[6-K] TC ENERGY CORP Current Report (Foreign Issuer)

Rhea-AI Filing Summary

TC Energy Corporation reported strong fourth quarter and full-year 2025 results driven by record natural gas flows and solid contracted earnings. Fourth quarter comparable EBITDA from continuing operations rose to $3.0 billion from $2.6 billion, while segmented earnings increased to $2.2 billion from $1.9 billion.

For 2025, comparable EBITDA from continuing operations grew to $11.0 billion from $10.0 billion, and segmented earnings were $8.0 billion, flat with 2024. Fourth quarter comparable earnings from continuing operations were $1.0 billion or $0.98 per share, down from $1.1 billion or $1.05 per share a year earlier.

The company highlighted 15 system flow records and strong North American gas demand. The Board approved a 3.2% increase in the quarterly dividend to $0.8775 per share (annualized $3.51), marking 26 consecutive years of growth. For 2026, TC Energy expects higher comparable EBITDA of $11.6–$11.8 billion and net capital expenditures of $5.5–$6.0 billion, supported by a roughly $21 billion secured project backlog and continued expansion in its Canadian, U.S. and Mexican natural gas pipeline networks and Bruce Power.

Insights

Infrastructure & Pipelines Analyst

EBITDA is growing and the dividend is rising, but per-share earnings are slightly softer.

TC Energy shows healthy underlying operations with 2025 comparable EBITDA from continuing operations rising to $11.0 billion from $10.0 billion, helped by higher regulated pipeline earnings and completion of the Southeast Gateway pipeline. Q4 EBITDA grew about 13%, and segmented earnings rose roughly 15%.

However, comparable earnings from continuing operations slipped to $3.65 billion or $3.51 per share from $3.87 billion or $3.73 per share, as higher depreciation, lower AFUDC and higher taxes offset operating growth. Net income from continuing operations also declined versus 2024.

The Board approved a 3.2% quarterly dividend increase to $0.8775 per share, with a multi-year capital plan targeting $5.5–$6.0 billion of net capital expenditures in 2026. Management guides to higher 2026 comparable EBITDA of $11.6–$11.8 billion, supported by a $21.4 billion secured project backlog and continued Bruce Power life-extension work.

Quarterly Report to Shareholders

TC Energy reports fourth quarter and full-year 2025 results

Strongest safety performance in five years drives 15 flow records and solid financial results

Progress in commercial discussions strengthens line of sight to incremental project announcements in 2026

Raises dividend for 26th consecutive year

CALGARY, Alberta – Feb. 13, 2026 – TC Energy Corporation (TSX, NYSE: TRP) (TC Energy or the Company) released its fourth quarter and full-year 2025 results today. François Poirier, TC Energy’s President and Chief Executive Officer commented, "Our safety-first culture is driving exceptional operational performance, leading to 15 flow records across our systems in 2025. Strong asset availability and reliability drove a 13 per cent year-over-year increase in fourth quarter comparable EBITDA1 and a 15 per cent increase in segmented earnings over the same period." Poirier continued, "As commercial discussions advance across a diverse set of high-quality opportunities, we remain confident in our ability in 2026 to fully allocate $6 billion of net annual capital expenditures through 2030 and have greater visibility to potentially surpass this level of investment in the latter part of the decade. Aligned with this momentum and clear line of sight to sustained growth, our Board of Directors approved a 3.2 per cent increase in quarterly common share dividend, marking our 26th consecutive year of dividend growth."

CEO Message

This was a defining year for TC Energy. Our 2025 performance demonstrates the strength of our strategy and reflects disciplined execution against a clear set of strategic priorities. During a period marked by heightened geopolitical risks, trade policy uncertainty and market volatility, our utility‑like, low‑risk business model continues to prove resilient. With 98 per cent of comparable EBITDA underpinned by rate regulated or long-term take-or-pay contracts, we maintain limited commodity exposure and strong visibility to stable, long-term cash flows. For the three months ending Dec. 31, 2025, comparable EBITDA increased approximately 13 per cent, and segmented earnings increased by approximately 15 per cent compared to the same period in 2024. For the twelve months ending Dec. 31, 2025, comparable EBITDA increased approximately nine per cent and segmented earnings increased by approximately one per cent compared to the same period in 2024.

