Item 1. Business.

Overview

We are a medical technology company focused on the development and commercialization of innovative, minimally invasive solutions for patients with obstructive sleep apnea ("OSA"). Our proprietary Inspire system is the first FDA, European Union ("EU") Regulation No. 2017/745 ("MDR" or "EU Medical Devices Regulation"), and Japan Pharmaceuticals and Medical Devices Agency-approved neurostimulation technology of its kind that provides a safe and effective treatment for patients with moderate to severe OSA. We have developed a novel, closed-loop solution that continuously monitors a patient’s breathing and delivers mild hypoglossal nerve stimulation to maintain an open airway. A significant body of clinical data, which includes a publication in the New England Journal of Medicine, multiple publications in leading respiratory, ear, nose and throat ("ENT") and sleep medicine journals, and more than 385 peer-reviewed publications, supports the safety and efficacy of Inspire therapy. Inspire therapy received premarket approval ("PMA") from the FDA in 2014 and has been commercially available in certain European markets since 2011. Japan's Ministry of Health, Labour and Welfare ("MLHW") approved Inspire therapy to treat moderate to severe OSA in 2018. Inspire therapy is indicated for patients with moderate to severe OSA who do not have significant central sleep apnea and do not have a complete concentric collapse of the airway at the soft palate level. Physicians have treated more than 125,000 patients with Inspire therapy across the United States ("U.S."), Europe, and Asia.

Sleep apnea is a serious and chronic disease that negatively impacts a patient’s sleep, health, and quality of life. OSA is the most common form of sleep apnea. OSA occurs when a person’s breathing is interrupted during sleep by a partially or completely blocked airway and affects patients of all ages, sexes, and body types. The severity of OSA is measured by the number of partial or complete airway blockages that a patient experiences in an hour, referred to as the apnea-hypopnea index ("AHI"). Moderate OSA patients have an AHI of 15 to 30 events per hour, while severe OSA patients have an AHI of 30 more events per hour. Left untreated, OSA increases the risk of high blood pressure, hypertension, heart failure, stroke, coronary artery disease, and other life-threatening diseases.

Continuous positive airway pressure ("CPAP") is the leading therapy for patients with moderate to severe OSA. CPAP is delivered through a face or nasal mask that connects through a hose to a bedside air pump. In order for 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. The effectiveness of CPAP has been limited by low patient compliance as many patients find the mask or treatment cumbersome, uncomfortable, and loud. When CPAP fails or cannot be tolerated, patients’ remaining treatment options consist primarily of invasive surgical procedures developed to modify or remove existing tissue in an attempt to create free air flow. These invasive surgical procedures have limited or unpredictable clinical benefit, are irreversible, and can be extremely painful.

We believe that there continues to be both an urgent clinical need and a strong market opportunity for an alternative to CPAP that is effective and minimally invasive. Data shows that patients with CPAP intolerant OSA have a higher risk for mortality than patients with CPAP-tolerant OSA and higher healthcare utilization rates based on increased cardiovascular health risks. Two findings published in 2022 from Medicare and the French national healthcare insurance databases have demonstrated, in large national cohorts, risks of CPAP intolerance. Specifically, Medicare patients with CPAP intolerance had higher risks of new cardiovascular events than those who were adherent. Similarly, the French national reimbursement database showed that in over 176,000 patients, CPAP non-adherent patients had a higher risk for mortality and new onset of heart failure than those who were adherent. These findings show the urgency of treating CPAP-intolerant OSA to improve patient outcomes and potentially reduce healthcare utilization.

Inspire therapy is an innovative, closed-loop, minimally invasive solution designed to provide comfort and convenience, and which results in high compliance for patients with moderate to severe OSA. Once implanted, the Inspire system delivers electrical stimulation that causes a slight forward movement of the back of the tongue, which helps to maintain an open airway, enabling the patient to inhale freely without interruption. We believe our Inspire therapy provides the following benefits:

Table of Contents

•Safe, effective, and durable treatment supported by compelling clinical data, including long-term efficacy results out to five years from initial treatment.

•Closed-loop system that uses a proprietary algorithm to continuously monitor patients’ breathing and provide electrical stimulation during the inspiratory phase.

•Comfortable and convenient therapy resulting in high patient satisfaction that was reported to be 90% in patients who were followed an average of 12 months from initial treatment, according to the most recent publication of our ongoing global patient registry.

•Strong patient compliance, with 80% of patients reporting continued nightly use through five years from initial treatment in our Stimulation Therapy for Apnea Reduction ("STAR") trial.

•Minimally invasive outpatient procedure with short recovery time.

•Long-lasting solution with a battery designed to last approximately 11 years without charging or maintenance.

The results from multiple clinical studies, which include seven sponsored and more than 100 independent clinical studies that evaluated several thousand patients, have shown that our Inspire therapy provides statistically significant and sustained reduction in the severity of patients’ OSA, improvement in sleep-related quality of life and reduction in snoring, as well as high patient compliance rates and a strong safety profile.

Our pivotal STAR trial was designed to demonstrate longitudinal therapy efficacy and included a randomized controlled therapy withdrawal study. The longitudinal study demonstrated an approximately 70% reduction in the median AHI in patients with moderate to severe OSA from a baseline of 29.3 events per hour to 9.0 events per hour at 12 months following initial treatment. STAR trial follow-up has shown results similar to the initial data at 18 months, three years, and five years following initial treatment. At five years, median AHI in patients with moderate to severe OSA remained low at 6.2 events per hour. The effectiveness of Inspire therapy was further demonstrated by the results of the randomized controlled therapy withdrawal study, in which patients in the therapy withdrawal group regressed to near-baseline AHI levels while patients in the control group that continued therapy experienced sustained therapeutic benefits.

In addition to the STAR trial, we have established a global real-world patient registry ("ADHERE") to collect data on safety, effectiveness, weekly usage, overall compliance, and satisfaction from patients who have been implanted with an Inspire system for one year after implant. The target enrollment of 5,000 patients was achieved in 2024 and patient follow-up was completed in 2025 with final results pending analysis. For more details on ADHERE, please see the section titled "Clinical Results and Studies—ADHERE Patient Registry" below.

We sell our Inspire system to hospitals and ambulatory surgery centers ("ASCs") in the U.S. and in select countries in Europe through a direct sales organization, and we sell our Inspire system in Japan and Singapore through distributors. As of December 31, 2025, we had 295 sales territories in the U.S. and 21 outside of the U.S. Our direct sales force engages in sales efforts and promotional activities focused on ENT physicians, and sleep centers. In addition, we highlight our compelling clinical data and value proposition to increase awareness and adoption amongst referring physicians. We build upon this top-down approach with strong direct-to-consumer marketing initiatives to create awareness of the benefits of our Inspire system and drive demand through patient empowerment. This outreach helps to educate thousands of patients on our Inspire therapy.

Our U.S. customers are generally reimbursed for the cost of patient treatment by various third-party payors, such as commercial insurance providers and Medicare. We have secured positive coverage policies with many U.S. commercial payors, including all large national commercial insurers, encompassing over 300 million covered lives in the U.S. We are in active discussions with regional commercial insurers to establish additional positive coverage policies, as well as modify existing positive coverage policies to support reimbursement of Inspire therapy. In parallel, a subset of our market access team, which we refer to as our prior authorization team, is focused on assisting patients and physicians in obtaining prior authorization approvals from commercial payors on a case-by-case basis in advance of treatment with our Inspire therapy. In addition, all seven Medicare

Table of Contents

Administrative Contractors ("MACs") provide coverage of Inspire therapy when certain medical necessity criteria are met. We also have a U.S. government contract for patients who are treated by the Veterans Health Administration.

Reimbursement in other countries can often be established through a combination of private (commercial insurance) and public funding sources, or at the hospital level through innovation budgets.

Our Competitive Strengths

We believe the continued growth of our company will be driven by the following competitive strengths:

•First to market with an innovative, closed-loop, minimally invasive solution. We have developed the first FDA-approved neurostimulation technology that provides a safe and effective treatment for patients with moderate to severe OSA who have been confirmed to fail or cannot tolerate PAP treatments, such as CPAP. We received a PMA from the FDA in 2014 for our Inspire therapy. Unlike CPAP, which is limited by low patient compliance primarily due to patient discomfort with the mask or device, our innovative, closed-loop, minimally invasive solution is designed to provide comfort and convenience, resulting in high compliance for patients with moderate to severe OSA. We believe we have a significant first mover advantage and momentum over current and future competitors, as physicians have treated more than 125,000 patients with Inspire therapy.

•Significant body of strong clinical data. We have developed a significant body of clinical data that demonstrates the safety and effectiveness, therapy adherence, and long-term sustained benefits of our Inspire therapy. The benefits of treatment with Inspire therapy have been consistent across seven sponsored and more than 100 independent clinical studies that evaluated several thousand patients and have been highlighted in more than 385 peer-reviewed publications. Data reported in these clinical studies also demonstrated a high level of overall patient satisfaction. We believe this favorable data provides us with a significant competitive advantage and will continue to support increased adoption of our Inspire therapy.

