Risk factors and legal proceedings
The risks ENANTA PHARMACEUTICALS INC names in Item 1A of its 10-K filed Nov 19, 2025: 50 risks under these headings, as written.6
- Risks Related to Our Business
- We will require substantial additional funding to achieve our goals. A failure to obtain this funding when needed could force us to delay, limit, reduce or terminate some or all of our product development efforts.
- Our revenues are dependent upon royalty revenues derived from AbbVie’s net sales of its MAVYRET/MAVIRET regimen for HCV, which includes our protease inhibitor, glecaprevir. If AbbVie is unable to maintain sales of this regimen at or
- above current levels of sales, our royalty revenues, as well as our retained cash portion of royalties, will be adversely affected.
- We and AbbVie face substantial competition in the markets for HCV drugs, and there are many companies developing potential therapies for RSV and other viral infections, as well as for CSU, AD and other immunology diseases, which may result in others discovering, developing or commercializing products before we do or doing so more successfully than we do.
- RSV, CSU and AD, as well as COVID-19 and HBV, represent competitive therapeutic areas.
- We have not developed independently any approved products and we have limited clinical development experience, which makes it difficult to assess our ability to develop and commercialize our product candidates.
- If we are not successful in discovering and developing KIT and STAT6 inhibitors, or in obtaining one or more partners to advance zelicapavir, EDP-323, EDP-235 or EDP-514, or in discovering further product candidates, our ability to expand our business and achieve our strategic objectives will be impaired.
- If we fail to attract and keep senior management and key scientific personnel, we may be unable to successfully develop our product candidates, conduct our clinical trials and commercialize our product candidates.
- We may encounter difficulties expanding our operations successfully to advance our product candidates.
- Risks Related to Development, Clinical Testing and Regulatory Approval of Our Product Candidates
- Clinical drug development involves a lengthy and expensive process with uncertain timelines and uncertain outcomes. Any ongoing or future clinical trials of our product candidates may fail to demonstrate sufficient safety and efficacy. If clinical trials of any of our proprietary product candidates are prolonged or delayed or fail, we may be unable to commercialize our product candidates on a timely basis or ever.
The other 39 risks
- Zelicapavir or EDP-323, or any other product candidate emerging from our current research programs, may have undesirable side effects which may delay or prevent marketing approval or, if approval is received, require our product candidate to be taken off the market, require us to include safety warnings or otherwise limit sales.
- If we are required to suspend or discontinue clinical trials due to side effects or other safety risks associated with our product candidates, or if we are required to conduct studies on the long-term effects associated with the use of any of those product candidates, then commercialization any of those product candidates could be delayed or halted.
- Results of earlier clinical trials may not be predictive of the results of later-stage clinical trials.
- The regulatory approval processes of the FDA, the EMA and other comparable foreign authorities are lengthy, time-consuming and inherently unpredictable, and if we are ultimately unable to obtain timely regulatory approval for our product candidates, our business will be substantially harmed.
- The regulatory pathway for approval of a therapeutic treatment for COVID-19 such as EDP-235 is continually evolving and may result in unexpected or unforeseen challenges and longer timelines than seen for earlier COVID-19 vaccines and therapeutics.
- Even if we receive regulatory approval for any of our product candidates we develop independently, we will be subject to ongoing FDA obligations and continued regulatory review in other jurisdictions, which may result in significant additional expense. Additionally, our product candidates, if approved, could be subject to labeling and other restrictions and market withdrawal and we may be subject to penalties if we or our collaborators fail to comply with regulatory requirements or experience unanticipated problems with our products.
- We may delay or terminate the development of a product candidate at any time if we believe the perceived market or commercial opportunity does not justify further investment, which could materially harm our business and adversely affect our stock price.
- Risks Related to Commercialization of Our Product Candidates
- Unfavorable pricing regulations, third-party reimbursement practices or healthcare reform initiatives in the United States could harm our business.
- Foreign governments tend to impose strict price controls, which may adversely affect our future profitability.
- If, in the future, we are unable to establish our own sales, marketing and distribution capabilities or enter into licensing or collaboration agreements for these purposes, we may not be successful in commercializing any product candidates.
