​

Item 1. Business

​

Unless otherwise indicated or the context otherwise requires, references in this section to “ProSomnus,” “we,” “us,” “our,” and other similar terms refer to ProSomnus Holdings, Inc. and its consolidated subsidiaries prior to the Business Combination and to ProSomnus, Inc. and its consolidated subsidiaries after giving effect to the Business Combination.

​

Overview

​

We are a medical technology company focused on the development, manufacturing and marketing of precision intraoral medical devices, a new non-invasive option for treating and managing patients with mild to moderate obstructive sleep apnea (OSA). Each ProSomnus precision intraoral device is personalized based on the anatomy and treatment plan for each patient. Our patented precision devices are engineered to create unique, consistent and predictable biomechanical advantages that lead to effective, comfortable, economical and patient preferred treatment outcomes for patients with OSA.

​

Each ProSomnus precision intraoral device consists of a series of two splints, one that fits over the upper teeth and another that fits over the lower teeth. Each splint contains lateral prescription posts that precisely and comfortably posture the jaw forward at a prescribed position that opens the airway in the back of the throat to prevent the airway from collapsing at night, minimizing obstruction, snoring and allowing air to flow more easily. The jaw position can be changed by swapping out an upper or lower splint and replacing it with another splint that contains slightly different lateral prescription posts similar to how clear aligner trays are swapped out for orthodontic treatment.

​

Our ProSomnus precision intraoral devices are classified by the U.S. Food and Drug Administration (the FDA) as Class II medical devices for the treatment of snoring and mild to moderate OSA. We received pre-market notification and FDA clearance pursuant to Section 510(k) of the Federal Food, Drug, and Cosmetic Act (FDCA) for our first intraoral device in July 2014 and our devices have been commercially available in the United States since August 2014. To date, over 200,000 ProSomnus precision devices have been prescribed for patients.

​

Sleep apnea is a serious and chronic, respiratory, disease that negatively impacts a patient’s sleep, breathing, health, and quality of life. OSA is the most common form of sleep apnea. OSA is a medical condition characterized by a cessation of breathing when the tongue, soft palate, and other related tissues in the back of the throat collapse and obstruct the upper airway during sleep, temporarily decreasing the oxygen concentration in the blood. During an OSA episode, the diaphragm and chest muscles must work harder to overcome the obstruction and open the airway. These episodes disrupt the sleep cycle, reduce airflow to vital organs, stress the body, and create a negative feedback loop. If untreated, OSA increases the risk of high blood pressure, hypertension, heart failure, stroke, coronary artery disease and other life-threatening diseases. In addition to severe comorbidities, untreated OSA is associated with a reduction in everyday quality-of-life, such as an increase in daytime sleepiness, and an impairment of cognitive function which increases the risk of motor vehicle accidents, poor workplace performance and absenteeism.

​

OSA is a highly prevalent medical disorder. In 2019, Lancet Respiratory Medicine reported that nearly one billion people globally had OSA, including 74 million adults in the United States. Studies report that the prevalence of OSA is increasing, driven by demographic and social health trends. Industry reports and studies estimate that approximately 80% of people with OSA are undiagnosed. Frost and Sullivan estimated that the cost of undiagnosed OSA was $149.6 billion in 2015. In 2010 McKinsey estimated the cost of untreated OSA to be between $65 billion and $165 billion.

​

We believe that the OSA market is ripe for disruption due to the limitations of current therapies. Continuous Positive Airway Pressure (CPAP), the primary incumbent therapy, delivers air pressure into the patient’s airway through a face or nasal mask for the purpose of overcoming obstructions during the night. Many patients find CPAP treatment cumbersome, uncomfortable, claustrophobic, and generally difficult to tolerate, we estimate based on clinical studies that 35%-65% of OSA patients fail to tolerate CPAP.

​

We believe there is a significant population of people with mild to moderate OSA who seek an alternative to CPAP and are eligible for treatment with ProSomnus devices. Industry reports estimate that approximately 7 million people in the United States have stopped using their CPAP machines, representing a significant immediate market opportunity for ProSomnus. We estimate that the failed CPAP opportunity is growing by 700,000 people in the United States each year. We believe that there is a substantial opportunity outside of the United States and that there is a substantial opportunity for ProSomnus device therapy as a frontline alternative to CPAP for patients mild to moderate OSA, particularly with increasing public awareness and medical education.

Table of Contents

Prior to the ProSomnus precision intraoral device, there were few alternatives for OSA patients who refuse or fail CPAP. Historically, treatment alternatives to CPAP have consisted of surgical procedures or legacy dental products. Invasive Surgical procedures, such as hypoglossal nerve stimulation and maxillomandibular advancement, can be irreversible, expensive, and only suitable for a narrow range of patient types such as severe OSA patients within a limited BMI range. Legacy dental products have historically been associated with inconsistent and unreliable performance. We believe that there is both an urgent clinical need and a strong market opportunity for a treatment alternative that is effective, comfortable, non-surgical, convenient, and more economical.

​

Disease management is another important unmet need and opportunity for providers, payors and patients. OSA is a chronic, lifelong, respiratory disease. None of the current therapies are designed to cure OSA. As a result, healthcare providers, patients and payors must manage the disease for the remainder of each patient’s life. Current therapies provide therapeutic data about the function of the device. However, our interviews with leading sleep medicine experts indicate a strong need to efficiently and continuously monitor each patient’s physiologic response to the treatment in an effort to better manage the disease. Physiologic data types include heart rate, blood pressure and blood oxygen levels. Disease management is a significant opportunity for ProSomnus and we are developing a novel product that we believe will fulfill the need and benefit clinicians and their patients.

​

We believe our ProSomnus precision intraoral devices overcome many of the limitations of CPAP and other current treatments of OSA, such as dental products, Hypoglossal Nerve Stimulation and other treatments, by providing the following key benefits:

The results of multiple scientific investigations, which include both company supported and independent studies that evaluated approximately 1,400 patients in total, indicate that ProSomnus devices are effective, efficacious, demonstrate excellent patient compliance rates, reduce sleep apnea events, improve sleep-related quality of life, reduce snoring, help achieve patients’ treatment objectives, and are preferred by patients. In addition, these investigations report high levels of adherence, mitigation of common side effects, strong patient preference for ProSomnus devices over alternatives, and improvements in treatment efficiency. For more information on these studies, see “—Clinical Results and Studies.”

​

The NOTUS3 clinical trial, a third-party investigation published in the Journal of Clinical Sleep Medicine in March 2022, was designed to predict, and evaluate, the efficacy and outcomes of oral appliance therapy for the treatment of OSA. The study reported that 94% of mild and moderate OSA patients were successfully treated using a ProSomnus precision intraoral device. After a six month follow-up period, 85% reported that they achieved their treatment goal with the ProSomnus device and 97% of patients reported a reduction in snoring with a median improvement of six points on a ten-point scale. The Syracuse, Detroit and Multi-center registries, two papers published by the United States Military, and the NOTUS2 study reported similar results for patients with mild to moderate OSA treated with ProSomnus precision intraoral devices.

​

Two company supported studies, “Efficacy and Effectiveness of the ProSomnus® [IA] Sleep Device for the Treatment of Obstructive Sleep Apnea: EFFECTS Study” (sample size: 28 patients) published in Cureus (June 2, 2021) and “Evaluation of a new oral appliance with objective compliance recording capability: a feasibility study” (sample size: 8 patients) published in Journal of Dental Sleep Medicine (2018;5(2)), reported compliance rates of 93.6% and 87.9%; and mean nightly use of 7.2 and 7.4 hours using ProSomnus devices, making ProSomnus devices the only commercially available OSA treatment to objectively record nightly use that meets the American Academy of Sleep Medicine (AASM) and American Academy of Dental Sleep Medicine (AADSM) recommendations for nightly sleep. The 7.2 hours of mean nightly use is approximately 61% better than what is reported in the literature for CPAP.

​

Regarding the mitigation of side effects, an independent study, “Assessment of potential tooth movement and bite changes with a hard acrylic sleep appliance: A 2-year clinical study” (sample size: 18 patients) published in Journal of Dental Sleep Medicine (2019;6(2)) found no statistically or clinically significant changes to tooth position, bite or lower anterior teeth position during the 2.3 year mean test period; and an independent study “Comparative assessment of changes in pharyngeal airway space in cases of obstructive sleep apnea with a customized mandibular repositioning appliance — a clinical study” (sample size: 10 patients) published in Sleep Science (2021 Jan-Mar), found that patients treated with ProSomnus devices reported increase in airway space, improvement in sleepiness and less daytime discomfort, a significant improvement in apnea hypopnea sleep apnea index, oxygen desaturation index, respiratory disturbance index, heart rate, snoring and mean oxygen saturation of arterial blood as compared to baselines, and no significant change in dental occlusion.

​

ProSomnus therapy is a covered benefit for more than 200M beneficiaries of private medical insurance, Medicare, and a growing number of public health insurance programs offered in many countries around the world. In the United States an estimated 70% of treatments are paid for by private insurances, 25% are covered by Medicare and the remaining 5% are paid out-of-pocket by the patient.

​

Typically, the managing physician screens the at-risk person and orders a sleep test. The majority of sleep tests are now conducted at home, expanding access to care. If the test confirms OSA, the managing physician prescribes a treatment modality. If ProSomnus therapy is prescribed, the patient is referred to a therapy provider trained in oral appliance therapy. The oral appliance therapy provider administers the therapy and refers the patient back to the managing physician for follow up.

​

Oral appliance therapy providers are typically reimbursed by private medical insurance in the range of approximately $2,000 to $3,500 per patient for intraoral appliance therapy and by Medicare in the range of approximately $1,250 to $1,800 per patient for intraoral appliance therapy. The average amount varies by insurance provider and Medicare jurisdiction. At these reimbursement levels, we believe that intraoral appliance therapy offers therapy providers an attractive ratio of revenue per chair time in comparison to other procedures.

​

We market and sell our precision intraoral devices to physicians and therapy providers in the United States and in select countries around the world through a direct sales force. We currently have direct sales representatives in the United States and in Europe. Our direct sales force focuses their education, promotional and sales efforts on physicians and therapy providers who have developed a specialty in sleep medicine.Therapy providers are typically dentists, ENTs, nurse practioners, and physcinan assistants who have undergone training in sleep medicine and oral appliance therapy.

​

We generated revenue of $19.4 million, with a gross margin of 52.9% and a net loss of $7.1 million, for the year ended December 31, 2022, compared to revenue of $14.1 million, with a gross margin of 51.9% and a net loss of $6.0 million, for the year ended December 31, 2021. Accumulated deficit incurred from October 2016, after separating from MicroDental Laboratories, to December 31, 2022 was $45.2 million. Including the accumulated deficit incurred by MicroDental Laboratories prior to the sale of that entity in October 2016, accumulated deficit as of December 31, 2022 was $210.8 million.

About Obstructive Sleep Apnea (OSA)

​

OSA is a medical condition characterized by a cessation of breathing, when the tongue, soft palate and other related tissues in the back of the throat collapse and obstruct the upper airway during sleep, temporarily decreasing the oxygen concentration in the blood. During an OSA episode, the diaphragm and chest muscles must work harder to overcome the obstruction and open the airway. These episodes disrupt the sleep cycle, reduce airflow to vital organs, stress the body, and create a negative feedback loop. The lack of airflow can last anywhere from ten seconds to more than a minute, and in severe cases may occur 30 or more times during an hour of sleep. The reduction in blood oxygen triggers an arousal that transiently wakens the patient and opens the airway, leading to a temporary restoration of normal breathing. This cycle occurs throughout the night, decreasing the overall quality of a patient’s sleep, negatively affecting a patient’s breathing, health and significantly reducing their quality of life.

​

The following diagram depicts a typical OSA event in which the base of the tongue falls back and restricts airflow.

​

Table of Contents

​

The severity of OSA is measured by the frequency of apnea or hypopnea events per hour. Apneas are a complete restriction of the airway and hypopneas are a greater than 50% restriction in the airway, both of which are accompanied by a significant decrease in the oxygen levels in the blood. The total number of apneas and hypopneas per hour of sleep is referred to as the Apnea-Hypopnea Index, or AHI. The severity of OSA is based on the following AHI ranges:

​

​

​

​

​

Symptoms and Diagnosis of Obstructive Sleep Apnea

​

Patients struggling with OSA typically have signs and symptoms but are unaware of their condition. Patients who are obese, male or of advanced age are at higher risk for OSA. A common first indicator is that a patient is a heavy snorer. Beyond snoring, a patient may also experience lack of energy, headaches, depression, memory or concentration problems, excessive daytime sleepiness, drowsy driving, nighttime gasping and dry mouth.

​

The impact of heavy snoring creates unrest for both the patient and his or her bed partner. The bed partner’s inability to sleep without interruption often drives the patient to obtain medical advice, usually from their frontline healthcare provider, which is typically a primary care physician or a dentist. If the provider believes the patient may suffer from OSA, they will refer the patient to a sleep medicine physician for diagnosis. The sleep physician will then typically order a sleep study, or polysomnogram, to determine a definitive diagnosis of OSA. This type of sleep study often requires the patient to stay overnight at the sleep center, attached to a variety of monitors and sensors that measure the patient’s airflow, sleep quality, blood oxygen levels and breathing patterns. More recently, physicians have begun prescribing home sleep tests, or HSTs, in lieu of in-office polysomnograms, to help diagnose OSA. We expect that as the use of HSTs, which are more convenient for patients than in-office polysomnograms, continues to increase, the number of patients diagnosed with OSA will also increase.

Comorbidities Associated with OSA and Economic Costs if Untreated

​

Repetitive cessation of breathing during sleep can have a substantial negative impact on affected patients and their quality of life. Published research shows a strong correlation between OSA and negative health outcomes, including:

​

​

​

​

An 18-year longitudinal follow-up study at the University of Wisconsin demonstrated the risk of these co-morbidities. The 1,522-person Wisconsin Sleep Cohort sample reported significantly reduced survival rates for individuals with untreated OSA.

​

Untreated OSA is also associated with significantly higher healthcare costs. A report by Frost and Sullivan, commissioned by the American Academy of Sleep Medicine, estimates that the cost of untreated OSA was $149.6 billion in 2015, and that the people with untreated OSA are three times more expensive than people with OSA who are treated. In 2010 McKinsey estimated the cost of untreated OSA to be between $65 billion and $165 billion.