•Holistic and targeted approach to market development and patient engagement. We have established a methodical approach to market development which centers on active engagement across three key stakeholders in the OSA treatment paradigm: physicians, sleep centers, and patients. Our sales force is focused on building long-lasting relationships with ENT physicians and sleep centers as we support physicians through all aspects of a case-from diagnosis to surgical support to patient follow-up. In addition, we are highlighting our compelling clinical data set and value proposition to increase awareness and adoption amongst referring physicians. We build upon this top-down approach with a strong direct-to-consumer marketing initiative that further drives demand through patient empowerment. This outreach helps to educate thousands of patients on our Inspire therapy. Our patient call center, the Advisor Care Program, assists patients with making a connection with a qualified healthcare provider based on their specific needs. We are confident that this holistic approach to engagement across multiple constituents will continue to drive increased awareness of and demand for our Inspire therapy.

•Dedicated team focused on providing market access for patients and providers. We have a refined, efficient approach to advance patients, once identified, to placement of the Inspire system. When required, our dedicated prior authorization team helps patients and providers work with commercial payors to secure prior authorization approvals in advance of initial treatment. In addition, by highlighting the compelling clinical data and the value of our Inspire therapy, the market access team proactively works with payors to establish positive coverage policies where needed and update policies to match the FDA criteria where a policy already exists. This highly effective team has been successful in helping providers and patients to secure reimbursement from hundreds of commercial payors to date, and positive coverage policies from most U.S. commercial payors, including all large national payors.

•Strong research and development capabilities and comprehensive intellectual property portfolio. Our commitment to driving innovation has allowed us to achieve continuous, significant improvements of our Inspire therapy. For example, in 2024, we received approval from the FDA for our Inspire V

neurostimulator, which we began to market for sale in the U.S. in 2025. We have a comprehensive patent portfolio to protect our intellectual property and technology, with rights as of December 31, 2025 to 119 issued U.S. patents, 83 issued foreign patents, 73 pending U.S. patent applications, and 73 pending foreign patent applications that cover aspects of our Inspire system and future product concepts.

Our Strategy

Our goal is to be a global leader in providing clinically proven innovative solutions that improve sleep, quality of life, and health of patients with moderate to severe OSA. We believe the following strategies will play a critical role in achieving this goal and our future growth:

•Foster strong and consistent patient outcomes. Patient outcomes remain the single most important focus for Inspire as we scale our business, and we have a dedicated patient outcomes team furthering this mission. Our Surgical Implant Trainers are tasked with conducting physician trainings and proctoring implants. Care Pathway Specialists develop and promote consistent post-implant care protocols. Our team of Sleep Support Specialists educate and oversee local sleep lab titrations. We believe these teams are critical to ensuring that outcomes continue to improve even as implant volumes increase around the world.

•Improve the customer experience. We believe that by enhancing interconnectivity, simplifying the care pathway, and closely tracking outcomes, we can optimize the customer experience and improve therapy adherence. We have invested in initiatives that we believe will drive higher quality patient flow to reduce time to treatment and increase the capacity of providers to treat and manage more patients. We expect that this will allow patients and health care providers to more efficiently realize the proven benefits of Inspire therapy. We also continue to invest in our SleepSync™ platform, a cloud-based patient management system which allows patients and physicians alike to remotely monitor key compliance and outcomes measures for connected and coordinated care management, thereby optimizing therapy.

•Promote awareness of and reliance on Inspire therapy among patients, ENT physicians, sleep centers, and referring physicians. We believe that many patients who have failed or cannot tolerate CPAP are unaware of our Inspire therapy as a safe and effective alternative treatment for moderate to severe OSA. We intend to continue to promote awareness of our therapy through training and educating ENT physicians, sleep centers, key opinion leaders, and various medical societies on the proven clinical benefits of Inspire therapy. In addition, we intend to continue to publish additional clinical data in various industry and scientific journals and online, and to present at various industry conferences. We also plan to continue building patient awareness through our direct-to-consumer marketing initiatives, which include paid online search, radio, social media, television, and online videos.

•Utilize our dedicated sales and marketing organization to facilitate further adoption of our Inspire therapy. We plan to continue to utilize our talented sales representatives in existing and new markets to help facilitate further adoption and broaden awareness of our Inspire therapy. Our success to date in developing new markets has been primarily due to our ability to identify new regions with high volume medical centers, educate ENT and sleep physicians, help generate steady patient demand, and provide sufficient support staff to our sales representatives. We believe investing in a scalable, efficient direct sales force and continuing the development of our marketing efforts will help us broaden adoption of our Inspire therapy and drive revenue growth.

•Drive an increase in utilization of Inspire therapy at established centers. In addition to continuing to expand our footprint more broadly, we will also focus on building stronger and deeper relationships with customers. We have extensive learnings through our years of pioneering our hypoglossal nerve stimulation therapy, which we intend to use to educate providers on strategies that allow them to improve their identification and potential treatment of moderate-severe OSA patients.

•Invest in research and development to drive innovation and expand indications. Our foundational commitment to driving innovation and improving patient lives fuels our desire for continuous product development. We intend to invest in existing and next generation technologies to further improve our

products and clinical outcomes, optimize patient acceptance and comfort, and broaden the patient population that can benefit from our Inspire therapy. Recent examples of our product innovation include the next generation of the Inspire system and our SleepSync™ programmer. We have a cloud-based patient management system called the SleepSync™ platform which allows physicians to monitor patient compliance and more efficiently coordinate patient care, and the Inspire Sleep app for patients' smartphones. Examples of our efforts to expand our label indications for the Inspire system include obtaining FDA approval in 2023 to offer Inspire therapy to certain pediatric patients with Down syndrome. Additionally in 2023, we received approval from the FDA on an expanded indication which includes an increase on the upper limit of the AHI to 100 events per hour from 65 and raises the body mass index ("BMI") warning in the labeling to 40 from 32.

•Further penetrate and expand into existing and new international markets. We plan to continue to establish and strengthen our presence internationally. Our goal is to further increase sales of our Inspire therapy in existing international markets in Europe, including Germany, France, and the Netherlands, and in the Asia Pacific region, including Japan, Singapore, Hong Kong, and Thailand. We also plan to expand our reach to markets in new regions, such as South Korea. We plan to strategically invest in new markets based on our assessment of market size and opportunity and prospects for compelling reimbursement coding and coverage.

Our Solution for OSA

Overview of Inspire Therapy

Our proprietary Inspire system is the first FDA-approved closed-loop neurostimulation technology that provides a safe and effective treatment for patients with moderate to severe OSA. Both our Inspire IV and Inspire V systems consists of a remote control and the following implantable components (except as otherwise noted):

•in the Inspire IV system, a pressure sensing lead, which detects when the patient is attempting to breathe;

•a neurostimulator, which houses the electronics, battery power for the device, and, as to the Inspire V system, a respiratory sensor; and

•a stimulation lead, which delivers electrical stimulation to the hypoglossal nerve.

A respiratory sensor is used to monitor the patient’s breathing. Our proprietary algorithm tracks breathing patterns and the neurostimulator delivers electrical stimulation at the start of inspiration. This electrical stimulation of the hypoglossal nerve causes a slight forward movement of the back of the tongue that helps maintain an open airway, thereby preventing obstructive events and enabling the patient to inhale freely.

To receive the Inspire system, patients undergo a short outpatient surgical procedure, typically lasting about 30 to 90 minutes, during which the neurostimulator and stimulation lead are implanted, and for the Inspire IV system, a pressure sending lead to monitor the breathing cycle. The Inspire V system incorporates the respiratory sensor inside the neurostimulator so a sensing lead is not required. The procedure is minimally invasive and performed with two small incisions. Patients typically recover quickly and are able to resume normal activities in just a few days. Initial activation of the system occurs 30 days after the implantation. After the initial activation, the patient is instructed to use the therapy each night by turning on their Inspire system before going to sleep using their remote control.

Patients turn their Inspire system on when they plan to go to sleep and turn it off when they awaken. The device has a programmed delay, typically 30 minutes, to allow patients to fall asleep naturally before the device activates. It then monitors the patient’s breathing and delivers mild stimulation to the hypoglossal nerve at the start of the inspiratory phase, causing a slight forward movement at the back of the tongue to maintain an open airway during the inspiratory phase of respiration. The therapy is designed to provide stimulation for each breath to prevent obstructive events.

The effectiveness of Inspire therapy to relieve OSA is objectively measured during a sleep study or polysomnogram. A sleep study records a patient’s breathing, airflow, and blood oxygen levels before and after activating the device. Before activation, the patient experiences multiple periods of interrupted breathing, and oxygen levels repeatedly drop before the patient experiences a transient arousal that allows air intake.

