NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(Unaudited)

Note 1: Basis of Presentation

Boardwalk Pipeline Partners, LP (the Company) is a Delaware limited partnership formed in 2005 to own and operate the business conducted by its primary subsidiary Boardwalk Pipelines, LP (Boardwalk Pipelines) and its operating subsidiaries, which consists of integrated pipeline and storage systems for natural gas and natural gas liquids, olefins and other hydrocarbons (herein referred to together as NGLs). As of March 31, 2025, Boardwalk Pipelines Holding Corp. (BPHC), a wholly owned subsidiary of Loews Corporation (Loews), owned directly or indirectly, 100% of the Company's capital.

The accompanying unaudited condensed consolidated financial statements of the Company have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission. Certain information and footnote disclosures normally included in annual financial statements prepared in accordance with accounting principles generally accepted in the United States of America (U.S.) (GAAP) have been condensed or omitted pursuant to such rules and regulations. In the opinion of management, the accompanying unaudited condensed consolidated financial statements reflect all adjustments (consisting of only normal recurring accruals) necessary to present fairly the Company's financial position as of March 31, 2025, and December 31, 2024, and its results of operations, comprehensive income and changes in cash flow and partners' capital for the three months ended March 31, 2025 and 2024, in each case in accordance with GAAP. Reference is made to the Notes to the Consolidated Financial Statements in the Company's Annual Report on Form 10-K for the year ended December 31, 2024 (2024 Annual Report on Form 10-K), which should be read in conjunction with these unaudited condensed consolidated financial statements. The accounting policies described in Note 2 of Part II, Item 8. of the Company's 2024 Annual Report on Form 10-K are the same policies that were used in preparing the accompanying unaudited condensed consolidated financial statements. Results of operations for interim periods may not necessarily be indicative of results for the full year.

The Company recently reorganized its legal entity structure which impacted its reporting units for purposes of goodwill. Goodwill was reallocated based on the relative fair value approach, resulting in $4.5 million of goodwill being transferred to a different reporting unit. The Company now has three reporting units for goodwill testing. This reorganization was considered a triggering event for purposes of interim goodwill impairment testing. As a result, quantitative goodwill impairment tests were performed during the first quarter 2025 on the impacted reporting units and the results of the goodwill impairment tests indicated that the fair value of the Company's impacted reporting units exceeded their carrying amounts.

In the fourth quarter 2024, the Company began reporting its financial results in two reportable segments, Natural Gas and Natural Gas Liquids, whereas it previously reported under a single operating and reportable segment. Certain information for 2024 in Notes 2 and 10 has been recast or presented under the Company’s reportable segment presentation.

Note 2: Revenues

The Company contracts directly with end-use customers, including electric power generators, local distribution companies, industrial users and exporters of liquefied natural gas. The Company also contracts with other customers, including producers and marketers of natural gas and interstate and intrastate pipelines, who, in turn, provide transportation and storage services for end-users. The following tables present the Company's revenues disaggregated by type of service by segment (in millions):


	For the Three Months Ended March 31, 2025
	Natural Gas		Natural Gas Liquids		Eliminations		Total
Revenues from Contracts with Customers
Firm Service (1)	$	401.6	$	152.8	$	(8.3)	$	546.1
Interruptible Service	13.0		—		—		13.0
Other revenues	3.2		46.2		—		49.4
Total Revenues from Contracts with Customers	417.8		199.0		(8.3)		608.5
Other operating revenues (2)	5.9		8.9		(4.7)		10.1
Total Operating Revenues	$	423.7	$	207.9	$	(13.0)	$	618.6

(1)Revenues earned from contracts with minimum volume commitments (MVCs) are included in firm service given the stand-ready nature of the performance obligation and the guaranteed nature of the fees over the contract term.

(2)Other operating revenues include certain revenues earned from operating leases, pipeline management fees, intrasegment licensing fees and other activities that are not considered central and ongoing major business operations of the Company and do not represent revenues earned from contracts with customers.


	For the Three Months Ended March 31, 2024
	Natural Gas		Natural Gas Liquids		Eliminations		Total
Revenues from Contracts with Customers
Firm Service (1)	$	362.1	$	85.6	$	(7.5)	$	440.2

Other revenues	6.3		42.3		—		48.6
Total Revenues from Contracts with Customers	380.3		127.9		(7.5)		500.7
Other operating revenues (2)	5.4		9.3		(4.9)		9.8
Total Operating Revenues	$	385.7	$	137.2	$	(12.4)	$	510.5

(1)Revenues earned from contracts with MVCs are included in firm service given the stand-ready nature of the performance obligation and the guaranteed nature of the fees over the contract term.

