Item 8.01    Other Events.

On April 17, 2015, the Board of Directors (the “Board”) of Synthesis Energy Systems, Inc. (the “Company”) approved June 30, 2015 as the date for the Company’s Annual Meeting of Stockholders for the year ended June 30, 2014 (the “Meeting”) to be held at the Company’s principal executive offices located at Three Riverway, Suite 300, Houston, Texas 77056. The Board also approved April 27, 2015 as the record date for the Meeting. Only stockholders of record at the close of business on that date may vote at the meeting or any adjournment thereof.

Because the Meeting will be held more than 30 days from the anniversary of the Company’s Annual Meeting of Stockholders for the year ended June 30, 2013 (the “Prior Meeting”), the Company has set a new deadline for the receipt of any stockholder proposals submitted pursuant to Rule 14a-8 under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), for inclusion in the Company’s proxy materials for the Meeting. Such proposals must be delivered to Roger Ondreko, the Company’s Chief Financial Officer, at Synthesis Energy Systems, Inc., Three Riverway, Suite 300, Houston, Texas 77056 no later than the close of business on April 27, 2015 to be considered timely, pursuant to the terms of the Company’s Amended and Restated Bylaws, before the Company begins to print and send proxy materials. The Company recommends that such proposals be sent by certified mail, return receipt requested. Such proposals must also comply with the rules of the Securities and Exchange Commission regarding the inclusion of stockholder proposals in proxy materials, and may be omitted by the Company if not in compliance with applicable requirements.

Because the Meeting will be held more than 30 days from the anniversary of the Prior Meeting, in accordance with the Company’s Amended and Restated Bylaws, proposals of stockholders made outside of Rule 14a-8 under the Exchange Act must be received not later than the close of business on April 27, 2015 in order to be considered at the 2014 Annual Meeting of Stockholders. Such proposals must be delivered to the Roger Ondreko, the Company’s Chief Financial Officer, at Synthesis Energy Systems, Inc., Three Riverway, Suite 300, Houston, Texas 77056 and must also comply with all other requirements set forth in the Company’s Amended and Restated Bylaws and other applicable laws.