Benefits of Inspire Therapy

We believe our Inspire therapy overcomes many of the limitations of PAP and other current treatments of moderate to severe OSA by providing the following key benefits:

•Safe, effective, and durable treatment. Results from our clinical studies provide compelling safety and efficacy data regarding the clinical benefits of Inspire therapy as many as five years after initial treatment. The results from our STAR trial, a five-year follow-up phase III pivotal trial, demonstrated an approximately 70% reduction in the median AHI from a baseline of 29.3 events per hour to 9.0 events per hour at 12 months following initial treatment. STAR trial follow-up has shown similar results to the initial data at 18 months, three years, and five years. At five years, median AHI remained low at 6.2 events per hour. The results from our ADHERE patient registry also reflect similar median AHI reductions to the STAR trial in a real-world setting.

•Closed-loop system. The Inspire system uses proprietary algorithms to continuously monitor a patient’s breathing and provide electrical stimulation during the inspiratory phase, working with the body’s natural actions to keep the airway open during the breathing cycle.

•Comfortable and convenient therapy resulting in high patient satisfaction. Data reported in the most recent publication of our ongoing ADHERE patient registry demonstrated that patients used Inspire therapy an average of 5.7 hours per night an average of 12 months after initial treatment, with overall patient satisfaction reported to be at 90%.

•Strong patient compliance. Results from our STAR trial demonstrated that 80% of patients continue to use Inspire therapy on a nightly basis five years after initial treatment.

•Similar outcomes and usage as CPAP. Several independent clinical studies demonstrating Inspire therapy has similar improvements in symptoms, and similar nightly usage as CPAP.

•Minimally invasive outpatient procedure. The Inspire system’s implantable components are placed during an approximately 30 to 90-minute outpatient procedure. The procedure is minimally invasive and performed with two small incisions. Patients typically recover quickly and are able to resume normal activities within a few days.

•Long-lasting solution. Our Inspire system uses a battery designed to last approximately 11 years without charging or maintenance.

Commercialization of Inspire Therapy

In the U.S., we obtained PMA for our Inspire system in 2014. Additionally, we received a certificate of conformity for commercialization of our Inspire system in the EU in 2010 which allowed us to affix the European Conformity ("CE") mark on our device. Japan's MLHW approved Inspire therapy in 2018 and Inspire therapy was approved in Singapore and Thailand in 2025.

To commercialize our Inspire system, we focus on physician and patient awareness and adoption of our Inspire therapy. To achieve this, our commercialization strategy primarily consists of our direct sales force engaging in sales efforts and promotional activities focused on ENT physicians and sleep centers and highlighting our compelling clinical data and value proposition. Our direct sales force utilizes strong direct-to-consumer marketing initiatives to create awareness of the benefits of our Inspire system. We intend to continue to make significant investments in our direct-to-consumer marketing efforts in existing and new markets throughout the U.S. and Europe.

Table of Contents

In Singapore, Hong Kong, and Thailand, our commercialization approach is through exclusive distribution partners, who are responsible for local sales and promotional activities focused on ENT physicians, sleep centers, and community awareness. We work closely with the distributors to ensure a globally consistent approach and effective employee and customer training are in place.

In addition, a significant part of our commercialization effort consists of supporting our customers through the reimbursement process. Most commercial U.S. insurers now cover Inspire therapy. For those commercial payors that do not have a positive policy, Inspire provides assistance to patients and physicians on a case-by-case basis to help support appropriate prior authorization approvals in advance of treatment. Medicare also has positive coverage for all states, and we have a U.S. government contract for patients who are treated by the Veterans Health Administration.

Treatment with Inspire Therapy

Patient Selection

Inspire therapy is indicated for patients with moderate to severe OSA (AHI of 15 to 100) who do not have significant central sleep apnea and do not have a complete concentric collapse of the airway at the soft palate level. Patients undergo a drug-induced sleep endoscopy ("DISE") performed by an ENT surgeon in order to confirm that they satisfy this anatomical requirement. In addition, patients in the U.S. and Japan must have been confirmed to fail or be unable to tolerate PAP treatments, such as CPAP, and be 18 years of age or older, though there are no similar requirements for patients in Europe. Patients who fail PAP are those that are not able to eliminate moderate to severe OSA despite PAP usage. Patients who cannot tolerate PAP treatments are those who either are unable to use PAP more than five nights per week for at least four hours per night, or who are unwilling to use PAP treatment.

Implantation

The Inspire system is implanted under general anesthesia through two small incisions. One incision is under the lower jaw, where the stimulation lead is attached around a distal branch of the hypoglossal nerve that is responsible for forward movement of the tongue. A second incision in the upper right chest below the clavicle is used to implant the neurostimulator, which houses all the electronics and battery power for the device, and, for the Inspire IV system, a pressure sensing lead to monitor the breathing cycle. The Inspire V system incorporates the respiratory sensor inside the neurostimulator so a sensing lead is not required. The functionality of the Inspire system is tested in the operating room to verify proper placement of the lead or leads. The Inspire system is powered by an internal battery that is designed to last approximately 11 years without needing to be recharged. After this time, the neurostimulator is replaced during a simple outpatient procedure.

The implantation procedure is performed in an outpatient setting and surgery is completed in approximately 30 to 90 minutes. Patients may experience mild discomfort and swelling at the incision sites for a few days that is usually managed with over-the-counter pain medications. Patients can return home and resume a normal diet shortly after completion of the procedure and resume most daily activities within a few days. The only restriction on their activity is to avoid strenuous activities until the incisions have had time to heal.

Activation

Patients are allowed to heal for a month before the Inspire system is activated through a wireless connection to the device in the clinician’s office. The initial activation is performed by the clinician using the SleepSync™ programmer that is able to turn the system on as well as change various parameters such as the strength, timing, and duration of the stimulation pulse, the stimulating electrode configuration, and the sensitivity of respiration detection. With the exception of pulse strength, the factory default settings are used in the majority of patients. The pulse strength is initially adjusted to the lowest level required to move the tongue forward.

Patients receive a remote control that they use to turn their Inspire system on when they plan to go to sleep and to turn it off when they awaken. The device has a programmed delay, typically 30 minutes, to allow patients to fall asleep naturally before the device activates. It then delivers mild stimulation to the hypoglossal nerve, causing the

12

Table of Contents

tongue to move as the patient is inhaling. The remote enables patients to adjust the strength of the stimulation to optimize their therapy and comfort. The range of control given to patients is limited to avoid setting the strength of the stimulation to an ineffective or excessively high level. Patients also have the ability to temporarily pause therapy if they awaken during the night.

Clinical Results and Studies

A significant body of published clinical evidence, which includes seven sponsored and more than 100 independent clinical studies that evaluated several thousand patients, supports the safety and effectiveness of Inspire therapy. The results of the STAR trial, our phase III pivotal clinical trial that served as the basis for the FDA approval of our PMA application, were published in the New England Journal of Medicine, and the results of additional clinical studies have been published in more than 385 peer-reviewed publications.

ADHERE Patient Registry

We have established a global patient registry, which we refer to as our ADHERE patient registry, to collect data on safety, effectiveness, weekly usage, overall compliance, and satisfaction from patients who have been implanted with an Inspire system for one year after Inspire implant. The target enrollment of 5,000 patients was achieved in 2024. The most recent analysis, published in the Journal of Clinical Sleep Medicine in 2022 on 1,963 patients enrolled, showed that patients used Inspire therapy an average of 5.7 hours per night when measured an average of 12 months after implantation. Median AHI was reduced from 33.0 events per hour to 10.2 events per hour and median ESS score improved from 11 to 6 over the same period. Overall satisfaction with Inspire therapy was reported by patients to be 90%, with 92% of patients reporting that they would choose the procedure again. In addition, 91% of patients reported a better experience than CPAP. This same study demonstrated comparable outcomes across five disease severity groups.

Select Recent Clinical Results and Studies

Meta-analysis showed many patients with body mass index greater than 32 kg/m2 benefit from Inspire therapy

Dr. Coleton Evans and colleagues published a meta-analysis and systematic review of studies that reported on adult patients who received Inspire therapy for OSA, and that also included analysis on patients above and below BMI of 32 kg/m2 (a common cutoff for insurance approval). They identified seven studies encompassing 1,572 patients to include in their systematic review, of which four studies (1,017 patients) were included in the meta-analysis. The pooled odds ratio for treatment success for BMI ≥ 32 kg/m2 vs BMI 32 kg/m2 was 0.87 (95% confidence interval 0.68 - 1.11). This suggests no statistically significant difference in surgical success between the BMI groups, and that many patients with BMI ≥ 32 kg/m2 achieved clinically meaningful objective and subjective improvements with Inspire therapy.

Inspire therapy has been shown to effectively treat supine and non-supine obstructive sleep apnea

Dr. Lidice Hernandez and colleagues published a retrospective observational study of 27 patients who had sufficient positional data which showed reductions in both supine and non-supine AHI. The authors concluded that their findings support the clinical utility of Inspire therapy in both positional dependent and non-positional dependent OSA.

