Waste Connections (WCN) Q3 2026 earnings review

Waste Connections raises its 2026 outlook, but cash flow lags

Waste Connections, the North American trash and oilfield waste hauler, grew faster in the third quarter even as its core price increases cooled. Total revenue rose 7% to $2.64 billion on higher recycling and oilfield waste activity, while landfill deliveries narrowed the drop in trash volumes. Chief executive Ronald J. Mittelstaedt raised the full-year revenue and profit outlook for a second time, and by our math the plan points to 6% revenue growth in the fourth quarter.

At a glance
Sales from solid waste businesses owned a year ago+4.5% +3.6% last quarter
Total revenue$2.64B +7.3% from a year ago
Profit per share, excluding one-offs$1.58 +9.7% from a year ago
Full-year revenue outlookRaised $55M to ~$10.09B (+6.6%)

⚖️ Verdict: ⚪ Neutral

The story is unchanged because stronger commodity and landfill revenue offset a steady slowdown in pricing and cash generation. Underlying solid waste margin expansion slowed to 0.5 percentage points, and nine-month free cash flow excluding one-offs rose less than 1%, leaving a steep fourth-quarter hurdle to meet the unchanged $1.40 billion cash target.

The question now is whether lower capital and landfill closure spending next year will lift cash flow before fading price increases squeeze profit margins. Either the end of renewable gas construction drives a cash rebound in 2027, or slowing price gains and higher interest costs eat up the savings. February's 2027 outlook for core price and capital spending will decide it.

🐂 Bull Case

🟢 strengthening GROWTH

Commodity and Oilfield Waste Lifted Revenue

Waste Connections collects trash from nine million customers, and it also treats oilfield waste and sells recycled materials and renewable fuel credits. Those commodity-linked lines drove the third-quarter revenue beat and the second full-year outlook raise.

  • Exploration and production (E&P) oilfield waste revenue: $212.9 million, up 18.8% from a year ago
  • Solid waste recycling revenue: $64.7 million, up 15.1% from a year ago
  • Intermodal and other revenue (which includes renewable fuel credits): $48.4 million, up 15.4% from a year ago

Recycling added 0.3 percentage points to underlying solid waste growth, reversing five straight quarters of declines. That rebound helped push total revenue up 7.3% to $2.64 billion, the fastest pace in the last five quarters.

What to watch: fourth-quarter recycling and oilfield waste revenue. Further gains there would add to the new $10.09 billion full-year revenue plan, because management's forecast assumes no further improvement in commodity or oilfield activity.

🟢 fading GROWTH

Landfill Activity Eased the Volume Decline

Solid waste unit volume — the amount of trash hauled and buried, excluding price changes and new acquisitions — has fallen for more than two years. In the third quarter, the drop narrowed from 1.9% in the second quarter to 1.2%.

"Sequential improvement of 70 basis points in solid waste unit volumes was led by an uptick in landfill volumes," chief executive Ronald J. Mittelstaedt said. Combined with 4.3% yield (average price per unit after customer turnover) and 1.3% from surcharges, sales from businesses owned a year ago grew 4.5%, up from 3.6% last quarter.

The volume concern is not gone, because unit volumes still shrank 1.2% from a year ago and 1.5% over the first nine months. One better quarter in landfill deliveries does not prove customer demand has turned positive across the collection routes.

What to watch: fourth-quarter unit volume in the solid waste internal growth table. Another smaller decline would show that customer losses from earlier price increases and fuel surcharges are fading.

🟢 strengthening CAPITAL ALLOCATION

Acquisitions Stepped Up as Buybacks Passed $1 Billion

Waste Connections grows by buying local haulers, and its revenue from recent deals had slowed for six straight quarters. In the third quarter, closed deals reached about $130 million in yearly revenue, up from $100 million at the end of June as the company completed its planned summer purchases.

