Dexcom (DXCM) Risk Factors

In March 2018, via the de novo process, the FDA classified the G6 and substantially equivalent devices of this generic type (i.e., "integrated continuous glucose monitoring systems" or "iCGMs") into Class II, meaning that going forward products of this generic type may utilize the 510(k) pathway. Since then we have received 510(k) clearances for modifications to the G6 and approval for G7. Any subsequent modifications of our cleared products that could significantly affect their safety or effectiveness (for example, a significant change in design or manufacture), or that would constitute a major change in its intended use, will require us to obtain a new 510(k) clearance or could require a new de novo submission or a PMA. The FDA requires each manufacturer to make this determination initially, but the FDA may review any such decision and may disagree with a manufacturer's determination. If the FDA disagrees with a manufacturer's determination, the FDA may require the manufacturer to cease marketing and/or recall the modified device until appropriate clearance or approval is obtained. Under these circumstances, the FDA may also subject a manufacturer to significant regulatory fines or other penalties. If future product candidates are not deemed by the FDA to meet the criteria for submission under the 510(k) pathway, or for down-classification under the de novo process or otherwise, we would need to pursue a PMA. The PMA process requires us to prove the safety and effectiveness of our systems to the FDA's satisfaction. This process can be expensive, prolonged and uncertain, requires detailed and comprehensive scientific and human clinical data, and may never result in the FDA granting a PMA. The FDA's de novo classification of our G6 system under the generic name "integrated continuous glucose monitoring system," makes it a predicate device for future 510(k) submissions. Complying with this classification requires ongoing compliance with the general controls required by the federal Food Drug and Cosmetic Act and the special controls specified by the FDA's G6 order as a Class II device. Any future system or expanded indications for use of current generation systems will require approval of the applicable regulatory authorities. In addition, we intend to seek either 510(k) clearances or PMA approvals for certain changes and modifications to our existing software platform, but cannot predict when, if ever, those changes and modifications will be approved. The FDA can refuse to grant a 510(k) clearance or a de novo request for marketing authorization, or delay, limit or deny approval of a PMA application or supplement for many reasons, including: - the system may not be deemed by the FDA to be substantially equivalent to appropriate predicate devices under the 510(k) pathway;- the system may not satisfy the FDA's safety or effectiveness requirements;- the data from pre-clinical studies and clinical trials may be insufficient to support clearance or approval;- the manufacturing process or facilities used may not meet applicable requirements; and - changes in FDA approval policies or adoption of new regulations may require additional data. Even if approved or cleared by the FDA or foreign regulatory agencies, future generations of our CGM systems, expanded indications for use of current and future generation CGM systems, our software platforms or any other CGM system under development, may not be cleared or approved for the indications that are necessary or desirable for successful commercialization. We may not obtain the necessary regulatory approvals or clearances to market these CGM systems in the United States or outside of the United States. Any delay in, or failure to receive or maintain, clearance or approval for our products could prevent us from generating revenue from these products. The uncertain timing of regulatory approvals for future generations of our products could subject our current inventory to excess or obsolescence charges, which could have an adverse effect on our business, financial condition and operating results.

In response to perceived increases in health care costs in recent years, there have been and continue to be proposals by the federal government, state governments, regulators, and third-party payors to control these costs and, more generally, to reform the U.S. health care system. Certain of these proposals could limit the prices we are able to charge for our products or the amounts of reimbursement available for our products and could limit the acceptance and availability of our products. In November 2020, the OIG published a Special Fraud Alert addressing manufacturer Speaker Programs, signaling both a more narrow government view of AKS compliance with respect to such programs as well as the potential for increased enforcement in this space by government oversight agencies such as the OIG and DOJ. In March 2022, the Advanced Medical Technology Association, or AdvaMed, announced revisions to its Code of Ethics on Interactions with Health Care Professionals, or Code. The revised Code, effective June 2022, addressed concerns noted in the OIG's Special Fraud Alert, addressing things like virtual meetings, speaker programs and alcohol at events. The revised Code also addresses value-based care arrangements. We continue to assess industry responses to the Special Fraud Alert and have and may continue to make modifications to certain aspects of our speaker programs, which may have a detrimental impact on our ability to educate healthcare providers about our products and to promote use of our products, and which may in turn lead to decreased product sales and negatively impact our business, financial condition and results of operations. Comprehensive healthcare legislation, signed into law in the United States in March 2010, titled the Patient Protection and Affordable Care Act, as amended by the Health Care and Education Affordability Reconciliation Act of 2010, collectively, the ACA, imposes certain stringent compliance, recordkeeping, and reporting requirements on companies in various sectors of the life sciences industry, and enhanced penalties for non-compliance. Despite the ACA going into effect over a decade ago, there have been numerous legal and Congressional challenges to the law's provisions and the effect of certain provisions have made compliance costly. We cannot predict what additional new legislation, agency priorities, and rulemaking may be on the horizon as the United States continue to reassess how it pays for healthcare. As a result, we cannot quantify or predict what impact any changes might have on our business and results of operations. However, any changes that lower reimbursement for our products could materially and adversely affect our business, financial condition and results of operations. Other legal, regulatory and commercial policy influences are subjecting our industry to significant changes, and we cannot predict whether new regulations or policies will emerge from U.S. federal or state governments, foreign governments, or third-party payors. Government and commercial payors may, in the future, consider healthcare policies and proposals intended to curb rising healthcare costs, including those that could significantly affect reimbursement for healthcare products such as our systems. These policies have included, and may in the future include: basing reimbursement policies and rates on clinical outcomes, the comparative effectiveness, and costs, of different treatment technologies and modalities; imposing price controls and taxes on medical device providers; and other measures. Future significant changes in the healthcare systems in the United States or elsewhere could also have a negative impact on the demand for our current and future products. These include changes that may reduce reimbursement rates for our products and changes that may be proposed or implemented by the current or future laws or regulations.