Long term follow-up of Inspire therapy in adolescents with Down syndrome

Dr. Danielle Larrow and colleagues published long term follow up data for 33 patients with Down syndrome and OSA. These patients, implanted as adolescents, were part of the 42 patient cohort whose outcomes (published in 2022) supported Inspire’s expanded indications for teenagers with Down syndrome. Follow up time averaged four years with a standard deviation of 1.9 years, at which point 29/33 (88%) demonstrated a 50% reduction in AHI, with an average decrease of 60% across all 33 patients. These data show that adolescents with Down syndrome showed durable improvement in objective measures of their OSA.

Inspire has the potential to improve neurocognitive and psychosocial outcomes

Dr. Arman Saeedi and colleagues published Patient Reported Outcome Measurement Information System ("PROMIS") survey results from a cohort of 42 patients (all aged over 50 years) who had Inspire implanted to treat their OSA. PROMIS surveys are validated and psychometrically sound measures of life domains developed by the U.S. Department of Health and Human Services. This cohort showed a reduction from an average AHI of 31 to an average of 14 while using Inspire therapy for an average of seven hours per night. Their PROMIS scores showed significant post-treatment improvements in sleep impairment, cognitive function, depression, anxiety, anger, and loneliness.

Sales and Marketing

We have established a methodical approach to market development which centers on active engagement across three key stakeholders in the OSA treatment paradigm: patients, physicians, and sleep centers.

We sell our Inspire system through a direct sales force that primarily targets ENT physicians and sleep centers in the U.S., Europe, and Japan, and through distributors in Singapore, Hong Kong, and Thailand. The implant procedure for our Inspire therapy is typically performed by an ENT physician or in some cases by a neurosurgeon. We also focus on sleep centers because they diagnose and manage large volumes of patients with sleep apnea and are often an important referral base for ENT physicians. In addition, because OSA is sometimes diagnosed during other procedures, we have developed programs to help educate general practitioners and specialists in other fields, such as cardiovascular surgeons, electrophysiologists, and dentists, regarding our Inspire therapy.

We continue to make significant investments in our sales and marketing organization by increasing the number of sales support personnel. In 2025, we began optimizing our sales model through targeted territory consolidation and increased field clinical representatives ("FCRs"), consistent with our strategy of a ratio of 1:1 territory manager to FCR. This enables territory managers to focus on therapy awareness, surgeon recruiting and training, and driving the adoption of Inspire therapy, while FCRs provide technical and clinical expertise as well as educational and field support. As of December 31, 2025, we had 295 U.S. sales territories and 275 U.S. FCRs, as compared with 335 U.S. sales territories and 230 U.S. FCRs as of December 31, 2024. Outside of the U.S., we had 21 and 25 sales territories at December 31, 2025 and 2024, respectively.

We seek to recruit sales representatives with strong sales backgrounds, direct experience developing markets with new technologies, and core knowledge of medical device coding, reimbursement, and the prior authorization process. In certain Asian markets, we rely on our distribution partners for local sales and promotional activities.

Direct patient education remains a core growth strategy for us. Our marketing investments focus on efficiently reaching qualified patients across high‑impact channels and the InspireSleep.com website, where they can better understand OSA, learn about Inspire therapy as a proven option for OSA treatment, and get connected with trained providers in their area. Through our tested direct-to-patient messaging, we aim to bring advanced medical

14

Table of Contents

topics to an approachable level for patient consumers, We leverage more than a decade of real‑world outcomes and patient stories to demonstrate therapy effectiveness and benefits that can only be achieved by a therapy that has been shown to be used consistently by patients night after night, accelerating patient interest and activation. These efforts continue to support strong awareness, engagement, and conversion.

We continue to refine our communication to health care professionals to reinforce Inspire’s value proposition and support ongoing clinical adoption. The Inspire app remains an important tool for patient education and provider insight through its integration with SleepSync™. Going forward, we expect to further optimize our targeting, strengthen our brand platform across all audiences, and maintain a consistent level of marketing investment.

We operate a call center, known as the Inspire Advisor Care Program, which assists patients in connecting with a qualified healthcare provider based on their specific needs. The program also uses a digital scheduling capability that streamlines and simplifies patient access to care. We plan to continue enhancing and expanding this scheduling capability throughout 2026.

Commercial Activities Outside of the U.S.

Our general practice is to limit commercial investments in countries until such time as there is a determined reimbursement pathway. We have 21 sales territories in Europe and Japan, and we sell our products through distributors in Singapore, Hong Kong, and Thailand. We provide consistent training in geographies outside of the U.S. as is conducted in the U.S. and have established a support team in Europe and Japan for patient outreach and education, implant support, and device programming. In areas in which we use distributors, we assist our distribution partners with patient outreach and education initiatives, as well as with remote implant support and post-implant titration. We expect to continue to scale our commercial activities in Europe as we continue to develop country-wide reimbursement in additional markets. We are currently pursuing regulatory approval in Korea.

Third-Party Reimbursement

Our market access team is responsible for all of our reimbursement processes and initiatives. Our team of professionals are focused on all key aspects of reimbursement, which include prior authorization, coding, coverage, and payment.

Coding and Payment

In the U.S., we sell our products to hospitals and ASCs. These customers in turn bill various third-party payors, such as commercial payors and Medicare, for the cost required to treat each patient. These costs and the related reimbursements for aspects of the Inspire IV and Inspire V therapies can vary and are not the same across commercial payors and government payors. In addition, there are currently, and can be in the future, different codes, modifiers (where applicable), and processes (such as prior authorization) used for our Inspire therapy given the variety of payors. Our customers and providers also have many different models that may result in coding and reimbursement decisions having more or less impact on our revenues and results of operations (for example, fee-for-service and value-based care models).

Third-party payors require physicians and hospitals 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. Physician reimbursement under Medicare is based on a defined fee schedule, the Medicare Physician Fee Schedule, through which payment amounts are determined by the relative values of the professional service rendered. Medicare provides reimbursement to our hospital and ASC customers under the outpatient prospective payment system and ASC prospective payment system, respectively, which provide bundled amounts generally intended to reimburse the hospital or ASC for device and facility costs related to procedures performed in the outpatient setting.

Reimbursement rates from commercial payors vary depending on the procedure performed, the commercial payor, contract terms, and other factors.

Commercial Payor and Government Program Coverage

A core pillar of our reimbursement strategy involves broadening our third-party payor coverage when possible. We continue to have active discussions with commercial payors to establish new and modify existing positive coverage policies by highlighting our compelling and robust clinical data, increased patient demand, and support from leading medical societies and key opinion leaders. We have been successful in helping our customers and patients pursue prior authorization approvals from most commercial payors for the Inspire device and procedure. Historically, commercial payors cover approximately 45% to 50% of Inspire implants in the U.S. Medicare Advantage, which is also managed by the private commercial health care plans, covers approximately 15% to 20% of Inspire implants. We estimate that the majority of patients who meet the FDA-approved indication for Inspire therapy are covered by commercial insurance companies and we have secured coverage policies with all major national commercial payors.

In terms of government program coverage, all seven MACs provide coverage of Inspire therapy when certain coverage criteria are met. Fee-for-service Medicare beneficiaries have historically accounted for approximately 25% to 30% of all Inspire system implantations in the U.S. In addition, we have a contract with the U.S. government that covers implantations of our Inspire system performed in Veterans Affairs and military hospitals, which account for approximately 5% to 10% of all Inspire system implantations historically in the U.S.

Prior Authorization Approval Process

A second pillar of our reimbursement strategy includes leveraging our prior authorization team to assist patients and physicians in obtaining appropriate prior authorization approvals from commercial payors in advance of treatment. We believe our prior authorization team is highly effective in working with patients and physicians to support prior authorizations for our Inspire system, including assisting with the appeals process in the event of a denial. Our customers have received thousands of prior authorization approvals from all of the largest commercial payors in the U.S. We believe we will continue to benefit from this efficient prior authorization process.

Reimbursement Outside of the U.S.

Outside the U.S., reimbursement levels vary by country and by region within some countries. Reimbursement is obtained from a variety of sources, including government-sponsored and private health insurance plans, and combinations of both. Some countries require additional clinical data before granting or expanding coverage and reimbursement for our products. In general, obtaining broad-based reimbursement and adequate payment for new technologies is more difficult in these markets than in the U.S. Some countries require new medical technologies to not only be safe and effective, but also to be able to demonstrate clinical benefits that outweigh the costs when compared to the standard of care. As in the U.S., reimbursement decisions can change, resulting in the elimination or reduction of reimbursement payments, which could adversely affect our financial results and our ability to invest in and grow our business.

We currently have country wide reimbursement in Germany, the Netherlands, Switzerland, France, Belgium, the United Kingdom, and Japan. We continue to pursue permanent reimbursement in target markets across the Asia Pacific and Europe, including Spain and the Nordic region.

Research and Development

Product Evolution and Next Generation Products

The first Inspire device was developed by Medtronic Inc. (now Medtronic Public Limited Company), or Medtronic, in the early 1990s as a radio frequency controlled device that required an external apparatus to deliver electrical stimulation to the hypoglossal nerve. The first fully implantable, respiration-sensing, closed-loop Inspire system was developed shortly thereafter. Based on the initial clinical trial results, which were published in 2001, Medtronic began developing what became known as our Inspire II system, introducing a new, more durable stimulation lead and lower-power neurostimulator, and relocating the respiratory sensing lead to between the intercostal muscle layers.

