PART III — NARRATIVE

State below in reasonable detail the reasons why Forms 10-K, 20-F, 11-K, 10-Q, N-SAR, or the transition report or portion thereof, could not be filed within the prescribed time period.

As previously reported, on January 27, 2016, Peachstate Health Management LLC, d/b/a AEON Clinical Laboratories (“AEON”) was merged into a newly formed acquisition subsidiary of Authentidate Holding Corp. (the “Company”) (the “AEON Acquisition”), pursuant to a definitive Agreement and Plan of Merger dated November 18, 2015, as Amended and Restated on January 26, 2016 (the “Merger Agreement”). Effective as of the closing of the AEON Acquisition, (i) Mr. Sonny Roshan, the current Chairman of AEON, was appointed the Chairman of the Company, which is an executive officer position at the Company, (ii) Mr. Richard Hersperger, the current Chief Executive Officer of AEON, assumed the role of Chief Executive Officer of the Company and (iii) the Company’s then Chief Executive Officer, Ian C. Bonnet, resigned. Additionally, pursuant to the terms of the Merger Agreement, effective with the closing of the AEON Acquisition, Mr. William A. Marshall agreed to tender his resignation as Chief Financial Officer, Treasurer and Principal Accounting Officer of the Company, to be effective no later than March 1, 2016. As the Company and Mr. Marshall did not further extend the term of his employment, Mr. Marshall’s resignation as the Chief Financial Officer, Treasurer and Principal Accounting Officer of the Company became effective on March 1, 2016. On March 3, 2016, the Company appointed Thomas P. Leahey its new interim Chief Financial Officer, effective immediately.

The principal reason for the delay in the filing of the Quarterly Report on Form 10-Q for the quarter ended March 31, 2016 was the AEON Acquisition, which, among other things, resulted in a complete change in the management of the Company. Additional time is needed for AEON and the Company to compile and complete all necessary financial information for the first combined period related to the its financial statements. As a result, the Company’s Quarterly Report on Form 10-Q for the quarter ended March 31, 2016 could not, without unreasonable effort and expense, have been filed before its May 16, 2016 due date.

PART IV — OTHER INFORMATION

(1)  Name and telephone number of person to contact in regard to this notification:

Richard Hersperger	678	276-8412
(Name)	(Area Code)	(Telephone Number)

(2)  Have all other periodic reports required under Section 13 or 15(d) of the Securities Exchange Act of 1934 or Section 30 of the Investment Company Act of 1940 during the preceding 12 months or for such shorter period that the registrant was required to file such report(s) been filed? If answer is no, identify report(s).    YES  x    No  ¨

(3)  Is it anticipated that any significant change in results of operations from the corresponding period for the last fiscal year will be reflected by the earnings statements to be included in the subject report or portion thereof?    YES  x    No  ¨

If so, attach an explanation of the anticipated change, both narratively and quantitatively, and, if appropriate, state the reasons why a reasonable estimate of results cannot be made.

Although the Company was the surviving legal entity in the AEON Acquisition, the transaction is accounted for as a reverse merger with AEON deemed as the accounting acquirer. Consequently, AEON’s historical results will be carried forward and AEON’s operations will be included in the financial statements commencing on the effective date of the AEON Acquisition. Accordingly, the Company expects that the amounts of revenue, assets, liabilities and shareholder’s equity for the quarter ended March 31, 2016 will differ significantly from the results of operations reported in its Quarterly Report on Form 10-Q for the quarter ended March 31, 2015. The Company is unable to provide an accurate quantitative estimate of the results for the quarters ended March 31, 2016 and 2015, as it has not yet completed the information necessary to provide such an estimate.
