Item 1.01 Entry into a Material Definitive Agreement.

On June 27, 2025, a subsidiary (the “Borrower”) of enCore Energy Corp. (the “Company”) and Boss Energy Limited (“Boss”) entered into an Amendment No. 3 (the “Third Amendment”) to the Uranium Loan Agreement, dated December 5, 2023, as amended by Amendment No. 1 dated January 31, 2024 and Amendment No. 2, effective February 26, 2025 (as amended, the “Uranium Loan Agreement”) to extend the repayment date one week to July 3, 2025.

On July 2, 2025, the Borrower entered into a Fourth Amendment and Addendum to Uranium Loan Agreement with Boss (the “Fourth Amendment”) to, among other things, extend the loan repayment date of the Uranium Loan Agreement to December 27, 2025 (the “Repayment Date”) and provide for a cash facility of $3.6 million (the “Facility”) that may be drawn at any time prior to November 27, 2025 to fund the Borrower’s capital contributions to the joint venture between the Company and Boss at the Company’s Alta Mesa In Situ Recovery Uranium Project and Central Processing Plant in South Texas. The original Uranium Loan Agreement was for 200,000 pounds of uranium, valued at $20.1 million, which would be repayable to Boss in kind or cash based on the prevailing spot price at the time the loan was made. Since the original Uranium Loan Agreement was made, the Company has repaid $11.9 million and $10.4 million remains outstanding under the Uranium Loan Agreement as of the date of the Fourth Amendment.

Pursuant to the Amendment, the interest rate on borrowings under the Uranium Loan Agreement is increased to 10.00% per annum, and beginning August 1, 2025, the Borrower will also pay Boss monthly an amount equal to the average undrawn Facility amount during the preceding month multiplied by 2.0% per annum.

The Amendment also includes other conforming updates to the Uranium Loan Agreement to account for the Facility, which the Company considers customary for an agreement of this type, and adds the ability of Boss to require the Borrower immediately transfer membership interests representing control in the joint venture between the Company and Boss in an event of default under the Uranium Loan Agreement. The Uranium Loan Agreement is secured by the Borrower’s pledge of equity in the joint venture between the Company and Boss and is guaranteed by the Company.

The Uranium Loan Agreement, as amended, includes representations and warranties, affirmative and negative covenants and events of default that the Company considers customary for an agreement of this type, including related to its indebtedness and interests in the joint venture between the Company and Boss. Boss may terminate the Uranium Loan Agreement upon an event of default. The Uranium Loan Agreement cannot be redrawn upon once repaid.

This description of the material terms of the Third Amendment and the Fourth Amendment does not purport to be complete and is qualified in its entirety by reference to the Third Amendment and Fourth Amendment, which are filed as Exhibits 10.1 and 10.2 to this Current Report on Form 8-K and are hereby incorporated by reference into this Item 1.01.
