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. The Company provides multiple, integrated natural gas services to customers through two segments: (i) Pipeline, which includes interstate pipelines, intrastate pipelines, storage systems, lateral pipelines and related treatment plants and compression and surface facilities, and (ii) Gathering, which includes gathering systems and related treatment plants, and compression and surface facilities. DT Midstream's Pipeline segment also includes interests in equity method investees which own and operate interstate pipelines, which have connectivity to DT Midstream’s assets.

DT Midstream’s core assets connect demand centers in the Midwestern U.S., Eastern Canada, Northeastern U.S. and Gulf Coast regions to production areas of the Haynesville and Marcellus/Utica dry natural gas formations in the Gulf Coast and Appalachian Basins, respectively.

In connection with the Separation from DTE Energy, on January 13, 2021, DTE Gas Enterprises, LLC, and its consolidated subsidiaries converted into a Delaware corporation pursuant to a statutory conversion and changed its name to DT Midstream, Inc. ("DT Midstream"). At the conversion, DT Midstream issued 1,000 shares of common stock at $0.01 par value to its parent, a subsidiary of DTE Energy. As DT Midstream was a single member LLC as of December 31, 2020, and a corporation with stockholders' equity as of September 30, 2022 and 2021, Consolidated Statements of Changes in Stockholders' Equity/Member's Equity are presented as of September 30, 2022 and 2021. In June 2021, the DT Midstream Board of Directors authorized the issuance of an additional 96,731,466 common shares in anticipation of the Separation, for a total of 96,732,466 common shares issued and outstanding. DT Midstream is authorized to issue 50,000,000 shares of preferred stock at $0.01 par value. No preferred stock was issued or outstanding as of September 30, 2022.

On July 1, 2021, DTE Energy completed the Separation through the distribution of 96,732,466 shares of DT Midstream common stock to DTE Energy shareholders. Following the Separation on July 1, 2021, DT Midstream became an independent public company listed under the symbol "DTM" on the NYSE. DTE Energy did not retain ownership in DT Midstream.

Basis of Presentation

The Consolidated Financial Statements and Notes to Consolidated Financial Statements as of and for periods subsequent to July 1, 2021, the date of the Separation, reflect the consolidated financial position, results of operations and cash flows for DT Midstream as an independent company. Prior to the Separation, DT Midstream operated as a consolidated entity of DTE Energy and not as a standalone company. For the periods prior to the Separation, the Consolidated Financial Statements and Notes to Consolidated Financial Statements were prepared on a carve-out basis using the consolidated financial statements and accounting records of DTE Energy. The carve-out basis financial statements represent the historical financial position, results of operations, and cash flows of DT Midstream as they were historically managed in accordance with GAAP and reflect significant assumptions and allocations. The carve-out financial statements may not include all expenses that would have been incurred had DT Midstream existed as a standalone entity. Certain prior-period amounts have been reclassified to conform to current-year presentation.

GAAP requires 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 DT Midstream’s estimates. DT Midstream believes the assumptions underlying these financial statements are reasonable.

Notes to Consolidated Financial Statements 

(Unaudited)

In DT Midstream's 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 September 30, 2022, results of operations for the three and nine months ended September 30, 2022 and 2021, statement of changes in stockholders' equity/member's equity for the three and nine months ended September 30, 2022 and 2021 and cash flows for the nine months ended September 30, 2022 and 2021. The balance sheet as of December 31, 2021 was derived from audited annual financial statements, but does not contain all of the footnote disclosures from the annual financial statements. 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, 2022. The Consolidated Financial Statements should be read in conjunction with the DT Midstream Consolidated Financial Statements and Notes to Consolidated Financial Statements included in DT Midstream's 2021 Annual Report on Form 10-K.

Cost Allocations

Prior to the Separation, DT Midstream received monthly allocations of general corporate expenses from DTE Energy which were classified within the appropriate Consolidated Statements of Operations line item. Operation and maintenance for the three and nine months ended September 30, 2021 included approximately $1 million and $20 million, respectively, of Separation related transaction costs for legal, accounting, auditing and other professional services. Effective July 1, 2021, with the completion of the Separation, DT Midstream no longer received corporate allocations from DTE Energy.

Corporate allocation amounts from DTE Energy were as follows:

	Three Months Ended		Nine Months Ended
	September 30,
	2021			2021
	(millions)
Operation and maintenance	$	—		$	32
Total DTE Energy corporate allocations	$	—		$	32

Cash Management

DT Midstream's sources of liquidity include cash generated from operations and available borrowings under our Revolving Credit Facility. DT Midstream began investing in money market cash equivalents in August 2021.

Prior to the Separation, DT Midstream’s sources of liquidity included cash generated from operations and loans obtained through DTE Energy’s corporate-wide cash management program, including a working capital loan agreement. Cash was managed centrally, with certain net earnings reinvested in, and working capital requirements met from, existing liquid funds. Effective July 1, 2021, DT Midstream no longer participated in the cash management program and the working capital loan was terminated.

Principles of Consolidation

DT Midstream consolidates all majority-owned subsidiaries and investments in entities in which we have a controlling influence. Non-majority owned investments are accounted for using the equity method of accounting when DT Midstream is able to significantly influence the operating policies of the investee. When DT Midstream does 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. DT Midstream eliminates all intercompany balances and transactions.

DT Midstream evaluates whether an entity is a VIE whenever reconsideration events occur. DT Midstream consolidates VIEs for which we are the primary beneficiary. If DT Midstream is not the primary beneficiary and an ownership interest is held, the VIE is accounted for under the equity method of accounting. When assessing the determination of the primary beneficiary, DT Midstream considers 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. DT Midstream performs ongoing reassessments of all VIEs to determine if the primary beneficiary status has changed.

The maximum risk exposure for consolidated VIEs is reflected on DT Midstream’s Consolidated Statements of Financial Position. For non-consolidated VIEs, the maximum risk exposure of DT Midstream is generally limited to its investment, notes receivable, future funding commitments, and amounts which it has guaranteed.

DT Midstream owns an 85% interest in the Stonewall Gas Gathering VIE and is the primary beneficiary, therefore Stonewall Gas Gathering is consolidated. Stonewall Gas Gathering has contracts in which certain construction risk was designed to pass-through to customers, with DT Midstream retaining operational and customer default risk. DT Midstream owns a 50% interest in the South Romeo VIE and is the primary beneficiary, therefore South Romeo is consolidated.

The following table summarizes the major line items in the Consolidated Statements of Financial Position for consolidated VIEs as of September 30, 2022 and December 31, 2021. All assets and liabilities of a consolidated VIE are presented where 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.

Amounts for consolidated VIEs are as follows:

	September 30,		December 31,

Equity Method Investments

Investments in non-consolidated affiliates that are not controlled by DT Midstream, but over which we have significant influence, are accounted for using the equity method of accounting. Under the equity method, investments are recorded at historical cost as an asset and adjusted for capital contributions, dividends and distributions received, and the Company's share of the investee's earnings or losses, which are recorded as earnings from equity method investees on the Consolidated Statements of Operations. DT Midstream's equity method investments are periodically evaluated for certain factors that may be indicative of other-than-temporary impairment. As of September 30, 2022 and December 31, 2021, DT Midstream’s carrying amounts of investments in equity method investees exceeded our share of the underlying equity in the net assets of the investees by $29 million and $32 million, respectively. The difference will be amortized over the life of the underlying assets. As of September 30, 2022 and December 31, 2021, DT Midstream's consolidated retained earnings balance includes undistributed earnings from equity method investments of $70 million and $84 million, respectively.

Equity method investees are described below:

	Investments As of				% Owned As of
	September 30,		December 31,		September 30,	December 31,

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.

