What these concentrations mean together
updated 2026-06-24The company's concentration profile spans supply and customer dimensions across its three operating segments, with the most structurally significant exposure on the supply side. The coal supply for the Coyote Station operates under requirements contracts that obligate the company to purchase all necessary coal from a single counterparty — a high-share dependency that eliminates discretion in fuel sourcing for that plant and creates direct exposure to the counterparty's operational continuity and pricing. At the customer level, the Plastics segment carries moderate concentration: two customers combined accounted for 47% of Plastics segment operating revenues, and three customers accounted for 44% of Manufacturing segment operating revenues. Both are moderate-share, dependency-character exposures — individually the segments contribute only a portion of consolidated revenues, but within those segments, results are meaningfully tied to the ordering behavior of a small customer base. A material pullback by a top Plastics or Manufacturing customer would have a visible segment-level impact. The Plastics segment also faces a supply-side input risk: severe weather events in the Gulf Coast have historically disrupted PVC resin supply, a moderate-share dependency on a geographically concentrated input source. At the Electric segment level, two customers combined accounted for 16% of Electric segment revenues — a low-share customer concentration in the most regulated of the three businesses. On balance, the coal supply obligation and mid-tier customer concentrations in Plastics and Manufacturing are the most actionable variables; the Electric segment customer exposure is well-bounded.
