In April 2020, we announced that we received regulatory approval in Europe such that the Eversense XL is no longer contraindicated for MRI, which means the sensor does not need to be removed from under the skin during MRI scanning. We had previously obtained this indication for Eversense in the United States in 2019. This MRI approval is a first for the CGM category as all other sensors are required to be removed during an MRI scan.

​

During 2020 we initiated a new commercialization strategy and collaboration to bring our product to market. As described in detail below, in August 2020, we entered into a collaboration and commercialization agreement with Ascensia Diabetes Care Holdings AG, or Ascensia, pursuant to which we granted Ascensia the exclusive right to distribute our 90-day Eversense continuous glucose monitoring system and our 180-day Eversense continuous glucose monitoring system worldwide, with certain initial exceptions. While Ascensia is responsible for sales, marketing, market access, patient and provider onboarding and first level customer support, we remain responsible for product development and manufacturing, including regulatory submissions, approvals and registrations and second level customer support.

​

2020 and Significant Recent Developments

​

​

COVID-19

​

On January 30, 2020, the World Health Organization, or the WHO, announced a global health emergency because of a new strain of coronavirus, or COVID-19, and the risks to the international community as the virus spreads globally. On March 11, 2020, the WHO classified the COVID-19 outbreak as a pandemic, based on the rapid increase in exposure globally. In response to the pandemic, many states and jurisdictions issued stay-at-home orders and other measures aimed at slowing the spread of the coronavirus. The state of Maryland, where we are headquartered, has been affected by COVID-19. The Governor of Maryland issued an order closing all non-essential businesses, which took effect on March 23, 2020. Although the state of Maryland is gradually undergoing a phased reopening plan, substantially all of our workforce is still working from home either all or substantially all of the time. Additionally, because our sensor requires an in-clinic procedure, we saw a reduction in access to clinics and sensor insertions during the initial outbreak.

​

During the latter half of 2020, several new order requests from our distributors led to adjustments to concession allowances previously provided to some of our customers in the United States to reflect actual product usage. While these trends are promising, insertion volumes are still below pre-COVID-19 levels. Additionally, the COVID-19 pandemic infection rates in the United States are still high, vaccine distribution has only just begun, and it is difficult to predict the longevity and severity COVID-19 will have on our business.

​

Restructuring and Transition of Commercial Strategy

​

As a result of the COVID-19 pandemic’s disruption to our operations, suppliers, employees, and the healthcare community in which we sell to and support, and our limited cash resources, we made significant reductions in our cost structure and operations to improve cash flow and generate future expenditure savings to ensure the long-term success of Eversense. Specifically, in the first quarter of 2020, we temporarily suspended commercial sales and marketing of the Eversense CGM System in the United States to new patients to solely focus our resources on supporting existing users, including ensuring broader insurance coverage for Eversense, and the development and regulatory submission of our new 180-day Eversense product in the United States. In connection with these actions, on March 26, 2020, we reduced our workforce by approximately 60%, over half of which were sales personnel.

​

On August 9, 2020, we entered into a collaboration and commercialization agreement with Ascensia pursuant to which we granted Ascensia the exclusive right to distribute our 90-day Eversense continuous glucose monitoring system and our 180-day Eversense continuous glucose monitoring system worldwide for people with diabetes, with the following initial exceptions: (i) until January 31, 2021, the territory did not include countries covered by our then existing distribution agreement with Roche Diagnostics International AG and Roche Diabetes Care GmbH, which are the Europe, Middle East and Asia, excluding Scandinavia and Israel, and 17 additional countries, including Brazil, Russia, India and China, as well as select markets in the Asia Pacific and Latin American regions; (ii) until September 13, 2021, the territory does not include countries covered by our current distribution agreement with Rubin Medical, which are

Sweden, Norway and Denmark; and (iii) until May 31, 2022, the territory does not include Israel. Pursuant to the Commercialization Agreement, in the United States, Ascensia began providing sales support for the 90-day Eversense product on October 1, 2020 and the parties have been planning and making arrangements for Ascensia to ramp up sales activities and more fully assume commercial responsibilities in the second quarter of 2021. The Eversense 180-day product is planned to be marketed upon receipt of marketing approval from the FDA. In Germany, Italy and Switzerland, Spain, Poland and the Netherlands, Ascensia assumed commercial responsibilities for Eversense XL beginning on February 1, 2021. For Sweden and Norway, Ascensia will assume commercial responsibilities later this year. Ascensia is entitled to receive a portion of net revenue at specified tiered percentages ranging from the mid-teens to the mid-forty’s based on levels of global net revenues. Ascensia is obligated to achieve specified minimum annual revenue targets and meet specified levels of sales and marketing spend in order to maintain its exclusive distribution rights. Ascensia purchases Eversense and Eversense XL from us at negotiated prices. We remain responsible for product development and manufacturing, including regulatory submissions, approvals and registrations and second level customer support, and Ascensia is responsible for sales, marketing, market access, patient and provider onboarding and first level customer support. We have agreed to establish a joint alliance committee and joint marketing committee, each with equal representation from each party, in order to collaborate.

Background

​

Diabetes is a chronic, life-threatening disease for which there is no known cure. The disease is caused by the body's inability to produce or effectively utilize the hormone insulin, which prevents the body from adequately regulating blood glucose levels. If diabetes is not managed properly, it can lead to serious health conditions and complications, including heart disease, limb amputations, loss of kidney function, blindness, seizures, coma and even death. According to the 2019 International Diabetes Federation, or IDF, Atlas, an estimated 463 million people worldwide had diabetes as of the date of the report. The number of people with diabetes worldwide is estimated to grow to 700 million by 2045, driven primarily by growth in type 2 diabetes and due to various reasons, including changes in dietary trends, an aging population and increased prevalence of the disease in younger people. Diabetes is typically classified into two primary types. Type 1 diabetes is an autoimmune disorder that usually develops during childhood and is characterized by the inability of the body to produce insulin, resulting from destruction of the insulin producing beta cells of the pancreas. Type 2 diabetes is a metabolic disorder that results when the body is unable to produce sufficient amounts of insulin or becomes insulin resistant. People with type 1 diabetes must administer insulin, either by injection or insulin pump, to survive. People with type 2 diabetes may require diet and nutrition management, exercise, oral medications or the administration of insulin to regulate blood glucose levels. In the next few years, we expect the growth in sales of CGM systems to be driven primarily by increased penetration of CGM in the type 1 patient population.

​

In an attempt to maintain blood glucose levels within the normal range, many people with diabetes seek to actively monitor their blood glucose levels. The traditional self-monitoring of blood glucose, or SMBG, method of glucose monitoring requires lancing the fingertips, commonly referred to as fingersticks, multiple times per day and night to obtain a blood drop to be applied to a test strip inside a blood glucose meter. This method of monitoring glucose levels is inconvenient and can be painful and, because each measurement represents a single blood glucose value at a single point in time, it provides limited information regarding trends in blood glucose levels. In contrast, CGM systems are generally less painful and involve the insertion of sensors into the body to measure glucose levels in the interstitial fluid throughout the day and night, providing real-time data that shows trends in glucose measurements. As a result, CGMs improve glycemic control and quality of life, particularly in patients with type 1 diabetes treated with continuous subcutaneous insulin infusion or multiple daily insulin injection therapy, and support avoidance of hypoglycemia.

​

Historically, the FDA and other device regulators required that CGMs be labeled and marketed as "adjunctive" to test-strip measurements, with instructions that patients confirm CGM measurements with test-strip measurements using blood obtained from fingersticks prior to self-medicating. However, given the broader clinical indications for the use of CGM systems, including real-time alerts and multi-device integration, the FDA issued the first “non-adjunctive” label in 2016. In June 2019, an updated Eversense CGM system received a non-adjunctive label from the FDA and can now be used as a replacement to fingerstick glucose testing for treatment decisions. This non-adjunctive indication also enabled our pathway to access patients on Medicare.

In November 2019, the Centers for Medicare and Medicaid Services, or CMS, finalized a national payment rate for Eversense that was recently published in the calendar year 2020 Physician Fee Schedule Final Rule. The Eversense CGM system became the first CGM technology to be reimbursed through the Part B Medical Services benefit for Medicare beneficiaries and expands access to our product. In December 2020, the Centers for Medicare and Medicaid Services, or CMS, released its Calendar Year 2021 Medicare Physician Fee Schedule that establishes global payment for the device cost and procedure fees for healthcare providers across the United States. This includes the establishment of national payment amounts for the three CPT© Category III codes describing the insertion (CPT 0446T), removal (0447T), and removal and insertion (0048T) of an implantable interstitial glucose sensor, which describes our Eversense CGM systems, as a medical benefit, rather than as part of the Durable Medical Equipment channel that includes other CGMs

​

We are headquartered in Germantown, Maryland. The members of our management team have held senior leadership positions at a number of medical technology and biopharmaceutical companies, including Abbott Diabetes Care, Medtronic and Johnson and Johnson. Members of our team have contributed to the development, regulatory approval and commercialization of several glucose monitoring systems and insulin pumps.

​

​

Commercial Strategy

​

We are in the process of transitioning to selling our product globally through Ascensia from selling directly to our network of distributors and strategic fulfillment partners, who provide the Eversense CGM system to healthcare providers and patients through a prescribed request and invoice insurance payors for reimbursement, as noted above in “2020 and Recent Developments”. Sales of the Eversense CGM system are widely dependent on the ability of patients to obtain coverage and adequate reimbursement from third-party payors or government agencies. Ascensia plans to leverage and target regions where we have coverage decisions for patient device use and provider insertion and removal procedure payment.

​

In the first quarter of 2020, we temporarily suspended commercial sales and marketing of the Eversense CGM System in the United States to new patients to solely focus our resources on supporting existing users. In connection with these actions, on March 26, 2020, we reduced our direct sales organization that consists of sales representatives, clinical trainers, customer care, and other specialists to educate, train, and support the patient and healthcare provider in their diabetes management with CGM systems.

​

In the third quarter of 2020, we announced the formation of a strategic partnership with Ascensia, pursuant to which Ascensia became the exclusive worldwide distribution partner for Senseonics CGM systems, including Eversense®, Eversense® XL and future generations products. In the fourth quarter of 2020, Ascensia initiated U.S. marketing and sales activities and full transition of commercial activities is expected in the second quarter of 2021, to include full marketing, market access, sales, healthcare provider training and frontline patient and provider support responsibilities. Ascensia has begun expanding its U.S. commercial organization and expects its initial U.S. staffing to be in place by the second quarter of 2021 in support of Eversense.

​

Addressing reimbursement and access barriers has been a top priority for us and during 2020 we reached over 200 million covered lives in the U.S. through positive insurance payor coverage decisions. In 2020, we continued the Eversense Bridge Program, a patient access program in the U.S. that provides financial assistance to eligible patients whose insurance coverage either does not yet cover Eversense, or in cases where Eversense is covered but the patient’s co-insurance is limiting their ability to adopt Eversense. Having played an important role in our journey to obtain broader payor policy and long-term patient retention, the Eversense Bridge Program ended on December 31, 2020.We expect Ascensia, in consultation with the company, to initiate a patient assistance program in the market once full commercial responsibility is transitioned in the near future.

​

In our overseas markets, we had entered into distribution agreements that allow third-party collaborators with direct sales forces and established distribution systems to market and promote Eversense XL primarily in the EMEA. These distribution arrangements are in the process of being replaced by our collaboration with Ascensia. Our exclusive distribution agreement for sales in Scandinavia and our exclusive distribution agreement with Roche Diabetes Care for

Table of Contents

sales in the rest of the EMEA, excluding Israel and Scandinavia, and in 17 additional countries, including Brazil, Russia, India, and China, as well as select markets in the Asia Pacific and Latin American regions expire in 2021, with the Roche agreement having expired January 31, 2021. Upon conclusion of each of these agreements, Ascensia is assuming commercialization activities in select countries where Eversense XL has already launched, beginning February 1, 2021 for Germany, Italy, Switzerland, Spain, Poland, and Netherlands. Roche will continue to support certain transition activities for approximately six months in other markets. The transition of Rubin markets is planned to occur later in 2021.

​

Our net revenues are derived from sales of the Eversense CGM system which is sold in two separate kits: the disposable Eversense Sensor Pack which includes the sensor, insertion tool, and adhesive patches, and the durable Eversense Smart Transmitter Pack which includes the transmitter and charger.

​

Distribution Agreement with Roche Diabetes Care

​

On May 24, 2016, we entered into an exclusive distribution agreement with Roche Diagnostics International AG and Roche Diabetes Care GmbH, or collectively, Roche. Pursuant to the agreement, as amended, we granted Roche the exclusive right to market, sell and distribute Eversense in the EMEA, excluding Scandinavia and Israel. In addition, Roche had exclusive distribution rights in 17 additional countries, including Brazil, Russia, India and China, as well as select markets in the Asia Pacific and Latin American regions.

​

On December 12, 2019, we amended the distribution agreement to lower minimum volumes for 2020 and increase pricing for the remaining period of the contract.

​

On November 20, 2020, we amended the distribution agreement and entered into a settlement agreement to facilitate transition to Ascensia as Roche sales concluded on January 31, 2021, including final purchases and transition support activities, and Roche’s obligation to purchase certain quantities of products at certain prices under the distribution agreement have now terminated.

​

The distribution rights under the agreement expired January 31, 2021, subject to Roche providing certain transition and wind-down services for approximately six months in markets where ADC is not initiating distribution.

​

Collaboration and Commercialization Agreement with Ascensia Diabetes Care Holdings AG

​

On August 9, 2020, we entered into a collaboration and commercialization agreement with Ascensia Diabetes Care Holdings AG pursuant to which we have granted Ascensia the exclusive right to distribute the Company’s 90-day Eversense continuous glucose monitoring system and our 180-day Eversense continuous glucose monitoring system worldwide for use in people with diabetes, with the following initial exceptions: until January 31, 2021, the territory did not include countries covered by our then existing distribution agreement with Roche Diagnostics International AG and Roche Diabetes Care GmbH, which are the Europe, Middle East and Asia, excluding Scandinavia and Israel, and 17 additional countries, including Brazil, Russia, India and China, as well as select markets in the Asia Pacific and Latin American regions; (ii) until September 13, 2021, the territory does not include countries covered by our current distribution agreement with Rubin Medical, which are Sweden, Norway and Denmark; and (iii) until May 31, 2022, the territory does not include Israel. Pursuant to the Commercialization Agreement, in the United States, Ascensia began providing sales support for the 90-day Eversense product on October 1, 2020 and the parties have been planning and making arrangements for Ascensia to ramp up sales activities and more fully assume commercial responsibilities in the second quarter of 2021. Ascensia will receive a portion of net revenue at specified tiered percentages ranging from the mid-teens to the mid-forty’s based on levels of global net revenues. Ascensia is obligated to achieve specified minimum annual revenue targets and meet specified levels of sales and marketing spend. Ascensia will purchase Eversense and Eversense XL from us at prices which have been negotiated based on parameters set forth in the commercialization agreement. We are responsible for product development and manufacturing, including regulatory submissions, approvals and registrations and second level customer support, and Ascensia is responsible for sales, marketing, market access, patient and provider onboarding and level one customer support. We have agreed to establish a joint alliance committee and joint marketing committee, each with equal representation from each party, in order to collaborate.

Clinical Development and Regulatory Pathway

​

Overview

​

The Eversense XL CGM system received a CE mark in Europe in September 2017 and is being sold commercially in our overseas markets. Our PRECISE II U.S. pivotal trial was completed during 2016. We received PMA approval from the FDA for the Eversense system in June 2018 for up to 90 days and began selling commercially in the third quarter of 2018.

​

In September 2019, we announced the enrollment completion for the PROMISE pivotal trial to evaluate the safety and accuracy of Eversense for a period of up to 180 days in the United States. In September 2020, we filed with the FDA a Premarket Approval, or PMA, supplement application to extend the wearable life of the Eversense CGM System to up to 180 days. We are also continuing to conduct a number of post-approval and feasibility studies.

​

United States Pivotal Trials

​

PRECISE II Trial

​

In 2016, we conducted our U.S. 90-day pivotal trial. The trial was a prospective, single-arm, multi-center trial designed to determine the accuracy and safety of the Eversense system. Ninety subjects were enrolled in eight centers across the United States. Eighty-seven of the ninety enrollees completed the 90-day trial.

​

The clinical trial population consisted of subjects at least 18 years of age who had a clinically confirmed diagnosis of diabetes. Subjects who had a history of severe hypoglycemia, defined as hypoglycemia resulting in loss of consciousness or seizure, or diabetic ketoacidosis, in the six months prior to the trial, were excluded from participation in the clinical trial. Accuracy measurements were taken at 1 day, 30 days, 60 days, and 90 days post-insertion. These sensor measurements were continued through the earlier of the failure of the sensor or 90 days post-insertion.

​

The purpose of this clinical trial was to evaluate the accuracy of Eversense measurements, measured by the Mean Absolute Relative Difference, or MARD, when compared with bed-side blood glucose measurements obtained using the YSI glucose analyzer over successive periods of 30 days through 90 days, as well as to assess the safety of Eversense. YSI in vitro analyzers are bed-side instruments used in hospitals and clinics to accurately measure blood glucose levels and are commonly used as comparators of glucose monitoring systems in clinical trials. MARD is a statistical calculation that measures the average absolute value of the differences, expressed as a percentage, between glucose measurements taken from interstitial fluid based on our CGM system and blood glucose measurements from YSI. The lower the MARD of a glucose monitoring system, the more accurate the system and, therefore, the more reliable the system's readings.

​

During the trial, 75 subjects underwent unilateral sensor insertions and 15 subjects underwent bilateral sensor insertions in the clinic and used Eversense’s smart transmitter and mobile app at home for the next 90 days. Subjects were blinded to the real-time glucose readings and trends during home-use and sensor readings were not used to adjust their treatment. Clinic visits were scheduled at approximately 30-day intervals in order to obtain lab reference glucose values for comparison with the sensor values and to evaluate hyperglycemic and hypoglycemic challenges in a controlled setting.

​

In the trial, we observed a MARD of 8.8% for Eversense across the 40-400 mg/dL range when compared to YSI blood reference values during the 90-day continuous wear period. We conducted a second study, the PRECISION study, to collect supplementary data early in sensor life with two additional in-clinic visits in the first 30 days after insertion. Study participants were able to see their real-time glucose readings during this study. The accuracy and safety observed in PRECISE II was confirmed in this study. In addition, the data from PRECISE II study was also analyzed using an updated glucose calculation algorithm which improved the MARD to 8.5%. Based on the data from both of these trials, we submitted a PMA application to the FDA to market Eversense in the United States for 90-day use. On June 21, 2018, we received PMA approval from the FDA for the Eversense system. We are distributing the Eversense system directly in

10

Table of Contents

the United States through our own direct sales and marketing organization. We have received Category III CPT codes for the insertion and removal of the Eversense sensor.

​

PROMISE Trial

​

In December 2018, we began enrollment for the U.S. 180-day pivotal trial. The trial is a prospective, single-arm, multi-center trial designed to evaluate the accuracy and safety of the Eversense system up to 180 days using the methods described above for the 90-day system. Over 180 subjects were enrolled in eight centers across the United States. We completed enrollment in September 2019 and had our last patient complete their 180-day visit during the first quarter of 2020.

​

The clinical trial population consists of subjects at least 18 years of age who have had a clinically confirmed diagnosis of diabetes for at least one year. Subjects with a history of unexplained severe hypoglycemia, defined as hypoglycemia resulting in loss of consciousness or seizure, or diabetic ketoacidosis, in the six months prior to the trial were excluded from participation in the clinical trial. After screening, sensor(s) were inserted and accuracy measurements were taken at multiple visits during the first 30 days and then every 30 days to 180 days post-insertion or until sensor failure, if earlier than 180 days post-insertion. In the trial, we observed performance matching that of the current Eversense 90-day product available in the United States, with a mean absolute relative difference, or MARD, of 8.5%-9.6%. This result was achieved with reduced calibration, down to one per day, while also doubling the sensor life to 180 days. Following the results of the PROMISE trial, on September 30, a Premarket Approval Application Supplement, or PMA supplement to extend the wearable life of the Eversense CGM System to 180 days was submitted to the FDA. If approved by the FDA, this new product would double sensor duration of Eversense in the United States, reducing by half the number of insertion and removal procedures required, and would provide more than 12 times longer sensor duration than other CGM systems available in the United States.

​

On February 26, 2020, we announced that the FDA approved a subgroup of PROMISE trial participants to continue for a total of 365 days to gather feasibility data on the safety and accuracy of a 365-day sensor. This sub-set of 30 participants who all had sensors with the modified chemistry were left undisturbed for 365 days with the goal of measuring accuracy and longevity over the full 365 days. Following information gathered from this sub-set and continued development efforts, and pending developments at the FDA relating to the ongoing the ongoing COVID-19 pandemic, in the second half of 2021 we plan to seek Investigational Device Exemption, or IDE, from the FDA. If the IDE is approved in a timely manner, we would target to begin enrollment of a clinical trial, in which we also intend to include a pediatric population, in the first half of 2022.

​

In April 2020, we announced that we received regulatory approval in Europe such that the Eversense XL is no longer contraindicated for MRI, which means the sensor does not need to be removed from under the skin during MRI scanning. We had previously obtained this indication for Eversense in the United States in 2019. This MRI approval is a first for the CGM category as all other sensors are required to be removed during an MRI scan.

Our Technology

​

Eversense consists of three primary components: a small sensor inserted subcutaneously under the skin by a healthcare provider; an external removable smart transmitter that receives, assesses and relays data from the sensor and provides vibratory alerts; and a mobile app that receives data from the transmitter and provides real-time glucose readings, alerts and other data on the person's mobile device. All of these components work together to provide sensor glucose values, trends and alerts to a user's mobile device within 20 milliseconds. We have designed this reliable, long-term and implantable CGM system to continually and accurately measure a person's glucose levels for up to 180 days. Eversense requires twice daily fingerstick calibrations. In June 2019, we received FDA approval for the non-adjunctive indication for the Eversense system. With this approval, the Eversense system can be used as a therapeutic CGM to replace fingerstick blood glucose measurement for dosing decisions and was launched in December 2019.

​

We believe our implantable CGM system offers the following advantages to support the management of diabetes:

​

​

​

Sensor

​

The sensor is approved to be inserted under the skin, in the upper arm, and measures the glucose in the interstitial fluid. These glucose levels are then communicated wirelessly to the smart transmitter. We have designed the sensor to last up to 180 days, as compared to other currently available CGM sensors labeled for use for between seven and 14 days.

​

The sensor consists of an optical system, known as a micro-fluorometer, encased in a rigid, translucent polymer capsule, which is 3.3 mm in diameter and 15 mm in length. The capsule is coated with a glucose-indicating hydrogel that is bound to the surface of the capsule through polymerization. This hydrogel is energized, or excited, by a light-emitting

12

Table of Contents

diode, or LED, contained in the optical system of the sensor, causing the hydrogel to fluoresce, or glow. Two photodiodes within the optical system of the sensor measure the degree of fluorescence of the hydrogel, which is proportional to the level of glucose present in the interstitial fluid. The sensor then communicates the amount of fluorescence via a near field communication, or NFC, interface to the transmitter. NFC is a high frequency wireless communication technology that enables the exchange of data and energy between devices over a short range. The sensor does not have a power source and remains electrically dormant (powered off) between readings every five minutes, and it is remotely and discretely powered, as needed, by an inductive NFC link between the sensor and the transmitter. On power-up, the LED source is energized for approximately five milliseconds to excite the hydrogel.

​

Smart Transmitter

​

The removable smart transmitter is a rechargeable, external device that is worn over the sensor implantation site using a daily adhesive patch. The transmitter supplies wireless power to the sensor through an inductive NFC link, which activates a measurement sequence every five minutes. The transmitter then receives data from the sensor and calculates glucose concentrations and trends. Based on these calculations and on the user's individual settings for glucose levels, the transmitter determines if an alert condition exists, in which case the transmitter communicates the condition to the user through the mobile app and through on-body vibration. The information from the transmitter is also transmitted for display to the user's mobile device via Bluetooth Low-Energy, or BLE. Our transmitter is functional for at least 24 hours following a full charge and can be fully charged in fifteen minutes.

​

Mobile App

​

Our mobile app is a software application that runs on both platforms; iOS mobile devices, including iPhones, iPads and Apple Watches, and Android mobile devices. The mobile app receives information from the transmitter via BLE and displays that information discreetly to the user. This user-friendly, intuitive app provides real-time glucose readings, alerts, trends, and graphs. Within the mobile app, users can set alerts based on, among other things, glucose levels. The mobile app also allows for cloud-based storage.

​

​

Future Product Development

​

We intend to continue to expand our line of product offerings to benefit people with diabetes and healthcare providers. We expect these product development initiatives to include system modifications and next generation enhancements that we believe will further increase the convenience and appeal of our products to the diabetes community.

​

We are focusing our future development efforts on enhancing current product offerings by reducing the twice daily calibrations to once a day calibration, and further progressing to once per week calibration. Our next generation sensor under feasibility testing now is designed to extend the sensor duration even longer at up to 365 days. We expect the next generation sensor to support our goal of extending the market for long-term implantable CGM to include Type 2 patients not on intensive insulin therapy. We are also developing our “Freedom” product variation to allow for a 2-in-1 glucose monitoring system combining the functionality of CGM and Flash Glucose Monitoring, or FGM, in an implantable sensor that may be utilized with a smart transmitter to get continuous glucose readings and alerts, or be utilized through a swipe over the sensor with a smart phone to get on-demand glucose reading without a smart transmitter. We are seeking to ensure that we meet the growing and unique needs of people with diabetes utilizing our core and proprietary sensor technology. The company’s technology also has potential applications measuring analytes other than glucose, such as oxygen, and the company may consider opportunities for the development or out-licensing of such applications.

​

​

Sales and Marketing

​

We are in the early commercialization stages of Eversense and are focused on driving awareness and adoption of our CGM system amongst intensively managed patients and their healthcare providers. Building strong adoption with

13

Table of Contents

an implantable device requires a strong network of healthcare providers trained on the Eversense sensor placement procedure. In the first few quarters of our commercial launch, our focus was ensuring the Endocrinology providers obtained the necessary training needed to support their diabetes patients. In 2019, we began our second phase of establishing a large network of Eversense proceduralists with the launch of the Certified Eversense Specialist, or CES, network. This group of healthcare providers includes specialists who have strong familiarity with conducting in-office procedures such as dermatologists and plastic surgeons. The CES network offers an alternative for healthcare providers who want to prescribe Eversense for their patients but prefer to refer the procedure to a specialist.