DT Midstream regularly monitors the credit quality of its financing receivables by reviewing counterparty credit quality indicators and monitoring for triggering events, such as a credit rating downgrade or bankruptcy. DT Midstream has 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 September 30, 2022. As of September 30, 2022, the Notes receivable — related party of $4 million, which originated prior to 2021, was classified as internal grade 1.

Notes receivable are typically considered delinquent (past due) when payment is not received for periods ranging from 60 to 120 days. DT Midstream ceases accruing interest income (nonaccrual status) and may either write off or establish an allowance for expected credit loss for the note receivable when it is expected that all principal or interest amounts due will not be collected in accordance with the note's contractual terms. In determining an allowance for expected credit losses for or the write off of notes receivable, DT Midstream considers the historical payment experience and other factors that are expected to have a specific impact on collection, including existing and future economic conditions.

Cash receipts for notes receivable on nonaccrual status that do not bring the account contractually current are first applied to contractually owed past due interest, with any remainder applied to principal. Recognition of interest income is generally resumed when the note receivable becomes contractually current.

DT Midstream had an investment in certain assets in the Utica shale region which was accounted for as a Note receivable — third party. In the second quarter 2021, we assessed the note receivable for expected loss and recorded a $19 million loss on the note receivable to Asset (gains) losses and impairments, net on the Consolidated Statement of Operations. Additionally, DT Midstream ceased accruing interest on the note receivable balance and reclassified the note to an Internal grade 3 receivable. Subsequently, as cash payments were received, a portion was recognized as interest income. A third party purchased our investment in certain assets in the Utica shale region based on significantly improved commodity pricing during the second quarter 2022 for proceeds of $22 million. This resulted in a gain of $17 million recorded in Asset (gains) losses and impairments, net on the Consolidated Statement of Operations. DT Midstream maintains no continuing involvement with the note receivable.

There are no notes receivable on nonaccrual status and no past due financing receivables as of September 30, 2022.

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 specific circumstances of the associated receivable. Uncollectible expense (recovery) was zero for the three and nine months ended September 30, 2022 and 2021.

There is no allowance for expected credit loss related to Notes Receivable or Accounts Receivable as of September 30, 2022 or December 31, 2021.

NOTE 3 — NEW ACCOUNTING PRONOUNCEMENTS

Recently Adopted Pronouncements

In March 2020, the FASB issued ASU No. 2020-04, Reference Rate Reform (Topic 848) - Facilitation of the Effects of Reference Rate Reform on Financial Reporting, as amended. Subsequently, in January 2021, the FASB issued ASU No. 2021-01, Reference Rate Reform (Topic 848) - Scope, as amended. The amendments in these updates provide optional expedients and exceptions for applying GAAP to contract modifications and hedging relationships, subject to meeting certain criteria, that reference LIBOR or another reference rate expected to be discontinued. The guidance can be applied prospectively from any date beginning March 12, 2020 through December 31, 2022. The optional relief is temporary and cannot be applied to contract modifications and hedging relationships entered into or evaluated after December 31, 2022. DT Midstream adopted this standard which did not have a material impact on our Consolidated Financial Statements.

NOTE 4 — REVENUE

Significant Accounting Policy

Revenue is measured based upon the consideration specified in a contract with a customer at the time when performance obligations are satisfied. A performance obligation is a promise in a contract to transfer a distinct good or service or a series of distinct goods or services to the customer. Pipeline revenues consist of services related to the gathering, transportation and/or storage of natural gas. Gathering revenues consist of services related to the gathering, processing, and/or treating of natural gas. Pricing for such services may consist of demand rates, usage rates and other associated fees. Certain of our Gathering contracts allow for the recovery of production-related operating expenses, which are recorded as revenue. Revenue is recognized when performance obligations are satisfied by transferring control over a service to a customer, which occurs when the service is provided to the customer. When a customer simultaneously receives and consumes the product or service provided, revenue is recognized over time. Alternatively, if it is determined that the criteria for recognition of revenue over time is not met, the revenue is considered to be recognized at a point in time.

DT Midstream primarily provides two types of revenue services: firm service and interruptible service. Firm service revenue contracts are typically long-term and structured using fixed demand charges or minimum volume commitments with fixed deficiency fee rates. This provides 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. Interruptible service revenue contracts contain fixed usage rates, with total consideration dependent on actual natural gas volumes that flow.

Disaggregation of Revenue

The following is a summary of revenues disaggregated by segment:

	Three Months Ended				Nine Months Ended

The contract liabilities at DT Midstream generally represent amounts paid by or receivable from customers for which the associated performance obligation has not yet been satisfied. Performance obligations associated with contract liabilities include providing services related to customer prepayments. Contract liabilities associated with these services are recognized when control has transferred to the customer.

Transaction Price Allocated to the Remaining Performance Obligations

In accordance with optional exemptions available under Topic 606, DT Midstream does 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 DT Midstream's invoices for actual goods provided and services performed, and (3) contracts for which variable consideration relates entirely to an unsatisfied performance obligation.

Such contracts consist of various types of performance obligations, including the delivery of 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 consideration under the contract 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 September 30, 2022 that are expected to be recognized as revenue in future periods:

NOTE 5 — 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. Restricted stock units and performance shares, 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 shares do not receive cash dividends, as such, these awards are not considered participating securities.

DT Midstream issued 1,000 shares of common stock at $0.01 par value to its parent, a subsidiary of DTE Energy, in January 2021. The DT Midstream Board of Directors authorized the issuance of an additional 96,731,466 common shares on June 30, 2021 for a total of 96,732,466 common shares issued and outstanding at the Separation date. This share amount is treated as issued and outstanding and utilized for the calculation of historical basic and diluted earnings per share for all periods prior to the Separation.

The following is a reconciliation of DT Midstream's basic and diluted earnings per share calculation:

NOTE 6 — INCOME TAXES

Effective Tax Rates

DT Midstream records income taxes during the interim period using an estimated annual effective tax rate ("ETR") and recognizes specific events discretely as they occur.

The interim ETRs of DT Midstream are 6% and 27% for the three months ended September 30, 2022 and 2021, respectively, and 18% and 26% for the nine months ended September 30, 2022 and 2021, respectively. The difference between the interim ETR and federal statutory rate of 21% is primarily related to state income taxes. The decrease in the interim ETRs for the three and nine month comparative periods is primarily driven by the remeasurement of state deferred taxes in 2022, as described below.

Tax Legislation

On July 8, 2022, the Commonwealth of Pennsylvania enacted House Bill (H.B.) 1342 which includes a corporate income tax rate reduction from 9.99% to 4.99% that will phase-in over a nine-year period. As a corporate taxpayer in Pennsylvania and in accordance with tax accounting guidance, we recorded the $25 million impact of remeasuring our deferred tax balances to continuing operations (tax expense) in the three months ended September 30, 2022. The impact of the rate change resulted in a 20% and 7% decrease to the effective tax rate for the three and nine months ended September 30, 2022.

On August 16, 2022, President Biden signed H.R. 5374 (Inflation Reduction Act) into law. The bill includes a number of tax, health care, and energy-related provisions. We will continue to evaluate the tax provisions of the bill, but do not anticipate the bill to have a material impact on our consolidated financial statements.

NOTE 7 — 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. DT Midstream makes certain assumptions it believes that market participants would use in pricing assets or liabilities, including assumptions about risk, and the risks inherent in the inputs to valuation techniques. DT Midstream believes it uses 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. DT Midstream classifies 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 DT Midstream has 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.

