In a move that sends waves through the global asset management technology space, SS&C Technologies announced Monday it will acquire Calastone, the U.K.-based funds network giant, in a £766 million ($1.03 billion) all-cash transaction from private equity titan Carlyle.

The deal, subject to regulatory greenlights, is slated to close in Q4 2025 and positions SS&C as a more formidable force in providing automated, scalable solutions to the global investment ecosystem.

Building a Borderless Fund Infrastructure

Calastone, headquartered in London, connects over 4,500 clients across 57 countries and territories, enabling seamless investment transactions amounting to £250 billion monthly. From traditional fund services to cutting-edge digital investments, tokenized funds, and ETFs, the firm has become a cornerstone of financial infrastructure for asset and wealth managers.

“Calastone has built an impressive network and platform,” said Bill Stone, SS&C’s founder, chair and CEO. “Together, we will create a more connected, automated, and intelligent global fund ecosystem.”

The acquisition folds more than 250 Calastone employees into SS&C’s Global Investor & Distribution Solutions business unit, enhancing the company’s operational footprint in London, Luxembourg, Hong Kong, Taipei, Singapore, New York, and Sydney.

A Deal Anchored in Innovation and Global Reach

Founded to reduce friction and inefficiency in fund distribution, Calastone expanded under Carlyle’s wing since 2019, fortifying its product suite and expanding into high-growth regions.

“Joining forces with SS&C allows us to realize our shared ambition: building the most intelligent and connected operating model in the global funds industry,” said Julien Hammerson, CEO of Calastone.

“Under Julien’s leadership, Calastone’s network evolved into a truly differentiated, automated offering,” said Fernando Chueca, managing director of Carlyle Europe Technology Partners. “We’re confident SS&C will carry that legacy forward.”

The Legal Minds Behind the Mega-Merger

The transaction features heavyweight legal advisors:

• SS&C Technologies is advised by Davis Polk & Wardwell LLP, with partners Leonard Kreynin, Dominic Foulkes, Corey M. Goodman, Frank Azzopardi, and Matthew Yeowart leading the deal.

• Carlyle is advised by Linklaters and Mishcon De Reya LLP. Specific members of those legal teams were not disclosed at press time.

SS&C Sharpens Its Global Edge

This acquisition strengthens SS&C’s presence in global financial hubs while deepening its suite of offerings in the fast-evolving digitized fund ecosystem. With Wall Street eyeing blockchain, automation, and decentralized infrastructure, SS&C’s move to acquire Calastone is a strategic leap into the future of finance.
