Although we believe these forward - looking statements are reasonable based on the information available on the date such statemen ts are made and processes used to prepare the information, such statements are not guarantees of future performance and reade rs are cautioned against placing undue reliance on forward - looking statements. By their nature, these statements involve a variety of assumptions, known and unknown risks and uncertainties and ot her factors, which may cause actual results, levels of activity and achievements to differ materially from those expressed or im plied by such statements. Material assumptions include assumptions about the following: the expected supply of, demand for, export of and prices of crude oil, natural gas, NGL, LNG and renewable energy; en ergy transition, including the drivers and pace thereof; anticipated utilization of assets; exchange rates; inflation; intere st rates; availability and price of labor and construction materials; the stability of the our supply chain; operational reliability; maintenance of support and regulatory approvals for the Enbridge’s projects; anticipat ed in - service dates; weather; the timing, terms and closing of acquisitions and dispositions, including the Acquisitions, and of th e financing of the Acquisitions; the realization of anticipated benefits of transactions, including the Acquisitions; governmental legislation; litigation; estimated future dividends and impact of Enbridge’s dividen d p olicy on its future cash flows; our credit ratings; capital project funding; hedging program; expected EBITDA and adjusted EB ITD A; expected earnings/(loss) and adjusted earnings/(loss); expected future cash flows; expected future EPS; expected DCF and DCF per share; debt and equity market conditions; and the ability of management to execute key priorities, including with respect to the Acquisitions. Assumptions regarding the expected supply of and demand f or crude oil, natural gas, NGL, LNG and renewable energy, and the prices of these commodities, are material to and underlie all forward - looking statements, as they may impact current and future levels of demand for the Enbridge’s services. Similarly, exchange rates, inflation and interest rates impact the economies and business en vironments in which Enbridge operates and may impact levels of demand for our services and cost of inputs, and are therefore inherent in all forward - looking statements. The most relevant assumptions ass ociated with forward - looking statements regarding announced projects and projects under construction, including estimated comple tion dates and expected capital expenditures, include the following: the availability and price of labor and construction materials; the stability of our supply chain; the effects of inflation and f ore ign exchange rates on labor and material costs; the effects of interest rates on borrowing costs; and the impact of weather a nd customer, government, court and regulatory approvals on construction and in - service schedules and cost recovery regimes. Our forward - looking statements are subject to risks and uncertainties pertaining to the successful execution of our strategic pr iorities, operating performance, legislative and regulatory parameters; litigation; acquisitions (including the Acquisitions) , d ispositions and other transactions and the realization of anticipated benefits therefrom; the financing of the Acquisitions; operational dependence on third parties; dividend policy; project approval and support; re new als of rights - of - way; weather; economic and competitive conditions; public opinion; changes in tax laws and tax rates; exchange rates; inflation; interest rates; commodity prices; access to and cost of capital; political decisions; global geopolitical conditions; and the supply of, demand for and prices of commodities and other altern ati ve energy, including but not limited to those risks and uncertainties discussed in our filings with Canadian and United State s s ecurities regulators. The impact of any one assumption, risk, uncertainty or factor on a particular forward - looking statement is not determinable with certainty as these are interdependent and the our future cour se of action depends on management’s assessment of all information available at the relevant time. Financial outlook and future oriented financial information contained in this presentation about prospective financial perfor man ce, financial position or cash flows is based on assumptions about future events, including economic conditions and proposed cou rses of action, based on management’s assessment of the relevant information currently available and is subject to the same risk factors, limitations and qualifications as set forth above. The financial in formation included in this presentation, has been prepared by, and is the responsibility of, management . The purpose of the fin ancial outlook and future oriented financial information provided in this presentation is to assist readers in understanding the Enbridge’s expected financial results following completion of the Acquisitions and the as sociated financings, and may not be appropriate for other purposes. Enbridge and its management believe that such financial i nfo rmation has been prepared on a reasonable basis, reflecting the best estimates and judgments, and that prospective financial information represents, to the best of management’s knowledge and opinion, Enbr idg e’s expected course of action. However, because this prospective information is highly subjective, it should not be relied on as necessarily indicative of past or future results, as the actual results may differ materially from those set forth in this presentation. Except to the extent required by applicable law, Enbridge assumes no obligation to publicly update or revise any forward - looking statement made in this presentation or otherwise, whether as a result of new information, future events or otherwise. All for wa rd - looking statements, whether written or oral, attributable to Enbridge or persons acting on its behalf, are expressly qualified in their entirety by these cautionary statements. Non - GAAP Measures This presentation makes reference to non - GAAP and other financial measures, including earnings before interest, income taxes, de preciation and amortization (EBITDA), adjusted EBITDA, adjusted earnings and adjusted earnings per share (EPS), distributable ca sh flow (DCF) and DCF per share and debt to EBITDA. Management believes the presentation of these metrics gives useful information to investors and shareholders as they provide increased t ran sparency and insight into the performance of the Company. Adjusted EBITDA represents EBITDA adjusted for unusual, infrequent or other non - operating factors on both a consolidated and segmented basis. Management uses EBITDA and adjusted EBITDA to set targets and to assess the performance of the Company and its business units . A djusted earnings represent earnings attributable to common shareholders adjusted for unusual, infrequent or other non - operating factors included in adjusted EBITDA, as well as adjustments for unusual, infrequent or other non - operating factors in respect of depreciation and amortization expense, interest expense, income taxes and non - controlling interests on a consolidated basis. Management uses adjusted earnings as another measure of the Compan y’s ability to generate earnings and uses EPS to assess the performance of the Company. DCF is defined as cash flow provided by operating activities before the impact of changes in operating assets an d liabilities (including changes in environmental liabilities) less distributions to non - controlling interests, preference share dividends and maintenance capital expenditures, and further adjusted for unusual, infrequent or other non - operating factors. Management also uses DCF to assess the performance of the Company and to set its divi dend payout target. Debt to EBITDA is used as a liquidity measure to indicate the amount of adjusted earnings available to pay debt (as calculated on a GAAP basis) before covering interest, tax, depreciation and amortization. Reconciliations of forward - looking non - GAAP and other financial measures to comparable GAAP measures are not available due to th e challenges and impracticability of estimating certain items, particularly certain contingent liabilities and non - cash unrealiz ed derivative fair value losses and gains which are subject to market variability. Because of those challenges, reconciliations of forward - looking non - GAAP and other financial measures are not available without unreasonable effort. The non - GAAP measures described above are not measures that have standardized meaning prescribed by generally accepted accountin g principles in the United States of America (U.S. GAAP) and are not U.S. GAAP measures. Therefore, these measures may not be co mparable with similar measures presented by other issuers. Additional information on non - GAAP and other financial measures may be found in the Company’s earnings news releases or in addit ional information on the Company’s website, www.sedarplus.com or www.sec.gov.

