TC Energy reports record 2019 financial results

Increases common share dividend by 8 per cent

CALGARY, Alberta – February 13, 2020 – TC Energy Corporation (TSX, NYSE: TRP) (TC Energy or the Company) today announced net income attributable to common shares for fourth quarter 2019 of $1.1 billion or $1.18 per share compared to net income of $1.1 billion or $1.19 per share for the same period in 2018. For the year ended December 31, 2019, net income attributable to common shares was $4.0 billion or $4.28 per share compared to net income of $3.5 billionor $3.92 per share in 2018. Comparable earnings for fourth quarter 2019 were $970 million or $1.03 per common share compared to $946 million or $1.03 per common share for the same period in 2018. For the year ended December 31, 2019, comparable earnings were $3.9 billion or $4.14 per common share compared to $3.5 billion or $3.86 per common share in 2018. TC Energy's Board of Directors also declared a quarterly dividend of $0.81 per common share for the quarter ending March 31, 2020, equivalent to $3.24 per common share on an annualized basis, an increase of eight per cent. This is the twentieth consecutive year the Board has raised the dividend.

"We are very pleased with the performance of our diversified portfolio of regulated and long-term contracted assets which generated record financial results again in 2019," said Russ Girling, TC Energy’s President and Chief Executive Officer. "Despite significant asset sales that accelerated the strengthening of our balance sheet, comparable earnings per share increased seven per cent compared to 2018 while comparable funds generated from operations of $7.1 billion were nine per cent higher. The increases reflect the strong performance of our legacy assets and contributions from approximately $8.7 billion of growth projects that entered service in 2019. Those increases were partially offset by lower contributions from approximately $3.4 billion of assets that were monetized during the year."

TC Energy exited 2019 having attained targeted credit metrics and in a position to fund its $30 billion portfolio of secured growth projects without the issuance of additional common shares. The Company's strong financial position will be further bolstered by the completion of pending portfolio management and project financing expected in the first half of 2020.

In July 2019, the Company entered into an agreement to sell its Ontario natural gas-fired power plants including Napanee, Halton Hills and a 50 per cent interest in Portlands Energy Centre for approximately $2.87 billion. The transaction is anticipated to close by the end of first quarter 2020.

In December 2019, the Company also entered into an agreement to sell a 65 per cent equity interest in its $6.6 billion Coastal GasLink Pipeline Project. Under the terms of the sale, TC Energy will receive upfront proceeds that include reimbursement of its partners' proportionate share of the project costs incurred to the date of close as well as additional payment streams through construction and operation of the pipeline. Concurrent with the sale, the Company expects that Coastal GasLink will finalize a secured construction credit facility with a syndicate of banks to fund up to 80 per cent of the project's capital expenditures during construction. Both transactions are expected to close in the first half of 2020 and substantially satisfy the Company's funding requirements through project completion. TC Energy will continue to be responsible for constructing and operating the pipeline.

"Over the past several years, we have taken significant steps to high-grade our asset base through organic growth, acquisitions and divestitures, as well as return our balance sheet to its position of historical strength," added Girling. "The Company's footprint is comprised of irreplaceable corridors of critical energy infrastructure that are expected to contribute to the continuous replenishment of our growth portfolio in the years ahead. Management remains focused on further enhancing the quality and longevity of the Company's earnings and cash flow profile by seeking to turn our remaining merchant revenues into contracted annuity streams as well as increase regulatory certainty through long-term settlements with our customers."

Looking forward, TC Energy will continue to progress more than $20 billion of projects under development including Keystone XL and the Bruce Power life extension program. Success in advancing these and other organic growth opportunities emanating from our five operating businesses across North America, along with our $30 billion secured capital program, is expected to support annual dividend growth of eight to 10 per cent in 2021 and five to seven per cent thereafter.

Net income attributable to common shares for the three months ended December 31, 2019 was $1.1 billion or $1.18 per share compared to $1.1 billion or $1.19 per share for the same period last year. For the year ended December 31, 2019, net income attributable to common shares was $4.0 billion or $4.28 per share compared to $3.5 billion or $3.92 per share in 2018. Per share results reflect the dilutive impact of common shares issued under our Corporate At-The-Market (ATM) program in 2018 and under our DRP. Net income attributable to common shares includes a number of specific items that we believe are significant but not reflective of our underlying operations in the period. More information on these items which are excluded from comparable earnings can be found in the table entitled "Reconciliation of net income to comparable earnings" later in the document.

