Electra Files Third Quarter 2025 Financial Reports

Press Release

Toronto, Ontario – (November 13, 2025) – Electra Battery Materials Corporation (NASDAQ: ELBM; TSX-V: ELBM) (“Electra” or the “Company”) announces the filing of its financial results for the third quarter ended September 30, 2025, including key activities supporting the Company’s focus on delivering its cobalt sulfate refinery in Temiskaming Shores, Ontario.

Progress during the quarter reflects Electra’s renewed momentum in establishing a North American battery materials supply chain. Alongside the Company’s significant financial accomplishments, recent strategic activities include feedstock testing from Ontario and Idaho, underpinning the long-term importance of domestic mineral assets and reinforcing Electra’s role in reducing North America’s reliance on foreign sources of critical battery materials.

Highlights:

• US$13 (C$17.5) Million Commitment from Ontario: On September 12, Electra signed a term sheet with the Ontario government to advance its cobalt refinery. The investment complements previously announced government backing, including a US$20 million award from the U.S. Department of Defense and a US$15 million (C$20 million) commitment from the Government of Canada, for aggregate US$48 million of government support.

• US$34.5 Million Financing Completed: In August 2025, the Company launched a US$34.5 million financing coinciding with a balance sheet restructuring, reducing the Company’s debt to approximately US$28 million and which is intended to provide the remaining financing for the refinery construction. Both transactions closed in October, subsequent to the quarter end. The oversubscribed private placement demonstrated market support for Electra’s long-term strategy and positioned the Company to resume construction and commissioning activities.

• Bench Strength Added to Board: The Company also augmented its Board of Directors during the quarter with the additions of David Stetson, a seasoned executive with over 20 years of experience in the energy and mining sectors; Gerard Hueber, a retired U.S. Navy Rear Admiral and former Raytheon executive; and Jody Thomas, Canada’s former National Security and Intelligence Advisor to the Prime Minister. Their appointments bring valuable expertise in operations, policy, and finance, and support strong governance and oversight as Electra transitions into execution.

• North American Feedstock Testing: In July, Electra commenced metallurgical testing of North American cobalt feedstock from two sources, its Iron Creek project in Idaho and legacy operations in the historic Cobalt Camp in Ontario. This program aims to validate the suitability of regional material for future refinery processing and further align Electra’s operations with its strategy of onshoring critical minerals supply.

Post-period Highlights:

• Advancement of U.S. Cobalt-Copper Assets: In October, the Company announced progress at its Iron Creek cobalt-copper project in Idaho, including continued geological modeling and evaluation to support future opportunities. These efforts strengthen Electra’s long-term vision of onshoring the North American supply chain.

• Appointment of VP, Projects & Engineering: On October 29, The Company announced the appointment of Paolo Toscano as Vice President, Projects and Engineering to lead the construction and commissioning of North America’s first cobalt sulfate refinery in Temiskaming Shores, Ontario, reinforcing Electra’s commitment to disciplined execution.

• Construction Reactivated at Refinery Project: With a US$82 million funding package arranged, Electra reactivated construction at its Ontario cobalt refinery in November 2025, building on its summer early works program completed in September.

“Our progress through the third quarter and beyond reflects the dedication of our team and a firm commitment to delivering on what we set out to do,” said Marty Rendall, CFO. “We have taken disciplined steps to strengthen our financial foundation, secured critical support to de-risk our project, and aligned our efforts around construction readiness. As we move forward, we remain focused on delivering North America’s first cobalt sulfate refinery and creating long-term value.”

As of September 30, 2025, the Company had a cash balance of C$3 million. Following quarter-end, on October 22, 2025, Electra closed a US$34.5 million equity financing and completed its previously announced balance sheet restructuring. With this financing, along with US$48 million in combined government support, Electra believes it is funded to complete construction and commissioning of its cobalt sulfate refinery in Ontario.
