Economic Scenario The effects of the war in the Middle East have generated a scenario of volatility in international prices, redirections of trade flows, and exchange rate volatility. As a result, there are inflationary pressures in several of the world's largest economies, leading the world's major central banks to maintain interest rates at historically high levels. This context puts pressure on the global economic growth rate, which is partially offset by the growth of massive investments in technology globally, some of which are directed towards the application of artificial intelligence and its support structures. The IMF (International Monetary Fund) report for July 2026 projects that the global economy will grow by 3.0% in 2026 and 3.4% in 2027, a slightly lower rate than that observed in 2024-2025. Regarding global inflation, the projection is 4.7% in 2026 and 3.9% in 2027. Brent crude oil averaged $97/bbl in 2Q26, with strong volatility reflecting geopolitical tensions and concerns about global supply. Critical inputs for Unipar's operations, such as ethylene and natural gas, generally followed Brent price movements throughout 2Q26. Brazil According to IBGE data, Brazil accumulated an inflation rate (IPCA) of 3.4% in the first half of 2026. According to the Focus Report of July 31, 2026, the projected IPCA for 2026 is 5.0%, that is, above the center of the target established by the Central Bank. In terms of GDP growth for the Brazilian economy, the same report indicates 2.0% for 2026 and 1.6% for 2027, in addition to projecting a Selic rate of 13.75% p.a. for the end of 2026. The Focus Report projections indicate a still contractionary monetary policy ahead, consistent with a series of macroeconomic challenges observed in Brazil, especially the fiscal deficit and the recurring increase in the ratio between net public debt and the country's GDP. The average BRL/USD exchange rate in 2Q26 was R$5.05, 4% lower than in 1Q26. For the end of 2026, the Focus Report of July 31, 2026, projects an exchange rate of R$5.20. Argentina Argentina's scenario has shown positive progress in its macroeconomic and fiscal recovery, with recurring fiscal surpluses and a projected GDP growth of 3.5% for 2026 and 4.0% for 2027, according to an IMF report from July 2026. Inflation in the country in the first half of 2026, according to the Consumer Price Index (CPI) released by INDEC – the National Institute of Statistics and Censuses – accumulated 16.8%, registering an accumulated rate of 33.5% over the last twelve months. Regarding the official average exchange rate of the Central Bank, the average rate was $1,406 Argentine pesos/dollar in the second quarter of 2026, 1% below the average of the first quarter of 2026.

Earnings Release 2Q26 4 Operating Market International caustic soda and PVC price benchmarks had significant increases during 2Q26 due to the conflicts in the Middle East during that period. The average price of liquid soda (US Gulf Coast, spot, export) in 2Q26 increased by 26% compared to 1Q26, returning to the average price level observed in 2Q25. For PVC, the average international price (US Gulf Coast, spot, export) in 2Q26 was 53% higher than the price in 1Q26, and 38% higher than the price in 2Q25. The chart below shows international prices based on 100 in December/2024, corresponding to the indicative quarterly price (month – 1). International Price Evolution Base 100: December 2024 = 100 (Source: Consulting firm) Price PVC US Export FOB Price Soda US Export Operating Performance Utilization Rate of the Installed Capacity - Electrolysis Average electrolysis utilization in 2Q26 was 84% in Brazil, 12 p.p. higher than the previous quarter, due to the successful start of operations of the new technology installed at the Cubatão plant in March 2026, with positive effects on production efficiency and reliability. In Argentina, utilization in 2Q26 was 73%, in line with the previous quarter, reflecting, among other factors, a stable level of operation and integration with Brazil in sales management and inventory reduction. Brazil Argentina Consolidated Financial Performance Unipar’s consolidated financial results are impacted by the effects of inflation in Argentina and the variation of the exchange rate of Argentine peso, according to the application of the accounting standard IAS 29 (hyperinflation accounting) and process of converting the financial statement of Unipar Indupa SAIC (Bahía Blanca plant) into Brazilian reais using the exchange rate at the end of the period. The following comparisons are managerial (“adjusted”) and exclude these effects. Net Operating Revenue Adjusted Consolidated Net Operating Revenue totaled R$1,494 million in 2Q26, 14% higher than in 2Q25, mainly due to (i) higher sales volumes in all segments: +9% in caustic soda, +6% in PVC, and +4% in chlorin e vs. 1Q26 and (ii) international caustic soda price in line and +38% in the international PVC benchmark, partially offset by the adverse impact of the appreciation of the BRL vs USD. Compared to 1Q26, revenue increased 22%, mainly driven by (i) higher caustic soda and chlorine sales volumes with monthly records: +7% and +19% respectively vs 1Q26 and (ii) increases of +26% and +53% in international references for caustic soda and PVC, partially affected by the 11% lower PVC sales volume due to the selectivity applied by Unipar to PVC sales in Brazil, given the pressure from imports, and the adverse 102 99 95 86 89 136 99 111 97 93 88 111 1Q25 2Q25 3Q25 4Q25 1Q26 2Q26 66% 74% 67% 73% 73% 73% 86% 82% 80% 81% 72% 84% 1Q25 2Q25 3Q25 4Q25 1Q26 2Q26 82% 80% 77% 79% 73% 81%

