PART I

Overview

We are a commercial stage medical technology company focused on designing, developing and marketing products that improve the quality of life for patients who suffer from psychiatric disorders. Our first commercial product, the NeuroStar Advanced Therapy System, is a non-invasive and non-systemic office-based treatment that uses transcranial magnetic stimulation, or TMS, to create a pulsed, MRI-strength magnetic field that induces electrical currents designed to stimulate specific areas of the brain associated with mood. The system is cleared by the United States Food and Drug Administration, or FDA, to treat adult patients with major depressive disorder, or MDD, that have failed to achieve satisfactory improvement from prior antidepressant medication in the current MDD episode. NeuroStar Advanced Therapy is safe, clinically effective, reproducible and precise and we believe is supported by the largest clinical data set of any competing TMS system. We believe we are the market leader in TMS therapy based on our U.S. installed base of 907 active NeuroStar Advanced Therapy Systems in approximately 707 psychiatrist offices as of December 31, 2018 and the estimated 62,900 patients treated with approximately 2.3 million treatment sessions through such date. We generated revenues of $52.8 million for the year ended December 31, 2018.

MDD is a mood disorder characterized by the presence of one or both of two major diagnostic criteria: a depressed mood or loss of interest in pleasure that continues for at least two weeks. The presence of at least one of these diagnostic symptoms must be accompanied by several of the following additional symptoms: sleep disturbance, changes in appetite, sexual dysfunction, anxiety, fatigue, difficulty concentrating and suicidal thinking. MDD is a recurrent disease and follows a fluctuating course over an individual’s lifetime, with periods of remission and relapse.

The World Health Organization, or WHO, ranks MDD as the single largest contributor to global disability and a major contributor to suicide worldwide. According to a study published in the Journal of Clinical Psychiatry, the economic burden of the disease was estimated to be $210 billion in 2010 in the United States, including outpatient and inpatient medical costs, pharmacy costs, suicide related costs and workplace costs. A study published in Psychological Medicine reported a global incidence rate of MDD is 3.0% and the WHO estimates that there are over 300 million people in the world living with depression. Based on U.S. Census Bureau data and a study published in the Journal of the American Medical Association, we estimate that approximately 21 million people in the United States suffer from MDD annually. Of these people, we estimate approximately 13.3 million are adults aged 22 to 70 years, of whom an estimated 7.6 million, based on data from the Journal of the American Medical Association, are being treated by a psychiatrist. We estimate, based on data from the Sequenced Treatment Alternatives to Relieve Depression, or the STAR*D study, that approximately 5.5 million of these patients have failed to achieve remission of their MDD from their prior antidepressant medication therapy and that approximately 3.8 million of those patients have commercial insurance or Medicare coverage for NeuroStar Advanced Therapy. As a result, based on our expected revenues for a standard course of treatment, we believe our total annual addressable market opportunity for treatment sessions in the United States is approximately $9.6 billion.

Initial treatment options for MDD often consist of antidepressant medication prescribed by a primary care physician. Although a variety of antidepressant medications are available, drug therapy has two primary limitations: limited effectiveness and treatment-emergent side effects. These limitations were demonstrated in the STAR*D study, a large clinical trial funded by the U.S. National Institute of Mental Health, or NIMH, that enrolled more than 4,000 adult MDD patients at 41 clinical sites to examine the outcomes to a sequenced series of antidepressant medication attempts that mimicked best practices. In the study, approximately 28% and 21% of patients achieved remission in their first and second medication attempts, respectively. Many patients taking antidepressant medications experience intolerable or troubling side effects that contribute to a delay or failure in attaining an effective or optimal antidepressant dose, poor patient treatment adherence or discontinuation of treatment therapy. The likelihood of achieving remission is limited and declines with each successive medication attempt.

2

TMS is considered to be an appropriate therapy for the treatment of MDD patients who have failed to achieve satisfactory improvement from prior antidepressant medication. TMS is typically performed as an office-based procedure using a capital equipment system designed to deliver the magnetic pulses necessary to stimulate the specific areas of the brain associated with mood. A course of treatment typically requires treatment sessions five times a week for up to six weeks that can last from as low as three to as long as 45 minutes per session. The effectiveness of TMS depends on the psychiatrist’s ability to deliver a precise amount of magnetic pulses to a specific area of the brain in a manner that can be consistently repeated during each treatment session. While TMS has been demonstrated to be a safe and effective treatment alternative for patients suffering from MDD, we believe that competing TMS systems have experienced limited adoption because of their lack of the following: the ability to reproduce consistent treatments, significant clinical data from randomized outcome trials, practice development resources and a cloud-based practice management system.

We designed the NeuroStar Advanced Therapy as a non-invasive therapeutic alternative to treat patients who suffer from MDD and to address many of the key limitations of existing treatment options. We believe our NeuroStar Advanced Therapy provides our psychiatrist customers and their patients with several benefits, including clinically demonstrated response and remission with durable results, a demonstrated safety profile with limited treatment-emergent side effects and high patient adherence. Additionally, NeuroStar Advanced Therapy was designed to provide a precise and reproducible office-based therapy that is also efficient and convenient. Our therapy is delivered without general anesthesia or sedation, enabling the patient to drive and resume normal activities immediately following each treatment session. We couple our product’s clinical benefits with significant practice development resources, on-site clinical training and reimbursement and service support to help our psychiatrist customers develop a successful NeuroStar Advanced Therapy practice. We also provide cloud-based practice management solutions that enhance convenience for both psychiatrists and patients. Based on our commercial data, we believe psychiatrists can recoup their initial capital investment in our system by providing a standard course of treatment to approximately 12 patients, assuming these patients receive reimbursement from Medicare or commercial insurance at rates that are similar to what our customers have observed for existing and prior patients. We believe psychiatrists can generate approximately $7,500 to $10,000 of revenue per patient for a standard course of treatment, which may provide meaningful incremental income to their practices.

The safety, effectiveness and durability of NeuroStar Advanced Therapy is supported by a large clinical data set published in 23 articles in peer-reviewed medical journals, including from 11 clinical studies that have collectively enrolled more than 900 adult patients suffering from MDD. In a 307 patient, naturalistic, prospective, observational trial conducted at 42 U.S. clinical sites in patients who had tried and failed to receive relief from one or more medication trials in their current MDD episode, following an acute course of NeuroStar Advanced Therapy, 58% of patients responded, which means they achieved a clinically meaningful reduction in symptoms, and 37% achieved remission. Response and remission were maintained over a 12-month period for a majority of these patients. In the STAR*D study approximately 28% and 21% of patients achieved remission in their first and second medication trials, respectively.

Our growth strategy includes expanding our commercialization efforts in the United States, expanding international opportunities and pursuing pipeline development of our therapy for additional indications. Outside the United States, our products have received marketing authorizations in the European Union and Japan. Our initial international commercial focus is Japan, which has the third largest healthcare spend globally. We have entered into an exclusive distribution agreement with Teijin Pharma Limited, or Teijin, a leading Japanese healthcare company, to further expand our commercialization efforts in this market. We are also evaluating the use of enhancements to our NeuroStar Advanced Therapy System to treat additional indications, which may include bipolar depression and post-traumatic stress disorder.

As of December 31, 2018, we had an installed base of 907 active NeuroStar Advanced Therapy Systems in the United States. We currently sell our NeuroStar Advanced Therapy System and recurring treatment sessions in the United States through our sales and customer support team, which was comprised of 133 people as of December 31, 2018. Our sales force primarily targets 15,100 psychiatrists at 3,600 high-decile psychiatric practices that we estimate, based on data from Symphony Health and our own internal estimates, treat approximately 33% of the total MDD patients in the United States who meet our labeled indication and are insured. Patients are reimbursed by Medicare and the vast majority of commercial payors in the United States for treatment sessions utilizing our NeuroStar Advanced Therapy System.

We generate revenues from initial capital sales of our systems, sales of our recurring treatment sessions and from service and repair and extended warranty contracts. We derive the majority of our revenues from recurring treatment sessions. For the year ended December 31, 2018, we generated revenues of $52.8 million and had a net loss of $24.1 million. Our revenues increased 31% during the year ended December 31, 2018 compared to the year ended December 31, 2017. For the year ended December 31, 2018, our U.S. revenues were $51.5 million, compared to $39.9 million for the year ended December 31, 2017, which represented an increase of 29% compared to the prior period. Revenues from treatment sessions represented 69% of our U.S. revenues for the year ended December 31, 2018 compared to 71% of our U.S. revenues for the prior year.

Market Opportunity and Major Depressive Disorder

Market Opportunity

The WHO estimates that there are over 300 million people in the world living with depression and ranks MDD as the single largest contributor to global disability and a major contributor to suicide worldwide. In the United States, the economic burden of the disease was estimated by the Journal of Clinical Psychiatry to be $210 billion in 2010, including outpatient and inpatient medical costs, pharmacy costs, suicide related costs and workplace costs. There were approximately 333 million antidepressant medication prescriptions written in the United States in 2017, representing pharmaceutical sales totaling $5.0 billion, according to IMS Health. Based on U.S. Census Bureau data and a study published in the Journal of the American Medical Association, we estimate that approximately 21 million people in the United States suffer from MDD annually. Of these people, we estimate approximately 13.3 million are adults aged 22 to 70 years, of whom an estimated 7.6 million, based on data from the Journal of the American Medical Association, are being treated by a psychiatrist. We estimate, based on data from the STAR*D study, that approximately 5.5 million of these patients have failed to achieve remission of their MDD from their prior antidepressant medication therapy and that approximately 3.8 million of those patients have commercial insurance or Medicare coverage for the NeuroStar Advanced Therapy. As a result, based on our expected revenues for a standard course of treatment, we believe our total annual addressable market opportunity for treatment sessions in the United States is approximately $9.6 billion.

In Japan, the country with the third highest aggregate healthcare expenditures worldwide according to Deloitte, we estimate, based on data from the National Center for Biotechnology and Information, that approximately 2.4 million adults suffer from MDD and approximately 655,000 of these adults are being treated for their MDD by a psychiatrist. We estimate, based on data from the STAR*D study, that approximately 475,000 of these patients, all of whom are covered by Japan’s single payor healthcare system, have failed to achieve remission of their MDD from prior antidepressant medication therapy and are candidates for treatment with NeuroStar Advanced Therapy. As a result, we believe our total addressable market opportunity for treatment sessions in Japan is over $1.0 billion, assuming psychiatrist reimbursement levels per treatment course per patient are similar to those in the United States.

Major Depressive Disorder

Disease Overview

MDD is a mood disorder characterized by the presence of one or both of two major diagnostic criteria that continues for at least two weeks: a depressed mood or loss of interest in pleasure. The presence of at least one of these diagnostic symptoms must be accompanied by several of the following additional symptoms, for a total of five or more symptoms: sleep disturbance, changes in appetite, sexual dysfunction, anxiety, fatigue, difficulty concentrating and suicidal thinking. In order to be diagnosed with MDD, a patient must display symptoms that are present most of the day, nearly every day, for at least two weeks. A diagnosis of MDD is established by clinical interview and an assessment of whether a patient reports a collection of symptoms defined in the American Psychiatric Association’s Diagnostic and Statistical Manual of Mental Disorders, fifth edition, or DSM-5. The severity of a patient’s symptoms is typically measured by a standardized rating scale from a self-reported questionnaire, such as the Patient Health Questionnaire-9, or PHQ-9, or from an observer-dependent interview, such as the Hamilton Depression Rating Scale, or HAMD. Based in part on these rating scale measures, MDD can be graded on a continuum from mild to severe. The symptoms of the disease may result in role impairment, which refers to a loss of functioning or enjoyment in work, or impairment of household relationships and/or social roles. MDD is often accompanied by, or comorbid with, other mental disorders, with an estimated three-fourths of patients with recurrent MDD suffering from another psychiatric illness or substance abuse disorder. MDD patients also have an increased risk of death from suicide and other more typical causes, such as heart disease.

4

MDD is a recurrent disease and follows a fluctuating course over an individual’s lifetime, with periods of remission and relapse. If an initial episode of MDD is resolved, the return of depressive symptoms during the first nine months thereafter is referred to as a relapse of the illness and is generally considered to be part of the same depressive episode. When depressive symptoms return more than 12 months after the initial episode of MDD is resolved, it is considered to be a recurrence of the illness and is deemed a new and distinct episode. A response to treatment is commonly measured as a clinically significant decrease in symptoms on a standardized rating scale from baseline scores. When a patient shows no or nearly no symptoms, the patient is referred to as being in remission. An average episode of MDD lasts approximately four to eight months and approximately three-fourths of all patients who experience an episode of MDD will experience recovery within a year. However, experiencing one episode of MDD places an individual at an estimated 50% risk of experiencing an additional episode of MDD. Approximately 80% of those individuals who have experienced two episodes of MDD will experience an additional episode.

Neuroscience of MDD

The exact causes of MDD are not known but, as with many psychiatric disorders, a variety of factors may be involved, including the physical and chemical characteristics of the brain, hormonal changes, genetics, acute life events, chronic stress, childhood exposure to adversity and other environmental factors. Researchers have identified a network in the brain that affects a person’s mood, which can play a significant role in MDD and includes the prefrontal cortex, the anterior cingulate cortex and the limbic brain structures. The basic unit of organization in this network of the brain is the neuron, a specialized cell that responds to both chemical and electrical signals. The release of chemical messengers, or neurotransmitters, in the brain occurs across synapses, or the space between neurons. This release of neurotransmitters results in changes in the electrical properties of the receiving neuron, which in turn triggers a cascade of neuron-to-neuron electro-chemical reactions along a pathway of the brain referred to as a neuronal circuit.

The following diagram depicts the chemical reactions across the neuronal network:

Neurotransmission Mechanism

This communication process across different regions of the brain is ordinarily self-regulated by feedback mechanisms that instruct the originating neuron to stop releasing the neurotransmitter and start reabsorbing it into the cell, a process called reabsorption or reuptake.

In people with MDD, however, this complex system of neuronal communication does not function properly. Receptors may be either oversensitive or insensitive to a specific neurotransmitter, causing their response to its release to be excessive or inadequate. The signal might also be weakened if the originating cell produces too little of a neurotransmitter or if an overly efficient reuptake process reabsorbs too much of the neurotransmitter before the molecules have the chance to bind to the receptors on other neurons.

5

One of the most important discoveries in neuroscience has been the recognition that improper regulation of one or more of the three major neurotransmitters, serotonin, norepinephrine and dopamine, plays a key role in a patient’s depression. This understanding has guided psychiatric drug development and the treatment of depression for more than three decades by placing a major focus on targeting chemically-based mechanisms. The relatively recent introduction of TMS as a targeted, circuit-based treatment option has reintroduced the importance of electrical mechanisms in restoring proper function to neuronal pathways to treat depression.

Current Treatment Landscape

First Line Therapy

In the United States, an initial diagnosis of adult MDD is typically made by the patient’s primary care physician. Upon diagnosis, the most common form of treatment is antidepressant medication, which may or may not be accompanied by psychotherapy. The physician typically discusses a number of different treatment options and then designs a treatment plan tailored to the patient’s specific symptoms, personal preferences and the psychiatric services that are available near the patient’s home.

The most commonly prescribed antidepressant medications are selective serotonin reuptake inhibitors, or SSRIs. SSRIs primarily affect the levels and activity of serotonin in the brain and attempt to address depression by blocking the reuptake of this neurotransmitter, thereby making more serotonin available. During the initial treatment course, a patient may experience uncomfortable side effects and it is common for a patient and the primary care physician to spend time testing different medications within the same and different chemical classes before arriving at a medication regimen that provides symptom relief and is tolerable. Different classes of antidepressant medications may also work on different combinations of underlying neurotransmitters. For example, serotonin norepinephrine reuptake inhibitors, or SNRIs, work by blocking the reuptake of both serotonin and norepinephrine. Other medications may have more diverse effects on all three major neurotransmitters.

Depression-focused psychotherapies are a commonly recommended treatment option for MDD and are generally used in conjunction with an antidepressant medication. The two most well studied and commonly available psychotherapy techniques include cognitive behavioral therapy and interpersonal psychotherapy. These are interactive therapies between a trained professional and a patient.

Second Line Therapy

If initial treatment approaches do not adequately relieve a patient’s symptoms, a primary care physician will often make a referral for consultation with a psychiatrist trained in psychopharmacology. There are a wide array of options that a psychiatrist may consider as second line therapies after an initial treatment has failed. For example, a psychiatrist may recommend either combining two or more antidepressant medications, which is referred to as combination therapy, or using a second medication such as an atypical antipsychotic that is not an antidepressant along with the initial antidepressant medication to augment the efficacy of such antidepressant, which is referred to as augmentation.

Another second line therapy is TMS, which is considered to be an appropriate alternative for the treatment of a patient with MDD who has failed to achieve satisfactory improvement from prior antidepressant medication in the current MDD episode. TMS differs from drug therapy approaches by using a pulsed, MRI-strength magnetic field to induce electrical currents designed to stimulate specific areas of the brain associated with mood. The target for brain stimulation is the prefrontal cortex, which serves as a starting point to regulate the neuronal circuitry connected to this region of the brain. This stimulation triggers a cascading electro-chemical effect that can pass along the neuronal circuit and reach into the deeper structures of the brain that also regulate mood. This action changes the connections among these structures in a manner that improves the activity of the neuronal circuit and results in an improvement in mood. TMS is typically performed as an office-based procedure using a piece of capital equipment designed to deliver the magnetic pulses necessary to stimulate the neurons. A course of treatment typically requires treatment sessions five times a week for up to six weeks that can last from 19 to as long as 45 minutes per session. The effectiveness of TMS therapy depends on the psychiatrist’s ability to deliver a precise amount of magnetic pulses to a specific area of the brain in a manner that can be consistently repeated during each treatment session.

6

Later Stage Treatment Options

More aggressive options, which are associated with greater medical risk, are sometimes considered for patients that require later stages of treatment and include electroconvulsive therapy, or ECT, and vagus nerve stimulation, or VNS. ECT is a hospital-based treatment approach that is usually reserved for the most critical MDD patients and is considered most frequently in instances where the patient is experiencing catatonia, acute suicidal behaviors requiring inpatient hospitalization or psychotic symptoms. ECT involves the direct application of high voltage electrical current to the surface of the head and must be administered under anesthesia in a controlled hospital setting. VNS is considered the most invasive treatment option currently approved by the FDA for MDD patients who have proven to be severely treatment resistant. VNS involves the surgical implantation of an electrode wrapped around the vagus nerve, which travels through the neck near the carotid artery, and utilizes a pulse generator that is separately implanted under the skin near the patient’s collarbone. The pulse generator sends electrical impulses to the electrode throughout the day with the goal of modifying the regions of the brain known to be involved in the regulation of mood.

A general overview of the treatment sequence for a patient with MDD is shown in the diagram below.

Limitations of Current Therapies

Antidepressant medication therapy

Although a variety of antidepressant medications are available for the treatment of MDD, antidepressant therapy has two primary limitations: limited efficacy and treatment-emergent side effects that interfere with patient adherence to the prescribed treatment regimen. These limitations were demonstrated in the STAR*D study. This study was sponsored by the NIMH and enrolled more than 4,000 adult patients at 41 clinical sites, including outpatients with nonpsychotic MDD. The trial examined the outcomes to a sequenced series of antidepressant medication treatment options that mimicked best practices. Patients whose depression did not remit after the initial treatment trial of using a single-medication SSRI treatment were able to participate in a sequence of up to three treatment trials. The progression that followed included switching to a different class and more complex combination and augmentation treatments for patients who were unable to achieve remission with each of the trials. Brain stimulation techniques, including ECT and VNS, were not examined in this study.

7

Since the publication of the STAR*D study results, additional drug therapies have been introduced, including most prominently atypical antipsychotics, which are used as augmentation agents for patients with partial or non-response to initial antidepressant medications given alone. Unfortunately, these augmentation treatments have not significantly improved overall MDD patient response rates and have also introduced additional side effects.

8

Depression-Focused Psychotherapies

Antidepressant medication therapy for MDD is often administered along with a recommendation for a depression-focused psychotherapy. While these treatment options have demonstrated efficacy in some clinical studies, they also are associated with limitations in practice. For instance, the experience level of the therapist may significantly affect the treatment outcome. Additionally, in order to access these treatments, patients usually require a referral to a psychotherapist who may be located at a different clinical site than their treating psychiatrist. Psychotherapy requires a commitment by a patient to numerous treatment sessions in order to potentially achieve significant improvement, with a typical treatment regimen consisting of 16 sessions.

Later Stage Treatment Options

Both ECT and VNS have significant drawbacks. ECT requires general anesthesia and is administered in a controlled hospital setting with access to emergency resuscitation equipment. ECT is typically administered three times per week for up to 12 treatments, with some patients requiring as many as 20 treatments. ECT patients may experience confusion and memory loss, the two most common side effects of ECT treatments, immediately following a treatment session. Other side effects may include nausea, headache, jaw pain, muscle ache, hypertension and hypotension and life threatening complications including adverse reactions to anesthesia, arrhythmias, ischemia or prolonged seizures. Because of the potentially disabling side effects of ECT, the patient is typically unable to work for the duration of the course of treatment. VNS is considered the most invasive treatment option currently approved by the FDA for MDD patients who have proven to be severely treatment resistant. VNS includes surgical related risks, such as infection or local damage to the recurrent laryngeal nerve, which may lead to permanent voice alteration. Other drawbacks of VNS include the development of cardiac arrhythmias and the periodic repeat surgeries required to replace the pulse generator battery. Finally, reimbursement for the implantation and ongoing monitoring of the VNS device remains problematic, limiting access to the procedure for most patients.

Transcranial Magnetic Stimulation

While TMS has been demonstrated to be a safe and effective treatment alternative for patients suffering from MDD, we believe that most TMS systems have experienced limited adoption for several reasons, including:

The NeuroStar Advanced Therapy System

Product

Our NeuroStar Advanced Therapy System is comprised of the NeuroStar Mobile Console, Patient Positioning System, NeuroStar Treatment Coil and TrakStar practice management system. NeuroStar Treatment Sessions and SenStar Treatment Links, which we refer to as treatment sessions, represent the consumable portion of the NeuroStar Advanced Therapy Treatment System.

NeuroStar Mobile Console and Patient Positioning System

Our NeuroStar Mobile Console and Patient Positioning System are comprised of the following components:

NeuroStar Treatment Coil

SenStar

SenStar is a thin, flexible electronic circuit, as shown in the figure below, that functions in both the treatment delivery and procedure fee management for our NeuroStar Advanced Therapy System. Embedded in each SenStar is a magnetic field detector. At the start of each treatment, the NeuroStar Advanced Therapy System performs a self-test that includes verifying the magnetic field is operating within the specified limits. Each SenStar also includes a sensory guard to reduce topical irritation and improve patient comfort at the skin-coil interface.

14

SenStars also contain a patented contact sensor that allows the NeuroStar Advanced Therapy System to monitor and provide real-time visual feedback to the operator that the NeuroStar Treatment Coil is in proper contact with the patient’s head. The system tracks any pulses lost during treatment and will highlight lost pulses on the graphical user interface. At the end of treatment, the system allows the operator to administer any missed pulses to complete the full prescribed dose.

We sell two versions of the SenStar: the SenStar Treatment Link and the SenStar Connect. SenStar Connect is a multi-use device for the U.S. market. To activate a treatment session, a provider needs to purchase an encrypted activation code to enable the SenStar Connect to deliver one treatment session. NeuroStar Treatment Sessions are purchasable online 24 hours a day, any day of the year. The treatment inventory is electronically managed between the NeuroStar Advanced Therapy System and TrakStar systems using digital encryption technology. SenStar Treatment Link is a single use consumable. SenStar treatment links are used outside the United States and enable one treatment session. Each is programmed for the country of use.

TrakStar Practice Management System

The TrakStar patient data management system component is a cloud or local application that interfaces with the NeuroStar Advanced Therapy Systems. TrakStar maintains patient information, prescription, treatment and medication history, positioning coordinates, depression scores and psychiatrist notes.

TrakStar automatically synchronizes patient data on all NeuroStar Advanced Therapy Systems on the network. Thus the information to treat a patient is available on every system in every office within a practice. After each treatment is completed, the data is automatically uploaded to TrakStar. This seamless data integration simplifies record management and office workflow. TrakStar supports multiple reports including patient treatment history, patient depression score trending, practice outcomes and system utilization.

TrakStar cloud allows the psychiatrist to see status of other NeuroStar Advanced Therapy Systems in real-time, and access patient data anywhere and anytime using an internet browser. TrakStar cloud is hosted in Microsoft Azure and employs multiple levels of security. Patient data is encrypted both in transit and at rest. Third-party experts successfully completed penetration testing and an overall business security assessment and certified us as compliant with National Institute of Standards and Technology, or NIST, and Health Information Technology for Economic and Clinical Health, or HITECH, standards. We also monitor traffic for cybersecurity threats on an ongoing basis.

The NeuroStar Advanced Therapy Process

The Treatment Procedure

NeuroStar Advanced Therapy is an in-office treatment that has been cleared to be performed in as little as 19 minutes per session (but may take up to 39 minutes due to patient sensitivity or at the discretion of the treating psychiatrist) and is performed while the patient is awake, alert and seated and reclined comfortably in the treatment chair. A course of treatment consists of sessions administered five days a week for up to six weeks. During the first treatment session, two essential steps are performed. First, the patient’s cortex is mapped with the NeuroStar Treatment Coil to identify the area of the brain controlling the thumb. Once the specific location on the motor cortex is found, the second step involves the use of a proprietary software algorithm, which assists the psychiatrist in estimating the physiologically appropriate magnetic field intensity for each treatment session based on the intensity needed to stimulate movement in the thumb. After these two steps are performed, the location of the motor cortex then also serves as a reference point to enable the psychiatrist to properly position the NeuroStar Treatment Coil over the left prefrontal cortical surface, resting the coil lightly in contact with the patient’s scalp. Accuracy of positioning of the treatment coil for pulse delivery is assured by use of the NeuroStar Advanced Therapy System’s three-dimensional positioning device. Once the coil is properly positioned, the device delivers NeuroStar Advanced Therapy using a highly targeted pulsed magnetic field to stimulate cortical neurons. Our therapy provides targeted stimulation of the prefrontal cortex and engages the neuronal circuitry connected to this region and known to be involved in the regulation of mood.

During treatment, accurate positioning of our NeuroStar Treatment Coil is maintained by use of a proprietary contact sensing and navigation system, which helps to ensure precise targeting of the treatment and assurance of accurate therapeutic dosing for each session. The patient typically hears a clicking sound during coil operation and feels a tapping sensation on the head for the duration of the session. Over the course of each treatment, the patient receives 3,000 pulses. Real-time feedback ensures the patient receives a full dose with safe and effective care. When the session is completed, the psychiatrist removes the coil and the patient is able to immediately resume normal activities.

16

The Patient Experience

Our clinical studies indicate that most patients find the NeuroStar Advanced Therapy easy to tolerate when contrasted with alternative MDD treatments. After completion of a treatment session, a patient may immediately resume his or her normal activities, including work and exercise. NeuroStar Advanced Therapy patients generally do not experience the systemic side effects associated with drug therapy. The most typical side effect after treatment with NeuroStar Advanced Therapy, as shown in the figure below, is pain or discomfort near the treatment area, which is generally temporary and typically self-resolves within one week. In our sham-controlled clinical trials, approximately 5% of patients discontinued treatment due to adverse events.

Potential Indications for Use and Research and Development

We selectively invest in research and development for the use of the NeuroStar Advanced Therapy System in psychiatric disorders. Throughout our history, we have provided material support to 50 investigator-initiated trials of such prospective additional indications. We are currently considering a number of potential future indications for the use of the NeuroStar Advanced Therapy System, including, but not limited to, those described below.

17

Bipolar Depression

Bipolar depression is a psychiatric disorder characterized by a recurrent episodes of mania and depression. The depressed phase of bipolar disorder is considered to be a form of treatment resistant depression and is the most difficult to treat phase of bipolar disorder. The depressive episode diagnostic criteria in bipolar depression are identical to our current MDD indication. Although bipolar depression represents a smaller market than MDD, this disease state has few treatment options available and many patients experience suboptimal outcomes. Current treatment options for patients with bipolar depression include the use of mood stabilizers, including lithium carbonate, anticonvulsant, and second-generation antipsychotics. While these treatments are effective in managing the recurrent mania, there are few effective treatments for the depressed phase of the illness. For example, antidepressant medications may lead to instability in resolution of the manic episodes if administered alone, and the use of second-generation antipsychotic medications can be associated with undesirable long-term medical side effects, including weight gain or the development of metabolic syndrome. Based on early research, we are evaluating whether treatment with our NeuroStar Advanced Therapy System could be beneficial to these patients. If we were to pursue an additional indication in bipolar depression, we would need to conduct additional clinical trials, file an investigational device exemption and clinical trial protocols with the FDA, submit a 510(k) pre-market notification and receive clearance prior to commercialization.

