• Net income attributable to Methanex shareholders of $69 million and Adjusted EBITDA of $192 million.
• Geismar 3 ("G3") project progressing on time and on budget. First methanol production expected in the fourth quarter of 2023. The remaining capital of approximately $450 to $500 million is fully funded with cash on hand.
• Increased the quarterly dividend by 20% in July and announced the approval of a 5% share repurchase program in September.
• Successfully completed scheduled turnarounds in New Zealand and Egypt. The timing of the Egypt turnaround enabled an agreement to redirect and sell the plant's contracted natural gas for three months to utilize excess LNG capacity in Egypt to serve energy demand in Europe.
• Returned $44 million to shareholders through dividends and share repurchases and have a strong liquidity position with $962 million in cash.

For the third quarter of 2022, Methanex (TSX:MX) (NASDAQ:MEOH) reported net income attributable to Methanex shareholders of $69 million ($0.87 net income per common share on a diluted basis) compared to net income of $125 million ($1.41 net income per common share on a diluted basis) in the second quarter of 2022. Net income was lower compared to the prior quarter primarily due to a lower average realized price, lower sales of Methanex-produced methanol attributable to the planned turnarounds in Egypt and New Zealand and the mark-to-market impact of share-based compensation due to changes in Methanex's share price. This was partially offset by the redirection and sale of natural gas in Egypt. Adjusted EBITDA for the third quarter of 2022 was $192 million, and Adjusted net income was $49 million ($0.69 Adjusted net income per common share). This compares with Adjusted EBITDA of $243 million and Adjusted net income of $84 million ($1.16 Adjusted net income per common share) for the second quarter of 2022.

The average realized price in the third quarter was $377 per tonne compared to $422 per tonne in the second quarter of 2022. Methanol pricing moderated from early year highs and stabilized in the third quarter with flat demand coupled with lower industry operating rates due to turnarounds and planned and unplanned outages impacting supply.

We returned $44 million to shareholders through the regular dividend and share repurchases and ended the quarter with $962 million in cash, or approximately $890 million in cash excluding non-controlling interests and including our share of cash in the Atlas joint venture. We also have two undrawn credit facilities, a $300 million construction credit facility specifically related to the Geismar 3 project and a $300 million revolving credit facility providing financial flexibility.

John Floren, President & CEO of Methanex, said, “Heading into the fourth quarter we are pleased to see stable demand and firm methanol prices. Methanol is an essential chemical building block and the long-term fundamentals of the methanol industry remain strong. The team is focused on delivering the fully funded G3 project on time and on budget in the fourth quarter of 2023. We remain committed to our disciplined capital allocation strategy and are well positioned with a strong balance sheet to navigate the current macro economic uncertainty and continue to return excess cash through dividends and share buybacks."

FINANCIAL AND OPERATIONAL DATA

A reconciliation from net income attributable to Methanex shareholders to Adjusted EBITDA, Adjusted net income and the calculation of Adjusted net income per common share is as follows:

