ITEM 1A.  RISK FACTORS

An investment in our ordinary shares involves a high degree of risk. Investors and prospective investors should carefully consider all of the information in this Annual Report on Form 10-K, including the risks and uncertainties described below. Any of the following risks could have a material adverse effect on our business, prospects, financial condition and results of operations. In any such case, the trading price of our ordinary shares could decline, and you could lose all or part of your investment. In assessing these risks, you should also refer to the other information contained in this Annual Report on Form 10-K, including our consolidated financial statements and the related notes thereto.

Risks relating to our business and our Products

Our business and prospects depend heavily on Optune Gio, which is currently approved only for the treatment of GBM, Optune Lua, which is currently approved for the treatment of NSCLC and MPM in certain countries and Optune Pax, which is currently approved for the treatment of pancreatic cancer in the U.S. If we are unable to increase sales of our Products, obtain further regulatory approvals and commercialize our Products for the treatment of additional indications, or are significantly delayed or limited in doing so, our business and prospects will be materially harmed.

To date we have received FDA regulatory approval under the PMA pathway and certain approvals in other jurisdictions for the use of Optune Gio for the treatment of adult patients with newly diagnosed GBM when used together with certain forms of chemotherapy and for the treatment of adult patients with recurrent GBM as monotherapy. Optune Gio has a CE mark affixed for the treatment of GBM in the EU and Switzerland. Optune Lua is approved by the FDA under the PMA pathway for adults with metastatic NSCLC who have progressed on or after a platinum-based regimen, together with docetaxel or PD-1/PD-L1 inhibitors. We have also received FDA approval under the HDE pathway to market Optune Lua for unresectable, locally advanced or metastatic, MPM when used together with standard chemotherapies. Optune Lua is also CE Certified for NSCLC and MPM in the EU and Switzerland. In addition, we received regulatory approval for Optune Lua for the treatment of adult patients with unresectable advanced/recurrent NSCLC concurrent with PD-1/PD-L1 inhibitors following progression on or after a platinum-based regimen in Japan. Most recently, we have received FDA regulatory approval under the PMA pathway for the use of Optune Pax for the treatment of locally advanced pancreatic cancer. However, such approvals and maintaining the CE Certificates of Conformity, and related CE marking, of our Products, as applicable, do not guarantee future revenues for these indications. Further, until we receive FDA and analogous approval in other jurisdictions for the use of our Products for other indications (including for NSCLC and pancratic cancer pending obtaining widespread reimbursement agreements), almost all of our revenues will derive from sales and royalties from sales of Optune Gio for the treatment of newly diagnosed and recurrent GBM. The commercial success of our Products and our ability to generate and maintain revenues from the sale of our Products will depend on a number of factors, including:

• our ability to develop and obtain additional regulatory approvals and further commercialize our Products for additional indications;

• our ability to expand into new markets and future indications;

• the acceptance of our Products by patients and the healthcare community, including physicians and third-party payers (both private and governmental), as therapeutically effective and safe;

• the accomplishment of various scientific, engineering, clinical, regulatory and other goals, which we sometimes refer to as milestones, on our anticipated timeline;

• the relative cost, safety and efficacy of alternative therapies;

• our ability to obtain and maintain sufficient coverage or reimbursement by private and governmental third-party payers and to comply with applicable health care coverage laws and regulations;

• the ability of our third-party manufacturers to manufacture our Products in sufficient quantities with acceptable quality;

• our ability to provide marketing, distribution and customer support for our Products;

• the presence of competitive products in our active indications;

• results of future clinical studies relating to our Products or other competitor products for similar indications;

• compliance with applicable laws and regulatory requirements, in particular in the EU;

• the maintenance of our existing regulatory approvals; and

• the consequences of any reportable adverse events involving our Products.

In addition, the promotion of our Products is limited to approved indications, which vary by geography. The labelling for Optune Gio in the U.S. is limited in certain respects (for example, it is approved specifically for glioblastomas of the supratentorial region of the brain, is indicated for use in the treatment of newly diagnosed GBM only when used together with temozolomide, and limited to use by adults ages 22 and older), which may limit the number of patients to whom it is prescribed. Similarly, the labeling for Optune Lua also contains certain limitations that may adversely affect adoption. For NSCLC it is approved specifically for concurrent use with PD-1/PDL-1 inhibitors or docetaxel for adult patients with metastatic NSCLC who have progressed on or after platinum-based therapies in most countries, but not docetaxel in Japan. Similarly, the MPM indication in the U.S. includes the requirement in the United States (applicable to all HDE-approved devices) to display on all marketing materials that the efficacy of the Product has not been established, as well as a limitation for use by adults ages 22 and older, and the absence of phase 3 clinical data.

Our ability to generate future revenues will also depend on achieving regulatory approval of, and eventual commercialization of, our Products for additional indications and in additional geographies, which is not guaranteed. Our near-term prospects are substantially dependent on our ability to obtain regulatory approvals on the timetable we have anticipated, and thereafter to further successfully commercialize our Products for additional indications. Regulatory changes or actions in areas in which we operate or propose to operate may further affect our ability to obtain regulatory approvals on our anticipated timetable. If we are not able to receive such approvals, meet other anticipated milestones, or further commercialize our Products, or are significantly delayed or limited in doing so, our business and prospects will be materially harmed and we may need to reduce expenses by delaying, reducing or curtailing the development of our Products and we may need to raise additional capital to fund our operations, which we may not be able to obtain on favorable terms, if at all.

To date, we have generated only occasional and intermittent operating profits, and we have a history of incurring substantial operating losses.

We were founded in 2000 and have only occasionally and intermittently generated operating profits. We have otherwise had a history of and expect to continue incurring substantial operating losses. We anticipate continuing to incur significant costs associated with commercializing our Products for approved indications including product sales, marketing, manufacturing, and distribution expenses. We expect our research, development, and clinical study expenses to remain significant in connection with our ongoing activities and as additional indications enter late-stage clinical development and as we advance our product development. Our expenses could increase beyond expectations if, for example, we are required by the FDA, or other regulatory agencies or similar governing bodies, to change manufacturing processes for our Products or to perform clinical, nonclinical or other types of studies in addition to those that we currently anticipate. Our revenues are dependent, in part, upon the size of the markets in the jurisdictions in which we receive regulatory approval, the accepted price for our Products and the ability to obtain coverage for our Products and thereafter reimbursement at the accepted applicable price. If the number of addressable patients is not as significant as we estimate, the indications approved by regulatory authorities are narrower than we expect or the eligible population for treatment is narrowed by competition, regulatory approvals, physician choice or treatment guidelines, we may not generate significant revenues. If we are not able to generate significant revenues, we may never be sustainably profitable.

Our clinical studies could be delayed or otherwise adversely affected by many factors, including difficulties in enrolling patients.

Clinical testing can be costly and take many years, and the outcome is uncertain and susceptible to varying interpretations. Moreover, success in preclinical and early clinical studies does not ensure that large-scale studies will be successful or predict final results. Acceptable results in early studies may not be replicable in later studies. A number of companies in the oncology industry have suffered significant setbacks in advanced clinical studies, even after promising results in earlier studies. Negative or inconclusive results or adverse events or incidents during a clinical study could cause the clinical study to be redone or terminated. In addition, failure to appropriately construct clinical studies could result in high rates of adverse events or incidents, which could cause a clinical study to be suspended, redone or terminated. We may be unable to obtain reimbursement for our Products used in clinical trials

where our Products are already part of the approved standard of care. We may be unable to obtain other drugs or therapies that are to be used together with our Products in a given protocol, either due to supply issues, recall or the ability to obtain materials in an efficient or economically feasible manner. Our failure or the failure of third-party participants in our studies to comply with their obligations to follow protocols and/or legal requirements may also result in our inability to use the affected data in our submissions to regulatory authorities.

The timely completion of clinical studies depends, among other things, on our ability to enroll a sufficient number of patients who remain in the study until its conclusion. We may experience difficulties in patient enrollment in our clinical studies for a variety of reasons, including:

• the severity of the disease under investigation;

• the limited size and nature of the patient population;

• the patient eligibility criteria defined in our protocol and other clinical study protocols;

• standards of care may vary by geographic region, affecting whether our protocols may be valid in a given region;

• the nature of the study protocol, including the attractiveness of, or the discomforts and risks associated with, the treatments received by enrolled subjects;

• difficulties and delays in clinical studies that may occur as a result of economic, political, industry and environmental conditions outside of our control;

• the ability to obtain IRB approval at clinical study locations;

• clinicians’ and patients’ perceptions as to the potential advantages, disadvantages and side effects of our Products in relation to other available therapies, including any new drugs or treatments that may be approved for the indications we are pursuing;

• availability of other clinical studies that exclude use of our Products;

• the possibility or perception that enrolling in a Product’s clinical study may limit the patient’s ability to enroll in future clinical studies for other therapies due to protocol restrictions;

• the possibility or perception that our software is not secure enough to maintain patient privacy;

• patient referral practices of physicians;

• the ability to monitor patients adequately during and after treatment;

• the availability of appropriate clinical study investigators, support staff, drugs and other therapeutic supplies and proximity of patients to clinical sites;

• physicians’ or our ability to obtain and maintain patient consents; and

• the risk that patients enrolled in clinical studies will choose to withdraw from or otherwise not be able to complete a clinical study.

If we have difficulty enrolling and retaining a sufficient number or diversity of patients to conduct our clinical studies as planned, or encounter other difficulties, we may need to delay, terminate or modify ongoing or planned clinical studies, any of which would have an adverse effect on our business.

If we are unable to continue the development of an adequate sales and marketing organization or contract with third parties to assist us, we may not be able to successfully commercialize our Products for current and future indications.

To achieve commercial success for our Products, we must continue to compliantly develop and grow our sales and marketing organization and, as necessary, enter into sales and distribution relationships with third parties to market and sell our Products. Developing and managing a sales and marketing organization is a difficult, expensive and time consuming process. We may not be able to successfully develop adequate sales and marketing capabilities to achieve our growth objectives. We compete with other medical device, pharmaceutical and life sciences companies to recruit, hire, train and retain the sales and marketing personnel that we anticipate we will need, and the nature of

our Products may make it more difficult to compete for sales and marketing personnel. In addition, because our current Products require, and we anticipate our future Products will require, physician training and education, our sales and marketing organization may need to grow substantially as we expand our approved indications and markets. As a consequence, our expenses associated with building up and maintaining our sales force and marketing capabilities may be disproportionate to the revenues we may be able to generate on sales of our Products.

If we are unable to establish adequate sales and marketing capabilities or successful sales and distribution relationships, we may fail to realize the full revenue potential of our Products for current and future indications, and we may not be able to achieve the necessary growth in a cost-effective manner or realize a positive return on our investment. In our current and future sales and distribution agreements with other companies, we generally do not and may not have control over the resources or degree of effort that any of these third parties may devote to our Products, and if they fail to devote sufficient time and resources to the marketing of our Products, or if their performance is substandard, our revenues may be adversely affected.

The success of our business may be dependent on the actions of our collaborative partners.

Our global business strategy includes, in part, the consummation of collaborative arrangements with companies who will support the development and commercialization of our Products and technology. For example, we have exclusively licensed rights to commercialize our Products in the field of oncology in Greater China to Zai pursuant to an agreement that also establishes a development partnership for TTFields therapy in multiple solid tumor indications. Zai is responsible for the development and commercialization of our Products in Greater China at its sole cost with certain assistance from us. We have also entered into several clinical collaborations with third parties to test our Products and technology together with other products and technologies.

When we collaborate with a third party for development and commercialization of a Product in a particular territory, we can expect to relinquish some or all of the control over the future success of that Product to the third party in that territory. In addition, our collaborative partners may have the right to abandon research or development projects and terminate applicable agreements, including payment obligations, prior to or upon the expiration of the agreed-upon terms. We may not be successful in establishing or maintaining collaborative arrangements on acceptable terms or at all, collaborative partners may terminate funding before completion of projects, our Products may not achieve the criteria for milestone payments, our collaborative arrangements may not result in successful product commercialization, our Products may not receive acceptable pricing and we may not derive any revenue from such arrangements. Additionally, our collaborators may not perform their obligations as expected or in compliance with study protocols or applicable laws. Our collaborators may also be subject to additional risks in their particular territories, such as a lack of intellectual property protections and/or enforcement or the possibility of nationalization. Acts or omissions by collaborators may disqualify study data for use in regulatory submissions and/or create liability for us in the jurisdictions in which we operate. Any disagreements with collaborators, including disagreements over proprietary rights, contract interpretation or the preferred course of development or commercialization, might cause delays or termination of the research, development or commercialization of Products, might lead to additional responsibilities for us with respect to developing or commercializing Products, or might result in litigation or arbitration, any of which would be time-consuming and expensive. To the extent that we are not able to develop and maintain collaborative arrangements, we would need to devote substantial capital to undertake development and commercialization activities on our own in order to further expand our global reach, and we may be forced to limit the territories in which we commercialize our Products.

We may not be successful in achieving market acceptance of our Products by healthcare professionals, patients and/or third-party payers in the timeframes we anticipate, or at all, which could have a material adverse effect on our business, prospects, financial condition and results of operations.

Our business model is predicated on achieving market acceptance of our Products as a monotherapy or together with well-established cancer treatment modalities like surgery, radiation, pharmacological and immunologic therapies. We may not achieve market acceptance of our Products for current or future indications within the timeframes we have anticipated, or at all, for a number of different reasons, including the following factors:

• it may be difficult to gain or maintain broad acceptance of our Products because they are new technologies and involve a novel mechanism of action and, as such, physicians may be reluctant to prescribe our Products without prior experience or additional data or training;

• physicians may be reluctant to prescribe our Products due to their perception that the supporting clinical study designs have limitations, as they are, for example, unblinded, or because reimbursement for

physician time spent prescribing and assisting patients with our Products is low compared to other therapies;

• physicians at large academic universities and medical centers may prefer to enroll patients into clinical studies instead of prescribing our Products;

• it may be difficult to gain broad acceptance at community hospitals where the number of patients seeking treatment may be more limited than at larger medical centers, and such community hospitals may not be willing to invest in the resources necessary for their physicians to become trained to use our Products, which could lead to reluctance to prescribe our Products;

• patients may be reluctant to use our Products for various reasons, including a perception that the treatment is untested or difficult to use (for example, they will need to shave the areas on their bodies where the arrays are applied) or a perception that our software is not secure;

• our Products may have side effects (for example, dermatitis where the arrays are placed) and our Products cannot be worn in all circumstances (for example, they cannot get wet and are difficult to wear in high temperatures); and

• the price of our Products includes a monthly fee for use of the device and therefore, as the duration of the treatment course increases, the overall price will increase correspondingly and, when used together with other treatments, the overall cost of treatment will be greater than using a single type of treatment.

In particular, our Products may not achieve market acceptance for current or future indications because of the following additional factors:

• achieving patient acceptance could be difficult because we are targeting devastating diseases with poor prognoses, and not all patients with potentially short lifespans are willing to comply with requirements of treatment with our Products, such as the need to use our Products for a certain amount of time per day, carrying around a device and shaving the area where the arrays are worn, and other patients may forego our Products for financial, privacy, cosmetic, visibility or mobility reasons;

• achieving patient compliance is difficult because the recommended use of our currently marketed Products is throughout the day, requiring patients to wear the device nearly continuously, which to some extent restricts physical mobility because the battery must be frequently exchanged and recharged, and the patient or a caregiver must ensure that it remains continuously operable and this may also impact the pool of patients to whom physicians may be willing to prescribe our Products;

• certain patients are contraindicated to using our Products due to a variety of factors, including, but not limited to, those who have an active implanted medical device, those who have a skull defect, and those who are sensitive to the materials used in our Products;

• there are certain perceived limitations to our study designs or data obtained from our clinical studies;

• efficacy may also be limited in instances where patients take a break from the device, for example when experiencing skin rashes or while bathing or swimming (because our Products should not get wet); and

• patients may decline therapy or prescribers may be unwilling to prescribe our Products due to certain adverse events reported in clinical studies by patients treated with our Products as monotherapy include medical device site reaction, headache, malaise, muscle twitching, fall and skin ulcer; additional adverse events reported in clinical studies by patients treated with our Products when used together with chemotherapies in addition to the above, were thrombocytopenia, nausea, constipation, vomiting, fatigue and other side effects consistent with treatment with chemotherapies.

