Koppers Holdings Inc.
Koppers Holdings Inc. is a Private limited company (Ltd.) registered in United States under 3261656, and its current status with Pennsylvania Department of State is active. The company was incorporated on 12 November 2004 and lists its registered address as Harrisburg, United States. 2 shareholders are on record for Koppers Holdings Inc., and since every one of them is a company rather than an individual, this particular filing does not on its own establish an ultimate beneficial owner (UBO) — identifying one would mean tracing the ownership of each shareholding company in turn. This profile is sourced directly from Pennsylvania Department of State and was last updated on 2 October 2026.

Shareholders
2
Two shareholders are currently on record for Koppers Holdings Inc., reflecting the stock ledger maintained under state corporate law (e.g. §219 of the Delaware General Corporation Law) rather than a public filing.
The largest of these is Vanguard Group Inc, holding 9.1% — the largest recorded stake — followed by Fidelity Salem Street Trust-Fidelity Small Cap Index Fund at 1.1%.
Because every shareholder shown is a company rather than an individual, the ownership chain continues above this level, and no beneficial owner can be established from this filing alone.
| Shareholder | Type | Holding | Source Document |
|---|---|---|---|
| Vanguard Group Inc | 9.1% | Pennsylvania Department of State | |
| Fidelity Salem Street Trust-Fidelity Small Cap Index Fund | 1.1% | Pennsylvania Department of State |
Officers
5
The Chairman, Ceo & Director of Koppers Holdings Inc. currently on record is Leroy Mangus Ball Jr.; five officers are currently on record for Koppers Holdings Inc., filed with Pennsylvania Department of State.
The register reports 15 officers in total, including past appointments, though only the 5 most relevant records are shown here.
Management authority at Koppers Holdings Inc. sits with these individuals, not with shareholders, who are covered separately and hold ownership rather than control.
The source filing doesn't specify representation authority — whether officers can act individually or must sign jointly to bind the company — so that detail isn't available here.
Group Structure
Koppers Holdings Inc. has no recorded parent company — it sits at the top of its own group structure, with 27 subsidiaries recorded beneath it across 4 jurisdictions. Each of these downward relationships is derived rather than filed: resolved by matching entities across the registry network, not stated directly in a single document.
Those 27 subsidiaries span United States, Chile, United Kingdom, Mauritius jurisdictions, though this list should not be read as complete — subsidiaries only become visible here where shareholder data has actually been filed with a register, so holdings in jurisdictions without that filing simply won't appear. Three of the 27 go a level deeper still, with their own further subsidiaries recorded beneath them — additional ownership layers this view doesn't expand.
