iRhythm Holdings, Inc.

Company Background iRhythm is a leading digital healthcare company that creates trusted solutions that detect, predict, and prevent disease. Our principal business is the design, development, and commercialization of device-based technology to provide ambulatory cardiac monitoring services that we believe allow clinicians to diagnose certain arrhythmias quicker and with greater efficiency than other services that rely on traditional technology. Each iRhythm product offering combines a wire-free, patch-based, 14-day wearable biosensor (United States Food and Drug Administration ( FDA )-cleared, Conformit Europ enne ( CE )-marked and Japan Pharmaceuticals and Medical Devices Agency ("PMDA")-approved, as applicable) that continuously records electrocardiogram ("ECG") data with a proprietary cloud-based data analytic software (also FDA-cleared, CE-marked and Japan PMDA-approved, as applicable) (such biosensor and software together, an "iRhythm ACM System") to help physicians monitor patients and diagnose arrhythmias. Since first receiving clearance from FDA for our technology in 2009, we have supported physician and patient use of this technology and provided ambulatory cardiac monitoring ("ACM") services from our Medicare-enrolled independent diagnostic testing facilities ( IDTFs ) with our qualified technicians.