Comparable EBITDA decreased by $138 million to $2.3 billion for the three months ended December 31, 2019 compared to the same period in 2018 primarily due to the net effect of the following:

• lower contribution from Canadian Natural Gas Pipelines primarily reflecting lower flow-through income taxes and depreciation as well as lower incentive earnings in the Canadian Mainline due to recording the full-year impact of the Canadian Mainline 2018-2020 Tolls Review (NEB 2018 Decision) in fourth quarter 2018. Due to the flow-through treatment of certain expenses including income taxes and depreciation on our Canadian rate-regulated pipelines, the decrease in these expenses impacts our comparable EBITDA despite having no significant effect on net income

• lower contribution from Liquids Pipelines primarily due to decreased volumes on the Keystone Pipeline System, lower margins on liquids marketing activities and the impact of the sale of an 85 per cent equity interest in Northern Courier on July 17, 2019

• higher contribution from U.S. Natural Gas Pipelines mainly due to incremental earnings from Columbia Gas growth projects placed in service, partially offset by decreased earnings from the sale of certain Columbia midstream assets on August 1, 2019 and from Bison (wholly owned by TC PipeLines, LP) following a 2018 agreement with two customers to pay out their future contract revenues and terminate the contracts

• higher contribution from Power and Storage primarily due to increased Bruce Power results from a higher realized power price and higher volumes, partially offset by lower results from our Alberta cogeneration plants and the sale of the Coolidge generating station on May 21, 2019

• higher equity earnings from our investment in the Sur de Texas pipeline which was placed in service in September 2019, at which time we began recording equity income from operations. Prior to in-service, Sur de Texas equity income primarily reflected an allowance for funds used during construction (AFUDC), net of our proportionate share of interest expense on inter-affiliate loans from its partners. Our share of this interest expense is fully offset in Interest income and other.

Comparable earnings increased by $24 million to $970 million for the three months endedDecember 31, 2019 compared to the same period in 2018 and were primarily due to the net effect of:

• changes in comparable EBITDA described above

• higher interest income and other as a result of lower realized losses in 2019 compared to 2018 on derivatives used to manage our net exposure to foreign exchange rate fluctuations on U.S. dollar-denominated income

• lower income tax expense primarily due to lower flow-through income taxes in Canadian rate-regulated pipelines and lower comparable earnings before income taxes, partially offset by lower foreign tax rate differentials

• lower depreciation largely in Canadian Natural Gas Pipelines which is fully recovered in tolls as reflected in comparable EBITDA above, therefore having no significant impact on comparable earnings. This was partially offset by increased depreciation in U.S. Natural Gas Pipelines reflecting new projects placed in service

• lower AFUDC primarily due to Columbia Gas and Columbia Gulf growth projects placed in service, partially offset by capital expenditures on our NGTL System and continued investment in our Mexico projects.

Comparable earnings per common share for the three months ended December 31, 2019 was consistent with 2018 at $1.03 and reflects the dilutive impact of common shares issued under our DRP in fourth quarter 2018 and throughout 2019.

Comparable EBITDA in 2019increased by $803 million to $9.4 billion compared to the same period in 2018 primarily due to the net effect of the following:

• increased contribution from U.S. Natural Gas Pipelines mainly attributable to incremental earnings from Columbia Gas and Columbia Gulf growth projects placed in service, partially offset by decreased earnings from Bison (wholly owned by TC PipeLines, LP) contract terminations and from the sale of certain Columbia midstream assets on August 1, 2019

• increased contribution from Liquids Pipelines primarily resulting from higher volumes on the Keystone Pipeline System and earnings from liquids marketing activities, partially offset by decreased earnings as a result of the sale of an 85 per cent equity interest in Northern Courier on July 17, 2019

• higher contribution from Power and Storage primarily attributable to increased Bruce Power results from a higher realized power price, partially offset by the sale of our interests in the Cartier Wind power facilities in late 2018 and the sale of the Coolidge generating facility on May 21, 2019

• lower contribution from Canadian Natural Gas Pipelines mainly due to lower flow-through income taxes on the Canadian Mainline reflecting the impact of the NEB 2018 Decision and on the NGTL System as a result of accelerated tax depreciation, enacted by the Canadian federal government, partially offset by higher rate base earnings and depreciation on the NGTL System as additional facilities were placed in service. Due to the flow-through treatment of certain expenses, including income taxes and depreciation on our Canadian rate-regulated pipelines, the accelerated tax depreciation changes in 2019 and increased depreciation expense impacts our comparable EBITDA despite having no significant effect on net income

• foreign exchange impact of a stronger U.S. dollar on the Canadian dollar equivalent earnings from our U.S. operations.

Comparable earnings in 2019 increased by $371 million or $0.28 per common share to $3.9 billion or $4.14 per common share compared to 2018 primarily due to the net effect of:

• changes in comparable EBITDA described above

• higher income tax expense due to increased comparable earnings before income taxes and lower foreign tax rate differentials, partially offset by lower flow-through income taxes on the Canadian Mainline reflecting the impact of the NEB 2018 Decision and on the NGTL System from the effect of accelerated tax depreciation

• higher depreciation largely in U.S. Natural Gas Pipelines reflecting new projects placed in service. Canadian Natural Gas Pipelines' depreciation also increased, however it is fully recovered in tolls on a flow-through basis as discussed in comparable EBITDA above, and therefore it has no significant impact on comparable earnings

• increased interest expense primarily as a result of long-term debt issuances, net of maturities, the foreign exchange impact on translation of U.S. dollar-denominated interest and higher levels of short-term borrowings, partially offset by higher capitalized interest

• lower AFUDC primarily due to Columbia Gas and Columbia Gulf growth projects placed in service, partially offset by capital expenditures on our NGTL System and continued investment in our Mexico projects.

