Management’s discussion and analysis

April 30, 2026

This management’s discussion and analysis (MD&A) contains information to help the reader make investment decisions about TC Energy Corporation (TC Energy). It discusses our business, operations, financial position, risks and other factors for the three months ended March 31, 2026 and should be read with the accompanying unaudited Condensed consolidated financial statements for the three months ended March 31, 2026, which have been prepared in accordance with U.S. GAAP.

This MD&A should also be read in conjunction with our December 31, 2025 audited Consolidated financial statements and notes and the MD&A in our 2025 Annual Report. Capitalized and abbreviated terms that are used but not otherwise defined herein are defined in our 2025 Annual Report. Certain comparative figures have been adjusted to reflect the current period's presentation.

On October 1, 2024, TC Energy completed the spinoff of its Liquids Pipelines business into a new public company, South Bow Corporation (the Spinoff Transaction). Upon completion of the Spinoff Transaction, the Liquids Pipelines business was accounted for as a discontinued operation. For the three months ended March 31, 2026 and 2025, we did not recognize any income or loss from discontinued operations.

Financial highlights

We use certain financial measures that do not have a standardized meaning under GAAP because we believe they improve our ability to compare results between reporting periods and enhance understanding of our operating performance. Known as non-GAAP measures, they may not be comparable to similar measures provided by other companies.

Comparable EBITDA, comparable earnings, comparable earnings per common share and comparable funds generated from operations are all non-GAAP measures. Refer to the Non-GAAP measures section for additional information, as well as each business segment and the Financial condition sections for reconciliations to the most directly comparable GAAP measures.

NON-GAAP MEASURES

This MD&A references non-GAAP measures, which are identified in the table below. 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. These measures are reviewed regularly by our President and Chief Executive Officer, management and the Board of Directors in assessing our performance and making decisions regarding the ongoing operations of our business and its ability to generate cash flows. Some or all of these measures may also be used by investors and other external users of our financial statements as a supplemental measure to provide decision-useful information regarding our period-over-period performance and ability to generate earnings that are core to our ongoing operations. Discussions throughout this MD&A on the factors impacting comparable earnings before interest, taxes, depreciation and amortization (comparable EBITDA) and comparable earnings before interest and taxes (comparable EBIT) are consistent with the factors that impact segmented earnings, except where noted otherwise.

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 to adjust for a specific item in reporting comparable measures is subjective and made after careful consideration. We maintain a consistent approach to adjustments, which generally fall into the categories described below:

•by their nature are unusual, infrequent and separately identifiable from our normal business operations and in our view are not reflective of our underlying operations in the period and generally include the following:

◦gains or losses on sales of assets or assets held for sale; impairment of goodwill, plant, property and equipment, equity investments and other assets; legal, contractual and other infrequent settlements; acquisition, integration and restructuring costs; expected credit loss provisions on net investment in leases and certain contract assets in Mexico; impacts resulting from changes in legislation and enacted tax rates and unusual tax refunds/payments and valuation allowance adjustments

•unrealized gains and losses related to fair value adjustments that do not reflect realized earnings or losses or cash impacts incurred in the current period from our underlying operations and generally include the following:

◦unrealized gains and losses from changes in the fair value of derivatives related to financial and commodity price risk management activities; unrealized fair value adjustments related to our proportionate share of Bruce Power’s risk management activities and its funds invested for post-retirement benefits and unrealized foreign exchange gains and losses on intercompany loans that impact consolidated earnings.

The following table identifies our non-GAAP measures against their most directly comparable GAAP measures. Quantitative reconciliations of our comparable measures to their GAAP measures and a discussion of specific adjustments made for the three months ended March 31, 2026 and comparative period are found throughout this MD&A.

Non-GAAP measure	GAAP measure
comparable EBITDA	segmented earnings (losses)
comparable EBIT	segmented earnings (losses)
comparable earnings	net income (loss) attributable to common shares
comparable earnings per common share	net income (loss) per common share
funds generated from operations	net cash provided by operations

Comparable EBITDA and comparable EBIT

Comparable EBITDA represents segmented earnings (losses) adjusted for specific items described in the Comparable measures section, excluding 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 (losses) adjusted for specific items and is an effective tool for evaluating trends in each segment. Refer to each business segment for a reconciliation to segmented earnings (losses).

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. The components of changes in working capital are disclosed in the Consolidated financial statements of our 2025 Annual Report. Comparable funds generated from operations is adjusted for the cash impact of specific items described in the Comparable measures section. We believe funds generated from operations and comparable funds generated from operations are useful measures of our consolidated operating cash flows because they exclude fluctuations from working capital balances, which do not necessarily reflect underlying operations in the same period, and are used to provide a consistent measure of the cash-generating ability of our businesses. Refer to the Financial condition section for a reconciliation to Net cash provided by operations.

Comparable earnings and comparable earnings per common share

Comparable earnings represents earnings attributable to common shareholders on a consolidated basis, adjusted for specific items described in the Comparable measures section. Comparable earnings is comprised of segmented earnings (losses), Interest expense, AFUDC, Foreign exchange (gains) losses, net, Interest income and other, Income tax expense (recovery), Net income (loss) attributable to non-controlling interests and Preferred share dividends in our Condensed consolidated statement of income, adjusted for specific items. We use comparable earnings 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. Refer to the following page for reconciliations to Net income (loss) attributable to common shares and Net income (loss) per common share.

Comparable earnings and comparable earnings per common share

The following specific items were recognized in Net income (loss) attributable to common shares and were excluded from comparable earnings:

2026 results

•pre-tax unrealized foreign exchange gains, net, of $58 million on the peso-denominated intercompany loan between TransCanada PipeLines Limited (TCPL) and Transportadora de Gas Natural de la Huasteca (TGNH), net of non-controlling interest

•a pre-tax expense of $33 million related to the resolution of certain legal matters within our U.S. Natural Gas Pipelines segment

•a pre-tax expense of $17 million on the expected credit loss provision related to TGNH net investment in leases, net of non-controlling interest as well as on certain contract assets in Mexico.

2025 results

•pre-tax unrealized foreign exchange gains, net, of $3 million on the peso-denominated intercompany loan between TCPL and TGNH, net of non-controlling interest

•a pre-tax recovery of $2 million on the expected credit loss provision related to TGNH net investment in leases, net of non-controlling interest as well as on certain contract assets in Mexico.

1TCPL and TGNH are parties to an unsecured revolving credit facility. While the loan receivable and payable eliminate on consolidation, differences in each entity’s reporting currency create a net income impact from revaluing and translating these balances into TC Energy’s reporting currency. As the resulting unrealized foreign exchange gains and losses do not reflect amounts expected to be realized at settlement, we exclude them from comparable measures, net of non‑controlling interest.

2We have recognized an expected credit loss provision related to net investment in leases and certain contract assets in Mexico, which will fluctuate from period to period based on changing economic assumptions and forward-looking information. This provision is an estimate of losses that may occur over the duration of the TSA through 2055. This provision does not reflect losses or cash outflows that were incurred under this lease arrangement in the current period or from our underlying operations, and therefore, we have excluded any unrealized changes, net of non-controlling interest, from comparable measures.

