Investor Presentation October 2023

Price response required to incentivize new low-carbon methanol production We expect government policies and regulations to lead to increased investment and demand for low and zero carbon methanol. Greater production of lower or zero carbon methanol can be incentivized through various means including customers' willingness to pay a higher price and new technology that reduce production costs. The cost for lower emission methanol is expected to decrease as technologies mature and become scalable.