In addition, even if we are successful in achieving market acceptance of our Products for GBM, NSCLC, MPM or pancreatic cancer, we may be unsuccessful in achieving market acceptance of our Products for other indications, such as brain metastases from NSCLC and other solid tumor cancers, because certain radiation, chemotherapies and/or systemic medical therapies may become or remain the preferred standard of care for these indications.

There may be other factors that are presently unknown to us that also may negatively impact our ability to achieve market acceptance of our Products. If we do not achieve market acceptance of our Products in the timeframes we anticipate, or are unable to achieve market acceptance at all, our business, prospects, financial condition and results of operations could be materially adversely affected.

Failure to secure and maintain adequate coverage and reimbursement from third-party payers could adversely affect acceptance of our Products and reduce our revenues.

We expect that the vast majority of our revenues will come from third-party payers either directly to us in markets where we provide our Products or plan to provide our device candidates to patients or indirectly via payments made to hospitals or other entities providing our Products or which may in the future provide our device candidates to patients.

In the U.S., private payers cover the largest segment of the population, with the remainder either uninsured or covered by governmental payers. The majority of the third-party payers outside the U.S. are government agencies, government sponsored entities or other payers operating under significant regulatory requirements from national or regional governments.

Third-party payers may decline to cover and reimburse certain procedures, supplies or services. Additionally, some third-party payers may decline to cover and reimburse our Products for a particular patient even if the payer has a favorable coverage policy addressing our Products or previously approved reimbursement for our Products. Additionally, private and government payers may consider the cost of a treatment in approving coverage or in setting reimbursement for the treatment.

Private and government payers around the world are increasingly challenging the prices charged for medical products and services. Additionally, the containment of healthcare costs has become a priority of governments around the world. Adoption of additional price controls and cost-containment measures, and adoption of more restrictive policies in jurisdictions with existing controls and measures by both private and public payers, could further limit our revenues and operating results. If third-party payers do not consider our Products or the use of our Products together with additional treatments to be cost-justified under a required cost-testing model, they may not cover our Products for their populations or, if they do, the level of reimbursement may not be sufficient to allow us to sell our Products on a profitable basis.

Reimbursement for the treatment of patients with medical devices around the world is governed by complex mechanisms established on a national or sub-national level in each country. These mechanisms vary widely among countries, are sometimes informal and unpredictable, and evolve continuously, reflecting the efforts of these countries to reduce public spending on healthcare. As a result, obtaining and maintaining reimbursement for the treatment of patients with medical devices has become more challenging globally. We cannot guarantee that the use of our Products will receive reimbursement approvals and cannot guarantee that our existing reimbursement approvals will be maintained in any country.

We provide financial assistance to certain patients in certain markets who qualify based on established financial and other criteria. Primarily, we provide financial assistance to patients where we have or are actively pursuing coverage and reimbursement. This financial assistance is intended to defray out-of-pocket costs for our Products for patients who begin treatment but who are unable to pay for the costs of their treatment not covered by insurance. Our costs associated with this program could increase if payers increase the cost-sharing burden of patients or we do not obtain coverage and reimbursement and we elect to continue providing financial assistance in those markets.

Our failure to secure or maintain adequate coverage or reimbursement for our Products by third-party payers in the U.S. or in the other jurisdictions in which we market our Products could have a material adverse effect on our business, revenues and results of operations and cause our stock price to decline.

We may not be successful in securing and maintaining reimbursement codes necessary to facilitate accurate and timely billing for our Products or physician services attendant to our Products.

Third-party payers, healthcare systems, government agencies or other groups often issue reimbursement codes to facilitate billing for products and physician services used in the delivery of healthcare. Within the U.S., the billing codes most directly related to our Products are contained in the Healthcare Common Procedure Coding System ("HCPCS code set"). The HCPCS code set contains Level I codes that describe physician services, also known as Common Procedural Terminology codes ("CPT codes") and Level II codes that primarily describe products. CMS is responsible for issuing the HCPCS Level II codes. The American Medical Association issues HCPCS Level I codes.

We have secured unique HCPCS Level II codes that describe our Products and we are able to use these codes in the U.S. to bill third-party payers. Loss of these codes or any alteration in the reimbursement amounts attached to these codes would materially impact our operating results. We do not expect to obtain different codes for new indications.

Except for a Category III CPT code for TTFields therapy treatment planning services using our MAXPOINT mapping software, which does not include payment rates, no CPT codes specific to our therapy currently exist to describe physician services related to the delivery of therapy using our Products. Other CPT codes for physician services specifically related to our Products may not be obtainable. Our future revenues and results may be affected by the

absence of specific CPT codes, as physicians may be less likely to prescribe the therapy when there is no certainty that adequate reimbursement will be available for the time, effort, skill, practice expense and malpractice costs required to provide the therapy to patients. Coverage and payment relating to these codes is subject to discretion by each third-party payer.

Outside the U.S., Germany, France and Japan, we have not secured codes to describe our Products or to document physician services related to the delivery of therapy using our Products. The failure to obtain and maintain these codes could affect the future growth of our business.

There is no assurance that Medicare or the Medicare Administrative Contractors will provide, or continue to provide, coverage or adequate payment rates for our Products.

We anticipate that a significant portion of patients using our Products will be beneficiaries under the Medicare program in the U.S. Failure to secure or maintain coverage or maintain adequate reimbursement from Medicare would reduce our revenues and may also affect the coverage and reimbursement decisions of other third-party payers in the U.S. and elsewhere.

Medicare classifies our Products as durable medical equipment ("DME"). Medicare has the authority to issue national coverage determinations or to defer coverage decisions to its regional Medicare Administrative Contractors ("MACs"). The fact that only two MACs administer the entire DME program may negatively affect our ability to petition individual medical policy decision-makers at the MACs for coverage. The absence of a positive coverage determination or a future restriction to existing coverage from Medicare or the DME MACs would materially affect our future revenues.

Additionally, Medicare has the authority to publish the reimbursement amounts for DME products. Medicare has published a reimbursement amount for Optune Gio that falls below the median reimbursement that we have established with non-Medicare payers. Medicare may in the future publish reimbursement amounts for our Products that do not reflect then-current prices for our Products or Medicare may decrease existing reimbursement amounts published for our Products. Medicare fee schedules are frequently referenced by private payers in the U.S. and around the world. Medicare's publication of reimbursement amounts for our Products that are below our Products’ established prices could materially reduce our revenues and operating results with respect to non-Medicare payers in the U.S. and our other active markets.

Medicare has assigned the billing codes describing our Products to the DME category for products that require frequent and substantial servicing. DME items in this billing category are billed monthly and payment is not capped after a time period. If Medicare revises its payment category classifications for our Products, this action could materially reduce our revenues and operating results.

CMS requires prior authorization for certain DME items. Claims for such items that did not receive prior authorization before they were furnished to a beneficiary will be automatically denied. In the event Medicare adds one of our Products to the list of items requiring prior authorization, our ability to bill and secure reimbursement for patients who would otherwise be covered to use our Product under the Medicare fee-for-service program may be reduced.

Medicare denied coverage for all claims prior to the September 1, 2019 effective date of DME MAC LCD L34823, which provides coverage for Optune Gio for the treatment of newly diagnosed GBM subject to certain conditions and restrictions. We expect that Medicare will continue to deny essentially all claims that do not meet the coverage policy terms. Although we are actively appealing these coverage denials, we are prohibited from balance billing most of our existing Medicare fee-for-service patients for amounts not paid by Medicare. Therefore, we are absorbing and may continue to absorb the costs of treatment for amounts not paid by Medicare.

We appeal Medicare coverage denials through the Medicare appeals process: redetermination by a MAC, reconsideration by a Qualified Independent Contractor, hearing before an Administrative Law Judge (“ALJ”) at the Office of Medicare Hearings and Appeals, review by the Medicare Appeals Council, and judicial review in U.S. District Court. We cannot provide any assurance that our outstanding ALJ appeals will be favorably decided. Further, we anticipate that, even if we are successful in winning our appeals, we will experience a significant delay in securing reimbursement for Medicare patients when Medicare’s DME MACs deny coverage for patients who start therapy.

While we have obtained Medicare coverage for Optune Gio, we cannot provide any assurance that we can access transitional, expedited, or expanded Medicare coverage for our future Products, including Optune Lua for NSCLC or Optune Pax for pancreatic cancer. CMS has issued new guidance regarding coverage of emerging technologies that is limited in nature and unlikely to provide a faster pathway to coverage for our future Products.

We depend on single-source suppliers for some of our components. The loss of these suppliers could prevent or delay shipments of our Products, delay our clinical studies or otherwise adversely affect our business.

In certain jurisdictions, we source some of the components of our Products from only a single vendor or manufacturer. If any one of these single-source suppliers were to fail to continue to provide components to us on a timely basis, or at all, our business and reputation could be harmed. Our policy is to seek and maintain second-source suppliers when economically feasible, but we can provide no assurance that we will secure or maintain such suppliers. We have developed or are in the process of developing and obtaining regulatory approval for second sources for components in all jurisdictions where economically feasible. Various steps must be taken before securing these suppliers, including qualifying these suppliers in accordance with regulatory requirements, but we may never receive such approvals. The risks associated with the failure of our suppliers to comply with strictly enforced regulatory requirements as described below are exacerbated by our dependence on single-source suppliers.

If we experience any deficiency in the quality of, delay in or loss of availability of any components supplied to or manufactured for us by third-party suppliers, or if we switch suppliers or components, we may face additional regulatory delays and the manufacture and delivery of our Products would be interrupted for an extended period of time, which could materially adversely affect our business, prospects, financial condition and results of operations. If we are required to obtain prior regulatory approval from the FDA or regulatory authorities or similar governing bodies in other jurisdictions or to conduct a new conformity assessment procedure and obtain new CE Certificates of Conformity in the EU to use different suppliers or components for our Products, regulatory approval or the CE Certificates of Conformity for our Products may not be received on a timely basis, or at all, which would have a material adverse effect on our business, prospects, financial condition and results of operations.

Quality control problems with respect to devices and components supplied by third-party suppliers could have a material adverse effect on our reputation, our clinical studies or the commercialization of our Products and, as a result, a material adverse effect on our business, prospects, financial condition and results of operations .

Our Products, which are manufactured by third parties, are highly technical and are required to meet exacting specifications. Any quality control problems that we experience with respect to the devices and components supplied by third-party suppliers could have a material adverse effect on our reputation, our attempts to complete our clinical studies, our operating expenses or the commercialization of our Products. The failure of our suppliers to comply with strictly enforced regulatory requirements could expose us to regulatory action, including warning letters, product recalls, suspension or termination of distribution, product seizures or civil penalties. If we experience any delay in the receipt or deficiency in the quality of products supplied to us by third-party suppliers, or if we have to switch to replacement suppliers, we may face additional regulatory delays and the manufacture and delivery of our Products would be interrupted for an extended period of time, which would materially adversely affect our business, prospects, financial condition and results of operations.

If the third parties on which we rely to conduct our preclinical and clinical studies and to assist us with research and development do not perform as contractually required or expected, we may not be able to obtain regulatory approvals for or commercialize our Products.

We do not have the ability to independently conduct certain of our preclinical and development activities or any of our clinical studies for our Products; therefore, we must rely on third parties, such as contract research organizations, medical institutions, clinical investigators, contract laboratories and collaborative partners, to conduct such studies. We and these third parties are required to comply with current good clinical practices ("cGCPs"), which are regulations and guidelines enforced by the FDA under the medical device Quality System Regulation ("QSR") and comparable regulatory authorities in other jurisdictions for clinical development. We and these third parties are also required to comply with current good laboratory practices ("cGLPs"), which are regulations and guidelines enforced by the FDA and comparable regulatory authorities in other jurisdictions for nonclinical laboratory studies. If we or any of these third parties fail to comply with applicable cGLP and cGCP regulations, the data generated in our nonclinical studies and clinical studies may be deemed unreliable and the FDA or regulatory authorities in other jurisdictions may require us to perform additional nonclinical or clinical studies before approving our applications. We cannot be certain that, upon inspection or review of our data, such regulatory authorities will determine that any of our nonclinical studies or clinical studies comply with the applicable cGLP or cGCP regulations.

Additionally, any third parties conducting our preclinical, clinical and other development programs are not and will not be our employees and, except for remedies available to us under our agreements with such third parties, we cannot control whether or not they devote sufficient time and resources to our ongoing preclinical, clinical and other development programs. If these third parties do not successfully carry out their contractual duties or regulatory obligations or meet expected deadlines, if these third parties need to be replaced or if the quality or accuracy of the data they obtain is compromised due to the failure to adhere to our clinical protocols or regulatory requirements or for other reasons, our development activities or clinical studies may be extended, delayed, suspended or terminated, and we may not be able to obtain regulatory approval for our Products or successfully commercialize our Products on a timely basis, if at all, and our business, prospects and results of operations may be adversely affected.

Continued testing of our Products may not yield successful results and could reveal currently unknown aspects or safety hazards associated with our Products.

Our research and development programs are designed to test the safety and efficacy of our Products and TTFields through extensive preclinical and clinical testing. Even if our ongoing and future preclinical and clinical studies are completed as planned, we cannot be certain that their results will support our claims or that the FDA and other regulatory authorities will agree with our conclusions. Success in preclinical studies and early clinical studies does not ensure that later clinical studies will be successful, and we cannot be sure that the later studies will replicate the results of prior studies and preclinical studies. The clinical study process may fail to demonstrate that our device candidates are safe and effective for the proposed indicated uses, which could cause us to abandon a device candidate and may delay development of others. It is also possible that patients enrolled in clinical studies will experience adverse side effects that have not been previously observed. In addition, our preclinical and clinical studies for our device candidates involve a relatively small patient population and, as a result, these studies may not be indicative of future results.

We may experience numerous unforeseen events during, or as a result of, the testing process that could delay or prevent further commercialization of our Products, including the following:

• Preclinical and clinical testing for our Products may not produce the desired effect, may be inconclusive or may not be predictive of safety or efficacy results obtained in future clinical studies, following long-term use or in much larger populations;

• unanticipated adverse events or other side effects that are not currently known may occur during our clinical studies that may preclude additional regulatory approval or result in additional limitations to commercial use if approved; and

• the data collected from our clinical studies may not reach statistical significance or otherwise not be sufficient to support FDA or other regulatory approval.

If unacceptable side effects arise in the development of our Products for future indications, we could suspend or terminate our clinical studies or the FDA or other regulatory authorities could order us to cease clinical studies or deny approval of our device candidates for any or all targeted indications, narrow the approved indications for use or otherwise require restrictive product labeling or marketing or require further clinical studies, which may be time-consuming and expensive and may not produce results supporting FDA or other regulatory approval of our Products in a specific indication. Treatment-related side effects could also affect patient recruitment or the ability of enrolled patients to complete the study or result in potential product liability claims. In addition, these side effects may not be appropriately recognized or managed by the treating medical staff. We expect to have a need to train medical personnel using our device candidates to understand the side effect profiles for our clinical studies and upon any commercialization of our Products for future indications. Inadequate training in recognizing or managing the potential side effects of our Products could result in patient injury or death. Any of these occurrences may harm our business, prospects and financial condition significantly.