We have received, and may continue to receive, numerous inquiries from hospitals around the country about the use of our CGM devices to remotely monitor COVID-19 patients admitted into the hospital. Following direct communication with the FDA regarding the potential use of our CGM devices in a hospital or other in-patient setting, the FDA notified us on April 1, 2020 that in an exercise of its enforcement discretion it will not object, in the context of the COVID-19 pandemic, to Dexcom providing CGM devices and support to users to enable real-time remote patient monitoring in hospitals and other healthcare facilities, to support COVID-19 healthcare-related efforts, so long as we provide certain FDA-specified information with respect to the unique challenges that CGM technologies can raise in the hospital environment. As a condition of its exercise of enforcement discretion, the FDA has advised that we communicate the following information related to implementing the use of CGM systems for remote monitoring of hospitalized patients: - Hospitals should consider whether they have the resources and expertise necessary to adequately implement CGM use and provide appropriate training to healthcare providers. - CGM glucose results are less accurate than blood glucose results obtained using traditional testing methods (e.g., lab glucose, blood glucose meters). Users should consider all CGM glucose information (e.g., trend) along with individual glucose values, and interpret CGM results in the context of the full clinical picture. - CGM systems are subject to interferences that may generate falsely high and falsely low glucose readings. Levels of interference depend on drug concentration; substances that may not significantly interfere in non-hospitalized patients may interfere when used in the hospital setting because of higher dose levels. Most drugs used in hospital or critical care settings have not been evaluated and their interference with CGM systems is unknown. Known interferences vary by CGM brand, and can include Acetaminophen, Ascorbic acid, Hydroxyurea, or other reducing drugs/ compounds. - Poor peripheral blood perfusion may cause inaccurate sensor readings. CGM results should be interpreted considering accompanying patient conditions and medications. Other clinical conditions may also cause inaccurate readings. Our provision of our CGM systems to hospitals and other healthcare facilities for use have and will continue to have the above notice. In February 2022, we received Breakthrough Device designation for our G6 CGM system in the hospital setting. The FDA's Breakthrough Device designation is designed to expedite the development and regulatory review of medical devices that hold the potential for more effective treatment or diagnosis of life-threatening or irreversibly debilitating disease or condition. We are not actively promoting for inpatient use, but if we supply them to such facilities as currently permitted by the FDA, this supply could present an increased risk of product liability claims and associated damages should an adverse event occur. Given that our CGM devices have not yet been fully evaluated or tested by either us or the FDA to the extent that would be required in standard circumstances for product development and marketing authorization, there could be unknown or unanticipated risks presented by use in this environment. The FDA can also decide, at any time, to change its position regarding its Breakthrough Device Designation and/or enforcement discretion for our devices, and require that we seek marketing authorization for this additional intended use by submitting a 510(k) premarket notification, or that we seek and obtain Emergency Use Authorization. The COVID-19 public health emergency declared by the Department of Health and Human Services expired on May 11, 2023. While the end of the public health emergency does not by itself impact the FDA's ability to authorize devices for emergency use, and the FDA has published guidance for transition plans for medical devices that fall within enforcement policies issued during the COVID-19 pandemic. We will continue to closely monitor regulatory developments that impact our products, business, or financial results, including those relating to FDA enforcement discretion and Breakthrough Device Designation for the provision of our CGM systems in the hospital setting.

Development or changes to the FDA or foreign regulatory approval standards and processes, including both legal and policy changes, could also delay or prevent the approval of our products submitted for review. For example, medical device cybersecurity continues to be an area of focus for and evolving guidance from FDA. Additionally, at the end of 2022, Congress passed the Food and Drug Omnibus Reform Act of 2022, or FDORA which (among other things), and similarly to the 2022 FDA Guidance, requires device sponsors to submit clinical trial diversity action plans outlining the goals for increasing representation of participants from racial and ethnic minority populations that have been underrepresented in clinical trials. Any change in the laws or regulations that govern the clearance and approval processes relating to our current and future products could make it more difficult and costly to obtain clearance or approval for new products, or to produce, market and distribute existing products. The data contained in our submissions, including data drawn from our clinical trials, may not be sufficient to support clearance or approval of our products or additional or expanded indications. Medical device company stock prices have declined significantly in certain circumstances where companies have failed to meet expectations in regards to the timing of regulatory approval. If the FDA's response causes product approval delays, or is not favorable for any of our products, our stock price (and the market price of our senior convertible notes) could decline substantially. It is uncertain how these potential changes may impact our ability to gain clearance or approval from FDA for our products in the future.

Many laws and regulations, notably those adopted in connection with the Sarbanes-Oxley Act of 2002, the Dodd-Frank Wall Street Reform and Consumer Protection Act, new SEC regulations and The Nasdaq Stock Market listing rules, impose obligations on public companies, such as ours, which have increased the scope, complexity and cost of corporate governance, reporting and disclosure practices. Compliance with these laws and regulations, including enhanced new disclosures, has required and will continue to require substantial management time and oversight and the incurrence of significant accounting and legal costs. Additionally, changes to existing accounting rules or standards, such as the potential requirement that U.S. registrants prepare financial statements in accordance with International Financial Reporting Standards, may adversely impact our reported financial results and business, and may require us to incur greater accounting fees. These laws, regulations, and standards are subject to varying interpretations, in many cases due to their lack of specificity, and, as a result, their application in practice may evolve over time as new guidance is provided by regulatory and governing bodies. This could result in continuing uncertainty regarding compliance matters and higher costs necessitated by ongoing revisions to disclosure and governance practices. We intend to continue to invest resources to comply with evolving laws, regulations, and standards, and this investment may result in increased general and administrative expenses and a diversion of management's time and attention from revenue-generating activities to compliance activities. If our efforts to comply with new laws, regulations, and standards differ from the activities intended by regulatory or governing bodies due to ambiguities related to their application and practice, regulatory authorities may initiate legal proceedings against us and our business may be adversely affected.