16

Table of Contents

After our 2007 inception and contemporaneous spin-off of the Inspire business from Medtronic, our primary focus was to requalify the Inspire II system and resume clinical trial activity. We completed a phase I feasibility trial along with a phase II dosing or patient selection trial in 2009. In 2011, we began our phase III pivotal STAR trial. The STAR trial was completed and published in the New England Journal of Medicine in 2014 and we received PMA in 2014. Additionally, the device was CE marked for commercialization in the EU in 2010.

We continue to invest in advancing our Inspire system with the goal of providing patients more effective and less invasive therapy for OSA. In 2017, we released the Inspire IV neurostimulator, which is 40% smaller than the previous version while maintaining approximately 11 years of battery life. The Inspire IV device was launched in the U.S. in 2017, and in Europe in 2018.

Our latest generation of the Inspire neurostimulator, Inspire V, was approved by the FDA in 2024, and our updated SleepSync™ programmer was approved by the FDA in 2023. Our Bluetooth®-enabled patient remote control was approved by the FDA in 2021. We have launched a cloud-based patient management system called the SleepSync™ platform, which allows physicians to monitor patient compliance and more efficiently coordinate patient care. In 2020, we launched the Inspire Sleep app for patients' smartphones. The app serves as an educational tool and, since 2022, interfaces with the patient remote and SleepSync™ platform, which allows physicians to monitor patient compliance and more efficiently coordinate patient care. We continue to enhance the functionality of this app as part of our overall digital platform development.

The SleepSync™ platform and our app are initial steps in establishing interconnectivity between the patient and their healthcare provider with a long-term plan to improve outcomes by tracking patient activity and adherence, and monitoring for any issues with device use.

Additional Indications

We have sought and continue to seek to expand the approved indications for our Inspire therapy. For instance, in 2023, we received FDA authorization to provide Inspire therapy to the pediatric population with Down syndrome. Also in 2023, the FDA approved an indication expansion to increase the upper limit of AHI to up to 100 events per hour from the original 65 events per hour, and to raise the BMI warning for patients with a BMI of up to 40 from the previous limit of 32.

Our research and development team focuses on our products currently under development, including our clinical studies involving efforts to improve patient selection, expand indications, and simplify patient management, as well as feasibility studies in which we are evaluating new ways to deliver neuromodulation for OSA therapy and different design configurations to enhance product functionality for future generations of the Inspire system. One example is our PREDICTOR study, the objective of which is to determine whether certain patient and/or patient anatomical characteristics, such as pharyngeal width (inside of the mouth), are predictors of the absence of complete concentric collapse at the soft palate, which could help eliminate the need for DISE in some Inspire patients who are less likely to have complete concentric collapse. Enrollment of 600 patients in the study was completed in early 2024. The results of this study suggest that approximately 10% of patients with OSA have complete concentric collapse ("CCC"). In general, the patients with CCC were younger, had a higher BMI, a larger neck circumference, and a higher baseline AHI. Patients with CCC were also more likely to be male as compared to the non-CCC patients. A CART model, combining BMI and neck circumference, was the most accurate prediction of non-CCC, indicating that patients with a BMI of less than 28 or BMI of less than 32 with a neck circumference of less than 17.7 inches were unlikely to have CCC. We believe these results suggest that these patients may not need to undergo DISE screening for CCC.

Competition

Our industry is subject to rapid change from the introduction of new products, technologies, pharmaceuticals, and various activities of industry participants. We are positioned as a second-line therapy in the OSA treatment market for patients with moderate to severe OSA. In the U.S., Inspire therapy is only indicated for patients who have been confirmed to fail or cannot tolerate PAP treatments, such as CPAP.

17

Table of Contents

While we are second-line to PAP therapies, there remains some competition with PAP therapies as sleep physicians often remain committed to prescribing PAP despite poor patient adherence to therapy. Our specific PAP-related competitors include ResMed Inc., Philips BV, Fisher & Paykel Healthcare Corporation Limited, and various regional and new-entrant manufacturers. Currently, we have only one direct neurostimulation competitor in the US for the treatment of OSA, Nyxoah SA and its subsidiary Nyxoah, Inc. ("Nyxoah"). Nyxoah provides an open-loop, bilateral stimulation system that does not include a respiratory sensor. Indications for this device differ partially from those for Inspire. In 2025, LivaNova PLC ("LivaNova") also submitted an application to the FDA to market a hypoglossal nerve stimulation device in the U.S. Additionally, we compete with various other second-line therapies to treat OSA, including invasive surgical treatment options such as uvulopalatopharyngoplasty ("UPPP"), maxillomandibular advancement ("MMA"), robotic tongue reduction surgery, and, to a lesser extent, oral appliances, which are primarily used in the treatment of mild to moderate OSA.

Oral appliances and some other surgical treatments are better known to ENT physicians, sleep centers and the other physicians on whom we rely for referrals, but we believe physician awareness of our Inspire therapy is increasing.

Outside of the U.S., in addition to the Inspire therapy, other second-line therapy alternatives that compete with CPAP and PAP include therapies marketed by Nyxoah and LivaNova. Nyxoah markets their open-loop bilateral hypoglossal nerve stimulation device, described above in certain countries, and LivaNova also markets an open-loop neurostimulation device outside the U.S.

Additionally, a drug candidate produced by Apnimed is undergoing a Phase 3 clinical trial to assess the viability of its pharmaceutical to treat OSA. In December 2024, the GLP-1 drug Zepbound (tirzepatide), was FDA approved for treatment of OSA in patients with obesity and moderate to severe OSA. We believe other emerging businesses are in the early stages of developing alternative OSA treatment therapies or early-stage pharmaceutical approaches.

We believe that the primary competitive factors in the OSA treatment market are:

•company, product, and brand recognition;

•product safety, efficacy, reliability, and durability;

•quality and volume of clinical data;

•effective marketing to and education of patients, physicians, and sleep centers;

•product ease of use and patient comfort;

•sales force experience and access;

•product support and service;

•technological innovation, product enhancements, and speed of innovation;

•pricing and revenue strategies;

•procedure costs to patients;

•effectiveness of reimbursement teams and strategies; and

•dedicated practice development and clinical training teams.

We also compete with other medical technology companies to recruit and retain qualified personnel.

Intellectual Property

We rely on a combination of patent, copyright, trademark and trade secret laws, and confidentiality and invention assignment agreements to protect our intellectual property rights. As of December 31, 2025, we had rights to 119 issued U.S. patents, which will expire between 2029 and 2043 assuming all required fees are paid, 73 pending U.S. patent applications, 83 issued foreign patents, and 73 pending foreign patent applications. Our patents cover aspects of our current Inspire system and future product concepts. Some of the issued foreign patents and pending foreign patent applications preserve an opportunity to pursue patent rights in multiple countries.

We are currently a party to multiple adversarial proceedings with Nyxoah regarding our patent portfolio. For additional information, see Note 11, Commitments and Contingencies to the consolidated financial statements included elsewhere in this Form 10-K.

As of December 31, 2025, we had 178 pending and registered trademark filings worldwide, some of which may apply to multiple countries.

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.

Our pending patent applications may not result in issued patents, and we cannot ensure that any current or subsequently issued patents will adequately protect our products or provide us with any competitive advantage. . See Part I, "Item 1A. Risk Factors — Risks Related to Intellectual Property Matters” for additional information regarding these and other risks related to our intellectual property portfolio and their potential effect on us.

License Agreement with Medtronic

In 2007, we entered into an assignment and license agreement with Medtronic ("the Assignment and License Agreement") pursuant to which Medtronic assigned certain patents and trademarks to us and granted to us a worldwide, royalty-free license to certain other patents and technical information to make, use, import and sell products, and to practice methods in the field of electrical stimulation of the upper airway for the treatment of OSA ("the Field"). We share co-exclusive rights with Medtronic under this license; however, Medtronic may not exercise its rights unless we make an assignment for the benefit of our creditors, file or have filed against us a bankruptcy petition or go into receivership. We also granted to Medtronic certain worldwide, royalty-free, exclusive licenses to the patents Medtronic assigned to us, as well as other intellectual property (including but not limited to Technical Information (as defined in the Assignment and License Agreement)) that applies to a device and methods with certain specifications for use in the Field, to make, use, import and sell products, and to practice methods outside of the Field. The licenses granted are perpetual and irrevocable.

Manufacturing and Supply

We rely on third-party suppliers to manufacture our Inspire system and its components. Outsourcing manufacturing reduces our need for capital investment and reduces operational expense. Additionally, outsourcing provides expertise and capacity necessary to scale up or down based on demand for our Inspire system. We select our suppliers so that our Inspire system and its components are safe and effective, adhere to all applicable regulations, are of the highest quality, and meet our supply needs. We employ a rigorous supplier assessment, qualification, and selection process with the goal of selecting and retaining suppliers that meet the requirements of the FDA and the International Organization for Standardization and quality standards based on our internal policies and procedures. Our quality assurance process seeks to monitor and maintain supplier performance through qualification and periodic supplier reviews and audits.