Our financial results are directly enabled by our strongest safety performance in the last five years. This focus is driving exceptional performance from our operations and has allowed us to set 15 delivery records across our systems in 2025. In the fourth quarter 2025 and early 2026, record power demand from data centres, coal-to-gas conversions and LNG exports drove all-time delivery records across our U.S. and Canadian Natural Gas Pipeline Systems of 39.9 Bcf and 33.2 Bcf, respectively. The strong availability and reliability of our assets enable us to consistently meet incremental customer demand and underscores the value of our commitment to safety and operational excellence.

In 2025 we successfully placed $8.3 billion of projects into service on time, over 15 per cent under budget – demonstrating our ongoing commitment to project execution excellence. During the fourth quarter, we placed critical infrastructure projects into service, including the VR project on our Columbia system and the WR project on our ANR system in Wisconsin. Following our ninth consecutive year of fully contracted storage capacity, we added incremental value by placing the ANR Storage Optimization project into service. This enhancement expands our ability to respond to rising power generation demand in the U.S. Midwest, strengthening system flexibility and reinforcing the long‑term value of our storage portfolio. Looking ahead to 2026, we continue to expect to place approximately $4 billion of capital into service. This includes the Bison XPress Project on our Northern Border Pipeline, the remainder of the Valhalla North and Berland River Project on the NGTL System, as well as Bruce Power Unit 3 as part of the MCR program. Bruce Power’s consistent and strong track record of execution continue to position the asset to deliver stable, enduring value while meeting Ontario’s growing need for affordable, non-emitting, reliable power.

Strong results and consistent delivery on our capital program continue to strengthen our financial position and enhance our flexibility. We remain on track to deliver our long-term debt-to-EBITDA1 target. We believe this continued discipline positions us to capture meaningful growth opportunities emerging from our differentiated exposure to the fastest growing segments of the energy market – natural gas and power. Our outlook for North American natural gas demand expects an increase of 45 Bcf/d to approximately 170 Bcf/d between 2025 and 2035, driven by LNG exports, rising power generation and increasing reliability needs from local distribution companies. Building on these favourable underlying fundamentals, we are advancing opportunities to deploy capital and unlock incremental value across our existing footprint.

As commercial discussions advance across a diverse set of high-quality opportunities, we remain confident in our ability in 2026 to fully allocate $6 billion of net annual capital expenditures through 2030 and have greater visibility to potentially surpass this level of investment in the latter part of the decade. We will remain disciplined in our capital allocation, targeting build multiples in the five to seven times range, and continue to de-risk these opportunities ahead of sanctioning. This further strengthens our conviction in announcing additional projects in 2026.

Reflecting the sustained increase in natural gas demand, in the fourth quarter we sanctioned $0.6 billion of in-corridor projects that strengthen the long-term visibility of our growth profile and exemplify our disciplined approach to capital allocation. Building on this progress, we are also advancing early-stage commercial initiatives supported by growing market interest. On Jan. 9, 2026, we successfully closed a non-binding expansion project open season on our Columbia Gas

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.

Transmission system for up to 0.5 Bcf/d of incremental capacity to serve the Columbus area, including New Albany. Robust demand from power‑load growth driven by data centres resulted in approximately 1.5 Bcf/d of total bids – three times the proposed project capacity – highlighting the strength of the market and the value of our strategic footprint. In addition, 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. The potential Crossroads Expansion project would serve growing markets in Northern Indiana, Illinois, Iowa, and South Dakota, in response to recently announced power generation and data centre developments in the U.S. Midwest. The open season is expected to close in mid-March 2026. These developments reinforce our visibility into durable, long-term value creation.

