## Exhibit 99.1

**Exhibit 99.1**![LOGO](g101831g0204030405438.jpg)

**WEBSTER FINANCIAL CORPORATION ENTERS INTO MERGER AGREEMENT WITH BANCO SANTANDER,** 

**S.A. FOR $12.3 BILLION** 

***• Creates Top Ten Retail and Commercial Bank by Assets Nationwide*** 

***• Establishes Top Five Bank by Deposits in the Northeast*** 

***Transaction Provides Compelling Value for Webster Stockholders*** 

Webster Financial Corporation (NYSE: WBS), the holding company for Webster Bank, N.A., today announced the signing of a definitive agreement under which Banco Santander, S.A. ("Santander") (NYSE: SAN, Madrid: SAN) will acquire Webster in a cash-and-stock transaction. Under the terms of the agreement, Webster stockholders will receive $48.75 in cash and 2.0548 Santander American Depository Shares for each Webster common share. Based on Santander's closing stock price on Monday, February 2, 2026, the transaction has an aggregate value of approximately $12.3 billion.

The per share consideration of $75.59 is based on closing prices as of February 2, 2026 and represents a 16% premium to Webster's 10-day volume-weighted average stock price, a 9% premium to Webster's all-time high closing stock price, and is greater than 2.0x Webster's fourth quarter 2025 period-end tangible book value per share.

"This is an exciting combination that brings together complementary strengths and a shared commitment to excellence," said John R. Ciulla, Chairman & CEO of Webster. "As a larger organization, we will unlock greater scale, broader capabilities and new opportunities for growth—while remaining deeply focused on the people who define our success. I look forward to joining the Santander team and enhancing our ability to support our clients. As a Connecticut-based bank with deep roots in the region, we also look forward to continuing our commitment to the communities we serve."

Mr. Ciulla continued, "Paramount to Webster's board and me was partnering with an organization that understands the importance and power of legacy as we do and the value we place on our clients. We found that shared commitment in Santander and are confident this transaction will create an even stronger partner to help our clients achieve their financial goals.

Ana Botín, Executive Chair of Banco Santander said, "This is an exciting step forward for Santander Group, as it creates a stronger bank for our customers and the communities we serve. Webster is one of the most efficient and profitable banks among its peers and bringing together two highly complementary franchises will expand the products, technology and capabilities we can deliver, with clear revenue opportunities from a stronger, more capable combined franchise.

This transaction is strategically significant for our U.S. business, while remaining a bolt-on for the overall Group. It allows us to strengthen our franchise in both scale and profitability in the U.S.

Importantly, we can achieve this while maintaining all our shareholder remuneration commitments, including the €5 billion share buyback we launched today and our broader distribution commitments.

------

The transaction delivers meaningful, tangible value for the Group and our shareholders. The consideration is based on a balanced mix of cash and stock which enhances EPS accretion for Santander shareholders while also allowing Webster shareholders to benefit in the combined upside.

This value creation is supported by combined cost savings—including delivery of our Santander U.S. organic plan—together with clear revenue opportunities from a stronger, more capable combined franchise.

Webster also brings a top-notch and proven management team, led by John Ciulla, which de-risks integration and accelerates execution from day one, with Christiana Riley continuing as Country Head for the US and Tim Ryan as Chair."

Under the terms of the definitive agreement, which has been unanimously approved by the board of directors of Webster and the relevant bodies of Santander, Webster will become a wholly-owned subsidiary of Santander. Once the transaction is completed, Christiana Riley will remain Santander's country head in the U.S. and the Chief Executive Officer of Santander Holdings USA ("SHUSA"). Ciulla will be the CEO of Santander Bank NA ("SBNA") into which all of Webster's businesses will be integrated. Luis Massiani, Webster's President and Chief Operating Officer, will be COO of both SHUSA and SBNA with responsibility for leading the integration, reporting to both Ms. Riley and Mr. Ciulla. This will ensure continuity of leadership and strong alignment with clients, colleagues, communities and regulators.

Mr. Ciulla and Mr. Massiani will both continue to be based in Webster's existing headquarters in Stamford, Connecticut, which will be a core corporate office for Santander, alongside its existing corporate offices in Boston, New York, Miami and Dallas.

Mr. Ciulla and Mr. Massiani, along with two additional current directors of Webster, will join the boards of directors of both SHUSA and SBNA. Tim Ryan will continue to chair the boards of directors of both SHUSA and SBNA.

The transaction is subject to customary closing conditions, including necessary bank regulatory approvals in the U.S. and EU and the approval of the stockholders of both Webster and Santander. The transaction is expected to close in the second half of 2026.

J.P. Morgan Securities LLC is serving as lead financial advisor and rendered a fairness opinion to Webster and Wachtell, Lipton, Rosen & Katz is serving as legal advisor. Piper Sandler & Co. also served as financial advisor to Webster.