​

Prevalence of Sleep Apnea

​

We believe the prevalence of OSA is large and growing. In 2019, The Lancet Respiratory Medicine estimated that nearly 1 billion adults aged 30 – 69 years have mild to severe OSA globally and approximately 74 million adults aged 30 – 69 years have mild to severe OSA in North America, suggesting that the condition is both underdiagnosed and under-recognized. There are two types of sleep apnea: OSA and Central Sleep Apnea, or CSA. OSA is the most common form of sleep apnea and is caused by a physical obstruction of the airway. By contrast, CSA is far less common and is caused by the brain’s inability to send appropriate signals to the muscles in the chest that control breathing. Our ProSomnus precision intraoral medical devices are designed to treat patients with OSA.

​

Current Treatments for OSA and their Limitations

​

There are several treatment options for OSA. CPAP is the most commonly prescribed therapy for patients with OSA. The other common approaches for treating patients with OSA are surgical procedures (including implantable devices) and intraoral appliance therapy devices.

​

CPAP

​

CPAP is delivered through a face or nasal mask that connects through a hose to a bedside air pump. The pump forces air through the hose to the mask and down the patient’s throat, keeping the airway open and allowing the patient to breathe. In order for treatment with CPAP to be most effective, the mask must form an airtight seal on the patient’s face or nose and the mask must be worn every night.

​

​

CPAP is the incumbent therapy and has demonstrated improvements in AHI during sleep tests. Patient-reported sleep quality and reductions in daytime sleepiness associated with the number of hours of use. Many patients who use a CPAP device report symptom relief, increased energy levels, and an improvement in mental sharpness during the day.

​

Despite the efficacious treatment CPAP offers, overall nightly therapeutic effectiveness is limited by low patient compliance. Based on published literature, we estimate that only approximately 35% to 65% of patients prescribed a CPAP device are compliant with the therapy. Commonly cited reasons patients fail to use their CPAP device on a regular basis include mask discomfort, mask leakage, pressure intolerance, skin irritation, nasal congestion, nasal drying, nosebleeds, claustrophobia, social concerns, and lack of intimacy. Low patient compliance persists despite the development of various CPAP device improvements and auxiliary technologies designed to improve patient comfort and treatment through a variety of methods, including coaching, patient education and remote monitoring.

Legacy Dental Product Therapy Devices

​

Legacy dental product therapy is an alternative treatment to CPAP that is preferable for many patients due to comfort, convenience and the lack of side effects in comparison with CPAP. However, legacy dental product therapy devices suffer from imprecision, which can limit the efficacy and predictability of the treatment. When dental product manufacturers create their devices, their process capability is typically plus or minus several millimeters, which can lead to the finished oral appliance deviating significantly from the patient’s anatomy, prescription, and treatment plan, thereby compromising efficacy, comfort and overall performance. A difference of several millimeters is thought to be clinically significant. The mean airway width for a patient with OSA is approximately 10 millimeters. Several studies establish the dose dependent relationship between oral appliance jaw repositioning and treatment efficacy, further indicating the importance of precision when repositioning the mandible.

​

Surgical Procedures

​

In cases of OSA where CPAP has failed or patients have discontinued treatment, surgery may be an alternate therapy. Three of the primary surgical procedures for treating OSA are uvulopalatopharyngoplasty, or UPPP, maxillomandibular advancement, or MMA, and hypoglossal nerve stimulation, or HNS. In a UPPP procedure, the surgeon remodels the structure of the airway by removing excess tissue that is believed to be responsible for obstructing the airway. This can include the uvula, part of the soft palate or roof of the mouth, excess throat tissue, tonsils, adenoids and part of the tongue. Although the most common surgical procedure for OSA, UPPP has only a 33% to 50% success rate, and its efficacy fades with time. In an MMA procedure, a surgeon reconstructs the lower jaw by breaking the jaw and inserting spacers to reposition it forward by approximately 10 millimeters. This surgery is thought to be more effective than UPPP, but it is considered an extreme procedure due to the dramatic change in physical appearance it can cause. Both of these are invasive inpatient procedures that irreversibly alter the patient’s anatomy and require extended and painful recovery periods. The typical recovery period for a UPPP procedure is three weeks, and for an MMA procedure is several months. While these procedures may be effective in reducing OSA, the success rates vary widely.

​

Other surgical options for the treatment of OSA include hypoglossal nerve stimulation. HNS is a surgically implanted system that includes a pulse generator implanted in the patient’s body, an implanted stimulation lead that delivers the signal from the pulse generator to the hypoglossal nerve, an implanted sensing lead that measures breathing patterns, and a remote control. Currently HNS has a very narrow indication for use, limited to severe OSA patients who have failed CPAP. In addition to being invasive, HNS is expensive.

​

We believe there is a significant population in the United States and globally with OSA who are eligible for ProSomnus precision intraoral devices and are unable to use or get consistent benefit from CPAP. We believe that there is both an urgent clinical need and a strong market opportunity for an effective, non- invasive, convenient and economical alternative to CPAP and surgical procedures to treat OSA.

​

ProSomnus Precision Intraoral Medical Devices — Our Solution for Treatment of OSA

​

​

We believe that ProSomnus precision intraoral medical devices are well positioned to address the limitations of competing OSA therapies by offering a more effective, convenient and economical therapy for patients, providers and payors. Utilizing a proprietary precision manufacturing platform, ProSomnus intraoral devices are more precise, comfortable, customizable and easier to use than other current treatments. We believe that ProSomnus precision intraoral devices offer the opportunity for better effectiveness, adherence, outcomes and fewer side effects than CPAP.

Table of Contents

​

ProSomnus precision intraoral medical devices are personalized for each patient based on their unique anatomy, treatment plan and prescription, similar to eyeglass lenses or clear aligners for orthodontic treatment. Each ProSomnus intraoral device consists of a series of two splints, one that fits over the upper teeth and another that fits over the lower teeth. Each splint contains a lateral prescription post that precisely and gently postures the jaw at the prescribed position and opens the airway in the back of the throat to prevent the airway from collapsing at night, minimizing obstructions, snoring and allowing breathing to flow more easily. Jaw position can be changed by swapping out an upper or lower splint and replacing it with another splint that contains a slightly different lateral prescription post position, like  how clear aligner trays are swapped out for orthodontic treatment.

​

We believe that precision prescription transfer enables ProSomnus devices to perform better than other treatment options, including traditional oral appliances. A study supported by ProSomnus was designed to evaluate the prescription transfer precision of several leading traditional oral appliances and ProSomnus devices. One millimeter of variance to the prescribed jaw position is generally recognized as a clinically significant level of variance. The study reported that traditional oral appliances exhibited approximately 3.7 millimeters variance to the prescribed jaw position. The implication is that approximately 29% of traditional oral appliances satisfy the prescription transfer specification, with 71% falling outside of the prescription transfer specification limit. The study also reported that ProSomnus devices demonstrated approximately 0.3 millimeters of variance to the prescribed jaw position, well within the one-millimeter threshold. The implication is that 99% of ProSomnus devices fall within the prescription transfer specification. We believe that our precision prescription transfer advantage, enabled by our unique digital manufacturing platform, translates into performance benefits for the provider and patient.

​

ProSomnus intraoral devices are designed to make it easy for the patient to follow a normal bedtime routine and adhere to therapy, every night. For example, patients can talk, read, watch TV and drink water while wearing their ProSomnus intraoral device. Patients can go to the bathroom without removing it. They can travel with it. ProSomnus intraoral devices are easy to keep clean, do not require power, water or the bulky equipment and accessories associated with CPAP, and are easy to replace if lost.

​

Patient Treatment Process

​

Most potential patients learn they may be a possible candidate for OSA therapy from their bedpartners, physician examinations, word of mouth recommendation, search engines and medical websites, education and advertising campaigns, and/or dentist examinations. Some useful predictive information can be obtained from self-reported questionnaires given to the patient in advance of a formal evaluation, and this procedure may simplify the clinical assessment of patients. Medical organizations are beginning to include screening for OSA in routine physical examinations or during other medical evaluations, particularly for patients who are symptomatic.

​

We believe that dentists are uniquely positioned to identify patients who are at risk of OSA and refer patients to physicians for diagnosis. During routine dental examinations, dentists can identify certain anatomical risk factors such as a small upper airway. They can ask a few simple screening questions or provide questionnaires to further examine a patient’s likelihood of having OSA. Data indicates that most patients visit their dentists more frequently than they visit their primary care physician, placing dentists in an important position for OSA screening. The AASM asserts that dentists have the access and expertise to screen for OSA and refer patients for diagnosis, and the American Dental Association has recommended that all dentists perform OSA screening. The combination of these facts places dentists in a unique position for the screening of OSA and will likely increase awareness and diagnosis rates over time.

​

If a primary care physician or dentist believes that a patient may have OSA, he or she will generally refer the patient to a sleep physician, who will typically order either a home sleep apnea test or a full polysomnography test, which provides detailed information on sleep state, respiratory behavior and gas exchange abnormalities, in addition to a range of other variables including body position, heart rate and rhythm, and muscle tone and activity. The sleep physician then makes a diagnosis based on the results of the sleep test.

​

If a patient is diagnosed with sleep apnea and is a candidate for intraoral appliance therapy, the physician will prescribe intraoral appliance therapy as the treatment modality and make a referral to a sleep dentist. The sleep dentist then prescribes a particular intraoral appliance therapy device, such as one of our ProSomnus precision intraoral devices. The dentist typically takes an impression of the patient’s teeth using an intraoral scanner and sends the data and a prescription to us. The ProSomnus precision intraoral device is then designed based on the provided digitized patient information and the dentist’s prescription. A milling robot fabricates the device from medical grade (U.S. Pharmacopeia (USP) Class VI compliant) polymer, using a series of milling tools that are controlled by milling strategy software. The device is then labeled and polished. The finished device is then packaged and sent to the dentist for delivery to the patient.

​

The manufacture of a ProSomnus intraoral device typically takes seven production days, in comparison with several weeks for legacy dental product. Upon receipt of the customized ProSomnus intraoral device by the dentist, the patient will visit the dentist for the fitting of the device. The patient may then take a new post- treatment home sleep apnea test or a polysomnography test to determine the efficacy of the ProSomnus intraoral device on the patient. Though dental sleep providers report that many patients are treated without

need for adjustment, dentists easily adjust the treatment by instructing the patient to swap upper or lower splints that contain different prescription settings.

​

Market Opportunity

​

The North America obstructive sleep apnea device market was estimated to be $3.47 billion dollars in 2021 (Market Data Forecast). The market is forecasted to expand at a compound annual growth rate of 8.1% between 2022 and 2027 (Market Data Forecast). Research estimates that there are 74 million adults in North America with Obstructive Sleep Apnea, of which 18 million have been diagnosed. The underlying drivers of growth are the obesity and aging population trends. Studies indicate that the incidence and severity of OSA is correlated with obesity and age. We believe there is a significant population of people in North America with mild to moderate OSA who seek an alternative to CPAP and are eligible for treatment with ProSomnus devices. Industry reports estimate that approximately 7 million people with OSA of all severities in the United States have stopped using CPAP, representing a $4 billion dollar immediate opportunity for ProSomnus. We estimate that the failed CPAP opportunity is growing by 700,000 people in the United States each year. We believe that there is a substantial opportunity outside of the United States. We also believe there is a substantial opportunity for ProSomnus device therapy as a frontline alternative to CPAP for patients mild to moderate OSA, particularly with increasing public awareness and medical education. And there is an opportunity for ProSomnus’s next generation devices to enable more efficient disease management via remote patient monitoring technologies.

​

Clinical Results and Studies

​

A significant and growing body of published clinical evidence, including approximately 1,400 unique patient data points from multiple studies evaluated across several independent and company supported clinical investigations, supports the efficacy, compliance, safety, patient preference and symptom alleviation of ProSomnus therapy for patients with OSA.

​

​

Efficacy

​

Based on our own market intelligence surveys and third-party surveys, efficacy is one of the primary considerations for a managing physician when selecting a treatment modality.

​

The table below highlights the key findings from 5 studies comprising 326 unique patients that evaluate the efficacy of treating patients with mild to moderate OSA utilizing ProSomnus precision intraoral devices. ProSomnus precision devices demonstrated a weighted average success rate of 93% in these studies that reported data for patients with mild and moderate OSA.

​

​

Table of Contents

Seven additional studies, including 936 unique patients, report on the efficacy associated with treating OSA patients of all severity levels with ProSomnus precision intraoral devices. Three independent studies published by the US Army, US Army Public Health Center Report on Obstructive Sleep Apnea Surveillance in 2022, Knowles in Military Medicine 2021, Kang in Military Medicine 2022, evaluated 360, 288, and 24 patients, respectively. The US Army Public Health Center Report, 2022, found that patients treated indicated improvements in sleep and quality of life. Knowles, 2021, reported that 88.1% of patients with all severities of OSA were successfully treated, and that patients treated with precision intraoral devices represented significant cost savings over alternative treatments such as CPAP. Kang, 2022, concluded that 87.5% of patients with OSA of all severities were successfully treated. Rohatgi in JDSM 2019, reported that 211 consecutively treated patients with ProSomnus precision devices experienced statistically and clinically significant improvements in OSA events and sleepiness even with practicing a conservative approach to jaw repositioning. Hu et al in General Dentistry 2020, reported a 62% mean reduction of OSA events without titrating the prescription for 26 patients diagnosed with OSA. Carlton in Dental Sleep Practice 2016, and Hu in Dental Sleep Practice 2015, reported 75% and 71% improvement in OSA events for 20 and 7 patients, respectively.

​

Compliance

​

Two company supported studies, published in peer-reviewed medical journals involving thirty-six total patients, evaluated patient compliance with ProSomnus precision intraoral devices. Both studies utilized ProSomnus devices fitted with thermo-sensors to objectively record nightly use. The table below highlights the key findings from these studies.

​

​

These studies demonstrate a high level of compliance at 93.6% and 87.9%, and mean nightly usage of 7.2 and 7.4 hours per night, with ProSomnus precision devices. For context, based on published literature we estimate the compliance rates for CPAP devices to be between 35% and 65%, and mean nightly use of approximately 4.5 hours. We believe that ProSomnus precision intraoral devices are the only devices that have demonstrated, in multiple studies using objectively recorded data, mean nightly use that meets or exceeds the AASM and AADSM recommended 7 hours of mean nightly usage.