Comparable earnings per share in 2019 and 2018 were impacted by the dilutive impact of common shares issued under our Corporate ATM program in 2018 and under our DRP.

Notable recent developments include:

Canadian Natural Gas Pipelines:

• Coastal GasLink Pipeline Project: We are proceeding with construction of the estimated $6.6 billion Coastal GasLink natural gas pipeline project. Coastal GasLink will be a 670 km (416 miles) pipeline with an initial capacity of approximately 2.2 PJ/d (2.1 Bcf/d) with potential expansion capacity up to 5.4 PJ/d (5.0 Bcf/d). All necessary regulatory permits for the initial capacity have been received and the project is expected to enter service in 2023. Coastal GasLink has signed project and community agreements with all 20 elected Indigenous bands along the pipeline route, confirming strong support from Indigenous communities across the province.

In December 2019, we entered into an agreement to sell a 65 per cent equity interest in Coastal GasLink to KKR-Keats Pipeline Investors II (Canada) Ltd. (KKR) and a subsidiary of Alberta Investment Management Corporation (AIMCo). Concurrent with the sale, TC Energy expects that Coastal GasLink will finalize a secured construction credit facility with a syndicate of banks to fund up to 80 per cent of the project's capital expenditures during construction. Both transactions are expected to close in the first half of 2020 subject to customary regulatory approvals and consents, including the consent of LNG Canada. As part of the transaction, we will be contracted by the Coastal GasLink Limited Partnership to construct and operate the pipeline.

Under the terms of the sale, we will receive upfront proceeds that include reimbursement of a 65 per cent proportionate share of the project costs incurred as of the closing as well as additional payment streams through construction and operation of the pipeline. We expect to record an after-tax gain of approximately $600 million upon closing of the transaction which includes the gain on sale, required revaluation of our 35 per cent residual ownership to fair market value and recognition of previously unrecorded tax benefits. Upon closing, we expect to account for our remaining 35 per cent investment using equity accounting.

The introduction of partners, establishment of a dedicated project-level financing facility, recovery of cash payments through construction for carrying charges on costs incurred and remuneration for costs to date are expected to substantially satisfy our funding requirements through project completion.

We are also committed to working with the 20 First Nations that have executed agreements with Coastal GasLink to provide them an opportunity to invest in the project. As a result, in conjunction with this sale, we will provide an option to the 20 First Nations to acquire a 10 per cent equity interest in Coastal GasLink on similar terms to what has been agreed with KKR and AIMCo.

• NGTL System: On February 12, 2020, we approved the 2023 NGTL Intra-Basin System Expansion for contracted incremental intra-basin firm delivery capacity of 331 TJ/d (309 MMcf/d) for 15-year terms. The expansion includes three segments of pipeline totaling 119 km (74 miles), 90 MW of additional compression and has an estimated capital cost of $0.9 billion with in-service dates commencing in 2023.

In October 2019, we announced our West Path Expansion Program, an expansion of our NGTL System and Foothills pipeline system for contracted incremental export capacity onto the Gas Transmission Northwest (GTN) system in the Pacific Northwest. The Canadian portion of the expansion program has an estimated capital cost of $1.0 billion and consists of approximately 103 km (64 miles) of pipeline and associated facilities with in-service dates in fourth quarter 2022 and fourth quarter 2023. This total program is underpinned by approximately 275 TJ/d (258 MMcf/d) of new firm service contracts with terms that exceed 30 years.

During 2019, the NGTL System placed approximately $1.3 billion of capacity projects in service.

On January 31, 2020, the $1.1 billion Aitken Creek section of the North Montney project was also placed in service, supplementing $0.3 billion of facilities completed in 2019. The balance of the $1.6 billion project is expected to be in service in second quarter 2020. The total project will add approximately 206 km (128 miles) of new pipeline along with three compressor units and 14 meter stations.

In March 2019, the NGTL System Rate Design and Services Application was filed with the National Energy Board (NEB), now the CER, which included a contested settlement agreement negotiated with its Tolls, Tariff, Facilities and Procedures (TTFP) committee. The settlement is supported by the majority of the TTFP committee members. The application addresses rate design, terms and conditions of service for the NGTL System and a tolling methodology for the North Montney Mainline (NMML). Given the complexity of the issues raised in the application, the CER held a public hearing in fourth quarter 2019. We anticipate a decision in first quarter 2020.

