NOTE 1 — DESCRIPTION OF THE BUSINESS AND BASIS OF PRESENTATION

Description of the Business

DT Midstream is an owner, operator, and developer of an integrated portfolio of natural gas midstream assets. We provide multiple, integrated natural gas services to customers through two segments: (i) Pipeline, which includes interstate pipelines, intrastate pipelines, storage systems, gathering lateral pipelines including related treatment plants and compression and surface facilities, and (ii) Gathering, which includes gathering systems, related treatment plants, and compression and surface facilities. Our Pipeline segment also includes joint venture interests in equity method investees which own and operate interstate pipelines that connect to our wholly owned assets.

Our core assets strategically connect key demand centers in the Midwestern U.S., Eastern Canada and Northeastern U.S. regions to the premium production areas of the Marcellus/Utica natural gas formation in the Appalachian Basin, and connect key demand centers and LNG export terminals in the Gulf Coast region to premium production areas of the Haynesville natural gas formation.

Basis of Presentation

The DT Midstream Consolidated Financial Statements and Notes to Consolidated Financial Statements are prepared under GAAP. These accounting principles require management to use estimates and assumptions that impact reported amounts of assets, liabilities, revenues and expenses, and the disclosure of contingent assets and liabilities. Actual results may differ from our estimates. We believe the assumptions underlying these financial statements are reasonable.

In our opinion, the accompanying unaudited Consolidated Financial Statements include all adjustments, consisting of normal recurring adjustments, necessary to present a fair statement of our financial position as of June 30, 2024, results of operations for the three and six months ended June 30, 2024 and 2023, statement of changes in stockholders' equity for the three and six months ended June 30, 2024 and 2023, and cash flows for the six months ended June 30, 2024 and 2023. The balance sheet as of December 31, 2023 was derived from audited annual financial statements but does not include all disclosures required by GAAP. Financial results for this interim period are not necessarily indicative of results that may be expected for any other interim period or for the year ending December 31, 2024. The Consolidated Financial Statements should be read in conjunction with DT Midstream's Consolidated Financial Statements and Notes to Consolidated Financial Statements included in DT Midstream's 2023 Annual Report on Form 10-K.

Principles of Consolidation

We consolidate all majority-owned subsidiaries and investments in entities in which we have a controlling influence. Non-controlled investments are accounted for using the equity method of accounting when we are able to significantly influence the operating policies of the investee. When we do not influence the operating policies of an investee, the equity investment is measured at fair value, if readily determinable, or if not readily determinable, at cost less impairment, if applicable. We eliminate all intercompany balances and transactions.

We evaluate whether an entity is a VIE whenever reconsideration events occur. We consolidate VIEs for which we are the primary beneficiary. When assessing the determination of the primary beneficiary, we consider all relevant facts and circumstances, including: the power, through voting or similar rights, to direct the activities of the VIE that most significantly impact the VIE's economic performance and the obligation to absorb the expected losses and/or the right to receive the expected returns of the VIE. We perform ongoing reassessments of all VIEs to determine if the primary beneficiary status has changed.

We own an 85% interest in the Stonewall VIE and are the primary beneficiary, therefore Stonewall is consolidated. We own a 50% interest in the South Romeo VIE and are the primary beneficiary, therefore South Romeo is consolidated.

DT Midstream, Inc.

Notes to Consolidated Financial Statements

(Unaudited)

The following table summarizes the major line items in the Consolidated Statements of Financial Position for consolidated VIEs as of June 30, 2024 and December 31, 2023. All assets and liabilities of a consolidated VIE are included in the table when it has been determined that a consolidated VIE has either (1) assets that can be used only to settle obligations of the VIE or (2) liabilities for which creditors do not have recourse to the general credit of the primary beneficiary. The assets and liabilities of consolidated VIEs that meet the definition of a business and whose assets can be used for purposes other than the settlement of the VIEs' obligations have been excluded from the table below.

Related Parties

Transactions between DT Midstream and our equity method investees have been presented as related party transactions in the accompanying Consolidated Financial Statements.

Equity Method Investments

Non-controlled investments are accounted for using the equity method of accounting when we are able to significantly influence the operating policies of the investee. Under the equity method of accounting, investments are recorded at historical cost as an asset and adjusted for capital contributions, dividends and distributions received, and our share of the investee's earnings or losses, which are recorded as earnings from equity method investees on the Consolidated Statements of Operations. Our equity method investments are periodically evaluated for certain factors that may be indicative of other-than-temporary impairment. As of June 30, 2024 and December 31, 2023, our carrying amounts of investments in equity method investees exceeded our share of the underlying equity in the net assets of the investees by $344 million and $352 million, respectively. The difference will be amortized over the life of the underlying assets. As of June 30, 2024 and December 31, 2023, our consolidated retained earnings balance did not have undistributed earnings from equity method investments. We use the cumulative earnings approach to classify proceeds received from equity method investees as dividends or distributions on the Consolidated Statements of Cash Flows.

In May 2023, NEXUS closed on the sale of $750 million of senior unsecured notes with a weighted-average coupon rate of 5.52%. We received a distribution from NEXUS of $371 million, net of fees and expenses, which reduced our investment balance. We used the proceeds from the distribution to repay borrowings outstanding under our Revolving Credit Facility.

The following table presents summarized financial information of our non-consolidated equity method investees. The amounts included below represent 100% of the results of continuing operations of such entities, including the portion owned by other parties.

NOTE 2 — SIGNIFICANT ACCOUNTING POLICIES

Cash and Cash Equivalents

Cash and cash equivalents include cash in banks and highly liquid money market investments with remaining maturities of three months or less, when purchased. Cash equivalents are stated at cost, which approximates fair value.

Financing Receivables

Financing receivables are primarily composed of trade accounts receivable and notes receivable, which are stated at net realizable value.

We regularly monitor the credit quality of our financing receivables by reviewing counterparty credit quality indicators and monitoring for triggering events, such as a credit rating downgrade or bankruptcy. We have three internal grades of credit quality, with internal grade 1 as the lowest risk and internal grade 3 as the highest risk. The related credit quality indicators and risk ratings utilized to develop the internal grades have been updated through June 30, 2024. As of June 30, 2024, the Notes receivable — related party of $4 million, which originated prior to 2021, was classified as internal grade 1. There are no notes receivable on nonaccrual status and no past due financing receivables as of June 30, 2024.

For trade accounts receivable, the customer allowance for expected credit loss is calculated based on specific review of future collections based on receivable balances generally in excess of 30 days. Existing and future economic conditions, historical loss rates, customer trends and other relevant factors that may affect our ability to collect are also considered. Receivables are written off on a specific identification basis and determined based on the particular circumstances of the associated receivable. Uncollectible expense (recovery) was zero for each of the three and six months ended June 30, 2024 and 2023.

