SS&C Technologies Holdings has acquired global funds network and wealth management technology solutions provider Calastone for approximately £766m.

Calastone said the acquisition, which is subject to regulatory approvals and expected to close in the fourth quarter of 2025, represented a significant milestone and an endorsement of the firm’s network, technology, and client relationships.

Upon completion of the deal, Calastone will operate as part of SS&C’s Global Investor & Distribution Solutions division.

It said that this would enable the combined group to further scale innovation, service delivery, and operational efficiency across the global wealth and asset management landscape.

Barclays served as exclusive financial adviser to Calastone on the deal, while Linklaters and Mishcon De Reya provided the firm with legal advice.

Calastone was founded in 2007 and operates the world's largest transaction network for investment funds, connecting more than 4,500 financial organisations across 57 markets.

The firms said that Calastone’s fund network and technology would complement SS&C’s fund administration, transfer agency services, AI and intelligence automation capabilities.

The acquisition will see the companies combine their capabilities to deliver a unified, real-time operating platform that aims to reduce cost, complexity, and operational risk across the global fund landscape.

They argued that this strategic alignment would enable enhanced distribution, investor servicing, and operational scalability, which would empower wealth and asset managers to innovate, diversify products, and deliver better outcomes for investors.

“This is a proud moment for everyone at Calastone,” commented Calastone CEO, Julien Hammerson.

“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.”

Also commenting on the transaction, SS&C Technologies chair and CEO, Bill Stone, 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 Carlyle Group acquired a majority stake in Calastone in 2020, and Carlyle Europe Technology Partners investment advisory team managing director, Fernando Chueca, said: “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.”