Contract Balances

As of March 31, 2025, and December 31, 2024, the Company had receivables recorded in Trade Receivables, net from contracts with customers of $216.6 million and $210.7 million, contract assets recorded in Other Assets from contracts with a customer of $12.7 million and $11.9 million, and contract liabilities recorded in Other Current Liabilities (current portion) and Other Liabilities (noncurrent portion) from contracts with customers of $19.4 million and $17.9 million.

Performance Obligations

The following table includes estimated operating revenues expected to be recognized in the future related to agreements that contain performance obligations that were unsatisfied as of March 31, 2025. The amounts presented primarily consist of fixed fees or MVCs which are typically recognized over time as the performance obligation is satisfied, in accordance with firm service contracts, or at a point in time as guaranteed minimum fees associated with the performance obligation are satisfied under certain ethane supply contracts. For the Company's customers that are charged maximum tariff rates related to its Federal Energy Regulatory Commission regulated operating subsidiaries, the amounts below reflect the current tariff rate for such services for the term of the agreements; however, the tariff rates may be subject to future adjustment. The Company has elected to exclude the following from the table: (a) unsatisfied performance obligations from usage fees associated with its firm services because of the variable nature of such services; (b) unsatisfied performance obligations from the ethane commodity indexed portion of ethane supply contracts because of the variable nature of ethane prices, and (c) consideration in contracts that is recognized in revenue as invoiced, such as for interruptible services. The estimated revenues reflected in the table include estimated revenues that are anticipated under executed precedent transportation agreements for growth projects that are subject to regulatory approvals.


	In millions
	2025 (1)		2026		Thereafter		Total

Estimated revenues from contracts with customers from unsatisfied performance obligations as of March 31, 2025 (2)	$	1,146.5	$	1,409.0	$	11,579.0	$	14,134.5
Operating revenues which are fixed and determinable (operating leases)	21.0		27.5		136.0		184.5
Total projected operating revenues under committed firm agreements as of March 31, 2025 (3)	$	1,167.5	$	1,436.5	$	11,715.0	$	14,319.0

(1)The 2025 period is for the remaining nine months ending December 31, 2025. For the three months ended March 31, 2025, the Company recognized $426.2 million of fixed fee revenues for the fulfillment of performance obligations.

(2)In March 2024, the Company executed a 108-year firm storage agreement with a customer. The estimated annual revenue from this contract is $3.1 million, with $328.5 million of unsatisfied performance obligations included in the “Thereafter” column. Per the tariff provisions, this customer was required to provide 90 days of collateral and the Company can suspend services due to non-payment.

(3)The estimated revenues from contracts with customers from unsatisfied performance obligations as of March 31, 2025, that are anticipated under executed precedent transportation agreements associated with the Company's growth projects are $4.0 billion.

Note 3: Gas and Liquids Stored Underground and Gas and NGLs Receivables and Payables

The operating subsidiaries of the Company provide storage services whereby they store natural gas or NGLs on behalf of customers and also periodically hold customer gas under parking and lending (PAL) services. Since the customers retain title to the gas or NGLs held by the Company in providing these services, the Company does not record the related gas or NGLs on its Condensed Consolidated Balance Sheets.

The operating subsidiaries of the Company also periodically lend gas to customers under PAL and certain firm services, and lend ethylene to customers under exchange agreements, and gas or NGLs may be owed to the Company's operating subsidiaries as a result of transportation imbalances. As of March 31, 2025, the amount of gas owed to the Company's operating subsidiaries due to gas imbalances and gas loaned under PAL and certain firm service agreements was approximately 26.7 trillion British thermal units (TBtu). Assuming an average market price during March 2025 of $3.80 per million British thermal unit (MMBtu), the market value of that gas was approximately $101.5 million. As of March 31, 2025, the amount of ethylene owed to the Company’s operating subsidiaries from ethylene loaned under exchange agreements was approximately 33.0 million pounds. Assuming an average market price during March 2025 of $0.23 per pound, the market value of that ethylene was approximately $7.6 million. As of March 31, 2025, there were no outstanding NGLs imbalances owed to the Company's operating subsidiaries. As of December 31, 2024, the amount of gas owed to the Company's operating subsidiaries due to gas imbalances and gas loaned under PAL and certain firm service agreements was approximately 9.8 TBtu. Assuming an average market price during December 2024 of $2.98 per MMBtu, the market value of that gas was approximately $29.2 million. As of December 31, 2024, the amount of NGLs owed to the Company's operating subsidiaries due to imbalances was less than 0.1 million barrels, which had a market value of approximately $0.3 million. As of December 31, 2024, there were no amounts of ethylene owed to the Company's operating subsidiaries under exchange agreements.