Any delay or termination of our clinical studies will delay the filing of submissions for regulatory approvals of our Products and ultimately our ability to commercialize our Products and generate revenues. Furthermore, we may abandon our Products for indications that we previously believed to be promising. Over time, we expect to make modifications to our Products that are designed to improve efficacy, reduce side effects, enhance the user experience and other purposes. It is possible that our patients will not accept these developments or see them as improvements, necessitating abandoning the development or spending additional development efforts to refine the modification. Any of these events could have a material adverse effect on our business, prospects, financial condition and results of operations and cause our stock price to decline.

We face competition from numerous competitors, which may make it more difficult for us to achieve significant market penetration and which may allow our competitors to develop additional oncology treatments to compete with our Products.

The oncology market is intensely competitive, subject to rapid change and significantly affected by new product introductions and other market activities of industry participants. Our Products primarily compete with radiation and pharmacological therapies. We may face additional competition as advancements are made in the field of anti-cancer therapies and as we enter additional oncological markets. To date, we have conducted clinical studies where our Products are used together with a certain subset of other anti-cancer therapies. Many of our competitors are large, well-capitalized companies with significantly greater market share and resources than we have. As a consequence, they are able to spend more aggressively on product development, marketing, sales and other initiatives than we can. Many of these competitors could have:

• significantly greater name recognition and experience;

• established distribution networks and/or relationships with government agencies, healthcare professionals, patients and third-party payers;

• additional product lines, and the ability to offer rebates or bundle products to offer higher discounts or more competitive pricing or other incentives to gain a competitive advantage; and

• greater financial and human resources for research and development, sales and marketing, patent litigation and/or acquisitions.

Although we believe our Products represent a treatment modality that can be used together with other cancer treatment modalities, our current and future competitors may at any time develop additional drugs, biologics or devices for the treatment of GBM, NSCLC, MPM, pancreatic cancer or other solid tumors that could be more effective from a therapeutic or cost-basis perspective than using our Products. In our currently-approved indications, if current or future competitors develop a product that proves to be superior or comparable to our Products, our revenues may decline. In addition, some of our competitors may compete by lowering the price of their cancer treatments. If these competitors’ products were to gain acceptance by healthcare professionals, patients or third-party payers, a downward pressure on prices could result. If prices were to fall, we may not be able to improve our gross margins or sales growth sufficiently to be sustainably profitable. For future indications, other companies could view us as a competitor and attempt to block our market entry or otherwise hinder our Product growth in a market. We are aware of third parties in the United States and China developing devices and filing for intellectual property protection related to TTFields and similar technologies, which, if approved, may directly compete with our Products. Competitors could also pursue lawsuits to invalidate our patents or develop alternative technologies for the application of TTFields into a patient that we did not foresee or protect.

As we expand, we may experience difficulties managing our growth.

Our anticipated growth will place a significant strain on our management and on our operational and financial resources and systems. We could face challenges inherent in efficiently managing a more complex business with an increased number of employees over large geographic distances, including the need to implement appropriate systems, policies, benefits and compliance programs. Failure to manage our growth effectively could materially adversely affect our business. Additionally, our anticipated growth will increase the demands placed on our third-party suppliers, resulting in an increased need to carefully monitor the available supply of components and services and to scale up our quality assurance programs. There is no guarantee that our suppliers will be able to support our anticipated growth. Any failure by us to manage our growth effectively could have an adverse effect on our ability to achieve our development and commercialization goals.

Because of the specialized nature of our business, the termination of relationships with our key employees, consultants and advisors may prevent us from successfully operating our business, including developing our Products, conducting clinical studies, commercializing our Products and obtaining any necessary financing.

We are highly dependent on the members of our executive team, the loss of whose services may adversely impact the achievement of our objectives. While we have entered into employment agreements with each of our key executives, any of them could leave our employment at any time. We do not have "key person" insurance on any of our employees. The loss of the services of one or more of our current employees might impede the achievement of our business objectives.

The competition for qualified personnel in the oncology and medical device fields is intense, and we rely heavily on our ability to attract and retain qualified scientific, regulatory, technical and managerial personnel. Our future success depends upon our ability to attract, retain and motivate highly skilled employees. In order to commercialize our Products successfully, we will be required to expand our workforce, particularly in the areas of research and development and clinical studies, regulatory affairs, sales and marketing and supply chain management. These activities will require the addition of new personnel and the development of additional expertise by existing management personnel. We face intense competition for qualified individuals from numerous pharmaceutical, biopharmaceutical and biotechnology companies, as well as academic and other research institutions. We may not be able to attract and retain these individuals on acceptable terms or at all. Failure to do so could materially harm our business.

Product liability suits, whether or not meritorious, could be brought against us due to alleged defective devices or for the misuse of our Products, which could result in expensive and time-consuming litigation, payment of substantial damages and/or expenses and an increase in our insurance rates.

If our current or future devices are defectively designed or manufactured, contain defective components or are misused, or if someone claims any of the foregoing, whether or not meritorious, we may become subject to substantial and costly litigation. For example, we may be sued if our Products cause or are perceived to cause injury or are found to be otherwise unsuitable during clinical testing, manufacturing, marketing or sale. This may occur if our Products are misused or damaged, have a sudden failure or malfunction (including with respect to safety features) or are otherwise impaired due to wear and tear. Even absent a product liability suit, malfunctions of our Products or misuse by physicians or patients would need to be remedied swiftly in order to maintain continuous use and ensure efficacy of our Products.

Any product liability claims may include allegations of defects in manufacturing, defects in design, a failure to warn of dangers inherent in the device, negligence, strict liability or a breach of warranties. Claims could also be asserted under state consumer protection acts. If we cannot successfully defend ourselves against product liability claims, we may incur substantial liabilities or be required to limit commercialization of our Products. Even successful defense may require significant financial and management resources. Regardless of the merits or eventual outcome, liability claims may result in:

• decreased demand for our Products;

• injury to our reputation;

• withdrawal of clinical study participants and inability to continue clinical studies;

• initiation of investigations by regulators;

• costs to prepare for and defend the related litigation;

• a diversion of management’s time and our resources;

• substantial monetary awards to study participants or patients;

• product recalls, withdrawals or labeling, marketing or promotional restrictions;

• loss of revenues;

• exhaustion of any available insurance and our capital resources;

• the inability to commercialize any device candidate; and

• a decline in our share price.

Product liability claims could divert management’s attention from our core business, be expensive to defend and result in sizable damage awards against us. We may not have sufficient insurance coverage for all claims. Any product liability claims brought against us, with or without merit, could increase our product liability insurance rates or prevent us from securing continuing coverage, could harm our reputation in the industry and could reduce revenues. Product liability claims in excess of our insurance coverage would be paid out of cash reserves, if any, which could have a material adverse effect on our business, prospects, financial condition and results of operations and cause our stock price to decline. Even if our agreements with our third-party manufacturers and suppliers entitle us to indemnification against losses, such indemnification may not be available or adequate should any claim arise.

Other future litigation and regulatory actions could have a material adverse impact on the Company.

From time to time, we may be subject to litigation and other legal and regulatory proceedings relating to our business or investigations or other actions by governmental agencies, including as described in Part I, Item 3 "Legal Proceedings" of this Annual Report on Form 10-K. No assurances can be given that the results of these or new matters will be favorable to us. An adverse resolution of lawsuits, arbitrations, investigations or other proceedings or actions could have a material adverse effect on our financial condition and results of operations, including as a result of non-monetary remedies. Defending ourselves in these matters may be time-consuming, expensive and disruptive to normal business operations and may result in significant expense and a diversion of management’s time and attention from the operation of our business, which could impede our ability to achieve our business objectives. Additionally, any amount that we may be required to pay to satisfy a judgment, settlement, fine or penalty may not be covered by insurance. Subject to the Jersey Companies Law, our articles of association permit us to indemnify any director against any liability, to purchase and maintain insurance against any liability for any director and to provide any director with funds (whether by loan or otherwise) to meet expenditures incurred or to be incurred by such director in defending any criminal, regulatory or civil proceedings or in connection with an application for relief (or to enable any such director to avoid incurring such expenditure). In addition, we have entered into indemnification agreements with each of our directors and officers to indemnify them against certain liabilities and expenses arising from their being a director or officer to the maximum extent permitted by Jersey law. In the event we are required to make such payments to our directors and officers, there can be no assurance that any of these payments will not be material.

Global economic, political, industry and environmental conditions constantly change and unfavorable conditions may have a material adverse effect on our business and results of operations.

We are a global company with worldwide operations. Volatile economic, political and market conditions, such as political or economic instability, civil unrest, trade sanctions, majority hostilities or acts of terrorism in the regions in which we operate may have a negative impact on our operating results and our ability to achieve our business objectives. We may not have insight into economic and political trends that could emerge and negatively affect our business. In addition, significant or volatile changes in interest rates or exchange rates between the U.S. dollar and other currencies may have a material adverse impact upon our liquidity, revenues, costs and operating results.

In particular, we have research facilities located in Israel, and certain key suppliers manufacture their goods in Israel. Due to the high-conflict nature of this area, Israel is subject to additional political, economic and military confines, which could result in a material adverse effect on our operations. Parties with whom we do business have sometimes declined to travel to Israel during periods of heightened unrest or tension, forcing us to make alternative arrangements when necessary. In addition, the political and security situation in Israel may result in parties with whom we have agreements involving performance in Israel being unable perform their obligations, due to transportation and other disruptions, and/or claiming that they are not obligated to perform their commitments under those agreements pursuant to force majeure provisions in the agreements.

Additionally, natural disasters and public health emergencies, such as extreme weather events and pandemics, such as seen with COVID-19, could have a significant adverse effect on our business, including interruption of our commercial and clinical operations, supply chain disruption, endangerment of our personnel, fewer prescriptions written, fewer patient visits, increased patient drop-out rates, delays in recruitment of new patients, and other delays or losses of materials and results.

We are increasingly dependent on information technology systems and subject to privacy and security laws. Our Products and our systems and infrastructure face certain risks, including from cyber security breaches and data leakage.

We increasingly rely upon technology systems and infrastructure. Our technology systems, including our Products, are potentially vulnerable to breakdown or other interruption by fire, power loss, system malfunction, unauthorized access and other events. Likewise, data privacy breaches by employees and others with both permitted and unauthorized access to our Products and our systems may pose a risk that protected patient information ("PI") may be exposed to unauthorized persons or to the public, or may be permanently lost. The increasing use and evolution of technology, including cloud-based computing, creates additional opportunities for the unintentional dissemination of information, intentional destruction of confidential information stored in our systems or in non-encrypted portable media or storage devices. We could also experience a business interruption, information theft of confidential information, or reputational damage from industrial espionage attacks, malware or other cyber incidents, which may compromise our system infrastructure or lead to data leakage, either internally or at our third-party service providers or other business partners.

The size and complexity of our computer systems, and scope of our geographic reach, make us potentially vulnerable to information technology system breakdowns, internal and external malicious intrusion, cyberattacks and computer viruses. Because the techniques used to obtain unauthorized access, or to sabotage systems, change frequently and generally are not recognized until launched against a target, we may be unable to anticipate these techniques or to implement adequate preventative measures. If we do not allocate and effectively manage the resources necessary to build and sustain the proper technology infrastructure or properly manage third-party contractors who perform data management services on our behalf, then a security breach could subject us to, among other things, transaction errors, business process inefficiencies, the loss of customers, damage to our reputation, business disruptions or the loss of or damage to intellectual property. Such security breaches could expose us to a risk of loss of information, litigation, penalties, remediation costs and potentially significant liability to customers, employees, business partners and regulatory authorities, including, for example, under the Health Insurance Portability and Accountability Act of 1996 (“HIPAA”) in the United States and Regulation 2016/679 on the protection of natural persons with regard to the processing of personal data and on the free movement of such data under GDPR in the EU. If our data management systems (including third party data management systems) do not effectively collect, secure, store, process and report relevant data for the operation of our business, whether due to equipment malfunction or constraints, software deficiencies, or human error, our ability to effectively plan, forecast and execute our business plan and comply with applicable laws and regulations will be impaired. Any such impairment could materially and adversely affect our financial condition and results of operations.

While we have invested heavily in the protection of data and information technology and in related training, there can be no assurance that our efforts will prevent significant breakdowns, breaches in our systems or other cyber incidents or ensure compliance with all applicable security and privacy laws, regulations and standards, including with respect to third-party service providers that utilize sensitive personal information, including PI, on our behalf.

A security breach, whether of our Products, systems or third-party hosting services we utilize, could disrupt treatments being provided by our Products, disrupt access to our customers’ stored information, such as patient treatment data and health information, and could lead to the loss of, damage to or public disclosure of such data and information, including patient health information. Such an event could have serious negative consequences, including possible patient injury, regulatory action, fines, penalties and damages, reduced demand for our Products, an unwillingness of customers to use our Products, harm to our reputation and brand and time-consuming and expensive litigation, any of which could have a material adverse effect on our financial results. We carry a limited amount of insurance for cybersecurity liability, and our insurance coverage may be inadequate. In the future, our insurance coverage may be expensive or not be available on acceptable terms or in sufficient amounts, if at all.

Risks relating to the regulation of our business

Our device candidates must undergo rigorous preclinical and clinical testing and we must obtain regulatory approvals, which could be costly and time-consuming and subject us to unanticipated delays or prevent us from marketing any devices.

Our research and development activities, as well as the manufacturing and marketing of our Products, are subject to regulation, including regulation for safety, efficacy and quality, by the FDA in the U.S. In the EU member states where we market our Products and operate, we are subject to, inter alia, the Medical Device Regulation ("MDR"), which applies directly in all EU member states. In Switzerland, our Products and operations are subject to, inter alia, the Medical Devices Ordinance, which implements the MDR into Swiss law. In the United Kingdom, our Products and operation are subject to, inter alia, the Medical Devices Regulations 2002 and the Medical Devices (Amendment etc.) (EU Exit) Regulations 2020 (the "UK Regulations"), which implements the MDR and MDR like provisions into UK law. In Japan, we must obtain approvals from the Ministry of Health, Labour, and Welfare ("MHLW") to market our devices. We are regulated by comparable authorities in other countries. Regulations promulgated by the regulatory authorities in our applicable jurisdictions are wide-ranging and govern, among other things:

• the conduct of preclinical and clinical studies;

• product design, development, manufacturing, testing, storage and shipping;

• product labeling, advertising and promotion;

• regulatory jurisdiction, premarket clearance, approval and conformity assessment pathways and procedures for initial approvals, as well as for modifications introduced in marketed products;

• post-market surveillance and monitoring;

• reporting of adverse events or incidents and implementation of corrective actions, including product recalls;

• interactions with healthcare professionals and patients; and

• product sales and distribution.

We cannot be certain if or when the FDA, comparable regulatory agencies in other jurisdictions or our notified body might request additional or modified studies on our Products, under what conditions such studies might be requested, or the required size or length of any such studies. The data collected from our clinical studies may not be sufficient to support regulatory approval in the U.S., Japan and other countries or to obtain a CE Certificate in the EU for our various future device candidates. Even if we believe the data collected from our clinical studies are sufficient, the FDA and comparable regulatory bodies in other jurisdictions have substantial discretion in the assessment and approval or conformity assessment processes and may disagree with our interpretation of the data. Our failure to adequately demonstrate the safety and efficacy of any of our device candidates would delay or prevent regulatory approval in the U.S., Japan and other countries or delay or prevent a CE Certificate in the EU (and therefore be unable to affix the CE mark) for our device candidates, which could prevent us from being sustainably profitable. In addition, any change in the laws or regulations that govern the clearance and approval processes relating to our current and future devices could make it more difficult and costly to obtain clearance or approval for new devices, or to produce, market and distribute our Products. Delays in receiving clearance or approval may result from these factors and others outside of our control, such as implementation of significant new or revised laws, regulations and policies, reductions in budgets to these agencies, staffing cuts and shifting priorities within these agencies. Significant delays in receiving clearance or approval, or the failure to receive clearance or approval for our new devices would have an adverse effect on our ability to expand our business.