Our collections on accounts receivable from customers are current, and no material rate of historical loss was noted, which resulted in no allowance for expected credit loss as of June 30, 2024 or December 31, 2023. Any balance would be shown as a deduction from the respective financing receivable's balance in the Consolidated Statements of Financial Position.

Operation and Maintenance

Operation and maintenance is primarily comprised of costs for labor and employee benefits, outside services, materials, compression, purchased natural gas, operating lease costs, office costs, and other operating and maintenance costs.

NOTE 3 — NEW ACCOUNTING PRONOUNCEMENTS

Recently Issued Pronouncements

In November 2023, the FASB issued ASU No. 2023-07, Segment Reporting (Topic 280) - Improvements to Reportable Segment Disclosures. The amendments improve reportable segment disclosure requirements, primarily through enhanced disclosures about significant segment expenses and interim disclosure requirements. The amendments are effective for fiscal years beginning after December 15, 2023 and interim periods within fiscal years beginning after December 15, 2024. Early adoption is permitted. We continue to evaluate the impact of this standard's adoption on our Consolidated Financial Statements.

In December 2023, the FASB issued ASU No. 2023-09, Income Taxes (Topic 740) - Improvements to Income Tax Disclosures. The amendments improve transparency of income tax disclosure requirements, primarily through enhanced disclosures of rate reconciliation and income taxes paid. The amendments are effective for annual periods beginning after December 15, 2024. Early adoption is permitted. We continue to evaluate the impact of this standard's adoption on our Consolidated Financial Statements.

NOTE 4 — GOODWILL

We have goodwill that resulted from business combinations. The carrying value of goodwill is evaluated for impairment on an annual basis or whenever events or circumstances indicate that the value of goodwill may be impaired. We performed our prior year annual impairment test as of October 1, 2023 and determined that the estimated fair value of each reporting unit exceeded its carrying value, and no impairment existed. No additions, impairments or other changes occurred during the three and six months ended June 30, 2024.

The following is the summary of the carrying value of goodwill:



	June 30,		December 31,
	2024		2023
	(millions)
Pipeline	$	53	$	53
Gathering	420		420
Total goodwill	$	473	$	473

While we believe the estimates and assumptions in the estimated fair value are reasonable, the actual results may differ from projections. To the extent projected results or cash flows are revised downward, the reporting unit may be required to write down all or a portion of its goodwill, which would adversely impact our earnings. If current expectations of future long-term growth are not met or market factors outside of our control change, such as U.S. Treasury Rates or declines in midstream industry transaction multiples, this may lead to a goodwill impairment in the future.

__________________________________

(a)Includes revenues outside the scope of ASC 606 primarily related to contracts accounted for as leases of $2 million for both the three months ended June 30, 2024 and 2023, and $4 million and $3 million for the six months ended June 30, 2024 and 2023, respectively.

Nature of Services

We primarily provide two types of revenue services: firm service and interruptible service. Firm service revenue contracts provide for fixed revenue commitments regardless of actual volumes of natural gas that flow, which leads to more stable operating performance, revenues and cash flows and limits our exposure to natural gas price fluctuations. Firm service revenue contracts are typically long-term and structured using fixed demand charges or MVCs with fixed deficiency fee rates. Contracts structured using fixed demand charges contain a performance obligation of a stand-ready series of distinct services that are substantially the same with the same pattern of transfer to the customer, therefore revenue is recognized ratably over time. Contracts structured using MVCs with fixed deficiency fee rates require customers to transport or store a minimum volume of natural gas over a specified time period. If a customer fails to meet its MVCs for the specified time period, the contract consideration includes a fixed rate for the actual volumes gathered, transported or stored, and a deficiency fee for the shortfall between the MVCs and the actual volumes gathered, transported, or stored. If a customer exceeds its MVC for the specified time period, the contract consideration is based on fixed rates for the actual volumes gathered, transported, or stored. The contract consideration is allocated to each distinct monthly performance obligation, consistent with the allocation objective and based upon the level of effort required to satisfy the service obligation. Revenues are generally recognized over time based on the output measure of natural gas volumes gathered, transported, or stored, with the recognition of the deficiency fee revenue in the period when it is known the customer cannot make up the deficient volumes in the specified time period. Interruptible service revenue contracts typically contain fixed rates, with total consideration dependent on actual natural gas volumes that flow. Interruptible service revenues are recognized over time based on the output measure of natural gas volumes gathered, transported, or stored. Certain of our gathering contracts allow for the recovery of production-related operating expenses, which are offsetting in revenue and operating expense.

Contract Liabilities

The following is a summary of contract liability activity:


	2024

Balance as of January 1	$	129
Increases due to cash received or receivable, excluding amounts recognized as revenue during the period	29

Balance as of June 30	$	146

Contract liabilities generally represent amounts paid by or receivable from customers for which the associated performance obligation has not yet been satisfied. Contract liabilities associated with these services are recognized upon delivery of the service to the customer.

Transaction Price Allocated to the Remaining Performance Obligations

In accordance with optional exemptions available under ASC 606, we do not disclose the value of unsatisfied performance obligations for (1) contracts with an original expected length of one year or less, (2) with the exception of fixed consideration, contracts for which the amount of revenue recognized depends upon our invoices for actual volumes gathered, transported, or stored, and (3) contracts for which variable consideration relates entirely to an unsatisfied performance obligation.

Such contracts consist of various types of performance obligations, including providing midstream services. Contracts with variable volumes and/or variable pricing, including those with pricing provisions tied to a consumer price or other index, have also been excluded as the related contract consideration is variable at the contract inception. Contract lengths vary from cancellable to multi-year.

The following table presents revenue amounts related to fixed consideration associated with unsatisfied performance obligations as of June 30, 2024 that are expected to be recognized as revenue in future periods:


	(millions)
Remainder of 2024	$	69

2026	128
2027	97
2028	65
2029 and thereafter	230
Total	$	739

Costs to Obtain or Fulfill a Contract

We recognize an asset from the costs incurred to obtain a revenue contract only if we expect to recover those costs. In addition, the costs to fulfill a revenue contract are capitalized if the costs are specifically identifiable to a revenue contract, would result in enhancing resources that will be used in satisfying performance obligations in the future, and are expected to be recovered. These capitalized costs are amortized on a systematic basis consistent with the pattern of transfer of the services to which such costs relate.

As of both June 30, 2024 and December 31, 2023, we had capitalized costs to obtain or fulfill a contract of $18 million, which are included in other current assets and other noncurrent assets in the accompanying Consolidated Statements of Financial Position. During the three and six months ended June 30, 2024 and 2023 we recognized less than $1 million of amortization expense related to such capitalized costs.

NOTE 6 — EARNINGS PER SHARE AND DIVIDENDS

Basic earnings per share is calculated by dividing Net Income attributable to DT Midstream by the weighted-average number of common shares outstanding during the period. Diluted earnings per share reflect the dilution that would occur if any potentially dilutive instruments were exercised or converted into common shares, using the treasury stock method. Restricted stock units and performance share awards, including dividend equivalents on those grants, are potentially dilutive and, if dilutive, are included in the determination of weighted-average shares outstanding. Restricted stock units and performance share awards do not receive cash dividends, as such, these awards are not considered participating securities.

