Methanex’s Natgasoline refinancing pushes $291m bond principal out to 2046 and removes near-term amortization pressure

Methanex Corporation (NASDAQ: MEOH; TSX: MX) is extending the debt runway at its 50%-owned Natgasoline joint venture after the Texas methanol producer priced $290.95 million of tax-exempt bonds carrying a 4.75% coupon. Proceeds are expected to refinance an equal principal amount of municipal bonds issued in 2018, shifting final maturity from 2031 to 2046 while giving Natgasoline greater flexibility over operating cash generated by the facility.

The new securities are being issued by Mission Economic Development Corporation, with the proceeds loaned to Natgasoline LLC. They have a mandatory tender date of August 1, 2036 and a final maturity date of August 1, 2046, while closing is expected around August 28 subject to customary conditions.

The principal amount itself does not increase through the refinancing: $290.95 million of new bonds replaces $290.95 million of existing bonds. What changes materially is the repayment profile, because the 2018 bonds had already entered a semi-annual sinking-fund amortization schedule beginning in October 2025.

How much financial flexibility does the Natgasoline refinancing create?

At the new 4.75% coupon, $290.95 million of principal implies approximately $13.8 million of annual coupon interest before considering transaction costs or other debt arrangements. The more important effect, however, comes from removing the scheduled principal amortization embedded in the existing bonds rather than from changing the nominal debt balance.

Methanex said the refinancing would defer mandatory amortization payments and give Natgasoline greater flexibility in using operating cash flow. One potential use identified by the company is repayment of higher-cost borrowings elsewhere within the joint venture, which would allow management to prioritize debt according to relative cost rather than follow the sinking-fund schedule attached to the 2018 bonds.

Because Methanex owns 50% of Natgasoline and accounts for the business using the equity method, investors should not treat the entire $290.95 million refinancing as Methanex corporate debt. Methanex nevertheless includes its proportionate share of Natgasoline debt when presenting adjusted debt metrics, making changes in the joint venture’s financing structure relevant to the group’s broader leverage analysis.

At June 30, Methanex reported $3.324 billion of adjusted debt, including $396 million representing its share of debt at equity-accounted associates. The company had reduced that measure from $3.706 billion at the end of 2025, helped by the repayment of the remaining $290 million on its Term Loan A during the second quarter.

Why has Natgasoline become more important to Methanex’s North American portfolio?

Methanex acquired its 50% Natgasoline interest through the OCI Global methanol acquisition completed in June 2025. The transaction expanded Methanex’s North American manufacturing footprint substantially and brought the company into a facility with annual operating capacity equivalent to approximately 850,000 tonnes for Methanex’s 50% share.

That asset has quickly become a meaningful production contributor. Natgasoline produced 204,000 tonnes on a Methanex-equity basis during the second quarter of 2026 and 407,000 tonnes during the first half, compared with only 10,000 tonnes included in the comparable 2025 period because the acquisition closed near the end of June last year.

The contribution helped Methanex report record North American production during the quarter. Group methanol production reached 2.213 million tonnes, including more than one million tonnes from the company’s Geismar operations, while second-quarter adjusted EBITDA surged to $577 million from $220 million in the first quarter as realized methanol pricing increased sharply.

Methanex also generated $439 million of operating cash flow and ended June with $383 million of cash plus an undrawn $400 million revolving credit facility. Against that background, the Natgasoline refinancing is less a sign of immediate liquidity pressure than an attempt to optimize the capital structure of an important joint-venture asset.

What changes after the old 2031 Natgasoline bonds are repaid?

The biggest change is timing. The existing bonds were due in 2031 and had begun amortizing, while the replacement securities carry a 2036 mandatory tender date and 2046 final maturity. That potentially gives the joint venture roughly another decade before the mandatory tender and 15 additional years to final maturity compared with the old 2031 endpoint.

A mandatory tender does mean investors should not interpret 2046 as a guarantee that the existing financing economics remain untouched for two decades. The securities face a significant refinancing or remarketing point in 2036, but even that date materially extends the timetable relative to the bonds being replaced.

The transaction also complements debt reduction occurring elsewhere at Methanex. The company fully repaid its remaining $290 million Term Loan A during the second quarter, cutting consolidated long-term debt while strong methanol pricing boosted earnings and cash generation.

That combination provides a clearer interpretation of the Natgasoline transaction. Methanex is not simply adding another $291 million liability while operating leverage rises; its joint venture is replacing existing debt with a longer-dated instrument at the same principal amount while Methanex itself has been reducing other borrowings.

The ultimate benefit will depend on how Natgasoline uses the cash flow freed from near-term amortization. If that flexibility is directed toward retiring higher-cost debt, the refinancing could lower financing pressure without increasing principal. If cash is instead retained or redeployed, management will need to demonstrate that those uses create more value than accelerated deleveraging.

Either way, the refinancing turns a relatively ordinary bond announcement into a meaningful capital-allocation development. Natgasoline’s debt is not disappearing, but its repayment schedule is becoming substantially less restrictive just as the facility has emerged as an important contributor to Methanex’s enlarged North American production base.
