Sunoco LP (SUN) Q3 2026 earnings review
Sunoco raises its profit plan, but higher taxes trim cash
Sunoco, the operator of fuel stations, pipelines and storage terminals, lifted its full-year profit plan on booming refinery earnings while cash flow after taxes slipped from last quarter. Third-quarter Adjusted EBITDA — cash profit before interest, taxes and depreciation — more than doubled from a year ago to $1.05 billion after adding Canadian fuel supplier Parkland, or rose 19% by our math against what the two businesses earned separately last year. That easily beat what the partnership's own plan pointed to for the second half, and net debt dropped to its 3.5 times target.
| Adjusted EBITDA | $1,049M +115% from a year ago (+19% vs combined prior year by our math) |
|---|---|
| Distributable cash flow, excluding one-offs | $588M +80% from a year ago (−3% from last quarter) |
| Fuel margin per gallon | 16.8 cents 17.1 cents last quarter |
| Full-year Adjusted EBITDA outlook | Raised now expects to beat the $3.5–3.7B range |
⚖️ Verdict: 🟢 Bullish
The story got better because Sunoco now expects to beat its $3.5 billion to $3.7 billion full-year profit range and hit its debt goal early, even after buying US distributor Offen Petroleum in October. Two cautions offset part of that strength: fuel profit per gallon dipped to 16.8 cents, and a $138 million current tax bill pulled distributable cash flow down slightly from the second quarter.
The question now is how much of the profit beat comes from lasting cost savings versus volatile refining and fuel margins. Either cost cuts from the Parkland deal are running well ahead of the $125 million annual plan, or a 99% refinery run rate is temporarily masking flat underlying volumes. Fourth-quarter results, when the year-ago comparison includes two months of Parkland, will show the true underlying growth rate.
🐂 Bull Case
Refinery Profit Jumped and Prompted an Outlook Raise
Sunoco acquired the Burnaby oil refinery in late 2025 when it bought Canadian fuel supplier Parkland. In the third quarter, the plant ran at 99% of its crude oil capacity, up from 97% in the second quarter. That steady run lifted the refinery's Adjusted EBITDA — cash profit before interest, taxes and depreciation — by 36% from last quarter to $238 million.
- Third-quarter Adjusted EBITDA: $1,049 million, or $1,060 million excluding $11 million of deal costs
- Implied second-half pace from the prior outlook: $830 million to $930 million per quarter by our math
- Refinery profit per barrel processed: about $45 by our math, up from $34 in the second quarter
Because the refinery and fuel stations beat the $830 million to $930 million quarterly pace that the old plan pointed to, the fuel distributor now "Expects to exceed 2026 Adjusted EBITDA guidance range of $3.5 billion to $3.7 billion". Still, the release gave no dollar figure for cost savings from the Parkland deal, so outsiders cannot tell how much of the beat came from wider refining margins versus deal savings.
What to watch: the exact 2026 Parkland cost-savings figure when the partnership reports fourth-quarter results. A number below the $125 million target set at the start of the year would show that high refining margins carried the outlook raise.
Debt Ratio Hit its Goal as Payouts Rose
Sunoco has grown by buying other fuel distributors and terminal operators, including Parkland last October and European storage business TanQuid in January. The partnership said it "Completes the acquisition of Offen Petroleum on October 27, 2026", adding another US fuel distribution network after the third quarter closed.
Even with that dealmaking, the partnership cut its net debt to 3.5 times Adjusted EBITDA, down from 3.7 times in the second quarter and 4.0 times in the first. Management noted that the business "returns to leverage target in less than one year following the acquisition of Parkland" while raising its quarterly cash payout for an eighth straight quarter to $1.0148 per unit, up 10.3% from a year ago.
What to watch: the net debt ratio in the fourth quarter after the Offen Petroleum purchase goes onto the balance sheet. An increase back toward 4.0 times would show that constant dealmaking keeps debt elevated despite rising cash profit.
🐻 Bear Case
Fuel Margins Slipped While Acquisitions Hid Underlying Trends
Fuel Distribution is Sunoco's largest business, selling 4.2 billion gallons of motor fuel this quarter. Segment Adjusted EBITDA more than doubled from a year ago to $523 million, which the partnership said happened "primarily due to the Parkland Acquisition and other acquisitions". Across the whole company, gross margin narrowed by 1.0 percentage point from a year ago to 7.1% because cost of sales — the wholesale cost of bought fuel — rose by 2.1 percentage points to 91.3% of revenue.
In the fuel segment itself, profit per gallon slipped to 16.8 cents, down from 17.1 cents in the second quarter and below the 17.0 to 17.7 cent range held since Parkland closed. Because each penny per gallon equals about $42 million of quarterly profit by our math, a return toward the 10.5 to 11.5 cent range seen before Parkland would erase a large share of recent gains. Meanwhile, the release gives no sales volume for stations owned a year ago.
