FORMER NATIONAL SECURITY & INTELLIGENCE ADVISOR JODY THOMAS NOMINATED TO ELECTRA BOARD OF DIRECTORS

Electra Battery Materials Corp. has nominated Jody Thomas to its board of directors.

Ms. Thomas brings a distinguished record of public service and leadership in Canada's national security and defence sectors. Most recently, she served as national security and intelligence adviser to the Prime Minister of Canada, where she provided strategic counsel on national security priorities and intelligence coordination at the highest levels of government. Prior to that, Ms. Thomas held senior leadership roles as deputy Minister of National Defence and commissioner of the Canadian Coast Guard. Her decades of experience in public administration, operational leadership and risk management will provide valuable perspective as Electra advances its strategic priorities across North America's critical minerals supply chain.

"Electra's vision to establish a secure and sustainable supply chain for critical minerals in North America resonates deeply with my experience with Canada's strategic priorities," said Ms. Thomas. "I am honoured to join the board at a time when Canada and its allies are focused on reducing vulnerabilities and fostering domestic capacity in key sectors. I look forward to contributing to Electra's next phase of growth and transformation."

"Jody's nomination comes at a defining moment for Electra," said Electra chief executive officer Trent Mell. "As we execute on our critical minerals strategy and supply chain development plans, the insights she brings from decades at the highest levels of national defence and intelligence will be invaluable. Her expertise in risk management, security and federal operations directly aligns with our mission to build a resilient, domestic supply chain for electric vehicle batteries in North America."

"Jody's nomination reinforces our commitment to governance excellence and long-term value creation for our shareholders," added John Pollesel, chair of Electra's board of directors. "Her depth of experience will support the board's oversight role as we work closely with management to execute Electra's restructuring and advance our critical minerals strategy."

A pioneer in Canadian defence history, Ms. Thomas joined the naval reserves at the age of 17 and became the first woman to serve aboard a Canadian military vessel. She holds a bachelor of arts from Carleton University and is widely recognized for her leadership in federal operations and national security strategy.

Ms. Thomas's nomination follows the recent appointments of David Stetson, former chief executive officer of Alpha Metallurgical Resources, and Gerard Hueber, retired Rear Admiral, U.S. Navy, further enhancing the strategic depth and operational expertise of Electra's board of directors at a pivotal moment in the company's evolution. Ms. Thomas will stand for election to the board of directors at Electra's annual general and special meeting of shareholders, scheduled for Oct. 15, 2025. If approved by shareholders, the reconstituted board will comprise seven directors with a broad range of expertise in strategy, capital markets, defence and industrial operations.
