We also rely on certain third-party vendors in connection with the analysis we perform to create diagnostic reports for our Zio Services, which is dependent upon a recording made by each Zio System. For long-term continuous monitoring utilizing our Zio XT System, for example, requires the physical return of the Zio XT patch to one of our clinical centers and we predominantly rely on the U.S. Postal Service (“USPS”) to perform this delivery service. Delivery of the Zio XT patch to one of our clinical centers may be subject to disruption to the USPS delivery infrastructure. Further, for the MCT monitoring services utilizing our Zio AT System, we rely on the provision of cellular communication services for the timely transmission of patient information and reportable events. The reliability of the electronic communication and cloud services required for these operations are subject to natural disasters, labor disruptions, human error, and infrastructure failure. Any of these disruptions may render it difficult or temporarily impossible for us to provide some or all our Zio Services and bill for those services, adversely affecting our operating results, causing significant distraction for management, and negatively impacting our business reputation. We also expect that our reliance on third-party vendors will increase as our business grows, exposing us to increased harm if such disruptions occur.

Our ~~revenue relies substantially~~ability to compete depends on our ability to innovate successfully.

The market for medical devices, including the remote cardiac monitoring segment, is competitive, dynamic, and marked by rapid and substantial technological development and product innovation. While there are barriers that would challenge new entrants or existing competitors from developing products that compete directly with the devices used in our Zio ~~service, which is currently our only offering. If the Zio service or future product offerings fail to gain, or lose, market acceptance, our business will suffer.~~

Our current revenue is dependent on orders for the Zio service, and we expect that reimbursement for the Zio service will account for substantially all of our revenue for the foreseeable future. We are in various stages of research and development for other diagnostic screening solutions and new indicationsServices, these barriers can be overcome.

Any new products may not be accepted~~technologies offered by physicians or may merely replace revenue generated by our Zio service and not generate additional revenue. If we have difficulty launching new products, our reputation may be harmed and our financial results adversely affected. In order to substantially increase our revenue, we will need to target physicians other than cardiologists, such as emergency room doctors, primary care physicians, and other physicians with whom we have had little contact and who may require a different type of selling effort.competitors. If we are unable to ~~increase orders for the Zio service, expand reimbursement for the Zio service, or~~innovate successfully, ~~develop and commercialize new products and services, our revenue and our ability to achieve and sustain profitability would be impaired.~~

~~Our quarterly and annual results may fluctuate significantly and may not fully reflect the underlying performance of our business.~~

Our quarterly and annual results of operations, including our revenue, profitability and cash flow, may vary significantly in the future and period-to-period comparisons of our operating results may not be meaningful. Accordingly, the results of any one quarter or period should not be relied upon as an indication of future performance. Our quarterly and annual financial results may fluctuate as a result of a variety of factors, many of which are outside our control and, as a result, may not fully reflect the underlying performance of our business. Fluctuation in quarterly and annual results may decrease the value of our common stock. Factors that may cause fluctuations in our quarterly and annual results include, without limitation:

•~~market awareness and acceptance of the Zio service;~~

•~~our ability to get payors under contract at acceptable reimbursement rates;~~

•~~the availability of reimbursement for the Zio service at acceptable rates through government programs;~~

•~~our ability to attract new customers and improve our business with existing customers;~~

•~~results and interpretations of clinical trials providing data relevant to the Zio service, whether conducted by us, competitors or third parties;~~

•the timing and success of new product introductions or product improvements by us or our competitors or any other change in the competitive dynamics of our industry, including consolidation among competitors, customers or strategic partners;

•~~the amount and timing of costs and expenses related to the maintenance and expansion of our business and operations;~~

•~~changes in our pricing policies or those of our competitors;~~

•~~general economic, industry and market conditions;~~

•~~the impact of the COVID-19 pandemic on our operations and financial results;~~

•~~the regulatory environment;~~

•~~expenses or loss of sales associated with unforeseen product quality issues;~~

•~~timing of physician orders and demand for our Zio service;~~

•seasonality factors, such as patient and physician vacation schedules, severe weather conditions, and insurance deductibles, that hamper or otherwise restrict when a patient seeking diagnostic services such as the Zio service visits the ordering physician;

•the hiring, training, and retention of key employees, including our ability to expand our sales team and clinical operations team and to expand and coordinate our compliance training efforts in tandem;

•~~litigation or other claims against us for intellectual property infringement or otherwise;~~

•~~our ability to obtain additional financing as necessary; and~~

•~~advances and trends in new technologies and industry standards.~~

Because our quarterly results may fluctuate, period-to-period comparisons may not be the best indication of the underlying results of our business and should only be relied upon as one factor in determining how our business is performing.

~~We have noticed seasonality in the use of our Zio service which, along with other factors such as severe weather, may cause quarterly fluctuations in our revenue.~~

During the summer months and the holiday seasons, we have observed that the use of our Zio service decreases, which reduces our revenue during those periods. We believe that the decrease in orders may result from physicians or their patients taking vacations. Certain weather conditions, including natural disasters, may also hamper or otherwise impact visits to ordering physicians or prevent patients from seeking diagnostic services, such as the Zio service. Similarly, we generally experience some effects of seasonality due to the renewal of insurance deductibles at the beginning of the calendar year. These factors may cause our results of operations to vary from quarter to quarter.

Reimbursement by CMS is highly regulated and subject to change; our failure to comply with applicable regulations could result in decreased revenue and may subject us to penalties or have an adverse impact on our business.

For the six months ended June 30, 2022, we received approximately 23% of our revenue from reimbursement for our Zio service by CMS. Under CMS guidelines for participation in the Medicare program CMS designates us as an IDTF. CMS imposes extensive and detailed requirements on IDTFs, including but not limited to: rules that govern how we structure our relationships with physicians, how and when we submit reimbursement claims, how we operate our monitoring facilities, and how and where we provide our monitoring services. Our failure to comply with applicable CMS rules could result in a discontinuation of our reimbursement under the CMS payment programs, our being required to return funds already paid to us, civil monetary penalties, criminal penalties and/or exclusion from CMS programs.

~~Changes in federal health care program coverage and CMS reimbursement rates for the Zio service could affect the adoption and profitability of our Zio service.~~

Government payors may change their coverage and reimbursement policies, as well as payment amounts, in a way that would prevent or limit reimbursement for our Zio service, which would significantly harm our business. Government and other third-party payors require us to report the service for which we are seeking reimbursement by using a Current Procedural Terminology (“CPT”) code-set maintained by the American Medical Association (“AMA”). For Zio XT, we had historically utilized temporary CPT codes (or Category III CPT codes), used for newly introduced technologies specific to our category of diagnostic monitoring. The process to convert temporary Category III CPT codes to permanent Category I CPT codes is governed by the AMA and CMS.

Determinations of which products or services will be eligible for reimbursement by Medicare can be developed at the national level through a national coverage determination (“NCD”) issued by CMS or at the local level through a local coverage determination (“LCD”), issued by one or more of the regional Medicare Administrative Contractors (“MACs”), who are private contractors that process and pay claims on behalf of CMS for different geographic regions. In the absence of a specific NCD, as has historically been the case with the Zio XT service, the MAC with jurisdiction over a specific geographic region will have the discretion to issue an LCD. Our Zio service may be eligible for reimbursement at the rates set by the regional MACs until CMS establishes national payment rates for the CPT codes that we use to seek reimbursement for the Zio XT service.

On October 25, 2019, the AMA’s CPT Editorial Panel established eight new Category I CPT codes that are applicable to the Zio XT service and took effect on January 1, 2021. Category I CPT codes 93241 through 93248 are split between two sets of four codes with rates tied to those codes for (i) wear-time of greater than 48 hours and up to 7 days, and (ii) greater than 7 days and up to 15 days. We primarily rely on CPT codes 93247 (for wear-time of greater than 7 days and up to 15 days) and 93243 (for wear-time of greater than 48 hours and up to 7 days) to seek reimbursement for our Zio XT service. In November 2021, CMS published the Calendar Year 2022 Medicare Physician Fee Schedule Final Rule (the “2022 Final Rule”). In the 2022 Final Rule, CMS did not establish national pricing for Calendar Year 2022 for Category I CPT codes 93241, 93243, 93245 and 93247, which include the two CPT codes upon which we primarily rely for our Zio XT service. Instead, CMS designated these for contractor pricing in Calendar Year 2022, which meant that prices would be set regionally by each MAC.

In January 2022, Novitas Solutions, the MAC which covers the region where our IDTF in Houston, Texas is located, updated reimbursement rates for CPT codes 93243 and 93247 for its jurisdiction to $223 and $233, respectively. These updated rates were retroactive to January 1, 2022. These rates were higher than the rates posted by Novitas in 2021, but continue to be significantly below historical Medicare rates for our Zio XT service. In April 2022, NGS, the MAC which covers the region where our IDTF in Deerfield, Illinois is located, updated reimbursement rates for CPT codes 93243 and 93247 for its jurisdiction to $335 and $347, respectively. These updated rates were retroactive to January 1, 2022. These rates are higher than the historical Medicare rates for our Zio XT service.

In July 2022, CMS published its Calendar Year 2023 Medicare Physician Fee Schedule Proposed Rule (the “2023 Proposed Rule”). In the 2023 Proposed Rule, CMS proposed national payment rates for the Category I CPT codes that we primarily use to seek reimbursement for our Zio XT service. In the 2023 Proposed Rule, CMS proposed relative value units for CPT codes 93247 and 93243 and a Calendar Year 2023 "Conversion Factor" which we interpret, collectively with the Medicare payment reduction (sequestration) and the sequestration under the Statutory Pay-As-You-Go Act of 2010, to imply national payment rates of $215 and $204 for CPT codes 93247 and 93243 codes, respectively. Based on the proposed Calendar Year 2023 Geographic Practice Cost Index (“GPCI”) modifiers applicable to the locations of our Medicare-enrolled IDTFs in Deerfield, Illinois, Houston, Texas, and San Francisco, California, we estimate the applicable payment rates could range from $218 to $295 for CPT code 93247 and $207 to $280 for CPT code 93243.

The 2023 Final Rule is expected to be announced by November 2022 for implementation on January 1, 2023. It is possible that CMS will adopt a lower national rate, a higher national rate, or continue applying contractor pricing.

We remain engaged with CMS and all of the MACs, and are working with other industry participants to submit additional cost data on long-term ECG monitoring for consideration to establish appropriate national or local rates. We cannot provide certainty at this time on the potential outcome of the discussions with the CMS or MACs or on the timing of any action to be taken.

Given the evolving nature of the healthcare industry and ongoing healthcare cost reforms, we are and will continue to be subject to changes to the level of Medicare coverage and reimbursement for our Zio service, and unfavorable coverage determinations at the national or local level could adversely affect our business and results of operations.

Further, a reduction in coverage by Medicare could cause some commercial third-party payors to implement similar reductions in their coverage or level of reimbursement of the Zio service. Although a large majority of commercial customers have re-contracted the Zio XT service at pre-existing rates since the establishment of the Category I codes on January 1, 2021, if we are unsuccessful in improving the Medicare rates, we believe that commercial rates may begin to be more negatively impacted.

As a result of the CPT code changes that took effect January 1, 2021, the number of claims from the first half of 2021, which contained differences between the submitted price and reimbursement rate and overall denials, increased significantly compared to our historical experience as a result of CPT code transition issues with the payors. We continue to work with the payors to collect on these claims, however, the collection cycle for these claims is significantly longer than usual and may lead to higher write-offs of doubtful accounts for those periods and negatively impact our results of operations.

If we are unable to achieve a level of revenues adequate to support our cost structure, or are unable to reduce our overall cost structure, this would raise substantial doubts about our ability to continue as a going concern.

Controls imposed by CMS and commercial third-party payors designed to reduce costs, commonly referred to as “utilization review,” may affect our operations. Federal law contains numerous provisions designed to ensure that services rendered to CMS patients meet professionally recognized standards and are medically necessary, appropriate for the specific patient, and cost-effective. These provisions include a requirement that a sampling of CMS patients must be reviewed by quality improvement organizations, which review the appropriateness of orders for services, the quality of care provided, and the appropriateness of reimbursement costs. Quality improvement organizations may deny payment for services or assess fines, and also have the authority to recommend to the U.S. Department of Health and Human Services, that a provider in substantial noncompliance with the standards of the quality improvement organization be excluded from participation in the Medicare program. The Patient Protection and Affordable Care Act, as amended by the Health Care and Education Affordability Reconciliation Act (the “Affordable Care Act”), potentially expands the use of prepayment review by Medicare contractors by eliminating statutory restrictions on their use and, as a result, efforts to impose more stringent cost controls are expected to continue. Utilization review is also a requirement of most non-governmental managed care organizations and other third-party payors. To date these controls have not had a significant effect on our operations, but significant limits on the scope of services reimbursed and on reimbursement rates and fees could have a material, adverse effect on our business, financial position, and results of operations in the future.

~~Each state’s Medicaid program has its own coverage determinations related to~~ our services and ~~some state Medicaid programs do not provide their recipients with coverage for~~related devices could become obsolete and our revenue would decline as our customers prescribe or purchase our competitors’ services.

In order to remain competitive, we must continue to develop new product offerings and enhancements to our Zio service. Even if our Zio service is covered by a state Medicaid program, we must be enrolled as a Medicaid provider by the state in which the Medicaid recipient resides in order for us to be reimbursed by a state’s Medicaid program. Even if we are recognized as a provider in a state, Medicare’s rate for our Zio service may be low, and the Medicaid reimbursement amounts are sometimes as low, or lower, than the Medicare reimbursement rate. As a result of all of these factors, our Zio service is not reimbursed or only reimbursed at a very low dollar

amount by many state Medicaid programs; in some cases, a state Medicaid program’s reimbursement rate for our Zio service might be zero dollars. Additionally, certain states may require Medicaid recipients to pay for part of the Zio service, and since the recipients of Medicaid are low-income individuals, we are often unable to collect any amounts directly from individual recipients of the Zio service covered by Medicaid. Low or zero-dollar Medicaid reimbursement rates for our Zio service would have an adverse effect on our business, gross margins, and revenues. Most of the Zio services we provide are reimbursed through Medicare or private third-party payors, not Medicaid, but if that were to change in the future, or the percentage of Zio services provided to Medicaid recipients were to increase, our gross margins would be adversely affected as a result.

Also, healthcare reform legislation or regulation may be proposed or enacted in the future that may adversely affect such policies and amounts. Changes in the healthcare industry directed at controlling healthcare costs or perceived over-utilization of ambulatory cardiac monitoring products and services could reduce the volume of Zio services ordered by physicians. If more healthcare cost controls are broadly instituted throughout the healthcare industry, the volume of cardiac monitoring solutions ordered could decrease, resulting in pricing pressure and declining demand for our Zio service.Services. We cannot predict whether and to what extent existing coverage and reimbursement will continue to be available. If physicians, hospitals, and clinics are unable to obtain adequate coverage and government reimbursement of the Zio service, they are significantly less likely to use the Zio service and our business and operating results would be harmed.

In addition, any changes to, or repeal of, the Affordable Care Act or its implementing regulations may have a material adverse effect on our results of operations. We cannot predict what other healthcare programs and regulations will ultimately be implemented at the federal or state level or the effect of any future legislation or regulation in the United States may have on our business.

If third-party commercial payors do not provide any or adequate reimbursement, including as a result of the CMS and MAC reimbursement rates for our Zio XT service, rescind or modify their reimbursement policies, or delay payments for our Zio service, or if we are unable to successfully negotiate reimbursement contracts, our commercial success could be compromised.

We receive a substantial portion of our revenue from third-party private commercial payors, such as medical insurance companies. These commercial payors may reimburse our Zio service at inadequate rates, suspend or discontinue reimbursement at any time, impose requirements that may result in a greater number of denied claims, or require or increase co-payments from patients. The recent actions taken by CMS and MACs, including Novitas Solutions, to reduce the reimbursement rates for use of the Zio XT service by Medicare patients could influence the price that commercial payors are willing to pay for our Zio service. Contracts with commercial payors, which set forth the Zio XT service reimbursement rates for us and ordering physicians, could be terminated, or payors could seek to renegotiate them at any time to try to obtain pricing at reduced amounts at or near the Novitas Solutions reimbursement rates. Some payors do not have contracts with us, and others that are already in the process of negotiating contracts may look to negotiate lower reimbursement rates for the Zio XT service in response to actions taken by Novitas Solutions. Any such actions could have a significant and adverse effect on our revenue and the revenue of physicians who prescribe our Zio service. Physicians may not order our Zio service unless payors reimburse a substantial portion of the submitted costs, including the physician, hospital, or clinic’s charges related to the application of certain products, including the Zio monitor and the interpretation of results which may inform a diagnosis. Additionally, certain payors may require that physicians order another arrhythmia diagnostic monitoring option prior to ordering the Zio service. There is significant uncertainty concerning third-party reimbursement of any new product or service until a contracted rate is established. Reimbursement by a commercial payor may depend on a number of factors, including, but not limited to, a payor’s determination that the ordered service is:

•~~not experimental or investigational;~~

•~~appropriate for the specific patient;~~

•~~cost effective;~~

•~~supported by peer-reviewed publications; and~~

•~~accepted and used by physicians within their provider network.~~

Since each payor makes its own decision as to whether to establish a policy concerning reimbursement, or enter into a contract with us to set the price of reimbursement, seeking reimbursement on a payor-by-payor basis is a time consuming and costly process to which we dedicate substantial resources. If we do not dedicate sufficient resources to establishing contracts with third-party commercial payors, or do not continue to validate the clinical value of the Zio service through studies and physician adoption, the amount that we are reimbursed for our products may decline, our revenue may become less predictable, and we will need to expend more efforts on a claim-by-claim basis to obtain reimbursement for our products.

A substantial portion of our revenue is derived from third-party commercial payors who have pricing contracts with us, which means that the payor has agreed to a defined reimbursement rate for our services. These contracts provide a high degree of certainty to us, physicians, clinics and hospitals with respect to the rate at which our services will be reimbursed. These contracts also impose a number of obligations regarding billing and other matters, and our noncompliance with a material term of such contracts may result in termination of the contract and loss of any associated revenue. We expect to continue to dedicate resources to maintaining compliance with these pricing contracts, to ensure payors acknowledge and are aware of the clinical and economic value of our services, and the interest on the part of physicians, clinics, and hospitals who use our services and participate in their provider networks. However, we can provide no assurance that we will retain any given contractual payor relationship. A loss of these pricing contracts can increase the uncertainty of reimbursement of claims from third-party payors.

A portion of our revenue is derived from third-party commercial payors without such contracts in place. Without a contracted rate, reimbursement claims for our products are often denied upon submission, and we or our outside billing partner, XIFIN, Inc. (“XIFIN”), must appeal the denial. The appeals process is time-consuming, expensive, and may not result in full payment or any payment at all. In cases where there is no contracted rate for reimbursement it may be more difficult for us to acquire new accounts with physicians, clinics, and hospitals. In addition, in the absence of a contracted rate, there is typically a greater out-of-network, co-insurance or co-payment requirement which may result in payment delays or decreased likelihood of full collection. In some cases involving non-contracted insurance companies, we may not be able to collect any amount or may only be able to collect a portion of the invoiced amount for our services.

~~We expect to continue to dedicate resources to establishing pricing contracts with non-contracted insurance companies; however, we~~ can provide no assurance that we will be successful in ~~obtaining~~fully recognizing the strategic value of our ECG database, expanding the indications for our Zio Services, developing new services and related devices, or commercializing them in ways that achieve market acceptance. In addition, if we develop new services, sales of those services may reduce revenue generated from our existing services. Maintaining adequate research and development personnel and resources to meet the demands of the market is essential. If we are unable to develop new services and related devices, applications, or features, or improve our algorithms due to constraints, such ~~pricing contracts~~as insufficient cash resources, high employee turnover, inability to hire personnel with sufficient technical skills, or a lack of other research and development resources, we may not be able to maintain our competitive position compared to other companies. Furthermore, many of our competitors devote a considerably greater amount of funds to their research and development programs than we do, and those that do not may be acquired by larger companies that would allocate greater resources to research and development programs. Our failure or inability to devote adequate research and development resources or compete effectively with the research and development programs of our competitors could harm our business.

We have entered into a development agreement with a third-party that may not result in the development of commercially viable devices or the generation of significant future revenues. We may explore or enter into other development or collaboration agreements with other third parties, and these similarly may not result in development of commercially viable devices or services or the generation of significant future revenues.

We have entered into the Development Agreement with Verily to develop certain next-generation Afib screening, detection, or monitoring devices to enhance our Zio Services, which involves combining our technology platforms and capabilities with those of Verily. As part of the Development Agreement, we paid Verily an up-front fee of $5.0 million in cash, and through December 31, 2022 and March 31, 2023 , we have achieved milestones and additional related payment obligations totaling $11.0 million. We have agreed to make additional payments over the term of the Development Agreement up to an aggregate of $1.75 million, subject to the achievement of certain development and regulatory milestones. The success of our collaboration with Verily is highly dependent on the efforts provided to the collaboration by Verily and us and the skill sets of our respective employees. Support of these efforts requires significant resources, including research and development, manufacturing, quality assurance, and clinical and regulatory personnel. Even with the FDA’s clearance of our clinically-integrated ZEUS System for the Zio Watch, continued product testing, market research, and related activities may result in a delay to device launch and additional expense associated with any commercialization efforts. Even if and when launched, the developed devices may also not be accepted in the marketplace, and there is no assurance that adequate coverage or reimbursement would be available, or that ~~such pricing contracts~~an alternative payment model can be developed.

