INFORMATION CONTAINED IN THIS FORM 6-K REPORT

On June 20, 2016, Aegean Marine Petroleum Network Inc. (the " Company ") appointed PricewaterhouseCoopers S.A. (" PwC ") as the Company's independent auditor for the fiscal year ending December 31, 2016, and dismissed Deloitte Hadjipavlou Sofianos & Cambanis S.A. (" Deloitte ") as the Company's independent auditor. The Company's appointment of PwC and dismissal of Deloitte was approved by the audit committee of the board of directors of the Company (the " Audit Committee ").

The reports of Deloitte on the consolidated financial statements of the Company for the years ended December 31, 2015 and 2014 did not contain an adverse opinion or disclaimer of opinion and were not qualified or modified as to uncertainty, audit scope, or accounting principles.

During the years ended December 31, 2015 and 2014, and through June 20, 2016, there were no disagreements with Deloitte on any matter of accounting principles or practices, financial statement disclosures, or auditing scope or procedure, which such disagreements, if not resolved to the satisfaction of Deloitte, would have caused Deloitte to make reference thereto in its reports on the financial statements of the Company for such years.

For the preceding two years and through June 20, 2016, there was one "reportable event" as that term is described in Item 16F(a)(1)(v)(A) of Form 20-F. During the year ended December 31, 2014, management identified two material weaknesses in the Company's internal control over financial reporting, which were disclosed in the Company's annual report on Form 20-F for the year ended December 31, 2014, which was filed with the U.S. Securities and Exchange Commission (the " SEC ") on May 15, 2015. The first material weakness was that our controls over the preparation and review of bank reconciliations did not operate effectively.  The second material weakness was that there was an absence of an effectively-designed control to identify and disclose transactions with new related parties. Due to these material weaknesses, Deloitte concluded in its report on internal control over financial reporting, dated May 15, 2015, that "the Company has not maintained effective internal control over financial reporting as of December 31, 2014, based on the criteria established in  Internal Control — Integrated Framework (2013)  issued by the Committee of Sponsoring Organizations of the Treadway Commission." The Audit Committee discussed these material weaknesses with the Company's management and Deloitte. The Company did not have any disagreements with Deloitte on any matter of accounting principles or practices, financial statement disclosure, or auditing scope or procedure. The Company has since remediated these material weaknesses in its internal control over financial reporting, and with respect to the following year, Deloitte concluded in its report on internal control over financial reporting, dated April 28, 2016, that "the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2015." The Company has authorized Deloitte to respond fully to inquiries from PwC concerning the subject matter of the "reportable event" described above. During the years ended December 31, 2015 and 2014, and through June 20, 2016, there were no other "reportable events" as that term is described in paragraphs (A) through (D) of Item 16F(a)(1)(v) of Form 20-F.

The Company provided Deloitte with a copy of the disclosure it is making in this Report of Foreign Private Issuer on Form 6-K (this " Report "), and requested that Deloitte furnish the Company with a letter addressed to the SEC, pursuant to Item 16F(a)(3) of Form 20-F, stating whether Deloitte agrees with the statements made by the Company in this Report, and if not, the respects in which Deloitte does not agree. A copy of Deloitte's letter to the SEC dated June 24, 2016 is attached as Exhibit 1 to this Report.
