Concentration Risk, Supplier | Concentrations of Supply Risk and Other Considerations with the War in Ukraine The current war in Ukraine has led to the U.S., Russia and other countries imposing sanctions and other measures that restrict international trade. The situation is rapidly changing, and it is not possible to predict future actions that could be taken. The Company has multiple sources of supply; however, the supply contract with TENEX remains the Company’s largest source and accounts for well over one-half of or its anticipated supply in 2024-2027 for deliveries to U.S. customers. At present, sanctions have not impacted the ability of the Company or TENEX to perform under the TENEX Supply Contract. Recently, sanctions have been imposed by the U.S. on exports of fossil fuels. Russia has imposed sanctions on the export of commodities but does not include the export of LEU. Canada has imposed sanctions on ocean transportation of Russian LEU, but has given a permit to the Company’s carrier that extends to early July 2024. Additional sanctions or other measures by the U.S. or foreign governments (including the Russian government) could be imposed or the existing Canadian permit might not be extended. Any sanctions or measures directed at trade in LEU from Russia or the parties involved in such trade or otherwise, including denial or non-renewal of licenses or permits, could interfere with, or prevent, implementation of the TENEX Supply Contract. While the initial sanctions announced do not affect the ability of the Company or TENEX to implement the TENEX Supply Contract, the situation at this time is unpredictable and there are proposals in Congress (including one that has passed the House of Representatives) to impose a ban on imports of Russian LEU. If a ban were enacted or measures were taken to limit the supply of Russian LEU or to prohibit or limit dealings with Russian entities, including, but not limited to, TENEX or Rosatom, the Company would seek a license, waiver or other approval from the government imposing such measures to ensure that the Company could continue to fulfill its purchase and sales obligations. There is no assurance that such a license, waiver, or approval would be granted. If a license, waiver or approval were not granted, the Company would need to look to alternative sources of LEU to replace the LEU that it could not procure from TENEX. The Company has contracts for alternative sources that could be used to mitigate a portion of the near term impacts. However, the Company’s alternative sources are not sufficient to replace all of the Russian LEU the Company is currently permitted to import under the RSA, and to the extent additional supply cannot be obtained, or obtained at a higher costs, it will have a material adverse impact on its business, results of operations, and competitive position.Given the foregoing, there is no assurance that future developments would not have a material adverse effect on the Company’s procurement, payment, delivery or sale of LEU under the TENEX Supply Contract and well as on our business, results of operations, and competitive position.
