Global asset manager Janus Henderson Investors is set to nearly double its Australian funds under management through a series of acquisitions that include Antares Equities and Fairview Equity Partners.

The moves create a combined Australian business valued at $66 billion, marking a significant expansion of the firm's footprint in the region.

The acquisitions signal a strategic pivot for Janus Henderson, which is returning to active equity investing in Australia after several years of absence from the segment.

By acquiring these local firms, the global manager aims to bolster its capabilities in Australian equities and strengthen its overall position in the market.

This expansion comes as competition intensifies among asset managers vying for share in the Australian wealth management sector.

The deal structure allows Janus Henderson to rapidly scale its local presence without building capabilities from scratch, leveraging the existing client bases and investment teams of the acquired firms.