The healthcare industry generally, and our business specifically, is subject to extensive foreign, federal, state and local laws and regulations, including those relating to: - authorizations necessary for the clinical investigation and commercial marketing of products;- the pricing of our products and services;- the distribution of our products and services;- the dispensing of our products;- billing for or causing the submission of claims for our products and services;- financial relationships with physicians and other referral sources;- inducements and courtesies given to physicians and other health care providers and patients;- labeling, advertising and promoting products;- the characteristics and quality of our products and services;- communications with payors and physicians and other healthcare stakeholders;- confidentiality, maintenance and security issues associated with medical records and individually identifiable health and other personal information;- medical device adverse event reporting;- prohibitions on kickbacks, including the Anti-Kickback Statute and related laws and/or regulations;- any scheme to defraud any healthcare benefit program;- physician and other healthcare professional payment disclosure requirements;- use and disclosure of personal health information;- privacy of health information and personal information;- data protection and data localization;- mobile communications;- patient access and non-discrimination;- patient consent;- false claims; and - licensure. These laws and regulations are extremely complex and, in many cases, still evolving. If our operations are found to violate any of the foreign, federal, state or local laws and regulations which govern our activities, we may be subject to litigation, government enforcement actions, and applicable penalties associated with the violation, potentially including civil and criminal penalties, damages, fines, exclusion from participation in certain payor programs or curtailment of our operations. Compliance obligations under these various laws are oftentimes detailed and onerous, further contributing to the risk that we could be found to be out of compliance with particular requirements. The risk of being found in violation of these laws and regulations is further increased by the fact that many of them have not been fully interpreted by the regulatory authorities or the courts, particularly with respect to new and emerging technologies and remote delivery of services, and their provisions are open to a variety of interpretations. The FDA, CMS, OIG, OCR, FTC, Department of Justice, states' attorneys general and other governmental authorities actively enforce the laws and regulations discussed above. In the United States, medical device manufacturers have been the target of numerous government prosecutions and investigations alleging violations of law, including claims asserting impermissible off-label promotion of medical devices, payments intended to influence the referral of federal or state healthcare business, and submission of false claims for government reimbursement. While we make every effort to comply with applicable laws, we cannot rule out the possibility that the government or other third parties could interpret these laws differently and challenge our practices under one or more of these laws. This likelihood of allegations of non-compliance is increased by the fact that under certain federal and state laws applicable to our business, individuals may bring an action on behalf of the government alleging violations of such laws, and potentially be awarded a share of any damages or penalties ultimately awarded to the applicable government body. The FDA and the FTC share oversight of medical device promotion. The FDA has broad authority over device marketing (including assessment and oversight of safety and effectiveness) and over FDA-approved "promotional labeling," while the FTC has authority over "advertising" for most medical devices (i.e., non-"restricted" devices, such as ours). Any action against us alleging a violation of these laws or regulations, even if we successfully defend against it, could cause us to incur significant legal expenses and divert our management's time and attention from the operation of our business, and have a material effect on our business. In addition, the laws and regulations impacting or affecting our business may change significantly in the future, which may adversely affect our business. A review of our business by courts or regulatory authorities may result in a determination that could adversely affect our operations. Also, the regulatory environment applicable to our business may change in a way that restricts or adversely impacts our operations.

We conduct limited commercial and marketing efforts in certain international markets in the Asia-Pacific, North America and Europe, Middle East and Africa regions, with respect to our CGM systems and may seek to market our products in other regions in the future. Outside the United States, we can market a product only if we receive a marketing authorization and, in some cases, pricing approval, from the appropriate regulatory authorities. The marketing authorization procedures vary among countries and can involve additional testing, and the time required to obtain any required authorization or approval may differ from that required to obtain FDA marketing authorization(s). Foreign regulatory authorization or approval processes may include all of the risks associated with obtaining FDA marketing authorization(s) in addition to other risks. We may not obtain foreign regulatory authorizations or approvals on a timely basis, if at all. Obtaining a marketing authorization from the FDA does not ensure authorization or approval by regulatory authorities in other countries will follow, and authorization or approval by one foreign regulatory authority does not ensure authorization or approval by regulatory authorities in other foreign countries or by the FDA. In addition, in order to obtain the authorization to market our products in certain foreign jurisdictions, in some cases we may need to obtain a Certificate to Foreign Government from the FDA. The FDA may refuse to issue a Certificate to Foreign Government if significant compliance-related concerns are identified. As a result, there are a range of factors that could preclude or impede our ability to file for regulatory approvals or marketing authorizations or to receive necessary approvals or authorizations to commercialize our products in any market outside the United States on a timely basis, or at all.

The U.S. Department of the Treasury's Office of Foreign Assets Control, and the Bureau of Industry and Security at the U.S. Department of Commerce, administer certain laws and regulations that restrict U.S. persons and, in some instances, non-U.S. persons, in conducting activities, and transacting business with or making investments in certain countries, governments, entities and individuals subject to U.S. economic sanctions. Due to our international operations, we are subject to such laws and regulations, which are complex, restrict our business dealings with certain countries and individuals, and are constantly changing. Further restrictions may be enacted, amended, enforced or interpreted in a manner that materially impacts our operations. Violations of these regulations are punishable by civil penalties, including fines, denial of export privileges, injunctions, asset seizures, debarment from government contracts and revocations or restrictions of licenses, as well as criminal fines and imprisonment. We have established procedures designed to assist with our compliance with such laws and regulations. However, we have only limited experience dealing with these laws and regulations and we cannot guarantee that our procedures will effectively prevent us from violating these regulations in every transaction in which we may engage. Any such violation could adversely affect our reputation, business, financial condition and results of operations.

Healthcare companies are subject to numerous investigations and inquiries by various governmental agencies. Further, under the False Claims Act, private parties have the right to bring qui tam, or "whistleblower," suits against companies that submit false claims for payments to, or improperly retain overpayments from, the government. Some states have adopted similar state whistleblower and false claims provisions. Depending upon whether the underlying conduct alleged in such inquiries or investigations could be considered systemic, any resolution of any such investigations could have a material, adverse effect on our financial position and results of operations. Governmental agencies and their agents, such as CMS Medicare Administrative Contractors and other CMS contractors, as well as the OIG, state Medicaid programs, and other state and federal agencies may conduct audits of our operations, relating to covered items and services including those furnished to beneficiaries, health care providers and distributors. Commercial and government-funded managed care payors may conduct similar post-payment audits. Depending on the nature of the conduct found in such audits and whether the underlying conduct could be considered systemic, the resolution of these audits could have a material adverse effect on our financial position and results of operations. Our compliance program includes internal audit and monitoring functions designed to identify potential issues and facilitate remediation as appropriate. Any future investigations of our executives, our managers or us could result in significant liabilities or penalties to us, as well as adverse publicity. Even if we are found to have complied with applicable law, the investigation or litigation may pose a considerable expense and would divert management's attention, and have a potentially negative impact on the public's perception of us, all of which could negatively impact our financial position and results of operations. Further, should we be found out of compliance with any of these laws, regulations or programs, depending on the nature of the findings, our business, our financial position and our results of operations could be negatively impacted.