Comparable EBITDA – 2026 versus 2025

Comparable EBITDA increased by $379 million for the three months ended March 31, 2026 compared to the same period in 2025 primarily due to the net result of the following:

•increased U.S. dollar-denominated EBITDA in Mexico Natural Gas Pipelines due to higher earnings in TGNH primarily related to the completion of the Southeast Gateway pipeline in second quarter 2025 and higher equity earnings from Sur de Texas as a result of peso-denominated financial exposure

•increased U.S. dollar-denominated EBITDA in U.S. Natural Gas Pipelines due to an increase in earnings from Columbia Gas as a result of higher transportation rates effective April 1, 2025, settlement-in-principle reached with ANR and additional contract sales, partially offset by lower margins in our U.S. natural gas marketing business

•increased EBITDA in Canadian Natural Gas Pipelines mainly due to higher flow-through depreciation on both the NGTL System and Canadian Mainline and incentive earnings on the NGTL System, partially offset by lower flow-through income taxes on the Canadian Mainline

•increased EBITDA in Power and Energy Solutions mainly attributable to higher net contributions from Bruce Power due to a higher contract price partially offset by reduced generation primarily resulting from the Unit 4 Major Component Replacement (MCR)

•a negative foreign exchange impact of a weaker U.S. dollar on the Canadian dollar equivalent comparable EBITDA in our U.S. dollar-denominated operations, which was translated at a rate of 1.37 in 2026 versus 1.43 in 2025. Refer to the Foreign exchange section for additional information.

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

TC Energy First Quarter 2026 | 9

Comparable earnings – 2026 versus 2025

Comparable earnings increased by $48 million or 0.04 per common share for the three months ended March 31, 2026 compared to the same period in 2025 primarily due to the net effect of the following:

•changes in comparable EBITDA described above

•lower AFUDC primarily due to the completion of the Southeast Gateway pipeline

•higher net income attributable to non-controlling interests primarily from higher net income recognized from the Columbia Gas and Columbia Gulf assets

•higher depreciation and amortization primarily due to assets placed in service in our Canadian Natural Gas Pipeline segment, higher depreciation rates on the NGTL System and depreciation rate changes as a result of the Columbia Gas Settlement and ANR settlement-in-principle

•higher income tax expense primarily due to a change in geographic and business mix of earnings and higher flow-through income taxes partially offset by the impact of Mexico foreign exchange exposure

•lower interest income and other due to the change in fair value of other restricted investments

•risk management activities used to manage our foreign exchange exposure.

Supplementary financial measure

Net capital expenditures

Net capital expenditures represents capital costs incurred for growth projects, maintenance capital expenditures, contributions to equity investments and projects under development, adjusted for the portion attributed to non-controlling interests in the entities we control. Net capital expenditures reflect capital costs incurred during the period, excluding the impact of timing of cash payments. We use net capital expenditures as a key measure in evaluating our performance in managing our capital spending activities in comparison to our capital plan.

Net capital expenditures does not include an adjustment related to the CFE’s minority interest in TGNH capital expenditures until after the in-service of the projects included as part of the 2022 strategic alliance between TGNH and the CFE. The CFE’s contribution in second quarter 2024 to obtain a 13.01 per cent equity interest in TGNH included consideration of its proportionate share of required capital contributions for approved projects. Net capital expenditures will be adjusted for any new capital projects approved in TGNH going forward.

Outlook

Comparable EBITDA and comparable earnings

Our overall comparable EBITDA and comparable earnings per common share outlooks for 2026 remain consistent with our 2025 Annual Report.

Consolidated capital expenditures

Our expected total capital expenditures for 2026 as outlined in our 2025 Annual Report remain materially unchanged.

TC Energy First Quarter 2026 | 11

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 growth in earnings and cash flows.

Our capital program consists of approximately $23 billion of secured projects that represent commercially supported, committed projects that are either under construction or are in, or preparing to commence the permitting stage.

Three years of maintenance capital expenditures for our businesses are included in the Secured projects table. Maintenance capital expenditures on our regulated Canadian and U.S. natural gas pipelines 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.

For the three months ended March 31, 2026, we placed approximately $0.4 billion of natural gas pipeline capacity projects into service along our extensive North American asset footprint. In addition, approximately $0.3 billion of maintenance capital expenditures were incurred in the period.

All projects are subject to cost and timing adjustments due to factors including weather, market conditions, route refinement, land acquisition, permitting conditions, scheduling and timing of regulatory permits, as well as other potential restrictions and uncertainties, including inflationary pressures on labour and materials. Amounts exclude capitalized interest and AFUDC, where applicable.

In addition to our secured projects, we are pursuing a portfolio of quality projects in various stages of development across each of our business units as discussed in our 2025 Annual Report. Projects under development have greater uncertainty with respect to timing and estimated project costs and are subject to corporate and regulatory approvals, unless otherwise noted. While each business segment also has additional areas of focus for further ongoing business development activities and growth opportunities, new opportunities will be assessed within our capital allocation framework in order to fit within our annual capital expenditure parameters. As these projects advance and reach necessary milestones they will be included in the Secured projects table on the following page. Refer to the Recent developments section for updates to our secured projects and projects under development.

Canadian Natural Gas Pipelines segmented earnings decreased by $7 million for the three months ended March 31, 2026 compared to the same period in 2025.

Net income for our rate-regulated Canadian natural gas pipelines is primarily affected by our approved ROE, investment base, the level of deemed common equity and incentive earnings. Comparable EBITDA is impacted by these factors, as well as changes in depreciation, financial charges and income taxes. These additional items do not have a significant impact on net income as they are almost entirely recovered in revenues on a flow-through basis.

All values are in US Dollars.

Net income for the NGTL System increased by $6 million for the three months ended March 31, 2026 compared to the same period in 2025 primarily due to higher incentive earnings. The NGTL System is currently operating under the 2025-2029 NGTL Settlement, which includes an approved ROE of 10.1 per cent on 40 per cent deemed common equity. This settlement provides the NGTL System with higher depreciation rates and the opportunity to further increase depreciation rates with an incentive if tolls fall below specified levels, or if growth projects are undertaken. It also includes incentive mechanisms to reduce both physical emissions and emission compliance costs, while also providing incentive for certain operating costs where variances from projected amounts and emissions savings are shared with customers.

Net income for the Canadian Mainline was consistent for the three months ended March 31, 2026 compared to the same period in 2025. The Canadian Mainline is operating under the 2021-2026 Mainline Settlement, which includes an approved ROE of 10.1 per cent on 40 per cent deemed common equity and an incentive to decrease costs and increase revenues on the pipeline under a beneficial sharing mechanism with our customers.

COMPARABLE EBITDA

Comparable EBITDA for Canadian Natural Gas Pipelines increased by $29 million for the three months ended March 31, 2026 compared to the same period in 2025 due to the net effect of higher flow-through depreciation and incentive earnings on the NGTL System along with higher flow-through depreciation, partially offset by lower flow-through income taxes on the Canadian Mainline.

DEPRECIATION AND AMORTIZATION

Depreciation and amortization increased by $36 million for the three months ended March 31, 2026 compared to the same period in 2025 mainly due to an increase in assets placed in service on the Canadian Mainline and higher depreciation rates and expansion facilities placed in service on the NGTL System.

U.S. Natural Gas Pipelines segmented earnings decreased by $34 million for the three months ended March 31, 2026 compared to the same period in 2025 and included the following specific items which have been excluded from our calculation of comparable EBITDA and comparable EBIT:

•a pre-tax expense of $33 million related to the resolution of certain legal matters within our U.S. Natural Gas Pipelines segment

•unrealized gains and losses from changes in the fair value of derivatives used in our U.S. natural gas marketing business.

A weaker U.S. dollar for the three months ended March 31, 2026 had a negative impact on the Canadian dollar equivalent segmented earnings from our U.S. dollar-denominated operations compared to the same period in 2025. Refer to the Foreign exchange section for additional information.

