What is OKE's rating?
Our latest published rating for OKE, analyzed 2026-09-28, is Reduce, with a published moat assessment of 6.5/10 (Narrow). It reflects our fair value of USD 74.7, the potential value of USD 80.6, and the price recorded at analysis (USD 88.6).
Accelerated commercialization of the 400 MMcf/d Bighorn processing plant expansion by mid-2027 expands Permian capacity to 2.4 Bcf/d, while capital spending moderates toward $2.0B-$2.5B post-2027.
Main risk
Operating margin compressing below 14.0% (down from 17.07% in FY2025) as lower-rate discretionary ethane recovery outpaces full-rate C3+ liquids across the Permian, Mid-Continent, and Bakken basins,.
We assign ONEOK Inc. a Reduce rating as the shares trade at an 18.6% premium to our Fair value of $74.71, driven by $32,816 million in total debt and an elevated capital expenditure build that restrict near-term free cash flow,,,.3
The house rating is Reduce. For an ordinary investor, this recommendation advises trimming existing holdings or waiting for a more favorable entry price. Current equity pricing reflects an aggressive operational expansion without providing sufficient compensation for elevated balance sheet debt and capital spending demands.
The analysis was prepared with the stock priced at $88.63 as of September 25, 2026. This report-date price trades 18.6% above our house Fair value midpoint of $74.71, representing an implied downside of 15.71%. The report-date price also stands 10.0% above our Potential value of $80.59, leaving no valuation cushion for equity investors.3
The primary risk to this outlook is that operating margin compression and refinancing costs undermine debt repayment. If operating margin drops below 14.0%—compared with 17.07% in FY2025 due to higher discretionary ethane recovery, —or if refinancing rates rise on its $32,816 million debt load, annual interest expense will absorb operating earnings and stall deleveraging. A reader would observe this deterioration through falling operating margins and stagnant quarterly cash generation.3,4,6
The business can outperform if its capital projects accelerate cash generation ahead of schedule. The 400 million cubic feet per day Bighorn plant expansion is scheduled to complete in mid-2027, bringing Permian processing capacity to nearly 2.4 billion cubic feet per day. When capital expenditures moderate from $3,152 million toward $2.0 billion to $2.5 billion, and new data center power interconnects begin delivery, free cash flow will expand above FY2025 levels of $2,447 million, providing support toward our Potential value of $80.59.4,5,6
Dominant Natural Gas Liquids Export Infrastructure
ONEOK's natural gas liquids network delivered $16,010 million in FY2025 revenue, anchored by a 100% contracted Seabrook export terminal under firm take-or-pay commitments and 500,000 bpd Bakken egress capacity.4,7
With the 400 MMcf/d Bighorn processing plant expansion scheduled for mid-2027 completion, management projects capital expenditures will moderate from $3,152 million to $2.0B-$2.5B,, enabling cash generation to shift to debt reduction.4,6
Data Center Power Supply Opportunities
The company secured a 1 GW power generation supply contract for data centers requiring modest capital of approximately $100 million at firm demand, establishing an attractive non-cyclical growth vector.
House recommendation
We rate ONEOK Reduce because shares at $88.63 trade at an 18.6% premium to our Fair value of $74.71 while $32,816 million in total debt and heavy capital spending constrain near-term free cash flow,,,.3
Company overview
ONEOK INC /NEW/ provides midstream services to producers of NGLs in the Rocky Mountain region, Mid-Continent region, Permian Basin and Gulf Coast region and deliver those products to the market. Its primary markets include the Mid-Continent in Conway, Kansas, the Gulf Coast in Mont Belvieu, Texas, Louisiana and the upper Midwest.
Property - Its Refined Products and Crude segment includes the following wholly owned assets: Unconsolidated Affiliates - Its Refined Products and Crude segment includes the following unconsolidated affiliates:
Under joint stress conditions, lower-margin discretionary ethane volumes dilute operating margins below 14.0%,, while revenue from the primary anchor customer (12.0% of FY2025 revenue) contracts. Facing $32,816M in total debt, a 200 bps rise in pre-tax borrowing costs above 8.35% adds over $650M in interest expense to the $1,783M paid in FY2025, eliminating free cash flow expansion and stalling debt deleveraging.
ONEOK holds a narrow economic moat derived from efficient scale across its integrated midstream network and contractual switching costs embedded in long-term take-or-pay acreage dedications. The company connects prolific supply basins in the Bakken, Mid-Continent, and Permian to Gulf Coast fractionation and export docks, creating high barriers to duplicate pipeline egress,.
Economic returns confirm modest competitive advantage, with return on invested capital of 8.60% exceeding the computed cost of capital (WACC of 7.04%). However, ONEOK's operating margin of 17.07% lags pure-play transmission peers such as Kinder Morgan (30.07%) and Williams Companies (39.54%), while a 12.0% revenue concentration in a single customer limits pricing power.