Earnings Release 2Q26 5 effect of the +4% appreciation of the BRL vs USD. In 1H26, adjusted net revenue was virtually flat, increasing 1%, reflecting (i) higher international PVC prices, partially offset by lower caustic soda prices and (ii) higher sales volumes of caustic soda and PVC, and (iii) the appreciation of the BRL vs USD. Adjusted Consolidated Net Operating Revenue (R$ million) Brazil Argentina Adjusted Consolidated Net Operating Revenue By Product 2Q25 1Q26 2Q26 R$ 1,313 million R$ 1,221 million R$ 1,494 million Chlorine PVC Caustic Soda COGS (Cost of Goods Sold) Adjusted consolidated COGS totaled R$974 million in 2Q26, 8% higher than in 2Q25, mainly due to (i) higher sales volume in all product segments (caustic soda, chlorin e and PVC) and (ii) a 29% increase in the international price of ethylene based on Europe and a significant increase in the cost of natural gas, partially offset by the appreciation of the BRL vs Euro and by better technical coefficients in Cubatão as a result of the successful start of operations with the new technology. Compared to 1Q26, the increase was 4% resulting from (i) higher sales volume of caustic soda and chlorin e, (ii) +34% in the average international price of ethylene based on Europe and (iii) + ~30% in the price of natural gas, partially offset by a 5% appreciation of the BRL vs Euro, lower sales volume of PVC and better technical coefficients in Cubatão after technological substitution. In 1H26, COGS totaled R$1,908 million, 6% higher than in 1H25, mainly reflecting (i) higher sales and resale volumes and (ii) higher raw material costs, particularly ethylene and natural gas. 22% 38% 40% 23% 40% 37% 23% 41% 36% 1,043 960 1,200 270 261 294 2Q25 1Q26 2Q26 1,4941,313 +22% 1,221 +14% 2,108 2,160 568 555 1H25 1H26 2,7152,676 +1%