Earnings from our U.S. Natural Gas Pipelines operations are generally affected by contracted volume levels, volumes delivered and the rates charged, as well as by the cost of providing services. Columbia Gas and ANR results are also affected by the contracting and pricing of their natural gas storage capacity and incidental commodity sales. Natural gas pipeline and storage volumes and revenues are generally higher in the winter months because of the seasonal nature of the business.

16 | TC Energy First Quarter 2026

Comparable EBITDA for U.S. Natural Gas Pipelines increased by US$138 million for the three months ended March 31, 2026 compared to the same period in 2025 and was primarily due to the net effect of:

•a net increase in earnings from Columbia Gas as a result of higher transportation rates effective April 1, 2025, pursuant to the Columbia Gas Settlement

•a net increase in earnings from ANR as a result of higher transportation rates effective November 1, 2025 as well as adjustments related to the ANR settlement-in-principle

•incremental earnings from projects placed in service and lower operating costs on Columbia Gulf

•increased earnings from additional short-term contract sales due to the impacts of a cold weather event across multiple U.S. Natural Gas Pipeline assets

•lower realized earnings related to our U.S. natural gas marketing business primarily due to reduced trading margins from the impacts of a cold weather event.

DEPRECIATION AND AMORTIZATION

Depreciation and amortization increased by US$11 million for the three months ended March 31, 2026 compared to the same period in 2025 primarily due to new projects placed in service and depreciation rate changes as a result of the Columbia Gas Settlement, offset by a decrease in depreciation rate changes as a result of the ANR settlement-in-principle.

Mexico Natural Gas Pipelines segmented earnings increased by $178 million for the three months ended March 31, 2026 compared to the same period in 2025 and included an expense of $19 million (2025 – recovery of $2 million) on the expected credit loss provision related to the TGNH net investment in leases and certain contract assets in Mexico, which has been excluded from our calculation of comparable EBITDA and comparable EBIT.

A weaker U.S. dollar for the three months ended March 31, 2026 had a negative impact on the Canadian dollar equivalent segmented earnings from our U.S. dollar-denominated operations in Mexico compared to the same period in 2025. Refer to the Foreign exchange section for additional information.

Comparable EBITDA for Mexico Natural Gas Pipelines increased by US$152 million for the three months ended March 31, 2026 compared with the same period in 2025 due to:

•higher earnings in TGNH due to the completion of the Southeast Gateway pipeline in second quarter 2025

•higher equity earnings from Sur de Texas primarily due to the foreign exchange impacts on the revaluation of peso-denominated liabilities as well as lower interest expense.

DEPRECIATION AND AMORTIZATION

Depreciation and amortization was generally consistent for the three months ended March 31, 2026 compared to the same period in 2025. Under sales-type lease accounting, our in-service TGNH pipeline assets are derecognized from Plant, property and equipment and recorded as a net investment in lease on our Condensed consolidated balance sheet with no depreciation expense being recognized.

Foreign exchange

FOREIGN EXCHANGE RELATED TO U.S. DOLLAR-DENOMINATED OPERATIONS

Certain of our businesses generate all or most of their earnings in U.S. dollars and since we report our financial results in Canadian dollars, changes in the value of the U.S. dollar against the Canadian dollar directly affect our comparable EBITDA and may also impact comparable earnings. As our U.S. dollar-denominated operations continue to grow, this exposure increases. A portion of the U.S. dollar-denominated comparable EBITDA exposure is naturally offset by U.S. dollar-denominated amounts below comparable EBITDA within Depreciation and amortization, Interest expense and other income statement line items. A portion of the remaining exposure is actively managed on a rolling forward basis up to three years using foreign exchange derivatives; however, the natural exposure beyond that period remains. The net impact of the U.S. dollar movements on comparable earnings during the three months ended March 31, 2026 after considering natural offsets and economic hedges was not significant.

The components of our financial results denominated in U.S. dollars are set out in the table below, including our U.S. Natural Gas Pipelines and Mexico Natural Gas Pipelines operations. Comparable EBITDA is a non-GAAP measure.

All values are in US Dollars.

FOREIGN EXCHANGE RELATED TO MEXICO NATURAL GAS PIPELINES

Changes in the value of the Mexican peso against the U.S. dollar can affect our comparable earnings as a portion of our Mexico Natural Gas Pipelines' monetary assets and liabilities are peso-denominated, while our financial results are denominated in U.S. dollars for our Mexico operations. These peso-denominated balances are revalued to U.S. dollars, creating foreign exchange gains and losses that are included in Income (loss) from equity investments, Foreign exchange (gains) losses, net and Net income (loss) attributable to non-controlling interests in the Condensed consolidated statement of income.

In addition, foreign exchange gains or losses calculated for Mexico income tax purposes on the revaluation of U.S. dollar‑denominated monetary assets and liabilities result in a peso-denominated income tax exposure for these entities, leading to fluctuations in Income from equity investments and Income tax expense. This exposure increases as our U.S. dollar‑denominated net monetary liabilities grow.

The above exposures are managed using foreign exchange derivatives, although some unhedged exposure remains. The impacts of the foreign exchange derivatives are recorded in Foreign exchange (gains) losses, net in the Condensed consolidated statement of income. Refer to the Financial risks and financial instruments section for additional information.

Recent developments

CANADIAN NATURAL GAS PIPELINES

NGTL System

In the three months ended March 31, 2026, the NGTL System placed approximately $0.4 billion of capacity projects into service, including $0.1 billion of Multi-Year Growth Plan (MYGP) projects.

Multi-Year Growth Plan

The 2025-2029 NGTL Settlement enables an investment framework that supports our Board of Directors' approval to allocate up to $3.3 billion of capital towards progression of the MYGP for expansion facilities to meet commitments on the NGTL System. It is comprised of multiple distinct projects with various targeted in-service dates, subject to final company and regulatory approvals. As of March 31, 2026, approximately $1.1 billion of expansion facilities have received FID, with various in-service dates starting in 2026. As we have continued to evaluate plans for each MYGP facility, we do not expect that all facilities up to the Board-approved capital allocation will be required to satisfy our MYGP capacity commitments of approximately 1.0 Bcf/d of incremental system throughput.

Valhalla North and Berland River Project

The Valhalla North and Berland River project continues to advance. The Valhalla section, which consists of approximately 33 km (21 miles) of new pipeline, was placed in service in third quarter 2025, with a capital cost of approximately $0.2 billion. The construction of the Berland River non‑emitting electric compressor unit was completed in first quarter 2026, with a capital cost of approximately $0.3 billion, and is expected to be operational in the second half of 2026 upon completion of the third-party power transmission connection. The project is designed to provide incremental capacity on the NGTL System of approximately 428 TJ/d (400 MMcf/d).

Canadian Mainline Settlement

In March 2026, we filed an application with the CER seeking approval of a four‑year negotiated settlement governing the Canadian Mainline tolls and service for the period from January 2027 through December 2030. The proposed settlement, supported by our customers and other interested parties, maintains a return on equity of 10.1 per cent on 40 per cent deemed common equity and includes an incentive mechanism designed to encourage cost management and revenue optimization, with benefits shared between customers and us. This incentive provides the opportunity to outperform the approved rate of return. In addition, TC Energy has committed up to $200 million of capital to support incremental capacity, with targeted returns that exceed the approved return on equity.