Upgrade the rating; Re-examine margin realization across processing facilities and verify commercial progress on power interconnects before altering exposure.
Trigger: NGL throughput volume acceleration across key basins alongside discretionary ethane margin recovery and disciplined capital reinvestment.
A sharp operational beat would demonstrate that higher-margin liquids demand offsets discretionary ethane dilution, improving operating margin stability.
In-line
Maintain Reduce; Maintain disciplined exposure trimming toward target weightings and monitor debt paydown milestones at forthcoming earnings releases.
Trigger: Volume throughput matching consensus projections with stable fee realizations and planned execution on active capital projects.
Inline operating performance confirms that heavy debt service and elevated transformation capital outlays continue to limit near-term free cash flow.
Miss
Downgrade the rating; Accelerate risk mitigation actions, verify minimum volume commitments with anchor shippers, and review debt covenant headroom.
FY2025 CapEx reached $3,152M against D&A of $1,514M (CapEx/D&A of 2.08x), tracking the industry benchmark CapEx to depreciation ratio of 2.13 and CapEx to revenue of 19.6%. Reinvestment is driven by the Bighorn processing plant expansion to 400 MMcf/d.4,6
Bull cycle
Sustained global LPG and crude export demand pulls high volumes through Gulf Coast docks, while new data center power interconnects accelerate EBITDA growth without heavy capital requirements,.
Bear cycle
Upstream producer drilling curtailments reduce basin throughput, leading to unabsorbed pipeline capacity and lower fee revenues against high fixed debt service obligations.
§11 Position management
Sizing
0-1%
Under the committee Reduce rating, an underweight portfolio allocation of 0-1% is recommended. Shares trade at $88.63 as of 2026-09-25, representing an 18.63% premium over the Fair value midpoint of $74.71, while balance sheet debt of $32,816M leaves limited downside protection.3
Risk
Manage portfolio risk by maintaining underweight exposure, enforcing strict stop-loss discipline against operating margindilution, and requiring debt reduction milestones before considering re-entry.

Level
§12 Investor perspectives
Total Return / Value Investor
Avoid
Shares trade at an 18.6% premium to our Fair value of $74.71 as of September 25, 2026,. With $32,816 million in total debt and trailing operating margin of 17.07%, the risk-reward skew is unfavorable.3,6
Income / Dividend Investor
Hold
The dividend yield is supported by $5,599 million in operating cash flow, but FY2025 dividends paid of $2,583 million exceeded free cash flow of $2,447 million due to $3,152 million in CapEx. Existing holders can maintain positions for current income while monitoring debt coverage, but should not add new capital.
§14 Final recommendation
Action
Reduce
We recommend a Reduce stance on ONEOK Inc. Shares trade at $88.63 as of September 25, 2026, which is an 18.6% premium to our Fair value of $74.71,. While core NGL export assets remain durable, elevated debt of $32,816 million and an active capital transformation build keep free cash flow constrained and expose equity holders to downside if margins compress.3
Investors should trim portfolio allocations toward an underweight weighting of 0-1%. With dividend payments of $2,583 million exceeding FY2025 free cash flow of $2,447 million and requiring debt financing, valuation re-entry should wait until the stock trades below the Fair value midpoint of $74.71 and capital spending moderates.