The following is a reconciliation of basic and diluted earnings per share:


	Three Months Ended				Six Months Ended
	June 30,				June 30,

NOTE 7 — INCOME TAXES

Effective Tax Rates

We record income taxes during the interim period using an estimated annual ETR and recognize specific events discretely as they occur.

The interim period ETRs of DT Midstream were 25% and 24% for the three months ended June 30, 2024 and 2023, respectively, and 24% and 28% for the six months ended June 30, 2024 and 2023, respectively.

The difference between the interim period ETR and federal statutory rate of 21% is primarily related to state income taxes. The decrease in the interim ETR for the comparative six-month period is driven by the remeasurement of state deferred taxes recognized in 2023 due to changes in tax status and apportionment rates, resulting in a lower ETR in 2024.

NOTE 8 — FAIR VALUE

Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date in a principal or most advantageous market. Fair value is a market-based measurement that is determined based on inputs, which refer broadly to assumptions that market participants use in pricing assets or liabilities. These inputs can be readily observable, market corroborated, or generally unobservable inputs. We make certain assumptions we believe that market participants would use in pricing assets or liabilities, including assumptions about risk, and the risks inherent in the inputs to valuation techniques. We believe we use valuation techniques that maximize the use of observable market-based inputs and minimize the use of unobservable inputs.

A fair value hierarchy has been established that prioritizes the inputs to valuation techniques used to measure fair value in three broad levels. The fair value hierarchy gives the highest priority to quoted prices (unadjusted) in active markets for identical assets or liabilities (Level 1) and the lowest priority to unobservable inputs (Level 3). In some cases, the inputs used to measure fair value might fall in different levels of the fair value hierarchy. All assets and liabilities are required to be classified in their entirety based on the lowest level of input that is significant to the fair value measurement in its entirety. Assessing the significance of a particular input may require judgment considering factors specific to the asset or liability and may affect the valuation of the asset or liability and its placement within the fair value hierarchy. We classify fair value balances based on the fair value hierarchy defined as follows:

•Level 1 — Consists of unadjusted quoted prices in active markets for identical assets or liabilities that we have the ability to access as of the reporting date.

•Level 2 — Consists of inputs other than quoted prices included within Level 1 that are directly observable for the assets or liabilities or indirectly observable through corroboration with observable market data.

•Level 3 — Consists of unobservable inputs for assets or liabilities whose fair value is estimated based on internally developed models or methodologies using inputs that are generally less readily observable and supported by little, if any, market activity at the measurement date. Unobservable inputs are developed based on the best available information and subject to cost-benefit constraints.

The Credit Agreement covering the Term Loan Facility and Revolving Credit Facility includes financial covenants that we must maintain. These covenants restrict the ability of DT Midstream and our subsidiaries to incur additional indebtedness and guarantee indebtedness, create or incur liens, engage in mergers, consolidations, liquidations or dissolutions, sell, transfer or otherwise dispose of assets, make investments, acquisitions, loans or advances, pay dividends and distributions or repurchase capital stock, prepay, redeem or repurchase certain junior indebtedness, enter into agreements that limit the ability of the restricted subsidiaries to make distributions to DT Midstream or the ability of DT Midstream and our restricted subsidiaries to incur liens on assets and enter into certain transactions with affiliates. The Term Loan Facility requires the maintenance of a minimum debt service coverage ratio of 1.1 to 1, and the Revolving Credit Facility requires maintenance of (i) a maximum consolidated net leverage ratio of 5 to 1, and (ii) a minimum interest coverage ratio of no less than 2.5 to 1. The debt service coverage ratio means the ratio of annual consolidated EBITDA to debt service, as defined in the Credit Agreement. The consolidated net leverage ratio means the ratio of net debt determined in accordance with GAAP to annual consolidated EBITDA. The interest coverage ratio means the ratio of annual consolidated EBITDA to annual interest expense, as defined in the Credit Agreement. The Credit Agreement definition of annual consolidated EBITDA excludes EBITDA from equity method investees, but includes dividends and distributions from equity method investees. As of June 30, 2024, the debt service coverage ratio, the consolidated net leverage ratio and the interest coverage ratio was 6.3 to 1, 3.1 to 1 and 5.9 to 1, respectively, and we were in compliance with these financial covenants.

NOTE 10 — COMMITMENTS AND CONTINGENCIES

From time to time, we are subject to legal, administrative and environmental proceedings before various courts, arbitration panels and governmental agencies concerning claims arising in the ordinary course of business. These proceedings include certain contract disputes, additional environmental reviews and investigations, audits and pending judicial matters. We cannot predict the final disposition of such proceedings. We regularly review legal matters and record provisions for claims that we can estimate and are considered probable of loss. The amount or range of reasonably possible losses is not anticipated to, either individually or in the aggregate, materially adversely affect our business, financial condition and results of operations.

Guarantees

In certain limited circumstances, we enter into contractual guarantees. We may guarantee another entity's obligation in the event it fails to perform and may provide guarantees in certain indemnification agreements. We did not have any guarantees of other parties' obligations as of June 30, 2024.

Surety Bonds

In certain limited circumstances, we enter into contracts that require us to obtain external surety bonds to secure our payment and performance. We agree to indemnify the issuers of these surety bonds for amounts, if any, paid by them under these agreements. In the event that any surety bonds are called for non-performance, we would be obligated to reimburse the issuer of the surety bond. The maximum potential indemnification under our surety bond agreements as of June 30, 2024 is $31 million.

Vector Line of Credit

We are the lender under a revolving term credit facility to Vector, the borrower, in the amount of Canadian $70 million. The credit facility was executed in response to the passage of Canadian regulations requiring oil and gas pipelines to demonstrate their financial ability to respond to a catastrophic event and exists for the sole purpose of satisfying these regulations. Vector may only draw upon the facility if the funds are required to respond to a catastrophic event. The maximum potential payout as of June 30, 2024 is USD $51 million. The funding of a loan under the terms of the revolving term credit facility is considered remote.

Contingent Liability

In order to comply with certain state environmental regulations, we have an obligation to restore pipeline right-of-way slope failures that may arise in the ordinary course of business in the Utica and Marcellus formations. We completed evaluations of all locations, which were prioritized based on the severity and proximity of the slope failures, and used updated cost information to assess the adequacy of the estimate for the contingent liability accrual. Based on these evaluations, we recorded a reduction to the contingent liability accrual and decrease to operation and maintenance expense of $9 million during the three months ended June 30, 2024. As of June 30, 2024 and December 31, 2023, we had accrued contingent liabilities of $4 million and $13 million, respectively, for future slope restoration expenditures. The accrual is included in other current liabilities and other liabilities in the Consolidated Statements of Financial Position. While restoration is ongoing, we believe the accrued amounts are sufficient to cover estimated future expenditures.