Coastal GasLink

Coastal GasLink Pipeline Phase 2 Expansion

In March 2026, Coastal GasLink Limited Partnership (Coastal GasLink LP) entered into commercial agreements with LNG Canada (LNGC), which establish a framework for advancing a proposed expansion of the Coastal GasLink pipeline (the CGL Phase 2 Expansion) to enable the delivery of incremental pipeline capacity to the LNGC export facility in Kitimat, British Columbia. The commercial structure of the agreements includes limits on Coastal GasLink LP's capital commitments and overall liability for construction cost and schedule risks. Under the agreements, LNGC will lead project construction as the CGL Phase 2 Expansion execution manager and Coastal GasLink LP will provide LNGC technical advisory services. The CGL Phase 2 Expansion remains subject to FID by LNGC and its joint venture participants, as well as approval by Coastal GasLink LP.

Financial condition

We strive to maintain financial strength and flexibility in all parts of the economic cycle. We rely on our operating cash flows to sustain our business, pay dividends and fund a portion of our growth. In addition, we access capital markets and engage in portfolio management activities to meet our financing needs and to manage our capital structure and credit ratings.

We believe that we have the financial capacity to fund our existing capital program through predictable cash flows from operations, access to capital markets, portfolio management activities, joint ventures, asset-level financing, cash on hand and substantial committed credit facilities. Annually, in the fourth quarter, we renew and extend our credit facilities as required.

At March 31, 2026, our current assets totaled $6.8 billion and current liabilities amounted to $10.3 billion, leaving us with a working capital deficit of $3.5 billion compared to a deficit of $3.7 billion at December 31, 2025, excluding discontinued operations. Our working capital deficiency is considered to be in the normal course of business and is managed through:

•our ability to generate predictable cash flows from operations

•a total of $7.9 billion of TCPL committed revolving credit facilities, of which $6.8 billion of short-term borrowing capacity remains available, net of $1.1 billion backstopping outstanding commercial paper balances, and arrangements for a further $2.0 billion of demand credit facilities, of which $1.2 billion remains available as of March 31, 2026

•additional $2.1 billion of committed revolving credit facilities at certain of our subsidiaries and affiliates, of which $0.9 billion of short-term borrowing capacity remains available as of March 31, 2026, net of $1.2 billion backstopping outstanding commercial paper balances

•our access to capital markets, including through securities issuances, incremental credit facilities, capital rotation and DRP, if deemed appropriate.

Net cash provided by operations

Net cash provided by operations increased by $1,244 million for the three months ended March 31, 2026 compared to the same period in 2025 primarily due to the timing of working capital changes and higher funds generated from operations.

Comparable funds generated from operations

Comparable funds generated from operations, a non-GAAP measure, helps us assess the cash generating ability of our businesses by excluding the timing effects of working capital changes, as well as the cash impact of our specific items.

Comparable funds generated from operations increased by $387 million for the three months ended March 31, 2026 compared to the same period in 2025 primarily due to higher comparable earnings and higher distributions from our equity investments.

DIVIDENDS

Our Board of Directors have declared a quarterly dividend on our outstanding common shares of $0.8775 per common share for the quarter ending June 30, 2026.

SHARE INFORMATION

At April 24, 2026, we had approximately 1.0 billion issued and outstanding common shares and approximately 1.4 million outstanding and exercisable options to buy common shares.

On January 30, 2026, the remaining 1,929,407 Series 6 preferred shares were converted, on a one-for-one basis, into 1,929,407 Series 5 preferred shares and Series 6 preferred shares were delisted from the TSX at the close of markets on January 30, 2026.

CREDIT FACILITIES

At April 24, 2026, we had a total of $7.8 billion of TCPL committed revolving credit facilities, of which $6.8 billion of short-term borrowing capacity remains available, net of $1.0 billion backstopping outstanding commercial paper balances. We also have arrangements in place for a further $2.0 billion of demand credit facilities, of which $1.2 billion remains available.

In addition, we have $2.1 billion of committed revolving credit facilities at certain of our subsidiaries and affiliates, of which $1.1 billion of borrowing capacity remains available at April 24, 2026, net of $1.0 billion backstopping outstanding commercial paper balances.

CONTRACTUAL OBLIGATIONS

Capital expenditure commitments at March 31, 2026 were approximately $1.3 billion (December 31, 2025 - approximately $0.8 billion), reflecting contractual commitments entered into for construction on U.S. natural gas pipelines primarily related to the construction costs associated with ANR and other pipeline projects.

There were no material changes to our contractual obligations in first quarter 2026 or to payments due in the next five years or thereafter. Refer to our 2025 Annual Report for additional information about our contractual obligations.

TC Energy First Quarter 2026 | 33

Financial risks and financial instruments

We are exposed to various financial risks and have strategies, policies and limits in place to manage the impact of these risks on our earnings, cash flows and, ultimately, shareholder value.

Risk management strategies, policies and limits are designed to ensure our risks and related exposures are in line with our business objectives and risk tolerance.

Refer to our 2025 Annual Report for additional information about the risks we face in our business which have not changed materially since December 31, 2025, other than as noted within this MD&A.

INTEREST RATE RISK

We utilize both short- and long-term debt to finance our operations which exposes us to interest rate risk. We typically pay fixed rates of interest on our long-term debt and floating rates on short-term debt including our commercial paper programs and amounts drawn on our credit facilities. A small portion of our long-term debt bears interest at floating rates. In addition, we are exposed to interest rate risk on financial instruments and contractual obligations containing variable interest rate components. We actively manage our interest rate risk using interest rate derivatives.

FOREIGN EXCHANGE RISK

A portion of our Mexico Natural Gas Pipelines' monetary assets and liabilities are peso-denominated, while our Mexico operations' financial results are denominated in U.S. dollars. Therefore, changes in the value of the Mexican peso against the U.S. dollar can affect our comparable earnings. In addition, foreign exchange gains or losses calculated for Mexico income tax purposes on the revaluation of U.S. dollar-denominated monetary assets and liabilities result in a peso-denominated income tax exposure for these entities, leading to fluctuations in Income (loss) from equity investments and Income tax expense (recovery) in the Condensed consolidated statement of income.

We actively manage a portion of our foreign exchange risk using foreign exchange derivatives. Refer to the Foreign exchange section for additional information.

We hedge a portion of our net investment in foreign operations (on an after-tax basis) with U.S. dollar-denominated debt as appropriate.

COUNTERPARTY CREDIT RISK

We have exposure to counterparty credit risk in a number of areas including:

•cash and cash equivalents

•accounts receivable

•available-for-sale assets

•fair value of derivative assets

•net investment in leases and certain contract assets in Mexico.

Market events causing disruptions in global energy demand and supply may contribute to economic uncertainties impacting a number of our customers. While the majority of our credit exposure is to large creditworthy entities, we maintain close monitoring and communication with those counterparties experiencing greater financial pressures. Refer to our 2025 Annual Report for more information about the factors that mitigate our counterparty credit risk exposure.

34 | TC Energy First Quarter 2026

We review financial assets carried at amortized cost for impairment using the lifetime expected loss of the financial asset at initial recognition and throughout the life of the financial asset. We use historical credit loss and recovery data, adjusted for our judgment regarding current economic and credit conditions, along with reasonable and supportable forecasts to determine if any impairment, should be recognized in Plant operating costs and other. At March 31, 2026, we had no significant credit risk concentrations, with the exception of the CFE, which represents approximately 33 per cent of gross exposure. At this time, there were no significant amounts past due or impaired. We recorded a pre-tax expense of $19 million on the expected credit loss provision on the TGNH net investment in leases and certain contract assets in Mexico for the three months ended March 31, 2026 (2025 – pre-tax recovery of $2 million). Refer to Note 12, Risk management and financial instruments, of our Condensed consolidated financial statements for additional information.