We intend to market our Products in a number of international markets in addition to our current markets. In order to market our Products in any jurisdiction and for other indications or purposes, we may be required to obtain separate regulatory approvals or CE Certificates for our Products, as applicable. The requirements governing the conduct of clinical studies and manufacturing and marketing of our device candidates outside the U.S. vary widely from country to country. CE Certificates and regulatory approvals in other jurisdictions may take longer to obtain than FDA approvals and can require, among other things, additional testing and different clinical study designs. CE Certification processes and regulatory approvals in other jurisdictions include essentially all of the risks associated with the FDA approval processes. Some regulatory agencies in other jurisdictions must also approve prices of our Products. Approval of a Product by the FDA does not guarantee approval of the same product by the health authorities of other countries or CE marking of our Products in the EU and vice versa. In addition, changes in regulatory policy in the U.S. or in other countries for the approval or CE marking of a medical device during the period of product development and regulatory agency review or notified body review of each submitted new application may cause delays or rejections.

In the European Economic Area (“EEA”), we are required to obtain a CE Certificate and to affix a CE mark to our Products. In the EEA, our devices must be subject to conformity assessment procedure involving an EEA notified body, a private organization accredited by an EEA member state to conduct conformity assessment procedures under the MDR. The notified body typically audits and examines the device’s technical documentation, including the clinical evaluation, and the quality system for the manufacture, design and final inspection of our devices before issuing a CE Certificate demonstrating compliance with the relevant requirements or the quality system requirements laid down in the relevant Annexes to the MDR. The MDR became active on May 26, 2021 and replaced Council Directive 93/42/EEC concerning medical devices (“MDD”) with transitional provisions for "legacy" devices under the MDD. The MDR introduced significant changes to the regulatory framework for medical devices in the EU, including new, stricter requirements that we must comply with in order to obtain CE Certificates for new product candidates, and to renew the CE Certificates for our "legacy" MDD-Products when they expire or by December 31, 2027 or 2028, depending on device class, whichever occurs first. These changes may prevent or delay the CE Certification of our device candidates or impact our ability to modify our Products on a timely basis. In particular, the delay in the publication of key MDR guidance documents at EU level and the limited availability of qualified notified bodies might affect our ability to timely comply and demonstrate such compliance with the new requirements or delay the MDR CE Certification of our device candidates. Further, as a result of the implementation of the MDR, our notified body (as well as many other notified bodies throughout the EEA) has suffered a significant backlog in issuing CE Certificate renewals. In the UK, our Products are regulated under the UK Regulations. There can be no assurance that the UK Regulations will be interpreted by UK regulators in the same manner as the MDR from which the UK Regulations are based, which may prevent or delay the UK CE certification of our device candidates or impact our ability to modify our Products on a timely basis.

We may choose to, or may be required to, suspend, repeat or terminate our clinical studies if they are not conducted in accordance with regulatory requirements, the results are negative or inconclusive or the studies are not well designed.

Clinical studies must be conducted in accordance with the FDA’s cGCPs and the equivalent laws and regulations applicable in other jurisdictions in which the clinical studies are conducted. The clinical studies are subject to oversight by the FDA, regulatory agencies in other jurisdictions, ethics committees and institutional review boards at the medical institutions where the clinical studies are conducted. In addition, clinical studies must be conducted with device candidates produced under the FDA’s QSR and in accordance with the applicable regulatory requirements in the other jurisdictions in which the clinical studies are conducted. The conduct of clinical studies may require large numbers of test patients.

The FDA or regulatory agencies in other jurisdictions might delay or terminate our clinical studies of a device candidate for various reasons, including:

• the device candidate may have unforeseen adverse side effects or may not appear to be more effective than current therapies;

• we may not agree with the FDA, a regulatory authority in another jurisdiction or an ethics committee regarding the protocol for the conduct of a clinical study;

• new therapies may become the standard of care while we are conducting our clinical studies, which may require us to revise or amend our clinical study protocols or terminate a clinical study; or

• fatalities may occur during a clinical study due to medical problems that may or may not be related to clinical study treatments.

Furthermore, the process of obtaining and maintaining regulatory approvals in the U.S. and other jurisdictions and CE Certification in the EU for new therapeutic products is lengthy, expensive and uncertain. It can vary substantially, based on the type, complexity and novelty of the product involved. Accordingly, any of our device candidates could take a significantly longer time than we expect to, or may never, gain regulatory approval or obtain CE Certification in the EU, which could have a material adverse effect on our business, prospects, financial condition and results of operations and cause our stock price to decline.

The process of obtaining and maintaining regulatory approvals may be further complicated when we seek approval for indications involving the use of our products together with pharmacological/immunological therapies and therapy candidates. If our regulators determine that the predominant questions stem from the pharmacological/immunological therapy in the study, they may require us and our partners to conduct the study under trial rules and regulations governing pharmacological/immunological therapies, which may differ significantly from medical device requirements. Adhering to pharmacological/immunological regulations and requirements governing clinical trials could make it more difficult to enroll study sites and patients, increase compliance costs and lengthen the time it takes to complete the study.

Legislative and regulatory changes in the U.S. and in other countries regarding healthcare insurance and government-sponsored reimbursement programs (such as Medicare in the United States) may adversely affect our business and financial results.

We rely to a material degree on highly regulated private and government-run health insurance programs for our revenue in most of the countries in which we operate. The laws and regulations regarding health care programs, both public and private, are driven by public policy considerations that may be unrelated to the direct provision of patient care, such as lowering costs or requiring or limiting access to healthcare options. These laws and regulations are very complicated and there are many requirements we must satisfy in order for our Products to become and remain eligible for reimbursement under these programs. In many cases we may have limited negotiating power when negotiating reimbursement rates for our Products.

In the future, lawmakers and regulators could also pass additional healthcare laws and implement other regulatory changes at both the national and local levels. These laws and regulations could potentially affect coverage and reimbursement for our Products. However, we cannot predict the ultimate content, timing or effect of any future healthcare initiatives or the impact any future legislation or regulation will have on us.

Governmental authorities in the U.S., EU member states, the UK, Switzerland, Israel, Japan, and other jurisdictions are increasingly active in their goal of reducing public spending on healthcare. We cannot, therefore, guarantee that the treatment of patients with our Products would be reimbursed in any particular country or, if successfully included on reimbursement lists, whether we will remain on such lists at a reasonable price.

We are subject to extensive post-marketing regulation by the FDA and comparable authorities in other jurisdictions, which could impact the sales and marketing of our Products and could cause us to incur significant costs to maintain compliance. In addition, we may become subject to additional regulation in other jurisdictions as we increase our efforts to market and sell current and future Products outside of the U.S.

We market and sell our Products, and expect to market and sell future Products, subject to extensive regulation by the FDA and numerous other federal, state and governmental authorities in other jurisdictions. These regulations are broad and relate to, among other things, the conduct of preclinical and clinical studies, product design, development, manufacturing, labeling, testing, product storage and shipping, premarket clearance and approval, conformity assessment procedures, premarket clearance and approval of modifications introduced in marketed products, post-market surveillance and monitoring, reporting of adverse events and incidents, pricing and reimbursement, interactions with healthcare professionals, interactions with patients, information security, advertising and promotion and product sales and distribution. Although we have received FDA approval to market our Products for specific indications together with specific other therapies, such as temozolomide for GBM and PD-1/PD-L1 inhibitors for NSCLC, we will require additional FDA approval to market our Products for other indications. We may be required to obtain approval of a new PMA, HDE or PMA/HDE supplement application for modifications made to our Products. This approval process is costly and uncertain, and it could take one to three years, or longer, from the time the application is filed with the FDA. We may make modifications in the future that we believe do not or will not require additional approvals, such as the introduction of software products that we have assessed as not subject to FDA regulation and that are intended for use by users of our Products. If the FDA disagrees, and requires new PMAs, HDEs, or PMA/HDE supplements for the modifications, we may be required to recall and to stop marketing the modified versions of our Products.

In addition, before our Products can be marketed in the EU, our Products must obtain a CE Certificate from a notified body. New intended uses of CE marked medical devices falling outside the scope of the current CE Certificate require a completely new conformity assessment before the device can be CE marked and marketed in the EU for the new intended use. The process required to gather necessary information and draw up documentation in order to obtain CE Certification of a medical device in the EU can be expensive and lengthy and its outcome can be uncertain. We may make modifications to our Products in the future that we believe do not or will not require notifications to our notified body or new conformity assessments to permit the maintenance of our current CE Certificate. If the competent authorities of the EU member states or our notified body disagree and require the conduct of a new conformity assessment, the modification of the existing CE Certificate or the issuance of a new CE Certificate, we may be required to recall or suspend the marketing of the modified versions of our Products.

In Japan, new medical devices or new therapeutic uses of medical devices falling outside the scope of the existing approval by the MHLW require a new assessment and approval for each such new device or use. Accordingly, we may be required to obtain a new approval from MHLW before we launch a modified version of our Products or the use of our Products for additional indications. Approval time frames from the MHLW vary from simple notifications to review periods of one or more years, depending on the complexity and risk level of the device. In addition, importation into Japan of medical devices is subject to "Quality Management System (QMS) Ordinance," which includes the equivalent of "Good Import" regulations in the U.S. As with any highly regulated market, significant changes in the regulatory environment could adversely affect our ability to commercialize our Products in Japan.

In the U.S. and other jurisdictions, we also are subject to numerous post-marketing regulatory requirements, which include regulations under the QSR related to the manufacturing of our Products, labeling regulations and medical device reporting regulations, which require us to report to the FDA or comparable regulatory authorities in other jurisdictions and our notified body if our Products cause or contributes to a death or serious injury, or malfunction in a way that would likely cause or contribute to a death or serious injury. In addition, these regulatory requirements may in the future change in a way that adversely affects us. If we fail to comply with present or future regulatory requirements that are applicable to us, we may be subject to enforcement action by the FDA or comparable regulatory authorities in other jurisdictions and notified bodies, which may include any of the following sanctions:

• untitled letters, warning letters, fines, injunctions, consent decrees and civil penalties;

• unanticipated expenditures to address or defend such actions;

• patient notification, or orders for repair, replacement or refunds;

• voluntary or mandatory recall, withdrawal or seizure of our current or future devices;

• administrative detention by the FDA or other regulatory authority in another jurisdiction of medical devices believed to be adulterated or misbranded;

• operating restrictions, suspension or shutdown of production;

• refusal or delay of our requests for PMA or analogous approval for new intended uses for or modifications to our Products or for approval of new devices;

• refusal or delay in obtaining CE Certificates for new intended uses for or modifications to our Products;

• suspension, variation or withdrawal of the CE Certificates granted by our notified body in the EU;

• prohibition or restriction of Products being placed on the market;

• operating restrictions;

• suspension or withdrawal of PMA or analogous approvals that have already been granted;

• refusal to grant export approval for our Products or any device candidates; or

• criminal prosecution.

The occurrence of any of these events could have a material adverse effect on our business, prospects, financial condition and results of operations and cause our stock price to decline.

Over time, we expect to make modifications to our Products that are designed to improve efficacy, reduce side effects, enhance the user experience and other purposes. Modifications to our Products may require approvals of new PMAs, HDEs, or PMA/HDE supplement applications, modified or new CE Certificates and analogous regulatory approvals in other jurisdictions or even require us to cease promoting or to recall the modified versions of our Products until such clearances, approvals or modified or new CE Certificates are obtained, and the FDA, comparable regulatory authorities in other jurisdictions or our notified body may not agree with our conclusions regarding whether new approvals are required.

Any modification to a device approved through the PMA or HDE pathway that impacts the safety or effectiveness of the device requires submission to the FDA and FDA approval of a PMA supplement application or even a new PMA or HDE application, as the case may be. The FDA requires a company to make the determination as to whether a new PMA, HDE or PMA/HDE supplement application is to be filed, but the FDA may review the company’s decision. For example, in the past, we have made initial determinations that certain modifications did not require the filing of a new PMA or PMA/HDE supplement application and have notified the FDA of these changes in our PMA Annual Report, but after its review of our PMA Annual Report, the FDA requested that we submit these modifications to the FDA as a PMA supplement application. From time to time, we may make other changes to the devices, software, packaging, manufacturing facilities and manufacturing processes and may submit additional PMA/HDE supplement applications for these changes. FDA may conduct a facility inspection as part of its review and approval process. In addition, it is possible that the FDA will require a human factors (user interface) study. It is also possible that the FDA may require additional clinical data. We can provide no assurance that we will receive FDA approval for these changes on a timely basis, or at all. We also may make additional changes in the future that we may determine do not require the filing of a new PMA, HDE or PMA/HDE supplement application. The FDA may not agree with our decisions regarding whether the filing of new PMAs, HDEs or PMA/HDE supplement applications are required.

In addition, any substantial change introduced to a medical device or to the quality system certified by our notified body requires a new conformity assessment of the device and can lead to changes to the CE Certificates or the preparation of a new CE Certificate of Conformity. Substantial changes may include, among others, the introduction of a new intended use of the device, a change in its design or a change in the company’s suppliers. Responsibility for determination that a modification constitutes a substantial change lies with the manufacturer of the medical device. We must inform the notified body that conducted the conformity assessment of the Products we market or sell in the EU of any planned substantial changes to our quality system or changes to our Products that could, among other things, affect compliance with the MDR or the devices’ intended use. The notified body will then assess the changes and verify whether they affect the Product’s conformity with the Essential Requirements laid down in Annex I to the MDR or the conditions for the use of the device. If the assessment is favorable, the notified body will issue a new CE Certificate or an addendum to the existing CE Certificate attesting compliance with the Essential Requirements laid down in Annex I to the MDR. There is a risk that the competent authorities of the EU member states or our notified body may disagree with our assessment of the changes introduced to our Products. The competent authorities of the EU member states or our notified body also may come to a different conclusion than the FDA on any given product modification.

In addition, "legacy" medical devices that have obtained a CE Certification under the MDD may in principle continue to be marketed under such CE Certificate until the CE Certificate expires but at the latest by December 31, 2027 or 2028, depending on device class, under transitional provisions as amended in February 2023, provided that the

manufacturer complies with the MDR’s additional requirements related to post-marketing surveillance, market surveillance, vigilance, and registration of economic operators and of devices. However, if such medical devices undergo a significant change in their design or intended use, we would need to obtain a new CE Certificate under the MDR for these devices.

If the FDA disagrees with us and requires us to submit a new PMA, HDE, or PMA/HDE supplement application for then-existing modifications and/or the competent authorities of the EU member states or our notified body disagree with our assessment of the change introduced in a product, its design or its intended use, we may be required to cease promoting or to recall the modified product until we obtain approval and/or until a new conformity assessment has been conducted in relation to the product, as applicable. In addition, we could be subject to significant regulatory fines or other penalties. Furthermore, our Products could be subject to recall if the FDA, comparable regulatory authorities in other jurisdictions, or our notified body determine, for any reason, that our Products are not safe or effective or that appropriate regulatory submissions were not made. Any recall or requirement that we seek additional approvals or clearances could result in significant delays, fines, increased costs associated with modification of a product, loss of revenues and potential operating restrictions imposed by the FDA, comparable foreign regulatory authorities in other jurisdictions, or our notified body. Delays in receipt or failure to receive approvals/certification, or the failure to comply with any other existing or future regulatory requirements, could reduce our sales, profitability and future growth prospects.

In addition to FDA requirements, we will spend considerable time and money complying with other federal, state, local and foreign rules, regulations and guidance and, if we are unable to fully comply with such rules, regulations and guidance, we could face substantial penalties.

