ONEOK (OKE) Q2 2026 earnings review

Record Volumes and Wide Spreads Drive Another Guidance Raise

ONEOK delivered a strong Q2 2026, prompting management to raise full-year earnings guidance for the second consecutive quarter. Adjusted EBITDA grew 7% YoY to $2.12B, and Net Income climbed 13% to $967M. The standout performer was the Natural Gas Pipelines segment, which saw EBITDA surge 58% driven by highly favorable Waha-to-Katy price differentials. However, underlying segment performance was mixed. The Natural Gas Liquids (NGL) segment reversed into a slight decline (-2% EBITDA) despite record throughput, dragged down by escalating operating costs. Management's raised FY26 outlook reflects confidence that broad-based volume momentum and infrastructure completions will outweigh the inevitable normalization of current commodity spreads.

🐂 Bull Case

Successive Guidance Hikes

For the second straight quarter, ONEOK raised its FY26 guidance. Adjusted EBITDA midpoint is now $8.35B, up from the original $8.10B provided at the end of 2025, showing strong operational execution and constructive market conditions.

Robust Volume Growth Across the System

Physical throughput is accelerating. Refined products shipments rose 8%, natural gas processed increased 2%, and NGL raw feed throughput hit record levels, growing 7% YoY.

🐻 Bear Case

Margin Compression in the NGL Segment

Despite a 7% jump in NGL volumes, segment Adjusted EBITDA shrank by 2% YoY to $659M, revealing negative operating leverage caused by rising employee and outside service costs.

Over-Reliance on Temporary Spreads

A significant portion of the quarter's outperformance came from a $77M gain in optimization/marketing tied to wide Waha-to-Katy price differentials, a tailwind management previously acknowledged will normalize as new industry pipelines come online.

⚖️ Verdict: 🟢

Bullish. The scale of the integrated system is effectively capturing regional price dislocations and rising volumes. While creeping operating costs require monitoring, the successive guidance raises validate ONEOK's fundamental earnings power.

Key Themes

DRIVER NEW 🟢🟢

Natural Gas Pipelines Breakout

The Natural Gas Pipelines segment is accelerating rapidly. EBITDA surged 58% YoY to $297M. The primary catalyst was a $77M boost from optimization and marketing, exploiting highly favorable price differentials between the Permian's Waha Hub and the Katy market in Texas. Firm transportation revenues also added $19M. This segment has evolved from a steady baseline to a major growth driver in the current market environment.

CONCERN NEW 🔴

NGL Segment Margins Squeezed by Costs

A concerning divergence emerged in ONEOK's largest business unit. The trend is reversing: while NGL raw feed throughput hit a record 1,630 MBbl/d (+7% YoY), segment Adjusted EBITDA fell to $659M (-2% YoY). The volume gains were entirely consumed by an $18M increase in operating costs (employee and outside services) and a $6M drag from lower transportation/storage volumes. Growth in this segment is currently yielding negative operating leverage.

DRIVER 🟢

Refined Products Volume Ramp

The Refined Products and Crude segment remains stable and highly profitable. EBITDA grew 13% YoY to $627M. This was propelled by a $79M increase in transportation and storage revenues tied to an 8% increase in refined product volumes shipped (1,629 MBbl/d) and higher tariff rates. Crude marketing also contributed an additional $48M. Crucially, the Greater Denver refined products pipeline expansion achieved mechanical completion in early August, cementing capacity for future quarters.

CONCERN

System-Wide Operating Cost Inflation

ONEOK is paying a steep price for its operational growth. Operating costs surged across multiple segments. In Refined Products and Crude, costs spiked by $48M due to project timing, higher employee headcount, and a $9M property tax hike. Natural Gas Gathering & Processing (G&P) operating costs also rose $22M. While overall profitability grew, these structural cost increases are suppressing margin expansion.

THEME 🟢

Data Center & LNG Mega-Trend Intact

Though not explicitly updated with new commercial contracts in the Q2 press release, ONEOK's long-term macro setup remains anchored to explosive demand from AI data centers and LNG exports. Previous quarters highlighted 'advanced discussions' for pipeline projects ranging from $400M to $700M to serve this emerging power load. The company’s sprawling footprint in Texas and Oklahoma serves as a vital structural advantage to bridge Permian supply with Gulf Coast demand.

Other KPIs

H1 Operating Cash Flow $2.99 billion

Accelerating significantly from $2.43B in H1 2025. This 23% YoY increase provides massive financial flexibility, comfortably funding the $1.48B in H1 capital expenditures while maintaining the $4.28 annualized dividend.

Commodity Sales Revenue (Q2) $10.8 billion

Top-line revenue exploded by 60% YoY from $6.7B in 25Q2. While the vast majority of this is a direct pass-through of higher commodity prices (cost of sales concurrently jumped to $9.2B from $5.3B), it illustrates the sheer scale and utilization of ONEOK's trading and optimization network.

Guidance

FY26 Adjusted EBITDA $8.2 - $8.5 billion

Accelerating. Management bumped the midpoint to $8.35 billion, an upgrade from the $8.25 billion midpoint set in Q1, and well above the original $8.1 billion guide provided at the end of 2025. This implies roughly 4% YoY growth against the $8.02B achieved in FY25.

FY26 Net Income $3.41 - $3.79 billion

Accelerating. The midpoint of $3.6 billion represents a $100M raise from the Q1 outlook. Implies approximately 6% YoY growth versus the $3.39 billion reported in 2025.

FY26 Capital Expenditures $2.7 - $3.2 billion

Stable. Total CapEx guidance remains entirely unchanged, implying that ONEOK is generating the recent earnings upside without needing to deploy unplanned incremental capital.

Key Questions

NGL Segment Margin Recovery

With raw NGL feed throughput hitting record highs but EBITDA slipping 2% YoY, what specific operating cost controls are being implemented to ensure volume growth translates into bottom-line profit in H2 2026?

Spread Normalization Timeline

The Natural Gas Pipelines segment gained $77M from wide Waha-to-Katy differentials. At what point in late 2026 do you expect new third-party pipeline capacity to permanently crush this spread, and what replaces that earnings stream?

Data Center Contracts Update

Following 'advanced discussions' noted in Q1 regarding $400M-$700M data center supply projects, what is the timeline for moving these from the discussion phase to final investment decisions?
