The Notes will not be guaranteed by any of our subsidiaries, including the Bank, which is our principal subsidiary. The Notes will be effectively subordinated to our future secured indebtedness to the extent of the value of the assets securing such indebtedness and structurally subordinated to the existing and future liabilities of our subsidiaries, including without limitation the Bank’s depositors, liabilities to general creditors and liabilities arising in the ordinary course of business or otherwise, which means that such creditors generally will be paid from those subsidiaries’ assets before holders of the Notes would have any claims to those assets. The Indenture and the Notes do not limit the amount of Senior Indebtedness, secured indebtedness or other liabilities having priority over, or ranking equally with, the Notes that we or our subsidiaries may hereafter incur. As of June 30, 2025, on a consolidated basis, our liabilities totaled approximately $72.6 billion, which includes approximately $0.6 billion of subordinated notes of the Company that would rank equal with the Notes and $72.1 billion of liabilities of our subsidiaries that would be structurally senior to the Notes. “Senior Indebtedness” means, without duplication, the principal, premium, if any, unpaid interest (including interest accruing on or after the filing of any petition in bankruptcy or for reorganization relating to Webster, whether or not a claim for post-filing interest is allowed in such proceeding), fees, charges, expenses, reimbursement and indemnification obligations, and all other amounts payable under or in respect of the following indebtedness of Webster, whether any such indebtedness exists as of the date of the Indenture or is created, incurred or assumed after such date:

| • |     | all obligations for borrowed money; |

| • |     | all obligations evidenced by debentures, debt securities or other similar instruments; |

| • |     | all obligations in respect of letters of credit, security purchase facilities or bankers acceptances or similar 
 instruments (or reimbursement obligations with respect thereto);                                                |

| • |     | all obligations to pay the deferred purchase price of property or services, except trade accounts payable arising 
 in the ordinary course of business;                                                                               |

| • |     | indebtedness secured by any mortgage, pledge, lien, charge, encumbrance or any security interest existing on 
 property owned by Webster;                                                                                   |

| • |     | obligations associated with derivative products including, but not limited to, interest
