DT Midstream, Inc. 2025 Annual Report (10-K) Summary

Business Context and Reporting Period

This Form 10-K covers the fiscal year ended December 31, 2025. DT Midstream, Inc. is an owner, operator, and developer of an integrated portfolio of natural gas midstream assets, operating primarily in the Midwestern U.S., Eastern Canada, Northeastern U.S., and Gulf Coast regions. The company operates through two reportable segments: Pipeline (interstate/intrastate pipelines, storage, and gathering laterals) and Gathering (gathering systems and treatment plants). A key strategic milestone in 2025 was the full-year integration of the Midwest Pipeline Acquisition (Guardian, Midwestern, and Viking pipelines) acquired in late 2024.

Key Financial Metrics

Segment Performance: The Pipeline segment generated $687 million in revenue and $370 million in net income. The Gathering segment generated $556 million in revenue and $71 million in net income.

Material Changes vs. Prior Period

• Revenue Growth: Consolidated operating revenues increased 27% to $1.243 billion, driven primarily by the full-year contribution of the Midwest Pipeline Acquisition ($212 million), new LEAP contracts ($31 million), and higher storage revenue.
• Profitability: Net income attributable to DT Midstream increased 25% to $441 million. Operating income rose to $614 million.
• Customer Concentration: Expand Energy accounted for approximately 45% of total operating revenues in 2025, down from 56% in 2024.
• Debt Structure: The company achieved an Investment Grade Event in May 2025, resulting in the release of collateral on senior notes and the Revolving Credit Facility. The Term Loan Facility was fully repaid in September 2024.
• Capital Deployment: Total capital investments were $431 million, focused on expansions at Blue Union Gathering, Appalachia Gathering, LEAP, and Stonewall.

Guidance, Outlook, and Risks

Outlook and Strategy: Management anticipates total capital investments for 2026 to range between $490 million and $570 million. The company continues to pursue a natural gas-centric strategy with disciplined capital deployment. Key growth projects include the Guardian G3 expansion (expected service Q4 2028) and further LEAP expansions.

Dividend Policy: The company expects to grow its dividend with cash flow growth. A quarterly dividend of $0.88 per share was declared on February 19, 2026.

Risks and Contingencies:

• Customer Concentration: Significant reliance on Expand Energy (45% of revenue) poses a risk if volumes decline or contracts are not renewed.
• Regulatory Environment: Operations are subject to FERC, PHMSA, and state regulations. Changes in climate change legislation (e.g., methane emissions) or pipeline safety rules could increase compliance costs.
• Legal Proceedings: Pending litigation with Antero Resources regarding Stonewall rate provisions could result in a loss range of $0 to $55 million, though no accrual has been recorded as a loss is not deemed probable.
• Market Risk: Fluctuations in natural gas prices and production levels in key basins (Marcellus/Utica, Haynesville) could impact throughput volumes.

Investor Verification Checklist

• Midwest Pipeline Integration: Verify the realization of synergies and the full-year financial impact of the Guardian, Midwestern, and Viking assets.
• Expand Energy Exposure: Monitor the status of contracts with Expand Energy, which represents nearly half of total revenue.
• Capital Expenditure Execution: Track progress on the Guardian G3 expansion and LEAP Phase 4 to ensure they remain on budget and schedule.
• Regulatory Compliance: Review updates on PHMSA leak detection rules and FERC rate proceedings for the newly acquired pipelines.
• Stonewall Litigation: Monitor the outcome of the trial with Antero Resources regarding rate provisions.
• Debt Covenants: Confirm continued compliance with the consolidated net leverage ratio (2.9 to 1 as of year-end) following the Investment Grade Event.
