SYNTHESIS ENERGY SYSTEMS, INC. ANNOUNCES FINANCIAL RESULTS FOR
THE SECOND QUARTER OF FISCAL 2011

— Reports Improved Operating Performance —

HOUSTON, February 8, 2011 — Synthesis Energy Systems, Inc. (Nasdaq: SYMX), a global energy and gasification technology company that provides products and solutions to the energy and chemicals industries, today announced financial results and improved operating performance for the second quarter of fiscal 2011 ended December 31, 2010.

“We continue to make progress in our operating performance and in our licensing business,” stated Robert Rigdon, President and CEO. “Our licensing business is being bolstered by technology advancements that we have demonstrated on a commercial scale at our Zaozhuang (ZZ) joint venture plant in China. Our partners, customers and licensees, as well as other groups we’re talking to in China and other emerging markets, are taking note of the significant competitive advantages of our technology, including reduced emissions and improved margins.”

Second Quarter 2011 Financial Results (Unaudited)

Total revenue increased $0.3 million for the three months ended December 31, 2010, to $2.9 million, versus $2.6 million for the three months ended December 31, 2009.

Product sales from the Company’s ZZ joint venture plant increased to $2.6 million for the three months ended December 31, 2010, compared to $2.5 million for the three months ended December 31, 2009. For the three month periods ended December 31, 2010 and 2009, the plant operated for 73% and 83% of the time, respectively. For both of the three month periods ended December 31, 2010 and 2009, the plant’s availability for production was 97%.

Technology licensing and related services revenues for the three months ended December 31, 2010 were $0.3 million, reflecting the value of the coal contributed by Ambre Energy in exchange for testing of the coal at the ZZ joint venture plant. There were no technology licensing and related services revenues for the three month ended December 31, 2009.

There were no other revenues for the three months ended December 31, 2010. There were $0.1 million of other revenues for the three months ended December 31, 2009, related to a sponsorship grant pertaining to lignite testing at the ZZ joint venture plant.

The Company reduced its operating loss for the second quarter of fiscal 2011 to $3.5 million, a decrease from the $11.1 million reported in the second quarter of fiscal 2010. The $7.6 million improvement was primarily due to a $6.6 million asset impairment loss recorded in the prior year second fiscal quarter related to our Golden Concord joint venture project, an improved operating margin at the ZZ joint venture plant, and lower project and technical development and stock-based compensation expenses. These items were partially offset by an increase in G&A expenses resulting from new business development activities.

The net loss attributable to stockholders for the second quarter of fiscal 2011 declined to $3.6 million, or $0.07 per share, versus a net loss of $8.2 million, or $0.17 per share, for the prior year’s second quarter.

At December 31, 2010, the Company had cash and cash equivalents of $34.2 million and working capital of $31.1 million.

About Synthesis Energy Systems, Inc.

SES provides technology, equipment and engineering services for the conversion of low rank, low cost coal and biomass feedstocks into energy and chemical products. Its strategy is to create value through providing technology and equipment in regions where low rank coals and biomass feedstocks can be profitably converted into high value products through its proprietary U-GAS^® fluidized bed gasification technology, which SES licenses from the Gas Technology Institute. U-GAS^® gasifies coal cost effectively, without many of the harmful emissions normally associated with coal combustion plants. The primary advantages of U-GAS^® relative to other gasification technologies are (a) greater fuel flexibility provided by the ability of SES to use all ranks of coal (including low rank, high ash and high moisture coals, which are significantly cheaper than higher grade coals), many coal waste products and biomass feed stocks; and (b) the ability of SES to operate efficiently on a smaller scale, which enables the construction of plants more quickly, at a lower capital cost, and, in many cases, in closer proximity to coal sources. SES currently has offices in Houston, Texas, and Shanghai, China. For more information on SES, visit www.synthesisenergy.com or call (713) 579-0600.
