In 2023, invested more than $15 million of capital into energy efficiency and reliability projects with GHG reduction benefits at existing sites. Reduced-intensity Expansion Projects The G3 plant in Geismar, Louisiana, is expected to start up in 2024 and will have one of the lowest emission intensity profiles in the industry. Low Carbon Projects Invested close to $1 million on feasibility studies for carbon capture and storage (CCS) in 2023, which allowed us to refine the potential scope and increase certainty around key assumptions required to progress a project into Pre-FEED. Renewable Natural Gas Using renewable natural gas or biomass in a conventional methanol process results ina form of green methanol called bio-methanol. E-methanol Production Exploring opportunities and conducting feasibility studies to use renewable electricity to produce green hydrogen and combine this with industrial or biogenic CO₂ from third parties to produce e-methanol. The upgrades from projects completed in 2022 and 2023 will help avoid ~60,000 tonnes CO₂ e per year. Estimated G3 intensity of <0.30 tonnes of CO₂/tonne of methanol, which will lower our average emissions intensity. Committed to advance at least one low-carbon project into Pre- FEED (Preliminary Front End Engineering and Design) in 2024. Certified by the ISCC to produce bio-methanol in Geismar, enabling sales to European fuel customers underthe Renewable Energy Directive II (RED II). Plan to further explore the feasibility of e-methanol specifically at our Geismar, U.S., and Damietta Egypt sites in 2024.

For historical Adjusted EBITDA, refer Additional Information - Non-GAAP Measures in the Company's 2023 Annual MD&A. For historical Free cash flow, refer to footnote 3. 2 Adjusted EBITDA is a forward-looking non-GAAP measure and reflects Methanex's proportionate ownership interest. We target to hedge ~70% of our North American natural gas requirements. The unhedged portion of our North American natural gas requirements are purchased under contracts at spot prices. Estimates assume Henry Hub natural gas price of ~$3.50/mmbtu based on near-term forward curve. 3 Free cash flow is a forward-looking non-GAAP measure and reflects Methanex's proportionate ownership interest. Free cash flow is presented after lease payments, cash interest (based on current debt levels), debt service, maintenance capital, estimated cash taxes and other cash payments. Various factors such as rising/declining methanol prices, planned and unplanned production outages, production mix, changes in tax rates, and other items that can impact actual Free cash flow. Incremental free cash flow from G3 is presented with zero cash tax due to the significant tax shelter available to it. Free cash flow, both historical and forward-looking, is useful as it provides a measure of our cashflow generation capability and differs from the most comparable GAAP measure, Increase (decrease) in cash and cash equivalents, as it is adjusted to include out proportional share of the Atlas joint venture cashflows and to exclude the non-controlling interests share of Egypt and Waterfront Shipping, with dividends and repurchase of shares added back. This non-GAAP measure does not have any standardized meaning prescribed by GAAP and therefore, is unlikely to be comparable to a similar measure presented by other companies. 32 Methanex | The Global Methanol Leader | Investor Presentation March 2024 APPENDIX methanex the power of agility#33methanex the power of agility Investor Relations T: 604 661 2600 [email protected] www.methanex.com in linkedin.com/company/methanex-corporation @Methanex Methanex | The Global Methanol Leader | Investor Presentation March 2024