NOTE 8 — DEBT

Credit Agreement

As of September 30, 2022, DT Midstream's Credit Agreement provided for a 7-year term loan facility and a $750 million 5-year secured revolving credit facility. On October 19, 2022, DT Midstream amended the Credit Agreement to increase the Revolving Credit Facility commitments by $250 million to aggregate commitments of $1.0 billion and to extend the maturity date to October 19, 2027. See Note 11, "Subsequent Events" to the Consolidated Financial Statements.

Debt Issuances

On June 9, 2021, DT Midstream issued senior unsecured notes of $1.1 billion in aggregate principal amount due June 15, 2029 (the "2029 Notes") and $1.0 billion in aggregate principal amount due June 15, 2031 (the "2031 Notes").

In April 2022, DT Midstream issued $600 million in aggregate principal amount of 4.300% senior secured notes due April 2032 (the "2032 Notes"). The 2032 Notes are guaranteed by certain of DT Midstream's subsidiaries and secured by a first priority lien on certain assets of DT Midstream and its subsidiary guarantors that secure DT Midstream's existing credit facilities. The 2032 Notes have a security fall away provision where the collateral securing the notes will be released if DT Midstream receives an investment-grade rating from two of the three credit rating agencies. As part of the issuance of the 2032 Notes, DT Midstream's capitalized debt issuance and discount costs are approximately $4 million and $1 million, respectively.

Debt Redemptions

DT Midstream used $593 million of the net proceeds from the sale of the 2032 Notes to make a partial repayment on our existing indebtedness under our Term Loan Facility. As a result, required quarterly principal payments were eliminated, and the remaining Term Loan Facility balance is not due until maturity in 2028. There were no prepayment costs in conjunction with the partial redemption of the Term Loan Facility. The early redemption resulted in a loss on extinguishment of debt of $9 million and loss on modification of debt of $4 million relating to the write-off of unamortized discount and issuance costs, which was recorded as a loss from financing activities on DT Midstream’s Consolidated Statements of Operations for the nine months ended September 30, 2022.

Borrowings under the Revolving Credit Facility are used for general corporate purposes, acquisitions including our Millennium Pipeline acquisition, and letter of credit issuances to support DT Midstream's future operations and liquidity.

The Credit Agreement covering the Term Loan Facility and Revolving Credit Facility includes financial covenants that DT Midstream must maintain. These covenants restrict the ability of DT Midstream and its 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 its 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. At September 30, 2022, the debt service coverage ratio, the consolidated net leverage ratio and the interest coverage ratio was 7.1 to 1, 3.4 to 1 and 6.2 to 1, respectively, and DT Midstream was in compliance with these financial covenants.

NOTE 9 — COMMITMENTS AND CONTINGENCIES

From time to time, DT Midstream is 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. DT Midstream cannot predict the final disposition of such proceedings. DT Midstream regularly reviews legal matters and records 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 DT Midstream’s business, financial condition and results of operations.

Guarantees

In certain limited circumstances, DT Midstream enters into contractual guarantees. DT Midstream may guarantee another entity's obligation in the event it fails to perform and may provide guarantees in certain indemnification agreements. DT Midstream did not have any guarantees of other parties' obligations as of September 30, 2022.

Vector Pipeline Line of Credit

DT Midstream is the lender under a revolving term credit facility to Vector Pipeline, 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 Pipeline may only draw upon the facility if the funds are required to respond to a catastrophic event. The maximum potential payout at September 30, 2022 is USD $51 million. The funding of a loan under the terms of the credit facility is considered remote.

Environmental Contingencies

In order to comply with certain state environmental regulations, DT Midstream has an obligation to restore pipeline right-of-way slope failures that may arise in the ordinary course of business in the Utica and Marcellus shale region. Slope restoration expenditures are typically capital in nature. As of September 30, 2022 and December 31, 2021, DT Midstream had accrued contingent liabilities of $20 million for future slope restoration expenditures. The accrual is included in Other current liabilities and Other liabilities in the Consolidated Statements of Financial Position. DT Midstream believes the accrued amounts are sufficient to cover estimated future expenditures.

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 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 2021 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 lateral pipelines, and through our Gathering segment. We also own joint venture interests in equity method investees which own and operate interstate pipelines, which have connectivity to our wholly owned assets.

Our core assets strategically connect key demand centers in the Midwestern U.S., Eastern Canada, Northeastern U.S. and Gulf Coast regions to production areas of the Haynesville and Marcellus/Utica dry natural gas formations in the Gulf Coast and Appalachian Basins, respectively.

On July 1, 2021, DT Midstream completed the Separation from DTE Energy and became an independent public company. See Note 1, "Description of the Business and Basis of Presentation" to the Consolidated Financial Statements under Part I, Item 1 of this Form 10-Q.

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 greenhouse gas reducing technologies as part of our goal of being leading environmental stewards in the midstream industry and have announced a net zero carbon emissions goal by 2050. Our strategy is premised on the following principles:

•disciplined capital deployment in assets supported by strong fundamentals;

•capitalize on asset integration and utilization opportunities;

•pursue economically attractive opportunities;

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

•provide exceptional service to our customers.

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.

In November 2020, the SEC issued a final rule to modernize and simplify Management's Discussion and Analysis and certain financial disclosure requirements in SEC Regulation S-K. As permitted by this final rule, the analysis below reflects the optional approach to discuss results of operations on a sequential-quarter basis, which we believe will provide the most useful information to investors in assessing our quarterly results of operations going forward. In addition, as required by the final rule, we have continued to provide a comparison of the current year-to-date period to the prior year-to-date period.

For purposes of the following discussion, any increases or decreases refer to the comparison of the three months ended September 30, 2022 to the three months ended June 30, 2022, and the nine months ended September 30, 2022 to the nine months ended September 30, 2021, as applicable.

The following table summarizes our consolidated financial results:

	Three Months Ended				Nine Months Ended

Operating revenues increased $4 million for the three months ended September 30, 2022 primarily due to a new long-term storage contract at the Washington 10 Storage Complex and higher rates on LEAP. Operating revenues increased $20 million for the nine months ended September 30, 2022 primarily due to higher volumes and rates on LEAP of $18 million and a new customer on Stonewall Gas Gathering of $3 million.

Operation and maintenance expense decreased $7 million for the nine months ended September 30, 2022 primarily due to lower Separation related transaction costs of $10 million, partially offset by increased Washington 10 Storage Complex expenses.

Asset (gains) losses and impairments, net decreased $6 million for the three months ended September 30, 2022 and increased $6 million for the nine months ended September 30, 2022 due to a one-time gain realized from a legal settlement with a supplier that occurred during the three months ended June 30, 2022.

Interest expense increased $4 million for the nine months ended September 30, 2022 primarily due to higher interest rates on our external debt as compared to interest rates on borrowings from DTE Energy prior to the Separation.

Earnings from equity method investees increased $17 million for the nine months ended September 30, 2022 primarily due to higher revenues from increased contract rates and additional customers at NEXUS of $13 million and higher westbound contracted volumes at Vector Pipeline of $3 million.

Loss from financing activities decreased $6 million for the three months ended September 30, 2022 and increased $6 million for the nine months ended September 30, 2022 due to the partial repayment of our Term Loan Facility that occurred during the three months ended June 30, 2022. See Note 8, "Debt" to the Consolidated Financial Statements under Part I, Item 1 of this Form 10-Q for further details.

Income tax expense decreased $14 million and $7 million for the three and nine months ended September 30, 2022, respectively, primarily due to a decrease in Pennsylvania income tax rates which resulted in a $15 million benefit from remeasuring our deferred tax balances. The decrease for the nine months ended September 30, 2022 was partially offset by an increase in Income before income taxes. See Note 6, "Income Taxes" to the Consolidated Financial Statements under Part I, Item 1 of this Form 10-Q for further details.