After the initial term and scope of the Development Agreement, and in order to commercialize any services in connection with the developed devices with Verily, we will ~~contain reimbursement for our services at appropriate rates. If we fail~~need to ~~establish these contracts,~~enter into a commercialization agreement. There is no guarantee that we will be able to ~~recognize revenue only based~~enter into such an agreement on ~~an estimated average collection rate per historical cash collections.~~commercially reasonable terms or at all. If we are unable to reach agreement with Verily on terms, the up-front fee and regulatory and development milestone payments and our internal development costs would not be recovered and the licenses to use Verily’s technology will expire.

This collaboration may not result in the development of devices, and ultimately services, that achieve commercial success and could be terminated prior to developing any devices. In ~~addition, XIFIN may need to expend significant resources obtaining reimbursement on a claim-by-claim basis and in adjudicating claims which are denied altogether~~the event of any termination or ~~not reimbursed at acceptable rates. We currently pay XIFIN a percentage~~expiration of the ~~amounts~~Development Agreement, we may be required to devote additional resources to device development and we may face increased competition, including from Verily.

Failure~~development of commercially viable products or services or the generation of significant future revenues.

International expansion of our business exposes us to ~~establish contracts~~market, regulatory, political, operational, financial and economic risks associated with doing business outside of the United States.

While we currently derive substantially all of our revenue and maintain substantially all of our assets in the United States, we intend to continue to pursue growth opportunities outside of the United States, especially in the Philippines and the United Kingdom, and we may increase our use of administrative and support functions from locations outside the United States, which could expose us to risks associated with international sales and operations. Additionally, our international expansion efforts may not be successful, we may experience difficulties in scaling these functions from locations outside the United States, and we may not experience the expected cost efficiencies.

Our international operations are, and will continue to be, subject to a number of risks, including:

•multiple, conflicting and changing laws and regulations such as tax laws, privacy laws, export and import restrictions, employment laws, regulatory requirements, and other governmental approvals, permits, and licenses;

•obtaining and sustaining regulatory approvals, certifications, and regulatory compliance where required for the sale of our Zio Services in various countries;

•requirements to maintain data and the processing of that data on servers located within such countries;

•complexities associated with managing multiple payor reimbursement regimes, government payors, or patient self-pay systems;

•logistics and regulations associated with shipping and returning our Zio patches following use;

•limits on our ability to penetrate international markets if we are required to process our Zio Services locally;

•financial risks, such as longer payment cycles, difficulty collecting accounts receivable, the effect of local and regional financial pressures on demand and payment for our services, fluctuations in trade policy and tariff regulations, changes in international tax regulations applicable to our business, and exposure to foreign currency exchange rate fluctuations, which may reduce the reported value of our foreign currency denominated revenues, expenses, and cash flows;

•decreased emphasis or enforcement or intellectual property protections in some countries outside the United States in comparison to that in the United States;

•increased risk of litigation or administrative proceedings in connection with our relationships with international business partners, including litigation against persons whom we believe have infringed on our intellectual property, infringement litigation filed against us, litigation against a competitor, or litigation filed against us by distributors or service providers resulting from a breach of contract or other claim, as well as disputes regarding government and public tenders, any of which may result in substantial costs to us, adverse judgments, settlements, and diversion of our management’s attention;

•natural disasters, political and economic instability, including wars, terrorism, political unrest, outbreak of disease, boycotts, curtailment of trade, and other market restrictions;

•regulatory and compliance risks that relate to maintaining accurate information and control over activities subject to regulation under the FCPA, UK Bribery Act of 2010, and comparable laws and regulations in other countries;

•compliance risks associated with the GDPR (including as it applies in the United Kingdom by virtue of the Data Protection Act 2018), enacted to protect the privacy of all individuals in the European Union and the United Kingdom, and which places certain restrictions on the export of personally identifiable data outside of the European Union or the United Kingdom, as applicable;

•compliance risks associated with the revised regulations in the EU MDR that outline the requirements for medical device CE marking; and

•compliance risks associated with the UK MDR, which replaced the CE marking requirements for medical devices marketed and sold in the United Kingdom with a UKCA mark following the United Kingdom’s withdrawal from the European Union.

Any of these factors could significantly harm our future international expansion and operations and, consequently, our revenue and results of operations.

Exposure to United Kingdom political developments, including the outcome of its withdrawal from membership in the European Union, could be costly and difficult to comply with and could seriously harm our business.

Our operations in the United Kingdom account for approximately 1% of our revenue for the three months ended March 31, 2023 and we intend to continue to pursue growth opportunities in the United Kingdom. There are still a number of areas of uncertainty in connection with the future of the United Kingdom and its relationship with the European Union following the United Kingdom’s exit from the European Union in 2020 (commonly referred to as “Brexit”), including the application and interpretation of the UK-EU trade agreement (the “Trade and Cooperation Agreement”), which went into force in May 2021. For example, because a significant proportion of the regulatory framework in the United Kingdom is currently derived from EU directives and regulations, Brexit could result in material changes to the regulatory regime applicable to many of our current operations. The UK government and the MHRA began undertaking public consultations on the future regulation of medical devices in 2022 and plan to introduce the new regulatory system at the beginning of July 2024. Although the Trade and Cooperation Agreement offers UK and EU companies preferential access to each other’s markets, ensuring imported goods will be free of tariffs and quotas, economic relations between the United Kingdom and the European Union are on more ~~third-party payors~~restricted terms than existed previously. Therefore, at this time, we cannot predict the impact that the Trade and Cooperation Agreement and any future agreements contemplated under the terms of the Trade and Cooperation Agreement will have on our future business efforts to commercialize our Zio Services in the United Kingdom and the European Union. Accordingly, it is possible that the Trade and Cooperation Agreement may adversely affect our operations and financial results.

Our success depends on our ability to ~~increase~~attract and retain senior management and key personnel.

Our success depends on our ~~revenue.~~ability to retain our senior management and to attract and retain qualified personnel in the future. Competition for senior management personnel, as well as salespersons, scientists, clinicians, and engineers, is intense and we may not be able to retain our personnel. The loss of key personnel, including key members of our senior management team or members of our board of directors, as well as certain of our key finance, legal, regulatory, research and development, and clinical personnel, could disrupt our operations and have a material and adverse effect on our ability to grow our business. Each of our officers may terminate their employment at any time without notice and without cause or good reason. The loss of a member of our senior management team or our professional staff would require the remaining executive officers to divert immediate and substantial attention to seeking a replacement.

We have recently experienced significant changes in our executive leadership, including the appointment of Quentin S. Blackford as our President and Chief Executive Officer in October 2021 following the resignation of our prior President and Chief Executive Officer, Kevin King, in January 2021. Douglas Devine, our Chief Operating Officer, and Michael Coyle served as Chief Executive Officer from June 2021 to October 2021 and January 2021 to June 2021, respectively, before Mr. Blackford’s appointment. We have had additional executive officer positions changes during the three months ended March 31, 2023 (including the March 2023 resignation of Douglas Devine as Chief Operating Officer) and may experience further changes in executive leadership in the future.

Changes to strategic or operating goals, which can often times occur with the appointment of new executives, can create uncertainty, may negatively impact our ability to execute quickly and effectively, and may ultimately be unsuccessful. If we do not integrate new executives successfully, we may be unable to manage and grow our business, and our financial condition and profitability may suffer as a result. In addition, a failure to enter into contracts could affect a physician’s willingness to order our services because of the administrative work involved in interacting with patients to answer their questions and help them obtain reimbursement for our services. If physicians are unwilling to order our services due to the ~~lack~~extent we experience additional management turnover, competition for top management is high and it may take months to find a candidate that meets our requirements. If we are unable to attract and retain qualified management personnel, our business could suffer.

Further, we may undertake reorganizations of ~~certainty~~our workforce from time to time, which may result in a temporary reduction in the number of employees in certain locations. We would undertake a reorganization to reduce operating expenses or achieve other business objectives, though we cannot guarantee any specific amount of long-term cost savings. Further, the turnover in our employee base could result in operational and administrative work involved with patients covered by non-contracted insurance companies, or patients covered by non-contracted insurance companies are unwilling to risk that their insurance may charge additional out-of-pocket fees,inefficiencies, which could adversely impact the results of our ~~revenue~~operations, stock price, and customer relationships, and could ~~decline or fail to increase.~~make recruiting for future management and other positions more difficult.

Our continued rapid growth could strain our personnel resources and infrastructure, and if we are unable to manage the anticipated growth of our business, our future revenue and operating results may be harmed.

We have experienced rapid growth in our headcount and in our operations. Any growth that we experience in the future will provide challenges to our organization, requiring us to expand our sales personnel, manufacturing, clinical, customer care, and billing operations and general and administrative infrastructure. In addition to the need to scale our operational and service capacity, future growth will impose significant added responsibilities on management, including the need to identify, recruit, train, and integrate additional employees. Rapid expansion in personnel could impact our capacity to manufacture our Zio ~~monitors,~~patches, market, sell and support our Zio ~~service,~~Services, and analyze the data to produce Zio reports, which could result in inefficiencies and unanticipated costs, impacts to our Zio ~~reports or manufactured devices,~~Services, including our Zio patches, and disruptions to our service operations. Additionally, rapid expansion could require us to rely on overtime to increase capacity that could, in turn, result in greater employee attrition and/or a loss in productivity during the process of recruiting and training additional resources and add to our operating expenses.

As we seek to gain greater efficiency, we may look for ways to expand the automated portion of our Zio ~~service~~Services and require productivity improvements from our ~~certified cardiographic technicians.~~CCTs, within the framework of our wide-ranging regulatory obligations. Such improvements could impact the content of our Zio reports. In addition, rapid and significant growth may strain our administrative and operational infrastructure. Our ability to manage our business and growth will require us to continue to improve our operational, financial, and management controls, reporting systems, and procedures. If we are unable to manage our growth effectively, it may be difficult for us to execute our business strategy and our business could be harmed.

IfFailure to receive the Zio System patches used for the provision of the Zio Services we provide may result in a loss of capital as well as revenue where the receipt of returned devices and processing of data retrieved from returned devices is required to provide our Zio Services.

Our Zio System patches and gateways are provided to patients either (1) during in-office visits with a healthcare provider or (2) remotely via at-home hookup. Although in both scenarios there is the potential that a patient will not return the device(s) at the conclusion of the wear period, home hookups result in a higher likelihood that the patient will fail to return his or her device, which negatively impacts our financial condition when we are unable to ~~support demand~~provide the Zio Services. For example, when the patient returns the Zio XT patch to us at the end of the patient wear period, we provide the Zio XT Services, which include the end of service report based on the data stored on the Zio XT patch, after which we submit a claim to the relevant payor or to the patient for the ~~Zio service or any~~services rendered. If a patient fails to return a device, we experience financial losses, which include the cost of ~~our future products or services, our business could suffer.~~

~~As demand~~the device as well as the loss of potential revenue for the ~~Zio~~ service that is contingent on the returned device for the submission of the associated claim.

Our plans include a high degree of focus on the mSToPs criteria for Afib screening. There are risks that the clinical or ~~any~~payor community will not fully accept these criteria as a basis for selection of patients suitable for screening.

In January 2022, the USPSTF published a recommendation statement on the screening criteria for Afib screening, stating that the current evidence (including the mSToPs study) is insufficient to assess the balance of benefits and harm of Afib screening, and thus found that it could neither recommend for or against screening of adults 50 years or older without a diagnosis or symptoms of Afib and without a history of transient ischemic attack or stroke. In its recommendation, the USPSTF also identified research needs and gaps, including for example assurance that future research involves randomized trials of diverse patient populations and conducting research to optimize the accuracy of screening for Afib. This USPTSF recommendation statement may deter some clinicians or payors from accepting the mSToPs study inclusion and exclusion criteria as a standard for selecting patients for screening for Afib. We cannot predict whether or when the USPSTF’s recommendation on Afib screening will change or be modified based on findings from additional randomized trials, other research or through the continued use of our future products or services increases, we will need to continue to scale our manufacturing capacity and algorithm processing technology, expand customer service, billing, and systems processes, and enhance our internal quality assurance program. We will also need to expand clinical operations, including adding certified cardiographic technicians and other personnel to process higher volumes of data. We cannot assure you that, with any increases in scale, required improvements will be successfully implemented, quality assurance will be maintained, or that appropriate personnel will be available to facilitate growth of our business. Failure to implement necessary procedures, transition to new processes or hire the necessary personnel could result in higher costs of processing data or inability to meet increased demand. There can be no assurance that we will be able to perform our data analysis at a level consistent with demand, quality standards, and physician expectations. If we encounter difficulty meeting market demand, quality standards, or physician expectations, our reputation could be harmed and our future prospects and business could suffer.

~~We plan to introduce new~~ products and services or other similarly situated products and services designed for remote cardiac monitoring.

We may face risks associated with acquisitions of companies, products, and technologies and our business ~~will~~could be harmed if we are ~~not successful in selling these new products and services to our existing customers and new customers~~

We have received FDA clearance for our Zio AT ECG Monitoring System, (“Zio AT”), which is designed to provide timely transmission of data during the wear period. However, we do not yet know whether Zio AT or any other new products and services will be well received and broadly adopted by physicians and their patients or whether sales will be sufficient for us to offset the costs of development, implementation, support, operation, sales, and marketing. Although we have performed extensive testing of our new products and services, their broad-based implementation may require more support than we anticipate, which would further increase our expenses. Additionally, new products and services may subject us to additional risks of product performance, customer complaints, and litigation. If orders of our new products and services are lower than we expect, or if we expend additional resources to fix unforeseen problems and develop modifications, our operating margins are likely to decrease.

We rely on single suppliers for some of the materials used in our products, and if any of those suppliers are unable or unwilling to produce these materials or supply them in the quantities that we need at the quality we require, we may not be able to find replacements or transition to alternative suppliers before our business is materially impacted.

We rely on single suppliers for the supply of our adhesive sub-assembly, disposable plastic housings, instruments and other materials that we use to manufacture and label our Zio monitors. These components and materials are critical and, in some cases, there are relatively few alternative sources of supply. We have not qualified additional suppliers for some of these components and materials and we do not carry a significant inventory of these items. While we believe that alternative sources of supply may be available, we cannot be certain whether they will be available if and when we need them and that any alternative suppliers would be able to provide the quantity and quality of components and materials that we would need to manufacture our Zio monitors if our existing suppliers were unable to satisfy our supply requirements. To utilize other supply sources, we would need to identify and qualify new suppliers to our quality standards, which could result in manufacturing delays and increase our expenses. Any supply interruption, such as those that we have experienced during the COVID-19 pandemic, could limit our ability to manufacture our products and could therefore harm our business, financial condition and results of operations. If our current suppliers and any alternative suppliers do not provide us with the materials we need to manufacture our products or perform our services, if the materials do not meet our quality specifications, or if we cannot obtain acceptable substitute materials, an interruption in our Zio service could occur. Any such interruption may significantly affect our future revenue and harm our relations and reputation with physicians, hospitals, clinics and patients.

If our manufacturing facility becomes damaged or inoperable, or if we are required to vacate the facility, we may be unable to manufacture and ship our Zio monitors, or we may experience delays in production or an increase in costs which could adversely affect our results of operations.

We currently manufacture and assemble the Zio monitors in a single location. Our products are comprise of components sourced from a variety of contract manufacturers, with final assembly completed at our facility in Cypress, California. Our facility and equipment, or those of our suppliers, could be harmed or rendered inoperable by natural or man-made disasters, including fire, earthquake, terrorism, pandemic outbreaks, flooding and power outages. Any ofaddress these may render it difficult or impossible for us to manufacture new products, ship assembled products, and/or receive returned units for some period of time. If our Cypress facility is inoperable for even a short period of time, the inability to manufacture, ship and receive our Zio monitors, and the interruption in research and development of any future products, may result in harm to our reputation, increased costs, the loss of orders and lower revenue. Furthermore, it could be costly and time consuming to repair or replace our facilities and the equipment we use to perform our research and development work and manufacture our products.risks.

If we ~~fail to increase~~are presented with appropriate opportunities, we could acquire or make other investments in complementary companies, products, or technologies. We may not realize the anticipated benefit of our ~~sales~~acquisitions, or the realization of the anticipated benefits may require greater expenditures than anticipated by us. We will likely face risks, uncertainties, and marketing capabilities and develop broad brand awareness in a cost-effective manner, our growth will be impeded, and our business may suffer. However, increasing our sales and marketing efforts may expose us to additional risk from regulators, enforcement authorities, and competitors.

We plan to continue to expand and optimize our sales and marketing infrastructure in order to increase our ordering physician base and our business. Identifying and recruiting qualified personnel and training themdisruptions associated with the integration process, including difficulties in the ~~application~~integration of the operations and services of any acquired company, integration of acquired technology with our Zio ~~service, on compliance with applicable federal and state laws and regulations, and~~Services, including our related internal policies and procedures, requires significant time, expense, and attention. It often takes several months or more before a sales representative is fully trained and productive. Our business may be harmed if our efforts to expand and train our sales force do not generate a corresponding increase in revenue. In particular, if we are unable to hire, develop, and retain talented sales personnel, or if new sales personnel are unable to achieve desired productivity levels in a reasonable period of time, we may not be able to realize the expected benefits of this investment or increase our revenue.

~~Our ability to increase our customer base and achieve broader market acceptance~~Zio Systems, diversion of our ~~products will depend, to a significant extent, on our ability to expand our marketing efforts. We plan to dedicate significant resources to our marketing programs. Our~~management’s attention from other business ~~may be harmed if our marketing efforts and expenditures do not generate a corresponding increase in revenue.~~

~~In addition, we believe that developing and maintaining broad awareness~~concerns, the potential loss of ~~our brand in a cost-effective manner is critical to achieving broad acceptance~~key employees or suppliers of the ~~Zio service~~acquired businesses, and ~~penetrating new accounts. Brand promotion activities may~~impairment charges if future acquisitions are not ~~generate patient or physician awareness or increase revenue, and even if they do, any increase in revenue may not offset the costs and expenses~~as successful as we ~~incur in building our brand.~~originally anticipated. If we fail to successfully ~~promote, maintain, and protect our brand,~~integrate other companies, products or technologies that we may fail to attract or retain the physician acceptance necessary to realize a sufficient return on our brand building efforts, or to achieve the level of brand awareness that is critical for broad adoption of the Zio service.

Our sales and marketing efforts and initiatives may subject us to additional scrutiny of our practices of effective communication of risk information, benefits, or claims under the oversight of the FDA, the Federal Trade Commission (“FTC”), or both agencies. For example, the FDA applies a heightened level of scrutiny to comparative claims when applying its statutory standards for advertising and promotion, including with regard to its requirement that promotional labeling be truthful and not misleading. There is potential for differing interpretations of whether certain communications are consistent with a product’s FDA-required labeling, and FDA will evaluate communications on a fact-specific basis. In addition, making comparative claims may draw scrutiny from our competitors. Where a company makes a claim in advertising or promotion that its product is superior to the product of a competitor (or that the competitor’s product is inferior), this creates a risk of a lawsuit by the competitor under federal and state false advertising or unfair and deceptive trade practices law, and possibly also state libel law. Such a suit may seek injunctive relief against further advertising, a court order directing corrective advertising, and compensatory and punitive damages where permitted by law. If our compliance program and training and monitoring do not effectively keep pace with our sales and marketing growth, we may encounter increased risk in execution of activities by our personnel, potential enforcement and other exposure.

~~Billing for our Zio service is complex, and we must dedicate substantial time and resources to the billing process.~~

Billing for IDTF services is complex, time-consuming and expensive. Depending on the billing arrangement and applicable law, we bill several types of payors, including CMS, third-party commercial payors, healthcare providers, healthcare institutions, and patients, which may have different billing requirements, procedures, or expectations. We also must bill patient co-payments, co-insurance, and deductible amounts. We face risk in our collection efforts, including potential write-offs of doubtful accounts and long collection cycles, which could adversely affectacquire, our business ~~financial condition, and results of operations.~~

~~Several factors make the billing and collection process uncertain, including:~~

•~~differences between the submitted price for our Zio service and the reimbursement rates of payors;~~

•~~compliance with complex federal and state regulations related to billing CMS;~~

•~~differences in coverage among payors and the effect of patient co-payments, co-insurance, and deductible amounts;~~

•~~differences in information and billing requirements among payors; and~~

•~~incorrect or missing patient history, indications, or billing information.~~

As a result of the CPT code changes that took effect January 1, 2021, the number of claims from the first half of 2021 which contained differences between the submitted price and reimbursement and overall denials increased significantly compared to our historical experience as a result of CPT code transition issues with the payors. We continue to work with the payors to collect on these claims and the collection cycle for these claims is significantly longer than usual and may lead to higher write-offs of doubtful accounts for those periods and negatively impact our results of operations.

Additionally, our billing activities require us to implement compliance procedures and oversight, train and monitor our employees, and undertake internal review procedures to evaluate compliance with applicable laws, regulations, and internal policies. Payors also conduct audits to evaluate claims, which may add further cost and uncertainty to the billing process. These billing complexities, and the related uncertainty in obtaining payment for our Zio service, could ~~negatively affect our revenue and cash flow, our ability to achieve profitability, and the consistency and comparability of our results of operations.~~

The operation of our call centers and monitoring facilities is subject to rules and regulations governing IDTFs; failure to comply with these rules could prevent us from receiving reimbursement from CMS and some commercial payors.

