Ucore Rare Metals Inc. (TSX-V: UCU) (OTCQX: UURAF) is pleased to announce the exercise of warrants by Randy Johnson, a director of the Company, through his wholly owned holding company, Orca Holdings, LLC, resulting in Orca’s acquisition of 10,268,165 common shares of the Company. The Company also announces the early repayment of all indebtedness previously owing by the Company to Orca under certain debt arrangements.

The warrant exercises were completed on September 9, 2026 and resulted in the issuance of an aggregate of 10,268,165 Common Shares from treasury upon payment of the applicable exercise prices. The Company received aggregate proceeds of $8,485,123.75 from the exercise of the warrants.

The Company believes that the warrant exercises, which involved warrants that had expiry dates ranging from October 1, 2026 to January 31, 2027, reflects continued support for Ucore and its strategic objectives. The proceeds from the warrant exercises further strengthened the Company’s financial position and provide additional flexibility as it advances its business plan. Orca continues to hold the 10,268,165 Common Shares that were issued by the Company as a result of the recent warrant exercises.

In addition, Ucore confirms that on September 4, 2026, it repaid in full all outstanding principal and accrued interest owing to Orca under: (i) the Company’s secured line of credit facility maturing October 1, 2026 and bearing interest at 10.0% per annum; and (ii) the Company’s secured term loan maturing January 31, 2027 and bearing interest at 9.0% per annum. The total amount of principal and accrued interest that was repaid by the Company was $8,709,268 (US$6,274,463).

The repayment of these obligations reduces the Company’s outstanding liabilities and eliminates its indebtedness to Mr. Johnson and Orca. The Company currently has no outstanding loans or debt. “Retiring these debt obligations further strengthens Ucore’s balance sheet at an important point in the Company’s growth,” stated Pat Ryan, P.Eng., Chairman and CEO of Ucore. “We are entering the next stage of the Louisiana SMC’s development with greater financial flexibility and a clear focus on execution.”

The loans from Orca were not convertible into Common Shares and their repayment had no effect on Mr. Johnson’s ownership of, or control over, voting securities of the Company.

For additional information regarding the Orca 2023 Facility and the Orca Term Loan, see Note 6 (Loans Payable) to the Company’s unaudited interim condensed consolidated financial statements for the three and six-month periods ended June 30, 2026, available under the Company’s profile on SEDAR+ and filed on August 26, 2026. Copies of the related loan agreements were also filed under the Company’s profile on SEDAR+ as material contracts.

An early warning report will be filed by Mr. Johnson and Orca in accordance with applicable Canadian securities laws in connection with the warrant exercise. A copy of the early warning report will be available under the Company’s profile on SEDAR+ at www.sedarplus.ca.

The issuance of the Common Shares to Orca and the early repayment of the loans from Orca constituted a “related party transaction”, as such term is defined in Multilateral Instrument 61-101 – Protection of Minority Security Holders in Special Transactions, and may have required the Company to obtain minority shareholder approval and a formal valuation of the subject matter of the transactions, unless exemptions from such requirements were available. In completing the transactions, the Company relied on the exemptions from the formal valuation and minority shareholder approval requirements of MI 61-101 available under sections 5.5(a) and 5.7(1)(a), respectively, as the fair market value of the debt and interest that was repaid, and the fair market value of the Common Shares issued to Orca, did not exceed 25% of the Company’s market capitalization, as determined in accordance with MI 61-101.

The transactions described in this press release were approved by the Company’s board of directors not including Mr. Johnson. No special committee was established in connection with the transactions. The Company did not file a material change report in respect of the loan repayments more than 21 days before the dates of the transactions. In the Company’s view, the shorter period was reasonable and necessary in the circumstances to complete the transactions in an expeditious manner and improve the Company’s financial position by reducing the Company’s outstanding liabilities and interest expenses.