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 future Haynesville System expansion (LEAP) and additional growth related to our equity method investments. On October 7, 2022, DT Midstream closed on the $552 million purchase of an additional 26.25% ownership interest in Millennium Pipeline from National Grid. See Note 11, "Subsequent Events" to the Consolidated Financial Statements under Part I, Item 1 of this Form 10-Q.

Gathering

The Gathering segment consists of our gathering systems including related treatment plants and compression and surface facilities. Gathering results and outlook are discussed below:

	Three Months Ended				Nine Months Ended

Income Tax Expense	2		14		25		32
Net Income Attributable to DT Midstream	$	43	$	39	$	115	$	93

Operating revenues increased $4 million for the three months ended September 30, 2022 due to higher volumes on Blue Union and Susquehanna Gathering System. Operating revenues increased $40 million for the nine months ended September 30, 2022 primarily due to higher Blue Union revenues of $36 million and higher compression revenue on Susquehanna Gathering System. Higher Blue Union revenues were driven by recovery of production-related operating expenses of $22 million and increased gathering volumes of $14 million.

Operation and maintenance expense increased $31 million for the nine months ended September 30, 2022 primarily due to higher Blue Union and Susquehanna Gathering System expenses of $36 million and $2 million, respectively, partially offset by lower Appalachia Gathering System expenses of $7 million. Higher Blue Union expenses were driven by increased production-related operating expenses and planned maintenance. Higher public company costs were mostly offset by lower Separation related transaction costs of $10 million.

Depreciation and amortization expense increased $3 million for the nine months ended September 30, 2022 primarily due to additional depreciation and amortization expense related to new Blue Union and Susquehanna Gathering System assets placed into service.

Asset (gains) losses and impairments, net decreased $17 million for the three months ended September 30, 2022 due to a one-time gain on sale of certain assets in the Utica shale region that occurred during the three months ended June 30, 2022. Asset (gains) losses and impairments, net increased $34 million for the nine months ended September 30, 2022. The increase was due to the 2022 gain of $17 million mentioned above as compared to the 2021 loss on notes receivable for an investment in certain assets in the Utica shale region of $19 million, partially offset by a $2 million gain on sale of Michigan gathering assets. See Note 2, "Significant Accounting Policies" to the Consolidated Financial Statements under Part I, Item 1 of this Form 10-Q for further details.

Interest expense increased $14 million for the nine months ended September 30, 2022 primarily due to higher outstanding borrowings and higher interest rates on our external debt as compared to interest rates on borrowings from DTE Energy prior to the Separation.

28

Loss from financing activities decreased $7 million for the three months ended September 30, 2022 and increased $7 million for the nine months ended September 30, 2022 due to the partial repayment of our Term Loan Facility that occurred during the three months ended June 30, 2022. See Note 8, "Debt" to the Consolidated Financial Statements under Part I, Item 1 of this Form 10-Q for further details.

Income tax expense decreased $12 million and $7 million for the three and nine months ended September 30, 2022, respectively, primarily due to a decrease in Pennsylvania income tax rates which resulted in a $10 million benefit from remeasuring our deferred tax balances. The decrease for the nine months ended September 30, 2022 was partially offset by an increase in Income before income taxes. See Note 6, "Income Taxes" to the Consolidated Financial Statements under Part I, Item 1 of this Form 10-Q for further details.

Gathering Outlook

We believe our long-term agreements with producers and the quality of the natural gas reserves in the Marcellus/Utica and Haynesville shale regions 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 Haynesville System expansion (Blue Union) and expansion opportunities at the Appalachia Gathering System.

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 contributions to equity method investees, were $177 million for the nine months ended September 30, 2022. On October 7, 2022, DT Midstream closed on the $552 million purchase of an additional 26.25% ownership interest in Millennium Pipeline from National Grid. See Note 11, "Subsequent Events" to the Consolidated Financial Statements under Part I, Item 1 of this Form 10-Q. We anticipate total capital expenditures, inclusive of contributions to equity method investees and the Millennium Pipeline acquisition discussed above, in 2022 of approximately $860 million to $910 million.

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 9, "Commitments and Contingencies" to the Consolidated Financial Statements under Part I, Item 1 of this Form 10-Q.

29

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. We expect that cash from operating activities in 2022 will be approximately $605 million to $655 million.

	Nine Months Ended
	September 30,
	2022		2021
	(millions)
Cash and Cash Equivalents at Beginning of Period	$	132	$	42
Net cash and cash equivalents from operating activities	574		464
Net cash and cash equivalents (used for) from investing activities	(150)		163
Net cash and cash equivalents used for financing activities	(201)		(541)
Net Increase in Cash and Cash Equivalents	223		86
Cash and Cash Equivalents at End of Period	$	355	$	128

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 commodity 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 $110 million for the nine months ended September 30, 2022 primarily due to net changes in working capital, an increase in operating income after adjustment for non-cash items including depreciation and amortization expense, amortization of operating lease right-of-use assets, and assets (gains) losses and impairments, and an increase in dividends received from equity method investees. These increases were partially offset by an increase in interest expense and an increase in cash paid for income taxes.

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 from investing activities decreased $313 million to represent net cash and cash equivalents used for investing activities for the nine months ended September 30, 2022, primarily due to the 2021 cash collection of the Notes receivable from DTE Energy and an increase in plant and equipment expenditures in 2022, partially offset by proceeds from the sale of notes receivable in 2022.

Financing Activities

Prior to the Separation, we relied on short-term borrowings and contributions from DTE Energy. In June 2021, we issued the 2029 Notes and 2031 Notes in aggregate principal amount of $2.1 billion and entered into a $1.0 billion Term Loan Facility. Proceeds were used for the repayment of the short-term borrowings due to DTE Energy as well as a one-time special dividend provided to DTE Energy.

In April 2022, we issued the 2032 Notes in aggregate principal amount of $600 million. We used the net proceeds from the sale of the 2032 Notes of $593 million to partially repay indebtedness under our Term Loan Facility. See Note 8, "Debt" to the Consolidated Financial Statements under Part I, Item 1 of this Form 10-Q.

30

Net cash and cash equivalents used for financing activities decreased $340 million for the nine months ended September 30, 2022 primarily due to the 2021 Separation-related repayment of short-term borrowings and special dividend to DTE Energy, partially offset by contributions from DTE Energy that did not recur in 2022. Additionally, the decrease was partially offset by lower proceeds from the issuance of long-term debt, higher repayment of long-term debt, and higher dividends paid on common stock in 2022.

During the nine months ended September 30, 2022, DT Midstream paid cash dividends on common stock. See Note 5, "Earnings per Share and Dividends" to the Consolidated Financial Statements under Part I, Item 1 of this Form 10-Q.

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 additional long-term firm service revenue contracts from customers.

Our sources of liquidity include cash generated from operating activities and available borrowings under our Revolving Credit Facility. In June 2021, we issued the 2029 Notes and 2031 Notes in aggregate principal amount of $2.1 billion and entered into a $1.0 billion Term Loan Facility. We also entered into a $750 million secured Revolving Credit Facility for general corporate purposes and letter of credit issuances to support our future operations and liquidity. In April 2022, we issued the 2032 Notes in an aggregate principal amount of $600 million. We used the net proceeds from the sale of the Senior Secured Notes of $593 million to partially repay indebtedness under our Term Loan Facility.

As of September 30, 2022, we had $31 million of letters of credit outstanding and no borrowings outstanding under our Revolving Credit Facility. We had approximately $1.1 billion of available liquidity as of September 30, 2022, consisting of cash and cash equivalents and amounts available under our Revolving Credit Facility.