Quarterly revenue from acquisitions rose to $53.4 million from $45.8 million in the second quarter, breaking the six-quarter slide. Meanwhile, the waste hauler raised its quarterly dividend by 10% to $0.35 per share and continued its "opportunistic share repurchases, bringing year to date outlays to over $1 billion for 2.5% of outstanding shares," Mittelstaedt said.

What to watch: full-year acquisition revenue closed by December. Additional deals closed in the fourth quarter are not in the updated 2026 outlook and would lift next year's starting revenue.

🟢 persistent PRODUCT

Positives this quarter didn't test

Two multi-year drivers from prior quarters received no new numbers in the third-quarter earnings release because management updates them on the call and in annual plans.

  • Artificial intelligence and technology program: a $100 million investment across seven projects aimed at adding 1 percentage point to the operating profit margin by 2028 and 2029; the fourth-quarter call will update deployment.
  • 2027 cash conversion step-up: the completion of renewable natural gas plant construction this year and lower landfill closure payments next year; the 2027 capital spending outlook in February will test this.

🐻 Bear Case

🔴🔴 persistent MARGIN contradicts narrative

Core Price and Underlying Margin Gains Kept Slowing

"Most importantly, we overcame a late quarter surge in diesel pricing to deliver adjusted EBITDA margin * of 34% on underlying margin expansion of 50 basis points," chief executive Ronald J. Mittelstaedt said. Adjusted EBITDA — earnings before interest, taxes, depreciation, amortization and one-offs — rose 7.9% to $895.8 million, and cost of operations fell 0.3 percentage points of revenue to 56.9%.

  • Core price (price increases net of rollbacks): 5.5% in Q3, down from 5.6% in Q2, 6.0% in Q1 and 6.3% a year ago
  • Underlying solid waste margin expansion: 0.5 percentage points in Q3, down from 0.7 in Q2, 1.1 in Q1 and 1.5 in Q4 2025
  • Fuel and material surcharges: 1.3% of growth in Q3, up from 1.1% in Q2 and -0.1% a year ago

Behind the 34.0% headline margin, the pricing and employee-retention gains that drove earlier quarters are wearing off. Core price has slowed for three straight quarters, while low-margin fuel surcharges carried more of the top line. Underlying margin expansion hit the bottom of management's 0.5 to 0.7 percentage point full-year target.

What to watch: fourth-quarter core price and the 2027 pricing outlook in February. By our math, the raised full-year outlook implies fourth-quarter adjusted EBITDA margin of 33.3%, down from 33.5% a year ago.

🔴🔴 persistent CASH

Cash Flow Lagged the Fourth-Quarter Hurdle

Waste Connections kept its full-year adjusted free cash flow plan at $1.40 billion to $1.45 billion and said it remains on track to "deliver double-digit growth in adjusted free cash flow * of at least $1.4 billion," according to Mittelstaedt. Yet third-quarter adjusted free cash flow — operating cash flow minus property and equipment spending and one-off items — barely moved.

  • Q3 adjusted free cash flow: $386.9 million, up 0.6% from $384.6 million a year ago
  • Nine-month adjusted free cash flow: $1,090.2 million, up 0.6% from $1,083.7 million a year ago
  • Implied Q4 adjusted free cash flow: $310 million to $360 million by our math, up 76% to 105% from $175.6 million in Q4 2025

Cash flow trailed profit growth because nine-month property and equipment spending rose 12.4% to $893.7 million, cash interest paid rose 17.5% to $281.0 million, and working capital used $201.6 million. Hitting the full-year cash target now requires Q4 capital spending to drop 7% from a year ago to $356 million by our math.

What to watch: fourth-quarter property and equipment spending and landfill closure cash payments. Any year-end spending above $356 million would push full-year free cash flow to the very bottom of the $1.40 billion range.

🔴 persistent DISCLOSURE

Risks this quarter didn't answer

Three regulatory and legal risks from prior quarters could not be tested from the earnings release alone.

