Refer to the “Item 1A. Risk Factors” section in our Annual Report on Form 10-K for the year ended December 31, 2025 for a discussion of risks to which our business, financial condition, results of operations and cash flows are subject. Other than as described below, there have been no material changes to the risk factors disclosed in the aforementioned Annual Report. Risks Related to the Development, Regulatory Approval and Commercialization of our iLet Bionic Pancreas and Product Candidates We are highly dependent on the success of our iLet for the treatment of T1D, which is cleared by the FDA for commercial sale in the United States for the treatment of T1D, and we do not have any other commercial products. If we are unable to obtain and maintain regulatory clearance or approval for planned modifications to the iLet or for new indications, or for any current or future development-stage products, or if we are unsuccessful in our efforts to continue to commercialize our cleared version of the iLet, our business will be materially harmed. We only have one commercialized device, the iLet, which is an automated insulin dosing system cleared for the treatment of T1D in adults and children six years of age and older. Our business primarily depends on the successful commercialization of the iLet. We currently have no other products cleared for sale and may never be able to develop other marketable products. Our iLet will require additional clinical development, testing and marketing authorization or regulatory clearance before we are permitted to commercialize it in a bihormonal system for the treatment of T1D or for any future indications we may pursue. Further, as we develop a bihormonal system of the iLet, which is designed to use both insulin and glucagon for the treatment of T1D, we will separately need to develop and obtain approval for our glucagon product candidate as a drug via an NDA submission in order to successfully commercialize our iLet in a bihormonal system. We expect that the bihormonal system will require completion of clinical trials and submission of a 510(k) for both the infusion pump and algorithm. In addition, we expect that the single hormone and bihormonal algorithms will require separate studies to be performed in T1D and T2D populations in order to seek clearance in these patient populations. In addition, we are developing Mint, an insulin pump, also commonly referred to as a “patch pump,” for which we have submitted a 510(k) application to the FDA. We currently expect to fully commercialize Mint by the end of the second quarter of 2027, subject to regulatory clearance by the FDA. However, there can be no assurance that the FDA will clear the Mint 510(k) application on the anticipated timeline, or at all, or that we will be able to scale our manufacturing processes sufficiently to meet anticipated demand at launch. The future regulatory and commercial success of our iLet, Mint and any other product candidate is subject to a number of risks, including the following: •completion of preclinical studies with favorable results; •successful enrollment in, and completion of, planned and future clinical trials with favorable results; •sufficiency of our financial and other resources to complete the necessary clinical trials and regulatory activities; •successful patient enrollment in clinical trials; •successful data from our clinical program that supports an acceptable risk-benefit profile in the intended populations; •whether we are required by the FDA to conduct additional clinical trials or to modify the design of current or planned trials to support any future application seeking marketing authorization or clearance of the iLet in a bihormonal system for the treatment of T1D or for other indications we may pursue, or seeking initial marketing authorization or clearance for any of our other product candidates; •receipt and maintenance of marketing authorizations or clearances from applicable regulatory authorities; •obtaining and maintaining patent and trade secret protection and regulatory exclusivity for our iLet; •making arrangements with third-party manufacturers and ensuring such third-party manufacturers supply sufficient quantities of components of our products and product candidates; •scaling up our manufacturing capabilities, for both commercial and clinical supplies of our products and product candidates; 41 •entry into collaborations to further the development of our iLet’s capabilities; •expanding sales, marketing and distribution capabilities as we continue our commercialization efforts of the iLet, whether alone or in collaboration with others; •successfully launching commercial sales of the iLet, patch pump and any other product candidate, if authorized for marketing or cleared; •acceptance of our products by PWD, the medical community and third-party payors; •maintaining a continued acceptable safety profile following marketing authorization or clearance; •maintaining regulatory compliance; •effectively competing with other treatment options and the availability, perceived advantages, relative cost, relative safety and relative effectiveness of alternative and competing treatments; •the emergence of competing technologies and other adverse market developments, and our need to enhance existing products and/or develop new products to maintain market share in response to such competing technologies or market developments; •maintaining healthcare coverage and adequate reimbursement from third-party payors; •continuing to build and maintain an organization of people who can successfully develop our products; and •enforcing and defending intellectual property rights and claims. Many of these risks are beyond our control, including the risks related to clinical development, the regulatory submission process, potential threats to our intellectual property rights and the manufacturing, marketing and sales efforts of any future collaborator. If we are not successful in commercializing our iLet or obtaining marketing authorization or clearance for the iLet in its bihormonal system for the treatment of T1D or in other indications, such as T2D, the investigational glucagon product, Mint, or any other product candidate, or if we experience delays as a result of any of these risks or otherwise, our business could be materially harmed. Furthermore, even though we have received clearance for our iLet for insulin-only delivery for the treatment of T1D, any other configuration for the treatment of T1D such as a bihormonal system using both insulin and glucagon or other indications we may pursue for which we receive marketing authorization or clearance may be subject to limitations on the patient populations for which we may market the product. Even if we are able to obtain the requisite financing to continue to fund our development programs, we cannot assure you that we will successfully develop, obtain marketing authorization or clearance