​

Side Effects

​

Two studies, both independent, evaluated patients treated with ProSomnus precision intraoral devices for tooth position and bite changes for a minimum duration of 2 years. Tooth position and bite changes are dental oriented side effects commonly associated with CPAP and legacy dental products. The table below provides the key highlights from these studies.

​

​

In both studies, ProSomnus precision intraoral devices did not demonstrate the types of unwanted tooth movements and unwanted bite changes that have been reported in the literature with CPAP and legacy dental products. None of the tooth movements and bite changes were calculated as being statistically significant.

​

Patient Preference

​

The American Academy of Sleep Medicine notes that it is important for healthcare providers to consider patient preference when selecting a treatment modality, “…patient preference for OAs (oral appliances) versus CPAP should be considered by the treating sleep physician before therapy is prescribed.” Elliott et al conducted a 31-patient preference study with the scientific abstract published in the journal, Sleep, in 2021. Their study intercepted 31 patients in treatment with CPAP or traditional oral appliances and converted them to ProSomnus precision devices. 100% of patients stated that they preferred the ProSomnus precision devices to their prior device.

Snoring

​

ProSomnus therapy is indicated by the FDA for the treatment of snoring. At six-month follow-up, 96.7% of participants in the independent NOTUS3 study reported a median improvement in snoring of 6 levels on a 10-point scale. See table below. The EFFECTS study utilized the Snore Severity Score (“SSS”), and reported a statistically significant improvement in snoring when the patients were treated with ProSomnus precision devices.

​

​

Sales and Marketing

​

We sell our ProSomnus intraoral devices through a direct sales force that primarily targets sleep dentists, sleep physicians, primary care providers, otolarygologists (ENTs), and other integrated healthcare service providers. We have an established provider network across the United States. ProSomnus devices are authorized by the United States Department of Defense and US Army for the treatment of service men and woman who have OSA. We are currently initiating the marketing and sales of our ProSomnus intraoral devices in several European countries and intend to further expand our marketing and direct sales into international markets.

​

The AASM practice guidelines specify dentists with OSA training as the primary channel for delivering and managing intraoral appliance therapy for patients with OSA. Dentists can further specialize in sleep medicine by obtaining a credential of Diplomate from the American Board of Dental Sleep Medicine (ABDSM).

​

ABDSM diplomates are sleep trained dentists who have demonstrated competency in sleep medicine and who must actively engage in continuing education to maintain their credential. We estimate that approximately 6,000 dentists in the United States practice dental sleep medicine, a key call point for our sales and marketing efforts.

​

We currently have twelve direct sales representatives in the North America and four in Europe, for a total of sixteen direct sales representatives. We project increasing our count of direct sales representative to eighty over the forecast horizon. Increasing the count of direct sales representatives is one of the main growth drivers for our revenue projections. We seek to recruit sales representatives with strong direct sales backgrounds, experience in the dental or respiratory medicine markets, and core knowledge of medical device coding, medical affairs, and reimbursement. We believe there is a robust talent pool of sales professionals with relevant skills and experience. Our expectations for sales representative productivity are largely based on the historical performance of our sales representatives, management experience, and data available for comparable medical device companies with direct sales representatives. We anticipate normal variability in the performance of our sales representatives relative to our productivity expectations. Variability is largely driven by the performance of each representative, but also other factors such as the timing of when each representative is hired within a period.

​

Our company has put into place several programs to increase the probability of each representative achieving productivity expectations. These programs, which are continuously updated, include:

​

​

We also utilize direct communication channels to inform and educate patients about ProSomnus intraoral devices and to enable them to connect with active qualified sleep dentists that offer our intraoral devices. Our primary methods of patient, physician and dentist outreach are search engine marketing, social media advertising, medical and dental journal advertising, trade shows and clinical education and in-office engagement of dentists and physicians. The objective of this outreach is to raise awareness of OSA and make it easy for at risk people to access care by using our website to read educational materials and find a list of providers in their area.

​

We utilize a five-stage prescription decision process to organize our sales and marketing efforts for the purpose of optimizing demand for our devices. This process is largely based upon a tried-and-true understanding of how healthcare providers select medical devices. The five stages to our process are: 1. Problem/opportunity awareness; 2. Information search; 3. Evaluation of options; 4. Prescription decision; and 5. Post-prescription activity.

​

The objective of the first stage, Problem/opportunity awareness, is to make the healthcare provider aware that our devices might help them to address problems or opportunities for their patients with OSA. This is largely accomplished through clinical education programming, ranging from sponsoring a conference such as the AASM or AADSM annual meetings to advertising in relevant medical journals. Healthcare providers that respond to our awareness programming are considered leads.

​

The objective of the second stage of our process, Information search, is to make it easy for healthcare providers, particularly the leads from our Problem/opportunity stage, to find information about our devices. We accomplish this by providing copies of relevant journal articles, references of healthcare providers who are already prescribing our devices, or sponsoring speakers at conferences.

​

Evaluation of options is the third stage of our marketing and sales process. The objective for this stage is to help healthcare providers make rational and conscious comparisons between our devices and competitive alternatives. This stage of the process largely involves a sales representative providing a healthcare provider with white papers, studies, journal articles, scientific abstracts, specifications and other technical details about our devices.

​

The fourth stage of our process is Prescription decision. The objective of the Prescription decision stage is to facilitate a trial order from the healthcare provider. Programming for this stage focuses on preparing the healthcare provider to prescribe a ProSomnus device in the form of pricing agreements, in-servicing, providing prescription pads, instructions for use, and other documents necessary to prescribe a device.

​

Post-prescription activity is the fifth stage of our prescription decision marketing and sales process. This stage involves a sales representative conducting post-prescription surveillance regarding any previously prescribed devices.

​

Third Party Reimbursement

​

We typically sell our ProSomnus intraoral devices to sleep dentists. These customers in turn bill various third-party payors, such as commercial payors, Medicare and the various social health plans of various countries around the world, for the cost of the device. The list price for each product is based upon an analysis of competitive prices, capacity dynamics, marginal manufacturing costs, incremental value created to the customer and our business strategy. We offer a quarterly volume based discount program, as well as incentives for new customers.

​

In the United States third-party payors require physicians and dentists to identify the service for which they are seeking reimbursement by using Current Procedural Terminology (CPT) codes, which are created and maintained by the American Medical Association (AMA). Our ProSomnus precision intraoral medical devices can be billed in and out of network to most commercial payors under the E0486 or K1027 CPT codes. The devices under CPT codes E0486 and K1027 are reimbursable by many major commercial medical payors following a medical diagnosis of OSA. Dentists and other healthcare providers are typically reimbursed by private medical insurance in the range of approximately $2,000 to $3,500 per patient for intraoral appliance therapy, although medical insurance is never a guarantee of payment, and patient deductibles and policy limitations may vary. Preauthorization may be required for reimbursement and preauthorization requirements may vary based on the payor policies and patient’s insurance coverage. Although many patients pay for treatment out of pocket on a fee-for-service basis, the availability of health insurance coverage is an important consideration for many patients who desire using our ProSomnus intraoral medical devices. Commercial medical insurance policies have different reimbursement policies which may affect availability of reimbursement.

​

Table of Contents

Dentists typically remain out of network with commercial health insurance payors, but this depends on the individual practice and the commercial payor guidelines in each state. As out of network providers, dentists can set their own fees and balance bill the patient for the cost of care not covered by the patient’s health insurance. The AMA provides fee ranges for all billable CPT codes. A dentist must set their own fees for the CPT codes billed in their office that are within their scope of practice.

​

ProSomnus intraoral medical devices under the E0486 and K1027 HCPCS codes are reimbursable by Medicare or Medicaid. Physician reimbursement under Medicare generally is based on a defined fee schedule, the Physician Fee Schedule, through which payment amounts are determined by the relative values of the professional service rendered. Dentists and other healthcare providers are typically reimbursed by Medicare in the range of approximately $1,250 to $1,800 per patient for intraoral appliance therapy. The average amount varies by Medicare jurisdiction.

​

Manufacturing and Supply

​

We have developed a proprietary digital precision manufacturing platform that enables us to produce intraoral medical devices with greater speed, better precision and increased personalization parameters at lower cost points than our competitors’ intraoral appliances. After a sleep dentist takes an impression of the patient’s teeth using an intraoral scanner or other device, they send it to us along with a prescription. We then use our proprietary, artificial intelligence-driven software to create a custom design for the intraoral device using the digitized patient information and the dentist’s prescription. Once the design is complete, we use computer-assisted manufacturing and a robotic milling machine to fabricate the device from medical grade (USP Class VI compliant) polymer. The device is then labeled, polished, packaged and sent to the dentist for delivery to the patient.

​

Our quality system is required to be in compliance with the Quality System regulations enforced by the FDA, and similar regulations enforced by other worldwide regulatory authorities. We have a formal, documented quality system by which quality objectives are defined, understood and achieved. Systems, processes and procedures are implemented to ensure high levels of product and service quality. We monitor the effectiveness of the quality system based on internal data and direct customer feedback and strive to continually improve our systems and processes, taking corrective action, as needed.

​

Since the manufacturing process of our products requires substantial and varied technical expertise, we believe that our manufacturing capabilities are important to our success. In order to produce our highly customized, highly precise intraoral medical devices in volume, we have developed a number of proprietary processes and technologies. These technologies include complex software algorithms and solutions, artificial intelligence, and the highest quality medical grade materials. To increase the efficiency of our manufacturing processes, we continue to focus our efforts on software development and the improvement of rate-limiting processes. We continuously upgrade our proprietary, three-dimensional treatment planning software to enhance computer analysis of treatment data and to reduce time spent on manual and judgmental tasks for each case, thereby increasing the efficiency of our technicians. In addition, to improve efficiency and increase the scale of our operations, we continue to invest in the development of automated systems for the fabrication and packaging of our intraoral devices.

​

Research and Development

​

We are committed to investing in world-class technology development, which we believe is critical to achieving our goal of establishing our ProSomnus intraoral devices as the standard method for treating OSA. Our research and development expenses were $3.0 million and $1.9 million for the years ended December 31, 2022 and 2021, respectively.

​

Our research and development activities are directed toward developing the technology innovations that we believe will deliver our next generation of products and platforms. These activities range from accelerating product and clinical innovation to developing manufacturing process improvements to researching future technologies and products. We received FDA clearance for an intraoral device that enables remote patient monitoring services in November 2020. We believe that these services could provide us with an additional recurring revenue stream.

​

Competition

​

Our industry is subject to significant competition and rapid change from the introduction of new products and technologies and other activities of industry participants. We currently compete as a first-line therapy in the OSA treatment market for patients with mild to moderate OSA. We intend to also compete as a first-line therapy for patients with severe OSA if we receive clearance from the FDA to do so. There are several treatment options for patients with OSA depending on the level of severity of the disease, ranging from lifestyle changes to surgery. The goals of therapy are to resolve signs and symptoms of OSA, improve sleep quality, normalize and reduce the AHI, and generally increase blood oxygen saturation levels.

​

We consider our primary competition to be manufacturers and providers of both CPAP and legacy intraoral appliance products. Providers of CPAP devices include ResMed, Philips Respironics and Fisher & Paykel. These companies are focused on CPAP devices,

Table of Contents

with efforts to increase the rate of diagnosis worldwide. To address adherence issues, these companies are focused on home monitoring technologies.

​

Legacy dental products (most of which represent variations on the same mandibular advancement device platform) are typically delivered by licensed dentists and are usually fabricated in a dental laboratory. According to the American Sleep Apnea Association, over 100 different intraoral appliances are FDA cleared for the treatment of snoring and OSA. Manufacturers include SomnoMed, DynaFlex, and Respire.

​

We believe other emerging businesses are in the early stages of developing other intraoral appliance devices which incorporate novel technologies.

​

We may also compete with makers of surgically implanted upper airway stimulation devices for the treatment of OSA, including Inspire Medical (Inspire).

​

Some of our competitors have more financial resources than we do, while others have a more diversified set of products and end markets. Accordingly, such competitors may be able to more quickly respond to innovations, changes in patient demand, and market developments, and to better withstand external economic or market factors.

​

Intellectual Property

​

We rely on a combination of patent, copyright, trademark and trade secret laws and confidentiality agreements to protect our intellectual property rights, including entering into invention assignment agreements with our employees in the ordinary course of their employment. As of March 17, 2023, we have rights to: nine (9) issued U.S. utility patents, which will expire between Dec. 24, 2034, and Oct. 23, 2038, assuming all required fees are paid; one (1) issued U.S. design patent; three (3) pending U.S. patent applications, six (6) issued and active foreign patents and ten (10) pending foreign and WIPO-PCT patent applications.

​

We also rely, in part, upon unpatented trade secrets, know-how and continuing technological innovation, and may in the future rely upon licensing opportunities to develop and maintain our competitive position. We protect our proprietary rights through a variety of methods, including confidentiality and assignment agreements with suppliers, employees, consultants and others who may have access to our proprietary information.

​

There is no active patent litigation involving any of our patents and we have not received any notices of patent infringement. Our industry faces claims of infringement and litigation regarding patent and other intellectual property rights. Patent infringement is an ongoing risk, in part because other companies in our industry could have patent rights that may not be identifiable as we develop our products and services. Litigation may be necessary to enforce our intellectual property rights, and we may have to defend ourselves against infringement claims

​

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 the EEA. Our products are subject to regulation as medical devices under the Federal Food, Drug, and Cosmetic Act, or 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 the EEA governing clinical trials and the commercial sales and distribution of our products. Whether or not we have or are required to obtain FDA clearance or approval for a product, we will be required to obtain authorization before commencing clinical trials and to obtain marketing authorization or approval of our products under the comparable regulatory authorities of countries outside of the United States before we can commence clinical trials or commercialize our products in those countries. The approval 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 pre-market approval (PMA). 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 effectiveness. Class I includes devices with the lowest risk to the

Table of Contents

patient and are those for which safety and effectiveness can be assured by adherence to the FDA’s General Controls for medical devices, which include compliance with the applicable portions of the 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 effectiveness 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. Under the 510(k) process, the manufacturer must submit to the FDA a premarket notification demonstrating that the device is “substantially equivalent” to either a device that was legally marketed (for which the FDA has not required a PMA submission) prior to May 28, 1976, the date upon which the Medical Device Amendments of 1976 were enacted, or another commercially available device that was cleared to through the 510(k) process. The FDA has 90 days from the date of the pre- market equivalence acceptance to authorize or decline commercial distribution of the device. However, similar to the PMA process, clearance may take longer than this three-month window, as the FDA can request additional data. If the FDA resolves that the product is not substantially equivalent to a predicate device, then the device acquires a Class III designation, and a PMA must be approved before the device can be commercialized.

