CardioNet Completes $110 Million in Private Financing

CardioNet’s Equity Bridge Financing is One of the Largest in the Medical Technology Sector Since January 2000

NEW ORLEANS--(BUSINESS WIRE)--San Diego-based CardioNet, Inc., the leading provider of wireless mobile cardiac outpatient monitoring solutions, announced today that it has closed on $110 million in private financing, making it one of the largest private placements of equity bridge financing in the medical technology sector since January 2000, according to James M. Sweeney, CardioNet’s Chairman and CEO. CitiGroup Global Markets, Inc. served as the lead placement agent for this financing. Sun Trust Robinson Humphrey served as co-placement agent.

CardioNet has raised close to $200 million in private debt and equity over the past seven years to develop its proprietary technology platform focused on wireless solutions to a broad array of health-related diseases.

Sweeney said, “This significant round of funding clearly demonstrates the strong market support that exists for the proprietary CardioNet technology, the highly competitive business model of the company and the future of wireless telemedicine. We expect to be able to leverage our solid financial position to further solidify our leading position in the provision of our services to physicians and their patients nationwide.”

This month, the respected Journal of Cardiovascular Electrophysiology¹ published a first-of-its-kind peer review study that found CardioNet’s Mobile Cardiac Outpatient Telemetry (MCOT) technology nearly three times more effective at detecting and diagnosing clinically significant arrhythmias compared to existing mobile cardiac monitoring devices typically prescribed by physicians. Cardiac arrhythmia is one of the most common, yet potentially dangerous, heart conditions affecting more than four million Americans, accounting for more than 780,000 hospitalizations and 500,000 deaths each year, according to the American Heart Association.