Post-Traumatic Stress Disorder

Post-traumatic stress disorder, or PTSD, is a psychiatric disorder that develops in some people who have experienced an overwhelming traumatic event, such as witnessing death in a military or civilian setting, or as a result of severe physical abuse such as assault or rape. This exposure to a traumatic stressor can lead to a later unwanted re-experiencing of symptoms, avoidance behavior, alteration in cognition and mood and states of increased physiological arousal. Treatment options for PTSD include psychotherapy and SSRI antidepressant medications. We believe NeuroStar Advanced Therapy may represent a potential new treatment option for PTSD patients. If we were to pursue an additional indication in PTSD, we would need to conduct additional clinical trials, file an investigational device exemption and clinical trial protocols with the FDA, submit a 510(k) pre-market notification and receive clearance prior to commercialization.

Adolescent MDD

We completed patient enrollment with 112 adolescent MDD patients in a prospective, 13-center, randomized, sham-controlled, double-blind pivotal clinical trial with three phases that mirrors the design of our original adult, randomized, controlled trial. The purpose of this study is to evaluate the acute and long-term safety and efficacy of NeuroStar Advanced Therapy in treating adolescents with MDD. The trial utilizes a double-blind control design to minimize variability and allow for blinded assessment of the safety and efficacy of NeuroStar Advanced Therapy, using an active NeuroStar Treatment Coil compared to a system utilizing a sham NeuroStar Treatment Coil. Patients were randomly allocated in a one-to-one ratio to either active NeuroStar Treatment Coil or sham NeuroStar Treatment Coil. At the time of enrollment, patients were antidepressant-free for at least one week and up to four weeks, depending on medication washout period.

The first phase is designed to evaluate the antidepressant effects of active NeuroStar Advanced Therapy compared with sham treatment when administered five times per week for a six week acute course of therapy. The primary endpoint of this phase is the difference between active and sham arms using the 24-Item Hamilton Depression Rating Scale, or HAMD24, total score change from baseline score over the six week acute phase. Safety will be assessed at every treatment visit by recording adverse events. We are currently completing the analysis of all phases of the study, including the randomized controlled trial, open label extension and six-month follow-up study. Based on a preliminary analysis conducted in the second quarter of 2018, the primary endpoint in the first phase of the trial was not met. Although we cannot directly attribute clinical trial outcomes from other studies to our own clinical trials, we believe several clinical trials for antidepressant medications failed to meet the primary efficacy endpoint in their studies for MDD in adolescents and children. These include duloxetine, venlafaxine and, most recently, desvenlafaxine. To date, the data safety monitoring board has not identified any serious safety issues in the study population, including suicidality and seizure.

18

Consistent with our clinical trial protocols, patients who have completed the first phase were eligible to participate in the second phase of our clinical trial, which is a separate, open-label extension study. The second phase trial is designed to evaluate the benefit of active treatment administered five times per week for a six-week acute course of NeuroStar Advanced Therapy in patients who received active or sham treatment and did not receive protocol-defined clinical benefit in the first phase. Patients remain antidepressant medication free during the second phase. This trial will provide descriptive data on patients who are switched from sham to active treatments or receive a longer course of active treatment up to 12 weeks.

Patients who met the criteria for at least partial response in either the first or second phases of the trial were eligible to be followed in a third phase that will be a separate six-month follow up phase. Patients entering the third phase first undergo a three-week transition during which they will be gradually tapered off NeuroStar Advanced Therapy. Patients who experience symptom worsening during this phase of the study may receive reintroduction of NeuroStar Advanced Therapy. Patients remain antidepressant medication free during the third phase of the trial. The purpose of this phase is to provide descriptive data on the six-month follow-up period and any retreatments received by patients.

Although we believe we are unlikely to seek a label expansion for the NeuroStar Advanced Therapy System for the treatment of adolescent MDD, we plan to evaluate next steps with respect to our clinical development efforts for this indication following the completion of the data analysis. We do not expect that the results from the clinical trial will be sufficient to obtain approval of our system for this indication. Nevertheless, we do not believe these clinical trial results or the failure to obtain approval of our NeuroStar Advanced Therapy System for the treatment of adolescents with MDD will have a material impact on our current or future business.

Research and Development and Clinical Operations

Continued innovation through research and development is critical to our future success as a leader in improving the quality of life for patients who suffer from psychiatric disorders. Our research and development activity is performed with a mix of internal and third party contract resources. As of December 31, 2018, our research and development and clinical operations team consisted of 33 employees with expertise in electronic, mechanical or electrical design, software, biomedical engineering, neuroscience and clinical trial design and management. Our research and development expenses, including spending on our clinical trials and development efforts, totaled $8.2 million and $7.9 million for the years ended December 31, 2018 and 2017, respectively. Our current research and development efforts are focused primarily on platform extensions for our NeuroStar Advanced Therapy System and a series of enhancements to our TrakStar cloud-based software application. Our clinical development efforts are focused on further expanding the use of our products in additional indications. We coordinate our development efforts with our intellectual property strategies in order to enhance our ability to obtain patent and other intellectual property protection.

Clinical Results and Studies

Overview of Clinical Trial Evidence for the Safety and Efficacy of NeuroStar Advanced Therapy

Clinical evidence supporting the safety and efficacy of NeuroStar Advanced Therapy has been published in 23 peer reviewed medical journals, involving an aggregate of over 900 adult patients and more than 60 investigators. We have sponsored the largest prospective, multisite, randomized, sham-controlled trial ever conducted of a TMS device, enrolling 325 patients with treatment resistant MDD at 23 U.S. and international study sites. Results from this trial served as the basis of our initial FDA 510(k) clearance of the NeuroStar Advanced Therapy System in 2008. The clinical data from this trial were reported in Biological Psychiatry in 2007. A second, industry-independent prospective, multisite, randomized, sham-controlled trial, funded by the NIMH using the NeuroStar Advanced Therapy System, enrolled 199 patients with treatment resistant MDD across four major academic medical centers in the United States. The clinical data from this trial were submitted to the FDA in 2014, leading to an expanded labeling for our NeuroStar Advanced Therapy System for an indication of use in adult patients who have failed to benefit from one or more prior antidepressant medications in the current episode of MDD. This data was published in 2010 in Archives of General Psychiatry, now published as JAMA Psychiatry. We sponsored the largest, post-market naturalistic outcomes study of the use of the NeuroStar Advanced Therapy System in routine clinical practice. This study enrolled 307 patients with treatment resistant MDD seeking care at 42 U.S. study sites. Patients

19

in this study were assessed at the beginning and end of their prescribed acute treatment course, and 257 of these patients agreed to be followed for a period of 12 months to characterize the durability of the long-term outcome in clinical practice. Results of this study were published in the Journal of Clinical Psychiatry in 2012 and in CNS Spectrums in 2014.

Efficacy endpoints reported in these clinical trials used validated and well-accepted measures of symptomatic benefit to characterize antidepressant medication treatment in clinical trials and included those measures listed in Figure 1. An accepted goal of treatment with an antidepressant is the definitive resolution of the symptoms, which is defined as remission. Remission is defined using a validated, clinician-administered rating scale such as the 17 or 24-item versions of HAMD or the Montgomery-Asberg Depression Rating Scale, or MADRS. Patients who achieve an endpoint score below 8 points on the 17-item HAMD, below 11 points on the 24-item HAMD or below 10 points on the MADRS, are considered to have reached remission of illness. A clinically global, psychiatrist rated scale, such as the Clinical Global Impressions-Severity of Illness, or CGI-S, scale can also grade remission if a patient reaches an end of treatment score of one or two on that scale.

Figure 1. Validated measures of symptomatic benefit to characterize antidepressant treatment effect.

Patient-rated outcomes are also used to verify symptom improvement. In the NeuroStar Advanced Therapy clinical trial data, the PHQ-9 scale was used, with a score below five indicating remission of illness. Significant clinical improvement that does not constitute remission is termed response, and is graded by a 50% or greater reduction of score from baseline on the HAMD and MADRS scales, and a score of one, two or three on the CGI-S or a score below 10 on the PHQ-9. Outcomes are also reported for each of these rating scales as a mean change in total score from baseline, called continuous outcome measures. Standardized effect size measures are used to assess the statistical magnitude of treatment benefit (active versus control) in a clinical trial, and because they are normalized measures, allow the comparison of treatment benefit across different clinical studies. Standardized effect sizes of greater than 0.50 are considered large, between 0.30 and 0.50 are considered medium and below 0.30 are considered small.

Randomized Controlled Trial

Our U.S. registration trial was a prospective, multisite, randomized, sham-controlled trial at 23 U.S. and international study sites that enrolled 325 patients from January 2004 through August 2005 to evaluate the safety and efficacy of NeuroStar Advanced Therapy in patients who met DSM-IV criteria for MDD, with a moderate level of treatment resistance based on rigorous evidence of failure of benefit from prior treatment with a research-grade exposure to at least one and up to four complete antidepressant medication trials. Patients were randomized to either active NeuroStar Advanced Therapy or sham-controlled TMS. The primary efficacy endpoint of this trial was a statistically significant, or P<0.05, average baseline to endpoint change in MADRS score for patients in the active NeuroStar Advanced Therapy treatment group when compared to the change in MADRS score for the sham-controlled TMS patient treatment group using the last visit MADRS score through week four of the acute phase. The trial design consisted of three phases: a one week, no-treatment lead-in phase; a six week acute treatment phase of daily TMS sessions scheduled in a 5-day sequence, for a maximum of 30 sessions during which NeuroStar Advanced Therapy was given in the active treatment arm as a monotherapy in medication-free patients, and a three week taper phase during which time all patients were begun on an open-label, single antidepressant medication and followed for six months to examine the durability of the acute effect of TMS.

20

Results for the overall trial population demonstrated clinically meaningful improvement on the primary efficacy outcome measure, baseline to endpoint change on the MADRS at four weeks, as shown in Figure 2 (MADRS, P=0.057, standardized effect size = 0.38), although the primary efficacy endpoint of the trial was not achieved. Additionally, several secondary outcome measures demonstrated statistically and clinically significant benefit for active NeuroStar Advanced Therapy compared with sham-controlled TMS. Among these secondary outcome measures were a superior outcome on the HAMD, with both the 17 and 24-item versions showing baseline to endpoint change for active NeuroStar Advanced Therapy at four weeks, as shown in Figure 3 (17-Item change: P=0.006, standardized effect size = 0.55) and as shown in Figure 4 (24-Item change: P=0.012, standardized effect size = 0.48). These outcomes were sustained at the secondary efficacy time point at week six, with a significant advantage in favor of active NeuroStar Advanced Therapy.

We also observed a statistically significant benefit in categorical outcomes of response and remission rates on the MADRS, as shown in Figure 5, the HAMD17, as shown in Figure 6, and the HAMD24, as shown in Figure 7. In this trial, NeuroStar Advanced Therapy was well tolerated and safe. The dropout rate for any reason was low and similar in the active therapy (7.7%) and sham-controlled TMS (8.2%) treatment groups at four weeks, and discontinuation specifically because of side effects was similar in the active therapy (4.5%) and sham-controlled TMS (3.4%) treatment groups. The trial demonstrated that NeuroStar Advanced Therapy administered over a period of six weeks was effective in treating MDD and with a favorable tolerability profile.

21

Our NeuroStar Advanced Therapy System received marketing authorization from the FDA in 2008 based on the results of this initial registration trial. The FDA review determined that statistical significance for the primary outcome measure was obtained for the patients in that portion of the study population (N=164) who had failed to benefit from one prior research grade antidepressant medication treatment trial (MADRS, P=0.0006). The original FDA-authorized indication for use in MDD based on this trial was for adult patients who failed to benefit from one prior antidepressant medication in the current episode.

NIMH-Sponsored Randomized Controlled Trial—the Optimization of TMS, or OPT-TMS Study

The U.S. NIMH sponsored a prospective, multisite, randomized, sham-controlled trial at four U.S. study sites that enrolled 199 patients from October 2004 through March 2009 to evaluate the safety and efficacy of NeuroStar Advanced Therapy in patients who met DSM-IV criteria for MDD, with at least a moderate level of treatment resistance to at least one and up to four complete antidepressant medication trials. Patients were randomly allocated 1:1 to either active NeuroStar Advanced Therapy or sham-controlled TMS. The primary efficacy endpoint of this trial was remission, measured using the 24-item HAMD scale. The trial design consisted of three phases: a two week no treatment lead-in phase, a three-week fixed-treatment phase of daily TMS sessions scheduled in a 5-day sequence, for a maximum of 15 sessions during which NeuroStar Advanced Therapy was given in the active treatment arm as a monotherapy in antidepressant medication-free patients and a variable, three-week treatment continuation for clinical improvers.

Results from the trial demonstrated that for the entire treatment resistant patient population, for the primary analysis of remission, there was a statistically significant effect of daily NeuroStar Advanced Therapy as monotherapy (odds ratio, 4.2; 95% confidence interval, 1.32–13.24; P=0.02). There were 18 remitters (N=13 or 14.1% in the active therapy and N=5 or 5.1% in the sham-controlled TMS treatment groups). NeuroStar Advanced Therapy was well tolerated, with no difference in adverse events between the active therapy and sham-controlled TMS treatment groups. Discontinuation specifically because of side effects was 5.4% in the active therapy treatment group. These results indicate that the likelihood of achieving remission using the NeuroStar Advanced Therapy System increased by more than four times when compared to sham-control TMS, which is clinically meaningful.

The results of this clinical trial became available after we received our original marketing authorization in 2008. We submitted the clinical data from this trial to the FDA and received a new FDA 510(k) clearance in 2014 that expanded our original indication to adult patients who have failed to benefit from one or more prior antidepressant medications in the current episode of MDD.

Acute Efficacy and Long-Term Durability in Real-World Clinical Settings Study

The acute efficacy of treatment with the NeuroStar Advanced Therapy System was evaluated in a prospective, multisite, naturalistic, observational trial at 42 U.S. study sites that enrolled 307 patients from 2010 through 2012 to evaluate the effectiveness of NeuroStar Advanced Therapy in real-world clinical practice settings in patients who met DSM-IV criteria for MDD. The mean patient age was 48.6 years and the mean number of medication trials in the current episode that were of adequate dose and duration was 2.5, indicating a treatment resistant population of patients with MDD. Outcome assessments were obtained at baseline, week two, at the point of maximal acute treatment benefit and at week six in cases where the acute course of TMS therapy extended beyond six weeks. This naturalistic study design permitted patients to continue concurrent antidepressant medications during treatment with NeuroStar Advanced Therapy if they were directed to do so by the prescribing psychiatrist. The primary efficacy endpoint of this trial was the change from baseline to endpoint on the CGI-S. Secondary outcome measures included baseline to endpoint change on the PHQ-9.

The average number of NeuroStar Advanced Therapy treatment sessions across the acute phase was 28.3 (standard deviation: 10.1). Results from the trial demonstrated that there was a statistically significant mean change in depression severity from baseline to end of treatment on the CGI-S (-1.9 ± 1.4, P<0.0001) and for the PHQ-9 (-8.7 ± 7.2, P<0.0001). Clinician-assessed response rate for CGI-S was 58.0% and the remission rate was 37.1%, as shown in Figure 8. Patient-reported outcomes measured using the PHQ-9 was 56.4% for response, and 28.7% for remission, as shown in Figure 9. Notably, the outcomes were consistent across patients with both low and high grades of treatment resistance. Patients with low treatment resistance had been treated without success with one antidepressant medication in their current illness episode and patients with high grades of treatment resistance had been treated with two or more antidepressants without benefit. These results further support NeuroStar Advanced Therapy as an effective therapy for those who have failed to benefit from antidepressant medication.

The long-term durability of the clinical effect resulting from treatment with NeuroStar Advanced Therapy was also studied as part of this report over 12 months of follow-up. In the long-term phase, 257 patients who had participated in the acute treatment outcomes entered into long-term follow-up where their treatment outcomes were monitored over the next twelve months. This trial was conducted between March 2010 and August 2012. Clinical assessments using the CGI-S and the PHQ-9 were obtained at three, six, nine, and 12 months. A total of 205 patients provided data across the entire12-month trial period. Concurrent medication use and NeuroStar Advanced Therapy reintroduction were allowed for recurrent symptoms and were recorded during the long-term follow-up period.

23

Compared with baseline scores obtained prior to acute TMS treatment, the statistically significant reduction in mean standard deviation CGI-S and PHQ-9 total scores at the end of acute TMS treatment were sustained throughout the 12-month follow-up period (end of 12 months follow-up: CGI-S 2.8 and PHQ-9 8.6, both P<0.0001). The proportion of patients who achieved remission at the conclusion of acute TMS treatment remained similar to that observed following the conclusion of the long-term follow-up phase: CGI-S (total score 1 or 2), 41.2% (end of acute) and 45.1% (end of long-term), as shown in Figure 10; PHQ-9 (total score < 5), 31.1% (end of acute) and 37.0% (end of long-term). These results demonstrate that NeuroStar Advanced Therapy provides a sustained durability of effect over 12 months of follow-up in a patient population receiving minimal to no benefit with antidepressant medications.

Our Outcome Registry

In 2016, we launched our voluntary outcome registry to measure and record the outcomes of MDD patients treated with our NeuroStar Advanced Therapy System. Since inception, we have recorded results for over 1,500 patients at approximately 50 treatment facilities. For the patients treated with our products who completed self-evaluations, such as PHQ-9, and have had their results submitted to the registry, our data indicates remission and response rates of 32% and 62%, respectively. For the more than 600 patients treated with our products who have been evaluated using an observer-dependent interview, such as CGI-S, and have had their results submitted to the registry, our data indicates remission and response rates of 53% and 75%, respectively. Although we believe that these results demonstrate the potential of our products to treat patients with MDD, our registry is voluntary and only a portion of psychiatrists using our products have reported their outcomes. Therefore, these results may not be representative of response and remission rates for all MDD patients treated with our products.

Sales and Customer Support Team and Psychiatrist Training

As of December 31, 2018, our sales and customer support team consisted of 133 employees working collaboratively across the following departments: 96 sales, 6 marketing, 22 field service and customer support, and 9 reimbursement. Additionally, our clinical team consisted of 7 employees.

Sales and Marketing—United States

Our commercialization team selectively markets and sells the NeuroStar Advanced Therapy System and recurring treatment sessions in the United States. Our primary focus is on selling to psychiatrists, with primary care physicians and pain management specialists representing a small percentage of our customer base. We target approximately 3,600 high-decile psychiatric practices, who we estimate, based on data from Symphony Health and our own internal estimates, treat approximately 33% of MDD patients who meet our labeled indication and are insured. We target these practices by the number of psychiatrists within their practices, the number of patients they treat and their acceptance of commercial insurance and Medicare. We believe that our psychiatrist targeting strategy makes for a well-defined customer base that is accessible by our direct sales organization.

We have structured our sales and customer support team with specialized roles to sell our NeuroStar Advanced Therapy Systems and recurring treatment sessions, while delivering customer service at each stage of the implementation process. Our business development managers are responsible for identifying key customer prospects, educating them on the value of NeuroStar Advanced Therapy System, gaining their commitment for capital placement and introducing our clinical practice consultants. Our clinical practice consultants enhance the operational experience for providers and drive implementation of the NeuroStar Advanced Therapy System into our customers’ practices. We created the role of clinical training consultant to partner with our psychiatrist providers to conduct initial and ongoing on-site clinical training to ensure clinical and practice success.

24

Practice Management Support and Psychiatrist Training—United States

Our clinical practice consultants play a pivotal role in ensuring the success of our customers as they implement a new service line into their practice. In the early stages of implementation, they help the practice set goals, educate on the types of patients that can benefit from our therapy and assist in preparing the office work flow and staffing needs. As the office prepares to begin scheduling consults, the clinical practice consultants will train the office staff on how to talk with patients about TMS and how to use patient educational tools such as presentations, videos and starter kits. Once the practice begins treating patients, they will educate the psychiatrist on how to track clinical outcomes, interpret data and how to effectively convey results to existing and potential patients and referring physicians. Our clinical practice consultants also work with our customers to increase awareness with referring physicians and develop external marketing tactics. Our dedicated reimbursement managers help each practice navigate all issues regarding the reimbursement process including investigation of benefits, prior authorizations and claims documentation. This group has assisted our customers to conduct over 31,000 benefit investigations.

Psychiatrists and staff training on the NeuroStar Advanced Therapy System is a key to success within each practice. Our clinical training consultants take the burden of clinical training off our clinical practice consultants and provide a dedicated training resource to each customer. Clinical training consultants conduct at least a three-day, hands on training course that is scheduled after system installation at each practice and also provide ongoing advanced on-site clinical training.

Field Support—United States

Our field service engineers are responsible for maintenance, repairs and installation of upgrades. We provide a 24/7 support hotline to respond to medical information inquiries and technical questions that arise in all time zones. We pledge to have a field service engineer on-site within 24 hours of a service call. Because of the size and geographical coverage of our field service engineers and our standard 24-hour response time, NeuroStar Advanced Therapy Systems experience over 99% uptime, helping to ensure uninterrupted patient treatments.

International

We market our products in a few select markets outside the United States through independent distributors. In Japan, we have an exclusive distribution agreement with Teijin, for the commercialization of our products.

Distribution Agreement with Teijin Pharma Limited

In October 2017, we entered into a seven and a half year distribution agreement with Teijin Pharma Limited, or Teijin, for the exclusive distribution of our NeuroStar Advanced Therapy System to customers who will treat patients with MDD in Japan. Under the distribution agreement, Teijin is generally restricted from selling competing products in Japan. Our distribution agreement provides that we will have primary responsibility for obtaining reimbursement approval for use of NeuroStar Advanced Therapy System for the treatment of MDD in Japan, and Teijin will promote the sales of NeuroStar Advanced Therapy System for treatment of MDD in Japan. We have agreed to provide sales and technical support training to Teijin for our NeuroStar Advanced Therapy Systems.

Teijin is required to purchase minimum dollar values of NeuroStar Advanced Therapy Systems and treatment sessions from us following reimbursement approval by the JMHLW, TMS treatment for MDD (or, if such approval requires certified training on the NeuroStar Advanced Therapy System by a third party, then upon the first psychiatrist being issued his or her training certification). In April 2018, we were approved to submit reimbursement dossiers to the JMHLW.

In 2017, under our distribution agreement with Teijin, we received an upfront payment of $0.75 million and a milestone payment of $2.0 million following JMHLW’s approval of marketing the NeuroStar Advanced Therapy System for the treatment of MDD in Japan. These upfront and milestone payments have been deferred and are being recognized as revenue over the seven and one half year term of the agreement. Teijin is required to pay us a milestone payment tied to JMHLW issuing reimbursement for use of our products for the treatment of MDD in Japan.

25

The distribution agreement is scheduled to expire on March 31, 2025, subject to earlier termination if we or Teijin breach the agreement, Teijin fails to maintain distributor-level permits and approvals, Teijin fails to purchase from us specified dollar values of its sales forecasts, reimbursement for treatment of MDD using the NeuroStar Advanced Therapy System is not obtained from JMHLW by specified dates or such reimbursement is below specified minimums, Teijin reasonably believes that it is not commercially reasonable to continue distributing the NeuroStar Advanced Therapy System in Japan or bankruptcy related events occur. The term of the distribution agreement will be automatically extended for two years unless either party gives the other party at least two years’ prior written of notice of non-renewal, except that we cannot decline to renew the agreement if Teijin has purchased 100% of its sales forecasts over the term of the agreement.

Competition

Our currently marketed products are, and any future products we develop and commercialize will be, subject to intense competition. The industry in which we operate is subject to rapid change and is highly sensitive to the introduction of new products or other market activities of current or new industry participants. If we are not successful in convincing others of the merits of our products or educating them on the use of our products, they may not use our products or use them effectively and we may be unable to increase our sales. Key competitive factors affecting the commercial success of the NeuroStar Advanced Therapy System and any other product candidates we may develop are likely to be efficacy, safety and tolerability profile, reliability, convenience of administration, price, treatment times, other indications outside of MDD and reimbursement.

We have competitors that sell other forms of TMS therapy, including Brainsway, Magstim, MagVenture, CloudTMS and Nexstim, that compete directly with the NeuroStar Advanced Therapy System and have TMS therapy treatment times as short as 20, 37, three, 19 and 37 minutes, respectively. Competing TMS therapy companies have developed and may develop additional treatments that can be administered for shorter time periods or for indications outside of MDD, or may develop treatments that have improved efficacy when compared to our products or that require a less significant investment of resources from psychiatrists. We also face competition from pharmaceutical and other companies that develop products, such as antidepressant medications, for the treatment of psychiatric disorders. Our commercial opportunity could be reduced or eliminated if these competitors develop and commercialize antidepressant medications or other treatments that are safer, more convenient or more effective than the NeuroStar Advanced Therapy System. At any time, these and other potential market entrants may develop treatment alternatives that may render our products uncompetitive.

In addition, our competitors may have greater financial resources or more established distribution networks than we do, or may be acquired by enterprises that have more established distribution networks than we do. Our competitors may also develop and patent processes or products earlier than we can or obtain domestic or international regulatory clearances or approvals for competing products more rapidly than we can, which could impair our ability to develop and commercialize similar products. We also compete with our competitors in acquiring technologies and technology licenses complementary to our products or advantageous to our business. In addition, we compete with our competitors to engage the services of independent distributors outside the United States, both those presently working with us and those with whom we hope to work as we expand.

Intellectual Property

Our commercial success depends in part on our ability to obtain and maintain proprietary protection for our products and services, to operate without infringing the proprietary rights of others, and to prevent others from infringing our proprietary rights. We rely on a combination of patents, trade secrets, copyrights and trademarks, as well as contractual protections, to establish and protect our intellectual property rights. We seek to protect our proprietary position by, among other things, filing patent applications in the United States and internationally. Our patent estate includes patents and applications with claims directed to our NeuroStar Advanced Therapy Systems and broader claims for potential future products and developments. On a worldwide basis, as of December 31, 2018, our patent estate included over 100 issued or allowed patents and pending patent applications for our products and novel design methods, manufacturing process, novel TMS devices and systems and future combination products that are mainly designed to treat psychiatric conditions or perform diagnostic procedures. In the United States, as of December 31, 2018, we owned or licensed 34 issued or allowed patents and eight patent applications filed that are directed to our TMS technology. Outside the United States, as of December 31, 2018, we owned or licensed 49 issued or allowed patents, 11 pending patent applications and one pending Patent Cooperation Treaty application.

26

These U.S. issued patents are expected to remain in effect until between 2019 and 2035. Our core patents in the United States will not expire before 2024. Our non-U.S. patents are expected to remain in effect until between 2024 and 2035. Our worldwide intellectual property portfolio includes multiple pending patent applications relating to methods and apparatuses for the treatment of psychiatric health conditions in Australia, Canada, the European Union, Japan and the United States. Our patents and patent applications mainly relate to iron core technology, including materials, manufacturing methods, geometries, applications, and open core technologies, TMS design patents, including coil position, motor threshold level determination, contact sensing, and articulation arm designs, patient comfort, TMS support technologies and pulse monitoring, and potential next generation technologies.

In some instances, we submit patent applications directly with the USPTO as provisional patent applications. Provisional applications for patents were designed to provide a lower-cost first patent filing in the United States. Corresponding non-provisional patent applications must be filed not later than 12 months after the provisional application filing date. The corresponding non-provisional application benefits in that the priority date(s) of the patent application is/are the earlier provisional application filing date(s), and the patent term of the finally issued patent is calculated from the later non-provisional application filing date. This system allows us to obtain an early priority date, add material to the patent application(s) during the priority year, obtain a later start to the patent term and to delay prosecution costs, which may be useful in the event that we decide not to pursue examination in an application. We file U.S. non-provisional applications and Patent Cooperation Treaty, or PCT, applications that claim the benefit of the priority date of earlier filed provisional applications, when applicable. The PCT system allows a single application to be filed within 12 months of the original priority date of the patent application, and to designate all of the 152 PCT member states in which national patent applications can later be pursued based on the international patent application filed under the PCT. The PCT searching authority performs a patentability search and issues a non-binding patentability opinion which can be used to evaluate the chances of success for the national applications in foreign countries prior to having to incur the filing fees. Although a PCT application does not issue as a patent, it allows the applicant to seek protection in any of the member states through national-phase applications.

At the end of the period of two and a half years from the first priority date of the patent application, separate patent applications can be pursued in any of the PCT member states either by direct national filing or, in some cases by filing through a regional patent organization, such as the European Patent Organization. The PCT system delays expenses, allows a limited evaluation of the chances of success for national/regional patent applications and enables substantial savings where applications are abandoned within the first two and a half years of filing.

For all patent applications, we determine claiming strategy on a case-by-case basis. Advice of counsel and our business model and needs are always considered. We file patents containing claims for protection of all useful applications of our proprietary technologies and any products, as well as all new applications and/or uses we discover for existing technologies and products, assuming these are strategically valuable. We continuously reassess the number and type of patent applications, as well as the pending and issued patent claims to ensure that maximum coverage and value are obtained for our processes, and compositions, given existing patent office rules and regulations. Further, claims may be modified during patent prosecution to meet our intellectual property and business needs.

