Led by Léa Dunand-Chatellet, who became Chief Executive Officer on 1 July 2026, the new Executive Committee brings together complementary expertise across investments, business development, sustainable finance, strategy, transformation and corporate functions.

The new Executive Committee comprises:

• Léa Dunand-Chatellet, Chief Executive Officer
• Candice Brenet, Deputy CEO, Chief Strategy and Transformation Officer
• Laurence Willig, Deputy CEO, Chief Finance and Governance Officer
• Raphaël Lance, Chief Investment Officer, Private Assets
• Karen Kharmandarian, Chief Investment Officer, Listed Assets
• Alix Boisaubert, Chief Business Development Officer
• Mathilde Dufour, Chief Sustainability and Talent Officer

This strengthened governance structure is designed to sharpen execution, reinforce Mirova’s leadership and equip the firm for the opportunities and challenges shaping the future of sustainable finance. It builds on Mirova’s recognised expertise and the commitment of its highly experienced teams, which remain a key strength of the firm.

Alongside a leadership team deeply rooted in Mirova’s culture, investment conviction and expertise, Candice Brenet joined Mirova last week as Deputy CEO, bringing a complementary external perspective to the Executive Committee. Her extensive experience at leading financial institutions combines strategic and transformation expertise with deep knowledge of private markets.

ollowing the merger with Thematics Asset Management in January 2026, Karen Kharmandarian has been appointed Chief Investment Officer for Listed Assets. His appointment provides continuity of leadership across Mirova’s listed assets platform, while his extensive investment experience and deep knowledge of the firm’s thematic capabilities position him well to support its next stage of development. Hervé Guez will remain with Mirova until 30 September to ensure a smooth handover.

Together, Candice and Karen bring a complementary blend of strategic, transformational, and investment expertise that will further strengthen Mirova’s capabilities as the firm enters this new chapter.

“Mirova has built a unique position in sustainable finance by combining investment expertise with strong sustainability convictions, and I would like to take this opportunity to thank Hervé Guez for his instrumental contribution to Mirova’s creation and development. As our industry enters a new phase, our ambition is to build on these foundations while further strengthening our capabilities, our client focus and our ability to execute,” said Léa Dunand-Chatellet, Chief Executive Officer of Mirova.

“Sustainable finance is maturing rapidly, bringing new expectations from investors, new market dynamics and new opportunities to deliver impact at scale. By drawing on the depth of our internal talent and complementing it with new expertise where needed, we are positioning Mirova for its next stage of growth. Our ambition is clear: to reinforce Mirova’s role as a global leader in sustainable finance, leveraging the strength of our sustainability DNA and our complementary capabilities across both listed and private assets”, she added.

Leveraging its distinctive sustainability DNA and complementary capabilities across listed and private assets, Mirova remains fully committed to its mission, investment convictions, and long-term vision — and to its ambition of reinforcing its position as a global leader in sustainable finance, delivering investment solutions that support both long-term value creation and the transition to a more sustainable economy.