The impact of any one assumption, risk, uncertainty or factor on a particular forward - looking statement i s not determinable with certainty as these are interdependent and Enbridge’s future course of action depends on management’s ass essment of all information available at the relevant time. Financial outlook and future - oriented financial information contained in this presentation about prospective financial performan ce, financial position or cash flows is based on assumptions about future events, including economic conditions and proposed cou rses of action, based on management’s assessment of the relevant information currently available and is subject to the same risk factors, limitations and qualifications as set f ort h above. The financial information included in this presentation, has been prepared by, and is the responsibility of, managem ent . The purpose of the financial outlook and future - oriented financial information provided in this presentation is to assist readers in understanding Enbridge’s expected financial resul ts following completion of the Transaction and the associated financings, and may not be appropriate for other purposes. Enbridg e a nd its management believe that such financial information has been prepared on a reasonable basis, reflecting the best estimates and judgments, and that prospective financial informat ion represents, to the best of management’s knowledge and opinion, Enbridge’s expected course of action. However, because this pr os pective information is highly subjective, it should not be relied on as necessarily indicative of past or future results, as the actual results may differ materially from those set for th in this presentation. Except to the extent required by applicable law, Enbridge assumes no obligation to publicly update or revise any forward - looking statement made in this presentation or otherwise, whether as a result of new information, future events or otherwise. All for wa rd - looking statements, whether written or oral, attributable to it or persons acting on Enbridge’s behalf, are expressly qualified in their entirety by these cautionary statements. Non - GAAP Measures This presentation makes reference to non - GAAP and other financial measures, including earnings before interest, income taxes, de preciation and amortization (EBITDA), adjusted EBITDA, adjusted earnings and adjusted earnings per share (EPS), distributable ca sh flow (DCF) and DCF per share and debt to EBITDA. Management believes the presentation of these metrics gives useful information to investors and shareholders as they pro vide increased transparency and insight into the performance of the Company. Adjusted EBITDA represents EBITDA adjusted for u nus ual, infrequent or other non - operating factors on both a consolidated and segmented basis. Management uses EBITDA and adjusted EBITDA to set targets and to assess the performa nce of the Company and its business units. Adjusted earnings represent earnings attributable to common shareholders adjusted for un usual, infrequent or other non - operating factors included in adjusted EBITDA, as well as adjustments for unusual, infrequent or other non - operating factors in respect of depreciation and amortization expense, interest expense, income taxes and non - controlling interests on a consolidated basis. Ma nagement uses adjusted earnings as another measure of the Company’s ability to generate earnings and uses EPS to assess the performance of the Company. DCF is defined as cash flow pr ovided by operating activities before the impact of changes in operating assets and liabilities (including changes in environ men tal liabilities) less distributions to non - controlling interests, preference share dividends and maintenance capital expenditures, and further adjusted for unusual, infrequent or o the r non - operating factors. Management also uses DCF to assess the performance of the Company and to set its dividend payout target . Debt to EBITDA is used as a liquidity measure to indicate the amount of adjusted earnings available to pay debt (as calculated on a GAAP basis) before covering interest, tax, de preciation and amortization. Reconciliations of forward - looking non - GAAP and other financial measures to comparable GAAP measures are not available due to th e challenges and impracticability of estimating certain items, particularly certain contingent liabilities and non - cash unrealiz ed derivative fair value losses and gains which are subject to market variability. Because of those challenges, reconciliations of forward - looking non - GAAP and other financial meas ures are not available without unreasonable effort. The non - GAAP measures described above are not measures that have standardized meaning prescribed by generally accepted accountin g principles in the United States of America (U.S. GAAP) and are not U.S. GAAP measures. Therefore, these measures may not be co mparable with similar measures presented by other issuers. Additional information on non - GAAP and other financial measures may be found in the Company’s earnings news re leases or in additional information on the Company’s website, www.sedarplus.com or www.sec.gov.