​

As people with diabetes often consult with their healthcare providers about treatment options, we believe that educating healthcare providers regarding the benefits of Eversense compared to SMBG and other currently available CGM systems is an important step in promoting its use in people with diabetes. Our European experience and our feedback in the United States indicates healthcare providers highly value the accuracy and sensor duration of our CGM system and the majority of physicians surveyed considered the insertion process to be fairly simple or feasible. We intend to continue educating healthcare providers and people with diabetes on the advantages of Eversense compared to SMBG and other currently available CGM systems.

​

As a result of our strategic partnership, Ascensia will be responsible for sales, marketing, market access, patient and provider onboarding and level one customer support. We have established a joint alliance committee and joint marketing committee, each with equal representation from each party, in order to collaborate.

​

​

Reimbursement

​

Coverage in the United States

​

In the U.S. market, it is essential to obtain third-party payor coverage policies, coding mechanisms, and adequate payment for medical technology to expand market acceptance and adoption. CGM as a class of products has been broadly accepted by commercial third-party payors, such as health insurers and health maintenance organizations, and more recently by Medicare for patients who require the use of insulin to manage their diabetes. We approach the U.S. commercial third-party payor community in efforts to establish coverage for Eversense. To date, approximately 200 million people in the United States may have coverage and access to the Eversense via commercial or government (i.e., Medicare) payors.

​

Some commercial payors have denied coverage deeming Eversense as an “experimental and investigational” technology electing to wait for further clinical evidence, more safety data, or time in market. We disagree with this position as the CGM class has already proven to improve health outcomes and Eversense is another product that fits into the class. Additionally, in 2019 we published several sets of real-world data, which show Eversense provides the same clinical benefits as other CGM systems and has a favorable safety profile. However, until payment for the Eversense sensor placement becomes consistent, some patients will be required to bear the financial cost for the placement of the sensor by their healthcare provider. As a result, some patients and their healthcare provider may choose not to use Eversense on a widespread basis. Our patient access programs and patient appeals support, including the Eversense Bridge Program, which was discontinued on December 31, 2020, have been key initiatives to expanding payor policy and acceptance through case by case review and eventual denial overturn and we anticipate Ascensia initiating select programs for this purpose. This can be a long process with varying results in each case but is a prudent step to challenge payor positions of non-coverage given the strong evidence that supports CGM and Eversense.

​

Coverage Outside the United States

​

In countries outside the United States, coverage for CGM systems is obtained from various sources, including governmental authorities, national healthcare systems, private health insurance plans, and hospital funds. Coverage systems in international markets vary significantly by country and, within some countries, by region. Coverage approvals must be obtained on a country-by-country, region-by-region or, in some instances, a case-by case basis. The responsibility for securing this coverage resides with our third-party distributors in the respective markets.

​

Manufacturing and Quality Assurance

​

We currently outsource the manufacturing of all components of the Eversense system to contract manufacturers across North America and Europe. We plan to continue with an outsourced manufacturing arrangement for the foreseeable future. Our contract manufacturers are all recognized in their field for their competency to manufacture the respective portions of our system and have quality systems established that meet FDA and, to the extent required, international regulatory requirements. We believe the manufacturers we currently utilize have sufficient capacity to meet our requirements. We believe that, as we increase our demand in the future, our per unit costs will decrease materially.

​

We have received certification from BSI, our Notified Body to the International Standards Organization, or ISO, for our quality system. This ISO 13485:2016 certification includes design control requirements. As a medical device manufacturer, the facilities of our sterilization and other critical suppliers are subject to periodic inspection by the FDA and corresponding state and foreign agencies. We believe that our quality systems and those of our suppliers are robust and achieve high product quality.

​

Typically, our outside vendors produce the components to our specifications and in many instances to our designs. Our suppliers are audited periodically by our quality department to ensure conformity with the specifications, policies and procedures for our devices. We believe that, if necessary, alternative sources of supply would be available in a relatively short period of time and on commercially reasonable terms. Most of the raw materials we use in our manufacturing operations are available from more than one source. However, we obtain certain raw materials principally from only one source. In the event one of these suppliers was unable to provide the materials or product, we generally seek to maintain sufficient inventory to supply the market until an alternative source of supply can be implemented. However, in the event of an extended failure of a supplier, it is possible that we could experience an interruption in supply until we established new sources or, in some cases, implemented alternative processes.

​

​

Competition

​

The market for CGM systems is developing and competitive, subject to rapid change and significantly affected by new product introductions. We compete with well-capitalized companies, some of which are publicly traded, that manufacture CGM systems including Dexcom, Medtronic and Abbott. Each of these companies has received approval from the FDA to market their respective CGM system. Dexcom’s CGM system was the first CGM system to be approved by the FDA for marketing as a non-adjunctive device, and Abbott’s Freestyle Libre was also approved for non-adjunctive use. Both Dexcom (G6) and Abbott (Freestyle Libre) systems have factory calibration, and do not require user calibration.

​

Dexcom has also received the first FDA iCGM indication allowing its Dexcom G6 to be interoperable with other diabetes tech devices such as insulin pumps. As the industry evolves, we anticipate encountering increasing competition from companies that integrate CGM with insulin pumps. Abbott also received an iCGM indication for their Freestyle Libre 2 product and we expect all other CGM companies besides Dexcom to pursue an iCGM indication including Medtronic.

​

In addition to CGM providers, we also compete with providers of SMBG systems. Three companies currently account for a substantial share of the worldwide sales of SMBG systems: Roche Diabetes Care, a division of Roche Diagnostics; Abbott; and Ascensia Diabetes Care Holdings AG.

​

We may also compete with companies who are developing real-time intermittent sensing devices, low cost transcutaneous CGM systems, fully implantable CGM devices and non-invasive CGM system to measure a user's glucose level. There are also a number of academic and other institutions involved in various phases of our industry's technology development.

​

15

Table of Contents

Although we face potential competition from many different sources, we believe that our technology, knowledge, experience and scientific resources provide us with competitive advantages. The key competitive factors affecting the success of Eversense are accuracy, duration, convenience, alert functionality, and customer support.

​

Many of the companies which we compete with have significantly greater financial resources and expertise in research and development, manufacturing, preclinical testing, conducting clinical trials, obtaining regulatory approvals and marketing approved products than we do. Mergers and acquisitions in the pharmaceutical, biotechnology and diagnostic industries may result in even more resources being concentrated among a smaller number of our competitors. Smaller or earlier stage companies may also prove to be significant competitors, particularly through collaborative arrangements with large and established companies. These competitors also compete with us in recruiting and retaining qualified scientific and management personnel and establishing clinical trial sites and subject registration for clinical trials, as well as in acquiring technologies complementary to, or necessary for, our development.

​

​

Intellectual Property

​

Protection of our intellectual property is a strategic priority for our business. We rely on a combination of patents, trademarks, copyrights, trade secrets as well as nondisclosure and assignment of invention agreements, material transfer agreements, confidentiality agreements and other measures to protect our intellectual property and other proprietary rights.

​

Patents

​

As of December 31, 2020, we held a total of approximately 519 issued patents and pending patent applications that relate to our CGM system. Our intellectual property portfolio includes 90 issued United States patents, 254 patents issued in countries outside the United States and 175 pending patent applications worldwide. Our patents expire between 2021 and 2043, subject to any patent extensions that may be available for such patents. If patents are issued on our pending patent applications, the resulting patents are projected to expire on dates ranging from 2021 to 2043.

​

Our patents and patent applications cover certain aspects of our core sensor technologies and our product concepts for CGM systems. However, our patent applications may not result in issued patents, and any patents that have been issued or may be issued in the future may not protect the commercially important aspects of our technology. Furthermore, the validity and enforceability of our issued patents may be challenged by third parties and our patents could be invalidated or modified by the issuing governmental authority. Third parties may independently develop technology that is not covered by our patents that is similar to or competes with our technology. In addition, our intellectual property may be infringed or misappropriated by third parties, particularly in foreign countries where the laws and governmental authorities may not protect our proprietary rights as effectively as those in the United States.

​

The medical device industry in general, and the glucose testing sector of this industry in particular, are characterized by the existence of a large number of patents and frequent litigation based on assertions of patent infringement. We are aware of numerous patents issued to third parties that may relate to the technology used in our business, including the design and manufacture of CGM sensors and CGM systems, as well as methods for continuous glucose monitoring. Each of these patents contains multiple claims, any one of which may be independently asserted against us. The owners of these patents may assert that the manufacture, use, sale or offer for sale of our CGM sensors or CGM systems infringes one or more claims of their patents. Furthermore, there may be additional patents issued to third parties of which we are presently unaware that may relate to aspects of our technology that such third parties could assert against us and materially and adversely affect our business. In addition, because patent applications can take many years to issue, there may be patent applications that are currently pending and unknown to us, which may later result in issued patents that third parties could assert against us and materially and adversely affect our business.

​

Any adverse determination in litigations, post grant trial proceedings, including interference proceedings, at the Patent Office relating to intellectual property to which we are or may become a party could subject us to significant liabilities to third parties or require us to seek licenses from third parties, and result in the cancellation and/or invalidation of our intellectual property. Furthermore, if a court finds that we have willfully infringed a third party's

16

Table of Contents

intellectual property, we could be required to pay treble damages and/or attorney fees for the prevailing party, in addition to other penalties. Although intellectual property disputes in the medical device area are often settled through licensing or similar arrangements, costs associated with such arrangements can be substantial and often require ongoing royalty payments. 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 products to avoid infringement; if we are able to redesign our products to avoid infringement, we may not receive FDA approval in a timely manner. Adverse determinations in a judicial or administrative proceeding or failure to obtain necessary licenses could prevent us from manufacturing and selling our products, which could have a significant adverse impact on our business.

​

Trademarks

​

We have no pending U.S. trademark applications and 20 pending foreign trademark applications, as well as 14 U.S. trademark registrations and 116 foreign trademark registrations.

​

Trade Secrets

​

We also rely on trade secrets, technical know-how and continuing innovation to develop and maintain our competitive position. We seek to protect such intellectual property and proprietary information by generally requiring our employees, consultants, contractors, scientific collaborators and other advisors to execute non-disclosure and assignment of invention agreements upon the commencement of their employment or engagement as the case may be. Our agreements with our employees prohibit them from providing us with any intellectual property or proprietary information of third parties. We also generally require confidentiality agreements or material transfer agreements with third parties that receive or have access to our confidential information, data or other materials. Notwithstanding the foregoing, there can be no assurance that our employees and third parties that have access to our confidential proprietary information will abide by the terms of their agreements. Despite the measures that we take to protect our intellectual property and confidential information, unauthorized third parties may copy aspects of our products or obtain and use our proprietary information.

​

​

Government Regulation

​

The Eversense system is a medical device subject to extensive and ongoing regulation by the FDA, CMS, the European Commission, and regulatory bodies in other countries. Regulations cover virtually every critical aspect of a medical device company's business operation, including research activities, product development, contracting, reimbursement, medical communications, and sales and marketing. In the United States, the Federal Food, Drug and Cosmetic Act, or FDCA, and the implementing regulations of the FDA govern product design and development, preclinical and clinical testing, premarket clearance or approval, product manufacturing, import and export, product labeling, product storage, recalls and field safety corrective actions, advertising and promotion, product sales and distribution, and post-market clinical surveillance. Our business is subject to federal, state, local, and foreign regulations, such as ISO 13485, ISO 14971, FDA's Quality System Regulation, or QSR, contained in 21 CFR Part 820, and Directive 90/385/EEC concerning active implantable medical devices, as amended.

​

Regulation by the FDA

​

The FDA classifies medical devices into one of three classes according to the degree of risk the FDA determines to be associated with a device and the level of regulatory control deemed necessary to ensure the device’s safety and effectiveness. The Eversense System is a Class III device and subject to pre-market approval application under section 515 of the FDCA in order to obtain a marketing approval. A PMA application must be supported by valid scientific evidence that typically includes extensive technical, preclinical, clinical, manufacturing and labeling data, to demonstrate to the FDA's satisfaction the safety and efficacy of the device. A PMA application also must include a complete description of the device and its components, a detailed description of the methods, facilities and controls used to manufacture the device, and proposed labeling. After a PMA application is submitted and found to be sufficiently complete, the FDA begins an in-depth review of the submitted information.

​

17

Table of Contents

New PMA applications or PMA supplements may be required for modifications to the manufacturing process, labeling, device specifications, materials or design of a device that has been approved through the PMA process. PMA supplements often require submission of the same type of information as an initial PMA application, except that the supplement is limited to information needed to support any changes from the device covered by the approved PMA application and may or may not require as extensive technical or clinical data or the convening of an advisory panel.

​

Any devices we manufacture and distribute pursuant to clearance or approval by the FDA are subject to pervasive and continuing regulation by the FDA and certain state agencies. These include product listing and establishment registration requirements, which help facilitate FDA inspections and other regulatory actions. As a medical device manufacturer, all of our manufacturing facilities are subject to inspection on a routine basis by the FDA. We are required to adhere to applicable regulations setting forth detailed cGMP requirements, as set forth in the QSR, which require, manufacturers, including third-party manufacturers, to follow stringent design, testing, control, documentation and other quality assurance procedures during all phases of the design and manufacturing process. Noncompliance with these standards can result in, among other things, fines, injunctions, civil penalties, recalls or seizures of products, total or partial suspension of production, refusal of the government to grant 510(k) clearance or PMA approval of devices, withdrawal of marketing approvals and criminal prosecutions. We believe that our design, manufacturing and quality control procedures are in compliance with the FDA’s regulatory requirements.

​

We must also comply with post-market surveillance regulations, including medical device reporting, or MDR, requirements which require that we review and report to the FDA any incident in which our products may have caused or contributed to a death or serious injury. We must also report any incident in which our product has malfunctioned if that malfunction would likely cause or contribute to a death or serious injury if it were to recur.

​

Labeling and promotional activities are subject to scrutiny by the FDA and, in certain circumstances, by the Federal Trade Commission. Medical devices approved or cleared by the FDA may not be promoted for unapproved or uncleared uses, otherwise known as “off-label” promotion. The FDA and other agencies actively enforce the laws and regulations prohibiting the promotion of off-label uses, and a company that is found to have improperly promoted off-label uses may be subject to significant liability, including substantial monetary penalties and criminal prosecution.

​

International Regulation

​

International sales of medical devices are subject to local government regulations, which may vary substantially from country to country. The time required to obtain approval in another country may be longer or shorter than that required for FDA approval, and the requirements may differ. There is a trend towards harmonization of quality system standards among the European Union, United States, Canada and various other industrialized countries.

​

The European Union, or EU, has adopted numerous directives and standards regulating the design, manufacture, clinical trials, labeling and adverse event reporting for medical devices. Other countries, such as Switzerland, have voluntarily adopted laws and regulations that mirror those of the EU with respect to medical devices. Devices that comply with the requirements of a relevant directive will be entitled to bear the CE conformity marking, indicating that the device conforms to the essential requirements of the applicable directives, or Essential Requirements, and, accordingly, can be commercially distributed throughout the EU. To assist manufacturers in satisfying the Essential Requirements, the European standards organizations have prepared European standards applicable to medical devices. These include harmonized international quality standards aimed at ensuring that medical devices are correctly designed and manufactured. The method of assessing conformity varies depending on the class of the product, but normally involves a combination of self-assessment by the manufacturer and a third-party assessment by a "Notified Body." Notified Bodies are entities licensed (‘notified’) by the individual European member states to provide independent certification of certain classes of medical device. They apply for and are designated to carry out this function by the relevant national competent authorities, which carry out periodic assessment audits to determine whether the Notified Bodies continue to satisfy the necessary requirements. A conformity assessment conducted by a Notified Body may consist of an audit of the medical device manufacturer's quality system and specific testing of the manufacturer's product to ensure that the medical device complies with the Essential Requirements. Once the appropriate conformity assessment procedure has been completed, the manufacturer must draw up a written declaration of conformity and affix the CE mark to the device. The device can then be marketed throughout the European Economic Area (being the EU, Norway, Iceland

18

Table of Contents

and Liechtenstein) or EEA. Notified Bodies perform surveillance and unannounced audits at the manufacturer and critical suppliers with respect to the devices covered by the certificates issued by them. If non-conformities raised during the audits are not timely remedied by the manufacturer, the Notified Body may (partially or wholly) suspend or withdraw the certificate concerned. Additional local requirements may apply on a country-by-country basis. Outside of the European Union, regulatory approval would need to be sought on a country-by-country basis in order for us to market our products.

​

All manufacturers placing medical devices into the market in the EEA must comply with the EU Medical Device Vigilance System. Under this system, incidents must be reported to the relevant authorities of the Member States of the EEA, and manufacturers are required to take Field Safety Corrective Actions, or FSCAs, to reduce a risk of death or serious deterioration in the state of health associated with the use of a medical device that is already placed on the market. An incident is defined as any malfunction or deterioration in the characteristics and/or performance of a device, as well as any inadequacy in the labeling or the instructions for use which, directly or indirectly, might lead to or might have led to the death of a patient or user or of other persons or to a serious deterioration in their state of health. An FSCA may include the recall, modification, exchange, destruction or retrofitting of the device. FSCAs must be communicated by the manufacturer or its legal representative to its customers and/or to the end users of the device through Field Safety Notices.

​

In May 2017, the European Commission finalized and adopted the text of the Medical Device Regulation (EU) 2017/745, or the EU Medical Device Regulation, which will repeal and replace both Directive 93/42/EEC concerning medical devices and Directive 90/385/EEC concerning active implantable medical devices. The majority of the provisions in the EU Medical Device Regulation were to apply from Spring 2020, however, the enforcement has been postponed by a year due to the COVID-19 pandemic. The current CE certificate will continue to be in effect, while the Company works to ensure compliance with the EU Medical Device Regulation and transitions the CE certificate from current 90/385/EEC Directive to MDR.

​

Other Regulatory Requirements

​

Even after a device receives clearance or approval and is placed in commercial distribution, numerous regulatory requirements apply. These include:

​

​

Also, the FDA requires us to conduct Post Approval Studies (post-market surveillance studies) and establish and maintain a system for tracking our products through the chain of distribution to the patient level. The FDA and applicable regulatory agencies enforce regulatory requirements by conducting periodic, unannounced inspections and market surveillance. Inspections may include the manufacturing facilities of our subcontractors.

​

Moreover, the FDA strictly regulates marketing, labeling, advertising and promotion of medical products. Medical products may be promoted only for the approved indications and in accordance with the provisions of the approved label, although physicians, in the practice of medicine, may prescribe approved medical products for unapproved indications. Companies may also share truthful and not misleading information that is otherwise consistent with the labeling. The FDA and other agencies actively enforce the laws and regulations prohibiting the promotion of

19

Table of Contents

off-label uses, and a company that is found to have improperly promoted off-label uses may be subject to significant liability.

​

In the United States, failure to comply with applicable regulatory requirements can result in enforcement actions by the FDA and other regulatory agencies. These may include any of the following sanctions or consequences:

​

​

In the European Union, member states are responsible for enforcing the EU’s medical device rules and for ensuring that only compliant medical devices are placed on the market or put into service in their jurisdictions. They have powers to suspend the marketing and use, or demand the recall, of unsafe or non-compliant devices. They also have the power to bring enforcement action against companies or individuals for breaches of the device rules. Non-compliance may also result in Notified Bodies revoking any certificate of conformity that they have issued for a device or the manufacturer’s quality system.

​

Our contract manufacturers, specification developers and some suppliers of components or device accessories, also are required to manufacture our products in compliance with current good manufacturing practice requirements set forth in the QSR. The QSR requires a quality system for the design, manufacture, packaging, labeling, storage, installation and servicing of marketed devices, and it includes extensive requirements with respect to quality management and organization, device design, buildings, equipment, purchase and handling of components or services, production and process controls, packaging and labeling controls, device evaluation, distribution, installation, complaint handling, servicing, and record keeping. The FDA evaluates compliance with the QSR through periodic unannounced inspections that may include the manufacturing facilities of our subcontractors. If the FDA believes that any of our contract manufacturers or regulated suppliers are not in compliance with these requirements, it can shut down such manufacturing operations, require recall of our products, refuse to approve new marketing applications, institute legal proceedings to detain or seize products, enjoin future violations or assess civil and criminal penalties against us or our officers or other employees.

​

Health Insurance Portability and Accountability Act of 1996 and Similar Foreign and State Laws and Regulations Affecting the Transmission, Security and Privacy of Health Information

​

We may also be subject to data privacy and security regulation by both the federal government and the states in which we conduct our business. The Health Insurance Portability and Accountability Act of 1996, or HIPAA, as amended by the Health Information Technology for Economic and Clinical Health Act, or HITECH, and their respective implementing regulations, imposes specified requirements relating to the privacy, security and transmission of individually identifiable health information. Among other things, HITECH makes HIPAA's security standards directly applicable to business associates, defined as service providers of covered entities, which include certain healthcare providers, health plans and healthcare clearinghouses, that create, receive, maintain or transmit protected health information in connection with providing a service for or on behalf of a covered entity, and their covered subcontractors. HITECH also created four new tiers of civil monetary penalties and gave state attorneys general new authority to file civil actions for damages or injunctions in federal courts to enforce the federal HIPAA laws and seek attorneys' fees and costs associated with pursuing federal civil actions. Accordingly, state attorneys general (along with private plaintiffs) have brought civil actions seeking injunctions and damages resulting from alleged violations of HIPAA’s privacy and

20

Table of Contents

security rules. In addition, many state laws govern the privacy and security of health information in certain circumstances, many of which differ from HIPAA and each other in significant ways and may not have the same effect.

​

On April 5, 2017, the European Parliament passed the Medical Devices Regulation, which repeals and replaces the EU Medical Devices Directive. Unlike directives, which must be implemented into the national laws of the EEA member States, the regulations would be directly applicable (i.e., without the need for adoption of EEA member State laws implementing them) in all EEA member States and are intended to eliminate current differences in the regulation of medical devices among EEA member States. The Medical Devices Regulation, among other things, is intended to establish a uniform, transparent, predictable and sustainable regulatory framework across the EEA for medical devices and in vitro diagnostic devices and ensure a high level of safety and health while supporting innovation.

​

The Medical Devices Regulation will however only become applicable three years after publication in May 2020. Once applicable, the new regulations will among other things:

​

​

These modifications may have an impact on the way we design and manufacture products and the way we conduct our business in the EEA.

​

In the European Union (and, specifically the European Economic Area) (EU/EEA), the General Data Protection Regulation (2016/679), or GDPR, went into effect on May 25, 2018 and replaced Directive 95/46/EC (the EU Privacy Directive). The GDPR applies to personal data about identified or identifiable data subjects processed by automated means and data contained in, or intended to be part of, non-automated filing systems (traditional paper files) as well as transfer of such data to a country outside of the EU/EEA. Under the GDPR, fines of up to €20.0 million or up to 4% of the annual global turnover of the infringer, whichever is greater, could be imposed for certain categories of infractions that constitute significant non-compliance. The GDPR includes more stringent operational requirements for data processors and data controllers and creates additional rights for data subjects. Additionally, in January 2020, the United Kingdom withdrew from the European Union, commonly referred to as “Brexit”. The implications of Brexit and the future trading relationship between the United Kingdom and the EU are still uncertain and could lead to further legislative and regulatory changes. In March 2017, the United Kingdom began the process to leave the EU by April 2019. While the Data Protection Act of 2018, that “implements” and complements the GDPR has achieved Royal Assent on May 23, 2018 is now effective in the United Kingdom, it is still unclear whether transfer of data from the EEA to the United Kingdom will remain lawful under GDPR. We may incur liabilities, expenses, costs, and other operational losses under GDPR and applicable EU Member States and the United Kingdom privacy laws in connection with any measures we take to comply with them.

​

Additionally, California recently enacted legislation, effective January 1, 2020, that has been dubbed the first “GDPR-like” law in the United States. Known as the California Consumer Privacy Act, or CCPA, it creates new individual privacy rights for consumers (as that word is broadly defined in the law) and places increased privacy and security obligations on entities handling personal data of consumers or households. The CCPA requires covered companies to provide new disclosures to California consumers, provide such consumers new ways to opt-out of certain sales of personal information, and allows for new causes of action for data breaches. As currently written, the CCPA could impact our business activities and is an example of the type of activity in an evolving regulatory environment related to personal data and protected health information that could continue to affect our operations.

Fraud and Abuse Laws

​

In addition to FDA restrictions, there are numerous U.S. federal and state laws pertaining to healthcare fraud and abuse, including anti-kickback laws and physician self-referral laws. Our relationships with healthcare providers and other third parties are subject to scrutiny under these laws. Violations of these laws are punishable by significant criminal, civil, and administrative sanctions, including, in some instances, imprisonment and exclusion from participation in federal and state healthcare programs, including the Medicare, Medicaid and Veterans Administration health programs.

​

Federal Anti-Kickback and Self-Referral Laws

​

The federal Anti-Kickback Statute prohibits persons from knowingly and willfully soliciting, receiving, offering or providing remuneration (including any kickback, bribe or rebate), directly or indirectly, overtly or covertly, to induce either the referral of an individual, or the furnishing, recommending, or arranging of a good or service, for which payment may be made under a federal healthcare program such as Medicare and Medicaid or other federal healthcare programs. The term "remuneration" has been broadly interpreted to include anything of value, including such items as gifts, discounts, the furnishing of supplies or equipment, credit arrangements, waiver of payments and providing anything at less than its fair market value. Although there are a number of statutory exceptions and regulatory safe harbors protecting some common activities from prosecution, the exceptions and safe harbors are drawn narrowly and require strict compliance to provide protection. Practices that involve remuneration that may be alleged to be intended to induce prescribing, purchases or recommendations may be subject to scrutiny if they do not qualify for an exception or safe harbor. Failure to meet all of the requirements of a particular applicable statutory exception or regulatory safe harbor does not make the conduct per se illegal under the federal Anti-Kickback Statute. Instead, the legality of the arrangement will be evaluated on a case-by-case basis based on a review of all its relevant facts and circumstances. Several courts have interpreted the statute's intent requirement to mean that if any one purpose of an arrangement involving remuneration is to induce referrals of (or purchases, or recommendations related to) federal healthcare covered business, the federal Anti-Kickback Statute has been implicated and potentially violated.

​

The penalties for violating the federal Anti-Kickback Statute include imprisonment for up to ten years, criminal fines of up to $100,000 per violation, possible exclusion from federal healthcare programs such as Medicare and Medicaid and other penalties, including significant civil monetary penalties and integrity oversight and reporting obligations to resolve allegations of non-compliance. Many states have adopted prohibitions similar to the federal Anti-Kickback Statute, some of which do not have the same exceptions or safe harbors and apply to the referral of patients for healthcare services reimbursed by any source, not only by the Medicare and Medicaid programs. Further, the federal Anti-Kickback Statute was amended by the Patient Protection and Affordable Care Act, as amended by the Health Care and Education Reconciliation Act, or, collectively, PPACA. Specifically, as noted above, under the federal Anti-Kickback Statute, the government must prove the defendant acted "knowingly" to prove a violation occurred. The PPACA added a provision to clarify that with respect to violations of the federal Anti-Kickback Statute, "a person need not have actual knowledge" of the statute or specific intent to commit a violation of the statute. This change effectively overturns case law interpretations that set a higher standard under which prosecutors had to prove the specific intent to violate the law. In addition, the PPACA codified case law 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 federal civil False Claims Act.