Through disciplined capital allocation and consistent project execution, TC Energy has built a differentiated portfolio supported by diversified, low-risk growth opportunities that extend through the end of the decade and beyond. As we turn to 2026, we will build on this momentum with the same discipline that delivered results in 2025. Our priorities remain unchanged: delivering solid growth, low risk and repeatable performance by maximizing the value of our assets through safety and operational excellence, executing our selective portfolio of growth projects, and ensuring financial strength and agility.

Dividends

Consistent with our outlook, TC Energy’s Board of Directors approved a 3.2 per cent increase in the quarterly common share dividend of $0.8775 per common share for the quarter ending March 31, 2026, equivalent to $3.51 on an annualized basis. The common share dividend is payable on April 30, 2026, to shareholders of record at the close of business on March 31, 2026. This marks the 26th consecutive year of dividend increase.

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.

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 and the discontinued operations section for a reconciliation of comparable EBITDA to segmented earnings (losses); (ii) Consolidated results section and the discontinued operations 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.

Fourth quarter 2025 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 and comparable earnings per common share from continuing and discontinued operations and comparable funds generated from operations are all non-GAAP measures. Refer to page 6 for more information about the non-GAAP measures we use, as well as the Financial results section in each business segment and Discontinued operations sections for reconciliations to the most directly comparable GAAP measures.

Discussions throughout this news release are based on continuing operations unless otherwise noted.

NON-GAAP MEASURES

This news release 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 news release 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; 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. These measures are applicable to our continuing and discontinued operations. Quantitative reconciliations of our comparable measures to their GAAP measures and a discussion of specific adjustments made for the three months and year ended December 31, 2025 and comparative periods can be found on pages 7 and 8, each business segment section and the Cash provided by operating activities section. Non-GAAP measures for discontinued operations are found in the Discontinued operations section on     page 31.

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 funds generated from operations			net cash provided by operations

6 | TC Energy Fourth Quarter News Release 2025

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 and the Discontinued operations section 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 Cash provided by operating activities 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 on 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 page 8 as well as the Discontinued operations section for reconciliations to Net income (loss) attributable to common shares and Net income (loss) per common share for our continuing operations and discontinued operations.

Comparable earnings and comparable earnings per common share - from continuing operations

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

Fourth quarter 2025 results

•a pre-tax impairment charge of $110 million for certain Power and Energy Solutions projects following our decision to discontinue development along with updated forecast assumptions as we refocus our Power and Energy Solutions strategy

•pre-tax unrealized foreign exchange losses, net, of $47 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 recovery of $4 million on the expected credit loss provision related to TGNH net investment in leases, net of     non-controlling interest as well as certain contract assets in Mexico.

Fourth quarter 2024 results

•a pre-tax net gain on debt extinguishment of $228 million related to the purchase and cancellation of certain senior unsecured notes and medium term notes and the retirement of outstanding callable notes in October 2024

1In 2023, TCPL and TGNH entered into 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. Refer to Note 27, Risk management and financial instruments, in the Consolidated financial statements of our 2025 Annual Report for additional information.

3In October 2024, TCPL commenced and completed our cash tender offers to purchase and cancel certain senior unsecured notes and medium term notes
at a 7.73 per cent weighted average discount. In addition, we retired outstanding callable notes at par. These extinguishments of debt resulted in a pre-tax
net gain of $228 million, primarily due to fair value discounts and unamortized debt issue costs. The net gain on debt extinguishment was recorded in Interest expense in the Condensed consolidated statement of income. Refer to Note 19, Long-term debt, in the Consolidated financial statements of our 2025 Annual Report for additional information.

4In 2024, we recognized expenses related to the Focus Project for external consulting and severance, some of which are not recoverable through regulatory and commercial tolling structures.