We are subject to extensive regulation by the U.S. federal government and the states and other countries in which we conduct our business. U.S. federal government healthcare laws apply when we submit a claim on behalf of a U.S. federal healthcare program beneficiary, or when a customer submits a claim for an item or service that is reimbursed under a U.S. federal government-funded healthcare program, such as Medicare or Medicaid. The laws that affect our ability to operate our business in addition to the Federal Food, Drug, and Cosmetic Act and FDA regulations include, but are not limited to, the following:

• the Federal Anti-Kickback Statute, an intent-based federal criminal statute which prohibits knowingly and willfully offering, providing, soliciting or receiving remuneration of any kind to induce or reward, or in return for, referrals or the purchase, lease, order or recommendation or arranging of any items or services reimbursable by a federal healthcare program;

• the Federal Civil False Claims Act, which imposes civil penalties, including through civil whistleblower or " qui tam" actions, for knowingly submitting or causing the submission of false or fraudulent claims of payment to the federal government, knowingly making, using or causing to be made or used a false statement or record material to payment of a false claim or avoiding, decreasing or concealing an obligation to pay money to the federal government;

• the Federal Criminal False Claims Act, which is similar to the Federal Civil False Claims Act and imposes criminal liability on those that make or present a false, fictitious or fraudulent claim to the federal government;

• Medicare laws and regulations that prescribe requirements for coverage and reimbursement, including the conditions of participation for DME suppliers, and laws prohibiting false claims or unduly influencing selection of products for reimbursement under Medicare and Medicaid;

• healthcare fraud statutes that prohibit false statements and improper claims to any third-party payer;

• the Federal Physician Self-Referral Law, commonly known as the Stark law, which, absent an applicable exception, prohibits physicians from referring Medicare and Medicaid patients to an entity for the provision of certain designated health services (“DHS”), including DME, if the physician (or a member of the physician’s immediate family) has an impermissible financial relationship with that entity and prohibits the DHS entity from billing for such improperly referred services;

• the Federal Beneficiary Anti-Inducement Statute, which prohibits the offering of any remuneration to a beneficiary of Medicare or Medicaid that is likely to influence that beneficiary’s choice of provider or supplier. This can include, but is not limited to, inappropriate provision of patient services including financial assistance. Recent government investigations have focused on this particular prohibition. There are established exceptions from liability, but we cannot guarantee that all of our practices will fall squarely within those exceptions;

• similar state anti-kickback, false claims, insurance fraud and self-referral laws, which may not be limited to government-reimbursed items, as well as state laws that require us to maintain permits or licenses to distribute DME;

• federal and state accreditation and licensing requirements applicable to DME providers and equivalent requirements in other jurisdictions;

• the U.S. Foreign Corrupt Practices Act, which can be used to prosecute companies in the U.S. for arrangements with physicians or other parties outside the U.S. if the physician or party is a government official of another country and the arrangement violates the law of that country;

• the Federal Trade Commission Act, the Lanham Act and similar federal and state laws regulating truthfulness in advertising and consumer protection; and

• the Federal Physician Payments Sunshine Act, the French Sunshine Act and similar state and foreign laws, which require periodic reporting of payments and other transfers of value made to U.S. and French-licensed physicians, teaching hospitals, and in the U.S., physician assistants, nurse practitioners, clinical nurse specialists, certified nurse anesthetists, and certified nurse-midwives.

Similar laws exist in the EU, individual EU member states and other countries. These laws are complemented by EU or national professional codes of practices.

HIPAA provides data privacy and security provisions for safeguarding medical information. Additionally, states in the U.S. are enacting local privacy laws (e.g., California). In the EU, the GDPR harmonizes data privacy laws and rules on the processing of personal data, including patient and employee data, across the EU. The GDPR has a number of strict data protection and security requirements for companies processing data of EU residents, including when such data is transferred outside of the EU. Additionally, we need to comply with analogous privacy laws in other jurisdictions in which we operate, such as the Israeli Privacy Protection Law, the Asia Pacific Economic Cooperation Privacy Framework, and Japan’s Act on the Protection of Personal Information.

The laws and codes of practices applicable to us are subject to evolving interpretations. Moreover, certain U.S. federal and state laws regarding healthcare fraud and abuse and certain laws in other jurisdictions regarding interactions with healthcare professionals and patients are broad and we may be required to restrict certain of our practices to be in compliance with these laws. Healthcare fraud and abuse laws also are complex and even minor, inadvertent irregularities, or even the perception of impropriety, can potentially give rise to claims that a statute has been violated.

Any violation of these laws could have a material adverse effect on our business, prospects, financial condition and results of operations and cause our stock price to decline. Similarly, if there is a change in law, regulation or administrative or judicial interpretations, we may have to change our business practices or our existing business practices could be challenged as unlawful, which likewise could have a material adverse effect on our business, prospects, financial condition and results of operations and cause our stock price to decline. Fines and penalties for violations of these laws and regulations could include severe criminal and civil penalties, including, for example, significant monetary damages, exclusion from participation in the federal healthcare programs and permanent disbarment of key employees. Any penalties, damages, fines, curtailment or restructuring of our operations would adversely affect our ability to operate our business, our prospects and our financial results. In addition, any action against us for violation of these laws, even if we successfully defend against it, could cause us to incur significant legal expenses, divert our management’s attention from the operation of our business and damage our reputation.

In addition, although we believe that we have the required licenses, permits and accreditation to dispense our Products in the future, a regulator could find that we need to obtain additional licenses or permits. We also may be subject to mandatory reaccreditation and other requirements in order to maintain our billing privileges. Failure to satisfy those requirements could cause us to lose our privileges to bill governmental and private payers. If we are required to obtain permits or licenses that we do not already possess, we also may become subject to substantial additional regulation or incur significant expense.

To ensure compliance with Medicare, Medicaid and other regulations, federal and state governmental agencies and their agents, including DME MACs, may conduct audits of our operations to support our claims submitted for reimbursement of items furnished to beneficiaries and health care providers. 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 adversely impact our revenue, financial condition and results of operations.

If we, our collaborative partners, our contract manufacturers or our component suppliers fail to comply with the FDA’s QSR or equivalent regulations established in other countries, the manufacturing and distribution of our Products could be interrupted, and our Product sales and results of operations could suffer.

We, our collaborative partners, our contract manufacturers and our component suppliers are required to comply with the FDA’s QSR and the equivalent quality system requirements imposed by the laws and regulations in other jurisdictions, which are a complex regulatory framework that covers the procedures and documentation of the design, testing, production, control, quality assurance, labeling, packaging, sterilization, storage and shipping of our Products. We cannot assure you that our facilities or our contract manufacturers’ or component suppliers’ facilities would pass any future quality system inspection. If our or any of our contract manufacturers’ or component suppliers’ facilities fails a quality system inspection, the manufacturing or distribution of our Products could be interrupted and our operations disrupted. Failure to take adequate and timely corrective action in response to an adverse quality system inspection could force a suspension or shutdown of our packaging and labeling operations or the manufacturing operations of our contract manufacturers, and lead to suspension, variation or withdrawal of our regulatory approvals or a recall of our Products. If any of these events occurs, we may not be able to provide our customers with our Products on a timely basis, our reputation could be harmed and we could lose customers, any or all of which could have a material adverse effect on our business, prospects, financial condition and results of operations and cause our stock price to decline.

Our Products may in the future be subject to recalls that could harm our reputation, business and financial results.

The FDA and similar governmental authorities in other jurisdictions have the authority to require the recall of commercialized products in the event of material deficiencies or defects in design or manufacture. In the case of the FDA, the authority to require a recall must be based on an FDA finding that there is a reasonable probability that the device would cause serious injury or death. In addition, governmental bodies in other jurisdictions have the authority to require the recall of our Products in the event of material deficiencies or defects in design or manufacture. Distributors and manufacturers may, under their own initiative, recall a product if any material deficiency in a device is found. A government-mandated or voluntary recall by us or one of our manufacturers could occur as a result of component failures, manufacturing errors, design or labeling defects or other deficiencies and issues. The FDA requires that certain classifications of recalls be reported to the FDA within ten working days after the recall is initiated. Requirements for the reporting of product recalls to the competent authorities are imposed in other jurisdictions in which our Products are or would be marketed in the future. Companies are required to maintain certain records of recalls, even if they are not reportable to the FDA or to the competent authorities of other countries. In the future, we may initiate voluntary recalls involving our Products that we determine do not require notification of the FDA or to other equivalent non-U.S. authorities. If the FDA or the equivalent non-U.S. authorities disagree with our determinations, they could require us to report those actions as recalls. A future recall announcement could harm our reputation with customers and negatively affect our sales. In addition, the FDA and the equivalent non-U.S. authorities could take enforcement action if we fail to report the recalls when they were conducted. Recalls of our Products would divert managerial and financial resources and could have a material adverse effect on our business, prospects, financial condition and results of operations and cause our stock price to decline.

If our Products cause or contribute to a death or a serious injury, or malfunction in certain ways, we will be subject to medical device reporting regulations, which can result in voluntary corrective actions or agency enforcement actions.

Under the FDA Medical Device Reporting regulations and the equivalent regulations applicable in other jurisdictions in which our Products are or may be marketed in the future, medical device manufacturers are required to report to the FDA and to the equivalent non-U.S. authorities information that a device has or may have caused or contributed to a death or serious injury or has malfunctioned in a way that would likely cause or contribute to death or serious injury if the malfunction of the device or one of our similar devices were to recur. If we fail to report these events to the FDA or to the equivalent authorities in other jurisdictions within the required time frames, or at all, the FDA or the equivalent authorities in other jurisdictions could take enforcement action against us. Any such adverse event involving our Products also could result in future voluntary corrective actions, such as recalls or customer notifications, or agency action, such as inspection or enforcement action. Any corrective action, whether voluntary or involuntary, as well as defending ourselves in a lawsuit, will require the dedication of our time and capital, distract management from operating our business, and may harm our reputation and financial results.

We may be subject to fines, penalties or injunctions if we are determined to be promoting the use of our Products for unapproved or off-label uses.

Medical devices may be marketed only for the indications for which they are approved. Our promotional materials and training materials must comply with FDA regulations and other applicable laws and regulations governing the promotion of our Products in the U.S. and other jurisdictions. Currently, our Products are only approved in certain countries for specific types of cancer, together with specific types of other therapies, such as temozolomide for GBM and PD-1/PD-L1 inhibitors for NSCLC.

If the FDA or the competent authorities in other jurisdictions, including the EU member states, determine that our promotional materials or training constitutes promotion of an unapproved use, they could request that we modify our training or promotional materials or subject us to regulatory or enforcement actions, including the issuance of an untitled or warning letter, an injunction, seizure, civil fines and criminal penalties. It is also possible that authorities in other federal, state or national enforcement in other jurisdictions might take action if they consider our promotional or training materials to constitute promotion of an unapproved use, which could result in significant fines or penalties under other statutory authorities, such as laws prohibiting false claims for reimbursement. In that event, our reputation could be damaged and the commercialization of our Products could be impaired.

We pay taxes, including tariffs, in multiple jurisdictions and adverse determinations by taxing or other governmental authorities or changes in tax laws, rates or our status under which tax jurisdictions apply to us could increase our tax burden or otherwise affect our financial condition or results of operations, as well as subject our shareholders to additional taxes.

The amount of taxes we pay is subject to a variety of tax and customs laws in the various jurisdictions in which we and our subsidiaries are organized and operate. Our domestic and international tax and tariff liabilities are dependent on the location of goods or earnings among these various jurisdictions. Such liabilities could be affected by changes in tax or other laws, treaties, and regulations, as well as the interpretation or enforcement thereof by tax, customs or other governmental entities in any relevant jurisdiction. The amount we pay in tax and tariffs to any particular jurisdiction depends, in part, on the correct interpretation of the relevant laws in such jurisdiction, and we have made a number of determinations as to the effect of such laws in our particular circumstances. In some cases, the determinations we have made as to the effect of the laws in a particular jurisdiction depend on the continuing effectiveness of administrative rulings we have received from the authorities in that jurisdiction, while in other cases, our determinations are based on the reasoned judgment of our advisors. Although we believe that we are in compliance with the administrative rulings we have received, that the assumptions made by our advisors in rendering their advice remain correct, and that as a result we are in compliance with applicable tax and customs laws in the jurisdictions where we and our subsidiaries are organized and operate, an appropriate authority in any such jurisdiction may challenge our interpretation of those laws and assess us or any of our subsidiaries with additional taxes, tariffs, penalties, fees and interest.

Additionally, from time to time, proposals can be made and legislation can be introduced to change the tax and other laws, regulations or interpretations thereof (possibly with retroactive effect) of various jurisdictions or limit treaty benefits that, if enacted, could materially increase our tax and tariff burden, increase our effective tax rate or otherwise have a material adverse impact on our financial condition and results of operations. For example, the Organization for Economic Cooperation and Development (OECD) has secured agreements from many countries to fundamentally rewrite international tax rules and create a minimum global tax, which could impact the amount of tax we will pay in the future. We also cannot predict the effect on our tax and tariff burden, if any, of the imposition of new or increased tariffs by one country and the response of other countries that retaliate in response. It is possible that these changes could adversely affect our business. While we monitor proposals and other developments that would materially impact our tax and tariff burden and effective tax rate and investigate our options accordingly, we could still be subject to increased taxation on a going forward and retroactive basis no matter what action we undertake if certain legislative proposals or regulatory changes are enacted, certain treaties are amended and/or our interpretation of applicable tax or other laws is challenged and determined to be incorrect. Any alternative interpretations of applicable tax and other laws asserted by an authority or changes in tax and customs laws, regulations or accounting principles that limit our ability to take advantage of treaties between jurisdictions, modify or eliminate the deductibility of various currently deductible payments, increase the tax and tariff burden of operating or being resident in a particular country, result in transfer pricing adjustments or otherwise require the payment of additional taxes or levies, may have a material adverse effect on our cash flows, financial condition and results of operations. The termination or revision of any of our rulings or indirect exemptions that we have or may have in the future may have a material adverse effect on our cash flows, financial condition and results of operations.

We are affected by and subject to environmental laws and regulations that could be costly to comply with or that may result in costly liabilities.

We are subject to environmental laws and regulations, including those that impose various environmental controls on the manufacturing, transportation, storage, use and disposal of batteries and chemicals and other materials used in, and hazardous waste produced by, the manufacturing of our Products. We incur and expect to continue to incur costs to comply with these environmental laws and regulations. Additional or modified environmental laws and regulations, including those relating to the manufacture, transportation, storage, use and disposal of materials used to manufacture our Products or restricting disposal or transportation of batteries, may be imposed that may result in higher costs. For example, our products contain per- and polyfluoroalkyl substances (PFAS), and we may be subject to reporting laws or regulations for products containing these substances, such as the Federal Toxic Substances Control Act (TCSA) of 1976 in the U.S.,and/or similar laws at the State level.

In addition, we cannot predict the effect that additional or modified environmental laws and regulations may have on us, our third-party suppliers of equipment, batteries and our Products or our customers. For example, we and our suppliers rely on the exemption in European Directive 2011/65/EU relating to the restriction of the use of certain hazardous substances in electrical and electronic equipment, set out in Annex IV, relating to lead content in our arrays. To the extent this exemption is revoked or amended, it may have a material impact on our business and results of operations.

Safety issues concerning lithium-ion batteries could have a material adverse impact on our business.

Our Products use lithium-ion batteries. On rare occasions, lithium-ion cells can rapidly release the energy they contain by venting smoke, heat, and flames in a manner that can ignite nearby materials as well as other lithium-ion cells. A failure in the lithium-ion battery contained in a Product could occur, which could result in accidents, casualty or damages, and subject us to lawsuits, product recalls, or redesign efforts. In addition, we store a significant number of lithium-ion cells at our facilities. Any failure of battery cells or a safety issue or fire related to the cells could disrupt our operations. Such damage or injury could lead to adverse publicity and potentially a safety recall. The transportation of lithium and lithium-ion batteries is regulated worldwide.

