On Thursday 2 July 2026, Arendt Investor Services (AIS) announced the completion of its acquisition by BlackFin Capital Partners, following regulatory approval by the Commission de Surveillance du Secteur Financier (CSSF).
According to AIS, this marks the start of a new phase in the company's development with an ambition to accelerate its growth through international expansion and selective acquisitions, while further investing in technology, including artificial intelligence (AI), and enhancing its service offering.
Founded by the partners of Arendt & Medernach, AIS is Arendt's corporate and investor services company, established in 2009. It said it will continue to operate with the same teams, the same service model and in close cooperation with Arendt, which remains a “significant” minority shareholder.
Claude Niedner and Jean-Marc Ueberecken will remain on the Board alongside BlackFin representatives, ensuring continuity in the company's governance, while the AIS senior management team will also remain unchanged.
AIS described BlackFin as an experienced investor with a strong track record in building and scaling asset servicing platforms across Europe, as well as extensive sector expertise and an established international network. Founded in 2009, BlackFin is a private equity platform dedicated to financial services companies in Europe, with more than €4 billion in assets under management.
"As we embark on this next chapter with BlackFin, we are building on these foundations. We will preserve what made AIS successful while adding new dimensions – greater technological capabilities, stronger commercial reach and a more international footprint," said Christian Heinen, CEO of AIS.
"We are delighted to complete this transaction and begin this new chapter alongside the AIS management team. Our ambition is to support the company's continued growth by investing in technology, expanding its international reach and pursuing selective acquisition opportunities, while preserving the client focus and entrepreneurial culture that have made AIS such a success," added Eric May, Founding Partner at BlackFin Capital Partners.
