- Delays or difficulty in the enrollment of patients in any or all of our clinical trials could increase our development costs and delay completion of our clinical trials and associated regulatory submissions.
- Our Phase 1 clinical trial of IBIO-600 is subject to significant risks that could delay or prevent further development of this product candidate.
- We are conducting clinical studies for IBIO-600 outside of the United States, and may conduct our clinical studies for IBIO-610 and our other product candidates outside of the United States. The FDA and other foreign equivalents may not accept data from such studies, in which case our development plans will be delayed, which could materially harm our business.
- Conducting clinical trials in Australia exposes us to additional regulatory, operational and legal risks that could delay development of our product candidates and increase our costs.
- Our product candidates may exhibit undesirable side effects when used alone or in combination with other approved pharmaceutical products, which may delay or preclude its development or regulatory approval or limit its use if ever approved.
- Product liability lawsuits against us could cause us to incur substantial liabilities and to limit commercialization of any products that we may develop.
- Our most advanced product candidates depend on intellectual property licensed from third parties and termination of any of these or future licenses could result in the loss of significant rights, which could adversely affect our business, results of operations and financial condition.
- Our AI/ML platform leverages internal data as well as data from third parties. Defects in, or loss of access to, our databases or those of third parties may impair our ability to discover additional targets and develop our product candidates.
- For any clinical product candidates we may develop we will rely on third-party contract manufacturers. Any manufacturing problems experienced by us could result in a delay or interruption in the supply of our clinical product candidate until the problem is cured or until we locate and qualify an alternative source of manufacturing and supply.
- If we are unable to establish new collaborations and maintain both new and existing collaborations, or if these collaborations are not successful, our business could be adversely affected.
- If third parties on whom we or our licensees will rely for the conduct of preclinical studies and clinical trials do not perform as contractually required or as we expect, we may not be able to obtain regulatory approval for or commercialize our product candidates and our business may suffer.
- We rely on third parties to supply the raw materials needed to operate our research and development activities and do not have any long-term commitments from such suppliers.
- Our use of hazardous and biological materials could result in us being liable for damages.
- Any claims beyond our insurance coverage limits, or that are otherwise not covered by our insurance, may result in substantial costs and a reduction in our available capital resources.
- We may be subject to various litigation claims and legal proceedings.
- If we or our licensors are unable to obtain and maintain patent protection for our technology and products, or if the scope of the patent protection obtained is not sufficiently broad, competitors could develop and commercialize technology and products similar or identical to ours, and our ability to successfully commercialize our technology and products may be impaired.
- If we are unable to protect the confidentiality of our partners’ or collaborators’ proprietary information, we may be subject to claims.
- We may become involved in lawsuits to protect or enforce our patents or other intellectual property, which could be expensive, time-consuming and ultimately unsuccessful.
- Patent terms may be inadequate to protect our competitive position on our product candidates for an adequate amount of time.
- If we are unable to protect our trade secrets, our business and competitive position would be harmed.
- We may be subject to claims challenging the inventorship of our patent filings and other intellectual property.
- Intellectual property rights do not necessarily address all potential threats to our competitive advantage.
- We may not be able to protect our intellectual property rights throughout the world.
- If we should fail to comply with various patent laws our patent protection could be reduced or eliminated.
- Changes in patent law, including recent patent reform legislation, could increase the uncertainties and costs surrounding the prosecution of our patent applications and the enforcement or defense of our issued patents.
- The loss of one or more of our executive officers or key employees or an inability to attract and retain highly skilled employees could adversely affect our business.
- A failure by us to hire and retain an appropriately skilled and adequate workforce could adversely impact the ability to operate our R&D facility efficiently.
- Use of our laboratory space in San Diego is critical to our success. A natural disaster or other disruptions at our laboratory would adversely affect our business, financial condition, and results of operations.
- We may be unable to manage our future growth effectively, which could make it difficult to execute our business strategy.
- If we acquire companies, products or technologies, we may face integration risks and costs associated with those acquisitions that could negatively impact our business, results from operations and financial condition.
- Our business and operations would suffer in the event of computer system failures.
- We rely extensively on our information technology systems and are vulnerable to damage and interruption, including cybersecurity and data leakage risks.
- Any failure to maintain the security of information relating to our patients, customers, employees and suppliers, whether as a result of cybersecurity attacks or otherwise, could expose us to litigation, government enforcement actions and costly response measures, and could disrupt our operations and harm our reputation.
- Failure to comply with health care privacy and data protection laws and regulations could lead to government enforcement actions (which could include civil or criminal penalties), private litigation, and/or adverse publicity and could negatively affect our operating results and business.
- The use of AI and ML technologies in our business operations and product offerings may expose us to risks that could harm our competitive position and have a material adverse effect on our business and results of operations.
- Changes in general economic conditions, geopolitical conditions, domestic and foreign trade policies, monetary policies and other factors beyond our control may adversely impact our business and operating results.
- Global climate change and related regulations could negatively affect our business.
- Our stockholders will experience substantial dilution from the issuance of shares of common stock upon the exercise of the warrants issued in our August 2025 underwritten public offering. Raising additional capital may also cause dilution to our existing stockholders, restrict our operations or require us to relinquish rights to our technologies or product candidates. Further, our stockholders will experience substantial dilution from the issuance of certain development milestone payments if paid in equity.
- Our failure to meet the listing requirements of Nasdaq could result in a delisting of our common stock. Our ability to publicly or privately sell equity securities and the liquidity of our common stock could be adversely affected if our common stock is delisted.
- Provisions in our certificate of incorporation, bylaws and under Delaware law could discourage a takeover that stockholders may consider favorable.
- Our Second Amended and Restated Bylaws provides that the Court of Chancery of the State of Delaware is the exclusive forum for certain 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.
- The issuance of preferred stock could adversely affect the rights of the holders of shares of our common stock.
- We do not intend to pay dividends in the foreseeable future.
- Holders of our warrants issued in our offerings have no rights as common stockholders until they exercise their warrants and acquire our common stock.
- The market price of our common stock has been and may continue to be volatile and adversely affected by various factors.
- Reports published by securities or industry analysts, including projections in those reports that exceed our actual results, could adversely affect our common stock price and trading volume.
- We are a “smaller reporting company”, and the reduced disclosure requirements applicable to smaller reporting companies may make our common stock less attractive to investors.
Legal proceedings
Lawsuits
We are not currently subject to any material legal proceedings. From time to time, we may be subject to various legal proceedings and claims that arise in the ordinary course of its business activities. Litigation, regardless of the outcome, could have an adverse impact on us because of defense and settlement costs, diversion of management resources and other factors.