The NGTL System's 2018-2019 Revenue Requirement Settlement expired on December 31, 2019. We continue to work with NGTL stakeholders towards a new revenue requirement arrangement for 2020 and subsequent years. While these discussions continue, the NGTL System is operating under interim tolls for 2020 that were approved by the CER on December 6, 2019.

• Canadian Mainline: In December 2019, TC Energy filed an application on the Canadian Mainline tolls with the CER for approval of a six-year unanimous negotiated settlement with its customers and other interested parties encompassing a term from January 2021 through December 2026. The settlement sets a base equity return of 10.1 per cent on 40 per cent deemed common equity and includes an incentive to either decrease costs and/or increase revenues on the pipeline with a beneficial sharing mechanism to both the shippers and us.

U.S. Natural Gas Pipelines:

• Alberta XPress:On February 12, 2020, we approved the Alberta XPress project, an expansion project on the ANR Pipeline system that utilizes existing capacity on the Great Lakes and Canadian Mainline systems to connect growing supply from the Western Canadian Sedimentary Basin (WCSB) to U.S. Gulf Coast LNG export markets. The anticipated in-service date is in 2022 with estimated project costs of US$0.3 billion.

• Buckeye XPress: The Buckeye XPress project represents an upsizing of an existing pipeline replacement project in conjunction with our Columbia Gas modernization program. The US$0.2 billion cost to upsize the replacement pipe and install compressor upgrades will enable us to offer 290 TJ/d (275 MMcf/d) of incremental pipeline capacity to accommodate growing Appalachian production. The FERC certificate for Buckeye XPress was received in January 2020 and we expect the project to be placed in service in late 2020.

• GTN XPress:In October 2019, TC PipeLines, LP approved the GTN XPress project which is an integrated reliability and expansion project on the GTN system that will provide for the transport of additional volumes enabled by the NGTL System's West Path Delivery Program discussed previously. GTN XPress is expected to be complete in late 2023 with an estimated total cost of US$0.3 billion.

• Columbia Gulf Rate Settlement:In December 2019, FERC approved the uncontested Columbia Gulf rate settlement which set new recourse rates for Columbia Gulf effective August 1, 2020 and instituted a rate moratorium through August 1, 2022. The revised rates are not expected to have a significant impact on our U.S. Natural Gas Pipelines segment comparable earnings.

Mexico Natural Gas Pipelines:

• Villa de Reyes: Construction for the Villa de Reyes project is ongoing with a phased in-service anticipated to commence in second quarter 2020 with full in-service by the end of 2020. We have received capacity payments under force majeure provisions up to May 2019 but have not commenced recording revenues.

• Tula: The East Section of the Tula pipeline is available for interruptible transportation services until regular service under the Comisión Federal Electricidad (CFE) contract commences. Construction of the central segment of the Tula project has been delayed due to a lack of progress by the Secretary of Energy, the governmental department responsible for Indigenous consultations.The west section of Tula is mechanically complete and anticipated to go into service as soon as gas becomes available. Project completion is expected approximately two years after the consultation process is successfully concluded. We have received capacity payments under force majeure provisions up to June 2019 but have not commenced recording revenues.

• CFE Arbitration: In June 2019, CFE filed requests for arbitration under the Villa de Reyes and Tula contracts. The arbitration processes, and their fixed capacity payments under force majeure, have been suspended while negotiations with respect to the transportation services agreements progress.

Liquids Pipelines:

• Keystone XL: The U.S. Department of State issued a Final SEIS for the project in December 2019. The Final SEIS supplements the 2014 Keystone XL SEIS and underpins the Bureau of Land Management and U.S. Army Corps of Engineers permits.

On February 7, 2020, we received approval from the U.S. Bureau of Land Management allowing for the construction of the Keystone XL pipeline across federally managed lands in Montana and land managed by the U.S. Army Corps of Engineers at the Missouri River.

In March 2019, the U.S. President issued a new Presidential Permit for the Keystone XL project which superseded the 2017 permit. This resulted in the dismissal of certain legal claims related to the 2017 permit and an injunction barring certain pre-construction activities and construction of the project. The lawsuits were expanded to include challenges to the 2019 Presidential Permit and are proceeding in federal district court in Montana.

We continue to actively manage legal and regulatory matters as the project advances.

Power and Storage:

• Bruce Power – Life Extension: Bruce Power’s Unit 6 Major Component Replacement (MCR) outage commenced on January 17, 2020 and is expected to be completed in late 2023. We expect to invest approximately $2.4 billion in Bruce Power's life extension programs through 2023 which includes the Unit 6 MCR and approximately $5.8 billion post-2023. Future MCR investments will be subject to discrete decisions for each unit with specified off-ramps available for Bruce Power and the Independent Electricity System Operator (IESO).

• Ontario Natural Gas-fired Power Plants: On July 30, 2019, we entered into an agreement to sell our Halton Hills and Napanee power plants as well as our 50 per cent interest in Portlands Energy Centre to a subsidiary of Ontario Power Generation Inc. for proceeds of approximately $2.87 billion, subject to timing of the close and related adjustments. The sale is expected to close by the end of first quarter 2020 subject to conditions which include regulatory approvals and Napanee reaching commercial operations as outlined in the agreement.