~~In order to~~ be enrolled in the Medicare program and reimbursed by CMS under the program, we established an IDTF. An IDTF is a “provider-type” designation under Medicare, defined by CMS as an entity independent of a hospital or physician’s office in which diagnostic tests are performed by licensed, certified, or otherwise qualified nonphysician personnel under appropriate physician supervision. Our IDTFs are staffed by certified cardiographic technicians, who are overseen by a medical director who provides general supervision, including overall direction and control, of the tests performed by our IDTF, but who is not required to be present for tests. The existence of an IDTF allows us to bill a government payor for the Zio service through one or more MACs, such as Novitas Solutions, Noridian Healthcare Solutions, and Palmetto GBA. MACs are companies that operate on behalf of the federal government to process Medicare claims for reimbursement and allow us to obtain reimbursement for our Zio service at CMS or local MAC defined rates. Enrollment as an IDTF requires that we follow strict regulations governing how the center operates, such as requirements regarding the experience and certifications of the cardiographic technicians and supervising physicians. In addition, many commercial payors require our IDTFs to maintain accreditation and certification with the Joint Commission of American Hospitals. To do so we must demonstrate a specified quality standard and are subject to routine inspection and audits. These rules and regulations vary from location to location and are subject to change and differing interpretations. If they change,harmed. Furthermore, we may have to ~~change~~incur debt or issue equity or equity-linked securities to pay for any future acquisitions or investments, the ~~operating procedures at our IDTFs,~~issuance of which could ~~increase~~be dilutive to our ~~costs significantly. If we fail to obtain and maintain IDTF enrollment or accreditation and certification,~~existing stockholders. In addition, our ~~Zio service may no longer be reimbursed by CMS and some commercial payors, which would have a material adverse impact on our business.~~

~~During the second quarter of 2022, we recognized approximately six percent of our revenue from non-contracted third-party payors, and as a result, our quarterly~~ operating results ~~are difficult~~may suffer because of acquisition-related costs, amortization expenses, or charges relating to ~~predict.~~acquired intangible assets.

We have limited visibility as to when we will receive payment for our Zio service with non-contracted payors and we or XIFIN must appeal any negative payment decisions, which often delays collections further. Additionally, a portion of the revenue from non-contracted payors is received from patient co-pays, which we may not receive for several months following delivery of service or may not receive at all. For revenue related to non-contracted payors, we estimate an average collection rate based on factors including historical cash collections. Subsequent adjustments, if applicable, are recorded as an adjustment to revenue. Fluctuations in revenue may make it difficult for us, research analysts, and investors to accurately forecast our revenue and operating results or to assess our actual performance. If our revenue or operating results fall below expectations, the price of our common stock would likely decline.

~~We rely on a third-party billing company, XIFIN, to transmit and pursue claims with payors. A delay in transmitting or pursuing claims could have an adverse effect on our revenue.~~

While we manage the overall processing of claims, we rely on XIFIN to transmit substantially all of our claims to payors and pursue most claim denials. If XIFIN fails to submit claims for our Zio service to payors on a timely basis, if claims are not properly adjudicated upon a denial, or if we are required to switch to a different claims processor, we may experience delays in our ability to process receipt of payments from payors, which would have an adverse effect on our revenue and our business.

The market for ambulatory cardiac monitoring solutions is highly competitive. If our competitors are able to develop or market monitoring products and services that are more effective, or gain greater acceptance in the marketplace, than any products and services we develop, our commercial opportunities will be reduced or eliminated.

The market for ambulatory cardiac monitoring products and services is evolving rapidly and becoming increasingly competitive. Our Zio service competes with a variety of products and services that provide alternatives for ambulatory cardiac

monitoring, including traditional, short-term Holter monitors and event monitors. Our industry is highly fragmented and characterized by a small number of large manufacturers and a large number of smaller regional service providers. These third parties compete with us in marketing to payors and ordering physicians, recruiting and retaining qualified personnel, acquiring technology, and developing products and services that compete with the Zio service. Our ability to compete effectively depends on our ability to distinguish our company and the Zio service from our competitors and their products, and includes such factors as:

•~~safety and effectiveness;~~

•~~acute and long term outcomes;~~

•~~ease of use;~~

•~~price;~~

•~~physician, hospital and clinic acceptance; and~~

•~~third-party reimbursement.~~

Our industry is subject to rapid change and is significantly affected by new product introductions, results of clinical research, corporate combinations, and other factors. Large competitors in the ambulatory cardiac market include companies that sell standard Holter monitors including GE Healthcare, Philips Healthcare, Mortara Instrument, Inc., Spacelabs Healthcare Inc. and Welch Allyn Holdings, Inc., (acquired by Hill-Rom Holdings, Inc.). Additional competitors, such as BioTelemetry, Inc. (acquired by Royal Philips), Preventice Solutions, Inc., (acquired by Boston Scientific, Inc.) and Bardy Diagnostics, Inc., (acquired by Hill-Rom Holdings, Inc. which was acquired by Baxter International, Inc.) offer ambulatory cardiac monitoring services and also function as service providers. These companies have also developed other patch-based cardiac monitors that have received FDA and foreign regulatory clearances. There are also several small start-up companies trying to compete in the patch-based cardiac monitoring space, as well as several entering the patch-based cardiac monitoring market. Large medical device companies may continue to acquire or form alliances with these smaller companies in order to diversify their product offering and participate in the digital health space.

We have seen a trend in the market for large medical device companies to acquire, invest in, or form alliances with these smaller companies in order to diversify their product offerings and participate in the digital health space. Future competition could come from makers of wearable fitness products or large information technology companies focused on improving healthcare. For example, Apple Inc. has added capabilities on its watch platform to measure non-continuous ECG and to alert users to the potential presence of irregular heartbeats suggestive of asymptomatic AF. These competitors and potential competitors may introduce new products and services that more directly compete with our Zio service. Recently, there has been increased acquisition activity and consolidation in our industry. Many of our competitors and potential competitors have significantly greater financial and other resources than we do and have well-established reputations, broader product offerings, and worldwide distribution channels that are significantly larger and more effective than ours. If our competitors and potential competitors are better able to develop new ambulatory cardiac monitoring solutions than us, or develop more effective or less expensive cardiac monitoring solutions, they may render our current Zio service obsolete or non-competitive. Competitors may also be able to deploy larger or more effective sales and marketing resources than we currently have. Competition with these companies could result in price cutting, reduced profit margins, and loss of market share, any of which would harm our business, financial condition and results of operations.

In a competitive environment, a company’s communications may also be subject to heightened scrutiny from regulators and competitors. Our communications are subject to compliance with laws, regulations, and guidance regarding promotional communications, including advertising and promotional labeling, and non-promotional communications, including certain educational and scientific exchanges. We are also subject to potential actions under federal law, including the Lanham Act, and congruous state law, which are designed to protect businesses against the unfair competition of misleading advertising or labeling.

~~Our ability to compete depends on our ability to innovate successfully.~~

The market for medical devices, including the ambulatory cardiac monitoring segment, is competitive, dynamic, and marked by rapid and substantial technological development and product innovation. While there are barriers that would challenge new entrants or existing competitors from developing products that compete directly with ours, these barriers can be overcome. Demand for the Zio service and future related products or services could be diminished by equivalent or superior products and technologies offered by competitors. If we are unable to innovate successfully, our products and services could become obsolete and our revenue would decline as our customers purchase our competitors’ products and services.

In order to remain competitive, we must continue to develop new product offerings and enhancements to the Zio service. We can provide no assurance that we will be successful in fully recognizing the strategic value of our ECG database, expanding the indications for our Zio service, developing new products, or commercializing them in ways that achieve market acceptance. In addition, if we develop new products, sales of those products may reduce revenue generated from our existing products. Maintaining adequate research and development personnel and resources to meet the demands of the market is essential. If we are unable to develop new products, applications, or features, or improve our algorithms due to constraints, such as insufficient cash resources, high employee turnover, inability to hire personnel with sufficient technical skills, or a lack of other research and development resources, we may not be able to maintain our competitive position compared to other companies. Furthermore, many of our competitors devote a considerably greater amount of funds to their research and development programs than we do, and those that do not may be acquired by larger companies that would allocate greater resources to research and development programs. Our failure or inability to devote adequate research and development resources or compete effectively with the research and development programs of our competitors could harm our business.

~~We have entered into a development agreement with a third-party that may not result in the development of commercially viable products or the generation of significant future revenues.~~

We have entered into a development agreement with Verily Life Sciences LLC (an Alphabet Company, referred to as “Verily”) to develop certain next-generation AF screening, detection, or monitoring products, which involve combining Verily and our technology platforms and capabilities (the “Development Agreement”). As part of the Development Agreement, we paid Verily an up-front fee of $5.0 million in cash, and through June 30, 2022, we have achieved milestones and additional related payment obligations totaling $11.0 million. We have agreed to make additional payments over the term of the Development Agreement up to an aggregate of $1.75 million, subject to the achievement of certain development and regulatory milestones. The success of our collaboration with Verily is highly dependent on the efforts provided to the collaboration by Verily and us and the skill sets of our respective employees. Support of these development efforts requires significant resources, including research and development, manufacturing, quality assurance, and clinical and regulatory personnel. Even if our development and clinical trial efforts succeed, the FDA may not clear the developed products or may require additional product testing and clinical trials before clearing the developed products, which would result in product launch delays and additional expense. If cleared by the FDA, the developed products may not be accepted in the marketplace, and there is no assurance that adequate reimbursement will be available, or that an alternative payment model can be developed.

After the initial term and scope of the Development Agreement, and in order to commercialize any developed products with Verily, we will need to enter into a commercialization agreement. There is no guarantee that we will be able to enter into such an agreement on commercially reasonable terms or at all. If we are unable to reach agreement with Verily on terms, the up-front fee and regulatory and development milestone payments and our internal development costs would not be recovered and the licenses to use Verily’s technology will expire.

This collaboration may not result in the development of products that achieve commercial success and could be terminated prior to developing any products. In the event of any termination or expiration of the Development Agreement, we may be required to devote additional resources to product development and we may face increased competition, including from Verily. Verily may use the experience and insights it develops in the course of the collaboration with us to initiate or accelerate their development of products that compete with our products, which may create competitive disadvantages for us. Accordingly, we cannot provide assurance that our collaboration with Verily or any other third party will result in the successful development of commercially viable products or result in significant additional future revenues for our company.

The continuing clinical acceptance of the Zio service depends upon maintaining strong working relationships with physicians. These relationships are subject to a high degree of scrutiny by government regulators and enforcement bodies.

The development, marketing, and ordering of the Zio service depends upon our ability to maintain strong working relationships with physicians and other key opinion leaders. We rely on these professionals’ knowledge and experience for the development and marketing of our Zio service. Among other things, physicians assist us in clinical trials and product development matters and provide public presentations at trade conferences regarding the Zio service. If we cannot maintain our strong working relationships with these professionals and continue to receive their advice and input, the development and marketing of the Zio service could suffer, which could harm our business, financial condition, and results of operations.

At the same time, the medical device industry’s relationship with physicians is under increasing scrutiny by the Health and Human Services Office of the Inspector General (“OIG”), the Department of Justice (“DOJ”), state attorneys general, and other foreign and domestic government agencies. Our failure to comply with laws, rules, and regulations governing our relationships

~~with physicians, or an investigation into our compliance by the OIG, DOJ, state attorneys general, or other government agencies, could significantly harm our business.~~

~~We have a significant amount of debt, which may affect our ability to operate our business and secure additional financing in the future.~~

As of June 30, 2022, we had $34.9 million outstanding under our term loan provided by of our loan agreement with Silicon Valley Bank (“SVB”). We must make significant annual debt payments under the loan agreement which will divert resources from other activities. Our debt with SVB is collateralized by substantially all of our assets and contains customary financial and operating covenants limiting our ability to, among other things, dispose of assets, undergo a change in control, merge or consolidate, enter into certain transactions with affiliates, make acquisitions, incur debt, incur liens, pay dividends, repurchase stock and make investments, in each case subject to certain exceptions. The covenants in the loan agreement, as well as in any future financing agreements into which we may enter, may restrict our ability to finance our operations and engage in, expand or otherwise pursue our business activities and strategies. Our ability to comply with these covenants may be affected by events beyond our control and future breaches of any of these covenants could result in a default under the loan agreement. If not waived, future defaults could cause all of the outstanding indebtedness under the loan agreement to become immediately due and payable and terminate commitments to extend further credit. If we do not have or are unable to generate sufficient cash available to repay our debt obligations when they become due and payable, either upon maturity or in the event of a default, we may not be able to obtain additional debt or equity financing on favorable terms, if at all, which may negatively impact our ability to operate and continue our business as a going concern.

We are also exposed to the risk that our earnings and cash flows could be adversely impacted by fluctuations in interest rates. Our policy is to manage interest costs using the mix of fixed- and floating-rate debt, which we cannot guarantee will mitigate the risk of interest rate fluctuation.

We have recently experienced, and may continue to experience, inflationary costs and pressures, which could increase our costs and operating expenses and have a material adverse impact on our results of operations if we are unable to sufficiently reduce our expenses or offset rising costs.

We have recently experienced and may continue to experience rising costs due to inflation. We continue to monitor the effects of inflationary factors, such as increases in our cost of goods sold and selling and operating expenses, which may adversely affect our results of operations. Specifically, we have experienced inflationary costs affecting the cost of goods, including materials and the components for our Zio service, and have experienced inflationary pressure to increase the wages that we pay our employees, due to challenging labor market conditions. Competitive and regulatory conditions may restrict our ability to fully recover these costs through price increases. As a result, it may be difficult to fully offset the impact of persistent inflation. Our inability or failure to do so could have a material adverse effect on our business, financial condition, cash flow and results of operations or cause us to need to obtain additional capital in future earlier than anticipated.

~~We have recently experienced management turnover, which creates uncertainties and could harm our business.~~

We have recently experienced significant changes in our executive leadership. Quentin S. Blackford has served as our President and Chief Executive Officer since October 2021. Prior to that, Douglas Devine served as Interim Chief Executive Officer, in addition to his other roles, from June 2021 to October 2021 and Michael Coyle served as Chief Executive Officer from January 2021 to June 2021. Additionally, in March 2022, Kevin King, who was our President and Chief Executive Officer from July 2012 to January 2021, announced his resignation from the Board and is no longer a consultant to the Company.

Additionally, in June 2022, Judith Lenane retired from her position as the Company's Executive Vice President, Chief Clinical Officer, and Mintu Turakhia, M.D. M.A.S. was appointed as the Company's Chief Medical Officer and Chief Scientific Officer. In July 2022, David Vort resigned from his position as Executive Vice President, Chief Commercial Officer and Chad Patterson was hired to fill that position. Also in July 2022, we announced the expected appointment of Brice Bobzien as the Company's Chief Financial Officer and Reyna Fernandez as the Company's Executive Vice President, Chief Human Resources Officer. In connection with Brice Bobzien’s appointment, Douglas Devine agreed to resign from his position as Chief Financial Officer of the Company, but will remain the Company’s Chief Operating Officer.

Changes to strategic or operating goals, which can often times occur with the appointment of new executives, can create uncertainty, may negatively impact our ability to execute quickly and effectively, and may ultimately be unsuccessful. In addition, executive leadership transition periods are often difficult as the new executives gain detailed knowledge of our operations, and friction can result from changes in strategy and management style. Management turnover inherently causes some loss of institutional knowledge, which can negatively affect strategy and execution. If we do not integrate new executives successfully, we may be unable to manage and grow our business, and our financial condition and profitability may suffer as a

result. In addition, to the extent we experience additional management turnover, competition for top management is high and it may take months to find a candidate that meets our requirements. If the employees noted above or other members of our management team left, other employees may follow them for new positions and those departures could harm our company as a result. If we are unable to attract and retain qualified management personnel, our business could suffer.

~~We depend on our senior management team and the loss of one or more key employees or an inability to attract and retain highly skilled employees could harm our business.~~

Our success depends largely on the continued services of key members of our executive management team and others in key management positions. For example, the services of Quentin S. Blackford, our President and Chief Executive Officer, and Douglas J. Devine, our Chief Financial Officer and Chief Operating Officer, are essential to formulating and executing on corporate strategy and to ensuring the continued operations and integrity of financial reporting within our company. The services of Patrick Murphy, our Chief Legal Counsel and EVP, Quality, Regulatory, Market Access & Government Affairs, are critical for managing our legal, regulatory, quality, market access and government affairs functions. The services of Mark Day, our Chief Technology Officer, are critical for managing our research and development functions. Our employees may terminate their employment with us at any time. If we lose one or more key employees, we may experience difficulties in competing effectively, developing our technologies and implementing our business strategy. We do not currently maintain key person life insurance policies on these or any of our employees.

In addition, research and development, manufacturing operations, and clinical operations depend on our ability to attract and retain highly skilled personnel, including engineers and certified cardiographic technicians. We may not be able to attract or retain highly qualified personnel, including engineers and certified cardiographic technicians in the future due to the competition for qualified personnel. We have from time to time experienced, and we expect to continue to experience, difficulty in hiring and retaining employees with appropriate qualifications. Many of the companies with which we compete for experienced personnel have greater resources than us. If we hire employees from competitors or other companies, their former employers may attempt to assert that these employees or we have breached legal obligations, resulting in a diversion of our time and resources and, potentially, damages. In addition, job candidates and existing employees, particularly in the San Francisco Bay Area, often consider the value of the stock awards they receive in connection with their employment. If the perceived value of our stock awards declines, it may harm our ability to recruit and retain highly skilled employees. If we fail to attract new personnel or fail to retain and motivate our current personnel, our business and future growth prospects would be harmed.

~~International expansion of our business exposes us to market, regulatory, political, operational, financial and economic risks associated with doing business outside of the United States.~~

~~Our business strategy includes international expansion. Doing business internationally involves a number of risks, including:~~

•multiple, conflicting and changing laws and regulations such as tax laws, privacy laws, export and import restrictions, employment laws, regulatory requirements and other governmental approvals, permits and licenses;

•~~obtaining and sustaining regulatory approvals, certifications, and regulatory compliance where required for the sale of our products and services in various countries;~~

•~~requirements to maintain data and the processing of that data on servers located within such countries;~~

•~~complexities associated with managing multiple payor reimbursement regimes, government payors or patient self-pay systems;~~

•~~logistics and regulations associated with shipping and returning our Zio monitors following use;~~

•~~limits on our ability to penetrate international markets if we are required to process the Zio service locally;~~

•~~natural disasters, political and economic instability, including wars, terrorism, political unrest, outbreak of disease, boycotts, curtailment of trade and other market restrictions;~~

•regulatory and compliance risks that relate to maintaining accurate information and control over activities subject to regulation under the United States Foreign Corrupt Practices Act of 1977 (“FCPA”), U.K. Bribery Act of 2010 and comparable laws and regulations in other countries;

•compliance risks associated with the General Data Protection Regulation (“GDPR”) (including as it applies in the United Kingdom by virtue of the Data Protection Act 2018), enacted to protect the privacy of all individuals in the European Union and the United Kingdom, and places certain restrictions on the export of personally identifiable data outside of the European Union or the United Kingdom, as applicable;

•~~compliance risks associated with the revised regulations in the European Union under the Medical Device Regulations ("EU MDR") that outline the requirements for medical device CE marketing; and~~

•compliance risks associated with the United Kingdom's Medical Device Regulations, which replaced the CE Marking requirements for medical devices marketed and sold in the United Kingdom with a UK Conformity Assessment ("UKCA") mark following the United Kingdom's withdrawal from the European Union.

~~Any of these factors could significantly harm our future international expansion and operations and, consequently, our revenue and results of operations.~~

~~Our relationships with business partners in new international markets may subject us to an increased risk of litigation.~~

As we expand our business internationally, if we cannot successfully manage the unique challenges presented by international markets and our relationships with new business partners within those markets, our expansion activities may be adversely affected and we may become subject to an increased risk of litigation.

We may become involved in disputes relating to our products, contracts and business relationships. Such disputes include litigation against persons whom we believe have infringed on our intellectual property, infringement litigation filed against us, litigation against a competitor or litigation filed against us by distributors or service providers resulting from a breach of contract or other claim. Any of these disputes may result in substantial costs to us, judgments, settlements and diversion of our management’s attention, which could adversely affect our business, financial condition or operating results. There is also a risk of adverse judgments, as the outcome of litigation in foreign jurisdictions can be inherently uncertain.

~~We could be adversely affected by violations of the FCPA, and similar worldwide anti-bribery laws which could have a material adverse effect on our business.~~

The FCPA and similar worldwide anti-bribery laws generally prohibit companies and their intermediaries from corruptly providing any benefits to government officials for the purpose of obtaining or retaining business. We are in the process of designing and implementing policies and procedures intended to help ensure compliance with these laws. In the future, we may operate in parts of the world that have experienced governmental corruption to some degree. We cannot assure you that our internal control policies and procedures will protect us from improper acts committed by our employees or agents. Violations of these laws, or allegations of such violations, could disrupt our business and have a material adverse effect on our business and operations.

