CALGARY, Alberta, Sept. 21, 2026 (GLOBE NEWSWIRE) -- TC Energy Corporation (TSX, NYSE: TRP) (TC Energy or the Company) today announced it has entered into an agreement to sell Energía Occidente de México (EOM), the entity that owns the Guadalajara-Manzanillo Pipeline, to affiliates of ESENTIA Energy Development, S.A.B. de C.V. (ESENTIA) for a gross purchase price of $560 million (US$400 million). The 313-kilometre Guadalajara-Manzanillo Pipeline transports up to 500 MMcf/d of natural gas, connecting imported LNG supply near Manzanillo and continental gas supply near Guadalajara to power plants and industrial customers in the states of Colima and Jalisco.

This transaction is anticipated to close in the first half of 2027, and is subject to customary closing conditions, regulatory approvals and consents.

"This transaction reflects our continued focus on portfolio optimization and long-term value creation," said François Poirier, President and Chief Executive Officer of TC Energy. "The transaction will support our disciplined capital allocation strategy, creating optionality to redeploy proceeds from a mature asset towards high-value growth opportunities across our North American footprint. With more than 30 years of history in Mexico, and as the largest Canadian investor in the country, TC Energy remains committed to reliably delivering the natural gas that supports the country's expanding energy needs, strengthens energy security and enables future economic development.”

TC Energy and ESENTIA will work together to support a safe and orderly transition of operations of this critical natural gas system.

Following closing, TC Energy will continue to own and operate its broader Mexico natural gas pipeline network, including approximately 3,300 kilometres of pipeline and 8.7 Bcf/d of installed natural gas transportation capacity.
