Concentration Risk, Supplier | Concentrations of Supply Risk and Other Considerations with the War in UkraineThe current war in Ukraine has led to the U.S., Russia and other countries imposing sanctions and other measures that restrict international trade, including the Import Ban Act and the Russian Decree. The situation is rapidly changing, and it is not possible to predict future actions that could be taken.In May 2024, the U.S. passed the Import Ban Act that bans imports of LEU from Russia into the U.S., subject to the issuance of waivers by the DOE. Centrus has received two waivers from the DOE authorizing the importation of Russian LEU committed for delivery to our U.S. customers in 2024 and 2025 and authorizing the importation of Russia for processing and reexport to our foreign customers in 2025. On December 11, 2024, the Company filed a third waiver request application to allow for importation of LEU from Russia in 2026 and 2027 for use in future sales to our U.S. customers. On November 14, 2024, Russia passed the Russian Decree, effective through December 31, 2025, that rescinded TENEX’s general license to export LEU to the United States or to entities registered in the United States. Beginning in November 2024, TENEX was required to obtain a specific export license from the Russian authorities in order for it to make each of the remaining 2024 and 2025 shipments of LEU to Centrus and for shipments to Centrus in 2025. Centrus has been informed that TENEX has received three specific licenses to date which allow TENEX to export LEU to the U.S. for our pending orders. Centrus will use the majority of this LEU to satisfy pending orders to a single customer on a delayed basis in reliance on our contractual rights. TENEX has informed Centrus of its plan to seek additional export licenses to meet its delivery obligations under the TENEX Supply Contract for our other pending and future orders. However, Centrus has been informed that there is no certainty whether such licenses will be issued by the Russian authorities and if issued, whether they will be issued in a timely manner or rescinded prior to the shipment taking place. Canada has imposed sanctions on ocean transportation of Russian LEU, but has given a permit to the Company’s carrier that extends to March 2027. Additional sanctions or other restrictions 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 restrictions 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. In response to these bans and potential future bans or restrictions 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, to the extent within the Company’s control, the Company will seek additional licenses, waivers or other approvals 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 licenses, waivers, or approvals 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 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 2025-2027 for deliveries to U.S. customers. The Company has contracts and prospects for alternative sources that it expects to use 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.
