STAMFORD, Connecticut, August 20, 2026, 10:50 EDT — Webster’s share volume soared to 15 times its usual level as the Santander acquisition concluded, with the transaction closing at a final value of $78.09.
- Webster closed the session with 91.3 million shares traded, approximately 15 times higher than its three-month average volume.
- The value of the cash-and-stock offer stood at approximately $78.09, based on Santander’s U.S. share price at 10:50 EDT.
- Webster shareholders have become Santander shareholders, moving the investment thesis from merger arbitrage to integration performance.
Webster Financial Corporation NYSE:WBS closed its run as an independent stock, posting a 91.3 million-share trading surge. Banco Santander NYSE:SAN finalized the $12.2 billion deal on Thursday, per Connecticut-based reporting released after markets closed.
Webster’s turnover was nearly 15 times higher than its typical three-month average of 6.1 million shares. This suggests that the primary driver for Webster leading the U.S. most-active list is related to closing mechanics, rather than a new earnings report.
The investment calculation has shifted. Webster shareholders got $48.75 in cash plus 2.0548 Santander American depositary shares for every WBS share. Future returns are now linked to Santander, no longer to Webster’s old regional-bank valuation.

The agreement was set in February, yet a portion of the value stayed tied to the market. According to a filing with the Securities and Exchange Commission, the deal involves a $48.75 cash payout and an exchange ratio of 2.0548 ADS.
The merged U.S. bank launches with approximately $327 billion in assets, $185 billion in loans, and $172 billion in deposits. Santander anticipates the deal will increase group earnings per share by 7% to 8% by 2028.
| Integration targets | Company target | Investor test |
|---|---|---|
| Yearly cost reductions | $800 million | Implementation without deposit outflows |
| U.S. RoTE by 2028 | About 18% | Profit increase against integration expenses |
| Group EPS improvement by 2028 | 7%–8% | Realising synergies and funding charges |
| Return on invested capital | About 15% | Loan quality and revenue gains |
| Combined loan/deposit ratio | About 100% | Stability of deposits |
Santander’s investment thesis relies on Webster’s cost-efficient deposit base and commercial operations. The lender aims for $800 million in yearly cost reductions and seeks to achieve an 18% return on tangible equity in the U.S. by 2028.
Webster reported strong operating results going into the transaction. Deposits in the second quarter increased 6% from the prior year to $70.3 billion, with loans rising 7.8% to $57.9 billion. Adjusted earnings reached $1.60 per share.

Chief Financial Officer Neal Holland stated that Webster’s “returns and growth affirm the quality” of its franchise. However, net interest margin declined by 18 basis points, reaching 3.26%. This ongoing margin pressure highlights the relevance of Santander’s funding-cost argument. Webster Q2 release

Before closing, analyst targets tended to align closely with the agreed deal value, as the likelihood of the transaction overshadowed Webster’s independent prospects. With trading in the security ended, those recommendations are now largely obsolete.
Santander executive chair Ana Botín described the two lenders as “a perfect match” following the Federal Reserve’s approval of the deal. Clearance had previously been given by both the OCC and the European Central Bank. Santander approval release
Risks: Santander needs to keep Webster deposits and cut expenses. Credit losses, potential disruption for customers, system conversion and lower U.S. margins may push back the expected earnings boost.
The merger spread for previous Webster shareholders has now closed. The next notable development will be Santander’s integration updates, focusing on deposit retention, realized cost savings, and advancements toward its U.S. return objective for 2028.
