Caution about Forward-Looking Information

This website includes forward-looking information and statements within the meaning of applicable Canadian and U.S. securities laws. Actual results and events may be significantly different from what we currently expect. These statements are based on a number of material assumptions, which may prove to be incorrect. We recommend that you review our current annual information form, and our current annual and any subsequent quarterly management's discussion and analysis, for more information about these assumptions and risks. Forward-looking information is designed to help you understand management's current views of our near and longer-term prospects, and it may not be appropriate for other purposes. We will not necessarily update this information unless we are required to by securities laws.

Examples of forward-looking information in this website include: our strategy for increasing our future annual uranium production and supply levels; our expectations about future global uranium supply, consumption, demand and the number of operable reactors; future production levels at our fuel services operations; our expectations regarding future spot prices and our uranium price sensitivity analysis; our expectations regarding our future capital requirements and expenditures; the future outlook for each of our operating segments and our consolidated future outlook; the terms and volumes to be covered by our current and future long-term delivery contracts; future royalty and tax payments and rates; our mineral reserve and resource estimates; and our plans and expectations for each of our uranium operating properties, development projects and projects under evaluation, and fuel services operating sites.

The material risks that could cause actual results to vary include: actual sales volumes or market prices for any of our products or services are lower than we expect for any reason, including changes in market prices or loss of market share to a competitor; we are adversely affected by changes in foreign currency exchange rates, interest rates or tax rates; our production costs are higher than planned, or necessary supplies are not available, or not available on commercially reasonable terms; our estimates of production, purchases, costs, decommissioning or reclamation expenses, or are tax expense estimates, prove to be inaccurate; we are unable to enforce our legal rights under our existing agreements, permits or licences, or are subject to litigation or arbitration that has an adverse outcome; there are defects in, or challenges to, title to our properties; our mineral reserve and resource estimates are inaccurate, or we face unexpected or challenging geological, hydrological or mining conditions; we are affected by environmental, safety and regulatory risks, including increased regulatory burdens or delays; our forecasts relating to termination of uranium sales contracts with our customers prove to be inaccurate; we cannot obtain or maintain necessary permits or approvals from government authorities; we are affected by political risks in a developing country where we operate; we are affected by terrorism, sabotage, blockades, civil unrest, accident or a deterioration in political support for, or demand for, nuclear energy; we are impacted by changes in the regulation or public perception of the safety of nuclear power plants, which adversely affect the construction of new plants, the relicensing or existing plants and the demand for uranium; there are changes to government regulations or policies that adversely affect us, including tax and trade laws and policies; our uranium and conversion suppliers fail to fulfill delivery commitments; our Cigar Lake and McArthur River development, mining or production plans are delayed or do not succeed; we are affected by natural phenomena, including inclement weather, fire, flood and earthquakes; our operations are disrupted due to problems with our own or our customers' facilities, the unavailability of reagents, equipment, operating parts and supplies critical to production, equipment failure, lack of tailings capacity, labour shortages, labour relations issues, strikes or lockouts, underground floods, pitwall failure, cave-ins, ground movements, tailings dam failures, transportation disruptions or accidents, or other development and operating risks; or that closing conditions for an acquisition may not be satisfied in a timely manner, or at all.

We have made material assumptions regarding: sales and purchase volumes and prices for uranium, fuel services and electricity; the demand for uranium, the construction of new nuclear power plants and the relicensing of existing nuclear power plants not being adversely affected by changes in regulation or in the public perception of the safety of nuclear power plants; production level and production costs; spot prices and realized prices for uranium; uranium sales contract terminations; tax rates, foreign currency exchange rates and interest rates; decommissioning and reclamation expenses; the reliability of our mineral reserve and resource estimates; the geological, hydrological and other conditions at our mines; the success of our Cigar Lake and McArthur River development, mining and production plans; our ability to continue to supply our products and services in the expected quantities and at the expected times; our ability to comply with current and future environmental, safety and other regulatory requirements, and to obtain and maintain required regulatory approvals; our operations not being significantly disrupted as a result of political instability, nationalization, terrorism, sabotage, blockades, civil unrest, breakdown, natural disasters, governmental or political actions, litigation or arbitration proceedings, the unavailability of reagents, equipment, operating parts and supplies critical to production, labour shortages, labour relations issues, strikes or lockouts, underground floods, cave-ins, ground movements, tailings dam failure, lack of tailings capacity, transportation disruptions or accidents or other development or operating risks; and the closing conditions for acquisitions being satisfied within the expected timeframes.
