Petrobras approves reactivation of fertilizer plant in Araucária (PR)

—

Rio de Janeiro, June 6, 2024 – Petróleo Brasileiro S.A – Petrobras, following up on the release disclosed on April 17, 2024, informs that its Executive Board approved today the resumption of operating activities of fertilizer plant Araucária Nitrogenados S.A. (ANSA), a wholly-owned subsidiary of the company. The plant, located in the state of Paraná, has been mothballed since 2020.

All procedures required for the reopening of the plant will be initiated right away, including the release of notices for the contracting of maintenance services and critical materials. With the decision, Petrobras also authorizes ANSA to enter into an agreement to hire its former employees, conditional on the agreement being ratified by the Superior Labor Court (TST). The operation is expected to restart in the second half of 2025.

In light of the review of the company’s strategic guidelines approved last year, investing in fertilizer production has once again become part of Petrobras’s portfolio, according to the 2024 - 2028+ Strategic Plan.

Located next to the Presidente Getúlio Vargas Refinery - REPAR, ANSA has a production capacity of 720,000 tons/year for urea, 475,000 tons/year for ammonia, and 450,000 m³/year of Automotive Liquid Reducing Agent (ARLA 32).

Material facts on the subject will be disclosed to the market in due course.