​

Federal law also includes a provision commonly known as the "Stark Law," which prohibits a physician from referring Medicare or Medicaid patients to an entity providing "designated health services," including a company that furnishes durable medical equipment, in which the physician has an ownership or investment interest or with which the physician has entered into a compensation arrangement. Violation of the Stark Law could result in denial of payment, disgorgement of reimbursements received under a noncompliant arrangement, civil penalties, and exclusion from Medicare, Medicaid or other governmental programs. We believe that we have structured our provider arrangements to comply with current fraud and abuse law requirements.

​

Nevertheless, a determination of liability under such laws could result in fines and penalties and restrictions on our ability to operate in these jurisdictions.

Table of Contents

​

Additionally, as some of these laws are still evolving, we lack definitive guidance as to the application of certain key aspects of these laws as they relate to our arrangements with providers with respect to patient training. As a result, our provider and training arrangements may ultimately be found to be not in compliance with applicable federal law.

​

Federal False Claims Act & HIPAA

​

The federal False Claims Act provides, in part, that the federal government may bring a lawsuit against any person whom it believes has knowingly presented, or caused to be presented, a false or fraudulent request for payment from the federal government, or who has made a false statement or used a false record to get a claim approved. In addition, amendments in 1986 to the federal False Claims Act have made it easier for private parties to bring "qui tam" whistleblower lawsuits against companies under the federal False Claims Act. Penalties include significant civil monetary penalties for each false claim, plus three times the amount of damages that the federal government sustained because of the act of that person. Qui tam actions have increased significantly in recent years, causing greater numbers of healthcare companies to have to defend a false claim action, pay fines, be excluded from Medicare, Medicaid or other federal or state healthcare programs, or be subject to integrity oversight and reporting obligations to resolve allegations of non-compliance, as a result of an investigation arising out of such action.

​

There are other federal anti-fraud laws that that prohibit, among other actions, knowingly and willfully executing, or attempting to execute, a scheme to defraud any healthcare benefit program, including private third-party payors, knowingly and willfully embezzling or stealing from a healthcare benefit program, willfully obstructing a criminal investigation of a healthcare offense, and knowingly and willfully falsifying, concealing or covering up a material fact or making any materially false, fictitious or fraudulent statement in connection with the delivery of or payment for healthcare benefits, items or services.

​

Additionally, HIPAA established two federal crimes for healthcare fraud and false statements relating to healthcare matters. The healthcare fraud statute prohibits knowingly and willfully executing a scheme to defraud any healthcare benefit program, including private payors. The false statements statute prohibits knowingly and willfully falsifying, concealing or covering up a material fact or making any materially false, fictitious or fraudulent statement in connection with the delivery of or payment for healthcare benefits, items or services. A violation of either of these statutes is a felony and may result in fines, imprisonment, exclusion from Medicare, Medicaid or other federal or state healthcare programs, or integrity oversight and reporting obligations to resolve allegations of non-compliance.

​

Civil Monetary Penalties Law

​

In addition to the federal Anti-Kickback Statute and the civil and criminal false claims laws, including the federal False Claims Act, the federal government has the authority to seek civil monetary penalties, or CMPs, assessments, and exclusion against an individual or entity based on a wide variety of prohibited conduct. For example, the Civil Monetary Penalties Law authorizes the imposition of substantial CMPs against an entity that engages in activities including, but not limited to: (1) knowingly presenting or causing to be presented, a claim for services not provided as claimed or which is otherwise false or fraudulent in any way; (2) knowingly giving or causing to be given false or misleading information reasonably expected to influence the decision to discharge a patient; (3) offering or giving remuneration to any beneficiary of a federal health care program likely to influence the receipt of reimbursable items or services; (4) arranging for reimbursable services with an entity which is excluded from participation from a federal health care program; (5) knowingly or willfully soliciting or receiving remuneration for a referral of a federal health care program beneficiary; or (6) using a payment intended for a federal health care program beneficiary for another use. Noncompliance can result in significant civil money penalties for each wrongful act, assessment of three times the amount claimed for each item or service and exclusion from the federal healthcare programs.

​

State Fraud and Abuse Provisions

​

Many states have also adopted some form of anti-kickback and anti-referral laws and a false claims act, some of which apply regardless of source of payment and do not have the same exceptions as the federal laws. We believe that

23

Table of Contents

we are in conformance to such laws. Nevertheless, a determination of liability under such laws could result in fines and penalties and restrictions on our ability to operate in these jurisdictions.

​

Physician Payments Sunshine Act

​

Transparency laws regarding payments or other items of value provided to healthcare providers and teaching hospitals may also impact our business practices. The federal Physician Payment Sunshine Act requires most medical device manufacturers to report annually to CMS financial arrangements, payments, or other transfers of value made by that entity to physicians (defined to include doctors, dentists, optometrists, podiatrists, and chiropractors) and teaching hospitals. Beginning in 2022, applicable manufacturers also will be required to report information regarding payments and other transfers of value provided to physician assistants, nurse practitioners, clinical nurse specialists, certified registered nurse anesthetists, anesthesiologist assistants and certified nurse midwives during the previous year. The payment information is made publicly available in a searchable format on a CMS website. Over the next several years, we will need to dedicate significant resources to establish and maintain systems and processes in order to comply with these regulations. Failure to comply with the reporting requirements can result in significant civil monetary penalties. Similar laws have been enacted or are under consideration in many states and foreign jurisdictions.

​

Healthcare Reform

​

Federal and state governments continue to propose and pass new legislation and regulations designed to contain or reduce the cost of healthcare. Such new laws may result in decreased reimbursement for medical devices, which may further exacerbate industry-wide pressure to reduce the prices charged for medical devices. For example. in March 2010, the PPACA, was enacted, which substantially changes the way healthcare is financed by both governmental and private insurers, encourages improvements in the quality of healthcare items and services and significantly impacts the medical device industry. In the years since its enactment, there have been significant developments in, and continued legislative activity around, attempts to repeal or repeal and replace the PPACA. While Congress has not passed comprehensive repeal legislation, several bills affecting the implementation of certain taxes under the PPACA have been signed into law. The Tax Cuts and Jobs Act of 2017, or Tax Act, included a provision which repealed, effective January 1, 2019, the tax-based shared responsibility payment imposed by the PPACA on certain individuals who fail to maintain qualifying health coverage for all or part of a year that is commonly referred to as the “individual mandate”. Additionally, the 2020 federal spending package permanently eliminated, effective January 1, 2020, the PPACA-mandated medical device tax and the “Cadillac” tax on high-cost employer-sponsored health coverage and, effective January 1, 2021, also eliminated the health insurer tax. On December 14, 2018, a Texas U.S. District Court Judge ruled that the PPACA is unconstitutional in its entirety because the “individual mandate” was repealed by Congress as part of the Tax Cuts and Jobs Act of 2017. Additionally, on December 18, 2019, the U.S. Court of Appeals for the 5th Circuit upheld the District Court ruling that the individual mandate was unconstitutional and remanded the case back to the District Court to determine whether the remaining provisions of the PPACA are invalid as well. The U.S. Supreme Court is currently reviewing the case, although it is unknown when a decision will be made. Further, it is unclear how the Supreme Court ruling, other such litigation, and the healthcare reform measures of the Biden administration will impact the PPACA.

​

Brexit and the Regulatory Framework in the United Kingdom

​

On January 31, 2020, the United Kingdom, or UK, formally withdrew from the EU, commonly referred to as “Brexit”. The United Kingdom and the EU are currently in a transition period during which the United Kingdom and the EU are negotiating additional arrangements, including their future trading arrangement. In December 2020, the U.K. and E.U. agreed on a trade and cooperation agreement that will apply provisionally after the end of the transition period until it is ratified by the parties to the agreement. On December 31, 2020, the U.K. passed legislation giving effect to the trade and cooperation agreement, with the E.U. expected to formally adopt the agreement in early 2021. The agreement sets out certain procedures for approval and recognition of medical products in each jurisdiction. Brexit could lead to legal uncertainty and potentially divergent national laws and regulations as the UK determines which EU laws to replace or replicate and may create logistical complications with respect to the movement and delivery of our products, which undergo certain manufacturing steps in the United Kingdom. Given the lack of comparable precedent, it is unclear what financial, trade, regulatory and legal implications the withdrawal of the UK from the EU would have and how such withdrawal would affect us. Several of our contract manufacturers are located in the UK. Any of these effects of Brexit,

24

Table of Contents

among others, could adversely affect our business, financial condition and operating results. In the longer term, Brexit could materially impact the future regulatory regime which applies to medical devices and their approval in the UK.

​

U.S. Foreign Corrupt Practices Act

​

The U.S. Foreign Corrupt Practices Act, or FCPA, prohibits U.S. corporations and their representatives from offering, promising, authorizing or making corrupt payments, gifts or transfers to any foreign government official, government staff member, political party or political candidate in an attempt to obtain or retain business abroad. The FCPA also obligates companies whose securities are listed in the United States to comply with accounting provisions requiring the company to maintain books and records that accurately and fairly reflect all transactions of the corporation, including international subsidiaries, and to devise and maintain an adequate system of internal accounting controls for international operations. Activities that violate the FCPA, even if they occur wholly outside the United States, can result in criminal and civil fines, imprisonment, disgorgement, oversight, and debarment from government contracts.

​

UK Bribery Act and other anti-corruption laws

​

The UK Bribery Act 2010 and other applicable ant-corruption laws that apply in countries where we do business, generally prohibit us and our employees and intermediaries from authorizing, promising, offering, or providing, directly or indirectly, improper or prohibited payments, or anything else of value, to government officials or other persons to obtain or retain business or gain some other business advantage. Under the UK’s Bribery Act, we may also be liable for failing to prevent a person associated with us from committing a bribery offense.

​

We are also subject to other laws and regulations governing our international operations, including regulations administered by the governments of the UK and authorities in the EU, including applicable export control regulations, economic sanctions and embargoes on certain countries and persons, anti-money laundering laws, import and customs requirements and currency exchange regulations, collectively referred to as trade control laws. Failure to comply with the UK’s Bribery Act, and other anti-corruption laws and trade control laws could subject us to criminal and civil penalties, disgorgement and other sanctions and remedial measures, and legal expenses.

Employees and Human Capital Resources

​

As of December 31, 2020, we had 82 employees, of whom over half hold Ph.D., M.D., master’s degree or other post-graduate degree, and all of whom are located in the United States. The majority of employees are in operations and research and development positions aligned with our corporate focus. None of our employees are represented by a labor union or covered by a collective bargaining agreement. We consider our relationship with our employees to be good.

​

We compete in the highly competitive medical technology industry. We believe that our future success largely depends upon our continued ability to attract and retain highly skilled employees, as well as highly qualified management and technical personnel. Employee engagement is important to us and we focus on continuously enhancing our corporate culture and individual development programs. We have surveyed our employees around culture, engagement, work environment, communication and other topics and work to incorporate and respond to their feedback. We expect to conduct similar survey and response efforts in the future. We conduct frequent company calls in an effort to update all employees on what is happening in various departments to ensure our employees understand our strategic vision as well as our day-to-day objectives. We provide our employees with market competitive pay and bonuses, opportunities for equity ownership, professional development and training programs that enable continued learning and growth and a robust employment package that seek to promote well-being across all aspects of our employees’ lives, including health care, retirement planning and paid time off. Our equity plans include an employee stock purchase plan and restricted stock units granted under our broad-based stock incentive programs.

​

Through our history of technological innovation, we appreciate the importance of retention, growth and development of our employees. We continue to be committed to an inclusive culture which values diversity, equality, opportunity, and respect.

Corporate Information

​

We were originally incorporated as ASN Technologies, Inc. in Nevada on June 26, 2014. On December 7, 2015, pursuant to the Merger Agreement and the transactions contemplated thereby, or the Acquisition, we acquired Senseonics, Incorporated, a medical technology company focused on the design, development and commercialization of glucose monitoring systems to improve the lives of people with diabetes by enhancing their ability to manage their disease with relative ease and accuracy. From its inception in 1996 until 2010, Senseonics, Incorporated devoted substantially all of its resources to researching various sensor technologies and platforms. Beginning in 2010, the company narrowed its focus to designing, developing and refining a commercially viable glucose monitoring system.

​

In connection with the Acquisition, we reincorporated in Delaware and changed our name to Senseonics Holdings, Inc. Upon the closing of the Acquisition, Senseonics, Incorporated merged with a wholly owned subsidiary of ours formed solely for that purpose and became our wholly owned subsidiary.

​

Our principal executive offices are located at 20451 Seneca Meadows Parkway, Germantown, Maryland 20876-7005 and our telephone number is (301) 515-7260. Our common stock is listed on the NYSE American under the symbol “SENS.”

Risks Relating to our Business and our Industry

​

We have incurred significant operating losses since inception and cannot assure you that we will ever achieve or sustain profitability.

​

Since our inception, we have incurred significant net losses, including net losses of $175.2 million, $115.5 million, and $94.0 million for the years ended December 31, 2020, 2019 and 2018, respectively. As of December 31, 2020, we had an accumulated deficit of $648.5 million. To date, we have financed our operations primarily through sales of our equity securities and debt financings. We have devoted substantially all of our resources to the research and development of our products, including conducting clinical trials, and the commercial launch of Eversense in the United States and Eversense and Eversense XL in Europe, the Middle East, and Africa (EMEA).

​

To implement our business strategy we need to, among other things, gain regulatory approval in other regions where we intend to sell our products, expand our commercial launch in the United States and Europe, and develop future generations of Eversense. We have never been profitable and do not expect to be profitable for at least the next several years. We expect our expenses to increase significantly as we pursue these objectives. The extent of our future operating losses and the timing of profitability are highly uncertain, and we expect to continue incurring expenses and operating losses over the next several years. Any additional operating losses may have an adverse effect on our stockholders' equity, and we cannot assure you that we will ever be able to achieve profitability. Even if we achieve profitability, we may not be able to sustain or increase profitability on a quarterly or annual basis. Our failure to become and remain profitable would depress the value of our company and could impair our ability to raise capital, expand our business, maintain our development efforts, obtain regulatory approvals, diversify our product offerings or continue our operations.

​

Our collaboration and commercialization agreement with Ascensia to market Eversense may not be successful.

​

We have entered into a collaboration and commercialization agreement with Ascensia, pursuant to which we have granted Ascensia the exclusive right to distribute Eversense worldwide, subject to initial exceptions based on our other current exclusive distribution agreements. Pursuant to this agreement, our future success will be dependent on Ascensia effectively marketing and selling Eversense. We expect that the substantial majority of our future revenue will come pursuant to this agreement in future years. If Ascensia fails to perform satisfactorily under this agreement, including among other things if they are delayed or unsuccessful in growing the adoption of our product, our commercialization efforts and financial results would be directly and adversely affected.

​

The agreement is terminable by Ascensia under a number of circumstances, including if Eversense 180-day product is not approved in the United States by August 31, 2021 or if we undergo a change of control. The agreement is terminable by either party if the other party materially breaches its obligations under the agreement; provided, however, that if Ascensia is unable to achieve the specified minimum spending or revenue targets described above, then we will only have the right to covert Ascensia’s exclusive rights to nonexclusive rights, which may make it difficult for us to successfully engage with another commercial partner. The agreement is also terminable by either party if the other party undergoes bankruptcy, dissolution or winding up.

​

We cannot guarantee this agreement with Ascensia will be successful, that it will continue, or that we will be able to achieve or maintain any particular volume of sales under the agreement or increase the volume of sales at a satisfactory pace or at all from this relationship in the future.

​

Our collaboration and commercialization agreement with Ascensia and the terms of our recent debt and preferred stock transactions may discourage a change of control of our company.

​

The terms of our agreements with Ascensia and PHC may discourage a third party from acquiring, or attempting to acquire, control of our company, even if a change of control was considered favorable by some or all of our stockholders. For example, because of the exclusivity of the distribution arrangements with Ascensia and the minimum five-year term of that exclusivity (which may be extended under certain circumstances), prospective strategic acquirors may be unwilling to undertake an acquisition of our company. In addition, under the terms of the PHC Notes

28

Table of Contents

and our convertible preferred stock, we may be required to make significant payments to redeem these notes and to satisfy liquidation preference of our convertible preferred stock upon a change of control.

​

Our business, product sales and results of operations could be adversely affected by the effects of health epidemics, including the recent COVID-19 outbreak, in regions where we or third parties distribute our products or where we or third parties on which we rely have significant manufacturing facilities, concentrations, clinical trial sites or other business operations. The COVID-19 pandemic has and may continue to, materially affect our operations, including at our headquarters in Maryland and at our clinical trial sites, as well as the business or operations of our manufacturers, distributors or other third parties with whom we conduct business.

​

Our business could be adversely affected by health epidemics in regions where we sell products, where we have concentrations of clinical trial sites or other business operations, and could cause significant disruption in the operations of third-party manufacturers and distributors upon whom we rely.

​

For example, in December 2019, a novel strain of coronavirus, SARS-CoV-2, causing a disease referred to as COVID-19, was reported to have surfaced in Wuhan, China. Since then, COVID-19 has spread to multiple countries, including the United States and several European countries. Our headquarters is located in Maryland, and our contract manufacturers are located in Germany, the United Kingdom and the United States. Our distributors are located in the United States and various countries in Europe.

​

In March 2020, the World Health Organization declared the COVID-19 outbreak a pandemic, and the U.S. government imposed travel restrictions on travel between the United States, Europe and certain other countries. Further, the President of the United States declared the COVID-19 pandemic a national emergency, invoking powers under the Stafford Act, the legislation that directs federal emergency disaster response. Similarly, the Governor of Maryland has issued an order closing all non-essential businesses, which took effect on March 23, 2020. Substantially all of our workforce is now working from home either all or substantially all of the time. The effects of the Maryland order and our work-from-home policies may negatively impact productivity, disrupt our business and delay our clinical programs, regulatory and commercialization timelines, the magnitude of which will depend, in part, on the length and severity of the restrictions and other limitations on our ability to conduct our business in the ordinary course. These and similar, and perhaps more severe, disruptions in our operations could negatively impact our business, operating results and financial condition.

​

Quarantines, shelter-in-place and similar government orders, or the perception that such orders, shutdowns or other restrictions on the conduct of business operations could occur, related to COVID-19 or other infectious diseases could impact personnel at third-party manufacturing facilities in the United States and other countries, or the availability or cost of materials, which would disrupt our supply chain. In particular, some of our suppliers of certain materials used in the production of our sensors and transmitters are located in Germany, the United Kingdom, China, Japan and the United States. For example, any manufacturing supply interruption of Eversense or future generation products, could adversely affect our ability to conduct planned clinical trials and commercialization activities.

​

Sales and demand for Eversense have been and may be adversely affected by the global COVID-19 pandemic. Disruptions in the distributions of Eversense could result if patients are physically quarantined, if physicians restrict access to their facilities for a material period of time, if we are unable to train new physicians, if patients are unable or unwilling to visit health care providers, or if health care providers prioritize treatment of acute or communicable illnesses over diabetes management. At various times during the COVID-19 pandemic, (i) our or our partners’ ability to visit physician offices have been restricted, and (ii) insertions of Eversense have been adversely impacted. During the pandemic, these and other risks could recur or continue. In addition, in the spring of 2020 we announced changes in our ability to market Eversense in the U.S., substantially reduced our sales and marketing capabilities, and limited or ceased our efforts to secure new Eversense patients in the U.S. The impact of these actions on patients and health care providers could delay or negatively impact our ability to stabilize and grow sales of Eversense in the U.S.

​

In addition, our clinical trials may be affected by the COVID-19 pandemic. Clinical site initiation and patient enrollment may be delayed due to prioritization of hospital resources toward the COVID-19 pandemic. Some patients may not be able to comply with clinical trial protocols if quarantines impede patient movement or interrupt healthcare

29

Table of Contents

services. Similarly, our ability to recruit and retain patients and principal investigators and site staff who, as healthcare providers, may have heightened exposure to COVID-19 and adversely impact our clinical trial operations.

​

The spread of COVID-19, which has caused a broad impact globally, may materially affect us economically. While the potential economic impact brought by, and the duration of, COVID-19 may be difficult to assess or predict, a widespread pandemic could result in significant disruption of global financial markets, reducing our ability to access capital, which could negatively affect our liquidity. In addition, a recession or market correction resulting from the spread of COVID-19 could materially affect our business and the value of our common stock.

​

The review of our products by the FDA and other regulators has been and may continue to be adversely affected by the COVID-19 pandemic. On September 30, 2020 we submitted a PMA supplement application to extend the wearable life of the Eversense CGM System to 180 days to the FDA. Following the submission of the PMA, we have received communication from the FDA advising us that the reallocation of agency resources to address Emergency Use Authorization (EUA) applications for products related to the COVID-19 public health emergency is affecting marketing application reviews, including the Eversense 180-day product. Based on a February 19, 2021 communication, we understand that the FDA expects to assign a reviewer, and that our PMA will be placed under review, no later than April 15, 2021. Based on the passage of time and this new information from the FDA, we are anticipating approval no earlier than the second half of 2021. The timing to completion and outcome of such a review is uncertain, as is the impact of COVID-19 on agency review timelines or possible delays. A delay in the approval of our 180-day product in the U.S. could delay Ascensia from being able to market a product with longer duration and other additional patient benefits to the U.S. market and could adversely affect our net revenues and financial results.

​

The global pandemic of COVID-19 continues to rapidly evolve. The ultimate impact of the COVID-19 pandemic or a similar health epidemic is highly uncertain and subject to change. We do not yet know the full extent of potential delays or impacts on our business, our clinical trials, commercialization efforts, healthcare systems or the global economy as a whole. However, these effects could have a material impact on our operations, and we will continue to monitor the COVID-19 situation closely.

​

We have limited commercialization experience in the United States and Europe. If we are unable to successfully expand our commercialization of Eversense in the United States and Europe, or if Ascensia experiences difficulties is establishing support for Eversense, our business will be harmed.

​

We have limited commercialization experience in both the United States and Europe. We have invested substantially all of our efforts and financial resources to the development and commercialization of Eversense. Our ability to generate revenue from our products will depend heavily on successful commercialization of products in the United States and Europe, including through our new collaboration with Ascensia, and on continuing development of future generations of our Eversense system. The success of any products that we develop will depend on several factors, including:

​

30

Table of Contents

​

Our revenue is dependent, in part, upon the size of the markets in the territories for which we have regulatory approval, the accepted price for the product, the ability to obtain coverage and reimbursement, and whether we own the commercial rights for that territory. If the number of people with diabetes we target is not as significant as we estimate or the treatment population is narrowed by competition, physician choice or treatment guidelines, we may not generate significant revenue from sales of such products.

​

Our revenue is also dependent on the success of Ascensia in commercializing our product. Our product is a new product for Ascensia globally and they must additionally establish certain functions of their U.S. commercial organization to successfully market and sell our CGM system. If Ascensia experiences difficulties or delays in establishing sales and other functions that are required to support the product or adjusting to the requirements of supporting our product, there could be a materially negative impact on our net revenues from Eversense.

​

Approval in the United States by the FDA or by a regulatory agency in another country does not guarantee approval by the regulatory authorities in other countries or jurisdictions or ensure approval for the same conditions of use. In addition, clinical trials conducted in one country may not be accepted by regulatory authorities in other countries. Approval processes vary among countries and can involve additional product testing and validation and additional administrative review periods. If we do not achieve one or more of these approvals in a timely manner or at all, we could experience significant delays or an inability to fully commercialize Eversense and achieve profitability.

​

Both before and after a product is commercially released, we will have ongoing responsibilities under U.S. and EU regulations. We will also be subject to periodic inspections by the FDA, the corresponding Notified Body in the European Union and EEA and comparable foreign authorities to determine compliance with regulatory requirements, such as the Quality System Regulation, or QSR, of the FDA, medical device reporting regulations, vigilance in reporting of adverse events and regulations regarding notification, corrections, and recalls. These inspections can result in observations or reports, warning letters or other similar notices or forms of enforcement action. If the FDA, the corresponding Notified Body in the European Union and EEA or any comparable foreign authority concludes that we are not in compliance with applicable laws or regulations, or that any of our products are ineffective or pose an unreasonable health risk, such authority could ban these products, suspend or cancel our marketing authorizations, impose "stop-sale" and "stop-import" orders, refuse to issue export certificates, detain or seize adulterated or misbranded products, order a recall, repair, replacement, correction or refund of such products, or require us to notify health providers and others that the products present unreasonable risks of substantial harm to the public health. Discovery of previously unknown problems with our product's design or manufacture may result in restrictions on the use of Eversense, restrictions placed on us or our suppliers, or withdrawal of an existing regulatory clearance for Eversense. The FDA, the corresponding Notified Body in the European Union and EEA or comparable foreign authorities may also impose operating restrictions, enjoin and restrain certain violations of applicable law pertaining to medical devices, assess civil or criminal penalties against our officers, employees or us, or recommend criminal prosecution of our company. Adverse regulatory action may restrict us from effectively marketing and selling our products. In addition, negative publicity and product liability claims resulting from any adverse regulatory action could have a material adverse effect on our business, financial condition, and operating results.

​

Foreign governmental regulations have become increasingly stringent and more extensive, and we may become subject to even more rigorous regulation by foreign governmental authorities in the future. Penalties for a company's noncompliance with foreign governmental regulation could be severe, including revocation or suspension of a company's business license and civil or criminal sanctions. In some jurisdictions, such as Germany, any violation of a law related to medical devices is also considered to be a violation of unfair competition law. In such cases, governmental authorities, our competitors and business or consumer associations may then file lawsuits to prohibit us from commercializing Eversense in such jurisdictions. Our competitors may also sue us for damages. Any domestic or foreign governmental law or regulation imposed in the future may have a material adverse effect on our business, financial condition and operating results.

We are dependent on one product, Eversense. Our success depends on our ability to continue to develop, commercialize and gain market acceptance for our products.

​

Our current business strategy is highly dependent on the successful commercialization of Eversense and achieving and maintaining market acceptance. In order to sell Eversense to people with diabetes, we or our commercialization partners must educate them, their caregivers and healthcare providers that Eversense is an attractive alternative to competitive products for the monitoring of glucose levels, including SMBG, as well as other competitive CGM systems and alternatives to CGM methodologies. Market acceptance and adoption of Eversense depends on educating people with diabetes, as well as their caregivers and healthcare providers, as to the distinct features, ease-of-use, positive lifestyle impact, and other perceived benefits of Eversense as compared to competitive products.