Corporate:

• Common Share Dividend: Our Board of Directors declared a quarterly dividend of $0.81 per common share for the quarter ending March 31, 2020 on TC Energy's outstanding common shares. The quarterly amount is equivalent to $3.24 per common share on an annualized basis and represents an increase of eight per cent. This is the twentieth consecutive year the Board has raised the dividend.

• Dividend Reinvestment and Share Purchase Plan: Under the DRP, eligible holders of common and preferred shares of TC Energy can reinvest their dividends and make optional cash payments to obtain additional TC Energy common shares. From July 1, 2016 to October 31, 2019, common shares were issued from treasury at a discount of two per cent to market prices over a specified period. The participation rate by common shareholders in the DRP in 2019 was approximately 34 per cent, resulting in $711 million reinvested in common equity under the program.

Commencing with the dividends declared October 31, 2019, common shares purchased under TC Energy’s DRP will no longer be satisfied with shares issued from treasury at a discount, but rather will be acquired on the open market at 100 per cent of the weighted average purchase price.

NON-GAAP MEASURES

This news release references the following non-GAAP measures:

• comparable EBITDA

• comparable EBIT

• comparable earnings

• comparable earnings per common share

• funds generated from operations

• comparable funds generated from operations.

These measures do not have any standardized meaning as prescribed by GAAP and therefore may not be comparable to similar measures presented by other entities.

Comparable measures

We calculate comparable measures by adjusting certain GAAP measures for specific items we believe are significant but not reflective of our underlying operations in the period. Except as otherwise described herein, these comparable measures are calculated on a consistent basis from period to period and are adjusted for specific items in each period, as applicable.

Our decision not to adjust for a specific item is subjective and made after careful consideration. Specific items may include:

• gains or losses on sales of assets or assets held for sale

• income tax refunds and adjustments to enacted tax rates

• certain fair value adjustments relating to risk management activities

• legal, contractual and bankruptcy settlements

• impairment of goodwill, investments and other assets

• acquisition and integration costs

• restructuring costs.

TC ENERGY [4

FOURTH QUARTER NEWS RELEASE 2019

We exclude the unrealized gains and losses from changes in the fair value of derivatives used to reduce our exposure to certain financial and commodity price risks. These derivatives generally provide effective economic hedges, but do not meet the criteria for hedge accounting. As a result, the changes in fair value are recorded in net income. As these amounts do not accurately reflect the gains and losses that will be realized at settlement, we do not consider them reflective of our underlying operations.

The following table identifies our non-GAAP measures against their most directly comparable GAAP measures.

Comparable measure	GAAP measure
comparable EBITDA	segmented earnings
comparable EBIT	segmented earnings
comparable earnings	net income attributable to common shares
comparable earnings per common share	net income per common share
comparable funds generated from operations	net cash provided by operations

Comparable EBITDA and comparable EBIT

Comparable EBITDA represents segmented earnings adjusted for certain specific items, excluding non-cash charges for depreciation and amortization. We use comparable EBITDA as a measure of our earnings from ongoing operations as it is a useful indicator of our performance and is also presented on a consolidated basis. Comparable EBIT represents segmented earnings adjusted for specific items. Comparable EBIT is an effective tool for evaluating trends in each segment. Refer to each business segment section for a reconciliation to segmented earnings.

Comparable earnings and comparable earnings per common share

Comparable earnings represents earnings or losses attributable to common shareholders on a consolidated basis, adjusted for specific items. Comparable earnings is comprised of segmented earnings, Interest expense, AFUDC, Interest income and other, Income tax expense, Non-controlling interests and Preferred share dividends, adjusted for specific items. Refer to the Consolidated results section for reconciliations to Net income attributable to common shares and Net income per common share.

Funds generated from operations and comparable funds generated from operations

Funds generated from operations reflects net cash provided by operations before changes in operating working capital. We believe it is a useful measure of our consolidated operating cash flow because it does not include fluctuations from working capital balances, which do not necessarily reflect underlying operations in the same period, and is used to provide a consistent measure of the cash generating performance of our assets. Comparable funds generated from operations is adjusted for the cash impact of specific items noted above. Refer to Cash provided by operating activities section for a reconciliation to Net cash provided by operations.

Net income attributable to common shares increasedby $16 million and decreased by $0.01 per common share for the three months endedDecember 31, 2019 compared to the same period in 2018. Net income per common share reflects the dilutive impact of common shares issued under our DRP in fourth quarter 2018 and throughout 2019.

Net income included unrealized gains and losses from changes in risk management activities which we excluded along with other specific items as noted below to arrive at comparable earnings.

