**A.&nbsp;&nbsp;&nbsp;&nbsp;Audited Consolidated Financial Statements**

**UNDERTAKING**

Each Registrant undertakes to make available, in person or by telephone, representatives to respond to inquiries made by the Commission staff, and to furnish promptly, when requested to do so by the Commission staff, information relating to: the securities registered pursuant to Form 40-F; the securities in relation to which the obligation to file an annual report on Form 40-F arises; or transactions in said securities.

**CODE OF ETHICS**

The Registrants have adopted a code of business ethics ("Code") for their directors, officers, employees and contractors. In 2025, the Code was reviewed and amended to incorporate certain non-material and administrative changes. These changes did not alter the substantive principles or requirements of the Code.

The Registrants' Code is available on TC Energy's website at www.tcenergy.com and any person can obtain the Code without charge upon request from the Corporate Secretary of TC Energy. No waivers have been granted from any provision of the Code during the 2025 fiscal year.

You can read more about these factors and others in reports we have filed with Canadian securities regulators and the Commission.

As actual results could vary significantly from the forward-looking information, you should not put undue reliance on forward-looking information and should not use future-oriented information or financial outlooks for anything other than their intended purpose. We do not update our forward-looking statements due to new information or future events unless we are required to by law.

**NATURAL GAS PIPELINES**

**Developments in the Canadian Natural Gas Pipelines Segment** 

---

| |
|:---|
| **CANADIAN REGULATED PIPELINES** |
| **2021 NGTL System Expansion Program** |
| The 2021 NGTL System Expansion Program was completed in 2024 and consists of 344 km (214 miles) of new pipeline, three new compressor units and associated facilities and added approximately 1.59 PJ/d (1.45 Bcf/d) of incremental capacity to the NGTL System. The capital cost of the program was $3.6 billion. |
| **2022 NGTL System Expansion Program** |
| The 2022 NGTL System Expansion Program was completed in 2023 and consists of approximately 166 km (103 miles) of new pipeline, one compressor unit and associated facilities and provides incremental capacity of approximately 773 TJ/d (722 MMcf/d) to meet firm-receipt and intra-basin delivery requirements with eight-year minimum terms. The capital cost of the program was $1.4 billion. |
| **2023 NGTL System Intra-Basin Expansion** |
| The NGTL System Intra-Basin Expansion was completed in 2024 and consists of 23 km (14 miles) of new pipeline and two new compressor stations and is underpinned by approximately 255 TJ/d (238 MMcf/d) of new firm-service contracts with 15-year terms. The capital cost of the expansion was $0.5 billion. |
| **NGTL System/Foothills West Path Delivery Program** |
| The NGTL System/Foothills West Path Delivery Program was completed in 2023 and consisted of a multi-year expansion of the NGTL System and Foothills system to facilitate incremental contracted export capacity connecting to the GTN pipeline system. The combined NGTL System and Foothills program consists of approximately 107 km (66 miles) of pipeline and associated facilities and is underpinned by 275 TJ/d (258 MMcf/d) of new firm-service contracts with terms that exceed 30 years. The capital cost of the program was $1.6 billion. |
| **Valhalla North and Berland River Project**  |
| In November 2022, we sanctioned the Valhalla North and Berland River (VNBR) Project to serve aggregate system requirements and connect migrating supply to key demand markets, designed to provide incremental capacity on the NGTL System of approximately 428 TJ/d (400 MMcf/d). On December 21, 2023, we received approval from the CER to construct, own and operate the VNBR Project. 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 Berland River section, which includes a new non-emitting electric compressor unit and associated facilities, has a target in-service date in the second half of 2026 and an estimated capital cost of $0.3 billion. |
| **NGTL Ownership Transfer** |
| On April 1, 2024, ownership of the NGTL System was transferred from Nova Gas Transmission Ltd. to NGTL GP Ltd. on behalf of NGTL Limited Partnership as part of an ordinary course corporate reorganization to support business optimization.  |
| **NGTL System - Revenue Requirement Settlement and Multi-Year Growth Plan** |
| On September 26, 2024, the CER approved a five-year negotiated revenue requirement settlement commencing on January 1, 2025.<br>The 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 Multi-Year Growth Plan (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. To date, approximately $1.1 billion of MYGP expansion facilities have received FID, with various in-service dates starting in 2026. Completion of the MYGP is expected to enable approximately 1.0 Bcf/d of incremental system throughput.<br>The settlement maintains an ROE of 10.1 per cent on 40 per cent deemed common equity while increasing NGTL System depreciation rates, with an incentive that allows the NGTL System the opportunity to further increase depreciation rates if tolls fall below specified levels, or if growth projects are undertaken. The settlement introduces a new incentive mechanism to reduce both physical emissions and emissions compliance costs, which builds on the incentive mechanism for certain operating costs where variances from projected amounts and emissions savings are shared with our customers. A provision for review by customers exists in the settlement if tolls exceed a pre-determined level or if final company approvals of the multi-year growth plan are not obtained. |

| **LNG PIPELINE PROJECTS** |
| **Coastal GasLink Pipeline** |
| The Coastal GasLink pipeline is a 671 km (417 mile) pipeline that transports natural gas from a receipt point in the Dawson Creek area of British Columbia to LNG Canada's (LNGC) natural gas liquefaction facility near Kitimat, British Columbia. Transportation service on the pipeline is underpinned by 25-year TSAs (with renewal provisions) with each of the five LNGC joint venture participants (LNGC Participants). We hold a 35 per cent ownership interest in Coastal GasLink Limited Partnership (CGL LP), the entity that owns the Coastal GasLink pipeline. Additionally, we hold a 100 percent ownership interest in the general partner of CGL LP, the entity that operates the pipeline.<br>Throughout construction, the project faced material cost pressures driven by the pandemic, labour, contractor and weather challenges, which ultimately increased the estimated cost of the project to approximately $14.5 billion, excluding potential cost recoveries and after accounting for certain factors that may be outside the control of CGL LP. In connection with the revised cost estimate, we announced our expectation that additional equity contributions required to fund the incremental project costs would be predominantly funded by us, with our share of total equity contributions expected to be up to $5.5 billion and no anticipated change to our 35 per cent ownership interest. This expectation resulted in the recording of cumulative pre-tax impairment charges of $5,148 million ($4,586 million after tax) between December 2022 and September 2023. No further impairment charges have been recorded since September 2023.<br>In 2023, the Coastal GasLink pipeline project achieved mechanical completion, completed pipeline commissioning activities and was ready to deliver gas to the LNGC facility. These milestones entitled CGL LP to receive a $200 million readiness incentive payment from LNGC. The payment, which accrued entirely to TC Energy under the contractual terms between the CGL LP partners, was recognized as revenue by TC Energy in December 2023 and was received in February 2024.<br>In June 2024, CGL LP successfully completed a $7.15 billion refinancing of its existing construction credit facility through a private placement bond offering of senior secured notes to Canadian and U.S. investors. Proceeds from the offering were used to repay the majority of the outstanding $8.0 billion balance on CGL LP's construction credit facility. The remaining balance on the construction credit facility was settled through the use of proceeds from the unwinding of certain hedging arrangements associated with the construction credit facility.<br>In November 2024, CGL LP executed a commercial agreement with LNGC and each of the five LNGC Participants that retroactively declared commercial in-service for the Coastal GasLink pipeline effective October 1, 2024, and provided for a one-time payment of $199 million from LNGC Participants to TC Energy in recognition of completed work and final cost settlement. The payment, which accrued entirely to TC Energy under the contractual arrangements between the CGL LP partners, was recognized as an in-substance distribution from CGL LP in 2024 and was received in October 2025.<br>In December 2024, following the commercial in-service of the Coastal GasLink pipeline, CGL LP repaid the $3,147 million balance owing under its subordinated loan agreement with TC Energy. Our share of equity contributions required by CGL LP to fund repayment of the subordinated loan amounted to $3,137 million. <br>At December 31, 2025, our share of total partner equity contributions to fund the capital cost of the project was $5.3 billion. Reclamation activities associated with post-construction work were completed in 2025. In addition, CGL LP has resolved all material claims with a net positive recovery overall to CGL LP. Unused capacity of $163 million remains available under the subordinated loan agreement with TC Energy, though it is not anticipated that CGL LP will draw on a significant portion of the remaining availability.  |
| **Coastal GasLink - Cedar Link Expansion** |
| In June 2024, CGL LP sanctioned the Cedar Link project following a positive FID for the construction of the Cedar LNG facility by the Cedar LNG joint venture partners, Haisla Nation and Pembina Pipeline Corporation. The Cedar LNG facility is a proposed floating liquefied natural gas facility to be constructed in Kitimat, British Columbia. The Cedar Link project is an expansion of the Coastal GasLink pipeline that is expected to enable delivery of up to 0.4 Bcf/d of natural gas to the Cedar LNG facility. With an estimated cost of $1.2 billion at FID, the expansion project includes the addition of a new compressor station, connector pipeline and meter station to the existing Coastal GasLink pipeline infrastructure. <br>Funding for the expansion will be provided through project-level credit facilities of up to $1.4 billion secured by CGL LP in June 2024, equity funding to be provided by the CGL LP partners, including us, and the recovery of construction carrying costs from LNGC Participants who have elected to make payments on a quarterly basis throughout construction. The incremental funds available through the project-level credit facilities and cash AFUDC payments provide additional contingency to mitigate future funding requirements for CGL LP should costs exceed initial estimates of $1.2 billion. TC Energy has entered into an equity contribution agreement to fund up to a maximum of $37 million for its proportionate share of the equity requirements related to the Cedar Link project.<br>All major regulatory permits have been received and construction began in July 2024. The planned in-service date for the Cedar Link project is 2028, subject to the completion of plant commissioning activities at the Cedar LNG facility. |
| **Coastal GasLink - Indigenous Equity Option** |
| In March 2022, we announced the signing of option agreements to sell up to a 10 per cent equity interest in CGL LP, to Indigenous communities across the project corridor, from our current 35 per cent equity ownership. In January 2026, prospective investors entered into a binding window for these options, which is expected to remain in effect through the end of 2026. Closing of the equity sale is subject to customary regulatory approvals and consents, including the consent of LNGC.  |

| **U.S. NATURAL GAS PIPELINES - COLUMBIA PIPELINE GROUP** |
| **Columbia Gas and Columbia Gulf Monetization** |
| On October 4, 2023, we completed the sale of a 40 per cent equity interest in Columbia Gas and Columbia Gulf to Global Infrastructure Partners (GIP) for proceeds of $5.3 billion (US$3.9 billion). Columbia Gas and Columbia Gulf are held by a newly formed entity with GIP. Preceding the close of the equity sale, on August 8, 2023, Columbia Pipelines Operating Company LLC and Columbia Pipelines Holding Company LLC issued US$4.6 billion and US$1.0 billion of long-term, senior unsecured debt, respectively.

**HEALTH, SAFETY, SUSTAINABILITY AND ENVIRONMENTAL PROTECTION GOVERNANCE AND SOCIAL POLICIES** 

A discussion of our health, safety, sustainability and environmental protection governance can be found in the MD&A in the *Other information – Health, safety, sustainability and environmental matters* section, which section is incorporated by reference herein.

**Social Policies**

We have a number of corporate governance documents, such as policies and standards, including a Commitment Statement, <br>to help guide our teams' behavior and actions with respect to our core values as well as legal and compliance obligations so they understand their responsibilities and extend respect and courtesy to Indigenous groups and other stakeholders. We have a Code of Business Ethics (COBE) Policy which functions together with TC Energy's other policies and applies to all employees, officers and directors, and contingent workforce contractors of TC Energy and its wholly-owned subsidiaries and/or operated entities <br>in all countries where we conduct business, with the exception of independently operated entities whose corporate governance documents meet or exceed TC Energy's requirements. Annual online COBE training is provided to all employees and contingent workforce contractors, and all employees and contingent workforce contractors (including executive officers) and directors must certify their compliance with COBE annually. In addition, TC Energy has a Contractor COBE Policy which imposes the same requirements as the COBE Policy on Contractors, as applicable.

We also have an Avoiding Bribery and Corruption (ABC) Program which includes an ABC Policy, annual online training included <br>as part of annual online COBE training, instructor-led training provided to personnel in higher risk locations of our business, <br>a supplier and contractor due diligence review process, and auditing of certain types of transactions.

Our Indigenous Relations Policy is informed by our guiding principles and core values to ensure we build and sustain support through early and honest communication, by mitigating impacts, and through mutually beneficial partnerships. We seek <br>to listen to Indigenous peoples and incorporate their traditional and local knowledge in project design and planning. We strive <br>to work with Indigenous communities to mitigate negative impacts and maximize benefits through hiring and buying locally. <br>We aim to build mutually beneficial, partnership-oriented relationships with Indigenous communities who are most impacted <br>by our activities. In Canada, we will seek to expand benefits for equity participation in our projects because the best way to align interests from the start is to sit at the table together as partners/owners. Through all these efforts, we strive to be considered <br>as a partner of choice for Indigenous groups and play a meaningful role in reconciliation.

Consistent with our four core values, *safety in every step, personal accountability, one team* and *active learning*, Commitment Statement and as outlined in our COBE Policy, TC Energy does not tolerate human rights abuses. In our business activities, including engaging with Indigenous groups and other stakeholders across Canada, the U.S and Mexico, we are committed <br>to respecting human rights and will not be complicit with, or engage in, any activity that supports or facilitates abuse of <br>human rights such as forced labour, child labour, or physical or mental abuses.

Risk factors

A discussion of our risk factors can be found in the MD&A in the *Natural Gas Pipelines Business, Natural Gas Pipelines - Business risks, Power and Energy Solutions – Business risks* and *Other information – Risk oversight and enterprise risk management* sections, which sections are incorporated by reference herein.

Dividends

Our Board has not adopted a formal dividend policy. The Board reviews the financial performance of TC Energy quarterly and makes a determination of the appropriate level of dividends to be declared in the following quarter. Currently, our payment of dividends is primarily funded from dividends TC Energy receives as the sole common shareholder of TCPL.

Provisions of various trust indentures and credit arrangements with certain of our subsidiaries can restrict those subsidiaries' ability and, in certain cases, our ability to declare and pay dividends or make distributions under certain circumstances. In the opinion of management, these provisions do not currently restrict our ability to declare or pay dividends.

Additionally, the terms of the hybrid notes issued by TCPL and trust notes issued by TransCanada Trust (a financing trust subsidiary wholly-owned by TCPL), and the respective related agreements, contain dividend stopper provisions which, among other things, are generally triggered if TCPL elects to defer interest payable on the applicable notes. When such provisions are triggered, they prohibit TC Energy and TCPL from declaring or paying dividends, among other prohibitive measures. The dividend stopper provisions have not been triggered for either the hybrid notes or the trust notes.

Dividends on our preferred shares are payable quarterly, as and when declared by the Board. The dividends declared on our common and preferred shares during the past three completed financial years, and the quarterly dividend per common share <br>on our outstanding common shares for the quarter ending March 31, 2026, are set out in the MD&A under the heading <br>*About our business – 2025 Financial highlights – Dividends* section, which section is incorporated by reference herein.

Description of capital structure

**SHARE CAPITAL**

TC Energy's authorized share capital consists of an unlimited number of common shares and an unlimited number of first preferred shares and second preferred shares, issuable in series. The number of common shares and preferred shares issued and outstanding as at Year End are set out in the MD&A in the *Financial Condition – Share information* section, which section is incorporated by reference herein. The following is a description of the material characteristics of each of these classes of shares.

**Common shares**

The common shares entitle the holders thereof to one vote per share at all meetings of shareholders, except meetings at which only holders of another specified class of shares are entitled to vote, and, subject to the rights, privileges, restrictions and conditions attaching to the first preferred shares and the second preferred shares, whether as a class or a series, and to any other class or series of shares of TC Energy which rank prior to the common shares, entitle the holders thereof to receive (i) dividends if, as and when declared by the Board out of the assets of TC Energy properly applicable to the payment of the dividends in such amount and payable at such times and at such place or places as the Board may from time to time determine, and (ii) the remaining property of TC Energy upon a liquidation, dissolution or winding up of the Company.

We have a shareholder rights plan (the Plan) that is designed to protect the rights of our shareholders, ensure they are treated fairly and provide the Board with adequate time to identify, develop and negotiate alternative value maximizing transactions if there is a take-over bid for TC Energy. The Plan creates a right attaching to each common share outstanding and to each common share subsequently issued. Each right becomes exercisable 10 trading days after a person has acquired (an acquiring person), or commences a take-over bid to acquire, 20 per cent or more of the common shares, other than by an acquisition pursuant to a take-over bid permitted under the terms of the Plan (a permitted bid). Prior to a flip-in event (as described below), each right permits registered holders to purchase from the Company common shares of TC Energy at an exercise price equal to three times the market price of such shares, subject to adjustments and anti-dilution provisions (the exercise price). The beneficial acquisition by any person of 20 per cent or more of the common shares, other than by way of a permitted bid, is referred to as a flip-in event. Ten trading days after a flip-in event, each right will permit registered holders other than an acquiring person to receive, upon payment of the exercise price, the number of common shares with an aggregate market price equal to twice the exercise price. The Plan was reconfirmed at the 2025 annual meeting of TC Energy shareholders and must be reconfirmed at every third annual meeting thereafter.

A discussion of our dividend reinvestment and share purchase plan can be found in the MD&A in the *About our business* - *2025 Financial highlights* – *Dividends* – *Dividend reinvestment and share purchase plan* and the *Financial condition* - *Dividend reinvestment plan* sections, which sections are incorporated by reference herein.

**First preferred shares**

Subject to certain limitations, the Board may, from time to time, issue first preferred shares in one or more series and determine for any such series, its designation, number of shares and respective rights, privileges, restrictions and conditions. The first preferred shares as a class have, among others, the provisions described below.

The first preferred shares of each series rank on a parity with the first preferred shares of every other series, and are entitled <br>to preference over the common shares, the second preferred shares and any other shares ranking junior to the first preferred shares with respect to the payment of dividends, the repayment of capital and the distribution of assets of TC Energy in the event of its liquidation, dissolution or winding up.

Except as provided by the CBCA, the holders of the first preferred shares will not have any voting rights nor will they be entitled to receive notice of or to attend shareholders' meetings. The holders of any particular series of first preferred shares will, if the directors so determine prior to the issuance of such series, be entitled to such voting rights as may be determined by the Board <br>if TC Energy fails to pay dividends on that series of preferred shares for any period as may be so determined by the Board. <br>TC Energy currently does not intend to issue any first preferred shares with voting rights, and any issuances of first preferred shares are expected to be made only in connection with corporate financings.

The provisions attaching to the first preferred shares as a class may be modified, amended or varied only with the approval <br>of the holders of the first preferred shares as a class. Any such approval to be given by the holders of the first preferred shares may be given by the affirmative vote of the holders of not less than 66 <sup>2/3</sup> per cent of the first preferred shares represented <br>and voted at a meeting or adjourned meeting of such holders.

The holders of Series 1, 3, 5, 7 and 9 preferred shares will be entitled to receive quarterly fixed rate cumulative preferential cash dividends, as and when declared by the Board, to be reset periodically on prescribed dates to an annualized rate equal to the sum of the then five-year Government of Canada bond yield, calculated at the start of the applicable five-year period, and a spread as set forth in the table below and have the right to convert their shares into cumulative redeemable Series 2, 4, 6, 8 <br>and 10 preferred shares, respectively, subject to certain conditions, on such conversion dates as set forth in the table below. <br>The Series 1, 3, 5, 7 and 9 preferred shares are redeemable by TC Energy in whole or in part on such redemption dates as set forth in the table below, by the payment of an amount in cash for each share to be redeemed equal to $25.00 plus all accrued and unpaid dividends thereon.

The holders of Series 2, 4, 6, 8 and 10 preferred shares will be entitled to receive quarterly floating rate cumulative preferential cash dividends, as and when declared by the Board, at an annualized rate equal to the sum of the then 90-day Government of Canada treasury bill rate, recalculated quarterly, and a spread as set forth in the table below and have the right to convert their shares into Series 1, 3, 5, 7 and 9 preferred shares, respectively, subject to certain conditions, on such conversion dates as set forth in the table below. The Series 2, 4, 6, 8 and 10 preferred shares are redeemable by TC Energy in whole or in part after their respective initial redemption date as set forth in the table below, by the payment of an amount in cash for each share to be redeemed equal to (i) $25.00 in the case of redemptions on such redemption dates as set out in the table below, or (ii) $25.50 <br>in the case of redemptions on any other date, in each case plus all accrued and unpaid dividends thereon.

Credit ratings

Although TC Energy has not issued debt to the public, it has been assigned credit ratings by Moody's Investors Service, Inc. (Moody's), S&P Global Ratings (S&P) and Fitch Ratings Inc. (Fitch), and its outstanding preferred shares have also been assigned credit ratings by S&P, Fitch and DBRS Limited (DBRS). Moody's has assigned TC Energy an issuer rating of Baa3 with a stable outlook, S&P has assigned an issuer credit rating of BBB+ with a stable outlook, and Fitch has assigned a long-term issuer default rating of BBB+ with a stable outlook. TC Energy does not presently intend to issue debt securities to the public in its own name and any future debt financing requirements are expected to continue to be funded primarily through its subsidiary, TCPL. <br>The following table sets out the current credit ratings assigned to those outstanding classes of securities of the Company, <br>TCPL and TransCanada Trust, and certain related subsidiaries which have been rated by Moody's, S&P, Fitch and DBRS:

---

Credit ratings are intended to provide investors with an independent measure of credit quality of an issue of securities. <br>Credit ratings are not recommendations to purchase, hold or sell securities and do not address the market price or suitability <br>of a specific security for a particular investor. There is no assurance that any rating will remain in effect for any given period <br>of time or that any rating will not be revised or withdrawn entirely by a rating agency in the future if, in its judgment, circumstances so warrant.

Each of the Company, TCPL, TransCanada Trust and certain of our other subsidiaries paid fees to each of Moody's, S&P, Fitch <br>and DBRS for the credit ratings rendered in respect of their outstanding classes of securities noted above. In addition to annual monitoring fees for the Company and TCPL and their rated securities, additional payments are made in respect of other services provided in connection with various rating advisory services.

The information concerning our credit ratings relates to our financing costs, liquidity and operations. The availability and cost <br>of our funding options may be affected by certain factors, including the global capital markets environment and outlook as well as our financial performance. Our access to capital markets for required capital at competitive rates is influenced by our credit rating and rating outlook, as determined by credit rating agencies such as Moody's, S&P, Fitch and DBRS. If our ratings were downgraded, TC Energy's financing costs and future debt issuances could be unfavourably impacted. A description of the rating agencies' credit ratings listed in the table above is set out below.

**MOODY'S**

Moody's has different rating scales for short- and long-term obligations. Numerical modifiers 1, 2 and 3 are appended to each rating classification from Aa through Caa. The modifier 1 indicates that the obligation ranks in the higher end of its generic rating category; the modifier 2 indicates a mid-range ranking; and a modifier 3 indicates a ranking in the lower end of that generic rating category. The Baa2 rating assigned to TCPL's senior unsecured debt and the Baa3 rating assigned to TCPL's junior subordinated notes are in the fourth highest of nine rating categories for long-term obligations. Obligations rated Baa are judged to be medium-grade and are subject to moderate credit risk, and as such, may possess certain speculative characteristics. The Ba1 rating assigned to the TransCanada Trust subordinated trust notes, is in the fifth highest of nine rating categories for long-term obligations. Obligations rated Ba are judged to have speculative elements and are subject to substantial credit risk. The P-2 rating assigned to TCPL's and TCPL guaranteed U.S. commercial paper programs is the second highest of four rating categories for short-term debt issuers. Issuers rated P-2 have a strong ability to repay short-term debt obligations. Outlooks may be assigned at the issuer level or at the rating level. A Moody's rating outlook is an opinion regarding the likely rating direction over the medium term. A stable outlook indicates a low likelihood of a rating change over the medium term. A negative, positive or developing outlook indicates a higher likelihood of a rating change over the medium term.

<sup>1</sup> The assigned rating applies to only certain classes of the securities noted, further details are set out below.

**S&P** 

S&P has different rating scales for short- and long-term obligations and Canadian preferred shares. Ratings from AA through CCC may be modified by the addition of a plus (+) or minus (-) sign to show the relative standing within a particular rating category. The BBB+ rating assigned to TCPL's senior unsecured debt is in the fourth highest of 10 rating categories for long-term obligations. A BBB rating indicates the obligor's capacity to meet its financial commitment is adequate; however, adverse economic conditions or changing circumstances are more likely to weaken the obligor's capacity to meet its financial commitments on the obligation. The BBB- ratings assigned to TCPL's junior subordinated notes and to the TransCanada Trust subordinated trust notes, is in the fourth highest of 10 rating categories for long-term debt obligations and the P-2 (Low) rating assigned to TC Energy's preferred shares is the second highest of eight rating categories for Canadian preferred shares. The BBB- ratings assigned to TCPL's junior subordinated notes and the TransCanada Trust subordinated trust notes, and the P-2 (Low) rating assigned to TC Energy's preferred shares indicate these obligations exhibit adequate protection parameters. However, adverse economic conditions or changing circumstances are more likely to weaken the obligor's capacity to meet its financial commitment on the obligation. TCPL's and TCPL guaranteed U.S. commercial paper programs are each rated A-2 which is the second highest of six rating categories for short-term debt issuers. Short-term debt issuers rated A-2 have satisfactory capacity to meet their financial commitments, however they are somewhat more susceptible to adverse effects of changes in circumstances and economic conditions than obligors in the highest rating category. S&P assigns outlooks to issuers and not to individual debt securities. An S&P outlook assesses the potential direction of a long-term credit rating over the intermediate term, which is generally up to two years for investment grade issuers. S&P has assigned a stable outlook to the Company, indicating its ratings are not likely to change over the intermediate term.

**FITCH**

Fitch has different rating scales for short- and long-term obligations. Ratings from AA through CCC may be modified by the addition of a plus (+) or minus (-) sign to show the relative status within a particular rating category. The BBB+ rating assigned <br>to TCPL's senior unsecured debt, and the BBB- ratings assigned to all series of TCPL's junior subordinated notes, with the exception of the series due 2067 which are not rated by Fitch, the TransCanada Trust subordinated trust notes and TC Energy's preferred shares are in the fourth highest of 11 rating categories for long-term obligations. A BBB rating indicates that expectations of default risk are currently low and that the capacity for payment of financial commitments is considered adequate, but adverse business or economic conditions are more likely to impair this capacity. The F2 rating assigned to TCPL's and TCPL guaranteed U.S. commercial paper program is the second highest of seven rating categories for short-term debt issuers. Issuers rated F2 have good intrinsic capacity for timely payment of financial commitments. Ratings outlooks by Fitch indicate the direction a rating is likely to move over a one-to-two year period and reflect financial or other trends that have <br>not yet reached or been sustained to the level that would cause a rating action, but which may do so if such trends continue.

**DBRS**

DBRS has different rating scales for short- and long-term obligations and Canadian preferred shares. High or low grades are used to indicate the relative standing within all rating categories other than AAA and D and other than in respect of DBRS' ratings <br>of commercial paper and short-term debt, which utilize high, middle and low subcategories for its R-1 and R-2 rating categories. <br>In respect of long-term debt and preferred share ratings, the absence of either a high or low designation indicates the rating <br>is in the middle of the category. The BBB (high) rating assigned to TCPL's senior unsecured debt and the BBB (low) rating assigned to TCPL's junior subordinated notes due 2067 are in the fourth highest of 10 categories for long-term debt and indicate adequate credit quality. The capacity for the payment of financial obligations is considered acceptable. Long-term debt rated BBB may be vulnerable to future events. The Pfd-3 (high) rating assigned to TC Energy's preferred shares is in the third highest <br>of six rating categories for preferred shares. Preferred shares rated Pfd-3 are generally of adequate credit quality. While protection of dividends and principal is still considered acceptable, the issuing entity is more susceptible to adverse changes <br>in financial and economic conditions, and there may be other adverse conditions present which detract from debt protection. Pfd-3 ratings generally correspond with issuers with a BBB category or higher reference point. The R-2 (high) rating assigned <br>to TCPL's Canadian commercial paper program is in the fourth highest of 10 rating categories for short-term debt issuers and indicates the upper end of adequate credit quality. The capacity for payment of short-term financial obligations as they fall due is acceptable. Short-term debt rated R-2 (high) may be vulnerable to future events. Rating trends provide guidance in respect <br>of DBRS' opinion regarding the outlook for a credit rating. The rating trend indicates the direction in which DBRS considers the credit rating may move if present circumstances continue.

As of the date hereof, except as indicated below, no other director or executive officer of the Company is or was a director <br>or officer of another company in the past 10 years that:

• was the subject of a cease trade or similar order, or an order denying that company access to any exemption under securities legislation, that was in effect for a period of more than 30 consecutive days

• was involved in an event that resulted in the company being subject to one of the above orders after the director or executive officer no longer held that role with the company, which resulted from an event that occurred while that person was acting <br>in the capacity as director, chief executive officer or chief financial officer

• while acting in that capacity, or within a year of ceasing to act in that capacity, became bankrupt, made a proposal under any legislation relating to bankruptcy or insolvency or was subject to or instituted any proceedings, arrangement or compromise with creditors or had a receiver, receiver manager or trustee appointed to hold the assets of that company.

In January 2019, PGE filed for bankruptcy under Chapter 11 of the United States Bankruptcy Code as a result of claims arising from fires caused by PGE's electrical equipment. Following discussions initiated by the PGE board of directors, Mr. Johnson agreed to serve as President and CEO throughout PGE's bankruptcy process, beginning May 2, 2019, with the understanding that upon PGE's emergence from bankruptcy he would resign from PGE. On July 1, 2020, PGE emerged from Chapter 11 bankruptcy, upon completing a restructuring process that was confirmed by the United States Bankruptcy Court on June 20, 2020. Mr. Johnson resigned as President and CEO of PGE on June 30, 2020.

Ms. Campbell joined the board of directors of PGE in April 2019, after PGE filed for bankruptcy under Chapter 11 of the United States Bankruptcy Code in January 2019 and prior to its emergence from Chapter 11 bankruptcy in July 2020. Ms. Campbell continues to be a director of PGE.

**CONFLICTS OF INTEREST** 

Directors and officers of TC Energy and its subsidiaries are required to disclose any existing or potential conflicts in accordance with TC Energy's policies governing directors and officers and in accordance with the CBCA.

COBE covers potential conflicts of interest and requires that all employees, officers, directors and contract workers of TC Energy avoid situations that may result in a potential conflict.

In the event an employee, officer, director or contract worker finds themselves in a potential conflict situation, COBE stipulates that:

• the conflict should be reported; and

• the person should refrain from participation in any decision or action where there is a real or perceived conflict.

COBE also notes that employees and officers of TC Energy may not engage in outside business activities that are in conflict <br>with or detrimental to the interests of TC Energy. The CEO and the executive leadership team must receive consent from <br>the Chair of the Governance Committee for all outside business activities.

Under COBE, directors must also declare any material interest that they may have in a material contract or transaction <br>and recuse themselves from related deliberations and approvals.

In addition to COBE, the directors and corporate officers of TC Energy are required to disclose any related parties and related party transactions in their annual directors and officers questionnaires. These questionnaires assist TC Energy in identifying <br>and monitoring material related party transactions.

The Governance Committee reviews and approves any material related party transactions prior to the transaction occurring, <br>and maintains oversight over material related party transactions following such approval.

There were no material conflicts of interests or related party transactions reported by the Board, CEO or the corporate officers, including the executive leadership team, in 2025.

TC Energy **Annual Information Form 2025** \| 29

------

**Serving on other boards**

The Board believes that it is important for it to be composed of qualified and knowledgeable directors. As a result, due to <br>the specialized nature of the energy infrastructure business, some of the directors are associated with or sit on the boards <br>of companies that ship natural gas through our pipeline systems. Transmission services on most of TC Energy's pipeline systems in Canada and the U.S. are subject to regulation and, accordingly, we generally cannot deny transportation services to a creditworthy shipper. The Governance Committee monitors relationships among directors to ensure that business associations do not affect the Board's performance.

The Board considers whether directors serving on the boards of, or acting as officers or in another similar capacity, for other entities including public and private companies, Crown corporations and other state-owned entities, and non-profit organizations pose any potential conflict. The Board reviews these relationships annually to determine that they do not interfere with any of our director's ability to act in our best interests. If a director declares a material interest in any material contract <br>or material transaction being considered at a meeting, the director is not present during the discussion and does not vote <br>on the matter.

COBE requires employees to receive consent before accepting a directorship with an entity that is not an affiliate. The CEO <br>and executive vice-presidents must receive the consent of the Chair of the Governance Committee. All other employees must receive the consent of the Corporate Secretary or their delegate.

**Affiliates**

The Board oversees relationships between TC Energy and any affiliates to avoid any potential conflicts of interest.

Corporate governance

Our Board and management are committed to the highest standards of ethical conduct and corporate governance.

TC Energy is a public company listed on the TSX and the NYSE, and we recognize and respect rules and regulations in both Canada and the U.S.

Our corporate governance practices comply with the Canadian governance guidelines, which include the governance rules <br>of the CBCA, TSX and Canadian Securities Administrators, including:

• National Instrument 52-110, *Audit Committees,*

• National Policy 58-201, *Corporate Governance Guidelines*, and

• National Instrument 58-101, *Disclosure of Corporate Governance Practices*.

We also comply with the governance listing standards of the NYSE and the governance rules of the SEC that apply, in each case, to foreign private issuers.

Our governance practices comply with the NYSE standards for U.S. companies in all significant respects. As a non-U.S. company, we are not required to comply with most of the governance listing standards of the NYSE. As a foreign private issuer, however, we must disclose how our governance practices differ from those followed by U.S. companies that are subject to the NYSE standards. Our corporate governance practices do not significantly differ from those required to be followed by U.S. domestic issuers under the NYSE's listing standards. A summary of our governance practices compared to U.S. standards can be found on our website (www.tcenergy.com).

We benchmark our policies and procedures against major North American companies to assess our standards and we adopt best practices as appropriate. Some of our best practices are derived from the NYSE rules and comply with applicable rules adopted <br>by the SEC to meet the requirements of the *Sarbanes-Oxley Act of 2002* and the *Dodd-Frank Wall Street Reform and Consumer Protection Act.*

**XII.&nbsp;&nbsp;&nbsp;&nbsp;Oversight Function**

While the Audit Committee has the responsibilities and powers set forth in this Charter, it is not the duty of the Audit Committee to plan or conduct audits or to determine that the Company's financial statements and disclosures are complete and accurate or are in accordance with generally accepted accounting principles and applicable rules and regulations. These are the responsibilities of management and the external auditor. The Audit Committee, its Chair and any of its members who have accounting or related financial management experience or expertise, are members of the Board, appointed to the Audit Committee to provide broad oversight of the financial disclosure, financial risk and control related activities of the Company, and are specifically not accountable nor responsible for the day to day operation of such activities. Although designation of a member or members as an "audit committee financial expert" is based on that individual's education and experience, which that individual will bring to bear in carrying out his or her duties on the Audit Committee, designation as an "audit committee financial expert" does not impose on such person any duties, obligations or liability that are greater than the duties, obligations and liability imposed on such person as a member of the Audit Committee and Board in the absence of such designation. Rather, the role of any audit committee financial expert, like the role of all Audit Committee members, is to oversee the process and not to certify or guarantee the internal or external audit of the Company's financial information or public disclosure.

**3.&nbsp;&nbsp;&nbsp;&nbsp;COMPOSITION OF AUDIT COMMITTEE**

The Audit Committee shall consist of three or more directors, a majority of whom are resident Canadians (as defined in the *Canada Business Corporations Act*), and all of whom are unrelated and/or independent for the purposes of applicable Canadian and United States securities law and applicable rules of any stock exchange on which the Company's securities are listed. Each member of the Audit Committee shall be financially literate and at least one member shall have accounting or related financial management expertise (as those terms are defined from time to time under the requirements or guidelines for audit committee service under securities laws and the applicable rules of any stock exchange on which the Company's securities are listed for trading or, if it is not so defined, as that term is interpreted by the Board in its business judgment).