We recognize that the ability to obtain patent protection and the degree of such protection depends on a number of factors, including the extent of the prior art, the novelty and non-obviousness of the invention, and the ability to satisfy the enablement requirement of the patent laws. The patent positions of medical device companies like ours are generally uncertain and involve complex legal, scientific and factual questions. In addition, the coverage claimed in a patent application can be significantly reduced before the patent is issued, and its scope can be reinterpreted or further altered even after patent issuance. Consequently, we may not obtain or maintain adequate patent protection for any of our product candidates or for our technology platform. We cannot predict whether the patent applications we are currently pursuing will issue as patents in any particular jurisdiction or whether the claims of any issued patents will provide sufficient proprietary protection from competitors. Any patents that we hold may be challenged, circumvented or invalidated by third parties.

Our commercial success will also depend in part on not infringing the proprietary rights of third parties. In addition, we have licensed rights under proprietary technologies of third parties to develop, manufacture and commercialize specific aspects of our products and services. It is uncertain whether the issuance of any third party patent would

27

require us to alter our development or commercial strategies, alter our processes, obtain licenses or cease certain activities. The expiration of patents or patent applications licensed from third parties or our breach of any license agreements or failure to obtain a license to proprietary rights that we may require to develop or commercialize our future technology may have a material adverse impact on us. If third parties prepare and file patent applications in the United States that also claim technology to which we have rights, we may have to participate in interference proceedings in the USPTO to determine priority of invention.

We further own trade secrets relating to our technology, and we maintain the confidentiality of proprietary information to protect aspects of our business that are not amenable to, or that we do not consider appropriate for, patent protection. We seek to protect our trade secrets and know-how by entering into confidentiality agreements with third-parties, consultants and employees who have access to such trade secrets and know-how. These agreements provide that all confidential information concerning our business or financial affairs developed or made known to the individual during the course of the individual’s relationship with us are to be kept confidential and not disclosed to third parties except in specific circumstances. In addition, we enter into employment agreements that require employees to assign to us any inventions, trade secrets or know-how that they develop while employed by us. Although we take steps to protect our proprietary information and trade secrets, including through agreements with our employees and consultants, these agreements may be breached, or third parties may independently develop substantially equivalent proprietary information and techniques or otherwise gain access to our trade secrets or disclose our technology. Thus, we may not be able to meaningfully protect our trade secrets. To the extent that our employees, consultants, scientific advisors or other contractors use intellectual property owned by others in their work for us, disputes may arise as to the rights in related or resulting know how and inventions.

For a more comprehensive discussion of the risks related to our intellectual property, please see “Risk Factors—Risks Related to Intellectual Property.”

Manufacturing and Supply

We manage all aspects of product supply through our operations team based in Malvern, Pennsylvania. We outsource the manufacture of components and high level assemblies, which are produced and tested to our specifications. We rely on third party providers to provide components used in existing products and we expect to continue to do so for future products.

We manage our arrangements with our third-party manufacturers and suppliers to adjust delivery schedules and quantities of components to match our changing manufacturing requirements. We forecast our component needs based on historical trends, current utilization patterns and sales forecasts of future demand. We establish our relationships with our third-party manufacturers and suppliers through supplier contracts and purchase orders. In most cases, these supplier relationships may be terminated by either party upon short notice. Currently, we are engaged with Sparton Medical Systems to supply our console; Molex Incorporated to supply our SenStar Treatment Link; Paragon Micro to supply our computer systems as well as other companies to supply components of our chairs and treatment packs.

In order to mitigate against the risks related to a single-source of supply, we qualify alternative suppliers when possible, maximize the use of commercial, off the shelf components and materials, minimize specialized or proprietary manufacturing processes, and develop contingency plans for responding to disruptions, including maintaining adequate inventory of any critical components. To date, we have not experienced material delays in obtaining any of our components, nor has the ready supply of finished products to our customers or clinicians been adversely affected by component supply issues.

Reimbursement, Payor Relations and Customer Support

Coverage and Reimbursement in the United States

Sales of a medical device, which is utilized for in-office medical treatments, depends, in part, on the extent to which such treatments using that medical device will be covered by third-party payors, such as government health care programs, including Medicare and Medicaid private insurance and managed healthcare organizations. Even if a third-party payor covers a particular treatment, the resulting reimbursement payment rates may not be adequate to

28

cover a provider’s cost to purchase such medical device or ensure that purchase will be profitable for the provider. Additionally, patients who are treated in-office for a medical condition generally rely on third-party payors to reimburse all or part of the costs associated with the treatment and may be unwilling to undergo such treatment in the absence of coverage and adequate reimbursement.

Reimbursement by a third-party payor may depend upon a number of factors, including the third-party payor’s determination that a treatment is neither experimental nor investigational; safe, effective, and medically necessary; appropriate for the specific patient; cost-effective; supported by peer reviewed medical journals; and included in clinical practice guidelines.

In the United States, there is no uniform policy of coverage and reimbursement among third-party payors. Third-party payors often rely upon Medicare coverage policy and payment limitations in setting their own reimbursement policies, but also have their own methods and approval process apart from Medicare coverage and reimbursement determinations. Therefore, coverage and reimbursement for treatments can differ significantly from payor to payor. Decisions regarding the extent of coverage and amount of reimbursement to be provided for an in-office treatment are made on a plan-by-plan basis. One payor’s determination to provide coverage for a specific treatment does not assure that other payors will also provide coverage, and adequate reimbursement.

In addition, the federal government and state legislatures have continued to implement cost containment programs, including price controls and restrictions on coverage and reimbursement. Third-party payors are increasingly challenging the price, examining the medical necessity and reviewing the cost effectiveness of medical services. Adoption of price controls and cost containment measures, and adoption of more restrictive policies in jurisdictions with existing controls and measures, could further limit our net sales and results of operations.

Based on our estimates, over 65 major private insurers in the United States, including the top 25 largest private insurers, have coverage policies for reimbursement of NeuroStar Advanced Therapy, representing approximately 205 million covered lives or about 95% of the total payor covered lives in the United States. Treatments using NeuroStar Advanced Therapy are also eligible for reimbursement from Medicare, representing an additional 59 million covered lives in the United States as of January 2018.

Government Regulation

Our products and our operations are subject to extensive regulation by the FDA and other federal and state authorities in the United States, as well as comparable authorities in foreign jurisdictions. Our products are subject to regulation as medical devices under the FDCA, as implemented and enforced by the FDA. The FDA regulates the development, design, non-clinical and clinical research, manufacturing, safety, efficacy, labeling, packaging, storage, installation, servicing, recordkeeping, premarket clearance or approval, import, export, adverse event reporting, advertising, promotion, marketing and distribution, and import and export of medical devices to ensure that medical devices distributed domestically are safe and effective for their intended uses and otherwise meet the requirements of the FDCA.

In addition to U.S. regulations, we are subject to a variety of regulations in other jurisdictions governing clinical trials and commercial sales and distribution of our products. Whether or not we obtain FDA clearance or approval for a product, we must obtain authorization before commencing clinical trials or obtain marketing authorization or approval of our products under the comparable regulatory authorities of countries outside of the United States. The marketing authorization process varies from country to country and the time may be longer or shorter than that required for FDA clearance or approval.

FDA Premarket Clearance and Approval Requirements

Unless an exemption applies, each medical device commercially distributed in the United States requires either FDA clearance of a 510(k) premarket notification or PMA approval. Under the FDCA, medical devices are classified into one of three classes—Class I, Class II or Class III—depending on the degree of risk associated with each medical device and the extent of manufacturer and regulatory control needed to ensure its safety and efficacy. Class I includes devices with the lowest risk to the patient and are those for which safety and efficacy can be assured by adherence to the FDA’s General Controls for medical devices, which include compliance with the applicable

29

portions of the quality systems regulation, or QSR, facility registration and product listing, reporting of adverse medical events, and truthful and non-misleading labeling, advertising, and promotional materials. Class II devices are subject to the FDA’s General Controls, and special controls as deemed necessary by the FDA to ensure the safety and efficacy of the device. These special controls can include performance standards, post-market surveillance, patient registries and FDA guidance documents. While most Class I devices are exempt from the 510(k) premarket notification requirement, manufacturers of most Class II devices are required to submit to the FDA a premarket notification under Section 510(k) of the FDCA requesting permission to commercially distribute the device. The FDA’s permission to commercially distribute a device subject to a 510(k) premarket notification is generally known as 510(k) clearance. Devices deemed by the FDA to pose the greatest risks, such as life-sustaining, life-supporting or some implantable devices, or devices that have a new intended use, or use advanced technology that is not substantially equivalent to that of a legally marketed device, are placed in Class III, requiring approval of a PMA.

Our NeuroStar Advanced Therapy System is classified as a Class II medical device. We initially received marketing authorization of this device through the de novo classification process. Subsequently, we have cleared any changes made to our system through the 510(k) clearance process.

510(k) Marketing Clearance Pathway

To obtain 510(k) clearance, we must submit to the FDA a premarket notification submission demonstrating that the proposed device is “substantially equivalent” to a predicate device already on the market. A predicate device is a legally marketed device that is not subject to premarket approval, i.e., a device that was legally marketed prior to May 28, 1976 (pre-amendments device) and for which a PMA is not required, a device that has been reclassified from Class III to Class II or I, or a device that was found substantially equivalent through the 510(k) process. The FDA’s 510(k) clearance process usually takes from nine to twelve months, but may take significantly longer. The FDA may require additional information, including clinical data, to make a determination regarding substantial equivalence. If the FDA agrees that the device is substantially equivalent to a predicate device currently on the market, it will grant 510(k) clearance to commercially market the device. If the FDA determines that the device is “not substantially equivalent” to a previously cleared device, the device is automatically designated as a Class III device. The device sponsor must then fulfill more rigorous PMA requirements, or can request a risk-based classification determination for the device in accordance with the “de novo” process, which is a route to market for novel medical devices that are low to moderate risk and are not substantially equivalent to a predicate device.

Pre-Market Approval Process

A PMA application must be submitted if the medical device is in Class III (although the FDA has the discretion to continue to allow certain pre-amendment Class III devices to use the 510(k) process) or cannot be cleared through the 510(k) process. A PMA application must be supported by, among other things, extensive technical, preclinical, clinical trials, manufacturing and labeling data to demonstrate to the FDA’s satisfaction the safety and effectiveness of the device.

After a PMA application is submitted and filed, the FDA begins an in-depth review of the submitted information, which typically takes between one and three years, but may take significantly longer. During this review period, the FDA may request additional information or clarification of information already provided. Also during the review period, an advisory panel of experts from outside the FDA will usually be convened to review and evaluate the application and provide recommendations to the FDA as to the approvability of the device. In addition, the FDA will conduct a pre-approval inspection of the manufacturing facility to ensure compliance with the QSR, which imposes elaborate design development, testing, control, documentation and other quality assurance procedures in the design and manufacturing process. The FDA may approve a PMA application with post-approval conditions intended to ensure the safety and effectiveness of the device including, among other things, restrictions on labeling, promotion, sale and distribution and collection of long-term follow-up data from patients in the clinical study that supported approval. Failure to comply with the conditions of approval can result in materially adverse enforcement action, including the loss or withdrawal of the approval. New PMA applications or supplements are required for significant modifications to the manufacturing process, labeling of the product and design of a device that is approved through the PMA process. PMA supplements often require submission of the same type of information as an original PMA application, except that the supplement is limited to information needed to support any changes from the device covered by the original PMA application, and may not require as extensive clinical data or the convening of an advisory panel.

30

De novo Classification Process

Medical device types that the FDA has not previously classified as Class I, II, or III are automatically classified as Class III regardless of the level of risk they pose. The Food and Drug Administration Modernization Act of 1997 established a new route to market for low to moderate risk medical devices that are automatically placed into Class III due to the absence of a predicate device, called the “Request for Evaluation of Automatic Class III Designation,” or the de novo classification procedure. This procedure allows a manufacturer whose novel device is automatically classified as Class III to request down-classification of its medical device into Class I or Class II on the basis that the device presents low or moderate risk, rather than requiring the submission and approval of a PMA application. Prior to the enactment of the Food and Drug Administration Safety and Innovation Act, or FDASIA, in July 2012, a medical device could only be eligible for de novo classification if the manufacturer first submitted a 510(k) premarket notification and received a determination from the FDA that the device was not substantially equivalent. FDASIA streamlined the de novo classification pathway by permitting manufacturers to request de novo classification directly without first submitting a 510(k) premarket notification to the FDA and receiving a not substantially equivalent determination. We originally obtained marketing authorization for our system using the de novo classification process after receiving a not substantially equivalent determination following the submission of a 510(k) premarket notification. We have subsequently used the 510(k) clearance process to obtain authorization from the FDA for changes to our marketed system.

Clinical Trials

A clinical trial is typically required to support a PMA application or de novo classification, and is sometimes required for a 510(k) pre-market notification. Clinical trials generally require submission of an application for an Investigational Device Exemption, or IDE, to the FDA. The IDE application must be supported by appropriate data, such as animal and laboratory testing results, showing that it is safe to test the device in humans and that the investigational protocol is scientifically sound. The IDE application must be approved in advance by the FDA for a specified number of patients, unless the product is deemed a non-significant risk device and eligible for more abbreviated IDE requirements. Clinical trials for a significant risk device may begin once the IDE application is approved by the FDA as well as the appropriate institutional review boards, or IRBs, at the clinical trial sites, and the informed consent of the patients participating in the clinical trial is obtained. After a trial begins, the FDA may place it on hold or terminate it if, among other reasons, it concludes that the clinical subjects are exposed to an unacceptable health risk. Any trials we conduct must be conducted in accordance with FDA regulations as well as other federal regulations and state laws concerning human subject protection and privacy. Moreover, the results of a clinical trial may not be sufficient to obtain clearance or approval of the product.

Changes to Marketed Devices

After a device receives 510(k) marketing clearance, or de novo classification, any modification that could significantly affect its safety or efficacy, or that would constitute a major change or modification in its intended use, will require a new 510(k) marketing clearance or, depending on the modification, a de novo classification or PMA approval. The FDA requires each manufacturer to determine whether the proposed change requires submission of a 510(k) or a PMA in the first instance, but the FDA can review any such decision and disagree with a manufacturer’s determination. Many minor modifications today are accomplished by a manufacturer documenting the change in an internal letter-to-file. The letter-to-file is in lieu of submitting a new 510(k) to obtain clearance for every change. The FDA can always review these letters to file in an inspection. If the FDA disagrees with a manufacturer’s determination, the FDA can require the manufacturer to cease marketing and/or request the recall of the modified device until 510(k) marketing clearance or PMA approval is obtained. Also, in these circumstances, we may be subject to significant regulatory fines or penalties.

31

Post-Market Regulation

After a device is cleared or approved for marketing, numerous and pervasive regulatory requirements continue to apply. These include:

We may be subject to similar foreign laws that may include applicable post-marketing requirements such as safety surveillance and risk-benefit analysis. Our manufacturing processes are required to comply with the applicable portions of the QSR, which cover the methods and the facilities and controls for the design, manufacture, testing, production, processes, controls, quality assurance, labeling, packaging, distribution, installation and servicing of finished devices intended for human use. The QSR also requires, among other things, maintenance of a device master file, device history file, and complaint files. As a manufacturer, we are subject to periodic scheduled or unscheduled inspections by the FDA. Our failure to maintain compliance with the QSR requirements could result in the shut-down of, or restrictions on, our manufacturing operations and the recall or seizure of our products. The discovery of previously unknown problems with any of our products, including unanticipated adverse events or adverse events of increasing severity or frequency, whether resulting from the use of the device within the scope of its clearance or off-label by a physician in the practice of medicine, could result in restrictions on the device, including the removal of the product from the market or voluntary or mandatory device recalls.

The FDA has broad regulatory compliance and enforcement powers. If the FDA determines that we failed to comply with applicable regulatory requirements, it can take a variety of compliance or enforcement actions, which may result in any of the following sanctions:

32

U.S. and Foreign Healthcare Laws and Compliance Requirements

Healthcare providers, physicians and third-party payors play a primary role in the recommendation, prescription and payment for medical treatments. A medical device manufacturer’s arrangements with third-party payors, providers and patients may expose it to broadly applicable fraud and abuse and other healthcare laws and regulations that may affect its business or the financial arrangements and relationships through which it markets, sells and distributes its products. Even if a medical device manufacturer does not control referrals of healthcare services or bill directly to Medicare, Medicaid or other third-party payors, federal and state healthcare laws and regulations are applicable to its business. In addition, a portion of our business is subject to the Health Insurance Portability and Accountability Act of 1996, or HIPAA, as a business associate of our covered entity customers. To provide our covered entity customers with services that involve the use or disclosure of PHI, we are required to enter into business associate agreements. As a business associate, we are also directly liable for compliance with HIPAA. The laws that may affect a medical device manufacturer’s ability to operate include, but are not limited to:

33

Because of the breadth of these laws and the narrowness of their statutory exceptions and regulatory safe harbors, it is possible that some of a medical device manufacturer’s business activities could be subject to challenge under one or more of these laws. The scope and enforcement of each of these laws is uncertain and subject to rapid change in the current environment of healthcare reform, especially in light of the lack of applicable precedent and regulations. Federal and state enforcement bodies have recently increased their 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.

Ensuring that business arrangements with third parties comply with applicable healthcare laws and regulations is costly and time consuming. If a medical device manufacturer’s operations are found to be in violation of any of the laws described above or any other governmental regulations that apply to it, it may be subject to penalties, including civil, criminal and administrative penalties, damages, fines, disgorgement, individual imprisonment, exclusion from governmental funded healthcare programs, such as Medicare and Medicaid, additional reporting obligations and oversight if it becomes subject to a corporate integrity agreement or other agreement to resolve allegations of non-compliance with these laws, reputational harm, diminished profits and future earnings, and the curtailment or restructuring of operations, any of which could adversely affect the ability of a medical device manufacturer to operate its business and the results of its operations.

34

United States Healthcare Reform

In the United States, a number of legislative and regulatory proposals have been considered or enacted to change the healthcare system in ways that could affect a medical device manufacturer’s business. Among policy makers and payors in the United States, there is significant interest in promoting changes in healthcare systems with the stated goals of containing healthcare costs, improving quality or expanding access. For example, in 2010, the PPACA was enacted, which includes measures to significantly change the way health care is financed by both governmental and private insurers, and significantly impacts the medical device industry. Among other ways in which it may impact a medical device manufacturer’s business, the PPACA:

Some of the provisions of the PPACA have yet to be implemented, and there have been judicial and Congressional challenges to certain aspects of the PPACA, as well as recent efforts by the Trump administration to repeal or replace certain aspects of the PPACA. President Trump has signed two Executive Orders and other directives designed to delay the implementation of certain provisions of the PPACA or otherwise circumvent some of the requirements for health insurance mandated by the PPACA. Concurrently, Congress has considered legislation that would repeal or repeal and replace all or part of the PPACA. While Congress has not passed comprehensive repeal legislation, two bills affecting the implementation of certain taxes under the PPACA have been signed into law. The Tax Cuts and Jobs Act of 2017, or the Tax Act, includes a provision repealing, 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”. The 2018 Appropriations Resolution delayed the implementation of certain PPACA-mandated fees, including, without limitation, the medical device excise tax. The Bipartisan Budget Act of 2018, or the BBA, among other things, amends the PPACA, effective January 1, 2019, to close the coverage gap in most Medicare drug plans, commonly referred to as the “donut hole”. In July 2018, CMS published a final rule permitting further collections and payments to and from certain PPACA qualified health plans and health insurance issuers under the PPACA risk adjustment program in response to the outcome of federal district court litigation regarding the method CMS uses to determine this risk adjustment. On December 14, 2018, a U.S. District Court Judge in the Northern District of Texas, or Texas District Court Judge, ruled that the individual mandate is a critical and inseverable feature of the PPACA, and therefore, because it was repealed as part of the Tax Act, the remaining provisions of the PPACA are invalid as well. While the Texas District Court Judge, as well as the Trump administration and CMS, have stated that the ruling will have no immediate effect, it is unclear how this decision, subsequent appeals, if any, and other efforts to repeal and replace the PPACA will impact the PPACA.

35

In addition, other legislative changes have been proposed and adopted since the PPACA was enacted. On August 2, 2011, President Obama signed into law the Budget Control Act of 2011, which, among other things, created the Joint Select Committee on Deficit Reduction to recommend to Congress proposals in spending reductions. The Joint Select Committee did not achieve a targeted deficit reduction of at least $1.2 trillion for the years 2013 through 2021, triggering the legislation’s automatic reduction to several government programs. This 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, including the Bipartisan Budget Act of 2018, will stay in effect through 2027 unless additional Congressional action is taken. On January 2, 2013, President Obama signed into law the American Taxpayer Relief Act of 2012, or the ATRA, which, among other things, further reduced Medicare payments to several types of providers and increased the statute of limitations period for the government to recover overpayments to providers from three to five years. In addition, the Medicare Access and CHIP Reauthorization Act of 2015, enacted on April 16, 2015, or MACRA, repealed the formula by which Medicare made annual payment adjustments to physicians and replaced the former formula with fixed annual updates and a new system of incentive payments scheduled to begin in 2019 that are based on various performance measures and physicians’ participation in alternative payment models such as accountable care organizations.

Recently there has been heightened governmental scrutiny over the manner in which manufacturers set prices for their marketed products, which has resulted in several U.S. Congressional inquiries and proposed federal legislation designed to, among other things, bring more transparency to product pricing, reduce the cost of certain products under Medicare, review the relationship between pricing and manufacturer patient programs, and reform government program reimbursement methodologies. At the state level, individual states in the United States are also increasingly passing legislation and implementing regulations designed to control product pricing, including price or patient reimbursement constraints, discounts, restrictions on certain product access and marketing cost disclosure and transparency measures.

It is likely that additional state and federal healthcare reform measures will be adopted in the future, any of which could limit the amounts that federal and state governments will pay for healthcare products and services, which could result in reduced demand for a medical device manufacturer’s products or additional pricing pressure.

Japanese Regulation

In Japan, medical devices must be approved prior to importation and commercial sale by the MHLW. The approval process identifies a Marketing Authorization Holder, or MAH, who is designated as the only authorized seller of products. Manufacturers of medical devices outside of Japan who do not operate through a Japanese entity are able to designate a MAH who will apply for product approval and take responsibility for the medical device as designated. The MHLW evaluates each device for safety and efficacy. As part of its approval process, the MHLW may require that the product be tested in Japanese laboratories. The approval process ranges in length and certain medical devices may require a longer review period for approval. Once a device is approved, the MHLW issues a Shonin to the MAH or designated MAH, thereby permitting such entity to import the device into Japan for sale.

After a device is approved for importation and commercial sale in Japan, the MHLW continues to monitor sales of approved products for compliance with labeling regulations, which prohibit promotion of devices for unapproved uses, and reporting regulations, which require reporting of product malfunctions, including serious injury or death caused by any approved device. Failure to comply with applicable regulatory requirements can result in enforcement action by the MHLW, which may include fines, injunctions, and civil penalties; recall or seizure of our products; operating restrictions; partial suspension or total shutdown of sales in Japan; or criminal prosecution.

Employees

As of December 31, 2018, we had 191 employees, with 133 employees on our sales and customer support team, 33 in research and development, including clinical, regulatory and certain quality functions, 3 employees in operations and 22 employees in general and administrative. We have never had a work stoppage and none of our employees are covered by collective bargaining agreements or represented by a labor union. We believe our employee relations are good.

You should carefully consider the risks and uncertainties described below and the other information contained in this Annual Report on Form 10-K before deciding whether to invest in our common stock. The occurrence of any of the events or developments described below could harm our business, financial condition, results of operations and prospects. As a result, the market price of our common stock could decline, and you may lose all or part of your investment.

Risks Related to Our Business and Industry

We have incurred losses in the past and may be unable to achieve or sustain profitability in the future.

We have incurred net losses since inception, including net losses of $24.1 million and $16.1 million for the years ended December 31, 2018 and 2017 respectively. As a result of ongoing losses, as of December 31, 2018, we had an accumulated deficit of $221.0 million. We expect to continue to incur significant sales and marketing, product development, regulatory and other expenses as we continue to expand our marketing efforts to increase adoption of our products and expand existing relationships with our customers, to obtain regulatory clearances or approvals for our products in additional countries and for additional indications, and to develop new products or add new features to our existing products. The net losses we incur may fluctuate significantly from quarter to quarter. We will need to generate significant additional revenues to achieve and sustain profitability, and even if we achieve profitability, we cannot be sure that we will remain profitable for any substantial period of time. Our failure to achieve or maintain profitability could negatively impact the value of our common stock.

We rely on the sale of our NeuroStar Advanced Therapy System and treatment sessions to generate revenues.

At present, we rely on the sale of our NeuroStar Advanced Therapy System and treatment sessions to generate revenues, and we expect to generate substantially all of our revenues in the foreseeable future from sales of these and any related products. Because the market for TMS therapy is still developing and contains a limited number of market participants, sales of our products could be negatively impacted by unfavorable market reactions to our or other TMS devices. If the use of our or other TMS therapies results in serious adverse events, or such products malfunction or are misused, patients and psychiatrists may attribute such negative events to TMS therapy generally, which may adversely affect market adoption of our products. Additionally, if patients undergoing treatment with a NeuroStar Advanced Therapy System perceive the benefits to be inadequate or adverse events too numerous or severe compared to the relevant rates of alternative TMS therapies or pharmaceutical options, it will be difficult to demonstrate the value of our NeuroStar Advanced Therapy System to patients and psychiatrists. As a result, demand for and the use of our NeuroStar Advanced Therapy System may decline or may not increase at the pace or to the levels we expect.

If coverage is unavailable or reimbursement from third-party payors for treatments using our products significantly declines, psychiatrists may be reluctant to use our products.

In the United States, sales of our products will depend, in part, on the extent to which the treatment sessions using our products are covered and reimbursed by third-party payors, including private insurers and government healthcare programs. Even if a third-party payor covers a particular treatment that uses our products, the resulting reimbursement rate may not be adequate to cover a provider’s cost to purchase our products or ensure such purchase is profitable for the provider. Further, patients who are treated in-office for a medical condition generally rely on third-party payors to reimburse all or part of the costs associated with the treatment and may be unwilling to undergo such treatment in the absence of coverage and adequate reimbursement, or due to large annual deductibles associated with certain health insurance plans.

Reimbursement by a third-party payor may depend upon a number of factors, including the third-party payor’s determination that a treatment is neither experimental nor investigational, safe, effective, and medically necessary, appropriate for the specific patient, cost-effective, supported by peer-reviewed medical journals and included in clinical practice guidelines.

38

In the United States, there is no uniform policy of coverage and reimbursement among third-party payors. Third-party payors often rely upon Medicare coverage policies and payment limitations in setting their own reimbursement policies, but also have their own methods and approval process apart from Medicare coverage and reimbursement determinations. Therefore, coverage and reimbursement for treatments can differ significantly from payor to payor. Decisions regarding the extent of coverage and amount of reimbursement to be provided for an in-office treatment is made on a plan-by-plan basis. One payor’s determination to provide coverage for a specific treatment does not assure that other payors will also provide coverage, and adequate reimbursement.

In addition, the federal government and state legislatures have continued to implement cost containment programs, including price controls and restrictions on coverage and reimbursement. To contain costs, governmental healthcare programs and third-party payors are increasingly challenging the price, scrutinizing the medical necessity and reviewing the cost-effectiveness of medical treatments.

Outside of the United States, reimbursement systems vary significantly by country. Many foreign markets, including Japan, have government-managed healthcare systems that govern reimbursement for psychiatric treatments and procedures. Additionally, some foreign reimbursement systems provide for limited payments in a given period and therefore result in extended payment periods. If adequate levels of reimbursement from third-party payors outside of the United States are not obtained, international sales of our products may not materialize or grow significantly.

The marketability of our products may suffer if the government and third-party payors fail to provide adequate coverage and reimbursement. Even if favorable coverage and reimbursement status is attained, less favorable coverage policies and reimbursement rates may be implemented in the future.

If we are unable to adequately train psychiatrists and other treatment providers on the safe and appropriate use of our products, we may be unable to achieve our expected growth.

There is a learning process involved for treatment providers to become proficient in the use of our products, which requires us to spend considerable time and resources for training. It is critical to the success of our commercialization efforts to train a sufficient number of psychiatrists and to provide them with adequate, ongoing instruction and training in the use of our products. This training process generally requires psychiatrists to review and study product materials, engage in multi-day, hands-on training sessions for up to four hours a day and participate in a multi-day observational period prior to treating patients independently. This training process may also take longer than expected or be more complicated than the psychiatrists or their personnel are comfortable with and may therefore affect our ability to increase sales. Convincing psychiatrists to dedicate the time and energy necessary for adequate training is challenging, and we may not be successful in these efforts.

Psychiatrists and patients may be slow to adopt and use TMS therapies.

