Rio de Janeiro, May 9, 2025– Petróleo Brasileiro S.A. – Petrobras informs that it has identified the presence of high-quality oil with no
contaminants in the pre-salt of Santos Basin, in an exploratory well in Aram block.

Well 3-BRSA-1396D-SPS is located

The Aram consortium will begin
laboratory analyses to characterize the conditions of the reservoirs and fluids found, which will allow the evaluation of the area's potential.

The AP has a deadline in 2027,