Note 4: Fair Value Measurements and Investments

Financial Assets and Liabilities

The methods and assumptions used in estimating the fair value amounts included in the disclosures for financial assets and liabilities are consistent with those disclosed in the Company's 2024 Annual Report on Form 10-K.

The carrying amounts and estimated fair values of the Company's financial assets and liabilities which were not recorded at fair value on the Condensed Consolidated Balance Sheets as of March 31, 2025, and December 31, 2024, were as follows (in millions):


As of March 31, 2025				Estimated Fair Value
Financial Assets	Carrying Amount			Level 1		Level 2		Level 3		Total
Cash and cash equivalents	$	235.2		$	235.2	$	—	$	—	$	235.2
Financial Liabilities
Long-term debt	$	3,237.2	(1)	$	—	$	3,160.9	$	—	$	3,160.9

(1)The carrying amount of long-term debt excluded a $2.5 million long-term finance lease obligation and $4.6 million of unamortized debt issuance costs.


As of December 31, 2024				Estimated Fair Value
Financial Assets	Carrying Amount			Level 1		Level 2		Level 3		Total
Cash and cash equivalents	$	117.9		$	117.9	$	—	$	—	$	117.9
Financial Liabilities
Long-term debt	$	3,236.5	(1)	$	—	$	3,129.7	$	—	$	3,129.7

(1)The carrying amount of long-term debt excluded a $2.7 million long-term finance lease obligation and $4.8 million of unamortized debt issuance costs.

Note 5: Commitments and Contingencies

Legal Proceedings and Settlements

The Company and its subsidiaries are parties to various legal actions arising in the normal course of business. Management believes the disposition of these outstanding legal actions, including the legal actions identified below, will not have a material impact on the Company's financial condition, results of operations or cash flows.

Mishal and Berger Litigation

On May 25, 2018, plaintiffs Tsemach Mishal and Paul Berger (on behalf of themselves and the purported class, Plaintiffs) initiated a purported class action in the Court of Chancery of the State of Delaware (the Trial Court) against the following defendants: the Company, Boardwalk GP, LP (Boardwalk GP), Boardwalk GP, LLC and BPHC (together, Defendants), regarding the potential exercise by Boardwalk GP of its right to purchase the issued and outstanding common units of the Company not already owned by Boardwalk GP or its affiliates (Purchase Right).

On June 25, 2018, Plaintiffs and Defendants entered into a Stipulation and Agreement of Compromise and Settlement, subject to the approval of the Trial Court (the Proposed Settlement). Under the terms of the Proposed Settlement, the lawsuit would be dismissed, and related claims against the Defendants would be released by the Plaintiffs, if BPHC, the sole member of the general partner of Boardwalk GP, elected to cause Boardwalk GP to exercise its Purchase Right for a cash purchase price, as determined by the Company's Third Amended and Restated Agreement of Limited Partnership, as amended (the Limited Partnership Agreement), and gave notice of such election as provided in the Limited Partnership Agreement within a period specified by the Proposed Settlement. On June 29, 2018, Boardwalk GP elected to exercise the Purchase Right and gave notice

within the period specified by the Proposed Settlement. On July 18, 2018, Boardwalk GP completed the purchase of the Company's common units pursuant to the Purchase Right.

On September 28, 2018, the Trial Court denied approval of the Proposed Settlement. On February 11, 2019, a substitute verified class action complaint was filed in this proceeding, which, among other things, added Loews as a Defendant. The Defendants filed a motion to dismiss, which was heard by the Trial Court in July 2019. In October 2019, the Trial Court ruled on the motion and granted a partial dismissal, with certain aspects of the case proceeding to trial. A trial was held the week of February 22, 2021, and post-trial oral arguments were held on July 14, 2021.