In October 2022, DT Midstream closed on the $552 million purchase of an additional 26.25% ownership interest in Millennium Pipeline from National Grid. Additionally, we amended the Credit Agreement to increase the Revolving Credit Facility commitments by $250 million to aggregate commitments of $1.0 billion and extended the maturity to October 19, 2027. See Note 11, "Subsequent Events" to the Consolidated Financial Statements under Part I, Item 1 of this Form 10-Q for additional discussion on the Millennium Pipeline acquisition and the amendment to the Credit Agreement. The Credit Agreement covering the Term Loan Facility and Revolving Credit Facility includes financial covenants that DT Midstream must maintain. See Note 8, "Debt" to the Consolidated Financial Statements under Part I, Item 1 of this Form 10-Q for additional discussion on the financial covenants.

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 consistent with cash flow growth and are targeting a payout ratio consistent with pure-play midstream companies.

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

See Note 1, "Description of the Business and Basis of Presentation", Note 8, "Debt" and Note 9, "Commitments and Contingencies" to the Consolidated Financial Statements under Part I, Item 1 of this Form 10-Q.

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. An impairment test for goodwill is performed annually as of October 1st, or whenever events or circumstances indicate that the value of goodwill may be impaired. In between annual impairment tests, we monitor our estimates and assumptions regarding estimated future cash flows, including the impact of movements in market indicators in future quarters, and will update the impairment analyses if a triggering event occurs. While we believe the assumptions are reasonable, 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.

We have noted an increase in our weighted average cost of capital resulting from interest rate increases since our last annual goodwill impairment test. We have determined that an interim impairment test is not required as there are no triggering events or changes in circumstances indicating that it is more likely than not that the goodwill for either of our two reporting units is impaired. We will continue to monitor our estimates and assumptions on a quarterly basis as market conditions continue to evolve.

See Part I, Item 3, "Quantitative and Qualitative Disclosures About Market Risk", in this Quarterly Report for more information on our exposure to market risk. See also "Critical Accounting Estimates" included in DT Midstream's 2021 Annual Report on Form 10-K.

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 areas of operation. Low prices for natural gas, including those resulting from regional basis differentials, could adversely affect development of additional reserves and future production that is accessible by our pipeline and storage assets. We manage our exposure through the use of short, medium, and long-term storage, gathering, and transportation contracts. Consequently, our existing operations and cash flows have limited direct exposure to commodity 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 system expansions, we have entered into negotiated credit agreements that provide for enhanced forms of credit support if certain credit standards are not met.

We depend on key customers in the Haynesville shale formation in the Gulf Coast and in the Utica and Marcellus shale formations in the Northeastern U.S. for a significant portion of our revenues. The loss of, or reduction in volumes from, any of these key customers 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 two of our key customers, Southwestern Energy and Antero Resources. 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 have no bankruptcy proceedings during the three and nine months ended September 30, 2022.

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 LIBOR and SOFR. As of September 30, 2022, we had floating rate debt of $399 million and a floating rate debt-to-total debt ratio of 13% related to the variable rate Term Loan Facility entered into June 2021. See Note 8, "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 the section entitled "Critical Accounting Estimates" for more information.

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 rates at September 30, 2022 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:

	Assuming a 10% Increase in Rates		Assuming a 10% Decrease in Rates		Change in the Fair Value of
Activity	As of September 30, 2022
	(millions)
Interest rate risk	$	(105)	$	111	Long-term debt

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 September 30, 2022, which is the end of the period covered by this report. Based on this evaluation, DT Midstream's CEO and CFO have concluded that such disclosure controls and procedures are effective in providing reasonable assurance that information required to be disclosed by DT Midstream in reports that it files or submits under the Exchange Act (i) is recorded, processed, summarized, and reported within the time periods specified in the SEC's rules and forms and (ii) is accumulated and communicated to DT Midstream's management, including its CEO and CFO, as appropriate to allow timely decisions regarding required disclosure. Due to the inherent limitations in the effectiveness of any disclosure controls and procedures, management cannot provide absolute assurance that the objectives of its disclosure controls and procedures will be attained.

(b) Changes in internal control over financial reporting

There have been no changes in DT Midstream's internal control over financial reporting during the quarter ended September 30, 2022 that have materially affected, or are reasonably likely to materially affect, DT Midstream's internal control over financial reporting.

Description of the Business and Basis of Presentation

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. The Company provides multiple, integrated natural gas services to customers through two segments: (i) Pipeline, which includes interstate pipelines, intrastate pipelines, storage systems, lateral pipelines and related treatment plants and compression and surface facilities, and (ii) Gathering, which includes gathering systems and related treatment plants, and compression and surface facilities. DT Midstream's Pipeline segment also includes interests in equity method investees which own and operate interstate pipelines, which have connectivity to DT Midstream’s assets.

DT Midstream’s core assets connect demand centers in the Midwestern U.S., Eastern Canada, Northeastern U.S. and Gulf Coast regions to production areas of the Haynesville and Marcellus/Utica dry natural gas formations in the Gulf Coast and Appalachian Basins, respectively.

In connection with the Separation from DTE Energy, on January 13, 2021, DTE Gas Enterprises, LLC, and its consolidated subsidiaries converted into a Delaware corporation pursuant to a statutory conversion and changed its name to DT Midstream, Inc. ("DT Midstream"). At the conversion, DT Midstream issued 1,000 shares of common stock at $0.01 par value to its parent, a subsidiary of DTE Energy. As DT Midstream was a single member LLC as of December 31, 2020, and a corporation with stockholders' equity as of September 30, 2022 and 2021, Consolidated Statements of Changes in Stockholders' Equity/Member's Equity are presented as of September 30, 2022 and 2021. In June 2021, the DT Midstream Board of Directors authorized the issuance of an additional 96,731,466 common shares in anticipation of the Separation, for a total of 96,732,466 common shares issued and outstanding. DT Midstream is authorized to issue 50,000,000 shares of preferred stock at $0.01 par value. No preferred stock was issued or outstanding as of September 30, 2022.

On July 1, 2021, DTE Energy completed the Separation through the distribution of 96,732,466 shares of DT Midstream common stock to DTE Energy shareholders. Following the Separation on July 1, 2021, DT Midstream became an independent public company listed under the symbol "DTM" on the NYSE. DTE Energy did not retain ownership in DT Midstream.

Basis of Presentation

The Consolidated Financial Statements and Notes to Consolidated Financial Statements as of and for periods subsequent to July 1, 2021, the date of the Separation, reflect the consolidated financial position, results of operations and cash flows for DT Midstream as an independent company. Prior to the Separation, DT Midstream operated as a consolidated entity of DTE Energy and not as a standalone company. For the periods prior to the Separation, the Consolidated Financial Statements and Notes to Consolidated Financial Statements were prepared on a carve-out basis using the consolidated financial statements and accounting records of DTE Energy. The carve-out basis financial statements represent the historical financial position, results of operations, and cash flows of DT Midstream as they were historically managed in accordance with GAAP and reflect significant assumptions and allocations. The carve-out financial statements may not include all expenses that would have been incurred had DT Midstream existed as a standalone entity. Certain prior-period amounts have been reclassified to conform to current-year presentation.

GAAP requires 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 DT Midstream’s estimates. DT Midstream believes the assumptions underlying these financial statements are reasonable.

In DT Midstream's 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 September 30, 2022, results of operations for the three and nine months ended September 30, 2022 and 2021, statement of changes in stockholders' equity/member's equity for the three and nine months ended September 30, 2022 and 2021 and cash flows for the nine months ended September 30, 2022 and 2021. The balance sheet as of December 31, 2021 was derived from audited annual financial statements, but does not contain all of the footnote disclosures from the annual financial statements. 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, 2022. The Consolidated Financial Statements should be read in conjunction with the DT Midstream Consolidated Financial Statements and Notes to Consolidated Financial Statements included in DT Midstream's 2021 Annual Report on Form 10-K.

