VANCOUVER, BRITISH COLUMBIA—(Marketwire – April 23, 2008) – Methanex Corporation (TSX:MX)(NASDAQ:MEOH)(SANTIAGO:Methanex) – For the first quarter of 2008, Methanex reported Adjusted EBITDA(1) of $127 million, net income of $65 million and earnings per share of $0.67 (on a diluted basis).

Bruce Aitken, President and CEO of Methanex commented, “Our average realized price in the first quarter was $545 per tonne which resulted in another good quarter of earnings for our shareholders. Our earnings under this pricing environment would normally be higher, however, we sourced less of our sales from produced methanol during the first quarter and more from purchased methanol and this had an impact on our profitability. In addition, methanol pricing peaked in December and decreased through the first quarter and, as is typical in a decreasing methanol price environment, our sales margins on both produced and purchased methanol are impacted by inventory timing issues.”

Mr. Aitken added, “In the high methanol price environment of the last six months, we saw China moving from being a net importer to a net exporter, which we believe has been the most significant factor causing the methanol market to rebalance and methanol prices to decline. We have also seen some regional softness in demand in some derivatives, but globally we continue to observe that demand for methanol is healthy and the high energy price environment continues to underpin strong demand growth for new methanol demand in energy applications, particularly in DME and fuel blending in China.”

Mr. Aitken continued, “China has recently reverted to being a net importer and spot methanol prices are increasing. We are continuing to make good progress on our initiatives to source more gas in Chile and we recently agreed to terms on a gas supply arrangement in New Zealand which will allow us to switch production to one of our larger idle plants in the second half of the year.”

Mr. Aitken concluded, “Our strong cash generation in the first quarter continues to leave us in a strong financial position. With US$465 million cash on hand at the end of the quarter, a strong balance sheet and a US$250 million undrawn credit facility, we are well positioned to meet our financial commitments related to the Egypt methanol project, pursue opportunities to accelerate natural gas development in southern Chile, pursue opportunities to sponsor methanol demand in new energy applications, pursue other strategic growth initiatives, and continue to deliver on our commitment to return excess cash to shareholders.”