NOTE 11 — SEGMENT AND RELATED INFORMATION

We set strategic goals, allocate resources, and evaluate performance based on the following structure:

The Pipeline segment owns and operates interstate and intrastate natural gas pipelines, storage systems, and natural gas gathering lateral pipelines. The segment also has interests in equity method investees that own and operate interstate natural gas pipelines. The Pipeline segment is also engaged in the transportation and storage of natural gas for intermediate and end user customers.

The Gathering segment owns and operates gas gathering systems. The segment is engaged in collecting natural gas from points at or near customers’ wells for delivery to plants for treating, to gathering pipelines for further gathering, or to pipelines for transportation, as well as associated ancillary services, including compression, dehydration, gas treatment, water impoundment, water transportation, water disposal, and sand mining.

Inter-segment billing for goods and services exchanged between segments is based upon contracted prices of the provider. Inter-segment billings were not significant for the three and six months ended June 30, 2024 and 2023.

The following tables present financial data by business segment:

NOTE 12 — SUBSEQUENT EVENTS

Dividend Declaration

On July 30, 2024, we announced that our Board of Directors declared a quarterly dividend of $0.735 per share of common stock. The dividend is payable to our stockholders of record as of September 16, 2024 and is expected to be paid on October 15, 2024.

Clean Fuels Gathering Project Acquisition

On July 1, 2024, DT Midstream closed on the purchase of a clean fuels gathering project from a privately-held coal mine methane producer for a cash payment of $12 million. The acquisition was comprised of gathering and treating assets that process coal mine methane into pipeline quality natural gas. The acquisition aligns with our strategy to pursue economically attractive opportunities and deploy GHG reducing technologies and is expected to generate carbon offsets and federal income tax credits for clean fuel production. A contingent payment of $10 million is expected to be paid within the next 12 months upon the completion of a milestone. Additionally, if certain cumulative production and income tax credit milestones are achieved, DT Midstream will be required to make incremental contingent payments in future years of up to $24 million and variable payments under a sharing mechanism that could be material.

Due to the timing of the acquisition subsequent to June 30, 2024, certain accounting and disclosures, including whether the acquisition will be treated as a business combination or asset acquisition, and the allocation of purchase price, will be finalized and recorded in our subsequent quarterly report on the Form 10-Q.

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

The following discussion of our results of operations and financial condition should be read in conjunction with our unaudited Consolidated Financial Statements and the Notes to Consolidated Financial Statements, which are included under Part I, Item 1. of this quarterly report, and the historical consolidated financial statements and notes thereto, which are included in the DT Midstream 2023 Annual Report on Form 10-K. This discussion contains forward-looking statements that involve risks and uncertainties. The forward-looking statements are not historical facts, but rather are based on current expectations, estimates, assumptions and projections about the midstream industry and our business and financial results. Our actual results could differ materially from the results contemplated by these forward-looking statements due to a number of factors, including those discussed in the sections entitled "Forward-Looking Statements" and "Risk Factors."

OVERVIEW

Our Business

We are an owner, operator, and developer of an integrated portfolio of natural gas midstream assets. We provide multiple, integrated natural gas services to customers through our Pipeline segment, which includes interstate pipelines, intrastate pipelines, storage systems, and gathering lateral pipelines, and through our Gathering segment. We also own joint venture interests in equity method investees which own and operate interstate pipelines that connect to our wholly owned assets.

Our core assets strategically connect key demand centers in the Midwestern U.S., Eastern Canada and Northeastern U.S. regions to the premium production areas of the Marcellus/Utica natural gas formation in the Appalachian Basin and connect key demand centers and LNG export terminals in the Gulf Coast region to premium production areas of the Haynesville natural gas formation.

We have an established history of stable, long-term growth with contractual cash flows from customers that include natural gas producers, local distribution companies, electric power generators, industrials, and national marketers.

STRATEGY

Our principal business objective is to safely and reliably operate and develop natural gas assets across our premier footprint. Our proven leadership and highly engaged employees have an excellent track record. Prospectively, we intend to continue this track record by executing on our natural gas-centric business strategy focused on disciplined capital deployment and supported by a flexible, well capitalized balance sheet. Additionally, we intend to develop low carbon business opportunities and deploy GHG reducing technologies as part of our goal of being leading environmental stewards in the midstream industry. We are executing on our goal to achieve net zero carbon emissions by 2050.

Our strategy is premised on the following principles:

•operate our assets in a sustainable and responsible manner;

•provide exceptional service to our customers;

•disciplined capital deployment in assets supported by strong fundamentals;

•capitalize on asset integration and utilization opportunities;

•pursue economically attractive opportunities; and

•grow cash flows supported by long-term firm revenue contracts.

RESULTS OF OPERATIONS

Management’s Discussion and Analysis of Financial Condition and Results of Operations includes financial information prepared in accordance with GAAP. The following sections discuss the operating performance and future outlook of our segments. Segment information includes intercompany revenues and expenses, as well as other income and deductions that are eliminated in the Consolidated Financial Statements.

For purposes of the following discussion, any increases or decreases refer to the comparison of the three months ended June 30, 2024 to the three months ended March 31, 2024, and the six months ended June 30, 2024 to the six months ended June 30, 2023, as applicable. The following table summarizes our consolidated financial results:

Operating revenues increased $2 million for the three months ended June 30, 2024 primarily due to new contracts and expansion of the Haynesville System (LEAP) of $4 million and higher long-term storage contracting rates at Washington 10 Storage Complex of $2 million, partially offset by lower volumes on Stonewall and Bluestone. Operating revenues increased $41 million for the six months ended June 30, 2024 primarily due to new contracts and expansion of the Haynesville System (LEAP) of $30 million, higher Stonewall volumes of $6 million, and higher long-term storage contracting rates at Washington 10 Storage Complex of $5 million.

Operation and maintenance expense increased $6 million for the six months ended June 30, 2024 primarily due to operational flow order fee activity in the prior period and higher operation and maintenance expenses at LEAP in the current period.

Depreciation and amortization expense increased $4 million for the six months ended June 30, 2024 primarily due to new Haynesville System (LEAP) assets placed into service.

Taxes other than income increased $4 million for the six months ended June 30, 2024 primarily due to new Haynesville System (LEAP) assets placed into service resulting in higher property taxes.

Asset (gains) losses and impairments, net decreased $3 million for the six months ended June 30, 2024 due to a one-time gain realized from an insurance settlement that occurred during the six months ended June 30, 2023.

Interest expense decreased $4 million for the six months ended June 30, 2024 primarily due to lower outstanding borrowings under the Revolving Credit Facility, partially offset by lower capitalized interest due to lower construction in progress during 2024 and higher interest rates on the Term Loan Facility.

