Summit Carbon Sued for Second Time Over Unpaid Pipeline Bills

Company contracted to manufacture pipeline valves sues Summit for $6.6 million

Des Moines, Iowa — In a July 27, 2026 complaint filed in the U.S. District Court for the Southern District of New York, pipeline material supply company Patton Myhre sued SCS Carbon Transport (an affiliate of Summit Carbon Solutions) for breach of contract, seeking “at least $6.6 million” in damages. The complaint alleges that Summit contracted with Patton Myhre to supply 251 valves and related control equipment for use in Summit’s proposed carbon pipeline project, but failed to pay. According to Patton Myhre, “Summit simply chose not to pay”.

The complaint also alleges that in May 2025, Summit told Patton Myhre it was electing not to pursue the multi-billion dollar, multi-state pipeline project. As such, the company said Summit no longer wanted all the valves, and demanded that Patton Myhre find other buyers for the unwanted valves, as the company said Summit’s “executive leadership had decided to ‘conserve capital’ rather than pay Patton Myhre . . . ” 

This is the second major lawsuit filed against Summit by a major pipeline industry vendor. In February 2024, Welspun Tubular – one of just a few companies worldwide that produces the steel used to build pipelines – sued Summit for more than $15 million for breach of contract, after Summit tried canceling an order for the manufacturing of steel pipe. Oral arguments in that case were held last month, and a decision is forthcoming.

“This lawsuit is seemingly evidence of Summit’s limited financial capacity and its uncertainty about the design and purpose of its proposed CO2 pipeline project. Given that the Midwest Carbon Express is a multibillion dollar project, its unwillingness to pay a $6.6 million claim suggests that Summit is strapped for cash. After retaining a new CEO in 2025, Summit pushed a narrative that it was turning over a new leaf and would treat landowners and partners with the respect they deserve, but once again, Summit’s actions don’t match its words,” said Cynthia Hansen, Shelby County Landowner.

“If Summit is willing to treat multi-national business partners with such disregard, why would we expect them to treat Iowans any better? Iowans expect honesty and fair play. Summit is not Iowa nice, not acting in good faith and they can’t be trusted with just a handshake,” said Kathy Carter, landowner in Floyd County.
