Risk factors and legal proceedings
The risks Plus Therapeutics names in Item 1A of its 10-K filed Mar 12, 2026: 63 risks under these headings, as written.6
- Risks Related to our Financial Position and Capital Requirements
- We have incurred losses since inception, we expect to incur significant net losses in the foreseeable future and we may never become profitable and our operating results have been and will likely continue to be volatile.
- Uncertainties relating to our ability to fund our operations raises substantial doubt about our ability to continue as a going concern.
- We could be delisted from Nasdaq for failure to comply with the Minimum Stockholders’ Equity Requirement, the Minimum Bid Requirement or other applicable continued listing requirements and standards of Nasdaq, which would seriously harm the liquidity of our stock and our ability to raise capital.
- Potential Consequences of Delisting
- We will need substantial additional funding to develop our product candidates and conduct our future operations and to repay our outstanding debt obligations. If we are unable to obtain the funds necessary to do so, we may be required to delay, scale back or eliminate our product development activities or may be unable to continue our business operations.
- We maintain our cash at financial institutions, often in balances that exceed federally insured limits.
- Our ability to utilize our net operating loss carryforwards and certain other tax attributes may be limited.
- Risks Related to Our Business and Industry
- If we fail to maintain proper and effective internal controls, our ability to produce accurate financial statements on a timely basis could be impaired.
- Our future success is in large part dependent upon our ability to successfully develop our nanomedicine platform and commercialize rhenium (186Re) obisbemeda and 188RNL-BAM and any failure to do so could significantly harm our business and prospects.
- 188RNL-BAM will be regulated as a medical device, which may result in additional regulatory and other risks.
The other 54 risks
- We recently acquired the CNSide Portfolio, and we may not be successful in our efforts to develop, fully utilize and monetize it.
- If we are unable to successfully partner with other companies to commercialize our product candidates, our business could materially suffer.
- Our success depends in substantial part on our ability to obtain regulatory clearance, authorization or approval for our RNL product candidates. However, we cannot be certain that we will receive regulatory clearance, authorization or approval for these product candidates or our other product candidates.
- If we or any party to a key collaboration, licensing, development, acquisition or similar arrangement fail to perform material obligations, or commit a breach, under such arrangement, or any arrangement is terminated for any reason, there could be an adverse effect on our business.
- Our current business strategy is high-risk and may not be successful.
- Reliance on government funding for our programs may impose requirements that limit our ability to take certain actions, and subject it to potential financial penalties, which could materially and adversely affect our business, financial condition and results of operations.
- The DoD Award is dependent on continued U.S. government funding and government appropriations, which may not be forthcoming on a timely basis or at all.
- If our competitors market or develop products that are marketed more effectively, approved more quickly than our product candidates, or demonstrated to be safer or more effective than our product candidates, our commercial opportunities could be reduced or eliminated.
- Product development involves a lengthy and expensive process, with an uncertain outcome. We may incur additional costs or experience delays in completing, or ultimately be unable to complete, the development and commercialization of our product candidates.
- Preclinical studies and preliminary and interim data from clinical trials of our product candidates are not necessarily predictive of the results or success of ongoing or future clinical trials of our product candidates.
- Because we have limited resources, we may decide to pursue a particular product candidate and fail to advance product candidates that later demonstrate a greater chance of clinical and commercial success.
- Clinical trial results may fail to support approval of our product candidates.
- If third parties we engage are not able to successfully perform, we may not be able to successfully complete clinical development, obtain regulatory approval or commercialize our product candidates and our business could be substantially harmed.
- We may have difficulty enrolling, or fail to enroll patients, in our clinical trials, which could delay or prevent clinical trials of our drug candidates.
- If a particular product candidate causes significant adverse events, then we may be unable to receive regulatory approval or market acceptance for such product candidate.
- If our product candidates and technologies receive regulatory approval but do not achieve broad market acceptance, especially by physicians, the revenue that we generate will be limited.
- All potential applications of our product candidates are investigational, which subjects us to development and marketing risks.
- We and our product candidates are subject to extensive regulation, and the requirements to obtain regulatory approvals in the United States and other jurisdictions can be costly, time-consuming and unpredictable. If we or our partners are unable to obtain timely regulatory approval for our product candidates, our business may be substantially harmed.
- We will be subject to ongoing regulatory obligations and continued regulatory review, which may result in significant expense, and if we or our collaborators fail to comply with such requirements, regulatory agencies may take action against us or them, which could significantly harm our business.
