Customers

ONEOK serves producers, processors, utilities, industrial users, municipalities, and energy marketers that need midstream infrastructure to move hydrocarbons from supply basins to end markets. Its fee-based contracts are used by customers that value capacity access, reliable transportation, storage, and processing rather than direct commodity exposure.

Upstream producers

Buy gathering, processing, and transportation services to move produced gas, NGLs, and crude to market.

Midstream and marketing counterparties

Use NGL, pipeline, storage, and terminal services to balance flows and access infrastructure.

Utilities and power generators

Contract for firm pipeline and storage capacity to support reliable fuel supply.

Refining, petrochemical, and industrial customers

Buy transport, storage, and commodity-linked logistics services for feedstock and fuel delivery.

Municipal and transportation end markets

Use refined products distribution for local fuel supply, aviation, rail, and fleet demand.

Strategy

ONEOK’s strategy is to expand fee-based midstream infrastructure, deepen its presence in key operating regions, and add value-added services that diversify earnings. It also emphasizes maintaining a resilient asset base, investment-grade balance sheet discipline, and returning capital through dividends and share repurchases.

Expand fee-based midstream infrastructureMedium term

Fee-based contracts reduce direct commodity exposure and support steadier cash generation.

Develop capital projects in core basins and corridorsMedium term

New infrastructure can increase throughput, extend customer relationships, and deepen basin presence.

Preserve financial flexibilityShort term

A strong balance sheet supports large projects, acquisitions, and shareholder returns.

Broaden business mix through complementary assetsLong term

Diversification across gas, NGL, refined products, and crude reduces dependence on one commodity chain.

Geography

ONEOK’s operations are concentrated in the United States, with core infrastructure in Oklahoma, Texas, and other central U.S. energy basins and corridors. Its pipeline and logistics footprint connects producing regions to Gulf Coast, industrial, utility, and retail fuel markets, so geography directly shapes throughput, contract mix, and exposure to basin activity.

Risks

ONEOK faces commodity-linked volume risk, counterparty credit risk, and operational risks tied to pipelines, processing plants, and terminals. As a critical energy infrastructure operator, it is also exposed to cyberattacks, terrorism, regulatory changes, and impairment risk if market conditions weaken or asset utilization falls.

Accounting

Judgemental items
Commodity sales and cost of sales offset

Product sales can rise with commodity prices while cost of sales rises similarly, affecting gross presentation more than economics.

Impact: Revenue and cost of sales can both be large and volatile

Fee-based contract accounting

Transportation, storage, and processing contracts often depend on capacity, volumes, and minimum commitments.

Impact: Revenue recognition depends on contract terms and service delivery

Derivatives and hedging

ONEOK uses hedges for commodity and interest-rate exposure, which can create mark-to-market volatility.

Impact: Earnings and OCI can be affected by hedge valuation changes

Goodwill and long-lived asset impairment

Acquisitions and infrastructure assets must be tested if market conditions or utilization weaken.

Impact: Noncash charges could reduce earnings and equity

Equity-method investments

Joint ventures and pipeline interests require judgment on carrying value and recoverability.

Impact: Investment income and impairment risk can affect results