TMS therapy is an emerging treatment option for patients suffering from MDD. As a result, psychiatrist and patient awareness of TMS therapy as a treatment option for MDD, and experience with TMS therapies, is limited. Our success depends in large part on our ability to educate and train psychiatrist and patients, and successfully demonstrate the safety, tolerability, ease of use, efficacy, cost effectiveness and other merits of our NeuroStar Advanced Therapy System. We have been engaging in an active marketing campaign to raise awareness of our NeuroStar Advanced Therapy System and its benefits among psychiatrists, but we cannot assure you that these efforts will be successful or that they will not prove to be cost-prohibitive. Some psychiatrists may also find the initial patient set up and the subsequent procedures for future treatment sessions to be difficult or complicated, or could be wary of the initial investment required for the purchase of the NeuroStar Advanced Therapy System, which may impact their decision to purchase or use the NeuroStar Advanced Therapy System as part of their practice. Similarly, psychiatrists may find it difficult to hire additional staff, allocate sufficient space or operationalize our NeuroStar Advanced Therapy System, which could slow its adoption.

In addition, psychiatrists may not derive sufficient cash flow from using the NeuroStar Advanced Therapy Systems due to their own practice economics or otherwise. Failure to achieve economic benefits from the purchase or use of the NeuroStar Advanced Therapy System would adversely affect our customers’ purchase of treatment sessions. These factors could also reduce the number of procedures performed using our NeuroStar Advanced Therapy System, and if we do not facilitate the utilization of our products by our customers, our revenues and results of operations could be harmed.

39

Our success depends in part upon patient satisfaction with the effectiveness of our NeuroStar Advanced Therapy System.

In order to generate repeat and referral business, patients must be satisfied with the effectiveness of our NeuroStar Advanced Therapy System. Clinical studies demonstrate that, in order to be effective, our products must be used for a period of four to six weeks, and require a patient to return to a psychiatrist’s office five days a week during that period in order to receive the recommended course of treatment. Since patients who achieve response or remission using our therapy will obtain these results gradually over this treatment period, their perception of their results may vary depending on their compliance with the prescribed treatment course.

We train our psychiatrist customers to select the appropriate patient candidates for treatment using the NeuroStar Advanced Therapy System, explain to their patients the time-period over which the results from a treatment course can be expected to occur, and measure the success of treatments using medical guidelines. However, our psychiatrist customers may not select appropriate patient candidates for NeuroStar Advanced Therapy treatment, which may produce results that may not meet patients’ expectations. In addition, the efficacy of treatment is dependent on proper patient set up at the initial treatment session and duplication of that set up at future treatment sessions. To the extent psychiatrists do not make the proper measurements for a specific patient or use the same procedures at each treatment session, it could result in variability of the treatment efficacy and results for the patient. If patients are not satisfied with the results of our NeuroStar Advanced Therapy System, our reputation and future sales will suffer.

We operate in a very competitive environment and if we are unable to compete successfully against our existing or potential competitors, our sales and operating results may be negatively affected.

Our currently marketed products are, and any future products we develop and commercialize will be, subject to intense competition. The industry in which we operate is subject to rapid change and is highly sensitive to the introduction of new products or other market activities of current or new industry participants. Our ability to compete successfully will depend on our ability to develop products that reach the market in a timely manner, to receive adequate coverage and reimbursement from third-party payors, and to successfully demonstrate to psychiatrists and patients the merits of our products compared to those of our competitors. If we are not successful in convincing others of the merits of our products, including in comparison to those of our competitors, or educating them on the use of our products, they may not use our products or use them effectively and we may be unable to increase our sales.

We have competitors that sell other forms of TMS therapy, including Brainsway, Magstim, MagVenture, CloudTMS and Nexstim, that compete directly with the NeuroStar Advanced Therapy System. Competing TMS therapy companies have developed and may develop additional treatments that can be administered for shorter time periods or for indications outside of MDD, or may develop treatments that have improved efficacy when compared to our products or that require a less significant investment of resources from psychiatrists. We also face competition from pharmaceutical and other companies that develop competitive products, such as antidepressant medications. Our commercial opportunity could be reduced or eliminated if these competitors develop and commercialize antidepressant medications or other treatments that are safer, more convenient or more effective than the NeuroStar Advanced Therapy System. At any time, these and other potential market entrants may develop treatment alternatives that may render our products uncompetitive.

In addition, our competitors may have more established distribution networks than we do, or may be acquired by enterprises that have more established distribution networks than we do. Our competitors may also develop and patent processes or products earlier than we can or obtain domestic or international regulatory clearances or approvals for competing products more rapidly than we can, which could impair our ability to develop and commercialize similar products. We also compete with our competitors in acquiring technologies and technology licenses complementary to our products or advantageous to our business. In addition, we compete with our competitors to engage the services of independent distributors outside the United States, both those presently working with us and those with whom we hope to work as we expand.

40

We may face difficulties encountered by companies in new and evolving markets.

In assessing our prospects, you must consider the risks and difficulties frequently encountered by companies in new and evolving markets. These risks include our ability to:

If we are unable to successfully expand our sales and customer support team and adequately address our customers’ needs, it could negatively impact sales and market acceptance of our products and we may never generate sufficient revenues to achieve or sustain profitability.

Our operating results are directly dependent upon the sales and marketing efforts of our sales and customer support team in the United States and our independent third-party distributors outside of the United States. If our employees or our independent distributors fail to adequately promote, market and sell our products, our sales could significantly decrease.

In addition, our future sales will largely depend on our ability to increase our marketing efforts and adequately address our customers’ needs. We believe it is necessary to expand our sales force, including by hiring additional sales representatives or distributors with specific technical backgrounds that can support our customers’ needs.

As we launch new products, expand our product offerings to new indications and increase our marketing efforts with respect to existing products, we will need to expand the reach of our marketing and sales networks. Our future success will depend largely on our ability to continue to hire, train, retain and motivate skilled employees, and distributors with significant technical knowledge in various areas. New hires require training and take time to achieve full productivity. If we fail to train new hires adequately, or if we experience high turnover in our sales force in the future, new hires may not become as productive as may be necessary to maintain or increase our sales. If we are unable to expand our sales and marketing capabilities domestically and internationally, we may be unable to effectively commercialize our products.

The loss of our senior management or our inability to attract and retain highly skilled executives, salespeople and product development personnel could negatively impact our business.

Our success depends on the skills, experience and performance of the members of our executive management team. The individual and collective efforts of these employees will be important as we continue to develop our products and as we expand our commercial activities. We believe that it is challenging to identify individuals with the requisite skills to serve in many of our key positions, and the loss or incapacity of existing members of our executive management team could negatively impact our operations. We do not maintain key man life insurance on any of our employees. The existence of our Chief Executive Officer’s employment agreement does not guarantee our retention of our Chief Executive Officer for any period of time.

41

Our commercial, supply chain and research and development programs and operations depend on our ability to attract and retain highly skilled managers, salespeople and product development and customer training personnel. We may be unable to attract or retain qualified managers, salespeople or product development and customer training personnel in the future due to the competition for qualified personnel in the medical treatment and device fields. We also face competition from universities and public and private research institutions in recruiting and retaining highly qualified scientific personnel. Recruiting and retention difficulties can limit our ability to support our commercial, supply chain and research and development programs. The loss of key employees, the failure of any key employee to perform or our inability to attract and retain skilled employees, as needed, or an inability to effectively plan for and implement a succession plan for key employees could harm our business.

Our long-term growth depends on our ability to commercialize our approved products for current and future indications and to develop and commercialize additional products through our research and development efforts. If we fail to do so we may be unable to compete effectively.

In order to increase our future revenues, we must successfully enhance our existing product offerings and introduce new products in response to changing customer demands and competitive pressures and technologies. Our industry is characterized by intense competition, including from lower-cost competitors, rapid technological changes, new product introductions and enhancements and evolving industry standards. We also face competition from large pharmaceutical companies with greater capital. Our business prospects depend in part on our ability to develop and commercialize new products and applications for our technology, including in new markets that develop as a result of technological, pharmaceutical and scientific advances, while improving the performance and cost-effectiveness of our products. New pharmaceutical products, technologies, techniques or other products could emerge that might offer better combinations of price and performance than our products. It is important that we anticipate changes in technology and market demand, as well as psychiatrist practices to successfully develop, obtain clearance or approval, if required, and successfully introduce new, enhanced and competitive technologies to meet our prospective customers’ needs on a timely and cost-effective basis.

We might be unable to successfully further commercialize or develop or obtain regulatory clearances or approvals to market new products or our existing products for additional indications. For example, our NeuroStar Advanced Therapy System did not meet the primary endpoint in the initial phase of the clinical trial of adolescents with MDD. While we intend to complete the remaining phases of this clinical trial, in light of these results we are unlikely to seek clearance for this indication. Additionally, these products and any future products, even if cleared, might not be accepted by psychiatrists or the third-party payors who reimburse for the procedures performed with our products. The success of any new product offering or enhancement to an existing product will depend on numerous additional factors, including our ability to:

If we do not develop and obtain regulatory clearances or approvals for new products or indications or product enhancements in time to meet market demand, or if there is insufficient demand for these products or enhancements, our results of operations will suffer. Our research and development efforts may require a substantial investment of time and resources before we are adequately able to determine the commercial viability of a new product, technology, material or other innovation. In addition, even if we are able to develop enhancements or new generations of our products successfully, these enhancements or new generations of products may not produce sales in excess of the costs of development and they may be quickly rendered obsolete by changing customer preferences or the introduction by our competitors of products embodying new technologies or features.

42

Nevertheless, we must carefully manage our introduction of new products. If potential customers believe such products will offer enhanced features or be sold for a more attractive price, they may delay purchases until such products are available. We may also have excess or obsolete inventory as we transition to new products, and we have limited experience in managing product transitions.

We rely on single-source suppliers for some components used in our NeuroStar Advanced Therapy System and on a single manufacturer for the assembly of our NeuroStar Advanced Therapy System, and we may be unable to find replacements or immediately transition to alternative parties for these components.

We rely on single-source suppliers for some components used in our NeuroStar Advanced Therapy System, and we do not have long-term supply contracts with these suppliers. Furthermore, we rely on a single manufacturer for the assembly of the mobile console and patient positioning system used in our NeuroStar Advanced Therapy System. For us to be successful, our suppliers and contract manufacturer must be able to provide us with components in substantial quantities, in compliance with regulatory requirements, in accordance with agreed upon specifications, at acceptable costs and on a timely basis. While these suppliers have generally met our demand requirements on a timely basis in the past, their ability and willingness to continue to do so going forward may be limited for several reasons, including our lack of long-term agreements with those suppliers, our relative importance as a customer of those suppliers, or, as applicable, their ability to produce the components for or provide assembly services to manufacture our NeuroStar Advanced Therapy System. An interruption in our commercial operations could occur if we encounter delays or difficulties in securing these components or manufactured products, if we cannot obtain an acceptable substitute.

Any transition to a new supplier or contract manufacturer could be time-consuming and expensive, may result in interruptions in our operations and product delivery, could affect the performance specifications of our NeuroStar Advanced Therapy System or could require that we modify its design. If we are required to change our contract manufacturer, we will be required to verify that the new manufacturer maintains facilities, procedures and operations that comply with our quality and applicable regulatory requirements, which could further impede our ability to manufacture our products in a timely manner. If the change in manufacturer results in a significant change to any product, a new 510(k) clearance from the FDA or similar non-U.S. regulatory authorization may be necessary before we implement the change, which could cause a substantial delay. We cannot assure you that we will be able to identify and engage alternative suppliers or contract manufacturers on similar terms or without delay. Furthermore, our contract manufacturer could require us to move to a different production facility. The occurrence of any of these events could harm our ability to meet the demand for our NeuroStar Advanced Therapy System in a timely and cost-effective manner.

We may be unable to manage our anticipated growth effectively, which could make it difficult to execute our business strategy.

We have been growing rapidly and have a relatively short history of operating as a commercial company. For example, our revenues grew from $40.4 million for the year ended December 31, 2017 to $52.8 million for the year ended December 31, 2018. We intend to continue to grow our business operations and may experience periods of rapid growth and expansion. This anticipated growth could create a strain on our organizational, administrative and operational infrastructure, including our supply chain operations, quality control, technical support and customer service, sales force management and general and financial administration. We may be unable to maintain the quality, or delivery timelines, of our products or customer service or satisfy customer demand if our business grows too rapidly. Our ability to manage our growth properly will require us to continue to improve our operational, financial and management controls, and our reporting systems and procedures. We may implement new enterprise software systems in a number of areas affecting a broad range of business processes and functional areas. The time and resources required to implement these new systems is uncertain and failure to complete this in a timely and efficient manner could harm our business.

As our commercial operations and sales volume grow, we will need to continue to increase our workflow capacity for our supply chain, customer service, training and education personnel, billing, accounting reporting and general process improvements and expand our internal quality assurance program, among other things. Because our products require us to devote significant resources to training our customers on the use, and educating our customers on the benefits, of our products, we will be required to expand these personnel as we increase our sales efforts. We may not successfully implement these increases in scale or the expansion of our personnel, which could harm our business.

43

We rely and, in the future, expect to rely on a network of third-party distributors to market and distribute our products internationally, and if we are unable to maintain and expand this network, we may be unable to generate anticipated sales.

We rely, and expect to rely in the future, on a network of third-party distributors to market and distribute our products in international markets. We currently sell our products in five countries outside of the United States and plan to market and sell our products through our exclusive distribution agreement in Japan once we attain reimbursement approval. We are assessing the opportunity to continue expanding into other international markets. We may face significant challenges and risks in managing a geographically dispersed distribution network. We have limited ability to control any third-party distributors. Our distributors may be unable to successfully market and sell our products and may not devote sufficient time and resources to support the marketing, sales, education and training efforts that we believe enable the products to develop, achieve or sustain market acceptance. Additionally, in some international jurisdictions, we rely on our distributors to manage the regulatory process, while complying with all applicable rules and regulations, and we are dependent on their ability to do so effectively. In addition, if a dispute arises with a distributor or if a distributor is terminated by us or goes out of business, it may take time to locate an alternative distributor, to seek appropriate regulatory approvals and to train new personnel to market our products, and our ability to sell those systems in the region formerly serviced by such terminated distributor could be harmed. Any of these factors could reduce our revenues from affected markets, increase our costs in those markets or damage our reputation. In addition, if an independent distributor were to depart and be retained by one of our competitors, we may be unable to prevent that distributor from helping competitors solicit business from our existing customers, which could further adversely affect our sales. As a result of our reliance on third-party distributors, we may be subject to disruptions and increased costs due to factors beyond our control, including labor strikes, third-party error and other issues. If the services of any of these third-party distributors become unsatisfactory, we may experience delays in meeting our customers’ demands and we may be unable to find a suitable replacement on a timely basis or on commercially reasonable terms. Any failure to deliver products in a timely manner may damage our reputation and could cause us to lose potential customers.

We face risks associated with our international business.

We currently market and sell our products outside of the United States, including in Japan, and plan to market and sell our products through our exclusive distribution agreement in Japan. Once we attain satisfactory reimbursement approval, we expect that sales of our NeuroStar Advanced Therapy System in Japan will increase.

The sale and shipment of our products across international borders, as well as the purchase of components and products from international sources, subjects us to extensive U.S. and other foreign governmental trade, import and export and customs regulations and laws. Compliance with these regulations and laws is costly and exposes us to penalties for non-compliance. We expect our international activities will be dynamic over the foreseeable future as we continue to pursue opportunities in international markets. Our international business operations are subject to a variety of risks, including:

44

We are assessing the opportunity to expand into other international markets. However, our expansion plans may not be realized, or if realized, may not be successful. We expect each market to have particular regulatory hurdles to overcome, and future developments in these markets, including the uncertainty relating to governmental policies and regulations, could harm our business.

Our employees, consultants, distributors and other commercial partners 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, consultants, distributors and other commercial partners may engage in inappropriate, fraudulent or illegal activity. Misconduct by these parties could include intentional, reckless or negligent conduct or other unauthorized activities that violate the regulations of the FDA and other U.S. healthcare regulators, as well as non-U.S. regulators, including by violating laws requiring the reporting of true, complete and accurate information to such regulators, manufacturing standards, healthcare fraud and abuse laws and regulations in the United States and abroad or 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, including the sale of medical devices, are subject to extensive laws and regulations intended to prevent fraud, misconduct, 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. It is not always possible to identify and deter misconduct by our employees, distributors and other third parties, 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 comply with these laws or regulations. These risks may be more pronounced, and we may find that the processes and policies we have implemented are not effective at preventing misconduct. If any actions are instituted against us and we are not successful in defending ourselves or asserting our rights, those actions could result in the imposition of significant fines or other sanctions, including the imposition of civil, criminal and administrative penalties, damages, monetary fines, individual imprisonment, disgorgement, possible exclusion from participation in government healthcare programs, additional reporting obligations and oversight if we become subject to a corporate integrity agreement or other agreement to resolve allegations of non-compliance with these laws, contractual damages, reputational harm, diminished profits and future earnings and the curtailment of our operations. Whether or not we are successful in defending against such actions or investigations, we could incur substantial costs, including legal fees, and divert the attention of management in defending ourselves against any of these claims or investigations.

We rely in part on third parties to conduct our clinical trials. If these third parties fail to perform their duties on time or as expected, we may not be able to obtain regulatory approval for additional indications that we may seek for the NeuroStar Advanced Therapy System.

Our clinical trials are managed by our own staff and personnel, but we rely in part upon certain third-parties, including clinical trial sites, medical institutions, clinical research organizations, or CROs, and private practices, for, among other things, site monitoring, statistical work and electronic data capture in our clinical trials. Nevertheless, we are responsible for ensuring that each of our clinical trials is conducted in accordance with applicable protocols, and legal, regulatory and scientific standards, including current good clinical practices, or cGCPs, which are

45

regulations and guidelines enforced by the FDA and comparable foreign regulatory authorities for clinical trials. If we or any such third parties fail to comply with applicable cGCPs, the clinical data generated in such trials may be deemed unreliable and the FDA or comparable foreign regulatory authorities may require us to perform additional clinical trials before approving a marketing application for any particular indication. In addition, if such third parties do not devote sufficient time and resources to our clinical trials or otherwise carry out their contractual duties or obligations or meet expected deadlines, if they need to be replaced or if the quality or accuracy of the clinical data they assist in obtaining is compromised due to the failure to adhere to our clinical protocols, regulatory requirements or for other reasons, our clinical trials may be extended, delayed or terminated, and we may not be able to obtain regulatory approval for or successfully commercialize our product candidates in a specified indication.

If product liability lawsuits are brought against us, our business may be harmed, and we may be required to pay damages that exceed our insurance coverage.

Our business exposes us to potential product liability claims that are inherent in the testing, manufacture and sale of medical devices for the treatment of MDD. Our treatments are designed for patients who suffer from significant psychiatric disorders, and these patients are more likely to experience significant adverse health outcomes, which could increase the risk of product liability lawsuits. Furthermore, if psychiatrists are not sufficiently trained in the use of our products, they may misuse or ineffectively use our products, which may result in unsatisfactory patient outcomes. We could become the subject of product liability lawsuits alleging that component failures, malfunctions, manufacturing flaws, design defects or inadequate disclosure of product-related risks or product-related information resulted in an unsafe condition or injury to patients.

Regardless of the merit or eventual outcome, product liability claims may result in:

Our existing product liability insurance coverage may be inadequate to protect us from any liabilities we might incur. If a product liability claim or series of claims is brought against us for uninsured liabilities or in excess of our insurance coverage, our business could suffer. Any product liability claim brought against us, with or without merit, could result in the increase of our product liability insurance rates or the inability to secure coverage in the future. In addition, a recall of some of our products, whether or not the result of a product liability claim, could result in significant costs and loss of customers.

Our insurance policies protect us only from some business risks, which will leave us exposed to significant uninsured liabilities.

We do not carry insurance for all categories of risk that our business may encounter. Some of the policies we currently maintain include general liability, cybersecurity liability, employee benefits liability, property, umbrella, workers’ compensation, products and clinical trial liability and directors’ and officers’ insurance. We do not know, however, if these policies will provide us with adequate levels of coverage. Any significant uninsured liability may require us to pay substantial amounts, which would adversely affect our cash position and results of operations.

46

We bear the risk of warranty claims on our products.

We bear the risk of warranty claims on the products we supply for two years from the date of delivery. There can be no assurance that we will not face increased claims in the future. We may not be successful in claiming recovery under any warranty or indemnity provided to us by our suppliers or vendors in the event of a successful warranty claim against us by a customer or that any recovery from such vendor or supplier would be adequate. In addition, warranty claims brought by our customers related to third-party components may arise after our ability to bring corresponding warranty claims against such suppliers expires, which could result in costs to us.

We could be negatively impacted by violations of applicable anti-corruption laws or violations of our internal policies designed to ensure ethical business practices.

We operate in a number of countries throughout the world, including in countries that do not have as strong a commitment to anti-corruption and ethical behavior that is required by U.S. laws or by our corporate policies. We are subject to the risk that we, our U.S. employees or any future employees or consultants located in other jurisdictions or any third parties such as our distributors that we engage to do work on our behalf in foreign countries may take action determined to be in violation of anti-corruption laws in any jurisdiction in which we conduct business, including the FCPA. The FCPA generally prohibits covered entities and their intermediaries from engaging in bribery or making other prohibited payments, offers or promises to foreign officials for the purpose of obtaining or retaining business or other advantages. In addition, the FCPA imposes recordkeeping and internal controls requirements on publicly traded corporations and their foreign affiliates, which are intended to, among other things, prevent the diversion of corporate funds to the payment of bribes and other improper payments, and to prevent the establishment of “off books” slush funds from which such improper payments can be made.

We will face significant risks if we fail to comply with the FCPA and other laws that prohibit improper payments, offers or promises of payment to foreign governments and their officials and political parties by us and other business entities for the purpose of obtaining or retaining business or other advantages. In many foreign countries, particularly in countries with developing economies, it may be a local custom that businesses operating in such countries engage in business practices that are prohibited by the FCPA or other laws and regulations. We have implemented company policies relating to compliance with the FCPA and similar laws. However, such policies may not be effective at preventing all potential FCPA or other violations. Although our agreements with our international distributors state our expectations for our distributors’ compliance with U.S. laws, including the FCPA, and provide us with various remedies upon any non-compliance, including the ability to terminate the agreement, our distributors may not comply with U.S. laws, including the FCPA.

Any violation of the FCPA or any similar anti-corruption law or regulation could result in substantial fines, sanctions, civil and/or criminal penalties and curtailment of operations in certain jurisdictions and might harm our business, financial condition or results of operations.

If we experience significant disruptions in our information technology systems, our business may be adversely affected.

We depend on our information technology systems for the efficient functioning of our business, including for our TrakStar system and accounting, data storage, compliance, purchasing and inventory management. We do not have redundant systems at this time. While we will attempt to mitigate interruptions, we may experience difficulties in implementing upgrades to our information technology systems, which would impact our business operations, or experience difficulties in operating our business during the upgrade, either of which could disrupt our operations, including our ability to provide customers with data on patient outcomes, track the usage of our products, timely ship and track product orders, project inventory requirements, manage our supply chain and otherwise adequately service our customers or disrupt our customers’ ability to access patient data or use our products for treatments. In the event we experience significant disruptions as a result of the current implementation of our information technology systems, we may be unable to repair our systems in an efficient and timely manner. Accordingly, such events may disrupt or reduce the efficiency of our entire operation and have a material adverse effect on our results of operations and cash flows. Currently we carry business interruption coverage to mitigate any potential losses, but we cannot be certain that such potential losses will not exceed our policy limits.

47

We are increasingly dependent on sophisticated information technology for our infrastructure. Our information systems require an ongoing commitment of significant resources to maintain, protect and enhance existing systems. Failure to maintain or protect our information systems and data integrity effectively could have a materially adverse effect on our business.

Performance issues, service interruptions or price increases by our shipping carriers could adversely affect our business and harm our reputation and ability to provide our services on a timely basis.

Expedited, reliable shipping is essential to our operations. We rely heavily on providers of transport services for reliable and secure point-to-point transport of our products to our customers and for tracking of these shipments. Should a carrier encounter delivery performance issues such as loss, damage or destruction of any systems, it would be costly to replace such systems in a timely manner and such occurrences may damage our reputation and lead to decreased demand for our products and increased cost and expense to our business. In addition, any significant increase in shipping rates could adversely affect our operating margins and results of operations. Similarly, strikes, severe weather, natural disasters or other service interruptions affecting delivery services we use would adversely affect our ability to process orders for our products on a timely basis.

Security and privacy breaches may expose us to liability and harm our reputation and business.

As part of our business we receive and process information about our customers, partners and their patients, including protected health information, or PHI, and we may store or contract with third parties to store our customers’ data, including PHI. PHI, a subset of individually identifiable information, is regulated at the federal level by the Health Insurance Portability and Accountability Act, or HIPAA, as amended by the Health Information and Technology for Economic and Clinical Health Act of 2009, or HITECH, and by various laws at the state level, as more fully described below. We are required to safeguard PHI in accordance with HIPAA and, as a business associate, we are also directly liable for compliance with HIPAA.

While we implemented security measures relating to our NeuroStar Advanced Therapy System and TrakStar database, specifically, and our operations, generally, those measures may not prevent security breaches that could harm our business. Advances in computer capabilities, inadequate technology or facility security measures or other factors may result in a compromise or breach of our systems and the data and PHI we store and process. Our security measures may be breached as a result of actions by third parties or employee error or malfeasance. A party who is able to circumvent our security measures or exploit inadequacies in our security measures, could, among other things, misappropriate proprietary information, including information about our customers and their patients, cause the loss or disclosure of some or all of this information, cause interruptions in our or our customers’ operations or expose our customers to computer viruses or other disruptions or vulnerabilities. Any compromise of our systems or the data we store or process could implicate reporting requirements under HIPAA, result in a loss of confidence in the security of our software, damage our reputation, disrupt our business, lead to legal liability and adversely affect our results of operations. Moreover, a compromise of our systems could remain undetected for an extended period of time, exacerbating the impact of that compromise. Actual or perceived vulnerabilities may lead to claims against us by our customers, their patients or other third parties, including the federal and state governments. While our customer agreements typically contain provisions that seek to limit our liability, there is no assurance these provisions will be enforceable and effective under applicable law. In addition, the cost and operational consequences of implementing further data protection measures could be significant.

Employment litigation and unfavorable publicity could negatively affect our future business.

Employees may, from time to time, bring lawsuits against us regarding injury, creating a hostile work place, discrimination, wage and hour, sexual harassment and other employment issues. In recent years there has been an increase in the number of discrimination and harassment claims generally. Coupled with the expansion of social media platforms and similar devices that allow individuals access to a broad audience, these claims have had a significant negative impact on some businesses. Companies that have faced employment or harassment related lawsuits have had to terminate management or other key personnel and have suffered reputational harm that has negatively impacted their sales. If we were to face any employment related claims, our business could be negatively affected.

The 2017 comprehensive tax reform law could adversely affect our business and financial condition.

On December 22, 2017, President Trump signed into law new legislation, (Pub. L. 115-97), commonly referred to as the Tax Cuts and Jobs Act of 2017, that significantly revises the Internal Revenue Code of 1986, as amended. The newly enacted federal income tax law, among other things, contains significant changes to corporate taxation, including the reduction of the corporate tax rate from a top marginal rate of 35% to a flat rate of 21%, limitation of the tax deduction for interest expense to 30% of adjusted earnings (except for certain small businesses), limitation of the deduction for net operating losses to 80% of current year taxable income and elimination of net operating loss carrybacks, one time taxation of offshore earnings at reduced rates regardless of whether they are repatriated, elimination of U.S. tax on foreign earnings (subject to certain important exceptions), immediate deductions for certain new investments instead of deductions for depreciation expense over time, and modifying or repealing many business deductions and credits. Notwithstanding the reduction in the corporate income tax rate, the overall impact of the new federal tax law is uncertain and our business and financial condition could be adversely affected. In addition, it is uncertain how various states will respond to the newly enacted federal tax law. The impact of this tax reform on holders of our common stock is also uncertain and could be adverse. We urge our stockholders to consult with their legal and tax advisors with respect to this legislation and the potential tax consequences of investing in or holding our common stock.

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 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.

Our operations are vulnerable to interruption or loss due to natural or other disasters, power loss, strikes and other events beyond our control.

A major earthquake, fire or other disaster, such as a major flood, seasonal storms, or terrorist attack affecting our facilities, or those of our third-party manufacturers or suppliers, could significantly disrupt our or their operations, and delay or prevent product shipment or installation during the time required to repair, rebuild or replace our third-party manufacturers or suppliers’ damaged manufacturing facilities. These delays could be lengthy and costly. If any of our manufacturers’, suppliers’ or customers’ facilities are negatively impacted by a disaster, shipments of our products could be delayed. Additionally, customers may delay purchases of our products until operations return to normal. Even if we are able to quickly respond to a disaster, the ongoing effects of the disaster could create some uncertainty in the operations of our business. In addition, our or their facilities may be subject to a shortage of available electrical power and other energy supplies. Any shortages may increase our costs for power and energy supplies or could result in blackouts, which could disrupt the operations of our affected facilities and harm our business. In addition, concerns about terrorism, the effects of a terrorist attack, political turmoil or an outbreak of epidemic diseases could have a negative effect on our operations.