Our business exposes us to the risk of product liability claims that is inherent in the testing, manufacturing and marketing of medical devices, including those which may arise from the misuse (including system hacking or other unauthorized access by third parties to our systems) or malfunction of, or design flaws in, our products. This liability may vary based on the FDA classification associated with our devices. Notably, the classification of our G6 and G7 systems as Class II medical devices is likely to weaken our ability to rely on federal preemption of state law claims that assert liability against us for harms arising from use of those systems. We may be subject to product liability claims if our products cause, or merely appear to have caused, an injury. Claims may be made by customers, healthcare providers or others selling our products. The risk of product liability claims may increase given that G6 and G7 do not require confirmatory finger sticks when making treatment decisions or finger stick tests each day for calibration, although it does require finger stick tests when symptoms do not match readings and when readings are unavailable. The risk of claims may also increase if our products are subject to a product recall or seizure. An example of the difficulty of complying with the regulatory requirements associated with the manufacture of our products, we issued notifications to our customers regarding the audible alarms and alerts associated with our receivers. Although we have insurance at levels that we believe is appropriate, this insurance is subject to deductibles and coverage limitations. Our current product liability insurance may not continue to be available to us on acceptable terms, if at all, and, if available, the coverage may not be adequate to protect us against any future product liability claims. Further, if additional products are approved for marketing, we may seek additional insurance coverage. If we are unable to obtain insurance at an acceptable cost or on acceptable terms with adequate coverage or otherwise protect against potential product liability claims, we will be exposed to significant liabilities, which may harm our business. A product liability claim, recall or other claims with respect to uninsured liabilities or for amounts in excess of insured liabilities could result in significant costs and significant harm to our business. We may be subject to claims against us even if the apparent injury is due to the actions of others or misuse of the device or a partner device. Our customers, either on their own or following the advice of their physicians, may use our products in a manner not described in the products' labeling and that differs from the manner in which it was used in clinical studies and approved by the FDA. For example, our current systems are designed to be used by an individual continuously for up to 10 days for our G6 and G7 systems, but the individual might be able to circumvent the safeguards designed into the systems and use the products for longer than 10 days. Off-label use of products by customers is common, and any such off-label use of our products could subject us to additional liability, or require design changes to limit this potential off-label use once discovered. In addition, other regulatory agencies may in the future approve similar diabetes treatment indications. We expect that such diabetes treatment indications could expose us to additional liability. These liabilities could prevent or interfere with our product commercialization efforts. Defending a suit, regardless of merit, could be costly, could divert management attention and might result in adverse publicity, which could result in the withdrawal of, or inability to recruit, clinical trial volunteers or result in reduced acceptance of our products in the market.

Our research and development and clinical processes involve the handling of potentially harmful biological materials as well as hazardous materials. We are subject to international and domestic (including federal, state and local) laws, rules and regulations governing the use, handling, storage and disposal of hazardous and biological materials and we incur expenses relating to compliance with these laws and regulations. If violations of environmental, health and safety laws occur, we could be held liable for damages, penalties and costs of remedial actions. These expenses or this liability could have a significant negative impact on our financial condition. We may violate environmental, health and safety laws in the future as a result of human error, equipment failure or other causes. Environmental laws could become more stringent over time, imposing greater compliance costs and increasing risks and penalties associated with violations. We are subject to potentially conflicting and changing regulatory agendas of political, business and environmental groups. Changes to or restrictions on permitting requirements or processes, hazardous or biological material storage or handling might require unplanned capital investment or relocation. Failure to comply with new or existing laws or regulations could harm our business, financial condition and results of operations. General Risk Factors

We rely on clinical investigators and clinical sites to enroll patients in our clinical trials, and other third parties to manage the trial and to perform related data collection and analysis. However, we may not be able to control the amount and timing of resources that clinical sites may devote to our clinical trials. If these clinical investigators and clinical sites fail to enroll a sufficient number of patients in our clinical trials or fail to ensure compliance by patients with clinical protocols or fail to comply with regulatory requirements, we will be unable to complete these trials, which could prevent us from obtaining regulatory approvals for our products. Our agreements with clinical investigators and clinical sites for clinical testing place substantial responsibilities on these parties and, if these parties fail to perform as expected, our trials could be delayed or terminated. If these clinical investigators, clinical sites or other third parties do not carry out their contractual duties or obligations or fail to meet expected deadlines, or if the quality or accuracy of the clinical data they obtain is compromised due to their failure to adhere to our clinical protocols, regulatory requirements or for other reasons, our clinical trials may be extended, delayed or terminated, or the clinical data may be rejected by the FDA, and we may be unable to obtain regulatory approval for, or successfully commercialize, our products.

- the FDA or other regulatory authorities do not approve a clinical trial protocol or a clinical trial, or place a clinical trial on hold;- patients do not enroll in clinical trials at the rate we expect;- patients or study site personnel who do not comply with clinical trial protocols;- patient follow-up does not occur at the rate we expect;- patients experience adverse side effects;- patients die during a clinical trial, even though their death may not be related to our products;- institutional review boards and third-party clinical investigators may delay or reject our clinical trial protocol;- third-party clinical investigators decline to participate in a trial or do not perform a trial on our anticipated schedule or consistent with the investigator agreements, clinical trial protocol, good clinical practices or other FDA or institutional review board requirements;- we or third-party organizations do not perform data collection, monitoring or analysis in a timely or accurate manner or consistent with the clinical trial protocol or investigational or statistical plans;- third-party clinical investigators have significant financial interests related to us or the study that the FDA deems to make the study results unreliable, or we or clinical investigators fail to disclose such interests;- regulatory inspections of our clinical trials or manufacturing facilities may results in allegations or findings of noncompliance and, among other things, require us to undertake corrective action or suspend or terminate our clinical trials;- changes in governmental regulations, policies or administrative actions applicable to our trial protocols;- the interim or final results of the clinical trial are inconclusive or unfavorable as to safety or efficacy; and - the FDA concludes that the results from our trial and/or trial design are inadequate to demonstrate safety and effectiveness of the product. Further, health epidemics could limit or restrict our ability to initiate, conduct or continue our clinical trials. Delays and disruption in our clinical trials could result in delays for expanded FDA clearance or approval of our products. The results of pre-clinical studies or other forms of early product testing do not necessarily predict future clinical trial results, and prior clinical trial results might not be repeated in subsequent clinical trials. Additionally, the FDA may disagree with our interpretation of the data from our pre-clinical studies, product testing, and clinical trials, or may find the clinical trial design, conduct or results inadequate to prove safety or effectiveness, and may require us to pursue the development of additional data, which could further delay the approval of our products. If we are unable to demonstrate the safety and effectiveness of our products in our clinical trials to the FDA's satisfaction, where clinical data are required, we will be unable to obtain regulatory approval to market our products in the United States. In addition, the data we collect from our current clinical trials, our pre-clinical studies and other clinical trials may not be sufficient to support FDA approval, even if our endpoints are met. We may also conduct clinical studies to demonstrate the relative or comparative effectiveness of CGM systems for the treatment of diabetes. These types of studies, which often require substantial investment and effort, may not show adequate, or any, clinical benefit or value for the use of CGM systems.

