Petrobras approves reactivation of fertilizer plant in Araucária (PR)

—

Rio de Janeiro, April 17, 2024 – Petróleo Brasileiro S.A. – Petrobras informs that its Executive Board unanimously approved today the initial measures for the revitalization and future resumption of the Araucária Nitrogenados S/A - ANSA fertilizer plant, a wholly-owned subsidiary of the company. The plant, located in Paraná, has been mothballed since 2020.

ANSA has a production capacity of 720,000 tons/year of urea and 475,000 tons/year of ammonia, as well as 450,000 m³/year of Automotive Liquid Reducing Agent (ARLA 32).

In light of the revision of the company's strategic guidelines approved last year, investment in fertilizer production has once again become part of Petrobras' portfolio. In the first phase of this re-entry into the sector, the strategy has been to reconfigure and consolidate viable operations in assets that already belong to the company.

Regarding ANSA, the executive board approved (i) the negotiation with former employees, and with the Superior Labor Court (TST), of two-year fixed-term employment contracts and salaries compatible with the fertilizer market; (ii) and the start of procedures for contracting maintenance services and critical materials related to the resumption of the industrial plant, located next to the Presidente Getúlio Vargas Refinery (REPAR).

Both the labor agreements and the bidding and contracting process are subject to a new decision by the Board of Executive Officers, once the procedures are well defined.

In addition, Petrobras' Executive Board recommended that ANSA carry out field work to optimize the scope of the scheduled stoppage and assess the integrity of the equipment.

As of next week, Petrobras' technical and administrative areas will continue to work on internal analyses, consultations and recommendations with a view to providing all the conditions for the next deliberations regarding the resumption of ANSA's operations.

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