What DT Midstream, Inc. told the SEC could break it.

DT Midstream depends on one key customer, Expand Energy (Haynesville and Marcellus producer), for ~45% of 2025 operating revenues; loss of, or reduced volumes from, this customer would materially harm results.

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

DT Midstream lacks asset and geographic diversification — substantially all pipeline, storage and gathering systems are in the Midwestern US, Eastern Canada, Northeastern US and Gulf Coast — so adverse developments (catastrophic events, weather, regulation) in those areas could disproportionately harm it.

“We rely primarily on revenues generated from our pipeline, storage and gathering systems, substantially all of which are located in the Midwestern U.S., Eastern Canada, Northeastern U.S. and Gulf Coast regions. Due to our lack of diversification in assets and geographic location, an adverse development in these businesses or our areas of operations, including adverse developments due to catastrophic events, weather, regulatory”

DT Midstream's interstate pipelines are FERC rate-regulated (NGA civil penalties up to ~$1.58M/violation/day, recent Guardian max-tariff cut of ~13%), and its cross-border US-Canada gas operations face import/export licensing and potential tariffs/counter-measures that could adversely affect results.

“For example, tariffs or other restrictions placed on the import and export of natural gas with Canada and any related counter-measures that are taken by Canada could have an adverse effect on our financial condition or results of operations. Even in the absence of further tariffs, the related uncertainty could have a material adverse effect on our business, liquidity, financial condition or results of operations.”

DT Midstream depends on third-party interstate and intrastate pipelines and facilities that interconnect with its assets to provide receipt and delivery; if those interconnected pipelines become unavailable, it could materially harm volumes and results.

“If third-party pipelines and other facilities interconnected to our assets become unavailable to transport natural gas, it could materially adversely affect our business, financial condition and results of operations. We depend upon third-party pipelines and other facilities that provide receipt and delivery options to and from our assets.”