We have significant credit and performance exposure to financial institutions that hold cash deposits and provide committed credit lines and letters of credit that help manage our exposure to counterparties and provide liquidity in commodity, foreign exchange and interest rate derivative markets. Our portfolio of financial sector exposure consists primarily of highly-rated investment grade, systemically important financial institutions.

LIQUIDITY RISK

Liquidity risk is the risk that we will not be able to meet our financial obligations as they come due. We manage our liquidity risk by continuously forecasting our cash flows and ensuring we have adequate cash balances, cash flows from operations, committed and demand credit facilities and access to capital markets to meet our operating, financing and capital expenditure obligations under both normal and stressed economic conditions.

FINANCIAL INSTRUMENTS

With the exception of Long-term debt and Junior subordinated notes, our derivative and non-derivative financial instruments are recorded on the balance sheet at fair value unless they were entered into and continue to be held for the purpose of receipt or delivery in accordance with our normal purchase and sales exemptions and are documented as such. In addition, fair value accounting is not required for other financial instruments that qualify for certain accounting exemptions.

Derivative instruments

We use derivative instruments to reduce volatility associated with fluctuations in commodity prices, interest rates and foreign exchange rates. Derivative instruments, including those that qualify and are designated for hedge accounting treatment, are recorded at fair value.

The majority of derivative instruments that are not designated or do not qualify for hedge accounting treatment have been entered into as economic hedges to manage our exposure to market risk and are classified as held-for-trading. Changes in the fair value of held-for-trading derivative instruments are recorded in net income in the period of change. This may expose us to increased variability in reported operating results since the fair value of the held-for-trading derivative instruments can fluctuate significantly from period to period.

The recognition of gains and losses on derivatives for Canadian natural gas regulated pipeline exposures is determined through the regulatory process. Gains and losses arising from changes in the fair value of derivatives accounted for as part of RRA, including those that qualify for hedge accounting treatment, are expected to be refunded or recovered through the tolls charged by us. As a result, these gains and losses are deferred as regulatory liabilities or regulatory assets and are refunded to or collected from the ratepayers in subsequent years when the derivative settles.

Other information

CONTROLS AND PROCEDURES

Management, including our President and CEO and our CFO, evaluated the effectiveness of our disclosure controls and procedures as at March 31, 2026, as required by the Canadian securities regulatory authorities and by the SEC and concluded that our disclosure controls and procedures are effective at a reasonable assurance level.

There were no changes in first quarter 2026 that had or are likely to have a material impact on our internal controls over financial reporting.

CRITICAL ACCOUNTING ESTIMATES AND ACCOUNTING POLICY CHANGES

When we prepare financial statements that conform with U.S. GAAP, we are required to make estimates and assumptions that affect the timing and amounts we record for our assets, liabilities, revenues and expenses because these items may be affected by future events. We base the estimates and assumptions on the most current information available, using our best judgment. We also regularly assess the assets and liabilities themselves. In addition to the items discussed below, refer to our 2025 Annual Report for a listing of critical accounting estimates.

Impairment of goodwill

Goodwill is tested for impairment on an annual basis, or more frequently if events or changes in circumstances indicate it might be impaired. We can initially make this assessment based on qualitative factors. If we conclude that it is not more likely than not that the fair value of the reporting unit is greater than its carrying value, we will then perform a quantitative goodwill impairment test.

The estimated fair value in excess of the carrying value was less than 10 per cent on our Great Lakes reporting unit at the date of our last quantitative goodwill impairment test. Any future reductions in cash flow forecasts or adverse changes in other key assumptions could result in a future impairment of our goodwill balance.

Accounting changes

Our significant accounting policies have remained unchanged since December 31, 2025 other than as described in Note 2, Accounting changes, of our Condensed consolidated financial statements. A summary of our significant accounting policies is included in our 2025 Annual Report.

FACTORS AFFECTING QUARTERLY FINANCIAL INFORMATION BY BUSINESS SEGMENT

Quarter-over-quarter revenues and net income fluctuate for reasons that vary across our business segments. In addition to the factors below, our revenues and segmented earnings (losses) are impacted by fluctuations in foreign exchange rates, mainly related to our U.S. dollar-denominated operations and our peso-denominated exposure. Refer to the Foreign exchange section for additional information.

In our Natural Gas Pipelines business, except for seasonal fluctuations in short-term throughput volumes on U.S. pipelines, quarter-over-quarter revenues and segmented earnings (losses) generally remain relatively stable during any fiscal year. Over the long term, however, they fluctuate because of:

•regulatory decisions

•negotiated settlements with customers

•newly constructed assets being placed in service

•acquisitions and divestitures

•natural gas marketing activities and commodity prices

•developments outside of the normal course of operations

•certain fair value adjustments

•provisions for expected credit losses on net investment in leases and certain contract assets in Mexico.

38 | TC Energy First Quarter 2026

In Power and Energy Solutions, quarter-over-quarter revenues and segmented earnings (losses) are affected by:

•weather

•customer demand

•newly constructed assets being placed in service

•acquisitions and divestitures

BASIS OF PRESENTATION

These Condensed consolidated financial statements of TC Energy Corporation (TC Energy or the Company) have been prepared by management in accordance with U.S. GAAP. The accounting policies applied are consistent with those outlined in TC Energy’s annual audited Consolidated financial statements for the year ended December 31, 2025, except as described in Note 2, Accounting changes. Capitalized and abbreviated terms that are used but not otherwise defined herein are identified in TC Energy’s 2025 Annual Report.

These Condensed consolidated financial statements reflect adjustments, all of which are normal recurring adjustments that are, in the opinion of management, necessary to reflect fairly the financial position and results of operations for the respective periods. These Condensed consolidated financial statements do not include all disclosures required in the annual financial statements and should be read in conjunction with the 2025 audited Consolidated financial statements included in TC Energy’s 2025 Annual Report. Certain comparative figures have been adjusted to reflect the current period's presentation.

On October 1, 2024, TC Energy completed the spinoff of its Liquids Pipelines business into the new public company, South Bow Corporation (South Bow) (the Spinoff Transaction). The results of the Liquids Pipelines business are presented as discontinued operations and have been excluded from continuing operations and segment disclosures for all periods presented.

Earnings for interim periods may not be indicative of results for the fiscal year in certain of the Company’s segments primarily due to:

•Natural gas pipelines segments – the timing of regulatory decisions and negotiated rate case settlements as well as seasonal fluctuations in short-term throughput volumes on U.S. pipelines and marketing activities

•Power and Energy Solutions – the impacts of seasonal weather conditions on customer demand, market supply and prices of natural gas and power as well as maintenance outages in certain of the Company’s investments in electrical power generation plants and Canadian non-regulated natural gas storage facilities and marketing activities.

In addition to the factors mentioned above, revenues and segmented earnings are impacted by fluctuations in foreign exchange rates, mainly related to the Company's U.S. dollar-denominated operations and Mexican peso-denominated exposure.

Use of Estimates and Judgments

In preparing these Condensed consolidated financial statements, TC Energy is required to make estimates and assumptions that affect both the amount and timing of recording assets, liabilities, revenues and expenses since the determination of these items may be dependent on future events. The Company uses the most current information available and exercises careful judgment in making these estimates and assumptions. In the opinion of management, these Condensed consolidated financial statements have been properly prepared within reasonable limits of materiality and within the framework of the Company’s significant accounting policies included in the annual audited Consolidated financial statements for the year ended December 31, 2025, except as described in Note 2, Accounting changes.