for, and commercialize our iLet in its bihormonal system for the treatment of T1D or for any future indication we may pursue, Mint, the investigational glucagon product, or any other development-stage products. If we are unable to continue commercializing the iLet for T1D, or if we are unable to develop, or obtain marketing authorization or clearance for, or, if authorized for marketing or cleared, successfully commercialize the iLet for the treatment of any future indications, we may not be able to generate sufficient revenue to continue our business. Our future growth depends on the continued success, enhancement, and expanded use of the iLet as well as the development and commercial release of the patch pump, Mint. If we fail to advance the iLet platform, the Mint platform or expand their indications, our business may be adversely affected. It is important to our business and our long-term growth that we continue to develop and enhance the iLet, including in a bihormonal system, as well as expand our product portfolio, including our patch pump in development, Mint. For example, we have completed over 20 pre-pivotal trials testing the algorithms in order to enhance its learning capabilities. We intend to continue to invest in research and development activities focused on improvements and enhancements to the iLet. Additionally, we intend to pursue marketing authorization or clearance for other indications in the United States in the future. Developing enhancements to the iLet and developing Mint has, and will continue to be expensive and time-consuming and has, and may continue to, divert management’s attention away from the commercialization of the iLet and Mint and divert financial resources from other operations. The success of any new products or new product enhancements, including marketing authorization or clearance for additional indications, will depend on several factors, including our ability to: •properly identify and anticipate physician and patient needs, and develop enhancements to meet those needs; •demonstrate, if required, the safety and effectiveness of new enhancements to our products, including additional indications, with data from preclinical studies and clinical trials; 42 •obtain in a timely manner the necessary marketing authorization or clearance for new enhancements to the iLet, product modifications or expanded indications; •avoid infringing upon the intellectual property rights of third parties; •comply with all applicable laws and regulations, including those governing the marketing of new devices or modified products; •develop an effective and dedicated sales and marketing team to provide adequate education and training to potential users of the iLet; and •receive adequate coverage and reimbursement for procedures performed with the iLet. While we have commercialized the iLet as an automated insulin dosing system cleared for the treatment of T1D in adults and children six years of age and older, we may not be successful in expanding the configurations or indications and developing and commercializing new products or product enhancements. This could negatively impact our ability to achieve and maintain market share and increase our revenue, which could have a material adverse effect on our business, financial condition and results of operations. Risks Related to Government Regulation We and our suppliers are subject to ongoing regulatory obligations and continued regulatory review, which may result in significant additional expense and subject us to penalties if we fail to comply with applicable regulatory requirements. Once we obtain marketing authorization or clearance for FDA-regulated products, such as our iLet and any future products, we and such products will be subject to continued and pervasive regulatory review, oversight, requirements, and periodic inspections by the FDA and other domestic and foreign regulatory bodies governing, among other things, the manufacture, marketing, advertising, reporting, sale, promotion, import, export, registration, and listing of our products. For example, medical device manufacturers must submit periodic reports to the FDA as a condition of obtaining marketing authorization or clearance. These reports include information about failures and certain adverse events associated with the device after its marketing authorization or clearance. Failure to submit such reports, or failure to submit the reports in a timely manner, could result in enforcement action by the FDA. Following its review of the periodic reports, the FDA might ask for additional information or initiate further investigation. In particular, unless exempt, we and our suppliers are required to comply with the FDA’s QMSR for medical device products and cGMPs for any approved drug products, such as glucagon if it is ultimately approved, and other regulations enforced outside the United States which cover the manufacture of our products and the methods and documentation of the design, testing, production, control, quality assurance, labeling, packaging, storage and shipping of medical devices. Regulatory bodies, such as the FDA, enforce the QMSR and cGMPs and other regulations through periodic inspections. The failure by us or one of our suppliers to comply with applicable statutes and regulations administered by the FDA and other regulatory bodies, or the failure to timely and adequately respond to any adverse inspectional observations or product safety issues, could result in, among other things, any of the following enforcement actions and/or other negative consequences: •untitled letters, warning letters, fines, injunctions, consent decrees and civil penalties; •unanticipated expenditures to address or defend such actions; •customer notification, or orders for repair, replacement or refunds; •voluntary or mandatory recall or seizure of our current or future products; •administrative detention by the FDA of medical devices believed to be adulterated or misbranded; •operating restrictions, suspension or shutdown of production; •refusing our requests for marketing authorization or clearance of new products, or new intended uses or modifications to the iLet; •suspending or withdrawing marketing authorizations or clearances that have already been granted; and •criminal prosecution. If any of these actions were to occur, our reputation would be harmed and our product sales and profitability would be adversely impacted. Furthermore, our key component suppliers may not currently be or may not continue to be in compliance with all applicable regulatory requirements which could result in our failure to manufacture our products on a timely basis and in the required quantities, if at all. Later discovery of previously unknown problems with our products, including manufacturing problems, or failure to comply with regulatory requirements such as the QMSR, may result in changes to labeling, restrictions on such products or manufacturing 