49

We may seek to grow our business through acquisitions or investments in new or complementary businesses, products or technologies, through the licensing of products or technologies from third parties. The failure to manage acquisitions, investments, licenses or other strategic alliances, or the failure to integrate them with our existing business, could harm our business.

Our success depends in part on our ability to continually enhance and broaden our product offerings in response to changing customer demands, competitive pressures, technologies and market pressures. Accordingly, from time to time we may consider opportunities to acquire, make investments in or license other technologies, products and businesses that may enhance our capabilities, complement our current products or expand the breadth of our markets or customer base. Potential and completed acquisitions, strategic investments, licenses and other alliances involve numerous risks, including:

We do not know if we will be able to identify acquisitions or strategic relationships we deem suitable, whether we will be able to successfully complete any such transactions on favorable terms or at all or whether we will be able to successfully integrate any acquired business, product or technology into our business or retain any key personnel, suppliers or distributors.

Foreign acquisitions involve unique risks in addition to those mentioned above, including those related to integration of operations across different cultures, languages and legal and regulatory environments, currency risks and the particular economic, political and regulatory risks associated with specific countries.

To finance any acquisitions, investments or strategic alliances, we may choose to issue shares of our common stock or other equity-linked securities as consideration, which could dilute the ownership of our stockholders. Additional funds may not be available on terms that are favorable to us, or at all. If the price of our common stock is low or volatile, we may be unable to consummate any acquisitions, investments or strategic alliances using our stock as consideration.

Our reported financial results may be adversely affected by changes in accounting principles generally accepted in the United States.

Generally accepted accounting principles in the United States, or U.S. GAAP, are subject to interpretation by the Financial Accounting Standards Board, or FASB, the U.S. Securities and Exchange Commission, or SEC, and various bodies formed to promulgate and interpret appropriate accounting principles. A change in these principles or interpretations could have a significant effect on our reported financial results and could affect the reporting of transactions completed before the announcement of a change.

Refer to “Note 4. Recent Accounting Pronouncements” in our audited financial statements and related notes thereto included elsewhere in this Annual Report on Form 10-K.

Our sales volumes and our results of operations may fluctuate over the course of the year.

We have experienced and may continue to experience meaningful variability in our sales and gross profit among quarters. A number of factors over which we have limited control, such as seasonal variations in revenues, may contribute to fluctuations in our financial results. In the first quarter, our results can be impacted by severe weather and by the resetting of annual U.S. patient healthcare insurance plan deductibles, which may cause delays in patients seeking NeuroStar Advanced Therapy treatments. Historically, we have seen a sequential decline in third quarter revenues, which we believe is attributable to summer vacation plans of psychiatrists and patients. In addition, the fourth quarter has consistently been a strong revenue quarter on a sequential basis primarily due to U.S. psychiatrists’ historical timing for capital expenditures and patients’ needs to exhaust remaining balances in flexible spending accounts.

Additional factors that we expect may contribute to variability in our sales and gross profit over the course of the year include:

Risks Related to Intellectual Property

If we are not able to obtain and enforce patent protection for our technologies, products, or product candidates, development and commercialization of our products and product candidates may be adversely affected.

Our commercial success will depend in part on our success in obtaining and maintaining issued patents and other intellectual property rights in the United States and elsewhere and protecting our proprietary technology. If we do not adequately protect our intellectual property and proprietary technology, competitors may be able to use our technologies and erode or negate any competitive advantage we may have, which could harm our business and ability to achieve profitability.

We have applied, and we intend to continue applying, for patents covering aspects of our technologies that we deem appropriate. However, the patent process is expensive and time consuming, and we may not be able to apply for patents on certain aspects of our current or future products and other technologies in a timely fashion, at a reasonable cost, in all jurisdictions, or at all, and any potential patent coverage we obtain may not be sufficient to prevent substantial competition.

We cannot offer any assurances about which, if any, of our patent applications will issue or whether any of our issued patents will be found invalid and unenforceable or will be threatened by third parties. Any patent applications we file may be challenged and may not result in issued patents or may be invalidated or narrowed in scope after they are issued. We also cannot provide any assurances that any of our patents have, or that any of our pending patent applications that mature into issued patents will include, claims with a scope sufficient to protect and provide exclusivity for our products, any additional features we develop for our products or any new products. Other parties may have designed around our claims or developed technologies that may be related or competitive to our platform, may have filed or may file patent applications and may have received or may receive patents that overlap or conflict with our patent applications, either by claiming the same methods or devices or by claiming subject matter that could dominate our patent position. Any successful opposition to these patents or any other patents owned by or, if applicable in the future, licensed to us could deprive us of rights necessary for the practice of our technologies or the successful commercialization of any products or product candidates that we may develop. Since patent applications in the US and most other countries are confidential for a period of time after filing, we cannot be certain that we or our licensors were the first to file any patent application related to our technologies, products, or product candidates. Furthermore, an interference proceeding can be provoked by a third party or instituted by the United States Patent and Trademark Office, or the USPTO, to determine who was the first to invent any of the subject matter covered by the patent claims of our applications for any application with an effective filing date before March 16, 2013.

51

The patent positions of medical device companies, including our patent position, may involve complex legal and factual questions, and, therefore, the scope, validity and enforceability of any patent claims that we may obtain cannot be predicted with certainty. Patents, if issued, may be challenged, deemed unenforceable, invalidated or circumvented. Once granted, patents may remain open to opposition, interference, re-examination, post-grant review, inter partes review, nullification or derivation action in court or before patent offices or similar proceedings for a given period after allowance or grant, during which time third parties can raise objections against such initial grant. Proceedings challenging our patents, which may continue for a protracted period of time, could result in either loss of the patent or denial of the patent application or loss or reduction in the scope of one or more of the claims of the patent or patent application. In addition, such proceedings may be costly. Thus, any patents that we may own may not provide any protection against competitors. Furthermore, an adverse decision in an interference proceeding can result in a third party receiving the patent right sought by us, which in turn could affect our ability to commercialize our products.

Furthermore, though an issued patent is presumed valid and enforceable, its issuance is not conclusive as to its validity or its enforceability and it may not provide us with adequate proprietary protection or competitive advantages against competitors with similar products. Competitors may also be able to design around our patents. Other parties may develop and obtain patent protection for alternative and possibly more effective technologies, designs or methods. We may be unable to prevent the unauthorized disclosure or use of our technical knowledge or trade secrets by consultants, suppliers, vendors, former employees and current employees. The laws of some foreign countries do not protect our proprietary rights to the same extent as the laws of the United States, and we may encounter significant problems in protecting our proprietary rights in these countries.

Our ability to enforce our patent rights depends on our ability to detect infringement. It may be difficult to detect infringers who do not advertise the components that are used in their products. Moreover, it may be difficult or impossible to obtain evidence of infringement in a competitor’s or potential competitor’s product. We may not prevail in any lawsuits that we initiate and the damages or other remedies awarded if we were to prevail may not be commercially meaningful.

In addition, proceedings to enforce or defend our patents could put our patents at risk of being invalidated, held unenforceable or interpreted narrowly. Such proceedings could also provoke third parties to assert claims against us, including that some or all of the claims in one or more of our patents are invalid or otherwise unenforceable. If any of our patents covering our products are invalidated or found unenforceable, or if a court found that valid, enforceable patents held by third parties covered one or more of our products, our competitive position could be harmed or we could be required to incur significant expenses to enforce or defend our rights. If we initiate lawsuits to protect or enforce our patents, or litigate against third party claims, such proceedings would be expensive and would divert the attention of our management and technical personnel.

The degree of future protection for our proprietary rights is uncertain, and we cannot ensure that:

52

Where we obtain licenses from or collaborate with third parties, in some circumstances, we may not have the right to control the preparation, filing and prosecution of patent applications, or to maintain the patents, covering technology that we license from third parties, or such activities, if controlled by us, may require the input of such third parties. We may also require the cooperation of our licensors and collaborators to enforce any licensed patent rights, and such cooperation may not be provided. Therefore, these patents and applications may not be prosecuted and enforced in a manner consistent with the best interests of our business. Moreover, if we do obtain necessary licenses, we will likely have obligations under those licenses, and any failure to satisfy those obligations could give our licensor the right to terminate the license. Termination of a necessary license, or expiration of licensed patents or patent applications, could have a material adverse impact on our business.

Our inability to effectively protect our proprietary technologies could harm our competitive position.

Although our competitors have utilized and are expected to continue utilizing technologies similar to ours, our success will depend upon our ability to protect and continue to develop proprietary technologies and products and to defend any advantages afforded to us relative to our competitors. If we do not protect our intellectual property adequately, competitors may be able to use our technologies and thereby erode any competitive advantages we may have. For example, patents for our core technology will begin to expire in the United States in 2024, and our patents outside of the United States are expected to remain in effect until between 2024 and 2035. We will be able to protect our proprietary rights from unauthorized use by third parties only to the extent that our proprietary technologies are covered by valid and enforceable patents or are effectively maintained as trade secrets. We have agreements with our employees and selected consultants that obligate them to assign their inventions to us. If the employees and consultants who are parties to these agreements breach or violate the terms of these agreements, including by refusing or being unavailable to sign assignments, oaths, declarations or other documents, we may not have adequate remedies for any such breach or violation, and we could lose our rights in inventions through such breaches or violations. Furthermore, it is possible that technology relevant to our business will be independently developed by a person that is not a party to such an agreement.

The lives of our patents may not be sufficient to effectively protect our products and business.

Patents have a limited lifespan. In the US, the natural expiration of a patent is generally 20 years after its first effective non-provisional filing date. Although various extensions may be available, the life of a patent, and the protection it affords, is limited. Even if patents covering our technologies, products, or product candidates are obtained, once the patent life has expired, we may be open to competition. Patents covering some of our core technology have expired or will expire within the next five years. In addition, although upon issuance in the United States a patent’s life can be increased based on certain delays caused by the USPTO, this increase can be reduced or eliminated based on certain delays caused by the patent applicant during patent prosecution. If we do not have sufficient patent life to protect our technologies, products, and product candidates, our business and results of operations will be adversely affected.

53

Litigation or other proceedings or third-party claims of intellectual property infringement could require us to spend significant time and money and could prevent us from selling our products.

Our commercial success will depend in part on not infringing the patents or violating the other proprietary rights of others. We cannot assure you that our operations do not, or will not in the future, infringe existing or future patents. Our activities may be subject to claims that we infringe or otherwise violate patents owned or controlled by third parties.

Numerous U.S. and foreign patents and pending patent applications exist in our market that are owned by third parties. Our competitors in both the United States and abroad, many of which have substantially greater resources and have made substantial investments in patent portfolios and 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, use and sell our products. We do not always conduct independent reviews of pending patent applications of and patents issued to third parties. Patent applications in the United States and elsewhere are typically published approximately 18 months after the earliest filing for which priority is claimed, with such earliest filing date being commonly referred to as the priority date. Certain U.S. applications that will not be filed outside the U.S. can remain confidential until patents issue. In addition, patent applications in the United States and elsewhere can be pending for many years before issuance, or unintentionally abandoned patents or applications can be revived. Furthermore, pending patent applications that have been published can, subject to certain limitations, be later amended in a manner that could cover our technologies, our products or the use of our products. As such, there may be applications of others now pending or recently revived patents of which we are unaware. These applications may later result in issued patents, or the revival of previously abandoned patents, that will prevent, limit or otherwise interfere with our ability to make, use or sell our products.

The scope of a patent claim is determined by an interpretation of the law, the written disclosure in a patent and the patent’s prosecution history and can involve other factors such as expert opinion. Our interpretation of the relevance or the scope of claims in a patent or a pending application may be incorrect, which may negatively impact our ability to market our products. Further, we may incorrectly determine that our technologies, products, or product candidates are not covered by a third-party patent or may incorrectly predict whether a third party’s pending patent application will issue with claims of relevant scope. Our determination of the expiration date of any patent in the United States or abroad that we consider relevant may be incorrect, which may negatively impact our ability to develop and market our products or product candidates.

Significant litigation regarding patent rights occurs in our industry. Third parties may, in the future, assert claims that we are employing their proprietary technology without authorization, including claims from competitors or from non-practicing entities that have no relevant product revenue and against whom our own patent portfolio may have no deterrent effect. As we continue to commercialize our products in their current or updated forms, launch new products and enter new markets, we expect competitors may claim that one or more of our products infringe their intellectual property rights as part of business strategies designed to impede our successful commercialization and entry into new markets. The large number of patents, the rapid rate of new patent applications and issuances, the complexities of the technology involved, and the uncertainty of litigation may increase the risk of business resources and management’s attention being diverted to patent litigation.

We may become party to future adversarial proceedings regarding our patent portfolio or the patents of third parties. Such proceedings could include supplemental examination or contested post-grant proceedings such as review, reexamination, interference or derivation proceedings before the U.S. Patent and Trademark Office and challenges in U.S. District Court. Patents may be subjected to opposition, post-grant review or comparable proceedings lodged in various foreign, both national and regional, patent offices. The legal threshold for initiating litigation or contested proceedings may be low, so that even lawsuits or proceedings with a low probability of success might be initiated. Litigation and contested proceedings can also be expensive and time-consuming, regardless of the merit of the claims, and our adversaries in these proceedings may have the ability to dedicate substantially greater resources to prosecuting these legal actions than we can.

54

Any lawsuits resulting from such allegations could subject us to significant liability for damages and invalidate our proprietary rights. Any potential intellectual property litigation also could force us to do one or more of the following:

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 and harm our reputation. If we are found to infringe the intellectual property rights of third parties, we could be required to pay substantial damages (which may be increased up to three times of awarded damages) and/or substantial royalties and could be prevented from selling our products unless we obtain a license or are able to redesign our products to avoid infringement. Any such license may not be available on reasonable terms, if at all, and there can be no assurance that we would be able to redesign our products in a way that would not infringe the intellectual property rights of others. Even if such licenses are available, we could incur substantial costs related to royalty payments for licenses obtained from third parties, which could negatively affect our gross margins, and the rights may be non-exclusive, which could give our competitors access to the same technology or intellectual property rights licensed to us. We could encounter delays in product introductions while we attempt to develop alternative methods or products. If we fail to obtain any required licenses or make any necessary changes to our products or technologies, we may have to withdraw existing products from the market or may be unable to commercialize one or more of our products.

If we collaborate with third parties in the development of technology in the future, our collaborators may not properly maintain or defend our intellectual property rights or may use our proprietary information in such a way as to invite litigation that could jeopardize or invalidate our intellectual property or proprietary information or expose us to litigation or potential liability. Further, collaborators may infringe the intellectual property rights of third parties, which may expose us to litigation and potential liability. Also, we may be obligated under our agreements with our collaborators, licensors, suppliers and others to indemnify and hold them harmless for damages arising from intellectual property infringement by us.

In addition, we generally indemnify our customers and international distributors with respect to infringement by our products of the proprietary rights of third parties. Third parties may assert infringement claims against our customers or distributors. These claims may require us to initiate or defend protracted and costly litigation on behalf of our customers or distributors, regardless of the merits of these claims. If any of these claims succeed or settle, we may be forced to pay damages or settlement payments on behalf of our customers or distributors or may be required to obtain licenses for the products they use. If we cannot obtain all necessary licenses on commercially reasonable terms, our customers may be forced to stop using our products.

55

If we are unable to protect the confidentiality of our trade secrets, our business and competitive position could be harmed.

In addition to patent protection, we also rely upon copyright and trade secret protection, unpatented know-how and continuing technological innovation to develop and maintain our competitive position, which we seek to protect through non-disclosure agreements and invention assignment agreements with our employees, consultants and third parties, to protect our confidential and proprietary information. In addition to contractual measures, we try to protect the confidential nature of our proprietary information using commonly accepted physical and technological security measures. Such measures may not provide adequate protection for our proprietary information, for example, in the case of misappropriation of a trade secret by an employee, consultant, customer or third party with authorized access. Our security measures may not prevent an employee, consultant or customer from misappropriating our trade secrets and providing them to a competitor, and recourse we take against such misconduct may not provide an adequate remedy to protect our interests fully. Monitoring unauthorized uses and disclosures is difficult, and we do not know whether the steps we have taken to protect our proprietary technologies will be effective. Unauthorized parties may also attempt to copy or reverse engineer certain aspects of our products that we consider proprietary. Enforcing a claim that a party illegally disclosed or misappropriated a trade secret can be difficult, expensive and time-consuming, and the outcome is unpredictable. Even though we use commonly accepted security measures, the criteria for protection of trade secrets can vary among different jurisdictions.

In addition, trade secrets may be independently developed by others in a manner that could prevent legal recourse by us. Trade secrets will over time be disseminated within the industry through independent development, the publication of journal articles and the movement of personnel skilled in the art from company to company or academic to industry scientific positions. Though our agreements with third parties typically restrict the ability of our advisors, employees, collaborators, licensors, suppliers, third-party contractors and consultants to publish data potentially relating to our trade secrets, our agreements may contain certain limited publication rights. If any of our trade secrets were to be lawfully obtained or independently developed by a competitor, we would have no right to prevent such competitor from using that technology or information to compete with us, which could harm our competitive position. Because from time to time we expect to rely on third parties in the development, manufacture, and distribution of our products and provision of our services, we must, at times, share trade secrets with them. Despite employing the contractual and other security precautions described above, the need to share trade secrets increases the risk that such trade secrets become known by our competitors, are inadvertently incorporated into the technology of others, or are disclosed or used in violation of these agreements. If any of our confidential or proprietary information, such as our trade secrets, were to be disclosed or misappropriated, or if any such information was independently developed by a competitor, our business and competitive position could be harmed.

We may be unable to enforce our intellectual property rights throughout the world.

The laws of some foreign countries do not protect intellectual property rights to the same extent as the laws of the United States. Many companies have encountered significant problems in protecting and defending intellectual property rights in certain foreign jurisdictions. These challenges can be caused by the absence or inconsistency of the application of rules and methods for the establishment and enforcement of intellectual property rights outside of the United States. In addition, the legal systems of some countries, particularly developing countries, do not favor the enforcement of patents and other intellectual property protection, especially those relating to healthcare. This could make it difficult for us to stop infringement of our foreign patents, or the misappropriation of our other intellectual property rights. For example, some foreign countries have compulsory licensing laws under which a patent owner must grant licenses to third parties. In addition, some countries limit the enforceability of patents against third parties, including government agencies or government contractors. In these countries, patents may provide limited or no benefit. Patent protection must ultimately be sought on a country-by-country basis, which is an expensive and time-consuming process with uncertain outcomes. Accordingly, we may choose not to seek patent protection in certain countries, and we will not have the benefit of patent protection in such countries.

Proceedings to enforce our patent rights in foreign jurisdictions could result in substantial costs and divert our efforts and attention from other aspects of our business. Accordingly, our efforts to protect our intellectual property rights in such countries may be inadequate. In addition, changes in the law and legal decisions by courts in the United States and foreign countries may affect our ability to obtain adequate protection for our technology and the enforcement of our intellectual property.

56

Further, the standards applied by the USPTO and foreign patent offices in granting patents are not always applied uniformly or predictably. As such, we do not know the degree of future protection that we will have on our technologies, products, and product candidates. While we will endeavor to try to protect our technologies, products, and product candidates with intellectual property rights such as patents, as appropriate, the process of obtaining patents is time-consuming, expensive and sometimes unpredictable.

Third parties may assert ownership or commercial rights to inventions we develop.

Third parties may in the future make claims challenging the inventorship or ownership of our intellectual property, including studies we commission or reports on the efficacy of our products. In addition, we may face claims by third parties that our agreements with employees, contractors or consultants obligating them to assign intellectual property to us are ineffective or in conflict with prior or competing contractual obligations of assignment, which could result in ownership disputes regarding intellectual property we have developed or will develop and interfere with our ability to capture the commercial value of such intellectual property. Litigation may be necessary to resolve an ownership dispute, and if we are not successful, we may be precluded from using certain intellectual property or may lose our exclusive rights in that intellectual property. Either outcome could harm our business and competitive position.

Third parties may assert that our employees or consultants have wrongfully used or disclosed confidential information or misappropriated trade secrets.

We employ individuals who previously worked with other companies, including our competitors or potential competitors. Although we try to ensure that our employees and consultants do not use the proprietary information or know-how of others in their work for us, we may be subject to claims that we or our employees, consultants or independent contractors have inadvertently or otherwise used or disclosed intellectual property, including trade secrets or other proprietary information, of a former employer or other third party. Litigation may be necessary to defend against these claims. If we fail in defending any such claims or settling those claims, in addition to paying monetary damages or a settlement payment, we may lose valuable intellectual property rights or personnel. 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.

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

Our patent rights may be affected by developments or uncertainty in the patent statute, patent case law or USPTO rules and regulations. There are a number of recent changes to the patent laws that may have a significant impact on our ability to protect our technology and enforce our intellectual property rights. For example, the United States has recently enacted and is currently implementing the America Invents Act of 2011, a wide-ranging patent reform legislation. These changes include provisions that affect the way patent applications will be prosecuted and may also affect patent litigation. As an example, the first to file provisions, which became effective March 2013, mean that the party that is first to file in the United States generally is awarded the patent rights, regardless of who invented first. This could have a negative impact on some of our IP and could increase uncertainties surrounding obtaining and enforcement or defense of our issued patents. Further, the U.S. Supreme Court has ruled on several patent cases in recent years, either narrowing the scope of patent protection available in certain circumstances or weakening the rights of patent owners in certain situations. In addition to increasing uncertainty with regard to our ability to obtain future patents, this combination of events has created uncertainty with respect to the value of patents, once obtained. Depending on decisions by the U.S. Congress, the federal courts and the U.S. Patent and Trademark Office, the laws and regulations governing patents could change in unpredictable ways that would weaken our ability to obtain new patents or to enforce our existing patents or future patents.

57

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

The USPTO and various foreign governmental patent agencies require compliance with a number of procedural, documentary, fee payment and other provisions during the patent process. Periodic maintenance fees, renewal fees, annuity fees and various other governmental fees on patents and/or applications will be due to be paid to the USPTO and various governmental patent agencies outside of the US in several stages over the lifetime of the patents and/or applications. We employ reputable professionals and rely on such third parties to help us comply with these requirements and effect payment of these fees with respect to the patents and patent applications that we own, and if we in-license intellectual property we may have to rely upon our licensors to comply with these requirements and effect payment of these fees with respect to any patents and patent applications that we license. In many cases, an inadvertent lapse can be cured by payment of a late fee or by other means in accordance with the applicable rules. However, there are situations in which noncompliance can result in abandonment or lapse of a patent or patent application, resulting in partial or complete loss of patent rights in the relevant jurisdiction. In such an event, competitors might be able to enter the market earlier than would otherwise have been the case.

If we fail to comply with our obligations under license or technology agreements with third parties, we may be required to pay damages and we could lose license rights that are critical to our business.

We license certain intellectual property, and in the future we may enter into additional agreements that provide us with licenses to valuable intellectual property or technology. These licenses impose various payment obligations on us. If we fail to comply with any of these obligations, we may be required to pay damages and the licensor may have the right to terminate the license. Termination by the licensor could cause us to lose valuable rights, and could prevent us from distributing our products, or inhibit our ability to commercialize future products. Our business could suffer if any current or future licenses terminate, if the licensors fail to abide by the terms of the license, if the licensors fail to enforce licensed patents against infringing third parties, if the licensed patents or other rights are found to be invalid or unenforceable, or if we are unable to enter into necessary licenses on acceptable terms.

Any collaboration arrangements that we may enter into in the future may not be successful, which could adversely affect our ability to develop and commercialize our products.

Any future collaborations that we enter into may not be successful. The success of our collaboration arrangements will depend heavily on the efforts and activities of our collaborators. Collaborations are subject to numerous risks, which may include that:

58

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

Our trademarks or trade names may be challenged, infringed, circumvented or declared generic or descriptive determined to be infringing on other marks. We may not be able to protect our rights to these trademarks and trade names or may be forced to stop using these names, which we need for name recognition by potential partners or customers in our markets of interest. During trademark registration proceedings, we may receive rejections. Although we would be given an opportunity to respond to those rejections, we may be unable to overcome such rejections. In addition, in the USPTO and in comparable agencies in many foreign jurisdictions, third parties are given an opportunity to oppose pending trademark applications and to seek to cancel registered trademarks. Opposition or cancellation proceedings may be filed against our trademarks, and our trademarks may not survive such proceedings. If we are unable to establish name recognition based on our trademarks and trade names, we may not be able to compete effectively and our business may be adversely affected. We may license our trademarks and trade names to third parties, such as distributors. Though these license agreements may provide guidelines for how our trademarks and trade names may be used, a breach of these agreements or misuse of our trademarks and tradenames by our licensees may jeopardize our rights in or diminish the goodwill associated with our trademarks and trade names.

Risks Related to Our Capital Structure

We may need to raise additional capital to fund our existing commercial operations, develop and commercialize new products and expand our operations.

Based on our current business plan, we believe that our cash and cash equivalents as of December 31, 2018 and anticipated revenues from sales of our products will be sufficient to meet our anticipated cash requirements for at least the next 24 months. If our available cash balances, potential future borrowing capacity, and anticipated cash flow from operations are insufficient to satisfy our liquidity requirements, including because of lower demand for our products as a result of the risks described in this Annual Report on Form 10-K, we may seek to sell common or preferred equity or debt securities, enter into an additional credit facility or another form of third-party funding or seek other debt financing. Our present and future funding requirements will depend on many other factors, including:

59

We may also consider raising additional capital in the future to expand our business, to pursue strategic investments, to take advantage of financing opportunities or for other reasons, including to:

Additional capital may not be available to us at such times or in the amounts we need. Even if capital is available, it might be available only on unfavorable terms. Any issuance of additional equity or equity-linked securities could be dilutive to our existing stockholders, and any new equity securities could have rights, preferences and privileges superior to those of holders of our common stock, including the shares of common stock sold in this offering. Debt financing, if available, may involve covenants restricting our operations or our ability to incur additional debt, pay dividends, repurchase our stock, make investments and engage in merger, consolidation or asset sale transactions. If we raise additional funds through collaboration and licensing arrangements with third parties, it may be necessary to relinquish or license some rights to our technologies or products, on terms that are not favorable to us. If access to sufficient capital is not available as and when needed, our business will be materially impaired and we may be required to cease operations, curtail one or more product development or commercialization programs, significantly reduce expenses, sell assets, seek a merger or joint venture partner, file for protection from creditors or liquidate all our assets.

Our ability to use net operating losses to offset future taxable income may be subject to limitations.

As of December 31, 2018, we had federal and state net operating loss carryforwards of $53.8 million and $47.3 million, respectively. The federal and state net operating loss carryforwards will begin to expire, if not utilized, beginning in 2023 and 2020, respectively. These net operating loss carryforwards could expire unused and be unavailable to offset future income tax liabilities. Under the newly enacted federal income tax law, federal net operating losses incurred in 2019 and in future years may be carried forward indefinitely, but the deductibility of such federal net operating losses is limited. It is uncertain how various states will respond to the newly enacted federal tax law. In addition, under Section 382 of the Internal Revenue Code of 1986, as amended, and corresponding provisions of state law, if a corporation undergoes an “ownership change,” which is generally defined as a greater than 50% change, by value, in its equity ownership over a three-year period, the corporation’s ability to use its pre-change net operating loss carryforwards and other pre-change tax attributes to offset its post-change income or taxes may be limited. 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 an ownership change occurs and our ability to use our net operating loss carryforwards is materially limited, it would harm our future operating results by effectively increasing our future tax obligations.

60

The terms of our credit facility place restrictions on our operating and financial flexibility. If we raise additional capital through debt financing, the terms of any new debt could further restrict our ability to operate our business.

In March 2017, we entered into a $35.0 million credit facility with Oxford Finance LLC, or Oxford, that is secured by a lien covering substantially all of our assets, excluding intellectual property. As of December 31, 2018, the outstanding principal balance under the credit facility was $30.0 million. The final $5.0 million tranche under the credit facility became available to us during the second quarter of 2018 upon achievement of a revenue milestone. We had 60 days to notify Oxford if we elected to borrow. As a result of completing our IPO on July 2, 2018 and receiving the net proceeds therefrom, we elected not to borrow the additional $5.0 million, and it is no longer available to us. The credit facility contains customary covenants and events of default applicable to us. The affirmative covenants include, among others, a covenant that requires us to achieve at least 75% of our trailing 12-month forecasted revenues, as measured each month in accordance with a forecast that we provided to Oxford upon signing the agreement and future forecasts that we are required to deliver to the lenders each year for the life of the credit facility. The negative covenants include, among others, restrictions on us transferring collateral, changing businesses, engaging in mergers or acquisitions, incurring additional indebtedness and encumbering collateral. If we default under the credit facility, Oxford may accelerate all of our repayment obligations and take control of our pledged assets, potentially requiring us to renegotiate our agreement on terms less favorable to us or to immediately cease operations. Further, if we are liquidated, Oxford’s right to repayment would be senior to the rights of the holders of our common stock to receive any proceeds from the liquidation. Oxford could declare a default upon the occurrence of any event that it interprets as a material adverse effect as defined under the credit facility, thereby requiring us to repay the loan immediately or to attempt to reverse the declaration of default through negotiation or litigation. Any declaration by Oxford of an event of default could significantly harm our business and prospects and could cause the price of our common stock to decline. If we raise any additional debt financing, the terms of such additional debt could further restrict our operating and financial flexibility.