Laws regulating the transportation of batteries have been and may be enacted which could impose additional costs that could harm our ability to be profitable. If additional restrictions are put in place that limit our ability to ship our Products by air freight or on water borne cargo, such restrictions could have an adverse effect on our supply chain, our inventory management procedures and processes and our ability to fill prescriptions and service patients in a timely manner, which could have a material adverse effect on our business, prospects, financial condition and results of operations. In addition, compliance with future worldwide or International Air Transport Association approval process and regulations could require significant time and resources from our technical staff and, if redesign were necessary, could delay the introduction of new Products.

Risks relating to intellectual property

If we fail to maintain, develop, protect, defend or enforce our intellectual property rights, including to our proprietary technology, trade secrets or know how, competitors may be able to develop competing therapies.

Our success depends, in part, on our ability to obtain and maintain protection for our Products and technologies under the patent laws or other intellectual property laws of the U.S. and other countries. The standards that the U.S. Patent and Trademark Office ("USPTO") and its counterparts in other jurisdictions use to grant patents are not always applied predictably or uniformly and can change. Consequently, we cannot be certain as to whether pending patent applications will result in issued patents, and we cannot be certain as to the type and extent of patent claims that may be issued to us in the future. Any issued patents may not contain claims that will permit us to stop competitors from using similar technology.

Our current intellectual property portfolio consists of hundreds of issued patents in multiple jurisdictions covering various aspects of our devices and related technology. The legal scope of our patents vary, with some having broad coverage and others having narrow coverage, for example being limited to certain intensities and frequencies. Our patent position is generally uncertain and involves complex legal and factual questions.

In the U.S., our patents have expected expiration dates between 2025 and 2041. Starting in 2021, several patents covering technology included in our Products have expired in the U.S. and elsewhere. Patent expiration could adversely affect our ability to protect our Products and future product development and our competitors may develop and market competing products. We have also filed additional patent applications in several countries that

may never be issued. Consequently, our operating results and financial position could be materially adversely affected. In addition, due to the extensive time needed to develop, test and obtain regulatory approval for our treatment therapies, any patents that protect our Product candidates may expire early during commercialization. This may reduce or eliminate any market advantages that such patents may give us and harm our financial position. If we fail to develop and successfully launch new Products prior to the expiration of patents for our existing Products, our sales and achieving patient acceptance with respect to those Products could decline significantly. We may not be able to develop and successfully launch more advanced replacement Products before these and other patents expire.

We have limited intellectual property rights outside of our key markets. In some countries outside the U.S., we do not have any intellectual property rights, and our intellectual property rights in other countries outside the U.S. have a different scope and strength compared to our intellectual property rights in the U.S. Consequently, we may not be able to prevent third parties from practicing our inventions in all countries outside the U.S. Competitors may use our technologies in jurisdictions where we have not obtained patent protection to develop their own products and further, may export otherwise infringing products to territories where we have patent protection, but where enforcement rights are not as strong as those in the U.S. These products may compete with our devices, and our patents or other intellectual property rights may not be effective or adequate to prevent such competition.

For a variety of reasons, we may decide not to file for patent protection for certain of our intellectual property. Our patent rights underlying TTFields and our Products may not be adequate, and our competitors or customers may design around our proprietary technologies or independently develop similar or alternative technologies or products that are equal or superior to ours without infringing on any of our patent rights. In addition, the patents licensed or issued to us may not provide a competitive advantage, and may be insufficient to prevent others from commercializing products similar or identical to ours. The occurrence of any of these events could have a material adverse effect on our business, prospects, financial condition and results of operations and cause our stock price to decline.

Our existing and future patent portfolio also is vulnerable to legal challenges worldwide. The standards that courts use to interpret patents are not always applied predictably or uniformly and can change from country to country, particularly as new technologies develop. As a result of the uncertainties of patent law in general, we cannot predict how much protection, if any, will be given to our patents when we attempt to enforce them and they are challenged in court. Any attempt to enforce our intellectual property rights may also be time-consuming and costly, may divert the attention of management from our business, may ultimately be unsuccessful or may result in a remedy that is not commercially valuable. Such attempts often provoke third parties to assert claims against us or result in our intellectual property being narrowed in scope or declared to be invalid or unenforceable.

In addition, we rely on certain proprietary trade secrets, know-how and other confidential information. We have taken measures to protect our unpatented trade secrets, know-how and other confidential information, including the use of confidentiality and assignment of inventions agreements with our employees, consultants and certain contractors. It is possible, however, that these persons may breach or challenge the agreements, that our trade secrets may otherwise be misappropriated or that competitors may independently develop or otherwise discover our trade secrets. There is therefore no guarantee that we will be able to obtain, maintain and enforce the intellectual property rights that may be necessary to protect and grow our business and to provide us with a meaningful competitive advantage, and our failure to do so could have a material adverse effect on our business, prospects, financial condition and results of operations and cause our stock price to decline.

The oncology and medical device industries are characterized by patent and other intellectual property litigation and disputes, and any litigation, dispute or claim against us may cause us to incur substantial costs, could place a significant strain on our financial resources, divert the attention of management from our business, harm our reputation and require us to remove certain devices from the market.

Whether a product infringes a patent or violates other intellectual property rights involves complex legal and factual issues, the determination of which is often uncertain. Any intellectual property dispute, even a meritless or unsuccessful one, would be time consuming and expensive to defend and could result in the diversion of our management’s attention from our business and result in adverse publicity, the disruption of research and development and marketing efforts, injury to our reputation and loss of revenues. Any of these events could negatively affect our business, prospects, financial condition and results of operations.

Third parties may assert that TTFields, our Products, the methods employed in the use of our Products or other activities infringe on their patents. Such claims may be made by competitors seeking to obtain a competitive advantage or by other parties, many of whom have significantly larger intellectual property portfolios than we have.

Additionally, in recent years, individuals and groups have begun purchasing intellectual property assets for the purpose of making claims of infringement and attempting to extract settlements from companies like ours. With respect to our current Products, the risk of infringement claims is exacerbated by the fact that there are numerous issued and pending patents relating to the treatment of cancer. Because patent applications can take many years to issue, and in many cases remain unpublished for many months after filing, there may be applications now pending of which we are unaware that may later result in issued patents that our Products may infringe.

There could also be existing patents that one or more components of our Products or other device candidates may inadvertently infringe. As the number of competitors in the market or other device candidates grows, the possibility of inadvertent patent infringement by us or a patent infringement claim against us increases. To the extent we gain greater market visibility, our risk of being subject to such claims is also likely to increase. If a third party’s patent was upheld as valid and enforceable and we were found to be infringing, we could be prevented from making, using, selling, offering to sell or importing our Products or other device candidates, unless we were able to obtain a license under that patent or to redesign our systems to avoid infringement. A license may not be available at all or on terms acceptable to us, and we may not be able to redesign our Products to avoid any infringement. Modification of our Products or development of device candidates to avoid infringement could require us to conduct additional clinical studies and to revise our filings with the FDA and other regulatory bodies, which would be time-consuming and expensive. If we are not successful in obtaining a license or redesigning our devices, we may be unable to make, use, sell, offer to sell or import our devices and our business could suffer. We may also be required to pay substantial damages and undertake remedial activities, which could cause our business to suffer.

We may also be subject to claims alleging that we infringe or violate other intellectual property rights, such as copyrights or trademarks, may have to defend against allegations that we misappropriated trade secrets, and may face claims based on competing claims of ownership of our intellectual property. The confidentiality and assignment of inventions agreements that our employees, consultants and other third parties sign may not in all cases be enforceable or sufficient to protect our intellectual property rights. In addition, we may face claims from third parties based on competing claims to ownership of our intellectual property.

We also employ individuals who were previously employed at other medical device companies, and as such we may be subject to claims that such employees have inadvertently or otherwise used or disclosed the alleged trade secrets or other proprietary information of their former employers. Any such litigation, dispute or claim could be costly to defend and could subject us to substantial damages, injunctions or other remedies, which could have a material adverse effect on our business, prospects, financial condition and results of operations and cause our stock price to decline.

Changes in U.S. patent law could diminish the value of patents in general, thereby impairing our ability to protect our devices.

As is the case with other medical device companies, our success is heavily dependent on our intellectual property rights, and particularly on our patent rights. Obtaining and enforcing patents in the medical device industry involves both technological and legal complexity, and is therefore costly, time consuming and inherently uncertain. In addition, the U.S. has recently enacted and is currently implementing wide-ranging patent reform legislation. Certain U.S. Supreme Court rulings have narrowed the scope of patent protection available in certain circumstances and weakened the rights of patent owners in certain situations. In addition to increasing uncertainty with regard to our ability to obtain patents in the future, this combination of events has created uncertainty with respect to the value of patents once obtained. Depending on decisions by the U.S. Congress, the federal courts and the USPTO, the laws and regulations governing patents could change in unpredictable ways that could further negatively impact the value of our patents, narrow the scope of available patent protection or weaken the rights of patent owners.

Risks relating to our ordinary shares and capital structure

The market price for our ordinary shares may be volatile, which could result in substantial losses.

The market price for our ordinary shares may be volatile and subject to wide fluctuations in response to factors such as publication of clinical studies relating to our Products, our system candidates or a competitor’s product, actual or anticipated fluctuations in our quarterly results of operations, changes in financial estimates by securities research analysts, negative publicity, studies or reports, changes in the economic performance or market valuations of other companies that operate in our industry, changes in the availability of third-party reimbursement in the U.S. or other countries, changes in governmental regulations or in the status of our regulatory approvals or applications, announcements by us or our competitors of material acquisitions, strategic partnerships, joint ventures or capital

commitments, intellectual property litigation, release of transfer restrictions on our outstanding ordinary shares, and economic or political conditions in the U.S. or elsewhere.

Our ordinary shares are issued under the laws of Jersey, which may not provide the level of legal certainty and transparency afforded by incorporation in a U.S. state.

We are incorporated under the laws of the Bailiwick of Jersey, Channel Islands. Jersey legislation regarding companies is largely based on English corporate law principles. However, there can be no assurance that Jersey law will not change in the future or that it will serve to protect investors in a similar fashion afforded under corporate law principles in the U.S., which could adversely affect the rights of investors.

U.S. shareholders may not be able to enforce civil liabilities against us.

We are a Jersey entity with most of our assets located outside of the U.S. Although we have appointed an agent for service of process in the U.S. for purposes of U.S. federal securities laws, a number of our directors and executive officers and a number of directors of each of our subsidiaries are not residents of the U.S., and all or a substantial portion of the assets of such persons are located outside the U.S. As a result, it may not be possible for investors to effect service of process within the U.S. upon such persons or to enforce against them judgments obtained in U.S. courts predicated upon the civil liability provisions of the federal securities laws of the U.S.

We have been advised by our Jersey lawyers that the courts of Jersey would recognize any final and conclusive judgment under which a sum of money is payable (not being a sum payable in respect of taxes or other charges of a like nature or in respect of a fine or other penalty) obtained against us in the courts of any other territory in respect of certain enforceable obligations in accordance with the principles of private international law as applied by Jersey law (which are broadly similar to the principles accepted under English common law) and such judgment would be sufficient to form the basis of proceedings in the Jersey courts for a claim for liquidated damages in the amount of such judgment. In such proceedings, the Jersey courts would not re-hear the case on its merits save in accordance with such principles of private international law. Obligations may not necessarily be enforceable in Jersey in all circumstances or in accordance with their terms; and in particular, but without limitation: (i) any agreement purporting to provide for a payment to be made in the event of a breach of such agreement would not be enforceable to the extent that the Jersey courts were to construe such payment to be a penalty that was excessive, in that it unreasonably exceeds the maximum damages that an obligee could have suffered as a result of the breach of an obligation; (ii) the Jersey courts may refuse to give effect to any provision in an agreement that would involve the enforcement of any revenue or penal laws in other jurisdictions; and (iii) the Jersey courts may refuse to allow unjust enrichment or to give effect to any provisions of an agreement (including provisions relating to contractual interest on a judgment debt) that it considers usurious.

We have borrowed a significant amount of debt and have the ability to borrow additional debt in the future, which could adversely affect our financial condition and results of operations and our ability to react and make changes to our business.

We are party to a five-year senior secured credit facility (the "Facility") among Novocure Luxembourg S.a.r.l., our wholly-owned subsidiary, and BPCR Limited Partnership and BioPharma Credit Investments V (Master) LP (collectively, the "Lenders"), BioPharma Credit PLC, as collateral agent for the Lenders, and other of our subsidiaries that are guarantors to such agreement. As of December 31, 2025, we have borrowed $200.0 million under the Facility. The maximum amount we could have borrowed under the Facility was $400.0 million; however, we did not exercise our option to draw down additional amounts under the Facility in 2025. Therefore we are not eligible to draw down any further amounts.

The Facility contains usual and customary restrictive covenants relating to the operation of our business, including restrictions on our ability:

• to incur or guarantee additional indebtedness;

• to incur or permit to exist certain liens;

• to enter into certain sale and lease-back transactions;

• to make certain investments, loans and advances;

• to effect certain mergers, consolidations, asset sales and acquisitions;

• to pay dividends on, or redeem or repurchase, capital stock, enter into transactions with affiliates or materially change our business; and

• to repay or modify certain other agreements with respect to other material indebtedness or modify our organizational documents.

Our ability to service the Facility indebtedness and incur and service indebtedness in the future could be impacted by interest and currency rate fluctuations.

Our existing indebtedness and any additional indebtedness we may incur otherwise could require us to divert funds identified for other purposes for debt service and impair our liquidity position.

The fact that a substantial portion of our cash flow from operations could be needed to make payments on our indebtedness could have important consequences, including the following:

• increasing our vulnerability to general adverse economic and industry conditions or increased interests rates;

• limiting the availability of our cash flow for other purposes and our flexibility in planning for or reacting to changes in our business and the markets in which we operate, which would place us at a competitive disadvantage compared to our competitors that may have less exposure to debt;

• limiting our ability to borrow additional funds for working capital, capital expenditures and other investments; and

• failing to comply with the covenants in our debt agreements could result in all of our indebtedness becoming immediately due and payable.

Our ability to obtain necessary funds through borrowing, as well as our ability to service our indebtedness, will depend on our ability to generate cash flow from operations. Our ability to generate cash is subject to general economic, financial, competitive, legislative, regulatory and other factors that are beyond our control. If our business does not generate sufficient cash flow from operations or if future borrowings are not available to us under our outstanding borrowings or otherwise in amounts sufficient to enable us to fund our liquidity needs, our financial condition and results of operations may be adversely affected. Our inability to make scheduled payments on our debt obligations in the future would require us to refinance all or a portion of our indebtedness on or before maturity, sell assets or seek additional equity investment. We may not be able to take any of such actions on a timely basis, on terms satisfactory to us or at all.

ITEM 7. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

Management’s Discussion and Analysis of Financial Condition and Results of Operations ("MD&A") is intended to provide information to assist you in better understanding and evaluating our financial condition and results of operations. We encourage you to read this MD&A in conjunction with our consolidated financial statements and the notes thereto included in Part II, Item 8 of this Annual Report on Form 10-K. This discussion contains forward-looking statements that involve risks and uncertainties. Please refer to the information under the heading "Cautionary Note Regarding Forward-Looking Statements" elsewhere in this report. References to the words "we," "our," "us," and the "Company" in this report refer to NovoCure Limited, including its consolidated subsidiaries .

Commentary on Results of Operations

Net revenues

Our revenues are primarily derived from patients using our Products in our active markets. We charge for treatment with our Products on a monthly basis. Our potential net revenues per patient are determined by our ability to secure payment, the monthly fee we collect and the number of months that the patient remains on therapy.

