Synthesis Energy Systems, Inc. Reports Fiscal 2014 Financial Results and Provides Business Update

Company Reports $17.5 Million Revenue for the Year Versus $0.6 Million for the Prior Year

HOUSTON, September 10, 2014 -- Synthesis Energy Systems, Inc. (SES) (NASDAQ: SYMX) today reported financial and operating results for its fiscal 2014 year and fourth quarter, ended June 30, 2014.

“Our focus during this past fiscal year has been on delivering results from our joint venture operations in China and on laying a strong foundation for commercialization. Now, with our technology proven at our operating plants, the company is partnering with major global technology, manufacturing and operating companies to facilitate entry into the large global energy and chemicals markets where we believe our technology can deliver value and make a positive impact,” said Robert Rigdon, SES President and Chief Executive Officer. “Our technology’s success is gaining the attention of major companies around the world. Our core technology differentiation for cleanly and economically processing a wide range of solid-based energy feedstocks, which we believe is the future of gasification, is the key that has enabled our partnering success during our fiscal 2014.”

“Our initial strategic partnerships are with GE Packaged Power, Midrex Technologies and Zhangjiagang Chemical Machinery (ZCM). Together with GE, we are targeting the global market for distributed power generation. We signed our first Letter of Intent in January 2014. Our business development effort, along with collaborators, IEG and Tuten, are progressing the development of a 160 MW power plant offering for K-Electric, using SES Gasification Technology and GE turbines,” said Rigdon. “Our ZCM China joint venture, Jiangsu Tianwo-SES Clean Energy Technologies (T-SEC), is an example of a regional partnership extending across multiple industrial sectors in China and select Asian markets. This partnership, which launched operations in April, is intended to open new channels to the market and strengthen our manufacturing and fulfillment capability. Most recently in late May, we entered into an exclusive agreement for the joint marketing of coal gasification-based Direct Reduced Iron (DRI) facilities with Midrex and, together, we have engaged T-SEC to assist us with our initial focus, which is on DRI in China. This collaboration is intended to provide an economical and clean technology product offering for the production of Direct Reduced Iron product for the steel industry from coal-based energy, versus natural gas.”

Rigdon added, “We believe the combined strengths of these partnerships and joint product offerings will lead to faster, multiple deployments of SES’s clean energy gasification systems to address the ever-increasing and varied needs of the global energy and chemicals landscape. We are hopeful that these initial partnerships will begin to contribute to our financial results during fiscal 2015 while we continue to push new initiatives forward, to expand our global footprint.”

“Also in fiscal 2014, we assumed operational control of Xuecheng Energy’s methanol operations adjacent to our Zao Zhuang (ZZ) JV plant and started producing and selling methanol during our second fiscal quarter. We have taken ZZ from zero revenue the previous two years to delivering $14.9 million this past fiscal 2014. This was accomplished in an exceptionally challenging methanol price environment during the last six months in China. Because of the additional coke oven gas feedstock that we expect to come on line soon, combined with other technical and commercial optimizations now underway, we expect continuing improvement in financial results from ZZ. To that end, we have placed more experienced and high level resources to strengthen and accelerate operational capabilities and improve the financial performance of all our global growth initiatives, including our core operating plants, China joint venture, DRI steel and distributed power,” concluded Rigdon.

Recent Corporate Highlights

Zao Zhuang Joint Venture Methanol Plant (ZZ) – Since taking control of Xuecheng Energy’s methanol operations adjacent to the plant on October 31, 2013, ZZ has successfully been producing methanol primarily from coke oven gas. This past quarter, the facility produced 13,628 tonnes of methanol while generating $4.4 million in revenues from the sale of 12,891 tonnes of methanol; $14.9 million in revenues were generated in fiscal 2014. SES is focused on reducing unit costs and forced outages, and has been able to generate revenues and operate in different modes based on market conditions. The operations team has managed ZZ under challenging methanol market conditions but has contractually secured new feedstock resources, including 30% to 40% additional COG feedstock from Shandong Shenghuo Xulong Coal Chemical Company (Red Leaf), to drive down unit production costs. SES owns 97.6% of the ZZ JV.

Yima Joint Venture Methanol Plant (Yima) – Yima, which had been placed in a second short-term outage in July by the JV to complete remaining “punch-list items,” has recently undergone a significant management restructuring with day-to-day plant management and operational control now under the operations of its parent company, Henan Coal and Chemical Industry Group. There are no asset ownership changes. The new operations management team is experienced at running and optimizing a methanol plant of Yima’s scale. This team is successfully operating two other large-scale methanol plants and the group General Manager is a respected leader who is known by SES’s China team. SES continues to own 25% of the Yima JV.

SES strengthened the company’s operational capabilities in August. Charles Costenbader was moved from CFO to Chief Operating Officer, and Roger L. Ondreko was moved from Chief Accounting Officer to Chief Financial Officer. Both Messrs. Costenbader and Ondreko report to Mr. Rigdon.

SES appointed Charles M. Brown to its Board of Directors in July, bringing the total number of board members to eight, seven of whom are independent. Mr. Brown has led 20 different operating businesses and more than two dozen factories around the world in a wide variety of industrial and consumer product categories. He most recently served as President, CEO and a board member of Flow International Corporation, from 2007 until its sale in 2014.

Fiscal Fourth Quarter 2014 Financial Results (Unaudited)

The Company reported $4.4 million of revenue for the three months ended June 30, 2014, versus $192,000 for the three months ended June 30, 2013. The increase in revenue was primarily due to ZZ JV methanol revenue.

The Company’s operating loss for the fourth quarter of fiscal 2014 was improved to $4.1 million versus an operating loss of $5.5 million for the fourth quarter of fiscal 2013. The decrease in operating loss was primarily due to 30% reduction in overall general and administrative expenses and reduction in non-cash stock-based compensation expenses.

The net loss attributable to stockholders for the fourth quarter of fiscal 2014 was $4.5 million, or $0.06 per share, versus a loss of $5.7 million, or $0.09 per share, for the prior year’s fourth quarter.

As of June 30, 2014, the Company had cash and cash equivalents of $19.4 million and working capital of $11.4 million.

Fiscal 2014 Financial Results (Unaudited)

For the fiscal year ended June 30, 2014, total revenues were $17.5 million versus $0.6 million for fiscal 2013.The increase in revenue was primarily due to $14.9 million increase in product sales for the ZZ Joint Venture and plant and equipment sale of $2.6 million to the Yima Joint Venture.

The operating loss for fiscal 2014 was $13.6 million compared to an operating loss of $18.4 million for fiscal 2013. The reduction was due to a restructuring of the Company’s China business, generating a significant general and administrative expense reduction of $3.64 million from the prior fiscal year.

The net loss attributable to stockholders for fiscal 2014 was $14.2 million or $(0.22) per share versus $19.9 million or $(0.33) per share for fiscal 2013.
