***Petrobras confirms new gas discovery in Colombia***

***—***

**Rio de Janeiro, March 18, 2026** – Petróleo Brasileiro S.A. - Petrobras informs a new gas discovery in the Copoazu-1 exploratory well, located in Block GUA-OFF-O in deep waters offshore Colombia.

This discovery consolidates the gas province and the gas potential in the Colombian offshore, while also adds a greater volume of gas to contribute to the region's energy security.

The Copoazu-1 well is located approximately 36 kilometers from the coast, at a water depth of 964 meters and 8 kilometers from the Sirius-1 (discovery) and Sirius-2 (appraisal) wells, highlighting its relevance within the exploratory context of Block GUA-OFF-0.

The drilling of the Copoazu-1 well began on November 11, 2025, and is progressing safely, with respect for the environment and for people.

The gas-bearing intervals were identified through electric logs and fluid sampling, confirming the presence of gas in an additional objective beyond the main objective, making the discovery even more significant. The gas-bearing intervals will be further characterized by laboratory analyses.

Petrobras' activities in Block GUA-OFF-0 are aligned with the company's long-term strategy, aiming to replenish oil and gas reserves through exploration of new frontiers and partnerships with other companies, ensuring the supply of global energy demand during the energy transition.

Petrobras, through its subsidiary Petrobras International Braspetro B.V – Colombia Branch (PIB-COL), acts as the operator of the consortium (44.44% interest), in partnership with Ecopetrol S.A. (55.56% interest).

Material facts will be promptly disclosed to the market.