In addition, the DOJ or other governmental agencies could impose a broad range of civil and criminal sanctions under the FCPA and other laws and regulations including, but not limited to, injunctive relief, disgorgement, fines, penalties, modifications to business practices including the termination or modification of existing business relationships, the imposition of compliance programs and the retention of a monitor to oversee compliance with the FCPA. The imposition of any of these sanctions or remedial measures could have a material adverse effect on our business and results of operations.

Our proprietary data analytics engine may not operate properly, which could damage our reputation, give rise to claims against us, or divert application of our resources from other purposes, any of which could harm our business and operating results.

The ECG data that is gathered through our Zio monitors is curated by algorithms that are part of our Zio service, and a Zio report is delivered to the ordering physician for interpretation and diagnosis. The continuous development, maintenance, and operation of our deep-learned backend data analytics engine is expensive and complex, and may involve unforeseen difficulties including material performance problems, undetected defects, or errors. We may encounter technical obstacles, and it is possible that we may discover additional problems that prevent our proprietary algorithms from operating properly. We may also attempt to develop new capabilities and incorporate new technologies, including artificial intelligence, which could impact our data analytics platform’s performance. If our data analytics platform does not function reliably or fails to meet physician or payor expectations in terms of performance, physicians may stop prescribing the Zio service and payors could attempt to cancel their contracts with us.

Any unforeseen difficulties we encounter in our existing or new software, cloud-based applications, telecommunication service providers, and analytics services, and any failure by us to identify and address them, could result in loss of revenue or market share, diversion of development resources, injury to our reputation, and increased service and maintenance costs. Correction of defects or errors could prove to be impossible or impracticable. The costs incurred in correcting any defects or errors may be substantial and could adversely affect our operating results.

~~Provision of the Zio service is dependent upon third-party vendors who are subject to disruptions, which could directly or indirectly harm our business and operating results.~~

The analysis we perform to create the diagnostic report for the Zio service is dependent upon a recording made by each device, which requires the physical return of the Zio XT monitor to one of our clinical centers. We predominantly rely on the U.S. Postal Service (“USPS”) to perform this delivery service. Delivery of the Zio XT monitor to one of our clinical centers may be subject to disruption by natural disasters such as earthquake or flooding, labor disagreements or errors on behalf of USPS staff, operational and funding reductions negatively impacting USPS service capabilities, structural issues timely processing in some geographies, or other disruption to the USPS delivery infrastructure. Further, for the Zio AT monitor, we rely on the provision of cellular communication services for the timely transmission of patient information and reportable events. Once received, all data from both Zio XT and AT monitors is processed, curated and reported on through cloud-computing resources. The reliability of these communication and cloud services is also subject to natural disasters, labor disruptions, human error, and infrastructure failure.

Any of these disruptions may render it difficult or temporarily impossible for us to provide some or all of the Zio service, adversely affecting our operating results, causing significant distraction for management, and negatively impacting our business reputation.

Security breaches, loss of data, and other disruptions could compromise sensitive information related to our business or patients, or prevent us from accessing critical information and expose us to liability, which could adversely affect our business and our reputation.

In the ordinary course of our business, we and our third-party billing and collections provider, XIFIN, collect, process, and store sensitive data, including legally protected personally identifiable health information about patients in the United States and in the United Kingdom. This personally identifiable information may include, among other information, names, addresses, phone numbers, email addresses, insurance account information, age, gender, and heart rhythm data. We also process and store, and use additional third parties to process and store, sensitive intellectual property and other proprietary business information, including that of our customers, payors, and collaborative partners. We manage and maintain our applications and data utilizing a combination of on-site systems, managed data center systems, and cloud-based computing center systems. These applications and data encompass a wide variety of business-critical information, including research and development information, commercial information, and business and financial information.

We are highly dependent on information technology networks and systems, including the internet and services hosted by Amazon Web Services and other third-party service providers, to securely process, transmit and store this critical information. Security breaches of this infrastructure, including physical or electronic break-ins, computer viruses, attacks by hackers and similar breaches, can create system disruptions, shutdowns, or unauthorized disclosure or modifications of confidential information involving patient health information to become publicly available. The secure processing, storage, maintenance, and transmission of this critical information are vital to our operations and business strategy, and we devote significant resources to protecting such information, including executing Business Associates Agreements (in compliance with HIPAA) and Data Processing Agreements (in compliance with GDPR) with applicable vendors. Although we take measures to protect sensitive information from unauthorized access or disclosure, cyber-attacks are becoming more sophisticated and frequent, and our information technology and infrastructure, and that of XIFIN and other third parties we utilize to process or store data, may be vulnerable to viruses and worms, phishing attacks, denial-of-service attacks, physical or electronic break-ins, attacks by hackers, breaches due to employee error, malfeasance, or misuse, or similar disruptions from unauthorized tampering. We have in the past been subject to cyber-attacks and data breaches and expect that we will be subject to additional cyber-attacks in the future and may experience future data breaches. While we have implemented data privacy and security measures that we believe are compliant with applicable privacy laws and regulations, some confidential and protected health information, is transmitted to us by third parties, who may not implement adequate security and privacy measures. Further, if third party service providers that process or store data on our behalf experience security breaches or violate applicable laws, agreements, or our policies, such events may also put our information at risk and could in turn have an adverse effect on our business.

A security breach or privacy violation that leads to disclosure or modification of, or prevents access to, patient information, including protected health information, could harm our reputation, compel us to comply with disparate state and federal breach notification laws, require us to verify the correctness of database contents and otherwise subject us to liability under laws that protect personal data, resulting in increased costs or loss of revenue. If we are unable to prevent such security breaches or privacy violations or implement satisfactory remedial measures in a timely manner, the market perception of the effectiveness of our security measures could be harmed, our operations could be disrupted, our brand could be adversely affected, demand for our products and services may decrease, we may be unable to provide the Zio service, we may lose sales and customers, and we may suffer loss of reputation, financial loss and other regulatory penalties because of lost or misappropriated information, including sensitive patient data. We may be required to expend significant capital and financial resources to invest in security measures, protect against such threats or to alleviate problems caused by breaches in security. In addition, these breaches and other inappropriate or unauthorized access can be difficult to detect, and any delay in identifying them may lead to increased harm to individuals. Although we have invested in our systems and the protection of our data to reduce the risk of an intrusion or interruption, and we monitor our systems on an ongoing basis for any current or potential threats, we can give no assurances that these measures and efforts will prevent all intrusions, interruptions, or breakdowns.

Because techniques used to obtain unauthorized access or to sabotage systems change frequently and generally are not recognized until launched, we may be unable to anticipate these techniques or to implement adequate preventive measures.

In the event that patients or physicians enable third parties to access their data on our systems, we cannot ensure the complete integrity or security of such data in our systems as we would not control that access. Third parties may also attempt to fraudulently induce our employees, or patients or physicians who use our technology, into disclosing sensitive information such as user names, passwords or other information. Third parties may also otherwise compromise our security measures in order to gain unauthorized access to the information we store. This could result in significant legal and financial exposure, a loss in confidence in the security of our service, interruptions or malfunctions in our service, and, ultimately, harm to our future business prospects and revenue.

Any such breach or interruption of our systems, or those of XIFIN or any of our third-party information technology partners, could compromise our networks or data security processes and sensitive information could be inaccessible or could be accessed by unauthorized parties, publicly disclosed, lost or stolen. Any such interruption in access, improper access, disclosure or other loss of information could result in legal claims or proceedings, liability under laws that protect the privacy of patient information, such as HIPAA, GDPR, and the U.K. Data Protection Act 2018. Regardless of the merits of any such claim or proceeding, defending it could be costly and divert management’s attention from leading our business. Unauthorized access, loss or dissemination could also disrupt our operations, including our ability to perform our services, bill payors or patients, process claims and appeals, provide customer assistance services, conduct research and development activities, collect, process and prepare company financial information, provide information about our current and future solutions and engage in other patient and clinician education and outreach efforts. Any such breach could also result in the compromise of our trade secrets and other proprietary information, which could adversely affect our business and competitive position.

Depending on the nature of the information compromised, in the event of a data breach or other unauthorized access to or acquisition of our customer, employee and patient data, we may also have obligations to notify users about the incident and we may need to provide some form of remedy for the individuals affected by the incident. A growing number of legislative and regulatory bodies have adopted consumer notification requirements in the event of unauthorized access to or acquisition of certain types of personal data. Such breach notification laws continue to evolve and may be inconsistent from one jurisdiction to another. Complying with these obligations could cause us to incur substantial costs and could increase negative publicity surrounding any incident that compromises personal data within our control (such as that of customers, patients and employees). In addition, the interpretation and application of consumer, health-related and data protection laws, rules and regulations in the United States, the UK, European Union and elsewhere are often uncertain, contradictory and in flux. It is possible that these laws, rules and regulations may be interpreted and applied in a manner that is inconsistent with our practices or those of our distributors and partners. If we or these third parties are found to have violated such laws, rules or regulations, it could result in government-imposed fines, orders requiring that we or these third parties change our or their practices, or criminal charges, which could adversely affect our business. Complying with these various laws could cause us to incur substantial costs or require us to change our business practices, systems and compliance procedures in a manner adverse to our business. In addition, California has enacted the California Consumer Privacy Act (“CCPA”), which became effective on January 1, 2020, and requires, among other things, disclosures to California consumers and afford such consumers abilities to opt out of certain sales of their personal information by us. It remains unclear how various provisions of the CCPA will be interpreted and enforced. The effects of the CCPA and other similar state laws are potentially significant and may require us to modify our data processing practices and policies and to incur substantial costs and expenses in an effort to comply with this legislation.

~~The use, misuse, or off-label use of the Zio service may result in injuries that lead to product liability suits, which could be costly to our business.~~

The use, misuse, or off-label use of the Zio service may in the future result in outcomes and complications potentially leading to product liability claims. For example, we are aware that physicians have prescribed the Zio service off-label for pediatric patients. We have also received and may in the future receive product liability or other claims with respect to the Zio service, including claims related to skin irritation and alleged burns. In addition, if the Zio monitor is defectively designed, manufactured or labeled, contains defective components or is misused, we may become subject to costly litigation initiated by physicians, or the hospitals and clinics where physicians prescribing our Zio service work, or their patients. Product liability claims are especially prevalent in the medical device industry and could harm our reputation, divert management’s attention from our core business, be expensive to defend and may result in sizable damage awards against us.

Although we maintain product liability insurance, we may not have sufficient insurance coverage for future product liability claims. We may not be able to obtain insurance in amounts or scope sufficient to provide us with adequate coverage against all potential liabilities. 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, harm our reputation, significantly increase our expenses, and reduce product sales. Product liability claims in excess of our insurance coverage would be paid out of cash reserves, harming our financial condition and operating results.

~~Our forecasts of market growth may prove to be inaccurate, and even if the markets in which we compete achieve the forecasted growth, our business may not increase at similar rates, if at all.~~

Growth forecasts are subject to significant uncertainty and are based on assumptions and estimates that may not prove to be accurate. Our forecasts relating to, among other things, the expected growth in the ambulatory cardiac monitoring solutions market may prove to be inaccurate.

Our growth is subject to many factors, including whether the market for first-line ambulatory cardiac monitoring solutions continues to improve, the rate of market acceptance of the Zio service as compared to the products of our competitors, and our success in implementing our business strategies, each of which is subject to many risks and uncertainties. If our Zio service works as anticipated to provide a correct first-line diagnosis, it may lead to a decrease in the amount of ambulatory cardiac monitoring orders each year in the United States. This outcome would result if our Zio service is proven to produce the right diagnosis the first time, thereby reducing the need for additional testing. Accordingly, our forecasts of market opportunity should not be taken as indicative of our future growth.

We may acquire other companies or technologies, or enter into joint ventures or other strategic alliances, which could divert our management’s attention, result in additional dilution to our stockholders and otherwise disrupt our operations and harm our operating results.

We may in the future seek to acquire or invest in businesses, applications or technologies that we believe could complement or expand our ambulatory cardiac monitoring solutions portfolio, enhance our technical capabilities or otherwise offer growth opportunities. The pursuit of potential acquisitions may divert the attention of management and cause us to incur various costs and expenses in identifying, investigating and pursuing suitable acquisitions, whether or not they are consummated. We may not be able to identify desirable acquisition targets or be successful in entering into an agreement with any particular target or obtain the expected benefits of any acquisition or investment. In addition, any of these transactions could be material to our financial condition and operating results and expose us to many risks, including:

•~~disruption in our relationships with existing strategic partners or suppliers as a result of such a transaction;~~

•~~unanticipated liabilities related to acquired companies;~~

•~~difficulties integrating acquired personnel, technologies and operations into our existing business;~~

•~~retention of key employees;~~

•~~diversion of management time and focus from operating our business to management of strategic alliances or joint ventures or acquisition integration challenges;~~

•~~increases in our expenses and reductions in our cash available for operations and other uses;~~

•~~possible write-offs or impairment charges relating to acquired businesses; and~~

•~~possible compliance, regulatory, or product issues.~~

To date, the growth of our operations has been largely organic, and we have limited experience in acquiring other businesses or technologies or entering into joint ventures or strategic alliances. Acquisitions, joint ventures or strategic alliances could also result in dilutive issuances of equity securities, the use of our available cash, or the incurrence of debt, which could harm our operating results. In addition, if an acquired business, joint venture or strategic alliance fails to materialize or fails to meet our expectations, our operating results, business and financial condition may suffer.

~~Consolidation of commercial payors could result in payors eliminating coverage or reducing reimbursement rates for our Zio service.~~

When payors combine their operations, the combined company may elect to reimburse our Zio service at the lowest rate paid by any of the participants in the consolidation or use its increased size to negotiate reduced rates. If one of the payors participating in the consolidation does not reimburse for the Zio service at all, the combined company may elect not to reimburse for the Zio service, which would adversely impact our operating results. While attempts by Aetna Inc. to acquire Humana Inc. and Anthem Inc. to acquire Cigna Corp. have been largely abandoned due to antitrust challenges by the DOJ, it is possible that these or other payor consolidations may occur in the future.

~~Our ability to utilize our net operating loss carryovers may be limited.~~

As of December 31, 2021, we had federal and state net operating loss carryforwards (“NOLs”) of $464.3 million and $279.1 million, respectively, which if not utilized will begin to expire in 2027 for federal purposes and have begun expiring for state purposes. We may use these NOLs to offset against taxable income for U.S. federal and state income tax purposes. However, Section 382 of the Internal Revenue Code, as amended, may limit the NOLs we may use in any year for U.S. federal income tax purposes in the event of certain changes in ownership of our company. A Section 382 “ownership change” generally occurs if one or more stockholders or groups of stockholders who own at least 5% of a company’s stock increase their ownership by more than 50 percentage points (by value) over their lowest ownership percentage within a rolling three year period. Similar rules may apply under state tax laws. Future issuances or sales of our stock, including certain transactions involving our stock that are outside of our control, could cause an “ownership change.” If an “ownership change” has occurred in the past or occurs in the future, Section 382 would impose an annual limit on the amount of pre-ownership change NOLs and other tax attributes we can use to reduce our taxable income, potentially increasing and accelerating our liability for income taxes, and also potentially causing those tax attributes to expire unused. Any limitation on using NOLs could, depending on the extent of such limitation and the NOLs previously used, result in our retaining less cash after payment of U.S. federal and state income taxes during any year in which we have taxable income, rather than losses, than we would be entitled to retain if such NOLs were available as an offset against such income for U.S. federal and state income tax reporting purposes, which could adversely impact our operating results.

~~We have identified a material weakness in our internal control over financial reporting which could, if not remediated, result in material misstatements in our financial statements.~~

We are responsible for establishing and maintaining adequate internal control over our financial reporting, as defined in Rule 13a-15(f) under the Securities Exchange Act. As disclosed in Item 9A of our Annual Report on Form 10-K for the year ended December 31, 2021, filed with the SEC on February 28, 2022, we identified a material weakness in our internal control over financial reporting. A material weakness is defined as a deficiency, or combination of deficiencies, in internal control over financial reporting, such that there is a reasonable possibility that a material misstatement of our annual or interim financial statements will not be prevented or detected on a timely basis. As a result of this material weakness, we concluded that our internal control over financial reporting was not effective based on criteria set forth by the Committee of Sponsoring Organization of the Treadway Commission in Internal Control-An Integrated Framework (2013).

To implement remedial measures as disclosed in Item 9A of our Annual Report on Form 10-K for the year ended December 31, 2021, filed with the SEC on February 28, 2022, we committed additional resources, hired additional staff, and provided additional management oversight. If our remedial measures are insufficient to address the material weaknesses, or if additional material weaknesses or significant deficiencies in our internal control over financial reporting are discovered or occur in the future, our consolidated financial statements may contain material misstatements, and we could be required to restate our financial results. In addition, if we are unable to successfully remediate the material weakness that continues to exist and if we are unable to produce accurate and timely financial statements, our stock price may be adversely affected.

Risks Related to ~~Our Intellectual Property~~

We may become a party to intellectual property litigation, litigation resulting from employment disputes, or administrative proceedings that could be costly and could interfere with our ability to provide the Zio service.Healthcare Regulatory Matters

~~The medical device industry has been characterized by extensive litigation regarding patents, trademarks, trade secrets,~~Our use of third-party service providers or iRhythm company resources located outside the United States to support certain customer care, clinical and other ~~intellectual property rights,~~operations of our IDTFs may present challenges, and ~~companies~~if we are ineffective in ~~the industry have used intellectual property litigation to gain a competitive advantage. It is possible that U.S. and foreign patents and pending patent applications~~limiting work performed by these service providers or ~~trademarks controlled by third parties, especially those held by~~iRhythm consistent with applicable regulations or our ~~competitors, may be alleged to cover our products or services, or that~~contractual agreements with commercial payors, we may be ~~accused~~subject to penalties or experience loss of ~~misappropriating~~revenue.

Beginning in the third ~~parties’ trade secrets. Additionally, our products include hardware~~quarter of 2022, we engaged Sutherland Healthcare Solutions, Inc. and ~~software components that we purchase from vendors,~~Techindia Infoway Private Limited, to support certain customer care and ~~may include design components that are outside~~clinical operations of our ~~direct control. Our competitors, many of which~~IDTFs. We have ~~substantially greater resources~~developed operational and ~~have made substantial investments in patent portfolios, trade secrets, trademarks, and competing technologies, may have applied for or obtained, or may in~~technical controls to limit the ~~future apply for or obtain, patents or trademarks that will prevent, limit or otherwise interfere~~work performed by these vendors consistent with our ~~ability~~interpretation of the Medicare coverage exclusion for items of services furnished outside the United States, other applicable laws and regulations, and any requirements imposed pursuant to ~~make, use, sell and/~~our contracts with commercial payors. If these controls do not work as intended, or ~~export~~if regulators or commercial payors disagree with our ~~products~~interpretation of these requirements and ~~services or~~their application to use product names. Moreover, in recent years, individuals and groups that are non-practicing entities, commonly referred to as “patent trolls,” have purchased patents or otherwise obtained rights to other intellectual property assets for the purpose of making claims of infringement in order to extract settlements. From time to time,our operations, we may ~~receive threatening letters, notices or “invitations~~be subject to ~~license,” or may be the subject of claims that~~a requirement to return funds already paid to us, civil monetary penalties, other government enforcement, as highlighted by a recent enforcement action against our products and business operations infringe or violate the intellectual property rights of others. The defense of these matters can be time-consuming, costly to defend in litigation, divert management’s attention and resources, damage our reputation and brand, and cause us to incur significant expenses or make substantial payments to satisfy judgments or settle claims. Vendors from which we purchase hardware or software may not indemnify or defend us in the event that such hardware or software is accused of infringing a third-party’s patent or trademark or of misappropriating a third-party’s trade secrets.

Further, if such patents, trademarks, or trade secrets are successfully asserted against us, this may harm our business and result in injunctions preventing us from selling our products, license fees, damages and the payment of attorney’s fees and court costs. In addition, if we are found to have willfully infringed third-party patents or trademarks or to have misappropriated trade secrets, we could be required to pay treble damages in addition to other penalties. Although patent, trademark, trade secret, and other intellectual property disputes in the medical device and services area have often been settled through licensing or similar arrangements, costs associated with such arrangements may be substantial and could include ongoing royalties. We may be unable to obtain necessary licenses on satisfactory terms, if at all. If we do not obtain necessary licenses, we may not be able to redesign our Zio monitors or our Zio service to avoid infringement and our product development efforts may be negatively affected as a result.

~~Similarly, interference or derivation proceedings provoked by third parties or brought by the U.S. Patent and Trademark Office (“USPTO”) may be necessary to determine priority~~competitor, BioTelemetry, Inc., with respect to ~~our patents, patent applications, trademarks or trademark applications. We may also become involved in other proceedings, such~~the support of certain clinical operations by vendors performing work outside the United States, and termination of contracts with commercial payors, as ~~reexamination, inter partes review, derivation or opposition proceedings before~~well as the ~~USPTO or other jurisdictional body relating to our intellectual property rights or the intellectual property rights~~loss of others. Adverse determinations in a judicial or administrative proceeding or failure to obtain necessary licenses could prevent us from manufacturing the Zio monitors and selling the Zio service or using product names, which would have a significant adverse impact on our business.

