Organization, Consolidation and Presentation of Financial Statements [Abstract] |
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. We provide multiple, integrated natural gas services to customers through two segments: (i) Pipeline, which includes interstate pipelines, intrastate pipelines, storage systems, gathering lateral pipelines including related treatment plants and compression and surface facilities, and (ii) Gathering, which includes gathering systems, related treatment plants, and compression and surface facilities. Our Pipeline segment also includes joint venture interests in equity method investees which own and operate interstate pipelines that connect to our wholly owned assets. On December 31, 2024, we closed on the Midwest Pipeline Acquisition of three FERC-regulated interstate natural gas transmission pipelines. See Note 12, "Acquisition" to the Consolidated Financial Statements. Our core assets strategically connect key demand centers in the Midwestern U.S., Eastern Canada and Northeastern U.S. regions to the premium production areas of the Marcellus/Utica natural gas formation in the Appalachian Basin, and connect key demand centers and LNG export terminals in the Gulf Coast region to premium production areas of the Haynesville natural gas formation. Basis of Presentation The Consolidated Financial Statements and Notes to Consolidated Financial Statements are prepared under GAAP. These accounting principles require management to use estimates and assumptions that impact reported amounts of assets, liabilities, revenues and expenses, and the disclosure of contingent assets and liabilities. Actual results may differ from our estimates. We believe the assumptions underlying these financial statements are reasonable. In our opinion, the accompanying unaudited Consolidated Financial Statements include all adjustments, consisting of normal recurring adjustments, necessary to present a fair statement of our financial position as of September 30, 2025, results of operations for the three and nine months ended September 30, 2025 and 2024, and cash flows for the nine months ended September 30, 2025 and 2024. The Consolidated Statement of Financial Position as of December 31, 2024 was derived from audited annual financial statements but does not include all disclosures required by GAAP. Financial results for this interim period are not necessarily indicative of results that may be expected for any other interim period or for the year ending December 31, 2025. The Consolidated Financial Statements should be read in conjunction with DT Midstream's Consolidated Financial Statements and Notes to Consolidated Financial Statements included in DT Midstream's 2024 Annual Report on Form 10-K. Cash Management Our sources of liquidity include cash generated from operations and available borrowings under our Revolving Credit Facility. Principles of Consolidation We consolidate all majority-owned subsidiaries and investments in entities in which we have a controlling influence. Non-controlled investments are accounted for using the equity method of accounting when we are able to significantly influence the operating policies of the investee. When we do not influence the operating policies of an investee, the equity investment is measured at fair value, if readily determinable, or if not readily determinable, at cost less impairment, if applicable. We eliminate all intercompany balances and transactions. We evaluate whether an entity is a VIE whenever reconsideration events occur. We consolidate VIEs for which we are the primary beneficiary. When assessing the determination of the primary beneficiary, we consider all relevant facts and circumstances, including: the power, through voting or similar rights, to direct the activities of the VIE that most significantly impact the VIE's economic performance and the obligation to absorb the expected losses and/or the right to receive the expected returns of the VIE. We perform ongoing reassessments of all VIEs to determine if the primary beneficiary status has changed. We own an 85% interest in the Stonewall VIE and are the primary beneficiary, therefore Stonewall is consolidated. We own a 50% interest in the South Romeo VIE and are the primary beneficiary, therefore South Romeo is consolidated. The following table summarizes the major line items in the Consolidated Statements of Financial Position for consolidated VIEs as of September 30, 2025 and December 31, 2024. All assets and liabilities of a consolidated VIE are included in the table when it has been determined that a consolidated VIE has either (1) assets that can be used only to settle obligations of the VIE or (2) liabilities for which creditors do not have recourse to the general credit of the primary beneficiary. The assets and liabilities of consolidated VIEs that meet the definition of a business and whose assets can be used for purposes other than the settlement of the VIEs' obligations have been excluded from the table below.

Related Parties Transactions between DT Midstream and our equity method investees have been presented as related party transactions in the accompanying Consolidated Financial Statements. Equity Method Investments Non-controlled investments are accounted for using the equity method of accounting when we are able to significantly influence the operating policies of the investee. Under the equity method of accounting, investments are recorded at historical cost as an asset and adjusted for capital contributions, dividends and distributions received, and our share of the investee's earnings or losses, which are recorded as earnings from equity method investees on the Consolidated Statements of Operations. Equity method investments and related activity are included in the Pipeline segment. Our equity method investments are periodically evaluated for certain factors that may be indicative of other-than-temporary impairment. As of September 30, 2025 and December 31, 2024, our carrying amounts of investments in equity method investees exceeded our share of the underlying equity in the net assets of the investees by $324 million and $336 million, respectively. The difference will be amortized over the life of the underlying assets. As of both September 30, 2025 and December 31, 2024, our consolidated retained earnings balance did not have undistributed earnings from equity method investments. We use the cumulative earnings approach to classify proceeds received from equity method investees as dividends or distributions on the Consolidated Statements of Cash Flows. Earnings from equity method investees include:
