Material Event (Form 8-K)

On February 26, 2026, The Bank of New York Mellon Corporation (the "Company") announced the launch of a proposed public offering (the "Offering") of depositary shares, each representing a 1/100^th interest in a share of its new series of Series M Noncumulative Perpetual Preferred Stock (the "Depositary Shares"). The Offering is subject to pricing, which has not yet occurred. If the Offering is priced and proceeds to closing, the Company intends to use the net proceeds from the sale of the Depositary Shares for general corporate purposes, which may include, but is not limited to, the redemption of some or all of its Series F Noncumulative Perpetual Preferred Stock, $100,000 liquidation preference per share (the "Series F Preferred Stock"), on the dividend payment date in September 2026.

The Company also expects, but is not obligated to, redeem some or all of its Series H Noncumulative Perpetual Preferred Stock, $100,000 liquidation preference per share (the "Series H Preferred Stock"), on the dividend payment date in March 2026.

The pricing of the Offering and whether a redemption of the Series H Preferred Stock or the Series F Preferred Stock will occur, is subject to market conditions and other considerations. There is no assurance that the Offering will price and close or that the Company will decide to redeem the Series H Preferred Stock or the Series F Preferred Stock, or, if it does, the amount to be redeemed and the timing of the redemption. This Current Report on Form 8-Kdoes not constitute a notice of redemption with respect to the Series H Preferred Stock or the Series F Preferred Stock. If the Company decides to redeem the Series H Preferred Stock or the Series F Preferred Stock, it intends to announce its decision by press release and an appropriate notice of redemption during the applicable notice window.

The Offering is described in the Company's preliminary prospectus supplement dated February 26, 2026, filed with the Securities and Exchange Commission today.

This Current Report on Form 8-Kdoes not constitute an offer to sell the Depositary Shares.
