Risk factors and legal proceedings
The risks Bicycle Therapeutics (United Kingdom) names in Item 1A of its 10-K filed Mar 17, 2026: 73 risks under these headings, as written.7
- Risks Related to Our Financial Position and Need for Additional Capital
- We have a history of significant operating losses and expect to incur significant and increasing losses for the foreseeable future, and we may never achieve or maintain profitability.
- Our limited operating history may make it difficult for holders of our ADSs or ordinary shares to evaluate the success of our business to date and to assess our future viability.
- We may need substantial additional funding, and if we are unable to raise capital when needed, we could be forced to delay, reduce or eliminate our product discovery and development programs or commercialization efforts.
- Raising additional capital may cause dilution to our existing shareholders or holders of our ADSs, restrict our operations or cause us to relinquish valuable rights.
- Risks Related to the Discovery, Development and Regulatory Approval of Our Product Candidates
- We are substantially dependent on the success of our internal development programs and of our product candidates from our BDC and BRC programs, which may not successfully complete clinical trials, receive regulatory approval or be successfully commercialized.
- We are at an early stage in our development efforts, and our product candidates and those of our collaborators represent a new category of medicines and may be subject to heightened regulatory scrutiny until they are established as a therapeutic modality.
- We may find it difficult to enroll patients in our clinical trials, which could delay or prevent us from proceeding with clinical trials of our product candidates.
- Results of preclinical studies and early clinical trials may not be predictive of results of future clinical trials.
- Failure to successfully validate, develop and obtain regulatory approval for companion diagnostics could harm our drug development strategy.
- Our current or future product candidates may cause undesirable side effects or have other properties when used alone or in combination with other approved products or investigational new drugs that could halt their clinical development, prevent their marketing approval, limit their commercial potential or result in significant negative consequences.
The other 62 risks
- We may be delayed or may not be successful in our efforts to identify or discover additional product candidates.
- We may expend our limited resources to pursue a particular development strategy, product candidate or indication and fail to capitalize on strategies, product candidates or indications that may be more profitable or for which there is a greater likelihood of success.
- We face potential product liability, and, if successful claims are brought against us, we may incur substantial liability and costs. If the use of our product candidates harms patients, or is perceived to harm patients even when such harm is unrelated to our product candidates, our regulatory approvals could be revoked or otherwise negatively impacted and we could be subject to costly and damaging product liability claims.
- We may seek designations for our product candidates with the FDA and other comparable regulatory authorities that are intended to confer benefits such as a faster development process or an accelerated regulatory pathway, but there can be no assurance that we will successfully obtain such designations. In addition, even if one or more of our product candidates are granted such designations, we may not be able to realize the intended benefits of such designations.
- We may seek priority review designation for one or more of our product candidates, but we might not receive such designation, and even if we do, such designation may not lead to a faster regulatory review or approval process.
- Obtaining and maintaining marketing approval of our current and future product candidates in one jurisdiction does not mean that we will be successful in obtaining marketing approval of our current and future product candidates in other jurisdictions.
- Changes in the regulatory landscape, policies, or processes, as well as disruptions at the FDA and other government agencies caused by layoffs, changes in personnel, funding shortages or global health concerns could negatively impact our business.
- Risks Related to Commercialization of Our Product Candidates and Other Regulatory Compliance Matters
- Even if we complete the necessary preclinical studies and clinical trials, the marketing approval process is expensive, time consuming and uncertain and may prevent us or any collaborators from obtaining approvals for the commercialization of some or all of our product candidates. As a result, we cannot predict when or if, and in which territories, we, or any collaborators, will obtain marketing approval to commercialize a product candidate.
- We currently have limited marketing, sales or distribution infrastructure with respect to our product candidates. If we are unable to develop our sales, marketing and distribution capability on our own or through collaborations with marketing partners, we will not be successful in commercializing our product candidates.
- The market opportunities for any current or future product candidate we develop, if and when approved, may be limited to those patients who are ineligible for established therapies or for whom prior therapies have failed, and may be small.
- Even if we receive marketing approval of a product candidate, we will be subject to ongoing regulatory obligations and continued regulatory review, which may result in significant additional expense and we may be subject to penalties if we fail to comply with regulatory requirements or experience unanticipated problems with our products, if approved.
