Methanex Corporation (TSX:MX) (NASDAQ:MEOH) announced today that its Board of Directors unanimously approved two key decisions aligned with its capital allocation priorities:

• A restart of construction on the Company’s advantaged Geismar 3 project, and
• A reset of the quarterly dividend to $0.125 per share from $0.0375 per share

These decisions complement a separate announcement yesterday on an agreement with Mitsui O.S.K. Lines, Ltd. (MOL) on key commercial terms for a strategic shipping partnership. The agreement is expected to realize strategic benefits for our Waterfront Shipping business and unlock $145 million in non-dilutive capital to further strengthen our financial position.

John Floren, President & CEO of Methanex, commented, “We are very pleased to announce these important steps that we believe will deliver long-term value to our shareholders. The timing is right to restart construction on our Geismar 3 project as the methanol industry outlook is positive, we have a strong financial position to fund the project and the project has been significantly de-risked and is well positioned to be completed on-time and on budget. Geismar 3 will strengthen our asset portfolio as it will be one of our lowest cost plants, with access to abundant and low-cost natural gas and have one of the lowest CO2 emissions intensity profiles in the industry.”

“We expect our future cash generation capability will be enhanced by Geismar 3, a unique project with significant capital and operating cost advantages. Geismar 3 is our only major growth capital project expected over the next few years. We are pleased to announce an increase in our dividend, and we expect that Geismar 3 will support a substantial increase in our shareholder distribution potential in the years to come.”

Geismar 3 will benefit from favourable methanol industry fundamentals

Current methanol industry fundamentals are positive as growing methanol demand, low global inventory levels, ongoing industry supply challenges and a rising energy price environment have supported higher methanol prices. Over the medium term, we believe that the industry will need new supply to meet growing methanol demand.

We expect strong methanol demand growth of approximately 16 million tonnes or 20% (~4% CAGR) over the next five years. That compares with just 14 million tonnes of new industry capacity additions over that same period, including Geismar 3. With limited project commitments beyond 2022, industry operating rates will need to increase to meet growing demand.

Strong financial position to restart Geismar 3 construction

We recently completed deleveraging initiatives and credit facility amendments to further strengthen our balance sheet and enhance our financial flexibility:

• Repaid $173 million drawn on our Geismar 3 construction facility;
• Reduced the size of the Geismar 3 construction facility by $200 million to $600 million;
• Extended the maturity date on our $600 million Geismar 3 construction facility to 2025 from 2024; and
• Extended the maturity date on our $300 million revolving credit facility to 2026 from 2024.

These completed credit arrangements supplement the proceeds of $145 million from our strategic shipping partnership with MOL.

As a result, we have a healthy cash balance underpinned by access to $900 million of undrawn backup liquidity beyond the expected Geismar 3 construction period.

Geismar 3 is de-risked, on budget and on-track for commercial operations by late 2023/early 2024

We now estimate the total capital costs for the Geismar 3 project to be $1.25 to $1.35 billion, lower than our prior estimate of $1.3 to $1.4 billion. This revised estimate is based on a significant reduction in the project’s execution risk profile. We expect that approximately $435 million will be committed to the project as of the end of Q3 2021 through the care and maintenance period. We expect approximately $800 to $900 million of remaining capital costs after resuming construction in October 2021.

We plan to fund construction with cash on hand and future cash flow (without incurring incremental debt) at methanol prices of approximately $275 per tonne and higher. In addition, if sustained methanol prices are approximately $325 per tonne or higher, we anticipate that we will have the ability to further de-lever and increase shareholder distributions during the Geismar 3 construction period.

Commercial operations are targeted for the end of 2023 or early 2024.

Consistent capital allocation priorities with emphasis on financial flexibility

Our capital allocation priorities remain unchanged to (1) maintain our business, (2) pursue profitable growth opportunities, and (3) return excess cash to shareholders. Within this framework, we are increasing our emphasis on financial flexibility. This means that we will target higher cash balances, lower leverage and a greater weighting on flexible vehicles for distributions, such as share buybacks, on top of a sustainable dividend. Today, we reset our regular quarterly dividend to $0.125 per share from $0.0375 per share.
