Is OKE a Buy? What to Consider in 2026
Short answer
The bull case for ONEOK (OKE) rests on Fee-Based Revenue Durability: Approximately 90% of ONEOK's 2026 earnings are expected to come from fee-based contracts, insulating cash flow from short-term swings in natural gas and NGL prices. Revenue (FY 2025) is ~$33.6 billion. If you believe that thesis holds, the real questions become position sizing and overlap, not timing. The main risk to that view: ONEOK's Net Debt to EBITDA stands at approximately 4x, which is elevated even by midstream standards, and the 2026 adjusted EBITDA guidance range of approximately $7.9 to $8.3 billion was viewed by some analysts as essentially flat versus 2025, raising questions about near-term earnings momentum. Whether OKE is a buy comes down to whether you believe the thesis. This is informational, not a recommendation, and Walnut is not an investment adviser.
ONEOK (NYSE: OKE) is an American midstream energy company headquartered in Tulsa, Oklahoma. It provides gathering, processing, fractionation, transportation, storage, and marine export services for natural gas, natural gas liquids, crude oil, and refined products across four reportable business segments. The company operates approximately 60,000 miles of pipeline and earns the majority of its revenue through long-term, fee-based contracts that limit direct commodity price exposure. Roughly 90% of 2026 earnings are expected to be fee-based, making cash flow relatively predictable across commodity price cycles. Founded in 1906 as Oklahoma Natural Gas Company and renamed ONEOK in 1980, the company has been publicly traded on the NYSE for decades and is a member of both the Fortune 500 and S&P 500. CEO Pierce H. Norton II has led a series of large-scale acquisitions including the 2023 Magellan Midstream merger, the 2024 Medallion Midstream acquisition, and the full purchase of EnLink Midstream completed in early 2025. These deals broadened ONEOK's footprint into the Permian Basin, Mid-Continent, and Gulf Coast markets, more than doubling processed natural gas volumes and catapulting revenue from approximately $21.7 billion in 2024 to approximately $33.6 billion in 2025.
What's the case for buying OKE?
Fee-Based Revenue Durability
Approximately 90% of ONEOK's 2026 earnings are expected to come from fee-based contracts, insulating cash flow from short-term swings in natural gas and NGL prices. Long-term minimum-volume commitments underpin revenue visibility. This structure supports consistent dividend payments and debt reduction without requiring commodity prices to cooperate.
Acquisition Synergy Capture
ONEOK captured approximately $475 million in cumulative synergies from the EnLink and Medallion acquisitions through year-end 2025, and the integrated system continues to generate operational efficiencies. The full ownership of EnLink, completed in February 2025, consolidates control over a large Permian and Mid-Continent asset base. As integration matures, incremental synergies and cross-selling of capacity should expand margins further.
Natural Gas and NGL Volume Growth
Rocky Mountain region NGL raw feed throughput volumes grew 15% year over year in 2025, and natural gas processed volumes across the system are guided to a range of approximately 5,410 to 6,170 million cubic feet per day in 2026. Growing use of longer lateral well completions is expected to drive higher per-well throughput for ONEOK's gathering systems. Structural demand drivers including LNG exports, industrial use, and power generation for AI data centers support a multi-year volume growth case.
Deleveraging and Capital Discipline
ONEOK retired approximately $3.1 billion of long-term debt during 2025, demonstrating a firm commitment to balance sheet repair after its acquisition spree. A $2 billion share repurchase program is also active, returning capital alongside the quarterly dividend. Continued free cash flow generation, estimated at approximately $2.5 billion for fiscal 2025, provides flexibility to simultaneously pay down debt and invest in organic growth projects.
What are the risks to OKE?
ONEOK's Net Debt to EBITDA stands at approximately 4x, which is elevated even by midstream standards, and the 2026 adjusted EBITDA guidance range of approximately $7.9 to $8.3 billion was viewed by some analysts as essentially flat versus 2025, raising questions about near-term earnings momentum. A material slowdown in U.S. producer activity, particularly in the Permian Basin or Rocky Mountain region, could reduce throughput volumes and stress the fee-based model. Commodity-linked portions of earnings remain exposed to NGL price cycles, and further large acquisitions or integration missteps could delay the deleveraging trajectory. Regulatory changes affecting pipeline operations or carbon emissions standards represent an additional longer-term uncertainty.
How is OKE valued? (as of 2026-06-27)
- Revenue (FY 2025): ~$33.6 billion
- Net Income (FY 2025, attributable to ONEOK): ~$3.39 billion
- Adjusted EBITDA (FY 2025): ~$8.02 billion
- Diluted EPS (FY 2025): ~$5.42
- P/E Ratio (TTM, approx.): ~15x to 16x
- Dividend Yield (forward, approx.): ~4.7% (annualized dividend of $4.28/share)
ONEOK's trailing P/E of approximately 15x to 16x sits modestly below its peer group average of roughly 17.5x and well below its own 10-year historical average of approximately 23x, reflecting market uncertainty around integration complexity and a cautious 2026 volume outlook. The EV/EBITDA multiple of approximately 11x is consistent with large-cap midstream peers and suggests the market is pricing in a period of consolidation rather than re-acceleration. Free cash flow of approximately $2.5 billion in fiscal 2025 comfortably covers the dividend, supporting the roughly 76% payout ratio.
How do you decide if OKE is a buy?
Rather than asking whether OKE is a buy in the abstract, it tends to help to answer four questions:
- Thesis: do you believe the case above, and is it still true today?
- Time horizon: a single stock can be volatile, so a longer horizon absorbs more of the swings.
- Position sizing: a thesis can be right and the sizing still wrong; decide how much of your portfolio one name should be.
- Overlap: check whether you already hold OKE indirectly through an index or sector ETF before adding more.

However, elevated leverage from recent acquisitions and a cautious 2026 earnings outlook introduce meaningful near-term uncertainty that investors should weigh carefully.

Some DCF-based models suggest the stock may be trading below intrinsic value, though the elevated debt load and flat 2026 EBITDA guidance temper the enthusiasm of some analysts. Valuation depends heavily on assumptions about long-term volume growth and synergy realization.
