Aztec Group, a financial services company specialising in fund and corporate services for the alternative assets industry, has finalised its strategic partnership with Warburg Pincus.

Warburg Pincus, managing over $87bn in assets, has selected Aztec as a preferred provider for specific fund administration services worldwide.

The decision underscores Warburg Pincus’s confidence in Aztec’s growth potential and its commitment to delivering sustained value to clients.

The partnership comes after a year of exceptional performance for Aztec in the US, where the group has expanded its presence significantly.

Under the partnership, Warburg Pincus joins Aztec as a minority shareholder and an important client, enhancing the latter’s expansion, especially in the US market.

Aztec Group CEO Kathryn Purves said: “Our vision has always been clear: to deliver a truly premium service to private market clients, built on close relationships, technical strength and operational excellence.

“Partnering with Warburg Pincus brings together two organisations with shared ambition – our client-first culture and specialist expertise, and their global reach and experience backing high-growth businesses.

“This partnership enables us to scale with purpose, while staying true to what makes Aztec special: our people, our culture and our commitment to client service.”

Aztec’s growth in the US is supported by its extensive experience in back-office operations, fund accounting, investor services, and operational compliance.

As outsourcing becomes more common in the US, Aztec offers a proven, institutional-grade solution with its established track record and dedicated local teams.

The partnership with Warburg Pincus is expected to further strengthen Aztec’s position as a premium global partner to private markets clients.

Founded in 2001, Aztec is an independent provider of corporate services, employing over 2,000 individuals across the Channel Islands, Ireland, Luxembourg, the UK, and the US.

The group specialises in alternative investments, administering over $600bn in assets, 450 funds, and 4,500 entities across major asset classes.

Warburg Pincus Managing Director and Head of Europe Andrew Sibbald added: “We have been eagerly awaiting this moment since we announced our investment in Aztec some nine months ago.

“Our enthusiasm for the business and the market opportunity has only grown in the interim and we very much look forward to developing a strong partnership between our organisations, both as a substantial client and shareholder, over the coming years.

“We share management’s ambition for continued growth and the technological enhancement of Aztec’s proposition, together with their belief that excellent client service should remain at the heart of everything we do.”
