(a) None.

(b) The following provides a description of Rule 10b5-1 trading arrangements (as defined in Item 408 of Regulation S-K under the Exchange Act) adopted during the three months ended December 31, 2024, by any director or executive officer who is subject to the filing requirements of Section 16 of the Exchange Act:

On November 21, 2024, René F. Jones, Chairman and Chief Executive Officer, adopted a trading arrangement intended to satisfy the affirmative defense conditions of Rule 10b5-1(c). The arrangement will terminate on or before December 31, 2025. Under the arrangement, a maximum aggregate number of 144,022 vested stock options may be exercised, and the underlying shares will be held by Mr. Jones after the withholding of shares to cover the cost of the exercise price of the options and tax obligations (also known as a net exercise and hold settlement). The arrangement does not provide for the sale of shares. Transactions under the trading arrangement will not commence until completion of the required cooling off period under Rule 10b5-1.

No directors or executive officers terminated or modified a Rule 10b5-1 trading arrangement in the three months ended December 31, 2024.

Certain of the Company's directors or executive officers have made elections and are participating in the Company's tax-qualified 401(k) plan and nonqualified deferred compensation plans, or have made, and may from time to time make, elections to reinvest dividends in M&T Bank Corporation common stock, or have shares withheld to cover withholding taxes upon the vesting of equity awards or to pay the exercise price of options, each of which may be designed to satisfy the affirmative defense conditions of Rule 10b5-1 under the Exchange Act or may constitute non-Rule 10b5-1 trading arrangements (as defined in Item 408(c) of Regulation S-K).