Risks Related to Government Regulation

Our products and operations are subject to extensive government regulation and oversight both in the United States and abroad, and our failure to comply with applicable requirements could harm our business.

We and our products are subject to extensive regulation in the United States and elsewhere, including by the FDA and its foreign counterparts. The FDA and foreign regulatory agencies regulate, among other things, with respect to medical devices: design, development and manufacturing; testing, labeling, content and language of instructions for use and storage; clinical trials; product safety; marketing, sales and distribution; premarket clearance and approval; record keeping procedures; advertising and promotion; recalls and field safety corrective actions; post-market surveillance, including reporting of deaths or serious injuries and malfunctions that, if they were to recur, could lead to death or serious injury; post-market approval studies; and product import and export.

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 sales. The FDA enforces these regulatory requirements through periodic unannounced inspections. We do not know whether we will pass any future FDA inspections. Failure to comply with applicable regulations could jeopardize our ability to sell our products and result in enforcement actions such as: warning letters; fines; injunctions; civil penalties; termination of distribution; recalls or seizures of products; delays in the introduction of products into the market; total or partial suspension of production; refusal to grant future clearances or approvals; withdrawals or suspensions of current clearances or approvals, resulting in prohibitions on sales of our products; and in the most serious cases, criminal penalties.

We may not receive the necessary clearances or approvals for our future products, and failure to timely obtain necessary clearances or approvals for our future products would adversely affect our ability to grow our business.

An element of our strategy is to continue to upgrade our products, add new features and expand clearance or approval of our current products to new indications. In the United States, before we can market a new medical device, or a new use of, new claim for or significant modification to an existing product, we must first receive either clearance under Section 510(k) of the Federal Food, Drug, and Cosmetic Act, or the FDCA, or approval of a premarket approval application, or PMA, from the FDA, unless an exemption applies. In the 510(k) clearance

61

process, before a device may be marketed, the FDA must determine that a proposed device is “substantially equivalent” to a legally-marketed “predicate” device, which includes a device that has been previously cleared through the 510(k) process, a device that was legally marketed prior to May 28, 1976 (pre-amendments device), a device that was originally on the U.S. market pursuant to an approved PMA and later down-classified, or a 510(k)-exempt device. To be “substantially equivalent,” the proposed device must have the same intended use as the predicate device, and either have the same technological characteristics as the predicate device or have different technological characteristics and not raise different questions of safety or effectiveness than the predicate device. Clinical data are sometimes required to support substantial equivalence. In the PMA process, the FDA must determine that a proposed device is safe and effective for its intended use based, in part, on extensive data, including, but not limited to, technical, pre-clinical, clinical trial, manufacturing and labeling data. Our ability to successfully obtain clearance for any new indications will be dependent on us submitting data as to the successful completion of clinical trials evidencing safety and efficacy. The PMA process is typically required for devices that are deemed to pose the greatest risk, such as life-sustaining, life-supporting or implantable devices. However, some devices are automatically subject to the PMA pathway regardless of the level of risk they pose because they have not previously been classified into a lower risk class by the FDA. Manufacturers of these devices may request that FDA review such devices in accordance with the de novo classification procedure, which allows a manufacturer whose novel device would otherwise require the submission and approval of a PMA prior to marketing to request down-classification of the device on the basis that the device presents low or moderate risk. If the FDA agrees with the down classification, the applicant will then receive authorization to market the device. This device type can then be used as a predicate device for future 510(k) submissions. We initially received marketing authorization of our device through the de novo classification process, and we have made changes to our system through subsequent 510(k) clearances. The process of obtaining regulatory clearances or approvals, or completing the de novo classification process, to market a medical device can be costly and time consuming, and we may not be able to successfully obtain pre-market reviews on a timely basis, if at all.

Modifications to products that are approved through a PMA application generally require FDA approval. Similarly, certain modifications made to products cleared through a 510(k) or authorized through the de novo classification process may require a new 510(k) clearance. Each of the PMA approval, de novo classification and the 510(k) clearance processes can be expensive, lengthy and uncertain. The FDA’s 510(k) clearance process usually takes from three to 12 months but can last longer. The process of obtaining a PMA is much costlier and more uncertain than the 510(k) clearance process and generally takes from one to three years, or even longer, from the time the application is filed with the FDA. In addition, a PMA generally requires the performance of one or more clinical trials.

Despite the time, effort and cost, a device may not be approved or cleared by the FDA. Any delay or failure to obtain necessary regulatory approvals or clearances could harm our business. Furthermore, even if we are granted regulatory clearances or approvals, they may include significant limitations on the indicated uses for the device, which may limit the market for the device.

Any modifications to our existing products may require new 510(k) clearance; however, future modifications may be subject to the substantially more costly, time-consuming and uncertain PMA process. If the FDA requires us to go through a lengthier, more rigorous examination for future products or modifications to existing products than we had expected, product introductions or modifications could be delayed or canceled, which could cause our sales to decline.

The FDA can delay, limit or deny clearance or approval of a device for many reasons, including: we may be unable to demonstrate to the FDA’s satisfaction that the product or modification is substantially equivalent to the proposed predicate device or safe and effective for its intended use; the data from our pre-clinical studies and clinical trials may be insufficient to support clearance or approval, where required; and the manufacturing process or facilities we use may not meet applicable requirements.

Even if granted, a 510(k) clearance, de novo classification, or PMA approval imposes substantial restrictions on how our devices may be marketed or sold, and the FDA continues to place considerable restrictions on our products and operations. For example, the manufacture of medical devices must comply with the FDA’s Quality System Regulation, or QSR. In addition, manufacturers must register their manufacturing facilities, list the products with the FDA, and comply with requirements relating to labeling, marketing, complaint handling, adverse event and medical

62

device reporting, reporting of corrections and removals, and import and export. The FDA monitors compliance with the QSR and these other requirements through periodic inspections. If our facilities or those of our manufacturers or suppliers are found to be in violation of applicable laws and regulations, or if we or our manufacturers or suppliers fail to take satisfactory corrective action in response to an adverse inspection, the regulatory authority could take enforcement action, including any of the following sanctions: untitled letters, warning letters, fines, injunctions, consent decrees and civil penalties; customer notifications or repair, replacement, refunds, detention or seizure of our products; operating restrictions or partial suspension or total shutdown of production; refusing or delaying requests for 510(k) marketing clearance or PMA approvals of new products or modified products; withdrawing 510(k) marketing clearances or PMA approvals that have already been granted; refusing to provide Certificates for Foreign Government; refusing to grant export approval for our products; or pursuing criminal prosecution. Any of these sanctions could impair our ability to produce our products in a cost-effective and timely manner in order to meet our customers’ demands and could have a material adverse effect on our reputation, business, results of operations and financial condition. We may also be required to bear other costs or take other actions that may have a negative impact on our sales and our ability to generate profits.

In addition, the FDA may change its clearance and approval policies, adopt additional regulations or revise existing regulations, or take other actions, which may prevent or delay approval or clearance of our future products under development or impact our ability to modify our currently cleared products on a timely basis. Such policy or regulatory changes could impose additional requirements upon us that could delay our ability to obtain new 510(k) clearances, increase the costs of compliance or restrict our ability to maintain our current clearances. We also cannot predict the likelihood, nature or extent of government regulation that may arise from future legislation or administrative or executive action, either in the United States or abroad. For example, certain policies of the Trump administration may impact our business and industry. Namely, the Trump administration has taken several executive actions, including the issuance of a number of Executive Orders, that could impose significant burdens on, or otherwise materially delay, the FDA’s ability to engage in routine regulatory and oversight activities such as implementing statutes through rulemaking, issuance of guidance, and review and approval of marketing applications. It is difficult to predict how these executive actions, including the Executive Orders, will be implemented, and the extent to which they will impact the FDA’s ability to exercise its regulatory authority. If these executive actions impose constraints on FDA’s ability to engage in oversight and implementation activities in the normal course, our business may be negatively impacted.

In order to sell our products in member countries of the EEA our products must comply with the essential requirements of the EU Medical Devices Directive (Council Directive 93/42/EEC). Compliance with these requirements is a prerequisite to be able to affix the CE Mark to our products, without which they cannot be sold or marketed in the EEA. To demonstrate compliance with the essential requirements we must undergo a conformity assessment procedure, which varies according to the type of medical device and its classification. Except for low-risk medical devices (Class I non-sterile, non-measuring devices), where the manufacturer can issue an EC Declaration of Conformity based on a self-assessment of the conformity of its products with the essential requirements of the EU Medical Devices Directive, a conformity assessment procedure requires the intervention of an organization accredited by a Member State of the EEA to conduct conformity assessments, or a Notified Body. Depending on the relevant conformity assessment procedure, the Notified Body would typically audit and examine the technical file and the quality system for the manufacture, design and final inspection of our devices. The Notified Body issues a certificate of conformity following successful completion of a conformity assessment procedure conducted in relation to the medical device and its manufacturer and their conformity with the essential requirements. This certificate entitles the manufacturer to affix the CE Mark to its medical devices after having prepared and signed a related EC Declaration of Conformity.

As a general rule, demonstration of conformity of medical devices and their manufacturers with the essential requirements must be based, among other things, on the evaluation of clinical data supporting the safety and performance of the products during normal conditions of use. Specifically, a manufacturer must demonstrate that the device achieves its intended performance during normal conditions of use, that the known and foreseeable risks, and any adverse events, are minimized and acceptable when weighed against the benefits of its intended performance, and that any claims made about the performance and safety of the device are supported by suitable evidence. If we fail to remain in compliance with applicable European laws and directives, we would be unable to continue to affix the CE Mark to our surgical systems, which would prevent us from selling them within the EEA.

63

We or our distributors will also need to obtain regulatory approval in other foreign jurisdictions in which we plan to market and sell our products, and we or they may not obtain such approvals as necessary to commercialize our products in those territories.

Modifications to our products may require new 510(k) clearances or PMA approvals, and may require us to cease marketing or recall the modified products until clearances are obtained.

Any modification to a 510(k)-cleared product that could significantly affect its safety or effectiveness, or that would constitute a major change in its intended use, design or manufacture, requires a new 510(k) clearance or, possibly, approval of a PMA. The FDA requires every manufacturer to make this determination in the first instance, but the FDA may review any manufacturer’s decision. The FDA may not agree with our decisions regarding whether new clearances or approvals are necessary. We have made modifications to our products in the past and have determined based on our review of the applicable FDA regulations and guidance that in certain instances new 510(k) clearances were not required. We may make similar modifications or add additional features in the future that we believe do not require a new 510(k) clearance or approval of a PMA. If the FDA disagrees with our determination and requires us to submit new 510(k) notifications or PMAs for modifications to our previously cleared products for which we have concluded that new clearances or approvals are unnecessary, we may be required to cease marketing or to recall the modified product until we obtain clearance or approval, and we may be subject to significant regulatory fines or penalties. In addition, the FDA may not approve or clear our products for the indications that are necessary or desirable for successful commercialization or could require clinical trials to support any modifications. Any delay or failure in obtaining required clearances or approvals would adversely affect our ability to introduce new or enhanced products in a timely manner, which in turn would harm our future growth.

Our products must be manufactured in accordance with federal and state regulations, and we could be forced to recall our installed systems or terminate production if we fail to comply with these regulations.

The methods used in, and the facilities used for, the manufacture of our products must comply with the FDA’s Quality System Regulation, or QSR, which is a complex regulatory scheme that covers the procedures and documentation of the design, testing, production, process controls, quality assurance, labeling, packaging, handling, storage, distribution, installation, servicing and shipping of medical devices. Furthermore, we are required to verify that our suppliers maintain facilities, procedures and operations that comply with our quality standards and applicable regulatory requirements. The FDA enforces the QSR through periodic announced or unannounced inspections of medical device manufacturing facilities, which may include the facilities of subcontractors. Our products are also subject to similar state regulations and various laws and regulations of foreign countries governing manufacturing.

We or our third-party manufacturers may not take the necessary steps to comply with applicable regulations, which could cause delays in the delivery of our products. In addition, failure to comply with applicable FDA requirements or later discovery of previously unknown problems with our products or manufacturing processes could result in, among other things: warning letters or untitled letters; fines, injunctions or civil penalties; suspension or withdrawal of approvals or clearances; seizures or recalls of our products; total or partial suspension of production or distribution; administrative or judicially imposed sanctions; the FDA’s refusal to grant pending or future clearances or approvals for our products; clinical holds; refusal to permit the import or export of our products; and criminal prosecution of us or our employees.

Any of these actions could significantly and negatively impact supply of our products. If any of these events occurs, our reputation could be harmed, we could be exposed to product liability claims and we could lose customers and suffer reduced revenues and increased costs.

If treatment guidelines for the psychiatric conditions we are targeting change or the standard of care evolves, we may need to redesign and seek new marketing authorization from the FDA for one or more of our products.

If treatment guidelines for the psychiatric conditions we are targeting or the standard of care for such conditions evolves, we may need to redesign the applicable product and seek new clearances or approvals from the FDA. Our 510(k) clearances from the FDA are based on current treatment guidelines. If treatment guidelines change so that different treatments become desirable, the clinical utility of one or more of our products could be diminished and our business could suffer.

64

The misuse or off-label use of our products may harm our reputation in the marketplace, result in injuries that lead to product liability suits or result in costly investigations, fines or sanctions by regulatory bodies if we are deemed to have engaged in the promotion of these uses, any of which could be costly to our business.

Our product has been authorized for marketing by the FDA for a specific indication. We train our commercial organization and distributors outside the United States to not promote our products for uses outside of the FDA-cleared indications for use, known as “off-label uses.” We cannot, however, prevent a psychiatrist from using our products off-label, when in the psychiatrist’s independent professional medical judgment, he or she deems it appropriate. There may be increased risk of injury to patients if psychiatrists attempt to use our products off-label. Furthermore, the use of our products for indications other than those cleared by the FDA or approved by any foreign regulatory body may not effectively treat such conditions, which could harm our reputation in the marketplace among psychiatrists and patients.

If the FDA or any foreign regulatory body 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 or imposition of an untitled letter, which is used for violators that do not necessitate a warning letter, injunction, seizure, civil fine or criminal penalties. It is also possible that other federal, state or foreign enforcement authorities might take action under other regulatory authority.

Our products may cause or contribute to adverse medical events that we are required to report to the FDA, and if we fail to do so, we would be subject to sanctions that could harm our reputation, business, financial condition and results of operations. The discovery of serious safety issues with our products, or a recall of our products either voluntarily or at the direction of the FDA or another governmental authority, could have a negative impact on us.

We are subject to the FDA’s medical device reporting regulations and similar foreign regulations, which require us to report to the FDA when we receive or become aware of information that reasonably suggests that one or more of our products may have caused or contributed to a death or serious injury or malfunctioned in a way that, if the malfunction were to recur, it could cause or contribute to a death or serious injury. The timing of our obligation to report is triggered by the date we become aware of the adverse event as well as the nature of the event. We may fail to report adverse events of which we become aware within the prescribed timeframe. We may also fail to recognize that we have become aware of a reportable adverse event, especially if it is not reported to us as an adverse event or if it is an adverse event that is unexpected or removed in time from the use of the product. If we fail to comply with our reporting obligations, the FDA could take action, including warning letters, untitled letters, administrative actions, criminal prosecution, imposition of civil monetary penalties, revocation of our device clearance, seizure of our products or delay in clearance of future products.

The FDA and foreign regulatory bodies have the authority to require the recall of commercialized products in the event of material deficiencies or defects in design or manufacture of a product or in the event that a product poses an unacceptable risk to health. The FDA’s authority to require a recall must be based on a finding that there is reasonable probability that the device could cause serious injury or death. We may also choose to voluntarily recall a product if any material deficiency is found. A government-mandated or voluntary recall by us could occur as a result of an unacceptable risk to health, component failures, malfunctions, manufacturing defects, labeling or design deficiencies, packaging defects or other deficiencies or failures to comply with applicable regulations. Product defects or other errors may occur in the future.

Depending on the corrective action we take to redress a product’s deficiencies or defects, the FDA may require, or we may decide, that we will need to obtain new approvals or clearances for the device before we may market or distribute the corrected device. Seeking such approvals or clearances may delay our ability to replace the recalled devices in a timely manner. Moreover, if we do not adequately address problems associated with our devices, we may face additional regulatory enforcement action, including FDA warning letters, product seizure, injunctions, administrative penalties or civil or criminal fines.

65

Companies are required to maintain certain records of recalls and corrections, even if they are not reportable to the FDA. We may initiate voluntary withdrawals or corrections for our products in the future that we determine do not require notification of the FDA. If the FDA disagrees with our determinations, it could require us to report those actions as recalls and we may be subject to enforcement action. A future recall announcement could harm our reputation with customers, potentially lead to product liability claims against us and negatively affect our sales.

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

If we or our distributors do not obtain and maintain international regulatory registrations or approvals for our products, we will be unable to market and sell our products outside of the United States.

Sales of our products outside of the United States are subject to foreign regulatory requirements that vary widely from country to country. In addition, the FDA regulates exports of medical devices from the United States. While the regulations of some countries may not impose barriers to marketing and selling our products or only require notification, others require that we or our distributors obtain the approval of a specified regulatory body. Complying with foreign regulatory requirements, including obtaining registrations or approvals, can be expensive and time-consuming, and we or our distributors may not receive regulatory approvals in each country in which we plan to market our products or we may be unable to do so on a timely basis. The time required to obtain registrations or approvals, if required by other countries, may be longer than that required for FDA clearance, and requirements for such registrations, clearances or approvals may significantly differ from FDA requirements. If we modify our products, we or our distributors may need to apply for additional regulatory approvals before we are permitted to sell the modified product. In addition, we may not continue to meet the quality and safety standards required to maintain the authorizations that we or our distributors have received. If we or our distributors are unable to maintain our authorizations in a particular country, we will no longer be able to sell the applicable product in that country.

Regulatory clearance or approval by the FDA does not ensure clearance or approval by regulatory authorities in other countries, and clearance or approval by one or more foreign regulatory authorities does not ensure clearance or approval by regulatory authorities in other foreign countries or by the FDA. However, a failure or delay in obtaining regulatory clearance or approval in one country may have a negative effect on the regulatory process in others.

We are subject to certain federal, state and foreign fraud and abuse laws, health information privacy and security laws and transparency laws, which, if violated, could subject us to substantial penalties. Additionally, any challenge to or investigation into our practices under these laws could cause adverse publicity and be costly to respond to, and thus could harm our business.

There are numerous U.S. federal and state, as well as foreign, laws pertaining to healthcare fraud and abuse, including anti-kickback, false claims and physician transparency laws. Our business practices and relationships with providers, patients and third-party payors are subject to scrutiny under these laws. We may also be subject to patient information privacy and security regulation by both the federal government and the states and foreign jurisdictions in which we conduct our business. The healthcare laws and regulations that may affect our ability to operate include:

66

67

These laws and regulations, among other things, constrain our business, marketing and other promotional activities by limiting the kinds of financial arrangements, including sales programs, we may have with psychiatrists or other potential purchasers of our products. We have also entered into consulting agreements with physicians, which are subject to these laws. Further, while we do not submit claims and our customers will make the ultimate decision on how to submit claims, we may provide reimbursement guidance and support regarding our products. Due to the breadth of these laws, the narrowness of statutory exceptions and regulatory safe harbors available, and the range of interpretations to which they are subject, it is possible that some of our current or future practices might be challenged under one or more of these laws.

To enforce compliance with healthcare regulatory laws, certain enforcement bodies have recently increased their 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. Responding to investigations can be time-and resource-consuming and can divert management’s attention from the business. Any such investigation or settlement could increase our costs or otherwise have an adverse effect on our business. Even an unsuccessful challenge or investigation into our practices could cause adverse publicity and be costly to respond to.

If our operations are found to be in violation of any of the healthcare laws or regulations described above or any other healthcare regulations that apply to us, we may be subject to penalties, including administrative, civil and criminal penalties, damages, fines, disgorgement, exclusion from participation in government healthcare programs, such as Medicare and Medicaid, imprisonment, additional reporting obligations and oversight if we becomes subject to a corporate integrity agreement or other agreement to resolve allegations of non-compliance with these laws, reputational harm, diminished profits and future earnings, and the curtailment or restructuring of our operations, any of which could adversely affect our ability to operate our business and pursue our strategy.

Healthcare policy changes, including recently enacted legislation reforming the U.S. healthcare system, could harm our cash flows, financial condition and results of operations.

From time to time, legislation is drafted and introduced in Congress that could significantly change the statutory provisions governing the regulation of medical devices. 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 statutes, regulations, revisions, or reinterpretations of existing regulations may impose additional costs, lengthen review times of any future products, or make it more difficult to manufacture, market or distribute our products. We cannot determine what effect changes in regulations, statutes, legal interpretation or policies, when and if promulgated, enacted or adopted may have on our business in the future.

For example, in March 2010, the PPACA was enacted in the United States, which made a number of substantial changes in the way healthcare is financed by both governmental and private insurers. Among other ways in which it may impact our business, the PPACA:

68

Some of the provisions of the PPACA have yet to be implemented, and there have been judicial and Congressional challenges to certain aspects of the PPACA, as well as recent efforts by the Trump administration to repeal or replace certain aspects of the PPACA. Since January 2017, President Trump has signed two Executive Orders and other directives designed to delay the implementation of certain provisions of the PPACA or otherwise circumvent some of the requirements for health insurance mandated by the PPACA. Concurrently, Congress has considered legislation that would repeal or repeal and replace all or part of the PPACA. While Congress has not passed comprehensive repeal legislation, two bills affecting the implementation of certain taxes under the PPACA have been signed into law. The Tax Cuts and Jobs Act of 2017, or the Tax Act, includes a provision repealing, 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.” The 2018 Appropriations Resolution delayed the implementation of certain PPACA-mandated fees, including, without limitation, the medical device excise tax. The Bipartisan Budget Act of 2018, or the BBA, among other things, amends the PPACA, effective January 1, 2019, to close the coverage gap in most Medicare drug plans, commonly referred to as the “donut hole”. In July 2018, CMS published a final rule permitting further collections and payments to and from certain PPACA qualified health plans and health insurance issuers under the PPACA risk adjustment program in response to the outcome of federal district court litigation regarding the method CMS uses to determine this risk adjustment. On December 14, 2018, a U.S. District Court Judge in the Northern District of Texas, or Texas District Court Judge, ruled that the individual mandate is a critical and inseverable feature of the PPACA, and therefore, because it was repealed as part of the Tax Act, the remaining provisions of the PPACA are invalid as well. While the Texas District Court Judge, as well as the Trump administration and CMS, have stated that the ruling will have no immediate effect, it is unclear how this decision, subsequent appeals, if any, and other efforts to repeal and replace the PPACA will impact the PPACA. As a result, there is significant uncertainty regarding future healthcare reform and its impact on our operations.

In addition, other legislative changes have been proposed and adopted since the Affordable Care Act was enacted. On August 2, 2011, the Budget Control Act of 2011 was signed into law, which, among other things, created the Joint Select Committee on Deficit Reduction to recommend to Congress proposals for spending reductions. The Joint Select Committee did not achieve a targeted deficit reduction of at least $1.2 trillion for the years 2013 through 2021, triggering the legislation’s automatic reduction to several government programs. This 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, including the BBA, will remain in effect through 2027 unless additional Congressional action is taken. Additionally, on January 2, 2013, President Obama signed into law the American Taxpayer Relief Act of 2012 which, among other things, further reduced Medicare payments to several types of providers, including hospitals, and increased the statute of limitations period for the government to recover overpayments to providers from three to five years. Further, the Medicare Access and CHIP Reauthorization Act of 2015, enacted on April 16, 2015, or MACRA, repealed the formula by which Medicare made annual payment adjustments to physicians and replaced the former formula with fixed annual updates and a new system of incentive payments scheduled to begin in 2019 that are based on various performance measures and physicians’ participation in alternative payment models such as accountable care organizations.

Recently there has been heightened governmental scrutiny over the manner in which manufacturers set prices for their marketed products, which has resulted in several U.S. Congressional inquiries and proposed federal legislation designed to, among other things, bring more transparency to product pricing, reduce the cost of certain products under Medicare, review the relationship between pricing and manufacturer patient programs, and reform government program reimbursement methodologies. At the state level, individual states in the United States are also increasingly passing legislation and implementing regulations designed to control product pricing, including price or patient reimbursement constraints, discounts, restrictions on certain product access and marketing cost disclosure and transparency measures.

We expect additional state and federal healthcare reform measures to be adopted in the future, any of which could limit the amounts that federal and state governments will pay for healthcare products and services, which could result in reduced demand for our products or additional pricing pressure.

Risks Related to Ownership of Our Common Stock

The price of our common stock may be volatile.

The trading price of our common stock may be highly volatile and could be subject to wide fluctuations in response to various factors, some of which are beyond our control. Factors that could cause volatility in the market price of our common stock include, but are not limited to:

In addition, the stock markets in general, and the markets for companies like ours in particular, have from time to time experienced extreme volatility that has been often unrelated to the operating performance of the company. These broad market and industry fluctuations may negatively impact the price or liquidity of our common stock, regardless of our operating performance.

Moreover, because of these fluctuations, comparing our operating results on a period-to-period basis may not be meaningful. You should not rely on our past results as an indication of our future performance. This variability and unpredictability could also result in our failing to meet the expectations of industry or financial analysts or investors for any period. If our revenues or operating results fall below the expectations of analysts or investors or below any forecasts we may provide to the market, or if the forecasts we provide to the market are below the expectations of analysts or investors, the price of our common stock could decline substantially. Such a stock price decline could occur even when we have met any previously publicly stated revenues or earnings forecasts that we may provide.

70

We may be subject to securities litigation, which is expensive and could divert our management’s attention.

In the past, companies that have experienced volatility in the market price of their securities have been subject to securities class action litigation. We may be the target of this type of litigation in the future. Regardless of the merits or the ultimate results of such litigation, securities litigation brought against us could result in substantial costs and divert our management’s attention from other business concerns.

We are an “emerging growth company” and the reduced disclosure requirements applicable to emerging growth companies could make our common stock less attractive to investors.

We are an “emerging growth company,” as defined in the JOBS Act. We may remain an emerging growth company until as late as December 31, 2023, though we may cease to be an emerging growth company earlier under certain circumstances, including (i) if the market value of our common stock that is held by non-affiliates exceeds $700 million as of any June 30, in which case we would cease to be an emerging growth company as of the following December 31, or (ii) if our gross revenues exceeds $1.07 billion in any fiscal year. “Emerging growth companies” may take advantage of certain exemptions from various reporting requirements that are applicable to other public companies, including not being required to comply with the auditor attestation requirements of Section 404 of the Sarbanes-Oxley Act, reduced disclosure obligations regarding executive compensation in our periodic reports and proxy statements and exemptions from the requirements of holding a nonbinding advisory vote on executive compensation and stockholder approval of any golden parachute payments not previously approved. Investors could find our common stock less attractive because we may rely on these exemptions. If some investors find our common stock less attractive as a result, there may be a less active trading market for our common stock and our stock price may be more volatile.

In addition, Section 102 of the JOBS Act also provides that an emerging growth company can take advantage of the extended transition period provided in Section 7(a)(2)(B) of the Securities Act of 1933, as amended, or the Securities Act, for complying with new or revised accounting standards. An emerging growth company can therefore delay the adoption of certain accounting standards until those standards would otherwise apply to private companies. We are choosing not to “opt out” of such extended transition period, and as a result, we will not comply with new or revised accounting standards on the relevant dates on which adoption of such standards is required for non-emerging growth companies.

Future sales of our common stock or securities convertible or exchangeable for our common stock may cause our stock price to decline.

If our stockholders or option holders sell, or indicate an intention to sell, substantial amounts of our common stock in the public market, the price of our common stock could decline. The perception in the market that these sales may occur could also cause the price of our common stock to decline.

