Average utilization rate of petrochemical crackers: in line with 4Q21 (+1 p.p.). Compared to 1Q21, the utilization rate of the petrochemical crackers increased (+4 p.p.), due to the pit stop (rapid scheduled maintenance shutdown) at the petrochemical crackers in Rio Grande do Sul in 1Q21.

Average utilization rate of green ethylene: remained stable compared to 1Q21 (-1 p.p.) and decreased in relation to 4Q21 (-18 p.p.), due to the scheduled maintenance shutdown in 1Q22.

Average utilization rate of PP plants: in the United States, the rate increased in relation to 4Q21 (+15 p.p.) due to the normalization process of operations after a scheduled maintenance shutdown at one of the region's plants in 4Q21. Compared to 1Q21, the rate increased (+10 p.p.), mainly due to the impacts from Winter Storm Uri on the U.S. Gulf Coast in 1Q21.

In Europe, the utilization rate increased compared to 4Q21 (+5 p.p.), due to the normalization of production after the restarting of operations of a local supplier after a scheduled maintenance shutdown in the previous quarter. Compared to 1Q21, the rate decreased (-4 p.p.), due to lower demand in the period.

Average utilization rate of PE plants: stable in relation to 4Q21 (-1 p.p.). In 1Q22, ethane supply by PEMEX was 33,500 barrels per day, higher than the volume established in the amendment to the ethane supply agreement (30,000 barrels per day). Additionally, the Fast Track solution complemented the supply of feedstock with 16,200 barrels per day of ethane imported from the United States, representing 65% of the Fast Track utilization rate, due to the weather problems that occurred in February 2022.

Compared to 1Q21, the increase (+22 p.p.) is mainly explained by the operation of Braskem Idesa's industrial assets based on an experimental business model in January and February 2021, following the interruption in natural gas transport service in early December 2020.

Resin sales volume: in the Brazilian market, increased compared to 4Q21 (+2%), positively impacted from stronger demand for PE and PP for the restocking in the chain. Compared to 1Q21, sales volume decreased (-7%), mainly due to weaker resins demand in the Brazilian market, due to the restocking effect in the chain in 1Q21 after the impacts of COVID.

Green PE sales volume: green PE sales decreased in relation to 4Q21 (-10%) and 1Q21 (-8%), due to logistic constraints in exports.

Main chemicals sales volume^[1]: in the Brazilian market, sales volume increased in relation to 4Q21 (+2%), supported by the higher sales volume of paraxilene, due to the higher production in the period as a consequence of the scheduled maintenance shutdown in 4Q21. Compared to 1Q21, sales volume increased (+3%), due to the higher sales volume of gasoline, due to the social isolation measures in 1Q21.

Exports decreased compared to 4Q21 (-47%), mainly due to the lower ethylene and benzene exported volumes, and in the case of benzene, priority was given to serving the Brazilian market and healthy demand . Compared to 1Q21, exports decreased (-24%), due to the lower ethylene sales.

PP sales volume: in the United States, sales volume increased in relation to 4Q21 (+9%) and 1Q21 (+3%), due to higher product availability.

In Europe, PP sales volume increased (+9%) in relation to 4Q21, reflecting the higher product availabilityfor sale in the period. Compared to 1Q21, the decrease (-6%) is explained by lower product availability and lower demand.

PE sales volume: increased (+15%) compared to 4Q21, due to higher product availability for sale because of the maintenance of production at healthy levels and consumption of the Company's inventory. In relation to 1Q21, the increase (+63%) is explained by the higher product availability for sale compared to the prior-year period.
