| Underwriters               |     | Number of Corporate Units |     |            |
| BofA Securities, Inc.      |     |                           |     |            |
| J.P. Morgan Securities LLC |     |                           |     |            |
| Mizuho Securities USA LLC  |     |                           |     |            |

The offering of the Corporate Units by the underwriters is subject to receipt and acceptance of the Corporate Units and subject to the underwriters’ right to reject any order in whole or in part.

After the initial public offering of the Corporate Units, the offering price and other selling terms may be changed.

The Corporate Units are a new issue of securities with no established trading market. The Company intends to apply to list the Corporate Units on the New York Stock Exchange. If the application is approved, the Company expects trading in the Corporate Units to begin within 30 days after the date that the Corporate Units are first issued.

The underwriters may make a market in the Corporate Units after completion of the offering, but will not be obligated to do so and may discontinue any market-making activities at any time without notice. No assurance can be given as to the liquidity of the trading market for the Corporate Units or that an active public market for