**4.&nbsp;&nbsp;&nbsp;&nbsp;APPOINTMENT OF AUDIT COMMITTEE MEMBERS**

The members of the Audit Committee shall be appointed by the Board from time to time on the recommendation of the Governance Committee and shall hold office until the next annual meeting of shareholders or until their successors are earlier appointed or until they cease to be directors of the Company.

**OUR STRATEGY**

Our vision is to be the trusted leader in North America's energy infrastructure, committed to excellence in safety, performance and stakeholder relationships. Our mission is to safely and efficiently move, generate and store the critical energy that North America and the world rely on. Our value proposition: to deliver solid growth with low risk and repeatable performance, year after year.

Our business consists of natural gas transportation and storage, as well as power generation assets:

• we deliver natural gas to Canada, the U.S. and Mexico, including to export terminals that ship LNG globally

• we generate electricity in Canada and the U.S., primarily from nuclear energy, but also from natural gas, wind and solar assets

• we store natural gas in Canada and the U.S. through regulated and non-regulated businesses.

These long-life infrastructure assets are anchored by our conservative risk preferences and are generally supported by long-term commercial arrangements and/or rate regulation. We believe that our assets will generate predictable and sustainable cash flows and earnings, providing the cornerstones of our low-risk value proposition. Our long-term strategy is driven by the following key beliefs:

• natural gas will continue to play a pivotal role in North America's energy future and support global GHG emissions reduction

• the need for reliable, on-demand energy sources will continue to grow

• energy assets will become increasingly valuable in a world with growing energy demand and existing challenges in developing new infrastructure.

2&nbsp;&nbsp;&nbsp;&nbsp;Excludes losses from Corporate comparable EBITDA from continuing operations of $14 million and $63 million for the years ended December 31, 2025 and 2024, respectively.

Our asset mix will continue to evolve with the North American energy mix. We anticipate the following trends in capital allocation over the next several years:

• Natural Gas Pipelines will continue to attract capital to meet growing customer demand, driven by coal-to-gas conversion, LNG exports and data centre buildouts

• Power and Energy Solutions' capital will primarily be allocated to extending the life and increasing the capacity of the nuclear business. We will make measured investment in emerging technologies to develop capabilities that are complementary to our Natural Gas Pipelines business, without taking significant commodity price risk, volumetric risk or utilizing unproven technologies

• additional discretionary investment will fund select high-grade opportunities in our development projects portfolio and incremental opportunities around existing assets across our businesses.

------

**Key components of our strategy** 

**Maximize the value of our assets through safety and operational excellence**

Maintaining safe and reliable operations by maximizing asset availability and integrity while minimizing environmental impacts remains the foundation of our business. Our extensive natural gas pipeline network connects long-life, low-cost supply basins with premium North American and export markets, generating predictable and sustainable cash flows and earnings, while our power and non-regulated storage assets, primarily under long-term contracts, provide stable returns. We continually seek to enhance and protect asset value through operational, commercial and marketing initiatives.

**Execute our selective portfolio of growth projects**

Safety, executability, profitability, and reliability are fundamental to our investments, which focus on developing high-quality, long-life assets largely underpinned by long-term contracts or rate regulation. Leveraging our incumbent positions in regions with growing natural gas and power demand, we manage costs and construction risk in a disciplined manner to maximize capital efficiency and shareholder returns. We also look to advance select lower-carbon growth initiatives in emerging sub-sectors where technology is proven, risks and returns are acceptable and we can build a strong competitive position.

**Ensure financial strength and agility**

Disciplined capital allocation supports our ability to maximize asset value over the short, medium and long term while improving cost competitiveness, extending asset life and remaining within annual net capital spend targets. We assess opportunities to develop or acquire complementary energy infrastructure that protects and grows our business, enhances resilience under a changing energy mix and diversifies access to attractive supply and market regions within our risk preferences. Supported by our high-quality, diversified portfolio and core competencies in safety, operational excellence, and project execution, we aim to deliver predictable, low-risk cash flows and shareholder value across various economic cycles and energy transition scenarios.

**Our risk preferences**

The following is an overview of our risk philosophy:

• **financial strength and flexibility:** rely on internally generated cash flows, existing debt capacity, partnerships and portfolio management to finance new initiatives

• **known and acceptable project risks:** select investments with known, acceptable and manageable project execution risk, including stakeholder considerations, partnership agreements, human capital and capability constraints

• **business underpinned by strong fundamentals and policy support:** invest in assets with stable cash flows supported by strong underlying macroeconomic fundamentals, conducive policy and regulations and/or long-term contracts with creditworthy counterparties

• **manage credit metrics to ensure strong investment-grade ratings:** investment-grade ratings are an important competitive advantage and we manage leverage to ensure that strong access to capital on competitive terms is maintained while balancing the interests of equity and fixed income investors

• **prudent management of counterparty exposure:** limit counterparty concentration and sovereign risk; seek diversification and solid commercial arrangements underpinned by strong fundamentals.

**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 22 for more information about the non-GAAP measures we use, as well as the Financial results section in each business segment and Discontinued operations section for reconciliations to the most directly comparable GAAP measures.

As discussed on page 10 of the About this document section, TC Energy completed the Spinoff Transaction on October 1, 2024. To allow for a meaningful comparison, discussions throughout this MD&A are based on continuing operations unless otherwise noted. Refer to the Discontinued operations section for additional information.

**Cash flows**

Net cash provided by operations of $7.3 billion in 2025 was five per cent lower than 2024 primarily due to the timing of working capital changes, partially offset by higher funds generated from operations. Comparable funds generated from operations of $8.0 billion in 2025 were one per cent higher than 2024 primarily due to higher comparable EBITDA and risk management activities used to manage our foreign exchange exposure to net liabilities in Mexico and to U.S. dollar-denominated income, partially offset by lower distributions from our equity investments.

**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:

&nbsp;&nbsp;&nbsp;&nbsp;◦ 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:

&nbsp;&nbsp;&nbsp;&nbsp;◦ 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 2025 and comparative periods can be found on pages 24 &nbsp;&nbsp;&nbsp;&nbsp;and 25, the Financial results section in each business segment, and the Financial condition section. Non-GAAP measures for discontinued operations are found in the Discontinued operations section on page 89.

**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 Note 28, Changes in operating working capital, of our 2025 Consolidated financial statements. 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 on our 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 25 and 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.

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, of our 2025 Consolidated financial statements 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 <br>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 <br>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 Consolidated statement of income. Refer to Note 19, Long-term debt, of our 2025 Consolidated financial statements for additional information.

4In 2023 and 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**

**2025 versus 2024**

Comparable EBITDA from continuing operations in 2025 increased by $903 million compared to 2024 primarily due to the net result of the following:

• increased EBITDA from Canadian Natural Gas Pipelines primarily due to higher flow-through costs and incentive earnings on the NGTL System and Mainline and higher contributions from Coastal GasLink mainly resulting from the declared commercial in-service of the pipeline in fourth quarter 2024

• higher 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

• higher 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 and additional contract sales, partially offset by lower earnings from our equity investments and higher operational costs

• increased EBITDA from Corporate primarily due to costs in 2024 related to TC Energy's corporate services and governance functions that were not allocated to discontinued operations

• decreased Power and Energy Solutions EBITDA resulting from lower contributions from Bruce Power mainly due to the Unit 4 Major Component Replacement (MCR), higher operating costs, partially offset by a higher contract price; decreased Canadian Power earnings primarily due to lower realized power prices, partially offset by Natural Gas Storage and other contributions reflecting the net impact of lower business development costs and lower realized Alberta natural gas storage spreads

• the positive foreign exchange impact of a stronger U.S. dollar on the Canadian dollar equivalent comparable EBITDA in our U.S. dollar-denominated operations. As detailed on page 72, U.S. dollar-denominated comparable EBITDA from continuing operations increased by US$463 million compared to 2024, which was translated to Canadian dollars at an average rate of <br>1.40 in 2025 versus 1.37 in 2024. Refer to the Foreign exchange section for additional information.

**2024 versus 2023**

Comparable EBITDA from continuing operations in 2024 increased by $577 million compared to 2023 primarily due to the net result of the following:

• increased Power and Energy Solutions EBITDA primarily attributable to higher contributions from Bruce Power due to higher generation and a higher contract price, and Natural Gas Storage and other due to higher realized Alberta natural gas storage spreads, partially offset by decreased Canadian Power earnings primarily due to lower realized power prices net of lower natural gas fuel costs

• higher U.S. dollar-denominated EBITDA from Mexico Natural Gas Pipelines mainly due to increased equity earnings from Sur de Texas as a result of peso-denominated financial exposure and lower income tax expense

• increased EBITDA from Canadian Natural Gas Pipelines primarily due to higher flow-through costs and increased rate-base earnings on the NGTL System and Foothills, partially offset by lower earnings from Coastal GasLink related to the recognition <br>of a $200 million incentive payment in 2023

**Comparable earnings from continuing operations**

**2025 versus 2024**

Comparable earnings from continuing operations in 2025 were $211 million or $0.22 per common share lower than in 2024, and were primarily the net result of:

• changes in comparable EBITDA from continuing operations described above

• higher income tax expense primarily due to Mexico foreign exchange exposure and higher flow-through income taxes

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

• higher depreciation and amortization primarily due to higher depreciation rates on the NGTL System under the 2025-2029 NGTL Settlement and depreciation rate changes as a result of the Columbia Gas Settlement

• higher interest expense primarily due to lower capitalized interest resulting from the declared commercial in-service of &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;the Coastal GasLink pipeline in fourth quarter 2024 and increased levels of short-term borrowing

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

• higher net income attributable to non-controlling interests primarily due to the net effect of higher net income recognized from Columbia Gas Transmission, LLC (Columbia Gas) and Columbia Gulf Transmission, LLC (Columbia Gulf) assets, the completion of the Southeast Gateway pipeline in second quarter 2025 and the full year impact of the sale of a 13.01 per cent non-controlling equity interest in TGNH to the CFE, completed in second quarter 2024

• 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.

**2024 versus 2023**

Comparable earnings from continuing operations in 2024 were $31 million or $0.05 per common share lower than in 2023, and were primarily the net result of:

• changes in comparable EBITDA from continuing operations described above

• higher depreciation and amortization reflecting expansion facilities and new projects placed in service

• higher interest expense primarily due to long-term debt issuances, net of maturities, the foreign exchange impact of a stronger U.S. dollar in 2024 compared to 2023, higher interest rates on short-term borrowings in 2024 and the impact of interest expense allocated to discontinued operations for nine months in 2024 compared to a full year in 2023

• higher AFUDC predominantly due to spending on the Southeast Gateway pipeline project, partially offset by projects placed in service and the cessation of AFUDC on Tula in fourth quarter 2023

• 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

• higher interest income and other due to higher interest earned on short-term investments and a reduction in insurance-related provisions

• decreased income tax expense due to the impact of Mexico foreign exchange exposure and lower comparable earnings subject to income tax, partially offset by lower foreign income tax rate differentials and higher flow-through income taxes

• higher net income attributable to non-controlling interests primarily due to the net effect of the sale of a 40 per cent non-controlling equity interest in Columbia Gas and Columbia Gulf in fourth quarter 2023 and the full year impact of the &nbsp;&nbsp;&nbsp;&nbsp;13.01 per cent non-controlling equity interest in TGNH to the CFE, completed in second quarter 2024, partially offset by the divestiture of PNGTS in third quarter 2024.

**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 &nbsp;&nbsp;&nbsp;&nbsp;$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 <br>for 2026.

**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.

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.

NATURAL GAS PIPELINES BUSINESS

Our natural gas pipeline network transports natural gas from supply basins to LDCs, power generation plants, industrial facilities, interconnecting pipelines, LNG export terminals and other businesses across Canada, the U.S. and Mexico. Our network of pipelines taps into most major supply basins and transports over 30 per cent of continental daily natural gas needs through:

• wholly-owned natural gas pipelines – 63,185 km (39,260 miles)

• partially-owned natural gas pipelines – 30,986 km (19,253 miles).

In addition to our natural gas pipelines, we have regulated natural gas storage facilities in the U.S. with a total working gas capacity of 532 Bcf, making us one of the largest providers of natural gas storage and related services to key markets in North America.

Our Natural Gas Pipelines business is split into three operating segments representing its geographic diversity:&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Canadian Natural Gas Pipelines, U.S. Natural Gas Pipelines and Mexico Natural Gas Pipelines.

**Strategy**

Our strategy is to maximize the value of our existing natural gas pipeline systems in a safe and reliable manner while responding to the changing flow patterns of natural gas in North America. We also pursue new pipeline opportunities to add incremental value to our business.

Our key areas of focus include:

• primarily in-corridor expansion and extension of our existing significant North American natural gas pipeline footprint

• connections to new and growing industrial and electric power generation markets and LDCs

• expanding our systems in key locations in North America and developing new projects to provide connectivity to LNG export terminals, both operating and proposed

• connections to growing Canadian and U.S. shale gas and other supplies

• minimizing our GHG and methane emissions through operational excellence.

Each of these areas plays a critical role in meeting the transportation requirements for supply of and demand for natural gas in North America.

Our natural gas pipeline systems are helping solve the energy trilemma - energy security, affordability and sustainability. We believe natural gas provides a reliable, high-efficiency energy source that is helping to support the displacement of coal-fired power while backstopping the intermittency of renewable power sources across North America. We continue to improve operational efficiencies and factor sustainability-related considerations into our decision making around new projects, modernization, maintenance, electrification and enhanced leak detection. Our business model provides socioeconomic benefits as we work closely with Indigenous communities, community-based organizations, landowners and other stakeholders in alignment with our values and sustainability commitments.

**UNDERSTANDING OUR NATURAL GAS PIPELINES BUSINESS**

Natural gas pipelines move natural gas from major sources of supply to locations or markets that use natural gas to meet their energy needs.

Our natural gas pipelines business builds, owns and operates a network of natural gas pipelines across North America that connects gas production to interconnects, end-use markets and LNG export terminals. The network includes underground pipelines that transport natural gas predominantly under high pressure, compressor stations that act like pumps to move large volumes of natural gas along the pipeline, meter stations that record the amount of natural gas coming on the network at receipt locations and leaving the network at delivery locations and regulated natural gas storage facilities that provide services to customers and help maintain the overall balance of the pipeline systems.

**Regulation of tolls and cost recovery**

Our natural gas pipelines are generally regulated by the CER in Canada and FERC in the U.S. During March 2025, Mexico natural gas pipeline regulation transitioned from the CRE to the newly constituted CNE under the SENER.

These entities regulate the construction, operation and requested abandonment of pipeline infrastructure. For our rate regulated assets in Canada and the U.S., these regulators allow us to recover costs to operate the network by collecting tolls for services. These tolls generally include a return on our capital invested in the assets or rate base, as well as recovery of the rate base over time through depreciation. Other costs generally recovered through tolls include OM&A, taxes and interest on debt. The regulators generally review our costs to ensure they are reasonable and prudently incurred and approve tolls that provide a reasonable opportunity to recover those costs. In Mexico, while the majority of our capacity is subscribed under a long-term contractual rate, the regulator sets rates for interruptible services.

**Business environment and strategic priorities**

The North American natural gas pipeline network has been developed to connect diverse supply regions to domestic markets and to meet demand from LNG export facilities. Use and growth of this infrastructure is affected by changes in the location and relative cost of natural gas supplies, as well as changes in the location of markets and level of demand.

We have significant pipeline footprints that serve two of the most prolific supply regions of North America – the WCSB and the Appalachian basin. Our pipelines also source natural gas from other significant basins including the Rockies, Williston, Haynesville, Fayetteville and Anadarko basins. We expect continued growth in North American natural gas production to meet demand within growing domestic markets, particularly in the electric generation and industrial sectors which benefit from a relatively low natural gas price. In addition, North American supply is expected to benefit from increased natural gas demand in Mexico and growing access to international markets via LNG exports. We expect North American natural gas demand, including LNG exports, of approximately 155 Bcf/d by 2029, reflecting an increase of approximately 30 Bcf/d from 2024 levels.

As the world shifts toward a lower-carbon economy, we believe that further retirements of coal-fired power generation as well as export demand growth over the next five to 10 years will offer growth opportunities for base-load power from natural &nbsp;&nbsp;&nbsp;&nbsp;gas-fired generation. We expect that this projected growth in demand for natural gas, coupled with the anticipated increases in key producing areas like WCSB, onshore Gulf Coast, Appalachian and the Permian basin, will provide investment opportunities for pipeline infrastructure companies to build new facilities or increase utilization of their existing footprint. Modernizing our existing systems and assets and decarbonizing our energy consumption along our natural gas pipeline systems is expected to provide ongoing additional capital investment opportunities that will meet our risk preferences while supporting our GHG emissions reduction targets.

TC Energy **Management's discussion and analysis** 2025 \| 35

------

**Changing demand**

The abundant supply of natural gas has supported increased demand, particularly in the following areas:

• natural gas-fired power generation, including for use in emerging data centres

• global LNG exports

• petrochemical and industrial facilities

• Alberta oil sands.

Natural gas producers continue to progress opportunities to sell natural gas to global markets which involves connecting natural gas supplies to LNG export terminals, both operating and proposed, along the U.S. Gulf Coast and the east and west coasts of Canada, the U.S. and Mexico. The increasing export of natural gas to Mexico is driven by the CFE's need to serve existing markets and requires pipelines to serve new regions. We believe that natural gas is a key energy transition fuel for Mexico.

**Commodity prices**

The profitability of our natural gas pipelines business is not directly tied to commodity prices given we are a transporter of the commodity and the transportation tolls are not tied to the price of natural gas. However, the cyclical supply and demand nature of commodities and related pricing can have an indirect impact on our business where producers may choose to accelerate or delay development of gas reserves or, similarly on the demand side, projects requiring natural gas may be accelerated or delayed depending on market or price conditions.

**More competition**

Changes in supply and demand levels and locations have resulted in increased competition to provide transportation services throughout North America. Our well-distributed footprint of natural gas pipelines, particularly in the low-cost WCSB and the Appalachian basin, both of which are connected to North American demand centres, has placed us in a strong competitive position. Incumbent pipelines benefit from the connectivity and economies of scale afforded by the base infrastructure, as well as existing right-of-way and operational synergies given the increasing challenges of siting and permitting new pipeline construction and expansions. We have and will continue to offer competitive services to capture growing supply and North American demand that now includes access to global markets through LNG exports.

**Strategic priorities**

Our pipelines deliver the natural gas that millions of individuals and businesses across North America rely on for their energy needs. We are focused on capturing opportunities resulting from growing natural gas supply and connecting new markets while satisfying increasing demand for natural gas within existing markets. We are also focused on adapting our existing assets to changing natural gas flow dynamics and supporting our corporate-level sustainability commitments and targets.

Our goal is to place all of our projects into service on time and on budget while ensuring the safety of our people, the environment and the general public impacted by the construction and operation of these facilities. In 2026, we will continue to focus on the execution of our existing capital program, which includes initiating and advancing a suite of U.S. pipeline projects as well as investment in Canada, which includes the NGTL System and the Cedar Link project and investment in our Mexico gas pipelines. We will remain focused on capital discipline as we continue to pursue the next wave of growth opportunities.

Our marketing entities will complement our natural gas pipeline operations and generate non-regulated revenues by managing the procurement of natural gas supply and pipeline transportation capacity for natural gas customers within our pipeline corridors.

Canadian Natural Gas Pipelines

**UNDERSTANDING OUR CANADIAN NATURAL GAS PIPELINES SEGMENT**

The Canadian Natural Gas Pipelines business is subject to regulation by various federal and provincial governmental agencies. The CER has jurisdiction over our regulated Canadian natural gas interprovincial pipeline systems, while provincial regulators have jurisdiction over pipeline systems operating entirely within a single province. All of our major Canadian natural gas pipeline assets are regulated by the CER with the exception of the Coastal GasLink pipeline, which is regulated by the BC Energy Regulator.

For the interprovincial natural gas pipelines it regulates, the CER approves tolls, facilities and services that are in the public interest and provide a reasonable opportunity for the pipeline to recover its costs to operate the pipeline. Included in the overall toll is a return on the investment we have made in the assets, referred to as the return on equity. Generally, the CER has approved a deemed capital structure of 40 per cent equity and 60 per cent debt. Typically, tolls are based on the cost of providing service, including the cost of financing, divided by a forecast of volumes. Any variance in either costs or the actual volumes transported can result in an over-collection or under-collection of revenues that is normally trued up the following year in the calculation of the tolls for that period. The return on equity, however, would continue to be earned at the rate approved by the CER.

Subject to approval by the CER, we and our customers can also establish settlement arrangements that may have elements that vary from the typical toll-setting process. Settlements can include longer terms and mechanisms such as incentive agreements that can have an impact on the actual return on equity achieved. Examples include fixing the OM&A component in determining revenue requirements where variances are to the pipeline's account or shared between the pipeline and shippers.

The NGTL System is operating under the CER approved five-year negotiated revenue requirement settlement for 2025-2029&nbsp;&nbsp;&nbsp;&nbsp; (the 2025-2029 NGTL Settlement), which commenced on January 1, 2025 and includes an approved ROE of 10.1 per cent on &nbsp;&nbsp;&nbsp;&nbsp;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. The Canadian Mainline is operating under the 2021-2026 Mainline settlement, which includes an incentive to decrease costs and increase revenues.

**SIGNIFICANT EVENTS**

**NGTL System**

In the year ended December 31, 2025, the NGTL System placed approximately $0.2 billion of capacity projects in service.

**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. To date, approximately $1.1 billion of MYGP expansion facilities have received FID, with various in-service dates starting in 2026. We continue to evaluate plans for each MYGP facility to optimize cost and schedule. Completion of the MYGP is expected to enable approximately 1.0 Bcf/d of incremental system throughput.

**Valhalla North and Berland River Project**

We continue to advance construction of the Valhalla North and Berland River project. 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 Berland River section, which includes a new non-emitting electric compressor unit and associated facilities, has a target in-service date in the second half of 2026 and an estimated capital cost of $0.3 billion. The project is designed to provide incremental capacity on the NGTL System of approximately 428 TJ/d (400 MMcf/d).

**Coastal GasLink**

**Coastal GasLink Pipeline**

In October 2025, pursuant to the November 2024 commercial agreement executed with LNG Canada (LNGC) and each of the five LNGC participants, TC Energy received a one-time payment of $199 million in recognition of completed work and final cost settlement. This payment was recognized by TC Energy as an in-substance distribution from Coastal GasLink LP in our 2024 Consolidated financial statements.

Reclamation activities associated with post-construction work were completed in 2025. In addition, Coastal GasLink LP has resolved all material claims with a net positive recovery overall to Coastal GasLink LP. Refer to Note 30, Commitments, contingencies and guarantees, of our 2025 Consolidated financial statements for additional information.

**Indigenous Equity Option**

In March 2022, we announced the signing of option agreements to sell up to a 10 per cent equity interest in Coastal GasLink LP to Indigenous communities across the project corridor, from our current 35 per cent equity ownership. In January 2026, prospective investors entered into a binding window for these options, which is expected to remain in effect through to the end of 2026. Closing of the equity sale is subject to customary regulatory approvals and consents, including the consent of LNGC.

1Includes results from Foothills, Ventures LP, Great Lakes Canada and our proportionate share of income related to investments in TQM and Coastal GasLink, as well as general and administrative and business development costs related to our Canadian natural gas pipelines.

Canadian Natural Gas Pipelines segmented earnings were $2.2 billion in 2025 compared to $2.0 billion in 2024 and segmented losses of $0.1 billion in 2023, and included the following specific items, which have been excluded from our calculation of comparable EBITDA and comparable EBIT:

• a pre-tax gain on sale of non-core assets of $10 million in second quarter 2024

• a pre-tax impairment charge in 2023 of $2.1 billion related to our equity investment in Coastal GasLink LP.

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 $29 million in 2025 compared to 2024 primarily due to higher incentive earnings and increased by $5 million in 2024 compared to 2023 mainly due to a higher average investment base resulting from continued system expansions, partially offset by an incentive loss. The NGTL System is currently operating under the 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 an incentive for certain operating costs where variances from projected amounts and emissions savings are shared with customers. Refer to the Canadian Natural Gas Pipelines - Significant events section for additional information.

------

Net income for the Canadian Mainline increased by $14 million in 2025 compared to 2024 and by $14 million in 2024 compared to 2023 mainly as a result of 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 was $299 million higher in 2025 compared to 2024 primarily due to:

• higher flow-through depreciation and income taxes as well as higher incentive earnings, partially offset by lower flow-through financial charges and lower rate base earnings on the NGTL System

• higher contributions from Coastal GasLink mainly resulting from the declared commercial in-service of the pipeline in fourth quarter 2024

• higher incentive earnings, flow-through depreciation and income taxes on the Canadian Mainline.

Comparable EBITDA for Canadian Natural Gas Pipelines in 2024 was $53 million higher than 2023 primarily due to the <br>net effect of:

• higher flow-through income taxes, depreciation and financial charges, as well as higher rate-base earnings on the <br>NGTL System due to continued system expansions

• higher flow-through income taxes, financial charges and depreciation, as well as higher rate-base earnings on Foothills primarily due to the NGTL System/Foothills West Path Delivery Program completed in 2023

• earnings from Coastal GasLink in 2023 related to the recognition of a $200 million incentive payment upon meeting certain milestones.

**Depreciation and amortization**

Depreciation and amortization was $141 million higher in 2025 compared to 2024, primarily reflecting higher depreciation &nbsp;&nbsp;&nbsp;&nbsp;rates on the NGTL System under the 2025-2029 NGTL Settlement. Depreciation and amortization was $57 million higher in 2024 compared to 2023, mainly due to incremental depreciation on the NGTL System from expansion facilities that were placed in service.

**OUTLOOK**

**Comparable EBITDA and comparable earnings**

Net income for Canadian rate-regulated pipelines is affected by changes in investment base, ROE and deemed capital structure, as well as by the terms of toll settlements approved by the CER. Under the current regulatory model, return on rate base from Canadian rate-regulated natural gas pipelines is not materially affected by short-term fluctuations in the commodity price of natural gas, changes in throughput volumes or changes in contracted capacity levels.

Canadian Natural Gas Pipelines comparable EBITDA in 2026 is expected to be higher than 2025 mainly due to higher contributions from the NGTL System. Due to the flow-through treatment of certain costs on our Canadian rate-regulated pipelines, changes in these costs can impact our comparable EBITDA despite having no significant effect on comparable earnings. We expect our comparable earnings in 2026 for the NGTL System and the Canadian Mainline to be consistent &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;with 2025.

**Capital expenditures**

We incurred $1.3 billion of capital expenditures in 2025 in our Canadian Natural Gas Pipelines business on growth projects and maintenance capital expenditures. We expect to incur approximately $1.5 billion in 2026, primarily on NGTL System expansion projects and maintenance capital expenditures, all of which are immediately reflected in investment base and related earnings.

U.S. Natural Gas Pipelines

**UNDERSTANDING OUR U.S. NATURAL GAS PIPELINES SEGMENT**

The U.S. interstate natural gas pipeline business is subject to regulation by various federal, state and local governmental agencies. FERC, however, has comprehensive jurisdiction over our U.S. interstate natural gas business. FERC approves maximum transportation rates that are cost-based and are designed to recover the pipeline's investment, operating expenses and a reasonable return for our investors. In the U.S., we have the ability to contract for negotiated or discounted rates with shippers.

FERC does not require U.S. interstate pipelines to calculate rates annually, nor do they generally allow for the collection or refund of the variance between actual and expected revenues and costs into future years. This difference in U.S. regulation from the Canadian regulatory environment puts our U.S. pipelines at risk for the difference in expected and actual costs and revenues between rate cases. If revenues no longer provide a reasonable opportunity to recover our costs, we can file with FERC for a new determination of rates, subject to any moratorium in effect. Similarly, FERC or our shippers may institute proceedings to lower rates if they consider the return on capital invested to be unjust or unreasonable.

Similar to Canada, we can also establish settlement arrangements with our U.S. shippers that are ultimately subject to approval by FERC. Rate case moratoriums for a period of time, before either we or the shippers can file for a rate review, are common for a settlement in that they provide some certainty for shippers in terms of rates, eliminate the costs associated with frequent rate proceedings for all parties and can provide an incentive for pipelines to lower costs.

**PHMSA Pipeline Safety Regulations**

Most of our U.S. natural gas pipeline systems are subject to federal pipeline safety statutes and regulations enacted and administered by PHMSA. PHMSA will continue to produce new rules affecting numerous aspects of operation and maintenance of our pipeline system. PHMSA's priorities are generally dictated by legislation which is influenced by numerous stakeholders and informed by learnings from recent industry incidents and stakeholder priorities. When PHMSA implements new rules, TC Energy seeks recovery of additional expenditures driven by such rules in future rate cases and modernization settlements.

**SIGNIFICANT EVENTS**

**Columbia Gas Section 4 Rate Case**

Columbia Gas reached a settlement with its customers effective April 2025 and received FERC approval in October 2025. As part of the settlement, there is a moratorium on any further rate changes until March 31, 2028. Columbia Gas must file for new rates with an effective date no later than April 1, 2031. The settlement also included additional rate step ups in April 2026 and April 2027 to reflect anticipated modernization-related spend. In fourth quarter 2025, previously accrued rate refund liabilities, including interest, were refunded to customers.

**ANR and Great Lakes Section 4 Rate Cases**

In April 2025, ANR and Great Lakes each filed Section 4 Rate Cases with FERC requesting an increase to their respective maximum transportation rates effective November 1, 2025, subject to refund. We will pursue a collaborative process to find a mutually beneficial outcome with our customers through settlement.

**Northwoods Project**

In April 2025, we approved the Northwoods project, an expansion project on our ANR system designed to provide 0.4 Bcf/d of capacity to serve natural gas-fired electric generation demand in the U.S. Midwest, including data centres and overall economic growth. The project involves pipeline looping, compressor facility additions as well as other system updates, with an anticipated in-service date of late 2029 and an estimated project cost of approximately US$0.9 billion.

**East Lateral XPress**

The East Lateral XPress project, an expansion project on the Columbia Gulf system that connects supply to U.S. Gulf Coast LNG export markets, was placed in service in May 2025, with a total project cost of approximately US$0.3 billion.

**Ventura XPress Project**

The Ventura XPress project, a set of ANR projects designed to improve base system reliability and allow for additional long-term contracted transportation services to a point of delivery on the Northern Border pipeline at Ventura, Iowa, was placed in service in October 2025 with a total project cost of approximately US$0.2 billion.

A stronger U.S. dollar in 2025 and 2024 had a positive impact on the Canadian dollar equivalent segmented earnings from our U.S. dollar-denominated operations. 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.

------

Comparable EBITDA for U.S. Natural Gas Pipelines was US$212 million higher in 2025 than 2024 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 for additional information

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

• increased earnings from our mineral rights business due to higher commodity prices

• decreased earnings as a result of the sale of our 61.7 per cent equity interest in PNGTS, which was completed in August 2024

• decreased equity earnings from Iroquois and Millennium

• decreased earnings due to higher operational costs, reflective of system utilization and projects placed in service across our footprint.

Comparable EBITDA for U.S. Natural Gas Pipelines was US$46 million higher in 2024 than 2023 primarily due to the net effect of:

• incremental earnings from growth and modernization projects placed in service, as well as increased earnings from additional contract sales on ANR and Great Lakes

• increased equity earnings from Northern Border

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

• decreased earnings as a result of the sale of our 61.7 per cent equity interest in PNGTS, which was completed in August 2024

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

• reduced earnings from our mineral rights business due to lower commodity prices.

**Depreciation and amortization**

Depreciation and amortization was US$46 million higher in 2025 compared to 2024 and US$5 million higher in 2024 compared to 2023. The increase in depreciation is primarily due to new projects placed in service and depreciation rate changes as a result of the Columbia Gas Settlement, partially offset by the impact of the sale of PNGTS in 2024.

**OUTLOOK**

**Comparable EBITDA**

Our U.S. natural gas pipelines are largely backed by long-term take-or-pay contracts that are expected to deliver stable and consistent financial performance. Our ability to retain customers and recontract or sell capacity at favourable rates is influenced by prevailing market conditions and competitive factors, including alternatives available to end-use customers in the form of competing natural gas pipelines and supply sources, as well as broader conditions that impact demand from certain customers or market segments. Comparable EBITDA is also affected by operational and other costs, which can be impacted by safety, environmental and other regulatory decisions, as well as customer credit risk.

U.S. Natural Gas Pipelines comparable EBITDA in 2026 is expected to be higher than 2025 primarily due to full year in-service of the East Lateral XPress, Ventura XPress, VR and WR projects, as well as a full year of increased rates on Columbia Gas as a result of the Columbia Gas Settlement. Our pipeline systems continue to see historically strong demand for service and we anticipate that during 2026, our assets will maintain the high utilization levels experienced in 2025. These positive results are expected to be partially offset by higher operational costs, reflective of continued increases to system utilization across our footprint and an anticipated increase in property taxes from capital projects placed in service.

**Capital expenditures**

We incurred a total of US$2.4 billion of capital expenditures in 2025 on our U.S. natural gas pipelines and expect to incur approximately US$2.4 billion in 2026 primarily on our Columbia Gas and ANR expansion projects and Gillis Access expansion project, as well as Columbia Gas and ANR maintenance capital expenditures, the return on and recovery of which, is expected to be reflected in future tolls. We expect net capital expenditures in 2026 to be approximately US$2.0 billion after considering capital expenditures attributable to the non-controlling interests of entities we control.

Mexico Natural Gas Pipelines

**UNDERSTANDING OUR MEXICO NATURAL GAS PIPELINES SEGMENT**

For over a decade, Mexico has been undergoing a significant transition from fuel oil and diesel as its primary energy sources for electric generation to using natural gas. As a result, new natural gas pipeline infrastructure has been and continues to be required to meet the growing demand for natural gas. The CFE, Mexico's state-owned electric utility, is the primary counterparty on all of our existing pipelines under long-term contracts, which are predominately denominated in U.S. dollars. These fixed-rate contracts are generally designed to recover the cost of service and provide a return on and of invested capital. As the pipeline developer and operator, we are generally at risk for operating and construction costs. Our Mexico pipelines also have regulatory approved tariffs, services and related rates for other potential users.

**SIGNIFICANT EVENTS**

**TGNH Strategic Alliance with the CFE**

The Southeast Gateway pipeline is in service and we commenced the collection of tolls beginning May 2025. In July 2025, the newly constituted CNE approved our regulated rates required to provide service to potential future interruptible service users on the Southeast Gateway pipeline other than the CFE.

In 2024, the CFE became an equity partner in TGNH with a 13.01 per cent equity interest. The CFE's equity in TGNH is expected to increase to a maximum of 15 per cent, subject to regulatory approvals, and will increase to approximately 35 per cent upon expiry of the contract in 2055.

**OUTLOOK**

**Comparable EBITDA**

Mexico Natural Gas Pipelines comparable EBITDA reflects long-term, stable, principally U.S. dollar-denominated transportation contracts that are affected by the cost of providing service and includes our share of equity income from our 60 per cent equity interest in the Sur de Texas pipeline. Due to the long-term nature of the underlying transportation contracts, comparable EBITDA is generally consistent year-over-year except when new assets are placed in service. Comparable EBITDA for 2026 is expected to be higher than 2025 due to the Southeast Gateway project, which was completed in second quarter 2025.

**Capital expenditures**

We incurred US$0.2 billion of capital expenditures in 2025 primarily related to the construction of the Southeast Gateway pipeline and maintenance capital expenditures. We expect to incur approximately US$0.2 billion in 2026 to finalize construction of pipeline projects in Mexico.

**NATURAL GAS PIPELINES – BUSINESS RISKS**

The following are risks specific to our Natural Gas Pipelines business. Refer to page 94 for information about general risks related to TC Energy as a whole, including other operational, safety and financial risks, as well as our approach to risk management.