​

Our company markets and manufacturers Class II, FDA-cleared, medical devices. Our MicrO2 medical device has a 510(k) clearance as a Class II medical device with the FDA for the treatment of mild to moderate OSA and snoring. Our CA medical device has a 510(k) clearance as a Class II medical device with the FDA for the treatment of mild to moderate OSA and snoring. Our MicrO2 and CA 510(k) clearances include options for the provider to add Micro-recorders for the purpose of monitoring patient compliance. Our EVO has a 510(k) clearance as a Class II medical device with the FDA for the treatment of mild to moderate OSA and snoring. This device also has a 510(k) clearance as a Class II medical device with the FDA for the treatment of mild to moderate OSA and snoring with Patient Monitoring technology to monitor the performance of the device and the health of the patient.

​

Our FDA 510(k) clearances are summarized in the table below.

​

​

We are currently engaged with the FDA in a process to determine the safety and efficacy of our ProSomnus precision intraoral devices for the treatment of severe OSA, as an additional expanded indication for use. We intend to apply for a 510(k) clearance for this expanded indication upon completion of our clinical study.

​

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. Some pre-amendment devices are unclassified, but are subject to the FDA’s premarket notification and clearance process in order to be commercially distributed. We do not have any Class III devices.

​

PMA Pathway

​

Class III devices require PMA approval before they can be marketed although some pre-amendment Class III devices for which the FDA has not yet required a PMA are cleared through the 510(k) process. The PMA process is more demanding than the 510(k) premarket notification process. In a PMA application, the manufacturer must demonstrate that the device is safe and effective, and the PMA application must be supported by extensive data, including data from preclinical studies and human clinical trials. The PMA must also contain a full description of the device and its components, a full description of the methods, facilities and controls used for manufacturing, and proposed labeling. Following receipt of a PMA application, the FDA determines whether the application is sufficiently complete to permit a substantive review. If the FDA accepts the application for review, it has 180 days under the FDCA to complete its review of a PMA application, although in practice, the FDA’s review often takes significantly longer, and can take up to several years. An advisory panel of experts from outside the FDA may be convened to review and evaluate the application and provide

Table of Contents

recommendations to the FDA as to the approvability of the device. The FDA may or may not accept the panel’s recommendation. In addition, the FDA will generally conduct a preapproval inspection of the applicant or its third-party manufacturers.

​

The FDA will approve the new device for commercial distribution if it determines that the data and information in the PMA application constitute valid scientific evidence and that there is reasonable assurance that the device is safe and effective for its intended use(s). 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 a PMA approval or requirements to conduct additional clinical studies post-approval. The FDA may condition a PMA approval on some form of post-market surveillance when deemed necessary to protect the public health or to provide additional safety and efficacy data for the device in a larger population or for a longer period of use. In such cases, the manufacturer might be required to follow certain patient groups for a number of years and to make periodic reports to the FDA on the clinical status of those patients. Failure to comply with the conditions of approval can result in material adverse enforcement action, including withdrawal of the approval.

​

Certain changes to an approved device, such as changes in manufacturing facilities, methods, or quality control procedures, or changes in the design performance specifications, which affect the safety or effectiveness of the device, require submission of a new PMA application or a PMA supplement. PMA supplements often require submission of the same type of information as a 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. Certain other changes to an approved device require the submission of a new PMA application, such as when the design change causes a different intended use, mode of operation, and technical basis of operation, or when the design change is so significant that a new generation of the device will be developed, and the data that were submitted with the original PMA application are not applicable for the change in demonstrating a reasonable assurance of safety and effectiveness.

​

Clinical Trials

​

Clinical trials are almost always required to support a PMA application and are sometimes required to support a 510(k) submission. All clinical investigations of investigational devices to determine safety and effectiveness must be conducted in accordance with the FDA’s investigational device exemption, or IDE, regulations which govern investigational device labeling, prohibit promotion of the investigational device, and specify an array of recordkeeping, reporting and monitoring responsibilities of study sponsors and study investigators. If the device presents a “significant risk” to human health, as defined by the FDA, the FDA requires the device sponsor to submit an IDE application to the FDA, which must become effective prior to commencing human clinical trials. A significant risk device is one that presents a potential for serious risk to the health, safety or welfare of a patient and either is implanted, used in supporting or sustaining human life, substantially important in diagnosing, curing, mitigating or treating disease or otherwise preventing impairment of human health, or otherwise presents a potential for serious risk to a subject. An IDE application must be supported by appropriate data, such as animal and laboratory test results, showing that it is safe to test the device in humans and that the testing protocol is scientifically sound. The IDE will automatically become effective 30 days after receipt by the FDA unless the FDA notifies us that the investigation may not begin. If the FDA determines that there are deficiencies or other concerns with an IDE for which it requires modification, the FDA may require a response on such deficiencies or permit a clinical trial to proceed under a conditional approval.

​

In addition, the study must be approved by, and conducted under the oversight of, an Institutional Review Board, or IRB, for each clinical site. The IRB is responsible for the initial and continuing review of the IDE, and may pose additional requirements for the conduct of the study. If an IDE application is approved by the FDA and one or more IRBs, human clinical trials may begin at a specific number of investigational sites with a specific number of patients, as approved by the FDA. If the device presents a non- significant risk to the patient, a sponsor may begin the clinical trial after obtaining approval for the trial by one or more IRBs without separate approval from the FDA, but must still follow abbreviated IDE requirements, such as monitoring the investigation, ensuring that the investigators obtain informed consent, and labeling and record-keeping requirements. Acceptance of an IDE application for review does not guarantee that the FDA will allow the IDE to become effective and, if it does become effective, the FDA may or may not determine that the data derived from the trials support the safety and effectiveness of the device or warrant the continuation of clinical trials. An IDE supplement must be submitted to, and approved by, the FDA before a sponsor or investigator may make a change to the investigational plan that may affect its scientific soundness, study plan or the rights, safety or welfare of human subjects.

​

During a study, the sponsor is required to comply with the applicable FDA requirements, including, for example, trial monitoring, selecting clinical investigators and providing them with the investigational plan, ensuring IRB review, adverse event reporting, record keeping and prohibitions on the promotion of investigational devices or on making safety or effectiveness claims for them. The clinical investigators in the clinical study are also subject to FDA regulations and must obtain patient informed consent, rigorously follow the investigational plan and study protocol, control the disposition of the investigational device, and comply with all reporting and recordkeeping requirements. Additionally, after a trial begins, we, the FDA or the IRB could suspend or terminate a clinical trial at any time for various reasons, including a belief that the risks to study subjects outweigh the anticipated benefits.

Post-market Regulation

​

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

​

​

​

​

​

​

A person or entity does not have to have actual knowledge of this statute or specific intent to violate it to have committed a violation;

​

​

​

​

​

​

​

​

We may be subject to similar foreign laws that may include applicable post-marketing requirements such as safety surveillance. 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, our facilities, records and manufacturing processes are subject to periodic scheduled or unscheduled inspections by the FDA. Our failure to maintain compliance with the QSR or other

applicable regulatory 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 or a public warning letter that could harm both our reputation and revenue. Any potential consequences of off-label use of our intraoral devices are the responsibility of the treating dentist; however, we may face consequences related to such off-label use.

​

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:

Regulation of Medical Devices in the EEA

​

There is currently no premarket government review of medical devices in the EEA (which is comprised of the 27 Member States of the European Union (“EU”) plus Norway, Liechtenstein, and Iceland). However, all medical devices placed on the market in the EEA must meet the relevant essential requirements laid down in Annex I of Directive 93/42/EEC concerning medical devices (the “Medical Devices Directive” or “MMD”). There is also a directive specifically addressing Active Implantable Medical Devices (Directive 90/385/EEC) (the “Active Implantable Medical Devices Directive” or “AIMDD”). The most fundamental essential requirement is that a medical device must be designed and manufactured in such a way that it will not compromise the clinical condition or safety of patients, or the safety and health of users and others. In addition, the device must achieve the performances intended by the manufacturer and be designed, manufactured, and packaged in a suitable manner. The European Commission has adopted various standards applicable to medical devices available in the EU. These include standards governing common requirements, such as sterilization and safety of medical electrical equipment and product standards for certain types of medical devices. There are also harmonized standards relating to design and manufacture. While not mandatory, compliance with these standards is viewed as the easiest way to satisfy the essential requirements as a practical matter. Compliance with a standard developed to implement an essential requirement also creates a rebuttable presumption that the device satisfies that essential requirement.

​

To demonstrate compliance with the essential requirements laid down in Annex I to the MDD, medical device manufacturers must undergo a conformity assessment procedure, which varies according to the type of medical device and its classification. Conformity assessment procedures require an assessment of available clinical evidence, literature data for the product, and post-market experience in respect of similar products already marketed. Except for low-risk medical devices (Class I non-sterile, non-measuring devices), where the manufacturer can self-declare the conformity of its products with the essential requirements (except for any parts which relate to sterility or metrology), a conformity assessment procedure requires the intervention of a notified body. Notified bodies are organizations designated by an EU country to assess the conformity of certain products before being placed on the market. These bodies carry out tasks related to conformity assessment procedures set out in the legislation and typically audit and examine a product’s technical dossiers and the manufacturers’ quality system. If satisfied that the relevant product conforms to the relevant essential requirements, the notified body issues a certificate of conformity, which the manufacturer uses as a basis for its own declaration of conformity. The manufacturer may then apply the CE Mark to the device, which allows the device to be placed on the market throughout the EEA. Once the product has been placed on the market in the EEA, the manufacturer must comply with requirements for reporting incidents and field safety corrective actions associated with the medical device.

​

In order to demonstrate safety and efficacy for their medical devices, manufacturers must conduct clinical investigations in accordance with the requirements of Annex X to the MDD, Annex 7 to the AIMDD, and applicable European and International Organization for Standardization (“ISO”) standards, as implemented or adopted in the EEA Member States. Clinical investigations for

Table of Contents

medical devices usually require the approval of an ethics review board and approval by or notification to the national regulatory authorities. Both regulators and ethics committees also require the submission of serious adverse event reports during a study and may request a copy of the final study report.

​

On May 25, 2017, the new Medical Devices Regulation (2017/745 or “MDR”) entered into force, which repeals and replaces the EU MDD and AIMDD. Unlike directives, which must be implemented into the national laws of the EEA Member States, regulations are directly applicable, i.e., without the need for adoption of EEA Member State laws implementing them, in all EEA Member States and are intended to eliminate current differences in the regulation of medical devices among EEA Member States. The MDR, among other things, is intended to establish a uniform, transparent, predictable, and sustainable regulatory framework across the EEA for medical devices and ensure a high level of safety and health while supporting innovation. The MDR was due to become applicable in May 2021, but in light of COVID-19, on April 23, 2020, the European Parliament and the Council of the EU adopted a proposal to extend the transitional period of the MDR by one year, i.e. until May 26, 2021. However, devices lawfully placed on the market pursuant to the MDD or AIMDD prior to May 26, 2021 may generally continue to be made available on the market or put into service until May 26, 2025. Once applicable, the new regulations will among other things:

​

Following the end of the “Brexit” Transition Period, from January 1, 2021 onwards, the Medicines and Healthcare Products Regulatory Agency (“MHRA”) will be responsible for the UK medical device market. The new regulations will require medical devices to be registered with the agency (but manufacturers will be given a grace period of four to 12 months to comply with the new registration process). Manufacturers based outside the UK will need to appoint a UK Responsible Person to register devices with the MHRA in line with the grace periods. By July 1, 2023, in the UK (England, Scotland, and Wales), all medical devices will require a UKCA (UK Conformity Assessed) mark but CE marks issued by EU notified bodies will remain valid until this period. However, UKCA marking alone will not be recognized in the EU. The rules for placing medical devices on the Northern Ireland market will differ from those in the UK.

​

Similarly, we are subject to regulations and product registration requirements in many foreign countries in which we may sell our products, including in the areas of:

The time required to obtain clearance required by foreign countries may be longer or shorter than that required for FDA clearance, and requirements for licensing a product in a foreign country may differ significantly from FDA requirements.

​

Federal, State, and Foreign Fraud and Abuse and Physician Payment Transparency Laws

​

In addition to FDA restrictions on marketing and promotion of drugs and devices, other federal and state laws restrict our business practices. These laws include, without limitation, foreign, federal, and state anti- kickback and false claims laws, as well as transparency laws regarding payments or other items of value provided to healthcare providers.

​

The federal Anti-Kickback Statute prohibits, among other things, knowingly and willfully offering, paying, soliciting or receiving any remuneration (including any kickback, bribe or rebate), directly or indirectly, overtly or covertly, in cash or in kind to induce or in return for purchasing, leasing, ordering or arranging for or recommending the purchase, lease or order of any good, facility, item or service reimbursable, in whole or in part, under Medicare, Medicaid or other federal healthcare programs. The term “remuneration” has been broadly interpreted to include anything of value, including stock, stock options, and the compensation derived through ownership interests.

​

Although there are a number of statutory exceptions and regulatory safe harbors protecting some common activities from prosecution, the exceptions and safe harbors are drawn narrowly. Practices that involve remuneration that may be alleged to be intended to induce prescribing, purchases or recommendations may be subject to scrutiny if they do not qualify for an exception or safe harbor. Failure to meet all of the requirements of a particular applicable statutory exception or regulatory safe harbor does not make the conduct per se illegal under the federal Anti-Kickback Statute. Instead, the legality of the arrangement will be evaluated on a case-by-case basis based on a cumulative review of all its facts and circumstances. Conduct and business arrangements that do not fully satisfy one of these safe harbor provisions may result in increased scrutiny by government enforcement authorities. Several courts have interpreted the statute’s intent requirement to mean that if any one purpose of an arrangement involving remuneration is to induce referrals of federal healthcare covered business, the federal Anti-Kickback Statute has been violated. In addition, a person or entity does not need to have actual knowledge of the statute or specific intent to violate it in order to have committed a violation.

​

The majority of states also have anti-kickback laws which establish similar prohibitions and in some cases may apply more broadly to items or services covered by any third-party payor, including commercial insurers and self-pay patients.

