Contents

Average utilization rate of petrochemical crackers: increased compared to 2Q21 (+3 p.p.) due to the return of operations after the scheduled general maintenance shutdown at the petrochemical complex in ABC, São Paulo. Compared to 3Q20, decreased (-7 p.p.) mainly due to the feedstock shortage at the petrochemical complex in Rio de Janeiro as a consequence of the process to return after a scheduled shutdown of a national supplier.

Average utilization rate of PP plants^[1]: in the United States, the utilization rate decreased compared to 2Q21 (-4 p.p.) and 3Q20 (-5 p.p.), due to several small fluctuations in the reliability of PP plants in the period.

In Europe, the utilization rate decreased compared to 2Q21 (-4 p.p.), due to small fluctuations in the reliability of PP plants in the period. Compared to 3Q20, the utilization rate increased (+5 p.p.), due to the normalization of operations after the weaker demand in 3Q20, reflecting the impacts of COVID, and fluctuations in the reliability of PP plants in the 3Q20.

Average utilization rate of PE plants: increased 10 p.p. compared to 2Q21, mainly explained by higher ethane imports from the United States under the Fast Track solution, which offset the lower ethane supply from Pemex. Compared to 3Q20, the utilization rate decreased 16 p.p., mainly due to the lower volume of ethane supplied by Pemex.

^[1] Data for the United States in 3Q20 does not consider production capacity and volumes from Delta.

In August, Braskem Idesa completed the project to expand the Fast Track import capacity, which currently stands at 25,000 barrels per day. As a result, during the month of September it reached a historic import volume of 22,400 barrels per day. In 3Q21, in order to complement Pemex's ethane supply, Braskem Idesa imported an average of 18,600 barrels per day of ethane from the United States, which represents approximately 74% of Fast Track's current capacity.

2.   SALES PERFORMANCE 3Q21

Resins sales volume: in the Brazilian market, sales volume increased in relation to 2Q21 (+11%), explained by (i) the higher availability of PE, after the conclusion of the scheduled general maintenance shutdown at the petrochemical complex in ABC, São Paulo; and (ii) the increase in market share in line with the strategy to prioritize serving the local market. Compared to 3Q20, sales volume decreased (-17%), mainly due to: (i) the normalization of resins demand in the local market; and (ii) the lower product availability.

Export volumes increased compared to 2Q21 (+26%), mainly due to the improvement in logistical availability for exports due to the hiring of an additional vessel despite global logistical restrictions in the period. Compared to 3Q20, exports decreased (-10%), due to global logistical restrictions for export, in addition to fewer opportunities in the international market.

Main chemicals sales volume: in the Brazilian market, sales volume increased in relation to 2Q21 (+8%), due to higher product availability. Compared to 3Q20, sales volume increased (+2%), reflecting the increase in gasoline and cumene demand, which was partially offset by lower sales of BTX (benzene, toluene and paraxylene) products due to clients scheduled and unscheduled maintenance shutdown.

Export volumes increased compared to 2Q21 (+18%), driven by the higher export volumes of benzene to capture opportunities in the international market. Compared to 3Q20, exports remained in line.

PP sales volume: in the United States, sales were lower compared to 2Q21 (-2%), due to lower product availability. Compared to 3Q20, the increase of 9% is mainly explained by the ramp-up process of the new PP plant (Delta), with commercial production beginning in September 2020.

In Europe, PP sales volume decreased (-6%) in relation to 2Q21, reflecting the seasonally weaker demand. Compared to 3Q20, the increase (+9%) is explained by the higher product availability in the period and the lower demand in 3Q20, reflecting the impacts of COVID.

PE sales volume: increased 3% compared to 2Q21, due to the higher volume of product available for sale, reflecting the higher utilization rate in the quarter, supported by the increase in ethane imports. In relation to 3Q20, a 29% drop is explained by the lower volume of product available for sale compared to the same period last year.
