Oneok

ONEOK, based in Tulsa, Oklahoma, is a midstream energy company that gathers, processes, fractionates, transports, stores and exports natural gas, natural gas liquids (NGLs), refined products and crude oil through an approximately 60,000-mile pipeline network; it calls itself one of the largest integrated energy infrastructure companies in North America. Its four segments are Natural Gas Liquids, Refined Products and Crude (from the 2023 Magellan acquisition), Natural Gas Gathering and Processing, and Natural Gas Pipelines. Earnings were about 90% fee-based in 2025. Revenue was $33,629 million, net income attributable to ONEOK $3,393 million and adjusted EBITDA $8,020 million, after the January 2025 completion of the EnLink acquisition. In September 2026 an Apollo affiliate invested $9 billion in a new ONEOK Holdings entity for Class B units with a capped return of 7.01% for the first nine years, and on October 6, 2026 ONEOK bought Brazos Midland for about $4.6 billion.

  • ▲

    Revenue grew +31.5% a year over 5 years (strong growth)

    From $8.54B in FY2020 to $33.63B in FY2025. The annualized rate (CAGR) makes it possible to compare growth pace across companies of different sizes.

  • ▲

    Operating margin improved: 15.9% → 17.1%

    How much operating profit is left per $100 of revenue. It moved +1.1 points over 5 years — pricing power, cost control, and product mix all show up here.

  • ―

    Equity ratio is 33.7% (a middling level)

    The share of total assets funded by equity rather than debt. 50%+ is often read as low bankruptcy risk, though the right level varies by industry (real estate and leasing run lower, for instance).

  • ―

    Free cash flow was positive in 5 of 6 years

    Operating cash flow minus capital expenditures: the cash left over after funding the business’s own investment, available for dividends, buybacks, acquisitions, or debt paydown. A negative year can mean heavy investment, or weak core earnings — worth distinguishing.

  • ▲

    ROE averaged 20.2% over 6 years (latest: 17.2%)

    How much profit was generated on shareholders’ equity. Roughly 10%+ is often cited as solid for a U.S. company, though this varies a lot by industry and capital intensity.

Is ROIC above WACC?From SEC data

ROIC (the return on money invested in the business) above WACC (the cost of raising that money) means the company is creating value. WACC is an estimate, so its assumptions can be adjusted below.

What the price implies (DCF)From SEC data

A company's value can be written as its free cash flow divided by (cost of capital − perpetual growth). Working that backwards from the market's valuation shows how much growth the share price assumed — compared here with the company's actual past growth.

Growth the price implies (price on 2026-11-04)

3.7%

Perpetual FCF growth: g = r − FCF ÷ EV = 6.5% − 2.7%

Past FCF growth (FY2020–FY2025)

—

Not computable (FCF not positive in both years)

Past revenue growth (FY2020–FY2025)

+31.5%

Compound annual rate, 5 years

Inputs (FY2025): free cash flow $2.45B (operating CF − capex); enterprise value $89.94B = market cap $56.38B (latest close, 2026-11-04) + debt $33.64B − cash and short-term investments $78M; r = WACC of 6.5% using this page’s default assumptions (β 0.59, risk-free 5.0%, market premium 5.5%).

Three WACC scenarios

The same calculation under cautious, base and optimistic cost-of-capital assumptions (risk-free rate fixed at the 10-year Treasury yield). Pick one to load it into the sliders below.

Try your own assumptions

V = FCF ÷ (r − g). It starts at the implied growth rate, where the theoretical value equals today’s enterprise value.

Theoretical enterprise value

$87.39B

FCF $2.45B ÷ (6.5% − 3.7%)

Theoretical ÷ actual enterprise value

0.97x

Below 1x: these assumptions value the business below the market did

How sensitive the answer is

Theoretical ÷ actual enterprise value for each combination of r and g.

6%——5.44x1.81x1.09x
8%————5.44x

A simplified model for seeing what the market price assumes, not a forecast or a target price. It treats free cash flow as growing at one constant rate forever; the result swings widely with small changes in r and g, and is undefined when g reaches r. Free cash flow here is operating cash flow minus capex, which is after interest — a full DCF of enterprise value would use cash flow before interest. Market cap uses the latest close (2026-11-04) × shares at fiscal year-end; free cash flow and WACC inputs are from the latest fiscal year.