​

The federal civil False Claims Act prohibits, among other things, any person or entity from knowingly presenting, or causing to be presented, a false or fraudulent claim for payment or approval to the federal government or knowingly making, using or causing to be made or used a false record or statement material to a false or fraudulent claim to the federal government. A claim includes “any request or demand” for money or property presented to the U.S. government. The federal civil False Claims Act also applies to false submissions that cause the government to be paid less than the amount to which it is entitled, such as a rebate. Intent to deceive is not required to establish liability under the civil federal civil False Claims Act.

​

Moreover, a claim including items or services resulting from a violation of the federal Anti-Kickback Statute constitutes a false or fraudulent claim for purposes of the federal civil False Claims Act.

​

In addition, private parties may initiate “qui tam” whistleblower lawsuits against any person or entity under the federal civil False Claims Act in the name of the government and share in the proceeds of the lawsuit. The government may further prosecute conduct constituting a false claim under the federal criminal False Claims Act. The criminal False Claims Act prohibits the making or presenting

Table of Contents

of a claim to the government knowing such claim to be false, fictitious or fraudulent and, unlike the federal civil False Claims Act, requires proof of intent to submit a false claim.

​

The Civil Monetary Penalty Law imposes penalties against any person or entity that, among other things, is determined to have presented or caused to be presented a claim to a federal healthcare program that the person knows or should know is for an item or service that was not provided as claimed or is false or fraudulent, or offering or transferring remuneration to a federal healthcare beneficiary that a person knows or should know is likely to influence the beneficiary’s decision to order or receive items or services reimbursable by the government from a particular provider or supplier.

​

The Health Insurance Portability and Accountability Act of 1996 (“HIPAA”) also created additional federal criminal statutes that prohibit among other actions, knowingly and willfully executing, or attempting to execute, a scheme to defraud any healthcare benefit program, including private third-party payors, knowingly and willfully embezzling or stealing from a healthcare benefit program, willfully obstructing a criminal investigation of a healthcare offense, and knowingly and willfully falsifying, concealing or covering up a material fact or making any materially false, fictitious or fraudulent statement in connection with the delivery of or payment for healthcare benefits, items or services. Similar to the federal Anti-Kickback Statute, a person or entity does not need to have actual knowledge of the statute or specific intent to violate it in order to have committed a violation.

​

Many foreign countries have similar laws relating to healthcare fraud and abuse. Foreign laws and regulations may vary greatly from country to country. For example, the advertising and promotion of our products is subject to EU directives concerning misleading and comparative advertising and unfair commercial practices, as well as specific EEA Member State legislation governing the advertising and promotion of medical devices. These laws, which vary between jurisdictions (thus making compliance more complex), may limit or restrict the advertising and promotion of our products to the general public and may impose limitations on our promotional activities with healthcare professionals. Many EEA Member States have adopted specific anti-gift statutes that further limit commercial practices for our products, in particular vis- à-vis healthcare professionals and organizations. Also, many U.S. states have similar fraud and abuse statutes or regulations that may be broader in scope and may apply regardless of payor, in addition to items and services reimbursed under Medicaid and other state programs.

​

Additionally, there has been a recent trend of increased foreign, federal, and state regulation of payments and transfers of value provided to healthcare professionals or entities. The federal Physician Payments Sunshine Act imposes annual reporting requirements on certain drug, biologics, medical supplies and device manufacturers for which payment is available under Medicare, Medicaid or CHIP for payments and other transfers of value provided by them, directly or indirectly, to physicians, as defined by statute, certain other healthcare providers beginning in 2022, and teaching hospitals, as well as ownership and investment interests held by physicians and their immediate family members. Manufacturers must submit reports by the 90th day of each calendar year. Many EU Member States have adopted national “Sunshine Acts” which impose similar reporting and transparency requirements (often on an annual basis) on certain drug, biologics and medical device manufacturers. Certain foreign countries and U.S. states also mandate implementation of commercial compliance programs, impose restrictions on device manufacturer marketing practices and require tracking and reporting of gifts, compensation, and other remuneration to healthcare professionals and entities.

​

Violation of any of the federal and state healthcare laws described above or any other governmental regulations that apply to device manufacturers may result in significant penalties, including the imposition of significant civil, criminal and administrative penalties, damages, disgorgement, monetary fines, imprisonment, possible exclusion from participation in Medicare, Medicaid and other federal healthcare programs, contractual damages, reputational harm, diminished profits and future earnings, additional reporting requirements and/or oversight if the entity becomes subject to a corporate integrity agreement or similar agreement to resolve allegations of non-compliance with these laws, and curtailment of operations.

​

Data Privacy and Security Laws

​

We are also subject to various federal, state, and foreign laws that protect personal information including certain patient health information, such as the EU General Data Protection Regulation (“GDPR”) and the California Consumer Privacy Act (“CCPA”) which became effective as of January 2020, and restrict the use and disclosure of patient health information by healthcare providers, such as HIPAA, as amended by HITECH, in the United States.

​

HIPAA established uniform standards governing the conduct of certain electronic healthcare transactions and requires certain entities, called covered entities, to comply with standards that include the privacy and security of protected health information (“PHI”). HIPAA also requires business associates, such as independent contractors or agents of covered entities that have access to PHI in connection with providing a service to or on behalf of a covered entity, of covered entities to enter into business associate agreements with the covered entity and to safeguard the covered entity’s PHI against improper use and disclosure.

​

The HIPAA privacy regulations cover the use and disclosure of PHI by covered entities as well as business associates, which are defined to include subcontractors that create, receive, maintain, or transmit PHI on behalf of a business associate. They also set forth

Table of Contents

certain rights that an individual has with respect to his or her PHI maintained by a covered entity, including the right to access or amend certain records containing PHI, or to request restrictions on the use or disclosure of PHI. The security regulations establish requirements for safeguarding the confidentiality, integrity, and availability of PHI that is electronically transmitted or electronically stored. HITECH, among other things, established certain health information security breach notification requirements. A covered entity must notify any individual whose PHI is breached according to the specifications set forth in the breach notification rule. The HIPAA privacy and security regulations establish a uniform federal “floor” and do not supersede state laws that are more stringent or provide individuals with greater rights with respect to the privacy or security of, and access to, their records containing PHI or insofar as such state laws apply to personal information that is broader in scope than PHI as defined under HIPAA.

​

HIPAA requires the notification of patients, and other compliance actions, in the event of a breach of unsecured PHI. If notification to patients of a breach is required, such notification must be provided without unreasonable delay and in no event later than 60 calendar days after discovery of the breach. In addition, if the PHI of 500 or more individuals is improperly used or disclosed, we would be required to report the improper use or disclosure to the U.S. Department of Health and Human Services (“HHS”) which would post the violation on its website, and to the media. Failure to comply with the HIPAA privacy and security standards can result in significant civil monetary penalties and criminal penalties.

​

HIPAA authorizes state attorneys general to file suit on behalf of their residents for violations. Courts are able to award damages, costs and attorneys’ fees related to violations of HIPAA in such cases. While HIPAA does not create a private right of action allowing individuals to file suit against us in civil court for violations of HIPAA, its standards have been used as the basis for duty of care cases in state civil suits such as those for negligence or recklessness in the misuse or breach of PHI. In addition, HIPAA mandates that the Secretary of HHS conduct periodic compliance audits of HIPAA covered entities, and their business associates for compliance with the HIPAA privacy and security standards. It also tasks HHS with establishing a methodology whereby harmed individuals who were the victims of breaches of unsecured PHI may receive a percentage of the civil monetary penalty paid by the violator.

​

In addition, California enacted the CCPA, effective January 1, 2020, which, among other things, creates new data privacy obligations for covered companies and provides new privacy rights to California residents, including the right to opt out of certain disclosures of their information. The CCPA also creates a private right of action with statutory damages for certain data breaches, thereby potentially increasing risks associated with a data breach. Although the law includes limited exceptions, including for “protected health information” maintained by a covered entity or business associate, it may regulate or impact our processing of personal information depending on the context. Further, the California Privacy Rights Act (“CPRA”), recently passed in California. The CPRA will impose additional data protection obligations on covered businesses, including additional consumer rights processes, limitations on data uses, new audit requirements for higher risk data, and opt-outs for certain uses of sensitive data. It will also create a new California data protection agency authorized to issue substantive regulations and could result in increased privacy and information security enforcement. The majority of the provisions will go into effect on January 1, 2023, and additional compliance investment and potential business process changes may be required.

​

In the EU, the EEA and the United Kingdom we are subject to laws that restrict our collection, control, processing, and other use of personal data (i.e. data relating to an identifiable living individual) including the GDPR and the United Kingdom Data Protection Act 2018 (and any applicable national laws implementing the GDPR). We process personal data in relation to our operations, including clinical investigations. We process data of our employees, contractors, suppliers, distributors, service providers, and our customers, as well as patient or clinical investigation participants, including health and medical information of such participants. We need to ensure compliance with the GDPR (and any applicable national laws implementing the GDPR) in each EU and EEA jurisdiction where we are established or are otherwise subject to the GDPR (i.e., jurisdictions in which we are targeting or monitoring EU and EEA located individuals, or offering goods or services to EU located individuals. We also need to ensure compliance with the Data Protection Act 2018.

​

The GDPR imposes onerous accountability obligations including: maintaining a record of data processing; implementing policies and a privacy governance framework; disclosing to data subjects how their personal data is to be used; limiting retention of personal data; mandatory data breach notification requirements; and high standards for data controllers to demonstrate that they have obtained valid consent for certain data processing activities. In addition, the GDPR permits EU Member State derogations for certain matters and, accordingly, we are also subject to EU national laws relating to the processing of genetic data, biometric data, and health data. We have a robust program that we believe ensures compliance with these obligations. Fines for certain breaches of the GDPR are significant: up to the greater of EUR 20 million or 4% of total global annual turnover. In addition to the foregoing, a breach of the GDPR could result in regulatory investigations, reputational damage, orders to cease/ change our use of data, enforcement notices, as well potential civil claims including class action type litigation where individuals suffer harm.

​

We are also subject to GDPR requirements with respect to cross-border transfers of personal data out of the EU and we need to ensure that such transfers are legitimized by valid transfer solutions and/or derogations under the GDPR (where required), including by entering into the EU Commission approved model contracts for the transfer of personal data to third countries (i.e., the standard contractual clauses). The law is also developing rapidly and, in July 2020, the Court of Justice of the EU limited how organizations

Table of Contents

could lawfully transfer personal data from the EEA to the United States. As such, there is a possibility that the standard contractual clauses may be invalidated as a compliant data transfer mechanism in the near future. In addition, following the end of the Transition Period, the UK has become a “third party” for the purposes of EU-to-UK personal data transfers. The significant implications of this are mitigated by the agreement of a 4-6 month grace period, during which time the EU Commission will consider whether to grant an adequacy decision which would continue to permit unrestricted EU-to-UK personal data transfers following the expiry of the grace period. We have enlisted the help of external advisors to implement a robust GDPR program that we believe achieves and maintains compliance with these obligations, but it is likely it will require us to expend additional capital and other resources for upcoming GDPR changes.

​

We depend on a number of third parties in relation to the operation of our business, a number of which process personal data on our behalf. With each new provider we perform security assessments and detailed due diligence, enter into contractual arrangements which require that they only process personal data according to our instructions, and which require that they have sufficient technical and organizational security measures in place. We have enlisted the help of external advisors to provide assistance in implementing these contractual arrangements with our existing providers. There is no assurance that these contractual measures and our own privacy and security-related safeguards will protect us from the risks associated with the third-party processing, storage, and transmission of such information. Any violation of data or security laws by our third party processors could have a material adverse effect on our business and result in the fines and penalties outlined above.

​

We are also subject to evolving EU privacy laws on cookies and e-marketing. The EU is in the process of replacing the E-Privacy Directive with a new set of rules in the form of a regulation, which will be directly applicable to all EU Member States. The draft E-Privacy Regulation imposes strict opt-in marketing rules with limited exceptions for business-to-business communications, alters rules on third-party cookies, web beacons, and similar technology and significantly increases fining powers to the same levels as the GDPR (i.e. the greater of 20 million Euros or 4% of total global annual revenue for certain breaches). The e-Privacy Regulation is still going through the European legislative process and commentators expect it to be agreed during 2021, after which a two-year transition period will follow before it is in force. We have enlisted the help of external advisors to implement a robust GDPR program that achieves and maintains compliance with these obligations, but it is likely it will require us to expend additional capital and other resources for upcoming GDPR changes.

​

Healthcare Reform

​

The United States and some foreign jurisdictions are considering or have enacted a number of legislative and regulatory proposals to change the healthcare system in ways that could affect our ability to sell our products profitably. Among policy makers and payors in the United States and elsewhere, there is significant interest in promoting changes in healthcare systems with the stated goals of containing healthcare costs, improving quality or expanding access.

​

Current and future legislative proposals to further reform healthcare or reduce healthcare costs may limit coverage of or lower reimbursement for the procedures associated with the use of our products. The cost containment measures that payors and providers are instituting and the effect of any healthcare reform initiative implemented in the future could impact our revenue from the sale of our products.

​

The implementation of the Affordable Care Act in the United States, for example, has changed healthcare financing and delivery by both governmental and private insurers substantially, and affected medical device manufacturers significantly. The Affordable Care Act, among other things, provided incentives to programs that increase the federal government’s comparative effectiveness research, and implemented payment system reforms including a national pilot program on payment bundling to encourage hospitals, physicians, and other providers to improve the coordination, quality, and efficiency of certain healthcare services through bundled payment models. Additionally, the Affordable Care Act expanded eligibility criteria for Medicaid programs and created a new Patient-Centered Outcomes Research Institute to oversee, identify priorities in, and conduct comparative clinical effectiveness research, along with funding for such research.

​

Since its enactment, there have been judicial, executive and Congressional challenges to certain aspects of the Affordable Care Act. By way of example, the Tax Cuts and Jobs Acts was enacted, which, among other things, removes penalties for not complying with the individual mandate to carry health insurance, beginning in 2019. On December 14, 2018, a U.S. District Court Judge in the Northern District of Texas, ruled that the Affordable Care Act’s individual mandate to carry insurance coverage is a critical and inseverable feature of the Affordable Care Act, and therefore, because it was repealed as part of the Tax Cuts and Jobs Act, the remaining provisions of the Affordable Care Act are invalid as well. On December 18, 2019, the U.S. Court of Appeals for the 5th Circuit upheld the District Court’s decision that the individual mandate was unconstitutional but remanded the case back to the District Court to determine whether the remaining provisions of the Affordable Care Act are invalid as well. The U.S. Supreme Court is currently reviewing the case, although it is unclear how the Supreme Court will rule. It is also unclear how other efforts, if any, to challenge, repeal or replace the Affordable Care Act will impact the Act or our business.