**Production levels within supply basins**

The NGTL System and our pipelines downstream depend largely on supply from the WCSB. Columbia Gas and its connecting pipelines largely depend on Appalachian supply. We continue to monitor any changes in our customers' natural gas production plans and how these may impact our existing assets and new project schedules. There is competition amongst pipelines to connect to major basins. An overall decrease in production and/or increased competition for supply could reduce throughput on our connected pipelines that, in turn, could negatively impact overall revenues generated. The WCSB and Appalachian basins are two of the most prolific and cost-competitive basins in North America and have considerable natural gas reserves. However, the amount actually produced depends on many variables including the price of natural gas and natural gas liquids, basin-on-basin competition, pipeline and gas-processing tolls, demand within the basin, changes in policy and regulations and the overall value of the reserves, including liquids content.

**Market access** 

**Competition for greenfield pipeline expansion**

We face competition from other pipeline companies seeking to invest in greenfield natural gas pipeline development opportunities. This competition could result in fewer available projects that meet our investment hurdles or projects that proceed with lower overall financial returns. While renewable deployments are expected to garner an increasing portion of future energy needs, including in the power generation sector, aggregate natural gas demand across all sectors, including LNG exports, is still projected to grow under the most aggressive renewable deployment forecasts. The reliability of natural gas is an important factor in the successful wide-scale deployment of renewables with more intermittent capabilities.

**Demand for pipeline capacity**

Demand for pipeline capacity ultimately drives the sale of pipeline transportation services and is impacted by supply and market competition, variations in economic activity, weather variability, natural gas pipeline and storage competition, energy conservation, as well as demand for and prices of alternative sources of energy. Renewal of expiring contracts and the opportunity to charge a competitive toll depends on the overall demand for transportation service. A decrease in the level of demand for our pipeline transportation services could adversely impact revenues, although overall utilization of our pipeline capacity continues to grow and warrant further investment and expansion.

**Commodity prices**

The cyclical supply and demand nature of commodities and related pricing can have a secondary impact on our business where our shippers may choose to accelerate or delay certain projects. This can impact the timing of demand for transportation services and/or new natural gas pipeline infrastructure. Disruptions in the energy supply chain can result in price volatility and a decline in natural gas prices that could impact our shippers' financial condition and their ability to meet their transportation service cost obligations.

TC Energy **Management's discussion and analysis** 2025 \| 53

------

**Regulatory risk**

Decisions and evolving policies by regulators and other government authorities, including changes in regulation, can impact the approval, timing, construction, operation and financial performance of our natural gas pipelines. There is a risk that decisions are delayed or are not favourable and could therefore adversely impact construction costs, in-service dates, anticipated revenues and the opportunity to further invest in our systems. There is also risk of a regulator disallowing recovery of a portion of our costs, now or at some point in the future.

The regulatory approval process for larger infrastructure projects, including the time it takes to receive a decision, could be delayed or lead to an unfavourable decision due to evolving public opinion and government policy related to natural gas pipeline infrastructure development. If regulatory decisions are subsequently challenged in courts, this could result in further impacts to project costs and schedule delays.

Increased scrutiny of construction and operations processes by the regulator or other enforcing agencies has the potential to delay construction, increase operating costs or require additional capital investment. There is a risk of an adverse impact to income if these costs are not fully recoverable and/or reduce the competitiveness of tolls charged to customers.

We continuously manage these risks by monitoring legislative and regulatory developments and decisions to determine the possible impact on our natural gas pipelines business and developing rate, facility and tariff applications that account for and mitigate these risks where possible.

**Governmental risk**

Shifts in government policy or changes in government can impact our business. More complex regulatory processes, broader consultation requirements, more restrictive emissions and/or carbon pricing policies and changes to environmental regulations can impact our operations and opportunities for continued growth. We are committed to working with all levels of government to ensure our business benefits and risks are understood and mitigation strategies are implemented.

**Construction and operations**

Constructing and operating our pipelines to ensure transportation services are provided safely and reliably is essential to the success of our business. Interruptions in our pipeline operations impacting throughput capacity may result in reduced revenues and can affect corporate reputation, as well as customer and public confidence in our operations. We manage this by investing in a highly skilled workforce, hiring third-party inspectors during construction, operating prudently, monitoring our pipeline systems continuously, using risk-based preventive maintenance programs and making effective capital investments. We use pipeline inspection equipment to regularly check the integrity of our pipelines and repair or replace sections when necessary. &nbsp;&nbsp;&nbsp;&nbsp;We also calibrate meters regularly to ensure accuracy and employ robust reliability and integrity programs to maintain compression equipment and safe and reliable operations.

**UNDERSTANDING OUR POWER AND ENERGY SOLUTIONS BUSINESS**

**Canadian Power**

**Canadian Power Generation & Marketing**

We own and operate approximately 1,200 MW of power supply in Canada, excluding our investment in Bruce Power. In Alberta we own five facilities: four natural gas-fired cogeneration and one solar. We exercise a disciplined operating strategy to maximize revenues. Our marketing group sells uncommitted power while also buying and selling power and natural gas to maximize earnings. To reduce commodity price exposure associated with uncontracted power, we sell a portion of this output in forward sales markets when acceptable contract terms are available while the remainder is retained to be sold in the spot market or under short-term forward arrangements. The objective of this strategy is to maintain adequate power supply to fulfill our sales obligations if we have unexpected plant outages and enable us to capture opportunities to increase earnings in periods of high spot prices.

**Bruce Power**

Bruce Power is a nuclear power generation facility located near Tiverton, Ontario and is comprised of eight nuclear units with a combined capacity of approximately 6,580 MW. Bruce Power leases the facilities from OPG, has no spent fuel risk and will return the facilities to OPG for decommissioning at the end of the lease. We have a 48.3 per cent equity interest in Bruce Power.

Results from Bruce Power will fluctuate primarily due to units being offline for the MCR program and the frequency, scope and duration of planned and unplanned maintenance outages.

Through a long-term agreement with the IESO, Bruce Power is progressing a series of incremental life-extension investments to extend the operating life of the facility to 2064. This agreement represents an extension and material amendment to the earlier agreement that led to the refurbishment of Units 1 and 2 at the site. Under the amended agreement, which took economic effect in 2016, Bruce Power began investing in life extension activities for Units 3 through 8 to support the long-term refurbishment programs, known as the Asset Management program. Investment in the Asset Management program is designed to result in near-term life extensions of each of the six units up to the planned major refurbishment outages and beyond. The Asset Management program includes the one-time refurbishment or replacement of systems, structures or components that are not within the scope of the MCR program, which focuses on the actual replacement of the key, life-limiting reactor components. The MCR program is designed to add at least 35 years of operational life to each of the six units.

The Unit 6 MCR, the first of the six-unit MCR life extension program, was completed in third quarter 2023. The Unit 3 MCR and Unit 4 MCR, which are the second and third unit in the MCR program, commenced in first quarter 2023 and 2025, with expected completion dates in 2026 and 2028, respectively. The Unit 5 MCR final cost and schedule estimate was verified by the IESO on April 2, 2025. The Unit 5 MCR is expected to commence in fourth quarter 2026 with a return to service in early 2030. Investments in the remaining two units' MCR programs are expected to continue through 2033. Future MCR investments will be subject to discrete decisions for each unit with specified off-ramps available for Bruce Power and the IESO.

Along with the MCR life extension program, Bruce Power's Project 2030 has a goal of achieving site peak output (capability) of 7,000 MW by 2033 in support of the province of Ontario's climate change targets and future clean energy needs. Project 2030 is focused on continued asset optimization, innovation and leveraging new technology to increase site capability. Project 2030 is being implemented in three stages with the first two stages and Stage 3a fully approved for execution. The program commenced in 2019 with a site capability of 6,430 MW and closed out 2025 at approximately 6,580 MW; a net gain of approximately 150 MW. Upon completion of Stage 1, 2 and 3a, the site is projected to reach 6,840 MW. All three stages are being implemented in parallel to the MCR program.

As part of the life extension and refurbishment agreement, Bruce Power receives a uniform contract price for all units which includes certain flow-through items such as fuel and lease expense recovery. The contract also provides for payment if the IESO requests a reduction in Bruce Power's generation to balance the supply of and demand for, electricity and/or manage other operating conditions of the Ontario power grid. The amount of the reduction is considered deemed generation, for which Bruce Power is paid the contract price.

56 \| TC Energy **Management's discussion and analysis** 2025

------

The contract price is subject to adjustments for the return of and on capital invested at Bruce Power under the Asset Management and MCR programs, along with various other pricing adjustments that allow for a better matching of revenues and costs over the long term. As part of the amended agreement, Bruce Power is also required to share operating cost efficiencies with the IESO for better than planned performance. These efficiencies are reviewed every three years and paid out on a monthly basis over the subsequent three-year period. No operating cost efficiencies for the 2025 to 2027 period have been provided for at December 31, 2025 and no operating cost efficiencies were realized for the 2019 to 2024 period.

Bruce Power is a global supplier of Cobalt-60, a medical isotope used in the sterilization of medical equipment and to &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;treat certain types of cancer. Cobalt-60 is produced during Bruce Power's generation of electricity, harvested during certain &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;planned maintenance outages and provided for medical use in the treatment of brain tumours and breast cancer. In addition, Bruce Power harvests Lutetium-177, a medical isotope used in the treatment of prostate cancer and neuroendocrine tumours. Lutetium-177 is generated and harvested while Bruce Power is generating electricity. Isotope production includes a partnership with the Saugeen Ojibway Nation, on whose traditional territory the Bruce Power facilities are located. Furthermore,&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Bruce Power has committed to building a hot cell facility in Bruce County, for the purposes of streamlining the supply chain for the short-lived Lutetium-177 to ensure it reaches cancer patients around the world in a timely fashion.

**Power Purchase Agreements**

We have approximately 350 MW of wind generation PPAs and associated environmental attributes in the U.S. These PPAs allow us to generate incremental earnings by offering renewable power products to our customers.

**Other Energy Solutions**

**Canadian Natural Gas Storage**

Our Canadian natural gas storage business helps balance seasonal and short-term supply and demand while also adding flexibility to the delivery of natural gas to markets in Alberta and the rest of North America. Market volatility creates arbitrage opportunities and our natural gas storage facilities also give us and our customers the ability to capture value from short-term price movements. The natural gas storage business is affected by changes in seasonal natural gas price spreads which are generally determined by the differential in natural gas prices between the traditional summer injection and winter withdrawal seasons. In addition, the business may be affected by pipeline restrictions in Alberta which limit the ability to capture price differentials.

Our natural gas storage business contracts with third parties, typically participants in the Alberta and interconnected gas markets, for a fixed fee to provide natural gas storage services on a short, medium and/or long-term basis.

We also enter proprietary natural gas storage transactions which include a forward purchase of our own natural gas to be injected into storage and a simultaneous forward sale of natural gas for withdrawal at a later period, typically during the winter withdrawal season. By matching purchase and sales volumes on a back-to-back basis, we lock in future positive margins, effectively eliminating our exposure to changes in natural gas prices for these transactions.

Power and Energy Solutions segmented earnings decreased by $329 million in 2025 compared to 2024 and increased by

$98 million in 2024 compared to 2023 and included the following specific items, which have been excluded from our calculation of comparable EBITDA and comparable EBIT:

• 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 $206 million in 2025 compared to 2024 primarily due to the net effect of:

• lower Bruce Power contributions from reduced generation, mainly attributable to the Unit 4 MCR and higher operating costs, partially offset by a higher contract price. Refer to the Bruce Power section for additional information

• decreased Canadian Power results primarily from lower realized power prices

• increased Natural Gas Storage and other contributions reflecting lower business development costs, partially offset by decreased realized Alberta natural gas storage spreads in first quarter 2025 and reduced contributions from our U.S. marketing business.

Comparable EBITDA for Power and Energy Solutions increased by $194 million in 2024 compared to 2023 primarily due to the net effect of:

• higher contributions from Bruce Power primarily due to higher generation resulting from fewer outage days in 2024 and a higher contract price, partially offset by increased operating expenses and higher depreciation expense. Additional financial and operating information on Bruce Power is provided below

• increased Natural Gas Storage and other results primarily due to higher realized Alberta natural gas storage spreads and higher contributions from our U.S. marketing business, partially offset by increased business development costs in 2024

• decreased Canadian Power financial results primarily from lower realized power prices, partially offset by lower natural gas fuel costs.

**OUTLOOK**

**Comparable EBITDA**

Power and Energy Solutions comparable EBITDA in 2026 is expected to be higher than 2025 primarily due to increased Bruce Power equity income with the expected return to service of Unit 3 in early third quarter 2026 following its MCR outage, a higher contract price, and a reduction in non-MCR planned outage days. These positive factors are expected to be partially offset by the commencement of the Unit 5 MCR outage in fourth quarter 2026. Contributions from Canadian Power are expected to be lower due to decreased generation and higher natural gas prices, partially offset by increased Alberta power prices. Natural Gas Storage and other earnings are expected to be consistent with 2025.

Planned maintenance at Bruce Power in 2026 is scheduled on Unit 8 in the first quarter and on Unit 1 in the third quarter. Excluding the MCR programs for Units 3, 4, and 5, average plant availability for 2026 is expected to be in the low-90 per cent range.

**Capital expenditures**

We incurred $0.9 billion of capital expenditures in 2025, primarily for our share of Bruce Power's Unit 3 and 4 MCR and Asset Management programs, along with maintenance capital projects across the segment. For 2026, we expect a similar level of capital investment, approximately $1.0 billion, mainly allocated to our share of Bruce Power's Unit 4 and Unit 5 MCR and Asset Management programs.

**BUSINESS RISKS**

The following are risks specific to our Power and Energy Solutions business. Refer to page 94 for information about general risks related to TC Energy as a whole, including other operational, safety and financial risks, as well as our approach to risk management.

**Fluctuating power and natural gas market prices**

Much of the physical power generation and fuel used in our power operations is currently exposed to commodity price volatility. These exposures are partially mitigated through long-term contracts and hedging activities including selling and purchasing power and natural gas in forward markets. As contracts expire, new contracts are entered into at prevailing market prices.

Our two eastern Canadian natural gas-fired assets are fully contracted and not materially impacted by fluctuating spot power and natural gas prices. As the contracts on these assets expire it is uncertain if we will be able to re-contract on similar terms and may face future commodity exposure.

Our natural gas storage business is subject to fluctuating seasonal natural gas price spreads which are generally determined by the differential in natural gas prices between the traditional summer injection and winter withdrawal seasons. In addition, the business may be affected by pipeline restrictions in Alberta which limit the ability to capture price differentials.

**Plant availability**

Operating our plants to ensure services are provided safely and reliably as well as optimizing and maintaining their availability are essential to the continued success of our Power and Energy Solutions business. Unexpected outages or extended planned outages at our power plants can increase maintenance costs as well as lower plant output, revenues and margins. We may also have to buy power or natural gas on the spot market to meet our delivery obligations. We manage this risk by investing in a highly skilled workforce, operating prudently, running comprehensive risk-based preventive maintenance programs and making effective capital investments.

**Regulatory**

We operate in Canada and the U.S. in both regulated and deregulated power markets. These markets are subject to various federal, provincial and state regulations. As power markets evolve, there is the potential for regulatory bodies to implement new rules that could negatively affect us as a generator and marketer of electricity. These may be in the form of market rule or market design changes, changes in the interpretation and application of market rules by regulators, price caps, emission controls, emissions costs, cost allocations to generators and out-of-market actions taken by others to build excess generation, all of which may negatively affect the price of power. In addition, our development projects rely on an orderly permitting process and any disruption to that process can have negative effects on project schedules and costs. We are an active participant in formal and informal regulatory proceedings and take legal action where required.

**Compliance**

Market rules, regulations and operating standards apply to our power business based on the jurisdictions in which they operate. Our trading and marketing activities may be subject to fair competition and market conduct requirements as well as specific rules that apply to physical and financial transactions in deregulated markets. Similarly, our generators may be subject to specific operating and technical standards relating to maintenance activities, generator availability and delivery of power and power-related products. While significant efforts are made to ensure we comply with all applicable statutory requirements, situations including unforeseen operational challenges, lack of rule clarity and the ambiguous and unpredictable application of requirements by regulators and market monitors occasionally arise and create compliance risk. Deemed contravention of these requirements may result in mandatory mitigation activities, monetary penalties, imposition of operational limitations, or <br>even prosecution.

**Weather**

Significant changes in temperature and weather, including the potential impacts of climate change, have many effects on our business, ranging from the impact on demand, availability and commodity prices, to efficiency and output capability. Extreme temperature and weather can affect market demand for power and natural gas and can lead to significant price volatility, as well as restrict the availability of natural gas and power if demand is higher than supply. Fluctuations in seasonal weather patterns or temperature can affect the efficiency and production of our natural gas-fired power plants.

64 \| TC Energy **Management's discussion and analysis** 2025

------

**Competition**

We face various competitive forces that impact our existing assets and prospects for growth. For instance, our existing power plants will compete over time with new power capacity. New supply could come in several forms including supply that employs more efficient power generation technologies or additional supply from regional power transmission interconnections. We also face competition from other power companies in Canada and the U.S., as well as in the development of greenfield power plants. Traditional and non-traditional participants are entering the growing lower-carbon economy in North America and, as a result, we face competition in building lower-carbon energy solutions.

**Execution and capital costs**

We make substantial capital commitments developing power generation infrastructure based on the assumption that these assets will deliver an attractive return on investment. While we carefully consider the scope and expected costs of our capital projects, we are exposed to execution and capital cost overrun risk which may impact our return on these projects. We mitigate this risk by implementing comprehensive project governance and oversight processes and through the structuring of engineering, procurement and construction contracts with reputable counterparties.

**SIGNIFICANT EVENTS**

**2016 Columbia Pipeline Acquisition Lawsuit**

In 2018, former shareholders of Columbia Pipeline Group Inc. (CPG) commenced a class action lawsuit related to the acquisition of CPG by TC Energy in 2016. In 2023, the Delaware Chancery Court (the Court) found that the former CPG executives breached their fiduciary duties, that the former CPG Board breached its duty of care in overseeing the sale process and that TC Energy aided and abetted those breaches. TC Energy's allocated share of damages was an estimated US$350 million, plus post-judgment interest. TC Energy appealed the decision to the Delaware Supreme Court and on June 17, 2025, the Supreme Court issued its decision reversing the Court's finding of liability against TC Energy. On July 10, 2025, the Court granted the final order vacating its prior judgment and dismissing plaintiffs' claims against TC Energy. As a result, this matter is now concluded in TC Energy's favour with no liability. There is no further right of appeal.

AFUDC decreased by $331 million in 2025 compared to 2024. The increase in Canadian dollar-denominated AFUDC is primarily related to NGTL System expansion projects. The decrease in U.S. dollar-denominated AFUDC is primarily due to 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, partially offset by capital expenditures on our U.S. natural gas pipeline projects.

AFUDC increased by $209 million in 2024 compared to 2023. The decrease in Canadian dollar-denominated AFUDC is primarily related to NGTL System expansion projects placed in service in 2024. The increase in U.S. dollar-denominated AFUDC is primarily due to capital expenditures on the Southeast Gateway pipeline project and U.S. natural gas pipeline projects in 2024, partially offset by the suspension of AFUDC on the assets under construction for the Tula pipeline project due to the delay of an FID and placing the lateral section of Villa de Reyes pipeline in service in August 2023.

1In October 2023, we completed the sale of a 40 per cent non-controlling equity interest in Columbia Gas and Columbia Gulf to Global Infrastructure Partners.

2In second quarter 2024, the CFE became a partner in TGNH with a 13.01 per cent equity interest in TGNH. Refer to the Mexico Natural Gas Pipelines – Significant events section for additional information.

3Tax equity investors own 100 per cent of the Class A Membership Interests, to which a percentage of earnings, tax attributes and cash flows are allocated. We own 100 per cent of the Class B Membership Interests.

4The sale of PNGTS was completed in August 2024.

Net income attributable to non-controlling interests decreased by $106 million in 2025 compared to 2024 and increased by &nbsp;&nbsp;&nbsp;&nbsp;$535 million in 2024 compared to 2023 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 $23 million in 2025 compared to 2024. The increase is primarily due to higher net income recognized from the Columbia Gas and Columbia Gulf assets, the net impact of higher EBITDA and lower AFUDC in TGNH following the Southeast Gateway pipeline's completion in second quarter 2025, the full year impact of the 13.01 per cent TGNH non-controlling equity interest sale to the CFE, which was completed in second quarter 2024 and the overall impact of foreign exchange. This was partially offset by the divestiture of PNGTS in third quarter 2024.

Net income attributable to non-controlling interests included in comparable earnings increased by $474 million in 2024 compared to 2023 primarily due to the sale of a 40 per cent non-controlling equity interest in Columbia Gas and Columbia Gulf to Global Infrastructure Partners in fourth quarter 2023 and the 13.01 per cent non-controlling equity interest in TGNH to the CFE, which was completed in second quarter 2024.

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. <br>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. <br>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 year 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 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 Consolidated statement of income. Refer to the Other information – Financial risks and Financial instruments sections for additional information.

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. More information on how our credit ratings can impact our financing costs, liquidity and operations is available in our Annual Information Form available on SEDAR+ (www.sedarplus.ca).

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

**Financial Plan**

Our capital program is comprised of approximately $21 billion of secured projects, as well as our projects under development, which are subject to key corporate and regulatory approvals. As discussed throughout this Financial condition section, our capital program is expected to be financed through our growing internally-generated cash flows and a combination of other funding options which may include:

• senior debt

• hybrid securities

• preferred shares

• asset divestitures and capital rotation

• project financing

• potential involvement of strategic or financial partners.

In addition, we may access additional funding options, as deemed appropriate, including common shares issued from treasury under our DRP and discrete common equity issuances.

**Balance sheet analysis - from continuing operations**

At December 31, 2025, excluding discontinued operations, our current assets totaled $6.1 billion and current liabilities amounted to $9.8 billion, leaving us with a working capital deficit of $3.7 billion compared to $4.8 billion at December 31, 2024. Our working capital deficiency is considered to be in the normal course of business and is managed through:

• our ability to generate predictable and growing cash flows from operations

• a total of $7.8 billion of TCPL committed revolving credit facilities, of which $7.2 billion of short-term borrowing capacity remains available, net of $0.6 billion backstopping outstanding commercial paper balances, and arrangements for a further $2.0 billion of demand credit facilities, of which $1.3 billion remains available as of December 31, 2025

• additional $2.1 billion committed revolving credit facilities at certain of our subsidiaries and affiliates, of which $1.5 billion of short-term borrowing capacity remains available as of December 31, 2025, net of $0.6 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.

Our total assets from continuing operations at December 31, 2025 were $118.6 billion compared to $117.9 billion at December 31, 2024 reflecting our 2025 capital spending program, equity investments and working capital, partially offset by a weaker U.S. dollar at December 31, 2025 compared to December 31, 2024 on translation of our U.S. dollar-denominated assets.

At December 31, 2025 our total liabilities from continuing operations were $81.7 billion, compared to $79.6 billion at December 31, 2024 due to the net effect of movements in debt, working capital and a weaker U.S. dollar at December 31, 2025 compared to December 31, 2024 on translation of our U.S. dollar-denominated liabilities.

Provisions of various trust indentures, credit arrangements and other agreements with certain of our subsidiaries can restrict those subsidiaries' ability and, in certain cases, our ability to declare and pay dividends or make distributions under certain circumstances. In the opinion of management, these provisions do not currently restrict our ability to declare or pay dividends. These trust indentures and credit arrangements also require us to comply with various affirmative and negative covenants and maintain certain financial ratios. We were in compliance with all of our financial covenants at December 31, 2025.

This is offset by a corresponding deferred tax recovery resulting in no net impact to tax expense.

**Net cash provided by operations**

Net cash provided by operations decreased by $350 million in 2025 compared to 2024 primarily due to the timing of working capital changes, partially offset by higher funds generated from operations.

Net cash provided by operations increased by $428 million in 2024 compared to 2023 primarily due to 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 $106 million in 2025 compared to 2024 primarily due to higher comparable EBITDA and risk management activities used to manage our foreign exchange exposure to net liabilities in Mexico and to U.S. dollar-denominated income, partially offset by lower distributions from our equity investments.

Comparable funds generated from operations decreased by $90 million in 2024 compared to 2023 primarily due to lower comparable earnings, partially offset by increased distributions from our equity investments.

***Capital expenditures***

Capital expenditures in 2025 were incurred primarily for the advancement of the Columbia Gas and ANR projects, the NGTL System expansion as well as maintenance capital expenditures. Lower capital expenditures in 2025 compared to 2024 reflect the completion of the Southeast Gateway pipeline in second quarter 2025, partially offset by increased spending on ANR projects.

***Capital projects in development***

Costs incurred during 2025 on Capital projects in development were attributable to spending on projects in the Power and Energy Solutions segment.

***Contributions to equity investments***

Contributions to equity investments decreased in 2025 compared to 2024 mainly due to lower funds advanced to Coastal GasLink LP through the subordinated loan agreement.

Contributions to equity investments decreased in 2024 compared to 2023 mainly due to lower funds advanced to Coastal GasLink LP through the subordinated loan agreement.

On December 17, 2024, following the declared commercial in-service of the pipeline, Coastal GasLink LP repaid the &nbsp;&nbsp;&nbsp;&nbsp;$3,147 million balance owing to us under the subordinated loan agreement. Our share of equity contributions required to fund Coastal GasLink LP's repayment of the outstanding loan balance amounted to $3,137 million. The Contributions to equity investments and Other distributions from equity investments with respect to these activities are presented above on a net basis, although they are reported on a gross basis in our Consolidated statement of cash flows. Refer to Note 11, Loans with affiliates, of our 2025 Consolidated financial statements for additional information.

**Other distributions from equity investments**

Other distributions from equity investments decreased in 2025 compared to 2024 mainly due to distributions from Millennium as a result of its debt financing program in 2024, as well as lower return of capital from our equity investment in Iroquois.

Other distributions from equity investments increased in 2024 compared to 2023 mainly due to distributions from Millennium as a result of its debt financing program in 2024.

**Proceeds from sales of assets**

In 2024, TC Energy and its partner, Northern New England Investment Company, Inc., a subsidiary of Énergir, completed the sale of PNGTS to a third party. Our share of the proceeds was $743 million (US$546 million), net of transaction costs.

In 2024, we also completed the sale of other non-core assets for gross proceeds of $48 million.

In 2023, we completed the sale of a 20.1 per cent equity interest in Port Neches Link LLC to its joint venture partner, &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Motiva Enterprises, for gross proceeds of $33 million (US$25 million). As part of the Spinoff Transaction on October 1, 2024, our remaining interest in Port Neches Link LLC was transferred to South Bow.

**Acquisitions**

In 2023, we acquired 100 per cent of the Class B Membership Interests in the Fluvanna Wind Farm located in Scurry County, Texas for US$99 million, before post-closing adjustments. We also acquired 100 per cent of the Class B Membership Interests in the Blue Cloud Wind Farm located in Bailey County, Texas for US$125 million, before post-closing adjustments.

**Loans to affiliate**

In 2023, loans to affiliate (issued) repaid, net, represent issuances and repayments on the subordinated demand revolving credit facility and the subordinated loan agreement that we entered with Coastal GasLink LP to provide additional liquidity and funding to the Coastal GasLink project.

**Notes payable**

Total notes payable outstanding at December 31, 2025 was $1.2 billion (2024 – $387 million).

**Long-term debt and junior subordinated notes**

At December 31, 2025, we had $46.8 billion (2024 – $47.9 billion) of long-term debt and $12.1 billion (2024 – $11.0 billion) of junior subordinated notes.

We attempt to ladder the maturity profile of our debt. The weighted-average maturity of our long-term debt and junior subordinated notes, excluding call features is approximately 19 years.

**Purchase obligations**

We have purchase obligations that are transacted at market prices and in the normal course of business, including long-term natural gas transportation and purchase arrangements.

Capital expenditure commitments include obligations related to the construction of growth projects and are based on the projects proceeding as planned. Changes to these projects, including cancellation, would reduce or possibly eliminate these commitments as a result of cost mitigation efforts.

We have entered into PPAs with solar and wind-power generating facilities ranging from 2026 to 2038, that require the purchase of generated energy and associated environmental attributes. At December 31, 2025, the total planned capacity secured under the PPAs is approximately 750 MW with the generation subject to operating availability and capacity factors. These PPAs do not meet the definition of a lease or derivative. Future payments and their timing cannot be reasonably estimated as they are dependent on when certain underlying facilities are placed in service and the amount of energy generated. Certain of these purchase commitments have offsetting sale PPAs for all or a portion of the related output from the facility.

**GUARANTEES**

**Sur de Texas**

We and our partner on the Sur de Texas pipeline, IEnova Infraestructura Marina Holding B.V. (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. The guarantee has terms that can be renewed in June 2026, with the annual option to extend for one year periods ending in 2053.

At December 31, 2025, our share of potential exposure under the Sur de Texas pipeline guarantees was estimated to be &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;$78 million with a carrying amount of less than $1 million.

**Bruce Power**

We and our 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. The Bruce Power guarantee has a term that can be renewed in December 2027 and is extendable for any number of successive two-year periods, with a final renewal period of three years ending in 2065.

At December 31, 2025, our share of the potential exposure under the Bruce Power guarantee was estimated to be $88 million with no carrying amount.

**Other jointly-owned entities**

We and our partners in certain other jointly-owned entities have also guaranteed (jointly, severally, jointly and severally, or exclusively) the financial performance of these entities. Such agreements include guarantees and letters of credit which are primarily related to delivery of natural gas. The guarantees have terms ranging to 2032.

Our share of the potential exposure under these assurances was estimated at December 31, 2025 to be approximately $54 million with a carrying amount of $1 million. In certain cases, if we make a payment that exceeds our ownership interest, the additional amount must be reimbursed by our partners.

**OBLIGATIONS – PENSION AND OTHER POST-RETIREMENT BENEFIT PLANS**

In 2025, we made no funding contributions to our defined benefit pension plans (DB Plans), $8 million for other post-retirement benefit plans and $72 million for the savings plan and defined contribution plans. Total letters of credit provided for the funding of solvency requirements to the Canadian DB plan at December 31, 2025 was nil (2024 – $111 million; 2023 – $244 million).

In 2026, we do not expect to make any contributions to the DB Plans, $8 million of funding contributions for other post-retirement benefit plans and $76 million for the savings plans and defined contribution pension plans. We do not expect to issue additional letters of credit to the Canadian DB Plan for the funding of solvency requirements.

The net benefit cost for our DB Plans and other post-retirement plans decreased to $11 million in 2025 from $19 million in 2024 primarily due to decrease service costs in the Canadian retirement plan.

**South Bow - transition of pension assets**

As part of the Spinoff Transaction, certain TC Energy employees became employees of South Bow. Prior to the Spinoff Transaction, these employees in Canada and the U.S. participated in DB Plans, DC Plans and savings plans, as applicable. Effective October 1, 2024, the benefit obligations under the DB Plans in respect of the employees moving from TC Energy to South Bow were transferred to South Bow. An asset transfer application related to the Canadian DB Plan outlining the proposed transfer of assets from TC Energy to South Bow has received regulatory approval. During the year ended December 31, 2025, $105 million was transferred to South Bow. As at December 31, 2025, $17 million of assets in the Canadian DB Plan remain in &nbsp;&nbsp;&nbsp;&nbsp;the TC Energy DB Plan trust and are reflected as Current assets of discontinued operations with a corresponding obligation to South Bow reflected as Current liabilities of discontinued operations on our Consolidated balance sheet. The remaining South Bow pension assets will be adjusted to fair value on the date of transfer, which is expected mid-2026. As at &nbsp;&nbsp;&nbsp;&nbsp;December 31, 2024, the assets related to the U.S. DB Plan were fully transferred to South Bow.

86 \| TC Energy **Management's discussion and analysis** 2025

------

Future net benefit costs and the amount we will need to contribute to fund our plans will depend on a range of factors including:

• interest rates

• actual returns on plan assets

• changes to actuarial assumptions and plan design

• actual plan experience versus projections

• amendments to pension plan regulations and legislation.

We do not expect future increases in the level of funding needed to maintain our plans to have a material impact on our liquidity or financial condition.

Discontinued operations

On October 1, 2024, TC Energy completed the spinoff of its Liquids Pipelines business into the new public company, South Bow. Upon completion of the Spinoff Transaction, the Liquids Pipelines business was accounted for as a discontinued operation.

**Agreements**

Pursuant to the Spinoff Transaction, TC Energy and South Bow have executed a series of agreements to outline the parameters and guidelines that govern their ongoing relationship, including a Transition Services Agreement, Tax Matters Agreement and a Separation Agreement.

The Transition Services Agreement was established to specify certain services that TC Energy will provide to South Bow for a period of up to two years.

The Tax Matters Agreement imposes certain restrictions on both TC Energy and South Bow in order to preserve the tax-free status of the spinoff and allocates tax liabilities in the event the Spinoff Transaction is not tax-free.

The Separation Agreement sets forth the terms of the separation of the Liquids Pipelines business from the business of TC Energy, including the transfer of certain assets related to the Liquids Pipelines business from TC Energy to South Bow and the allocation of certain liabilities and obligations related to the Liquids Pipelines business between TC Energy and South Bow.

In September 2025, we reached an agreement with South Bow with respect to liabilities we indemnified South Bow for under the Separation Agreement, releasing us from those liabilities. Inclusive of the recognition of the settlement, a net after-tax loss from discontinued operations of $183 million was recorded for the year ended December 31, 2025 and has been excluded from our calculation of comparable measures from discontinued operations. Payments related to the settlement commenced in fourth quarter 2025 and will be completed in 2026.

In June 2025, we received $24 million related to certain recoveries under the Separation Agreement with South Bow. At this time, we also revised our estimate of our share of future recoveries, resulting in a $29 million impairment charge, which has been included in Net income (loss) from discontinued operations, net of tax in the Consolidated statement of income and excluded from our calculation of comparable measures from discontinued operations.

For additional information regarding the agreement, incidents occurring prior to the Spinoff Transaction and separation costs, refer to Note 4, Discontinued operations, of our 2025 Consolidated financial statements and our 2024 Annual Report.

**Presentation of Discontinued Operations**

Upon completion of the Spinoff Transaction, the Liquids Pipelines business was accounted for as discontinued operations. Our presentation of discontinued operations includes revenues and expenses directly attributable to the Liquids Pipelines business.

Prior years' amounts present the Liquids Pipelines business as discontinued operations.

**RISK OVERSIGHT AND ENTERPRISE RISK MANAGEMENT**

Risk management is embedded in all activities at TC Energy and is integral to the successful operation of our business. Our strategy ensures that risks and related exposures are aligned with our business objectives and risk tolerances. We achieve this through a centralized Enterprise Risk Management (ERM) program, which systematically identifies and assesses risks that could materially impact our strategic objectives.

The ERM program addresses risks related to executing our business strategies and supports practices for identifying and monitoring emerging risks. Specifically, the ERM framework offers a comprehensive process for risk identification, analysis, evaluation and mitigation. It also ensures ongoing monitoring and reporting to the Board of Directors, CEO, Executive &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Vice-Presidents and the Chief Risk Officer.

**Board and Committee Oversight**

Our Board of Directors retains general oversight over all enterprise risks. Annually, the Board reviews the enterprise risk register and receives quarterly updates on emerging risks and their management and mitigation in accordance with TC Energy's risk appetite and tolerances. Additionally, the Board receives detailed presentations on enterprise risks quarterly, with specific themes addressed during regular financial updates and strategic meetings. Special presentations are also delivered as needed or upon request.

The Governance Committee of our Board oversees the ERM program, ensuring comprehensive oversight of our risk management activities. In addition, other Board committees oversee specific risk types within their mandates:

• the Human Resources Committee oversees executive resourcing, organizational capabilities and compensation risk to ensure human and labour policies and remuneration practices align with our overall business strategy

• the HSSE Committee oversees operational, major project execution, health, safety, sustainability and environmental risks, including climate-related risks

• the Audit Committee oversees management's role in mitigating financial risk, including market risk, insurance risk, counterparty credit risk and cybersecurity risk.

