MAMMOTH ENERGY SERVICES, 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 Oklahoma City, United States. 2 shareholders are on record for MAMMOTH ENERGY SERVICES, 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.

Data availability
Those 35 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. Two of the 35 go a level deeper still, with their own further subsidiaries recorded beneath them — additional ownership layers this view doesn't expand.

Frequently asked questions
Who owns MAMMOTH ENERGY SERVICES, INC.?