​

Table of Contents

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

​

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.

​

Anti-Bribery and Corruption Laws

​

Our U.S. operations are subject to the FCPA. We are required to comply with the FCPA, which generally prohibits covered entities and their intermediaries from engaging in bribery or making other prohibited payments to foreign officials for the purpose of obtaining or retaining business or other benefits. In addition, the FCPA imposes accounting standards and requirements on publicly traded U.S. corporations and their foreign affiliates, which are intended to 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 also are subject to similar anticorruption legislation implemented in Europe through EU Member State laws and under the Organization for Economic Co-operation and Development’s Convention on Combating Bribery of Foreign Public Officials in International Business Transactions.

​

Seasonality

​

Historically, ProSomnus has experienced seasonality in the first and fourth quarters. Revenues have been more robust in the fourth quarter and less robust in the first quarter, and we expect this trend to continue. Seasonality is largely attributable to patients in the United States who are actively managing their out-of-pocket expenses, which may be higher in the beginning of the year when patients are less likely to have met the annual deductibles for their private insurance policies, and lower toward the end of the year when patients are more likely to have met their annual deductibles.

​

Human Capital

​

As of December 31, 2022, we had 125 employees in North America and 4 in Europe. None of our employees is subject to a collective bargaining agreement or represented by a trade or labor union. We consider our relationship with our employees to be good. We believe that our turnover and productivity levels are at acceptable levels.

​

Corporate Information

​

We incorporated under the laws of the State of Delaware in March 2016. Our principal executive offices are located at 5675 Gibraltar Drive, Pleasanton, CA 94588, and our telephone number is (844) 537-5337.

Item 1A. Risk Factors

​

You should carefully consider all of the risks described below, together with the other information contained in this report, including the financial statements, before making a decision to invest in our securities. If any of the following risks occur, our business, financial

Table of Contents

condition or operating results may be materially and adversely affected. In that event, the trading price of our securities could decline, and you could lose all or part of your investment.

​

Risks Related to ProSomnus’s Business and Industry

​

Our business has a limited operating history, which may make it difficult to evaluate the prospects for our future viability and predict our future performance. As such, you cannot rely upon our historical operating performance to make an investment or voting decision regarding ProSomnus.

​

ProSomnus, Inc. (formerly known as ProSomnus Holdings, Inc., DTI Holdings Inc. and MicroDental Inc.) was incorporated in 2006, for most of its history, its primary business was the operation of a chain of dental laboratories. In October 2016, it sold the dental laboratory business and retained the sleep apnea business it started in 2014, and formed ProSomnus Sleep Technologies, Inc. as a wholly owned subsidiary to operate that business. Accordingly, we have a limited operating history and must be evaluated in light of the uncertainties, risks, expenses, and difficulties frequently encountered by companies in their early stages of operations.

​

In addition, as a business with a limited operating history, we may encounter unforeseen expenses, difficulties, complications, delays, and other known and unknown obstacles. We have encountered in the past, and will encounter in the future, risks and uncertainties frequently experienced by growing companies with limited operating histories in emerging and rapidly changing industries. If our assumptions regarding these risks and uncertainties, which we use to plan and operate our business, are incorrect or change, or if we do not address these risks successfully, our results of operations could differ materially from our expectations, and our business, financial condition, and results of operations could be adversely affected.

​

We have a history of operating losses and may never achieve cash flow positive or profitable results of operations.

​

Since we began our ProSomnus business in 2016, we have not been profitable and have incurred losses and cash flow deficits. For the fiscal years ended December 31, 2022 and 2021, we reported net losses of $7.1 million and $6.0 million, respectively, and negative cash flow from operating activities of $10.3 million and $4.6 million, respectively. Accumulated deficit as of December 31, 2022 was $210.8 million.

​

We anticipate that we will continue to report losses and negative cash flow. There is therefore a risk that we will be unable to operate our business in a manner that generates positive cash flow or profit, and our failure to operate our business profitably could damage our reputation and stock price.

​

Based on cash flow projections from operating and financing activities and existing balance of cash and cash equivalents and investments, management is of the opinion that the Company has sufficient funds for sustainable operations, and it will be able to meet its payment obligations from operations and debt related commitments for at least one year from the issuance date of these financial statements.

​

The Company’s ability to continue as a going concern is dependent on management’s ability to control operating costs and maintain revenue growth forecast. However, additional funding will be necessary to fund future discovery research, pre-clinical and clinical activities. We will seek additional funding through public financings, debt financings, collaboration agreements, strategic alliances and licensing arrangements. Although we have been successful in raising capital in the past, there is no assurance that we will be successful in obtaining such additional financing on acceptable terms, or at all, and we may not be able to enter into collaborations or other arrangements. If we are unable to obtain funding, we could be forced to delay, reduce or eliminate our research and development programs, product portfolio expansion or commercialization efforts, which could adversely affect our business prospects, and even our ability to continue operations.

​

We have identified a historical material weakness in our internal control over financial reporting.

​

In connection with the audit of our consolidated financial statements for the years ended December 31, 2022 and 2021, our independent registered public accounting firms identified a material weakness in our internal control over financial reporting. A material weakness is a deficiency, or a combination of deficiencies, in internal control over financial reporting, such that there is a reasonable possibility that a material misstatement of our annual or interim financial statements will not be prevented or detected on a timely basis. The material weakness in our case arose from the accounting for certain complex transactions and a lack of expertise for such accounting issues. While remediation efforts have been made, if we are unable to remedy our material weakness, or if we generally fail to establish and maintain effective internal controls appropriate for a public company, we may be unable to produce timely and accurate financial statements, and we may conclude that our internal control over financial reporting is not effective, which could adversely impact our investors’ confidence and our stock price.

We will not be successful if our ProSomnus precision intraoral medical devices are not sufficiently adopted by the medical and dental communities for the treatment of Obstructive Sleep Apnea (OSA).

​

Our success depends both on the sufficient acceptance and adoption by the dental and medical communities of our ProSomnus precision intraoral medical devices as a non-invasive treatment for the treatment of mild to moderate OSA and potentially severe OSA in the future and on heightening public awareness of the prevalence of OSA to increase the number of undiagnosed patients who seek treatment. Currently, a relatively limited number of dentists and other medical professionals provide ProSomnus precision intraoral medical devices for the treatment of OSA. We cannot predict how quickly, if at all, the medical and dental communities will accept our precision intraoral medical devices, or, if accepted, the extent of their use.

​

For us to be successful:

​

​

​

​

​

Studies have shown that a significant percentage of people who have OSA remain undiagnosed and therefore do not seek treatment, or those who are diagnosed with OSA may be reluctant to seek treatment or incur significant costs of treatment given the less severe nature of their condition, the potentially negative lifestyle effects of Continuous Positive Airway Pressure (CPAP) and other traditional treatments, and the lack of awareness of new treatment options. If there is not an increase in public awareness of the prevalence of OSA or if the medical and dental communities are slow to adopt, or fail to adopt, ProSomnus precision intraoral medical devices as a treatment for individuals with OSA, we would suffer a material adverse effect on our business, financial condition, and results of operations.

​

We derive a substantial portion of our revenue from sales of a single type of product (ProSomnus precision intraoral medical devices) and expect to continue to do so, which leaves us reliant on the commercial viability of the ProSomnus precision intraoral medical devices.

​

Currently, our only products are ProSomnus precision intraoral medical devices. We expect a secondary source of revenue to be remote monitoring services, which we expect to introduce soon. We expect that sales of our ProSomnus precision intraoral medical devices will account for a significant amount of our revenue for the foreseeable future. We currently market and sell our ProSomnus precision intraoral medical devices primarily in the United States and Canada, with a very limited presence in very few select European countries and Australia. Because the ProSomnus precision intraoral medical devices are different from current surgical and non-surgical treatments for OSA, we cannot assure you that dentists in corroboration with physicians will use our products, and demand for our products may decline or may not increase as quickly as we expect. Also, we cannot assure you that the ProSomnus precision intraoral medical devices will compete effectively as a treatment alternative to other more well-known and well-established therapies, such as CPAP, palatal surgical procedures, or other oral appliance therapy devices.

​

Since our ProSomnus precision intraoral medical devices currently represent our only products, we are significantly reliant on the level of recurring sales of the ProSomnus precision intraoral medical devices and decreased or lower than expected sales or recruitment of physicians and sleep dentists to recommend our products would have a material adverse effect on our business, financial condition, and results of operations.

​

We expect to introduce remote monitoring services soon. We may be unable to launch these new services on time, at all, or without significant additional expense, and such services may not be as popular as we anticipated, which would have a material adverse effect on our business, financial condition, and results of operations.

We face risks relating to public health conditions such as the COVID-19 pandemic, which could adversely affect our dentist customers, sleep physicians, our business, and our results of operations.

​

Our business and prospects have been and could be materially adversely affected by the COVID-19 pandemic or recurrences of COVID-19 (such as the emergence of the Omicron variant in the United States in December 2021) or any other similar diseases in the future. Material adverse effects from COVID-19 and similar diseases could result in numerous known and currently unknown ways including from quarantines and lockdowns which impair our marketing and sales efforts to dentists or other medical professionals and limit patient visits to sleep dentists and physicians. During the COVID-19 pandemic, dental offices throughout the U.S. and Canada shut down for extended periods of time (and may be shut down again due to recurrences of COVID-19), thus negatively impacting our product revenues. The pandemic and reactions to the pandemic or future outbreaks of COVID-19 could also impair the timing of obtaining necessary consents and approvals from the FDA, as its employees could also be under such quarantines and lockdowns and their time could be mandatorily required to be allocated to more immediate global and domestic concerns relating to COVID-19. In addition, we purchase materials for our products from suppliers located in affected areas, and we may not be able to timely procure required materials. The effects of the COVID-19 pandemic have also placed travel restrictions on us, as well as temporary closures of the facilities of our suppliers as non-essential medical and dental procedures have been limited, which could also adversely impact our business. In addition, a significant outbreak of contagious diseases in the human population could result in a widespread health crisis that could adversely affect the economies and financial markets of many countries, resulting in an economic downturn that could reduce the demand for our products and impair our business prospects including being unable to raise additional capital on acceptable terms to us, if at all.

​

We may not be able to successfully implement our growth strategy by successfully attracting sleep dentists and sleep physicians on a timely basis or at all, which could harm our business, financial condition, and results of operations.

​

The growth of our business depends on our ability to execute our plan to attract new sleep dentists and sleep physicians. Our ability to recruit sleep dentists and sleep physicians depends on many factors, including our ability to:

​

​

​

​

​

​

​

​

​

​

Further, applicable laws, rules, and regulations (including licensure requirements) could negatively impact our ability to recruit sleep dentists that provide our devices to their patients.

​

Accordingly, we may not be able to achieve our planned growth or, even if we are able to grow our base of sleep dentists as planned, we may not be profitable or otherwise perform as planned. We may also struggle to recruit and train ProSomnus employees which could limit our ability to deliver product in a timely manner. Failure to successfully implement our growth strategy would likely have an adverse impact on our business, financial condition, and results of operations.

​

Our sales and marketing efforts may not be successful.

​

We currently market and sell our ProSomnus precision intraoral medical devices to a limited number of licensed professionals, primarily sleep dentists. Approximately 2.4% of dentists in the United States have been trained in providing our ProSomnus precision intraoral medical devices. The commercial success of our ProSomnus precision intraoral medical devices ultimately depends upon a

Table of Contents

number of factors, including the number of sleep dentists who provide our ProSomnus precision intraoral medical devices to their patients, the number of devices provided by these dentists, the number of patients who become aware of our ProSomnus precision intraoral medical devices by self-referral or referrals by their primary care or sleep physicians, the number of patients who elect to use our ProSomnus precision intraoral medical devices, and the number of patients who, having successfully used our ProSomnus precision intraoral medical devices, endorse and refer our ProSomnus precision intraoral medical devices to other potential patients..

​

Although we sell our products directly to sleep dentists, our experience in marketing and selling our ProSomnus precision intraoral medical devices through a direct sales organization in the United States is limited. We may not be able to maintain a suitable sales force in the United States or internationally or train a suitable number of sleep dentists and physicians. Our marketing and sales efforts may not be successful in increasing awareness and sales of our ProSomnus precision intraoral medical devices.

​

The failure to educate or train a sufficient number of physicians and dentists in the use of our ProSomnus precision intraoral medical devices could reduce the market acceptance of our ProSomnus precision intraoral medical devices and reduce our revenue.

​

It is critical to the success of our sales efforts that there is an increasing number of sleep dentists and sleep physicians familiar with, trained in, and proficient in the use of our ProSomnus precision intraoral medical devices. Currently, sleep dentists learn to use our ProSomnus precision intraoral medical devices through hands-on, on-site training or virtual training by our representatives. However, to receive this training, dentists must be aware of our ProSomnus precision intraoral medical devices as a treatment option for OSA and be interested in using our ProSomnus precision intraoral medical devices in their practice. We cannot predict the extent to which dentists will dedicate the time and energy necessary for adequate training in the use of our ProSomnus precision intraoral medical devices, have the knowledge of or experience in the clinical outcomes of our ProSomnus precision intraoral medical devices, or feel comfortable enough using our ProSomnus precision intraoral medical devices to recommend it to their patients. Even if a dentist is well versed in our ProSomnus precision intraoral medical devices, he or she may be unwilling to require patients to pay for the oral device out-of-pocket if not covered by medical insurance. If dentists do not continue to accept and recommend our ProSomnus precision intraoral medical devices, our revenue could be materially and adversely affected.

​

Our marketing activities may not be successful.

​

We incur costs and expend other resources in our marketing efforts to attract and retain sleep dentists, referring physicians and patients. Our marketing activities are principally focused on increasing brand awareness in the communities in which we provide services. We expect to undertake marketing campaigns to increase awareness about our presence and our service capabilities. If we are not successful in these efforts, we will have incurred expenses without materially increasing revenue.

​

Our future operating results are difficult to predict and may vary significantly from quarter to quarter, which may adversely affect the price of our Common Stock.

