Forward-looking statements are subject to risks, uncertainties and assumptions and are identified by words such as “expects,” “estimates,” “projects,” “anticipates,” “believes,” “could,” and other similar words. All statements addressing events or developments that WWR expects or anticipates will occur in the future, including but not limited to statements relating to the Company’s growth, developments at the Company’s projects, the future production of graphite, including on a pilot scale, and future sales of graphite, including as a first mover for key components of electrical storage devices, and the Company’s liquidity and cash demands, including future capital markets financing and disposition activities, are forward-looking statements.  Because they are forward-looking, they should be evaluated in light of important risk factors and uncertainties.  These risk factors and uncertainties include, but are not limited to, (a) the Company’s ability to successfully integrate AGC’s business into its own, and the risk that additional analysis of the Coosa Graphite Project may result in revisions to the findings of WWR’s initial optimization study; (b) the Company’s ability to raise additional capital in the future; (c) spot price and long-term contract price of graphite, uranium and lithium; (d) risks associated with our foreign and domestic operations; (e) operating conditions at the Company’s projects; (f) government and tribal regulation of the graphite industry, uranium industry, the lithium industry, and the power industry; (g) world-wide graphite, uranium and lithium supply and demand, including the supply and demand for lithium-based batteries; (h) maintaining sufficient financial assurance in the form of sufficiently collateralized surety instruments; (i) unanticipated geological, processing, regulatory and legal or other problems the Company may encounter in the jurisdictions where the Company operates or intends to operate, including in Alabama, Texas, New Mexico, Utah, Nevada and Republic of Turkey; (j) the ability of the Company to enter into and successfully close acquisitions or other material transactions, (k) the results of the Company’s lithium brine exploration activities at the Columbus Basin, Railroad Valley, and Sal Rica projects, and the possibility that future exploration results may be materially less promising than initial exploration result; (I) any graphite, lithium or uranium discoveries not being in high enough concentration to make it economic to extract the metals; and (m) other factors which are more fully described in the Company’s Annual Report on Form 10-K, Quarterly Reports on Form 10-Q, and other filings with the Securities and Exchange Commission. Should one or more of these risks or uncertainties materialize or should any of the Company’s underlying assumptions prove incorrect, actual results may vary materially from those currently anticipated.