Earnings from equity method investees decreased $7 million for the three months ended June 30, 2024 primarily due to lower seasonal short-term contracting revenues of $3 million each at Millennium and Vector. Earnings from equity method investees decreased $6 million for the six months ended June 30, 2024 primarily due to higher interest expense driven by timing of new senior unsecured notes at NEXUS of $5 million.

Pipeline Outlook

We believe our long-term agreements with customers and the location and connectivity of our pipeline assets position the business for future growth. We will continue to pursue economically attractive expansion opportunities that leverage our current asset footprint and strategic relationships. These growth opportunities include further expansion at the Haynesville System (LEAP) and Stonewall, new contracts at the Washington 10 Storage Complex, and additional growth related to our equity method investments.

Gathering

The Gathering segment includes gathering systems, related treatment plants and compression and surface facilities. Gathering results and outlook are discussed below:

Operating revenues increased $2 million for the three months ended June 30, 2024 primarily due to higher contract rates from Appalachia Gathering of $3 million and new assets placed into service on Ohio Utica Gathering of $2 million, partially offset by lower Susquehanna Gathering volumes of $2 million. Operating revenues decreased $1 million for the six months ended June 30, 2024 primarily due to lower volumes and recovery of production related operating expenses on Blue Union Gathering of $14 million and lower Susquehanna Gathering volumes of $4 million, partially offset by higher Appalachia Gathering rates and volumes of $11 million, net of lower MVC deficiency fee revenues, and a new customer contract on Ohio Utica Gathering of $7 million.

Operation and maintenance expense decreased $1 million for the three months ended June 30, 2024 primarily due to a reduction in Appalachia Gathering environmental contingent liabilities of $9 million, partially offset by higher planned maintenance on Blue Union Gathering of $6 million. Operation and maintenance expense decreased $18 million for the six months ended June 30, 2024 primarily due to lower planned maintenance and production related operating expenses on Blue Union Gathering of $10 million and a reduction in Appalachia Gathering environmental contingent liabilities of $9 million.

Depreciation and amortization expense increased $12 million for the six months ended June 30, 2024 primarily due to assets placed into service at Blue Union Gathering and Ohio Utica Gathering.

Interest expense increased $10 million for the six months ended June 30, 2024 primarily due to lower capitalized interest due to lower construction in progress during 2024 and higher interest rates on the Term Loan Facility, partially offset by lower outstanding borrowings under the Revolving Credit Facility.

Income tax expense decreased $4 million for the six months ended June 30, 2024 primarily due to the remeasurement of state deferred taxes recognized in 2023 and a decrease in Income before income taxes. See Note 7, "Income Taxes" to the Consolidated Financial Statements under Part I, Item 1 of this Form 10-Q.

Gathering Outlook

We believe our long-term agreements with producers and the quality of the natural gas reserves in the Marcellus/Utica and Haynesville formations position the business for future growth. We will continue to pursue economically attractive expansion opportunities that leverage our current asset footprint and strategic relationships. These growth opportunities include further expansion at the Haynesville System (Blue Union Gathering), Appalachia Gathering, Ohio Utica Gathering and Tioga Gathering.

ENVIRONMENTAL MATTERS

We are subject to extensive U.S. federal, state, and local environmental regulations. Additional compliance costs may result as the effects of various substances on the environment are studied and governmental regulations are developed and implemented. Actual costs to comply with such regulation could vary substantially from our expectations. Pending or future legislation or regulation could have a material impact on our operations and financial position. Potential impacts include unplanned expenditures for environmental equipment, such as pollution control equipment, financing costs related to additional capital expenditures, and the replacement costs of aging pipelines and other facilities.

For further discussion of environmental matters, see Note 10, "Commitments and Contingencies" to the Consolidated Financial Statements under Part I, Item 1. of this Form 10-Q.

CAPITAL RESOURCES AND LIQUIDITY

Cash Requirements

Our principal liquidity requirements are to finance our operations, fund capital expenditures, satisfy our indebtedness obligations, and pay approved dividends. We believe we will have sufficient internal and external capital resources to fund anticipated capital and operating requirements.


	Six Months Ended
	June 30,
	2024		2023
	(millions)
Cash and Cash Equivalents at Beginning of Period	$	56	$	61

Net Increase (Decrease) in Cash and Cash Equivalents	17		(16)
Cash and Cash Equivalents at End of Period	$	73	$	45

For purposes of the following discussion, any increases or decreases refer to the comparison of the six months ended June 30, 2024 to the six months ended June 30, 2023.

Operating Activities

Cash flows from our operating activities can be impacted in the short term by the natural gas volumes gathered or transported through our systems under interruptible service revenue contracts, changing natural gas prices, seasonality, weather fluctuations, dividends received from equity method investees and the financial condition of our customers. Our preference to enter into firm service revenue contracts leads to more stable operating performance, revenues and cash flows and limits our exposure to natural gas price fluctuations.

Net cash and cash equivalents from operating activities increased $17 million for the six months ended June 30, 2024 primarily due to an increase in operating income after adjustment for non-cash items including depreciation and amortization expense, stock-based compensation, and amortization of operating lease right-of-use assets, partially offset by a decrease in dividends received from equity method investees and a decrease in interest expense.

Investing Activities

Cash outflows associated with our investing activities are primarily the result of plant and equipment expenditures, acquisitions, and contributions to equity method investees. Cash inflows from our investing activities are generated from proceeds from sale or collection of notes receivable, distributions received from equity method investees, and proceeds from asset sales.

Net cash and cash equivalents used for investing activities increased $112 million for the six months ended June 30, 2024 primarily due to lower distributions received from equity method investees driven by the NEXUS distribution related to senior unsecured notes in 2023. This change was partially offset by a decrease in cash used for plant and equipment expenditures and lower contributions paid to equity method investees in 2024.

Financing Activities

DT Midstream paid cash dividends on common stock of $138 million and $129 million during the six months ended June 30, 2024 and 2023, respectively. See Note 6, "Earnings Per Share and Dividends" to the Consolidated Financial Statements under Part I, Item 1. of this Form 10-Q.

Net cash and cash equivalents used for financing activities decreased $128 million for the six months ended June 30, 2024 primarily due to lower net repayments of borrowings under the Revolving Credit Facility, partially offset by higher dividends paid on common stock.

Outlook

We expect to continue executing on our natural gas-centric business strategy focused on disciplined capital deployment and supported by a flexible, well capitalized balance sheet. Other than the impact of the items discussed below on our debt and equity capitalization, we are not aware of any trends, other demands, commitments, events or uncertainties that are reasonably likely to materially impact our liquidity position.

Our working capital requirements will be primarily driven by changes in accounts receivable and accounts payable. We continue our efforts to identify opportunities to improve cash flows through working capital initiatives and obtaining long-term firm service revenue contracts from customers.

Our sources of liquidity include cash and cash equivalents generated from operating activities and available borrowings under our Revolving Credit Facility. As of June 30, 2024, we had $16 million of letters of credit outstanding and $70 million of borrowings outstanding under our Revolving Credit Facility. We had approximately $987 million of available liquidity as of June 30, 2024, consisting of cash and cash equivalents and available borrowings under our Revolving Credit Facility.