Comparable EBITDA from continuing operations

Fourth quarter 2025 versus fourth quarter 2024

Comparable EBITDA from continuing operations increased by $345 million for the three months ended December 31, 2025 compared to the same period in 2024 primarily due to the net result of the following:

•increased U.S. dollar-denominated EBITDA from 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, incremental earnings from projects placed in service, additional contract sales and higher realized earnings related to our U.S. natural gas marketing business

•increased U.S. dollar-denominated EBITDA from Mexico Natural Gas Pipelines mainly due to higher earnings in TGNH primarily related to the completion of the Southeast Gateway pipeline in second quarter 2025, partially offset by lower equity earnings from Sur de Texas as a result of peso-denominated financial exposure and higher income tax expense mainly related to foreign exchange impacts of U.S dollar-denominated liabilities

•increased EBITDA in Canadian Natural Gas Pipelines mainly due to higher flow-through depreciation and incentive earnings on the NGTL System and Mainline

•decreased Power and Energy Solutions EBITDA mainly attributable to lower net contributions from Bruce Power due to reduced generation primarily resulting from the Unit 4 Major Component Replacement (MCR), partially offset by a higher contract price; and lower realized power prices in Canadian Power, partially offset by lower business development costs

•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 1.39 in 2025 versus 1.40 in 2024. 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.

Comparable earnings from continuing operations

Fourth quarter 2025 versus fourth quarter 2024

Comparable earnings decreased by $76 million or $0.07 per common share for the three months ended December 31, 2025 compared to the same period in 2024 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 income tax expense primarily due to the impact of Mexico foreign exchange exposure and higher flow-through income taxes

•higher depreciation and amortization primarily due to higher depreciation rates on the NGTL System under the 2025-2029 Revenue Requirement Settlement (2025-2029 NGTL Settlement) and from Columbia Gas as a result of the Columbia Gas Settlement. Refer to U.S. Natural Gas Pipelines - Significant events section in the MD&A of our 2025 Annual Report for additional information

•lower interest income and other due to an increase in insurance-related provisions and lower interest earned on short-term investments

•higher interest expense due to lower realized gains on derivatives used to manage our interest rate risk, increased levels of short-term borrowing and long-term debt issuances and maturities

•higher net income attributable to non-controlling interests is primarily the result of higher net income recognized from the Columbia Gas and Columbia Gulf assets, partially offset by the net effect of higher tax expense, higher EBITDA and lower AFUDC in TGNH following Southeast Gateway pipeline's completion in second quarter 2025 and the overall impact of foreign exchange

•risk management activities used to manage our foreign exchange exposure to net liabilities in Mexico and to         U.S. dollar-denominated income and the revaluation of our peso-denominated net monetary liabilities to U.S. dollars.

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

We expect our 2026 comparable EBITDA and our 2026 comparable earnings per common share to be higher than 2025 due to the net impact of the following:

•new projects anticipated to be placed in service in 2026, along with the full-year impact of projects placed in service in 2025

•higher revenue from the Columbia Gas settlement

•higher net generation from Bruce Power due to the return to service of Unit 3 from the MCR outage, partially offset by the commencement of the Unit 5 MCR outage

•higher depreciation due to the in-service of Canadian Natural Gas Pipelines and U.S. Natural Gas Pipelines projects

•lower AFUDC primarily due to Southeast Gateway pipeline in-service in 2025.

Consolidated capital expenditures

In 2025, we incurred approximately $5.9 billion in gross capital expenditures on our secured capital program and projects under development, as well as capitalized interest and AFUDC, where applicable. Net capital expenditures after adjusting for the capital expenditures attributable to the non-controlling interests of entities we control were approximately $5.3 billion.

Prior to adjustments for non-controlling interests, we expect to incur gross capital expenditures of approximately $6.0 to     $6.5 billion in 2026. We anticipate our net capital expenditures in 2026 to be approximately $5.5 to $6.0 billion.