**Executive Leadership and Risk Management**

Our Executive Leadership team is responsible for developing and implementing risk management plans and actions, with effective risk management reflected in their compensation. Each identified enterprise risk has a governance owner from the executive leadership team. Risk execution is overseen by an accountable business unit President or Senior Vice-President. These risk owners provide in-depth risk reviews to the Board annually.

**Segment-Specific Risks**

Key segment-specific financial, health, safety and environment-related risks are covered in their respective sections of this MD&A. Further, our Report on Sustainability provides information on our approach to sustainability, including the oversight of sustainability-related risks and opportunities.

**Enterprise Risk Monitoring and Key Risk Indicators**

Risks related to our key enterprise risk themes are continuously monitored through our ERM program. The program includes a network of emerging risk liaisons strategically positioned across the organization, responsible for identifying potential enterprise-level risks and reporting them quarterly to the Board of Directors.

Additionally, as part of our ongoing commitment to enhancing the ERM program, we employ Key Risk and Performance Indicators (KRIs) to monitor risk events that could impact our strategic objectives. These KRIs provide quantifiable metrics, objective rationale and meaningful trends for each enterprise risk, helping to inform the annual in-depth review of enterprise risks conducted by the Board.

**Operational risk**

Across North America, TC Energy manages a vast natural gas transmission network that includes numerous facilities, gas storage reservoirs and power-generation plants. Operational risks include the potential for significant ruptures or failures, especially in regions where pipelines traverse populated areas. Key factors contributing to these risks include integrity threats such as corrosion, cracking and manufacturing defects and third-party damage. Additionally, aging infrastructure and the potential for extreme weather conditions and other external forces further increase the likelihood of significant ruptures or operational failures.

The consequences of a significant rupture or operational failure can be severe and multifaceted. Potential impacts include loss of human life or severe injuries, environmental damage and extensive operational disruptions. Financial repercussions are also considerable, encompassing costs related to incident response, repairs, fines and penalties. Furthermore, such incidents can lead to incremental regulatory enforcement and reputational harm, which may strain customer relationships and jeopardize future projects.

To ensure the safe and reliable operation of its assets, TC Energy employs a robust Operational Management System, TOMS, that integrates comprehensive risk management and asset integrity practices. Current measures include a quantitative operational risk assessment process, integrity management programs and advanced inline inspection technologies. We also conduct failure investigations and root cause analyses to drive continuous improvement. Governance and oversight by senior management, along with an Emergency Management Program, ensure preparedness and effective response to potential incidents. TOMS standards, processes and procedures are continually improved based on lessons learned from internal and external incidents, as well as collaborative work with industry peers and regulators.

**Regulatory risk**

TC Energy operates in a highly regulated industry across North America, requiring various permits and approvals from federal, state, provincial and local government agencies. The regulatory landscape is highly complex, with overlapping and sometimes conflicting requirements from various levels of government. Changes in government can further introduce uncertainty and delays in obtaining necessary permits. Additionally, opposition groups can influence regulatory decisions through organized protests, legal challenges and negative media campaigns.

Failure to obtain or maintain regulatory approvals for energy infrastructure projects can lead to substantial financial and operational consequences. These include delays or cancellations of critical projects, increased operating costs due to additional compliance requirements and disruptions to existing infrastructure. Financial impacts also encompass lost development costs, reduced investor confidence and higher capital costs. Moreover, negative publicity and public opposition can damage our reputation, erode public trust and hinder our ability to operate effectively. These challenges can ultimately affect our competitive position and ability to meet growth objectives.

To address this risk, we have implemented several monitoring and mitigation strategies. These include proactive efforts to monitor the evolving regulatory environment, engage in strategic advocacy across all levels of government, cultivate enduring trust and alignment with stakeholders and respond promptly to emerging issues and concerns. These activities are designed to secure necessary approvals to support our growth objectives and mitigate potential delays and disruptions.

**Access to capital at a competitive cost**

We require significant capital in the form of debt and equity to finance our growth projects and manage maturing debt obligations. It is essential that we secure this capital at costs lower than the returns on our investments. Deterioration in market conditions, changes in investor and lender sentiment, geopolitical instability, higher interest rates and persistent inflation could adversely affect our access to and cost of capital. Additionally, factors such as investor ESG exclusionary screening, capacity limitations in capital markets and economic uncertainties can further compound these risks, potentially leading to higher borrowing costs and constrained growth.

A higher cost of capital can negatively impact our ability to deliver attractive returns on investments and inhibit both<br>short- and long-term growth. This could adversely affect our earnings and undermine the viability of capital projects. Additionally, higher costs can negatively impact investor confidence, the reported value of assets and liabilities and our overall financial performance.

TC Energy **Management's discussion and analysis** 2025 \| 95

------

TC Energy employs a comprehensive strategy to monitor and mitigate these risks. Current mitigations include maintaining a high-quality and diversified banking syndicate, proactive engagement with lenders and credit rating agencies and balancing issuance strategies across multiple capital markets. We also actively manage our foreign exchange risk through hedging strategies and maintain a balanced debt portfolio to manage interest rate exposure. Ongoing mitigations involve developing new lending relationships and enhancing engagement with ESG-focused investors. Additionally, TC Energy continuously monitors government policies and industry developments to proactively address potential influences on capital flows.

**Capital allocation**

To remain competitive, TC Energy must provide essential energy infrastructure services in both supply and demand areas, offering solutions that appeal to our customers, while maintaining alignment with our strategic objectives. Capital allocation challenges include balancing investments to defend our existing footprint and service our customer base, investing in the highest-return, lowest-risk opportunities within our discretionary annual net capital limit and shaping the capital program to optimally utilize available capital.

Inefficient capital allocation can lead to the misallocation of financial resources to projects that do not align with our strategic objectives, increase exposure to high-risk projects and reduce financial performance. Additionally, failure to adapt to changing energy supply and demand fundamentals, including those related to lower-carbon forms of energy, may result in reputational damage, regulatory risks and the potential for stranded assets. Diversifying capital into emerging or alternative energy businesses before technologies, commercial models, and regulatory frameworks have matured also poses risk. Overall, these risks can cause strategic misalignment and diminish shareholder value.

We have a rigorous governance process to maintain capital allocation discipline. We limit annual net capital expenditures and high-grade our project development pipeline for purposes of pursuing lower risk and higher value opportunities. We also conduct analyses to confirm the resilience of the supply and demand markets we serve as part of our strategic reviews and regularly monitor industry trends and regulatory developments. Continuous improvements to the capital allocation process include enhanced investment review and due diligence, as well as conducting long-term scenario analyses to understand the portfolio effects of capital allocation choices.

**Capital recovery risk**

Capital recovery risk pertains to the challenge of both earning an acceptable return on invested capital and recovering the initial investment. This risk arises from potential misalignment between deal structures and our risk preferences, leading to capital exposure. Key contributors include inadequate risk assessments, difficulties in stakeholder collaboration, unforeseen changes in project scope or environment, financial constraints, macroeconomic volatility, counterparty risk, regulatory risk and evolving public policy. Collectively, these factors threaten our financial stability and strategic objectives.

The inability to recover a return on capital can lead to unexpected capital expenditures, significant financial losses and reduced returns. It can erode trust and credibility with partners, investors, regulators and other key stakeholders. Additionally, poorly structured deals may divert management's focus from core business activities to address arising issues, further impacting operational efficiency. The broader consequences include potential damage to our reputation and investor confidence, which are crucial for sustaining long-term growth and stability and preserving shareholder value.

TC Energy employs a robust due diligence process that includes comprehensive risk assessments and detailed contract negotiations. Continuous monitoring of risk exposures and mitigation measures is conducted throughout the lifecycle of each deal, high-grading our project development pipeline to the lowest-risk, highest-value opportunities. Proactive engagement with counterparties and strategic partnerships helps manage and share risks effectively. Depreciation is recovered through regulated pipeline rates, allowing us to accelerate or decelerate the return of capital from our assets. Additionally, we leverage our diversified asset base and long-term contracts to stabilize cash flows and reduce exposure to market volatility.

96 \| TC Energy **Management's discussion and analysis** 2025

------

**Project execution**

Investing in large infrastructure projects requires significant capital commitments and carries considerable project execution risks. Potential shortages of skilled labour and expertise, supply chain lead times and disruptions and increasing project and regulatory complexity are among these risks. Collectively, these factors can lead to cost overruns, schedule delays, suboptimal project performance and increased safety vulnerabilities, ultimately impacting our financial performance, reputation and strategic growth.

Failure to effectively manage these risks can result in significant financial and operational consequences. Cost overruns and schedule delays can undermine the profitability and feasibility of projects, leading to increased contractual claims and disputes. Additionally, inadequate project execution can damage our reputation, reduce investor confidence and hinder future growth opportunities.

To help mitigate these risks, our Project Delivery System is integrated with our capital allocation process and is aligned with TOMS, optimizing project execution for safe, timely and on-budget performance. We develop projects to a sufficient maturity level to fully understand scope, cost, schedule and execution risk prior to sanctioning. This approach enables us to identify and consult stakeholders and proactively address project-specific constraints and risks. Commercial contracts are structured to recover development costs and minimize the impact of potential cost overruns, explicitly sharing execution risk where warranted. Additionally, we leverage project financing and partner involvement to manage capital at risk.

**Talent risk**

TC Energy's success hinges on attracting, retaining and developing a talented workforce with a deep understanding of the energy industry, geopolitical environment and various regulatory regimes across North America. Key talent-related risks include the loss of critical personnel, difficulties in securing and retaining talent in a highly competitive market and health and wellness issues that could impact workforce productivity.

Failure to manage talent-related risk can lead to several adverse outcomes, including a decline in employee morale and engagement, resulting in reduced productivity, efficiency and quality of work. High resignation rates, particularly among top talent, can disrupt operations and continuity, leading to increased recruitment and training costs. The organization may also face reputational damage if perceived as failing to address employee concerns, impacting its ability to attract and retain future talent. Furthermore, operational disruptions and a disengaged workforce can pose health and safety risks, ultimately affecting our overall performance and strategic execution.

To mitigate these risks, TC Energy employs a comprehensive talent risk management framework to assess needs and prioritize initiatives. We focus on employee development, engagement and well-being to foster a positive work environment and retain top talent. Our competitive approach to pay for performance promotes fairness and transparency in compensation practices, while our succession planning process ensures a steady pipeline of talented individuals are prepared to assume critical roles. Regular employee engagement surveys help us translate employee input into meaningful action and improvements. Additionally, we have integrated inclusion and equal opportunity initiatives into our talent management strategies and implemented a hybrid work schedule to offer greater flexibility. Collectively, this approach promotes employee retention, minimizes the impact of potential talent losses and guides targeted development actions.

**Enterprise security**

Ensuring the security of our stakeholders, staff and our assets is paramount to maintaining the safety and reliability of our operations. Security risks encompass potential cyberattacks on industrial control systems and corporate digital assets, unauthorized data disclosures and physical attacks on our infrastructure. These risks are heightened by the increasing sophistication of cyber tactics, rising geopolitical tensions and the critical nature of our business.

A security incident can result in the misuse or disruption of critical information and functions, cause damage to our assets and potentially lead to safety and/or environmental incidents. Resulting service interruptions may have cascading effects on supply chains, customer relationships and strategic goals. Additionally, such incidents can harm our reputation and trigger regulatory enforcement actions or litigation, negatively impacting our operations and/or financial position.

TC Energy **Management's discussion and analysis** 2025 \| 97

------

TC Energy maintains an enterprise security program that encompasses both cyber and physical security. Our program is based on standards, assurance and risk management combining prevention and mitigation activities. Our preventative efforts include deploying advanced security technology, defining secure processes, implementing enhanced security measures for high-risk staff or facilities and delivering cyber and physical security awareness programs. Our mitigative activities include proactive monitoring and response to potential security incidents. We also maintain and regularly test incident response plans to manage and mitigate the impact of potential security incidents, including cyberattacks. To further mitigate potential risks, we maintain insurance coverage against cyber and physical security incidents. To mitigate risks associated with third-party vendors and suppliers, we conduct vendor risk assessments, which includes evaluations of security standards, contractual safeguards and ongoing monitoring.

We collaborate with government security agencies, law enforcement and industry to stay informed and be proactive on evolving threats. Our prevention and mitigation strategies for both cyber and physical security are regularly reviewed and updated to align with regulatory and industry standards. The status of our enterprise security program is reported to the Audit Committee quarterly.

TC Energy remains committed to continually improving our security posture and adapting to the ever-evolving threat landscape. By prioritizing security and investing in technologies and practices, we strive to protect our stakeholders, staff, assets, operations and ensure the long-term sustainability of our business.

**Climate-related risks**

Our business, operations, financial condition and performance may be impacted by both the physical risks associated with climate change and the transition risks arising from the global transition to a lower-carbon economy. Climate-related risks, including changes to climate policy and related developments, may intersect with and influence the enterprise risks outlined above. Therefore, these risks are systematically considered and assessed as part of our risk management framework.

We periodically conduct climate scenario analysis to support our strategic planning and risk management processes. This allows us to assess the resiliency of our business strategy and strengthen our understanding of potential climate-related risks and opportunities across various energy transition pathways. We do not assign probabilities to these scenarios, nor do we consider them to be forecasts or expected outcomes.

**Physical Risks**

Physical climate hazards caused by climate change can be either event-driven (acute), with immediate, severe impacts, or gradual (chronic), resulting from persistent, long-term shifts in climate patterns. The frequency and severity of climate hazards, particularly acute weather events, are difficult to predict. Climate hazards vary greatly across different geographical regions depending on weather patterns, topography and proximity to bodies of water. Many of our natural gas pipeline assets are underground, inherently reducing the exposure to certain types of climate hazards. Exposure to physical climate hazards could have significant financial implications, such as unexpected costs resulting from direct damage to our assets, additional costs for preventative measures, loss of revenues due to business interruption, or indirect effects such as value chain disruption.

If our exposure to climate hazards intensifies, we can implement preventative measures to enhance the resilience of our assets, tailoring these measures to the nature of the hazard and the characteristics of each asset. Additionally, our emergency response plans focus on quickly and effectively responding to severe weather events to minimize impacts. As a further risk mitigation measure, we maintain insurance coverage to reduce the financial impact associated with damage to our assets due to extreme weather events. However, insurance does not cover all events in all circumstances and we may experience an increase in insurance premiums and deductibles, or a decrease in available coverage for our assets in areas subject to severe weather.

**Transition Risks**

Transition risks arise from the global shift toward a lower-carbon economy, and include policy, legal, technological, market and reputational risks. These risks may involve changes in energy supply and demand trajectories, the pace and reliability of technological advancements, changes in decarbonization policies and regulations and stakeholder perceptions of our role in the transition to a lower-carbon economy.

Financial implications could include asset impairments due to new or amended climate-related regulations, reduced demand for fossil fuels, challenges in permitting projects and limited access to and/or increased cost of capital. Our financial performance could also be impacted by shifting consumer demands, insolvency of our significant customers and the development and deployment of new technologies.

98 \| TC Energy **Management's discussion and analysis** 2025

------

In the medium term, these risks would be partially mitigated through our low-risk business model, whereby much of our earnings are underpinned by regulated cost-of-service arrangements and/or long-term contracts with credit-worthy counterparties. Regulators also often permit accelerated depreciation of regulated assets, allowing faster recovery of asset value and helping offset potential terminal value risk if climate policies shorten asset life.

A shift to a lower-carbon economy could also present substantial investment opportunities in emerging energy markets and technologies. Our existing capabilities in lower-carbon energy generation, including nuclear power and energy storage technologies, could enable us to capitalize on new lower-carbon energy opportunities. Our pipeline network across North America also provides an extensive footprint of linear infrastructure that could be leveraged to transport emerging clean fuels like hydrogen and renewable natural gas, as well as to facilitate the transportation of captured carbon emissions for sequestration.

Additional information on our climate strategy and climate-related risks and opportunities can be found in the climate-related disclosures section of our annual Report on Sustainability.

**Health, safety, sustainability and environmental matters**

The Board's HSSE Committee oversees operational risk, major project execution risk, occupational and process safety, sustainability, security of personnel, environmental and climate change-related risks, as well as monitoring development and implementation of systems, programs and policies relating to HSSE matters through regular reporting from management. &nbsp;&nbsp;&nbsp;&nbsp;We use an integrated management system that establishes a framework for managing these risks and is used to capture, organize, document, monitor and improve our related policies, standards and procedures.

TC Energy's Operational Management System, TOMS, leverages industry best practices and standards and incorporates applicable regulatory requirements. TOMS governs health, safety, environment and operational integrity matters at TC Energy. It is applicable across Canada, the U.S. and Mexico throughout the lifecycle of our assets and employs a continuous improvement cycle. The TOMS framework leverages continuous improvement through an annual management review process. This ensures the ongoing effectiveness of our overarching management system and supports a tiered assurance structure across all business units. The TC Energy assurance model is designed to provide effective management of health, safety, environmental and operational integrity risks. Lessons learned are consistently shared and applied across our system where applicable. Additionally, any findings or insights from periodic audits conducted by our external regulators are also shared across the elements of our management system to ensure continuous improvement.

The HSSE Committee reviews performance and operational risk management. It receives updates and reports on:

• overall HSSE corporate governance

• operational performance

• asset integrity

• significant occupational safety and process safety incidents

• occupational and process safety performance metrics

• occupational health, safety and industrial hygiene, which includes physical and mental health, as well as psychological safety

• emergency preparedness, incident response and evaluation

• environment, including biodiversity and land reclamation

• developments in and compliance with, applicable legislation and regulations, including those related to climate and the environment

• prevention, mitigation and management of risks related to HSSE matters, including climate policy or business interruption risks, such as pandemics, which may adversely impact TC Energy

• sustainability matters, including social, environmental and climate-related risks and opportunities, as well as related &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;non-regulatory public disclosures such as our annual Report on Sustainability, our Reconciliation Action Plan and updates on the progression of our commitments.

There are two separate committees that report to the Board HSSE Committee:

• a Sustainability Management Committee, comprised of senior leaders and heads of business units from across the company, that provides strategic direction on sustainability-related matters and fosters cross-functional collaboration across the organization

• Safety and TOMS Advisory Committee (STAC), comprised of senior project and operations leaders, oversees governance and decision-making for TOMS and safety initiatives, while assuming an enterprise-wide role to oversee and guide health, safety, environment and operational integrity. In 2025, governance accountability transitioned from the Operating Committee to the relevant business leadership teams, business unit-specific operating committees and STAC.

**Health, safety and asset integrity**

The safety of our employees, contractors and the public, the integrity of our pipelines and our power and energy solutions infrastructure, are a top priority. All assets are designed, constructed, commissioned, operated and maintained with full consideration given to safety and integrity and are placed in service only after all necessary requirements, both regulatory and internal, have been satisfied.

In 2025, we spent approximately $2.0 billion (2024 – $2.0 billion) for pipeline integrity on the natural gas pipelines we operate, which includes expenditures related to our modernization program within our U.S. Natural Gas Pipelines business. Pipeline integrity spending will fluctuate based on the results of on-going risk assessments conducted on our pipeline systems and evaluations of information obtained from recent inspections, incidents and maintenance activities.

Under the approved regulatory models in Canada, non-capital pipeline integrity expenditures on CER-regulated natural gas pipelines are generally treated on a flow-through basis and, as a result, fluctuations in these expenditures generally have no impact on our earnings. Non-capital pipeline integrity expenditures on our U.S. natural gas pipelines are primarily treated as operations and maintenance expenditures and are typically recoverable through tolls approved by FERC. Under regulatory rules in Mexico, non-capital pipeline integrity expenditures and those under lease accounting are treated primarily as operating and maintenance expenses and are generally recovered through our tolls.

Spending associated with process safety and integrity is used to minimize risk to employees, contractors, the public, equipment and the surrounding environment and also prevent disruptions to serving the energy needs of our customers.

As described in the Risk oversight and enterprise risk management section above, we have a set of procedures in place to manage our response to natural disasters, which include catastrophic events such as forest fires, tornadoes, earthquakes, floods, volcanic eruptions and hurricanes. The procedures, which are included in our Emergency, Business Continuity and Security element of TOMS, are designed to help protect the health and safety of our employees and contractors, minimize risk to the public and limit the potential for adverse effects on the environment. We are committed to protecting the health and safety of all individuals involved in our activities. Occupational health, safety and industrial hygiene provides comprehensive strategies for health promotion and protection. We are committed to delivering effective programs that:

• reduce the human and financial impact of illness and injury

• ensure fitness for work

• strengthen worker resiliency

• build organizational capacity by focusing on individual wellbeing, health education, leader support and improved working conditions to sustain a productive workforce

• increase mental wellbeing awareness, provide various health and wellness supports and training to employees and leaders, measure the success of programs and improve psychological safety

• foster a strong safety culture by building human and organizational performance to strengthen our cultural defenses and develop error-tolerant systems to better protect our people.

**Environmental risk, compliance and liabilities**

Through the implementation of TOMS, TC Energy proactively and systematically manages environmental hazards and risks throughout the lifecycle of our assets. Project plans are communicated with stakeholders and Indigenous communities, as applicable and engagement with these groups informs the environmental assessments and protection plans. Project environmental assessments include field studies that examine existing natural resources, biodiversity and land use along our proposed project footprint, such as vegetation, soils, wildlife, water resources, wetland and protected areas. We consider the information collected during environmental assessments and where sensitive habitats or areas of high biodiversity value are identified, we apply the biodiversity mitigation hierarchy and avoid those areas, as practicable. Where those areas cannot be avoided, we minimize our disturbance, restore and reclaim the disturbed area and provide offsets where required. To conserve and protect the environment during construction, information gathered for an environmental impact assessment is used to develop project-specific environmental protection plans. Whenever the potential exists for a proposed facility or pipeline to interact with water resources, we conduct evaluations to understand the full nature and extent of the interactions. When we temporarily use water to test the integrity of our pipelines, we adhere to strict regulatory requirements and ensure water meets applicable water quality standards before it is discharged or disposed of and when our construction activities involve crossing waterbodies, we implement protection measures to avoid or minimize potential adverse effects.

TC Energy **Management's discussion and analysis** 2025 \| 101

Our primary sources of risk related to the environment include:

• evolving regulations and compliance requirements, alongside rising costs associated with environmental impacts

• product releases with potential environmental impact

• use, storage and disposal of chemicals and hazardous materials

• natural disasters and other catastrophic events, including those related to climate change, which may impact our operations.

Our assets are subject to federal, state, provincial and local environmental statutes and regulations governing environmental protection, including air and GHG emissions, water quality, species at risk, wastewater discharges and waste management. Operating our assets requires obtaining and complying with a wide variety of environmental registrations, licenses, permits and other approvals and requirements. Failure to comply could result in administrative, civil or criminal penalties, remedial requirements, or orders affecting future operations.

TOMS includes requirements for us to continually monitor our facilities for compliance with all material legal and regulatory environmental requirements across all jurisdictions where we operate. We also comply with all material legal and regulatory permitting requirements in our project routing and development. We routinely monitor proposed changes to environmental policy, legislation and regulation. Where the risks are uncertain or have the potential to affect our ability to effectively operate our business, we comment on proposals independently or through industry associations.

We are not aware of any material outstanding orders, claims or lawsuits against us related to releasing or discharging any material into the environment.

Compliance obligations can result in significant costs associated with installing and maintaining pollution controls, fines and penalties resulting from any failure to comply and potential limitations on operations. Remediation obligations can result in significant costs associated with the investigation and remediation of contaminated properties and with damage claims arising from the contamination of properties.

The timing and complete extent of future expenditures related to environmental matters is difficult to estimate <br>accurately because:

• environmental laws and regulations and their interpretations and enforcement change

• new claims can be brought against our existing or discontinued assets

• our pollution control and clean-up cost estimates may change, especially when our current estimates are based on preliminary site investigations or agreements

• new contaminated sites may be found or what we know about existing sites could change

• where there is potentially more than one responsible party involved in litigation, we cannot estimate our joint and several liability with certainty.

At December 31, 2025, accruals related to these obligations totaled $6 million (2024 – $8 million) representing the estimated amount we will need to manage our currently known material environmental liabilities. We believe we have considered all necessary contingencies and established appropriate reserves for environmental liabilities; however, a risk exists that unforeseen matters may arise requiring us to set aside additional amounts. We adjust reserves regularly to account for changes in liabilities.

**Climate policy and related regulation** 

We own assets and have business interests in a number of regions subject to GHG emissions regulations, including GHG emissions management and carbon pricing policies. In 2025, we incurred $194 million (2024 – $141 million) of expenses under existing carbon pricing programs. Across North America, there are a variety of new and evolving climate policy developments at the federal, regional, state and provincial levels. We actively monitor, participate in the regulatory review process as appropriate and submit formal comments to regulators as initiatives are undertaken and as policies are implemented. We support transparent, investment-conducive climate policies that promote environmentally and economically responsible natural resource development through market-driven and economically efficient outcomes. Our assets in certain geographies are currently subject to GHG regulations. While near-term government policy objectives may influence the pace of GHG regulations, we expect that the number of our assets subject to GHG regulations will continue to increase over time and across our footprint. Changes in regulations may often result in higher operating costs, other expenses or capital expenditures, which are generally recoverable through established cost-recovery mechanisms.

**Jurisdictional policies** 

This section describes the most relevant existing and emerging policies affecting our business, emphasizing legislative and regulatory impacts.

In the U.S., we have seen significant policy shifts under the current administration. In January 2025, several Executive Orders directed agency heads to use all available legal authority to enhance U.S. energy production, transportation and consumption, and to focus on energy production and utilization ("energy dominance"). Additionally, in March 2025, the U.S. Environmental Protection Agency (USEPA) outlined a list of plans, including changes to some USEPA programs, and the intent for administrative reconsideration of many rules promulgated under the previous administration that have now started to advance through the regulatory process. Substantial uncertainty exists with respect to future implementation of these rules and the scope of the USEPA's jurisdiction more generally. Depending upon the outcome of certain rulemakings and associated litigation challenging new rules, TC Energy could face increased project delays. We continue to monitor these potential regulatory changes to determine our compliance obligations and potential costs.

***Existing policies***

• **Carbon pricing policies** (*multi-jurisdictional*): While carbon pricing exists in several jurisdictions where we operate, its applicability to our assets and associated compliance costs vary substantially. Carbon pricing policies with significant impact on our business include the following:

&nbsp;&nbsp;&nbsp;&nbsp;◦ Canada – Alberta's Technology Innovation and Emissions Reduction (TIER) program represents our largest compliance costs in Canada. For our regulated Canadian natural gas pipelines within the province, we recover these costs through tolls. For our Power and Energy Solutions assets, we recover a portion of these costs through market pricing and hedging activities

&nbsp;&nbsp;&nbsp;&nbsp;◦ U.S. – certain GTN compressor facilities are subject to the Washington Cap-and-Invest Program. GTN's compliance costs are driven by total facility emissions, and GTN is authorized to recover these costs through its rates over time

• **Clean Electricity Regulations** (*Canada*): In 2024, Environment and Climate Change Canada (ECCC) published the final Clean Electricity Regulations (CERs) to transition Canada's electricity system to net-zero electricity by 2050. The CERs mandate an annual GHG emissions limit based on 65 tonnes CO2/GWh for fossil fuel power generation units with a capacity of 25 MW or more starting in 2035 and zero tonnes CO2/GWh in 2050. Concerns persist on the CERs' potential effect on energy affordability and reliability in certain provinces given the regulations limited compliance flexibilities. We continue to evaluate the operational and financial impact on TC Energy cogeneration plants. The Canada-Alberta Memorandum of Understanding (MOU), signed in November 2025, signals the CERs would be suspended in Alberta pending a new carbon pricing agreement. &nbsp;&nbsp;&nbsp;&nbsp;If a regulatory exemption is reached for the province, this would remove the requirement to comply with the CERs for most of TC Energy's cogeneration facilities

• **Endangerment Finding** (*U.S.*): In July 2025, the USEPA released a proposal to rescind the 2009 Endangerment Finding &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(the Finding), which found that GHG emissions pose a threat to public health and welfare. The Finding has been the basis for subsequent GHG regulations. While rescinding the Finding would not automatically invalidate existing GHG regulations for the oil and gas sector, the USEPA has indicated that it plans to separately review related current standards. TC Energy has consistently complied with various regulations stemming from the Finding. We continue to monitor the USEPA's proposed regulatory changes; however, the impacts of these proposed changes cannot be determined at this time

• **Greenhouse Gas Reporting Program (GHGRP)** (*U.S.*): In 2024, the USEPA finalized changes to the GHGRP for how oil and gas sources tally and report their methane emissions (Subpart W). These changes add new reporting sources, modify calculation and reporting methodologies, and drive more granular data collection. Subsequently, in September 2025, USEPA issued a draft rule that announced it found no obligation under the Clean Air Act to collect GHG data and no statutory benefit. In the proposal, USEPA proposes to eliminate reporting obligations for all GHGRP subparts, except Subpart W (non-combustion GHG emissions from the Petroleum & Natural Gas Systems), which would be suspended until the Reporting Year 2034. The potential elimination or significant overhaul of the GHGRP could potentially have indirect implications for state-level reporting frameworks, voluntary industry reporting and compliance strategies and overall transparency of emissions data. Certain states may elect to implement GHG reporting programs in the absence of a federal framework, which could increase administrative burden and complicate cross-jurisdictional reporting for our industry. TC Energy supported industry group comments advocating for retention of the GHGRP. Additionally, in November 2024, USEPA finalized its rule to implement the Inflation Reduction Act's Waste Emission Charge, which would apply a fee to certain oil and gas facilities that report methane emissions of more than 25,000 metric tons of carbon dioxide equivalent per year to the GHGRP. However, in March 2025, Congress prohibited USEPA from collecting the Waste Emissions Charge until 2034. As a result of the pending changes to the GHGRP, substantial uncertainty exists with respect to future implementation of the Waste Emissions Charge

• **Good Neighbor Rule** (*U.S.*): The USEPA "Good Neighbor Rule" (the Rule) as finalized in March 2023, set new limits for emissions of nitrogen oxides (NOx) from reciprocating internal combustion engines by May 2026. The Rule was stayed in its entirety by the U.S. Supreme Court in June 2024 pending a complete review by the U.S. Circuit Court of Appeals for the D.C. Circuit (the "D.C. Circuit Court"). In March 2025, the USEPA Administrator announced the intention to reconsider numerous pending, proposed and final rules and policies, including "ending" the Rule. The USEPA subsequently stated it plans to reconsider the Rule and conduct a new rulemaking process in 2026. As a result, the D.C. Circuit has placed the litigation challenging the existing Rule in abeyance to allow the USEPA to reconsider and propose the new rule. On January 28, 2026, the USEPA announced the first of a two-step plan to reconsider the Rule, issuing a proposal to reverse prior State Implementation Plan disapprovals in the eight states that were subject to the Rule. If finalized as proposed, the Rule would no longer apply in several states where TC Energy operates assets subject to the Rule. The USEPA indicated that it will take secondary action in the near term to address the states that remain subject to the Rule. We continue to monitor and assess the USEPA's proposed regulatory changes

• **Methane-specific regulations** (*multi-jurisdictional*): In all three countries where TC Energy operates, there are regulations to reduce methane emissions from the oil and gas industry. Though requirements vary by jurisdiction, they generally focus on eliminating fugitive emissions through leak detection and repair programs and reducing vented emissions from equipment. The regulations in each country is discussed below:

&nbsp;&nbsp;&nbsp;&nbsp;◦ Canada – The ECCC Regulations Respecting Reduction in the Release of Methane and Certain Volatile Organic Compounds took effect in 2020 and aimed to reduce the oil and gas sector's methane emission by 40 to 45 per cent below 2012 levels by 2025. Several provinces enacted their own methane regulations that took the place of the federal regulations for provincially regulated assets through equivalency agreements. Our Canadian natural gas pipeline assets are subject to either the federal or British Columbia requirements, while our Alberta natural gas storage assets are subject to the Alberta requirements. In December 2025, ECCC published amendments to strengthen these regulations. This is part of Canada's newest commitment to reduce the oil and gas sector methane emissions by at least 75 per cent below 2012 levels by 2030. The amendments introduce a risk-based approach for the detection and repair of fugitive emissions, prohibit all venting with specific exceptions, and offer an alternative performance-based approach using continuous monitoring. The amendments take effect on January 1, 2028, with phased requirements through 2030. While our Canadian natural gas pipeline assets have a mature leak detection and repair program and vent management approach to meet current regulations, compliance with these amendments will impose additional costs to our operations. We will continue to refine our internal emissions management strategies and update our compliance plans for our Canadian natural gas pipeline assets to align with the regulatory changes

&nbsp;&nbsp;&nbsp;&nbsp;◦ U.S. – In 2023, the USEPA finalized a rule that amended and supplemented the New Source Performance Standards – Subpart OOOO series of volatile organic compound and methane emissions regulations for the oil and natural gas industry. The rule, collectively referred to as the "Methane Rule," set performance standards for new, modified, or reconstructed sources after December 6, 2022 (OOOOb) and established emission guidelines (EGs) for existing sources prior to December 6, 2022 (OOOOc). Affected U.S. natural gas compressor stations would be required to comply with the Methane Rule, and the costs of compliance are anticipated to be incorporated into new and modified facilities moving forward. The OOOOc standards would apply to a larger number of existing facilities, but impacts will be subject to the requirements of state EG proposals and actual compliance deadlines, which will vary based on state and/or location and have not yet been issued. In July 2025, USEPA issued an interim final rule (IFR) that extends several compliance deadlines under both OOOOb and OOOOc. The IFR also indicates that the USEPA may introduce further substantive changes to the Methane Rule through a separate reconsideration process. These extensions give operators and states more practical timelines for associated implementation and planning but also provide USEPA with time to proceed with announced plans for reconsideration of the Methane Rule. Certain states, such as New York, Pennsylvania, Maryland and California, have independently enacted their own methane emissions regulations. TC Energy is closely monitoring these developments as applicable to our business

&nbsp;&nbsp;&nbsp;&nbsp;◦ Mexico – In 2018, the Agencia de Seguridad, Energía y Ambiente (ASEA) released the Guidelines for the Prevention and Control of Methane Emissions from the Hydrocarbon Sector to reduce the sector's methane emissions by 40 to 45 per cent by 2025. Per the guidelines' requirements, TC Energy developed and has implemented a Program for the Comprehensive Prevention and Control of Methane Emissions (PPCIEM) for our Mexican facilities since 2020

104 \| TC Energy **Management's discussion and analysis** 2025

------

• **Onshore Natural Gas Pipelines Standard** (*Mexico*): In September 2025, ASEA replaced NOM-007-ASEA-2016 with &nbsp;&nbsp;&nbsp;&nbsp;NOM-020-ASEA-2024 to regulate the design, construction, operation and maintenance of onshore natural gas transmission pipelines. The standard, which will take effect February 28, 2026, adds incremental requirements with respect to operations, maintenance, inspections, documentation and audits to renew and maintain permits. We are currently updating our pipeline design and construction processes accordingly. We do not anticipate this standard to have a material impact on our business in Mexico

• **Sustainability-related disclosure requirements** (*multi-jurisdictional*): Various sustainability disclosure requirements (including climate-related topics) are being issued in jurisdictions in which we operate. We continue to monitor these developments and progress our sustainability-related disclosures to reflect new and anticipated requirements. Our enterprise-wide sustainability-related disclosures, including a dedicated Climate-related disclosures section, can be found in our annual Report on Sustainability

&nbsp;&nbsp;&nbsp;&nbsp;◦ U.S. – California's senate bill (SB) -253 and SB-261 require certain U.S. companies doing business in California to disclose their GHG emissions and climate-related financial risks, respectively. Entities within the scope of SB-261 must prepare a climate-related financial risk report by January 1, 2026; however, enforcement of SB-261 has been halted while litigation is ongoing in federal court. Applicability to TC Energy is under evaluation

&nbsp;&nbsp;&nbsp;&nbsp;◦ Mexico – the Normas de Información de Sostenibilidad (NIS) requires the disclosure of 30 sustainability indicators across environmental, social and governance topics for fiscal years beginning on or after January 1, 2025. These requirements will apply to certain TC Energy Mexican entities as part of compliance with financial standards.

