12.3% reduction compared to 1Q25 (US$ 6.79/boe). This reduction occurred
in Pre-Salt and Post-Salt layer fields and was was driven by lower expenses
due to reduced well intervention activities, as well as decreased expenses for subsea inspections, in addition to reduced logistical support
costs. Increased production also contributed to the reduction in the lifting cost. Nevertheless, these effects were partially offset by
the 3% appreciation of the Brazilian real against the US dollar.

In Pre-salt, there was a 13.9%
reduction in lifting cost, explained by lower expenses with well interventions in the Búzios field, decreased expenses for subsea
inspections in the Atapu, Sapinhoá, and Sépia fields, as well as reduced logistical support costs. The increase in production
also contributed, mainly due to the ramp-up of the FPSOs Almirante Tamandaré (Búzios) and Marechal Duque de Caxias (Mero),
as well as the start-up of the FPSO Alexandre de Gusmão and new wells in Santos Basin. These effects were partially offset by the
3% appreciation of the Brazilian real against the US dollar.

In Post-salt, there was a 6.5%
reduction in lifting cost, explained by lower expenses with well interventions and subsea inspections in the Roncador and Barracuda fields,
as well as decreased logistical support costs. However, there were higher volumes of losses with maintenance shutdowns and the natural
decline of the fields, alongside the 3% appreciation of the Brazilian real against the US dollar.

In Onshore and Shallow Waters,
there was a 3% increase in lifting cost. This increase resulted from the gradual production resumption at Manati in 2Q25, which has higher
operating unit costs, alongside the impact of the 3% appreciation of the Brazilian real against the US dollar.