The majority of our 2026 capital program is focused on the advancement of secured projects including U.S. Natural Gas Pipelines projects, NGTL System expansions, pipeline projects in Mexico, Bruce Power MCR programs and normal course maintenance capital expenditures.

Refer to the Outlook section in each business segment for additional details on expected earnings and capital expenditures
for 2026.

TC Energy Fourth Quarter News Release 2025 | 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 $21 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.

During 2025, we placed approximately $8.3 billion of projects into service, which included natural gas pipeline capacity projects along our extensive North American asset footprint, including the Southeast Gateway pipeline, as well as progress on the Bruce Power life extension program. In addition, approximately $2.2 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.

TC Energy Fourth Quarter News Release 2025 | 13

Projects under development

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. Projects under development have greater uncertainty with respect to timing and estimated project costs and are subject to company and regulatory approvals, unless otherwise noted. New growth opportunities will be assessed within our disciplined capital allocation framework in order to fit within our annual capital expenditure parameters. As these new opportunities advance and reach required milestones, they will be included in the Secured projects table.

Canadian Natural Gas Pipelines

We continue to focus on optimizing the utilization and value of our existing Canadian Natural Gas Pipelines assets, including sanctioned in-corridor expansions, providing connectivity to LNG export terminals, connecting growing WCSB gas supplies to domestic and export markets and other opportunities, including progressing our Multi-Year Growth Plan (MYGP). The MYGP is comprised of multiple distinct projects with various targeted in-service dates, subject to final company and regulatory approvals.

U.S. Natural Gas Pipelines

We are currently pursuing a variety of projects that are expected to replace, upgrade, expand and extend our U.S. Natural Gas Pipelines footprint. The enhanced facilities associated with these projects are expected to improve the reliability of our systems and provide additional transportation capacity under long-term contracts. We continue to see growing demand across multiple segments, driving potential expansion projects to support new natural gas-fired power generation, coal to natural gas conversions, LDC growth and data centres. Our footprint is well positioned to deliver natural gas supply through our existing utility customer base or by way of direct connections. Additional opportunities include direct and indirect interconnects to supply power to data centres, continued LNG development in proximity to our footprint and LDC peak day growth.

Power and Energy Solutions

Bruce Power

Life Extension Program

The continuation of Bruce Power’s life extension program will require the investment of our proportionate share of both the MCR program costs on Units 7 and 8 and the remaining Asset Management program costs, which continue beyond the completion of the MCR program in 2033, extending the life of Units 3 to 8 and the Bruce Power site to 2064. Preparation work for the Unit 7 and 8 MCRs is underway and future MCR investments will be subject to discrete decisions for each unit with specified off-ramps available to Bruce Power and the IESO.

Energy Solutions

Ontario Pumped Storage

With our prospective partners, Saugeen Ojibway Nation, we continue to advance the Ontario Pumped Storage Project, an energy storage facility located in Meaford, Ontario. The 1,000 MW project is expected to provide enough electricity to power one million homes for up to 11 hours, while enhancing the reliability and efficiency of Ontario's electricity system.

Using water and gravity, the project is like a natural battery that will store surplus electricity when demand is low and later redeploy it during periods of high demand. The project will support the planned buildout of Ontario’s nuclear fleet and can deliver Ontario’s clean nuclear power on demand.

In January 2025, the Ontario Government announced it was investing up to $285 million to advance pre-development work on the project. With this investment, the project is advancing critical development work, including the completion of a detailed cost estimate, the commencement of federal and provincial environmental assessments, advanced design and engineering and continued community engagement. It is expected that our Board of Directors, Saugeen Ojibway Nation and the Ontario Government will each make a final investment decision on the project following this pre-development work.

Canadian Natural Gas Pipelines segmented earnings increased by $58 million for the three months ended December 31, 2025 compared to the same period in 2024.

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.

