3.NEWS RELEASE

The news release announcing the material change described herein was issued and disseminated on January 7, 2021 in Canada and the United States through the facilities of a newswire service.

4. SUMMARY OF MATERIAL CHANGE

Methanex Corporation (the “Company”) announced on January 7, 2021 that it expects its Titan methanol facility in Trinidad (875,000 annual operating capacity) will remain idled indefinitely.

5. FULL DESCRIPTION OF MATERIAL CHANGE

5.1 FULL DESCRIPTION OF MATERIAL CHANGE

Methanex Corporation announced that it expects its Titan methanol facility (“Titan”) in Trinidad (875,000 annual operating capacity) will remain idled indefinitely. As a result, the Company has made the decision to restructure its Trinidad operations to support a one-plant operation and reduce its Trinidad workforce by approximately 60 positions filled by employees and long-term contractors.

To date, the Company has not been successful reaching an agreement for an

economic longer-term natural gas agreement and given that the economic recovery path remains uncertain it believes it is prudent to reduce costs while continuing its efforts to secure longer-term gas supply. The Atlas methanol facility (Methanex interest 63.1%) is not affected by the change and continues to operate as it is underpinned by a separate natural gas supply agreement that expires in 2024.