Earnings Release 2Q26 6 Adjusted COGS Consolidated Selling Expenses Adjusted Selling Expenses totaled R$ 69 million in 2 Q26, 6% higher in 1Q26 and 15% higher than in 2Q25. In 1H26, adjusted selling expenses totaled R$ 134 million, 8% higher than in 1H25, due to higher caustic soda sales volumes compared to previous periods. In 2Q26, unlike 1Q26 and 2Q25, there was opportunistic sales of caustic soda from third parties (resale), which affects the comparison of sales expenses between the quarters. General and Administrative Expenses Adjusted General and Administrative Expenses totaled R$ 106 million in 2Q26, 3% higher than in 1Q26 and 9% higher than in 2Q25, mainly due to payroll adjustments involving expenses for replacing administrative staff. In 1H26, adjusted general and administrative expenses totaled R$ 209 million, 12% higher than 1H25. Equity Pick-Up Consolidated Equity Pick-Up, referring to the equity pick -up in the energy companies Solalban, Tucano Holdings III, Lar do Sol and Veleiros was negative by R$ 6 million in 2Q26 and negative by R$14 million in 1H26. The three renewable energy projects have suffered the recurring effects of the energy curtailment established by the ONS (National System Operator). EBITDA (calculated according to CVM Resolution 156/22) Recurring Adjusted EBITDA in 2Q26, excluding IAS 29 effects, totaled R$402 million, 31% higher than Recurring Adjusted EBITDA in 2Q25 impacted by the following factors: ✓ 38% increase in the international prices of PVC, and maintenance of caustic soda prices; ✓ Increase in caustic soda, PVC and chlorine sales volume (+9%, +6% and +4%, respectively); ✓ Adverse effect from 11% appreciation of BRL vs USD; ✓ Capture of recurring reductions in fixed costs, especially through automation initiatives, team redesign and process reviews; ✓ Exclusion of the non-recurring negative effect of negative margin provision on PVC inventory in 2Q26. 74% 77% 70% 21% 19% 24% 5% 4% 6% 2Q25 1Q26 2Q26 73% 73% 22% 22% 5% 5% 1H25 1H26 904 935 +4% Var.

Earnings Release 2Q26 7 Compared to 1Q26, Recurring Adjusted EBITDA was 177% higher impacted by the following factors: ✓ Increase in international prices of caustic soda and PVC (+26% and +53%, respectively); ✓ Higher sales volume of caustic soda and chlorine (+7% and +19%, respectively), with an 11% reduction in PVC sales volumes; ✓ Adverse effect of the 4% appreciation of the BRL vs USD; ✓ Exclusion of the non-recurring negative effect of the negative margin provision on PVC inventory in 2Q26. Recurring Adjusted EBITDA in 1H26, totaled R$547 million, 17% lower than Recurring Adjusted EBITDA in 1H25 impacted by the following factors: ✓ Reduction in the average international prices of caustic soda (-5%), offset by increase in PVC prices (+13%); ✓ 10% appreciation of the BRL vs USD; ✓ Exclusion of the positive effect from the gain of the arbitration process in 2Q25 and the non-recurring positive effect from the reversal of the negative margin provision on PVC inventory in 1H26. The effects of the application of IAS 29 on Unipar Indupa SAIC’s financial information, with no cash effect, are presented in the table below. The effect of the application of IAS 29 - Accounting and Disclosure in Highly Inflationary Economies results from the combination of inflation indexing in the income accounts, with a corresponding entry in the financial result, and the difference between translating the results into Reais using the closing exchange rate of the reported period, and the conversion by the accumulated average rate in the period.

Earnings Release 2Q26 8 Net Financial Result Consolidated Net Financial Result was negative by R$ 87 million in 2Q26, 172% higher than in 1Q26, mainly due to the higher gross debt balance in 2Q26 and the effects of exchange rate movements on loans between related parties, partly denominated in USD and partly in ARS. The financial revenue of 2Q25 had the non-recurring effect of R$ 39 million related to the monetary update of an arbitration process won by Unipar in that period. In the 1H26, the net financial result was negative by R$ 119 million, 284% higher than in the 1H25, mainly due to the effect of the increase in the net debt balance from 1H25 to 1H26 affected by the technological substitution project in Cubatão, which was finished in the 2Q26, and the non -recurring revenue in 1H25 related to the gain in the arbitration process mentioned above.

Earnings Release 2Q26 10 completed strategic Capex (new Camaçari plant completed at the end of 2024 and Cubatão technological replacement project completed in March 2026). The Company's operating cash flow reached R$ 663 million in 1H26, having been positively impacted by the increase in sales of caustic soda and PVC in 1H26, which resulted in a significant reduction in the PVC inventory balance between the end of 2025 and t he end of 1H26. In 1H26, there was also an inflow of funds from BNDES, totaling 88% of the total amount financed for the technology change at the Cubatão plant. Among the cash outflows, the Capex of R$ 319 million and interest payments on debenture issuances stand out. Beginning in 2Q26, the effects of the accelerated tax depreciation of the CAPEX invested in Cubatão became apparent, which is expected to significantly reduce income tax and social contribution expenses over the next 30 months.