On November 12, 2021, the Trial Court issued a ruling in the case. The Trial Court held that Boardwalk GP breached the Limited Partnership Agreement and found that Boardwalk GP was liable to the Plaintiffs for approximately $690.0 million in damages, plus pre-judgment interest (approximately $166.0 million), post-judgment interest and attorneys' fees. The Trial Court's ruling and damages award was against Boardwalk GP, and not the Company or its subsidiaries.

The Defendants believed that the Trial Court ruling included factual and legal errors. Therefore, on January 3, 2022, the Defendants appealed the Trial Court's ruling to the Supreme Court of the State of Delaware (the Supreme Court). On January 17, 2022, the Plaintiffs filed a cross-appeal to the Supreme Court contesting the calculation of damages by the Trial Court. Oral arguments were held on September 14, 2022, and on December 19, 2022, the Supreme Court reversed the Trial Court's ruling and remanded the case to the Trial Court for further proceedings related to claims not decided by the Trial Court's ruling. Briefing by the parties at the Trial Court on the remanded issues was completed in September 2023. A hearing on the remanded issues was held at the Trial Court in April 2024. In September 2024, the Trial Court ruled in favor of the Defendants on all of the remanded issues.

On October 21, 2024, the Plaintiffs appealed the Trial Court's ruling on the remanded issues to the Supreme Court. Briefing on this appeal was completed in March 2025 and a hearing on this appeal has been scheduled to occur in June 2025.

City of New Orleans Litigation

Gulf South Pipeline Company, LLC (Gulf South), along with several other energy companies operating in Southern Louisiana, has been named as a defendant in a petition for damages and injunctive relief in state district court for Orleans Parish, Louisiana, (Case No. 19-3466) by the City of New Orleans. The case was filed on March 29, 2019. The lawsuit claims include, among other things, negligence, strict liability, nuisance and breach of contract, alleging that the defendants' drilling, dredging, pipeline and industrial operations since the 1930s have caused increased storm surge risk, increased flood protection costs and unspecified damages to the City of New Orleans. In October 2020, this case was stayed pending the outcome of a consolidated appeal to the Fifth Circuit Court of Appeals in a similar case. On August 5, 2021, the Fifth Circuit Court of Appeals ruled in favor of the oil-and-gas defendants in that consolidated appeal, finding that the two cases being appealed should be re-examined in federal district court since they involve operations that were federally overseen at the time. The ruling reverses a previous decision that allowed the cases to be heard in state court, which the plaintiffs had sought. As a result of the Fifth Circuit Court of Appeals' decision, it is anticipated that this case will be reviewed in federal district court to determine whether the case should be heard in that court. Discovery has been initiated.

Gulf South has been named as a defendant in another suit in the State of Louisiana that is similar in nature to the City of New Orleans Litigation discussed above. This case was filed in the Louisiana state courts and discovery is ongoing.

Note 10: Reportable Segments

The Company has two reportable segments, Natural Gas and Natural Gas Liquids, which comprise 100% of the Company’s operating revenues. The Chief Operating Decision Maker (CODM) uses earnings before interest, income taxes, depreciation and amortization (EBITDA) to assess each of the Company’s segments performance and to determine how to allocate resources. The CODM uses this measure, together with other non-financial measures, when assessing performance of the Company and establishing management’s compensation. The Company provides segment expenses to its CODM on the same basis as the expenses are provided in the Company’s income statement and used to calculate EBITDA. Refer to the Company's 2024 Annual Report on Form 10-K for further information.

Item 2. Management's Discussion and Analysis of Financial Condition and Results of Operations

The following discussion and analysis of financial condition and results of operations should be read in conjunction with our accompanying interim condensed consolidated financial statements and related notes, included elsewhere in this report, and prepared in accordance with accounting principles generally accepted in the United States of America (U.S.) (GAAP), and our consolidated financial statements, related notes, Management's Discussion and Analysis of Financial Condition and Results of Operations and Risk Factors included in our Annual Report on Form 10-K for the year ended December 31, 2024 (2024 Annual Report on Form 10-K).

We operate in the midstream portion of the natural gas and natural gas liquids, olefins and other hydrocarbons industry, providing transportation and storage for those commodities. We also provide ethane supply and transportation services for industrial customers in Louisiana and Texas.

