Organigram Global Inc., the parent company of Organigram Inc., has named James Yamanaka as CEO, effective Jan . 15, 2026. 

Yamanaka will also join the company's board of directors when he assumes the role of CEO.

Yamanaka is a seasoned executive, having spent more than 20 years at British American Tobacco, with experience in strategy and general management across Europe and Asia. He succeeds Beena Goldenberg, who retired from the role of CEO in November.

As global head of strategy at British American Tobacco, Yamanaka was instrumental in developing the group strategy. Prior to his role as global head of strategy, he served as area director for North Asia (Japan and South Korea), where he achieved record market share in Japan. Before his role in Asia, Yamanaka transformed British American Tobacco’s Northern Europe Area from a traditional business into one positioned for sustainable growth through the acquisition of a nicotine pouch business.

Peter Amirault, current board chairman, has been appointed to serve as interim executive chair to oversee day-to-day management until Yamanaka fully assumes the CEO role. During this period, Geoff Machum, chair of the board’s Governance, Nominating and Sustainability Committee, will serve as the independent lead director. 

“We are excited to have James join the Organigram team,” Amirault said. “James’ history of driving strong international growth aligns perfectly with Organigram’s global aspirations. His experience in building high-performing teams and delivering results will be invaluable as we expand our international presence.”

Yamanaka holds a bachelor’s degree in political science and economics from UC San Diego, a master’s degree in foreign service from Georgetown University, and an MBA from London Business School. He will be based in Toronto, Ontario. He will assume the role as CEO of Organigram following completion of required procedures including customary immigration matters.

“I am thrilled to take on this new challenge,” Yamanaka said. “I have watched Organigram evolve into Canada’s number one recreational cannabis company by market share and believe it is well positioned to become a global leader in the cannabis industry. I look forward to building an international presence on Organigram’s strong foundation of high-quality products, trusted brands and a commitment to industry-leading innovation.”