To support current and any future additional PMA, 510(k), de novo applications or supplements, we together with our partners, must successfully complete pre-clinical studies, bench-testing, and in some cases clinical trials that will demonstrate that the product is safe and effective. Product development, including pre-clinical studies and clinical trials, is a long, expensive and uncertain process and is subject to delays and failure at any stage. Furthermore, the data obtained from the studies and trials may be inadequate to support approval of an application and the FDA may request additional clinical data in support of those applications, which may result in significant additional clinical expenses and may delay product approvals. While we have in the past obtained, and may in the future obtain, an investigational device exemption, or IDE, prior to commencing clinical trials for our products, FDA approval of an IDE application permitting us to conduct testing does not mean that the FDA will consider the data gathered in the trial to be sufficient to support approval of a PMA, de novo or 510(k) application or supplement, even if the trial's intended safety and effectiveness endpoints are achieved.

Based on our experience, complications from use of our products may include sensor errors, sensor failures, broken or detached sensor wires, or skin irritation under the adhesive dressing of the sensor. Inflammation or redness, swelling, minor infection, and minor bleeding at the sensor insertion site are also possible risks with an individual's use of our products. However, if unanticipated long-term side-effects result from the use of our products or other glucose monitoring systems we have under development, we could be subject to liability and the adoption of our systems may become more limited. With respect to our G6 systems, our clinical trials have been limited to ten days of continuous use. It is possible that the data from our clinical studies and trials may not be indicative of long-term patient outcomes. We cannot assure you that repeated, long-term use would not result in unanticipated adverse effects, potentially even after the sensor is removed.

We rely on information technology and telephone networks and systems, including the Internet, to process and transmit sensitive electronic information and to manage or support a variety of business processes and activities, including sales, billing, customer service, procurement and supply chain, manufacturing, and distribution. We use enterprise information technology systems to record, process, and summarize financial information and results of operations for internal reporting purposes and to comply with regulatory financial reporting, legal, and tax requirements. System failures or outages, including any potential disruptions due to significantly increased global demand on certain cloud-based systems, or failures to adequately scale our data platforms and architectures support patient care could compromise our ability to perform these functions in a timely manner, which could harm our ability to conduct business or delay our financial reporting. Such failures could materially adversely affect our operating results and financial condition. Our information technology systems, some of which are managed by third parties, may be susceptible to damage, disruptions or shutdowns due to computer viruses, denial-of-service attacks, phishing attacks, ransomware or other malware, attacks by computer hackers (including nation states or state-sponsored organizations), failures during the process of upgrading or replacing software, databases or components thereof, power outages, hardware failures, telecommunication failures, user errors, natural disasters, terrorist attacks, the outbreak of wars or other armed conflicts, or catastrophic events. Although we have developed systems and processes that are designed to protect customer information and prevent data loss and other security breaches, including systems and processes designed to reduce the impact of a security breach at a third-party vendor, such measures cannot provide absolute security. In addition, certain countries have implemented or may implement legislative and technological actions that either do or can effectively regulate access to the internet, including the ability of internet service providers to limit access to specific websites or content. Other countries have attempted or are attempting to change or limit the legal protections available to businesses that depend on the internet for the delivery of their services. If our systems are breached or suffer severe damage, disruption or shutdown and we are unable to effectively resolve the issues in a timely manner, our business and operating results may significantly suffer and we may be subject to litigation, government enforcement actions and other actions for which we could face financial liability and other adverse consequences which may include: - additional government oversight of our operations;- loss of existing customers;- difficulty in attracting new customers;- problems in determining product cost estimates and establishing appropriate pricing;- difficulty in preventing, detecting, and controlling fraud;- disputes with customers, physicians, and other health care professionals;- increases in operating expenses, incurrence of expenses, including notification and remediation costs;- regulatory fines or penalties;- individual actions or class actions for damages;- loss of revenues (including through loss of coverage or reimbursement);- product development delays;- disruption of key business operations; and - diversion of attention of management and key information technology resources.