***Anticipated policies***

• **Carbon Pricing** (*Canada*): In December 2025, ECCC released a discussion paper on potential updates to strengthen the federal carbon pricing benchmark on industrial emissions, which sets the minimum requirements for provincial systems. In general, these systems require regulated facilities to reduce their emissions below an intensity baseline which leads to credit generation or compliance obligations. The proposed updates include changes to coverage and scope, certain compliance pathways and public reporting requirements. They are intended to ensure industrial carbon pricing systems are more consistent, efficient and effective across the country. TC Energy currently operates under several carbon pricing systems subject to the federal backstop. We will monitor these developments, evaluate potential impacts and engage with ECCC, as appropriate

• **New Energy Policy Considerations** (*Mexico*): In late 2025, Mexico published the New Energy Policy Considerations as part of its broader energy policy framework, which includes the Energy Sector Program 2025-2030 (PROSENER) and other official documents. The energy policy framework influences the country's implementation of climate policies, long-term view of natural gas, and integration of social objectives. It also signals the development of additional regulations. PROSENER specifically proposes additional emission reductions (including methane) through greater energy efficiency, technological innovation, and the construction and modernization of new energy infrastructure. We will continue monitoring these policy developments and provide feedback to the respective government departments, as appropriate

• **Oil and Gas Emissions Cap** (*Canada*): In 2024, ECCC published the draft Oil and Gas Sector Greenhouse Gas Emissions Cap Regulations. The draft regulations introduce a cap-and-trade system as of 2030 to reduce GHG emissions from the oil and gas sector, covering upstream activities and LNG production. Although transmission pipelines are excluded from the draft regulations, there is a possibility of cascading effects and unintended consequences to our Canadian natural gas pipelines business. The draft regulations were set to be finalized in 2025, but under the Canada-Alberta MOU signed in November 2025, the Government of Canada has committed to not implementing them

• **TIER Updates** (*Alberta, Canada*): In December 2025, the Government of Alberta issued an Order in Council introducing an additional compliance pathway that will recognize certain on-site emissions reduction investments for up to 90 per cent of compliance obligations and allowing facilities that are below the regulatory emissions threshold and currently participate in the TIER emission program to opt-out of paying into the TIER fund or retire TIER compliance instruments. The Canada-Alberta MOU signed in November 2025 signals additional changes may be proposed to TIER's carbon price, price escalation, and performance benchmarks. Since these changes are likely to impact the carbon credit market, their effects may have different impacts on our Alberta-based Canadian natural gas pipelines and Power and Energy Solutions assets. We will continue to monitor and evaluate the operational and financial impacts as details of the new carbon pricing agreement with the Government of Canada are made available.

**Financial risks**

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. Our risks are managed within limits that are established by our Board of Directors, implemented by senior management and monitored by our risk management, internal audit and business segment groups. Our Board of Directors' Audit Committee oversees how management monitors compliance with risk management policies and procedures and oversees management's review of the adequacy of the risk management framework.

**Market risk**

We construct and invest in energy infrastructure projects, purchase and sell commodities, issue short- and long-term debt, including amounts in foreign currencies and invest in foreign operations. Certain of these activities expose us to market risk from changes in commodity prices, foreign exchange rates and interest rates, which may affect our earnings, cash flows and the value of our financial assets and liabilities. We assess contracts used to manage market risk to determine whether all, or a portion, meet the definition of a derivative.

Derivative contracts used to assist in managing exposure to market risk may include the following:

• forwards and futures contracts – agreements to purchase or sell a specific financial instrument or commodity at a specified price and date in the future

• swaps – agreements between two parties to exchange streams of payments over time according to specified terms

• options – agreements that convey the right, but not the obligation of the purchaser, to buy or sell a specific amount of a financial instrument or commodity at a fixed price, either at a fixed date or at any time within a specified period.

**Commodity price risk**

The following strategies may be used to manage our exposure to market risk resulting from commodity price risk management activities in our non-regulated businesses:

• in our natural gas marketing business, we enter into natural gas transportation and storage contracts, as well as natural gas purchase and sale agreements. We manage our exposure on these contracts using financial instruments and hedging activities to offset market price volatility

• in our power business, we manage the exposure to fluctuating commodity prices through long-term contracts and hedging activities including selling and purchasing electricity and natural gas in forward markets

• in our non-regulated natural gas storage business, our exposure to seasonal natural gas price spreads is managed with a portfolio of third-party storage capacity contracts and through offsetting purchases and sales of natural gas in forward markets to lock in future positive margins.

Lower natural gas or electricity prices could lead to reduced investment in the development, expansion and production of these commodities. A reduction in the demand for these commodities could negatively impact opportunities to expand our asset base and/or re-contract with our shippers and customers as contractual agreements expire.

**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.

106 \| TC Energy **Management's discussion and analysis** 2025

------

**Foreign exchange risk**

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.

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 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 and cross-currency interest rate swaps 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.

At times, our counterparties may endure financial challenges resulting from commodity price and market volatility, economic instability and political or regulatory changes. In addition to actively monitoring these situations, there are a number of factors that reduce our counterparty credit risk exposure in the event of default, including:

• contractual rights and remedies together with the utilization of contractually-based financial assurances

• current regulatory frameworks governing certain of our operations

• the competitive position of our assets and the demand for our services

• potential recovery of unpaid amounts through bankruptcy and similar proceedings.

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 December 31, 2025 and 2024, we had no significant credit risk concentrations, with the exception of the CFE, which represents approximately 33 per cent of gross exposure. Gross exposure is measured as the unmitigated full-term contract revenue exposure discounted in accordance with each contract's discount rate, as applicable. At this time, there were no significant amounts past due or impaired. We recorded a pre-tax expense of $83 million for the year ended December 31, 2025 on the expected credit loss provision before tax recognized on TGNH net investment in leases and certain contract assets in Mexico (2024 – $22 million recovery). During 2025, we completed the Southeast Gateway pipeline and recognized a net investment in sales-type lease. Other than the expected credit loss provision noted above, we had no significant credit losses at December 31, 2025 and 2024. Refer to Note 27, Risk management and financial instruments, of our 2025 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. Refer to the Financial Condition section for additional information.

**Legal proceedings**

TC Energy and its subsidiaries are subject to various legal proceedings, arbitrations and actions arising in the normal course of business. We assess all legal matters on an ongoing basis, including those of our equity investments to determine if they meet the requirements for disclosure or accrual of a contingent loss. Refer to Note 30, Commitments, contingencies and guarantees, of our 2025 Consolidated financial statements for additional information.

Under the supervision and with the participation of management, including our President and CEO and our CFO, we carried &nbsp;&nbsp;&nbsp;&nbsp;out quarterly evaluations of the effectiveness of our disclosure controls and procedures, including for the year ended &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;December 31, 2025, as required by the Canadian securities regulatory authorities and by the SEC. Based on this evaluation, our President and CEO and our CFO have concluded that the disclosure controls and procedures are effective in that they are designed to ensure that the information we are required to disclose in reports we file with or send to securities regulatory authorities is recorded, processed, summarized and reported accurately within the time periods specified under Canadian and U.S. securities laws.

**Management's report on internal control over financial reporting**

We are responsible for establishing and maintaining adequate internal control over financial reporting, which is a process designed by, or under the supervision of, our President and CEO and our CFO and effected by our Board of Directors, management and other personnel, to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with GAAP.

Under the supervision and with the participation of management, including our President and CEO and our CFO, an evaluation of the effectiveness of the internal control over financial reporting was conducted as of December 31, 2025, based on the criteria described in "Internal Control – Integrated Framework" issued in 2013 by the Committee of Sponsoring Organizations of the Treadway Commission. Based on this assessment, management determined that, as of December 31, 2025, the internal control over financial reporting was effective.

Our internal control over financial reporting as of December 31, 2025 has been audited by KPMG LLP, an independent registered public accounting firm, as stated in their attestation report which is included in our 2025 Consolidated financial statements.

**CEO and CFO certifications**

Our President and CEO and our CFO have attested to the quality of the public disclosure in our fiscal 2025 reports filed with Canadian securities regulators and the SEC and have filed certifications with them.

**Changes in internal control over financial reporting**

There were no changes during the year covered by this annual report that had or are reasonably likely to have a material impact on our internal control over financial reporting.

**CRITICAL ACCOUNTING ESTIMATES**

In preparing our Consolidated financial statements, we are 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. We use the most current information available and exercise careful judgment in making these estimates and assumptions.

Certain estimates and judgments have a material impact where the assumptions underlying these accounting estimates relate to matters that are highly uncertain at the time the estimate or judgment is made or are subjective. Refer to Note 2, Accounting policies, of our 2025 Consolidated financial statements for additional information.

**Sales-type leases**

We determined that the Southeast Gateway pipeline is classified as a sales-type lease between TGNH and the CFE. Under a &nbsp;&nbsp;&nbsp;&nbsp;sales-type lease, we derecognize the underlying asset and record a net investment in lease equal to the present value of both the future lease payments and the estimated residual value of the leased asset.

To record the net investment in lease, we were required to prepare an estimate of the fair value of the Southeast Gateway pipeline on the lease commencement date. The TGNH pipelines, which includes the Southeast Gateway pipeline, are rate-regulated and the tolls are designed to recover the cost of providing service. On this basis, we applied judgment to determine that, at the inception of the lease arrangement, the fair value of the underlying assets approximated the carrying value and the residual value approximated the remaining carrying value at the end of the lease term. We estimated that if the assets were purchased at their carrying value, they would yield a return to the purchaser that is in line with current market participant expectations.

**Impairment of goodwill**

We test goodwill for impairment annually or more frequently if events or changes in circumstances lead us to believe it might be impaired. We can initially assess qualitative factors which include, but are not limited to, macroeconomic conditions, industry and market considerations, cost factors, historical and forecasted financial results, or events specific to that reporting unit. 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. We can elect to proceed directly to the quantitative goodwill impairment test for any reporting unit. If the quantitative goodwill impairment test is performed, we compare the fair value of the reporting unit to its carrying value, including its goodwill. If the carrying value of a reporting unit exceeds its fair value, goodwill impairment is measured at the amount by which the reporting unit's carrying value exceeds its fair value.

When a portion of a reporting unit that constitutes a business is disposed, goodwill associated with that business is included in the carrying amount of the business in determining the gain or loss on disposal. The amount of goodwill disposed is determined based on the relative fair values of the business to be disposed and the portion of the reporting unit that will be retained.

We determine the fair value of a reporting unit based on our projections of future cash flows, which involves making estimates and assumptions about transportation rates, market supply and demand, growth opportunities, output levels, competition from other companies, operating costs, regulatory changes, discount rates and earnings and other multiples.

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.

**Qualitative goodwill impairment indicators**

As part of the annual goodwill impairment assessment at December 31, 2025, we evaluated qualitative factors impacting the &nbsp;&nbsp;&nbsp;&nbsp;fair value of the underlying reporting units for all reporting units other than the Columbia reporting unit, which is described below. It was determined that it was more likely than not that the fair value of these reporting units exceeded their carrying amounts, including goodwill.

**Columbia** 

We elected to proceed directly to a quantitative annual impairment test at December 31, 2025 for the $10,082 million &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(US$7,351 million) of goodwill related to the Columbia reporting unit following the Columbia Gas Settlement. To determine fair value, we used a discounted cash flow model incorporating projections of our future cash flows as well as a valuation multiple and applied a risk-adjusted discount rate which involved significant estimates and judgments. The fair value measurement is classified as Level III in the fair value hierarchy. It was determined that the fair value of the Columbia reporting unit exceeded its carrying value, including goodwill, at December 31, 2025.

**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 rate payers in subsequent years when the derivative settles.

**Balance sheet presentation of derivative instruments**

The balance sheet presentation of the fair value of derivative instruments is as follows:

---

|:---|:---|:---|
| **at December 31** | | |
| (millions of $) | **2025** | **2024** |

**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.

As discussed on page 10 of the About this document section, results of the Liquids Pipelines business were accounted for as a discontinued operation starting October 1, 2024. To allow for a meaningful comparison, discussions throughout the Quarterly results section are based on continuing operations unless otherwise noted. Refer to the Discontinued operations 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.

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

• weather

• customer demand

• newly constructed assets being placed in service

• acquisitions and divestitures

• market prices for natural gas and power

• capacity prices and payments

• power marketing and trading activities

• planned and unplanned plant outages

• developments outside of the normal course of operations

• certain fair value adjustments.

**Factors affecting financial information by quarter**

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. Refer to page 22 for more information on non-GAAP measures we use.

In fourth quarter 2025, comparable earnings from continuing operations also excluded:

• 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 TCPL and 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.

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, of our 2025 Consolidated financial statements 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 <br>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 <br>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 Consolidated statement of income. Refer to Note 19, Long-term debt, of our 2025 Consolidated financial statements 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 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 NGTL Settlement and from Columbia Gas as a result of the Columbia Gas Settlement

• 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 &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;U.S. dollar-denominated income and the revaluation of our peso-denominated net monetary liabilities to U.S. dollars.

**Foreign exchange**

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 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 Consolidated statement of income. Refer to the Financial risks and financial instruments section for additional information.

**Highlights by business segment**

**Canadian Natural Gas Pipelines**

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 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 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.

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 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 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**

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.

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 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 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**

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 <br>peso-denominated liabilities as a result of a stronger Mexican peso and higher income tax expense mainly related to foreign exchange impacts of U.S. dollar-denominated liabilities. Refer to the Sur de Texas results section for additional information.

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 &nbsp;&nbsp;&nbsp;&nbsp;Plant, property and equipment and recorded as a net investment in lease on our Condensed consolidated balance sheet with no depreciation expense being recognized.

**Power and Energy Solutions**

Power and Energy Solutions segmented earnings decreased by $140 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 comparable EBITDA and comparable EBIT:

• 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.

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

**Corporate**

Corporate segmented earnings increased by $17 million for the three months ended December 31, 2025 compared to the same period in 2024. Corporate segmented losses included a pre-tax charge of $9 million for the three months ended December 31, 2024 related to Focus Project costs, which has been excluded from our calculation of comparable EBITDA and comparable EBIT.

Comparable EBITDA and EBIT for Corporate increased by $8 million for the three months ended December 31, 2025 compared to the same period in 2024.

EXHIBIT 13.3

Management's Report on Internal Control over Financial Reporting

The consolidated financial statements and Management's Discussion and Analysis (MD&A) included in this Annual Report are the responsibility of the management of TC Energy Corporation (TC Energy or the Company) and have been approved by the Board of Directors of the Company. The consolidated financial statements have been prepared by management in accordance with United States generally accepted accounting principles (GAAP) and include amounts that are based on estimates and judgments. The MD&A is based on the Company's financial results. It compares the Company's financial and operating performance in 2025 to that in 2024, and highlights significant changes between 2024 and 2023. The MD&A should be read in conjunction with the consolidated financial statements and accompanying notes. Financial information contained elsewhere in this Annual Report is consistent with the consolidated financial statements.

Management is responsible for establishing and maintaining adequate internal control over financial reporting for the Company. Management has designed and maintains a system of internal control over financial reporting, including a program of internal audits to carry out its responsibility. Management believes these controls provide reasonable assurance that financial records are reliable and form a proper basis for the preparation of financial statements. The internal control over financial reporting includes management's communication to employees of policies that govern ethical business conduct.

Under the supervision and with the participation of the President and Chief Executive Officer and the Chief Financial Officer, management conducted an evaluation of the effectiveness of its internal control over financial reporting based on the framework in Internal Control – Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). Management concluded, based on its evaluation, that internal control over financial reporting was effective as of December 31, 2025, to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external reporting purposes.

The Board of Directors is responsible for reviewing and approving the consolidated financial statements and MD&A and ensuring that management fulfills its responsibilities for financial reporting and internal control. The Board of Directors carries out these responsibilities primarily through the Audit Committee, which consists of independent, non-management directors. The Audit Committee meets with management at least four times a year and meets independently with internal and external auditors and as a group to review any significant accounting, internal control and auditing matters in accordance with the terms of the Charter of the Audit Committee, which is set out in the Annual Information Form. The Audit Committee's responsibilities include overseeing management's performance in carrying out its financial reporting responsibilities and reviewing the Annual Report, including the consolidated financial statements and MD&A, before these documents are submitted to the Board of Directors for approval. The internal and independent external auditors have access to the Audit Committee without the requirement to obtain prior management approval.

The Audit Committee approves the terms of engagement of the independent external auditors and reviews the annual audit plan, the Auditors' Report and the results of the audit. It also recommends to the Board of Directors the firm of external auditors to be appointed by the shareholders.

The shareholders have appointed KPMG LLP as independent external auditors to express an opinion as to whether the consolidated financial statements present fairly, in all material respects, the Company's consolidated financial position, results of operations and cash flows in accordance with GAAP. The reports of KPMG LLP outline the scope of its examinations and its opinions on the consolidated financial statements and the effectiveness of the Company's internal control over financial reporting.

Report of Independent Registered Public Accounting Firm

**To the Shareholders and Board of Directors TC Energy Corporation:**

**Opinion on the Consolidated Financial Statements**

We have audited the accompanying consolidated balance sheets of TC Energy Corporation (the Company) as of December 31, 2025 and 2024, the related consolidated statements of income, comprehensive income, equity, and cash flows for each of the years in the three-year period ended December 31, 2025, and the related notes (collectively, the consolidated financial statements). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2025 and 2024, and the results of operations and its cash flows for each of the years in the three-year period ended December 31, 2025, in conformity with U.S. generally accepted accounting principles.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the Company's internal control over financial reporting as of December 31, 2025, based on criteria established in Internal Control – Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission, and our report dated February 12, 2026 expressed an unqualified opinion on the effectiveness of the Company's internal control over financial reporting.

**Basis for Opinion**

These consolidated financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on these consolidated financial statements based on our audits. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud. Our audits included performing procedures to assess the risks of material misstatement of the consolidated financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the consolidated financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements. We believe that our audits provide a reasonable basis for our opinion.

**Critical Audit Matters**

The critical audit matters communicated below are matters arising from the current period audit of the consolidated financial statements that were communicated or required to be communicated to the audit committee and that: (1) relate to accounts or disclosures that are material to the consolidated financial statements and (2) involved our especially challenging, subjective, or complex judgments. The communication of critical audit matters does not alter in any way our opinion on the consolidated financial statements, taken as a whole, and we are not, by communicating the critical audit matters below, providing separate opinions on the critical audit matters or on the accounts or disclosures to which they relate.

**Determination of fair value of the Southeast Gateway pipeline** 

As discussed in Notes 2 and 9 to the consolidated financial statements, the Company recognized a sales-type lease for the Southeast Gateway pipeline and recorded net investment in lease of $6.6 billion and selling profit or loss of nil upon derecognition of the carrying value of the underlying assets. At lease commencement, the Company recognizes a net investment in lease equal to the present value of the future lease payments and the estimated residual value of the underlying assets discounted at the rate implicit in the lease. The carrying value of the underlying assets is derecognized, with related gains/losses, if any, recognized in the Consolidated statement of income.

We identified the determination of fair value of the Southeast Gateway pipeline as a critical audit matter. The extent of management judgment with regards to certain qualitative factors that support the conclusion that the fair value of the Southeast Gateway pipeline approximated the carrying value of its underlying assets required subjective auditor judgment. &nbsp;&nbsp;&nbsp;&nbsp;In addition, the audit effort associated with this evaluation required specialized skills and knowledge.

130 \| TC Energy **Consolidated Financial Statements** 2025

------

The following are the primary procedures we performed to address this critical audit matter. We evaluated the design and tested the operating effectiveness of certain internal controls related to this critical audit matter. This included controls related to the Company's determination that the fair value of the Southeast Gateway pipeline approximated the carrying value of its underlying assets. We evaluated the Company's qualitative assessment of factors that supported the Company's judgment that the fair value of the underlying assets approximated their carrying value. We evaluated the Company's forecasted cash flows derived from a market participant's expected use of the underlying assets to determine an implied rate of return, which was compared to estimated rates of return a market participant would require. In addition, we involved valuation professionals with specialized skills and knowledge, who assisted in:

• evaluating the implied return of the underlying assets by independently developing an expectation for the rate of return a market participant would expect by using publicly available market data for comparable entities; and

• evaluating the implied return of the underlying assets by comparing the implied EBITDA multiple to EBITDA multiples using publicly available market data for comparable entities.

**Valuation of goodwill for the Columbia reporting unit**

As discussed in Notes 2 and 13 to the consolidated financial statements, the goodwill balance as of December 31, 2025 for the Columbia reporting unit was $10,082 million. The Company performs an annual review for goodwill impairment at the reporting unit level which is one level below the Company's operating segments. The Company can elect to proceed directly to the quantitative goodwill impairment test for any of its reporting units. If the quantitative goodwill impairment test is performed, the Company compares the fair value of the reporting unit to its carrying value, including goodwill. If the carrying value of a reporting unit exceeds its fair value, goodwill impairment is measured at the amount by which the reporting unit's carrying value exceeds its fair value. The fair value of the reporting unit was determined by using a discounted cash flow model which requires the use of assumptions related to revenue and capital expenditure projections (collectively, the "key assumptions"). The Company elected to proceed directly to the quantitative goodwill impairment test as of December 31, 2025 for the Columbia reporting unit and determined that the fair value of the Columbia reporting unit, exceeded its carrying value, including goodwill, as of December 31, 2025. We identified the evaluation of the key assumptions used in the valuation of goodwill for the Columbia reporting unit as a critical audit matter. A high degree of auditor judgment was required to evaluate the key assumptions. Minor changes to the key assumptions could have had a significant effect on the Company's determination of the fair value of the Columbia reporting unit.

The following are the primary procedures we performed to address this critical audit matter. We evaluated the design and tested the operating effectiveness of certain internal controls related to the Company's determination of the fair value of the Columbia reporting unit and its evaluation of the key assumptions. We compared the Company's key assumptions used in the prior quantitative goodwill impairment test to actual results to assess the Company's ability to accurately forecast. We evaluated the Company's key assumptions in the December 31, 2025 impairment test by comparing them to actual historical results, the outcome of the Columbia Gas Settlement and to assumptions used in industry publications related to North American and global energy consumption and production forecasts.

Report of Independent Registered Public Accounting Firm

**To the Shareholders and Board of Directors TC Energy Corporation:**

**Opinion on Internal Control Over Financial Reporting**

We have audited TC Energy Corporation's (the Company) internal control over financial reporting as of December 31, 2025, based on criteria established in Internal Control – Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission. In our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2025, based on criteria established in Internal Control – Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the consolidated balance sheets of the Company as of December 31, 2025 and 2024, the related consolidated statements of income, comprehensive income, equity, and cash flows for each of the years in the three-year period ended December 31, 2025, and the related notes (collectively, the consolidated financial statements), and our report dated February 12, 2026 expressed an unqualified opinion on those consolidated financial statements.

**Basis for Opinion**

The Company's management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management's Report on Internal Control over Financial Reporting included in the Company's Consolidated Financial Statements. Our responsibility is to express an opinion on the Company's internal control over financial reporting based on our audit. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audit also included performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

**Definition and Limitations of Internal Control Over Financial Reporting**

A company's internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company's internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company's assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Notes to consolidated financial statements

**1. DESCRIPTION OF TC ENERGY'S BUSINESS**

TC Energy Corporation (TC Energy or the Company) is a leading North American energy infrastructure company which operates in four business segments: Canadian Natural Gas Pipelines, U.S. Natural Gas Pipelines, Mexico Natural Gas Pipelines and Power and Energy Solutions. These segments offer different products and services, including certain natural gas and electricity marketing and storage services. The Company also has a Corporate segment, consisting of corporate and administrative functions that provide governance, financing and other support to the Company's business segments.

**Canadian Natural Gas Pipelines**

The Canadian Natural Gas Pipelines segment primarily consists of the Company's investments in 40,984 km (25,467 miles) of regulated natural gas pipelines currently in operation.

**U.S. Natural Gas Pipelines**

The U.S. Natural Gas Pipelines segment primarily consists of the Company's investments in 49,587 km (30,811 miles) of regulated natural gas pipelines, 532 Bcf of regulated natural gas storage facilities and other assets currently in operation.

**Mexico Natural Gas Pipelines**

The Mexico Natural Gas Pipelines segment primarily consists of the Company's investments in 3,600 km (2,235 miles) of regulated natural gas pipelines currently in operation.

**Power and Energy Solutions**

The Power and Energy Solutions segment primarily consists of the Company's investments in approximately 4,650 MW of power generation facilities and 118 Bcf of non-regulated natural gas storage facilities. These assets are located in Alberta, Ontario, Québec, New Brunswick and Texas. In addition, TC Energy has physical and virtual power purchase agreements (PPAs) in Canada and the U.S. to buy and/or sell power from wind and solar facilities. These PPAs have the potential to be leases, derivatives or revenue arrangements depending on the contractual terms of the agreement.

**Spinoff of Liquids Pipelines Business**

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). Refer to Note 4, Discontinued operations, for additional information.

**2. ACCOUNTING POLICIES**

The Company's consolidated financial statements have been prepared by management in accordance with U.S. generally accepted accounting principles. Amounts are stated in Canadian dollars unless otherwise indicated.

**Basis of Presentation**

These consolidated financial statements include the accounts of TC Energy and its subsidiaries. The Company consolidates variable interest entities (VIEs) for which it is considered to be the primary beneficiary as well as voting interest entities in which it has a controlling financial interest. Interests in consolidated entities owned by other parties are presented as non-controlling interests. TC Energy uses the equity method of accounting for joint ventures in which the Company is able to exercise joint control and for investments in which the Company is able to exercise significant influence.

The Spinoff Transaction represented a strategic shift that had a major effect on the Company's operations and consolidated financial results. Accordingly, the historical 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. The Notes to the consolidated financial statements reflect continuing operations only, unless otherwise indicated. Prior to the spinoff, the operations of the Liquids Pipelines business were materially reported as the Company's Liquids Pipelines segment. Refer to Note 4, Discontinued operations, and Note 5, Segmented information, for additional information.

Certain prior year amounts have been reclassified to conform to current year presentation.

**Out-of-Period Adjustments**

During second quarter 2025, the Company recorded out-of-period adjustments to reclassify a pro rata portion of its net investment hedge losses recorded in Accumulated other comprehensive income (loss)(AOCI).

The adjustments included (i) a reclassification of net investment hedge losses of $348 million from AOCI to Non-controlling interests (NCI) related to the sale of 40 per cent of Columbia Gas and Columbia Gulf on October 4, 2023, which was presented as Impact of non-controlling interest and Disposition of equity interests, respectively, in the Consolidated statement of equity; and (ii) a reclassification of net investment hedge losses of $542 million related to the spinoff of the Company's Liquids Pipelines business that occurred on October 1, 2024 from AOCI to Retained earnings (Accumulated deficit).

The Company determined that the impact of these out-of-period adjustments was not material, individually or in the aggregate, to any previously reported quarterly or annual financial statements and is not material to the Company's consolidated financial statements.

**Use of Estimates and Judgments**

In preparing these 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.

Certain estimates and judgments have a material impact on the consolidated financial statements where the assumptions underlying these accounting estimates relate to matters that are highly uncertain at the time they are made or are subjective. These estimates and judgments include, but are not limited to:

• fair value of the Southeast Gateway pipeline used to record a net investment upon lease commencement (Note 9)

• fair value of reporting units that contain goodwill (Note 13).

Some of the estimates and judgments the Company has to make have a material impact on the consolidated financial statements, but do not involve significant subjectivity or uncertainty. These estimates and judgments include, but are not limited to:

• recoverability and depreciation rates of plant, property and equipment (Note 8)

• allocation of consideration to lease and non-lease components in a contract that contains a lease (Note 9)

• assumptions used to measure the carrying amount of and expected credit losses on net investment in leases and certain contract assets (Notes 9 and 27)

• fair value of equity investments (Note 10)

• carrying value of regulatory assets and liabilities (Note 12)

• recognition of asset retirement obligations (Note 17)

• provisions for income taxes, including valuation allowances and releases as well as tax positions that may be reviewed as part of an audit by tax authorities (Note 18)

• assumptions used to measure retirement and other post-retirement benefit obligations (Note 26)

• fair value of financial instruments (Notes 26 and 27)

• commitments and provisions for contingencies and guarantees (Note 30).

TC Energy continues to assess climate-related impacts on the consolidated financial statements. There are ongoing developments in the sustainability frameworks and regulatory initiatives that could further impact accounting estimates and judgments including, but not limited to, assessment of asset useful lives, goodwill valuation, impairment of plant, property and equipment, accrued environmental costs and asset retirement obligations. The impact of these changes is continuously assessed to ensure any changes in assumptions that would impact estimates listed above are adjusted on a timely basis.

Actual results could differ from these estimates.

**Regulation**

Certain Canadian, U.S. and Mexico natural gas pipeline and storage assets are regulated with respect to construction, operations and the determination of tolls. In Canada, regulated natural gas pipelines are subject to the authority of the Canada Energy Regulator (CER), the Alberta Energy Regulator or the BC Energy Regulator. In the U.S., regulated interstate natural gas pipelines and regulated natural gas storage assets are subject to the authority of the Federal Energy Regulatory Commission (FERC). In Mexico, regulated natural gas pipelines are subject to the authority of the National Energy Commission (CNE). Rate-regulated accounting (RRA) standards may impact the timing of the recognition of certain revenues and expenses in TC Energy's rate-regulated businesses which may differ from that otherwise recognized in non-rate-regulated businesses to reflect the economic impact of the regulators' decisions regarding revenues and tolls. Regulatory assets represent costs that are expected to be recovered in customer rates in future periods and regulatory liabilities represent amounts that are expected to be returned to customers through future rate-setting processes. An operation qualifies for the use of RRA when it meets three criteria:

• a regulator must establish or approve the rates for the regulated services or activities

• the regulated rates must be designed to recover the cost of providing the services or products

• it is reasonable to assume that rates set at levels to recover the cost can be charged to and collected from customers because of the demand for services or products and the level of direct or indirect competition.

TC Energy's businesses that apply RRA currently include natural gas pipelines in Canada, U.S. and Mexico and regulated U.S. natural gas storage.

**Revenue Recognition**

The total consideration for services and products to which the Company expects to be entitled can include fixed and variable amounts. The Company has variable revenue that is subject to factors outside the Company's influence, such as market prices, actions of third parties and weather conditions. The Company considers some of this variable revenue to be constrained as it cannot be reliably estimated and, therefore, variable revenue is recognized only to the extent it is probable a significant reversal in cumulative revenue will not occur.

The Company's contracts with customers include natural gas pipelines capacity arrangements and transportation contracts, power generation contracts, natural gas storage and other contracts. Revenues from contracts with customers are recognized net of any commodity taxes collected from customers which are subsequently remitted to governmental authorities.

Revenues from non-lease components associated with a lease arrangement are recognized systematically over the term of the contract.

The majority of income earned from marketing activities, as it relates to the purchase and sale of natural gas and electricity, is recorded on a net basis in the month of delivery.

**Canadian Natural Gas Pipelines**

***Capacity Arrangements and Transportation***

Revenues from the Company's Canadian natural gas pipelines are generated from contractual arrangements for committed capacity and from the transportation of natural gas. Revenues earned from firm contracted capacity arrangements are recognized ratably over the term of the contract regardless of the amount of natural gas that is transported. Transportation revenues for interruptible or volumetric-based services are recognized when the service is performed.

Revenues from the Company's Canadian natural gas pipelines under federal jurisdiction are subject to regulatory decisions by the CER. The tolls charged on these pipelines are based on revenue requirements designed to recover the costs of providing natural gas capacity for transportation services, which includes a return of and on capital, as approved by the CER. The Company's Canadian natural gas pipelines are generally not subject to earnings volatility related to variances in revenues and costs. These variances, except as related to incentive arrangements, are generally subject to deferral treatment and are recovered or refunded in future tolls. Revenues recognized prior to a CER decision on rates for that period reflect the CER's last approved return on equity (ROE) assumptions. Adjustments to revenues are recorded when the CER decision is received. Canadian natural gas pipelines' revenues are invoiced and received on a monthly basis. The Company does not take ownership of the natural gas that it transports for customers.

------

**U.S. Natural Gas Pipelines**

***Capacity Arrangements and Transportation***

Revenues from the Company's U.S. natural gas pipelines are generated from contractual arrangements for committed capacity and from the transportation of natural gas. Revenues earned from firm contracted capacity arrangements are generally recognized ratably over the term of the contract regardless of the amount of natural gas that is transported. Transportation revenues for interruptible or volumetric-based services are recognized when the service is performed.

The Company's U.S. interstate natural gas pipelines are subject to FERC regulations and, as a result, a portion of revenues collected may be subject to refund if invoiced during an interim period when a rate proceeding is ongoing. Allowances for these potential refunds are recognized using management's best estimate based on the facts and circumstances of the proceeding. Any allowances that are recognized during the proceeding process are refunded or retained at the time a regulatory decision becomes final. U.S. natural gas pipelines' revenues are invoiced and received on a monthly basis. The Company does not take ownership of the natural gas that it transports for customers.

***Natural Gas Storage and Other***

Revenues from the Company's regulated U.S. natural gas storage services are generated mainly from firm committed capacity storage contracts. The performance obligation in these contracts is the reservation of a specified amount of capacity for storage including specifications with regard to the amount of natural gas that can be injected or withdrawn on a daily basis. Revenues are recognized ratably over the contract period for firm committed capacity regardless of the amount of natural gas that is stored, and when gas is injected or withdrawn for interruptible or volumetric-based services. Natural gas storage services revenues are invoiced and received on a monthly basis. The Company does not take ownership of the natural gas that it stores for customers.

The Company owns mineral rights associated with certain natural gas storage facilities. These mineral rights can be leased or contributed to producers of natural gas in return for a royalty interest which is recognized when natural gas and associated liquids are produced.

**Mexico Natural Gas Pipelines**

***Capacity Arrangements and Transportation***

Revenues from certain of the Company's Mexico natural gas pipelines are primarily collected based on negotiated firm capacity contracts and are generally recognized ratably over the term of the contract. Transportation revenues related to interruptible or volumetric-based services are recognized when the service is performed. Mexico natural gas pipelines' revenues are invoiced and received on a monthly basis. The Company does not take ownership of the natural gas that it transports for customers.

***Other***

The Company generates revenues from operating and maintenance services provided on leased pipelines. Revenues earned from these services are recognized ratably over the term of the contract.

**Power and Energy Solutions**

***Power***

Revenues from the Company's Power and Energy Solutions business are primarily derived from long-term contractual commitments to provide power capacity to meet the demands of the market and from the sale of electricity to both centralized markets and to customers. Power generation revenues also include revenues from the sale of steam to customers. Revenues and capacity payments are recognized as the services are provided and as electricity and steam is delivered. Power generation revenues are invoiced and received on a monthly basis.

***Natural Gas Storage and Other***

Non-regulated natural gas storage contracts include park, loan and term storage arrangements. Revenues are recognized as the services are provided. Term storage revenues are invoiced and received on a monthly basis. Revenues from ancillary services are recognized as the service is provided.

**Cash and Cash Equivalents**

The Company's Cash and cash equivalents consist of cash and highly liquid short-term investments with original maturities of three months or less and are recorded at cost, which approximates fair value.

TC Energy **Consolidated Financial Statements** 2025 \| 141

------

**Inventories**

Inventories primarily consist of materials and supplies including spare parts and fuel, proprietary natural gas inventory in storage and emissions allowances and credits not held for compliance. The Company purchases certain emissions allowances and credits as part of bundled arrangements that also include the purchase of electricity for a fixed price. The cost allocated to emissions allowances and credits under such arrangements is based on observable market prices. Inventories are carried at the lower of cost and net realizable value.

