Forward-looking statements in this document are intended to provide TC Energy security holders and potential investors with information regarding TC Energy and its subsidiaries, including management's assessment of TC Energy's and its subsidiaries' future plans and financial outlook. All forward-looking statements reflect TC Energy's beliefs and assumptions based on information available at the time the statements were made and as such are not guarantees of future performance. As actual results could vary significantly from the forward-looking information, you should not put undue reliance on forward-looking information and should not use future-oriented information or financial outlooks for anything other than their intended purpose. We do not update our forward-looking information due to new information or future events, unless we are required to by law.

Non-GAAP Measures This release contains references to debt-to-EBITDA which is a non-GAAP ratio which is calculated using adjusted debt and adjusted comparable EBITDA, both of which are non-GAAP measures. We believe debt-to-EBITDA ratios provide investors with a useful credit measure as they reflect our ability to service our debt and other long-term commitments. These non-GAAP measures do not have any standardized meaning as prescribed by GAAP and therefore may not be comparable to similar measures presented by other entities. These non-GAAP measures are calculated by adjusting certain GAAP measures for specific items we believe are significant but not reflective of our underlying operations in the period. These comparable measures are calculated on a consistent basis from period to period and are adjusted for specific items in each period, as applicable except as otherwise described in the Condensed consolidated financial statements and MD&A.

Comparable EBITDA for Portland Natural Gas Transmission System for the years ended December 31, 2023 and 2022 was US$104 million and US$101 million, respectively. Comparable EBITDA for our U.S. Natural Gas Pipelines segment for the years ended December 31, 2023 and 2022 was US$3.248 billion and US$3.142 billion, respectively. Segmented earnings for our U.S. Natural Gas Pipelines segment for the years ended December 31, 2023 and 2022 were $3.531 billion and $2.617 billion, respectively. For reconciliations of comparable EBITDA to segmented earnings for our U.S. Natural Gas Pipelines segment for the years ended December 31, 2023 and 2022, refer to pages 21, 50 and the Non-GAAP measures section of our management’s discussion and analysis for the year ended December 31, 2023 (the MD&A), which sections of the MD&A are incorporated by reference herein. The MD&A can be found on SEDAR+ (www.sedarplus.ca) under TC Energy's profile.

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.
