ONEOK 2025-26: EBITDA $8.1B Guide, $500M Synergies Realized
FY25 revenue $33.63B (+55%); Op income $6.97B (+39%); EBITDA $7.79B (+18%); NI $3.40B (+12%); EPS $5.42 (+5%). 12th consecutive year of adj EBITDA growth. Magellan + EnLink + Medallion + Easton acquisitions fully embedded; ~$500M cumulative synergies since Magellan. FY26 guide: adj EBITDA $8.1B midpoint, NI ~$3.45B / EPS $5.45, $150M incremental acquisition synergies.
Key takeaways
- 12th consecutive year of adj EBITDA growth. Net income +12% to $3.39B; adj EBITDA +18% to $8.02B. M&A integration + organic volume growth + commodity exposure all contributing.
- Multi-acquisition integration substantially complete. Magellan + Easton + EnLink + Medallion all fully embedded into the FY25 base. ~$500M cumulative synergies realized since Magellan close. FY26 to add another $150M incremental acquisition synergies.
- ~90% fee-based earnings. Diversified, scaled, integrated energy infrastructure with predominantly fee-based revenue — the structural read on ONEOK's earnings stability vs commodity-cycle midstream peers.
- FY26 guide: adj EBITDA $8.10B midpoint. Net income ~$3.45B / EPS $5.45. Implied EBITDA growth +1% from FY25's $8.02B (+18% prior year). Conservative-to-pragmatic; mgmt has historically beaten through-cycle.
- Q1 FY26 expected lowest quarter due to 90 days vs 92 in other quarters + weather impacts. Pattern of seasonality in midstream operations.
Business
ONEOK is one of the largest US midstream energy infrastructure companies post-multi-acquisition integration (Magellan 2023, Easton, EnLink, Medallion). Three reporting segments + corporate:
- Natural Gas Liquids (NGL) (~40% of revenue): NGL gathering + processing + transportation + fractionation across mid-continent + Permian + Bakken + Gulf Coast. The legacy ONEOK franchise.
- Refined Products + Crude (post-Magellan) (~40% of revenue): Refined products pipeline (gasoline, diesel, jet fuel) + crude oil gathering + transport + storage. Magellan brought the refined products + crude footprint.
- Natural Gas Pipelines + Storage (~20% of revenue): Natural gas transportation + storage + processing. Includes Williston Basin pipeline + EnLink natural gas gathering.
Strategic position: ONEOK now operates one of the most diversified midstream platforms in North America — NGLs + refined products + crude + natural gas. The diversification + ~90% fee-based earnings makes it one of the most defensive midstream plays.
Magellan (closed 2023, $19B): largest acquisition, brought refined products pipeline + crude infrastructure. EnLink + Medallion + Easton: smaller bolt-ons extending Permian + mid-continent exposure.
FY25 financial performance
| Metric (FY) | 2023 | 2024 | 2025 |
|---|---|---|---|
| Revenue ($B) | 17.68 | 21.64 | 33.63 |
| Gross profit ($B) | 5.75 | 5.05 | 7.22 |
| Op income ($B) | 4.07 | 5.02 | 6.97 |
| Op margin | 23.0% | 23.2% | 20.7% |
| EBITDA ($B) | 5.11 | 6.60 | 7.79 |
| Adj EBITDA ($B) | ~5.5 | ~6.8 | 8.02 |
| Net income ($B) | 2.66 | 3.04 | 3.40 |
| Diluted EPS ($) | 5.48 | 5.17 | 5.42 |
| FCF ($B) | 2.83 | 2.87 | 2.45 |
| Capex ($B) | -1.60 | -2.02 | -3.15 |
| Total debt ($B) | 21.76 | 32.29 | 32.82 |
| Dividends ($B) | -1.84 | -2.31 | -2.58 |
The earnings print: Revenue +55% reflects Magellan/Easton/EnLink/Medallion full year contribution. Op margin compressed to 20.7% from 23.2% — segment mix shift from higher-margin NGL to lower-margin refined products. Adj EBITDA +18% on synergy realization + organic growth. EPS $5.42 (+5%) — operating leverage moderate due to higher share count post-deals.
Capex stepped up to $-3.15B reflecting growth project investment. Total debt $32.8B held similar to FY24 (post-merger peak).
Capital allocation
- Capex: $-3.15B FY25 (9.4% of revenue) — heavy growth investment.
- Dividends: $-2.58B FY25 (+12% YoY). Continued increase trajectory.
- Buybacks: $-75M FY25 (small).
- M&A: Easton + EnLink integration completing in FY25 base; Medallion in earlier base.
- Debt: $32.82B (+$0.53B YoY). Stable post-acquisition peak.
FY26 outlook (per Q4 2025 call, 2026-02-24)
| FY26 guide | Range / point |
|---|---|
| Adjusted EBITDA | $8.10B midpoint |
| Net income | ~$3.45B |
| Diluted EPS | $5.45 |
| Crude oil assumption | WTI $55-$60/bbl |
| Q1 EBITDA seasonality | Lowest quarter (90 vs 92 days + weather) |
| Incremental acquisition synergies | ~$150M FY26 |
| EBITDA growth from increased volumes | $100M (e.g., specific project ramps) |
The +1% EBITDA growth midpoint is conservative — mgmt has consistently beaten guide. Bridge: synergies + organic volume + acquisition annualization + project ramps − cost inflation = +1-3% midpoint to high end.
Key risks
- Crude oil price: WTI $55-$60 assumption. Lower prices compress crude + refined products volume + customer activity.
- Customer concentration in upstream: Bakken + mid-continent E&P customer activity matters for NGL + crude + processing.
- Refined products demand: Magellan refined products pipeline + storage tied to gasoline + diesel + jet fuel demand. EV adoption + economic cycle exposure.
- Synergy delivery: Magellan + EnLink + Medallion + Easton integration largely complete but residual synergy capture matters.
- Interest rate environment: $32.8B debt; refinancing windows + rate cycle affect cost.
- Regulatory: Pipeline + processing facility regulatory environment + permit timelines.
Bottom line
OKE FY25 is the multi-acquisition integration completion + 12th consecutive year of adj EBITDA growth. Revenue +55% on Magellan/Easton/EnLink/Medallion full-year contributions; adj EBITDA +18% to $8.02B; ~$500M cumulative synergies + $150M FY26 additional. FY26 guide $8.1B EBITDA / $5.45 EPS / $3.45B NI. The structural read: most diversified midstream platform with ~90% fee-based earnings + capital return discipline. Risks are crude oil cycle + refined products demand + interest rates.
