| 1. | OPERATIONAL OVERVIEW 2Q26 |

In the second quarter of 2026,
the global macroeconomic environment remained volatile due to the conflict in the Middle East, which constrained the global supply of
feedstocks and increased oil prices and, consequently, naphtha prices in the international market. In this context, resin and chemical
prices in international markets were higher compared to the first quarter of 2026, positively impacting the operating results of the Company's
reportable segments.
In the Brazil/South America segment,
the average utilization rate of petrochemical crackers remained in line with 1Q26, mainly explained by the high volatility of feedstock
prices in international markets. The sales volume of resins was lower compared to the previous quarter due to the prioritization of higher
value-added sales, impacting the segment’s inventory levels.
In the United States and Europe
segment, the average utilization rate of PP plants was lower compared to 1Q26, mainly explained by scheduled maintenance shutdowns in
the United States and Europe. The sales volume of PP was higher, in line with increased demand in the United States, partially offset
by lower sales volume in Europe, mainly explained by inventory management across the transformation chain.
In the Mexico segment, the average
utilization rate of the PE plants was lower compared to 1Q26, mainly due to the liquidity preservation measures adopted by Braskem Idesa.
Average utilization rate of
petrochemical crackers: remained in line (+1 p.p.) compared to 1Q26, mainly due to the Company’s strategy to maintain production
levels amid volatility in international price references and uncertainties regarding the duration of the conflict in the Middle East.
In relation to 2Q25, the average
utilization rate of petrochemical crackers was lower (-4 p.p.), mainly due to lower production at (i) Rio de Janeiro petrochemical complex,
explained by lower feedstock availability; and (ii) Rio Grande do Sul petrochemical complex, explained by the adjustment of production
levels in response to lower demand between the periods.

Resin’s sales volume:
in the Brazilian market, the sales volume was lower (-2%) compared to 1Q26, due to lower sales volumes of PE (-6%) and PVC (-1%), mainly
explained by higher import volumes during the period. This effect was partially offset by higher PP sales volume (+3%), which followed
increased demand in the Brazilian market.
In relation to 2Q25, the reduction
(-8%) is mainly due to (i) lower PE (-9%) and PP (-5%) sales volumes, as a result of higher import volumes during the period; and (ii)
lower PVC sales volumes (-2%) due to inventory management across the transformation chain, as previously mentioned.

Resin export volume was lower
(-4%) compared to 1Q26, mainly due to lower export volumes of PP (-11%) and PE (-5%), primarily explained by the prioritization of supply
to the Brazilian market and lower product availability for export. This effect was partially offset by higher PVC export volume due to
specific commercial opportunities.
In relation to 2Q25, the reduction
(-23%) is mainly explained by lower PE export volumes (-33%), as previously mentioned.

Main chemicals sales volume1:
in the Brazilian market, the main chemicals sales volume was lower (-4%) compared to 1Q26, mainly due to lower sales volumes of (i) gasoline
and benzene, explained by lower product availability for sale; and (ii) ethylene and cumene, explained by lower demand in the Brazilian
market.
Compared to 2Q25, main chemicals
sales volume in the Brazilian market was lower (-5%), mainly due to lower sales volumes of: (i) gasoline, explained by lower product availability
for sale, as previously mentioned; (ii) benzene, explained by the shutdown of a customer’s plant; and (iii) cumene, explained by
lower demand in the Brazilian market due to operational adjustments by customers.

1 Main chemicals refer to: ethylene, propylene, butadiene, cumene, gasoline, benzene, toluene and paraxylene based on their relevance to
the segment’s net revenue.
The increase in exports compared to
1Q26 (+55%) and 2Q25 (+55%) is mainly explained by higher cumene and benzene export volumes, driven by greater product availability for
sale as a result of lower demand in the Brazilian market.

Average utilization
rate of green ethylene:

higher (+2 p.p.) compared to 1Q26, mainly explained by the adjustment of production levels to meet higher seasonal
demand following the Chinese New Year in 1Q26.
In relation to 2Q25, the reduction (-5
p.p.) is mainly explained by inventory optimization throughout the quarter to align with global demand levels.

Green PE (I’m
greenTM biobased) sales volume: higher (+49%) compared to 1Q26, mainly explained by (i)
better commercial opportunities in Europe; and (ii) the seasonal effect following the Chinese New Year in 1Q26, as previously mentioned.
In relation to 2Q25, the green PE sales
volume reduction (-19%) is mainly explained by inventory management across the transformation chain due to uncertainties related to macroeconomic
volatility.

| 2.2 | UNITED STATES & EUROPE |
Average utilization
rate of PP plants: lower (-3 p.p.) compared to 1Q26, mainly explained by (i) a 35-day scheduled maintenance
shutdown at a plant in the United States; and (ii) a 32-day scheduled maintenance shutdown at the Wesseling plant in Germany, which began
in April.
Compared to 2Q25, the average utilization
rate was higher (+2 p.p.), mainly explained by the normalization of operations following a maintenance pit stop at a plant in the United
States in 2Q25, partially offset by the maintenance shutdown in Europe, as previously explained.

PP sales volume:
remained in line (+0%) compared to 1Q26, with higher sales volume in the United States, in line with increased
demand in the region, offset by lower sales volume in Europe due to inventory management across the region’s transformation chain.
Compared to 2Q25, PP sales volume was
lower (-1%), mainly due to lower sales volume in Europe, explained primarily by lower demand in the region. This effect was partially
offset by higher sales volume in the United States, mainly explained by higher export volumes and increased demand in the U.S. market,
as previously mentioned.

Average utilization rate of PE
plants: lower compared to 1Q26 (-12 p.p.), mainly due to the liquidity preservation measures being implemented by Braskem Idesa. Average
ethane imports through the terminal totaled 14.7 thousand barrels per day in 2Q26, lower than the 17.8 thousand barrels per day recorded
in 1Q26. Average ethane supply by PEMEX totaled 11.8 thousand barrels per day in the quarter, lower than the average volume of 14.8 thousand
barrels per day in 1Q26.
In relation to 2Q25, the average utilization
rate of PE plants was in line (-1 p.p.).

PE sales volume: lower compared
to 1Q26 (-11%) and 2Q25 (-20%), mainly due to lower product availability for sale, explained by the lower average utilization rate of
PE plants, as previously mentioned.

PETROCHEMICAL SPREADS
The global environment remains subject
to geopolitical tensions in strategic regions, particularly in the Middle East, which have led to volatility in oil and petrochemical
feedstock prices, impacting international prices of resins and chemicals sold by industry and the Company, as well as creating uncertainties
regarding potential logistics constraints. The Company continues to closely monitor the potential impacts associated with these dynamic
events, assessing their effects on the conduct of its operations.