Cost Allocations

Prior to the Separation, DT Midstream received monthly allocations of general corporate expenses from DTE Energy which were classified within the appropriate Consolidated Statements of Operations line item. Operation and maintenance for the three and nine months ended September 30, 2021 included approximately $1 million and $20 million, respectively, of Separation related transaction costs for legal, accounting, auditing and other professional services. Effective July 1, 2021, with the completion of the Separation, DT Midstream no longer received corporate allocations from DTE Energy.

Corporate allocation amounts from DTE Energy were as follows:

	Three Months Ended		Nine Months Ended
	September 30,
	2021			2021
	(millions)
Operation and maintenance	$	—		$	32
Total DTE Energy corporate allocations	$	—		$	32

Cash Management

DT Midstream's sources of liquidity include cash generated from operations and available borrowings under our Revolving Credit Facility. DT Midstream began investing in money market cash equivalents in August 2021.

Prior to the Separation, DT Midstream’s sources of liquidity included cash generated from operations and loans obtained through DTE Energy’s corporate-wide cash management program, including a working capital loan agreement. Cash was managed centrally, with certain net earnings reinvested in, and working capital requirements met from, existing liquid funds. Effective July 1, 2021, DT Midstream no longer participated in the cash management program and the working capital loan was terminated.

Principles of Consolidation

DT Midstream consolidates all majority-owned subsidiaries and investments in entities in which we have a controlling influence. Non-majority owned investments are accounted for using the equity method of accounting when DT Midstream is able to significantly influence the operating policies of the investee. When DT Midstream does 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. DT Midstream eliminates all intercompany balances and transactions.

DT Midstream evaluates whether an entity is a VIE whenever reconsideration events occur. DT Midstream consolidates VIEs for which we are the primary beneficiary. If DT Midstream is not the primary beneficiary and an ownership interest is held, the VIE is accounted for under the equity method of accounting. When assessing the determination of the primary beneficiary, DT Midstream considers 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. DT Midstream performs ongoing reassessments of all VIEs to determine if the primary beneficiary status has changed.

The maximum risk exposure for consolidated VIEs is reflected on DT Midstream’s Consolidated Statements of Financial Position. For non-consolidated VIEs, the maximum risk exposure of DT Midstream is generally limited to its investment, notes receivable, future funding commitments, and amounts which it has guaranteed.

DT Midstream owns an 85% interest in the Stonewall Gas Gathering VIE and is the primary beneficiary, therefore Stonewall Gas Gathering is consolidated. Stonewall Gas Gathering has contracts in which certain construction risk was designed to pass-through to customers, with DT Midstream retaining operational and customer default risk. DT Midstream owns a 50% interest in the South Romeo VIE and is the primary beneficiary, therefore South Romeo is consolidated.

The following table summarizes the major line items in the Consolidated Statements of Financial Position for consolidated VIEs as of September 30, 2022 and December 31, 2021. All assets and liabilities of a consolidated VIE are presented where 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.

Amounts for consolidated VIEs are as follows:

	September 30,		December 31,
	2022		2021
	(millions)
ASSETS (a)
Cash	$	22	$	23

(a)Amounts shown are 100% of the consolidated VIEs' assets and liabilities.

DT Midstream had a variable interest in an investment in certain assets in the Utica shale region that was accounted for as a Note receivable — third party. DT Midstream did not have an ownership interest in the entity and was not the primary beneficiary. This investment was sold during the second quarter 2022. See Note 2, "Significant Accounting Policies – Financing Receivables" to the Consolidated Financial Statements for additional discussion.

Related Parties

Transactions between DT Midstream and DTE Energy prior to the Separation, as well as all transactions between DT Midstream and its equity method investees, have been presented as related party transactions in the accompanying Consolidated Financial Statements.

Equity Method Investments

Investments in non-consolidated affiliates that are not controlled by DT Midstream, but over which we have significant influence, are accounted for using the equity method of accounting. Under the equity method, investments are recorded at historical cost as an asset and adjusted for capital contributions, dividends and distributions received, and the Company's share of the investee's earnings or losses, which are recorded as earnings from equity method investees on the Consolidated Statements of Operations. DT Midstream's equity method investments are periodically evaluated for certain factors that may be indicative of other-than-temporary impairment. As of September 30, 2022 and December 31, 2021, DT Midstream’s carrying amounts of investments in equity method investees exceeded our share of the underlying equity in the net assets of the investees by $29 million and $32 million, respectively. The difference will be amortized over the life of the underlying assets. As of September 30, 2022 and December 31, 2021, DT Midstream's consolidated retained earnings balance includes undistributed earnings from equity method investments of $70 million and $84 million, respectively.

Equity method investees are described below:

	Investments As of				% Owned As of
	September 30,		December 31,		September 30,	December 31,

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.

DT Midstream regularly monitors the credit quality of its financing receivables by reviewing counterparty credit quality indicators and monitoring for triggering events, such as a credit rating downgrade or bankruptcy. DT Midstream has 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 September 30, 2022. As of September 30, 2022, the Notes receivable — related party of $4 million, which originated prior to 2021, was classified as internal grade 1.

Notes receivable are typically considered delinquent (past due) when payment is not received for periods ranging from 60 to 120 days. DT Midstream ceases accruing interest income (nonaccrual status) and may either write off or establish an allowance for expected credit loss for the note receivable when it is expected that all principal or interest amounts due will not be collected in accordance with the note's contractual terms. In determining an allowance for expected credit losses for or the write off of notes receivable, DT Midstream considers the historical payment experience and other factors that are expected to have a specific impact on collection, including existing and future economic conditions.

Cash receipts for notes receivable on nonaccrual status that do not bring the account contractually current are first applied to contractually owed past due interest, with any remainder applied to principal. Recognition of interest income is generally resumed when the note receivable becomes contractually current.

DT Midstream had an investment in certain assets in the Utica shale region which was accounted for as a Note receivable — third party. In the second quarter 2021, we assessed the note receivable for expected loss and recorded a $19 million loss on the note receivable to Asset (gains) losses and impairments, net on the Consolidated Statement of Operations. Additionally, DT Midstream ceased accruing interest on the note receivable balance and reclassified the note to an Internal grade 3 receivable. Subsequently, as cash payments were received, a portion was recognized as interest income. A third party purchased our investment in certain assets in the Utica shale region based on significantly improved commodity pricing during the second quarter 2022 for proceeds of $22 million. This resulted in a gain of $17 million recorded in Asset (gains) losses and impairments, net on the Consolidated Statement of Operations. DT Midstream maintains no continuing involvement with the note receivable.

There are no notes receivable on nonaccrual status and no past due financing receivables as of September 30, 2022.

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 specific circumstances of the associated receivable. Uncollectible expense (recovery) was zero for the three and nine months ended September 30, 2022 and 2021.

There is no allowance for expected credit loss related to Notes Receivable or Accounts Receivable as of September 30, 2022 or December 31, 2021.

Revenue

Revenue from Contract with Customer [Abstract]

Revenue

REVENUE

Significant Accounting Policy

Revenue is measured based upon the consideration specified in a contract with a customer at the time when performance obligations are satisfied. A performance obligation is a promise in a contract to transfer a distinct good or service or a series of distinct goods or services to the customer. Pipeline revenues consist of services related to the gathering, transportation and/or storage of natural gas. Gathering revenues consist of services related to the gathering, processing, and/or treating of natural gas. Pricing for such services may consist of demand rates, usage rates and other associated fees. Certain of our Gathering contracts allow for the recovery of production-related operating expenses, which are recorded as revenue. Revenue is recognized when performance obligations are satisfied by transferring control over a service to a customer, which occurs when the service is provided to the customer. When a customer simultaneously receives and consumes the product or service provided, revenue is recognized over time. Alternatively, if it is determined that the criteria for recognition of revenue over time is not met, the revenue is considered to be recognized at a point in time.

