Delek US (DK) Q3 2026 earnings review
Delek US wins biofuel waivers, and fuel margins lift profit
Delek US, an operator of four southern US oil refineries and a pipeline network, turned surging fuel margins and federal biofuel waivers into record earnings. Revenue jumped 52%, while profit per share excluding one-offs and biofuel waivers reached $10.53 as all four plants ran at full capacity. Chief executive Avigal Soreq raised the annual cost-savings target to $250 million and lifted the bottom of the pipeline unit's outlook, though by our math that plan leaves fourth-quarter pipeline profit down 12%.
| Revenue | $4,392.1M +52% from a year ago |
|---|---|
| Profit per share, excluding one-offs and biofuel waivers | $10.53 $1.52 a year ago |
| Parent net cash (excluding Delek Logistics) | $21.9M $202.1M net debt last quarter |
| Full-year Logistics EBITDA outlook | Raised $10M middle of the range: $545M |
⚖️ Verdict: 🟢 Bullish
The story got better because the Environmental Protection Agency approved all of the refiner's 2025 biofuel waivers, removing a major cash risk and cutting third-quarter material costs by $335 million. Alongside a stock sale at the pipeline partnership, that windfall moved the parent company into a net cash position and set up the repayment of its $850 million term loan. One caution: headline adjusted figures still pre-book half of 2026's unapproved waivers, even as the El Dorado plant runs above the 75,000-barrel-per-day small-refinery limit.
The question now is how much profit Delek US can keep when Gulf Coast fuel margins retreat from triple last year's level and 2026 waiver petitions face review. If the $250 million optimization plan is real and pipeline gas volumes keep climbing, the business can generate cash in a normal market; if wide fuel spreads did the work, earnings will drop back. Fourth-quarter refining capture rates and the 2026 waiver rulings will decide it.
🐂 Bull Case
EPA Grants Full 2025 Biofuel Waivers
United States refiners must blend biofuels or buy compliance credits known as RINs, unless the Environmental Protection Agency (EPA) grants a small refinery exemption (SRE). A major risk was that the agency would deny Delek US's pending petitions, forcing it to pay hundreds of millions of dollars in cash for past obligations.
In August, the agency granted "a full exemption with respect to all Delek refineries for the 2025 compliance year" and approved Krotz Springs's 2024 waiver after a court ruling. Those approvals cut third-quarter material costs by $334.7 million, and falling credit prices added a $377.8 million fair-value gain. The multi-year regulatory backlog is now cleared.
What to watch: the exact cash proceeds from selling returned biofuel credits in the third-quarter filing. That cash inflow funds the planned repayment of the $850 million term loan in the fourth quarter.
Wide Fuel Margins Triple Per-Barrel Profit
Chief executive Avigal Soreq attributed the record quarter to "smooth operations, access to advantaged barrels, and industry leading distillate and jet yield". With no planned maintenance after the first-quarter work at Big Spring, all four refineries ran at 100.2% of crude oil capacity and processed 316,291 barrels per day, beating the company's own 296,000 to 316,000 plan.
- Benchmark crack spreads (the price gap between crude oil and refined fuel): up 191.2% from a year ago, with the Gulf Coast 5-3-2 benchmark at $63.52 per barrel versus $22.57
- Refining production margin excluding biofuel waivers: $38.56 per barrel, up from $9.59 a year ago and $19.84 last quarter
- El Dorado capture rate (the share of the benchmark margin the refinery kept): 52.9%, up from 35.4% last quarter
- Cost of materials and other: fell by 18.6 percentage points of revenue from a year ago, lifting consolidated gross margin by 22.2 percentage points
What to watch: fourth-quarter refining capture rates if fuel prices ease from summer peaks. Holding El Dorado's capture rate above 45% would show that operational fixes, not just market prices, are lifting margins.
Parent Erases Net Debt as Pipeline Unit Separates
"As the economic separation between DK and DKL increases, we believe both companies are better positioned to unlock their respective standalone value," Soreq said. Delek Logistics (DKL), the company's pipeline and water partnership, sold 4.6 million common units at $50 each in August. That sale raised $230 million to pay down partnership debt and lowered the parent company's ownership stake from 63.0% in June to 58.0%.
Inside the partnership, natural gas gathering and processing in the Delaware Basin rose 16.2% from last quarter to 93,777 thousand cubic feet per day. Excluding Delek Logistics, the parent company ended September with $1,286.1 million in cash against $1,264.2 million in debt, moving from $202.1 million of net debt in June to $21.9 million of net cash.
What to watch: completion of the sour-gas gathering and compression equipment near the Libby plant in the fourth quarter. Bringing that equipment online is needed to deliver the $60 million of extra partnership profit Soreq targets for 2027.
Cost Plan Target Rises to $250 Million
Delek US runs a cost-cutting and efficiency programme called the Enterprise Optimization Plan (EOP). Soreq raised the programme's annual cash-flow improvement target from $220 million to at least $250 million, marking the fourth increase in five quarters. General and administrative overhead fell from $76.8 million a year ago to $53.4 million, or by 1.4 percentage points of revenue, while refining operating costs dipped 7 cents to $5.36 per barrel.