​

Achieving and maintaining market acceptance of Eversense could be negatively impacted by many factors, including:

​

​

In addition, Eversense may be perceived by people with diabetes, their caregivers or healthcare providers to be more complicated or less effective than traditional monitoring methodologies, including SMBG or CGM systems which require less calibration, and people may be unwilling to change their current regimens.

​

Moreover, healthcare providers tend to be slow to change their medical treatment practices because of perceived liability risks arising from the use of new products and the uncertainty of third-party payor reimbursement. Accordingly, healthcare providers may not recommend Eversense unless and until there is sufficient evidence to convince them to alter the treatment methods they typically recommend, such as receiving recommendations from prominent healthcare providers or other key opinion leaders in the diabetes treatment community.

​

If we are not successful in educating people with diabetes of the benefits of Eversense, or if we are unable to achieve the support of caregivers and healthcare providers or widespread market acceptance for Eversense, then our sales potential, strategic objectives and profitability could be negatively impacted, which would adversely affect our business, financial condition and operating results.

If we do not enhance our product offerings through our research and development efforts, we may fail to effectively compete or become profitable.

​

In order to capture and grow market share in the intensively managed diabetes market, we will need to enhance and broaden our product offerings in response to the evolving demands of people with diabetes and healthcare providers, as well as competitive pressures and technologies. These development needs include additional features, extended product life and other attributes we believe may be desired by patients. We may not be successful in developing, obtaining regulatory approval for, or marketing future versions of Eversense. In addition, notwithstanding our market research efforts, our future products may not be accepted by people with diabetes, their caregivers, healthcare providers or third-party payors who reimburse people with diabetes for Eversense and healthcare providers for their services. The success of Eversense or future versions of Eversense will depend on numerous factors, including our ability, and the ability of our commercial partners, to:

​

​

If we fail to generate demand by developing products that incorporate features requested by people with diabetes, their caregivers or healthcare providers, or if we do not obtain regulatory clearance or approval for future versions of Eversense in time to meet market demand, we may fail to generate sales sufficient to achieve or maintain profitability. We have in the past experienced, and we may in the future experience, delays in various phases of product development, approval and commercial launch, including during research and development, regulatory submission and approval, manufacturing, limited release testing, marketing and customer education efforts. Any delays in our anticipated product launches may significantly impede our ability to successfully compete in our markets. In particular, such delays could cause customers to delay or forego purchases of our products, or to purchase our competitors' products. Even if we are able to successfully develop future versions of Eversense when anticipated, these products may not produce sales in excess of the costs of development, and they may be quickly rendered obsolete by the changing preferences of people with diabetes or the introduction by our competitors of products embodying new technologies or features.

​

Failure to secure or retain coverage or adequate reimbursement for Eversense or future versions of Eversense systems, including the related insertion and removal procedures, by third-party payors, and an inability of patients to be able to access the product, could adversely affect our business, financial condition and operating results.

​

We plan to derive nearly all of our revenue from sales of Eversense in the United States and Europe and expect to do so for the next several years. Patients who receive treatment for their medical conditions and their healthcare providers generally rely on third party payors to reimburse all or part of the costs associated with their medical treatment, including healthcare providers' services. As a result, access to coverage and adequate reimbursement for Eversense by third-party payors is essential to the acceptance of our products by people with diabetes. Similarly, healthcare providers may choose not to order a product unless third-party payors cover and reimburse a substantial portion of the product. Coverage determinations and reimbursement levels of both our products and the healthcare provider's performance of the insertion and removal procedures are critical to the commercial success of our product, and if we or our commercial partners are not able to secure positive coverage determinations and reimbursement levels for our products or the insertion and removal procedures, our business would be materially adversely affected.

​

33

Table of Contents

Within and outside the United States, reimbursement is obtained from a variety of sources, including government sponsored and private health insurance plans. These third-party payors determine whether to provide reimbursement for specific products and procedures. A third-party payor's decision to provide coverage for our products does not imply that an adequate reimbursement rate will be obtained. Further, one third-party payor's decision to cover our products does not assure that other payors will also provide coverage for the products or will provide coverage at an adequate reimbursement rate. In addition, there may be significant delays in obtaining a reimbursement determination, and coverage, if granted, may be more limited than the purposes for which the product is cleared by the FDA, the corresponding Notified Body in the European Union and EEA or other foreign regulatory authorities. Moreover, eligibility for reimbursement does not imply that any product will be paid for in all cases or at a rate that covers its associated costs, including research, development, manufacture, sale and distribution. For example, payment rates may vary according to the use of the product and the clinical setting in which it is used, may be based on payments allowed for lower cost products that are already reimbursed, and may be incorporated into existing payments for other services. Net prices for products may be reduced by mandatory discounts or rebates required by government healthcare programs or third-party payors and by any future relaxation of laws that presently restrict imports of products from countries where they may be sold at lower prices.

​

Private insurance companies and other private, third-party payors set payor-specific reimbursement policies. The extent of coverage and the rate of reimbursement varies on a payor-by-payor basis. Most of the largest private third-party payors, in terms of the number of covered lives, have issued coverage policies for the category of CGM devices. These policies include varied coverage requirements regarding patient condition and characteristics. Many of these coverage policies reimburse for CGM systems under durable medical equipment benefits, which are restrictive in nature and require the healthcare provider or supplier to comply with extensive documentation and other requirements. In addition, those third-party payors that cover CGM products may and have included limitations as to the patient conditions and characteristics eligible for coverage and may adopt different coverage and reimbursement policies for our products, which could also diminish payments for Eversense. It is possible that some third-party payors will not offer any coverage for our products.

​

Eversense is an implantable medical device in the clinic setting and thus follows a different reimbursement path when compared to the current CGM class. Some payors will adopt a payment methodology that will bundle payment of device and procedure back to the implanting clinic. Other payors may choose to reimburse device and procedure separately. Without a Category 1 code to define the payment process, there will be some heterogeneity in this process. Given this heterogeneity, we will have to work closely with certified clinics to keep abreast of which process to follow and what to expect. This will be disruptive to some clinics and could delay product uptake until the process of payment becomes more homogenous and well defined for clinics to follow. Until a steady state is reached, delays in processing and clinic operating coordination could result in the loss of sales, which could negatively affect our business, financial condition and operating results.

​

Third-party payors, whether foreign or domestic, or governmental or commercial, are developing increasingly sophisticated methods of controlling healthcare costs by imposing lower payment rates and negotiating reduced contract rates, among others. As such, we believe that future coverage and reimbursement may be subject to increased restrictions, such as additional preauthorization requirements, both in the United States and in international markets. Our dependence on the commercial success of our Eversense products makes us particularly susceptible to any cost containment or reduction efforts. If third-party coverage and reimbursement of products for which we may receive regulatory approval is not available or adequate in either the United States or international markets, or if our production costs increase faster than increases in reimbursement levels, we or our commercial partners may be unable to sell Eversense or future versions of Eversense profitably and our business would be adversely impacted.

​

In March 2019, we launched a patient access program, the Eversense Bridge Program, to assist those patients who do not have insurance coverage for Eversense, or whose insurance is denied or insufficient. Pursuant to this program, we provided financial assistance to eligible patients purchasing Eversense, which may have been substantial depending on a patient’s insurance coverage. We also assisted patients in their appeal of adverse coverage decisions made by insurance providers. In December 2020, we terminated the Eversense Bridge Program. We expect our partner Ascensia to implement a patient assistance program and related programs as part of its commercialization efforts. The lack of a patient assistance program, or a program’s design being ineffective, could adversely impact the sales of

34

Table of Contents

Eversense and, consequently our net revenues. In addition, we may not be able to recognize a substantial portion of the revenue related to Eversense insertions for the patients participating in these access programs. The amount of time required to obtain favorable coverage and reimbursement decisions, including navigating the appeals process with third-party payors, is uncertain, and we may see increased product utilization without corresponding recognized revenue. Our operating results may be adversely impacted if we are unable to obtain successful appeals or favorable coverage decisions by insurance providers, or if there are not effective patient access programs in place.

​

If important assumptions we have made about what people with intensively managed diabetes are seeking in a CGM system are inaccurate, our business and operating results may be adversely affected.

​

Our business strategy was developed based on a number of important assumptions about the diabetes industry in general, and the intensively managed diabetes market in particular, any one or more of which may prove to be inaccurate. For example, we believe that the benefits of CGM will continue to drive increased rates of market acceptance for products in this space. However, this trend is uncertain and limited sources exist to obtain reliable market data.

​

Another key element of our business strategy is utilizing market research to understand how people with diabetes are seeking to improve their diabetes therapy management. This strategy underlies our entire product design, marketing and customer support approach and is the basis on which we developed Eversense. However, our market research is based on interviews, focus groups and online surveys involving people with intensively managed diabetes, their caregivers and healthcare providers that represent only a small percentage of the overall intensively managed diabetes market. As a result, the attributes we incorporated into the Eversense system may not be reflective of what is desired by the various constituents in the diabetes market. Consequently, our estimates of our future market share and penetration may not be accurate and our sales may be less than estimated.

​

We operate in a very competitive industry and if we fail to compete successfully against our existing or potential competitors, many of whom have greater resources than we have, our sales and operating results may be negatively affected.

​

The market for CGM systems is developing and competitive, subject to rapid change and significantly affected by new product introductions. We compete with well-capitalized companies, some of which are publicly traded, that manufacture CGM systems including Dexcom, Medtronic and Abbott. Each of these companies has received approval from the FDA to market their respective CGM system. Dexcom’s CGM system was the first CGM system to be approved by the FDA for marketing as a non-adjunctive device, and Abbott’s Freestyle Libre was also approved for non-adjunctive use. Both Dexcom (G6) and Abbott (Freestyle Libre) systems have factory calibration, and do not require user calibration.

​

Dexcom has also received the first FDA iCGM indication allowing its Dexcom G6 to be interoperable with other diabetes tech devices such as insulin pumps. As the industry evolves, we anticipate encountering increasing competition from companies that integrate CGM with insulin pumps. Abbott also received an iCGM indication for their Freestyle Libre 2 product and we expect all other CGM companies to pursue an iCGM indication including Medtronic.

​

In addition to CGM providers, we also compete with providers of SMBG systems. Three companies currently account for a substantial share of the worldwide sales of SMBG systems: Roche Diabetes Care, a division of Roche Diagnostics; Abbott; and Ascensia Diabetes Care Holdings AG.

​

In addition to CGM providers, we also compete with providers of traditional SMBG systems, including Roche Diabetes Care, a division of Roche Diagnostics; Abbott; and Ascensia Diabetes Care Holdings AG. There are also a number of academic and other institutions involved in various phases of our industry's technology development.

​

Many of these competitors enjoy several advantages over us, including:

​

35

Table of Contents

​

In addition, mergers and acquisitions in the diabetes industry may result in even more resources being concentrated among a smaller number of our competitors. Smaller or early-stage companies may also prove to be significant competitors, particularly through collaborative arrangements with large and established companies. These competitors also compete with us in recruiting and retaining qualified scientific and management personnel and establishing clinical trial sites and subject registration for clinical trials, as well as in acquiring technologies complementary to, or that may be necessary for, our programs.

​

If we are unable to effectively compete with our competitors, we may fail to meet our strategic objectives, and our business, financial condition and operating results could be harmed.

​

Competitive products or other technological innovations for the monitoring, treatment or prevention of diabetes may render our products less competitive or obsolete.

​

Our ability to achieve our strategic objectives will depend, among other things, on our ability to develop and commercialize products for the monitoring and management of diabetes that offer distinct features, have a longer duration than available alternatives, are easy-to-use, receive adequate coverage and reimbursement from third-party payors, include essential safety features and are more appealing than available alternatives. Our primary competitors, as well as a number of other companies, medical researchers and existing medical device companies are pursuing new delivery devices, delivery technologies, sensing technologies, procedures, drugs and other therapies for the monitoring, treatment and prevention of diabetes. For example, the National Institutes of Health and other supporters of diabetes research are continually seeking ways to prevent, cure or improve treatment of diabetes, which if successful could render glucose monitoring devices, like Eversense, obsolete. Any technological breakthroughs in diabetes monitoring, treatment or prevention could reduce the potential market for Eversense or render Eversense less competitive or obsolete altogether, which would significantly reduce our potential sales.

​

Because of the size of the diabetes market, we anticipate that companies will continue to dedicate significant resources to developing competitive products. The frequent introduction by competitors of products that are, or claim to be, superior to our products may create market confusion that may make it difficult to differentiate the benefits of our products over competitive products. In addition, the entry of multiple new products may lead some of our competitors to employ pricing strategies that could adversely affect the pricing of our products. If a competitor develops a product that competes with or is perceived to be superior to Eversense, or if a competitor employs strategies that place downward pressure on pricing within our industry, our sales may decline significantly or may not increase in line with our expectations, either of which would harm our business, financial condition and operating results.

​

The size and future growth in the market for CGM systems and CGM-related products has not been established with precision and may be smaller than we estimate, possibly materially. If our estimates and projections overestimate the size of this market, our sales growth may be adversely affected.

​

Our estimates of the size and future growth in the market for CGM systems and CGM-related products, including the number of people currently managing their diabetes with insulin who may benefit from and be amenable to using Eversense, is based on a number of internal and third-party studies, reports and estimates. In addition, our internal estimates are based in large part on current treatment patterns by healthcare providers using CGM systems and our belief that the incidence of diabetes in the United States and worldwide is increasing. While we believe these factors have historically provided and may continue to provide us with effective tools in estimating the total market for CGM systems and CGM related products and our products, these estimates may not be correct and the conditions supporting our

36

Table of Contents

estimates may change at any time, thereby reducing the predictive accuracy of these underlying factors. The actual incidence of diabetes, and the actual demand for our products or competitive products, could differ materially from our projections if our assumptions are incorrect. As a result, our estimates of the size and future growth in the market for our CGM systems may prove to be incorrect. If the actual number of people with diabetes who would benefit from Eversense and the size and future growth in the market for Eversense is smaller than we have estimated, it may impair our projected sales growth and have an adverse impact on our business.

​

Our ability to maintain and grow our revenue will depend on establishing a customer base and retaining a high percentage of our customer base.

​

A key to maintaining and growing our revenue will be establishing a customer base and retaining a high percentage of our customers due to the potentially significant revenue generated from ongoing purchases of disposable sensors. Ascensia intends to continue developing customer loyalty programs to help with retention aimed at patients, their caregivers and healthcare providers, which include patient ambassadors, training specific to Eversense, ongoing support by sales and clinical employees and 24/7 technical support and customer service. If demand for our products fluctuates as a result of the introduction of competitive products, changes in reimbursement policies, manufacturing problems, perceived safety issues with our or our competitors' products, the failure to secure regulatory clearance or approvals, or for other reasons, our ability to attract and retain customers could be harmed. The failure to retain a high percentage of our customers would negatively impact our business, financial condition and operating results.

​

We have limited operating history as a commercial-stage company and may face difficulties encountered by companies early in their commercialization in competitive and rapidly evolving markets.

​

Our experience as a commercial-stage company upon which to evaluate our business, future sales expectations and operating results is limited. In assessing our business prospects, you should consider the various risks and difficulties frequently encountered by companies early in their commercialization in competitive and rapidly evolving markets, particularly companies that develop and sell medical devices. These risks include our ability to:

​

​

Due to our limited operating history as a commercial-stage company, we may not have the institutional knowledge or experience to be able to effectively address these and other risks that may face our business. In addition, we may not be able to develop insights into trends that could emerge and negatively affect our business and may fail to respond effectively to those trends. As a result of these or other risks, we may not be able to execute key components of our business strategy, and our business, financial condition and operating results may suffer.

​

Table of Contents

We contract with third parties for the manufacture of Eversense. Risks associated with the manufacturing of our products could reduce our gross margins and negatively affect our operating results.

​

We do not have any manufacturing facilities or direct manufacturing personnel. We currently rely, and expect to continue to rely, on third parties for the manufacture of Eversense for commercial sale and development of future CGM products. Our business strategy depends on our third-party manufacturers' ability to manufacture Eversense in sufficient quantities and on a timely basis so as to meet consumer demand, while adhering to product quality standards, complying with regulatory requirements and managing manufacturing costs. We are subject to numerous risks relating to our reliance on the manufacturing capabilities of our third-party manufacturers, including:

​

​

These risks are likely to be exacerbated by our limited experience with Eversense and its manufacturing process. As demand for our products increases, our third-party suppliers will need to invest additional resources to purchase components, hire and train employees, and enhance their manufacturing processes. If our manufacturers fail to increase production capacity efficiently, our sales may not increase in line with our expectations and our operating margins could fluctuate or decline. Further, we may be required to fund capital investments at our third-party suppliers to support increased production capacity. In addition, although we expect some of our future versions of Eversense to share product features and components with our current Eversense and Eversense XL versions, manufacturing these future versions of Eversense may require the modification of production lines, the identification of new manufacturers for specific components, or the development of new manufacturing technologies. It may not be possible for us to manufacture these products at a cost or in quantities sufficient to make these future versions of Eversense commercially viable.

​

We depend on a limited number of third-party suppliers for the components of Eversense and the loss of any of these suppliers, or their inability to provide us with an adequate supply of materials, could harm our business.

​

We rely on third-party suppliers to supply and manufacture the components of our Eversense system. For our business strategy to be successful, our suppliers must be able to provide us with components and Eversense systems in sufficient quantities, in compliance with regulatory requirements and quality control standards, in accordance with agreed upon specifications, at acceptable costs and on a timely basis. Future increases in sales of Eversense, whether expected or unanticipated, could strain the ability of our suppliers to deliver an increasingly large supply of components and Eversense systems in a manner that meets these various requirements.

​

We generally use a small number of suppliers of components for our products. Depending on a limited number of suppliers exposes us to risks, including limited control over pricing, availability, quality and delivery schedules. Generally, we do not have long-term supply agreements with our suppliers, and, in many cases, we make our purchases on a purchase order basis. Under most of our supply and manufacturing agreements, we have no obligation to buy any given quantity of products, and our suppliers have no obligation to sell us or to manufacture for us any given quantity of components or products. As a result, our ability to purchase adequate quantities of components or our products may be limited, and we may not be able to convince suppliers to make components and products available to us. Additionally, our suppliers may encounter problems that limit their ability to supply components or manufacture products for us, including financial difficulties, damage to their manufacturing equipment or facilities, or product discontinuations. As a result, there is a risk that certain components could be discontinued and no longer available to us. We may be required to make significant "last time" purchases of component inventory that is being discontinued by the supplier to ensure

38

Table of Contents

supply continuity. If we fail to obtain sufficient quantities of high-quality components to meet demand for our products in a timely manner or on terms acceptable to us, we would have to seek alternative sources of supply. Because of factors such as the proprietary nature of our products, our quality control standards and regulatory requirements, we may not be able to quickly engage additional or replacement suppliers for some of our critical components. Failure of any of our suppliers to deliver components at the level our business requires could disrupt the manufacturing of our products and limit our ability to meet our sales commitments, which could harm our reputation and adversely affect our business.

​

We may also have difficulty obtaining similar components from other suppliers that are acceptable to the FDA or other regulatory agencies, and the failure of our suppliers to comply with strictly enforced regulatory requirements could expose us to regulatory action including warning letters, product recalls, and termination of distribution, product seizures or civil penalties. It could also require us to cease using the components, seek alternative components or technologies and modify our products to incorporate alternative components or technologies, which could result in a requirement to seek additional regulatory approvals. Any disruption of this nature or increased expenses could harm our commercialization efforts and adversely affect our operating results.

​

Our third-party suppliers operate primarily at facilities in a single location, and any disruption to these facilities could adversely affect our business and operating results.

​

Each of our third-party suppliers operates at a facility in a single location and substantially all of our inventory of component supplies and finished goods is held at these locations. We, and our suppliers, take precautions to safeguard facilities, including acquiring insurance, employing back-up generators, adopting health and safety protocols and utilizing off-site storage of computer data. However, vandalism, terrorism or a natural or other disaster, such as an earthquake, health epidemic, such as the coronavirus, fire or flood, could damage or destroy equipment or our inventory of component supplies or finished products, cause substantial delays in our operations, result in the loss of key information, or cause us to incur additional expenses. Our insurance may not cover our losses in any particular case. In addition, regardless of the level of insurance coverage, damage to our or our suppliers' facilities could harm our business, financial condition and operating results.

​

Various factors outside our direct control may adversely affect manufacturing, sterilization and distribution of our products.

​

The manufacture, sterilization and distribution of our products is challenging. Changes that our suppliers may make outside the purview of our direct control can have an impact on our processes, quality of our products and the successful delivery of products to our customers. Mistakes and mishandling are not uncommon and can affect supply and delivery. Some of these risks include:

​

​

If any of these risks were to materialize, our ability to provide our products to customers on a timely basis would be adversely impacted.

​

Potential complications from Eversense or future versions of Eversense may not be revealed by our clinical experience.

​

Based on our experience, complications from use of Eversense may include sensor errors, sensor failures or skin irritation under the adhesive dressing of the transmitter. Inflammation or redness, swelling, minor infection, and minor

39

Table of Contents

bleeding at the sensor insertion site are also possible risks with an individual's use of the device. However, if unanticipated side-effects result from the use of Eversense or future versions of Eversense, we could be subject to liability and our systems would not be widely adopted. Additionally, we have limited clinical experience with repeated use of our CGM system in the same patient or the same insertion site. We cannot assure you that long-term use would not result in unanticipated complications, even after the device is removed.

​

Undetected errors or defects in Eversense or future versions of Eversense could harm our reputation, decrease the market acceptance of Eversense or expose us to product liability claims.

​

Eversense or future versions of Eversense may contain undetected errors or defects. Disruptions or other performance problems with Eversense or future versions of Eversense, including our sensors not lasting for the full approved duration of use, may harm our reputation. If that occurs, we may incur significant costs, the attention of our key personnel could be diverted, or other significant customer relations problems may arise. We may also be subject to increased warranty and liability claims for damages related to errors or defects in Eversense or future versions of Eversense. A material liability claim or other occurrence that harms our reputation or decreases market acceptance of Eversense could harm our business and operating results. This risk exists even if a device is cleared or approved for commercial sale and manufactured in facilities licensed and regulated by the FDA or an applicable foreign regulatory authority. Any side effects, manufacturing defects, misuse or abuse associated with Eversense or future versions of Eversense systems could result in patient injury or death. The medical device industry has historically been subject to extensive litigation over product liability claims, and we cannot offer any assurance that we will not face product liability lawsuits.

​

The sale and use of Eversense or future versions of Eversense could lead to the filing of product liability claims if someone were to allege that Eversense or one of our products contained a design or manufacturing defect. A product liability claim could result in substantial damages and be costly and time consuming to defend, either of which could materially harm our business or financial condition. Product liability claims may be brought against us by people with diabetes, healthcare providers or others selling or otherwise coming into contact with our products, among others. If we cannot successfully defend ourselves against product liability claims, we will incur substantial liabilities and reputational harm. In addition, regardless of merit or eventual outcome, product liability claims may result in:

​

​

While we currently maintain product liability insurance covering claims up to $10.0 million per incident, we cannot assure you that such insurance would adequately protect our assets from the financial impact of defending a product liability claim. Any product liability claim brought against us, with or without merit, could increase our product liability insurance rates or prevent us from securing such insurance coverage in the future.

​

If there are significant disruptions in our information technology systems, our business, financial condition and operating results could be adversely affected.

​

The efficient operation of our business depends on our information technology systems. We rely on our information technology systems to effectively manage patient requisitions and data, customer service cases and replacement obligations, marketing data, accounting and financial functions, inventory and order management, product quality records, research and development data, and technical support functions. Despite our security measures, our information technology systems are vulnerable to damage or interruption from earthquakes, fires, floods and other natural disasters, terrorist attacks, attacks by computer viruses or hackers, power losses, and computer system or data

40

Table of Contents

network failures. In addition, our data management application and a variety of our software systems, including the software in our smart transmitter, are hosted by third-party service providers whose security and information technology systems are subject to similar risks, which could be subject to computer viruses or hacker attacks or other failures. If our or our third-party service provider's security systems are breached or fail, unauthorized persons may be able to obtain access to sensitive data. If we or our third-party service providers were to experience a breach compromising sensitive data, our brand and reputation could be adversely affected, and the use of our products could decrease.

​

The failure of our or our service providers' information technology systems or our transmitter's software to perform as we anticipate or our failure to effectively implement new information technology systems could disrupt our entire operation or adversely affect our products and could result in decreased sales, increased overhead costs, and product shortages, all of which could negatively affect our reputation, business, financial condition and operating results.

​

We may enter into collaborations, in-licensing arrangements, joint ventures, strategic alliances or partnerships with third parties that may not result in the development of commercially viable products or the generation of significant future revenues.

​

In the ordinary course of our business, we may enter into collaborations, in-licensing arrangements, joint ventures, strategic alliances, partnerships or other arrangements to develop products and to pursue new markets. Proposing, negotiating and implementing collaborations, in-licensing arrangements, joint ventures, strategic alliances or partnerships may be a lengthy and complex process. Other companies, including those with substantially greater financial, marketing, sales, technology or other business resources, may compete with us for these opportunities or arrangements. We may not identify, secure, or complete any such transactions or arrangements in a timely manner, on a cost-effective basis, on acceptable terms or at all. We have limited institutional knowledge and experience with respect to these business development activities, and we may also not realize the anticipated benefits of any such transaction or arrangement. In particular, these collaborations may not result in the development of products that achieve commercial success or result in significant revenues and could be terminated prior to developing any products.

​

Additionally, we may not be in a position to exercise sole decision-making authority regarding the transaction or arrangement, which could create the potential risk of creating impasses on decisions, and our future collaborators may have economic or business interests or goals that are, or that may become, inconsistent with our business interests or goals. It is possible that conflicts may arise with our collaborators, such as conflicts concerning the achievement of performance milestones, or the interpretation of significant terms under any agreement, such as those related to financial obligations or the ownership or control of intellectual property developed during the collaboration. If any conflicts arise with any future collaborators, they may act in their self-interest, which may be adverse to our best interest, and they may breach their obligations to us. For example, one of our vendors who provides a component to the Eversense sensor has communicated to us its belief that one of its employees should be named as a co-inventor on a related patent application. We have communicated to the third party that its employee should not be named as a co-inventor and its employee has not been named as a co-inventor to date. In addition, we may have limited control over the amount and timing of resources that any future collaborators devote to our or their future products. Disputes between us and our collaborators may result in litigation or arbitration which would increase our expenses and divert the attention of our management. Further, these transactions and arrangements will be contractual in nature and will generally be terminable under the terms of the applicable agreements and, in such event, we may not continue to have rights to the products relating to such transaction or arrangement or may need to purchase such rights at a premium.

