The firm also made targeted investments to support its growth and expanded its distribution capabilities, establishing a new office in Tokyo to strengthen its presence in North America, Latin America, and Japan.
Impax said it enhanced its product pipeline by launching an equities strategy targeting sustainable infrastructure and made additional investments to expand its fixed-income offering.
The company said it was also focused on increasing operational resilience and efficiency through investments in systems and infrastructure.
Impax introduced the Impax Sustainability Centre to support its sustainability initiatives further and facilitate the scaling of resources in the area.
“We made good progress in developing and launching new products, including a new sustainable infrastructure strategy and will soon launch a new social thematic strategy,” said chief executive officer Ian Simm.
“We have also identified a particular opportunity within fixed income and have made strategic hires into that team.
“We are reviewing opportunities to source additional fixed income capabilities and will provide an update in due course.”
Simm said that in a year when the firm celebrated its 25th anniversary, its conviction in its investment thesis focused on the transition to a more sustainable economy was stronger than ever.
“With valuations increasingly attractive, our investment teams have identified several compelling themes that we believe will play out over the medium to long term.
“For example, the adoption of renewable energy, the provision of climate resilient water supply and infrastructure and the deployment of new technology to improve access to healthy food and financial services worldwide.”
