Two Natixis Investment Managers affiliates, Mirova and Thematics Asset Management, have unveiled plans to merge, aiming to create a global leader in thematic investing with a strong responsible investment focus.

The strategic merger, expected to close in Q4 2025 subject to regulatory and procedural approvals, seeks to align both firms’ distinct yet complementary capabilities to deliver a unique proposition to investors.

The deal combines Mirova’s €32bn in assets, including €3.1bn in thematic strategies, with Thematics AM’s €3.1bn in assets spread across high-conviction themes such as AI and robotics, water, health, safety, and the subscription economy.

“By combining their skills, Mirova and Thematics AM would be able to offer a diversified range of thematic investment products to meet the varied needs of investors while adhering to high sustainability standards. This merger project aims to create a unique offering in the asset management market, combining innovation and positive impact,” a statement noted.

Philippe Setbon, chief executive officer of Natixis IM, said the merger fits within the firm’s Vision 2030 strategy. “By uniting the strengths of Mirova and Thematics AM, we aim to address the growing needs of our clients in an increasingly competitive market.”

Mirova’s CEO, Philippe Zaouati, said the union will strengthen the firm’s leadership in responsible investment. “By joining forces, we could expand our offering in listed markets, better meet our clients’ expectations, and strengthen our position […] This initiative perfectly aligns with our goal of doubling our assets by 2030 and increasing our positive impact on the environment and society.”

Thematics AM president and chief investment officer Karen Kharmandarian echoed this view, adding: “This strategic merger would enable us to offer enhanced collective expertise […] providing a range of innovative thematic products that address their concerns and the challenges of our time.”