**Assets Held for Sale**

The Company classifies assets as held for sale when management approves and commits to a formal plan to actively market a disposal group and expects the sale to close within the next 12 months. Upon classifying an asset as held for sale, the asset is recorded at the lower of its carrying amount or its estimated fair value, net of selling costs and any losses are recognized in net income. Gains related to the expected sale of these assets are not recognized until the transaction closes. Once an asset is classified as held for sale, depreciation expense is no longer recorded.

**Plant, Property and Equipment**

**Natural Gas Pipelines**

Plant, property and equipment for natural gas pipelines is carried at cost. Depreciation is calculated on a straight-line basis once the assets are ready for their intended use. Pipeline and compression equipment are depreciated at annual rates ranging from 0.625 per cent to 6.67 per cent and metering and other plant equipment are depreciated at various rates reflecting their estimated useful lives. The cost of major overhauls of equipment is capitalized and depreciated over the estimated service lives of the overhauls. The cost of regulated natural gas pipelines includes an allowance for funds used during construction (AFUDC) consisting of a debt component and an equity component based on the rate of return on rate base approved by regulators. AFUDC is reflected as an increase in the cost of the assets in Plant, property and equipment with a corresponding increase in Allowance for funds used during construction in the Consolidated statement of income. The equity component of AFUDC is a non-cash expenditure. Interest is capitalized during construction of non-regulated natural gas pipelines.

Natural gas pipelines' linepack and natural gas storage base gas are valued at cost and are maintained to ensure adequate pressure exists to transport natural gas through pipelines and deliver natural gas held in storage. Linepack and base gas are not depreciated.

When rate-regulated natural gas pipelines retire plant, property and equipment from service, the original book cost is removed from the gross plant amount and recorded as a reduction to accumulated depreciation with no amount recorded to net income. Costs incurred to remove plant, property and equipment from service, net of any salvage proceeds, are also recorded in accumulated depreciation.

***Other***

The Company participates as a working interest partner in the development of certain Marcellus and Utica acreage. The working interest allows the Company to invest in drilling activities in addition to receiving a royalty interest in well production. The Company uses the successful efforts method of accounting for natural gas and crude oil resulting from its portion of drilling activities. Capitalized well costs are depleted based on the units of production method.

**Power and Energy Solutions**

Plant, property and equipment for Power and Energy Solutions assets are recorded at cost and, once the assets are ready for their intended use, depreciated by major component on a straight-line basis over their estimated service lives at average annual rates ranging from two per cent to 20 per cent. Other equipment is depreciated at various rates reflecting their estimated useful lives. The cost of major overhauls of equipment is capitalized and depreciated over the estimated service lives of the overhauls. Interest is capitalized on facilities under construction. When these assets are retired from plant, property and equipment, the original book cost and related accumulated depreciation are derecognized and any gain or loss is recorded in net income.

Natural gas storage base gas, which is valued at original cost, represents gas volumes that are maintained to ensure adequate reservoir pressure exists to deliver gas held in storage. Base gas is not depreciated.

**Corporate**

Corporate plant, property and equipment is recorded at cost and depreciated on a straight-line basis over its estimated useful life at average annual rates ranging from four per cent to 20 per cent.

142 \| TC Energy **Consolidated Financial Statements** 2025

------

**Capital Projects in Development**

The Company capitalizes project costs once advancement of the project to construction stage is probable or costs are otherwise likely to be recoverable. The Company capitalizes interest costs for non-regulated projects in development and AFUDC for regulated projects in development. Capital projects in development are included in Other long-term assets on the Consolidated balance sheet. These represent larger projects that generally require regulatory or other approvals before physical construction can begin. Once approvals are received, projects are moved to plant, property and equipment under construction.

**Leases**

The Company determines if&nbsp;&nbsp;&nbsp;&nbsp; a contract contains a lease at inception, or upon modification, of a contract by using judgment in assessing the following aspects: 1) the contract specifies an identified asset which is physically distinct or, if not physically distinct, represents substantially all of the capacity of the asset; 2) the contract provides the customer with the right to obtain substantially all of the economic benefits from the use of the asset; and 3) the customer has the right to direct how and for what purpose the identified asset is used throughout the period of the contract.

If the contract is determined to contain a lease, further judgment is required to identify separate lease components of the arrangement by assessing whether the lessee can benefit from the right of use either on its own or together with other resources that are readily available to the lessee, as well as if the right of use is neither highly dependent on, nor highly interrelated, with the other rights to use underlying assets in the contract.

The Company considers non-lease components as distinct elements of a contract that are not related to the use of the leased asset. A good or service that is provided to a customer is distinct if: 1) the&nbsp;&nbsp;&nbsp;&nbsp;customer can benefit from the good or service either on its own or together with other resources that are readily available to the customer; and 2) the entity's promise to transfer the good or service to the customer is separately identifiable from other promises in the contract. The Company applies the practical expedient to not separate lease and non-lease components for all lessee contracts and facilities for which the Company is the lessor in an operating lease.

**Lessee Accounting Policy**

Operating leases are recognized as right-of-use (ROU) assets and included in Plant, property and equipment while corresponding liabilities are included in Accounts payable and other and Other long-term liabilities on the Consolidated balance sheet.

Operating lease ROU assets and operating lease liabilities are recognized based on the present value of the future minimum lease payments over the lease term at the commencement date of the lease agreement. Lease terms may include options to extend or terminate the lease when it is reasonably certain that the Company will exercise that option. As the Company's lease contracts do not provide an implicit interest rate, the Company uses its incremental borrowing rate based on the information available at commencement date, or upon modification of a lease, in determining the present value of future payments. Operating lease expense is recognized on a straight-line basis over the lease term and included in Plant operating costs and other in the Consolidated statement of income.

The Company applies the practical expedient to not recognize ROU assets or lease liabilities for leases that qualify for the short-term lease recognition exemption.

**Lessor Accounting Policy**

The Company provides transportation and other services on certain assets to customers according to long-term service agreements through sales-type and operating leases.

In a sales-type lease, the Company measures the total consideration within the contract at lease commencement, or upon modification of a lease. When a lease arrangement contains more than one lease and/or non-lease component, a portion of the contract consideration is allocated to each component based on the stand-alone selling price for each distinct service. The Company applies judgment to determine reasonable estimates of the expected future cost of satisfying the performance obligations of each service. The payments associated with lease components are apportioned between a reduction in the net investment in lease and sales-type lease income.

At lease commencement, the Company recognizes a net investment in lease equal to the present value of both the future lease payments and the estimated residual value of the leased asset discounted at the rate implicit in the lease. The plant, property and equipment of the leased asset is derecognized, with related gains/losses, if any, recognized in the Consolidated statement of income. Sales-type lease income is determined using the rate implicit in the lease and is recorded in Revenues.

TC Energy **Consolidated Financial Statements** 2025 \| 143

------

The Company is the lessor within certain other contracts, including PPAs, that are accounted for as operating leases. In an operating lease, the leased asset remains capitalized in Plant, property and equipment on the Consolidated balance sheet and is depreciated over its useful life, while lease payments are recognized as revenue over the term of the lease on a straight-line basis. Variable lease payments are recognized as income in the period in which they occur.

**Impairment of Long-Lived Assets**

The Company reviews long-lived assets such as plant, property and equipment and capital projects in development for impairment whenever events or changes in circumstances indicate the carrying value may not be recoverable. If the total of the estimated undiscounted future cash flows for an asset within plant, property and equipment, or the estimated selling price of any long-lived asset is less than the carrying value of an asset, an impairment loss is recognized for the excess of the carrying value over the estimated fair value of the asset.

**Impairment of Equity Method Investments**

The Company reviews equity method investments for impairment when an event or change in circumstances has a significant adverse effect on the investment's fair value. Where the Company concludes an investment's fair value is below its carrying value, the Company then determines whether the impairment is other-than-temporary, and if so, an impairment loss is recognized for the excess of the carrying value over the estimated fair value of the investment, not exceeding the carrying value of the investment.

**Acquisitions and Goodwill**

The Company accounts for business combinations using the acquisition method of accounting and, accordingly, the assets and liabilities of the acquired entities are primarily measured at their estimated fair values at the date of acquisition. The excess of the fair value of the consideration transferred over the estimated fair value of the net assets acquired is classified as goodwill. Goodwill is not amortized and is tested for impairment on an annual basis, or more frequently if events or changes in circumstances indicate that it might be impaired.

The annual review for goodwill impairment is performed at the reporting unit level which is one level below the Company's operating segments. The Company can initially assess qualitative factors to determine whether events or changes in circumstances indicate that goodwill might be impaired. The factors the Company considers include, but are not limited to, macroeconomic conditions, industry and market considerations, current valuation multiples and discount rates, cost factors, historical and forecasted financial results and events specific to that reporting unit.

If the Company concludes that it is not more likely than not that the fair value of the reporting unit is greater than its carrying value, the Company will then perform a quantitative goodwill impairment test. The Company can elect to proceed directly to the quantitative goodwill impairment test for any of its reporting units. If the quantitative goodwill impairment test is performed, the Company compares the fair value of the reporting unit to its carrying value, including its goodwill. If the carrying value of a reporting unit exceeds its fair value, goodwill impairment is measured at the amount by which the reporting unit's carrying value exceeds its fair value. The fair value of a reporting unit is determined by using a discounted cash flow model which requires the use of assumptions that may include, but are not limited to, revenue and capital expenditure projections, valuation multiples and discount rates. The Company has elected to allocate goodwill impairment charges first to goodwill that is non-deductible for income tax purposes, with any remaining charge allocated to tax-deductible goodwill.

When a portion of a reporting unit that constitutes a business is disposed, goodwill associated with that business is included in the carrying amount of the business in determining the gain or loss on disposal. The amount of goodwill disposed is determined based on the relative fair values of the business to be disposed and the portion of the reporting unit that will be retained. A goodwill impairment test will be completed for the goodwill that will be retained.

**Non-Controlling Interests**

Non-controlling interests (NCI) represent third-party ownership interests in certain consolidated subsidiaries of the Company. Partial dispositions which result in a change in the Company's ownership interest, but do not result in a change in control, of a subsidiary that constitutes a business are accounted for as equity transactions. No gain or loss is recognized in earnings. At the time of partial disposition, NCI is recorded as the third party's ownership interest in the Company's carrying value of the net assets of the subsidiary. Any difference between the amount by which the NCI is adjusted and the fair value of the consideration paid or received is recognized in Additional paid-in capital and/or Retained earnings (Accumulated deficit).

**Loans and Receivables**

Loans receivable from affiliates and accounts receivable are measured at amortized cost.

**Impairment of Financial Assets**

The Company reviews financial assets, inclusive of net investment in leases and certain contract 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. An expected credit loss (ECL) is calculated using a model and methodology based on assumptions and judgment considering historical data, current counterparty information as well as reasonable and supportable forecasts of future economic conditions.

The ECL is recognized in Plant operating costs and other in the Consolidated statement of income, and is presented on the Consolidated balance sheet as a reduction to the carrying value of the related financial asset.

**Restricted Investments**

The Company has certain investments that are restricted as to their withdrawal and use. These restricted investments are recorded at fair value on the Consolidated balance sheet.

As a result of the CER's Land Matters Consultation Initiative (LMCI), TC Energy is required to collect funds to cover estimated future pipeline abandonment costs for larger CER-regulated Canadian pipelines. Funds collected are placed in trusts that hold and invest the funds and are accounted for as restricted investments (LMCI restricted investments). LMCI restricted investments may only be used to fund the abandonment of the CER-regulated pipeline facilities, therefore, a corresponding regulatory liability is recorded on the Consolidated balance sheet.

The Company also has other restricted investments that have been set aside to fund insurance claim losses to be paid by the Company's wholly-owned captive insurance subsidiary.

**Income Taxes**

The Company uses the asset and liability method of accounting for income taxes. This method requires the recognition of deferred income tax assets and liabilities for future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred income tax assets and liabilities are measured using enacted tax rates at the balance sheet date that are anticipated to apply to taxable income in the years in which temporary differences are expected to be reversed or settled. Changes to these balances are recognized in net income in the period in which they occur, except for changes in balances related to regulated natural gas pipelines which are deferred until they are refunded or recovered in tolls, as permitted by the regulator. Deferred income tax assets and liabilities are classified as non-current on the Consolidated balance sheet. The Company's exposure to uncertain tax positions is evaluated and a provision is made where it is more likely than not that this exposure will materialize.

Canadian income taxes are not provided for on the unremitted earnings of foreign investments that the Company does not intend to repatriate in the foreseeable future.

Any interest and/or penalty incurred related to income tax is reflected in Income tax expense.

**Asset Retirement Obligations**

The Company recognizes the fair value of a liability for asset retirement obligations (ARO) in the period in which it is incurred, when a legal obligation exists and a reasonable estimate of fair value can be made. The fair value is added to the carrying amount of the associated asset and the liability is accreted through charges to Plant operating costs and other in the Consolidated statement of income.

In determining the fair value of ARO, the following assumptions are used:

• the expected retirement date

• the scope and cost of abandonment and reclamation activities that are required

• appropriate inflation and discount rates.

The Company's AROs are substantially related to its power generation facilities. The scope and timing of asset retirements related to the Company's natural gas pipelines and storage facilities are indeterminable because the Company intends to operate them as long as there is supply and demand. As a result, the Company has not recorded an amount for ARO related to these assets.

**Environmental Liabilities and Emission Allowances and Credits**

The Company records liabilities on an undiscounted basis for environmental remediation efforts that are likely to occur and where the cost can be reasonably estimated. These estimates, including associated legal costs, are based on available information using existing technology and enacted laws and regulations and are subject to revision in future periods based on actual costs incurred or new circumstances. TC Energy evaluates recoveries from insurers and other third parties separately from the liability and, when recovery is probable, an asset is recorded separately from the associated liability. These recoveries are presented, along with environmental remediation costs, on a net basis in Plant operating costs and other in the Consolidated statement of income. Variations in one or more of the categories described above could result in additional costs such as fines, penalties and/or expenditures associated with litigation and settlement of claims with respect to environmental liabilities.

Emission allowances or credits purchased for compliance are recorded on the Consolidated balance sheet at historical cost and derecognized when they are utilized or cancelled/retired by government agencies. Compliance costs are expensed when incurred. Allowances granted to or internally generated by TC Energy are not attributed a value for accounting purposes. When required, TC Energy accrues emission liabilities on the Consolidated balance sheet using the best estimate of the amount required to settle the compliance obligation. Allowances and credits not used for compliance are sold and any gain or loss is recorded in Revenues within the Power and Energy Solutions segment in the Consolidated statement of income. The Company records allowances and credits held for compliance in Other current assets and Other long-term assets on the Consolidated balance sheet. Allowances and credits not held for compliance are classified as Inventories on the Consolidated balance sheet.

**Stock Options and Other Compensation Programs**

The Company no longer issues stock options to employees or officers. Stock options granted before 2024 were recorded using the fair value method. Under this method, compensation expense is measured at the grant date based on the fair value as calculated using a binomial model and is recognized on a straight-line basis over the vesting period with an offset to Additional paid-in capital. Forfeitures are accounted for when they occur. Upon exercise of stock options, amounts originally recorded against Additional paid-in capital are reclassified to Common shares on the Consolidated balance sheet.

The Company has medium-term incentive plans under which payments are made to eligible employees. The expense related to these incentive plans is accounted for on an accrual basis. Under these plans, benefits vest when certain conditions are met, including the employees' continued employment during a specified period and achievement of specified corporate

performance targets.

**Employee Post-Retirement Benefits**

The Company sponsors defined benefit pension plans (DB Plans), defined contribution plans (DC Plans), savings plans and other post-retirement benefit plans (OPEB Plans). Contributions made by the Company to the DC Plans and savings plans are expensed in the period in which contributions are made. The cost of the DB Plans and OPEB Plans received by employees is actuarially determined using the projected benefit method pro-rated based on service and management's best estimate of expected plan investment performance, salary escalation, retirement age of employees and expected health care costs.

The DB Plans' assets are measured at fair value at December 31 of each year. The expected return on the DB Plans' assets is determined using market-related values based on a five-year moving average value for all of the DB Plans' assets. Past service costs are amortized over the expected average remaining service life (EARSL) of the employees. Adjustments arising from plan amendments are amortized on a straight-line basis over the EARSL of employees active at the date of amendment. The Company recognizes the overfunded or underfunded status of its DB Plans as an asset or liability, respectively, on its Consolidated balance sheet and recognizes changes in that funded status through Other comprehensive income (loss)(OCI) in the year in which the change occurs. The excess of net actuarial gains or losses over 10 per cent of the greater of the benefit obligation and the market-related value of the DB Plans' assets, if any, is amortized out of AOCI and into net income over the EARSL of the active employees. When the restructuring of a benefit plan gives rise to both a curtailment and a settlement, the curtailment is accounted for prior to the settlement.

For certain regulated operations, post-retirement benefit amounts are recoverable through tolls as benefits are funded. The Company records any unrecognized gains or losses or changes in actuarial assumptions related to these post-retirement benefit plans as either regulatory assets or liabilities. The regulatory assets or liabilities are amortized on a straight-line basis over the EARSL of active employees.

**Foreign Currency Transactions and Translation**

Foreign currency transactions are those transactions whose terms are denominated in a currency other than the currency of the primary economic environment in which the Company or reporting subsidiary operates. This is referred to as the functional currency. Transactions denominated in foreign currencies are translated into the functional currency using the exchange rate prevailing at the date of the transaction. Monetary assets and liabilities denominated in foreign currencies are translated to the functional currency using the rate of exchange in effect at the balance sheet date whereas non-monetary assets and liabilities are translated at the historical rate of exchange in effect on the date of the transaction. Exchange gains and losses resulting from translation of monetary assets and liabilities are recorded in net income except for exchange gains and losses on any foreign currency debt related to Canadian regulated natural gas pipelines, which are deferred until they are refunded or recovered in tolls, as permitted by the CER.

Gains and losses arising from translation of foreign operations' functional currencies to the Company's Canadian dollar reporting currency are reflected in OCI until the operations are sold, at which time the gains and losses are reclassified to net income. For partial dispositions of foreign operations that do not result in a change of control, or dispositions of foreign operations other than by sale, gains and losses are reclassified within equity. Asset and liability accounts are translated at the rate of exchange in effect at the balance sheet date while revenues, expenses, gains and losses are translated at the exchange rate prevailing at the date of the transaction. The Company's U.S. dollar-denominated debt and certain derivative hedging instruments have been designated as a hedge of the net investment in foreign subsidiaries and, as a result, the unrealized foreign exchange gains and losses on the U.S. dollar-denominated debt and derivatives are also reflected in OCI.

**Derivative Instruments and Hedging Activities**

All derivative instruments are recorded on the Consolidated balance sheet at fair value, unless they qualify for and are designated under a normal purchase and normal sales exemption, or are considered to meet other permitted exemptions.

The Company applies hedge accounting to arrangements that qualify for and are designated for hedge accounting treatment. This includes fair value and cash flow hedges as well as hedges of foreign currency exposures of net investments in foreign operations. Hedge accounting is discontinued prospectively if the hedging relationship ceases to be effective or the hedging or hedged items cease to exist as a result of maturity, expiry, sale, termination, cancellation or exercise.

In a fair value hedging relationship, the carrying value of the hedged item is adjusted for changes in fair value attributable to the hedged risk and these changes are recognized in net income. Changes in the fair value of the hedged item, to the extent that the hedging relationship is effective, are offset by changes in the fair value of the hedging item, which are also recorded in net income. Changes in the fair value of foreign exchange and interest rate fair value hedges are recorded in Interest income and other and Interest expense, respectively. If hedge accounting is discontinued, the carrying value of the hedged item is no longer adjusted and the cumulative fair value adjustments to the carrying value of the hedged item are amortized to net income over the remaining term of the original hedging relationship.

In a cash flow hedging relationship, the change in the fair value of the hedging derivative is recognized in OCI. When hedge accounting is discontinued, the amounts recognized previously in AOCI are reclassified to Revenues, Interest expense and Interest income and other, as appropriate, during the periods when the variability in cash flows of the hedged item affects net income or as the original hedged item settles. Gains and losses on derivatives are reclassified immediately to net income from AOCI when the hedged item is sold or terminated early, or when it becomes probable that the anticipated transaction will not occur. Termination payments on interest rate derivatives are classified as a financing activity in the Consolidated statement of cash flows.

In hedging the foreign currency exposure of a net investment in a foreign operation, the foreign exchange gains and losses on the hedging instruments are recognized in OCI. The amounts recognized previously in AOCI are reclassified consistent with gains and losses arising from the translation of foreign operations, when the foreign operation is either entirely or partially disposed of.

In some cases, derivatives do not meet the specific criteria for hedge accounting treatment. In these instances, the changes in fair value are recorded in net income in the period of change.

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 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 rate payers in subsequent periods when the derivative settles.

TC Energy **Consolidated Financial Statements** 2025 \| 147

------

Derivatives embedded in other financial instruments or contracts (host instrument) are recorded as separate derivatives. Embedded derivatives are measured at fair value if their economic characteristics are not clearly and closely related to those of the host instrument, their terms are the same as those of a stand-alone derivative and the total contract is not held for trading or accounted for at fair value. When changes in the fair value of embedded derivatives are measured separately, they are included in net income.

**Long-Term Debt Transaction Costs and Issuance Costs**

The Company records long-term debt transaction costs and issuance costs as a deduction from the carrying amount of the related debt liability and amortizes these costs using the effective interest method except those related to the Canadian natural gas regulated pipelines, which continue to be amortized on a straight-line basis in accordance with the provisions of regulatory tolling mechanisms.

**Guarantees**

Upon issuance, the Company records the fair value of certain guarantees entered into by the Company on behalf of a partially-owned entity or by partially-owned entities for which contingent payments may be made. The fair value of these guarantees is estimated by discounting the cash flows that would be incurred by the Company if letters of credit were used in place of the guarantees as appropriate in the circumstances. Guarantees are recorded as an increase to Equity investments or Plant, property and equipment and a corresponding liability is recorded in Other long-term liabilities. The release from the obligation is recognized either over the term of the guarantee or upon expiration or settlement of the guarantee.

**Variable Interest Entities**

A VIE is a legal entity that does not have sufficient equity at risk to finance its activities without additional subordinated financial support or is structured such that equity investors lack the ability to make significant decisions relating to the entity's operations through voting rights or do not substantively participate in the gains and losses of the entity. The assessment of whether an entity is a VIE and, if so, whether the Company is the primary beneficiary, is completed at the inception of the entity or at a reconsideration event.

**Consolidated VIEs**

The Company's consolidated VIEs consist of legal entities where the Company has a variable interest and for which it is considered the primary beneficiary. As the primary beneficiary, the Company has the power, through voting or similar rights, to direct the activities of the VIE that most significantly impact economic performance including: purchasing or selling significant assets; maintenance and operations of assets; incurring additional indebtedness; or determining the strategic operating direction of the entity. In addition, the Company has the obligation to absorb losses or the right to receive benefits from the consolidated VIE that could potentially be significant to the VIE.

**Non-Consolidated VIEs**

The Company's non-consolidated VIEs consist of legal entities where the Company has a variable interest but is not the primary beneficiary as it does not have the power (either explicit or implicit), through voting or similar rights, to direct the activities that most significantly impact the economic performance of these VIEs or where this power is shared with third parties. The Company contributes capital to these VIEs and receives ownership interests that provide it with residual claims on assets after liabilities are paid. Non-consolidated VIEs are accounted for as equity investments.

The Company's maximum exposure to loss is the maximum loss that could potentially be recorded through net income in future periods as a result of the Company's variable interest in a VIE.

**3. ACCOUNTING CHANGES**

**Changes in Accounting Policies for 2025**

**Income Taxes**

In December 2023, the FASB issued new guidance to enhance the transparency and usefulness of income tax disclosures through improvements to the rate reconciliation and income taxes paid information. The new guidance requires entities to disclose specific categories in the rate reconciliation and sets specific disaggregation requirements for reconciling items that meet certain thresholds. Additionally, entities are required to disclose disaggregated information on income taxes paid, income from continuing operations before tax and income tax expense from continuing operations. This new guidance was effective for annual periods beginning January 1, 2025. The Company adopted the guidance on a retrospective basis. The adoption of this guidance did not have a material impact on the Company's financial position or results of operations. Refer to Note 18, Income taxes, for additional information and the effects of the new guidance.

**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 &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;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.

**4. DISCONTINUED OPERATIONS**

**Spinoff of Liquids Pipelines Business**

On October 1, 2024, TC Energy completed the spinoff of its Liquids Pipelines business. Pursuant to the Spinoff Transaction, TC Energy and South Bow executed a series of agreements to outline the parameters and guidelines that govern their ongoing relationship, including a Transition Services Agreement, Tax Matters Agreement and a Separation Agreement.

The Transition Services Agreement was established to specify certain services that TC Energy will provide to South Bow for a period of up to two years.

The Tax Matters Agreement governs TC Energy and South Bow's tax rights and obligations after the Spinoff Transaction. The agreement imposes certain restrictions on both TC Energy and South Bow in order to preserve the tax-free status of the spinoff. In the event the Spinoff Transaction is not tax-free, the agreement allocates tax liabilities by generally assigning responsibility to either TC Energy or South Bow to the extent that the failure to qualify is attributable to actions, events or transactions, or a breach of the representations or covenants made by that entity.

The Separation Agreement set forth the terms of the separation of the Liquids Pipelines business from the business of TC Energy, including the transfer of certain assets related to the Liquids Pipelines business from TC Energy to South Bow and the allocation of certain liabilities and obligations related to the Liquids Pipelines business between TC Energy and South Bow.

During 2025, TC Energy reached an agreement with South Bow with respect to liabilities the Company indemnified South Bow for under the Separation Agreement, releasing the Company from those liabilities. Inclusive of the recognition of the settlement, a net loss from discontinued operations of $183 million, net of tax was recognized. Payments related to the settlement commenced in fourth quarter 2025 and will be completed in 2026.

In addition, the Company revised its estimate of future recoveries, resulting in a $29 million impairment, which was included in Net income (loss) from discontinued operations, net of tax in the Consolidated statement of income.

**Separation Costs**

Liquids Pipelines business separation costs primarily include internal costs related to separation activities, legal, income tax, audit and other consulting fees, insurance provisions and net financial charges related to debt issued and held in escrow. For the years ended December 31, 2024 and 2023, Liquids Pipelines business separation costs of $197 million ($167 million after tax) and $40 million ($34 million after tax), respectively, were included in Net income (loss) from discontinued operations, net of tax in the Consolidated statement of income. There were no separation costs recognized for the year ended December 31, 2025.

**Pensions**

As part of the Spinoff Transaction, certain TC Energy employees became employees of South Bow. Prior to the Spinoff Transaction, these employees in Canada and the U.S. participated in DB Plans, DC Plans and savings plans, as applicable. Effective October 1, 2024, the benefit obligations under the DB Plans in respect of the employees moving from TC Energy to South Bow were transferred to South Bow. An asset transfer application related to the Canadian DB Plan outlining the proposed transfer of assets from TC Energy to South Bow has received regulatory approval. During the year ended December 31, 2025, $105 million was transferred to South Bow. As at December 31, 2025, $17 million of assets in the Canadian DB Plan remain in the TC Energy DB Plan trust and are reflected as Current assets of discontinued operations with a corresponding obligation to South Bow reflected as Current liabilities of discontinued operations on the Consolidated balance sheet. The Company expects the remaining assets to be fully transferred mid-2026. As at December 31, 2024, the assets related to the U.S. DB Plan were fully transferred to South Bow.

**South Bow Debt**

On August 28, 2024, South Bow Canadian Infrastructure Holdings Ltd. and 6297782 LLC, two wholly-owned subsidiaries of the Company at the time, completed an offering of approximately $7.9 billion Canadian-dollar equivalent of senior unsecured notes and junior subordinated notes. Approximately $6.2 billion Canadian-dollar equivalent of the net proceeds was placed in escrow pending the completion of the Spinoff Transaction on October 1, 2024 and US$1.3 billion of senior unsecured notes were used to repay a TransCanada PipeLines Limited (TCPL) term loan. Upon completion of the Spinoff Transaction, the escrowed funds were released to South Bow and used to repay indebtedness owed by South Bow and its subsidiaries to TC Energy and its subsidiaries.

**Presentation of Discontinued Operations**

As described in Note 2, Accounting policies, upon completion of the Spinoff Transaction, the Liquids Pipelines business was accounted for as discontinued operations. The Company's presentation of discontinued operations includes revenues and expenses directly attributable to the Liquids Pipelines business.

Prior year comparatives present the Liquids Pipelines business as discontinued operations.

1During the year ended December 31, 2025, $21 million (2024 – $41 million) of revenues were recognized, which were included in contract liabilities and long-term contract liabilities at the beginning of the year.

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**

As at December 31, 2025, future revenues from long-term pipeline capacity arrangements and transportation as well as natural gas storage and other contracts extending through 2055 are approximately $33.8 billion, of which approximately $7.0 billion is expected to be recognized in 2026.

A significant portion of the Company's revenues are not included in the future revenue disclosure above, as the Company has elected the following disclosure exemptions:

• revenues related to flow-through operating costs, or other similar variable consideration, that are recognized at the amount for which the Company has the right to invoice the customer

• variable consideration relating to interruptible transportation service revenues and power generation revenues where there is uncertainty in estimating the amount of future revenue

• revenues for periods extending beyond the current rate settlement term for the Company's U.S. natural gas pipelines' regulated transportation and storage contracts where the maximum tariff rate is to be collected from shippers

• revenues for periods extending beyond the current rate settlement term for the Company's Canadian natural gas pipelines' regulated firm capacity contracts

• revenues related to assets under construction, which are recognized when the asset is placed in service.

**As a Lessor**

**Operating Leases**

The Grandview and Bécancour power plants in the Power and Energy Solutions segment are accounted for as operating leases. The Company has long-term PPAs for the sale of power from these assets which expire between 2026 and 2035.

Some operating leases contain variable lease payments that are based on operating hours and the reimbursement of variable costs, and options to purchase the underlying asset at fair value or based on a formula considering the remaining fixed payments. Lessees have rights under some leases to terminate under certain circumstances.

The fixed portion of the operating lease income recorded by the Company for the year ended December 31, 2025 was &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;$109 million (2024 – $114 million; 2023 – $112 million).

Future lease payments to be received under operating leases are as follows:

At December 31, 2025, the cost and accumulated depreciation for facilities accounted for as operating leases was $697 million and $371 million, respectively (2024 – $697 million and $351 million, respectively).

**Sales-Type Leases**

The Tamazunchale, Villa de Reyes, Tula and Southeast Gateway pipelines are part of a U.S. dollar-denominated take-or-pay Transportation Service Agreement (TSA) that extends through 2055 between TGNH and the Comisión Federal de Electricidad (CFE).

The consolidated TSA contains multiple lease and non-lease components. The lease components within the TSA represent the capacity available to the CFE provided by the in-service pipelines within TGNH at December 31, 2025. The non-lease components represent the Company's services with respect to operation and maintenance of the TGNH pipelines in service. The Company allocated a portion of the contract consideration to non-lease components for the provision of operating and maintenance services based on the stand-alone selling price using an expected cost plus margin approach. The remaining consideration was allocated to the lease components using the residual approach due to uncertainty surrounding the stand-alone selling price.

TC Energy **Consolidated Financial Statements** 2025 \| 163

***Transportadora de Gas Natural de la Huasteca***

In September 2025, TC Energy entered into a factoring arrangement with the CFE and a major domestic bank in Mexico to factor monthly invoices for services provided on the TGNH system in 2025. Invoices for August to October were factored to the bank without recourse to TC Energy and TC Energy continued to receive invoiced amounts within the contractual payment period.

The factoring arrangement resulted in a lease modification for accounting purposes of the existing TGNH TSA with the CFE, with no change to the lease classification upon reassessment. As such, the Company reallocated contract consideration to the lease and non-lease components of the contract using an expected cost plus margin approach based on the updated operating and maintenance services stand-alone selling price for each non-lease component as of the date of modification. The residual amount of consideration from this process was then allocated to the lease component. The change in allocation was accounted for prospectively. The rate implicit in the lease was adjusted to the rate at which the modified net investment in lease equaled the carrying value of the net investment in lease directly prior to the effective date of the modification.

Under lease accounting, TC Energy recorded factored amounts in Accounts payable and other, and the corresponding receivables were not derecognized on the Consolidated balance sheet. Cash received from the factoring arrangement were included in Financing activities in the Consolidated statement of cash flows. During 2025, TC Energy assigned and received payment for receivables having an aggregate face value of $351 million (US$251 million).

***Southeast Gateway Pipeline***

During second quarter 2025, the Company announced the completion of the Southeast Gateway pipeline. The Company determined that the pipeline is a sales-type lease between TGNH and the CFE that commenced when the asset was made available to the customer. At the inception of the agreement in 2022 and as revised in third quarter 2025 when the Company entered into a factoring arrangement with the CFE, the Company allocated the expected contract consideration to the non-lease component for the provisioning of operating and maintenance services based on the estimated stand-alone selling price using an expected cost plus margin approach. The residual amount of consideration from this process was then allocated to the lease component. The Company's estimate of future operating costs influenced the allocation of contract consideration between lease and non-lease components, the timing of income recognized under the contract and the calculation of the rate implicit in the lease.

The TGNH pipelines, which includes the Southeast Gateway pipeline, are rate-regulated and the tolls are designed to recover the cost of providing service. On this basis, the Company applied judgment to determine that, at the inception of the lease arrangement, the fair value of the underlying assets approximated the carrying value and the residual value approximated the remaining carrying value at the end of the lease term. The fair value was a non-recurring measurement classified in Level III of the fair value hierarchy. The Company estimated that if the assets were purchased at their carrying value, they would yield a return to the purchaser that is in line with current market participant expectations.

During 2025, the Company recorded a net investment in lease of $6.6 billion (US$4.8 billion) associated with the Southeast Gateway pipeline lease commencement, with no selling profit or losses recorded upon derecognition of the underlying asset. The Company recorded an expected credit loss provision of $113 million in Plant operating costs and other, relating to the initial net investment in lease balance.

Future lease payments to be received under the existing sales-type leases are as follows:

---

The contribution and repayment were included in Investing activities in the Consolidated statement of cash flows. Refer to Note 11, Loans with affiliates, for additional information.

**Coastal GasLink Pipeline Limited Partnership**

In November 2024, Coastal GasLink Pipeline Limited Partnership (Coastal GasLink LP) executed a commercial agreement with LNG Canada (LNGC) and each of the five LNGC participants (LNGC Participants) that declared commercial in-service for the Coastal GasLink pipeline, enabling toll collection from customers retroactive to October 1, 2024. The agreement also provided for a one-time payment of $199 million from LNGC Participants to TC Energy in recognition of completed work and final cost settlement, payable upon the earlier of three months following the LNG facility's declared in-service date or December 15, 2025.

Effective July 12, 2025, the LNG facility was declared in-service by LNGC. Pursuant to the commercial agreement, TC Energy received the one-time payment of $199 million, settled through a cash distribution in October 2025. This payment, which accrues entirely to TC Energy under the contractual arrangements between the Coastal GasLink LP partners, was recognized as an in-substance distribution from Coastal GasLink LP and reflected in Accounts receivable and Equity investments on the Company's Consolidated balance sheet as at December 31, 2024.

The Coastal GasLink project reached mechanical completion in November 2023 and was ready to deliver commissioning gas to the LNGC facility by the end of 2023. These milestones entitled Coastal GasLink LP to receive a $200 million incentive payment from LNGC, which was recorded as Accounts receivable on the Consolidated balance sheet and Income (loss) from equity investments in the Consolidated statement of income as at and for the year ended December 31, 2023. The incentive payment was settled through a cash distribution in February 2024.

