Cliffs Steel

What these concentrations mean together
updated 2026-07-06SunCoke Energy's concentration risk is customer-based and pronounced: substantially all of the company's sales are to a limited number of customers, with long-term, take-or-pay agreements naming Cleveland-Cliffs Steel Holding Corporation and Cleveland-Cliffs Steel LLC, collectively Cliffs Steel, among those customers. This is a dependency-type exposure rather than a structural, industry-wide feature — revenue is tied to the performance and contractual commitments of a small set of named counterparties rather than a broad, diversified customer base. The take-or-pay structure of the Cliffs Steel agreements provides some contractual protection against volume risk, but it also means the credit quality and continued operation of Cliffs Steel specifically is a critical variable for the business, since so much of overall sales runs through a limited customer set. This concentration is one of the more consequential disclosed in SunCoke's filing: a disruption at, or renegotiation of terms with, Cliffs Steel or another of the limited named customers would have an outsized effect on results relative to a company selling coke into a more fragmented steelmaking customer base.