We also receive revenues pursuant to the Zai Agreement. For additional information regarding the Zai Agreement, see Note 12 to the Consolidated Financial Statements.

Cost of revenues

We contract with third parties to manufacture our Products. Our cost of revenues is primarily comprised of the following:

• disposable arrays;

• depreciation expense for the field equipment, including the electric field generator used by patients; and

• personnel and overhead costs such as facilities, freight and depreciation of property, plant and equipment associated with managing our inventory, warehousing and order fulfillment functions.

Operating expenses

Our operating expenses consist of research, development and clinical studies, sales and marketing and general and administrative expenses. Personnel costs are a significant component for each category of operating expenses and consist of wages, benefits and bonuses. Personnel costs also include share-based compensation.

Research, development and clinical studies

Our research, development and clinical studies activity is focused on advancing TTFields therapy through clinical studies across multiple solid tumor types and improving the efficacy and usability of our devices. Research, development and clinical studies costs, including direct and allocated expenses, are expensed as incurred and consist primarily of the following:

• personnel costs for those employees involved in our preclinical and basic research, clinical development programs, clinical affairs, product development and regulatory activities;

• costs to conduct research, product development and clinical study activity through agreements with contract research organizations and other third parties;

• manufacturing expenses associated with our Products, including durable components and disposable arrays, utilized in clinical studies and other research;

• costs associated with publications, presentations and investigator-sponsored trials;

• professional fees related to regulatory approvals and conformity assessment procedures; and

• facilities, depreciation and other allocated expenses, which include direct and allocated expenses for rent and maintenance of facilities, depreciation of leasehold improvements and equipment and laboratory and other supplies.

The following table summarizes our research, development and clinical study expenses by program for the years ended December 31, 2025, 2024 and 2023:

We are committed to investing strategically to maximize the growth potential of the TTFields therapy platform. As such, we are prioritizing clinical programs which have the greatest value potential in solid tumors where TTFields therapy has established efficacy and an unmet clinical need for biophysical treatment exists, including glioblastoma, pancreatic cancer and non-small cell lung cancer.

Sales and marketing

Sales and marketing expenses consist primarily of personnel costs, travel, marketing and promotional activities, medical education, market access, commercial shipping and facilities costs. Over the next few years, we expect to continue to make significant expenditures associated with selling and marketing our Products, primarily in connection with continued commercialization in North America, the EU and Japan for the treatment of our approved indications. We will continue to prioritize launch readiness, including field-based commercial and field-based medical team hiring, for the anticipated approval of TTFields therapy for the treatment of pancreatic cancer outside the United States and for future new indications around the world.

General and administrative

General and administrative expenses consist primarily of personnel, professional fees and facilities costs. General and administrative personnel costs include our executive, finance, human resources, information technology and legal functions. These costs also include our contributions to support industry and patient groups. Our professional fees consist primarily of accounting, information technology, legal and other consulting costs. We believe we have largely built out the structure to support a global multi-indication oncology company and will look to moderate general and administrative expense growth to achieve profitability.

In addition, we incur significant legal and accounting costs related to compliance with SEC rules and regulations, including the costs of achieving and maintaining compliance with Section 404 of the Sarbanes-Oxley Act of 2002 and compliance with rules of the NASDAQ Stock Market, as well as insurance, investor relations and other costs associated with being a public company.

Financial expenses, net

Financial expenses, net, primarily consists of bank fees, credit facility interest expense and related debt issuance costs, interest income from cash balances and short-term investments and gains (losses) from foreign currency transactions. Our reporting currency is the U.S. dollar. We have historically held substantially all of our cash balances in U.S. dollar denominated accounts to minimize the risk of translational currency exposure.

Critical accounting policies and estimates

In accordance with U.S. GAAP, in preparing our financial statements we must make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities as of the date of the financial statements and the reported amounts of net revenues and expenses during the reporting period. We develop and periodically change these estimates and assumptions based on historical experience and on various other factors that we believe are reasonable under the circumstances. Actual results may differ from these estimates.

The critical accounting policies requiring estimates, assumptions and judgments that we believe have the most significant impact on our consolidated financial statements are described below.

Revenue recognition

The amount of revenue recognized reflects the consideration to which we expect to be entitled to receive in exchange for our Products. For additional information, see Note 2(m) to the Consolidated Financial Statements.

We also receive revenues pursuant to the Zai Agreement. For additional information regarding the Zai Agreement, see Note 12 to the Consolidated Financial Statements.

Share-based compensation

Under the FASB's ASC 718, Compensation-Stock Compensation, we measure and recognize compensation expense for share options granted to our employees and directors and for our ESPP based on the fair value of the awards on the date of grant. The fair value of share options is estimated at the date of grant using the Black-Scholes option pricing model and for market condition awards we also use the Monte-Carlo simulation model. Both models requires management to apply judgment and make estimates, which include models of volatility, term, dividends and interest rates. The computation of expected volatility is based on the historical volatility of our shares. The expected term of options granted is calculated using our historical and future exercise behavior. Historically, we have not paid dividends and have no foreseeable plans to pay dividends. Therefore, we use an expected dividend yield of zero in the option pricing model. The risk-free interest rate is based on the yield of U.S. treasury bonds with equivalent terms.

For information about our ESPP, see Note 15 to the Consolidated Financial Statements.

We recognize share-based compensation costs only for those shares expected to vest over the requisite vesting period of the award, which is generally the option vesting term of four years, using the accelerated method.

We recognize compensation costs for the value of performance stock units ("PSU") over the performance period when the vesting conditions become probable in accordance with ASC 718.

The table below summarizes the assumptions that were used to estimate the fair value of the options granted to employees during the periods presented:

Year ended December 31,

Expected term (years)

Expected volatility

Risk-free interest rate

Dividend yield

If any of the assumptions used in the Black-Scholes option pricing model change significantly, share-based compensation for future awards may differ materially from the awards granted previously.

So long as our ordinary shares are publicly traded in a liquid market, we will rely on the daily trading price of our ordinary shares when we estimate the fair value of options granted.

We incurred share-based compensation expense of $104.8 million, $160.0 million and $115.6 million during the years ended December 31, 2025, 2024 and 2023, respectively. As of December 31, 2025, we have unrecognized compensation expense of $73.8 million, which is expected to be recognized over a weighted average period of approximately 1.45 years years. We expect to continue to grant equity awards in the future, and to the extent that we do, our recognized share-based compensation expense will fluctuate as a significant portion of our awards are tied to our performance. For additional information, see Note 15 to the Consolidated Financial Statements.

Long-lived assets

Field equipment is stated at cost, net of accumulated depreciation. Depreciation is calculated using the straight-line method over the estimated useful life of the relevant asset. We make estimates of the useful life of our field equipment, based on similar assets purchased in the past and our historical experience with such similar assets, in order to determine the depreciation expense to be recorded for each reporting period.

Our field equipment consists of equipment being utilized under rental agreements accounted for on a monthly basis as an operating lease, as well as service pool equipment. Service pool equipment is equipment owned and maintained by us that is swapped for equipment that needs repair or maintenance by us while being used by a patient. We record a provision for any excess, lost or damaged equipment when warranted based on an assessment of the equipment.

We assess impairment whenever events or changes in circumstances indicate that the carrying amount of the asset is impaired or the estimated useful life is no longer appropriate. Circumstances such as changes in technology or in the way an asset is being used may trigger an impairment review. For additional information, see Notes 2(i) and 2(j) to the Consolidated Financial Statements.

Inventories

Inventories are stated at the lower of cost or net realizable value. We regularly evaluate the ability to realize the value of inventory. If the inventories are deemed damaged, if actual demand for our devices declines, or if market conditions are less favorable than those projected, inventory write-offs may be required. For additional information, see Note 2(h) to the Consolidated Financial Statements.

Income taxes

As part of the process of preparing our consolidated financial statements, we are required to calculate our income taxes based on taxable income by jurisdiction. We make certain estimates and judgments in determining our income taxes, including assessment of our uncertain tax positions, for financial statement purposes. Significant changes to these estimates may result in an increase or decrease to our tax provision in the subsequent period when such a change in estimate occurs.

Uncertain tax positions are based on estimates and assumptions that have been deemed reasonable by management. Our estimates of unrecognized tax benefits and potential tax benefits may not be representative of actual outcomes.

For additional information, see Note 14 to the Consolidated Financial Statements.

Key performance indicators

We believe certain commercial operating statistics are useful to investors in evaluating our commercial business as they help investors evaluate and compare the adoption of our Products from period to period. The number of active patients on therapy is our principal revenue driver. An "active patient" is a patient who is receiving treatment under a commercial prescription order as of the measurement date, including patients who may be on a temporary break from treatment and who plan to resume treatment in less than 60 days. Prescriptions are a leading indicator of demand. A "prescription received" is a commercial order for Optune Gio or Optune Lua that is received from a physician certified to treat patients with our Products for a patient not previously on Optune Gio or Optune Lua. Orders to renew or extend treatment are not included in this total. The following tables include certain commercial operating statistics for and as of the end of the periods presented.

Net revenues

Net revenues. Net revenues increased by $50.1 million, or 8%, to $655.4 million for the year ended December 31, 2025 from $605.2 million for the year ended December 31, 2024. The growth in net revenues primarily resulted from a $20.5 million increase from continued growth in France, a $14.1 million increase in Germany from active patient growth and reimbursement improvements, and a $21.7 million increase from the remaining international markets driven by active patient growth and reimbursement improvements in certain markets. The overall increase for the full year includes $10.9 million of exchange rate benefits. This increase was partially offset by $6.2 million less revenue in the United States related to a reduction in one-time benefits of prior period claims. Recognized revenue from Optune Lua in the year was $10.4 million, including $5.8 million from NSCLC, and $4.6 million from MPM.

Cost of revenues

Cost of revenues. Our cost of revenues were $166.9 million for the year ended December 31, 2025, an increase of $29.7 million, or 22%, from $137.2 million for the year ended December 31, 2024, primarily due to 9% growth in Optune Gio active patients, $3.4 million higher array costs driven by the new array roll-out, $3.6 million attributed to the NSCLC launch, $5.2 million in higher tariffs, and $3.1 million more in sales to Zai. In addition, the Company recognized a $3.2 million expense in 2025 related to an inventory obsolescence provision for Optune Lua arrays.

Excluding sales to Zai, cost of revenues per active patient per month were $2,950 for the year ended December 31, 2025 compared to $2,683 for the year ended December 31, 2024. Cost of revenues per active patient is calculated by dividing the cost of revenues for the year less product sales to Zai for the year by the average of the active patients at the end of the each quarter in the current year and the end of the year active patients from the prior year. This annual figure is then divided by twelve to estimate the monthly cost of revenues per active patient. Sales to Zai are deducted because they are made at burdened cost and in anticipation of future royalties from Zai, and Zai patient counts are not included in our active patient population. Product's cost sold to Zai totaled $12.8 million for the year ended December 31, 2025 compared to $9.7 million for the year ended December 31, 2024.

Gross margin was 75% for the year ended December 31, 2025 and 77% for the year ended December 31, 2024. The decrease in gross margin is due to the decrease of prior period claims in the U.S. and the aforementioned higher cost of revenues, mostly related to tariffs and a higher cost per array. We expect that our gross margins will continue to be impacted by our launch of Optune Pax while we seek broad reimbursement, offset by expected decreases in array costs as we attempt to optimize our supply chain. In addition, changes in the tariff environment could impact our future gross margins. Our current analysis of the global tariff environment leads us to believe there should not be a material impact to margins in the short-term and we are actively working to mitigate any potential impacts in the medium to long-term. The tariff environment is changing rapidly, and we cannot be assured that we will not ultimately be negatively impacted by these changes. We continue to focus on opportunities to increase efficiencies and scale within our supply chain. This focus includes evaluating new materials, manufacturers, structures and processes that could lead to lower costs.

Total operating expenses

Research, development and clinical studies expenses. Research, development and clinical studies expenses increased by $14.9 million, or 7%, to $224.5 million for the year ended December 31, 2025 from $209.6 million for the year ended December 31, 2024. The change was primarily due to a $7.1 million increase in product development costs, an $11.5 million increase in other research and development costs mainly from a $3.7 million

increase in regulatory expenses and a $3.1 million increase in quality and safety expenses, and $2.6 million in direct clinical trial expenses related to the ramp up of the LUNAR-2 and KEYNOTE D58 trials, partially offset by $7.2 million lower share-based compensation.

Total research and development expenses can fluctuate period-to-period dependent upon the amount of clinical research organization services delivered, clinical materials procured and the number of trials actively underway within a given period.

Sales and marketing expenses. Sales and marketing expenses increased by $1.0 million, or 0.4%, to $240.1 million for the year ended December 31, 2025 from $239.1 million for the year ended December 31, 2024. The change was primarily due to an increase of $8.1 million in costs related to a sales force expansion, a $4.0 million increase in marketing expenses related to the NSCLC launch and new indication preparations, a $2.8 million increase in market access costs related to securing reimbursements in new indications and new geographies, and a $2.1 million increase in other expenses, partially offset by a $16.0 million reduction in share-based compensation.

General and administrative expenses. General and administrative expenses decreased by $12.2 million, or 6%, to $177.7 million for the year ended December 31, 2025 from $189.8 million for the year ended December 31, 2024. The decrease primarily results from a $28.8 million decrease in share-based compensation, which was the result of non-recurring shared-based compensation mostly related to the indication approval for NSCLC in 2024, partially offset by $12.8 million higher personnel and professional service expenses to support the greater company build-out to support new indications, particularly in enterprise technology as we invest in our digital infrastructure to enable scale, a $1.6 million one-time expense of obsolete technology assets, and a $2.2 million one-time expense to retire a production line related to supply chain optimization efforts.

Financial income, net, decreased by $21.8 million, or 55%, to $17.5 million income for the year ended December 31, 2025 from $39.3 million income for the year ended December 31, 2024. The decrease was primarily driven by a decrease in interest income of $11.3 million primarily driven by lower U.S. interest rates and a reduction in our short term investments due to repayment of the convertible note, an increase of $5.7 million in interest expenses from our senior secured term loan credit facility, and an increase of $3.6 million in foreign exchange expenses, offset by a gain from the purchase of convertible notes of $1.1 million.

Income tax

Income taxes. Income tax expenses decreased by $37.5 million, or 100%, resulting in a tax benefit of $0.0 million for the year ended December 31, 2025 compared to a tax expense of $37.5 million for the year ended December 31, 2024. The decrease primarily reflects a one-time $14.2 million reduction from a prior year return to provision related to a filing position for the tax treatment of share-based compensation, an $11.1 million increase in current year tax benefits from share-based compensation, a primarily one-time $8.9 million reduction due to favorable U.S. tax law changes, and a $4.3 million reduction due to intercompany interest income in Switzerland and Luxembourg.

Non-GAAP financial measures

We also measure our performance based upon a non-U.S. GAAP measurement of earnings before interest, taxes, depreciation, amortization and shared-based compensation ("Adjusted EBITDA"). We believe Adjusted EBITDA is useful to investors in evaluating our operating performance because it helps investors evaluate and compare the results of our operations from period to period by removing the impact of earnings attributable to our capital structure, tax rate and material non-cash items, specifically share-based compensation.

We calculate Adjusted EBITDA as operating income before financial expenses and income taxes, net of depreciation, amortization and share-based compensation. The following table reconciles net loss (which is the

most directly comparable U.S. GAAP operating performance measure) to Adjusted EBITDA.

Year ended December 31,

Net income (loss)

Add: Income tax

Add: Financial expenses (income), net

Adjusted EBITDA

Adjusted EBITDA decreased by $35.1 million to $(34.3) million for the year ended December 31, 2025 from $0.8 million for the year ended December 31, 2024. The change in Adjusted EBITDA was primarily due to revenue growth from Optune Gio being offset by increasing costs for new indications. Revenue increases drove a $20.4 million increase in gross profit. The gross profit increase was offset by increased operating expenses, primarily due to our launch in NSCLC and prelaunch activities for potential new indications. We intend to take actions that prioritize growth and maintain financial health as we position our company for future profitability.

