Authentidate Holding Corp. Reports Fiscal 2013 First Quarter Results

BERKELEY HEIGHTS, NJ - November 14, 2012 - Authentidate Holding Corp. (Nasdaq: ADAT), a provider of secure web-based software applications and telehealth products and services for healthcare organizations, today announced financial results for the fiscal 2013 first quarter ended September 30, 2012.

Selected highlights for the first quarter include:

Following the end of the first quarter, the company announced that the VA had completed the required test-in phase for our Interactive Voice Response (IVR) vital signs monitoring solution for use with the VA’s weight management protocol (TeleMOVE) and had given its approval for VA facilities throughout the country to order and use the IVR solution for TeleMOVE patients. VA facilities can use the IVR solution on a stand-alone basis or in combination with the EHC device to help monitor patients that require a flexible, mobile solution to manage their weight according to VA TeleMOVE care program guidelines. The IVR solution uses the same web service as the EHC solution and provides VA Clinicians with an additional way to remotely monitor their mobile patients and enhance patient care in their national Care Coordination Home Telehealth program. Other Disease Management Protocols for the IVR solution are currently being pilot tested and should be approved for national deployment in the near future.

Ben Benjamin, Chief Executive Officer of Authentidate, stated, “We are off to a good start in fiscal 2013 with all of our core products and services. Since the beginning of the fiscal year, the VA has granted approvals for national deployment for both our EHC and IVR telehealth solutions and we have made progress with new and existing customers for our hospital discharge and referral management solutions. During the quarter we also made several enhancements to our telehealth products and services to lower costs and better position the company for growth and profitability. As healthcare providers embrace information technology to control costs, coordinate patient care and comply with regulatory reforms, we are seeing an increasing interest in all of our products and services. Our ability to combine two or more of our solutions to meet customer needs to coordinate cost-effective post-acute care for patients differentiates our offerings and positions us well to help healthcare organizations meet emerging market needs. During fiscal 2013 we plan to focus primarily on ramping up the number of EHC and IVR products and services we provide to the VA, adding new customers and partner relationships for our hospital discharge solution and increasing the utilization of our referral management services by our

existing customers. We also plan to actively pursue opportunities to provide our telehealth solutions to our existing commercial customer base as well as other private sector telehealth opportunities as this market develops. We believe we have a significant opportunity to grow our revenues during fiscal 2013 and beyond as we move to the growth stage of our telehealth project with the VA and we pursue private sector opportunities for growth from our telehealth, hospital discharge and referral management products and services.”

Mr. Benjamin concluded, “Although economic conditions remain challenging, we believe we are very well positioned for growth and profitability as healthcare organizations look for ways to address market trends and regulatory reforms. Our revenues are moving in the right direction and we believe the pace of our revenue growth will improve significantly as we execute on our growth plans for our VA telehealth project and our other products and services. We appreciate the support of the investors in our recent secured loan transactions as the proceeds and the extension of the maturity date on our existing notes will help support our growth plans. We believe we have a significant opportunity ahead of us and we are excited about the future for our company. We will update our shareholders as opportunities in our market develop.”

Revenues for the quarter ended September 30, 2012 were approximately $921,000 compared to $751,000 for the prior year period. These results reflect an increase in revenues from both our telehealth products and services and our hosted software services. Revenues for the first quarter decreased slightly compared to the fourth quarter of fiscal 2012 due primarily to the timing of telehealth product shipments.

Net loss for the quarter ended September 30, 2012 was $2,515,000, or $0.11 per share, compared to $1,915,000, or $0.09 per share, for the prior year period. The increase in net loss for the quarter is due primarily to the non-cash amortization of the debt discount on the company’s senior secured notes payable and higher selling, support and stock compensation expenses.

At September 30, 2012, cash, cash equivalents and marketable securities amounted to approximately $3,652,000 and the company had working capital of approximately $6,347,000.