  • Chiquita Canyon Landfill closure and lawsuits: nine-month cash flow shows $132.0 million in closure liability adjustments (minimal in Q3 after $138.0 million of first-half impairments), but Q3 cash outlays against the $100–150 million annual range and lawsuit updates wait for the quarterly filing.
  • Seneca Meadows Landfill expansion permit: final approval was targeted around year-end 2026; the conference call or fourth-quarter report will show whether the permit arrived.
  • New York City commercial waste zones: delayed to mid-to-late 2028, with no new timeline in the release.

🔮 Guidance

FY26 Revenue ~$10.09 billion
🠅 raised from $10.02–10.05 billion
⇘ decelerating

Raised. The full-year target moved up $55 million from the middle of the July range to 6.6% growth, following a $110 million raise in July. By our math, that leaves $2.52 billion for the fourth quarter, or 6.2% growth from a year ago, down from 7.3% in the third quarter as acquisition comparisons tighten.

FY26 Adjusted EBITDA ~$3.345 billion
🠅 raised from $3.33–3.34 billion
⇘ decelerating

Raised. The outlook for earnings before interest, taxes, depreciation, amortization and one-offs rose $10 million from the middle of the July range to 7.1% growth, after a $22.5 million raise in July. By our math, that leaves $840 million for Q4 (up 5.5% from a year ago) and a 33.3% margin, down from 34.0% in Q3.

FY26 Net income ~$1.18 billion
🠅 raised from $1.169–1.173 billion
⇘ decelerating

Raised. The reconciliation table sets full-year net income at $1.182 billion, up $11 million from the middle of the July range after the third quarter avoided large new landfill closure charges. By our math, that leaves $307 million for the fourth quarter, up 18.8% from $258.5 million a year ago.

FY26 Net cash provided by operating activities $2.64–2.69 billion
🠅 raised from $2.63–2.68 billion
⇗ accelerating

Raised. The operating cash flow range moved up $10 million to a middle of $2.662 billion, or 10.3% growth for the year. With $1.971 billion generated in the first nine months (up 6.1% from a year ago), the plan requires $691 million in the fourth quarter by our math, up 24.1% from $556.9 million in Q4 2025.

FY26 Adjusted free cash flow $1.40–1.45 billion
🠆 unchanged from $1.40–1.45 billion
⇗ accelerating

Unchanged. The plan still calls for 11.2% to 15.1% full-year growth despite higher revenue and operating profit targets. Because nine-month adjusted free cash flow rose only 0.6% to $1.090 billion, hitting the middle of the range requires $335 million in the fourth quarter by our math, nearly double last year's $175.6 million.

FY26 Capital expenditures ~$1.25 billion
🠆 unchanged from ~$1.25 billion
⇘ decelerating

Unchanged. Property and equipment spending stays at $1.25 billion, excluding $56.2 million spent on undeveloped land over the first nine months. With $893.7 million already spent on property and equipment (up 12.4% from a year ago), the plan leaves $356.3 million for the fourth quarter by our math, down 7.3% from Q4 2025.

❓ Key Questions

What drove the flat third-quarter free cash flow?

Adjusted free cash flow grew 0.6% in the third quarter to $386.9 million, leaving $310 million to $360 million for the fourth quarter to meet the $1.40–1.45 billion plan. How much did Chiquita Canyon Landfill closure payments cost in Q3, and what drops in Q4?

Where will core price settle in 2027?

Core price slowed to 5.5% in the third quarter from 6.3% a year ago, and underlying solid waste margin expansion slowed to 0.5 percentage points from 1.5 percentage points three quarters ago. Can pricing still beat internal wage and cost inflation next year?

Did oilfield and recycling gains lift profit margins?

Oilfield waste revenue grew 18.8% to $212.9 million and recycling jumped 15.1% to $64.7 million, but the release does not report profit by business line. How much of the 34.0% adjusted EBITDA margin came from those two lines rather than solid waste collection?

Is the Seneca Meadows expansion permit still on track?

Management previously expected final permit approval for the Seneca Meadows Landfill expansion around the end of 2026 while diverting trash by rail and truck. Has the state regulator met its milestones, or will diversion costs continue into 2027?
