Fiserv, Inc. (NYSE: FI), a global provider of payments and financial services technology, has announced a definitive agreement to acquire StoneCastle Cash Management, a company that facilitates stable deposit funding for depository institutions from thousands of businesses and enterprise customers.
This acquisition positions Fiserv to become a technology-enabled source of billions of dollars in institutional deposits, including those from Fiserv’s existing enterprise customers. The integration of StoneCastle’s insured deposit products alongside Fiserv’s core account processing, digital banking, payments, and cash-management capabilities is expected to help financial institutions strengthen their balance sheets.
Andrew Gelb, Head of Financial Solutions at Fiserv, stated, “Acquiring StoneCastle is an important step forward in our strategy to help financial institutions optimize their balance sheets, which will enable them to do more in the communities they serve.” Additionally, StoneCastle will provide integrated access to other contingent funding solutions for financial institutions. Takis Georgakopoulos, COO at Fiserv, further added that this move is expected to differentiate Fiserv in core banking by enabling institutions to custody cash supporting FIUSD stablecoins, unlocking new value and accelerating innovation across the financial ecosystem.
Founded in 2009 by StoneCastle Partners, LLC (SCP), StoneCastle Cash Management operates a leading deposit network in the U.
S. Its platform helps optimize individual, commercial, and governmental depositors while providing stable funding to over 1,000 FDIC-insured depository institutions. StoneCastle currently maintains an existing relationship with more than 300 Fiserv core banks within its larger deposit network and utilizes Finxact for ledger services supporting its emerging digital asset business.
Joshua Siegel, Founder & Chief Executive Officer of StoneCastle Partners, LLC, remarked, “For more than twenty years, StoneCastle has worked to connect institutional cash with community and regional banks in ways that promote safety, liquidity, and broader access to funding.” He also noted, “Joining Fiserv will accelerate our ability to innovate, expand our reach to financial institutions and depositors, and deliver even greater value through a unified, modern platform. We’re excited to pair our deposit funding expertise with Fiserv’s technology and client relationships.”
The transaction is projected to conclude by the first quarter of 2026, pending regulatory approvals and other customary closing conditions. Financial terms of the acquisition have not been publicly disclosed. Keefe, Bruyette & Woods, a Stifel Company, served as the exclusive financial advisor to StoneCastle Partners for the transaction.