Fourth quarter 2019 results included:

• a valuation allowance release of $195 million related to certain prior years' U.S. tax losses resulting from our reassessment of deferred tax assets that are more likely than not to be realized

• an incremental after-tax loss of $61 million related to the Ontario natural gas-fired power plant assets held for sale, resulting in a total accrued after-tax loss of $194 million at December 31, 2019. The total after-tax loss on this sale is expected to be $280 million. The unrecorded portion of this loss at December 31, 2019 primarily reflects the residual costs expected to be incurred until Napanee is placed in service, including capitalized interest as well as expected closing adjustments, and will be recorded on or before closing of this transaction. Closing is anticipated by the end of first quarter 2020

• an additional $19 million expense related to state income taxes on the sale of certain Columbia midstream assets.

FOURTH QUARTER NEWS RELEASE 2019

Fourth quarter 2018 results included:

• an after-tax net loss of $7 million related to our U.S. Northeast power marketing contracts

• a $143 million after-tax gain related to the sale of our interests in the Cartier Wind power facilities

• a $115 million deferred income tax recovery from an MLP regulatory liability write-off as a result of the 2018 FERC Actions

• a $52 million recovery of deferred income taxes as a result of finalizing the impact of U.S. Tax Reform

• a $27 million income tax recovery related to the sales of our U.S. Northeast power generation assets

FOURTH QUARTER NEWS RELEASE 2019

Comparable EBITDA –2019 versus 2018

Comparable EBITDA decreased by $138 million for the three months endedDecember 31, 2019compared to the same period in 2018 primarily due to the net effect of the following:

• lower contribution from Canadian Natural Gas Pipelines primarily reflecting lower flow-through income taxes and depreciation as well as lower incentive earnings in the Canadian Mainline due to recording the full-year impact of the NEB 2018 Decision in fourth quarter 2018

• lower contribution from Liquids Pipelines primarily due to decreased volumes on the Keystone Pipeline System, lower margins on liquids marketing activities and the impact of the sale of an 85 per cent equity interest in Northern Courier on July 17, 2019

• higher contribution from U.S. Natural Gas Pipelines mainly due to incremental earnings from Columbia Gas growth projects placed in service, partially offset by decreased earnings from the sale of certain Columbia midstream assets on August 1, 2019 and from Bison (wholly owned by TC PipeLines, LP) following a 2018 agreement with two customers to pay out their future contract revenues and terminate the contracts

• higher contribution from Power and Storage primarily due to increased Bruce Power results from a higher realized power price and higher volumes, partially offset by lower results from our Alberta cogeneration plants and the sale of the Coolidge generating station on May 21, 2019

• higher equity earnings from our investment in the Sur de Texas pipeline which was placed in service in September 2019, at which time we began recording equity income from operations. Prior to in-service, Sur de Texas equity income primarily reflected AFUDC, net of our proportionate share of interest expense on inter-affiliate loans from its partners. Our share of this interest expense is fully offset in Interest income and other.

Due to the flow-through treatment of certain expenses including income taxes and depreciation on our Canadian rate-regulated pipelines, the decrease in these expenses impacts our comparable EBITDA despite having no significant effect on net income.

Comparable earnings –2019 versus 2018

Comparable earnings increasedby $24 million for the three months endedDecember 31, 2019 compared to the same period in 2018 primarily due to the net effect of:

• changes in comparable EBITDA described above

• higher interest income and other as a result of lower realized losses in 2019 compared to 2018 on derivatives used to manage our net exposure to foreign exchange rate fluctuations on U.S. dollar-denominated income

• lower income tax expense primarily due to lower flow-through income taxes in Canadian rate-regulated pipelines and lower comparable earnings before income taxes, partially offset by lower foreign tax rate differentials

• lower depreciation largely in Canadian Natural Gas Pipelines which is fully recovered in tolls as reflected in comparable EBITDA above, therefore having no significant impact on comparable earnings. This was partially offset by increased depreciation in U.S. Natural Gas Pipelines reflecting new projects placed in service

• lower AFUDC primarily due to Columbia Gas and Columbia Gulf growth projects placed in service, partially offset by capital expenditures on our NGTL System and continued investment in our Mexico projects.

Comparable earnings per common share for the three months endedDecember 31, 2019 was consistent with 2018 at $1.03 and reflects the dilutive impact of common shares issued under our DRP in fourth quarter 2018 and throughout 2019.

FOURTH QUARTER NEWS RELEASE 2019

Capital Program

We are developing quality projects under our capital program. These long-life infrastructure assets are supported by long-term commercial arrangements with creditworthy counterparties and/or regulated business models and are expected to generate significant growth in earnings and cash flows.

Our capital program consists of approximately $30 billion of secured projects which include commercially-supported, committed projects that are either under construction or are in or preparing to commence the permitting stage. An additional $21 billion of projects under development are commercially supported (except where noted) but have greater uncertainty with respect to timing and estimated project costs and remain subject to certain key approvals.