ACCOUNTING CHANGES

Future Accounting Changes

Disaggregation of Income Statement Expenses

In November 2024, the FASB issued new guidance requiring additional disclosure on the nature of expenses included in the income statement. The new standard requires disclosures about specific types of expenses included in the expense captions presented on the face of the income statement as well as disclosures about selling expenses. The new guidance is effective for annual periods beginning January 1, 2027 and interim periods beginning January 1, 2028. Early adoption is permitted. The guidance is applied prospectively with retrospective application permitted. The Company is currently assessing the impact of the standard on the Company's consolidated financial statements.

Internal-Use Software

In September 2025, the FASB issued updated guidance for accounting for internal-use software costs. The updated guidance removes references to project development stages and outlines revised guidance for when capitalization begins for internal-use software costs. The guidance is effective for annual and interim periods beginning January 1, 2028. Early adoption is permitted as of the beginning of an annual reporting period. The guidance can be applied prospectively, retrospectively, or with a modified transition approach. The Company is currently assessing the impact of the standard on the Company's consolidated financial statements.

Hedge Accounting Improvements

In November 2025, the FASB issued new guidance to further align hedge accounting with the economics of an entity's risk management activities. The amendments are intended to allow entities to achieve and maintain hedge accounting for highly effective hedges of forecasted transactions. The new guidance is effective for interim and annual reporting periods beginning January 1, 2027. Early adoption is permitted. The guidance is applied on a prospective basis for all hedging relationships that exist at the date of adoption. The Company is currently assessing the impact of the standard on the Company's consolidated financial statements.

Government Grants

In December 2025, the FASB established authoritative guidance on the recognition, measurement and presentation requirements for government grants received. The new guidance is effective for annual and interim periods beginning January 1, 2029. Early adoption is permitted. The guidance can be applied with a modified prospective, a modified retrospective, or a retrospective approach. The Company is currently assessing the impact of the standard on the Company's consolidated financial statements.

Contract Balances

(unaudited - millions of Canadian $)	March 31, 2026	December 31, 2025	Affected line item on the Condensed consolidated balance sheet
Receivables from contracts with customers	1,665	1,822	Accounts receivable
Contract assets	295	216	Other current assets
Long-term contract assets	622	627	Other long-term assets
Contract liabilities1	73	46	Accounts payable and other

1During the three months ended March 31, 2026, $19 million (2025 – $13 million) of revenues were recognized that were included in contract liabilities at the beginning of the period.

Contract assets and long-term contract assets primarily relate to the Company’s right to revenues for services completed but not invoiced at the reporting date on long-term committed capacity natural gas pipelines contracts. The change in contract assets is primarily related to the transfer to Accounts receivable when these rights become unconditional and the customer is invoiced, as well as the recognition of additional revenues that remain to be invoiced. Contract liabilities primarily represent unearned revenue for contracted services.

Future Revenues from Remaining Performance Obligations

At March 31, 2026, future revenues from long-term pipeline capacity arrangements and transportation as well as natural gas storage and other contracts extending through 2055 are approximately $33.7 billion, of which approximately $5.7 billion is expected to be recognized during the remainder of 2026.

INCOME TAXES

Effective Tax Rates

The effective income tax rates were 18 per cent and 20 per cent for the three months ended March 31, 2026 and 2025, respectively. The decrease in the effective income tax rate is primarily due to the impact of Mexico foreign exchange exposure partially offset by a change in the geographic and business mix of earnings and higher flow-through income taxes.

RISK MANAGEMENT AND FINANCIAL INSTRUMENTS

Risk Management Overview

TC Energy has exposure to market risk and counterparty credit risk and has strategies, policies and limits in place to manage the impact of these risks on its earnings, cash flows and, ultimately, shareholder value.

Counterparty Credit Risk

TC Energy’s exposure to counterparty credit risk includes its cash and cash equivalents, accounts receivable, available-for-sale assets, the fair value of derivative assets, net investment in leases and certain contract assets in Mexico.

Market events causing disruptions in global energy demand and supply may contribute to economic uncertainties impacting a number of TC Energy's customers. While the majority of the Company's credit exposure is to large creditworthy entities, TC Energy maintains close monitoring and communication with those counterparties experiencing greater financial pressures. Refer to TC Energy's 2025 Annual Report for more information about the factors that mitigate the Company's counterparty credit risk exposure.

The Company reviews financial assets carried at amortized cost for impairment using the lifetime expected loss of the financial asset at initial recognition and throughout the life of the financial asset. TC Energy uses historical credit loss and recovery data, adjusted for management's judgment regarding current economic and credit conditions, along with reasonable and supportable forecasts to determine any impairment, which is recognized in Plant operating costs and other.

For the three months ended March 31, 2026, the Company recorded an expense of $17 million (2025 – recovery of $2 million) on the expected credit loss (ECL) provision before tax with respect to the net investment in leases associated with in-service TGNH pipelines.

At March 31, 2026, the balance of the ECL provision was $162 million (December 31, 2025 – $141 million) with respect to the net investment in leases associated with in-service TGNH pipelines.

The ECL provision is driven primarily by a probability of default measure for the counterparty, which is calculated using information published by an external third party.

Other than the ECL provision noted above, the Company had no significant credit losses at March 31, 2026, and there were no significant credit risk concentrations or amounts past due or impaired.

TC Energy has significant credit and performance exposure to financial institutions that hold cash deposits and provide committed credit lines and letters of credit that help manage the Company's exposure to counterparties and provide liquidity in commodity, foreign exchange and interest rate derivative markets. TC Energy's portfolio of financial sector exposure consists primarily of highly-rated investment grade, systemically important financial institutions.

Net Investment in Foreign Operations

The Company hedges a portion of its net investment in foreign operations (on an after-tax basis) with U.S. dollar-denominated debt as appropriate. The notional amounts and fair values of U.S. dollar-denominated debt designated as a net investment hedge were as follows:

(unaudited - millions of Canadian $, unless otherwise noted)	March 31, 2026	December 31, 2025
Notional amount	23,900 (US 17,100)	25,700 (US 18,700)
Fair value	23,800 (US 17,100)	25,800 (US 18,800)

Non-Derivative Financial Instruments

Fair value of non-derivative financial instruments

Available-for-sale assets are recorded at fair value which is calculated using quoted market prices where available in addition to the Company's LMCI equity securities which are classified in Level I of the fair value hierarchy. Certain other non-derivative financial instruments included in Cash and cash equivalents, Accounts receivable, Other current assets, Net investment in leases, Restricted investments, Other long-term assets, Notes payable, Accounts payable and other, Dividends payable, Accrued interest and Other long-term liabilities have carrying amounts that approximate their fair value due to the nature of the item or the short time to maturity.

Credit risk has been taken into consideration when calculating the fair value of non-derivative financial instruments.

Balance sheet presentation of non-derivative financial instruments

The following table details the fair value of non-derivative financial instruments, excluding those where carrying amounts approximate fair value and would be classified in Level II of the fair value hierarchy:

1Long-term debt is recorded at amortized cost, except for $4.7 billion (December 31, 2025 – $4.0 billion) that is attributed to hedged risk and recorded at fair value.

2Net income (loss) for the three months ended March 31, 2026 included unrealized gains of $26 million (2025 – unrealized losses of $88 million) for fair value adjustments attributable to the hedged interest rate risk associated with interest rate swap fair value hedging relationships.

3Realized gains (losses) on the sale of LMCI restricted investments are determined using the average cost basis.

