| Parties | Braskem S.A (“Braskem” or the “Company”) e Petrocoque S.A. Indústria e Comércio (“Petrocoque”) |
| Relationship with the Issuer | Petrocoque is a company under the joint control of Petróleo Brasileiro S.A. – Petrobras (which holds 50% of its share capital), a shareholder with significant influence over Braskem. |
| Purpose | Agreement for the purchase of steam for Braskem’s PE8 plant, located in Cubatão/SP, to be supplied by Petrocoque, also located in Cubatão/SP. |
| Key Terms and Conditions |
Braskem S.A. (“Braskem” or the “Company”) will purchase steam (energy supplied in the form of steam to Braskem’s PE8 unit in Cubatão) generated by PETROCOQUE, since that it meets the specifications defined in the agreement, with no penalties involved.
(i) Term: from March 25, 2026, to March 24, 2031, and may be extended by mutual agreement between the parties until March 24, 2033.
(ii) Total amount: estimated at BRL 226 million. |

| Possible participation of the counterparty, its shareholders or officers in the issuer’s decision-making process or in the negotiation of the transaction as representatives of the issuer | There was no participation by the counterparty, its shareholders, or its officers in Braskem’s decision-making process or in the negotiation of the agreement. |
| Detailed justification of the reasons why the issuer's management considers that the transaction has complied with commutative conditions or provides for an appropriate reverse payment | Considering that Petrocoque is the only supplier for the PE8 unit located in the Cubatão region, a competitiveness analysis was conducted by comparing the commercial conditions agreed upon under this agreement with those of other steam supply agreements entered into by Braskem with different suppliers at its other units. Based on this analysis, it was concluded that the price established under the agreement is competitive and consistent with market conditions. |