DT Midstream primarily provides two types of revenue services: firm service and interruptible service. Firm service revenue contracts are typically long-term and structured using fixed demand charges or minimum volume commitments with fixed deficiency fee rates. This provides 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. Interruptible service revenue contracts contain fixed usage rates, with total consideration dependent on actual natural gas volumes that flow.

Disaggregation of Revenue

The following is a summary of revenues disaggregated by segment:

Balance at September 30	$	29

The contract liabilities at DT Midstream generally represent amounts paid by or receivable from customers for which the associated performance obligation has not yet been satisfied. Performance obligations associated with contract liabilities include providing services related to customer prepayments. Contract liabilities associated with these services are recognized when control has transferred to the customer.

The following table presents contract liability amounts as of September 30, 2022 that are expected to be recognized as revenue in future periods:

Transaction Price Allocated to the Remaining Performance Obligations

In accordance with optional exemptions available under Topic 606, DT Midstream does 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 DT Midstream's invoices for actual goods provided and services performed, and (3) contracts for which variable consideration relates entirely to an unsatisfied performance obligation.

Such contracts consist of various types of performance obligations, including the delivery of 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 consideration under the contract is variable at the contract inception. Contract lengths vary from cancellable to multi-year.

Earnings Per Share and Dividends

Earnings Per Share [Abstract]

Earnings Per Share and Dividends

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. Restricted stock units and performance shares, 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 shares do not receive cash dividends, as such, these awards are not considered participating securities.

DT Midstream issued 1,000 shares of common stock at $0.01 par value to its parent, a subsidiary of DTE Energy, in January 2021. The DT Midstream Board of Directors authorized the issuance of an additional 96,731,466 common shares on June 30, 2021 for a total of 96,732,466 common shares issued and outstanding at the Separation date. This share amount is treated as issued and outstanding and utilized for the calculation of historical basic and diluted earnings per share for all periods prior to the Separation.

The following is a reconciliation of DT Midstream's basic and diluted earnings per share calculation:

DT Midstream records income taxes during the interim period using an estimated annual effective tax rate ("ETR") and recognizes specific events discretely as they occur.

The interim ETRs of DT Midstream are 6% and 27% for the three months ended September 30, 2022 and 2021, respectively, and 18% and 26% for the nine months ended September 30, 2022 and 2021, respectively. The difference between the interim ETR and federal statutory rate of 21% is primarily related to state income taxes. The decrease in the interim ETRs for the three and nine month comparative periods is primarily driven by the remeasurement of state deferred taxes in 2022, as described below.

Tax Legislation

On July 8, 2022, the Commonwealth of Pennsylvania enacted House Bill (H.B.) 1342 which includes a corporate income tax rate reduction from 9.99% to 4.99% that will phase-in over a nine-year period. As a corporate taxpayer in Pennsylvania and in accordance with tax accounting guidance, we recorded the $25 million impact of remeasuring our deferred tax balances to continuing operations (tax expense) in the three months ended September 30, 2022. The impact of the rate change resulted in a 20% and 7% decrease to the effective tax rate for the three and nine months ended September 30, 2022.

On August 16, 2022, President Biden signed H.R. 5374 (Inflation Reduction Act) into law. The bill includes a number of tax, health care, and energy-related provisions. We will continue to evaluate the tax provisions of the bill, but do not anticipate the bill to have a material impact on our consolidated financial statements.

Fair Value Disclosures [Abstract]

Fair Value

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. DT Midstream makes certain assumptions it believes that market participants would use in pricing assets or liabilities, including assumptions about risk, and the risks inherent in the inputs to valuation techniques. DT Midstream believes it uses 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. DT Midstream classifies 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 DT Midstream has 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.

Debt

DEBT

Credit Agreement

As of September 30, 2022, DT Midstream's Credit Agreement provided for a 7-year term loan facility and a $750 million 5-year secured revolving credit facility. On October 19, 2022, DT Midstream amended the Credit Agreement to increase the Revolving Credit Facility commitments by $250 million to aggregate commitments of $1.0 billion and to extend the maturity date to October 19, 2027. See Note 11, "Subsequent Events" to the Consolidated Financial Statements.

Debt Issuances

On June 9, 2021, DT Midstream issued senior unsecured notes of $1.1 billion in aggregate principal amount due June 15, 2029 (the "2029 Notes") and $1.0 billion in aggregate principal amount due June 15, 2031 (the "2031 Notes").

In April 2022, DT Midstream issued $600 million in aggregate principal amount of 4.300% senior secured notes due April 2032 (the "2032 Notes"). The 2032 Notes are guaranteed by certain of DT Midstream's subsidiaries and secured by a first priority lien on certain assets of DT Midstream and its subsidiary guarantors that secure DT Midstream's existing credit facilities. The 2032 Notes have a security fall away provision where the collateral securing the notes will be released if DT Midstream receives an investment-grade rating from two of the three credit rating agencies. As part of the issuance of the 2032 Notes, DT Midstream's capitalized debt issuance and discount costs are approximately $4 million and $1 million, respectively.

Debt Redemptions

DT Midstream used $593 million of the net proceeds from the sale of the 2032 Notes to make a partial repayment on our existing indebtedness under our Term Loan Facility. As a result, required quarterly principal payments were eliminated, and the remaining Term Loan Facility balance is not due until maturity in 2028. There were no prepayment costs in conjunction with the partial redemption of the Term Loan Facility. The early redemption resulted in a loss on extinguishment of debt of $9 million and loss on modification of debt of $4 million relating to the write-off of unamortized discount and issuance costs, which was recorded as a loss from financing activities on DT Midstream’s Consolidated Statements of Operations for the nine months ended September 30, 2022.

The Credit Agreement covering the Term Loan Facility and Revolving Credit Facility includes financial covenants that DT Midstream must maintain. These covenants restrict the ability of DT Midstream and its 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 its 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. At September 30, 2022, the debt service coverage ratio, the consolidated net leverage ratio and the interest coverage ratio was 7.1 to 1, 3.4 to 1 and 6.2 to 1, respectively, and DT Midstream was in compliance with these financial covenants.

Commitments and Contingencies

COMMITMENTS AND CONTINGENCIES

From time to time, DT Midstream is 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. DT Midstream cannot predict the final disposition of such proceedings. DT Midstream regularly reviews legal matters and records 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 DT Midstream’s business, financial condition and results of operations.

Guarantees

In certain limited circumstances, DT Midstream enters into contractual guarantees. DT Midstream may guarantee another entity's obligation in the event it fails to perform and may provide guarantees in certain indemnification agreements. DT Midstream did not have any guarantees of other parties' obligations as of September 30, 2022.

Vector Pipeline Line of Credit

DT Midstream is the lender under a revolving term credit facility to Vector Pipeline, 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 Pipeline may only draw upon the facility if the funds are required to respond to a catastrophic event. The maximum potential payout at September 30, 2022 is USD $51 million. The funding of a loan under the terms of the credit facility is considered remote.

Environmental Contingencies

In order to comply with certain state environmental regulations, DT Midstream has an obligation to restore pipeline right-of-way slope failures that may arise in the ordinary course of business in the Utica and Marcellus shale region. Slope restoration expenditures are typically capital in nature. As of September 30, 2022 and December 31, 2021, DT Midstream had accrued contingent liabilities of $20 million for future slope restoration expenditures. The accrual is included in Other current liabilities and Other liabilities in the Consolidated Statements of Financial Position. DT Midstream believes the accrued amounts are sufficient to cover estimated future expenditures.

