Calastone to be acquired by SS&C in £766 million deal

Fri, 25th Jul 2025

Calastone has entered into a definitive agreement to be acquired by SS&C Technologies in a transaction valued at £766 million, subject to regulatory approvals and expected to close in the fourth quarter of 2025.

The acquisition marks a notable development in the global funds and technology solutions sector, with Calastone set to become part of SS&C's Global Investor & Distribution Solutions division. This arrangement is designed to build on both firms' positions in the wealth and asset management industry, enhancing service delivery and operational efficiency.

Established in 2007, Calastone operates a large-scale transaction network for investment funds, connecting more than 4,500 financial organisations in 57 markets. The firm's technological infrastructure supports trading, settlement, and distribution operations for funds, enabling greater automation and efficiency.

The combination of Calastone's global network and SS&C's expertise in fund administration, transfer agency services, artificial intelligence, and automation is intended to provide a unified, real-time platform to the market. The companies aim to reduce costs, mitigate operational risks, and simplify processes across the global fund ecosystem. The integration is also expected to support improved investor servicing and operational scalability, thereby supporting asset and wealth managers as they adapt products and services for clients worldwide.

Julien Hammerson, Chief Executive Officer of Calastone, commented:

"This is a proud moment for everyone at Calastone. SS&C's global scale and deep expertise across fund services and technology will enable us to accelerate innovation and deliver new digital capabilities to the market. We look forward to working together to deliver transformational services to asset and wealth managers and drive growth. I am immensely grateful to the entire Calastone team for their dedication and to our clients for their continued trust."

Bill Stone, Chairman and Chief Executive Officer of SS&C Technologies, said:

"We are excited to welcome Julien the Calastone team and their valued clients to SS&C. Calastone has built an impressive network and platform, and together we will create a more connected, automated and intelligent global fund ecosystem. This combination reinforces our commitment to delivering innovative, scalable solutions to reduce complexity and enhance outcomes for the asset and wealth management industry".

The purchase follows Calastone's recent partnership with global investment firm The Carlyle Group, which acquired a majority stake in Calastone in 2020. During this period, Calastone has experienced growth and diversification, expanded its international operations, and invested notably in products targeting exchange-traded funds and digital investments, such as tokenisation.

Fernando Chueca, Managing Director on the Carlyle Europe Technology Partners investment advisory team, commented:

"We are pleased to have supported Calastone through such a transformational period of growth for the business. Its well-established technology network represents a differentiated, automated offering and we believe the business is well-positioned to build upon its market position and business momentum. We are confident that SS&C is the right partner to continue Calastone's success, and we look forward to watching the company thrive in its next phase."

Advisory roles for the transaction included Barclays as exclusive financial advisor to Calastone, while Linklaters and Mishcon De Reya served as legal advisors.
