EXPLANATORY NOTE



Delta Technology Holdings Limited is filing
this Amendment No. 1 (the “Amendment No.1”) to the Annual Report on Form 20-F for the fiscal year ended June 30, 2015
originally filed with the Securities and Exchange Commission (the “Commission”) on November 17, 2015 (the “Original
Report”) solely for the purpose of amending certain disclosure under Item 16F Change In Registrant’s Certifying Accountants
and filing the letter from Marcum LLP addressed to the Commission regarding disclosure provided in Item 16F as Exhibit 99.1.



Other than as expressly set forth above,
this Amendment No. 1 does not, and does not purport to, amend, update or restate the information in any other items of the Original
Report, or reflect events that have occurred after the Original Report was filed.



|ITEM 16F. | CHANGE IN REGISTRANT’S CERTIFYING ACCOUNTANTS
|--------- | ---------------------------------------------



On February 25,
2012, Marcum LLP (“Marcum”) was engaged to act as the Company’s independent registered public accounting firm.
Upon consummation of the Acquisition, Delta’s accounting firm, Dominic K.F. Chan & Co (“Dominic Chan”), became
the Company’s principal independent registered public accounting firm and Marcum’s engagement as the Company’s
principal independent register public accounting firm therefore ended.  Marcum was notified of their termination on November
16, 2015.



The reports of Marcum
on the Company’s financial statements as of and for the years ended October 31, 2013 and 2012 contained no adverse opinion
or a disclaimer of opinion and were not qualified or modified as to uncertainty, audit scope or accounting principles except that
such report on the Company’s financial statements contained an explanatory paragraph related to the Company’s ability
to continue as an going concern. As disclosed in Item 15 of the Company’s Annual Report on Form 20-F for the fiscal year
ended October 31, 2013, the Company’s management and Board of Directors identified certain matters that constituted material
weaknesses in the Company’s internal control over financial reporting. During the years ended October 31, 2013 and 2012,
and the subsequent interim period through the date of the termination of Marcum’s engagement (“Engagement Period”),
there were no “disagreements,” as that term is defined in Item 16F(a)(1)(iv) of Form 20-F and the related instructions
to Item 16F of Form 20-F, with Marcum on any matter of accounting principles or practices, financial statement disclosure or auditing
scope or procedure, which disagreements, if not resolved to the satisfaction of Marcum, would have caused it to make reference
to the subject matter of the disagreements in connection with its reports on the consolidated financial statements of the Company.
Furthermore, except for the material weaknesses in the Company’s internal control over financial reporting discussed above,
no “reportable events,” as that term is defined in Item 16F(a)(1)(v) of Form 20-F, occurred within the periods covered
by Marcum’s reports on the consolidated financial statements of the Company, or subsequently up to the date of the termination
of Marcum’s engagement.



The Company provided
Marcum with a copy of the foregoing disclosure and requested that Marcum furnish it with a letter addressed to the Securities and
Exchange Commission stating whether or not Marcum agrees with the statements made above, and if not, stating the respects in which
it does not agree. A copy of such letter, dated November 23, 2015, is filed as Exhibit 99.1 to this Amendment No. 1.



During the years
ended October 31, 2013 and 2012 and the subsequent interim period prior to Dominic Chan’s appointment, neither the Company
nor anyone on its behalf consulted Dominic Chan regarding either (i) the application of accounting principles to a specified transaction,
either completed or proposed; or the type of audit opinion that might be rendered on the Company’s consolidated financial
statements, and either a written report was provided to the Company or oral advice was provided that Dominic Chan concluded was
an important factor considered by the Company in reaching a decision as to the accounting, auditing or financial reporting issue;
or (ii) any matter that was either the subject of a “disagreement” or a “reportable event” as described
above.