We expect to pay regular cash dividends to DT Midstream common stockholders in the future. Any payment of future dividends is subject to approval by the Board of Directors and may depend on our future earnings, cash flows, capital requirements, financial condition, and the effect a dividend payment would have on our compliance with relevant financial covenants. Over the long-term, we expect to grow our dividend 5% to 7% annually.

We believe we will have sufficient operating flexibility, cash resources and funding sources to maintain adequate liquidity amounts and to meet future operating cash, capital expenditure and debt servicing requirements. However, our business is capital intensive, and the inability to access adequate capital could adversely impact future earnings and cash flows.

The Credit Agreement covering the Term Loan Facility and Revolving Credit Facility includes financial covenants that DT Midstream must maintain. See Note 9, "Debt" to the Consolidated Financial Statements under Part I, Item 1. of this Form 10-Q.

See also Note 10, "Commitments and Contingencies" and Note 12, "Subsequent Events" to the Consolidated Financial Statements under Part I, Item 1. of this Form 10-Q.

CAPITAL INVESTMENTS

Capital spending within our Company is primarily for ongoing maintenance and expansion of our existing assets, and if identified, attractive growth opportunities. We have been disciplined in our capital deployment and make growth investments that meet our criteria in terms of strategy, management skills, and identified risks and expected returns. All potential investments are analyzed for their rates of return and cash payback on a risk-adjusted basis. Our total capital expenditures, inclusive of $1 million in contributions to equity method investees, were $180 million for the six months ended June 30, 2024 primarily for expansions on Ohio Utica Gathering, Blue Union Gathering and LEAP. We anticipate total capital expenditures, inclusive of contributions to equity method investees, for the year ended December 31, 2024 of approximately $380 million to $435 million.

CRITICAL ACCOUNTING ESTIMATES

The preparation of our Consolidated Financial Statements in conformity with GAAP requires that management applies accounting policies and makes estimates and assumptions that affect results of operations and the amounts of assets and liabilities reported in the Consolidated Financial Statements. Management believes that the area described below requires significant judgment in the application of the accounting policy or in making estimates and assumptions in matters that are inherently uncertain and that may change in subsequent periods.

Goodwill

We have goodwill that resulted from business combinations. Annually as of October 1st, an impairment test for goodwill is performed which compares the fair value of each reporting unit to its carrying value including goodwill. In between annual impairment tests, we monitor our estimates and assumptions regarding estimated future cash flows, including the impact of movements in market indicators. An interim impairment test is performed whenever a triggering event occurs or circumstances indicate that the value of goodwill may be impaired.

The estimated fair value in our annual goodwill impairment analysis utilizes significant assumptions that require judgment by management. One such significant assumption is the weighted average cost of capital (WACC) which is used to discount estimates of projected future results and cash flows to be generated by each reporting unit. The WACC is based on our cost of debt, which includes U.S. industrial bond spreads, and cost of equity, which consists of U.S. Treasury Rates plus an equity risk premium. We have noted that U.S. Treasury risk-free rates have decreased slightly since our last annual goodwill impairment test.

Our annual goodwill impairment analysis includes a comparison of the estimated fair value of the Company as a whole to our market capitalization. Management also compares the implied market multiple of the estimated fair value of each reporting unit to midstream industry transaction multiples and considers other market indicators to support the appropriateness of the fair value estimates. Our consolidated market capitalization has increased since our last annual goodwill impairment test. We have noted a slight decline in gathering-related midstream industry transaction multiples since our last annual goodwill impairment test. After assessing all relevant facts and circumstances, we have concluded that no triggering event has occurred that indicates it is more likely than not that the goodwill is impaired for either reporting unit and determined that an interim impairment test is not required. We will continue to monitor our estimates and assumptions on a quarterly basis as market conditions continue to evolve.

While we believe the estimates and assumptions in the fair value are reasonable, the actual results may differ from projections. To the extent projected results or cash flows are revised downward, the reporting unit may be required to write down all or a portion of its goodwill, which would adversely impact our earnings. If current expectations of future long-term growth are not met or market factors outside of our control change, such as U.S. Treasury Rates, a decline in our market capitalization, or a further decline in midstream industry transaction multiples, this may lead to a goodwill impairment in the future.

See Part I, Item 3., "Quantitative and Qualitative Disclosures About Market Risk", in this Form 10-Q for more information on our exposure to market risk. See also "Critical Accounting Estimates" included in DT Midstream's 2023 Annual Report on Form 10-K.

OFF-BALANCE SHEET ARRANGEMENTS

We are party to off-balance sheet arrangements, which include our equity method investments. See Note 1, "Description of the Business and Basis of Presentation—Principles of Consolidation" to the Consolidated Financial Statements under Part I, Item 1. of this Form 10-Q for further discussion of the nature, purpose and other details of such agreements.

Other off-balance sheet arrangements include the Vector line of credit and our surety bonds, which are discussed further in Note 10, "Commitments and Contingencies" to the Consolidated Financial Statements under Part I, Item 1. of this Form 10-Q.

NEW ACCOUNTING PRONOUNCEMENTS

See Note 3, "New Accounting Pronouncements" to the Consolidated Financial Statements under Part I, Item 1. of this Form 10-Q.

Item 3. Quantitative and Qualitative Disclosures About Market Risk

Market Price Risk

Our business is dependent on the continued availability of natural gas production and reserves in our geographical areas of operation. Low prices for natural gas, including those resulting from regional basis differentials, could adversely affect development of additional reserves and future natural gas production that is accessible by our pipeline and storage assets. We manage our exposure through the use of short, medium, and long-term transportation, gathering, and storage contracts. Consequently, our existing operations and cash flows have limited direct exposure to natural gas price risk.

Credit Risk

We are exposed to credit risk, which is the risk of loss resulting from nonpayment or nonperformance under a contract. We manage our exposure to credit risk associated with customers through credit analysis, credit approval, credit limits and monitoring procedures. For certain transactions, we may request letters of credit, cash collateral, prepayments or guarantees as forms of credit support. Our FERC tariffs require tariff customers that do not meet specified credit standards to provide three months of credit support, however, we are exposed to credit risk beyond this three-month period when our tariffs do not require our customers to provide additional credit support. For some long-term contracts associated with gathering system construction or expansion, we have entered into negotiated credit agreements that provide for enhanced forms of credit support if certain customer credit standards are not met.

We depend on a key customer, Southwestern Energy, in the Haynesville formation in the Gulf Coast and in the Utica and Marcellus formations in the Northeastern U.S. for a significant portion of our revenues. The loss of, or reduction in volumes from, this key customer could result in a decline in demand for our services and materially adversely affect our business, financial condition and results of operations.