​

If we enter into in-bound intellectual property license agreements, we may not be able to fully protect the licensed intellectual property rights or maintain those licenses. Future licensors could retain the right to prosecute and defend the intellectual property rights licensed to us, in which case we would depend on the ability of our licensors to obtain, maintain and enforce intellectual property protection for the licensed intellectual property. These licensors may determine not to pursue litigation against other companies or may pursue such litigation less aggressively than we would. Further, entering into such license agreements could impose various diligence, commercialization, royalty or other obligations on us. Future licensors may allege that we have breached our license agreement with them, and accordingly seek to terminate our license, which could adversely affect our competitive business position and harm our business prospects.

​

Table of Contents

We may seek to grow our business through acquisitions of complementary products or technologies, and the failure to manage acquisitions, or the failure to integrate them with our existing business, could harm our business, financial condition and operating results.

​

From time to time, we may consider opportunities to acquire other companies, products or technologies that may enhance our product platform or technology, expand the breadth of our markets or customer base, or advance our business strategies. Potential acquisitions involve numerous risks, including:

​

​

We have no current commitments with respect to any acquisition. We do not know if we will be able to identify acquisitions we deem suitable, whether we will be able to successfully complete any such acquisitions on favorable terms or at all, or whether we will be able to successfully integrate any acquired products or technologies. Our potential inability to integrate any acquired products or technologies effectively may adversely affect our business, operating results and financial condition.

We will need to generate significant sales to achieve profitable operations.

We intend to increase our operating expenses in connection with the commercialization of Eversense with our collaboration partner Ascensia, our ongoing research and development activities including the development of next generation products and the clinical trials for those products, and the commensurate development of our management and administrative functions. We will need to generate significant sales to achieve profitability, and we might not be able to do so. Even if we do generate significant sales, we might not be able to achieve, sustain or increase profitability on a quarterly or annual basis in the future. If our sales grow more slowly than we expect, or if our operating expenses exceed our expectations, our financial performance and operating results will be adversely affected.

​

Our operating results may fluctuate from quarter to quarter or year to year.

​

We have limited operating history as a commercial-stage company and we anticipate that there will be meaningful variability in our operating results among years and quarters, as well as within each year and quarter. Our operating results, and the variability of these operating results, will be affected by numerous factors, including:

​

Table of Contents

​

As a result of our lack of operating history as a commercial-stage company and Ascensia’s lack of experience selling CGM systems, and Eversense in particular, and due to the complexities of the industry and regulatory framework in which we operate, it will be difficult for us to forecast demand for our future products and to forecast our sales with any degree of certainty. For example, many of the products we will seek to develop and introduce in the future will require regulatory approval or clearance and import licenses before we can sell such products and given that the timing of such approvals, clearances or licenses may be uncertain, it will be difficult for us to predict sales projections for these products with any degree of certainty before such approvals, clearances or licenses are obtained. In addition, we will be increasing our operating expenses as we expand our business. Accordingly, we may experience substantial variability in our operating results from year to year and quarter to quarter. If our quarterly or annual operating results fall below the expectations of investors or securities analysts, the price of our common stock could decline substantially. Furthermore, any quarterly or annual fluctuations in our operating results may, in turn, cause the price of our common stock to fluctuate substantially. We believe that quarterly comparisons of our financial results are not necessarily meaningful and should not be relied upon as an indication of our future performance.

​

Covenants under the PHC Note Purchase Agreement and the indentures related to the 2023 Notes and the 2025 Notes may result in the acceleration of outstanding indebtedness and limit the manner in which we operate.

​

The PHC Note Purchase Agreement contains customary terms and covenants, including financial covenants, such as operating within an approved budget and achieving minimum revenue and liquidity targets, and negative covenants, such as limitations on indebtedness, liens, mergers, asset transfers, certain investing activities and other matters customarily restricted in such agreements. Most of these restrictions are subject to certain minimum thresholds and exceptions. The Note Purchase Agreement also contains customary events of default, after which the PHC Notes be due and payable immediately, including defaults related to payment compliance, material inaccuracy of representations and warranties, covenant compliance, material adverse changes, bankruptcy and insolvency proceedings, cross defaults to certain other agreements, judgments against the Company, change of control or delisting events, termination of any guaranty, governmental approvals, and lien priority.

​

In addition, the indentures related to the 2023 Notes and the 2025 Notes contain, and any future indebtedness we incur may contain, various negative covenants that restrict, among other things, our ability to:

​

​

Table of Contents

As a result, we are limited in the manner in which we conduct our business and we may be unable to engage in favorable business activities, repurchase shares of our common stock or finance future operations or capital needs.

​

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 depends on our future performance, which is subject to economic, financial, competitive and other factors beyond our control. Our business may not generate cash flow from operations in the future sufficient to service our debt and 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 selling assets, restructuring debt or obtaining additional equity capital on terms that may be onerous or highly dilutive. Our ability to refinance our 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 or engage in these activities on desirable terms, which could result in a default on our debt obligations.

​

Despite our current debt levels, subject to certain conditions and limitations, we may still incur substantially more debt or take other actions which would intensify the risks discussed above.

​

Despite our current consolidated debt levels, subject to certain conditions and limitations in the indentures related to the 2023 Notes and the 2025 Notes and PHC Notes, we may be able to incur substantial additional debt in the future, some of which may be secured debt. We may not be subject to any restrictions on incurrence of additional indebtedness under the terms of any future indebtedness. If new debt is added to our current debt levels, the related risks that we and they now face could intensify.

​

Prolonged negative economic conditions could adversely affect us, our customers and third-party suppliers, which could harm our financial condition.

​

We are subject to the risks arising from adverse changes in general economic and market conditions. Uncertainty about future economic conditions could negatively impact our existing and potential customers, adversely affect the financial ability of health insurers to pay claims, adversely impact our expenses and ability to obtain financing of our operations, and cause delays or other problems with key suppliers.

​

Healthcare spending in the United States and Europe has been, and is expected to continue to be, under significant pressure and there are many initiatives to reduce healthcare costs. As a result, we believe that some insurers are scrutinizing insurance claims more rigorously and delaying or denying coverage and reimbursement more often. Because the sale of Eversense will generally depend on the availability of third-party coverage and reimbursement, any delay or decline in coverage and reimbursement will adversely affect our sales.

​

Our business may be exposed to foreign exchange risks.

​

We incur some of our expenses and derive revenues from Eversense XL in currencies other than the U.S dollar. As a result, we are exposed to foreign currency exchange risk as our results of operations and cash flows are subject to fluctuations in foreign currency exchange rates. We currently do not engage in hedging transactions to protect against uncertainty in future exchange rates between particular foreign currencies and the U.S. dollar. Therefore, for example, an increase in the value of the U.S. dollar against the euro or the British pound could have a negative impact on our revenue and earnings growth as euro and British pound revenue and earnings, if any, are translated into U.S. dollars at a reduced value. We cannot predict the impact of foreign currency fluctuations, and foreign currency fluctuations in the future may adversely affect our financial condition, results of operations and cash flows.

Risks Related to Development of our Products

If we modify our approved product, we may need to seek additional approvals, which, if not granted, would prevent us from selling our modified products.

​

A component of our strategy is to continue to modify and upgrade our Eversense system, which requires approval by the FDA and analogous regulatory bodies in other jurisdictions. We may not be able to obtain additional regulatory approvals for new products or for modifications to, or additional indications for, our existing products in a timely fashion, or at all. Delays in obtaining future approvals, including potential delays in obtaining approval of our currently pending applications, would adversely affect our ability to introduce new or enhanced products in a timely manner, which in turn would harm our revenue and potential future profitability.

​

Any modifications to the Eversense that could significantly affect its safety or effectiveness, including significant design and manufacturing changes, or that would constitute a major change in its intended use, manufacture, design, components, or technology requires approval of a new premarket approval application, or PMA, or PMA supplement or similar modifications in other jurisdictions. However, certain changes to a PMA-approved device do not require submission and approval of a new PMA or PMA supplement, or appropriate modifications in other jurisdictions, and may only require notice to FDA in a PMA Annual Report, or similar notifications. In the U.S., the FDA requires every manufacturer to make this determination in the first instance, but the FDA may review any such decision. The FDA may not agree with our decisions regarding whether new approvals are necessary. Our products could be subject to recall if the FDA determines, for any reason, that our products are not safe or effective or that appropriate regulatory submissions were not made. Similar regulatory considerations apply outside the U.S. If new regulatory approvals are required, this could delay or preclude our ability to market the modified system.

Medical device development involves a lengthy and expensive process, with an uncertain outcome. We may incur additional costs or experience delays in completing, or ultimately be unable to complete, ongoing development for lifecycle management of our products.

​

While we have completed pivotal trials in Europe and the United States, we are and may need to conduct future clinical trials in order to develop new versions of our system or to comply with requirements for post-approval studies. For example, subject to regulatory clearance of our IDE, we are planning to initiate a pivotal trial to support a future PMA supplement for 365-day sensor. Clinical testing is expensive, difficult to design and implement, can take many years to complete and is inherently uncertain as to outcome. A failure of one or more clinical trials can occur at any stage of testing. Further, the outcomes of our earlier clinical trials may not be predictive of the success of later clinical trials, and interim results of a clinical trial do not necessarily predict final results. Moreover, clinical data is often susceptible to varying interpretations and analyses, and many companies that have believed their products performed satisfactorily in clinical trials have nonetheless failed to obtain marketing approval.

​

If we are unable to successfully complete clinical trials of Eversense or other testing, if the results of these trials or tests are not favorable or if there are safety concerns, we may:

​

​

Our development costs will also increase if we experience delays in testing or marketing approvals. Significant clinical trial delays also could allow our competitors to bring innovative products to market before we do and impair our ability to successfully commercialize our products.

Risks Related to Employee Matters and Managing our Growth

​

Our future success depends on our ability to retain key executives and to attract, retain and motivate qualified personnel.

​

We are highly dependent on the management, research and development, clinical, financial and business development expertise of Tim Goodnow, our Chief Executive Officer, Nick Tressler, our Chief Financial Officer, Mukul Jain, our Chief Operating Officer, Fran Kaufman, our Chief Medical Officer, and Mirasol Panlilio, our Vice President and General Manager, Global Commercial Operations, as well as the other members of our scientific and clinical teams. Although we have employment agreements with our executive officers, each of them may terminate their employment with us at any time and will continue to be able to do so. We do not maintain "key person" insurance for any of our executives or employees.

​

Recruiting and retaining qualified scientific and clinical personnel and, as we progress the development of our product pipeline toward scaling up for commercialization, manufacturing and sales and marketing personnel, will also be critical to our success. The loss of the services of our executive officers or other key employees could impede the achievement of our research, development and commercialization objectives and seriously harm our ability to successfully implement our business strategy. Furthermore, replacing executive officers and key employees may be difficult and may take an extended period of time because of the limited number of individuals in our industry with the breadth of skills and experience required to successfully develop, gain regulatory approval of and commercialize our products. Competition to hire from this limited pool is intense, and we may be unable to hire, train, retain or motivate these key personnel on acceptable terms given the competition among numerous medical device companies for similar personnel, many of which have greater financial and other resources dedicated to attracting and retaining personnel. We also experience competition for the hiring of scientific and clinical personnel from universities and research institutions. In addition, we rely on consultants and advisors, including scientific and clinical advisors, to assist us in formulating our research and development and commercialization strategy. Our consultants and advisors may be employed by employers other than us and may have commitments under consulting or advisory contracts with other entities that may limit their availability to us. If we are unable to continue to attract and retain high quality personnel, our ability to pursue our growth strategy will be limited.

​

Although it will be subject to restrictions on trading, a portion of the equity of our management team will not contain other contractual transfer restrictions. This liquidity may represent material wealth to such individuals and impact retention and focus of existing key members of management.

​

We expect to expand our development and regulatory capabilities and our marketing and distribution capabilities, and as a result, we may encounter difficulties in managing our growth, which could disrupt our operations.

​

As of December 31, 2020, we had 82 employees. As our commercialization progresses, we expect to experience significant growth in the number of our employees and the scope of our operations, particularly in the areas of research, product development, clinical sciences, regulatory affairs, supply chain, and marketing. To manage our anticipated future growth, we must continue to implement and improve our managerial, operational and financial systems, expand our facilities and continue to recruit and train additional qualified personnel. Due to our limited financial resources and the limited experience of our management team in managing a company with such anticipated growth, we may not be able to effectively manage the expansion of our operations or recruit and train additional qualified personnel. The expansion of our operations may lead to significant costs and may divert our management and business development resources. Any inability to manage growth could delay the execution of our business plans or disrupt our operations.

​

Additionally, we have and may undertake cost reduction plans, which may include reorganization of our workforce. These actions could disrupt the employee base, our ability to attract and retain qualified personnel, or cause other operational and administrative inefficiencies.

​

Table of Contents

Our employees, independent contractors, consultants, manufacturers and distributors may engage in misconduct or other improper activities, including non-compliance with regulatory standards and requirements.

​

We are exposed to the risk that our employees, independent contractors, consultants, manufacturers and distributors may engage in fraudulent conduct or other illegal activity. Misconduct by these parties could include intentional, reckless or negligent conduct or disclosure of unauthorized activities to us that violates FDA regulations, including those laws requiring the reporting of true, complete and accurate information to the FDA, manufacturing standards, federal and state healthcare laws and regulations, and laws that require the true, complete and accurate reporting of financial information or data. In particular, sales, marketing and business arrangements in the healthcare industry are subject to extensive laws and regulations intended to prevent fraud, kickbacks, self-dealing and other abusive practices. These laws and regulations may restrict or prohibit a wide range of pricing, discounting, marketing and promotion, sales commission, customer incentive programs and other business arrangements. Misconduct by these parties could also involve the improper use of individually identifiable information, including, without limitation, information obtained in the course of clinical trials, which could result in regulatory sanctions and serious harm to our reputation. We have adopted a code of business conduct and ethics, but it is not always possible to identify and deter misconduct, and the precautions we take to detect and prevent this activity may not be effective in controlling unknown or unmanaged risks or losses or in protecting us from governmental investigations or other actions or lawsuits stemming from a failure to be in compliance with such laws or regulations. If any such actions are instituted against us, and we are not successful in defending ourselves or asserting our rights, those actions could have a significant impact on our business, including the imposition of significant civil, criminal and administrative penalties, including, without limitation, damages, fines, disgorgement of profits, individual imprisonment, exclusion from participation in government healthcare programs, such as Medicare and Medicaid, integrity oversight and reporting obligations, and the curtailment or restructuring of our operations.

​

We may incur product liability losses, and insurance coverage may be inadequate or unavailable to cover these losses.

​

Our business exposes us to potential product liability claims that are inherent in the design, manufacture, testing and sale of medical devices. We could become the subject of product liability lawsuits alleging that component failures, manufacturing flaws, design defects or inadequate disclosure of product-related risks or product-related information resulted in an unsafe condition, injury or death to customers. In addition, the misuse of our products or the failure of customers to adhere to operating guidelines could cause significant harm to customers, including death, which could result in product liability claims. Product liability lawsuits and claims, safety alerts or product recalls, with or without merit, could cause us to incur substantial costs, and could place a significant strain on our financial resources, divert the attention of management from our core business, harm our reputation and adversely affect our ability to attract and retain customers, any of which could harm our business, financial condition and operating results.

​

Although we maintain third-party product liability insurance coverage, it is possible that claims against us may exceed the coverage limits of our insurance policies. Even if any product liability loss is covered by an insurance policy, these policies typically have substantial deductibles for which we are responsible. Product liability claims in excess of applicable insurance coverage would negatively impact our business, financial condition and operating results. In addition, any product liability claim brought against us, with or without merit, could result in an increase of our product liability insurance premiums. Insurance coverage varies in cost and can be difficult to obtain, and we cannot guarantee that we will be able to obtain insurance coverage in the future on terms acceptable to us or at all.

​

Risks Related to our Intellectual Property

​

Our ability to protect our intellectual property and proprietary technology is uncertain.

​

We rely primarily on patent, trademark and trade secret laws, as well as confidentiality and non-disclosure agreements, to protect our proprietary technologies. As of December 31, 2020, we held a total of approximately 519 issued patents and pending patent applications that relate to our CGM system. Our intellectual property portfolio includes 90 issued United States patents, 254 patents issued in countries outside the United States, and 175 pending patent applications worldwide. Our patents expire between 2021 and 2043, subject to any patent extensions that may be available for such patents. If patents are issued on our pending patent applications, the resulting patents are projected to expire on dates ranging from 2021 to 2043. We are also seeking patent protection for our proprietary technology in

47

Table of Contents

Europe, Japan, China, Canada, India, Australia and other countries and regions throughout the world. We have no pending U.S. trademark applications and 20 pending foreign trademark applications, as well as 14 U.S. trademark registrations and 116 foreign trademark registrations.

​

We have applied for patent protection relating to certain existing and proposed products and processes. Currently, several of our issued U.S. patents as well as various pending U.S. and foreign patent applications relate to the structure and operation of our CGM sensor and CGM systems, which are important to the functionality of our products. If we fail to timely file a patent application in any jurisdiction, we may be precluded from doing so at a later date. Furthermore, we cannot assure you that any of our patent applications will be approved in a timely manner or at all. The rights granted to us under our patents, and the rights we are seeking to have granted in our pending patent applications, may not provide us with any meaningful commercial advantage. In addition, those rights could be opposed, contested or circumvented by our competitors, or be declared invalid or unenforceable in judicial or administrative proceedings. The failure of our patents to adequately protect our technology might make it easier for our competitors to offer the same or similar products or technologies. Even if we are successful in receiving patent protection for certain products and processes, our competitors may be able to design around our patents or develop products that provide outcomes which are comparable to ours without infringing on our intellectual property rights. Due to differences between foreign and U.S. patent laws, our patented intellectual property rights may not receive the same degree of protection in foreign countries as they would in the United States. Even if patents are granted outside the United States, effective enforcement in those countries may not be available.

​

We rely on our trademarks and trade names to distinguish our products from the products of our competitors and have registered or applied to register many of these trademarks. For example, we have two pending applications in the United States for the "Eversense" trademark. We cannot assure you that our trademark applications will be approved in a timely manner or at all. Third parties also may oppose our trademark applications, or otherwise challenge our use of the trademarks. 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 devote additional resources to marketing new brands. Further, we cannot assure you that competitors will not infringe upon our trademarks, or that we will have adequate resources to enforce our trademarks.

​

We also rely on trade secrets, know-how and technology, which are not protectable by patents, to maintain our competitive position. We try to protect this information by entering into confidentiality agreements and intellectual property assignment agreements with our officers, employees, temporary employees and consultants regarding our intellectual property and proprietary technology. In the event of unauthorized use or disclosure or other breaches of those agreements, we may not have an adequate remedy to compensate us for our trade secrets or other proprietary information. In addition, our trade secrets may otherwise become known or be independently discovered by competitors. To the extent that our commercial partners, collaborators, employees and consultants use intellectual property owned by others in their work for us, disputes may arise as to the rights in the related or resulting know-how and inventions. If any of our trade secrets, know-how or other technologies not protected by a patent were to be disclosed to or independently developed by a competitor, our business, financial condition and results of operations could be materially adversely affected.

​

If a competitor infringes upon one of our patents, trademarks or other intellectual property rights, enforcing those patents, trademarks and other rights may be difficult and time consuming. Patent law relating to the scope of claims in the industry in which we operate is subject to rapid change and constant evolution and, consequently, patent positions in our industry can be uncertain. Even if successful, litigation to defend our patents and trademarks against challenges or to enforce our intellectual property rights could be expensive and time consuming and could divert management's attention from managing our business. Moreover, we may not have sufficient resources or desire to defend our patents or trademarks against challenges or to enforce our intellectual property rights. Litigation also puts our patents at risk of being invalidated or interpreted narrowly and our patent applications at risk of not issuing. Additionally, we may provoke third parties to assert claims against us. We may not prevail in any lawsuits that we initiate and the damages or other remedies awarded, if any, may not be commercially material. The occurrence of any of these events may harm our business, financial condition and operating results.

​

48

Table of Contents

Obtaining and maintaining our patent protection depends on compliance with various procedural, document submission, fee payment and other requirements imposed by government patent agencies, and our patent protection could be reduced or eliminated for non-compliance with these requirements.

​

Periodic maintenance fees, renewal fees, annuity fees, and various other government fees on patents and applications will be due to be paid to the United States Patent and Trademark Office, or USPTO, the European Patent Office, or EPO, and other foreign patent agencies over the lifetime of our owned patents and applications. The USPTO, the EPO and various foreign governmental patent agencies require compliance with several procedural, documentary, fee payment, and other similar provisions during the patent application process. While an inadvertent lapse can in many cases be cured by payment of a late fee or by other means in accordance with the applicable rules, there are situations in which noncompliance can result in abandonment or lapse of the patent or patent application, resulting in partial or complete loss of patent rights in the relevant jurisdiction. Non-compliance events that could result in abandonment or lapse of a patent or patent application include failure to respond to official actions within prescribed time limits, non-payment of fees and failure to properly legalize and submit formal documents. If we or our licensors or collaboration partners fail to maintain the patents and patent applications covering our proprietary technologies, our competitors might be able to enter the market earlier with similar products or technology, which would have an adverse effect on our business.

​

The medical device industry is characterized by patent litigation, and we could become subject to litigation that could be costly, result in the diversion of management's time and efforts, stop our development and commercialization measures, harm our reputation or require us to pay damages.

​

Our success will depend in part on not infringing the patents or violating the other proprietary rights of third parties. Significant litigation regarding patent rights exists in our industry. Our competitors in both the United States and abroad, many of which have substantially greater resources and have made substantial investments in competing technologies, may have applied for or obtained or may in the future apply for and obtain, patents that will prevent, limit or otherwise interfere with our ability to make and sell our products. The large number of patents, the rapid rate of new patent issuances, and the complexities of the technology involved increase the risk of patent litigation.

The medical device industry in general, and the glucose testing sector of this industry in particular, are characterized by the existence of a large number of patents and frequent litigation based on assertions of patent infringement. We are aware of numerous patents issued to third parties that may relate to the technology used in our business, including the design and manufacture of CGM sensors and CGM systems, as well as methods for continuous glucose monitoring. Each of these patents contains multiple claims, any one of which may be independently asserted against us. The owners of these patents may assert that the manufacture, use, sale or offer for sale of our CGM sensors or CGM systems infringes one or more claims of their patents. Furthermore, there may be additional patents issued to third parties of which we are presently unaware that may relate to aspects of our technology that such third parties could assert against us and materially and adversely affect our business. In addition, because patent applications can take many years to issue, there may be patent applications that are currently pending and unknown to us, which may later result in issued patents that third parties could assert against us and harm our business.

In preparation for commercializing our Eversense products, we are performing an analysis, the purpose of which is to review and assess publicly available information to determine whether third parties hold any valid patent rights that a well-informed court would more likely than not find that we would infringe by commercializing our products, understanding that there are risks and uncertainties associated with any litigation and no predictions or assurances can be made regarding the outcome of any such litigation. Although our review and analysis are not complete and subject to the express limitations in the preceding sentence, we are not aware of any such valid patent rights. Moreover, we have not previously performed an exhaustive review of this type, and we cannot be certain that it will not result in our locating patent rights relating to our products of which we were not previously aware.

​

49

Table of Contents

In the future, we could receive communications from various industry participants alleging our infringement of their intellectual property rights. Any potential intellectual property litigation could force us to do one or more of the following:

​

​

Patent litigation can involve complex factual and legal questions, and its outcome is uncertain. Any litigation or claim against us, even those without merit, may cause us to incur substantial costs, and could place a significant strain on our financial resources, divert the attention of management from our core business, stop our development and commercialization measures and harm our reputation. Further, as the number of participants in the diabetes market increases, the possibility of intellectual property infringement claims against us increases.

​

We may be subject to damages resulting from claims that we, or our employees, have wrongfully used or disclosed alleged trade secrets of our competitors or are in breach of non-competition or non-solicitation agreements with our competitors.

​

Many of our employees were previously employed at other medical device companies, including those that are our direct competitors or could potentially be our direct competitors. In some cases, those employees joined our company recently. We may be subject to claims that we, or our employees, have inadvertently or otherwise used or disclosed trade secrets or other proprietary information of these former employers or competitors. In addition, we may in the future be subject to allegations that we caused an employee to breach the terms of his or her non-competition or non-solicitation agreement. Litigation may be necessary to defend against these claims. Even if we successfully defend against these claims, litigation could cause us to incur substantial costs, and could place a significant strain on our financial resources, divert the attention of management from our core business and harm our reputation. If our defense to those claims fails, in addition to paying monetary damages, we may lose valuable intellectual property rights or personnel. There can be no assurance that this type of litigation will not occur, and any future litigation or the threat thereof may adversely affect our ability to hire additional direct sales representatives. A loss of key personnel or their work product could hamper or prevent our ability to commercialize Eversense or future versions of Eversense, which could have an adverse effect on our business, financial condition and operating results.

​

We may be subject to claims challenging the inventorship of our patents and other intellectual property.

​

We may be subject to claims that former employees, collaborators or other third parties have an interest in our owned patent rights, trade secrets, or other intellectual property as an inventor or co-inventor. For example, inventorship disputes may arise from conflicting obligations of employees, consultants or others who are involved in developing our medical devices or other technologies. Litigation may be necessary to defend against these and other claims challenging inventorship or our patent rights, trade secrets or other intellectual property. If we fail in defending any such claims, in addition to paying monetary damages, we may lose valuable intellectual property rights, such as exclusive ownership of, or right to use, intellectual property that is important to our medical devices and other technologies. Even if we are successful in defending against such claims, litigation could result in substantial costs and be a distraction to management and other employees. Any of the foregoing could have a material adverse effect on our business, financial condition, results of operations and prospects.

​

50

Table of Contents

We are subject to the patent laws of countries other than the United States, which may not offer the same level of patent protection and whose rules could seriously affect how we draft, file, prosecute and maintain patents, trademarks and patent and trademark applications.

​

Many countries, including certain countries in Europe, have compulsory licensing laws under which a patent owner may be compelled to grant licenses to third parties (for example, the patent owner has failed to "work" the invention in that country, or the third party has patented improvements). In addition, many countries limit the enforceability of patents against government agencies or government contractors. In these countries, the patent owner may have limited remedies, which could materially diminish the value of the patent. Moreover, the legal systems of certain countries, particularly certain developing countries, do not favor the aggressive enforcement of patent and other intellectual property protection which makes it difficult to stop infringement.

​

We cannot be certain that the patent or trademark offices of countries outside the United States will not implement new rules that increase costs for drafting, filing, prosecuting and maintaining patents, trademarks and patent and trademark applications or that any such new rules will not restrict our ability to file for patent protection. For example, we may elect not to seek patent protection in some jurisdictions in order to save costs. We may be forced to abandon specific patents due to a lack of financial resources.

​

Our intellectual property rights do not necessarily address all potential competitive threats or confer meaningful competitive benefits.

