On May 26, 2026, Webster Financial Corporation (the "Company") held a special meeting of its stockholders (the "Special Meeting") in connection with the proposed acquisition of the Company by Banco Santander, S.A. ("Banco Santander") in a cash and stock transaction (the "Transaction"), pursuant to that certain Transaction Agreement, dated as of February 3, 2026, by and among the Company, Banco Santander and a wholly owned subsidiary of the Company incorporated in the State of Virginia (the "Transaction Agreement"). There were 162,048,996 shares of common stock of the Company outstanding and entitled to vote as of the close of business on April 13, 2026, the record date for the Special Meeting. A total of 117,259,956 shares were present or represented by proxy at the meeting, representing 72.3% of all shares entitled to vote at the Special Meeting and which constituted a quorum. At the Special Meeting, the Company's stockholders voted on three proposals, each of which is described in the proxy statement of the Company, which also constitutes a prospectus of Banco Santander, filed with the U.S. Securities and Exchange Commission on April 23, 2026. The following is a brief description of each matter voted upon at the Special Meeting and the results of such voting, including the number of votes cast for or against each matter and the number of abstentions, tabulated by the Company's independent Inspector of Election with respect to each matter. All matters voted upon at the Special Meeting were approved by the Company's stockholders by the requisite vote.

#### Proposal 1 — Proposal to approve and adopt the Transaction Agreement and the transactions contemplated thereby (the "Transaction Proposal")
The Company's stockholders approved the Transaction Proposal as set forth below:

---

| | | |
|:---|:---|:---|
| **FOR** | **AGAINST** | **ABSTAIN** |
| 115788667 | 1279203 | 192086 |

---

**Proposal 2 — Proposal to approve, on an advisory (non-binding) basis, the compensation payments that will or may be paid to the Company's named executive officers in connection with the Transaction (the "Compensation Proposal")** 

The Company's stockholders approved, on an advisory (non-binding) basis, the Compensation Proposal as set forth below:

---

| | | |
|:---|:---|:---|
| **FOR** | **AGAINST** | **ABSTAIN** |
| 68045455 | 48130845 | 1083656 |

---

**Proposal 3 — Proposal to approve the adjournment or postponement of the Special Meeting, if necessary or appropriate, to solicit additional proxies if, immediately prior to such adjournment, there are not sufficient votes to approve the Transaction Proposal or to ensure that any supplement or amendment to the accompanying document is timely provided (the "Adjournment Proposal")** 

---

| | | |
|:---|:---|:---|
| **FOR** | **AGAINST** | **ABSTAIN** |
| 114010089 | 2963510 | 286357 |

---

Because there were sufficient votes to adopt the Transaction Proposal, no adjournment of the Special Meeting was determined to be necessary or appropriate, and accordingly, the Special Meeting was not adjourned and proceeded to conclusion.