Additionally, we may need to commence proceedings against others to enforce our patents or trademarks, to protect our trade secrets or know how, or to determine the enforceability, scope and validity of the proprietary rights of others. These proceedings would result in substantial expense to us and significant diversion of effort by our technical and management personnel. We may not prevail in any lawsuits that we initiate, a scenario that could also result in the invalidation of our asserted patents, and the damages or other remedies awarded, if any, may not be commercially meaningful. We may not be able to stop a competitor from marketing and selling products that are the same or similar to our products and services or from using product or service names that are the same or similar to ours, and our business may be harmed as a result.

We use certain open source software in the infrastructure supporting the Zio service. Licensees of open source software may be required to make public and use certain source code, to license proprietary software for free or to make certain derivative works available to others. As a result, we may face claims from companies that incorporate open source software into their products or from open source licensors, claiming ownership of, or demanding release of, the source code, the open source software or derivative works that were developed using such software, or otherwise seeking to enforce the terms of the applicable open source license. These claims could result in litigation and could require us to cease offering the Zio service unless and until we can re-engineer it to avoid infringement. This re-engineering process could require significant additional research and development resources, and we may not be able to complete it successfully. While we monitor and control the use of open source software in the Zio service and in any third party software that is incorporated into the Zio service, and we try to ensure

that no open source software is used in such a way as to require us to disclose the source code underlying the Zio service, there can be no guarantee that such use could not inadvertently occur. These risks could be difficult to eliminate or manage, and, if not addressed, could harm our business, intellectual property protection, financial condition and operating results.

~~Intellectual property rights may not provide adequate protection, which may permit third parties to compete against us more effectively.~~revenue associated with those contracts.

In ~~order to remain competitive,~~addition, we must develop and maintain protection of the proprietary aspects of our technologies. We rely on a combination of patents, copyrights, trademarks, trade secret laws and confidentiality and invention assignment agreementsare currently engaging with employees and third parties to protect our intellectual property rights. As of December 31, 2021, we owned, or retained exclusive license to, twenty-three issued U.S. patents, the earliest of which will expire in 2028. As of December 31, 2021, we also owned, or retained an exclusive license to, eight issued patents from the Japanese Patent Office, two issued patents from the Australian Patent Office, four issued patents from the Canadian Patent Office, five issued patents from the European Patent Office, three issued patents from the Korean Patent Office, and one issued patent from the Chinese Patent Office. The earliest expiration date of these international patents is 2027. As of December 31, 2021, we had twenty-six pending patent applications globally, including twelve inother third-party service providers that have resources located outside the United States, ~~three~~and we are establishing iRhythm company resources in the ~~European Patent Office, four~~Philippines to provide services in ~~Japan, three Patent Cooperation Treaty (“PCT”) international applications,~~support our IDTFs. We intend for these services to include benefits verification, billing, collections, and ~~one in each~~customer service, which will require complex oversight and monitoring for appropriate capture and escalation of ~~Australia, Korea, China and India. Our patents and patent applications are directed to covering key aspects of the design, manufacture and use of the Zio monitor and the Zio service.~~

We rely, in part, on our ability to obtain and maintain patent protection for our proprietary products and processes. The process of applying for and obtaining a patent is expensive, time-consuming and complex, and we may not be able to file, prosecute, maintain, enforce or license all necessary or desirable patent applications at a reasonable cost, in a timely manner, or in all jurisdictions where protectioncomplaint information that may be ~~commercially advantageous, or we may not be able~~relevant to ~~protect~~the quality, performance, and safety of our proprietary rights at all. Despite our efforts to protect our proprietary rights, unauthorized parties may be able to obtain and use information that we regard as proprietary. In addition, the issuance of a patent does not ensure that it is valid or enforceable, so even if we obtain patents, they may not be valid or enforceable against third parties. Our patent applications may not result in issued patents and our patents may not be sufficiently broad to protect our technology. Issued international patents may carry a requirement to “work” a patent in the applicable geography; failure to do so could lead to loss of the patentmedical devices or the ~~requirement to accept licensing terms, both~~quality of ~~which would be favorable to~~ our competitors. Furthermore, the issuance of a patent does not give us the right to practice the patented invention. Third parties may have blocking patents that could prevent us from marketing our own products and practicing our own technology. Alternatively, third parties may seek approval to market their own products similar to or otherwise competitive with our products. In these circumstances, we may need to defend and/or assert our patents, including by filing lawsuits alleging patent infringement. In any of these types of proceedings, a court or agency with jurisdiction may find our patents invalid or unenforceable; competitors may then be able to market products and use manufacturing and analytical processes that are substantially similar to ours. Even if we have valid and enforceable patents, these patents still may not provide protection against competing products or processes sufficient to achieve our business objectives. Litigation is time-consuming and expensive and would divert our resources.

clinical services. If we are unable to ~~protect the confidentiality of our trade secrets~~effectively manage this oversight and ~~other proprietary information, our business and competitive position may be harmed.~~

~~We rely heavily on trade secrets as well as invention assignment and confidentiality provisions that~~monitoring, we have in contracts with our employees, consultants, collaborators and others to protect our algorithms and other aspects of our Zio service. We may not be able to prevent the unauthorized disclosure or use of our technical knowledge or other trade secrets by consultants, vendors or former or current employees, despite the existence generally of these confidentiality agreements and other contractual restrictions. These agreements may not provide meaningful protection for our trade secrets, know-how, or other proprietary information in the event of any unauthorized use, misappropriation, or disclosure of such trade secrets, know-how, or other proprietary information. There can be no assurance that employees, consultants, vendors and clients have executed such agreements or have not breached or will not breach their agreements with us, that we will have adequate remedies for any breach, or that our trade secrets will not otherwise become known or independently developed by competitors. Despite the protections we do place on our intellectual property, monitoring unauthorized use and disclosure of our intellectual property is difficult, and we do not know whether the steps we have taken to protect our intellectual property will be adequate. In addition, the laws of many foreign countries will not protect our intellectual property rights to the same extent as the laws of the United States. Consequently, we may be unable to prevent our proprietary technology from being exploited abroad, which could affect our ability to expand to international markets or require costly efforts to protect our technology.

~~We may also employ individuals who were previously or are concurrently employed at research institutions or other medical device companies, including our competitors or potential competitors. We~~ may be subject to ~~claims that these employees,~~regulatory enforcement action or ~~we, have inadvertently or otherwise used or disclosed trade secrets or other proprietary information of their former or concurrent employers, or that patents~~inquiries which may be expensive and ~~applications we have filed~~time consuming to ~~protect inventions of these employees, even those~~resolve. In addition, certain contracts with commercial payors include restrictions related to one or more of our products, are rightfully owned by their former or concurrent employer. Litigation may be necessary to defend against these claims. Even if we are successful in defending against these claims, litigation could result in substantial costs and be a distraction to management.

To the extent our intellectual property protection is incomplete, we are exposed to a greater risk of direct competition. A third party could, without authorization, copy or otherwise obtain and use our products or technology, or develop similar technology. Our competitors could purchase our products and attempt to replicate some or all of the competitive advantages we derive from our development efforts or design around our protected technology. Our failure to secure, protect and enforce our intellectual property rights could substantially harm the value of our Zio service, brand and business. The theft or unauthorized use or publication of our trade secrets and other confidential business information could reduce the differentiation of our products and harm our business, the value of our investment in development or business acquisitions could be reduced and third parties might make claims against us related to losses of their confidential or proprietary information. Any of the foregoing could materially and adversely affect our business.

Further, it is possible that others will independently develop the same or similar technology or otherwise obtain access to our unpatented technology, and in such cases we could not assert any trade secret rights against such parties. Costly and time-consuming litigation could be necessary to enforce and determine the scope of our trade secret rights and related confidentiality and nondisclosure provisions. If we fail to obtain or maintain trade secret protection, or if our competitors obtain our trade secrets or independently develop technology similar to ours or competing technologies, our competitive market position could be materially and adversely affected. In addition, some courts inside andaccessing patient data outside the United States ~~are less willing or unwilling~~and we have implemented technical controls intended to ~~protect trade secrets,~~prohibit access to patient data by service providers and ~~agreement terms that address non-competition are difficult to enforce in many jurisdictions, and might not be enforceable in certain cases.~~

~~If our trademarks and tradenames are not adequately protected, then we may not be able to build name recognition in our markets and our business may be adversely affected.~~

We rely on trademarks, service marks, trade names and brand names, such as our registered trademark “ZIO,” to distinguish our products from the products of our competitors, and have registered or applied to register these trademarks. We cannot assure you that our trademark applications will be approved. During trademark registration proceedings, we may receive rejections. Although we are given an opportunity to respond to those rejections, we may be unable to overcome such rejections. In addition, in proceedings before the USPTO and in proceedings before comparable agencies in many foreign jurisdictions, third parties are given an opportunity to oppose pending trademark applications and to seek to cancel registered trademarks. Opposition or cancellation proceedings may be filed against our trademarks, and our trademarks may not survive such proceedings. In the event that our trademarks are successfully challenged, we could be forced to rebrand our products, which could result in loss of brand recognition and could require us to devoteiRhythm company resources towards advertising and marketing new brands. Further, we cannot assure you that competitors will not infringe our trademarks or that we will have adequate resources to enforce our trademarks. Additionally, we are aware of at least one third party that has registered the “IRHYTHM” mark in the European Union in connection with computer software for controlling and managing patient medical information, heart rate monitors, and heart rate monitors to be worn during moderate exercise, among other uses. We and the third party are involved in adversary proceedings before the Trademark Office in the European Union, and those proceedings could impact our ability to obtain a European Union trade mark registration for the “IRHYTHM” mark, although we already own many national registrations for IRHYTHM in Europe.

~~Changes in patent law could diminish the value of patents in general, thereby impairing our ability to protect our existing and future products.~~

Recent patent reform legislation could increase the uncertainties and costs surrounding the prosecution of patent applications and the enforcement or defense of issued patents. In 2011, the Leahy-Smith America Invents Act (“Leahy-Smith Act”) was signed into law. The Leahy-Smith Act includes a number of significant changes to U.S. patent law. These include provisions that affect the way patent applications are prosecuted and also may affect patent litigation. These also include provisions that switchedlocated outside the United States for these commercial payors, as appropriate. If these controls do not work as intended, or if the payor information we receive from ~~a “first-to-invent” system to a “first-to-file” system, allow third-party submission~~ordering healthcare providers is delayed or inaccurate, we may encounter the suspension or termination of prior art to the USPTO during patent prosecution and set forth additional procedures to attack the validity of a patent by the USPTO, administered post grant proceedings. Under a first-to-file system, assuming the other requirements for patentability are met, the first inventor to file a patent application generally will be entitled to the patent on an invention regardless of whether another inventor had made the invention earlier. Under the new post grant provisions of the Leahy-Smith Act, the USPTO introduced procedures that provide additional administrative pathways for third parties to challenge issued patents. Inter partes review (“IPR”) is one of these procedures. The number of IPR challenges filed is increasing, and in many cases, the USPTO is canceling or significantly narrowing issued patent claims. Accordingly, even if a patent is granted by the USPTO, there is risk that it may not withstand an IPR challenge. Accordingly, it is not clear what, if any, impact the Leahy-Smith Act will have on the operation of our business. The Leahy-Smith Act and its implementation could increase the uncertainties and costs surrounding the prosecution of our patent applications and the enforcement or defense of our issued patents, all of which could have a material adverse effect on our business, financial condition, results of operations and prospects.

In addition, patent reform legislation may pass in the future that could lead to additional uncertainties and increased costs surrounding the prosecution, enforcement and defense of our patents and applications. Furthermore, the U.S. Supreme Court and the U.S. Court of Appeals for the Federal Circuit have made, and will likely continue to make, changes in how the patent laws of the United States are interpreted. Recent case law has increased uncertainty regarding the availability of patent protection for certain technologies and the costs associatedcontracts with obtaining patent protection for those technologies. For example, the U.S. Supreme Court has ruled on several patent cases in recent years, either narrowing the scope of patent protection available in certain circumstances or weakening the rights of patent owners in certain situations. In particular, the 2014 decision by the U.S. Supreme Court in ~~Alice Corp. v. CLS Bank International~~ has increased the difficulty of obtaining new software patents and enforcing existing software patents. Similarly, foreign courts have made, and will likely continue to make, changes in how the patent laws in their respective jurisdictions are interpreted. We cannot predict future changes in the interpretation of patent laws or changes to patent laws that might be enacted into law by U.S. and foreign legislative bodies. Those changes may materially affect our patents or patent applications and our ability to obtain additional patent protection in the future.

~~Risks Related to Government Regulation~~

~~Changes in the regulatory environment may constrain or require us to restructure our operations, which may harm our revenue and operating results.~~

Healthcare laws and regulations, and interpretations of the same, change frequently and may change significantly in the future. We may not be able to adapt our operations to address every new regulation, and new regulations may adversely affect our business. We cannot assure you that a review of our business by courts or regulatory authorities would not result in a determination that adversely affects our revenue and operating results, or that the healthcare regulatory environment will not change in a way that restricts our operations. In addition, there is risk that the U.S. Congress may implement changes in laws and regulations governing healthcare service providers, including measures to control costs, or reductions in reimbursement levels, which may adversely affect our business and results of operations.

~~Government~~commercial payors, ~~such as CMS,~~ as well as ~~insurers,~~any contractual remedies such payors might pursue. The suspension or loss of any of our key commercial payor agreements would have increased their efforts to control the cost, utilization, and delivery of healthcare services. From time to time, the U.S. Congress has considered and implemented changes in the CMS fee schedules in conjunction with budgetary legislation. Further reductions of reimbursement by CMS for services, or changes in policy regarding coverage of tests or other requirements for payment, such as prior authorization or a physician or qualified practitioner’s signature on orders, may be implemented from time to time. Reductions in the reimbursement rates and changes in payment policies of other third-party payors may occur as well. Similar changes in the past have resulted in reduced payments as well as added costs and have added more complex regulatory and administrative requirements. For example, on January 29, 2021, Novitas Solutions, a MAC that we, physicians, and hospitals rely on to process Medicare reimbursement claims related to our Zio service, published reimbursement rates that were considerably lower than expected. On January 10, 2022, Novitas Solutions published rates for 2022 that were retroactive to January 1, 2022 and replaced the rates that it had published in 2021. These revised rates were higher than the rates posted in 2021, but continue to be significantly below the historical Medicare rates for our Zio XT service. Further changes in federal, state, local, and third-party payor regulations or policies may have a materialan adverse impact on our ~~business. Actions by agencies regulating insurance or changes in other laws, regulations, or policies may also have a material adverse effect on~~revenue and our ~~business.~~results of operations.

If we fail to comply with medical device, healthcare and other governmental regulations, we could face substantial penalties and our business, results of operations, and financial condition could be adversely affected.

The ~~products~~services and ~~services~~related devices we offer are highly regulated, and ~~there can be no assurance that~~ the regulatory environment in which we operate ~~will not~~may change significantly and adversely in the future. Our arrangements with physicians, hospitals, clinics, and other stakeholders in the healthcare industry may expose us to broadly applicable medical device laws and healthcare fraud and abuse and other laws and regulations that may restrict the financial arrangements and relationships through which we market, sell, distribute, and ~~distribute~~provide our ~~products~~services and ~~services.~~related devices. Our employees, consultants, and commercial partners and collaborators may engage in misconduct or other improper activities, including non-compliance with regulatory standards and requirements. Federal and state healthcare laws and regulations that may affect our ability to conduct business, include, without limitation:

•federal and state laws and regulations regarding billing and claims ~~payment applicable to our Zio service and regulatory agencies enforcing those laws and regulations;~~payment;

•the federal Anti-Kickback Statute, which prohibits, among other things, any person from knowingly and willfully offering, soliciting, receiving, or providing remuneration, directly or indirectly, in exchange for or to induce either the referral of an individual for, or the purchase, order or recommendation of, any good or service for which payment may be made under federal healthcare programs, such as the ~~CMS~~Medicare and Medicaid programs;

•the federal False Claims Act, which prohibits, among other things, individuals or entities from knowingly presenting, or causing to be presented, false claims, or knowingly using false statements, to obtain payment from the federal government;

•federal criminal laws that prohibit executing a scheme to defraud any healthcare benefit program or making false statements relating to healthcare matters;

•the FCPA, the ~~U.K.~~UK Bribery Act of 2010, and other local anti-corruption laws that apply to our international activities;

•the federal Physician Payment Sunshine Act, or Open Payments, ~~created under the Affordable Care Act,~~ and its implementing regulations, which requires ~~manufacturers of drugs, medical devices, biologicals and medical supplies for which payment is available under Medicare, Medicaid, or the Children’s Health Insurance Program~~us to report ~~annually to the U.S. Department of Health and Human Services, information related to~~ payments or other transfers of value made to licensed physicians and certain mid-level health

practitioners and teaching hospitals, as well as ownership and investment interests held by physicians and their immediate family members;

•HIPAA, as amended by the Health Information Technology for Economic and Clinical Health Act, and its implementing regulations, which impose certain requirements relating to the privacy, security, and transmission of individually identifiable health information; HIPAA also created criminal liability for knowingly and willfully falsifying or concealing a material fact or making a materially false statement in connection with the delivery of or payment for healthcare benefits, items or services;

•~~The E.U.~~the GDPR and the ~~U.K.~~UK Data Protection Act 2018, which each provide legal requirements for the handling and disclosure (including across borders) of personal data collected in the European Union and the United Kingdom, respectively;

•the FDA’s Code of Federal Regulations, including but not limited to, 21 CFR Parts 820, 803, 806, and 801, that outlines requirements for medical device design, testing, marketing authorization, manufacturing, labeling, distribution, and post-market surveillance requirements;

•the ~~European Union’s Medical Device Directives~~EU MDD and ~~Medical Device Regulations (“~~EU ~~MDR”)~~MDR that outline requirements for medical device CE marking;

•the ~~United Kingdom’s Medical Device Regulations~~UK MDR, which, post the United Kingdom’s withdrawal from the European Union, replaces the CE marking requirement for medical devices sold in the United Kingdom with a ~~UK Conformity Assessment (UKCA)~~UKCA mark; and

•state law equivalents of each of the above U.S. federal laws, such as anti-kickback and false claims laws which may apply to items or services reimbursed by any third-party payor, including commercial insurers, and state and foreign laws governing the privacy and security of ~~health~~individually identifiable information in certain circumstances (e.g., the Telephone Consumer Protection Act, the CAN-SPAM Act, and state privacy, consumer protection, and breach notification laws), many of which differ from each other in significant ways and often are not preempted by HIPAA, thus complicating compliance efforts.

~~The Affordable Care Act was enacted~~

These laws are broad in ~~2010. The Affordable Care Act, among other things, amends the intent requirement of the federal Anti-Kickback Statute~~scope and criminal healthcare fraud statutes. A person or entity no longer needs to have actual knowledge of this statute or specific intent to violate it. In addition, the Affordable Care Act provides that the government may assert that a claim including items or services resulting from a violation of the federal Anti-Kickback Statute constitutes a false or fraudulent claim for purposes of the False Claims Act.

~~Because of the breadth of these laws~~available exceptions and ~~the narrowness of available statutory and regulatory~~ exemptions are narrow; it is possible that some of our activities could be subject to challenge under one or more of such laws. Any action brought against us for violations of these laws or regulations, even successfully defended, could cause us to incur significant legal expenses and divert our management’s attention from the operation of our business. We may be subject to private “qui tam” actions brought by individual whistleblowers on behalf of the federal or state governments, with potential liability under the federal ~~False Claims Act~~FCA including mandatory treble damages and significant per-claim penalties, which were increased tofrom $12,537 to $25,076 per false claim in May 2022. For example, our industry has experienced recent False Claims Act enforcement, which highlights the importance of compliance with the rules and regulations governing claims submitted to federal healthcare programs.

Although we have adopted policies and procedures designed to comply with these laws and regulations and conduct internal reviews of our compliance with these laws, our compliance is also subject to governmental review. The growth of our business and sales organization and our expansion outside of the United States may increase the potential of violating these laws or our internal policies and procedures. The risk of our being found in violation of these or other laws and regulations is further increased by the fact that many have not been fully interpreted by the regulatory authorities or the courts, and their provisions are open to a variety of interpretations. Any action brought against us for violation of these or other laws or regulations, even if we successfully defend against it, could cause us to incur significant legal expenses and divert our management’s attention from the operation of our business. If our operations are found to be in violation of any of the federal, state, or foreign laws described above or any other current or future fraud and abuse or other healthcare laws and regulations that apply to us, we may be subject to penalties, including significant criminal, civil, and administrative penalties, damages, fines, imprisonment for individuals, exclusion from participation in government programs, such as Medicare, and ~~Medicaid, and~~ we could be required to curtail or cease our operations. Any of the foregoing consequences could seriously harm our business and our financial results.

The Zio monitors, including the associated software and algorithm, and the Zio service are subject to extensive regulation by the FDA and CMS in the United States, and by the Competent Authorities in the European Union and the United Kingdom. Such regulations are wide ranging and govern, among other things:

•~~product design, development, manufacture, and release;~~

•~~laboratory, preclinical and clinical testing, labeling, packaging, storage and distribution;~~

•~~premarketing clearance or approval;~~

•~~service operations, including IDTF locations;~~

Our business relies on orders from licensed healthcare providers, and the continuing clinical acceptance and adoption of our Zio Services depends upon strong working relationships with healthcare providers, including physicians. These relationships, interactions, and arrangements are subject to a high degree of scrutiny by government regulators and enforcement bodies.

