What these concentrations mean together
updated 2026-07-06Koppers' concentration risk is modest and largely structural rather than counterparty-driven. On the customer side, the top ten customers together account for approximately 36% of aggregate net sales — a moderate share spread across ten relationships rather than a handful of dominant accounts, which limits the damage any single customer loss could inflict. The more distinctive exposure is internal: the CMC business supplies 100% of the creosote requirements for the North American RUPS business. Because this is a wholly internal supply relationship rather than dependence on an outside vendor, it functions more as an operational linkage between segments than as a counterparty risk — any disruption at CMC would ripple through to RUPS, but there is no external supplier that could walk away or raise prices unilaterally. Taken together, these two exposures net out to a relatively contained concentration profile: the customer base is broad enough that no single account is likely to swing results, and the supply dependency, while total, sits within Koppers' own operations rather than in the hands of a third party. Neither exposure stands out as the kind of acute, idiosyncratic risk that would typically pressure a verdict on its own.
