Casella Waste Systems (CWST) Q3 2026 earnings review
Casella landfill volumes jump, but a canceled project erases profit
Casella Waste Systems, a Northeastern trash hauler and landfill operator, grew revenue through acquisitions and price hikes but swung to a bottom-line loss after canceling a New Hampshire landfill project. Sales from businesses owned a year ago rose 7% (total revenue grew 15%), while Adjusted EBITDA — operating profit before depreciation and one-offs — increased 11%. Chief executive Ned Coletta kept the full-year operating profit and cash flow plans unchanged at the middle of their ranges, so by our math fourth-quarter free cash flow must rise 55% to hit the target.
| Sales excluding acquisitions | +6.7% from a year ago (total revenue +15.2%) |
|---|---|
| Adjusted EBITDA | $133.5M +11.4% from a year ago (23.9% margin) |
| Landfill volume growth | +12.8% on top of +11.7% a year ago |
| Full-year profit outlook | Cut $10M Adjusted EBITDA held at $478M midpoint |
⚖️ Verdict: 🔴 Bearish
The story got worse because operational delays in the Mid-Atlantic region and a $13.6 million landfill write-off outweighed strong core pricing. Coletta acknowledged that Mid-Atlantic results lagged internal plans in the third quarter, forcing corporate intervention before regional margins improved in October, while acquisition debt and capital spending pushed nine-month free cash flow below last year. On the positive side, landfill volumes jumped 13% and initial staffing cuts plus new credit card fees reduced overhead costs as a share of sales.
The question now is whether October's margin rebound in the Mid-Atlantic marks a lasting turnaround or whether rapid acquisition spending is stretching management's ability to integrate deals and generate cash. If route consolidations and new fees hold, fourth-quarter operating margins and cash flow will step up sharply; if integration drags persist, acquisition dilution and rising interest costs will keep squeezing profit. Fourth-quarter free cash flow and segment margins will settle it.
🐂 Bull Case
Landfill Volumes Grew 13% Against a Tough Comparison
Casella relies on disposal scarcity in the Northeastern United States to fill its landfills and raise disposal prices. As competing municipal landfills and incinerators close across the region, the waste hauler aims to capture displaced trash at high incremental profit margins.
The company grew landfill disposal volumes by 12.8% from a year ago, adding $3.4 million in third-party revenue, while raising landfill prices by 4.6%. That volume gain came on top of an 11.7% jump in the third quarter of last year, proving that new waste streams are sticking rather than reflecting a one-time bump.
What to watch: fourth-quarter landfill volume growth and the pending airspace expansion permit at the Hakes construction and demolition landfill. Continued double-digit volume gains would confirm that regional competitor closures are permanently lifting disposal demand.
Overhead Efficiency and New Fees Lowered Administrative Costs
Chief executive Ned Coletta wants to reduce general and administrative overhead — corporate staff, billing systems and back-office expenses — below 11% of revenue over the next three years. This quarter the company moved from planning to execution by "completing the initial steps of our planned organizational transformation in late September and implementing credit card convenience fees throughout the quarter."
General and administrative expenses fell by 1.3 percentage points of revenue from a year ago to 10.5%, even after $1.4 million in severance and reorganization charges. Because customers now cover credit card processing fees and initial staffing cuts took effect at the end of September, Coletta expects fuller cost savings to show up in the fourth quarter.
What to watch: general and administrative spending as a share of revenue in the fourth quarter, when revenue is seasonally lower. Holding overhead near 11% in a smaller revenue quarter would show the structural cuts are working.
Higher Collection Prices Offset Lower Hauling Volumes
In its core hauling business, Casella prioritizes raising customer rates ahead of cost inflation, even when some customers leave over price. Solid waste pricing rose 5.5% from a year ago, led by a 5.9% increase in collection rates and a 5.0% increase at transfer stations, outpacing the company's 5.0% full-year pricing goal.
Higher rates more than made up for a 2.1% drop in collection volumes, which reduced revenue by $6.5 million while rate hikes added $18.4 million. Trading unprofitable hauling volume for higher prices protects route profitability, though it requires steady rate discipline as inflation cools.
