ONEOK (OKE) Q3 2026 Earnings: Record Refined Products Profit From Blending

ONEOK (OKE) third-quarter 2026 earnings show record profit in its refined products and crude business, but most of the increase came from blending and marketing rather than pipeline fees. The company reported the results for the quarter ended September 30, 2026 through an earnings release on October 27 and a 10-Q and earnings call on October 28. Adjusted EBITDA was $2.238 billion, up 6% year over year, and ONEOK raised its full-year guidance again [1][2][3].

Four earlier questions about the company now have answers. Refined Products and Crude earnings hit a record, but the gain relied on blending and marketing. The lower NGL profit mainly reflects revenue deferred by limited fractionation capacity. Natural gas pipeline spread income fell back as the company expected. The Apollo transaction has completed its debt reduction. Overall, volumes and the balance sheet are improving, but a larger share of profit now depends on price spreads, and whether it repeats still needs to be tested.

ONEOK is a midstream energy company based in Tulsa. It runs four segments: natural gas gathering and processing, natural gas liquids (NGLs), natural gas pipelines, and refined products and crude. It provides transportation and processing services to producers, refiners and exporters [4]. About 90% of its 2025 earnings were fee-based [5].

Refined Products and Crude: Record Profit Driven by Blending and Marketing

The segment's third-quarter adjusted EBITDA was $685 million, up 18% year over year and above $627 million in the second quarter [2][6]. Refined products volumes shipped were 1,615 thousand barrels per day, up 6%. The year-over-year increase in operating costs narrowed to $18 million from $48 million in the second quarter [1][2][6]. These figures met the earlier standard for judging whether the segment's growth would continue.

Most of the gain came from spread-related income. Of the $103 million increase, higher liquids blending earnings added $67 million, crude marketing added $20 million, and margin-sharing terms in certain crude contracts added $35 million. Higher refined products volumes contributed only $23 million [2]. Part of the volume growth came from marketing affiliate volumes and the timing of refinery disruptions [2].

Only part of the blending gain is likely to last. Management said moving butane from trucks to pipelines cut logistics costs by about 10 cents per gallon, which it called a permanent saving. Wide spreads and the timing of the September gasoline standard change are cyclical, and the company did not give amounts for each factor [3]. The segment's profit level is therefore confirmed. Whether fee-based business can hold profit when marketing income falls has not yet been tested.

NGLs: The Profit Decline Is Mainly a Timing Issue

NGL raw feed throughput reached a record 1,661 thousand barrels per day, up 6% year over year. Segment adjusted EBITDA was $718 million, above $659 million in the second quarter but below $748 million a year earlier [2]. Estimated profit per barrel was about $4.70, compared with about $5.17 a year earlier.

The decline mainly reflects when revenue is recognized. A higher inventory of unfractionated NGLs reduced revenue by $45 million, narrower price differentials cut only $5 million, and higher volumes added $28 million [2]. The company said its fractionators are full, so new raw feed goes into inventory and the related fees are recognized only after fractionation. Medford Phase I is expected to start in mid-December, and the deferred earnings are expected mostly in the first quarter of 2027 [3]. The size of the inventory was not disclosed.

Apollo Transaction: Debt Reduction Completed

In September, ONEOK used the $9 billion Apollo investment to extinguish $5.462 billion of debt principal. Total debt was $28.520 billion at September 30, down $4.502 billion from June 30 [2]. The carrying amount fell by less than the principal because the repurchased notes had been recorded below par [2]. Credit ratings rose to BBB+, and the leverage target was lowered to about 3.25 times or less [3].

The jump in earnings per share came mainly from a one-time item. Third-quarter diluted EPS was $2.13, including a $336 million reorganization tax benefit, or $0.53 per share. Excluding it, EPS was about $1.60, compared with $1.49 a year earlier [1]. Net income attributable to noncontrolling interests of $34 million covered only about 21 days. From the fourth quarter, the 7.01% return will accrue for a full quarter and offset most of the interest savings [1][2].

Natural Gas Pipelines: Spread Income Halved

Natural Gas Pipelines adjusted EBITDA was $231 million, compared with $297 million in the second quarter. The estimated marketing margin fell from $123 million to $63 million, while transportation revenue rose 17% year over year [2]. Management expects spreads to keep narrowing in the fourth quarter [3].

Conclusion

The third quarter shows broad volume growth at ONEOK, but the profit increase leans toward spread-sensitive businesses, and NGL growth is temporarily deferred. ONEOK raised its 2026 adjusted EBITDA guidance to $8.5 billion to $8.6 billion. Of the $200 million increase in the midpoint, about $100 million comes from the base business, and the rest from transaction gains and the Brazos acquisition completed on October 6 [1][2][3]. Operating cash flow for the first nine months was $4.366 billion, up 7.7%, covering capital spending and dividends, but Apollo will receive 15% of operating cash flow each quarter [1][2]. The fourth quarter will test these conclusions: whether Refined Products and Crude profit stays above $627 million, whether deferred NGL earnings are recognized once Medford starts, and the net effect of noncontrolling-interest charges versus interest savings.