- The future regulatory processes that will be applicable to LDTs are uncertain and may prevent us from obtaining required authorizations for the commercialization of our products and/or introduce additional costs associated with those products.
- Changing, new and/or emerging government regulations, including healthcare legislative reform measures, may adversely affect us.
- Healthcare reform measures could hinder or prevent the commercial success of our LDTs or any product candidate for which we obtain regulatory approval.
- Adequate coverage and reimbursement from third party payors may not be available for our product candidates, which could diminish our sales or adversely affect our ability to sell our products profitably.
- Some intellectual property that we have in-licensed has been discovered through government funded programs and thus may be subject to federal regulations such as “march-in” rights, certain reporting requirements and a preference for U.S.-based companies. Compliance with such regulations may limit our exclusive rights and limit our ability to contract with non-U.S. manufacturers.
- Orphan drug designation may not ensure that we will enjoy market exclusivity in a particular market, and if we fail to obtain or maintain orphan drug designation or other regulatory exclusivity for some of our product candidates, our competitive position would be harmed.
- Fast Track Designation by the FDA may not lead to a faster development or regulatory review or approval process.
- A Rare Pediatric Disease designation by the FDA does not guarantee that the NDA for the product will qualify for a priority review voucher upon approval, and it does not lead to a faster development or regulatory review process, or increase the likelihood that rhenium (186Re) obisbemeda or our future product candidates will receive marketing approval.
- If we decide to pursue accelerated approval for any of our product candidates, it may not lead to a faster development or regulatory review or approval process and does not increase the likelihood that our product candidates will receive marketing approval.
- If we experience an interruption in supply from a material sole source supplier, our business may be harmed.
- We may engage in strategic transactions that could impact our liquidity, increase our expenses, and present significant distractions to our management.
- We must maintain quality controls and compliance with manufacturing standards.
- If we are unable to identify, hire and/or retain key personnel, we may not be able to sustain or grow our business.
- We face potential product liability exposure, and if successful claims are brought against us, we may incur substantial liability if our insurance coverage for those claims is inadequate.
- A failure to adequately protect health information could result in severe harm to our reputation and subject us to significant liabilities, each of which could have a material adverse effect on our business.
- We and our collaborators must comply with environmental laws and regulations, including those pertaining to use of hazardous and biological materials in our business, and failure to comply with these laws and regulations could expose us to significant liabilities.
- We may not be successful in our efforts to develop, fully utilize and monetize the CNSide diagnostic portfolio.
- Clinical laboratories are highly regulated and if we are unable to maintain compliance with these regulations, or if the regulations change in ways that make it more difficult or costly to comply, our financial condition and our business may be harmed.
- Our relationships with customers, healthcare providers, including physicians, and third-party payors are subject, directly or indirectly, to federal and state healthcare fraud and abuse laws, false claims 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.
- The diagnostic testing industry is subject to rapid change, which could make our current or future products obsolete.
- Risks Relating to Our Intellectual Property
- Our success depends in part on our ability to protect our intellectual property.
- If we do not obtain patent term extension for any product candidates we may develop, our business may be materially harmed.
- We may not be able to protect our trade secrets.
- We may be subject to claims that our employees have wrongfully used or disclosed alleged trade secrets of their former employers.
- We may incur substantial costs as a result of litigation or other proceedings relating to patent and other intellectual property rights, and we may be unable to protect our rights to our product candidates and technology.
- If we are sued for infringing intellectual property rights of third parties, it will be costly and time consuming, and an unfavorable outcome in that litigation would have a material adverse effect on our business.
- Risks Relating to the Issuance of Capital Stock, the Securities Markets and an Investment in Our Common Stock
- Our stockholders may experience substantial dilution in the value of their investment if we issue additional shares of our capital stock.
- The market price of our common stock may be volatile and fluctuate significantly, which could result in substantial losses for stockholders.
- We may be or become the target of securities litigation, which is costly and time-consuming to defend.
- We may issue debt and equity securities or securities convertible into equity securities, any of which may be senior to our common stock as to distributions and in liquidation, which could negatively affect the value of our common stock.
- Our charter documents contain anti-takeover provisions.
- We presently do not intend to pay cash dividends on our common stock.
- If securities and/or industry analysts fail to continue publishing research about our business, if they change their recommendations adversely, or if our results of operations do not meet their expectations, our stock price and trading volume could decline.
- General Risk Factors
- Increased information technology security threats and more sophisticated and targeted computer crime could pose a risk to our systems, networks, and products.