What to watch: fourth-quarter fuel profit per gallon and total gallons sold once the comparison period includes two months of Parkland. A drop below 16 cents per gallon would confirm that the margin boost from market volatility is fading.
Taxes and Interest Took One-Third of Cash Profit
Buying Canadian and European operations brought Sunoco into tax-paying countries and added debt and preferred units to its balance sheet. While Adjusted EBITDA rose 6.8% from the second quarter to $1,049 million, Distributable Cash Flow, as adjusted — the cash left for unitholders after interest, current taxes and upkeep spending — fell 3.3% from the second quarter to $588 million.
- Current income tax expense: $138 million, up from $86 million last quarter and $4 million a year ago
- Cash interest and preferred unit payouts: $189 million and $29 million, up from $120 million and $4 million a year ago
- General partner share of payouts: $76 million, or 28.5% of the $267 million total cash distributed by our math
By our math, cash interest, current taxes and preferred payouts took 33.9% of Adjusted EBITDA this quarter, up from 26.2% a year ago. What to watch: current income tax expense in the fourth quarter, because another quarter above $100 million would show that foreign taxes permanently take a larger slice of cash flow.
Pipeline Profit Fell Without Prior-Period Payments
Pipeline Systems is the only Sunoco segment that Parkland did not transform, so it gives the cleanest view of the older midstream business. Daily volume rose 2.9% from a year ago to 1.33 million barrels, but Segment Adjusted EBITDA fell 8.8% from a year ago — and 12.6% from the second quarter — to $166 million.
Sunoco said segment profit dropped $4 million "primarily due to prior period contract deficiency payments", while profit from its ET-S Permian pipeline joint venture with parent Energy Transfer fell by $13 million. What to watch: ET-S Permian joint-venture earnings in the fourth quarter. A second straight drop would show that lower Permian pipeline returns are a lasting drag rather than a one-quarter dip.
Risks this quarter didn't answer
Three standing questions from prior quarters received no update in the third-quarter earnings release because they rely on conference call commentary or the full quarterly filing.
- Realized Parkland cost savings: the release gives no dollar figure against the $125 million full-year target; the conference call or fourth-quarter report will test it.
- Pipeline rate rules: no update on federal inflation index rules or rate appeals; the legal footnotes in the quarterly filing will show any change.
- Long-term fuel demand: no commentary on competition from electric vehicles; management remarks on the conference call are the only place this appears.
💲 Other KPIs
Cash available for payouts rose 80.4% from a year ago — and about 25% per common unit — after adding Parkland, following $535 million in the first quarter and $608 million in the second. It slipped 3.3% from the second quarter because current tax expense rose by $52 million and upkeep spending rose by $36 million.
Profit at the fuel storage terminals rose 62.7% from a year ago and 8.0% from the second quarter, up from $87 million in the fourth quarter, $107 million in the first and $113 million in the second. Daily volume reached 1.04 million barrels on the Parkland and TanQuid purchases plus better fuel-blending results.
Uncollected customer bills more than doubled from $1,972 million at the end of 2025, rising 116.5% by our math as quarterly revenue reached $18.0 billion. Accounts payable — bills Sunoco owes suppliers — rose by a smaller $1,444 million over the same nine months, tying up more working capital.
Total capital spending rose from $199 million in the first quarter and $202 million in the second, taking 1.3% of revenue by our math. The partnership spent $121 million on growth projects and $116 million on upkeep, leaving $248 million of growth spending for the fourth quarter to meet its $600 million annual floor.
🔮 Guidance
Raised. Sunoco now plans to beat the $3.7 billion top of its prior range, following a $400 million raise last quarter from its initial $3.1–3.3 billion plan. With $2.89 billion earned in the first nine months, beating $3.7 billion leaves at least $811 million for the fourth quarter by our math, down from $1,049 million in the third quarter on winter seasonality.
Unchanged. The partnership kept its long-term target of raising the cash payout by at least 5% a year. With the third-quarter payout up 10.3% from a year ago after eight straight quarterly raises of 1.25%, the full-year payout is running well ahead of the 5% floor.
❓ Key Questions
How much did Parkland cost savings add this quarter?
Sunoco plans to beat its $3.5–3.7 billion Adjusted EBITDA target, but the release gives no dollar figure for realized cost savings. Without it, investors cannot separate permanent deal savings from temporary refining margins.
What was fuel volume at stations owned a year ago?
Total fuel volume jumped to 4.2 billion gallons because of the Parkland purchase, hiding how older stations performed. A like-for-like volume number would show whether high pump prices are hurting customer demand.
Why did current income tax jump to $138 million?
Current tax expense rose from $86 million in the second quarter to $138 million, pulling distributable cash flow down despite higher operating profit. Investors need to know whether this reflects a one-time tax payment or the normal rate on Canadian and Caribbean earnings.
Will fourth-quarter growth spending double to hit $600 million?
Sunoco spent $352 million on growth projects in the first nine months against a full-year floor of at least $600 million. Hitting that floor requires $248 million in the fourth quarter, or double the third-quarter pace.