As a CMS-enrolled IDTF, we ~~are granted regulatory clearances or approvals, they~~ may ~~include significant limitations~~only provide our Zio Services upon receipt of a valid order from a licensed healthcare provider for use in the diagnosis and treatment of a patient’s medical condition. Accordingly, our revenue and the success of our business rely on the ~~indicated uses for~~continued clinical acceptance and adoption of our Zio Services by healthcare providers whose patients require remote cardiac monitoring services. In addition to continuing to demonstrate the ~~product, which may limit~~clinical value of our Zio Services, we also must support widespread clinical acceptance and adoption of our Zio Services by maintaining strong working relationships with these healthcare providers, including physicians. However, as we work to establish and maintain these relationships, we face significant scrutiny of these relationships, interactions, and arrangements by government regulators and enforcement agencies. Failure to maintain these relationships, interactions, and arrangements in compliance with applicable laws and regulations, including those targeted at fraud and abuse like the ~~market for the product. Although we have obtained 510(k) clearance to market the Zio monitors~~federal Anti-Kickback Statute and the ~~Zio service (Software~~False Claims Act, could expose us to significant legal and financial repercussions, including government civil and criminal investigations, civil monetary penalties, criminal penalties, and/or exclusion from federal healthcare programs.

Our communications with healthcare stakeholders – physicians and other healthcare professionals, payors and similar entities, as well as patients and lay caregivers – are subject to a ~~Medical Device elements~~high degree of scrutiny for compliance with a wide range of laws and regulations. Continuing or increasing our sales and marketing and other external communication efforts may expose us to additional risk of being alleged or deemed to be non-compliant by regulatory, enforcement authorities, or competitors.

There is potential for differing interpretations of whether certain communications are consistent with a product’s FDA-required labeling, and FDA will evaluate communications on a fact-specific basis. The FTC also recently released updated guidance on health claims, with a high expectation for clinical data to devices and their uses can trigger the need for a new 510(k). FDA requirements dictate that we must evaluate potential changes and document our decision-making regarding the need for additional submissions and clearances.support these claims.

In addition, ~~we are required~~making comparative claims may draw scrutiny from our competitors. Where a company makes a claim in advertising or promotion that its product is superior to ~~file various reports~~the product of a competitor (or that the competitor’s product is inferior), this creates a risk of a lawsuit by the competitor under federal and state false advertising or unfair and deceptive trade practices law, and possibly also state libel law. Such a suit may seek injunctive relief against further advertising, a court order directing corrective advertising, and compensatory and punitive damages where permitted by law. If our compliance program and training and monitoring do not effectively keep pace with ~~the FDA,~~our sales and E.U. or U.K. regulators, including reports required by each jurisdiction's adverse event and field action reporting regulations. These reports are often required for if our Zio monitors or service may have caused or contributed to a death or serious injury or malfunctioned in a way that would likely cause or contribute to a death or serious injury if the malfunction were to recur.

These reports are typically publicly available information in most jurisdictions, including the United States.~~and other exposure.

If we initiate a recall (whether a correction made relative to a device that remains in the field, which could be through a labeling or software update, or removal and return of that device to us) for our Zio service to reduce a risk to health posed by the Zio service, we would be required to submit a publicly available Correction and Removal report to the FDA and, in many cases, similar reports to other regulatory agencies. Depending on the reason for the correction and removal and the potential severity of the impact to patient safety or the effectiveness of the device, FDA may require differing degrees of communication to alert those who may be in possession of an impacted device. We would generally be subject to similar requirements in jurisdictions outside the United States where the Zio services is used. Furthermore, even if we adhere to regulatory standards and expectations in our corrective actions, the public nature of recalls can result in broader negative publicity and perceptions, which could harm our reputation.

We ~~have several monitoring centers throughout~~may also seek to communicate certain information with physicians and scientists or with payors and similar entities, and may rely on a range of laws, regulations, regulatory guidance governing topics including scientific exchange and communication of healthcare economic information (“HCEI”) and product information under the United States that analyze the data obtained from cardiac monitors and report related preliminary observation to physicians. In order for us to receive reimbursement from Medicare and some commercial payors, our monitoring centers must be enrolled as IDTFs in the Medicare program. Enrollment as an IDTF requires that we follow strict regulations governing how our monitoring centers operate, such as requirements regarding qualifications of the technicians who review data transmitted from our monitors. These rules can vary from location to location and are subject to change. If they change, we may have to change the operating procedures at our monitoring centers, which could increase our costs significantly. If we fail to obtain and maintain our IDTF enrollment, our services may no longer be reimbursed by Medicare and some commercial payors, which could have a material adverse impact on our business.Preapproval Information Exchange Act.

As a Medicare-enrolled IDTF, we are prohibited from directly soliciting patients for diagnostic medical procedures. While we can engage in general marketing initiatives, consistent with applicable law, we cannot make telephone, computer, and in-person contacts for the purpose of soliciting business for our IDTF.

Regarding patients for whom we have received a valid order for our Zio Services, we may send or make text messages, emails, phone calls and other communications for various informational, business purposes, including to confirm accurate demographic and payor information or to assist a patient via a home hookup. Communication-related laws require consent prior to certain communications and provide a specified monetary damage award or fine for each violation could result in particularly significant damage awards or fines. For example, under the Telephone Consumer Protection Act (“TCPA”), plaintiffs may seek actual monetary loss or statutory damages of $500 per violation, whichever is greater, and courts may treble the damage award for willful or knowing violations. In the wake of a 2021 decision by the U.S. Supreme Court that limited the applicability of the TCPA, several states have enacted or introduced legislation that would regulate text messages and certain telephone calls to individuals. We may be subject to lawsuits (including class-action lawsuits) containing allegations that our business violated the TCPA or other communications laws. These lawsuits may seek damages (including statutory damages) and injunctive relief, among other remedies. A determination that there have been violations of the TCPA or other statutes regulating communications with patients could expose us to significant damage awards that could, individually or in the aggregate, materially harm our business.

While most of our revenue results from claims submitted to payors for diagnostic medical procedures, we offer, and are looking to expand, alternative payment and service delivery models. Piloting, evaluating, and implementing these alternative payment and service delivery models requires interactions with commercial payors, physicians, and patients; these interactions are subject to laws and regulations aimed at preventing healthcare fraud and abuse. If these models are unsuccessful, or if we are unable to fully comply with such laws as we pursue these strategies, our commercial success could be compromised and we could face substantial penalties.

Our operations may be directly or indirectly affected by various broad state and federal healthcare fraud and abuse laws, including the AKS, the FCA, the Anti-Mark Up Rule, and the Medicare Beneficiary Inducement Statute. For some of our services, we directly bill physicians or other healthcare entities, that, in turn, bill payors, and the amounts we bill may include a risk-based pricing component. We are also developing alternative service delivery models that include using our Zio XT System to screen at-risk patient populations as part of a value-added service offered by managed care organizations, including Medicare Advantage Organizations, to qualifying participants. Although we believe these billing and service models and our program development efforts are properly designed to comply with laws and regulations, these types of initiatives may draw a high degree of scrutiny and may subject us to assertions of non-compliance. If our past, present, or future operations are found to be in violation of fraud and abuse laws, we or our officers may be subject to civil or criminal penalties, including large monetary penalties, damages, fines, imprisonment and exclusion from Medicare program participation. Furthermore, if we knowingly file, or “cause” the filing of, false claims for reimbursement with government programs such as Medicare, we may be subject to ~~a range~~substantial civil penalties, including treble damages.

Risks Related to Financial and Accounting Matters

In the future we may identify additional material weaknesses or otherwise fail to maintain an effective system of ~~potential regulatory enforcement actions or required to take corrective actions,~~internal controls, which ~~depending on their nature and scope could harm our business.~~

~~The FDA and FTC also regulate the advertising and promotion~~may result in material misstatements of our ~~products~~consolidated financial statements or cause us to fail to meet our periodic reporting obligations.

We previously identified material weaknesses in our internal control over financial reporting. A material weakness is a deficiency, or a combination of deficiencies, in internal control over financial reporting, such that there is a reasonable possibility that a material misstatement of our annual or interim consolidated financial statements will not be prevented or detected on a timely basis. As previously disclosed, in preparing our consolidated financial statements as of and ~~services, requiring not only~~for the years ended December 31, 2021 and 2020, our management concluded that our ~~claims~~disclosure controls and procedures were not effective at the reasonable assurance level due to a failure to maintain a sufficient number of professionals with an appropriate level of accounting and internal control knowledge, training, and experience to timely and accurately analyze, record, and disclose accounting matters. This material weakness contributed to additional material weaknesses, which have been previously disclosed and remediated. In aggregate, these material weaknesses (including the previously remediated material weaknesses) contributed to the misstatement of our revenues, revenue reserves, bad debt expense, property and equipment, research and development expense, and related financial disclosures, and in the revision of the Company’s consolidated financial statements for the years ended December 31, 2017, December 31, 2018, and each interim period therein as well as the quarters ended March 31, 2019, June 30, 2019, and September 30, 2019. Additionally, this material weakness could result in a misstatement of account balances or disclosures that would result in a material misstatement to the annual or interim consolidated financial statements that would not be ~~truthful~~prevented or detected.

To address this material weakness, we took actions designed to improve our internal control over financial reporting and ~~not misleading, but also~~remediate the control deficiencies that ~~claims about~~led to the material weakness, including hiring additional accounting and finance personnel with an appropriate level of expertise, providing for additional management oversight over financial reporting including through the establishment of a SOX Steering Committee within our ~~devices~~internal audit function, and ~~services are consistent with 510(k) clearances~~implementing new controls and processes. As of the year ended December 31, 2022, we concluded that our remediation efforts have been successful and that ~~data~~the previously identified material weakness in internal control over financial reporting has been remediated.

Our internal control over financial reporting will not prevent or detect all errors and ~~make~~all fraud. A control system, no matter how well designed and operated, can provide only reasonable, not absolute, assurance that the control system’s objectives will be met. Because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that misstatements due to error or fraud will not occur or that all control issues and instances of fraud will be detected.

Any failure to implement and maintain effective internal control over financial reporting could cause investors to lose confidence in our reported financial and other ~~corrections~~information, adversely impact our stock price, cause us to incur increased costs to remediate any deficiencies, and attract regulatory scrutiny or ~~restitutions. Similar~~lawsuits that could be costly to resolve and distract management’s attention, limit our ability to access the capital markets or cause our stock to be delisted from The Nasdaq Global Select Market or any other securities exchange on which it is then listed. Failure to remedy any material weakness in our internal control over financial reporting, or to implement or maintain other effective control systems required of public companies, could also restrict our future access to the ~~FDA~~capital markets.

Our financial results may fluctuate significantly from quarter-to-quarter and ~~FTC,~~may not fully reflect the ~~European Union under~~underlying performance of our business.

Our revenue and operating results may fluctuate significantly from quarter to quarter as a result of a variety of factors, a number of which are outside our control, and may therefore not fully reflect the ~~EU Medical Device Regulations~~underlying performance of our business. Such factors may include, for example, seasonal variations in prescription rates. We typically experience reduced revenue during the third quarter, as well as during the year-end holiday season. We believe this is the result of physicians and patients taking vacations, and patients electing to delay our monitoring services during the ~~United Kingdom under~~summer months and holidays. We believe that period-to-period comparisons of our operating results may not be meaningful and should not be relied on as an indication of our future performance. If quarterly revenues or operating results fall below the ~~UK Medical Device Regulations have similar requirements~~expectations of investors or public market analysts, the trading price of our common stock could decline substantially. Factors that might cause quarterly fluctuations in our operating results include:

~~The FDA, CMS, FTC,~~•possible delays in our research and ~~state~~development programs or in the completion of any third-party clinical trials relating to our Zio Services;

•~~withdrawal or restriction of regulatory clearance or premarket approvals that have already been granted;~~inadequate financial and other resources; and

•~~criminal prosecution.~~

~~If any of these events were to occur, our business~~global political and ~~financial condition could be harmed.~~

Further, we recognize a portion of our revenue from non-contracted third-party commercial payors. For example, during the year ended December 31, 2022 and three months ended March 31 2023, revenue from non-contracted third-party commercial payors accounted for approximately six percent of our total revenue. We have limited visibility as to when we will receive payment for our Zio ~~monitors,~~Services with non-contracted payors and we or ~~Zio~~XIFIN must appeal any negative payment decisions, which often delays collections further. Additionally, a portion of the revenue from non-contracted payors is received from patient co-pays, which we may not receive for several months following delivery of service ~~may require new 510(k) clearances, CE Mark, UKCA Mark or other premarket approvals~~ or may ~~require~~not receive at all. For revenue related to non-contracted payors, we estimate an average collection rate based on factors including historical cash collections.

As of March 31, 2023, we had an accumulated deficit of $561.3 million. We have financed our operations to date primarily through private and public offerings of equity securities and revenue generated by prescriptions of our Zio Services. We have and expect to continue to incur significant research and development, sales and marketing, regulatory, and other expenses as we expand our marketing efforts to increase the prescription of our Zio Services, expand existing relationships with physicians, obtain regulatory clearances or approvals for ~~any~~our current or future services and related devices, conduct clinical trials on our existing and future services, and develop new services or add new features to our existing Zio Services. We also expect that our general and administrative expenses will continue to increase due, among other things, to the operational and regulatory burdens applicable to medical service providers that are public companies. As a result, we expect to continue to incur operating losses in the future. These losses, among other things, may have an adverse effect on our stockholders’ equity and the value of ~~these modifications, we may be required to recall and to stop selling or marketing the Zio monitors and Zio service as modified, which could harm~~ our ~~operating results and require us to redesign our products or services.

Additionally, the UK will require the UKCA marking per new policies released by MHRA. All of these regulations cover procedures and documentation requirements for the design, testing, production, control, quality assurance, labeling, packaging, storage, shipping, and post-market surveillance of Zio monitors and associated software. We are also subject to similar state requirements and licenses, and to ongoing ISO 13485 and ISO 14971 compliance in all operations to maintain our CE Mark. In addition, we must engage in extensive recordkeeping and reporting and must make available our facilities and records for periodic announced or unannounced inspections by governmental agencies, including the FDA, state authorities, Notified Bodies and comparable agencies in other countries. Inspections may be initiated on a routine or for-cause basis. If regulatory inspections result in allegations of significant noncompliance that we are unable to address to the satisfaction of applicable regulatory authorities, it is possible that our operations could be disrupted and our manufacturing interrupted. Depending on the matters involved, failure to take adequate corrective action in response to an adverse regulatory inspection could result in, among other things, a shutdown of our manufacturing or product distribution operations, significant fines, suspension of marketing clearances and approvals, seizures, or large-scale recalls of our device, operating restrictions, warning letters, and criminal prosecutions, any of which would cause our business to suffer. Furthermore, our key component suppliers may not currently be or may not continue to be in compliance with applicable regulatory requirements, which may result in manufacturing delays for our product and cause our revenue to decline.

We are registered with the FDA as a medical device specifications developer and manufacturer. This is in addition to our CMS-regulated status as an IDTF. The FDA has broad post-market and regulatory enforcement powers. We are subject to announced or unannounced inspections by the FDA and the Food and Drug Branch of the California Department of Public Health (“CDPH”) to determine our compliance with the QSR and other regulationsacceptable terms, if at both our design and manufacturing facilities, and these inspections may include the manufacturing facilities of our suppliers. During the course of the COVID-19 pandemic, FDA in some cases utilized Remote Regulatory Assessments ("RRAs") and in July 2022 draft guidance it has indicated plans to continue using RRAs to supplement on-site inspection in the near term, while still budgeting and planning for increased in-person inspections now that most significant pandemic limitations on travel and in-person interactions have been lifted in many areas.all.

Additional financing may not be available on a ~~Notified Body~~timely basis on terms acceptable to us, or at all. Any additional financing may be dilutive to stockholders or may require us to grant a lender a security interest in our assets. The amount of funding we may need will depend on many factors, including:

•the revenue generated by our Zio Services;

•the costs, timing, and risks of delay of additional regulatory approvals;

•the expenses we incur in manufacturing, developing, selling, and marketing our Zio Services;

•our ability to scale our manufacturing operations to meet demand for the ~~EU as a medical device design developer, manufacturer,~~Zio Systems used in our current and ~~distributor. Our current E.U. Notified Body is~~ any future Zio Services or other offerings;

Such transitions carry a certain degree of uncertainty and risk of audit observations as each Notified Body may interpret and enforce the U.K. and E.U. regulations differently. Additionally, such transitions from E.U. MDD to E.U. MDR regulation require both Quality Management System and technical product assessments and are often complex, time consuming, and costly.

Our ability to use our net operating losses to offset future taxable income may be subject to certain limitations which could subject our business to higher tax liability.

Our ability to use our net operating losses (“NOLs”) to offset future taxable income may be subject to certain limitations which could subject our business to higher tax liability. We may be limited in the portion of NOL carryforwards that we can ~~take~~use in the ~~appropriate remedial steps~~future to ~~correct~~offset taxable income for U.S. federal and state income tax purposes, and federal tax credits to offset federal tax liabilities.

The statutes place a formula limit on how much NOLs and tax credits a corporation can use in a tax year after a change in ownership. Avoiding an ownership change is generally beyond our control. We could experience an ownership change that might limit our use of NOLs and tax credits in the future. In addition, realization of deferred tax assets, including NOL carryforwards, depends upon our future earnings in applicable tax jurisdictions. If we have insufficient future taxable income in the applicable tax jurisdiction for ~~management and if we experience a delay at our manufacturing facility~~any reason, including any future corporate reorganization or restructuring activities, we may be ~~unable~~limited in our ability to ~~produce Zio monitors, which would harm~~utilize some or all of our ~~business.~~net operating losses to offset such income and reduce our tax liability in that jurisdiction. See Note 10, Income Taxes to the consolidated financial statements included in our Annual Report on Form 10-K for the year ended December 31, 2022 for additional information.

~~Zio monitors may in the future be subject to product recalls that could harm our reputation.~~

The FDA and similar governmental authorities in other countries have the authority to require the recall of commercialized products in the event of material regulatory deficiencies or device defects. A government mandated or voluntary recall by us could occur as a result of component failures, manufacturing errors, design issues, labeling issues, or various regulatory compliance topics. Recalls of Zio monitors and associated software would divert managerial attention, be expensive, harm our reputation with customers and harm our financial condition and results of operations. A recall announcement would also negatively affect our stock price.

~~Healthcare reform measures could hinder or prevent the Zio service’s commercial success.~~

~~In the United States, there have been, and we expect there will continue~~There is also a risk that due to ~~be, a number of legislative and~~ regulatory changes to the healthcare system in ways that could harm our future revenues and profitability and the demand for the Zio service. Federal and state lawmakers regularly propose and, at times, enact legislation that would result in significantor changes to federal or state law, such as suspensions on the ~~healthcare system, some~~use of NOLs, or other unforeseen reasons, our existing NOLs could expire or otherwise be unavailable either in whole or in part to offset future income tax liabilities. For example, under the Coronavirus Aid, Relief, and Economic Security Act of 2020, which are intended to contain or reduce the costs of medical products and services. The Affordable Care Act contains a number of provisions, including those governing enrollment in federal healthcare programs, reimbursement changes and fraud and abuse measures, all of which will impact existing government healthcare programs and will result in the development of new programs. We face uncertainties that might result from modifications or repeal of any of theamended certain provisions of the ~~Affordable Care~~Tax Cuts and Jobs Act ~~including as a result~~(“TCJA”), NOLs arising in taxable years beginning after December 31, 2017 may offset no more than 80% of current taxable income annually for taxable years beginning after December 31, 2020. Therefore, we may be required to pay U.S. federal income taxes in future years despite the NOL carryforwards we have accumulated.

Risks Related to Other Legal and ~~future executive orders~~Regulatory Matters

We are subject to legal proceedings and ~~legislative actions. The impact of those changes on us~~government investigations that could adversely affect our business, financial condition, and ~~potential effect on the medical device industry as a whole is currently unknown. Any changes to the Affordable Care Act are likely to have an impact on our~~ results of ~~operations,~~operations.

We are involved in legal proceedings related to securities litigation and may become involved in other legal proceedings that arise from time to time in the future. For example, as discussed further in Note 8, Commitments and Contingencies, to our condensed consolidated financial statements included in this Quarterly Report on Form 10-Q, a putative securities class action lawsuit has been filed against the Company and certain current officers or former officers of the Company alleging violations of Sections 10(b) and 20(a) of the Exchange Act and SEC Rule 10b-5 promulgated thereunder.

Any claims against us, whether meritorious or not, can be time-consuming, result in costly litigation, be harmful to our reputation, require significant management attention, and divert significant resources. In addition, the expense of litigation and the timing of this expense from period to period are difficult to estimate and subject to change. Litigation and other claims are subject to inherent uncertainties and management’s view of these matters may change in the future. Given the uncertain nature of legal proceedings generally, we are not able in all cases to estimate the amount or range of loss that could result from an unfavorable outcome. We could incur judgments or enter into settlements of claims that could have a material adverse effect on our results of ~~operations. We cannot predict what other health care programs and regulations will ultimately be implemented at the federal or state level or the effect of~~operations in any ~~future legislation or regulation in the United States may have on our business.~~

~~Compliance with environmental laws and regulations could be expensive, and failure to comply with these laws and regulations could subject us to significant liability.~~

~~Our research and development and manufacturing operations may involve the use of hazardous substances and~~In addition, healthcare companies are subject to numerous investigations and inquiries by various governmental agencies.

