Source:ExternalconsultanciesandBraskemMarketIntelligence\|Note(1):ExternalconsultanciesandBraskemanalyses;(2):CTO=Coal-to-Olefins;(3):MTO=Methanol-to-Olefins. IMPACTS ON THE GLOBAL PETROCHEMICAL INDUSTRY • Higher oil prices increase costs for naphtha-based petrochemicals and, consequently, global prices. • Reduced benefits from discounted oil prices for Asian countries such as China and India. • Uncertainties regarding the security of feedstock supply for Asian and Middle East capacities are likely to persist. ECONOMIC AND LOGISTICS IMPACTS ARE EXPECTED TO PERSIST • Direct damage to assets and prolonged logistics disruptions increase the duration of feedstock and finished-product supply delays. • Some temporary shutdowns may be prolonged or become permanent. • A downside risk to discretionary demand may materialize. The impacts presented are hypotheses and may or may not materialize, depending on the evolution of the geopolitical conflict andpotential restrictions in the Strait of Hormuz. 50 60 70 80 90 100 110 120 130 140 150 0 200 400 600 800 1.000 1.200 25/3 27/3 31/3 2/4 8/4 10/4 14/4 23/2 20/4 22/4 24/4 28/4 30/4 25/2 27/2 3/3 5/3 9/3 11/3 13/3 17/3 19/3 23/3 16/4 +56% Brent Naphtha ARA Beginning of the conflict between the U.S.-Israel and Iran Braskem's geographic and product portfolio diversity make it possible to capture value in the short term, amid the scenario of global capacity constraints and rising logistics costs Oil (Brent) and Naphtha (ARA) (US$/bbl) 16 \| PUBLIC PCUOBNLFIICDENTIAL Source:Externalconsultancies.\|Notes:(1)MainChemicalsprice–Naphtha;(2)averagefor2010to2025;(3)PEU.S.(54%)+PPAsia(33%)+PVCAsia(13%);(4)U.S.&EuropePPspread=[AveragePP=PPU.S.(72%)+PPEurope(28%)]–[PGPPropyleneU.S.(72%)+PGPPropyleneEurope(28%)];(5)PEMexicospread=[PEU.S.=U.S.LDPE(28.6%)+U.S.HDPE(71.4%)]–[U.S.Ethane].
