Summary
Janus Henderson Group announced on June 9, 2026, that it has entered into an agreement to acquire Rantum Capital, a Frankfurt-based alternative investment manager specializing in private debt and private equity. The acquisition positions Janus Henderson to deepen its presence in continental Europe's private credit market, a strategically important segment for institutional asset managers seeking diversification into higher-yielding alternative strategies.

Rantum Capital, acquired from its founders, currently manages €1.2 billion ($1.38 billion) across multiple strategies focused on financing solutions for family-owned and entrepreneur-backed small and mid-sized enterprises. The firm operates across Germany, Australia, and Switzerland, with particular strength in the German-speaking DACH region. According to Janus Henderson's statement, "Rantum Capital will play a central role in the build-out of the company's pan-European private credit platform" while also enhancing capabilities in private equity to complement the group's broader private markets strategy.

Ali Dibadj, chief executive officer of Janus Henderson, characterized the acquisition as reflective of the firm's strategic priorities: "it reflects our focus on diversifying into high-demand areas while also amplifying our existing strengths, including our institutional client relationships, to better support our clients' evolving needs." The transaction underscores intensifying competition among global asset managers to consolidate alternative investment platforms and capture growing institutional demand for private credit solutions in mid-market segments.

Janus Henderson reported $480 billion in assets under management as of March 2026. The deal carries an expected completion date in the third quarter of 2026, with deal valuation not disclosed. The acquisition expands the London-based asset manager's footprint in German-speaking Europe, a region with substantial mid-market financing demand and established relationships within the family office and entrepreneurial business communities that represent core target clients for private credit strategies.
