ONEOK, Inc. Overview

Pro stress-test →

ONEOK delivers energy products and services as a leading midstream operator that provides gathering, processing, fractionation, transportation, storage and marine export services. Through its approximately 60,000-mile pipeline network, the company transports natural gas, natural gas liquids (NGLs), refined products and crude oil that help meet domestic and international energy demand.

The company's financial profile is strong, underpinned by a resilient, fee-based business model, with approximately 90% of 2025 revenues projected to come from long-term, take-or-pay contracts.

Competitive Landscape

In natural gas liquids, ONEOK's primary competitors include Enterprise Products Partners (EPD), Energy Transfer (ET), and Kinder Morgan (KMI), with Enterprise Products Partners operating one of the largest NGL pipeline networks in North America.