Certain components used in our Inspire system are supplied by single-source suppliers. Our suppliers manufacture the components they produce for us and test our components and devices to our specifications. We intend to maintain sufficient levels of inventory to enable us to continue our operations while we obtain another

19

Table of Contents

supplier in the event that one or more of our single-source suppliers were to encounter a delay in supply or end supply.

We have experienced supply disruptions that began during the COVID-19 pandemic, but to date we have managed to avoid major delays in implant procedures due to those issues. During the third quarter of 2023 and into the first half of 2024, we experienced an inventory supply issue related to our polyurethane-based stimulation leads, one component of the Inspire system currently used only in the European market, as a result of delays in the EU MDR certification process. This issue impacted our revenue in those periods, however, the issue has been resolved. See Part II, Item 7 “Management’s Discussion and Analysis of Financial Condition and Results of Operations — Overview” for additional information.

Our products are shipped directly to our U.S. customers and to our distributors on a purchase order basis, primarily by a third-party vendor with facilities in California and North Carolina, although we do ship some products from our facility in Minnesota. Warehousing and shipping operations for our European customers are handled by a third-party vendor with a facility located in the Netherlands, and warehousing and shipping operations for our Japanese customers are handled by a third-party with a facility in Japan. Customers do not have the right to return a non-defective product, nor do we place product on consignment. Our sales representatives do not maintain trunk stock.

Government Regulation

As a global technology company, we are subject to significant government regulation, compliance requirements, fees and costs, both in the U.S. and abroad. These regulatory requirements subject our products and our business to numerous risks that are specifically discussed within Part I, Item 1A, “Risk Factors” within this Annual Report on Form 10-K.

Our products and our operations are subject to extensive regulation by the FDA and other federal and state authorities in the U.S., as well as comparable authorities in the European Economic Area ("EEA"), Japan, and in Thailand, South Korea and Australia (where our products are approved for sale but where we have not yet commercialized them). In the U.S., our products are subject to regulation as medical devices under the Federal Food, Drug, and Cosmetic Act ("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 help 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 studies 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 studies and to obtain marketing authorization, approval or certification of our products under the comparable regulatory authorities of countries outside of the U.S. or notified bodies before we can commercialize our products in those countries. The approval/certification process varies from country to country and the time may be longer or shorter than that required for FDA clearance or approval.

We expect additional state, federal, and foreign healthcare reform measures to be adopted in the future, which may adversely affect our business. For additional information, see Part I, Item 1A, “Risk Factors - Current and future healthcare reform legislation or regulation may increase the difficulty and cost for us to commercialize our products and could harm our business, financial condition and results of operations.”

FDA Premarket Clearance and Approval Requirements

Unless an exemption applies, each medical device commercially distributed in the U.S. requires either FDA clearance of a 510(k) premarket notification or 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

20

Table of Contents

includes devices with the lowest risk to the 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 FDA's Quality Management System Regulation ("QMSR"), 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. 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 prior to May 28, 1976, the date upon which the Medical Device Amendments of 1976 were enacted, or another legally marketed device that was cleared through the 510(k) process.

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.

Our currently marketed Inspire products are Class III devices which have received PMA.

PMA Pathway

In a PMA, the manufacturer must demonstrate that the device is safe and effective, and the PMA must be supported by extensive data, including data from preclinical studies and human clinical studies. 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. If the FDA accepts a submitted PMA application for substantive review, it has 180 days under the FDCA to complete its review, although in practice, the FDA’s review often takes significantly longer. In addition, the FDA will generally conduct a preapproval inspection of the applicant or its third-party manufacturers’ or suppliers’ manufacturing facility or facilities to ensure compliance with the QMSR.

The FDA will approve the device for commercial distribution if it determines that the data and information in the PMA 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 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 PMA or requirements to conduct additional clinical studies post-approval. The FDA may condition PMA on some form of post-market surveillance when deemed necessary to protect 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 PMA supplement. PMA supplements often require submission of the same type of information as a PMA, except that the supplement is limited to information needed to support any changes from the device covered by the original PMA 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, 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 are not applicable for the change in demonstrating a reasonable assurance of safety and effectiveness.

21

Table of Contents

Clinical Studies

Clinical studies are almost always required to support a PMA submission and may be required to support certain PMA supplements. All clinical investigations of investigational devices to determine safety and effectiveness must be conducted in accordance with the FDA’s investigational device exemption ("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 studies. 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. The IDE will automatically become effective 30 days after receipt by the FDA unless the FDA notifies the company that the investigation may not begin. An IDE supplement must also 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.

If an IDE application is approved by the FDA and one or more institutional review boards ("IRBs"), human clinical studies 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 study after obtaining approval for the study 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.

During a study, the sponsor is required to comply with the applicable FDA requirements, including, for example, study 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. Additionally, after a study begins, the sponsor, the FDA or the IRB could suspend or terminate a clinical study at any time for various reasons, including a belief that the risks to study subjects outweigh the anticipated benefits.

Expedited Development and Review Programs

Following passage of the 21st Century Cures Act, the FDA implemented the Breakthrough Devices Program, which is a voluntary program offered to manufacturers of certain medical devices and device-led combination products, including ours, that may provide for more effective treatment or diagnosis of life-threatening or irreversibly debilitating diseases or conditions. The goal of the program is to provide patients and health care providers with more timely access to qualifying devices by expediting their development, assessment and review, while preserving the statutory standards for FDA marketing authorization. The program is available to medical devices that meet certain eligibility criteria, including that the device provides more effective treatment or diagnosis of life-threatening or irreversibly debilitating diseases or conditions, and that the device meets one of the following criteria: (i) the device represents a breakthrough technology, (ii) no approved or cleared alternatives exist, (iii) the device offers significant advantages over existing approved or cleared alternatives, or (iv) the availability of the device is in the best interest of patients. Breakthrough Device designation provides certain benefits to device developers, including more interactive and timely communications with FDA staff, use of post-market data collection, when scientifically appropriate, to facilitate expedited and efficient development and review of the device, opportunities for efficient and flexible clinical study design, and prioritized review of premarket submissions.

Post-market Regulation

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

•establishment registration and device listing with the FDA;

22

Table of Contents

•QMSR requirements, which require manufacturers, including third-party manufacturers, to follow stringent design, testing, control, documentation, and other quality assurance procedures during all aspects of the design and manufacturing process;

•labeling and marketing regulations, which require that promotion is truthful, not misleading, fairly balanced, provide adequate directions for use, and that all claims are substantiated, and also prohibit the promotion of products for unapproved or “off-label” uses and impose other restrictions on labeling; FDA guidance on off-label dissemination of information and responding to unsolicited requests for information;

•clearance or approval of product modifications to 510(k)-cleared devices that could significantly affect safety or effectiveness or that would constitute a major change in intended use of one of our cleared devices, or approval of a supplement for certain modifications to PMA devices;

•medical device reporting regulations, which require that a manufacturer report to the FDA if a device it markets may have caused or contributed to a death or serious injury, or has malfunctioned and the device or a similar device that it markets would be likely to cause or contribute to a death or serious injury, if the malfunction were to recur;

•correction, removal, and recall reporting regulations, which require that manufacturers report to the FDA field corrections and product recalls or removals if undertaken to reduce a risk to health posed by the device or to remedy a violation of the FDCA that may present a risk to health;

•complying with the laws and regulations requiring Unique Device Identifiers (UDI) on devices and also requiring the submission of certain information about each device to the FDA’s Global Unique Device Identification Database (GUDID);

•the FDA’s recall authority, whereby the agency can order device manufacturers to recall from the market a product that is in violation of governing laws and regulations; and

•post-market surveillance activities and regulations, which apply when deemed by the FDA to be necessary to protect public health or to provide additional safety and effectiveness data for the device.

Our manufacturing processes are required to comply with the applicable portions of the QMSR, which currently cover the methods and the facilities, 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 QMSR also requires, among other things, maintenance of a medical device master 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 QMSR 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.

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:

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

•recalls, withdrawals, or administrative detention or seizure of our products;

•operating restrictions or partial suspension or total shutdown of production;

23

Table of Contents

•refusing or delaying requests for 510(k) marketing clearance or PMAs of new products or modified products;

•withdrawing 510(k) clearances or PMAs that have already been granted;

•refusal to grant export or import approvals for our products; or

•criminal prosecution.

Foreign Regulation

In order for us to market our products in countries outside the U.S., we must obtain regulatory approvals or certifications and comply with extensive product and quality system regulations in other countries. These regulations, including the requirements for approvals, clearance or certifications and the time required for regulatory review, vary from country to country. Some countries have regulatory review processes that are substantially longer than U.S. processes. Failure to obtain regulatory approval or certification in a timely manner and meet all of the local requirements including language and specific safety standards in any foreign country in which we plan to market our products could prevent us from marketing products in such countries or subject us to sanctions and fines.

