Contents

Average utilization rate of petrochemical crackers: reduction in relation to 4Q20 (-3 p.p.), mainly due to the pit stop (rapid scheduled maintenance shutdown) carried out at the petrochemical cracker in Rio Grande do Sul. Compared to 1Q20, the capacity utilization rate of the crackers in Brazil increased (+2 p.p.), reflecting the non-scheduled shutdown of the cracker in Rio Grande do Sul in the prior year quarter.

Average utilization rate of PP plants: in the United States, considering the production and capacity of the new PP plant (Delta) in 1Q21, the utilization rate decreased in relation to 4Q20 (-6 p.p.) and 1Q20 (-18 p.p.), reflecting the impacts from winter storm Uri in the U.S. Gulf Coast. In Europe, utilization rate increased in relation to 4Q20 (+30 p.p.), explained by the scheduled maintenance shutdown which occurred in the last quarter of the prior year. Compared to 1Q20, the utilization rate increased (+5 p.p.) due to the inventory rebuilding effect and the normalization of demand that was impacted in 1Q20 by COVID.

Average utilization rate of PE plants: increased from 4Q20 (+10 p.p.), due to the production based on an experimental business model implemented in January and February, following the unilateral

interruption of natural gas transport service by Cenagas in early December 2020. In early March, after executing a natural gas transportation service agreement with Cenagas, transportation services were reestablished. Compared to 1Q20, the rate decreased (-28 p.p.), given the need to operate the industrial assets during most of 1Q21 under the experimental model, besides the lower ethane availability due to the impacts from winter storm Uri in the U.S. Gulf Coast.

Resin sales volume: in the Brazilian market, decreased compared to 4Q20 (-5%), due to the weaker demand in the Brazilian market and the lower product availability in the period. Compared to 1Q20, sales increased (+8%), due to the stronger demand in the local market. The reductions in exports compared to 4Q20 (-15%) and 1Q20 (-41%) are explained by the Brazil segment’s strategy to prioritize sales to the local market.

Main chemicals sales volume: in the Brazilian market, sales contracted compared to 4Q20 (-3%), explained by the lower product availability, given the lower utilization rate of the petrochemical crackers. In relation to 1Q20, sales in the Brazilian market increased (+17%), led by sales of gasoline (+20%), given the pandemic’s impacts on fuel demand in 1Q20, and of benzene (+21%), explained by the rowing market for polystyrene. Meanwhile, exports decreased in relation to 4Q20 (-3%), given the strategy to prioritize sales to the Brazilian market, and remained stable in relation to 1Q20.

PP sales volume: in the United States, considering the sales of the new PP plant (Delta), sales volume increased compared to 4Q20 (+17%) and to 1Q20 (+7%) mainly due to the increase in production

capacity after the commercial startup of the new PP plant (Delta) in the region in September 2020. Also, the increase compared to 4Q20 is explained by the sales of products in inventories to meet market demand and reduce effects from the lower production in the short term due to winter storm Uri. In Europe, sales increased in relation to 4Q20 (+25%) and 1Q20 (+13%), due to the higher product availability in the period.

PE sales volume: decreased in relation to 4Q20 (-27%) due to the lower supply of product in inventory, which was partially consumed in 4Q20 after the operational shutdown in Mexico in December 2020. Compared to 1Q20, sales decreased (-37%) due to the lower supply of product for sale.