Shares of common stock that are either subject to outstanding options, or are outstanding but subject to vesting or reserved for future issuance under our 2018 Equity Incentive Plan, or the 2018 Plan, will become eligible for sale in the public market to the extent permitted by the provisions of various vesting schedules, Rule 144 and Rule 701 under the Securities Act. We have also filed a registration statement permitting certain shares of common stock issued under our 2003 Stock Incentive Plan, or the 2003 Plan, and shares of common stock issued pursuant to the 2018 Plan or our 2018 Employee Stock Purchase Plan, or the 2018 ESPP, to be freely resold by plan participants in the public market, subject to applicable vesting schedules and, for shares held by directors, executive officers and other affiliates, volume limitations under Rule 144 under the Securities Act. Both the 2018 Plan and the 2018 ESPP contain provisions for the annual increase of the number of shares reserved for issuance under such plans, which shares we also intend to register. If the shares we may issue from time to time under the 2003 Plan, the 2018 Plan or the 2018 ESPP are sold, or if it is perceived that they will be sold, by the award recipients in the public market, the price of our common stock could decline.  

Approximately 11,099,375 shares of common stock are entitled to rights with respect to registration under the Securities Act. Such registration would result in these shares becoming fully tradable without restriction under the Securities Act when the applicable registration statement is declared effective. Sales of such shares could cause the price of our common stock to decline.

71

Our principal stockholders and management own a significant percentage of our stock and are able to exert control over matters subject to stockholder approval.

As of February 28, 2019, our officers and directors, together with holders of 5% or more of our outstanding common stock and their respective affiliates, beneficially owned approximately 39.0% of our common stock. Accordingly, these stockholders have an influence over the outcome of corporate actions requiring stockholder approval, including the election of directors, mergers, consolidation or sale of all or substantially all of our assets or any other significant corporate transaction. The interests of these stockholders may not be the same as or may even conflict with your interests. For example, these stockholders could attempt to delay or prevent a change in control of the company, even if such a change in control would benefit our other stockholders, which could deprive our stockholders of an opportunity to receive a premium for their common stock as part of a sale of the company or our assets and might affect the prevailing price of our common stock. The significant concentration of stock ownership may negatively impact the price of our common stock due to investors’ perception that conflicts of interest may exist or arise.

We are obligated to develop and maintain proper and effective internal controls over financial reporting and any failure to maintain the adequacy of these internal controls may adversely affect investor confidence in our company and the value of our common stock.

As a public company, the Sarbanes-Oxley Act requires that we maintain effective disclosure controls and procedures and internal control over financial reporting. We have developed disclosure controls and other procedures that are designed to ensure that information required to be disclosed by us in the reports that we file with the SEC is recorded, processed, summarized and reported within the time periods specified in SEC rules and regulations, and that information required to be disclosed in reports under the Securities Exchange Act of 1934, or the Exchange Act, is communicated to our principal executive and financial officers. Our current controls and any new controls that we develop may become inadequate and weaknesses in our internal control over financial reporting may be discovered in the future. Any failure to maintain effective controls could negatively impact the results of periodic management evaluations and annual independent registered public accounting firm attestation reports regarding the effectiveness of our internal control over financial reporting that we will be required to include in periodic reports we file with the SEC under Section 404 of the Sarbanes-Oxley Act, harm our operating results, cause us to fail to meet our reporting obligations or result in a restatement of our prior period financial statements. In the event that we are not able to demonstrate compliance with the Sarbanes-Oxley Act, that our internal control over financial reporting is perceived as inadequate or that we are unable to produce timely or accurate financial statements, investors may lose confidence in our operating results and the price of our common stock could decline. In addition, if we are unable to continue to meet these requirements, we may be unable to remain listed on the Nasdaq Global Market.

Our independent registered public accounting firm will not be required to formally attest to the effectiveness of our internal control over financial reporting until the later of our second annual report or the first annual report we are required to file with the SEC following the date we are no longer an “emerging growth company,” as defined in the JOBS Act, depending on whether we choose to rely on certain exemptions set forth in the JOBS Act.

Provisions of our amended and restated charter documents or Delaware law could delay or prevent an acquisition of the company, even if the acquisition would be beneficial to our stockholders, which could make it more difficult for you to change management.

Provisions in our amended and restated certificate of incorporation and our amended and restated bylaws may discourage, delay or prevent a merger, acquisition or other change in control that stockholders may consider favorable, including transactions in which stockholders might otherwise receive a premium for their shares. In addition, these provisions may frustrate or prevent any attempt by our stockholders to replace or remove our current management by making it more difficult to replace or remove our board of directors. These provisions include:

72

In addition, Delaware law prohibits a publicly held Delaware corporation from engaging in a business combination with an interested stockholder, generally a person who, together with its affiliates, owns, or within the last three years has owned, 15% or more of our voting stock, for a period of three years after the date of the transaction in which the person became an interested stockholder, unless the business combination is approved in a prescribed manner. Accordingly, Delaware law may discourage, delay or prevent a change in control of our company.

Provisions in our charter documents and other provisions of Delaware law could limit the price that investors are willing to pay in the future for shares of our common stock.

Our amended and restated certificate of incorporation provides 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, to the fullest extent permitted by law, the Court of Chancery of the State of Delaware is the exclusive forum for (i) any derivative action or proceeding brought on our behalf, other than an action or suit to enforce a duty or liability created by the Securities Exchange Act of 1934 or any other claim for which the federal courts have exclusive jurisdiction, (ii) any action asserting a claim of breach of a fiduciary duty or other wrongdoing by any of our directors, officers, employees or agents to us or our stockholders, (iii) any action asserting a claim arising pursuant to any provision of the DGCL or our amended and restated certificate of incorporation or amended and restated bylaws, (iv) any action to interpret, apply, enforce or determine the validity of our amended and restated certificate of incorporation or amended and restated bylaws or (v) any action asserting a claim governed by the internal affairs doctrine. Our amended and restated certificate of incorporation further provides 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. 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 such lawsuits against us and our directors, officers and other employees. Some companies that adopted a similar federal district court forum selection provision are currently subject to a suit in the Chancery Court of Delaware by stockholders who assert that the provision is not enforceable. If a court were to find either choice of forum provision contained in our amended and restated certificate of incorporation to be inapplicable or unenforceable in an action, we may incur additional costs associated with resolving such action in other jurisdictions, which could harm our business.

We do not anticipate paying any cash dividends on our common stock in the foreseeable future; therefore, capital appreciation, if any, of our common stock will be your sole source of gain for the foreseeable future.

We have never declared or paid any cash dividends on our common stock and do not intend to do so in the foreseeable future. We currently intend to retain all available funds and any future earnings to finance the growth and development of our business. In addition, the terms of our credit agreements contain, and the terms of any future credit agreements we may enter into may contain, terms prohibiting or limiting the amount of dividends that may be declared or paid on our common stock. As a result, capital appreciation, if any, of our common stock will be your sole source of gain for the foreseeable future.

73

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

The trading market for our common stock depends, to some extent, on the research and reports that securities or industry analysts publish about us and our business. We do not have any control over these analysts. If one or more of the analysts who cover us downgrade our common stock or change their opinion of our common stock, our stock price would likely decline. If one or more of these analysts cease to cover us or fail to regularly publish reports on us, we could lose visibility in the financial markets, which could cause our stock price or trading volume to decline.

None.

We occupy an approximately 32,000 square foot facility in Malvern, Pennsylvania, under a lease that ends in February 2021, for our corporate headquarters, which includes office and warehouse space. We have an option to extend the lease for an additional five-year term followed by a three-year additional term. We believe that our existing facilities are adequate to meet our needs for the foreseeable future.

The Company is subject from time to time to various claims and legal actions arising during the ordinary course of its business. Management believes that there are currently no claims or legal actions that would reasonably be expected to have a material adverse effect on the Company’s results of operations, financial condition, or cash flows.

Not applicable.

PART II

Stock Price

Our common stock has been publicly traded on the Nasdaq Global Market under the symbol “STIM” since June 28, 2018. Prior to that time, there was no public market for our common stock. The shares of our common stock sold in our initial public offering (IPO) on June 27, 2018 were priced at $17.00 per share. The following table sets forth the high and low sales price of our common stock, as reported by the Nasdaq Global Market for the period indicated:

Holders 

As of February 28, 2019, there were approximately 95 holders of record of our common stock, solely based upon the count our transfer agent provided to us as of that date.

Dividends

We have never declared or paid, and do not anticipate declaring or paying, in the foreseeable future, any cash dividends on our common stock. We currently intend to retain all available funds and any future earnings to support our operations and finance the growth and development of our business. In addition, under the terms of our loan and security agreement with Oxford Finance LLC, we may not declare or pay any cash dividends or distributions, subject to certain exceptions, without the consent of Oxford Finance LLC. Any future determination related to our dividend policy will be made at the discretion of our board of directors and will depend upon, among other factors, our results of operations, financial condition, capital requirements, the consent of Oxford Finance LLC, other contractual restrictions, business prospects and other factors our board of directors may deem relevant.

Unregistered Sales of Securities

None.

Warrants

In August 2016, March 2017 and December 2017, we issued preferred stock warrants to Oxford Finance LLC, each of which was immediately exercisable for 588,498 shares of our Series F convertible preferred stock at an exercise price of $0.3356 per share. The August 2016, March 2017 and December 2017 warrants expire on August 31, 2023, March 28, 2024 and December 27, 2024, respectively, if not earlier exercised.

Immediately prior to the closing of our IPO on July 2, 2018, all of our outstanding Series E and Series F convertible preferred stock warrants automatically converted into common stock warrants. Each of these August 2016, March 2017 and December 2017 Series F convertible preferred stock warrants converted into warrants to purchase 20,303 shares of our common stock at an exercise price of $9.73 per share.

None of the foregoing transactions involved any underwriters, underwriting discounts or commissions, or any public offering. The sales of the above securities were deemed to be exempt from registration under the Securities Act in reliance upon Section 4(2) of the Securities Act (or Regulation D or Regulation S promulgated thereunder), or Rule 701 promulgated under Section 3(b) of the Securities Act as transactions by an issuer not involving any public offering or pursuant to benefit plans and contracts relating to compensation as provided under Rule 701. The recipients of the securities in each of these transactions represented their intentions to acquire the securities for investment only and not with a view to or for sale in connection with any distribution thereof, and appropriate legends were placed upon the stock certificates issued in these transactions.

75

Use of Proceeds

Our IPO was effected through a Registration Statement on Form S-1 (File No. 333-225307) that was declared effective by the SEC on June 27, 2018. On June 27, 2018, 6,325,000 shares of our common stock were sold at a public offering price of $17.00 per share, for aggregate gross proceeds of $107.5 million. As of the date of filing this Annual Report on Form 10-K, the offering has terminated, and all of the securities registered pursuant to the offering were sold prior to termination. Piper Jaffray & Co. and William Blair & Company, L.L.C. acted as joint book-running managers, Canaccord Genuity LLC acted as lead manager and BTIG, LLC and JMP Securities LLC acted as co-managers for the IPO.

On July 2, 2018, received net proceeds $96.5 million after deducting underwriting discounts, commissions and other offering expenses paid by us. The funds shall be used in a manner consistent with the use of proceeds from the IPO as described in our IPO prospectus under the caption “Use of Proceeds,” which has not materially changed since the filing of our IPO prospectus with the SEC on June 29, 2018.

Equity Compensation Plans

The following table details information regarding our existing equity compensation plans as of December 31, 2018:

Overview

We are a commercial stage medical technology company focused on designing, developing and marketing products that improve the quality of life for patients who suffer from psychiatric disorders. Our first commercial product, the NeuroStar Advanced Therapy System, is a non-invasive and non-systemic office-based treatment that uses transcranial magnetic stimulation, or TMS, to create a pulsed, MRI-strength magnetic field that induces electrical currents designed to stimulate specific areas of the brain associated with mood. The system is cleared by the United States Food and Drug Administration, or FDA, to treat adult patients with major depressive disorder, or MDD, that have failed to achieve satisfactory improvement from prior antidepressant medication in the current MDD episode. NeuroStar Advanced Therapy is safe, clinically effective, reproducible and precise and we believe is supported by the largest clinical data set of any competing TMS system. We believe we are the market leader in TMS therapy based on our U.S. installed base of 907 active NeuroStar Advanced Therapy Systems in approximately 707 psychiatrist offices as of December 31, 2018 and the estimated 62,900 patients treated with approximately 2.3 million of our treatment sessions through such date. We generated revenues of $52.8 million and $40.4 million for the years ended December 31, 2018 and 2017, respectively.

We designed the NeuroStar Advanced Therapy System as a non-invasive therapeutic alternative to treat patients who suffer from MDD and to address many of the key limitations of existing treatment options. We generate revenues from initial capital sales of our systems, sales of our recurring treatment sessions and from service and repair and extended warranty contracts. We derive the majority of our revenues from recurring treatment sessions. For the year ended December 31, 2018, revenues from sales of our treatment sessions and NeuroStar Advanced Therapy Systems represented 69% and 28% of our U.S. revenues, respectively.  For the year ended December 31, 2017, revenues from sales of our treatment sessions and NeuroStar Advanced Therapy Systems represented 71% and 25% of our U.S. revenues, respectively.

We currently sell our NeuroStar Advanced Therapy System and recurring treatment sessions in the United States through our sales and customer support team, which was comprised of 133 people as of December 31, 2018. Our sales force primarily targets 15,100 psychiatrists at 3,600 high-decile psychiatric practices that we estimate, based on data from Symphony Health and our own internal estimates, treat approximately 33% of the total MDD patients in the United States who meet our labeled indication and are insured. We expect to continue to expand our direct sales and customer support team to further penetrate the market by demonstrating the benefits of our NeuroStar Advanced Therapy to psychiatrists and their MDD patients. Some of our customers have and may purchase more than one NeuroStar Advanced Therapy System. Based on our commercial data, we believe psychiatrists can recoup their initial capital investment in our system by providing a standard course of treatment to approximately 12 patients. We believe psychiatrists can generate approximately $7,500 to $10,000 of revenue per patient for a standard course of treatment, which may provide meaningful incremental income to their practices. We have a diverse customer base of psychiatrists in group psychiatric practices in the United States. No single customer accounted for more than 10% of our revenues for the years ended December 31, 2018 or 2017. Patients are reimbursed by Medicare and the vast majority of commercial payors in the United States for treatment sessions utilizing our NeuroStar Advanced Therapy System.

We market our products in a few select markets outside the United States through independent distributors. International revenues represented 2% and 1% of our total revenues for the years ended December 31, 2018 and 2017, respectively. In October 2017, we entered into an exclusive distribution agreement with Teijin Pharma Limited, or Teijin, for the distribution of our NeuroStar Advanced Therapy Systems and treatment sessions to customers who will treat patients with MDD in Japan. We received regulatory approval for our system in Japan in September 2017, and we plan to continue to work with Teijin to obtain reimbursement for NeuroStar Advanced Therapy in Japan. We expect our international revenues to increase as a percentage of our total revenues as we grow our presence in Japan.

78

Our research and development efforts are focused on the following: hardware and software product developments and enhancements of our NeuroStar Advanced Therapy System and clinical development relating to additional indications, which may include bipolar depression and post-traumatic stress disorder. We outsource the manufacture of components of our NeuroStar Advanced Therapy Systems that are produced to our specifications, and individual components are either shipped directly from our third-party contract manufacturers to our customers or consolidated into pallets at our Malvern, Pennsylvania facility prior to shipment. Final installation of these systems occurs at the customer site.

Our total revenues increased by $12.3 million, or 31%, from $40.4 million for the year ended December 31, 2017 to $52.8 million for the year ended December 31, 2018. For the year ended December 31, 2018, our U.S. revenues were $51.5 million, compared to $39.9 million for the year ended December 31, 2017, which represented an increase of 29% period over period. We expect to continue to incur losses for the next several years as we expand our commercial organization to support our planned sales growth and while continuing to invest in our pipeline indications. As of December 31, 2018, we had an accumulated deficit of $221.0 million.

On July 2, 2018, we closed our initial public offering, or IPO, in which we issued and sold 6,325,000 shares of our common stock, which included shares sold pursuant to an option granted to the underwriters to purchase additional shares, at a public offering price of $17.00 per share. We received net proceeds $96.5 million after deducting underwriting discounts, commissions and other offering expenses paid by us. Our common stock is listed on the Nasdaq Global Market under the trading symbol “STIM.” Our primary sources of capital to date have been from our IPO, private placements of our convertible preferred securities, borrowings under our credit facilities and revenues from sales of our products.

Components of Our Results of Operations

Revenues

To date, we have generated revenues primarily from the capital portion of our business and related sales and rentals of the NeuroStar Advanced Therapy System and the recurring revenues from our sale of treatment sessions in the United States.

NeuroStar Advanced Therapy System Revenues.    NeuroStar Advanced Therapy System revenues consist primarily of sales or rentals of a capital component, including upgrades to the equipment attributable to the initial sale of the system. NeuroStar Advanced Therapy Systems can be purchased outright or on a rent-to-own basis by certain customers. We had an installed base of 907 and 752 active NeuroStar Advanced Therapy Systems as of December 31, 2018 and 2017, respectively.  

Treatment Session Revenues.    Treatment session revenues primarily include sales of NeuroStar Treatment Sessions and SenStar treatment links. The NeuroStar Treatment Sessions are access codes that are delivered electronically in the United States. The SenStar treatment links are disposable units containing single-use access codes that are sold and used outside the United States. Access codes are purchased separately by our customers, primarily on an as-needed basis, and are required by the NeuroStar Advanced Therapy System in order to deliver treatment sessions.

Other Revenues.    Other revenues are derived primarily from service and repair and extended warranty contracts with our existing customers.

We refer you to the section titled “—Critical Accounting Policies and Use of Estimates—Revenue Recognition” appearing elsewhere in this Annual Report on Form 10-K for additional information regarding how we account for revenues.

Sales in the United States represented 98% and 99% of our total revenues in 2018 and 2017, respectively and have been generated by our direct sales force. Outside the United States, our sales are made through local third-party distributors. International revenues were 2% for the year ended December 31, 2018, compared with 1% for the year ended December 31, 2017. In 2017, we terminated our relationship with our Japanese distributor in anticipation of entering into a new distribution agreement with Teijin, which significantly impacted our international sales for the

79

year ended December 31, 2017. We expect that both our United States and international revenues will increase in the near term as we continue to expand the installed base of NeuroStar Advanced Therapy Systems and increase the related patient utilization in the United States, as well as grow our presence in Japan. We expect our revenues to be positively impacted to the extent our direct sales force is successful in increasing the rate of adoption and utilization of treatment with TMS Therapy as an alternative to other MDD treatments.

Cost of Revenues and Gross Margin

Cost of revenues primarily consists of the costs of components and products purchased from our third-party contract manufacturers of our NeuroStar Advanced Therapy Systems as well as the cost of treatment packs for individual treatment sessions. We use third-party contract manufacturing partners to produce the components for and assemble the completed NeuroStar Advanced Therapy Systems. Cost of revenues also includes costs related to personnel, royalties, warranty, shipping, and our operations and field service departments. We expect our cost of revenues to increase in absolute dollars as and to the extent our revenues grow.

Our gross profit is calculated by subtracting our cost of revenues from our revenues. We calculate our gross margin as our gross profit divided by our revenues. Our gross margin has been and will continue to be affected by a variety of factors, primarily product sales mix, pricing and third-party contract manufacturing costs. Our gross margins on revenues from sales of NeuroStar Advanced Therapy Systems are lower than our gross margins on revenues from sales of treatment sessions and, as a result, the sales mix between NeuroStar Advanced Therapy Systems and treatment sessions can affect the gross margin in any reporting period.

Sales and Marketing Expenses

Sales and marketing expenses consist of market research and commercial activities related to the sale of our NeuroStar Advanced Therapy Systems and treatment sessions and salaries and related benefits, sales commissions and share-based compensation for employees focused on these efforts. Other significant sales and marketing costs include conferences and trade shows, promotional and marketing activities, including direct and online marketing, practice support programs, television and radio media campaigns, travel and training expenses.

We anticipate a significant increase in headcount in our commercial organization and in expenses in executing on our growth initiatives as we continue to expand our business in the United States and internationally. As a result, we expect our sales and marketing expenses to continue to increase in absolute dollars.

General and Administrative Expenses

General and administrative expenses consist primarily of personnel expenses, including salaries and related benefits, share-based compensation and travel expenses, for employees in executive, finance, information technology, legal and human resource functions. General and administrative expenses also include the cost of insurance, outside legal fees, accounting and other consulting services, audit fees from our independent registered public accounting firm, board of directors’ fees and other administrative costs, such as corporate facility costs, including rent, utilities, depreciation and maintenance not otherwise included in cost of revenues.

We anticipate that our general and administrative expenses will increase in absolute dollars because of an expanded infrastructure and an increased headcount. We anticipate higher corporate infrastructure costs including, but not limited to, accounting, legal, human resources, consulting and investor relations fees, listing fees on the Nasdaq Global Market, costs associated with Securities and Exchange Commission, or SEC, reporting and compliance, as well as increased director and officer insurance premiums, as a result of becoming a public company.

Research and Development Expenses

Research and development expenses consist primarily of personnel expenses, including salaries and related benefits and share-based compensation for employees in clinical development, product development, regulatory and quality assurance functions, as well as expenses associated with outsourced professional scientific development services and costs of investigative sites and consultants that conduct our preclinical and clinical development programs. We typically use our employee, consultant and infrastructure resources across our research and development programs.

80

We plan to incur research and development expenses for the near future as we expect to continue our development of TMS Therapy for the treatment of additional patient populations and new indications, which may include bipolar depression, post-traumatic stress disorder and potential other clinical indications yet to be determined, as well as for various hardware and software development projects. As a result, we expect our research and development expenses to continue to increase in absolute dollars.

Interest Expense

Interest expense consists of cash interest payable under our credit facility and non-cash interest attributable to the accrual of final payment fees and the amortization of deferred financing costs related to our indebtedness.

Other (Income) Expense, Net

Other (income) expense, net consists primarily of the revaluation related to our outstanding convertible preferred stock warrants, which were accounted for as a liability as of June 30, 2018 and marked-to-market at each reporting period, as well as gains and losses on the disposal of fixed assets and interest income earned on our money market account balances. Upon the closing of our IPO on July 2, 2018, all of our outstanding convertible preferred stock warrants converted into warrants to acquire an aggregate of 0.1 million shares of our common stock, resulting in the reclassification of the convertible preferred stock warrant liability into additional paid-in capital.

Results of Operations

Comparison of the Years ended December 31, 2018 and 2017

81

Revenues

Total revenues increased by $12.3 million, or 31%, from $40.4 million for the year ended December 31, 2017 to $52.8 million for the year ended December 31, 2018. Revenues in the United States increased by $11.6 million from 2017 to 2018 due to higher unit sales of both NeuroStar Advanced Therapy Systems and treatment sessions. During the fourth quarter of 2017, we entered into an exclusive distribution agreement with Teijin, which we believe will allow us to increase our revenues in Japan once we obtain reimbursement in that country.

Revenues in the United States increased by $11.6 million, or 29%, from $39.9 million for the year ended December 31, 2017 to $51.5 million for the year ended December 31, 2018. NeuroStar Advanced Therapy System revenues in the United States grew by $4.5 million, or 44%, in the year ended December 31, 2018 compared to the year ended December 31, 2017. The increase in U.S. NeuroStar revenue was primarily driven by higher capital revenue growth of 59% due to higher unit sales, partially offset by a 1% decrease in average selling prices, lower upgrade, rent-to-own, and other related revenue. NeuroStar Advanced Therapy System revenues represented 28% and 25% of U.S. revenues for 2018 and 2017, respectively. We believe the growth in NeuroStar Advanced Therapy System revenues between these two periods was the result of the efforts of our expanded commercial organization and increased marketing efforts. As of December 31, 2018, we had an installed base of 907 active systems in the United States, compared to 752 as of December 31, 2017.

Treatment sessions revenues in the United States represented 69% and 71% of total revenues in the United States for the years ended December 31, 2018 and 2017, respectively, and increased by 24% from $28.4 million for the year end December 31, 2017 to $35.3 million for the year ended December 31, 2018. The increase in United States treatment session revenues was primarily the result of an approximate 25% increase in the number of treatment sessions sold, partially offset by a 5% decline in average selling price due to pre-determined volume pricing discounts within our existing customer base which are triggered when those customers surpass certain high volume thresholds, plus an increase in other treatment session revenue.

Cost of Revenues and Gross Margin

Cost of revenues increased by $2.8 million, or 29%, from $9.6 million for the year ended December 31, 2017 to $12.4 million for the year ended December 31, 2018. The increase was primarily due to increased NeuroStar Advanced Therapy System sales. Gross margin was 76.4% for the year ended December 31, 2018 compared to 76.2% for the year ended December 31, 2017. The gross margin was higher due to increased leverage on our service and operation costs, which were partially offset by the higher mix of NeuroStar Advanced Therapy System revenues in 2018 in relation to treatment session revenue and the reduction in average selling prices of our treatment sessions.

Sales and Marketing Expenses

Sales and marketing expenses increased by $10.4 million, or 37%, from $27.9 million for the year ended December 31, 2017 to $38.3 million for the year ended December 31, 2018. The increase was primarily due to increased personnel costs as a result of our sales and marketing expansion activities, as well as higher marketing expenses and sales commission costs, consistent with our growth in revenues. During 2018, we added 15 new sales territories and undertook several marketing projects to support our expansion plans, including increasing our presence at trade shows, expanding our media campaigns and enhancing our practice support program to include patient starter kits.

82

General and Administrative Expenses

General and administrative expenses increased by $5.1 million, or 59%, from $8.6 million for the year ended December 31, 2017 to $13.7 million for the year ended December 31, 2018. The increase was primarily due to an increase in personnel and legal, accounting and other professional services expenses required to support the growth of our business and ready the infrastructure for public company reporting.

Research and Development Expenses

Research and development expenses increased $0.3 million, or 4%, from $7.9 million for the year ended December 31, 2017 to $8.2 million for the year ended December 31, 2018. The increase was primarily due to expenses relating to the launch of the next generation of our NeuroStar Advanced Therapy System and TrakStar practice management system, which were partially offset by declines in spending relating to our adolescent study.

Interest Expense

Interest expense increased $0.9 million, or 31%, from $2.8 million for the year ended December 31, 2017 to $3.7 million for the year ended December 31, 2018, primarily as a result of higher cash interest expenses related to the increase in principal borrowings under our current credit facility and higher non-cash interest expenses accrued in connection with final payment fees due to the lender under the agreement.

Other (Income) Expense, Net

Other expense (income), net decreased by $0.9 million from ($0.3) million for year December 31, 2017 to $0.6 million for the year ended December 31, 2018. The fair value remeasurement of the liability related to our outstanding convertible preferred stock warrants decreased by $1.7 million during the year ended December 31, 2018, which was based on the closing stock price on June 29, 2018, following the pricing of our IPO on June 27, 2018.  Upon closing of our IPO on July 2, 2018, all of our outstanding convertible preferred stock warrants converted into common stock warrants, resulting in the reclassification of our convertible preferred stock warrant liability into additional paid-in-capital.  This decrease was partially offset by a $0.8 million of increase in interest income earned on the proceeds received from the IPO.  Other expense (income), net for 2018 includes a one-time $0.1 million non-utilization fee related to the Company’s election to not draw down the Term C loan, primarily as a result of the funds received from the IPO.

Comparison of the Years ended December 31, 2017 and 2016

83

Revenues

Total revenues increased by $6.2 million, or 18%, from $34.2 million for the year ended December 31, 2016 to $40.4 million for the year ended December 31, 2017. Revenues in the United States increased by $8.3 million from 2016 to 2017 due to higher unit sales of both NeuroStar Advanced Therapy Systems and treatment sessions. International revenues declined by $2.1 million primarily due to the transition of our Japanese distributor during the fourth quarter of 2016. During the fourth quarter of 2017, we entered into an exclusive distribution agreement with Teijin, which we believe will allow us to increase our revenues in Japan once we obtain reimbursement in that country.

Revenues in the United States increased by $8.3 million, or 26%, from $31.6 million for the year ended December 31, 2016 to $39.9 million for the year ended December 31, 2017. NeuroStar Advanced Therapy System revenues in the United States grew by $4.4 million from 2016 to 2017, or 78%, based on 64% higher unit volume and 14% higher average selling prices. NeuroStar Advanced Therapy System revenues represented 18% and 25% of U.S. revenues for 2016 and 2017, respectively. We believe the growth in NeuroStar Advanced Therapy System revenues between these two periods was the result of the efforts of our expanded sales and customer support team to place additional systems.

Treatment sessions revenues in the United States increased by $3.8 million from 2016 to 2017, primarily due to an increase in the installed base of NeuroStar Advanced Therapy Systems. Treatment session revenues represented 78% and 71% of total revenues in the United States for the year ended December 31, 2016 and 2017, respectively. The increase in treatment session revenues in the United States was primarily the result of a 24% increase in the number of treatment sessions performed. This was offset by a 9% decline in average selling price due to certain volume pricing discounts within our existing customer base.

Cost of Revenues and Gross Margin

Cost of revenues increased by $3.0 million, or 45%, from $6.6 million for the year ended December 31, 2016 to $9.6 million for the year ended December 31, 2017. The increase was primarily due to increased NeuroStar Advanced Therapy System sales becoming a larger portion of the sales mix. Gross margin was 76% for the year ended December 31, 2017 compared to 81% for the year ended December 31, 2016. The decrease in gross margin was primarily due to the higher mix of NeuroStar Advanced Therapy System revenues in 2017 in relation to treatment sessions revenues and the reduction in the average selling price of our treatment sessions.