• We recorded net income attributable to Methanex shareholders of $69 million in the third quarter of 2022 compared to net income of $125 million in the second quarter of 2022. Net income was lower compared to the prior quarter primarily due to a lower average realized price, lower sales of Methanex-produced methanol attributable to the planned turnarounds in Egypt and New Zealand and the mark-to-market impact of share-based compensation due to changes in Methanex's share price. This was partially offset by redirecting and selling our contracted natural gas in Egypt.
• We recorded Adjusted EBITDA of $192 million for the third quarter of 2022 compared to $243 million for the second quarter of 2022. We recorded Adjusted net income of $49 million for the third quarter of 2022 compared to Adjusted net income of $84 million for the second quarter of 2022. Adjusted EBITDA and Adjusted net income for the third quarter of 2022 were lower than the second quarter of 2022 primarily due to a lower average realized price and lower sales of Methanex-produced methanol, which was partially offset by redirecting and selling our contracted natural gas in Egypt.
• We sold 2,677,000 tonnes in the third quarter of 2022 compared to 2,692,000 tonnes for the second quarter of 2022. Sales of Methanex-produced methanol were 1,350,000 tonnes in the third quarter of 2022 compared to 1,634,000 tonnes in the second quarter of 2022.
• Production for the third quarter of 2022 was 1,252,000 tonnes compared to 1,551,000 tonnes for the second quarter of 2022. Production was lower for the third quarter of 2022 primarily due to planned turnarounds in Egypt and New Zealand, seasonal gas restrictions in Chile and unplanned outages in Geismar and Medicine Hat.
• We had lower levels of production from Egypt in the third quarter as we completed an extended planned turnaround. The timing of the turnaround enabled us to enter into an agreement to redirect and sell the plant's contracted natural gas, from late July to late October. This was a unique opportunity to utilize excess LNG capacity in Egypt during a period of elevated LNG prices in Europe and was done in collaboration with our Egyptian government partners. We estimate that the sale and redirection of our gas resulted in an incremental benefit to the third quarter of approximately $35 million, compared to using this gas for the production of methanol for the period the plant was not scheduled to be under turnaround. The plant is currently in the process of restarting.
• The highly advantaged Geismar 3 project is progressing well and on budget with first methanol production expected in the fourth quarter of 2023 with an expected total capital cost of $1.25 - 1.3 billion. The remaining capital of approximately $450 to $500 million is fully funded with cash on hand. Geismar 3 has one of the lowest CO2 emissions intensity profiles in the industry and will enhance our current asset portfolio and help us meet our commitment to reduce our greenhouse gas emissions intensity.
• On July 26, 2022 we completed the normal course issuer bid initiated on September 24, 2021, repurchasing 6,094,171 common shares for a total cost of $282 million. On September 21, 2022 we announced a new normal course issuer bid to repurchase up to 3,506,405 common shares through September 25, 2023. To September 30, 2022, we have repurchased 58,443 common shares for $2 million under the current bid.
• In July 2022, we increased the quarterly dividend by 20% to $0.175 per common share for a total of $12.3 million paid during the third quarter of 2022.
• At September 30, 2022, we have a strong liquidity position including a cash balance of $962 million. We also have two undrawn credit facilities, a $300 million construction credit facility specifically related to the Geismar 3 project and a $300 million revolving credit facility providing financial flexibility.

PRODUCTION HIGHLIGHTS

Key production and operational highlights during the third quarter and production outlook for 2022 include:

• New Zealand produced 205,000 tonnes compared to 244,000 tonnes in the second quarter of 2022. In New Zealand, our production was lower in the third quarter of 2022 compared to the second quarter of 2022 due to a turnaround of the Motunui 1 plant, while the Motunui 2 plant experienced lower operating rates due to lower gas availability from the Maui gas field. Based on production to date and our outlook for natural gas in New Zealand, we estimate production for 2022 to be approximately 1.2 to 1.3 million tonnes.
• The Geismar facilities produced 492,000 tonnes in the third quarter compared to 556,000 tonnes in the second quarter of 2022. Lower production was due to unplanned outages in July and late September. Both Geismar 1 and 2 remained offline at the start of the fourth quarter as the utilities supplier for the Geismar site experienced a loss of power due to a failed transformer during which we took the opportunity to advance some critical G3 tie-ins. Both plants have now restarted.
• Atlas produced 249,000 tonnes (Methanex interest) in both the third and second quarters of 2022. Titan remains idled indefinitely.
• Chile produced 141,000 tonnes in the third quarter of 2022 compared to 197,000 tonnes in the second quarter of 2022. Production for the third quarter of 2022 was lower than the second quarter of 2022 as the Chile IV plant was shut down during the third quarter due to seasonal gas limitations during the Southern hemisphere winter months, when domestic natural gas demand is high. Chile IV restarted in October. We estimate Chile production in 2022 to be approximately 0.9 million tonnes.
• Egypt produced 70,000 tonnes (Methanex interest - 35,000 tonnes) in the third quarter of 2022 compared to 300,000 tonnes (Methanex interest - 150,000 tonnes) in the second quarter of 2022. We had lower levels of production from Egypt in the third quarter as we completed an extended planned turnaround. The timing of the turnaround enabled us to enter into an agreement to redirect and sell the plant's contracted natural gas, from late July to late October, to utilize excess LNG capacity in Egypt to serve energy demand in Europe. The plant is currently in the process of restarting.
• Medicine Hat produced 130,000 tonnes in the third quarter of 2022 compared to 155,000 tonnes in the second quarter of 2022. Production for the third quarter of 2022 was lower compared to the second quarter due an unplanned outage in July.
