 their own accounts. Such acquisitions may have an effect on demand for and the price of the Notes.

The expenses of the offering,
excluding the underwriting discount, are estimated to be U.S.$ million and will be borne by PGF. PGF has agreed to reimburse the underwriters
up to approximately U.S.$ for certain of their expenses relating to the offering, including the fees and disbursements of counsel to the
underwriters. Such reimbursement is deemed underwriting compensation by the Financial Industry Regulatory Authority Inc. (FINRA).

Petrobras has been advised by the underwriters that they propose to offer theNotes 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 % of the principal amount of the 20 Notes and a selling concession not in excess of % of the principal amount of the 20 Notes. 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 , 2025, which will be the business day following the date of this prospectus supplement (such settlement being referred to as “T+ ”). 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 theNotes 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 business days (T+ ), 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