What changed in the risk factorsFrom SEC data

Paragraphs in the latest 10-K's Risk Factors that have little overlap with the year before, and paragraphs that were dropped.

New or substantially reworded (3)

  • In addition, scrutiny regarding climate change and other ESG matters has resulted in an increased likelihood of governmental investigations, regulation, shareholder activism and private litigation by both advocates and opponents of such matters, which could increase our costs or otherwise adversely affect our business. For example, while some policymakers (including certain states and the SEC under the previous administration) have adopted, or are considering adopting, requirements for the disclosure of climate risks or other information, other policymakers have sought to constrain companies’ considerations of ESG matters. Any failure to successfully navigate stakeholder expectations, including regulatory developments, may result in reputational harm, increased costs or other adverse impacts.

  • We engage in various efforts to respond to stakeholder expectations; Read more

    however, such efforts may not have the desired effect. Many of these efforts rely on methodologies, assumptions and data (including third-party information) that are subject to varying interpretations or that continue to evolve, including in ways we cannot control. Our approach may also continue to evolve, and we cannot guarantee that our approach will align with the expectations or preferences of any particular stakeholder. For example, our emissions reduction targets depend on a range of factors, and to the extent these do not manifest or we otherwise are unable to make progress on such targets or other initiatives, we may face additional costs or be unable to meet our targets, which could negatively impact our business and reputation. Various of our business partners and other stakeholders are subject to similar…

  • Upon entering office, the new administration issued a series of executive orders that signal a shift in the United States’ energy, environmental and climate change policy. Read more

    Among other directives, such executive orders: (i) direct federal agencies to identify and exercise emergency authorities to facilitate conventional energy production, transportation and refining and call for the use of emergency regulations to expedite energy infrastructure projects; (ii) promote energy explorations and production on federal lands and waters; (iii) mandate a review of existing regulations that may burden domestic energy development; and (iv) rescission of funds and programs related to the IRA and Infrastructure Investment and Jobs Act. We continue to assess the long-term impacts of such actions on our operations, if any. However, such actions may prompt various states and other policymakers to take…

No longer in the text (4)

  • In addition, increasing attention to climate change has resulted in an increased likelihood of governmental investigations, regulation, shareholder activism and private litigation, which could increase our costs or otherwise affect adversely our business. For example, the SEC finalized new climate change disclosure requirements in March 2024 but stayed the rules in April 2024 pending judicial review of several lawsuits filed by states, industry and environmental groups challenging the rule. It is unclear when the rules will become effective, if at all. If these or any other climate disclosure requirements become effective, we may face increased costs associated with complying with such new climate disclosure rules.

  • Certain investors are increasingly focused on ESG issues, including climate change. Read more

    Further, organizations that provide information to investors on corporate governance and related matters have also increased their focus on ESG issues and have developed ratings processes for evaluating companies on various ESG initiatives. Unfavorable ESG ratings may lead to increased negative investor sentiment toward us or midstream companies in general. Due to climate change concerns, some investors may choose not to invest, or to reduce investment, in companies that explore for, produce, process, transport or sell products derived from hydrocarbons. If this negative investor sentiment increases, we may see reduced demand for our securities, which could impact our liquidity or the value of our securities. Additionally, certain large institutional lenders have announced their own policies to meet…

  • In 2021, we announced a companywide absolute GHG emissions reduction target of 2.2 million metric tons of carbon dioxide equivalents from our combined Scope 1 and Scope 2 emissions by 2030 for our legacy ONEOK assets. Read more

    The target represents a 30% reduction in combined operational Scope 1 and location-based Scope 2 GHG emissions attributable to ONEOK assets as of Dec. 31, 2019. To the extent that the potential pathways we have identified to achieve this emissions reduction target are not available to us, or to the extent we otherwise are unable to make progress toward other ESG-related targets we may establish, we may face additional costs to meet these targets, or we may fail to meet them, which could negatively impact our business and reputation.

  • We may be unable to integrate the businesses of EnLink and Medallion successfully or realize the anticipated benefits of the EnLink Acquisitions and the Medallion Acquisition (collectively, the “Recent Acquisitions”).
