By Vriti Gothi

SS&C Technologies Holdings, Inc. a investment and financial services software and solutions, has acquired Calastone, a technology solutions provider to the wealth and asset management sector.

The transaction, valued at approximately $1.03 billion, is subject to customary regulatory approvals and is anticipated to close in the fourth quarter of 2025.

This milestone marks a pivotal step in Calastone’s growth journey and reflects the enduring strength of its global network, market-leading technology, and trusted client partnerships developed over the past 17 years. Following completion, Calastone will become part of SS&C’s Global Investor & Distribution Solutions division, bringing together complementary capabilities to accelerate digital transformation and deliver greater scale, innovation, and efficiency across the wealth and asset management value chain.

Founded in 2007, Calastone operates the largest transaction network for investment funds worldwide, connecting more than 4,500 financial organisations across 57 markets. Its pioneering technology and infrastructure have redefined how firms automate and scale fund operations, driving significant efficiency gains across trading, settlement, and distribution processes.

This strategic combination will unite Calastone’s extensive global fund network with SS&C’s expertise in fund administration, transfer agency services, artificial intelligence, and intelligent automation. Together, the companies aim to deliver a unified, real-time operating platform designed to reduce cost, complexity, and operational risk while transforming distribution for the entire funds ecosystem. Clients will benefit from enhanced investor servicing, greater operational resilience, and the agility to innovate, diversify product offerings, and deliver better outcomes for investors worldwide.

Julien Hammerson, CEO of Calastone, said, “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 CEO 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 acquisition builds on Calastone’s successful partnership with The Carlyle Group, which acquired a majority stake in 2020. Under Carlyle’s backing, Calastone has accelerated its international expansion and broadened its technology suite, including advancing solutions for ETFs and digital investments through tokenisation.

Fernando Chueca, Managing Director at Carlyle Europe Technology Partners, said, “We are pleased to have supported Calastone through such a transformational period of growth. 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 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.”

Barclays acted as exclusive financial advisor to Calastone, with Linklaters and Mishcon De Reya providing legal counsel.