​

The degree of future protection afforded by our intellectual property rights is uncertain because intellectual property rights have limitations, and may not adequately protect our business, or permit us to maintain any competitive advantage. The following examples are illustrative:

​

​

Risks Related to our Legal and Regulatory Environment

​

Our products and operations are subject to extensive governmental regulation, and failure to comply with applicable requirements could cause our business to suffer.

​

The medical device industry is regulated extensively by governmental authorities, principally the FDA and corresponding state regulatory agencies in the United States and the European Commission and corresponding Notified Body in the European Union and the EEA. The regulations are very complex and are subject to rapid change and varying interpretations. Regulatory restrictions or changes could limit our ability to carry on or expand our operations or result in higher than anticipated costs or lower than anticipated sales. These governmental authorities enforce laws and regulations that are meant to assure product safety and effectiveness, including the regulation of, among other things:

​

​

The regulations to which we are subject are complex and have tended to become more stringent over time. Regulatory changes could result in restrictions on our ability to carry on or expand our operations, higher than anticipated costs or lower than anticipated revenues. Failure to comply with applicable regulations could jeopardize our ability to sell our products and result in enforcement actions such as fines, civil penalties, injunctions, warning letters, recalls of products, delays in the introduction of products into the market, refusal of the regulatory agency or other regulators to grant future clearances or approvals, and the suspension or withdrawal of existing approvals by such regulatory agencies. For example, in September 2019 we voluntarily initiated a recall of Eversense sensors that had not yet been implanted, due to premature loss of function due to inadequate hydration of the sensor’s glucose-sensing surface. This recall, as well as any of the above sanctions, could result in higher than anticipated costs or lower than anticipated sales and harm our reputation, business, financial condition and operating results.

​

The FDA regulatory clearance process and regulatory processes in other countries is expensive, time-consuming and uncertain, and the failure to obtain and maintain required regulatory clearances and approvals could prevent us from commercializing Eversense and future versions of Eversense.

​

Products that are approved through a PMA application generally need FDA approval before they can be modified, and similar approval processes are required in other jurisdictions where we may want to market our products. The process of obtaining regulatory approvals to market a medical device can be costly and time-consuming, and we may not be able to obtain these approvals on a timely basis, or at all for our products.

​

If the FDA requires us to go through a more rigorous examination for future products or modifications to existing products than we had expected, our product introductions or modifications could be delayed or canceled, which could cause our sales to decline or to not increase in line with our expectations.

​

The FDA can delay, limit or deny approval of a device for many reasons, including:

​

​

In addition, the FDA may change approval policies, adopt additional regulations or revise existing regulations, or take other actions which may prevent or delay approval of our product modifications under development.

​

Following the submission of the PMA for our 180-day product, we received communication from the FDA advising us that the reallocation of agency resources to address Emergency Use Authorization (EUA) applications for products related to the COVID-19 public health emergency is affecting marketing application reviews, including the Eversense 180-day product. Based on a February 19, 2021 communication, we understand that the FDA expects to assign a reviewer, and that our PMA will be placed under review, no later than April 15, 2021. Based on the passage of time and this new information from the FDA, we are anticipating approval no earlier than the second half of the year and note that the timing to completion and outcome of such a review is uncertain. Further reallocation of agency resources, shelter-in-place orders and other impacts from the COVID-19 pandemic are difficult to predict and could alter or delay the timing of response by the FDA regarding our submission.

Any delay in, or failure to receive or maintain, approval for our products could prevent us from generating revenue from these products or achieving profitability. Additionally, the FDA and other regulatory authorities have broad enforcement powers. Regulatory enforcement or inquiries, or other increased scrutiny on us, could dissuade some people with diabetes from using our products and adversely affect our reputation and the perceived accuracy and safety of our products.

​

If we or our third-party suppliers fail to comply with the FDA's good manufacturing practice regulations, this could impair our ability to market our products in a cost-effective and timely manner.

​

We and our third-party suppliers are required to comply with the FDA's QSR, which covers the methods and documentation of the design, testing, production, control, quality assurance, labeling, packaging, sterilization, storage and shipping of our products. The FDA audits compliance with the QSR through periodic announced and unannounced inspections of manufacturing and other facilities. The FDA may impose inspections or audits at any time. If we or our suppliers have significant non-compliance issues or if any corrective action plan that we or our suppliers propose in response to observed deficiencies is not sufficient, the FDA could take enforcement action against us. Any of the foregoing actions could impair our reputation, business, financial condition and operating results.

​

A recall of our products, or the discovery of serious safety issues with our products, could have a significant negative impact on us.

​

The FDA has the authority to require the recall of commercialized products in the event of material deficiencies or defects in design or manufacture or in the event that a product poses an unacceptable risk to health. Our third-party suppliers may, under their own initiative, recall a product if any material deficiency in a device is found. A government-mandated or voluntary recall by us or one of our third-party distributors could occur as a result of an unacceptable risk to health, component failures, manufacturing errors, design or labeling defects or other deficiencies and issues. For example, in September 2019 we voluntarily initiated a recall of Eversense sensors that had not yet been implanted, due to premature loss of function due to inadequate hydration of the sensor’s glucose-sensing surface. Recalls of any of our products would divert managerial and financial resources and have an adverse effect on our reputation, financial condition and operating results, which could impair our ability to produce our products in a cost-effective and timely manner.

​

Further, under the FDA's medical device reporting regulations, we are required to report to the FDA any incident in which our product may have caused or contributed to a death or serious injury or in which our product malfunctioned and, if the malfunction were to recur, would likely cause or contribute to death or serious injury. Repeated product malfunctions may result in a voluntary or involuntary product recall, which could divert managerial and financial resources, impair our ability to manufacture our products in a cost-effective and timely manner and have an adverse effect on our reputation, financial condition and operating results.

​

Any adverse event involving our products could result in future voluntary corrective actions, such as recalls or customer notifications, or regulatory agency action, which could include inspection, mandatory recall or other enforcement action. Any corrective action, whether voluntary or involuntary, will require the dedication of our time and capital, distract management from operating our business and may harm our reputation and financial results.

​

We are subject to the U.K. Bribery Act, the U.S. Foreign Corrupt Practices Act and other anti-corruption and anti-money-laundering laws, as well as export control laws, customs laws, sanctions laws and other laws governing our future global operations. If we fail to comply with these laws, we could be subject to civil or criminal penalties, other remedial measures and legal expenses, which could adversely affect our business, results of operations and financial condition.

​

Our current and future global operations will expose us to trade and economic sanctions and other restrictions imposed by the United States, the European Union and other governments and organizations. The U.S. Departments of Justice, Commerce, State and Treasury and other federal agencies and authorities have a broad range of civil and criminal penalties they may seek to impose against corporations and individuals for violations of economic sanctions laws, export control laws, the Foreign Corrupt Practices Act, or the FCPA, and other federal statutes and regulations,

including those established by the Office of Foreign Assets Control, or OFAC. In addition, the U.K. Bribery Act of 2010, or the Bribery Act, prohibits both domestic and international bribery, as well as bribery across both private and public sectors. An organization that "fails to prevent bribery" by anyone associated with the organization can be charged under the Bribery Act unless the organization can establish the defense of having implemented "adequate procedures" to prevent bribery. Under these laws and regulations, as well as other anti-corruption laws, anti-money-laundering laws, export control laws, customs laws, sanctions laws and other laws governing our operations, various government agencies may require export licenses, may seek to impose modifications to business practices, including cessation of business activities in sanctioned countries or with sanctioned persons or entities and modifications to compliance programs, which may increase compliance costs, and may subject us to fines, penalties and other sanctions. A violation of these laws or regulations could adversely impact our business, results of operations and financial condition.

​

We will implement and maintain policies and procedures designed to ensure compliance by us, and our directors, officers, employees, representatives, third-party distributors, consultants and agents with the FCPA, OFAC restrictions, the Bribery Act and other export control, anticorruption, anti-money-laundering and anti-terrorism laws and regulations. We cannot assure you, however, that our policies and procedures will be sufficient or that directors, officers, employees, representatives, third-party distributors, consultants and agents have not engaged and will not engage in conduct for which we may be held responsible, nor can we assure you that our business partners have not engaged and will not engage in conduct that could materially affect their ability to perform their contractual obligations to us or even result in our being held liable for such conduct. Violations of the FCPA, OFAC restrictions, the Bribery Act or other export control, anti-corruption, anti-money-laundering and anti-terrorism laws or regulations may result in severe criminal or civil sanctions, and we may be subject to other liabilities, which could have a material adverse effect on our business, financial condition, cash flows and results of operations.

​

We are subject to additional federal, state and foreign laws and regulations relating to our healthcare business; our failure to comply with those laws could have an adverse impact on our business.

​

Although we will not provide healthcare services, submit claims for third-party payor reimbursement, or receive payments directly from government health insurance programs or other third-party payors for Eversense, we are subject to broadly applicable federal, state, and foreign healthcare laws, including health care fraud and abuse and health information privacy and security laws, which could adversely impact our business. Such healthcare laws potentially applicable to our operations include:

​

​

The risk of our being found in violation of these laws and regulations is increased by the fact that the scope and enforcement of these laws is uncertain, many of them have not been fully interpreted by the regulatory authorities or the courts, their provisions are open to a variety of interpretations, or they vary country by country. We are unable to predict what additional federal, state or foreign legislation or regulatory initiatives may be enacted in the future regarding our business or the healthcare industry in general, or what effect such legislation or regulations may have on us. Federal, state or foreign governments may (i) impose additional restrictions or adopt interpretations of existing laws that could have a material adverse effect on us or (ii) challenge our current or future activities under these laws. Any of these challenges could impact our reputation, business, financial condition and operating results.

​

In February 2021, in conjunction with a communication to users regarding our distribution changes and securing customer and technical support, we made an unintended disclosure of certain user e-mail addresses to other users in Italy. To remedy this error, we communicated with affected parties and self-reported the disclosure to the appropriate authorities in Italy for GDPR. This disclosure could cause adverse reaction by users of our product and negative regulatory implications under GDPR. We are unable to predict at this time if there are any further impacts to this unintended disclosure.

​

Our activities, including our research, sales and marketing, and patient reimbursement support activities, may be subject to scrutiny under these laws. If our operations are found to be in violation of any of the laws described above or any other governmental regulations that apply to us now or in the future, we may be subject to penalties, including significant civil, criminal, and administrative penalties, damages, fines, disgorgement of profits, imprisonment, exclusion from governmental health care programs, such as Medicare and Medicaid, and the curtailment or restructuring of our operations, any of which could adversely affect our ability to operate our business and our financial results. Any federal, state or foreign regulatory review to which we may become subject, regardless of the outcome, would be costly and time-consuming.

​

For example, to enforce compliance with the federal laws, the U.S. Department of Justice, or DOJ, has recently increased its scrutiny of interactions between healthcare companies and healthcare providers, which has led to a number of investigations, prosecutions, convictions and settlements in the healthcare industry. Dealing with investigations can be time and resource consuming and can divert management's attention from our core business. Additionally, if we settle an investigation with law enforcement or other regulatory agencies, we may be forced to agree to additional onerous compliance and reporting requirements as part of a consent decree or corporate integrity agreement. Any such investigation or settlement could increase our costs or otherwise have an adverse effect on our business.

​

We may be liable if the FDA or another regulatory agency concludes that we have engaged in the off-label promotion of our products.

​

Our promotional materials and training methods must comply with FDA and other applicable laws and regulations, including the prohibition of the promotion of the off-label use of our products. Healthcare providers may use our products off-label, as the FDA does not restrict or regulate a physician's choice of treatment within the practice of medicine. However, if the FDA determines that our promotional materials or training constitute promotion of an off-label use, it could request that we modify our training or promotional materials or subject us to regulatory or enforcement actions, including the issuance of an untitled letter, a warning letter, injunction, seizure, civil fine and criminal penalties. It is also possible that other federal, state or foreign enforcement authorities might take action if they consider our promotional or training materials to constitute promotion of an unapproved use, which could result in significant fines or penalties. Although we intend to train our marketing and direct sales force to not promote our products for uses outside of their cleared uses and our policy will be to refrain from statements that could be considered off-label promotion of our products, the FDA or another regulatory agency could disagree and conclude that we have engaged in off-label promotion. In addition, the off-label use of our products may increase the risk of product liability claims. Product liability claims are expensive to defend and could result in substantial damage awards against us and harm our reputation.

​

International sales of medical devices are subject to foreign government regulations, which vary substantially from country to country. In order to market our products in other countries, we must obtain regulatory approvals and comply with extensive safety and quality regulations in other countries.

​

In the EEA, our devices are required to comply with the essential requirements set out in Annex I of the EU Active Implantable Medical Device Directive (Council Directive 90/385/EEC) in order to be placed on the market. Provided that our devices successfully complete a conformity assessment under Council Directive 90/385/EEC demonstrating compliance with these essential requirements, we may affix the CE conformity mark to our devices, without which they cannot be commercialized in the EEA.

​

The advertising and promotion of our products is subject to the laws of EEA Member States implementing Directive 2006/114/EC concerning misleading and comparative advertising, Directive 2005/29/EC on unfair commercial practices, as well as other EEA Member State laws or codes of practice governing the advertising and promotion of medical devices. These laws may limit or restrict the advertising and promotion of our products to the general public and may impose limitations on our promotional activities with healthcare providers, which could negatively impact our business, operating results and financial condition.

​

Off-label use of our product by patients could lead to product liability claims and regulatory action.

​

Eversense is currently labeled as non-adjunctive; however twice daily fingerstick calibrations are still required. We have no control over whether patients adhere to labeling instructions and confirm blood glucose levels to ensure calibration with Eversense. If a patient fails to do so and has an adverse reaction to self-medication, the patient might make a claim against us. While we do not believe that, as a general matter, such a claim would have merit, the possibility of an adverse result to the manufacturer cannot be dismissed, and in any event we could incur significant defense costs. Also, if there should be widespread off-label use of our system by patients, and resulting adverse medical events, the FDA or other regulatory bodies might require us, to implement additional measures to reduce off-label use, which could be costly or reduce adoption of Eversense.

​

Legislative or regulatory healthcare reforms may make it more difficult and costly for us to obtain regulatory clearance or approval of our products.

​

Recent political, economic and regulatory influences are subjecting the healthcare industry to fundamental changes. The sales of our products depend in part on the availability of coverage and reimbursement from third-party payors such as government health administration authorities, private health insurers, health maintenance organizations and other healthcare-related organizations. Both the federal and state governments in the United States continue to propose and pass new legislation and regulations designed to contain or reduce the cost of healthcare. This legislation and regulation may result in decreased reimbursement for medical devices, which may further exacerbate industry-wide pressure to reduce the prices charged for medical devices. This could harm our ability to market our products and generate sales.

​

On a global level, the regulatory environment is increasingly stringent and unpredictable. Many countries have introduced or expanded their existing regulation of medical devices or are planning to expand their existing regulation in the future. Regulatory requirements continue to differ significantly among countries. We expect this global regulatory environment will continue to evolve, which could impact the cost, the time needed to approve, and ultimately, our ability to maintain existing approvals or obtain future approvals for our products. For example, in the EU, the EU Medical Device Regulation will repeal and replace both Directive 93/42/EEC concerning medical devices and Directive 90/385/EEC concerning active implantable medical devices, and therefore will materially change the regulatory environment in which we operate in Europe. The majority of the provisions in the EU Medical Device Regulation apply from spring 2020. The Company will need to ensure compliance with the EU Medical Device Regulation in the future if it is to place a medical device on the EU market after this regulation comes into force and this may take time and require additional resources to ensure compliance.

​

Regulations of the FDA and other regulatory agencies in and outside the U.S. impose extensive compliance and monitoring obligations on our business. These agencies review our design and manufacturing practices, labeling, record keeping, manufacturers’ required reports of adverse experiences and other information to identify potential problems with marketed medical devices. We are subject to unannounced device inspections by European Notified Bodies, as well as other regulatory agencies overseeing the implementation and adherence of applicable regulations. These inspections may include our suppliers’ facilities. In addition, EU member states have powers to suspend the marketing and use, or demand the recall, of unsafe or non-compliant devices. They also have the power to bring enforcement action against companies or individuals for breaches of the device rules. Non-compliance may also result in Notified Bodies revoking any certificate of conformity that they have issued for a device or the manufacturer’s quality system.

​

In addition, FDA regulations and guidance are often revised or reinterpreted by the FDA in ways that may significantly affect our business and our products. Any new regulations or revisions or reinterpretations of existing regulations may impose additional costs or lengthen review times of our products. Delays in receipt of or failure to receive regulatory clearances or approvals for our products would harm our business, financial condition and operating results.

​

While a goal of healthcare reform is to expand coverage to more individuals, it also involves increased government price controls, additional regulatory mandates and other measures designed to constrain medical costs. For example, the PPACA was enacted in March 2010. The PPACA substantially changes the way healthcare is financed by both governmental and private insurers, encourages improvements in the quality of healthcare items and services and significantly impacts the medical device industries. Among other things, the PPACA:

​

​

Table of Contents

There have been executive, judicial and Congressional challenges to certain aspects of the PPACA. While Congress has not passed comprehensive repeal legislation, it has enacted laws that modify certain provisions of the PPACA such as removing penalties, starting January 1, 2019, for not complying with the PPACA’s individual mandate to carry health insurance and delaying the implementation of certain PPACA-mandated fees. Additionally, the 2020 federal spending package permanently eliminated, effective January 1, 2020, the PPACA-mandated medical device tax and “Cadillac” tax on high-cost employer-sponsored health coverage and, effective January 1, 2021, also eliminated the health insurer tax. On December 14, 2018, a Texas U.S. District Court Judge ruled that the PPACA is unconstitutional in its entirety because the “individual mandate” was repealed by Congress as part of the Tax Cuts and Jobs Act of 2017. Additionally, on December 18, 2019, the U.S. Court of Appeals for the 5th Circuit upheld the District Court ruling that the individual mandate was unconstitutional and remanded the case back to the District Court to determine whether the remaining provisions of the PPACA are invalid as well. The U.S. Supreme Court is currently reviewing the case, although it is unknown when a decision will be made. Further, although the U.S. Supreme Court has not yet ruled on the constitutionality of the PPACA, on January 28, 2021, President Biden issued an executive order to initiate a special enrollment period from February 15, 2021 through May 15, 2021 for purposes of obtaining health insurance coverage through the PPACA marketplace. The executive order also instructs certain governmental agencies to review and reconsider their existing policies and rules that limit access to healthcare, including among others, reexamining Medicaid demonstration projects and waiver programs that include work requirements, and policies that create unnecessary barriers to obtaining access to health insurance coverage through Medicaid or the PPACA. It is unclear how the Supreme Court ruling, other such litigation, and the healthcare reform measures of the Biden administration will impact the PPACA and our business.

​

In addition, other legislative changes have been proposed and adopted since the PPACA was enacted. On August 2, 2011, the Budget Control Act of 2011 was signed into law, which, among other things, includes reductions to Medicare payments to providers of 2% per fiscal year, which went into effect on April 1, 2013 and, due to subsequent legislative amendments to the statute, will remain in effect through 2030 with the exception of a temporary suspension from May 1, 2020 through March 31, 2021 unless additional Congressional action is taken. On January 2, 2013, the American Taxpayer Relief Act of 2012 was signed into law, which, among other things, reduced Medicare payments to several providers, including hospitals, and increased the statute of limitations period for the government to recover overpayments to providers from three to five years.

​

At this time, we cannot predict which, if any, additional healthcare reform proposals will be adopted, when they may be adopted or what impact they, or the PPACA, may have on our business and operations, and any of these impacts may be adverse on our operating results and financial condition.

Risks Related to our Common Stock

​

Because our stock price has and will likely continue to be highly volatile, the market price of our common stock may be lower or more volatile than expected.

​

Our stock price has been highly volatile. The stock market in general and the market for innovative, emerging medtech and biotechnology companies in particular have experienced extreme volatility that has often been unrelated to the operating performance of particular companies. From December 23, 2020 through March 3, 2021, the trading price of our common stock has been as low as $0.43 per share and as high as $5.56 per share. This recent extreme stock price volatility has been accompanied by extremely high trading volume in our common stock in comparison to historical experience. During this period, the average daily trading volume of our common stock has been approximately 65 million shares and on January 19, 2021, our trading volume exceeded 409 million shares, whereas the average daily trading volume from January 1, 2020 to December 22, 2020 was 2.4 million shares.

​

The extreme recent increase in trading volume and volatility has not necessarily correlated to the company’s announcement of material developments and appears unrelated to changes in actual or expected operating performance. Purchases or sales of large quantities of our stock, including the establishment and/or closing of significant short positions in our stock could have an unusual or adverse effect on our market price. Market fluctuations may also cause short sellers to periodically enter the market in the belief that we will have poor results in the future. Abnormal trading

58

Table of Contents

activity, including activity that is considered market manipulation, can lead to irrational and/or temporary movements in the price of our common stock, which, in turn, may increase its risk and volatility. We cannot predict the actions of market participants and, therefore, can offer no assurances that the market for our common stock will be stable or appreciate over time.

​

The market price of our common stock may also be influenced by many additional factors, including:

​

​

The issuance of additional stock in connection with financings, acquisitions, investments, our equity incentive plans, or otherwise will dilute our existing stockholders.

​

Our certificate of incorporation authorizes us to issue up to 900,000,000 shares of common stock and up to 5,000,000 shares of preferred stock with such rights and preferences as may be determined by our board of directors. Subject to compliance with applicable rules and regulations, we may issue our shares of common stock, including securities convertible into common stock, in connection with a financing, acquisition, investment, our equity incentive plans or otherwise. Any such issuance could result in substantial dilution to our existing stockholders and cause the trading price of our common stock to decline.

​

The holders of the convertible preferred stock rank senior to our common stock upon a liquidation of our company.

​

In the event of a liquidation, dissolution or winding up of our company, our Series A convertible preferred stock, along with any convertible preferred stock that we may issue to PHC or Energy Capital, will rank senior to our common stock. Each share of preferred stock will be entitled to receive an amount per share equal to the greater of the purchase price paid and the amount that the holder would have been entitled to receive at such time if the convertible preferred stock were converted into common stock.

​

Until the holders of the convertible preferred stock have been paid their liquidation amount in full, no payment will be made to any holder of common stock. If our assets, or the proceeds from their sale, distributable among the holders of the convertible preferred stock are not sufficient to pay the liquidation amount in full, then those assets or proceeds will be distributed among the holders of the convertible preferred stock. In that case, there would be no assets or proceeds remaining to be distributed to holders of our common stock, which could impact the trading price of our common stock.

​

59

Table of Contents

Shares of our convertible preferred stock, including shares issuable under our Equity Line Agreement with Energy Capital, and the PHC Notes are convertible into shares of our common stock and, upon conversion, will dilute your percentage of ownership.

​

Each share of our convertible preferred stock is convertible at any time at the option of the holder into approximately 2,100 shares of our common stock (subject to customary anti-dilution adjustments, including in the event of any stock split). Under the Equity Line Agreement, subject to the satisfaction of certain conditions, including that we have less than $8 million of cash, cash equivalents and other available credit (aside from availability under the Equity Line Agreement), we also have the right, in our sole discretion, to present Energy Capital with a purchase notice directing Energy Capital (as principal) to purchase shares of Series B Preferred Stock at a price of $1,000 per share (not to exceed $4.0 million worth of shares) once per month, up to an aggregate of $12.0 million of our Series B Preferred Stock, with such shares convertible into common stock at a price of $0.3951 per share. Also, under the Equity Line Agreement, beginning January 1, 2022, subject to the satisfaction of certain conditions, Energy Capital has the option to purchase any Series B Preferred Stock that we have not already sold to it under the agreement at a price of $1,000 per share.

The PHC Notes are also convertible into our common stock at the option of the holder. Accordingly, any conversion of convertible preferred stock or the PHC Notes would dilute the ownership of our holders of common stock. The potential dilutive effect of the conversion of shares of convertible preferred stock or convertible notes may also adversely affect our ability to obtain additional financing on favorable terms or at all.

​

Holders of the convertible preferred stock and convertible notes have the ability exert substantial influence over us in a manner adverse to your interests.

​

Subject to maintaining specified ownership thresholds, the holders of convertible preferred stock and the PHC Notes have the ability to designate, in the aggregate, up to three members of our board of directors.

​

The holders of convertible preferred stock generally are entitled to vote with the holders of the shares of common stock on all matters submitted for a vote of holders of shares of common stock (voting together with the holders of shares of common stock as one class) on an as-converted basis. Additionally, certain matters require the approval of the majority of the outstanding convertible preferred stock, voting as a separate class, including (i) altering or changing adversely the powers, privileges, preferences or rights of the convertible preferred stock, or (ii) amendments, modifications, repeal or waiver of any provision of our certificate of incorporation or of the certificate of designations that would adversely affect the rights, preferences, privileges or powers of the convertible preferred stock.

​

As a result, the holders of our convertible preferred stock and the PHC Notes are able to influence our decisions, including the election and removal of directors, any merger, consolidation, sale of all or substantially all of our assets, or other significant corporate transactions. Some of these persons or entities may have interests different the interests of the holders of our common stock.

​

The future funding pursuant to agreements to sell convertible preferred stock to PHC and Energy Capital is not guaranteed.

​

We have entered into agreements with PHC and Energy Capital that, collectively, provide for our receipt of up to $27 million of aggregate funding pursuant to the sale of convertible preferred stock to PHC and Energy Capital. Pursuant to our agreement with PHC, we have the option to sell and issue to PHC up to $15.0 million of convertible preferred stock on or before December 31, 2022, contingent upon our obtaining FDA approval for the 180-day Eversense product for marketing in the United States before such date. On November 9, 2020, we entered into the Equity Line Agreement with Energy Capital. Under the Equity Line Agreement, subject to the satisfaction of certain conditions, including that we have less than $8 million of cash, cash equivalents and other available credit (aside from availability under the Equity Line Agreement), we have the right, in our sole discretion, to present Energy Capital with a purchase notice directing Energy Capital (as principal) to purchase shares of Series B Preferred Stock at a price of $1,000 per share (not to exceed $4.0 million worth of shares) once per month, up to an aggregate of $12.0 million of our Series B Preferred Stock, with such shares convertible into common stock at a price of $0.3951 per share. Also, under the Equity Line Agreement, beginning January 1, 2022, subject to the satisfaction of certain conditions, Energy Capital has the

60

Table of Contents

option to purchase any Series B Preferred Stock that we have not already sold to it under the agreement at a price of $1,000 per share. Because of the contingencies of each transaction, there can be no guarantee that we will be able to sell the additional convertible preferred stock to PHC or Energy Capital. If we are unable to do so, we may be forced to seek to raise additional capital on less advantageous terms, if available at all, which would likely have a material adverse effect on our liquidity and the trading price of our common stock.

