SES Forward - looking Statements This presentation includes "forward - looking statements" within the meaning of Section 27 A of the Securities Act of 1933 , as amended, and Section 21 E of the Securities Exchange Act of 1934 , as amended . All statements other than statements of historical fact are forward - looking statements . Forward - looking statements are subject to certain risks, trends and uncertainties that could cause actual results to differ materially from those projected . Among those risks, trends and uncertainties are the ability of our project with Yima to produce earnings and pay dividends ; our ability to develop and expand business of the TSEC joint venture in the joint venture territory ; our ability to successfully partner our technology business ; our ability to develop our power business unit and marketing arrangement with GE and our other business verticals, including DRI steel, through our marketing arrangement with Midrex Technologies, and renewables ; our ability to successfully develop the SES licensing business ; the ability of the ZZ Joint Venture to retire existing facilities and equipment and build another SGT facility ; the ability of Batchfire management to successfully grow and develop Callide operations ; the economic conditions of countries where we are operating ; events or circumstances which result in an impairment of our assets ; our ability to reduce operating costs ; our ability to make distributions and repatriate earnings from our Chinese operations ; our ability to successfully commercialize our technology at a larger scale and higher pressures ; commodity prices, including in particular natural gas, crude oil, methanol and power, the availability and terms of financing ; our ability to obtain the necessary approvals and permits for future projects, our ability to raise additional capital, if any, our ability to estimate the sufficiency of existing capital resources ; the sufficiency of internal controls and procedures ; and our results of operations in countries outside of the U . S . , where we are continuing to pursue and develop projects . Although SES believes that in making such forward - looking statements our expectations are based upon reasonable assumptions, such statements may be influenced by factors that could cause actual outcomes and results to be materially different from those projected by us . SES cannot assure you that the assumptions upon which these statements are based will prove to have been correct . 2