~~Exposure to United Kingdom political developments, including the outcome of its withdrawal from membership in the European Union, could be costly and difficult to comply~~Compliance with ~~and could seriously harm our business.~~

We have based a significant portion of our non-U.S. operations in the United Kingdom. In June 2016, a referendum was held in the U.K. which resulted in a majority voting in favor of the U.K. withdrawing from the E.U. (commonly referred to as "Brexit"). Pursuant to legislation approved by the U.K. Parliament and the E.U. Parliament in January 2020, the U.K. withdrew from the E.U. with effect from 11 p.m. (GMT) on January 31, 2020 on the terms of a withdrawal agreement agreed between the U.K. and the E.U. in October 2019. On December 24, 2020, the U.K. and E.U. agreed to a trade deal (the “Trade and Cooperation Agreement”) which was ratified by the U.K. on December 30, 2020. The Trade and Cooperation Agreement is subject to formal approval by the European Parliament and the Council of the European Union before it comes into effect and has been applied provisionally since January 1, 2021. There are still a number of areas of uncertainty in connection with the future of the U.K. and its relationship with the E.U. and the application and interpretation of the Trade and Cooperation Agreement, and Brexit related matters may take several years to be clarified and resolved.For example, because a significant proportion of the regulatory framework in the U.K. is currently derived from E.U. directives and regulations, Brexit could result in material changes to the regulatory regime applicable to many of our current operations. Although the Trade and Cooperation Agreement offers U.K. and E.U. companies preferential access to each other’s markets, ensuring imported goods will be free of tariffs and quotas, economic relations between the U.K. and the E.U. will now be on more restricted terms than existed previously. Therefore, at this time, we cannot predict the impact that the Trade and Cooperation Agreement and any future agreements contemplated under the terms of the Trade and Cooperation Agreement will have on our future business efforts to commercialize our Zio service in the U.K. and E.U. Accordingly, it is possible that new terms of the Trade and Cooperation Agreement may adversely affect our operations and financial results. We are currently in the process of evaluating our own risks and uncertainties to ascertain what financial, trade, regulatory and legal implications the Trade and Cooperation Agreement could have on our operations in the U.K. and otherwise. Finally, uncertainty surrounding Brexit has contributed to recent fluctuations in the U.K. economy as a whole which could experience future disruptions. As a result, Brexit could cause financial and capital markets within and outside the U.K. or the E.U. to constrict, thereby negatively impacting our ability to finance our U. K. operations which could also have an adverse effect on our results of operations and financial condition.

~~Risks Related to Our Common Stock~~

~~Future sales and issuances of securities could negatively affect our stock price and dilute the ownership interest of our existing investors.~~

Our expected future capital requirements may depend on many factors, including expanding our customer base, the expansion of our sales force, and the timing and extent of spending on the development of our technology to increase our product offerings. If we raise additional funds by issuing equity securities, our stockholders may experience dilution. Additionally, new investors could gain rights, preferences and privileges senior to those of existing holders of our common stock. Any future debt financing into which we enter may impose upon us additional covenants that restrict our operations, including limitations on our ability to incur liens or additional debt, pay dividends, repurchase our common stock, make certain investments and engage in certain merger, consolidation or asset sale transactions. Any debt financing or additional equity that we raise may contain terms that are not favorable to us or our stockholders.

Sales or issuances of a substantial amount of securities, or the perception that such sales could occur, may cause a decline in the price of our common stock. Future resales of our common stock by our existing stockholders could cause the market price of our common stock to decline. In addition, the shares of common stock subject to outstanding options and restricted stock units under our 2016 Equity Incentive Plan and our 2016 Employee Stock Purchase Plan and the shares reserved for future issuance under both such plans may become eligible for sale in the public markets in the future, subject to certain legal and control limitations.

We may sell shares or other securities in any offering at a price per share that is less than the price per share paid by existing investors, and investors purchasing shares or other securities in the future could have rights superior to existing stockholders. The price per share at which we sell additional shares of our common stock, or securities convertible or exchangeable into common stock, in future transactions may be higher or lower than the price per share paid by existing investors.

~~The market price of our common stock may fluctuate substantially, and you could lose all or part of your investment.~~

The market price of our common stock may continue to fluctuate substantially in response to, among other things, the risk factors described in this Quarterly Report on Form 10-Q and other factors, many of which are beyond our control, including:

•~~changes in analysts’ estimates, investors’ perceptions, recommendations by securities analysts or our failure to achieve analysts’ estimates;~~

•~~quarterly variations in our or our competitors’ results of operations;~~

•~~the impact or anticipated impact of the COVID-19 pandemic on us;~~

•~~periodic fluctuations in our revenue, due in part to the way in which we recognize revenue;~~

•~~the financial projections we may provide to the public, any changes in these projections or our failure to meet these projections;~~

•general market conditions and other factors unrelated to our operating performance or the operating performance of our competitors, including deteriorating market conditions due to investor concerns regarding inflation and continuing hostilities between Russia and Ukraine, which could lead to volatility in foreign currency and capital markets;

•~~changes in reimbursement coverage and rates by current or potential payors;~~

•~~changes in CPT codes or the establishment of new CPT codes applicable to the Zio service;~~

•~~changes in operating performance and stock market valuations of other technology companies generally, or those in the medical device industry in particular;~~

•~~actual or anticipated changes in regulatory oversight of our products;~~

•~~the results of our clinical trials;~~

•~~the loss of key personnel, including changes in our board of directors and management;~~

•~~legislation or regulation affecting our market;~~

•~~lawsuits threatened or filed against us;~~

•~~the announcement of new products or product enhancements by us or our competitors;~~

•~~announced or completed acquisitions of businesses or technologies by us or our competitors;~~

•~~announcements related to patents issued to us or our competitors and to litigation; and~~

•~~developments in our industry.~~

Fluctuations in our stock price, volume of shares traded, and changes in our market valuations may make our stock less attractive to certain investors. Stockholders may file securities class action litigation following periods of market volatility. Securities litigation, like the current action we are subject to in the District Court for the Northern District of California, could subject us to substantial costs, divert resources and the attention of management from our business, and adversely affect our business, results of operations, financial condition, reputation and cash flows. These factors may materially and adversely affect the market price of our common stock.

If securities or industry analysts do not publish research or reports about our business, or if they issue adverse or misleading opinions regarding our stock, our stock price and trading volume could decline.

The trading market for our common stock will be influenced by the research and reports that industry or securities analysts publish about us or our business. If any of the analysts who cover us issue an adverse or misleading opinion regarding us, our business model, our intellectual property or our stock performance, or if our target studies and operating results fail to meet the expectations of analysts, our stock price would likely decline. If one or more of these analysts cease coverage of us or fail to publish reports on us regularly, we could lose visibility in the financial markets, which in turn could cause our stock price or trading volume to decline.

~~The~~ requirements of being a public company matters and reporting may strain our resources and divert management’s ~~attention and affect our ability to attract and retain executive management and qualified board members.~~attention.

As a public company, we are subject to ~~the reporting requirements of the Exchange Act, the Sarbanes-Oxley Act, the Dodd Frank Act, the listing requirements of The NASDAQ Stock Market~~laws and ~~other applicable securities laws, rules and regulations. Compliance with these laws, rules and~~ regulations will increase our legal and financial compliance costs, make some activities more difficult, time consuming or costly and increase demand on our systems and resources. The Exchange Act requires, among other things, that we file annual, quarterly and current reports with respect to our business and operating results. The Sarbanes-Oxley Act requires, among other things, that we maintain effective disclosure controls and procedures and internal control over financial reporting. In order to maintain and, if required, improve our disclosure controls and procedures and internal control over financial reporting to meet this standard, significant resources and management oversight may be required. As a result, our management and other personnel divert attention from operational and other business matters to devote

substantial time to these public company requirements. In particular, we incur significant expenses and devote substantial management effort toward ensuring compliance with the requirements of Section 404. We continue to hire additional accounting and financial staff with appropriate public company experience and technical accounting knowledge. We cannot predict or estimate the amount of additional costs we will incur in order to remain compliant with our public company reporting requirements or the timing of such costs. Additional compensation costs and any future equity awards will increase our compensation expense, which will increase our general and administrative expense and could adversely affect our profitability.

~~In addition, changing laws, regulations and standards~~ relating to corporate governance and public disclosure, ~~are creating uncertainty for public companies, increasing~~including the Sarbanes-Oxley Act of 2002, the Dodd-Frank Wall Street Reform and Consumer Protection Act, the rules and regulations implemented by the SEC, and The Nasdaq Stock Market listing rules. Compliance with these laws and regulations, including new laws and regulations or revisions to existing laws and regulations, has required and will continue to require substantial management time and oversight and the incurrence of significant accounting and legal ~~and financial compliance costs and making some activities more time consuming.~~costs. These laws, regulations, and standards are subject to varying interpretations, in many cases due to their lack of specificity, and, as a result, their application in practice may evolve over time as new guidance is provided by regulatory and governing bodies. This could result in continuing uncertainty regarding compliance matters and higher costs necessitated by ongoing revisions to disclosure and governance practices. We intend to continue to invest resources to comply with evolving laws, regulations, and standards, and this investment may result in increased general and administrative expenses and a diversion of management’s time and attention from ~~revenue generating~~revenue-generating activities to compliance activities. If our efforts to comply with new laws, regulations, and standards differ from the activities intended by regulatory or governing bodies due to ambiguities related to their application and practice, regulatory authorities may initiate legal proceedings against us and our business may be ~~harmed.~~adversely affected.

We could be subject to changes in our tax rates, new U.S. or international tax legislation, or additional tax liabilities.

We are subject to taxes in the United States and numerous foreign jurisdictions, where certain of our subsidiaries are organized. The tax laws in the United States and in other countries in which we and our subsidiaries do business could change on a ~~public company,~~prospective or retroactive basis, and any such changes could adversely affect our business and financial condition. Our effective tax rates could be affected by numerous factors, including changes in the mix of earnings in countries with differing statutory tax rates, changes in the valuation of deferred tax assets and liabilities, and changes in tax laws or their interpretation, both in and outside the United States.

For example, in 2017, the U.S. government enacted the TCJA, which made significant changes to the taxation of business entities, including a permanent reduction to the corporate income tax rate, changes in the taxation of foreign earnings, and limitations on the deductibility of expenses. Although we are still awaiting guidance from the Internal Revenue Service on how some of the TCJA changes will impact us, beginning in 2022, the TCJA eliminated the option to immediately deduct research and development expenditures and required taxpayers to amortize domestic expenditures over five years and foreign expenditures over fifteen years. While it is possible that Congress may modify or repeal this provision, we have no assurance that this provision will be modified or repealed and even if Congress makes any such decision, it may not be retroactive to January 1, 2022, and could still therefore result in an impact on cash from operating activities and on the balance of our deferred taxes. In addition, we have a significant presence in the United Kingdom, as well as significant sales in the United Kingdom, such that any changes in tax laws in the United Kingdom will impact our business. The overall impact of these changes is uncertain, and our business and financial condition could be adversely affected.

Our tax returns and other tax matters also are subject to examination by the U.S. Internal Revenue Service and other tax authorities and governmental bodies. We regularly assess the likelihood of an adverse outcome resulting from these examinations to determine the adequacy of our provision for taxes. We cannot guarantee the outcome of these examinations. If our effective tax rates were to increase, particularly in the United States, or in other jurisdictions implementing legislation to reform existing tax legislation, including the United Kingdom, or if the ultimate determination of our taxes owed is for an amount in excess of amounts previously accrued, our financial condition, operating results, and cash flows could be adversely affected.

We may be liable for contamination or other harm caused by materials that we handle, and changes in environmental regulations could cause us to incur additional expense.

Our research and development and manufacturing operations may involve the use or handling of hazardous materials. We are subject to a variety of federal, state, local, and international laws, rules, and regulations governing the use, handling, storage, disposal and remediation of hazardous and biological materials, as well as the sale, labeling, collection, recycling, treatment, and disposal of products containing such hazardous substances, and we incur expenses relating to compliance with these laws and regulations. If we violate environmental, health and safety laws, including as a result of human error, equipment failure, or other cases, we could face substantial liabilities, fines, and penalties, personal injury and third-party property damage claims, and substantial investigation and remediation costs. These expenses or this liability could have a significant negative impact on our financial condition. Environmental laws could become more ~~expensive~~stringent over time, imposing greater compliance costs and increasing risks and penalties associated with violations. We are subject to potentially conflicting and changing regulatory agendas of political, business, and environmental groups. Changes to or restrictions on the procedures for hazardous or biological material storage or handling might require unplanned capital investment or relocation of our facilities. Failure to comply, or the cost of complying, with new or existing laws or regulations could harm our business, financial condition, and results of operations.

Risks Related to Intellectual Property

We are subject to claims of infringement or misappropriation of the intellectual property rights of others, which could prohibit us from shipping affected devices, require us to obtain ~~director~~licenses from third parties or to develop non-infringing alternatives, and ~~officer liability insurance,~~subject us to substantial monetary damages and injunctive relief.

We rely on a combination of patents, copyrights, trademarks, trade secret laws, and confidentiality and invention assignment agreements with employees and third parties to protect our intellectual property rights. Our patents and patent applications are directed to covering key aspects of the design, manufacture and use of our Zio Services, including our Zio Systems.

Third parties may assert infringement or misappropriation claims against us with respect to our current or future Zio Services, including our Zio Systems. We are aware of numerous patents issued to third parties that may relate to aspects of our business, including the design and manufacture of the Zio Systems used in connection with our Zio Services. Whether a product infringes a patent involves complex legal and factual issues, the determination of which is often uncertain. Therefore, we cannot be certain that we have not infringed the intellectual property rights of such third parties or others. Our competitors may assert that our Zio Systems or the methods we employ to deliver our Zio Services are covered by U.S. or foreign patents held by them and we may be required to ~~accept reduced coverage~~settle such allegations in the future. This risk is exacerbated by the fact that there are numerous issued patents and pending patent applications relating to remote cardiac monitoring services and the associated devices. There may be existing patents or patent applications now pending of which we are unaware that may later result in issued patents that our Zio Services, including our Zio Systems, inadvertently infringe. As the number of competitors in the remote cardiac monitoring market grows, the possibility of patent infringement by us or a patent infringement claim against us increases. If we are unable to successfully defend any such claims as they may arise or enter into or extend settlement and license agreements on acceptable terms or at all, our business operations may be harmed.

Any infringement or misappropriation claim could cause us to incur ~~substantially higher~~significant costs, place significant strain on our financial resources, divert management’s attention from our business, and harm our reputation. In addition, if the relevant patents are upheld as valid and enforceable and we are found to infringe such patents, we could be prohibited from using any portion of our Zio Services, including our Zio Systems, that is found to infringe such patent unless we could obtain licenses to use the technology covered by the patent or are able to design around the patent. We may be unable to obtain ~~coverage. These factors~~a license on terms acceptable to us, if at all, and we may not be able to redesign our Zio Services, including our Zio Systems, to avoid infringement. We may be unable to maintain or renew licenses on terms acceptable to us, if at all, and we may be prohibited from selling any portion of our Zio Services, including our Zio Systems, that required the technology covered by the relevant licensed patents. Although patent and intellectual property disputes in the healthcare and medical devices area have often been settled through licensing or similar arrangements, costs associated with such arrangements may be substantial and would likely include ongoing royalties. Even if we are able to redesign our Zio Services, including our Zio Systems, to avoid an infringement claim, we may not receive FDA approval for such changes in a timely manner or at all.

Further, if we are found to infringe third-party patents, a court could ~~also make it more difficult for~~order us to ~~attract~~pay damages to compensate the patent owner for the infringement, such as a reasonable royalty amount and/or profits lost by the patent owners, along with prejudgment and/or post-judgment interest. Furthermore, if we are found to willfully infringe third-party patents, we could, in addition to other penalties, be required to pay treble damages; and ~~retain qualified executive officers~~if the court finds the case to be exceptional, we may be required to pay attorneys’ fees for the prevailing party. If we are found to infringe third-party copyrights or trademarks or misappropriate third-party trade secrets, based on the intellectual property at issue, a court could order us to pay statutory damages, actual damages, or profits, such as reasonable royalty or lost profits of the owners, unjust enrichment, disgorgement of profits, and/or a reasonable royalty, and ~~members~~the court could potentially award attorneys’ fees or exemplary or enhanced damages. If litigation were to be initiated by intellectual property owners, there could significant legal fees and costs incurred in defending litigation (which may include filing administrative actions to attack the intellectual property) as well as a potential monetary settlement payment to the owners, even if the matter is resolved before going to trial. Moreover, the owners may take an overly aggressive approach and/or include multiple allegations in a single litigation.

Our inability to adequately protect our intellectual property could allow our competitors and others to produce devices and offer services based on our technology, which could substantially impair our ability to compete.

Our success and our ability to compete depend, in part, upon our ability to maintain the proprietary nature of our ~~board~~technologies. We rely on a combination of ~~directors, particularly~~patent, copyright, and trademark law, and trade secrets and nondisclosure agreements to ~~serve~~protect our intellectual property. However, such methods may not be adequate to protect us or permit us to gain or maintain a competitive advantage.

For example, our patent applications may not issue as patents in a form that will be advantageous to us, or at all. Our issued patents, and those that may issue in the future, may be challenged, invalidated, or circumvented, which could limit our ability to stop competitors from marketing related devices and services. In addition, there are numerous recent changes to the patent laws and proposed changes to the rules of the USPTO, which may have a significant impact on our ~~audit committee~~ability to protect our technology and ~~compensation committee.~~enforce our intellectual property rights. We also may not be able to prevent the unauthorized disclosure or use of our technical knowledge or other trade secrets by consultants, vendors or former or current employees, despite the existence generally of invention assignment and confidentiality agreements and other contractual restrictions we include in contracts with such parties. These agreements may not provide meaningful protection for our trade secrets, know-how, or other proprietary information in the event of any unauthorized use, misappropriation, or disclosure of such trade secrets, know-how, or other proprietary information. There can be no assurance that employees, consultants, vendors, and clients have executed such agreements or have not breached or will not breach their agreements with us, that we will have adequate remedies for any breach, or that our trade secrets will not otherwise become known or independently developed by competitors. In addition, ~~compliance~~we rely on trademarks, service marks, trade names and brand names, such as our registered trademark “ZIO,” to distinguish our products from the products of our competitors, and have registered or applied to register these trademarks. We cannot assure you that our trademark applications will be approved. Further, during trademark registration proceedings, we may receive rejections. Although we are given an opportunity to respond to those rejections, we may be unable to overcome such rejections. In addition, in proceedings before the USPTO and in proceedings before comparable agencies in many foreign jurisdictions, third parties are given an opportunity to oppose pending trademark applications and to seek to cancel registered trademarks. Opposition or cancellation proceedings may be filed against our trademarks, and our trademarks may not survive such proceedings. Additionally, we are aware of at least one third party that has registered the “IRHYTHM” mark in the European Union in connection with ~~applicable rules~~computer software for controlling and ~~regulations~~managing patient medical information, heart rate monitors, and heart rate monitors to be worn during moderate exercise, among other uses. We and the third party are involved in adversary proceedings before the Trademark Office in the European Union, and those proceedings could impact our ability to obtain a European Union trade mark registration for ~~public companies~~the “IRHYTHM” mark, although we already own many national registrations for IRHYTHM in Europe.

To protect our proprietary rights, we may in the future need to assert claims of infringement against third parties. The outcome of litigation to enforce our intellectual property rights in patents, copyrights, trade secrets, or trademarks is ~~generally~~highly unpredictable, could result in substantial costs and diversion of resources, and could have a material adverse effect on our business, financial condition, and results of operations regardless of the final outcome of such litigation. In the event of an adverse judgment, a court could hold that some or all of our asserted intellectual property rights are not infringed, or are invalid or unenforceable, and could award attorneys’ fees.

Despite our efforts to safeguard our unpatented and unregistered intellectual property rights, we may not succeed in doing so or the steps taken by us in this regard may not be adequate to detect or deter misappropriation of our technology or to prevent an unauthorized third party from copying or otherwise obtaining and using our devices, technology or other information that we regard as proprietary. In addition, third parties may be able to design around our patents. Furthermore, the laws of foreign countries may not protect our proprietary rights to the same extent as the laws of the United States.

Risks Related to Privacy and Security

Cybersecurity risks, including those involving network security breaches and services interruptions, could result in the compromise of confidential data or critical data systems and give rise to potential harm to our patients, remediation and other expenses, expose us to liability under HIPAA, breach notification laws, consumer protection laws, or other common law theories, subject us to litigation and federal and state governmental inquiries, damage our reputation, and otherwise be disruptive to our business and operations.