Consolidated Results of Operations

Note 2 in Part II, Item 8. of our 2024 Annual Report on Form 10-K contains a summary of our revenue contracts and the related revenue recognition policies. A significant portion of our revenues are fee-based, being derived from capacity reservation charges under firm agreements with customers, which do not vary significantly period to period, but are impacted by longer-term trends in our business, such as changes in pricing on contract renewals and other factors as discussed in our 2024 Annual Report on Form 10-K. The pricing contained in the purchase and sales agreements associated with our ethane supply services is generally based on the same ethane commodity index, plus a fixed delivery fee. As a result, except for possible timing differences that may occur when volumes are purchased in one month and sold in another month, our ethane supply services, like our other businesses, have little to no direct commodity price exposure. Our operating costs and expenses do not vary significantly based upon the volume of products transported, with the exception of costs recorded in Costs associated with service revenues. Our operations and maintenance expenses are impacted by our compliance with the requirements of, among other regulations, the Pipeline and Hazardous Materials Safety Administration Mega Rule and our efforts to monitor, control and reduce emissions, as further discussed in our 2024 Annual Report on Form 10-K.

We use earnings before interest, income taxes, depreciation and amortization (EBITDA), a measure not included in U.S. GAAP, as a financial measure to assess our operating and financial performance and return on invested capital. We believe that some investors may find this measure useful in evaluating our performance as EBITDA is a commonly used metric within the midstream industry.

The following table presents a reconciliation of net income to EBITDA (in millions):


	For the Three Months Ended March 31,
	2025		2024
Net income	$	206.6	$	164.8
Income taxes	0.5		0.4
Depreciation and amortization	105.5		105.5
Interest expense	39.5		43.3
Interest income	(1.0)		(3.7)
EBITDA	$	351.1	$	310.3

For the Three Months Ended March 31, 2025 and 2024

Our net income for the three months ended March 31, 2025, increased $41.8 million, or 25%, to $206.6 million compared to $164.8 million for the three months ended March 31, 2024. Our EBITDA increased $40.8 million, or 13%, to $351.1 million for the same period. Our net income and EBITDA increased primarily due to the factors discussed below.

Operating revenues for the three months ended March 31, 2025, increased $108.1 million, or 21%, to $618.6 million compared to $510.5 million for the three months ended March 31, 2024. Our transportation revenues increased $33.7 million, primarily due to re-contracting at higher rates and recently completed growth projects; our storage, parking and lending (PAL) revenues increased $6.6 million due to favorable market conditions which allowed for contracting at higher rates; and our product sales revenues increased $68.0 million primarily from higher volumes from the sale of ethane due to a customer outage in 2024, which impacted 2024 volumes.

Operating costs and expenses for the three months ended March 31, 2025, increased $65.5 million, or 21%, to $374.2 million compared to $308.7 million for the three months ended March 31, 2024, primarily from higher product costs associated with increased ethane product sales.

Our interest income and expense for the three months ended March 31, 2025, as compared to the same period in the prior year, were impacted by the following items:

•decreased interest expense of $3.8 million due to lower average outstanding long-term debt; and

•decreased interest income of $2.7 million due to income earned from cash invested in short-term investments in 2024 from the pre-financing of a December 2024 debt maturity.

Segment Results

In the fourth quarter 2024, we began reporting our operations under two business segments: Natural Gas and Natural Gas Liquids. Management uses Segment EBITDA, which is contained in Note 10 in Part I, Item 1. of this Quarterly Report on Form 10-Q, as a basis to assess segment financial performance and allocate resources.

The following table provides our Total Segment EBITDA and a reconciliation to EBITDA (in millions):


	For the Three Months Ended March 31,
	2025		2024
Natural Gas	$	290.6	$	264.3
Natural Gas Liquids	60.5		46.0
Total Segment EBITDA	$	351.1	$	310.3

For the Three Months Ended March 31, 2025 and 2024

Natural Gas Segment

The Natural Gas segment's operating revenues for the three months ended March 31, 2025, increased $38.0 million or 9.9%, to $423.7 million, compared to $385.7 million for the three months ended March 31, 2024. Segment operating costs increased $11.7 million for the three months ended March 31, 2025, or 9.6%, to $133.1 million, compared to $121.4 million for the three months ended March 31, 2024. EBITDA increased by $26.3 million to $290.6 million for the same period.