Accounting Policies [Abstract]

Basis of Presentation

Basis of Presentation

The Consolidated Financial Statements and Notes to Consolidated Financial Statements as of and for periods subsequent to July 1, 2021, the date of the Separation, reflect the consolidated financial position, results of operations and cash flows for DT Midstream as an independent company. Prior to the Separation, DT Midstream operated as a consolidated entity of DTE Energy and not as a standalone company. For the periods prior to the Separation, the Consolidated Financial Statements and Notes to Consolidated Financial Statements were prepared on a carve-out basis using the consolidated financial statements and accounting records of DTE Energy. The carve-out basis financial statements represent the historical financial position, results of operations, and cash flows of DT Midstream as they were historically managed in accordance with GAAP and reflect significant assumptions and allocations. The carve-out financial statements may not include all expenses that would have been incurred had DT Midstream existed as a standalone entity. Certain prior-period amounts have been reclassified to conform to current-year presentation.

GAAP requires 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 DT Midstream’s estimates. DT Midstream believes the assumptions underlying these financial statements are reasonable.

In DT Midstream's 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 September 30, 2022, results of operations for the three and nine months ended September 30, 2022 and 2021, statement of changes in stockholders' equity/member's equity for the three and nine months ended September 30, 2022 and 2021 and cash flows for the nine months ended September 30, 2022 and 2021. The balance sheet as of December 31, 2021 was derived from audited annual financial statements, but does not contain all of the footnote disclosures from the annual financial statements. 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, 2022. The Consolidated Financial Statements should be read in conjunction with the DT Midstream Consolidated Financial Statements and Notes to Consolidated Financial Statements included in DT Midstream's 2021 Annual Report on Form 10-K.

Principles of Consolidation

Principles of Consolidation

DT Midstream consolidates all majority-owned subsidiaries and investments in entities in which we have a controlling influence. Non-majority owned investments are accounted for using the equity method of accounting when DT Midstream is able to significantly influence the operating policies of the investee. When DT Midstream does 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. DT Midstream eliminates all intercompany balances and transactions.

DT Midstream evaluates whether an entity is a VIE whenever reconsideration events occur. DT Midstream consolidates VIEs for which we are the primary beneficiary. If DT Midstream is not the primary beneficiary and an ownership interest is held, the VIE is accounted for under the equity method of accounting. When assessing the determination of the primary beneficiary, DT Midstream considers 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. DT Midstream performs ongoing reassessments of all VIEs to determine if the primary beneficiary status has changed.

The maximum risk exposure for consolidated VIEs is reflected on DT Midstream’s Consolidated Statements of Financial Position. For non-consolidated VIEs, the maximum risk exposure of DT Midstream is generally limited to its investment, notes receivable, future funding commitments, and amounts which it has guaranteed.

DT Midstream owns an 85% interest in the Stonewall Gas Gathering VIE and is the primary beneficiary, therefore Stonewall Gas Gathering is consolidated. Stonewall Gas Gathering has contracts in which certain construction risk was designed to pass-through to customers, with DT Midstream retaining operational and customer default risk. DT Midstream owns a 50% interest in the South Romeo VIE and is the primary beneficiary, therefore South Romeo is consolidated.

Cash and Cash Equivalents

Cash and Cash EquivalentsCash 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.

DT Midstream regularly monitors the credit quality of its financing receivables by reviewing counterparty credit quality indicators and monitoring for triggering events, such as a credit rating downgrade or bankruptcy. DT Midstream has 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 September 30, 2022. As of September 30, 2022, the Notes receivable — related party of $4 million, which originated prior to 2021, was classified as internal grade 1.

Notes receivable are typically considered delinquent (past due) when payment is not received for periods ranging from 60 to 120 days. DT Midstream ceases accruing interest income (nonaccrual status) and may either write off or establish an allowance for expected credit loss for the note receivable when it is expected that all principal or interest amounts due will not be collected in accordance with the note's contractual terms. In determining an allowance for expected credit losses for or the write off of notes receivable, DT Midstream considers the historical payment experience and other factors that are expected to have a specific impact on collection, including existing and future economic conditions.

Cash receipts for notes receivable on nonaccrual status that do not bring the account contractually current are first applied to contractually owed past due interest, with any remainder applied to principal. Recognition of interest income is generally resumed when the note receivable becomes contractually current.

DT Midstream had an investment in certain assets in the Utica shale region which was accounted for as a Note receivable — third party. In the second quarter 2021, we assessed the note receivable for expected loss and recorded a $19 million loss on the note receivable to Asset (gains) losses and impairments, net on the Consolidated Statement of Operations. Additionally, DT Midstream ceased accruing interest on the note receivable balance and reclassified the note to an Internal grade 3 receivable. Subsequently, as cash payments were received, a portion was recognized as interest income. A third party purchased our investment in certain assets in the Utica shale region based on significantly improved commodity pricing during the second quarter 2022 for proceeds of $22 million. This resulted in a gain of $17 million recorded in Asset (gains) losses and impairments, net on the Consolidated Statement of Operations. DT Midstream maintains no continuing involvement with the note receivable.

There are no notes receivable on nonaccrual status and no past due financing receivables as of September 30, 2022.

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 specific circumstances of the associated receivable. Uncollectible expense (recovery) was zero for the three and nine months ended September 30, 2022 and 2021.

There is no allowance for expected credit loss related to Notes Receivable or Accounts Receivable as of September 30, 2022 or December 31, 2021.

Recently Issued Pronouncements

Recently Adopted Pronouncements

In March 2020, the FASB issued ASU No. 2020-04, Reference Rate Reform (Topic 848) - Facilitation of the Effects of Reference Rate Reform on Financial Reporting, as amended. Subsequently, in January 2021, the FASB issued ASU No. 2021-01, Reference Rate Reform (Topic 848) - Scope, as amended. The amendments in these updates provide optional expedients and exceptions for applying GAAP to contract modifications and hedging relationships, subject to meeting certain criteria, that reference LIBOR or another reference rate expected to be discontinued. The guidance can be applied prospectively from any date beginning March 12, 2020 through December 31, 2022. The optional relief is temporary and cannot be applied to contract modifications and hedging relationships entered into or evaluated after December 31, 2022. DT Midstream adopted this standard which did not have a material impact on our Consolidated Financial Statements.

Revenue

Revenue is measured based upon the consideration specified in a contract with a customer at the time when performance obligations are satisfied. A performance obligation is a promise in a contract to transfer a distinct good or service or a series of distinct goods or services to the customer. Pipeline revenues consist of services related to the gathering, transportation and/or storage of natural gas. Gathering revenues consist of services related to the gathering, processing, and/or treating of natural gas. Pricing for such services may consist of demand rates, usage rates and other associated fees. Certain of our Gathering contracts allow for the recovery of production-related operating expenses, which are recorded as revenue. Revenue is recognized when performance obligations are satisfied by transferring control over a service to a customer, which occurs when the service is provided to the customer. When a customer simultaneously receives and consumes the product or service provided, revenue is recognized over time. Alternatively, if it is determined that the criteria for recognition of revenue over time is not met, the revenue is considered to be recognized at a point in time. DT Midstream primarily provides two types of revenue services: firm service and interruptible service. Firm service revenue contracts are typically long-term and structured using fixed demand charges or minimum volume commitments with fixed deficiency fee rates. This provides 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. Interruptible service revenue contracts contain fixed usage rates, with total consideration dependent on actual natural gas volumes that flow.
