NewsRelease TC Energy successfully completes $5.3 billion sale of a 40 per cent non- controlling equity interest in Columbia Gas and Columbia Gulf Proceeds from transaction significantly accelerate deleveraging and deliver key 2023 strategic priority CALGARY, Alberta – Oct. 4, 2023 – News Release – TC Energy Corporation (TSX, NYSE: TRP) (TC Energy or the Company) today announced that it has successfully completed the sale of a 40 per cent non-controlling equity interest in its Columbia Gas Transmission, LLC (Columbia Gas) and Columbia Gulf Transmission, LLC (Columbia Gulf) systems to Global Infrastructure Partners (GIP) for total cash proceeds of $5.3 billion (US$3.9 billion). "This sizable transaction is a tangible example of our team’s focus on achieving one of our key 2023 strategic priorities of significantly advancing our deleveraging goals, ahead of our year-end target,” said François Poirier, TC Energy’s President and Chief Executive Officer. “GIP is a strong and reputable strategic and financial partner that will help unlock incremental value on our Columbia gas systems.” Clear path toward deleveraging • Delivering $5+ billion of cash proceeds in a single transaction is expected to reduce TC Energy’s year-end 2023 debt-to-EBITDAi leverage metric by over 0.4 times, a major step toward reaching its 2024 year-end objective of 4.75 times debt-to-EBITDA. • Demonstrated strong continued access to capital markets in August 2023, with Columbia Pipelines Holding Company LLC (CPHC) and Columbia Pipelines Operating Company LLC (CPOC) initially issuing in aggregate US$5.6 billion of senior unsecured notes. Additional indebtedness is expected to be incurred in 2024 to reach the intended run-rate capital structure. Prior to the closing of the offerings, all US$1.5 billion of existing Columbia Pipeline Group, Inc. (CPG) Senior Notes were assumed by CPOC. • The net proceeds from the offerings were used to repay existing intercompany indebtedness with TC Energy entities and will reduce the Company’s indebtedness or offset future debt issuance such that the offerings are expected to be leverage-neutral to TC Energy on a consolidated basis. • Continuing to evaluate an incremental $3 billion of capital rotation opportunities to achieve the Company’s desired debt-to-EBITDA target. • Limiting sanctioned capital spending, net of partner contributions, to $6 to $7 billion annually, post-2024. Collectively, these actions are expected to enable TC Energy to continue strengthening its balance sheet and reinforce long-term, sustainable, annual dividend growth of three to five per cent. TC Energy will continue to operate the systems, focusing on maximizing value through safe operations, reliability of service and operational excellence. Going forward, GIP will fund its 40 per cent share of Columbia Gas and Columbia Gulf’s gross capital expenditures. Total gross capital expenditures for these assets are expected to average more than $1.3 billion (US$1 billion) annually over the next three years. Transaction details Columbia Pipeline Group, Inc. (CPG) contributed all of its equity interests in its wholly-owned subsidiaries, Columbia Gas and Columbia Gulf, to a newly formed wholly-owned entity, Columbia Pipelines Operating Company, i Debt-to-EBITDA is a non-GAAP ratio. Adjusted debt and adjusted comparable EBITDA are non-GAAP measures used to calculate debt-to-EBITDA.

For more information, visit NON-GAAP MEASURES This release contains references to debt-to-EBITDA. Adjusted debt and adjusted comparable EBITDA are non- GAAP measures used to compute the debt-to-EBITDA multiple. Each of adjusted debt and adjusted comparable EBITDA measures do not have any standardized meaning prescribed by GAAP and therefore, may not be comparable to similar measures presented by other companies. We believe that debt-to-EBITDA provides investors with useful information as it reflects our ability to service our debt and other long-term commitments. Adjusted debt is defined as the sum of Reported total debt, including Notes payable, Long-Term Debt, Current portion of long-term debt and Junior Subordinated Notes, as reported on our Consolidated balance sheet as well as Operating lease liabilities recognized on our Consolidated balance sheet and 50 per cent of Preferred Shares as reported on our Consolidated balance sheet due to the debt-like nature of their contractual and financial obligations, less Cash and cash equivalents as reported on our Consolidated balance sheet and 50 per cent of Junior Subordinated Notes as reported on our Consolidated balance sheet due to the equity-like nature of their contractual and financial obligations. Adjusted comparable EBITDA is calculated as comparable EBITDA excluding Operating lease costs recorded in Plant operating costs and other in our Consolidated statement of income and adjusted for Distributions received in excess of income from equity investments as reported in our Consolidated statement of cash flows which is more reflective of the cash flows available to TC Energy to service our debt and other long-term commitments. See “Reconciliations” for reconciliations of adjusted debt and adjusted comparable EBITDA for the years ended December 31, 2021 and 2022.