Net income for the NGTL System increased by $17 million for the three months ended December 31, 2025 compared to the same period in 2024 primarily due to higher incentive earnings. The NGTL System is currently operating under the         CER-approved 2025-2029 NGTL Settlement which commenced on January 1, 2025 and 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.

TC Energy Fourth Quarter News Release 2025 | 15

Net income for the Canadian Mainline increased by $5 million for the three months ended December 31, 2025 compared to the same period in 2024 mainly due to higher incentive earnings. 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 $110 million for the three months ended December 31, 2025 compared to the same period in 2024 due to higher flow-through depreciation and income taxes as well as higher incentive earnings on the NGTL System and the Canadian Mainline.

DEPRECIATION AND AMORTIZATION

Depreciation and amortization increased by $52 million for the three months ended December 31, 2025 compared to the same period in 2024 primarily reflecting higher depreciation rates on the NGTL System under the 2025-2029 NGTL Settlement and an increase in assets placed in service on the Canadian Mainline.

U.S. Natural Gas Pipelines segmented earnings increased by $192 million for the three months ended December 31, 2025 compared to the same period in 2024 and included unrealized gains and losses from changes in the fair value of derivatives used in our U.S. natural gas marketing business which has been excluded from our calculation of comparable EBITDA and comparable EBIT.

A weaker U.S. dollar for the three months ended December 31, 2025 had a negative impact on the Canadian dollar equivalent segmented earnings from our U.S. dollar-denominated operations compared to the same period in 2024. 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.

TC Energy Fourth Quarter News Release 2025 | 17

Comparable EBITDA for U.S. Natural Gas Pipelines increased by US$137 million for the three months ended December 31, 2025 compared to the same period in 2024 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. Refer to the U.S. Natural Gas Pipelines - Significant events section in the MD&A of our 2025 Annual Report for additional information

•incremental earnings from projects placed in service, as well as increased earnings from additional contract sales on GTN

•higher realized earnings related to our U.S. natural gas marketing business primarily due to higher margins

•decreased earnings due to higher operational costs, reflective of increased system utilization across our footprint.

DEPRECIATION AND AMORTIZATION

Depreciation and amortization increased by US$19 million for the three months ended December 31, 2025 compared to the same period in 2024 primarily due to new projects placed in service and depreciation rate changes as a result of the Columbia Gas Settlement.

Mexico Natural Gas Pipelines segmented earnings increased by $163 million for the three months ended December 31, 2025 compared to the same period in 2024 and included a recovery of $4 million (2024 – recovery of $3 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 and year ended December 31, 2025 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 2024. Refer to the Foreign exchange section for additional information.

Comparable EBITDA for Mexico Natural Gas Pipelines increased by US$118 million for the three months ended December 31, 2025 compared with the same period in 2024, due to the net effect of:

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

•lower equity earnings from Sur de Texas primarily due to the foreign exchange impacts on the revaluation of
peso-denominated liabilities as a result of a stronger Mexican peso and higher income tax expense mainly related to the foreign exchange impacts of U.S. dollar-denominated liabilities.

DEPRECIATION AND AMORTIZATION

Depreciation and amortization was generally consistent for the three months ended December 31, 2025 compared to the same period in 2024. 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.

•a pre-tax impairment charge in 2025 of $110 million (2024 - $36 million) for certain Power and Energy Solutions projects following our decision to discontinue development along with updated forecast assumptions as we refocus our Power and Energy Solutions strategy

•our proportionate share of Bruce Power's unrealized gains and losses on funds invested for post-retirement benefits and risk management activities

•unrealized gains and losses from changes in the fair value of derivatives used to reduce commodity exposures.

