By Amit Chowdhry • Jul 21, 2025

SS&C Technologies has made a significant announcement regarding its plans to acquire Calastone, a prominent player in the financial technology space. As the world’s largest funds network, Calastone excels in providing innovative solutions for the wealth and asset management industries. This strategic deal, which is expected to enhance SS&C’s offerings in these sectors, comes with a substantial price tag of approximately £766 million, equivalent to about US $1.03 billion.

The agreement marks a pivotal moment in the financial technology landscape, further solidifying SS&C’s position in the market while enhancing Calastone’s capabilities and reach under Carlyle’s new ownership.

Calastone, based in London, operates the largest global funds network, linking over 4,500 financial organizations across 57 markets. The acquisition by SS&C is expected to close in Q4 2025, pending regulatory approvals. SS&C expects the deal to be earnings-accretive within 12 months and will finance it with a mix of debt and cash reserves. Calastone’s 250+ employees in London, Luxembourg, Hong Kong, and other locations will likely join SS&C’s Global Investor & Distribution Solutions team, led by General Manager Nick Wright.

This acquisition enhances SS&C’s commitment to transforming investment operations and expanding its geographic reach. By combining Calastone’s network and technology with SS&C’s strengths in fund administration and automation, the firms aim to create a unified, real-time platform that reduces costs and operational risks in the global fund ecosystem. This strategy will improve distribution, investor services, and operational efficiency, enabling asset and wealth managers to innovate and enhance outcomes for investors worldwide.
