FOR IMMEDIATE RELEASE

CardioNet, Inc. to Modify Business Structure

in Support of Growth Strategy

Company to Change Name to BioTelemetry, Inc.

Conshohocken, PA — (BUSINESS WIRE) — April 22, 2013 — CardioNet, Inc. (“CardioNet” or the “Company”) (NASDAQ:BEAT), the leading wireless medical technology company focused on diagnosing and monitoring cardiac arrhythmias, announced today that its Board of Directors has approved a plan to adopt a holding company structure to more effectively facilitate its ongoing growth plan.  Reflecting the change in structure, the Company will change its name to BioTelemetry, Inc. (“BioTelemetry”).

Joseph Capper, CEO and President for CardioNet commented, “Our strategy is to achieve sustained long-term growth by solidifying our leadership position in remote cardiac monitoring; building a leading research services business; and identifying markets that would benefit from the application of our wireless platform and proprietary technology.  As a result, we recently launched a more comprehensive sales approach in our patient services business and acquired Cardiocore in order to expand our research services capabilities.  Simultaneously, we have built an operational infrastructure capable of sustained growth in several areas of the developing mobile health services market.  Consequently, we expect to derive economic and functional benefits through the alignment of our adjacent businesses, each with distinct brand equity, under this holding company structure.

“We have chosen the name BioTelemetry for our holding company, as it best represents our clinical and technological focus moving forward.  CardioNet, Cardiocore and Braemar will become operating subsidiaries of BioTelemetry.  This creates a more flexible corporate structure in which to add new lines of business, as we seek to further leverage our core competencies.  We believe that BioTelemetry is extremely well positioned for success in today’s expanding mobile health services market, making this an opportune time for the Company.”

Pursuant to the plan, CardioNet, a Delaware corporation, will become a wholly owned subsidiary of BioTelemetry, a Delaware corporation, and the current stockholders of CardioNet will become stockholders of BioTelemetry with the same number and percentage of shares of BioTelemetry as they held of CardioNet prior to the creation of the holding company structure.  The common stock of BioTelemetry is expected to continue to trade on NASDAQ under the symbol “BEAT.”  CardioNet expects that the exchange of CardioNet shares of common stock for shares of BioTelemetry common stock will be treated as a tax free transaction.

The creation of the holding company structure requires the approval of CardioNet’s stockholders.  CardioNet has scheduled its annual meeting of stockholders for July 25, 2013, at which the approval of the holding company structure will be submitted for stockholder approval.  Once approved, the new name will take effect.

A registration statement relating to the issuance of BioTelemetry common stock in connection with the creation of the holding company structure has been filed with the SEC but has not yet become effective.  BioTelemetry may not issue shares of its common stock prior to the time the registration statement becomes effective.

This press release shall not constitute an offer to sell or a solicitation of an offer to buy, nor shall there be any sale of, these securities in any state of jurisdiction in which such an offer, solicitation or sale would be unlawful prior to registration or qualification under the securities laws of any such state or jurisdiction.
