The Power of Agility

21 Geismar 3 is an industry-leading plant Optimizing efficiency and reducing emissions intensity through synergistic design Investment strategy Meeting growing demand for methanol Significant capital and operating cost savings from brownfield site advantages generates strong project returns and cash flow generation One of the lowest CO2 emissions intensity profiles in the industry at ~0.4 tonnes of CO2/tonne of methanol compared to our portfolio intensity of 0.6 which is ~5 times lower than a coal-based methanol plant Significantly de-risked during care and maintenance period; all major equipment items are onsite Key milestones Broke ground September 2019; project put on care and maintenance Q2 2020 to Q3 2021 due to the pandemic; restarted construction in August 2021 ~50% complete as of February 28, 2022 Q2 • - Q4 2022 Pipe rack installation • Tank erection • • Foundations Electrical + instrumentation 2023 • • HV power energized Utility systems commissioned Oxygen available Mechanical completion Project highlights 1.8 mmt methanol plant located adjacent existing Geismar 1 and 2 plants Capital spend $1.25-1.35 billion $625 725 million of remaining capital costs (as of Q1 2022) Commercial production by end of 2023/early 2024 methanex the power of agility