Three years of maintenance capital expenditures for our businesses are included in secured projects. Maintenance capital expenditures on our regulated Canadian and U.S. natural gas pipelines businesses are added to rate base on which we have the opportunity to earn a return and recover these expenditures through current or future tolls, which is similar to our capacity capital projects on these pipelines. Tolling arrangements in our liquids pipelines business provide for the recovery of maintenance capital expenditures.

In 2019, we placed approximately $8.7 billion of capacity projects in service including Mountaineer XPress, Gulf XPress, various NGTL System expansions and the Sur de Texas and White Spruce pipelines. In addition, approximately $2 billion of maintenance capital expenditures were incurred.

All projects are subject to cost and timing adjustments due to weather, market conditions, route refinement, permitting conditions, scheduling and timing of regulatory permits, among other factors. Amounts presented in the following tables exclude capitalized interest and AFUDC.

1 Includes results from Foothills, Ventures LP, Great Lakes Canada and our share of equity income from our investment in TQM, as well as general and administrative and business development costs related to our Canadian Natural Gas Pipelines.

Canadian Natural Gas Pipelines comparable EBIT and segmented earnings decreased by $129 million for the three months endedDecember 31, 2019 compared to the same period in 2018.

Net income and comparable EBITDA for our rate-regulated Canadian natural gas pipelines are primarily affected by our approved ROE, our investment base, the level of deemed common equity and incentive earnings. Changes in depreciation, financial charges and income taxes also impact comparable EBITDA but do not have a significant impact on net income as they are almost entirely recovered in revenue on a flow-through basis.

Net income for the NGTL System increased by $20 million for the three months endedDecember 31, 2019 compared to the same period in 2018 mainly due to a higher average investment base resulting from continued system expansions.

Net income for the Canadian Mainline decreased by $17 million for the three months endedDecember 31, 2019 compared to the same period in 2018 mainly due to lower net incentive earnings, partially offset by lower carrying charges on the 2019 revenue surplus. In December 2018, the NEB 2018 Decision was received and, as such, net incentive earnings for the full year of 2018 were recorded in fourth quarter 2018. The NEB 2018 Decision also included an accelerated amortization of the December 31, 2017 LTAA balance and an increase to the composite depreciation rate from 3.2 per cent to 3.9 per cent.

COMPARABLE EBITDA

Comparable EBITDA for Canadian Natural Gas Pipelines decreased by $200 million for the three months endedDecember 31, 2019 compared to the same period in 2018 due to the net effect of:

• lower depreciation, income taxes and incentive earnings on the Canadian Mainline resulting from recording the full-year impact of the NEB 2018 Decision in fourth quarter 2018 which increased earnings in that quarter

• increased rate base earnings and depreciation on the NGTL System due to additional facilities that were placed in service.

Due to the flow-through treatment of income taxes and depreciation on our Canadian rate-regulated pipelines, changes in these items impact comparable EBITDA despite having no significant impact on net income.

DEPRECIATION AND AMORTIZATION

Depreciation and amortization decreased by $71 million for the three months endedDecember 31, 2019 compared to the same period in 2018 mainly due to recording the full-year impact of higher depreciation rates approved in the Canadian Mainline NEB 2018 Decision in December 2018, partially offset by the additional NGTL System facilities that were placed in service.

FOURTH QUARTER NEWS RELEASE 2019

U.S. Natural Gas Pipelines segmented earnings increased by $700 million for the three months endedDecember 31, 2019 compared to the same period in 2018 mainly due to the following specific items recorded in 2018 which are excluded from our calculation of comparable EBIT and comparable earnings:

• a $722 million pre-tax non-cash asset impairment charge related to Bison

• a $79 million pre-tax non-cash goodwill impairment charge related to Tuscarora

• $130 million of pre-tax customer termination payments that were recorded in Revenues with respect to two of Bison's transportation contracts.

Each of the specific items noted above are before reduction for the 74.5 per cent non-controlling interests in TC PipeLines, LP.

Comparable EBITDA for U.S. Natural Gas Pipelines increased by US$35 million for the three months endedDecember 31, 2019 compared to the same period in 2018 which was primarily the net effect of:

• incremental earnings from Columbia Gas growth projects placed in service

• decreased earnings as a result of the sale of certain Columbia midstream assets on August 1, 2019

• decreased earnings from Bison following the 2018 customer agreements to pay out their future contracted revenues and terminate their contracts.

DEPRECIATION AND AMORTIZATION

Depreciation and amortization increased by US$12 million for the three months endedDecember 31, 2019 compared to the same period in 2018 mainly due to new projects placed in service, partially offset by lower depreciation as a result of the Bison asset impairment in 2018 and the sale of certain Columbia midstream assets on August 1, 2019.

Mexico Natural Gas Pipelines comparable EBIT and segmented earnings increased by $8 million for the three months endedDecember 31, 2019 compared to the same period in 2018 principally due to increased EBITDA as described below.