​

Our limited history of sales of our ProSomnus precision intraoral medical devices, together with our history of losses, make prediction of future operating results difficult. You should not rely on our past revenue growth as any indication of future growth rates or operating results. Our valuation and the price of our securities likely will fall in the event our operating results do not meet the expectations of analysts and investors. Comparisons of our quarterly operating results are an unreliable indication of our future performance because they are likely to vary significantly based on many factors, including:

​

​

​

We may not be able to respond in a timely and cost-effective manner to changes in the preferences of physicians, dental sleep medicine providers or patients.

​

Our ProSomnus precision intraoral medical devices are subject to changing preferences of both physicians and dental sleep medicine providers that provide our precisions intraoral medical devices to patients and the patients themselves. A shift in preferences away from the precision intraoral medical devices we offer would result in our results of operations in future periods to be materially adversely impacted.

​

Further clinical studies of our ProSomnus precision intraoral medical devices may adversely impact our ability to generate revenue if they do not demonstrate that our devices are clinically effective for currently specified or expanded indications or if they are not completed in a timely manner.

​

We have conducted a number of clinical studies of the use of our ProSomnus precision intraoral medical devices to treat patients with mild to moderate OSA in the United States and Canada. We are also involved in a number of ongoing clinical studies evaluating clinical outcomes from the use of our ProSomnus precision intraoral medical devices, including prospective, randomized, placebo-controlled studies, as well as clinical studies that are structured to obtain additional clearances from the FDA for expanded clinical indications for use of our ProSomnus precision intraoral medical devices, including for the treatment of severe OSA.

​

We cannot assure you that these clinical studies will continue to demonstrate that our ProSomnus precision intraoral medical devices provide clinical effectiveness for individuals diagnosed with mild to moderate OSA or will demonstrate that such devices also provide clinical effectiveness for individuals diagnosed with severe OSA, nor can we assure you that the use of our ProSomnus precision intraoral medical devices will prove to be safe and effective in clinical studies under United States or international regulatory guidelines for any expanded indications. Additional clinical studies of our ProSomnus precision intraoral medical devices may identify significant clinical, technical, or other obstacles that will have to be overcome prior to obtaining clearance from the applicable regulatory bodies to market our ProSomnus precision intraoral medical devices for such expanded indications.

​

Individuals selected to participate in these further clinical studies must meet certain anatomical and other criteria to participate. We cannot assure you that an adequate number of individuals can be enrolled in clinical studies on a timely basis. Further, we cannot assure you that the clinical studies will be completed as planned. A delay in the analysis and publication of the positive outcomes data from these clinical studies, or the presentation or publication of negative outcomes data from these clinical studies, including data related to

Table of Contents

approval of our ProSomnus precision intraoral medical devices for expanded indications, may materially impact our ability to increase revenue through sales and negatively impact our stock price.

​

Our business and results of operations may be impacted by the extent to which patients using our ProSomnus precision intraoral medical devices achieve adequate levels of third-party insurance reimbursement.

​

The cost of treatments for OSA, such as CPAP, and most surgical procedures generally are covered and reimbursed in whole or part by third-party healthcare insurers. Our ProSomnus precision intraoral medical devices are customized oral appliances, most of which currently qualify for reimbursement for the treatment of mild to moderate OSA. Our ability to generate future revenue from additional sales of our ProSomnus precision intraoral medical devices and remote monitoring services for the treatment of OSA may be materially limited by the extent to which reimbursement of our ProSomnus precision intraoral medical devices and remote monitoring services for the treatment of OSA is available in the future. In addition, third-party healthcare insurers are increasingly challenging the prices charged for medical products and procedures. Any changes in this reimbursement system or reimbursement levels could materially affect our ability to continue to grow our business.

​

Reimbursement and healthcare payment systems in international markets vary significantly by country and reimbursement for our ProSomnus precision intraoral medical devices may not be available at all under either government or private reimbursement systems. If we are unable to achieve reimbursement approvals in international markets, it could have a negative impact on market acceptance of our ProSomnus precision intraoral medical devices and potential revenue growth in the markets in which these approvals are sought.

​

We face significant competition in the rapidly changing market for treating OSA, and we may be unable to manage competitive pressures.

​

The market for treating OSA, including sleep apnea in people of all ages, is highly competitive and evolving rapidly. We compete as a front-line therapy in the OSA treatment market for patients with mild to moderate OSA. According to the American Sleep Apnea Association, over 100 different oral appliances are FDA cleared for the treatment of snoring and obstructive sleep apnea. Our ProSomnus precision intraoral medical devices must compete with more established products, treatments, and surgical procedures, which may limit our growth and negatively affect our business. Many of our competitors have an established presence in the field of treating OSA and have established relationships with pulmonologists, sleep clinics, and ear, nose and throat specialists (ENTs), which play a significant role in determining which product, treatment, or procedure is recommended to the patient. We believe certain of our competitors are attempting to develop innovative approaches and new products for diagnosing and treating. We cannot predict the extent to which ENTs, oral maxillofacial surgeons, primary care physicians, or pulmonologists would or will recommend our ProSomnus precision intraoral medical devices over new or other established devices, treatments, or procedures.

​

Moreover, we are in the early stages of implementing our business plan and have historically had limited resources with which to market, develop and sell our ProSomnus precision intraoral medical devices. Many of our competitors have substantially greater financial and other resources than we do, including larger research and development staffs who have more experience and capability in conducting research and development activities, testing products in clinical trials, obtaining regulatory approvals, and manufacturing, marketing, selling, and distributing products. Some of our competitors may achieve patent protection, regulatory approval, or product commercialization more quickly than we do, which may decrease our ability to compete. If we are unable to be competitive in the market for OSA, our revenue will decline, which would negatively affect our results of operations.

​

Our ProSomnus precision intraoral medical devices may become obsolete if we are unable to anticipate and adapt to rapidly changing technology.

​

The medical device industry is subject to rapid technological innovation and, consequently, the life cycle of any particular product can be short. Alternative products, procedures, or other discoveries and developments to treat OSA may render our ProSomnus precision intraoral medical devices obsolete.

​

Furthermore, the greater financial and other resources of many of our competitors may permit them to respond more rapidly than we can to technological advances. If we fail to develop new technologies, products, or services to upgrade or improve our existing ProSomnus precisions intraoral medical devices to respond to a changing market before our competitors are able to do so, our ability to market our products and generate substantial revenue may be limited.

​

Our potential international sales are subject to a number of risks that could seriously harm our ability to successfully commercialize our ProSomnus precision intraoral medical devices in international markets.

​

We do not have any significant international sales outside of Canada, although we hope to more broadly introduce our ProSomnus precision intraoral medical devices into international markets in the future. Our ability to generate international sales is subject to several risks, including:

​

​

​

​

​

​

​

​

​

The occurrence of any of these events could seriously harm our future international sales and our ability to successfully commercialize our products in international markets, thereby limiting our growth and revenue.

​

We maintain supply relationships for certain of our key manufacturing systems and raw materials, and our business and operating results could be harmed if supply is restricted or ends or the price of raw materials used in our manufacturing process increases.

​

We are highly dependent on manufacturers of specialized oral scanning equipment, milling machines, and advanced medical grade raw materials for the fabrication of our precision intraoral medical devices. We maintain supply relationships for many of these systems and materials. We are also committed to purchasing the vast majority of our advanced medical grade Class VI polymer, the primary raw material used in our manufacturing of our precision intraoral medical devices, from a certain sources. While it is our goal to have multiple sources to procure certain key components, in some cases it may not be economically practical or feasible to do so. To mitigate this risk, we maintain an awareness of alternate supply sources that could provide our components with minimal or no modification to the current version of our precision intraoral medical devices, practice supply chain management, maintain safety stocks of critical components and have arrangements with our key vendors to manage the availability of critical components. If these or other suppliers encounter financial, operating, or other difficulties or if our relationship with them changes, we might not be able to quickly establish or qualify replacement sources of supply and could face production interruptions, delays, and inefficiencies. In addition, technological changes by our vendors could disrupt our manufacturing process or require expensive, time-consuming development efforts to adapt and integrate new equipment or processes. Our growth may exceed the capacity of one or more of these manufacturers to produce the needed equipment and materials in sufficient quantities to support our growth. Conversely, in order to secure supplies for production of our precision intraoral medical devices, we sometimes enter into non-cancelable purchase commitments with vendors, which could impact our ability to adjust our inventory to reflect declining market demands. If demand for our products is less than we expect, we may experience additional excess and obsolete inventories and be forced to incur additional charges and our profitability may suffer. In the event of technology changes, delivery delays, or shortages of or increases in price for these items, our business and growth prospects may be harmed.

​

The failure of dentists to pay for their purchases of our ProSomnus precision intraoral medical devices on a timely basis could reduce our future revenue and negatively impact our liquidity.

​

The timing and extent of our future growth in revenue depends, in part, on our ability to continue to increase the number of sleep dentists using our ProSomnus precision intraoral medical devices, as well as expanding the number of our ProSomnus precision intraoral medical devices used by these dentists. To the extent one or more of our large dentist customers fails to pay us for our ProSomnus precision intraoral medical devices on a timely basis, we may be required to discontinue selling to these dentists and find new customers, which could reduce our future revenue and negatively impact our liquidity.

​

Our revenues may depend on our patients’ and providers’ receipt of adequate reimbursement from private insurers and government sponsored healthcare programs.

​

Political, economic, and regulatory influences continue to change the medical device industry in the United States. The ability of patients to pay fees for our devices will partially depend on the extent to which reimbursement for the costs of such materials and related

Table of Contents

treatments will continue to be available from private health coverage insurers and other similar organizations. We may have difficulty gaining market acceptance for the products we sell if third-party payors do not provide adequate coverage and reimbursement to physicians and care providers. Major third-party payors, such as private healthcare insurers, periodically revise their payment methodologies based, in part, upon changes in government sponsored healthcare programs. We cannot predict these periodic revisions with certainty, and such revisions may result in adverse changes to reimbursement for certain specified devices, potentially adversely impacting our business, results of operations, and financial conditions.

​

The sales of our devices will depend in part on the availability of reimbursement by third-party payors, such as government health administration authorities, private health insurers and other organizations. Third-party payors often challenge the price and cost-effectiveness of medical devices and services. Governmental approval of medical products does not guarantee that these third-party payors will pay for the products. Even if third-party payors do accept our medical devices, the amounts they pay may not be adequate to enable us to realize a profit. Legislation and regulations affecting the pricing of devices may change before our products and services are approved for marketing, and any such changes could further limit reimbursement, if any.

​

We face the risk of product liability claims that could be expensive, divert management’s attention, and harm our reputation and business.

​

Our business exposes us to the risk of product liability claims that are inherent in the testing, manufacturing, and marketing of medical devices. This risk exists even if a device is cleared or approved for commercial sale by the FDA and manufactured in facilities licensed and regulated by the FDA or an applicable foreign regulatory authority. Our ProSomnus precision intraoral medical devices are designed to affect, and any future products will be designed to affect, important bodily functions and processes. Any side effects, manufacturing defects, misuse, or abuse associated with our ProSomnus precision intraoral medical devices could potentially result in patient injury or death. The medical device industry has historically been subject to extensive litigation over product liability claims, and we cannot offer any assurance that we will not face product liability suits. We may be subject to product liability claims if our ProSomnus precision intraoral medical devices cause, or merely appear to have caused, patient injury or death. In addition, an injury that is caused by the activities of our suppliers, such as those who provide us with components and raw materials, may be the basis for a claim against us. Product liability claims may be brought against us by patients, healthcare providers, or others selling or otherwise coming into contact with our ProSomnus precision intraoral medical devices, among others. If we cannot successfully defend ourselves against product liability claims, we will incur substantial liabilities and reputational harm. In addition, regardless of merit or eventual outcome, product liability claims may result in:

​

​

​

​

​

​

​

​

​

Any recall or market withdrawal of our products may delay the supply of those products to our customers and may impact our reputation. We can provide no assurance that we will be successful in initiating appropriate market recall or market withdrawal efforts that may be required in the future or that these efforts will have the intended effect of preventing product malfunctions and the accompanying product liability that may result. Such recalls and withdrawals may also be used by our competitors to harm our reputation for safety or be perceived by patients as a safety risk when considering the use of our products, either of which could have a material adverse effect on our business, financial condition, and results of operations.

​

We may not be able to maintain adequate product liability insurance.

​

Our product liability and clinical study liability insurance is subject to deductibles and coverage limitations. Our product liability insurance may not continue to be available to us on acceptable terms, if at all, and, if available, coverage may not be adequate to protect us against any future product liability claims. If we are unable to obtain insurance at an acceptable cost or on acceptable terms or otherwise protect against potential product liability claims, we could be exposed to significant liabilities.

Table of Contents

​

We bear the risk of warranty claims on our ProSomnus precision intraoral medical devices.

​

We bear the risk of warranty claims on our ProSomnus precision intraoral medical devices. 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 or patients 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.

​

Risks Related to Intellectual Property

​

We depend on our patents and proprietary technology, which we may not be able to protect.

​

Our success depends, in part, on our ability to obtain and maintain patent protection for our ProSomnus precision intraoral medical devices and our manufacturing process and the confidentiality of proprietary technology. Our success further depends on our ability to obtain and maintain trademark protection for our name and mark, to preserve our trade secrets and know-how, and to operate without infringing the intellectual property rights of others.

​

We cannot assure investors that we will continue to innovate and file new patent applications, or that if any filed future patent applications will result in granted patents. We cannot assure you that any of our patents pending will result in issued patents, that any current or future patents will not be challenged, invalidated, or circumvented, that the scope of any of our patents will exclude competitors or that the patent rights granted to us will provide us any competitive advantage or protect our products. The patent position of device companies, including ours, is generally uncertain and involves complex legal and factual considerations and, therefore, validity and enforceability cannot be predicted with certainty. Patents may be challenged, deemed unenforceable, invalidated, or circumvented. We will be able to protect our proprietary rights from unauthorized use by third parties only to the extent that our proprietary technologies, protocols and any future products are covered by valid and enforceable patents or are effectively maintained as trade secrets.