Liquidity and capital resources

We have incurred significant losses and cumulative negative cash flows from operations with only limited and intermittent operating profits since our founding in 2000. As of December 31, 2025, we had an accumulated deficit of $1,290.4 million. To date, we primarily have financed our operations through the issuance and sale of equity and the proceeds from long-term loans.

At December 31, 2025, we had $93.5 million in cash and cash equivalents and $354.1 million in short-term investments. At December 31, 2025, our cash, cash equivalents and short-term investments totaled $447.7 million, a decrease of $512.2 million compared to $959.9 million at December 31, 2024. The decrease was primarily due to net cash used in financing activities, primarily attributable to the repayment of the convertible note at maturity of $560.9 million offset by proceeds of $100 million from the Tranche B Loan of the senior secured term loan credit facility.

We believe our cash, cash equivalents and short-term investments as of December 31, 2025 are sufficient for our operations for at least the next 12 months based on our existing business plan and our ability to control the timing of significant expense commitments. We expect that our research, development and clinical expenses, sales and marketing expenses and general and administrative expenses will continue to increase over the next several years and may outpace our gross profit. As a result, we may need to raise additional capital to fund our operations.

The following summary of our cash flows for the periods indicated has been derived from our consolidated financial statements, which are included elsewhere in this Annual Report:

Operating activities

Net cash used in operating activities primarily represents our net loss for the periods presented. Adjustments to net loss for non-cash items include share-based compensation, depreciation, amortization and asset write-downs. Operating cash flows are also impacted by changes in operating assets and liabilities, principally trade payables, deferred revenues, other payables, prepaid expenses, inventory and trade receivables.

Net cash used in operating activities was $49.0 million for the year ended December 31, 2025 compared to $26.4 million used in operating activities for the year ended December 31, 2024 an increase of net cash used in operating

activities by $22.1 million. The increase in net cash used in operating activities was driven by a decrease of net loss of $32.4 million, offset by a decrease in cash to non-cash items of $38.6 million which is primarily driven by a decrease in shared-based compensation of $55.2 million, an increase in accrued interest of $ 5.6 million, an increase of $3.7 million in asset write-downs and impairment of field equipment and an increase of $3.4 million in depreciation and amortization. In addition, the increase in net cash used in operating activities is driven by an increase in working capital of $21.0 million, which was primarily driven by an increase in accounts receivable of $12.6 million and an increase of $8.2 million in inventories.

Upcoming use of cash in operations will include payments in the normal course of business of $49.1 million in purchase obligations with certain of our suppliers, primarily for the purchase of Product components along with other commitments to purchase goods or services. These amounts include approximately $41.9 million of commitments with four major suppliers. We make such commitments through a combination of purchase orders, supplier contracts, and open orders based on projected demand information. We also have employment agreements with certain employees that require the funding of a specific level of payments if certain events, such as a change in control or termination without cause, occur. In the course of normal business operations, we also have agreements with contract service providers to assist in the performance of our research and development (including clinical studies) and manufacturing activities. We could also enter into additional collaborative research, contract research, manufacturing and supplier agreements in the future, which may require up-front payments and even long-term commitments of cash.

Investing activities

Our investing activities primarily consist of investments in and redemptions of short-term investments, as well as capital expenditures to purchase property and equipment and field equipment.

Net cash provided by investing activities was $437.3 million for the year ended December 31, 2025 compared to net cash used in investing activities of $140.2 million for the year ended December 31, 2024. The net cash provided by investing activities for 2025 was primarily attributable to net proceeds of short-term investments of $ 463.9 million, offset by $26.6 million invested in property and equipment. The net cash used in investing activities for 2024 was primary attributable to $ 97.4 million in net purchases of short-term investments as well as $42.9 million in property and equipment.

Financing activities

To date, our primary financing activities have been the sale of equity and the proceeds from long-term loans.

Net cash used in financing activities was $451.3 million for the year ended December 31, 2025 compared to net cash provided by of $90.3 million for the year ended December 31, 2024. The net cash used in financing activities for 2025 was primarily attributable to the repayment of the convertible note at maturity of $560.9 million offset by proceeds of $100 million from the Tranche B Loan of the senior secured term loan credit facility (described below) and $6.1 million in proceeds from the exercise of options and $3.7 million in proceeds from the issuance of shares pursuant to the ESPP. The net cash provided by financing activities for 2024 was primarily attributable to proceeds of $96.9 million from the Tranche A Loan of the senior secured term loan credit facility, offset by a repurchase of the convertible note of $12.9 million. In addition, net cash provided by financing activities in 2024 was attributable to proceeds from the issuance of shares of $4.2 million and the exercise of options by $2.2 million.

Senior Secured Term Loan Credit Facility

On May 1, 2024 Novocure Luxembourg S.a.r.l. ("Borrower"), our wholly-owned subsidiary, entered into a new five-year senior secured credit facility of up to $400.0 million (the "Facility") with BPCR Limited Partnership and BioPharma Credit Investments V (Master) LP (collectively, the "Lenders"), BioPharma Credit PLC, as collateral agent for the Lenders, and the guarantors party to such agreement (the "Loan Agreement"). The Facility may be drawn in up to four drawings. The Loan Agreement provides for an initial term loan in the principal amount of $100.0 million (the "Tranche A Loan"), which was funded to the Borrower on May 1, 2024 (the "Tranche A Funding Date"). Under the Loan Agreement, the Borrower was required to draw $100.0 million on the Facility on or before September 30, 2025 (the "Tranche B Loan"), subject to customary conditions precedent as set forth in the Loan Agreement. Not later than December 31, 2025, the Borrower had the option to draw an additional $100.0 million of the Facility (the "Tranche C Loan") if (i) (A) we received positive results from our PANOVA-3 Phase 3 clinical trial (which we received) or (B) our trailing net revenues for the most recently completed four quarters as reported in our financial statements filed with the U.S. Securities and Exchange Commission ("Trailing Four Quarters of Net Revenue") were greater than $575.0 million and (ii) the Notes were extinguished in full and no longer outstanding. Not later than March 31, 2026, the Borrower has the option to draw an additional $100.0 million of the Facility (the

"Tranche D Loan") if (i) we receive an approval or clearance from the U.S. Food and Drug Administration for our Tumor Treating Fields device for a pancreatic cancer indication or (ii) Trailing Four Quarters of Net Revenue is greater than $625.0 million. The obligations under the Loan Agreement are guaranteed by certain of our subsidiaries and secured by a first lien on the Borrower's and certain of our other subsidiaries’ assets. Outstanding term loans under the Loan Agreement will bear interest at an annual rate equal to 6.25% plus the three-month SOFR (subject to a 3.25% floor), payable quarterly in arrears and calculated on the basis of actual days elapsed in a 360-day year. The Borrower must pay 2.5% of additional consideration on each principal draw, with payment for the Tranche A Loan and the Tranche B Loan paid on the Tranche A Funding Date, and payments for the Tranche C Loan and the Tranche D Loan on their respective funding dates. Principal under the Facility will be repaid in eight equal quarterly repayments commencing with the third quarter of 2027 and continuing each quarter thereafter, with the final payment of outstanding principal due on the fifth anniversary of the Tranche A Funding Date. Voluntary prepayment of all, but not less than all, of the term loans outstanding is permitted at any time, subject to make-whole and prepayment premiums as set forth in the Loan Agreement. Prepayment of all term loans outstanding, subject to make-whole and prepayment premiums, is due and payable upon a change-in-control as defined in the Loan Agreement. Make-whole and prepayment premiums are due and payable for the Tranche B Loans for any voluntary prepayment of the term loans outstanding, upon a change-in-control (as defined in the Loan Agreement), and upon any acceleration of the maturity date, in each case regardless of whether the Tranche B Loan is drawn. The Loan Agreement contains a financial covenant only if the Tranche C Loan and/or Tranche D Loan are funded, in which case we are required to maintain at least Trailing Four Quarters of Net Revenue of at least $500.0 million, calculated on a trailing twelve-month basis as of the end of each fiscal quarter, beginning with the first quarter of 2027 based on year-end 2026 audited financial statements.

The draw of the Tranche B Loan closed on September 26, 2025. As of December 31, 2025 we borrowed the Tranche A Loan and the Tranche B Loan in the aggregate principal amount of $200.0 million. We did not give notice of our intent to borrow the Tranche C Loan. As a result, we no longer have the ability to borrow the Tranche C or Tranche D Loans.

Convertible Notes

On November 5, 2020, we issued $575.0 million aggregate principal amount of 0% Convertible Senior Notes due 2025 (the “Notes”). The net proceeds from the offering were approximately $558.4 million. In June 2024, we redeemed $14.1 million of Notes for cash consideration in financing activities of $12.9 million. In November 2025, we repaid the remaining $560.9 million of the outstanding Notes at maturity.

Overview

We are a global oncology company with a proprietary platform technology called Tumor Treating Fields ("TTFields"), which are electric fields that exert physical forces to kill cancer cells. Our therapy is delivered through a medical device. Our key priorities are to drive commercial adoption of Optune Gio ® , Optune Lua ® , and Optune Pax ® , our commercial TTFields therapy devices, obtain regulatory approval to market TTFields therapy devices in new indications, such as brain metastases from non-small cell lung cancer ("NSCLC"), and to advance clinical and product development programs intended to extend overall survival in some of the most aggressive forms of cancer.

Optune Gio is approved by the U.S. Food and Drug Administration ("FDA") under the Premarket Approval ("PMA") pathway for the treatment of adult patients with newly diagnosed glioblastoma ("GBM") together with temozolomide, a chemotherapy drug, and for adult patients with GBM following confirmed recurrence after chemotherapy as monotherapy treatment. We also have a CE certificate to market Optune Gio for the treatment of GBM in the European Union ("EU"), as well as approval or local registration in the United Kingdom ("UK"), Japan, Canada and certain other countries.

Optune Lua is approved by the FDA under the PMA pathway for the treatment of adult patients with metastatic NSCLC concurrent with PD-1/PD-L1 inhibitors or docetaxel following progression on or after a platinum-based regimen. We also have a CE certificate to market Optune Lua concurrent with PD-1/PD-L1 inhibitors or docetaxel following progression on or after a platinum-based regimen for the treatment of metastatic NSCLC in the EU. In addition, we received regulatory approval for Optune Lua for the treatment of adult patients with unresectable advanced/recurrent NSCLC concurrent with PD-1/PD-L1 inhibitors following progression on or after a platinum-based regimen in Japan.

Optune Lua is also approved by the FDA under the Humanitarian Device Exemption ("HDE") pathway for the treatment of adult patients with malignant pleural mesothelioma or pleural mesothelioma (together, "MPM") together

with standard chemotherapies. We have also have a CE certificate in the EU and approval or local registration to market Optune Lua for the treatment of MPM in certain other countries.

Optune Pax is approved by the FDA under the PMA pathway for the treatment of adult patients with locally advanced pancreatic cancer concurrent with gemcitabine and nab-paclitaxel. We are pursuing regulatory approval to market Optune Pax in other countries.

We market our Products in multiple countries around the globe with the majority of our revenues coming from the use of Optune Gio in the U.S., Germany, France and Japan. We are actively evaluating opportunities to expand access to Optune Gio, Optune Lua and Optune Pax in additional international markets.

We have established coverage policies with both public and private payers for the use of Optune Gio in our active markets. We are actively pursuing coverage policies with payers to expand access to Optune Lua and Optune Pax and in the meantime we will bill and seek reimbursement from payers on an individual case basis, as applicable.

In September 2025, we presented final data from the Phase 3 METIS clinical trial evaluating the use of TTFields therapy and best supportive care (BSC) for the treatment of adult patients (n=298) with 1-10 brain metastases from NSCLC following stereotactic radiosurgery at the 2025 American Society for Radiation Oncology Annual Meeting. The primary endpoint of the METIS trial was defined as the time to intracranial progression (TTIP), as measured from the date of first SRS treatment to intracranial progression or neurological death, whichever occurred first. When accounting for competing risks using the Fine–Gray method, patients treated with TTFields therapy and BSC experienced a 28% lower risk of intracranial progression compared to those receiving BSC alone (HR=0.72, p=0.044). The median time to intracranial progression was 15.0 months in patients treated with TTFields therapy and BSC compared to 7.5 months in patients treated with BSC alone.

In December 2025 we submitted the final module of the PMA, seeking approval under the proposed brand name Optune Mya ® . The PMA has been accepted as filed by the FDA, and is under substantive review.

We believe the physical mode of action behind TTFields therapy and resulting downstream cellular processes initiated by the damaged cells may be broadly applicable to solid tumor cancers. We have several ongoing and recently concluded clinical trials which further explore the use of TTFields therapy, including the Phase 3 TRIDENT and KEYNOTE D58 trials in GBM, Phase 3 LUNAR-2 trial in NSCLC, and Phase 2 PANOVA-4 trial in pancreatic cancer.

The table below presents the current status of the ongoing clinical trials in our pipeline and anticipated timing of data.

We have several product development programs underway that are designed to optimize the delivery of TTFields to the target tumor and enhance patient ease of use. Our intellectual property portfolio contains hundreds of issued patents and numerous patent applications pending worldwide. We believe we possess global commercialization rights to our Products in oncology and are well-positioned to extend those rights into the future as we continue to find innovative ways to improve our Products.

In 2018, we granted Zai Lab (Shanghai) Co., Ltd. ("Zai") a license to commercialize our Products in China, Hong Kong, Macau and Taiwan ("Greater China") under a License and Collaboration Agreement (the "Zai Agreement"). The Zai Agreement also establishes a development partnership intended to accelerate the development of TTFields therapy in multiple solid tumor cancer indications. For additional information, see Note 12 to the Consolidated Financial Statements.

Impact of Current Events

Conflict in Israel

Since October 2023, the State of Israel has been in a state of war. As of the date of this filing, we believe that there is no immediate risk to our business facilities or operations. Our supply chain teams have increased stock levels to mitigate distribution and service risks from our suppliers in Israel, some of whom are single-source suppliers. Pursuant to our policy to seek and maintain second-source suppliers wherever possible, we are in the process of obtaining second-source suppliers outside of Israel when feasible; however we can provide no assurance that we will secure or maintain such suppliers on a timely basis. Where second-sources suppliers are not reasonably available, we maintain increased inventories to reduce risk.

Recent Changes to U.S. Tariff Rates

Throughout 2025 and 2026, the U.S. has increased or threatened to increase tariff rates on imported goods from numerous countries. The manufacturing of our Products and associated accessories is fully outsourced to third parties across multiple countries. In recent years, in anticipation of active patient growth and new indication launches, we began onboarding additional suppliers and/or supply nodes to increase the resilience of our network. As an example, we are in the final steps of adding production capacity in Mexico and Ireland. This also helps us provide optionality around supply routes to optimize our cost structure, including the emerging tariff landscape. Our current analysis of the global tariff environment leads us to believe there should not be a material impact to gross margins in the short-term and we are actively working to mitigate any potential impacts in the medium to long-term.

We anticipate continued volatility in the global tariff environment through 2026 and we cannot be assured that we will not ultimately be negatively impacted further by these changes.

We view our operations and manage our business in one operating segment. Our net revenues were $655.4 million for the year ended December 31, 2025, $605.2 million for the year ended December 31, 2024 and $509.3 million for the year ended December 31, 2023. Our net loss was $136.2 million for the year ended December 31, 2025, net loss was $168.6 million for the year ended December 31, 2024 and net loss was $207.0 million for the year ended December 31, 2023. As of December 31, 2025, we had an accumulated deficit of $1,290.4 million.