There are numerous and evolving risks to our cybersecurity and privacy from cyber threat actors. These cyber threat actors, whether internal of external to the Company, are becoming more frequent, sophisticated and coordinated in their attempts to access data, including third parties with whom the Company conducts business through, without limitation, malicious software; data privacy breaches by employees, insiders or others with authorized access; cyber or phishing-attacks; ransomware; attempts to gain unauthorized access to our data and systems; and other electronic security breaches. In the ordinary course of business, we collect and store sensitive information on our network, including intellectual property, proprietary business information and personally identifiable information of individuals, such as our customers and employees. The secure maintenance of this information and technology is critical to our business operations. We have implemented and deploy multiple layers of security measures to protect the confidentiality, integrity and availability of this data and the systems and devices that store and transmit such data. We utilize current security technologies, and our defenses are monitored and routinely tested internally and by external parties. Despite these efforts, threats from malicious persons and groups, new vulnerabilities and advanced new attacks against information systems create risk of cybersecurity incidents. These incidents can include, but are not limited to, gaining unauthorized access to digital systems for purposes of misappropriating assets or sensitive information, corrupting data, or causing operational disruption. Because the techniques used to obtain unauthorized access, disable or degrade service, or sabotage systems change frequently and may not immediately produce signs of intrusion, we may be unable to anticipate these incidents or techniques, timely discover them, or implement adequate preventative measures. Additionally, in response to the onset of the COVID-19 pandemic, we modified our business practices and initially implemented telework policies for certain categories of "non-essential" employees to the extent possible. We have since adopted a hybrid workplace model for our employees. Our hybrid workplace allows us to work together globally to bring our life-changing products to as many people as possible. This means we have some employees who work primarily onsite, some who work primarily offsite, and others who flex in and out of the office based on the needs of the business and the individual. We recognized the need for flexibility in our physical workplace during the COVID-19 pandemic, but also noted the potential benefits of a hybrid workplace to expand and retain our talent pool and reduce our real estate needs. The hybrid workplace does, however, introduce additional operational risk, including increased cybersecurity risk. These cyber risks include, among other risks, increased phishing, malware, and other cybersecurity attacks, vulnerability to, or disruptions of, our information technology infrastructure and systems to support remote operations, increased risk of unauthorized access, use or dissemination of confidential information, limited ability to restore the systems in the event of a systems failure or interruption, greater risk of a security breach resulting in destruction, alteration or misuse of valuable information, including proprietary business information and personally identifiable information of individuals, all of which could expose us to risks of data or financial loss, litigation and liability. These threats can come from a variety of sources, including criminal hackers, state-sponsored intrusions, industrial espionage and malfeasance by employees, contractors, or other insiders. Cyber threats may be generic, or they may be custom-crafted against our information systems or particular personnel. Over the past several years, cyberattacks have become more prevalent and much harder to detect and defend against. These threat actors may be able to penetrate our security measures, breach our information technology systems, misappropriate or compromise confidential and proprietary information of our company and our customers, cause system disruptions and shutdowns, or introduce ransomware, malware, or vulnerabilities into our products, systems, and networks or those of our customers and partners. Our network and storage applications, as well as those of our contractors, may be vulnerable to cyber-attack, malicious intrusion, malfeasance, loss of data privacy or other significant disruption and may be subject to unauthorized access by hackers, employees, consultants or other service providers. In addition, products, hardware, software or applications we develop, or which we procure from third parties, may contain defects in design or manufacture, security flaws, or other problems that could unexpectedly compromise information security or the operation of our products. Our third-party vendors may experience security incidents of varying severity, including but not limited to increased ransomware attacks, network intrusions, and unauthorized data exfiltration. Targeted cyber attacks or those that may result from a security incident directed at a third-party vendor could compromise our services and internal systems, resulting in interruptions, delays, or cessation of service that could disrupt business operations for us and our customers. Our proactive measures and remediation efforts may not be successful or timely. Unauthorized parties may also attempt to gain access to our systems or facilities through fraud, trickery or other forms of deceiving our employees, contractors and temporary staff. While we maintain cybersecurity insurance coverage there is no guarantee that it will be sufficient to cover the financial, legal, business, or reputational losses that may result from an interruption or breach of our systems. Our cybersecurity insurance includes coverage for a breach event covering expenses for notification, credit monitoring, investigation, crisis management, public relations and legal advice. Our cybersecurity insurance also provides coverage in relation to regulatory action defense including oversight, investigations and disclosure obligations as well as fines and penalties, potential payment card industry fines and penalties and costs related to cyber extortion; however, damages and claims arising from such incidents may not be covered and/or may exceed the amount of any coverage and do not cover the time and effort we incur investigating and responding to any incidents, which may be significant. We are and may continue to be subject to cybersecurity incidents that bypass our security measures. Such incidents may impact the integrity, availability or privacy of personal health information or other data subject to privacy laws or disrupt our information systems, devices or business, including our ability to deliver services to our customers. As a result, cybersecurity, physical security and the continued development and enhancement of our controls, processes and practices designed to protect our enterprise, information systems and data from attack, damage or unauthorized access remain a priority for us. As cyber threats continue to evolve, we may be required to expend significant additional resources to continue to modify or enhance our protective measures or to investigate and remediate any cybersecurity vulnerabilities. The occurrence of any of these events could result in: - harm to customers;- business interruptions and delays;- the loss, misappropriation, corruption or unauthorized access of data, confidential information or intellectual property;- litigation, including potential class action litigation, and potential liability under privacy, security and consumer protection laws or other applicable laws;- reputational damage;- significant remediation costs, including liability for stolen customer or employee information, repairing system damage, or providing benefit to affected customers or employees;- increase to insurance premiums; and - foreign, federal and state governmental inquiries, violations or sanctions, any of which could have a material, adverse effect on our financial position and results of operations.