​

Any patents we have obtained or do obtain may be challenged by re-examination or otherwise invalidated or eventually found unenforceable. Both the patent application process and the process of managing patent disputes can be time consuming and expensive. If we were to initiate legal proceedings against a third party to enforce a patent related to one of our products, the defendant in such litigation could counterclaim that our patent is invalid and/or unenforceable. In patent litigation in the United States, defendant counterclaims alleging invalidity and/or unenforceability are commonplace, as are validity challenges by the defendant against the subject patent or other patents before the United States Patent and Trademark Office (“USPTO”). Grounds for a validity challenge could be an alleged failure to meet any of several statutory requirements, including lack of novelty, obviousness, or non-enablement, failure to meet the written description requirement, indefiniteness, and/or failure to claim patent eligible subject matter. Grounds for an unenforceability assertion could be an allegation that someone connected with prosecution of the patent intentionally withheld material information from the USPTO, or made a misleading statement, during prosecution. Additional grounds for an unenforceability assertion include an allegation of misuse or anticompetitive use of patent rights, and an allegation of incorrect inventorship with deceptive intent. Third parties may also raise similar claims before the USPTO even outside the context of litigation. The outcome is unpredictable following legal assertions of invalidity and unenforceability. With respect to the validity question, for example, we cannot be certain that no invalidating prior art existed of which we and the patent examiner were unaware during prosecution. These assertions may also be based on information known to us or the USPTO. If a defendant or third party were to prevail on a legal assertion of invalidity and/or unenforceability, we would lose at least part, and perhaps all, of the claims of the challenged patent. Such a loss of patent protection would or could have a material adverse impact on our business.

​

The standards that the USPTO (and foreign equivalents) use to grant patents are not always applied predictably or uniformly and can change. There is also no uniform, worldwide policy regarding the subject matter and scope of claims granted or allowable in device patents. Accordingly, we do not know the degree of future protection for our proprietary rights or the breadth of claims that will be allowed in any patents issued to us or to others.

​

However, there can be no assurance that our technology will not be found in the future to infringe upon the rights of others or be infringed upon by others. Moreover, patent applications are in some cases maintained in secrecy until patents are issued. The publication of discoveries in the scientific or patent literature frequently occurs substantially later than the date on which the underlying discoveries were made and patent applications were filed. Because patents can take many years to issue, there may be currently pending applications of which we are unaware that may later result in issued patents that our products or product candidates infringe. For example, pending applications may exist that provide support or can be amended to provide support for a claim that results in an issued patent that our product infringes. In such a case, others may assert infringement claims against us, and should we be found to infringe upon their patents, or otherwise impermissibly utilize their intellectual property, we might be forced to pay damages, potentially including treble damages, if we are found to have willfully infringed on such parties’ patent rights.

Table of Contents

​

In addition to any damages we might have to pay, we may be required to obtain licenses from the holders of this intellectual property. We may fail to obtain any of these licenses or intellectual property rights on commercially reasonable terms. Even if we are able to obtain a license, it may be non-exclusive, thereby giving our competitors access to the same technologies licensed to us. In that event, we may be required to expend significant time and resources to develop or license replacement technology. If we are unable to do so, we may be unable to develop or commercialize the affected products, which could materially harm our business and the third parties owning such intellectual property rights could seek either an injunction prohibiting our sales, or, with respect to our sales, an obligation on our part to pay royalties and/or other forms of compensation. Conversely, we may not always be able to successfully pursue our claims against others that infringe upon our technology. Thus, the proprietary nature of our technology or technology licensed by us may not provide adequate protection against competitors.

​

In addition to patents, we rely on trademarks to protect the recognition of our company and products in the marketplace. We also rely on trade secrets, know-how, and proprietary knowledge that we seek to protect, in part, through confidentiality agreements with employees, consultants and others. We cannot assure you that our proprietary information will not be shared, our confidentiality agreements will not be breached, that we will have adequate remedies for any breach, or that our trade secrets will not otherwise become known to or independently developed by competitors.

​

Confidentiality agreements with employees and others may not adequately prevent disclosure of trade secrets and other proprietary information and disclosure of our trade secrets or proprietary information could compromise any competitive advantage that we have, which could have a materially adverse effect on our business.

​

Our success depends, in part, on our ability to protect our proprietary rights to the technologies used in our products and our proprietary technology. We depend heavily upon confidentiality agreements with our officers, employees, consultants, and subcontractors to maintain the proprietary nature of our technology. These measures may not afford us complete or even sufficient protection and may not afford an adequate remedy in the event of an unauthorized disclosure of confidential information. If we fail to protect and/or maintain our intellectual property, third parties may be able to compete more effectively against us, we may lose our technological or competitive advantage, and/or we may incur substantial litigation costs in our attempts to recover or restrict use of our intellectual property. In addition, others may independently develop technology similar to ours, otherwise avoiding the confidentiality agreements, or produce patents that would materially and adversely affect our business.

​

We may face intellectual property infringement claims that would be costly to resolve.

​

There has been substantial litigation regarding patent and other intellectual property rights in the medical device industry, and our competitors and others may initiate intellectual property litigation, including as a means of competition. Intellectual property litigation is complex and expensive, and outcomes are difficult to predict. We cannot assure you that we will not become subject to patent infringement claims, litigation, or interference proceedings to determine the priority of inventions. Litigation or regulatory proceedings also may be necessary to enforce our patent or other intellectual property rights. We may not always have the financial resources to assert patent infringement suits or to defend ourselves from claims. An adverse result in any litigation could subject us to liabilities or require us to seek licenses from or pay royalties to others that may be substantial. Furthermore, we cannot predict the extent to which the necessary licenses would be available to us on satisfactory terms, if at all.

​

Our failure to secure trademark registrations could adversely affect our ability to market our products and operate our business.

​

Our trademark applications in the United States and any other jurisdictions where we may file may not be allowed registration, and we may not be able to maintain or enforce our registered trademarks. During trademark registration proceedings, we may receive rejections. Although we are given an opportunity to respond to those rejections, we may be unable to overcome such rejections. In addition, in the USPTO and in corresponding foreign agencies, 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 applications and/or registrations, and our applications and/or registrations may not survive such proceedings. Failure to secure such trademark registrations in the United States and in foreign jurisdictions could adversely affect our ability to market our products and our business.

​

We may be subject to claims that our employees have wrongfully used or disclosed alleged trade secrets of their former employers.

​

As is common in the medical device industry, we may employ individuals who were previously employed at other companies similar to ours, including our competitors or potential competitors. We may become subject to claims that these employees or we have inadvertently or otherwise used or disclosed trade secrets or other proprietary information of their former employers. Litigation may be necessary to defend against these claims. Even if we are successful in defending against these claims, litigation could result in substantial costs and be a distraction to management.

Risks Related to Government and Regulation

​

Our failure to obtain government approvals, including required FDA approvals, or to comply with ongoing governmental regulations relating to our technologies and products could delay or limit introduction of our products and result in failure to achieve revenue or maintain our ongoing business.

​

Our development activities and the manufacture and marketing of our ProSomnus precision intraoral medical devices are subject to extensive regulation for safety, efficacy, and quality by numerous government authorities in the United States and internationally. Before receiving FDA or foreign regulatory clearance to market our products which are not presently approved, we will have to demonstrate that these products are safe and effective in the patient population and for the indications that are to be treated. Clinical trials, manufacturing, and marketing of medical devices are subject to the rigorous testing and approval process of the FDA and equivalent foreign regulatory authorities. The Federal Food, Drug, and Cosmetic Act and other federal, state, and foreign statutes and regulations govern and influence the testing, manufacture, labeling, advertising, distribution, and promotion of medical devices. As a result, regulatory approvals for our products not yet approved or that we may develop in the future can take a number of years or longer to accomplish and require the expenditure of substantial financial, managerial, and other resources.

​

Clinical trials that may be required to support regulatory submissions in the United States are expensive. We cannot assure that we will be able to complete any required additional clinical trial programs successfully within any specific time period, and if such clinical trials take longer to complete than we project, our ability to execute our current business strategy will be adversely affected.

​

Conducting clinical trials is a lengthy, time-consuming, and expensive process. Before obtaining regulatory approvals for the commercial sale of any products, we must demonstrate through clinical trials the safety and effectiveness of our products. We have incurred, and we will continue to incur, substantial expense for, and devote a significant amount of time to, product development, pilot trial testing, clinical trials, and regulated, compliant manufacturing processes.

​

Even if completed, we do not know if these trials will produce statistically significant or clinically meaningful results sufficient to support an application for marketing approval. If and how quickly we complete clinical trials is dependent in part upon the rate at which we are able to advance the rate of patient enrollment, and the rate to collect, clean, lock, and analyze the clinical trial database.

​

Patient enrollment in trials is a function of many factors. These include the design of the protocol; the size of the patient population; the proximity of patients to and availability of clinical sites; the eligibility criteria for the study; the perceived risks and benefits of the product candidate under study; the medical investigators’ efforts to facilitate timely enrollment in clinical trials; the patient referral practices of local physicians; the existence of competitive clinical trials; and whether other investigational, existing, or new products are available or cleared for the indication. If we experience delays in patient enrollment and/or completion of our clinical trial programs, we may incur additional costs and delays in our development programs and may not be able to complete our clinical trials on a cost-effective or timely basis. Accordingly, we may not be able to complete the clinical trials within an acceptable time frame, if at all. If we fail to enroll and maintain the number of patients for which the clinical trial was designed, the statistical power of that clinical trial may be reduced, which would make it harder to demonstrate that the product candidate being tested in such clinical trial is safe and effective. Further, if we or any third party have difficulty enrolling a sufficient number of patients in a timely or cost-effective manner to conduct clinical trials as planned, or if enrolled patients do not complete the trial as planned, we or a third party may need to delay or terminate ongoing clinical trials, which could negatively affect our business.

​

The results of our clinical trials may not support either further clinical development or the commercialization of any new product candidates or modifications to existing products.

​

Even if our ongoing or contemplated clinical trials are completed as planned, their results may not support either the further clinical development or the commercialization of any new product candidates or modifications of existing products. The FDA or government authorities may not agree with our conclusions regarding the results of our clinical trials. Success in preclinical testing and early clinical trials does not ensure that later clinical trials will be successful, and the results from any later clinical trials may not replicate the results of prior clinical trials and pre-clinical testing. The clinical trial process may fail to demonstrate that our product candidates are safe and effective for indicated uses. This failure would cause us to abandon a product candidate or a modification to any existing product and may delay development of other product candidates. Any delay in, or termination of, our clinical trials could delay the filing of our 510(k)’s and, ultimately, our ability to commercialize our product candidates and generate product revenue. Each Class I and Class II medical device marketed in the United States must receive a 510(k) clearance from the FDA. A 510(k) is a premarket submission made to FDA to demonstrate that the device to be marketed is at least as safe and effective as, or substantially equivalent to, a legally marketed device. Companies must compare their device to one or more similar legally marketed devices, commonly known as “predicates,” and make and support their substantial equivalency claims. The submitting company may not proceed with product marketing until it receives an order from the FDA declaring a device substantially equivalent.

The substantially equivalent determination is usually made within 90 days and is based on the information submitted by the applicant.

​

In addition, we or the FDA may suspend our clinical trials at any time if it appears that we are exposing participants to unacceptable health risks or if the FDA finds deficiencies in the conduct of these trials. A number of companies in the medical technology industry have suffered significant setbacks in advanced clinical trials despite promising results in earlier trials. In the end, we may be unable to develop marketable products.

​

Modifications to our ProSomnus precision intraoral medical devices may require additional FDA approvals which, if not obtained, could force us to cease marketing and/or recall the modified device until we obtain new approvals.

​

After a device receives a 510(k) clearance, any modification that could significantly affect its safety or effectiveness, or that would constitute a major change in its intended use, requires a new 510(k) clearance or could require a premarket approval (“PMA”). PMA is the FDA process of scientific and regulatory review to evaluate the safety and effectiveness of Class III medical devices. Class III devices are those that support or sustain human life, are of substantial importance in preventing impairment of human health, or which present a potential, unreasonable risk of illness or injury. Currently, we do not market devices within this Class III category, nor do we intend to in the foreseeable future. However, the FDA requires each manufacturer to make this determination in the first instance, but the FDA can review any decision. If the FDA disagrees with a manufacturer’s decision not to seek a new 510(k) clearance, the agency may retroactively require the manufacturer to seek 510(k) clearance or PMA approval. The FDA also can require the manufacturer to cease marketing and/or recall the modified devices until 510(k) clearance or PMA approval is obtained. We cannot assure you that the FDA would agree with any of our decisions not to seek 510(k) clearance or PMA approval. If the FDA requires us to seek 510(k) clearance or PMA approval for any modification, we also may be required to cease marketing and/or recall the modified device until we obtain a new 510(k) clearance or PMA approval.

​

Our ProSomnus precision intraoral medical device has received 510(k) Class II clearance from the FDA for treating mild to moderate OSA and snoring in adults.

​

We are subject to inspection and market surveillance by the FDA to determine compliance with regulatory requirements. If the FDA finds that we have failed to comply, the agency can institute a wide variety of enforcement actions which may materially affect our business operations.

​

Although we are not currently subject to any FDA warning letters, censures or audits, we are subject to inspection and market surveillance by the FDA to determine compliance with regulatory requirements. If the FDA finds that we have failed to comply, the agency can institute a wide variety of enforcement actions, ranging from a public warning letter to more severe sanctions such as:

​

​

​

​

​

​

​

​

The FDA also has the authority to request repair, replacement, or refund of the cost of any medical device manufactured or distributed by us. Our failure to comply with applicable requirements could lead to an enforcement action that may have an adverse effect on our financial condition and results of operations.

Our ProSomnus precision intraoral medical devices are subject to extensive governmental regulation that could prevent us from selling our ProSomnus precision intraoral medical devices or introducing new and/or improved products and services in the United States or internationally.

​

Our precision intraoral medical devices, manufacturing activities, and remote monitoring services are subject to extensive regulation by a number of governmental agencies, including the FDA and comparable international regulatory bodies. We are required to:

​

​

​

​

Compliance with the rules and regulations of these various regulatory bodies may delay or prevent us from introducing any new models of our ProSomnus precision intraoral medical devices or other new products or services. In addition, government regulations may be adopted that could prevent, delay, modify, or rescind regulatory clearance or approval of our products.

​

Our manufacturing activities are further required to demonstrate compliance with the FDA’s quality system regulations. The FDA enforces their quality system regulations through pre-approval and periodic post- approval inspections by representatives from the FDA. These regulations relate to product testing, vendor qualification, design control, and quality assurance, as well as the maintenance of records and documentation.

​

If we fail to conform to these regulations, the FDA may take actions that could seriously harm our business. These actions include sanctions, including temporary or permanent suspension of our operations, product recalls and marketing restrictions. A recall or other regulatory action could substantially increase our costs, damage our reputation, and materially affect our operating results.
