Risk factors and legal proceedings
The risks Ardelyx (United States) names in Item 1A of its 10-K filed Feb 19, 2026: 53 risks under these headings, as written.5
- Risks Related to our Financial Condition and Capital Requirements
- We have incurred losses in each year since our inception, and if we are unable to continue to increase revenue and/or, depending upon our pursuit of future business opportunities, we may not achieve expected cash flow positivity, and even if we do, we may not be able to sustain cash flow positivity quarter over quarter and year over year.
- Our ability to utilize our net operating loss carryforwards and certain other tax attributes may be limited.
- We may require additional financing for the foreseeable future as we invest in the growth of IBSRELA and XPHOZAH in the U.S. and build a pipeline. The inability to access necessary capital when needed on acceptable terms, or at all, could force us to delay or limit our pursuit of other future business opportunities.
- Principal Risks Related to Our Business
- We are substantially dependent on the successful commercialization of IBSRELA, and there is no guarantee that we will maintain sufficient market acceptance for IBSRELA, grow market share for IBSRELA, secure and maintain adequate coverage and reimbursement for IBSRELA, or generate sufficient revenue from product sales of IBSRELA.
- There is no guarantee that we will achieve sufficient market acceptance for XPHOZAH, or that we will be able to secure and maintain adequate coverage and reimbursement for XPHOZAH, or generate sufficient revenue from product sales of XPHOZAH. The inclusion of XPHOZAH in the ESRD PPS creates additional uncertainty as to the commercial opportunity for XPHOZAH.
- XPHOZAH became part of the ESRD PPS on January 1, 2025, which means coverage for XPHOZAH for Medicare beneficiaries is no longer available under Medicare Part D; this resulted in a negative and material impact on our XPHOZAH revenue in 2025; and the continued lack of Medicare Part D coverage for XPHOZAH will result in a materially lower pace of revenue growth as compared to expectations before XPHOZAH became part of the ESRD PPS.
- IBSRELA and/or XPHOZAH may cause undesirable side effects or have other properties that could limit the commercial success of the products.
- Third-party payor coverage and reimbursement status of newly commercialized products are uncertain. Failure to obtain or maintain adequate coverage and reimbursement for IBSRELA and XPHOZAH could limit our ability to market those products and decrease our ability to generate revenue.
- We rely completely on third parties, including certain single-source suppliers, to manufacture IBSRELA and XPHOZAH. If they are unable to comply with applicable regulatory requirements, unable to source sufficient raw materials, experience manufacturing or distribution difficulties or are otherwise unable to manufacture sufficient quantities to meet demand, our commercialization of IBSRELA and XPHOZAH may be materially harmed.
- Our future business prospects may depend on our ability, alone or through our current or future collaborations, to successfully develop, gain regulatory approval of and commercialize our current and future product candidates.
The other 43 risks
- Our future results depend on CMOs, many of whom are our single source manufacturers.
- Our operating activities may be restricted as a result of covenants related to the indebtedness under our loan and security agreement with SLR, as amended, and we may be required to repay the outstanding indebtedness in an event of default, which could have a materially adverse effect on our business.
- Additional Risks Related to Our Business and Industry
- We face substantial competition, and our competitors may discover, develop or commercialize products faster or more successfully than us.
- We may experience difficulties in managing our current activities and growth given our level of managerial, operational, financial and other resources.
- We may engage in strategic transactions that could impact our liquidity, increase our expenses and present significant distractions to our management.
- If product liability lawsuits are brought against us, we may incur substantial liabilities and may be required to limit commercialization of IBSRELA and/or XPHOZAH.
- If we fail to attract, retain and motivate our executives, senior management and key personnel, our business will suffer.
- Actual or perceived failures to comply with applicable data protection, privacy and security laws, regulations, standards and other requirements could adversely affect our business, results of operations, and financial condition.
- We and our collaborators, CROs and other contractors and consultants depend on information technology systems, and any failure of these systems could harm our business. Security breaches, loss of data, and other disruptions could compromise sensitive information related to our business or prevent us from accessing critical information and expose us to liability, which could adversely affect our business, results of operations and financial condition.
- If we fail to maintain proper and effective internal controls, our ability to produce accurate and timely financial statements could be impaired, which could harm our operating results, our ability to operate our business and investors’ views of us and could have a material adverse effect on the price of our common stock.
- We have formed in the past, and may form in the future, collaboration partnerships, joint ventures and/or licensing arrangements, and we may not realize the benefits of such collaborations.
- We will rely on third parties to conduct all of our nonclinical studies and clinical trials. If these third parties do not successfully carry out their contractual duties or meet expected deadlines, we may be unable to obtain regulatory approval for additional products or commercialize our product candidates.
- Our CMOs manufacture tenapanor API outside of the U.S. Our collaboration partners outside of the U.S. have sought and obtained and may continue to seek and obtain approval to commercialize tenapanor outside of the U.S., and as a result, a variety of risks associated with international operations could materially adversely affect our business.
- Changes in U.S. and international trade policies may adversely impact our business and operating results.