The downside scenario is driven by prolonged drilling deceleration across producer acreage, sustained margin compression from discretionary ethane recoveries, customer concentration disruption, or persistent refinancing headwinds on acquisition debt. Outside this section, downside targets remain unquoted, but these operational pressures would severely restrict free cash flow inflection and impede debt paydown.
Ways this thesis can break
Severe commodity spread compression and discretionary ethane volume dilution leading to sustained operating margin contraction
CCO Sheridan Swords confirmed midstream margin compression driven by increased lower-rate discretionary ethane recovery across the Permian, Mid-Continent, and Bakken relative to full-rate C3+. If operating margin falls below 14.0% (down from 17.07% in FY2025), owner earnings and debt service coverage are severely impaired.4,6

Customer concentration shock from volume curtailment or contract renegotiation by top shipper
A single customer accounted for 12.0% ($4,035M) of consolidated FY2025 revenue,. If upstream producer distress or contract renegotiation reduces top customer revenue below $3.0 bn, top-line contraction accelerates and unabsorbed pipeline capacity creates severe operating deleverage on the $32,816M debt base.3,6,7

Prolonged high interest rate environment driving refinancing cost escalation on acquisition debt load
ONEOK carries $32,816M in total debt with an existing pre-tax cost of debt of 6.35%. If refinancing rates push pre-tax borrowing costs above 8.35% (+200 bps), annual interest expense increases by over $650M beyond FY2025 levels of $1,783M, suppressing owner earnings.1,3,6

Early-warning signals to monitor
The five developments that would weaken our investment case.
Operating margin compression caused by increased lower-rate discretionary ethane recovery across the Bakken and Permian, reducing operating income from $5,741M.
Erosion in NGL volume throughput or realized fees below $16,010M indicating basin market share loss or sustained pricing weakness across gathering networks.
ONEOK generates returns on invested capital of 8.60%, exceeding its computed WACC of 7.04% by 1.56 percentage points, confirming positive economic spread over a 10-year competitive advantage horizon.1
6.5/ 10
Narrow
Sources of advantage
01Efficient Scale in NGL Logistics — ONEOK's integrated pipeline systems provide indispensable egress from the Bakken running up to 500,000 bpd and West Texas expanded to 740,000 bpd, where duplicating physical infrastructure would be economically unviable for competing operators.Wide
02Contractual Switching Costs — Seabrook export terminal is 100% contracted under firm take-or-pay agreements into the foreseeable future, and upstream gathering volumes are anchored by long-term acreage dedications, including 12.0% of FY2025 revenue from a single core shipper.Moderate
Steady volume throughput across NGL logistics and export infrastructure
Execution of major Permian processing projects within projected capital budgets
Predictable fee-based cash flow under take-or-pay acreage dedications
Gradual deleveraging as major capital construction concludes
The modal path reflects steady baseline throughput supported by firm export commitments at the Seabrook terminal and multi-year acreage dedications. Capital expenditures remain elevated through mid-decade to complete processing additions before moderating, aligning intrinsic value with Fair value at $74.71 relative to $88.63.
Accelerated gathering and processing volume growth across core basins
Bighorn processing capacity expansion commissioned ahead of schedule
Expansion of data center power supply commitments beyond initial agreements
Capital spending normalizes promptly toward recurring maintenance requirements
In the upside path, accelerated volume growth across Permian and Bakken gathering networks combines with prompt commercialization of the Bighorn plant expansion and rapid expansion of data center power supply agreements. Operating leverage expands net margins while capital spending moderates, driving substantial free cash flow expansion and rapid debt reduction toward Potential value at $80.59.
Operating margin contraction from discretionary ethane dilution, producer volume curtailments, or project cost overruns.
An earnings shortfall highlights operating deleverage across capital-intensive pipeline networks, compounding balance sheet debt pressure.
Operating cash flow expanded to $5,599M in FY2025, delivering approximately $0.97 of operating cash for every $1.00 of operating profit. However, capital expenditures of $3,152M reduced free cash flow to $2,447M. Because total dividends paid reached $2,583M, organic cash flow did not fully cover distributions, contributing to net debt issuance of $830M.5,6
Capital allocation is dominated by the transformation build and acquisition debt management. Total debt stands at $32,816M with pre-tax borrowing cost of 6.35%, requiring $1,783M in annual interest expense. Management has guided that post-2027 CapEx will moderate from $3,152M down to $2.0B-$2.5B once Bighorn is completed, which will be vital for debt deleveraging.
