Our RNS System Our RNS System, which is a compilation of several of our products, is a paradigm-shifting approach to treating epilepsy that combines the power of continuous iEEG monitoring with responsive neuromodulation. With our RNS System, we offer a personalized treatment option that delivers a safe and effective therapy for focal onset seizures originating anywhere in the brain. We believe our RNS System is superior in tolerability and efficacy to other neuromodulation approaches and provides clinicians with actionable insights based on their patients’ brain activity, facilitating better treatment decisions and optimizing patient care. Overview Our RNS System includes our RNS neurostimulator, our cortical strip leads and depth leads, and our Patient Remote Monitor, as well as other implantable and non-implantable accessories.
The implantable components of our RNS System include a neurostimulator, which is placed within the patient’s skull, and our RNS System leads with both cortical strip electrodes (on the surface of the brain) and depth electrodes (within the brain) that can be positioned according to clinician preference, as well as implantable accessories such as our burr hole cover. The neurostimulator is flush with the patient’s skull, and under the scalp, so that it is not visible externally. Placing the neurostimulator in the skull minimizes external noise and movement artifact so that it is able to sense even the most subtle brain signals and eliminates the need for long tunneled connectors between the chest and head which reduces the risk for breakage, migration and discomfort that can be associated with some other neuromodulation devices.

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 and only 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 350 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.

Overview We are a medical device company focused on transforming the lives of people living with epilepsy by reducing or eliminating the occurrence of debilitating seizures. Our novel and differentiated RNS System is the first and only commercially available, brain-responsive neuromodulation system that delivers personalized, real-time treatment at the seizure source. By continuously monitoring and analyzing the brain’s electrical activity, recognizing patient-specific abnormal electrical patterns, and responding in real time with imperceptible electrical pulses to prevent seizures, our RNS System is programmed by clinicians to deliver the precise amount of therapy when and where it is needed and provides exceptional clinical outcomes with approximately three minutes of stimulation on average per day.
Our RNS System is also the only commercially available device that records continuous brain activity data and allows clinicians to monitor patients not only in person, but also remotely, providing them the data they need to make more informed treatment decisions, thus optimizing patient care. We believe the therapeutic advantages of our RNS System, combined with the insights obtained from our extensive brain data set, offer a significant leap forward in epilepsy treatment. As of December 31, 2024, over 6,000 patients have received our RNS System. We believe our compelling body of long-term clinical data, demonstrating continuous improvement in outcomes over time, will support the continued adoption of our RNS System among the approximately 575,000 adults in the United States with drug-resistant focal epilepsy.

Manufacturing and Supply We currently manufacture our RNS System at and distribute all of our products from our approximately 53,000 square foot facility in Mountain View, California. This facility provides approximately 20,000 square feet of space for our production and distribution operations, including manufacturing, quality control and storage. We believe our existing facility will be sufficient to meet our current and near-term manufacturing needs. Our manufacturing and distribution operations are subject to regulatory requirements of the FDA’s Quality System Regulation, or QSR, for medical devices sold in the United States. The FDA monitors compliance with the QSR through periodic inspections of our facilities and may include our suppliers’ facilities as well.
We typically maintain several months’ worth of inventory on critical components. From time to time, we have experienced issues with our suppliers. To date, these issues have not had a material impact on our operations. We estimate that qualifying a second source supplier would be a lengthy process. Our suppliers are evaluated, qualified and approved through our supplier management program, which includes various evaluations, assessments, qualifications, validations, testing and inspection to ensure the supplier can meet acceptable quality and regulatory requirements. Order quantities and lead times for materials, components, and sub-assemblies purchased from suppliers are based on our forecasts derived from historical demand and anticipated future demand. We perform assembly, testing, inspection and final release activities for our RNS System at our Mountain View, California facility.

Behind the comparison

Sources and methodology

Price return uses split-adjusted daily closes and excludes dividends. Both stocks start on the first shared trading day within the selected window. Unavailable metrics leave gaps.

Financials use SEC canonical statements available by the displayed cutoff, retaining each company's fiscal period end. Annual and quarterly amounts are shown separately. P/E is unavailable when earnings do not support a positive ratio.

Business overlap uses industry tags from annual filings released in 2025. Each core activity receives full weight; each material activity receives one quarter of that weight. Rarer industries carry more weight. We sum the smaller exposure for each shared activity and divide it by the sum of the larger exposure for every activity in either company. This measures business overlap, rather than price correlation or expected returns.

Search eligibility requires distinct issuers, a shared core category and at least 20% weighted overlap, supported by industry or sector evidence and specific business activities. Broad classifications require stronger overlap within the same sector. Comparisons also need at least 252 shared price observations within two years, recent trading and a common sourced revenue or net-income trend. Missing P/E or gross margin alone does not exclude a comparison. The eligibility snapshot refreshes daily. Related comparisons use a separate, stricter peer rule; their ten-peer discovery limit does not limit search eligibility. Other stock pairs remain available in the comparison tool.

Statements available through 2026-10-22. Industry snapshot: 2025-12-31 · 5,721 classified issuers.
