All statements, other than statements of historical fact, that address activities, events or developments that Etrion believes, expects or anticipates will or may occur in the future (including, without limitation, statements relating to the anticipated production from the Mito project and the anticipated development of the Company’s Japanese pipeline projects). This forward-looking information reflects the current expectations or beliefs of Etrion based on information currently available to it as well as certain assumptions (including that all necessary financing and regulatory or other approvals will be obtained as and when required and that current and future solar projects will be developed and operated in a manner consistent with the expectations of the Company). Forward-looking information is subject to a number of significant risks and uncertainties and other factors that may cause actual results to differ materially from those discussed in the forward-looking information, and even if such actual results are realized or substantially realized, there can be no assurance that they will have the expected consequences to, or effects on, Etrion. Factors that could cause actual results or events to differ materially from current expectations include, but are not limited to, the failure of the Mito project to operate as expected and the inability of the Company to obtain the necessary financing and approvals to advance the Japanese development pipeline as anticipated.
