Industry Leader David Stetson Joins Electra Board of Directors

Press Release

Toronto, Ontario – (August 25, 2025) – Electra Battery Materials Corporation (NASDAQ: ELBM; TSX-V: ELBM) (“Electra” or the “Company”) is pleased to announce the appointment of David Stetson to its Board of Directors. Mr. Stetson is a seasoned executive with decades of leadership experience in the natural resources sector, including 14 years as a CEO.

During his tenure as CEO of Alpha Metallurgical Resources, the company’s market capitalization increased from $50 million to more than US$4 billion. He led the company through a complex restructuring, eliminated US$800 million of debt and transitioned to Chairman until his retirement in late 2024.

More recently he served on the board of Mallinckrodt Pharmaceuticals and chaired the Compliance and Corporate Governance Committee and served on the Transaction Committee. He played a significant role in helping the company reduce its indebtedness and complete its merger with Endo Pharmaceuticals.

Mr. Stetson brings a distinguished track record of driving operational improvements, building resilient organizations, and creating value for shareholders. He earned a Bachelor of Science degree from Murray State University, a juris doctorate from the Brandeis School of Law at the University of Louisville, and a Master of Business Administration degree from the University of Notre Dame.

“On behalf of the Board, I am delighted to welcome David to Electra,” said John Pollesel, Chair of Electra’s Board. “His proven expertise in guiding companies through expansion and delivering sustainable, long-term value will be instrumental as we bolster our financial foundation and deepen Electra’s role in North America’s critical minerals supply chain.”

“David’s appointment marks an important step forward for Electra as we strengthen our balance sheet and sharpen our focus on core operations,” said Electra CEO, Trent Mell. “His track record of building strong, resilient companies, together with his industry leadership, strategic insight, and ability to develop and mentor high-performing teams, will be a tremendous asset as we advance our strategy and position Electra for long-term growth.”

“I am thrilled to join Trent and the team at Electra at such a pivotal time for the Company,” said Mr. Stetson. “Electra is uniquely positioned to advance North America’s critical mineral priorities by building secure, domestic supply chains that are essential to both the energy transition and national security. I look forward to working alongside my fellow directors and Electra’s leadership to build on the strong foundation already in place and create lasting value for all stakeholders.”

Electra’s appointment of Mr. Stetson comes following the recently announced recapitalization process with the holders of the Company’s senior secured convertible notes (the “Lenders”), designed to strengthen the Company’s balance sheet and provide a more stable financial foundation (see August 21, 2025 press release). This process, which includes new financing arrangements to support operations and strategic initiatives and a significant reduction in the Company’s debt profile, marks an important step toward positioning Electra for long-term success.

Company Update

The Company also announces the closing of its previously disclosed bridge financing (the “Bridge Financing”) to support operations during the Company’s restructuring and recapitalization with the Lenders. Pursuant to the Bridge Financing, the Lenders have purchased an aggregate principal amount of US$2 million of unsecured 90-day 12.00% promissory notes (the “Bridge Notes”). Mr. Stetson is a board nominee of the Lenders pursuant to the Bridge Financing, however the addition of Mr. Stetson to the Board also reinforces Electra’s ongoing commitment to disciplined execution as the Company advances on its path of transformation and growth. Details of the Bridge Notes are available in the Company’s August 21, 2025 press release.