What to watch: a breakdown of where the extra $30 million of annual savings sits on the income statement. Without line-item detail, investors cannot separate permanent cost cuts from wide refining margins.
🐻 Bear Case
Profit Still Rests on Unapproved 2026 Waivers
Delek US headlines $1,280.4 million in third-quarter EBITDA (earnings before interest, taxes, depreciation and amortization) excluding one-offs, and $13.55 in profit per share. Since late 2025, however, the company has adjusted those headline figures to pre-book half of the biofuel waivers it expects to win for the current year, before the EPA rules on them.
Stripping out all biofuel waiver adjustments, third-quarter EBITDA was $1,038.1 million ($242.3 million lower than the headline) and profit per share was $10.53 ($3.02 lower). For the first nine months of 2026, pre-booking unapproved 2026 waivers added $372.7 million to headline EBITDA. Meanwhile, the El Dorado refinery processed 79,027 barrels per day of crude oil in the quarter and 77,315 over nine months, running above the 75,000 threshold for small-refinery relief.
What to watch: the EPA's ruling on 2026 waiver petitions, particularly for El Dorado. A denial there would force Delek US to reverse part of the $372.7 million adjustment it has already booked this year.
Share Count Rises Despite Buybacks and New Debt
Delek US bought back $50.0 million of its own stock in the third quarter, raised its quarterly dividend by 18% to $0.30 per share, and plans up to $100 million of fourth-quarter buybacks. Yet diluted share count rose 2.1% from a year ago to 62.2 million, because employee stock awards outpaced repurchases. In September, the refiner also issued $460 million of zero-coupon convertible notes due 2031 to help repay its term loan, adding future dilution risk if the notes convert.
What to watch: weighted-average diluted shares in the fourth quarter after the planned $100 million buyback. If the share count does not fall, stock compensation and convertible instruments are absorbing the cash returned to shareholders.
Fuel Margins Remain a Cyclical Risk
Refining windfalls depend on global fuel supply gaps thatDelek US does not control. In the first nine months of 2025, when the Gulf Coast 5-3-2 benchmark crack spread averaged $19.96 per barrel, the company posted a GAAP operating profit of just $136.4 million and a net loss of $101.1 million. This quarter's $1,518.9 million operating profit required a $63.52 benchmark spread, nearly triple last year's level.
What to watch: Gulf Coast diesel and gasoline crack spreads in the fourth quarter as seasonal driving slows. A drop back toward $25 per barrel would test Soreq's claim that the company can generate strong free cash flow through the cycle.
💲 Other KPIs
Operating cash flow jumped from $44.0 million a year ago and $262.9 million in the second quarter. After subtracting $116.5 million of cash used in investing activities, free cash flow reached $450.9 million by our math, or 10.3% of revenue, even after an $808.8 million working-capital cash outflow during the quarter.
Customer receivables rose 55.1% from December to $1,006.4 million, and fuel inventories climbed 49.4% to $1,084.6 million, outpacing the 34.2% nine-month revenue increase. Higher oil and fuel prices tied up $808.8 million of working capital in the third quarter, keeping operating cash flow well below the $1,133.8 million net income.
🔮 Guidance
Raised. Delek US lifted the bottom of the partnership's full-year profit outlook by $10 million, putting the middle of the range at $545 million, up 2.9% from 2025 by our math. With $418.8 million already earned in the first nine months, the middle of the range leaves $126.2 million for the fourth quarter by our math, down 11.7% from the third quarter despite rising gas volumes.
Raised. The refiner increased its annual cash-flow improvement target by $30 million. It is the third raise in four quarters, following moves of +$20 million in the fourth quarter, +$20 million in the first, and $0 in the second. Soreq also reiterated a target to add $60 million of the partnership's $75 million profit growth plan in 2027.
❓ Key Questions
Will El Dorado's volume cost it a 2026 waiver?
El Dorado processed 79,027 barrels per day of crude oil in the third quarter and 77,315 over nine months, above the 75,000 small-refinery limit. Meanwhile, Delek US has already pre-booked $372.7 million of 2026 waiver benefits in its year-to-date headline EBITDA.
Where do the $250 million cost savings show up?
Soreq raised the annual cash-flow improvement target to at least $250 million, but refining operating expenses per barrel only dipped from $5.43 to $5.36 from a year ago. Investors need a bridge to specific income-statement lines.
What is the fourth-quarter refinery throughput and cost plan?
Unlike prior quarters, the earnings release did not print fourth-quarter ranges for refinery throughput, operating expenses, or interest costs. Those figures show whether the four plants can hold 100% utilization into winter.
Is the Libby sour-gas compression equipment online yet?
Delek Logistics planned to finish its sour-gas gathering and compression equipment near the Libby gas plant in the second half of 2026. Completing it is key to hitting the $60 million profit addition targeted for 2027.