43 processes, withdrawal of the products from the market, voluntary or mandatory recalls, a requirement to repair, replace or refund the cost of any medical device we manufacture or distribute, fines, suspension of regulatory approvals, product seizures, injunctions or the imposition of civil or criminal penalties which would adversely affect our business, operating results and prospects. In addition, the FDA may change its marketing authorization or clearance policies, adopt additional regulations or revise existing regulations, or take other actions, which may prevent or delay marketing authorization or clearance of any product candidate under development or impact our ability to modify any products authorized for market on a timely basis. Such policy or regulatory changes could impose additional requirements upon us that could delay our ability to obtain marketing authorizations or clearances, increase the costs of compliance or restrict our ability to maintain any marketing authorizations or clearances we have obtained. For example, in February 2024, the FDA issued a final rule to amend and replace the former Quality System Regulation, which set forth the FDA’s current good manufacturing practice requirements for medical devices, to align more closely with the International Organization for Standardization standards. Specifically, this final rule, which went into effect on February 2, 2026, established the QMSR, which among other things, incorporates by reference the quality management system requirements of ISO 13485:2016. Although the FDA has stated that the standards contained in ISO 13485:2016 are substantially similar to those set forth in the former Quality System Regulation, it is unclear the extent to which this final rule, once effective, could impose additional or different regulatory requirements on us that could increase the costs of compliance or otherwise negatively affect our business. If we are unable to comply with the QMSR or with any other changes in the laws or regulations enforced by the FDA or comparable regulatory authorities, we may be subject to enforcement action, which could have an adverse effect on our business, financial condition and results of operations. Additionally, the U.S. Supreme Court’s June 2024 decision in Loper Bright Enterprises v. Raimondo overturned the longstanding Chevron doctrine, under which courts were required to give deference to regulatory agencies’ reasonable interpretations of ambiguous federal statutes. The Loper decision could result in additional legal challenges to regulations and decisions issued by federal agencies, including the FDA, on which we rely. Any such legal challenges, if successful, could have a material impact on our business. Additionally, the Loper decision may result in increased regulatory uncertainty, inconsistent judicial interpretations, and other impacts to the agency rulemaking process, any of which could adversely impact our business and operations. We cannot predict the likelihood, nature or extent of government regulation that may arise from future legislation or administrative action, either in the United States or abroad. If we are slow or unable to adapt to changes in existing requirements or the adoption of new requirements or policies, or if we are not able to maintain regulatory compliance, we may be subject to enforcement action and we may not achieve or sustain profitability, which would harm our business, financial condition, results of operations and prospects. In addition, even after we have obtained marketing authorization or clearance for a product, the FDA has the power to require us to conduct post marketing studies, such as under a 522 Order, which is an order by the FDA to conduct a post-market study of an authorized or cleared medical device. We are subject to a post-market surveillance order issued by the FDA for our iLet. If the FDA determines that our iLet does not perform as anticipated, or if the FDA identifies new concerns related to the safety and effectiveness of the device, we may need to make changes to or recall or withdraw the iLet from the field, which could harm our business. These studies can be very expensive and time-consuming to conduct. Any failure to comply with ongoing regulatory requirements may significantly and adversely affect our ability to commercialize and generate revenue from our products. If regulatory sanctions are applied or if marketing authorization or clearance is withdrawn, it would have a material adverse effect on our business, financial condition and results of operations. In June 2025, the FDA conducted an inspection of our Irvine, California facility. Following the inspection, the FDA issued a Form 483. We initiated remediation activities and followed our communicated plan to address the FDA’s observations. We submitted our response and provided multiple updates to the FDA regarding the status of our remediation efforts. On January 29, 2026, we received a Warning Letter from the FDA following such inspection. In the Warning Letter, the FDA cited deficiencies in the response letters we sent to the FDA following the FDA’s issuance of the Form 483. The Warning Letter highlights non-conformities observed by the FDA in relation to our Quality Management System, Medical Device Reporting, and Correction and Removals, which were previously communicated by the FDA in the Form 483. The Warning Letter does not restrict our ability to produce, market, manufacture or distribute our products, nor does it restrict our ability to seek FDA 510(k) clearance of new products. We take the observations described in the Warning Letter seriously and have been regularly updating the FDA on the progress we have made in improving our quality management system in the areas outlined by the FDA in the Warning Letter. We intend to continue providing these regular updates to the FDA until the Warning Letter is resolved. We cannot provide assurances that the FDA will be satisfied with our response or an expected timeline for resolutions of the matters included in the Warning Letter. Until the deficiencies cited in the Warning Letter are resolved to the FDA’s satisfaction, additional legal or regulatory action may be taken without further notice. We do not expect the Warning Letter to materially impact our previously disclosed guidance that we expect to fully commercialize Mint by the end of the second quarter of 2027, subject to regulatory clearance by the FDA. The FDA can also publish Safety Communications or Letters to Health Care Providers when the agency becomes aware of new issues involving a specific product or, more broadly, a product family. These communications are posted on the FDA’s website and describe the FDA’s analysis of a current issue and provide specific regulatory approaches and clinical recommendations for patient management. If such communications occur it may harm our reputation and prevent us from generating revenue. 44