EBITDA for the three months ended March 31, 2025, as compared to the same period in the prior year, was primarily impacted by the following items:

•increased transportation revenues of $32.6 million primarily due to re-contracting at higher rates, recently completed growth projects and higher utilization-based revenue;

•increased storage and PAL revenues of $7.8 million due to favorable market conditions which allowed for re-contracting at higher rates;

•decreased natural gas product sales of $3.6 million; and

•lower gains from contract settlements of $6.7 million.

Natural Gas Liquids Segment

The Natural Gas Liquids segment's operating revenues for the three months ended March 31, 2025, increased $70.7 million, or 51.5%, to $207.9 million compared to $137.2 million for the three months ended March 31, 2024. Segment operating costs increased $56.2 million for the three months ended March 31, 2025, or 61.6%, to $147.4 million, compared to

$91.2 million for the three months ended March 31, 2024. EBITDA increased by $14.5 million to $60.5 million for the same period.

EBITDA for the three months ended March 31, 2025, as compared to the same period in the prior year, was primarily impacted by the following items:

•increased propane and ethylene product sales of $7.6 million due to opportunistic market conditions;

•increased ethane product sales of $64.0 million primarily from higher volumes in 2025 due to a customer outage in 2024, which impacted 2024 volumes; and

•increased product costs associated with increased ethane product sales of $58.5 million.

Liquidity and Capital Resources

In the first three months of 2025, we paid total distributions of $75.0 million to Boardwalk GP, LP and Boardwalk Pipelines Holding Corp. We anticipate that our existing capital resources, including our cash and cash equivalents, revolving credit facility and our cash flows from operating activities, will be adequate to fund our operations and capital expenditures for 2025. As of March 31, 2025, we also have an effective shelf registration statement on file with the Securities and Exchange Commission (SEC) under which we may publicly issue up to $900.0 million of debt securities, warrants or rights from time to time.

Guarantee of Securities of Subsidiaries

Our debt is primarily issued at Boardwalk Pipelines, LP (Boardwalk Pipelines), our wholly owned subsidiary, although we have historically also issued debt at our operating subsidiaries. As of March 31, 2025, all of the outstanding notes issued by Boardwalk Pipelines (Subsidiary Issuer) and the full amount of the revolving credit facility were guaranteed by us (Parent Guarantor). The purpose of the guarantees is to help simplify our reporting and capital structure.

We guarantee amounts borrowed under the revolving credit facility, but any amounts borrowed are not subject to the reporting requirements of Rule 13-01 of Regulation S-X (Rule 13-01). As of March 31, 2025, there were no outstanding borrowings under the revolving credit facility. The following table identifies our principal amounts outstanding for the debt that is subject to the disclosure rules of Rule 13-01 (in millions):


	As of March 31, 2025
Principal amounts guaranteed by Boardwalk Pipeline Partners and subject to Rule 13-01 (1)	$	3,150.0
Principal amounts not guaranteed (2)	100.0
Other (3)	(14.9)
Total debt and finance lease obligation	$	3,235.1

(1)This represents principal amounts of all outstanding debt at Boardwalk Pipelines subject to the disclosure rules of Rule 13-01 (the Guaranteed Notes).

(2)This represents principal amounts of outstanding debt at Texas Gas Transmission, LLC.

(3)This represents amounts related to a finance lease and unamortized debt discount and issuance costs.

The Guaranteed Notes are fully and unconditionally guaranteed by the Parent Guarantor on a senior unsecured basis. The guarantees of the Guaranteed Notes rank equally with all of our existing and future senior debt, including our guarantee of indebtedness under our revolving credit facility. The guarantees will be effectively subordinated in right of payment to all of our future secured debt to the extent of the value of the assets securing such debt. There are no restrictions on the Subsidiary Issuer's ability to pay dividends or make loans to the Parent Guarantor. The guaranteed obligations will be terminated with respect to any series of notes if that series has been discharged or defeased.

Our operating assets, operating liabilities, operating revenues, expenses and other comprehensive income either exist at or are generated by our operating subsidiaries. The Parent Guarantor and the Subsidiary Issuer have no material assets, liabilities or operations independent of their respective financing activities, which includes the Guaranteed Notes and interest

expense of $37.9 million for the three months ended March 31, 2025, and includes advances to and from each other, and their investments in the operating subsidiaries. For these reasons, we meet the criteria in Rule 13-01 to omit the summarized financial information from our disclosures.

Capital Expenditures

Maintenance capital expenditures for the three months ended March 31, 2025 and 2024, were $35.8 million and $38.4 million. Growth capital expenditures for the three months ended March 31, 2025 and 2024, were $15.8 million and $58.9 million.