- We face significant competition and if our competitors develop and market products that are more effective, safer or less expensive than the product candidates we develop, our commercial opportunities will be negatively impacted.
- The commercial success of any current or future product candidate will depend upon the degree of market acceptance by physicians, patients, payors and others in the medical community.
- If the market opportunities for our product candidates are smaller than we believe they are, our product revenues may be adversely affected and our business may suffer.
- The insurance coverage and reimbursement status of newly approved products is uncertain. Failure to obtain or maintain adequate coverage and reimbursement for any of our product candidates, if approved, could limit our ability to market those products and decrease our ability to generate revenue.
- If the FDA or comparable foreign regulatory authorities approve generic versions of any of our product candidates that receive marketing approval, or such authorities do not grant such products appropriate periods of data exclusivity before approving generic versions of such products, the sales of such products could be adversely affected.
- We may be subject, directly or indirectly, to federal and state healthcare fraud and abuse laws, false claims laws, health information privacy and security laws, and other health care laws and regulations. If we are unable to comply, or have not fully complied, with such laws, we could face substantial penalties.
- work) actual or perceived failure to comply with such obligations could lead to regulatory investigations or actions, litigation, fines and penalties, disruptions of our business operations, reputational harm, loss of revenues or profits, and other adverse business consequences.”
- Healthcare legislative reform measures may have a negative impact on our business and results of operations.
- We are subject to the U.K. Bribery Act 2010, or the Bribery Act, the U.S. Foreign Corrupt Practices Act of 1977, as amended, or the FCPA, and other anti-corruption laws, as well as export control laws, import and customs laws, trade and economic sanctions laws and other laws governing our operations.
- We and the third parties with whom we work are subject to stringent and evolving U.S. and foreign laws, regulations, rules, contractual obligations, industry standards, policies and other obligations related to data privacy and security. Our (and third parties with whom we work) actual or perceived failure to comply with such obligations could lead to regulatory investigations or actions, litigation (including class claims), fines and penalties, disruptions of our business operations, reputational harm, loss of revenue or profits, and other adverse business consequences.
- Our activities subject us to various laws relating to foreign investment and the export of certain technologies, and our failure to comply with these laws or adequately monitor the compliance of our suppliers and others we do business with could subject us to substantial fines, penalties and even injunctions, the imposition of which on us could have a material adverse effect on the success of our business.
- 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.
- Risks Related to Our Business and Our International Operations
- As a company with operations outside of the United States, we are subject to economic, political, regulatory and other risks associated with international operations.
- International trade policies, including tariffs, sanctions and trade barriers may adversely affect our business, financial condition, results of operations and prospects.
- Cyber-attacks, failures in or interruptions of, or other compromise to our information technology systems, or those of third parties with whom we work, or our data could result in adverse consequences that materially affect our business, including without limitation, regulatory investigations or actions, litigation, fines and penalties, information theft, data corruption, harm to our reputation and brand, significant disruption of our business operations, and other adverse consequences.
- Social media platforms and artificial intelligence-based platforms present new risks and challenges to our business.
- Exchange rate fluctuations may materially affect our results of operations and financial condition.
- Risks Related to Our Dependence on Third Parties
- For certain product candidates, we depend, or may depend, on development and commercialization collaboration partners to develop, conduct clinical trials, obtain regulatory approvals of, and if approved, market and sell product candidates. If such partnerships fail to perform as expected, the potential for us to generate future revenue from such product candidates would be significantly reduced and our business would be harmed.
- If conflicts arise with our development and commercialization collaborators or licensors, they may act in their own self-interest, which may be adverse to the interests of our company.
- We rely on third parties, including independent clinical investigators and CROs, to conduct and sponsor some of the clinical trials of our product candidates. Any failure by a third party to meet its obligations with respect to the clinical development of our product candidates may delay or impair our ability to obtain regulatory approval for our product candidates.
- We intend to rely on third parties to manufacture product candidates and supply raw materials used in our product candidates, such as 212Pb, which increases the risk that we will not have sufficient quantities of such product candidates or products or such quantities at an acceptable cost, which could delay, prevent or impair our development or commercialization efforts.
