EXPLANATORY NOTE



Delta Technology Holdings Limited (the “Company”)
is filing this Amendment No. 1 on Form 20-F/A (the “Form 20-F/A”) to amend its annual report on Form 20-F for the fiscal
year ended June 30, 2016 (the “2016 Form 20-F”) as originally filed with the Securities and Exchange Commission (the
“SEC”) on November 15, 2016 in response to the SEC’s letter to the Company of March 14, 2017 instructing the
Company to provide all the information required by Item 16F of Form 20-F. Accordingly, Item 16F of the 2016 Form 20-F is deleted
in its entirety and replaced with the following new Item 16F. In addition, the Company is filing as an exhibit a letter from its
former auditor as required to Item 16F(a)(3) of the Form 20-F.



Other than as expressly set forth above,
this Form 20-F/A does not, and does not purport to, revise, update, amend or restate the information presented in any Item of the
2016 Form 20-F or reflect any events that have occurred after the filing of the 2016 Form 20-F.



Item
16F.      Change in Registrant's Certifying Accountant.



(a)        Former Independent
Registered Public Accounting Firm



On April 30, 2016, our former independent
registered public accounting firm, Dominic K.F. Chan & Co. changed its name to DCAW (CPA) Limited (“DCAW”). On
November 14, 2016, DCAW merged with Centurion ZD CPA Limited (“Centurion”). Consequently, on November 14, 2016, DCAW
resigned as our independent registered public accounting firm and on the same day, our board of directors approved the resignation
of DCAW and Centurion assuming the role of the Company’s independent public accounting firm, effective immediately.



The reports of DCAW on our financial statements
for the fiscal years ended June 30, 2014 and 2015 did not contain an adverse opinion or a disclaimer of opinion and were not qualified
or modified as to uncertainty, audit scope or accounting principles. During the fiscal years ended  June 30, 2014 and 2015,
and in the subsequent interim periods through November 14, 2016, there were no disagreements with DCAW on any matter of accounting
principles or practices, financial statement disclosure or auditing scope and procedure which, if not resolved to the satisfaction
of DCAW, would have caused DCAW to make reference to the matter in its report.



During the fiscal years ended June 30, 2014
and 2015, and in the subsequent interim periods through November 14, 2016, there were no disagreements with DCAW on any matter
of accounting principles or practices, financial statement disclosure, or auditing scope or procedure, which disagreement(s), if
not resolved to the satisfaction of DCAW, would have caused it to make reference to the subject matter of the disagreement(s) in
connection with its reports.



We provided DCAW with a copy of the foregoing
disclosures and requested DCAW to furnish us with a letter addressed to the Securities and Exchange Commission stating whether
or not it agrees with the above disclosures. A copy of the letter furnished pursuant to that request is filed as Exhibit 16.1 to
this Amendment No. 1 to the Annual Report on Form 20-F.



(b)        New Independent
Registered Public Accounting Firm



On November 14, 2016, we appointed Centurion
ZD CPA Limited (“Centurion”) as our new independent registered public accounting firm, effective immediately. During
the fiscal years ended June 30, 2014 and 2015, and during all subsequent interim periods through November 14, 2016, we did not
consult Centurion regarding the application of accounting principles to a specified transaction, either completed or proposed,
or the type of audit opinion that might be rendered on our financial statements, and neither a written report was provided to us
nor oral advice was provided that Centurion concluded was an important factor considered by us in reaching a decision as to the
accounting, auditing or financial reporting issue; or any matter that was either the subject of a disagreement (as defined in Item
16F(a)(1)(iv) of Form 20-F and the related instructions to this Item) or a reportable event (as described in Item 16F(a)(1)(v)
of Form 20-F.
