Methanex Provides Update on Natgasoline Refinancing

VANCOUVER, British Columbia, Aug. 20, 2026 (GLOBE NEWSWIRE) — Methanex Corporation (the “Company” or “Methanex”) (TSX: MX) (Nasdaq: MEOH) announced today that Natgasoline LLC, a joint venture with Consolidated Energy Limited in which Methanex holds a 50% equity interest, has priced the issuance of tax-exempt bonds by Mission Economic Development Corporation with a principal amount of $290,950,000 (the “2026 Bonds”), a mandatory tender date of August 1, 2036, and a final maturity date of August 1, 2046. The proceeds of the issuance will be loaned to Natgasoline LLC and used to repay the existing $290,950,000 Natgasoline municipal bonds issued in 2018, which mature in 2031 (the ”2018 Bonds”). The coupon rate on the 2026 Bonds was set at 4.75%. Closing of the bond offering is expected to occur on or about August 28, 2026, subject to customary closing conditions. The 2018 Bonds were subject to a semi-annual amortization through a sinking fund redemption initiated on October 1, 2025.

Dean Richardson, Senior Vice President, Finance and Chief Financial Officer, Methanex Corporation, stated, “We are pleased with this refinancing as it maintains a solid financial base for the Natgasoline joint venture, deferring mandatory amortization payments that were coming due. This will provide the entity with greater flexibility for the use of operating cash flows moving forward, including the potential to deleverage through the repayment of higher-cost borrowings in this entity.”