Comparable EBITDA for Mexico Natural Gas Pipelines increasedby US$10 million for the three months endedDecember 31, 2019 compared to the same period in 2018 mainly due to the net effect of:

• higher equity earnings from our investment in the Sur de Texas pipeline which was placed in service in September 2019, at which time we began recording equity income from operations. Prior to in-service, Sur de Texas equity income reflected AFUDC, net of our proportionate share of interest expense on inter-affiliate loans. Our share of this interest expense is fully offset in Interest income and other

• lower revenues from other operations primarily as a result of changes in timing of revenue recognition in 2018.

DEPRECIATION AND AMORTIZATION

Depreciation and amortization increased by US$3 million for the three months endedDecember 31, 2019 compared to the same period in 2018 reflecting new assets being placed in service and other adjustments.

Comparable EBITDA for Liquids Pipelines decreasedby $66 million for the three months endedDecember 31, 2019 compared to the same period in 2018. This was primarily the net effect of:

• lower volumes on the Keystone Pipeline System

• lower contribution from liquids marketing activities due to lower margins

Power and Storage segmented earnings decreased by $213 million for the three months endedDecember 31, 2019 compared to the same period in 2018 and included the following specific items which have been excluded from comparable EBIT:

• an additional pre-tax loss in fourth quarter 2019 of $77 million related to the Ontario natural gas-fired power plant assets held for sale

• a pre-tax net loss in fourth quarter 2018 of $10 million related to U.S. Northeast power marketing contracts, the remainder of which were sold in May 2019

• a pre-tax gain in December 2018 of $170 million related to the sale of our interests in the Cartier Wind power facilities

• unrealized losses and gains from changes in the fair value of derivatives used to reduce our exposure to certain commodity price risks.

Comparable EBITDA for Power and Storage increased by $43 million for the three months endedDecember 31, 2019 compared to the same period in 2018 primarily due to the net effect of:

• increased Bruce Power results mainly due to a higher realized power price and higher volumes as a result of fewer outage days. Additional financial and operating information on Bruce Power is provided below

• a lower Canadian Power contribution largely as a result of the sale of the Coolidge generating station on May 21, 2019, a prior period billing adjustment as well as greater outage days at our Alberta cogeneration plants.

FOURTH QUARTER NEWS RELEASE 2019

DEPRECIATION AND AMORTIZATION

Depreciation and amortization increased by $2 million for the three months endedDecember 31, 2019 compared to the same period in 2018 as a result of higher depreciation at our Alberta cogeneration plants due to a reassessment of the useful life of certain components. This increase was offset by the cessation of depreciation on our Halton Hills power plant at July 30, 2019 and on the Coolidge generating station at December 31, 2018 upon their classifications as held for sale.

Corporate segmented earnings decreased by $92 million for the three months endedDecember 31, 2019 compared to the same period in 2018. Segmented (losses)/earnings within this period included foreign exchange losses of $64 million in 2019 compared to gains of $57 million in 2018 on our proportionate share of peso-denominated inter-affiliate loans to the Sur de Texas joint venture from its partners. These amounts are recorded in Income from equity investments and have been excluded from our calculation of comparable EBITDA and EBIT as they are fully offset by corresponding foreign exchange gains and losses included in Interest income and other on the inter-affiliate loan receivable for our proportionate share of the project's long-term financing requirements.

Comparable EBITDA increased by $29 million for the three months endedDecember 31, 2019 compared to the same period in 2018 primarily due to higher general and administrative costs in 2018.

Our proportionate share of the corresponding interest expense and foreign exchange in Sur de Texas are reflected in Income from equity investments in the Mexico Natural Gas Pipelines and Corporate segments, respectively, resulting in no impact on net income. The offsetting foreign exchange gain and loss amounts are excluded from comparable earnings

• unrealized gains on risk management activities in 2019 compared to unrealized losses in 2018 primarily reflecting the weakening and strengthening of the U.S. dollar at the end of 2019 and 2018, respectively. These amounts have been excluded from comparable earnings

Income tax expense included in comparable earnings decreased by $57 million for the three months endedDecember 31, 2019 compared to the same period in 2018. This was primarily due to lower flow-through income taxes in Canadian rate-regulated pipelines and lower comparable earnings before income taxes, partially offset by lower foreign tax rate differentials.

In addition to the tax impacts of the specific items noted in the U.S. Natural Gas Pipelines, Liquids Pipelines, Power and Storage and Corporate segments, Income tax expense in the three months endedDecember 31, 2019 and 2018 included the following specific items which have been excluded from our calculation of income tax expense included in comparable earnings:

• in fourth quarter 2019, a valuation allowance release of $195 million related to certain prior years' U.S. tax losses resulting from our reassessment of deferred tax assets that are more likely than not to be realized

• in fourth quarter 2019, an additional $19 million expense related to state income taxes on the sale of certain Columbia midstream assets

• in fourth quarter 2018, a $115 million deferred income tax recovery from an MLP regulatory write-off as a result of the 2018 FERC Actions
