TANTALUS SYSTEMS APPOINTS SUSANNA ZAGAR TO ITS BOARD OF DIRECTORS

Tantalus Systems Holding Inc. has appointed Susanna Zagar to its board of directors. Her addition expands and strengthens the skills and experience of Tantalus's board, particularly given her years of Canadian regulatory experience and energy sector leadership, and will serve to support Tantalus's growth across North America.

Ms. Zagar is an accomplished executive and governance professional who has shaped the Canadian energy landscape through her regulatory expertise, public policy advocacy and commitment to consumer protection. She currently serves as the president and chief executive officer of the Canadian Gas Association, whose members collectively meet nearly 40 per cent of Canadian energy needs.

Prior to joining the CGA, she led the largest independent economic energy regulator in North America, the Ontario Energy Board, where she had oversight of the generation, transmission and distribution of electricity and natural gas in Canada's most populous province. With past governance experience that spans the Institute of Public Administration of Canada (Toronto chapter chair) and the Canadian Centre for Occupational Health & Safety (board of governors), she currently chairs the audit and finance committee, and is a member of the board of governors of Ontario Tech University.

"We are excited to build on the leadership and expertise of our board of directors with the addition of Susanna Zagar," said Laura Formusa, chair of the Tantalus board. "Susanna brings with her a wealth of regulatory expertise, strategic industry insights and dynamic leadership skills. We look forward to her contributions as Tantalus continues to grow and serve its community of hundreds of utilities across North America."

Named as one of Canada's 100 most powerful women (WXN 2021), she also holds Institute of Corporate Directors (ICD.D) and Competent Boards, ESG (GCB.D), designations.