- Commercial success of our product candidates depends upon significant market acceptance among physicians, patients and healthcare payors of any resulting approved drug.
- Risks Related to Our Dependence on Third Parties
- We may not be successful in establishing new product collaborations, which could adversely affect our ability to develop and commercialize one or more of our product candidates. If we are unsuccessful in maintaining or forming alliances on favorable terms, our business may not succeed.
- We intend to rely on third-party manufacturers to produce our development-stage product candidate supplies and any commercial supplies of any approved product candidates. Any failure by a third-party manufacturer to produce acceptable supplies for us may delay or impair our ability to initiate or complete our clinical trials or sell any resulting product.
- To the extent we elect to enter into additional licensing or collaboration agreements to partner our product candidates, our dependence on such relationships may adversely affect our business.
- Risks Related to Our Intellectual Property Rights
- We are competing to develop intellectual property in areas of small-molecule drug development that are highly competitive. We could be unsuccessful in obtaining or maintaining adequate patent protection for one or more of our product candidates.
- Claims that our product candidates or the sale or use of our products infringe the patent or other intellectual property rights of third parties could result in costly litigation or could require substantial time and money to resolve, even if litigation is avoided.
- Issued patents covering one or more of our product candidates could be found invalid or unenforceable if challenged in court, including as a result of counterclaims filed against us in connection with our efforts to enforce our intellectual property rights against third parties.
- Intellectual property litigation may lead to unfavorable publicity that harms our reputation and causes the market price of our common stock to decline.
- Intellectual property rights do not necessarily protect us from all potential threats to our competitive advantage.
- Unfavorable outcomes in intellectual property litigation could limit our research and development activities and/or our ability to commercialize certain products.
- Confidentiality agreements with employees and third parties may not prevent unauthorized disclosure of trade secrets and other proprietary information.
- Changes in patent law could diminish the value of patents in general, thereby impairing our ability to protect our products.
- Risks Related to Our Industry
- If product liability lawsuits are brought against us, we may incur substantial liabilities and may be required to limit commercialization of our product candidates.
- Our internal computer systems, or those of our collaborator, CROs or other contractors or consultants, may fail or suffer security breaches, which could result in a material disruption of development programs for our product candidates.
- Our relationships with customers and third-party payors in the United States and elsewhere will be subject to applicable anti-kickback, fraud and abuse and other healthcare laws and regulations, which could expose us to criminal sanctions, civil penalties, contractual damages, reputational harm and diminished profits and future earnings.
- Risks Related to Our Common Stock
- Our stock price has been, and is likely to continue to be, volatile, and thus our stockholders could incur substantial losses.
- A sale of a substantial number of shares of our common stock in the public market could cause the market price of our common stock to drop significantly, even if our business is doing well.
- If securities or industry analysts do not publish research, or publish inaccurate or unfavorable research about our business, our stock price and trading volume would likely decline.
- 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 employment agreements with our executive officers may require us to pay severance benefits to any of those persons who are terminated in connection with a change of control of us, which could harm our financial condition or results.
- Because we do not anticipate paying cash dividends on our common stock for the foreseeable future, investors in our common stock may never receive a return on their investment.
- Our ability to use future net operating loss carryforwards, research and development tax credit carryforwards, and certain other tax attributes may be limited.
- We are a smaller reporting company, and any decision on our part to comply only with reduced reporting and disclosure requirements applicable to such companies could make our common stock less attractive to investors.
- General Risk Factors
- If we fail to comply with environmental, health and safety laws and regulations, we could become subject to fines or penalties or incur costs that could have a material adverse effect on the success of our business.
- Our insurance policies are expensive and only protect us from specified business risks, which will leave us exposed to significant uninsured liabilities.
- 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 information technology systems, or those used by our CROs or other contractors or consultants, may fail or suffer other breakdowns, cyber-attacks, or information security breaches, which could adversely affect our business.
- Use of social media could give rise to liability or reputational harm.
- We maintain our cash at financial institutions, often in balances that exceed federally insured limits.
