Banco Santander has agreed to acquire Webster Financial Corporation, the parent company of Webster Bank, in a transaction valued at approximately $12.2 billion, as the Spanish lender moves to strengthen its retail and commercial banking presence in the United States.
The acquisition brings together Santander’s existing U.S. operations with Webster’s regional banking franchise in the northeastern United States, significantly increasing Santander’s scale in deposits and commercial lending.
Deal Terms and Timeline
Under the agreement, Webster shareholders will receive a combination of cash and Santander American Depositary Shares for each Webster share, valuing the company at around $75 per share. The transaction is expected to close in the second half of 2026, subject to regulatory clearances and shareholder approvals.
Once completed, Webster Financial will become a wholly owned subsidiary of Santander, while Webster Bank will continue operating within Santander’s U.S. banking structure during the integration phase.
Expanding Santander’s U.S. Footprint
Webster Bank is headquartered in Stamford, Connecticut, and operates a network of retail and commercial banking offices across Connecticut, Massachusetts, Rhode Island, and nearby markets. The acquisition significantly broadens Santander’s access to stable retail deposits and middle-market commercial clients in the region.
Following the transaction, Santander’s U.S. banking operations are expected to hold more than $320 billion in total assets, placing the group among the larger retail and commercial banking institutions operating in the country.
As part of the transition, John R. Ciulla, Chairman and Chief Executive Officer of Webster Financial, is expected to take on the role of Chief Executive Officer of Santander Bank, N.A., Santander’s primary U.S. banking subsidiary. Christiana Riley will continue as Chief Executive Officer of Santander Holdings USA and country head for Santander in the United States.
Santander stated that customers of both banks should not experience immediate changes to their accounts or branch services while the transaction is under regulatory review.
The deal marks a significant step in Santander’s efforts to build scale in traditional U.S. banking, complementing its existing strengths in consumer finance and auto lending. Webster’s deposit base and commercial banking operations are expected to support improved funding stability and operating efficiency.
Santander has indicated that the combined business is expected to deliver cost efficiencies over time and improve the group’s overall performance in the U.S. market.
Santander entered the U.S. banking market in the mid-2000s and has since expanded through a mix of retail banking, corporate banking, and consumer lending activities. Webster Financial, founded in 1935, has developed a regional banking model focused on commercial clients, healthcare-related financial services, and consumer banking.
The transaction will be reviewed by U.S. banking regulators and Webster shareholders. Both banks expect the acquisition to close by late 2026, with integration efforts continuing into the following year as systems and operations are aligned.