Regulation of Medical Devices in the European Union

The EU has adopted specific directives and regulations regulating the design, manufacture, clinical investigation, conformity assessment, labeling and adverse event reporting for medical devices.

Until May 25, 2021, medical devices were regulated by Council Directive 93/42/EEC (the “EU Medical Devices Directive”), and Directive 90/385/EEC (“AIMDD”) which have been repealed and replaced by the EU Medical Devices Regulation. The validity of our certificates, initially granted under the AIMDD, has been extended by virtue of the amendment to the EU Medical Devices Regulation, specifically Regulation (EU) 2023/607 as regards the transitional provisions for certain medical devices. Surveillance of the initial AIMDD certificate has been transferred from our original notified body BSI, to our current notified body DEKRA. This makes it possible for us to sell off inventory that is CE marked and labeled under the AIMDD. The Inspire system is also now CE marked under the EU Medical Devices Regulation. Unlike the EU Medical Devices Directive and Active Implantable Medical Device Directive, the EU Medical Devices Regulation is directly applicable in EU member states without the need for member states to implement into national law.

In the EU, there is currently no premarket government review of medical devices. However, all medical devices placed on the EU market must meet general safety and performance requirements, including the requirement that a medical device must be designed and manufactured in such a way that, during normal conditions of use, it is suitable for its intended purpose. Medical devices must be safe and effective and must not compromise the clinical condition or safety of patients, or the safety and health of users and – where applicable – other persons, provided that any risks which may be associated with their use constitute acceptable risks when weighed against the benefits to the patient and are compatible with a high level of protection of health and safety, taking into account the generally acknowledged state of the art.

Compliance with the general safety and performance requirements is a prerequisite for European conformity marking (“CE mark”) without which medical devices cannot be marketed or sold in the EU. To demonstrate compliance with the general safety and performance requirements medical device manufacturers must undergo a conformity assessment procedure, which varies according to the type of medical device and its (risk) classification. Except for low-risk medical devices (Class I), where the manufacturer can self-assess the conformity of its products with the general safety and performance requirements (except for any parts which relate to sterility, metrology or reuse aspects), a conformity assessment procedure requires the intervention of a notified body. Notified bodies are independent organizations designated by EU member states to assess the conformity of devices before being placed on the market. A notified body would typically audit and examine a product’s technical dossiers and the manufacturer’s quality system. If satisfied that the relevant product conforms to the relevant general safety and performance 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 EU.

Throughout the term of the certificate of conformity, the manufacturer will be subject to periodic surveillance audits to verify continued compliance with the applicable requirements. In particular, there will be a new audit by the notified body before it will renew the relevant certificate(s).

The EU Medical Devices Regulation requires that before placing a device, other than a custom-made device, on the market, manufacturers (as well as other economic operators such as authorized representatives and importers) must register by submitting identification information to the electronic system (Eudamed), unless they have already registered. The information to be submitted by manufacturers (and authorized representatives) also includes the name, address and contact details of the person or persons responsible for regulatory compliance. The new Regulation also requires that before placing a device, other than a custom-made device, on the market, manufacturers must assign a unique identifier to the device and provide it along with other core data to the unique device identifier (“UDI”) database. These new requirements aim at ensuring better identification and traceability of the devices. Each device – and as applicable, each package – will have a UDI composed of two parts: a device identifier (“UDI-DI”) specific to a device, and a production identifier (“UDI-PI”) to identify the unit producing the device. Manufacturers are also notably responsible for entering the necessary data on Eudamed, which includes the UDI database, and for keeping it up to date. The obligations for registration in EUDAMED will become applicable on May 28, 2026 (for the first four modules related to (i) economic operators, (ii) UDI/devices registrations, (iii) NB/Certificates, and (iv) market surveillance). Until the effective date, respectively until Eudamed is fully functional with regard to other modules, the corresponding provisions of the EU Medical Devices Directive and the AIMDD, respectively national provisions, continue to apply for the purpose of meeting the obligations laid down in the provisions regarding exchange of information, including, and in particular, information regarding registration of devices and economic operators.

All manufacturers placing medical devices into the market in the EU must comply with the EU medical device vigilance system. Under this system, serious incidents and Field Safety Corrective Actions (“FSCAs”) must be reported to the relevant authorities of the EU member states. Manufacturers are required to take FSCAs defined as any corrective action for technical or medical reasons to prevent or reduce a risk of a serious incident associated with the use of a medical device that is made available on the market. An FSCA may include the recall, modification, exchange, destruction or retrofitting of the device.

The aforementioned EU rules are generally applicable in the EEA which consists of the 27 EU member states plus Norway, Liechtenstein, and Iceland.

Brexit and the UK Regulatory Framework

Since January 1, 2021, the Medicines and Healthcare Products Regulatory Agency (“MHRA”) has become the sovereign regulatory authority responsible for Great Britain (i.e. England, Wales and Scotland) medical device market according to the requirements provided in the Medical Devices Regulations 2002 (SI 2002 No 618, as amended)("UK Medical Devices Regulations") that sought to give effect to EU Medical Devices Directive and AIMDD whereas Northern Ireland broadly continues to be governed by EU rules according to the Northern Ireland Protocol. Following the end of the United Kingdom's ("UK" withdrawal from the EU ("Brexit") transitional period on January 1, 2021, all medical devices are required to be registered with the MHRA before being placed on the Great Britain market. The MHRA only registers devices where the manufacturer or their UK responsible person has a registered place of business in the UK. Since January 1, 2022, manufacturers based outside the UK need to appoint a UK responsible person that has a registered place of business in the UK to register devices with the MHRA.

On June 16, 2025, an amendment to the UK Medical Devices Regulations came into force intended to clarify and strengthen the post-market surveillance requirements for medical devices in Great Britain. This amendment aims to facilitate greater traceability of incidents and trends enabling the MHRA to act swiftly when needed to address safety issues and support the entire health system in better protecting patients. Under the UK Medical Devices Regulations, in order to be lawfully placed on the Great Britain market, class I (non-sterile, non-measuring or non-re-useable) medical devices need to be “UKCA” self-certified, and other medical devices need to be “UKCA”

certified by a UK approved body. However, certain medical devices in compliance with: (1) the EU Medical Devices Directive can continue to be placed on the Great Britain market until the sooner of certificate expiration or June 30, 2028; or (2) the EU Medical Devices Regulation can continue to be placed on the Great Britain market until June 30, 2030. The MHRA has confirmed that it intends to launch a consultation regarding the indefinite recognition of such medical devices in Great Britain which is expected this year.

In addition, the trade deal between the UK and the EU generally provides for cooperation and exchange of information between the parties in the areas of product safety and compliance, including market surveillance, enforcement activities and measures, standardization-related activities, exchanges of officials, and coordinated product recalls. As such, processes for compliance and reporting should reflect requirements from regulatory authorities.

Under the terms of the Northern Ireland Protocol, Northern Ireland follows EU rules on medical devices and devices marketed in Northern Ireland require assessment according to the EU regulatory regime. Such assessment may be conducted by an EU notified body, in which case a CE mark is required before placing the device on the market in the EU or Northern Ireland. Alternatively, if a UK notified body conducts such assessment, a “UKNI” mark and a CE mark are applied, and the device may only be placed on the market in Northern Ireland and not the EU.

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:

•design, development, manufacturing, and testing;

•product standards;

•product safety;

•product safety reporting;

•marketing, sales, and distribution;

•packaging and storage requirements;

•labeling requirements;

•content and language of instructions for use;

•clinical studies;

•record keeping procedures;

•advertising and promotion;

•recalls and field corrective actions;

•post-market surveillance, including reporting of deaths or serious injuries and malfunctions that, if they were to recur, could lead to death or serious injury;

•import and export restrictions;

•tariff regulations, duties, and tax requirements;

•registration for reimbursement; and

•necessity of testing performed in country by distributors for licensees.

The time required to obtain clearance or certification 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 Laws

In addition to FDA restrictions on marketing and promotion of drugs and devices, other federal, state, and foreign 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. 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 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.

More generally, expansion in the government’s role in the U.S. healthcare industry has led to (and may in the future lead to) additional regulation and oversight that impacts us. A recent example is the Wasteful and Inappropriate Service Reduction Model (“WISeR”) by CMS which tests the use of enhanced technology such as AI and machine learning to assess coverage determinations for a select set of items and services, including implantation of electric nerve stimulators, that CMS has determined (1) may pose concerns related to patient safety if delivered inappropriately, (2) have existing publicly available coverage criteria, or (3) may involve prior reports of fraud, waste, and abuse. WISeR will run for six performance years from January 1, 2026 to December 31, 2031 in six states: New Jersey, Ohio, Oklahoma, Texas, Arizona and Washington. So far, the impact on our overall sales volumes from WISeR cannot be quantified, but it has caused some confusion among customers in the six states that are part of the program.