What to watch: collection volume declines in the first half of 2027 as the company laps this year's route rationalization. Smaller volume losses alongside 5% pricing would show customer churn is stabilizing.
🐻 Bear Case
Granite State Cancelation Triggers Third Profit Outlook Cut
Developing new landfills in New England faces fierce local and legislative pushback, a risk that crystallized this quarter when Casella abandoned its proposed Granite State greenfield landfill in New Hampshire. The waste group wrote off $13.6 million in deferred project costs because the site was "no longer deemed viable in light of the outcome of legal proceedings, the changes in legislation and the unsupportive political environment."
- Third-quarter GAAP net loss: $7.0 million, down from $10.0 million of net income a year ago
- Profit excluding one-offs: $22.3 million, down 18.7% from a year ago on higher depreciation and interest
- Full-year net income outlook: cut for a third time to a loss of $4 million to $10 million, down from an initial $16 million to $22 million profit target
Even without the landfill write-off, profit excluding one-offs fell because acquisition borrowing pushed net interest expense up 30.5% to $18.2 million and depreciation rose 11.7%. Canceling Granite State removes a long-term disposal option in New England and shows that permitting setbacks carry real financial costs.
What to watch: court and regulatory rulings on the Juniper Ridge landfill expansion in Maine and the Hyland expansion in New York. Another permitting denial would threaten the company's regional disposal capacity before its Ontario landfill closes in 2028.
Mid-Atlantic Results Lagged Plan Before an October Rebound
Integrating acquired hauling operations in the Mid-Atlantic region is the centerpiece of Casella's plan to lift operating margins. "Although our results in the Mid-Atlantic were slightly behind plan in the quarter, we have seen a definitive positive inflection point in the region entering the fourth quarter," chief executive Ned Coletta said, pointing to October regional margins rising 1.5 percentage points from August after management stepped in to "strengthen regional leadership and provide corporate support to accelerate operational initiatives, including route consolidation and efficiencies."
The third-quarter numbers cut against that upbeat framing. Consolidated Adjusted EBITDA margin — operating profit before depreciation, amortization and one-offs — fell 0.8 percentage points from a year ago to 23.9%, as the cost of operations climbed 2.0 percentage points of revenue to 67.0%. Furthermore, management left the middle of its full-year Adjusted EBITDA outlook unchanged at $478 million while raising revenue by $5 million purely "to reflect higher floating fuel fees," which pass diesel costs to customers at zero profit margin.
What to watch: fourth-quarter consolidated Adjusted EBITDA margin, which by our math the full-year outlook puts at 22.8%, dead flat with a year ago. A reading above 22.8% is needed to prove the October Mid-Atlantic rebound lasted for a full quarter.
Acquisition Spending Drained Cash and Slowed Free Cash Flow
Casella spent $440.1 million in cash on six acquisitions during the first nine months of 2026, more than double the $217.5 million it spent in the same period last year. To fund those deals, the company drew down its cash reserves from $123.8 million at year-end to $11.7 million and borrowed a net $193.6 million in new debt.
At the same time, cash generation from existing operations slowed in the third quarter. Operating cash flow fell 13.6% from a year ago to $80.8 million, and Adjusted Free Cash Flow — operating cash flow minus regular capital spending, excluding acquisition and project outlays — dropped 32.2% to $33.0 million as capital expenditures rose 18.6% to $78.2 million. Over nine months, Adjusted Free Cash Flow is down 7.0% to $111.1 million, yet management kept its $200 million to $210 million full-year target.
What to watch: fourth-quarter Adjusted Free Cash Flow, which by our math must reach $93.9 million — a 55% jump from last year's fourth quarter — to hit the middle of the full-year plan. Falling short would show that working capital demands and higher interest payments are eating into cash conversion.
Risks this quarter didn't answer
The earnings release left three standing operational and regulatory risks without updated figures ahead of the quarterly filing.
- Mid-Atlantic segment operating loss: not broken out in the release; the quarterly filing's segment footnote will show whether the dollar loss narrowed from $3.9 million last quarter.
