ONE GAS, INC.

Public Limited Company Active

in

ONE GAS, INC. is a Public Limited Company registered in United States, and its current status with Oklahoma Secretary of State is active. Its registered address on file is Tulsa, United States. 5 shareholders are on record for ONE GAS, 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 25 September 2026.