Contractual Obligations

Our future principal payments associated with our outstanding debt obligations were $3.3 billion as of March 31, 2025, and December 31, 2024. Refer to Note 6 in Part I, Item 1. of this Quarterly Report on Form 10-Q and Note 12 in Part II, Item 8. of our 2024 Annual Report on Form 10-K for more information on our financing activities and debt obligations.

Critical Accounting Estimates and Policies

Certain amounts included in or affecting our unaudited condensed consolidated financial statements and related disclosures must be estimated, requiring us to make certain judgments and assumptions with respect to values or conditions that cannot be known with certainty at the time the financial statements are prepared. These estimates and assumptions affect the reported amounts of assets, liabilities, revenues and expenses, and related disclosures of contingent assets and liabilities in our condensed consolidated financial statements. We review our estimates and assumptions on an ongoing basis, utilizing historical experience, consultation with third parties and other methods we consider reasonable. Nevertheless, actual results may differ materially from our estimates. Any effects on our business, financial position or results of operations resulting from revisions to these estimates are recorded in the periods in which the facts that give rise to the revisions become known.

During 2025, there have been no significant changes to our critical accounting policies, judgments or estimates from those disclosed in our 2024 Annual Report on Form 10-K.

Forward-Looking Statements

Certain statements contained in this Quarterly Report on Form 10-Q, as well as some statements in our other filings with the SEC and periodic press releases and some statements made by our officials, and us and our subsidiaries during presentations about us, are "forward-looking." Forward-looking statements include, without limitation, any statement that may project, indicate or imply future results, events, performance, intentions or achievements, and may contain the words "expect," "intend," "plan," "anticipate," "estimate," "believe," "will likely result" and similar expressions. In addition, any statement concerning future financial performance (including future revenues, earnings or growth rates), ongoing business strategies or prospects and possible actions by us or our subsidiaries, are also forward-looking statements.

Forward-looking statements are based on current expectations and projections about future events and their potential impact on us. While management believes that these forward-looking statements are reasonable as and when made, there is no assurance that future events affecting us will be those that we anticipate. All forward-looking statements are inherently subject to a variety of risks and uncertainties, many of which are beyond our control, which could cause actual results to differ materially from those anticipated or projected. These include, among others, the impacts of legislative and regulatory initiatives, or the implementation thereof, the impacts of climate change, environmental, social and governance matters and pipeline safety requirements and initiatives, the costs of maintaining and ensuring the integrity and reliability of our pipeline systems, our ability to complete growth projects that we have commenced or will commence, the risk of a failure in computer systems or cybersecurity attack, successful negotiation, consummation and completion of contemplated transactions, projects and agreements, risks and uncertainties related to the impacts of volatility in energy prices and our exposure to credit risk relating to default or bankruptcy by our customers. Developments in any of these areas could cause our results to differ materially from results that have been or may be anticipated or projected. Forward-looking statements speak only as of the date they are made and we expressly disclaim any obligation or undertaking to update these statements to reflect any change in our expectations or beliefs or any change in events, conditions or circumstances on which any forward-looking statement is based.

Refer to Part I, Item 1A. of our 2024 Annual Report on Form 10-K for additional risks and uncertainties regarding our forward-looking statements.

Item 4. Controls and Procedures

Disclosure Controls and Procedures

As required by Rule 13a-15(b) of the Securities Exchange Act of 1934 (Exchange Act), we have evaluated, under the supervision and with the participation of our management, including our principal executive officer and principal financial officer, the effectiveness of the design and operation of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act) as of the end of the period covered by this Quarterly Report on Form 10-Q. Our disclosure controls and procedures are designed to allow timely decisions regarding required disclosure and to provide reasonable assurance that the information required to be disclosed by us in reports that we file under the Exchange Act is accumulated and communicated to our management, including our principal executive officer and principal financial officer, as appropriate, and is recorded, processed, summarized and reported within the time periods specified in the rules and forms of the SEC. Based upon the evaluation, our principal executive officer and principal financial officer have concluded that our disclosure controls and procedures were effective as of March 31, 2025, at the reasonable assurance level.

Changes in Internal Control over Financial Reporting

There were no changes in our internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) that occurred during the quarter ended March 31, 2025, that have materially affected or that are reasonably likely to materially affect our internal control over financial reporting.
