 the Notes of each series initially at the applicable public
offering price set forth on the cover page of this prospectus supplement and to dealers at that price less a selling concession not in
excess of 0.180% of the principal amount of each series of the Notes. The underwriters may allow, and those selected dealers may re-allow,
a concession not in excess of 0.120% of the principal amount of each series of the Notes to certain other dealers. After the initial public
offering of each series of the Notes, the public offering price and concession and discount to dealers may be changed.

We expect to deliver the Notes against payment for the Notes on or about September 10, 2025, which will be the fifth business day following the date of this prospectus supplement (such settlement being referred to as “T+5”). Under Rule 15c6-1 of the Exchange Act, trades in the secondary market
generally are required to settle in one business day, unless the parties to such trade expressly agree otherwise. Accordingly, purchasers
who wish to trade the Notes prior to the date that is one business day prior to the delivery of the Notes will be required, by virtue
of the fact that the Notes initially will settle in five business days (T+5), to specify alternative settlement arrangements to prevent
a failed settlement.

The Notes are offered for
sale in the United States and other jurisdictions where it is legal to make these offers. The distribution of this prospectus supplement
and the accompanying prospectus, and the offering of the Notes in certain jurisdictions may be restricted by law. Persons into whose possession
this prospectus supplement and the accompanying prospectus come and investors in the Notes should inform themselves about and observe
any of these restrictions. This prospectus supplement and the accompanying prospectus do not constitute, and may not be used in connection
with, an offer or solicitation by anyone in any jurisdiction in which such offer or solicitation is not authorized, or in which the person
making such offer or solicitation is not qualified to do so, or to any person to whom it is unlawful to make such offer or solicitation.

The underwriters have agreed
that they have not offered, sold or delivered, and they will not offer, sell or deliver any of the Notes, directly or indirectly, or distribute
this prospectus supplement, the accompanying prospectus or any other offering material relating to the Notes, in or from
