Authentidate Holding Corp. Reports Fiscal 2012 First Quarter Financial Results

- Company to Host Investor Conference Call Tuesday, November 15^th at 4:30 pm ET -

BERKELEY HEIGHTS, NJ – November 10, 2011 — 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 2012 first quarter ended September 30, 2011.

Selected highlights for the quarter include:

After the end of the quarter we received our security clearance for the VA project and strengthened our balance sheet with net proceeds of approximately $3.64 million from a registered direct offering of our common stock and warrants completed in October 2011.

Ben Benjamin, Chief Executive Officer of Authentidate, stated, “During fiscal 2012 we have continued to make solid progress with each of our core service offerings and have added some additional sales and support staff, as evidenced by the increase in our expenses for the period, to better position the company to take advantage of our near term opportunities. With respect to our VA telehealth project, we have deployed our infrastructure at the primary project site in Austin TX and have received our security clearance to operate. While this process has taken longer than we expected and delayed our ability to generate revenues, we have made significant progress and believe we are close to moving to the next phase of our project. We continue to work with project directors at the VA to implement our solutions as quickly as possible and we have been meeting with regional purchasing coordinators to demonstrate our telehealth products and services. As the VA enters into its new budget cycle for fiscal 2012 that started in October, we believe we are well positioned for significant growth as we start taking orders for this project and we are gearing up to manufacture additional product to support the VA as well as other growth in this market. Regarding our other solutions, we have begun to work with some new customers for our hospital discharge solution which we believe will give us additional momentum in this market and we are continuing to experience increased customer interest in this solution as well as our referral and order management solution as hospitals and other healthcare providers look for ways to manage costs, comply with new rules and regulations and coordinate care for their patients. As always, we will update our shareholders as opportunities in our marketplace develop.”

Mr. Benjamin concluded, “Although revenues increased for the quarter compared to the prior year period, we are not satisfied with the pace of our revenue growth. Based on customer interest, we believe market awareness of our solutions is increasing and that we are well positioned for increased revenue growth from each of our product and service offerings as we move through fiscal 2012 and beyond. We strengthened our balance sheet with the net proceeds from our registered direct offering in October which will help to support our growth initiatives as our markets develop. While economic conditions remain very challenging, we believe we will benefit from government healthcare reforms that begin to take effect in January 2012 as well as industry trends that are all geared towards significantly reducing costs, shortening the length of hospital stays, reducing hospital readmissions, shifting patient care towards wellness and preventative care programs and automating healthcare records and processes. We believe the fundamental value proposition of healthcare information technology remains strong and that our products and services will help contribute to a more efficient healthcare system.”

Total revenues for the three months ended September 30, 2011 were approximately $751,000 compared to $705,000 for the same period last year. These results reflect an increase in revenues from our telehealth products and services partly offset by lower revenues from our hosted software services due primarily to the acquisition of one of our customers and the related contract expiration. Total revenues for the first quarter of fiscal 2012 decreased approximately 3.6% compared to the fourth quarter of fiscal 2011 due primarily to lower hosted services revenues for the current period which were offset in part by higher telehealth revenues.

Net loss from continuing and discontinued operations for the quarter ended September 30, 2011 was $1,915,000, or $0.04 per share, compared to $1,597,000, or $0.04 per share, for the prior year period. The net loss for the quarter reflects higher selling expenses, special shareholder meeting costs and stock compensation expenses which offset higher revenues for the period. The net loss for the prior year period also reflects a gain on the sale of certain non-core assets of approximately $351,000 offset in part by a loss from discontinued operations of approximately $186,000.

At September 30, 2011, cash, cash equivalents and marketable securities amounted to approximately $938,000 and working capital for continuing operations was approximately $3,155,000. In October 2011, the company received net proceeds of approximately $3,638,000 from a registered direct offering of its common stock and warrants which will be used for working capital and general corporate purposes, including to support opportunities for future growth.