In February 2023, Coastal GasLink LP announced an increase in the revised capital cost of the Coastal GasLink pipeline. The increase in project costs and the expectation that additional equity contributions under the subordinated loan agreement would be predominantly funded by TC Energy was an indication of significant adverse impact on the estimated fair value of the Company's investment in Coastal GasLink LP. The Company completed valuation assessments and concluded that the fair value of its investment in Coastal GasLink LP was below its carrying value, which resulted in a pre-tax impairment charge of $2,100 million in 2023 and cumulative impairment charges of $5,148 million, or $4,586 million after tax, between December 31, 2022 and September 30, 2023. No further indication of other-than-temporary impairments of the Company's investment in Coastal GasLink LP have since been identified and no further impairment charges have been recorded.

At December 31, 2025, the carrying value of the Company's investment in Coastal GasLink LP was $896 million (2024 – $1,006 million).

At December 31, 2025, the cumulative carrying value of the Company's equity investments was $834 million (2024 – $769 million) lower than the cumulative underlying equity in the net assets primarily due to the impairment of the equity investment in Coastal GasLink LP, partially offset by fair value adjustments at the time of acquisition or partial disposition, as well as interest capitalized during construction.

**11. LOANS WITH AFFILIATES**

Related party transactions are conducted in the normal course of business and are measured at the exchange amount, which is the amount of consideration established and agreed to by the related parties.

**Coastal GasLink Pipeline Limited Partnership**

TC Energy holds a 35 per cent equity interest in Coastal GasLink LP and operates the Coastal GasLink pipeline.

**Subordinated Loan Agreement**

TC Energy has a subordinated loan agreement with Coastal GasLink LP under which the Company advances non-revolving loans at floating market-based interest rates to Coastal GasLink LP to fund capital costs associated with the Coastal GasLink Pipeline project.

Coastal GasLink LP partners, including TC Energy, are contractually obligated to contribute equity to Coastal GasLink LP to ultimately fund the settlement of amounts outstanding under the subordinated loan agreement, with an expectation that such equity will predominantly be contributed by TC Energy. Because of this expectation, amounts drawn under the subordinated loan agreement have been accounted for as in-substance equity contributions, presented as Contributions to equity investments in the Company's Consolidated statement of cash flows. Repayments of amounts owed by Coastal GasLink LP to the Company have been accounted for as in-substance equity distributions, presented in Other distributions from equity investments in the Company's Consolidated statement of cash flows.

On December 17, 2024, following the declared commercial in-service of the pipeline, Coastal GasLink LP repaid the $3,147 million balance owing to TC Energy under the subordinated loan agreement. The Company's share of equity contributions required to fund Coastal GasLink LP's repayment of the outstanding loan balance amounted to $3,137 million. Unused committed capacity available for use by Coastal GasLink LP at December 31, 2025 was $163 million (December 31, 2024 – $228 million).

**Subordinated Demand Revolving Credit Facility Agreement**

The Company has a subordinated demand revolving credit facility agreement with Coastal GasLink LP to provide additional &nbsp;&nbsp;&nbsp;&nbsp;short-term liquidity and funding flexibility to projects under construction. Facilities available through this agreement bear interest at floating market-based rates and have a combined capacity of $120 million at December 31, 2025 and 2024 with no outstanding balances at December 31, 2025 and 2024.

**Sur de Texas**

TC Energy holds a 60 per cent equity interest in a joint venture with IEnova Infraestructura Marina Holding B.V. (IEnova) to own the Sur de Texas pipeline, operated by TC Energy.

**12. RATE-REGULATED BUSINESSES**

TC Energy's businesses that apply RRA currently include almost all of the Canadian, U.S. and Mexico natural gas pipelines and certain U.S. natural gas storage operations. Rate-regulated businesses account for and report assets and liabilities consistent with the resulting economic impact of the established rates, provided the rates are designed to recover the costs of providing the service and the competitive environment makes it probable that such rates can be charged and collected. Certain revenues and expenses subject to utility regulation or rate determination that would otherwise be reflected in the statement of income are deferred on the balance sheet and are expected to be recovered from or refunded to customers in future service rates.

**Canadian Regulated Operations**

The majority of TC Energy's Canadian natural gas pipelines are regulated by the CER under the Canadian Energy Regulator Act. The CER regulates the construction and operation of facilities and the terms and conditions of services, including rates, for the Company's Canadian regulated natural gas transmission systems under federal jurisdiction. The Impact Assessment Agency of Canada continues to assess designated projects.

TC Energy's Canadian natural gas transmission services are supplied under natural gas transportation tariffs that provide for cost recovery, including return of and on capital as approved by the CER. Subject to the terms of any settlement, rates charged for these services are typically set through a process that involves filing an application with the regulator wherein forecasted operating costs, including a return of and on capital, determine the revenue requirement for the upcoming year or multiple years. To the extent actual costs and revenues are more or less than forecasted costs and revenues, the regulator generally allows the difference to be deferred to a future period and recovered or refunded in rates at that time. Differences between actual and forecasted costs that the regulator does not allow to be deferred are included in the determination of net income in the year they occur. The Company's most significant regulated Canadian natural gas pipelines, based on total operated pipe length, are described below.

**NGTL System**

The NGTL System currently operates under the terms of the 2025-2029 Revenue Requirement Settlement, which was approved by the CER in September 2024 (the 2025-2029 NGTL Settlement). The 2025-2029 NGTL Settlement enables an investment framework that supports the approval by the Company's Board of Directors (Board) to allocate up to $3.3 billion of capital towards progression of the Multi-Year Growth Plan for expansion facilities to meet commitments on the NGTL System. It is comprised of multiple distinct projects with various targeted in-service dates, beginning in 2026, subject to final Company and regulatory approvals.

The 2025-2029 NGTL Settlement maintains an ROE of 10.1 per cent on 40 per cent deemed common equity while increasing NGTL System depreciation rates, with an incentive that allows the NGTL System the opportunity to further increase depreciation rates if tolls fall below specified levels or if growth projects are undertaken. The 2025-2029 NGTL Settlement introduces a new incentive mechanism to reduce both physical emissions and emission compliance costs, which builds on the incentive mechanism for certain operating costs where variances from projected amounts and emissions savings are shared with customers. A provision for review exists in the 2025-2029 NGTL Settlement if tolls exceed a pre-determined level or if final Company approvals of the multi-year growth plan are not obtained.

NGTL System's 2023 and 2024 results reflected the terms of the 2020-2024 Revenue Requirement Settlement which included an approved ROE of 10.1 per cent on 40 per cent deemed common equity, provided the NGTL System the opportunity to increase depreciation rates if tolls fell below specified levels and provided an incentive mechanism for certain operating costs where variances from projected amounts were shared with its customers.

**Canadian Mainline**

In April 2020, the CER approved the six-year unanimous negotiated settlement (the 2021-2026 Mainline Settlement) effective January 1, 2021. Similar to the previous settlement, the 2021-2026 Mainline Settlement maintains a base equity return of &nbsp;&nbsp;&nbsp;&nbsp;10.1 per cent on 40 per cent deemed common equity and includes an incentive to either achieve cost efficiencies and/or increase revenues on the pipeline with a beneficial sharing mechanism to both customers and TC Energy.

Toll stabilization is achieved using deferral accounts, including the toll-stabilization account and the short-term adjustment accounts (STAA), which capture the surplus or shortfall between system revenues and cost of service each year under the 2021-2026 Mainline Settlement. A portion of the STAA commenced amortization in 2023 and the remainder commenced amortization in 2024, according to the terms outlined in the 2021-2026 Mainline Settlement as predetermined thresholds per the settlement agreement were met.

**U.S. Regulated Operations**

TC Energy's U.S. regulated natural gas pipelines operate under the provisions of the Natural Gas Act of 1938 (NGA), the Natural Gas Policy Act of 1978 and the Energy Policy Act of 2005, and are subject to the jurisdiction of FERC. The NGA grants FERC authority over the construction, acquisition and operation of pipelines and related facilities, including the regulation of tariffs which incorporates maximum and minimum rates for services and allows U.S. regulated natural gas pipelines to discount or negotiate rates on a non-discriminatory basis. The Company's most significant regulated U.S. natural gas pipelines, based on effective ownership and total operated pipe length, are described below.

**Columbia Gas**

Columbia Gas' natural gas transportation and storage services are provided under a tariff at rates subject to FERC approval. Columbia Gas operates under a settlement approved by FERC in October 2025 (the 2025 Columbia Gas Settlement). As part of the settlement, there is a moratorium on any further rate changes until April 1, 2028, and Columbia Gas must file for new rates with an effective date no later than April 1, 2031. The settlement also included additional rate step ups in April 2026 and April 2027 to reflect anticipated modernization-related spend.

**ANR Pipeline**

ANR Pipeline operates under rates established through a 2022 FERC-approved rate settlement (the 2022 ANR Settlement). In 2023, previously accrued rate refund liabilities, including interest, were refunded to customers. The 2022 ANR Settlement included a moratorium on rate changes until November 1, 2025, and required ANR to file for new rates with an effective date no later than August 1, 2028. The settlement also provided for a rate step up effective August 2024 related to certain modernization projects and an additional rate step up effective no later than August 1, 2028. In April 2025, ANR filed a Section 4 Rate Case with FERC requesting an increase to maximum transportation rates effective November 1, 2025, subject to refund. As of December 31, 2025, ANR is pursuing a collaborative process to find a mutually beneficial outcome with customers.

**Columbia Gulf**

Columbia Gulf operates under a settlement approved by FERC in August 2023, effective March 1, 2024 (the 2023 Columbia Gulf Settlement). The 2023 Columbia Gulf Settlement includes a moratorium on further rate changes through February 28, 2027, and Columbia Gulf must file for new rates no later than March 1, 2029.

**Great Lakes**

Great Lakes operates under a rate settlement approved by FERC in April 2022 (the 2022 Great Lakes Settlement), which maintains Great Lakes' existing maximum transportation rates through October 31, 2025. The 2022 Great Lakes Settlement contained a moratorium until October 31, 2025. In April 2025, Great Lakes filed a Section 4 Rate Case with FERC requesting an increase to maximum transportation rates effective November 1, 2025, subject to refund. As of December 31, 2025, Great Lakes is pursuing a collaborative process to find a mutually beneficial outcome with customers.

**Tuscarora**

Tuscarora operates under rates established as part of the FERC-approved rate settlement in September 2023 (the 2023 Tuscarora Settlement). The 2023 Tuscarora Settlement provided for phased rate reductions as of February 1, 2023, and additionally as of February 1, 2025. The 2023 Tuscarora Settlement contains a moratorium that expires December 1, 2028. Tuscarora is required to file new rates by December 1, 2028.

**Gas Transmission Northwest**

Gas Transmission Northwest (GTN) operates under rates established as part of the FERC-approved rate settlement in October 2024 (the 2024 GTN Settlement). The 2024 GTN Settlement maintains the currently effective rates (the pre-filed rates) from April 1, 2024, through March 31, 2026. GTN will then reduce its pre-filed rates starting on April 1, 2026, through &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;March 31, 2027. The 2024 GTN Settlement contains a moratorium that expires March 31, 2027. GTN is required to file new rates by April 1, 2027.

**Mexico Regulated Operations**

TC Energy's natural gas pipelines in Mexico are regulated by the CNE. While the majority of the Company's capacity is subscribed under a long-term contractual rate, the CNE sets rates for interruptible services. The rates in effect on TC Energy's Mexico natural gas pipelines provide for cost recovery, including a return of and on invested capital.

1These regulatory assets and liabilities are underpinned by non-cash transactions or are recovered without an allowance for return as approved by the regulator. Accordingly, these regulatory assets or liabilities are not included in rate base and do not yield a return on investment during the recovery period.

2Operating and debt-service regulatory assets and liabilities represent the accumulation of cost and revenue variances to be included in determination of rates in the following year.

3Foreign exchange on long-term debt of the NGTL System represents the variance resulting from revaluing foreign currency-denominated debt instruments to the current foreign exchange rate from the historical foreign exchange rate at the time of issue. Foreign exchange gains and losses realized when foreign debt matures or is redeemed early are expected to be recovered or refunded through the determination of future tolls.

4This balance represents the amounts collected in tolls from customers and is included in the LMCI restricted investments to fund future abandonment of the Company's CER-regulated pipeline facilities.

5The U.S. corporate income tax rate was reduced from 35 per cent to 21 per cent in 2017 as a result of H.R.1, the Tax Cuts and Jobs Act (U.S. Tax Reform). This U.S. regulated operations balance, where applicable, represents established regulatory liabilities driven by 2018 FERC prescribed changes related to U.S. Tax Reform being amortized over varying terms that approximate the expected reversal of the underlying deferred tax liabilities that gave rise to the regulatory liabilities.

6These regulatory accounts are used to capture revenue and cost variances plus toll-stabilization adjustments during the 2015-2030 settlement term.

7Under the terms of the 2021-2026 Mainline Settlement, a portion of the STAA account commenced amortization in 2023 and the remainder commenced amortization in 2024, as predetermined thresholds were met, over the terms outlined per the settlement agreement.

8This balance represents anticipated costs of removal that have been, and continue to be, included in depreciation rates and collected in the service rates of certain rate-regulated operations for future costs to be incurred.

9These balances represent the regulatory offset to pension plan and other post-retirement benefit obligations to the extent the amounts are expected to be collected from or refunded to customers in future rates.

10This balance represents the amount ANR estimates it would be required to refund to its customers for post-retirement and post-employment benefit amounts collected through its FERC-approved rates that have not been used to pay benefits to its employees. Pursuant to a FERC-approved rate settlement, the $43 million (US$32 million) balance at December 31, 2025 is subject to resolution through future regulatory proceedings and, accordingly, a settlement period cannot be determined at this time.

11Under the terms of the 2021-2026 Mainline Settlement, $223 million is amortized over the six-year settlement term.

Changes in Goodwill were as follows:

| Foreign exchange rate changes | **(654)** |
| **Balance at December 31, 2025** | **13016** |

---

As part of the annual goodwill impairment assessment at December 31, 2025, the Company evaluated qualitative factors impacting the fair value of the underlying reporting units for all reporting units other than the Columbia reporting unit. It was determined that it was more likely than not that the fair value of all reporting units exceeded their carrying amounts, including goodwill.

**Columbia** 

The Company elected to proceed directly to a quantitative annual impairment test at December 31, 2025 for the $10,082 million (US$7,351 million) of goodwill related to the Columbia reporting unit subsequent to the 2025 Columbia Gas Settlement. To determine fair value, the Company used a discounted cash flow model incorporating projections of future cash flows as well as a valuation multiple and applied a risk-adjusted discount rate which involved significant estimates and judgments. The fair value measurement is classified as Level III in the fair value hierarchy. It was determined that the fair value of the Columbia reporting unit exceeded its carrying value, including goodwill, at December 31, 2025.

**Great Lakes**

The estimated fair value of the Great Lakes reporting unit in excess of its carrying value was less than 10 per cent at the date of the last quantitative goodwill impairment test in 2022. Any future reductions in cash flow forecasts or adverse changes in other key assumptions could result in a future impairment of the goodwill balance.

TC Energy's practice is to recognize interest and penalties related to income tax uncertainties in Income tax expense. Income tax expense for the year ended December 31, 2025 reflects $7 million interest expense (2024 – $1 million recovery; 2023 – $3 million expense). At December 31, 2025, the Company accrued $26 million in interest expense (2024 – $19 million; 2023 – $20 million). The Company incurred no penalties associated with income tax uncertainties related to income tax expense for the years ended December 31, 2025, 2024 and 2023 and no penalties were accrued as at December 31, 2025, 2024 and 2023.

The Company has substantially concluded all Canadian federal and provincial income tax matters for the years through 2017. Substantially all material U.S. federal, state and local income tax matters have been concluded for years through 2019. Substantially all material Mexico income tax matters have been concluded for years through 2019.

In October 2024, TCPL commenced and completed its 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, the Company repaid and retired outstanding callable notes at par. These extinguishments of debt resulted in a pre-tax net gain of $228 million, primarily due to the fair value discount and recognition of unamortized debt issue costs related to these notes. The net gain on debt extinguishment was recorded in Interest expense in the Consolidated statement of income.

1The effective interest rate is calculated by discounting the expected future interest payments using the coupon rate and any estimated future rate resets, adjusted for issue costs and discounts.

2In May 2025, TCPL exercised its option to fully repay and retire the US$750 million junior subordinated notes that had a maturity date of 2075.

3The junior subordinated notes were issued to TransCanada Trust (the Trust), a financing trust subsidiary wholly-owned by TCPL. While the obligations of the Trust are fully and unconditionally guaranteed by TCPL on a subordinated basis, the Trust is not consolidated in TC Energy's financial statements since TCPL does not have a variable interest in the Trust and the only substantive assets of the Trust are junior subordinated notes of TCPL.

4The coupon rate is initially a fixed interest rate for the first 10 years and converts to a floating rate thereafter.

5The coupon rate is initially a fixed interest rate for the first five years and resets every five years thereafter, subject to a rate-reset minimum.

6The coupon rate is initially a fixed interest rate for the first five years and resets every five years thereafter.

7Junior subordinated notes of US$1.0 billion were issued in 2007 at a fixed rate of 6.35 per cent and converted in 2017 to bear interest at a floating rate.

8The coupon rate is initially a fixed interest rate for the first 10 years and resets every five years thereafter.

**Junior Subordinated Notes Issued**

The Junior subordinated notes are subordinated in right of payment to existing and future senior indebtedness of TCPL.

In October 2025, TCPL issued US$370 million of junior subordinated notes maturing in 2085 with a fixed interest rate of 6.25 per cent. The junior subordinated notes are callable at TCPL's option at any time on or after November 1, 2030 at 100 per cent of the principal amount plus accrued and unpaid interest to the date of redemption.

In August 2025, TCPL issued $1.0 billion of junior subordinated notes maturing in 2056 with a fixed interest rate of 5.20 per cent per year until February 15, 2031. The rate on the junior subordinated notes will reset every five years commencing February 2031 until February 2056 to the then Five-Year Government of Canada Yield, as defined in the document governing the subordinated notes, plus 2.148 per cent per annum, subject to a rate-reset minimum. The junior subordinated notes are callable at TCPL's option at any time from November 15, 2030 to February 15, 2031 and on each interest payment and reset date thereafter at 100 per cent of the principal amount plus accrued and unpaid interest to the date of redemption.

In February 2025, TCPL issued US$750 million of junior subordinated notes maturing in 2065 with a fixed interest rate of 7.00 per cent per year until June 1, 2030, and resetting every five years thereafter. The rate on the junior subordinated notes will reset every five years commencing June 2030 until June 2065 to the then Five-Year Treasury Rate, as defined in the document governing the subordinated notes, plus 2.614 per cent per annum. The junior subordinated notes are callable at TCPL's option at any time from March 1, 2030 to June 1, 2030 and on each interest payment and reset date thereafter at 100 per cent of the principal amount plus accrued and unpaid interest to the date of redemption.

Pursuant to the terms of the junior subordinated notes issued in 2025, TCPL has the option to defer payment of interest for one or more periods of up to ten years without giving rise to an event of default and without permitting acceleration of payment. TC Energy and TCPL would be prohibited from declaring or paying dividends during any deferral period.

**Junior Subordinated Notes Retired/Repaid**

In May 2025, TCPL exercised its option to fully repay and retire the US$750 million junior subordinated notes that had a maturity date of 2075, bearing interest at 5.88 per cent to TransCanada Trust (the Trust). The related unamortized debt issue costs of $11 million were included in Interest expense in the Consolidated statement of income. All of the proceeds from the repayment were used by the Trust to fund the redemption price of the US$750 million in aggregate principal amount of outstanding Trust Notes - Series 2015-A, in May 2025 pursuant to their terms.

**Common Shares Issued and Outstanding**

The Company is authorized to issue an unlimited number of common shares without par value.

**Common Shares After Spinoff Transaction**

On October 1, 2024, as part of the Spinoff Transaction, TC Energy shareholders received one new TC Energy common share &nbsp;&nbsp;&nbsp;&nbsp;and 0.2 of a South Bow common share in exchange for each TC Energy common share held.

**Dividend Reinvestment and Share Purchase Plan**

Under the Company's Dividend Reinvestment and Share Purchase Plan (DRP), eligible holders of common and preferred shares of TC Energy can reinvest their dividends and make optional cash payments to obtain additional TC Energy common shares. From August 31, 2022 to July 31, 2023, common shares were issued from treasury at a discount of two per cent to market prices over a specified period.

After July 31, 2023, common shares purchased with reinvested cash dividends under TC Energy's DRP are acquired on the open market at 100 per cent of the weighted average purchase price.

**Basic and Diluted Net Income (Loss) per Common Share**

Net income (loss) from continuing operations per common share is calculated by dividing Net income (loss) from continuing operations attributable to common shares by the weighted average number of common shares outstanding. Net income (loss) from discontinued operations is calculated by dividing Net income (loss) from discontinued operations by the weighted average number of common shares outstanding. The weighted average number of shares for the diluted earnings per share calculation includes options exercisable under TC Energy's Stock Option Plan and, from August 31, 2022 to July 31, 2023, common shares issuable from treasury under the DRP.

1 &nbsp;&nbsp;&nbsp;&nbsp;Exercise prices of TC Energy stock options were adjusted in 2024 for the change in value of the TC Energy common shares following the Spinoff Transaction.

At December 31, 2025, an additional 3,994,688 common shares were reserved for future issuance from treasury under TC Energy's Stock Option Plan. The contractual life of options granted is seven years. Options may be exercised at a price determined at the time the option is awarded and vest equally on the anniversary date in each of the three years following the award. Forfeiture of stock options results from their expiration and, if not previously vested, upon resignation or termination of the option holder's employment. Commencing in 2024, the Company no longer issues stock options to employees or officers. The Company used a binomial model for determining the fair value of options granted and applied the following weighted average assumptions:

---

| | |
|:---|:---|
| **year ended December 31** | **2023** |
| Weighted average fair value | $7.88 |
| Expected life (years)<sup>1</sup> | 5.1 |
| Interest rate | 2.9% |
| Volatility<sup>2</sup> | 24% |
| Dividend yield | 6.3% |

---

1Expected life is based on historical exercise activity.

2Volatility is derived based on the average of both the historical and implied volatility of the Company's common shares.

The amount expensed for stock options, with a corresponding increase in Additional paid-in capital, was $7 million in 2025 (2024 – $6 million; 2023 – $9 million). At December 31, 2025, unrecognized compensation costs related to non-vested stock options were $0.8 million and are expected to be fully recognized over a period of 0.1 years.

The following table summarizes additional stock option information:

---

| | | | |

| Total intrinsic value of options exercised | **20** | 17 |  |
| Total fair value of options that have vested | **62** | 99 | 76 |
| Total options vested | **0.8 million** | 1.5 million | 1.5 million |

---

As at December 31, 2025, the aggregate intrinsic values of the total options exercisable and the total options outstanding were $23 million and $34 million, respectively (2024 - $20 million and $34 million, respectively).

**Shareholder Rights Plan**

TC Energy's Shareholder Rights Plan is designed to provide the Board of Directors with sufficient time to explore and develop alternatives for maximizing shareholder value in the event of a takeover offer for the Company and to encourage the fair treatment of shareholders in connection with any such offer. Attached to each common share is one right that, under certain circumstances, entitles certain holders to purchase an additional common share of the Company.

**26. EMPLOYEE POST-RETIREMENT BENEFITS**

The Company sponsors DB Plans for certain employees. Pension benefits provided under the DB Plans are generally based on years of service and highest average earnings over three to five consecutive years of employment. Effective January 1, 2019, there were certain amendments made to the Canadian DB Plan for new members. Subsequent to that date, benefits provided for new members were based on years of service and highest average earnings over five consecutive years of employment. Upon commencement of retirement, pension benefits in the Canadian DB Plan increase annually by a portion of the increase in the Consumer Price Index for employees hired prior to January 1, 2019. On January 1, 2024 the Canadian DB Plans were closed to new entrants. Employees hired on and after January 1, 2024 will participate in the Canadian DC Plan.

On January 1, 2025, there was an amendment to the Canadian OPEB Plan which closed the plan for any eligible active employees that did not retire by December 31, 2024. All active employees who no longer meet the eligibility for the OPEB Plan will be eligible for a new plan that provides an annual health spending account to retirees and their dependents from retirement to age 65.

The Company's U.S. DB Plan is closed to non-union new entrants and all non-union hires participate in the DC Plan. Net actuarial gains or losses are amortized out of AOCI over the EARSL of Plan participants, which was approximately eight years at December 31, 2025 (2024 – nine years; 2023 – nine years).

The Company also provides its employees with DC Plans and savings plans in Canada, DC Plans in Mexico, DC Plans consisting of a 401(k) Plan in the U.S. and post-employment benefits other than pensions, including termination benefits and life insurance and medical benefits beyond those provided by government-sponsored plans. Net actuarial gains or losses for the plans are amortized out of AOCI over the EARSL of employees, which was approximately 11 years at December 31, 2025 (2024 – 12 years and 2023 – 12 years). In 2025, the Company expensed $72 million (2024 – $71 million and 2023 – $64 million) for the savings and DC Plans.

As part of the Spinoff Transaction, certain TC Energy employees became employees of South Bow. Prior to the Spinoff Transaction, these employees in Canada and the U.S. participated in DB Plans, DC Plans and savings plans, as applicable. Effective October 1, 2024, the benefit obligations under the DB Plans in respect of the employees moving from TC Energy to South Bow were transferred to South Bow. An asset transfer application related to the Canadian DB Plan outlining the proposed transfer of assets from TC Energy to South Bow has received regulatory approval. During the year ended December 31, 2025, $105 million was transferred to South Bow. As at December 31, 2025, $17 million of assets in the Canadian DB Plan remain in the TC Energy DB Plan trust and are reflected as Current assets of discontinued operations with a corresponding obligation to South Bow reflected as Current liabilities of discontinued operations on the Consolidated balance sheet. The Company expects the remaining assets to be fully transferred mid-2026. As at December 31, 2024, the assets related to the U.S. DB Plan were fully transferred to South Bow.

Total cash contributions by the Company for employee post-retirement benefits were as follows:

---

| | | | |
|:---|:---|:---|:---|
| **year ended December 31** | **2025** | **2024** | **2023** |

| Other post-retirement benefit plans | **8** | 8 | 9 |
| Savings and DC Plans | **72** | 71 | 64 |
|  | **80** | 79 | 101 |

---

Current Canadian pension legislation allows for partial funding of solvency requirements over a number of years through letters of credit in lieu of cash contributions, up to certain limits. Total letters of credit provided to the Canadian DB plan at December 31, 2025 was nil (2024 – $111 million; 2023 – $244 million).

The most recent actuarial valuation of the pension plans for funding purposes was as at January 1, 2025 and the next required valuation is at January 1, 2026.

1The benefit obligation for the Company's pension benefit plans represents the projected benefit obligation. The benefit obligation for the Company's other post-retirement benefit plans represents the accumulated post-retirement benefit obligation.

2The increase in the actuarial (gain) loss on the defined benefit plan obligation is primarily attributable to an increase in the weighted discount rate from 4.90 per cent in 2024 to 5.10 per cent in 2025 and an increase in the rate of return. The actuarial (gain) loss on the OPEB Plan obligation is primarily due to changes in demographic assumptions.

3Reflects the impact of the Spinoff Transaction of the Liquids Pipelines business on October 1, 2024.

4The Company reduced letters of credit by $111 million in the Canadian DB Plan (2024 – $133 million) for funding purposes.

5OPEB surplus of nil (2024 - $49 million) was transferred to pay future active employee medical expenses.

Pension plan assets are managed on a going concern basis, subject to legislative restrictions, and are diversified across asset classes to maximize returns at an acceptable level of risk. Asset mix strategies consider plan demographics and may include traditional equity and debt securities as well as alternative assets such as infrastructure, private equity, real estate and derivatives to diversify risk. Derivatives are not used for speculative purposes and may be used to hedge certain liabilities.

All investments are measured at fair value using market prices. Where the fair value cannot be readily determined by

reference to generally available price quotations, the fair value is determined by considering the discounted cash flows on

a risk-adjusted basis and by comparison to similar assets which are publicly traded. In Level I, the fair value of assets is determined by reference to quoted prices in active markets for identical assets that the Company has the ability to access at

the measurement date. In Level II, the fair value of assets is determined using valuation techniques such as option pricing

models and extrapolation using significant inputs which are observable directly or indirectly. In Level III, the fair value of

assets is determined using a market approach based on inputs that are unobservable and significant to the overall fair

value measurement.

The rate used to discount pension and other post-retirement benefit plan obligations was developed based on a yield curve of primarily corporate AA bond yields at December 31, 2025. This yield curve is used to develop spot rates that vary based on the duration of the obligations. The estimated future cash flows for the pension and other post-retirement benefit obligations were matched to the corresponding rates on the spot rate curve to derive a weighted average discount rate.

The significant weighted average actuarial assumptions adopted in measuring the Company's benefit obligations were as follows:

The overall expected long-term rate of return on plan assets is based on historical and projected rates of return for the portfolio in aggregate and for each asset class in the portfolio. Assumed projected rates of return are selected after analyzing historical experience and estimating future levels and volatility of returns. Asset class benchmark returns and asset mix are also considered in determining the overall expected rate of return. The discount rate is based on market interest rates of high-quality bonds that match the timing and benefits expected to be paid under each plan.

A 6.70 per cent weighted-average annual rate of increase in the per capita cost of covered health care benefits was assumed for 2026 measurement purposes. The rate was assumed to decrease gradually to 4.85 per cent by 2036 and remain at this level thereafter.

The net benefit cost recognized for the Company's pension benefit plans and other post-retirement benefit plans was as follows:

**27. RISK MANAGEMENT AND FINANCIAL INSTRUMENTS**

**Risk Management Overview**

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

Risk management strategies, policies and limits are designed to ensure TC Energy's risks and related exposures are in line with the Company's business objectives and risk tolerance. TC Energy's risks are managed within limits that are established by the Company's Board, implemented by senior management and monitored by the Company's risk management, internal audit and business segment groups. The Board's Audit Committee oversees how management monitors compliance with risk management policies and procedures and oversees management's review of the adequacy of the risk management framework.

**Market Risk**

The Company constructs and invests in energy infrastructure projects, purchases and sells commodities, issues short- and long-term debt, including amounts in foreign currencies and invests in foreign operations. Certain of these activities expose the Company to market risk from changes in commodity prices, foreign exchange rates and interest rates, which may affect the Company's earnings, cash flows and the value of its financial assets and liabilities. The Company assesses contracts used to manage market risk to determine whether all, or a portion, meets the definition of a derivative.

Derivative contracts the Company uses to assist in managing exposure to market risk may include the following:

• forwards and futures contracts – agreements to purchase or sell a specific financial instrument or commodity at a specified price and date in the future

• swaps – agreements between two parties to exchange streams of payments over time according to specified terms

• options – agreements that convey the right, but not the obligation of the purchaser to buy or sell a specific amount of a financial instrument or commodity at a fixed price, either at a fixed date or at any time within a specified period.

**Commodity price risk**

The following strategies may be used to manage the Company's exposure to market risk resulting from commodity price risk management activities in the Company's non-regulated businesses:

• in the Company's natural gas marketing business, TC Energy enters into natural gas transportation and storage contracts as well as natural gas purchase and sale agreements. The Company manages exposure on these contracts using financial instruments and hedging activities to offset market price volatility

• in the Company's power businesses, TC Energy manages the exposure to fluctuating commodity prices through long-term contracts and hedging activities including selling and purchasing electricity and natural gas in forward markets

• in the Company's non-regulated natural gas storage business, TC Energy's exposure to seasonal natural gas price spreads is managed with a portfolio of third-party storage capacity contracts and through offsetting purchases and sales of natural gas in forward markets to lock in future positive margins.

Lower natural gas and electricity prices could lead to reduced investment in the development, expansion and production of these commodities. A reduction in the demand for these commodities could negatively impact opportunities to expand the Company's asset base and/or re-contract with TC Energy's shippers and customers as contractual agreements expire.

**Physical and transition risks**

Climate-related physical and transition risks may influence demand for, or the operation of, TC Energy's assets, which could affect the Company's financial performance. TC Energy evaluates the financial resilience of its asset portfolio against a range of future pricing and supply and demand outcomes as part of the Company's strategic planning process.

TC Energy manages exposure to climate-related transition risks and resulting policy changes through its business model, which is based on a long-term, low-risk strategy whereby the majority of TC Energy's earnings are underpinned by regulated &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;cost-of-service arrangements and/or long-term contracts. Physical and transition risks are factored into capital planning, enterprise risk management, financial risk management and operational activities. In addition, the Company is actively working to reduce methane emissions intensity from our natural gas transmission and gas storage assets.

TC Energy **Consolidated Financial Statements** 2025 \| 199

------

**Interest rate risk**

TC Energy utilizes short- and long-term debt to finance its operations which exposes the Company to interest rate risk. TC Energy typically pays fixed rates of interest on its long-term debt and floating rates on short-term debt including its commercial paper programs and amounts drawn on its credit facilities. A small portion of TC Energy's long-term debt bears interest at floating rates. In addition, the Company is exposed to interest rate risk on financial instruments and contractual obligations containing variable interest rate components. The Company actively manages its interest rate risk using interest rate derivatives.

**Foreign exchange risk**

Certain of TC Energy's businesses generate all or most of their earnings in U.S. dollars and, since the Company reports its financial results in Canadian dollars, changes in the value of the U.S. dollar against the Canadian dollar can affect its net income. This exposure grows as the Company's U.S. dollar-denominated operations grow. A portion of this risk is offset by interest expense on U.S. dollar-denominated debt. The balance of the exposure is actively managed on a rolling basis up to three years in advance using foreign exchange derivatives; however, the natural exposure beyond that period remains.

A portion of the Company's Mexico Natural Gas Pipelines monetary assets and liabilities are peso-denominated, while TC Energy's Mexico operations' financial results are denominated in U.S. dollars. These peso-denominated balances are revalued to U.S. dollars and, as a result, changes in the value of the Mexican peso against the U.S. dollar can affect the Company's net 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 (loss) from equity investments and Income tax expense (recovery). These exposures are actively managed using foreign exchange derivatives, although some unhedged exposure remains.

**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 and cross-currency interest rate swaps as appropriate.

The fair values and notional amounts for the derivatives designated as a net investment hedge were as follows:

---

1Fair value equals carrying value.

2No amounts have been excluded from the assessment of hedge effectiveness.

3In 2025 and 2024, Net income (loss) included net realized gains of less than $1 million related to the interest component of cross-currency swap settlements which are reported within Interest expense in the Consolidated statement of income.

The notional amounts and fair values of U.S. dollar-denominated debt designated as a net investment hedge were as follows:

|:---|:---|:---|
| **at December 31** | **2025** | **2024** |

| Fair value | **25,800 (US 18,800)** | 25,700 (US 17,800) |

---

**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.

At times, the Company's counterparties may endure financial challenges resulting from commodity price and market volatility, economic instability and political or regulatory changes. In addition to actively monitoring these situations, there are a number of factors that reduce TC Energy's counterparty credit risk exposure in the event of default, including:

• contractual rights and remedies together with the utilization of contractually-based financial assurances

• current regulatory frameworks governing certain TC Energy operations

• the competitive position of the Company's assets and the demand for the Company's services

• potential recovery of unpaid amounts through bankruptcy and similar proceedings.

200 \| TC Energy **Consolidated Financial Statements** 2025

------

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.

The Company's net investment in leases and certain contract assets are financial assets subject to ECL. TC Energy's methodology for assessing the ECL regarding these financial assets includes consideration of the probability of default (the probability that the customer will default on its obligation), the loss given default (the economic loss as a proportion of the financial asset balance in the event of a default) and the exposure at default (the financial asset balance at the time of a hypothetical default) with one-year forward-looking information that includes assumptions for future macroeconomic conditions under three probability-weighted future scenarios.

The macroeconomic factors considered most relevant to the Company's net investment in leases and contract assets include Mexico's GDP, Mexico's government debt to GDP and Mexico's inflation. The ECL amount is updated at each reporting date to reflect changes in assumptions and forecasts for future economic conditions.