We expect that sales of our CGM systems will account for substantially all of our product revenue for the foreseeable future. If and when we receive FDA or other regulators' marketing authorization for, and begin commercialization of, our next-generation CGM systems, we expect most patients will migrate onto those systems. In the periods leading up to the launch of new or upgraded versions of our CGM systems, however, our customers' anticipation of the release of those products may cause them to cancel, change or delay current period purchases of our current products, which could have a material adverse effect on our business, financial condition and results of operations. Notwithstanding our prior experience in marketing and selling our products, we might be unable to successfully expand the commercialization of our existing products or begin commercialization of our next-generation CGM systems on a wide-scale for a number of reasons, including the following: - our G6 and G7 systems prompt the user to replace the sensor no later than the tenth day, which might make it expensive for users;- widespread market acceptance of our products by health care professionals and people with diabetes will largely depend on our ability to demonstrate their relative safety, effectiveness, reliability, cost-effectiveness and ease of use;- the limited size of our sales force;- we may not have sufficient financial or other resources to adequately expand the commercialization efforts for our products;- expanded coverage opportunities for our competitors' CGM devices and supplies, including coverage for adjunctive CGMs, increasing competition in the marketplace;- our FDA and other regulatory authority marketing application submissions and reviews may be delayed, or cleared or approved with limited product indications and labeling;- we may not be able to manufacture our products in commercial quantities commensurate with demand or at an acceptable cost;- the uncertainties associated with establishing and qualifying new manufacturing facilities;- people with diabetes may need to incur the costs of single-point finger stick devices, in addition to our systems;- the relative immaturity of the CGM market internationally, and limited international reimbursement of CGM systems by third-party payors and government healthcare providers outside the United States;- the introduction and market acceptance of competing products and technologies, which may have a lower cost or price, allow for a convenience improvement and/or allow for improved accuracy and reliability;- the introduction and market acceptance of new drug therapies for the treatment and management of diabetes and related conditions, including obesity;- greater name or brand recognition and more established medical product distribution channels by some of our competitors;- our inability to obtain sufficient quantities of supplies timely and at appropriate quality levels from our single- or sole-source and other key suppliers;- our inability to manufacture products that perform in accordance with expectations of consumers; and - rapid technological change may make our technology and our products obsolete. In addition to the risks outlined above, our G6 and G7 systems are more invasive than many other self-monitored glucose testing systems, including single-point finger stick devices, and people with diabetes may be unwilling to insert a sensor in their body, especially if their current diabetes management involves no more than two finger sticks per day. Moreover, people with diabetes may not perceive the benefits of CGM and may be unwilling to change their current treatment regimens. Health care professionals may not recommend or prescribe our products unless and until (i) there is more long-term clinical evidence to convince them to alter their existing treatment methods, (ii) there are additional recommendations from prominent physicians that our products are effective in monitoring glucose levels, and (iii) reimbursement or insurance coverage is more widely available. In addition, market acceptance of our products by physicians and people with diabetes in Europe or other countries will largely depend on our ability to demonstrate their relative safety, effectiveness, reliability, cost-effectiveness and ease of use. If we are unable to do so, we may not be able to generate product revenue from our sales efforts in Europe or other countries. We cannot predict when, if ever, healthcare professionals, including physicians, and people with diabetes may adopt more widespread use of CGM systems, including our systems. We are also aware of the increasing use of GLP-1 products for the treatment of obesity and Type 2 diabetes. While we believe that GLP-1s are a companion product and used in conjunction with our CGM systems, these treatments could potentially compete with our CGM systems and reduce sales of our products. If our CGM systems do not achieve and maintain an adequate level of acceptance by people with diabetes, healthcare professionals, including physicians, and third party payors, our future revenue may be reduced and our business may be harmed.

As a medical device company, reimbursement from government and/or commercial third-party healthcare payors, including Medicare and Medicaid, is an important element of our success. The Centers for Medicare & Medicaid Services, or CMS, provides coverage for "Therapeutic Continuous Glucose Monitors" as durable medical equipment eligible for coverage under Medicare Part B. Coverage criteria for therapeutic CGMs is determined by CMS under national coverage determinations as well as by local Medicare Administrative Contractors under local coverage determinations. Therefore, Medicare reimbursement for our CGM devices is subject to various coverage conditions and often requires a patient-specific coverage analysis. Medicare does not cover any items or services that are not "reasonable and necessary." Medicare covers the CGM system, which includes supplies necessary for the use of the device, under the Durable Medical Equipment, or DME, benefit category. In order to be covered under this benefit, one component of the CGM system must meet the criteria for a durable medical device. To date, the receiver satisfied this criteria. To the extent that a receiver is not used by a Medicare beneficiary or CMS otherwise determines that the items and supplies ordered are not medically necessary, Medicare may not cover that CGM system or any associated supplies. We face a number of regulatory and commercial hurdles relating to wide-scale sales where a government or commercial third-party payor provides reimbursement, including sales to Medicare beneficiaries. If we are unable to successfully address these hurdles, reimbursement of our products may be limited to a smaller subset of people with diabetes covered by Medicare or to those people with diabetes covered by other third-party payors that have adopted policies for CGM devices allowing for coverage of these devices if certain conditions are met. Adverse coverage or reimbursement decisions relating to our products, or rescission or limitation of favorable determinations, by CMS, its Medicare Administrative Contractors, other state, federal or international payors, and/or third-party commercial payors could significantly reduce reimbursement, which could have an impact on the acceptance of, and demand for, our products and the prices that our customers are willing to pay for them. As of December 31, 2023, the eight largest private third-party payors, in terms of the number of covered lives, have issued coverage policies for the category of CGM devices. In addition, we have negotiated contracted rates with all of those third-party payors for the purchase of our current CGM systems by their members. Nevertheless, coverage and reimbursement-related barriers remain. Among other things, people with diabetes without insurance that covers our products bear the entire financial cost of using our products. In addition, in the United States, people with diabetes using existing single-point finger stick devices are generally reimbursed all or part of the product cost by Medicare or other third-party payors, which may be perceived as more advantageous for consumers. Further, while many third-party payors have adopted some form of coverage policy on CGM devices, in a sizeable percentage of cases, under durable medical equipment benefits, those coverage policies frequently are restrictive and require significant medical documentation and other requirements in order for policy holders to obtain reimbursement, and as a result, we have difficulty improving the efficiency of our customer service group. Moreover, it is not uncommon for governmental, including federal and/or state, agencies and their contractors to conduct periodic routine billing and compliance reviews that may entail extensive documentation requests, cooperation with which may require significant time and resources, and may result in identification of overpayments that may need to be refunded. The commercial success of our products in both domestic and international markets will substantially depend on whether timely and comprehensive third-party reimbursement is widely available for individuals that use them. CMS has adopted coverage guidelines for CGMs, which could have a favorable impact on us. Previously, Medicare coverage for CGM was only available to Medicare patients who take at least three doses of insulin a day, limiting CGM reimbursement for Medicare beneficiaries with intensive Type 1 and 2 diabetes. The Local Coverage Determination, or LCD, that CMS released in April 2023 extends Medicare CGM coverage to patients who use any insulin. Further, the LCD also allows coverage for patients not taking insulin if the patient has a history of problematic hypoglycemia. Nevertheless, third-party payors are increasingly attempting to contain healthcare costs by limiting both coverage and the level of reimbursement of new and existing medical devices, and, as a result, they may be restrictive, or they may not cover or provide adequate payment for our products. In order to obtain additional reimbursement arrangements, including under pharmacy benefits, we may have to agree to a net sales price lower than the net sales price we might charge in other sales channels. Our revenue may be limited by the continuing efforts of government and third-party payors to contain or reduce the costs of healthcare through various increasingly sophisticated means, such as leveraging increased competition, increasing eligibility requirements such as second opinions and other documentation, purchasing in a bundle, or redesigning benefits. In December 2021, CMS published a final rule expanding the classification of DME under Medicare Parts B & C to include adjunctive CGMs (i.e., CGMs that do not replace standard blood glucose monitors for treatment decisions) and related supplies. This final rule expands coverage of CGMs to include a large competitor's competing device, which may negatively impact our sales. We are unable to predict what effect the current or any future healthcare reform will have on our business, or the effect these matters will have on our customers. Our dependence on the commercial success of our current CGM systems makes us particularly susceptible to any cost containment or reduction efforts. Accordingly, unless government and other third-party payors provide adequate coverage and reimbursement for our current CGM systems or any future products we may develop, people without coverage who have diabetes may not use our products. Furthermore, payors are increasingly basing reimbursement rates on factors such as prior approvals and the effectiveness of the product, clinical outcomes associated with the product, and any factors that negatively impact the effectiveness or clinical outcomes (or cause a perception of any such negative impact), such as the results of a clinical trial, a product defect, or a product recall, which could negatively impact the reimbursement rate. Also, the trends toward managed healthcare in the United States and legislative efforts intended to reduce the cost of government insurance programs could significantly influence the purchase of healthcare services and products and may result in lower prices for our products or the exclusion of our products from reimbursement programs. In many foreign markets, pricing and profitability of medical devices are subject to government control. We are susceptible to changes in government-mandated coverage requirements and other controls which could impact access to and affordability of our products. In the United States, we expect that there will continue to be federal and state proposals for similar controls. As we continue to expand internationally, these government controls will have an increasing effect on our business and results of operations. Any of the above factors may have a material adverse effect on our ability to increase or maintain our revenue or otherwise have a material adverse impact on our business, financial condition, and results of operations.

