The integration is expected to increase run rate production and cash flow. We are focused on leveraging our global expertise and operational experience to improve operating rates and deliver on the strategic value of the acquisition.

Our capital allocation priorities remain focused on maintaining the business through sustaining capital investments and reducing leverage toward our target level. We are committed to maintaining a flexible balance sheet that positions us to pursue strategic initiatives, including high-return growth projects and opportunistic share buybacks.

Global production capacity across 7 production locations

Strategically expanded our North American footprint to capitalize on stable and economic supply of natural gas feedstock

Gas supply: financial hedges, fixed price contracts, and spot market purchases

Gas supply: methanol price linked contracts

The map is intended for illustrative purposes.

1 Annual operating capacity reflects, among other things, average expected plant outages, turnarounds and average age of the facility's catalyst. Actual production for a facility in any given year may be higher or lower than operating capacity due to several factors, including natural gas composition or the age of the facility's catalyst. Methanex's share shown for Natgasoline in Beaumont (50%) and Egypt (50%). Operating capacity excludes plants in Trinidad (Atlas, 63.1% ownership), New Zealand (Motunui 1 and Waitara Valley) and Netherlands (Delfzil) as these plants have been idled as they do not currently

7 have access to an economic gas supply to operate. Capacity shown is for methanol unless stated otherwise.
