DEAL OVERVIEW
Banco Santander
agreed to acquire all outstanding shares of Webster Financial for $75.00 per
share — comprising $48.75 in cash and 2.0548 Santander American Depositary
Shares. Based on Santander's closing share price on February 2, 2026, the
all-in value was approximately $75.59 per share, representing a 16% premium to
Webster's 10-day VWAP and a 9% premium to Webster's all-time high closing share
price. The implied equity value is approximately $12.2 billion ($12.3 billion
based on different reference dates).
Post-close,
Webster will become a wholly-owned subsidiary of Santander, merging into
Santander Bank N.A. Webster CEO John Ciulla will lead the combined Santander
Bank N.A. as CEO, with existing senior Webster executives remaining based in
Stamford — designated as a "key U.S. corporate location" under the
deal terms. The combined U.S. platform will have approximately $327B in assets,
$185B in loans, and $172B in deposits, positioning it among the top 10 U.S.
banks by assets.
"This transaction creates a more competitive bank with greater
scale and resources to serve our customers and communities. Together with
Santander, we will be better positioned to deliver exceptional service and
innovative solutions to individuals, families, and businesses across the
Northeast and beyond."
— John R.
Ciulla, CEO, Webster Financial
THE WEBSTER HSA BANK ADVANTAGE
HSA Bank —
Webster's health savings account subsidiary — is one of the most strategically
valuable assets in the deal. With 4.7 million HSA accounts and growing
deposits, HSA Bank provides Santander with a large, sticky, and fee-generating
deposit franchise that does not appear on most investors' radar. Health savings
accounts carry no interest rate sensitivity on the deposit side (employers
contribute fixed annual amounts) and generate durable fee income. For
Santander, integrating HSA Bank's national reach into its retail banking
platform dramatically diversifies its U.S. deposit base beyond the Northeast
geography.