Comparable EBITDA for Power and Energy Solutions decreased by $124 million for the three months ended December 31, 2025 compared to the same period in 2024 primarily due to the net effect of:

•lower Bruce Power contributions from reduced generation due to the Unit 4 MCR, planned Unit 2 outage in fourth quarter 2025 and increased operating costs, partially offset by a higher contract price. Refer to the Bruce Power results section for additional information

•decreased Canadian Power financial results primarily from lower realized power prices

•increased Natural Gas Storage and other is primarily due to lower business development costs.

Interest expense increased by $194 million for the three months ended December 31, 2025 compared to the same period in 2024. The following specific items have been removed from our calculation of interest expense included in comparable earnings:

•pre-tax net gain on debt extinguishment of $228 million was recorded related to the purchase and cancellation of certain senior unsecured notes and medium term notes and the retirement of outstanding callable notes in October 2024

•unrealized gains and losses on derivatives used to manage our interest rate risk.

Interest expense included in comparable earnings increased by $38 million for the three months ended December 31, 2025 compared to the same period in 2024 primarily due to the net effect of:

•lower realized gains on derivatives used to manage our interest rate risk

•increased levels of short-term borrowing

•long-term debt issuances and maturities. Refer to Corporate - Financial condition section in the MD&A of our 2025 Annual Report for additional information.

AFUDC decreased by $197 million for the three months ended December 31, 2025 compared to the same period in 2024. The decrease in U.S. dollar-denominated AFUDC is mainly the result of the completion of the Southeast Gateway pipeline in second quarter 2025 and the suspension of AFUDC on the south section of the Villa de Reyes pipeline in first quarter 2025 due to ongoing construction delays on the project pending the resolution of outstanding stakeholder issues and U.S natural gas pipeline projects placed in service in 2025 compared to 2024.

Foreign exchange gains (losses), net included in comparable earnings changed by $73 million for the three months ended December 31, 2025 compared to the same period in 2024. The changes were primarily due to the net effect of:

•risk management activities used to manage our foreign exchange exposure to net liabilities in Mexico and to U.S. dollar‑denominated income

•foreign exchange losses in 2025 compared to foreign exchange gains in 2024 on the revaluation of our peso-denominated net monetary liabilities to U.S. dollars.

TC Energy Fourth Quarter News Release 2025 | 25

Income tax expense included in comparable earnings increased by $98 million for the three months ended December 31, 2025 compared to the same period in 2024 primarily due to the impact of Mexico foreign exchange exposure and higher     flow-through income taxes, partially offset by a change in geographic and business mix of earnings.

Net income attributable to non-controlling interests decreased by $16 million for the three months ended December 31, 2025 compared to the same period in 2024 and included the following specific items which have been excluded from our calculation of Net (income) loss attributable to non-controlling interests included in comparable earnings:

•the non-controlling interest portion of the unrealized foreign exchange gains and losses on the TGNH peso-denominated intercompany loan payable to TCPL

•the expected credit loss provision related to the TGNH net investment in leases.

Net income attributable to non-controlling interests included in comparable earnings increased by $12 million for the three months ended December 31, 2025 compared to the same period in 2024 resulting from the net impact of higher net income recognized from the Columbia Gas and Columbia Gulf assets, partially offset by the net effect of higher tax expense, higher EBITDA and lower AFUDC in TGNH following Southeast Gateway pipeline's completion in second quarter 2025 and the overall impact of foreign exchange.

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 December 31, 2025 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.

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.

TC Energy Fourth Quarter News Release 2025 | 27

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 Other information – Financial risks and Financial instruments sections in the

MD&A of our 2025 Annual Report for additional information.

The period end exchange rates for one U.S. dollar to Mexican pesos were as follows:

December 31, 2024						20.87
December 31, 2023						16.91

Net cash provided by operations

Net cash provided by operations decreased by $190 million for the three months ended December 31, 2025 compared to the same period in 2024 primarily due to the timing of working capital changes, partially offset by 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 $628 million for the three months ended December 31, 2025 compared to the same period in 2024 primarily due to higher comparable EBITDA and higher distributions from our equity investments.
