Sustainable investment specialist Impax Asset Management has enjoyed net inflows of £1.4bn during a year which has seen "unprecedented concern globally about environmental issues".
Over 12 months to 30 September, the firm has increased assets under management (AUM) by 21% to £15.1bn thanks to strong inflows into the majority of its products, including segregated mandates.
The two months to the end of November saw additional net inflows of £500m, contributing to AUM rising to £15.7bn.
However, the majority of the inflows were taken in by the group's listed equities products, while fixed income, smart-beta and US equities saw net outflows of £251m over the period.
The group said flows into Pax World Funds, which it acquired along with Pax World Management in 2018, were also negative in aggregate over the period, but turned positive on a monthly basis by September.
Meanwhile, profit before tax jumped 29% to £18.9m, while revenue increased 12% to £73.7m. The total dividend for the year of 5.5p marks a 34% increase year-on-year, the group added.
Commenting on the results, chairman Keith Falconer said: "The last 12 months have seen unprecedented concern globally about environmental issues and rapidly expanding opportunities from the transition to a more sustainable economy.
"Against this backdrop it has been yet another strong year for Impax. The key investment strategies maintained their track record of out-performing global equity markets, AUM continues to increase and we see growing interest from investors in our broad product range."
CEO Ian Simm added: "The drivers behind the global economy's transition to a more sustainable model are only increasing and we remain ideally positioned to benefit from this.
"The solid foundations we've laid down over the last twenty years and the investments we have made in our business should support significant further growth for the company."
Commenting on the outlook for the coming year, Impax said it has "well-developed, detailed contingency plans" for Brexit, having established "an entity authorised in the EU27 as a UCITS management company and an Alternative Investment Fund Manager with ancillary MiFID permissions".
"This legal entity is domiciled in Ireland, enabling Impax to continue providing services to existing EU clients and develop future EU relationships," the firm said.
"In the event of the UK departing the EU on World Trade Organization (WTO) terms, it is expected that less than five percent of the group's assets would need to be managed from our Dublin office."