We engage with customers that are sub-investment grade, including our key customer, Southwestern Energy. These customers are otherwise considered creditworthy or are required to make prepayments or provide security to satisfy credit concerns. We regularly monitor for bankruptcy proceedings that may impact our customers and had no bankruptcy proceedings during the six months ended June 30, 2024.

Interest Rate Risk

We are subject to interest rate risk in connection with the issuance of debt. Our exposure to interest rate risk arises primarily from changes in SOFR. As of June 30, 2024, we had floating rate debt of $469 million related to the variable rate Term Loan Facility and borrowings outstanding under our Revolving Credit Facility, and a floating rate debt-to-total debt ratio of 15%. See Note 9, "Debt" to the Consolidated Financial Statements under Part I, Item 1. of this Form 10-Q.

We are subject to interest rate risk in connection with our goodwill impairment assessment. See "Critical Accounting Estimates" under Part I, Item 2 of this Form 10-Q.

Summary of Sensitivity Analysis

A sensitivity analysis was performed on the fair values of our long-term debt obligations. The sensitivity analysis involved increasing and decreasing interest rates as of June 30, 2024 by a hypothetical 10% and calculating the resulting change in the fair values. The hypothetical losses related to long-term debt would be realized only if we transferred all of our fixed-rate long-term debt to other creditors. The results of the sensitivity analysis are as follows:

Item 4. Controls and Procedures

(a) Evaluation of disclosure controls and procedures

Management of DT Midstream carried out an evaluation, under the supervision and with the participation of DT Midstream's Chief Executive Officer (CEO) and Chief Financial Officer (CFO), of the effectiveness of the design and operation of DT Midstream's disclosure controls and procedures (as defined in Exchange Act Rules 13a-15(e) and 15d-15(e)) as of June 30, 2024, which is the end of the period covered by this report.

(1) The definition of mine under section 3 of the Mine Act includes the mine, as well as other items used in, or to be used in, or resulting from, the work of extracting minerals, such as land, structures, facilities, equipment, machines, tools, and preparation facilities. Unless otherwise indicated, any of these other items associated with a single mine have been aggregated in the totals for that mine.

(2) The whole-dollar amounts included are the total dollar value of all proposed or outstanding assessments, regardless of classification, received from MSHA on or before June 30, 2024 regardless of whether the assessment has been challenged or appealed, for alleged violations occurring during the three months ended June 30, 2024. Citations and orders can be contested and appealed, and as part of that process, are sometimes reduced in severity and amount, and are sometimes dismissed. The number of citations, orders, and proposed assessments vary by inspector and also vary depending on the size and type of the operation.

SIGNIFICANT ACCOUNTING POLICIES	Jun. 30, 2024
Accounting Policies [Abstract]
SIGNIFICANT ACCOUNTING POLICIES	SIGNIFICANT ACCOUNTING POLICIES Cash and Cash Equivalents Cash and cash equivalents include cash in banks and highly liquid money market investments with remaining maturities of three months or less, when purchased. Cash equivalents are stated at cost, which approximates fair value. Financing Receivables Financing receivables are primarily composed of trade accounts receivable and notes receivable, which are stated at net realizable value. We regularly monitor the credit quality of our financing receivables by reviewing counterparty credit quality indicators and monitoring for triggering events, such as a credit rating downgrade or bankruptcy. We have three internal grades of credit quality, with internal grade 1 as the lowest risk and internal grade 3 as the highest risk. The related credit quality indicators and risk ratings utilized to develop the internal grades have been updated through June 30, 2024. As of June 30, 2024, the Notes receivable — related party of $4 million, which originated prior to 2021, was classified as internal grade 1. There are no notes receivable on nonaccrual status and no past due financing receivables as of June 30, 2024. For trade accounts receivable, the customer allowance for expected credit loss is calculated based on specific review of future collections based on receivable balances generally in excess of 30 days. Existing and future economic conditions, historical loss rates, customer trends and other relevant factors that may affect our ability to collect are also considered. Receivables are written off on a specific identification basis and determined based on the particular circumstances of the associated receivable. Uncollectible expense (recovery) was zero for each of the three and six months ended June 30, 2024 and 2023. Our collections on accounts receivable from customers are current, and no material rate of historical loss was noted, which resulted in no allowance for expected credit loss as of June 30, 2024 or December 31, 2023. Any balance would be shown as a deduction from the respective financing receivable's balance in the Consolidated Statements of Financial Position. Operation and Maintenance Operation and maintenance is primarily comprised of costs for labor and employee benefits, outside services, materials, compression, purchased natural gas, operating lease costs, office costs, and other operating and maintenance costs.

Income Tax Disclosure [Abstract]
INCOME TAXES	INCOME TAXES Effective Tax Rates We record income taxes during the interim period using an estimated annual ETR and recognize specific events discretely as they occur. The interim period ETRs of DT Midstream were 25% and 24% for the three months ended June 30, 2024 and 2023, respectively, and 24% and 28% for the six months ended June 30, 2024 and 2023, respectively. The difference between the interim period ETR and federal statutory rate of 21% is primarily related to state income taxes. The decrease in the interim ETR for the comparative six-month period is driven by the remeasurement of state deferred taxes recognized in 2023 due to changes in tax status and apportionment rates, resulting in a lower ETR in 2024.

COMMITMENTS AND CONTINGENCIES	Jun. 30, 2024
Commitments and Contingencies Disclosure [Abstract]
COMMITMENTS AND CONTINGENCIES	COMMITMENTS AND CONTINGENCIES From time to time, we are subject to legal, administrative and environmental proceedings before various courts, arbitration panels and governmental agencies concerning claims arising in the ordinary course of business. These proceedings include certain contract disputes, additional environmental reviews and investigations, audits and pending judicial matters. We cannot predict the final disposition of such proceedings. We regularly review legal matters and record provisions for claims that we can estimate and are considered probable of loss. The amount or range of reasonably possible losses is not anticipated to, either individually or in the aggregate, materially adversely affect our business, financial condition and results of operations. Guarantees In certain limited circumstances, we enter into contractual guarantees. We may guarantee another entity's obligation in the event it fails to perform and may provide guarantees in certain indemnification agreements. We did not have any guarantees of other parties' obligations as of June 30, 2024. Surety Bonds In certain limited circumstances, we enter into contracts that require us to obtain external surety bonds to secure our payment and performance. We agree to indemnify the issuers of these surety bonds for amounts, if any, paid by them under these agreements. In the event that any surety bonds are called for non-performance, we would be obligated to reimburse the issuer of the surety bond. The maximum potential indemnification under our surety bond agreements as of June 30, 2024 is $31 million. Vector Line of Credit We are the lender under a revolving term credit facility to Vector, the borrower, in the amount of Canadian $70 million. The credit facility was executed in response to the passage of Canadian regulations requiring oil and gas pipelines to demonstrate their financial ability to respond to a catastrophic event and exists for the sole purpose of satisfying these regulations. Vector may only draw upon the facility if the funds are required to respond to a catastrophic event. The maximum potential payout as of June 30, 2024 is USD $51 million. The funding of a loan under the terms of the revolving term credit facility is considered remote. Contingent Liability In order to comply with certain state environmental regulations, we have an obligation to restore pipeline right-of-way slope failures that may arise in the ordinary course of business in the Utica and Marcellus formations. We completed evaluations of all locations, which were prioritized based on the severity and proximity of the slope failures, and used updated cost information to assess the adequacy of the estimate for the contingent liability accrual. Based on these evaluations, we recorded a reduction to the contingent liability accrual and decrease to operation and maintenance expense of $9 million during the three months ended June 30, 2024. As of June 30, 2024 and December 31, 2023, we had accrued contingent liabilities of $4 million and $13 million, respectively, for future slope restoration expenditures. The accrual is included in other current liabilities and other liabilities in the Consolidated Statements of Financial Position. While restoration is ongoing, we believe the accrued amounts are sufficient to cover estimated future expenditures.