- Star Waste and Mountain State integration: no update on billing system conversions for this year's two largest acquisitions, which were previously sequenced behind the Mid-Atlantic.
- Hakes and Juniper Ridge permits: no mention of whether the Hakes landfill expansion permit arrived on schedule in the third quarter or how the Juniper Ridge court remand in Maine is progressing.
💲 Other KPIs
Total debt minus cash and restricted cash climbed by $432 million over the first nine months of 2026, up 43.3% from a year ago by our math. Casella used $205 million of cash reserves and $194 million of net debt borrowings to fund $440 million in acquisitions, pushing third-quarter net interest expense up 30.5% to $18.2 million.
Sales in Resource Solutions — the recycling processing and National Accounts brokerage unit — grew 11.5% from a year ago, following 10.7% growth in the second quarter. Higher prices added 4.5% and acquisitions added 3.8%, while growth in multi-site National Accounts (+3.3% volume) offset a 2.9% volume decline at recycling processing facilities.
Capital spending rose 18.6% from a year ago to 14.0% of revenue, up from 13.3% in the second quarter. Growth investments nearly doubled to $33.3 million as construction began on the Lehigh Valley recycling facility ($4.6 million) and upgrades continued on acquired truck fleets ($15.3 million), while replacement spending dipped 6.9% to $44.9 million.
🔮 Guidance
Raised. The company lifted the bottom of the range by $10 million, bringing the middle of the range to $2.105 billion, or 14.6% growth for the year. By our math, that leaves $544.7 million for the fourth quarter, up 16.1% from a year ago. It is the third raise this year — +$90M, +$30M, +$5M at the middle — and chief executive Ned Coletta said this move simply reflects higher fuel recovery fees.
Unchanged at the middle of the range. Management narrowed the band by $2 million on each side, keeping the midpoint at $478 million, or 13.1% annual growth. By our math, that leaves $124.2 million for the fourth quarter — up 16.1% from a year ago, compared with 11.4% growth in the third quarter — and implies a fourth-quarter margin of 22.8%, flat with last year.
Cut. The waste group lowered its bottom-line target by $10 million at the middle of the range after writing off $13.6 million on the canceled Granite State landfill project. It is the third cut in three quarters: the midpoint has dropped by $12M, $4M, and now $10M from an initial $19 million profit plan. By our math, the new target implies $1.8 million of net income in the fourth quarter.
Unchanged. The plan still calls for $375 million at the middle of the range, or 13.7% growth for the year. Because operating cash flow grew only 3.7% over the first nine months to $241.8 million, hitting the midpoint requires $133.2 million in the fourth quarter by our math, a 37.9% jump from a year ago.
Unchanged. Management kept the middle of the range at $205 million, up 13.9% for the full year. After a 32.2% drop in the third quarter left nine-month cash generation at $111.1 million, by our math the plan requires $93.9 million in the fourth quarter — up 55.3% from a year ago — aided by timing of capital spending and $265 million in planned full-year capital additions.
❓ Key Questions
What drove the Mid-Atlantic shortfall before October's rebound?
Chief executive Ned Coletta said the Mid-Atlantic region lagged internal plans in the third quarter, prompting leadership changes before margins jumped in October. Investors need the region's third-quarter revenue and operating loss to judge how much of the promised $5 million in 2026 cost savings was delayed.
How will fourth-quarter free cash flow jump 55%?
Adjusted Free Cash Flow is down 7% over nine months to $111.1 million, leaving $93.9 million needed in the fourth quarter to reach the $205 million full-year midpoint. Management has not explained whether working capital reversals or lower capital outlays will bridge that gap.
Did the Hakes landfill expansion permit arrive on schedule?
Last quarter management expected to receive a permit in the third quarter to expand airspace at the Hakes construction and demolition landfill by roughly 20 years. The earnings release did not mention Hakes or update the court remand at the Juniper Ridge landfill in Maine.
Where does the Star Waste systems integration stand?
Casella closed its $100 million annualized revenue acquisition of Star Waste in April and previously put its billing and routing migration behind the Mid-Atlantic effort. Now that corporate support was sent back into the Mid-Atlantic in the third quarter, the timeline for Star synergies is unclear.
