Authentidate Receives Nasdaq Deficiency Notice
Related to Minimum Bid Price
BERKELEY HEIGHTS, N.J.— December 20, 2007—Authentidate Holding Corp. (Nasdaq: ADAT), a worldwide provider of software and web-based services that enable enterprises and individuals to exchange information securely and conduct trusted business transactions, today announced that it has received a non-compliance notification from Nasdaq dated December 18, 2007 stating that for the last 30 consecutive business days, the closing bid price per share of the Company’s common stock has been below the $1.00 minimum per share requirement for continued listing as set forth in Nasdaq Marketplace Rule 4450(a)(5). The letter has no effect on the listing of the Company’s common stock at this time.
Pursuant to Nasdaq Marketplace Rule 4450(e)(2), the Company has been provided an initial period of 180 calendar days, or until June 16, 2008, to regain compliance. The letter states the Nasdaq staff will provide written notification that the Company has achieved compliance with Rule 4450(a)(5) if at any time before June 16, 2008, the bid price of the Company’s common stock closes at $1.00 per share or more for a minimum of 10 consecutive business days.
In the event that we were to receive notice that our common stock will be delisted, Nasdaq rules permit us to appeal any delisting determination by the Nasdaq staff to a Nasdaq Listings Qualifications Panel. In addition, in the event that a delisting determination was based solely on the Company’s non-compliance with the minimum bid price rule, we may be permitted to transfer the listing of our common stock to the Nasdaq Capital Market if the Company meets all of the other initial inclusion requirements for such market. In the event such a transfer is approved, we would receive an additional 180 calendar days to comply with the minimum bid price rule while on the Nasdaq Capital Market.