​

We may not be entitled to forgiveness of our recently received PPP Loan, and our application for the PPP Loan could in the future be determined to have been impermissible or could result in damage to our reputation.

​

On April 22, 2020 we received proceeds of $5.8 million from a loan under the Paycheck Protection Program of the CARES Act, a portion of which may be forgiven, which used to retain current employees, maintain payroll and make lease and utility payments. The PPP Loan matures on April 21, 2022 and bears annual interest at a rate of 1.0%. Under the CARES Act, loan forgiveness is available for the sum of documented payroll costs, covered rent payments, covered mortgage interest and covered utilities during the eight-week period beginning on the date of loan approval. Not more than 25% of the forgiven amount may be for non-payroll costs. The amount of the PPP Loan eligible to be forgiven is limited because of certain headcount reductions that we implemented in March 2020 and will be reduced if our full-time headcount declines further, or if salaries and wages for employees with salaries of $100,000 or less annually are reduced by more than 25%. We will be required to repay any portion of the outstanding principal that is not forgiven, along with accrued interest and we cannot provide any assurance that we will be eligible for loan forgiveness, or that any amount of the PPP Loan will ultimately be forgiven by the SBA. We expect to apply forgiveness and make payments on any unforgiven portion on the PPP Loan in the second half of 2021. Furthermore, on April 28, 2020, the Secretary of the U.S. Department of the Treasury stated that the SBA will perform a full review of any PPP loan over $2.0 million before forgiving the loan.

​

In order to apply for the PPP Loan, we were required to certify, among other things, that the current economic uncertainty made the PPP Loan request necessary to support our ongoing operations. We made this certification in good faith after analyzing, among other things, our financial situation and access to alternative forms of capital, and believe that we satisfied all eligibility criteria for the PPP Loan, and that our receipt of the PPP Loan is consistent with the broad objectives of the Paycheck Protection Program of the CARES Act. The certification described above does not contain any objective criteria and is subject to interpretation. On April 23, 2020, the SBA issued guidance stating that it is unlikely that a public company with substantial market value and access to capital markets will be able to make the required certification in good faith. Subsequently, on April 29, 2020 the SBA issued guidance that it will review all PPP loans of more than $2 million, following the lender’s submission of the borrower’s loan forgiveness application. The lack of clarity regarding loan eligibility under the Paycheck Protection Program has resulted in significant media coverage and controversy with respect to public companies applying for and receiving loans. If, despite our good-faith belief that given our Company's circumstances we satisfied all eligible requirements for the PPP Loan, we are later determined to have violated any of the laws or governmental regulations that apply to us in connection with the PPP Loan, such as the False Claims Act, or it is otherwise determined that we were ineligible to receive the PPP Loan, we may be subject to penalties, including significant civil, criminal and administrative penalties and could be required to repay the PPP Loan in its entirety. In addition, receipt of a PPP Loan may result in adverse publicity and damage to reputation, and a review or audit by the SBA or other government entity or claims under the False Claims Act could consume significant financial and management resources. Should we be audited or reviewed by federal or state regulatory authorities as a result of filing an application for forgiveness of the PPP Loan or otherwise, such audit or review could result in the diversion of management’s time and attention and legal and reputational costs. If we were to be audited or reviewed and receive an adverse determination or finding in such audit or review, we could be required to return the full amount of the PPP Loan. Any of these events could have a material adverse effect on our business, results of operations and financial condition.

Our GAAP operating results could fluctuate substantially due to changes in fair value of the liability options and the derivatives related to the embedded conversion option, interest make-whole provision and make-whole fundamental change provision features of the notes.

Our liability options related to the Energy Capital Agreement and Masters Capital Agreement are classified as liabilities in accordance with ASC 480 on the Company’s balance sheet and are recorded at fair value. These options are

61

Table of Contents

required to be remeasured to fair value at each reporting period with the change recorded in change in fair value of derivatives that is a component of other income (expense).

​

Our convertible senior subordinated notes contain certain embedded features that require bifurcation of the embedded conversion option along with the fundamental change make-whole provision, interest make-whole provision, and the cash settled fundamental make-whole shares provision, and recorded the fair value of these embedded features as a derivative liability in the Company’s consolidated balance sheets in accordance with Accounting Standards Codification, or ASC, Topic 815, Derivatives and Hedging.

​

ASC 815 requires companies to bifurcate certain embedded derivatives from their host instruments and account for them as free standing derivative financial instruments according to certain criteria. The fair value of the derivative is remeasured to fair value at each balance sheet date, with a resulting non-cash gain or loss related to the change in the fair value of the derivative being charged to earnings (loss). We utilize a third-party valuation expert and the binomial option pricing method to determine the fair value of the derivative instruments at each reporting date using inputs based on recent trading prices (Level 2) and other observable inputs, including our common stock price, implied volatility, interest rates and credit spreads, or unobservable inputs (Level 3) where there is an absence of recent trading prices.

​

We cannot predict the effect that the accounting for the options and notes and the associated fluctuations in the fair value of the liability options and embedded features of the notes will have on our future GAAP financial results, the trading of our common stock and the trading price of the notes, which could be material. Continued extreme volatility in our stock price, as we have experienced recently, could exacerbate such effects.

​

If our estimates relating to our critical accounting policies are based on assumptions or judgments that change or prove to be incorrect, our operating results could fall below expectations of financial analysts and investors, resulting in a decline in our stock price.

​

The preparation of financial statements in conformity with U.S. GAAP requires our management to make estimates, assumptions and judgments that affect the amounts reported in the consolidated financial statements and accompanying notes. We base our estimates on historical experience and on various other assumptions that we believe to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets, liabilities, equity, revenue and expenses that are not readily apparent from other sources. Our operating results may be adversely affected if our assumptions change or if actual circumstances differ from those in our assumptions, which could cause our operating results to fall below the expectations of financial analysts and investors, resulting in a decline in our stock price. Significant assumptions and estimates used in preparing our consolidated financial statements include those related to revenue recognition and variable consideration, reserves for inventory obsolescence and warranties, stock-based compensation, embedded features of our senior convertible notes and income taxes.

​

We do not intend to pay cash dividends in the foreseeable future.

​

We have never declared or paid cash dividends on our capital stock. We currently intend to retain all available funds and any future earnings for use in the operation and expansion of our business and do not anticipate paying any cash dividends in the foreseeable future. In addition, pursuant to our debt agreements, we are precluded from paying any cash dividends. Accordingly, you may have to sell some or all of your shares of our common stock in order to generate cash flow from your investment. You may not receive a gain on your investment when you sell shares and you may lose the entire amount of the investment.

​

Provisions in our corporate charter documents and under Delaware law may prevent or frustrate attempts by our stockholders to change our management and hinder efforts to acquire a controlling interest in us, and the market price of our common stock may be lower as a result.

​

There are provisions in our certificate of incorporation and bylaws that may make it difficult for a third party to acquire, or attempt to acquire, control of our company, even if a change of control was considered favorable by some or

62

Table of Contents

all of our stockholders. For example, our board of directors has the authority to issue up to 5,000,000 shares of preferred stock. The board of directors can fix the price, rights, preferences, privileges, and restrictions of the preferred stock without any further vote or action by our stockholders. The issuance of shares of preferred stock may delay or prevent a change of control transaction. As a result, the market price of our common stock and the voting and other rights of our stockholders may be adversely affected. An issuance of shares of preferred stock may result in the loss of voting control to other stockholders.

​

Our charter documents also contain other provisions that could have an anti-takeover effect, including:

​

​

In addition, we are subject to the anti-takeover provisions of Section 203 of the Delaware General Corporation Law, which regulates corporate acquisitions by prohibiting Delaware corporations from engaging in specified business combinations with particular stockholders of those companies. These provisions could discourage potential acquisition proposals and could delay or prevent a change of control transaction. They could also have the effect of discouraging others from making tender offers for our common stock, including transactions that may be in your best interests. These provisions may also prevent changes in our management or limit the price that investors are willing to pay for our stock.

Our amended and restated certificate of incorporation and amended and restated bylaws provide that the Court of Chancery of the State of Delaware and the federal district courts of the United States of America will be the exclusive forums for substantially all disputes between us and our stockholders, which could limit our stockholders' ability to obtain a favorable judicial forum for disputes with us or our directors, officers or employees.

​

Our amended and restated certificate of incorporation provides that the Court of Chancery of the State of Delaware is the exclusive forum for the following types of actions or proceedings under Delaware statutory or common law: (i) any derivative action or proceeding brought on our behalf, (ii) any action asserting a claim for breach of a fiduciary duty owed by any of our directors, officers or other employees to us or our stockholders, (iii) any action asserting a claim arising pursuant to any provision of the Delaware General Corporation Law, our amended and restated certificate of incorporation or our amended and restated bylaws or (iv) any action asserting a claim governed by the internal affairs doctrine. However, this exclusive forum provision would not apply to suits brought to enforce a duty or liability created by the Securities Act or the Exchange Act.

​

Our amended and restated bylaws further provide that the federal district courts of the United States of America will be the exclusive forum for resolving any complaint asserting a cause of action arising under the Securities Act. We note that investors cannot waive compliance with the federal securities laws and the rules and regulations thereunder.

​

These 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 our directors, officers or other employees, which may discourage lawsuits against us and our directors, officers and other employees. Any person or entity purchasing or otherwise acquiring any interest in any of our securities shall be deemed to have notice of and consented to these provisions. There is uncertainty as to whether a court would enforce such provisions, and the enforceability of similar choice of forum provisions in other companies’ charter documents has been challenged in legal proceedings. While the Delaware courts have determined that such choice of forum provisions are facially valid, a stockholder may nevertheless seek to bring a claim in a venue other than those designated in the exclusive forum provisions, and there can be no assurance that such provisions will be enforced by a court in those other jurisdictions. If a court were to find these types of provisions to be inapplicable or unenforceable, and if a court were to find the exclusive forum provision in our amended and restated bylaws to be

63

Table of Contents

inapplicable or unenforceable in an action, we may incur additional costs associated with resolving the dispute in other jurisdictions, which could materially adversely affect our business.

If we fail to maintain proper and effective internal controls, our ability to produce accurate financial statements on a timely basis could be impaired.

​

We are subject to the reporting requirements of the Securities Exchange Act of 1934, as amended, the Sarbanes-Oxley Act of 2002, the Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010 and the rules and regulations of the NYSE American. The Sarbanes-Oxley Act requires, among other things, that we maintain effective disclosure controls and procedures and internal control over financial reporting and perform system and process evaluation and testing of our internal control over financial reporting to allow management to report on the effectiveness of our internal control over financial reporting. This requires that we incur substantial additional professional fees and internal costs to expand our accounting and finance functions and that we expend significant management efforts.

​

During the evaluation and testing process of our internal controls, if we identify one or more material weaknesses in our internal control over financial reporting that exists at the reporting date, we will be unable to assert that our internal control over financial reporting is effective. We have no material weaknesses in our internal control over financial reporting at December 31, 2020. While we have established certain procedures and controls over our financial reporting processes, we cannot assure you that these efforts will prevent future material weaknesses or restatements of our financial statements. For future reporting periods, our independent registered public accounting firm may issue a report that is adverse in the event it is not satisfied with the level at which our controls are documented, designed or operating. We may not be able to remediate any future material weaknesses, or to complete our evaluation, testing and any required remediation in a timely fashion.

​

Any failure to maintain effective internal control over financial reporting could severely inhibit our ability to accurately report our financial condition or results of operations. If we are unable to conclude that our internal control over financial reporting is effective, or if our independent registered public accounting firm determines we have a material weakness or significant deficiency in our internal control over financial reporting, we could lose investor confidence in the accuracy and completeness of our financial reports, the market price of our common stock could decline, and we could be subject to sanctions or investigations by the NYSE American, the SEC or other regulatory authorities. 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 capital markets.

​

If securities or industry analysts do not publish research or reports, or publish unfavorable research or reports, about us, our business or our market, our stock price and trading volume could decline.

​

The trading market for our common stock is influenced by the research and reports that securities or industry analysts publish about us or our business, our market and our competitors. Securities or industry analysts may elect not to initiate or continue to provide coverage of our common stock, and such lack of coverage may adversely affect the market price of our common stock. Even if we have securities or industry analyst coverage, we will not have any control over the analysts, or the content and opinions included in their reports. The price of our stock could decline if one or more securities or industry analysts downgrade our stock or issue other unfavorable commentary or research. If one or more securities or industry analysts ceases coverage of our company or fails to publish reports on us regularly, demand for our stock could decrease, which in turn could cause our stock price or trading volume to decline.

​

Our effective tax rate may fluctuate, and we may incur obligations in tax jurisdictions in excess of accrued amounts.

​

We are subject to taxation in numerous U.S. states and territories. As a result, our effective tax rate is derived from a combination of applicable tax rates in the various places that we operate. In preparing our financial statements, we estimate the amount of tax that will become payable in each of such places. Nevertheless, our effective tax rate may be different than experienced in the past due to numerous factors, including passage of the newly enacted federal income tax law, changes in the mix of our profitability from state to state, the results of examinations and audits of our tax filings, our inability to secure or sustain acceptable agreements with tax authorities, changes in accounting for income

64

Table of Contents

taxes and changes in tax laws. Any of these factors could cause us to experience an effective tax rate significantly different from previous periods or our current expectations and may result in tax obligations in excess of amounts accrued in our financial statements.

​

We may be unable to utilize our federal net operating loss carryforwards to reduce our income taxes.

​

At December 31, 2020, we had federal and state net operating loss, or NOL, carryforwards of $515.24 million and had research and experimental credit carryforwards of $12.76 million. NOL carryforwards in the amount of $198.7 million will expire in varying amounts between 2021 and 2037. These net operating loss carryforwards could expire unused and be unavailable to offset future income tax liabilities. Under the Tax Cuts and Jobs Act of 2017, as modified by the CARES Act, federal NOL carryforwards generated in tax years beginning after December 31, 2017 may be carried forward indefinitely, but in the case of tax years beginning after 2020, may only be used to offset 80% of our taxable income annually. Federal NOL carryforwards generated in taxable years beginning in 2018, 2019 and 2020 will similarly carry forward indefinitely but will not be subject to such 80% of annual taxable income limitation. In addition, under Section 382 of the Internal Revenue Code of 1986, as amended, or the Code, and corresponding provisions of state law, if a corporation undergoes an "ownership change," which generally occurs if the percentage of the corporation's stock owned by 5% stockholders increases by more than 50% over a three-year period, the corporation's ability to use its pre-change NOL carryforwards and other pre-change tax attributes to offset its post-change income may be limited. We have not determined if we have experienced Section 382 ownership changes in the past and if a portion of our NOL and tax credit carryforwards are subject to an annual limitation under Section 382. In addition, we may experience ownership changes in the future as a result of subsequent shifts in our stock ownership, some of which may be outside of our control. If we determine that an ownership change has occurred and our ability to use our historical NOL and tax credit carryforwards is materially limited, it would harm our future operating results by effectively increasing our future tax obligations.

Overview

​

We are a medical technology company focused on the development and commercialization of a long-term, implantable continuous glucose monitoring, or CGM, system to improve the lives of people with diabetes by enhancing their ability to manage their disease with relative ease and accuracy. Our Eversense and Eversense XL CGM systems are designed to continually and accurately measure glucose levels in people with diabetes via an under-the-skin sensor, a removable and rechargeable smart transmitter, and a convenient app for real-time diabetes monitoring and management for a period of up to 90 and 180 days, respectively, as compared to seven to 14 days for non-implantable CGM systems. The original Eversense CGM system received a CE mark in June 2016, which marked the first approval for the product to be sold within the European Economic Area. Subsequently, the extended life Eversense XL CGM system received its CE mark in September 2017 and is currently available in select markets in Europe, the Middle East, and Africa, or EMEA. In June 2018, the U.S. Food and Drug Administration, or FDA, approved the Eversense CGM system and it is currently available throughout the United States. In June 2019, we received FDA approval for the non-adjunctive indication (dosing claim) for the Eversense system. With this approval and the availability of a new app in December 2019, the Eversense system can now be used as a therapeutic CGM in the United States to replace fingerstick blood glucose measurement to make treatment decisions, including insulin dosing.

​

Our net revenues are derived from sales of the Eversense system which is sold in two separate kits: the disposable Eversense Sensor Pack which includes the sensor, insertion tool, and adhesive patches, and the durable Eversense Smart Transmitter Pack which includes the transmitter and charger.

​

We sell directly to our network of distributors and strategic fulfillment partners, who provide the Eversense system to healthcare providers and patients through a prescribed request and invoice insurance payors for reimbursement. Sales of the Eversense system are widely dependent on the ability of patients to obtain coverage and adequate reimbursement from third-party payors or government agencies. We leverage and target regions where we have coverage decisions for patient device use and provider insertion and removal procedure payment. During 2020, we received positive payor coverage decisions from Cigna Corporation, who has more than 17 million medical customers and offers a Medicare Advantage plan in 17 states and Washington, DC, Blue Cross and Blue Shield plans, and announced local coverage determinations, or LCD, proposals for implantable therapeutic CGMs such as Eversense by all the Medicare Administrative Contractors to enable Eversense to be used by Medicare beneficiaries as a Part B physician service. We continue to see momentum of broad national payor acceptance, including on August 3, 2020, the Center for Medicare and Medicaid Services, or CMS, released its Calendar Year 2021 Medicare Physician Fee Schedule Proposed Rule that announces proposed policy changes for Medicare payments, including the proposed establishment of national payment amounts for the three CPT© Category III codes describing the insertion (CPT 0446T), removal (0447T), and removal and insertion (0048T) of an implantable interstitial glucose sensor, which describes our Eversense CGM systems, as a medical benefit, rather than as part of the Durable Medical Equipment channel that includes other CGMs.

​

We are in the early commercialization stages of the Eversense brand and are focused on driving awareness of our CGM system amongst intensively managed patients and their healthcare providers. In both the United States and our overseas markets, we entered into a strategic partnerships and distribution agreements that allow third party collaborators with direct sales forces and established distribution systems to market and promote Senseonics CGM systems, including Eversense, Eversense XL and future generation products.

​

​

United States Development and Commercialization of Eversense

​

In 2016, we completed our PRECISE II pivotal clinical trial in the United States. This trial, which was fully enrolled with 90 subjects, was conducted at eight sites in the United States. In the trial, we measured the accuracy of Eversense measurements through 90 days after insertion. We also assessed safety through 90 days after insertion or through sensor removal. In the trial, we observed a mean absolute relative difference, or MARD, of 8.5% utilizing two calibration points for Eversense across the 40-400 mg/dL range when compared to YSI blood reference values during the 90-day continuous wear period. Based on the data from this trial, in October 2016 we submitted a pre-market approval, or PMA, application to the FDA to market Eversense in the United States for 90-day use. On June 21, 2018, we received PMA approval from the FDA for the Eversense system. In July 2018, we began distributing the Eversense system

68

Table of Contents

directly in the United States through our own direct sales and marketing organization. We have received Category III CPT codes for the insertion and removal of the Eversense sensor.

​

In December 2018, we initiated the PROMISE pivotal clinical trial to evaluate the safety and accuracy of Eversense for a period of up to 180 days in the United States. In September 30, 2019, we completed enrollment of the PROMISE trial. In the trial, we observed performance matching that of the current Eversense 90-day product available in the United States, with a mean absolute relative difference, or MARD, of 8.5%-9.6%. This result was achieved with reduced calibration, down to one per day, while also doubling the sensor life to 180 days. Following the results of the PROMISE trial, on September 30, 2020, a Premarket Approval, or PMA, supplement application to extend the wearable life of the Eversense CGM System to 180 days was submitted to the FDA.

​

In March 2019, we launched a patient access program, the Eversense Bridge Program, to assist those patients who do not have insurance coverage for Eversense, or whose insurance is denied or insufficient. Pursuant to this program, we provided financial assistance to eligible patients purchasing Eversense, which may have been substantial depending on a patient’s insurance coverage. We also assisted patients in their appeal of adverse coverage decisions made by insurance providers. In December 2020, we terminated the Eversense Bridge Program. We expect our partner Ascensia to implement a patient assistance program and related programs as part of its commercialization efforts. The lack of a patient assistance program, or a program’s design being ineffective, could adversely impact the sales of Eversense and, consequently our net revenues. In addition, we may not be able to recognize a substantial portion of the revenue related to Eversense insertions for the patients participating in these access programs, or previously the Bridge Program. The amount of time required to obtain favorable coverage and reimbursement decisions, including navigating the appeals process with third-party payors, is uncertain, and we may see increased product utilization without corresponding recognized revenue. Our operating results may be adversely impacted if we are unable to obtain successful appeals or favorable coverage decisions by insurance providers, or if there are not effective patient access programs in place.

​

In June 2019, we received FDA approval for the non-adjunctive indication (dosing claim) for the Eversense system and launched with an updated app in December 2019. With this approval, the Eversense system can be used as a therapeutic CGM to replace fingerstick blood glucose measurement for treatment decisions, including insulin dosing.

​

On February 26, 2020, we announced that the FDA approved a subgroup of PROMISE trial participants to continue for a total of 365 days to gather feasibility data on the safety and accuracy of a 365-day sensor. This sub-set of 30 participants were left undisturbed for 365 days with the goal of measuring accuracy and longevity over the full 365 days. Following information gathered from this sub-set and continued development efforts, and pending developments at the FDA relating to the ongoing the ongoing COVID-19 pandemic, in the second half of 2021 we plan to seek Investigational Device Exemption, or IDE, from the FDA to explore the 365-day sensor in a clinical trial. If the IDE is approved in a timely manner, we would target to begin enrollment of a clinical trial, in which we intend to include a pediatric population, in the first half of 2022.

​

In April 2020, we announced that we received regulatory approval in Europe such that the Eversense XL is no longer contraindicated for MRI, which means the sensor does not need to be removed from under the skin during MRI scanning. We had previously obtained this indication for Eversense in the United States in 2019. This MRI approval is a first for the CGM category, as all other sensors are required to be removed during an MRI scan.

​

On August 9, 2020, we entered into a collaboration and commercialization agreement with Ascensia pursuant to which we granted Ascensia the exclusive right to distribute our 90-day Eversense continuous glucose monitoring system and our 180-day Eversense continuous glucose monitoring system worldwide for people with diabetes, with the following initial exceptions: (i) until January 31, 2021, the territory did not include countries covered by our then existing distribution agreement with Roche Diagnostics International AG and Roche Diabetes Care GmbH, which are the Europe, Middle East and Asia, excluding Scandinavia and Israel, and 17 additional countries, including Brazil, Russia, India and China, as well as select markets in the Asia Pacific and Latin American regions; (ii) until September 13, 2021, the territory does not include countries covered by our current distribution agreement with Rubin Medical, which are Sweden, Norway and Denmark; and (iii) until May 31, 2022, the territory does not include Israel. Pursuant to the Commercialization Agreement, in the United States, Ascensia began providing sales support for the 90-day Eversense

Table of Contents

product on October 1, 2020 and the parties have been planning and making arrangements for Ascensia to ramp up sales activities and more fully assume commercial responsibilities in the second quarter of 2021. The Eversense 180-day product is planned to be marketed upon receipt of marketing approval from the FDA. In Germany, Italy and Switzerland, Spain, Poland and the Netherlands, Ascensia assumed commercial responsibilities for Eversense XL beginning on February 1, 2021. For Sweden and Norway, Ascensia will assume commercial responsibilities later this year. Ascensia is entitled to receive a portion of net revenue at specified tiered percentages ranging from the mid-teens to the mid-forty’s based on levels of global net revenues. Ascensia is obligated to achieve specified minimum annual revenue targets and meet specified levels of sales and marketing spend in order to maintain its exclusive distribution rights. Ascensia purchases Eversense and Eversense XL from us at negotiated prices. We remain responsible for product development and manufacturing, including regulatory submissions, approvals and registrations and second level customer support, and Ascensia is responsible for sales, marketing, market access, patient and provider onboarding and first level customer support. We have agreed to establish a joint alliance committee and joint marketing committee, each with equal representation from each party, in order to collaborate.

​

​

European Commercialization of Eversense

​

In September 2017, we received the CE mark for Eversense XL, which is indicated for a sensor life of up to 180 days. Eversense XL began commercialization in Europe in the fourth quarter of 2017. All such commercialization and marketing activities remain subject to applicable government approvals.

​

In May 2016, we entered into a distribution agreement with Roche Diagnostics International AG and Roche Diabetes Care GmbH, together referred to as Roche. Pursuant to the agreement, as amended, we have granted Roche the exclusive right to market, sell and distribute Eversense in the EMEA, excluding Scandinavia and Israel. In addition, Roche has exclusive distribution rights in 17 additional countries, including Brazil, Russia, India and China, as well as select markets in the Asia Pacific and Latin American regions. Roche is obligated to purchase from us specified minimum volumes of Eversense XL CGM components at pre-determined prices. On December 12, 2019, we further amended the distribution agreement to lower minimum volumes for 2020 and increase pricing for the remaining period of the contract. On November 30, 2020 we entered into a final amendment and settlement agreement with Roche to facilitate the transition of distribution to Ascensia as sales conclude on January 31, 2021, including final purchases, and transition support activities. The distribution rights under the agreement expired January 31, 2021, subject to Roche providing certain transition and wind-down services for approximately six months in markets where Ascensia is not initiating distribution.

​

COVID-19

​

On January 30, 2020, the World Health Organization, or the WHO, announced a global health emergency because of a new strain of coronavirus, or COVID-19, and the risks to the international community as the virus spreads globally. On March 11, 2020, the WHO classified the COVID-19 outbreak as a pandemic, based on the rapid increase in exposure globally. In response to the pandemic, many states and jurisdictions have issued stay-at-home orders and other measures aimed at slowing the spread of the coronavirus. The state of Maryland, where we are headquartered, has been affected by COVID-19. The Governor of Maryland issued an order closing all non-essential businesses, which took effect on March 23, 2020. Although the state of Maryland is gradually undergoing a phased reopening plan, substantially all of our workforce is still working from home either all or substantially all of the time. Additionally, because our sensor requires an in-clinic procedure, we saw a reduction in access to clinics and sensor insertions during the initial outbreak.

​

During the latter half of 2020, several new order requests from our distributors led to adjustments to concession allowances previously provided to some of our customers in the United States to reflect actual product usage. While these trends are promising, insertion volumes are still below pre-COVID-19 levels. Additionally, the COVID-19 pandemic infection rates in the United States are still high, vaccine distribution has only just begun, and it is difficult to predict the longevity and severity COVID-19 will have on our business.

