Synthesis Energy Systems Announces Third Quarter 2010 Financial Results

Conference call scheduled for 8:00 a.m. Eastern Today

HOUSTON, May 6, 2010 /PRNewswire via COMTEX/ --Synthesis Energy Systems, Inc. (the "Company") (Nasdaq: SYMX), a global energy and gasification technology company, today announced results for the quarter ended March 31, 2010.

"We are encouraged by the steady progress we are making in all areas of our business as we continue to meet milestones and execute on our strategy," said Robert Rigdon, President and CEO of the Company.

"Since we launched our licensing business late last year, we have seen significant interest in our capability to efficiently and cost effectively gasify low rank coals as well as biomass, for conversion into fuels, chemicals and power," Rigdon added.

Third Quarter Financial Results (Unaudited)

For the quarter ended March 31, 2010, the Company reported total revenue of $2.6 million. These results included revenue for product sales at the Hai Hua joint venture plant of $2.3 million, which is a decrease of $0.1 million from the prior quarter. Additionally, the Company reported other revenues of $0.3 million which was generated from feasibility studies and other technical services provided in association with technology licensing.

Cost of sales and plant operating expenses were $2.7 million for the quarter ended March 31, 2010, a slight increase of $0.1 million from the prior quarter. The increase was due to costs incurred in providing services associated with technology licensing.

General and administrative expenses were $3.4 million during the quarter ended March 31, 2010, an increase of $0.5 million from the prior quarter. The increase is a result of consulting and royalty costs related to the development of the Company's global licensing business, as well as employee severance costs.

Project and technical development expenses were $0.3 million for the quarter ended March 31, 2010 and included advanced analytical flow modeling and other technical support for U-GAS® technology development.

The Company's operating loss for the quarter, which included $1.4 million of non-cash expenses, comprised of stock-based compensation expense and depreciation and amortization, was $5.2 million. This compares to an operating loss of $11.1 million for the quarter ended December 31, 2009 which included $7.7 million of non-cash expenses comprised of a $6.6 million impairment loss and other non-cash expenses.

At March 31, 2010, the Company had cash and cash equivalents of $45.8 million and working capital of $40.2 million.

About Synthesis Energy Systems, Inc.

The Company is an energy and technology company that builds, owns and operates coal gasification plants in China that utilize its proprietary U-GAS® fluidized bed gasification technology to convert low rank coal and coal wastes into higher value energy products, such as transportation fuel and ammonia. The Company also licenses its U-GAS® technology for biomass and coal applications worldwide and provides related services and equipment. The U-GAS® technology, which SES licenses from the Gas Technology Institute, gasifies coal 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 our ability 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) our ability to operate efficiently on a smaller scale, which enables us to construct plants more quickly, at a lower capital cost, and, in many cases, in closer proximity to coal sources. The Company currently has offices in Houston, Texas and Shanghai, China. For more information on SES, visit www.synthesisenergy.com or call (713) 579-0600
