American software services provider SS&C Technologies is set to acquire global funds network Calastone in a deal estimated to be approximately £766 million, with the transaction expected to close in Q4 of 2025.
Calastone, serving over 4,500 financial organisations in 57 markets, will become part of SS&C’s global investor and distribution solutions division. The integration, subject to regulatory approval, aims to accelerate innovation and improve operational efficiency across the wealth and asset management landscape.
Calastone’s global fund network will strengthen SS&C’s capabilities in fund administration, transfer agency and AI-driven automation. Together, the firms plan to build a unified, real-time platform aimed at reducing cost and complexity across fund operations. SS&C said the deal will enhance distribution, investor servicing and scalability, helping asset and wealth managers innovate and deliver better outcomes for clients.
The move follows Calastone’s 2020 partnership with The Carlyle Group, which acquired a majority stake and supported the firm’s expansion efforts. In recent years, Calastone has broadened its offering to include ETF processing and digital asset infrastructure through tokenisation initiatives.

“This is a proud moment for everyone at Calastone,” said Julien Hammerson, Calastone CEO. “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.”
“We are excited to welcome Julien, the Calastone team and their valued clients to SS&C,” said Bill Stone, chairman and CEO of SS&C Technologies. “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.”
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 welll-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.”