- Our business involves the use of hazardous materials and we and third parties with whom we contract must comply with environmental laws and regulations, which can be expensive and restrict how we do business.
- We or the third parties upon whom we depend may be adversely affected by natural disasters, severe weather, public health emergencies and other catastrophic events, and our business continuity and disaster recovery plans may not adequately protect us from a serious disaster.
- Risks Related to Government Regulation
- Current and future healthcare reform legislation, regulation or action by the current administration may increase the difficulty and cost for us to commercialize our approved products and may adversely affect the prices we, or they, may obtain and may have a negative impact on our business and results of operations.
- Despite having received regulatory approval for IBSRELA and XPHOZAH, we will be subject to ongoing regulatory obligations and continued regulatory review, which may result in significant additional expense. Additionally, IBSRELA and XPHOZAH could be subject to other restrictions and market withdrawal, and we may be subject to penalties if we fail to comply with regulatory requirements or experience unanticipated problems with our products.
- Disruptions at the FDA and other government agencies caused by funding shortages or global health concerns could hinder their ability to hire and retain key leadership and other personnel, or otherwise review and process regulatory submissions in a timely manner, which could negatively impact our business.
- We and our CMOs are subject to significant regulation with respect to manufacturing IBSRELA and XPHOZAH. The manufacturing facilities on which we rely may not continue to meet regulatory requirements or may not be able to meet supply demands.
- If we fail to comply or are found to have failed to comply with FDA and other regulations related to the promotion of our products for unapproved uses, other sales practices, as well as the design and implementation of our patient assistance programs, we could be subject to criminal penalties, substantial fines or other sanctions and damage awards.
- IBSRELA and/or XPHOZAH may cause or contribute to adverse medical events that we are required to report to regulatory agencies and if we fail to do so we could be subject to sanctions that would materially harm our business.
- Our employees, independent contractors, principal investigators, CROs, collaboration partners, consultants, CMOs and vendors may engage in misconduct or other improper activities, including noncompliance with regulatory standards and requirements.
- Failure to obtain regulatory approvals in foreign jurisdictions would prevent us from marketing our products internationally.
- We and our collaboration partners are subject to healthcare laws, regulation and enforcement; our failure or the failure of any such collaboration partners to comply with these laws could have a material adverse effect on our results of operations and financial conditions.
- Legislative or regulatory healthcare reforms in the U.S. may make it more difficult and costly for us to obtain regulatory clearance or approval of our product candidates and to produce, market and distribute our products after clearance or approval is obtained.
- If we fail to comply with our reporting and payment obligations under the MDRP or other governmental pricing programs in the U.S., we could be subject to additional reimbursement requirements, penalties, sanctions and fines, which could have a material adverse effect on our business, results of operations and financial condition.
- Risks Related to Intellectual Property
- Our success will depend on our ability to obtain, maintain and protect our intellectual property rights.
- We may become subject to third-party claims alleging infringement, misappropriation or violation of such third parties’ patents or other intellectual property rights and/or third-party claims seeking to invalidate our patents, which would be costly, time consuming and, if successfully asserted against us, delay or prevent the development, manufacture or commercialization of our products or product candidates.
- If we are not able to successfully enforce our intellectual property rights, the commercial value of IBSRELA and XPHOZAH or other product candidates may be adversely affected and we may not be able to compete effectively in our market.
- Although we have obtained patent term extension in the U.S. under the Hatch-Waxman Act, extending the term of exclusivity for tenapanor, if we do not obtain patent term extension in foreign countries under similar legislation, our business may be materially harmed. Furthermore, we have obtained patent term adjustment in the U.S. under the American Inventors Protection Act extending the patent term for certain patents covering tenapanor.
- We may not be able to enforce our intellectual property rights throughout the world.
- If we are unable to protect the confidentiality of our trade secrets, the value of our technology could be materially adversely affected and our business would be harmed.
- If our trademarks and trade names are not adequately protected, then we may not be able to build name recognition in our markets of interest and our business may be adversely affected.
- We may be subject to claims that we or our employees have misappropriated the intellectual property, including know-how or trade secrets, of a third party, or claiming ownership of what we regard as our own intellectual property.
- Risks Related to Our Common Stock
- Our stock price may continue to be volatile and our stockholders may not be able to resell shares of our common stock at or above the price they paid.
- If we sell shares of our common stock in future financings, stockholders may experience immediate dilution and, as a result, our stock price may decline.
- General Risk Factors
- We incur significant costs as a result of operating as a public company, and our management devotes substantial time to new compliance initiatives. We may fail to comply with the rules that apply to public companies, including Section 404 of the Sarbanes-Oxley Act of 2002, which could result in sanctions or other penalties that would harm our business.
- We may be adversely affected by the global economic environment.
- Provisions in our charter documents and under Delaware law could discourage a takeover that stockholders may consider favorable and may lead to entrenchment of management.
- Claims for indemnification by our directors and officers may reduce our available funds to satisfy successful third-party claims against us and may reduce the amount of money available to us.
- We do not currently intend to pay dividends on our common stock, and, consequently, our stockholders’ ability to achieve a return on their investment will depend on appreciation in the price of our common stock.