Cybersecurity threats can come from a variety of sources, ranging in sophistication from an individual hacker to malfeasance by employees, consultants or other service providers to criminal or other unauthorized threat actors, including state-sponsored attacks. Unauthorized parties may also attempt to gain access to our systems or facilities through fraud, trickery or other forms of deceiving our employees, contractors and temporary staff. Cyber threats may be generic, or they may be custom-crafted against our information systems. Cyber incidents can result from deliberate attacks or unintentional events. Over the past several years, cyber-attacks have become more ~~expensive than it is for private companies.~~prevalent and much harder to detect and defend against. These threat actors may be able to penetrate our security measures, breach our information technology systems, misappropriate or compromise confidential and proprietary information of our company, customers, and patients, cause system disruptions and shutdowns, or introduce ransomware, malware, or vulnerabilities into our devices, systems, and networks or those of our partners. Our network and storage applications, as well as those of our contractors, may be vulnerable to cyber-attack, malicious intrusion, malfeasance, loss of data or other significant disruption and may be subject to unauthorized access by hackers, employees, consultants or other service providers. In addition, hardware, software or applications we develop or procure from third parties may contain defects in design or manufacture or other problems that could unexpectedly compromise information security or other problems that unexpectedly could interfere with our business operations. Because the techniques used to obtain unauthorized access, disable or degrade service, or sabotage systems change frequently and may not immediately produce signs of intrusion, we may be unable to anticipate these incidents or techniques, timely discover them, or implement adequate preventative measures.

We have in the past been subject to cyber-attacks and data breaches and expect that we will be subject to additional cyber-attacks in the future and may experience future data breaches. Such incidents may impact the integrity, availability or confidentiality of the sensitive data we maintain or disrupt our information systems, devices or business, including our ability to deliver our services. As a result, cybersecurity, physical security and the continued development and enhancement of ~~disclosure of~~our controls, processes and practices designed to protect our enterprise, information ~~in this filing~~systems and ~~in other filings~~data from attack, damage or unauthorized access remain a priority for us. As cyber threats continue to evolve, we may be required ~~of a public company,~~to expend significant additional resources to continue to modify or enhance our ~~business~~protective measures or to investigate and ~~financial condition is more visible, which could be advantageous~~remediate any cybersecurity vulnerabilities.

We are subject to ~~our competitors~~complex and evolving U.S. and foreign laws and regulations and other ~~third parties~~requirements regarding privacy, data protection, security, and other matters. Many of these laws and regulations are subject to change and uncertain interpretation, and could result in ~~threatened~~claims, changes to our business practices, monetary penalties, increased cost of operations, or ~~actual litigation. If~~declines in user growth or engagement, or otherwise harm our business.

In the ordinary course of our business, we collect and store sensitive data, such ~~claims~~as our proprietary business information and that of our suppliers, contractors, customers, vendors and others, as well as personal information, including health information, of these parties and of our patients. As a result, we are ~~successful,~~subject to several foreign, federal and state laws and regulations protecting the use, disclosure and confidentiality of certain personal information, namely individually identifiable information (e.g., names, social security numbers, addresses, birth dates), and restricting the use and disclosure of that information. These laws include foreign, federal and state healthcare privacy laws, telehealth laws, breach notification laws and consumer protection laws. These frameworks impose stringent privacy and security standards and potentially significant non-compliance penalties and liability. Foreign data protection, privacy, and related laws and regulations can be more restrictive than those in the United States. For example, data localization laws in some countries generally mandate that certain types of data collected in a particular country be stored and/or processed solely within that country. In addition, both foreign and U.S. legislators and regulators may make legal and regulatory changes, or interpret and apply existing laws, in ways that require us to incur substantial costs, expose us to unanticipated civil or criminal liability, or cause us to change our business practices. These changes or increased costs could negatively impact our business and ~~operating~~ results of operations in material ways.

The secure maintenance, processing and transmission of this sensitive information is critical to our business operations, particularly as we are increasingly dependent on sophisticated information technology systems to operate our business. System failures or outages, including any potential disruptions due to significantly increased global demand on certain cloud-based systems during or as a result of the COVID-19 pandemic, or failures to adequately scale our data platforms and architectures support patient care could compromise our ability to perform these functions in a timely manner, which could harm our ability to conduct business or delay our financial reporting. We have implemented multiple layers of security measures and monitoring to protect the confidentiality, integrity and availability of this data and the systems and devices that store and transmit such data. Despite our security measures and business controls, which undergo routine testing internally and by external parties, our information technology and infrastructure may be vulnerable to attacks by hackers, breaches due to employee, contractor or vendor error, or malfeasance or other disruptions or subject to the inadvertent or intentional unauthorized release of information. Any such occurrence could compromise our data centers and networks and the information stored thereon could be ~~harmed,~~inappropriately accessed, publicly disclosed, lost or stolen. Further, any such access, disclosure or other loss of information could result in legal claims or proceedings, and ~~even~~liability under laws that protect the privacy of personal information and regulatory penalties, increase in operating expenses, incurrence of expenses, including notification and remediation costs, disrupt our operations and the services we provide to our clients or damage our reputation, any of which could adversely affect our profitability, revenue and competitive position.

Cyber-attacks aimed at accessing our devices and services, or related devices and services, and modifying or using them in a way inconsistent with our FDA clearances and approvals, could create risks to users.

Medical devices are increasingly connected to the Internet, hospital networks, and other medical devices to provide features that improve healthcare and increase the ability of healthcare providers to treat patients and of patients to manage their conditions. As such, cyber-attacks aimed at accessing our devices and services, or related devices and services, and modifying or using them in a way inconsistent with our FDA clearances and approvals, may create risks to users and potential exposure to the company.

Risks Related to Our Common Stock

If securities or industry analysts do not publish research or reports about our business, or if they issue an adverse or misleading opinion regarding our stock, our stock price and trading volume could decline.

The trading market for our common stock will be influenced by the ~~claims are resolved~~research and reports that industry or securities analysts publish about us or our business. We do not have any control over the analysts, or the content and opinions included in their reports. If any of the analysts who cover us issues an adverse or misleading opinion regarding us, our business model, our intellectual property, or our stock performance, or if any third-party preclinical studies and clinical trials involving our Zio Services or our results of operations fail to meet the expectations of analysts, our stock price would likely decline. If one or more of such analysts cease coverage of us or fail to publish reports on us regularly, we could lose visibility in the financial markets, which in turn could cause a decline in our ~~favor, these claims,~~stock price or trading volume.

Our stock price is highly volatile and investing in our stock involves a high degree of risk, which could result in substantial losses for investors.

Historically, the market price of our common stock, like the securities of many other medical service providers that are public companies, has fluctuated. It is likely that our stock price will continue to be volatile in the future. In addition, the trading prices for our common stock and the ~~time~~common stocks of other medical service providers been highly volatile as a result of macroeconomic conditions, including inflation, rising interest rates, and ~~resources necessary to resolve them, could divert~~ the ~~resources~~persisting impacts of the COVID-19 pandemic and the ongoing military conflict between Russia and Ukraine.

The market price of our ~~management~~common stock is influenced by many factors that are beyond our control, including the following:

•securities analyst coverage or lack of coverage of our common stock or changes in their estimates of our financial performance;

•variations in quarterly operating results;

•future sales of our common stock by our stockholders;

•investor perception of us and ~~harm~~ our industry;

•announcements by us or our competitors of significant agreements, acquisitions, or capital commitments or service or product launches or discontinuations;

•changes in market valuation or earnings of our competitors;

•negative business or financial announcements regarding our partners;

•general economic conditions;

•regulatory actions;

•legislation and political conditions;

•global health pandemics, such as the COVID-19 pandemic;

•terrorist acts, acts of war, or periods of widespread civil unrest, including the ongoing military conflict between Russia and Ukraine and actions taken by third parties in response to such conflict; and

•general economic, industry, and market conditions, including inflation, rising interest rates, and foreign currency exchange rates.

Please also refer to the factors described elsewhere in this “Risk Factors” section. In addition, the stock market in general has experienced extreme price and volume fluctuations that have often been unrelated and disproportionate to the operating ~~results.~~performance of companies in our industry. These broad market and industry factors may materially reduce the market price of our common stock, regardless of our operating performance.

Securities class action litigation has often been brought against public companies that experience periods of volatility in the market prices of their securities. Securities class action litigation could result in substantial costs and a diversion of our management’s attention and resources.

Anti-takeover effects of our charter documents and Delaware law could make a merger, tender offer, or proxy contest difficult, thereby depressing the trading price of our common stock.

There are provisions in our amended and restated certificate of incorporation and amended and restated bylaws, ~~and~~as well as provisions in the Delaware ~~law, could~~General Corporation Law (“DGCL”), that may discourage, delay, or prevent a change inof control of our company that might otherwise be beneficial to stockholders. These provisions could also make it difficult for stockholders to elect directors who are not nominated by current members of our board of directors or ~~a change~~take other corporate actions, including effecting changes in our management.

~~Our amended and restated certificate of incorporation and bylaws contain provisions that might enable our management to resist a takeover. These provisions include:~~ For example:

•~~advance notice requirements applicable to~~our board of directors may, without stockholder approval, issue shares of preferred stock with special voting or economic rights;

•our stockholders ~~for matters to~~do not have cumulative voting rights and, therefore, each of our directors can only be ~~brought before a meeting of stockholders and requirements as to the form and content~~elected by holders of a ~~stockholders’ notice;~~majority of our outstanding common stock;

•a ~~supermajority stockholder vote requirement for amending certain provisions~~special meeting of ~~our amended and restated certificate of incorporation and bylaws;~~

•~~the right to issue preferred stock without stockholder approval, which could be used to dilute the stock ownership of a potential hostile acquirer;~~

•~~allowing stockholders to remove directors only for cause;~~

•~~a requirement that the authorized number of directors may be changed only by resolution of the board of directors;~~

•allowing all vacancies, including newly created directorships, to be filled by the affirmative vote of a majority of directors then in office, even if less than a quorum, except as otherwise required by law;

•~~a requirement that our~~ stockholders may only ~~take action at annual or special meetings of our stockholders and not~~be called by ~~written consent;~~

•we require advance notice for nominations for election to the board of directors or for proposing matters that can be acted upon by stockholders at stockholder meetings.

~~These provisions might~~Moreover, Section 203 of the DGCL may discourage, delay, or prevent a change inof control of our ~~company or a change in our management. The existence of these provisions could adversely affect the voting power of~~company. Section 203 imposes certain restrictions on mergers, business combinations, and other transactions between us and holders of ~~common stock and limit the price that investors might be willing to pay in the future for shares~~15% or more of our common stock. In addition, because we are incorporated in Delaware, we are governed by the provisions of Section 203 of the Delaware General Corporation Law, which generally prohibits a Delaware corporation from engaging in any of a broad range of business combinations with any “interested” stockholder for a period of three years following the date on which the stockholder became an “interested” stockholder.

Our amended and restated certificate of incorporation and bylaws provide that the Court of Chancery of the State of Delaware (or, if the Court of Chancery does not have jurisdiction, another State court in Delaware or the federal district court for the District of Delaware) will be the sole and

The exclusive forum ~~for substantially all disputes between us and~~provision in our ~~stockholders, which could limit our stockholders’ abilities to obtain a favorable judicial forum for disputes with us or our directors, officers or employees.~~

Our amended and restated certificate of incorporation and bylaws provide that, unless we consent to the selection of an alternative forum, the Court of Chancery of the State of Delaware (or, if the Court of Chancery does not have jurisdiction, another State court in Delaware or the federal district court for the District of Delaware) is the sole and exclusive forum for (i) any derivative action or proceeding brought on our behalf, (ii) any action asserting a claim of breach of fiduciary duty owed by any of our directors, officers or other employees to us or to our stockholders, (iii) any action asserting a claim against the company or any director or officer of the company arising pursuant to the Delaware General Corporation Law, our amended and restated certificate of incorporation or bylaws, (iv) any action to interpret, apply, enforce or determine the validity of our amended and restated certificate of incorporation or bylaws, or (v) any action asserting a claim against us governed by the internal affairs doctrine, in each such case subject to said Court of Chancery having personal jurisdiction over the indispensable parties named as defendants therein. This provision would not apply to suits brought to enforce a duty or liability created by the Exchange Act or any other claim for which the U.S. federal courts have exclusive jurisdiction. Our investors cannot waive compliance with the federal securities laws and the rules and regulations thereunder. Our bylaws further provide that the federal district courts of the United States will be the exclusive forum for resolving any complaint asserting a cause of action arising under the Securities Act. The enforceability of similar exclusive federal forum provisions in other companies’ organizational documents has been challenged in legal proceedings, and while the Delaware Supreme Court has ruled that this type of exclusive federal forum provision is facially valid under Delaware law, there is uncertainty as to whether other courts would enforce such provisions. The choice of forum provision may limit a stockholder’s ability to bring a claim in a judicial forum that it finds favorable for disputes with us or any of our directors, officers, or other employees, or the underwriters of any offering giving rise to such claim, which may discourage lawsuits with respect to such claims.

Our amended and restated certificate of incorporation provides that, to the fullest extent permitted by law, the Court of Chancery of the State of Delaware is the exclusive forum for: any derivative action or proceeding brought on our behalf; any action asserting a claim of breach of fiduciary duty owed by any director, officer, or other employee or agent of the company to us or our stockholders; any action asserting a claim against us arising pursuant to any provision of the DGCL, our amended and restated certificate of incorporation, or our amended and restated bylaws; any action to interpret, apply, enforce or determine the validity of our amended and restated certificate of incorporation, or our amended and restated bylaws; or any action asserting a claim against us that is governed by the internal affairs doctrine. This exclusive forum provision does not apply to suits brought to enforce a duty or liability created by the Exchange Act.

Notwithstanding the foregoing, our stockholders will not be deemed to have waived our compliance with the federal securities laws and the regulations promulgated thereunder. Any person or entity purchasing or otherwise acquiring or holding any interest in any of our securities shall be deemed to have notice of and consented to our exclusive forum provisions. The exclusive forum provisions may limit a stockholder’s ability to bring a claim in a judicial forum that it finds favorable for disputes with us or any of our directors, officers, or other employees, which may discourage lawsuits with respect to such ~~lawsuits against us and our directors, officers and other employees.~~claims.

Risks Related to Our Debt

Increasing our ~~earnings, capital requirements,~~ financial ~~condition, prospects~~leverage could affect our operations and ~~other factors our board~~profitability.

We are party to a Third Amended and Restated Loan and Security Agreement, dated as of ~~directors may deem relevant. In addition, our loan agreement~~October 23, 2018, with Silicon Valley Bank ~~limits~~(as amended by the Second Amendment to Third Amended and Restated Loan and Security Agreement, dated as of March 28, 2022, the “SVB Loan Agreement”), which provides for a (i) a revolving line of credit in the aggregate principal amount of up to $25.0 million and (ii) a term loans facility in the aggregate principal amount of up to $75.0 million. As of March 31, 2023, we had nothing outstanding under the revolving credit line and $35.0 million outstanding under the term loans.

Our leverage ratio, combined with our other financial obligations and contractual commitments, may affect our ability to ~~among~~obtain additional capital resources as well as our operations in several ways, including:

•the possible lack of availability of additional credit;

•the terms on which credit may be available to us could be less attractive, both in the economic terms of the credit and the legal covenants;

•the potential for higher levels of interest expense to service or maintain our outstanding debt;

•the possibility that we are required to incur additional debt in the future to repay our existing indebtedness when it comes due;

•the possibility that our level of indebtedness make us more vulnerable to adverse changes in general U.S. and worldwide economic, industry, and competitive conditions and adverse changes in government regulation;

•limiting our ability to borrow additional amounts to fund acquisitions, for working capital, and for other ~~things, pay dividends or make~~general corporate purposes;

•the possible diversion of capital resources from other ~~distributions or payments on account~~uses; and

•making an acquisition of our ~~common stock,~~company less attractive or more difficult.

Any of these factors could harm our business, results of operations, and financial condition. While we believe we will have the ability to service our obligations under the SVB Loan Agreement and obtain additional financing in the future if and when needed, that will depend upon our results of operations and financial position at the time, the then-current state of the credit and financial markets, and other factors that may be beyond our control. Therefore, we cannot give assurances that sufficient credit will be available on terms that we consider attractive, or at all, if and when necessary or beneficial to us.

Failure to comply with covenants in the SVB Loan Agreement could result in our inability to borrow additional funds and adversely impact our business.

The SVB Loan Agreement imposes numerous financial and other restrictive covenants on our operations, including financial covenants. As of March 31, 2023, we were in material compliance with the covenants imposed by the SVB Loan Agreement. If we violate these or any other covenants under the SVB Loan Agreement or fail to make payments in connection therewith, Silicon Valley Bank could declare an event of default, which would give it the right to terminate its commitment to provide additional loans and declare all borrowings outstanding, together with accrued and unpaid interest and fees, to be immediately due and payable. In addition, Silicon Valley Bank would have the right to proceed against the assets we provided as collateral pursuant to the loan. Any of the foregoing may limit our ability to borrow additional funds and pursue other business opportunities or strategies that we would otherwise consider to be in our best interests.

Servicing our debt requires a significant amount of cash, and we may not have sufficient cash flow from our business to pay our substantial debt.

Our ability to make scheduled payments of the principal of, to pay interest on, or to refinance our indebtedness, including the SVB Loan Agreement, depends on our future financial condition and operating performance, which is subject to ~~certain exceptions.~~ economic, financial, competitive, and other factors beyond our control. Our business may not generate cash flow from operations in the future sufficient to satisfy our obligations under the SVB Loan Agreement and any future indebtedness we may incur and to make necessary capital expenditures.

If we are unable to generate such cash flow, we may be required to adopt one or more alternatives, such as reducing or delaying investments or capital expenditures, selling assets, refinancing, or obtaining additional equity capital on terms that may be onerous or highly dilutive. These alternative measures may not be successful and may not permit us to meet our scheduled debt servicing obligations. Further, we may need to refinance all or a portion of our debt on or before maturity, and our ability to refinance the SVB Loan Agreement or any future indebtedness will depend on the capital markets and our financial condition at such time. We may not be able to engage in any of these activities on commercially reasonable terms or at all, which could result in a default under the SVB Loan Agreement or any future indebtedness.

General Risk Factors

We may be impacted by domestic and global economic and political conditions, as well as natural disasters, pandemics, and other catastrophic events, which could adversely affect our business, financial condition or results of operations.

Our operations and performance may vary based on worldwide economic and political conditions, which have been adversely impacted by continued global economic uncertainty, political instability, and military hostilities in multiple geographies, including the COVID-19 pandemic, the ongoing military conflict between Russia and Ukraine, domestic and global inflationary trends, rising interest rates, instability in the global banking system, global supply shortages, and a tightening labor market. For example, we have experienced staff shortages at our contact centers as a result of the COVID-19 pandemic and federal, state and local responses thereto. A severe or prolonged economic downturn or period of global political instability could drive hospitals and other healthcare professionals to tighten budgets and curtail spending, which could in turn negatively impact rates at which physicians prescribe our Zio Services. In addition, higher unemployment rates or reductions in employer-provided benefits plans could result in fewer commercially insured patients, resulting in a reduction in our margins and impairing the ability of uninsured patients to make timely payments. A weak or declining economy could also strain our suppliers, possibly resulting in supply delays and disruptions. There is also a risk that one or more of our current service providers, suppliers, or other partners may not survive such difficult economic times, which could directly affect our ability to attain our goals on schedule and on budget. If the current equity and credit markets deteriorate, it may make any necessary debt or equity financing more difficult, more costly, and more dilutive. We cannot predict the timing, strength, or duration of an economic downturn, instability, or recovery, whether worldwide, in the United States, or within our industry.

In addition, climate-related events, including the increasing frequency of extreme weather events, natural disasters, or other catastrophic events may cause damage or disruption to our operations, international commerce, and the global economy, and could have an adverse effect on our business, operating results, and financial condition. In the event of a natural disaster, including a major earthquake, blizzard, or hurricane, or a catastrophic event such as a fire, power loss, cyberattack, or telecommunications failure, we may be unable to continue our operations and may endure system and service interruptions, reputational harm, delays in development of our Zio Systems and Zio Services, breaches of data security, and loss of critical data, all of which could cause us to experience higher attrition, losses, and additional costs to maintain or resume operations, or otherwise have an adverse effect on our business and operating results. Further, we do not ~~pay dividends,~~maintain insurance sufficient to compensate us for the potentially significant losses that could result from disruptions to our ~~stock~~services. Additionally, all the aforementioned risks may be ~~less valuable because a return on your investment will only occur~~further increased if our ~~stock price appreciates~~or our partners’ disaster recovery plans are inadequate.

Environmental, social, and ~~you sell~~corporate governance (“ESG”) regulations, policies, and provisions may make our ~~common stock thereafter.~~supply chain more complex and may adversely affect our relationships with customers.

There is an increasing focus from certain investors, physicians, patients, employees, and other stakeholders concerning corporate citizenship and sustainability matters and the governance of environmental and social risks. An increasing number of participants in the medical services industry are joining voluntary ESG groups or organizations, such as the Responsible Business Alliance. These ESG provisions and initiatives are subject to change, can be unpredictable, and may be difficult and expensive for us to comply with, given our reliance on our supply chain and the outsourced manufacturing of certain components and sub-assemblies of the Zio Systems used with our Zio Services.

Further, we have in the past and may continue to communicate certain initiatives, including goals, regarding environmental matters, responsible sourcing and social investments. We could fail, or be perceived to fail, in our achievement of such initiatives or goals, or we could fail in fully and accurately reporting our progress on such initiatives and goals. In addition, we could be criticized for the scope of such initiatives or goals or perceived as not acting responsibly in connection with these matters.

If we are not effective in addressing ESG matters affecting our business, or setting and meeting relevant ESG goals, our reputation and financial results may suffer.