In the United States and other countries, government and private sector access to health care products continues to be a subject of focus, and efforts to reduce health care costs are being made by third-party payors. Most of our customers rely on third-party payors, including government programs and private health insurance plans, to cover the cost of our products. We expect that these continuing cost reduction and containment measures may reduce the cost or utilization of our products and could lead to patients being unable to obtain approval for coverage or payment from these third-party payors or to costs being shifted to patients for our products. Additionally, as a result of the economic slowdown, some customers have lost access and others may lose access to their private health insurance plan if they lose their job, and an impact to job status may extend for a prolonged period of time, beyond possible coverage periods through COBRA, or where the cost to maintain coverage may not be affordable to our customers. As most of our customers currently rely on third-party payors, including government programs and private health insurance plans, to cover the cost of our products, our customers may lose coverage or reimbursement for our products, which may harm our business and results of operations. We have experienced, and anticipate that we will continue to experience, downward pressure on product pricing. To the extent these cost containment efforts are not offset by greater patient access to our products, our revenue may be reduced and our business may be harmed.

We have experienced, and anticipate that we will continue to experience, decreasing prices for our products due to pricing pressure from managed care organizations and other third-party payors, increased market power of payors, and increased competition among suppliers, including manufacturing services providers, as the medical device industry consolidates. If the prices for our products and services decrease and we are unable to reduce our expenses, including the cost of sourcing materials, logistics and the cost to manufacture our products, our business, results of operations, financial condition and cash flows will be adversely affected.

Our products are manufactured at certain facilities, with limited alternate facilities. If an event occurs at one of our facilities that results in damage to, restrictions on the use of, or closure of, one or more of such facilities, or if our distributions from those facilities are limited or restricted in any way, we may be unable to manufacture the relevant products at the previous levels or at all. Because of the time required to approve, lease, and build out a manufacturing facility, an alternate facility and/or a third-party may not be available on a timely basis to replace production capacity in the event manufacturing capacity is lost. Additionally, the majority of our operations are conducted at facilities located in San Diego, California, Mesa, Arizona, and Malaysia. We take precautions to safeguard our facilities, which include manufacturing protocols, insurance, health and safety protocols, and off-site storage of data. However, a natural or man-made disaster, such as fire, flood, earthquake, act of terrorism, cyber-attack or other disruptive event, such as a public health emergency, could cause substantial delays in our operations, damage, destroy or limit our manufacturing equipment, inventory, or records and cause us to incur additional expenses. Earthquakes are of particular significance since our manufacturing facilities in California are located in an earthquake-prone area. Wildfires are also increasingly more common in southern California and present risk to our manufacturing operations. Our Arizona facility may confront water supply issues resulting from the ongoing drought in the Western United States and our Malaysia facility may confront issues related to its construction on a reclaimed wetland and the political stability of the Malaysia government. In the event our existing manufacturing facilities or equipment are affected by man-made or natural disasters, we may be unable to manufacture products for sale or meet customer demands or sales projections. If our manufacturing operations were curtailed or ceased, it would seriously harm our business. The insurance we maintain against fires, floods, earthquakes and other natural disasters and similar events may not be adequate to cover our losses in any particular case. If we experience manufacturing difficulties or disruptions, it could result in insufficient inventory, increased costs, immediate shortages in product or component supply, and decreased sales, and our business could be harmed.

Our operations and performance depend on worldwide economic and political conditions. These conditions have been adversely impacted by continued global economic uncertainty, political instability and military hostilities in multiple geographies, monetary and financial uncertainties in Europe and other foreign countries, global health pandemics, rising interest rates, and domestic and global inflationary trends. These include potential reductions in the overall stability and suitability of the Euro as a single currency, given the economic and political challenges facing individual Eurozone countries. These conditions have made and may continue to make it difficult for our customers and potential customers to afford our products, and could cause our customers to stop using our products or to use them less frequently. If that were to occur, our revenue may decrease and our performance may be negatively impacted. In addition, the pressure on consumers to absorb more of their own health care costs has resulted in some cases in higher deductibles and limits on durable medical equipment, which may cause seasonality in purchasing patterns. Furthermore, during economic uncertainty, our customers have had job losses and may continue to have issues gaining timely access to sufficient health insurance or credit, which could result in their unwillingness to purchase products or impair their ability to make timely payments to us. A recession, depression or other sustained adverse market event could materially and adversely affect our business and the value of our common stock. We cannot predict the reoccurrence of any economic slowdown or the strength or sustainability of the economic recovery, worldwide, in the United States, or in our industry. These and other economic factors could have a material adverse effect on our business, financial condition and results of operations.