For the year ended December 31, 2025, the Company recorded an $84 million ECL expense (2024 – $23 million recovery; 2023 - $73 million recovery) with respect to the net investment in leases associated with the in-service TGNH pipelines and $1 million ECL recovery (2024 – $1 million expense; 2023 – $10 million recovery) for contract assets related to certain other Mexico natural gas pipelines. At December 31, 2025, the balance of the ECL provision was $141 million (2024 – $59 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 December 31, 2025 and 2024.

At December 31, 2025 and 2024, there were no significant credit risk concentrations and no significant 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.

**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.

**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 year-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.

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 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 Consolidated balance sheet.

1Amounts available for offset do not include cash collateral pledged or received.

With respect to the derivative instruments presented above, the Company provided cash collateral of $93 million and letters of credit of $73 million at December 31, 2025 (2024 – $133 million and $59 million, respectively) to its counterparties.&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;At December 31, 2025, the Company held less than $1 million in cash collateral and $102 million in letters of credit (2024 – less than $1 million and $75 million, respectively) from counterparties on asset exposures.

**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 December 31, 2025, the aggregate fair value of all derivative instruments with credit-risk-related contingent features that were in a net liability position was $5 million (2024 – net liability of $10 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 December 31, 2025, 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>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>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 with terms ranging from 15 to 20 years, to sell 50 MW of power 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 80 per cent from wind generation, 10 per cent from solar generation and 10 per cent from the market.

**U.S. Natural Gas Pipelines**

**Portland Natural Gas Transmission System (PNGTS)**

In August 2024, the Company and its partner, Northern New England Investment Company, Inc., a subsidiary of Énergir L.P. (Énergir), completed the sale of PNGTS to a third party for a gross purchase price of approximately $1.6 billion &nbsp;&nbsp;&nbsp;&nbsp;(US$1.1 billion), including the third party's assumption of US$250 million of senior notes outstanding at PNGTS, split pro rata according to the PNGTS ownership interests (TC Energy – 61.7 per cent, Énergir – 38.3 per cent). The Company's share of the proceeds was $743 million (US$546 million), net of transaction costs. The pre-tax gain attributable to the Company of &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;$572 million (US$408 million) was included in Net gain (loss) on sale of assets in the Consolidated statement of income, and the after-tax gain attributable to the Company was $456 million (US$323 million). The gain includes foreign currency translation gains of $15 million which were reclassified from AOCI to Net income (loss).

**Columbia Gas and Columbia Gulf**

In October 2023, TC Energy completed the sale of a 40 per cent non-controlling equity interest in Columbia Gas and Columbia Gulf to Global Infrastructure Partners (GIP) for proceeds of $5.3 billion (US$3.9 billion). The Company continues to have a controlling interest in these companies and will remain the operator of the pipelines. TC Energy and GIP will each fund their proportionate share of annual maintenance, modernization and sanctioned growth capital expenditures through internally generated cash flows, debt financing within the Columbia entities, or from proportionate contributions from TC Energy and GIP.

The sale was accounted for as an equity transaction of which $9.5 billion (US$6.9 billion) was recorded as non-controlling interests to reflect the 40 per cent change in the Company's ownership interest in Columbia Gulf and Columbia Gas. The difference between the non-controlling ownership interest recognized and the consideration received was recorded as a reduction to Additional paid-in capital of $3.5 billion (US$3.0 billion), net of tax and transaction costs for the year ended December 31, 2023.

At December 31, 2024, as part of the contingent consideration included in the sale, TC Energy accrued a one-time special distribution to GIP of $33 million (US$23 million), or $24 million (US$17 million) net of tax, in Additional paid-in capital.

For the year ended December 31, 2025, the Company recorded $348 million as an out-of-period adjustment to reclassify a pro rata portion of its net investment hedge losses from AOCI to NCI related to the sale of 40 per cent of Columbia Gas and Columbia Gulf on October 4, 2023. Refer to Note 2, Accounting policies, for additional information.

**Mexico Natural Gas Pipelines**

**Transportadora de Gas Natural de la Huasteca**

In second quarter 2024, in accordance with the terms of the Company's strategic alliance, and in exchange for cash and &nbsp;&nbsp;&nbsp;&nbsp;non-cash consideration of $561 million (US$411 million), the CFE became a partner in TGNH with a 13.01 per cent equity interest. The transaction was accounted for as an equity transaction, of which $588 million was recognized in Non-controlling interests and $21 million was recognized as AOCI attributable to the CFE's non-controlling interest. The difference between these amounts and the consideration received was recorded as a reduction to Additional paid-in capital of $27 million.

**Power and Energy Solutions**

**Texas Wind Farms**

In the first half of 2023, TC Energy acquired 100 per cent of the Class B Membership Interests in Fluvanna Wind Farm (Fluvanna) and Blue Cloud Wind Farm (Blue Cloud), respectively. Each of these operating assets has a tax equity investor which owns 100 per cent of the Class A Membership Interests, to which a percentage of earnings, tax attributes and cash flows are allocated. The tax equity investors' interests were recorded as non-controlling interests at their aggregate estimated fair value of $222 million (US$167 million).

TC Energy has determined that the use of the Hypothetical Liquidation at Book Value (HLBV) method of allocating earnings between the Company and the tax equity investors is appropriate as the earnings, tax attributes and cash flows from Fluvanna and Blue Cloud are allocated to its Class A and Class B Membership Interest owners on a basis other than ownership percentages.

Using the HLBV method, the Company's earnings from the projects are calculated based on how the projects would allocate and distribute cash if the net assets were sold at their carrying amounts on the reporting date under the provisions of the tax equity agreements.

TC Energy **Consolidated Financial Statements** 2025 \| 211

------

TC Energy determined it has a controlling financial interest in both projects and has consolidated the acquired entities as voting interest entities. The tax equity investors' interests were recorded as non-controlling interests at their estimated fair values of $106 million (US$80 million) for Fluvanna and $116 million (US$87 million) for Blue Cloud. These transactions are accounted for as asset acquisitions and therefore did not result in the recognition of goodwill.

**30. COMMITMENTS, CONTINGENCIES AND GUARANTEES**

**Commitments**

TC Energy and its affiliates have long-term natural gas transportation and natural gas purchase arrangements as well as other purchase obligations, all of which are transacted at market prices and in the normal course of business. Purchases under these contracts in 2025 were $340 million (2024 – $347 million; 2023 – $335 million).

The Company has entered into PPAs with solar and wind-power generating facilities with terms extending to 2038 that require the purchase of generated energy and associated environmental attributes. At December 31, 2025, the total planned capacity secured under the PPAs is approximately 750 MW with the generation subject to operating availability and capacity factors. These PPAs do not meet the definition of a lease or derivative. Future payments and their timing cannot be reasonably estimated as they are dependent on when certain underlying facilities are placed into service and the amount of energy generated. Certain of these purchase commitments have offsetting sale PPAs for all or a portion of the related output from the facility.

Capital expenditure commitments include obligations related to the construction of growth projects and are based on the projects proceeding as planned. Changes to these projects, including cancellation, would reduce or possibly eliminate these commitments as a result of cost mitigation efforts. At December 31, 2025, TC Energy had approximately $0.8 billion of capital expenditure commitments, primarily consisting of $0.6 billion for its U.S. natural gas pipelines, primarily related to construction costs associated with ANR and other pipeline projects.

**Contingencies**

TC Energy is subject to laws and regulations governing environmental quality and pollution control. At December 31, 2025, the Company had accrued approximately $6 million (2024 – $8 million) related to operating facilities, which represents the present value of the estimated future amount it expects to spend to remediate the sites. However, additional liabilities may be incurred as assessments take place and remediation efforts continue.

TC Energy and its subsidiaries are subject to various legal proceedings, arbitrations and actions arising in the normal course of business. The Company assesses all legal matters on an ongoing basis, including those of its equity investments, to determine if they meet the requirements for disclosure or accrual of a contingent loss.

The following contingencies were concluded during the year ended December 31, 2025:

**2016 Columbia Pipeline Acquisition Lawsuit**

In 2018, former shareholders of Columbia Pipeline Group Inc. (CPG) commenced a class action lawsuit related to the acquisition of CPG by TC Energy in 2016. In 2023, the Delaware Chancery Court (the Court) found that the former CPG executives breached their fiduciary duties, that the former CPG Board breached its duty of care in overseeing the sale process and that TC Energy aided and abetted those breaches. TC Energy's allocated share of damages was an estimated US$350 million, plus post-judgment interest. TC Energy appealed the decision to the Delaware Supreme Court and on June 17, 2025, the Supreme Court issued its decision reversing the Court's finding of liability against TC Energy. On July 10, 2025, the Court granted the final order vacating its prior judgment and dismissing plaintiffs' claims against TC Energy. As a result, this matter is now concluded in TC Energy's favour with no liability. There is no further right of appeal.

**Pacific Atlantic Pipeline Construction Ltd.**

Coastal GasLink LP and Pacific Atlantic Pipeline Construction Ltd., one of the prime contractors on the Coastal GasLink pipeline, and their parent company Bonatti S.p.A, have reached a mutually acceptable resolution to their disputes. The settlement is not an admission of liability by either party and the parties have mutually released their respective claims in the arbitration. Details of the arbitration and the settlement are confidential, but it does include the retention by Coastal GasLink LP of the letter of credit funds drawn in 2024 and the settlement did not have a material impact on TC Energy's financial statements.

Details of the arbitration and the settlement are confidential and the settlement did not have a material impact on TC Energy's financial statements.

**Guarantees**

2TC Energy is contractually obligated to fund the capital costs to complete the Coastal GasLink pipeline by funding the remaining equity requirements of Coastal GasLink LP through incremental capacity on the subordinated loan agreement with Coastal GasLink LP until final costs are determined. In December 2024, TC Energy made an equity contribution of $3,137 million to Coastal GasLink LP, which used the funds to repay the $3,147 million balance owing to TC Energy under the subordinated loan agreement. The repayment reduced the Company's funding commitment under the subordinated loan agreement to $228 million. In October 2025, TC Energy made an additional $65 million in equity contributions to Coastal GasLink LP, which reduced the Company's funding commitment under the subordinated loan agreement to $163 million. In addition to the subordinated loan agreement, TC Energy has entered into an equity contribution agreement to fund a maximum of $37 million for its proportionate share of the equity requirements related to the Cedar Link project.

This Policy is in addition to any other action or remedy available to the Company against such individuals under applicable law, policy or contract, up to and including termination of employment and/or legal action for breach of fiduciary duty or fraud. This Policy applies to all Covered Executives of TC Energy Corporation and their beneficiaries, heirs, executors, administrators or other legal representatives. Policy 1 Recoupment event 1.1 If TC Energy Corporation is required to prepare a Restatement, then, as determined by the Human Resources Committee, the Covered Executive's Incentive-Based Compensation will be subject to forfeiture, recovery and recoupment, subject to the following: a) This Policy applies to Incentive-Based Compensation received by a Covered Executive: (i) on or after October 2, 2023, (ii) after beginning services as a Covered Executive, and any subsequent changes in a Covered Executive's employment status, including retirement or termination of employment, do not affect the Company's rights to recoup Erroneously Awarded Compensation pursuant to this Policy, and (iii) if the Covered Executive served as a Covered Executive at any time during the performance period for such Incentive-Based Compensation. b) The amount to be forfeited or recouped will equal the Erroneously Awarded Compensation. The Human Resources Committee will take actions necessary to recoup the Erroneously Awarded Compensation reasonably promptly following a Restatement. Where the amount of Erroneously Awarded Compensation is not subject to

The Company will maintain documentation of the determination of that reasonable estimate and provide such documentation to the New York Stock Exchange (NYSE). The amount of the Erroneously Awarded Compensation must not be reduced based on, or otherwise calculated with regard to, any taxes paid by the Covered Executive with respect to such amounts. c) This Policy must only apply to Incentive-Based Compensation that was received during the Applicable Period and that was received (or would have been settled in the absence of an elective deferral of payment by the individual) while TC Energy Corporation has a class of securities listed on a U.S. national securities exchange or a national securities association. For purposes of this Policy, Incentive-Based Compensation is deemed received in the fiscal period during which the Financial Reporting Measure(s) specified in the applicable Incentive-Based Compensation is attained, even if the payment or grant of the Incentive-Based Compensation occurs after the end of such fiscal period. 1.2 In the event of a recoupment of Erroneously Awarded Compensation from a Covered Executive, the Human Resources Committee may also seek reimbursement of all reasonable costs, including legal fees, incurred in connection with the recoupment of the Erroneously Awarded Compensation from such Covered Executive. 2 Impracticability 2.1 The Company must recoup any Erroneously Awarded Compensation unless the conditions set forth in the following clauses (a), (b) or (c) are met and such recoupment would be impracticable, as determined by the Human Resources Committee in accordance with Rule 10D-1 and the NYSE Listing Standards. No recoupment will be required if: a) the direct expense paid to a third party to assist in enforcing this Policy would exceed the amount to be recouped, provided that before concluding that it would be impractical to recoup any amount of Erroneously Awarded Compensation based on this clause (a), the Company must make a reasonable attempt to recoup such Erroneously Awarded Compensation, document such reasonable attempt(s) and provide such documentation to the NYSE; b) recoupment would likely cause an otherwise tax-qualified retirement plan, under which benefits are broadly available to Employees of the Company, to fail to meet the applicable requirements of the U.S. Internal Revenue Code, or any successor provision thereof; or c) recoupment would violate home country law where that law was adopted prior to November 28, 2022, provided that before concluding that it would be impractical to recoup any amount of Erroneously Awarded Compensation based on this clause (c), the Company must obtain an opinion of home country legal counsel, acceptable to the NYSE, that recoupment would result in such violation, and must provide such opinion to the NYSE.

SAFETY IN EVERY STEP Protect myself, my teammates, the public and the environment Our commitment to safety isn't just a mantra – it's how we work 24/7, 365 days of the year across our entire organization. What started as a foundational value within our safety department decades ago has now come to mean much more to our Company. We ensure that when doing our work we put safety in every step to prevent all harm, loss and incidents. We expect all Personnel to share TC Energy's commitment to safety. Learning from both achievements and challenges is essential for continuous improvement and growth. By reflecting on successes we can replicate effective safety strategies, and analyzing setbacks allows us to avoid repeating mistakes. Whether you work in a field location or in an office setting, you must always ensure that you comply with all health, safety and environment related legal requirements, as well as the requirements set out by TC Energy in COBE and applicable policies. If it isn't safe, we won't do it. By reinforcing a disciplined set of rules and providing rigorous training, we approach everything we do with safety and performance at the forefront. We report all health, safety and environment related hazards, potential hazards, incidents, near hits and unsafe acts. We take every report seriously, investigate to identify facts and ensure immunity from disciplinary action for the Good Faith Reporting of all incidents and issues. QUESTION: I'm working on a big project and it's very important to the Company that it be completed on-time and on-budget. I'm concerned that I might be injured if I rush my work, but I'm feeling a lot of pressure to do so. What should I do? ANSWER: You should never compromise your or anyone else's safety. If someone is pressuring you to do so, you should report the issue.

ALCOHOL AND DRUG USE AND BEING FIT FOR WORK We do not compromise our ability to do our jobs or the safety of others through the use of intoxicants, including alcohol, drugs or medications whether they are legal or not. Given the nature of TC Energy's business, it is essential that all Personnel be fit to perform their jobs. The use of alcohol or drugs can impair your judgment and productivity and can lead to serious accidents and health and safety concerns – not only for yourself, but also for your coworkers and the public. TC Energy takes a zero-tolerance approach toward the use of alcohol, drugs and intoxication while working. You must always be fit for work while engaged in any TC Energy business. Inability to do so will result in serious consequences including being removed from our site(s) and subject to appropriate corrective action, up to and including termination of employment or contract. Ꝓ Alcohol and Drug Policy WHAT DOES BEING FIT FOR WORK MEAN? Fit for work means being able to safely and acceptably perform your assigned duties without any limitations due to the use or after-effects of any intoxicants. This can include legally-obtained medications (prescription and over the counter) which have the potential to change or adversely affect the way a person thinks, feels, or acts.

HUMAN RIGHTS Consistent with Our Commitment Statement, TC Energy does not tolerate human rights abuses. In our business activities, including engaging with Indigenous groups and stakeholders across Canada, the United States and Mexico, we are committed to respecting human rights. We will not be complicit with, nor engage in, any business activity that supports or facilitates abuse of human rights. As a participant in the United Nations (UN) Global Compact, TC Energy supports the Ten Principles of the UN Global Compact on human rights, labour, environment and anti-corruption.

PERSONAL RELATIONSHIPS Personnel who have a Personal Relationship within the Company must not be in a direct or indirect reporting relationship with each other. In particular, the Company prohibits all Intimate Relationships between individuals in a direct or indirect reporting relationship. If Personnel are not certain whether a Personal Relationship within the Company is permissible, they should immediately discuss their situation with their TC Energy leader HR Business Partners, or HR Governance. Failure to disclose a relationship that could place individuals in a conflict of interest or create the perception of a conflict of interest could be a breach of Company policy. QUESTION: I want to hire someone who I know has a family member already working for TC Energy. Is that allowed? ANSWER: Yes, it is acceptable to hire someone (Employee or CWC) who has family members already working for TC Energy provided that doing so does not result in the person directly or indirectly (through other leader(s)) reporting to their family member.

GIFTS, INVITATIONS AND ENTERTAINMENT Local customs with respect to providing gifts and other benefits can change depending on where we are doing business; however, these local customs must never compromise, or appear to compromise, our ability to act legally, ethically and objectively. While giving gifts can help to build and maintain strong business relationships, they can also cloud one's judgement or be seen to improperly influence decisions depending on the nature and context of the gift. We must always be prudent in offering gifts, entertainment or anything of value to anyone or any organization that is a competitor, or that TC Energy does or seeks to do business with, or that TC Energy requires consent or approval from (e.g., a government authority). Corruption in business and government prevents fair and open competition based on merit and it can have a negative impact for both the Company and the individual. To mitigate these negative impacts, we must all comply with TC Energy's Avoiding Bribery and Corruption Policy, Gift, Meals, Entertainment and Travel for Government Officials Standard, and Gifts and Entertainment Policy.

Accepting gifts, invitations and entertainment Accepting gifts or invitations from anyone or any organization can affect the way TC Energy is perceived and can run counter to our business objectives and values. We all have an obligation to conduct ourselves in a fair and impartial fashion in all business dealings with anyone or any organization. Careful consideration must be taken when offered a gift or an invitation to an event. Please see the Gifts and Entertainment Policy for more information. Ꝓ Avoiding Bribery and Corruption Policy Ꝓ Gifts and Entertainment Policy Ꝓ Gift, Meals, Entertainment and Travel for Government Officials Standard QUESTION: I have been invited by a shipper to attend the rodeo at the Calgary Stampede. Can I accept the invitation and attend the event? ANSWER: All Personnel must ensure they are acting in a manner which is fair and impartial and which does not create a real or perceived conflict of interest with those with whom we do business. As such, attendance at this event would only be acceptable if the criteria outlined in the Gifts and Entertainment Policy are met and, for Personnel below Vice-President (VP), prior approval is obtained from your VP or above. QUESTION: I sometimes receive items such as coffee mugs and pens from a company that I have a relationship with and which is a supplier to TC Energy. Am I able to accept these items? ANSWER: Personnel may accept occasional promotional gifts (such as pens, coffee mugs, calendars) as a customary business courtesy, provided that the gift does not exceed a value of CAD $150/ USD $150/ MXN $1000 per instance or total more than CAD $300/ USD $300/ MXN $2000 in aggregate for the calendar year from the same individual or organization. All dollar amounts for occasional promotional gifts are in local currency where they are being accepted. QUESTION: One of our existing auto leasing suppliers has invited me to attend their annual product roll-out, which will be held in Las Vegas. It is a big event that all customers are invited to. The supplier has offered to pay for all flights and accommodation, in addition to the meals that will be provided as part of the event. The supplier's contract is not currently up for renewal, and I am not the person responsible for making the decision whether to renew. Can I attend? ANSWER: Given the location of the event, the business benefit to TC Energy should be carefully considered and discussed with your leader. Additionally, since the value of the event is significant, the supplier's payment for flights and accommodation could create a perception of conflict and/or an obligation on the part of TC Energy. As a result, flights and accommodation should be paid for by TC Energy. You may accept the meals provided by the supplier as part of the event, provided they are not lavish in nature. Further, attendance at this event would only be acceptable if the criteria outlined in the Gifts and Entertainment Policy are met and, for Personnel below Vice-President (VP), prior approval is obtained from your VP or above.

ENGAGING GOVERNMENT OFFICIALS Engaging with Government Officials is an important part of TC Energy's business, and during those engagements, expenses for Government Officials may be incurred. You should never provide Government Officials with bribes, payments, kickbacks, gifts or anything else of value for the purpose of improperly influencing their actions or decisions in TC Energy's favour. These benefits can include entertainment, private parties, charitable contributions or employment opportunities. Even if there is no intent to influence, you should not provide a payment or benefit to any third party if it could appear to be improper. If a Government Official, Politically Exposed Person, Excluded Contractor, or any other person requests a bribe, kickback, or any other thing of value (including gifts, entertainment, travel, or other hospitality) that would be in violation of our policies, Personnel must refuse the request and make a record of the request as soon as possible. Mark the record as "confidential" and promptly provide it to your leader and Corporate Compliance so appropriate next steps can be determined. We are prohibited from offering, paying, promising or authorizing a compensation, payment or benefit to any Government Official, directly or indirectly, to secure any contract, concession or other improper advantage for TC Energy. Such action is prohibited even if the intent is not to influence a Government Official(s), as it could appear to be improper. Ꝓ Avoiding Bribery and Corruption Policy Ꝓ Gifts and Entertainment Policy Ꝓ Community Investment Standard Ꝓ Gift, Meals, Entertainment and Travel for Government Officials Standard With the exception of Mexico, many anti-corruption laws allow reasonable gifts or entertainment for Government Officials in limited circumstances. Only gifts, meals, and entertainment that are reasonable, do not influence business decisions and are not otherwise prohibited may be offered. All gifts, meals or entertainment must be provided in accordance with local laws and regulations, be appropriately recorded in TC Energy's books and records, and follow the appropriate approval processes and thresholds as set out in TC Energy's Gift, Meals, Entertainment and Travel for Government Officials Standard.

POLITICAL CONTRIBUTIONS AND LOBBYING TC Energy respects the political process and only makes political contributions and engages in lobbying activities that are legal and transparent. Legal requirements concerning political contributions and lobbying are aimed at preventing corruption in government and at ensuring proper functioning of the political system. These legal requirements can be complex and vary by jurisdiction. For example we are not allowed to make political donations at all in some jurisdictions. Also, there may be a legal requirement to be registered in some jurisdictions if you meet certain criteria. You must seek approval from the External Relations department before engaging in these activities on behalf of TC Energy. Ꝓ Political Contributions and Activities Policy QUESTION: I am very politically active. Is that allowed? ANSWER: You may participate in the political process on your personal time in accordance with your own political views and the laws and regulations governing this activity. In doing so, however, you may not use TC Energy's name, nor indicate that you represent TC Energy, unless you have been authorized to do so. Lobbying occurs when Personnel, acting on behalf of the Company, communicate with a Government Official usually in an attempt to influence a government decision, program, or policy. Personnel must report internally to External Relations all interactions and communications with Government Officials that involve any matter of interest to the Company using the appropriate channels outlined in the Political Contributions and Activities Policy.

INTERNATIONAL TRADE When engaging in international business and procuring products from the global marketplace, TC Energy complies with all applicable international trade laws, as well as all customs and taxation requirements. International trade laws prohibit or restrict trade with certain countries that are subject to embargoes or sanctions, as well as with certain individuals and organizations (e.g., entities that have ties to actual or suspected terrorists or drug traffickers). These laws also prohibit or restrict imports and exports of certain types of goods, information and technologies and often impose stringent reporting obligations. As part of contractual arrangements, mergers and acquisitions, debt covenants, and know-your-client requirements, TC Energy may need to make representations regarding compliance with sanctions and confirm that its Personnel are not sanctioned persons. A sanctioned person refers to an individual or entity that is sanctioned under the sanctions laws of, but not limited to, Canada, the U.S., Japan, the UK, or the EU. If at any time you become a sanctioned person, you are required to report this to Corporate Compliance. Ꝓ Customs and Trade Policy Prior to engaging in any transaction, you must ensure: • that it is legally permitted • that all applicable licensing requirements and reporting and customs obligations are met And consider: • the types and use of the goods, information or technology • the counterparty with which you are dealing • the country in which the counterparty is located Even if TC Energy does not have ownership of a product we have purchased when it crosses a border (e.g., because we take ownership or title on delivery), we may nevertheless be responsible for import and/or export compliance based on certain terms of the purchase contract. It is important to ensure the contract does not contain terms that result in TC Energy inadvertently taking on these obligations.

INSIDER TRADING We engage only in transactions that have a legitimate business purpose, and we do not interfere with the normal functioning of the markets in which we operate and transact. We also report transactions in accordance with all legal requirements. Through the course of your work with TC Energy, you may have access to non-public information regarding TC Energy, our customers, Contractors and other business partners. You must always maintain the confidentiality of any non-public information encountered through the course of business with TC Energy. To the extent non-public information that you are aware of could be material to a decision to buy or sell shares in TC Energy or another company: • You and your immediate family members must not trade TC Energy shares or other securities based on that information • You must not share material non-public information with another person, except as necessary in the course of business, as outlined in the Public Disclosure Policy. Ꝓ Trading Policy Ꝓ Public Disclosure Policy QUESTION: I own units of a mutual fund that invests in shares of one of our suppliers. Is that a problem? ANSWER: Your ownership of mutual fund units is likely not a problem. If your investment in the supplier is through a mutual fund, you would need to ensure that you do not own more than one per cent of the stock of the supplier; however, because of the indirect nature of the investment, it is also less of a concern than if you owned the shares directly. We conduct business in a way that promotes a fair, efficient and openly competitive operation of markets we participate in and which complies with market manipulation laws. Insider trading is a serious offence and can have significant reputational and legal impacts. For Securities and Insider trading inquiries contact Corporate Secretarial Filing Desk.

INTER-AFFILIATE INTERACTIONS As a transmission provider, TC Energy is subject to the Canadian Gas Pipelines Code of Conduct (Code) in Canada, the FERC Standards of Conduct (SOC) in the U.S., and the TC Energía Code of Conduct in Mexico (Inter-Affiliate Codes). These Inter-Affiliate Codes are intended to ensure that our non-regulated affiliates do not receive an unfair advantage over other customers, whether as a result of discriminatory treatment or the improper sharing of information, Personnel or resources. The Inter-Affiliate Codes also prohibit cross-subsidization at the expense of our transmission customers. In order to ensure compliance with the Inter-Affiliate Codes, you must observe the following rules in your day-to-day activities: All customers must be treated equally Regulated transmission providers cannot give undue preference to any customer, whether affiliated with a TC Energy entity or not. Independent functioning Regulated Personnel and affiliates must function independently of non-regulated Personnel and affiliates (e.g., they must function without coordination or the sharing of non-public Regulated Information\*). No conduit of information Regulated and shared Personnel must not share, or act as a conduit for the sharing of Regulated Information with non-regulated Personnel (e.g., by way of SharePoint links, Power Apps, Power Bi reports, data rooms, meetings etc.). Pay fair share Non-regulated affiliates must pay their fair share of any costs incurred by our regulated transmission providers, so as not to burden our transmission customers with costs our non-regulated entities benefit from. Reporting violations Any violations of the Inter-Affiliate Codes must be reported to the Inter-Affiliate Compliance department, since TC Energy may be legally required to either publicly post such information on its website or report it to our regulators. \*Regulated Information (which may not be shared with non-regulated Personnel or affiliates) includes commercial, financial, strategic, planning, operational and customer information of our transmission providers.

COMPETING FAIRLY A competitive marketplace in the energy and transmission services that TC Energy provides helps ensure fair prices and customer choice and, in turn, results in the industry as a whole providing more effective and better service. We believe in vigorous, fair competition and comply with all laws designed to protect the ability of companies to compete freely. You should never enter into agreements to: • Fix prices • Decrease capacity or volume available to customers • Allocate customers or markets among competitors • Boycott certain customers or Contractors You need to be very careful whenever you have contact with competitors (whether in trade association meetings, at conferences, through participation in benchmarking groups or in negotiating or otherwise dealing with actual or potential joint venture partners who are also TC Energy competitors) to avoid sharing competitively sensitive information. You must never enter into an agreement to reduce competition, or that is likely to have that effect. QUESTION: While at a trade association meeting recently, a few competitors I was sitting with at dinner started talking about their pricing. I knew it wasn't appropriate, so I didn't say anything. Did I do the right thing? ANSWER: While you were right not to participate in the discussion, when in such a situation, it's a good idea to take the further step of making clear to everyone that the discussion is inappropriate and that you will not participate. If the inappropriate discussion continues, you should excuse yourself from the situation. You should also document what happened and report the matter. This will help to protect you and TC Energy in case anyone ever points to the fact that you were part of a group in which an inappropriate discussion took place. Employees must seek approval from the External Relations department before making any corporate membership payments to trade associations.

ACCOUNTING, FINANCIAL REPORTING AND FRAUD PREVENTION TC Energy ensures that our accounting, financial records and reporting are fair, accurate, understandable and complete, and we do not falsify financial documents or records, or misstate or misrepresent the nature of costs or expenditures. You must ensure all transactions that you engage in, or that you approve, whether under a TC Energy contract or as an individual business expense, are true and reported accurately, completely and in compliance with all applicable accounting and legal requirements.

You must also never falsify any invoice, expenditure, time sheet, benefits claim or other document related to the Company, our stakeholders, Contractors or benefits providers.

PREVENTING MONEY LAUNDERING AND TERRORIST FINANCING We expect all our Personnel to be vigilant in ensuring the payments we make and the methods of payment we use are legitimate and legal. Legal requirements concerning money laundering and terrorist financing are in place to deter criminal and terrorist activities of those with whom we might do business. To ensure compliance with these legal requirements you must: • Exercise care before agreeing to do business with a third-party, including ensuring that they were reviewed as part of Supply Chain's qualification process • Ensure the third-party is legitimate and reputable • Recognize and report any suspicious payments or transactions Ignoring the signs that a transaction or payment initiated by a third party is not legitimate can result in TC Energy being found complicit in any illegal activity that may be associated with the transaction, even if the Company did not expressly authorize it or even know about it. Examples of suspicious payments or transactions include: • Any request by a third-party to have a payment deposited into a personal account rather than a business account • Transactions with entities other than those involved in the underlying contract or business deal • Payments or other transactions involving a country other than that in which the parties to the contract or business deal are located Payments of cash, unusual financing arrangements, fictitious invoices or other efforts by a third party to conceal the true purpose of a payment or transaction also raise concerns.

SOCIAL MEDIA AND COMMUNICATIONS WITH THE PUBLIC In the age of social media, it is easy to communicate information broadly and publicly. You need to be particularly aware of your obligations and our expectations when it comes to the disclosure of Company information and ensuring it is in accordance with legal and internal requirements. When sharing information on social media, keep the following requirements in mind: • Do not speak on behalf of or give the impression that you are speaking on behalf of TC Energy, unless you have been authorized to do so • Be clear that your comments represent your opinion and are not written on behalf of TC Energy • Use good judgement and ensure you do not post anything that reflects negatively on TC Energy or yourself, or that is discriminatory, offensive, or in poor taste • Be respectful of others, keeping in mind our Harassment-Free Workplace policies and make sure your comments cannot be seen in a negative light • Share only approved TC Energy content to ensure you are accurate and add value to the conversation • Do not disclose confidential, proprietary, or non-public information about TC Energy • Do not post pictures of TC Energy's facilities or operations unless you are authorized to do so and have received the required approvals • Never falsely represent yourself QUESTION: While scrolling through social media I saw anti LNG posts that my extended family were making. I wanted to comment on the post with some facts regarding the use of LNG in our everyday lives, but I didn't want to fuel the fire. Did I do the right thing? ANSWER: Yes, you did the right thing by not participating in the online discussion. Engaging with individuals who have opposing opinions or values to yourself or to the Company can increase hostility, and social media algorithms may also bring more attention to the conflict rather than the facts. . TC Energy recognizes that Personnel use social media for personal use. Personal use of social media must not interfere with your job. Personnel should be mindful that personal use of social media can also impact TC Energy, its business relationships, and reputation in the communities it serves.

PROTECTING CONFIDENTIAL INFORMATION We protect TC Energy's confidential information, and that of our customers, Contractors and other stakeholders, from improper disclosure and use.

All confidential information should be protected from unauthorized access. When disposing of confidential information, you should do so in a secure manner, which may include shredding of hard copies.

YOUR RESPONSIBILITY Personnel must follow all applicable provisions and the spirit and intent of this corporate governance document and support others in doing so. Personnel must promptly report any suspected or actual violation of this corporate governance document through available channels so that TC Energy can investigate and address it appropriately. Personnel who violate this corporate governance document or knowingly permit others under their supervision to violate it, may be subject to appropriate corrective action, up to and including termination of employment or contract, as applicable, in accordance with the Company's corporate governance documents, employment practices, contracts, collective bargaining agreements and processes. INTERPRETATION AND ADMINISTRATION The Company has sole discretion to interpret, administer and apply this corporate governance document and to change it at any time to address new or changed legal requirements or business circumstances. NON-RETALIATION TC Energy supports and encourages Employees and Contractors to report suspected violations of corporate governance documents, applicable laws, regulations, and authorizations, as well as hazards, potential hazards, incidents involving health and safety or the environment, and near hits.

ASKING QUESTIONS AND REPORTING CONCERNS You are required to report in a timely manner any actual or potential non-compliance with COBE, any other TC Energy policies, or any legal obligation, as it applies to you or the Company, so it can be appropriately investigated and addressed. You can do so with confidence that your confidentiality and identity will be protected to the greatest extent possible and that retaliation for good faith reporting is prohibited. ETHICS HELP LINE Although TC Energy has various reporting resources available for Personnel to report a concern or to seek guidance, there may be times when you are not comfortable raising concerns through those resources. TC Energy's Ethics Help Line is operated by an independent third-party service provider and reporting through the Ethics Help Line is confidential and may be done anonymously. ETHICS HELP LINE Canada / U.S.: 1-888-920-2042 Mexico: 800-283-2783 (if calling from a cell phone) 0-800-283-2783 (if calling from a land line) TCEnergy.com/about/governance/code-of-business-ethics All calls to the Ethics Help Line are free of charge, and can be made in English, French, or Spanish 24 hours a day, seven days a week, 365 days a year. You may use the Ethics Help Line either to report any actual or suspected issues or to ask questions on topics such as: • Accounting irregularities • Alcohol and drug abuse • Conflicts of interest • Employee concerns • Employment practices • Engineering concerns • Environment concerns • Equitable treatment • Harassment • Human rights • Safety • Theft and fraud • Workplace violence • Other improprieties If the issue raises an immediate threat to safety or security, you should contact Corporate Security, local police or other emergency services as appropriate. All reports are taken seriously Regardless of the means used to report, your report will be taken seriously and it will be investigated and addressed appropriately. If you are reporting through the Ethics Help Line, please make note of your key code for your case file since the investigator may contact you through your case file for further information or clarification prior to initiating an investigation. Participation in investigations and audits Personnel, including directors and officers are required to participate in investigations and audits if, and as, requested. QUESTION: I suspect one of my colleagues has violated part of COBE, but I'm not sure my suspicions are correct. I'm concerned I'll be labeled a tattle-tale (or worse) if I report it. What should I do? ANSWER: If you suspect misconduct, you should report it in a timely manner so it can be investigated. If it turns out not to be an issue, there will be no harm done. However, violations of the law or COBE that are not reported, cannot be addressed, and that can seriously undermine the Company. If that happens, we all suffer. If you report the issue, your confidentiality and identity will be protected and if any retaliation is found to occur, it will be taken very seriously.
