Amendment to Senior Secured Credit Facility

Electra Battery Materials Corporation announced an amendment to its Credit and Guaranty Agreement dated October 22, 2025. The amendment provides additional flexibility for working capital and government financing initiatives, supporting the company's ability to finalize government funding arrangements. Key changes include increased capacity to incur permitted indebtedness and greater flexibility to grant liens and make payments related to such indebtedness, specifically for government financing arrangements. These new permitted indebtedness and liens will be on a pari passu basis with existing secured lenders. All existing guarantees, security, and obligations under the Credit Agreement remain in full force and have been reaffirmed. The amendment aims to enhance the company's financial flexibility and support its strategic objectives in advancing North America's critical minerals supply chain.