Derivative Instruments

Fair value of derivative instruments

The fair value of foreign exchange and interest rate derivatives has been calculated using the income approach which uses period-end market rates and applies a discounted cash flow valuation model. The fair value of commodity derivatives has been calculated using quoted market prices where available. In the absence of quoted market prices, third-party broker quotes or other valuation techniques have been used. The fair value of options has been calculated using the Black-Scholes pricing model. Credit risk has been taken into consideration when calculating the fair value of derivative instruments. Unrealized gains and losses on derivative instruments are not necessarily representative of the amounts that will be realized on settlement.

In some cases, even though the derivatives are considered to be effective economic hedges, they do not meet the specific criteria for hedge accounting treatment or are not designated as a hedge and are accounted for at fair value with changes in fair value recorded in net income in the period of change. This may expose the Company to increased variability in reported earnings because the fair value of the derivative instruments can fluctuate significantly from period to period.

TC Energy First Quarter 2026 | 61

The recognition of gains and losses on derivatives for Canadian natural gas regulated pipeline exposures is determined through the regulatory process. Gains and losses arising from changes in the fair value of derivatives accounted for as part of rate-regulated accounting, including those that qualify for hedge accounting treatment, are expected to be refunded or recovered through the tolls charged by the Company. As a result, these gains and losses are deferred as regulatory liabilities or regulatory assets and are refunded to or collected from the rate payers in subsequent years when the derivative settles.

Offsetting of derivative instruments

The Company enters into derivative contracts with the right to offset in the normal course of business as well as in the event of default. TC Energy has no master netting agreements; however, similar contracts are entered into containing rights to offset. The Company has elected to present the fair value of derivative instruments with the right to offset on a gross basis on the Condensed consolidated balance sheet. The following tables show the impact on the presentation of the fair value of derivative instrument assets and liabilities had the Company elected to present these contracts on a net basis:

With respect to the derivative instruments presented above, the Company provided cash collateral of $159 million and letters of credit of $151 million at March 31, 2026 (December 31, 2025 – $93 million and $73 million, respectively) to its counterparties. At March 31, 2026, the Company held cash collateral of $3 million and $128 million of letters of credit (December 31, 2025 – less than $1 million and $102 million, respectively) from counterparties on asset exposures. Only cash collateral that has been transferred and held at the reporting date is included in collateral disclosures. Margin payable but not yet posted of $17 million at March 31, 2026 (December 31, 2025 – $4 million) represents a financial obligation and is excluded from provided cash collateral balances.

66 | TC Energy First Quarter 2026

Credit-risk-related contingent features of derivative instruments

Derivative contracts entered into to manage market risk often contain financial assurance provisions that allow parties to the contracts to manage credit risk. These provisions may require collateral to be provided if a credit-risk-related contingent event occurs, such as a downgrade in the Company’s credit rating to non-investment grade. The Company may also need to provide collateral if the fair value of its derivative financial instruments exceeds pre-defined exposure limits.

Based on contracts in place and market prices at March 31, 2026, the aggregate fair value of all derivative instruments with credit-risk-related contingent features that were in a net liability position was $8 million (December 31, 2025 – net liability of $5 million), for which the Company has provided no collateral in the normal course of business. If the credit‑risk‑related contingent features in these agreements were triggered on March 31, 2026, the Company would have been required to provide collateral equal to the fair value of the related derivative instruments discussed above. Collateral may also need to be provided should the fair value of derivative instruments exceed pre-defined contractual exposure limit thresholds. The Company has sufficient liquidity in the form of cash and undrawn committed revolving credit facilities to meet these contingent obligations should they arise.

Fair Value Hierarchy

The Company’s financial assets and liabilities recorded at fair value have been categorized into three categories based on a fair value hierarchy.

Levels	How fair value has been determined
Level I	Quoted prices in active markets for identical assets and liabilities that the Company has the ability to access at the measurement date. An active market is a market in which frequency and volume of transactions provides pricing information on an ongoing basis.
Level II	This category includes interest rate and foreign exchange derivative assets and liabilities where fair value is determined using the income approach and commodity derivatives where fair value is determined using the market approach.<br><br>Inputs include published exchange rates, interest rates, interest rate swap curves, yield curves and broker quotes from external data service providers.
Level III	This category includes long-dated commodity transactions in certain markets where liquidity is low. The Company uses the most observable inputs available or alternatively long-term broker quotes or negotiated commodity prices that have been contracted for under similar terms in determining an appropriate estimate of these transactions. Where appropriate, these long-dated prices are discounted to reflect the expected pricing from the applicable markets.<br><br>There is uncertainty caused by using unobservable market data which may not accurately reflect possible future changes in fair value.

The fair value of the Company’s derivative assets and liabilities measured on a recurring basis, including both current and non‑current portions, were categorized as follows:

The Company has entered into contracts which commenced in 2025 and 2026 to sell 50 MW of power with terms ranging from 15 to 20 years provided from specified renewable sources in the Province of Alberta. The fair value of these contracts is classified in Level III of the fair value hierarchy and is based on the assumption that the contract volumes will be sourced approximately 70 per cent from wind generation, 10 per cent from solar generation and 20 per cent from the market (December 31, 2025 – 80 per cent wind generation, 10 per cent solar generation and 10 per cent market).

COMMITMENTS, CONTINGENCIES AND GUARANTEES

Commitments

Capital expenditure commitments include obligations related to the construction of growth projects and are based on the projects proceeding as planned. At March 31, 2026, TC Energy had approximately $1.3 billion of capital expenditure commitments (December 31, 2025 – approximately $0.8 billion) reflecting contractual commitments entered into for construction on U.S. natural gas pipelines, primarily related to the construction costs associated with ANR and other pipeline projects.

Contingencies

TC Energy and its subsidiaries are subject to various legal proceedings, arbitrations and actions arising in the normal course of business. While the final outcome of such legal proceedings and actions cannot be predicted with certainty, it is the opinion of management that the resolution of such normal course proceedings and actions will not have a material impact on the Company's consolidated financial position or results of operations.

Guarantees

TC Energy and its partner on the Sur de Texas pipeline, IEnova, have jointly guaranteed the financial performance of the entity which owns the pipeline. Such agreements include a guarantee and a letter of credit which are primarily related to the delivery of natural gas.

TC Energy and its joint venture partner on Bruce Power, BPC Generation Infrastructure Trust, have each severally guaranteed certain contingent financial obligations of Bruce Power related to a lease agreement and contractor and supplier services.

The Company and its partners in certain other jointly-owned entities have either (i) jointly and severally, (ii) jointly or (iii) severally guaranteed the financial performance of these entities. Such agreements include guarantees and letters of credit which are primarily related to construction services and the payment of liabilities. For certain of these entities, any payments made by TC Energy under these guarantees in excess of its ownership interest are to be reimbursed by its partners.

The carrying value of these guarantees has been included in Other long-term liabilities on the Condensed consolidated balance sheet. Information regarding the Company’s guarantees is as follows:

CEO Message

Throughout the first quarter of 2026, TC Energy continued to build on momentum and demonstrate strong execution against a clear set of strategic priorities. Our unwavering focus on safety and operational excellence continues to support the availability and reliability of our assets that continue to drive strong operational and financial results. For the three months ended Mar. 31, 2026, comparable EBITDA increased 14 per cent and segmented earnings increased 10 per cent compared to first quarter 2025. Our consistent results reinforce the strength and resilience of our low-risk business model and our ability to deliver solid growth and repeatable performance despite ongoing macroeconomic volatility. Additionally, during Winter Storm Fern, our team continued to deliver exceptional reliability that contributed in part to the seven delivery records we achieved on our system during the quarter. We remain focused on maximizing the value of our assets through safety and operational excellence, executing our selective portfolio of growth projects, and ensuring financial strength and agility.

