Arrhythmia Research Technology, Inc. Announces Delay in Finalizing Second Quarter Results

Fitchburg, Massachusetts
Arrhythmia Research Technology, Inc. (NYSE MKT:HRT) (the "Company") reported today that it was unable to file its quarterly report on Form 10-Q for the three months ended June 30, 2013 within the automatic extension of its due date to August 19, 2013 afforded by its filing of a Form 12b-25 Notification of Late Filing with the Securities and Exchange Commission.
The delay in filing is due to an ongoing internal review by the Audit Committee and the Company's independent auditor relating to the valuation of the deferred tax assets. As of today's date, the review is not complete. However, for the quarter ended June 30, 2013, the Company preliminarily expects to report the following:

Consequently, the Company is unable to determine with reasonable certainty at this time the significance of any such adjustments and their effect on the net loss, total assets and stockholders' equity. Management is working diligently with its Audit Committee and the Company's independent auditor to determine whether any potential adjustments are required and the extent thereof. The Company expects to finalize the 10-Q by September 16, 2013. However, until the review is complete and a final determination is made, the Company cannot provide further assurance regarding the results of operations for the affected periods or whether adjustments will be required.
Salvatore Emma, Jr., the Company's President and Chief Executive Officer, stated "Management and our auditors are doing everything possible to bring our internal review of the valuation of deferred tax assets to a timely completion."