SUBSEQUENT EVENTS	SUBSEQUENT EVENTS Dividend Declaration On July 30, 2024, we announced that our Board of Directors declared a quarterly dividend of $0.735 per share of common stock. The dividend is payable to our stockholders of record as of September 16, 2024 and is expected to be paid on October 15, 2024. Clean Fuels Gathering Project Acquisition On July 1, 2024, DT Midstream closed on the purchase of a clean fuels gathering project from a privately-held coal mine methane producer for a cash payment of $12 million. The acquisition was comprised of gathering and treating assets that process coal mine methane into pipeline quality natural gas. The acquisition aligns with our strategy to pursue economically attractive opportunities and deploy GHG reducing technologies and is expected to generate carbon offsets and federal income tax credits for clean fuel production. A contingent payment of $10 million is expected to be paid within the next 12 months upon the completion of a milestone. Additionally, if certain cumulative production and income tax credit milestones are achieved, DT Midstream will be required to make incremental contingent payments in future years of up to $24 million and variable payments under a sharing mechanism that could be material. Due to the timing of the acquisition subsequent to June 30, 2024, certain accounting and disclosures, including whether the acquisition will be treated as a business combination or asset acquisition, and the allocation of purchase price, will be finalized and recorded in our subsequent quarterly report on the Form 10-Q.

SIGNIFICANT ACCOUNTING POLICIES (Policies)	Jun. 30, 2024
Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The DT Midstream Consolidated Financial Statements and Notes to Consolidated Financial Statements are prepared under GAAP. These accounting principles require management to use estimates and assumptions that impact reported amounts of assets, liabilities, revenues and expenses, and the disclosure of contingent assets and liabilities. Actual results may differ from our estimates. We believe the assumptions underlying these financial statements are reasonable. In our opinion, the accompanying unaudited Consolidated Financial Statements include all adjustments, consisting of normal recurring adjustments, necessary to present a fair statement of our financial position as of June 30, 2024, results of operations for the three and six months ended June 30, 2024 and 2023, statement of changes in stockholders' equity for the three and six months ended June 30, 2024 and 2023, and cash flows for the six months ended June 30, 2024 and 2023. The balance sheet as of December 31, 2023 was derived from audited annual financial statements but does not include all disclosures required by GAAP. Financial results for this interim period are not necessarily indicative of results that may be expected for any other interim period or for the year ending December 31, 2024. The Consolidated Financial Statements should be read in conjunction with DT Midstream's Consolidated Financial Statements and Notes to Consolidated Financial Statements included in DT Midstream's 2023 Annual Report on Form 10-K.
Principles of Consolidation	Principles of Consolidation We consolidate all majority-owned subsidiaries and investments in entities in which we have a controlling influence. Non-controlled investments are accounted for using the equity method of accounting when we are able to significantly influence the operating policies of the investee. When we do not influence the operating policies of an investee, the equity investment is measured at fair value, if readily determinable, or if not readily determinable, at cost less impairment, if applicable. We eliminate all intercompany balances and transactions. We evaluate whether an entity is a VIE whenever reconsideration events occur. We consolidate VIEs for which we are the primary beneficiary. When assessing the determination of the primary beneficiary, we consider all relevant facts and circumstances, including: the power, through voting or similar rights, to direct the activities of the VIE that most significantly impact the VIE's economic performance and the obligation to absorb the expected losses and/or the right to receive the expected returns of the VIE. We perform ongoing reassessments of all VIEs to determine if the primary beneficiary status has changed.
Cash and Cash Equivalents	Cash and Cash Equivalents Cash and cash equivalents include cash in banks and highly liquid money market investments with remaining maturities of three months or less, when purchased. Cash equivalents are stated at cost, which approximates fair value.
Financing Receivables	Financing Receivables Financing receivables are primarily composed of trade accounts receivable and notes receivable, which are stated at net realizable value. We regularly monitor the credit quality of our financing receivables by reviewing counterparty credit quality indicators and monitoring for triggering events, such as a credit rating downgrade or bankruptcy. We have three internal grades of credit quality, with internal grade 1 as the lowest risk and internal grade 3 as the highest risk. The related credit quality indicators and risk ratings utilized to develop the internal grades have been updated through June 30, 2024. As of June 30, 2024, the Notes receivable — related party of $4 million, which originated prior to 2021, was classified as internal grade 1. There are no notes receivable on nonaccrual status and no past due financing receivables as of June 30, 2024. For trade accounts receivable, the customer allowance for expected credit loss is calculated based on specific review of future collections based on receivable balances generally in excess of 30 days. Existing and future economic conditions, historical loss rates, customer trends and other relevant factors that may affect our ability to collect are also considered. Receivables are written off on a specific identification basis and determined based on the particular circumstances of the associated receivable.
Operation and Maintenance	Operation and Maintenance Operation and maintenance is primarily comprised of costs for labor and employee benefits, outside services, materials, compression, purchased natural gas, operating lease costs, office costs, and other operating and maintenance costs.
Recently Issued Pronouncements	Recently Issued Pronouncements In November 2023, the FASB issued ASU No. 2023-07, Segment Reporting (Topic 280) - Improvements to Reportable Segment Disclosures. The amendments improve reportable segment disclosure requirements, primarily through enhanced disclosures about significant segment expenses and interim disclosure requirements. The amendments are effective for fiscal years beginning after December 15, 2023 and interim periods within fiscal years beginning after December 15, 2024. Early adoption is permitted. We continue to evaluate the impact of this standard's adoption on our Consolidated Financial Statements. In December 2023, the FASB issued ASU No. 2023-09, Income Taxes (Topic 740) - Improvements to Income Tax Disclosures. The amendments improve transparency of income tax disclosure requirements, primarily through enhanced disclosures of rate reconciliation and income taxes paid. The amendments are effective for annual periods beginning after December 15, 2024. Early adoption is permitted. We continue to evaluate the impact of this standard's adoption on our Consolidated Financial Statements.
