USE OF PROCEEDS

We will use the net proceeds from the sale of the Notes for general corporate purposes, including investments in and advances to our bank and nonbank subsidiaries, reduction of outstanding borrowings or indebtedness, short and long-term investments and financing possible future acquisitions including, without limitation, the acquisition of banking and nonbanking companies and financial assets and liabilities. All or a portion of the net proceeds from the sale of Notes may also be used to finance, in whole or in part, our repurchase of common shares pursuant to any share repurchase program securities repurchases undertaken from time to time. The precise amounts and timing of the application of proceeds will vary with liquidity and funding requirements.

CERTAIN UNITED STATES FEDERAL INCOME TAX CONSIDERATIONS

The Company believes that the Notes should be treated as variable rate Notes that are not issued with original issue discount for United States federal income tax purposes. See the discussion in the prospectus supplement under “Certain United States Federal Income Tax Considerations” for a discussion of the United States federal income tax consequences of investing in the Notes.

SUPPLEMENTAL INFORMATION CONCERNING THE PLAN OF DISTRIBUTION

We have entered into a terms agreement, dated December    , 2024 (the “Terms Agreement”), with the agents named below. Subject to the terms and conditions set forth in the Terms Agreement, we have agreed to sell to the agents, and the agents have agreed, severally and not jointly, to purchase, the principal amount of Notes set forth opposite their respective names below:

Agent	Amount of Notes
RBC Capital Markets, LLC	$
BofA Securities, Inc.
M&T Securities, Inc.
Total	$

We expect that delivery of the Notes will be made against payment therefor on or about the closing date specified on the cover page of this pricing supplement, which will be on the    business day following the date the notes are priced (such settlement being referred to as “T+ ”). Under Rule 15c6-1 of the Securities Exchange Act of 1934, as amended, trades in the secondary market generally are required to settle in one business day, unless the parties to any such trade expressly agree otherwise. Accordingly, purchasers who wish to trade the Notes on the Trade Date or the following business day will be required, by virtue of the fact that the Notes initially will not settle in T+1, to specify an alternative settlement cycle at the time of any such trade to prevent a failed settlement and should consult their own advisor.

See “Plan of Distribution (Conflicts of Interest)” in the accompanying prospectus supplement for additional information.