84

Sales and Marketing Expenses

Sales and marketing expenses increased by $6.1 million, or 28%, from $21.8 million for the year ended December 31, 2016 to $27.9 million for the year ended December 31, 2017. The increase was primarily due to increased personnel costs as a result of our sales and marketing expansion activities, as well as higher marketing expenses and sales commission costs, consistent with our growth in revenues. During 2017, we added 15 new sales territories and undertook several marketing projects to support our expansion plans, including increasing our presence at trade shows, expanding our media campaigns and enhancing our practice support program to include patient starter kits.

General and Administrative Expenses

General and administrative expenses increased by $1.7 million, or 24%, from $6.9 million for the year ended December 31, 2016 to $8.6 million for the year ended December 31, 2017. The increase was primarily due to an increase in personnel and legal, accounting and other professional services expenses required to support the growth of our business and ready the infrastructure for public company reporting.

Research and Development Expenses

Research and development expenses decreased $0.3 million, or 3%, from $8.2 million for the year ended December 31, 2016 to $7.9 million for the year ended December 31, 2017. The decrease was primarily due to declines in spending relating to our adolescent study, which were partially offset by expenses relating to the launch of the next generation of our NeuroStar Advanced Therapy System and TrakStar practice management system.

Interest Expense

Interest expense increased $1.0 million, or 53%, from $1.8 million for the year ended December 31, 2016 to $2.8 million for the year ended December 31, 2017, primarily as a result of higher cash interest expenses related to the increase in principal borrowings under our current credit facility and higher non-cash interest expenses accrued in connection with final payment fees due to the lender under the agreement.

Other (Income) Expense, Net

The fair value remeasurement of the liability related to our outstanding convertible preferred stock warrants decreased by $0.3 million during the year ended December 31, 2017 as a result of the change in the fair value of our Series E and Series F convertible preferred stock during 2017.

Liquidity and Capital Resources

Overview

On July 2, 2018, we closed our IPO, in which we issued and sold 6,325,000 shares of our common stock, which included shares sold pursuant to an option granted to the underwriters to purchase additional shares, at a public offering price of $17.00 per share. We received net proceeds of $96.5 million after deducting underwriting discounts, commissions and other offering expenses paid by us.

As of December 31, 2018, we had cash and cash equivalents of $104.6 million and an accumulated deficit of $221.0 million, compared to cash and cash equivalents of $29.1 million and an accumulated deficit of $196.9 million as of December 31, 2017. We incurred negative cash flows from operating activities of $20.6 million and $11.1 million for the years ended December 31, 2018 and 2017, respectively. We have incurred operating losses since our inception, and we anticipate that our operating losses will continue in the near term as we seek to expand our sales and marketing initiatives to support our growth in existing and new markets, invest funds in additional research and development activities and utilize cash for other corporate purposes. Our primary sources of capital to date have been from our IPO, private placements of our convertible preferred securities, borrowings under our credit facilities and sales of our products. As of December 31, 2018, we had $30.0 million of borrowings outstanding under our credit facility, which matures in March 2022.

85

We expect our revenues and expenses to increase in connection with our on-going activities, particularly as we continue to execute on our growth strategy, including expansion of our sales and customer support teams. We also expect to incur additional costs now that we are a public company. Based on our current business plan, we believe that our cash and cash equivalents as of December 31, 2018 and anticipated revenues from sales of our products will be sufficient to meet our anticipated cash requirements for at least the next 24 months after December 31, 2018. However, if these sources are insufficient to satisfy our liquidity requirements, we may seek to sell additional common or preferred equity or debt securities, enter into a new credit facility or another form of third-party funding or seek other debt financing. If we raise additional funds by issuing equity or equity-linked securities, our stockholders would experience dilution and any new equity securities could have rights, preferences and privileges superior to those of holders of our common stock, including the shares of common stock sold in this offering. Debt financing, if available, may involve covenants restricting our operations or our ability to incur additional debt. We cannot be assured that additional equity, equity-linked or debt financing will be available on terms favorable to us or our stockholders, or at all. It is also possible that we may allocate significant amounts of capital towards products or technologies for which market demand is lower than expected and, as a result, abandon such efforts. If we are unable to obtain adequate financing when we require it, or if we obtain financing on terms which are not favorable to us, or if we expend capital on products or technologies that are unsuccessful, our ability to continue to support our business growth and to respond to business challenges could be significantly limited, or we may be required to delay the development, commercialization and marketing of our products.

Our current and future funding requirements will depend on many factors, including:

Cash Flows

The following table sets forth a summary of our cash flows for the years ended December 31, 2018, 2017 and 2016:

86

Net Cash Used in Operating Activities

Net cash used in operating activities for 2018 was $20.6 million, consisting primarily of a net loss of $24.1 million and an increase in net operating assets of $1.6 million, partially offset by non-cash charges of $5.1 million. The increase in net operating assets was primarily due to an increase in accounts receivable and inventory as a result of higher sales volumes. Non-cash charges consisted of depreciation and amortization, non-cash interest expense, share-based compensation, the cost of rental units purchased by customers and the change in the fair value of the liability related to our then-outstanding convertible preferred stock warrants.

Net cash used in operating activities for 2017 was $11.1 million, consisting primarily of a net loss of $16.1 million, offset by an increase in net operating liabilities of $3.2 million and non-cash charges of $1.8 million. The increase in net operating liabilities was primarily due to an increase in deferred revenue representing the initial payment and first milestone payment received in accordance with our Japanese distribution agreement as well as expanding commercial and research activities. Non-cash charges consisted of depreciation and amortization, non-cash interest expense, share-based compensation, the cost of rental units purchased by customers and the change in the fair value of the liability related to our then-outstanding convertible preferred stock warrants.

Net cash used in operating activities for 2016 was $8.5 million, consisting primarily of a net loss of $11.2 million, offset by an increase in net operating liabilities of $1.4 million and non-cash charges of $1.3 million. The increase in net operating liabilities was primarily due to increases in accounts payable and accrued expenses, offset by an increase in inventory primarily due rent-to-own units from one large customer. Non-cash charges consisted of depreciation and amortization, non-cash interest expense, share-based compensation and the change in the fair value of the liability related to our outstanding convertible preferred stock warrants.

Net Cash Used in Investing Activities

Net cash used in investing activities for 2018 was $1.0 million, compared to net cash used in investing activities for 2017 of $0.6 million and $0.3 million for 2016, in each case attributable to purchases of property and equipment and capitalized software costs in 2017 and 2018.

Net Cash Provided by Financing Activities

Net cash provided by financing activities for 2018 was $97.0 million, consisting primarily of $100.0 million of proceeds related to the closing of our IPO on July 2, 2018, partially offset by $3.5 million of payments of costs related to the IPO.

Net cash provided by financing activities for 2017 was $23.8 million, consisting of $14.8 million of net proceeds from the issuance of Series G convertible preferred stock and $10.0 million of borrowings under our current credit facility, offset by payment of $1.0 million of deferred debt issuance costs incurred in connection with our March 2017 amended credit facility.

Net cash provided by financing activities for 2016 was $4.9 million, consisting primarily of $5.0 million of borrowings under our previous credit facility, offset by payment of the related deferred debt issuance costs incurred in connection with a March 2016 amendment.

Indebtedness

Current Credit Facility

In March 2017, we entered into a new loan and security agreement with Oxford Finance LLC, or Oxford, for a credit facility that replaced our previous $25.0 million credit facility with Oxford and which allowed us to borrow up to $35.0 million in three tranches of term loans: a Term A Loan in the amount of $25.0 million, which was drawn down immediately upon closing in March 2017, a Term B Loan in the amount of $5.0 million, which was drawn down in December 2017, and a Term C Loan in the amount of $5.0 million, which became available to us upon the achievement of $45.0 million of trailing twelve month revenues during the second quarter of 2018. Upon achieving the required revenue milestone, we had 60 days to notify Oxford if we elected to borrow the Term C Loan. As a result of completing our IPO on July 2, 2018 and receiving the proceeds therefrom, we elected not to borrow the

87

additional $5.0 million, and it is no longer available to us. Each term loan accrues interest from the date of borrowing through the date of repayment at a floating per annum rate of interest, which resets monthly and is equal to the greater of (a) 8.15% or (b) the 30-day U.S. LIBOR on the last business day of the month plus 7.38%. At the date of each borrowing, we were required to issue to Oxford warrants to purchase our Series F or later series of convertible preferred stock with a seven-year term and in an amount equal to 3.95% of the first $5.0 million of each tranche borrowed. The credit facility matures and all amounts borrowed thereunder are due on March 1, 2022. As of December 31, 2018, we had borrowed and had outstanding an aggregate of $30.0 million of principal under our credit facility.

The Term A Loan featured an interest-only period through March 2019, during which time we were required to make monthly interest payments, after which time we were required to make monthly payments of principal and interest based on a 36-month amortization schedule. However, upon the achievement of $45.0 million of revenues during the fourth quarter of 2018, the interest-only period was extended for an additional 12 months through March 2020, after which time we will be required to make monthly payments of principal and interest based on a 24-month amortization schedule. In connection with the drawdown of the Term A Loan, we issued to Oxford a warrant to purchase shares of its Series F convertible preferred stock. This convertible preferred stock warrant converted into a warrant to purchase 20,303 shares of our common stock at an exercise price of $9.73 per share. The warrant will expire in March 2024.

The Term B Loan featured an interest-only period through March 2019, during which time we were required to make monthly interest payments, after which time we were required to make monthly payments of principal and interest based on a 36-month amortization schedule. However, due to the achievement of $45.0 million of revenues during the fourth quarter of 2018, the interest-only period was extended for an additional 12 months through March 2020, after which time we will be required to make monthly payments of principal and interest based on a 24-month amortization schedule. In connection with the drawdown of the Term B Loan, we issued to Oxford a warrant to purchase shares of its Series F convertible preferred stock. This convertible preferred stock warrant converted into a warrant to purchase 20,303 shares of our common stock at an exercise price of $9.73 per share. The warrant will expire in December 2024.

In addition to principal and interest payments due under the credit facility, we are required to make final payment fees to Oxford due upon the earlier of prepayment or maturity of each tranche, which increased as a result the extension of the interest-only period and are now equal to 8.5% and 7.5% of the principal amounts of the Term A and Term B Loans, respectively. We accrue the estimated final payment fees using the effective interest rate, with a charge to non-cash interest expense, over the term of borrowing for each tranche. As of December 31, 2018, the effective interest rates for the Term A and Term B Loans were 11.87% and 12.14%, respectively. As of December 31, 2017, the effective interest rates for the Term A and Term B Loans were 10.7% and 11.6%, respectively. If the we prepay our term loans prior to their respective scheduled maturities, we will also be required to make prepayment fees to Oxford equal to 3% if prepaid on or before the first anniversary of funding, 2% if prepaid after the first and on or before the second anniversary of funding, or 1% if prepaid after the second anniversary of funding of the principal amounts borrowed.

Our obligations under the credit facility are secured by a first priority security interest in substantially all of our assets, other than our intellectual property. We have agreed not to pledge or otherwise encumber any of our intellectual property. The loan and security agreement related to our credit facility includes a financial maintenance covenant that requires us to achieve at least 75% of our trailing 12-month forecasted revenues, as measured each month in accordance with a forecast that we provided to Oxford upon signing the agreement and future forecasts that we are required to deliver to Oxford each year for the life of the credit facility, as well as customary affirmative and negative covenants. We were in compliance with all of the covenants under our credit facility as of December 31, 2018.

The loan and security agreement related to our credit facility contains events of default, including, without limitation, events of default upon: (i) failure to make payment pursuant to the terms of the agreement; (ii) violation of covenants; (iii) material adverse changes to our business; (iv) attachment or levy on our assets or judicial restraint on our business; (v) insolvency; (vi) significant judgments, orders or decrees for payments by us not covered by insurance; (vii) incorrectness of representations and warranties; (viii) incurrence of subordinated debt; (ix) revocation of governmental approvals necessary for us to conduct our business; and (x) failure by us to maintain a valid and perfected lien on the collateral securing the borrowing.

88

Based on a 24-month amortization of the outstanding principal amounts of the Term A and Term B Loans beginning on April 1, 2020 as discussed above, the following table sets forth by year our required future principal payments (in thousands):

Previous $25.0 Million Credit Facility

Prior to March 2017, we had a $25.0 million credit facility in place with Oxford, which we entered into in February 2014 and which allowed us to borrow up to $25.0 million in three tranches of term loans: a Term A Loan in the amount of $15.0 million, a Term B Loan in the amount of $5.0 million, and a Term C Loan in the amount of $5.0 million, which was never drawn down. Each term loan accrued interest at per annum rates ranging from 8.5% to 8.9%. This facility featured an interest-only period on all tranches through March 2017, and we were also required to issue convertible preferred stock warrants to Oxford at the time of borrowing of each tranche. These convertible preferred stock warrants converted into common stock warrants immediately prior to the closing of our IPO on July 2, 2018,

We accrued final payment fees using the effective interest rate, with a charge to non-cash interest expense, over the term of borrowing and until our entry into our current credit facility in March 2017, at which time we paid the lender $1.0 million in satisfaction of all final payment fee liabilities due under the prior credit facility.

We evaluated whether our current credit facility entered into in March 2017 represented a debt modification or extinguishment in accordance with ASC 470-50, Debt—Modifications and Extinguishments. Upon determining that the change in cash flows between the previous and current credit facilities was not greater than 10%, we accounted for the transaction as a debt modification. As of March 2017, the unamortized balance of deferred financing costs incurred in connection with the $25.0 million credit facility, and certain additional deferred financing costs incurred in connection with entry into our current credit facility, are being amortized to interest expense through March 2022 utilizing the effective interest method.

Cash and Non-Cash Interest Expense

For the year ended December 31, 2018, we recognized interest expense of $3.7 million, of which $2.9 million was cash and $0.8 million was non-cash interest expense related to the amortization of deferred financing costs and accrual of final payment fees. For the year ended December 31, 2017, we recognized interest expense of $2.8 million, of which $2.1 million was cash and $0.7 million was non-cash interest expense related to the amortization of deferred financing costs and accrual of final payment fees.

Off-Balance Sheet Arrangements

We do not maintain any off-balance sheet arrangements, partnerships or other relationships with unconsolidated entities, often referred to as structured finance or special-purpose entities, which are established for the purpose of facilitating off-balance sheet arrangements or other contractually narrow or limited purposes.

89

Commitments and Contractual Obligations

The following table sets forth a summary of our contractual obligations as of December 31, 2018:

Distribution Agreement with Teijin Pharma Limited

In October 2017, we entered into a seven-and-a-half-year distribution agreement with Teijin Pharma Limited, or Teijin, for the exclusive distribution of our NeuroStar Advanced Therapy System to customers who will treat patients with MDD in Japan. Under the distribution agreement, Teijin is generally restricted from selling competing products in Japan. Our distribution agreement provides that we will have primary responsibility for obtaining reimbursement approval for use of NeuroStar Advanced Therapy System for the treatment of MDD in Japan, and Teijin will promote the sales of NeuroStar Advanced Therapy System for treatment of MDD in Japan. We have agreed to provide sales and technical support training to Teijin for our NeuroStar Advanced Therapy Systems.

Teijin is required to purchase minimum dollar values of NeuroStar Advanced Therapy Systems and treatment sessions from us following reimbursement approval by the Japanese Ministry of Health, Labour and Welfare, or JMHLW, for TMS treatment for MDD (or, if such approval requires certified training on the NeuroStar Advanced Therapy System by a third party, then upon the first psychiatrist being issued his or her training certification).

In 2017, under our distribution agreement with Teijin, we received an upfront payment of $0.75 million and a milestone payment of $2.0 million following JMHLW’s approval of marketing the NeuroStar Advanced Therapy System for the treatment of MDD in Japan. These upfront and milestone payments have been deferred and are being recognized as revenue over the seven- and one-half year term of the agreement. Teijin is required to pay us a milestone payment tied to JMHLW issuing reimbursement for use of our products for the treatment of MDD in Japan.

The distribution agreement is scheduled to expire on March 31, 2025, subject to earlier termination if we or Teijin breach the agreement, Teijin fails to maintain distributor-level permits and approvals, Teijin fails to purchase from us specified dollar values of its sales forecasts, reimbursement for treatment of MDD using the NeuroStar Advanced Therapy System is not obtained from JMHLW by specified dates or such reimbursement is below specified minimums, Teijin reasonably believes that it is not commercially reasonable to continue distributing the NeuroStar Advanced Therapy System in Japan or bankruptcy related events occur. The term of the distribution agreement will be automatically extended for two years unless either party gives the other party at least two years’ prior written of notice of non-renewal, except that we cannot decline to renew the agreement if Teijin has purchased 100% of its sales forecasts over the term of the agreement.

Executive Employment Agreements

We are party to an employment agreement and offer letters with certain members of our executive team that provide for severance and other payments following termination of their employment for various reasons. We refer you to “Item 11. Executive Compensation” in this Annual Report on Form 10-K.

The preparation of our financial statements in accordance with accounting principles generally accepted in the United States, or GAAP, and the rules and regulations of the SEC requires us to make estimates and assumptions, based on judgments considered reasonable, which affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. We base our estimates and assumptions on historical experience, known trends and events and various other factors that we believe to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying value of assets and liabilities that are not readily apparent from other sources. Although we believe our estimates and assumptions are reasonable when made, they are based upon information available to us at the time they are made. We evaluate our estimates and assumptions on an ongoing basis and, if necessary, make adjustments. Due to the risks and uncertainties involved in our business and evolving market conditions and given the subjective element of the estimates and assumptions made, actual results may differ from estimated results.

We define our critical accounting policies as those accounting policies that are most important to the portrayal of our financial condition and results of operations and require our most difficult and subjective judgments. While our significant accounting policies are more fully described in “Note 3. Summary of Significant Accounting Policies” in our audited financial statements and related notes thereto appearing elsewhere in this Annual Report on Form 10-K, we believe the following discussion addresses our most critical accounting policies.

Revenue Recognition

Revenue is recognized when title and risk of ownership has been transferred, provided that persuasive evidence of an arrangement exists, the price is fixed and determinable and collectability is reasonably assured. Transfer of title and risk of ownership occurs when the product is shipped or transferred to the customer. We sell to end users in the United States and to third-party distributors outside the United States and do not provide return rights. Sales to distributors outside the United States are made in U.S. dollars.

Our NeuroStar Advanced Therapy System sales in the United States typically have a post-sale training obligation. This obligation is fulfilled after product shipment, and we defer recognizing revenue until training occurs. In accordance with the accounting guidance related to multiple element arrangements, we defer the fair value attributable to the post shipment training and recognize such revenue when the obligation is fulfilled. We base the fair value of the training using stand-alone service rates. Our sales to our third-party distributors outside the United States do not have these post-sale obligations. Our consumable single use and accessory products have no post sale obligations and no return rights. Revenue from the sales of these products are recognized upon delivery. Revenue attributable to the NeuroStar Advanced Therapy Systems purchased on a rent-to-own basis are accounted for as operating leases and revenue is recognized on a straight-line basis over the term of the lease.

In addition, we provide a one to two year warranty for systems sold in the United States. Terms of product warranty differ amongst our third-party distributors outside the United States but are generally two years. We provide for the estimated cost to repair or replace products under any warranty at the time of sale. We also offer our customers in the United States annual service contracts. Revenue from the sale of annual service contracts is recognized on a straight-line basis over the period of the applicable contract. We also earn revenue from customers from services outside of their warranty term or annual service contracts. Such service revenue is recognized as the services are provided.

We had deferred revenue of $1.9 million and $1.6 million at December 31, 2018 and 2017, respectively, primarily related to training, warranty and rent to own units. During the fourth quarter of 2017, we entered into an exclusive Distribution Agreement with Teijin Pharma Limited, which we expect will allow us to increase deliveries to Japan. In connection with the Distribution Agreement, we received an upfront payment as well as the first milestone payment, which are being recognized as revenue over the seven and a half-year term of the agreement. The last milestone payment is due upon achieving reimbursement approval in Japan. At December 31, 2018 and 2017, we had $2.3 million and $2.7 million in deferred revenue, respectively, related to this agreement.

Share-based Compensation

We recognize the grant-date fair value of share-based awards issued as compensation as expense on a straight-line basis over the requisite service period, which is generally the vesting period of the award. Prior to our IPO, the fair value of restricted stock awards is based on a determination by the board of directors of the estimated fair value of the common stock at the date of grant. The fair value of stock options is estimated at the time of grant using the Black-Scholes option pricing model, which requires the use of inputs and assumptions, the most critical of which prior to our IPO is the estimated fair value of our common stock.

We expect the amount of share-based compensation expense recognized for stock options and restricted stock awards and units to increase for future awards in future periods due to the potential increase in both the value of our common stock and the size of our company in terms of headcount.

Valuation of Common Stock

All options to purchase shares of our common stock are granted with an exercise price per share equal to or greater than the estimated fair value per share of our common stock on the date of grant, based on the information known to us on the date of grant. Prior to our IPO, on each grant date, the fair values of the shares of common stock underlying our stock options were estimated on each grant date by our board of directors, based on information known to us at the date of grant. In order to determine the estimated fair value of our common stock, our board of directors considered, among other things, contemporaneous valuations of our preferred and common stock prepared by an unrelated third-party valuation firm in accordance with the guidance provided by the American Institute of Certified Public Accountants 2013 Practice Guide, Valuation of Privately-Held-Company Equity Securities Issued as Compensation. Given the absence of a public trading market for our capital stock, our board of directors exercised reasonable judgment and considered a number of objective and subjective factors to determine the best estimate of the fair value of our preferred and common stock, including:

Since the closing of our IPO, our board of directors has determined the per share fair value of our common stock based on the closing price of our common stock as reported by the Nasdaq Global Market on the date of grant.

JOBS Act Accounting Election

We are an “emerging growth company,” as defined in the Jumpstart Our Business Startups Act of 2012, or JOBS Act, and are eligible to take advantage of certain exemptions from various reporting requirements that are applicable to other public companies that are not emerging growth companies. Section 107 of the JOBS Act provides that an emerging growth company can take advantage of the extended transition period provided in Section 7(a)(2)(B) of the Securities Act of 1933, or Securities Act, for complying with new or revised accounting standards issued subsequent to the enactment of the JOBS Act until such time as those standards apply to private companies. Section 107 of the JOBS Act provides that we can elect to opt out of the extended transition period at any time, which election is irrevocable. We have elected to avail ourselves of this exemption from complying with new or revised accounting standards and, therefore, will not be subject to the same new or revised accounting standards as other public companies that are not emerging growth companies.

92

Subject to certain conditions, as an emerging growth company, we may rely on certain other exemptions and reduced reporting requirements under the JOBS Act, including without limitation (i) providing an auditor’s attestation report on our system of internal controls over financial reporting pursuant to Section 404(b) of the Sarbanes-Oxley Act and (ii) complying with any requirement that may be adopted by the Public Company Accounting Oversight Board regarding mandatory audit firm rotation or a supplement to the auditor’s report providing additional information about the audit and the financial statements, known as the auditor discussion and analysis. We will remain an emerging growth company until the earlier of (a) the last day of the fiscal year in which we have total annual gross revenue of $1.07 billion or more; (b) the last day of the fiscal year following the fifth anniversary of the date of the completion of our IPO; (c) the date on which we have issued more than $1.0 billion in nonconvertible debt during the previous six years; or (d) the date on which we are deemed to be a large accelerated filer under the rules of the SEC.

Recent Accounting Pronouncements

We refer you to “Note 4. Recent Accounting Pronouncements” in our audited financial statements and related notes thereto included elsewhere in this Annual Report on Form 10-K.

Our cash is held on deposit in demand accounts at a large financial institution in amounts in excess of the Federal Deposit Insurance Corporation, or FDIC, insurance coverage limit of $250,000 per depositor, per FDIC-insured bank, per ownership category. We have reviewed the financial statements of this institution and believe it has sufficient assets and liquidity to conduct its operations in the ordinary course of business with little or no credit risk to us.

Financial instruments that potentially subject us to concentrations of credit risk principally consist of cash equivalents and accounts receivable. We limit our credit risk associated with cash equivalents by placing investments in highly-rated money market funds. We limit our credit risk with respect to accounts receivable by performing credit evaluations when deemed necessary, but we do not require collateral to secure amounts owed to us by our customers.

As discussed above in the section of this Annual Report on Form 10-K titled “—Liquidity and Capital Resources—Indebtedness,” our credit facility bears interest at a floating per annum rate of interest, which resets monthly and is equal to the greater of (a) 8.15% or (b) the 30-day U.S. LIBOR on the last business day of the month plus 7.38%. As a result, we are exposed to risks from changes in interest rates. We believe that a one-point increase in interest rates would result in an approximate $0.3 million increase to our interest expense for the year ended December 31, 2018.

Inflationary factors, such as increases in our cost of revenues and operating expenses, may adversely affect our operating results. Although we do not believe inflation has had a material impact on our financial condition, results of operations or cash flows to date, a high rate of inflation in the future may have an adverse effect on our ability to maintain and increase our gross margin or decrease our operating expenses as a percentage of our revenues if our selling prices of our products do not increase as much or more than our costs increase.

We do not currently have any exposure to foreign currency fluctuations and do not engage in any hedging activities as part of our normal course of business.

Evaluation of Disclosure Controls and Procedures

The term “disclosure controls and procedures,” as defined in Rules 13a-15(e) and 15d-15(e) of the Securities Exchange Act of 1934, as amended, or Exchange Act, refers to controls and procedures that are designed to ensure that information required to be disclosed by a company in the reports that it files or submits under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed by a company in the reports that it files or submits under the Exchange Act is accumulated and communicated to the company’s management, including its principal executive officer and principal financial officer, as appropriate to allow timely decisions regarding required disclosure. As required by Rules 13a-15(b) and 15d-15(b) of the Exchange Act, our management, with the participation of our Chief Executive Officer and Chief Financial Officer, evaluated the effectiveness of our disclosure controls and procedures as of the end of the period covered by this Annual Report on Form 10-K. Based on that evaluation, our Chief Executive Officer and our Chief Financial Officer concluded that our disclosure controls and procedures were effective at the reasonable assurance level as of December 31, 2018.

As a result of becoming a public company, we will be required, under Section 404 of the Sarbanes-Oxley Act, to furnish a report by management on, among other things, the effectiveness of our internal control over financial reporting beginning with our Annual Report on Form 10-K for the year ended December 31, 2019. This assessment will need to include disclosure of any material weaknesses identified by our management in our internal control over financial reporting. The SEC defines a material weakness as a deficiency, or combination of deficiencies, in internal control over financial reporting such that there is a reasonable possibility that a material misstatement of a company’s annual or interim financial statements will not be detected or prevented on a timely basis.

Inherent Limitations on Effectiveness of Controls and Procedures

Internal control over financial reporting may not prevent or detect all errors and all fraud. A control system, no matter how well conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the control system are achieved. Further, the design of a control system must be balanced against resource constraints, and therefore the benefits of controls must be considered relative to their costs. Given the inherent limitations in all systems of controls, no evaluation of controls can provide absolute assurance all control issues and instances of fraud, if any, within a company have been detected. These inherent limitations include the realities that judgments in decision making can be faulty and that breakdowns can occur because of a simple error or mistake. Additionally, controls can be circumvented by the individual acts of some persons, by collusion of two or more people or by management override of the controls. The design of any system of controls is also based in part upon certain assumptions about the likelihood of future events, and there can be no assurance that any design will succeed in achieving its stated goals under all potential future conditions; over time, controls may become inadequate because of changes in conditions or the degree of compliance with policies or procedures may deteriorate. Accordingly, given the inherent limitations in a cost-effective system of internal control, financial statement misstatements due to error or fraud may occur and may not be detected. Our disclosure controls and procedures are designed to provide reasonable, not absolute, assurance of achieving their objectives. We conduct periodic evaluations of our systems of controls to enhance, where necessary, our control policies and procedure

Changes in Internal Control over Financial Reporting

During the year ended December 31, 2018, there were no changes in our internal control over financial reporting (as defined in Rule 13a-15(f) of the Exchange Act) which materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

None.

Report of Independent Registered Public Accounting Firm

To the Stockholders and Board of Directors

Neuronetics, Inc.:

Opinion on the Financial Statements

We have audited the accompanying balance sheets of Neuronetics, Inc. (the Company) as of December 31, 2018 and 2017, the related statements of operations, changes in convertible preferred stock and stockholders’ equity (deficit), and cash flows for each of the years in the three-year period ended December 31, 2018, and the related notes (collectively, the financial statements). In our opinion, the financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2018 and 2017, and the results of its operations and its cash flows for each of the years in the three-year period ended December 31, 2018, in conformity with U.S. generally accepted accounting principles.

Basis for Opinion

These financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on these financial statements based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion.