- Our reliance on third parties requires us to share our trade secrets, which increases the possibility that a competitor will discover them or that our trade secrets will be misappropriated or disclosed.
- Risks Related to Our Intellectual Property
- If we are unable to obtain and maintain patent and other intellectual property protection for our products and product candidates, or if the scope of the patent and other intellectual property protection obtained is not sufficiently broad, our competitors could develop and commercialize products similar or identical to ours, and our ability to successfully commercialize our products and product candidates may be adversely affected.
- Issued patents covering our products and product candidates could be found invalid or unenforceable if challenged in court or in administrative proceedings. We may not be able to protect our trade secrets in court.
- We may be subject to claims challenging the inventorship or ownership of the patents and other intellectual property.
- Obtaining and maintaining patent protection depends on compliance with various procedural, document submission, fee payment and other requirements imposed by governmental patent agencies, and our patent protection could be reduced or eliminated for non-compliance with these requirements.
- If we do not obtain patent term extension and data exclusivity for our products and product candidates, our business may be materially harmed.
- Changes in patent law in the United States and other jurisdictions could diminish the value of patents in general, thereby impairing our ability to protect our products and product candidates.
- We may not be able to protect our intellectual property rights throughout the world.
- If we are sued for infringing intellectual property rights of third parties, such litigation could be costly and time consuming and could prevent or delay us from developing or commercializing our product candidates.
- We may be subject to claims by third parties asserting that our employees or we have misappropriated their intellectual property, or claiming ownership of what we regard as our own intellectual property.
- We may become involved in lawsuits to protect or enforce our patents and other intellectual property rights, which could be expensive, time-consuming and unsuccessful.
- If we fail to comply with our obligations under any future intellectual property licenses with third parties, we could lose license rights that are important to our business.
- If our trademarks and trade names are not adequately protected, then we may not be able to build name recognition in our marks of interest and our business may be adversely affected.
- Risks Related to Employee Matters and Managing Growth
- Our recent workforce reductions were undertaken to significantly reduce our ongoing operating expenses, but they may not result in our intended outcomes and may yield unintended consequences and additional costs.
- Our future success depends on our ability to retain key employees, consultants and advisors and to attract, retain and motivate qualified personnel.
- Our employees, independent contractors, consultants, collaborators and CROs may engage in misconduct or other improper activities, including non-compliance with regulatory standards and requirements, which could cause significant liability for us and harm our reputation.
- We may encounter difficulties in managing our growth, which could disrupt our operations.
- Risks Related to Ownership of Our Securities
- The market price of our ADSs is highly volatile, and holders of our ADSs may not be able to resell their ADSs at or above the price at which they purchased their ADSs.
- The dual class structure of our shares may limit your ability to influence corporate matters and may limit your visibility with respect to certain transactions.
- Substantial future sales or issuances of shares of our ordinary shares or ADSs or other equity-related securities could adversely affect the price of our ADSs and dilute shareholders.
- Our existing shareholders may consult with our management and have various impacts on our business affairs.
- Because we do not anticipate paying any cash dividends on our ADSs in the foreseeable future, capital appreciation, if any, will be the sole source of gains for holders of our ADSs, and they may never receive a return on their investment.
- Risks Related to Our Incorporation Under the Laws of England and Wales
- Claims of U.S. civil liabilities may not be enforceable against us.
- If we are a passive foreign investment company, there could be adverse U.S. federal income tax consequences to U.S. holders.
- We may be unable to use net operating loss and tax credit carryforwards and certain built-in losses to reduce future tax payments or benefit from favorable U.K. tax legislation.
- Future changes to tax laws could materially adversely affect our company and reduce net returns to our shareholders.
- Tax authorities may disagree with our positions and conclusions regarding certain tax positions, or may apply existing rules in an unforeseen manner, resulting in unanticipated costs, taxes or non-realization of expected benefits.
- Provisions in the U.K. City Code on Takeovers and Mergers that may have anti-takeover effects do not apply to us.
- The rights of our shareholders may differ from the rights typically offered to shareholders of a U.S. corporation.
Legal proceedings
From time to time, we may become subject to various legal proceedings and claims that arise in the ordinary course of our business activities. We are not currently subject to any material legal proceedings.
