In 1Q25, the average production of oil, LGN, and natural gas reached 2.77 MMboed, 5.4% above 4Q24, mainly due to the lower volume of losses from maintenance shutdowns; improved operational efficiency in the Santos Basin; the production start-up of FPSO Almirante Tamandaré in the Búzios field; and the ramp-up of FPSO Marechal Duque de Caxias in the Mero field, factors partially offset by the natural decline in production. In this quarter, 11 new producing wells started operations, 6 in Campos Basin and 5 in Santos Basin.

Highlight the main events in 1Q25:

• FPSO Almirante Tamandaré (photo) started production on February 15 in the Búzios field, in Santos Basin pre-salt. The unit has the capacity to produce up to 225,000 barrels of oil per day and to process up to 12 million cubic meters of gas. This is the first of six systems contracted by Petrobras to operate with this oil production capacity, and the next five units will be owned by us. The unit is expected to reach production capacity by the end of this year.
• Additionally, FPSO Almirante Tamandaré began gas injection on April 5, just 49 days after start-up. This is another record for Santos Basin pre-salt, with the previous record of 52 days achieved by FPSO Almirante Barroso, also located in the Búzios field. Gas injection is one of the factors which contribute to production growth.
• The start-up of the 2nd producing well of FPSO Marechal Duque de Caxias took place on February 12 in the Mero field, reaching an operated daily production of about 95,000 barrels of oil. We expect to reach peal production in the second quarter.
• After leaving China in December 2024, FPSO Alexandre de Gusmão arrived at the Mero field, in the Libra block in Santos Basin, on March 3. Anchoring was completed in just 10 days. The unit is expected to start operating between the 2nd and 3rd quarter of 2025. The platform has the capacity to produce 180,000 barrels of oil per day, in addition to processsing 12 million cubic meters of gas.

Achieved several production records this quarter, among which the following stand out:

• Operating oil + NGL production in the pre-salt in 1Q25: 2.77 MMboed (previous record of 2.76 MMboed in 4Q23).
• Total operated production in the pre-salt in 1Q25: 3.39 MMboed (previous record of 3.34 MMboed in 4Q23).

In 1Q25, sales of oil products in the domestic market increased 2.9% when compared to 1Q24, driven by diesel, gasoline, and jet fuel.We recorded a 73% share of pre-salt oil in refinery throughput in this quarter, 2 percentage points above 4Q24 and matching the record set in 3Q24. The high share of pre-salt oils in throughput reinforces the focus on optimizing the use of these streams for the production of higher value-added oil products and the reduction of atmospheric emissions. We achieved a high yield in the production of middle distillates (diesel and jet fuel) and gasoline, which accounted for 69% of the total volume of oil products in 1Q25, despite RNEST's significant planned shutdown this quarter, during which the modernization of Train 1 was completed.

In February 2025, Petrobras made its first sale of VLSFO (Very Low Sulfur Fuel Oil) with 24% renewable content in the Asian market, in partnership with Golden Island, a bunker supplier in Singapore. The product is a blend of 76% mineral fuel oil and 24% UCOME, a biofuel made from waste cooking oil. Petrobras Singapore holds ISCC EU certification (International Sustainability & Carbon Certification - European Union), ensuring the sustainability of the product.
