ONEOK, INC.
ONEOK, INC. is a Private limited company (Ltd.) registered in United States under 1900584812, and its current status with Oklahoma Secretary of State is inactive. The company was incorporated on 16 May 1997 and lists its registered address as United States. 2 shareholders are on record for ONEOK, 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 Oklahoma Secretary of State and was last updated on 3 October 2026.

Shareholders
2
Two shareholders are currently on record for ONEOK, 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 20.9% — the largest recorded stake — followed by UBS Group AG at 2.4%.
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 | 20.9% | Oklahoma Secretary of State | |
| UBS Group AG | 2.4% | Oklahoma Secretary of State |
Officers
5
The President, Ceo & Director of ONEOK, INC. currently on record is Pierce H. Norton Ii; five officers are currently on record for ONEOK, INC., filed with Oklahoma Secretary of State.
The register reports 14 officers in total, including past appointments, though only the 5 most relevant records are shown here.
Management authority at ONEOK, 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
ONEOK, INC. has no recorded parent company — it sits at the top of its own group structure, with 80 subsidiaries recorded beneath it across 1 jurisdiction. 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 80 subsidiaries span United States jurisdiction, 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. Five of the 80 go a level deeper still, with their own further subsidiaries recorded beneath them — additional ownership layers this view doesn't expand.
