Material Changes and Use of Proceeds

- Providing capital to support growth.
- Repayment, redemption, or repurchase of existing securities.
The filing does not provide comparative financial metrics (revenue, profit, cash flow) as this is a transaction-specific report rather than a periodic earnings filing.
Guidance, Outlook, and Risks
Redemption Terms: The Notes are redeemable by the Bank in whole on November 15, 2030, or in whole or in part on or after August 15, 2035, at 100% of principal plus accrued interest. Early redemption is permitted in the event of a tax, capital, or investment company event.
Risks and Contingencies: The Notes are subordinated obligations, meaning they rank below senior debt and deposit claims. The interest rate is subject to reset risk after 2030, dependent on U.S. Treasury rates.