Sustained growth in natural gas and power demand in the U.S. continues to translate into attractive investment opportunities across our diversified portfolio. Consistent with our capital allocation priorities, we have announced a strategic expansion project on our Columbia Gas system that reinforces visibility to incremental growth into the next decade. The US$1.5 billion Appalachia Supply Project on our Columbia Gas system extends our reach into a corridor that serves multiple high‑growth power and industrial markets. The expansion project is supported by a 20‑year take‑or‑pay contract backed by an investment‑grade utility and is expected to deliver a 7.3x build multiple. The project is designed to provide up to 0.8 Bcf/d of capacity to facilitate expanded new natural gas-fired power generation and has an anticipated in-service date in 2030. The project is capable of up to 2.0 Bcf/d through future expansions, creating additional opportunities to pursue capital‑efficient, high‑value growth projects as diversified demand from electrification, economic development, and data centres is anticipated to accelerate long‑duration load growth in the U.S. Heartland market. The project represents a deliberate investment in a strategic, high‑growth corridor that further strengthens the long‑term competitive positioning of the Columbia Gas Transmission system and establishes a durable platform for repeatable value creation into the next decade.

Supported by strong customer demand, on Feb. 9, 2026, we launched a non-binding expansion project open season on our Crossroads Pipeline system for up to 1.5 Bcf/d of capacity to serve growing markets in Northern Indiana, Illinois, Iowa, and South Dakota. The open season was 2.5 times oversubscribed, reflecting the asset’s unique connectivity and bi-directional flexibility. By linking multiple major pipeline systems, the Crossroads pipeline is well positioned to support the anticipated substantial growth in Midwest power demand, and our established footprint enables capital‑efficient expansion and reduced execution risk. The Crossroads open season builds off the momentum of the non-binding expansion project open season on our Columbia Gas Transmission system that closed on Jan. 9 , 2026 and received bids at three times the proposed project capacity. These developments illustrate how connectivity between our systems enables highly competitive pathways from premium supply to high‑quality demand markets and reinforces the value and scalability of our integrated footprint.

Broader market dynamics, including volatility and structural change in the global LNG market, continue to underscore our role as a critical conduit for North American supply to global markets. As the only company serving every major LNG export shoreline in North America, transporting approximately 30 per cent of feedgas bound for export, we continue to see strong demand across our system. Deliveries to U.S. LNG facilities increased 12 per cent year‑over‑year, averaging 3.9 Bcf/d in the first quarter 2026. Against this backdrop, we reached an important milestone as Coastal GasLink LP entered into commercial agreements with LNG Canada, establishing a framework to advance a proposed CGL Phase 2 Expansion. The commercial structure of the agreements includes limits on CGL’s capital commitments and overall liability for construction cost and schedule risks, reflecting our disciplined approach to risk allocation as we advance critical infrastructure projects across North America.

In both Canada and the U.S., we made meaningful progress reaching settlement agreements with customers on the Canadian Mainline, ANR and Great Lakes. On the Canadian Mainline, we filed an application with the CER seeking approval of a four‑year negotiated settlement covering the period from January 2027 through December 2030, maintaining a return on equity of 10.1 per cent on 40 per cent deemed common equity, with an incentive mechanism designed to encourage cost management and revenue optimization and provides the opportunity to outperform the approved rate of return. In addition, TC Energy has committed up to $200 million of capital to support incremental capacity, with targeted returns that exceed the

approved return on equity. On ANR, we reached a settlement‑in‑principle with customers in the Section 4 rate case, which is expected to include an increase relative to pre-filed rates, subject to revision following completion and approval of settlement terms, which we anticipate in third quarter of 2026. On Great Lakes, we reached a settlement-in-principle with customers, subject to revision following completion and approval of settlement terms, which we anticipate in fourth quarter 2026. Together, these developments reinforce the stability and long‑term strength of our regulated earnings profile.

Execution remained strong across the portfolio. During the quarter, we placed approximately $0.4 billion of capacity projects into service on the NGTL System, including $0.1 billion of MYGP projects, on time and on budget. We completed construction of the approximately $0.3 billion Berland River unit, a non‑emitting electric compressor on the Valhalla North and Berland River project which is expected to be operational in the second half of 2026. At Bruce Power, we continue to track to cost and schedule on the Major Component Replacement (MCR) Unit 3 and 4.

Disciplined execution and prudent capital spending continue to strengthen the balance sheet and advance our strategic priorities, while keeping us on track to achieve our long‑term target of 4.75x debt-to-EBITDA.1 Together, these milestones reflect the strength and resilience of our asset base, our ability to execute reliably at scale, and our focused, capital‑efficient approach to growth that enhances long‑term value for TC Energy shareholders.

Dividends

TC Energy’s Board of Directors declared a quarterly dividend of $0.8775 per common share for the quarter ending June 30, 2026, equivalent to $3.51 on an annualized basis. The common share dividend is payable on July 31, 2026, to shareholders of record at the close of business on June 30, 2026.

The Board of Directors also declared dividends on the outstanding Cumulative First Preferred Shares (preferred shares). Information related to the preferred shares dividends are available on our website under TC Energy – Shareholder Information.

1 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 on non-GAAP measures, refer to the non-GAAP measures of this news release. These measures do not have any standardized meaning under GAAP and therefore are unlikely to be comparable to similar measures presented by other companies.

Non-GAAP and Supplementary Financial Measure

This release contains references to the following non-GAAP measures: comparable EBITDA, comparable earnings, comparable earnings per common share and comparable funds generated from operations. It also contains references to debt-to-EBITDA, a non-GAAP ratio, which is calculated using adjusted debt and adjusted comparable EBITDA, each of which are non-GAAP measures. 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. Refer to: (i) each business segment for a reconciliation of comparable EBITDA to segmented earnings (losses); (ii) Consolidated results section for reconciliations of comparable earnings and comparable earnings per common share to Net income attributable to common shares and Net income per common share, respectively; and (iii) Financial condition section for a reconciliation of comparable funds generated from operations to Net cash provided by operations. Refer to the Non-GAAP Measures section of the MD&A in our most recent quarterly report for more information about the non-GAAP measures we use. The MD&A is included with, and forms part of, this release. The MD&A can be found on SEDAR+ at www.sedarplus.ca under TC Energy's profile.

With respect to non-GAAP measures used in the calculation of debt-to-EBITDA, 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 the sum of comparable EBITDA from continuing operations and comparable EBITDA from discontinued operations 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) loss from equity investments and a Loan from affiliate as reported in our Consolidated statement of cash flows which we believe is more reflective of the cash flows available to TC Energy to service our debt and other long-term commitments. Beginning in 2025, we entered into a subordinated demand revolving credit facility to borrow funds from the Sur de Texas joint venture and received proceeds totaling $111 million during the year. 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. See the Reconciliation section for reconciliations of adjusted debt and adjusted comparable EBITDA for the years ended Dec. 31, 2023, 2024 and 2025.

This release contains references to build multiple, which is non-GAAP ratio which is calculated using capital expenditures and comparable EBITDA, of which comparable EBITDA is a non-GAAP measure. We believe build multiple provides investors with a useful measure to evaluate capital projects.

This release also contains references to net capital expenditures, which is a supplementary financial measure. Net capital expenditures represent capital costs incurred for growth projects, maintenance capital expenditures, contributions to equity investments and projects under development, adjusted for the portion attributed to non-controlling interests in the entities we control. Net capital expenditures reflect capital costs incurred during the period, excluding the impact of timing of cash payments. We use net capital expenditures as a key measure in evaluating our performance in managing our capital spending activities in comparison to our capital plan.
