This transition period provides time to make any changes needed to maintain FDIC coverage at the desired level. For more information on FDIC coverage and related considerations, visit: fdic.gov.

On February 3, 2026, Webster announced it entered an agreement to be acquired by Banco Santander (“Santander”). Webster shareholders approved the transaction on May 26, 2026, and the acquisition closed on August 20, 2026.

The consideration each Webster shareholder received for each share of their WBS stock was $48.75 in cash AND 2.0548 shares of Santander ordinary shares, with fractional shares paid in cash. WBS stockholders received Santander American Depository Shares (“ADS”) by default; ADS are priced and traded in US dollars on the New York Stock Exchange.

Webster has paid all declared dividends on its common stock (ordinary shares). Owners of Santander ordinary shares (including ADS) will receive dividends according to Santander’s dividend declarations (historically twice annually).

Webster's former Preferred Series F and Series G securities were transferred into newly created Santander Holdings USA Preferred Series H and Preferred Series I, respectively. The conversion occurred without any action required by the holder. The new series of Santander Holdings USA preferred stock have substantially the same terms as the Webster preferred stock.

Trading symbols may vary by brokerage or market information platform, so there is not a single universally displayed ticker symbol. In many cases, the securities may appear as a variation of SNUS-H or SNUS-I. If you are unable to locate the securities by ticker symbol, we recommend searching by CUSIP:

• Series H (formerly Webster Series F): CUSIP 80282K700
• Series I (formerly Webster Series G): CUSIP 80282K809

Prior to closing on August 20, 2026, the below dividends were declared on Webster’s preferred stock. The dividends on Webster’s preferred stock will be paid as declared to the holders of record for the equivalent series of Santander Holdings USA preferred stock on the applicable record date:

• Webster’s former series F preferred stock and Santander Holdings USA Series H preferred stock dividend is payable September 15, 2026, to shareholders of record on August 31, 2026.
• Webster’s former series G preferred stock and Santander Holdings USA Series I preferred stock dividend is payable October 15, 2026, to shareholders of record on September 30, 2026.

For your consideration, it was noted in the proxy statement (p. 73 as numbered) for the transaction that the consideration received by Webster shareholders from Santander was considered fully taxable to US taxpayers.

Individuals that own physical stock certificates of Webster shares will need to take action to convert their shares and receive the exchange consideration. They will receive a mailing from Citibank, N.A. with a Depositary Notice, a Letter of Transmittal and instructions for the surrender of their certificated shares and receipt of exchange consideration, and an informational letter regarding the International Direct Investment program available to Santander ADS holders.
