Risk factors and legal proceedings
The risks TENAX THERAPEUTICS, INC. names in Item 1A of its 10-K filed Mar 10, 2026: 34 risks under these headings, as written.12
- Risks Related to Our Business and Our Operations
- We are limited in the number of products we can simultaneously pursue and therefore our survival depends on our success with a small number of product opportunities.
- We currently have no approved drug products for sale, and we cannot guarantee that we will ever have marketable drug products.
- Delays in the enrollment and completion of clinical testing could result in increased costs to us and delay or limit our ability to obtain regulatory approval for our product candidates.
- We are conducting two Phase 3 clinical trials, LEVEL and LEVEL-2 for oral levosimendan, which are expensive and time consuming, and the outcome of the clinical trials is uncertain.
- The market may not accept our products.
- Nonfinal results from our clinical trials announced or published from time to time on an interim, top-line, or preliminary basis, and conclusions that may be drawn from such results, may change as more patient data become available, and these results are subject to audit and verification procedures that could result in material changes in the final data.
- Any collaboration we enter with third parties to develop and commercialize any future product candidates may place the development of our product candidates outside our control, may require us to relinquish important rights or may otherwise be on terms unfavorable to us.
- Risks Related to Our Financial Position and Need for Additional Capital
- We may be required to make milestone and royalty payments to the licensor of the levosimendan intellectual property in connection with the development and commercialization of levosimendan, which could adversely affect the profitability of levosimendan, if approved.
- We expect a number of factors to cause our operating results to fluctuate on a quarterly and annual basis, which may make it difficult to predict our future performance.
- We have incurred losses since our inception, expect to continue to incur losses in the foreseeable future, and may never become profitable.
The other 24 risks
- Risks Relating to Our Industry
- Intense competition might render our cardiovascular and pulmonary product candidates noncompetitive or obsolete.
- Our activities are and will continue to be subject to extensive government regulation, which is difficult to predict, expensive and time-consuming, and we will not be able to sell our products without regulatory approval.
- Product approval stage
- Post-commercialization stage
- We may not receive all of the anticipated market exclusivity benefits of imatinib’s orphan drug designation, if we prioritize imatinib development in the future.
- Even after products are commercialized, we would expect to spend considerable time and money complying with federal, state, and foreign laws and regulations governing their sale, and, if we are unable to fully comply with such laws and regulations, we could face substantial penalties.
- We are subject to uncertainty relating to healthcare reform measures and reimbursement policies that, if not favorable to our products, could hinder or prevent our products’ commercial success, if any of our product candidates are approved.
- Governments outside the United States tend to impose strict price controls and reimbursement approval policies, which may adversely affect our prospects for generating revenue outside the United States.
- Product liability lawsuits against us could cause us to incur substantial liabilities, limit sales of our existing products and limit commercialization of any products that we may develop.
- Our business and operations would suffer in the event of computer system failures, cyber-attacks or deficiencies in our cybersecurity.
- Risks Related to Our Dependence on Third Parties
- We have historically relied on and we will continue to substantially rely on third parties to conduct our nonclinical testing and clinical studies and other aspects of our development programs. If those third parties do not satisfactorily perform their contractual obligations or meet anticipated deadlines, the development of our product candidates could be adversely affected.
- We depend on third parties to formulate and manufacture our products.
- If we fail to attract and retain senior management and key scientific personnel, we may be unable to successfully develop and commercialize our product candidates.
- We expect to need to increase the size of our organization to further develop our product candidates, and we may experience difficulties in managing growth.
- We currently have very limited marketing capabilities and no sales organization. If we are unable to establish sales and marketing capabilities on our own or through third parties, we will be unable to successfully commercialize our products, if approved, or generate product revenue.
- Risks Related to Intellectual Property
- Our success will depend in part on obtaining and maintaining effective patent and other intellectual property protection for our product candidates and proprietary technology.
- We rely on confidentiality agreements that, if breached, may be difficult to enforce and could have a material adverse effect on our business and competitive position.
- 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, or use, our technology.
- Under current law, we may not be able to enforce all employees’ covenants not to compete and therefore may be unable to prevent our competitors from benefiting from the expertise of some of our former employees.
- We may infringe or be alleged to infringe intellectual property rights of third parties.
- Risks Related to Owning Our Common Stock
- Our share price has been volatile, and may continue to be volatile, which may subject us to securities class action litigation in the future.
- Investors may experience dilution of their ownership interests because of the future issuance of additional shares of our common stock or securities convertible into common stock.
- Anti-takeover provisions in our corporate charter documents and under Delaware law could make an acquisition of us more difficult, which could discourage takeover attempts and lead to management entrenchment, and the market price of our common stock may be lower as a result.
- Our Bylaws contain an exclusive forum provision, which could limit our stockholders’ ability to obtain a favorable judicial forum for disputes with us or our directors, officers, employees, or agents.
- We have not paid cash dividends in the past and do not expect to pay dividends in the future. Any return on investment may be limited to the value of our common stock.
- Our ability to use our net operating loss carryforwards and certain other tax attributes to offset future taxable income may be subject to certain limitations.
Legal proceedings
We are subject to litigation in the normal course of business, none of which management believes will have a material adverse effect on our consolidated financial statements.
