Janus Henderson reported $700 million (£533 million) in net inflows in the third quarter, taking group assets under management (AUM) to $360.5 billion.
The total client commitment was equivalent to a 5% increase in group funds.
The business said efforts to integrate the two historical wings of business since they were merged in May were progressing ahead of expectation.
Adjusting for acquisition costs, inc0me across the combined business stood at $114.2 million, 18% lower than $139.8 million in the second quarter. Revenue fell from $482 million in the second quarter to $454 million.
Dick Weil and Andrew Formica (pictured), co-chief executive officers of Janus Henderson Group, said: ‘Importantly, flows were driven by demand for a wide range of strategies across Janus Henderson’s equity, fixed income and alternative capabilities.
'We are encouraged by the levels of engagement, support and relationships developing with clients, globally.’
They added that the expansion of Janus Henderson’s strategic partnership to include BNP Paribas in the US would provide the firm with a global platform for growth.
‘Only five months have passed since the formation of Janus Henderson, yet pleasingly we are seeing green shoots in the cross-revenue opportunities, brought about by our global distribution footprint, expanded product set and collaborative culture.’