​

As a result of the COVID-19 pandemic’s disruption to our operations, suppliers, employees, and the healthcare community in which we sell to and support, and our limited cash resources, in March 2020, we made significant

70

Table of Contents

reductions in our cost structure and operations to improve cash flow and generate future expenditure savings to ensure the long-term success of Eversense. Specifically, in the first quarter of 2020, we temporarily suspended commercial sales and marketing of the Eversense CGM System in the United States to new patients to solely focus our resources on supporting existing users, including ensuring broader insurance coverage for Eversense, and the development and regulatory submission of our new 180-day Eversense product in the United States. In connection with these actions, on March 26, 2020, we reduced our workforce by approximately 60%, over half of which were sales personnel.

​

Critical Accounting Policies and Use of Estimates

​

The discussion and analysis of our financial condition and results of operations are based upon our consolidated financial statements, which have been prepared in accordance with generally accepted accounting principles in the United States.

​

The preparation of our consolidated financial statements requires us to make estimates, assumptions and judgments that affect the reported amounts of assets, liabilities and equity and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting period. These estimates, particularly estimates relating to accounting for variable consideration related to revenue, warranty obligations, inventory obsolescence and embedded derivatives, have a material impact on our financial statements and are discussed in detail throughout our analysis of the results of operations discussed below.

​

We base our estimates on historical experience and various other assumptions that we believe are reasonable under the circumstances, the results of which form the basis for making judgments about the carrying value of assets, liabilities and equity that are not readily apparent from other sources. Actual results and outcomes could differ from these estimates and assumptions.

​

Revenue

​

We generate product revenue from sales of the Eversense system and related components and supplies at a fixed price to third-party distributors in the European Union and to a network of strategic fulfillment partners in the United States, or collectively, Customers, who then resell the products to health care providers and patients. We are paid for our sales directly to the Customers, regardless of whether or not the Customers resell the products to health care providers and patients. Under the terms of our distribution agreement with Roche, Roche was contractually obligated to make certain minimum purchases of Eversense systems from us and, accordingly, the revenue we recognize for any given period is not necessarily indicative of the level of sales to end users for that, or any other, period.

​

Revenue from product sales is recognized at a point in time when the Customers obtain control of our product based upon the delivery terms as defined in the contract at an amount that reflects the consideration which we expect to receive in exchange for the product. Contracts with our distributors contain performance obligations, mostly for the supply of goods, and is typically satisfied upon transfer of control of the product.

​

We recognize revenue only to the extent that it is probable that a significant reversal in the amount of cumulative revenue recognized will not occur in a future period. Our contracts may contain some form of variable consideration such as prompt-pay discounts or tier-volume price discounts. Variable consideration, including reimbursements paid by us to our Customers in accordance with the Eversense Bridge Program initiated in March 2019 and to a lesser extent, other discounts, is treated as a reduction in revenue when the product sale is recognized. Depending on the variable consideration, we develop estimates for the expected value based on the terms of the agreements, historical data, third-party payor mix, reimbursement rates, and market conditions. In connection with the Eversense Bridge Program, we reimburse participating Customers an amount up to a fixed maximum for the difference in the cost of the Eversense System and what they collect from insurance payors and the patient’s fee of $99. Our Customers are responsible for confirming patient insurance coverage, obtaining pre-authorizations, determining eligibility, and continuously provide us with data regarding which patient orders are under the program and which are not. We use this data, along with actual reimbursements that have been validated to patient claims, to support our expected reimbursement estimates. Estimated reimbursement payments for product shipped to our Customers but not provided to a patient within the same reporting period are recorded within accrued expenses and other current liabilities in our accompanying consolidated balance sheets. The Eversense Bridge Program concluded on December 31, 2020, and the remaining estimated liability is likely not material.

Table of Contents

Warranty Obligations

​

We provide a one-year warranty on our smart transmitters to our customers. We may also replace Eversense system components that do not function in accordance with the product specifications. Estimated replacement costs are recorded at the time of shipment as a charge to cost of sales in the consolidated statement of operations and are developed by analyzing product performance data and historical replacement experience, including comparing actual return management authorizations to revenues.

​

Inventory and Obsolescence

​

Inventory is valued at the lower of cost or net realizable value. Cost is determined using the standard cost method that approximates first in, first out. We record an adjustment to reduce the value of inventory for items that are potentially obsolete, where the standard costs require adjustment to the net realizable value, and are in excess of future demand taking into consideration the product shelf life. Our sensor manufacturing process can span several months, involves various contract manufacturers and includes raw components with long lead times, often resulting in significant work-in-progress inventory. However, expiry does not commence until the chemistry is applied to the sensor. We are able to isolate pre-chemistry sensor inventory in progress from post-chemistry sensor inventory and finished goods to assess against demand forecasts and customer dating requirements for potential excess or obsolete inventory. Our estimates are based on information known at the time and include factors such as anticipated future usage and sales, potential for external unfavorable conditions such as import holds or quality issues, and planned product upgrades. However, if actual product quality or conditions differ from our assumptions, additional inventory adjustments that would increase cost of sales could be required.

​

Derivative Financial Instruments

​

In connection with our issuance of the convertible senior subordinated notes due 2023, or the 2023 Notes in January 2018, we bifurcated the embedded conversion option, along with the interest make-whole provision and make-whole fundamental change provision, and recorded the embedded conversion option as a derivative liability in our consolidated balance sheets in accordance with ASC Topic 815, Derivatives and Hedging.

​

In July 2019, we issued $82.0 million in aggregate principal amount of convertible senior subordinated notes due 2025, or the 2025 Notes. In connection with the 2025 Notes, we bifurcated the embedded conversion option along with the fundamental change make-whole provision and the cash settled fundamental make-whole shares provision, and recorded the fair value of these embedded features as a derivative liability in our consolidated balance sheets in accordance with Accounting Standards Codification, or ASC, Topic 815, Derivatives and Hedging.

​

On April 21, 2020, we entered into the Highbridge Loan Agreement, in which we borrowed an aggregate principal amount of $15.0 million through the issuance and sale of the First Lien Notes and issued 1,500,000 shares of our common stock to the Lenders as a commitment fee. The First Lien Notes also contained redemption features that were evaluated for bifurcation as separate derivative instruments including the permitted prepayment put option, the mandatory accelerated redemption and the mandatory redemption and reinvestment upon an asset sale. We recorded the fair value of the embedded features in the amount of $1.0 million as a debt premium and derivative asset in our consolidated balance sheets in accordance with ASC Topic 815, Derivatives and Hedging. The derivative was adjusted to fair value at each reporting period, with the change recorded in change in fair value of derivatives that is a component of other income (expense) in our consolidated statements of operations and comprehensive loss. On August 14, 2020, we prepaid the First Lien Notes in full, including the discounted prepayment premium, in the amount of approximately $17.6 million and recognized a loss on extinguishment in the amount of $0.7 million.

​

On April 21, 2020, we entered into a Note Purchase and Exchange Agreement with certain funds managed by Highbridge providing for the exchange (the “Exchange”) of $24.0 million aggregate principal amount of our outstanding 2025 Notes for (i) $15.7 million aggregate principal amount of newly issued Second Lien Notes, (ii) 11,026,086 shares of common stock, (iii) warrants to purchase up to 4,500,000 shares of common stock at an exercise price of $0.66 per share, and (iv) $0.3 million in accrued and unpaid interest on the 2025 Notes being exchanged. On August 9, 2020, we entered into a First Amendment to Note Purchase and Exchange Agreement with Highbridge (as amended by the Amendment, the “Exchange Agreement”). The Second Lien Notes also contain redemption features that were evaluated for bifurcation as separate derivative instruments including the permitted prepayment put option, the mandatory accelerated redemption and the mandatory redemption and reinvestment upon an asset sale. Unlike the First Lien Notes,

the Second Lien Notes also permit voluntary conversion at the option of the holder as described above. We recorded the fair value of these embedded features in the amount of $1.9 million as a derivative asset in our consolidated balance sheets in accordance with ASC Topic 815, Derivatives and Hedging. The derivative is adjusted to fair value at each reporting period, with the change in the fair value recorded in change in fair value of derivatives that is a component of other income (expense) in our consolidated statement of operations and comprehensive loss. During the fiscal year ended December 31, 2020, Highbridge elected to convert the full $15.7 million of outstanding principal on the Second Lien Notes.

​

In August 2020, we issued $35.0 million in aggregate principal amount of convertible senior secured notes due 2024, or the PHC Notes. The Note Purchase Agreement also contained several provisions requiring bifurcation as a separate derivative liability including an embedded conversion feature, mandatory prepayment upon event of default that constitutes a breach of the minimum revenue financial covenant, optional redemption upon an event of default, change in interest rate after PMA approval and default interest upon an event of default. We recorded the fair value of the embedded features as a derivative liability in our consolidated balance sheets in accordance with ASC Topic 815, Derivatives and Hedging.

​

The derivative instruments are remeasured at the end of each reporting period with changes in fair value recorded in the consolidated statements of operations and comprehensive loss in other income (expense) as a change in fair value of the derivative liability. The fair value assessment incorporates management’s assumptions for probabilities of conversion occurrence through maturity, stock price, volatility, risky bond rate, and trade data when available. We engage a third-party valuation specialist to perform the valuation using the binomial option pricing model.

Revenue, net

​

Our total net revenue decreased to $4.9 million for the year ended December 31, 2020, compared to $21.3 million for the year ended December 31, 2019, a decrease of $16.4 million. This decrease was primarily due to decreased sales of the Eversense CGM System outside of the United States.

​

Cost of sales

​

Our cost of sales decreased to $22.3 million for the year ended December 31, 2020, compared to $40.7 million for the year ended December 31, 2019, a decrease of $18.4 million. This decrease was primarily attributable to decreased product costs of $17.2 million due to the temporary suspension of manufacturing activities resulting from changes made to our operational focus.

​

Gross profit (loss) was $(17.4) million and $(19.4) million for the years ended December 31, 2020 and 2019, respectively. Gross profit as a percentage of revenue, or gross margin, was (350.9)% and (91.3)% for the years ended December 31, 2020 and 2019, respectively. The decrease in gross profit was due to lower sales and inventory impairment as a result of temporary suspension of commercial activities.

​

Sales and marketing expenses

​

Sales and marketing expenses were $20.6 million for the year ended December 31, 2020, compared to $49.6 million for the year ended December 31, 2019, a decrease of $29.0 million. The decrease was primarily the result of our headcount reduction on March 26, 2020, which impacted the majority of the sales organization, resulting in a decline in salary and personnel costs of $15.4 million and a decline of $13.6 million related to travel, trade shows, consultants and other regional marketing programs to market Eversense, due to the temporary suspension of commercial activities.

​

Research and development expenses

​

Research and development expenses were $20.4 million for the year ended December 31, 2020, compared to $38.4 million for the year ended December 31, 2019, a decrease of $18.0 million. The decrease was due to decrease of $7.9 million for clinical trial costs primarily related to the PROMISE trial, $6.5 million decrease of consulting, outside services and other expenses resulting from our change in operational plans to focus on our regulatory submission for the new 180-day Eversense product in the United States, $1.9 million decrease related to lab supplies, software and travel reductions and $1.7 million decrease for salary and other personnel related costs following our reduction in workforce in March 2020.

​

General and administrative expenses

​

General and administrative expenses were $20.8 million for the year ended December 31, 2020, compared to $23.2 million for the year ended December 31, 2019, a decrease of $2.4 million. The decrease was primarily due to a $1.9 million decrease in other general and administrative costs to support our operations, which includes recruiting, IT supplies and services, and travel, $0.6 million decrease in legal expenses related to patents and trademarks, and $0.2 million decrease in salaries, bonuses and payroll related costs for reduction in headcount, offset by $0.3 million increase in occupancy cost.

Total other income (expense), net

​

Total other income (expense), net, was ($96.0) million for the year ended December 31, 2020, compared to $15.1 million for the year ended December 31, 2019, a decrease of $111.1 million. The decrease was primarily due to a $40.9 million change in fair value on our derivative liabilities, a $30.7 million loss on fair value adjustment for the Masters and Energy Capital transactions, a $20.7 million loss on extinguishment of debt, an aggregate of $12.7 million of loss on debt issuance, related to the Series A preferred stock financing and other issuance costs related to the equity line with Energy Capital, $4.4 million in interest expense and $2.3 million impairment expense related to the PHC option

and $1.7 million in lower interest income, offset by an aggregate reduction of $2.3 million in debt issuance costs and other expense.

​

Revenue

​

Our total net revenue increased to $21.3 million for the year ended December 31, 2019, compared to $18.9 million for the year ended December 31, 2018, an increase of $2.4 million. This increase was primarily due to increased U.S. sales of Eversense, net of reimbursements in connection with the Eversense Bridge Program.

​

Cost of Sales

​

Our cost of sales increased to $40.7 million for the year ended December 31, 2019, compared to $27.1 million for the year ended December 31, 2018, an increase of $13.7 million. This increase was primarily attributable to increased impairment charges of $5.3 million due to obsolete inventory and product enhancements, $3.3 million for scrap and costs to streamline our sensor supply chain, $3.0 million for warranty expenses, $1.0 million for product back-ups and replacements associated with the recall of 844 uninserted sensors in the third quarter of 2019 and a net increase of $1.1 million for packaging, warehousing and logistics related costs.

​

Gross profit was $(19.4) million and $(8.1) million for the years ended December 31, 2019 and 2018, respectively. Gross profit as a percentage of revenue, or gross margin, was (91.3)% and (43.1)% for the years ended December 31, 2019 and 2018, respectively.

Sales and marketing expenses were $49.6 million for the year ended December 31, 2019, compared to $27.7 million for the year ended December 31, 2018, an increase of $21.8 million. The increase was primarily due to increased commercialization efforts in the United States during 2019, including a $13.0 million increase in salaries, commissions and payroll related costs for additional headcount, an increase in marketing costs of $6.4 million mainly related to consultants and travel, and an increase of $2.4 million for marketing programs, customer support services and software.

​

Research and development expenses were $38.4 million for the year ended December 31, 2019, compared to $31.9 million for the year ended December 31, 2018, an increase of $6.6 million. The increase was primarily due to a $7.9 million increase related to the PROMISE clinical trial and other post-approval and feasibility studies, a $0.8 million increase in salaries, bonuses and payroll related costs for additional headcount, partially offset by a decrease in contractual services of $2.1 million due to the FDA approval of Eversense in the United States in July 2018.

​

General and administrative expenses

​

General and administrative expenses were $23.2 million for the year ended December 31, 2019, compared to $19.8 million for the year ended December 31, 2018, an increase of $3.4 million. The increase was primarily due to a $1.3 million increase in salaries, bonuses and payroll related costs for additional headcount, a $1.3 million increase in other general and administrative costs to support our operations, and a $1.1 million increase for legal, audit and consulting fees.

​

Total other expense, net

The increase was primarily due to a $29.2 million change in fair value on our derivative liabilities in connection with the 2023 and 2025 Notes in 2019, offset by a $7.3 million increase in interest expense, debt issuance costs, and loss on the extinguishment of debt associated with the modification of the 2023 Notes and issuance of the 2025 Notes in July 2019.

On November 9, 2020, we entered into an equity line agreement (the “Equity Line Agreement”) with Energy Capital, LLC, a Florida limited liability company (“Energy Capital”), which provides that, upon the terms and subject to the conditions and limitations set forth therein, Energy Capital is committed to purchase up to an aggregate of $12.0 million of shares of the Company’s newly designated series B convertible preferred stock (the “Series B Preferred Stock”) at the Company’s request from time to time during the 24-month term of the Equity Line Agreement. Under the Equity Line Agreement, beginning January 21, 2021, subject to the satisfaction of certain conditions, including that we have less than $8 million of cash, cash equivalents and other available credit (aside from availability under the Equity Line Agreement), we have the right, in our sole discretion, to present Energy Capital with a purchase notice (each, a “Regular Purchase Notice”) directing Energy Capital (as principal) to purchase shares of Series B Preferred Stock at a price of $1,000 per share (not to exceed $4.0 million worth of shares) once per month, up to an aggregate of $12.0 million of our Series B Preferred Stock at a per share price (the “Purchase Price”) equal to $1,000 per share of Series B Preferred Stock, with each share of Series B Preferred Stock initially convertible into common stock, beginning six months after the date of its issuance, at a conversion price of $0.3951 per share, subject to customary anti-dilution adjustments, including in the event of any stock split. The Equity Line Agreement provides that we shall not affect any Regular Purchase under the Equity Line Agreement on any date where the closing price of our common stock on the NYSE American is less than $0.25 without the approval of Energy Capital.

We also have the option to sell and issue PHC up to $15.0 million of convertible preferred stock on or before December 31, 2022, contingent upon obtaining approval for the 180-day Eversense product for marketing in the United States before such date.

The Series A Preferred Stock ranks senior to the common stock. Upon a liquidation, dissolution or winding up of the company, each share of Series A Preferred Stock will be entitled to receive an amount per share equal to the greater of the purchase price paid and the amount that the holder would have been entitled to receive at such time if the Series A Preferred Stock were converted into common stock.

Term Loans

​

On July 16, 2019, we entered into a Loan and Security Agreement, or the Solar Loan Agreement, with Solar Capital, Ltd., or Solar. Pursuant to the Solar Loan Agreement, on July 25, 2019, or the effective date, we borrowed the Solar Term Loan in an aggregate principal amount of $45.0 million, or the Solar Term Loan. We used $11.6 million of the Solar Term Loan to repay in full the term loans, or the Oxford/SVB Term Loans and together with the Solar Term Loan, the Term Loans, borrowed pursuant to our Amended and Restated Loan and Security Agreement with Oxford Finance LLC, or Oxford, and Silicon Valley Bank, or SVB.

​

As described in our Overview and Business Updates, on March 22, 2020 we terminated our Loan and Security Agreement with Solar and repaid the $45.0 million principal balance in full.

​

PPP Loan

​

On April 22, 2020, we received $5.8 million in loan funding from the PPP pursuant to the CARES Act, as amended by the Flexibility Act, and administered by the SBA. The unsecured loan, or the PPP Loan, is evidenced by the PPP Note dated April 21, 2020, or the PPP Note, in the principal amount of $5.8 million with Silicon Valley Bank, or the Bank.

​

Under the terms of the PPP Note and the PPP Loan, interest accrues on the outstanding principal at a rate of 1.0% per annum. The term of the PPP Note is two years, though it may be payable sooner in connection with an event of default under the PPP Note. To the extent the loan amount is not forgiven under the PPP, we are obligated to make equal monthly payments of principal and interest, beginning after determination of forgiveness by the Bank. We may apply for forgiveness any time on or before the maturity date of the loan. If we do not apply for loan forgiveness within ten months

78

Table of Contents

after the last day of the covered period, the PPP loan is no longer deferred, and we must begin paying principal and interest.

​

The CARES Act and the PPP provide a mechanism for forgiveness of up to the full amount borrowed. Under the PPP, we may apply for forgiveness for all or a part of our PPP Loan. The amount of loan proceeds eligible for forgiveness is based on a formula that takes into account a number of factors, including the amount of loan proceeds used by us during the specified period after the loan origination for certain purposes including payroll costs, interest on debt obligations incurred prior to February 15, 2020, rent payments on certain leases, and certain qualified utility payments, provided that at least 60% of the loan amount is used for eligible payroll costs; the employer maintaining or rehiring employees and maintaining salaries at certain levels; and other factors. Subject to the other requirements and limitations on loan forgiveness, only loan proceeds spent on payroll and other eligible costs during the covered specified period will qualify for forgiveness. As a result of our workforce reduction, the amount of forgiveness will correspondingly decrease.

​

The PPP Note may be prepaid in part or in full, at any time, without penalty. The PPP Note provides for certain customary events of default, including (i) failing to make a payment when due under the PPP Note, (ii) failure to do anything required by the PPP Note or any other loan document, (iii) defaults of any other loan with the Bank, (iv) failure to disclose any material fact or make a materially false or misleading representation to the Bank or SBA, (v) default on any loan or agreement with another creditor, if the Bank believes the default may materially affect our ability to pay the PPP Note, (vi) failure to pay any taxes when due, (vii) becoming the subject of a proceeding under any bankruptcy or insolvency law, having a receiver or liquidator appointed for any part of our business or property, or making an assignment for the benefit of creditors, (viii) having any adverse change in financial condition or business operation that the Bank believes may materially affect our ability to pay the PPP Note, (ix) if we reorganize, merge, consolidate, or otherwise change ownership or business structure without the Bank’s prior written consent, or (x) becoming the subject of a civil or criminal action that the Bank believes may materially affect our ability to pay the PPP Note. Upon the occurrence of an event of default, the Bank has customary remedies and may, among other things, require immediate payment of all amounts owed under the PPP Note, collect all amounts owing from us, and file suit and obtain judgment against us.

​

Highbridge Loan Agreement

​

On April 21, 2020, we entered into the Highbridge Loan Agreement, with certain funds managed by Highbridge Capital Management, LLC, or Highbridge, as the lenders (together with the other lenders from time to time party thereto, or the Lenders) and Wilmington Savings Fund Society, SCB, as collateral agent.

​

Pursuant to the Highbridge Loan Agreement, we borrowed an aggregate principal amount of $15.0 million on April 24, 2020 through the issuance and sale of First Lien Notes. In connection with the Highbridge Loan Agreement and receipt of the first tranche of borrowing, we issued 1,500,000 shares of our common stock to the Lenders as a commitment fee.

​

Upon the closing of the PHC Notes, we prepaid the First Lien Notes in full in the amount of approximately $17.6 million, which includes the discounted prepayment premium.

​

Exchange Agreement with Highbridge

​

On April 21, 2020 we entered into a Note Purchase and Exchange Agreement, or the Exchange Agreement, which we subsequently amended on August 9, 2020, with certain funds managed by Highbridge providing for the exchange of $24.0 million aggregate principal amount of our outstanding senior convertible notes due January 15, 2025, or the 2025 Notes, for (i) $15.7 million aggregate principal amount of newly issued Second Lien Secured Notes, or the Second Lien Notes, (ii) 11,026,086 shares of our common stock, (iii) warrants to purchase up to 4,500,000 shares of our common stock at an exercise price of $0.66 per share, and (iv) $0.3 million in accrued and unpaid interest on the 2025 Notes being exchanged. The exchange closed on April 24, 2020. The warrants may be exercised for cash or on a cashless basis at any time through the three year anniversary of the issuance date.

​

Table of Contents

As amended by the Amendment, effective as of the Closing Date, the holders of the Second Lien Notes had the right to convert the aggregate principal of the Second Lien Notes (together with any applicable prepayment premium) to common stock at a price per share equal to 90% of the greater of (i) the daily volume weighted average of the price per share of the common stock, on the conversion date, or if the conversion date is not a trading date, the trading day immediately prior to the conversion date and (ii) $0.33 per share. This conversion option had a daily limit of $1,000,000 in aggregate converted principal (inclusive of principal amount of First Lien Notes that were voluntarily converted). During the fiscal year ended December 31, 2020, Highbridge elected to convert the full $15.7 million of outstanding principal on the Second Lien Notes for issuance of 42,776,936 shares of common stock, which included prepayment premiums and were based off of our election of PIK interest.

​

Funding Requirements and Outlook

​

Our ability to generate revenue and achieve profitability depends on the successful commercialization and adoption of our Eversense CGM systems by diabetes patients and healthcare providers, along with future product development, regulatory approvals, and post-approval requirements. These activities, including our ongoing focus to grow covered lives through positive insurance payor policy decisions and obtain approval for Eversense 180-day product in the United States, will require significant uses of working capital through 2021 and beyond.

​

We expect that existing cash, cash equivalents and cash flows from our future operations will be sufficient to meet the Company’s current published operating plans for the foreseeable future. As part of our liquidity strategy, we will continue to monitor our capital structure and operating plans and we may access the capital markets or debt markets for additional funding if the opportunity arises to enhance our capital structure for changes to our operating plans, for financing strategic initiatives and to provide financial flexibility.

The new standard includes additional disclosure requirements regarding the range and weighted average to develop significant unobservable inputs within Level 3 fair value measurements and became effective for the Company on January 1, 2020. We have evaluated the standard and does not expect this to have a significant impact on the consolidated financial statements and related disclosures.

In August 2018, the FASB issued ASU No. 2018-15, Intangibles - Goodwill and Other - Internal-Use Software: Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement that is a Service Contract (ASU 2018-15). This new guidance requires a customer in a cloud computing arrangement to determine which implementation costs to capitalize as assets or expense as incurred. Capitalized implementation costs related to a hosting arrangement that is a service contract will be amortized over the term of the hosting arrangement, beginning when the module or component of the hosting arrangement is ready for its intended use. ASU 2018-15 is effective for public business entities for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years, and early adoption is permitted. Application of this guidance can be applied either prospectively or retrospectively. We adopted the new standard on January 1, 2020 on a prospective basis. Our adoption of ASU 2018-15 at the beginning of the first quarter of 2020 did not have a significant impact on our consolidated financial statements.

In June 2016, the FASB issued ASU 2016-13, Financial Instruments – Credit Losses: Measurement of Credit Losses on Financial Instruments, which requires entities to record expected credit losses for certain financial instruments, including trade receivables, as an allowance that reflects the entity's current estimate of credit losses expected to be

incurred. For available-for-sale debt securities in unrealized loss positions, the new standard requires allowances to be recorded instead of reducing the amortized cost of the investment. The Company does not currently hold or plan to invest in available-for-sale securities, and has not historically experienced collection issues or bad debts with trade receivables. Accordingly, the Company does not expect this to have a significant impact on its consolidated financial statements and related disclosures at this time. We will adopt this guidance on its effective date for smaller reporting companies, January 1, 2023.

In December 2019, the FASB issued ASU No. 2019-12, Simplifying the Accounting for Income Taxes, which is intended to simplify various aspects of the income tax accounting guidance, including requirements such as tax basis step-up in goodwill obtained in a transaction that is not a business combination, ownership changes in investments, and interim-period accounting for enacted changes in tax law. ASU 2019-12 is effective for public business entities for fiscal years beginning after December 15, 2020, including interim periods within those fiscal years, and early adoption is permitted. We are currently evaluating the impact that this guidance will have on our consolidated financial statements.

In August 2020, the FASB issued ASU No. 2020-06, Debt-Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging—Contract in Entity’s Own Equity (Subtopic 815-40). This new guidance is intended to reduce the complexity of accounting for convertible instruments. The guidance also addresses how convertible instruments are accounted for in the diluted earnings per share calculation and requires enhanced disclosures about the terms of convertible instruments. Entities may adopt ASU 2020-06 using either partial retrospective or fully retrospective method of transition. This ASU is effective for public business entities for fiscal years beginning after December 15, 2021, including interim periods within those fiscal years. Early adoption is permitted for fiscal years beginning December 15, 2020, including interim periods within that fiscal year. We are currently evaluating the impact that this guidance will have on our consolidated financial statements, but are likely to early adopt for fiscal year 2021.

​

We have evaluated all other issued unadopted ASUs and believe the adoption of these standards will not have a material impact on our consolidated statements of operations and comprehensive loss, balance sheets, or cash flows.