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 medical devices are subject to some general principles set forth in EU legislation. According to the EU Medical Devices Regulation, only devices that are CE marked may be marketed and advertised in the EU in accordance with their intended purpose. Directive 2006/114/EC concerning misleading and comparative advertising and Directive 2005/29/EC on unfair commercial practices, while not specific to the advertising of medical devices, also apply to the advertising thereof and contain general rules, for example, requiring that advertisements are evidenced, balanced and not misleading. Specific requirements are defined at a national level. EU member states’ laws related to the advertising and promotion of medical devices, which vary between jurisdictions, may limit or restrict the advertising and promotion of products to the general public and may impose limitations on promotional activities with healthcare professionals. 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 EU 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.

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. In the U.S., 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 non-physician practitioners such as physician assistants and nurse practitioners, and teaching hospitals, as well as ownership and investment interests held by physicians and their immediate family members. 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. In the EU, there has also been a recent trend of increased regulation of payments and transfers of value provided to healthcare professionals or entities and many EU member states have adopted national "Sunshine Acts" which impose reporting and transparency requirements (often on an annual basis), similar to the requirements in the United States, on 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. In addition, responding to investigations of alleged violations of healthcare laws can be time-and resource-consuming and can divert management’s attention from the business. Any such investigation or settlement could increase our costs or otherwise have an adverse effect on our business. Even an unsuccessful challenge or investigation into our practices could cause adverse publicity and be costly to respond to.

Data Privacy and Security Laws

Numerous state, federal and foreign laws, regulations, and standards govern the collection, use, access to, confidentiality and security of health-related and other personal information, and could apply now or in the future to our operations or the operations of our partners. In the United States, numerous federal and state laws and regulations, including data breach notification laws, health information privacy and security laws, including HIPAA, and consumer protection laws and regulations govern the collection, use, disclosure, and protection of health-related and other personal information. In addition, certain foreign laws govern the privacy and security of personal data, including health-related data. For example, the General Data Protection Regulation imposes strict requirements for processing the personal data of individuals within the EEA. Privacy and security laws, regulations, and other obligations are constantly evolving, may conflict with each other to complicate compliance efforts, and can result in investigations, proceedings, or actions that lead to significant civil and/or criminal penalties and restrictions on data processing.

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, we have experienced seasonality in our first and fourth fiscal quarters, and we expect this trend to continue. In the U.S., we have experienced, and may in the future experience, higher sales in the fourth quarter as a result of patients having paid their annual insurance deductibles in full, thereby reducing their out-of-pocket costs. Conversely, in the first quarter, many U.S. patients' insurance deductibles reset, requiring more out-of-pocket costs, which negatively impacts our sales during this period. We have also begun to experience some seasonality during summer months in the U.S. and Europe, which we believe is attributable to the postponement of elective surgeries due to summer vacation plans of physicians and patients.

Human Capital

We take pride in our innovative and collaborative work environment, which we believe has been key to our success. We strive to maintain this environment by fostering an inclusive workforce, offering competitive compensation and benefits, promoting open communication, prioritizing employee health, wellbeing and engagement, and providing robust training and development programs.

Employees

As of December 31, 2025, we had 1,333 employees, of which 1,243 are in the U.S., 83 are in Europe and 7 are in Japan. We increased the number of employees by 7% during 2025 to support the growth of our business. As of

29

Table of Contents

December 31, 2025, 52% of our U.S. workforce identified as female, and 15% identified as a member of minority racial group.

None of our employees are currently subject to a collective bargaining agreement or represented by a trade or labor union. We consider our relationship with our employees to be good.

Code of Business Conduct and Ethics

Inspire is committed to conducting business in accordance with high ethical standards and applicable laws. We maintain, and all of our employees are expected to adhere to, our Code of Business Conduct and Ethics (the “Code of Conduct”), which serves as the foundation of our company’s culture. All employees and individual contractors are expected to certify annually that they understand and will comply with the expectations contained in the Code of Conduct. We maintain an anonymous hotline for employees to report concerns regarding violations of the Code of Conduct and a whistleblower policy addressing our policies and processes to protect the confidential anonymous reporting of concerns regarding accounting or auditing matters.

Compensation and Benefits

We strive to pay competitive salaries and maintain a comprehensive benefits package that helps our employees and their families maintain health and well-being—both physically and financially. Our human capital strategies, initiatives, and outcomes are reviewed on a regular basis with our Board’s Organization and Compensation Committee to ensure alignment with the company’s overall business strategies. The Committee engages an independent consulting firm to assess the market competitiveness of our compensation programs and offerings.

Inspire most recently completed a pay equity analysis in 2025. We expect to continue to review pay equity on a regular basis.

We believe strongly in providing employees with the opportunity to participate as owners of the company. Many of our full-time employees are eligible to receive stock awards, which may include stock options, restricted stock units, or performance stock units. All U.S. employees are also eligible to elect to participate in our employee stock purchase program.

Our standard employee benefits package is available to all full-time employees (except for variations required by state or country-specific laws). Standard U.S. employee benefits available to all full-time employees include medical, dental, and vision insurance, identity protection, disability insurance, life and AD&D insurance, 401(k) employer match, and paid holidays. Additionally, we recognize that Inspire employees have diverse needs for time off from work and maintain a flexible time off (“FTO”) policy, which provides all full-time employees the opportunity to take time off as needed without the need to accrue a specific amount of paid time off each year. Our FTO policy allows employees to take time off for any reason, including vacation, personal time, volunteering, school commitments, and religious holidays not observed by our paid holiday calendar.

Talent Acquisition

To facilitate our continued evolution and growth, it is imperative that we hire exceptional talent and invest in the growth and development of our existing employees. We develop and set an annual hiring plan to understand and plan for the organization’s talent recruitment and pipeline needs.

Inspire’s growth has required several strategies to attract talent and meet our growth plans, including a strong internal referral network. In addition to sourcing candidates, we also work with search partners as needed. We encourage internal job movement opportunities for employees to support development.

We follow a defined and consistent interview process for open positions, whether internal or external. In order to support our talent attraction efforts, we partner externally with organizations, universities, and colleges to assist with identifying talented pipelines. Internally we continue to build and train hiring managers on a structured interview process to assess talent.

Talent Management

We seek to foster a culture where learning is continuous and curiosity and innovation are encouraged. We believe in our people and their ability to accept new responsibilities and challenges, and to grow with us to contribute to our success. Growth is fostered through professional development and learning programs, as well as practical experience leading projects or teams.

New employees joining Inspire are provided with a comprehensive learning path consisting of two key components. First, they gain an understanding of our organization, including our products, the customers and patients we serve, and the regulatory requirements to which we are accountable. Next, training is conducted at the department level to build job role proficiency, and peer mentors may be assigned to help with acceleration of learning and onboarding.

On an ongoing basis, employees have the opportunity to engage in professional development to enhance their Inspire-specific knowledge and skills and their business acumen. These opportunities are available as scheduled in-person events or as just-in-time learning through unlimited access to LinkedIn Learning. Additionally, Inspire offers reimbursement (up to $10,000 per calendar year) for tuition and related expenses.

Developing our leaders is crucial for engagement and business success and we encourage employees to evolve in their roles. An established leadership development pathway supports the growth of our high performers from emerging leaders to effective managers, and further to strengthen coaching and performance management capabilities. Additionally, one-on-one coaching is available for our leaders through external partners.

On an annual basis, our leadership team participates in a talent review and succession planning exercise to identify organizational needs, individual development opportunities, and potential future leaders. This enables us to identify the resources and skill sets needed to meet our growth objectives while encouraging meaningful career and development conversations between leaders and direct reports. We also review pay twice per year for all employees and address any identified gaps.

Inclusion and Belonging

We strive to create a culture in which all employees feel heard, respected, and valued. All new employees participate in training focused on appropriate, respectful, and inclusive workplace behavior. The goals of the training are to encourage broad and diverse viewpoints to achieve the best outcomes for our patients, customers, and employees, and to build awareness of how our own behaviors impact our colleagues.

Charitable Giving

As a medical technology company, we are committed to enhancing the lives of patients through innovation. In 2023, we launched InspireGives, Inspire’s community outreach program aimed at serving the communities in which we live and operate through financial donations and volunteerism. Our contributions seek to provide crucial assistance to charitable organizations striving to treat critical illnesses, combat poverty and homelessness, ease hardship for people affected by disasters, eliminate barriers to equal opportunity, promote healthy sleep, and support underserved communities to address inequities in health outcomes.

Our employees are passionate about improving the lives of others, so we provide channels for our team members to identify opportunities to engage with charitable organizations and events in our communities. In 2025, we contributed nearly $175,000 to local and national charitable organizations including health care charities and charitable organizations addressing other related causes.

Sustainability

As our business continues to grow and develop, we recognize the importance of making responsible business decisions for the benefit of our stakeholders, including our stockholders, customers, employees, partners, the communities in which we work and live, as well as the planet. To that end, we have implemented a corporate sustainability program and set sustainability objectives. We published our fourth Sustainability Report in 2025,
